  • Composite balance ring and washing machine
    Patent number: 10358759
    Abstract: The present disclosure discloses a composite balance ring and a washing machine. The balance ring is internally hollow to form a chamber. The chamber is horizontally provided with a partition plate which divides the chamber into upper and lower chambers. The upper and lower chambers communicate through an overflow structure and a backflow structure, and the chamber is filled with balancing liquid with a level close to the partition plate. During the dehydration process of the washing machine, the balancing liquid in the lower chamber overflows into the upper chamber by a low overflow speed through a narrow gap that forms the overflow structure, and the balancing liquid remaining in the lower chamber provided with a counterweight force in the inner tub, so that the increase of eccentric displacement of the inner tub due to eccentric flowing of the balancing liquid is avoided.
