Abstract

Disclosed herein are a washing machine that is capable of maintaining the balanced state of laundry to more smoothly perform a spin-drying operation and a control method thereof. The control method of the washing machine including a drum to receive laundry and a motor to rotate the drum to reduce unbalance generated due to the nonuniform distribution of the laundry, includes wrapping the laundry by accelerating the drum such that the laundry sticks to an inner wall of the drum, detecting motor current during the wrapping of the laundry, determining an unbalanced state of the laundry based on the detected motor current, and controlling speed of the drum based on a result of the determination.

Description

technical field [0001] The present invention relates to a washing machine and a control method thereof, and more particularly, to a washing machine capable of maintaining a balanced state of laundry to more smoothly perform a spin-drying operation and a control method thereof. Background technique [0002] Generally, a washing machine (commonly, a drum type washing machine) is a machine that includes a sink for containing water (washing or rinsing water); a cylindrical drum rotatably mounted in a tub for containing laundry; and a motor for generating a driving force required to rotate the drum to wash the laundry by raising or dropping the laundry in the drum along an inner wall of the drum during rotation of the drum. [0003] A washing machine that removes dirt from clothes by using water (especially, wash water) that contains dissolved detergent, using water that does not contain detergent (especially, rinse water) to remove foam or residue from clothes Laundry washing i...
