As shown in fig. 1, the air supply control method of the air conditioner includes steps 101 to 103:
step 101, obtaining the current rotating speed of the air conditioner, the current of the air conditioner and the operating temperature of the air conditioner.
The current rotating speed of the air conditioner is the rotating speed of the indoor fan when the air deflector of the indoor fan of the air conditioner reaches the current position; the air conditioner current is the output value of the air conditioner indoor fan current; the air conditioner operation temperature is the operation temperature of an air conditioner indoor fan.
In some embodiments of the present application, there are a plurality of air conditioner current obtaining manners, which exemplarily include:

The air conditioner initial rotating speed comprises an initial rotating speed when the air conditioner is started and a rotating speed before air conditioner compensation. For example, taking the example that the target rotation speed of the air conditioner is the target rotation speed of the indoor fan of the air conditioner, when the target rotation speed of the indoor fan of the air conditioner is the initial rotation speed of the indoor fan of the air conditioner, the current rotation speed of the indoor fan of the air conditioner is reduced to the initial rotation speed when the indoor fan of the air conditioner is started or the compensation front rotation speed of the indoor fan of the air conditioner, and the indoor fan of the air conditioner is controlled to operate according to the initial rotation speed when the indoor fan of the air conditioner is started or the compensation front rotation speed of the indoor fan of the air conditioner.
(3) And when the target rotating speed of the air conditioner is the rotating speed increased according to the rotating speed compensation value, increasing the current rotating speed of the air conditioner to the target rotating speed of the air conditioner, and controlling the air conditioner to operate according to the target rotating speed of the air conditioner.

The method comprises the steps of obtaining the current rotating speed of the air conditioner, the current of the air conditioner and the operating temperature of the air conditioner; calculating a rotation speed compensation value of the current rotation speed of the air conditioner according to the current of the air conditioner and the running temperature of the air conditioner to obtain a target rotation speed of the air conditioner; controlling the air conditioner to operate according to the target rotating speed of the air conditioner; the current output of the air conditioner and the running temperature of the air conditioner are intelligently detected, the actual running rotating speed of the air conditioner is adjusted in real time through calculating rotating speed compensation, the maximum air supply requirement can be met all the time when the air conditioner air deflector runs to different positions, the maximum air volume output of the air conditioner under different windshields is kept, and the requirement of a specific environment is met.
In some embodiments of the present application, in order to ensure safe operation of the indoor fan of the air conditioner, in the process that the air conditioner operates at the target rotation speed of the air conditioner, temperature rise of the indoor fan of the air conditioner is detected, and whether the operation of the indoor fan of the air conditioner is safe is determined according to the detection result, wherein the temperature rise of the indoor fan of the air conditioner is a value of a difference between an operating temperature and an ambient temperature of a motor of the indoor fan of the air conditioner. Specifically, the method for detecting the operation safety of the indoor fan of the air conditioner comprises the following steps of a 1-a 4:
step a1, detecting the temperature rise of an indoor fan when the indoor fan of the air conditioner operates according to the target rotating speed of the air conditioner, and judging whether the temperature rise of the indoor fan reaches a preset temperature rise protection value.
And a2, if the temperature rise of the indoor fan exceeds a preset temperature rise protection value, the operation of the indoor fan of the air conditioner is unsafe, and the rotating speed of the indoor fan of the air conditioner needs to be reduced, adjusting the target rotating speed of the indoor fan of the air conditioner to the initial rotating speed of the indoor fan of the air conditioner, and controlling the indoor fan of the air conditioner to operate according to the initial rotating speed of the indoor fan of the air conditioner.
For example, taking the preset temperature rise protection value of 80 and the ambient temperature of 40 ℃ as an example for explanation, when the temperature rise of the indoor fan when the indoor fan of the air conditioner operates according to the target rotating speed of the air conditioner is detected to be greater than 80, that is, when the operating temperature of the indoor fan when the indoor fan of the air conditioner operates according to the target rotating speed of the air conditioner is detected to be greater than 120 ℃, it is indicated that the operation of the indoor fan of the air conditioner is unsafe, and the rotating speed of the indoor fan of the air conditioner needs to be reduced, the target rotating speed of the indoor fan of the air conditioner is adjusted to be the initial rotating speed of the indoor fan of the air conditioner, and the indoor fan of the air conditioner is controlled to operate according to the initial rotating speed of the indoor fan of the air conditioner.
And a3, if the temperature rise of the indoor fan is equal to a preset temperature rise protection value, which indicates that the operation of the indoor fan of the air conditioner reaches a safety limit value, and the rotating speed of the indoor fan of the air conditioner needs to be limited, controlling the air conditioner to continuously operate according to the target rotating speed of the air conditioner.
For example, taking the preset temperature rise protection value of 80 and the ambient temperature of 40 ℃ as an example, when the temperature rise of the indoor fan when the indoor fan of the air conditioner operates at the target rotation speed of the air conditioner is detected to be equal to 80, that is, the operating temperature of the indoor fan when the indoor fan of the air conditioner operates at the target rotation speed of the air conditioner is detected to be equal to 120 ℃, it is indicated that the indoor fan of the air conditioner is unsafe to operate, and the rotation speed of the indoor fan of the air conditioner needs to be reduced, the target rotation speed of the indoor fan of the air conditioner is adjusted to the initial rotation speed of the indoor fan of the air conditioner, and the indoor fan of the air conditioner is controlled to operate at the initial rotation speed of the indoor fan of the air conditioner.
And a4, if the temperature rise of the indoor fan is less than the preset temperature rise protection value, which indicates that the indoor fan of the air conditioner is safe to operate, compensating the target rotating speed of the air conditioner according to the current of the air conditioner by detecting the current of the air conditioner, and controlling the air conditioner to operate according to the compensated target rotating speed of the air conditioner.
For example, taking the preset temperature rise protection value of 80 and the ambient temperature of 40 ℃ as an example for explanation, when the temperature rise of the indoor fan when the indoor fan of the air conditioner operates according to the target rotating speed of the air conditioner is detected to be less than 80, that is, when the operating temperature of the indoor fan when the indoor fan of the air conditioner operates according to the target rotating speed of the air conditioner is detected to be less than 120 ℃, the operation safety of the indoor fan of the air conditioner is explained, the target rotating speed of the air conditioner is compensated according to the current of the air conditioner by detecting the current of the air conditioner, and the air conditioner is controlled to operate according to the compensated target rotating speed of the air conditioner.
In some embodiments of the present application, in order to ensure safe operation of the air conditioner, in step 202, a target rotation speed of safe operation of an indoor fan of the air conditioner may be determined according to an operating temperature of the air conditioner by detecting the operating temperature of the air conditioner, and specifically, the method includes steps b1 to b4:
and b1, comparing the operating temperature of the indoor fan in the operating temperature of the air conditioner with a preset temperature.
The preset temperature is the safe operation temperature of the indoor fan of the preset air conditioner.
And b2, if the operating temperature of the indoor fan is equal to the preset temperature, setting the current rotating speed of the air conditioner as the target rotating speed of the air conditioner.
And if the operating temperature of the indoor fan is equal to the preset temperature, the operating temperature of the indoor fan of the air conditioner reaches the safe operating temperature of the indoor fan of the air conditioner, namely the current rotating speed of the air conditioner reaches the safe rotating speed limit value of the air conditioner, and the current rotating speed of the air conditioner is set as the target rotating speed of the air conditioner. For example, the preset safe operating temperature of the indoor fan of the air conditioner is 120 ℃, and if the operating temperature of the indoor fan is equal to 120 ℃, the operating temperature of the indoor fan of the air conditioner reaches the preset safe operating temperature of the indoor fan of the air conditioner, that is, the current rotating speed of the indoor fan of the air conditioner reaches the safe rotating speed of the indoor fan of the air conditioner, the current rotating speed of the air conditioner is set as the target rotating speed of the air conditioner.
And b3, if the operating temperature of the indoor fan is higher than the preset temperature, setting the initial rotating speed of the air conditioner during starting as the target rotating speed of the air conditioner.
If the operating temperature of the indoor fan is higher than the preset temperature, the operating temperature of the indoor fan of the air conditioner is higher than the preset safe operating temperature of the indoor fan of the air conditioner, namely the current rotating speed of the air conditioner is higher than the safe rotating speed limit value of the air conditioner, the current rotating speed of the air conditioner needs to be reduced to ensure the safe operation of the indoor fan of the air conditioner, the current rotating speed of the air conditioner is reduced, and the initial rotating speed of the air conditioner during starting is set as the target rotating speed of the air conditioner. For example, the preset safe operation temperature of the indoor fan of the air conditioner is 120 ℃, if the operation temperature of the indoor fan is equal to 120 ℃, the operation temperature of the indoor fan of the air conditioner exceeds the preset safe operation temperature of the indoor fan of the air conditioner, that is, the current rotation speed of the indoor fan of the air conditioner exceeds the safe rotation speed of the indoor fan of the air conditioner, and the current rotation speed of the air conditioner needs to be reduced to ensure the safe operation of the indoor fan of the air conditioner, the current rotation speed of the air conditioner is reduced, and the initial rotation speed of the air conditioner during the startup is set as the target rotation speed of the air conditioner.
