Dish washing machine

A dish washing machine comprising:

• a washing tub;
• a nozzle to spray washing water;
• a vane that linearly reciprocates in the washing tub and deflects the washing water sprayed from the nozzle as the vane linearly reciprocates;
• a driving source to generate power;
• an idle gear;
• a driving gear unit;
• a belt connected to the driving gear unit and the idle gear to rotate in a rotation direction via the power generated by the driving source transferred to the belt by the driving gear unit, to cause the vane to linearly reciprocate;
• and
• a direction changing member rotatably combined with the vane to rotate with respect to the vane so that, as the belt rotates in the rotation direction, the vane linearly reciprocates in a first direction until the direction changing member rotates with respect to the vane and thereby causes the vane to linearly reciprocate in a second direction opposite to the first direction.

A dish washing machine comprising:

• a nozzle to spray water;
• a vane to deflect the sprayed water;
• a belt;
• a gear coupled with the belt to transfer power generated by a motor to the belt to cause the belt to rotate in a rotation direction;
• and
• a direction changing member having a first portion combined with the vane so that the first portion is rotatable with respect to the vane, and a second portion fixed to, or integrated with, the belt,
• wherein the belt, the gear and the direction changing member operate together so that
• the vane linearly reciprocates together with the direction changing member in a first direction toward the gear due to the rotation of the belt in the rotation direction while the vane deflects the sprayed water, and,
• after the vane together with the direction changing member reach the gear due to the rotation of the belt in the rotation direction, the direction changing member traverses the gear which causes the first portion to rotate with respect to the vane, without the vane being rotated, to thereby cause the vane together with the direction changing member to linearly reciprocate away from the gear in a second direction opposite the first direction due to the rotation of the belt in the rotation direction while the vane deflects the spayed water.
