Definitions
- the invention relates to an overflow device in particular for a washing area in the sanitary area according to the preamble of claim 1.
- the device for collecting a liquid which is designed, for example, in the form of a washstand, has an upper opening through which the maximum fill level is determined. As soon as the liquid accumulated in the collecting device, such as water, exceeds the maximum fill level, further water flowing into the collecting device flows into a drain via the upper opening, so that the collecting device ultimately does not overflow and thus, for example, a bathroom is not under water can put.
- So-called hidden overflows in which long tubes are used, are also known in sanitary practice. These are relatively dirty. The heat builds up in the tubes, thereby creating an ideal breeding climate for harmful germs. Also, the water accumulated in the tubes usually has a direct flow connection to the water in the wash basin, so that fresh water in the wash basin can also come into contact with the germs in the tube system. The water then has direct contact with the aforementioned biofilm in the event of a covered overflow. Washing infants or old people with water from such washbasins can be correspondingly problematic.
- An overflow device of the type mentioned is also from the EP 2 918 739 A1 known.
- This device has a pressure sensor that detects the height of the water level, an electronic measuring and control device to which the measurement signals of the pressure sensor are transmitted, and an actuator for opening and / or closing a floor drain valve, the actuator being separated from the measuring and control device in Dependence of the water level detected by the pressure sensor is controlled.
- the invention has for its object to provide an overflow device that is simpler and less problematic to handle.
- the overflow device which can be used in particular for a washing area in the sanitary area, has a device for collecting a liquid and a device by means of which an overflow of the collecting device is prevented, the device for preventing overflow of the collecting device having a valve which consists of a an outflow of the liquid from the collection device enabling release position can be moved into a blocking position preventing the outflow and vice versa, and the valve moves automatically from its blocking position into its release position when the maximum filling level of the collection device is exceeded.
- an “automatic process” is understood to mean a process of the valve without further aids, such as pressure sensors, electrical or electronic measuring and control devices, actuators or also mechanical aids, such as springs.
- valve alone has the function of an overflow protection in the sense of a double function and other elements, such as overflow openings in the collecting device, connecting lines from the overflow opening to the drain, hidden overflows or the aforementioned electrical, electronic or mechanical aids, are complete can be omitted.
- the overflow device according to the invention is thus constructed on the one hand simply and safely, on the other hand it can be handled very easily with regard to the germs which are partially present in the further elements. Since these other elements are omitted, no dirt residues, biofilms or germs can form in them.
- the valve can be moved from its blocking position into its release position by forces acting on it from the hydrostatic pressure of the liquid column, buoyancy and weight.
- the level of the hydrostatic pressure in relation to the buoyancy counteracting the former is therefore the trigger for transferring the valve from its blocking position into its release position or for leaving it in its blocking position. It follows from this that the liquid in the collecting device monitors itself to a certain extent. If the hydrostatic pressure rises above a threshold value, this presses the valve against the lift from its blocking position in its release position. As long as the hydrostatic pressure is below the threshold value, the valve remains in its blocking position.
- the valve has a round, oval, elliptical or a rectangular, in particular square, cross-sectional area, the valve having an upper sealing section, which preferably seals the collecting device in a linear manner in the blocking position.
- the collecting device has a container, preferably a siphon, filled with liquid and at least partially accommodating the valve, the container, preferably a siphon, preferably being arranged directly below the collecting device.
- the siphon can also have the function of accommodating the valve.
- Siphons designed in the usual way are arranged significantly lower than the siphon according to the invention.
- short paths can be implemented for the liquid flowing out of the collecting device, so that the overflow device according to the invention can ultimately also be produced very inexpensively.
- the siphon according to the invention thus also blocks significantly less drawer space below the washing area, such as below the washstand, so that expensive siphon cutouts can be avoided or eliminated in such drawers.
- valve in the container filled with liquid preferably a siphon
- liquid preferably a siphon
- buoyant forces acting on the valve It follows that the valve is at least partially immersed in the liquid in the container, preferably a siphon, and counteracted by gravity, e.g. upwards, is pressed into its locked position or is acted upon.
- an adjustment device by means of which the valve arranged in the container, preferably a siphon, can be moved into its release position. This ensures that the valve is replaced by a Actuation of the adjusting device can be moved with the force of gravity, ie downwards, so that the aforementioned buoyancy forces can no longer hold the valve in its blocking position.
- the liquid such as water
- the collecting device such as the washstand. The water cannot build up in the collecting device.
- the valve automatically moves from its release position back into its blocking position when the level of the collecting device falls below the maximum filling level and the adjusting device does not act or is not actuated.
- the overflow device according to the invention can thus also be used to maintain or regulate a desired fill level in a collecting device into which liquid continuously flows.
- the invention relates generally to an overflow device.
- the invention relates to a washing area in the sanitary area, such as a washstand, also called a sink, or a bathtub.
- a washstand also called a sink
- a bathtub In the 1 to 3 are a cut symbolize hatching for simplicity and better clarity omitted.
- FIGS 1 to 3 An overflow device 1 for a washing area 2 in the sanitary area is shown schematically in a partial vertical section in various working positions in FIGS 1 to 3 shown.
- Fig. 1 A first working position is shown, in which the overflow device 1 allows liquid, such as water, to flow out of the washstand 2.
- the overflow device 1 has a device 3 for collecting the liquid 5 flowing, for example, from a tap 4, such as a mixer tap, also called a mixer tap.
- a tap 4 such as a mixer tap, also called a mixer tap.
- the device 3 for collecting the liquid is briefly called a collecting device 3.
- the collecting device 3 is, as mentioned above, for example a basin or a tub.
- the overflow device 1 has a device 6 by means of which the collecting device 3 is prevented from overflowing.
- the device 6 for preventing the overflow of the collecting device 3 has a valve 7. This valve can be moved from a release position which enables the liquid 5 to flow away from the collecting device 3 into a blocking position preventing the flow and vice versa.
- the release position of the valve 7 is for example in the Fig. 1 and 3rd , the blocking position of the valve 7 in Fig. 2 shown.
- the washing area 2 with its collecting device 3 is fastened to a wall 10 in a manner not shown in detail.
- the collecting device 3 preferably has at its lowest point a drain opening 11 which is connected to a drain (not shown in more detail) via a siphon 12 and a pipe 13 leading to the wall 10.
- Fig. 1 the overflow device 1 is shown in its first working position, which allows liquid to flow out of the collecting device 3.
- the liquid 5 flowing into the collecting device 3 via the tap 4 can flow along the arrows A through the drain opening 11, the siphon 12 and pipeline 13 to the drain, not shown in any more detail.
- the liquid 5 is therefore not accumulated in the collecting device 3 in this working position.
- This working position of the overflow device 1 is used, for example, for washing hands.
- the valve 7 moves when a maximum fill level 14 is exceeded (see Fig. 2 and 3rd ) of the collecting device 3 automatically from its blocking position into its release position, so that excess liquid can flow out of the collecting device.
- the invention is based on the general idea that the valve 7 can be moved from its blocking position into its release position and vice versa solely by the hydrostatic pressure of the liquid column 15 above the valve 7, without additional aids for switching the valve being required. This applies in particular when the hydrostatic pressure of the liquid column 15 located above the valve 7 exceeds a certain threshold value, which is also determined by the lift of the valve. At this point in time, the valve opens so that liquid located above the maximum fill level 15 flows out of the collecting device 3.
- the valve 7 has a round, oval, elliptical or a rectangular, in particular square, cross-sectional area 16.
- the valve 7 also has an upper sealing section 17 which, in the blocking position of the valve 7, seals the collecting device 3 linearly on an annular sealing lip 20 seated in the drain opening 11, as shown in FIG Fig. 2 is indicated.
- the collecting device 3 In the in Fig. 2 shown second working position of the overflow device 1, the collecting device 3 is thus sealed, so that liquid 5 flowing into the collecting device 3 collects in the collecting device 3 and builds up in this in the direction of the arrow B pointing upward.
- a container filled with liquid and at least partially accommodating the valve 7, preferably the siphon 12, is arranged directly below the collecting device 3.
- the container, preferably siphon 12, is thus fluidically seated connected immediately below the drain opening 11 of the collecting device 3.
- the siphon 12, as is customary and in the 1 to 3 indicated is filled with the liquid 5.
- the container filled with liquid and at least partially accommodating the valve is not necessarily designed as a siphon.
- the functions "overflow” and "siphon" can also be separated, for example for reasons of space, according to an embodiment that is not shown in detail.
- the siphon can also be arranged leaving a distance below the collecting device, that is, it does not necessarily have to be arranged directly below the collecting device.
- Fig. 2 further clarifies that the valve 7 in the container filled with liquid 5, namely the siphon 12, is preloaded into its blocking position by buoyant forces acting on the valve 7.
- the valve therefore also functions as a float.
- the entirety of the forces acting on the valve 7, here in particular the hydrostatic pressure of the liquid column, buoyancy and weight forces, have the effect that the valve 7, provided that the buoyancy exceeds the pressure of the liquid column and the weight force, seals the collecting device 3 in it Locked position.
- This blocking position of the valve 7 thus corresponds to the second working position of the overflow device 1; this remains maintained until the fill level accumulated in the collecting device 3 has reached and exceeded the maximum fill level 14.
- an adjusting device 21 is provided, by means of which the valve 7 arranged in the container, preferably siphon 12, can be moved into its release position.
- the adjusting device 21 thus causes the valve 7 to be moved from its blocking position into its release position. Since the valve, as mentioned above, is preloaded into its blocking position, the adjusting device 21 effects an adjustment of the valve seated in the container, preferably siphon 12, against its buoyancy forces, so that the valve is in its lower release position and no longer in its preloaded position upper locked position.
- the adjusting device 21 is according to the in the 1 to 3
- a U-shaped magnet 22 for example a permanent magnet, which, if it is close enough to the magnetic valve 7, pulls it downward against buoyancy forces acting on the valve.
- Fig. 1 is the adjusting device 21 in its actuated, ie active position, while the adjusting device 21 is in the Fig. 2 and 3rd is in its non-actuated, ie passive position.
- the adjustment device 21 is in the Fig. 2 and 3rd moved away from the siphon 12 and thus from the valve 7 while they are in accordance with Fig. 1 is located directly on the siphon 12 and can thus act on the valve 7.
- the valve 7 automatically moves from its release position into its blocking position when the maximum fill level 14 of the collecting device 3 is undershot and the passive adjusting device 21 does not act.
- the overflow device 1 according to the invention can also be used as a device for regulating the fill level, by means of which only excess liquid is drained off (see arrow C in Fig. 3 ) and almost a constant fill level is established in the collecting device. In the latter case of a liquid flowing into a pent-up collecting device, the valve 7 oscillates in the direction of the double arrow D automatically and therefore automatically between its release and blocking position.
- adjustment device can also be designed in some other way, in particular mechanically, for example via a linkage or a cable pull.
- the valve opens as soon as the weight of the liquid column or the hydrostatic pressure of the liquid column together with the weight of the valve is greater than the buoyancy of the valve designed as a floating body in the container, preferably a siphon. Conversely, if the buoyancy is greater than the weight of the liquid column and the weight of the valve, the latter closes. The resulting force acting on the valve thus causes the valve to be transferred either to its blocking position or to its release position

Description
Die Erfindung betrifft eine Überlaufvorrichtung insbesondere für einen Waschplatz im Sanitärbereich nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an overflow device in particular for a washing area in the sanitary area according to the preamble of
Eine solche Überlaufvorrichtung ist aus der Praxis bekannt. Bei dieser Überlaufvorrichtung weist die Einrichtung zum Auffangen einer Flüssigkeit, welche beispielsweise in Form Waschtisches ausgebildet ist, eine obere Öffnung auf, durch die die maximale Füllstandshöhe festgelegt ist. Sobald die in der Auffangeinrichtung aufgestaute Flüssigkeit, wie zum Beispiel Wasser, die maximale Füllstandshöhe überschreitet, fließt weiteres, in die Auffangeinrichtung einströmendes Wasser über die obere Öffnung in einen Abfluss ab, so dass die Auffangeinrichtung letztlich nicht überlaufen und damit beispielsweise ein Badezimmer nicht unter Wasser setzen kann.Such an overflow device is known from practice. In this overflow device, the device for collecting a liquid, which is designed, for example, in the form of a washstand, has an upper opening through which the maximum fill level is determined. As soon as the liquid accumulated in the collecting device, such as water, exceeds the maximum fill level, further water flowing into the collecting device flows into a drain via the upper opening, so that the collecting device ultimately does not overflow and thus, for example, a bathroom is not under water can put.
Durch die mit dem Abfluss verbundene obere Öffnung der Auffangeinrichtung können sich allerdings unangenehme Gerüche ausbreiten. Im Übrigen verschmutzen derartige Öffnungen und die Verbindungsleitung von der Öffnung zum Abfluss relativ schnell, so dass sich in diesem Bereich leicht Bakterien bilden können. Mit starken Reinigungsmitteln lassen sich schlechte Gerüche zwar überdecken, allerdings bleibt der oft nur schwer zugängliche Bakterienherd häufig bestehen. Ferner können sich in dem vorgenannten Bereich sogenannte Biofilme bilden, die letztlich mehrere Schichten aufweisen können, in denen weitere gesundheitsschädliche Spezies sich ansiedeln können.However, unpleasant smells can spread through the upper opening of the collecting device connected to the drain. Moreover, such openings and the connecting line from the opening to the drain get dirty relatively quickly, so that bacteria can easily form in this area. With strong cleaning agents, bad smells can be masked, but the often difficult to access bacterial source often remains. Furthermore, in the so-called area form so-called biofilms, which can ultimately have multiple layers in which other harmful species can settle.
Außerdem können bei einem starken Verschmutzungsgrad im Überlaufkanal gesundheitsschädliche Aerosole in die Atemluft einer beispielsweise einen Waschtisch benutzenden Person gelangen.In addition, if the degree of contamination in the overflow channel is severe, harmful aerosols can get into the breathing air of a person using a washstand, for example.
Bekannt sind in der Sanitärpraxis ferner sogenannte verdeckte Überläufe, bei denen lange Röhren zur Anwendung kommen. Diese verschmutzen relativ stark. In den Röhren staut sich die Wärme und bildet dadurch ein ideales Brutklima für gesundheitsschädliche Keime. Auch hat das in den Röhren aufgestaute Wasser üblicherweise eine direkte Strömungsverbindung zum Wasser im Waschtisch, so dass auch frisches, im Waschtisch befindliches Wasser mit den Keimen im Röhrensystem in Verbindung treten kann. Das Wasser hat dann bei einem verdeckten Überlauf direkten Kontakt zu dem vorgenannten Biofilm. Entsprechend problematisch kann das Waschen von Säuglingen oder von alten Menschen mit Wasser aus derartigen Waschtischen sein.So-called hidden overflows, in which long tubes are used, are also known in sanitary practice. These are relatively dirty. The heat builds up in the tubes, thereby creating an ideal breeding climate for harmful germs. Also, the water accumulated in the tubes usually has a direct flow connection to the water in the wash basin, so that fresh water in the wash basin can also come into contact with the germs in the tube system. The water then has direct contact with the aforementioned biofilm in the event of a covered overflow. Washing infants or old people with water from such washbasins can be correspondingly problematic.
Eine Überlaufvorrichtung der eingangs erwähnten Art ist ferner aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Überlaufvorrichtung zu schaffen, die einfacher aufgebaut und unproblematischer handhabbar ist.The invention has for its object to provide an overflow device that is simpler and less problematic to handle.
Diese Aufgabe wird erfindungsgemäß durch eine Überlaufvorrichtung der oben genannten Art mit den in Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.This object is achieved by an overflow device of the type mentioned above with the features specified in
Die Überlaufvorrichtung, welche insbesondere für einen Waschplatz im Sanitärbereich eingesetzt werden kann, hat eine Einrichtung zum Auffangen einer Flüssigkeit und eine Einrichtung, mittels der ein Überlaufen der Auffangeinrichtung verhindert ist, wobei die Einrichtung zum Verhindern des Überlaufens der Auffangeinrichtung ein Ventil aufweist, das aus einer ein Abfließen der Flüssigkeit aus der Auffangeinrichtung ermöglichenden Freigabestellung in eine das Abfließen unterbindende Sperrstellung und umgekehrt bewegbar ist, und das Ventil bei Überschreiten der maximalen Füllstandshöhe der Auffangeinrichtung selbsttätig aus seiner Sperr- in seine Freigabestellung verfährt. Unter einem "selbsttätigen Verfahren" wird erfindungsgemäß ein Verfahren des Ventils ohne weitere Hilfsmittel, wie Drucksensoren, elektrische oder elektronische Mess- und Steuerungseinrichtungen, Stellglieder oder auch mechanische Hilfsmittel, wie zum Beispiel Federn, verstanden. Vorteilhaft ist dabei, dass allein das Ventil im Sinne einer Doppelfunktion gleichzeitig die Funktion eines Überlaufschutzes hat und weitere Elemente, wie zum Beispiel Überlauföffnungen in der Auffangeinrichtung, Verbindungsleitungen von der Überlauföffnung zum Abfluss, verdeckte Überläufe oder die vorerwähnten elektrischen, elektronischen oder mechanischen Hilfsmittel, vollständig entfallen können. Damit ist die erfindungsgemäße Überlaufvorrichtung auf der einen Seite einfach und sicher aufgebaut, auf der anderen Seite, was die teilweise in den weiteren Elementen befindlichen Keime betrifft, sehr unproblematisch handhabbar. Da diese weiteren Elemente entfallen, können sich darin auch keine Schmutzreste, Biofilme oder Keime bilden.The overflow device, which can be used in particular for a washing area in the sanitary area, has a device for collecting a liquid and a device by means of which an overflow of the collecting device is prevented, the device for preventing overflow of the collecting device having a valve which consists of a an outflow of the liquid from the collection device enabling release position can be moved into a blocking position preventing the outflow and vice versa, and the valve moves automatically from its blocking position into its release position when the maximum filling level of the collection device is exceeded. According to the invention, an “automatic process” is understood to mean a process of the valve without further aids, such as pressure sensors, electrical or electronic measuring and control devices, actuators or also mechanical aids, such as springs. It is advantageous that the valve alone has the function of an overflow protection in the sense of a double function and other elements, such as overflow openings in the collecting device, connecting lines from the overflow opening to the drain, hidden overflows or the aforementioned electrical, electronic or mechanical aids, are complete can be omitted. The overflow device according to the invention is thus constructed on the one hand simply and safely, on the other hand it can be handled very easily with regard to the germs which are partially present in the further elements. Since these other elements are omitted, no dirt residues, biofilms or germs can form in them.
Gemäß einer besonders bevorzugten Ausführungsform ist das Ventil durch an ihm angreifenden Kräfte aus hydrostatischem Druck der Flüssigkeitssäule, Auftrieb und Gewicht aus seiner Sperr- in seine Freigabestellung überführbar. Die Höhe des hydrostatischen Druckes im Verhältnis zu dem Ersterem entgegen wirkenden Auftrieb ist also der Auslöser dafür, das Ventil aus seiner Sperr- in seine Freigabestellung zu überführen oder in seiner Sperrstellung zu belassen. Daraus folgt, dass sich die in der Auffangeinrichtung befindliche Flüssigkeit gewissermaßen selbst überwacht. Steigt der hydrostatische Druck über einen Schwellenwert an, drückt dieser das Ventil gegen den Auftrieb aus dessen Sperr- in dessen Freigabestellung. Solange der hydrostatische Druck unterhalb des Schwellenwertes liegt, verharrt das Ventil in seiner Sperrstellung.According to a particularly preferred embodiment, the valve can be moved from its blocking position into its release position by forces acting on it from the hydrostatic pressure of the liquid column, buoyancy and weight. The level of the hydrostatic pressure in relation to the buoyancy counteracting the former is therefore the trigger for transferring the valve from its blocking position into its release position or for leaving it in its blocking position. It follows from this that the liquid in the collecting device monitors itself to a certain extent. If the hydrostatic pressure rises above a threshold value, this presses the valve against the lift from its blocking position in its release position. As long as the hydrostatic pressure is below the threshold value, the valve remains in its blocking position.
Gemäß einer Weiterbildung weist das Ventil eine runde, ovale, elliptische oder eine rechteckige, insbesondere quadratische, Querschnittsfläche auf, wobei das Ventil einen oberen Dichtabschnitt hat, der die Auffangeinrichtung in der Sperrstellung vorzugsweise linienförmig abdichtet. Dadurch ist sichergestellt, dass das Ventil aufgrund der an ihm angreifenden Kräfte in bestimmten, klar vordefinierten Zuständen schaltet, d.h. aus seiner Sperr- in seine Freigabestellung und umgekehrt verfährt und unklare oder weitgefasste Schaltbereiche weitgehend verhindert sind.According to a further development, the valve has a round, oval, elliptical or a rectangular, in particular square, cross-sectional area, the valve having an upper sealing section, which preferably seals the collecting device in a linear manner in the blocking position. This ensures that the valve switches in certain, clearly predefined states due to the forces acting on it, i.e. moved from its blocking position into its release position and vice versa and unclear or wide switching ranges are largely prevented.
Gemäß einer anderen Weiterbildung der Erfindung weist die Auffangeinrichtung einen mit Flüssigkeit gefüllten, das Ventil zumindest teilweise aufnehmenden Behälter, vorzugsweise Siphon, auf, wobei der Behälter, vorzugsweise Siphon, vorzugsweise unmittelbar unterhalb der Auffangeinrichtung angeordnet ist. Im Sinne einer Doppelfunktion kann damit der Siphon zusätzlich zu seiner Funktion der Bildung eines Geruchsverschlusses auch die Funktion haben, das Ventil aufzunehmen. In üblicher Weise gestaltete Siphons sind deutlich tiefer als der erfindungsgemäße Siphon angeordnet. Dadurch können für die aus der Auffangeinrichtung abfließende Flüssigkeit kurze Wege realisiert werden, so dass die erfindungsgemäße Überlaufvorrichtung letztlich auch sehr kostengünstig herstellbar ist. Der erfindungsgemäße Siphon versperrt damit ferner deutlich weniger Schubladenraum unterhalb des Waschplatzes, wie zum Beispiel unterhalb des Waschtisches, so dass in solchen Schubladen teure Siphonausschnitte vermieden werden oder entfallen können.According to another development of the invention, the collecting device has a container, preferably a siphon, filled with liquid and at least partially accommodating the valve, the container, preferably a siphon, preferably being arranged directly below the collecting device. In the sense of a double function, in addition to its function of forming an odor trap, the siphon can also have the function of accommodating the valve. Siphons designed in the usual way are arranged significantly lower than the siphon according to the invention. As a result, short paths can be implemented for the liquid flowing out of the collecting device, so that the overflow device according to the invention can ultimately also be produced very inexpensively. The siphon according to the invention thus also blocks significantly less drawer space below the washing area, such as below the washstand, so that expensive siphon cutouts can be avoided or eliminated in such drawers.
Vorteilhafterweise ist das Ventil in dem mit Flüssigkeit aufgefüllten Behälter, vorzugsweise Siphon, durch auf das Ventil einwirkende Auftriebskräfte in seine Sperrstellung vorbelastet. Daraus folgt, dass das Ventil zumindest teilweise in die im Behälter, vorzugsweise Siphon, befindliche Flüssigkeit eintaucht und durch Auftriebskräfte entgegen der Schwerkraft, d.h. nach oben hin, in seine Sperrstellung gedrückt wird bzw. beaufschlagt ist.The valve in the container filled with liquid, preferably a siphon, is advantageously preloaded into its blocking position by buoyant forces acting on the valve. It follows that the valve is at least partially immersed in the liquid in the container, preferably a siphon, and counteracted by gravity, e.g. upwards, is pressed into its locked position or is acted upon.
Gemäß einer anderen Weiterbildung ist eine Verstelleinrichtung vorgesehen, mittels der das im Behälter, vorzugsweise Siphon, angeordnete Ventil in seine Freigabestellung überführbar ist. Dadurch ist sichergestellt, dass das Ventil durch ein Betätigen der Verstelleinrichtung mit der Schwerkraft, d.h. nach unten hin, bewegt werden kann, so dass die vorerwähnten Auftriebskräfte das Ventil nicht länger in dessen Sperrstellung halten können. In der durch die Verstelleinrichtung herbeigeführten Freigabestellung kann somit die Flüssigkeit, wie zum Beispiel Wasser, aus der Auffangeinrichtung, wie zum Beispiel dem Waschtisch, abfließen. Das Wasser kann sich in der Auffangeinrichtung nicht aufstauen.According to another development, an adjustment device is provided, by means of which the valve arranged in the container, preferably a siphon, can be moved into its release position. This ensures that the valve is replaced by a Actuation of the adjusting device can be moved with the force of gravity, ie downwards, so that the aforementioned buoyancy forces can no longer hold the valve in its blocking position. In the release position brought about by the adjusting device, the liquid, such as water, can thus flow out of the collecting device, such as the washstand. The water cannot build up in the collecting device.
Gemäß noch einer Weiterbildung verfährt das Ventil bei Unterschreiten der maximalen Füllstandshöhe der Auffangeinrichtung und nicht einwirkender bzw. nicht betätigter Verstelleinrichtung selbsttätig aus seiner Freigabe- zurück in seine Sperrstellung. Damit kann die erfindungsgemäße Überlaufvorrichtung auch dazu eingesetzt werden, einen gewünschten Füllstand in einer Auffangeinrichtung, in die laufend Flüssigkeit nachfließt, zu halten bzw. zu regulieren.According to a further development, the valve automatically moves from its release position back into its blocking position when the level of the collecting device falls below the maximum filling level and the adjusting device does not act or is not actuated. The overflow device according to the invention can thus also be used to maintain or regulate a desired fill level in a collecting device into which liquid continuously flows.
Ausführungsbeispiele des Erfindungsgegenstandes werden nachfolgend anhand der Zeichnung näher erläutert, wobei alle beschriebenen und/oder bildlich dargestellten Merkmale für sich oder in beliebiger Kombination den Gegenstand der vorliegenden Erfindung unabhängig von ihrer Zusammenfassung in den Ansprüchen oder deren Rückbeziehung bilden.

Die Erfindung bezieht sich allgemein auf eine Überlaufvorrichtung. Insbesondere aber nicht ausschließlich bezieht sich die Erfindung auf einen Waschplatz im Sanitärbereich, wie zum Beispiel einen Waschtisch, auch Waschbecken genannt, oder eine Badewanne. In den
Eine Überlaufvorrichtung 1 für einen Waschplatz 2 im Sanitärbereich ist schematisch in einem teilweisen Vertikalschnitt in verschiedenen Arbeitsstellungen in den
Die Überlaufvorrichtung 1 hat eine Einrichtung 3 zum Auffangen der beispielsweise aus einem Hahn 4, wie einer Mischbatterie, auch Mischarmatur genannt, strömenden Flüssigkeit 5. Nachfolgend wird die Einrichtung 3 zum Auffangen der Flüssigkeit kurz Auffangeinrichtung 3 genannt. Die Auffangeinrichtung 3 ist, wie zuvor erwähnt, beispielsweise ein Becken oder eine Wanne.The
Außerdem hat die Überlaufvorrichtung 1 eine Einrichtung 6, mittels der ein Überlaufen der Auffangeinrichtung 3 verhindert ist. Die Einrichtung 6 zum Verhindern des Überlaufens der Auffangeinrichtung 3 weist ein Ventil 7 auf. Dieses Ventil ist aus einer ein Abfließen der Flüssigkeit 5 aus der Auffangeinrichtung 3 ermöglichenden Freigabestellung in eine das Abfließen unterbindende Sperrstellung und umgekehrt bewegbar. Die Freigabestellung des Ventils 7 ist beispielsweise in den
Der Waschplatz 2 mit seiner Auffangeinrichtung 3 ist auf nicht näher gezeigte Weise an einer Wand 10 befestigt. Die Auffangeinrichtung 3 hat vorzugsweise an ihrer tiefsten Stelle eine Abflussöffnung 11, welche über einen Siphon 12 und eine zur Wand 10 führende Rohrleitung 13 mit einem nicht näher gezeigten Abfluss verbunden ist.The
In
Erfindungsgemäß verfährt das Ventil 7 bei Überschreiten einer maximalen Füllstandshöhe 14 (siehe
Das Ventil 7 weist eine runde, ovale, elliptische oder eine rechteckige, insbesondere quadratische, Querschnittsfläche 16 auf. Das Ventil 7 hat ferner einen oberen Dichtabschnitt 17, der die Auffangeinrichtung 3 in der Sperrstellung des Ventils 7 linienförmig an einer in der Abflussöffnung 11 sitzenden ringförmigen Dichtlippe 20 abdichtet, wie dies in
Gemäß einer in den
Wie in den
Die Verstelleinrichtung 21 ist gemäß dem in den
Es wird darauf hingewiesen, dass das Ventil 7 bei Unterschreiten der maximalen Füllstandshöhe 14 der Auffangeinrichtung 3 und nicht einwirkender, d.h. passiver Verstelleinrichtung 21 selbsttätig aus seiner Freigabe- in seine Sperrstellung verfährt. Insofern kann die erfindungsgemäße Überlaufvorrichtung 1 auch als Einrichtung zum Regulieren der Füllstandshöhe eingesetzt werden, mittels welcher lediglich überschüssige Flüssigkeit abgelassen wird (siehe Pfeil C in
Es ist klar, dass die Verstelleinrichtung auch anderweitig, insbesondere mechanisch, beispielsweise über ein Gestänge oder einen Seilzug, ausgebildet sein kann.It is clear that the adjustment device can also be designed in some other way, in particular mechanically, for example via a linkage or a cable pull.
In der in
Letztlich öffnet das Ventil, sobald das Gewicht der Flüssigkeitssäule bzw. der hydrostatische Druck der Flüssigkeitssäule zusammen mit dem Gewicht des Ventils größer ist als der Auftrieb des als Schwimmkörper ausgebildeten Ventils im Behälter, vorzugsweise Siphon. Im umgekehrten Fall, wenn also die Auftriebskraft größer als das Gewicht der Flüssigkeitssäule und das Gewicht des Ventils ist, schließt letzteres. Die an dem Ventil angreifende resultierende Kraft bewirkt also ein Überführen des Ventils entweder dessen Sperr- oder in dessen FreigabestellungUltimately, the valve opens as soon as the weight of the liquid column or the hydrostatic pressure of the liquid column together with the weight of the valve is greater than the buoyancy of the valve designed as a floating body in the container, preferably a siphon. Conversely, if the buoyancy is greater than the weight of the liquid column and the weight of the valve, the latter closes. The resulting force acting on the valve thus causes the valve to be transferred either to its blocking position or to its release position
Damit ist eine Überlaufvorrichtung geschaffen, die einfacher aufgebaut und unproblematisch handhabbar ist.This creates an overflow device that is simpler in construction and unproblematic to handle.
