Title:
DETERGENT CONSUMPTION CONTROL METHOD AND WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/001289
Kind Code:
A1
Abstract:
A detergent consumption control method and a washing machine, comprising: dividing up N concentration intervals according to detergent concentration from low to high, and correspondingly forming N conductivity intervals according to the N concentration intervals; detecting the conductivity of a detergent having an unknown concentration that is deposited in the washing equipment, and recording the detected conductivity as d; determining a conductivity interval where the conductivity d is located; and determining the consumption of the detergent having the unknown concentration by combing the weight of laundry according to the conductivity interval where the conductivity d is located. According to the described method, conductivity is used to reflect the concentration of a detergent, and the consumption of the detergent may be determined by using a look-up table by combing the weight of laundry according to the conductivity interval where the detergent is located, so that not only is the consumption of the detergent accurately controlled, but also controlling the flow is simpler and the execution speed is faster as the concentration of the detergent does not need to be converted according to the conductivity.
