Abstract

PURPOSE: To allow the current of a heater not to flow even if a power source is restored at power failure by connecting one end of a timer circuit to the load side of a contact of a relay.
CONSTITUTION: When an operation knob 8 is turned, points 7a-7c, 7b-7d between the terminals and the contacts of a controller 7 are closed respectively. When a start switch 11 is pushed to close its contact, the currents of a heater 6 and a timer circuit 9 are allowed to flow and at the same time the contact of a relay 10 is closed with the use of the signal from the timer circuit 9. Here, when the current of the heater 6 is cut off curing electricity supply by power failure and the like, the operation of the timer circuit 9 stops and the relay 10 is in an open state in hand with it. Even if a power source is restored be cause the relay 10 is in the open state, the current of the timer circuit 9 is not allowed to flow. Accordingly, the current of the heater 6 is not allowed to flow. In order to allow the current of the heater 6 to flow again, the start switch 11 is pushed to operate the timer circuit 9 and the relay 10 again.
