Extractor hood with a flue casing and a first pivotable moisture screen attached to the flue casing

摘要

A crank mechanism (12) automatically moves a vapor-collecting canopy (4) between two end positions. The crank mechanism includes a crank disk (14) and an electric motor (16) which rotates the crank disk. The crank disk is connected by a push rod (18) to the vapor-collecting canopy to allow transmission of torque from the crank disk to the canopy.
