Abstract

An over door spill diverter system for the routing of liquid entering an oven door at or near its top. Liquid is diverted away from the window to prevent stains on the inside surface that a user may not be able to readily clean or otherwise remove. The diverter system also allows for convective air flow through the oven door to properly cool the exterior of the door. A variety of oven door constructions may be utilized.

First claim

What is claimed is:

1. A door for an oven appliance, the door defining vertical, lateral, and transverse directions, the door comprising:
an exterior wall;
an interior wall, the exterior wall and interior wall extending along the vertical direction between a top portion and a bottom portion of the door and extending along the lateral direction between opposing lateral sides of the door;
a cavity defined at least in part by the exterior wall and the interior wall and located therebetween;
ventilation ports positioned near the top of portion of the door;
a first diverter positioned within the cavity below the ventilation ports and adjacent to the exterior wall, the first diverter including a first trough extending longitudinally at a non-zero angle from the lateral direction so as to cause liquid to flow towards at least one of the opposing lateral sides of the door;
a deflector positioned within the cavity adjacent to the ventilation ports and above the first trough, the deflector spaced apart along the transverse direction from the exterior wall, the deflector having a lip angled towards the exterior wall so as to cause liquid to flow towards the exterior wall; and
a second diverter positioned within the cavity below the ventilation ports and adjacent to the interior wall, the second diverter including a second trough extending longitudinally at a non-zero angle from the lateral direction so as to cause liquid to flow towards at least one of the opposing lateral sides of the door.

2. The door for an oven appliance as in claim 1 , wherein the first diverter is attached to the exterior wall.

3. The door for an oven appliance as in claim 2 , wherein the first diverter comprises a metal sheet having a bend along one edge so as to form the first trough.

4. The door for an oven appliance as in claim 2 , wherein the second diverter is attached to the interior wall.

5. The door for an oven appliance as in claim 4 , wherein the second diverter comprises a metal sheet having a bend along one edge so as to form the second trough.

6. The door for an oven appliance as in claim 5 , wherein the diverter is attached to one of the opposing sides of the door.

7. The door for an oven appliance as in claim 1 , wherein the ventilation ports are positioned on the exterior wall.

8. The door for an oven appliance as in claim 7 , wherein the first diverter comprises a top edge positioned vertically below the ventilation ports.

9. The door for an oven appliance as in claim 1 , wherein the lip of the deflector comprises a lip edge that is positioned directly over the first trough of the first diverter.

10. The door for an oven appliance as in claim 1 , wherein the deflector comprises a top edge having a pair of attachment posts extending along the vertical direction.

11. The door for an oven appliance as in claim 1 , further comprising a window having a see-through portion, and wherein the first trough, second trough, and lip are positioned above the see-through portion along the vertical direction.

12. An oven appliance, comprising:
a cook top surface including one or more heating elements positioned at the cook top surface;
a user interface panel positioned at the cook top surface;
an oven cavity for receipt of food items for cooking, the oven cavity positioned below the cook top surface
a door defining vertical, lateral, and transverse directions, the door comprising
an exterior wall and an interior wall spaced apart from each other along the transverse direction, the exterior wall defining ventilation ports positioned near a top portion of the door;
a first diverter positioned below the ventilation ports and adjacent to the exterior wall, the first diverter including a first trough extending longitudinally at a non-zero angle from the lateral direction so as to cause liquid to flow towards at least one of the opposing lateral sides of the door;
a deflector positioned adjacent to the ventilation ports and above the first trough, the deflector spaced apart along the transverse direction from the exterior wall, the deflector having a lip angled towards the exterior wall so as to cause liquid to flow towards the exterior wall; and
a second diverter within the cavity below the ventilation ports and adjacent to the interior wall, the second diverter including a second trough extending at a non-zero angle from the lateral direction so as to cause liquid to flow towards at least one of the opposing lateral sides of the door.

13. The oven appliance as in claim 12 , wherein the ventilation ports are positioned on the exterior wall.

14. The oven appliance as in claim 12 , wherein the first diverter comprises a top edge positioned vertically below the ventilation ports, and wherein the first trough is positioned vertically higher than a see-through portion of the door.

15. The oven appliance as in claim 14 , wherein the lip of the deflector comprises a lip edge that is positioned directly over the first trough of the first diverter.

16. The oven appliance as in claim 12 , wherein the deflector comprises a top edge having a pair of attachment posts extending along the vertical direction.

17. The oven appliance as in claim 12 , further comprising a window having a see-through portion, and wherein the first trough, second trough, and lip are positioned above the see-through portion along the vertical direction.

18. The oven appliance as in claim 17 , wherein the first trough, the second trough, and the diverter are spaced apart from each other along the lateral direction.
