Abstract

PURPOSE: To control heating electric power in such a way that heaters are provided on the upside and downside of a heating chamber, a commutating element is connected to the heaters.
CONSTITUTION: When a switch S1 makes to a contact b, in correspondence to makes of switches S2∼S4, heating of a steam heater 5a or upper and lower heaters 4a, 4b is done. When the switch S4 closes on the side of a contact g, alternating current voltage V is impressed upon the upper heater 4a. When the switch S2 closes on the side of a contact C, the switch S3 on the side of a contact e, and the switch S4 on the side of a contact h, commutating elements 14, 15 are respectively connected to the upper and lower heaters, the heaters have anti-phase half-wave commutating current flowing to each other. When the switch S2 makes on the side of the contact C, the swtich S3 on the side of a contact f, the switch S4 on the side of the contact g, the commutating element 15 is connected in series to the lower heater 4b, heating is doen by the half-wave commutating current.
