Abstract:
A smell generation time predicting device is used for a vehicle air conditioner which includes an evaporator (30) installed in an internal path (12) of an air conditioner case (10) and configured to, when the air conditioner is turned on, cool an air blown into a vehicle room. The device includes first and second temperature detectors (50 and 52) and a control unit (70). The first and second temperature detectors (50 and 52) are installed at a downstream side of the evaporator (30) in a mutually spaced-apart relationship. The control unit (70) is configured to, when the air conditioner is turned off, predict a smell generation time in the evaporator (30) depending on a temperature difference between the air temperatures detected by the first and second temperature detectors (50 and 52).
