DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an air conditioner according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view of an indoor unit showing an embodiment of an installation structure of an air conditioner according to the present invention.
FIG. 2 shows a perspective view thereof. The indoor unit of the air conditioner
An upper surface cover 5 provided with a suction grille 4 forming a suction opening 3 is provided on an upper front surface of a base 2 having an open front surface of the indoor unit 1 body. A front heat exchanger 9a and a rear heat exchanger 9b each having a side plate 8 fixed to a support portion of the base 2 in an air passage connecting the inlet 3 and the outlet 6 with the curved front covers 7 attached thereto. To provide an inverted V-shaped heat exchanger 9 and a blower fan 10, and a hook 13 having an L-shaped cross section, which is fixed to a rear upper portion of the base 2 by being hooked to an installation fitting 12 fixed to a wall 11. It has. The heat exchanger 9, which is a main component of the indoor unit 1, is fixed to the base 2, and includes a blower fan 10, a fan motor for driving the fan 10, a control board (neither is shown), or the like. Such components are also fixed to the base 2. In this way, most of the heavy parts are incorporated into the base 2 which comes into contact with the wall 11 via the mounting hardware 12.

Therefore, as a method for installing the indoor unit 1 on the ceiling 14, the indoor unit 1 is suspended from the ceiling 14 via left and right side plates 8 provided at both ends of the heat exchanger 9 in this embodiment. . The indoor unit 1 is attached to the ceiling 14.
From the front and back, one end of which is fixed to the ceiling,
A total of four installation bolts 15 (two on the left and right)
It is provided to be hung from. In addition, the hanging bracket 16 as the second mounting bracket is formed by bending a flat plate made of a steel plate into a Z-shaped cross section, and having two bent holes 16a through which the bolt 15 is inserted into one bent surface and the other bent surface. And two insertion holes 16b for fastening with the bolts 18 provided on the reinforcing bracket 17 provided in the indoor unit 1.

In this embodiment, a reinforcing plate 17 is formed by bending a single steel plate. The first mounting portion is a rectangular flat plate provided with two insertion holes provided on the bent surface of the hanging bracket 16. 1
A screw hole 17b corresponding to 6b is provided. The screw hole 17b is formed by welding a corresponding nut 17a to the lower surface of the through hole provided in the first mounting portion. Further, the second mounting portion is suspended from both ends of the first mounting portion, and each flange 8a, 8b vertically protrudes in the left-right direction from the side plate 8 of the front heat exchanger 9a and the rear heat exchanger 9b. Are two rectangular flat plates corresponding to
It is fixed to each flange by a book screw 19. The reinforcing metal member 17 as described above is disposed between the inner surface of the upper cover 5 and the heat exchanger 9. Here, the flange portion and the second mounting portion may be welded instead of being fixed with the screw 19, or the side plate 8 and the reinforcing bracket 17 may be integrally formed. With such a structure, it is possible to reduce the relatively troublesome work of fixing the side plate 8 and the reinforcing bracket 17. Further, in this embodiment, the first mounting portion is in contact with the inner surface of the suction grille 4. Further, the insertion hole 16 b and the screw hole 17 b are arranged so as to overlap with the air passage of the suction grill 4. Therefore, the insertion hole 16b of the hanging bracket 16 and the screw hole 17 of the reinforcing bracket 17 are provided.
b, the hanging bracket 16 and the reinforcing bracket 17 are fixed to the suction grill 4 by bolts 18, the bolt 15 is inserted through the insertion hole 16 a of the hanging bracket 16, and the nut 20
, The indoor unit 1 can be fixed to the ceiling 14.

As described above, the indoor unit 1 is sandwiched by the suction grill 4.
When mounting as a wall-hanging type, the metal fittings necessary for ceiling-hanging are not exposed from the indoor unit 1 and the ceiling-hanging or wall-mounting can be arbitrarily selected at the installation site. Can be installed. For this reason, it is not necessary to manufacture a dedicated model for each model, and a single model can be manufactured, so that production efficiency can be improved. In addition, since the second mounting portion of the reinforcing metal member 17 is divided and fixed to the flanges 8a and 8b of the side plate 8 corresponding to the front heat exchanger 9a and the rear heat exchanger 9b, respectively, Since the weight can be dispersed, the strength of the side plate 8 can be maintained, and the indoor unit 1 can be hung before and after the center of gravity of the indoor unit 1, a stable installation structure can be obtained. Further, since an insertion hole of the upper surface cover 5 necessary for inserting a bolt 18 for fixing the hanging metal member 16 and the reinforcing metal member 17 is used as an air passage of the suction grille 4, a special hole is not provided, and a wall-mounted type. Even if it is installed as, it is possible to keep the appearance without a sense of incongruity.
