ABSTRACT:
An air curtain door system for inhibiting heat and exhaust exiting from an access opening of an oven includes a door panel which has an access opening and a mantle attached to a bottom end of the access opening, the mantle having an air outlet slot extending horizontally along the access opening; an air inlet opening near a lower end of the door panel; a hollow chamber within the door panel disposed from the mantle to near the lower end of the door panel; an air supply means for providing air supply to the hollow chamber through the air inlet opening; and an exhaust venting assembly adjacent to an upper end of the door panel, for pulling air exiting from the air outlet slot into the exhaust venting assembly, thereby forming an air curtain covering the access opening at the interior side of the door panel.
