Suction silencer for compressor

Abstract

The invention discloses a suction muffler for a compressor. The technical scheme includes that a partition is arranged between an upper shell and a lower shell, an S-shaped pipe component is arranged between the partition and the lower shell, and an air suction pipe located outside the lower shell is connected with the S-shaped pipe component; the partition comprises an air pipe, a support plate and a fixing plate; the support plate is arranged above the lower shell, the fixing plate and the air pipe are arranged inside a shell body of the upper shell, the air pipe is fixed on the support plate, an air outlet of the air pipe is connected with an air outlet pipe of the upper shell, and an air inlet of the air pipe is connected with an exit of the S-shaped pipe component; the fixing plate is vertically arranged on the support plate along the axis direction of a muffler and connected with a pipe body of the air pipe, and the fixing plate divides a space formed by the partition and the shell body of the upper shell into a first muffler chamber and a second muffler chamber; a first expanding hole is formed in a position, where the first muffler chamber is located, of the air pipe, and a second expanding hole is formed in a position, where the second muffler chamber is located, of the air pipe. By adopting four muffler chambers and multiple expanding holes in the S-shaped pipe component, best effect of noise reduction is achieved.

Description

technical field [0001] The invention relates to a refrigeration compressor, in particular to a suction muffler for a compressor. Background technique [0002] With the improvement of people's quality of life, miniaturized refrigerators, freezers, ice machines and other products are more and more popular among the people. The refrigerant used in these products is mainly R134a, and the noise of the R134a refrigerant compressor is difficult to solve. a difficult problem. At present, the common noise reduction equipment has complex structure and cumbersome production, which increases the price of the compressor and even the entire refrigeration product, and the noise reduction effect is not ideal. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a suction muffler for a compressor, which can reduce noise through four muffler cavities and multiple expansion holes. [0004] The present invention...
