Definitions

  • the present invention relates to a fume extractor, in particular a fume extractor in the form of a counter.
  • Meal are extractor devices that include a fan for suction of vapor and a Wrasencept. Above the Wrasentoxins, which is also referred to as a viewing hood, a channel is arranged at Essen, which is referred to as a fireplace. In the chimney usually the fan is included. In addition, the chimney directs the air drawn in by the fan to an air outlet of the extractor device.
  • Vapor extraction devices are used in two so-called modes.
  • devices are known that can be used in the exhaust air operation.
  • the air drawn in by the fan is released through an outlet to the environment after cleaning with filters or other cleaning agents.
  • the air sucked in and cleaned by the ventilator is discharged directly into the room in which the extractor device is operated.
  • the extractor devices work on the principle that the enriched with fat, moisture and cooking fumes air is first passed through a grease filter and then through the activated carbon filter.
  • This air duct with circulating air extractor devices is that the area over which the purified air can escape is low and therefore there are strong currents and noise developments.
  • Object of the present invention is therefore to provide a fume extraction device, with on the one hand a sufficiently large area for the discharge of purified air from the extractor device is present and still has a simple structure.
  • the object is therefore achieved by a fume extraction device with a viewing hood, a chimney disposed above the viewing hood and an air outlet unit, which forms part of the chimney.
  • the extractor device is characterized in that at least part of one of the walls of the air outlet unit consists of an air-permeable material and at least two walls of the air outlet unit constitute a one-piece component.
  • a vapor extraction hood for kitchens and particularly preferably a forage is referred to as the extractor hood.
  • the Esse can be configured as a Wandesse or Glassesse.
  • the viewing hood which is also referred to as Wrasenick, has a suction opening for sucking contaminated air.
  • a grease filter is preferably provided in the suction opening.
  • the chimney of the extractor device according to the invention serves on the one hand to accommodate the fan of the extractor device and on the other hand, the air duct of the air sucked through the fan and cleaned by the grease filter.
  • the air outlet unit is a component via which the air treated in the extractor device can escape from the extractor device.
  • the air outlet unit forms part of the fireplace.
  • the air outlet unit and the chimney can be formed by a common component. It is equally possible to carry out the air outlet unit as a separate component which is connected to the fireplace. In particular, at least part of the outer walls of the chimney is formed by the air outlet unit. As outer walls are in this context the Designates walls of the fireplace, which are visible to the user of the extractor device in the assembled state of the extractor device.
  • an air-permeable material of which at least a part of the walls of the air outlet unit, is understood in the context of this invention, a material having over its entire surface air outlet surfaces. In contrast to material in which openings or slots are distributed, a larger area for the air outlet can be made available with an air-permeable material. In the case of air-permeable material, most of the surface that covers it is permeable to air.
  • the individual openings or pores of the air-permeable material preferably have an opening cross section of less than 4 square millimeters, preferably less than 2 square millimeters.
  • At least two of the walls of the air outlet unit according to the present invention are a one-piece component.
  • all visible walls, that is, outer walls of the air outlet unit are combined as a one-piece component.
  • a component is referred to, which can be fixed with an assembly step on the extractor device.
  • fasteners may be provided which may be provided on the air outlet unit or may be present as a separate element.
  • the one-piece component comprising at least two of the walls of the air outlet unit may be manufactured as an integral component or pre-assembled. In the latter case, the at least two walls of the air outlet unit are preferably connected to each other inseparably. This can be done by known manufacturing methods, such as welding or riveting.

  • the air-permeable region of the air outlet unit is preferably larger than an area which may be covered by fastening or carrier elements.
  • the provision of air-permeable areas on at least three surfaces of the extractor device creates a large area over which air can escape from the air outlet unit.
  • this is of particular importance.
  • the entire sucked through the fan of the extractor fan air after cleaning must be delivered to the environment in the room in which the extractor device is operated. If this relatively large amount of air is emitted over a small area, in particular individual openings, for example in the form of slots, the flow rate of the exiting air is very high. There are thus tensile effects, which are unpleasant for the user of the extractor device.
  • the entire visible surface of the air outlet unit can serve for the air outlet.
  • a large area is thus made available and tensile effects can be avoided.
  • the occurrence of strong airborne noise that can occur at small openings and a small air outlet area is avoided.
