BALANCE RING STRUCTURE AT INNER TUB BOTTOM

WIPO Patent Application WO/2018/099421

A1

Disclosed is a balance ring structure at the inner tub bottom, the balance ring structure comprising an inner tub bottom (1) and an inner tub bottom cover (2) mounted at the bottom of the inner tub bottom (1). The inner tub bottom (1) and the inner tub bottom cover (2) are connected in a sealing manner, and a sealed annular chamber (4) is formed therebetween. The annular chamber (4) is filled with a balance liquid. In the annular chamber (4), baffles distributed in a staggered manner are arranged on the inner tub bottom (1) and the inner tub bottom cover (2). A circulation channel for the balance liquid is formed between the adjacent baffles. The balance ring structure is simple, can be conveniently refitted onto an existing washing machine and makes full use of a space between the inner tub bottom (1) and the inner tub bottom cover (2), thereby improving the efficiency of use of a space inside the washing machine, and the baffles distributed in a staggered manner are arranged in the annular chamber (4) formed between the inner tub bottom (1) and the inner tub bottom cover (2), thus the flow speed of the balance liquid is effectively limited, and at the initial stage of dehydration of the washing machine, a better balance effect can be achieved.
