(JA) 高周波加熱装置
Abstract: front page image
(EN)The objective of the present invention is to obtain a high-frequency heating device that is capable of propagating high-frequency waves, which have been oscillated by a high-frequency oscillator, into a heating chamber more evenly. An antenna (20) of the high-frequency heating device is equipped with: slot antennas (31, 32) that utilize slit apertures (31b, 32b), which are created on conductor sections (31a, 32a) connected to an antenna shaft (22), as first radiating sections (30); conduction paths (42, 43) that are bifurcated from the first radiating sections (30); and a second antenna that utilizes an antenna plate (41), which is connected to the conduction paths (42, 43), as a second radiating section (40).
(FR)La présente invention vise à proposer un dispositif de chauffage à haute fréquence qui est apte à propager plus régulièrement dans une enceinte de chauffage des ondes à haute fréquence qui ont été produites par un oscillateur à haute fréquence. Une antenne (20) du dispositif de chauffage à haute fréquence comprend : des antennes à fentes (31, 32) qui utilisent, comme premières sections rayonnantes (30), des ouvertures en forme de fente (31b, 32b) qui sont créées dans des sections de conducteur (31a, 32a) connectées à une tige d'antenne (22) ; des trajets de conduction (42, 43) qui bifurquent par rapport aux premières sections rayonnantes (30) ; et une seconde antenne qui utilise, comme seconde section rayonnante (40), une plaque d'antenne (41) qui est connectée aux trajets de conduction (42, 43).
(JA) 高周波発振器から発振される高周波をより均等に加熱室内に伝播させることのできる高周波加熱装置を得る。 高周波加熱装置のアンテナ20は、アンテナシャフト22に連結された導体部31a、32aに形成されたスリット穴31b、32bを第一放射部30とするスロットアンテナ31、32と、第一放射部30から2分岐された導電経路42、43と、導電経路42、43に接続されたアンテナ平板41を第二放射部40とする第二アンテナとを備えた。
