Abstract

Provided is a laundry treating apparatus including a drum, a circular guide, and a panel. The drum holds laundry, has a front side and a rear side opened, and has a cross-section of a noncircular looped curve in which a distance from a rotation center is not uniform. The circular guide rotatably supports a portion of the drum in which a section curvature is uniform. The panel is provided on a front side or a rear side of the drum and supports the circular guide such that the circular guide is rotatable.

First claim

What is claimed is:

1. A laundry treating apparatus, comprising:
a drum to hold laundry, the drum having an opened front axial end and an opened rear axial end, and the drum having a cross-section including at least one first portion having a uniform curvature and at least one second portion having a non-uniform curvature;
a panel provided at a front or a rear of the drum to seal the front axial end or the rear axial end of the drum;
a circular guide coupled between the panel and the corresponding axial end of the drum to support the drum; and
a panel seal provided between the drum and the panel,
wherein the circular guide has a ring shape and is rotatably provided on the panel,
wherein a portion of an outer surface of the circular guide contacts an inner surface of a front or a rear of the at least one first portion of the drum,
wherein an inner surface of a front or rear of the at least one second portion of the drum does not contact the circular guide,
wherein the panel seal is positioned closer to an axial center of the drum than the circular guide is positioned, and
wherein an outer edge of the panel seal contacts the inner surface of the front or rear of both the first and second portion of the drum.

2. The laundry treating apparatus of claim 1 , wherein the panel seal is coupled to the panel such that the panel seal maintains contact with an inner surface of the drum.

3. The laundry treating apparatus of claim 1 , wherein the panel is positioned along the inner surface of the drum, with the panel seal closing a gap between an outer periphery of the panel and an inner periphery of the drum.

4. The laundry treating apparatus of claim 1 , wherein a cross-sectional shape of the end of the panel facing the front axial end of the rear axial end of the drum is the same as a cross-sectional shape of the front axial end or the rear axial end of the drum.

5. The laundry treating apparatus of claim 1 , wherein the panel further comprises a circular guide supporting part supporting the circular guide.

6. The laundry treating apparatus of claim 1 , wherein the drum comprises a drum body that defines a peripheral wall of the drum, and a drum seal provided along an edge of the drum body so as to contact the circular guide.

7. The laundry treating apparatus of claim 6 , wherein the drum seal surrounds the edge of the drum body and contacts a corresponding side surface of the circular guide.

8. The laundry treating apparatus of claim 6 , wherein at least part of the drum seal contacts the panel seal.

9. The laundry treating apparatus of claim 6 , wherein the drum seal seals a gap between the drum body and the circular guide.

10. The laundry treating apparatus of claim 6 , wherein the drum seal contacts with a lateral surface of the circular guide to prevent separation of the drum body from the circular guide.

11. The laundry treating apparatus of claim 1 , wherein a cross-sectional shape of the panel seal facing the front axial end or the rear axial end of the drum is the same as a cross-sectional shape of the front axial end or the rear axial end of the drum.
