Abstract (en)

[origin: EP3879192A1] The present application provides an air conditioner cleaning device, including a fresh air device (1). The fresh air device (1) is capable of introducing fresh air into a room, and is capable of supplying air to the heat exchanger. The present application can be used for self-cleaning of an outdoor heat exchanger, with high cleaning efficiency and good cleaning effect. The fresh air device has a dual-passage selective air-introduction, making full use of the temperature difference between the indoor air and the outdoor air, speeding up the frosting and defrosting processes, and improving the self-cleaning efficiency of the air conditioner. The humidification and cooling of the frosting airflow and the heating of the defrosting airflow are realized on the basis of the fresh air device, which can speed up the frosting and defrosting processes and improve the self-cleaning efficiency of the air conditioner. It can be used for self-cleaning of both the indoor heat exchanger and the outdoor heat exchanger, so the functions are completed.
