Solar cooking apparatus

摘要

The present invention relates to a solar cooking apparatus, comprising: a first solar reflector; a second solar reflector; a solar collection element; and a solar collection element holder, wherein the first solar reflector and the second solar reflector are concave, and opposably arranged and aligned with a solar collection element axis, each reflector having a range of motion on a plane perpendicular to the solar collection element axis, and focusing radiation at the solar collection element, which rapidly heats when the first and/or second solar reflectors are in an opened position, the first and second solar reflectors protectably encase the solar collector when in a closed position. The solar cooking apparatus is adjustable and, in some embodiments, portable.

1. A solar cooking apparatus, comprising:
a first solar reflector; a second solar reflector; a solar collection element, comprising an inner tube having an inner tube diameter, an inner tube length, an inner tube open end, an inner tube closed end, an interior surface enclosing an interior space, and an exterior surface, the interior and exterior surfaces extending the inner tube length, wherein the exterior surface comprises one or more layers consisting essentially of aluminumnitrile/aluminum, aluminum-nitrile/stainless steel/copper, or borosilicate/aluminum/stainless steel/copper, and the outer tube having an outer tube diameter, an outer tube length, an outer tube open end, an outer tube closed end, and a barium getter, wherein the outer tube diameter and the outer tube length are both greater than the inner tube diameter and the inner tube length, wherein the inner tube is fixed inside of the outer tube and sealed between the inner open end and outer tube open end to form a hollow space extending the length of the exterior tube under vacuum pressure between the exterior wall of the inner tube and the outer tube; a solar collection element holder, wherein the first solar reflector and the second solar reflector are concave and parabolic, and are in a substantially symmetrical arrangement to a solar collection element axis, each reflector having a range of motion upon a solar reflector hinge on a plane perpendicular to the solar collection element axis, to focus solar radiation at the solar collection element from a reflective surface when the first or second solar reflectors are in an opened position, the first and second solar reflectors protectably encase the solar collector when in a closed position, the solar reflector hinge is mounted upon a bracket aligned with the solar element axis that allows for the solar cooking apparatus to rotate on a horizontal plane parallel to the ground when the solar cooking apparatus is in an unfolded standing position; a cooking implement that fits within the inner tube, having a length less than or equal to the inner tube length and an open trough configuration; a cleaning implement that is attachable to a first cooking implement end; and a foldable stand to put the solar cooking apparatus in a horizontal orientation for use when the foldable stand is in the unfolded standing position, comprising two curved legs having a contour that follows the first and second solar reflectors in the closed position and form a handle when two curved legs are in a folded position.
