Abstract
When a power switch of a blower and a second mode switch are both turned on, a door at the exit of a deodorizer containing a volatile deodorant is opened to allow the deodorant to volatilize and diffuse into an air blast duct through a passage extending between the deodorizer and the duct, whereby the deodorant deodorizes the air to be blown into the passenger compartment. The second mode switch is any one of the power switch for the air conditioning system, the power switch for a driving device to open and close the door, and the mode switch to select a upward blower outlet.
