Embodiment 1

[0039] Embodiment 1, the air deflector is arranged at the air outlet of the air conditioner, and plays the role of air guide when the air conditioner is running. When the air conditioner is not in operation, the air guide is closed to block the air outlet, which can play a role dust-proof effect, this embodiment proposes a control method for wind deflectors, such as figure 1 As shown, including a voltage control step, the voltage control step includes:

[0040] Detect the working voltage of the wind deflector drive motor;

[0041] Correcting the driving voltage pulse time m3 of the wind deflector driving motor according to the working voltage;

[0042] The driving motor is controlled according to the driving voltage pulse time m3 to drive the wind deflector to move.

[0043] When the air conditioner is powered on and running, the wind deflector drives the motor to drive the wind deflector to rotate. The resistance to the rotation of the air deflector is its load. If the resi...

Embodiment 2

[0077] Embodiment 2, this embodiment proposes an air conditioner, such as image 3 As shown, it includes the wind deflector 11, the wind deflector drive motor 12 and the controller (not shown in the figure because of the angle), the wind deflector is pivotally connected to the air outlet 13 of the casing, and the wind deflector is according to the first embodiment The recorded control method of the wind deflector controls the operation. For details, please refer to the description in Embodiment 1, which will not be repeated here.

Abstract

The invention discloses a method for controlling a wind deflector and an air conditioner, including a voltage control step, including: detecting the working voltage of the driving motor of the wind deflecting plate; and correcting the driving voltage pulse time m3 of the driving motor of the wind deflecting plate according to the working voltage; The driving motor is controlled according to the driving voltage pulse time m3 to drive the wind deflector to move. In the control method of the wind deflector of the present invention, by setting the voltage control step, the driving voltage pulse time of the wind deflector drive motor is corrected according to the working voltage of the wind deflector drive motor, which can ensure that when the voltage is unstable, especially when the voltage is low, It can provide sufficient torque for the wind deflector, and by adjusting the driving voltage pulse time of the drive motor of the wind deflector, the torque of the wind deflector can be kept constant, which solves the current technical problems of the wind deflector that cannot be closed and stalled.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a method for controlling an air deflector and an air conditioner. Background technique [0002] Most air conditioner wind deflectors are operated by stepping motors. The stepper motor controls the switching speed with the default fixed pulse number, and the switching amplitude operation is performed by setting the number of steps in advance, resulting in waste of switching time. There is an overstep when fully open or closed, which is equivalent to the stepping motor stalling and will generate noise. [0003] The Chinese patent application with the publication number CN 105757876 discloses a method and device for controlling the air deflector of an air conditioner. By detecting the operating current, when the current is not less than the set threshold, it is considered that the load of the motor has increased, and the corresponding judgment is that the air d...
