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, vorzugsweise im Bodenbereich der Wanne angeordneten, Austrittsventilen für die Zufuhr von Wasser und/oder Luft in den Innenraum sowie ein Austrittsventil für die Wasser- und/oder Luftzufuhr einer Whirlpool-Wanne, insbesondere einer Reinigungseinrichtung der zuvor genannten Art.The invention relates to a cleaning device for the piping system of a whirlpool tub with one or more outlet valves, preferably arranged in the bottom region of the tub, for the supply of water and / or air into the interior and an outlet valve for the water and / or air supply a whirlpool tub, in particular a cleaning device of the aforementioned type.

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 aus dem DE-GM 84 16 982 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 Platzgedard 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 Keimerden 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 known for example from DE-GM 84 16 982. 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. In this way, the internal piping system should be pre-rinsed each time the water is changed before it is finally put into operation. The known cleaning device is relatively complex to manufacture due to the many parts and necessary control and assembly and, particularly because of the need for the level of the pump, requires a certain amount of space that is not available 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 pipe 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 zu schaffen, welches ein­fach in Herstellung, Montage und Betrieb ist sowie eine zu­verlässige Reinigung des Rohrleitungssystems gestattet.The object of the present invention is to provide a cleaning device of the type mentioned at the outset which is simple to manufacture, assemble and operate and which permits reliable cleaning of the piping system.

Diese Aufgabe wird mit der Erfindung im wesentlichen dadurch gelöst, daß die Austrittsventile von einem eine Förderpumpe aufweisenden, von dem Wanneninnenraum unabhängigen Kreislauf­system für die Reinigungsflüssigkeit abzweigen und in Ver­schlußstellung von der Reinigungsflüssigkeit durchströmt werden, aber den Austritt von Reinigungsflüssigkeit in den Wanneninnenraum verhindern.This object is essentially achieved with the invention in that 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 through which the cleaning liquid flows in the closed position, but prevent the escape of cleaning fluid into the tub interior.

Die neue Reinigungseinrichtung besteht damit aus wenigen Teilen. Ein Abschnitt des Kreislaufsystems wird von denjenigen Rohrleitungen gebildet, die ohnehin für die Wasserzufuhr durch die Austrittsventile (in deren Öffnungsstellung) in den Wannen­innenraum erforderlich sind, so daß nur noch das Kreislauf­system zur Förderpumpe hin zurückgeführt werden muß. Die Rei­nigungsflüssigkeit, welche in dem Kreislaufsystem umläuft, gelangt in sämtliche Hohlräume der Anschlußventile und der Rohrleitungen, so daß eine vollständige und zuverlässige Rei­nigung erfolgt. Von der nächsten Inbetriebnahme der Whirlpool-­Anlage wird die Reinigungsflüssigkeit aus dem Kreislaufsystem entfernt.The new cleaning device thus consists of a few parts. A section of the circulatory system is formed by those pipelines which are required anyway for the water supply through the outlet valves (in their open position) into the tub interior, so that only the circulatory system has to be returned to the feed pump. The cleaning liquid, which circulates in the circulatory system, gets into all cavities of the connection valves and the Pipelines so that complete and reliable cleaning takes place. The cleaning liquid is removed from the circulatory system the next time the whirlpool system is started up.

Bei einer besonderen Ausgestaltung des Erfindungsgedankens weist das Kreislaufsystem zwei im wesentlichen parallele, vorzugsweise in Wannenlängsrichtung unterhalb der Wanne ver­laufende Rohrleitungszweige auf, von deren einen Rohrleitungs­zweig (Vorlaufzweig) die Austrittsventile abzweigen, von wel­chen jeweils Rückführungsleitungen (Spülleitungen) in den an­deren Rohrleitungszweig (Rücklaufzweig) 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 essentially parallel pipeline branches, preferably running in the longitudinal direction of the tub below the tub, from whose one pipeline branch (flow branch) branch the outlet valves, from each of which return lines (flushing lines) open into the other pipeline branch (return branch) . 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 den Rücklaufzweig, 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 pipe, which serves to provide the water required for cleaning, rinsing and supplying the outlet valves in whirlpool operation, can open into the circulation system, preferably into the return branch.

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 den Rücklaufzweig, kann ferner eine Reinigungsmittelzfuhrleitung 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 branch, 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 und/oder die Rückführungsleitungen und/oder die Frischwasser­leitung bzw. 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 and / or the return lines and / or the fresh water line or 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 bzw. die Rücklaufleitung hindurch­geführt sind.The assembly is further simplified if the spacer elements have sleeve-shaped sections through which the feed line or the return line are passed.

Das erfindungsgemäße Austrittsventil für die Wasser- und/oder Luftzufuhr einer Whirlpool-Wanne, insbesondere für eine Rei­nigungseinrichtung der zuvor näher erörterten Art zeichnet sich dadurch aus, daß die Wasserzufuhrleitung in eine in dem Ventilkörper angeordnete Wasserverteilungskammer mündet, von welcher der Wasseraustrittskanal in Richtung des Wanneninnen­raumes abzweigt und daß in dem Wannenaustrittskanal ein die Wasserverteilungskammer durchsetzender, vorzugsweise zylin­ drischer Verschlußkörper wasserdicht axial verstellbar geführt ist, welcher einen geringeren Querschnitt hat als die Wasser­verteilungskammer und dessen wannenseitige Stirnfläche in Ver­schlußstellung mit der angrenzenden Stirnfläche des Ventil­körpers eben fluchtet oder diese nur leicht kuppenförmig über­rage. Hierbei handelt es sich also um ein Austrittsventil, welches in Verschlußstellung des Verschlußkörpers den völligen Abschluß einer Reinigungseinrichtung der zuvor erörterten Art von dem Wanneninnenraum gestattet und andererseits verhindert, daß in dem Austrittsventil oder unmittelbar oberhalb des Austrittsventiles Hohlräume verbleiben, in welchen Restwasser stehenbleiben und/oder sich Keimablagerungen bilden könnten. In Öffnungsstellung gibt der Verschlußkörper den Durchgang zum Wanneninnenraum für den Whirlpool-Betrieb frei. Der erfindungs­gemäße Vorteil wird also insbesondere dadurch erreicht, daß der eine Teil des Austrittsventils von der Reinigungsflüssig­keit der Reinigungseinrichtung durchströmt werden kann, wäh­rend unmittelbar oberhalb des Austrittsventils keine Vertie­fungen zurückbleiben, in denen sich Restwasser aus dem Wannen­innenraum ansammeln könnte.The outlet valve according to the invention for the water and / or air supply of a whirlpool tub, in particular for a cleaning device of the type discussed in more detail above, is characterized in that the water supply line opens into a water distribution chamber arranged in the valve body, from which the water outlet channel leads in the direction of the tub interior branches off and that in the tub outlet channel penetrating the water distribution chamber, preferably cylin drischer closure body is guided axially adjustable waterproof, which has a smaller cross-section than the water distribution chamber and its tub-side end face in the closed position flush with the adjacent end face of the valve body or only slightly protrudes dome-shaped. This is an outlet valve which, when the closure body is in the closed position, allows a cleaning device of the type previously discussed to be completely closed off from the tub interior and, on the other hand, prevents cavities from remaining in the outlet valve or directly above the outlet valve, in which residual water remains and / or germ deposits could form. In the open position, the closure body clears the passage to the tub interior for whirlpool operation. The advantage according to the invention is thus achieved in particular in that a part of the outlet valve can be flowed through by the cleaning liquid of the cleaning device, while there are no depressions immediately above the outlet valve, in which residual water from the tub interior could collect.

Da bei einer bevorzugten Ausgestaltung der Erfindung von der Wasserverteilungskammer eine Rückführungsleitung (Spülleitung) abzweigt, welche in Verschlußstellung des Verschlußkörpers in Strömungsverbindung mit der Wasserzufuhrleitung steht, kann im Reinigungsbetrieb die Wasserverteilungskammer von der Reinigungsflüssigkeit durchspült werden, 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.Since, in a preferred embodiment of the invention, a return line (flushing line) branches off from the water distribution chamber and is in flow connection with the water supply line in the closed position of the closure body, the cleaning liquid can be flushed through the water distribution chamber in cleaning operation, while the water outlet channel from the closure body in the closed position to The tub floor is completely filled and is essentially flush with it, 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, vorzugsweise die Wasserverteilungskammer ringförmig umgebende, Luftverteilungs­kammer angeordnet, in welche die Luftzufuhrleitung mündet und von welcher der ggf. ringförmige Luftaustrittskanal abzweigt; in dem Luftaustrittskanal ist dabei ein die Luftverteilungs­kammer durchsetzender, vorzugsweise hohlzylindrischer, Absperr­körper luft- und wasserdicht verstellbar geführt, dessen wannenseitige Stirnfläche in Verschlußstellung mit der an­grenzenden Stirnfläche des Ventilkörpers oder des Ventilge­häuses eben fluchtet oder diese nur leicht 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, preferably surrounding the water distribution chamber in an annular manner, is arranged in the valve body and / or the valve housing, into which the air supply line opens and from which the possibly annular air outlet duct branches; In the air outlet duct, a preferably hollow-cylindrical shut-off body penetrating the air distribution chamber is adjustable in an airtight and watertight manner, the end face of which at the closed position is flush with the adjoining end face of the valve body or the valve housing or only slightly protrudes over the top. This ensures that no disadvantageous water residues can accumulate in the area of the air supply.

Vorzugsweise durchsetzt auch der Ansperrkörper 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 Vershlußkörper getragen wird.The locking 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.

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. The circulatory system 4 has for this purpose two substantially parallel, in case shown in the longitudinal direction of the tub below the tub 1 extending pipe branches 6 and 7 in a space-saving manner. The outlet valves 2 branch off from one pipeline branch (flow branch) 6. From the outlet valves 2 each return lines (rinsing lines) 8 open into the other pipe 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.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 cleaning agent supply line 13 are integrally formed on the spacer element 14, which allows easy assembly.

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.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 sind 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 Wasservertelungskammer 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.2 schematically illustrates an outlet valve 2 for whirlpool baths, which are particularly suitable for a cleaning device of the type described above. 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, in particular with a Cleaning device of the type described above, the internal cavities of the outlet valve 2 can be flowed through by cleaning liquid.

Der Verschlußkörper 21 durchsetzt den Ventilkörper 18 axial vollständig und ist an seinem wannenabgewandten Ende mit einem pneumatisch, hydraulisch oder magnetisch betätigbaren Kolben 2 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 einer Parallelanmeldung 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 actuated piston 2. By said axial actuation of the piston 24, the closure body 21 can thus be easily moved from the illustrated closure position into an open position so far down 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 nozzle body 33 is also placed on the valve body 18, in which an independent invention is implemented, which is described in more detail in a parallel application.

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 dan 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 surrounding 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 only projects slightly beyond it in a dome-shaped manner as shown, so that no water can accumulate here in the closed position. The shut-off body 29 passes through the valve body 18 also axially complete 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 Wasser- und Luftaustritt in den Wanneninnenraum 5, auf der jeweils rechten Seit 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. In the left half of the graphical representation of FIGS. 3a and 3b, the opening position for water and air outlet into the tub interior 5 is illustrated, on the right side in each case the closed position is illustrated, but flushing of the valve interior via the flushing line 8 is made possible.
