Abstract

The invention discloses a rotary compressor and a refrigeration device. The rotary compressor includes: a cylinder, the cylinder has a cylinder chamber and a sliding vane groove; an exhaust hole, the exhaust hole communicates with the cylinder chamber; a piston; a crankshaft, the crankshaft is used to drive the The piston rotates eccentrically in the cylinder chamber; the upper bearing and the lower bearing; the sliding plate is arranged in the sliding plate groove and can reciprocate between the inner limit position and the outer limit position; the exhaust valve plate, The exhaust valve plate is used to open and close the exhaust hole; the transmission component drives the transmission component to push the exhaust valve plate to close the exhaust hole when the sliding plate moves outward, wherein the transmission component has a function for The contact surface that is in contact with the exhaust valve plate, the contact surface is a plane. According to the compression mechanism of the present invention, the applicability and reliability of the exhaust valve plate are good, the closing noise is low and the energy efficiency is high.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a rotary compressor and a refrigeration device. Background technique [0002] The discharge valve plate is an important part of the rotary compressor, and the discharge valve plate affects the energy efficiency, power consumption, noise, etc. of the compressor. Various improvements to the structure and material of the exhaust valve plate itself have been proposed in the related art, but each of these improvement solutions has its own problems, so there is a demand for improvement. The present invention is based on the inventor's discovery and recognition 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 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. [0004] The in...
