Abstract

PURPOSE: To increase the temperature of an electric blanket, etc., according to the room temperature by providing a positive characteristic thermistor in a firing angle control circuit of SCR.
CONSTITUTION: Traveling contact 16 of switch A is changed over to fixed contact 17 to connect positive-characteristic thermistor 20 in parallel to variable resistor 15. With swith 2 closed, a trigger signal is applied to SCR8 by way of electric power source 1, temperature fuse 6, resistances 14 and 15, signal line 7, and the neon lamp, so that electric current will flow through heating line 5. According to the temperature of heating line 5, the impedance of heat-sensitive layer 4' varies to control the firing angle of SCR8, so that the temperature will be constant. As the room temperature drops, the resistance value of thermistor 20 decreases, and consequently the conduction angle of SCR8 increases, increasing the temperature of heating line 5.
