Problems solved by technology

[0004] Because the existing rotary compressor cannot provide a smooth exhaust passage for the exhaust, the resistance of the exhaust is large, and the backflow phenomenon is obvious, so that the high-pressure gas accumulates at the exhaust port, which is not conducive to exhaust, and then affects the work of the rotary compressor. Efficiency adversely affects

Abstract

The invention provides a compressor drainage cover and a rotor compressor. The compressor drainage cover is arranged between a rotor and an upper flange and comprises a mounting part, a rotating component and a baffle part, wherein the mounting part is used for making the rotating component connected with the rotor; the rotating component is coaxially arranged in the baffle part and fixedly connected with the baffle part; and the baffle part is of a cylindrical structure, and the bottom of the baffle part is in clearance fit with a groove formed in the upper flange. Through the application ofthe compressor drainage cover, a smooth exhaust passage is provided for exhaust gas, so that the resistance and backflow of the exhaust gas are reduced, accumulation of high-pressure gas at an exhaustport is facilitated, exhaust of the rotor compressor is facilitated, and the working efficiency of the rotor compressor is improved. The rotor compressor comprises the compressor drainage cover.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a compressor shroud and a rotor compressor. Background technique [0002] Rotary compressors are widely used in refrigeration equipment such as refrigerators and air conditioners due to fewer parts, small size, simple structure, light weight and reliable operation. The rotary compressor includes an eccentric cylindrical rotor and a cylinder, and the rotation of the rotor causes the working volume in the cylinder to change periodically to realize the cycle of suction, compression and exhaust. [0003] In the prior art, when the rotor compressor is working, the rotor structure only provides conventional air flow agitation for the exhaust, so that the high-pressure gas discharged from the exhaust port of the cylinder mainly relies on free diffusion for exhaust. [0004] Because the existing rotary compressor cannot provide a smooth exhaust passage for the exhaust, the resistance of the e...
