Abstract
An efficient, low cost, gas-fired convection oven is disclosed. The oven includes a burner, such as a ceramic induced draft/boosted burner with premixed pressurized air/fuel gas supply, which fires combustion products through an opening in a baffle directly into a convection blower. The blower assembly, protected by a shield/deflector structure, also draws gases from a cooking chamber around the burner to mix with combustion products in a blower chamber. Action of the blower directs the mixture through the blower to circulate through gaps formed by the top and bottom of the baffle and into the cooking chamber. The oven avoids complex, costly wall-type heat exchangers, has no combustion chamber, and provides efficient, uniform cooking in a unit of low manufacturing cost.
