    DETAILED DESCRIPTION OF THE DRAWINGS

    [0024] A ventilation system 2 in a vehicle 1 will be described in detail hereunder by means of FIGS. 1 to 4.

    [0025] FIG. 1 shows the vehicle 1 having the ventilation system 2 disposed therein. The ventilation system 2 comprises an air guide unit 3 and a fan 5. The air guide unit 3 leads from the fan 5 up to an air outlet 7 of the ventilation system 2. For the sake of simplicity, only one air outlet 7 is shown here. In fact, the air guide unit 3 can also branch out to a plurality of air outlets 7.

    [0026] The air can flow into a vehicle interior 4 by way of the at least one air outlet 7.

    [0027] The ventilation system 2 according to the detailed illustration in FIG. 2 comprises an ionization device 6 in the air guide unit 3. The ionization device 6 is configured for ionizing the air that flows in the direction of the vehicle interior 4.

    [0028] FIG. 2 furthermore shows that a deflection device 8 is disposed at the vehicle-interior-proximal end of the air guide unit 3. The deflection device 8 is configured for directing the airflow in a specific direction in the vehicle interior 4.

    [0029] To this end, the deflection device 8 comprises at least one field-generating element 10 for generating an electric and/or magnetic field. In the example shown, there are two mutually opposite capacitor plates between which the air flows and is deflected.

    [0030] A current and/or a voltage on the field-generating element 10 is varied by way of the control unit 9 which is schematically illustrated in FIG. 1, so as thus to also vary the field and consequently the deflection of the air.

    [0031] FIG. 3 shows a variant of the deflection device 8 having an actuator 12. One of the field-generating elements 10 here is able to be moved by way of the actuator 12. The direction and/or the intensity of the generated field can be varied by moving the field-generating element 10. The direction of the flowing air is also varied on account thereof.

    [0032] FIG. 4 shows a further variant of the deflection device 8 having an actuator 12. In this example, the deflection device 8 comprises a field-impedance element 11 in the field. The field-impedance element 11 here is an electric isolator, for example. The field-impedance element 11 can be moved in the field by way of the actuator 12, on account of which the field and thus also the deflection of the air is varied.

    [0033] The figures furthermore show the optional use of a neutralizing device 13 which enables the ionization of the air downstream of the deflection device 8 to be further reduced.

    [0034] FIG. 5 shows a variant of the deflection device 8 having two field-generating elements 10 which, in the form of semicircular capacitor plates, are disposed so as to be centric. The two field-generating elements 10 here can be supported on a centric part of the housing of the air outlet 7, for example. It is in particular provided in this variant that the housing of the air outlet 7 is metallic, in particular on the inside. This takes place, for example, by way of a metallic coating. The housing of the air outlet 7 is electrically charged by way of the two field-generating elements 10 so as thus to achieve the desired deflection of the ionized air.

    [0035] FIG. 6 shows a variant of the deflection device 8 having a multiplicity of field-generating elements 10. In particular, more than two field-generating elements 10 are disposed so as to be transverse to the flow direction. Moreover, more than two field-generating elements 10 are disposed along the flow direction. The field-generating elements 10 here are individually actuatable such that, depending on the actuation, a plurality of paths 15 in which the ionized air can be directed result. In the example shown, field-generating elements 10 are disposed so as to be transverse to the flow direction, on account of which, depending on the actuation, three paths 15 for directing the air result.

    [0036] FIG. 7 shows a variant similar to that of FIG. 6. With a view to a simple design embodiment, it is shown in FIG. 7 that a plurality of the field-generating elements 10 can be actuated in groups.

    [0037] FIGS. 6 and 7 in an exemplary manner for all variants furthermore show the optional use of a flow rectifier 14. The flow rectifier 14, for example on account of the geometric design embodiment thereof having deflector elements, distributes the flow at the beginning of the air outlet 7 to the entire diameter.

    [0038] FIG. 8 shows a variant of the deflection device 8 in which more than two field-generating elements are disposed in the center of the air outlet 7. This plurality of field-generating elements 10 here conjointly form in particular an annular shape or a spherical shape and are actuatable individually or in groups.

    [0039] FIG. 9 shows a variant in which the deflection device 8 on account of a honeycomb-shaped structure subdivides the cross section of the air outlet 7 into a multiplicity of individual air ducts. As is in particular shown in the detailed illustration in FIG. 10, a plurality of field-generating elements 10 are present in each individual air duct and thus in each individual “honeycomb cell”. On account thereof, a dedicated field can be generated in each individual air duct, and the flow can be deflected in each individual air duct, or in each individual honeycomb cell, respectively.
