Claims6
A washing machine comprising:
- an integrated tub/drum that includes a drum main body that has a cylindrical or truncated conical shape, is configured to store water, hold or accommodate laundry, and rotate, and a plurality of hollow lifters that protrude or extend outward from a circumferential surface of the drum main body and inward from the circumferential surface of the drum main body;
- a hollow rotary shaft coupled to and/or penetrating one surface of the drum main body;
- and
- a drain pipe in the integrated tub/drum through the hollow rotary shaft, configured to discharge water in the drum main body or the hollow lifters,
- wherein the plurality of hollow lifters includes a water collecting portion that extends or protrudes outward from the circumferential surface of the drum main body, and a lifting portion that extends or protrudes inward from the circumferential surface of the drum main body,
- wherein the water collecting portions are longer than the lifting portions, and the water collecting portions are closer to the drain pipe than the lifting portions,
- wherein the integrated tub/drum further includes a water collecting chamber that protrude or extend outward from a circumferential surface of the drum main body at an end of the drum main body nearest to the hollow rotary shaft, enclosing a circumferential surface of the drum main body and connecting the water collecting portions of the plurality of hollow lifters to each other, and
- wherein one end of the drain pipe extends into the water collecting chamber.
