Abstract

A door gasket for a washing machine appliance includes a front ring engaging a front panel of the cabinet and extending around an opening defined by the front panel. A web extends from the front ring toward the wash tub and includes a flexing region (e.g., an S-fold) at least partially defining a trough. A back ring engages the wash tub and defines a plurality of venting apertures that provide fluid communication between the trough and the wash tub.

First claim

What is claimed is:

1. A washing machine appliance comprising:
a cabinet comprising a front panel defining an opening;
a wash tub positioned within the cabinet;
a wash basket rotatably mounted within the wash tub and defining a wash chamber for receiving a load of articles for washing;
a door rotatably mounted to the cabinet for providing selective access to the wash chamber through the opening; and
a gasket extending around the opening and extending from the wash tub for sealing against the door when the door is in a closed position, the gasket comprising:
a front ring engaging the front panel of the cabinet;
a web extending from the front ring toward the wash tub, the web comprising a flexing region at least partially defining a trough; and
a back ring engaging the wash tub, the back ring defining a plurality of venting apertures configured to provide fluid communication between the trough and the wash tub.

2. The washing machine appliance of claim 1 , wherein the wash tub defines tub apertures which correspond to the venting apertures such that the venting apertures and tub apertures extend from the trough through and into the wash tub.

3. The washing machine appliance of claim 1 , wherein the venting apertures are spaced equidistantly about an entire circumference of the back ring.

4. The washing machine appliance of claim 1 , wherein at least one of the venting apertures is positioned above a bottom quarter of a height of the back ring along the vertical direction, wherein the height is measured between a top and a bottom of the gasket along the vertical direction.

5. The washing machine appliance of claim 1 , wherein at least one of the venting apertures is positioned in a top half of a height of the back ring along the vertical direction, wherein the height is measured between a top and a bottom of the gasket along the vertical direction.

6. The washing machine appliance of claim 1 , wherein the back ring defines a contact area where the back ring engages a front flange of the wash tub, and wherein the wash tub apertures are defined in the front flange.

7. The washing machine appliance of claim 6 , wherein the venting apertures define a collective area, and wherein a void ratio of the collective area over the contact area is greater than 0.2.

8. The washing machine appliance of claim 6 , wherein the venting apertures define a collective area, and wherein a void ratio of the collective area over the contact area is greater than 0.5.

9. The washing machine appliance of claim 1 , wherein the flexing region defines a fresh air intake port at a top of the gasket along the vertical direction, the fresh air intake port being in fluid communication with the trough.

10. The washing machine appliance of claim 1 , wherein the venting apertures comprise more than 20 apertures.

11. The washing machine appliance of claim 1 , wherein at least one of the venting apertures is an elongated slot.

12. The washing machine appliance of claim 11 , wherein the drain holes have a different shape than the venting apertures.

13. The washing machine appliance of claim 1 , wherein the back ring of the gasket further defines drain holes positioned at the bottom of the gasket along the vertical direction.

14. A door gasket for a washing machine appliance, the washing machine appliance comprising a cabinet having a front panel defining an opening, a wash tub positioned within the cabinet, and a door rotatably mounted to the cabinet, the door gasket comprising:
a front ring engaging the front panel of the cabinet and extending around the opening;
a web extending from the front ring toward the wash tub, the web comprising a flexing region at least partially defining a trough; and
a back ring engaging the wash tub, the back ring defining a plurality of venting apertures configured to provide fluid communication between the trough and the wash tub.

15. The door gasket of claim 14 , wherein the wash tub defines tub apertures which correspond to the venting apertures such that the venting apertures and tub apertures extend from the trough through and into the wash tub.

16. The door gasket of claim 14 , wherein the venting apertures are spaced equidistantly about an entire circumference of the back ring.

17. The door gasket of claim 14 , wherein at least one of the venting apertures is positioned above a bottom quarter of a height of the back ring along the vertical direction, wherein the height is measured between a top and a bottom of the gasket along the vertical direction.

18. The door gasket of claim 14 , wherein at least one of the venting apertures is positioned in a top half of a height of the back ring along the vertical direction, wherein the height is measured between a top and a bottom of the gasket along the vertical direction.

19. The door gasket of claim 14 , wherein the back ring defines a contact area where the back ring engages a front flange of the wash tub, and wherein the wash tub apertures are defined in the front flange, and wherein the venting apertures define a collective area, and wherein a void ratio of the collective area over the contact area is greater than 0.2.

20. The door gasket of claim 14 , wherein the back ring of the door gasket further defines drain holes positioned at the bottom of the door gasket along the vertical direction.
