Abstract: A method for washing laundry and a washing machine, in which balancing of the laundry load is effectively carried out. The method for washing includes supplying wash water mixed with a detergent, spinning or rinsing the laundry by rotating the washing machine drum in which the laundry is located, thereby causing the laundry to be repeatedly lifted within and then fall towards the bottom of the drum. The method further involves balancing the laundry by repeatedly accelerating and decelerating the drum. The wash water is then drained.

Abstract: A washing machine that calculates a temperature of a balancer to effectively control a motor and a method of controlling the washing machine are provided. The washing machine comprises a rotatable drum that receives laundry, a motor that rotates the drum, a balancer that is connected to the drum, the balancer changing a center of gravity of the drum, and a controller that rotates the motor at a constant rotational speed and then calculates a temperature of the balancer based on a period of a variation in rotational speed of the motor.

Abstract: A washing method and a washing machine are provided. Wash water is drained from a tub prior to initiating a main spinning process, and wash water is supplied into a drum to decrease the volume of the laundry which is increased by the draining. Therefore, it is possible to effectively reduce the volume of laundry and thus to improve the mobility of the laundry. Then, a main spinning process is performed by spinning the drum at high speed.

Abstract: A washing machine and a controlling method of the same are disclosed. A washing machine includes a cabinet (10) defining an exterior appearance thereof, a tub (20) provided in the cabinet (10), the tub (20) receiving wash water therein, a drum (30) rotatable inside the tub (20), the drum (30) receiving laundry therein, a plurality of sensor members (100,102,104,112,116,120,130) installed in at least one of the drum (30) and tub (20), each of the sensor members (100,102,104,112,116,120,130) sensing the distance between the drum (30) and the tub (20), and a control part controlling the drum (30) based on a sensing value sensed by the sensor members (100,102,104,112,116,120,130). An object of the present invention is to provide a washing machine having a secured tub (20) that is able to prevent collision between a drum (30) and the tub (20), and a controlling method thereof.
