Abstract

The invention discloses a compressor and refrigeration equipment. The compressor comprises a shell and a sound insulation structure, wherein the shell is provided with an inner cavity; the sound insulation structure is arranged in the inner cavity; the sound insulation structure is provided with a hollow channel extending in the axial direction of the shell; a plurality of cavities communicating with the channel are formed in the inner wall of the channel at intervals; the width of the cavities is gradually reduced or increased in the radial direction of the shell and away from the channel, so that the width of the cavities is non-uniformly distributed; and when sound waves enter the cavities, the sound waves can be reflected in the cavities, so that the sound insulation effect is achieved, the noise of the low-frequency band is effectively reduced, the noise reduction effect is good, and the noise reduction problem of a narrow space in the compressor can be effectively solved through the sound insulation structure.

Description

technical field [0001] The invention relates to the technical field related to electrical appliances, in particular to a compressor and refrigeration equipment. Background technique [0002] In related technologies, low-frequency sound waves have strong penetrating power and are difficult to attenuate. Generally, large-mass and large-size structures are required to attenuate them. Especially for noise reduction of compressors, it is often difficult to solve in practical applications. The problem of spatial noise reduction. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a compressor, which can play a role of sound insulation for sound waves in the middle and low frequency bands, and has a good noise reduction effect. [0004] The present invention also provides a refrigeration device including the above-mentioned compressor. [0005] T...
