2. Description of the Related Art FIG. 9 is a side sectional view and a perspective view showing an indoor unit of a conventional air conditioner. In the figure, 1 is an indoor unit main body, and a base 2 is a component that is locked to the installation plate 3 when the indoor unit main body 1 is installed on a wall. A locking portion 2g is provided on the base 2, and the locking portion 2g serves as a support for fixing the indoor unit body 1 to the wall surface. A locking space 2b is provided on the front surface of the locking portion 2g, and a hook portion 3a protruding forward of the installation plate 3 is engaged with the locking space 2b to support the front of the unit body.

Both ends of the engaging portion 2g are integrated with the base 2. The installation plate 3 is fixed to the wall with screws or the like to support the unit body 1. Further, the indoor unit body 1 is supported by the receiving plate 2h on the installation plate 3 under a vertical load. The heat insulating material 8 prevents dew condensation on the surface of the indoor unit main body 1 that is cold during cooling, and is made of a foam material or the like.

FIG. 10 is a side sectional view showing a state of installation work of an indoor unit of a conventional air conditioner. In the figure, a holding member 5 is provided between the installation plate 3 and the base 2 in order to connect the pipe 4 to the pipe of the outdoor unit.
Is supported by inclining. The fall prevention ribs 2a are for preventing the tilted state of the unit body 1 from being displaced upward, and have a shape in which a bent front bent portion 3b is applied to the front surface of the upper end of the installation plate 3. There is. At that time, the unit body 1 is supported by the receiving surface 2h. Further, the locking space 2b has a penetrating shape whose upper and lower sides are open because the locking portion 2g and the fall prevention rib 2a are formed by molding with a mold.

Next, the operation will be described. As shown in FIG. 9, the indoor unit body 1 is fixed to the wall surface by engaging the locking portion 2g of the base 2 with the hook portion 3a of the installation plate 3 fixed to the wall by screws. At that time, the unit body 1 is supported by the receiving surface 2h. The locking portion 2g is thus the hook portion 3
Since a is locked, a locking space 2b is formed in the front surface. In order to perform the connection work of the pipe 4 while being supported in this way, it is necessary to incline the unit body 1 as shown in FIG.

For that purpose, the indoor unit main body 1 is supported by the holding member 5 between the installation plate 3 and the base 2 and held in an inclined state.
At this time, it is necessary to prevent the indoor unit body 1 that is held inclined from coming into contact with the operator's body and falling off the installation plate 3. For this reason, the fall prevention rib 2a is engaged with the front bent portion 3b bent forward at the upper end of the installation plate 3. Also,
The locking space 2b has a vertically penetrating shape in order to form the falling prevention rib 2a and the locking space 2b by molding using a mold.

[0007]

Since the indoor unit of the conventional air conditioner is constructed as described above, it is impossible to form a strong shape due to the locking space 2b which penetrates vertically. There is a problem that oily matter floating in the atmosphere passes through the opening of the locking space 2b and adheres to the locking portion 2g with the installation plate 3, which causes material deterioration.

Further, when the indoor unit body 1 is hung on the installation plate 3, the front bent portion 3b is bent to the front surface of the upper part of the installation plate 3.
There is also a problem in that there is a high possibility that the heat-insulating material 8 on the back surface of the indoor unit body 1 will hit and be damaged.

The present invention has been made in order to solve the above-mentioned problems, and by eliminating the hole structure in the upper part of the indoor unit body, material deterioration is suppressed and the engagement with the installation plate of the indoor unit body is suppressed. It is an object of the present invention to provide an indoor unit for an air conditioner that improves the strength of parts, does not bend the installation plate shape to the front, and reduces damage to the heat insulating material.

Further, by eliminating the hole structure in the upper part of the device body, the deterioration of the material is suppressed, the strength of the engaging part of the device body with the installation plate is improved, and the installation plate shape is not bent to the front. An object of the present invention is to provide a device installation structure that can reduce damage to the heat insulating material.

It is another object of the present invention to provide an installation plate which is not bent to the front surface and can reduce damage to the equipment.
