[0020] Working principle: The system determines the current temperature of water tank 1 through temperature sensor 103. If it is lower than the threshold, the heating rod 104 is started for heating. The heating is stopped after the temperature rises to the set threshold. If it is higher than the threshold, the water volume of water tank 1 is determined through liquid level sensor 102. The system liquid level sensor 102 determines the water volume in the water tank. If the water volume is insufficient, the water inlet electric valve 105 is opened, and the external water source enters through the water inlet pipe 101. The external water passes through the pre-filter 108 to filter out debris, and then the filter is backwashed. When the water level of water tank 1 exceeds the threshold, the water inlet electric valve 105 is closed, and the excess water is discharged through the overflow pipe 112.
