Problems solved by technology
[0014] However, in the conventional hermetic rotary compressor as described above, although the damping members 22 installed on the three corners of the triangular bottom plate 21, the vibration generated when the compressor is driven has a certain degree of vibration. weakening of
But it does not take into account that the residual torque of the compression torque and the motor torque will cause the vibration of the liquid storage tank 17 and the S-pipe 18 along the tangential direction of the compressor rotation, so it cannot effectively reduce the overall compressor Vibration, this is the problem existing in the prior art

Embodiment Construction
[0031] Hereinafter, the hermetic rotary compressor of the present invention having the above-mentioned structure will be further described in detail with reference to the examples shown in the accompanying drawings.
[0032] Such as Figure 4 As shown, the airtight container 101 of the compressor is equipped with a liquid storage tank 102 for separating liquid refrigerant, and the upper end of the liquid storage tank 102 is connected with an S-pipe 103, through which the circulating refrigerant gas can be delivered to the liquid storage tank 102.
[0033] In addition, a triangular bottom plate 104 is connected to the bottom of the above-mentioned airtight container 101, and the three corners of the above-mentioned triangular bottom plate 104 are respectively equipped with shock absorbing components: 101 ′, 101 ″, 101 ″′. Compared with the rest of the shock absorbing parts 101 ″, 101 ″, the shock absorbing part 101 ′ in the diagonal direction of the tank 102 and the S-pipe 103...

The sealed rotary compressor includes sealed container of the compressor, liquid storage and S-shaped pipe connected to outside of the container and triangular base plate connected to the bottom of the container, and the triangular base plate is fixed to the pedestal of the refrigerator unit and has three damping units under its three corners. The present invention features that the three damping units under the triangular base plate are made of material with hardness higher than that of the material for the other damping units. The said structure can reduce the vibration of the liquid storage and the S-shaped pipe in tangent direction during the compressor operation and lower the noise of the compressor obviously.
Description
technical field [0001] The invention relates to a hermetic rotary compressor, in particular to its damping structure. Background technique [0002] Hermetic rotary compressors are generally used in refrigeration cycle devices of electrical equipment such as air conditioners, and are used to compress refrigerants. It is structured like figure 1 As shown, a brief description of it is given below. [0003] As shown in the figure, in the existing hermetic rotary compressor, the interior of the airtight container 1 is equipped with an electric structural part 4 composed of a rotor 2 and a stator 3, and the center of the rotor 3 forms a shaft hole 2a along the vertical direction. Rotating shaft 5 is pressed in and fixed in the shaft hole. [0004] In addition, an eccentric portion 6 is formed integrally with the lower end of the rotary shaft 5 , and a rolling piston 7 is inserted outside the eccentric portion 6 . In addition, a compression structure part 12 is installed, and t...
