A driving device for a washing machine includes: a shaft including an inner shaft and an outer shaft surrounding the inner shaft; a motor assembly including a stator, a rotor that surrounds the stator, a modulator that surrounds the rotor, and a magnetic gear rotating body that surrounds the modulator; a first fixation body that connects between the inner shaft and the magnetic gear rotating body; a second fixation body having one end connected to the stator and the other end connected to a tub; and an electronic clutch that disconnects the outer shat and the rotor or connects the inner shaft and the rotor according to an operation mode of the washing machine. The modulator adjusts a speed and torque of the magnetic gear rotating body. The driving device may make a motor drive area highly efficient and may reduce electric consumption.

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.

A sealing valve plug structure includes a valve plug column corresponding to the drain opening formed in the side wall of an inner drum, and a counterweight hinged to the upper end of the valve plug column. The sealing valve installation structure is installed on the side wall of the drum, and the reset spring is clamped between the sealing valve installation structure and the valve plug column. The counterweight is used to generate an action, under the action of centrifugal force, to open the drain opening, and the valve plug column is reset by the reset spring to make the valve plug block the drain opening, to thereby open and close the drain opening. A cleaning-free washing machine having an inner drum sealed by the sealing valve plug structure is also disclosed.

An inner door assembly for a drum washing machine includes an inner door internal shell formed of plastic and including a rim portion and a projecting portion projecting from the rim portion; and an inner door external shell formed of metal and including a rim portion and a projecting portion corresponding to the rim portion and the projecting portion of the inner door internal shell, wherein the inner door external shell is combined not to be separated from the inner door internal shell.

The invention provides an apparatus (8) for cleaning cloth which includes a body (10) with an aperture, a closure, which is engageable with the aperture, a tub (26) with an outer shell and a cylindrical Inner cavity which corresponds with the aperture, a drum (28), which is positioned inside the cylindrical inner cavity (54) and which includes a wall, with an inner surface, an outer surface and a plurality of perforations (62) in the wait, a base (64) and an opposing mouth (66) which registers with the aperture, a drive means (30) which is connected to or engaged with the drum and which allows rotational movement of the drum about an axis, a generator (32) and an electrical power supply (78), inside the body, wherein the power supply is adapted to provide pulsating electrical power to the generator and wherein the generator is actuable to produce pulses of microwave energy at least into part of the drum.

Disclosed is a drum washing machine, including: a drum configured in an outer tank and capable of rotating by using an inclination axis as center; a stirring body configured at a rear part of the drum and including main blades in contact with washings; a driving unit enabling the drum and the stirring body to rotate at different rotating speeds; and a water supply mechanism part configured to splash water to a surface of the stirring body. The water supply mechanism part includes a first water storage part capable of moving between a position in water soaked in the outer tank and a position higher than the water and storing water when soaked in water of the outer tank, and a first outflow port capable of enabling water stored in the first water storage part to flow out to the surface of the stirring body at an upper position.
