Abstract
A washing machine with a vibration reducing apparatus is capable of reducing a tub by use of the gyroscopic effect. If the drum is rotated in an imbalanced state where the laundry is positioned at a side of the drum without being uniformly distributed, a biased force is applied to a rotary shaft, and the drum performs an eccentric motion, causing vibration of the tub. The vibration of the tub is increased when the drum rotates at a high speed. The washing machine measures vibration of the tub at the high speed, and generates a vibration restraining force, thereby preventing the vibration from being transmitted to the outside due to a reaction force. The efficiency in reducing the excessive vibration of the tub is enhanced, so that the interval between the tub and the frame is reduced, thereby increasing the capacity of the washing machine.
