Definitions

  • the invention relates to an air guidance system for a recirculating air extractor hood.
  • the invention also relates to an extractor hood system with such an air guidance system.
  • Such air guidance systems are known, for example, from the DE 84 23 193 U1 and the DE 85 00 413 U1 , the DE 87 01 860 U1 and the DE 1 757 656 A1 .
  • the flexible design of the casing enables a meandering arrangement of the air guiding elements, especially in the base area of a kitchen unit. This allows the available space to be used in the best possible way.
  • the pressure resistance of the air duct system is at most 200 Pa, in particular at most 150 Pa, preferably at most 120 Pa, for a flow rate of 450 m 3 /h.
  • the filter device is arranged in the flow area.
  • the filter device can be introduced, in particular plugged, into the flow area. It is replaceable.
  • the filter device can be fixed in particular in the flow area. It can, for example, be locked into the air guide element. In particular, it has a defined end position in the air guide element.
  • the filter device By arranging the filter device in the flow area, the flexibility of the air duct system is further improved.
  • the air duct system is also suitable for other applications, in particular for living space ventilation and/or exhaust ventilation.
  • the air guide elements can be identical on the outside. In particular, they can have an identical shell. They differ particularly on the inside. This is explained in more detail below.
  • the connectable design of the air guiding elements enables a flexible extension of the air guiding system.
  • connection between two air guiding elements can be designed as a plug connection, in particular as a bayonet connection.
  • Flanges can also be used as connecting elements.
  • the flanges of two adjacent air guide elements can be screwed together.
  • Connecting clamps can also be used as connecting elements.
  • connection between adjacent air guiding elements can be airtight.
  • the connection can be sealed airtight. It can be taped, for example.
  • a sealing agent provided for this purpose can be used for sealing.
  • a labyrinth formation can also be used for sealing.
  • the air guiding elements can have a variable length in the flow direction. They can in particular be shortened, in particular shortened as desired.
  • the connecting element can be placed back on the end of an air guiding element after it has been shortened, in order to connect it to other air guiding elements and/or other components.
  • the casing forms a filter element of the filter device.
  • it forms an active component of the filter device.
  • the casing itself has a filter function.
  • it can serve as a chemical and/or electrical filter. Due to the filtering effect of the casing, the air on opposite sides of the casing has a different concentration of at least one substance to be filtered out.
  • the casing has at least one region made of an organic material and/or a plastic and/or a metal and/or a ceramic. It can also be formed entirely from such a material or a combination of these materials.
  • one or more sensors are integrated into the casing.
  • the sensors can be used to detect different parameters of the air flowing through the casing.
  • the air guiding elements have mechanical support means which ensure a minimum flow cross-section A min .
  • the support means can be designed as separate elements which can be inserted into the interior of the air guiding elements if required. They can also be integrated into the air guiding elements, in particular into the casing.
  • the support means are designed in particular in such a way that they ensure a minimum flow cross-section up to at least a predetermined load on the air guiding elements in the direction of flow.
  • the minimum flow cross-section A min is ensured by the support means in particular over the entire length of the air guiding elements in the direction of flow.
  • a further object of the invention is to improve an extractor system.
  • filters may also be necessary to remove filters from the system for maintenance purposes.
  • filters usually take up a considerable amount of space, which is then no longer available for other components, such as drawers. All of this makes the arrangement of the filters in an extractor system difficult.
  • the shell 14 is formed.
  • the air guiding elements 11 are thus designed like hoses. They are formed in particular by hose elements.
  • the air guiding elements 11 have in particular a round or oval outer contour. Due to the flexibility, the air guiding system 1 can be laid in a meandering shape. This makes it possible in particular to use the available space, in particular in the base area 2 of the kitchen furniture 3, as efficiently as possible.
  • the filter device 15 is arranged in particular in the interior of the respective air guiding element 11, in particular in its flow area 13.

  • the number of air guidance elements 11 of the air guidance system 1 can in principle be increased as desired by adding further air guidance elements 11.
  • at least two and up to five air guidance elements 11 can be arranged parallel to one another. In principle, this makes it possible to increase the filter system as desired by adding further air guidance elements 11.
  • Adjacent air guide elements 11 can also be connected to one another via plug connections.
  • the plug connections can in particular be designed as a bayonet connection.
  • adjacent air guide elements 11 can also be designed so that they can be screwed directly into one another. In this case, they preferably have an external thread at one end and a matching internal thread at the opposite end.
  • the air guiding elements 11 can be connected to a flow channel or to the fan 10 directly or by means of an adapter.
  • One or more sensors may be mounted in or on the cover 26.
  • the casing 14 can be designed in one or more layers. In particular, it comprises a plurality of layers with different functions.
  • the cover 14 has in particular at least one area made of a fabric and/or a knitted fabric and/or a felt and/or a foam. It can also have at least one area made of an organic material and/or a plastic and/or a metal and/or a ceramic.
  • air guiding elements 11 are shown as examples, the outermost layer 18 of the cover 14 of which consists of a fabric with an antibacterial coating, in particular with silver oxide.
