Abstract

The invention relates to a cleaning device for a piping system of a whirlpool tub where one or more outlet valves supply water and/or air into the interior of the tub. The outlet valves branch off from a cleaning-fluid circulation system using a delivery pump to circulate the cleaning fluid. When the cleaning fluid is circulated the outlet valves are in a closed position, receiving a flow of the cleaning fluid, but preventing the issuance of the cleaning fluid into the tub interior. The outlet valve has a water-supply line connecting into a water-distribution chamber disposed in a valve body, from which a water-outlet channel branches toward the tub interior. The water-outlet channel guides, in a watertight and axially movable manner, a sealing member passing through the water-distribution chamber. The sealing member has a smaller cross section than the water-distribution chamber, and an end face of the sealing remember, when in a closed position, is precisely flush with or bulges just slightly beyond an adjoining end face of the valve body.

Description

Die Erfindung bezieht sich auf eine Reinigungseinrichtung für das Rohrleitungssystem einer Whirlpool-Wanne mit einem oder mehreren Austrittsventilen für die Zufuhr von Wasser und/oder Luft in den Innenraum der Wanne, welche von einem eine Förderpumpe aufweisenden, von dem Wanneninnenraum unabhängigen Kreislaufsystem für die Reinigungsflüssigkeit abzweigen und mit einem Verschlußkörper versehen sind, um die Austrittsventile in eine gegenüber dem Wanneninnenraum flüssigkeitsdichte Verschlußstellung zur Durchströmung von Reinigungsflüssigkeit zu bringen.The invention relates to a cleaning device for the piping system of a whirlpool tub with one or more outlet valves for supplying water and / or air into the interior of the tub, which branch off from a circulation system for the cleaning liquid that has a feed pump and is independent of the tub interior and are provided with a closure body in order to bring the outlet valves into a closed position, which is liquid-tight with respect to the tub interior, for the flow of cleaning fluid.

Aus der DE-A-3 447 772 ist eine Vorrichtung zum Desinfizieren bzw. Reinigen für ein Rohrleitungssystem einer Whirlpool-Wanne bekannt, das mit einem oder mehreren Austrittsventilen für die Zufuhr von Wasser und/oder Luft in den Innenraum der Wanne versehen ist. Dabei zweigen die Austrittsventile von einem eine Förderpumpe aufweisenden, von dem Wanneninnenraum unabhängigen Kreislaufsystem für die Reinigungsflüssigkeit ab und sind in der gegenüber dem Wanneninnenraum flüssigkeitsdichten Verschlußstelle zur Durchströmung von Reinigungsflüssigkeit ausgebildet. Als Mittel für die gegenüber dem Wanneninnenraum flüssigkeitsdichte Verschlußstellung der Austrittsdüsen sind Abdeck- oder Absperreinrichtungen vorgesehen. So soll in einem Falle, bei dem die Badewanne benachbart jeder Düse über einen Auslauf verfügt, der mit der Einlaßsaugseite einer Pumpe verbunden ist, durch welche im Betrieb und während des Badens das zirkulierende Wasser durch die Pumpe abgesaugt wird, die Abdeckeinrichtung dazu dienen, jede Düse und den zugeordneten Auslaß aus dem Innenraum der Badewanne abzusperren, um während der Desinfektion die durch die Düse zirkulierende Desinfektionslösung durch den zugeordneten Auslaß zuzuführen. In einem anderen Fall, bei dem jeder Düse eine Luftzuführungsanordnung zugeordnet ist, sollen die Mittel ein über das Ende jeder Düse eng passendes Abdeckelement, wie beispielsweise eine Einrastkappe oder eine Aufschraubkappe, aufweisen, so daß die zirkulierende Desinfektionslösung der Düse durch die zugeordnete Luftzuführungsanordnung geführt wird. Mit dieser bekannten Einrichtung ist zwar eine Reinigung des Rohrleitungssystems einer Whirlpool-Wanne möglich, sie kann dagegen nicht verhindern, daß in den Austrittsventilen unmittelbar oberhalb des Austrittsventils Hohlräume verbleiben, in welchen Restwasser stehen bleibt und/oder sich Keimablagerungen bilden können.From DE-A-3 447 772 a device for disinfecting or cleaning a piping system of a whirlpool tub is known, which is provided with one or more outlet valves for the supply of water and / or air into the interior of the tub. The outlet valves branch off from a circulation system for the cleaning liquid which has a feed pump and is independent of the tub interior and are formed in the closure point which is liquid-tight with respect to the tub interior for the flow of cleaning fluid. Cover or shut-off devices are provided as means for the closed position of the outlet nozzles that is liquid-tight with respect to the tub interior. Thus, in a case in which the bathtub adjacent to each nozzle has an outlet which is connected to the inlet suction side of a pump, through which the circulating water is drawn off by the pump during operation and during bathing, the Cover means are used to shut off each nozzle and the associated outlet from the interior of the bathtub in order to supply the disinfectant solution circulating through the nozzle through the assigned outlet during the disinfection. In another case, in which an air supply arrangement is assigned to each nozzle, the means should have a cover element, such as a snap-in cap or a screw-on cap, which fits snugly over the end of each nozzle, so that the circulating disinfectant solution of the nozzle is guided through the assigned air supply arrangement . With this known device a cleaning of the piping system of a whirlpool tub is possible, but it cannot prevent cavities from remaining in the outlet valves immediately above the outlet valve, in which residual water remains and / or germ deposits can form.

Reinigungseinrichtungen für das Rohrleitungssystem einer Whirlpool-Wanne mit einem oder mehreren Austrittsventilen für die Zufuhr von Wasser und/oder Luft in den Innenraum der Wanne sind beispielsweise auch aus dem DE-U-8 416 982 bekannt. Die dortige Wanne hat eine Wannenablauföffnung im Wannenboden sowie im Wandbereich eingebaute Wirbeldüsen für die Einleitung von Wasser oder eines Wasser-Luft-Gemisches und wenigstens einer im Wandbereich angeordneten Absaugöffnung, wobei die Absaugöffnung mit der Saugseite und die Wirbeldüsen mit der Druckseite einer an der Wanne angeordneten Pumpe jeweils über Rohrleitungen verbunden sind. Die Wannenablauföffnung ist nach außen mit einem Ablaufstutzen mit einer Anschlußöffnung für eine Ablaßleitung versehen, die mit einer Entleerungsöffnung an der Pumpe verbunden ist. Die Pumpe ist mit ihrer Entleerungsöffnung im Niveau höher an der Wanne angeordnet als die Anschlußöffnung der Ablaßleitung am Ablaufstutzen und in der Ablaßleitung ist ein mit einem steuerbaren Stellantrieb versehenes Absperrventil angeordnet. Hierdurch soll bei jedem Wasserwechsel vor der endgültigen Inbetriebnahme eine Vorspülung des internen Rohrleitungssystems erfolgen. Die bekannte Reinigungseinrichtung ist aufgrund der vielen Teile und notwendigen Steuerung verhältnismäßig aufwendig in Herstellung und Montage und setzt insbesondere wegen der Notwendigkeit des Niveaus der Pumpe einen bestimmten Platzbedarf voraus, der nicht überall vorhanden ist. Außerdem wird beim Vorspülvorgang Wasser benutzt, welches aus dem Wanneninnenraum stammt, so daß Schmutz in das Rohrleitungssystem eingetragen werden kann. Die Zugabe von Reinigungsmitteln ist, was in manchen Fällen von Keimherden und sonstiger Kontamination des Rohrleitungssystems erforderlich ist, nicht möglich, es sei denn, es würde in zeitaufwendiger Weise eine besondere Wannenfüllung dafür vorgenommen.Cleaning devices for the piping system of a whirlpool tub with one or more outlet valves for the supply of water and / or air into the interior of the tub are also known, for example, from DE-U-8 416 982. The tub there has a tub drain opening in the tub floor and vortex nozzles installed in the wall area for the introduction of water or a water-air mixture and at least one suction opening arranged in the wall area, the suction opening with the suction side and the vortex nozzles with the pressure side one arranged on the tub Pump are connected via pipes. The tub drain opening is provided on the outside with a drain socket with a connection opening for a drain line, which is connected to a drain opening on the pump. The pump is arranged with its emptying opening at a higher level on the trough than the connection opening of the drain line at the outlet connection and a shut-off valve provided with a controllable actuator is arranged in the drain line. This is intended for everyone Before the final commissioning, the internal piping system is prewashed. The known cleaning device is relatively complex to manufacture and assemble due to the large number of parts and the necessary control and, in particular because of the need for the level of the pump, requires a certain amount of space which is not present everywhere. In addition, water is used in the pre-rinsing process, which comes from the tub interior, so that dirt can be introduced into the piping system. The addition of cleaning agents, which is necessary in some cases of germs and other contamination of the piping system, is not possible, unless a special tub filling was carried out in a time-consuming manner.

Aufgabe der vorliegenden Erfindung ist es, eine Reinigungseinrichtung der eingangs genannten Art derart weiter zu entwickeln, daß sie eine zuverlässige Reinigung des Rohrleitungsystems gestattet und dennoch eine einfache Handhabung bei Montage und Betrieb ermöglicht.The object of the present invention is to further develop a cleaning device of the type mentioned at the outset in such a way that it permits reliable cleaning of the pipeline system and nevertheless enables simple handling during assembly and operation.

Diese Aufgabe wird mit der Erfindung im wesentlichen dadurch gelöst, daß die von dem Kreislaufsystem zu dem jeweiligen Austrittsventil abzweigende Wasserzuführleitung in eine in einem Ventilkörper des Austrittsventils angeordnete Wasserverteilungskammer mündet, von welcher ein Wasseraustrittskanal in Richtung des Wanneninnenraumes abzweigt, daß der Verschlußkörper in dem Wasseraustrittskanal angeordnet ist und einen geringeren Querschnitt hat als die Wasserverteilungskammer, die er wasserdicht, axial verstellbar geführt durchsetzt, daß die wannenseitige Stirnfläche des Verschlußkörpers in Verschlußstellung mit der angrenzenden Stirnfläche des Ventilkörpers eben fluchtet oder diese kuppenförmig überragt und daß von der Wasserverteilungskammer die Rückführungsleitung (Spülleitung) abzweigt, welche in Verschlußstellung des Verschlußkörpers in Strömungsverbindung mit der Wasserzufuhrleitung steht.This object is essentially achieved with the invention in that the water supply line branching off from the circulation system to the respective outlet valve opens into a water distribution chamber arranged in a valve body of the outlet valve, from which a water outlet channel branches off in the direction of the tub interior, in that the closure body is arranged in the water outlet channel and has a smaller cross-section than the water distribution chamber, which it penetrates in a watertight, axially adjustable manner, that the end face of the closure body in the closed position is flush with the adjacent end face of the valve body or protrudes dome-shaped and that the return line (flushing line) from the water distribution chamber branches, which is in the closed position of the closure body in flow connection with the water supply line.

Mit der erfindungsgemäßen Lösung wird erreicht, daß in Verschlußstellung des Verschlußkörpers der eine Teil des Austrittsventils von der Reinigungsflüssigkeit durchströmt werden kann, während unmittelbar oberhalb des Austrittsventils keine Vertiefungen zurückbleiben, in denen sich Restwasser aus dem Wanneninnenraum ansammeln und/oder Keimablagerungen bilden könnten. In Öffnungsstellung gibt der Verschlußkörper den Durchgang zum Wanneninnenraum für den Whirlpool-Betrieb frei. Zusammen mit dem Rohrleitungssystem wird also gleichzeitig eine zuverlässige Reinigung der Austrittsdüsen einer Whirlpool-Wanne erreicht. Ein weiterer Vorteil ergibt sich daraus, daß im Reinigungsbetrieb die Wasserverteilungskammer von der Reinigungsflüssigkeit durchspült werden kann, während der Wasseraustrittskanal von dem Verschlußkörper in Verschlußstellung bis zum Wannenboden vollständig ausgefüllt ist und mit diesem dort im wesentlichen fluchtet, so daß Wasseransammlungen vermieden sind.With the solution according to the invention it is achieved that in the closed position of the closure body, part of the outlet valve can be flowed through by the cleaning liquid, while immediately above the outlet valve there are no depressions in which residual water from the tub interior could accumulate and / or germ deposits could form. In the open position, the closure body clears the passage to the tub interior for whirlpool operation. Together with the piping system, reliable cleaning of the outlet nozzles of a whirlpool bath is achieved at the same time. Another advantage arises from the fact that in cleaning operation the water distribution chamber can be flushed with the cleaning liquid, while the water outlet channel is completely filled by the closure body in the closed position up to the tub floor and is essentially flush with it there, so that water accumulations are avoided.

Vorzugsweise durchsetzt der Verschlußkörper den Ventilkörper und damit auch die Wasserverteilungskammer axial vollständig und ist an seinem wannenabgewandten Ende mit einem pneumatisch, hydraulisch oder magnetisch betätigbaren Kolben verbunden. Auf diese Weise kann der Verschlußkörper einfach in Verschluß- und Öffnungsstellung gebracht werden.The closure body preferably passes axially completely through the valve body and thus also the water distribution chamber and is connected at its end facing away from the tub to a pneumatically, hydraulically or magnetically actuated piston. In this way, the closure body can be easily brought into the closed and open positions.

In weiterer Ausgestaltung des Erfindungsgedankens ist in dem Ventilkörper und/oder dem Ventilgehäuse eine Luftverteilungskammer angeordnet, in welche eine Luftzufuhrleitung mündet und von welcher ein Luftaustrittskanal abzweigt; in dem Luftaustrittskanal ist dabei ein die Luftverteilungskammer durchsetzender, vorzugsweise hohlzylindrischer, Absperrkörper luftund wasserdicht verstellbar geführt, dessen wannenseitige Stirnfläche in Verschlußstellung mit der angrenzenden Stirnfläche des Ventilkörpers oder des Ventilgehäuses eben fluchtet oder diese kuppenförmig überragt. Hierdurch wird erreicht, daß sich auch im Bereich der Luftzufuhr keine nachteiligen Wasserreste ansammeln können.In a further embodiment of the inventive concept, an air distribution chamber is arranged in the valve body and / or the valve housing, into which an air supply line opens and from which an air outlet duct branches; in the air outlet duct there is a through the air distribution chamber, preferably hollow cylindrical, shut-off body adjustable and airtight adjustable, the tub-side end face in the closed position is flush with the adjacent end face of the valve body or the valve housing or protrudes dome-shaped. This ensures that no disadvantageous water residues can accumulate in the area of the air supply.

Vorzugsweise durchsetzt auch der Absperrkörper den Ventilkörper axial vollständig und an seinem wannenabgewandten Ende ist er mit einem pneumatisch, hydraulisch oder magnetisch betätigbaren Kolben verbunden, welcher derselbe Kolben sein kann, von welchem auch der Verschlußkörper getragen wird.The shut-off body preferably also passes axially completely through the valve body and at its end facing away from the tub it is connected to a pneumatically, hydraulically or magnetically actuable piston which can be the same piston by which the closure body is also carried.

Der genannte Kolben wird vorzugsweise in dem Ventilgehäuse axial geführt.The piston mentioned is preferably guided axially in the valve housing.

Bei einer besonderen Ausgestaltung des Erfindungsgedankens weist das Kreislaufsystem zwei im wesentlichen parallele Rohrleitungszweige auf, deren einer Zweig die Vorlaufleitung ist, von der die Austrittsventile abzweigen, von welchen jeweils Rückführungsleitungen (Spülleitungen) in den anderen Rohrleitungszweig, der die Rücklaufleitung bildet, münden. Auf diese Weise ist bei raumsparender Unterbringung des Kreislaufsystems eine vollständige Durchströmung und Reinigung der Austrittsventile neben dem Rohrleitungssystem selbst gewährleistet.In a special embodiment of the concept of the invention, the circulation system has two substantially parallel pipeline branches, one branch of which is the supply line, from which the outlet valves branch, from each of which return lines (flushing lines) open into the other line of pipeline, which forms the return line. In this way, a complete flow and cleaning of the outlet valves next to the piping system itself is guaranteed with space-saving accommodation of the circulation system.

In das Kreislaufsystem, vorzugsweise in die Rücklaufleitung, kann eine Frischwasserleitung münden, die der zur Verfügungstellung des erforderlichen Wassers für die Reinigung, das Nachspülen und die Versorgung der Austrittsventile im Whirlpool-Betrieb dient.A fresh water line can open into the circulation system, preferably into the return line, which serves to provide the water required for cleaning, rinsing and supplying the outlet valves in whirlpool operation.

Dabei mündet die Frischwasserleitung vorzugsweise in einen als Vorratsbehälter dienenden Wasserkasten, von welchem eine Verbindungsleitung zu dem Kreislaufsystem abzweigt.The fresh water line preferably opens into a water tank serving as a storage container, from which a connecting line branches off to the circulatory system.

In das Kreislaufsystem, vorzugsweise in die Rücklaufleitung, kann ferner eine Reinigungsmittelzufuhrleitung münden, wodurch eine vereinfachte Reinigungsmittelzufuhr zum Frischwasser möglich ist.A cleaning agent supply line can also open into the circulatory system, preferably into the return line, whereby a simplified supply of cleaning agent to the fresh water is possible.

Das Kreislaufsystem steht bei einer bevorzugten Ausgestaltung der Erfindung, vorzugsweise an der von der Förderpumpe am entferntesten liegenden Stelle, mit dem Wasserabfluß der Wanne in Strömungsverbindung. Damit kann die verbrauchte Reinigungsflüssigkeit über den gegenüber dem Kreislaufsystem öffenbaren, aber auch wieder schließbaren Wannenabfluß abgelassen werden.In a preferred embodiment of the invention, the circulatory system is in flow connection with the water outflow from the tub, preferably at the point furthest away from the feed pump. The used cleaning liquid can thus be drained off via the tub drain which can be opened but can also be closed again with respect to the circulatory system.

Zur sicheren Montage sind Vorlaufleitung und Rücklaufleitung vorzugsweise in Abständen über Abstandshalteelemente miteinander verbunden, was bei der Länge der Leitungen zweckmäßig sein kann.For safe installation, the supply line and return line are preferably connected to one another at intervals by means of spacer elements, which can be expedient given the length of the lines.

In konstruktiv einfacher Ausgestaltung des Erfindungsgedankens können dabei die Anschlußstutzen für die Austrittsventile, die Rückführungsleitungen, die Frischwasserleitung, die Verbindungsleitung und/oder die Reinigungsmittelzufuhrleitung einstückig an den Abstandshalteelementen ausgebildet sein.In a structurally simple embodiment of the inventive concept, the connecting pieces for the outlet valves, the return lines, the fresh water line, the connecting line and / or the detergent supply line can be integrally formed on the spacer elements.

Die Montage wird dann noch weiter vereinfacht, wenn die Abstandshalteelemente muffenförmige Abschnitte aufweisen, durch welche die Vorlaufleitung und/oder die Rücklaufleitung hindurchgeführt sind.The assembly is further simplified if the spacer elements have sleeve-shaped sections through which the feed line and / or the return line are passed.

Die Reinigungseinrichtung gemäß Fig. 1 für das Rohrleitungssystem einer Whirlpool-Wanne mit mehreren im Bodenbereich der Wanne 1 angeordneten Austrittsventilen 2 für die Zufuhr von Wasser und/oder Luft in den Innenraum 5 der Wanne 1 zeichnet sich dadurch aus, daß die Austrittsventile 2 von einem eine Förderpumpe 3 aufweisenden, von dem Wanneninnenraum 5 unabhängigen Kreislaufsystem 4 für die Reinigungsflüssigkeit abzweigen und in Verschlußstellung von der Reinigungsflüssigkeit durchströmt werden, aber den Austritt von Reinigungsflüssigkeit in den Wanneninnenraum 5 verhindern. Das Kreislaufsystem 4 weist zu diesem Zweck zwei im wesentlichen parallele, im dargestellten Fall in Wannenlängsrichtung unterhalb der Wanne 1 raumsparend verlaufende Rohrleitungszweige 6 und 7 auf. Von dem einen Rohrleitungszweig (Vorlaufzweig) 6 zweigen die Austrittsventile 2 ab. Von den Austrittsventilen 2 münden jeweils Rückführungsleitungen (Spülleitungen) 8 in den anderen Rohrleitungszweig (Rücklaufzweig) 7. Dadurch wird gewährleistet, daß im Reinigungsbetrieb nicht nur das gesamte Rohrleitungssystem, sondern auch die Hohlräume der Austrittsventile 2 von Reinigungsflüssigkeit durchströmt werden. Eine Frischwasserleitung 9 mündet in einen Wasserkasten 10, von welchem eine Verbindungsleitung 11 zu dem Kreislaufsystem 4 abzweigt. Ferner mündet in den Rücklaufzweig 7 eine Reinigungsmittelzufuhrleitung 13, welche an ihrem oberen Ende für den Benutzer zugänglich einen Reinigungsmittelaufnahmebehälter 31 trägt. Die Reinigungsmittelzufuhr kann so ausgebildet sein, daß die Detergenzien u. dgl. beim Umlaufen der Reinigungsflüssigkeit in dem Kreislaufsystem 4 aufgrund des Venturi-Prinzips in das Kreislaufsystem 4 allmählich eingezogen werden. Das Kreislaufsystem 4 steht an dem der Förderpumpe 3 entgegengesetzten Ende der beiden parallelen Rohrleitungszweige 6, 7 mit dem Wannenausguß 12 in Strömungsverbindung, wodurch eine Entleerung des Kreislaufsystems 4 einfach erfolgen kann. Der Wannenabfluß 12 kann insbesondere in eine Verschlußstellung und eine Öffnungsstellung bezüglich des Kreislaufsystems 4 gebracht werden.The cleaning device according to FIG. 1 for the piping system of a whirlpool tub with a plurality of outlet valves 2 arranged in the bottom region of the tub 1 for the supply of water and / or air into the interior 5 of the tub 1 is characterized in that the outlet valves 2 have one branch off a circulation system 4 for the cleaning liquid which has a feed pump 3 and is independent of the tub interior 5 and through which the cleaning liquid flows in the closed position, but prevent the escape of cleaning fluid into the tub interior 5. For this purpose, the circulatory system 4 has two essentially parallel pipeline branches 6 and 7 which run in the longitudinal direction of the tub below the tub 1 and save space. The outlet valves 2 branch off from one pipeline branch (flow branch) 6. From the outlet valves 2, return lines (rinsing lines) 8 each open into the other pipeline branch (Return branch) 7. This ensures that in cleaning operation not only the entire pipe system, but also the cavities of the outlet valves 2 are flowed through by cleaning liquid. A fresh water line 9 opens into a water tank 10, from which a connecting line 11 branches off to the circulatory system 4. Furthermore, a detergent supply line 13 opens into the return branch 7 and carries a detergent receptacle 31 accessible to the user at its upper end. The detergent supply can be designed so that the detergents u. Like. Are gradually drawn into the circulatory system 4 when circulating the cleaning liquid in the circulatory system 4 due to the Venturi principle. The circulatory system 4 is in flow connection at the end of the two parallel pipeline branches 6, 7 opposite the feed pump 3 with the tub spout 12, so that the circulatory system 4 can be emptied easily. The tub drain 12 can in particular be brought into a closed position and an open position with respect to the circulatory system 4.

Vorlaufzweig 6 und Rücklaufzweig 7 sind in etwa gleichen Abständen über Abstandshalteelemente 14 miteinander verbunden, so daß eine stabile Einheit entsteht. Die Anschlußstutzen 15 für die Austrittsventile 2 und/oder die Rückführungsleitung 8 und/oder die Verbindungsleitung 11 und/oder die Reinigungsmittelzufuhrleitung 13 sind einstückig an dem Abstandshalteelement 14 ausgebildet, was eine einfache Montage gestattet. Die Abstandshalteelemente haben ferner muffenförmige Abschnitte 16, durch welche die Vorlaufleitung 6 bzw. die Rücklaufleitung 7 hindurchgeführt sind. Hierdurch wird die Montage noch weiter vereinfacht.Forward branch 6 and return branch 7 are connected to one another at approximately equal intervals by spacer elements 14, so that a stable unit is created. The connecting piece 15 for the outlet valves 2 and / or the return line 8 and / or the connecting line 11 and / or the detergent supply line 13 are integrally formed on the spacer element 14, which allows easy assembly. The spacer elements also have sleeve-shaped sections 16, through which the feed line 6 and the return line 7 are passed. This further simplifies assembly.

In Fig. 2 ist ein Austrittsventil 2 für Whirlpool-Wannen schematisch veranschaulicht, welches sich insbesondere für eine Reinigungseinrichtung der zuvor geschilderten Art eignet. Die Wasserzufuhrleitung 17 zu dem Austrittsventil 2 mündet dabei in eine in dem Ventilkörper 18 angeordnete Wasserverteilungskammer 19, von welcher der Wasseraustrittskanal 20 im dargestellten Falle senkrecht in Richtung des Wanneninnenraumes 5 abzweigt. In dem Wasseraustrittskanal 20 ist ein die Wasserverteilungskammer 19 durchsetzender, zylindrischer Verschlußkörper wasserdicht axial verstellbar geführt. Der Verschlußkörper 21 hat einen geringeren Querschnitt als die Wasserverteilungskammer 19, so daß auch in Verschlußstellung ein Ringkammerteil der Wasserverteilungskammer 19, in welchen die Wasserzufuhrleitung 17 mündet, freibleibt. Die wannenseitige Stirnfläche 22 des Verschlußkörpers 21 fluchtet in Verschlußstellung mit der angrenzenden Stirnfläche 23 des Ventilkörpers 18 eben oder überragt diese entsprechend der Darstellung nur leicht kuppenförmig. Wird also das Ventilgehäuse 25 mit dem Ventilkörper 18, ohne daß eine Vertiefung zurückbleibt, in den Wannenboden 32 entsprechend der zeichnerischen Darstellung eingesetzt, so verbleiben keine Vertiefungen, in welchen sich in nachteiliger Weise Restwasser im Ventilbereich ansammeln könnte. Von der Wasserverteilungskammer 19 zweigt eine Rückführungsleitung (Spülleitung) 8 ab, welche wegen des freibleibenden Ringkammerteils der Wasserverteilungskammer 19 auch in Verschlußstellung des Verschlußkörpers 21 in Strömungsverbindung mit der Wasserzufuhrleitung 17 steht. Auf diese Weise kann erreicht werden, daß insbesondere bei einer Reinigungseinrichtung der oben geschilderten Art auch die inneren Hohlräume des Austrittsventils 2 von Reinigungsflüssigkeit durchströmt werden können.In Fig. 2, an outlet valve 2 for whirlpool tubs is illustrated schematically, which is particularly suitable for a cleaning device of the type described above is suitable. The water supply line 17 to the outlet valve 2 opens into a water distribution chamber 19 arranged in the valve body 18, from which the water outlet channel 20 branches vertically in the direction shown in the tub interior 5 in the case shown. In the water outlet channel 20, a cylindrical closure body penetrating the water distribution chamber 19 is axially adjustable in a watertight manner. The closure body 21 has a smaller cross section than the water distribution chamber 19, so that even in the closed position, an annular chamber part of the water distribution chamber 19, in which the water supply line 17 opens, remains free. The end face 22 of the closure body 21 on the side of the tub is flush with the adjoining end face 23 of the valve body 18 in the closed position or projects only slightly dome-shaped as shown. Thus, if the valve housing 25 with the valve body 18 is inserted into the trough bottom 32 without leaving a depression, as shown in the drawing, there are no depressions in which residual water could disadvantageously accumulate in the valve area. A return line (rinsing line) 8 branches off from the water distribution chamber 19 and, because of the remaining free ring chamber part of the water distribution chamber 19, is also in flow connection with the water supply line 17 when the closure body 21 is in the closed position. In this way it can be achieved that cleaning fluid can also flow through the inner cavities of the outlet valve 2, in particular in the case of a cleaning device of the type described above.

Der Verschlußkörper 21 durchsetzt den Ventilkörper 18 axial vollständig und ist an seinem wannenabgewandten Ende mit einem pneumatisch, hydraulisch oder magnetisch betätigbaren Kolben 24 verbunden. Durch die genannte axiale Betätigung des Kolbens 24 kann also der Verschlußkörper 21 leicht aus der dargestellten Verschlußstellung in eine Öffnungsstellung so weit nach unten verfahren werden, daß das über die Wasserzufuhrleitung 17 zugeführte Wasser aus dem Wasseraustrittskanal 20 in das Wanneninnere 5 austritt, wobei im dargestellten Falle auf den Ventilkörper 18 noch ein Düsenkörper 33 aufgesetzt ist, in welchem eine selbständige Erfindung verwirklicht ist, die in der DE-A-3 640 497 näher beschrieben wird.The closure body 21 passes completely axially through the valve body 18 and is connected at its end remote from the tub to a pneumatically, hydraulically or magnetically actuable piston 24. By said axial actuation of the piston 24, the closure body 21 can thus be moved so far down from the illustrated closure position into an open position that the water supplied via the water supply line 17 emerges from the water outlet channel 20 into the tub interior 5, in the case shown a valve body 18 on the valve body 33 is set up, in which an independent invention is implemented, which is described in more detail in DE-A-3 640 497.

In dem Ventilkörper 18 und dem Ventilgehäuse 25 ist eine die Wasserverteilungskammer 19 ringförmig umgebende Luftverteilungskammer 26 angeordnet, in welche die Luftzufuhrleitung 27 mündet und von welcher ein den Wasseraustrittskanal 20 ringförmige umgebender Luftaustrittskanal 28 abzweigt. In dem Luftaustrittskanal 28 ist ein die Luftverteilungskammer 26 durchsetzender, hohlzylindrischer Absperrkörper 29 luft- und wasserdicht axial verstellbar geführt. Die wannenseitige Stirnfläche 30 des Absperrkörpers 29 fluchtet ebenfalls in Verschlußstellung mit der angrenzenden Stirnfläche 23 des Ventilkörpers 18 oder des Ventilgehäuses 25 eben oder überragt diese nur leicht kuppenförmig entsprechend der Darstellung, so daß sich auch hier in Verschlußstellung kein Wasser ansammeln kann. Der Absperrkörper 29 durchsetzt den Ventilkörper 18 ebenfalls axial vollständig und ist an seinem wannenseitigen Ende mit dem Kolben 24 verbunden, der seinerseits in dem Ventilgehäuse 25 axial geführt sein kann. Wasser- und Luftzufuhr werden so gesteuert, daß der Verschlußkörper 21 nur dann in Öffnungsstellung gebracht werden kann, wenn auch Luftdruck ansteht. Umgekehrt kann der Luftdruck nur dann abgestellt werden, wenn der Verschlußkörper 21 sich in Verschlußstellung befindet. Bei dem Austrittsventil 2 wird für relativ große Schließkräfte gesorgt, damit ein hermetischer Abschluß des Wanneninnenraumes 5 gegenüber dem Kreislaufsystem 4 in Verschlußstellung von Verschlußkörper 21 und Absperrkörper 29 immer sichergestellt ist.Arranged in the valve body 18 and the valve housing 25 is an air distribution chamber 26 which surrounds the water distribution chamber 19 in an annular manner, into which the air supply line 27 opens and from which an air outlet channel 28 which surrounds the water outlet channel 20 branches off. In the air outlet duct 28, a hollow cylindrical shut-off body 29 passing through the air distribution chamber 26 is axially adjustable in an air-tight and watertight manner. The tub-side end face 30 of the shut-off body 29 is also flush in the closed position with the adjacent end face 23 of the valve body 18 or the valve housing 25 or projects only slightly dome-shaped in accordance with the illustration, so that no water can accumulate here in the closed position. The shut-off body 29 also passes completely axially through the valve body 18 and is connected at its tub end to the piston 24, which in turn can be guided axially in the valve housing 25. Water and air supply are controlled so that the closure body 21 can only be brought into the open position when air pressure is also present. Conversely, the air pressure can only be switched off when the closure body 21 is in the closed position. Relatively large closing forces are provided in the outlet valve 2, so that a hermetic closure of the tub interior 5 with respect to the circulatory system 4 is always ensured in the closed position of the closure body 21 and shut-off body 29.

Die sich aus den Fig. 3a und 3b ergebende Ausgestaltung des Austrittsventils 2 funktioniert im Prinzip genauso, wie das Austrittsventil 2 nach Fig. 2. Lediglich die Zuordnung der einzelnen Teile, Leitungen und Kammern ist etwas verändert. Dichtungsringe sorgen für eine zuverlässige Abdichtung des Verschlußkörpers 21 und des Absperrkörpers 29 gegenüber dem Ventilkörper 18 bzw. dem Ventilgehäuse 25 in Verschlußstellung. In der linken Hälfte der zeichnerischen Darstellung der Fig. 3a und 3b ist jeweils die Öffnungsstellung für Wasserund Luftaustritt in den Wanneninnenraum 5, auf der jeweils rechten Seite die Verschlußstellung veranschaulicht, wobei jedoch ein Durchspülen des Ventilinnenraumes über die Spülleitung 8 ermöglicht ist.The configuration of the outlet valve 2 resulting from FIGS. 3a and 3b works in principle in exactly the same way as the outlet valve 2 according to FIG. 2. Only the assignment of the individual parts, lines and chambers is somewhat changed. Sealing rings ensure reliable sealing of the closure body 21 and the shut-off body 29 with respect to the valve body 18 and the valve housing 25 in the closed position. 3a and 3b each show the opening position for water and air outlet into the tub interior 5, on the right side in each case the closed position is illustrated, but flushing the valve interior via the flushing line 8 is made possible.
