Description

Snow melting machine TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigeration device, and particularly relates to a snow melting machine. BACKGROUND

[0002] At present, the evaporator of the ice water machine, ice cream machine and snow melting machine is a spiral copper pipe evaporator. The spiral pipe is put into the inner or outer cylinder, and the refrigerant flows in the spiral pipe. The heat is transferred to the liquid to be cooled after the spiral pipe wall contacts the inner or outer cylinder. Due to the influence of the spiral pipe and the thickness of the inner and outer cylinder walls, the heat transfer path is not simple and direct, so the refrigeration effect is not ideal. Moreover, the spiral pipe has a certain gap, which determines that the spiral pipe cannot fully contact the inner or outer cylinder, resulting in poor heat transfer efficiency. After a period of use, the spiral pipe may be separated from the inner or outer cylinder due to its own tension and other factors, resulting in poor refrigeration effect or even no refrigeration. In addition, when the polyurethane foam filled as a thermal insulation layer material expands, it is easy to squeeze into the spiral pipe, causing the spiral pipe to separate from the inner or outer cylinder, which also leads to poor refrigeration effect or no refrigeration. Therefore, the spiral copper pipe evaporator has low refrigeration efficiency, poor work reliability, low heat transfer capacity, and high production cost due to the dense winding of the spiral pipe.

The evaporator of the refrigeration system is connected to be refrigerated. A rotary scraper structure scrapes the condensate on the outer surface of the evaporator. The main body 1 further includes a discharge structure. It further includes an inner cylinder 200, which is a cylindrical shell with both ends open and coaxial with the outer cylinder 100. The first end is connected to the end of the outer cylinder 100, and the second end is provided with a folded edge 210 outwardly, so that a closed refrigeration chamber a is formed between the inner cylinder 200 and the outer cylinder 100. The folded edge 210 is provided with a notch 211. The refrigeration chamber a is provided with a liquid inlet groove b in communication with the notch 211. The refrigeration medium enters the refrigeration chamber a through the liquid inlet groove b. The liquid inlet pipe 400 extends into the liquid inlet groove b through the notch 211.

[0055] The above is the basic scheme of the embodiment.

[0056] With specific reference to Figs. 1-4, the evaporator and the rotating blade structure are located inside the main body 1 and are closed by the ice-making cover.

[0057] With reference to Fig. 3, the outer cylinder 100 is provided as a housing with one end open and the other end having a bottom, and the inner cylinder 200 is located inside the outer cylinder 100 and is coaxially arranged with the outer cylinder 100. The inner cylinder 200 can be directly welded on the bottom of the outer cylinder 100 or can be sealingly connected with the outer cylinder 100 through a connecting part 7.

[0058] With reference to Fig. 4, the second end of the outer cylinder 100 is outwardly folded to be provided with a folded edge 210, and the outer end of the folded edge 210 is connected with the inner wall of the outer cylinder 100, so that a closed refrigeration chamber a is formed between the inner cylinder 200 and the outer cylinder 100. At the same time, a notch 211 is provided on the folded edge 210, and a liquid inlet groove b is provided in the refrigeration chamber a and is in communication with the notch 211 on the folded edge 210. The liquid inlet pipe 400 extends into the liquid inlet groove b through the notch 211. The refrigeration medium is input into the liquid inlet groove b through the liquid inlet pipe 400 and enters the refrigeration chamber a along the liquid inlet groove b. The refrigeration medium generates effect in the refrigeration chamber a, so that the outer cylinder 100 is refrigerated, and the liquid is condensed on the surface of the outer cylinder 100 and is scraped off by the scraper on the side of the outer cylinder 100.

[0059] In the embodiment, the open end of the outer cylinder 100 is provided with an end cover 900 for sealing.

[0060] In the embodiment, the refrigeration medium is a conventional refrigerant.

[0061] In the embodiment, the liquid inlet pipe 400 is a capillary tube, and the size of the notch 211 is at least capable of accommodating the liquid inlet pipe 400 to extend in.

[0062] In the embodiment, the refrigeration medium is continuously input into the refrigeration chamber a and contacts the inner surface of the outer cylinder 100, and the contact area is the entire inner surface of the outer cylinder 100. Compared with a spiral pipe, the contact area of the embodiment is large, and the refrigeration effect is good.

[0063] When the refrigeration medium works in the refrigeration chamber a, it absorbs the heat on the outer cylinder 100 and vaporizes to form gas. In order to avoid the gas filling in the refrigeration chamber a and affecting the input of the refrigeration medium, in the embodiment, the refrigeration chamber a is also communicated with an exhaust pipe 600, and the formed gas is output to the outside of the refrigeration chamber a through the exhaust pipe 600, so that the refrigeration medium can be continuously received in the refrigeration chamber a.

[0064] During use, the refrigeration medium is continuously input from the liquid inlet groove b into the refrigeration chamber a, and the gas formed by vaporization is output from the exhaust pipe 600, forming a cycle, so that the heat of the liquid can be continuously absorbed, ensuring the refrigeration effect of the evaporator.
