Die Durchführung des Verfahrens der Erfindung mit der Vorrichtung zu seiner Durchführung wird nach den Figuren 1 bis 5 in dem folgenden Ausführungsbeispiel beschrieben.The implementation of the method of the invention with the device for carrying it out is described in accordance with FIGS. 1 to 5 in the following exemplary embodiment.

Die an die Wasser- und Stromleitung angeschlossene Vorrichtung wird durch das Pflegepersonal ohne Berührung mit der Hand durch Tastendruck mit dem Ellbogen geöffnet. Die sich vertikal nach oben öffnende Tür (2) gibt die Spülkammer (1) frei. Es wird das zu reinigende Hygienegefäss (19) in Form eines Steckbecken in eine schwenkbare Halterung (4) auf einer Drehvorrichtung (3) eingeführt. Es wird dann durch das Pflegepersonal durch Knopfdruck mit dem Ellbogen über einen Tastschalter das Reinigungsprogramm nach Programmablauf der Verfahrensstufen eingeleitet.The device connected to the water and power line is opened by the nursing staff without touching the hand by pressing a button with the elbow. The door (2) that opens vertically upwards releases the rinsing chamber (1). The hygiene vessel (19) to be cleaned is introduced in the form of a bedpan into a pivotable holder (4) on a rotating device (3). The cleaning program is then initiated by the nursing staff by pressing a button on the elbow with a button switch after the program of the process steps has been completed.

Es erfolgt das automatische Schliessen der Schiebetür (2) durch deren Absenkung, wodurch der Innenraum wasser- und dampfdicht nach aussen abgeschlossen wird. Mit der Schliessung der Schiebetür (2) erfolgt gleichzeitig die Drehbewegung der Drehvorrichtung (3) und dadurch die Entleerung des Hygienegefässes (19) nach unten in den konischen Auslauf (17) der Spülkammer (1). Danach erfolgt die Reinigung des innenraumes der Spülkammer (1) und der Aussenfläche des Hygienegefässes (19) kurzzeitig und vollständig über eine an der Decke der Spülkammer (1) befindlichen Drehdüse (8) gemäss der Darstellung in Figur 1.The sliding door (2) is automatically closed by lowering it, which means that the interior is sealed to the outside in a water- and steam-tight manner. When the sliding door (2) is closed, the rotary device (3) rotates and the hygiene vessel (19) is emptied down into the conical outlet (17) of the washing chamber (1). The interior of the rinsing chamber (1) and the outer surface of the hygiene container (19) are then cleaned briefly and completely using a rotary nozzle (8) located on the ceiling of the rinsing chamber (1) as shown in FIG. 1.

Die Reinigung erfolgt nicht wie nach dem Stand der Technik aus einer sich im unteren Teil der Spülkammer (1) befindlichen Leitung, sondern mit Druckwasser über die nach allen Richtungen und Seiten spritzende, auswechselbare Drehdüse (8), wobei das Schmutzwasser über den Syphon (18) des unteren konischen Teiles (17) der Spülkammer (1) abfliesst.The cleaning does not take place from a line located in the lower part of the rinsing chamber (1) as in the state of the art, but with pressurized water via the interchangeable rotating nozzle (8) spraying in all directions and sides, the dirty water via the siphon (18 ) of the lower conical part (17) of the rinsing chamber (1) flows off.

Nach automatischer Abschaltung des Reinigungsvorganges erfolgt die Öffnung der durch die Kammerwand der Spülkammer (1) in den Innenraum führenden Leitung (12), die mit einer Leitung (14) über eine Drehkupplung (13) verbunden ist. Die Leitung (14) führt zu einer Düse (15) an der Drehvorrichtung (3). Durch diese Leitungen wird Druckwasser über die Düse (15) mit gegenüber dem Druck der Drehdüse (8) erhöhtem Fliessdruck intensiv und optimal in das Hygienegefäss eingespritzt.After the cleaning process has been switched off automatically, the line (12) leading through the chamber wall of the rinsing chamber (1) into the interior is opened and is connected to a line (14) via a rotary coupling (13). The line (14) leads to a nozzle (15) on the rotating device (3). Through these lines, pressurized water is injected intensively and optimally into the hygiene vessel via the nozzle (15) with a flow pressure that is higher than the pressure of the rotary nozzle (8).

Die optimale Wirkung bei minimalem Wasserverbrauch wird durch den technischen Effekt der gleichzeitigen Drehung der Düse (15) - 'sammen mit dem Hygienegefäss in der Drehvorrichtung (3) bewirkt.The optimal effect with minimal water consumption is brought about by the technical effect of the simultaneous rotation of the nozzle (15) - 'together with the hygiene container in the rotating device (3).

Es wird dabei gleichzeitig der untere Teil der Spülkammer (1) gereinigt, wobei das Reinigungswasser über den Syphon (18) im unteren, konischen Teil (17) der Spülkammer (1) abfliesst. Figur 2 zeigt die Drehbewegung der Drehvorrichtung (3) mit dem Hygienegefäss (19) um einen Winkel bis etwa 140°, sowie den für die Drehung erforderlichen Motor (5) und eine Umlenkrolle (6). Danach erfolgt die Desinfektion des entleerten und gereinigten Hygienegefässes (19), sowie des Innenraumes der Spülkammer (1) durch Eintritt von Warmwasser durch die Leitung (27) über die kurze Freistrecke (28) oberhalb des Wasserspiegels im Wasserbehälter (11) in eine trichterförmige Erweiterung (29) und gelangt danach über eine U-förmig gebogene Strecke (31) gemäss der Darstellung in Figur 5 in den Dampfgenerator.At the same time, the lower part of the rinsing chamber (1) is cleaned, the cleaning water flowing off via the siphon (18) in the lower, conical part (17) of the rinsing chamber (1). Figure 2 shows the rotary movement of the rotating device (3) with the hygiene container (19) through an angle of up to approximately 140 °, as well as the motor (5) required for the rotation and a deflection roller (6). The emptied and cleaned hygiene vessel (19) and the interior of the rinsing chamber (1) are then disinfected by hot water entering through the line (27) via the short free path (28) above the water level in the water tank (11) into a funnel-shaped extension (29) and then reaches the steam generator via a U-shaped path (31) as shown in FIG. 5.

Aus diesem tritt oberhalb des konischen Teiles (17) Sattdampf von etwa 100 °C oder überhitzter Dampf je nach den gestellten Anforderungen an die Desinfektion durch die Wand der Spülkammer (1) in diese ein.From this, saturated steam of about 100 ° C. or superheated steam enters the wall of the rinsing chamber (1), depending on the requirements placed on the disinfection, above the conical part (17).

Die kurze Freistrecke (28) bietet die notwendige Sicherheit gegen Rücklauf des Wassers bei einem möglichen Störungsfall..The short free path (28) offers the necessary security against water return in the event of a possible malfunction.

Es erfolgt danach die automatische Öffnung der Schiebetür (2) nach oben unter gleichzeitiger Rückschwenkung der Befestigungshalterung (4) in umgekehrter Richtung und danach die Entnahme des leeren, gereinigten Hygienegefässes.The sliding door (2) is then automatically opened upwards while the mounting bracket (4) swings back in the opposite direction and the empty, cleaned hygiene container is then removed.

In Figur 1 ist auch die Kondensationseinrichtung des Wasserdampfes mittels eines Überlauf- und Kondensationsrohres (20) dargestellt, dass bis oberhalb des Wasserspiegels in dem Wasserbehälter (11) in der Spülkammer (1) reicht. Zum Druckausgleich dient eine Entlüftungsöffnung (21) im Wasserbehälter (11 ).FIG. 1 also shows the condensation device for the water vapor by means of an overflow and condensation tube (20) that extends to above the water level in the water tank (11) in the rinsing chamber (1). A vent opening (21) in the water tank (11) serves to equalize the pressure.

In Figur 3 ist alternativ die Kondensation des Wasserdampfes in einem Überlauf- und Kondensationsrohres (20) mittels des in einem Kühlmantel (26) strömenden Kühlwassers dargestellt.FIG. 3 alternatively shows the condensation of the water vapor in an overflow and condensation tube (20) by means of the cooling water flowing in a cooling jacket (26).

In Figur 4.1 ist ein rundes Steckbecken, in Figur 4.2 eine nierenförmige Form ; in Figur 4.3 eine keilförmige Ausführung dargestellt, die in die Befestigungshalterung (4) eingesetzt werden können.In Figure 4.1 is a round bedpan, in Figure 4.2 a kidney shape; in Figure 4. 3 shows a wedge-shaped design that can be used in the mounting bracket (4).

In Figur 3 wird auch eine weitere Ausbildung der Vorrichtung dargestellt. Es wird anstelle der Drehkupplung (13) die Düse (23) zur Wasserführung angeschlossen, und das Druckwasser in einen offenen Auffangtrichter (24) eingedrückt, der mit der Leitung (14) verbunden ist, an welche beispielsweise 3 Spritzdüsen (25) angeschlossen sind, deren Wasserstrahl nach oben gerichtet ist und zwar in die nach unten gerichteten Öffnungen der sich in einem nicht schwenkbaren, auswechselbaren Einsatzkorb (22) befindlichen Hygienegefässe (19) in Form von Urinflaschen.A further embodiment of the device is also shown in FIG. Instead of the rotary coupling (13), the nozzle (23) is connected to guide the water, and the pressurized water is pressed into an open collecting funnel (24) which is connected to the line (14) to which, for example, 3 spray nozzles (25) are connected, whose water jet is directed upwards into the Bottom-facing openings of the hygiene vessels (19) in the form of urine bottles located in a non-swiveling, exchangeable insert basket (22).

Die Figur 3 zeigt auch den Einsatz des Einsatzkorbes (22) anstelle der Drehvorrichtung (3) und dessen Auflage auf Schienen.FIG. 3 also shows the use of the insert basket (22) instead of the rotating device (3) and its support on rails.

Diese alternative Ausführung des Verfahren und der Vorrichtung der Erfindung zeigt das direkte Einspritzen des Druckwassers in die enghalsige Urinflaschen und damit deren optimale Reinigung mit minimaler Wassermenge, wobei die äussere Reinigung dieser Flaschen und des Innenraumes der Spülkammer (1) über das Druckwasser aus der Drehdüse (8) in gleicher Weise durch das Gitter des Drahtkorbes (22) erfolgt.This alternative embodiment of the method and the device of the invention shows the direct injection of the pressurized water into the narrow-necked urine bottles and thus their optimal cleaning with a minimal amount of water, the external cleaning of these bottles and the interior of the rinsing chamber (1) using the pressurized water from the rotary nozzle ( 8) in the same way through the grid of the wire basket (22).

Dieser Einsatzkorb für die Reinigung mehrerer Flaschen ist leicht auswechselbar, da dieser nur auf den Schienen aufliegt und keine feste Verbindung für Einspritzwasser benötigt wird, welches durch den Auffangtrichter (24) frei in die Leitung (14) und in die Spritzdüsen eintritt.This insert basket for cleaning several bottles is easy to replace, since it only rests on the rails and no fixed connection is required for injection water, which freely enters the line (14) and the spray nozzles through the collecting funnel (24).

Die kurzzeitige Reinigung der Hygienegefässe mit Druckwasser erfolgt in etwa 10 bis 60 sec bei einem Fliessdruck von etwa 1,5 bis 2,5 bar.The hygienic vessels are briefly cleaned with pressurized water in about 10 to 60 seconds at a flow pressure of about 1.5 to 2.5 bar.

Das Reinigungswasser hat Raumtemperatur oder als Mischwasser eine Temperatur von etwa 40° bis 50 °C.The cleaning water has room temperature or as mixed water a temperature of about 40 ° to 50 ° C.

Die Minimierung des Wasserverbrauches ergibt sich beispielsweise aus folgenden Wassermengen :

  • Es werden bei der Reinigung des Innenraumes der Spülkammer (1) und der Aussenflächen des Hygienegefässes aus der Drehdüse (8) etwa 8 bis 10 I Wasser und zur Reinigung des Hygienegefässes (19) aus der Düse (15) an der Drehvorrichtung (3) etwa 8 bis 15 I Wasser und zur Desinfektion durch Dampf etwa 200 bis 300 cm3 Wasser benötigt.
The minimization of water consumption results, for example, from the following amounts of water:
  • When cleaning the interior of the rinsing chamber (1) and the outer surfaces of the hygiene vessel from the rotary nozzle (8), about 8 to 10 liters of water are used and for cleaning the hygiene vessel (19) from the nozzle (15) on the rotary device (3) 8 to 15 l of water and about 200 to 300 cm 3 of water are required for steam disinfection.

Durch die Auswahl der Düsenform der Düse (15) an der Drehvorrichtung (3) und durch die Änderung des Abstandes von der Düsenöffnung bis zum Boden des eingesetzten Hygienegefässes unterschiedlicher Form durch Auswechseln der Drehvorrichtung (3) mit der Leitung zur Zuführung des Druckwassers kann ein optimaler Reinigungseffekt bei minimalen Wasserverbrauch eingestellt werden.By selecting the nozzle shape of the nozzle (15) on the rotating device (3) and by changing the distance from the nozzle opening to the bottom of the hygiene container used, different shapes by replacing the rotating device (3) with the line for supplying the pressurized water can be an optimal one Cleaning effect can be set with minimal water consumption.

Das Verfahren der Erfindung mit der Vorrichtung zu seiner Durchführung bietet den Vorteil gegenüber dem Stand der Technik, dass dieses keine Vielzahl von verzweigten Leitungen mit Düsen benötigt, die auch zu Verkrustungen führen können, zu deren Vermeidung ein erheblicher Aufwand erforderlich ist. Dieser wird mit den beiden Düsen (8, 15) nach der Arbeitsweise der Erfindung vermieden. Das Verfahren der Erfindung bietet mit der Vorrichtung zu seiner Durchführung den weiteren Vorteil, dass für den Fall einer Betriebsunterbrechung durch einen Störungsfall keine Rücksaugung von Dampf oder Wasser eintreten kann. Ein Austritt erfolgt dann lediglich innerhalb des Spülraumes der Spülkammer. Es kann also etwaiges Verlustwasser ohne besonderen Aufwand aufgefangen werden.The method of the invention with the device for carrying it out has the advantage over the prior art that it does not require a large number of branched lines with nozzles, which can also lead to incrustations, the avoidance of which requires considerable effort. This is avoided with the two nozzles (8, 15) according to the method of operation of the invention. The method of the invention with the device for carrying it out has the further advantage that, in the event of an interruption in operation due to a malfunction, steam or water cannot be sucked back. An exit then takes place only within the washing compartment of the washing chamber. Any waste water can therefore be collected without any special effort.
