Abstract
Washing machine technology, in which an initial speed in a drainage process is determined after a rinsing mode is finished, and a laundry distributing operation is performed in which a rotational speed of the motor is maintained at the determined initial speed. The washing machine determines whether a degree of laundry distribution satisfies an allowable range by comparing information detected by a vibration sensor with previously stored reference information. The initial speed is determined to be a rotational speed of the motor at an intersection time point at which vibration of a fundamental wave and vibration of higher harmonics detected by the vibration sensor intersect with each other.
