[0028] Working principle: First, the compressor 7 compresses the low-temperature gaseous refrigerant in the circulating water pipe 8 to form a high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant transfers heat to the cold water in the water tank through the heat exchange box 2 and the heat exchange spiral tube 102 to complete the heating of the cold water. The refrigerant after heat exchange forms a liquid refrigerant and is stored in the liquid storage tank 3. The liquid refrigerant enters the evaporator after passing through the expansion valve 4. Since the pressure of the liquid refrigerant in the evaporator 9 drops suddenly, the liquid refrigerant evaporates to form a gaseous refrigerant. When the fan 503 is working, it blows air to the evaporator. The heat of the air is absorbed by the evaporator 9 and transferred to the gaseous refrigerant to enter the next cycle. After frost forms on the outer wall of the evaporator, the heating component 502 generates heat, and the fan 503 promotes heat circulation, thereby heating the evaporator and promoting the melting of the frost. The melted frost is discharged through the water outlet pipe, thereby effectively improving the defrosting efficiency and effectively avoiding the adverse effects of the frost on the evaporator, thereby increasing the service life of the device.
