First, the water pump 4 is energized to work, and the water in the water tank 1 is delivered to the water supply container 3 through the water pipe 41 and the water pipe 42 in sequence. At this time, the water level is below the rated water level and the electric valve 8 is closed. In the water supply container 3, when the water level in the water supply container 3 reaches the rated water level line, the water level sensor 7 will detect the water level at this time and send a signal to the controller. 4 stop working, now because the water level sensor 7 detects and transmits the signal and the controller processes the signal and makes the water pump 4 stop working, it takes a certain period of time. During this time, the water pump 4 still works to add water to the water supply container 3, which will Cause the water level in the water supply container 3 to exceed the rated water level, and the excess water that exceeds the rated water level will flow back to the water tank 1 from the drain pipe 6, thereby ensuring that the water in the water supply container 3 is the rated water. On the other hand, after receiving the signal, the controller will control the electric valve 8 to delay opening so as to supply the rated water volume in the water supply container 3 to the ice making tray 21 for ice making.
