Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a ceiling-embedded air conditioner that is suspended and installed in the ceiling.

Conventional structure and its problems Conventionally, the mounting structure of an air conditioner that is hung in the ceiling is as shown in Figure 1 a, b, and c, by fixing a hanging bolt A to a beam B in the ceiling F. The main body D is mounted in the ceiling by fixing the hanging bolt A to a substantially L-shaped hanging fitting E provided opposite to the side surface of the air conditioner main body D which is inserted through the opening F'.

Furthermore, it is difficult to install the beam B in the ceiling F where the beam B is uneven or where many other construction pipes intersect with each other. Therefore, the installer has to select various installation locations, which has the disadvantage that air conditioning of the necessary areas becomes impossible.

Purpose of the invention Therefore, the present invention aims to provide a ceiling-embedded air conditioner that allows the main body to be easily installed even when the beam in the ceiling where the hanging bolts are installed is uneven or there are other construction pipes in the ceiling. This is the purpose.

Structure of the invention In order to achieve this purpose, the main body of the air conditioner is made into a cross-shaped box with open corners, and the hanging fittings are selectively fixed to one side of the auxiliary side plates forming a substantially right angle. The mounting position of the hanging bolt inside the ceiling is made variable, so that it can be mounted while dealing with irregularities such as beams inside the ceiling and other construction piping.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

Reference numeral 1 denotes a ceiling-mounted air conditioner main body, which consists of a box body 4 with an open bottom surface in which a heat exchanger 2, a blower 3, etc. are sequentially arranged inside, and a decorative grille 5 attached to the bottom surface of this box body 4. . This grill 5 has a discharge port 6 and a suction port 7 formed therein. The box body 4 is an air-conditioned room 8
A hanging bolt 11 is inserted through an opening 9' drilled in the ceiling 9 of the building and is suspended from a beam 10 in the ceiling 9.
On the other hand, a hanging fitting 12 fixed to the box body 4 is inserted and fixed to be placed in the ceiling.

That is, the box body 4 includes a top plate 4a, side plates 4b and 4c that form a long side and face each other, side plates 4d and 4e that form a short side and face each other, and adjacent side plates 4b and 4d, 4d and 4c, Substantially right-angled auxiliary side plates 4f, 4 connecting the end faces of 4c and 4e, and 4e and 4b.
g, 4h, and 4i form a cross shape. In other words, a rectangular space is formed at the corner of the rectangular box.

In addition, the hanging fittings 12 are attached to each of the above-mentioned auxiliary side plates 4f to 4i.
is selectively fixed with a screw 13 to one of the surfaces forming a right angle to the fixing surface fixed with the screw 13, and a hole 12 through which the above-mentioned hanging bolt 11 passes.
a, and is formed into a substantially L-shape with a support surface fixed with a nut. The protruding length of the supporting surface or the size of the space is set so that the hanging fitting 12 is located within the space formed by the auxiliary side plates 4f to 4i, that is, within the space formed by the extension of the side plates 4b to 4e. ing. Furthermore, the hanging fitting 12 can be attached not only to one side of the auxiliary side plates 4f to 4i, but also to the other adjacent side as shown by the two-dot broken line in FIG.

Reference numeral 13 designates a pipe connection port and a drain connection port that similarly protrudes within the space on one side of the auxiliary side plate 4f.

In the above configuration, the box 4 is connected to the opening 9' in the ceiling 9.
When it is inserted further, since the hanging fitting 12 does not protrude from the box body 4, the opening 9' may be a minimum opening approximately the same size as the rectangular outer shape formed by the side plates 4b to 4e and their extensions. . Furthermore, as shown in FIG. 2a, even if there is an uneven shape 10' of the beam 10 in the ceiling, the hanging bolt 11 is fixed while avoiding this.
To match this, attach the hanging bracket 12 to the auxiliary side plate 4f.
It is best to change it to the next side of ~4i. Furthermore, the hanging bolts 11 can be fixed even when there are other pipes 15 on the beams 10 in the ceiling, and the mounting of the hanging fittings 12 can be selected depending on the installation location in the ceiling.

Effects of the invention As is clear from the above explanation, in the ceiling-embedded air conditioner of the present invention, the hanging metal fittings are installed on the auxiliary side panels that form the corner spaces of the box, so when installing the main unit, it is necessary to drill holes in the ceiling. The opening can be kept to a minimum, and it is also possible to install the main body in close contact with a wall in the ceiling. In addition, by selectively attaching the hanging fittings to either of the substantially perpendicular surfaces of the auxiliary side plates, it is possible to avoid uneven shapes such as beams and other piping.
