Abstract

A seal assembly and method for sealing a door and a tub in a laundry treating appliance.

First claim

What is claimed is:

1. A laundry treating appliance configured to execute a cycle of operation for treating laundry, comprising:
a tub at least partially defining an interior and having a rim at one end defining a tub opening providing access to the tub interior;
a drum at least partially defining a treating chamber and having a drum opening providing access to the treating chamber;
a door selectively moveable to close the tub opening comprising:
a flat panel having a generally flat rear planar side facing the tub, wherein the flat panel spans the tub opening and lies exteriorly of the tub opening when the door closes the tub opening;
a frame encasing a periphery of the flat panel; and
a raised element formed on the rear planar side of the flat panel or the frame; and

a seal assembly provided on the tub to seal the rear planar side of the flat panel to the tub and wherein at least a portion of the seal assembly abuts the raised element when the door closes the tub opening.

2. The laundry treating appliance of claim 1 wherein the seal assembly comprises a rigid seal element formed on one of the door or the tub, a flexible seal element projecting from the other of the door and the tub, with the rigid seal element and the flexible seal element abutting each other when the door closes the tub opening.

3. The laundry treating appliance of claim 2 wherein the flexible seal element projects from the tub.

4. The laundry treating appliance of claim 3 wherein at least a portion of the rigid seal element comprises a portion of the frame.

5. The laundry treating appliance of claim 4 wherein the rigid seal element is formed in part by the rear planar side and in part by the raised element and wherein the flexible seal element comprises a first flexible seal that abuts the rear planar side when the door closes the tub and a second flexible seal that abuts the raised element when the door closes the tub opening.

6. The laundry treating appliance of claim 5 wherein the flexible seal element projects from a portion of the tub defining the tub opening.

7. The laundry treating appliance of claim 6 wherein a portion of the drum overlies at least a portion of the flexible seal element.

8. The laundry treating appliance of claim 7 wherein the portion of the drum is the drum opening.

9. The laundry treating appliance of claim 6 wherein the flexible seal element is mounted to the rim of the tub.

10. The laundry treating appliance of claim 2 wherein the rigid seal element circumscribes at least a portion of the rear planar side and the flexible seal element circumscribes the tub opening, the flexible seal element forming a first seal with the rear planar side.

11. The laundry treating appliance of claim 10 wherein the rigid seal element further comprises the raised element and the flexible seal element forms a second seal with the raised element.

12. The laundry treating appliance of claim 1 wherein the drum comprises a drum rim defining the drum opening, and a gap between the drum rim and the tub is insufficient for laundry to pass between.

13. The laundry treating appliance of claim 12 wherein the drum rim is located axially behind the tub rim.

14. The laundry treating appliance of claim 1 wherein the flat panel comprises an at least partially transparent portion.

15. A laundry treating appliance configured to execute a cycle of operation for treating laundry, comprising:
a tub at least partially defining an interior and having a rim at one end defining a tub opening providing access to the tub interior;
a drum at least partially defining a treating chamber and having a drum opening providing access to the treating chamber;
a door selectively moveable to close the tub opening comprising:
a flat panel having a generally flat rear planar side facing the tub, wherein the flat panel spans the tub opening and lies exteriorly of the tub opening when the door closes the tub opening;
a frame mounted to the flat panel and surrounding a periphery thereof; and
a raised element formed on the rear planar side of the flat panel or the frame; and

a seal assembly provided on the tub and configured to seal the rear planar side of the flat panel to the tub, wherein the seal assembly comprises a flexible seal that abuts the raised element when the door closes the tub opening.

16. A laundry treating appliance configured to execute a cycle of operation for treating laundry, comprising:
a tub at least partially defining an interior and having a rim at one end defining a tub opening providing access to the tub interior;
a drum at least partially defining a treating chamber and having a drum opening providing access to the treating chamber;
a door selectively moveable to close the tub opening comprising:
a flat panel having a generally flat rear planar side facing the tub, wherein the flat panel spans the tub opening and lies exteriorly of the tub opening when the door closes the tub opening; and
a frame mounted to the flat panel and having a raised element formed thereon; and

a seal assembly provided on the tub and comprising a first seal that abuts the rear planar side of the flat panel when the door closes the tub opening to form a first axial seal and a second seal that abuts the raised element when the door closes the tub opening to form a second axial seal.
