Air conditioner, rotary compressor and its pump body assembly

Abstract

The invention discloses an air-conditioner, a rotary compressor and a pump body component thereof. The pump body component comprises an air cylinder, a roller positioned in a compressing cavity of the air cylinder. a sliding piece and a flange provided with a vent hole, wherein the top end surface of the sliding piece is a raised surface and connected with the roller, a communicated groove is formed in the flange, and one end of the communicated groove is communicated with the vent hole; the communicated groove is positioned on one end, close to the sliding piece, of the vent hole, a conductive groove is formed in the top end surface of the sliding piece, and a sealing crescent groove is formed between the sliding piece and the roller; the crescent groove is positioned on one side, which is far from the vent hole, of the sliding groove, one end of the conductive groove is communicated with the crescent groove, and the other end of the conductive groove is communicated with the other end of the communicated groove. The problems that the rotary compressor is high in power dissipation and low in energy efficiency are effectively solved by virtue of the structural design of the pump body component.

Description

technical field [0001] The invention relates to the technical field of air conditioners, more specifically, to an air conditioner, a rotary compressor and a pump body assembly thereof. Background technique [0002] The rotary compressor is a kind of air conditioner compressor, which includes a motor part and a pump body assembly, wherein the pump body assembly includes a cylinder, a roller located in the compression chamber of the cylinder, a sliding vane that is in contact with the roller and reciprocates, The crankshaft that drives the roller to rotate and the flange that is sealed with the cylinder, etc. Among them, the top end surface of the sliding vane is connected with the roller to separate the cylinder compression chamber into a high-pressure chamber and a low-pressure chamber. There is an exhaust hole on the flange. The exhaust hole is located on one side of the sliding vane and the gas compressed by the compressor flows from the Exhaust through the exhaust hole o...
