Claims

[Scope of utility model registration request]

A heating chamber 3 that stores an object to be heated 6, a high frequency oscillator 1 that supplies high frequency energy into this heating chamber, and a part of the high frequency energy from this high frequency oscillator that corresponds to temperature changes in dielectric loss of the object to be heated. - In a high frequency heating device that controls the oscillation of a high frequency oscillator by the signal taken out from the receiving antenna, the receiving antenna is embedded inside a saucer 5 made of a dielectric material on which an object to be heated is placed. , a metal tube 8c whose one end 7a protrudes outside the saucer and is fixed to the outer wall of the heating chamber 3.
A high-frequency antenna is connected to one tapered hole 8b of an attenuator 8 consisting of an attenuator 8 so as to be freely connected to and detachable from the attenuator 8, and a signal taken out by the receiving antenna is radiated into the attenuator 8 and taken out as a received signal to the outside of the heating chamber. heating device.
