Example one

As shown in Figure 1-3, this embodiment provides a washing machine, including

A washing bucket 1, which is a tub when washing;

The balance ring 2 is provided with an annular groove 202 opening downward, and the upper edge of the washing tub 1 extends into the annular groove 202;

The sealing structure 3 is wrapped around the upper edge of the washing tub 1 and is configured to prevent water from overflowing between the washing tub 1 and the balance ring 2.

In the above solution, the washing machine of this embodiment does not have an outer tub, and the washing tub 1 can be used as a water tub, that is, an inner tub with only dehydration holes in the upper part and no holes in the middle and lower parts. During dehydration, the washing water climbs up the drum wall to the dehydration hole under the action of centrifugal force, thereby discharging the washing bucket 1. Generally, a balance ring 2 is provided above the washing bucket 1 of the pulsator washing machine. Since the balance ring 2 and the washing bucket 1 are not integrally formed, they are installed together at a later stage, so they climb up along the bucket wall under the action of centrifugal force The water flow is easy to overflow through the installation gap between the washing tub 1 and the balance ring 2, and it is likely to splash around under the action of high-speed rotation. For a long time, it is easy to splash and corrode the washing machine cabinet or other parts, or cause a short circuit. The present invention is provided with a sealing structure 3 to prevent water from overflowing between the washing tub 1 and the balance ring 2. The sealing structure 3 is arranged between the washing tub 1 and the balance ring 2 to achieve a better sealing effect, and it is easier to fix the sealing structure 3. The effect is better than that provided outside the washing tub 1 or the balance ring 2. The annular groove 202 opens downward. After the balance ring 2 is installed, the upper part of the washing tub 1 extends into the inside of the annular groove 202. Under the action of gravity, the balance ring 2 will not easily escape from the washing bucket 1, Under the action of the groove 202, the movement of the balance ring 2 in the radial direction is also restricted. At this time, if the sealing structure 3 is a soft gasket, it is difficult to install and is inefficient if it is placed in the annular groove 202 of the balance ring 2. In the process of installing the balance ring 2 into the inner barrel, the seal is easily removed from the groove. In addition, in the actual production, the upper edge of the washing tub 1 is not round, and the size of the plastic balance ring 2 varies widely. There is still a hidden danger of leakage after the gasket is installed. The sealing structure 3 provided in the present application for the above defects is wrapped around the upper edge of the washing tub 1, which is convenient to install and has high efficiency; and in the process of installing the balance ring 2 on the upper edge of the washing tub 1, the sealing structure 3 is not easy to move from the ring shape. The groove 202 falls off; and because the sealing structure 3 is wrapped around the upper edge of the washing tub 1, the hidden danger of leakage caused by the roundness of the upper edge of the washing tub 1 and the large size range of the balance ring 2 can be avoided.

In a preferred embodiment, the seal lip 302 is disposed between the side wall of the annular seal groove 301 and the balance ring 2. In this embodiment, during the installation of the balance ring 2, the seal lip 302 and the ring of the balance ring 2 are annular. The grooves interfere with each other, further blocking the gap between the balance ring 2 and the upper edge of the washing bucket 1 due to the non-roundness of the mouth of the washing bucket 1 and the large size range of the balance ring 2, preventing leakage, which greatly enhances the seal. Effect, and convenient molding; and because the upper edge of the washing tub 1 is thin, it is more simple and convenient to install on the upper edge of the washing tub 1, without the blocking of the sealing lip 302 will not cause installation difficulties. In a more preferred embodiment, the sealing lip 302 is provided on a side wall of the annular sealing groove 301 on the inner peripheral wall side of the washing tub, and a further barrier-seal lip 302 is provided at a position where water is most likely to overflow Better results.
