The flange portion 11 f is also provided at a predetermined height position along the inner periphery of the casing 11. A tray 32 of a humidifying unit 30 to be described later is placed on the flange portion 11f. That is, the flange portion 11 f is disposed on the upstream side in the air flow direction with respect to the humidifying unit 30.

As shown in FIG. 1, a control panel 13 is provided above the side surface of the casing 11. The control panel 13 is provided with various switches (for example, a power switch and a function selection switch) for operating the air cleaner 10. The control panel 13 is connected to a control device (not shown) built in the casing 11. The signal received by the control panel 13 is transmitted to the control device.

(2-2) Blower Device The blower device 12 takes air outside the casing 11 into the blower chamber R1. Moreover, the air blower 12 blows the air taken into the air blowing chamber R1 toward the air cleaning chamber R2 and the humidifying chamber R3. That is, the air blower 12 blows air toward the air purification filter 20 and the humidification unit 30 (humidification element 33).

The air blower 12 includes a fan (blower fan) 12a and a fan motor 12b as shown in FIG. The fan 12a is a sirocco fan. The fan 12a includes a hub portion 12aa and a plurality of blades 12ab. The plurality of blades 12ab are arranged in a cylindrical shape on the periphery of the hub portion 12aa. As the hub portion 12aa and the plurality of blades 12ab rotate, air is sucked in along the rotation axis direction and further blown out from the plurality of blades 12ab in the centrifugal direction. That is, by the rotation of the hub portion 12aa and the plurality of blades 12ab, air is sucked into the blower chamber R1 from the outside of the casing 11 through the suction port 11a. The air blown in the centrifugal direction from the plurality of blades 12ab is then sent to the air cleaning chamber R2.

In addition, the air blower 12 is arrange | positioned in the plane center in ventilation chamber R1. Specifically, the air blower 12 is arrange | positioned in the center position in the depth direction and the width direction of the air cleaner 10 (refer FIG. 3). That is, the air sucked into the blower chamber R1 by the blower 12 is sent from the center of the blower chamber R1 toward the center of the air cleaning chamber R2.

(2-3) Air Purifying Filter The air purifying filter 20 purifies the air sucked into the air purifier 10. Specifically, the air purification filter 20 removes dust contained in the air. The air purification filter 20 is arrange | positioned in the downstream of the air blower 12 in the flow direction of air. Moreover, the air purifying filter 20 is arrange | positioned in the upstream of the humidification unit 30 in the air flow direction.

2 and 3, the air purification filter 20 includes a dust collection filter 21 and a deodorization filter 22. The dust collection filter 21 is a thin and soft resin net. 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 collection filter 21 and the deodorizing filter 22 are sequentially arranged from the upstream side in the air flow direction in the air cleaning chamber R2. Specifically, the dust collection filter 21 and the deodorizing filter 22 are arranged along the respective thickness directions. The thickness direction of the dust collection filter 21 and the deodorizing filter 22 coincides with the flow direction f2 of air passing through the air cleaning chamber R2. In other words, the air purification filter 20 is arranged in a direction orthogonal to the air flow direction f2.

The air purifying filter 20 is placed on the flange portion 11d formed inside the casing 11 as described above. In other words, the air purification filter 20 is held by the flange portion 11d. A seal member 11e is provided between the air cleaning filter 20 and the flange portion 11d. The seal member 11e is disposed in a plane on the flange portion 11d. Specifically, the seal member 11e is disposed along the surface of the flange portion 11d. As described above, the flange portion 11d and the seal member 11e function as a sealing unit that seals the gap between the air purification filter 20 and the inner wall of the casing 11. The flange portion 11d and the seal member 11e are disposed on the upstream side of the air purification filter 20 in the air flow direction. In other words, the sealing means is arranged on the upstream side of the air purification filter 20 in the removal direction of the air purification filter 20. The sealing means ensures the sealing performance between the air cleaning filter 20 and the casing 11 when air is sent from the blower chamber R1 to the air cleaning chamber R2.

During maintenance, the air purification filter 20 is attached and detached through the opening 15 (see FIG. 7). Specifically, the air purifying filter 20 moves using a space formed in the casing 11 (that is, the humidifying chamber R3) after the humidifying unit 30 described later is removed through the opening 15, and thereafter, It is attached / detached through the opening 15. Specifically, the air purification filter 20 is moved in the thickness direction of the air purification filter 20 and removed from the casing 11. That is, the thickness direction of the air purification filter 20 matches the removal direction (removal direction) of the air purification filter 20. Moreover, the removal direction of the air purifying filter 20 and the air flow direction in the air purifying chamber R2 coincide. In other words, the dust collection filter 21 and the deodorizing filter 22 are moved away from the flange portion 11d and removed from the casing 11 by moving along the air flow direction in the air cleaning chamber R2.

(2-4) Humidification unit The humidification unit 30 vaporizes the supplied water to humidify the air. The humidification unit 30 is arrange | positioned in the downstream of the air blower 12 and the air purifying filter 20 in the air flow direction. That is, the humidification unit 30 humidifies the air cleaned by the air cleaning filter 20.

FIG. 5 and FIG. 6 show a schematic configuration of the humidifying unit 30. FIG. 5 shows the humidification unit 30 attached to the casing 11. FIG. 6 shows the humidification unit 30 in a separated state when being removed from the casing 11.

The humidification unit 30 is arrange | positioned in the humidification chamber R3 within the casing 11, as mentioned above. That is, the humidification unit 30 is disposed at an upper position in the casing 11. When the humidification unit 30 is removed from the casing 11, a large space is formed at an upper position in the casing 11. Specifically, when the humidifying unit 30 is removed from the casing 11, a space in which the air purifying filter 20 can move is formed in the humidifying chamber R3. In other words, when the humidification unit 30 is removed from the casing 11, a space serving as a movement path when the air purification filter 20 is removed is formed above the air purification chamber R2. The air purification filter 20 is moved in the thickness direction of the air purification filter 20 (a direction orthogonal to the air purification filter 20) and removed from the flange portion 11d.

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

(2-4-1) Tank The tank 31 stores water to be supplied to the plurality of humidifying elements 33. The tank 31 has a water inlet 31a. A water supply valve (not shown) is attached to the water injection port 31a. The water supply valve has a general structure in which a valve body is pressed against a valve opening by a spring. Therefore, detailed description of the water supply valve is omitted here.

The tank 31 is placed on a tank receiving portion 32a of a tray 32, which will be described later, during use (see FIGS. 4 and 6). Specifically, the tank 31 is mounted on the tray 32 with the water supply valve facing downward. The tank 31 is pressed against the pressing pin of the tray 32 with the water supply valve directed vertically downward. Thereby, the pushing pin opens the water supply valve by the weight of the tank 31 itself.

2 and 3, the tank 31 is disposed in the vicinity of the air outlet 11 b inside the casing 11. Further, as shown in FIG. 4, the tank 31 is disposed at the center in the left-right direction in the casing 11. Moreover, the side surface of the front side of the tank 31 is attached to the door 11c as described above.

As shown in FIG. 5, a plurality of humidifying elements 33 to be described later are disposed on both sides of the tank 31 in the width direction. In other words, the tank 31 is disposed adjacent to the plurality of humidifying elements 33. In detail, the tank 31 is arrange | positioned in the aspect which obstruct | occludes partially the space between a pair of humidification elements 33 arrange | positioned facing. In other words, the tank 31 is partially inserted into the space sandwiched between the pair of humidifying elements 33.

The tank 31 has a plurality of outer surfaces as shown in FIG. The plurality of outer surfaces include a back side vertical surface F1, a side vertical surface F2, a curved surface F3, and a side inclined surface F4.

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

The side vertical surface F2 is a surface extending from the left and right sides of the back side vertical surface F1 toward the front side. The side vertical surface F2 is a surface orthogonal 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. Although FIG. 6 shows only the side vertical surface F2 located on the right side of the tank 31, the tank 31 also has a side vertical surface F2 on the left side. The side vertical plane F2 has a 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 forward. Specifically, the upper end of the curved surface F3 is at the same planar position as the back side vertical surface F1, and the lower end of the curved surface is at a planar position on the front side of the back side vertical surface F1. That is, the lower end of the curved surface F3 is located on the front side of the plane position of the back side vertical surface F1.

The side inclined surface F4 is a wall surface that connects 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 tank 31 also has the side inclined surface F4 on the left side. The side inclined surface F4 has a symmetrical shape. The side inclined surface F4 has an inclination with respect to the flow direction of the air that has passed through the air cleaning filter 20. The flow direction of the air that has passed through the air cleaning filter 20 is a direction orthogonal to the thickness direction of the humidifying element 33 (see reference numeral f3 in FIG. 2). Specifically, the side inclined surface F4 is inclined toward the center in the width direction of the air cleaner 10 from the front side to the back side. In other words, the side inclined surface F4 extends inward from the outer side in the width direction of the air cleaner 10 from the front side to the back side of the air cleaner 10. The inclination angle of the side inclined surface F4 with respect to the side vertical surface F2 can be appropriately determined depending on the distance from the adjacent humidifying element 33, the size of the space in the humidifying chamber R3, and the like. Specifically, the inclination angle is such that the air sent into the humidification chamber R3 flows along the side inclined surface F4 so that it is suitably guided in the thickness direction of the humidification element 33. Designed.

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

More specifically, the side inclined surface F4 allows the air flowing along the tank 31 to flow toward the humidifying elements 33 arranged adjacent to both sides of the tank 31. Thereby, the flow of the air which goes to the humidification element 33 is formed in humidification chamber R3. That is, the side inclined surface F4 changes the air flow that has passed through the air cleaning filter 20 so as to guide the humidifying element 33 (see FIG. 2). In other words, since the side inclined surface F4 is inclined with respect to the flow direction (substantially vertical direction) of the air that has passed through the air purification filter 20, the substantially vertical air flow is changed in the thickness direction of the humidifying element 33. (See symbols f3 and f4 in FIGS. 2 and 3). Thereafter, air that flows in the thickness direction of the humidifying element 33 (air that has passed through the humidifying element 33) is guided to the side vertical surface F2 and blown out from the air outlet 11b.

Thus, the air flowing in the direction orthogonal to the thickness direction of the humidifying element 33 changes the flow direction, passes through the humidifying element 33, and further flows along the outer surface of the tank 31 so as to be blown out from the outlet 11b. In addition, the tank 31 is disposed adjacent to the plurality of humidifying elements 33. That is, by arranging the tank 31 adjacent to the plurality of humidifying elements 33, the flow direction of the air flowing in the vicinity of the plurality of humidifying elements 33 changes. As a result, the flow direction of the air that has passed through the air cleaning filter 20 is changed so as to pass through the humidifying element 33, and further, after passing through the humidifying element 33, the flow direction is changed so as to be blown out from the outlet 11b. Is done.

(2-4-2) Tray The tray 32 receives the water supplied from the tank 31 and temporarily stores it. Further, the tray 32 supplies water to a plurality of humidifying elements 33 described later. As shown in FIG. 4, the tray 32 has a shape similar to a U shape in plan view. Specifically, the tray 32 is configured by a portion corresponding to the bottom of the U shape (a portion corresponding to the bottom) and a portion extending from both sides of the bottom corresponding portion (extension portion) in plan view. The bottom corresponding portion extends in the width direction (left-right direction) of the air cleaner 10. The extended portion extends in the depth direction (front-rear direction) on each of the left and right sides of the air cleaner 10. The tray 32 is disposed immediately above the air purification filter 20 described above. Specifically, the tray 32 is placed on the flange portion 11f as described above.

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

(A) Tank receiving portion The tank receiving portion 32a receives the tank 31 described above. The tank receiving part 32a is located in the above-mentioned bottom corresponding part. The tank receiving portion 32a is provided with a support portion and a push pin (not shown). The support portion supports a predetermined portion of the tank 31 (a corner of the tank 31). The pushing pin hits the water supply valve when the tank 31 is lowered by its own weight and pushes the water supply valve open. As a result, the water in the tank 31 is supplied to the tank receiver 32a.

A handle 32d is provided on the outer wall of the tank receiving portion 32a (see FIG. 1). The user puts a finger into the handle 32d and pulls the tank receiving portion 32a forward (front side), whereby the tray 32 is pulled out from the casing 11.

(B) Water Supply Unit The water supply unit 32 b is a part that supplies the water supplied from the tank 31 to the humidifying element 33. Specifically, the water supply part 32 b receives the water supplied to the tank receiving part 32 a and then supplies it to the humidifying element 33. The water supply part 32b is located in the above-mentioned extension part.

The water supply part 32b and the tank receiving part 32a described above are partitioned by a partition wall (not shown). A hole is formed in the partition wall. The water supplied from the tank 31 to the tank receiving part 32a is sent to the water supply part 32b through the hole. That is, the water received by the tank receiving portion 32 a disposed on the front side of the casing 11 is then sent in the depth direction on both the left and right sides of the casing 11. The water supply unit 32b is filled with water up to a predetermined water level. That is, in the water supply part 32b, in order to immerse the humidifying element 33, water is stored up to a predetermined water level. As long as there is water in the tank 31, the water stored in the water supply unit 32b is automatically adjusted so as to be maintained at a predetermined water level. In this way, water received from one tank 31 by one tray 32 is supplied to the plurality of humidifying elements 33.

(C) Bearing part The bearing part 32c is a part which receives the rotating shaft (rotor rotating shaft) 33d of the humidification element 33 mentioned later. The bearing part 32c is located in the above-mentioned 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 the present embodiment, the water supply parts 32b extend on both sides of the air cleaner 10 in the width direction. Therefore, the bearing part 32c is provided with respect to each of the water supply part 32b located in the width direction both sides. In addition, the bearing part 32c provided in each water supply part 32b is arrange | positioned in the same plane position in the depth direction. That is, each of the bearing portions 32c provided in the plurality of water supply portions 32b is disposed at a position facing each other.

A U-shaped recess is formed at the upper end of the bearing portion 32c to support the rotor rotation shaft 33d in a rotatable manner.

(2-4-3) Humidification element The humidification element 33 vaporizes the supplied water to humidify the air. Specifically, the humidifying element 33 vaporizes the water stored in the tray 32 and humidifies the air. More specifically, the humidifying element 33 vaporizes the water stored in the water supply part 32b and humidifies the air.

In the present embodiment, a plurality of humidifying elements 33 are used. Specifically, two humidifying elements 33 are used. The two humidifying elements 33 are arranged in parallel. 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. The two humidifying elements 33 are arranged close to both sides of the tank 31 as shown in FIGS. Moreover, the two humidification elements 33 are arrange | positioned in the position which opposes.

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

Each of the two humidifying elements 33 is a rotary type. Specifically, the humidifying element 33 mainly includes a humidifying filter 33a and a humidifying rotor 33b. The humidification filter 33a is a vaporizing material formed in a disk shape from a non-woven fabric. The humidification filter 33a has a filter surface. The two humidifying elements 33 are arranged so that the filter surfaces face each other. The humidification rotor 33b is a frame that surrounds the outer circumference of the humidification filter 33a and holds the humidification filter 33a. The humidification rotor 33b has a rotor rotation shaft 33d at the center and a gear (not shown) on the outer periphery. The gear is configured such that the first drive unit 33e and the second drive unit 33f are engaged with each other (see FIGS. 5 and 6).

As shown in FIGS. 5 and 6, the first drive unit 33e and the second drive unit 33f each have a rotation axis. Further, gears are fixed to both ends of the rotating shaft. Specifically, the first drive unit 33e includes a drive gear 33ea and a driven gear 33eb. The second drive unit 33f includes driven gears 33fa and 33fb. The drive gear 33ea of the first drive unit 33e is disposed so as to mesh with the gear of the left humidifying element 33. Further, the driven gear 33fa of the second drive unit 33f is disposed so as to mesh with the gear of the right humidifying element 33. The driven gear 33eb of the first driving unit 33e and the driven gear 33fb of the second driving unit 33f are arranged to mesh with each other.

The drive gear 33ea of the first drive unit 33e is rotated by the rotational force transmitted from the drive motor 35 (see FIG. 7B). As the drive gear 33ea of the first drive unit 33e rotates, the humidifying element 33 that meshes with the drive gear 33ea rotates. Further, the driven gear 33eb of the first driving unit 33e also rotates due to the rotation of the driving gear 33ea. Furthermore, the driven gear 33fb of the second drive unit 33f also rotates by the rotation of the driven gear 33eb of the first drive unit 33e. Further, the driven gear 33fa of the second drive unit 33f also rotates due to the rotation of the driven gear 33fb of the second drive unit 33f. As a result, the humidifying element 33 that meshes with the driven gear 33fa of the second drive unit 33f rotates. That is, when 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, 33fa. As a result, both the two humidifying elements 33 rotate.

The humidifying element 33 includes a plurality of water pumping portions 33c as shown in FIGS. The plurality of water drawing portions 33c are provided on the side surface of the gear of the humidification rotor 33b. That is, the water drawing part 33c is arrange | positioned outside the outer periphery of the humidification filter 33a. The water drawing part 33c is cup-shaped. The water pumping part 33c has a shape that can pump up the water of the tray 32 (water supply part 32b) when the humidifying element 33 rotates.

As shown in FIG. 3, the humidifying element 33 does not have the lower part of the humidifying filter 33 a immersed in the water of the tray 32, and the gear tooth of the humidifying rotor 33 b is close to the bottom surface of the tray 32 at the lowest point. Are arranged to be. As the humidifying element 33 rotates, the water pumping part 33c is sequentially immersed to pump up the water in the tray 32. Thereafter, the water-pumping part 33 c drips the pumped water onto the humidifying filter 33 a in the vicinity of the uppermost point of the humidifying element 33. Specifically, the water pumped up by the water pumping part 33 c flows out of the water pumping part 33 c in the vicinity of the uppermost point of the humidifying element 33 and bathes the humidifying filter 33 a.

(3) Operation of Air Cleaner and Air Flow Hereinafter, the operation of the air cleaner 10 and the air flow accompanying the operation of the air cleaner 10 will be described with reference to FIGS. 2 and 3. 2 and 3, reference numerals f1 to f5 indicate air flows. Moreover, in FIG. 3, as for the flow of air that has flowed into the humidification chamber R3 after passing through the air purification filter 20, the solid line indicates the flow of air that passes between the humidification filters 33a, and the broken line indicates the humidity filter 33a. The outside air flow is shown.

When the power of the air cleaner 10 is turned on, the fan motor 12b of the blower 12 rotates the fan 12a. Since the rotating fan 12a blows out air in the centrifugal direction, the pressure around the rotation axis decreases. Thereby, air is sucked into the fan suction port located at the center of the fan 12a. As a result, an air flow from the suction port 11a toward the fan suction port is generated. As described above, in the air cleaner 10 according to the present embodiment, the air blowing chamber R 1 is provided at the lowermost portion of the casing 11. Further, the suction port 11 a is formed in the lower front portion and the lower rear portion of the casing 11. Therefore, when the air blower 12 is driven, the air purifier 10 sucks air from the lower front portion and the lower rear portion (see reference numeral f1 in FIG. 3). That is, the air outside the casing 11 is sucked into the blower chamber R1 by driving the blower 12.

By driving the blower 12, air is blown out in the centrifugal direction from the plurality of blades 12ab and flows toward the air cleaning filter 20 (see reference numeral f2 in FIGS. 2 and 3). That is, the air in the blower chamber R1 is sent to the air cleaning chamber R2.

The air sent to the air cleaning chamber R2 first passes through the upstream dust collecting filter 21. Dust contained in the air is removed by the dust collection filter 21. The air that has passed through the dust collection filter 21 further passes through the deodorizing filter 22 on the downstream side. An unpleasant odor component contained in the air is adsorbed by the deodorizing filter 22 by the deodorizing filter 22. In addition, a static pressure acts on the whole surface of the air purifying filter 20 by the air that is pushed from the blower chamber R1. The air that has passed through the air cleaning filter 20 is then sent to the humidification chamber R3.

The air sent to the humidification chamber R3 flows upward (see reference numeral f3 in FIGS. 2 and 3). In the humidification chamber R3, an air flow along the outer surface (outer wall) of the tank 31 occurs. Further, the air flow f3 is guided by the rectifying plate 36 so as to pass through the humidifying filter 33a. Thereby, the air that has flowed into the humidifying chamber R3 flows in the thickness direction of the air purification filter 20 (see reference numeral f3), and then branches toward the two humidifying elements 33 (see reference numeral f4 in FIG. 2). That is, the flow direction of the air flowing in the direction orthogonal to the thickness direction of the humidifying element 33 after passing through the air purification filter 20 is changed by the flow of the air in the humidifying chamber R3 along the tank 31. It bends in the thickness direction of the humidifying element 33 (the axial direction of the rotor rotation shaft 33d). Thereafter, the air passes through the humidifying element 33, flows along the outer wall of the tank 31, and is blown out from the outlet 11b (see reference numeral f5 in FIGS. 2 and 3).

In addition, if the humidification function is set to ON when the power source of the air cleaner 10 is set to ON, the humidification element 33 rotates. Since the lower portion of the humidifying filter 33a is immersed in the water of the tray 32, the portion of the humidifying filter 33a that is newly immersed in the water sucks up the water of the tray 32 by rotating the humidifying element 33. Further, by the rotation of the humidifying element 33, the water drawing section 33 c draws up the water in the tray 32 and sprinkles the humidifying filter 33 a near the uppermost point of the humidifying element 33. As a result, water spreads throughout the humidifying filter 33a. That is, when the humidification function is set to ON, the air that has entered the humidification chamber R3 from the air cleaning chamber R2 promotes vaporization of the water that has soaked into the humidification element 33. Thereby, air turns into humid air. The humidified air is then blown out from the air outlet 11b. On the other hand, if the humidifying function is set to off when the power of the air cleaner 10 is set to on, the humidifying element 33 does not rotate. That is, the air is blown out from the air outlet 11b without being sufficiently humidified.

(4) Air Clean Filter Attaching / Removing Operation Next, the air purifying filter 20 removing operation will be described with reference to FIGS. 7 and 8. Each of FIGS. 7 and 8 sequentially represents an operation (removal operation) for removing the air purification filter 20 from the casing 11. Specifically, FIGS. 7A to 7D show the process of the removal operation using the perspective view of the air cleaner 10, and FIGS. 8A to 8D show the air cleaner 10 of FIG. The process of the detachment operation is shown using a schematic configuration diagram of II-II section of FIG. Each of FIGS. 7A to 7D corresponds to FIGS. 8A to 8D. The operation of attaching the air purification filter 20 to the casing 11 is performed in the reverse process of the removal operation.

7 (a) and 8 (a) show the air purifier 10 before the start of maintenance. At the start of maintenance, as shown in FIGS. 7B and 8B, the door 11c is first opened. Specifically, the door 11 c is removed from the casing 11. As a result of removing the door 11c, the opening 15 is opened (see FIG. 7B). By removing the door 11c, the tank 31 attached to the door 11c is also removed from the casing 11. Here, the tank 31 is removed from the casing 11 by lifting the door 11c upward. The tank 31 may be removed from the casing 11 by pulling out the door 11c to the front side.

Thereafter, as shown in FIGS. 7C and 8C, the tray 32 is removed from the casing 11. Specifically, the tray 32 is pulled out to the near side using the handle 32d. At this time, the humidifying element 33 is taken out of the casing 11 through the opening 15. As a result, a wide space is formed above the casing 11. In other words, by removing the tray 32 and the humidifying element 33 from the casing 11, a space in which the air purifying filter 20 can be moved is formed in the humidifying chamber R3.

Thereafter, the air purification filter 20 is removed from the casing 11 as shown in FIGS. The air purification filter 20 is moved in the thickness direction of the filter and taken out from the flange portion 11d, and then moved in the humidification chamber R3 and removed from the casing 11. In other words, the air purification filter 20 is pulled up toward the downstream side in the air flow direction, and then taken out of the casing 11 through the opening 15.

(5) Features (5-1)
The air cleaner 10 according to the embodiment includes an air cleaning filter 20, a humidification unit 30, a fan (blower fan) 12 a, and a casing 11. The air cleaning filter 20 removes dust contained in the air. The humidification unit 30 vaporizes the supplied water and humidifies the air. The air blower 12 blows air toward the air purification filter 20 and the humidification unit 30. In detail, the air blower 12 ventilates with respect to the air purifying filter 20 and the humidification filter 33a. The casing 11 houses the humidification unit 30, the air purification filter 20, and the blower 12. The casing 11 has an opening 15 for attaching / detaching the humidifying unit 30. The humidifying unit 30 is arranged side by side on the downstream side of the air purification filter 20 in the removal direction of the air purification filter 20. The opening 15 allows the air purification filter 20 to be removed after the humidification unit 30 is removed.

Generally, when an air cleaner includes a humidifying unit, the air cleaner is provided with an opening for attaching / detaching the humidifying unit and an opening for attaching / detaching the air purifying filter. The opening for attaching and detaching the air purification filter is formed on the side surface of the casing so that the air purification filter can be inserted in a direction orthogonal to the air flow direction. The opening for attaching and detaching the humidifying unit is formed largely on the side surface of the casing in order to allow the tank to be removed. A lid (door) is provided at the opening in order to ensure the airtightness of the casing. Therefore, when an air cleaner is provided with a humidification unit, it is necessary to provide a door for each of the opening for attaching / detaching the air cleaning filter and the opening for attaching / detaching the humidifying unit. Although it is possible to secure a certain degree of airtightness by providing a door in the opening, an increase in the number of openings is not preferable when high airtightness is required.

Therefore, in the air cleaner 10 according to the above embodiment, the opening 15 for attaching / detaching the humidifying unit 30 is also used as the opening 15 for attaching / detaching the air cleaning filter 20. Specifically, the humidifying unit 30 is disposed on the downstream side of the air purification filter 20 in the removing direction of the air purification filter 20. The air purification filter 20 can be removed from the casing 11 through the same opening 15 after the humidification unit 30 is removed through the opening 15. That is, one opening can be used for both attachment / detachment of the humidifying unit 30 and attachment / detachment of the air purification filter 20. As a result, the number of openings can be suppressed. Therefore, high airtightness can be obtained. Further, since it is not necessary to provide a plurality of openings and doors, the number of manufacturing steps can be reduced.

(5-2)
In the air cleaner 10 according to the above embodiment, the removal direction of the air purification filter 20 is the thickness direction of the air purification filter 20. That is, the air purification filter 20 is removed in the thickness direction of the air purification filter 20.

As described above, in the conventional air purifier, the air purifying filter is inserted from the side of the casing so as to be orthogonal to the air flow direction. When providing an air purification filter, in order to improve the airtightness of the air purification filter with respect to a casing, it is common to provide a sealing member. The seal member is disposed along the outer shape of the air purification filter. Here, when the air purifying filter is inserted from the side of the casing, the seal member is rubbed and worn with the casing or the air purifying filter when the air purifying filter is removed. As a result, it becomes difficult to ensure a certain airtightness for a long time.

Also in the air cleaner 10 according to the above-described embodiment, a sealing member is used to improve the airtightness with respect to the air cleaning filter 20. However, in the air cleaner 10 according to the above embodiment, the air purification filter 20 is removed in the thickness direction of the air purification filter 20. Therefore, wear of the air purification filter when the air purification filter 20 is attached or detached can be suppressed. As a result, a certain airtightness can be ensured for a long time.

In the air cleaner 10 according to the above embodiment, the air purification filter 20 can be removed using a large space formed after the humidification unit 30 is removed. Thereby, removal of the air purifying filter 20 can be made easy.

(5-3)
The air cleaner 10 according to the above embodiment has sealing means (the flange portion 11d and the sealing member 11e) for sealing the gap between the air cleaning filter 20 and the casing 11 on the upstream side of the air cleaning filter 20 in the removing direction. Further prepare. Specifically, as shown in FIGS. 2 and 3, the air purification filter 20 is formed on a flange portion 11 d formed inside the casing 11 and a seal member 11 e arranged in a plane on the flange portion 11 d. Placed. Thereby, shakiness of the air purification filter 20 with respect to the casing 11 can be suppressed.

(5-4)
In the air cleaner 10 according to the above embodiment, the humidifying unit 30 humidifies the air by humidifying the tank 31 that stores water, the tray 32 that receives water from the tank 31, and the water supplied from the tray 32. And a filter 33a. When the humidifying unit 30 is removed from the casing 11, a large space is formed in the casing 11 above the air purification filter 20. Therefore, a sufficient space for removing the air purification filter 20 can be ensured during maintenance of the air cleaner 10. In addition, the air purifying filter 20 can be suppressed by the humidifying unit 30 during the operation of the air purifier 10. Thereby, the stability of the air purifying filter 20 can be ensured.

(6) Modifications Modifications of the above embodiment will be described below. In the modification, the configuration described in the above embodiment will be described using the same reference numerals.

(6-1) Modification 1A
In description of the air cleaner 10 which concerns on the said embodiment, although the direction in which the door 11c was provided was demonstrated as a front side (front side), the front of the air cleaner 10 may be any direction. For example, the direction in which the control panel 13 is provided may be the front.

(6-2) Modification 1B
As for the air cleaner 10 which concerns on the said embodiment, the blower outlet 11b is provided in the upper end part (ceiling part) of the casing 11, as shown in FIG. Moreover, when the door 11c is removed, the part (frame body) which comprises the blower outlet 11b remains in the upper end part of the casing 11 (refer Fig.7 (a), (b)).

Here, as shown in FIG. 9, you may employ | adopt the air cleaner 100 with which the outlet grill 11g was attached to the casing 11. As shown in FIG. Specifically, in the air cleaner 100, a blowout grill 11 g is attached to the upper end of the casing 11. The blower outlet 11b is formed in the blower outlet grill 11g (refer Fig.9 (a)). When the blowout grill 11g is lifted upward, the upper end of the casing 11 is opened as shown in FIG. 9B. Thereafter, as shown in FIG. 9C, the tank 31 is removed together with the door 11c. As a result, the upper part on the front side of the casing 11 is also opened. That is, a large opening 15 is formed in the casing 11 from the upper end of the casing 11 to the upper part on the front side.

The scroll casing 512c forms an air passage for guiding the air blown out by the fan 512a to the first opening K1 located above the fan 512a.

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

Since air is blown out in the centrifugal direction from the plurality of blades 512ab as described above, the dust collection filter 521 of the air cleaning filter 520 is not upward, as indicated by the one-dot chain line arrow in FIG. Air flows obliquely upward.

(2-3) Air Purifying Filter The air cleaning filter 520 cleans the air sucked into the air purifier 510. Specifically, the air cleaning filter 520 removes dust contained in the air. The air cleaning filter 520 removes components that cause odors.

The air cleaning filter 520 is disposed in the air cleaning chamber S2 (see FIG. 22). The air purifying filter 520 is disposed above the air blower 512 and is disposed below the humidifying unit 530 (see FIG. 22). In addition, the air purification filter 520 is disposed on the downstream side of the blower 512 and is disposed on the upstream side of the humidification unit 530 in the air flow direction.

The air cleaning filter 520 mainly includes a dust collection 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 components that cause odors contained in the air.

The deodorizing filter 522 is disposed above the dust collection filter 521. In other words, the deodorizing filter 522 is disposed downstream of the dust collection filter 521 in the air flow direction.

The thickness direction of the dust collection filter 521 and the deodorizing filter 522 is the vertical direction. In other words, the air purification filter 520 has the vertical direction as the thickness direction. Air passes through the air cleaning filter 520 mainly in the thickness direction. In other words, the air purification filter 520 is disposed so that the air purification filter 520 (the dust collection filter 521 and the deodorization filter 522) spreads in a direction orthogonal to the air passage direction.

(2-3-1) Dust Collection Filter The dust collection filter 521 is a filter for removing fine dust that has not been 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 which is folded at a plurality of folds 521a and formed with a plurality of “pleats” is used (see FIG. 25). When the dust collection filter 521 is cut along a cross section orthogonal to the fold line 521a, the cross section is formed into a shape having a plurality of continuous peaks and valleys. By using the pleated filter, a larger surface area (ventilation area) of the dust collection filter 521 can be secured with the same installation area than in the case of using a filter on a flat plate on which “pleats” are not formed.

In the dust collection filter 521, the direction in which the pleat filter fold 521a extends and the direction in which the tongue 512ca of the scroll casing 512c of the blower 512 extends, in other words, the direction of the rotation axis of the fan 512a of the blower 512, are orthogonal. Thus, it is placed on the flange portion 511e (see FIG. 24).

As described above, the dust collection filter 521 of the air cleaning filter 520 is mounted on the flange portion 511e formed inside the casing 511. In other words, the dust collection filter 521 of the air purification filter 520 is held in the casing 511 by the flange portion 511e. The flange portion 511e is in contact with the lower surface 521ba of the peripheral edge portion 521b (see FIG. 25) through which the air of the dust collection filter 521 does not pass (see FIG. 21), so that a clearance between the air cleaning filter 520 and the inner wall of the casing 511 is obtained. It functions as a sealing means for sealing. The sealing means ensures the sealing performance between the air cleaning filter 520 and the casing 511 when air is sent from the blower chamber S1 to the air cleaning chamber S2. The flange portion 511e is disposed on the upstream side of the air purification filter 520 in the air flow direction. In other words, the sealing means is disposed on the upstream side of the air purification filter 520 in the removal direction of the air purification filter 520. The attachment / detachment of the dust collection filter 521 to the casing 511 will be described later.

(2-3-2) Deodorizing Filter The deodorizing filter 522 is a filter that removes components that cause odors contained in air. The deodorizing filter 522 is a filter formed in a rectangular shape.

The deodorizing filter 522 is accommodated in a filter case 523 described later as shown in FIGS. The deodorizing filter 522 is configured to be detachable from the filter case 523. The attachment state of the filter case 523 to the casing 511 and the attachment / detachment of the deodorizing filter 522 (filter case 523) to the casing 511 will be described later. A filter detection sensor 525 for confirming the presence or absence of the deodorizing filter 522 will also be described later.

(2-4) Filter Case The filter case 523 accommodates the air cleaning filter 520. Specifically, the filter case 523 accommodates a deodorizing filter 522 that is a part of the air purification filter 520 (see FIG. 26).

The filter case 523 is a rectangular ring-shaped member and houses the deodorizing filter 522 inside. The filter case 523 has a side wall portion 523b having a substantially C-shaped cross section that surrounds and holds the peripheral edge portion of the accommodated deodorizing filter 522 from above and below and from the side (outer peripheral side) (see FIGS. 21 and 22). That is, the inner peripheral side of the side wall part 523b is open. The entire periphery of the deodorizing filter 522 is surrounded by the side wall portion 523b. The upper and lower surfaces of the filter case 523 are greatly opened, and the air that has passed through the dust collection filter 521 passes through the deodorizing filter 522 accommodated in the filter case 523 from below and blows out upward of the deodorizing filter 522.

A convex portion 523 a that engages with a concave portion 511 g provided on the inner wall of the casing 511 is provided on the right surface of the side wall portion 523 b of the filter case 523. The convex portions 523a are provided at two locations on the right surface of the side wall portion 523b. In addition, the number of the convex parts 523a is an example, and is not limited thereto, and may be determined as appropriate. The number of the recesses 511g provided on the inner wall of the casing 511 may be appropriately determined according to the number of the protrusions 523a. Each convex portion 523a is formed so as to fit into one of two concave portions 511g (see FIG. 25) provided in the casing 511.

In a state where the filter case 523 is attached to the casing 511, the convex portion 523a is engaged with the concave portion 511g, and the left side of the filter case 523 is placed on a support portion 511f provided inside the casing 511. In other words, in a state where the filter case 523 is attached to the casing 511, the filter case 523 is supported from below by the concave portion 511g into which the convex portion 523a is fitted and the support portion 511f. When the filter case 523 is attached to the casing 511, the deodorizing filter 522 is attached to the casing 511 in a horizontal state, in other words, in a state where the thickness direction of the deodorizing filter 522 coincides with the vertical direction. The attachment / detachment of the filter case 523 to / from the casing 511 will be described later.

A notch 523ba in which the side wall 523b is notched is formed at the left side center of the side wall 523b of the filter case 523 (see FIG. 26). In the cutout portion 523ba, the side wall portion 523b is cut out with the upper side (the upper surface and the upper side of the side surface) left (see FIG. 26). In a state where the deodorizing filter 522 is accommodated in the filter case 523, the deodorizing filter 522 is exposed at the notch 523ba.

The filter case 523 includes an airflow guide 524 disposed above the air cleaning filter. The airflow guide 524 is formed integrally with the filter case 523.

The airflow guide 524 is provided on the upper left side of the filter case 523 (see FIG. 22). The airflow guide 524 is provided above the first opening K 1 formed in the casing 511. The airflow 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 diagonally upward and right from the left side wall portion 523b (see FIG. 27). The 1st guide surface 524b is a curved surface for guiding the air which passed the deodorizing filter 522 of the air purifying filter 520 to the humidification element 533 of the humidification unit 530 mentioned later. By forming the first guide surface 524b with a smooth curved surface, the air that has passed through the deodorizing filter 522 can be guided to the second opening K2 and further to the humidifying element 533 while suppressing an increase in pressure loss. The vertical surface 524a of the airflow guide 524 passes upward through the gap before and after the first guide surface 524b of the airflow guide 524, and the air that has passed through the deodorizing filter 522 faces upward, and the gap between the casing 511 and a humidifying tray 532 described later. To flow out of the casing 511. The vertical surface 524 a and the first guide surface 524 b mainly guide the air that has passed through the left side of the deodorizing filter 522 to the humidifying element 533.

On the upper part of the airflow guide 524, a recess 524d formed so as to be recessed downward is provided (see FIG. 27). The recess 524d is formed not only below but also below the upper surface 524c on the left side of the airflow guide 524 (see FIG. 27). The recess 524d functions as a handle that the user grips when attaching / removing the filter case 523.

In a state where the air purifying filter 520 and the humidifying unit 530 are attached to the casing 511, the upper surface 524c of the airflow guide 524 (see FIGS. 26 and 27) is in contact with the lower surface 532b of the humidifying tray 532 of the humidifying unit 530 described later (see FIG. 22). For this reason, even if air is blown from the blower 512 and a force that lifts (moves upward) the air purification filter 520 acts, the humidifying tray 532 restricts the upward movement of the air purification filter 520. That is, the lower surface 532 b of the humidifying tray 532 functions as a movement restricting unit that restricts the upward movement of the air purification filter 520.

(2-5) Filter Detection Sensor The filter detection sensor 525 (see FIG. 22) is a sensor that detects whether or not the air purifying filter 520 is attached to the casing 511. Specifically, the filter detection sensor 525 is a sensor that detects whether or not the deodorizing filter 522 of the air purification filter 520 is attached to the casing 511.

The filter detection sensor 525 mainly includes a detection lever 525a and a detection switch 525b (see FIGS. 28A and 28B). The detection lever 525a is configured to be rotatable around a rotation shaft 525c (see FIGS. 28A and 28B). One end of the detection lever 525a has a contact arm 525d that extends in a direction crossing the direction in which the detection lever 525a extends and contacts the deodorizing filter 522. A detection switch that contacts the detection switch 525b at the other end of the detection lever 525a (the end on the side where the contact arm 525d is provided is the end disposed on the opposite side of the rotation shaft 525c). A contact portion 525aa is provided. Here, the contact arm 525d extends in an arc shape from the detection lever 525a. However, the contact arm 525d is not limited to this, and the contact arm 525d may be formed to extend perpendicular to the extending direction of the detection lever 525a. Good.

The detection lever 525a is configured such that a force acts in one direction around the rotation shaft 525c (so that the detection switch contact portion 525aa is separated from the detection switch 525b) by a torsion spring (not shown). In a state where the contact arm 525d is not in contact with the deodorizing filter 522 (a state where the deodorizing filter 522 is not accommodated in the filter case 523), the notch 523ba of the filter case 523 is passed through as shown in FIG. Thus, the contact arm 525d protrudes into the filter case 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 a state where the deodorizing filter 522 is not accommodated in the filter case 523, a signal transmitted when the deodorizing filter 522 is present is not transmitted from the filter detection sensor 525 to the control device (not shown) of the air purifier 510. . In such a state, the control device determines that the deodorizing filter 522 is not attached to the air purifier 510, stops the operation of the air purifier 510, issues a warning that the deodorizing filter 522 is not attached, or the like. Execute the necessary control. Although illustration and description are omitted here, not only the deodorizing filter 522 but also the filter case 523 is not attached to the casing 511, the detection switch contact portion 525aa is not in contact with the detection switch 525b. Thus, the signal transmitted when the deodorizing filter 522 is present is not transmitted to the control device.

On the other hand, in a state where the deodorizing filter 522 is accommodated in the filter case 523, the contact arm 525d contacts the deodorizing filter 522 at the notch 523ba of the side wall 523b of the filter case 523. The detection lever 525a overcomes the force of a torsion spring (not shown) and rotates in a direction in which the detection switch contact portion 525aa of the detection lever 525a contacts the detection switch 525b. When the detection switch contact portion 525aa comes into contact with the detection switch 525b, the detection switch 525b is turned on, and a signal transmitted when the deodorizing filter 522 is present is transmitted from the filter detection sensor 525 to the control device of the air purifier 510. . When it is determined that the deodorizing filter 522 is attached to the air cleaner 510, the control device permits the operation of the air cleaner 510 if there is no other abnormality.

In addition, although this air cleaner 510 is provided only 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, 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 to detect the presence or absence of the dust collection filter 521. However, as will be described later, in the present air cleaner 510, when the dust collection filter 521 is not present, it is difficult to attach the filter case 523 containing the deodorization filter 522. It is possible to detect a state where the dust collection filter 521 is not attached only by detection.

(2-6) Humidification unit The 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 downstream of blower 512 and air purification filter 520 in the air flow direction. That is, the humidification unit 530 humidifies the air cleaned by the air cleaning filter 520. The humidification unit 530 is a rotary humidification unit. In the humidifying unit 530, the peripheral edge of the humidifying element 533 is rotated so as to pass through the water stored in the humidifying tray 532, which will be described later, and the air is vaporized by vaporizing the water from the humidifying element 533 containing water. Humidify.

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

The humidification unit 530 mainly includes a humidification tank 531, a humidification tray 532, and a humidification element 533 as shown in FIGS. 22 and 23. Further, the humidifying unit 530 has a humidifying motor 534 for rotationally driving the humidifying element 533 (see FIG. 22). The humidifying motor 534 is installed in the casing 511. On the other hand, the humidification tank 531, the humidification tray 532, and the humidification element 533 are comprised so that removal from the casing 511 is possible.

(2-6-1) Humidification Tank The humidification tank 531 stores water to be supplied to the humidification element 533. The humidification tank 531 is formed integrally with the first side plate 511c of the casing 511. Therefore, the humidification tank 531 is configured to be detached from the humidification unit 530 (humidification tray 532) by removing the first side plate 511c from the casing 511 (see FIG. 32B).

The humidification tank 531 is arranged on the left side of the humidification tray 532. Since the humidifying tray 532 is disposed on the left side of the casing 511, the humidifying tank 531 is disposed on the left side of the casing 511.

In the air cleaner 510, the fan motor 512b of the blower 512, which is a heavy object, is disposed on the right side of the casing 511 as described above (see FIG. 22). On the other hand, the humidification tank 531 which is a heavy article is arrange | positioned at the left side of the casing 511 (refer FIG. 22). That is, the fan motor 512b is shifted to one side (right side) with respect to the center of the air purification filter 520, and the humidification tank 531 is opposite to the one side with respect to the center of the air purification filter 520. It is shifted to the side (left side). Thus, since the heavy weight fan motor 512b and the humidification tank 531 are not biased to the same side in the top view and are separated in the opposite directions, the air cleaner 510 has a good weight balance.

The humidification tank 531 has a water inlet 531a. A water supply valve (not shown) is attached to the water injection port 531a. Since the water supply valve has a general structure in which the valve body is pressed against the valve opening by a spring, detailed description of the water supply valve is omitted here.

The humidification tank 531 is arranged in a tank receiving portion 532c, which will be described later, on the left side of the humidification tray 532 when used. Specifically, the humidifying tank 531 is attached to the tank receiving portion 532c of the humidifying tray 532 with the water inlet 531a facing downward. When the humidifying tank 531 is mounted on the tank receiving portion 532c, a pushing pin (not shown) provided on the humidifying tray 532 is pressed against the water supply valve of the water injection port 531a facing downward. Then, due to the weight of the humidifying tank 531, the water supply valve is pushed by the push-in pin, the valve port is pushed open, and the water injection port 531a is opened. As a result, water is supplied to a humidifying tray 532 described later, and water for immersing the humidifying element 533 is accumulated up to a predetermined height of the humidifying tray 532.

The humidification tank 531 has a generally rectangular shape when viewed from the right side (see FIG. 21). Further, when viewed from the front side, the humidifying tank 531 is formed in a planar shape extending substantially in the vertical direction on the left side (see FIG. 22). Further, when viewed from the front side, the humidifying tank 531 has a curved surface on the right side (see FIG. 22). The right side surface 531b (see FIG. 22) formed in the curved shape of the humidifying tank 531 functions as a guide surface that guides the air that has passed through the humidifying element 533 to the air outlet 511b. Specifically, the lower portion of the right side surface 531b (right side lower portion 531ba) is a curved surface that is recessed to the lower left side. The right side lower portion 531ba is a curved surface formed so as to be higher toward the left side (see FIG. 22). The lower right side surface 531ba is a curved surface whose inclination changes so that the inclination is closer to the left side (see FIG. 22). The upper part (right side upper part 531bb) of the right side 531b is a vertical plane smoothly connected to the lower right side 531ba (see FIG. 22). By forming the right side surface 531b in such a shape, the air that has passed through the humidifying element 533 obliquely upward to the left is guided to the air outlet 511b in the upper portion 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 supplied to the humidifying element 533 described later is stored in the humidifying tray 532. The second side plate 511 d of the casing 511 also serves as the left side wall of the humidifying tray 532.

The humidifying tray 532 is disposed below the humidifying element 533 (see FIG. 22). As shown in FIG. 22, the humidifying tray 532 is generally U-shaped when viewed from the side (front side in FIG. 22). The humidifying tray 532 is disposed on the left side of the casing 511 (see FIG. 22). A second opening K2 is formed between the right side wall of the humidifying tray 532 and the inner wall of the casing 511 (see FIG. 22).

The humidifying tray 532 has a curved second guide surface 532a that guides the air that has passed through the air cleaning filter 520 to the humidifying element 533 at the lower corner on the right side of the humidifying tray 532 (see FIG. 22). In other words, the humidifying tray 532 has a curved second guide surface 532a that guides the air that has passed through the air cleaning filter 520 to the humidifying element 533 at the lower corner of the humidifying tray 532 adjacent to the second opening K2. (See FIG. 22). Specifically, curved processing is applied to the lower corner of the humidifying tray 532 on the right side.

The first guide surface 524b and the second guide surface 532a of the airflow guide 524 described above draw a continuous curve with a slight gap G generated between the airflow guide 524 and the humidifying tray 532 interposed therebetween. The lower surface 532b of the humidifying tray 532 functions as a movement restricting unit that restricts the upward movement of the air cleaning filter 520 in a state where the humidifying unit 530 and the air cleaning filter 520 are attached in the casing 511. In other words, the lower surface 532b of the humidifying tray 532 serving as the movement restricting unit is in contact with the upper surface 524c of the airflow guide 524 and restricts the upward movement of the air cleaning filter 520. Therefore, the gap generated between the airflow guide 524 and the humidifying tray 532 is very narrow. Therefore, most of the air passing through the deodorizing filter 522 and guided by the first guide surface 524 b is guided to the humidifying element 533 by being guided by the second opening K 2. In other words, most of the air guided by the first guide surface 524b flows through the gap between the airflow guide 524 and the humidifying tray 532, and the casing 511 from the gap between the first side plate 511c, the second side plate 511d, and the casing 511 or the like. It does not leak out.

The humidifying tray 532 has a tank receiving portion 532c that receives the humidifying tank 531 on the left side (see FIG. 23). A humidifying tank 531 with the water injection port 531a facing downward is disposed in the tank receiving portion 532c (see FIG. 22). The water supply valve of the water inlet 531a of the humidifying tank 531 attached to the tank receiver 532c is pressed against a push pin (not shown) provided on the tank receiver 532c. Then, due to the weight of the humidification tank 531, the water supply valve is pushed by the push-in pin, the valve port is pushed open, the water injection port 531a is opened, and water is supplied to the humidification tray 532.

The water supplied from the humidification tank 531 is supplied to the water supply unit 532d on the right side of the humidification tray 532 (see FIG. 23). The water supply unit 532d is disposed below the humidifying element 533 (see FIG. 22). The water supply part 532d is a part that supplies water supplied from the humidification tank 531 to the humidification element 533 in the tank receiving part 532c.

The water supply unit 532d and the tank receiving unit 532c are partitioned by a partition wall (not shown). A notch is formed in the partition wall, and the water supplied from the humidifying tank 531 to the tank receiving portion 532c is sent to the water supply portion 532d through the notch. That is, the water supplied to the tank receiving portion 532 c disposed on the left side of the casing 511 is then sent to the water supply portion 532 d on the right side of the casing 511. In order to immerse the humidifying element 533 in the water supply unit 532d, water is stored up to a predetermined water level. The water level of the water supply unit 532d is automatically adjusted so that the water level is maintained at a predetermined level when there is water in the humidification tank 531.

The humidifying tray 532 has a bearing portion 532e (see FIG. 29). The bearing portion 532e rotatably supports a rotor rotating shaft 533c (see FIG. 29) of a humidifying element 533 described later. The bearing portion 532e is configured such that the rotor rotation shaft 533c is detachable so that the humidifying element 533 can be removed during maintenance or the like. Specifically, the bearing portion 532e is formed in a U-shape that opens upward, and the rotor rotation shaft 533c can be attached / detached from the U-shape opening (see FIG. 29). ).

One guide pin 532f is provided on each of the front and rear side surfaces of the water supply unit 532d of the humidifying tray 532 (see FIG. 29). When the humidifying tray 532 is attached to the casing 511, the guide pin 532f is fitted into the C-shaped guide 511i (see FIG. 29) provided on the inner walls before and after the casing 511 from the C-shaped opening. When the humidifying tray 532 is pushed into the casing 511, the humidifying tray 532 is easily set at a predetermined position.

(2-6-3) Humidification element The humidification 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 and vaporizes the supplied water to humidify the air.

The humidifying element 533 is disposed on the right side of the humidifying tray 532. Specifically, the humidifying element 533 is disposed above the water supply unit 532 d 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 includes a humidifying filter 533a, a humidifying rotor 533b, and a rotor rotating shaft 533c (see FIG. 29).

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

The humidification rotor 533b is a frame that surrounds the outer peripheral edge of the humidification filter 533a and holds the humidification filter 533a. The humidification rotor 533b is connected to a rotor rotation shaft 533c disposed at the center of the humidification rotor 533b.

The rotor rotating shaft 533c is rotatably supported on one side (left side) by a bearing portion 532e provided on the humidifying tray 532. A hexagonal connecting portion 533d is formed on the other side (right side). In addition, a distal end portion 533e that is continuous with the connecting portion 533d and is formed so as to be thinner toward the end portion is formed at the right end portion.

When the humidifying tray 532 is attached to the casing 511, the rotor rotating shaft 533c is inserted into the hole 534ba of the connection receiving portion 534b of the humidifying motor 534 described later from the front end portion 533e (see FIG. 29). The rotor rotating shaft 533c is inserted into the hole 534ba until the connecting portion 533d reaches the connecting receiving portion 534b, whereby the connecting portion 533d and the connecting receiving portion 534b are connected. Specifically, the hole 534ba of the connection receiving portion 534b is a hexagonal hole substantially the same as the outer shape of the connection portion 533d, and the connection portion 533d is inserted into the hole 534ba formed in the connection reception portion 534b. The connection portion 533d is fitted to the connection receiving portion 534b, and both are connected. By connecting the connection receiving portion 534b and the connection portion 533d, the rotor rotation shaft 533c and the drive shaft 534a of the humidifying motor 534 described later are connected. When the humidification motor 534 is driven and the drive shaft 534a rotates, the rotor rotation shaft 533c also rotates. Here, since the connecting portion 533d and the hole 534ba of the connecting receiving portion 534b are formed in a hexagonal shape, the connecting receiving portion 534b rotates freely with respect to the connecting portion 533d when the drive shaft 534a rotates. Rotate without.

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

When a rotational driving force is transmitted from a humidifying motor 534 described later to the rotor rotating shaft 533c and the humidifying element 533 is rotated, the peripheral edge of the humidifying filter 533a of the humidifying element 533 is accumulated in the water supply portion 532d of the humidifying tray 532. Pass through. When the peripheral portion of the humidifying filter 533a passes through the water accumulated in the water supply unit 532d of the humidifying tray 532, the humidifying filter 533a receives the supply of water from the water supply unit 532d. As the humidifying element 533 rotates, the air that has been blown by the blower 512 (air that has passed through the air cleaning filter 520) is supplied to the humidifying filter 533a that has moved above the water supply unit 532d. When the air passes through the humidifying filter 533a, the water contained in the humidifying filter 533a is vaporized, whereby the air is humidified.

(2-6-4) Humidification Motor The humidification motor 534 is a motor for driving the humidification element 533 to rotate.

The humidifying motor 534 is installed 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 humidifying motor 534 is configured to transmit a driving force to the driving shaft 534a (see FIG. 22). When the humidifying 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 rotation shaft 533c. 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 rotation shaft 533c can be inserted. As described above, the connecting portion 533d of the rotor rotation shaft 533c is inserted into the hole 534ba, whereby the drive shaft 534a and the rotor rotation shaft 533c are connected.

(3) Operation of Air Cleaner and Air Flow Hereinafter, the operation of the air cleaner 510 and the air flow accompanying the operation of the air cleaner 510 will be described with reference to FIGS. In FIG. 30 and FIG. 31, the flow of air is indicated by a dashed-dotted arrow.

When the power of the air purifier 510 is turned on, the fan motor 512b of the blower 512 rotates the fan 512a. Since the rotating fan 512a blows out air in the centrifugal direction, the pressure around the rotation axis of the fan 512a decreases, and the air is sucked into the fan suction port located at the center of the fan 512a. As a result, an air flow from the suction port 511a toward the fan suction port located at the center of the fan 512a is generated. That is, as the fan 512a rotates, air is sucked into the blower chamber S1 from the suction port 511a formed at the lower left surface and the lower right surface. At this time, relatively large dust is removed by the pre-filter 511ac disposed in the suction port 511a.

Air blown in the centrifugal direction from the plurality of blades 512ab (see FIG. 24) of the fan 512a of the blower 512 and blown in the centrifugal direction is guided to the first opening K1 by the scroll casing 512c, and is cleaned from the first opening K1. It is sent into the chamber S2 (see FIG. 30).

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

The air that has passed through the dust collection filter 521 further passes through the deodorizing filter 522 on the downstream side in the air flow direction. The deodorizing filter 522 removes components that cause odors to the deodorizing filter 522.

The air that has passed through the air cleaning filter 520 is then sent to the humidification chamber S3 through the second opening K2. At this time, in particular, the air that has passed through the left side of the deodorizing filter 522 smoothly enters the second opening K2 by the first guide surface 524b of the airflow guide 524 and the second guide surface 532a formed at the lower portion of the humidifying tray 532. (See FIG. 30). As described above, since the upper surface 524c of the airflow guide 524 and the lower surface 532b of the humidifying tray 532 are in contact with each other, a gap is hardly formed between the airflow guide 524 and the humidifying tray 532. The air hardly passes outside the casing 511 through the gap between the opening of the casing 511 and the first side plate 511c or the second side plate 511d. The first guide surface 524b and the second guide surface 532a draw a continuous curve across a slight gap G, and air is smoothly guided to the second opening K2 along this curve (see FIG. 30).

The air sent to the humidification chamber S3 flows upward and is guided to the humidification element 533 by the rectifying plate 511h provided above the casing 511. Since the rectifying plate 511h has two bypass openings 511ha (see FIG. 31), a part of the air (for example, 20% of the air flowing into the humidifying chamber S3) passes through the bypass opening 511ha. Thus, the humidifying element 533 is guided out of the casing 511 without passing through (see FIG. 31). An ion generator 540 is disposed on the surface of the rectifying plate 511h opposite to the humidifying chamber S3, and the plasma ions generated by the ion generator 540 are carried out of the casing 511 together with the air that has passed through the bypass opening 511ha. .

When the humidifying function of the air cleaner 510 is functioning, the humidifying element 533 is rotated by the humidifying motor 534. The humidifying element 533 is disposed in the water supply unit 532d of the humidifying tray 532 so that the lower portion of the humidifying element 533 is immersed in water. Therefore, when the humidifying element 533 rotates, the humidifying filter 533a is newly added to the water. The part to be immersed sucks up the water in the humidifying tray 532. The air passing through the humidifying element 533 promotes vaporization of the water soaked in the humidifying filter 533a. Thereby, air turns into humid air.

The humidified air that has passed through the humidifying element 533 is such that the right side surface 531b of the humidifying tank 531 functions as an air guide surface, so that the air flow in the upper left direction becomes the vertical upward air flow, It blows out from the blower outlet 511b (refer FIG. 30).

In the above description, the case where the humidifying function is set to ON has been described. However, when the humidifying function is set to OFF, the humidifying element 533 does not rotate, and the air passing through the humidifying element 533 is almost humidified. It blows out from the blower outlet 511b, without being carried out.

(4) Removal of Humidification Unit and Air Purification Filter Next, removal of the humidification unit 530 and the air purification filter 520 will be described mainly with reference to FIGS. 32 and 33. FIG. 32 depicts a removal operation for removing the humidification unit 530 and the air purification filter 520 from the casing 511. In FIG. 32, the removal work of the humidification unit 530 and the air purification filter 520 is drawn using a cross-sectional view of the inside of the casing 511 viewed from the front. FIG. 33 depicts a removal operation for removing the humidification unit 530 from the casing 511. In FIG. 33, the removal work of the humidification unit 530 is drawn using the perspective view which looked at the casing 511 from the left front.

FIG. 32 (a) and FIG. 33 (a) show the air purifier 510 before the start of the removal operation of the humidifying unit 530 and the air purifying filter 520. FIG.

When removing the humidifying unit 530 and the air purification filter 520, first, the user holds the handle 511ca of the first side plate 511c, and as shown in FIGS. 32 (b) and 33 (b), the first side plate 511c is removed. The upper part of the first side plate 511c is opened so as to incline to the left. Then, the humidifying tank 531 formed integrally with the first side plate 511c is extracted obliquely to the upper left, whereby the humidifying tank 531 is removed from the casing 511 (see FIGS. 32 (b) and 33 (c)).

Next, as shown in FIGS. 32 (c) and 33 (d), the humidifying tray 532 is removed from the casing 511. Specifically, the user holds the handle 511da provided on the second side plate 511d constituting a part of the humidifying tray 532, and pulls out the humidifying tray 532 toward the front side (left side). At this time, the connecting portion 533 d of the rotor rotating shaft 533 c of the humidifying element 533 is removed from the connecting receiving portion 534 b provided on the drive shaft 534 a connected to the humidifying motor 534. Here, the connecting portion 533d is only inserted into the hole 534ba of the connecting receiving portion 534b, and is not particularly fixed by a fixing member (for example, a screw). Therefore, the connecting portion 533d can be easily pulled from the hole 534ba. Yes (see FIG. 29). Here, since the guide pin 532f provided on the side surface of the humidifying tray 532 moves along the guide 511i formed on the inner surface of the casing 511, the user can smoothly move the humidifying tray 532 horizontally to the left side. It can be pulled out (see FIG. 29).

By removing the humidifying tray 532 in which the humidifying element 533 is mounted on the bearing portion 532e in this manner from the casing 511, the left opening 515 of the casing 511 is greatly opened (FIGS. 32D and 33). (See (d)). Moreover, a wide space is formed in the upper part in the casing 511 from which the humidifying tray 532 is removed. In other words, by removing the humidifying tray 532 and the humidifying element 533 from the casing 511, a space capable of moving the air cleaning filter 520 is secured in the humidifying chamber S3.

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

Finally, as shown in FIG. 32 (e), the dust collection filter 521 of the air purification filter 520 is removed from the casing 511. Specifically, the user lifts the dust collection filter 521 from the flange portion 511e of the casing 511, moves the dust collection filter 521 in the thickness direction (upward direction) of the dust collection filter 521, and then moves the inside of the humidification chamber S3. Remove from 511. In other words, the dust collection filter 521 is lifted toward the downstream side in the air flow direction, and then taken out of the casing 511 through the opening 515.

(5) Attachment of humidification unit and air purification filter Next, attachment of the humidification unit 530 and the air purification filter 520 will be described. Note that, if the drawings in FIG. 32 and FIG. 33 are viewed in the reverse order, the attaching operation of the humidifying unit 530 and the air purifying filter 520 will be drawn, so here the attaching operation of the humidifying unit 530 and the air purifying filter 520 Drawings depicting this state are omitted.

The attachment of the humidification unit 530 and the air purification filter 520 will be described with reference to the state where the air purification filter 520 and the humidification unit 530 are all removed.

First, the dust collection filter 521 of the air cleaning filter 520 is first installed in the casing 511. Specifically, the user inserts the dust collection filter 521 into the humidification chamber S3 through the opening 515 and then moves the dust collection filter 521 downward to place the dust collection filter 521 on the flange portion 511e of the casing 511 (FIGS. 32D and 32D). e)).

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

Specifically, the user inserts the filter case 523 into the humidification chamber S3 from the opening 515 while holding the concave portion 524d of the airflow guide 524 formed integrally with the filter case 523 and lowering the right side. To do. Thereafter, the user slides the filter case 523 while sliding the right side of the lower surface of the filter case 523 to the upper surface 521bb (see FIG. 32D) of the peripheral edge 521b (see FIG. 25) of the dust collection filter 521. Move from the left side to the right side. At this time, the user moves the filter case 523 from the left side toward the right side while gradually lowering the left side of the filter case 523 downward. The filter case 523 is moved rightward on the dust collection filter 521 until the convex portion 523a formed in the filter case 523 is fitted into the concave portion 511g provided in the casing 511. In a state where the convex portion 523a is fitted in the concave portion 511g, the left side of the filter case 523 can be lowered and placed on the support portion 511f. On the other hand, in a state where the convex portion 523a is not fitted in the concave portion 511g, the left side of the filter case 523 interferes with the inner surface of the casing 511, and the filter case 523 cannot be accommodated in the casing 511.

If the filter case 523 is to be attached in a state where the dust collection filter 521 is not attached, there is no structure for supporting the filter case 523 on the lower side, and the convex portion 523a of the filter case 523 is present. There is no structure that guides to the recess 511g. Therefore, if the filter case 523 is attached without attaching the dust collection filter 521, the right side of the filter case 523 easily falls downward as shown in FIG. 34, and the filter case 523 can be attached at the correct position. Have difficulty.

The deodorizing filter 522 accommodated in the filter case 523 is attached to the casing 511, that is, the convex portion 523a of the filter case 523 is fitted into the concave portion 511g of the casing 511, and the left side of the filter case 523 is the support portion 511f. The filter case 523 is in contact with the upper surface 521bb (see FIG. 21) of the peripheral edge 521b (see FIG. 25) of the dust collection filter 521. As will be described later, when the humidifying tray 532 and the humidifying tank 531 are attached to the casing 511, the lower surface 532b of the humidifying tray 532 is in contact with the upper surface 524c of the airflow guide 524 formed integrally with the filter case 523. It is in. The upward movement of the filter case 523 is regulated by the humidifying tray 532 and the humidifying tank 531, and further, the air flow is caused by the filter case 523 and the upper surface 521bb of the peripheral edge 521b of the dust collection filter 521 being in contact with each other. Therefore, even if a force that lifts up the dust collection filter 521 is applied, the upward movement of the dust collection filter 521 is prevented.

When the attachment of the air cleaning filter 520 is completed, the humidifying tray 532 is attached to the casing 511 (see FIGS. 32 (c) and 33 (d)). Specifically, the user grasps a handle 511da provided on the second side plate 511d constituting a part of the humidifying tray 532, and guide pins 532f provided on the humidifying tray 532 are formed on the inner walls of the front and rear of the casing 511. The tip 533e of the rotor rotating shaft 533c of the humidifying element 533 is inserted into the hole 534ba of the connection receiving portion 534b of the drive shaft 534a connected to the humidifying motor 534 (see FIG. 29), the humidifying tray 532 is moved horizontally toward the right. Here, the guide 511i and the connection receiving portion 534b function as a guide, and it is easy to move the humidifying tray 532 in the horizontal direction. When the connecting portion 533d is inserted into the hole 534ba, if the direction of the hexagonal shape of the connecting portion 533d does not match the direction of the hexagonal hole 534ba, the humidifying element 533 is connected to the connecting portion 533d. The direction of the hexagonal shape of the portion 533d and the direction of the hexagonal hole 534ba are rotated so that the connection portion 533d and the connection receiving portion 534b are connected.

When the humidifying tray 532 is attached to the casing 511, the lower surface 532b of the humidifying tray 532 is in contact with the upper surface 524c of the airflow guide 524 formed integrally with the filter case 523. Since the humidifying tray 532 and the upper surface 524c of the airflow guide 524 are in contact with each other, the upward movement of the air purification filter 520 is prevented even if a force that lifts up the air purification filter 520 due to the air flow is applied. It is done. That is, here, the lower surface 532b of the humidifying tray 532 functions as a movement restricting portion that restricts the upward movement of the air purification filter 520.

Finally, the user grips the handle 511ca of the first side plate 511c, and the lower side of the first side plate 511c formed integrally with the humidifying tank 531 is placed in a state where the upper side of the first side plate 511c is inclined leftward. Engage with the upper side of the second side plate 511d (see FIGS. 32 (b) and 33 (b)). Next, the opening 515 of the casing 511 is closed by standing the first side plate 511c so as to be vertical (see FIGS. 32A and 33A).

(6) Features (6-1)
The air purifier 510 according to the embodiment includes an air purifying filter 520, a humidification unit 530, a fan 512a, and a casing 511. The air cleaning filter 520 removes dust contained in the air. The humidification unit 530 vaporizes the supplied water and humidifies the air. The air blower 512 blows air toward the air purification filter 520 and the humidification unit 530. Specifically, the blower 512 sends air to the air purification filter 520 and the humidification filter 533a. Casing 511 houses humidification unit 530, air purifying filter 520, and fan 512a. The casing 511 has an opening 515 for attaching / detaching the humidifying unit 530. The humidification unit 530 is arranged side by side on the downstream side of the air purification filter 520 in the removal direction of the air purification filter 520. The opening 515 allows the air purification filter 520 to be removed after the humidification unit 530 is removed.

In the air cleaner 510 according to the above-described embodiment, the attachment / detachment opening 515 of the humidifying unit 530 is also used as the attachment / detachment opening 515 of the air purification filter 520. Specifically, the humidification unit 530 is disposed downstream of the air purification filter 520 in the direction in which the air purification filter 520 is removed. The air purification filter 520 can be removed from the casing 511 through the same opening 515 after the humidification unit 530 is removed through the opening 515. That is, one opening 515 can be used for both attachment / detachment of the humidifying unit 530 and attachment / detachment of 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. Further, since it is not necessary to provide a plurality of openings and doors, the number of manufacturing steps can be reduced.

(6-2)
In the air cleaner 510 according to the above embodiment, the removal direction of the air purification filter 520 is the thickness direction of the air purification filter 520. That is, here, the removal direction of the air purifying filter 520 is the vertical direction.

In the air cleaner 510 according to the above embodiment, the air purification filter 520 is removed in the thickness direction of the air purification filter 520. Therefore, compared with the case where the air purification filter 520 is pulled out from the casing 511 in the horizontal direction, the air purification filter 520 and the casing 511 are worn (when the sealing material is sandwiched between the air purification filter 520 and the casing 511, the sealing material). Wear) is less likely to occur. As a result, a certain airtightness can be ensured for a long time.

In the air cleaner 510 according to the above embodiment, the air cleaning filter 520 can be removed using a large space formed after the humidifying unit 530 is removed. Thereby, the air purifying filter 520 can be easily removed.

(6-3)
The air purifier 510 according to the above embodiment includes a flange portion 511e as a sealing unit that seals a gap between the air purifying filter 520 and the casing 511 on the upstream side of the air purifying filter 520 in the removing direction.

Specifically, the air purification filter 520 is placed on a flange portion 511e formed inside the casing 511. Thereby, shakiness of the air purifying filter 520 with respect to the casing 511 can be suppressed. Note that a sealing material may be further disposed between the air purification filter 520 and the casing 511.

(6-4)
In the air cleaner 510 according to the embodiment, the humidifying unit 530 includes a humidifying tank 531 for storing water, a tray 532 for receiving water from the humidifying tank 531, and water supplied from the humidifying tray 532, and vaporizes water. And a humidifying filter 533a for humidifying the air.

When the humidification tank 531, the humidification tray 532, and the humidification element 533 of the humidification unit 530 are removed from the casing 511, a large space is formed in the casing 511 above the air purification filter 520. Therefore, a sufficient space for removing the air purification filter 520 can be ensured during maintenance of the air cleaner 510. Further, when the air purifier 510 is in operation, the air purifying filter 520 can be suppressed by the humidifying unit 530. Thereby, the stability of the air purifying filter 520 can be ensured.

(6-5)
In the air cleaner 510 according to the above embodiment, the humidification unit 530 is disposed above the air purification filter 520 in the casing 511. The humidifying unit 530 has a lower surface 532b of the humidifying tray 532 as a movement restricting portion. The lower surface 532 b of the humidifying tray 532 restricts the upward movement of the air purification filter 520 in a state where the humidification unit 530 and the air purification filter 520 are attached in the casing 511.

Here, since the humidification unit 530 regulates the upward movement of the air purification filter 520, the air purification filter 520 can be lifted with a simple configuration without providing a dedicated member for regulating the movement of the air purification filter 520. Can be prevented. Moreover, the number of parts can be reduced as compared with the case where a dedicated member for restricting movement is provided.

(6-6)
The air cleaner 510 according to the above embodiment includes a filter case 523 that houses the air purification filter 520, specifically, the deodorizing filter 522 of the air purification filter 520. The filter case 523 includes an airflow guide 524 that guides the air that has passed through the air purification filter 520 to the humidification unit 530. The lower surface 532b of the humidifying tray 532 is in contact with the upper part of the airflow guide 524 (the upper surface 524c of the airflow guide 524).

Here, since the upper surface 524c of the airflow guide 524 of the filter case 523 is in contact with the lower surface 532b of the humidifying tray 532, the upward movement of the air purification filter 520 is restricted, so that the air purification filter 520 is lifted with a simple configuration. Can be prevented. Further, since the airflow guide 524 and the lower surface 532b of the humidifying tray 532 are in contact with each other, it is difficult for air to pass between the airflow guide 524 and the lower surface 532b of the humidifying tray 532, and the air that has passed through the air cleaning filter 520. Can be prevented from being led to an unintended route.

(6-7)
In the air purifier 510 according to the above embodiment, the air purifying filter 520 includes a deodorizing filter 522 as an example of a first filter and a dust collection filter 521 as an example of a second filter. The dust collection filter 521 is disposed below the deodorization filter 522. The filter case 523 accommodates the deodorizing filter 522. When the deodorizing filter 522 accommodated in the filter case 523 is attached to the casing 511, the filter case 523 slides on the upper surface 521bb of the peripheral edge 521b of the dust collection filter 521. After the deodorizing filter 522 accommodated in the filter case 523 is attached to the casing 511, the filter case 523 comes into contact with the upper surface 521bb of the peripheral edge portion 521b of the dust collection filter 521.

Here, when the deodorizing filter 522 is attached to the casing 511, the upper surface 521bb of the peripheral edge 521b of the dust collection filter 521 is configured to slide the filter case 523 containing the deodorizing filter 522. The attachment of 522 to the casing 511 is easy. In addition, after the deodorizing filter 522 is attached, the filter case 523 comes into contact with the upper surface 521bb of the peripheral edge 521b of the dust collection filter 521, so that the upward movement of the dust collection filter 521 can be restricted.

(6-8)
In the air cleaner 510 according to the above embodiment, the filter case 523 is formed with a convex portion 523a as an example of a case-side convex portion. The casing 511 has a concave portion 511 g as an example of a concave portion on the casing side that fits with the convex portion 523 a formed in the filter case 523 in a state where the deodorizing filter 522 accommodated in the filter case 523 is attached to the casing 511. It is formed.

Here, since the convex part 523a is provided in the filter case 523 and the concave part 511g in which the convex part 523a is fitted is provided in the casing 511, it is easy to attach the deodorizing filter 522 accommodated in the filter case 523 to a predetermined position. It is.

When the filter case 523 is slid on the upper surface 521bb of the peripheral portion 521b of the dust collection filter 521, that is, when the filter case 523 is guided by the upper surface 521bb of the peripheral portion 521b of the dust collection filter 521, the convex portion 523a It is easy to fit the recess 511g. However, when the dust collection filter 521 is not provided (when the filter case 523 cannot be slid on the upper surface 521bb of the peripheral edge portion 521b of the dust collection filter 521), the protrusion 523a and the recess 511g are aligned. It is difficult to fit both. That is, here, when the dust collection filter 521 does not exist, it is difficult to attach the deodorizing filter 522. Therefore, it is easy to prevent forgetting to attach the dust collection filter 521.

(6-9)
The air cleaner 510 according to the embodiment includes a filter detection sensor 525 that detects whether or not the deodorizing filter 522 is attached to the casing 511.

Here, by providing the filter detection sensor 525, forgetting to attach the deodorizing filter 522 can be prevented.

Further, since the air purifier 510 has a configuration in which it is difficult to attach the deodorizing filter 522 when the dust collection filter 521 is not present, the air purifier 520 can be simply detected by detecting the presence or absence of the deodorizing filter 522. It is possible to detect forgetting to attach.

(7) Modification The configuration of the air cleaner 510 of the second embodiment is appropriately set within the range consistent with the configuration of the air cleaner 10 of the first embodiment or the content of the modification of the first embodiment. They may be combined.

Below, the modification of the air cleaner 510 of 2nd Embodiment is shown. In addition, the following modifications may be applied to the air cleaner 10 of 1st Embodiment in the range without a contradiction.

(7-1) Modification 2A
In the above embodiment, the lower surface 532b of the humidifying tray 532 functions as a movement restricting unit that restricts the upward movement of the air purification filter 520, but is not limited thereto. For example, the humidification unit 530 may have a movement restricting portion formed so as to protrude downward from the humidification tray 532. However, by restricting the movement of the air purification filter 520 with the lower surface 532b of the humidifying tray 532, the movement of the air purification filter 520 can be restricted with a simple structure.

(7-2) Modification 2B
In the above embodiment, the lower surface 532b of the humidifying tray 532, which is an example of the movement restricting unit, is in contact with the airflow guide 524 of the filter case 523, but is not limited thereto. For example, the lower surface 532 b of the humidifying tray 532 may be restricted from moving upward of the air cleaning filter 520 by contacting a portion other than the airflow guide 524 of the filter case 523.

Further, for example, the filter case 523 does not have the airflow guide 524, and the lower surface 532b of the humidifying tray 532 comes into contact with the filter case 523 that does not have the airflow guide 524, so that the air cleaning filter 520 moves upward. It may be regulated. However, the airflow guide 524 is preferably provided because the airflow that has passed through the deodorizing filter 522 can be guided to the humidification unit 530 while suppressing pressure loss.

(7-3) Modification 2C
In the above embodiment, the airflow guide 524 is formed integrally with the filter case 523, but is not limited thereto. For example, the airflow guide 524 may be provided on the lower surface 532 b of the humidifying tray 532. In this case, the upward movement of the air cleaning filter 520 may be restricted by causing the airflow guide 524 to function as a movement restricting unit and bringing the lower part of the airflow guide 524 into contact with the upper part of the filter case 523.

However, when the airflow guide 524 is provided on the lower surface of the humidifying tray 532, the airflow guide 524 is preferably formed integrally with the filter case 523 because the opening 515 of the casing 511 needs to be formed larger.

(7-4) Modification 2D
In the above embodiment, the air purification filter 520 includes the deodorization filter 522, but the air purification filter 520 is not limited thereto, and the air purification filter 520 may include only the dust collection filter 521. In this case, the dust collection filter 521 may be configured to be accommodated in the filter case 523. And the lower surface 532b of the humidifying tray 532 may regulate the upward movement of the air purification filter 520 by contacting the upper part of the airflow guide 524 of the filter case 523 that houses the dust collection filter 521.

(7-5) Modification 2E
In the said embodiment, although the air purifying filter 520 contains the dust collection filter 521 and the deodorizing filter 522, it is not limited to this, You may be comprised so that another filter may be further included.

(7-6) Modification 2F
The configuration of the filter detection sensor 525 of the above embodiment is an exemplification, and a sensor to which another principle is applied may be used as the filter detection sensor.

(7-7) Modification 2G
In the above embodiment, the convex portion 523a is provided in the filter case 523, the concave portion 511g is provided in the casing 511, and the convex portion 523a is fitted in the concave portion 511g. However, the present invention is not limited to this.

For example, as shown in FIG. 35, the filter case 523 is provided with a concave portion 523c as an example of a case side concave portion, the casing 511 is provided with a convex portion 511j as an example of a casing side convex portion, and the concave portion 523c of the filter case 523 is provided. The convex portion 511j of the casing 511 may be fitted.

(7-8) Modification 2H
In the above embodiment, the humidifying unit 530 uses a method in which the humidifying filter 533a of the humidifying element 533 is immersed in water in the water supply unit 532d of the humidifying tray 532. However, the present invention is not limited to this.

For example, the humidification rotor hisch system may be adopted for the humidification unit 530.

Specifically, in the humidification rotor-humidification type humidification unit 530, a plurality of shear 533ba are provided on the humidification rotor 533b of the humidification element 533 (see FIG. 36). In the humidification rotor shear method, the humidification filter 533 a is not directly immersed in water, but when the humidification rotor 533 b rotates, the shear 533 ba scoops up water in the water supply unit 532 d of the humidification tray 532. Then, when the humidification rotor 533b further rotates and the shear 533ba moves to the vicinity of the uppermost position, the shear 533ba applies water to the humidification filter 533a, whereby water is supplied to the humidification filter 533a.

The air cleaner according to the present invention is useful as an air cleaner that can easily ensure airtightness in the casing.
