Washing machine balancing ring, inner tub, and washing machine

Abstract

A washing machine balancing ring comprises a balancing ring body (2), wherein a ring-shaped rib (4) is arranged in the periphery of the balancing ring body (2), the balancing ring body (2) is connected to the ring-shaped rib (4), and multiple drainage holes (5) are disposed between the balancing ring body (2) and the ring-shaped rib (4). The ring-shaped rib (4) is connected to the balancing ring body (2) through a connecting structure, and the connecting structure is provided with multiple drainage holes (5). A washing machine inner tub provided with the washing machine balancing ring is also disclosed, wherein the balancing ring is mounted on the opening of the tub body (1), the ring-shaped rib (4) is fixedly connected to the upper end of the tub body (1), and the tub body (1) and the tub bottom (3) are each of a sealed structure. The washing machine inner tub can drain away water smoothly, the drainage is not affected by the balancing ring at the upper end, and can effectively prevent washing water from rising along the tub wall and overflowing from the drainage holes. The fixation strength between the inner tub and the balancing ring is higher, and when the washing machine performs dewatering, the deformation of the inner tub is smaller, thus reducing vibration noise during dewatering of the washing machine.
