Description

Technical Field

[0001] The utility model relates to the technical field of ice making machines, in particular to a one-way anti-backflow structure for ice making machines. Background Art

[0002] An ice maker is a refrigeration machine that cools water through an evaporator with the refrigerant of the refrigeration system to generate ice. It uses a refrigeration system and water as a carrier to make ice through a device under power-on. Commercial ice makers involve full drainage after ice making. The existing pipeline design is a straight-through pipe. Although drainage can be achieved, debris and other pollutants in the sink will flow back into the pipe, polluting the water quality of the ice maker and affecting internal hygiene and safety.

[0003] Based on the above problems, we propose a new one-way anti-backflow structure for ice making machines. Utility Model Content
