Description

Technical Field

[0001] This utility model relates to an ice maker with automatic water changing function. Background Technology

[0002] Industrial ice makers primarily produce large blocks of ice and are suitable for food processing, aquatic product processing, vegetable preservation, cold chain logistics, deep-sea fishing, chemical cooling, ice storage air conditioning, energy conservation, and environmental protection. After the compressor of an industrial ice maker starts running, the refrigerant undergoes processes such as suction, compression, exhaust, condensation (liquefaction), and throttling. Then, it evaporates and absorbs heat in the evaporator at a low temperature of -10℃ to -18℃, causing the chilled water to continuously condense into an ice layer on the surface of the evaporator at an even lower temperature of 0℃.

[0003] Before making ice, room temperature water needs to be added to the ice-making container. Usually, room temperature water is transported directly from the water collection tank to the ice-making container. Since the ice-making process is relatively long, it generally takes 8 to 10 hours to complete. However, the room temperature water stored in the water collection tank is difficult to preserve and will grow algae after being stored for a long time, which does not meet the requirements for ice making. Therefore, the room temperature water needs to be replaced. The replacement process and whether it needs to be replaced are done manually, which is time-consuming and inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide an ice maker with an automatic water-changing function, which can automatically change the water in the water collection tank without manual intervention, making it highly efficient and convenient.

Then, the control unit d drives the third solenoid valve c to open the water inlet pipe. 13. Water is stored in the water collection tank 1 through the inlet pipe 13. At the same time, the antibacterial device adds algaecide to the water collection tank 1 through the cleaning pipe 14 to disinfect algae. Then, the control unit d drives the third solenoid valve c to close the inlet pipe 13 and stop. Then, the control unit d drives the second solenoid valve b to open the drain pipe 12 to discharge the water containing algae. Then, the drainage is stopped by closing the second solenoid valve b and the third solenoid valve c is opened to store water in the water collection tank 1 through the inlet pipe 13.
