Problems solved by technology
During the working process of the compressor, the eccentric excitation generated by the reciprocating motion of the internal piston and the suction and discharge process of the refrigerant will cause vibration and noise of the compressor body
At the same time, the vibration energy of the compressor body will be transmitted to the high and low pressure connecting pipes connected to it, causing further noise radiation, so the vibration noise of the compressor and pipeline is a complex system problem

Abstract
The invention discloses a vibration and noise reduction device, which is used for a compressor in an electric appliance, and comprises a casing and a buffer liquid. The casing is fixedly arranged on the top of the compressor, and an inner chamber is arranged therein. The buffer solution is filled in the inner cavity, and its volume is smaller than the volume of the inner cavity. When the compressor operates to generate vibration, the buffer fluid is vibrated in the inner cavity to generate relative motion, and part of the vibration energy of the compressor is converted into the flow kinetic energy and internal energy of the buffer fluid, thereby reducing the size of the compressor and the connecting pipe with the compressor. vibration, to achieve the purpose of reducing the noise generated by the compressor. The invention also provides a refrigerator.
Description
technical field [0001] The present invention relates to the technical field of household appliances, more specifically, to a vibration and noise reduction device, and also to a refrigerator. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to the level of home environment, and low-noise household appliances will undoubtedly win the favor of more and more customers. In order to solve the noise problem, many noise reduction methods and means are constantly being applied to home appliances. [0003] For refrigerators, the compressor is the main source of noise. During the working process of the compressor, the eccentric excitation generated by the reciprocating motion of the internal piston and the suction and discharge process of the refrigerant will cause vibration and noise of the compressor body. At the same time, the vibration energy of the compressor body will be transmitted to the high and low pressure ...
