High-frequency heating apparatus. |
摘要 |
<p>A high-frequency heating apparatus (K) comprising: a high-frequency oscillator (1) for oscillating high-frequency electromagnetic wave by electric power supplied from a power source circuit (11); a heating chamber (3) into which the high-frequency electromagnetic wave is supplied by the high-frequency oscillator (1); an antenna (7) which is provided outside the heating chamber (3) and adjacent to an opening (6) of the heating chamber (3); a dielectric plate (5) for covering the opening (6), which is provided in the heating chamber (3) so as to confront the antenna (7) through the opening (6); a detector (8) which receives an output from the antenna (7) and has a grounded portion (15, 16) such that the grounded portion (15, 16) is connected to the heating chamber (3); and a control circuit (10) which receives an output from the detector (8) so as to output a control signal to the power source circuit (11). <IMAGE></p> |
