Description

[Detailed description of the invention] This invention relates to a support device for a hermetic electric compressor in a refrigerator, etc., and in particular, an improvement of a vibration-proof support device that prevents vibrations during operation of a hermetic electric compressor from being transmitted to the main body of the refrigerator, etc. It is related to.

A conventional example of this type of seed support device will be explained based on Fig. 1.
1 is a support stand for a hermetically sealed electric compressor placed at the bottom of a refrigerator, etc., and 2 is a buffer made of a rubber material to prevent vibrations from being transmitted to the refrigerator's body when operating the hermetically sealed electric compressor. The shock absorber has a collar portion 2a provided with an annular groove and a body portion 2b.
An insertion hole is provided in the center of the holder.

Reference numeral 3 designates a support leg of the hermetic electric compressor, which has a mounting hole smaller in diameter than the outer diameter of the flange 2a of the buffer body 2, and 4 a sleeve that is inserted into the insertion hole of the buffer body 2. First, the flange 2a of the buffer body 2 is deformed and screwed into the mounting hole of the support leg 3 to engage the peripheral edge of the mounting hole with the annular groove, and then the sleeve is inserted into the insertion hole. 4 was inserted into the support base 1, and the washer 5 was inserted into the support base 1 and fixedly supported on the support base 1 using bolts 6 from above. In addition, hermetic electric compressors are usually supported at four points, resulting in extremely poor work efficiency.

This proposal has been made in view of the above points, and will be explained below based on an embodiment shown in FIGS. 2 to 4. 1 is a support stand for a hermetic electric compressor provided with a mounting hole; 7 is a support stand for a hermetic electric compressor; A shock absorber 3 made of synthetic resin is a support leg of a hermetic electric compressor provided with mounting holes.

The buffer body 7 has a cylindrical main body 8 and can be elastically deformed in the direction of the center line of the main body 8 by cutouts 9a, 9a and 9'a, 9'a on the outer periphery of both upper and lower ends of the main body. A plurality of upper and lower locking claws 9.9, 9', 9' that protrude, and the upper and lower locking claws 9 are spaced apart from each other on the outer periphery of the trunk of the main body 8.
, 9 and 9'.

The tapered and suction cup-shaped upper and lower flanges 10 and 10', which are respectively inclined or curved in the 9' direction, are integrated, and the B-B
It is shaped so that the top and bottom are symmetrical with respect to the line.

Further, the upper and lower locking claws 9, 9 and 9', 9' are tapered to increase their protrusion from both upper ends of the main body 8 toward the upper and lower flanges 10 and 10'.

Next, to explain the assembly, the upper or lower part of the main body 8 of the buffer body 7 is inserted into the mounting hole of the support leg 3 while pressing the upper locking claw 9 or descendant locking claw 9' in the direction of the center line, and the upper locking is performed. The periphery of the mounting hole of the support leg 3 is held between the claw 9 or descendant retaining claw 9' and the upper flange 10 or lower flange 10', and then the lower or upper part of the main body 8 of the buffer body 7 is inserted into the mounting hole of the support base 1. The support base 1 is assembled with the descendant locking claw 9' or the upper locking claw 9 and the lower flange 10' or the upper flange 10.
It is fixedly supported by clamping the periphery of the mounting hole.

The order of assembling the support legs 3, the support base 1, and the shock absorber 7 has been explained such that the support leg 3 side is assembled, and then the support base 1 side is assembled, but this assembly order does not matter which one comes first. good.

As mentioned above, the support device for the hermetic electric compressor according to the present invention is as follows:
A hermetic electric compressor having mounting holes in the support legs; a support base having mounting holes for fixedly supporting the hermetic electric compressor; and a synthetic resin material interposed between the hermetic electric compressor and the support base. The buffer body includes a cylindrical main body, upper and lower locking claws protruding from the outer periphery of the upper and lower parts of the main body, and upper and lower locking claws that are spaced apart from each other on the body body. Tapered upper and lower flanges that are inclined or curved in the direction of the claws are integrally molded vertically symmetrically, and the upper or lower body of the buffer body is fitted into the mounting hole of the support leg so that the upper or lower flanges are The support leg is held between the retaining claw and the upper or lower flange, and the lower or upper part of the main body of the shock absorber is inserted into the mounting hole of the waist and the support base, and the lower or upper retaining claw and the lower or upper flange are held together. Since the support base is held between the two parts, the collar part takes advantage of the strong properties of the synthetic resin material and maintains the inclination toward the locking claw, so that only the peripheral edge part of the collar is held. contact with the compressor support leg, reducing the area of vibration transmission from the compressor support leg to the flange, and the periphery of the flange, which has increased elasticity due to its tapered shape, supports the compressor support leg with good cushioning properties and compresses. It can absorb the vibrations of the machine support legs and prevent the vibrations from being transmitted to the cylindrical body of the shock absorber. Therefore, the vibration transmission from the compressor support legs to the entire support base can be effectively transmitted by the upper and lower flanges of the shock absorber. can be prevented.

Moreover, by forming the shock absorber from synthetic resin, not only can the number of parts be reduced, but assembly is as simple as fitting, which improves work efficiency.Furthermore, the top and bottom of the shock absorber are symmetrical, making it easier to assemble. There is no need to distinguish between the top and bottom, further improving work efficiency.
