Safety circuit for electronic cooker

摘要

The safety circuit for an electronic cooker has a control unit(3) which directs change-over operational signals directly or indirectly to a master switch(1). If a signal is absent for a certain time, the master switch is activated automatically. It is joined to a mains supply component (2) that feeds the control unit. The control unit feeds the signals to the master switch via a load control unit (4). The master switch switches off the mains supply when no cooking hob is being used, when the control unit has no defined working mode or if a fault occurs.
