PURPOSE:To make it possible to confirm easily a remaining combustion time by providing a timer which extinguishes fire after continuation of combustion for a certain time and providing an analog display section which analog-displays the remaining combustion time during the combustion by means of the timer. CONSTITUTION:A timer circuit 10 as a timer means outputs a combustion starting signal to a control circuit 9 when a desired time which a user has set up has come. A clock circuit 11, when combustion starting signal outputted from the timer circuit 10 is inputted to the circuit 11, performs a calculation to subtract a time of possible combustion which is beforehand set up and outputs a signal to output a remaining combustion time to a display section 12. The clock circuit 11 outputs a combustion discontinuation signal to the control circuit 9 when the time of possible combustion set up beforehand has elapsed. Because the display section 12 is arranged to analog-display a remaining combustion time in which the operation can be continued during timer operation, it is possible to confirm easily a remaining combustion time. |
