Embodiment 1

[0041] 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 shown, including the following steps:

[0042] The initialization step is to determine the driving voltage pulse time of the wind deflector driving motor, which is the first driving voltage pulse time;

[0043] The initialization step can be performed once every time the power is turned on. In order to prevent the waste of resources caused by calculating the first driving voltage pulse time every time the power is turned on, it is preferable to determine whether the air conditioner is turned on for the first time before the initialization step. When it is judged to be powered on for the first time, an ini...

Embodiment 2

[0072] Embodiment 2, this embodiment proposes an air conditioner, such as Figure 4 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 an air deflector control method and an air conditioner. The method comprises the following steps: an initialization step: determining the drive voltage pulse time of an air deflector drive motor as the first drive voltage pulse time; and a step of controlling an air deflector to act, namely controlling the drive motor to drive the air deflector to act according to the firstdrive voltage pulse time. According to the air deflector control method provided by the invention, the first drive voltage pulse time is determined in the initialization step, and the pulse time is that in the case of different working voltages of the drive motor, it can be guaranteed that enough torque is provided for wind deflectors of different weights, ie, according to the control method of the scheme, regardless of the dead weight change of the wind deflectors, how the voltage of the drive motor changes, by adjusting the drive voltage pulse time of the wind deflector drive motor, the torque of the wind deflectors is kept constant, and the technical problems that an existing wind deflector cannot be closed, blocked and the like are solved.

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 wind 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 wind deflector is judged accordingly. ...
