And S106, controlling the indoor unit to send out information for prompting that the dust accumulation of the indoor unit is serious.
In the embodiment of the invention, after the indoor unit is judged to be seriously dusty, the indoor unit is controlled to send out information for prompting that the dust of the indoor unit is seriously dusty, and a user is reminded to clean the filter screen.
S107, after the interval setting time, the process proceeds to step S101.
In the embodiment of the invention, after the indoor unit is judged to be seriously dusty and the set time is set at intervals, the step of judging whether the indoor unit reaches the stable working condition is continuously executed, namely the step S101 is continuously executed, wherein the set time can be 40000 minutes.
