1. An oven, comprising:
- an outer envelope, an inner muffle and a door, together defining an inner cooking compartment and oven wall cooling air passageway between the outer envelope and the muffle;
a passage extending through the muffle;
an air pump for passing a stream of environment air through the cooling air passageway and past the muffle passage;
a profile depression baffle having the crosssectional shape in the cooling air flow direction of an airplane wing with a curved upstream portion and a longer ramp-shaped downstream escape portion, said baffle having an opening between said curved upstream portion and said ramp downstream portion, said profiled depression baffle being means for producing a suction at said opening for drawing cooking and cleaning gases from said compartment, through said opening and into the cooling air stream; and
a catalytic reactor in said muffle passage.

Abstract
An electric domestic oven includes an air exhaust channel above the exit from a catalytic reactor. A depression baffle is located in the air exhaust channel to provide a suction orifice in the area of the catalyser unit to draw cooling and cleaning gases from the cooking compartment. The depression baffle has a curved upstream portion and a ramp-shaped downstream portion. A deflector may be placed above the baffle in the channel.
