ENHANCED AIR-FLOW CONVECTION OVEN

摘要

An enhanced, air-flow convection oven (1) is disclosed, comprising an oven chamber liner (20) circumscribed by a thermally insulated outer oven shell (10) with a heat source in a combustion chamber (30) between the shell (10) and the liner (20). Hot air flows from the combustion chamber (30) and into a uniquely constructed blower wheel assembly (60). The blower wheel assembly (60) has a concave central plate configuration which creates a negative pressure behind the blower wheel assembly (60), including a flow of hot air from the back of the blower wheel assembly (60) into the blower wheel assembly (60) as the wheel rotates. This hot air is mixed with air from within the chamber (30) to produce uniform heating throughout the chamber (30).
