Abstract
A portable solar oven which innovatively combines improved elements to achieve and maintain a high internal temperature. In the shown embodiment, a box-shaped insulated body shell includes a pair of side walls, a front wall, a back wall, and a base. The front wall has an insulated door made integral therewith. The inner portion of the side walls and door have polished metal panels affixed thereto to reflect solar radiation into the interior of the oven. The back wall and base have a heat element disposed thereon for collecting direct and reflected solar radiation, thereby maintaining a high constant temperature in the interior of the oven. A transparent top wall of dual pane tempered glass is permanently affixed to the topmost portion of the body shell. A reflective cover is rotatably affixed to either side of the body shell using a pair of toothed washers. The reflective cover reflects additional solar radiation into the inner portion of the oven.
