Abstract

A domestic home gas cooktop is provided. The cooktop has a top sheet having a primary combustion air hole through the top sheet; a gas burner cup mounted to the top sheet; and a gas burner base mounted to the burner cup. The primary combustion air hole is configured to allow first primary combustion air to flow from beneath the top sheet to the burner base, and the primary combustion air hole is located remotely from the burner cup.

First claim

What is claimed is:

1. A domestic home gas cooktop, comprising:
a top sheet having a primary combustion air hole through the top sheet;
a gas burner cup mounted to the top sheet; and
a gas burner base mounted to the burner cup,
wherein the primary combustion air hole is configured to allow first primary combustion air to flow from beneath the top sheet to the burner base, and
the primary combustion air hole is located remotely from the burner cup.

2. The cooktop of claim 1 , further comprising a burner cap mounted to the burner base.

3. The cooktop of claim 1 , wherein the burner base comprises a passageway from below the burner base to above the burner base, and
a first primary combustion air flow path exists from below the top sheet, then through the primary air combustion hole, then through the burner cup, and then through the passageway.

4. The cooktop of claim 3 , wherein the primary combustion air hole comprises a plurality of primary combustion air holes.

5. The cooktop of claim 4 , wherein the plurality of primary combustion air holes are arranged around a perimeter of the burner cup.

6. The cooktop of claim 5 , wherein the plurality of primary combustion air holes are arranged symmetrically around a perimeter of the burner cup.

7. The cooktop of claim 6 , wherein the burner base extends radially from a vertical central axis of the burner base.

8. The cooktop of claim 7 , wherein the plurality of primary combustion air holes are located vertically beneath the burner base in a direction parallel to the vertical central axis of the burner base.

9. The cooktop of claim 8 , wherein a space exists vertically between the burner base and the top sheet, and
a second primary combustion air flow path exists from radially outside of the burner base, then through the space, then through the burner cup, and then through the passageway.

10. The cooktop of claim 9 , wherein the first primary combustion air flow path and the second primary combustion air flow path converge in the space.

11. The cooktop of claim 3 , wherein the burner base extends radially from a vertical central axis of the burner base.

12. The cooktop of claim 11 , wherein the primary combustion air hole is located vertically beneath the burner base in a direction parallel to the vertical central axis of the burner base.

13. The cooktop of claim 12 , wherein a space exists vertically between the burner base and the top sheet, and
a second primary combustion air flow path exists from radially outside of the burner base, then through the space, then through the burner cup, and then through the passageway.

14. The cooktop of claim 13 , wherein the first primary combustion air flow path and the second primary combustion air flow path converge in the space.

15. A domestic home cooking appliance, comprising:
a cooking space, the cooking space being accessible through a door;
a top sheet having a primary combustion air hole through the top sheet, the top sheet being located vertically above the cooking space;
a gas burner cup mounted to the top sheet; and
a gas burner base mounted to the burner cup,
wherein the primary combustion air hole is configured to allow first primary combustion air to flow from beneath the top sheet to the burner base, and
the primary combustion air hole is located remotely from the burner cup.

16. The appliance of claim 15 , wherein the burner base comprises a passageway from below the burner base to above the burner base, and
a first primary combustion air flow path exists from below the top sheet, then through the primary air combustion hole, then through the burner cup, and then through the passageway.

17. The appliance of claim 16 , wherein the burner base extends radially from a vertical central axis of the burner base, and
the primary combustion air hole is located vertically beneath the burner base in a direction parallel to the vertical central axis of the burner base.

18. The appliance of claim 17 , wherein a space exists vertically between the burner base and the top sheet, and
a second primary combustion air flow path exists from radially outside of the burner base, then through the space, then through the burner cup, and then through the passageway.

19. The appliance of claim 18 , wherein the first primary combustion air flow path and the second primary combustion air flow path converge in the space.

20. A method of burning gas with a domestic home gas cooktop, the cooktop having a top sheet having a primary combustion air hole through the top sheet, a gas burner cup mounted to the top sheet, and a gas burner base mounted to the burner cup, the method comprising:
channeling first primary combustion air from beneath the top sheet, through the primary combustion air hole, and to the burner base;
mixing the primary combustion air with a supply of the gas; and
burning, in the burner base, the gas mixed with the primary combustion air,
wherein the primary combustion air hole is located remotely from the burner cup.
