PURPOSE:To prevent an inflow of offensive smell, by forming a release flow path, which connects the upstream of an inside and outside air switching door with the downstream of an evaporator, in parallel with an air flow path and constituting an air conditioner such that air in a car is forcedly discharged for a fixed time to outside the car through the release flow path when a blower fan is turned on. CONSTITUTION:If a blower fan 20 is turned on, an air conditioner respectively sets a door 14 to a position A and an outside release door 32 to a position C while places an air mixing door 41 in a position E. Accordingly, feed air is released to outside a car through an evaporator 31 from a bypass duct 6 via the first connection opening 17. Here the evaporator 31, being operated, lowers also a temperature of the air, and an offensive smell is simultaneously discharged. After a fixed time, the positions of the doors 14, 32 are automatically set to a normal condition. By this constitution, the offensive smell can be perfectly eliminated. |
