Description

Die Erfindung bezieht sich auf eine Whirlpoolwanne mit einer Abflußeinrichtung und einem für die Beaufschlagung wenigstens einer in das Wanneninnere mündenden Düse mit Wasser und/oder Luft bestimmten, mit einer Umwälzpumpe ausgestatteten Rohrleitungssystem, welches mit einer im Wannenboden oder einer Wannenseitenwand vorgesehenen Abflußöffnung über ein Anschlußventil und eine Anschlußkammer in Strömungsverbindung steht, wobei in die Anschlußkammer ein mit einem Abflußventil ausgestatteter und in die Abflußleitung mündender Abflußstutzen hineinragt und wobei das Anschlußventil zwischen dem Abflußstutzen und der Anschlußkammerwandung wirksam ist.The invention relates to a whirlpool tub with a drainage device and a pipe system equipped with a circulating pump for supplying at least one nozzle opening into the tub interior with water and / or air a connection chamber is in flow connection, a discharge nozzle equipped with a discharge valve and opening into the discharge line protruding into the connection chamber and the connection valve being effective between the discharge nozzle and the connection chamber wall.

Bei einer derartigen Whirlpoolwanne besteht das zwischen Abflußstutzen und Anschlußkammerwandung wirksame Anschlußventil z.B. aus einer auf dem Abflußstutzen festgelegten elastischen Membranen, bspw. aus Gummi, welche in Schließstellung mit ihrem Außenrand an der Anschlußkammerwandung bzw. eines Teils derselben zum Zwecke der Abdichtung anliegt und sich bei Überdruck oder Unterdruck im Rohrleitungssystem bzw. in der Anschlußkammer gegenüber dem Wanneninneren entweder zum Wanneninneren hin oder vom Wanneninneneren weg biegt und dadurch den Strömungsquerschnitt des Anschlußventils mehr oder weniger freigibt. Die Dichtwirkung eines derartigen Anschlußventils, welches einen ungünstigen Strömungswiderstand hat, ist verhältnismäßig gering. Bei hohen Strömungsgeschwindigkeiten enstehen undefinierte Strömungsverhältnisse. Bei Unterdruck in dem Kammerbereich oberhalb des Abflußventils, also bspw. bei Öffnung des Abflußventils, wird unerwünscht, Wasser bzw. Reinigungsflüssigkeit aus dem Rohrleitungssystem abgesaugt. Das Rohrleitungssystem soll aber insbesondere nach dem Ablassen des Badewassers nach dem Baden mit dem mit Reinigungs- und Desinfektionsmittel versehenen Badewasser möglichst vollständig gefüllt bleiben.In such a whirlpool tub, the connection valve effective between the drain connection and the connection chamber wall consists, for example, of an elastic membrane fixed on the discharge connection, for example made of rubber, which in the closed position rests with its outer edge on the connection chamber wall or a part thereof for the purpose of sealing and is exposed to excess pressure or negative pressure in the piping system or in the connection chamber opposite the inside of the tub either to the inside of the tub bends towards or away from the interior of the tub and thereby more or less releases the flow cross-section of the connection valve. The sealing effect of such a connection valve, which has an unfavorable flow resistance, is relatively low. At high flow velocities, undefined flow conditions arise. In the event of negative pressure in the chamber area above the drain valve, that is to say, for example, when the drain valve is opened, water or cleaning fluid is undesirably sucked out of the pipeline system. However, especially after the bath water has been drained, the piping system should remain as completely filled as possible with the bath water provided with detergent and disinfectant.

Aufgabe der vorliegenden Erfindung ist es, eine Whirlpoolwanne der gattungsgemäßen Art unter Vermeidung der zuvor genannten Nachteile mit besserer Funktionsweise auszustatten.The object of the present invention is to provide a whirlpool bath of the generic type with better functionality while avoiding the aforementioned disadvantages.

Diese Aufgabe wird bei einer Whirlpoolwanne der eingangs genannten Art erfindungsgemäß im wesentlichen dadurch gelöst, daß das Anschlußventil einen an dem Abflußstutzen geführten Ventilkörper aufweist, welcher unter der Wirkung einer Schließfeder in Richtung seines Dichtsitzes gedrückt wird, und daß der Dichtsitz von sich in Schließrichtung konisch verengenden Ventilsitzflächen des Abflußstutzens und der Anschlußkammerwandung gebildet ist. Bei einer solchen Whirlpoolwanne nimmt der Ventilkörper des Anschlußventils entsprechend den jeweiligen Druckverhältnissen stets wiederholbar eine definierte Schließ- oder Öffnungsstellung ein. Bei Betätigung der Umwälzpumpe in dem Rohrleitungssystem, also bei Betrieb der Whirlpooldüse sorgt der in der Anschlußkammer auftretende Unterdruck für ein Abheben des Ventilkörpers des Anschlußventils von den konischen Ventilsitzflächen zwischen Abflußstutzen und Anschlußkammerwandung. Aufgrund des Strömungsdruckes wird der Ventilkörper des Anschlußventils gegen die Wirkung der Schließ feder offengehalten. Bei Abschalten der Umwälzpumpe wird das Anschlußventil unter der Wirkung der Schließfeder sofort wieder zuverlässig geschlossen. Ein Unterdruck oberhalb des Anschlußventils erhöht die Schließkraft aufgrund der konisch aufeinander zulaufenden Ventilsitzflächen des Anschlußventils. Durch das Hineinragen des Abflußstutzens in die Anschlußkammer bis nahe zur Abflußöffnung im Wannenboden bleibt der gesamte Bereich der Anschlußkammer während der Dauer zwischen zwei Benutzungen der Whirlpoolwanne mit Reinigungsflüssigkeit gefüllt, so daß sich im gesamten Bereich unterhalb des Anschlußventils kein nachhaltiger Schmutz ablagern kann.This object is achieved in a whirlpool tub of the type mentioned essentially according to the invention in that the connection valve has a valve body which is guided on the drain connection and is pressed under the action of a closing spring in the direction of its sealing seat, and that the sealing seat narrows conically in the closing direction Valve seat surfaces of the drain connector and the connection chamber wall is formed. In such a whirlpool tub, the valve body of the connection valve always assumes a defined closing or opening position in accordance with the respective pressure conditions. When the circulation pump in the pipeline system is actuated, that is to say when the whirl pool nozzle is in operation, the negative pressure which occurs in the connection chamber ensures that the valve body of the connection valve is lifted from the conical valve seat surfaces between the discharge nozzle and Connection chamber wall. Due to the flow pressure, the valve body of the connecting valve is kept open against the action of the closing spring. When the circulation pump is switched off, the connection valve is immediately reliably closed again under the action of the closing spring. A negative pressure above the connection valve increases the closing force due to the conically tapering valve seat surfaces of the connection valve. By protruding the drain connector into the connection chamber up to the drain opening in the tub floor, the entire area of the connection chamber remains filled with cleaning liquid during the period between two uses of the whirlpool tub, so that no sustainable dirt can be deposited in the entire area below the connection valve.

Nach einer besonderen Ausgestaltung der Erfindung ist die in Schließrichtung des Anschlußventils wirkende Schließfederkraft nur geringfügig größer als die Summe aller in Schließstellung des Anschlußventils auf den Ventilkörper des Anschlußventils in Öffnungsrichtung wirkenden Kräfte. Auf diese Weise genügt schon ein verhältnismäßig geringer Unterdruck in dem Rohrleitungssystem, um das Anschlußventil zu öffnen. Dieser kann bspw. durch ein impulsartiges Anschalten der Umwälzpumpe erzielt werden, wodurch die anfänglichen Haft- und Gleitreibungskräfte überwunden werden.According to a special embodiment of the invention, the closing spring force acting in the closing direction of the connecting valve is only slightly greater than the sum of all forces acting in the opening direction on the valve body of the connecting valve in the closing position of the connecting valve. In this way, a relatively low vacuum in the piping system is sufficient to open the connection valve. This can be achieved, for example, by switching on the circulation pump in a pulsed manner, as a result of which the initial static and sliding friction forces are overcome.

In Weiterbildung des Erfindungsgedankens umgibt der Ventilkörper des Anschlußventils den Abflußstutzen koaxial, so daß er eine besonders gute Führung auf dem Abflußstutzen erhält, wozu letzterer bspw. einen besonderen Führungsabschnitt an seinem Umfang aufweisen kann, an welchem eine hülsenartige Verlängerung des Ventilkörpers entlanggleitet.In a further development of the inventive concept, the valve body of the connection valve coaxially surrounds the drain connection, so that it receives particularly good guidance on the drain connection, for which purpose the latter can have, for example, a special guide section on its circumference along which a sleeve-like extension of the valve body slides.

Ein weiteres Erfindungsmerkmal besteht darin, daß die Schließfeder in einer Aussparung zwischen Abflußstutzen und Ventilkörper des Anschlußventils aufgenommen ist. Dadurch behält die Schließfeder, welche sich an einander gegenüberliegenden Schultern des Abflußstutzens und des Ventilkörpers des Anschlußventils abstützen kann, ihre Position sicher bei. Sie liegt außerdem geschützt innerhalb des Ventilkörpers.Another feature of the invention is that the closing spring is accommodated in a recess between the drain socket and the valve body of the connection valve. As a result, the closing spring, which can be supported on opposing shoulders of the drain connector and the valve body of the connection valve, securely maintains its position. It is also protected inside the valve body.

Wenn der Ventilkörper des Anschlußventils gemäß einem weiteren Erfindungsmerkmal an seinem oberen Ende einen aufknöpfbaren Dichtungsring mit nach radial außen und radial innen wegragenden kreisringförmigen Dichtungslippen aufweist, wird eine zuverlässige Dichtfunktion bei leichter Austauschbarkeit des Dichtungsringes erreicht.If, according to a further feature of the invention, the valve body of the connection valve has at its upper end a snap-on sealing ring with annular sealing lips projecting radially outward and radially inward, a reliable sealing function is achieved with the sealing ring being easy to replace.

Eine herstellungstechnische Vereinfachung kann dadurch erzielt werden, daß die konische Ventilsitzfläche des Abflußstutzens für das Anschlußventil von einem aufgeweiteten Rohrende des Abflußstutzens gebildet ist.A manufacturing simplification can be achieved in that the conical valve seat surface of the drain connector for the connecting valve is formed by a widened pipe end of the drain connector.

Das aufgeweitete Rohrende des Abflußstutzens kann vorteilhafterweise zugleich auch innen den Ventilsitz für das Abflußventil bilden.The widened pipe end of the drain connector can advantageously also form the inside of the valve seat for the drain valve.

Üblicherweise ist der Abflußöffnung eine Abdeckhaube zugeordnet. Bei der Erfindung kann diese bspw. gemeinsam mit dem Ventilkörper des Abflußventils mittels einer Betätigungseinrichtung heb- und senkbar angeordnet sein, so daß in Schließstellung die Abdeckhaube mit ihrem Abdeckabschnitt auf der Innenfläche des Wannenbodens anliegt, während er in Öffnungsstellung einen Ringspalt definierter Breite als Durchflußöffnung zur Abflußöffnung freigibt. Es sind aber auch andere Bewegungsmöglichkeiten der Abdeckbhaube denkbar.A cover is usually assigned to the drain opening. In the invention, this can, for example, be arranged together with the valve body of the drain valve by means of an actuating device so that it can be raised and lowered in the closed position, so that the cover with its cover section rests on the inner surface of the trough bottom, while in the open position it has an annular gap of a defined width as a flow opening Drain opening releases. However, other possibilities of movement of the cover hood are also conceivable.

Weitere Ziele, Merkmale, Vorteile und Anwendungsmöglichkeiten der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der Zeichnung. Dabei bilden alle beschriebenen und/oder bildlich dargestellten Merkmale für sich oder in beliebiger sinnvoller Kombination den Gegenstand der vorliegenden Erfindung, auch unabhängig von ihrer Zusammenfassung in den Ansprüchen oder deren Rückbeziehung.Further objectives, features, advantages and possible uses of the present invention result from the following description of an exemplary embodiment with reference to the drawing. All of the described and / or illustrated features, alone or in any meaningful combination, form the subject matter of the present invention, regardless of how they are summarized in the claims or their relationship.

Die einzige Figur der Zeichnung veranschaulicht im Vertikalschnitt eine die Erfindung aufweisende Whirlpoolwanne im Bereich der Abflußeinrichtung.The single figure of the drawing illustrates in vertical section a whirlpool tub having the invention in the area of the drainage device.

Die Abflußeinrichtung 10 ist im Bereich einer Aussparung 24 des Wannenbodens 1 vorgesehen. Zu diesem Zweck ist in die Aussparung 24 eine Ausflußhülse 25 eingelassen, welche eine Abflußöffnung 12 definiert. Die Abflußöffnung 12 mündet in eine Anschlußkammer 15, von welcher seitlich ein Rohrleitungssystem 2 abzweigt, welches für die Beaufschlagung wenigstens einer in das Wanneninnere mündenden (nicht dargestellten) Düse mit Wasser und/oder Luft bestimmt ist. Die Funktionsweise der Whirelpooleinrichtung ist die, daß bei Betrieb die Wassermenge, welche über die Whirlpooldüse in das Wanneninnere eingedüst wird, über die Abflußöffnung 12 wieder zurück in das Rohrleitungssystem 2 geführt wird, in welchem sich zu diesem Zweck eine (nicht dargestellte) Umwälzpumpe befindet. Zwischen Abflußöffnung 12 und der Austrittsöffnung 26 der Anschlußkammer 15 in das Rohrleitungssystem 2 befindet sich ein Anschlußventil 20. Das Anschlußventil 20 weist einen Ventilkörper 21 auf, welcher einen von unten in die Anschlußkammer 15 hineinragenden Abflußstutzen 16, welcher seinerseits in eine Abflußleitung 17 mündet, koaxial umgibt. Der Ventilkörper 21 ist mit einem nach unten ragenden Hülsenabschnitt 27 an einem Führungsabschnitt 23 des Abflußstutzens 16 geführt. An seinem oberen Ende trägt der Ventilkörper 21 des Anschlußventils 20 einen im radialen Querschnitt U-förmigen, auf das obere Ende des Ventilkörpers 21 wirkenden Dichtungsring 22, von welchem nach radial außen und nach radial innen Dichtungslippen 7 bzw. 8 wegragen. Die Dichtungslippen 7 und 8 arbeiten mit Ventilsitzflächen 4 und 5 zusammen, welche einerseits an der Anschlußkammer 14, andererseits an dem Abflußstutzen 16 gebildet sind.The drain device 10 is provided in the region of a recess 24 in the tub base 1. For this purpose, a discharge sleeve 25 is inserted into the recess 24, which defines a drain opening 12. The drain opening 12 opens into a connection chamber 15, from which laterally a piping system 2 branches off, which is intended for the supply of water and / or air to at least one nozzle (not shown) which opens into the interior of the tub. The functionality of the whirlpool pool device is that during operation the amount of water which is injected into the interior of the tub via the whirl pool nozzle is returned via the drain opening 12 back into the pipeline system 2, in which a circulation pump (not shown) is located for this purpose. Between the drain opening 12 and the outlet opening 26 of the connection chamber 15 into the piping system 2 there is a connection valve 20. The connection valve 20 has a valve body 21 which coaxially coaxially projects into the connection chamber 15 from below, which in turn opens into a drain line 17 surrounds. The valve body 21 is guided with a downwardly projecting sleeve section 27 on a guide section 23 of the drain connector 16. At its upper end, the valve body 21 of the connection valve 20 carries a sealing ring 22, which has a U-shaped radial cross section and acts on the upper end of the valve body 21, from which sealing lips 7 and 8 protrude radially outwards and radially inwards. The sealing lips 7 and 8 work together with valve seat surfaces 4 and 5, which are formed on the one hand on the connection chamber 14, and on the other hand on the drain port 16.

Der Ventilkörper 21 des Anschlußventils 20 wird von einer Schließfeder 3 in Schließrichtung gedrückt, so daß die Dichtungslippen 7 und 8 an die einander konisch zugeneigten, kegelstumpfmantelförmigen Ventilsitzflächen 4, 5 angedrückt werden. Die als Wendelfeder ausgebildete Feder 3 ist in einer den Abflußstutzen 16 koaxial umgebenden Aussparung 6 zwischen Abflußstutzen 16 und Ventilkörper 21 des Anschlußventils 20 ebenfalls koaxial zum Anschlußstutzen 16 und diesen umgebend angeordnet, indem sie sich auf ringflächenförmigen Schultern 28, 29 des Abflußstutzens 16 bzw. des Ventilkörpers 21 abstützt. Die Konizität der Ventilsitzfläche 5 am oberen Ende des Abflußstutzens 16 ist durch ein aufgeweitetes Rohrende des Abflußstutzens 16 gebildet. Auf diese Weise ist gleichzeitig ein geeigneter Ventilsitz 9 in dem Abflußstutzen 16 verwirklicht, an welchen ein Ventilkörper 11 eines Abflußventils 18 dichtend anstellbar ist. Dies geschieht bspw. mittels einer im dargestellten Falle stabförmigen Betätigungseinrichtung 19, deren Verstellmöglichkeit mit einem Doppelpfeil angedeutet ist.The valve body 21 of the connecting valve 20 is pressed by a closing spring 3 in the closing direction, so that the sealing lips 7 and 8 are pressed against the conically inclined, frustoconical valve seat surfaces 4, 5. The spring 3 designed as a helical spring is arranged in a recess 6 coaxially surrounding the drain connector 16 between the drain connector 16 and the valve body 21 of the connection valve 20, also coaxially with the connector 16 and surrounding it, by being on annular shoulders 28, 29 of the drain connector 16 and the Valve body 21 supports. The taper of the valve seat surface 5 at the upper end of the drain connector 16 is formed by a widened pipe end of the drain connector 16. In this way, a suitable valve seat 9 is simultaneously realized in the drain connection 16, against which a valve body 11 of a drain valve 18 can be sealingly adjusted. This is done, for example, by means of an actuating device 19 which is rod-shaped in the case shown and whose adjustment possibility is indicated by a double arrow.

Mit der Betätigungseinrichtung 19 verstellt sich in dem dargestellten Ausführungsbeispiel auch eine Abdeckhaube 13, welche mit ihrem die Abflußöffnung 12 überkragenden Abdeckabschnitt mit der Innenfläche des Wannenbodens 1 einen je nach Höhenstellung mehr oder weniger breiten definierten Ringspalt als Durchtrittsöffnung freigibt.With the actuating device 19, a cover 13 is also adjusted in the exemplary embodiment shown, which with its cover section projecting over the drain opening 12 with the inner surface of the trough base 1 releases a more or less wide defined annular gap as a passage opening depending on the height position.

Aufgrund des Umstandes, daß das Anschlußventil 20 einen an dem Abflußstutzen 16 geführten Ventilkörper 21 aufweist, welcher unter der Wirkung der Schließfeder 3 in Richtung seines Dichtsitzes gedrückt wird und daß der Dichtsitz von sich in Schließrichtung konisch verengenden Ventilsitzflächen 4,5 der Anschlußkammerwandung 14 bzw. des Abflußstutzens 16 gebildet ist, hebt sich der Ventilkörper 21 bei einem plötzlichen Anschalten der Umwälzpumpe in dem Rohrleitungssystem 2 gegen die Wirkung der mit geringer Federkraft ausgestatteten Schließfeder 3 sofort von der Ventilsitzfläche 4, 5 ab. Aufgrund des sich vergrößernden Öffnungsquerschnittes des Anschlußventils 20 gelangt der Ventilkörper 21 des Anschlußventils 20 schnell unter Mitwirkung der Strömung des z.B. über radiale Kanäle der Abdeckhaube 13 in die Abflußöffnung 12 eintretenden Wassers schnell in die gestrichelt dargestellte Öffnungslage, welche bei Betrieb der Whirlpooleinrichtung beibehalten wird. Nach Abschalten der Umwälzpumpe und Abbau des Unterdrucks in dem sich an die Austrittsöfnung 26 anschließenden Teil des Rohrleitungssystems 2 wird der Ventilkörper 21 des Anschlußventils 20 sofort wieder in die dargestellte höhere Schließstellung gebracht. Der bei Öffnen des Abflußventils 18 oberhalb des Ventilkörpers 21 entstehende Unterdruck kann das Anschlußventil 20 ersichtlich nicht öffnen, da der Ventilkörper 21 nur noch mehr in seinen Dichtsitz gesogen wird. Auf diese Weise ist das Rohrleitungssystem 2 beim Ableiten des Badewassers in die Abflußleitung 17 hermetisch abgeschlossen. Dem Innenraum des Rohrleitungssystems 2 kann dann eine Reinigungs- und Desinfektionslösung zugegeben werden, welche bis zur nächsten Benutzung der Whirlpoolwanne darin stehen bleibe kann, wodurch auch der Innenraum der Anschlußkammer 15 mit Reinigungs- bzw. Desinfektionsflüssigkeit beaufschlagt bleibt.Due to the fact that the connection valve 20 has a valve body 21 which is guided on the discharge connection 16 and which is pressed under the action of the closing spring 3 in the direction of its sealing seat and that the sealing seat is constricted in the closing direction by valve seat surfaces 4, 5 of the connection chamber wall 14 or of the drainage pipe 16 is formed, the valve body 21 immediately lifts off from the valve seat surface 4, 5 when the circulation pump in the pipeline system 2 is suddenly switched on against the action of the closing spring 3 which is equipped with low spring force. Due to the increasing opening cross-section of the connection valve 20, the valve body 21 of the connection valve 20 quickly reaches the opening position shown in dashed lines, with the participation of the flow of water entering the drain opening 12, for example via radial channels of the cover 13, which is maintained during operation of the whirlpool device. After the circulation pump has been switched off and the negative pressure in the part of the pipeline system 2 adjoining the outlet opening 26, the valve body 21 of the connecting valve 20 is immediately brought back into the higher closed position shown. The negative pressure arising above the valve body 21 when the drain valve 18 is opened cannot be seen to open the connection valve 20, since the valve body 21 is only drawn more into its sealing seat. In this way, the pipeline system 2 is hermetically sealed when the bathing water is drained into the drain line 17. The interior A cleaning and disinfection solution can then be added to the piping system 2, which solution can remain in it until the next use of the whirlpool bath, as a result of which cleaning and disinfection liquid also remains applied to the interior of the connection chamber 15.
