In the embodiment of the invention, a rotation speed threshold value can be preset, the rotation speed threshold value can be specifically set as the lowest rotation speed of the fan in the current mode, the current mode can be a refrigeration mode, a heating mode and the like, the lowest rotation speeds of the fans in different modes are possibly different, namely the rotation speed threshold values in different modes are possibly different, if the air guide structure is in a swing state, the current rotation speed of the fan is obtained, and is compared with the rotation speed threshold value to judge whether the current rotation speed of the fan is greater than the preset rotation speed threshold value.
If yes, go to step S203; if not, the process proceeds to step S204.
S203, controlling the rotating speed of the fan to be reduced to a rotating speed threshold value, controlling the angle of the air guide structure driven by the motor of the air guide structure to be increased to the maximum angle in the current mode, and limiting the maximum rotating speed of the fan.
In the embodiment of the invention, if the rotating speed of the fan is greater than the preset rotating speed threshold, the rotating speed of the fan is controlled to be reduced to the rotating speed threshold, and the angle of the air guide structure driven by the motor of the air guide structure is controlled to be increased to the maximum angle in the current mode, wherein the current mode can be a refrigeration mode, a heating mode and other modes, the maximum angles in different modes can be different, the temperature adjusting effect is improved, and the maximum rotating speed of the fan is limited.

In the embodiment of the present invention, the ac input voltage may be divided into a plurality of voltage range intervals in advance, for example, the low voltage threshold is 180V, and the voltage lower than 180V is divided into two intervals of [0, 150V ] and [150V, 180V).
And S302, setting the maximum rotating speed of the fan according to the voltage range interval, wherein the alternating current input voltage and the maximum rotating speed of the fan are in positive correlation.
In the embodiment of the invention, the maximum rotating speed of the fan is set according to the voltage range interval, and the alternating current input voltage and the maximum rotating speed of the fan are in positive correlation, namely the higher the alternating current input voltage is, the higher the maximum rotating speed of the fan is, the smaller the alternating current input voltage is, and the lower the maximum rotating speed of the fan is. For example, the maximum rotation speed of the fan in the [0, 150V) voltage range section is set to be 60% of the current gear rotation speed, and the maximum rotation speed of the fan in the [150V, 180V) voltage range section is set to be 80% of the current gear rotation speed.

When the alternating current input voltage of the air conditioner is smaller than the preset low voltage threshold value, the operation of the load is controlled according to the operation priority of each load of the air conditioner, and the basic temperature adjusting function of the air conditioner is guaranteed.
When the air conditioner runs in the air supply mode, the outdoor load is not needed to work, so that the main relay of the air conditioner is kept disconnected. At this time, if the ac input voltage is too low, the indoor unit of the air conditioner may not be able to detect the current voltage, and the load of the indoor unit is still driven according to the standard ac input voltage, which is likely to cause unstable load and even failure shutdown. Therefore, an embodiment of the present invention further provides a method for controlling an air conditioner, as shown in fig. 4, including:
and S401, running in an air supply mode.
S402, the air supply mode is started for the first time, and the main relay is closed for T1 seconds.
In the embodiment of the present invention, the main relay is closed, so that the indoor main control board may send an ac input voltage query command to the outdoor main control board, where T1 may be 40 seconds.

And S406, judging whether the difference value between the current running wind speed set duty ratio of the indoor fan and the actual driving duty ratio of the fan is larger than D2 and whether the duration is larger than or equal to M2.
