Abstract

A combustion cooker with an integrated and optionally removable thermoelectric generator and methods for making and using the same. The combustion cooker can include a fire basket that comprises a bottom region and a lateral region that is coupled with the bottom region and that defines a central combustion chamber. Being disposed about a periphery of the fire basket, the thermoelectric generator can include a cold side heat sink and a hot side heat sink. The cold side heat sink can be cooled via exterior air available outside the housing; whereas, the hot side heat sink can be in direct thermal communication with the periphery of the fire basket. Thereby, the thermoelectric generator advantageously can generate electrical power based upon a thermal differential between the cold side heat sink and the hot side heat sink.

Claims

1. A combustion device, comprising:

a housing;

a fire basket being disposed within said housing and comprising a bottom region and a lateral region being coupled with the bottom region and defining a central combustion chamber; and

a thermoelectric generator being disposed about a periphery of said fire basket and comprising a cold side heat sink being cooled via exterior air available outside said housing and a hot side heat sink being in direct thermal communication with the periphery of said fire basket,

wherein said thermoelectric generator generates electrical power based upon a thermal differential between the cold side heat sink and the hot side heat sink.

2. The combustion device of claim 1, wherein said thermoelectric generator comprises a plurality of thermoelectric generators for generating the electrical power, each of said thermoelectric generators being disposed at the periphery of said fire basket and comprising the cold side heat sink and the hot side heat sink.

3. The combustion device of claim 2, wherein the hot side heat sinks of said thermoelectric generators communicate with the central combustion chamber via respective openings formed in the periphery of said fire basket.

4. The combustion device of claim 3, wherein the periphery of said fire basket forms each of the openings with a shape that corresponds with a shape of the hot side heat sink of a relevant thermoelectric generator.

5. The combustion device of claim 1, wherein said thermoelectric generator extends between said housing and said fire basket.

6. The combustion device of claim 5, wherein the hot side heat sink of said thermoelectric generator does not extend into the central combustion chamber.

7. The combustion device of claim 6, wherein said fire basket is removably disposed within said housing.

8. The combustion device of claim 5, wherein said housing defines a vent opening for cooperating with the cold side heat sink of said thermoelectric generator.

9. The combustion device of claim 8, wherein said housing receives the exterior air for cooling the cold side heat sink of said thermoelectric generator via the vent opening.

10. The combustion device of claim 1, further comprising an electric fan for drawing the exterior air into said housing and onto the cold side heat sink of said thermoelectric generator.

11. The combustion device of claim 10, wherein said electric fan draws the exterior air from outside said housing into the combustion chamber.

12. The combustion device of claim 10, wherein said thermoelectric generator provides the electrical power for operating said electric fan.

13. The combustion device of claim 10, wherein said housing comprises an inner housing for receiving said fire basket and an outer housing being disposed about said inner housing and defining an air gap therebetween, said electric fan drawing the exterior air from outside said outer housing into the air gap for cooling the cold side heat sink of said thermoelectric generator.

14. The combustion device of claim 1, wherein said fire basket comprises a cooker top region being opposite the bottom region and defining a chimney opening in communication with the central combustion chamber.

15. The combustion device of claim 14, wherein the cooker top region is capable of supporting a cooking ring.

16. The combustion device of claim 15, wherein the cooking ring forms a central opening that communicates with the chimney opening defined by the cooker top region.

17. The combustion device of claim 14, wherein the cooker top region includes a support member extending from the lateral region, the support member for engaging said housing and supporting said fire basket.

18. The combustion device of claim 1, further comprising a power outlet for coupling with a peripheral device and providing the electrical power generated by said thermoelectric generator to the coupled peripheral device.

19. The combustion device of claim 18, said power outlet comprises one or more Universal Serial Bus connectors.
