Abstract
PURPOSE: For preventing initial overcurrent (rush current), to let current flow through diodes to a plurality of positive temperature characteristic resistors connected in parallel.
CONSTITUTION: Heating units 10 and 11 on one hand and 12 and 13 on other are connected in parallel to an AC power source 14, and diodes 15 and 16 are connected as diagrammed. Therefore, current flows alternately to resistor groups. Therefore, this heat generator requires only a half of the amount of the current requried by conventional ones of the kind. Thus, rush current can be prevented.
