Description

COOKING APPLIANCE

The present invention relates to a cooking appliance, and more particularly, to a cooking appliance providing both a cooking function and a hood function.

A cooking appliance is a type of home appliance for cooking food, installed in a kitchen space, and cooking food according to the user's intention. These cooking appliances can be classified in various ways depending on the heat source or form used, or the type of fuel used.

If we classify cooking appliances by the way they cook food, they can be classified into open and closed cooking appliances based on the shape of the space where the food is placed. Closed cooking appliances include ovens and microwave ovens, while open cooking appliances include cooktops and hobs.

A closed cooking appliance is a cooking appliance that seals the space where food is placed and heats the sealed space to cook the food. In a closed cooking appliance, a chamber, that is, a cooking chamber, which is a sealed space when food is placed and the food is to be cooked, is provided inside the main body. This cooking chamber actually becomes the space where the food is cooked. A heat source is provided in the interior or exterior space of the cooking chamber to heat the cooking chamber.

Among closed cooking appliances, a microwave oven is a cooking device that uses electricity to generate microwaves, which penetrate the food to be cooked inside the cooking chamber, causing molecular movement inside the food to heat the food.

Microwave ovens are kitchen appliances that heat the inside and outside of food simultaneously by irradiating it with high-frequency waves from a magnetron. They are widely used due to their advantages, such as high thermal efficiency, which greatly reduces the cooking time of food, reducing the loss of nutrients during the cooking, defrosting, and reheating processes of food, and allowing food to be cooked directly while stored in a container.

Recently, microwave ovens with hood functions, also known as OTR (Over the range) type microwave ovens, have been released. A microwave oven with hood functions to discharge air containing foreign substances (hereinafter referred to as “cooking gas”) generated during the cooking process in a cooking device installed below it to the outside or to discharge it indoors after filtering it.

These hood-type microwave ovens are equipped with a fan for sucking in and exhausting air. These fans are usually placed on the upper side of the cavity forming the cooking chamber. That is, in hood-type microwave ovens, the fan is usually placed at a higher position than the cavity.

However, if the fan is placed in the above position, the distance between the suction port located at the bottom of the hood-cum-microwave oven and the fan becomes longer than the vertical length of the cavity. If the distance between the suction port and the fan becomes longer, the cooking gas collection performance of the hood-cum-microwave oven is bound to decrease. This is because the flow rate of the suction airflow generated by the fan can decrease inversely proportional to the square of the distance from the fan.

In addition, if the fan is placed in the above location, the overall vertical length of the hood-cum-microwave oven will inevitably increase. If the vertical length of the hood-cum-microwave oven increases in this way, when the hood-cum-microwave oven is installed in the upper cabinet, there is a high possibility that the hood-cum-microwave oven will protrude further downward than the upper cabinet.

If the hood-compatible microwave oven protrudes further down than the upper cabinet, it not only looks bad, but the gap between the cooktop installed under the upper cabinet and the hood-compatible microwave oven may become narrower.

As the hood-type microwave oven protrudes below the upper cabinet, the gap between the cooktop and the hood-type microwave oven narrows, which may cause the hood-type microwave oven to block the view of the user using the cooktop and narrow the cooking area of the cooktop.

The present invention provides a cooking appliance having an improved structure that can provide a hood function while suppressing an increase in the vertical length of the entire cooking appliance.

Another object of the present invention is to provide a cooking appliance having an improved structure that can reduce the vertical length of the cooking appliance while suppressing an increase in the lateral and front-back length of the cooking appliance.

In this embodiment, it is exemplified that the magnetron and the power chamber (10b, 10c, 10d) are positioned at the side of the cooking chamber (10a). Power components such as a magnetron and a high-voltage transformer may be installed inside the power chamber (10b, 10c, 10d).

In addition, a control panel (25) may be provided on the front side of the main body (10). As an example, the control panel (25) may be placed on the door (20).

The control panel (25) may be formed in the form of a hexahedron having a predetermined internal space, and an input section may be provided on the front of the control panel (25) for the user to input an operation signal to operate the cooking appliance. A number of operation switches are provided in the input section, through which the user can directly input an operation signal.

As another example, the control panel (25) may be placed on the front side of the cavity (11). This control panel (25) may be placed in an area that does not overlap with the cooking chamber (10a) in the front-back direction. For example, the power chambers (10b, 10c, 10d) may be placed on the side of the cooking chamber (10a), and the control panel (25) may be placed on the front side of the power chambers (10b, 10c, 10d).

In addition, the cooking appliance of the present embodiment may further include a blower (100, 200). In addition, the main body (10) may be provided with an intake port (1) and an exhaust port (2, 3, 4).

The blower (100, 200) is accommodated inside the cooking appliance, and can suck in cooking gas through the intake port (1) and discharge the sucked cooking gas to the outside of the cooking appliance through the exhaust port (2, 3, 4).

[Intake, exhaust, space]

FIGS. 5 and 6 are rear perspective views showing the cooking appliance illustrated in FIG. 4 with the rear plate removed, and FIG. 7 is a rear view of the cooking appliance illustrated in FIG. 6.

Referring to FIGS. 3 to 7, the intake port (1) may be arranged on the bottom surface of the cooking appliance. As an example, the intake port (1) may be provided on the base plate (14). The intake port (1) may form a passage for the cooking gas to flow into the inside of the cooking appliance at the bottom of the cooking appliance. In this embodiment, it is exemplified that a pair of intake ports (1) are arranged on the lower side of the blower (100, 200).

The base plate (14) may be positioned at a predetermined distance downward from the bottom surface of the cavity (11). Accordingly, a lower space (symbol omitted) may be formed between the bottom surface of the cavity (11) and the base plate (14). By the lower space formed in this manner, a space necessary for external air to be introduced into the cooking appliance through the intake port (1) may be provided above the intake port (1).

The exhaust ports (2, 3, 4) can be arranged on the upper side of the cooking appliance. These exhaust ports (2, 3, 4) can form a passage on the upper side of the cooking appliance for discharging cooking gas sucked into the inside of the cooking appliance to the outside of the cooking appliance.

In this embodiment, it is exemplified that the cooking appliance is provided with a first exhaust port (2), a second exhaust port (3), and a third exhaust port (4).

The first exhaust port (2) and the second exhaust port (3) can be arranged on the upper surface of the main body (10). The first exhaust port (2) and the second exhaust port (3) can form a passage at the top of the cooking appliance for discharging cooking gas sucked into the inside of the cooking appliance to the outside of the cooking appliance.

As an example, the first exhaust port (2) and the second exhaust port (3) may be provided on the upper surface of the cabinet (13). The first exhaust port (2) and the second exhaust port (3) may be formed to penetrate the upper surface of the cabinet (13) in the vertical direction.

Among these, the first exhaust port (2) can be arranged on the rear side of the main body (10). And the second exhaust port (3) can be arranged on the front side of the main body (10). That is, the second exhaust port (3) is arranged on the side adjacent to the door (20) and can be arranged to be biased toward the front side compared to the first exhaust port (2).

The first exhaust port (2) can form a passage for discharging cooking gas sucked into the cooking appliance to the outdoors. And the second exhaust port (3) can form a passage for discharging cooking gas sucked into the cooking appliance to the indoors.

As an example, the first exhaust port (2) may be placed in an area that overlaps vertically with the upper storage cabinet installed on the upper side of the cooking appliance. And the second exhaust port (3) may be placed in a position that protrudes forward from the upper storage cabinet.

In addition, the first exhaust port (2) can be arranged approximately in the center of the lateral direction of the main body (10). And, on the front side of the main body (10), a plurality of second exhaust ports (3) can be arranged along the lateral direction.

As described above, the first exhaust port (2) arranged approximately in the center of the side of the main body (10) can be connected to an exhaust pipe connected to the outside. In addition, a plurality of second exhaust ports (3) arranged laterally can discharge cooking gas from the front side of the upper storage cabinet toward the upper side of the cooking appliance. At this time, the cooking gas can be discharged through the second exhaust port (3) in a filtered state inside the cooking appliance.

The third exhaust port (4), like the first exhaust port (2), can form a passage for discharging cooking gas sucked into the cooking appliance to the outdoors. The third exhaust port (4) can be positioned so as to face the wall on which the cooking appliance is installed. This third exhaust port (4) can be connected to an exhaust pipe installed on the wall and connected to the outdoors.

The third exhaust port (4) is arranged on the back of the cooking appliance and may be arranged above the blower (100, 200). As an example, the third exhaust port (4) may be provided in the rear plate (15). The third exhaust port (4) may be formed to penetrate the rear plate (15) in the front-back direction.

A space may be formed inside the main body (10). This space may be placed between the cavity (11) and the cabinet (13).

The above space portion can be divided into a side space portion (10e) and a rear space portion (10f). The side space portion (10e) can be arranged on each of the lateral sides of the cavity (11). And the rear space portion (10f) can be arranged on the rear side of the cavity (11).

For example, the side space (10e) may be a space formed between the side of the cavity (11) and the side of the cabinet (13). And the rear space (10f) may be a space formed between the back surface of the cavity (11) and the rear plate (15).

The side space (10e) and the rear space (10f) can be connected to the lower space. The side space (10e) and the rear space (10f) can be connected to the lower space in the vertical direction or in the lateral direction. The intake port (1) is connected to the lower space, and can be connected to the intake port (1) through the lower space of the side space (10e) and the rear space (10f).

In one of the side spaces (10e), a power unit (10b, 10c, 10d) may be arranged. In the present embodiment, it is exemplified that a power unit (10b, 10c, 10d) is arranged in a side space arranged on the rear side of the control panel (25).

In addition, a space may be formed inside the main body (10) that is located at the rear side of the cavity (11) and at the side side of the cavity (11). This space may be a rear space (10f), a side space (10e), or a main chamber (10b, 10c, 10d).

For example, the space may be arranged at a rear corner portion inside the main body (10). Hereinafter, the space arranged at the rear side of the main body (10b, 10c, 10d) will be referred to as a corner space (10e). The rear space (10f) and the side space (10e), more specifically, the rear space (10f) and the main body (10b, 10c, 10d), may be communicated through the corner space (10e).

The blower (100, 200) may be placed inside the main body (10). More specifically, the blower (100, 200) may be placed in a space, that is, a space between the cavity (11) and the cabinet (13). The blower (100, 200) may include at least one fan assembly (100, 200).

The fan assembly (100, 200) can generate an airflow to draw in cooking gas from outside the cooking appliance and then discharge it to the outside of the cooking appliance. This fan assembly (100, 200) can draw in cooking gas into the inside of the main body (10) through the intake port (1) and discharge the drawn-in cooking gas through the exhaust port (2, 3, 4).

At least one of the fan assemblies (100, 200) provided in the blower (100, 200) may be placed in the rear space (10f). Accordingly, the cooking gas introduced into the interior of the main body (10) through the intake port (1) may pass through the rear space (10f) and then be discharged through the first exhaust port (2) or the second exhaust port (3). The specific arrangement structure of the fan assemblies (100, 200) will be described later.

In addition, an upper space (10i) may be further provided inside the main body (10). The upper space (10i) may be placed on the upper side of the cavity (11).

For example, the upper space (10i) can be formed between the upper surface of the cavity (11) and the upper surface of the cabinet (13). This upper space (10i) can be connected to the rear space (10f).

That is, air drawn into the rear space (10f) can pass through the upper space (10i) and be discharged outside the cooking appliance through the exhaust ports (2, 3, 4). In addition, air drawn into the side space (10e) can also pass through the rear space (10f) and the upper space (10i) and be discharged outside the cooking appliance through the exhaust ports (2, 3, 4).

[Fan Assembly]

FIG. 8 is a perspective view illustrating the rear fan assembly illustrated in FIG. 6 in an exploded manner, and FIG. 9 is a perspective view illustrating the corner fan assembly illustrated in FIG. 6 in an exploded manner.

Referring to FIG. 1 and FIG. 7 to FIG. 8, the blower (100, 200) may include at least one fan assembly (100, 200). As an example, the blower (100, 200) may include a rear fan assembly (100).

The rear fan assembly (100) may include a fan housing (110), an impeller (120), and a fan motor.

The fan housing (110) forms the exterior of the rear fan assembly (100) and can accommodate an impeller (120) inside. A first intake port (112) can be formed on the side of the fan housing (110). The first intake port (112) can form a passage in the fan housing (110) necessary for air outside the rear fan assembly (100) to be sucked into the interior of the impeller (120).

In this embodiment, the fan housing (110) is exemplified as being formed in a shape including a lying cylindrical shape with both sides open, and the open sides of the fan housing (110) can be provided as a first suction port (112).

A space for accommodating an impeller (120) can be formed inside the fan housing (110).

A receiving space for receiving an impeller (120) may be formed inside the fan housing (110). In addition, the inner surface of the fan housing (110) facing this receiving space may be formed as a curved surface that surrounds the outer surface of the impeller (120).

The first discharge port (114) may be provided on the upper side of the fan housing (110). The first discharge port (114) forms a passage through which air sucked into the accommodation space where the impeller (120) is accommodated is discharged to the outside of the blower (100, 200).

The above first discharge port (114) may be formed in a form that penetrates the fan housing (110) in the vertical direction. Accordingly, air sucked laterally into the fan housing (110) through the first suction port (112) may be discharged to the upper side of the fan housing (110) through the first discharge port (114).

The impeller (120) is configured to be rotatable around an axis extending laterally. A space is formed inside the impeller (120) into which air is sucked in through the side of the impeller (120).

The above impeller (120) can be connected to the rotation axis of the fan motor. The rotation axis of the fan motor rotates around an axis that extends laterally, and the impeller (120) connected to the rotation axis of the fan motor can rotate around an axis that extends laterally together with the rotation axis of the fan motor.

The rear fan assembly (100) provided as described above is arranged inside the main body (10), and may be arranged in at least one of the rear space (10f) and the corner space (10e). In this embodiment, the rear fan assembly (100) is exemplified as being arranged in the rear space (10f).

As an example, the rear fan assembly (100) may be provided in a form including a pair of impellers (120). This rear fan assembly (100) may be provided in a form in which a fan motor is arranged between a pair of impellers (120) arranged laterally.

In the rear fan assembly (100), the fan motor can rotate a pair of impellers (120) arranged on both sides thereof together. And each impeller (120) can be accommodated inside a pair of fan housings (110) arranged on both sides of the fan motor.

As described above, the rear fan assembly (100) including one fan motor, a pair of impellers (120) and a fan housing (110) can suck in air through a pair of first intake ports (112) arranged on each of the lateral sides of the rear fan assembly (100) and discharge air through a pair of first discharge ports (114) arranged on the upper side of the rear fan assembly (100).

The above rear fan assembly (100) may be provided in a form in which a pair of impellers (120) and a fan housing (110) are arranged on both sides of a fan motor. Hereinafter, the assembly of the impeller (120) and the fan housing (110) will be referred to as a "fan module." Accordingly, it can be said that each rear fan assembly (100) is provided in a form in which a pair of fan modules are connected on both sides of a fan motor.

The rear fan assembly (100) above can be placed in the rear space (10f), that is, the space formed between the rear surface of the cavity (11) and the rear plate (15). This rear fan assembly (100) can be placed in a space that is connected to the intake port (110) and the exhaust port (2, 3, 4), and can suck in air through the intake port (110) and discharge air toward the exhaust port (2, 3, 4).

In addition, the rear fan assembly (100) can be placed at the lateral center of the rear space (10f). That is, the rear fan assembly (100) can be placed approximately at the rear center inside the cooking appliance.

According to the present embodiment, the first exhaust port (2) may be arranged at approximately the center of the side of the main body (10), but may be arranged at a position tilted rearward on the upper surface of the cabinet (13). In addition, the first exhaust port (2) may be arranged in an area that overlaps vertically with the fan assembly (100, 200). That is, the first exhaust port (2) may be arranged in an area that overlaps vertically with the rear space (10f) and the rear fan assembly (100).

In addition, the third exhaust port (4) may be positioned approximately in the lateral center of the main body (10), but may be positioned upwardly from the rear plate (15). That is, the third exhaust port (4) may be positioned on the rear surface of the main body (10), but may be positioned adjacent to the first exhaust port (2).

In the cooking appliance of the present embodiment, the first exhaust port (2), the third exhaust port (4) and the rear fan assembly (100) are all arranged in the rear space (10f), and the first exhaust port (2) and the third exhaust port (4), particularly the first exhaust port (2), can be arranged in the vertical direction with the rear fan assembly (100) on the rear space (10f).

That is, the rear fan assembly (100), the rear space (10f), the first exhaust port (2), and the third exhaust port (4) can be arranged in positions that overlap in the vertical direction. Preferably, the rear fan assembly (100), the rear space (10f), the first exhaust port (2), and the third exhaust port (4) can be arranged in a row in the vertical direction.

Accordingly, the air flow caused by the operation of the rear fan assembly (100) can be made in the same straight direction as the arrangement direction of the rear fan assembly (100), the rear space (10f), the first exhaust port (2), and the third exhaust port (4).

As air flows in a straight direction like this, the resistance to air flow is lowered, allowing air to flow more smoothly. Accordingly, the air intake and exhaust performance by the rear fan assembly (100) can be improved, and thus the cooking gas removal performance of the cooking appliance can be improved accordingly.

The blower (100, 200) of the present embodiment may include a plurality of fan assemblies (100, 200) arranged laterally. As an example, the blower (100, 200) may further include a corner fan assembly (200), as shown in FIGS. 7 and 9. The rear fan assembly (100) and the corner fan assembly (200) may be arranged laterally in the rear space (10f).

The corner fan assembly (200) may be provided in a form in which one fan module is connected to a fan motor. As an example, the corner fan assembly (200) may be provided in a form in which one fan module is connected to the lower side of the fan motor.

In this corner fan assembly (200), the impeller (220) can be rotated around an up-down axis. The second suction port (212) can be arranged on the lower side of the fan housing (210), and the second discharge port (224) can be arranged on the side of the fan housing (210).

That is, the corner fan assembly (200) can be provided in a shape similar to a shape in which roughly half of the rear fan assembly (100) is erected vertically.

In the rear space (10f), a rear fan assembly (100) and a corner fan assembly (200) may be arranged together. As an example, the rear fan assembly (100) and the corner fan assembly (200) may be arranged laterally in the rear space (10f).

For example, the corner fan assembly (200) may be placed on the side adjacent to the main chamber (10b, 10c, 10d), and the rear fan assembly (100) may be placed on the side adjacent to the side space (10e) on the opposite side.

At least a portion of the corner fan assembly (200) may be placed in the corner space portion (10e). As an example, most of the area of the corner fan assembly (200) may be placed in the corner space portion (10e), and the second intake port (212) of the corner fan assembly (200) may also be placed in the corner space portion (10e). The corner fan assembly (200) may be placed laterally spaced apart from the rear fan assembly (100) by a predetermined distance.

According to the present embodiment, instead of including only a plurality of rear fan assemblies (100), the blower (100, 200) may include both a rear fan assembly (100) and a corner fan assembly (200).

As the rear fan assembly (100) and the corner fan assembly (200) are applied together to the blower (100, 200) in this way, the lateral length of the entire blower (100, 200) can be reduced compared to a case where the blower (100, 200) includes only a plurality of rear fan assemblies (100).

For example, compared to a blower (200) including a pair of rear fan assemblies (100) arranged laterally, the lateral length of a blower (100, 200) including one rear fan assembly (100) and one corner fan assembly (200) can be measured shorter.

The corner fan assembly (200) includes only a portion of the fan modules included in the rear fan assembly (100), and is provided in a form that includes fan modules that are vertically erected. Therefore, the lateral length of the corner fan assembly (200) cannot but be much shorter than that of the rear fan assembly (100) and the rear fan assembly (100).

Considering these points, it can be said that the blower (100, 200) of the present embodiment including the corner fan assembly (200) can be provided in a significantly smaller size compared to the blower including only the rear fan assembly (100) or the rear fan assembly (100).

When a blower (100, 200) of this type is applied to a cooking appliance, the size of the cooking appliance, especially the lateral length of the cooking appliance, can be reduced as the space occupied by the blower (100, 200) becomes smaller.

Considering these points, when the size of the cooking appliance is slightly small for arranging multiple rear fan assemblies (100) inside the cooking appliance, the blower (100, 200) of the present embodiment is very suitable for application to the cooking appliance.

In addition, in the corner fan assembly (200), the second suction port (212) may be positioned at the lower side of the fan housing (210). Accordingly, the second suction port (212) may be positioned at the lowest end of the corner fan assembly (200) and may be positioned very close to the suction port (1) provided at the bottom of the cooking appliance.

Considering that the suction performance of the fan assembly can be significantly improved compared to the output of the fan motor as the distance between the second suction port (212) and the suction port (1) becomes closer, it can be seen that the suction performance of the corner fan assembly (200) can be significantly improved as the second suction port (212) of the corner fan assembly (200) becomes closer to the suction port (1).

That is, although the performance of the corner fan assembly (200) may be lower than that of the rear fan assembly (100), this performance difference can be largely offset by the performance improvement obtained by shortening the distance between the second intake port (212) and the intake port (1).

Considering these points, it can be evaluated that the blower (100, 200) of the present embodiment can provide a cooking gas removal performance that is at least as good as that of other types of blowers while contributing to the miniaturization of the cooking appliance.

The cooking appliance of the present embodiment including the blower (100, 200) as described above can provide improved cooking gas removal performance while maintaining a compact size.

Meanwhile, referring to FIGS. 5 to 7, the rear fan assembly (100) and the corner fan assembly (200) can be positioned to overlap the cavity (11) in the front-rear direction. That is, the rear fan assembly (100) and the corner fan assembly (200) can be positioned between the upper surface and the lower surface of the cavity (11) in the up-down direction.

In order for the air that has entered the interior of the main body (10) through the intake port (1) to smoothly move toward the rear fan assembly (100) or the corner fan assembly (200), a certain distance must be secured between the rear fan assembly (100) and the corner fan assembly (200) and the intake port (1).

In addition, in order for the air discharged from the rear fan assembly (100) and the corner fan assembly (200) to move smoothly toward the upper space (10i), it is preferable that the rear fan assembly (100) and the corner fan assembly (200) be positioned lower than the upper space (10i).

When the rear fan assembly (100) and the corner fan assembly (200) are positioned higher than the upper space (10i), a problem may occur in which the passage between the first discharge port (114) of the rear fan assembly (100) or the corner fan assembly (200) and the upper space (10i) becomes too narrow.

Considering these points, in this embodiment, the rear fan assembly (100) and the corner fan assembly (200) are arranged at positions where the rear fan assembly (100) and the corner fan assembly (200) and the intake port (1) and the rear fan assembly (100) and the corner fan assembly (200) and the upper space (10i) can be appropriately spaced apart.

Accordingly, the air flow from the intake port (1) to the rear fan assembly (100) and the corner fan assembly (200) and the air flow from the rear fan assembly (100) and the corner fan assembly (200) to the upper space (10i) can be smoothly achieved.

In addition, the corner fan assembly (200) can be positioned closer to the intake port (1) than to the exhaust port (113, 115, 117). Accordingly, the second intake port (212) of the corner fan assembly (200) can be positioned very close to the intake port (1). As a result, the intake performance of the corner fan assembly (200), which is relatively small in size and has low output compared to the rear fan assembly (100), can be effectively improved.

[Example of absence of euro formation]

Fig. 10 is a rear perspective view illustrating the flow path forming member illustrated in Fig. 6 in isolation, and Fig. 11 is a rear perspective view illustrating a cooking appliance to which another example of the flow path forming member is applied. In addition, Fig. 12 is a rear perspective view illustrating the flow path forming member illustrated in Fig. 11 in isolation, and Fig. 13 is a rear perspective view illustrating the air flow state in a cooking appliance according to the first embodiment of the present invention.

Referring to FIGS. 5 to 7 and 10, the cooking appliance may include a flow forming member (30). The flow forming member (30) is provided to induce the flow of air discharged from the blower (100, 200).

The exhaust path (30) can form an exhaust path (A) inside the cooking appliance. The exhaust path (A) can connect between the blower (100, 200) and the upper space (10i), and is provided to guide air flow from at least one of the rear fan assembly (100) and the corner fan assembly (200) to the upper space (10i). This exhaust path (A) can guide the flow of air discharged from the blower (100, 200) toward the exhaust port (2, 3, 4).

As an example, the exhaust path (A) may be arranged in the rear space (10f). The inlet of the exhaust path (A) may be opened toward the blower (100, 200). For example, the inlet of the exhaust path (A) may be opened toward the first discharge port (114) of the rear fan assembly (100) and the second intake port (214) of the corner fan assembly (200). And the outlet of the exhaust path (A) may be opened toward the upper space (10i).

The exhaust path (A) can be formed inside the cooking appliance as a path that guides air flow from the first outlet (114) of the rear fan assembly (100) to the upper space (10i). In addition, the exhaust path (A) can be formed inside the cooking appliance as a path that guides air flow from the second intake port (214) of the corner fan assembly (200) to the upper space (10i).

As an example, at least a portion of the exhaust path (A) may be formed by the first path plate (31). The first path plate (31) may form a wall that blocks the first intake port (112) and the first discharge port (114) of the rear fan assembly (100).

This first euro plate (31) is arranged in the rear space (10f) and can be arranged on the upper side of the rear fan assembly (100). That is, the first euro plate (31) can form a wall blocking the first intake port (112) and the first discharge port (114) on the upper side of the rear fan assembly (100).

According to the present embodiment, the rear space (10f) may have a rear fan assembly (100) and corner spaces (10g, 10h) arranged laterally. In the rear space (10f), the first suction ports (112) may be arranged on each of the lateral sides of the rear fan assembly (100). In addition, the first discharge port (114) may be arranged between a pair of first suction ports (112) arranged laterally spaced apart from each other by a predetermined interval, and may be arranged on the upper surface of the rear fan assembly (100).

If one of the pair of first suction ports (112) positioned closer to the corner space (10g, 10h) is referred to as the left first suction port (112), the first flow plate (31) is arranged to form a wall that blocks the space between the first discharge port (114) and the right first suction port (112). This first flow plate (31) can be positioned at a position that is tilted toward the right first suction port (112) from the lateral center of the rear fan assembly (100), that is, at a position adjacent to the right first suction port (112).

Hereinafter, the direction toward the main chamber (10b, 10c, 10d) along the lateral direction from the lateral center of the cooking appliance is referred to as the left, and the direction toward the side space (10e) located on the opposite side is referred to as the right.

The above first flow plate (31) can form a vertical wall extending upward from the upper surface of the rear fan assembly (100) where the first discharge port (114) is formed toward the upper space (10i). This first flow plate (31) can define the right boundary surface of the exhaust flow path (A).

Meanwhile, the cooking appliance of the present embodiment may further include an expansion plate (18). The expansion plate (18) may be arranged to block the space between the upper space (10i) and the rear space (10f).

At least a portion of the expansion plate (18) may be placed in the rear space (10f). At least a portion (18a; hereinafter referred to as “rear compartment”) of the expansion plate (18) placed at the corresponding position may be placed between the rear fan assembly (100) and the upper space (10i) in the vertical direction. In addition, the rear compartment (18b) of the expansion plate (18) may be placed between the rear surface of the cavity (11) and the rear plate (15) in the forward-backward direction.

The rear compartment (18b) of the expansion plate (18) arranged in this manner covers a portion of the rear space (10f) at a position higher than the rear fan assembly (100) and blocks a portion of the rear space (10f) and the upper space (10i).

In this embodiment, it is exemplified that the area between the right side of the rear space (10f) and the upper space (10i) is blocked by an expansion plate (18).

The above expansion plate (18) and the rear fan assembly (100) are spaced apart in the vertical direction, and thus a lateral passage is formed between the expansion plate (18) and the rear fan assembly (100). The lateral passage formed at this time can connect between the right area covered by the expansion plate (18) among the rear space portion (10f) and the upper area of the rear fan assembly (100) where the exhaust path (A) is formed.

The first euro plate (31) may form a vertical wall extending upward from the rear fan assembly (100) toward the expansion plate (18). As an example, the first euro plate (31) may form a vertical wall connecting the upper surface of the rear fan assembly (100) and the side edge of the expansion plate (18). At least a portion of the first euro plate (31) may protrude upward from the expansion plate (18).

As described above, the first flow plate (31) connected to the expansion plate (18) can form a vertical wall that blocks a lateral passage formed between the rear fan assembly (100) and the expansion plate (18). That is, the first flow plate (31) can form a wall in the rear space (10f) that blocks air flow between the right area of the rear space (10f) and the exhaust path (A).

In addition, the euro forming member (30) may further include a second euro plate (32). The second euro plate (32) may form a wall that blocks the first intake port (112) and the first discharge port (114) of the rear fan assembly (100).

The second euro plate (32) may be placed on the left side of the rear fan assembly (100). Accordingly, the rear fan assembly (100) may be placed between the first euro plate (31) and the second euro plate (32) in the lateral direction.

In the lateral direction, the second euro plate (32) can be arranged between the rear fan assembly (100) and the corner fan assembly (200). The second euro plate (32) can form a wall that blocks the first intake port (112) and the first discharge port (114), and at the same time, form a wall that blocks the second intake port (214) of the corner fan assembly (200) and the first intake port (112) of the rear fan assembly (100).

In the corner fan assembly (200), the second intake port (212) is arranged toward the intake port (1), i.e., downward. And the second intake port (214) is arranged toward the direction toward the rear fan assembly (100), i.e., toward the side, more specifically, toward the right side, so as to be connected to the exhaust path (A).

The second flow plate (32) can be arranged on the right side of the second intake port (214) to define the lower boundary surface of the exhaust path (A). This second flow plate (32) can define the lower boundary surface of the exhaust path (A) between the rear fan assembly (100) and the corner fan assembly (200). At this time, the lower boundary surface of the exhaust path (A) defined by the second flow plate (32) can form an inclined surface whose height changes along the lateral direction.

According to the present embodiment, the second suction port (214) may be arranged to face the first suction port (112) which is arranged to face the corner fan assembly (200). In addition, the first discharge port (114) may be arranged above the first suction port (112) and may be arranged above the second suction port (214).

As an example, the second euro plate (32) may form an inclined surface that extends laterally from the lower side of the second suction port (214) toward the upper side of the first suction port (112). For example, the second euro plate (32) may extend laterally upwardly from a lateral end adjacent to the corner fan assembly (200) toward the rear fan assembly (100).

One lateral end of the second euro plate (32) may be placed below the second suction port (214). For example, the left end of the second euro plate (32) may be placed at a lower position than the second suction port (214).

In addition, the lateral end of the second euro plate (32) may be placed above the first suction port (112). For example, the right end of the second euro plate (32) may be placed at a higher position than the first suction port (112).

The second flow plate (32) can form an inclined wall that blocks between the first suction port (112) and the first discharge port (114), and between the first suction port (112) and the second suction port (214). That is, the second flow plate (32) can form an inclined wall between the rear fan assembly (100) and the corner fan assembly (200), and this wall can block not only between the first suction port (112) and the first discharge port (114), but also between the first suction port (112) and the second suction port (214).

Accordingly, between the rear fan assembly (100) and the corner fan assembly (200), air discharged from the first discharge port (114) does not flow into the first suction port (112), and air discharged through the second suction port (214) does not flow into the first suction port (112).

That is, the second euro plate (32) can form a wall between the rear fan assembly (100) and the corner fan assembly (200) that blocks the air flow from the first discharge port (114) and the second suction port (214) to the first suction port (112).

According to the present embodiment, an exhaust path (A) may be formed on the left side of the first flow plate (31) and the upper side of the second flow plate (32). The intake port (1) may be arranged on the lower side of the exhaust path (A). In addition, with respect to the vertical direction, the first intake port (112) and the second intake port (212) may be arranged between the intake port (1) and the exhaust path (A), and the first discharge port (114) and the second intake port (214) may be arranged between the exhaust path (A) and the upper space (10i).

The first discharge port (114) and the second suction port (214) can be connected to the exhaust path (A). The first discharge port (114) can be arranged upward and connected to the exhaust path (A). And the second suction port (214) can be arranged sideways and connected to the exhaust path (A).

In addition, the second euro plate (32) may form a path that guides the air intake into the first intake port (112).

As an example, the second flow plate (32) is arranged on the upper side of the intake port (1) and can be arranged on the left side and upper side of the first intake port (112). This second flow plate (32) can form the left side and upper side boundary surface of the flow path connecting the intake port (1) and the first intake port (112). By the second flow plate (32) provided in this way, air can be effectively induced to flow into the first intake port (112) from the left side of the rear fan assembly (100).

Meanwhile, the euro forming member (30) may further include a fastening plate (33). The fastening plate (33) may be installed in the rear fan assembly (100).

As an example, the fastening plate (33) may be coupled to the upper surface of the rear fan assembly (100) with the first discharge port (114) opening upward. This fastening plate (33) may be arranged above the first suction port (112) and may be arranged above the second suction port (212) and the second suction port (214).

According to the present embodiment, the first euro plate (31) may be provided in a form that extends upward from the fastening plate (33). In addition, the second euro plate (32) may be provided in a form that extends downward from the fastening plate (33). That is, the upper end of the second euro plate (32) may be connected to the fastening plate (33).

In this way, the first euro plate (31) and the second euro plate (32) connected to the fastening plate (33) can be connected to the rear fan assembly (100) via the fastening plate (33).

In addition, the fastening plate (33) can be placed between the first euro plate (31) and the second euro plate (32) to connect the first euro plate (31) and the second euro plate (32). As an example, the euro forming member (30) can be provided in a form in which the first euro plate (31), the second euro plate (32) and the fastening plate (33) are formed integrally.

In the euro-forming member (30) provided in this form, the first euro plate (31) and the second euro plate (32) do not need to be separately connected to the rear fan assembly (100), and the installation of the first euro plate (31) and the second euro plate (32) can be easily and quickly accomplished by the fastening plate (33) connected to the rear fan assembly (100).

A discharge hole (symbol omitted) may be formed in the fastening plate (33). The first discharge port (114) may be exposed to the upper side of the fastening plate (33), i.e., the inside of the exhaust path (A), through this discharge hole.

In addition, the cooking appliance of the present embodiment may further include a support member (40). The support member (40) is provided to support the corner pan assembly (200). At least a portion of the support member (40) may be placed in the corner space portion (10g, 10h).

As an example, the support member (40) may include a lateral support member (41). The lateral support member (41) may be arranged on a lateral side of the corner fan assembly (200). The lateral support member (41) may form a side surface of the support member (40), more specifically, a right side surface of the support member (40).

The lateral support member (41) can form a vertical wall that covers the corner fan assembly (200) from the side. For example, the lateral support member (41) can form a vertical plane that is perpendicular to the lateral axis. The lateral support member (41) can form a wall that blocks the corner fan assembly (200) and the rear fan assembly (100) in the rear space (10f).

The lateral support member (41) can be placed between the corner fan assembly (200) and the second flow plate (32). This lateral support member (41) can define the left boundary surface of the exhaust flow path (A).

A discharge hole (omitted) may be formed in the lateral support member (41). The second suction port (214) may be exposed to the right side of the lateral support member (41), i.e., the inside of the exhaust path (A), through this discharge hole.

In addition, the cooking appliance of the present embodiment may further include a connecting passage forming member (37, 38). The connecting passage forming member (37, 38) may be arranged on the upper side of the corner pan assembly (200). The connecting passage forming member (37, 38) may partition the rear space (10f) such that a portion of the rear space (10f) around the support member (40) is separated into a connecting passage part (39).

As an example, the connecting path forming member (37, 38) may include a first compartment (37) and a second compartment (38).

The first compartment (37) can form a vertical wall that is arranged at a predetermined interval on the side of the support member (40). As an example, the first compartment (37) can form a vertical wall that is arranged at a predetermined interval on the side of the lateral support member (41). With respect to the lateral direction, the first compartment (37) can be arranged between the corner fan assembly (200) and the rear fan assembly (100).

The second compartment (38) can form a wall connecting the lateral support (41) and the first compartment (37). As an example, the first compartment (37) can be positioned at a predetermined distance to the right from the lateral support (41). The second compartment (38) can form a wall connecting the lower end of the first compartment (37) and the lateral support (41).

As an example, the second compartment (38) may be arranged on the upper side of the second euro plate (32). The left end of the second compartment (38) may be connected to the lateral support member (41). In addition, the left end of the second compartment (38) may be arranged to be spaced apart from the left end of the second euro plate (32) in the vertical direction with the second suction port (214) interposed therebetween.

As an example, the second compartment (38) may form an inclined surface parallel to the second flow plate (32). This second compartment (38), together with the lateral support portion (41), defines the left boundary surface of the exhaust passage (A), and may guide the flow of air discharged from the second intake port (214) to the exhaust passage (A) toward the lateral center of the exhaust passage (A).

The first compartment (37) can extend upward from the second compartment (38) and, together with the lateral support (41) and the second compartment (38), can define the left boundary surface of the exhaust path (A). This first compartment (37) can guide the flow of air flowing in the exhaust path (A) toward the upper space (10i).

When the operation of the blower (100, 200) begins, as shown in FIGS. 8 to 10 and 13, an intake airflow can be formed to suck air from outside the cooking appliance into the inside of the cooking appliance. The intake airflow formed in this manner acts on the outside air to be sucked in through the intake port (1) arranged at the bottom of the cooking appliance. The outside air around the intake port (1), i.e., the cooking gas, can be sucked into the inside of the main body (10) by passing through the intake port (1) by the intake airflow acting in this manner.

And the cooking gas sucked into the interior of the main body (10) in this way can be introduced into the interior of the rear space (10f) among the spaces inside the main body (10). The cooking gas sucked into the interior of the rear space (10f) in this way can be sucked into the interior of the rear fan assembly (100) and the corner fan assembly (200) through the first suction ports (112) arranged on both sides of the rear fan assembly (100) and the suction ports arranged on the lower side of the corner fan assembly (200), respectively.

At this time, air intake into the rear fan assembly (100) can be guided by at least a part of the directional forming member (30). Specifically, air intake into the first intake port (112) arranged on the left side of the rear fan assembly (100) can be guided by the second directional plate (32).

The air sucked into the rear fan assembly (100) and the corner fan assembly (200) can be discharged through the first discharge port (114) and the second suction port (214), respectively. The flow of the air discharged in this manner can be guided by the exhaust path (A).

Air discharged from the second discharge port (214) of the corner fan assembly (200) can flow toward the upper space (10i) through the rear space (10f) via the exhaust path (A). Around the second discharge port (214), the exhaust path (A) can form an inclined passage that extends upward from the second discharge port (214).

The upwardly oriented passage formed in this manner lowers the resistance to air flow in the exhaust path (A) and minimizes flow loss inside the cooking appliance. This upwardly oriented passage can be formed by a second flow plate (32) defining a lower boundary surface of the exhaust path (A) on the right side of the second suction port (214) and a connecting flow path forming member (37, 38) defining a left boundary surface of the path.

In addition, air discharged from the first discharge port (114) of the rear fan assembly (100) can flow toward the upper space (10i) through the exhaust path (A) and through the rear space (10f). At this time, the exhaust path (A) can guide the air flow so that the air discharged through the first discharge port (114) can flow toward the upper space (10i) without spreading to the surroundings.

[Other examples of euro formation absence]

Referring to FIGS. 11 and 12, the euro-forming member (35) may further include an extension plate (34). The extension plate (34) may form a wall blocking the first suction port (112) and the first discharge port (114).

The extension plate (34), like the second euro plate (32a), may be arranged on the left side of the rear fan assembly (100). The extension plate (34) may be arranged on the upper side of the rear fan assembly (100), and the second euro plate (32a) may extend downward from the extension plate (34). As an example, the extension plate (34) may be arranged on the upper side of the second euro plate (32a), and may be provided in a form that extends upward from the second euro plate (32a).

In the lateral direction, the rear fan assembly (100) may be arranged between the extension plate (34) and the first flow path plate (31). In addition, in the lateral direction, the extension plate (34) may be arranged between the rear fan assembly (100) and the corner fan assembly (200). In addition, in the lateral direction, the extension plate (34) may be arranged between the lateral support member (41) and the fastening plate (33), and between the connecting flow path forming member (35) and the fastening plate (33).

The extension plate (34) arranged in this manner can be arranged between the lateral support member (41) and the first flow path plate (31) inside the exhaust flow path (A), and between the connecting flow path forming member (35) and the first flow path plate (31). That is, the extension plate (34) can form a vertical wall between the left boundary surface and the right boundary surface of the exhaust flow path (A).

This extension plate (34) can divide the exhaust path (A) into a first exhaust path (A1) on the right and a second exhaust path (A2) on the left. This extension plate (34) can define the left boundary surface of the first exhaust path (A1) and can define the right boundary surface of the second exhaust path (A2).

The first exhaust path (A1) can form a passage connecting the first outlet (114) and the upper space (10i) in the rear space (10f). The second exhaust path (A2) can form a passage connecting the second intake (214) and the upper space (10i) in the rear space, but can form a passage separate from the first exhaust path (A1).

In addition, the flow path forming member (35) can be separated into a first flow path forming member (35a) and a second flow path forming member (35b). As an example, the first flow path forming member (35a) can be provided in a form in which the first flow path plate (31) and the fastening plate (33) are connected, and the second flow path forming member (35b) can be provided in a form in which the second flow path forming member (35b) and the extension plate (34) are connected.

The first flow path forming member (35a) can be installed inside the cooking appliance through the connection between the fan housing (100) of the rear fan assembly (100) and the fastening plate (33). And the second flow path forming member (35b) can be installed inside the cooking appliance through the connection between the second flow plate (32a) and the lateral support member (41).

As described above, the exhaust path (A) can be divided into a first exhaust path (A1) and a second exhaust path (A2) by the euro-forming member (35), and the air discharged to the rear space (10f) by the rear fan assembly (100) and the air discharged to the rear space (10f) by the corner fan assembly (200) can each flow toward the upper space (10i) through separate paths.

The euro-forming member (35) can prevent the air discharged from the corner fan assembly (200) and the air discharged from the rear fan assembly (100) from mixing inside the exhaust path (A) by forming the exhaust path (A) partitioned in this way.

[Air intake and exhaust structure of the cooking appliance]

FIG. 14 is a rear perspective view showing a first state of a cooking appliance according to a first embodiment of the present invention, and FIG. 15 is a drawing showing an air flow state in the cooking appliance illustrated in FIG. 14. In addition, FIG. 16 is a rear perspective view showing a second state of a cooking appliance according to the first embodiment of the present invention, and FIG. 17 is a drawing showing an air flow state in the cooking appliance illustrated in FIG. 16. In addition, FIG. 18 is a rear perspective view showing a third state of a cooking appliance according to the first embodiment of the present invention, and FIG. 19 is a drawing showing an air flow state in the cooking appliance illustrated in FIG. 18.

Hereinafter, the air intake and discharge structure of the cooking appliance according to the present embodiment will be described with reference to FIGS. 13 to 19.

Referring to FIGS. 13 to 15, an intake port (1) may be provided at the bottom of the cooking appliance, and an exhaust port may be provided at the top of the cooking appliance. The first exhaust port (2) may be arranged on the upper surface of the cabinet (13), but may be arranged so as to be biased toward the rear of the cooking appliance, and the second exhaust port (3) may be arranged so as to be biased toward the front of the cooking appliance. In addition, the third exhaust port (4) may be arranged on the rear of the cooking appliance, but may be arranged on the rear plate (15).

The blower (100, 200) includes a rear fan assembly (100) and a corner fan assembly (200), and the rear fan assembly (100) can be placed in the rear space (10f). And the corner fan assembly (200) can be placed in the rear space (10f) or the corner space (10g, 10h).

When the operation of the rear fan assembly (100) and the corner fan assembly (200) begins, an intake airflow can be formed to suck air from outside the cooking appliance into the inside of the cooking appliance. The intake airflow formed in this manner acts on the outside air through the intake port (1) arranged at the bottom of the cooking appliance. The outside air around the intake port (1), i.e., the cooking gas, can be sucked into the inside of the main body (10) by passing through the intake port (1) by the intake airflow acting in this manner.

And the cooking gas sucked into the main body (10) in this way can flow into the rear space (10f) through the lower space. For example, the cooking gas flowing into the lower space can flow into the rear space (10f) and the corner space (10g, 10h).

The cooking gas introduced into the rear space (10f) can be sucked into the interior of the rear fan assembly (100) through the first suction ports (112) arranged on each side of the rear fan assembly (100). In this way, the cooking gas sucked into the rear fan assembly (100) can be discharged upward through the first discharge port (114) arranged on the upper side of the rear fan assembly (100).

The cooking gas introduced into the corner space (10g, 10h) can be sucked into the interior of the corner fan assembly (200) through the second suction port (212) arranged at the lower side of the corner fan assembly (200). In this way, the cooking gas sucked into the corner fan assembly (200) can be discharged to the side of the corner fan assembly (200) through the second suction port (214) arranged at the side of the corner fan assembly (200).

The rear space (10f) can connect between the intake port (1) arranged on the lower side of the lower space and the upper space (10i). In addition, an exhaust path (A) can be formed in this rear space (10f). The flow of cooking gas discharged from the rear fan assembly (100) and the corner fan assembly (200) can be guided toward the upper space (10i) by the exhaust path (A).

When only the first exhaust port (2) among the exhaust ports (2, 3, 4) is open and the second exhaust port (3) and the third exhaust port (4) are closed (hereinafter referred to as the “first state of the cooking appliance”), the cooking gas flowing upward through the exhaust path (A) can be discharged to the outdoors through the first exhaust port (2).

As an example, the first exhaust port (2) may be connected to a duct (not shown) connected to the outdoors. For example, a duct may be installed on the upper surface of the main body (10), and the interior space of the duct may be connected to the first exhaust port (2).

The first exhaust port (2) connected to the duct in this way can form a passage connecting the upper space (10i) to the outside of the cooking appliance. The first exhaust port (2) can be arranged on the upper side of the upper space (10i), but can be arranged in a position that overlaps the rear space (10f) in the vertical direction.

That is, the rear fan assembly (100), the rear space (10f), and the first exhaust port (2) can be arranged in positions where they overlap in the vertical direction. Preferably, the rear fan assembly (100), the rear space (10f), and the first exhaust port (2) can be arranged in a row along the vertical direction.

In addition, the exhaust path (A) may be arranged between the blower (100, 200) and the first exhaust port (2) in the rear space (10f). The inlet of the exhaust path (A) may be opened toward the blower (100, 200), and the outlet of the exhaust path (A) may be opened toward the upper space (10i). In addition, the first exhaust port (2) may be arranged in an area that overlaps the outlet of the exhaust path (A) in the vertical direction.

Accordingly, the air flow caused by the operation of the rear fan assembly (100) can be made in the same straight direction as the arrangement direction of the rear fan assembly (100), the rear space (10f), and the first exhaust port (2).

As air flows in a straight direction like this, the resistance to air flow is lowered, allowing air to flow more smoothly. Accordingly, the air intake and exhaust performance by the rear fan assembly (100) can be improved, and thus the cooking gas removal performance of the cooking appliance can be improved accordingly.

Meanwhile, the cooking appliance of the present embodiment can also discharge cooking gas sucked into the cooking appliance into the room, as shown in FIGS. 16 and 17. At this time, the cooking appliance may be in a state where only the second exhaust port (3) among the exhaust ports (2, 3, and 4) is open and the first exhaust port (2) and the third exhaust port (4) are closed (hereinafter referred to as “the second state of the cooking appliance”).

In the second state of the cooking appliance, a passage for discharging the cooking gas sucked into the inside of the cooking appliance into the room can be provided by the second exhaust port (3). That is, the cooking gas introduced into the rear space (10f) through the intake port (1) can be discharged into the room through the second exhaust port (3) after passing through the upper space (10i).

As an example, a filter (not shown) may be placed on the bottom of the cooking appliance. The filter is placed in the intake port (1), and cooking gas may pass through the intake port (1) and be filtered by the filter.

As another example, a filter may be placed in the upper space (10i). For example, the filter may be placed inside the main body (10), but may be placed in the second exhaust port (3). In this case, the cooking gas flowing from the rear space (10f) to the upper space (10i) may pass through the filter and be discharged indoors through the second exhaust port (3) in a state of being filtered by the filter.

The cooking appliance of this embodiment can discharge cooking gas sucked into the inside of the cooking appliance to the outside through the third exhaust port (4), as shown in FIGS. 18 and 19.

At this time, the cooking appliance may be in a state where only the third exhaust port (4) among the exhaust ports (2, 3, 4) is open and the first exhaust port (2) and the second exhaust port (3) are closed (hereinafter referred to as “the third state of the cooking appliance”).

As an example, the third exhaust port (4) may be connected to a pipe or duct (not shown) embedded in a wall surface where the cooking appliance is installed. For example, a pipe or duct may be connected to the rear plate (15), and the internal space of the pipe or duct may be connected to the third exhaust port (4).

In this way, the third exhaust port (4) connected to the pipe or duct is positioned closest to the blower (100, 200). Accordingly, in the third state of the cooking appliance, the distance between the blower (100, 200) and the exhaust ports (2, 3, 4) can be made as short as possible. In addition, since the third exhaust port (4) is positioned on the back of the cooking appliance facing the wall, the third exhaust port (4) and the pipe or duct are not exposed to the outside.

That is, in the third state of the cooking appliance, the cooking appliance can reduce the air flow distance inside the cooking appliance, thereby reducing the flow resistance inside the cooking appliance, and the appearance of the cooking appliance can be kept simple and neat.

As described above, the cooking appliance of this embodiment, which adopts a structure in which the blower (100, 200) is arranged in the rear space (10f), allows the air involved in sucking in cooking gas and discharging it through the first exhaust port (2) to flow in a straight direction, thereby minimizing flow loss within the cooking appliance, and thereby providing further improved cooking gas removal performance.

In addition, the cooking appliance of the present embodiment can provide the effect of maintaining a compact size while ensuring that the installation space of the filter is effectively secured in the upper space (10i) and that the filtering and indoor discharge of cooking gas are smoothly performed.

Meanwhile, the space inside the main body (10) can be divided into a side space (10e), a rear space (10f), and an upper space (10i) as described above, and the blower (100, 200) of the present embodiment is placed in the rear space (10f), not in the side space (10e) or the upper space (10i).

Typically, the lateral length of the side space (10e) where the main chamber is not arranged is set shorter than the front-rear length of the rear space (10f). In other words, the side space (10e) can only provide a narrower space than the rear space (10f).

In the rear space (10f), various devices may be placed depending on the type of cooking appliance. For example, in the case of a cooking appliance providing a convection function, a convection module may be placed in the rear space (10f).

In comparison, in the side space (10e) that does not form the main chamber (10b, 10c, 10d), it is very rare for a separate device to be placed. Therefore, the lateral width of the side space (10e) does not need to be increased unnecessarily. If the lateral length of the side space (10e) is increased unnecessarily, only the overall size of the cooking appliance increases regardless of whether the performance of the cooking appliance is improved.

Considering these points, it is desirable that the side space (10e) be formed to provide a narrower space compared to the rear space (10f).

To reduce costs, it is common for cooking appliances with the same cooking chamber volume to share a body (10) of the same specifications. For example, a cooking appliance that provides both a high-frequency function and a convection function can be manufactured using a body (10) of the same specifications as a cooking appliance that provides only a high-frequency function.

Accordingly, the main body (10) of the present embodiment may include a rear space (10f) that provides a space suitable for arranging a convection module, and the side space (10e) may be formed in a form that provides only a narrow space compared to the rear space (10f).

Considering these points, the blower (100, 200) of the present embodiment may be placed in the rear space (10f) which provides more sufficient space than the side space (10e). By placing the blower (100, 200) in the rear space (10f) in this way, not only can the flow loss inside the cooking appliance be reduced as described above, but also a larger and higher-performance fan assembly can be applied to the blower (100, 200).

That is, the cooking appliance of the present embodiment including the blower (100, 200) arranged in the rear space (10f) can provide further improved cooking gas removal performance while suppressing an increase in the size of the cooking appliance by using a main body (10) of a standard that is commonly used.

[Lack of support]

Fig. 20 is an enlarged view of the corner pan assembly and its surroundings, and Fig. 21 is a rear perspective view showing the support member shown in Fig. 20 in isolation. Also, Fig. 22 is a rear perspective view showing a portion of a cooking appliance to which another example of the support member is applied, and Fig. 23 is a rear perspective view showing the support member shown in Fig. 22 in isolation.

Referring to FIG. 6 and FIG. 20 and FIG. 21, the cooking appliance of the present embodiment may include a support member (40). The support member (40) may support the corner fan assembly (200) so that the flow of air discharged from the second suction port (214) may be guided toward the rear space (10f).

At least a portion of the support member (40) can form a wall that blocks the space between the side space (10e) and the rear space (10f). That is, at least a portion of the support member (40) can form a wall that blocks the space between the corner fan assembly (200) and the rear fan assembly (100) in the rear space (10f).

The support member (40) can form a wall that divides the rear space (10f) into two regions along the lateral direction. As an example, the support member (40) can divide a part of the rear space (10f) adjacent to the side space (10e) into a corner space (10g, 10h). In addition, at least a part of the support member (40) can form a wall that covers the corner fan assembly (200) from the side. This wall can be formed by the lateral support member (41).

The second suction port (214) may be arranged on the side of the corner fan assembly (200) toward the support member (40), more specifically, the lateral support member (41). In addition, a discharge hole (41a) may be formed in the lateral support member (41). The discharge hole (41a) may be formed to expose the second suction port (214) laterally, and may be formed to penetrate the lateral support member (41) laterally.

The lateral support member (41) can be combined with the corner fan assembly (200). That is, the corner fan assembly (200) can be combined laterally with the lateral support member (41) and supported by the support member (40).

The support member (40) may include a front support portion (42). The front support portion (42) forms the front surface of the support member (40) and may be arranged on the front side of the corner fan assembly (200).

The front support member (42) can form a vertical wall covering the corner fan assembly (200) from the front. For example, the front support member (42) can form a vertical plane perpendicular to the front-back axis. The front support member (42) can be arranged between the cooling fan (6; see FIG. 25) to be described later and the corner fan assembly (200), and can form a wall blocking the cooling fan (6) and the corner fan assembly (200) in the front chamber (10b, 10c, 10d).

The front support member (42) can be connected to the lateral support member (41) on the lateral side of the lateral support member (41). As an example, the right end of the front support member (42) can be connected to the front end of the lateral support member (41). For example, the front support member (42) and the lateral support member (41) can be connected in an “L” shape.

The front support member (42) connected to the lateral support member (41) in this way can support the lateral support member (41) from the front side. The front support member (42) can simultaneously serve as a shield wall that blocks the cooling fan (6) and the corner fan assembly (200), and as a support wall that supports the lateral support member (41) that supports the corner fan assembly (200).

In addition, the front support member (42) may include a support surface that forms a vertical plane for coupling with electrical components. For example, electrical components such as a magnetron, a high-voltage transformer, a high-voltage condenser, a noise filter, etc. may be placed in the electrical compartment (10b, 10c, 10d), and at least one of the electrical components may be installed on the support surface of the front support member (42). In this embodiment, it is exemplified that a high-voltage condenser is installed on the support surface of the front support member (42).

In addition, the support member (40) may further include an upper support member (43). The upper support member (43) forms the upper surface of the support member (40) and may be arranged on the upper side of the corner fan assembly (200). As an example, the upper support member (43) may be arranged in the corner space portion (10g, 10h).

The upper support member (43) is arranged above the lateral support member (41) and the front support member (42), and can be vertically connected to at least one of the lateral support member (41) and the front support member (42). In this embodiment, the upper support member (43) is exemplified as being connected to both the lateral support member (41) and the front support member (42).

As an example, the front end of the upper support member (43) can be connected to the upper end of the front support member (42), and the right end of the upper support member (43) can be connected to the upper end of the lateral support member (41). By the upper support member (43), the three sides of the support member (40) are connected as one, and thus the structural stability of the support member (40) can be improved.

Additionally, the upper support member (43) may include a support surface that forms a horizontal plane for joining with the electric component. In this embodiment, a noise filter connected to the corner fan assembly is exemplified as being installed on the support surface of the upper support member (43).

The support member (40) including the lateral support member (41), the front support member (42) and the upper support member (43) as described above not only provides a shielding wall between the cooling fan (6) and the corner fan assembly (200), but can also provide a support wall for stable installation of the electric component and the corner fan assembly (200).

As an example, the support member (40) may be provided in a form in which the lateral support member (41), the front support member (42), and the upper support member (43) are formed integrally. Such a support member (40) can facilitate the assembly and installation of the support member (40) and the management of parts, and can have excellent structural stability.

As another example, as shown in FIGS. 22 and 23, the lateral support portion, the front support portion, and the upper support portion may be provided separately.

According to this, the support member (45) may include a first support plate (45a), a second support plate (45b), and a third support plate (45c), and the first support plate (45a), the second support plate (45b), and the third support plate (45c) may each be provided as separate parts.

For example, the first support plate (45a) can form a lateral support portion, the second support plate (45b) can form a front support portion, and the third support plate (45c) can form an upper support portion. In this way, the first support plate (45a), the second support plate (45b), and the third support plate (45c) provided separately can be combined with each other to form a support member (40).

As an example, the first support plate (45a) may be provided in a form that includes both the lateral support portion and the connecting passage forming member (37, 38). That is, in the first support plate (45a), the lateral support portion and the connecting passage forming member (37, 38) may be formed integrally.

Additionally, the through hole (41b) may be provided in the first support plate (45a) or in the third support plate (45c).

[Structure of the battle room]

Fig. 24 is a drawing showing a state in which outside air is introduced into a battle room through a cold air inlet, Figs. 25 to 27 are drawings showing a state of air flow introduced into a battle room, and Fig. 28 is a drawing showing a state of air flow introduced into a lower corner space through a connecting passage from an upper corner space.

Referring to FIGS. 24 and 25, a cold air inlet (5) may be provided in the main body (10). The cold air inlet (5) may be arranged on the upper surface of the main body (10) together with the first exhaust port (2) and the second exhaust port (3).

As an example, the cold air inlet (5) may be formed to penetrate vertically through the upper surface of the cabinet (13). This cold air inlet (5) may be arranged on the upper side of the electrical compartment (10b, 10c, 10d) and may open the electrical compartment (10b, 10c, 10d) to the outside of the main body (10). Outside air may be introduced into the electrical compartment (10b, 10c, 10d) through the cold air inlet (5).

Referring to FIGS. 25 and 26, the cooking appliance of the present embodiment may include a partition plate (50). The partition plate (50) may be placed in a side space (10e), more specifically, in a main chamber (10b, 10c, 10d).

As an example, the partition plate (50) can form a horizontal plane perpendicular to the vertical axis. This partition plate (50) partitions the side space (10e) upward and downward, and can partition it into a lower electrical room (10b) and an upper electrical room (10c). For example, the electrical rooms (10b, 10c, 10d) can be partitioned into a lower electrical room (10b) below the partition plate (50) and an upper electrical room (10c) above the partition plate (50).

As an example, the lower electrical room (10b) may occupy a much wider space than the upper electrical room (10c) within the electrical room (10b, 10c, 10d). For example, the vertical length of the lower electrical room (10b) may be set to be much longer than the vertical length of the upper electrical room (10c). Most electrical components, including a magnetron, a high-voltage transformer, a high-voltage condenser, etc., may be placed primarily in the lower electrical room (10b).

The cooking appliance of the present embodiment may further include a cooling fan (6). The cooling fan (6) is provided to allow external air to be introduced into the electrical compartment (10b, 10c, 10d) through the cold air inlet (5). As an example, the cooling fan (6) may be placed in the lower electrical compartment (10b) together with most of the electrical components.

The blower (100, 200) is arranged at the rear side of the cooling fan (6), and a support member (40), more specifically a front support member (42), can be arranged between the cooling fan (6) and the corner fan assembly (200).

The cooling fan (6) can generate airflow to draw outside air into the interior of the main body (10) through the cold air inlet (5).

When the cooling fan (6) is in operation, outside air can flow into the upper electrical compartment (10c) through the cold air inlet (5). The air that flows into the upper electrical compartment (10c) can flow into the lower electrical compartment (10b) through the partition plate (50).

For this purpose, a passage hole (52, 54) may be provided in the partition plate (50). The passage hole (52, 54) may form a passage connecting the upper electrical chamber (10c) and the lower electrical chamber (10b) in the partition plate (50). As an example, the passage hole (52, 54) may be formed to penetrate the partition plate (50) in the vertical direction.

Air introduced into the upper electrical compartment (10c) through the cold air inlet (5) can be introduced into the lower electrical compartment (10b) through the passage holes (52, 54). In this way, air introduced into the electrical compartments (10b, 10c, 10d) can cool electrical components placed in the lower electrical compartment (10b).

In addition, some of the air that flows into the lower chamber (10b) may flow into the cooking chamber (10a; see Fig. 2). For this purpose, a side hole (11a) may be provided in the cavity (11). The side hole (11a) may form a passage connecting at least one of the lower chamber (10b) and the upper chamber (10c) and the cooking chamber (10a).

In this embodiment, it is exemplified that the side hole (11a) is arranged in the lower chamber (10b). As an example, the side hole (11a) is formed to penetrate laterally in the cavity (11), and a passage connecting the lower chamber (10b) and the cooking chamber (10a) can be formed in the cavity (11). This side hole (11a) can be arranged on the front side of the support member (40).

The cooking appliance of the present embodiment may further include a blocking plate (55). The blocking plate (55) may partition the upper chamber (10c) front and rear so that the front area of the upper chamber (10c) is separated into an intake chamber (10d).

As an example, the blocking plate (55) can form a vertical wall surface that is orthogonal to the forward-backward axis. This blocking plate (55) is arranged on the upper side of the partition plate (50) and can be joined to the upper surface of the partition plate (50).

By means of the blocking plate (55) provided in this manner, the area between the front plate (12) and the blocking plate (55) in the upper electrical compartment (10c) can be partitioned into an intake chamber (10d).

A plurality of passage holes (52, 54) may be provided in the partition plate (50). As an example, a first passage hole (52) and a second passage hole (54) may be provided in the partition plate (50). The first passage hole (52) and the second passage hole (54) may be arranged to be spaced apart in the front-back direction with a blocking plate (55) interposed therebetween.

The first passage hole (52) can form a passage connecting the intake chamber (10d) and the lower electrical chamber (10b). This first passage hole (52) can be arranged in front of the blocking plate (55) and the cooling fan (6), and can be formed to penetrate the partition plate (50) in the vertical direction.

The second passage hole (54) can form a passage connecting the upper body chamber (10c) and the lower body chamber (10b) at the rear side of the intake chamber (10d). This first passage hole (52) can be arranged at the rear side of the blocking plate (55) and the cooling fan (6), and can be formed to penetrate the partition plate (50) in the vertical direction.

According to the present embodiment, an upper support member (43) may be arranged on the rear side of the partition plate (50). The upper support member (43) may be arranged in the corner space portion (10g, 10h) and may partition the corner space portion (10g, 10h) upwardly and downwardly. By the upper support member (43), the corner space portion (10g, 10h) may be partitioned into an upper corner space portion (10g) and a lower corner space portion (10h).

The lower corner space (10h) may be arranged below the upper support portion (43). The upper boundary surface of the lower corner space (10h) may be defined by the upper support portion (43), the front boundary surface of the lower corner space (10h) may be defined by the front support portion (42), and the right boundary surface of the lower corner space (10h) may be defined by the lateral support portion (41). The corner fan assembly (200) may be arranged in the lower corner space (10h).

The upper corner space (10g) can be arranged on the upper side of the upper support member (43). The upper corner space (10g) is arranged on the rear side of the rear side of the upper electrical room (10c), and can be connected to the upper electrical room (10c) at the rear side of the upper electrical room (10c).

At least one of the electrical components arranged in the upper electrical room (10c) may be arranged in the upper support member (43). As an example, a noise filter connected to the corner fan assembly (200) may be arranged in the upper corner space (10g), and this noise filter may be installed on the upper surface of the upper support member (43).

The air introduced into the lower electrical compartment (10b) by the cooling fan (6) can flow into the upper electrical compartment (10c) through the second passage hole (54). In this way, the air introduced into the upper electrical compartment (10c) can cool the electrical components installed in the upper support member (43) by passing through the upper corner space (10g).

Meanwhile, the upper electrical compartment (10c) and the lower electrical compartment (10b) can be connected by a connecting passage (39). The connecting passage (39) can form a passage for air introduced into the lower electrical compartment (10b) by the cooling fan (6) to flow through the upper electrical compartment (10c) to the blower (100, 200). For example, the connecting passage (39) can form a passage for air introduced into the electrical compartments (10b, 10c, 10d) to flow through the upper corner space (10g) to the corner fan assembly (200).

In addition, a through hole (41b) may be provided in the lateral support member (41). The through hole (41b) is provided so that the space surrounded by the lateral support member (41) and the front support member (42), i.e., the lower corner space (10h), can be opened laterally.

The connecting passage (39) can form a passage connecting the through hole (41b) and the upper electrical room (10c), more specifically, the through hole (41b) and the upper corner space (10g). The connecting passage (39) can be connected to the upper corner space (10g) and the lower corner space (10h) on the side of the upper corner space (10g, 10h), respectively. The connecting passage (39) and the lower corner space (10h) can be connected through the through hole (41b).

As described above, the connecting channel portion (39) can be formed by the connecting channel forming member (37, 38). In the connecting channel forming member (37, 38), the first compartment portion (37) can form a vertical wall that is arranged at a predetermined interval on the side of the lateral support portion (41). In addition, the second compartment portion (38) can form a wall that is connected to the lateral support portion (41) at the lower side of the through hole (41b) and connects the lateral support portion (41) and the first compartment portion (37).

The two sides of the connecting channel (39) can be defined by the lateral support (41) and the first partition (37). For example, the left side of the connecting channel (39) can be defined by the lateral support (41), and the right side of the connecting channel (39) can be defined by the first partition (37). The bottom of the connecting channel (39) can be defined by the second partition (38).

Air introduced into the upper chamber (10c) can pass through the upper corner space (10g) and be introduced into the connecting passage (39). Air introduced into the connecting passage (39) can be introduced into the lower corner space (10h) through the through hole (41b) and then be sucked into the corner fan assembly (200).

The suction force of the corner fan assembly (200) can be applied to the lower corner space (10h). The suction force applied to the lower corner space (10h) can also affect the connecting passage (39) connected to the lower corner space (10h) and the upper corner space (10g). In other words, the suction force of the corner fan assembly (200) can affect the upper corner space (10g), and this can act as a force that causes the air flowing into the upper corner space (10g) to flow toward the lower corner space (10h).

Ultimately, the suction force of the corner fan assembly (200) can act as a force to guide the air flow from the lower chamber (10b) to the upper chamber (10c) through the connecting passage (39) to the lower corner space (10h).

Below, we will examine the air flow in the battle rooms (10b, 10c, 10d).

Outside air can be introduced into the interior of the main body (10) through the cold air inlet (5), as shown in Fig. 24. Air passing through the cold air inlet (5) in this way can be introduced into the intake chamber (10d), as shown in Figs. 25 to 27.

Air introduced into the intake chamber (10d) can flow into the lower electrical compartment (10b) by passing through the first passage hole (52) and the partition plate (50). In the lower electrical compartment (10b), air can flow rearward by the cooling fan (6). In this way, air flowing rearward in the lower electrical compartment (10b) can cool electrical components placed in the lower electrical compartment (10b).

Some of the air flowing in the lower chamber (10b) can pass through the cavity (11) via the intake port (1) and flow into the chamber. Other some of the air flowing in the lower chamber (10b) can pass through the partition plate (50) via the second passage hole (54) and flow into the upper chamber (10c).

In the upper electrical compartment (10c), air can flow toward the connecting passage (39) under the influence of the suction force of the corner fan assembly (200). For example, air introduced into the upper electrical compartment (10c) can pass through the upper corner space (10g) and cool the electrical components, and then, as illustrated in Fig. 28, can be introduced into the connecting passage (39).

The air flowing into the connecting passage (39) can pass through the lateral support portion (41) via the through hole (41b) and then flow into the lower corner space portion (10h) and then be sucked into the corner fan assembly (200). That is, the air flowing into the lower corner space portion (10h) from the connecting passage portion (39) can be combined with the air flowing into the main body (10) through the intake port (1), as illustrated in FIG. 13, and then be sucked into the corner fan assembly (200) and then discharged into the exhaust passage (A).

As illustrated in FIGS. 24 to 28, the flow path formed in the electrical compartment (10b, 10c, 10d), the corner space portion (10g, 10h), and the connecting flow path portion (39) allows the force provided by the suction force of the corner fan assembly (200) to be added to the force provided by the cooling fan (6) in the electrical compartment (10b, 10c, 10d), thereby enabling the air to flow more smoothly within the electrical compartment (10b, 10c, 10d) and contributing to enabling the cooling of electrical components placed in the electrical compartment (10b, 10c, 10d) to be more effective.

In addition, as described above, the air path formed in the main body room (10b, 10c, 10d), the corner space part (10g, 10h), and the connecting air path part (39) can contribute to increasing the air intake of the corner fan assembly (200) by allowing the air introduced into the main body room (10b, 10c, 10d) to flow toward the corner fan assembly (200), and ultimately to effectively increasing the discharge air volume of the corner fan assembly (200).

Meanwhile, referring to FIGS. 25 to 27, the cooking appliance of the present embodiment may further include a euro partition plate (16). The euro partition plate (16) is provided so as to partition the space above the cavity (11) and the partition plate (50). This euro partition plate (16) may partition the space above the cavity (11) and the partition plate (50) into an upper electrical chamber (10c) and an upper space portion (10i).

As an example, the euro partition plate (16) can form a vertical wall perpendicular to the lateral axis. This euro partition plate (16) can block the upper electrical chamber (10c) and the upper space (10i) and separate these two spaces. For example, the euro partition plate (16) can define the right boundary surface of the upper electrical chamber (10c) and the left boundary surface of the upper space (10i).

In addition, the cooking appliance of the present embodiment may include a waveguide (17). The waveguide (17) is provided to transmit microwaves generated from a magnetron installed in a power chamber (10b, 10c, 10d) to a cooking chamber (10a).

The waveguide (17) is arranged in the upper electrical room (10c) and the upper space (10i), and can be installed on the upper surface of the partition plate (50) and the cavity (11). That is, a part of the waveguide (17) is installed on the upper surface of the partition plate (50), and the remaining part of the waveguide (17) can be installed on the upper surface of the cavity (11) by laterally penetrating the passage partition plate (16).

A space is formed inside the waveguide (17), and the inlet of the waveguide (17) connected to this space can be connected to a magnetron, and the outlet of the waveguide (17) connected to this space can be connected to a cooking chamber (10a). Microwaves introduced into the interior of the waveguide (17) through the inlet of the waveguide (17) can be introduced into the cooking chamber (10a) through the outlet of the waveguide (17).

The exit of the waveguide (17) can be connected to the cooking chamber (10a) from the upper surface of the cavity (11). Accordingly, microwaves transmitted from the magnetron through the waveguide (17) can be introduced into the cooking chamber (10a) from the upper side of the cooking chamber (10a) through the upper surface of the cavity (11). As an example, the exit of the waveguide (17) can be arranged at the upper side of the cavity (11), but can be arranged approximately at the lateral center of the cavity (11).

If the vertical length of the cooking appliance is shortened, the vertical length of the cooking chamber (10a) is also likely to be shortened. Even if the blower (100, 200) is arranged in the rear space (10f) instead of the upper space (10i), and the vertical length of the upper space (10i) may be reduced accordingly, the reduction in the length of the upper space (10i) cannot but be smaller than the reduction in the length of the entire cooking appliance, so it is difficult to avoid a reduction in the length of the cooking chamber (10a) due to the reduction in the length of the cooking appliance.

In this case, the shape of the cooking chamber (10a) is flat in the horizontal direction compared to the cooking chamber of a conventional cooking appliance. In a cooking appliance having a cooking chamber (10a) of this shape, when microwaves are introduced into the cooking chamber (10a) through the side of the cavity (11), it is difficult for the microwaves to be supplied evenly throughout the cooking chamber (10a).

Considering these points, in the present embodiment, a waveguide (17) is installed on the upper surface of the cavity (11), and microwaves can be introduced into the cooking chamber (10a) through the upper surface of the cavity (11). That is, in the cooking appliance of the present embodiment, microwaves can be supplied through the upper side of the cooking chamber (10a), and thus, microwaves can be evenly supplied to the entire cooking chamber (10a).

[Example of absence of cover]

Referring to FIGS. 25 to 27, the cooking appliance of the present embodiment may include a covering member (60). The covering member (60) is provided so as to cover the passage holes (52, 54) formed in the partition plate (50), more specifically, the first passage hole (52), from the upper or lower side. This covering member (60) may be arranged to be spaced apart from the partition plate (50) or the first passage hole (52) in the upper and lower direction by a predetermined distance.

In this embodiment, it is exemplified that the covering member (60) is arranged on the upper side of the partition plate (50) and the first passage hole (52). This covering member (60) may be arranged between the upper surface of the cabinet (13) and the partition plate (50). As an example, the covering member (60) may be arranged in the upper electrical chamber (10c), more specifically, in the intake chamber (10d).

In the vertical direction, the covering member (60) can be placed between the first passage hole (52) and the cold air inlet (5). This covering member (60) can be arranged so that when viewed from the upper side of the main body (10), either the first passage hole (52) or the cold air inlet (5) is completely covered by the covering member (60).

As an example, the covering member (60) may be provided so that the first passage hole (52) is completely covered by the covering member (60). For example, the covering member (60) may form a horizontal wall that completely covers the first passage hole (52) from the upper side.

The above-mentioned covering member (60) can be installed on the blocking plate (55). This covering member (60) is coupled to the front of the blocking plate (55) and can be installed on the blocking plate (55) in a form that protrudes forward from the blocking plate (55). At this time, the covering member (60) can be coupled to the blocking plate (55) at a position spaced upward by a predetermined distance from the upper surface of the partition plate (50).

By means of this covering member (60), the first passage hole (52) is completely covered so that it cannot be seen from above, but air can flow smoothly through the first passage hole (52). That is, the covering member (60) covers the first passage hole (52) so that the first passage hole (52) cannot be seen from above the covering member (60), but air in the intake chamber (10d) can smoothly flow into the lower body chamber (10b) through the first passage hole (52) regardless of the presence of the covering member (60).

The covering member (60) provided as described above can block the space between the first passage hole (52) and the cold air inlet (5). This covering member (60) can serve to cover the flames rising to the upper side of the first passage hole (52) between the first passage hole (52) and the cold air inlet (5) so that the flames generated in the lower electrical compartment (10b) are not exposed to the outside of the cooking appliance through the cold air inlet (5).

High-voltage electrical components, such as high-voltage transformers and high-voltage condensers, are mostly placed in the lower electrical room (10b). As such, there is a risk that high-voltage electrical components placed in the lower electrical room (10b) may cause a fire in the lower electrical room (10b).

If a fire breaks out in the lower chamber (10b) and the resulting flames are exposed to the outside of the cooking appliance, there is a high risk that the fire will spread as the flames exposed to the outside of the cooking appliance spread to the surrounding areas of the cooking appliance.

In the cooking appliance, a first passage hole (52) is arranged on the upper side of the lower chamber (10b) to form a passage necessary for air from the intake chamber (10d) to flow into the lower chamber (10b). In addition, a cold air inlet (5) is arranged on the upper side of the first passage hole (52) to form a passage necessary for outside air to flow into the intake chamber (10d).

Accordingly, the flame generated in the lower chamber (10b) may rise into the intake port (1) through the first passage hole (52) and may rise to the upper side of the main body (10) through the cold air inlet (5) in the intake chamber (10d) and be exposed to the outside of the cooking appliance. To prevent this, it is necessary to block the flame inside the cooking appliance so that the flame generated in the lower chamber (10b) is not exposed to the outside of the cooking appliance.

Considering these points, in this embodiment, a covering member (60) arranged in the intake chamber (10d) is provided to block the space between the first passage hole (52) and the cold air inlet (5). This covering member (60) can prevent the flame generated in the lower electrical chamber (10b) from being exposed to the outside of the cooking appliance by blocking the flame generated in the lower electrical chamber (10b) from being emitted from the intake chamber (10d).

The cooking appliance of this embodiment, which is equipped with the covering member (60) as described above, can provide the effect of significantly reducing the risk of fire spreading due to flames generated inside the cooking appliance while allowing air to flow smoothly into the lower electrical compartment (10b).

[Other examples of absence of cover]

FIG. 29 is a rear perspective view illustrating a portion of a cooking appliance to which another example of a covering member is applied.

As shown in Fig. 29, a blocking plate (60; see Fig. 27) is not arranged in the upper electrical room (10c), and accordingly, the upper electrical room (10c) may not be partitioned front-back. The covering member (65) arranged in the upper electrical room (10c) may be provided in a form that is directly cut into the partition plate (50). As an example, the covering member (65) may be formed in a hexahedral shape including a horizontal surface portion (66) and a vertical surface portion (67).

The transverse surface (66) forms the upper surface of the covering member (65) and is provided to cover the first passage hole (52) from the upper side. As an example, the transverse surface (66) can form a transverse plane perpendicular to the vertical axis.

The covering member (65) may further include a vertical surface portion (67). The vertical surface portion (67) forms a side surface of the covering member (65) and may be arranged between the horizontal surface portion (66) and the partition plate (50). The vertical surface portion (67) may be coupled to the upper surface of the partition plate (50) while spacing the horizontal surface portion (66) upward from the upper surface of the partition plate (50).

The covering member (65) may include a plurality of vertical surfaces (67) that surround the first passage hole (52) from the side. A space surrounding the first passage hole (52) may be formed inside the covering member (65) including the plurality of vertical surfaces (67).

A ventilation hole (67a) may be provided in at least one of the plurality of vertical surfaces (67). In the present embodiment, it is exemplified that a ventilation hole (67a) is provided in each of the vertical surfaces (67).

The ventilation hole (67a) may be formed to penetrate horizontally in the vertical surface portion (67). This ventilation hole (67a) may form a passage connecting the outside of the shielding member (65) and the inside of the shielding member (65). Air introduced into the upper electrical compartment (10c) through the cold air inlet (5; see FIG. 24) may be introduced into the inside of the shielding member (65) through the ventilation hole (67a) from the outside of the shielding member (65), and then introduced into the lower electrical compartment (10b) through the first passage hole (52).

The covering member (65) provided as described above can provide the effect of significantly reducing the risk of fire spreading due to flames generated inside the cooking appliance, and can be effectively installed in the upper electrical compartment (10c) even when the blocking plate (55) is not installed.

Fig. 30 is a rear perspective view showing the intake and exhaust states of the cooking appliance according to the first embodiment of the present invention, and Fig. 31 is a rear perspective view showing the air flow state inside the cooking appliance shown in Fig. 30. In addition, Fig. 32 is a plan view showing an enlarged view of the area around the common exhaust port shown in Fig. 30, and Fig. 33 is an enlarged view showing an exhaust duct and its area.

Referring to FIG. 14, FIG. 30, and FIG. 32, a circulation air outlet (11b: see FIG. 34) may be provided inside the main body (10). The circulation air outlet (11b) may form a passage connecting the cooking chamber (10a) and the upper space (10i) on the upper surface of the cavity (11). As an example, the circulation air outlet (11b) may be formed to penetrate vertically on the upper surface of the cavity (11).

According to the present embodiment, a plurality of second exhaust ports (3) may be arranged at the upper portion of the main body (10). At least one of the plurality of second exhaust ports (3) may be provided as a common exhaust port (3a). The common exhaust port (3a) is provided so that air flowing into the upper space (10i) by the blower (100, 200) and air flowing into the upper space (10i) through the circulating air discharge port (11b) can be discharged together.

As an example, the circulating air outlet (11b) may be arranged at a position shifted to the right from the lateral center of the cavity (11). For example, the circulating air outlet (11b) may be arranged at a position overlapping at least a portion of the common exhaust port (3a) in the front-back direction.

According to the present embodiment, a plurality of second exhaust ports (3) and cold air inlets (5) can be arranged laterally. As an example, at least one of the plurality of second exhaust ports (3) arranged at a position furthest from the cold air inlet (5) can be provided as a common exhaust port (3a). For example, the cold air inlet (5) can be arranged on the left side of the second exhaust port (3), and one of the plurality of second exhaust ports (3) arranged at the rightmost side can be provided as a common exhaust port (3a).

As another example, at least one of the plurality of second exhaust ports (3) arranged laterally and located at the furthest position from the main chamber (10b, 10c, 10d) may be provided as a common exhaust port (3a).

As another example, at least one of the plurality of second exhaust ports (3) laterally distributed and arranged at a position closest to the expansion plate (18) may be provided as a common exhaust port (3a). At this time, at least a portion of the common exhaust port (3a) may be arranged to overlap the expansion plate (18) in the vertical direction.

In addition, an exhaust duct (70) may be arranged in the upper space (10i). The exhaust duct (70) is provided so as to guide the flow of air discharged from the cooking chamber (10a) to the circulating air outlet (11b) toward the common exhaust port (3a).

In this embodiment, the circulating air outlet (11b) may be positioned at a position that is offset to the rear from the center in the front-back direction of the cavity (11). For example, the circulating air outlet (11b) may be positioned on the upper surface of the cavity (11), but may be positioned adjacent to the rear right corner of the cavity (11).

The exhaust duct (70) is provided so as to guide the air flow discharged through the circulating air outlet (11b) located at this location toward the common exhaust port (3a) located at a location adjacent to the front of the main body (10).

In addition, the cooking appliance of the present embodiment may include an expansion plate (18). The expansion plate (18) may partition the side space (10e) such that a portion of the side space (10e) is separated into an expansion upper space (10j). By the expansion plate (18), an upper portion of the expansion plate (18) among the side space (10e) may be partitioned into an expansion upper space (10j).

[Expansion Plate]

Referring to FIG. 14, FIG. 30, and FIG. 33, at least a portion of the expansion plate (18) may be placed in the side space (10e). In the present embodiment, it is exemplified that the expansion plate (18) is placed in the side space (10e) rather than in the main chamber (10b, 10c, 10d) among a pair of side spaces (10e) placed inside the cooking appliance.

As an example, the expansion plate (18) can form a horizontal plane orthogonal to the vertical axis. For example, the expansion plate (18) can form a plane parallel to the upper surface of the cavity (11).

Preferably, the upper surface of the expansion plate (18) and the upper surface of the cavity (11) can form the same plane. The upper surface of the cavity (11) can define the bottom surface of the upper space (10i), and the upper surface of the expansion plate (18) can define the bottom surface of the expanded upper space (10j). Accordingly, the bottom surface of the upper space (10i) and the bottom surface of the expanded upper space (10j) can be arranged on the same plane.

The expanded upper space (10j) provided as described above can be connected to the upper space (10i) from the upper side of the side space (10e). That is, the expanded upper space (10j) is arranged above the side space (10e) and on the lateral side of the upper space (10i), and can be connected laterally to the upper space (10i).

According to the present embodiment, the upper space (10i) and the expanded upper space (10j) are connected as one on the upper side of the cavity (11), and accordingly, an exhaust space (10i, 10j) can be formed on the upper side of the cavity (11) and the side space (10e). In the present embodiment, the exhaust space (10i, 10j) can be defined as a space in which the upper space (10i) and the expanded upper space (10j) are connected as one on the upper side of the cavity (11) and the expanded plate (18).

In this way, the exhaust space (10i, 10j) formed on the upper side of the cavity (11) and the expansion plate (18) can be communicated with the exhaust ports (2, 3, 4) arranged on the upper surface of the main body (10). The exhaust ports (2, 3, 4) can open the space where the upper space (10i) and the expanded upper space (10j) are connected, i.e., the exhaust space (10i, 10j), to the outside of the main body (10).

The side space (10e) and the rear space (10f) can be connected to the lower space. The side space (10e) and the rear space (10f) can be connected to the lower space in the vertical direction or in the lateral direction. The intake port (1) is connected to the lower space, and can be connected to the intake port (1) through the lower space of the side space (10e) and the rear space (10f).

A part of the expansion plate (18) may be placed in the rear space (10f). Accordingly, a part (18a; hereinafter referred to as “side compartment of the expansion plate”) of the expansion plate (18) may be placed in the side space (10e), and another part (18b; hereinafter referred to as “rear compartment of the expansion plate”) of the expansion plate (18) may be placed in the rear space (10f).

As described above, the side partition (18a) of the expansion plate (18) can partition the side space (10e) so that a part of the side space (10e) is separated into an expanded upper space (10j). And, the rear partition (18b) of the expansion plate (18) can partition a part of the rear space (10f) so that a part of the rear space (10f) is separated into an expanded upper space (10j).

That is, the expansion plate (18) can partition a portion of the rear space (10f) and the side space (10e) so that a portion of the side space (10e) and the rear space (10f) are separated into an expanded upper space (10j).

The expansion plate (18) may be provided with a first coupling portion (18c). The first coupling portion (18c) may be provided for coupling between the expansion plate (18) and the cavity (11). As an example, the first coupling portion (18c) may be formed to protrude horizontally from at least one of the side compartment portion (18a) and the rear compartment portion (18b). This first coupling portion (18c) may face the upper surface of the cavity (11) in the vertical direction and may be coupled with the cavity (11).

The connection between the first joint (18c) and the cavity (11) may be made by a joining method such as welding, or by a fastening method such as a screw.

In this embodiment, the first coupling portion (18c) is exemplified as being formed to protrude laterally from the side compartment portion (18a). As another example, the first coupling portion (18c) may be formed to protrude forwardly from the rear compartment portion (18b). As another example, the first coupling portion (18c) may protrude vertically from at least one of the side compartment portion (18a) and the rear compartment portion (18b) and be coupled with the side surface of the cavity (11).

In addition, the expansion plate (18) may include at least one of a second coupling portion (18d) and a third coupling portion (18e). The second coupling portion (18d) and the third coupling portion (18e) may be provided for coupling between the expansion plate (18) and the cabinet (13).

The second coupling portion (18d) may be provided in a form that protrudes from the side partition portion (18a) or the first coupling portion (18c). In this embodiment, the first coupling portion (18c) is exemplified as protruding horizontally from the side partition portion (18a), and the second coupling portion (18d) is exemplified as protruding vertically from the first coupling portion (18c).

As an example, the second joint (18d) may form a vertical wall orthogonal to the lateral axis. A plane parallel to the upper surface of the cabinet (13) may be formed at the upper end of the second joint (18d).

The third connecting portion (18e) may be provided in a protruding form from the rear compartment (18b). As an example, the third connecting portion (18e) may form a vertical wall perpendicular to the front-back axis. A plane parallel to the upper surface of the cabinet (13) may be formed at the upper end of the third connecting portion (18e).

The vertical lengths of the second coupling portion (18d) and the third coupling portion can be set to lengths corresponding to the distance between the expansion plate (18) and the cabinet (13), respectively. The second coupling portion (18d) and the third coupling portion (18e) formed in this manner can be coupled to the cabinet (13) at the lower side of the cabinet (13).

By the connection between the second coupling portion (18d) and the cabinet (13) and the connection between the third coupling portion (18e) and the cabinet (13), the expansion plate (18) can support the cabinet (13) so that the upper surface of the cabinet (13) does not sag downward. In addition, the expansion plate (18) can be stably fixed inside the cooking appliance by being connected to various structures at various locations using the first coupling portion (18c), the second coupling portion (18d), and the third coupling portion (18e).

As an example, the second connecting portion (18d) may be arranged between the upper space portion (10i) and the expanded upper space portion (10j). That is, the second connecting portion (18d) may be arranged in the exhaust space (10i, 10j) in the form of a vertical wall that laterally blocks a portion between the upper space portion (10i) and the expanded upper space portion (10j).

A plurality of ventilation holes may be provided in this second joint portion (18d). Each ventilation hole may be formed to penetrate laterally through the second joint portion (18d), and the ventilation holes may be arranged in most areas of the second joint portion (18d).

The second joint (18d) having a plurality of ventilation holes in this way can provide a structure for joining the expansion plate (18) and the cabinet (13), while minimizing interference with the flow of air within the exhaust space (10i, 10j) due to the second joint (18d).

In this embodiment, the third coupling part (18e) is exemplified as being positioned in an area where the rear space part (10f) and the upper space part (10i) overlap or in an area very close thereto. This third coupling part (18e) may be positioned adjacent to the rear fan assembly (100) positioned in the rear space part (10f).

In this manner, an electrical component related to the rear fan assembly (100), such as a capacitor connected to the rear fan assembly (100), can be connected to the third coupling portion (18e). That is, the third coupling portion (18e) can simultaneously perform the role of providing a structure for connection between the expansion plate (18) and the cabinet (13) and the role of providing a structure for installation of an electrical component related to the rear fan assembly (100).

[Exhaust duct]

Fig. 34 is a cross-sectional side view showing the side shape of an exhaust duct, Fig. 35 is a plan view showing a state in which a duct bracket is installed on the upper surface of a cavity, and Fig. 36 is a drawing showing a state in which an exhaust duct is installed on a duct bracket.

Referring to FIGS. 33 to 35, the exhaust duct (70) can form a path inside that is connected to the circulating air outlet (11b). As an example, the exhaust duct (70) can be formed in a polyhedral shape in which the front-back length is much longer than the lateral length and the vertical length.

The rear end of the exhaust duct (70) can be placed between the rear surface of the cavity (11) and the circulating air outlet (11b). And the front end of the exhaust duct (70) can be placed between the center of the front-rear direction of the cavity (11) and the front surface of the cavity (11).

For example, the rear end of the exhaust duct (70) may be positioned very close to the rear surface of the cavity (11), and the front end of the exhaust duct (70) may be positioned very close to the front surface of the cavity (11).

A space is formed inside the exhaust duct (70), and this space can form a flow path (70a) that is connected to the circulating air outlet (11b) inside the exhaust duct (70). A duct inlet (70b) and a duct outlet (70c) can be provided in this exhaust duct (70).

The duct inlet (70b) is provided so that the duct (70a) can be opened toward the circulating air outlet (11b) on one side of the longitudinal direction of the duct (70a). In addition, the duct outlet (70c) is provided so that the duct inside the exhaust duct (70) can be opened toward the common exhaust port (3a).

As an example, the duct inlet (70b) may be formed in a form in which the bottom surface of the exhaust duct (70) is open. At least a portion of the duct inlet (70b) may overlap the circulating air outlet (11b) in the vertical direction.

And the duct outlet (70c) may be formed in a form in which a portion of the upper surface of the exhaust duct (70) is open. The duct outlet (70c) may be positioned at a position that is tilted forward from the center of the front-rear direction of the exhaust duct (70). This duct outlet (70c) may be positioned adjacent to the common exhaust port (3a).

In the lateral direction, the duct outlet (70c) may be arranged at a position closest to the common exhaust outlet (3a) among the multiple exhaust outlets (2, 3, 4) arranged laterally. This duct outlet (70c) may be arranged to overlap at least a portion of the common exhaust outlet (3a) in the vertical direction.

The cooking appliance of the present embodiment may further include a humidity sensor (7). The humidity sensor (7) is installed in the exhaust duct (70) and is provided to measure humidity in the exhaust path (70a).

The above humidity sensor (7) is provided to measure the humidity of air flowing into the duct (70a) through the circulating air outlet (11b) in the cooking room. In order for the humidity of air flowing into the duct (70a) to be effectively measured by the humidity sensor (7), a duct (70a) of sufficient length is required.

To this end, the circulating air outlet (11b) is positioned at a rearwardly tilted position in the upper space (10i), the duct outlet (70c) is positioned at a forwardly tilted position in the upper space (10i), and the exhaust duct (70) can be formed to a length sufficient to cover them.

The exhaust duct (70) of the present embodiment may be arranged between the upper surface of the cavity (11) and the upper surface of the cabinet (13) in the vertical direction. This exhaust duct (70) may include a height change section (71).

The height change section (71) is a section in which the height changes along the longitudinal direction of the flow path (70a) of the exhaust duct (70). For example, the height change section (71) may be a section in which the height changes along the forward-backward direction of the exhaust duct (70).

According to the present embodiment, the circulating air outlet (11b) provided in the cavity (11) is positioned lower than the second exhaust port (3) provided on the upper surface of the cabinet (13). In the height change section (71), the height of the exhaust duct (70) may decrease in the direction toward one side of the longitudinal direction of the flow path (70a), for example, toward the rear.

That is, in the height change section (71), the upper surface of the exhaust duct (70) can form a slope whose height decreases as it goes toward one side of the longitudinal direction of the flow path (70a).

In other words, in the height change section (71), the height of the exhaust duct (70) may increase in the direction toward the other side of the longitudinal direction of the duct (70a), for example, toward the front.

In the height change section (71), a passage space (10k) may be formed between the upper surface of the exhaust duct (70) and the upper surface of the cabinet (13). The passage space (10k) may be formed on the upper side of the exhaust duct (70) as a passage that laterally connects a space on one side of the upper space (10i) of the exhaust duct (70) and a space on the other side of the upper space (10i) of the exhaust duct (70). In the present embodiment, the passage space (10k) may be formed in a form in which the upper and lower widths of the passage space (10k) expand as it goes toward the rear.

Meanwhile, the cooking appliance of the present embodiment may further include a duct bracket (75). The duct bracket (75) may be provided for coupling between the exhaust duct (70) and the cavity (11). This duct bracket (75) may be coupled to the upper surface of the cavity (11). And the exhaust duct (70) may be detachably coupled to the duct bracket (75).

As an example, a duct bracket (75) may include a bracket body part (76) and a flange part (77).

The bracket body part (76) is a part provided for joining the duct bracket (75) and the exhaust duct (70) among the duct brackets (75). The bracket body part (76) can be joined to the upper surface of the cavity (11) and joined to the exhaust duct (70).

The flange portion (77) is a portion provided for joining the duct bracket (75) and the cavity (11) among the duct brackets (75). The flange portion (77) can be joined to the upper surface of the cavity (11) to join the bracket body portion (76) to the upper surface of the cavity (11).

The flange portion (77) can form a plane parallel to the upper surface of the cavity (11) and can be arranged to be in vertical contact with the upper surface of the cavity (11). The connection between the flange portion (77) and the cavity (11) can be made by a joining method such as welding.

Referring to FIGS. 35 and 36, a joining surface (72) may be provided in the exhaust duct (70). The joining surface (72) may be provided at the lower end of the exhaust duct (70) and may form a surface that is in vertical contact with the upper surface of the bracket body (76). As an example, the upper surface of the bracket body (76) may form a horizontal plane perpendicular to the vertical axis, and the joining surface (72) may form a plane parallel thereto.

And the duct bracket (75) may further include a first duct joint (78) that is joined to the joining surface (72). The first duct joint (78) may be detachably joined to the joining surface (72) while the joining surface (72) is in vertical contact with the bracket body (76).

As an example, the first duct joint (78) may include a vertical projection (78a) and a horizontal projection (78b). The vertical projection (78a) may be formed in a shape that protrudes upward from the bracket body (76). And the horizontal projection (78b) may be formed in a shape that protrudes horizontally from the vertical projection (78a), more specifically, in the front-back direction.

As an example, the transverse projection (78b) may protrude rearwardly from the upper end of the vertical projection (78a). In this embodiment, the first duct joint portion (78) is exemplified as being formed in a “Γ” shape protruding from the bracket body portion (76).

The vertical protrusion (78a) can penetrate the joint surface (72) vertically through a slit (73) formed in the joint surface (72). The horizontal protrusion (78b) protruding from the upper end of the vertical protrusion (78a) can restrict the upward movement of the duct bracket (75) on the upper side of the joint surface (72).

The slit (73) may be provided so that the entire first duct joint (78) can pass through the slit (73). When the horizontal projection (78b) passes through the slit (73) and is positioned on the upper side of the joint surface (72) and the joint surface (72) is in contact with the upper surface of the bracket body (76), and the exhaust duct moves rearward so that the horizontal projection (78b) can move to the rear side of the slit (73), the horizontal projection (78b) can restrain the upward movement of the duct bracket (75) on the upper side of the joint surface (72).

By fitting the first duct joint (78) and the joining surface (72) formed in this manner, the exhaust duct (70) can be temporarily fixed to the duct bracket (75). That is, by fitting the first duct joint (78) and the joining surface (72), the position of the exhaust duct (70) relative to the duct bracket (75) can be temporarily fixed.

As an example, a plurality of first duct joints (78) can be arranged laterally at a predetermined interval on the duct bracket (75). Accordingly, the exhaust duct (70) can be temporarily fixed by the first duct joints (78) at a plurality of points along the lateral direction.

The duct bracket (75) may further include a second duct joint (79). The second duct joint (79) may be provided for jointing between the exhaust duct (70) and the duct bracket (75) using a fastening member (s) such as a screw.

As an example, the fastening member (s) can penetrate the upper surface of the bracket body (76) and the joining surface (72) to join the duct bracket (75) and the exhaust duct (70). A second duct joining member (79) can be provided for joining with this fastening member (s).

As an example, the second duct joint (79) may form a plane that is convex upward from the upper surface of the bracket body (76), and a fastening hole may be provided in the second duct joint (79) for fastening with a fastening member (s).

As described above, the exhaust duct (70) can be installed on the upper surface of the cavity (11) via a duct bracket (75).

In order to install the exhaust duct (70) in the cavity (11) so that the exhaust duct (70) can be separated from the cavity (11) as needed, it is necessary to attach the exhaust duct (70) to the cavity (11) using a fastening member such as a screw.

However, in this case, fastening holes for screw fastening must be formed in the cavity (11), and it is not desirable for unnecessary damage to be inflicted on the cavity (11) due to these fastening holes.

In addition, during the process of fastening the screw to the cavity (11), the damage to the cavity (11) may become greater, and during the process of removing the screw from the cavity (11) or refastening the screw to the cavity (11) for disassembling and reassembling the exhaust duct (70), the cavity (11) may be severely damaged.

In order to prevent damage to the cavity (11), the exhaust duct (70) may be welded or bonded to the cavity (11). However, in this case, it becomes very difficult to separate the exhaust duct (70) from the cavity (11), and the cavity (11) may be damaged during the process of separating the exhaust duct (70) from the cavity (11).

Considering these points, in this embodiment, a duct bracket (75) is welded or bonded to a cavity (11), and an exhaust duct (70) can be detachably connected to the duct bracket (75).

Accordingly, since the connection between the cavity (11) and the duct bracket (75) is made by welding or adhesive bonding, damage to the cavity (11) due to perforation, etc. can be minimized.

In addition, since the exhaust duct (70) is detachably connected to the duct bracket (75) attached to the cavity (11) in this way, the exhaust duct (70) can be easily and quickly separated from the cavity (11) as needed, and damage to the cavity (11) that may occur during the disassembly and reassembly process of the exhaust duct (70) can be minimized.

In addition, since the exhaust duct (70) can be temporarily fixed and guided to a joining position relative to the duct bracket (75) by the fitting connection between the first duct joint (78) and the joining surface (72), the installation work of the exhaust duct (70) can be performed more easily and quickly.

Figure 37 is an enlarged view of the lamp cover and its surroundings, and Figure 38 is a plan view of the lamp cover illustrated in Figure 37.

Referring to FIG. 31, FIG. 37 and FIG. 38, a lamp (8) may be provided inside the main body (10). The lamp (8) is provided so as to shine light into the cooking chamber (10a).

As an example, the lamp (8) may be installed on the upper surface of the cavity (11). At least a part of the lamp (8) may be exposed to the upper side of the cavity (11). For example, a part of the lamp (8) installed on the upper surface of the cavity (11) may be exposed to the upper space (10i).

The cooking appliance of the present embodiment may include a lamp cover (80). The lamp cover (80) is provided so as to be able to cover the lamp (8). The lamp cover (80) may cover the lamp (8) from the upper side of the cavity (11) so that the space surrounding the lamp (8) is separated from the upper space (10i).

As an example, the lamp cover (80) may include a cover upper surface portion (81) and a cover side portion (82). The cover upper surface portion (81) covers the lamp (8) from the upper side, and the cover side portion (82) is provided to surround the lamp from the horizontal outer side.

As an example, the cover upper surface (81) can form a horizontal plane that is spaced apart from the upper surface of the cavity (11) in the vertical direction by a predetermined distance. In addition, the cover side surface (82) can form a vertical wall surface that connects the upper surface of the cavity (11) and the cover upper surface (81).

As an example, the lamp cover (80) may be formed in a hexahedral shape with an open lower side. The lamp (8) may be arranged in a form surrounded by the cover upper surface portion (81) and the cover side portion (82).

The lamp cover (80) may further include a sealing portion (83). The sealing portion (83) may be provided so as to be in surface contact with the upper surface of the cavity (11) and may be connected to the lower end of the cover side portion (82). As an example, the sealing portion (83) may extend horizontally from the lower end of the cover side portion (82) and form a plane parallel to the upper surface of the cavity (11).

The sealing portion (83) can be in surface contact with the upper surface of the cavity (11) and can serve to ensure that the lamp cover (80) is in close contact with the upper surface of the cavity (11). Accordingly, the space inside the lamp cover (80) surrounding the lamp (8) can be reliably separated from the upper space (10i), and the inflow of air from the upper space (10i) into the interior of the lamp cover (80) can be effectively blocked.

The lamp cover (80) of the present embodiment can be placed between the upper surface of the cavity (11) and the upper surface of the cabinet (13) in the vertical direction. In addition, the lamp cover (80) can be placed adjacent to the front of the main body (10).

According to the present embodiment, the front plate (12) may be formed so that the upper end of the front plate (12) is positioned higher than the upper surface of the cavity (11). An upper surface portion (12a) may be provided on the upper end of the front plate (12). The upper surface portion (12a) may form a horizontal surface that protrudes rearwardly from a position higher than the cavity (11).

The lamp cover (80) may be placed adjacent to the front plate (12). As an example, the lamp cover (80) may be placed at a position where the front end of the lamp cover (80) is in close contact with the back surface of the front plate (12).

The cover upper surface (81) of the lamp cover (80) can form an inclined surface whose height changes along the forward and backward directions. As an example, the cover upper surface (81) can form an inclined surface whose height decreases as it goes toward the rear.

The above lamp cover (80) can be coupled to the front plate (12). A cover coupling portion (84) can be provided on the lamp cover (80). The cover coupling portion (84) can protrude rearward from the lamp cover (80) so as to come into vertical contact with the upper surface (12a) of the front plate (12).

This cover joint (84) can be formed in a shape that protrudes upward and rearward from the front end of the cover upper surface (81). As an example, the cover joint (84) can be formed in a shape that protrudes in a “Γ” shape from the front end of the cover upper surface (81). As an example, the connection between the cover joint (84) and the upper surface (12a) can be made by a fastening member (s) such as a screw.

According to the present embodiment, the lamp cover (80) is only coupled to the front plate (12) and not coupled to the cavity (11). For example, the lamp cover (80) is only coupled to the upper surface of the cavity (11) through the sealing portion (83) and is not coupled to the cavity (11). This is to enable the lamp cover (80) to be detachably coupled to the main body (10) while avoiding unnecessary damage to the cavity (11).

To this end, the lamp cover (80) can be detachably coupled to the main body (10) by being coupled to the front plate (12) through the cover coupling portion (84) and the upper surface portion (12a). That is, the cover coupling portion (84) can be provided so that the lamp cover (80) can be coupled to the front plate (12) instead of the cavity (11).

According to the present embodiment, in order to illuminate the cooking chamber (10a), at least a portion of the lamp (8) is exposed to the interior of the cooking chamber (10a). In addition, in order for the lamp (8) to be connected to other electrical components, a portion of the lamp (8) is exposed to the outside of the cooking chamber (10a). For example, a connection between a wire for power supply and the lamp (8) can be made through a portion of the lamp (8) exposed to the outside of the cooking chamber (10a).

According to the present embodiment, the lamp (8) is installed on the upper surface of the cavity (11), and thus a part of the lamp (8) is exposed to the upper space of the cavity (11), i.e., the upper space portion (10i). As a part of the lamp (8) is exposed to the upper space portion (10i), the lamp (8) may be exposed to vapor and heat.

Among the cooking gas that passes through the upper space (10i) after being sucked in by the blower (100, 200), oil vapor, hot vapor, etc. may be included. The cooking gas containing such oil vapor and hot vapor may come into contact with the lamp (8) during the process of passing through the upper space (10i), which may cause contamination or malfunction of the lamp (8).

Considering these points, in this embodiment, a lamp cover (80) is installed in the upper space (10i). The lamp cover (80) covers the lamp (8) from the upper side of the cavity (11) so that the space surrounding the lamp (8) is separated from the upper space (10i), thereby protecting the lamp (8) from vapor and heat.

In conventional cooking appliances, the blower is placed in the upper space, not the rear space. In this case, sufficient space must be secured in the upper space for installing the blower. In such conventional cooking appliances, the height of the upper space must be considerably higher than that of the upper space (10i) of the cooking appliance of the present embodiment.

In addition, as the blower is arranged in the upper space, a flow path forming member for forming an exhaust path within the upper space is installed in the upper space in the conventional cooking appliance. This flow path forming member forms an exhaust path within the upper space that connects the exhaust port arranged on the front side of the conventional cooking appliance and the blower.

In conventional cooking appliances, the guiding member may be formed in a shape including a pair of side walls spaced apart laterally by a predetermined distance and a bottom surface connecting the side walls from the bottom. For example, the guiding member may be formed in a "U" shape.

The above-mentioned flow-forming member can be installed on the upper side of the cavity. The flow-forming member can be detachably installed on the upper side of the cavity, and the lower surface of the flow-forming member is secured to the upper surface of the cavity.

The lamp installed on the upper surface of the cavity is placed on the lower side of the flow path forming member. That is, in conventional cooking appliances, the lamp is covered by the lower surface of the flow path forming member and is not exposed to the exhaust path. Therefore, in conventional cooking appliances, in addition to the flow path forming member, a separate structure for covering the lamp is not required.

In contrast, in the cooking appliance of this embodiment, the blower (100, 200) is arranged in the rear space (10f). Therefore, in the cooking appliance of this embodiment, the space required for installing the blower (100, 200) does not need to be secured in the upper space (10i). In the cooking appliance of this embodiment, the height of the upper space (10i) can be significantly lowered compared to the height of the upper space of a conventional cooking appliance.

As the height of the upper space (10i) decreases, it becomes difficult to secure the space required for installing a structure such as a flow path forming member of a conventional cooking appliance in the upper space (10i). In addition, in the cooking appliance of the present embodiment, since the blower (100, 200) and the flow path forming member (30) are arranged in the rear space (10f), there is no need to install a structure for forming an exhaust path in the upper space (10i).

As the height of the upper space (10i) is lowered, the effect of shortening the vertical length of the cooking appliance and reducing the size of the entire cooking chamber compared to the volume of the cooking chamber (10a) can be provided. However, since a structure such as a conventional cooking appliance's guiding member is not installed in the upper space (10i), a problem occurs in which the lamp (8) is exposed to the upper space (10i).

Considering these points, in this embodiment, a lamp cover (80) is installed in the upper space (10i), and the lamp cover (80) can cover the lamp (8) from the upper side of the cavity (11) so that the space surrounding the lamp (8) is separated from the upper space (10i). As a result, the goal of shortening the vertical length of the upper space (10i) and the goal of protecting the lamp (8) from vapor and heat can be satisfied at the same time.

[Other examples of lamp covers]

Fig. 39 is a rear perspective view showing a cooking appliance to which another example of a lamp cover is applied, and Fig. 40 is a perspective view showing the lamp cover shown in Fig. 39 in an exploded state. In addition, Fig. 41 is an exploded perspective view showing the lamp cover shown in Fig. 40 in an exploded state, and Fig. 42 is an exploded perspective view showing the vent grill and lamp cover in an exploded state.

Referring to FIGS. 39 to 41, the lamp cover (85) may be provided in a form including an opening/closing cover (86b). This lamp cover (85) may include a cover upper surface portion (86), a cover side portion (87), a sealing portion (88), and a cover joining portion (89), similar to the lamp cover exemplified in the above-described embodiment, and may further include an opening/closing cover (86b).

A through hole (86a) may be provided on the upper surface of the lamp cover (85) of the present embodiment. The through hole (86a) may be formed to open the upper side of the internal space of the lamp cover (85) and penetrate vertically through the upper surface portion (86) of the cover. By means of this through hole (86a), the lamp (8) may be exposed to the upper side of the lamp cover (85).

The opening/closing cover (86b) is installed on the lamp cover (85), more specifically, on the cover upper surface (86), and can open/close the through hole (86a). As an example, the opening/closing cover (86b) can be detachably connected to the cover upper surface (86). For example, the opening/closing cover (86b) covers the through hole (86a) from the upper side, and can be detached from the cover upper surface (86) upward.

Referring to FIGS. 39 to 42, the lamp cover (85) may be placed on the lower side of any one of the plurality of second exhaust ports (2). For example, at least a portion of the lamp cover (85) may be placed on the vertical lower side of any one of the plurality of second exhaust ports (2).

Meanwhile, the cooking appliance may further include at least one vent grill (9). Each vent grill (9) may cover the second exhaust port (3) or the cold air inlet port (5), respectively, and may be coupled to the cabinet (13). Each vent grill (9) may be detachably coupled to the cabinet (13).

For example, each vent grill (9) can be mounted on the upper surface of the cabinet (13) and cover the second exhaust port (3) or the cold air inlet port (5), and can be lifted upward from the upper surface of the cabinet (13) and separated from the cabinet (13).

As an example, the cover (86b) may be arranged on the vertical lower side of one of the plurality of second exhaust ports (2). With respect to the vertical direction, the through hole (86a) may be arranged between the second exhaust port (3) and the lamp (8), and the cover (86b) may be arranged between the vent grille (9) installed in the second exhaust port (3) and the lamp (8). When viewed from above, when the vent grille (9) is removed from the second exhaust port (3), the cover (86b) becomes visible, and when the cover (86b) is removed in this state, the lamp (8) becomes visible.

As the lamp cover (85) and the opening/closing cover (86b) are installed inside the main body (10) in the above-mentioned form, maintenance work on the lamp (8) can be performed while the vent grill (9) and the opening/closing cover (86b) are sequentially removed from the cabinet (13) and the cover upper surface (86).

That is, the lamp cover (85) of the present embodiment can provide the effect of enabling maintenance work on the lamp (8) to be performed easily and quickly by enabling access to the lamp (8) simply by separating the vent grill (9) and the opening/closing cover (86b).

[Type of exhaust through exhaust space]

Referring to FIG. 16 and FIGS. 31 to 33, an upper space (10i) may be formed on the upper side of the cavity (11). In addition, an extended upper space (10j) may be formed on the upper side of the side space (10e) other than the main chamber (10b, 10c, 10d).

As described above, the upper space (10i) and the extended upper space (10j) are connected as one on the upper side of the cavity (11), and accordingly, an exhaust space (10i, 10j) can be formed on the upper side of the cavity (11) and the side space (10e).

The expanded upper space (10j) can be formed by an expansion plate (18) that divides the side space (10e) into upper and lower sections. In the present embodiment, the expansion plate (18) can serve to expand the exhaust space (10i, 10j) laterally by making the exhaust space (10i, 10j) a space that includes not only the upper space (10i) but also the expanded upper space (10j). In addition, the expansion plate (18) can serve to separate the side space (10e) from the exhaust space (10i, 10j).

As the exhaust space (10i, 10j) is expanded into a space that includes both the upper space (10i) and the expanded upper space (10j), the size of the flow path required for the air to be discharged to the second exhaust port (3) through the exhaust space (10i, 10j) can be expanded. In particular, the size of the exhaust space (10i, 10j) can be expanded laterally by the size of the expanded upper space (10j).

That is, the expansion plate (18) of the present embodiment can provide an effect of allowing the size of the exhaust space (10i, 10j) to be expanded by dividing the side space (10e) so that an expanded upper space (10j) that can be connected to the upper space (10i) can be formed.

As described above, in the cooking appliance of the present embodiment, the blower (100, 200) is placed in the rear space (10f) rather than the upper space (10i). Accordingly, there is no need to secure the space required for installing the blower (100, 200) in the upper space (10i), so the height of the upper space (10i) can be lowered compared to when the blower is installed in the upper space.

In the cooking appliance of the present embodiment, one of the methods for reducing the size of the entire cooking appliance while minimizing the reduction in the volume of the cooking chamber, that is, reducing the height of the entire cooking appliance while minimizing the reduction in the height of the cooking chamber, is to reduce the height of the upper space (10i).

Considering these points, in the cooking appliance of the present embodiment, the height of the upper space (10i) is set lower than the height of the upper space of a conventional cooking appliance. That is, in the cooking appliance of the present embodiment, the height of the upper space (10i) is set to a height significantly lower than the height at which the rear fan assembly (100) or the corner fan assembly (200) can be installed.

As the height of the upper space (10i) is lowered in this way, the volume of the upper space (10i) is also inevitably reduced. Since the upper space (10i) is a space related to exhaust, if the volume of the upper space (10i) is reduced, the size of the flow path required for the air discharged to the second exhaust port (3) is inevitably reduced accordingly.

If the size of the path required for the flow of air discharged through the second exhaust port (3) is reduced, the exhaust performance of the cooking appliance inevitably deteriorates. In addition, if the exhaust performance of the cooking appliance deteriorates, the intake performance of the cooking appliance also deteriorates, which ultimately results in the cooking gas removal performance of the cooking appliance deteriorating.

Considering these points, in the present embodiment, the expanded upper space (10j) is separated from the side space (10e) by an expansion plate (18) that divides the side space (10e) into upper and lower parts, and this expanded upper space (10j) is connected to the upper space (10i), thereby allowing the size of the entire exhaust space (10i, 10j) including the upper space (10i) to be expanded. Accordingly, the size of the flow path required for the air discharged to the second exhaust port (3) through the exhaust space (10i, 10j) can be effectively expanded.

In this way, if the size of the path required for the flow of air discharged to the second exhaust port (3) through the exhaust space (10i, 10j) is expanded, the exhaust performance of the cooking appliance can be improved accordingly, and ultimately the cooking gas removal performance of the cooking appliance can be improved.

Meanwhile, structures such as an exhaust duct (70) and a lamp cover (80) are arranged in the exhaust space (10i, 10j). These have a shape that protrudes from the upper surface of the cavity (11) into the exhaust space (10i, 10j) to perform their respective functions.

For example, the exhaust duct (70) is formed in a shape protruding from the upper surface of the cavity (11) to form a path for the flow of air discharged from the cooking room. And the lamp cover (80) is formed in a shape protruding from the upper surface of the cavity (11) to cover the lamp from the upper side and to be coupled to the front plate (12).

The exhaust duct (70) and the lamp cover (80) may each be formed in a shape including an inclined surface. That is, the exhaust duct (70) and the lamp cover (80) are inevitably formed in a shape protruding from the upper surface of the cavity (11) in order to perform their respective functions, but may be formed in a shape that allows the flow resistance generated by the exhaust duct (70) and the lamp cover (80) in the exhaust space (10i, 10j) to be reduced.

That is, in the present embodiment, the size of the exhaust space (10i, 10j) is expanded by the expanded upper space portion (10j), and accordingly, the size of the flow path required for the air to be discharged to the second exhaust port (3) through the exhaust space (10i, 10j) is expanded, and the exhaust duct (70) and the lamp cover (80) arranged in the exhaust space (10i, 10j) are provided in a shape that can reduce the flow resistance caused by them, so that the air to be discharged to the second exhaust port (3) through the exhaust space (10i, 10j) can flow smoothly.

Accordingly, the cooking appliance of the present embodiment can provide cooking gas removal performance equivalent to or superior to that of conventional cooking appliances with similar cooking capacity while being smaller in overall size.

In addition, the above-mentioned expansion plate (18) can act as a barrier blocking the side space (10e) and the exhaust space (10i, 10j). Accordingly, the side space (10e) can be separated from the exhaust space (10i, 10j) by the expansion plate (18).

That is, a space is formed on the upper side of the expansion plate (18) by the expansion plate (18) in which the upper space (10i) and the expanded upper space (10j) are connected, but the passage between the side space (10e) and the exhaust space (10i, 10j) is blocked by the expansion plate (18).

According to the present embodiment, the side space (10e) is connected to the lower space formed between the intake port (1) and the cavity (11). Accordingly, the side space (10e) can be said to be a space connected to the intake port (1). And the exhaust space (10i, 10j) can be said to be a space connected to the second exhaust port (3). In other words, the side space (10e) can be said to be a space related to intake, and the exhaust space (10i, 10j) can be said to be a space related to exhaust.

The expansion plate (18) can separate the space related to exhaust from the space related to intake by separating the exhaust space (10i, 10j) from the side space (10e). Accordingly, the space related to exhaust is expanded by the expansion upper space (10j), and the space related to intake can be expanded by the amount of space occupied by the side space (10e).

That is, since the exhaust space (10i, 10j) and the side space (10e) are separated by the expansion plate (18), the space associated with exhaust and the space associated with intake can be secured to a sufficient size required for intake or exhaust, respectively.

In addition, since the exhaust space (10i, 10j) and the side space (10e) are separated by the expansion plate (18), the phenomenon in which air in the exhaust space (10i, 10j) is re-absorbed into the blower (100, 200), i.e. the occurrence of a backflow phenomenon, can be effectively suppressed, so that the exhaust performance of the cooking appliance can be effectively improved.

Meanwhile, in the cooking appliance of the present embodiment, a plurality of second exhaust ports (3) may be arranged. Each second exhaust port (3) is arranged on the upper surface of the main body (10), but is arranged at a position adjacent to the front of the main body (10), and may be connected to the exhaust space (10i, 10j).

In the main body (10), a cold air inlet (5) and a plurality of second exhaust ports (3) can be arranged laterally. Additionally, any one of the plurality of second exhaust ports (3) can be provided as a common exhaust port (3a).

In this embodiment, the cold air inlet (5) is arranged on the left side of the second exhaust ports (3), and one of the plurality of second exhaust ports (3) arranged on the far right is provided as a common exhaust port (3a).

At least a part of the common exhaust port (3a) can be arranged to overlap with at least a part of the duct outlet (70c) provided in the exhaust duct (70). That is, when viewed from above, at least a part of the duct outlet (70c) can be exposed upward through the common exhaust port (3a). Accordingly, air discharged through the duct outlet (70c) can be effectively discharged through the common exhaust port (3a).

Some of the air that has entered the cooking chamber (10b, 10c, 10d) through the cold air inlet (5) may be introduced into the cooking chamber (10a). The air that has entered the cooking chamber (10a) may be discharged through the exhaust duct (70) together with steam, gas, etc. generated in the cooking chamber (10a) during the cooking process of the cooking appliance.

Air drawn into the exhaust duct (70) can be discharged through the duct outlet (70c), and air discharged from the exhaust duct (70) can be discharged to the outside of the cooking appliance through the common exhaust port (3a). In other words, the common exhaust port (3a) can be an outlet used to discharge air discharged from the cooking chamber to the outside of the cooking appliance.

In this embodiment, at least a portion of the common exhaust port (3a) is exemplified as being arranged on the left side of the expanded upper space portion (10j). This common exhaust port (3a) can be arranged on the upper side of the boundary between the upper space portion (10i) and the expanded upper space portion (10j). That is, when viewed from above, the boundary between the upper space portion (10i) and the expanded upper space portion (10j) can be exposed to the upper side of the cooking appliance through the common exhaust port (3a).

As an example, approximately the left half of the common exhaust port (3a) may be placed on the upper side of the upper space portion (10i), and the remaining half of the common exhaust port (3a) may be placed on the upper side of the extended upper space portion (10j).

This common exhaust port (3a) can discharge air discharged from the exhaust duct (70) and air drawn into the exhaust space (10i, 10j) from the blower (100, 200) together. In other words, steam and gas discharged from the cooking chamber and cooking gas sucked in through the blower (100, 200) can be discharged together through the common exhaust port (3a).

According to the present embodiment, the exhaust space (10i, 10j) includes an upper space (10i) and an expanded upper space (10j), and air sucked through the blower (100, 200) can flow not only to the upper space (10i) but also to the expanded upper space (10j). In particular, air flowing from the blower (100, 200) to the expanded upper space (10j) can be discharged to the outside of the cooking appliance through the common exhaust port (3a).

Of course, the air flowing from the blower (100, 200) to the expanded upper space (10j) is not necessarily discharged to the outside of the cooking appliance only through the common exhaust port (3a), and may also be discharged to the outside of the cooking appliance through a second exhaust port (3) other than the common exhaust port (3a).

If the expansion plate (18) is not provided inside the main body (10) and, accordingly, the expansion upper space (10j) is not formed inside the main body (10), the area occupied by the exhaust space (10i, 10j) is inevitably reduced to only the upper space (10i).

In this case, most of the lower area of the common exhaust port (3a) is occupied by the exhaust duct (70), and it becomes difficult to form a passage connecting the common exhaust port (3a) and the exhaust space (10i, 10j).

In addition, if the expansion plate (18) is not provided inside the main body (10), the common exhaust port (3a) is directly connected to the side space (10e). In this case, the suction force of the rear fan assembly (100) acting on the side space (10e) may affect the periphery of the common exhaust port (3a).

In this case, it becomes considerably difficult for the air flowing from the blower (100, 200) to the exhaust space (10i, 10j) to be discharged to the outside of the cooking appliance through the common exhaust port (3a). As a result, only the steam and gas discharged from the cooking chamber are mainly discharged through the common exhaust port (3a), and the cooking gas sucked in by the blower (100, 200) can hardly be discharged.

In contrast, in the cooking appliance of the present embodiment, the side space (10e) and the upper extended upper space (10j) are separated by the expansion plate (18), and the area occupied by the exhaust space (10i, 10j) can be expanded not only to the upper space (10i) but also to the upper extended upper space (10j), which is an area arranged below the common exhaust port (3a).

Accordingly, the cooking appliance of the present embodiment can discharge steam and gas discharged from the cooking chamber and cooking gas sucked in through the blower (100, 200) together through the common exhaust port (3a).

[Absence of rear support]

FIG. 43 is a rear perspective view showing a state in which a rear fan assembly is removed from a cooking appliance according to the first embodiment of the present invention, FIG. 44 is a rear perspective view showing the rear support member shown in FIG. 43 separated, and FIG. 45 is a side view showing a state in which a cavity and a rear support member are joined. In addition, FIG. 46 is a bottom perspective view showing an enlarged view of a joining portion between the cavity and the rear support member shown in FIG. 45, FIG. 47 is a side view showing a state in which a rear plate is joined to the rear support member shown in FIG. 45, and FIG. 48 is a side sectional view showing a joining structure between a cavity, a rear support member, and a rear plate.

Referring to FIGS. 43 to 45, the cooking appliance of the present embodiment may include a rear support member (90). The rear support member (90) may be arranged on the rear side of the cavity (11).

As described above, a front plate may be placed on the front side of the cavity (11). The front plate (12) and the rear support member (90) may be placed spaced apart in the front-back direction with the cavity (11) interposed therebetween and may be respectively coupled to the cavity (11).

As an example, the front plate (12) may be coupled to the front surface of the cavity (11), and the rear support member (90) may be coupled to the back surface of the cavity (11). As another example, the front plate (12) may be formed integrally with the cavity (11) to form the front surface of the cavity (11).

According to the present embodiment, the front plate (12) may be formed so that the lower end (12b) of the front plate (12) is positioned lower than the bottom surface of the cavity (11). For example, at least a portion of the front plate (12) may be positioned between the cavity (11) and the base plate (14).

The rear support member (90), like the front plate (12), may be formed so that the lower end of the rear support member (90) is positioned lower than the bottom surface of the cavity (11). For example, at least a portion of the rear support member (90) may be positioned between the cavity (11) and the base plate (14).

To this end, at least a portion of the rear support member (90) may protrude to a position lower than the bottom surface of the cavity (11). This rear support member (90) may contact the bottom surface at a position lower than the cavity (11) and support the cavity (11).

The rear support member (90) may include a front coupling portion (91) and a lower support portion (92). The front coupling portion (91) is provided so that it can be coupled to the back surface of the cavity (11). And the lower support portion (92) may protrude downward from the front coupling portion (91).

The lower end of the lower support member (92) can be positioned lower than the bottom surface of the cavity (11). This lower support member (92) can contact the bottom surface at a position lower than the cavity (11) and support the front joint member (91) and the cavity (11) coupled thereto.

Preferably, the lower end of the lower support member (92) may be positioned at a position corresponding to the position of the lower end (12b) of the front plate (12). For example, the protrusion length of the lower support member (92) with respect to the bottom surface of the cavity (11) and the protrusion length of the front plate (12) may be set to be the same. Accordingly, the rear support member (90) may support the cavity (11) so that the cavity (11) can be maintained approximately horizontally.

In the forward and backward direction, a rear support member (90) can be placed between the cavity (11) and the rear plate (15). This rear support member (90) can be combined with the cavity (11) and the rear plate (15), respectively.

To this end, the rear support member (90) may further include a rear coupling portion (93) and a connecting portion (94). The rear coupling portion (93) is provided so as to be coupled to the front of the rear plate (15). In addition, the connecting portion (94) protrudes rearward from the front coupling portion (91) and may connect the front coupling portion (91) and the rear coupling portion (93).

The connecting portion (94) is arranged in the rear space (10f) and can be arranged on the lower side of the rear fan assembly (100). With respect to the vertical direction, the connecting portion (94) can be arranged between the rear fan assembly (100) and the base plate (14). This connecting portion (94) is provided so that air in the rear space (10f) can flow in the vertical direction while passing through the connecting portion (94).

For this purpose, upper and lower penetration holes (94a) may be provided in the rear support member (90). The upper and lower penetration holes (94a) are provided so as to form a passage that opens the space between the cavity (11) and the base plate (14), i.e., the lower space portion, and the rear fan assembly (100).

As an example, the connecting portion (94) may form a horizontal plane that blocks the lower space portion and the rear fan assembly (100), and the upper and lower penetration holes (94a) may be formed to penetrate the connecting portion (94) in the upper and lower directions. The upper and lower penetration holes (94a) may form a passage necessary for air introduced into the lower space portion through the intake port (1) to pass through the rear support member (90) and flow toward the rear fan assembly (100).

That is, the connecting portion (94) can serve to maintain the gap between the cavity (11) and the rear plate (15) so that sufficient space required for air flow in the rear space (10f) can be secured.

Referring to FIGS. 44 to 47, this front coupling portion (91) is in contact with the back surface of the cavity (11) in the front-back direction and can be coupled with the back surface of the cavity (11).

The connection between the cavity (11) and the front coupling portion (91) can be achieved by at least one of a connection using a fastening member (s) such as a screw, and a fitting connection. As an example, at least one of a fitting connection portion (91a) and a fastening hole (91b) can be provided in the front coupling portion (91). In the present embodiment, it is exemplified that both a fitting connection portion (91a) and a fastening hole (91b) are provided in the front coupling portion (91).

The fitting portion (91a) can be detachably joined to the back surface of the cavity (11). As an example, the lower end (11c) of the back surface of the cavity (11) can be formed to protrude further downward than the bottom surface of the cavity (11). The fitting portion (91a) is provided so that the lower end (11c) of the back surface of the cavity (11) can be fitted.

As an example, the fitting portion (91a) may be formed to protrude rearwardly in an “L” shape from the front fitting portion (91), and the lower end (11c) of the rear surface of the cavity (11) may be fitted between the front surface of the front fitting portion (91) and the rear surface of the fitting portion (91a).

When assembling the cooking appliance, when the cavity (11) is turned over so that the bottom surface of the cavity (11) faces upward, and the rear support member (90) is turned over so that the lower support member (92) faces upward, and the lower end (11c) of the rear surface of the cavity (11) is fitted into the fitting portion (91a) so that the rear support member (90) hangs over the rear surface of the cavity (11), a fitting connection between the cavity (11) and the rear support member (90) can be made.

By fitting the cavity (11) and the rear support member (90) in this manner, the rear support member (90) can be temporarily fixed to the cavity (11). In this state where the rear support member (90) is temporarily fixed to the cavity (11), the front coupling portion (91) can be in contact with the back surface of the cavity (11) in the front-back direction.

In this state, when fastening is performed by a fastening member (s) such as a screw, the rear support member (90) can be firmly connected to the cavity (11).

That is, since the position of the rear support member (90) relative to the cavity (11) can be guided and temporarily fixed by the fitting connection between the cavity (11) and the fitting portion (91a), the installation work of the rear support member (90) can be performed more easily and quickly.

As described above, the rear support member (90) installed on the rear side of the cavity (11) can support the cavity (11) so that the cavity (11) does not fall backwards during the assembly process of the cooking appliance.

As described above, a front plate (12) is installed on the front side of the cavity (11), and the lower end (12b) of the front plate (12) protrudes to a position lower than the bottom surface of the cavity (11). Therefore, if the front plate (12) is installed first with respect to the cavity (11) and the base plate (14) or the rear plate (15) is not installed yet, there is a high possibility that the cavity (11) will fall over to the rear side due to the height difference between the front side and the rear side of the cavity (11).

Considering these points, in this embodiment, the rear support member (90) is installed on the rear side of the cavity (11), and the rear side of the cavity (11) can be supported by the rear support member (90). That is, in this embodiment, the front plate (12) and the rear support member (90) arranged in the front-back direction with the cavity (11) interposed between them can support the cavity (11) on both sides in the front-back direction of the cavity (11).

Accordingly, even if the front plate (12) is installed first against the cavity (11) and the base plate (14) or the rear plate (15) is not installed yet, the cavity (11) can maintain a stable posture without falling over to the rear side and without being tilted to the front or rear side.

That is, the rear support member (90) of the present embodiment can play a role in stably maintaining the posture of the cavity (11) so that the cavity (11) does not fall to the rear during the assembly process of the cooking appliance, thereby contributing to enabling the assembly of the cooking appliance to be conveniently performed in a more stable environment, and can provide the effect of suppressing the occurrence of various safety accidents that may occur due to the cavity (11) falling over during the assembly process of the cooking appliance.

In addition, the rear support member (90) may be combined with at least one of the rear plate (15) and the base plate (14), as shown in FIGS. 47 and 48. In this embodiment, the rear support member (90) is exemplified as being combined with the rear plate (15) and the base plate (14), respectively.

As described above, the rear coupling member (93) can be coupled with the rear plate (15). And the lower end of the lower support member (92) can be coupled with the base plate (14). In this way, the rear support member (90) coupled with the rear plate (15) and the base plate (14), respectively, can effectively improve the structural stability of the cooking appliance by stably supporting the rear plate (15) and the base plate (14) to the cavity (11).

In addition, the rear support member (90) can provide an effect of increasing the suction flow rate by maintaining the gap between the cavity (11) and the rear plate (15) so that sufficient space required for air flow in the rear space (10f) can be secured.
