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 functions as a
radiant heat shield which is operator movable to either
expose to or occlude from the oven cooking chamber to
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 for 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.
