CARBURETOR TEMPERATURE CONTROL DEVICE FOR FAN-HEATER

摘要

A temperature control apparatus of carburettor for fan heater having a low voltage discriminating circuit(11) sensing power voltage inputted through a power supply circuit(2) and outputting the voltage corresponding to the low voltage determination by comparing it with constant basic voltage; a low temperature discriminating circuit(12) sensing carburettor temperature through a carburettor temperature sensing circuit(3) and outputting the temperature corresponding to the low temperature determination by comparing it with constant basic temperature; and a carburettor temperature control circuit(13) is disclosed. Signal corresponding to power low voltage is inputted to said carburettor temperature control circuit(13) through said low voltage discriminating circuit(11) in preheating completion and ignition of the carburettor. Further, prescribed signal corresponding to the low temperature of the carburettor is inputted to said carburettor through the low temperature discriminating circuit(12). Thereby, it is possible to remove bad ignition which can be occurred in using fan heater in cool provision or low voltage provision, thus to enhance reliability.
