DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-wall type air conditioner, and more particularly to an improvement in the structure of an air conditioner body.

[0002]

2. Description of the Related Art A commonly used air conditioner has an indoor unit mounted at a high position on a wall surface of a room to be air-conditioned, an outdoor unit arranged in an outdoor part of a house, and the indoor unit and the outdoor unit connected via piping and wiring. Connected.

An air conditioner having such a configuration is advantageous for mounting an indoor unit in an existing room to be air-conditioned, but tends to give a sense of oppression when the indoor unit projects into the room. Therefore, it is possible to provide an indoor unit of a wall-embedded type to a user who prefers not to have a feeling of pressure when installed, not to mention a newly built room to be air-conditioned, even in an existing case. I have.

[0004] Specifically, an opening is provided in the wall surface of the room to be air-conditioned, and an installation frame is fitted into the opening, and an air conditioner body in which a heat exchanger, a blower and the like are housed and arranged is mounted and fixed to the installation frame. Then, the opening of the wall surface is covered with the front grill.

[0005] In the room to be air-conditioned, only the front grill is exposed, and there is no protrusion, so that no feeling of oppression is given. By adopting a material, color, and design for the front grille that match the wall and atmosphere of the room to be air-conditioned, there is an advantage that the appearance of the room to be air-conditioned can be improved.

A conventional air conditioner body is shown in FIG.
It is configured as shown in FIG. FIG. 1 is an exploded view for explaining the assembly structure of the air conditioner main body, and the completed main body 1 is a housing having an open front surface.

That is, the main body 1 includes a rear plate 2 which is bent substantially in a U-shape in a side view, and a pair of side plates 3 and 3 which are attached to both side ends of the rear plate and close both side openings. Consists of

In addition, along the upper and lower edges of each side plate 3,
a and 3a are bent, and a mounting hole 4 is formed therein. The pieces 3a of these side plates 3 are fitted to the upper and lower ends of the rear plate 2. Screw holes 5 are provided at positions corresponding to the mounting holes 4, and fixing screws 6 are screwed into these holes, and the side plates 3, 3 are mounted and fixed to the rear plate 2.

A pair of fixing plates 7, 7 are attached and fixed to the inside of the rear plate 2 at a predetermined distance from both side ends. That is, each fixing plate 7 is attached and fixed to the rear plate 2 using, for example, spot welding means before each side plate 3 is attached and fixed to the rear plate 2.

A motor mounting plate 8 is provided on one of the fixed plates 7 (right side in the figure). The motor mounting plate 8 extends from the inner edge of the fixed plate 7 in the direction of the side plate 3 and is bent to the rear side in a range where the motor mounting plate 8 does not contact the fixed plate 7. It is fixed to the part.

The motor mounting plate 8 supports a motor 10 constituting a blower 9. One end of a cross flow fan 11 constituting the blower 9 is supported on a rotating shaft of the motor 10 via a bearing (not shown). The other end of the cross flow fan 11 is supported by a bearing 12 provided on the other fixed plate 7.

Further, the front edge of each fixing plate 7 has only its upper part obliquely inclined, and has a flange portion 7a which is bent inward from each other. End plates 13a provided along both side ends of the heat exchanger 13 are superimposed on these flange portions 7a, and are attached and fixed by fixing screws (not shown).

Therefore, in the assembled state, the air conditioner main body 1 has an opening formed on the front surface, the heat exchanger 13 is disposed inside the main body to face the opening, and the cross flow fan 11 is located on the rear side. Will be done.

A cover 14 is attached and fixed via fixing screws 6 to the front opening of the main body facing one side of the heat exchanger 13. The cover 14 has a certain width in the width direction of the main body 1, and fixing screws 6 are inserted into upper and lower ends thereof, and are attached and fixed to the upper and lower pieces 2 a of the rear plate 2.

Further, the cover 14 also protrudes in the rear direction. The edge has a long protruding length at the upper end, a gradually protruding length gradually inclining toward the lower end, and is inclined along the edge. The piece 14a is bent.

The inclined portion 14a is superimposed on the bent flange portion 7a of the fixing plate 7, and is fixed together with the end plate 13a of the heat exchanger 13. Therefore, the cover 14 protects the U-turn bend exposed on the side of the heat exchanger 13 and also serves as a guide plate for sucking and guiding the air-conditioned room air to the heat exchanger 13 with the heat exchange action. .

[0017]

Since the air conditioner main body 1 is constructed as described above, the air conditioning in the room to be air-conditioned is, of course, surely performed. However, there is a disadvantage that workability is poor due to inferiority.

That is, not only is the main body 1 constructed by assembling the rear plate 2 and both side plates 3 and 3, but also the two fixing plates 7, 7 and the cover 14 are required. There are many.

Each of these components is manufactured and processed in advance.
Considering a series of steps of managing and transporting and attaching to an assembly site, the influence on the cost is extremely large, and therefore it is demanded to reduce the number of parts as much as possible.

Then, a large number of fixing screws 6 required for assembly must be prepared. For example, when the side plate 3 is mounted on the rear plate 2, the mounting operation from the upper side to the lower side and the mounting operation from the lower side to the upper side are performed. Installation work is required. On the other hand, attaching the cover 14 to the rear plate 2 is an attaching operation from the near side to the back side.

As described above, since the mounting direction of the fixing screw 6 is multi-directional, the operator must change the working position each time, and the workability is poor. The present invention has been made with a focus on the above circumstances, and aims at reducing the number of parts and contributing to cost reduction, and at the same time, improving the workability by reducing the work target surface. To provide an embedded wall type air conditioner.

[0022]

According to the present invention, there is provided an air conditioner having a heat exchanger, a blower and the like housed and arranged in an opening provided on a wall surface of a room to be air-conditioned. The air conditioner main body comprises a housing having an opening only at the front surface, a substantially U-shaped rear plate portion in a side view, and at least one side portion of the rear plate portion. And a side plate for closing the heat exchanger. The side plate supports one end of the heat exchanger. The side plate is provided with bearing means for the blower.

[0023]

[Function] Since at least one side plate of the air conditioner body is integrated with the rear plate to support the side end of the heat exchanger, the number of parts is reduced, and the fixing screw and screwing work corresponding to the number of parts are reduced. It becomes unnecessary.

[0024]

An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 2, for example, a Japanese-style room is assumed as the room to be air-conditioned R, and a wall-mounted air conditioner is provided at a high position on the wall surface. To be more specific, only the front grill 20 is exposed to the air-conditioned room R of the air conditioner, and all other components are housed in the space in the wall as described later.

As shown in FIG. 1, an air conditioner main body 1A is configured. The rear plate 23 is formed in a substantially U-shape when viewed from the side, a side plate 24 that is provided integrally with the rear plate in advance at one end of the rear plate, and attached to the other end. And a fixed side plate 25.

The rear plate 23 has a piece 23a which is bent along the upper and lower edges of the front surface. The side plate 24
The other edge portion except the front edge is integrally provided on the rear plate portion 23.

The side plate portion 24 has a one-piece portion 2 integral with the lower piece portion 23a of the rear plate portion 23 from a lower end portion to a substantially middle portion.
4a is provided. A cut is made in the rear direction from the upper end of the piece portion 24a, and a flange portion 24b that is inclined obliquely from the upper end portion is provided integrally.

That is, the side plate portion 24 has a long upper portion and a short opening substantially at the middle portion.
Here, the flange portion 24b is provided with insertion holes 26, 26 composed of a pair of square holes.

A claw portion 27a provided on a cover 27 described later is inserted into these insertion holes 26, and the cover is fixed to the side plate portion 24. That is, the cover 27 has a shape and size that fills the opening portion of the side plate portion 24, the upper end portion abuts on the side edge of the rear plate portion 23, the back side edge abuts on the flange portion 24 b of the side plate portion 24, The lower edge contacts the cut edge of the side plate portion 24.

On the other hand, the side plate 25 for closing the opening on the other side of the rear plate portion 23 may have the same dimensions and shape as the conventional one, but instead of the conventional screwing and fixing, the bent piece portion 25 is used.
It is desirable that the a, 25a and the rear plate portion 23 be integrated by means of spot welding or the like to improve assembly workability.

The fixing plate 7 attached to and fixed to the inner portion of the side plate 25 and the motor attaching plate 8 provided here have the same shape and structure as those of the related art, and are attached and fixed by the same means.

A motor 10 constituting a blower 9 is supported on the motor mounting plate 8, and one end of a transverse fan 11 constituting the blower is supported on a rotating shaft of the motor via a bearing (not shown). The same is true for

The other end of the cross flow fan 11 is pivotally supported by a bearing member 12 which is a bearing means provided on the side plate portion 24 described above. Since the side plate portion 24 is integrated with the rear plate portion 23 and forms the side portion of the main body 1A, there is no displacement of the bearing member 12 due to the assembling work, and the dimensional accuracy of the shaft center is improved. I do.

Then, both end plates 13a, 1a of the heat exchanger 13
3a is superimposed on flange portions 24b and 7a formed on the side plate portion 24 and the fixing plate 7, and is attached and fixed by fixing screws (not shown).

Therefore, in the assembled state, the air conditioner main body 1A has an opening formed on the front surface, the heat exchanger 13 is disposed inside the main body to face the opening, and the cross flow fan 11 is located on the rear side. The basic configuration is the same as the conventional one.

The cover 27 not only protects the U-turn bend exposed at the side end of the heat exchanger 13 but also functions as a heat exchange air suction guide.

Since the air conditioner main body 1A is configured as described above, the one fixing plate 7 which has been conventionally required is no longer required this time, and the number of parts can be reduced accordingly. Then, since the side plate portion 24, which is one side portion, is integrated with the rear plate portion 23, the fixing screw 6 and the work of attaching the fixing screw 6, which are conventionally required, are not required.

Further, in the above embodiment, the side plate portion 24 is provided integrally with the rear plate portion 23 in advance. However, each of the side plate portions 24 may be formed as a separate component and integrated by means such as spot welding. The present invention can be variously modified without departing from the gist thereof.

[0039]

As described above, according to the present invention, the rear plate constituting the main body of the air conditioner and the side plate which is at least one side are integrated, and the side plate is used for the heat exchanger. Since one side end is supported, it is possible to reduce the number of parts and contribute to cost reduction, and to achieve an effect of improving the workability by reducing the work surface.
