Drum type washing machine having ball balancers and controlling method of the same

摘要

Disclosed herein are a drum type washing machine (1) having ball balancers (40) and a controlling method of the same that are capable of reducing spin-drying time. The drum type washing machine having ball balancers (40) according to the present invention includes a rotary tub (20) having the ball balancers (40) mounted therein, a wash motor (100) to rotate the rotary tub (20), and a controller (200) to detect the eccentricity amount of the rotary tub (20) while controlling the rotary tub (20) to be rotated at a first rotation speed, and, when the rotation speed of the rotary tub reaches a second rotation speed, to control the rotary tub (20), such that the rotary tub (20) is decelerated to a third rotation speed and a drainage process is carried out.
