Description

Die vorliegende Erfindung betrifft eine wasserlose Sanitäranlage gemäss dem Oberbegriff nach Anspruch 1 sowie ein Verfahren für den Betrieb einer wasserlosen Sanitäranlage.The present invention relates to a waterless sanitary installation according to the preamble of claim 1 and to a method for operating a waterless sanitary installation.

Wasserlose Sanitäranlage, insbesondere wasserlose Urinale, weisen in der Regel keine Wasserspülung auf. Die Desinfektion bzw. Unterdrückung der Geruchsbildung erfolgt bei solchen Anlagen in der Regel mittels Siphoneinsatzes. Derartige Urinale sind beispielsweise aus der CH 690 917 , der DE 270 361 , der WO 94/25693 und der EP 0 903 444 bekannt. Dabei sind Siphoneinsätze vorgesehen, beispielsweise enthaltend eine Sperrflüssigkeit zur Verhinderung der Geruchsbildung. Die verwendeten Sperrflüssigkeiten sind beispielsweise ölartig und/oder weisen eine Dichte von ca. 0,9 g/cm3 auf, so dass sie die im Siphon gebildete Flüssigkeitsverbindung, welche in der Regel Urin enthält, überdecken und so das Entweichen von Gasen bzw. von Geruch verhindern.Waterless sanitary facilities, in particular waterless urinals, generally have no water rinse. The disinfection or suppression of odor formation takes place in such systems usually by siphon use. Such urinals are for example from the CH 690 917 , of the DE 270 361 , of the WO 94/25693 and the EP 0 903 444 known. In this case, siphon inserts are provided, for example containing a barrier liquid to prevent the formation of odors. The barrier fluids used are, for example, oily and / or have a density of about 0.9 g / cm 3 , so that they cover the liquid compound formed in the siphon, which usually contains urine, and thus the escape of gases or of Prevent odor.

Der Nachteil der bekannten wasserlosen Urinale mit Sperrflüssigkeit besteht darin, dass die Sperrflüssigkeit oft nachgefüllt werden muss, da jeweils mindestens ein Teil derselben durch die den Siphon hindurch tretende Flüssigkeit, wie insbesondere dem Urin, mitgerissen wird.The disadvantage of the known waterless urinals with barrier liquid is that the barrier liquid often has to be topped up, since in each case at least a part of them is entrained by the liquid passing through the siphon, in particular the urine.

Es ist deshalb eine Aufgabe der vorliegenden Erfindung ein wasserloses Urinal bzw. genereller eine wasserlose Sanitäranlage vorzuschlagen, bei welcher zur Verhinderung von Geruchsbildung nicht ständig Sperrflüssigkeit nachzufüllen ist bzw. bei welchem bzw. welcher die oben erwähnte Problematik verhindert werden kann.It is therefore an object of the present invention to propose a waterless urinal or, more generally, a waterless sanitary installation in which barrier liquid is not constantly used to prevent odor formation be refilled or in which or which the above-mentioned problems can be prevented.

Erfindungsgemäss wird eine sanitäre Anlage gemäss dem Wortlaut nach Anspruch 1 vorgeschlagen.According to the invention a sanitary system according to the wording of claim 1 is proposed.

Vorgeschlagen wird insbesondere eine wasserlose, sanitäre Anlage, wie insbesondere ein wasserloses Urinal, aufweisend ein Urinalbecken bzw. einen Urinalstand oder eine Schüssel in der Regel bestehend aus Keramik, Glas, Metall oder einem Polymermaterial sowie einen als Geruchsverschluss einsetzbaren Siphoneinsatz. Dieser besteht, wie bereits aus dem Stand der Technik bekannt, aus einem topfartigen Aussenteil mit einer im Wesentlichen zylindrischen Aussenwand und einem aus dem Boden des Aussenteils hochgeformten, zentralen Ablaufrohr zum ablaufseitigen Begrenzen eines im Aussenteil gebildeten, ringförmigen Aufnahmekanals für die Sperrflüssigkeit. Weiter besteht der Siphon aus einem in den Aufnahmekanal bzw. in die Sperrflüssigkeit hineinragenden Innenteil, welches das Ablaufrohr zur Bildung eines Ringkanales konzentrisch umschliesst. Erfindungsgemäss wird nun im Gegensatz zu den bekannten Siphoneinsätzen vorgeschlagen, dass im ringförmigen Aufnahmekanal ein Aufnahmebehältnis vorgesehen ist für die Aufnahme eines Sperrmediums derart, dass mindestens ein Teil des Sperrmediums mit der Sperrflüssigkeit bzw der Flüssigkeitsverbindung im Siphon in Kontakt steht.In particular, a waterless, sanitary facility is proposed, in particular a waterless urinal, comprising a urinal basin or a urinal stand or a bowl, as a rule consisting of ceramic, glass, metal or a polymer material, and a siphon insert which can be used as an odor trap. This consists, as already known from the prior art, of a pot-like outer part with a substantially cylindrical outer wall and a formed from the bottom of the outer part, the central drainage pipe for limiting the boundary formed in the outer part, an annular receiving channel for the barrier liquid. Next, the siphon consists of a projecting into the receiving channel or in the barrier liquid inner part, which encloses the drain pipe to form a ring channel concentrically. According to the invention it is now proposed in contrast to the known Siphoneinsätzen that in the annular receiving channel a receptacle is provided for receiving a barrier medium such that at least a portion of the barrier medium is in contact with the barrier liquid or the liquid connection in the siphon.

Dabei ist zu beachten, dass in der vorliegenden Erfindung als Sperrflüssigkeit die Flüssigkeitsverbindung verstanden wird, welche im Siphoneinsatz aus dem äusseren Aufnahmekanal mit dem innen liegenden Ringkanal verbunden ist bzw. im Aufnahmekanal und im Ringkanal, die beiden verbindend gelagert ist. Entsprechend besteht die Sperrflüssigkeit in der Regel vorwiegend aus Urin.It should be noted that in the present invention as a barrier fluid, the fluid connection is understood, which in the siphon used from the outside Receiving channel is connected to the inner annular channel or in the receiving channel and the annular channel, the two is mounted connecting. Accordingly, the barrier fluid is usually predominantly urine.

Dabei weist das Innenteil eine Verschlusskappe auf, derart, dass am Rand der Verschlusskappe ein vorzugsweise ringförmiger Spalt als Einlass zum ringförmigen Aufnahmekanal verbleibt, derart, dass die in den Siphoneinsatz gelangende Flüssigkeit, in der Regel weitgehendst bestehend aus Urin in das Aufnahmebehältnis, enthaltend das Sperrmedium, eingegeben wird.In this case, the inner part has a closure cap, such that at the edge of the closure cap a preferably annular gap remains as an inlet to the annular receiving channel, such that the reaching into the siphon insert liquid, usually largely consisting of urine in the receptacle containing the barrier medium , is entered.

Das Sperrmedium verhindert einerseits das Ausdünsten des im Siphon befindlichen Urins bzw. der Sperrflüssigkeit, wobei vorzugsweise das Sperrmedium über der oder in der Sperrflüssigkeit, wie insbesondere dem Urin schwimmt und über eine längere Zeitdauer geruchsverhindernde Wirkstoffe abgibt und sich dabei mit der Zeit auflöst. Beim Sperrmedium handelt es sich beispielsweise um vorzugsweise vollständig biologisch abbaubare natürliche Wachse bzw. Wachs/Öl-Gemische, beispielsweise in Form von Pillen, Kugeln, etc. Es kann sich dabei aber auch um sehr hochviskose Flüssigkeiten handeln, und vorzugsweise weist das Sperrmedium ein spezifisches Gewicht auf von 0,9 g/cm3 oder weniger auf, damit das Sperrmedium jeweils die den Urin enthaltende Sperrflüssigkeit überdeckt. Das Sperrmedium kann Zusätze enthalten, die antimikrobiell bzw. bakteriostatisch bis bakterizid wirken wie auch geruchsabsorbierend, indem reaktiv Kakosmophere, wie Schwefelwasserstoff, Mercaptane, Thioether, Isovaleriansäure, Ammoniak und Amine entfernt werden.The barrier medium prevents the one hand, the thinning of the urine or the barrier liquid in the siphon, wherein preferably the barrier medium floats above or in the barrier liquid, in particular the urine and releases odor-inhibiting agents over a longer period of time and dissolves over time. The barrier medium is, for example, preferably completely biodegradable natural waxes or wax / oil mixtures, for example in the form of pills, spheres, etc. However, these may also be very high-viscosity liquids, and preferably the barrier medium has a specific one Weight on from 0.9 g / cm 3 or less, so that the barrier medium covers each of the barrier fluid containing the urine. The barrier medium may contain additives that have an antimicrobial or bacteriostatic to bactericidal effect as well as odor-absorbing, by reactive Kakosmophere how Hydrogen sulfide, mercaptans, thioethers, isovaleric acid, ammonia and amines are removed.

Als Beispiele eines Sperrmediums seien an dieser Stelle gesättigte Fettalkohole und Fettsäuren, vorzugsweise pflanzlichen Ursprungs genannt, wie beispielsweise C11 - C29 Fettalkohole oder Fettsäuren.Examples of a barrier medium are saturated fatty alcohols and fatty acids, preferably of plant origin, such as C 11 -C 29 fatty alcohols or fatty acids.

Um eine ausreichende Geruchsverhinderung bzw. einen wirkungsvollen Abbau der geruchsbildenden Substanzen zu erreichen ist der Siphoneinsatz vorzugsweise derart ausgebildet, dass das Aufnahmebehältnis mit dem Sperrmedium ca. 50mm oder mehr in die Sperrflüssigkeit hinein ragt.In order to achieve a sufficient odor prevention or an effective degradation of the odor-forming substances, the siphon insert is preferably designed such that the receptacle projects with the blocking medium about 50 mm or more into the barrier liquid.

Zudem kann es vorteilhaft sein, dem Sperrmedium Additive beizufügen, wie beispielsweise Polyglykoläther bzw. Talgalkylpolyglykoläther, wie beispielsweise mit einer Kettenlänge von C16 - C18. Diese Additive gewährleisten das sukzessive Auflösen des Sperrmediums bzw. die Langzeitgeruchsverhinderung bzw. Verhinderung der GasbildungIn addition, it may be advantageous to add additives to the blocking medium, such as, for example, polyglycol ethers or tallow alkyl polyglycol ethers, for example with a chain length of C 16 -C 18 . These additives ensure the successive dissolution of the barrier medium or the long-term odor prevention or prevention of gas formation

Beim Siphoneinsatz handelt es sich vorzugsweise um ein austauschbares Masseteil, welches beispielsweise aus einem polymeren Material, wie beispielsweise Polyethylen, gefertigt ist.The siphon insert is preferably an exchangeable mass part, which is made, for example, from a polymeric material, such as polyethylene.

Weiter vorgeschlagen wird ein Verfahren gemäss dem Wortlaut nach Anspruch 11. Weitere bevorzugte Ausführungsvarianten sind in den abhängigen Ansprüchen charakterisiert und die Erfindung wird nun beispielsweise und unter Bezug auf die beigefügten Figuren näher erläutert.Further proposed is a method according to the wording of claim 11. Further preferred embodiments are characterized in the dependent claims and the invention will now be explained in more detail for example and with reference to the accompanying figures.

Figur 1 zeigt beispielsweise ein Keramikbecken 1 für eine wasserlose Urinanlage im seitlichen Querschnitt. Dabei schematisch dargestellt ist ein Siphoneinsatz 10 in einem Endrohr 30, mündend in einen angrenzenden Kanalanschluss 3.FIG. 1 shows, for example, a ceramic basin 1 for a waterless urine installation in the lateral cross section. Shown here is a siphon insert 10 in an end pipe 30, opening into an adjacent channel connection 3.

Der Siphoneinsatz 10 wird nun unter Bezug auf die nachfolgenden Figuren 2 bis 4 näher erläutert.The siphon insert 10 will now be explained in more detail with reference to the following figures 2 to 4.

Der Siphoneinsatz 10 besteht aus einem Aussenteil 11 und einem damit verbundenen Innenteil 12. Das Aussenteil 11 besitzt einen Boden 14, ein aus letzterem sich nach oben forterstreckendes zentrales Ablaufrohr 15 und eine sich über das Ablaufrohr 15 nach oben forterstreckende, zylindrische Aussenwand 16, die in einen sich zum Boden 14 hin verjüngenden Aussenkonus übergeht. Zwischen dem Ablaufrohr 15, dem Boden 14, dem konischen Abschnitt 17 und der Aussenwand 16 befindet sich ein Aufnahmekanal 18 für die Aufnahme der Sperrflüssigkeit, welche in der Regel weitgehendst aus Urin besteht.The siphon insert 10 consists of an outer part 11 and an inner part 12 connected thereto. The outer part 11 has a bottom 14, a central drain pipe 15 extending forwards from the latter and a cylindrical outer wall 16 extending forwards over the drain pipe 15 an outer cone tapering towards the bottom 14 merges. Between the drain pipe 15, the bottom 14, the conical portion 17 and the outer wall 16 is a receiving channel 18 for the inclusion of the barrier fluid, which usually consists largely of urine.

Das Innenteil 12 besteht aus einem im Bereich des oberen Randes der Aussenwand 16 eingesetzten Verschlusskappe 22 und aus einem Tauchrohr 23, die einstückig ausgebildet sind. Das Tauchrohr 23 erstreckt sich im Aufnahmekanal des Aussenteils 11 vertikal abwärts in die Sperrflüssigkeit und bildet somit einen konzentrisch zum Ablaufrohr 15 ausgebildeten Ringraum 20. Aufnahmekanal 18 und Ringraum 20 sind somit im Bereich des Bodens 14 miteinander kommunizierend verbunden für das Hindurchfliessen der Sperrflüssigkeit. Das Niveau der Sperrflüssigkeit wird dabei durch die obere Öffnung des Ablaufrohres 15 bestimmt. Der Siphoneinsatz 10 schliesslich ist in einem Siphonaufnahmerohr bzw. einem Endrohr 30, vorzugsweise wieder entfernbar bzw. austauschbar eingesetzt.The inner part 12 consists of an inserted in the region of the upper edge of the outer wall 16 cap 22 and a dip tube 23, which are integrally formed. The dip tube 23 extends in the receiving channel of the outer part 11 vertically downward in the barrier liquid and thus forms a concentric to the drain pipe 15 formed annular space 20. receiving channel 18 and annular space 20 are thus communicating in the region of the bottom 14 connected to each other for the passage of the barrier liquid. The level of the barrier liquid is determined by the upper opening of the drain pipe 15. Finally, the siphon insert 10 is inserted into a siphon receiving tube or an end tube 30, preferably removable again or interchangeably.

Im Gegensatz zu den bekannten Siphoneinsätzen weist nun der erfindungsgemässe Siphoneinsatz 10 ein ringförmig ausgebildetes Aufnahmebehältnis 25 auf, welches vorzugsweise im äusseren Aufnahmekanal 18 von oben her, beispielsweise eingehängt angeordnet ist. Im Aufnahmebehältnis 25 ist das Sperrmedium 29 vorsehen, wobei es sich beispielsweise um ein in Pillen- oder Kapselform ausgebildetes Wachs- oder ölartiges Material handeln kann, welches geeignet ist, die Geruchsbildung im Urin zu verhindern. Aufgrund des Aufnahmebehältnisses kann es sich dabei um ein x-beliebiges, geeignetes Material handeln. Vorzugsweise werden Materialien, wie biologisch abbaubare Wachse oder ölartige Substanzen gewählt, welche eine Dichte aufweisen die < als 0,9 g/cm3 ist, damit das Sperrmedium auch nach fortschreitendem Abbau die Sperrflüssigkeit bzw. den Urin nach wie vor überdeckt. Als Sperrmedien können beispielsweise gesättigte Fettalkohole oder Fettsäuren, vorzugsweise pflanzlichen Ursprungs, verwendet werden, beispielsweise aufweisend eine Kettenlänge von C11 - C29. Zudem kann es vorteilhaft sein ein Additiv zu verwenden, wie beispielsweise Alkylpolyglykoläther bzw. Talgalkylpolyglykoläther, vorzugsweise mit einer Kettenlänge von C16 - C18. Diese Additive dienen beispielsweise als Emulgatoren und ermöglichen ein Langzeitauflösen des in Pillen-, Kapsel- oder Granulatform vorliegenden Sperrmediums in der Sperrflüssigkeit.In contrast to the known siphon inserts, the siphon insert 10 according to the invention now has an annular receiving receptacle 25, which is preferably arranged in the outer receiving channel 18 from above, for example when hung up. In the receptacle 25, the barrier medium 29 is provided, which may be, for example, a trained in pill or capsule waxy or oily material, which is suitable to prevent the formation of odor in the urine. Due to the receptacle, it may be an x-any, suitable material. Preferably, materials such as biodegradable waxes or oily substances are selected which have a density <0.9 g / cm 3 , so that the barrier medium still covers the barrier fluid or urine, even after progressive degradation. As barrier media, for example, saturated fatty alcohols or fatty acids, preferably of vegetable origin, can be used, for example having a chain length of C 11 -C 29 . In addition, it may be advantageous to use an additive, such as, for example, alkyl polyglycol ethers or tallow alkyl polyglycol ethers, preferably having a chain length of C 16 -C 18 . These additives are used, for example, as emulsifiers and allow a long-term dissolution of the present in pills, capsules or granules blocking medium in the barrier liquid.

Figur 3 zeigt den Siphoneinsatz mit entfernter Verschlusskappe von oben, wobei im Aufnahmebehältnis 25 das Sperrmedium entfernt ist. Erkennbar sind nun Perforationen oder Lochungen 26 im Boden des Aufnahmebehältnisses 25, womit das Hindurchtreten des Urins durch das Aufnahmebehältnis gewährleistet ist. Der Urin gelangt, wie in Figur 2 erkennbar, durch einen Ringspalt 19, welcher sich peripher am Rand der Verschlusskappe 22 erstreckt, und fliesst direkt in den Innenraum des Aufnahmebehältnisses 25 und durch das Sperrmedium 29. Dabei löst sich das Sperrmedium über einem längeren Zeitabschnitt, wie beispielsweise 1 - 3 Monaten auf und verhindert so die Geruchsbildung. Anschliessend gelangt der Urin durch die Perforationen 26 in den Aufnahmekanal 18 und später in den Ringraum 20, um schliesslich durch das Ablaufrohr 15 in den Ablaufkanal 3 zu gelangen.FIG. 3 shows the siphon insert with the closure cap removed from above, wherein the blocking medium is removed in the receptacle 25. Can now be seen perforations or perforations 26 in the bottom of the receptacle 25, whereby the passage of the urine is ensured by the receptacle. The urine passes, as can be seen in Figure 2, through an annular gap 19 which extends peripherally at the edge of the cap 22, and flows directly into the interior of the receptacle 25 and through the blocking medium 29. In this case, the barrier medium dissolves over a longer period of time, as for example 1 to 3 months and thus prevents the formation of odors. Subsequently, the urine passes through the perforations 26 in the receiving channel 18 and later in the annulus 20, to finally pass through the drain pipe 15 into the drain channel 3.

In Figur 4 schliesslich ist das Aufnahmebehältnis 25 in Perspektive dargestellt, wodurch die ringförmige Ausbildung des Aufnahmebehältnisses deutlich erkennbar ist. Die Höhe vom Aufnahmebehältnis 25 muss derart gewählt sein, dass ein ausreichendes Eintauchen des Sperrmediums in die Sperrflüssigkeit und damit in die den Urin enthaltende Flüssigkeit gewährleistet ist.In Figure 4, finally, the receptacle 25 is shown in perspective, whereby the annular configuration of the receptacle is clearly visible. The height of the receptacle 25 must be selected such that a sufficient immersion of the barrier medium in the barrier liquid and thus in the urine-containing liquid is ensured.

Es ist sowohl möglich, jeweils nur das Aufnahmebehältnis 25 im Siphoneinsatz bzw. im Aufnahmekanal 18 als austauschbares Element zu ersetzen, wenn das Sperrmedium vollständig aufgelöst ist. Es ist aber auch möglich, den gesamten Siphoneinsatz als austauschbares Masseteil jeweils zu ersetzen, wenn das Sperrmedium vollständig aufgelöst bzw. aufgebraucht ist. In letzterem Falle kann das Aufnahmebehältnis 25 integraler Bestandteil des Siphoneinsatzes 10 sein. Dabei kann das Aufnahmebehältnis sowohl ebenfalls aus einem polymeren Material, wie beispielsweise Polyethylen, gefertigt sein, oder aber aus Metall, wie beispielsweise Eisenblech.It is both possible to replace only the receptacle 25 in the siphon insert or in the receiving channel 18 as an exchangeable element, respectively, when the blocking medium is completely dissolved. But it is also possible to replace the entire siphon insert as an exchangeable mass part in each case when the barrier medium is completely dissolved or used up. In the latter case, the receptacle 25 may be an integral part of the siphon insert 10. In this case, the receptacle can also be made of a polymeric material, such as polyethylene, or of metal, such as sheet iron.

Der erfindungsgemäss beschriebene Siphoneinsatz eignet sich für irgendwelche wasserlose sanitäre Anlagen bei welchen eine Geruchsbildung zu verhindern ist. In der Regel handelt es sich dabei um wasserlose UrinaleThe siphon used according to the invention is suitable for any waterless sanitary facilities in which an odor is to be prevented. As a rule, these are waterless urinals

Bei den in den Figuren 1 bis 4 dargestellten Beispielen handelt es sich selbstverständlich nur um mögliche Ausführungsformen um die vorliegende Erfindung näher zu erläutern. Selbstverständlich können Siphoneinsätze andersartig ausgebildet sein bzw. können durch weitere Elemente ergänzt werden. Erfindungswesentlich ist, das im Siphoneinsatz ein Aufnahmebehältnis vorgesehen ist für die Aufnahme eines Sperrmediums, um beim Abfliessen einer Flüssigkeit aus der sanitären Anlage, wie beispielsweise dem Urinal, Geruchsbildung, beispielsweise von austretendem Urin, zu verhindern.The examples illustrated in FIGS. 1 to 4 are of course only possible embodiments in order to explain the present invention in more detail. Of course, siphon inserts can be designed differently or can be supplemented by other elements. Essential to the invention is that in Siphon use a receptacle is provided for receiving a barrier medium to prevent the flow of liquid from the sanitary system, such as the urinal, odors, such as leaking urine.

Claims (11)

  1. Water free sanitary installation, as in particular a water free urinal installation, comprising an urinal bowl or urinal stand or a bowl made out of ceramic, glass, metal or a polymer material as well as a siphon-insert insertable as a smell-trap consisting of a pot-like outer part (11) with an essentially cylindrical outer wall (16) and a central drain pipe (15) formed upwards out of the bottom (14) to define a ring like collecting channel (18) within the outer part towards the drain for a sealing liquid and an inner part (12) extending into the collecting channel or the sealing liquid respectively, which surrounds the drain pipe (15) concentrically to create a ring channel (20), characterized in that within the ring like collecting channel (18) a collecting reservoir (25) is provided for the collection of a sealing medium (29), such that at least part of the sealing medium is in contact with the sealing liquid.
  2. Sanitary installation according to claim 1, characterized in that the inner part (12) comprises a sealing cap (22), such that at the border of the sealing cap a preferably ring-like gap (19) remains as entrance to the ring like collecting channel (18), such that a liquid entering into the siphon insert is feeded at least partially into the collecting reservoir (25).
  3. Sanitary installation according to one of the claims 1 or 2, characterized in that the siphon insert (10) consists of a polymeric material, such as e.g. Polyethylene and in that the collecting reservoir (25), also consisting of a polymeric material or out of metal, is at least permeable or porous.
  4. Sanitary installation according to one of the claims 1 to 3, characterized in that the sealing medium (29) does have a density which is less than the density of the sealing liquid, which e.g. mainly consists of urine.
  5. Sanitary installation according to one of the claims 1 to 4, characterized in that the sealing medium is at least high-viscous and/or is constituted of a wax or a wax/oil mixture with a density smaller than 0,95 g/cm3, preferably < 0,9g/cm3.
  6. Sanitary installation according to one of the claims 1 to 5, characterized in that the sealing medium is designed pill-like, bowl-like or granulate-like.
  7. Sanitary installation according to one of the claims 1 to 6, characterized in that the sealing medium comprises saturated fatty alcohols or fatty acids, preferably with vegetable bases, e.g. with the chain length of C11 - C29 such as for instance Laurylalcohol.
  8. Sanitary installation according to one of the claims 1 to 7, characterized in that the sealing medium further comprises an additive such as e.g. Alkylpolyglycolether or Tallowalkylpolyglycolether with a chain length of for instance C16 - C18.
  9. Sanitary installation according to one of the claims 1 to 8, characterized in that the collecting reservoir (25) with the sealing medium is arranged such that it is inserted into the sealing liquid by at least 50mm.
  10. Sanitary installation according to one of the claims 1 to 9, characterized in that the siphon insert is an exchangeable mass production component.
  11. Process for operating a sanitary installation according to one of the claims 1 to 10, characterized in that a liquid inserted into the sanitary installation, such as e.g. urine is decomposed or treated such by means of a high viscous sealing medium in wax or oily form, which is stored within a collecting reservoir (50) that the formation of smell can be prevented to a large extent.
