PURPOSE:To enable to set a toasting period on and after the second time rather short by a user by making brightness of indication into an aim in such case when bread is toasted continuously, by making indication in relation to a temperature in the inside of casing. CONSTITUTION:When a timer 3 is turned ON and a heater 2 is electrified, a neon glow lamp 13 is lit. Then it becomes that though the neon glow lamp 13 is kept lighting even if the timer 3 is turned OFF, brightness of the neon glow lamp 13 is reduced little by little along with the lapse of time after the timer 3 has been turned OFF and it is turned OFF at last. When discharge time constants of a condenser 9 and resistors 10, 11 have been kept setting by making them hold a mutual relation to a heat radiation time constant of heat of the inside of casing of an oven toaster, it becomes that the neon glow lamp 13 is lit at the brightness about related to a temperature in the inside of the casing. |
