  • Constitution Of High-Frequency Heating (AREA)

Abstract

PURPOSE: To prevent electric-wave leakage effectively by arranging metal or dielectrics having a high dielectric constant in a proper cycle constitution in the groove part of an oven range and constituting a delaying line having a phase velocity smaller than the velocity of light in the longitudinal direction of the groove.
CONSTITUTION: An oven flange 3 is equipped with a groove 40 having an opening opposed to the door part consisting of a front door plate 1 and a rear door plate 2. The width 12 of the opening part of said groove 40 is set smaller than the width of the wall surface of a heating chamber, and the electric-wave passage 19 in parallel flat board line is formed. The groove 40 is protected with a choke cover 9 made of dielectrics, and a wave-shaped metal plate 10 is installed in the groove. The metal plate 10 having a width 14 larger than about λ(wave length)/30 of the electric wave in use and a bending length 15 less than about λ/12, is installed in the longitudinal direction of the groove 40, keeping the distance 11 less than about λ/2 between the metal plate 10 and the outside wall of the groove part 40.
