ABSTRACT:
A baking oven has a housing formed by a back wall and by circumscribing walls. It is divided into an air heating -and- propelling room and a baking compartment by a vertical wall parallel to the back wall. The rear wall has a central air suction opening for an air fan located in the aforesaid room, the latter further containing heating coils for heating the air propelled by the fan. The rear wall edges terminate short of the housing circumscribing walls so as to define a peripheral air outlet passage; the fan thus creating an annulus-like hot air current in the baking compartment, between the air outlet passage and the suction opening for baking dough products in the baking compartment. An air diffusing ring is provided in the aforesaid room about the fan; the ring being a perforated band of which the width is about equal to the distance between the back and rear walls. Air guiding flanges are formed along the edges of the vertical rear wall, being turned toward the baking compartment.
