Description
Gegenstand der Hauptpatentanmeldung D 26085 VIIId/21h ist eine Einrichtung zur Erzeugung einer definierten primären Feldverteilung in einem Hohlraum, in welchen durch Schlitze in einer Wand aus einem Zuführungshohlleiter Mikrowellenenergie eingekoppelt wird, dadurch gekennzeichnet, daß der Zuführungshohlleiter sich über mindestens eine volle Wandfläche des Arbeitsraumes erstreckt, wobei die Schlitze, welche durch Größe, Form und Anordnung die gewünschte definierte Feldverteilung bewirken, ebenfalls über die ganze Fläche verteilt sind, die Hohlleiter und Arbeitsraum voneinander trennt.The subject of the main patent application D 26085 VIIId / 21h is a device for generating a defined primary field distribution in a cavity, in which through slots in a wall Microwave energy is coupled into a feed waveguide, characterized in that the feed waveguide extends over at least one full wall surface of the work space, wherein the Slots which, through their size, shape and arrangement, produce the desired, defined field distribution, are also distributed over the entire area, which separates the waveguide and the work space.
Es hat sich ergeben, daß erfindungsgemäß diese Feldverteilung noch verbessert werden kann, wenn die die Schlitze tragende AVand des Zuleitungshohlraumes an ihren vier Kanten so verkürzt wird, daß entlang den senkrecht zu ihr stehenden Wänden lange Schlitze entstehen.It has been found that, according to the invention, this field distribution can be improved if the AVand of the supply cavity carrying the slots is shortened at its four edges so that Long slits are created along the walls perpendicular to it.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung, und zwar einen Mikrowellen-Kochraum, der inThe drawing shows an embodiment of the invention, namely a microwave cooking space, the in
Fig. 1 im Querschnitt, inFig. 1 in cross section, in
Fig. 2 im Schnitt längs der Linie I-T der Fig. 1 dargestellt ist.Fig. 2 is shown in section along the line I-T of FIG.
Um die Feldstärke in der Nähe der senkrechten Begrenzungswände 3 des Arbeitsraumes 1 anzuheben, wird erfindungsgemäß die Trennwand 4 zwischen Zuleitungshohlraum 5 und Arbeitsraum 1 nicht bis zu diesen senkrechten Begrenzungswänden durchgeführt, sondern verkürzt, so daß ein offener Streifen 12 entsteht. Mit 2 ist das im Arbeitsraum befindliche Kochgut bezeichnet. In order to increase the field strength in the vicinity of the vertical boundary walls 3 of the workspace 1, according to the invention, the partition 4 between the supply cavity 5 and working space 1 is not up to These vertical boundary walls carried out, but shortened, so that an open strip 12 is formed. The item to be cooked in the working area is designated with 2.
Bei gleichmäßiger Breite des offenen Streifens würde an den Stirnseiten 13 die Ausstrahlung zu stark werden. Die Streifen sind daher hier verschmälert und vorzugsweise mit einer kapazitiven Beschwerung 14 versehen, und zwar z. B. mit einer Abwinkelung mindestens an der Einkoppelseite, mit deren Größe die Feldstärkenverteilung eingestellt wird.With a uniform width of the open stripe, the radiation on the end faces 13 would be closed get strong. The strips are therefore narrowed here and preferably with a capacitive weighting 14 provided, namely, for. B. with a bend at least on the coupling side, with whose size the field strength distribution is set.
