And whether the user of the indoor unit of the air conditioner triggers the direct-blowing prevention key of the indoor unit of the air conditioner can be detected by detecting whether the indoor unit of the air conditioner receives the operation direct-blowing prevention mode instruction to obtain whether the user triggers the direct-blowing prevention key of the indoor unit of the air conditioner.

Referring to fig. 8, in the present embodiment, in step S704, the controlling the first air guiding plate 210 to rotate to a state of guiding the air flow to the lower side, and the controlling the second air guiding plate 220 to rotate includes:

in step S812, the first air guiding plate 210 is controlled to rotate to a state of guiding the air flow downward, and the second air guiding plate 220 is controlled to rotate to make the air outlet area equal to the first predetermined value.

Step S814, controlling the air conditioner indoor unit to operate for a preset duration.

After entering the anti-direct-blowing mode, the control method of the embodiment can control the first air deflector 210 and the second air deflector 220 to rotate according to the difference between the ambient temperature and the preset temperature, so as to forcibly control the first air deflector 210 to rotate to the state of guiding the air outlet flow to face downward before the air outlet area is adjusted, and control the second air deflector 220 to rotate so that the air outlet area is the first preset value, and operate for the preset time. Therefore, the control method can provide a buffering period for the user to enter the direct blowing prevention mode, and further improves the user experience.

It should be understood that, in the direct blowing prevention mode, the control method may set a plurality of predetermined values for the air outlet area in advance, and after entering the direct blowing prevention mode, control the rotation of the first air deflector 210 and the second air deflector 220 according to the difference between the ambient temperature and the predetermined temperature, so as to force the air conditioner indoor unit to adjust the air outlet area to a predetermined value at or close to the middle value among the plurality of predetermined values before adjusting the air outlet area, that is, control the air conditioner indoor unit to adjust the air outlet area to the first predetermined value to operate. At this time, the rate of the temperature drop of the indoor space is not too fast nor too slow, so that the indoor unit of the air conditioner is more suitable for the user when the normal cooling mode is switched to the blow-through prevention mode with the first predetermined value. Meanwhile, in the process of switching the indoor unit of the air conditioner from the direct blowing prevention mode with the first preset value to the direct blowing prevention mode with the air outlet area of other preset values, the value of the increase or decrease of the air outlet area cannot be very large, and a user can well adapt to the direct blowing prevention modes with different air outlet areas of the indoor unit of the air conditioner or well adapt to the switching of the indoor unit of the air conditioner among various direct blowing prevention modes, so that the user gradually adapts to the direct blowing prevention modes with various air outlet areas of the indoor unit of the air conditioner. Therefore, a buffering period for entering the direct blowing prevention mode from the common refrigeration mode can be provided for a user, and the user experience of the indoor unit of the air conditioner is further improved.

In addition, the preset duration can be preferably three minutes, so that the requirement that the user adapts to the direct-blowing prevention mode is met, the user does not experience that the buffering period is long, the current indoor space temperature cannot be immediately close to the set temperature and feels uncomfortable, and the user experience is guaranteed.

It can be understood that the corresponding relationship may be obtained through a plurality of tests by a person skilled in the art, that is, whether the preset air outlet area can reduce the preset difference to 0 within a certain time period is tested, and if not, the set air outlet area is replaced, and the preset difference is replaced after the preset air outlet area capable of reducing the preset difference to 0 is tested, and the test is repeated, so that the corresponding relationship between the preset difference and the preset area value of the air outlet area can be obtained.

In the present embodiment, the corresponding relationship represents that the preset area value decreases with a stepwise decrease or a continuous decrease of the preset difference value.

It should be understood that the stepwise decrease may be represented by the range of the preset difference value of the former whole being larger than the range of the preset difference value of the latter whole, and the continuous decrease may be represented by the range of the preset difference value of the former whole being larger than the range of the preset difference value of the latter whole. Moreover, the preset area value is reduced along with the step-type reduction or continuous reduction of the preset difference value, which shows that the smaller the difference value is, the lower the temperature reduction rate required by the user is, the smaller the required air outlet area is, and then the air conditioner indoor unit controls the first air deflector 210 and the second air deflector 220 according to the corresponding table to adjust the air outlet area, so that the air outlet area can be well adapted to the requirements of the user, and the user experience is ensured.
