BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker, and more particularly, to a heating cooker in which an exhaust passage of a burner system having a relatively large calorific value is formed shorter than an exhaust passage of a burner system having a relatively small calorific value.

Heat cooker is a kitchen appliance for cooking food in a state in which food can be ingested by human beings. The cooker is a method of generating heat for heating food using electricity and by burning gas. It is largely divided into a method of generating heat for heating food.

In the method of generating heat for cooking food by burning gas, the food is cooked by heating a container containing the food to be cooked by the heat generated by the combustion of a mixed gas in which gas and air are mixed.

The heating cooker operated by the method of burning the gas is provided with a combustion unit. The combustion unit mixes gas with air to combust it, injects gas into the internal space, and gas is sucked into the combustion unit together with air in the vicinity of the injected gas.

Then, the mixed gas flowing into the combustion unit is uniformly mixed in the combustion unit, and after being uniformly mixed, the mixed gas is ignited to burn the gas, and heat generated by the combustion of the gas is radiated and conducted. The heat is transferred by the food is heated while cooking.

However, the heating cooking apparatus according to the prior art has a disadvantage in that the overall height of the combustion unit is increased as the gas is discharged upward from the lower portion of the combustion unit so that the gas and air are smoothly discharged after the gas and air are introduced into the combustion unit.

In order to improve the problem that the height of the combustion unit is increased, a method of discharging air outside the gas toward the inside of the combustion unit from the side of the combustion unit has been applied, but this side injection method is simple to lower the overall height of the combustion unit. Since the inlet of the mixed gas is formed on the side of the combustion unit, the detailed configuration in which the gas and the air are mixed is composed of a structure that is separated from each other in the vertical direction with respect to the horizontal plane of the combustion unit, the height of the combustion unit is more than a predetermined level.

This configuration is to ensure that the mixed gas is mixed smoothly in the combustion unit, the gas injected from the mixing tube was essentially provided to allow the combustion in the inner space of the narrow burner.

If the combustion unit does not have a predetermined size or more, the amount of air introduced with the gas is insufficient, so that the gas and the air cannot be smoothly mixed inside the combustion unit, resulting in incomplete combustion.

In addition, if the combustion unit does not have a certain size, the flow resistance of the mixed air is increased, it can not be sufficiently mixed, the mixed gas is not uniformly provided.

In addition, the combustion unit may have the same size and increase the combustion efficiency of the gas by reducing the amount of gas introduced into the combustion unit. However, in this case, the amount of heat generated decreases, which is not preferable because it takes a long time to cook food. Can not do it.

On the other hand, the burner system is provided with a burner system for forming the exhaust flow path of the combustion gas generated by the combustion of the mixed gas formed by mixing the gas and air, and the combustion of the gas is formed in the burner system, For the convenience of the user, the combustion units having different heating values are positioned.

That is, a combustion unit having a relatively large calorific value and a combustion unit having a relatively small calorific value are provided.

However, a combustion unit having a relatively large calorific value forms a longer exhaust flow path than a combustion unit having a relatively small calorific value, thereby causing a problem of raising the temperature of the internal space of the heating cooker.

In addition, the combustion unit having a relatively large heat generation amount is located close to the position where the control component for controlling the burner system is mounted, so that a plurality of control components for controlling the burner system by heat emitted from the combustion unit The problem of damage will occur.

When heat damage occurs to the control component for controlling the burner system, a problem occurs that the control component malfunctions. This prevents the user from performing the desired dish.

The problem is that the smaller the size of the heating cooker is expanded to a larger problem, the situation is urgently required a method of preventing thermal damage of the components for control.

The present invention has been proposed to solve the above problems, and proposes a heating cooking apparatus in which a burner system having a relatively large calorific value is shorter than an burner system having a relatively small calorific value.

In addition, the present invention is to propose a heating cooking apparatus in which the burner system having a relatively large heat generation amount is far from the control component for controlling the burner system.

In addition, the present invention proposes a heating cooking apparatus in which an air flow path of a burner system having a relatively large heat generation amount and an air flow path of a burner system having a relatively small heat generation amount are formed differently.

The heating cooking apparatus according to the present invention for providing a heating cooking apparatus as described above, the case; A ceramic plate covering an upper surface of the case; And a plurality of burner systems having different calorific values in the internal space formed by the ceramic plate and the case, wherein the burner system exhausts the burner system in which an exhaust passage of the burner system having a relatively large calorific value has a relatively small calorific value. It is formed shorter than the flow path.

In another aspect the heating cooking apparatus according to the present invention, the case; A ceramic plate covering an upper surface of the case; And a plurality of burner systems having different calorific values in the internal space formed by the ceramic plate and the case, and a burner system having a large calorific value has the same flow direction as the flow direction of the introduced fluid and the discharged fluid. The burner system having a small calorific value is formed in a different direction from the flow direction of the incoming fluid and the flow direction of the discharged fluid.

In another aspect, the heating cooking apparatus according to the present invention, the case; A ceramic plate covering an upper surface of the case; And a burner system formed in the interior space of the ceramic plate and the case, wherein the region where the food is heated by the burner system and a relatively low temperature region are formed in comparison with the region.

According to the present invention, while reducing the overall size of the heating cooker, in particular, the height of the heating cooker, it is possible to implement the same amount of heat, and to increase the internal temperature of the heating cooker, it is easy to use You can get the advantage of being maximized. Such a fundamental effect of the present invention can be achieved by reducing the flow resistance of the high heat generating portion while the exhaust passage of the relatively high heat generating portion of the heating cooking apparatus is formed short.

Hereinafter, with reference to the accompanying drawings will be described a specific embodiment of the present invention.

1 is a perspective view showing the external appearance of the heating cooking apparatus according to the present invention, Figure 2 is an exploded perspective view showing the internal configuration of the heating cooking apparatus according to the present invention. In addition, Figure 3 is a plan view showing a state in which the ceramic plate of the heating cooking apparatus according to the present invention is removed.

Looking at the heating cooking apparatus according to the present invention with reference to the accompanying drawings, the heating cooking apparatus protects the lower side while forming the overall appearance of the lower side and the upper surface of the hexahedral-shaped case 200 and seated on the upper surface of the case And a ceramic plate 100 to support a container containing food, and a top frame 120 to cover an edge of the ceramic plate 100.

In addition, as an additional external configuration of the heating cooking apparatus, an exhaust grill 140 formed at the rear side of the ceramic plate 100 and exhausting combustion gas is formed, and formed at a substantially front portion of the ceramic plate 100 to prevent combustion of the gas. There is an operation switch 160 for controlling the on / off. The exhaust grill 140 and the operation switch 160 may be changed in various positions or shapes, but it is obvious that an exhaust part through which combustion gas is discharged and a switch for controlling on / off combustion of gas are additionally provided. .

In the internal space defined by the ceramic plate 100 and the case 200, a plurality of components for combustion and exhaust of gas are accommodated, and the internal structure thereof will be described below.

First, three burner ports 210 are provided in the inner space of the case 200 to provide a space in which gas and air are sufficiently mixed to burn uniformly. Mixing pipe unit 220 is placed on each side of the burner port 210 to supply gas and air through the side of burner port 210.

Then, a nozzle unit (not shown) is provided in a state where a predetermined interval is maintained with the inlet portion of the mixing tube unit 220 to inject the gas at a high pressure toward the inlet of the mixing tube unit 220.

The burner frame 230 is placed above the burner port 210, and the burner frame 230 supports the position of the burner port 210 and exhausts the exhaust flow path of the combustion gas generated on the glowing plate 240. Will be provided. An exhaust unit 260 is formed at the rear of the burner frame 230 to allow combustion gas to be discharged to an external space, and the exhaust grill 140 is disposed above the exhaust unit 260.

The upper surface of the burner port 210 is formed to be opened, the glowing plate 240 is placed on the opened upper surface, the glowing plate 240 is heated by the high heat generated when the gas and air is burned. When the glowing plate 240 is heated, radiant energy of a frequency band corresponding to the physical properties of the glowing plate 240 is radiated.

The radiant energy of the glowing plate 240 includes at least the frequency of the visible light band, the user can recognize that the heating cooking apparatus of the present invention is in operation by the visible light. Of course, the food is heated by the red plate 240, it is natural that the food is heated by the heat plate 240 is also heated by the conductive heat of the ceramic plate (100).

Hereinafter, a structure in which gas is supplied to the inner space of the case 200 will be described.

Gas is supplied from the outside to the inside of the heating cooking equipment through the main supply pipe 250, the gas is directed to each burner system by the gas valve 252 is controlled by the operation switch 160, the respective nozzles Supplied to the unit.

The gas supplied to the nozzle unit is injected at a high pressure toward the inlet of the mixing tube unit 220 by the nozzle unit, and at this time, the gas injected toward the inlet of the mixing tube unit 220 is a high speed, and according to Bernoulli theorem. A low pressure atmosphere is formed in the space adjacent the inlet of the mixing pipe unit 220.

Therefore, outside air is also introduced into the mixing tube unit 220 together, and the fluid passing through the mixing tube unit 220 forms a mixed gas while gas and air are mixed. The mixed gas formed while passing through the mixing tube unit 220 flows into the inner space of the burner port 210 and then is secondaryly mixed and combusted on the glowing plate 240.

In addition, the heat of the glowing plate 240 is formed in red by the combustion heat generated while the mixed gas is burned, and radiant heat is generated in the glowing plate 240 formed in red.

Here, the glowing plate 240 is formed in the shape of a mesh in which a number of fine holes are processed innumerably, and these holes are burned while gas and air pass. The combustion gas generated while the gas is burned is guided along the exhaust flow path provided by the burner frame 230 and discharged to the external space through the exhaust grill 140. As such, the exhaust passage may be defined as a space between the lower portion of the ceramic plate 100 and the upper portion of the burner frame 230.

A plurality of burner systems having different heating values are formed in the inner space of the case 200. Hereinafter, the burner system provided in the inner space of the case 200 will be described.

In the inner space of the case 200, two burner ports 210 having a relatively large heat generation amount are disposed on both sides of a central portion, and one having a relatively small heat generation amount between two relatively large burner ports 210. The burner port 210 is provided. Of course, the burner port 210 having a relatively large heat generation amount is formed to have a different heat generation, it is possible to maximize the convenience of commercial use. Therefore, the user places the container containing the food corresponding to the calorific value of each burner pot 210 to cook the food.

In addition, one low heat burner system having a relatively small amount of heat generated at the center of the inner space of the case 200 is provided with the burner port 210 having a relatively small size, and the burner port 210 is forward from the rear. The gas is supplied toward the secondary to completely mix the gas and the air, and is burned on the glowing plate 240, and then the combustion gas flows backward.

Therefore, an exhaust port that is combusted at the inlet side and the burner port 210 of the mixing pipe unit 220 into which gas and air are introduced into the internal space of the burner port 210 having a relatively small heat generation amount is discharged. In the same direction, that is, located behind the burner port 210.

The burner system having a relatively low calorific value is formed in a different direction in which gas and air flow. In detail, the flow direction of the gas and air flowing into the burner system having a relatively low heat generation flows toward the front of the heating cooker, and the combustion gas generated while the gas and the air burns toward the rear of the heating cooker. By flowing, the flow direction of the incoming fluid and the flow direction of the discharged fluid are formed in different directions.

On the contrary, a burner system placed on both sides of the inner space of the case 200, that is, two burners having relatively large calorific values while being placed on both sides of the burner system having a small amount of heat generated in the inner space of the case 200. Port 210 is a gas and air is supplied to the internal space of the burner port 210 from the front of the heating cooker toward the rear to be a mixture of gas and air in the interior of the burner port 210 secondary, gas Combustion gas generated while and air is mixed and then burned on the glowing plate 240 flows to the rear of the heating cooker and is discharged to the outside space.

Therefore, an exhaust port that is combusted at the inlet side and the burner port 210 of the mixing pipe unit 220 into which the gas and air are introduced into the internal space of the burner port 210 having a relatively large heat generation amount is discharged. In other directions, that is, in front of and behind the burner port 210, respectively.

Therefore, the burner system having a relatively large heat generation amount is formed in the same direction in which gas and air flow. In detail, the flow direction of the gas and air flowing into the burner system having a relatively high heat generation flows toward the rear of the heating cooker, and the combustion gas generated while the gas and the air are burned also goes toward the rear of the heating cooker. As it flows, the flow direction of the incoming fluid and the flow direction of the discharged fluid are formed in the same direction.

The arrangement of the burner port 210 as described above is for implementing an optimal burner system arrangement.

In the burner system arranged as described above, the flow path resistance of the burner system having a relatively high heat generation amount has a flow path resistance smaller than that of the burner system having a relatively low heat generation amount.

This is because in the burner system having a relatively large heat generation amount, the flow direction of the entire fluid flows in one direction, in detail, from the front to the rear of the heating cooker, thereby reducing the flow path resistance.

At this time, in the burner system having a relatively small heat generation amount, the flow direction of the entire fluid flows in two directions, in detail, from the rear to the front to form a flow path discharged from the front to the rear, but the flow resistance increases. Even if it increases, the sufficient flow path is secured so that the lowering of the amount of heat generated by the flow path resistance does not appear.

Hereinafter, a burner system of a heating cooking appliance according to the present invention will be described. The burner system of the heating cooking apparatus according to the present invention increases the amount of air compared to the gas, hereinafter referred to as the air ratio, while reducing the height of the combustion unit, and reduces the flow resistance of the mixed gas in which the gas and air are mixed. It is provided in a characteristic structure.

The burner port 210 is provided in the inner space of the case 200, and the mixing pipe unit 220 is disposed at the side of the burner port 210. The nozzle unit for discharging the gas at a high pressure to the inlet of the mixing tube unit 220 in a state where a predetermined distance from the mixing tube unit 220 is maintained.

Here, the mixing pipe unit 220 is aligned with the opening 212 formed on the side of the burner port 210. Since the plurality of mixing tubes 222 and the openings 212 provided in the mixing tube unit 220 are provided in parallel with each other, the amount of air introduced with the gas is maximum. The alignment state of the mixing tube unit 220 and the opening 212 will be described later.

The height of the opening 212 is substantially the same as or slightly smaller than the height of the burner port 210. In detail, the opening 212 is formed in a circular shape when viewed from the mixing tube unit 220 in the direction of extension of the mixing tube 222. The diameter of the opening 212 is provided to be substantially the same as the up and down height of the space in which the gas and air can be sufficiently mixed in the internal space of the burner port 210 so that the mixed gas mixed with gas and air to the maximum To spread in the internal space of the burner port (210).

As such, the heights of the openings 212 and the burner port 210 are substantially the same, so that the diffusion of gas and air in the inner space of the burner port 210 can be promoted, and the height of the burner port 210 is maximized. Can be lowered.

In addition, the mixing pipe 222 having a plurality of the mixing pipe unit 220 is provided in the form of a nozzle that is initially reduced in cross-sectional area with the inlet of the mixing pipe 222 as a starting point, and formed in a minimum cross-sectional area. After passing through the part, the cross section is provided in the form of a diffuser.

In addition, it is preferable in terms of reducing the flow resistance of the fluid that the mutually continuous increase of the diffuser portion of the mixing tube 222 and the cross-sectional area portion of the opening 212 is preferable. That is, the diffusion angles of the opening 212 and the mixing tube 222 are preferably the same.

On the other hand, as described above, the mixing pipe unit 220 is coupled to one side of the burner port 210. The mixing pipe unit 220 is provided with a plurality of mixing pipes 222, and the burner port 210 has a plurality of openings 212 aligned with the mixing pipe 222. Then, the nozzle unit is located at a predetermined interval apart from the inlet of the mixing tube unit 220.

In addition, the nozzle unit is formed in a straight line, because the overall shape of the mixing pipe unit 220 is arranged in a straight line. As a result, the arrangement of the burner system may be more compact.

Since the plurality of the mixing pipes 222 are horizontally provided side by side in the mixing pipe unit 220, the inflow amount of the gas introduced together with the gas injected from the nozzle unit, that is, the air ratio can be increased. do. In detail, a plurality of mixing pipes 222 are provided so that a large amount of air is sucked together with the gas through each of the mixing pipes 222.

As such, the intake of a large amount of air may be easily understood by comparing with the case where the gas is sucked through the single mixing tube 222. For example, when the gas is sucked through the single mixing tube 222, a low pressure atmosphere is formed around the single mixing tube 222 so that air flows into the mixing tube 222, but a plurality of mixing tubes ( When the gas is sucked into the 222, the space into which the air is introduced is increased, so that the amount of air introduced through the mixing pipe 222 is increased by adding up the total air inflow amount.

In addition, the mixing pipe unit 220 is provided with a plurality of the mixing pipe 222, are provided side by side at the same height. Of course, the center may be shifted by a predetermined length in the vertical direction, but is substantially provided side by side. As the mixing pipe 222 is provided side by side, the mixed gas flowing into the internal space of the burner port 210 collides with each other, thereby increasing the generation of turbulence, and the gas and air mixing are enhanced to increase the combustion efficiency of the gas. Is improved. The range in which the vertical height of the mixing tube 222 is limited is because the height in which the mixing tube 222 can be placed is limited to the range in which the opening 212 can be formed.

On the other hand, the direction in which the mixing pipe 212 is preferably extended in the same direction with each other. In other words, it is preferable that the extension lines of the mixing tubes 222 do not meet each other. By doing so, as described above, the generation of turbulence between the mixed gases flowing out of the different mixing tubes 222 inside the burner port 210 may be enhanced, and the manufacturing process of the mixing tube unit 220 is simple. It is possible to obtain an advantage that the mounting of the nozzle unit aligned with the mixing tube unit 220 becomes simple and convenient.

In addition, the mixing tube 222 provided to the mixing tube unit 220 is five as shown in the figure, which is according to a number of experiments. Experiments show that in the process of increasing the number of mixing tubes 222 from one to five, the increase in the air ratio increases rapidly, and after the five, the number is significantly reduced. Therefore, the efficiency of the air ratio increases slightly compared to the manufacturing cost by increasing the number of mixing tubes 222 by one, so that the number of mixing tubes 222 is preferably provided in five.

In this case, the range in which the mixing tube 222 is disposed is equally distributed on the side of the burner port 210, and the mixing tube 222 disposed at the last end is substantially the burner port 210. It is more preferable in terms of mixing efficiency of the gas and air flowing into the burner port 210 is disposed at the end of the entire diameter of the. This is because turbulence is smoothly generated in the internal space of the burner port 210.

According to the flow of gas and air flowing in different directions along the tangential direction on the inner surface of the burner port 210, a point where the gas and air collide with each other occurs. In this way, a collision point of the mixed gas is generated, a lot of turbulence is generated, the mixed gas is spread throughout the burner port 210 by this turbulence, the gas uniformly throughout the burner port 210 Since the air is mixed with the burner port 210, even if the height of the burner port 210 is lowered, it is possible to produce a uniform mixed gas and to achieve a uniform combustion performance later.

Hereinafter, the burner system will be described in terms of the exhaust passage.

As described above, a plurality of burner systems having different heating values are provided in the inner space of the case 200. Such a burner system is provided with a burner system having a relatively large amount of heat and a burner system having a relatively small amount of heat.

In the present invention, for example, it is described that three burner systems are provided, but the calorific value of the three burner systems is formed differently. Therefore, it is divided into a high heat generation burner system having a relatively large heat generation amount and a low heat generation burner system having a relatively small heat generation amount.

The rear side of the ceramic plate 100 covering the upper surface of the case 200 is provided with an exhaust grill 140 for discharging the combustion gas generated while the gas is burning, the high heat burner system having a relatively large heat generation amount is It is located close to the exhaust grill 140.

In detail, the center of the burner port 210 provided in the burner system having a relatively high heat generation amount is located closer to the exhaust grill 140 than the center of the burner port 210 provided in the burner system having a relatively low heat generation amount. It is provided to guide the burner frame 230 to form a short flow distance of the combustion gas is exhausted through the exhaust grill 140.

This means that the amount of combustion gas generated in the burner system having a relatively high calorific value is greater than the amount of combustion gas generated in the burner system having a relatively high calorific value, and the flow distance at which a large amount of the combustion gas flows. This is to prevent the internal temperature of the case 200 from rising by shortening the time that the potential heat of the combustion gas is transferred to the inside of the case 200 by forming the short.

In addition, the combustion gas of the burner system having a relatively large calorific value in which a large amount of combustion gas is generated can be obtained the advantage that the flow of air is smoothed by the flow distance is shortened.

At this time, the exhaust flow path through which the combustion gas generated in the burner system flows is provided at a position opposite to the space where the control component for controlling the burner system is located. As such, the combustion gas generated in the burner system is formed in a direction opposite to the space where the control component is located, thereby preventing the potential heat of the combustion gas from being transferred to the control component and preventing thermal damage of the control component. You can do it.

On the other hand, the burner system proposed in the present invention is provided with the burner port 210 is provided with a circular depression so that the gas and air is sucked through the mixing pipe unit 220, the gas and air sucked is faithfully provided The burner frame 230 is provided above the burner port 210 and the mixing tube unit 220 to guide the flow of the combustion gas generated by the combustion of the gas.

Five mixing tubes 222 are provided in the mixing tube unit 220 of the burner system. Therefore, when the mixing tube unit 220 formed integrally is fastened to the burner port 210, the five mixing tubes 222 are aligned at once.

In addition, there is a concern about misalignment between the mixing tube 222 and the opening 212 and a concern about misalignment between the mixing tube 222 and the nozzle unit, and the distance between the inlet of the mixing tube 222 and the nozzle unit There is an advantage that there is no fear that the amount of gas and air inflow varies by mixing tube 222.

This advantage can be more clearly understood as compared to the imaginary case where the plurality of mixing pipes 222 are fastened to the nozzle unit to be aligned with each of the openings 212, respectively.

The advantage of the integrated mixing tube unit 220 as described above is that even if the center of the discharge port from which the gas is discharged from the nozzle unit is slightly displaced from the inlet of the mixing tube, the space that the low pressure caused by the injection gas may have significantly reduced. This is more pronounced with reference to this, which will drastically reduce the efficiency with which air is introduced.

In this way, the mixing pipe unit 220 is fastened to the burner port 210, so that the production and assembly are efficiently performed, the adhesion between the mixing pipe unit 220 and the burner port 210 is increased, and the defective rate is lowered. The cost of materials is reduced.

In the above manner, each of the mixing pipes 222 is fastened to the mixing pipe unit 220 in a manner in which the plurality of mixing pipes 222 are supported by a predetermined jig to the mixing pipe unit 220. A fastening method may be used, and in another case, the plurality of mixing tubes 222 may be provided integrally with the mixing tube unit 220.

While the mixing pipe 222 is fastened to the mixing pipe unit 220 by a predetermined jig, the plurality of mixing pipes 222 inlets may be aligned in a line, so that the nozzle unit and the plurality of mixing pipes ( 222) The distance between the inlets may remain the same.

Hereinafter, the air flow of the burner system will be described.

Each burner system configured as described above is provided with the burner port 210, and each of the mixing pipe units 220 for guiding gas and air from the side of the burner port 210 is provided.

In addition, the high heat generation burner system having a relatively high calorific value has the same flow direction as the flow direction of the gas and air and the combustion gas generated when the gas is combusted. The flow direction of the air and the flow direction of the combustion gas generated when the gas is burned have a different direction.

In detail, the mixing tube unit 220 provided in the high heat generation burner system having a relatively large heat generation amount is positioned in front of the center of the burner port 210. Preferably, the gas and air are positioned in front of the burner port 210 to be introduced into the burner port 210.

In addition, the exhaust grill 140 through which the combustion gas generated while the gas is combusted is disposed at the rear side of the ceramic plate 100, and the burner frame 230 for guiding the flow of the combustion gas is a burner port ( The combustion gas flows to the rear of 210.

Therefore, in the high heat burner system, the mixing pipe unit 220 is placed in front of the burner port 210, and the gas and air introduced into the burner port 210 by the mixing pipe unit 220 are rearward from the front. Gas and air flowing into the burner port 210 are mixed and burned while passing through the glowing plate 240 placed above the burner port 210, and the gas is burned. Combustion gas flows from the front of the burner frame 230 to the rear provided above the burner port 210.

That is, in the high heat generation burner system, the combustion gas flows in the same direction as the gas and air flow.

On the other hand, in the burner system having a relatively small heat generation amount, the flow direction in which the gas and air flow and the flow direction of the combustion gas generated when the gas is burned have different directions.

In detail, the mixing tube unit 220 for guiding gas and air to the burner port 210 provided in the low heat burner system having a relatively low heat generation amount is placed to be located behind the center of the burner port 210. Preferably, the gas and the air may be positioned in the burner port 210 immediately after the burner port 210.

In addition, the exhaust grill 140 through which the combustion gas generated while the gas is combusted is disposed at the rear side of the ceramic plate 100, and the burner frame 230 for guiding the flow of the combustion gas is a burner port ( The combustion gas flows to the rear of 210.

Therefore, in the low heat burner system, the mixing pipe unit 220 is placed at the rear of the burner port 210, and the gas and air introduced into the burner port 210 by the mixing pipe unit 220 are disposed at the rear. The gas flows forward, and gas and air introduced into the burner port 210 are mixed and burned while passing through the glowing plate 240 placed above the burner port 210. The combustion gas generated while the gas is burned is guided by the burner frame 230 provided above the burner port 210 and flows from the front to the rear.

In this way, in the low heat burner system, the direction in which the gas and air flow and the direction in which the combustion gas flows become opposite directions.

Looking at the air flow from another side, in a high heat generation burner system having a relatively large heat generation amount, the flow direction in which gas and air are introduced is forward of the burner port 210, and the flow direction in which combustion gas is discharged is burner port 210. ), The inflow direction of the fluid and the exhaust direction of the fluid are formed in different directions.

In addition, in the low heat burner system having a relatively small heat generation amount, the flow direction in which gas and air are introduced is the rear of the burner port 210, and the flow direction in which the combustion gas is discharged is the rear of the burner port 210. The inflow direction and the exhaust direction of the fluid are formed in the same direction with each other.

On the other hand, referring to Figure 5 the heating cooking apparatus according to the present invention from another side, the case 200, the ceramic plate 100 covering the upper surface of the case 200 is provided, the ceramic plate 100 And a burner system formed in an inner space defined by the case 200, and a relatively low temperature region is formed in the ceramic plate 100.

In the internal space defined by the ceramic plate 100 and the case 200, a burner system for heating a container containing food placed on the upper side of the ceramic plate 100 is formed, and the burner system has a high heat generation having a relatively high heat generation amount. It is composed of a burner system and a low heat burner system having a relatively small heat generation amount.

The burner system is provided with a burner port 210 for providing a combustion space of gas and air, and the mixing pipe unit 220 for supplying gas and air to the burner port 210 on the side of the burner port 210. ) Is provided.

In the burner system configured as described above, the calorific value of each of the burner ports 210 provided therein is different to cook food using the burner port 210 having a calorific value corresponding to the amount or size of food to be cooked by the user. .

On the other hand, the burner port 210 provided in the burner system having a relatively large heat generation amount is placed on both sides of the inner space of the case 200, and the burner port 210 provided in the burner system having a relatively small heat generation amount therebetween. ) Is placed. As such, when the burner system is located, a relatively low temperature region is formed in the ceramic plate 100 between each burner system.

The heat generated in the burner system generates a certain amount of heat on the ceramic plate 100 due to the potential heat around the burner port 210, thereby warming the container containing the cooked food by the heat. Relative low temperature areas are formed that can be maintained.

This is to prevent the food from cooling quickly by heating the container containing the food that has been cooked by the relative low temperature region to allow the user to ingest the warm food for a certain time.

The spirit of the present invention is not limited to the described embodiments, and those skilled in the art that understand the spirit of the present invention can easily suggest other embodiments by adding, changing, and deleting components within the scope of the same idea, Various embodiments may be proposed by partially merging the embodiments, but they may also be included in the spirit of the present invention.

According to the heating cooking apparatus according to the present invention as described above, the combustion efficiency of the gas in the burner system can be improved, the flow resistance of the gas and air is reduced, the air ratio can be obtained.

In addition, the overall size of the heating cooker, in particular the height of the burner system is reduced, it is possible to obtain the ease of installation, saving material costs, ease of use. Of course, this effect is an advantage that is generated in comparison with a heating cooking apparatus that can obtain a comparable heating value.

In addition, a high heat burner system having a relatively high heat generation amount and a low heat burner system having a relatively low heat generation amount are formed, and the exhaust passage of the high heat burner system is shorter than the exhaust flow path of the low heat burner system, so that combustion gas is smoothly discharged There is this.

Furthermore, the high heat burner system is farther away from the space in which the control component for controlling the burner system is located than the low heat burner system, which reduces the heat transferred to the control component. There is an effect that is prevented.

The thermal damage of the control part is prevented to prevent the malfunction of the control part, and if the malfunction of the control part is prevented, the dish desired by the user can be cooked in the desired way, which greatly improves the reliability of the product. Improved reliability of the product is to maximize the ease of use.

In addition, as the thermal damage of the electrical components is prevented, there is an effect of reducing the maintenance cost of the product, there is an effect of reducing the service cost.
