Abstract

A mechanism for raising and lowering a cooking surface within a recessed combustion chamber is provided.

Claims (21)

1. A cooking system comprising:

a heating apparatus comprising a recessed combustion chamber for receiving a combustible fuel, the recessed combustion chamber comprising a floor and an opening;

a cooking surface comprising a first hole, a second hole, and a planar surface substantially parallel to the floor;

a handle operably associated with the cooking surface;

a friction rod having a distal end near the floor and a proximate end near the opening, the friction rod passing through the first hole;

a guide rod running parallel to the friction rod and passing through the second hole of the cooking surface,

wherein friction between the friction rod and the cooking surface support the cooking surface above and substantially parallel to the floor, and

wherein rotation of a portion of the cooking surface toward the opening reduces the friction between the friction rod and cooking surface such that the cooking surface can be raised or lowered relative to the floor along the path of the guide rod.

2. The cooking system of claim 1 wherein the cooking surface is only in contact with the heating apparatus via the friction rod.

3. The cooking system of claim 1 wherein the friction between the friction rod and the cooking surface provides the only support for the cooking surface relative to the floor.

4. The cooking system of claim 1 wherein the handle is coupled to the cooking surface.

5. The cooking system of claim 4 wherein the handle is operably associated with the cooking surface to perform the rotation of the cooking surface toward the opening.

6. The cooking system of claim 4 wherein the handle is further operably associated with the cooking surface to raise the cooking surface, relative to the floor, along the friction rod.

7. The cooking system of claim 1 wherein the cooking surface comprises a third hole, the system further comprising a second friction rod having a distal end near the floor and a proximate end near the opening, the second friction rod passing through the third hole.

8. The cooking system of claim 1 further comprising a temperature sensor on the cooking surface.

9. The cooking system of claim 1 wherein the friction rod comprises one or more notches operable to associate with the first hole to position the cooking surface at one or more preset heights relative to the floor.

10. The cooking system of claim 1 wherein the heating apparatus further comprises at least one wall.

11. The cooking system of claim 10 wherein a portion of the at least one wall is transparent.

12. The cooking system of claim 1 wherein the heating apparatus further comprises a catalytic converter for reducing emissions from the combustion chamber.

13. The cooking system of claim 1 wherein said heating appliance includes an air inlet for supplying air to an inside of said chamber for combusting said combustible fuel.

14. The cooking system of claim 1 wherein the second hole is larger than the first hole such that the guide rod does not interfere with the support function of the friction rod.
