20120159717 | CONTROL METHOD OF LAUNDRY MACHINE - Control methods of a laundry machine are disclosed. One of them is a control method of a laundry machine comprising a water supplying step configured to drive the drum of the machine in scrub motion when water is supplied to the tub of the machine. Another control method of the laundry machine comprising a washing cycle with at least one water supplying step configured to drive the drum in a predetermined time period after water supply to the tub starts or after the water level reaches a predetermined value. | 06-28-2012 |
20130111676 | WASHING MACHINE TO PRODUCE THREE-DIMENSIONAL MOTION - A method for driving a washing machine that includes a main body, a tub disposed within the main body, a main drum rotatably mounted in the tub, a sub drum mounted in the main drum to be relatively rotatable with respect to the main drum, a driving motor, and a control unit to control operations of the driving motor includes producing a three-dimensional motion of laundry in the washing machine by moving the laundry in a circumferential direction and an axial direction simultaneously by relative motions of the main drum and the sub drum to perform the washing process while supplying washing water and detergent. | 05-09-2013 |
20130118212 | WASHING MACHINE TO PRODUCE THREE-DIMENSIONAL MOTION - A washing machine includes a main body defining an outer appearance, a tub disposed within the main body, a main drum rotatably mounted in the tub, a sub drum mounted in the main drum to be relatively rotatable with respect to the main drum, an outer shaft for rotating the main drum, an inner shaft for rotating the sub drum, being disposed inside the outer shaft, and a driving motor having a stator, an outer rotor connected to the inner shaft that is rotatable outside the stator, and an inner rotor connected to the outer shaft that is rotatable inside the stator, wherein the driving motor independently drives the main drum and the sub drum. | 05-16-2013 |
20130118213 | WASHING MACHINE TO PRODUCE THREE-DIMENSIONAL MOTION - A washing machine includes a driving motor having a stator, an outer rotor connected to the inner shaft and rotatable outside the stator, and an inner rotor connected to the outer shaft and rotatable inside the stator. Stator slots, which are fixedly-installed as a coil are wound on stator teeth. The outer rotor and the inner rotor include rotor teeth, a permanent magnet and a bushing, spaced from an inner circumference of the stator and rotates centering around a rotor shaft by magnetic force. The rotor teeth includes a teeth extension portion extending from a side end of an outer circumference of the rotor teeth in a circumferential direction, a cut recess cut in a concaved manner from the outer circumference of the rotor teeth toward the center of the rotor shaft, and an insertion recess cut in a concaved manner in a radial direction from an inner circumference of the rotor teeth. | 05-16-2013 |
20130118214 | WASHING MACHINE TO PRODUCE THREE-DIMENSIONAL MOTION - A washing machine includes a main body defining an outer appearance, a tub disposed within the main body, a main drum rotatably mounted in the tub, and a sub drum mounted in the main drum to be relatively rotatable with respect to the main drum. The washing machine includes an outer shaft for rotating the main drum, an inner shaft for rotating the sub drum, being disposed inside the outer shaft, and a driving motor having a stator, an outer rotor connected to the inner shaft and rotatable outside the stator, and an inner rotor connected to the outer shaft and rotatable inside the stator. The washing machine also includes a spring washer inserted into a connection part of the outer shaft and the inner rotor that attenuates vibrations of the outer shaft to prevent noise and to prevent separation of the outer shaft due to the vibrations. | 05-16-2013 |
