Roller washing machine and unbalance detection method and device thereof

The invention belongs to the field of detection and control technologies of washing machines and provides a roller washing machine and an unbalance detection method and device of the roller washing machine. The method comprises the steps that when a roller operates at a low uniform velocity, the torque of the roller is detected, and the average value of torque ripple is acquired; afterwards, when the roller operates in a constant-acceleration mode, the torque ripple values of the roller are acquired in real time, and whether dynamic unbalance happens on the roller or not is judged according to the average value of torque ripple and the torque ripple values; if yes, the roller is controlled to stop accelerated operation, and whether the frequency of shake scattering operations executed by the roller is larger than a preset frequency value or not is judged; if yes, the roller is controlled to stop operation; if not, the roller is controlled to execute shake scattering operations and then operates at a low velocity, and static unbalance detection is performed on the roller during low-velocity operation of the roller; accordingly, there is no need to adopt sensors for unbalance detection, so that the cost and detection difficulty are lowered; besides, the problem that dynamic unbalance detection is performed during high-velocity operation of the roller, so that mechanical parts are collided and damaged is avoided.
