At present, the air supply drying of the air conditioner used in daily life mostly adopts a strategy of constant air supply time. However, under different operating conditions of the air conditioner, the amount of condensed water generated by the indoor unit is different, and if the amount of the condensed water generated is less, the consumption of electric energy is inevitably increased due to the overlong air supply time, so that unnecessary waste is caused; if more condensed water is generated, the air supply time is not enough and the internal machine cannot be completely dried, so that the fins, the air duct and other parts of the evaporator of the internal machine become moldy.

Specifically, when the air conditioner operates in a cooling mode, the indoor temperature and the indoor air humidity are detected by the sensor, and the outlet air temperature of the air conditioner or the temperature of the evaporator tube is detected to obtain the difference between the outlet air temperature or the temperature of the evaporator tube and the air dew point. And the air dew point is calculated according to the indoor temperature and the indoor air humidity.
When the air conditioner operates in a cooling mode, the internal temperature of the indoor unit is low, and when hot air in the external environment enters the indoor unit and contacts with cold air, condensed water is generated, and the generated condensed water is gradually increased along with the extension of the operation time of the air conditioner.
Step S120, when the air conditioner is turned off in the cooling mode, a preset air supply operation is performed according to the air outlet temperature or the temperature difference between the evaporator tube temperature and the air dew point detected before the air conditioner is turned off, that is, the generated condensed water is dried through the air supply operation, that is, the air is supplied to and dried on the fins, the base, the air duct, and the like of the evaporator component.
Specifically, when the air conditioner receives a shutdown signal, actions of closing the compressor and closing the four-way reversing valve are executed. And executing preset air supply operation according to the detected outlet air temperature or the temperature difference between the evaporator tube temperature and the air dew point before shutdown. That is, the air dew point is calculated according to the air humidity and the indoor temperature collected before the compressor is stopped, the preset air supply operation is executed according to the temperature difference between the air outlet temperature of the air conditioner indoor unit before the compressor is stopped and the calculated air dew point or the temperature difference between the evaporator tube temperature and the calculated air dew point, and the evaporator is supplied with air.
Specifically, if the temperature difference between the outlet air temperature and the air dew point or the temperature difference between the evaporator tube temperature and the air dew point is less than or equal to a preset temperature value, executing a first air supply operation; if the air outlet temperature or the temperature difference between the evaporator tube temperature and the air dew point is greater than a preset temperature value, judging whether the running time of the air conditioner is greater than preset time; if the running time of the air conditioner is judged to be greater than the preset time, executing a third air supply operation; otherwise, the second blowing operation is performed.
In one embodiment, the preset blowing operation includes: a first air blowing operation, a second air blowing operation, and a third air blowing operation. A first air blowing operation including: controlling the air deflector to a set angle, and discharging air in a preset wind shield for a duration t 1; a second air blowing operation including: controlling the air deflector to a set angle, and discharging air in a preset wind shield for a duration t 2; a third air supply operation including: controlling the air deflector to a set angle, and discharging air in a preset wind shield for a duration t 3; wherein t1 < t2 < t 3. The preset wind gear is a mute gear, for example.
In another embodiment, auxiliary electric heating drying can be added, and the air supply drying time can be shortened to a certain extent. Specifically, the preset air supply operation includes: a first air blowing operation, a second air blowing operation, and a third air blowing operation. A first air blowing operation including: controlling the air deflector to a set angle, and discharging air in a preset wind shield for a duration T1; a second air blowing operation including: controlling the air deflector to a set angle, starting the auxiliary electric heating device, and discharging air in a preset wind shield for a duration T2; a third air supply operation including: controlling the air deflector to a set angle, starting the auxiliary electric heating device, and discharging air in a preset wind shield for a duration T3; wherein T1 < T2 < T3. The preset wind gear is a mute gear, for example. T1 < T1, T2 < T2, and T3 < T3.
When the air conditioner operates in a refrigeration mode, the internal temperature of the indoor unit is low, when hot air in the external environment enters the indoor unit and contacts with cold air, condensed water is generated, and the yield of the condensed water is gradually increased along with the extension of the operation time of the air conditioner, so that the larger the difference between the outlet air temperature before the air conditioner is shut down or the temperature of an evaporator tube and the dew point of the air is, the more the generated condensed water is, the longer the refrigeration operation time of the air conditioner is, the more the generated condensed water is, and the more the generated condensed water is, the longer the air supply time is; therefore, if the difference between the outlet air temperature or the evaporator tube temperature and the air dew point is less than or equal to a preset temperature value, a first air supply operation is executed, and if the running time of the air conditioner is greater than a preset time under the condition that the outlet air temperature or the difference between the evaporator tube temperature and the air dew point is greater than the preset temperature value, a third air supply operation is executed, otherwise, a second air supply operation is executed.

The preset wind gear is a mute gear, for example. T1 < T1, T2 < T2, and T3 < T3.
When the air conditioner operates in a refrigeration mode, the internal temperature of the indoor unit is low, when hot air in the external environment enters the indoor unit and contacts with cold air, condensed water is generated, and the yield of the condensed water is gradually increased along with the extension of the operation time of the air conditioner, so that the larger the difference between the outlet air temperature before the air conditioner is shut down or the temperature of an evaporator tube and the dew point of the air is, the more the generated condensed water is, the longer the refrigeration operation time of the air conditioner is, the more the generated condensed water is, and the more the generated condensed water is, the longer the air supply time is; therefore, if the difference between the outlet air temperature or the evaporator tube temperature and the air dew point is less than or equal to a preset temperature value, a first air supply operation is executed, and if the running time of the air conditioner is greater than a preset time under the condition that the outlet air temperature or the difference between the evaporator tube temperature and the air dew point is greater than the preset temperature value, a third air supply operation is executed, otherwise, a second air supply operation is executed.
