Washing machine and a control method of the same
A washing machine includes a case; a tub; a drum; a vibration sensor provided in the tub and configured to output a factor of a current vibration result for sensing a vibration value of the tub; a motor configured to drive the drum to process laundry; a motor control module configured to control a drum RPM to reflect a request RPM by controlling a current of the motor and output a current vibration inducing factor; an AI module configured to receive inputs of the current vibration result factor and the vibration inducing factor and output a compensating variable for proactively deal with a future vibration result that is expected based on a current laundry distribution state, in a dry-spin cycle; and a processor configured to perform a dry-spin cycle through centrifugal power of the drum by compensating the request RPM by reflecting the compensating variable in a vibration expectation section.
Washing machine and method for controlling the same
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.
METHOD FOR OPERATING AN AUTOMATIC WASHING MACHINE, AND AUTOMATIC WASHING MACHINE
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.

CLOTHING TREATMENT APPARATUS
A clothing treatment apparatus includes a tub for providing a space in which washing water is accommodated; a drum rotatably provided inside the tub; a motor for rotating the drum; and an induction heater which is arranged on the outer surface of the tub and which heats the drum. The motor can rotate the drum at a first rotational speed at which laundry accommodated inside the drum is rotated while adhered to the inner circumferential surface of the drum, during heating of the drum by the induction heater.

Method for detecting and correcting out of balance conditions in a washing machine appliance
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.
