Abstract

PURPOSE: To save energy consumption, by lowering revolutions of a blower when room temperature is getting closer to a set temperature, while increasing the revolutions in the opposite case, and stopping the revolutions when the temperature exceeds the set range.
CONSTITUTION: A signal of a thermistor 1, which detects room temperature, and that of a variable resistor 4, which a user sets, are put into an amplifying circuit 9 together with an output of a maximum voltage setting circuit 8, and the output is put into an input terminal B of a comparing circuit 13 together with the output of a minimum voltage setting circuit 12, and a stopping circuit 19 is connected between the circuits 9 and 13. The output of a waveform as compared with the waveform of a reference potential generating circuit 14 is put into a blower driving circuit 16 through a pulse control of a blower 17. Revolutions of the blower 17 are varied by room temperature, while the output potential of the circuit 19 rises when the revolutions exceed a set range, and the potential of an output terminal C goes up as high as to a DC power source voltage 3 and the blower 17 stops.
