Abstract
A method of controlling a laundry treatment device includes introducing washing water into a tub of the laundry treatment device, identifying first turbidity information on the washing water after the washing water is introduced into the tub, identifying a type of detergent based on the identified first turbidity information, and controlling a washing stroke according to the type of the detergent.
Claims12
A laundry treatment device comprising:
- a tub configured to receive laundry;
- a water supply unit configured to supply washing water to the tub;
- a sensor unit configured to sense turbidity of the washing water introduced into the tub;
- and
- a processor configured to control the laundry treatment device according to a type of detergent that is identified based on first turbidity information on the washing water,
- wherein the first turbidity information is measured in a first time period, through the sensor unit, after the washing water is introduced into the tub,
- wherein the processor is configured to control a washing stroke according to the type of the detergent that is identified based on the first turbidity information on the washing water,
- wherein the first turbidity information includes a variation in turbidity value,
- wherein the processor is configured to:
- based on a first degree of change of the turbidity value within the first time period, identify the type of detergent to be a liquid detergent, and
- based on a second degree of change of the turbidity value within the first time period, identify the type of detergent to be a powder detergent, and
- wherein the first degree of change is greater than the second degree of change.
