ABSTRACT:
A forced convection oven heated by burners in a combustion chamber beneath the oven. Hot gases pass via an outlet port into the restricted part of a pressure-reducing throat forming the central lower portion of a U-shaped passageway whose vertical limbs provide inlet and outlet manifolds to the oven cooking space. The shape of the throat ensures good mixing of these gases with gases circulated by a tangential or centrifugal type fan positioned upstream of the throat. The gas mixture from the inlet manifold enters the cooking space via a perforated side panel and travels across the oven and leaves through perforations in the side panel opposite and thence into the outlet manifold for re-circulation.
