In addition, in order to ensure airtightness in the casing, a cover (door) is provided at the opening. Here, when the air cleaner includes a humidifying unit, it is necessary to provide an opening for attaching and detaching the humidifying unit in addition to the opening for attaching and detaching the air purifying filter. From the viewpoint of ensuring airtightness, it is not preferable to increase the number of openings.

A technical problem of the present invention is to provide an air cleaner capable of easily ensuring airtightness in a casing by suppressing the number of openings.

Technical solutions adopted to solve technical problems

The air purifier of the first technical solution of the present invention includes an air purifying filter, a humidifying unit, a blower fan and a casing. The air purification filter removes dust contained in the air. The humidification unit vaporizes the supplied water to humidify the air. The blower fan blows air toward the air purification filter and the humidification unit. The casing accommodates the humidifying unit, the air purification filter and the blower fan. The housing has openings for attaching and detaching the humidification unit. The humidification units are arranged in a row on the downstream side of the air purification filter in the detachment direction of the air purification filter. The opening allows the air cleaning filter to be removed after the humidification unit has been removed.

In the air cleaner according to the first aspect of the present invention, the humidification units are arranged in a row on the downstream side of the air cleaning filter in the detachment direction of the air cleaning filter. In addition, the opening for attaching and detaching the humidifying unit is used for detaching the air cleaning filter after detaching the humidifying unit.

Thereby, one opening can be used for both the attachment and detachment of the air purification filter and the attachment and detachment of the air purification filter. As a result, the number of openings can be suppressed.

The air cleaner of the second technical solution of the present invention is based on the air cleaner of the first technical solution, and the removal direction is the thickness direction of the air cleaning filter.

In the air cleaner according to the second aspect of the present invention, the detachment direction is the thickness direction of the air cleaning filter. That is, when detaching the humidifying unit, a space for detaching the air purifying filter is formed in the thickness direction of the air purifying filter.

Thereby, the air purification filter can be easily removed.

The air cleaner of the third technical solution of the present invention is based on the air cleaner of the first technical solution or the second technical solution, and further includes a sealing element. The sealing element seals the gap between the air cleaning filter and the housing. The sealing member is provided on the upstream side of the air cleaning filter in the detachment direction.

In the air cleaner according to the third aspect of the present invention, a sealing member for sealing a gap between the air cleaning filter and the housing is provided on the upstream side in the detachment direction of the air cleaning filter.

Thereby, rattling of the air purification filter in the casing can be suppressed.

An air cleaner according to a fourth aspect of the present invention is the air cleaner according to any one of the first aspect to the third aspect, wherein the humidification unit has a box, a tray, and a humidification filter. The tank stores water. The tray receives water from the tank. The humidification filter contains water supplied from the tray, and vaporizes the water to humidify the air.

In the air cleaner according to claim 4 of the present invention, the humidification unit has a tank, a tray, and a humidification filter. In addition, the air purification filter can be removed through the opening after the case, the tray, and the humidification filter are removed from the case.

Thereby, a space sufficient for removing the air cleaning filter can be secured above the air cleaning filter.

The air purifier of the fifth technical solution of the present invention is based on the air purifier of any one of the first technical solution to the third technical solution, and the humidifying unit is arranged above the air cleaning filter in the casing. The humidification unit has a movement restriction unit. The movement restricting part restricts upward movement of the air purifying filter in a state where the humidifying unit and the air purifying filter are mounted in the housing.

Here, since the humidification unit restricts the upward movement of the air purification filter, it is possible to prevent the air purification filter from floating up with a simple structure without providing a dedicated member for restricting the movement of the air purification filter. In addition, the number of parts can be suppressed compared to the case of providing a dedicated member for restricting movement.

An air cleaner according to a sixth technical aspect of the present invention is based on the air cleaner according to the fifth technical aspect, and further includes a filter case that accommodates at least a part of the air purification filter. The filter housing includes an airflow guide that guides air flowing through the air purification filter toward the humidification unit. The movement restricting portion is in contact with the upper portion of the airflow guide.

Here, the upward movement of the air purification filter is restricted by contacting the upper part of the air flow guide of the filter case with the movement restriction part of the humidification unit, so that the air purification filter can be prevented from floating up with a simple structure. In addition, since the airflow guide and the movement restricting part are in a contact relationship, air is less likely to flow between the airflow guide and the movement restricting part, and the air passing through the air purification filter can be prevented from being guided along an undesired path.

The air purifier of the seventh technical solution of the present invention is based on the air purifier of the sixth technical solution, and the air cleaning filter includes a first filter and a second filter arranged below the first filter. The filter housing accommodates the first filter. When the first filter housed in the filter case is mounted toward the housing, the filter case slides on the upper surface of the second filter. After the first filter housed in the filter case is attached to the housing, the filter case comes into contact with the upper surface of the second filter.

Here, when the case of the first filter is attached, the filter case in which the first filter is accommodated slides on the upper surface of the second filter, so that the first filter is easily attached to the case. In addition, after the first filter is installed, the filter housing is in contact with the upper surface of the second filter, thereby restricting the second filter from moving upward.

The air cleaner according to the eighth technical aspect of the present invention is based on the air cleaner according to the seventh technical aspect, and the housing side convex portion or the housing side concave portion is formed on the filter housing. The case is formed with a case-side concave portion or a case-side convex portion, which is formed on the filter when the first filter housed in the filter case is attached to the case. The case side convex part or the case side concave part of the device case fits.

Here, since one of the convex part and the recessed part to be fitted with each other is respectively provided in the case and the filter case, it becomes easy to attach the 1st filter accommodated in the filter case to a predetermined position.

In addition, when the filter case is slid on the upper surface of the second filter, that is, when the filter case is guided by the upper surface of the second filter, it is easy to fit the convex part and the concave part. However, in the absence of the second filter (in the case where the filter housing cannot be slid on the upper surface of the second filter), it is difficult to align the protrusions and the recesses so that the protrusions and recesses fit together. . That is, here, in the absence of the second filter, it is difficult to install the first filter. Therefore, it is easy to prevent forgetting to install the second filter.

The air purifier of the ninth technical solution of the present invention is based on the air purifier of the eighth technical solution, and further includes a filter detection sensor that detects whether the first filter is installed in the casing.

Here, by providing the filter detection sensor, it is possible to prevent forgetting to attach the first filter.

In addition, the air cleaner adopts a structure in which it is difficult to install the first filter in the absence of the second filter. Therefore, it is possible to check whether the air purification filter is forgotten to be installed only by detecting the presence or absence of the first filter. Check the device as a whole.

Invention effect

In the air cleaner according to the first aspect of the present invention, one opening can be used for both attachment and detachment of the air purification filter and attachment and detachment of the air purification filter. As a result, the number of openings can be suppressed.

In the air cleaner according to the second aspect of the present invention, the air cleaning filter can be easily detached.

In the air cleaner according to the third aspect of the present invention, shaking of the air cleaner in the casing can be suppressed.

In the air cleaner according to the fourth aspect of the present invention, a space sufficient for detaching the air cleaning filter can be secured above the air cleaning filter.

In the air cleaner according to the fifth technical solution of the present invention, the humidification unit restricts the upward movement of the air purification filter. Therefore, it is not necessary to provide a special member for restricting the movement of the air purification filter, and it can be cleaned with a simple structure. I prevent the rising of the air cleaning filter.

In the air cleaner according to the sixth aspect of the present invention, the air cleaner filter can be prevented from floating up with a simple structure.

The dust collection filter 21 removes dust contained in the air. The deodorizing filter 22 absorbs unpleasant odor components contained in the air. The dust collecting filter 21 and the deodorizing filter 22 are sequentially arranged in the air cleaning chamber R2 from the upstream side in the flow direction of the air. Specifically, the dust collecting filter 21 and the deodorizing filter 22 are arranged along the respective thickness directions. The thickness directions of the dust collecting filter 21 and the deodorizing filter 22 are aligned with the flow direction f2 of the air flowing through the air cleaning chamber R2. In other words, the air purification filter 20 is arranged in a direction perpendicular to the air flow direction f2.

As described above, the air purification filter 20 is disposed on the flange portion 11d formed inside the housing 11. As shown in FIG. In other words, the air cleaning filter 20 is held by the flange portion 11d. A sealing member 11e is provided between the air purification filter 20 and the flange portion 11d. The sealing member 11e is arranged to lie on the flange portion 11d. Specifically, the sealing member 11e is arranged along the surface of the flange portion 11d.

The flange portion 11d and the sealing member 11e are arranged on the upstream side of the air purification filter 20 in the air flow direction. In other words, the sealing element is arranged on the upstream side of the air cleaning filter 20 in the detachment direction of the air cleaning filter 20 . When the air is transported from the air supply chamber R1 to the air purification chamber R2, the sealing element ensures the airtightness between the air purification filter 20 and the casing 11 .

At the time of maintenance, the air cleaning filter 20 is attached and detached through the opening 15 (see FIG. 7 ). Specifically, after the humidifying unit 30 described later is detached through the opening 15, the air purification filter 20 is moved using the space formed in the housing 11 (that is, the humidifying chamber R3), and then attached and detached through the opening 15. . Specifically, the air cleaning filter 20 is moved in the thickness direction of the air cleaning filter 20 to be removed from the casing 11 . That is, the thickness direction of the air-purifying filter 20 coincides with the detachment direction (attachment-detachment direction) of the air-purification filter 20 . In addition, the detachment direction of the air cleaning filter 20 matches the flow direction of the air in the air cleaning chamber R2. In other words, dust collecting filter 21 and deodorizing filter 22 are separated from flange portion 11 d by moving along the flow direction of air in air cleaning chamber R2 , and are removed from casing 11 .

That is, the humidifying unit 30 is arranged at an upper position in the casing 11 . When the humidifying unit 30 is detached from the casing 11 , a large space can be formed at an upper position inside the casing 11 . Specifically, when the humidification unit 30 is detached from the casing 11, a space in which the air purification filter 20 can move is formed in the humidification chamber R3. In other words, when the humidifying unit 30 is detached from the casing 11 , a space is formed above the air purification chamber R2 as a movement path when the air purification filter 20 is detached. In addition, the air cleaning filter 20 is moved in the thickness direction of the air cleaning filter 20 (direction perpendicular to the air cleaning filter 20 ), and is removed from the flange portion 11d.

As shown in FIGS. 5 and 6 , the humidifying unit 30 is mainly composed of a box 31 , a tray 32 , and a plurality of humidifying elements 33 .

A water supply valve (not shown) is attached to the water injection port 31a. The water supply valve is a general structure that uses a spring to press the valve core to the valve port. Therefore, here, a detailed description of the water supply valve is omitted.

The box 31 is placed on the box support portion 32a of the tray 32 described later when used (see FIGS. 4 and 6 ). Specifically, the tank 31 is attached to the tray 32 so that the water supply valve is located below. The tank 31 is pressed against the push-in pin of the tray 32 with the water supply valve directed vertically downward. Thereby, the push-in pin utilizes the weight of the box 31 itself to open the water supply valve.

As shown in FIGS. 2 and 3 , the box 31 is disposed in the vicinity of the blowout port 11 b inside the casing 11 . In addition, as shown in FIG. 4 , the box 31 is disposed at the center in the left-right direction within the casing 11 . Moreover, as mentioned above, the side surface of the front side of the box 31 is attached to the door 11c.

As shown in FIG. 5 , a plurality of humidifying elements 33 described later are arranged on both sides in the width direction of the box 31 . In other words, the tank 31 is arranged adjacent to the plurality of humidification elements 33 . Specifically, the box 31 is disposed in a form that partially covers a space between a pair of humidifying elements 33 disposed facing each other. In other words, the tank 31 is partially inserted into the space sandwiched by the pair of humidifying elements 33 .

As shown in FIG. 6, case 31 has a plurality of outer surfaces. The plurality of outer surfaces include a rear vertical surface F1, a lateral vertical surface F2, a curved surface F3, and a lateral inclined surface F4.

The rear vertical surface F1 is a hexagonal surface located near the rear side of the air cleaner 10 . The back-side vertical surface F1 vertically extends in the up-down direction. The rear vertical surface F1 is composed of six sides, namely a pair of upper and lower sides, a pair of left and right sides, and two inclined sides connecting the upper and lower sides and the left and right sides. A pair of upper and lower sides and a pair of left and right sides are respectively parallel. In addition, the dimension d1 of one side on the upper end side of the back side vertical surface F1 is larger than the dimension d2 of one side on the lower end side.

The side vertical surface F2 is a surface extending from both sides in the left-right direction of the back-side vertical surface F1 toward the front side. The side vertical surface F2 is a surface perpendicular to the back side vertical surface F1, and extends vertically in the vertical direction. The side vertical surface F2 has a shape similar to an upside-down L-shape. In FIG. 6 , only the side vertical surface F2 on the right side of the box 31 is shown, but the box 31 also has the side vertical surface F2 on the left side. The side vertical surface F2 has a bilaterally symmetrical shape.

The curved surface F3 is a surface extending downward from the lower end of the back side vertical surface F1. The curved surface F3 is partially curved toward the front side. Specifically, the upper end of the curved surface F3 is located at the same plane position as the rear vertical surface F1, and the lower end of the curved surface is located at a plane position closer to the front side than the rear vertical surface F1. That is, the lower end of the curved surface F3 is located closer to the front side than the planar position of the back side vertical surface F1.

The side inclined surface F4 is a wall surface connecting the side vertical surface F2 and the curved surface F3. In FIG. 6 , only the side inclined surface F4 located on the right side is shown, but the box 31 also has the side inclined surface F4 on the left side. The side inclined surface F4 has a bilaterally symmetrical shape. The side inclined surface F4 is inclined with respect to the flow direction of the air flowing through the air cleaning filter 20 . The flow direction of the air flowing through the air cleaning filter 20 is a direction perpendicular to the thickness direction of the humidifying element 33 (see symbol f3 in FIG. 2 ). Specifically, the side inclined surface F4 inclines toward the center of the width direction of the air cleaner 10 from the front side toward the back side. In other words, the side inclined surface F4 extends from the front side to the back side of the air cleaner 10 from the outer side in the width direction of the air cleaner 10 to the inner side. The inclination angle formed by the side inclined surface F4 and the side vertical surface F2 can be appropriately determined according to the distance from the adjacently arranged humidifying element 33, the size of the space in the humidifying chamber R3, and the like. Specifically, the inclination angle is designed so that the air sent into the humidification chamber R3 is well guided in the thickness direction of the humidification element 33 by flowing along the side inclined surface F4.

The several outer surfaces of the box 31 change the flow direction of the air several times in the humidification chamber R3. Specifically, the case 31 changes the flow direction of air using a plurality of outer surfaces so that the air sent into the humidification chamber R3 passes through the humidification element 33 and is blown out from the air outlet 11b.

More specifically, the side inclined surface F4 causes the air flowing along the box 31 to flow toward the humidifying elements 33 arranged adjacent to both sides of the box 31 . Thereby, the air flow to the humidification element 33 is formed in the humidification chamber R3. That is, the side inclined surface F4 changes the flow of the air which flows through the air purification filter 20 so that it may be guided to the humidification element 33 (refer FIG. 2). In other words, the side inclined surface F4 is inclined with respect to the flow direction (approximately vertical direction) of the air flowing through the air purification filter 20, so that the approximately vertical air flow is guided in the thickness direction of the humidifying element 33 (see FIG. 2 and symbols f3 and f4 in Fig. 3). Then, the air flowing in the thickness direction of the humidifying element 33 (the air flowing through the humidifying element 33 ) is guided to the side vertical surface F2 and blown out from the outlet 11b.

In this way, the box 31 is arranged adjacent to the plurality of humidifying elements 33 so that the air flowing in the direction perpendicular to the thickness direction of the humidifying elements 33 flows through the humidifying elements 33 in a manner of changing the flow direction, and then passes through the humidifying elements 33 along the box 31. The outer surface flows and is blown out from the outlet 11b. That is, by arranging the case 31 adjacent to the plurality of humidification elements 33 , the flow direction of the air passing through the vicinity of the plurality of humidification elements 33 is changed. As a result, the air flowing through the air purification filter 20 changes its flow direction so that it flows through the humidifying element 33 , and then also changes its flow direction so that it flows through the humidifying element 33 and is blown out from the outlet 11 b.

(2－4－2) tray

The tray 32 receives and temporarily stores the water supplied from the tank 31 . In addition, the tray 32 supplies water to a plurality of humidifying elements 33 described later. As shown in FIG. 4 , the tray 32 has a U-like shape when viewed from above. Specifically, the tray 32 includes a portion corresponding to the bottom of the U-shape (base corresponding portion) and portions extending from both sides of the bottom corresponding portion (extended portions) in plan view. The bottom side corresponding portion extends in the width direction (left-right direction) of the air cleaner 10 . The extensions extend in the depth direction (front-rear direction) on both left and right sides of the air cleaner 10 . The tray 32 is arranged directly above the air purification filter 20 described above. Specifically, as described above, the tray 32 is placed on the flange portion 11f.

As shown in FIG. 6, the tray 32 mainly has the tank support part 32a, the water supply part 32b, and the bearing part 32c.

(a) Box support part

The tank support portion 32a supports the tank 31 described above. The tank supporting portion 32a is located at the portion corresponding to the above-mentioned bottom side. A support portion and a press-fit pin (not shown) are provided on the tank support portion 32a. The support portion supports a predetermined portion of the box 31 (corner portion of the box 31 ). The push-in pin contacts with the water supply valve when the box 31 descends due to its own weight, so as to press open the water supply valve. As a result, the water in the tank 31 is supplied to the tank support portion 32a.

Moreover, the handle 32d is provided in the outer wall of the box support part 32a. The user puts a finger in the handle 32d and pulls the box support portion 32a toward the front (front side), thereby pulling the tray 32 out of the casing 11 .

(b) Water Supply Department

The water supply part 32b is a part which supplies the water supplied from the tank 31 to the humidifying element 33. As shown in FIG. Specifically, the water supply part 32b receives the water supplied to the tank support part 32a, and then supplies it to the humidifying element 33. The water supply part 32b is located in the said extension part.

The water supply part 32b and the said tank support part 32a are partitioned by the partition wall which is not shown in figure. Holes are formed in the partition walls. The water supplied from the tank 31 to the tank support part 32a is sent to the water supply part 32b through the hole. That is, the water received by the tank support portion 32 a arranged on the front surface side of the casing 11 is then conveyed in the depth direction on the left and right sides of the casing 11 . The water supply part 32b is filled with water up to a predetermined water level. That is, in the water supply part 32b, in order to immerse the humidification element 33, water is stored to a predetermined water level. As long as there is water in the tank 31, the water stored in the water supply part 32b is automatically adjusted so as to maintain a predetermined water level. In this way, the water received from one tank 31 by one tray 32 is supplied to a plurality of humidification elements 33 .

(c) Bearing part

The bearing part 32c is a part which supports the rotating shaft (rotor rotating shaft) 33d of the humidification element 33 mentioned later. The bearing part 32c is located in the said extension part. The bearing portion 32c is a pair of columns extending vertically upward from the side wall of the water supply portion 32b.

In this embodiment, the water supply part 32b extends on both sides of the width direction of the air cleaner 10, respectively. Therefore, the bearing portions 32c are respectively provided on the water supply portions 32b located on both sides in the width direction. Moreover, the bearing part 32c provided in each water supply part 32b is arrange|positioned at the same planar position in the depth direction. That is, the bearing parts 32c provided in the some water supply part 32b are each arrange|positioned at the position which mutually opposes.

In order to rotatably support the rotor shaft 33d, a U-shaped depression is formed at the upper end of the bearing portion 32c.

(2－4－3) humidification element

The humidifying element 33 vaporizes the supplied water to humidify the air. Specifically, the humidifying element 33 vaporizes the water accumulated in the tray 32 to humidify the air. More specifically, the humidifying element 33 vaporizes the water accumulated in the water supply part 32b to humidify the air.

In this embodiment, a plurality of humidifying elements 33 are used. Specifically, two humidifying elements 33 are used. Two humidifying elements 33 are arranged side by side. Specifically, the two humidifying elements 33 are arranged along the depth direction on both sides of the air cleaner 10 in the left-right direction. As shown in FIG. 2 , FIG. 4 and FIG. 5 , the two humidifying elements 33 are respectively disposed close to both sides of the box 31 . In addition, the two humidification elements 33 are arrange|positioned at the opposing position.

Two humidifying elements 33 are disposed above the tray 32 . Specifically, the humidifying element 33 is arranged above the water supply part 32b of the tray 32 . That is, water is supplied to each of the two humidifying elements 33 by the tank 31 and the tray 32 . In other words, water is supplied to the two humidifying elements 33 by using one common tank 31 and one common tray 32 .

The two humidifying elements 33 are each of the rotary type. Specifically, the humidifying element 33 mainly includes a humidifying filter 33a and a humidifying rotor 33b. The humidification filter 33a is a disk-shaped vaporizer formed of nonwoven fabric. The humidification filter 33a has a filter surface. The two humidifying elements 33 are arranged so that the filter faces of each other face each other. The humidification rotor 33b is a frame that surrounds the outer circumference of the humidification filter 33a to hold the humidification filter 33a. The humidification rotor 33b has a rotor rotating shaft 33d at the center, and has a gear (not shown) on the outer periphery. The first drive part 33e and the second drive part 33f are respectively engaged with gears (see FIG. 5 and FIG. 6 ).

As shown in FIGS. 5 and 6 , the first driving part 33e and the second driving part 33f each have a rotation shaft. In addition, gears are fixed at both ends of the rotating shaft. Specifically, the first driving unit 33e includes a driving gear 33ea and a driven gear 33eb. In addition, the second drive unit 33f includes driven gears 33fa and 33fb. The drive gear 33ea of the 1st drive part 33e is arrange|positioned so that it may mesh with the gear of the humidification element 33 on the left side. Moreover, the driven gear 33fa of the 2nd drive part 33f is arrange|positioned so that it may mesh with the gear of the humidification element 33 of the right side. The driven gear 33eb of the first driving part 33e and the driven gear 33fb of the second driving part 33f are arranged to mesh with each other.

The drive gear 33ea of the 1st drive part 33e receives the rotational force from the drive motor 35, and rotates (refer FIG.7(b)). When the driving gear 33ea of the first driving part 33e rotates, the humidifying element 33 meshed with the driving gear 33ea rotates. Moreover, the driven gear 33eb of the 1st drive part 33e is also rotated by the rotation of the drive gear 33ea. Moreover, the driven gear 33fb of the 2nd drive part 33f is also rotated by the rotation of the driven gear 33eb of the 1st drive part 33e. Moreover, the driven gear 33fa of the 2nd drive part 33f is also rotated by the rotation of the driven gear 33fb of the 2nd drive part 33f. Thereby, the humidifying element 33 meshed with the driven gear 33fa of the 2nd drive part 33f rotates. That is, as one drive motor 35 rotates, the rotational force of the one drive motor 35 is sequentially transmitted to the drive gear 33ea and the driven gears 33eb, 33fb, and 33fa. As a result, both humidifying elements 33 rotate.

As shown in FIG. 2 , FIG. 4 and FIG. 6 , the humidifying element 33 includes a plurality of water-drawing parts 33c. The some water scooping part 33c is provided in the side surface of the gear of the humidification rotor 33b. That is, the water scooping part 33c is arrange|positioned at the position outside rather than the outer periphery of the humidification filter 33a. The water drawing part 33c is cup-shaped. The water drawing part 33c has the shape which can draw the water of the tray 32 (water supply part 32b) when the humidification element 33 rotates.

As shown in FIG. 3 , the humidifying element 33 is arranged such that the lower part of the humidifying filter 33 a is not immersed in the water of the tray 32 , and the tip of the gear of the humidifying rotor 33 b is near the bottom of the tray 32 at the lowest point. The water absorbing part 33c is soaked sequentially by the rotation of the humidifying element 33 to absorb the water in the tray 32 . Then, the water drawing part 33c splashes the drawn water on the humidification filter 33a in the vicinity of the highest point of the humidification element 33. Specifically, the water drawn by the water drawing part 33c flows out from the water drawing part 33c near the highest point of the humidification element 33, so that the water is splashed on the humidification filter 33a.

(3) The action of the air purifier and the flow of air.

Hereinafter, the operation of the air cleaner 10 and the flow of air accompanying the operation of the air cleaner 10 will be described using FIGS. 2 and 3 . In addition, in FIGS. 2 and 3 , symbols f1 to f5 indicate the flow of air. In addition, in FIG. 3, with regard to the flow of air flowing into the humidification chamber R3 after passing through the air purification filter 20, the solid line indicates the flow of air passing between the humidification filters 33a, and the dotted line indicates the flow of the air of the humidification filter 33a. The flow of air outside.

By turning on the power supply of the air cleaner 10, the fan motor 12b of the air blower 12 rotates the fan 12a. The rotating fan 12a blows air in a centrifugal direction, thereby reducing the pressure around the rotating shaft. Thereby, air is sucked into the fan suction port located at the center of the fan 12a. As a result, a flow of air flowing from the suction port 11a to the fan suction port is generated. In the air cleaner 10 of this embodiment, as mentioned above, the ventilation chamber R1 is provided in the lowermost part of the casing 11. As shown in FIG. Moreover, the suction port 11a is formed in the front lower part and the back lower part of the casing 11. As shown in FIG. Therefore, when the air blower 12 is driven, the air cleaner 10 sucks in air from the front lower part and the rear lower part (see symbol f1 in FIG. 3 ). That is, the air outside the housing 11 is sucked into the blower chamber R1 by the drive of the blower device 12 .

The air is blown off in the centrifugal direction from the plurality of blades 12ab by the drive of the air blower 12, and flows toward the air cleaning filter 20 (see symbol f2 in FIG. 2 and FIG. 3 ). That is, the air in air supply chamber R1 is sent to air cleaning chamber R2.

The air sent to the air cleaning room R2 first flows through the dust collection filter 21 on the upstream side. The dust collection filter 21 removes dust contained in the air. The air flowing through the dust collecting filter 21 further flows through the deodorizing filter 22 on the downstream side. Unpleasant odor components contained in the air are adsorbed to the deodorizing filter 22 by the deodorizing filter 22. In addition, static pressure acts on the entire surface of the air cleaning filter 20 due to the air squeezed from the blower chamber R1. Then, the air that has passed through the air purification filter 20 is sent to the humidification chamber R3.

The air sent to humidification chamber R3 flows upward (see symbol f3 in FIG. 2 and FIG. 3 ). In the humidification chamber R3, the flow of air along the outer surface (outer wall) of the case 31 is generated. In addition, the flow f3 of air is guided by the rectifying plate 36 to flow through the humidification filter 33a. Thus, the air flowing into the humidification chamber R3 flows in the thickness direction of the air purification filter 20 (see symbol f3 in FIG. 3 ), and then branches toward the two humidifying elements 33 (see symbol f4 in FIG. 2 ). That is, after passing through the air purification filter 20, the flow direction of the air flowing in the direction perpendicular to the thickness direction of the humidification element 33 flows along the case 31 by the air in the humidification chamber R3, thereby changing the flow direction to toward The thickness direction of the humidifying element 33 (the axial direction of the rotor rotating shaft 33d) is curved. Then, the air flows through the humidifying element 33 along the outer wall of the box 31, and is blown out from the outlet 11b (see symbol f5 in FIGS. 2 and 3 ).

In addition, when the power supply of the air cleaner 10 is set to ON, if the humidification function is set to ON, the humidifying element 33 rotates. The lower part of the humidification filter 33 a is immersed in the water of the tray 32 , and therefore, the part of the humidification filter 33 a newly immersed in water draws the water of the tray 32 by the rotation of the humidification element 33 . In addition, by the rotation of the humidifying element 33, the water drawing part 33c draws up the water of the tray 32, and sprays water toward the humidifying filter 33a in the vicinity of the highest point of the humidifying element 33. As a result, water spreads over the entire area of the humidification filter 33a. That is, in the case where the humidification function is set to ON, the air entering the humidification chamber R3 from the air purification chamber R2 promotes vaporization of the water permeated into the humidification element 33 . Thereby, the air becomes humidified air. Then, humidified air is blown out from the outlet 11b. On the other hand, when the power supply of the air cleaner 10 is set to on, if the humidification function is set to off, the humidifying element 33 does not rotate. That is, the air is blown out from the air outlet 11b without being sufficiently humidified.

(4) Assembly and disassembly of the air purification filter.

Next, the removal operation of the air cleaning filter 20 will be described with reference to FIGS. 7 and 8 . 7 and 8 each sequentially show the operation for removing the air cleaning filter 20 from the housing 11 (removal operation). Specifically, Fig. 7 (a) ~ Fig. 7 (d) use the perspective view of air purifier 10 to show the process of dismantling operation, Fig. 8 (a) ~ Fig. 8 (d) use the air purifier of Fig. 1 The schematic structural diagram of the II-II section of 10 shows the process of the dismantling operation. FIGS. 7( a ) to 7 ( d ) correspond to FIGS. 8( a ) to 8 ( d ), respectively. In addition, the attachment operation of the air purification filter 20 to the casing 11 is performed in the opposite process of the detachment operation.

Fig. 7(a) and Fig. 8(a) show the air cleaner 10 before maintenance starts. When maintenance is started, as shown in Fig. 7(b) and Fig. 8(b), first, the door 11c is opened. Specifically, the door 11c is removed from the casing 11 . As a result of the door 11c being removed, the opening 15 is opened (see FIG. 7(b)). Since the door 11c is removed, the box 31 attached to the door 11c is also removed from the casing 11 . Here, the door 11c is lifted upward, thereby detaching the case 31 from the casing 11 . In addition, the box 31 can also be detached from the casing 11 by detaching the door 11c toward the front side.

Then, as shown in FIG. 7( c ) and FIG. 8( c ), the tray 32 is removed from the casing 11 . Specifically, the tray 32 is pulled out toward the front side using the handle 32d. At this time, the humidifying element 33 is removed from the housing 11 through the opening 15 . As a result, a large space is formed above the housing 11 . In other words, by detaching the tray 32 and the humidifying element 33 from the housing 11, a space in which the air cleaning filter 20 can move can be formed in the humidifying chamber R3.

Then, as shown in FIG. 7( d ) and FIG. 8( d ), the air cleaning filter 20 is removed from the casing 11 . After moving the air cleaning filter 20 in the thickness direction of the filter and removing it from the flange part 11d, the air cleaning filter 20 is moved in the humidification chamber R3 and removed from the housing 11. In other words, the air purification filter 20 is pulled up toward the downstream side in the flow direction of air, and then removed from the casing 11 through the opening 15 .

(5) Features

(5－1)

The air cleaner 10 of the above-described embodiment includes an air cleaning filter 20 , a humidifying unit 30 , a fan (blower fan 12 a ), and a casing 11 . The air purification filter 20 removes dust contained in the air. The humidification unit 30 vaporizes the supplied water to humidify the air. The air blower 12 blows air to the air purification filter 20 and the humidification unit 30 . Specifically, the air blower 12 blows air to the air purification filter 20 and the humidification filter 33a. The casing 11 accommodates the humidifying unit 30 , the air cleaning filter 20 and the blower 12 . The casing 11 has an opening 15 for attaching and detaching the humidifying unit 30 . The humidification units 30 are arranged in a row on the downstream side of the air purification filter 20 in the detachment direction of the air purification filter 20 . The opening 15 allows the air purification filter 20 to be detached after the humidification unit 30 is detached.

Generally speaking, when the air purifier includes a humidifying unit, the air purifier is respectively provided with an opening for attaching and detaching the humidifying unit and an opening for attaching and detaching the air purifying filter. An opening for attaching and detaching the air cleaning filter is formed on a side surface of the casing so that the air cleaning filter can be inserted in a direction perpendicular to the air flow direction. The opening for attaching and detaching the humidifying unit is formed large on the side of the housing so that the box can be detached. In order to ensure the airtightness of the casing, a cover (door) is provided at the opening. Therefore, when the air cleaner includes a humidifying unit, it is necessary to provide doors for the opening for attaching and detaching the air purifying filter and the opening for attaching and detaching the humidifying unit. A certain degree of airtightness can be ensured by providing the door in the opening, but when higher airtightness is required, an increase in the number of openings is not preferable.

Therefore, in the air cleaner 10 of the above-mentioned embodiment, the opening 15 for attachment and detachment of the humidification unit 30 is also used as the opening 15 for attachment and detachment of the air purification filter 20 . Specifically, the humidifying unit 30 is arranged on the downstream side of the air cleaning filter 20 in the detachment direction of the air cleaning filter 20 . After the humidifying unit 30 is detached through the opening 15 , the air purification filter 20 can be detached from the housing 11 through the same opening 15 . That is, one opening can be used for two purposes of attaching and detaching the humidifying unit 30 and attaching and detaching the air cleaning filter 20 . As a result, the number of openings can be suppressed. Therefore, high airtightness can be obtained. In addition, since there is no need to provide a plurality of openings and doors, manufacturing man-hours can be reduced.

(5－2)

The detachment direction of the air cleaning filter 20 of the air cleaner 10 of the said embodiment is the thickness direction of the air cleaning filter 20. That is, the air cleaning filter 20 is removed in the thickness direction of the air cleaning filter 20 .

As described above, in conventional air cleaners, the air cleaning filter is inserted from the side of the housing so as to be perpendicular to the air flow direction. When an air purification filter is provided, a sealing member is generally provided in order to improve the airtightness of the air purification filter with respect to the casing. The sealing member is arranged along the outer shape of the air purification filter. Here, when the structure in which the air cleaning filter is inserted from the side of the case is adopted, when the air cleaning filter is removed, the sealing member rubs against the case or the air cleaning filter and wears out. As a result, it is difficult to ensure constant airtightness for a long time.

In the air cleaner 10 of the above-described embodiment, a sealing member is also used in order to improve the airtightness of the air cleaner filter 20 . However, in the air cleaner 10 of the above-mentioned embodiment, the air cleaner filter 20 is removed in the thickness direction of the air cleaner filter 20 . Therefore, abrasion of the air purification filter 20 during attachment and detachment of the air purification filter can be suppressed. As a result, a certain airtightness can be ensured for a long time.

In addition, in the air cleaner 10 of the above-mentioned embodiment, the air cleaning filter 20 can be detached using a large space formed after detaching the humidifying unit 30 . Thereby, the air purification filter 20 can be easily detached.

(5-3)

The air cleaner 10 of the above-mentioned embodiment further includes a sealing element (flange part 11d and sealing member 11e ) on the upstream side of the air cleaning filter 20 in the detachment direction, and the sealing element seals the gap between the air cleaning filter 20 and the casing 11. The gap between them is sealed. Specifically, as shown in FIGS. 2 and 3 , the air purification filter 20 is mounted on a flange portion 11 d and a sealing member 11 e, wherein the flange portion 11 d is formed inside the casing 11, and the sealing member 11 e It is placed on the flange portion 11d lying flat. Thereby, rattling of the air purification filter 20 with respect to the casing 11 can be suppressed.

(5-4)

In the air cleaner 10 of the above-mentioned embodiment, the humidification unit 30 has: the tank 31 which stores water; the tray 32 which receives water from the tank 31; and the humidification filter 33a which The water supplied from the tray 32 is vaporized to humidify the air. When the humidifying unit 30 is detached from the casing 11 , a large space can be formed above the air purification filter 20 in the casing 11 . Therefore, when maintaining the air cleaner 10, a sufficient space for removing the air cleaner filter 20 can be ensured. In addition, the air cleaning filter 20 can be restricted by the humidification unit 30 when the air cleaner 10 is in operation. Thereby, the stability of the air purification filter 20 can be ensured.

(6) Modification

Modifications of the above-described embodiment will be described below. In addition, in the modified example, the configuration described in the above-mentioned embodiment will be described using the same reference numerals.

(6-1) Modification 1A

In the description of the air cleaner 10 of the above embodiment, the direction in which the door 11c is provided is described as the front side (front side), but the front of the air cleaner 10 may be in any direction. For example, the direction in which the control panel 13 is provided may be defined as the front.

(6-2) Modification 1B

In the air cleaner 10 of the said embodiment, as shown in FIG. 1, the air outlet 11b is provided in the upper end part (top plate part) of the casing 11.

By providing the bypass opening 511ha in this way, the flow rate of the air flowing through the air cleaning filter 520 can be increased compared to the case where all the air is guided to the humidifying element 533 having a large pressure loss. Moreover, the ion generator 540 (refer FIG. 22) is provided in the surface of the rectifying plate 511h opposite to the humidification chamber S3. When the operation of the ion generator 540 is instructed via the control panel 513, the ion generator 540 generates plasma. The plasma is guided to the outside of the casing 511 by the air blown out of the casing 511 through the bypass opening 511ha.

(2－2) Air supply device

The air blower 512 is arrange|positioned in air blower chamber S1 (refer FIG. 22). The blower device 512 is a device that sucks the air outside the casing 511 into the blower chamber S1, and blows air toward the air cleaning chamber S2 and the humidification chamber S3. That is, the air blower 512 blows air to the air purification filter 520 and the humidification unit 530 (humidification element 533).

The air blower 512 mainly includes a fan 512a, a fan motor 512b, and a scroll case 512c (see FIG. 22 ). The fan 512a is arrange|positioned at the left side of the blower chamber S1, and the fan motor 512b is arrange|positioned at the right side of the blower chamber S1 (refer FIG. 22). The scroll casing 512c forms an air path for guiding the air blown by the fan 512a toward the first opening K1 above the fan 512a.

The fan 512a is a multi-bladed fan with a stable air volume. The fan 512a has a hub portion 512aa and a plurality of blades 512ab (see FIG. 24 ). A plurality of blades 512ab are arranged in a cylindrical shape on the periphery of the hub portion 512aa. The fan 512a is driven by a fan motor 512b, and the hub portion 512aa and the plurality of blades 512ab rotate to suck air toward the fan 512a along the rotation axis direction. At this time, air is sucked into the blower chamber S1 from the outside of the housing 511 through the suction port 511a. In the fan 512a, air is blown in the centrifugal direction from the plurality of blades 512ab. The air blown out in the centrifugal direction from the plurality of blades 512ab is guided toward the first opening K1 in the scroll housing 512c, and sent to the air cleaning chamber S2.

In addition, the air is blown out in the centrifugal direction from the plurality of blades 512ab as described above. Therefore, as shown by the dotted line arrow in FIG. Filter 521.

(2－3) Air purification filter

The air cleaning filter 520 cleans the air sucked into the air cleaner 510 . Specifically, the air cleaning filter 520 removes dust contained in the air. In addition, the air purification filter 520 removes components that cause odor.

The air cleaning filter 520 is arrange|positioned in the air cleaning room S2 (refer FIG. 22). The air purification filter 520 is arrange|positioned above the air blower 512, and is arrange|positioned below the humidification unit 530 (refer FIG. 22). Moreover, the air purification filter 520 is arrange|positioned at the downstream side of the air blower 512 in the flow direction of air, and is arrange|positioned at the upstream side of the humidification unit 530. As shown in FIG.

The air cleaning filter 520 mainly includes a dust collecting filter 521 and a deodorizing filter 522 (see FIG. 21 ). The dust collection filter 521 removes dust contained in the air. The deodorizing filter 522 removes odor-causing components contained in the air.

The deodorizing filter 522 is arranged above the dust collecting filter 521 . In other words, the deodorizing filter 522 is arranged on the downstream side in the flow direction of the air with respect to the dust collecting filter 521 .

The thickness direction of the dust collection filter 521 and the deodorization filter 522 is an up-down direction. That is, the air purification filter 520 has the vertical direction as the thickness direction. Air mainly flows through the air purification filter 520 in the thickness direction. In other words, the air cleaning filter 520 is arranged such that the air cleaning filter 520 (the dust collecting filter 521 and the deodorizing filter 522 ) expands in a direction perpendicular to the flow direction of air.

(2－3－1) Dust collection filter

The dust collection filter 521 is a filter for removing fine dust that is not removed by the pre-filter 511ac provided in the suction port 511a. The dust collection filter 521 is formed in a rectangular shape.

As the dust collection filter 521, a pleated filter in which a plurality of "pleats" are formed by turning back at a plurality of fold lines 521a is used (see FIG. 25 ). When the dust collection filter 521 is cut in a cross section perpendicular to the folding line 521, the cross section is formed in a shape having a plurality of continuous crests and troughs. By using the pleated filter, the surface area (ventilation area) of the dust collecting filter 521 can be ensured to be larger with the same installation area than when using a flat filter without "pleats".

In addition, the dust collecting filter 521 is perpendicular to the direction in which the folded line 521a of the pleated filter extends and the tongue 512ca of the scroll casing 512c of the air blower 512 extends, in other words, the direction of the rotation axis of the fan 512a of the air blower 512. It is disposed on the flange portion 511e in a manner (refer to FIG. 24 ).

As mentioned above, the dust collection filter 521 of the air purification filter 520 is arrange|positioned at the flange part 511e formed in the inside of the case 511. As shown in FIG. In other words, the dust collection filter 521 of the air cleaning filter 520 is held by the case 511 by the flange part 511e. The flange portion 511e acts as a link between the air purification filter 520 and the housing 511 by contacting (refer to FIG. 21 ) the lower surface 520ba of the peripheral portion 521b (refer to FIG. 25 ) of the dust collection filter 521 through which air does not flow. The sealing element that seals the gap between the inner walls acts. When the air is transported from the air supply chamber S1 to the air purification chamber S2, the sealing element ensures the airtightness between the air purification filter 520 and the casing 511 . The flange part 511e is arrange|positioned at the upstream side of the air purification filter 520 in the flow direction of air. In other words, the sealing element is arranged on the upstream side of the air cleaning filter 520 in the detachment direction of the air cleaning filter 520 . Attachment/detachment of the dust collection filter 521 to the case 511 will be described later.

(2－3－2) Deodorization filter

The deodorizing filter 522 is a filter for removing odor-causing components contained in the air. The deodorizing filter 522 is a filter formed in a rectangular shape.

As shown in FIGS. 26 and 27 , the deodorizing filter 522 is accommodated in a filter case 523 which will be described later. The deodorizing filter 522 is configured to be detachably attached to the filter case 523 . The attachment state of the filter housing 523 to the housing 511 and the attachment/detachment of the deodorizing filter 522 (filter housing 523 ) to the housing 511 will be described later. In addition, the filter detection sensor 525 for checking the presence or absence of the deodorizing filter 522 will also be described later.

(2－4) filter housing

The filter case 523 accommodates the air purification filter 520 . Specifically, the filter case 523 accommodates the deodorizing filter 522 (refer FIG. 26 ) which is a part of the air cleaning filter 520 .

The filter case 523 is a rectangular annular member, and houses the deodorizing filter 522 therein. The filter housing 523 has a side wall portion 523b having a substantially C-shaped cross-section, and the side wall portion 523b surrounds and holds the peripheral portion of the housed deodorizing filter 522 from above and from the side (outer peripheral side) (see FIG. 21 and FIG. 21 ). Figure 22). That is, the inner peripheral side of the side wall portion 523b is opened. The entire circumference of the deodorizing filter 522 is surrounded by the side wall part 523b. The upper and lower surfaces of the filter housing 523 have large openings, and the air flowing through the dust collection filter 521 flows through the deodorizing filter 522 housed in the filter housing 523 from below, and is blown out toward the top of the deodorizing filter 522. .

On the right surface of the side wall portion 523 b of the filter case 523 , a convex portion 523 a is provided, and the convex portion 523 a engages with a concave portion 511 g provided on the inner wall of the case 511 . The convex portion 523a is provided at two places on the right surface of the side wall portion 523b. In addition, the number of objects of the convex part 523a is an illustration, it is not limited to this, What is necessary is just to determine suitably. The number of recesses 511g provided on the inner wall of the housing 511 may also be appropriately determined in accordance with the number of protrusions 523a. Each of the protrusions 523g fits into one of the two recesses 511g (see FIG. 25 ) provided in the housing 511 .

When the filter case 523 is attached to the case 511 , the protrusion 523 a engages with the recess 511 g , and the left side of the filter case 523 is placed on a support 511 f provided inside the case 511 . In other words, in the state where the filter case 523 is attached to the housing 511, the filter case 523 is supported from below by the recessed part 511 fitted with the convex part 523a, and the support part 511f. With the filter housing 523 attached to the housing 511 , the deodorizing filter 522 is attached to the housing 511 in a horizontal state, in other words, in a state in which the thickness direction of the deodorizing filter 522 coincides with the vertical direction. Attachment/detachment of the filter case 523 to and from the housing 511 will be described later.

A notch 523ba is formed in the left central portion of the side wall 523b of the filter case 523 (see FIG. 26 ) by cutting out the wall 523b. In the notch part 523ba, the side wall part 523b is cut|disconnected so that the upper part side (upper part side of an upper surface and a side surface) remains (refer FIG. 26). In the state where the deodorizing filter 522 is accommodated in the filter case 523, the deodorizing filter 522 is exposed in the notch part 523ba.

In addition, the filter case 523 includes an airflow guide 524 disposed above the air purification filter. The airflow guide 524 is integrally formed with the filter housing 523 .

The airflow guide 524 is provided on the upper left side of the filter housing 523 (see FIG. 22 ). The airflow guide 524 is disposed above the first opening K1 formed in the casing 511 . The air flow guide 524 has: a vertical surface 524a extending upward from the left side of the front and rear side wall portions 523b; and a first guide surface 524b extending from the left side wall. The portion 523b extends obliquely upward and rightward (see FIG. 27 ). The first guide surface 524b is a curved surface for guiding the air flowing through the deodorizing filter 522 of the air cleaning filter 520 to the humidifying element 533 of the humidifying unit 530 described later. By forming the first guide surface 524b with a smooth curved surface, the air passing through the deodorizing filter 522 can be guided toward the second opening K2 and further toward the humidifying element 533 while suppressing an increase in pressure loss. The vertical surface 524a of the airflow guide 524 prevents the air flowing through the deodorizing filter 522 from flowing upward through the gap between the front and back of the first guide surface 524b of the airflow guide 524, and flows through the casing 511 and the humidification tray described later. 532 to flow out of the housing 511. The vertical surface 524 a and the first guide surface 524 b guide the air that mainly flows through the left side of the deodorizing filter 522 toward the humidifying element 533 .

A recessed portion 524d (refer to FIG. 27 ) formed to be recessed downward is provided on the upper portion of the air flow guide 524 . The recessed portion 524d is recessed not only downward but also downward of the upper surface 524c on the left side of the air flow guide 524 (see FIG. 27 ). The recessed portion 524d functions as a handle for the user to hold when attaching/detaching the filter case 523 .

In the state where the air purification filter 520 and the humidification unit 530 are attached to the casing 511, the upper surface 524c (see FIG. 26 and FIG. 27 ) of the air flow guide 524 is in contact with the lower surface 532b of the humidification tray 532 of the humidification unit 530 described later. (Refer to Figure 22). Therefore, even if air is blown from the air blower 512 to generate a force to float the air cleaning filter 520 (moving upward), the humidification tray 532 can suppress the upward movement of the air cleaning filter 520 . That is, the lower surface 532b of the humidification tray 532 functions as a movement restriction part which restricts the upward movement of the air purification filter 520.

(2-5) Filter detection sensor

Filter detection sensor 525 (see FIG. 22 ) is a sensor that detects whether or not air cleaning filter 520 is attached to housing 511 . Specifically, the filter detection sensor 525 is a sensor that detects whether or not the deodorizing filter 522 of the air cleaning filter 520 is attached to the casing 511 .

The filter detection sensor 525 mainly has the detection lever 525a and the detection switch 525b (refer FIG.28(a) and FIG.28(b)). The detection lever 525a is configured to be rotatable around a rotation shaft 525c (see FIG. 28( a ) and FIG. 28( b )). One end of the detection rod 525 a has a contact arm 525 d that extends in a direction intersecting the direction in which the detection rod 525 a extends and contacts the deodorizing filter 522 . On the other end of the detection lever 525a (the end on the side opposite to the end on which the contact arm 525d is provided via the rotation shaft 525c) is provided with a detection switch contact portion 525aa that contacts the detection switch 525b. . In addition, here, the contact arm 525d extends in an arc shape from the detection rod 525a, but is not limited to this, and the contact arm 525d may extend perpendicular to the direction in which the detection rod 525a extends.

The detection lever 525a generates a force acting in one direction around the rotation axis 525c (in such a way that the detection switch contact portion 525aa is away from the detection switch 525b) by a coil spring not shown. In the state where the contact arm 525d is not in contact with the deodorizing filter 522 (the state where the deodorizing filter 522 is not housed in the filter housing 523), as shown in FIG. 28( a), the contact arm 525d passes through the filter housing 523. The notch 523ba protrudes toward the inside of the filter housing 523 . In this state, the detection switch contact portion 525aa of the detection lever 525a is not in contact with the detection switch 525b. Therefore, in the state where the deodorizing filter 522 is not accommodated in the filter case 523, the control device (not shown) of the air cleaner 510 from the filter detection sensor 525 is not sent to the control device (not shown) of the air cleaner 510. signal of. In the above state, the control device determines that deodorizing filter 522 is not attached to air cleaner 510, and executes necessary controls such as stopping air cleaner 510 and issuing a warning that deodorizing filter 522 is not installed. In addition, although illustration and description are omitted here, when not only the deodorizing filter 522 but also the filter housing 523 is not attached to the case 511, the detection switch contact portion 525aa is also in a state of not being in contact with the detection switch 525b. , the signal sent when the deodorizing filter 522 exists is not sent to the control device.

On the other hand, when the deodorizing filter 522 is housed in the filter case 523 , the contact arm 525 d contacts the deodorizing filter 522 in the notch 523 ba of the side wall 523 b of the filter case 523 . In addition, the detection lever 525a resists the force of the coil spring not shown, and the detection switch contact part 525aa of the detection lever 525a rotates in the direction which contacts the detection switch 525b. When the detection switch contact portion 525aa contacts the detection switch 525b, the detection switch 525b is turned on, and the signal transmitted when the deodorizing filter 522 exists is sent from the filter detection sensor 525 to the control device of the air cleaner 510 . When the control device determines that the deodorizing filter 522 is attached to the air cleaner 510, the operation of the air cleaner 510 is permitted unless there are other abnormalities.

In addition, this air cleaner 510 is only provided with the filter detection sensor 525 which detects the presence or absence of the deodorizing filter 522 as a sensor for detecting the presence or absence of a filter, but it is not limited to this. For example, a sensor using the same principle as the filter detection sensor 525 or another detection principle may be provided in order to detect the presence or absence of the dust collection filter 521 . However, as will be described later, in the air cleaner 510, in the absence of the dust collection filter 521, it is difficult to install the filter housing 523 containing the deodorizing filter 522, therefore, only by detecting the deodorizing filter Whether the filter 522 is present or not, the state where the dust collection filter 521 is not installed can also be detected.

(2-6) humidification unit

Humidification unit 530 vaporizes the supplied water to humidify the air. Specifically, the humidifying element 533 of the humidifying unit 530 vaporizes the supplied water to humidify the air. Humidification unit 530 is arranged on the downstream side of air blower 512 and air purification filter 520 in the air flow direction. That is, the humidification unit 530 humidifies the air purified by the air purification filter 520 . Humidification unit 530 is a rotary humidification unit. In humidifying unit 530 , the peripheral portion of humidifying element 533 rotates to pass water stored in humidifying tray 532 described later, and the air is humidified by vaporizing water from humidifying element 533 containing water.

Humidification unit 530 is arranged in humidification chamber S3 (see FIG. 22 ) inside casing 511 . That is, the humidification unit 530 is arranged at an upper position in the casing 511 (see FIG. 22 ). A humidification box 531 , a humidification tray 532 , and a humidification element 533 , which will be described later, of the humidification unit 530 are configured to be detachable from the casing 511 . When the humidification box 531, the humidification tray 532, and the humidification element 533 are removed from the opening 515 (see FIG. 22 ) of the housing 511, a large space can be formed at an upper position in the housing 511. Specifically, when the humidification unit 530 is detached from the housing 511, a space in which the air purification filter 520 can move is formed in the humidification chamber S3. In other words, when the humidifying unit 530 is detached from the casing 511, a space is formed above the air cleaning chamber S2 as a movement path of the air cleaning filter 520 when the air cleaning filter 520 is detached. In addition, attachment/detachment of the air purification filter 520 will be described later.

As shown in FIGS. 22 and 23 , the humidification unit 530 mainly includes a humidification box 531 , a humidification tray 532 , and a humidification element 533 . Moreover, the humidification unit 530 has the humidification motor 534 (refer FIG. 22) for driving the rotation of the humidification element 533. As shown in FIG. The humidification motor 534 is provided in the casing 511 . On the other hand, humidification box 531 , humidification tray 532 , and humidification element 533 are configured to be detachable from casing 511 .

(2－6－1) humidification box

The humidification tank 531 stores water to be supplied to the humidification element 533 . The humidification box 531 is integrally formed with the first side plate 511c of the casing 511 . Therefore, the humidification unit 531 is attached and detached from the humidification unit 530 (humidification tray 532) by detaching the 1st side plate 511c from the casing 511 (refer FIG.32(b)).

The humidification box 531 is arranged on the left side of the humidification tray 532 . The humidification tray 532 is disposed on the left side of the casing 511 , and therefore, the humidification box 531 is disposed on the left side of the casing 511 .

In this air cleaner 510, the fan motor 512b of the blower 512 which is a heavy object is arranged on the right side of the housing 511 as described above (see FIG. 22 ). On the other hand, the humidification box 531 which is a heavy object is arrange|positioned at the left side of the casing 511 (refer FIG. 22). That is, the fan motor 512b is offset to one side (right side) with respect to the center of the air purification filter 520, and the humidification box 531 is offset to the opposite side (left side) from the center of the air purification filter 520. . In this way, the heavy fan motor 512b and the humidification box 531 do not deviate toward the same side when viewed from above, but are separated from each other in opposite directions. Therefore, the weight balance of the air cleaner 510 is better.

The humidification box 531 has a water injection port 531a. A water supply valve (not shown) is attached to the water injection port 531a. The water supply valve adopts a general structure that uses a spring to press the spool to the valve port, so detailed description of the water supply valve is omitted here.

The humidification box 531 is arranged in the box support part 532c mentioned later on the left side of the humidification tray 532 at the time of use. Specifically, the humidification tank 531 is attached to the tank support part 532c of the humidification tray 532 in the state which made the water injection port 531a downward. When the humidification box 531 is attached to the box support part 532c, the press-fit pin (not shown) provided in the humidification tray 532 is pressed against the water supply valve of the water inlet 531a facing downward. In addition, under the action of the weight of the humidification box 531, the water supply valve is pressed by the push-in pin to press open the valve port, so that the water injection port 531a is in an open state. As a result, water is supplied to humidification tray 532 to be described later, and the water for immersing humidification element 533 is stored up to a predetermined height of humidification tray 532 .

The humidification box 531 is formed in a substantially rectangular shape when viewed from the right side (see FIG. 21 ). In addition, the left side of the humidification box 531 is formed in a planar shape extending in a substantially vertical direction when viewed from the front side (see FIG. 22 ). In addition, the humidification box 531 is formed in a curved surface shape on the right side when viewed from the front side (see FIG. 22 ). The curved right side surface 531b (see FIG. 22 ) of the humidification box 531 functions as a guide surface that guides the air flowing through the humidification element 533 toward the outlet 511b. Specifically, the lower part of the right side surface 531b (right side lower part 531ba) is a curved surface that is depressed toward the lower left side. The right side lower part 531ba is a curved surface formed so that it becomes higher toward the left side (see FIG. 22 ). The right side lower portion 531ba is a curved surface whose slope changes so that the inclination direction becomes closer to the vertical direction as it goes to the left side (see FIG. 22 ). The upper part (right side upper part 531bb) of the right side surface 531b is a vertical surface smoothly connected to the right side lower part 531ba (see FIG. 22 ). Since the right side surface 531b is formed in the above-mentioned shape, the air flowing through the humidifying element 533 obliquely upward and leftward is guided toward the upper outlet 511b of the casing 511 without causing a large pressure loss.

(2－6－2) humidification tray

The humidification tray 532 receives the water supplied from the humidification tank 531, and temporarily stores it. Specifically, water to be supplied to a humidifying element 533 described later is stored in the humidifying tray 532 . The second side plate 511d of the casing 511 also serves as the left side wall of the humidification tray 532 .

The humidification tray 532 is arrange|positioned below the humidification element 533 (refer FIG. 22). As shown in FIG. 22 , the humidification tray 532 is formed in a substantially U-shape when viewed from the side (front in FIG. 22 ). The humidification tray 532 is arranged on the left side in the casing 511 (see FIG. 22 ). A second opening K2 is formed between the right side wall of the humidification tray 532 and the inner wall of the casing 511 (see FIG. 22 ).

The humidification tray 532 has a second guide surface 532a at the lower corner on the right side, and the second guide surface 532a guides the air passing through the air cleaning filter 520 toward the humidification element 533 (see FIG. 22 ). In other words, the humidification tray 532 has a second guide surface 532a at its lower corner adjacent to the second opening K2, and the second guide surface 532a guides the air flowing through the air purification filter 520 toward the humidification element 533 (refer to Figure 22). Specifically, the lower corner on the right side of the humidification tray 532 is curved.

The first guide surface 524 b and the second guide surface 532 a of the airflow guide 524 describe a continuous curve through a small gap G generated between the airflow guide 524 and the humidification tray 532 . Moreover, the lower surface 532b of the humidification tray 532 functions as a movement restriction part which restricts upward movement of the air purification filter 520 in the state which mounted the humidification unit 530 and the air purification filter 520 in the casing 511. In other words, the lower surface 532b of the humidification tray 532 as a movement restricting portion contacts the upper surface 524c of the airflow guide 524 to restrict the upward movement of the air purification filter 520 . Therefore, the gap generated between the air flow guide 524 and the humidification tray 532 is extremely narrow. Therefore, most of the air that flows through the deodorizing filter 522 and is guided to the first guide surface 524 b is guided to the second opening K2 and is guided toward the humidifying element 533 . In other words, almost all the air guided to the first guide surface 524b does not flow through the gap between the airflow guide 524 and the humidification tray 532, but flows out from the gap between the first side plate 511c, the second side plate 511d and the housing 511, etc. to the outside of the housing 511.

The humidification tray 532 has the tank support part 532c which receives the humidification tank 531 on the left side (refer FIG. 23). The humidification tank 531 (refer FIG. 22) in the state which the water injection port 531a faced downward is arrange|positioned in the tank support part 532c. The water supply valve of the water inlet 531a of the humidification tank 531 attached to the tank support portion 532c abuts against a press-fit pin (not shown) provided on the tank support portion 532c. In addition, the water supply valve is pushed open by the weight of the humidification box 531 by the push-in pin so that the water injection port 531 a is opened to supply water to the humidification tray 532 .

The water supplied from the humidification tank 531 is supplied to the water supply part 532d on the right side of the humidification tray 532 (refer FIG. 23). The water supply part 532d is arrange|positioned below the humidification element 533 (refer FIG. 22). The water supply part 532d is a part which supplies the water supplied from the humidification tank 531 to the humidification element 533 in the tank support part 532c.

The water supply part 532b and the tank support part 532c are partitioned by the partition wall which is not shown in figure. A notch is formed in the partition wall, and the water supplied from the humidification tank 531 to the tank support part 532c is sent to the water supply part 532d through the notch. That is, the water supplied to the tank support portion 532c arranged on the left surface side of the housing 511 is then sent to the water supply portion 532d on the right side of the housing 511 . In the water supply unit 532d, water is stored to a predetermined water level in order to immerse the humidifying element 533 . When water exists in the humidification tank 531, the water level of the water supply part 532d is automatically adjusted, and a predetermined water level is maintained.

The humidification tray 532 has a bearing part 532e (refer FIG. 29). The bearing portion 532e rotatably supports a rotor shaft 533c (see FIG. 29 ) of a humidifying element 533 described later. Moreover, the bearing part 532e is comprised so that the rotor shaft 533c can be attached and detached freely, so that the humidification element 533 can be detached at the time of maintenance etc. Specifically, the bearing portion 532e is formed in a U-shape opening upward, and the rotor shaft 533c can be attached/detached from the U-shaped opening (see FIG. 29 ).

One guide pin 532f is provided on each of the front and rear side surfaces of the water supply part 532d of the humidification tray 532 (see FIG. 29 ). When the humidification tray 532 is attached to the housing 511, the humidification tray 532 is inserted into the C-shaped guides 511i (see FIG. The tray 532 is press-fitted into the casing 511, whereby the humidification tray 532 is easily fixed at a predetermined position.

(2－6－3) humidification element

The humidifying element 533 vaporizes the supplied water to humidify the air. Specifically, the humidifying element 533 receives the supply of water stored in the humidifying tray 532, vaporizes the supplied water, and humidifies the air.

The humidifying element 533 is disposed on the right side of the humidifying tray 532 . Specifically, the humidifying element 533 is arranged above the water supply part 532d provided on the right side of the humidifying tray 532.

The humidifying element 533 is formed in a circular shape. The humidifying element 533 mainly has a humidifying filter 533a, a humidifying rotor 533b, and a rotor shaft 533c (see FIG. 29 ).

The humidification filter 533a is a vaporizer formed of nonwoven fabric. The humidification filter 533a is formed in a circular shape. The humidification filter 533a contains the water supplied from the humidification tray 532, and humidifies the air by vaporizing the water.

The humidification rotor 533b is a frame that surrounds the outer circumference of the humidification filter 533a to hold the humidification filter 533a. The humidification rotor 533b is connected to a rotor shaft 533c arranged at the center of the humidification rotor 533b.

One side (left side) of the rotor shaft 533c is rotatably supported by a bearing portion 532e provided on the humidification tray 532 . On the other side (right side), a hexagonal-shaped connection portion 533d is formed. Moreover, the front-end|tip part 533e connected to the connection part 533d is formed in the end part of the right side, and it becomes thinner toward an end part.

When the humidification tray 532 is attached to the casing 511, the rotor shaft 533c is inserted into the hole 534ba (see FIG. 29 ) of the connection receiving portion 534b of the humidification motor 534 described later from the front end portion 533e side. Further, the rotor shaft 533c is inserted into the hole 534ba until the connecting portion 533d reaches the connecting receiving portion 534b, thereby connecting the connecting portion 533d and the connecting receiving portion 534b. Specifically, the hole 534ba of the connection receiving portion 534b is a hexagonal hole having substantially the same outer shape as the connection portion 533d, and the connection portion 533d is connected to the connection by inserting the connection portion 533d into the hole 534ba formed in the connection receiving portion 534b. The receiving parts 534b are fitted and connected together. Since the connection receiving part 534b and the connection part 533d are connected together, the rotor shaft 533c and the drive shaft 534a of the humidification motor 534 mentioned later are connected together. Moreover, the motor 534 for humidification is driven, and when the drive shaft 534a rotates, the rotor shaft 533c also rotates. Here, since the connection part 533d and the hole 534ba of the connection receiver 534b are formed in a hexagonal shape, when the drive shaft 534a rotates, the connection receiver 534b rotates without idling relative to the connection part 533d.

Here, since the rotor shaft 533c has a front end portion 533e formed so as to become thinner toward the end, the front end portion 533e functions as a guide, and it is easy to insert the rotor shaft 533c into the hole 534ba of the connection receiving portion 534b.

The driving force of the rotating shaft is transmitted to the rotor rotating shaft 533c from the humidifying motor 534 described later. When the humidifying element 533 rotates, the peripheral portion of the humidifying filter 533a of the humidifying element 533 passes through the water stored in the water supply part 532d of the humidifying tray 532. When the peripheral edge part of the humidification filter 533a passes through the water accumulated in the water supply part 532d of the humidification tray 532, the humidification filter 533a receives water from the water supply part 532d. Humidification element 533 rotates to supply air blown by air blower 512 (air that has passed through air cleaning filter 520 ) toward humidification filter 533a moved above water supply part 532d. When the air flows through the humidification filter 533a, the water contained in the humidification filter 533a is vaporized, thereby humidifying the air.

(2－6－4)Motor for humidification

The humidification motor 534 is a motor for rotating the humidification element 533 .

The humidification motor 534 is provided in the casing 511 . Specifically, the humidification motor 534 is fixed to the casing 511 on the right side of the humidification unit 530 .

The humidification motor 534 transmits a driving force to a drive shaft 534a (see FIG. 22 ). When the humidification motor 534 rotates, the drive shaft 534a rotates.

The drive shaft 534a has a connection receiving portion 534b on the left side (see FIG. 22 ). A hexagonal hole 534ba is formed in the connection receiving portion 534b (see FIG. 29 ). The shape of the hole 534ba is substantially the same as the cross-sectional shape of the rotor shaft 533c. In addition, the hole 534ba is formed in a hexagonal shape slightly larger than the cross-sectional shape of the connecting portion 533d so that the connecting portion 533d of the rotor shaft 533c can be inserted. As described above, the connecting portion 533d of the rotor shaft 533c is inserted into the hole 534ba, thereby connecting the drive shaft 534a and the rotor shaft 533c together.

(3) Action of air purifier and air flow

Hereinafter, the operation of the air cleaner 510 and the flow of air accompanying the operation of the air cleaner 510 will be described using FIGS. 30 and 31 . In FIGS. 30 and 31 , the flow of air is indicated by arrows of dashed-dotted lines.

When the power supply of the air cleaner 510 is turned on, the fan motor 512b of the air blower 512 rotates the fan 512a. The rotating fan 512a blows air out in the centrifugal direction, and thus, the pressure of the rotation axis of the fan 512a is reduced, and the air is sucked into the fan suction port located at the center of the fan 512a. As a result, a flow of air flowing from the suction port 511a to the fan suction port located at the center of the fan 512a is generated. That is, the fan 512a rotates to suck air from the suction ports 511a formed in the lower left surface and the lower right surface into the blowing chamber S1. In addition, at this time, relatively large dust is removed by the pre-filter 511ac arranged at the suction port 511a.

The air blown out in the centrifugal direction from the plurality of blades 512ab (refer to FIG. 24 ) of the fan 512a of the air blower 512 is guided toward the first opening K1 by the scroll housing 512c, and is transported from the first opening K1 into the air cleaning chamber S2. (Refer to Figure 30).

First, the air sent to the air cleaning chamber S2 flows through the dust collection filter 521 arranged in the air cleaning filter 520 on the upstream side in the flow direction of the air. The dust collection filter 521 removes dust contained in the air.

The air flowing through the dust collection filter 521 further flows through the deodorizing filter 522 on the downstream side in the flow direction of the air. Components causing the odor are removed by the deodorizing filter 522 .

Then, the air passing through the air purification filter 520 is sent to the humidification chamber S3 through the second opening K2. At this time, the air flowing through the left side of the deodorizing filter 522 is smoothly guided toward the second opening K2 by the first guide surface 524b of the airflow guide 524 and the second guide surface 532a formed on the lower portion of the humidification tray 532 ( Refer to Figure 30). In addition, as described above, the upper surface 524c of the airflow guide 524 and the lower surface 532b of the humidification tray 532 are in a contact relationship, therefore, almost no gap is formed between the airflow guide 524 and the humidification tray 532, and air hardly passes through. The gap is released to the outside of the housing 511 through the opening of the housing 511 and the gaps between the first side plate 511c and the second side plate 511d. The first guide surface 524b and the second guide surface 532a draw a continuous curve with a small gap G therebetween, and the air is smoothly guided toward the second opening K2 along the curve (see FIG. 30 ).

The air sent to humidification chamber S3 flows upward and is guided toward humidification element 533 by rectifying plate 511h provided above casing 511 . In addition, since bypass openings 511ha (see FIG. 31 ) are formed at two positions of the rectifying plate 511h, part of the air (for example, 20% of the air flowing into the humidification chamber S3) flows through the bypass openings 511ha so as not to flow through the humidification chamber. The way of the element 533 is guided toward the outside of the housing 511 (refer to FIG. 31 ). The ion generator 540 is arranged on the surface of the rectifying plate 511h opposite to the humidification chamber S3, and the plasma generated by the ion generator 540 is sent out of the casing 511 together with the air flowing through the bypass opening 511ha.

When the humidification function of the air cleaner 510 is activated, the humidification element 533 is rotated by the humidification motor 534 . Since the humidifying element 533 is placed on the water supply part 532d of the humidifying tray 532 with its lower part immersed in water, the newly immersed part of the humidifying filter 533a absorbs water from the humidifying tray 532 when the humidifying element 533 rotates. The air flowing through the humidifying element 533 promotes vaporization of the water permeated into the humidifying filter 533a. Thereby, the air becomes humidified air.

The right side 531b of the humidifying box 531 acts as a guide surface for the humidified air that flows through the humidifying element 533, so the air flow in the upper left direction obliquely becomes the air flow vertically upward, and is blown out from the outlet 511b ( Refer to Figure 30).

In addition, the case where the humidification function is set to ON has been described above, but when the humidification function is set to OFF, the humidifying element 533 does not rotate, and the air flowing through the humidifying element 533 is hardly humidified. is blown out from the outlet 511b.

(4) Removal of the humidification unit and air purification filter

Next, detaching of the humidifying unit 530 and the air cleaning filter 520 will be described mainly with reference to FIGS. 32 and 33 . FIG. 32 shows detachment of the humidification unit 530 and the air purification filter 520 from the housing 511 . In FIG. 32 , detachment work of the humidification unit 530 and the air purification filter 520 is drawn using a cross-sectional view of the inside of the housing 511 viewed from the front. Fig. 33 detaches humidification unit 530 from housing 511 and depicts the detachment operation. In FIG. 33 , detachment work of the humidification unit 530 is drawn using a perspective view of the housing 511 viewed from the left front.

32( a ) and FIG. 33( a ) show the air cleaner 510 before the detachment work of the humidification unit 530 and the air cleaning filter 520 is started.

When detaching the humidifying unit 530 and the air purification filter 520, first, the user holds the handle 511ca of the first side plate 511c, as shown in Figure 32 (b) and Figure 33 (b), and the first side plate 511c is connected to the second The upper part of the one side plate 511c is opened so as to incline to the left side. Then, the humidification box 531 is removed from the casing 511 by pulling the humidification box 531 formed integrally with the first side plate 511c obliquely upward and leftward (see FIG. 32( b ) and FIG. 33( c )).

Next, as shown in FIGS. 32( c ) and 33 ( d ), the humidification tray 532 is removed from the housing 511 . Specifically, the user holds the handle 511da provided on the second side plate 511d constituting a part of the humidification tray 532, and draws the humidification tray 532 toward the front side (left side). At this time, the connecting portion 533d of the rotor shaft 533c of the humidifying element 533 is detached from the connecting receiving portion 534b provided on the driving shaft 534a connected to the humidifying motor 534 . Here, the connection part 533d is only inserted into the hole 534ba of the connection receiving part 534b, and is not particularly fixed by a fixing member (such as a screw, etc.). Therefore, the connection part 533d can be easily extracted from the hole 534ba (see FIG. 29 ). Here, since the guide pin 532f provided on the side surface of the humidification tray 532 moves along the guide 511i formed on the inner surface of the housing 511, the user can smoothly draw the humidification tray 532 to the left in the horizontal direction ( Refer to Figure 29).

By detaching the humidifying tray 532 in which the humidifying element 533 is mounted on the bearing portion 532e in this way from the housing 511, the opening 515 on the left side of the housing 511 is opened in a large area (see FIG. 32( d) and FIG. 33 ( d)). In addition, a large space is formed in the upper part of the casing 511 after the humidification tray 532 is removed. In other words, by detaching the humidification tray 532 and the humidification element 533 from the casing 511, a space in which the air purification filter 520 can move can be formed in the humidification chamber S3.

Then, as shown in FIG. 32( d ), first, the deodorizing filter 522 of the air cleaning filter 520 is removed from the casing 511 . Specifically, the user holds the concave portion 524d on the upper surface of the airflow guide 524 integrally formed with the filter case 523, lifts the filter case 523 upward from the support portion 511f of the housing 511, and lifts the The protrusion 523 a on the right surface of the housing 523 is pulled out from the recess 511 g of the housing 511 . Next, the user holds the recessed portion 524d, moves the filter case 523 in the thickness direction (upward direction) of the deodorizing filter 522, and then moves in the humidification chamber S3 to remove it from the inside of the housing 511. In other words, the deodorizing filter 522 is pulled up toward the downstream side in the flow direction of the air, and then removed toward the outside of the housing 511 through the opening 515 .

Finally, as shown in FIG. 32( e ), the dust collecting filter 521 of the air cleaning filter 520 is removed from the casing 511 . Specifically, the user lifts the dust collecting filter 521 from the flange portion 511e of the casing 511, moves the dust collecting filter 521 along the thickness direction (upward direction) of the dust collecting filter 521, and then humidifies The chamber S3 is moved and removed from the inside of the housing 511 . In other words, the dust collection filter 521 is pulled up toward the downstream side in the flow direction of the air, and then removed from the casing 511 through the opening 515 .

(5) Installation of humidification unit and air purification filter

Next, attachment of humidification unit 530 and air purification filter 520 will be described. In addition, if the diagrams in Fig. 32 and Fig. 33 are viewed in reverse order, it is equivalent to depicting the installation operation of the humidifying unit 530 and the air purifying filter 520, so here, the depicting of the humidifying unit 530 and the air purifying filter 520 is omitted. A drawing showing the status of the installation work of the device 520.

The installation of the humidifying unit 530 and the air purifying filter 520 will be described based on the state where the air purifying filter 520 and the humidifying unit 530 are all removed.

First, first, the dust collection filter 521 of the air cleaning filter 520 is installed in the casing 511 . Specifically, after the user inserts the dust collection filter 521 into the humidification chamber S3 through the opening 515, the user moves the dust collection filter 521 downward and places it on the flange portion 511e of the casing 511 (see FIG. ), Figure 32(e)).

Next, the user attaches the deodorizing filter 522 housed in the filter case 523 to the casing 511 above the dust collecting filter 521 .

Specifically, the user holds the recess 524d of the air flow guide 524 formed integrally with the filter case 523, and inserts the filter case 523 into the humidification chamber S3 through the opening 515 while lowering the right side. Then, the user slides the right side of the lower surface of the filter housing 523 on the upper surface 521bb (refer to FIG. 32( d)) of the peripheral edge portion 521b (refer to FIG. 25 ) of the dust collection filter 521, and the filter housing 523 moves from left to right. In addition, at this time, the user moves the filter housing 523 from the left side to the right side while gradually lowering the left side of the filter housing 523 downward. The filter case 523 moves to the right side on the dust collection filter 521 until the convex part 523a formed in the filter case 523 and the recessed part 511g provided in the case 511 fit. In the state where the convex part 523a fits in the recessed part 511g, the left side of the filter case 523 can be lowered and can be mounted on the support part 511f. On the other hand, when the protrusion 523a is not fitted into the recess 511g, the left side of the filter case 523 interferes with the inner surface of the case 511, and the filter case 523 cannot be accommodated in the case 511.

In addition, assuming that the filter housing 523 is to be installed in a state where the dust collection filter 521 is not installed, there is no structure supporting the filter housing 523 on the lower side, and there is no mechanism for guiding the convex portion 523a of the filter housing 523 toward the concave portion 511g. structure. Therefore, when the filter case 523 is to be attached without the dust collection filter 521 attached, the right side of the filter case 523 tends to fall downward as shown in FIG.

In the state where the deodorizing filter 522 housed in the filter case 523 is attached to the case 511, that is, the convex portion 523a of the filter case 523 is fitted into the concave portion 511g of the case 511, and the left side of the filter case 523 is supported. In the state of the support part 511f, the filter case 523 is in the state which contacted the upper surface 521bb (refer FIG. 21) of the peripheral edge part 521b (refer FIG. 25) of the dust collection filter 521. In addition, as described later, when the humidification tray 532 and the humidification box 531 are attached to the casing 511, the lower surface 532b of the humidification tray 532 is in contact with the upper surface 524c of the air flow guide 524 integrally formed with the filter case 523. status. The upward movement of the filter case 523 is restricted by the humidification tray 532 and the humidification box 531. In addition, the upper surface 521bb of the peripheral portion 521b of the filter case 523 and the dust collection filter 521 is in a contact state, even if the air flow The upward movement of the dust filter 521 can also be prevented by acting on the dust collecting filter 521 with a force of floating up.

When attachment of the air purification filter 520 is completed, the humidification tray 532 is attached to the casing 511 (refer FIG.32(c), FIG.33(d)). Specifically, the user grips the handle 511da provided on the second side plate 511d constituting a part of the humidification tray 532, and moves the humidification tray 532 to the right side in the horizontal direction so that the guide pin 532f provided on the humidification tray 532 fits into it. The guide 511i provided on the front and rear inner walls of the casing 511 and the front end 533e of the rotor shaft 533c of the humidifying element 523 are inserted into the hole 534ba of the connecting receiving portion 534b of the driving shaft 534a connected to the humidifying motor 534 (see FIG. 29 ). Here, the guide 511i and the connection receiving part 534b function as a guide, and it is easy to move the humidification tray 532 in the horizontal direction. In addition, when the connecting portion 533d is inserted into the hole 534ba, if the orientation of the hexagonal shape of the connecting portion 533d does not coincide with the orientation of the hexagonal hole 534ba, the humidifying element 533 is formed in the hexagonal shape of the connecting portion 533d. The connection part 533d and the connection receiving part 534b are connected together by rotating so that the orientation of a shape may match the orientation of the hexagonal hole 534ba.

When the humidification tray 532 is attached to the casing 511 , the lower surface 532 b of the humidification tray 532 is in contact with the upper surface 524 c of the air flow guide 524 integrally formed with the filter case 523 . Humidification tray 532 is in contact with upper surface 524c of airflow guide 524, and air purification filter 520 is prevented from moving upward even if a force of lifting air purification filter 520 is applied due to the flow of air. That is, here, the lower surface 532b of the humidification tray 532 functions as a movement restricting part which restricts upward movement of the air purification filter 520. As shown in FIG.

Finally, the user holds the handle 511ca of the first side plate 511c, and the lower side of the first side plate 511c formed integrally with the humidification box 531 is tilted to the left with the upper part of the first side plate 511c and the second side plate 511d. The upper side of the upper part is engaged (refer to Fig. 32(b), Fig. 33(b)). Next, the opening 515 of the casing 511 is closed by erecting the first side plate 511c along the vertical direction (see FIG. 32( a ) and FIG. 33( a )).

(6) Features

(6－1)

The air purifier 510 in the above embodiment includes an air purifying filter 520 , a humidifying unit 530 , a fan 512 a and a casing 511 . The air purification filter 520 removes dust contained in the air. Humidification unit 530 vaporizes the supplied water to humidify the air. The air blower 512 blows air toward the air purification filter 520 and the humidification unit 530 . Specifically, the air blower 512 blows air to the air purification filter 520 and the humidification filter 533a. The casing 511 accommodates the humidifying unit 530, the air purification filter 520, and the fan 512a. The casing 511 has an opening 515 for attaching and detaching the humidifying unit 530 . Humidification unit 530 is arranged in a row on the downstream side of air purification filter 520 in the detachment direction of air purification filter 520 . The opening 515 allows the air purification filter 520 to be detached after the humidification unit 530 is detached.

In the air cleaner 510 of the above-mentioned embodiment, the opening 515 for attachment and detachment of the humidification unit 530 is also used as the opening 515 for attachment and detachment of the air purification filter 520 . Specifically, humidification unit 530 is arranged on the downstream side of air purification filter 520 in the detachment direction of air purification filter 520 . After the humidifying unit 530 is detached through the opening 515 , the air purification filter 520 can be detached from the housing 511 through the same opening 515 . That is, one opening 515 can be used for two purposes of attaching and detaching the humidifying unit 530 and attaching and detaching the air purification filter 520 . As a result, the number of openings can be suppressed, and high airtightness of the casing 511 can be obtained. In addition, since there is no need to provide a plurality of openings and doors, manufacturing man-hours can be reduced.

(6－2)

The detachment direction of the air cleaning filter 520 of the air cleaner 510 of the said embodiment is the thickness direction of the air cleaning filter 520. That is, here, the detachment direction of the air purification filter 520 is an up-down direction.

In the air cleaner 510 of the above-mentioned embodiment, the air cleaner filter 520 is removed in the thickness direction of the air cleaner filter 520 . Therefore, compared with the case where the air purification filter 520 is drawn out from the housing 511 in the horizontal direction, abrasion of the air purification filter 520 and the housing 511 (clamping between the air purification filter 520 and the housing 511) is less likely to occur. It is not easy to cause the wear of the seal when the seal is held). As a result, a certain airtightness can be ensured for a long time.

In addition, in the air cleaner 510 of the above-mentioned embodiment, the air cleaning filter 520 can be detached using a large space formed after detaching the humidifying unit 530 . Thereby, the air cleaning filter 520 can be easily detached.

(6-3)

The air cleaner 510 of the above embodiment further includes a flange portion 511e on the upstream side of the air purification filter 520 in the detachment direction, and the flange portion 511e serves as a seal for the gap between the air purification filter 520 and the housing 11. sealing elements.

Specifically, the air purification filter 520 is mounted on a flange portion 511 e formed inside the casing 511 . Thereby, rattling of the air purification filter 520 with respect to the casing 511 can be suppressed. In addition, a seal may be further disposed between the air purification filter 520 and the housing 511 .

(6-4)

In the air cleaner 510 of the above embodiment, the humidification unit 530 has: a humidification box 531 that stores water; a tray 532 that receives water from the humidification box 531; and a humidification filter 533a that The filter 533a contains water supplied from the humidification tray 532, and humidifies the air by vaporizing the water.

When the humidifying box 531 , the humidifying tray 532 and the humidifying element 533 of the humidifying unit 530 are removed from the housing 511 , a larger space is formed above the air purification filter 520 in the housing 511 . Therefore, when the air cleaner 510 is maintained, a sufficient space for removing the air cleaner filter 520 can be ensured. In addition, when the air cleaner 510 is operating, the air cleaner filter 520 can be limited by the humidification unit 530 . Thereby, the stability of the air purification filter 520 can be ensured.

(6-5)

In the air cleaner 510 of the above embodiment, the humidification unit 530 is arranged above the air cleaner filter 520 in the housing 511 . The humidification unit 530 has the lower surface 532b of the humidification tray 532 as a movement restricting part. The lower surface 532b of the humidification tray 532 restricts the upward movement of the air purification filter 520 in the state where the humidification unit 530 and the air purification filter 520 are mounted in the casing 511 .
