Abstract

The grill has separately adjustable left and right grill surfaces and independently controllable left and right burner portions. A removable heat shield impedes heat transfer between the left and right sides, to permit different cooking temperatures at the same time. A slotted heat distribution plate minimizes hot spots on the grill surface while allowing a controlled flare-up to enhance the barbecue flavor.

Claims

1. A barbecue grill comprising:

a lower containment means;

an open flame gas burning heat source disposed in said containment means;

a heat distribution plate disposed generally above said heat source and within said lower containment means;

a cooking grid supported on said lower containment means and disposed generally above said heat distribution plate, said cooking grid providing a cooking surface which defines a generally horizontal plane for supporting food being cooked and having a plurality of openings through which liquified fats may drip during cooking;

said heat distribution plate comprising a heat conducting metal sheet which has a midportion and at least two opposing edges which are spaced from said lower containment means and which are upwardly and outwardly flared such that said opposing edges are closer to said cooking grid than the midportion of said heat distribution plate;

said heat distribution plate being operable to conduct heat from said midportion to said opposing edges and thereby tending to distribute heat relatively uniformly to said cooking grid.

2. The grill of claim 1 wherein said heat distribution plate comprises at least one stamped sheet metal plate.

3. The grill of claim 1 wherein said heat distribution plate comprises two separate sheet metal plates.

4. The grill of claim 3 wherein said two separate sheet metal plates define mirror images of one another.

5. The grill of claim 1 wherein said heat distribution plate defines a generally rectangular shape and wherein said opposing edges are parallel with the widthwise dimension of said rectangular shape.

6. The grill of claim 1 wherein said lower containment means has sidewalls and wherein the periphery of said heat distribution plate is spaced away from the sidewalls of said lower containment means.

7. A barbecue grill comprising:

a lower containment means;

an open flame gas burning heat source disposed in said containment means;

a heat distributin plate disposed generally above said heat source and within said lower containment means;

a cooking grid supported on said lower containment means and disposed generally above said heat distribution plate, said cooking grid providing a cooking surface which defines a generally horizontal plane for supporting food being cooked and having a plurality of openings through which liquified fats may drip during cooking;

said heat distribution plate comprising a heat conducting metal sheet which has a midportion and at least two opposing edges which are spaced from said lower containment means and which are upwardly and outwardly flared such that said opposing edges are closer to said cooking grid than the midportion of said heat distribution plate;

said heat distribution plate having a plurality of apertures therein;

said heat distribution plate being operable to conduct heat from said midportion to said opposing edges and thereby tending to distribute heat relatively uniformly to said cooking grid; and

said apertures in said heat distribution plate being so adapted and arranged to permit a controlled flare-up by ignition of fat dripping whereby grilled flavor is imparted to the food being cooked.

8. The grill of claim 7 wherein said heat distribution plate comprises at least one stamped sheet metal plate.

9. The grill of claim 7 wherein said heat distribution plate comprises two separate sheet metal plates.

10. The grill of claim 9 wherein said two separate sheet metal plates define mirror images of one another.

11. The grill of claim 7 wherein said heat distribution plate defines a generally rectangualr shape and wherein said opposing edges are parallel with the widthwise dimension of said rectangular shape.

12. The grill of claim 7 wherein said lower containment means has sidewalls and wherein the periphery of said heat distribution plate is spaced away from the sidewalls of said lower containment means.

13. The grill of claim 7 wherein at least some of said apertures comprise elongated slots.

14. The grill of claim 7 wherein said heat distribution plate comprises at least one stamped sheet metal plate and wherein said apertures are formed by stamping.

15. A bargecue grill comprising:

a lower containment means;

an open flame gas burning heat source disposed in said containment means;

a heat distribution plate disposed generally above said heat source and within said lower containment means;

a cooking grid supported on said lower containment means and disposed generally above said heat distribution plate, said cooking grid providing a cooking surface which defines a generally horizontal plane for supporting food being cooked and having a plurality of openings through which liquified fats may drip during cooking;

said heat distribution plate comprising a heat conducting metal sheet which has a midportion and at least two opposing edges which are spaced from said lower containment means and which are upwardly and outwardly flared such that said opposing edges are closer to said cooking grid than the midportion of said heat distribution plate;

said heat distribution plate having a plurality of apertures therein;

said heat distribution plate being operable to conduct heat from said midportion to said opposing edges and thereby tending to distribute heat relatively uniformly to said cooking grid; and

said appertures in said heat distribution plate defining an area less than about 15% of the area defined by said heat distribution plate and being so adapted and arranged to permit a controlled flare-up by ignition of fat dripping whereby grilled flavor is imparted to the food being cooked.

16. The grill of claim 15 wherein said heat distribution plate comprises at least one stamped sheet metal plate.

17. The grill of claim 15 wherein said heat distribution plate comprises two separate sheet metal plates.

18. The grill of claim 17 wherein said two separate sheet metal plates define mirror images of one another.

19. The grill of claim 15 wherein said heat distribution plate defines a generally rectangular shape and wherein said opposing edges are parallel with the widthwise dimension of said rectangular shape.

20. The grill of claim 15 wherein said lower containment means has sidewalls and wherein the periphery of said heat distribution plate is spaced away from the sidewalls of said lower containment means.

21. The grill of claim 15 wherein at least some of said apertures comprise elongated slots.

22. The grill of claim 15 wherein said heat distribution plate comprises at least one stamped sheet metal plate and wherein said apertures are formed by stamping.
