  • An extractor hood is described in which a fan is provided in the extractor device. Air is transported via the fan to the fan via an intake area, from where it is discharged radially and directed to a filter element which radially surrounds the fan. This filter element is designed as a grease filter. After cleaning through the filter, the cleaned air is discharged via outlet openings on the upper front of the extractor into the room from which the air was sucked.
  • a disadvantage of this type of extractor hood is that the fan is contaminated by the air entering the fume extractor.
  • the grease filter is aligned vertically and so the fat deposited therein runs down in this and must be collected.

  • the extractor device is, in particular, an extractor hood which is used for extracting and cleaning fumes and vapors via a hotplate or another workstation.
  • a fan which is also referred to below as a fan

  • the odor filter according to the present invention is a filter element which at least partially surrounds the fan.
  • surrounding the fan is understood as meaning an arrangement of the odor filter which at least partially covers the blow-out opening of the fan.
  • the blow-out opening of the fan is formed by the blades arranged over the circumference of the fan wheel or by the clearance existing between the blades.
  • the odor filter element completely surrounds the circumference of the fan wheel.
  • the filter element may in this case be arranged at a distance from the blow-out opening of the fan.
  • the quality of the air discharged through the extractor is high, and the load on the components of the extractor is in particular of the fan due to contamination, minimized by the grease filter.

  • a maximum filter surface of the odor filter is provided, whereby the air quality of the extractor device leaving the air is increased.
  • the flow resistance to which the air discharged from the fan is exposed is minimized. This is advantageous over extractor devices in which the air flow emitted by the fan is directed into a fume hood housing and from there can escape from the housing only through a small area in which the outlet opening is provided.
  • the odor filter is arranged in the discharge direction of the fan.
  • the blow-out direction of the fan is preferably perpendicular to the suction direction of the fan.
  • the supply line to the odor filter is also certainly possible in the extractor device according to the invention, since the fan power, which is necessary for the transport of air through the odor filter can be provided without problems even after a long time, since contamination of the fan by grease due to the upstream Grease filter is prevented.

  • the odor filter has a thickness in the range of 15mm to 25mm, preferably 20mm.
  • a thickness of the odor filter can be realized without having to accept any losses with regard to the air quality output by the extractor device or having to make increased demands on the delivery rate of the fan. This is because the area over which the odor filter is flowed is maximized. Despite the relatively large thickness of the odor filter, therefore, a backflow of the air to be passed through the filter is not to be feared.
  • the grease filter which is connected upstream of the fan, has at least two mutually angled filter surfaces.
  • the extractor device which does not flow in the vertical direction of the inlet opening of the fan.

  • high-performance fans that is radial fans with backward-curved blades, are operated at higher speeds, and the efficiency achievable with these radial fans is better in comparison with drum fans. This higher efficiency is advantageously used in the extractor device according to the invention, since the pressure difference is determined by the odor filter arranged around the fan is increased. When using a radial fan with backward curved blades, this pressure difference is not a problem.

  • the air inlet in particular the air inlet pipe, can be aligned with this main flow direction so that the air inlet is perpendicular to the main flow direction.
  • a double-flow fan would be to allow the suction on both air inlets the orientation of the Air inlets parallel to the main flow direction and would therefore require increased fan power to allow suction of the vapors and fumes in the air inlets can.
  • the extractor device has an inner frame for holding the fan.
  • the inner frame is preferably arranged between the fan and the odor filter.
  • the inner frame is a frame that does not or only slightly affects the air outlet of the fan.

This is particularly important if the extractor device is a circulating air unit, that is to say a pure recirculation unit. It has been shown that the largest possible through-flow surface of the odor filter or activated carbon filter is required. The ratio of the thickness of the filter and the surface that is streamlined is also important for the delivery volume.
