  • Locking devices 1020 and 1201 are also shown. Via the locking device 1021, the tubular element 102 can be connected to the interface 103 and locked there. The lower ring of the carrier element 101 is connected to the tubular element 102 and locked thereon via the interface 1020.
  • an air flow S which enters the air cleaner unit 1 from below and in particular via the interface 103 into the air guide unit 10, can escape to the sides via the distance between the rings 1010, 1011 of the carrier element 101 and via the in Figure 1 shown grille 15 and the odor filter 16 are released to the sides of the environment of the air cleaner unit 1.
  • the present invention provides an air guidance unit, which is also referred to as an air guidance unit, in which at least one further functional feature is integrated in the same component.
  • This multifunctional unit can consist of several components if there is more than one additional functional feature. Additional functions can be guaranteed in a simple manner, for example via clip-in additional elements, which can also be referred to as small parts.
  • the air routing unit according to the invention is used for the targeted routing of air into and in the air treatment room and in particular in the reaction room.
  • the reaction space here designates the space in which the energy for treating the air is provided.
  • the air can thus be directed along the electrodes to generate a DBE plasma, for example.
  • the invention is not limited to air cleaner units for active odor removal, for example by means of plasma, catalysts or UV, but also relates to the air flow, for example in an activated carbon filter unit. In the present invention, the activated carbon filter can therefore flow evenly and be loaded with it.
  • a further air duct unit after the air cleaner unit is possible according to the invention. Such an additional air duct can ensure that the air flows out in a particularly low-resistance and low-noise manner. In all cases, the optimization of flow and odor removal is in the foreground in the present invention.
  • the air guidance unit is designed such that it has or can perform at least one further function.
  • at least part of the air guiding unit provides one or more carrier elements for the electrodes for plasma generation.
  • This carrier element, these carrier elements or additional tube elements can also be used, for example, for filters, catalyst material and / or sensors. Since the functional elements, such as electrodes, filters, catalyst material and / or additional elements, such as sensors, are held on the carrier elements or tubular elements, these are also referred to as holding devices.
  • the electrodes to be flown can be optimally fixed in relation to the air flow.
  • the electrical insulation (sufficient creepage distances or the like) can be ensured.
  • a further integrated carrier element or tubular element of the air guiding unit can for example contain a sensor or this can be attached to the carrier element or tubular element.
  • the sensor can represent an ozone sensor, for example. This enables the function of the air cleaner unit to be monitored and guaranteed. With a suitable design and arrangement of sensors, a safety function can also be easily integrated into the air cleaner unit.
  • the entire air duct unit can be designed as a supporting structure of the air cleaner unit.
  • Additional functions which may also require plug-in components, for example, are conceivable.
  • Intervention protection can be integrated into the air cleaner unit. This can be done, for example, by means of an attachable grid that encompasses the electrodes.
  • a flap can also be integrated into the air guide unit, possibly via a plug-on tubular element.
  • the air routing unit can be designed such that, for example, cables to sensors or electrodes are routed in a targeted manner. In this way, high-voltage lines can be spatially separated from low-voltage cables.
  • the cables can be guided, for example, by suitable fastening devices on one or more of the carrier elements or tubular elements of the air duct unit.
  • a housing for electronic components can, for example, connect to the air duct unit and be closed off by means of a plug-on cover.
  • a specially designed interface to the extractor hood of the extractor device in or with which the air cleaner unit is to be operated is also within the scope of the invention. This ensures that only extractors approved for the combination can be combined with the air cleaner unit. These special extractor hoods can be checked for their function and safety with the air cleaner unit, which increases the benefit for the user. In this case, the counterpart on the extractor hood must also be designed accordingly.
  • the interface can be configured, for example, in such a way that the air guidance unit is equipped with a sensor that detects a magnet attached to the extractor hood in the connecting part, which can be, for example, an exhaust air connection.
  • the air cleaner unit When combined with an extractor hood that is not approved for combination with the air cleaner unit, the air cleaner unit receives no signal from the hood and cannot be operated if the electronics are designed accordingly.
  • mechanical locking or coupling to an electromagnetic switch between the extractor hood and the air cleaner unit is also conceivable.
  • the air cleaner unit combines the optimization of the flow conditions with the function of carrier elements in which functional elements, for example for air purification, in particular filters or electrodes, are arranged in an optimized manner with regard to their functions. This enables the delivery volume, the reduction of noise and odor elimination to be optimized. Additional functions of the air cleaner unit, which can be implemented by additional elements, can serve, for example, the safety of the user.
  • the present invention has a number of advantages.
  • an air cleaner unit is created for use in combination with extractor hoods, in which the air flow can be guided in a certain way in the air treatment room, and in particular in the reaction room.
  • other functions can be linked to the air cleaner unit, such as, for example, the inclusion of certain components, which are also referred to as functional elements, and for example electrodes for generation of a DBE plasma.
  • the air cleaner unit according to the invention makes it possible to create a defined interface to the extractor hood.
