  • the extractor hood according to the invention is characterized in that the frame comprises one or more depressions which extend in such a way into the internal volume, the filter is movable from the mounting position to a tilted position by force of force on the filter directed into the internal volume. In the tilted position, the filter is tilted with respect to the opening. At the same time it is held in this position by means of magnetic force on the one or more wells.
  • a tilted position is meant a position in which the filter is rotated relative to the plane in which the opening formed in the frame lies.
  • the depressions provided in the extractor hood according to the invention are preferably arranged on an edge, by means of which the opening in the frame is delimited.
  • the extractor hood according to the invention allows easy removal of the filter by a user exerts a compressive force in the interior volume of the hood inside.
  • the magnetic attachment ensures that the filter does not fall down unintentionally during removal.
  • the attachment of the filter according to the invention makes it possible to dispense with handle elements on the filter. Accordingly, in a preferred variant of the invention on an outer side of the filter, which points away from the inner volume, no handle elements attached. In other words, the outside of the filter is a substantially continuous surface. By omitting the handles costs can be saved. Furthermore, the filter area can be increased if necessary, whereby the performance of the extractor hood is improved.
  • a respective depression in the context of the extractor hood comprises an oblique section which extends at an oblique angle with respect to an inner side of the filter, which allocates to the inner volume, into the inner volume.
  • An oblique angle is understood to mean an angle of less than 90 °. Preferably, the oblique angle is 45 ° or less.
  • the filter is held in the tilted position at the oblique portion by magnetic force.
  • the opening in the context of the extractor hood is limited by a rectangular edge, wherein the filter in plan view preferably also has a rectangular shape.
  • the filter in plan view preferably also has a rectangular shape.
  • this embodiment is at two opposite edges of the rectangular edge of the opening and optionally only at these two opposite edges each one recess provided, wherein the two recesses are arranged at the same longitudinal position along the two opposite edges.
  • the two recesses are arranged in a preferred variant of the embodiment just described in the longitudinal direction of the respective edges offset from the center thereof. A particularly small application of force is achieved in this case by arranging the two recesses at one end of the respective edges. Furthermore, the two recesses preferably have substantially the same shape.
  • only a single recess is provided on two opposite edges of the rectangular edge of the opening and possibly only on two opposite edges, which extends between the two opposite edges.
  • the magnetic force is generated by one or more magnets and in particular permanent magnets which are arranged on the filter and / or on the frame.
  • the magnet or magnets may be provided exclusively on the frame, in which case the filter comprises metallic material (in particular iron), which is attracted by the magnet (s).
  • the magnet or magnets may be provided exclusively on the filter, in which case the frame comprises metallic material which is attracted by the magnet (s).
  • the distribution of the magnets preferably takes place in such a way that a plurality of magnets are provided at each of the two opposite edges of the rectangular edge.
  • one or more magnets of the plurality of magnets are arranged in the respective recess, whereas one or more magnets of the plurality of magnets are arranged outside the respective recess.
  • a single magnet is positioned in the respective recess, whereas two magnets are located outside the recess. This limits the number of magnets to a total of six magnets (three magnets per edge).
  • Fig. 1 and Fig. 2 show views which illustrate the attachment of a filter in an embodiment of the hood according to the invention.
  • the view of Fig. 1 makes a section along the dash-dotted line L from the top view of Fig. 2
  • the filter 1 is arranged in a frame 2 of the hood above a hob and covers an opening 3, which has a rectangular edge 4 and is formed in the frame 2.
  • fumes is sucked through the opening, which is filtered by the filter 1. Above all, the filter removes grease from the vapor.
  • the contour of the filter is in the plan view of Fig. 2 indicated by a dashed line.
  • the filter comprises filter mats in a manner known per se, which are surrounded by an outer profile frame. The profile frame and the filter mats are not shown separately in the figures.
  • the filter 1 covers an internal volume VO inside the hood with an outside 101 of the filter is directed to the hob, whereas the inside 102 of the filter is turned to the internal volume VO.
  • the filter 1 is designed handle-less on its outer side 101, ie its outer side forms a substantially flat surface. This surface is flush with the frame 2, which thereby is achieved, that the filter is positioned in a recess 10 in the frame, wherein the depth of the recess corresponds to the thickness of the filter.
  • the four edges of the opening edge 4 are in Fig. 2 designated by the reference numerals 401, 402, 403 and 404.
  • Magnets 901, 902 and 903 are respectively arranged on the frame 2 at the two edges 402 and 404. These magnets are permanent magnets.
  • fastening position of the filter 1 via the magnets 902 and 903 is held on the frame 2.
  • the profile frame of the filter comprises a metallic material, which is attracted by the magnetic force of the magnets 902 and 903.
  • a recess 5 is formed in the frame in each case.
  • the cross section of the depression is off Fig. 1 seen.
  • the recess 5 comprises a portion 6 which extends from a lower edge 8 of the frame 2 at an oblique angle upwards and ends at an upper edge 8 '.
  • the section 6 is followed by a vertically extending portion 7, which extends downwards and ends at the level of the outside 101 of the filter. From there extends a vertical section of the frame 2.
  • the magnet 901 is positioned on the section 6. It is thus spaced from it in the attachment position of the filter, so that it exerts substantially no attraction force on the filter.
  • the strength of the magnets 902 and 903 is designed so that even these magnets are sufficient to keep the filter 1 on the frame 2.
  • a person pushes in an area between the two opposite recesses 5 on the outside 101 of the filter. This is in Fig. 1 indicated by an arrow P1.
  • the magnetic force of the magnets 902 and 903 is overcome so that the filter tilts along the two edges 8 of the opposing recesses 5, as in FIG Fig. 3 is shown.
  • the left end of the filter comes into contact with the respective sections 6 of the opposing recesses 5.
  • the magnetically attractive force of the magnet 901 then holds the filter in the tilted position so that it does not drop unintentionally when it is removed.
  • the filter can then be easily withdrawn by a tensile force in the direction along the section 6 against the magnetic force of the magnet 901.
  • Fig. 3 clarified, wherein the direction of force for withdrawing the filter is indicated by the arrow P2.
  • the removal of the filter is achieved by appropriate recesses in the context of the hood that a filter can be removed by a pressure on its outside of the cooker hood. It can thus be dispensed with handles on the filter, whereby the cost of manufacturing the filter can be reduced.
  • the filter surface can be increased due to the omission of the handles, resulting in a better performance of the hood in terms of displacement and Fettabscheidegrad.
  • an appealing handle-less design is achieved and ensures a haptic comfortable removal of the filter.
  • two recesses 5 are respectively provided at opposite edges of the frame opening.
  • only a single depression can be provided, which extends continuously across the opening 3 from the edge 402 to the edge 404 of the opening edge.
  • the inclined portion 6 extends between two opposite sides of the opening.
  • even more magnets may be provided in the region of the section above the opening.
  • holes can also be formed in this section in order to counteract a reduction in the power of the extractor hood.
  • corresponding recesses may be provided in addition to or as an alternative to those described in US Pat Fig. 2 Wells shown - may also be formed in struts that extend across the opening 3 away between the opposite edges 401 and 403 of the opening edge 4.
