PURPOSE:To shorten the time required for defrosting by allowing the duct line to diverge to the inside and outside of a glass, furnishing a control door at this divergent part, and by blowing warm wind against either or both of these inside and outside of the glass. CONSTITUTION:An inside blow-out 1 and an outside blow-out 2 are furnished so as to blow warm wind against the inside and outside of a windshield glass A. With the inside blow-out 1 is connected a heater device, which prepares a warm wind through utilization of the heat of engine and sends this through a duct system 3. With this duct system 3 is connected a divergent duct system 5, which is connected to the abovementioned outside blow-out 2 through another duct system 4. At this divergent part is installed a control door 6 rotatably, which is to shut either of the duct systems 3, 5 or open both simultaneously. Rotational position of the control door 6 can be automatically controlled by a collected- moisture sensor 7 and a frost sensor 8. |
