  • the insulation 43a ensures reduced noise emissions and reduced heat input into a lower area of the kitchen base cabinet 42a.
  • the functioning of the hob system 1 according to this exemplary embodiment corresponds to the functioning of the hob systems 1 described above.
  • a further exemplary embodiment of a hob system 1 is shown.
  • an initial section 44 of the inflow channel 10 has a central longitudinal axis 45, which is oriented obliquely to a hob normal 46.
  • An angle between the central longitudinal axis 45 of the initial section 44 and the hob normal 46 is 45°.
  • the initial section 44 is circular in cross section.
  • the inflow opening 18 is elliptically shaped due to the oblique orientation of the central longitudinal axis 45 to the hob normal 46.
  • the total width B of the hob system is a maximum of 600 mm, in particular 560 mm, makes it possible for the first time to arrange the hob system 1 with the extractor device 3 in a kitchen base cabinet 42a with particularly small dimensions. This advantageously ensures that such hob systems 1 can be used particularly flexibly and can therefore be installed on a considerably larger scale.
  • a design of the hob system 1 with a maximum height of 200 mm is particularly advantageous, as this means that the storage space 42b is largely retained for holding kitchen utensils, for example.
  • the extractor device 3 includes two fans 19, each with fan wheels 25 rotatably mounted about an axis of rotation 20, the axes of rotation 20 each being oriented inclined to a horizontal plane and to a vertical direction.
  • the hob system 1 comprises four heating units 5, which are rectangular in plan view. The heating units 5 and the extractor device 3 are in signal connection with a user interface 9.
  • the extractor device 3 has an inflow opening 18 arranged centrally on a food carrier 4.
  • An initial section 44 of a vacuum channel section 17 is connected to the inflow opening 18.
  • the fans 19 each have a fan housing 43.
  • the fan housing 43 includes a vacuum connection opening 47.
  • the initial section 44 penetrates the vacuum connection opening 47.
  • a channel connection 48 connects the initial section 4 to the fan housing 43 in a fluid-tight manner.
  • connection standard 49 is oriented perpendicular to the vacuum connection opening 47.
  • the connection standard 49 includes a connection angle ⁇ of 80° with the axis of rotation 20.
  • Power electronics 50 for supplying the heating units 5 is mounted below the respective heating unit 5. Due to the inclination of the axis of rotation 20, an area for the power electronics 15, in particular, is created in an area between the respective heating unit 5 and the fan 19 Space required for particularly space-intensive individual components of the power electronics 15 is provided.
  • the two fans 19 overlap the heating units 5 both in a top view and in a side view.
  • the hob system 1 is therefore particularly compact.
  • a total height H is 180 mm.
  • a suction direction 51 of the fan 19 has a vertically upward directional component.
  • the suction direction 51 is oriented parallel to the axis of rotation 20. Because the suction direction 51 has the upward directional component, the fan 19 is reliably protected from penetrating liquids.
