From there, the air exits through the air outlet opening 126 from the filter unit 12 and passes through the air inlet opening 115 of the blower housing 113 in the blower housing 113 where it is blown through an air outlet opening (not shown) of the blower housing 113. From there, the air passes either indirectly via an outlet channel (not shown) or directly to an air outlet 18 (s. FIG. 1 From there, the air can be discharged into the environment or into the room in which the combination device 1 is operated.
  • Liquids, such as water and grease, deposited from the air at the filter elements 120 (1200, 1203) may, for example, run down the inside of the outer wall 1212 of the filter support 121 and be collected in the collection area 122 and not enter the blower 110th
  • liquid which runs in through the air inlet opening 125 into the filter unit 12, via the slots of the upper profile set 1201 of the upper filter element 1200 in the upwardly facing profiles of the lower profile set 1202, which form the collecting element 127, and caught there. If a large amount of liquid enters the filter unit 12, for example during overcooking of food, first the collecting element 127 and then the collecting area 122 of the filter unit 12 fills. In the filter unit 12, in particular in the outer wall of the filter holder 121, overflow openings 123 are introduced , Over this, the liquid flows into the overflow container 13 provided around the filter unit 12.
  • FIG. 4 a further embodiment of the filter unit 12 according to the invention is shown.
  • the lower profile set 1202 of the upper filter unit is inclined from the horizontal.
  • the lower filter element 1203 is arranged inclined in this embodiment from the horizontal.
  • the lowest point of the filter elements 120 is formed on the right side of the lower profile set 1202, which serves as a catch element 127, and on the right side of the lower filter element 1203. Via this lowest point, liquids can flow down from the collecting element 127 and the lower filter element 1203 on the inside of the outer wall of the filter holder 121.
  • FIG. 5 a further embodiment of the filter unit 12 according to the invention is shown.
  • the lower profile set 1202 of the upper filter unit 1200 has a bent or angled shape.
  • the lower filter element 1203 has a bent or angled shape in this embodiment.
  • deepest points of the filter elements 120 are respectively formed on the right and the left side of the lower profile set 1202, which serves as a collecting element 127, and on the right and left side of the lower filter element 1203. Via these lowest points, liquids can flow down from the collecting element 127 and the lower filter element 1203 on the inside of the outer wall of the filter holder 121.
  • the fan of the extractor device can be located directly below the recess in the hob.
  • the recess may be rectangular or round.
  • the filter unit with the filter elements which may also be referred to as a grease filter, is preferably removable from the combination device.
  • a labyrinth of U-profiles is formed in the upper filter element through which the sucked air can flow.
  • Grease or water can be collected in the lower U-profiles and from there into a collection area of the filter unit.
  • an overflow container can be provided into which liquid can flow out of the collecting area.
  • the overflow container is preferably fixedly mounted in the combination device and is therefore also referred to as a static container.
  • the static container can not be removed preferably, but can be cleaned by hand or emptied from below, through an opening.
  • the present invention has a number of advantages.
  • the filter unit according to the invention possible positioning of the fan under the recess and the orientation of the air inlet opening upwards, possibly only one fan is required.
  • This fan can be larger, rotate slower and thus produce less noise.
  • the blower can be protected by the filter unit and optionally an overflow container.
