s06: during the self-cleaning process of the evaporator 21, the residual volume in the waste water bin 60 is detected in real time, if the residual volume in the waste water bin 60 is sufficient, the step S71 is executed, the self-cleaning of the evaporator 21 is continued, and the step S08 is executed after the cleaning is finished; if the residual amount in the wastewater bin 60 is not enough, executing step S72;
s72: if the residual volume in the wastewater bin 60 is detected to be insufficient in the self-cleaning process of the evaporator 21, a user is reminded to clean the wastewater in time through display panel indicating lamps or alarm sound prompts and other modes; if the user cleans the waste water bin 60 in time, when the waste water bin 60 is drawn out of the machine body, the system temporarily exits from the evaporator 21 self-cleaning mode, and the user can continue cleaning after inserting the waste water bin 60 back; if the user does not clean the waste water bin in time, when the water amount in the waste water bin 60 reaches the upper limit, the evaporator 21 automatically exits from the self-cleaning mode, and the inner fan 22 rotates at a gentle breeze shift to dry the evaporator 21. Before the user finishes cleaning the wastewater bin 60, the system cannot enter the self-cleaning mode of the evaporator 21;
s08: after the evaporator 21 is self-cleaned, the inner fan 22 rotates for t1 minutes at a gentle wind level to dry the surface of the evaporator 21, and after drying, the air conditioner automatically turns to a pre-cleaning operation mode.
