A washing machine is provided that includes a washing tub, a driver to rotate the washing tub, a sensor to sense an operation of the washing machine, and at least one processor configured to obtain a weight of dry fabric of laundry in the washing tub, control the driver to rotate the washing tub at a speed within a first range, and obtain a first torque axis current of the driver. The at least one processor is further configured to, after supplying washing water to the washing tub, control the driver to rotate the washing tub at a speed within a second range and obtain a second torque axis current of the driver, and identify a material of the laundry by inputting at least one of the weight of the dry fabric, the first torque axis current, or the second torque axis current to a neural network model.

Washing machine and control method thereof

A washing machine includes a tub for accommodating a drum; a water supplier configured to supply water to the tub; a turbidity sensor configured to detect turbidity of water in the tub; a circulation bubble device configured to perform a circulation operation of circulating water in the tub and resupplying it to the tub or a bubble supply operation of generating bubbles and supplying them to the tub; and a controller configured to perform a first rinsing cycle when the turbidity of the water in the tub is higher than a first reference value, and control the water supplier so that water containing a softener is supplied to the tub and perform a second rinsing cycle by controlling the circulation bubble device to alternately perform the circulation operation and the bubble supply operation when the turbidity of the water in the tub is lower than the first reference value.
