Along with the increasing living standard of people and the requirement on the living quality. People also have higher and higher requirements on noise of household appliances and refrigerators, and a compressor is a key motion core part of the refrigerator and is a main generation source of the noise. The silent compressor is an important research subject of various large compressor manufacturers at present. The core reason for generating noise is vibration, so that the design of good vibration reduction parts and vibration reduction systems is important for reducing the noise of the compressor.

The internal vibration reduction system of the existing compressor is composed of an upper supporting block, a pressure spring and a pressure spring supporting block, the whole machine core is placed on the pressure spring through the upper supporting block, and the pressure spring is fixed through the supporting block. The vibration generated by the movement of the compressor core is mainly damped by a pressure spring, and a fixed supporting block and a shell are used for assisting in reducing the vibration.

For example, in 2019, a Chinese utility model patent (publication number: CN208749506U) discloses a vibration reduction supporting structure of a compressor movement and a compressor, which comprises a stator screw, a screw cap, a supporting plate, a damping sleeve, a supporting block and a pressure spring; one end of the stator screw in the preset direction is configured to be connected with a stator of the compressor movement; the surface of the supporting plate is convexly provided with an inner supporting pin along the preset direction; the damping sleeve is sleeved on the inner supporting pin; the inner wall of the supporting block is provided with an embedded cavity, one end of the supporting block, which is close to the supporting plate, is open, the supporting block is sleeved on the circumferential surface of the damping sleeve, and a gap is formed between the supporting block and the screw cap in the preset direction; the compression spring extends along a preset direction, and two ends of the compression spring along the preset direction are respectively sleeved on the screw cap and the supporting block; although the vibration reduction supporting structure of the compressor movement can solve the problems of vibration and noise generation caused by vibration between the existing compressor movement and the supporting structure on a certain length, the vibration attenuation is limited, and the noise exists at any time.
