Food cooking oven

A food cooking oven which comprises:

• a. exterior side, bottom, top and back walls;
• b. a door closing the front of said oven;
• c. an interior back wall and electrically conductive and interconnected interior side, bottom and top walls, said interior walls being spaced inwardly from said exterior walls, said interior and exterior walls together defining a substantially rigid, self-supporting structure, said interior walls defining a volume of at least, approximately, 0.25 cubic feet;
• d. thermal and electric insulation means disposed between said interior and exterior walls;
• and
• e. a pair of rigid, spaced apart, electrical contact members, said contact members being secured to and in electrical contact with at least one of said interior walls and extending along a substantial portion of the depth of said oven and extending outwardly through and beyond the adjacent exterior wall, each of said contact members being adapted to be received within a respective one of a pair of clamps which are connected to a low voltage, high current power supply whereby a non-hazardous, low voltage is impressed across said contacts and thereby an electrical current flows through said interior walls in an amount sufficient to heat the interior of said oven to a food cooking temperature.

A food cooking apparatus which comprises:

• a. a food cooking oven comprising,
• i. exterior side, bottom, top and back walls,
• ii. a thermally insulated door closing the front of said oven,
• iii. interior walls spaced inwardly from said exterior walls and defining the interior of said oven, said oven interior having a volume of at least, approximately, 0.25 cubic feet, said exterior and interior walls together defining a substantially rigid, self-supporting structure,
• iv. thermal and electric insulation means disposed between said interior and exterior walls, and
• v. a pair of rigid, spaced apart, electrical contact members, said contact members being secured to and in electrical contact with at least one of said interior walls and extending along a substantial portion of the depth of said oven and extending outwardly through and beyond the adjacent exterior wall,
• b. a power supply unit disposed beneath said food cooking oven, said power supply unit comprising,
• i. a frame,
• ii. a pair of clamps mounted on said frame, each of said electrical contact members being disposed within a respective one of said clamps, and
• iii. means connected to said clamps for impressing across said clamps a low, non-hazardous voltage whereby, in response to said voltage, an electrical current flows through said oven in an amount sufficient to heat the interior of said oven to a food cooking temperature.
