HIGH-FREQUENCY HEATING APPARATUS

摘要

This invention relates to a high-frequency heating apparatus comprising a high-frequency oscillator, a heating chamber, an antenna, a dielectric plate, a detector and a control circuit. The oscillator generates electromagnetic waves and supplies them to the heating chamber. The antenna, which is located outside of the heating chamber, is used to receive the transmitted waves. The dielectric plate covers an opening in the chamber in front of the antenna. The detector receives the signal from the antenna and provides a signal to the control circuit that will eventually control the power of the oscillator to provide a stable heating process.
