Abstract

The invention discloses a rotary compressor and a refrigerating device. The rotary compressor comprises an air cylinder, an exhaust hole, a piston, a crankshaft, an upper bearing and a lower bearing,a slip sheet, an exhaust valve plate and a transmission part, wherein the air cylinder is internally provided with a cylinder chamber and a slip sheet slot; the exhaust hole communicates to the cylinder chamber; the crankshaft is used for driving the piston to rotate eccentrically in the cylinder chamber; the slip sheet is arranged in the slip sheet slot and can move in a reciprocating manner between an inner limiting position and an outer limiting position; the exhaust valve plate is used for opening and closing the exhaust hole; and the slip sheet moves outward to drive the transmission partto push the exhaust valve plate to close the exhaust hole, wherein the transmission part is provided with a contact surface in contact with the exhaust valve plate, and the contact surface is a plane. According to a compression mechanism, the exhaust valve plate is good in adaptability and reliability, low in closing noise and high in energy efficiency.

Description

technical field [0001] The present invention relates to the technical field of compressors, and in particular, to a rotary compressor and a refrigeration device. Background technique [0002] The exhaust valve plate is an important part of the rotary compressor, and the exhaust valve plate affects the energy efficiency, power consumption and noise of the compressor. In the related art, various improvements have been proposed for the structure and material of the exhaust valve sheet itself, but these improvement solutions all have their own problems, so there is a need for improvement. The present invention is made based on the inventors' findings and understanding of the following facts and problems: [0003] In the related art, the discharge valve plate of the rotary compressor is usually a reed valve plate with a certain elasticity, that is, a certain rigidity. One end of the discharge valve plate is fixed, and the other end is free to open and close the exhaust hole. ...
