Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to an air conditioner embedded in a ceiling.

(B) Conventional Technology As an example of the installation structure of the air conditioner embedded in the ceiling, the one disclosed in Japanese Utility Model Laid-Open No. 60-118431 is disclosed.

In the air conditioner disclosed in this publication, the attachment piece fixed to the suspender in the ceiling is attached to the outer surface of the main body. Therefore, when mounting the main body on the ceiling, first, an opening having a width dimension larger than the width dimension of the main body including the mounting pieces is formed on the ceiling surface, and the main body is inserted into the ceiling through this opening to remove the internal space of the ceiling. Attach this mounting plate to the hanging equipment. After the main body is embedded in the ceiling in this manner, the openings on the ceiling surface and the main body are covered with panels.

(C) Problems to be solved by the invention In such an air conditioner, since the mounting piece is mounted on the outer surface of the main body, the opening formed in the ceiling surface has a width dimension of the main body including the mounting piece. It was necessary to secure the installation space by making the gap larger between the outer side surface of the main body and the opening on the ceiling surface. For this reason, the panel covering the opening is inevitably large, and as a result, the installation area may be large relative to the size of the main body.

It is an object of the present invention to provide an air conditioner having a small installation area by reducing the gap between the outer surface of the main body and the opening on the ceiling surface.

(D) Means for Solving the Problems In order to achieve this object, the present invention provides a temperature control heat exchanger and a blower so that a working space is formed in the center of the main body. In this work space, a support tool that supports the air conditioner is accommodated by a suspender installed in the ceiling.

(E) Action By removing the decorative panel from the main body, the working space at the center of the main body faces the lower part of the main body, put your hands into this working space, and attach the support to the hanging device while supporting the main body. To be

(F) Embodiment FIG. 4 is an exploded perspective view of the air conditioner 1 embedded in the ceiling, 2 is an outer plate bent in a substantially U shape so that the opening is located downward, and 3 is this outer plate 2. Reinforcing pieces 5 welded to the upper surface 4 of the cross-flow fan 5 arranged along the bent portion 6 of the outer plate, 7 a pair of mounting plates arranged on the left side of the cross-flow fan 5, The flange piece 8 of the attachment plate 7 is attached along the inner surface 9 of the bent portion 6 of the outer plate 2. Left side 10 of this mounting plate 7
An electric motor 11 that drives the cross flow fan 5 is attached to the. Reference numeral 12 is a bearing plate disposed on the right side of the cross flow fan 5, and a flange piece 13 is attached along the inner surface 9 of the bent portion 6 of the outer plate 2. A heat exchanger assembly 14 is a plate fin type heat exchanger (heat exchanger for temperature control) 15 and 16 arranged in a substantially C-shape facing each other. The auxiliary plate 19 is connected, and both heat exchangers 15 and 16 are connected by a single refrigerant pipe. In this way, the assembly 14 can be handled integrally. And each heat exchanger 15,

A left side plate 20 is attached to the left side flange piece 21 of the outer plate 2. Reference numeral 22 denotes an electrical equipment box having an opening on the lower surface, which is arranged between the auxiliary plate 19 and the left side plate 20.
A right side plate 23 is attached to the right side flange piece 24 of the outer plate 2. Reference numeral 25 is a frame-shaped drain pan having a ventilation port 26 formed in the center thereof, and flowing water channels 27 are provided on each of the four sides, and these flowing water channels are connected to one. The drain pan 25 is disposed below the assembly 14 of the heat exchangers 15 and 16, and the lower portion 28 of the left heat exchanger 15 is in the running water channel 29.
The lower part 30 of the right heat exchanger 16 is in the running water channel 31, and the lower part 32 of the right side auxiliary plate 19 connecting both heat exchangers is in the running water channel 33.
Lower parts (not shown) of the left auxiliary plates 34 are respectively located in the running water channels 35. Therefore, the drain water dripping from the left heat exchanger 15 is the running water channel 29, the drain water dripping from the right heat exchanger 16 is the running water passage 31, and the drain water dripping from the left U-tube 35 of both heat exchangers 15 and 16. The water is in the running water channel 33, the drain water dripping from the right U-shaped pipes 36 of the heat exchangers 15 and 16 is received in the running water path 35, respectively, and the received drain water is collected in the running water path 35 of the left short piece. .

Although not shown, the left auxiliary plate 34 is provided with a drain pump so that the drain water collected in the flow passage 35 of the drain pan 25 is sucked up and discharged from the drain pipe.

Reference numeral 38 is a decorative panel having a suction grill 39 in the center and laterally long discharge ports 40 on both sides of the suction grill. The decorative panel 38 is applied to the lower side of the outer plate 2, and when the decorative panel 38 is applied to the outer plate 2 in this way, the heat exchanger 1 having the suction grilles 39 arranged in a V shape.
The discharge port 40 faces the cross flow fan 5, and faces the working space between 5 and 16 (described later). One of the mounting holes 41 adjacent to the discharge port 40 matches the screw hole 43 of the lower flange piece 42 of the mounting plate 7, and the other mounting hole 44.
Coincides with the screw hole 46 of the flange piece 45 of the bearing plate 12. Then, the decorative panel 38 is attached to the outer plate 2 with screws.

In such an air conditioner 1, the cross flow fan 5
The room air is introduced into the working space between the heat exchangers 15, 16 facing each other in a V-shape through the suction grill 39 by rotating the. The air introduced into this space is divided into the two heat exchangers 15 and 16 and exchanges heat with the refrigerant flowing in the heat exchangers, and is blown out from the respective discharge ports 40.
