  • Patent number: 8297083
    Abstract: Disclosed is a washing machine having ball balancers, which adjust a relation between a gap, between the inner wall of a racer of each of the ball balancers and balls, and viscous oil, so as to reduce the vibration and noise of the washing machine. Each of the ball balancers of the washing machine includes balls and viscous oil accommodated in a racer, and the viscosity of the viscous oil is varied in proportion to a gap between the racer and the balls. When the viscosity of the viscous oil is 1˜100 cSt, the gap is set to 0.5˜1.0 mm, when the viscosity of the viscous oil is 100˜380 cSt, the gap is set to 1.0˜2.0 mm, and when the viscosity of the viscous oil is 380˜1,000 cSt, the gap is set to 2.0˜3.0 mm. Thereby, the relation between the gap and the viscous oil is optimized, and the ball balancers effectively exhibit a balancing function and thus minimize the vibration and noise of the washing machine.
