Abstract: A drum washing machine, and a control method and a control apparatus for same are provided. The control method for the drum washing machine comprises the following steps: acquiring an average starting power of a drum in a starting process of the drum; acquiring a load range to which a current load of the drum belongs according to the average starting power; and setting a weighing protection velocity fluctuation threshold according to the load range to which the current load of the drum belongs. A value of the current load is obtained by using a correspondence between load with different weights and average starting powers. A weighing protection velocity fluctuation threshold is set according to the value of the current load to avoid the collision with the drum and non-dehydration in case of only one piece of clothing.

Abstract: An operation control method and system for a clothing treatment device having a drum and a motor is provided. Load inertia of the drum and a fluctuation parameter of the motor are obtained. Load eccentric mass of the clothing treatment device is obtained based on the load inertia, the fluctuation parameter, and predetermined relationship data that is obtained based on pre-stored load inertia, torque fluctuation and load eccentric mass. The fluctuation parameter can be a torque fluctuation parameter or a rotation speed fluctuation parameter. The clothing treatment device can be controlled according to the load eccentric mass to optimize washing operations. For example, clothing and/or inlet water amount can be timely adjusted according to the calculated load eccentric mass. Thus, the clothing treatment device is prevented from producing significant noise during operations, and the service life of the clothing treatment device can be prolonged.

Abstract: The present disclosure relates to a front-loading washing machine and an unbalance detection method and device thereof. The method comprises: when a drum operates at a low constant speed, detecting the torque of the drum and acquiring average torque values; when the roller operates at a constant acceleration speed, acquiring average torque values and a minimum value of the average torque values of the drum in real time; determining whether a difference between the average torque and the minimum value of the average torque values is greater than a preset unbalance threshold; and if so, determining that dynamic unbalance occurs on the drum; otherwise determining that no dynamic unbalance occurs on the drum. Because no sensor is needed for unbalance detection, cost and the detection difficulty are lowered, and damages to mechanical components due to collisions caused by dynamic unbalance when the drum operates at a high speed is avoided.
