Abstract

Disclosed is a drum type washing machine, and more particularly, a tub of a drum type washing machine enabling to effectively drain water and foam in the tub. The present invention includes a tub body having a drum installed rotatably inside, a sump at a bottom of the tub body to store water or foam, a drain outlet at a bottom of the sump wherein the water or foam is discharged via the drain outlet, and a rib at one side of the sump to prevent the water or foam from deviating from the sump.

Claims

1. A tub of a drum type washing machine, comprising:

a tub body having a drum installed rotatably inside;

a sump at a bottom of the tub body to store water or foam;

a drain outlet at a bottom of the sump wherein the water or foam is discharged via the drain outlet; and

a rib at one side of the sump to prevent the water or foam from deviating from the sump.

2. The tub as claimed in claim 1, wherein the sump is expanded to increase a capacity of storing the water and foam therein.

3. The tub as claimed in claim 2, wherein the drain outlet is formed at an expanded portion of the sump.

4. The tub as claimed in claim 2, wherein the rib is formed at an edge top of the expanded sump to prevent the water or foam from deviating from the sump by a rotation of the drum.

5. The tub as claimed in claim 1, wherein the sump is expanded in a rotational direction of the drum on dewatering to increase a capacity of storing the water and foam therein.

6. The tub as claimed in claim 5, wherein the drain outlet is formed at an expanded portion of the sump.

7. The tub as claimed in claim 5, wherein the rib is formed at an edge top of the expanded sump to prevent the water or foam from deviating from the sump by a rotation of the drum.

8. A drum type washing machine, comprising:

a cabinet forming an exterior;

a drum in the cabinet to hold a laundry and a detergent therein;

a tub body having the drum installed rotatably inside;

a sump at a bottom of the tub body to store water or foam;

a drain outlet at a bottom of the sump wherein the water or foam is discharged via the drain outlet; and

a rib at one side of the sump to prevent the water or foam from deviating from the sump.

9. The drum type washing machine as claimed in claim 8, wherein the sump is expanded to increase a capacity of storing the water and foam therein.

10. The drum type washing machine as claimed in claim 9, wherein the drain outlet is formed at an expanded portion of the sump.

11. The drum type washing machine as claimed in claim 9, wherein the rib is formed at an edge top of the expanded sump to prevent the water or foam from deviating from the sump by a rotation of the drum.

12. The drum type washing machine as claimed in claim 8, wherein the sump is expanded in a rotational direction of the drum on dewatering to increase a capacity of storing the water and foam therein.

13. The drum type washing machine as claimed in claim 12, wherein the drain outlet is formed at an expanded portion of the sump.

14. The drum type washing machine as claimed in claim 12, wherein the rib is formed at an edge top of the expanded sump to prevent the water or foam from deviating from the sump by a rotation of the drum.
