Abstract

A fuel-burning cooking burner includes a base defining an outer periphery and an inner open area. The burner further includes a cap coupled with the base around the outer periphery thereof and extending over the open area to define a distribution cavity on an interior side of the cap. The cap further defines a convex outer surface extending opposite the distribution cavity and a plurality of outlets extending through the cap from the distribution cavity to the exterior surface. The outlets are distributed over the entire exterior surface.

First claim

What is claimed is:

1. A fuel-burning cooking burner, comprising:
a base defining an outer periphery and an inner open area; and
a cap coupled with the base around the outer periphery thereof and extending over the open area to define a distribution cavity on an interior side of the cap, the cap further defining a convex exterior surface extending opposite the distribution cavity and a plurality of outlets extending through the cap from the distribution cavity to the exterior surface, the outlets being distributed over the entire exterior surface by being arranged in a plurality of concentric rings including an innermost ring, an outermost ring and a plurality of intermediate rings, wherein adjacent ones of the outlets in the outermost ring and the plurality of intermediate rings are spaced apart in a tangential direction around the outer periphery by the same distance.

2. The burner of claim 1 , wherein the outlets are distributed over the entire exterior surface by including at least some of the outlets in the outermost ring positioned adjacent the outer periphery and at least some of the outlets in the innermost ring adjacent a center of the exterior surface.

3. The burner of claim 1 , wherein the outermost ring, the innermost ring, and the plurality of intermediate rings are concentric and emanate from a center of the exterior surface.

4. The burner of claim 3 , wherein the plurality of concentric rings are arranged in a first group and a second group, the first group including the outermost ring and being more closely spaced in a radial direction than the second group, which includes the innermost ring.

5. The burner of claim 3 , wherein the outlets are all of a uniform size of between 1 mm and 2.5 mm.

6. The burner of claim 1 , wherein the base defines a fuel-air mix inlet and a mixing chamber, the mixing chamber being in communication with the fuel-air mix inlet and with the distribution cavity remote from the fuel-air mix inlet and further being separated from a portion of the distribution cavity.

7. The burner of claim 6 , wherein the base includes an inner wall spaced inward from the outer periphery and defining a portion of the mixing chamber surrounding the distribution cavity.

8. The burner of claim 7 , wherein the mixing chamber is open to the distribution cavity along an upper edge of inner wall that is spaced apart from an interior of the cap.

9. The burner of claim 7 , wherein the mixing chamber is open to the distribution cavity through a plurality of ports extending through the wall.

10. A fuel-burning cooking burner, comprising:
a base defining an outer periphery, an inner open area, a mixing chamber separated from a portion of the inner open area and in communication therewith adjacent the outer periphery, and an inner wall spaced inward from the outer periphery and including a plurality of ports extending through the inner wall; and
a cap coupled with the base around the outer periphery thereof and extending over the open area to define a distribution cavity on an interior side of the cap, the cap further defining an exterior surface extending opposite the distribution cavity and a plurality of outlets extending through the cap from the distribution cavity to the exterior surface;
wherein the inner wall defines a portion of the mixing chamber surrounding the distribution cavity and the mixing chamber is open to the distribution cavity through the plurality of ports.

11. The burner of claim 10 , wherein the outlets are distributed over the entire exterior surface.

12. The burner of claim 11 , wherein the outlets are distributed over the entire exterior surface by including at least some of the outlets in positions adjacent the outer periphery and at least some of the outlets adjacent a center of the exterior surface.

13. The burner of claim 12 , wherein the outlets are arranged in concentric rings emanating from a center of the exterior surface.

14. The burner of claim 13 , wherein the concentric rings are more closely spaced in a radial direction toward the outer periphery than toward the center.

15. The burner of claim 13 , wherein the concentric rings are characterized by uniform size and generally equal tangential spacing of the outlets among the concentric rings.

16. The burner of claim 10 , wherein the cap further defines a convex exterior surface extending opposite the distribution cavity.

17. The burner of claim 10 , wherein the mixing chamber is open to the distribution cavity along an upper edge of inner wall that is spaced apart from an interior of the cap.

18. A cooking appliance, comprising:
an upper surface;
a burner disposed along the upper surface, including:
a base defining an outer periphery and an inner open area; and
a cap coupled with the base around the outer periphery thereof and extending over the open area to define a distribution cavity on an interior side of the cap, the cap further defining a convex outer surface extending opposite the distribution cavity and a plurality of outlets extending generally perpendicular to the upper surface and through the cap from the distribution cavity to the exterior surface, the outlets being distributed over the entire exterior surface by being arranged in a plurality of concentric rings including an innermost ring, an outermost ring and a plurality of intermediate rings, wherein adjacent ones of the outlets in the outermost ring and the plurality of intermediate rings are spaced apart in a tangential direction around the outer periphery by the same distance; and

a grate disposed above the burner and supported along a portion of the upper surface.

19. The cooking appliance of claim 18 , wherein the plurality of concentric rings are arranged in a first group and a second group, the first group including the outermost ring and being more closely spaced in a radial direction than the second group, which includes the innermost ring.

20. The cooking appliance of claim 18 , wherein:
the base defines a fuel-air mix inlet and a mixing chamber, the mixing chamber being in communication with the fuel-air mix inlet and with the distribution cavity remote from the fuel-air mix inlet and further being separated from a portion of the distribution cavity;
the base includes an inner wall spaced inward from the outer periphery and defining a portion of the mixing chamber surrounding the distribution cavity; and
the mixing chamber is open to the distribution cavity through a plurality of ports extending through the wall.
