Abstract

A gas burner assembly includes a grate that defines a first internal fuel passage and a second internal fuel passage. A burner defines an inner burner ring and an outer burner ring. The first internal fuel passage of the grate extends to the inner burner ring, and the second internal fuel passage of the grate extends to the outer burner ring. A fuel chamber of the inner burner ring is contiguous with the plurality of flame ports of inner burner ring, and a fuel chamber of the outer burner ring is contiguous with the plurality of flame ports of outer burner ring. At least a portion of the fuel chamber of the outer burner ring is positioned directly below the fuel chamber of the inner burner ring.

First claim

What is claimed is:

1. A gas burner assembly, comprising:
a grate configured for supporting a cooking utensil, the grate defining a first internal fuel passage and a second internal fuel passage; and
a burner defining an inner burner ring and an outer burner ring, the inner burner ring and the outer burner ring each defining a plurality of flame ports, the first internal fuel passage of the grate extending to the inner burner ring such that fuel is directed to the inner burner ring via the first internal fuel passage of the grate, the second internal fuel passage of the grate extending to the outer burner ring such that fuel is directed to the outer burner ring via the second internal fuel passage of the grate,
wherein the inner burner ring and the outer burner ring each define a fuel chamber, the fuel chamber of the inner burner ring contiguous with the plurality of flame ports of inner burner ring, the fuel chamber of the outer burner ring contiguous with the plurality of flame ports of outer burner ring, at least a portion of the fuel chamber of the outer burner ring positioned directly below the fuel chamber of the inner burner ring, and
wherein at least a portion of the first internal fuel passage is positioned above the plurality of flame ports of inner burner ring and at least a portion of the second internal fuel passage is positioned above the plurality of flame ports of outer burner ring.

2. The gas burner assembly of claim 1 , wherein the second internal fuel passage of the grate extends between an inlet and an outlet, the outlet of the second internal fuel passage configured for directing fuel from the second internal fuel passage of the grate into the fuel chamber of the outer burner ring, the fuel chamber of the outer burner ring positioned directly below the fuel chamber of the inner burner ring proximate the outlet of the second internal fuel passage such that fuel from the second internal fuel passage of the grate flowing into the fuel chamber of the outer burner ring from the outlet of the second internal fuel passage flows beneath the fuel chamber of the inner burner ring within the fuel chamber of the outer burner ring.

3. The gas burner assembly of claim 1 , wherein the burner comprises a crossover duct that extends between the inner burner ring and the outer burner ring, the crossover duct configured for transferring flames between the inner burner ring and the outer burner ring.

4. The gas burner assembly of claim 3 , wherein a bottom wall of the crossover duct is spaced apart from a bottom wall of the outer burner ring such that fuel within the fuel chamber of the outer burner ring flows between the bottom wall of the crossover duct and the bottom wall of the outer burner ring.

5. The gas burner assembly of claim 3 , wherein the fuel chamber of the outer burner ring extends beneath the crossover duct.

6. The gas burner assembly of claim 3 , wherein the burner comprises a cap, an outer base and an inner base, the cap of the burner integrally formed with the grate, the outer base of the burner mounted to the cap such that the cap and the outer base of the burner define the plurality of flame ports of outer burner ring, the inner base of the burner nested within the outer base such that the cap and the inner base of the burner define the plurality of flame ports of inner burner ring.

7. The gas burner assembly of claim 6 , wherein a bottom wall of the crossover duct is integrally formed with the inner base.

8. The gas burner assembly of claim 6 , wherein a bottom wall of the inner base is spaced apart from a bottom wall of the outer burner ring such that fuel within the fuel chamber of the outer burner ring flows between the bottom wall of the inner base and the bottom wall of the outer burner ring.

9. The gas burner assembly of claim 1 , wherein an outlet of the first internal fuel passage is positioned opposite an outlet of the second internal fuel passage on the burner.

10. A gas burner assembly, comprising:
a grate configured for supporting a cooking utensil, the grate defining a first internal fuel passage and a second internal fuel passage; and
a burner defining an inner burner ring and an outer burner ring, the inner burner ring and the outer burner ring each defining a plurality of flame ports, the first internal fuel passage of the grate extending to the inner burner ring such that fuel is directed to the inner burner ring via the first internal fuel passage of the grate, the second internal fuel passage of the grate extending to the outer burner ring such that fuel is directed to the outer burner ring via the second internal fuel passage of the grate,
wherein the inner burner ring and the outer burner ring each define a fuel chamber, the fuel chamber of the inner burner ring contiguous with the plurality of flame ports of inner burner ring, the fuel chamber of the outer burner ring contiguous with the plurality of flame ports of outer burner ring, a bottom wall of the inner burner ring and a bottom wall of the outer burner ring spaced apart from each other at the fuel chamber of the outer burner ring such that the fuel chamber of the outer burner ring is disposed between the bottom wall of the inner burner ring and the bottom wall of the outer burner ring, and
wherein the second internal fuel passage of the grate extends between an inlet and an outlet, the outlet of the second internal fuel passage configured for directing fuel from the second internal fuel passage of the grate into the fuel chamber of the outer burner ring, the fuel chamber of the outer burner ring is disposed between the bottom wall of the inner burner ring and the bottom wall of the outer burner ring proximate the outlet of the second internal fuel passage such that fuel from the second internal fuel passage of the grate flowing into the fuel chamber of the outer burner ring from the outlet of the second internal fuel passage flows between the bottom wall of the inner burner ring and the bottom wall of the outer burner ring within the fuel chamber of the outer burner ring.

11. The gas burner assembly of claim 10 , wherein at least a portion of the first internal fuel passage is positioned above the plurality of flame ports of inner burner ring and at least a portion of the second internal fuel passage is positioned above the plurality of flame ports of outer burner ring.

12. The gas burner assembly of claim 10 , wherein the burner comprises a crossover duct that extends between the inner burner ring and the outer burner ring, the crossover duct configured for transferring flames between the inner burner ring and the outer burner ring.

13. The gas burner assembly of claim 12 , wherein a bottom wall of the crossover duct is spaced apart from the bottom wall of the outer burner ring such that fuel within the fuel chamber of the outer burner ring flows between the bottom wall of the crossover duct and the bottom wall of the outer burner ring.

14. The gas burner assembly of claim 12 , wherein the fuel chamber of the outer burner ring extends beneath the crossover duct.

15. The gas burner assembly of claim 12 , wherein the burner comprises a cap, an outer base and an inner base, the cap of the burner integrally formed with the grate, the outer base of the burner mounted to the cap such that the cap and the outer base of the burner define the plurality of flame ports of outer burner ring, the inner base of the burner nested within the outer base such that the cap and the inner base of the burner define the plurality of flame ports of inner burner ring.
