<P>PROBLEM TO BE SOLVED: To provide a temperature control mechanism for a plurality of firing furnaces in a multistage electric oven which can reduce the maximum power consumption due to ON/OFF control of the firing furnaces. <P>SOLUTION: An electric oven comprises: a plurality of firing furnaces 2; electrothermal heaters 10 arranged in the respective firing furnaces 2; temperature sensors 11 arranged for the respective electrothermal heaters 10; operation parts 7 capable of adjusting ON/OFF conduction temperature on the basis of temperature information detected by the temperature sensors 11; and a control unit 13 which enables control so that on/off states of the firing furnaces 2 do not overlap each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
