Abstract

Providing a control circuit (20) which performs ON/OFF control of a switch section (3) connected between an AC power supply (5) and a heater (4), wherein the control circuit (20) performs control to allow the present turning ON of the switch section (3) when it is determined that an AC power supply (5) waveform (i.e., AC waveform) polarity at a previous turning ON at the switch section (3) is not the same as an AC waveform polarity at a present turning ON; and wherein the control circuit (20) performs control to inhibit the present turning ON of the switch section (3) when it is determined that the polarities are the same.
