  • Extractor hoods especially those used in kitchens, are known for filtering out liquid and solid contaminants as well as odors from the fumes and vapors produced during cooking.
  • Mechanical filters are usually used in the extractor hood for this purpose. Examples of mechanical filters used include expanded metal filters, perforated sheet filters, baffle filters (which can also be referred to as eddy current filters), edge extraction filters and porous foam media.
  • WO 2008/057262 A2 discloses a cooker hood with electrostatically supported air flow and filtration.

  • the plate-shaped separating and counter electrodes are connected to each other via electrically conductive webs and are arranged in such a way that the air entering the filter element first flows to the separating electrodes with wire-shaped ionization elements in between and then to the upwardly offset counter electrodes.
  • the separating electrodes are attached to the housing of the extractor hood via a partition wall.
  • a high-voltage device is provided in the housing of the extractor hood, which is connected to the electrodes of the electrodes of the filter unit.

  • the filter unit is also referred to as a filter module.
  • the filter unit is a portable filter unit that can be removed from the extractor hood and is preferably pre-assembled.
  • a filter unit that can be inserted into the extractor hood as a structural unit and removed from it as a unit is referred to as pre-assembled.
  • An extractor hood is an extractor device that can be, for example, an extractor hood or a ceiling fan.
  • the extractor hood preferably has an extraction gap According to the invention, the extraction gap is formed between an extractor housing and a baffle plate arranged offset from the extractor housing below the latter.
  • the extraction gap can also be referred to as an edge extraction gap.
  • the filter unit comprises an ionization unit, which can also be referred to as an ionization stage, and a separation unit, which can also be referred to as a separation stage.
  • the ionization stage preferably has at least one ionization element and at least one counter electrode.
  • the separation stage has at least one precipitation electrode and at least one counter electrode.
  • the separation stage is connected downstream of the ionization stage in the flow direction of the filter unit.

  • the separation stage preferably comprises at least one precipitation electrode and at least one counter electrode, which are plate-shaped and arranged alternately in the separation stage.
  • the filter unit comprises a housing.
  • the housing is preferably made of electrically non-conductive material. Both the ionization unit and the separation unit are accommodated in the housing.

  • the base and top wall of the housing as well as two side walls are formed by air-impermeable panels.
  • the front and back of the housing are open or formed by an air-permeable component, in particular a grille.

  • the housing has a top wall, a bottom wall and at least three side walls and one of the side walls is at least partially formed by a protective grille.
  • the bottom wall represents the underside of the filter unit and the top wall represents the top of the filter unit.
  • the bottom and the top wall are preferably horizontal when the filter unit is in the extractor hood. This can prevent the escape of contaminants separated in the filter unit.
  • the side of the housing of the filter unit which is at least partially formed by a protective grille, preferably represents the front of the filter unit. When the filter unit is in the extractor hood, the front of the filter unit is the side of the filter unit that faces outwards and through which air can enter the filter unit.
  • the side wall that forms the front of the filter unit can be completely formed by a protective grille.
  • a protective grille By forming the housing on this side by a side wall that consists at least partially of a grille, the entry of air and, on the other hand, access by the user of the filter unit and the extractor hood to the internal electrodes of the filter unit is prevented.
  • the provision of a protective grille increases the stability of the housing compared to a housing that is open at the front and thus makes the filter unit easier to handle. In particular, there is no risk of the housing becoming deformed when it is removed from the extractor hood and cleaned outside the extractor hood.
  • a drainage channel is formed on the housing.
  • the drainage channel is preferably formed on the rear of the housing, i.e. on the side opposite the side wall formed by the protective grille.
  • the drainage channel is particularly preferably formed by an extension of the base wall to the rear.
  • the drainage channel can have an incline that slopes downwards from the rear of the base wall of the housing of the filter unit.

  • precipitation electrodes and counter electrodes are arranged alternately in the separation unit and the precipitation electrodes and counter electrodes represent plates that extend parallel to the bottom of the housing of the filter unit.
  • the plates i.e. the precipitation electrodes and counter electrodes, are arranged alternately.
  • the electrodes are thus electrically charged alternately.
  • the positive precipitation electrodes are under positive electrical high voltage.
  • An electrical field is formed between the alternately arranged positive precipitation electrodes and negative counter electrodes during filter operation. This electrical field causes the solid and liquid substances already charged in the ionization unit to be deflected from the air stream by the electrical field and to the precipitation electrodes and Counter electrodes are precipitated or separated.
  • the separation unit has a simplified structure.
  • the filter unit preferably has a greater width than height. This allows the filter unit to be easily introduced into an extractor and in particular into a vertically running extraction gap.
  • the electrodes in the separation unit are arranged parallel to the bottom of the housing of the filter unit, a small number of electrodes are therefore sufficient to enable separation over the entire height and width of the filter unit.
  • precipitation electrodes and counter electrodes are arranged alternately in the separation unit and the precipitation electrodes and counter electrodes represent plates that extend perpendicular to the bottom of the housing of the filter unit.
  • the number of electrodes that must be provided in the separation unit is greater than in the embodiment with electrodes arranged parallel to the bottom.

  • the comb profiles can be attached to the housing in a simple manner.
  • the comb base which connects the plates of the respective comb profile to one another, also ensures the The stability of the filter unit is improved overall.
  • the interlocking of the comb profiles means that the collecting electrodes and counter electrodes are arranged alternately.
  • an ionization element is arranged in the ionization unit, which extends parallel to the bottom of the housing. Particularly preferably, only a single ionization element is arranged in the ionization unit. This further simplifies the structure of the filter unit.
  • the ionization element can extend over the entire width of the housing of the filter unit and therefore only needs to be attached to the longitudinal ends.
  • an ionization element running perpendicular to this ensures that the air that enters between the plate-shaped electrodes has been reliably ionized in the ionization unit beforehand, i.e. that the contaminants in the air have been ionized.
  • the filter units according to the invention are provided in a detachable manner in the extractor hood, the modular structure of the extractor hood's filter system can be implemented in a simple manner.
  • the filter units can therefore be removed individually from the extractor hood, for example for cleaning purposes.
  • the filter units are arranged in an extraction gap.

  • a fan which can also be referred to as a blower, is arranged in the extractor hood housing.
  • At least two filter units are arranged adjacent to one another in the suction gap. This allows the size, in particular the width, of the individual filter elements to be kept small and they can therefore be handled easily. For example, the weight of a filter unit that is smaller in size is lower and the filter unit can therefore be removed from the suction gap without great effort.
  • filter units are arranged next to each other in the extraction gap that all the air that can be sucked into the extractor hood via the extraction gap is guided over the filter units. Since the filter units each have a housing and this is formed on the side walls by airtight walls, filter units can also be arranged at an angle, i.e. they are adjacent so that the respective rear end of a side wall of two filter units rests against each other.

  • the filter units can also be connected to the extractor hood via mechanical connecting elements.
  • the filter units can, for example, have locking devices that interact with other locking devices on the extractor hood and the filter units are thus attached to the extractor hood.
