In the above-mentioned solution, the washing machine of the present embodiment has no outer tub, and the washing tub 1 may be used as a water tub, that is, the inner tub 2 having only the dewatering holes in the upper portion and no holes in the middle and lower portions. During dehydration, the washing water ascends to the dehydration hole along the tub wall under the action of centrifugal force, thereby being discharged out of the washing tub 1. Generally, the balance ring 2 is arranged above the washing tub 1 of the pulsator washing machine, and because the balance ring 2 and the washing tub 1 are not integrally formed and are installed together at a later stage, water flow climbing upwards along the tub wall under the action of centrifugal force easily overflows through an installation gap between the washing tub 1 and the balance ring 2, and is likely to splash around under the action of high-speed rotation, so that the washing machine box or other parts are easily corroded by splashing for a long time, or a circuit short circuit is caused. The present invention provides a sealing structure 3 to prevent water from overflowing between the washing tub 1 and the balancing ring 2.
Further, the sealing structure 3 is disposed between the washing tub 1 and the balancing ring 2.

Further, the installation portion 201 includes an annular protrusion protruding radially from the sidewall of the balance ring 2, the fitting portion 101 includes an annular groove matching the shape of the annular protrusion, and the sealing structure 3 is disposed between the annular protrusion and the annular groove.
In the above scheme, the annular bulge is arranged to facilitate the installation of the balance ring 2. Of course, it is also possible to select an inwardly recessed concave portion as the mounting portion 201 on the sidewall of the balance ring 2, but the provision of the concave portion may affect the size and strength of the balance ring 2, and may reduce the balance effect, so it is preferable in this application that the mounting portion 201 includes an annular protrusion protruding from the sidewall of the balance ring 2.
Further, the washing tub 1 further includes a water blocking portion 102 disposed below the annular groove and configured to reduce a gap between the washing tub 1 and the balance ring 2 to block water, a water collecting chamber 103 is formed between the washing tub 1 and the water blocking portion 102 and the balance ring 2, and the water collecting chamber 103 is configured to collect rising water.
In the above scheme, the washing tub 1 further includes a water blocking portion 102, the water blocking portion 102 reduces a gap between the washing tub 1 and the balance ring 2, and when the water flow rises to the front of the water blocking portion 102, a part of the water is blocked from reaching the annular groove and overflowing the washing tub 1 through the annular groove, so that the sealing pressure of the sealing structure 3 is reduced. The water collection chamber 103 reduces the gap between the washing tub 1 and the balance ring 2 due to the presence of the water guard 102, so that a greater pressure is required when water passes through the water guard 102, thus collecting most of the water.
Further, the washing machine further comprises a water drainage structure, the water drainage structure comprises a dehydration water channel which is arranged on the outer wall of the washing barrel 1, communicated with the washing barrel 1 and used for discharging water thrown out by the washing barrel 1, and the water inlet end of the dehydration water channel is arranged above the washing barrel 1.
Further, the water inlet end is arranged on the water collecting cavity 103 below the water retaining part 102.
In the above scheme, the water inlet end is arranged on the water collecting cavity 103, and water with increased pressure in the water collecting cavity 103 is easier to enter the dehydration water channel from the water inlet end and is discharged.
Further, the water blocking portion 102 is a constricted portion formed by being retracted inward from the outer side of the washing tub 1.
Furthermore, the upper end of the necking part extends towards the outer periphery to form a supporting part for supporting the mounting part 201 of the balance ring 2, the supporting part extends upwards to form an accommodating part surrounding the mounting part 201 of the balance ring 2, and the upper end of the accommodating part is folded inwards to form a fixing part for fixing the mounting part 201 of the balance ring 2.
Further, the supporting portion, the accommodating portion and the fixing portion together form an annular groove which is opened inwards, and preferably, all corners formed by the necking portion and the annular groove are rounded.
