Abstract

PURPOSE: To improve safety, by detecting the full wave AC voltage between main electrodes of the switching element, which controls the heating wire, to stop feed for the short circuit trouble of the switching element.
CONSTITUTION: The output of temperature detecting circuit A including a thermosensitive element is sent to temperature adjusting circuit B, and the output makes switching element 6 conductive to control electricity supply to heating wire 5. Voltage detecting circuit C detects the full wave AC voltage of the switching element synchronously with the output of temperature adjusting circuit B; and if the gate signal is not output from temperature adjusting circuit B, that is, a voltage is detected across main electrodes of the switching element when the switching element is not conductive, safety thyristor 4 is driven to heat resistance 3, and the temperature fuse is opened to stop feed to heating wire 5.
