Abstract

A dishwasher includes an improved structure to inhibit leakage of water. The dishwasher includes a main body and a tub inside the main body to form a washing space. The tub includes an upper panel, a lower panel, and a middle panel, and the tub is provided with a seaming portion between the upper panel and the middle panel, and between the middle panel and the lower panel. A door is configured to open and close the tub, and a bracket is coupled along an inner surface of the tub to form an accommodation space between the tub and the bracket. A seal is mounted in the accommodation space to provide a seal between the tub and the door, and a mounting member is arranged on the seaming portion to mount the seal in the accommodation space.

First claim

What is claimed is:

1. A dishwasher comprising:
a main body;
a tub in the main body and configured to form a washing space, the tub having an opening and having at least two panels with a seam between the at least two panels;
a door configured to open and close the opening in the tub;
a bracket coupled to an inner surface of the tub to form an accommodation space between the tub and the bracket;
a seal disposed in the accommodation space and configured to provide a seal between the tub and the door; and
a mount on the seam in the tub to mount the seal in the accommodation space.

2. The dishwasher of claim 1 , wherein
the tub further comprises a bracket coupler configured to protrude from the tub at a position adjacent to the door to couple to the bracket to be coupled thereto.

3. The dishwasher of claim 2 , wherein
the bracket coupler is formed by a portion of the tub that protrudes inward.

4. The dishwasher of claim 2 , wherein the bracket coupler further comprises:
a plate portion configured to protrude inward of the tub; and
a bent portion configured to extend to be stepped from the plate portion.

5. The dishwasher of claim 2 , wherein the mount comprises
a flat surface portion configured to be in contact with and supported by a surface of the bracket;
an inclined surface portion configured to be in contact with and supported by the seam; and
a contact surface portion in front of the flat surface portion and the inclined surface portion so as to be in contact with the seal.

6. The dishwasher of claim 5 , wherein
the contact surface portion further comprises an inclined portion having an inclination corresponding to the bracket coupler.

7. The dishwasher of claim 1 , wherein
the at least two panels of the tub comprise an upper panel, a lower panel, and a middle panel, and
the seam comprises a seaming portion including
a first seaming portion formed between the upper panel and the middle panel; and
a second seaming portion formed between the lower panel and the middle panel.

8. The dishwasher of claim 7 , wherein
the mount is provided in at least one of the first seaming portion and the second seaming portion.

9. The dishwasher of claim 1 , wherein the bracket has an I-shaped cross-section.

10. The dishwasher of claim 9 , wherein the bracket further comprises a protrusion having one end which protrudes inward to inhibit separation of the seal.

11. The dishwasher of claim 1 , wherein the mount comprises:
a mounting body; and
a separation prevention portion extending from the mounting body.

12. The dishwasher of claim 1 , wherein the mount further comprises:
a flange shaped to support the bracket and the seam; and
a wing to inhibit the mount from being separated toward an inside of the tub.

13. The dishwasher of claim 1 , wherein the mount comprises a plastic or rubber or stainless-steel material.

14. The dishwasher of claim 1 , wherein
the bracket and the tub are coupled by at least one of welding, clinching, bonding, riveting, and screwing.

15. A dishwasher comprising:
a main body;
a tub in the main body and configured to form a washing space, the tub having an opening and a seam between at least two panels forming the tub;
a door configured to open and close the opening of the tub;
a bracket extending from an inner surface of the tub to form a gap between the tub and the bracket;
a coupler coupled to the bracket and positioned on the seam in the tub;
a seal positioned in the space between the tub and the bracket and supported by the coupler to seal the gap between the tub and the bracket.
