According to the drainage control method, when the air-conditioning range hood is in the air-conditioning starting mode, the condensed water condensed on the surface of the evaporator 33 flows into the second water box 12 of the water box 1, and the condensed water in the second water box 12 flows into the third water box 13 from the second water outlet hole 121 at a stable flow rate which is matched with the water outlet amount of the liquid distributor 6 and is less than the maximum flow rate of the water pump 17. The water pump 17 runs all the time from the start of the air conditioner, when the humidity of air is high, more condensed water is generated, the water pump 17 pumps all the instantly generated condensed water into the liquid distributor, and the liquid distributor 6 further conveys the condensed water to the surface of the condenser 32, so that the condenser 32 is further cooled and cooled, and the heat exchange effect of the condenser is improved. In addition, the condensed water output by the water pump 17 is already larger than the processing capacity of the liquid distributor 6, and the redundant condensed water flows into the water receiving box 4 and then flows back to the first water box 11, so that the recycling is realized.

Normally, the valve 16 is in a closed state, until the first water box 11 and the second water box 12 are full of water, the first float switch 14 is closed, the valve 16 is opened, the air conditioner is stopped, the indoor unit pure air supply mode is performed, and the air conditioner is restarted until no water exists in the first water box 11.

If the first float switch 14 is not started before the user turns off the air conditioner actively, the pure air supply mode is started by the internal unit after the user turns off the air conditioner actively, the water pump 17 continues to operate until the liquid distributor 6 finishes treating all the condensed water, and the whole machine is stopped.
