Embodiment Construction

[0021] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] Such as Figure 1 to Figure 3 As shown, according to the embodiment of the present invention, the muffler of the compressor includes a main body 10, the main body 10 is provided with an air chamber 19, and a perforated plate 20 is fixedly arranged in the air chamber 19, and the perforated plate 20 and the upper wall of the main body 10 A back pressure chamber is formed, and vent holes 21 are arranged on the perforated plate 20 . The air chamber 19 of the muffler of the compressor is used for containing the gas output by the compressor, and muffles the sound. By arranging the perforated plate 20 in the air chamber 19, the wide-band noise reduction effect of the perforated plate 20 is used to increase the noise reduction bandwidth of the silencer and improve the noise reduction performance of the silencer. Make the noise reduction effect better and ...

Abstract

The invention provides a silencer of a compressor and the compressor comprising the silencer. The silencer comprises a main body; a gas accommodating cavity is formed in the main body; a perforated plate is fixedly arranged in the gas accommodating cavity; a back pressure cavity is formed by the perforated plate and the upper wall of the main body; and vent holes are formed in the perforated plate. The silencer of the compressor has the better silencing effect.

Description

technical field [0001] The invention relates to the field of air conditioning equipment, in particular to a muffler for a compressor and a compressor with the same. Background technique [0002] Air-conditioning compressors, especially rotary compressors, will generate noise during the working process due to the need to compress and exhaust gas, and there are relatively moving parts. The external transmission of these noises will affect the user experience and may also cause noise pollution. In order to reduce the noise generated when the air conditioner compressor is working, a muffler is usually installed in the compressor to reduce the noise, but the existing muffler can only reduce the noise in a certain frequency band, and the noise reduction effect is limited. Contents of the invention [0003] The present invention aims to provide a muffler for a compressor with better noise damping effect and a compressor with the same. [0004] The invention provides a muffler f...
