Abstract

The invention discloses a water level detection method and device of a cooling fan and the cooling fan. The method comprises the steps: acquiring the working voltage of a water pumping device of a cooling fan during working; comparing the working voltage with a preset voltage to obtain a comparison result, the preset voltage being the working voltage of the water pumping device when the water level in the water tank is smaller than or equal to a lower limit value; and determining whether a water storage device of the cooling fan lacks water according to the comparison result. The technical problem that an existing water level detection method for the cooling fan is inaccurate in detection is solved.

Description

technical field [0001] The invention relates to the field of home appliance control, in particular to a water level detection method and device for a cooling fan and the cooling fan. Background technique [0002] The cooling fan is a kind of refrigeration equipment, which continuously pumps out the water in the water tank by using a circulating water pump, and sprays it evenly on the evaporation filter layer through the water distribution system. The outdoor hot air enters the evaporative cooling medium. The heat exchange between the inside and the water is fully carried out, and the cool and clean air cooled by the evaporation of water is sent into the room by the low-noise fan, so that the hot air in the room is discharged to the outside, so as to achieve the purpose of cooling the room. [0003] When the water level in the water tank of the cooling fan is higher than the lower limit of the water level, the water pump works normally; when the water level in the water tank ...
