Washing machine

A washing machine, comprising:

• a cabinet;
• an outer tub located in the cabinet, the outer tub being provided to accommodate wash water therein;
• an inner tub located in the outer tub, the inner tub being provided to accommodate laundry therein;
• an outer shaft configured to rotate the inner tub, the outer shaft having a hollow portion therein;
• a pulsator rotatably disposed in the inner tub;
• an inner shaft passing through the hollow portion of the outer shaft, the inner shaft configured to rotate the pulsator;
• a clutch configured to selectively transmit rotation of the inner shaft to the outer shaft;
• a solenoid configured to generate a magnetic field when a current is applied to the solenoid, the solenoid being radially spaced apart from the outer shaft;
• a bearing configured to rotatably support the outer shaft, the bearing being located at an upper side of the solenoid;
• and
• a bearing housing configured to receive the bearing and the solenoid therein, the bearing housing including a fixing core located alongside the solenoid,
• wherein the clutch comprises:
• a clutch coupler movable along the outer shaft between a first position and a second positon elevated above the first position, the clutch coupler connecting the outer shaft to the inner shaft when the clutch coupler is in the first positon, and the clutch coupler disconnecting the outer shaft from the inner shaft when the clutch coupler is in the second positon;
• and
• an armature fixed to the clutch coupler, the armature being movable by the solenoid to thereby move the clutch coupler from the first position to the second position, the armature comprising:
• a core inner portion located between the solenoid and the outer shaft when the clutch coupler is in the second position;
• and
• a core base extending radially outwardly from the core inner portion.

• a motor having a rotor;
• a rotor hub connecting the rotor to the inner shaft;
• a clutch configured to selectively transmit rotation of the inner shaft to the outer shaft;
• and
• a solenoid configured to generate a magnetic field when a current is applied to the solenoid, the solenoid being radially spaced apart from the outer shaft,
• wherein the clutch comprises:
• a clutch coupler movable along the outer shaft between a first position and a second positon elevated above the first position, the clutch coupler being engaged with the rotor hub to connect the outer shaft to the inner shaft when the clutch coupler is in the first positon, and the clutch coupler being separated from the rotor hub to disconnect the outer shaft from the inner shaft when the clutch coupler is in the second positon;
• and
• an armature fixed to the clutch coupler, the armature being movable by the solenoid to thereby move the clutch coupler from the first position to the second position, the armature comprising:
• a core inner portion;
• and
• a core base extending radially outwardly from the core inner portion.
