A washing machine and 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 an open or closed loop control device, wherein the method has a step for rearranging the laundry in the drum. The drum is caused to execute a right-left motion by means of the motor so as to cause a rocking motion of the laundry at a rocking frequency, the predetermined rocking amplitude of which is adjusted such that a laundry fall is implemented in which the laundry falls from a first region of the drum into a second region of the drum.

The present invention relates to a washing machine comprising an outer tub containing water, and an inner tub disposed in the outer tub to accommodate laundry and rotated about a horizontal axis. The washing machine includes: a motor for providing rotational force; an outer shaft that has a first hollow, and rotates the inner tub; an inner shaft disposed in the first hollow and rotated by the motor; a pulsator disposed in the inner tub and coupled with the inner shaft; a planetary gear train for transmitting rotational force of the motor; a carrier mover which has an outer circumferential surface that is spline-coupled to an inner circumferential surface of the outer shaft, and an inner circumferential surface that is screwed with an outer circumferential surface of the clutch carrier; and a stopper restricting movement of the carrier mover, thereby achieving various washing modes with a simple mechanism by rotating the inner tub and the pulsator.

Disclosed herein is a washing apparatus includes a drum, a pulsator, a drum drive motor rotates the drum in a first direction or a second direction, a pulsator drive motor rotates the pulsator in the first direction or the second direction, and a controller controls the drum drive motor to rotate the drum in the first direction and to rotate the drum in the second direction when an operation period expires. When a drum drive current value is greater than a first reference current value during the first direction rotation of the drum, the controller controls the drum drive motor so that the drum drive motor stops rotating the drum in the first direction. When the operation period expires the controller controls the drum drive motor so that the drum is rotated in the second direction.
