Description

Balance structure for washing machine and washing machine

Technical Field

The utility model relates to the technical field of washing machines, in particular to a balance structure for a washing machine and the washing machine.

Background

During the dewatering process of the washing machine, the laundry always generates an unbalanced distribution in the inner tub due to the randomness of the laundry distribution, which is commonly referred to as an eccentric load. When the inner barrel rotates at a high speed, the centrifugal force generated by the eccentric load can lead the inner barrel to vibrate violently, so that the inner barrel is easy to collide with the shell of the washing machine, thereby greatly reducing the service life of the washing machine.

The most common eccentric deviation correction mode in the market at present is as follows: through fixing the balancing device on the inner barrel (also called as balancing ring or balancing ring), during dehydration, the balancing device rotates along with the inner barrel, liquid brine filled in the balancing device can automatically flow to one side opposite to the eccentric load of clothes, so that the eccentric amount of the inner barrel is adjusted, the eccentric amount is reduced to be extremely low, and the automatic deviation correcting function is realized. The specific structure of the balancing device is shown in the patent number ZL200620019010.0 (the grant publication number CN 2900587Y) of the Chinese utility model 'washing machine balancing device', because the brine in the balancing device is sealed in the balancing device during production, the weight of the brine cannot be changed, and the excessive or small weight of the brine in the balancing device is not beneficial to balancing for different washing machines.

The balance device can form balance water flow at the upper part of the water storage cavity, the bottom of the balance water flow reaches the water outlet along with the increase of water quantity, and the water quantity entering from the water inlet is directly discharged from the water outlet, so that a relatively stable water flow is obtained in the balance ring, and a stable balance effect is achieved. However, this balancing device has the following limitations: because only the upper part of the annular water storage cavity of the balancing device is provided with the water inlet hole and the lower part is provided with the water outlet hole, and parts for opening and closing the water inlet hole and the water outlet hole are not arranged, water in the annular water storage cavity easily flows out of the water outlet hole automatically in the washing process of the washing machine, and water flow with enough weight in the annular water storage cavity is difficult to ensure, so that the running balance of the washing machine cannot be ensured.
