Balance ring structure and washing machine with same

Technical Field

The utility model belongs to the household electrical appliances field, concretely relates to washing machine's balanced ring structure and have its washing machine.

Background

Washing machines are common household appliances for washing laundry. Generally, a washing machine includes a cabinet forming an external appearance of the washing machine, an outer tub in the cabinet for storing washing water, an inner tub rotatably installed in the outer tub, a pulsator rotatably installed at a bottom of the inner tub; and a motor and a clutch configured to rotatably drive the inner tub and the pulsator.

At present, conventional washing machines have at least two functions of washing and dehydrating. When washing, the clothes, detergent and water are put into the inner barrel, the motor drives the inner barrel to rotate, and the clothes, the inner barrel and the detergent water rub to remove stains on the clothes. When the inner tub rotates, if laundry is unevenly distributed but is accumulated at one side of the inner tub, vibration and noise may be generated due to eccentric rotation of the inner tub, and components such as the inner tub, the motor, and the like may be damaged. When dewatering, the motor drives the inner barrel to rotate at a high speed, if clothes are not uniformly distributed, the inner barrel cannot normally rotate due to the eccentricity of the inner barrel, and the outer barrel is subjected to heavy impact, so that the inner barrel, the outer barrel, the motor and other components are damaged.

Therefore, the washing machine is generally equipped with a balancer to stabilize the rotation of the inner tub by offsetting an unbalanced load generated in the inner tub.

The balance ring of the prior washing machine is generally disposed at the top of the inner tub, as shown in fig. 1, the average diameter of the balance ring 1 is inside the inner tub 2, i.e., (D1+ D2)/2 < D. Therefore, a user can clearly see the balance ring 1 when using the balance ring, the balance ring 1 is made of plastic materials, the user firstly sees the plastic parts, and the plastic materials are not smooth and bright as compared with the stainless steel parts and are not beautiful enough.

In view of the above, there is a need for a washing machine that overcomes the above-mentioned drawbacks, and it is therefore desirable to provide the present invention.
