Step motor control method for air conditioner as well as air conditioner

Abstract

The invention discloses a step motor control method and device for an air conditioner. The step motor control method for the air conditioner comprises the following steps of regulating an instruction according to an air guide plate to control a step motor to operate in an operation process of the air conditioner, and driving the air guide plate to rotate to the position; when the air guide plate rotates to the position, recording the operation step number, relative to a closed state of the air guide plate, of the step motor; and when the air conditioner is shut down, controlling the step motor to return to operate according to the operation step number, recorded at the last time, of the step motor, and enabling the air guide plate to return to the closed state. The step motor control method for the air conditioner shortens a return process of the step motor of the air conditioner, so that refrigerating/heating speed of the air conditioner is increased, and the service life of the step motor of the air conditioner is prolonged; and meanwhile, the step motor control method for the air conditioner further can reduce noises in a return process of the step motor, so that user experience is improved.

Description

Technical field [0001] The invention relates to the field of air conditioners, in particular to a stepping motor control method of an air conditioner and an air conditioner. Background technique [0002] The stepping motor is one of the important components of the air conditioner, and the actions of many components (such as the air deflector) in the existing air conditioner system are controlled by the stepping motor. [0003] In the prior art, the control method of the stepper motor that controls the action of the air deflector in the air conditioner when the air conditioner is turned on and off is as follows: (1) When the air conditioner was shut down normally last time, to ensure that the stepper motor controls the air deflector The accuracy of the board movement. When the air conditioner is turned on, the control system controls the stepping motor to adjust from the current position to the fully closed position before the control system controls the stepping motor to run from t...

Problems solved by technology

[0004] However, the above two methods of resetting the stepper motor in the prior art have the following defects: the resetting process is slow, which affects the cooling and heating speed of the air conditioner; In the process, every time the stepper motor completes the reset, it still needs to reset several steps excessively, and the stepper motor seriously affects the service life of the stepper motor
