HIGH-FREQUENCY HEATING APPARATUS

摘要

A high-frequency heating apparatus, in which the high-frequency energy is uniformly distributed in a heating chamber for effectively heating the matter in the heating chamber. An energy distribution modifying means is provided in conformity to the shape of the heating chamber and on at least one of coaxial inner and outer conductors defining a cylindrical passage, which communicates with a waveguide coupled to a high-frequency oscillator. The high-frequency energy from the high-frequency oscillator is guided through the waveguide and the cylindrical passage to enter the heating chamber and is uniformly distributed in the heating chamber through the energy distribution modifying means.
