DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an air conditioner embedded in a ceiling.

[0002]

2. Description of the Related Art A conventional air conditioner is shown in FIGS. In the figure, 51 is an air conditioner, 52 is a decorative panel attached below the air conditioner, 53 is a ceiling surface, 54 is a ceiling base, and 55 is a suspension bolt attached to the ceiling base. The outer shell of the air conditioner 51 is
It is made of sheet metal, and a plurality of hanging
Is provided, and a refrigerant pipe 57 and a drain pipe 58 are led out on one side. Further, the air conditioner 51 is fixedly suspended above and below the suspension fitting 56 by a suspension bolt 55 via a nut 59, and the refrigerant pipe 57 and the drain pipe 58 are connected to respective pipes constructed on site. Then, after the room air is sucked in through the decorative panel 52 and heat exchange is performed, the air is blown out again to operate.

[0003]

When such a conventional air conditioner 51 is to be hung by a single person on the suspension bolts 55, the ends A and B of the outer shell of the air conditioner 51, Or, put a hand on the hanging bracket 56 and
Is lifted, and the hanging metal fittings 56 are sequentially placed on the nut 59 below the hanging bolts 55 one by one. However, since there is no grip at both ends of the outer shell, it is difficult to hold the air conditioner 51,
In addition, when the user holds the hanging metal fitting 56, the hand hinders the work when the hanging metal fitting 56 is inserted into the hanging bolt 55, resulting in lack of workability. Therefore, the hanging operation by one person is difficult, and it is necessary to work by two or more people. Also, when the air conditioner 51 is transported before the hanging operation, the transportability is inferior because the handling portion is similarly small. Further, since the outer shell is made of sheet metal, its end face may be exposed, which is inferior in safety.

An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide an air conditioner having good workability and transportability and high safety.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a structure in which handles are formed on both sides of the air conditioner provided with hanging brackets. By supporting each handle so that the air conditioner is sandwiched by one hand at the time of the work, the air conditioner can be held easily and securely, and the work of hanging the air conditioner becomes easier and Workability is similarly improved for work.
