Device For Disinfecting Air With Electromagnetic Radiation

A device for disinfecting air with electromagnetic radiation, comprising:

• a radiation chamber with air flow along a flow path from an intake side to a discharge side;
• and
• at least one radiation source configured to generate electromagnetic radiation in a microwave range and to emit electromagnetic radiation into the radiation chamber, a frequency of the electromagnetic radiation is selected so that water molecules present in the air are excited to an oscillation that heats the water molecules, and the air flowing through the radiation chamber is exposed to the electromagnetic radiation and water present in the air is brought to a temperature of at least 100° C.;
• the device further comprises at least one fan with an impeller for generating an air flow through the radiation chamber, the fan is configured to take in air on the intake side, to convey it through the radiation chamber along the flow path to the discharge side and to blow it out of the radiation chamber on the discharge side;
• at least the impeller is arranged in the radiation chamber and the impeller has a plurality of blades that are formed at least in sections from a material that deflects or reflects the electromagnetic radiation.
