PURPOSE:To effectively enhance the warm feeling of a passanger compartment, by controlling an air-conditioning system in such a way that the blow-out direction of ventilation air is started to be oscillated when the temperature of the vehicle compartment reaches a set temperature which is desired by the passanger. CONSTITUTION:A comparator 5A in an electric control circuit 5 issues an L level signal when the output of a temperature sensor 2 for detecting an air temperature in a vehicle compartment, indicates that the temperature of the vehicle compartment is higher than a set temperature set on a setting unit 1. Then, transistors Tr5D and Tr5E are turned off and on, respectively, to energize a relay 4, and therefore, a D.C. motor 3A in a swinging mechanism 3 is started to be energized. By the operation of this motor 3 a plurality of air deflectors 3C which are attached inclinedly to a shaft 3D and which are parallel with each other, are rotated to oscillate the blow-out direction 3F of air stream 3E. With this arrangement the passenger's warm feeling may be effectively enhanced. |
