PURPOSE:To simplify constitution and permit the speedy heating free from environmental pollution by increasing the number of revolution of a blower when a heat exchanger for the heat exchange between combustion gas and the air-conditioning air has a high temperature than in case of a low temperature, in the captioned device for speedy heating for an internal-combustion engine car. CONSTITUTION:The combustion gas of a speedy ignition burner 4 radiates heat into the inhaled air 10 in a heat exchanger 5. The air having the increased temperature is sent into a blow-out port 11 from a discharge port 130by a blower 12. The signal of a thermocouple 112 installed into the heat exchanger 5 is input into a blower control circuit 100. When the temperature of the heat exchanger 5 rises, the signal of the thermocouple 112 becomes H level, and a blower controller 100 operates to increase the number of revolution of the blower 12, and the wind feed amount is increased. With such constitution, the control constitution is simplified,n environmental pollution is prevented, and speedy heating is permitted. |
