Definitions

  • filter elements that filter out grease and other contaminants.
  • the filter elements are therefore also referred to as a grease filter.
  • filter cartridges are used as filter elements, in which a filter material is held in a filter frame. These filter elements are inserted into the suction opening of the extractor device and optionally attached via pin connections. For this purpose may be provided on the filter elements in the surface of the filter material, a handle over which the pins of the pin connection can be moved.
  • a disadvantage of these embodiments of the filter elements is that the user has to attack the filter element itself in order to remove it from the extractor device, for example for cleaning.
  • the invention is therefore an object of the invention to provide a filter unit, by means of which on the one hand, the cleaning of the air can be done reliably and on the other hand is easy to handle.
  • the object is achieved by a filter unit for a fume extraction device which has at least one filter element and at least one filter holder.
  • the filter unit is characterized in that the filter holder has a base plate with at least one handle, and at least one holding frame, which is arranged inclined to the base plate and rigidly connected to the base plate, and in each holding frame at least one of the filter elements, in particular a filter element, is held.
  • a filter unit for a fume extractor As a filter unit for a fume extractor according to the invention a structural unit is referred to, which can be used on or in a suction port of the extractor device and by means of which the air can be freed of impurities.
  • the filter unit has at least one filter element.
  • the filter element may comprise filter material held in a filter frame.
  • the filter element consists exclusively of filter material.
  • the filter material can be, for example, expanded metal layers, a nonwoven fabric, a knitted fabric or a knitted fabric.
  • the filter material may consist of wire.
  • the filter unit according to the invention has a filter holder. The filter holder serves, on the one hand, to hold the filter element or elements on the extractor device and, on the other hand, to hold the filter element (s) on the filter unit during removal from the extractor device.
  • the filter unit is characterized in that the filter holder has a base plate and at least one holding frame.
  • the base plate has at least one handle.
  • the handle may be formed in the base plate and / or comprise a separate grip element which is connected to the base plate.
  • the holding frame represents a receiving framework in which at least one filter element is held.
  • the holding frame surrounds at least a part of the edge of the filter element.
  • the holding frame is rigidly connected to the base plate. At least part of the support frame can be designed, for example, in one piece with the base plate.
  • the holding frame is arranged inclined to the base plate.

  • the holding frame is arranged inclined to the base plate, a number of advantages can be achieved.
  • the handle is provided on the base plate and it is inclined to the support frame, the user can grasp the grip without coming into contact with the filter element held in the support frame.
  • the filter holder has at least two holding frames. Due to this configuration of the filter holder, it is possible for a plurality of filter elements, which are held in the holding stands, simultaneously from the extractor device to remove and insert into this. The removal of the filter unit from the extractor device may be required, for example, for cleaning purposes or for maintenance purposes. The filter unit can be removed as a component and cleaned, for example, in a dishwasher.

  • the filter unit in a simple manner in a, for example, in an intake opening lying below the suction fume extraction device, are inserted and removed.
  • the handle can remain largely free of grease, since it is not in the inflow region of the filter unit.
  • the Anström Society which can also be referred to as Wrasen Berlin is rather formed by the holding frames with the filter elements held therein. If a plurality of holding stands are provided, each with at least one filter element, then each of the holding stands forms an intake area of the filter unit.

  • the connection between the frame parts can be achieved for example by gluing, welding or latching.
  • a first of the frame parts of the holding frame with the base plate is designed in one piece and a second of the frame parts is connected to the first frame parts.
  • the production is further simplified, since in the production only the filter element or elements and the second frame part have to be aligned. Due to the one-piece design of the first frame part with the base plate, the frame part is firmly connected to the base plate. The position of the rigidly connected to the base plate frame part, however, is fixed. The one or more filter elements can thus be applied or inserted on the fixed frame part. Subsequently, the second frame part can be applied to the other side of the filter element and this then be connected to the first frame part.
  • the frame parts preferably have a fold at their edges, by which the frame parts each form a receiving space.
  • the frame parts preferably have a fold at their edges, by which the frame parts each form a receiving space.

  • the filter material is preferably clamped between the strips of material of the frame parts surrounding the opening.
  • one of the frame parts of the holding frame constitutes an inner frame and a frame part forms an outer frame.
  • the outer frame or the inner frame can be rigidly connected to the base plate and in particular can be designed in one piece therewith. If the outer frame is rigidly connected to the base plate, the filter elements are or are placed from the inside into the outer frame and then pressed by applying the inner frame from the inside against the outer frame and held after attachment of the inner frame to the outer frame between them. If, however, the inner frame is rigidly connected to the base plate, so or the filter elements can be placed from the outside in the outer frame. From the outside of the outer frame is then applied to the filter elements and connected to the inner frame.
