Abstract

A washing machine and a control method thereof are provided to reduce the whole dehydration time by shortening unbalance reduction control time to balance the laundry. A control method for reducing the unbalance generated due to the unbalanced of laundry in a washing machine equipped with a drum and a motor is as follows. The drum is accelerated to the predetermined speed so that the laundry adheres to the inner wall of the drum. The motor current is sensed while accelerating the drum. The unbalanced state of laundry is determined based on the sensed motor current. The speed of the drum is controlled according to the decision result. The speed of the drum includes a first rotation speed where the laundry does not adhere to the inner wall of the drum, a second rotation speed is greater than the first rotation speed so that the laundry adheres to the inner wall of the drum, and a third rotation speed between the first and the second rotation speed at which the laundry begins to adhere to the inner wall of the drum.

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...
