Wegen der bei Hochspannungserzeugung erforderlichen Isolotion und sonstigen Sicherheitsgründen benötigen die Geräte einen gewissen Platz und sind nicht Uberall, insbesondere nicht in feuchter Luft, unterzubringen. Durch die erfindungsgemäße Lösung jedoch wird es möglich, den Generator außerhalb der Verkaufstheke an einem geeigneten Ort anzuordnen, von dem aus die erforderliche Hochspannung den eigentlichen lonisierungselementen zugeführt werden kann.In these known devices, however, for security reasons, the Electrode arrangement directly with the high voltage generator to form a unit connected and installed at a point in the room that removed is from people and from equipment that people handle. Because of the Isolotion required for high voltage generation and other safety reasons the devices require a certain space and are not everywhere, especially not in humid air. However, by the solution according to the invention it is possible to arrange the generator in a suitable place outside the sales counter, from which the required high voltage supplies the actual ionization elements can be fed.

Bei einer Ausführungsform der Erfindung ist vorgesehen, daß die Elektrodenanordnung durch eine oder mehrere Ionisationsröhren gebildet ist. Diese Röhren können besonders leicht, getrennt von der eigentlichen Hochspannungserzeugung, in dem knappen Raum innerhalb einer Verkaufstheke platzsparend untergebracht werden.In one embodiment of the invention it is provided that the electrode arrangement is formed by one or more ionization tubes. These tubes can be special easily, separated from the actual high voltage generation, in the tight space be accommodated within a sales counter to save space.

Im Rahmen der Erfindung empfiehlt es sich, die die Ionisation der Luft bewirkende Elektrodenanordnung im Luftkanal anzuordnen. Dies erweist sich aus optischen, Sicherheits- und PlatzgrUnden als vorteilhaft. Um sie in unmittelbare Ndhe iur Ware und damit zur bestmöglichen Wirkung zu bringen, schlägt die Erfindung vor, daß die Elektrodenanordnung im Bereich des Luftaustritts aus dem Kanal angeordnet ist, also möglichst kurz hinter den Luftaustrittsschlitzen, wo die Luft unmittelbar anschließend auf die Ware Ubertritt.In the context of the invention, it is recommended that the ionization of the To arrange air-causing electrode arrangement in the air duct. This turns out to be optical, security and space reasons as advantageous. To them in immediate The invention proposes to bring the goods and thus to the best possible effect before that the electrode arrangement is arranged in the region of the air outlet from the duct is, so as close as possible behind the air outlet slots, where the air is immediately then transfers to the goods.

In Weiterbildung der Erfindung ist vorgesehen, daß die Ionisierungsspannung der Elektrodenanordnung rqplbar ist, um je nach Bedarf eine schwtlchere oder stärkere Ionisation zu erreichen. Insbesondere empfiehlt es sich hierbei, daß bei Unterteilung der Theke in mehrere benachbarte Zonen fUr jede Zone eine Elektrodenanordnung vorgesehen ist, so daß eine separate Regelung der einzelnen Zonen möglich wird.In a further development of the invention it is provided that the ionization voltage the electrode arrangement can be adjusted to a weaker or stronger one as required To achieve ionization. In particular, it is recommended that when subdividing the counter in several adjacent zones for each zone an electrode arrangement is provided so that separate regulation of the individual zones is possible.

Zusätzlich können fUr die einzelnen Zonen unterschiedlich große Ionisationsröhren vorgesehen sein, um eine individuelle Entkeimung je nach Warenart zu erreichen.In addition, different sizes can be used for the individual zones Ionization tubes be provided in order to achieve individual sterilization depending on the type of goods.

In der Zeichnung ist die Erfindung schematisch am Beispiel eines Schnittes durch eine der üblichen Verkaufstheken dargestellt.
