VEHICLE AIR PURIFIER

WIPO Patent Application WO/2015/079753

A1

The purpose of the present invention is to provide a vehicle air purifier that can collect fine particles of dust without diminished convenience. This vehicle air purifier is provided with: an air passage (13) which allows communication between a suction port (11), which sucks in air from outside the vehicle or from the vehicle cabin (6), and a blow port (12), which blows air into the vehicle cabin (6); a fan (15) which is arranged inside of the air passage (13); a fine particle sensor (21) which detects the concentration of PM2.5 (fine particles) inside of the vehicle cabin (6); an ion generation device (18) which generates negative and positive ions; and a filter (14) which collects PM2.5 contained in air flowing through the air passage (13) and is charged with a prescribed polarity. This vehicle air purifier has a first emission mode in which the ion generation device (18) emits both negative ions and positive ions into the air passage (13), and a second emission mode in which the ion generation device (18) emits primarily ions of the polarity opposite that of the filter (14) into the air passage (13). If in the first emission mode the PM2.5 concentration in the vehicle cabin (6) exceeds a prescribed concentration, the vehicle air purifier switches to the second emission mode.
