DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a casing of an air conditioner buried in a ceiling, and more particularly to a casing structure and a mounting structure of a heat insulating member.

[0002]

2. Description of the Prior Art FIG. 1 is a perspective view showing a casing of a conventional embedded air conditioner, FIG. 2 is an exploded perspective view showing a casing of the conventional embedded air conditioner, and FIG. 8 is an enlarged cross-sectional view of a main part showing an example of a casing of a ceiling-embedded air conditioner, FIG. 8 is an enlarged cross-sectional view of a main part showing an example of a casing of a conventional ceiling-mounted air conditioner, and FIG. FIG. 2 is an enlarged sectional view of a main part showing an example of a casing of the ceiling-mounted air conditioner of FIG.

[0003] Casing 1 of a conventional ceiling-mounted air conditioner
Is an L-shaped first side plate 2 having a mounting portion 2c at both ends, a flat bent portion 2b at a corner and a flange 2a bent inward at a bottom edge, and mounting portions 3c at both ends having the same shape. And a flat bent portion 3b at the corner and a flange 3 bent inside at the bottom edge
The L-shaped second side plate 3 having a shape a is screwed into the rising flange 4a of a base 4 having a bottomed square shape having a rising flange 4a on its outer periphery, and the inside of the base 4 is screwed. Further, a substantially cylindrical heat insulating member 5 having a bottom flange 5a corresponding to the bottom of the base 4 and an opening 5b in the center is mounted.

However, according to the casing 1 of the above-mentioned conventional ceiling-mounted type air conditioner, there is a problem that the strength is insufficient, the casing is twisted, and the quality may be deteriorated.

[0005] Fig. 8 shows a structure in which the base 4 is manufactured by drawing to improve the strength. In this case, the first curved surface of the first side plate 2 and the second curved surface of the second side plate 3 are smaller than the curved surface of the rising flange 4a of the base 4 because the angled curved surfaces of the flange 2a of the first side plate 2 and the flange 3a of the second side plate 3 are smaller. Is arranged on the outside.

For this reason, although the strength is ensured, the flange 2a of the first side plate 2 and the flange 3a of the second side plate 3 enter under the base 4, thereby deteriorating the workability of assembly and positioning. Is determined by the mounting holes of the screws, and there is a problem that the mounting accuracy of the first side plate 2 and the second side plate 3 is not obtained and the performance and quality of the main body may be greatly affected.

On the other hand, when mounting and moving the main body, the bottom of the base 4 is usually lifted up by hand, but a sheet metal such as the flange 2a of the first side plate 2 and the flange 3a of the second side plate 3 is placed at the handle position. There was also a problem that there was a risk in safety that the hand would be cut at this edge due to the presence of the edge.
On the other hand, as shown in FIG. 9, when the heat insulating member 5 made of soft styrene foam is bent at the time of mounting, there is a problem that the heat insulating member 5 may be caught on the screw and damaged.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and is a ceiling-mounted type air conditioner which ensures strength, improves accuracy, safety and assembly workability. It is an object to provide a casing of a machine.

[0009]

In order to solve the above-mentioned problems, a base formed in a substantially square shape and having a rising flange on a peripheral edge thereof, an L-shaped roughly formed base and a mounting portion and a bottom edge provided at both ends. A first side plate having a flange bent inward, and a second side plate, the attachment portion of the first side plate and the second side plate are joined to form a substantially cylindrical shape, and a screw is provided inside the rising flange. In a casing of a ceiling-mounted air conditioner, which is mounted with a substantially cylindrical heat-insulating member having a bottom flange corresponding to the bottom of the base and an opening at the center inside thereof, The corners of the flanges of the side plate and the second side plate are made larger than the corners of the rising flange of the base.

[0010] Further, a protection member for preventing contact between the protrusion of the screw into the base and the heat insulating member may be provided on each flange of the first side plate and the second side plate.

The protection member is a protection piece extending from each flange of the first side plate and the second side plate to an upper portion of the screw and having a tip bent toward the screw so as to cover the screw. To be there.

Alternatively, the protection member may be an L-shaped bent so as to cover the screw, and may be a protection plate mounted between the first and second side plates and the flange.

Further, a protection member is provided for preventing the protrusion of the screw into the base 4 and the contact with the heat insulating member 5. In the case of this embodiment, a protective piece 2a1 is provided as the protective member, extending from the flange 2a of the first side plate 2 to the upper part of the screw and bending the tip to the screw side so as to cover the screw. I have. Although not shown because it is the same as FIG. 5, a protective piece extending from the flange 3 a of the second side plate 3 to the upper part of the screw and bending the tip to the screw side so as to cover the screw is provided. (Not shown).

Next, the operation according to another embodiment of the present invention,
The effect will be described. Protective piece 2 as the protective member
Since a1 is provided, the heat insulating member 5 can be mounted without being damaged by the screw.

FIG. 6 is an enlarged sectional view of a main part of a casing of a ceiling-mounted air conditioner showing another embodiment of the present invention. In the case of this embodiment, as the protection member, the first side plate 2 and the second side plate 3 are bent in an L shape so as to cover the screws.
And a protection plate 6 mounted between the flanges 2a and 3a. This attachment is performed by spot welding.

Next, the operation according to another embodiment of the present invention,
The effect will be described. Since the protection plate 6 is provided as the protection member, the heat insulation member 5 can be mounted without being damaged by the screw.
