DESCRIPTION OF EMBODIMENT

3a

(1) Overall configuration FIG. 1A is a perspective view of the appearance of an air conditioning indoor unit 1. FIG. 1B is a schematic perspective view of the interior of a casing 100 of the air conditioning indoor unit 1. In FIG. 1B, an indoor heat exchanger 20, a fan 25, and the like are not illustrated. The wall-mounted air conditioning indoor unit 1 (hereinafter, air conditioning indoor unit 1) executes an air-conditioning operation such as cooling, heating, dehumidifying, and air blowing in the space where the air conditioning indoor unit 1 is disposed (target space SP). The air conditioning indoor unit 1 is attached to a wall surface of the target space SP via an indoor unit holder. The air conditioning indoor unit 1 mainly includes the casing 100, the indoor heat exchanger 20, the fan 25, a drain pan 30, a drain hose 40, a first member 50, a second member 60, a heat insulating member 70, and an electric component 122 Note that in the following embodiment, in order to describe directions and positional relationship, expressions such as up, down, left, right, front face (front), and back face (rear) are used in some cases. The directions indicated by these expressions follow the directions indicated by arrows in the drawings. The casing 100 forms a substantially rectangular three-dimensional space with a front plate 101, an upper plate 102, a lower plate 103, and a side plate 104. The three-dimensional space of the casing 100 houses the indoor heat exchanger 20, the fan 25, the drain pan 30, the drain hose 40, the first member 50, the second member 60, the heat insulating member 70, and the electric component 122. The front plate 101 is disposed on the front side of the drain pan 30, and an upper end thereof is pivotably supported by a hinge. The upper plate 102 is provided with an intake port including a plurality of slits. A blow-out port is provided from the bottom of the front plate 101 to the front of the lower plate 103. The front plate 101, the upper plate 102, the lower plate 103, and the side plate 104 are removable with the air conditioning indoor unit 1 installed. Removing the front plate 101, the upper plate 102, the lower plate 103, and the side plate 104 allows access to components of the air conditioning indoor unit 1, such as the first member 50, the second member 60, a fastening member 5, and the electric component 122. As shown in FIG. IC, the indoor heat exchanger 20 is disposed 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 indoor air taken into the casing 100 by the fan 25. As shown in FIG. IC, the fan 25 is provided below the indoor heat exchanger 20. The fan 25 is connected to a fan motor and is driven by the fan motor to rotate. When the fan

25 rotates, the indoor air is taken into the casing 100 from the intake port of the upper plate 102. The indoor air taken into the casing 100 passes through the indoor heat exchanger 20 and the fan 25, and is blown out to the outside of the casing 100 from the blow-out port provided from the bottom of the front plate 101 to the front of the lower plate 103. (2) Detailed configuration (2-1) Drain pan 30 As shown in FIG. IC, the drain pan 30 includes 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 back side. The first drain pan 30a includes a body 35 that receives condensation water generated in the indoor heat exchanger 20, and an outlet 31 connected to a first end 41a, which will be described later, as shown in FIGS.2Aand2B. The second drain pan 30b is part of a structural member 111 that constitutes part of the casing 100. The water that has condensed in the indoor heat exchanger 20 falls into the body 35 of the first drain pan 30a and the second drain pan 30b. The condensation water accumulated in the second drain pan 30b flows to the body 35. The condensation water accumulated in the body 35 flows to the outlet 31. The condensation water that has flowed to the outlet 31 flows to the first end 41a, which will be described later. The condensation water that has flowed to the first end 41a flows to a second end 41b, which will be described later. The first member 50, which will be described later, is fixed to the body 35. As shown in FIG. 2B, the outer surface of the outlet 31 is covered with the heat insulating member 70 made of foamed polyethylene. Covering the outer surface of the outlet 31 with the heat insulating member 70 inhibits condensation at the outlet 31. (2-2) Drain hose 40 As shown in FIG. 5, the drain hose 40 has a two-layer structure in which the outer circumference of a resin tube 45 is covered with a heat insulating tube 46. The resin tube 45 is a tube including synthetic resin or the like. The resin tube 45 has a bellows shape. Therefore, the drain hose 40 can expand and contract in the direction of expansion and contraction of the bellows. An end 41 of the drain hose includes the first end 41a and the second end 41b. The second member 60, which will be described later, is fixed to the first end41a. 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 condensation water accumulated in the drain pan 30 to the outdoors. (2-3) First member 50 and second member 60

As shown in FIG. 2B, the first member 50 is fixed to the first drain pan 30a. Inmore detail, the first member 50 is fixed to the body 35. The first member 50 is a metallic member. As shown in FIG. 8, thefirst member 50 includes a plate-shaped first plate-shaped part 50a. The first member 50 includes a first adjacent part 50b adjacent to the first plate-shaped part 50a. As shown in FIG. 9, the first plate-shaped part 50a is inclined with respect to the first adjacent part 50b. As shown in FIGS. 8 and 10, the first member 50 includes 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 body 35 passes. The second through hole 502 is a hole through which the fastening member 5 that fastens the first member 50 and the second member 60 passes. As shown in FIG. 2B, the second member 60 is fixed to the drain hose 40. In more detail, the second member 60 is fixed to the first end 41a. The second member 60 is a metallic member. As shown in FIG. 11, the second member 60 includes a plate-shaped second plate shaped part 60a. The second member 60 includes a second adjacent part 60b adjacent to the second plate-shaped part 60a. As shown in FIG. 12, the second plate-shaped part 60a is inclined with respect to the second adjacent part 60b. As shown in FIGS. 11 and 13, the second member 60 includes a third through hole 601. The third through hole 601 is a hole through which the fastening member 5 that fastens the first member 50 and the second member 60 passes. The second member 60 includes a C-shaped fitting portion 60c. The fitting portion 60c loosely fits with the drain hose 40, whereby the second member 60 is fixed to the drain hose 40. Note that "the fitting portion 60c loosely fits with the drain hose 40" means that the fitting portion 60c of the second member 60 is fixed to the drain hose 40 in an unmovable manner in the expansion and contraction direction of the drain hose 40 and in a manner that allows circulating in the rotation direction of the drain hose 40. The first plate-shaped part 50a and the second plate-shaped part 60a overlap each other at least partially. The part where the first plate-shaped part 50a and the second plate-shaped part 60a overlap each other is fastened by the fastening member 5 that enables the fastening work from the front side or lower side. Here, the fastening member 5 is a screw. The fastening member 5 passes through the second through hole 502 and the third through hole 601, thereby fastening the part where the first plate-shaped part 50a and the second plate-shaped part 60a overlap each other. By fastening the part where the first plate-shaped part 50a and the second plate-shaped part 60a overlap each other, the outlet 31 of the first drain pan 30a and the first end 41a of the drain hose 40 are connected to each other. As shown in FIGS. 2B and 3, the first member 50 and the second member 60 are disposed on the drain pan 30 and the drain hose 40 such that the fastening work is enabled in the outer space of the heat insulating member 70. Note that an example will be described here in which the first plate-shaped part 50a is inclined with respect to the first adjacent part 50b and the second plate-shaped part 60a is inclined with respect to the second adjacent part 60b. However, the first plate-shaped part 50a and the second plate-shaped part 60a do not necessarily have to be inclined with respect to the first adjacent part 50b and the second adjacent part 60b (described later). (2-4) Electric component 122 Although illustration is omitted, the electric component 122 is disposed on the front side of the first member 50 and the second member 60. The electric component 122 includes an operation switch, a display unit, an electromagnetic wave receiver, and a buzzer. The user can manipulate the start and stop of the air conditioning indoor unit 1 by pressing the operation switch. The display unit displays the operating state of the air conditioning indoor unit 1, state of a timer, necessity of cleaning a filter, occurrence of an abnormality, and the like by turning on or blinking light or the like. The electromagnetic wave receiver receives an electromagnetic wave from a remote controller. The electromagnetic wave is infrared rays. The buzzer is not exposed to the outside of the casing 100, but is part of the electric component 122. When the electromagnetic wave receiver receives a signal from the remote controller, the buzzer emits a sound corresponding to the signal. As shown in FIG. 14, the electric component 122 is attached to a second support part 124. The second support part 124 is movably attached to a first support part 123. When the air conditioning indoor unit 1 is used, the second support part 124 is on the route where the first drain pan 30a is removed from the casing 100. By moving the second support part 124 to the position shown in FIG. 15, the second support part 124 is out of the route where the first drain pan 30a is removed. (3) Removal of first drain pan 30a During maintenance of the air conditioning indoor unit 1, the first drain pan 30a is preferably removed from the casing 100. Here, the procedure for removing the first drain pan 30a will be described. (3-1) Movement of electric component 122 and second support part 124 As described above, the electric component 122 is attached to the second support part 124. As described above, the second support part 124 is disposed on the front side of the first member 50 and the second member 60. Therefore, to begin with, the second support part 124 is moved. The second support part 124, as can be seen from FIG. 14, is attached to the first support part 123 by a hinge structure. The second support part 124 can rotate around a support 124a of the hinge part. By moving the second support part 124, the second support part 124 is out of the route where the first drain pan 30a is removed, and the first member 50 and the second member 60 are exposed. (3-2) Removal of 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 first end 41a is connected to the outlet 31 by the first member 50 and the second member 60, whereby the drain hose 40 is connected to the first drain pan 30a. The second support part 124 to which the electric component 122 is attached is moved to the position shown in FIG. 15, whereby the first member 50 and the second member 60 are exposed. This facilitates the fastening work of the fastening member 5 from the front side or lower side of the first member 50 and the second member 60, and facilitates the removal work of the fastening member 5. In this way, the drain hose 40 is removed from the first drain pan 30a. (3-3) Removal of 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 out of the route where the first drain pan 30a is removed, and removing the fastening member 5. The first drain pan 30a can be removed from the casing 100 by pulling out in the front-and-down direction. The first drain pan 30a can be removed from the casing 100 while the second member 60 remains fixed to the drain hose 40. (4) Features (4-1) It is necessary to carry out regular maintenance on the wall-mounted air conditioning indoor unit. The drain pan is preferably removed from the casing during maintenance. During maintenance, the drain hose is preferably removed from the drain pan. In such a case, if the fastening member that fixes the drain hose and the drain pan to the wall-mounted air conditioning indoor unit is fastened from the back side toward the front side of the wall mounted air conditioning indoor unit, the maintainability decreases. In the present disclosure, the first member 50 fixed to the first drain pan 30a and the second member 60 fixed to the drain hose 40 are fastened by the fastening member 5. The first member 50 and the second member 60 are fastened by the fastening member 5 that enables the fastening work from the front side or lower side. This makes it possible to attach and detach the drain hose 40 from the front side or lower side of the air conditioning indoor unit 1, and facilitates removal of the first drain pan 30a from the casing 100. In this way, the air conditioning indoor unit 1 according to the present disclosure improves in maintainability. Alternatively, during maintenance, it may be necessary to remove the drain hose in order to check for hose clogging or water leakage in the drain hose. Even in such a case, the air conditioning indoor unit 1 according to the present disclosure enables attachment and detachment work of the drain hose 40 from the front side or lower side of the air conditioning indoor unit 1, and therefore the maintainability improves. (4-2) The air conditioning indoor unit 1 according to the present disclosure includes the casing 100. In the air conditioning indoor unit 1 according to the present disclosure, the fastening member 5 is disposed at a position where the fastening work is enabled by removing the front plate 101, the upper plate 102, the lower plate 103, and the side plate 104 of the casing 100. In this way, facilitating access to the fastening member 5 improves the maintainability of the air conditioning indoor unit 1. (4-3) The condensation water flowing through the outlet 31 has a low temperature. Therefore, if the heat insulating property is not ensured on the outer surface of the outlet 31, dew condensation may occur on the outer surface of the outlet 31. If the outlet 31 and the first member 50 are directly fastened, the first member 50 may cause dew condensation. As shown in FIG. 2B, the air conditioning indoor unit 1 according to the present disclosure includes the heat insulating member 70. The heat insulating member 70 covers the outer surface of the outlet 31. This secures the heat insulating property of the outer surface of the outlet 31. As shown in FIG. 2A, the first member 50 is fixed to the body 35 to avoid coming into direct contact with the outlet 31. This secures the heat insulating property of the first member 50. As shown in FIGS. 3 and 15, thefirst member 50 and the second member 60 according to the present disclosure are disposed to enable the fastening work in the outer space of the heat insulating member 70. This makes it possible to execute the fastening work without going through processes such as removing the heat insulating member 70, and to suppress a decrease in maintainability. The above-described configuration allows the air conditioning indoor unit 1 according to the present disclosure to secure the heat insulating property of the outer surface of the outlet 31 and the first member 50, and to suppress the decrease in maintainability.

(4-4) To cause the condensation water to flow out of the target space SP, the drain hose 40 extends in the rear-and-down direction when viewed from the front side of the air conditioning indoor unit 1 and is connected to the first drain pan 30a. The first member 50 and the second member 60 are fixed to the body 35 and the first end 41a along the drain hose 40 extending in the back-and-down direction. Therefore, 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 (if the first plate-shaped part 50a and the second plate-shaped part 60a are flush with the first adjacent part 50b and the second adjacent part 60b), respectively, it is necessary to tighten the fastening member 5 from the front-and-up direction when fastening the first member 50 and the second member 60 with the fastening member 5, and therefore the maintainability decreases. As shown in FIGS. 9 and 12, thefirst plate-shaped part 50a and the second plate shaped part 60a according to the present disclosure are inclined with respect to the first adjacent part 50b and the second adjacent part 60b, respectively. In more detail, the first plate-shaped part 50a and the second plate-shaped part 60a are inclined such that the tightening direction of the fastening member 5 is along the horizontal direction (to be perpendicular to the floor of the target space SP) when fastened by the fastening member 5. When the first plate-shaped part 50a and the second plate-shaped part 60a are inclined in this way, as shown in FIG. 15, the removal direction and tightening direction of the fastening member 5 are along the horizontal direction, facilitating the fastening work of the fastening member 5. This improves maintainability of the air conditioning indoor unit 1.

(4-5) As shown in FIGS. 3 and 15, the fastening member 5 according to the present disclosure is disposed in the space below the first drain pan 30a when viewed from the front side of the air conditioning indoor unit 1. In this way, the first member 50 and the second member 60 are fastened in the space below the first drain pan 30a, thereby allowing the air conditioning indoor unit 1 according to the present disclosure to save space in the right-and left direction in the three-dimensional space of the casing 100. (4-6) As described above, the first member 50 and the second member 60 are fastened by the fastening member 5 passing through the second through hole 502 and the third through hole 601. At this time, if the first member 50 is fixed to the first drain pan 30a, 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 overlap each other, then it is necessary to adjust the positions of the second through hole 502 and the third through hole 601 by a method 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 a method, the reliability of the drain hose 40 may decrease. The fitting portion 60c according to the present disclosure fits loosely with the drain hose 40. This allows the second member 60 to go around in the rotation direction of the drain hose40. Therefore, even if the positions of the second through hole 502 and the third through hole 601 do not overlap each other, the positions of the second through hole 502 and the third through hole 601 can be easily adjusted by causing the second member 60 to go around. The above-described configuration allows the air conditioning indoor unit 1 according to the present disclosure to improve the maintainability while suppressing the decrease in the reliability of the drain hose 40. (5) Modification (5-1) Modification A The above-described embodiment has described the example in which, for the purpose of adjusting the tightening direction of the fastening member 5 along the horizontal direction during maintenance, the first plate-shaped part 50a is inclined with respect to the first adjacent part 50b, and the second plate-shaped part 60a is inclined with respect to the second adjacent part 60b. However, the configuration of the first plate-shaped part 50a and the second plate shaped part 60a according to the present disclosure is not limited to this configuration, and may be, for example, the configuration in which the first plate-shaped part 50a is inclined with respect to the first adjacent part 50b and the second plate-shaped part 60a is not inclined with respect to the second adjacent part 60b, or the configuration in which the first plate-shaped part 50a is not inclined with respect to thefirst adjacent part 50b, and the second plate-shaped part 60a is inclined with respect to the second adjacent part 60b. In the former case, the second member 60 is fixed to the drain hose 40 to have an angle perpendicular to the floor of the target space SP, thereby causing the tightening direction of the fastening member 5 to be along the horizontal direction. In the latter case, the first member 50 is fixed to the first drain pan 30a to have an angle perpendicular to the floor of the target space SP, thereby causing the tightening direction of the fastening member 5 to be along the horizontal direction. In this way, even if either the first member 50 or the second member 60 is not inclined, the maintainability can be improved by adjusting the angle at which the first member 50 or the second member 60 is fixed.

The embodiment of the present disclosure has been described above. It will be understood that various changes to modes and details can be made without departing from the spirit and scope of the present disclosure recited in the claims.
