Water inflow control method and device for washing machine

Abstract

The invention discloses a water inflow control method and device for a washing machine. The water inflow control method for the washing machine includes the steps that S1, inflow water of the washing machine is controlled to be on an initial water level; S2, the washing machine is controlled to execute the water replenishing washing stage; S3, at the water replenishing washing stage, whether the water level of the washing machine is lower than the water replenishing water level or not is judged; S4, if the water level of the washing machine is lower than the water replenishing water level, the washing machine is controlled to replenish water till the water reaches the stop water level; S5, the third step and the fourth step are executed repeatedly till preset time is reached or water is not replenished. By the adoption of the water inflow control method and device for the washing machine, the initial water level, the water replenishing water level and the stop water level are set, the initial water inflow quantity and the water replenishing quantity can be reasonably distributed, the control accuracy of the water inflow quantity is improved, water inflow time is shortened, the effective washing time is guaranteed, energy is saved, emission is reduced, and the clothes washing effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a method and device for controlling water inflow of a washing machine. Background technique [0002] At present, during the water intake process of the existing drum washing machine, the water intake water level and the replenishment water level can be preset to control the water intake. First, the water is fed to the water level, and then the inner tub starts to rotate for washing. Due to the water absorption of the clothes, the water level will drop. When the water level drops to the replenishment water level, the replenishment operation can be performed until the replenishment reaches the water intake level. Repeat the hydration operation several times until there is no hydration. After the water intake process is completed, the washing machine enters a formal washing process. [0003] However, with the development of society, energy saving and consumption redu...

AI Technical Summary

Problems solved by technology

As a result, the pre-set water intake level becomes lower, resulting in less water intake, longer time for replenishment, and longer wash times, resulting in wasted energy

Although the water inflow process can be controlled by setting the maximum water inflow and replenishment time, this will lead to insufficient actual water inflow and affect the washing effect
