DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a compressor supporting device used for a refrigerator or an air conditioner.

[0002]

2. Description of the Related Art In compressors used in conventional refrigerators and air conditioners, the vibration caused by the operation of a compression unit during operation is enlarged through connection pipes of the compressor, and noise is reduced. appear. Therefore, for example, as shown in FIG.
A support 5 made of an elastic material such as rubber is attached to a plurality of mounting legs 2 provided around a lower portion of the base 3. The support 5 is passed through a bolt 4 erected on a base 3, and a nut is 6, the vibration of the compressor 1 is suppressed by using a supporting device.

FIG. 4 shows an example of a conventional supporting device, in which the vibration of the compressor 1 is absorbed by a supporting member 5A made of an elastic material such as rubber and having a hollow inside. However, this type is generally used for a small compressor having less vibration, and the vibration damping effect is limited for a large compressor. In particular, the compressor inverter method to change the rotational speed over a wide range, there is a problem that cope with the wide rotational speed (frequency).

Therefore, as shown in FIG. 5, a large-sized compressor and an inverter-type compressor are provided with vibration isolating rubbers 5B and 5C on the upper and lower sides, and a metal coil-shaped spring body 7 therebetween. , The vibration of the compressor 1 is absorbed. However, this type has a problem in cost due to an increase in the number of parts and a long time for assembly.

The support device shown in FIG. 6 solves the above-mentioned problem by forming the body (between the mounting leg 2 of the compressor 1 and the base 3) of the support 5D made of an elastic material such as rubber in a bellows shape. Is what I tried.

[0006] However, the conventional compressor supporting device has a vibration damping effect, but cannot sufficiently absorb the vibration. In particular, since the entire bottom surface of the support 5 attached to the base 3 is in contact with the base 3, the vibration of the compressor 1 is easily transmitted to the base 3, and the vibration may not be sufficiently absorbed. Had a certain problem.

[0007]

SUMMARY OF THE INVENTION In the present invention, in view of the above problems, it is difficult to transmit the vibration of the compressor to the base without increasing the cost, without impairing the absorption of the vibration generated during the operation of the compressor. It is an object of the present invention to provide a compressor support device capable of performing the above-mentioned operations.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a plurality of mounting legs provided around a lower portion of a compressor, and a plurality of mounting legs standing on a base opposed to the mounting legs. A compressor support device comprising: a plurality of bolts; a plurality of supports each having an upper portion attached to the mounting leg and passing through the bolt to elastically support the compressor; and a nut attached to an upper portion of the bolt. Is an elastic body having a structure in which a plurality of convex portions are formed on the bottom surface of the support.

The shape of the projection is a radial sector.

[0010] The shape of the projection is hemispherical.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, based on the embodiment of the present invention embodiment will be described with reference to the accompanying documentation. FIG. 1 is a side view (A) showing a mounting state of a compressor according to the present invention, and perspective views (B) and (C) showing mounting legs of the compressor. FIG. 2 is a compressor supporting device according to the present invention. FIG. 3 is a vertical sectional view (A) showing one embodiment of the present invention, a perspective view (B) of a main part of the support, and a view (C) viewed from the arrow a shown in (B). FIG. (A) of a main part perspective view showing another shape, and a shown in (A).
It is an arrow view (B). The same parts as those in the conventional example are denoted by the same reference numerals.

In the figure, 1 is a compressor, 2 is the compressor 1
Mounting bolts 3 are provided on the base 3 at a predetermined position on the base 3 with respect to the mounting feet 2;
And a support 6 for elastically supporting the compressor 1, and a nut 6 attached to the tip of the bolt 4. Wherein as the distal end portion of the mounting leg 2 shown in FIG. 1 (B), the support 5 the necessary mounting hole 2a for attaching, or 1
