Clutch assembly and washing machine having the same

A washing machine comprising:

• a cabinet;
• a tub disposed within the cabinet, to store wash water;
• a rotating tub rotatably disposed within the tub;
• a pulsator rotatably disposed within the rotating tub;
• a motor disposed beneath the tub, to provide power for rotation of the rotating tub and the pulsator;
• and
• a clutch assembly disposed between the motor and the rotating tub,
• wherein the clutch assembly comprises
• a clutch coupling movable vertically between upper and lower positions to transmit the power from the motor to at least one of the rotating tub and the pulsator, and
• a clutch boss disposed beneath the clutch coupling such that the clutch boss is separated from the clutch coupling when the clutch coupling moves upwardly to the upper position, while being coupled to the clutch coupling when the clutch coupling moves downwardly to the lower position.

A clutch assembly comprising:

• first and second rotating shafts;
• a clutch boss connected to the first rotating shaft, to rotate together with the first rotating shaft;
• a clutch coupling coupled to the second rotating shaft, to rotate together with the second rotating shaft, the clutch coupling being vertically movable between upper and lower positions;
• and
• a clutch lever to selectively pivotally move the coupling lever, the clutch lever being pivotally movable between a first position, at which the clutch lever contacts the coupling lever, to press the coupling lever, and a second position, at which the clutch lever is spaced apart from the coupling lever.
