Abstract

The invention relates to a check valve structure and an air conditioner. The check valve structure comprises a check valve assembly and a filtering assembly. The check valve assembly comprises a hollow valve body, an elastic part and a piston, wherein the piston is arranged in the valve body, one end of the elastic part is arranged on the piston, and the other end of the elastic part is arranged on the valve body. A mounting groove is formed in the valve body, the filtering assembly is arranged in the mounting groove, solid impurities in refrigerants can be removed through a filtering screen and prevented from blocking the check valve structure so that the solid impurities cannot enter a pipe system, and the normal operation of the air conditioner is guaranteed; meanwhile, the filtering assembly is arranged in the check valve assembly so that the size of the air conditioner can be reduced.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a check valve structure and an air conditioner including the check valve structure. Background technique [0002] The one-way valve for air conditioner is installed in the air conditioner pipeline, so that the refrigerant can be forwardly conducted and reversed to be closed. The one-way valve used in the existing air conditioner does not have the filter function. When the refrigerant in the air-conditioning pipeline flows, it will drive the solid impurities to flow together. The solid will block the one-way valve when the impurities pass through the one-way valve. Even if the one-way When the valve is forward-conducting, the refrigerant cannot pass through the one-way valve, which affects the performance of the air conditioner. The air conditioner filter is installed in the air conditioner pipeline for the purpose of removing and storing solid impurities, and is mainly composed o...
