Abstract: A method of controlling a washing machine. The washing machine includes a tub configured to receive water, a drum rotatably disposed in the tub, a volute pump including (i) an impeller configured to rotate in one or more directions to pump water discharged from the tub and (ii) a pump housing that defines a volute-shaped passage configured to guide water pumped by the impeller, and a circulating water supply device configured to supply water discharged from an outlet port of the volute pump into the drum. The method includes: supplying water and detergent into the tub; and rotating the impeller of the volute pump in a first direction to discharge a first amount of water from the volute pump, the first amount of water being less than a second amount of water discharged from the volute pump based on the impeller being rotated in a second direction.

Abstract: A method of controlling a washing machine, including: a first detection operation of acquiring an amount of laundry in a washing tub; selecting one of a plurality of washing courses based on the amount of laundry determined in the first detection operation; and performing the selected washing course. The plurality of washing courses includes a first washing course performing washing according to a first washing mode configured based on the amount of laundry and a second washing course performing washing according to a second washing mode configured based on the amount of the laundry and a state of the laundry. The second washing course includes a second detection operation of acquiring the state of the laundry by using a machine-learning network that processes an electrical current value applied to a motor for rotating the washing tub during an accelerated rotation of the washing tub.
