DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit of a separation type air conditioner in which a storage space for an auxiliary pipe is formed in a lower portion of a housing.

[0002]

2. Description of the Related Art An indoor unit of a separation type air conditioner in which a storage space for an auxiliary pipe is formed at a lower portion of a housing is described in, for example, Japanese Utility Model Publication No. 63-40731.
This publication discloses a cutout for connecting an auxiliary pipe and a pipe between units in a bottom plate of a housing of an indoor unit, and a pipe which is detachably attached from below the unit to close the cutout. And a cover.

[0003]

In the above-mentioned indoor unit, since the auxiliary piping and the piping between the units are not held down, there is a risk that the lower part of the housing of the indoor unit may float or the pipe cover may come off.

[0004] The present invention provides an indoor unit in which the lower part of the housing of the indoor unit is prevented from being lifted up and the pipe cover is prevented from coming off.

[0005]

Means for Solving the Problems A heat exchanger and a blower are housed in a housing attached to a wall surface in a room, and a space along an inner wall of a bottom plate of the housing is housed in a refrigerant pipe connected to the heat exchanger. Space, and the bottom plate of the housing was housed in this storage space in an indoor unit of a separation-type air conditioner provided with a cutout for connection of the refrigerant pipe and a pipe cover closing the cutout. A plurality of retainers for the refrigerant pipes are provided, and the lower ends of these retainers are removably attached to the lower part of the storage space, and the upper ends thereof are rotatably fixed to the upper part of the storage space,
One of these holding members is made to face the notch, and the other holding member is made not to face the notch.

[0006]

When connecting the refrigerant pipes of the indoor unit of the separation type air conditioner having the above-described structure, one presser acts as a presser for the refrigerant pipes, and the other pressers are used for the housing. The bottom plate acts as a spacer to float off the wall surface.

[0007]

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

FIGS. 1 and 2 show an indoor unit 1 of a separation type air conditioner according to the present invention. Reference numeral 2 denotes a housing which is attached to a wall surface of a room and accommodates a heat exchanger (not shown), a blower and the like. The space below the bottom plate 3 along the inner wall of the bottom plate 3 is a storage space for the refrigerant pipe 4 connected to the heat exchanger. The bottom plate 3 of the housing 2 has a cutout for connecting the refrigerant pipe 4 and a detachable pipe cover 5 for closing the cutout.
Are provided. 6 is a hook piece hooked on an installation plate 8 (see FIG. 5) previously installed on a wall surface 30 in the room;
7 is a drain hose for discharging drain from a drain pan, 8 is a drain receiver for receiving drain on the back of the housing 2,
9 is a refrigerant pipe 10 connecting the refrigerant pipe 4 and the outdoor unit.
A presser for pressing [see FIG. 3] faces the notch. Therefore, when the pipe cover 5 is removed, the presser 9 can be seen. Reference numeral 11 denotes a presser for pressing the refrigerant pipe 4 into the storage space from the rear side of the housing. Reference numeral 13 denotes an air outlet formed on the lower front side of the housing 2, to which a wind direction plate (not shown) is attached. Reference numeral 14 denotes an opening for a radiation sensor.

FIGS. 3 and 4 are a sectional view taken along the line III-III and a sectional view taken along the line IV-IV shown in FIG. The holding member 9 includes a shaft 9 a rotatably stopped by the stopper 15, a holding portion 9 b for holding the refrigerant pipe 10 from the rear side of the housing 2, and a cooling pipe 10 from the pipe cover 5 side of the housing 2. A holding portion 9 c for holding and a hook 9 d hooked on the lower portion of the housing 2 are formed. The retainer 11 is hooked on a shaft 11 a rotatably stopped by the stopper 12, a retainer 11 b for retaining the refrigerant pipe 4 from the rear side of the housing 2, and a bottom plate 3 a on the storage space side of the housing 2. A hook 11c is formed. 16
Is a casing for forming a passage for the blown air, and 17 is a blower for blowing air that has passed through the heat exchanger.

[0010] The indoor unit 1 configured as described above includes:
In the case of a so-called left pipe in which the refrigerant pipe 10 is arranged from the through hole on the left rear side of the housing 2 toward the outdoor unit,
It is installed as follows.

First, the hook 6 is hooked on the installation plate 8 attached to the wall 30 in the room. Then, the pipe cover 5 is removed, the hook 9d of the presser 9 is detached from the lower part of the housing, the hook 11c of the presser 11 is detached from the bottom plate 3a and rotated, and the hook 11c side of the presser 11 is installed. The lower part of the housing 2 is floated from the mounting plate 8 against the plate 8 (see FIG. 5).
That is, the presser 11 functions as a spacer for lifting the lower part of the housing 2 from the wall surface. When the lower part of the housing 2 is lifted from the mounting plate 8 and the pipe cover 5 is removed, a large work space for connecting the refrigerant pipes 4 and the refrigerant pipes 10 is secured, so that the connection work can be performed very easily. Can be.

When the connection operation is completed, the holding member 9 is rotated to hook the hook 9d on the lower portion of the housing. In this state,
The refrigerant pipe 10 is pressed into the storage space from the rear side of the housing by the holding part 9b, and is pressed from the bottom side of the housing by the holding part 9c. For this reason, it is possible to prevent the lower part of the housing from being lifted up and the pipe cover 5 from being detached due to insufficient holding of the refrigerant pipe 10.

Next, when the holding member 11 is rotated to hook the hook portion 11c on the bottom surface 3a, the refrigerant pipe 4 is moved from the back side of the housing 2 into the storage space by the holding portion 11b of the hook member 11. The refrigerant pipe 4 is pressed by the bottom plate 3a on the storage space side from the bottom plate side of the housing. For this reason, it is possible to prevent the lower part of the housing 2 from being lifted due to insufficient holding of the refrigerant pipe 4.

As described above, the refrigerant pipe 4 in the storage space
Of the refrigerant pipe 10 and the holding member 9.
So that the refrigerant pipes 4 and 10 are held down,
Compared to the conventional case in which only the refrigerant pipe 4 was held,
Lifting of the lower part can be prevented as much as possible.

Finally, when the pipe cover 5 is attached to the cutout, the installation of the indoor unit 1 is completed.

[0016]

According to the present invention, a heat exchanger and a blower are housed in a housing attached to a wall surface in a room, and a space along an inner wall of a bottom plate of the housing is housed in a refrigerant pipe connected to the heat exchanger. Space, and the bottom plate of the housing was housed in this storage space in an indoor unit of a separation-type air conditioner provided with a cutout for connection of the refrigerant pipe and a pipe cover closing the cutout. A plurality of retainers are provided for the refrigerant pipe, and the lower ends of these retainers are removably attached to the lower portion of the storage space, and the upper ends thereof are rotatably fixed to the upper portion of the storage space. One of them faces the notch and the other retainer does not face the notch, so when connecting the refrigerant pipe, one presser facing the notch is As a retainer The remaining retainer that does not face the cutout can act as a spacer to raise the bottom plate of the casing from the wall surface, so the casing of the indoor unit caused by insufficient holding of the refrigerant pipes Lifting of the lower portion and detachment of the pipe cover can be prevented as much as possible.
