  • the Abscheidebleche 41, 41 ', 41 ", 43, 43', 43" each formed as perforated plates. Through the openings of the perforated plates, only a small part of the exhaust air flow is forced, which is nevertheless sufficient to prevent the buildup of a laminar flow at the respective, the Ab povertyansaughunt facing perforated plate backside and instead to force further turbulence in the exhaust air flow and conglomeration of small, in the exhaust air stream still entrained fat particles.
  • the area ratio (not shown) of the respective perforated plates from open to closed regions is greater than 50%. In this way, sufficient areas are available for the separation of fat particles still contained in the exhaust air. Even with an area ratio of less than 55%, the perforated sheets still have a sufficient stability for merely attaching them to the second opposing side wall surfaces 48, 50 of the air conveying duct 10.
  • the holes (not shown) of the perforated plates each have a diameter between 1 and 5 mm.

How through FIG.
  • the inclination of the fins 84 is determined by an inclination angle ⁇ , which in turn is defined by a tangent plane E T of the outer surface of the fin 84 adjacent to the plane E L of the air conveying passage 10 and the plane E L of the air conveying passage 10, wherein the tangential plane E T includes a line in which the planes E O and E T intersect.

  • the lamellas 84 of the abovementioned lamellar grid 82 which can be inserted into the inlet opening 12 of the air-conveying duct 10 and which are arranged at a particular angle of inclination.
  • the louver grid is detachably connected to the two second opposite side wall surfaces of the air delivery channel 10.
  • the slidable closing device 86 is arranged directly above the lamellar grid 82, which thus carries the closing device in the sense of a slidable slide.

  • the closing device 86 can be moved in such a way that it releases the inlet opening 12 either for one of the two conveyor channel halves 14, 16 or only one half of both conveyor channel halves 14, 16.
  • the extractor hood according to the invention can be optimally adapted to the conditions prevailing on a hob be adapted, ie depending on whether the hob is operated with only individual cooking zones or even all cooking zones.
  • the slidable closing device 86 is achieved in an advantageous manner that the sucked into the air conveyor duct 10 exhaust air volume is always consistent.
  • FIGS. 6a, 6b and 7a, 7b each illustrate the inventively enforced, twice successive redirection of the exhaust air in the second and third air ducts

  • the FIGS. 7a and 7b the air conveyor duct 10 according to the second preferred embodiment of the extractor hood according to the invention.
  • FIG. 6a shows the slidable closure 86 in one of the three possible positions, namely, in which the inlet opening 12 to one half of the two conveyor channel halves 14, 16 is released.
  • the second 34, 36 and third air guide means 38, 40 each two successive redirecting the exhaust air flow, which has a corresponding turbulence of the exhaust air flow in these areas.
  • small particles of fat entrained in the exhaust air flow conglomerate. Due to their mass, the conglomerated fat particles can no longer follow the flow lines of the diverted exhaust air flow, but adhere to the second 34, 36 and third air guide means 38, 40.
  • the fine separation devices 42, 42 'disposed downstream of the third fine separation devices 34, 36 are thus supplied with a highly pre-cleaned exhaust air flow.
  • FIG. 6b shows the closing device 86 in one of the other two positions, namely in a position in which the inlet opening 12 is released to a delivery channel half.
  • the second 34, 36 and third air guide means 38, 40 each two successive redirecting the exhaust air flow, which has a corresponding turbulence of the exhaust air flow in these areas.
  • Figure 7a shows the slidable closure 86 in the position in which the inlet opening 12 of the air conveyor channel 10 is released to one half of the two conveyor channel halves 14, 16 respectively.
  • each delivery channel half 14, 16 there is a prominently forced double successive deflection of the exhaust air flow in the region of the second air guiding device 34 or 34 'and in the region of the third air guiding device 38 or 38'. Furthermore, although not quite as significant, a forced, two-fold successive deflection takes place also in the region of the second air guiding device 36 or 36 'and in the region of the third air guiding device 40 or 40'. Due to the associated with the deflection swirling of the exhaust air flow, there is a conglomeration of small, entrained in the exhaust air flow fat particles, and for the reasons explained above to a separation of the conglomerated fat particles in the aforementioned air guiding devices.
  • FIG. 7b shows the slidable closure device 86 in a position in which the inlet opening 12 is released to one of the two conveyor channel halves 14, 16.
  • each conveyor channel half 14, 16 communicates each conveyor channel half 14, 16 via the respective lower portion 18, 20 of the respective side wall surface of the two opposite second side wall surfaces 44, 46 with the respective associated Abluftansaughunt 22, 24, which communicates with the respective fan chamber 26, 28, in the in each case a radial fan is arranged.
