20090293204 | Washing machine and method of washing drum - Disclosed are a washing machine and a method of controlling the same. The washing machine includes a drum; a washing device to spray water to perform washing of an outer surface of the drum; and a control unit controlling the washing of the outer surface of the drum such that the washing of the outer surface of the drum is performed during a washing or rinsing cycle. The washing machine does not need to be disassembled to wash the drum and tub and thus is easily washed and has the ribs extended in a same direction of an extension direction of the flange shaft to increase the strength of the flange shaft and thus forms channels of water flowing on the flange shaft and reduces the remaining of contaminants on the flange shaft in the washing or rinsing cycle to enhance the washability of the flange shaft. | 12-03-2009 |
20100000574 | CONTROL METHOD OF WASHING MACHINE - A control method of a washing machine is capable of safely achieving a tub washing operation control with low power consumption. At the time of performing tub washing, water of which the amount is decided depending on a volume inside a drum and a volume inside a water tub is supplied to the water tub, and the rotation speed of the drum is controlled to be inversely proportional to the volume of the supplied water, thereby efficiently controlling a tub washing operation with low power consumption. Also, the rotation state of the drum is controlled, at the time of performing the tub washing, to maintain the temperature of a motor or a printed circuit board (PCB) to be a predetermined level or less, thereby safely controlling a tub washing operation with low power consumption. In addition, it is determined whether the revolutions per minute (RPM) of the drum rotating at the tub washing operation belong to a resonance band, and the RPM are controlled such that the RPM deviate from the resonance band, thereby achieving a tub washing operation procedure with small noise and vibration. | 01-07-2010 |

20140096570 | WASHING MACHINE - A washing machine including a drum capable of improving washing efficiency is provided. The washing machine includes a body, a tub provided at an inside the body to store wash water, a drum rotatably provided at an inner side of the tub to accommodate laundry, a driving apparatus to rotate the drum, protrusions that are formed of polygons having polygonal shapes and protruding inward from the drum, and a through-hole provided between adjacent protrusions to drain water. A protrusion having polygons generates frictional force between laundry and the drum, thereby increasing the washing power. The through-holes are uniformly located around the protrusion, thereby preventing a spin dry water bottleneck phenomenon that occurs when water from a spin dry is concentrated on a certain through-hole, and thus enhancing the spin dry efficiency. | 04-10-2014 |
