摘要

PROBLEM TO BE SOLVED: To prevent mold and bacteria, adhered on an air supply fan, together with air-conditioning air from being transferred into cabin during restarting of air-conditioning operation. SOLUTION: An air introduction port 12 is formed in an end part situated down stream from a casing 2 for an air-conditioning device 1. A reverse air supply fan 13 is situated in the air introduction port 12 and outside air is introduced to an end part situated downstream from an air passage 3 through the air introduction port 12. Introduced air is heated by a heater 6. An evaporator 5 is dried by heated air. The dried air is discharged through a discharge passage 15 to an external part. Further, an opening and closing door 16 to open and close the air passage 3 is situated between the air supply fan 4 and the evaporator 5 so that the dried air is prevented from inflow to the air supply fan 4 side. The opening and closing door 16 is also used for opening and closing of the discharge passage 15.
