DETERGENT TYPE DETECTION METHOD, DETERGENT DOSAGE CONTROL METHOD AND WASHING MACHINE

Document Type and Number:

WIPO Patent Application WO/2019/001290

Kind Code:

A1

Abstract:

Disclosed are a detergent type detection method, a detergent dosage control method and a washing machine. The detergent type detection method comprises: determining N conductivity sections for N types of detergents; performing conductivity detection on detergents with unknown concentration, and marking the detected conductivity as d; determining the conductivity section within which the conductivity d falls; and identifying, according to the conductivity section within which the conductivity d falls, the type of the detergent with unknown concentration. The present invention uses conductivity to identify the type of detergent, and can directly determine the dosage of detergent using a look-up table method according to the type of detergent in combination with the weight of the clothes to be washed, not only accurately controlling the dosage of the detergent, but also making the control process more concise and the execution speed quicker as there is no need to convert the concentration of the detergent according to the conductivity. Furthermore, for a washing machine designed using the detergent dosage control method of the present invention, there is no need to dilute the detergent, simplifying the structural design and improving the production efficiency.
