Definitions

  • the invention relates to a filter carrier for at least one odor filter element and an extractor hood with such a filter carrier.
  • odor filters such as activated carbon filters
  • these filters are, for example, enclosed in cassettes and inserted into a channel, in particular the chimney of the extractor hood.
  • a disadvantage of this arrangement of odor filters is that the inflow surface of the odor filter is low due to the small available space above the fan, in particular due to the small width and height.
  • Object of the present invention is therefore to provide a solution with which the available space above the blower can be used efficiently.
  • the invention is based on the finding that this object can be achieved by the at least one filter element is arranged inclined in the space above the fan of the hood to the flow direction of the outgoing air from the fan or the fan box in which the blower is arranged ,
  • the invention therefore relates to a filter carrier for at least one odor filter element for an extractor hood, wherein the filter carrier has at least one inlet surface for the inlet of air into the filter carrier.
  • the filter carrier is characterized in that the filter carrier has at least one filter receptacle for a filter element, which is arranged inclined to the input surface.
  • a filter carrier is understood to be a component on which at least one filter element can be held, in particular on or can be introduced.
  • the filter support is preferably a separate component, that is not pre-assembled with other parts of the hood.
  • the filter carrier can be subsequently provided in a fume hood and used for example as an additional part.
  • the filter support according to the invention also serves to guide the air to the at least one filter element.
  • an interior space is preferably formed in the filter carrier, to which the at least one filter element is adjacent.
  • the odor filter element that can be held in the filter carrier is also referred to below as a filter element.
  • the filter element has filter material which is suitable for absorbing odors.
  • the filter material may therefore comprise activated carbon and / or other suitable adsorbers.
  • the extractor hood in which the filter carrier is used, according to the invention may have any shape.
  • the filter carrier can be used in so-called food, which has a viewing hood and a chimney arranged above it.
  • the filter carrier for example in an extractor hood, which has a hood body, which is arranged in front of a cuboid base body and constitutes a channel.
  • At least one input surface for the entry of air into the filter carrier is provided on the filter carrier.
  • the surface of an opening is referred to as the input surface.
  • the opening may be provided in a wall of the filter support and in particular in the bottom of the filter support. Alternatively or additionally, the opening may be formed for example by a pipe socket which is fixed to a wall, in particular the bottom, of the filter support.
  • the input surface is in the mounted state of the filter carrier in the hood preferably in the horizontal.
  • a device which holds the filter element with respect to the input surface in a fixed position.
  • the filter holder can at least partially surround the filter element.
  • the filter receptacle represents a contact surface on the filter support on which the filter element can be placed.
  • the connection between the filter element and the filter holder is preferably designed so that it can be manufactured and released without tools.
  • the filter element can therefore be connected to the filter carrier by placing, latching, inserting or other releasable connection types.
  • the filter receptacle is designed such that they have at least partially an opening at the bottom and top.
  • the opening at the bottom is also referred to below as the inlet opening and the opening at the top as the outlet opening.
  • the filter element is provided in the filter holder so that the air inlet side at the inlet opening and the air outlet side abut the outlet opening. In this way, the filter element can also be flowed through in the recorded state in the filter holder of air.
  • the filter holder is arranged according to the invention inclined to the input surface of the filter carrier.
  • an arrangement of the filter holder at an angle not equal to zero between the surface of the input surface of the filter carrier and the surface of an inlet opening of the filter holder is referred to as an inclined arrangement.
  • the inlet opening designates the surface via which air from the filter carrier can enter into the filter holder and thus also into a filter element provided in or on the filter holder.
  • the air which enters the filter carrier via the input surface does not flow perpendicularly to the inlet opening of the filter receiver and thus to an air inlet side of the filter element. Damming of air at the inlet opening and thus the air inlet side can therefore be avoided.
  • the size of the inlet opening and thus the air inlet side of the filter element at given horizontal dimensions of the available by the inclined arrangement of the filter holder standing space in the cooker hood relative to a horizontal orientation of the filter holder can be increased. As a result, the efficiency of the air cleaning on the filter element can be increased.
  • the filter carrier on two filter receptacles which are arranged inclined to each other and to the input surface. Tilted in this context means that the inlet openings of the filter holder are not in one plane. As a result, the space required in the height direction is minimized. In the case of two filter receptacles arranged next to one another in a plane and inclined to the input surface, the inflow conditions in the region farthest from the input surface would also be adversely affected. The upper region of such an arrangement would then be so far away from the input surface that the flow velocity would be low there.
  • the angle between the inlet openings of the two filter receptacles is less than 180 °, preferably less than 90 °.
  • the height of the required installation space is relatively low in this embodiment.
  • the filter holder in this embodiment can be large and thus a large filter surface for filtering odors from the air can be provided.
  • the filter element can be attached or inserted on or in the filter holder in different ways.
  • at least one of the side surfaces, preferably the front side surface, of the filter receptacles is formed by an insertion opening for insertion of at least one filter element.
  • the filter receptacle is referred to as the surfaces which extend, preferably perpendicular, between the inlet opening and an opposite outlet opening of the filter receptacle.
  • the filter receptacle has a rectangular cross-section.
  • a front side surface is understood according to the invention, the side surface facing in the assembled state of the filter support in the hood forward, that is, facing the user.
  • one of the side surfaces represents an insertion opening
  • the filter element can be specifically introduced into the filter holder, in particular inserted, are.
  • no wall is provided on the side surface, which represents the insertion opening, or a correspondingly large recess is made in a wall.
  • the filter holder preferably has a box shape or cuboid shape.
  • the wall is recessed on only one side surface, for example, a box-shaped filter element is thus held securely after insertion from the other five sides.
  • a displacement of the filter element in the filter holder and with respect to the filter carrier can be prevented.
  • Such a shift would be to be feared for example due to vibrations caused by the fan of the hood.
  • the insertion opening is provided in the front side surface of the filter holder.
  • the removal and insertion of the filter element for the user is facilitated because it can access the front of the filter holder.
  • the height at which the filter element must be brought for replacement is lower, so that the user can optionally perform the filter replacement without tools, such as a ladder.
  • the filter carrier comprises a frame for holding the at least one filter holder.
  • the frame can be integrally formed with the filter holder or with the filter holders.
  • the filter holder it is also possible to use the filter holder to be provided as separate components, which are connected via suitable connecting means, such as tabs with the frame.
  • suitable connecting means such as tabs with the frame.
  • the orientation of the filter elements to the air flow in the hood can be specified and does not have to be adjusted by the user.
  • the provision of a frame also allows retrofitting or introduction of the filter elements in a cooker hood, without that structural changes are required. In particular, no guides for individual filter receptacles or individual filter element must be provided on the hood. The entire construction of the extractor fan simplifies this.
  • the input surface of the filter support which is preferably provided in the bottom of the filter support and in particular in the bottom of a frame of the filter support, may have different shapes.
  • the input surface may have a rectangular cross-section.
  • the input surface constitutes a round recess.
  • a round recess here is preferably understood as a recess with a circular diameter.
  • the odor filters are provided in extractor hoods, in particular above the fan and the fan box, in which the fan, which is also referred to as a fan, is arranged.
  • the fan box in this case generally has a rectangular shape and has at the top an outlet nozzle, which has a round cross-section.
  • the entrance surface also has a circular cross-section and has a diameter equal to or slightly greater than the outer diameter of the outlet nozzle.
  • the outlet nozzle can be introduced into the input surface.
  • the filter support can thus be placed on the fan box and is fixed by the introduced into the input surface outlet in the horizontal direction.
  • the present invention relates to an extractor hood, which is characterized in that it comprises at least one filter carrier according to the invention.
  • An advantage of the extractor hood according to the invention is that with this due to the orientation of the filter holder / filter receptacles in the filter support improved cleaning of the air of odors can be achieved. In addition, due to the arrangement of the filter recordings, the noise during operation of the extractor hood and the cleaning of the air is reduced.
  • the hood on a fan box and the filter support is placed on the fan box.
  • This embodiment which has already been described above, has the above-mentioned advantages.

  • the depth of the filter element is the dimension that extends in the introduced state into the filter carrier in the depth direction of the filter carrier and thus in the installed state of the filter carrier in the depth direction of the hood.
  • the width is correspondingly the dimension that extends in the introduced state into the filter carrier in the width direction of the filter carrier and thus in the installed state of the filter carrier in the width direction of the extractor hood.
  • the filter carrier is arranged in a facing part of the extractor hood.
  • the veneer part preferably represents a channel or a channel part.
  • the filter element is thus covered by the channel part during operation of the extractor hood and is therefore not visible to the user.
