Description

Technical Field

[0001] The utility model relates to the technical field of vibration reduction of refrigerator compressors, in particular to a vibration reduction structure of a refrigerator compressor. Background Art

[0002] The vibration reduction structure of refrigerator compressor is usually designed to reduce the vibration and noise generated when the compressor is running, so as to improve the stability and comfort of the refrigerator. Common vibration reduction structures include:

[0003] Shock-absorbing pads: Shock-absorbing pads are installed at the bottom of the refrigerator or the bottom of the compressor. They are usually made of rubber or spring materials and can absorb vibrations and reduce noise transmission.

[0004] Vibration isolation brackets: Install vibration isolation brackets or vibration isolation feet around the compressor to reduce direct contact with the surrounding structure and reduce the transmission of vibration to the bottom or other parts of the refrigerator.

[0005] Vibration-damping gaskets: Add vibration-damping gaskets between the compressor and the refrigerator wall or between the compressor and the mounting base to play a buffering and shock-absorbing role and prevent the spread of vibration.

[0006] Vibration isolation cover: The compressor is designed with an outer cover and filled with sound insulation material inside, which can not only isolate vibration but also reduce noise, thereby improving the overall comfort of the refrigerator.

[0007] Elastic connecting pipe: Soft elastic connecting pipes are used on the compressor inlet and outlet pipes, which can absorb the vibration and noise generated when the pipes move and reduce the impact transmitted to the refrigerator.
