Abstract: The traditional washing machine uses mechanical switch to control the imbalance of dehydration. The cost of this technical scheme is low, but the uncertainty of dehydration trajectory is prone to failure. In this paper, an acceleration sensor is proposed to detect the vibration amount of dehydration. According to the vibration amount, the dehydration mode and the maximum speed of dehydration are selected to ensure the safety and stability of the dehydration process.
