Abstract
PURPOSE: To perform temperature control circuit securing fail-safe characteristics by charging and discharging a capacitor in accordance with an output of AND between the output of zero pulse generator and temperature detection output, by smoothing the current and by driving a power control element by a transistor, etc.
CONSTITUTION: A temperature controller , used for an electric blanket, etc., consists of power plug 1, power switch 8, temperature fuse 14, power noise filter part 15, control power supply Vcc generating part 19, temperature setting circuit 26, temperature detection circuit 29 including neon lamp 32 and temperature sensor 7, control circuit 41 as a main part of control, charge-discharge circuit 90 for capacitor C96, direct-current relay 102, heater wire 48, etc. At eleven pins of circuit 41, an output apears at the zero-cross point of an alternating-current voltage to turn ON transistor Tr95 of circuit 90 for charge and discharge of C96, whose differential current is smoothed by C99 and the direct-current voltage is fed to Tr101 through resistance 100 to turn ON-OFF winding 103 of relay 102, so that temperature control will be done by turning ON-OFF heater wire 48 by its contact 70. Relay 102 operates only at the time of alternating operation and fail-safe characteristics are secured.
