Description
Technical Field

Background
At present, home washing machines are mainly pulsator type washing machines and drum type washing machines. The spin-drying speed and time of the pulsator washing machine are fixed before rinsing. If the washing barrel has large eccentricity, the washing barrel can impact a control rod, so that the mode of rinsing once and washing uniformly again is added for dewatering. If the drum washing machine is allowed to be eccentric, the rotating speed and the time of dehydration are also fixed, and the rotating speed cannot exceed the rotating speed of final dehydration. When large eccentricity is detected, dehydration before rinsing can be finished in a speed reduction mode, the dehydration time is different due to the eccentricity detection and uniform distribution time, and the effective dehydration time is unchanged.
In summary, the spin speed and the spin time before rinsing of the conventional washing machine are not changed by the degree of contamination of the laundry and the residual amount of the detergent. If the dehydration mode is changed to be controllable, the dehydration time or the rotation speed is reduced when the clothes are cleaner and the residual amount of the detergent is less, otherwise, the dehydration time or the rotation speed is increased, and the optimal matching of energy consumption and cleaning is achieved.
