Description

  The present invention relates to an air cleaner, and more particularly to an air cleaner having a humidifying function.

  2. Description of the Related Art Conventionally, there are air purifiers that purify air by removing or decomposing odor components, dust, bacteria, viruses, and the like floating in indoor air. Some of these air purifiers have not only an air purifying function but also a humidifying function for increasing the humidity of room air. Such a humidification function is implement | achieved using the disk-shaped humidification rotor which is disclosed by patent document 1 (Unexamined-Japanese-Patent No. 2009-148305), for example. The air cleaner of Patent Document 1 includes a water tray that stores water and a disc-shaped humidification rotor for discharging the water in the water tray into the air. The humidification rotor is rotated while water from the water tray is supplied to a part of the humidification rotor. The indoor air taken in the air cleaner is humidified when passing through the humidification rotor.

  Since the conventional air cleaner needs to clean the water tray, the water tray is generally configured to be detachable from the air cleaner. In such an air purifier, for example, since locking is performed using the weight of the water tray, a lock mechanism that locks the water tray to the main body when the water tray is attached or detached is formed at the bottom of the main body. As described in Patent Document 1, since the conventional air purifier has a substantially rectangular parallelepiped appearance, in a normal use state, the bottom portion is hidden behind the water tray. The design will not be damaged.

  However, if the air cleaner has a structure in which the casing has a narrowed bottom like an egg shape, for example, and a stand is provided and a part of the bottom is exposed as a stand, the lock mechanism may be visible, and these can be seen. And causes a decline in design. In particular, the members may rub against each other at the time of locking, and the surroundings of the locking mechanism may become dirty. In such a case, the design properties are significantly reduced.

  The subject of this invention is providing the air cleaner which has a humidification function and was excellent in the designability.

An air cleaner according to a first aspect of the present invention includes a main body, a humidifying element, and a water tray. The main body has a main body casing, a stand, a housing, and a lock portion. The stand is connected to the bottom of the main casing. The housing is for forming an internal space in the main body casing. The lock portion is formed on the support surface of the bottom portion that is a part of the lower wall of the housing. The water tray is housed in the housing and has a lower surface and a locked portion. The lower surface is pushed by the support surface. The locked portion is formed on the lower surface. The humidifying element is housed in a housing, disposed in the main body, and serves to provide moisture to the air to be cleaned. The water tray is attached to the main body from the side, and when attached to the main body, the water tray partitions the internal space including the periphery of the humidifying element from the external space and supplies water to the humidifying element. The lower part of the main body casing is shaped like a bowl so that the bottom of the main body casing is narrower than the stand, and the lock part has a top part that slides against the water tray until the locked part abuts against the lock part. The locked portion of the water tray is locked to the lock portion where it does not face the external space when the water tray is attached to the main body.

  According to the air cleaner which concerns on a 1st viewpoint, the lock part is arrange | positioned at the housing for forming the internal space partitioned off from the external space. When the locked portion of the water tray does not face the external space, it is locked by this lock portion. For this reason, when the water tray is mounted, the lock portion and the locked portion are not visible, and at the same time, there is no possibility that scratches due to the lock portion and the locked portion are attached to the design surface located in the external space when the water tray is mounted.

  In addition, the lower part of the main body casing is formed into a bowl shape, so that the lock part is attached to the stand that is necessary by constricting the lower part of the main body casing while giving a compact impression to the viewer of the air cleaner. Since it is not provided, the shape of the stand is kept beautiful. Since the locked portion also enters the housing when the water tray is mounted, it is possible to prevent the stand from being damaged by the locked portion.

  The air cleaner which concerns on the 2nd viewpoint of this invention is an air cleaner which concerns on a 1st viewpoint. WHEREIN: A water tray partitions off between interior space and exterior space, and forms the partition plate for forming interior space with a housing. And the locked part is locked to the lock part on the humidifying element side of the partition plate.

  According to the air cleaner according to the second aspect, the locked portion is locked to the lock portion on the humidifying element side with respect to the partition plate, so that the water tray is pushed toward the internal space and presses the partition plate against the housing. Therefore, it becomes easy to prevent a gap from being generated in the formation of the internal space.

  The air cleaner which concerns on the 3rd viewpoint of this invention is an air cleaner which concerns on the 1st viewpoint or the 2nd viewpoint. WHEREIN: As for a lock part and a to-be-locked part, when a water tray is mounted | worn, a to-be-locked part strikes a lock part In order to shift from the struck state to the state where the mounting is completed, it is configured to be pushed in with a force stronger than the force required until the locked portion abuts against the lock portion.

  According to the air cleaner according to the third aspect, since the resistance increases before mounting due to the locked part hitting the lock part, has the lock part started locking even if the lock part and the locked part are not visible? It is possible to perceive whether or not the user is in the hands.

  An air cleaner according to a fourth aspect of the present invention is the air cleaner according to the third aspect, wherein the locked portion is a slide in which the water tray and the main body slide until the locked portion comes into contact with the lock portion. The lock portion protrudes more toward the main body than the region, and has a top portion that protrudes toward the water tray and slides with the water tray in the sliding region.

  According to the air cleaner according to the fourth aspect, the lockable portion is protruded while the water tray is slid at the protruding top portion of the lock portion, thereby increasing the resistance that can be perceived by human tactile sense. Can be generated.

  The air cleaner which concerns on the 5th viewpoint of this invention is arrange | positioned between a main body and a partition plate in the air cleaner which concerns on either of a 1st viewpoint to the 4th viewpoint, and seals the internal space of a humidification element. A seal member is further provided, and the lock portion has a structure that does not have an opening that passes from the internal space to the external space.

  According to the air cleaner which concerns on a 5th viewpoint, it is preventing that the channel | path of the air leading from internal space to internal space arises by using a sealing member and setting it as the structure which does not have an opening part in a lock | rock part.

  In the air cleaner according to the first aspect of the present invention, when the water tray is attached, the lock part and the locked part are not visible, and when the water tray is attached, scratches or the like due to the lock part and the locked part are located in the external space Since there is no possibility of sticking to the design surface, a beautiful design can be maintained for a long time, and even if it has a humidifying function, it has excellent design properties.

  Moreover, since the lower part of the main body casing is narrowed in a bowl shape, the design can be excellent even in a shape in which a stand is provided.

  In the air cleaner according to the second aspect of the present invention, it is easy to form an internal space without a gap, and it is possible to prevent the humidification function and the air purification function from being lowered.

  In the air cleaner according to the third aspect of the present invention, even if the lock part and the locked part are not visible, it is easy to perceive the start of the lock, and the water tray can be easily attached.

  In the air cleaner which concerns on the 4th viewpoint of this invention, even if it has the structure which is easy to mount | wear with a water tray, it can provide at low cost.

  In the air cleaner according to the fifth aspect of the present invention, no gap is formed between the internal space and the external space, and a reduction in the humidification function and the air purification function can be prevented.

(1) Overview of Air Purifier Configuration and Operation An overview of the overall configuration of an air purifier according to an embodiment of the present invention is shown in FIGS. FIG. 1 is a perspective view seen from the upper right side toward the front of the air cleaner, and FIG. 2 is a perspective view seen from the upper left side toward the back of the air cleaner.

  The air cleaner 10 has an elegant and compact impression like an egg as compared to an air cleaner having a substantially rectangular parallelepiped shape constituted only by a flat surface by constituting many portions of the main body casing 20 with curved surfaces. However, since the main casing 20 alone lacks stability, the air cleaner 10 includes a stand 25 for ensuring stability.

  The air cleaner 10 has a suction port 11 that takes in indoor air and a blower port 12 that blows out humidified air. The suction port 11 includes a front lower suction port 11a and a side suction port 11b.

  FIG. 3 is a conceptual diagram for explaining the flow of dust removal and decomposition and humidification in the air cleaner. The sirocco fan 16 generates an air flow 13 from the inlet 11 to the outlet 12. Dust and odor components are removed from the indoor air sucked from the suction port 11 by the filter unit 14 and humidified by the humidification unit 15. Then, humid air is blown out from the sirocco fan 16.

  The filter unit 14 includes a pre-filter 17A, a HEPA (High Efficiency Particulate Air Filter) filter 17B, and a deodorizing element 17C. First, large dust is removed by the pre-filter 17A that the air cleaner 10 has. Next, finer dust is removed by the HEPA filter 17B. Further, the air that has passed through the HEPA filter 17B is decomposed or adsorbed by formaldehyde, odor components, and the like by the deodorizing element 17C containing activated carbon or the like.

  The humidifying unit 15 includes a humidifying rotor 50, a water tray 40, and the like. The air that has passed through the deodorizing element 17 </ b> C passes through the humidification rotor 50 of the humidification unit 15. When air passes through the humidification rotor 50, moisture is released from the humidification rotor 50 into the air. The humidification rotor 50 receives water from the water tray 40 in order to compensate for moisture that is reduced by being discharged.

  Switching of the operation of the air cleaner 10 having such a humidifying function is performed by an operation panel 19 provided on the upper portion of the air cleaner 10. The operation panel 19 is provided with a switch for operating on / off of the humidifying operation in addition to on / off of the operation of the air purifier 10. The operation panel 19 can switch between an operation mode in which only air cleaning is performed without humidification and an operation mode in which humidification is performed simultaneously with air cleaning.

  In the operation mode in which only air cleaning is performed, the rotation of the humidification rotor 50 is stopped, and water is not supplied to the humidification rotor 50. Therefore, after the humidification rotor 50 is dried, the release of water into the air stops.

(2) Detailed configuration (2-1) Water tank The outer surface of the air cleaner 10 is covered with the main body casing 20. As shown in FIG. 4, a water tank 30 is accommodated on the left side of the air cleaner 10. The main body casing 20 is configured such that the left side plate 21 can be removed, and a water tank 30 is attached to the left side plate 21. Although not shown, a water inlet is provided below the water tank 30.

  In the main body casing 20, a lower left side plate 22 that is curved so as to squeeze the lower side of the air cleaner 10 is disposed below the left side plate 21. This lower left side plate 22 is attached to the water tray 40. When the water tank 30 is attached, the water in the water tank 30 is poured into the water tray 40 from the water inlet below the water tank 30.

  A fan casing 70 in which the sirocco fan 16 shown in FIG. 3 is housed is disposed on the right side of the water tank 30 in the main body casing 20. The fan casing 70 extends upward toward the air outlet 12, and the air outlet of the fan casing 70 coincides with the air outlet 12 of the main body casing 20. A part of the partition plate 45 of the water tray 40 is overlapped with the fan casing 70, and the overlapped portion of the partition plate 45 is in contact with the fan casing 70 without a gap.

  Above the water tank 30 is provided a bulging portion 30a projecting to the right. In a state where the water tank 30 is mounted on the air purifier 10, the bulging portion 30 a pushes the partition plate 45 to prevent a gap from being generated between the partition plate 45 and the fan casing 70.

(2-2) Water Tray The state where the left side plate 21, the water tank 30, and the water tray 40 are removed from the state of FIG. 4 and the sirocco fan is removed together with the fan casing 70 is the state shown in FIG. The water tray 40 is mounted from the external space Sp1 shown in FIG. In FIG. 5, a member on the front side having a honeycomb-shaped opening is a filter support member 80. The pre-filter 17A, the HEPA filter 17B, and the deodorizing element 17C shown in FIG. 3 are attached to the filter support member 80. The filter support member 80 is provided with a stepped portion 85 on the back side. A part of the partition plate 45 is also overlapped with the step portion 85. And about this level | step-difference part 85, the sealing member 90 is affixed on the part on which the partition plate 45 is overlapped. The seal member 90 is formed of a soft foamed plastic such as a sponge having no through hole.

  FIG. 6 shows a state in which the main body casing 20, the water tank 30, and the filter support member 80 excluding the lower left side plate 22 are removed from the state of FIG. FIG. 6 is a perspective view of the air purifier 10 as seen from the front left diagonally upward.

  The water tray 40 mainly includes a water receiving portion 41 disposed under the water tank 30, a rotor immersion portion 42 in which a lower portion of the humidifying rotor 50 is immersed in water, a partition wall 43, a bearing 44, a partition And plates 45 and 46. The bearing 44 that receives the shaft of the humidifying rotor 50 is attached on the side wall of the water tray 40 that constitutes the rotor immersion portion 42.

  The water receiving part 41 and the rotor immersion part 42 are partitioned by a partition wall 43. The partition wall 43 is provided with an opening that leads from the water receiving portion 41 to the rotor immersion portion 42 below the lower left side plate 22 and the like. Accordingly, the opening is closed with water in a state where water is in the water tray 40, and the air is not allowed to escape from the water receiving portion 41 to the rotor immersion portion 42 through the opening.

  The partition plate 45 extends upward from above the partition wall 43 without a gap. In a state where the water tray 40 is mounted, the partition plate 45 is fitted to the fan casing 70 without a gap. Then, the water tray 40 is locked to the fan casing 70 in the state shown in FIG. When locked, the partition plate 46 is also superimposed on the fan casing 70 and closes the gap between the water tray 40 and the fan casing 70. An elastic pad 91 is attached above the partition plate 45. When the water tank 30 is mounted, the pad 91 is pushed by the water tank 30. The seal member 92 (see FIG. 11) is provided at the portion where the partition plate 45 and the fan casing 70 overlap, as in the case where the partition plate 45 and the filter member 80 are overlapped.

  A space Sp <b> 2 in which the humidification rotor 50 is accommodated is a space inside the housing formed by the fan casing 70 and the filter support member 80. The space Sp <b> 2 is surrounded by the side wall 71, the upper wall 72, the lower wall 73, the rear wall 74, the partition plates 45 and 46, and the filter support member 80. Thereby, the space Sp2 is partitioned from the external space Sp1, and the path connecting the external space Sp1 and the space Sp2 is limited to a specific path such as the suction port 11 or the air outlet 12. This housing has no openings other than the honeycomb-shaped openings formed in the filter support member 80 and the openings provided in the rear wall 74. Therefore, the same amount of air as the air supplied from the filter support member 80 to the space Sp <b> 2 passes through the rear wall 74 from the space Sp <b> 2 and is supplied to the sirocco fan 16.

  As can be seen from FIGS. 1, 2, 6, and the like, the main body casing 20 is narrowed in a bowl shape at the lower part. For example, the lower wall 73 is curved inward from the side wall 71. The bottom 77 of the main body casing 20 connected to the stand 25 in order to enlarge the bottom of the air cleaner 10 is narrower than the stand 25.

  FIG. 7 is a perspective view of the water tray. FIG. 8 is a diagram showing a configuration of a part in which a water receiving portion 41, a rotor immersion portion 42, a partition wall 43, and a partition plate 46 of a water tray are integrally formed. FIG. 8A is a plan view of this component, FIG. 8B is a front view of this component, and FIG. 8C is a side view showing only a partition wall portion.

  As shown in FIG. 7, the water receiving unit 41 is provided with a float 60 for detecting the water level. A magnet is attached to the float 60, and a reed switch is attached to the fan casing 70. The distance from the magnet to the reed switch changes depending on the vertical movement of the float 60. When the water level stored in the water receiving unit 41 is high and the float 60 is raised, the distance between the magnet and the reed switch is shortened, so the reed switch senses the magnet and turns on. On the other hand, when the water level becomes low, the magnet moves down together with the float 60, so the distance between the magnet and the reed switch becomes longer, so the reed switch stops sensing the magnet and turns off.

  As shown in FIG. 8A, screws for fastening the partition plate 45 are screwed into the two screw holes 40 a in the vicinity of the water receiving portion 41 and the partition wall 43. In addition, screws for fastening the bearings 44 are screwed into the screw holes 40b and 40c provided in the front side wall 42a and the rear side wall 42b of the rotor immersion part 42, respectively.

  As can be seen from FIG. 8B, the partition plate 46 projects below the water tray 40. The partition plate 46 extends in the front-rear direction below the water tray 40. Further, the partition plate 46 extends to the front side and the back side of the water tray 40. The partition plate 46 hits the lower wall 73 of the housing below the water tray 40, hits the filter support member 80 on the front side, and hits the fan casing 70 on the back side, thereby partitioning the housing space Sp2 and its external space.

  As shown in FIG. 8C, the partition wall 43 is provided with an opening 43a, and the water receiving part 41 and the rotor immersion part 42 are connected by the opening 43a. Therefore, the water supplied from the water tank 30 to the water receiving part 41 flows into the rotor immersion part 42 through the opening 43a. The water level when water remains in the water tank 30 is indicated by a two-dot chain line 43b. If there is a water level up to this height, the opening 43a is blocked by water, so the opening 43a does not serve as an air bypass path.

  FIG. 9A shows a rear view of the component shown in FIG. 8, and FIG. 9B shows a cross section taken along the line II of FIG. 9A. Moreover, what expanded the periphery of the lower surface side mountain-shaped convex part 40h of the water tray 40 is shown by FIG. On the lower surface 40e, a front rib 40f, a rear rib 40g, a lower surface-side chevron convex portion 40h, a concave portion 40i, and a convex portion 40j are formed. As can be seen from FIGS. 9A and 9B, the height from the lower surface 40e is lower in the rear rib 40g than in the front rib 40f.

  In the lower surface side convex protrusion 40h, the height from the lower surface 40e to the top of the water tray 40 is higher than the height from the lower surface 40e to the rear rib 40g.

  A recess 40i is formed on the opposite side of the rear rib 40g across the lower surface side chevron 40h. A main body side chevron convex portion to be described later is fitted into the concave portion 40i. When the main body side chevron convex portion is fitted in the concave portion 40i, the upper surface of the convex portion 40j having a flat upper surface is in contact with the support surface of the lower wall 73 of the housing described later.

(2-3) Humidification Rotor A humidification rotor 50 shown in FIG. 6 has a structure in which a disk-shaped porous vaporization filter 51 is attached to a ring-shaped frame 52. The humidification rotor 50 performs humidification by vaporizing water from the vaporization filter 51. Therefore, it is designed so that the lower part of the dry vaporization filter 51 is immersed in the water of the rotor immersion part 42 as the humidification rotor 50 rotates. Further, in order to assist the water supply to the vaporization filter 51, water is pumped up from the rotor immersion part 42 by the water reservoir 53. Water is supplied from the water reservoir 53 through the hole (not shown) of the ring frame 52 following the inner periphery of the ring frame 52 to the vaporization filter 51 on the inner periphery of the ring frame 52. Yes. Although not shown, the humidification rotor 50 is rotated by a motor during the humidification operation.

(2-4) Sirocco fan and fan casing FIG. 13 shows a state where the humidification rotor 50 and the bearing 44 are removed from the state shown in FIG. By removing the humidification rotor 50, the sirocco fan 16 on the downstream side of the humidification rotor 50 can be seen. Humidified air is supplied to the sirocco fan 16 from the opening 76 of the rear wall 74 of the housing.

(2-5) Support surface of housing and support surface side protrusion FIG. 11 is a perspective view showing the structure of the fan casing. The lower wall 73 of the housing is a part of the fan casing 70. A flat portion of the lower wall 73 is a support surface 75 that supports the water tray 40. The support surface 75 is provided at a position higher than the stand 25. The front rib 40f of the water tray 40 slides on the support surface 75. The water tray 40 is separated from the stand 25, and the lower surface side mountain-shaped convex portion 40 h that is the locked portion of the water tray 40 is not rubbed against the upper surface of the stand 25.

  In addition, the support surface 75 is provided with a support surface side chevron convex portion 75a and an internal convex portion 75b. The rear rib 40g of the water tray 40 slides on the support surface side convex portion 75a and the internal convex portion 75b. And the water tray 40 is locked by the support surface side chevron convex part 75a and the lower surface side chevron convex part 40h. As described above, the support surface side chevron 75a constituting the lock portion on the main body side is provided inside the housing for forming the space Sp2.

  Both the support surface side chevron convex portion 75a and the inner convex portion 75b have a width wider than the rear rib 40g. That is, it has a long shape in a direction (y-axis direction) perpendicular to the insertion direction (x-axis direction). The cross section perpendicular to the y-axis direction (cross section cut along the xz plane) has a substantially triangular shape.

(3) Mounting and Locking of Water Tray (3-1) Mounting of Water Tray To facilitate the description of mounting of the water tray 40, the humidifying rotor 50 and the bearing 44 mounted together with the water tray 40 are removed, and the main body casing 20 And FIG. 11 to FIG. 13 showing a state where the filter support member 80 and the like are removed. FIG. 14 shows a cross section cut along the xz plane in the state of FIG. FIG. 15 shows an enlarged part of a cross section cut along the yz plane in a state where the filter support member 80 is attached. FIG. 16 shows a cross section taken along the xz plane in the state of FIG.

  The state shown in FIG. 11 corresponds to the state in which the water tray 40 is removed. The water tray 40 is inserted along the x-axis direction from the right side in FIG.

  As shown in FIGS. 14 and 15, the front rib 40f slides on the support surface 75 of the fan casing 70, and the rear rib 40g slides on the support surface side chevron 75a. In order to facilitate insertion of the rotor immersion portion 42 of the water tray 40, gaps 95, 96, and 97 are provided between the rotor immersion portion 42 and the fan casing 70 and the filter support member 80. The gaps 95, 96, and 97 are closed by the partition plate 46 when the mounting is completed.

  As shown in FIG. 16, in the state where the mounting is completed, the water tray 40 cannot be easily removed by the lower surface side chevron convex portion 40h hitting the support surface side chevron convex portion 75a. As shown in FIG. 16, at this time, the support surface side chevron 75a and the lower surface chevron 40h are closer to the space Sp2 in which the humidification rotor 50 is accommodated than the partition plates 45 and 46 and the partition wall 43. Has been placed. At this time, the rear rib 40g is also supported by the inner convex portion 75b. Therefore, it becomes difficult to cause rotation around the x-axis on the front end side of the water tray 40, and stability is increased.

(3-2) Water Tray Lock FIG. 17 shows an enlarged cross section around the support surface-side chevron 75a and the lower-surface chevron 40h in a state where the mounting has been completed. In the cross section shown in FIG. 17, the support surface-side chevron 75a is fitted in the recess 40i, and the top of the support-surface chevron 75a is not in contact with the lower surface 40e. Further, the rear rib 40 g side is supported by the convex portion 40 j having a flat convex surface contacting the support surface 75.

  As shown in FIG. 17, the outer slope 40hn of the lower surface side convex portion 40h is steeper than the inner inclined surface 40hm of the lower surface side convex portion 40h. Further, in the support surface side chevron convex portion 75a, the inner slope 75am is steeper than the outer slope 75an.

  The lower-side chevron 40h having such a shape protrudes toward the support surface from the rear rib 40g. The lower surface side chevron convex portion 40h protrudes more to the support surface side than the sliding region in which the top of the support surface side chevron convex portion 75a and the rear rib 40g slide. By having such a support surface side chevron convex portion 75a and a lower surface side chevron convex portion 40h, the force required until the lower surface side chevron convex portion 40h contacts the support surface side chevron convex portion 75a when the water tray 40 is mounted. The water tray 40 is not pushed unless pushed with a stronger force. However, since both the inner slope 40hm of the lower face side convex part 40h and the outer slope 75an of the support face side convex part 75a have a relatively gentle slope, the lower face side convex part only by pushing the water tray 40. 40h climbs the support surface side chevron 75a. That is, the lower surface 40e of the water tray 40 is pushed by the support surface 75 and lifted by the operation of pushing the water tray 40.

  As already described, when the mounting is completed, the support surface side chevron convex portion 75a is fitted into the concave portion 40i of the lower surface 40e, so that the lower surface side chevron convex portion 40h is pushed up by the support surface side chevron convex portion 75a. As a result, the raised water tray 40 is lowered. In this state, the steep inner slope 75am of the support-side chevron 75a is in contact with the steep outer slope 40hn of the lower-side chevron 40h, so that the water tray 40 is lifted and pulled out. Operation is required. In this way, the water tray 40 is structured so that it cannot be easily removed.

  Further, in the state where the mounting is completed as described above, the water tray 40 is more strongly locked to the fan casing 70 as the seal member 90 shown in FIG. 5 and the seal member 92 shown in FIG. 11 are deformed. Furthermore, when the water tank 30 is placed on the water tray 40, it is difficult to unlock the water tray 40 and the fan casing 70 due to the weight of the water tank 30. At this time, when the water tank 30 pushes the pad 91 of the partition plate 45, a force is applied in a direction in which the partition plate 45 pushes the seal members 90 and 92, and a gap is hardly generated.

The support surface 75 of the fan casing 70 (main body) has a support surface side convex protrusion 75a (lock portion). The support surface 75 forms a part of the lower wall 73 of the housing for housing the humidification rotor 50 (humidification element). A space Sp2 (internal space) including the periphery of the humidification rotor 50 is partitioned from the external space Sp1 by the water tray 40, the fan casing 70, and the filter support member 80. Here, the external space Sp <b> 1 is a space including not only the inside formed between the main body casing 20 and the partition plate 45 but also the outside of the main body casing 20. And when the lower surface side mountain-shaped convex part 40h (locked part) of the water tray 40 is mounted | worn with the fan casing 70, it locks to the support surface side mountain-shaped convex part 75a in the place which does not face external space Sp1. For this reason, when the water tray 40 is mounted, not only the support surface side chevron convex portion 75a and the lower surface side chevron convex portion 40h can be seen, but also the design surface such as the stand 25 positioned in the external space Sp1 when the water tray 40 is mounted. Further, there is no risk of scratching by the lower surface side convex portion 40h. Thereby, even if it is a case where the water tray 40 must be mounted | worn from a side for a humidification function, the air cleaner 10 excellent in the designability can be provided.

  In particular, when the lower part of the main body casing 20 is formed in a bowl shape, the stand 25 is provided on the bottom 77, and stability is achieved. Since the support surface side chevron convex portion 75a (lock portion) is not provided on the stand 25, the design of the stand 25 is not impaired. At the same time, since the upper surface of the stand 25 is not damaged by the lower surface side convex portion 40h, a beautiful design is maintained.

(4-2)
The lower surface side chevron 40h (locked part) of the water tray 40 is locked to the support surface side chevron 75a (lock part) on the humidification rotor 50 (humidification element) side of the partition plates 45 and 46. . As a result, the water tray 40 is pushed toward the humidification rotor 50 by the support-surface-side chevron 75a, and the partition plate 45 is placed on the fan casing 70 and the seal members 90 and 92 of the filter support member 80 that form the housing. Or the partition plate 46 is pressed against the fan casing 70. Thereby, generation | occurrence | production of the clearance gap which leads from the external space Sp1 to the internal space Sp2 is prevented, and the fall of a humidification function or an air purification function is prevented.

(4-3)
The lower surface side convex portion 40h of the water tray 40 is configured to abut against the support surface side convex portion 75a when mounted. In a state where the lower surface side chevron convex portion 40h hits the support surface side chevron convex portion 75a, the inner inclined surface 40hm of the lower surface side chevron convex portion 40h rides on the outer slope 75an of the support surface side chevron convex portion 75a shown in FIG. Therefore, unless the top of the support surface side chevron convex portion 75a is pushed in with a force stronger than the force when the rear rib 40g is slid, it is not possible to shift to the mounting completion state as shown in FIG. For this reason, the user perceives the lower surface side convex portion 40h, which conveys the start of the lock, as it rides on the support surface side convex portion 75a, and operates toward the completion of the mounting of the water tray 40. I can recognize that. This makes it easy to mount the water tray 40 even if the locking mechanism is not visible.

  Further, the structure in which the lower surface side convex portion 40h protrudes from the rear rib 40g and the structure of the support surface side convex portion 75a for sliding the rear rib 40g are formed in a water tray by plastic injection molding or the like. 40 and the fan casing 70 can be formed at the same time, so that it can be formed at low cost.

(4-4)
In the fan casing 70 and the filter support member 80 (main body), seal members 90 and 92 are formed at portions where the partition plate 45 of the water tray 40 overlaps. Moreover, the support surface side chevron convex portion 75a is formed as a simple protruding portion, and there is no need to provide an opening in the surrounding fan casing 70. Therefore, it is possible to prevent the generation of an air path that leads from the internal space Sp2 to the external space Sp1. Thereby, the fall of a humidification function and the fall of an air purifying function can be prevented.

(5) Modification (5-1) Modification 1A
In the above embodiment, the vaporization humidification method using the humidification rotor 50 as the humidification element is taken as an example. However, other humidification methods such as the heater humidification method and the ultrasonic humidification method are not used for the humidification element. Can be used.
