Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a ceiling-suspended type that is suspended from the lower surface of the ceiling,
This invention relates to a ceiling-embedded air conditioning unit that is embedded in the ceiling.

(b) Conventional technology A hanging air conditioning unit was developed in Japan in which a compressor and a water-cooled condenser are placed on a strong bottom plate, and the load on this bottom plate is supported by a pair of hanging frames. It is presented in Publication No. 47-36814.

(c) Problems that the invention aims to solve The air conditioning unit proposed in the above publication uses a pair of hanging frames assembled in a frame shape, which makes the device large-scale and has the problem of high manufacturing costs. Was. Moreover, since the panel is attached to the outside of the hanging frame from the outside, it is necessary to align the panel and hold the panel by hand during installation, which poses a problem of poor workability. Was.

The present invention provides a hanging air conditioning unit that solves the above-mentioned problems.

(d) Means for solving the problem In this proposal, a support plate whose lower part is fixed to the lower surface of the bottom plate of the unit main body and whose upper part is attached to a hanging fixture is formed from a single sheet metal, and this support plate is A gap is provided between the intermediate portion and the outer surface of the side wall of the bottom plate, into which the lower end of the panel is inserted, and a stopper is provided within this gap, with which the lower edge of the panel abuts.

(e) Function The lower and upper parts of the support plate are bent in the horizontal direction, and a plurality of stoppers are formed in advance by doweling at the left and right parts of the middle part. Then, when the lower part of the support plate is fixed to the lower surface of the bottom plate by welding or the like with the tip of the stopper in contact with the side wall of the bottom plate, a gap is formed between the side wall of the bottom plate and the middle part of the support plate, and this gap After inserting the lower end of the panel from above and bringing the edge of this lower end into contact with the upper end of the footper, the side wall of the bottom plate, the lower end of the panel, and the middle part of the support plate are screwed together. Thereafter, the installation work is completed by attaching the upper part of the support plate to the lower end of the hanging fixture whose upper end is fixed to the ceiling.

(F) Embodiment FIG. 1 is a sectional view of a ceiling-embedded air conditioning unit, in which a bottom plate 2 made of sheet metal having a side wall 1, a panel 3 assembled to this bottom plate, and a top plate 4 are connected to the unit main body 5. An outer casing is formed.

A compressor 6 and a water-cooled condenser 7 are placed on the bottom plate 2, and these devices, as well as a blower (not shown) and an evaporator for cooling room air, are built into the unit body 5.

8 is a ceiling board, 9 is a ceiling beam, and 10 is a hanging tool whose upper end is fixed to the ceiling beam 9 and which has a nut 11 at its lower end.

Reference numeral 12 denotes a support plate made of sheet metal with a lower part 13 and an upper part 14 bent in the horizontal direction, and a plurality of stoppers 16 are formed by doweling in the left-right direction (direction perpendicular to the drawing) of this intermediate part 15. As shown in Fig. 2, the tip 1 of the stopper 16
7 in contact with the side wall 1 of the bottom plate 2.
When the lower part 13 of 2 is fixed to the lower surface of the bottom plate 2 by welding, the outer surface of the side wall 1 of the bottom plate 2 and the intermediate part 15 of the support plate 12
A gap 18 is formed between the two.

Moreover, this gap 18 is set to be somewhat larger than the thickness of the panel 3,
Insert the lower end 19 into the gap 18 from above and insert the edge 20 of the lower end 19 into the upper end 21 of the stopper 16.
When the panel 3 is brought into contact with the side wall 1 of the bottom plate 2, the lower end 19 of the panel 3, and the support plate 1, the panel 3 is positioned.
Since the screw holes drilled in the middle part 15 of the panels 2 and 2 coincide with each other, it is difficult to hold the panel 3 by hand.
2 can be easily screwed together from the outside.

Note that if the stopper 16 is not provided, the support plate 1
When welding 2 to the bottom plate 2, there is a risk that the dimension setting of the gap 18 will be incorrect, and the insertion dimension of the panel 3 is set by bringing the lower edge 20 of the panel 3 into contact with the bent part 23 of the support plate 12. If this is attempted, the curvature of the bent portion 23 is not uniform, so there is a risk that the insertion dimension will be misaligned.

For this reason, the stopper 16 is provided, and the stopper 16 may be provided on the side wall 1 of the bottom plate 2 instead of being provided on the support plate 12.

Also, the side wall 1 of the bottom plate 2 is made higher and the support plate 12
The side wall 1 and the panel 3 may be screwed together at the upper position, but if the hanging tool 10 is fixed diagonally, the support plate 12 attached to the hanging tool 10 with a nut 11. This is not preferable because the upper part 14 of the support plate 12 is pulled outward and the middle part 15 of the support plate 12 tends to open.

(g) Effects of the device The device provides a gap between the support plate for suspending the unit body and the side wall of the bottom plate of the unit body into which the panel is inserted, and also provides a stopper in this gap against which the lower edge of the panel comes into contact. Therefore, when installing the panel, temporary fixing of the panel and positioning of the panel are performed at the same time, and the panel can be easily fixed with screws.

Moreover, since the size of the gap is set by the stopper, there is no need to manage the dimensions when fixing the support plate to the bottom plate, and the work of assembling the support plate can be easily performed.

In addition, by screwing the bottom plate, the panel, and the support plate together, the strength of the support plate can be increased.
