The technical solution of the present invention and how to solve the above technical problems will be described in detail with specific examples.

The flexible suction structure for a refrigeration compressor provided by the present application is disposed on a shell 10 of the refrigeration compressor, as shown in fig. 1 and 2, and includes an elastic transition pipe 100, a suction pipe 300, and a plastic pipe 200 penetrating through the shell 10, wherein a first end of the elastic transition pipe 100 is connected to a suction noise reduction chamber 20 of the refrigeration compressor, a second end of the elastic transition pipe 100 is connected to a first end of the plastic pipe 200, and a second end of the plastic pipe 200 is connected to the suction pipe 300. In the prior art, suction pipe 300 is generally of unitary construction, using a metal pipe, starting from suction muffler chamber 20 of the refrigeration compressor, passing through casing 10 of the refrigeration compressor. The suction pipe 300 is heated due to the high temperature of the heat source existing in the casing 10, so that the refrigerating efficiency of the refrigerating compressor is lost. The plastic pipe 200 may be made of a material commonly used in industrial production, has a certain strength, and has better heat insulation performance than a metal pipe, so that when passing through the shell 10 of the refrigeration compressor, the refrigerant gas flowing through the pipe can be prevented from being heated, thereby effectively improving the refrigeration efficiency.

The flexible air suction structure for the refrigeration compressor changes the scheme of a metal air suction pipe 300 without a heat insulation effect in the prior art, adopts a three-section structural design of an elastic transition pipe 100, a plastic pipe 200 and the air suction pipe 300, the plastic pipe 200 penetrates through a shell 10 with heat inside, and the characteristic that the plastic pipe 200 has the heat insulation effect is utilized, so that the refrigerant gas is effectively prevented from being heated when passing through, and the refrigeration efficiency of the refrigeration compressor is improved.

Optionally, in an embodiment of the present application, as shown in fig. 3, the flexible suction structure for a refrigeration compressor further includes a clip 400, and the elastic transition pipe 100 is connected to the suction muffling chamber 20 and the plastic pipe 200 through the clip 400, respectively. The elastic transition pipe 100 and the suction silencing cavity 20 of the refrigeration compressor can be conveniently assembled through the clamp 400, and similarly, the elastic transition pipe 100 and the plastic pipe 200 can be conveniently assembled. Optionally, the clip 400 is a snap ring. Through the size and shape of the elastic transition pipe 100, the connecting buckle of the air suction silencing cavity 20 and the plastic pipe 200, the three can be connected through the matching of shape and size, and then the elastic locking clamping ring is arranged to strengthen the connection strength. The tail portion is mediated to elasticity locking snap ring accessible, can realize opening of elasticity locking snap ring greatly, can elastic clamping after loosening, and the operation is very convenient.

Alternatively, in one embodiment of the present application, as shown in fig. 4 and 5, the plastic tube 200 includes a first tube part 210 and a second tube part 220, and the first tube part 210 is butted against the second tube part 220. Since the plastic pipe 200 needs to pass through the housing 10, the entire plastic pipe 200 is not easily mounted on the housing 10, and is divided into two parts that can be coupled, one part can be mounted first, and the other part can be coupled, so that the plastic pipe 200 can be conveniently mounted in the housing 10. Specifically, the first pipe portion 210 may be provided with a portion having a small outer diameter, and the second pipe portion 220 may be provided with a mating port having a large inner diameter, so that the two portions can be mated with each other. In addition, the plastic tube 200 may be embedded in the air suction pipe 300, that is, the plastic tube 200 is partially disposed in the lumen of the air suction pipe 300.

Optionally, in combination with the previous embodiments, in a certain implementation manner of one embodiment, the plastic tube 200 further includes a heat insulation film (not shown in the figure), and the heat insulation film is wrapped on the peripheral side wall of the plastic tube 200. To further reduce the conduction of heat from the housing 10 to the plastic tube 200, particularly by radiation, a heat insulating film, such as aluminum foil, may be applied to the exterior of the plastic tube 200. The heat radiation is insulated as far as possible outside the plastic tube 200 by means of the aluminum foil.

Optionally, in a specific implementation of an embodiment, the elastic transition tube 100 is a bellows. The elastic transition pipe 100 is used to connect the plastic pipe 200 with the air suction and noise reduction cavity 20 made of metal, so the elastic transition pipe 100 can be made of rubber material with certain elasticity to facilitate the sealing connection with the plastic pipe 200 and the air suction and noise reduction cavity 20. The axial flexibility of the connecting pipe can be further improved by adopting the corrugated pipe, so that the whole flexible air suction structure can be stably arranged in the refrigeration compressor.
