Abstract

A grilling system for an oven includes a removable grilling platform defined by a food supporting rack, a basin, and a heating element positioned between the rack and the basin. The basin includes a bottom surface which is sloped in order to direct liquid byproducts of the grilling operation either into a collection container or to an auxiliary heating element used to vaporize the liquid byproducts. An exhaust system is provided to purge the oven cavity of gaseous and airborne byproducts.

Claims

1. In a cooking appliance including an oven cavity having an open frontal portion, a door for selectively sealing the open frontal portion, at least one heating element disposed adjacent a bottom portion of said oven cavity and controls for regulating an activation state of said heating element, a combination grilling and byproduct removal system comprising:

a grilling platform mounted within said oven cavity, said grilling platform including a rack for supporting food items to be grilled, a basin arranged below the rack and adapted to catch liquid byproducts generated during grilling, and an additional heating element extending between at least a lower portion of the basin and the rack, said additional heating element being adapted to be operated to grill food items on the rack; and

an exhaust system having an inlet opening into the oven cavity and an outlet leading from the oven cavity, said exhaust system including a fan for drawing grilling byproducts out of the oven cavity.

2. The combination grilling and byproduct removal system according to claim 1, wherein the rack is directly supported by the basin.

3. The combination grilling and byproduct removal system according to claim 2, wherein the basin is formed with at least one upper peripheral ledge portion, said rack being positioned upon said ledge portion.

4. The combination grilling and byproduct removal system according to claim 1, wherein said basin includes a bottom surface which slopes relative to a horizontal.

5. The combination grilling and byproduct removal system according to claim 4, wherein the bottom surface of the basin slopes downwardly from a rear portion of the basin towards a front portion of the basin.

6. The combination grilling and byproduct removal system according to claim 5, further comprising:

a liquid byproduct collection container attached to the bottom surface of the basin.

7. The combination grilling and byproduct removal system according to claim 6, wherein the container is removably attached to the front portion of the basin.

8. The combination grilling and byproduct removal system according to claim 4, wherein the basin includes a funnel portion and the bottom surface of the basin slopes towards the funnel portion.

9. The combination grilling and byproduct removal system according to claim 8, further comprising:

an auxiliary heating element, located adjacent the bottom portion of said oven cavity, for vaporizing at least a portion of the liquid byproducts, thereby producing at least some of the grilling byproducts.

10. The combination grilling and byproduct removal system according to claim 9, wherein the auxiliary heating element is located concentrically within the at least one heating element.

11. In a cooking appliance including an oven cavity having an open frontal portion, a door for selectively sealing the open frontal portion, at least one heating element disposed adjacent a bottom portion of said oven cavity and controls for regulating an activation state of said heating element, a combination grilling and byproduct removal system comprising:

a grilling platform mounted within said oven cavity, said grilling platform including a rack for supporting food items to be grilled and an additional heating element arranged below the rack, said additional heating element being selectively actuatable for grilling food items on the rack;

means, located adjacent the bottom portion of said oven cavity, for vaporizing at least a portion of liquid byproducts, developed in the oven cavity during a grilling operation, into grilling byproducts; and

an exhaust system having an inlet opening into the oven cavity and an outlet leading from the oven cavity, said exhaust system including a fan for drawing the grilling byproducts out of the oven cavity.

12. The combination grilling and byproduct removal system according to claim 11, wherein said vaporizing means comprises an auxiliary heating element.

13. The combination grilling and byproduct removal system according to claim 12, wherein the auxiliary heating element is located concentrically within the at least one heating element.

14. The combination grilling and byproduct removal system according to claim 11, wherein the grilling platform further includes a basin arranged below the rack, said basin being adapted to catch the liquid byproducts generated during grilling.

15. The combination grilling and byproduct removal system according to claim 14, wherein the rack is directly supported by the basin.

16. The combination grilling and byproduct removal system according to claim 15, wherein the basin is formed with at least one upper ledge portion, said rack being positioned upon said ledge portion.

17. The combination grilling and byproduct removal system according to claim 14, wherein said basin includes a bottom surface which slopes relative to a horizontal.

18. The combination grilling and byproduct removal system according to claim 17, wherein the bottom surface of the basin slopes downwardly from a rear portion of the basin towards a front portion of the basin.

19. The combination grilling and byproduct removal system according to claim 18, further comprising:

a liquid byproduct collection container attached to the bottom surface of the basin.

20. The combination grilling and byproduct removal system according to claim 19, wherein the container is removably attached to the front portion of the basin.

21. The combination grilling and byproduct removal system according to claim 17, wherein the basin includes a funnel portion and the bottom surface of the basin slopes towards the funnel portion.

22. A method of grilling food in an oven cavity provided with at least one selectively actualable heating element comprising:

supporting a food item upon a rack, provided as part of a grilling platform, within the oven cavity;

operating an additional heating element, also provided as part of the grilling platform and arranged beneath the rack, to effectuate grilling of the food item, while developing liquid and gaseous byproducts;

vaporizing at least a portion of the liquid byproducts into gaseous byproducts; and

operating an oven cavity exhaust system to remove the gaseous byproducts.

23. The method according to claim 22, further comprising:

operating an auxiliary heating element in a lower portion of the oven cavity to vaporize the portion of the liquid byproducts.

24. The method according to claim 23, further comprising:

directing the liquid byproducts to the auxiliary heating element.

25. The method according to claim 22, further comprising:

collecting a portion of the liquid byproducts in a container of the grilling platform suspended below the rack.

26. The method according to claim 25, further comprising:

positioning a basin below the rack; and

directing the portion of the liquid byproducts to the container along a sloping bottom surface of the basin.

27. The method according to claim 26, further comprising:

detachably securing the container to the basin.

28. The method according to claim 26, further comprising:

supporting the rack upon an upper portion of the basin; and

operating the additional heating element from between the rack and the bottom surface of the basin.
