  • Constitution Of High-Frequency Heating (AREA)

Abstract

PURPOSE: To prevent elctric-wave leakage without necessitating ferrite rubber by arranging metal or dielectrics having a high dielectric constant in a proper cycle constitution in the groove part of a door and constituting a delaying line having a phase velocity smaller than the velocity of light in the longitudinal direction of the groove.
CONSTITUTION: A door part consisting of front door plate 1 and rear door plate 2 which are arranged opposed to an oven flange 3 is equipped with a groove 8 which has an opening opposed to said flange 3. The opening part of the groove 8 has a width 12 smaller than the width 13 of the wall surface of a heating chamber, and the elctric-wave passage 19 in parallel flat board line is formed. The groove 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/2, is installed in the longitudianl direction of the groove 8, keeping a distance 17 less than about λ/12.
