Snow ice maker

Abstract

The present invention relates to a snow ice maker, comprising a coupling shaft (40) assembly wherein refrigerant injection capillary tubes (20) and a refrigerant gas outlet tube (30) are arranged in a main passage (41), and the passage (41) is closed at a welding part (43) as a result of the capillary tubes (20) and a refrigerant gas inlet tube being simultaneously provided. The refrigerant injection capillary tubes (20) comprise ends (22) arranged in proximity to an injecting position inside a cooling drum, and the refrigerant injection capillary tubes (20) are arranged by collecting the refrigerant injection capillary tubes (20) in the passage (41) of the coupling shaft (40); extending the refrigerant injection capillary tubes (20) to the outside of the cooling drum; combining the refrigerant injection capillary tubes (20) at a multiple connection part (21); and directly connecting the refrigerant injection capillary tubes (20) to a refrigerant supply tube (52) of a refrigerant compressor. The refrigerant gas outlet tube (30) is connected to a multiple inlet tube (33) in an ice-making drum, and the refrigerant gas outlet tube (30) is arranged by directly connecting the refrigerant gas outlet tube (30) through the main passage in the coupling shaft (40), from a connection part (31) outside the cooling drum to a gas inlet tube (54) of a condenser. According to the present invention, clean snow ice can be used because supplied water for ice making is frozen in an ice-making drum, edible powder ice can be obtained by cutting the ice layers of the ice-making drum with a cutter, and water for ice making is sterilized by ultraviolet rays. In addition, the ice-making drum can be cleaned and sterilized by heated water and vapor so that ingredients including milk, sugar and juice can be ice-made and variously used in a summer environment of high temperature and humidity.

Description

technical field [0001] The invention relates to a shaved ice machine. More specifically, it relates to an ice machine that cools the drum by evaporating refrigerant in the drum, applies water to the surface of the drum to freeze it, and cuts the ice layer frozen on the surface of the drum with a knife to produce shaved ice. Background technique [0002] Korean Patent No. 0178693 discloses a cylindrical ice maker. This drum ice machine is a device that dips water on the surface of the drum and freezes it, and cuts the ice layer frozen on the surface of the drum with a knife to make block ice. The roller ice machine directly cuts the ice layer on the ice-making drum to make shaved ice. Therefore, compared with the existing ice cubes cut by a crusher or granulated ice cut by a cutting machine, the ice is softer and the particle size is equal, which can obtain Excellent edible shaved ice. [0003] An ice maker is a device that uses refrigerant to freeze water. Popsicle maker...

AI Technical Summary

Problems solved by technology

This refrigerant cycle device has two tubes, and its structure is complicated, and failures such as blockage of the flow path occur, so the manufacturing cost and operating cost increase.

[0008] And, one of the existing critical problems is that it is difficult to keep the ice machine clean because ice making contains materials such as milk, white sugar, fruit juice, etc.

In particular, in the high temperature and humidity environment in summer, residues such as milk and sugar left in the ice machine are easy to rot, which causes serious problems
