The indoor unit 100 has an indoor heat exchanger 110 . The indoor heat exchanger 110 exchanges heat between the air to be air-conditioned in the air-conditioned space I, which will be described later, and the refrigerant. The indoor heat exchanger 110 functions as an evaporator during cooling operation and evaporates the refrigerant. Indoor heat exchanger 110 functions as a condenser during heating operation, and condenses and liquefies the refrigerant.

Indoor unit 100 is an example of a refrigeration cycle unit of a refrigeration cycle device. In Embodiment 1, the indoor unit 100 is an indoor unit of a ceiling-embedded air conditioner in which the majority of the indoor unit 100 is embedded in a non-air-conditioned space O, which will be described later, behind the ceiling, and conditioned air is blown out from the ceiling surface.

The outdoor unit 200 has a compressor 210 , a four-way valve 220 , an outdoor heat exchanger 230 and an expansion valve 240 .

Compressor 210 compresses and discharges the sucked refrigerant. Compressor 210 may arbitrarily change the operating frequency by, for example, an inverter circuit or the like to change the capacity of compressor 210 to send out refrigerant per unit time.

The four-way valve 220 is a valve that switches the flow of refrigerant between cooling operation and heating operation.

The outdoor heat exchanger 230 exchanges heat between the refrigerant and the outdoor air. The outdoor heat exchanger 230 functions as a condenser during cooling operation, and condenses and liquefies the refrigerant. The outdoor heat exchanger 230 functions as an evaporator during heating operation and evaporates the refrigerant.

The expansion valve 240 is a flow control valve that reduces the pressure of the refrigerant to expand it. When the expansion valve 240 is composed of, for example, an electronic expansion valve, the degree of opening can be adjusted based on an instruction from a control device (not shown) or the like.

By configuring the air conditioner 500 as described above, the flow of the refrigerant is switched by the four-way valve 220 of the outdoor unit 200, and cooling operation or heating operation can be realized.

FIG. 4 is an exploded perspective view showing the cover 1 according to Embodiment 1. FIG. FIG. 5 is a cross-sectional view showing the cover 1 according to Embodiment 1. FIG. In addition, the cross section of the cover 1 of FIG. 5 is a cross section along the front direction F and the back direction B. As shown in FIG. As shown in FIGS. 4 and 5, the cover 1 is composed of two parts, a fixed plate 2 and a rotating plate 3. As shown in FIGS.

As shown in FIG. 4, the fixed plate 2 has an opening 4, a bearing 5a, a bearing 5b, a screw hole 9a, a screw hole 9b, a screw 11a and a screw 11b. The screws 11a and 11b are fixing members. The rotating plate 3 has a shaft portion 6 and a claw portion 7 . The shaft portion 6 is configured by a rod-shaped body. The shaft portion 6 rotates the rotating plate 3 from the fixed plate 2 . The claw portion 7 enters the opening portion 4 of the fixed plate 2 . The claw portion 7 has a locking portion 8 formed by extending the tip of the claw in an inverted U-shaped curve. The claw portion 7 has a snap-fit structure that is locked to the fixed plate 2 using elastic deformation of the locking portion 8 .

The edge of the fixed plate 2 on the front direction F side does not protrude from the pipe installation wall 16a. An opening 4 is formed in the fixing plate 2 . The opening 4 of the fixing plate 2 is connected to the space A from the portion facing the fixing plate 2 . The space A is formed between the drain pan 10 and the lower surface 17a of the main body 17 to which the fixing plate 2 is fixed. The locking portion 8 of the cover 1 is inserted into the space A when the claw portion 7 is locked.

The rotary plate 3 is rotatably attached to the fixed plate 2 so as to protrude in the front direction F away from the pipe installation wall 16a. The rotating plate 3 rotates about the shaft portion 6 fitted in the bearing portion 5a and the bearing portion 5b. When the rotating plate 3 rotates, the claw portion 7 is pushed from the state shown in FIG. As a result, the engaging portion 8 is elastically deformed in the rearward direction B so that the tip of the nail approaches the base of the nail. Then, the claw portion 7 is separated from the edge of the opening portion 4 in the front direction F. As a result, the rotary plate 3 can move downward D from the fixed plate 2 .

As shown in FIG. 4, a screw 11a is inserted through the screw hole 9a and screwed to the lower surface 17a of the main body 17 shown in FIG.

FIG. A first blowout port 52 indicated by a dashed line in FIG. 8 overlaps the second blowout port 15a and extends into the space S outside the pipe installation wall 16a. Therefore, the length of the second outlet 15a along the side surface of the main body 17 is shorter than the length of the first outlet 52 corresponding to the second outlet 15a.

Based on the positional relationship between the first outlet 52 and the second outlet 15a, when the decorative panel 50 is attached to the main body 17, the opening portion 14 of the first outlet 52 of the decorative panel 50 becomes the adjacent portion 16b. protrudes to the space S side. As a result, air flows between the non-air-conditioned space O and the air-conditioned space I through the partial opening 14 of the first outlet 52 of the decorative panel 50 .

Therefore, the rotating plate 3 of the cover 1 blocks the opening portion 14 of the first outlet 52 extending outward from the piping installation wall 16a. Thereby, the cover 1 blocks the flow of air between the non-air-conditioned space O and the air-conditioned space I. As shown in FIG. Therefore, it is possible to prevent turbulence in the airflow during operation of the air conditioner 500 in the air-conditioned space I, and achieve a desired air-conditioned temperature.

As shown in FIG. 9, the fixing plate 2 of the cover 1 is fixed to the lower surface 17a of the main body 17. As shown in FIG. The fixed plate 2 is fixed to the lower surface 17a of the main body 17 using screws 11a and 11b. The mounting positions of the screws 11a and 11b are formed by narrowing the lateral width of the rotary plate 3 with respect to the fixed plate 2. As shown in FIG. As a result, the screws 11a and 11b are attached to the fixed plate 2 at positions where the rotary plate 3 is cut away so as not to overlap the rotary plate 3. As shown in FIG.

FIG. 10 is a bottom view showing a state in which the rotating plate 3 of the cover 1 according to Embodiment 1 is rotated downwardly D by 90 degrees from the fixed plate 2 . As shown in FIG. 10, the fixing plate 2 does not protrude outward in the front direction F from the pipe installation wall 16a. When the rotary plate 3 is rotated in the downward direction D away from the fixed plate 2, the pipe installation wall 16a can be confirmed from the lower surface side of the main body 17, which is the direction in which the rotary plate 3 is rotated. Therefore, when the rotary plate 3 is rotated in the downward direction D away from the fixed plate 2, the operator can visually recognize the wiring inlet 13 and the pipe connection portions 12a and 12b from the downward direction D.
