    Abstract: The present disclosure relates to a washing machine configured to rotate a cylindrical drum formed by processing a metal sheet about a horizontal axis. The drum includes a lifter, formed by processing the metal sheet, respectively provided at a plurality of points spaced along a circumferential direction, when viewed from a front side. The lifter includes a front lifter which is formed by protruding the metal sheet into the drum, and pressurized to be extended in a longitudinal direction of the drum, and a rear lifter disposed in a rear side of the front lifter. The rear lifter is disposed to form a certain phase angle with respect to the front lifter.

    Abstract: A front-loading washing machine and a control method therefor are disclosed. The control method includes: when a sensed amount of laundry in a drum is equal to or less than a preset amount, rubbing step at which the drum is rotated in both directions, wherein the rubbing step comprises: a first rotation step at which the drum is rotated in a first direction by a preset one-direction rotational angle; and a second rotation step at which the drum is rotated by the one-direction rotational angle in a second direction opposite to the first direction, and wherein the first rotation step and the second rotation step are performed alternately and repeatedly. Accordingly, it is possible to perform a washing motion which improves washing performance and reduces wear and tear of the laundry.
