Problems solved by technology

[0007] However, when the check valve opens and closes due to the flow of refrigerant, the plunger installed inside it will rotate and move, and at this time, friction will occur with the outer casing, and noise will be caused by contact.
This friction causes the life of the check valve to be shortened, and noise causes the sensory quality of the air conditioner equipped with the check valve to decrease.

Abstract

The invention discloses a check valve and an air conditioner having the same, especially discloses a check valve capable of preventing the rotation of the plunger inside the check valve and reducing the check valve of the working noise and an air conditioner having the same. The check valve according to the invention includes a housing formed with a channel, a plunger which can provided on the channel movable in advance and retreat and forms at least one flank part on the lateral surface, a base opened and closed based on the end at one side of the plunger, a stop piece for limiting the advance and retreat moving of the plunger. The housing includes at least one spline hump, the spline hump is formed by projecting from the inner wall of the housing, to prevent the rotation of the plunger. And noise dropping hump formed by projecting to the stop piece is provided on the other end of the plunger.

Description

technical field [0001] The invention relates to a check valve and an air conditioner provided with the check valve, in particular to a check valve capable of preventing the rotation of the plunger inside the check valve and reducing working noise and an air conditioner provided with the check valve machine. Background technique [0002] Generally, air conditioners are generated when the refrigerant circulating in the system is vaporized or liquefied in a refrigeration cycle system that forms a closed loop by connecting the compressor, condenser, expansion valve, and evaporator through refrigerant pipes. A device that cools or heats the surrounding environment by endothermic and exothermic actions. [0003] Such air conditioners can be classified into a split type air conditioner and an integrated type air conditioner. The split type air conditioner includes an indoor unit and an outdoor unit respectively installed indoors and outdoors, and the indoor unit and the outdoor un...
