Wherein, when the stepping motor 13 rotates in the forward direction, the knob contact 1211 rotates toward the first fixed end 1213.
As shown in connection with fig. 3, an embodiment of the present disclosure provides a method for controlling an air deflector, including:
s210, the processor detects the current voltage value of the variable terminal.
S220, the processor determines a target voltage value of the variable terminal.
S240, the processor controls the stepping motor to rotate under the condition that the current voltage value is different from the target voltage value.
And S280, controlling the stepping motor to stop rotating by the processor under the condition that the current voltage value is the same as the target voltage value.
By adopting the method for controlling the air deflector provided by the embodiment of the disclosure, the stepping motor drives the knob contact of the slide rheostat and the air deflector to rotate, and the rotating angle of the knob contact corresponds to the rotating angle of the air deflector, so that the voltage value of the variable end corresponds to the angle of the air deflector. And detecting the current voltage value of the variable end to obtain the current angle of the air deflector. A target voltage value of the variable end corresponding to the target angle of the air deflector is determined. Under the condition that the current voltage value is different from the target voltage value, the air deflector is not at the target angle, and the stepping motor is controlled to drive the knob contact to rotate to change the current voltage value and drive the air deflector to rotate to change the current angle of the air deflector. And under the condition that the current voltage value is the same as the target voltage value, indicating that the air deflector is at the target angle, and controlling the stepping motor to stop rotating. And determining whether the air deflector is at a target angle or not and controlling the stepping motor through the current voltage value of the variable end of the sliding rheostat so as to improve the accuracy of controlling the rotation of the air deflector of the air conditioner.
Optionally, the determining, by the processor in step S220, the target voltage value of the variable terminal includes: the processor determines a target angle for the air deflection. The processor determines a target voltage value for the variable terminal based on the target angle. Thus, according to the target angle of opening the air deflector, the target voltage value corresponding to the variable end of the slide rheostat is determined. Under the condition that the current voltage value is different from the target voltage value, the stepping motor is controlled to rotate so that the current angle of the air deflector gradually reaches the target angle, and the accuracy of controlling the air deflector of the air conditioner to rotate is improved.
2-2 and 2-3, optionally, the processor determining the target voltage value of the variable terminal according to the target angle includes: u (U) t ＝(U V -U i )×θ t /θ m +U i . Wherein U is t For the target voltage value, U V For the supply voltage value, U i At minimum voltage value, θ t For the target angle, θ m Is the maximum angle. For the voltage divider circuit of FIG. 2-2, U i Is 0V. For the voltage divider circuits of FIGS. 2-3, U i ＝U V ×R d /(R m +R d ). Wherein R is d R is the resistance of the divider resistor m The maximum resistance of the sliding rheostat. Therefore, the target voltage value can be calculated according to the target angle of the air deflector, so that the accuracy of controlling the air deflector of the air conditioner to rotate is improved.
The two formulas for determining the target voltage value of the variable end are applicable to the situation that the rotation range of the knob contact of the slide rheostat is identical to the rotation range of the air deflector. That is, when the air deflector rotates to the maximum angle, the knob contact is positioned at the first fixed end, and the voltage value of the variable end is the power supply voltage value at the maximum. When the air deflector rotates to the minimum angle, the knob contact is positioned at the second fixed end, and the voltage value of the variable end is the minimum voltage value. When the voltage parameter is actually designed, certain deviation exists or the rotation ranges of the voltage parameter and the rotation range are not identical, and only the voltage parameter in the formula is required to be corrected.
Alternatively, the larger the current voltage value of the variable end, the larger the current angle of the air deflector. When the stepping motor rotates forward, the angle of the air deflector is increased. Thus, the direction of rotation of the stepper motor is synchronized with the current voltage value and the trend of the current angle. I.e. when rotating in the forward direction, the current voltage value and the current angle are increased; upon reverse rotation, the current voltage value and the current angle decrease. And judging the magnitude relation between the current angle and the target angle according to the magnitude relation between the current voltage value and the target voltage value. The current voltage value and the current angle are increased by controlling the stepping motor to rotate positively, the current voltage value and the current angle are reduced by rotating reversely, the current voltage value is adjusted to the target voltage value, and the current angle is adjusted to the target angle, so that the accuracy of controlling the air deflector of the air conditioner to rotate is improved.
As shown in connection with fig. 4, another method for controlling an air deflection is provided in an embodiment of the present disclosure, including:
and S200, initializing the air deflector by the processor.
S210, the processor detects the current voltage value of the variable terminal.
S220, the processor determines a target voltage value of the variable terminal.
S230, the processor judges whether the current voltage value is the same as the target voltage value. If yes, go to step S280. If not, step S241 is performed.
S241, the processor judges whether the current voltage value is greater than the target voltage value. If yes, go to step S242. If not, step S243 is performed.
S242, the processor controls the stepping motor to reversely rotate, and the step S210 is returned.
S243, the processor controls the stepper motor to rotate in the forward direction, and returns to step S210.
S280, the processor controls the stepping motor to stop rotating.
By adopting the method for controlling the air deflector, the rotating direction of the stepping motor can be determined according to the current voltage value and the target voltage value. The current voltage value and the current angle are increased by controlling the stepping motor to rotate positively, the current voltage value and the current angle are reduced by rotating reversely, the current voltage value is adjusted to the target voltage value, and the current angle is adjusted to the target angle, so that the accuracy of controlling the air deflector of the air conditioner to rotate is improved.
Optionally, the initializing the air deflector by the processor in step S200 includes: the processor finds a reference position for the deflector. In the case of finding the reference position, the processor detects the reference voltage value of the variable terminal. And the processor determines the relation between the angle of the air deflector and the voltage value of the variable end according to the reference position and the reference voltage value. Therefore, the relation between the angle and the voltage value of the variable end at the initial time of the air deflector can be determined, and the error between the angle and the voltage value in the rotation process of the air deflector is reduced, so that the rotation accuracy of the air deflector of the air conditioner is improved.
The reference position of the air deflector is the position when the air deflector resets. The reference position is divided into the following two types according to the design of the air conditioner structure: when the stepping motor rotates reversely, the angle of the air deflector is always 0 degrees, and the air deflector is in a closed state. Or when the stepping motor rotates forwards, the angle of the air deflector is always the maximum angle, and the air deflector is in a fully-opened state. When the reference position of the air deflector is found, the processor controls the stepping motor to stop rotating.
As shown in connection with fig. 5, another method for controlling an air deflection is provided in an embodiment of the present disclosure, including:
s210, the processor detects the current voltage value of the variable terminal.
S220, the processor determines a target voltage value of the variable terminal.
S240, the processor controls the stepping motor to rotate under the condition that the current voltage value is different from the target voltage value.
S250, the processor detects the current voltage value of the variable terminal again.
S260, the processor determines the difference between the current voltage value and the previous voltage value.
And S270, when the sign of the difference value of the voltage values is opposite to the rotation direction of the stepping motor, the processor controls the stepping motor to stop rotating, prompts the air deflector to rotate abnormally and finishes the control.
And S280, controlling the stepping motor to stop rotating by the processor under the condition that the current voltage value is the same as the target voltage value.
By adopting the method for controlling the air deflector provided by the embodiment of the disclosure, whether the rotating direction of the stepping motor is abnormal or not can be judged according to the voltage values detected twice before and after the rotating process of the stepping motor. When the rotation direction of the stepping motor is opposite to the expected direction, the fault of the stepping motor or the control circuit is indicated, and the air deflector is damaged when the stepping motor or the control circuit continues to operate. At the moment, the stepping motor is controlled to stop rotating, the air deflector is prompted to rotate abnormally, a user is informed of maintenance, and the air deflector is prevented from being damaged.
Alternatively, in the case where the sign of the difference in voltage values is positive and the direction in which the rotation of the stepping motor is controlled is reverse, the processor determines that the sign of the difference in voltage values is opposite to the direction in which the stepping motor rotates. Or, in the case that the sign of the difference in voltage values is negative and the direction in which the rotation of the stepping motor is controlled is positive, the processor determines that the sign of the difference in voltage values is opposite to the direction in which the stepping motor rotates. Therefore, through the direction relation between the sign of the difference value of the preset voltage value and the signal for controlling the rotation of the stepping motor, whether the rotation process of the stepping motor is abnormal or not can be judged conveniently, and the damage of the stepping motor is avoided.

And S271, when the absolute value of the difference value of the voltage values is larger than the difference value threshold value, the processor controls the stepping motor to stop rotating and prompts the air deflector to rotate abnormally, and the control is finished.
And S280, controlling the stepping motor to stop rotating by the processor under the condition that the current voltage value is the same as the target voltage value.
By adopting the method for controlling the air deflector provided by the embodiment of the disclosure, whether the rotating speed of the stepping motor is abnormal or not can be judged according to the voltage values detected twice before and after the rotating process of the stepping motor. When the rotating speed of the stepping motor exceeds the expected maximum speed, the stepping motor is indicated to have a fault, and the stepping motor and the air deflector are damaged due to the continuous operation. At the moment, the stepping motor is controlled to stop rotating, the air deflector is prompted to rotate abnormally, a user is informed of maintenance, and the air deflector is prevented from being damaged.
As shown in fig. 2-2 and fig. 2-3, the absolute value of the difference in the voltage values in step S271 is greater than the difference threshold, which is reflected in that the speed of rotation of the stepping motor exceeds the expected maximum speed, or in that the angle of rotation of the stepping motor and/or the air deflector within a certain time exceeds the expected maximum angle. The relation between the rotating angle of the air deflector and the voltage value of the variable end is as follows: Δθ= (U) 2 -U 1 )/(U V -U i )×θ m . Wherein delta theta is the rotation angle, U 2 At the current voltageValue U 1 For the previous voltage value, U V For the supply voltage value, U i At minimum voltage value, θ m Is the maximum angle. For the voltage divider circuit of FIG. 2-2, U i Is 0V. For the voltage divider circuits of FIGS. 2-3, U i ＝U V ×R d /(R m +R d ). Wherein R is d R is the resistance of the divider resistor m The maximum resistance of the sliding rheostat.
As shown in connection with fig. 7, another method for controlling an air deflection is provided in an embodiment of the present disclosure, including:

S250, the processor detects the current voltage value of the variable terminal again.
S260, the processor determines the difference between the current voltage value and the previous voltage value.
And S272, when the difference value of the voltage values is not zero, the processor prompts the air deflector to rotate abnormally.
By adopting the method for controlling the air deflector provided by the embodiment of the disclosure, whether the stepping motor continues to rotate can be judged according to the voltage values detected twice before and after under the condition that the stepping motor stops rotating.
