A washing machine has a rotatable drum including a cylindrical wall and a base at one end on the cylindrical wall. The base includes a projecting member to space clothes in the drum from the base. At least one slot is in the base to enable passage of water into the drum. A tub includes a cylindrical wall and a base at one end of the cylindrical wall. The tub receives the rotatable drum within the cylindrical wall. The tub includes a water inlet in line with the at least one slot so that as the at least one slot is aligned with the water inlet, water is sprayed into the drum. A meshing arrangement is positioned between the drum base and the tub base to reduce a gap between the drum and tub and provide a forced passage maintaining the water at the inlet.

A lifter for a laundry treating apparatus includes a first member mounted at an inner side of a drum; and a second member mounted on the first member and protruded toward an inside of the drum, wherein the first member includes a hook protruded and formed along a circumference of the first member, at least part of which is disposed to cover an inner circumferential surface of the drum when inserted into a fastening hole of the drum and then slid in one direction; and a shield protruded and formed at an inner side of the first member and configured to completely cover the fastening hole when the hook is inserted into the fastening hole and then slid in one direction.

A method for controlling a laundry washing machine. The method includes: performing a tub loading process comprising operating supply valve(s) to provide a first volume of water through a detergent supply system and into a tub to fill the tub with wash liquid; performing a washing process comprising rotating a drum to agitate laundry in in the presence of the wash liquid; performing a static rinsing process comprising operating a pump to remove any free volume of wash liquid from the tub without rotating the drum; and performing one or more rinsing processes comprising: operating the supply valve(s) to provide a volume of clean rinse water to the tub, operating the pump to remove the rinse water from the drum, and operating the motor to spin the drum at high speed to extract rinse water from the laundry, while continuing to operate the pump.

A washing machine and method for operating a washing machine having a suds container for holding washing liquid, a non-ribbed drum provided with stamped portions rotatably mounted in the suds container for holding laundry, a motor for driving the drum, and a control device. During rotation of the drum in a subcritical rotational speed range, the method includes sampling a variable related to the drum or the motor over a predetermined period of time to determine time signals of the variable, executing a frequency analysis of the time signal of the variable to determine frequency components of the variable in a predetermined frequency range, summing the frequency components at predetermined frequencies of the predetermined frequency range, and detecting, depending on the sum of the summed up frequency components, whether a loading situation where laundry is sliding in the drum is present.

A drum-type washing apparatus includes: a housing including a door in a front thereof to be opened and closed; and a washing tub supported to spin inside the housing, having a cylindrical shape opened toward the door to accommodate laundry therein, and including a pattern on which a plurality of dewatering holes for discharging wash water are arranged on an inner circumferential surface thereof, the pattern including: a first pattern including an even area provided at least one side of a first dewatering hole along the inner circumferential surface, and a second pattern provided at least one side of a second dewatering hole different from the first dewatering hole along the inner circumferential surface and including an uneven area having lower flatness than the even area.
