ABSTRACT:
The device eliminates water droplets from adhering to an evaporator of an automotive air conditioner after the vehicle as been shut off or stopped. In order to park a vehicle, a vehicle driver switches off an ignition switch device, which also switches off an accessory switch, unfastens a seatbelt, and exits the vehicle. Thereupon, after switching off of the accessory switch, when time t elapses, a control circuit sequentially executes a series of steps to recognize the parked state from the three conditions of switching off of a seatbelt switch, a no-rider signal of a rider sensor, and switching off of a door-lock switch. Thereupon, the control circuit announces operation of a blower by means of a notification device, then sets various dampers so as to enable an inner air intake mode, heater core bypass mode, and face mode, and operates the blower at high. Thereupon, water droplets adhering to an evaporator are blown away and removed by means of blown air from this blower.
