发明名称 Bakery oven with enhanced air flow
摘要 An air return system for a rotatable rack baking oven having a heat source and a blower associated therewith for providing a flow of heated air across a baking chamber of the oven. The outlet end of the blower is connected via ductwork to an air outlet vent which introduces the heated air into the baking chamber. The air outlet vent includes a lattice of fixed vanes which are elongated in the direction of intended air flow. This arrangement channels the heated air to exit normal to the outlet vent to maintain a well defined column of air with less turbulence. An air return vent is located opposite the air inlet vent and is operatively associated with the heating means and the inlet side of the blower. The air return vent includes a panel having a plurality of holes through which the air may be drawn. A number of return holes in the return vent are blocked such that their numbers vary in inverse proportion to the drawing force produced by the inlet of the blower. This produces a uniform draw of air from the baking chamber, aiding in the uniform flow across the chamber.
