Abstract

The invention discloses a compression mechanism and a refrigeration device. The compression mechanism comprises an air cylinder, an exhaust hole, a piston, a crankshaft, an upper bearing, a lower bearing, a sliding sheet, an exhaust valve plate and a horizontal moving component. A cylinder chamber and a sliding sheet groove are arranged in the air cylinder, the exhaust hole communicates with the cylinder chamber, the crankshaft is used for driving the piston to eccentrically rotate in the cylinder chamber, the upper bearing and the lower bearing rotatably support the crankshaft, the sliding sheet is arranged in the sliding sheet groove and can move back and forth between an inner limit position and an outer limit position, the inner end of the sliding sheet abuts against the piston, the exhaust valve plate is used for opening and closing the exhaust hole, when sliding outwards, the sliding sheet drives the horizontal moving component to horizontally move to push the exhaust valve plateto close the exhaust hole, the horizontal moving component comprises a main horizontal moving part and an auxiliary horizontal moving part, the sliding sheet drives the main horizontal moving part tohorizontally move when moving outwards, the main horizontal moving part drives the auxiliary horizontal moving part to horizontally move to push the exhaust valve sheet to close the exhaust hole, andthe horizontal moving direction of the main horizontal moving part is orthogonal with that of the auxiliary horizontal moving part. According to the compression mechanism, the exhaust valve plate isgood in applicability 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, in particular to a compression mechanism and a refrigeration device with it. 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 understanding of the following facts and problems: In the related art, the exhaust valve plate of a rotary compressor is usually a reed valve plate with a certain degree of elasticity, that is, a certain rigidity. One end of the air valve plate is fixed, and the other end is free to open and close the air vent. [0...
