FIELD: personal use articles.

SUBSTANCE: sun-ray collector - vacuum flask accumulator relates to devices that apply sun thermal energy to heat water, boil food, bake bread, etc. The sun-ray collector includes a vacuum flask accumulator, which comprises a body with double walls and an internal heat insulation, a cover, a bottom with the possibility of disconnection. The body is made with the possibility to place a boiling reservoir in it, the cover of which is equipped with a gate and a valve. In the upper part of the body there is a power plant, which consists of converging lenses with rims fixed on the screen panel made of a copper sheet, as a result of which the sun-ray energy is converted into high-degree thermal energy. Branches in the form of copper tapes coated with incombustible heat insulation are welded to the copper sheet of the vacuum flask accumulator, as a result of which heat losses of the boiling reservoir during cooking are reduced.

EFFECT: provision of possibility to keep food in hot condition.
