Abstract

PURPOSE:To reduce noises, which are generated during operation of an outdoor unit for an air conditioner, by covering an accumulator with a noise insulating material. CONSTITUTION:In the case of operation of an air conditioner, namely, a compressor 3, noises such as a vibration noise and a refrigerant circulation noise are generated from an accumulator 2. However, these noises are insulated and absorbed by a noise insulating material 1 covering the accumulator 2. The noise insulating material 1 is made of a sewed matter according to the shape of the accumulator 2, whereby the enclosing properties of the noise insulating material 1 are increased to make a noise-proof effect greater. By this method, a noise-proof effect of the accumulator 2 can be hightened, and noises of the air conditioner, which are generated during operation of its outdoor unit, can be reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor unit of a separate type air conditioner.

[0002]

2. Description of the Related Art In an outdoor unit of a conventional separate type air conditioner, an accumulator 7 is installed near a compressor 8 as shown in FIG. Are covered by
The soundproof material 9 had functions of preventing noise from the accumulator 7 and the compressor 8, buffering the surrounding structures, and preventing freezing of the accumulator 7.

[0003]

However, when the layout of the compressor, accumulator, etc. is changed in order to make the outdoor unit compact, it is difficult to prevent noise such as vibration noise and refrigerant circulation noise from the accumulator. Met.

Further, due to the complexity of the shape of the accumulator, it has been difficult to improve the degree of sealing by the soundproof material.

Furthermore, due to the complexity of the shape of the accumulator, it is difficult to adhere and fix the soundproof material.

[0006]

The technical means of the present invention for solving the above-mentioned problems is to cover a single accumulator with a soundproof material.

Further, according to the present invention, the accumulator unit is covered with a soundproof material sewn according to the shape of the accumulator.

Further, according to the present invention, the soundproof material is brought into close contact with the accumulator by a fixture.

[0009]

The operation of the above technical means is as follows.

That is, by covering the accumulator alone with the soundproof material, the side portion of the accumulator is sealed, the soundproof effect can be enhanced, and the cushioning effect to the surrounding structures can be realized.

Further, according to the present invention, by covering with a soundproof material sewn in conformity with the shape of the accumulator, the degree of sealing of the accumulator can be improved and the soundproof effect can be enhanced.

Further, according to the present invention, the soundproof material sewn in conformity with the shape of the accumulator is brought into close contact with the fixing tool, thereby further improving the airtightness of the accumulator and further improving the soundproofing effect, and saving the accumulator portion. Space can be further reduced, and the outdoor unit of the air conditioner can be downsized.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the inside of an outdoor unit, and 1 is a soundproof material that covers an accumulator 2 incorporated in the outdoor unit. The entire configuration showing the present embodiment is shown in FIG. 2, and comprises an accumulator 2, a compressor 3, a heat exchanger 4, a blower 5 and the like.

In the above structure, when the air conditioner is operated, that is, when the compressor 3 is operated, the accumulator 2 produces noise such as vibration noise and refrigerant circulation noise.
Noise during operation of the air conditioner is reduced by the sound insulation and sound absorption effects of the soundproof material 1 covering the accumulator 2.

Furthermore, when the main body is dropped, the impact of the accumulator 2 and surrounding structures can be alleviated by the cushioning effect of the soundproof material.

Next, a second embodiment of the present invention will be described with reference to FIG. The soundproof material 1 shown in the figure is sewn in conformity with the shape of the accumulator 2, whereby the soundproof material 1 is highly sealed and the soundproof effect is further enhanced. Furthermore, due to the heat insulation effect of the soundproof material 1,
It is possible to prevent freezing of the accumulator 2 during heating operation.

Further, referring to FIG. 4, a third embodiment of the present invention will be described. The soundproof material 1 shown in the figure is in close contact with the accumulator by the fixture 6, which further enhances the hermeticity of the soundproof material 1 and enhances the soundproof effect. Further, since the accumulator 2 and the soundproof material 1 are in close contact with each other, the space occupied by the soundproof material 1 is reduced, and the space of the accumulator portion can be saved.

[0018]

As is apparent from the above embodiment, the present invention can enhance the soundproof effect of the accumulator by covering the accumulator with the soundproof material in the outdoor unit of the air conditioner, and the outdoor unit of the air conditioner can be enhanced. Noise during operation can be reduced. Furthermore, when a shock is applied during transportation or when the main body is dropped, the shock to the accumulator and surrounding structures can be mitigated, and defects such as dents or failures can be prevented.

Further, by covering the accumulator unit with a soundproof material sewn in conformity with the shape of the accumulator, the soundproof effect can be enhanced by improving the airtightness of the soundproof material. Furthermore, due to the heat insulating effect of the soundproof material, it is possible to prevent the growth of ice due to the freezing of the accumulator during the heating operation.

Further, the soundproof material is brought into close contact with the accumulator by the fixing tool, whereby the degree of sealing of the soundproof material is further improved and the soundproof effect can be further enhanced. Further, the space between the accumulator housing portion can be saved by the close contact between the accumulator and the soundproof material.
