Abstract:
1. A washing machine, comprising: a washing shaft; a dehydration shaft; a rotor, coupled to the washing shaft, to transmit a rotational force to the washing shaft; a clutch to selectively couple with the rotor, wherein said coupling is to transmit the rotational force of the rotor to the dehydration shaft; a shielding member mounted to the clutch; and a magnetism sensing apparatus including a metallic connection member having two ends bent in the same direction, and including a magnet and a magnetic sensor attached to opposite ends of the two ends of the metallic connection member with a predetermined distance therebetween, wherein the shielding member is configured to shield a space between the magnet and the magnetic sensor, and wherein the magnetic sensor senses a position of the clutch by sensing a magnetism increase between the two ends of the metallic connection member as the shielding member approaches to the magnetism sensing apparatus by a motion of the clutch.
