US 11,149,376 B2 · Washing machine for adjusting operation based on injected detergent and method for controlling the same

Abstract

A washing machine capable of operating in an IoT environment through a 5G communication network and estimating the type and amount of injected detergent through a neural network model created according to machine learning, and a method of controlling the washing machine, are provided. The washing machine may include a first tub into which laundry is loaded, a water supplier configured to supply washing water to the first tub, a detergent detection sensor configured to detect first conductivity and first turbidity of the washing water, and a processor configured to determine a washing cycle of the washing machine based on detected information.

Claims20

Dependent claims

A washing machine comprising:

a first tub into which laundry is loaded;
a water supplier configured to supply washing water to the first tub;
a detergent detection sensor configured to detect a first conductivity and a first turbidity of the washing water after the washing water is supplied to the first tub;
and
a processor configured to determine a first washing cycle for the washing machine based on an amount of laundry loaded into the first tub,
wherein the processor is further configured to determine a type and amount of detergent injected in the washing water based on the detected first conductivity and first turbidity of the washing water, and determine a second washing cycle for the washing machine based on the determined type and amount of the detergent.
