Washing machine control method, device and washing machine

Abstract

The present invention discloses a method of controlling a washing apparatus and a washing machine, wherein the method comprises, after the user inputs the start instruction, the washing machine into the pre-wash phase, and acquires a calibration value of the turbidity and conductivity; When the prewash phase control turbidity sensor for detecting turbidity and conductivity of the liquid within the tube current; obtaining haze value according to the change in haze and turbidity calibration values ​​and parameters determined washed haze change value; parameters controlling a washing machine in accordance with the washing into the washing stage; when the end of the wash phase, rinse phase and into, the end of each rinsing liquid controlling the conductivity of the current sensor detects the inner cylinder; comparison to obtain the conductivity and conductivity change of the conductivity value according to the calibration value, and acquires the change and the ratio between the conductivity values ​​determined criterion, and determines whether the ratio is less than or equal to a preset threshold; if yes, exits the rinsing stage.The method can reduce or even eliminate residual detergent on the laundry.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine control method, device and washing machine. Background technique [0002] With the improvement of living conditions, the demand for user functions is also constantly improving, and the washing machine is moving towards full intelligence. At present, traditional washing machines generally set a fixed number of rinsing and washing times, or judge the washing time and rinsing times by detecting the turbidity value of the laundry water. For example, if the turbidity value of the laundry water is detected to be relatively high, the washing machine will Laundry is washed longer and rinsed more often. [0003] But there is a problem that, due to the different degree of dirtiness of the clothes, the detergent, water, and time needed to wash the clothes should not be the same. For example, down jackets in winter will be washed more than T-shirts in summer. The time is l...

[0003] But there is a problem that, due to the different degrees of dirtiness of the clothes, the detergent, water and time needed to wash the clothes should not be the same. For example, down jackets in winter will require less washing than T-shirts in summer. The time is long, the amount of detergent is large, and due to the influence of factors such as the type of detergent input by the user, the dosage, the washing temperature, and the water quality, it is not possible to judge whether the detergent on the clothes has been rinsed only by detecting the turbidity of the laundry water. Clean, for example, after many alkaline detergents are dissolved in water, the turbidity is very low, so the stains in the washed clothes may be washed, but there may still be a little detergent in the clothes. The detergent may cause damage to the user's skin, resulting in poor user experience
