A washing machine and method for operating a washing machine having a suds container for holding water, a non-ribbed drum rotatably mounted in the suds container for holding laundry, a motor for driving the drum, and an open or closed loop control device. The method allows the execution of a washing program (Wp) having a washing phase (Wa) and/or at least one rinsing phase (Sp), and includes feeding water into the suds container in a first region of the drum in at least one of these phases (Wa, Sp) up to a predetermined water level (h) that is selected such that the laundry floats in the water, and rotating the drum at a predetermined rotational speed such that water is released from a second region of the drum and falls onto the laundry.

A method of controlling a washing machine of the present invention includes the steps of: (a) supplying detergent contained in a dispenser together with water into an inner tub; (b) operating a pump to transfer the water supplied together with the detergent to a plurality of nozzles disposed above the inner tub; and (c) further supplying water into the inner tub, operating the pump while the water is being supplied, and rotating the inner tub so that laundry contained in the inner tub adheres to an inner surface of the inner tub by centrifugal force during the operation of the pump.

A washing machine includes a water storage tank, a vibration sensor provided to the water storage tank, a washing tub rotatably disposed in the water storage tank and configured to accommodate laundry therein, a motor configured to rotate the washing tub, and a controller. The controller is configured to: measure an unbalance (UB) value based on rotating the washing tub during a dewatering stroke; control the motor to stop rotating the washing tub based on the UB value exceeding an allowable UB value included in a preset UB table; measure a dewatering time of the laundry and a vibration value during the dewatering stroke using the vibration sensor; and change the allowable UB value included in the preset UB table based on the dewatering time and the vibration value.

A washing machine and method for operating a washing machine having a suds container and a non-ribbed drum. During rotation of the drum in a subcritical rotational speed range, the method includes determining an average value, a minimum, and a maximum of an oscillation of a physical variable relating to the drum or the motor, forming an overall average value from the determined average values, subtracting the overall average value formed from the corresponding minimum determined per oscillation and the corresponding maximum determined per oscillation to calculate a maximum value and a minimum value per oscillation, respectively. In each case an amount is formed from the respective calculated maximum value and an amount is formed from the respective calculated minimum value, a standard deviation from the amounts is determined, and a loading situation where laundry is rolling in the drum is determined based on the determined standard deviation.

The invention relates to a method for operating a washing machine having a suds container for holding washing liquid, a non-ribbed drum rotatably mounted in the suds container for holding laundry, a motor for driving the drum, and a control device, wherein the method comprises a step for detecting when laundry is sliding and/or rolling, comprising, while rotating the drum, sampling a variable related to a torque of the motor or a rotational speed of the drum over a predetermined period of time; and determining whether the laundry is sliding and/or rolling in the drum based on the variable sampled over the period of time.

The invention further relates to a corresponding washing machine.

A method of operating a washing appliance includes obtaining images of a wash chamber using a camera assembly operating at a frame rate equivalent to the basket speed. The one or more images are analyzed, e.g., using a machine learning image recognition process, to determine a cloth coverage ratio of the load of clothes in the wash basket. The cloth coverage ratio is compared to a predetermined coverage threshold for reducing out of balance conditions. Specifically, if the cloth coverage area is greater than the threshold, the wash basket may be ramped up to a hold or plaster speed. By contrast, if the cloth coverage area is less than the threshold, the basket speed may be maintained or lowered to permit the clothes to redistribute before ramping to the hold or plaster speed.

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.

Disclosed is a method of controlling laundry treating apparatus including supplying power to a driving unit configured to rotate a drum, an input unit configured to input a control command and a communication unit configured to receive a remote control command transmitted from a remote control device, setting a remote control mode so as to operate the driving unit if the communication unit receives the remote control command, and executing a standby operation so as to cut off power supply to the driving unit and to maintain power supplied to the communication unit, when the remote control mode is set.
