PURPOSE:To secure the mutual switching between blowing-out modes by the operating means in the quantity less than that of modes by installing a means for generating the third switching signal necessary for the switching to the third blowing-out mode when the first and the second operating means are operated. CONSTITUTION:When blowing-out mode is switched to the third mode HEAT- DEF, operating switches 13 and 14 are closed, and then an AND-gate 15e generates the HEAT-DEF mode switching signal, corresponding to the HEAT and DEF mode switching signal, and said signal is transmitted to a driving mechanism 20. Then, the electromagnetic coil of a relay 22 is excited by receiving the HEAT-DEF mode switching signal through a fixed contact 21f and a conduction pattern 21a, and a motor M is normally driven, and the both conduction patterns 21a and 21b shift upward. Then, the fixed contact 21f is intercepted from the pattern 21a, and the relay 22 suspends the operation of the motor M, and the contact 21f is cut-off between the patterns 21a and 21b, and said state is maintained, and switching to HEAT-DEF mode is performed. Therefore, the quantity of operating means can be reduced in comparison with that of modes. |
