Description

Dehydration control method for optimizing deviation correcting action of roller

Technical Field

The invention belongs to the technical field of drum washing machines, and particularly relates to a dehydration control method for optimizing a drum deviation correcting action.

Background

There are some small and relatively water-absorbent loads on the market. Including bath clothes, infant clothes, jeans with velvet, etc., especially in summer, the user has less clothes washed each time, resulting in the appearance of only one or two clothes in the tub that are easily absorbed in water. Under the working condition, large eccentricity is easy to form, meanwhile, the structure of the washing machine cabinet exists during house decoration, so that the washing machine body can be designed in the direction of being thin, and the diameter of the inner barrel is increased. In this case, dehydration becomes difficult if the above problems occur.

At present, all products are continuously improved in the aspect, most of the products shake and scatter clothes by means of forward and reverse rotation of the inner barrel before dehydration, the clothes are hopefully uniformly distributed in the barrel, and the eccentricity in the barrel is reduced. The method can finish the deviation rectifying effect aiming at most loads at present, but when one piece of jeans with velvet and cotton infant clothes is used, the deviation rectifying action is difficult to finish the shaking effect because the clothes have the characteristics of strong water absorbability and easy shrinkage into a group. Meanwhile, when multiple loads of different materials are met, individual loads are extruded at one corner, and shake-out cannot be completed. The specific disadvantages are as follows:

1. the eccentric amount can not be effectively reduced when large eccentricity is formed under the full-load working condition;

2. the probability of reaching the highest rotation speed during dehydration cannot be guaranteed;

3. if large eccentricity is formed, the electric quantity and time loss are caused by the constant deviation correction;

4. the large eccentricity and high rotation speed can cause poor user experience and risk in program verification;

5. failure to properly dehydrate can result in too high a water content, affecting the customer experience.

The dewatering control method for optimizing the deviation correcting action of the roller includes judging the limit value of the machine body in the limit state. The small pre-dewatering is added once under the limit value to finish pre-dewatering once, and a part of water is thrown out of clothes which are easy to absorb water in the barrel, so that the load becomes easier to shake off while the eccentricity in the barrel is reduced, and the dewatering is finished in cooperation with the follow-up shaking-off action.
