Description
Technical Field
The invention belongs to the technical field of washing machine dehydration, and particularly relates to a dehydration performance optimization method of a drum washing machine based on a dehydration curve.
Background
At the present stage, due to the fact that the requirement of external sales is met, corresponding water content can be difficultly achieved in a load dehydration stage aiming at individual water absorption, water carrying dehydration is easy to occur in the process, and when the gap between an inner barrel and an outer barrel is small, water rings are easy to generate, and drainage of a drainage pump is influenced. This affects the wash performance of the process, making it difficult to achieve a satisfactory process. Not only influences the user experience of the client, but also reduces the guarantee degree of the product. At present, a scheme exists in the market, namely judging after the rotation speed is increased to the high rotation speed, if the water is dehydrated, the rotation speed is reduced to a certain rotation speed and is maintained for a period of time, and the rotation speed is increased to the highest rotation speed.
To a certain extent, the problem of dehydration with water is solved. However, under the condition of a large load which is easy to absorb water and a small gap between the inner barrel and the outer barrel, the discharged water still has high rotating speed and cannot be discharged, so that dewatering with water is formed, and the water content is large. Meanwhile, when the rotation speed is reduced to a low rotation speed, if the maintaining time is short, the effect is low; if the maintaining time is long, the dehydration time is too long, the duration of the program and the electricity consumption are affected, and the energy efficiency is low on a star level.
