<p>PROBLEM TO BE SOLVED: To uniformly heat two kinds of foods with suitable temperatures, which are different from each other, and to heat even one food efficiently. SOLUTION: A rotating antenna 7, formed by arranging three sheets of long conductor pieces 7a, 7b, 7c are arranged radially with the same angle each other, on a center conductor 8 which is located inside a high-frequency supply chamber 3 and arranging other three sheets of short conductor pieces 7d, 7e, 7f, which are shorter than the three sheets of long conductor pieces 7a, 7b, 7c, arranged radially on the center conductor 8, is installed, the rotating antenna 7 is temporarily halted or decelerated by a drive part 9 when the short conductor pieces 7d, 7e, 7f locate at a magnetron 4 side.</p> |
