When the liquid level in the water tray needs to be reduced or water is supplied to the outside, the liquid level in the water tray is detected by the middle float liquid level meter, when the liquid level is higher than the liquid level height corresponding to the middle liquid level signal, the water pump can be controlled to be powered on, and the three-way valve connected with the outlet of the water pump controls water drainage or water supply to the outside. According to the liquid level sensing device of the water pump, when the liquid level is too low and the liquid level sensing device is triggered, the water pump is automatically closed. When the water pump induction function is invalid, the water pump can be turned off in a delayed manner by on-off signals of the middle position floater, so that the water pump is prevented from idling and being damaged.
The above description is only the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the concept of the present invention within the technical scope disclosed in the present invention.
