[0038] (2) Close the high temperature resistant drain valve 26 and set the third high temperature resistant reversing solenoid valve 18 to allow water to flow through the heating assembly.

[0039] (3) The high-speed water flow is heated to 70°C hot water, part of which is injected into the water tank 1 through the first water inlet branch, and then injected into the evaporator 2 through the ice-making main line, and part of the hot water is injected into the second water inlet branch. The evaporator 2, the water tank 1, the first water inlet branch and the second water inlet branch are kept full of hot water for 3 minutes and then emptied.
