  • VEHICLE
    Publication number: 20130012116
    Abstract: Provided is a vehicle capable of increasing a concentration of ions in a vehicle without increasing the number of ion generators installed. The vehicle (1000) includes: a plurality of air-conditioning air blow-off outlets (500) and air blow-off outlets of ion generators (100). The plurality of air-conditioning air blow-off outlets (500) are configured such that in the air-conditioning air blow-off outlet (500), among the air-conditioning air blow-off outlets (500), which is located such that an air current blown off from the air-conditioning air blow-off outlet (500) intersects or neighbors an air current blown off from the air blow-off outlet (500) of the ion generator (100), a speed of the air current blown off from the air-conditioning air blow-off outlet (500) is made lower than a speed of an air current blown off from the other air-conditioning air blow-off outlet (500).
