摘要： A counterweight of washing machine, a washing machine and a counterweighting method for the washing machine relates to the technical field of washing machines. The technical solutions mainly adopted are as follows: the counterweight of washing machine includes at least one counterweight cavity and at least one pressured water structure; a water entering port for connecting a water entering pipeline and a water draining port for connecting a water draining pipeline are formed on a wall of each of the at least one counterweight cavity; the at least one water pressurizing structure is disposed in each of the at least one counterweight cavity, and is configured to enable water entering each of the at least one counterweight cavity to be in an air-free sealed cavity; the counterweight of washing machine is configured to be fixed on a water containing drum of the washing machine; and the washing machine comprises the counterweight of washing machine. The counterweight method for the washing machine is achieved by using the counterweight of washing machine to perform mass-adjustable counterweighting on the washing machine. The counterweight of washing machine is mainly configured to reduce vibration and nose of the washing machine in work, and reduce the production and transportation cost of the washing machine.

摘要： Systems and methods for predicting and preventing a cabinet strike event in a washing machine appliance are provided. An exemplary method includes ramping a target speed of a motor from a first speed to a second speed over a ramping period. The method includes computing an average deviation of an observed speed of the motor from the target speed over the ramping period. The method includes computing an average power consumption by the motor over the ramping period. The method includes determining whether both the average deviation is greater than a first threshold value and the average power consumption is greater than a second threshold value. The method includes rebalancing the load if both the average deviation is greater than a first threshold value and the average power consumption is greater than a second threshold value. The method includes performing one or more standard operations if both conditions are not satisfied.

摘要： A laundry treatment apparatus in which as an outer tub vibrates, a piston and a cylinder are relatively moved. When as the outer tub vibrates, the piston and the cylinder move relative to each other and a frictional member provides a frictional force between itself and the other one to attenuate vertical vibration of the outer tub. In particular, the piston and the cylinder are prevented from being separated from each other in the laundry treatment apparatus.

摘要： A dewatering machine including an electric motor for rotating a dewatering drum and a control part. When the dewatering drum starts to rotate, the control part measures a load of the washings in the dewatering drum. Then, the control part rotates the motor at a first rotating speed by controlling a duty ratio of a voltage applied to the motor and then to rotates the motor at a second rotating speed higher than the first rotating speed. When the motor accelerates to the first rotating speed, the control part acquires a reference duty ratio at timing determined according to the measured load. Next, within a specified period, the control part determines whether the washings in the dewatering drum are biased according to an index indicating the change between the duty ratio and the reference duty ratio.

摘要： A method of operating a laundry treating appliance includes controlling rotation of a drum during a cycle of operation by a controller communicably coupled to a motor, sending an excitation signal to a controller that randomly fluctuates an acceleration command to affect acceleration of the motor, determining, by the controller during excitation, one or more inputs sensed from the motor, and estimating with a parameter estimator parameter values of a laundry load in the drum based on the inputs. The cycle of operation can then be adjusted based on the estimated parameter values of the laundry load.

摘要： A method for controlling a washing machine configured to receive laundry and including a tub and a drum located in the tub includes rotating the drum at a water supply revolutions per minute (RPM), supplying wash water to the tub based on rotating the drum at the water supply RPM, accelerating rotation of the drum based on supplying wash water to the tub, sensing a first eccentric value of the drum based on accelerating the rotation of the drum, based on the first eccentric value, determining a rotational speed for rotating the drum, and rotating the drum at the rotational speed.

摘要： A washing machine includes a machine housing, a tub that is suspended on a plurality of support arms in the machine housing, and a washing drum that is rotatably mounted in the tub, at least one of the support arms being equipped with a force sensor, which generates a force measurement signal that is representative of the force acting upon the respective support arm. Moreover, the washing machine is equipped with a level sensor, which generates a level signal that is representative of the water level in the washing drum, and an electronic control unit that processes the force measurement signal and the level signal, and which is configured to control the sequence of a washing program of the washing machine in dependence on the force measurement signal and the level signal.
