Problems solved by technology

[0003] The suction noise of the refrigerator compressor is an important source of the noise of the whole machine. The inventor believes that the main structure of the existing compressor suction muffler is composed of the upper and lower shells and the inner tube. Large, easy to loose, poor sealing, large leakage
The existing compressor suction muffler has a small number of chambers and a narrow noise reduction frequency band. It cannot take into account both low frequency and high frequency noise, and the noise reduction effect is poor.

Abstract

The invention discloses a compressor five-cavity air suction muffler and a compressor. The compressor five-cavity air suction muffler comprises a container and a filter screen, wherein the container is provided with an opening; the filter screen is mounted at the opening of a shell; the area of the filter screen is equal to that of the opening; a cavity is formed in the container; a plurality of partition plates are mounted in the container and divide the cavity in the container into a first cavity, a second cavity, a third cavity, a fourth cavity and a fifth cavity which are communicated with each other; and the first cavity is communicated with the opening of the container.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a five-chamber suction muffler for a compressor and a compressor. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The suction noise of the refrigerator compressor is an important source of the noise of the whole machine. The inventor believes that the main structure of the existing compressor suction muffler is composed of upper and lower shells and an inner insertion tube. Large, easy to loose, poor sealing, large leakage. The existing suction muffler for a compressor has a small number of chambers, a narrow noise reduction frequency band, cannot take into account both low-frequency and high-frequency noise, and has a poor noise reduction effect. Contents of the invention [0004] In view of the deficiencies in the prior art, the pu...
