Description

Wall-mounted air conditioner indoor unit

[0001] It relates to an air conditioner indoor unit.

[0002] Conventionally, as a method of fixing a drain hose to a wall-mounted air conditioner indoor unit, a method of connecting the drain hose and the drain pan and screwing a fixing member for fixing the drain hose to the drain pan has been adopted. For example, in Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2011-149616), the drain hose is fixed to the air conditioner indoor unit by screwing the fixing member from the back side to the front side of the wall-mounted air conditioner indoor unit.

[0003] During maintenance, when removing the drain hose from the air conditioner indoor unit, if the member for fixing the drain hose to the wall-mounted air conditioner indoor unit is screwed from the back side of the air conditioner indoor unit, the maintainability deteriorates.

[0004] The wall-mounted air conditioner indoor unit according to the first aspect includes a drain pan, a drain hose, a first member, and a second member. The drain pan has an outlet and receives condensed water. The end of the drain hose is connected to the outlet of the drain pan. The first member is fixed to the drain pan. The second member is fixed to the drain hose. The first member and the second member are fastened by a fastening member that allows fastening work from the front side or the lower side.

[0005] According to this configuration, since the fastening work of the first member and the second member can be performed from the front side or the lower side, the maintainability is improved.

[0006] The wall-mounted air conditioner indoor unit according to the second aspect is the wall-mounted air conditioner indoor unit according to the first aspect, and the fastening member is a screw.

[0007] The wall-mounted air conditioner indoor unit according to the third aspect is the wall-mounted air conditioner indoor unit according to the first aspect or the second aspect, and further includes a casing disposed on the front side of the drain pan. The wall-mounted air conditioner indoor unit allows the fastening work to be performed with the casing removed.

[0008] According to this configuration, since the fastening work can be performed with the casing removed, the maintainability is improved.

[0009] The wall-mounted indoor air conditioning unit according to the fourth perspective is a wall-mounted indoor air conditioning unit according to any of the first, second, or third perspectives, wherein the first and second components are made of metal.

[0010] The wall-mounted indoor air conditioning unit according to the fifth perspective is a wall-mounted indoor air conditioning unit according to any of the first, fourth, or fourth perspectives, further comprising an insulating member that covers the outer surface of the outlet of the drain pan. The first and second members are arranged so that fastening work can be performed in the space outside the insulating member.

[0011] With this configuration, the first and second members are arranged so that fastening work can be performed in the space outside the insulating member, thus suppressing a decrease in maintainability.

[0012] The wall-mounted indoor air conditioning unit according to the sixth viewpoint is a wall-mounted indoor air conditioning unit according to any of the first to fifth viewpoints, wherein the first member has a plate-shaped first plate-like portion. The second member has a plate-shaped second plate-like portion. The first plate-like portion and the second plate-like portion overlap in at least a portion. The overlapping portion of the first plate-like portion and the second plate-like portion is fastened together by a fastening member.

[0013] This configuration allows for fastening of the first and second components from the front or bottom, thereby improving maintainability.

[0014] A wall-mounted indoor air conditioning unit according to the seventh aspect is a wall-mounted indoor air conditioning unit according to the sixth aspect, wherein the first member further has a first adjacent portion adjacent to the first plate-like portion. The second member further has a second adjacent portion adjacent to the second plate-like portion. The first plate-like portion is inclined with respect to the first adjacent portion, and / or the second plate-like portion is inclined with respect to the second adjacent portion.

[0015] This configuration allows fastening members to be tightened from a direction aligned with the horizontal, thus improving maintainability.

[0016] The wall-mounted indoor air conditioning unit according to the eighth viewpoint is a wall-mounted indoor air conditioning unit according to any of the first to seventh viewpoints, and the drain pan further comprises a main body. The fastening members are arranged in the space below the main body.

[0017] With this configuration, the first and second members are fastened at the lower part of the drain pan body, thus saving space in the left-right direction within the three-dimensional space of the casing.

[0018] The wall-mounted indoor air conditioning unit according to the ninth viewpoint is a wall-mounted indoor air conditioning unit according to the sixth or seventh viewpoint, wherein the second member further has a C-shaped fitting portion. The fitting portion is loosely fitted onto the drain hose.

[0019] This configuration facilitates the fastening of the first and second components, improving maintainability.

[0021] (1) Overall Configuration Figure 1A shows a perspective view of the exterior of the indoor air conditioning unit 1. Figure 1B shows a schematic perspective view of the inside of the casing 100 of the indoor air conditioning unit 1. Note that in Figure 1B, the indoor heat exchanger 20 and fan 25 are not shown. The wall-mounted indoor air conditioning unit 1 (hereinafter referred to as the indoor air conditioning unit 1) performs air conditioning operations such as cooling, heating, dehumidification, and ventilation in the space (target space SP) in which the indoor air conditioning unit 1 is installed. The indoor air conditioning unit 1 is attached to the wall surface of the target space SP via an indoor unit holder. The indoor air conditioning unit 1 mainly comprises a casing 100, an indoor heat exchanger 20, a fan 25, a drain pan 30, a drain hose 40, a first member 50, a second member 60, an insulating member 70, and electrical components 122.

[0022] In the following embodiments, expressions such as up, down, left, right, front, and back may be used to describe directions and positional relationships, but the directions indicated by these expressions follow the directions indicated by the arrows in the drawings.

[0023] The casing 100 forms a roughly rectangular three-dimensional space with a front panel 101, an upper panel 102, a lower panel 103, and side panels 104. The indoor heat exchanger 20, fan 25, drain pan 30, drain hose 40, first member 50, second member 60, insulation member 70, and electrical components 122 are housed within the three-dimensional space of the casing 100. The front panel 101 is positioned on the front side of the drain pan 30, and its upper end is rotatably supported by a hinge. The upper panel 102 is provided with an intake port consisting of multiple slits. An air outlet is provided from the lower part of the front panel 101 to the front of the lower panel 103. The front panel 101, upper panel 102, lower panel 103, and side panels 104 can be removed while the indoor air conditioning unit 1 is installed. By removing the front panel 101, top panel 102, bottom panel 103, and side panel 104, it becomes possible to access the components of the air conditioning indoor unit 1, such as the first member 50, the second member 60, the fastening member 5, and the electrical components 122.

[0024] As shown in Figure 1C, the indoor heat exchanger 20 is located inside the casing 100. A refrigerant flows inside the indoor heat exchanger 20. The refrigerant flowing through the indoor heat exchanger 20 exchanges heat with the indoor air drawn into the casing 100 by the fan 25.

[0025] As shown in Figure 1C, the fan 25 is located below the indoor heat exchanger 20. The fan 25 is connected to a fan motor and rotates when the fan motor is driven. When the fan 25 rotates, indoor air is drawn into the casing 100 through the intake port on the top plate 102. The indoor air drawn into the casing 100 passes through the indoor heat exchanger 20 and the fan 25, and is blown out of the casing 100 through an outlet located from the bottom of the front plate 101 to the front of the bottom plate 103.

[0026] (2) Detailed Configuration (2-1) Drain Pan 30 As shown in Figure 1C, the drain pan 30 is composed of a first drain pan 30a and a second drain pan 30b. The first drain pan 30a is located on the front side of the air conditioning indoor unit 1, and the second drain pan 30b is located on the rear side. As shown in Figures 2A and 2B, the first drain pan 30a includes a main body 35 that receives condensation water generated in the indoor heat exchanger 20, and an outlet 31 that is connected to a first end 41a, which will be described later. The second drain pan 30b is part of a structural member 111 that constitutes part of the casing 100. The water condensed on the indoor heat exchanger 20 falls into the main body 35 of the first drain pan 30a and into the second drain pan 30b. The condensation water accumulated in the second drain pan 30b flows into the main body 35. The condensation water accumulated in the main body 35 flows into the outlet 31. The condensed water that flows into the outlet 31 flows to the first end 41a, which will be described later. The condensed water that flows into the first end 41a flows to the second end 41b, which will be described later. The first member 50, which will be described later, is fixed to the main body 35.

[0027] As shown in Figure 2B, the outer surface of the outlet portion 31 is covered with an insulating material 70 made of foamed polyethylene. By covering the outer surface of the outlet portion 31 with the insulating material 70, condensation on the outlet portion 31 is suppressed.

[0028] (2-2) Drain hose 40 As shown in Figure 5, the drain hose 40 has a two-layer structure in which the outer circumference of a resin tube 45 is covered with an insulating tube 46. The resin tube 45 is a pipe made of synthetic resin or the like. The resin tube 45 is bellows-shaped. Therefore, the drain hose 40 is expandable and contractible in the direction of expansion and contraction of the bellows. The end 41 of the drain hose includes a first end 41a and a second end 41b. A second member 60, which will be described later, is fixed to the first end 41a. The first end 41a is connected to the outlet 31. The second end 41b extends to the outside of the target space SP and communicates with the outdoor space. In this way, the drain hose 40 constitutes a discharge channel for moving the condensed water stored in the drain pan 30 to the outdoors.

[0029] (2-3) First Member 50 and Second Member 60 As shown in Figure 2B, the first member 50 is fixed to the first drain pan 30a. More specifically, the first member 50 is fixed to the main body 35. The first member 50 is a metallic member. As shown in Figure 8, the first member 50 has a plate-shaped first plate-shaped portion 50a. The first member 50 has a first adjacent portion 50b adjacent to the first plate-shaped portion 50a. As shown in Figure 9, the first plate-shaped portion 50a is inclined with respect to the first adjacent portion 50b. As shown in Figures 8 and 10, the first member 50 has a first through hole 501 and a second through hole 502. The first through hole 501 is a hole through which a fixing member 8 that fixes the first member 50 to the main body 35 passes. The second through hole 502 is a hole through which a fastening member 5 that fastens the first member 50 and the second member 60 passes.

[0030] As shown in Figure 2B, the second member 60 is fixed to the drain hose 40. More specifically, the second member 60 is fixed to the first end 41a. The second member 60 is a metallic member. As shown in Figure 11, the second member 60 has a plate-shaped second plate-shaped portion 60a. The second member 60 has a second adjacent portion 60b adjacent to the second plate-shaped portion 60a. As shown in Figure 12, the second plate-shaped portion 60a is inclined with respect to the second adjacent portion 60b. As shown in Figures 11 and 13, the second member 60 has a third through-hole 601. The third through-hole 601 is a hole through which a fastening member 5 that fastens the first member 50 and the second member 60 passes. The second member 60 has a C-shaped fitting portion 60c. The second member 60 is fixed to the drain hose 40 by the fitting portion 60c loosely fitting onto the drain hose 40. Furthermore, "the fitting portion 60c is loosely fitted to the drain hose 40" means that the fitting portion 60c of the second member 60 is fixed to the drain hose 40 so that it cannot move in the direction of expansion and contraction of the drain hose 40, but can rotate circumferentially in the direction of rotation of the drain hose 40.

[0031] The first plate-shaped portion 50a and the second plate-shaped portion 60a overlap in at least a portion. The overlapping portion of the first plate-shaped portion 50a and the second plate-shaped portion 60a is fastened by a fastening member 5 that can be fastened from the front or the bottom. Here, the fastening member 5 is a screw. The fastening member 5 fastens the overlapping portion of the first plate-shaped portion 50a and the second plate-shaped portion 60a by passing through the second through hole 502 and the third through hole 601. By fastening the overlapping portion of the first plate-shaped portion 50a and the second plate-shaped portion 60a, the outlet portion 31 of the first drain pan 30a and the first end portion 41a of the drain hose 40 are connected.

[0032] As shown in Figures 2B and 3, the first member 50 and the second member 60 are positioned on the drain pan 30 and the drain hose 40 so that fastening can be performed in the space outside the heat insulating member 70.

[0033] In this example, the first plate-like portion 50a is inclined with respect to the first adjacent portion 50b, and the second plate-like portion 60a is inclined with respect to the second adjacent portion 60b. However, it is not necessary for the first plate-like portion 50a and the second plate-like portion 60a to be inclined with respect to the first adjacent portion 50b and the second adjacent portion 60b (as will be explained later).

[0034] (2-4) Electrical components 122 Although not shown in the illustration, the electrical components 122 are located on the front side of the first member 50 and the second member 60. The electrical components 122 include an operation switch, a display unit, an electromagnetic wave receiver, and a buzzer. The user can operate the operation / stop of the air conditioning indoor unit 1 by pressing the operation switch. The display unit indicates the operating status of the air conditioning indoor unit 1, the timer status, the need to clean the filter, the occurrence of an abnormality, etc., by lighting up, flashing, etc. The electromagnetic wave receiver receives electromagnetic waves from the remote controller. The electromagnetic waves are infrared rays. The buzzer is not exposed to the outside of the casing 100, but it is part of the electrical components 122. When the radio wave receiver receives a signal from the remote controller, the buzzer emits a sound corresponding to that signal. As shown in Figure 14, the electrical components 122 are attached to the second support unit 124. The second support unit 124 is movably attached to the first support unit 123.

[0035] When the indoor unit 1 of the air conditioner is in use, the second support part 124 is located in the path used to remove the first drain pan 30a from the casing 100. By moving the second support part 124 to the position shown in Figure 15, the second support part 124 is moved out of the removal path for the first drain pan 30a.

[0036] (3) Removal of the first drain pan 30a When performing maintenance on the indoor unit 1 of the air conditioner, it is preferable to remove the first drain pan 30a from the casing 100. The procedure for removing the first drain pan 30a will be described below.

[0037] (3-1) Moving the electrical component 122 and the second support part 124 As described above, the electrical component 122 is attached to the second support part 124. Also as described above, the second support part 124 is located on the front side of the first member 50 and the second member 60. For this reason, we first move the second support part 124. As can be seen from Figure 14, the second support part 124 has a hinge structure and is attached to the first support part 123. The second support part 124 can rotate around the support column 124a of the hinge part. By moving the second support part 124, the second support part 124 is outside the removal path of the first drain pan 30a, and the first member 50 and the second member 60 are exposed.

[0038] (3-2) Removal of the drain hose 40 In order to remove the first drain pan 30a from the casing 100, it is necessary to remove the drain hose 40 from the first drain pan 30a. As described above, the drain hose 40 is connected to the first drain pan 30a by the first end 41a being connected to the outlet 31 by the first member 50 and the second member 60.

[0039] By moving the second support portion 124, to which the electrical component 122 is attached, to the position shown in Figure 15, the first member 50 and the second member 60 are exposed. This makes it easier to fasten the fastening member 5 from the front or bottom side of the first member 50 and the second member 60, and also makes it easier to remove the fastening member 5. In this way, the drain hose 40 is removed from the first drain pan 30a.

[0040] (3-3) Removal of the first drain pan 30a As described in (3-1) and (3-2), the first drain pan 30a can be removed by moving the second support part 124 outside the removal path for the first drain pan 30a and removing the fastening member 5. The first drain pan 30a can be removed from the casing 100 by pulling it out in the forward and downward direction. The second member 60 remains fixed to the drain hose 40, and the first drain pan 30a can be removed from the casing 100.

[0041] (4) Features (4-1) Wall-mounted indoor air conditioning units require periodic maintenance, and it is preferable to remove the drain pan from the casing during maintenance. It is also preferable to remove the drain hose from the drain pan during maintenance. In such cases, if the fastening members that secure the drain hose and drain pan to the wall-mounted indoor air conditioning unit are fastened from the back to the front of the wall-mounted indoor air conditioning unit, maintainability will be reduced.

[0042] In this disclosure, a first member 50 fixed to the first drain pan 30a and a second member 60 fixed to the drain hose 40 are fastened together by a fastening member 5. The first member 50 and the second member 60 are fastened together by a fastening member 5 that can be fastened from the front or the bottom. This makes it possible to attach and detach the drain hose 40 from the front or the bottom of the air conditioning indoor unit 1, and makes it easy to remove the first drain pan 30a from the casing 100. In this way, the maintainability of the air conditioning indoor unit 1 in this disclosure is improved.

[0043] Alternatively, during maintenance, it may be necessary to remove the drain hose to check for blockages or leaks. In such cases, the air conditioning indoor unit 1 in this disclosure allows for the attachment and detachment of the drain hose 40 from the front or bottom of the indoor unit 1, thus improving maintainability.

[0044] (4-2) The air-conditioning indoor unit 1 in the present disclosure includes a casing 100. In the air-conditioning indoor unit 1 in the present disclosure, a fastening member 5 is disposed at a position where fastening work can be performed by removing the front panel 101, the upper panel 102, the lower panel 103, and the side panel 104 of the casing 100. Thus, by facilitating access to the fastening member 5, the air-conditioning indoor unit 1 has improved maintainability.

[0045] (4-3) The condensed water flowing through the outlet portion 31 is at a low temperature. Therefore, if heat insulation is not ensured on the outer surface of the outlet portion 31, the outer surface of the outlet portion 31 may be dew-covered. Further, when the first member 50 is directly fastened to the outlet portion 31, the first member 50 may be dew-covered.

[0046] As shown in FIG. 2B, the air-conditioning indoor unit 1 in the present disclosure includes a heat-insulating member 70. The heat-insulating member 70 covers the outer surface of the outlet portion 31. Thereby, heat insulation of the outer surface of the outlet portion 31 is ensured.

[0047] As shown in FIG. 2A, the first member 50 is fixed to the main body portion 35 so as not to be in direct contact with the outlet portion 31. Thereby, heat insulation of the first member 50 is ensured.

[0048] As shown in FIGS. 3 and 15, the first member 50 and the second member 60 in the present disclosure are arranged so that fastening work can be performed in the outer space of the heat-insulating member 70. Thereby, since the fastening work can be performed without going through steps such as the removal work of the heat-insulating member 70, a decrease in maintainability can be suppressed.

[0049] With the above configuration, in the air-conditioning indoor unit 1 in the present disclosure, heat insulation of the outer surface of the outlet portion 31 and the first member 50 is ensured, and a decrease in maintainability can be suppressed.

[0050] (4-4) The drain hose 40 is connected to the first drain pan 30a so as to extend downward and rearward when viewed from the front of the indoor unit 1 of the air conditioner, in order to drain condensed water to the outside of the target space SP. The first member 50 and the second member 60 are fixed to the main body 35 and the first end 41a so as to follow the drain hose 40 which extends downward and rearward. For this reason, if the first plate-shaped part 50a and the second plate-shaped part 60a are not inclined with respect to the first adjacent part 50b and the second adjacent part 60b (i.e., the first plate-shaped part 50a and the second plate-shaped part 60a are on the same plane as the first adjacent part 50b and the second adjacent part 60b), when fastening the first member 50 and the second member 60 with the fastening member 5 it becomes necessary to tighten the fastening member 5 from the front and upper direction, which reduces maintainability.

[0051] As shown in Figures 9 and 12, the first plate-shaped portion 50a and the second plate-shaped portion 60a in this disclosure are inclined with respect to the first adjacent portion 50b and the second adjacent portion 60b. More specifically, the first plate-shaped portion 50a and the second plate-shaped portion 60a are inclined such that when fastened by the fastening member 5, the tightening direction of the fastening member 5 is aligned with the horizontal direction (perpendicular to the floor surface of the target space SP). When the first plate-shaped portion 50a and the second plate-shaped portion 60a are inclined in this manner, as shown in Figure 15, the removal direction and tightening direction of the fastening member 5 are aligned with the horizontal direction, making the fastening work of the fastening member 5 easier. As a result, the maintainability of the air conditioning indoor unit 1 is improved.

[0052] (4-5) As shown in Figures 3 and 15, the fastening member 5 in this disclosure is positioned in the space below the first drain pan 30a when viewed from the front side of the indoor air conditioning unit 1. By fastening the first member 50 and the second member 60 in the space below the first drain pan 30a in this way, the indoor air conditioning unit 1 in this disclosure is able to save space in the left-right direction within the three-dimensional space of the casing 100.

[0053] (4-6) As described above, the first member 50 and the second member 60 are fastened together by the fastening member 5 passing through the second through hole 502 and the third through hole 601. In this case, if the first member 50 is fixed to the first drain pan 30a and the second member 60 is fixed to the drain hose 40, and the positions of the second through hole 502 and the third through hole 601 do not coincide, it becomes necessary to adjust the positions of the second through hole 502 and the third through hole 601 by methods such as twisting the drain hose 40. If the positions of the second through hole 502 and the third through hole 601 are adjusted by such methods, the reliability of the drain hose 40 may be reduced.

[0054] In this disclosure, the fitting portion 60c is loosely fitted onto the drain hose 40. This allows the second member 60 to rotate in the direction of rotation of the drain hose 40. Therefore, even if the positions of the second through-hole 502 and the third through-hole 601 do not coincide, the positions of the second through-hole 502 and the third through-hole 601 can be easily adjusted by rotating the second member 60. With this configuration, the air conditioning indoor unit 1 in this disclosure improves maintainability while suppressing a decrease in the reliability of the drain hose 40.

[0055] (5) Modified Examples (5-1) Modified Example A In the above embodiment, an example was described in which the first plate-shaped portion 50a is inclined with respect to the first adjacent portion 50b and the second plate-shaped portion 60a is inclined with respect to the second adjacent portion 60b, for the purpose of adjusting the tightening direction of the fastening member 5 to be aligned with the horizontal direction during maintenance. However, the configuration of the first plate-shaped portion 50a and the second plate-shaped portion 60a in this disclosure is not limited to this, and for example, there may be a configuration in which the first plate-shaped portion 50a is inclined with respect to the first adjacent portion 50b and the second plate-shaped portion 60a is not inclined with respect to the second adjacent portion 60b, or a configuration in which the first plate-shaped portion 50a is not inclined with respect to the first adjacent portion 50b and the second plate-shaped portion 60a is inclined with respect to the second adjacent portion 60b.

[0056] In the former case, the second member 60 is fixed to the drain hose 40 at an angle perpendicular to the floor surface of the target space SP, so that the tightening direction of the fastening member 5 is aligned with the horizontal direction. In the latter case, the first member 50 is fixed to the first drain pan 30a at an angle perpendicular to the floor surface of the target space SP, so that the tightening direction of the fastening member 5 is aligned with the horizontal direction.

[0057] Thus, even if neither the first member 50 nor the second member 60 is tilted, maintainability can be improved by adjusting the angle at which the first member 50 or the second member 60 is fixed.

[0058] While embodiments of this disclosure have been described above, it should be understood that various modifications to the form and details are possible without departing from the spirit and scope of this disclosure as described in the claims.
