Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning liquid storage devices, in particular to a filter screen structure of an air-conditioning liquid storage device. Background Art

[0002] The air conditioner accumulator is composed of a cylinder, an air inlet pipe, an air outlet pipe, a filter and other parts. During the operation of the air conditioning system, it cannot be guaranteed that the refrigerant can be completely vaporized; that is, some liquid refrigerant coming out of the evaporator will enter the accumulator. Since the unvaporized liquid refrigerant is heavier than the gas, it will directly fall to the bottom of the accumulator cylinder, and the vaporized refrigerant will enter the compressor from the outlet of the accumulator, thus preventing the compressor from inhaling liquid refrigerant and causing liquid hammer. In order to prevent impurities in the pipeline from directly entering the compressor, a filter will be installed between the accumulator inlet pipe and the outlet pipe to prevent the possibility of impurities entering the compressor.

[0003] According to a filter screen structure for an air conditioner liquid reservoir disclosed on the patent website (authorization announcement number: CN210345981U), "The utility model discloses a filter screen structure for an air conditioner liquid reservoir, which relates to the technical field of liquid reservoirs, including a filter screen fixing seat and a filter screen, wherein the outer side of the filter screen fixing seat is provided with a flange and the filter screen is fixed by the flange, and the filter screen is provided with a plurality of through holes, and a stretching groove for installing the air inlet port of the positioning steel pipe is provided at the geometric center of the bottom of the filter screen fixing seat, and the convex direction of the stretching groove faces one side of the filter screen. The filter screen structure of the utility model is suitable for an air conditioner liquid reservoir with an internal steel pipe fixing structure. On the basis of not adding components, the filter screen fixing seat is improved to realize the fixing of the steel pipe inside the liquid reservoir. The fixing structure has low cost and simple processing. At the same time, the concentricity of the steel pipe and the liquid reservoir is high, which improves the product quality and market competitiveness."

[0004] Based on the above, the applicant believes that there are the following defects:
