SELF-CONTAINED ENERGY-EFFECTIVE SOLAR COOKING STOVE Russian patent published in 2015 - IPC F24J2/02 

FIELD: power industry.

SUBSTANCE: self-contained energy-effective solar cooking stove (SESCS) relates to renewable energy sources, namely to direct use of energy of solar radiation beams for preparation and heating of food under field and stationary conditions. SESCS can be used in summer camps, transport cafes, cottages, detached houses in countryside, mountain villages, at different remote facilities, etc. SESCS includes a movable support and a light-guide tube located on it and provided with an optically active dome consisting of a convex plane lens and longitudinal convex plane section lenses, which are connected to each other; a paraboloid concentrator is located at a certain angle α inside the light-guide tube in its lower part; a longitudinal reflector of a paraboloid profile in the cross section and located opposite the optically active dome in the upper part of the light-guide tube; a hollow spherical cooking stove consisting of a housing having the shape of a hollow flattened sphere, the inner surface of which is coated with heat reflecting foil, and its cavity is filled with heat accumulating material, for example paraffin 46-48, as well as it includes a hollow cover plate having a spherical shape, its internal cavity is also filled with heat accumulating material (paraffin 46-48); a conical hole is located in the stove housing on the side of the parabolic concentrator.

EFFECT: self-sustained energy-efficient solar cooking stove requires no tracking of the sun; it is easy to operate, it has high efficiency of direct conversion of solar radiation to heat energy.
