Abstract

A home cooking appliance includes a cooktop surface and a gas pedestal burner on the cooktop surface. The gas pedestal burner includes a burner portion having a sidewall, a lower surface facing the cooktop surface, a plurality of burner ports in the sidewall, and a base portion under the burner portion. The base portion elevates the burner portion in a vertical direction above the cooktop surface and has a lower mounting surface disposed on the cooktop surface. An area of a footprint of the lower mounting surface of the base portion is less than an area of a footprint of the lower surface of the burner portion.

First claim

What is claimed is:

1. A home cooking appliance comprising:
an upward facing cooktop surface;
a venturi tube;
a gas pedestal burner on the cooktop surface,
wherein the gas pedestal burner includes:
a burner portion having a sidewall and a lower surface facing the cooktop surface, wherein the sidewall includes a plurality of burner ports; and
a base portion under the burner portion, the base portion elevating the burner portion in a vertical direction above the cooktop surface, the base portion comprising a sidewall enclosing the venturi tube,
wherein the sidewall of the base portion defines a lower mounting surface disposed on the cooktop surface and supporting the gas pedestal burner on the cooktop surface, and
wherein an area of a footprint of the lower mounting surface of the base portion is less than an area of a footprint of the lower surface of the burner portion.

2. The home cooking appliance of claim 1 , wherein a periphery of the base portion increases in a vertical direction from the lower mounting surface up to the lower surface of the burner portion.

3. The home cooking appliance of claim 1 , wherein a periphery of the base portion increases continuously in a vertical direction from the lower mounting surface up to the lower surface of the burner portion.

4. The home cooking appliance of claim 1 , wherein a periphery of the burner portion increases in a vertical direction from the lower surface up to the plurality of burner ports in order to promote airflow of secondary air in the vertical direction along the sidewall of the burner portion up to the plurality of burner ports.

5. The home cooking appliance of claim 1 , wherein a periphery of the burner portion increases continuously in a vertical direction from the lower surface up to the plurality of burner ports in order to promote airflow of secondary air in the vertical direction along the sidewall of the burner portion up to the plurality of burner ports.

6. The home cooking appliance of claim 1 , wherein a periphery of the base portion is less than the periphery of an upper portion.

7. The home cooking appliance of claim 1 , wherein the lower mounting surface of the base portion is coupled directly to the cooktop surface of the home cooking appliance.

8. The home cooking appliance of claim 1 , wherein the lower mounting surface of the base portion is coupled indirectly to the cooktop surface of the home cooking appliance.

9. The home cooking appliance of claim 1 , further comprising an intervening part on the cooktop surface, wherein the lower mounting surface of the base portion is coupled to the intervening part on the cooktop surface.

10. The home cooking appliance of claim 9 , wherein the lower mounting surface of the base portion is sealed to the intervening part on the cooktop surface.

11. The home cooking appliance of claim 1 , wherein the cooktop surface includes an integral volcano-type pedestal, and
wherein the lower mounting surface of the base portion of the gas pedestal burner is disposed on the integral volcano-type pedestal.

12. The home cooking appliance of claim 11 , wherein the integral volcano-type pedestal has a circular footprint, and
wherein the footprint of the lower mounting surface of the base portion of the gas pedestal burner is a corresponding circular footprint.

13. The home cooking appliance of claim 11 , wherein the integral volcano-type pedestal has an oval footprint, and
wherein the footprint of the lower mounting surface of the base portion of the gas pedestal burner is a corresponding oval footprint.

14. The home cooking appliance of claim 11 , wherein the integral volcano-type pedestal has a tear-drop shaped footprint, and
wherein the footprint of the lower mounting surface of the base portion of the gas pedestal burner is a corresponding tear-drop shaped footprint.

15. The home cooking appliance of claim 11 , wherein the lower mounting surface of the base portion is sealed to the integral volcano-type pedestal.

16. The home cooking appliance of claim 1 , wherein the burner portion has a plurality of finger portions.

17. The home cooking appliance of claim 16 , wherein the base portion includes an ignitor mounting surface having a burner ignitor, and
wherein the ignitor mounting surface extends radially from the base portion and between two adjacent fingers of the plurality of finger portions of the burner portion.

18. The home cooking appliance of claim 16 , further comprising a burner cap on an upper surface of the sidewall of the burner portion.

19. The home cooking appliance of claim 1 , wherein the burner portion has a star-shaped footprint.

20. The home cooking appliance of claim 1 , wherein the burner portion has one of a round footprint and an oval footprint.

21. The home cooking appliance of claim 1 , wherein the lower mounting surface of the base portion is sealed to the cooktop surface.

22. The home cooking appliance of claim 1 , wherein the lower mounting surface of the base portion is integrally formed with another part on the cooktop surface of the home cooking appliance.

23. The home cooking appliance of claim 1 , wherein the gas pedestal burner is a sealed gas burner.

24. The home cooking appliance of claim 1 , wherein the base portion is separately formed from the burner portion.

25. The home cooking appliance of claim 1 , wherein the footprint of the lower mounting surface of the base portion of the gas pedestal burner is a circular footprint.

26. The home cooking appliance of claim 1 , wherein the footprint of the lower mounting surface of the base portion of the gas pedestal burner is an oval footprint.

27. The home cooking appliance of claim 1 , wherein the footprint of the lower mounting surface of the base portion of the gas pedestal burner is a tear-drop shaped footprint.

28. The home cooking appliance of claim 1 , wherein the cooktop surface includes an opening under the base portion of the gas pedestal burner,
wherein the burner portion of the gas pedestal burner includes a cavity in fluid communication with the plurality of burner ports, and
wherein the base portion of the gas pedestal burner includes one of an opening and a passageway fluidly connecting the opening in the cooktop surface to the cavity of the burner portion.

29. The home cooking appliance of claim 1 , wherein the base portion of the gas pedestal burner includes a second opening and a burner ignitor in the second opening.

30. The home cooking appliance of claim 1 , wherein a shape of the footprint of the lower mounting surface of the base portion is different than a shape of the footprint of the lower surface of the burner portion.

31. The home cooking appliance of claim 1 , wherein a clearance between the lower surface of the burner portion and the cooktop surface is one of equal to and greater than 19 mm.

32. The home cooking appliance of claim 1 , wherein a clearance between an upper surface of the sidewall of the burner portion and the cooktop surface is one of equal to and greater than 25 mm.

33. A home cooking appliance comprising:
an upward facing cooktop surface having an opening;
