Abstract

PURPOSE: To enable a cooking operation depending on an intended purpose by selectively using the high-speed rotation of a kneading vane at the time of bread baking, and the low-speed rotation of a turntable at a high-frequency heating process via a transmission drive part. CONSTITUTION: A transmission drive part 16 is laid on the inner bottom of a heating chamber 1 formed to use a high-frequency oscillator and upper and lower heaters as heating sources, and provided with the first drive shaft 17 driven with a kneading motor 23, and the second drive shaft 27 driven with a motor 22 for a turntable. In addition, the shaft 17 is coaxially positioned along the outer surface of the shaft 27. Also, the shafts 17 and 27 are both formed out of a high-frequency transmissive dielectric substance and held on a metallic bearing holder 33 fitted to the bottom outside of the heating chamber 1, a metallic bearing 29 fixed to the inner surface of the holder 33 and a sliding metallic cylinder 30 slidable on the inner surface of the bearing 29. In addition, a kneading vane 14 in a bread container 12 is connected to the shaft 17 and the turntable is connected to the shaft 27. The kneading vane 14 is rotated at high speed, or the turntable is rotated at low speed.
