Noise reduction method of air conditioning movement mechanism

Abstract

The invention discloses a noise reduction method of an air conditioning movement mechanism. The noise reduction method of the air conditioning movement mechanism includes: obtaining gravity resistance torque borne by a drive wheel of the air conditioning movement mechanism at different positions on a motion trail; figuring out frequency of pulses sent by a stepping motor according to the gravity resistance torque when the stepping motor provides the gravity resistance torque; generating a torque frequency characteristic curve according to the gravity resistance torque and the pulse frequency; controlling the stepping motor according to the torque frequency characteristic curve, and completing uniform motion control for the air conditioning movement mechanism. The noise reduction method of the air conditioning movement mechanism controls the air conditioning movement mechanism according to the gravity resistance torque borne by the drive wheel of the air conditioning movement mechanism at the different positions on the motion trail, can achieve uniform motion for the air conditioning movement mechanism during the running process, and thereby achieves low vibration and low noise effects.

Description

technical field [0001] The invention relates to the technical field of air conditioner noise reduction processing, and more specifically, relates to a noise reduction method for an air conditioner movement mechanism. Background technique [0002] At present, the air conditioner movement mechanism includes panels, wind deflectors and the like. Most air conditioner movement mechanisms use stepping motors to achieve their predetermined functions, some are driven by a single motor, and some are driven synchronously by dual motors, but there is a problem in all of them: the single pulse frequency drive method. That is to say, the torque provided by the motor is constant during operation, but the force received by the moving mechanism at different points on its motion trajectory is constantly changing, which will cause the moving mechanism to not be in the same position during operation. The acceleration state is in the deceleration state, and the movement is not stable, which le...

That is to say, the torque provided by the motor is constant during operation, but the force received by the moving mechanism at different points on its motion trajectory is constantly changing, which will cause the moving mechanism to not be in the same position during operation. The acceleration state is in the deceleration state, and the movement is not stable, resulting in a large vibration and noise of the operating mechanism, which affects the noise reduction quality of the indoor air conditioner
