WASHING MACHINE HAVING BALL BALANCER

摘要

A washing machine having a ball balancer is provided to reduce noise and vibration of the washing machine by optimizing correlation of a gap between the inner wall of a race and a ball and viscosity of viscose oil. In a washing machine, a ball balancer(20) has a ball(22) and viscose oil in a race. The viscosity of viscose oil varies in proportion to a gap(L1+L2) between the race and the ball. If the viscosity of viscose oil is less than 100~380cSt, the gap between the race and the ball is 1~2mm. If the viscosity of viscose oil is less than 1~100cSt, the gap between the race and the ball is 0.5~1.0mm. If the viscosity of viscose oil is less than 380~1000cSt, the gap between the race and the ball is 2.0~3.0mm.
