PURPOSE:To enable the automatic heating by a method wherein the weight of an object to be heated is measured, then a heating time, heating temperature, heating output and heating mode are controlled according to the measured weight. CONSTITUTION:At the loading of an object to be heated 28 on a rotary pan 26, the weight is applied to the free end of the Roberval's mechanism via a rotary securing table 27 and a rotary axis 20, the free end is deviated downward according to the weight. The Roberval's mechanism is vibrated by the shock at the loading of the object to be heated 28 or by the shock for the Roberval's mechanism applied later from outside, the vibration is generated by the peculiar vibration frequency according to the measured weight. By the generated vibration, an induced voltage is generated between a magnet 18 fixed on the free end and a coil 19 fixed on the fixed end. By detecting the voltage, the whole weight can be measured. By controlling the oscillation of a magnetron according to the weight of the object to be heated 28, the heating cooking can be performed by the optimum heating output and heating time. |
