    Abstract: Disclosed is a method of controlling a washing machine having a tub for containing water, a drum rotatably provided in the tub, at least one nozzle disposed in front of the drum to spray water toward the drum, a washing motor configured to rotate the drum, and a circulation pump configured to circulate water discharged from the tub to the at least one nozzle, the method including: a step (a) of supplying water with detergent into the tub to a first water level; a step (b) of operating the circulation pump at a first speed such that the washing motor is repeatedly accelerated and braked while the circulation pump is operating at the first speed, causing laundry in the drum to be stuck to an inner circumferential surface of the drum in response to the acceleration of the washing motor and causing the laundry to fall from the inner circumferential surface of the drum in response to the deceleration of the washing motor, wherein the first speed is set within a range in which the water discharged from the circulation pump is not allowed to reach the at least one nozzle or, even if the water reaches the at least one nozzle, the sprayed water is not allowed to reach an inner circumferential surface of the drum; a step (c) of supplying water into the tub such that a level of water in the tub rises from the first water level to a second water level; and a step (d) of repeating acceleration and deceleration of the washing motor such that the circulation pump is accelerated in response to the acceleration of the washing moto, and the circulation pump is decelerated in response to the deceleration of the washing motor.

    Abstract: Disclosed is a washing machine comprising: a tub configured to contain water; a drum rotatably provided in the tub; at least one nozzle configured to spray water into the drum; a washing motor configured to rotate the drum; a circulation pump having a circulation pump motor and configured to pump water discharged from the tub to the at least one nozzle; and a processor configured to alternatively repeat acceleration and deceleration of the washing motor such that the washing motor is accelerated to make laundry in the drum rotate along with the drum while stuck to the drum owing to a centrifugal force, and the washing motor is decelerated to make the laundry separated from the drum; and operate the circulation pump motor to spray water through the at least one nozzle, wherein the circulation pump motor is accelerated and decelerated. The acceleration and deceleration of the circulation pump motor is performed in response to the acceleration of the washing motor and the braking of the washing motor, respectively. The circulation pump motor is a variable speed motor whose rotation speed is controllable, and the respective acceleration and deceleration of the circulation pump motor is performed with a certain gradient.

    Abstract: Disclosed is an artificial intelligence laundry treatment apparatus including a washing tub (4) configured to receive laundry, the washing tub being configured to be rotatable, a motor (9) configured to rotate the washing tub, a controller (60) configured to control the motor such that the washing tub is accelerated to a predetermined target speed at an acceleration gradient of 1.5 to 2.5 rpm/s within a range within which the laundry moves in the washing tub, and a current sensing unit (75) configured to sense current of the motor, wherein the controller is configured to obtain at least one of laundry weight or laundry quality from output of an output layer of an artificial neural network pre-trained based on machine learning using a current value sensed by the current sensing unit during accelerated rotation of the washing tub as input of an input layer of the artificial neural network.

    Abstract: The present invention relates to a washing machine and a control method of washing machine. The control method of washing machine includes: a first detection step of acquiring amount of laundry accommodated in a washing tub (4); a first washing step of performing washing based on a first laundry amount, when the first laundry amount acquired in the first detection step is equal to or larger than a preset first threshold value; a second detection step of, after the first washing step, acquiring the laundry amount accommodated in the washing tub by an output of an output layer of an artificial neural network while using a current value input to a motor (9) for rotating the washing tub during an accelerated rotation of the washing tub as an input data of an input layer of the artificial neural network previously learned by machine learning; and a second washing step of performing washing based on a second laundry amount, when the second laundry amount acquired in the second detection step is smaller than the first threshold value.
