1. Field of the Invention
The invention relates to a portable, self-contained solar cooking stove which is foldable into a neat compact unit, easily stored and quickly unfolded and assembled for use for solar cooking. The stove may be economically produced from paper cardboard and foil.
2. Description of the Prior Art
Solar stoves known in the prior art are provided with an open top box form oven, with petal shaped reflector panels extending upwardly from the oven. As shown in U.S. Pat. No. 3,898,786, ten of such petal form reflector panels were required to surround the oven and reflect solar heat into the oven. For folding the prior art structure into a compact unit for storage, the petal form reflector panels have not functioned as well as is possible with the reflector panels of the present invention.
In the prior art, it has been necessary to provide a hole in the window element covering the oven, said hole serving to receive a pin mounted vertically in the hole to be aligned with the sun by orienting the solar stove until the pin does not cast a shadow.
One of the objects of the invention is to improve the reflector panel constructions over the prior art, and another object is to eliminate the need for drilling a hole in the oven cover to receive the pin required in the prior art arrangement.
Another object is to provide an improved and novel oven construction.
