According to an exemplary embodiment, the present embodiment proposes a control method of an air conditioner, which is used to control the air conditioner according to any one of the foregoing embodiments, and fig. 10 is a control flowchart of the air conditioner according to an exemplary embodiment, and referring to fig. 10, the control method includes: acquiring the sand and dust density of an outdoor environment in the running state of the air conditioner; the first protective layer 41 and the filter layer 42 are controlled to cover the air intake 7 alone or simultaneously with the air intake 7 according to the density of the dust.

In this embodiment, the sand density of the outdoor environment may be obtained according to the sand sensor 6 disposed at the outdoor unit of the air conditioner, or may be determined by obtaining weather forecast data of the intelligent terminal after being in data communication with the intelligent terminal of the user. After determining the dust density, the driving mechanism can be controlled according to the dust density, and the first protective layer 41 and the filter layer 42 are driven by the driving mechanism to cover the air inlet 7 alone or cover the air inlet 7 at the same time.

In some embodiments, controlling the first protective layer 41 and the filter layer 42 to cover the intake vent 7 alone or simultaneously according to the dust density includes: controlling the first protective layer 41 and the filter layer 42 to open the air inlet 7 under the condition that the sand density is smaller than the minimum value of the target sand density range; controlling the first protective layer 41 to open the air inlet 7 and controlling the filter layer 42 to cover the air inlet 7 when the sand density is within the target sand density range; in the case where the dust density is greater than the maximum value of the target dust density range, the air conditioner is controlled to stop, and the first protection layer 41 and the filtration layer 42 are controlled to cover the air intake 7 at the same time.

In this embodiment, referring to fig. 10, the dust density is set to D, and the target dust density range is [ D ] ₀ D1), when the sand-dust density in the air is detected to exceed D0 but not exceed D1, it is determined that the sand-dust density is not too high, the driving mechanism is started, and the filter layer 42 of the back panel 2 and the outdoor unit side panel 3 of the air conditioner are closed, and at this time, the outdoor unit of the air conditioner is in a normal operation state.

At this time, the driving mechanism drives the filter layer 42 and the first protection layer 41 to be closed, the outdoor unit stops running, when the outdoor unit is in a shutdown state, the fan is not running any more, and the second protection layer 51 is also automatically closed, so that the internal devices of the shell are fully closed, and the outdoor unit is protected from being influenced by strong wind and sand. Meanwhile, when severe sand and dust weather occurs, the indoor air conditioner can send prompt information to a user.

In some embodiments, the control method further includes controlling the first protection layer 41 and the filtration layer 42 to cover the air intake 7 at the same time when the air conditioner is in a stopped state.

In this embodiment, when the air conditioner is in a shutdown state, the filter layer 42 and the first protection layer 41 are both in a closed state, so that components such as an outdoor heat exchanger and a controller in the housing are better protected, the service life of the air conditioner can be effectively prolonged, meanwhile, the influence of sand wind on the outdoor unit can be reduced, and the use effect of the air conditioner is ensured.
