Abstract

Systems and methods for an oven include a housing, a heating chamber positioned within the housing, at least one oven door to provide access to the heating chamber, an external nesting rack positionable on or near the housing, and a movable cook surface, the movable cook surface movable between a position within the heating chamber and a position at least partially external to the heating chamber, such that when the movable cook surface is in the position at least partially external to the heating chamber, the movable cook surface is positioned at least partially recessed below a top surface of the external nesting rack. One or more heat packs can be included to provide variable forms of heat to the heating chamber.

Dependent claims

An oven comprising:

a housing;
a heating chamber positioned within the housing;
at least one oven door to provide access to the heating chamber;
a cavity within the housing for distribution to an upper air plenum and a lower air plenum to provide an air convection;
a cook surface positioned in the heating chamber, the cook surface to support an item for heating within the heating chamber;
an upper heat pack positioned between the upper air plenum and the cook surface to direct infrared heat downward into the heating chamber;
a lower heat pack positioned between the lower air plenum and the cook surface to direct infrared heat upward into the heating chamber;
the upper heat pack including a plurality of upper heat units supported by an upper frame and being generally parallel to each other with a predetermined space between each upper heat unit, each upper heat unit including an upper heat unit trough, the upper heat unit trough including an open gap between at least an upper heat unit trough first side wall and an upper heat unit trough second side wall, the upper heat unit trough forming a protective housing for at least one upper heat unit resistive heating element positioned within the upper heat unit trough and supported by an upper heat unit heating element support structure, and an upper heat unit cover positioned on the open gap, the upper heat unit cover including a series of perforations;
the lower heat pack including a plurality of lower heat units supported by a lower frame and being generally parallel to each other with a predetermined space between each lower heat unit, each lower heat unit including a lower heat unit trough, the lower heat unit trough including an open gap between at least a lower heat unit trough first side wall and a lower heat unit trough second side wall, the lower heat unit trough forming a protective housing for at least one lower heat unit resistive heating element positioned within the lower heat unit trough and supported by a lower heat unit heating element support structure, and a lower heat unit cover positioned on the open gap, the lower heat unit cover including a series of perforations;
wherein the air passes out of the upper air plenum and into the predetermined space between each upper heat unit and then into the heating chamber such that a flow path of the air convection is directed to avoid contact with the upper heat unit resistive heating element positioned within the upper heat unit trough;
and
wherein the air passes out of the lower air plenum and into the predetermined space between each lower heat unit and then into the heating chamber such that the flow path of the air convection is directed to avoid contact with the lower heat unit resistive heating element positioned within the lower heat unit trough.
