Abstract
The invention provides an eccentric size recognition method of a roller washing machine. The roller washing machine comprises an inner motor. The eccentric size recognition method includes the following steps that firstly, a motor is accelerated to target rotation speed, and after the target rotation speed is reached, and constant-speed control is conducted; secondly, after the target rotation speed is reached, actual rotation speed data of the motor starts to be recorded; thirdly, with one circle of rotation of the roller as one period, the maximum value of rotation speeds of the motor in multiple periods is calculated; fourthly, rotation difference values obtained in the continuous periods are processed, the maximum value and the minimum value of the deviation degree are eliminated, and the average value of remaining data is obtained; fifthly, the average value serves as an evaluation criterion of a current eccentric program of the roller washing machine. The eccentric degree existing before high-speed dewatering can be recognized, and accordingly whether dewatering is conducted or whether the maximum rotation speed of dewatering is limited is determined. Thus, it can be guaranteed that dewatering can be conducted in a safe eccentric range, and dewatering performance is improved. Vibration, displacement and noise caused by large eccentric degree can be effectively reduced..
