Abstract

PURPOSE: To control heating electric power by changing over connections between heaters and commutating elements in such a way heaters are provided on the upside and downside of a heating chamber, and the commutating elements are connected in series to each heater.
CONSTITUTION: When a switch S1 is closed on the side of a contact (a), a high frequency heater 1 works, and when the switch S1 makes on the side of a contact C, a steam heater 5a works, and when it makes on the side of a contact b, heater heating is done by an upper heater 4a and a lower heater 4b. When switches S2∼S4 are properly changed over, sole behavior of either upper or lower heater or series connection of the both upper and lower heaters, or otherwise in parallel connection is selected, the treatment of a heated object is done under respectively different heating electric power.
