ABSTRACT:
An all-metal, hand-portable, light-weight heating device serves as a self-contained oven, as a stove, or as a space heater. The box-like device comprises hollow sheet-metal back, side and top walls and door. A fully enclosed heater chamber beneath the oven enclosure includes a removable, slide-in top closure plate, which channels hot air to the interior of the hollow walls when used as an oven or space heater; removal of the closure plate enables use of the device as a stove. A second embodiment has a foldable stove top hinged to the side of the device. The preferred material is sheet aluminum. A portable gas bottle can be used as the fuel supply. Excess secondary air is available, induced by the operation of the gas burner. This induced flow of cool air creates a high thermal gradient between the inner and the outer heated wall surfaces, so that the outer surfaces of the device operate at a safe, non-searing temperature. The device can be used for camping, cook-outs, or for emergency situations, or for household use as a regular oven or stove in third world communities.
