[0002]

2. Description of the Related Art In general, a wall-mounted air conditioner is known in which a pipe connecting portion between an indoor heat exchanger and an outdoor heat exchanger is arranged behind a frame bottom plate forming an air outlet of an air conditioner. Have been. In this type of conventional wall-mounted air conditioner, first, a back plate is fixed to the indoor wall, an upper edge of the air conditioner is hooked on an upper end of the back plate, and then a lower edge of the air conditioner and a back plate are attached. Is inserted between them, a tool is inserted into a space formed therein, and a pipe nut is tightened.

[0003]

However, according to the above-mentioned conventional mounting method, it is difficult to mount the air conditioner. In addition, after the air conditioner is mounted, the interval maintaining rod is removed and the air conditioner is mounted on the back plate. When installing the air conditioner, there is a problem that the air conditioner is not mounted exactly on the back plate and the air conditioner is mounted in a floating state.

Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art and to provide a wall-mounted air conditioner and an air conditioner which can attach an air conditioner to a back plate not in a floating state but in a tight manner. An object of the present invention is to provide an attachment method.

[0005]

According to the first aspect of the present invention, a pipe connecting the indoor heat exchanger and the outdoor heat exchanger is connected to the back of a frame bottom plate forming an air outlet of an air conditioner. in part it was placed wall-hanging type air conditioner, the indoor

Oite the mounting method of the type air conditioner, a drain pan disposed under the <br/> indoor heat exchanger, a discharge frame for supporting the air direction changing blade on the lower surface to support the drain pan to the top surface, the A structure formed integrally with a bottom plate of a frame, a lower cover of the frame, and the frame
It is characterized in that the pipes are connected in a state where the front cabinet is removed and the pipes are exposed below the frame.

[0009]

According to these inventions, the cabinet and the drain on the lower portion of the frame , the front surface, and the drain are all connected when the pipe is connected.
Since the pan, the discharge frame, and the like are removed to expose the connecting portion of the pipe, the pipe connecting operation becomes extremely easy, and the lifting of the frame is almost certainly suppressed.

[0011]

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a wall surface in a room, and a back plate 2 is fixed to the wall surface 1 using a plurality of screws. A locking body 2a protrudes from an upper end of the back plate 2, and an upper edge 100a of a frame 100 (FIG. 2) of the wall-mounted air conditioner 3 is hooked on the locking body 2a. After the upper edge 100a is hooked on the frame 100, the back plate 2 is formed using a plurality of screws (not shown).
It is fixed to.

Referring to FIG. 2, a control box 6, a blower 7, a motor 8, a refrigerant heat exchanger (indoor heat exchanger) 5, a hot water heat exchanger 5A, and a drain pan 17
Further, referring to FIG. 1, the air purifier 9 and the vertical blade 2
1 and the horizontal blade 25 are housed. In addition, with reference to FIG. 2, 7a is a bearing, 7b is a bearing cover.

As shown in FIG. 2, a cabinet 101, a filter 103 and a front panel 105 are mounted on the front surface of the frame 100, and a frame lower cover 107 is mounted on the lower surface of the frame 100. Further, as shown in FIG. 1, a suction port 11 is formed on the front and diagonally above the air conditioner 3, and an air outlet 13 is formed on the diagonally lower front of the air conditioner 3.

As shown in FIG. 1, the outlet 13 is connected to an outlet passage 19 inside the frame 100, and the outlet passage 19 guides air from the blower 7 to the outlet 13. The outlet passage 19 is surrounded by the discharge frame 109 and the frame bottom plate 15. The above ejection frame 10
9 has a drain pan 17 on its upper surface according to this embodiment.
The lower surface supports a wind direction changing blade composed of a vertical blade 21 and a horizontal blade 25, and a frame bottom plate 15 is integrally connected to the discharge frame 109.

On the back side of the frame bottom plate 15, a refrigerant large tube 111, a refrigerant thin tube 113, and a drain hose 115 for connecting the refrigerant heat exchanger 5 and an outdoor heat exchanger (not shown), and a drain hose 115 are further shown. A hot water inlet pipe 117 and a hot water outlet pipe 119 for connecting the heat source unit and the hot water heat exchanger 5A are omitted.

According to this embodiment, the refrigerant heat exchanger 5
In addition to the above, since a hot water heat exchanger 5A is provided, it is possible to respond to a large heating load and, for example, air dehumidified by the refrigerant heat exchanger 5 can be reheated by the hot water heat exchanger 5A and blown out. Dehumidification can be performed without lowering the pressure.

However, as described above, the frame bottom plate 1
5 has five tubes 111, 113, 115, 11
Since 7, 119 are arranged, the operation of connecting these tubes by conventional methods is extremely difficult.

Therefore, according to this embodiment, when this wall-mounted air conditioner is installed on a wall surface, first, as shown in FIG. The frame 100 containing the exchangers 5 and 5A is fixed. At this time, a refrigerant pipe is introduced from outside through the wall surface 1. Then, the lower cover 107 of the frame 100
Then, the cabinet 101 on the front of the frame 100 is removed. Furthermore, the drain pan 17 disposed below the heat exchanger supports this drain pan to the top surface, a bottom plate 1 of the discharge frame 109 and the frame 100 for supporting the air direction changing blade to the lower surface
5 is removed integrally.

As described above, when connecting the pipes,
Remove the vignette 101 and the lower cover 107 and
By removing the serial structure, as shown in FIG. 3, the heat exchanger
The drain pan 17 arranged at the lower part,
Supports the wind direction changing blades 21 and 25 on the upper surface and on the lower surface
The bottom plate 15 of the discharge frame 109 and the frame 100 comes off,
The space of the pipe section is large, and the pipes 111, 113, 115, 11
Since the connecting portions 120 of the wires 119 are exposed, the work of connecting them is extremely easy as compared with the conventional one.

According to this embodiment, after the frame 100 is fixed to the back plate 2, these pipes can be connected. Therefore, as in the conventional case, the pipes are connected by floating the frame 100 one by one. Since there is no work for bringing the frame 100 into close contact with the back plate 2, the lifting of the frame 100 is suppressed. In the above, the installation of the air conditioner has been described. However, according to this embodiment, even in the case of cleaning or replacing the blower 7, the same operation as described above is performed.
Pipes 111, 113, 11
5, 117 and 119 are exposed and these pipes may be connected, so that maintenance of the blower 7 and the like become easy.

Further, according to this embodiment, by removing the lower cover 107, the pipe connection status can be visually checked.

[0023]

As is apparent from the above description, according to the present invention, the connecting portion can be exposed at the lower portion of the frame when connecting the pipe, so that the pipe connecting operation becomes extremely easy, and the frame is lifted. Can be suppressed.
