Description

Technical Field

[0001] The utility model relates to the field of snow melting machines, in particular to a barrel-type evaporator structure of a snow melting machine. Background Art

[0002] A snow melt machine is a machine used to make various fruit juices into cool and refreshing snow-melt drinks. It mainly includes a material tank, an evaporator and a stirrer. The evaporator, as a part of the refrigeration system of the snow melt machine, is placed in the material tank and is used to refrigerate the food raw materials in the material tank when working.

[0003] The existing snow melting machine has an evaporator that is mainly an inner and outer barrel structure. The refrigerant enters the inner and outer barrel interlayer to evaporate, but there is no spiral pipeline. The main disadvantages are that the inner and outer barrels must be sealed by welding, which has the risk of leakage. Second, the compressor oil is easily accumulated in the inner and outer barrels. The oil cannot return to the compressor, which will cause the oil to accumulate in the inner and outer barrel interlayer, affecting the heat exchange. At the same time, the less oil returned to the compressor will increase the wear of the compressor moving parts and reduce the service life of the product. Therefore, the applicant provides a new solution to the above-mentioned existing technical problems through improvement and perfection of the existing technology for consumers to choose and use.

[0028] This evaporator structure consists of an integrally formed spiral evaporator tube 3, with no welding points and no risk of leakage. The spiral evaporator tube 3 can push the compressor oil in the evaporator tube to flow back to the compressor due to the orderly flow of refrigerant, thereby protecting the compressor, increasing its life, and reducing noise. The evaporator tube 3 is fixed by the winding bracket 2, so that the evaporator tube 3 and the outer barrel 1 are closely fitted together, with stable dimensions and faster cooling.

[0037] The difference between the inner diameter of the evaporation tube 3 and the outer diameter of the winding tube 21 is H. In this embodiment, the difference H is preferably 1 mm.

[0038] The winding tube 21 includes an inner tube 211 and an outer tube 212, a hollow interlayer is formed between the inner tube 211 and the outer tube 212, and one end of the two is connected to form a closed end, and the other end is an open end, the inner limit cover 22 is connected to the closed end, the outer limit cover 23 is connected to the open end, and an outer cover opening 231 connected to the hollow interlayer 213 is opened on the outer limit cover 23; the hollow interlayer 213 has a heat insulation effect.

[0039] The outlet end 302 of the evaporator tube 3 is close to the outer limit cover 23, and the outer limit cover 23 is provided with a avoidance opening 232 corresponding to the outlet end 302.
