Abstract

The present invention is one kind of silencer for rotary compressor. In the compressor compressing the sucked refrigerant in certain pressure, the silencer covers the compressed refrigerant exhaust port at upper bearing to reduce noise produced during exhaust refrigerant. Structurally, the silencer of the present invention features that its edge contacting with the upper bearing is set with key way to raise the sealing property between the upper bearing and the silencer. The said structure has the silencing effect of preventing refrigerant leakage via the gap between the upper bearing and the silencer and lowering noise.

Description

technical field [0001] The present invention relates to a noise reduction device for a rotary compressor. Background technique [0002] Typically, a rotary compressor is a mechanical device that relies on a rotor inside a rotating cylinder to compress refrigerant gas. Specifically: the eccentric roller arranged at the lower part of the crankshaft makes revolution and rotation along the inner surface of the cylinder to compress the refrigerant. The accumulator mounted on the hermetic compressor has a separation function for separating liquid refrigerant and its impurities from the refrigerant sucked into the rotary compressor. [0003] The rotary compressor with the above functions previously produced by the applicant LG Electronics (Tianjin) Electric Co., Ltd., such as figure 1 As shown, it has the following structure: the inside of the airtight container 1 forms a certain volume space, and has a suction pipe 14 and a discharge pipe 15; the inside of the airtight container...
