  • the mounting of the screen elements is fixed.
  • the at least one fastening element is firmly attached to the extractor device and in particular firmly to the suction shaft.
  • a number of advantages can be achieved by using at least two flat screen elements according to the invention, the suction gap being formed between the screen elements, the screen elements protruding upwards over the passage openings of the suction shaft and the at least two screen elements being detachably and fixedly mounted in the suction shaft.
  • the areas of the screen elements that protrude beyond the passage openings of the suction chute form the air guidance of the air from the suction gap to the suction chute, in particular to the air inlet opening. Since the screen elements are also mounted detachably in the suction shaft, they can be easily removed from the fume extraction device. When removed, the screen elements can be cleaned in a dishwasher, for example. When extracting fumes and vapors, impurities will be deposited on the screen elements.
  • the screen elements can be removed from the vapor extraction device without tools and cleaned, they can act as filters, i.e. be used to separate contaminants.
  • the screen elements are particularly preferably held at least partially in the suction shaft and in particular on the fastening element by their own weight. In particular in the case of screen elements made of glass, the high inherent weight can ensure a secure hold, for example in a rail.
  • the construction of the vapor extraction device is simplified by the disc elements being held fixed in the vapor extraction device. In particular, no movement devices such as drives and motors are necessary. Also reduce the size of the vapor extraction device and thus the space required for it.

If two front screen elements are provided, their width is preferably chosen such that the sum of the widths and the distance between the front screen elements is less than the width of the rear screen element.
  • the suction gap is increased in its height direction.
  • the suction gap in this embodiment is inclined from the horizontal and extends from the edges of the smaller screen element or elements to the edges of the larger screen element.
  • this embodiment also allows air to be drawn in laterally, ie via the distances between the outer side edges of the front screen element or elements and the side edges of the rear screen element.
  • the upper edges of the at least two screen elements are at different heights above the passage openings of the suction shaft.
  • the screen element, the upper edge of which is at a lower level preferably faces the hob and the screen element, the upper edge of which is at a higher level, is located behind this screen element. This ensures that vapors are sucked in reliably.
  • the size of the suction gap formed between the upper edges of the screen elements is larger than in the case of screen elements whose upper edges are at the same height.
  • the suction gap is in this case inclined from the horizontal and has a larger size with the same distance between the screen elements.
  • the suction is also supported in this embodiment in that vapors can be prevented from brushing past the rear screen element due to its greater height above the air inlet opening.
  • the front screen element which faces the hob, can be in such a position in the extractor device according to the invention that its upper edge is at a height that corresponds to the height of a cooking vessel on the hob.
  • the suction gap of the fume extractor device is therefore close to the top edge of the cooking vessel and reliable suction can thus be guaranteed.
  • the raised rear screen element can also be used to create a splash guard for a room wall that can be located behind the extractor hood.
  • the upper edges of the at least two screen elements can be at the same height.
  • the upper edge of the at least two screen elements can be at the same height above the passage openings.
  • This embodiment is particularly preferred when the fume extraction device is arranged between adjacent hobs, since fumes and vapors can be reliably sucked in from both hobs.
  • This embodiment is also advantageous in the case of an extractor device integrated centrally in a cooktop, since vapors and vapors can be reliably sucked in from the cooking zones of the cooktop adjacent to the extractor device.
  • the suction gap preferably runs at least along the upper edge of at least one of the screen elements and along the side edges of the at least one screen element.
  • the suction gap also extends along the distance between the two front screen elements. In this way, on the one hand, reliable suction can be ensured due to the great length of the suction gap.
  • a flow can be generated by the lateral and/or central suction, by which the vapor is deflected and the suction is thus further improved.
  • the extractor device can have two screen elements that form the vapor trap.
  • the invention is therefore described in the following primarily on the basis of an extractor device with two screen elements.
  • the fume extraction device has three screen elements.
  • the screen elements are arranged in such a way that two are laterally adjacent to one another and offset horizontally with respect to the third screen element. If a cover plate is provided at the upper end of the suction shaft, a through-opening for a rear screen element and a separate through-opening or a common through-opening are preferably provided in this cover plate for each front screen element.
  • directions such as front or rear refer to an extractor hood that is installed in or on a hob.
  • the front is the direction that faces the hob or a cooking zone
  • the rear is the direction that faces away from the hob or a cooking zone.
  • the two laterally adjacent screen elements are preferably the front screen elements and the third screen element represents the rear screen element.
  • the two laterally adjacent screen elements are in front of the air inlet opening of the vapor extraction device and the rear screen element is behind the air inlet opening.
  • Laterally adjacent screen elements are those in which a side edge of one screen element faces a side edge of a further screen element and the two screen elements lie in a common plane.
  • the third screen element preferably lies in a plane which is offset to the rear from the plane of the first two screen elements.
  • the suction gap is thus at least determined by the distance between the upper edges of the front screen elements and the upper edge of the rear screen element and by the distance formed between the front screen elements.
  • another part of the intake gap can also be formed between the side edges of the front screen elements, which face away from the other front screen element in each case, and the side edges of the rear screen element.
  • the horizontally offset third screen element preferably has a larger area than the two laterally offset screen elements.
  • the horizontally offset screen element is preferably the rear screen element and the two adjacent screen elements are the front screen elements.
  • each of the screen elements is received in a fastening element, which is preferably a rail.
  • the fastening element is fixed in the suction shaft. Because the screen element is releasably attached to a fixing element that is fixedly mounted, only the screen element itself is separated from the vapor extraction device when the screen element is removed.
  • the fastening element on the other hand, can remain in the vapor extraction device. If the fastening element is a rail, then the flat screen element, which is preferably a disc, can be easily pushed into the rail from above and pulled out of the rail for removal. If the rail represents a horizontally running rail, the screen element can be held by the rail at least along the entire lower edge and preferably the lower area of the side surfaces. If the rail is a vertical rail, it is preferably closed at its lower end. The lateral area of the lower edge of the screen element and the lower area of the side edge of the screen element are therefore held on this rail.
  • the screen elements are made of glass.
  • This embodiment is advantageous because the screen elements have a high intrinsic weight.
  • the screen element can be reliably held in a fastening element, in particular a rail, by its own weight.
  • This further simplifies the structure of the fume extraction device, since the fastening element can be designed in a particularly simple manner and does not have to have any further elements, such as clamping or locking elements.
  • a screen element made of glass can be cleaned in a simple manner.
  • the suction shaft of the fume extraction device has a depth of less than 120 mm, preferably 90 mm.
  • the depth is understood to be the dimension of the suction shaft that lies in the direction between the edges on which the screen elements are arranged.
  • the dimension in the direction perpendicular to the surfaces of the screen elements is understood as the depth of the suction shaft.
  • Such a small depth can be achieved with the vapor extraction device according to the invention, since the vapor extraction device has a particularly simple structure. In particular, drives or motors and guide elements that would be necessary for moving the screen elements are not required according to the invention. Due to the small depth, the extractor device can also be installed, for example, behind a hob that is integrated in the work surface of a row of walls.
  • the fume extraction device comprises at least one lighting device.
  • the lighting device can be provided, for example, on the upper edge or lower edge of at least one of the screen elements and can consist, for example, of light-emitting diodes. If the material of the screen elements is transparent, the light can be coupled into the screen element by an illumination device arranged on the lower edge and the entire screen element can emit the light and thus form a planar illumination.
  • This embodiment can be used particularly advantageously in the fume extraction device according to the invention, since the screen elements project upwards over the passage openings and can therefore function as lighting or design elements.
  • the light can also be emitted only via the edges and thus serve as a functional light.
  • the screen element or elements also serve as a light guide.
  • the invention relates to a kitchen appliance with at least one hob and an extractor device according to the invention.

  • the glass or other plate material can also serve as a splash guard and as an optical waveguide.
  • Light can be coupled in from below over the edge. Appropriate edge processing helps with the decoupling and direction of the light beam.
  • the present invention has a number of advantages. On the one hand, no mechanical device, for example no moving device and no drive, is no longer required, which one would like to hide. In the embodiment in which the extractor device has two front screen elements, air is also sucked in horizontally in the middle. Due to the omission of a motor movement, a slimmer (less deep) downdraft extractor can be produced with the extractor device according to the invention. The depth of the extractor device can be less than 120mm and can be reduced to 90mm, for example, because there are no motors and flaps. Thus, the extractor according to the invention is also easier to install in the work surface. In addition, since the screen elements are detachably fastened and can therefore be removed without tools, the fat label can be improved since the contaminants deposited on the screen elements are calculated together with the contaminants on filters.
