Abstract
PURPOSE: To detect a loadless baking state rapidly and to prevent damage on a high-frequency oscillator by a method wherein a metal plate is arranged in parallel with the inside wall surface of a heating chamber, and a temperature detecting element is arranged on the outside wall surface of the heating chamber in register with the metal plate.
CONSTITUTION: In a high-frequency heater comprising a high-frequency oscillator 4 connected with a heating chamber 1 through a waveguide 5, a metal plate 7 is fitted to the inside wall surface of the heating chamber 1 in parallel with the wall surface by screws 9 or the like, and a temperature detecting elements 8 for detecting the temperature of the wall surface 1a of the heating chamber 1 is arranged in register with the metal plate 7, thereby forming a symmetric micro-wave strip line between the metal plate 7 and the wall surface 1a. When the high-frequency heater is in a loadless baking condition, high-frequency electric and magnetic fields are generated between the metal plate 7 and the wall surface 1a, a high-frequency current flows in the plate 7 and the surface 1a, and the wall surface 1a is heated to an abnormally high temperature. This temperature rise is detected by the temperature detector 8, and the oscillator 4 is stopped.
