Abstract

A device for directing heat from a heat source in a barbecue grill to food on a rotisserie. The heat directing device has a base portion for placement over a heat source and a hollow duct extending from the base portion which terminates in an opening directed at the rotisserie. In one embodiment, there are two oppositely positioned ducts to direct heat to both the front and back of the food to be cooked. In another embodiment, there are louvers in the base portion so as to allow some heat to escape the base portion and cook the food from the underside. The base portion and duct are adjustable in a lateral manner to fit various sizes of barbecue grill bases. The heat directing device is especially suited for a gas fired barbecue grill unit.

Claims

1. A high efficiency barbecue grill for use in conjunction with a rotisserie wherein said grill has a base member with supporting side walls, said grill comprising;

a heat source supported by said base member;

a rotisserie supported by said side walls; and

a heat directing device including a substantially flat base portion positioned and extending over said heat source, said base portion constructed and arranged to provide heat confinement and vaporization of meat juices and fats and a hollow duct portion on at least one portion of said base portion offset from said rotisserie extending upwardly from said base portion and in the direction of said rotisserie, said duct portion terminating in an opening constructed and arranged to direct heat from said heat source toward said rotisserie such that heat flows laterally over and above said base portion.

2. The barbecue grill as defined in claim 1 wherein said base portion includes a floor member with side walls and lateral flanges extending therefrom.

3. The barbecue grill as defined in claim 2 wherein said floor member includes vent holes.

4. The barbecue grill as defined in claim 2 wherein said floor member includes louvers.

5. The barbecue grill as defined in claim 1 wherein said heat directing device is formed in at least two telescoping sections, said telescoping sections constructed and arranged to provide adjustment.

6. The barbecue grill as defined in claim 1 wherein said heat source is a gas burner and said directing device is composed of stainless steel.

7. The barbecue grill as defined in claim 1 wherein said heat source is a gas burner and said directing device is composed of porcelain coated metal.

8. The barbecue grill as defined in claim 1 wherein said hollow duct portion is connected to said base portion by an arcuate section and said opening in said duct portion is elongated.

9. A high efficiency barbecue grill for use in conjunction with a rotisserie wherein said grill has a base member with supporting side walls, said grill comprising;

a heat source supported by said base member;

a rotisserie supported by said side walls; and

a heat directing device including a base portion positioned over said heat source and a first hollow duct portion extending from said base portion, said duct portion terminating in an opening constructed and arranged to direct heat from said heat source in the direction of said rotisserie; and

a second hollow duct portion positioned opposite said first hollow duct portion and extending from said base portion, said second hollow duct portion terminating in an opening constructed and arranged to direct heat from said heat source in the direction of said rotisserie and opposite said first hollow portion.

10. The barbecue grill as defined in claim 9 wherein said opening of said first hollow duct portion extends a greater distance from said base portion than said second duct portion.

11. A heat directing device for use in a barbecue grill, said grill having a heat source and a rotisserie supported by a base member of said grill, said heat directing device comprising:

a substantially flat base portion adapted to be positioned and extended over said heat source and placed directly in contact with said grill, said base portion constructed and arranged to provide heat confinement and vaporization of meat juices and fats and a hollow duct portion positioned on at least one portion of said base portion and offset from said rotisserie when said base portion is placed on said grill, said base portion extending upwardly from said base portion, said duct portion terminating in an opening constructed and arranged to direct heat from said heat source in the direction of said rotisserie when said heat directing device is placed on said grill such that heat flows laterally over and above said base portion.

12. The heat directing device as defined in claim 11 wherein said base portion includes a floor member with side walls and lateral flanges extending therefrom.

13. The heat directing device as defined in claim 12 wherein said floor member includes vent holes.

14. The heat directing device as defined in claim 12 wherein said floor member includes louvers.

15. The heat directing device as defined in claim 11 wherein said heat directing device is formed in at least two telescoping sections, said telescoping sections constructed and arranged to provide adjustment.

16. The heat directing device as defined in claim 11 wherein said heat source is a gas burner and said directing device is composed of stainless steel.

17. The heat directing device as defined in claim 11 wherein said heat source is a gas burner and said directing device is composed of porcelain coated metal.

18. The heat directing device as defined in claim 11 wherein said hollow duct portion is connected to said base portion by an arcuate section and said opening in said duct portion is elongated.

19. A heat directing device for use in a barbecue grill, said grill having heat source and a rotisserie supported by a base member of said grill, said heat directing device comprising:

a substantially flat base portion adapted to be positioned and extended over said heat source and placed directly in contact with said grill, said base portion constructed and arranged to provide heat confinement and vaporization of meat juices and fats and a first hollow duct portion positioned on one portion of said base portion extending upwardly from said base portion, said duct portion terminating in an opening constructed and arranged to direct heat from said heat source in the direction of said rotisserie; and

a second hollow duct portion positioned of said base portion opposite said first hollow duct portion and extending upwardly from said base portion, said second hollow duct portion terminating in an opening constructed and arranged to direct heat from said heat source in the direction of said rotisserie and opposite said first hollow duct portion.

20. The heat directing device as defined in claim 19 wherein said opening of said first hollow duct portion extends a greater distance from said base portion than said second duct portion.
