Abstract

A gas burner having a combustion chamber with a bottom and a circumferential wall. A plurality of fuel exit ports are disposed in the circumferential wall, and are directed generally inwardly toward the combustion chamber and upwardly from the bottom of the combustion chamber. The fuel exit ports are preferably directed inwardly at an angle that is slightly rotated from a central axis of the burner to create a swirling flame. A plurality of secondary air inlets extend through the bottom of the combustion chamber. An injector orifice is aligned with the central axis of the burner. The injector orifice is secured to the cooktop using a bracket, which has an orifice-securing surface, with two sidewalls extending therefrom and terminating in fastening flanges. The fastening flanges have asymmetrically arranged slots therein to receive tabs extending from the burner to ensure proper alignment of the burner and the injector orifice.

First claim

What is claimed is:

1. A bracket to secure an injector orifice to a cooktop, comprising:
an orifice-securing surface;
a first sidewall extending generally orthogonally from a first edge of the orifice-securing surface and terminating in a first fastening flange;
a second sidewall extending generally orthogonally from a second edge of the orifice-securing surface and terminating in a second fastening flange; and
a plurality of burner locating slots formed in the first fastening flange and the second fastening flange, wherein the plurality of burner locating slots are asymmetrically distributed and are further defined within the first and second sidewalls, respectively, and wherein the plurality of burner locating slots are configured to directly receive a burner having a plurality of tabs in only one rotational orientation with respect to the orifice-securing surface.

2. The bracket of claim 1 , wherein the first fastening flange extends generally perpendicularly outwardly from the first sidewall, and wherein the second fastening flange extends generally perpendicularly outwardly from the second sidewall.

3. The bracket of claim 2 , having a greater number of burner locating slots in the first fastening flange and the first sidewall than in the second fastening flange and the second sidewall.

4. The bracket of claim 1 , wherein the orifice-securing surface is generally parallel to the cooktop, and wherein the injector orifice is aligned with a central axis of a burner aperture on the cooktop when it is secured with the bracket, wherein at least one burner locating slot of the plurality of burner locating slots is in an offset position with respect to the central axis.

5. The bracket of claim 1 , wherein the orifice-securing surface, the first and second sidewalls and the first and second fastening flanges are defined within a single continuous plate, and wherein the plurality of burner locating slots are integrally defined at least within a surface of the single continuous plate at the first and second fastening flanges.

6. The bracket of claim 5 , wherein the plurality of burner locating slots extend at least partially into the first and second sidewalls.

7. The bracket of claim 6 , wherein the plurality of burner locating slots are defined by apertures that extend at least partially through the first and second fastening flanges and the first and second sidewalls, respectively.

8. The bracket of claim 1 , wherein the first fastening flange includes two burner locating slots, and wherein the second fastening flange includes one burner locating slot.

9. The bracket of claim 1 , wherein each of the burner locating slots defined within the first fastening flange are out of axial alignment with each of the burner locating slots defined within the second fastening flange.

10. A bracket to secure a gas burner to a cooktop, the bracket comprising:
an orifice-securing surface;
first and second fastening flanges that are positioned parallel with and offset from the orifice-securing surface, wherein the first and second fastening flanges define a plurality of burner locating slots, and wherein the plurality of burner locating slots are asymmetrically distributed within the first and second fastening flanges;
a burner having a stem that is selectively coupled to the first and second fastening flanges; and
a plurality of tabs that extend outward from the stem, wherein each tab of the stem selectively and directly engages only one corresponding burner locating slot of the plurality of burner locating slots, wherein engagement of the plurality of tabs with the plurality of burner locating slots defines only one angular orientation of the burner with respect to the first and second fastening flanges.

11. The bracket of claim 10 , wherein the plurality of tabs of the stem are positioned in an asymmetrical configuration.

12. The bracket of claim 11 , wherein the plurality of burner locating slots of the first and second fastening flanges matches the asymmetrical configuration of the plurality of tabs of the stem to define a single engaged position of the burner within the first and second fastening flanges.

13. The bracket of claim 10 , wherein the first fastening flange has a first number of burner locating slots defined therein and the second fastening flange has a second number of burner locating slots defined therein, wherein the first number of burner locating slots is greater than the second number of burner locating slots.

14. The bracket of claim 10 , wherein the orifice-securing surface is generally parallel to the cooktop, and wherein an injector orifice is aligned with a central axis of a burner aperture on the cooktop when it is secured with the bracket.

15. The bracket of claim 10 , wherein the plurality of burner locating slots are integrally defined at least within the first and second fastening flanges.

16. The bracket of claim 10 , wherein at least one tab of the plurality of tabs extends outward from the stem in an offset configuration that is free of alignment with a central axis of the burner.

17. A bracket to secure a gas burner to a cooktop, the bracket comprising:
an orifice-securing surface;
first and second fastening flanges that are positioned parallel with and offset from the orifice-securing surface, wherein the first and second fastening flanges define a plurality of burner locating slots, and wherein the plurality of burner locating slots are positioned in an asymmetrical configuration; and
a plurality of tabs that extend outward from a stem of a burner, wherein each tab selectively engages only one corresponding burner locating slot of the plurality of burner locating slots, and wherein each tab is free of engagement within the remaining burner locating slots.

18. The bracket of claim 17 , wherein engagement of the plurality of tabs with the plurality of burner locating slots defines only one angular orientation of the burner with respect to the first and second fastening flanges.

19. The bracket of claim 17 , wherein at least one tab of the plurality of tabs extends outward from the stem in an offset configuration that is free of alignment with a central axis of the burner.

20. The bracket of claim 17 , wherein the plurality of burner locating slots are integrally defined at least within the first and second fastening flanges.
