Abstract: The invention relates to a vapour extraction device for extracting cooking vapours downward. The vapour extraction device comprises a fan apparatus for sucking in the cooking vapours having a fan impeller which can be driven in rotation, a fan motor for supplying a drive torque, and a releasable fan coupling for transmitting the drive torque to the fan impeller.

Abstract: A fume extraction device for the downward extraction of cooking fumes comprises at least one inflow opening for the inflow of the cooking fumes, and at least one fan for suctioning the cooking fumes at the at least one inflow opening, such fan having a fan propeller that is mounted so as to be rotatable about a rotation axis, wherein the rotation axis is oriented so as to be inclined in relation to a horizontal plane and to a vertical direction.

Abstract: In a hob system having at least one induction hob and an extractor apparatus, a control device for the control of the extractor apparatus is arranged in an induction generator housing.

Abstract: A wall box for a ventilation system comprises a housing delimiting an interior, in which a through-flow region is defined. In the interior is arranged at least one flap arrangement having a flap arranged on a suspension mounting. For an area A of a cross section of the interior perpendicular to a flow direction, A/K>2/?r, wherein K indicates an area of an enveloping circle with smallest possible radius, which circle completely conceals the cross section of the interior. The flap of the at least one flap arrangement has at least in an open position a flap contour which in regions adjacent to a pivot axis is adapted to a cross-sectional contour of the interior in the respective region adjacent to the pivot axis.
