Abstract

1. An electrostatic high-voltage electrode for ionizing the air, having a multiplicity of needle-shaped individual electrodes (9) which are arranged in a plurality of like rows (6, 7, 8) and which each have a point (10), all the individual electrodes (9) being alike in construction and extending parallel to one another and their points (10) lying in one plane, and furthermore the individual electrodes (9) have a distance apart which is at least equal to half their free length (13), characterized in that the free length (13) of the individual electrodes (9) is in the ratio of at least 50:1 to their diameter, and that situated opposite the individual electrodes in the one row are the gaps between the individual electrodes of the adjacent rows.

Description

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

Elektroden, insbesondere zur Ionisierung der Luft sind in einer Vielzahl von Ausführungsformen bekannt (DE-A-2 650 259).Electrodes, in particular for ionizing the air, are known in a large number of embodiments (DE-A-2 650 259).

Es ist ferber eine gattungsgemäße Hochspannungselektrode gemäß dem Oberbegriff des Hauptanspruches bekannt (DE-A-00 143 171 Der bekannten Elektrode haftet aber der Nachteil an, daß im Betrieb Ozon erzeugt wird, was in hohem Maße unerwünscht ist.It is also known a generic high voltage electrode according to the preamble of the main claim (DE-A-00 143 171 but the known electrode has the disadvantage that ozone is generated during operation, which is highly undesirable.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine gattungsgemäße Hochspannungselektrode so weiterzubilden, daß im Betrieb mögichst wenig Ozon gebildet wird.The invention is therefore based on the object of developing a generic high-voltage electrode so that as little ozone as possible is formed during operation.

Diese Aufgabe wird bei einer gattungsgemäßen Hochspannungselektrode gemäß dem Oberbegriff des Hauptanspruches erfindungsgemäß durch dessen kennzeichnende Merkmale in überraschend einfache Weise gelöst.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.

Durch die Einzelelektroden, die eine große Längserstreckung haben und in einer bestimmten Pakkungsdichte unvergossen in der Atmosphäre angeordnet werden, wird, was nicht zu erwarten war, kein Ozon erzeugt, wenn keine sonstigen Spitzen, Grate oder sonstigen Unebenheiten vorhanden sind.Due to the individual electrodes, which have a large longitudinal extension and are arranged in a potting density in the atmosphere without casting, what was not to be expected, no ozone is generated if there are no other peaks, burrs or other bumps.

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 Bezugsnahme auf die Zeichnung näher erläutert. In dieser zeigt:

  • Fig. 1 eine Hochspannungselektrode gemäß der Erfindung, in perspektivischer Darstellung;
  • Fig. 2 eine Draufsicht 11-11 gemäß Figur 1 und
  • Fig. 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;
  • Fig. 2 is a plan view 11-11 of Figure 1 and
  • 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 Längserstreckung 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 Reihe 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 11, with soldering points 12 for the individual electrodes 9, to which these are firmly soldered. All electrodes in a row and the row one below the other are connected to a negative high-voltage source (not shown).

Die freie Länge 13 der Einzelelektrode 9 (Fig. 3), die sich über die Printplatte 8 ersteckt, 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 hervostehen.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 at least half their length apart, preferably two thirds of them spaced apart, as can be seen schematically in FIG. 2, which protrude perpendicularly over the long side 13 of the overall rectangular plates 6, 7, 8, namely perpendicularly over the long side 13.
