HIGH FREQUENCY HEATING UNIT WITH ROTATING WAVEGUIDE |
摘要 |
<p>This invention is designed to make uniform the heating of the object inside the heating chamber by turning an internal waveguide which is roughly in a foldable fan shape and located at the bottom of the heating chamber in a structure adapted for feeding high frequency electric waves from the bottom of the heating chamber. In order to have stable gyration of the internal waveguide, and annular protrusion made of a low loss dielectric is placed between the low impedance parts provided on the internal waveguide and the heating chamber bottom surface. In this way, a rotary structure which is economical, easy to assemble and reliable can be realized.</p> |
