<p>This invention relates to a vehicle atmosphere purifying apparatus. An object of the invention is to provide a DOR system that enables suppression of a decrease in ozone purifying performance caused by water adhesion and restoration thereof. As an ozone purifying body, activated charcoal is coated on a core portion of radiators 14 and 16 and a capacitor 18, respectively. If water adheres to pores of activated charcoal or areas surrounding the pores, ozone becomes hard to enter mesopores and micropores. Even if ozone enters, an electron becomes hard to donate from the activated charcoal to the ozone. Consequently, the performance of the activated charcoal decreases while water is adhered thereto. When an amount of moisture adhered to activated charcoal is equal to or greater than a predetermined amount, moisture desorption control is executed that forcibly heats the activated charcoal to a high temperature to desorb the moisture therefrom.</p> |
