Portable forced draft cooker

Claim 1

A portable forced draft solid fuel burning cooker that includes: a. a hollow duct defining elongate base having a top piece, said top piece having a central opening therein, and first and second openings on opposite sides of said central opening; b. an electrically operated blower assembly mounted on said top piece, said blower assembly when electrically energized directing a stream of air through said central opening into the interior of said base; c. manually operated switch means for turning said blower assembly on and off; d. first and second pivotally supported dampers inside said base and intermediately disposed between said central opening and first and second openings for controlling the quantity of air flowing to said first and second openings when said blower assembly is electrically energized; e. first and second heater assemblies mounted on said top piece above said first and second openings, each of said heater assemblies including an outer cylindrical shell secured to said top piece and in communication with the one of said first and second openings most adjacent thereto, a second inner cup shaped shell in which solid fuel is disposed, a ring that joins free peripheral edges of said first and second shells, said second shell of substantially less transverse area than said first shell and said first and second shells cooperating with said ring to define a confined space of annulus shape, a third cup shaped shell interposed in a fixed position between said first and second shells that subdivides said confined space into an outer first passage and an inner second passage in which air flowing thereto from said blower assembly is preheated by the combustion of said fuel prior to discharging across said fuel from a plurality of spaced openings in said second shell to support the combustion of said fuel, and first means for supporting said third cup shaped shell in a fixed position between said first and second shells; and f. first and second handles operatively associated with said first and second dampers to control the position of the latter and regulate the quantity of air flowing from said blower assembly to said first and second heater assemblies.
