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.

Abstract: A thermal sensor, in particular for a chemical reactor comprises an enamelled cylindrical shell having at its inner end a thin base and an inner sleeve welded to the base of the shell. A temperature measuring head comprising at least one thermal sensing element in a compression resistant insulating mass of low thermal inertia in a casing is pressed against the base of the shell by a compression spring acting between the temperature measuring head and a connector coupled to the inner sleeve of the shell by a bayonet point. Lead wires from the temperature measuring head extend out through a tubular stem having at its inner end a socket connected with the connector by a second bayonet joint. A guide sleeve has an inner end surrounding the inner sleeve of the shell and a reduced diameter outer end receiving the tubular stem. The bayonet joints provide for easy removal and replacement of the temperature measuring head.
