Abstract
A laundry processing apparatus includes an outer tub for accommodating washing water therein, an inner tub disposed inside the outer tub and containing laundry therein, a pulsator provided in a lower portion of the inner tub, a blade provided below the pulsator, a driving motor disposed outside the outer tub for rotating a washing shaft, a pulsator connecting shaft penetrating a lower side surface of the outer tub for rotating the pulsator, a blade connecting shaft which also penetrates a lower side surface of the outer tub for rotating the blade, and a gear module disposed outside the outer tub for transmitting a rotational force of the washing shaft to the pulsator connecting shaft and the blade connecting shaft respectively.
Claims7
A laundry washing apparatus comprising:
- an outer tub which accommodates washing water therein;
- an inner tub which is disposed inside the outer tub to contain laundry therein;
- a pulsator which is provided inside a lower portion of the inner tub;
- a blade which is provided below the pulsator;
- a pulsator connecting shaft which rotates the pulsator, and is disposed below the blade;
- a blade connecting shaft which rotates the blade independently from the pulsator;
- and
- a pulsator connection frame that connects an upper portion of the pulsator connecting shaft and the pulsator and that avoids a rotation orbit of the blade,
- wherein the pulsator connection frame comprises:
- a centrifugal extension portion that is extended in a centrifugal direction from a rotational axis of the pulsator connection frame;
- a plurality of upward extension portions that extends upwardly from a position away from an edge of the blade in the centrifugal direction and that connects the pulsator with the centrifugal extension portion;
- and
- a water flow through hole through which washing water below the blade penetrates the centrifugal extension portion in a vertical direction,
- wherein the centrifugal extension portion comprises a plurality of centrifugal extension portions,
- wherein the pulsator connection frame comprises a reinforcing portion that connects between the plurality of centrifugal extension portions and that is extended in a circumferential direction, and
- wherein each upward extension portion is connected to an edge of the centrifugal extension portion,
- wherein the centrifugal extension portion includes:
- a plurality of first centrifugal extension portions extended from the central portion of the pulsator connection frame to the reinforcing portion;
- and
- a plurality of second centrifugal extension portions extended from the reinforcing portion to a position spaced apart from the inner surface of the inner tub,
- wherein the number of the plurality of second centrifugal extension portions is less than the number of the plurality of first centrifugal extension portions,
- wherein the plurality of upward extension portions are connected to the plurality of second centrifugal extension portions, and
- wherein the number of the plurality of upward extension portion is less than the number of the plurality of first centrifugal extension portions.
