Description

Compressor damping mechanism and refrigerator Technical Field The invention relates to the technical field of vibration reduction of a refrigerator compressor, in particular to a vibration reduction mechanism of a compressor and a refrigerator. Background The refrigerator is an indispensable electrical equipment of modern families, and the working state of a core component, namely a compressor, directly influences the refrigeration efficiency, the service life and the running noise of the refrigerator. However, the compressor inevitably generates vibrations during operation, and if these vibrations are not effectively controlled, not only the abrasion of mechanical parts of the compressor itself can be accelerated, the service life of the equipment can be shortened, but also noise pollution can be caused by the transmission of the refrigerator box to the surrounding environment, and the use experience of users is affected. Therefore, research and application of the damping technology of the refrigerator compressor are particularly important. Refrigerator compressor vibration mainly comes from unbalanced force, air column resonance, electromagnetic force and the like of internal mechanical moving parts thereof. This vibration energy is continuously generated while the compressor is running and transferred through the compressor block to the refrigerator cabinet and further diffused to the surrounding environment. The long-term vibration not only can lead to looseness and abrasion aggravation of internal parts of the compressor, but also can cause faults such as looseness of a pipeline connection part, refrigerant leakage and the like, and seriously influences the stability and reliability of the refrigerator. In order to solve the vibration problem of the compressor, the traditional method mainly adopts a rigid fixed rubber pad or a simple rubber pad for damping. The rigid fixing tightly connects the compressor with the refrigerator body through the bolts, and although the displacement of the compressor can be limited to a certain extent, the vibration energy cannot be effectively absorbed, and on the contrary, the resonance of the refrigerator body is possibly caused by the vibration transmission, so that the noise problem is aggravated. The simple rubber pad shock attenuation utilizes the elasticity characteristic absorption part vibration energy of rubber, but its shock attenuation effect is restricted by factors such as rubber material, thickness and shape, is difficult to satisfy high accuracy, high stability shock attenuation demand. The vibration of the compressor cannot be completely isolated from the bottom plate by the rubber pad, so that when the compressor runs, the refrigerator integrally gives out noise and vibration, when the running vibration of the compressor exceeds a certain range which can be born by the rubber pad, the vibration is always transmitted to the bottom plate downwards along the rubber pad, the vibration and the noise are further increased, the compressor is used as a rotary machine, the vibration of the compressor not only has linear vibration, but also has torsional vibration, and the rubber pad cannot have good damping effect on the vibration. Therefore, the application provides a compressor vibration reduction mechanism and a refrigerator.
