The blower is operable independently of the blower of an air conditioning device of the vehicle. The ionization device is integrated into a functional component located in the passenger compartment.

The invention is based on the object to provide an ionization device and a ventilation arrangement with such an ionization device, which can perform additional functions with the same space requirements.

According to the invention, this object is achieved by providing an ionization device having the features of patent claim 1 and a corresponding ventilation arrangement having the features of patent claim 9. Advantageous embodiments and further developments of the invention are specified in the dependent claims.

In order to provide an ionization device and a ventilation arrangement with such an ionization device, which can perform additional functions with the same space requirements, a vent of a scenting system is integrated into at least one emitter unit and introduces perfumes in an air duct.

The high voltage generator may have an evaluation and control unit. In this case, the evaluation and control unit can control the high-voltage generator for generating a high-voltage current pulse, by means of which the ions in the region of the at least two electrodes can be generated.

Advantageously, the vent of the scenting system can introduce a perfume in the air duct or in the air flow. As a result, the at least one emitter unit can also introduce the fragrance into the air stream in addition to the ions. This can be saved in an advantageous manner space in the air duct.

In this case, the evaluation and control unit can assign the determined sensor data to the corresponding sensor and the corresponding emitter unit or the corresponding air channel.

In an advantageous embodiment of the ventilation arrangement according to the invention, the evaluation and control unit can output the measurement data to a bus system. In this case, the bus system can provide the first sensor data and / or the second sensor data for further vehicle systems, such as an air conditioning system. The ventilation arrangement may have a plurality of air channel exits with corresponding air duct vents. In the air ducts of the ventilation arrangement emitter units with integrated vents of the scenting system and emitter units can be installed without integrated outflow of the scenting system. In addition, emitter units can be installed with and without the at least one first sensor and / or the at least one second sensor. The evaluation and control unit can detect in an advantageous manner, in which air duct an emitter unit with outlets of the scenting system and / or with the at least one first sensor and / or the at least one second sensor is installed, or in which air duct an emitter unit without outflow of the Scenting and / or without the at least one first sensor and / or the at least one second sensor is installed.
