WASHING MACHINE AND CONTROL METHOD THEREOF

摘要

A washing machine and a control method thereof capable of determining whether a driving motor is locked. A pulsator is rotatably mounted in a spin basket, a driving motor generates rotational force, a clutch transmits the rotational force to the pulsator or the spin basket, a driving circuit supplies a driving current to the driving motor, and a control unit controls the driving circuit and the clutch so that the pulsator rotates in a forward or reverse direction and rotation of the spin basket is stopped in a washing or rinsing process. The control unit controls the driving circuit so that a motor lock detection current is supplied to the driving motor, and controls the clutch so that, if a rotating speed of the driving motor is less than a reference speed, the rotational force is transmitted only to the pulsator.

主权项

1. A washing machine comprising:
a spin basket rotatably mounted therein; a pulsator mounted in the spin basket in order to generate water current; a driving motor to generate rotational force; a clutch to transmit the rotational force to at least one of the pulsator and the spin basket; a driving circuit to supply a driving current to the driving motor; and a controller to control the driving circuit to supply a first current to the driving motor, reset the clutch if a rotating speed of the driving motor by supplying the first current is less than a reference speed.
