Abstract

A waterless urinal (1) is provided with a pot (17) in which urine (35) accumulates. A float (33) floats on the urine (35) and is pressed upwardly by the buoyancy thereof against an opening (31) in the cover (29) of the pot (17). As soon as a pre-determinable column of urine rises above the float (33), the float (33) is pressed downwardly, and the urine (35) can flow out. In a preferred embodiment, the float (33) can be pulled downwardly by an electromagnet, in order to sporadically empty the urine (35), which has accumulated above the float (33) and the cover (29).

Description

Gegenstand der Erfindung ist ein Geruchsverschluss für ein Urinal gemäss Oberbegriff des Patentanspruches 1.The invention relates to an odor trap for a Urinal according to the preamble of claim 1.

Aus dem Stand der Technik sind Urinale bekannt, die nach jeder Benutzung mit Wasser gespült werden müssen. Durch die Reduktion der Spülwassermenge infolge höherer Wasserpreise und/oder geringer zur Verfügung stehender Wassermenge benötigen solche Urinale einen unverhältnismässig hohen Reinigungsaufwand. Durch die Vermengung von Urin mit Wasser wird die Bildung von Urinstein gefördert und nicht nur Teile des Urinals, sondern insbesondere auch die von diesem wegführende, einen Siphon aufweisende Abflussleitung wird innert weniger Monate durch Aufbau von Urinstein im Querschnitt vermindert und muss folglich gereinigt werden. Nebst den hohen Kosten für das notwendige Spülwasser kommen solche für die periodische Reinigung/Reparatur der Leitungen hinzu. Urinals are known from the prior art, which according to must be rinsed with water each time it is used. By the reduction of the amount of rinsing water due to higher Water prices and / or less available Such urinals need a lot of water disproportionately high cleaning effort. Through the Mixing urine with water will form Urine stone promoted and not just parts of the urinal, but especially those leading away from it, a drain pipe with a siphon is inside less months due to the build-up of urine stone in cross-section reduced and must therefore be cleaned. Besides that high costs for the necessary rinse water come such for periodic cleaning / repair of the lines added.

Es sind aus diesen Gründen schon wasserlose Urinale vorgeschlagen worden. Aus der DE-A1 28 16 597 (Ernst) ist ein topfförmiger Einsatz bekannt, der in eine am tiefsten Punkt des Urinals befindliche Ausnehmung eingesteckt und mit dem Ablaufrohr verbunden wird. Im Einsatz ist ein ringförmiger Raum ausgebildet, in welchen von oben ein zylindermantelförmiges Rohr eingeschoben wird, welches den ringförmigen Raum in zwei Bereiche, einen inneren und einen äusseren unterteilt, die miteinander verbunden sind und eine Geruchssperre, bzw. einen Siphon bilden. Im äusseren Ringraum ist eine Sperrflüssigkeit von geringerer Dichte als Wasser, z.B. Oel, vorhanden. Der in den Behälter eintretende Urin durchquert wegen seines höheren spezifischen Gewichts die Sperrflüssigkeit und gelangt so in den Ablauf und von dort zur Kanalisation. Diese Vorrichtung hat den Nachteil, dass die Sperrflüssigkeit, die zusätzlich desinfizierende Wirkstoffe und allenfalls Duftstoffe enthalten kann, bei der periodischen Reinigung des Urinals mit einem starken Wasserschwall sukzessive durch die starke Strömung des Wassers durch die Sperrflüssigkeit hindurch weggespült wird und somit ihre Wirkung verliert.For these reasons, they are already waterless urinals been proposed. From DE-A1 28 16 597 (Ernst) a pot-shaped insert known to be the deepest in one Recess located at the point of the urinal and is connected to the drain pipe. A is in use annular space, in which from above cylinder-shaped tube is inserted, which the annular space in two areas, an inner and an exterior divided, which are interconnected and form an odor barrier or a siphon. in the outer annulus is a barrier liquid of less Density than water, e.g. Oil, available. The one in the Urine entering container traverses because of its higher specific weight of the barrier liquid and thus arrives in the drain and from there to the sewage system. This The disadvantage of the device is that the sealing liquid, the additional disinfectants and if necessary May contain fragrances during periodic cleaning of the urinal with a strong surge of water successively by the strong flow of water through the Barrier liquid is washed away and thus their Loses effect.

In der internationalen Patentanmeldung WO-A-97/15735 wird ein Einsatz für ein wasserloses Urinal mit einer Sperrflüssigkeit offenbart, welches durch die spezielle geometrische Ausbildung des Einsatz-Behälters das Wegschwemmen der Sperrflüssigkeit verhindern soll. Auch wenn das Wegschwemmen der Sperrflüssigkeit dort im wesentlichen verhindert wird, lässt sich dennoch nicht vermeiden, dass dessen Wirkstoffe, die notwendig sind um einen einwandfreien Geruchsschutz zu bilden, sukzessive abgebaut werden und folglich auch bei dieser Anordnung die Sperrflüssigkeit häufig ersetzt werden muss. Auch sind Stoffe, welche für die Sperrflüssigkeit eingesetzt werden, nicht völlig unbedenklich und können zu Problemen bei der Abwasseraufbereitung führen. Zusätzliche Schwierigkeiten bietet die Überwachung des momentanen Zustands der Sperrflüssigkeit, da diese direkt nicht einsehbar ist und im Prinzip nur die Nase entscheidet, ob noch genügend davon vorhanden ist oder ob diese bereits abgebaut oder doch weggespült ist.In international patent application WO-A-97/15735 an insert for a waterless urinal with a Barrier liquid revealed, which by the special geometric design of the insert container To prevent the barrier liquid from washing away. Also when the flooding of the barrier liquid there in the is essentially prevented, but can not avoid its active ingredients that are necessary to to form perfect odor protection, successively be dismantled and consequently also in this arrangement Barrier fluid must be replaced frequently. Also are Substances used for the barrier liquid not completely harmless and can cause problems with the Lead wastewater treatment. Additional difficulties provides monitoring of the current state of the Barrier liquid, as this is not directly visible and in principle only the nose decides whether there is still enough of which is present or whether it has already been dismantled or is washed away.

Die Aufgabe der vorliegenden Erfindung ist die Schaffung eines Geruchsverschlusses, welcher ohne Sperrflüssigkeit auskommt.The object of the present invention is to create an odor trap, which without barrier liquid gets along.

Gelöst wird diese Aufgabe durch einen Geruchsverschluss mit den Merkmalen des Patentanspruches 1. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen definiert.This task is solved by an odor trap with the features of claim 1. Advantageous Embodiments of the invention are in the dependent Defined claims.

Die erfindungsgemässe Anordnung arbeitet völlig ohne Sperrflüssigkeit und kann demzufolge, falls notwendig, periodisch ohne weiteres mit einem Wasserschwall gründlich gereinigt werden. Zudem liegt ein doppelter Geruchsverschluss vor, in dem zum einen die im Einsatz-Behälter gestaute Flüssigkeit, nämlich der Urin, den Geruch aus der Kanalisation einwandfrei sperrt und zudem als zweite Dichtung die linien- oder streifenförmige Anlage des Schwimmerkörpers an der Sammelfläche den Austritt von Gerüchen verhindert. Ein Aufbau von Urinstein entfällt vollständig, da die für dessen Bildung notwendigen Anteile von Wasser nicht vorhanden sind. Das bei der periodischen Reinigung allenfalls verwendete Wasser ist für den Aufbau von Urinstein vernachlässigbar, weil diese nur ganz kurzfristig mit dem Urinrest reagieren kann. Der Auftrieb des Auftriebskörpers ist derart bemessen, dass die sich im Deckel sammelnde Urinmenge (Flüssigkeitssäule) ausreicht, den Auftriebskörper zeitweilig so weit abzusenken bzw. anzuheben, dass der Urin nach unten abfliessen kann. Bei Verwendung eines kugelförmigen Auftriebskörpers liegt dieser zwangsläufig immer an der kreisrunden Öffnung an. Zusätzlich an der Öffnung angebrachte Dichtmittel können zur Erhöhung der Dichtigkeit angebracht sein. In einer besonderen Ausgestaltung der Erfindung kann unterhalb des ersten Behälterabschnitts, in welchem der Auftriebskörper schwimmt, ein Magnet angeordnet werden, mit welchem der Auftriebskörper sporadisch nach unten gezogen und so die oberhalb dessen Oberfläche befindliche Urinmenge vollständig abgeleitet werden kann. Auf diese Weise lässt sich in Zeiten, in denen das Urinal wenig benutzt wird, die gestaute Flüssigkeitsmenge sporadisch wegführen. Vorteilhafterweise wird der Magnet über einen durch eine lichtempfindliche Zelle gespeisten Kondensator erregt.The arrangement according to the invention works completely without Sealing liquid and, if necessary, periodically thoroughly with a gush of water getting cleaned. There is also a double one Odor trap before, in the one in the insert container accumulated fluid, namely the urine, the Odor from the sewage system is perfectly blocked and also as a second seal, the linear or striped Place the float on the quilt Prevents odors from escaping. A build up of urine stone is completely omitted because of its formation necessary proportions of water are not available. The used for periodic cleaning if necessary Water is negligible for the build-up of urine stone, because they only react with the urine residue for a very short time can. The buoyancy of the buoyancy body is such measured that the amount of urine collecting in the lid (Liquid column) is sufficient, the buoyancy body temporarily lower or raise so far that the Urine can flow down. When using a spherical buoyant body inevitably lies always at the circular opening. Additionally at the Sealants can be used to increase the opening Tightness should be appropriate. In a special one Embodiment of the invention can be below the first Section of the container in which the buoyancy body floats, a magnet can be arranged with which the The float is sporadically pulled down and so the amount of urine above its surface can be fully derived. That way at times when the urinal is used little Remove the accumulated amount of liquid sporadically. Advantageously, the magnet is replaced by a photosensitive cell powered capacitor excited.

In einer weiteren Ausgestaltung der Erfindung weist der Auftriebskörper einen u-förmigen Querschnitt auf und bedeckt das obere Ende des Ablaufstutzens am Behälter. Durch diese Ausbildungsform entfällt das Einsetzen einer zusätzlichen, den Geruch zurückhaltenden Tauchwand.In a further embodiment of the invention, the Buoyancy body has a u-shaped cross section on and covers the upper end of the drain socket on the tank. This type of training means that there is no need to use one additional baffle that retains the smell.

In the transition between the sump 9 and the recess 11 preferably a circumferential shoulder 13 formed on which the flange 15 one in the recess 11th inserted pot-shaped insert container, short pot 17 rests.

In der ersten Ausgestaltung des einen Geruchsverschluss bildenden Topfes 17, der einen Mantel 19 umfasst und dessen Boden 21 von einem Ablaufstutzen 23 durchdrungen wird, ist ferner ein behälterförmiger Raum, fortan Schwimmerraum 25 genannt, angeordnet. Mindestens ein Teil seines Mantels kann mit dem Mantel 19 des Topfes 17 gemeinsam sein. Eine sehnenförmig verlaufende Wand 18 trennt den Schwimmerraum 25 von einen Überlaufraum 27 und dem oberen Teil 23 des Ablaufstutzens 5, der mit dem Kopfraum 28 des Überlaufraums 27 verbunden ist. Der obere Teil 23 kann durch zwei Wandteile 24 oder durch ein Rohr (nicht dargestellt) gebildet sein. Das obere Ende 22 des Teils 23 liegt in einem vertikalen Abstand zum Absatz 13.In the first embodiment of an odor trap forming pot 17, which comprises a jacket 19 and whose bottom 21 is penetrated by a drain pipe 23 is also a container-shaped room, henceforth Called float room 25, arranged. At least part of it its jacket can with the jacket 19 of the pot 17th be together. A chord-shaped wall 18 separates the float chamber 25 from an overflow chamber 27 and the upper part 23 of the drain connector 5, which with the Head space 28 of the overflow space 27 is connected. The upper Part 23 can be through two wall parts 24 or through a tube (not shown) be formed. The upper end 22 of the Part 23 is at a vertical distance from paragraph 13.

Die obere Öffnung des Topfes 17 ist durch einen kegelstumpfförmigen Deckel 29, an dessen tiefster Stelle eine kreisrunde Öffnung 31 angebracht ist, abgedeckt. Die Öffnung 31 liegt über dem Schwimmerraum 25. Der Schwimmerraum 25 und der mindestens eine Überlaufraum 27 sind unten durch eine Verbindungsöffnung 37 miteinander verbunden.The upper opening of the pot 17 is through a frustoconical cover 29, at its lowest point a circular opening 31 is attached, covered. The Opening 31 lies above the float chamber 25 Float chamber 25 and the at least one overflow chamber 27 are below each other through a connection opening 37 connected.

Innerhalb des Schwimmerraums 25 liegt ein frei beweglicher Schwimmerkörper 33, im ersten Beispiel gemäss Figur 2 eine Kugel, deren spezifische Dichte geringer ist als die Dichte von Urin 35. Der Durchmesser D der Kugel ist grösser als der Durchmesser d der Öffnung 31 im Deckel 29.Within the float chamber 25 there is a freely movable one Float body 33, one in the first example according to FIG Sphere whose specific density is less than that Density of urine 35. The diameter D of the ball is greater than the diameter d of the opening 31 in the cover 29.

Unterhalb des Flansches 15 am Deckel 29 kann ein O-Ring oder eine anders ausgebildete Dichtung 39 angeordnet sein.An O-ring can be located below the flange 15 on the cover 29 or a differently designed seal 39 can be arranged.

Sobald die Flüssigkeitssäule über der Öffnung 31 im Deckel 29 gewichtmässig den Auftrieb des Schwimmerkörpers 33 im Schwimmerraum 25 übersteigt und folglich grösser als die Anpresskraft des Schwimmerkörpers 33 am Deckel 29 ist, wird der Schmimmerkörper 33 nach unten gedrückt und der angesammelte Urin 35 kann durch den sich öffnenden Spalt nach unten abfliessen. Er gelangt dann in den Schwimmerraum 25, von dort durch die Durchtrittsöffnung 37 zum Überlaufraum 27 und danach in den Ablaufstutzen 5. Die Oberkante des oberen Teils 23 des Ablaufstutzens 5 liegt auf einer Höhe, welche sicherstellt, dass der Schwimmerkörper 33 an die Öffnung 31 angepresst wird, wobei die Anpresskraft, das heisst der Auftrieb ausreicht, um einen einwandfreien Verschluss zu gewährleisten und gleichzeitig den Abfluss auch schon einer geringen Menge (d.h. bereits einer Flüssigkeitssäule von z.B. 10mm) Urin 35 auf dem Deckel 29 zu ermöglichen.Urine 35 flowing into the collecting pan 9 collects from above on the lid 29. Once the liquid column is over the opening 31 in the cover 29 by weight the buoyancy of the Float body 33 in the float chamber 25 exceeds and consequently greater than the contact pressure of the float body 33 is on the lid 29, the float body 33 after pressed down and the accumulated urine 35 can through the flowing down gap opening. He arrives then into the float room 25, from there through the Passage opening 37 to the overflow space 27 and then in the drain pipe 5. The upper edge of the upper part 23 of the Drain pipe 5 is at a height, which ensures that the float body 33 at the opening 31 is pressed, the contact pressure, that is the Buoyancy is sufficient to ensure a perfect closure guarantee and at the same time the drain a small amount (i.e. already a liquid column from e.g. 10mm) to allow urine 35 on the lid 29.

In der zweiten Ausgestaltung der Erfindung gemäss Figur 3 liegt der Ablaufstutzen 23 im Zentrum des Schwimmerraums 25, der in diesem Beispiel identisch mit dem Topf 17 ist. Der rotationssymmetrisch geformte Schwimmerkörper 33 weist einen u-förmigen Querschnitt auf und kann als Hohlkörper oder aus einem Material gefertigt sein, das eine geringere Dichte als Urin aufweist.
