Cooking appliance with conductive heating capabilities

An oven comprising:

• an oven body comprising an interior compartment defined by a top wall, a bottom wall, first and second side walls extending between the top wall and the bottom wall, a back wall, and a door panel;
• a food cooking support member within the interior compartment;
• an upper heating source operatively supported within the interior compartment by the oven body above the food cooking support member;
• a radiant lower heating source operatively supported within the interior compartment by the oven body and positioned below the food cooking support;
• a heat transfer device operatively supported within the interior compartment that is spaced below the food cooking support member and that is spaced above the lower heating source, wherein the heat transfer device comprises;
• a heatable tray that transfers radiant heat from the lower heating source to food supported by the food cooking support member;
• and
• a control system configured for operating the upper and lower heating sources in accordance with a selected cooking mode from a plurality of selectable modes, the control system comprising a processor and memory with operating parameters for each of the plurality of selectable modes, wherein at least one selectable mode includes a set of operating parameters within memory that are executable by the processor, the operating parameters determined at least in part by the absorptivity of radiant energy from the lower heating source by the heatable tray and the emissivity of the heatable tray of radiant energy from the heatable tray toward the food cooking support member, wherein the operating parameters control the lower heating source for heating the heatable tray by radiant energy so that the heatable tray can further transfer radiant energy to food supported by the food cooking support member.
