Abstract
Drum assembly, and method for fabricating the same is disclosed, for making a capacity larger and enhancing stiffness and strength. The drum assembly includes a drum for holding laundry, a connector attached to an outside surface of a bottom of the drum, and a driving member coupled to the connector for rotating the drum, wherein the bottom includes an expansion region unoccupied by the connector, the expansion region being protruded toward an outside of the drum, to expand a capacity of the drum. The method includes a first time pressing for pressing a plate for forming a bottom of a drum, for securing a space for expanding a capacity of the drum, and a second time pressing for forming a seat for attaching a connector connecting a driving member and the drum.
Claims61
A drum assembly in a washing machine comprising:
- a drum for holding laundry;
- a connector attached to an outside surface of a bottom of the drum;
- and
- a driving member coupled to the connector for rotating the drum,
- wherein the bottom includes an expansion region unoccupied by the connector, the expansion region being protruded toward an outside of the drum, to expand a capacity of the drum.
A drum assembly in a washing machine comprising:
- a drum for holding laundry, the drum having a bottom arranged close to an inside surface of a tub which encloses the drum for maximizing a capacity;
- a connector attached to an outside surface of the bottom of the drum;
- and
- a driving member passed through the tub, and coupled to the connector for rotating the drum,
- wherein the bottom includes;
- a region close to the tub, and
- a seat depressed in the region for inserting the connector therein, to prevent the connector from being brought into contact with an inside surface of the tub.
A drum assembly in a washing machine comprising:
- a drum for holding laundry;
- a spider attached to a bottom of the drum;
- and
- a driving member coupled to the spider with a shaft for rotating the drum,
- wherein the bottom of the drum includes;
- a radial shape of seat occupied by the connector, and
- an expansion region protruded toward an outside of the drum along an axis direction of the drum, to expand a capacity of the drum.
A method for fabricating a drum in a washing machine comprising:
- a first time pressing for pressing a plate for forming a bottom of a drum, for securing a space for expanding a capacity of the drum;
- and
- a second time pressing for forming a seat for attaching a connector connecting a driving member and the drum.
