und ohne Unterbrechung der Funktion des Geruchverschlusses statt.
Sie erfolgt mittels einer für Geruchverschlüsse neuartigen Kombination von
elektromechanischer Schwingung, von Schwingungen niederer Frequenz bis zu
Ultraschallbeschallung, Erhitzung des Geruchverschlußinnenraumes und der
Sperrflüssigkeit und Verhinderung von Innenwandbewuchs durch eine
bewuchsabweisende und antimikrobiell wirksame Beschichtung.The invention describes an arrangement for the automatic cleaning and disinfection of odor traps in sewers. Cleaning and disinfection take place automatically during the intended use and without interrupting the function of the odor trap.

Die Gefahr der Rückverkeimung von sanitären Apparaturen und Einrichtungen
und damit auch der Raumluft durch Mikroorganismen aus Abwasserrohrleitungen
ist besonders im klinischen Bereich seit längerem bekannt und
gefürchtet, stellt jedoch ein generelles hygienisches Problem in Bereichen
gemeinschaftlicher Nutzung sanitärer Einrichtungen dar.
Abwasserrohrleitungen mit Zonen geringer oder stark schwankender Durchströmungsgeschwindigkeit
wie beispielsweise dann integrierte Geruchverschlüsse,
in denen Abwasser gleichzeitig als Geruchverschlußmedium dienen,
sind bekanntermaßen Aufenthalts - und Vermehrungsstätten von Mikroorganismen.
In Geruchverschlüssen herrschen zeitweise optimale Voraussetzungen für
das Überleben und die Vermehrung von gesundheitsgefährdenden Keimen. The danger of re-entrainment of sanitary appliances and facilities and thus the indoor air by microorganisms from sewage pipelines has long been known and feared particularly in the clinical field, but represents a general hygienic problem in areas of community use sanitary facilities.
Wastewater pipelines with zones of low or highly fluctuating flow rate, such as, for example, integrated odor traps, in which wastewater simultaneously serves as a trap medium, are known to be habitats and propagation sites of microorganisms. In odor occlusions there are at times optimal conditions for the survival and reproduction of harmful germs.
Die Rückverkeimung von Sanitäreinrichtungen (beispielsweise Waschbecken)
und der Raumluft geschieht auf folgende Weise:
Es sind Entwicklungen für Abwasserleitungen und Sifone beschrieben, welche
sich der keimtötenden Eigenschaften von hoher Temperatur (DE 4206901, US
41 92 988 und GB 1 417 711), ultravioletter Strahlung in Flüssigkeiten (DE 4206901, DE 4025078
A1, DE 29509210 U1) bedienen. Auch Entwicklungen zur Reinigung und
Entkeimung von Sifonen und Rohrleitungen mittels Ultraschall sind bekannt
(DE 27 47 992 A1, US 31 75 567).
Die Kombinationen von ultraviolettem Licht und Ultraschall (DE 295 09 210 U1)
wird für die Reinigung und Entkeimung von Rohrleitungen und Sifonen nicht,
jedoch für die Reinigung und Desinfektion von Gegenständen in Flüssigkeiten
beschrieben. Die Kombination von ultraviolettem Licht und hoher Temperatur
(DE 42 06 901 A1) wird für die Behandlung der Flüssigkeit in einem Sifon
beschrieben.
Die Kombination der Wirkung von elektromechnischen Schwingungen,
insbesondere Ultraschall mit erhöhter Temperatur wurde für Geruchverschlüsse
bisher nicht beschrieben
Alle bekannten Erfindungen berucksichtigen Teilaspekte des Gesamtgeschehens
in einer Rohrleitung oder einem Sifon und bieten dafür Lösungen
an.There are described developments for sewage pipes and sifons, which use the germicidal properties of high temperature (DE 4206901, US 41 92 988 and
The combination of ultraviolet light and ultrasound (DE 295 09 210 U1) is not described for the cleaning and sterilization of piping and siphons, but for the cleaning and disinfection of objects in liquids. The combination of ultraviolet light and high temperature (DE 42 06 901 A1) is described for the treatment of the liquid in a sifon.
The combination of the effect of electromechanical vibrations, in particular ultrasound with elevated temperature has not been described for odor traps
All known inventions take into account partial aspects of the overall situation in a pipeline or a siphon and offer solutions for this.
In der Praxis haben diese Teillösungen derartige Nachteile, daß bisher keine der Lösungen praktische Einführung in die Klinik gefunden haben, obschon viele Anwendungsuntersuchungen mit diesen Systemen, zum Teil auch über längere Zeiträume, durchgeführt wurden. In practice, these partial solutions have such disadvantages that so far none of Solutions have found practical introduction to the clinic, albeit many Application studies with these systems, sometimes over longer ones Periods were carried out.
Die alleinige Anwendung hoher Temperaturen über lange Zeiträume führt
infolge der verdampfungsbedingten Eintrocknung von Schmutzwasser zu
verstärkten Belegungen der Innenwände von Rohrleitungen und Sifonen.
Die Geruchverschlüsse verstopfen und verlieren ihre Funktion. Im Vorfeld wird
der eingetrocknete Wandbelag wechselweise durch nachströmendes Wasser
wiederbefeuchtet und stellt eine sehr gute Rückverkeimungsbahn dar. Darüber
hinaus können hohe Verdunstungsverluste und Verkrustungen die Funktion des
Geruchverschlusses unterbinden oder die Rohrleitung verstopfen. Die Abtötung
pathogener Keime ist jedoch erst bei Temperaturen gewährleistet, welche
wesentlich die Verdunstung der Flüssigkeit und damit die Wandbelegung
fördern.
Die Effizienz der Anwendung von ultraviolettem Licht in Flüssigkeiten hängt sehr
stark vom Verschmutzungsgrad des Abwassers und der dadurch bedingten
Durchdringung (Transmission) ab. Zudem sind einige, vor allem pathogene
Keime wie beispielsweise Legionellen mit UV - Bestrahlung allein nicht zu
erreichen oder nur schwer abzutöten.
Die Einwirkung von hoher Temperatur und ultraviolettem Licht kann
insbesondere bei stark verschmutzten und ggf. infektiösen Flüssigkeiten, wie sie
üblicherweise in der klinischen Praxis auftreten, aufgrund geringer
Durchdringungsfähigkeit zu keiner befriedigenen Keimabtötung führen und auch
nicht den Wandbewuchs und damit die Rückverkeimung über diesen Weg
verhindern. Die Wirksamkeit von Ultraschall auf die Abtötung von Keimen ist
temperaturabhängig. Da die Temperatur der Flüssigkeit in Rohrleitungen und
Geruchverschlüssen von vielen Faktoren abhängig und daher schwankend ist,
ist der Abtötungseffekt durch Ultraschall allein ebenfalls schwankend und daher
auch bei maximaler Beschallung nicht vollständig definierbar. The sole use of high temperatures over long periods leads due to the evaporation-related drying of dirty water to increased occupancies of the inner walls of pipes and siphons.
The odor locks clog and lose their function. In advance, the dried wall covering is alternately rewetted by inflowing water and represents a very good Rückverkeimungsbahn. In addition, high evaporation losses and encrustations can prevent the function of the odor trap or block the pipe. However, the killing of pathogenic germs is only guaranteed at temperatures which substantially promote the evaporation of the liquid and thus the wall occupancy.
The efficiency of the application of ultraviolet light in liquids depends very much on the degree of pollution of the wastewater and the resulting penetration (transmission). In addition, some, especially pathogenic germs such as Legionellae with UV irradiation alone are not attainable or difficult to kill.
The effect of high temperature and ultraviolet light, especially in heavily contaminated and possibly infectious fluids, as they usually occur in clinical practice, due to low permeability to no satisfactory germ killers and prevent wall walling and thus the Rückverkeimung this way. The effectiveness of ultrasound on the killing of germs is temperature dependent. Since the temperature of the liquid in pipes and odor traps depends on many factors and therefore fluctuates, the killing effect by ultrasound alone is also fluctuating and therefore not fully definable even at maximum sonication.
Bei Raumtemperatur beispielsweise ist der Abtötungseffekt bei sinnvoll
installierbaren Ultraschall - Leistungen (beispielsweise 300 - 1000 Watt/Liter)
nur bei relativ langen Beschallungszeiten (eine Stunde und länger) möglich,
während bei Temperaturen von 50°C bereits wenige Minuten ausreichend sind.
Bei dieser Temperatur erfolgt noch keine Abtötung von Mikroorganismen durch
die Wärme allein.
In der Praxis ist es zudem notwendig, die Beschallung in Intervallen durchzuführen
und dabei die Beschallungszeit so kurz wie möglich zu halten.
Andererseits fordern Wirtschaftlichkeit und Geräuschpegel die Installation von
möglichst geringen Ultraschall - Intensitäten.
Die intervallartige Beschallung des Innenraumes des Geruchverschlusses führt
besonders bei hoheren Temperaturen zur Ablösung vorhandener Wandbeläge
und verhindert gleichzeitig eine Neubelegung.At room temperature, for example, the killing effect at sensibly installable ultrasonic powers (for example 300-1000 watts / liter) is only possible with relatively long sonication times (one hour and longer), while at temperatures of 50 ° C only a few minutes are sufficient. At this temperature, no killing of microorganisms takes place by the heat alone.
In practice, it is also necessary to perform the sonication at intervals while keeping the sonication time as short as possible.
On the other hand, efficiency and noise levels require the installation of the lowest possible ultrasound intensities.
The interval-like sonication of the interior of the odor trap leads to the replacement of existing wall coverings, especially at higher temperatures, and at the same time prevents a new occupancy.
Die Aufgabe der nachfolgend zu beschreibenden Erfindung ist es, einen selbstdesinfizierenden Geruchverschluß zu beschreiben, welcher das Problem der Vermehrung und des Austritts von Mikroorganismen aus Abwasserrohrleitungen mit durch den derzeitigen Stand der Technik nicht darstellbarer Sicherheit und Reproduzierbarkeit durch maximale und stets reproduzierbare Keimabtötung löst, den Bewuchs der innenwände von Geruchverschlüssen und den Austntt von mit lebenden Keimen kontaminierten Aerosolen aus Rohrleitungen verhindert und dabei die vorstehend genannten Nachteile bekannter Entwicklungen nicht aufweist.

Temperaturregelung über einen Thermostatteil notwendig ist, weil die für die
Entkeimung notwendige Temperatur üblicherweise nicht oder zeitlich nur so
begrenzt überschritten wird, so daß wesentliche Verdunstungsverluste nicht
entstehen können. Heiz - und Ultraschallsystem werden zeitversetzt geschaltet.
Zunächst wird das Heizsystem eingeschaltet. Bei Erreichen der Zeit, die für das
Erreichen der Entkeimungstemperatur notwendig ist, schaltet sich die Heizung
ab und der Ultraschall ein. Die Entkeimungstemperatur wird durch die
Auslegung der Heizung nach einer bestimmten, experimentell ermittelten Zeit
erreicht. Zu diesem Zeitpunkt wird die Heizung abgeschaltet und der Ultraschall
eingeschaltetThe apparatus is functional in the following version with minimal equipment.
It is only so much heating power installed on the

zeitversetzt geschaltet Beispiel: Heizung ein für 4 x 3 Stunden pro 24 Stunden.
Beschallung unabhänging von der Heizung aller 2 Stunden jeweils 10 Minuten.
Diese Ausführungsvariante ist mit einer antimikrobiellen Innenbeschichtung
versehen.It is only so much heating power installed on the
This variant is provided with an antimicrobial inner coating.
Ausführungsbeispiel 5 ist ein selbstdesinfizierender Geruchverschluß in der
Form eines gebräuchlichen Flaschensifons in minimaler Instrumentierung mit
Ultraschall, Heizung und Wärmeisolation
In dieser Ausführungsvariante wird die installierte Heizleistung so gewählt,
daß die Sperrflüssigkeit entweder sehr schnell (höhere Heizleistung) oder
langsam (geringe Heizleistung) erhitzt wird
Im Falle der Installation einer niedrigen Heizleistung (ca.0,1 - 0,3 Watt / ml)
wird von einer Minimaltemperatur der Sperrflüssigkeit zum Beginn der
Heizung ausgegangen. Die Temperatur, welche für die Ultrabeschallung
notwendig ist, wird nach langerer Zeit (30 - 60 Minuten) erreicht. Zu diesem
Zeitpunkt wird dann der Ultraschall zugeschaltet.
In this embodiment, the installed heating power is selected so that the barrier liquid is heated either very quickly (higher heat output) or slow (low heat output)
In case of installation of a low heat output (ca.0,1 - 0,3 watt / ml), a minimum temperature of the barrier liquid at the beginning of the heating is assumed. The temperature necessary for the sonication is reached after a long time (30-60 minutes). At this time, the ultrasound is then switched on.
Diese Anordnung ist für haufig und regelmäßig benutzte Abflüsse, in die Flüssigkeiten mit hoheren Keimgehalten und geringeren Temperaturen eingebracht werden, vorteilhaft. This arrangement is for frequent and regularly used drains into the Liquids with higher germ contents and lower temperatures be introduced, advantageous.
Im Falle der Installation einer hohen Heizleistung (ca.1 - 3 Watt / ml
Sperrflüssigkeit) erreicht die Sperrflüssigkeit unabhängig von der Ausgangstemperatur
innerhalb weniger Minuten Temperaturen in der Nähe des Siedepunktes
der Sperrflüssigkeit. Diese Temperatur wird während der Zeit der
Ultrabeschallung, die dann sehr kurz sein kann, aufrecht erhalten. Heizung
und Ultraschall werden gleichzeitig an - und ausgeschaltet.
Mit dieser Anordnung werden besonders hartnäckige Sporenbildner in
kürzester Zeit abgetötet. Fur nicht sporenbildende Bakterien sowie Hefen
und Pilze ist nur eine sehr kurze Beschallungszeit notwendigIn the case of the installation of a high heat output (approx. 1 - 3 watt / ml barrier liquid), the barrier liquid will reach temperatures close to the boiling point of the barrier liquid within a few minutes, regardless of the outlet temperature. This temperature is maintained during the time of the sonication, which may then be very short. Heating and ultrasound are switched on and off at the same time.
With this arrangement, particularly stubborn spore formers are killed in no time. For non-sporulating bacteria as well as yeasts and fungi only a very short sonication time is necessary
Ausführungsbeispiel 6 stellt einen selbstdesinfizierenden Geruchverschluß in
der Form eines gebräuchlichen Röhrensifons in minimaler Instrumentierung
dar, der folgendermaßen ausgerüstet ist:
Ausführungsbeispiel 7 stellt einen selbstdesinfizierenden Geruchverschluß in
der Form eines gebräuchlichen Flaschensifons in minimaler Instrumentierung
(Ausführungsbeispiel 6) dar, wobei die Heizung aus einer in die
Sperrflüssigkeit hinein-ragenden Heizlampe besteht.
Ausführungsbeispiel 8 stellt einen selbstdesinfizierenden Geruchverschluß in
der Form eines gebräuchlichen Flaschensifons in minimaler Instrumentierung
dar, wobei der Sifonkörper aus für Lichtstrahlung durchlässigem Material
gefertigt ist und die Heizung durch eine außerhalb des Geruchverschlusses
angebrachte Heizlampe erfolgt.
