Abstract: A washing machine includes a dewatering shaft for rotating a washing tub, a drive shaft for rotating a pulsator in the washing tub, a coupler configured to move up and down along the dewatering shaft, a solenoid configured to move the coupler, a coupler guide configured to be rotated by contact with the coupler moving upward and to fix a position the coupler or guide the coupler to move to another position by contact with the coupler, a fixed core that surrounds the solenoid, and a moving core disposed at a perimeter of the coupler and configured to move the coupler by magnetic flux. The moving core is configured to, based on moving upward to the fixed core, maintain a gap defined between the moving core and the fixed core within a set range.

Abstract: A washing machine includes a washing tub rotatably disposed to accommodate laundry, a pulsator rotatably disposed in the washing tub, a drive shaft to rotate the pulsator, a dehydration shaft to be connected to the washing tub and through which the drive shaft passes, a solenoid to form a magnetic field when a current is applied, a fixing core to surround the solenoid, and a clutch to couple and uncouple the drive shaft and the dehydration shaft. The clutch includes an armature to be lifted by a magnetic force of the solenoid, and a clutch coupler to be elevated along the dehydration shaft, perform coupling between the drive shaft and the dehydration shaft in a first position, and perform uncoupling between the drive shaft and the dehydration shaft in a second position lifted from the first position. The shape of the armature provides a more uniform lifting force.
