Abstract

A cooktop appliance includes a top panel that defines an opening. A first gas burner is positioned on the top panel at the opening of the top panel. A second gas burner includes a burner body, a horizontal mixing tube and a fuel orifice. The burner body is positioned on the top panel away from the opening of the top panel. The horizontal mixing tube is positioned below the top panel and extends between the burner body and the fuel orifice. The fuel orifice is positioned below the top panel at the opening of the top panel.

First claim

What is claimed is:

1. A cooktop appliance, comprising:
a top panel that defines an opening;
a first gas burner positioned on the top panel at the opening of the top panel, a fuel orifice of the first gas burner positioned below the top panel at the opening of the top panel; and
a second gas burner comprising a burner body, a horizontal mixing tube and a fuel orifice, the burner body positioned on the top panel away from the opening of the top panel, the horizontal mixing tube positioned below the top panel and extending between the burner body and the fuel orifice of the second gas burner, the fuel orifice of the second gas burner positioned below the top panel at the opening of the top panel,
wherein the fuel orifice of the first gas burner and the fuel orifice of the second gas burner are positioned directly below the opening of the top panel.

2. The cooktop appliance of claim 1 , wherein the fuel orifice of the second gas burner is positioned below the opening of the top panel such that the fuel orifice of the second gas burner is accessible through the opening of the top panel.

3. The cooktop appliance of claim 2 , wherein the fuel orifice of the second gas burner is accessible through the opening of the top panel such that the fuel orifice of the second gas burner is changeable between a natural gas fuel orifice and a propane fuel orifice through the opening of the top panel.

4. The cooktop appliance of claim 1 , further comprising an injet bracket mounted to the top panel below the first gas burner, a fuel orifice of the first gas burner mounted on the injet bracket, the fuel orifice of the second gas burner also mounted on the injet bracket.

5. The cooktop appliance of claim 4 , wherein the fuel orifice of the first gas burner and the fuel orifice of the second gas burner are threaded to the inlet bracket.

6. The cooktop appliance of claim 1 , wherein the burner body is positioned on the top panel such that the burner body is spaced from the opening of the top panel by no less than five inches and no more than twenty inches.

7. The cooktop appliance of claim 1 , wherein an inlet of the horizontal mixing tube is positioned adjacent the fuel orifice of the second gas burner.

8. The cooktop appliance of claim 1 , wherein the horizontal mixing tube is a horizontal Venturi mixing tube.

9. The cooktop appliance of claim 1 , wherein the first gas burner comprises a burner body and a vertical mixing tube, the burner body of the first gas burner positioned on the top panel, the fuel orifice of the first gas burner positioned below the top panel, the vertical mixing tube extending through the opening of the top panel between the burner body of the first gas burner and the fuel orifice of the first gas burner.

10. The cooktop appliance of claim 9 , wherein the second gas burner is configured such that the second gas burner has a greater maximum heat output than the first gas burner.

11. A cooktop appliance, comprising:
a top panel that defines an opening;
a first gas burner comprising a burner body, a vertical mixing tube and a fuel orifice, the burner body of the first gas burner positioned on the top panel at the opening of the top panel, the fuel orifice of the first gas burner positioned below the top panel, the vertical mixing tube extending through the opening of the top panel between the burner body of the first gas burner and the fuel orifice of the first gas burner;
a second gas burner comprising a burner body, a horizontal mixing tube and a fuel orifice, the burner body of the second gas burner positioned on the top panel away from the opening of the top panel, the horizontal mixing tube positioned below the top panel and extending between the burner body of the second gas burner and the fuel orifice of the second gas burner, the fuel orifice of the second gas burner positioned below the opening of the top panel such that the fuel orifice of the second gas burner is accessible through the opening of the top panel,
wherein the fuel orifice of the first gas burner and the fuel orifice of the second gas burner are positioned directly below the opening of the top panel.

12. The cooktop appliance of claim 11 , wherein the fuel orifice of the second gas burner is accessible through the opening of the top panel such that the fuel orifice of the second gas burner is changeable between a natural gas fuel orifice and a propane fuel orifice through the opening of the top panel.

13. The cooktop appliance of claim 11 , further comprising an injet bracket mounted to the top panel below the first gas burner, the fuel orifices of the first and second gas burners both mounted on the injet bracket.

14. The cooktop appliance of claim 13 , wherein the fuel orifice of the first gas burner and the fuel orifice of the second gas burner are threaded to the injet bracket.

15. The cooktop appliance of claim 11 , wherein the burner body of the second gas burner is positioned on the top panel such that the burner body of the second gas burner is spaced from the opening of the top panel by no less than five inches and no more than twenty inches.

16. The cooktop appliance of claim 11 , wherein an inlet of the horizontal mixing tube is positioned adjacent the fuel orifice of the second gas burner.

17. The cooktop appliance of claim 11 , wherein the horizontal mixing tube is a horizontal Venturi mixing tube.

18. The cooktop appliance of claim 11 , wherein the second gas burner is configured such that the second gas burner has a greater maximum heat output than the first gas burner.
