Abstract

PURPOSE: To minimize a heat-insulating cover heater, obtain a considerable cost cut, and improve the productivity due to the simplification of the structre, without detracting the heat-insulating faculty.
CONSTITUTION: A heat-insulating cover heater 19 arranged in a cover body 17 is connected with a diode 22 in series, and with this circuit, a heat-insulating side heater 20 arranged on the outside surface of an inner vessel 12 is connected in parallel. With the junction point described above, is connected a controlling commutator 24 such as thyristor of which conduction is controlled by a controlling circuit 23, and with the junction point between the cover heater 19 and the diode 22, a diode 25 is connected in the reverse direction to the commutator 24. As the heater 19 always generates heat with the half of its electric capacity, and the turning ON-OFF of the commutator 24 allows the heater 19 to consume the power in turning-ON, the power consumption by the heater 19 is equal to the power consumption by former cover heater, and also the effect on the heat-insulating condition is the same
