Abstract

A gas burner assembly for an appliance includes a circular inner wall that defines a plurality of inner flame ports. An elongated outer wall extends around the circular inner wall such that the elongated outer wall is spaced from the circular inner wall. The elongated outer wall defines a plurality of outer flame ports. A cap is positioned on the circular inner wall over the plurality of inner flame ports and on the elongated outer wall over the plurality of outer flame ports.

First claim

What is claimed is:

1. A gas burner assembly for an appliance, comprising:
a circular inner wall defining a plurality of inner flame ports;
an elongated outer wall extending around the circular inner wall such that the elongated outer wall is spaced from the circular inner wall, the elongated outer wall defining a plurality of outer flame ports; a bottom wall, wherein the circular inner wall and the elongated outer wall are mounted to the bottom wall such that the circular inner wall and the elongated outer wall extend upwardly from the bottom wall; and
a cap positioned on the circular inner wall over the plurality of inner flame ports and on the elongated outer wall over the plurality of outer flame port;
wherein the circular inner wall, the elongated outer wall and the bottom wall are integrally formed from a single piece of metal.

2. The gas burner assembly of claim 1 , further comprising at least one support extending downwardly from the bottom wall, the at least one support positionable on an appliance top panel so that the bottom wall is spaced from the appliance top panel and air is flowable between the appliance top panel and the bottom wall to the plurality of inner flame ports.

3. The gas burner assembly of claim 1 , wherein the inner flame ports are oriented offset from a center of the circular inner wall such that fuel exiting the inner flame ports swirls about the center of the circular inner wall.

4. The gas burner assembly of claim 1 , wherein the elongated outer wall has a first portion and a second portion, the first portion of the elongated outer wall positioned no less two inches further from a center of the circular inner wall than the second portion of the elongated outer wall.

5. The gas burner assembly of claim 1 , further comprising an intermediate wall positioned between the circular inner wall and the elongated outer wall, the intermediate wall positioned between an inner fuel chamber from an outer fuel chamber such that the inner fuel chamber is separate from the outer fuel chamber, the outer flame ports contiguous with the outer fuel chamber, the inner flame ports contiguous with the inner fuel chamber.

6. The gas burner assembly of claim 5 , further comprising a bottom wall and at least one support, wherein the circular inner wall, the elongated outer wall and the intermediate wall are integrally formed with the bottom wall such that the circular inner wall, the elongated outer wall and the intermediate wall extend upwardly from the bottom wall, the at least one support extending downwardly from the bottom wall, the at least one support positionable on an appliance top panel so that the bottom wall is spaced from the appliance top panel and air is flowable between the appliance top panel and the bottom wall to the plurality of inner flame ports.

7. The gas burner assembly of claim 1 , wherein the cap defines a flat top surface that extends over the circular inner wall and the elongated outer wall, the cap also defining a circular opening that is positioned proximate the inner flame ports.

8. The gas burner assembly of claim 1 , wherein the circular inner wall is circular and the elongated outer wall is non-circular in a plane that is perpendicular to a vertical direction.

9. An appliance, comprising:
a top panel;
a gas burner assembly positioned at the top panel, the gas burner assembly comprising
a circular inner wall defining a plurality of inner flame ports;
an elongated outer wall extending around the circular inner wall such that the elongated outer wall is spaced from the circular inner wall, the elongated outer wall defining a plurality of outer flame ports;
a bottom wall, the circular inner wall and the elongated outer wall mounted to the bottom wall such that the circular inner wall and the elongated outer wall extend upwardly from the bottom wall; and
a cap positioned on the circular inner wall over the plurality of inner flame ports and on the elongated outer wall over the plurality of outer flame ports;
wherein the circular inner wall, the elongated outer wall and the bottom wall are integrally formed from a single piece of metal.

10. The appliance of claim 9 , wherein the gas burner assembly further comprises at least one support extending downwardly from the bottom wall, the at least one support positioned the top panel so that the bottom wall is spaced from the top panel and air is flowable between the top panel and the bottom wall to the plurality of inner flame ports.

11. The appliance of claim 9 , wherein the inner flame ports are oriented offset from a center of the circular inner wall such that fuel exiting the inner flame ports swirls about the center of the circular inner wall.

12. The appliance of claim 9 , wherein the elongated outer wall has a first portion and a second portion, the first portion of the elongated outer wall positioned no less two inches further from a center of the circular inner wall than the second portion of the elongated outer wall.

13. The appliance of claim 9 , wherein the gas burner assembly further comprises an intermediate wall positioned between the circular inner wall and the elongated outer wall, the intermediate wall positioned between an inner fuel chamber from an outer fuel chamber such that the inner fuel chamber is separate from the outer fuel chamber, the outer flame ports contiguous with the outer fuel chamber, the inner flame ports contiguous with the inner fuel chamber.

14. The appliance of claim 13 , wherein the gas burner assembly further comprises a bottom wall and at least one support, the circular inner wall, the elongated outer wall and the intermediate wall integrally formed with the bottom wall such that the circular inner wall, the elongated outer wall and the intermediate wall extend upwardly from the bottom wall, the at least one support extending downwardly from the bottom wall, the at least one support positioned on the top panel so that the bottom wall is spaced from the top panel and air is flowable between the top panel and the bottom wall to the plurality of inner flame ports.

15. The appliance of claim 9 , wherein the cap defines a flat top surface that extends over the circular inner wall and the elongated outer wall, the cap also defining a circular opening that is positioned proximate the inner flame ports.

16. The appliance of claim 9 , wherein the circular inner wall is circular and the elongated outer wall is non-circular in a plane that is perpendicular to a vertical direction.
