Control method of washing machine

Abstract

A control method of a washing machine includes receiving purpose data of laundry, determining an operating course based on the purpose data of the laundry, and controlling washing of the laundry according to the determined operating course. The operating course is determined by confirming a material of laundry and predicting kind and amount of contamination of the laundry based on the purpose data of the laundry, thereby performing proper washing according to the purpose of the laundry whenever washing of the laundry is performed. Further, proper washing is performed according to the kind and amount of contamination of the laundry, thereby improving utility of the washing machine. Contamination degrees of wash water and rinse water during washing and rinsing cycles are detected, and a washing time and a frequency of times of the rinsing cycle are adjusted based on the contamination degrees, thereby increasing washing efficiency.

Description

technical field [0001] The invention relates to a control method of a washing machine for controlling the running process. Background technique [0002] In general, a washing machine is an apparatus that applies energy (eg, impact) to laundry to remove contaminants therefrom. The washing machine is classified into a pulsator washing machine, an agitator washing machine, and a drum type washing machine according to how energy is applied to laundry. [0003] The pulsator washing machine washes the laundry using the water flow obtained by rotating the disk-shaped pulsator, and the agitator washing machine uses a blade-like agitator protruding from the center of the washing tub to rotate left and right. The laundry is washed by an agitator, and the drum washing machine washes the laundry by tumbling in a rotating drum to apply impact to the laundry. [0004] The washing machine performs a washing cycle of washing laundry using water in which detergent is dissolved, a rinsing c...

AI Technical Summary

Problems solved by technology

[0005] Where problems such as wear and discoloration often occur during washing of laundry, such washing machines perform individual cycles regardless of the kind of contaminants and interaction with detergent, and thus cannot obtain effective washing of laundry

[0006] In addition, since the washing machine performs each cycle according to one operation course selected by the user from a plurality of preset operation courses, it may not be possible to wash the laundry according to the specific contamination characteristics of the laundry

[0007] Such washing machines cannot accurately identify the various types of pollutants that are combined and present in the laundry, thus reducing the washing efficiency and its usefulness
