Valve bank assembly, compressor with valve bank assembly and refrigerator with valve bank assembly

Abstract

The invention provides a valve bank assembly, a compressor with the valve bank assembly and a refrigerator with the valve bank assembly. The valve bank assembly comprises a valve plate, an air suction valve plate, an air exhaust valve plate and a lift limiter. The valve plate comprises a steel valve plate main body, a groove and air suction ports, the groove is internally provided with an air exhaust port, and the air exhaust port is provided with a reinforcing rib. The exhaust valve plate is arranged in a first limiting structure in the groove and can close or open the exhaust port, and the lift limiter is arranged in a second limiting structure in the groove and can limit the lift height of the exhaust valve plate. The multiple air suction ports correspond to multiple air suction valves correspondingly, and the corresponding air suction ports can be closed or opened. The steel valve plate avoids the particle falling phenomenon possibly existing in the high-frequency operation of a powder metallurgy valve plate, and solves the problems of carbon deposition of the valve plate and failure of a valve bank. The reinforcing rib is designed at the exhaust port, so that the impact effect during high-frequency operation is effectively reduced, the contact area of the exhaust valve plate and the valve plate main body is increased, stress concentration is reduced, and the reliability of the exhaust valve plate and the energy efficiency of the compressor are improved.

Description

technical field [0001] The invention belongs to the technical field of refrigerator equipment, and in particular relates to a valve group assembly, a compressor and a refrigerator having the same. Background technique [0002] In the prior art, powder metallurgy concave valve plate is mostly used in the air valve assembly of the compressor. This air valve assembly is beneficial to reduce the suction resistance of the compressor, but the powder metallurgy valve plate may cause powder drop under the high-frequency impact of the valve plate. carbon deposits on the valve plate, which will cause the failure of the valve group; some people also propose to use a steel flat valve plate, and the valve plate is welded to the flat valve plate by pulsed fiber laser welding, so that the two become a whole, but this gas The valve assembly is not conducive to parts replacement, and the quality of parts is restricted by the welding process. Contents of the invention [0003] The present ...
