A cooking structure which provide for two or more side-by-side ovens separated by vertical, movable, hinged partition(s) whereby the oven structure may function as one large oven or as two or more smaller independent ovens, wherein for each oven a tangential fan blows air substantially evenly over upper electrical heating elements strung generally from side-to-side of the oven, wherein a flow director (baffle) structure functions as a radiant heat shield which is operator movable to either expose to or occlude from the oven cooking chamber the direct radiation from its heating elements, depending on the need to roast, bake, or broil the food product. Also provided are lower electrical heating elements positioned below a ceramic cooking surface for ensuring evenness of radiant heat transfer therefrom. Also provided is operator controlled top vs. bottom heating using a slide control that reciprocally affects the duty cycle of the top and bottom electrical heating elements, further allowing precision baking control.

I claim: 1. A cooking structure having a single or side by side multiple ovens wherein each oven is formed with a cooking chamber adapted to be closed to outside fresh air during operation, each said oven comprising first wall means forming an inner housing, second wall means forming an outer housing spaced from said inner housing, each said housing comprising the structural wall portions of a ceiling, a floor, opposing sides, a back and a front, which wall portions enclose and seal the space between said first and second wall means to fresh outside air, heat insulating material in said space to provide a heat insulating barrier, said front structural portions forming an oven access perimeter structure against which an access door to said cooking chamber can be mounted, third wall means positioned within said inner housing and having an upper generally horizontal first wall section spaced downwardly from said ceiling of said inner housing and sealed at its front against said front wall portions, said third wall means further having a generally vertical rear second wall section spaced forwardly inwardly from said back wall portion of said inner housing, said first and second wall sections extending laterally across said cooking chamber and engaging said opposing sides, substantially flat surfaced, food item supporting plate means mounted within said inner housing and extending over a substantial portion of the floor of said inner housing for providing a heat sink and food item support and floor portion of said inner housing and forming a lower substantially sealed heating cavity, said first and second wall sections in conjunction with said first wall means and said plate means providing a captured air circulating duct which is sealed to outside fresh air and comprising a combination of an upper heating cavity communicating with a circulating air feed channel, wherein said structural portions of said inner housing, third wall means and plate means delimit and structurally define said cooking chamber, aperture means formed thru said horizontal first wall section to allow circulating captured air to flow therethrough down into said cooking chamber, recirculating captured air outlet gap means thru at least one of said supporting plate means or said second wall section of said third wall means for placing said cooking chamber and said captured air circulating duct into air flow communication, a first electrical resistance heating means positioned under said supporting plate means within said lower heating cavity, a second electrical resistance heating means positioned under said ceiling of said inner housing within said upper heating cavity, heat radiation shielding means positioned between said second electrical resistance heating means and said horizontal first wall section of said third wall means and being operator moveable with respect to said second electrical resistance heating means and said aperture means, between a heat radiation shielding position and a non-shielding position with respect to said cooking chamber, captured air flow circulating means communicating with said cooking chamber and said circulating air feed channel and adapted to circulate captured air from said cooking chamber into said circulating air feed channel, then into said upper heating cavity, then over said second electrical resistance heating means, then thru said aperture means down into said cooking chamber and across said supporting plate means, and then thru said air outlet gap means and back into said circulating air feed channel.
