Description

Die Erfindung betrifft eine elektrostatische Hochspannungselektrode gemäß dem Oberbegriff des Hauptanspruchs.The invention relates to an electrostatic high-voltage electrode according to the preamble of the main claim.

Elektroden dieser Gattung, insbesondere zur Ionsisierung der Luft sind in einer Vielzahl von Ausführungsformen bekannt.Electrodes of this type, in particular for ionizing the air, are known in a large number of embodiments.

Allen bekannten Elektroden haftet aber der Nachteil an, daß im Betrieb Ozon erzeugt wird, was im hohem Maße unerwünscht ist.However, all known electrodes have the disadvantage that ozone is generated during operation, which is highly undesirable.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Hochspannungselektrode so auszubilden, daß im Betrieb möglichst wenig Ozon gebildet wird.The invention has for its object to design a generic high voltage electrode so that as little ozone is formed during operation.

Diese Aufgabe wird bei einer gattungsgemäßen Hochspannungselektrode gemäß dem Oberbegriff des Hauptanspruchs erfindungsgemäß durch dessen kennzeichnende Merkmale in überraschend einfacher Weise dadurch gelöst, daß die Einzelelektroden eine große Längserstreckung haben und in einer bestimmten Packungsdichte unvergossen in der Atmosphäre angeordnet werden, wobei keine sonstigen Spitzen, Grate oder sonstige Unebenheiten vorhanden sind.This object is achieved in a generic high-voltage electrode according to the preamble of the main claim according to the invention by its characterizing features in a surprisingly simple manner in that the individual electrodes have a large longitudinal extent and are arranged in a certain packing density without casting in the atmosphere, with no other peaks, burrs or other bumps are present.

Zweckmäßige Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Expedient refinements and developments of the invention are characterized in the subclaims.

Ein bevorzugtes Ausführungsbeispiel wird nachfolgend unter Bezugnahme auf die Zeichnung näher erläutert. In dieser zeigt:

  • Figur 1 eine Hochspannungselektrode gemäß der Erfindung, in perspektivischer Darstellung;
  • Figur 2 eine Draufsicht II-II gemäß Figur 1 und
  • Figur 3 eine Seitenansicht III-III gemäß Figur 1.
A preferred embodiment is explained in more detail below with reference to the drawing. In this shows:
  • 1 shows a high-voltage electrode according to the invention, in a perspective view;
  • Figure 2 is a plan view II-II of Figure 1 and
  • FIG. 3 shows a side view III-III according to FIG. 1.

Die insgesamt mit 5 bezeichnete, elektrostatische Hochspannungselektrode zur Ionisierung der Luft weist in drei Reihen 6, 7, 8, die parallel zueinander verlaufen und als Printplatten ausgebildet sind, je eine Reihe zueinander parallel verlaufender Einzelelektroden 9 mit einer sehr scharfen Spitze 10 auf. Die Spitzen 10 liegen alle in einer Ebene, die senkrecht zur Längserstrekkung der Einzelelektroden 9 verläuft. Hierbei liegen den Elektroden 9 in der einen Reihe 6 die Zwischenräume zwischen den Elektroden der benachbarten Reihe 7 - und umgekehrt - gegenüber. Die Printplatten 6, 7, 8 weisen eine schematisch mit 11 bezeichnete gedruckte Schaltung mit Lötpunkten 12 für die Einzelelektroden 9 auf, an denen diese festgelötet sind. Alle Elektroden einer Reihe und die Reihen untereinander sind an eine - nicht gezeigte - negative Hochspannungsquelle angeschlossen.The electrostatic high-voltage electrode for ionizing the air, designated overall by 5, has three rows 6, 7, 8, which run parallel to one another and are designed as printed circuit boards, each with a row of individual electrodes 9 running parallel to one another with a very sharp tip 10. The tips 10 all lie in a plane that runs perpendicular to the longitudinal extent of the individual electrodes 9. Here, the electrodes 9 in one row 6 are opposite the spaces between the electrodes of the adjacent row 7 - and vice versa. The printed circuit boards 6, 7, 8 have a printed circuit, schematically designated by 11, with soldering points 12 for the individual electrodes 9, to which these are firmly soldered. All electrodes in a row and the rows one below the other are connected to a negative high-voltage source (not shown).

Die freie Länge 13 der Einzelelektrode 9 (Figur 3 ), die sich über die Printplatte 8 erstreckt, verhält sich zum Durchmesser der Einzelelektroden mindestens wie 50:1. Ferner sind die Einzelelektroden 9 mindestens im Abstand ihrer halben Länge, vorzugsweise zwei Dritteln davon voneinander beabstandet angeordnet, wie schematisch in Figur 2 ersichtlich, die die senkrecht über die Längsseite 13 der insgesamt rechteckförmigen Platten 6, 7, 8, und zwar senkrecht über der Langseite 13 hervorstehen.The free length 13 of the individual electrode 9 (FIG. 3), which extends over the printed circuit board 8, is at least 50: 1 in relation to the diameter of the individual electrodes. Furthermore, the individual electrodes 9 are arranged at least at a distance of half their length, preferably two thirds, from each other, as shown schematically in FIG. 2, which are perpendicular to the long side 13 of the rectangular plates 6, 7, 8 and perpendicular to the long side 13 protrude.
