Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] A preferred exemplary embodiment of the invention is shown in the drawing and is explained in more detail in the following description.

[0014] The FIGURE shows a ventilation device according to the invention.

DETAILED DESCRIPTION

[0015] According to the FIGURE, a ventilation device 1 according to the invention, in particular for a motor vehicle 2, comprises a first air treatment device 3 and an ionizer 4 with an electrode 5. According to the invention, a counter-electrode 6 is now no longer part of the ionizer 4 itself, but electrically conductively connected to the first air treatment device 3 or a part of the same. In the embodiment of the ventilation device 1 according to the invention shown in the FIGURE, the first air treatment device 3 can be arranged upstream or downstream of the ionizer 4.

[0016] The first air treatment device 3 can be formed as a filter device, for example as an electrically conductive activated charcoal filter, as an evaporator, as a heat exchanger, as a PTC heating element or as a fan.

[0017] Likewise, a second air treatment device 7 can also be provided, wherein in this case the counter-electrode 6 cannot only be electrically conductively connected to the first air treatment device 3, but additionally also to the second air treatment device 7. By way of this, an electromagnetic field ionizing the air 8 flowing through the ventilation device 1 can be defined in two directions, namely from the ionizer 4 in the direction of the first air treatment device 3 and in the direction of the second air treatment device 7.

[0018] The second air treatment device 7 can be formed as a filter device, for example as electrically conductive activated charcoal filter, as an evaporator, as a heat exchanger or as a PTC heating element or fan. Purely theoretically it is even conceivable that a third air treatment device that is now shown is additionally connected to the counter-electrode 6 in an electrically conductive manner, so that between the ionizer 4 or its electrode 5 and the third air treatment device an electromagnetic field ionizing the air 8 can also be defined.

[0019] By ionizing the air 8, the dust-binding effect can also be significantly increased since the charged ions settle on dust particles in the air 8 and, through their electrostatic interaction, promote a cluster formation of dust particles. Such enlarged dust particle clusters can then be better filtered out in an air treatment device 3, 7 arranged downstream of the ionizer 4, than for example individual particles. Because of this, both a degree of separation and also a cleaning performance of the ventilation device 1 can be increased.

[0020] Besides the dust-binding effect, the ozone created during the ionization of the air 8 can also be utilised for neutralising odour-forming molecules since the highly reactive ozone decomposes and thereby neutralises such odour molecules. In addition, ozone also has an antibacterial, fungicidal and antiviral effect, as a result of which the air inside a passenger compartment of the motor vehicle 2 can be likewise improved. Here, the electrode 5 and the counter-electrode(s) 6 are electrically conductively connected to a control unit 9, by way of which a high voltage is applied to the electrode 5 or the counter-electrode(s) 6.

[0021] Here, the counter-electrode 6 can be a simple electrically conductive part of the first air treatment device 3 and/or of the second air treatment device 7, for example even a housing part of the same. Here, the ventilation device 1 according to the invention can also be parts of an air-conditioning system 10 of a motor vehicle 2. With the ventilation device 1 according to the invention, in particular a reduction of the installation space and a reduction of the costs because of a reduced cabling expenditure and also an increase of the efficiency can be achieved.
