Patent ID: 8381343

Claim:
A method of controlling a laundry disentangling process in a washing machine, which includes a rotation drum containing laundry and a motor rotating the rotation drum to disentangle tangled laundry, the method comprising: (a) rotating the motor to one direction between a forward direction and a reverse direction; (b) detecting an rpm of the motor while rotating the motor at a first acceleration rate if the motor starts rotating in the one direction; (c) determining whether the rpm of the motor reaches a first rpm, which is set in advance, by comparing the detected rpm of the motor with the first rpm; (d) detecting an rpm of the motor while rotating the motor at a second acceleration rate lower than the first acceleration rate if determined that the rpm of the motor reaches the first rpm, (e) determining whether the rpm of the motor reaches a second rpm, which is set in advance, by comparing the detected rpm of the motor with the second rpm; (f) determining whether a first time, which is set in advance, elapses by counting the amount of time for the motor being rotated in the one direction if determined that the rpm of the motor reaches the second rpm; (g) stopping the rotation of the motor during a second time shorter than the first time if determined that the first time elapses; and (h) rotating the motor to an opposite direction after rotating the motor in the forward or reverse direction, wherein an operation including from (b) to (g) is performed to disentangle the laundry inside the rotation drum if the motor starts rotating to the opposite direction.
