Washing machine and control method thereof

Abstract

The invention discloses a washing machine, which comprises:a tank, a washing tub and a motor, a detergent storage box and a detergent dispensing device, a turbidity sensor, a conductivity sensor, and a controller, wherein the detergent dispensing device is configured to store the detergent in the detergent box according to the detergent dosage signal The detergent is placed in the washing tub; the turbidity sensor is used for detecting the turbidity of the washing water in the washing tub after the pre-washing to obtain the first turbidity value, and detecting the turbidity of the washing water after the rinsing is suspended to obtain the second turbidity valuea conductivity sensor for detecting a conductivity value of the wash water after the rinsing pause; the controller is configured to perform pre-wash control, and generate a detergent delivery amount signal according to the first turbidity value, and according to the second turbidity value and the conductivity value Rinse control is performed. The washing machine of the invention can reduce the residue on the laundry, and the washing and rinsing are more clean. The invention also discloses a control method of a washing machine.

Description

technical field [0001] The invention belongs to the technical field of electric appliance manufacturing, and in particular relates to a washing machine control method and a washing machine adopting the method. Background technique [0002] With the advancement of technology and the needs of users for functions, washing machines are developing towards full intelligence. However, due to the different degrees of dirt of the clothes, in order to ensure clean washing, the required detergent, washing water and washing time should also be different. At present, most washing machines have made in-depth judgments on the degree of cleanliness of dirty clothes. However, due to the impact of factors such as the type of detergent input by the user, the amount of detergent used, the washing temperature, and the quality of the washing water, it can be judged that the stains on the clothes have been cleaned after washing.
