Abstract
PURPOSE: To provide a triggering method of power control element capable of operating AC load exactly and safely in the temperature control unit used in an electric blanket.
CONSTITUTION: The control unit consists of the control power circuit 19 connected with the noise filter 15, temperature setting circuit 26 containing the volume 27 the resistance of which is varied by the temperature setting control 9, temperature detecting circuit 29 containing the temperature sensor 7 and pulse transformer 33, and control circuit 41 composed of IC that is the core of control. Said control circuit 41 with a zero-pulse generator that produces zero-cross pulse at the zero-cross point of AC wave form of AC supply detects temperature in either of positive and negative half cycle of AC supply, and is made up in the two-bit triggering system such that it emits zero-cross pulses at the point a half cycle of temperature detection terminates and at the next zero-cross point.
