Washing machine |
摘要 |
A washing machine capable of preventing damages of a clutch, a motor, etc., by sensing whether the clutch is normally operated. The clutch transmits a rotational force of the rotor to a dehydration shaft. The washing machine includes a washing shaft configured to rotate a pulsator, a dehydration shaft configured to rotate a drum disposed in a reservoir, a rotor coupled with the washing shaft and configured to transmit a rotational force to the washing shaft, a clutch configured to selectively transmit a rotational force of the rotor to the dehydration shaft a shielding member mounted to the clutch, a magnet provided at the rotor, and a magnetic sensor disposed to face the magnet. The magnetic sensor senses a position of the clutch as the shielding member shields a space between the magnet and the magnetic sensor by a motion of the clutch. |

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. |
