Abstract

Provided is a broil burner including a generally-tubular gas conduit configured to extend between a rearward region of an oven cavity and a forward region of the oven cavity. The gas conduit includes an inlet that cooperates with a gas source to convey a combustible gas from the gas source to the gas conduit, and a plurality of apertures through which the combustible gas exits the gas conduit to be combusted. A reflector is provided, and extends between opposing segments of the gas conduit to reflect heat generated by combustion of the combustible gas in a downward direction, generally toward a central region of the oven cavity.

First claim

What is claimed is:

1. A broil burner comprising:
a generally-tubular gas conduit configured to extend between a rearward region of an oven cavity and a forward region of the oven cavity, the gas conduit including two laterally spaced apart segments that define an open region between the two laterally spaced apart segments and an inlet that cooperates with a gas source to convey a combustible gas from the gas source to the gas conduit including the two laterally spaced apart segments, and a plurality of apertures through which the combustible gas exits the gas conduit to be combusted in the open region; and
a reflector that extends over the two laterally spaced apart segments of the gas conduit and over the entire open region to reflect heat generated by combustion of the combustible gas in a downward direction, generally toward a central region of the oven cavity, the reflector extending an increasingly greater distance above the open region from each laterally spaced apart segment to a center of the open region.

2. The broil burner of claim 1 further comprising a mounting leg for suspending the broil burner adjacent to a ceiling of the oven cavity.

3. The broil burner of claim 1 , wherein the inlet is arranged along the gas conduit to cooperate with the gas source adjacent to the rearward region of the oven cavity.

4. The broil burner of claim 1 , wherein the gas conduit comprises a generally U-shaped configuration in which the two laterally spaced apart segments are joined together by a joining region that establishes fluid communication between the two laterally spaced apart segments.

5. The broil burner of claim 1 , wherein the reflector and the gas conduit are coupled together by a releasable mechanical fastener.

6. A broil burner comprising:
a generally-tubular gas conduit configured to extend between a rearward region of an oven cavity and a forward region of the oven cavity, the gas conduit comprising an inlet that cooperates with a gas source to convey a combustible gas from the gas source to the gas conduit and a plurality of apertures through which the combustible gas exits the gas conduit to be combusted; and
a reflector that extends between opposing lateral segments of the gas conduit to reflect heat generated by combustion of the combustible gas in a downward direction, generally toward a central region of the oven cavity,
a grille formed within a central region of the reflector between the opposing segments of the gas conduit; and
a flash tube that extends between the gas conduit and the grille to convey a portion of the combustible gas introduced to the gas conduit through the inlet to the grille, where the portion of the combustible gas is to be combusted.

7. The broil burner of claim 6 , wherein the grille comprises a plurality of arcuate members spaced apart from each other to form apertures through which heat generated by combustion of the combustible gas at the grille is to be radiated downward, generally toward the central region of the oven cavity.

8. The broil burner of claim 7 , wherein the arcuate members comprise a substantially semi-cylindrical shape, extending downward from the reflector to extend generally toward the central region of the oven cavity when the broil burner is installed.

9. The broil burner of claim 6 , wherein an interior dimension of the flash tube is less than an interior dimension of the gas conduit.

10. The broil burner of claim 1 , wherein portions of the reflector adjacent to the two laterally spaced apart segments are arranged vertically above the apertures in the two laterally spaced apart segments so a flame ring formed by combustion of the combustible gas exiting the apertures in the two laterally spaced apart segments is arranged closer to the central region of the oven cavity than the portions of the reflector.

11. A cooking apparatus comprising:
an oven cavity in which a food item is to be received and cooked;
a bake burner arranged adjacent to a floor of the oven cavity, the bake burner being operable to generate heat for elevating a temperature within the oven cavity; and
a broil burner that is arranged adjacent to a ceiling of the oven cavity and operable independently of the bake burner to generate heat for elevating the temperature in the oven cavity, the broil burner comprising:
a generally-tubular gas conduit configured to extend between a rearward region of the oven cavity and a forward region of the oven cavity, the gas conduit including two laterally spaced apart segments that define an open region between the two laterally spaced apart segments and comprising an inlet that cooperates with a gas source to convey a combustible gas from the gas source to the gas conduit including the two laterally spaced apart segments, and a plurality of apertures in the two laterally spaced apart segments through which the combustible gas exits the gas conduit to be combusted in the open region, and
a reflector that extends over the two laterally spaced apart segments of the gas conduit and over the entire open region to reflect heat generated by combustion of the combustible gas in a downward direction, generally toward a central region of the oven cavity, the reflector extending an increasingly greater distance above the open region from each laterally spaced apart segment to the center of the open region.

12. The cooking apparatus of claim 11 further comprising a mounting leg that cooperates with the ceiling of the oven cavity to suspend the broil burner adjacent to the ceiling.

13. The cooking apparatus of claim 11 , wherein the inlet is arranged along the gas conduit to cooperate with the gas source adjacent to the rearward region of the oven cavity.

14. The cooking apparatus of claim 11 , wherein the gas conduit comprises a generally U-shaped configuration in which the two laterally spaced apart segments that are to extend forward from the rearward region of the oven cavity and a joining region establishes fluid communication between the two laterally spaced apart segments.

15. The cooking apparatus of claim 11 , wherein the reflector and the gas conduit are coupled together by a releasable mechanical fastener.

16. The cooking apparatus of claim 11 further comprising:
a grille formed within a central region of the reflector between the two laterally spaced apart segments of the gas conduit; and
a flash tube that extends between the gas conduit and the grille to convey a portion of the combustible gas introduced to the gas conduit through the inlet to the grille, where the portion of the combustible gas is to be combusted.

17. The cooking apparatus of claim 16 , wherein the grille comprises a plurality of arcuate members spaced apart from each other to form apertures through which heat generated by combustion of the combustible gas at the grille is to be radiated downward, generally toward the central region of the oven cavity.

18. The cooking apparatus of claim 17 , wherein the arcuate members comprise a substantially semi-cylindrical shape, extending downward from the reflector to extend generally toward the central region of the oven cavity when the broil burner is installed.

19. The cooking apparatus of claim 16 , wherein an interior dimension of the flash tube is less than an interior dimension of the gas conduit.

20. The cooking apparatus of claim 11 , wherein the portions of the reflector adjacent to the gas conduit are arranged vertically above the apertures in the two laterally spaced apart segments so a flame ring formed by combustion of the com
