the camera image detects that the self-cleaning effect on the heat exchanger reaches the standard, the heat exchanger does not need to be cleaned for the second time, at the moment, when the indoor fan runs reversely, the windshield of the indoor fan is directly arranged to be the high windshield to run for t3 time, and then the heat exchanger is dried quickly, and hot air is directly discharged outdoors from the exhaust pipeline.
The invention comprises the following steps: the self-cleaning function of the air conditioner is realized by that the indoor unit is reversed by the four-way valve after the condensation and frosting of the indoor unit are carried out to a certain degree in a refrigeration mode, so that the indoor unit enters a defrosting, sterilizing and drying process, when the air conditioner is self-cleaned and ready to enter a high-temperature sterilization drying stage, the control panel controls the fan of the indoor unit to reversely rotate, the exhaust fan of the exhaust device is started, meanwhile, the cover plate on the air inlet panel closes the air inlet of the indoor unit, the air is blown to the heat exchanger of the indoor unit from the indoor and is converted into hot air through the heat exchange of the heat exchanger, the hot air blows up the larger dirty sundries on the heat exchanger, under the drive of the air exhaust fan, the outdoor exhaust in-process of indoor hot air can be discharged the great dirty debris suction on the heat exchanger from the exhaust pipe to the open air, and the travelling comfort when the user experience air conditioner automatically cleaning has both been guaranteed to this mode, and the secondary cleans the air conditioner heat exchanger again, improves the automatically cleaning dynamics of air conditioner.
The air speed and the air quantity of the indoor fan can be adjusted according to the difference of the impurity degree on the heat exchanger. When the concentration of PM2.5 detected by the dust sensor is greater than or equal to a target set value, namely, more large sundries are deposited on the heat exchanger, the inner fan is set to operate at a low wind shield for t1 time when rotating reversely, the sundries on the heat exchanger begin to loosen after the internal temperature of the indoor unit reaches a required temperature point, the wind shield of the indoor fan is rotated to be at a high wind shield for t2 time, the indoor fan is rapidly made to fall off, and the fallen dirty sundries are sucked out of the outdoor in the process that hot air is discharged from the air exhaust pipeline. When the indoor unit just enters the defrosting, sterilizing and drying process, the heat exchanger is wet, so that the dust has larger adhesive force, the indoor unit cannot be loosened even if the indoor unit runs in a high windshield, and the energy consumption can be better saved when the indoor unit runs in a low windshield. When the dust begins to loosen, the dust is converted into a high windshield to run so as to quickly fall off. When the concentration of PM2.5 detected by the dust sensor is smaller than a target set value, namely the self-cleaning effect on the heat exchanger reaches the standard, the heat exchanger does not need to be cleaned for the second time. At the moment, when the indoor fan runs reversely, the windshield of the indoor fan is directly set to be a high windshield, the heat exchanger is quickly dried after t3 time, and hot air is directly discharged out of a room from the exhaust pipeline.
