Definitions
- the invention relates to a urinal with flushing and additive with the features of the preamble of claim 1.
- the invention is therefore based on the object of developing a urinal with flushing and liquid additive in such a way that the above-mentioned disadvantages are countered and that a large amount of additive can be reliably introduced into the urinal without requiring additional space.
- the technical teaching of claim 1 serves to solve the problem.
- the tank and the mixing part are arranged in a free space in the upper region on the rear wall of the urinal basin, the mixing part containing a Venturi nozzle.
- This Venturi nozzle draws in domestic water via a line and the additive from the tank via a further line. The rinsing water mixed with the additive is then fed to the urinal basin.
- the tank can be easily refilled, because appropriate filling openings can be made on the top of the urinal basin, where they are easily accessible.
- the urinal basin 1 consists of a basin part 2, on the front edge of which an annular channel 6 is arranged, which has flushing nozzles 7 directed into the basin.
- These flushing nozzles 7 can either be present in a punctiform manner or it can be an all-round outlet channel which acts as a flushing nozzle 7.
- an outlet 8 is provided at the bottom of the basin part 2, in a manner known per se, to which a siphon 9 is connected.
- the rear of the urinal basin 1 has a free space 3, in which a tank 12 with a relatively high capacity for receiving an additive is installed.
- This tank 12 is filled from an upper fill opening 26 via a line 27. It has a removal line 11 which opens into a mixing part 10.
- the domestic water reaches the line 13 via the water inlet 15 and a corner valve 14, which also opens into the mixing part 10.
- the line 16 is connected, which the rinse water mixed with the additive contains.
- This line 16 opens into a recess 17 in the upper part of the ring channel 6, so that with the inlet into this recess 17, the rinsing water mixed with the additive is distributed over the entire ring channel 6 and over the entire length of the ring channel via the rinsing nozzles 7 in the Pool part 2 runs out.
- the rinsing process can be triggered by a rinsing button, which is not shown in detail.
- a magnetic valve 5, which is controlled by an electronic part 4, is assigned to the flushing button.
- the mixing part 10 according to FIG. 1 is shown in more detail in FIG. 2.
- the fresh water 13 passes into a Venturi nozzle 18, which sucks in the additive originating from the tank 12 from the line 11 and simultaneously releases it mixed into the line 16.
- an air line 19 is attached so that not only additives are sucked in from line 11, but also air via line 19. This has the advantage that the entire mixing device acts as a foam injector and via line 16 a water-foam mixture can be dispensed, which is flushed into the basin part 2.
- the advantages of admixing an additive from a tank with a relatively high capacity are that the urinal basin achieves a self-cleaning effect because the additive can be mixed with a relatively high concentration. At the same time, the urinal basin is sterilized and, due to the high dosage of the agent, a strong limestone-releasing and urine-releasing effect can also be achieved. This saves significant cleaning costs that would otherwise be incurred.

Abstract
Description
Gegenstand der Erfindung ist ein Urinal mit Spülung und Zusatzmittel mit den Merkmalen des Oberbegriffs von Anspruch 1.The invention relates to a urinal with flushing and additive with the features of the preamble of claim 1.
Bei derartigen Urinalen ist es bekannt, neben der Wasserspülung ein Zusatzmittel beizumischen. Dieses Zusatzmittel soll geruchsminderndn, reinigend, desinfizierend und kalk-und urinsteinlösend wirken.In urinals of this type, it is known to add an additive in addition to flushing the water. This additive is said to have an odor-reducing, cleaning, disinfecting and lime and urine-releasing effect.
Es ist bekannt, ein derartiges flüssiges Zusatzmittel über einen außerhalb und über dem Urinal-Becken angebrachten Kasten dem Spülwasser zuzuführen, wobei der Kasten an der Wand zu befestigen ist. Damit besteht aber der Nachteil eines erhöhten Platzbedarfs für die separate Anbringung des Tanks für das flüssige Zusatzmittel und zu dessen Dosierung. Wegen des Platzbedarfs hat der Tank nur ein verhältnismässig geringes Aufnahmevolumen für das flüssige Zusatzmittel.It is known to supply such a liquid additive to the rinsing water via a box attached outside and above the urinal basin, the box being to be fastened to the wall. However, there is the disadvantage of an increased space requirement for the separate attachment of the tank for the liquid additive and for its metering. Because of the space requirement, the tank has only a relatively small holding volume for the liquid additive.
Aus der Patentschrift US-3,445,865 ist ein gattungsgemäßer Urinal bekannt geworden, welches einen Zusatztank zur Beimischung desodorierender Zusatzmittel aufweist, welcher im wesentlichen ausserhalb an der Oberseite des Urinals angeordnet ist. Durch den auf diese Weise angebrachten Tank ist es leicht möglich, den Inhalt des Tanks zu kontrollieren und ggf. nachzufüllen.From the patent US-3,445,865 a generic urinal has become known, which has an additional tank for admixing deodorant additives, which is arranged essentially outside on the top of the urinal. The tank attached in this way makes it easy to check the contents of the tank and refill it if necessary.
Nachteilig aber ist, daß ein derartiger Aufsatztank den ästhetischen Eindruck des Urinals stört und daher nicht allzu groß ausgebildet werden sollte und weiterhin durch einen solchen Aufsatztank die Reinigung des Urinals erschwert wird.It is disadvantageous, however, that such an add-on tank disturbs the aesthetic impression of the urinal and should therefore not be made too large, and furthermore makes it difficult to clean the urinal by such an add-on tank.
Es ist auch bekannt, ein Zusatzmittel in Tablettenform lose in das Urinal einzugeben. Hierbei kann man aber das Zusatzmittel nicht genau dosieren, so daß man aus Sicherheitsgründen in der Regel überdosiert mit den bekannten nachteiligen Folgen für die Umweltbelastung.It is also known to add an additive in tablet form loosely to the urinal. Here, however, the additive cannot be metered exactly, so that for safety reasons one generally overdoses with the known disadvantageous consequences for the environmental impact.
Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Urinal mit Spülung und flüssigem Zusatzmittel so weiterzubilden, daß oben genannten Nachteilen begegnet wird und daß ohne weiteren Platzbedarf eine große Menge von Zusatzmittel betriebssicher in das Urinal eingetragen werden kann.The invention is therefore based on the object of developing a urinal with flushing and liquid additive in such a way that the above-mentioned disadvantages are countered and that a large amount of additive can be reliably introduced into the urinal without requiring additional space.
Zur Lösung der gestellten Aufgabe dient die technische Lehre des Patentanspruchs 1.The technical teaching of claim 1 serves to solve the problem.
Wesentlich hierbei ist, daß der Tank und das Mischteil in einem Freiraum im oberen Bereich an der Rückwand des Urinalbeckens angeordnet sind, wobei das Mischteil eine Venturidüse enthält. Diese Venturidüse saugt über eine Leitung Hauswasser und über eine weitere Leitung das aus dem Tank stammende Zusatzmittel an. Das mit dem Zusatzmittel vermischte Spülwasser wird dann dem Urinalbecken zugeführt.It is essential here that the tank and the mixing part are arranged in a free space in the upper region on the rear wall of the urinal basin, the mixing part containing a Venturi nozzle. This Venturi nozzle draws in domestic water via a line and the additive from the tank via a further line. The rinsing water mixed with the additive is then fed to the urinal basin.
Damit besteht der Vortzeil, daß eine betriebssichere, ohne Fremdenergie arbeitende Zumischvorrichtung gewährleistet ist.This provides the advantage that a reliable admixing device that works without external energy is guaranteed.
Nachdem das Urinal-Becken jenseits des Beckenteils einen relativ großen Freiraum aufweist, der notwendig ist, um im unteren Teil eine Syphon einzubauen, ergibt sich nun der Vorteil, daß der das Zusatzmittel aufnehmende Tank mit relativ großer Kapazität im Freiraum des Urinal-Beckens an dessen Rückseite eingebaut werden kann.After the urinal basin has a relatively large free space beyond the basin part, which is necessary to install a siphon in the lower part, there is now the advantage that the tank containing the additive has a relatively large capacity in the free space of the urinal basin at the bottom Back can be installed.
Der Tank kann leicht aufgefüllt werden, denn entsprechende Füllöffnungen kann man an der Oberseite des Urinalbeckens anbringen, wo sie leicht zugänglich sind.The tank can be easily refilled, because appropriate filling openings can be made on the top of the urinal basin, where they are easily accessible.
Bei dem bekannten an der Wand außerhalb des Urinal-Beckens angeordneten Zusatzeinrichtungen mußten diese so hoch über dem Urinal-Becken angebracht werden, daß das Auffüllen des Tanks schwierig war. Diese Schwierigkeit wird bei der vorliegenden Erfindung vermieden.With the known additional devices arranged on the wall outside the urinal basin, these had to be installed so high above the urinal basin that the refilling of the tank was difficult. This difficulty is avoided in the present invention.
Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentansprüche, sondern auch aus der Kombination der einzelnen Patentansprüche untereinander.The subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.
Alle in den Unterlagen - ggf. einschließlich der Zusammenfassung - offenbarten Angaben und Merkmale, insbesondere die in den Zeichnungen dargestellte räumliche Ausbildung werden als erfindungswesentlich beansprucht, soweit sie einzeln oder in Kombination gegenüber dem Stand der Technik neu sind.All of the information and features disclosed in the documents, possibly including the summary, in particular the spatial design shown in the drawings are claimed as essential to the invention, insofar as they are new to the prior art, individually or in combination.
Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellende Zeichnungen näher erläutert. Hierbei gehen aus den Zeichnungen und ihrer Beschreibung weitere wesentliche Merkmale und Vorteile der Erfindung hervor.In the following the invention is based on only one Execution path illustrating drawings explained in more detail. Further essential features and advantages of the invention emerge from the drawings and their description.

Gemäß Figur 1 besteht das Urinal-Becken 1 aus einem Beckenteil 2, an dessen vorderen Rand ein Ringkanal 6 angeordnet ist, der in das Becken hinein gerichtete Spüldüsen 7 aufweist. Diese Spüldüsen 7 können entweder punktförmig vorhanden sein oder es kann ein ringsum laufender Auslaufkanal sein, welcher als Spüldüse 7 wirkt.According to FIG. 1, the urinal basin 1 consists of a
Am Boden des Beckenteils 2 ist in an sich bekannter Weise ein Auslauf 8 vorgesehen, an dem ein Syphon 9 angeschlossen ist.At the bottom of the
Die Rückseite des Urinal-Beckens 1 weist einen Freiraum 3 auf, in den ein Tank 12 mit relativ hoher Kapazität zur Aufnahme eines Zusatzmittels eingebaut ist. Dieser Tank 12 wird von einer oberen Einfüllöffnung 26 über eine Leitung 27 aufgefüllt. Er weist eine Entnahmeleitung 11 auf, die in ein Mischteil 10 mündet.The rear of the urinal basin 1 has a
Das Hauswasser gelangt über den Wasserzulauf 15 und ein Eckventil 14 in die Leitung 13, die ebenfalls in das Mischteil 10 mündet. Am Ausgang des Mischteils 10 ist die Leitung 16 angeschlossen, die das Spülwasser vermengt mit dem Zusatzmittel enthält. Diese Leitung 16 mündet in eine Ausnehmung 17, im oberen Teil des Ringkanals 6, so daß mit Einlauf in diese Ausnehmung 17 das mit dem Zusatzmittel vermischte Spülwasser über den gesamten Ringkanal 6 verteilt wird und über die gesamte Länge des Ringkanals über die Spüldüsen 7 in das Beckenteil 2 ausläuft.The domestic water reaches the
Der Spülvorgang kann hierbei durch eine Spültaste ausgelöst werden, die nicht näher dargestellt ist. Der Spültaste ist ein Magnetventil 5 zugeordnet, welches von einem Elektronikteil 4 angesteuert wird.The rinsing process can be triggered by a rinsing button, which is not shown in detail. A

Es kann zusätzlich vorgesehen sein, daß eine Luftleitung 19 angebracht ist, so daß nicht nur Zusatzmittel aus der Leitung 11 angesaugt werden, sondern zusätzlich Luft über die Leitung 19. Damit besteht der Vorteil, daß die gesamte Mischvorrichtung als Schauminjektor wirkt und über die Leitung 16 ein Wasser-Schaumgemisch abgegeben werden kann, welches fein verteilt im Beckenteil 2 eingespült wird.It can also be provided that an
Die Vorteile der Zumischung eines Zusatzmittels aus einem Tank mit relativ hoher Kapazität liegen darin, daß das Urinal-Becken einen Selbstreinigungseffekt erzielt, weil das Zusatzmittel mit relativ hoher Konzentration gemischt werden kann. Gleichzeitig wird das Urinal-Becken sterilisiert und wegen der hohen Zudosierungsmöglichkeit des Mittels kann gleichzeitig auch ein starker kalksteinlösender und urinsteinlösender Effekt erzielt werden. Es werden damit wesentliche Reinigungskosten eingespart, die andernfalls anfallen würden.The advantages of admixing an additive from a tank with a relatively high capacity are that the urinal basin achieves a self-cleaning effect because the additive can be mixed with a relatively high concentration. At the same time, the urinal basin is sterilized and, due to the high dosage of the agent, a strong limestone-releasing and urine-releasing effect can also be achieved.
