Abstract

The invention discloses a compressor. The compressor comprises a cylinder assembly, a bearing, a silencer and a silencing partition. The bearing is arranged on the end face of the cylinder assembly, a first exhaust hole is formed in the bearing, the silencer is arranged on the end face of the bearing, and a silencing cavity is defined by the silencer and the bearing. The silencing partition is arranged on the end face of the bearing, at least one part of the silencing partition is recessed in the direction away from the bearing so that a first sub silencing cavity can be defined by the silencing partition and the surface where the bearing is located, a second sub silencing cavity is defined by the silencing partition and the silencer, the first sub silencing cavity is communicated with the first exhaust hole, and a second exhaust hole for allowing the first sub silencing cavity and the second sub silencing cavity to be communicated is formed in the silencing partition. According to the compressor, the silencing partition is arranged between the bearing and the silencer, gas refrigerant exhausted into the silencer is silenced twice, and therefore the silencing amount of the compressor is increased. The compressor is simple in structure and small in increase of design cost and machining cost.

Description

technical field

[0001] The invention relates to the field of compressors. Background technique

[0002] The compressor is the core component of the refrigeration system, and its working characteristics determine that the compressor is also the main noise source of the refrigeration system. The compressor noise includes airflow noise, mechanical noise and motor noise. The muffler is a mechanism used to suppress the airflow noise of the compressor, and the muffler is generally installed on the bearing. Due to structural limitations, the traditional muffler has a small amount of noise reduction, and even in some frequency bands, the noise reduction effect of the muffler is poor, resulting in a limited overall noise reduction capability of the muffler. 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 aims to provide a compressor whose noise reduction...
