Cooking appliance with conductive heating capabilities
A cooking appliance includes an oven body having an interior compartment and a door panel for accessing the interior compartment, wherein the interior compartment is sized to receive a food product; a removable heated tray positionable within the interior compartment, wherein the heated tray includes a top tray surface and a first heating source positioned below the top tray surface; and a second heating source positioned within the interior compartment.
1. 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.
2. The oven of claim 1 , wherein the heatable tray comprises a relatively flat top surface.
3. The oven of claim 1 , wherein the heatable tray comprises raised rib features.
4. The oven of claim 1 , wherein the heatable tray comprises a plurality of grates.
5. The oven of claim 1 , wherein the heatable tray comprises a pattern of at least one of raised and depressed areas.
6. The oven of claim 1 , wherein the heatable tray further comprises at least one side wall extending from a top tray surface.
7. The oven of claim 1 , wherein the heatable tray is spaced from the bottom wall of the interior compartment.
8. The oven of claim 1 , wherein the radiant lower heating source comprises at least one heating element spaced from a bottom surface of the heatable tray.
9. The oven of claim 1 , wherein the heatable tray is removable.
10. The oven of claim 1 , wherein the heatable tray is adapted for use as an independent cooking device outside the oven.
11. The oven of claim 1 , wherein the heatable tray comprises an electrical connection for engagement with a receptor within the interior compartment.
12. The oven of claim 1 , wherein the upper heating source is positioned adjacent to the top wall.
13. The oven of claim 1 , further comprising a steam cleaning mode in which the heatable tray is further adapted to contain a quantity of liquid and convert at least a portion of the quantity of liquid into steam.
14. 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 within memory that are executable by the processor for each of the plurality of selectable modes, 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, wherein at least one selectable mode includes a steam clean mode that includes a set of operating parameters for controlling the lower heating source for heating the heatable tray having a quantity of water within the tray by radiant energy so that the heatable tray can generate steam within the interior compartment.
