Description

Technical Field

[0001] The present invention relates to the technical field of valve plates, and in particular to a compressor air intake valve plate, an air intake and exhaust valve assembly, a refrigerator and an air conditioner. Background Art

[0002] With the continuous improvement of energy conservation and emission reduction requirements, the compressor, as the core component and energy-consuming part of the refrigeration system, has also put forward higher requirements for its refrigeration performance and energy efficiency level. The suction valve plate is a one-way valve that controls the compressor to absorb refrigerant. It is a key component of the refrigerator compressor and directly affects the compressor's ability to absorb refrigerant and the overall cooling capacity. When the suction valve plate is working, the reed needs to vibrate continuously. Different suction pressures will cause different openings of the reed. When the existing suction valve plate has a high suction pressure, the opening of the reed is usually large, resulting in a large slapping force and noise generated during slapping, and a slow response speed, which shortens the service life of the suction valve plate.
