Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a compressor having a soundproof material, and its object is to enhance the soundproof effect of the soundproof material.

[0002]

2. Description of the Related Art In the conventional soundproofing of a compressor for sucking in and compressing and discharging a fluid, for example, a refrigerant compressor used in an air conditioner, a sheet of soundproof material such as glass wool is wound around a housing of the compressor.

[0003]

However, with this structure, it is not possible to completely prevent the sound from surrounding the housing without a gap, and the noise of the compressor leaks from this gap, resulting in a sufficiently high sound-insulating effect. I couldn't make it into a state.

The present invention provides a method of manufacturing a compressor that solves the above-mentioned conventional problems, and manufactures a compressor excellent in sound insulation and sound insulation.

[0005]

In order to solve the above-mentioned problems, the present invention provides a compressor having a mechanism part inside and a hermetic housing having a suction pipe and a discharge pipe, a leg of the compressor, and a suction port. Has holes or notches through which the pipe and discharge pipe protrude,
It is provided in a case that can be divided into a plurality of parts, and a space made up of a closed housing and a case is filled with a soundproof material and then the case is removed.

[0006]

Since the soundproofing material can be integrally formed around the closed housing by the above method, the noise of the compressor is not leaked from the gap between the closed housing and the soundproofing material as in the conventional case. Further, since the soundproof material and the hermetically sealed housing are integrated with each other, there is no relative movement between them, and noise generated by this relative movement can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A compressor manufacturing method according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a perspective view of the compressor, and FIGS. 2 and 3 show manufacturing process diagrams thereof. In the figure, reference numeral 1 denotes a refrigerant compressor, which sucks refrigerant through a suction pipe 2 provided with an accumulator 3 in the middle thereof, compresses and discharges it by a mechanism section (not shown) provided inside, and a hermetically sealed housing enclosing the mechanism section. The fluid compressed from 5 is discharged through the discharge pipe 6. The compressor 1 integrally surrounds a hermetically sealed housing 5 with a foamed soundproof material 7. A method of integrally foaming the soundproof material 7 on the housing 5 will be described below. In the figure, 8 is an upper case, 9 is a lower case,
The upper case 8 is provided with holes 10 and 11 through which the suction pipe 2 and the discharge pipe 6 pass, respectively, and an injection hole 12 for foaming a soundproof material, and the lower case 9 is provided with a leg 13 of the compressor 1 below. A notch 14 is provided so as to extend outside the case 9, and the upper case 8 and the lower case 9 are aligned so as to surround the compressor 1 as shown in FIG. It is injected and foamed in the space surrounded by the compressor 1, the upper case 8 and the lower case 9, and after the soundproof material is surrounded, the upper case 8 and the lower case 9 are removed. The leg 13 is the compressor 1
Is fixed to a base (not shown) of the main body of the air conditioner, for example, and it is necessary to project the foamed soundproof material 7 to the outside. By thus integrally foaming the soundproof material 7 so as to surround the entire housing 5 of the compressor 1, it is possible to prevent noise from leaking from the housing 5. Further, since the soundproof material 7 is integrated with the housing 5, the vibration of the compressor 1 prevents the housing 5 and the soundproof material 7 from contacting each other and causing relative movement to generate noise. Further, by providing the accumulator 3 inside the foamed soundproofing material 7 as shown in FIG. 1, the accumulator 3 can be thermally insulated, which improves the efficiency of the compressor 1 and reduces the noise from the accumulator 3. Can be shielded.

Although the above embodiments have been described with reference to the refrigerant compressor, it is obvious that the invention can be applied to a compressor for fluid other than the refrigerant.

[0009]

As is apparent from the above description, the method of manufacturing a compressor according to the present invention includes a hermetic housing having a suction pipe and a discharge pipe, the suction pipe and the discharge pipe provided in the hermetic housing. A compressor composed of a mechanism for inhaling / compressing / discharging the communicating fluid is provided in a case that can be divided into a plurality of parts, and the legs of the compressor, the suction pipe, and the discharge pipe are provided in the case. A hole or notch is provided in the case so as to project to the outside, a space made up of the closed housing and the case is filled with a soundproofing material, and then the case is removed. methods and in fire acoustic insulation around the hermetic housing can be an integral structure, the conventional sealed housing as compressor noise leaks from the gap between sound insulation, the sound insulation effect is reduced Since the soundproof material and the hermetically sealed housing are integrated, there is no relative movement between them, and there is no noise generated by this relative movement. A compressor with excellent sound insulation and sound insulation is manufactured. be able to. Further, in the method of manufacturing a compressor of the present invention, the time and effort of sticking the soundproofing material by adhesion or the like is not necessary, and variations in the manufacturing due to this sticking do not cause the compressor noise value to be high or low, and the stable quality is maintained. A compressor can be provided. Moreover, the application
As in the invention, the leg is projected from the cutout portion of the case.
The method of injecting the soundproofing material is as follows:
This is extremely effective for setting the
From the point of view also, it is a stable product that eliminates the thickness variation of the soundproof
Can provide quality compressor.
