Abstract
An enhanced, air-flow convection oven is disclosed, comprising an oven chamber liner circumscribed by a thermally insulated outer oven shell with a heat source in a combustion chamber between the shell and the liner. Hot air flows from the combustion chamber and into a uniquely constructed blower wheel assembly. The blower wheel assembly has a concave central plate configuration which creates a negative pressure behind the blower wheel assembly, inducing a flow of hot air from the back of the blower wheel assembly into the blower wheel assembly as the wheel rotates. This hot air is mixed with air from within the chamber to produce uniform heating throughout the chamber.
Claims19
An enhanced air flow convection oven comprising:
- an oven chamber enclosed by an oven chamber liner having a top, a bottom, two sides, a back with an air inlet opening therethrough effectively located between an upper and lower portion thereof, and an air outlet opening;
- a heat source located outside said oven chamber liner;
- a thermally insulated outer shell, circumscribing said oven chamber liner at a distance from said oven chamber liner forming a space between said oven chamber liner and the outer shell, said space formed along the sides, top, and upper and lower portions of the back of said oven chamber liner for allowing air to flow from said heat source, through said space and into the air inlet opening;
- a blower wheel assembly mounted for rotation within the oven chamber liner adjacent to said air inlet opening, said blower wheel assembly capable of mixing air from within the oven chamber liner with air from the air inlet opening within the blower wheel assembly;
- wherein air heated by the heat source moves along the sides, top and back of the oven chamber liner into the air inlet opening where it is mixed within the blower wheel assembly with air from within the oven chamber to provide for balanced heat.
