BALL BALANCER AND WASHING MACHINE HAVING THE SAME

摘要

Disclosed is a ball balancer that increases a rate of balls in ball detention portions and restricts aggravation of unbalance caused by balls outside of the ball detention portions. When a rotation speed of a rotator is less than a first rotation speed, the ball detention portion allows the ball moved from a rolling face to be detained therein and to allow the ball therein to come into contact with the released ball outside thereof to prevent separation of the released ball from the rolling face. Anti-separation portions are provided to come into contact with the released balls outside of the ball detention portions to prevent separation of the released balls from the rolling face. When the rotation speed is greater than the first rotation speed, the ball detention portion allows separation of the ball therein to the rolling face by centrifugal force applied thereto.
