Technical Field

The invention belongs to the field of washing machines, and particularly relates to a washing machine.

Background

The washing machine is designed as a device for washing laundry by using electricity, and generally, the washing machine includes: a tub for holding washing water; a rotating tub rotatably installed inside the tub; a pulsator rotatably installed at the bottom of the rotary tub; a motor and a clutch configured to rotate the rotary tub and the pulsator; and the balance ring is arranged above the rotary barrel, and is used for supplementing weight when the rotary barrel rotates so as to keep balance. When the rotary tub and the pulsator are rotated in a state in which laundry and detergent are introduced into the rotary tub, the pulsator stirs wash water together with the laundry introduced into the rotary tub, thereby removing dirt from the laundry.

In order to increase the washing capacity of the washing machine, a larger rotary tub is required, i.e., the height or diameter of the rotary tub needs to be increased. If the rotary tub has a larger size, the tub accommodating the rotary tub and the cabinet accommodating the tub also need to be increased as the rotary tub is increased. The increase of the cabinet corresponding to the appearance of the washing machine is limited by the space of the area for installing the washing machine, the position for placing the washing machine in the house of a general user is limited, and the purpose of increasing the capacity of the washing tub by increasing the cabinet of the washing machine is unrealistic, for example, how to increase the capacity of the rotary tub becomes a big problem which troubles designers on the premise of not increasing the cabinet of the washing machine. The problem of dilatation has been solved in the birth of sclausura washing bucket, cancels or reduces the bucket, and rotatory bucket uses as the washing bucket that holds the washing water, disposes to sclausura washing bucket.

When the washing barrel rotates at a high speed, water in the washing barrel ascends to a water outlet arranged at the upper end along the wall of the washing barrel under the action of centrifugal force and is discharged, part of water continuously climbs to the joint of the balance ring and overflows out of the washing barrel from the joint of the balance ring, the time is long, the overflowing washing water can easily corrode the outer shell of the box body and other structures, and the short circuit of a circuit is easily caused.

Chinese utility model patent application No. 201721231925.2 discloses a washing machine, washing machine includes: a box body; a rotary tub rotatably provided in the cabinet; the balance ring is arranged at the upper end of the rotary barrel, a sealing groove is formed in the balance ring, and the upper edge of the rotary barrel is matched in the sealing groove; and the sealing element is arranged in the sealing groove and is abutted between the balance ring and the upper edge of the rotary barrel. But the sealing element is difficult to be installed in the sealing groove of the balance ring, so that the efficiency is low; in the process of installing the balance ring into the inner barrel body, the sealing element is easy to fall off from the sealing groove; the rotating barrel mouth part is not round in actual production, the size change range of the plastic balance ring is large, and the hidden trouble of leakage is caused.

The present invention has been made in view of this situation.
