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.
Claims18
A drum assembly in a washing machine comprising:
- a drum rotatable around an axis of rotation for holding laundry, the drum having a front wall with an opening therein for inserting and removing laundry, and a rear wall extending away from the front wall along the axis of rotation;
- a spider attached to an outside surface of the rear wall, the spider having a front surface adjacent to the outside surface of the rear wall and a rear surface extending away from the front surface along the axis of rotation;
- and
- a driving member coupled to the spider for rotating the drum,
- wherein the rear wall includes an expansion region unoccupied by the spider, the expansion region being protruded parallel to the axis of rotation away from the front wall, wherein at least a portion of the expansion region extends past all surfaces of the spider.
