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. This 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 housing.

3 is a support leg of a hermetic electric compressor having a mounting hole smaller in diameter than the outer diameter of the flange 2a of the buffer body 2; 4 is a support leg of the buffer body 2;
It is a sleeve that is inserted into the insertion hole of the support leg 3, and when assembling, the collar 2a of the buffer body 2 is first deformed and the support leg 3 is inserted into the support leg 3.
After screwing the sleeve 4 into the mounting hole and engaging the peripheral edge of the mounting hole with the annular groove, the sleeve 4 is inserted into the insertion hole and placed on the support stand 1, and the washer 5 is inserted from above.
The compressor was fixedly supported on the support base 1 using bolts 6 inserted through the compressor, but this not only required a large number of parts but also increased the number of man-hours.Furthermore, since hermetic electric compressors are usually supported at four locations, the work efficiency was reduced. It had a very bad flaw.

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; The shock absorber 3 is made of synthetic resin and has mounting holes for supporting legs of the hermetic electric compressor.

The buffer body 7 includes a cylindrical main body 8, and a plurality of notches 9a, 9a and 10a, 10a on the outer periphery of both upper and lower ends of the main body, which protrude elastically in the direction of the center line of the main body 8. upper and lower locking claws 9.9 and 10.10;
.
A 0-shaped groove 13 opening at the end in one or both of the upper and lower parts,
13 is formed.

The upper and lower locking claws 9, 9 and 10.10 are connected to the main body 8.
The degree of protrusion thereof is increased in a tapered shape from both upper and lower ends toward the upper and lower flanges 11 and 12.

Next, to explain the assembly, fit the upper part of the main body 8 of the buffer body 7 into the mounting hole of the support leg 3 while pressing the upper body retaining claws 9, 9 in the direction of the center line. The periphery of the mounting hole of the support leg 3 is held between the flange 12 and the lower part of the main body 8 of the shock absorber 7 is placed in the mounting hole of the support base 1 in the same way with the progeny retaining claws 10, 10 and the lower flange 12. It is fixedly supported by pinching the periphery of the first mounting hole.

The order of assembling the support legs 3, support stand 1, and buffer body 7 is as follows:
Although it has been explained that the support leg 3 side is assembled and then the support stand 1 side is assembled, this assembly order may be either the support leg 3 side or the support stand 1 side first, and the buffer body 7 may not be upside down. It's okay to be.

Further, the case of removing the buffer body 7 will be explained based on FIG. 4. Using a clamping tool 14 such as pliers, the end of the buffer body 7 on the side where the U-shaped groove 13 is formed is closed until the opening of the U-shaped groove 13 is closed. The fitting and clamping is released by pressing the support base 1 in the direction shown in FIG.

As mentioned above, the support device for the hermetic electric compressor according to the present invention is as follows:
A hermetic electric compressor having a mounting hole in a support leg, a support stand having an attachment hole for fixedly supporting the hermetic electric compressor, and a buffer interposed between the hermetic electric compressor and the support stand. The shock absorber consists of 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 a gap in the middle of the main body in the direction of the upper and lower locking claws. upper and lower flanges that are inclined or curved, respectively, are formed integrally with each other, and grooves that open at the ends are formed in one or both of the upper and lower parts of the main body, and the mounting hole of the support leg is provided with a groove for attaching the shock absorber to the mounting hole of the support leg. The upper part of the main body is inserted to sandwich the support leg between the upper body stopper and the upper flange, and the lower part of the main body of the shock absorber is fitted into the mounting hole of the support base to connect the progeny stopper and the lower flange. Since the support stand is sandwiched between the parts, vibrations during operation of the hermetic electric compressor can be absorbed by the flexure of the upper and lower brim parts of the shock absorber, which utilizes the characteristics of synthetic resin. By molding the body from synthetic resin, it has higher strength compared to rubber materials, which eliminates the need for reinforcing members, reduces the number of parts, and also improves work efficiency because assembly is simple, just fitting. Furthermore, if it becomes necessary to remove the fixed support of the hermetic electric compressor due to repairs, etc., even if the shock absorber is made of hard synthetic resin, use the opening groove at the end of the shock absorber to remove it with pliers, etc. The fitting and clamping can be easily released using a general clamping tool.
