DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an example of a preferred embodiment of the present invention will be described. However, the following embodiment is merely an example, and the present invention is not limited to the following embodiment.

[0009] (First embodiment) Fig. 1 is a schematic perspective view of the air conditioner 1 according to the first embodiment. Fig. 2 is a schematic cross-sectional view of the air conditioner 1 according to the first embodiment. Fig. 3 is a schematic rear view of the air conditioner 1 according to the first embodiment.

[0010] The air conditioner 1 shown in Figures 1 to 3 has at least one of a plurality of functions, such as a function to adjust the temperature in the room, a function to adjust the humidity in the room, a function to purify the air in the room, a function to supply ions to the room, etc. The air conditioner 1 is sometimes called, for example, an air conditioner.

[0011] The air conditioner 1 includes an indoor unit 100 and an outdoor unit (not shown). The indoor unit 100 is installed indoors. The outdoor unit is installed outdoors. The indoor unit 100 and the outdoor unit are connected by a refrigerant circuit (not shown). In each of the indoor unit 100 and the outdoor unit, heat is exchanged between the refrigerant flowing through the refrigerant circuit and the air, so that, for example, heated or cooled air is generated in the indoor unit 100 and supplied to the room.

[0012] (indoor unit 100) Next, the indoor unit 100 will be described mainly with reference to FIG.

[0013] 2, the indoor unit 100 includes an indoor unit body 200 and a drain pan 250. The drain pan 250 is disposed in a lower H2 portion of the indoor unit body 200. The drain pan 250 is detachably attached to a lower portion of the indoor unit body 200.

[0014] The indoor unit main body 200 has a housing 201. The housing 201 houses the components of the indoor unit 100.

[0015] Fig. 4 is a schematic perspective view showing a part of the indoor unit 100 in the first embodiment. Fig. 5 and Fig. 6 are schematic cross-sectional views of the housing 201 and the drain pan 250 in the first embodiment, respectively.

[0016] As mainly shown in Fig. 4, the housing 201 has a cabinet 202 and a cover 203. The cover 203 covers at least both sides of the cabinet 202 in the width direction W and a lower side H2 of the cabinet 202. The above-mentioned drain pan 250 is detachably attached to the cabinet 202. The drain pan 250 and the cabinet 202 attached to the drain pan 250 are inserted into the cover 203.

[0017] As shown in FIG. 2, a cabinet 202 of a housing 201 houses a fan 210 and a heat exchanger 220.

[0018] The fan 210 has a function of taking in air into the housing 201 and discharging the air from the housing 201. In detail, an intake port 204 is formed in a portion of the housing 201 located on the upper side H1 of the fan 210. An air filter 230 is attached to this intake port 204. When the fan 210 is driven, indoor air is taken into the housing 201 through this air filter 230. An exhaust port 205 is formed in a portion of the housing 201 located on the front side D1, which is one side of the fan 210 in the depth direction D. When the fan 210 is driven, the air inside the housing 201 is discharged outside the housing 201 through the exhaust port 205.

[0019] A front panel 240 is attached to the housing 201. The front panel 240 is configured to be able to open and close the discharge port 205. Specifically, the front panel 240 is moved from a state in which the discharge port 205 is closed as shown in FIG. 2 to an open state in which the discharge port 205 is opened by rotating an upper side H1 portion of the front panel 240 about a lower side H2 portion of the front panel 240 as an axis. The indoor unit 100 is provided with an actuator (not shown) that drives the front panel 240. The front panel 240 is driven by this actuator to open and close the discharge port 205. The front panel 240 also has a function of controlling the direction of air discharged from the discharge port 205.

[0020] The heat exchanger 220 is disposed within the housing 201. The heat exchanger 220 is located on one side of the fan 210 in the depth direction D, specifically, on the front side D1. The heat exchanger 220 covers the entire front side D1 of the fan 210. The heat exchanger 220 extends from a lower side H2 below an end of the lower side H2 of the fan 210 to an upper side H1 above an end of the upper side H1 of the fan 210. In a side view, the heat exchanger 220 extends obliquely from the rear side D2 to the front side D1 as it moves from the lower side H2 to the upper side H1.

[0021] The heat exchanger 220 is disposed between the fan 210 and the outlet 205. The air flowing from the fan 210 toward the outlet 205 passes through the heat exchanger 220 and is then discharged from the outlet 205.

[0022] The heat exchanger 220 is connected to a refrigerant circuit (not shown). A refrigerant is supplied to the heat exchanger 220 via the refrigerant circuit. In the heat exchanger 220, heat is exchanged between the refrigerant and air, and the cooled or heated air is discharged from the discharge port 205 to the outside of the housing 201.

[0023] A portion of the lower side H2 of the heat exchanger 220 is not covered by the cabinet 202. When viewed from the lower side H2 along the height direction H, the portion of the lower side H2 of the heat exchanger 220 is exposed from the cabinet 202. The portion of the heat exchanger 220 exposed from the cabinet 202 is covered by a drain pan 250. The drain pan 250 has a recess 251 formed therein, which is located on the lower side H2 of the portion of the lower side H2 of the heat exchanger 220. Water generated on the surface of the heat exchanger 220 accumulates in this recess 251.

[0024] In this embodiment, as described above, since the heat exchanger 220 is disposed on the front side D1 of the fan 210, the drain pan 250 is provided so as to reach the front side D1 portion of the housing 201.

[0025] (Mounting plate 300) The indoor unit 100 is attached, for example, to a wall surface inside a room by a mounting plate 300 shown in Fig. 3. Note that the mounting plate 300 is not shown in Fig. 2.

[0026] The mounting plate 300 is a plate-like member fixed to a wall surface inside a room by fastening members such as screws or bolts. The indoor unit 100 is attached to the mounting plate 300 fixed to the wall surface or the like at the front D1, which is one side in the depth direction D. Specifically, of the indoor unit 100, the cabinet 202 and the drain pan 250 are detachably attached to the mounting plate 300. Note that the cabinet does not necessarily need to be detachable from the mounting plate, and the cabinet may be fixed to the mounting plate.

[0027] Fig. 7 is a schematic side view of the drain pan 250 and the mounting plate 300 in the first embodiment. Fig. 8 is a schematic perspective view of the drain pan 250 and the mounting plate 300 in the first embodiment.

[0028] Next, the manner in which the drain pan 250 is attached will be described with reference mainly to FIGS.

[0029] Drain pan 250 is attached to cabinet 202 and mounting plate 300. Specifically, an upper end of a portion of rear side D2 of drain pan 250 is attached to cabinet 202, and a lower end of the portion of rear side D2 of drain pan 250 is attached to mounting plate 300.

[0030] As shown in FIG. 6, a plurality of protrusions 252 are provided at the upper end of the rear side D2 portion of the drain pan 250. The plurality of protrusions 252 are provided at intervals along the width direction W. The plurality of protrusions 252 each protrude toward the front side D2 side in the depth direction D. Meanwhile, a plurality of insertion portions 202a are formed at positions corresponding to the positions of the plurality of protrusions 252 in a portion of the cabinet 202 located on the rear side D2 of the plurality of protrusions 252. The plurality of protrusions 252 are inserted into the corresponding insertion portions 202a, respectively, so that the upper end of the rear side D2 portion of the drain pan 250 is fixed to the cabinet 202. Therefore, the fixed state between the drain pan 250 and the cabinet 202 is released by moving the upper end of the rear side D2 portion of the drain pan 250 to the front side D1.

[0031] In this embodiment, the insertion portion 202a is specifically a through hole. However, in the present invention, the insertion portion is not particularly limited as long as the protrusion can be inserted therein. The insertion portion may be, for example, a recess or the like.

[0032] As shown in Figs. 7 and 8, the mounting plate 300 includes a fixed portion 310 and a plurality of protruding portions 320. The fixed portion 310 is a plate-like portion that is fixed to a wall surface. The plurality of protruding portions 320 each extend from the fixed portion 310 toward a front side D1 that is one side in the depth direction D. Specifically, the plurality of protruding portions 320 each extend from an end of a lower side H2 of the fixed portion 310 toward the front side D1. In this embodiment, the plurality of protruding portions 320 each have a plate shape, and each protruding portion 320 and the fixed portion 310 are substantially perpendicular to each other.

[0033] 8, each of the multiple protrusions 320 includes an engagement portion 321. In this embodiment, the engagement portion 321 is configured as a through hole that penetrates the protrusion 320 in the thickness direction. When the mounting plate 300 is attached to a wall surface that extends along the vertical direction, the through hole that configures the engagement portion 321 extends along the vertical direction.

[0034] A drain pan 250 constituting a part of the indoor unit 100 is provided with a plurality of engaged parts 253. The plurality of engaged parts 253 are provided at positions corresponding to the positions of the corresponding engaging parts 321. The plurality of engaged parts 253 are engaged with the corresponding engaging parts 321. Specifically, in this embodiment, the engaged parts 253 are formed of protrusions extending along the height direction H, and are inserted into through holes constituting the engaging parts 321, so that the engaging parts 321 and the engaged parts 253 are engaged with each other. The plurality of engaged parts 253 are each configured to be displaceable in a direction away from the corresponding engaging parts 321.

[0035] Specifically, the drain pan 250 has a drain pan body 254 and a hook portion 255. The drain pan body 254 is a portion in which a recess 251 is formed and which is located on the lower side H2 of the fan 210 and the heat exchanger 220. The hook portion 255 is attached to the drain pan body 254 so as to be displaceable in both directions in the depth direction D. An engaged portion 253 that protrudes from the hook portion 255 toward the lower side H2 is provided at an end of the rear side D2 of the hook portion 255. For this reason, in this embodiment, the engaged portion 253 is provided so as to be displaceable in both directions in the depth direction D. The engaged portion 253 is displaceable toward the front side D1, which is one side of the depth direction D, from a state in which it is engaged with the engaging portion 321. In other words, the engaged portion 253 is provided so as to be slidable along the depth direction D.

[0036] 5, a through hole 254a extending along the depth direction D is formed in the drain pan body 254. The hook portion 255 is inserted into this through hole 254a. The shape of the through hole 254a is substantially the same as the cross-sectional shape of the hook portion 255, and the hook portion 255 is slidable within the through hole 254a along the depth direction D.

[0037] FIG. 9 is a schematic side view showing a state in which the engaged portion 253 is separated from the engaging portion 321 in the first embodiment.

[0038] As shown in FIG. 9, when the engaged portion 253 slides toward the front side D1 relative to the drain pan body 254, the distance between the end of the rear side D2 of the hook portion 255 on which the engaged portion 253 is provided and the mounting plate 300 becomes longer.

[0039] Incidentally, for example, when performing maintenance on the indoor unit 100, there are cases where it is necessary to remove at least a part of the indoor unit 100, for example, the drain pan 250, from the mounting plate 300. In particular, the drain pan 250 is provided with a recess 251 in which water accumulates, and therefore is one of the members that needs to be removed frequently, for example, for cleaning.

[0040] For example, when removing the drain pan 250 from the mounting plate 300, it is necessary to rotate the drain pan 250 in the rotation direction R around the convex portion 252 provided at the upper end of the end of the rear side D2 of the drain pan 250 as an axis. In the air conditioner 1, the engaged portion 253 is configured to be movable in a direction away from the engaging portion 321. Specifically, the engaged portion 253 is configured to be movable to the front side D1 from a state in which it is engaged with the engaging portion 321. Therefore, even if the drain pan 250 is rotated around the axis A1 extending along the width direction w at the portion where the convex portion 252 is located, the engaged portion 253 is prevented from hitting the mounting plate 300, and the drain pan 250 can be easily rotated. Therefore, the drain pan 250 can be easily removed from the mounting plate 300. Therefore, the maintenance of the indoor unit 100 can be easily performed. Therefore, the air conditioner 1 has excellent maintainability.

[0041] In particular, in the air conditioner 1, because the heat exchanger 220 is disposed on the front side D1 of the fan 210 as shown in Fig. 2, the dimension of the drain pan 250 in the depth direction D tends to be large. As the dimension of the drain pan 250 in the depth direction D increases, it tends to be more difficult to rotate and remove the drain pan 250, so it is particularly effective to configure the engaged portion 253 to be movable, as in this embodiment.

[0042] In the present embodiment, an example in which the engaged portion is provided on the drain pan has been described. However, the present invention is not limited to this configuration. The engaged portion may be provided on any member constituting the indoor unit.

[0043] In this embodiment, an example in which the engaged part is movable to one side in one direction has been described as being movable to the front side D1 along the depth direction D. However, the present invention is not limited to this. The engaged part may be movable, for example, slidable, along a direction away from the engaging part. Specifically, for example, the engaged part may be slidable diagonally upward or downward toward the front side.

[0044] Another preferred embodiment of the present invention will now be described. In the following description, members having substantially the same functions as those in the first embodiment will be denoted by the same reference numerals, and description thereof will be omitted.

[0045] Second embodiment Fig. 10 is a schematic perspective view of the cabinet 202, the drain pan 250, and the mounting plate 300 in the second embodiment. Fig. 11 is a schematic side view of the cabinet 202, the drain pan 250, and the mounting plate 300 in the second embodiment. Fig. 12 is a schematic side view of the cabinet 202, the drain pan 250, and the mounting plate 300 in the second embodiment with the engaged portion separated from the engaging portion.

[0046] In the first embodiment, an example has been described in which the engaged portion 253 can slide from a state in which it is engaged with the engaging portion 321, thereby being able to separate from the engaging portion 321. However, in the present invention, the moving direction of the engaged portion is not particularly limited as long as the engaged portion can move in a direction away from the engaging portion. The engaged portion may be configured to be movable linearly or non-linearly.

[0047] In the second embodiment, an example in which the engaged portion 253 is movable along the rotation direction will be described.

[0048] As shown in Figures 10 and 11, in the second embodiment, the engaged portion 253 is configured to be movable from a state engaged with the engaging portion 321 in a direction away from the engaging portion 321 by rotating about a rotation axis A2 located on the front side D1, which is on one side in one direction from the engaged portion 253.

[0049] Specifically, the hook portion 255 provided with the engaged portion 253 is rotatably attached to the drain pan body 254 at the end of the front side D1 of the hook portion 255. Therefore, the distance between the engaged portion 253 and the engaging portion 321 increases when the engaged portion 253 shown in FIG. 11 rotates about the rotation axis A2 from the state in which the engaged portion 253 is engaged with the engaging portion 321. Therefore, in the second embodiment as well, as in the first embodiment, the drain pan 250 can be easily removed. Therefore, in the second embodiment as well, excellent maintainability of the air conditioner is achieved. [Explanation of symbols]
