PURPOSE:To prevent uneven temperature workmanship of a material to be heated from occurring, by so constituting that output of a high frequency generator is controlled according to the outputs of a gas sensor and a weight sensor. CONSTITUTION:Weight of hood 9 detected by a pressure sensor type weight sensor 10 by making use of piezo effect is applied to a microcomputer 6 through a detecting circuit 11. On the other hand, gas density within a cooking room 1 detected by a gas sensor 4 is applied to the microcomputer 6 through a gas concentration detecting circuit 5. The gas concentration is corrected by the computer 6 according to weight 11, and output of a magnetron 3 is controlled by the corrected gas concentration. Then, temperature workmanship can be made even by controlling a high frequency generator 3 through correction by weight of generating gas concentration of a material to be heated. |
