Description

Die Erfindung bezieht sich auf eine Whirlpoolwanne mit Rohrleitungssystem und Wasserstrahldüse, mit einem in der Wannenwandung angeordneten Gehäuse, an welches eine Druckwasserleitung und eine Luftzufuhrleitung angeschlossen sind, mit einem mit einem Düsenkanal in eine Strahlaustrittsöffnung mündenden, zur Veränderung der Strahlaustrittsrichtung verstellbaren Düsenkörper, der in eine Stellung verstellbar ist, in welcher die Strahlaustrittsöffnung tiefer als eine Wassereintrittsöffnung des Düsenkanals liegt, wobei die Wassereintrittsöffnung in einen Wasserzufuhrkanal einer Stirnwand des Düsenkörpers mündet und eine Lufteintrittsöffnung des Düsenkörpers in Strömungsverbindung mit der Luftzufuhrleitung steht.The invention relates to a whirlpool tub with a piping system and water jet nozzle, with a housing arranged in the tub wall, to which a pressurized water line and an air supply line are connected, with a nozzle body which opens into a jet outlet opening with a nozzle channel and is adjustable in order to change the direction of the jet outlet Position is adjustable, in which the jet outlet opening is lower than a water inlet opening of the nozzle channel, the water inlet opening opening into a water supply channel of an end wall of the nozzle body and an air inlet opening of the nozzle body being in flow connection with the air supply line.

Insbesondere wenn die Wasserstrahldüse mit Hilfe eines eine Abflußeinrichtung der Whirlpoolwanne mit der Wasserstrahldüse verbindenden Rohrleitungssystems, unter Verwendung des Badewassers betrieben wird, besteht das Problem der Verunreinigung der Wasserstrahldüse insbesondere durch im Düsenbereich während der Dauer der Nichthenutzung der Whirlpoolwanne stehenbleibendes Restwasser. Es ist zwar bereits vorgeschlagen worden, dem in dem Rohrleitungssystem für die Zeit der Nichtbenutzung der Whirlpoolwanne in dem Rohrleitungssystem stehenbleibenden Badewasser Reinigungs- und/oder Desinfektionsmittel zuzuführen, welche die hinreichende Hygiene im Bereich des Rohrleitungssystems gewährleisten. Die Reinigungs- und/oder Desinfektionsmittel gelangen bei derartigen bekannten Systemen jedoch nicht in den Bereich des ungewollt in der Wasserstrahldüse stehendenbleibenden Restwassers.In particular, if the water jet nozzle is operated using a tubing system connecting a drain device of the whirlpool tub to the water jet nozzle, using the bath water, there is the problem of contamination of the water jet nozzle, in particular, by residual water remaining in the nozzle area during the period of non-use of the whirlpool tub. It has already been suggested that in the piping system for the time when the whirlpool tub is not being used in the piping system, supplying bathing water with cleaning agents and / or disinfectants which ensure adequate hygiene in the area of the piping system. In such known systems, however, the cleaning agents and / or disinfectants do not reach the area of the residual water which is inadvertently left in the water jet nozzle.

Aus der US-A-4 542 854 ist eine Whirlpoolwanne gemäß dem Oberbegriff des Anspruchs 1 bekannt.A whirlpool tub according to the preamble of claim 1 is known from US-A-4 542 854.

Bei einer weiteren aus der US-A-3 890 655 bekannten Düse kann auch in Ausfließstellung des Düsenkörpers nicht sämtliches Restwasser aus der Whirlpoolwanne abfließen. Ferner sind dort die Strahlausbildung und die Ausnutzung des Venturi-Effektes unbefriedigend.In a further nozzle known from US Pat. No. 3,890,655, not all of the residual water can flow out of the whirlpool tub even in the outflow position of the nozzle body. Furthermore, the beam formation and the exploitation of the Venturi effect are unsatisfactory.

Bei der Luftsprudeldüse nach der US-A-4 408 721 ist der Düsenkörper nur zusammen mit einem Kugelelement verstellbar. Restwasser bleibt in allen Stellungen des Düsenkörpers jedenfalls in der das Düsenrohr umgebenden Kammer stehen, weil diese sich nach innen hin konisch erweitert.In the air jet nozzle according to US-A-4 408 721, the nozzle body can only be adjusted together with a spherical element. Residual water remains in all positions of the nozzle body in any case in the chamber surrounding the nozzle tube, because this widens conically inwards.

Bei dem Wasserbecken mit Luftsprudelvorrichtung nach der EP-B-0 209 646 sind die Luft- und Wasserführung derart gestaltet, daß Luft oder Wasser oder ein Wasser-/Luftgemisch in das Innenbecken eingestrahlt werden kann. Die Kanäle und Leitungen für die Wasser- und Luftzuführung sind so angeordnet, daß sie sich nach Benutzung vollständig entleeren. Ein Eindringen von Seifenresten oder Badewasser in das Zuführungssystem soll dadurch verhindert werden, daß der Wasser- und
Luftauslaßdüse Rückschlagventile zugeordnet sind, die nur während des Massagebetriebes geöffnet sind.In the water basin with air bubble device according to EP-B-0 209 646, the air and water guidance are designed in such a way that air or water or a water / air mixture can be blasted into the inner basin. The channels and lines for the water and air supply are arranged so that they empty completely after use. Penetration of soap residues or bath water into the feed system should be prevented by the water and
Air outlet nozzle check valves are assigned that are only open during massage operation.

Aufgabe der vorliegenden Erfindung ist es, eine Whirlpoolwanne mit einer Wasserstrahldüse der eingangs genannten Art so weiterzubilden, daß die Wasserstrahldüse selbständig mit dem Ablassen des Badewassers aus der Whirlpoolwanne nach deren Benutzung entleerbar ist.The object of the present invention is to develop a whirlpool tub with a water jet nozzle of the type mentioned at the outset such that the water jet nozzle can be emptied automatically when the bath water is drained from the whirlpool tub after it has been used.

Diese Aufgabe wird bei einer Whirlpoolwanne der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß der Düsenkörper in eine Ausfließstellung verstellbar ist, in der die Wassereintrittsöffnung höher als die Druckwasserleitung liegt und die Lufteintrittsöffnung sich an dem oberen Umfang des Düsenkörpers befindet.This object is achieved according to the invention in a whirlpool tub of the type mentioned at the outset in that the nozzle body is adjustable into an outflow position in which the water inlet opening is higher than the pressurized water line and the air inlet opening is located on the upper periphery of the nozzle body.

Auf diese Weise wird bei guter Strahlausbildung und Ausnutzung des Venturi-Effektes erreicht, daß Badewasser während der Nichtbenutzung der Whirlpoolwanne nur in solchen Bereichen des Rohrleitungsystems, welches die Druckwasserleitung einschließt, stehenbleibt, zu welchen auch die dem Rohrleitungssystem zugegebenen Reinigungs und/oder Desinfektionsmittel gelangen. Durch die besondere Anordnung von Strahlaustrittsöffnung, Wassereintrittsöffnung und Druckwasserleitung zueinander wird gewährleistet, daß mit dem Ablassen des Badewassers aus der Whirlpoolwanne nsch deren Benutzung auch sämtliches Restwasser aus der Wasserstrahldüse herausfließen kann.In this way, with good jet formation and exploitation of the Venturi effect, bath water, when the whirlpool tub is not in use, only remains in those areas of the pipeline system which include the pressurized water line, to which the cleaning agents and / or disinfectants added to the pipeline system also reach. The special arrangement of the jet outlet opening, water inlet opening and pressurized water line in relation to one another ensures that when the bath water is drained from the whirlpool bath, its use, all residual water can flow out of the water jet nozzle.

Eine besonders einfache konstruktive Verwirklichung des Erfindungsgedankens wird dann erreicht, wenn der Düsenkörper in dem Gehäuse um eine Drehachse drehbar gelagert ist und die Austrittsachse des Düsenkanals in einem Winkel zur Drehachse, d.h. schräg zur Horizontalen verläuft. Auf diese Weise wird sichergestellt, daß durch einfaches Drehen des Düsenkörpers dieser immer in eine Drehlage gebracht werden kann, in welcher das Restwasser aus der Wasserstrahldüse vollständig herausfließt. Verläuft die Drehachse des Düsenkörpers nicht horizontal, so ist die Austrittsachse des Düsenkanals jedenfalls so anzuordnen, daß sie schräg zur Horizontalen verläuft, um das Auslaufen des Restwassers stets zu gewährleisten.A particularly simple constructive realization of the inventive concept is achieved when the nozzle body is rotatably mounted in the housing about an axis of rotation and the Exit axis of the nozzle channel at an angle to the axis of rotation, ie obliquely to the horizontal. In this way it is ensured that by simply rotating the nozzle body, it can always be brought into a rotational position in which the residual water flows out of the water jet nozzle completely. If the axis of rotation of the nozzle body is not horizontal, the outlet axis of the nozzle channel must in any case be arranged so that it runs obliquely to the horizontal in order to always ensure that the residual water runs out.

Die Wassereintrittsöffnung des Düsenkörpers ist vorzugsweise außermittig zur Drehachse im Düsenkörper angeordnet, so daß sie durch Drehen des Düsenkörpers aus ihrer obersten Lage, in welcher die Austrittsachse des Düsenkanals größtmögliche Schräge gegenüber der Horizontalen und die Wassereintrittsöffnung auch den größtmöglichen Abstand von der Druckwasserleitung hat, in eine Lage verdreht werden kann, in welcher die Wassereintrittsöffnung näher bei der Druckwasserleitung, also tiefer liegt.The water inlet opening of the nozzle body is preferably arranged eccentrically to the axis of rotation in the nozzle body, so that by rotating the nozzle body from its uppermost position, in which the outlet axis of the nozzle channel has the greatest possible inclination with respect to the horizontal and the water inlet opening also has the greatest possible distance from the pressurized water line Can be rotated position in which the water inlet opening is closer to the pressurized water line, that is, lower.

Bei einer besonders vorteilhaften Ausgestaltung der Erfindung steht die Wassereintrittsöffnung in jeder Drehstellung des Düsenkörpers mit der Druckwasserleitung in Strömungsverbindung. Hierdurch wird gewährleistet, daß die Strahlaustrittsrichtung durch Veränderung der Stellung des Düsenkörpers während des Whirlpoolbetriebes über einen möglichst großen Winkelbereich verstellt werden kann.In a particularly advantageous embodiment of the invention, the water inlet opening is in flow connection with the pressurized water line in every rotational position of the nozzle body. This ensures that the jet exit direction can be adjusted over a large angular range by changing the position of the nozzle body during whirlpool operation.

Eine sichere Funktion der erfindungsgemäßen Whirlpoolwanne wird auf einfache Weise dann gewährleistet, wenn der Düsenkörper mit im wesentlichen zylindrischen Führungsflächen in dem Gehäuse bzw. in einer in dem Gehäuse gelagerten Führungshülse drehbar gelagert ist und daß die Wassereintrittsöffnung
in einer Stirnwand des Düsenkörpers liegt. Hierdurch wird eine einfache Betätigungsmöglichkeit des Düsenkörpers mit einer einfachen Druckwasserführung in optimaler Weise kombiniert.Safe functioning of the whirlpool tub according to the invention is ensured in a simple manner if the nozzle body is rotatably mounted with essentially cylindrical guide surfaces in the housing or in a guide sleeve mounted in the housing and that the water inlet opening
lies in an end wall of the nozzle body. In this way, a simple actuation option of the nozzle body is combined in an optimal manner with a simple pressure water supply.

Dabei kann die Führungshülse stirnseitig eine Wasserdurchlaßöffnung aufweisen, welche einerseits mit der Druckwasserleitung und andererseits in jeder Drehstellung des Düsenkörpers mit dessen Wassereintrittsöffnung in Strömungsverbindung steht. Dies kann auf einfache Weise dadurch gewährleistet werden, daß praktisch die gesamte Bodenwand der Führungshülse von der Wasserdurchlaßöffnung durchsetzt ist und die Druckwasserleitung über einen die gesamte Wasserdurchlaßöffnung überdeckenden Stutzen an das Gehäuse angeschlossen ist, welches die Führungshülse aufnimmt. Solange sich die Wassereintrittsöffnung des Düsenkörpers oberhalb der horizontalen Mittelebene der mit horizontaler Drehachse angeordneten Führungshülse befindet, ist ein Abfließen von Restwasser aus dem Düsenkanal nach Benutzung der Whirlpoolwanne gewährleistet.The guide sleeve can have a water passage opening on the end face, which is on the one hand in flow connection with the pressurized water line and on the other hand in every rotational position of the nozzle body with its water inlet opening. This can be ensured in a simple manner in that practically the entire bottom wall of the guide sleeve is penetrated by the water passage opening and the pressurized water line is connected to the housing, which receives the guide sleeve, via a nozzle covering the entire water passage opening. As long as the water inlet opening of the nozzle body is above the horizontal central plane of the guide sleeve arranged with the horizontal axis of rotation, residual water is guaranteed to flow out of the nozzle channel after use of the whirlpool tub.

Bei einer besonders einfachen und funktionsgerechten Ausgestaltung der Erfindung weist der Düsenkanal über seine gesamte Länge eine gerade Austrittsachse auf und die Strahlaustrittsöffnung liegt außermittig zur Drehachse des Düsenkörpers. Hierdurch ist sichergestellt, daß in der Abfließdrehstellung des Düsenkörpers Wassereintrittsöffnung und Strahlaustrittsöffnung des Düsenkörpers einen größtmöglichen Höhenunterschied aufweisen, wobei die Austrittsachse des Düsenkanals zur Gewährleistung eines möglichst kräftigen Wasseraustrittsstrahls gerade verläuft.In a particularly simple and functional design of the invention, the nozzle channel has a straight outlet axis over its entire length and the jet outlet opening is located eccentrically to the axis of rotation of the nozzle body. This ensures that in the outflow rotational position of the nozzle body, the water inlet opening and the jet outlet opening of the nozzle body have the greatest possible height difference, the outlet axis of the nozzle channel running straight to ensure the strongest possible water outlet jet.

Die Strömungsführung des Badewassers im Düsenbereich und das Abfließen von Restwasser wird noch weiter verbessert, wenn der Wasserzufuhrkanal koaxial zur Austrittsachse des Düsenkanals liegt. Auf diese Weise verläuft auch der Wasserzufuhrkanal, jedenfalls in der Abfließdrehstellung des Düsenkörpers, schräg zur Horizontalen, so daß auch in dem Wasserzufuhrkanal kein Restwasser stehenbleiben kann, wenn die Whirlpooleinrichtung abgeschaltet und das Badewasser aus der Whirlpoolwanne abgelassen worden ist.The flow of the bathing water in the nozzle area and the drainage of residual water is further improved if the water supply channel is coaxial with the outlet axis of the nozzle channel. In this way, the water supply channel, at least in the discharge rotational position of the nozzle body, runs obliquely to the horizontal, so that no residual water can remain in the water supply channel when the whirlpool device is switched off and the bath water has been drained from the whirlpool tub.

Wenn mit dem Wasseraustrittsstrahl auch Luft mitgerissen werden soll, um den Massageeffekt derartiger Whirlpooldüsen zu verbessern, weist der Düsenkörper nach der Erfindung auch eine Lufteintrittsöffnung auf, welche benachbart zum Wassereintritt in den Düsenkanal mündet. Hierdurch bildet sich zwangsläufig ein Venturi-Düseneffekt aus, welcher das Mitreißen der gewünsch ten Luftmenge mit dem in den Düsenkörper eintretenden Druckwasser gewährleistet. Die Lufteintrittsöffnung sollte, vorzugsweise senkrecht, von oben in den Düsenkörper münden, so daß auch in diesem Bereich und insbesondere auch in dem sich an die Lufteintrittsöffnung anschließenden Luftanschlußstutzen kein Restwasser stehenbleiben kann, wobei selbstverständlich die Luftzufuhrleitung, jedenfalls im Bereich der Wasserstrahldüse, oberhalb des Gehäuses derselben verläuft.If air is also to be entrained with the water outlet jet in order to improve the massage effect of such whirl pool nozzles, the nozzle body according to the invention also has an air inlet opening which opens into the nozzle channel adjacent to the water inlet. This inevitably forms a venturi nozzle effect, which ensures entrainment of the desired amount of air with the pressurized water entering the nozzle body. The air inlet opening should, preferably vertically, open into the nozzle body from above, so that no residual water can remain in this area and in particular also in the air connection piece adjoining the air inlet opening, whereby of course the air supply line, at least in the area of the water jet nozzle, above the housing the same goes.

Auf besonders einfache Weise kann das erwähnte Venturi-Prinzip bei der Erfindung dadurch verwirklicht sein, daß der Lufteintritt in den Düsenkanal in einem Winkel von vorzugsweise zwischen 80° und 110° zur Austrittsachse des Düsenkanals erfolgt.In a particularly simple manner, the venturi principle mentioned can be implemented in the invention in that the air enters the nozzle duct at an angle of preferably between 80 ° and 110 ° to the outlet axis of the nozzle duct.

Die Luftzufuhrleitung mündet gemäß einer weiteren besonderen Ausgestaltung der Erfindung entweder unmittelbar oder über einen Umfangskanal in die Lufteintrittsöffnung. Falls in jeder Drehstellung des Düsenkörpers Luft zu dem Wasserstrahl zuführbar sein soll, müßte im ersten Fall die Lufteintrittsöffnung einen entsprechenden Umfangsbereich einnehmen, während bei der zweiten Alternative die Lufteintittsöffnung eine kreiszylindrische Bohrung oder Ausnehmung des Düsenkörpers sein kann, während der Umfangskanal den gewünschten Umfangsbereich einnimmt.According to a further special embodiment of the invention, the air supply line opens into the air inlet opening either directly or via a circumferential channel. If air can be supplied to the water jet in any rotational position of the nozzle body in the first case, the air inlet opening would have to take up a corresponding peripheral area, while in the second alternative the air inlet opening could be a circular cylindrical bore or recess in the nozzle body, while the peripheral channel takes up the desired peripheral area.

Die Montage und Instandhaltung der erfindungsgemäßen Whirlpoolwanne kann bei Neueinbau, Verschleiß oder Defekt des Düsenkörpers auf einfache Weise dadurch gewährleistet werden, daß dieser mittels einer an dem Gehäuse unmittelbar oder mittelbar festlegbaren Abschlußkappe austauschbar in dem Gehäuse bzw. der Führungshülse gehalten ist.The assembly and maintenance of the whirlpool tub according to the invention can be ensured in a simple manner in the case of new installation, wear or defect of the nozzle body in that it is held interchangeably in the housing or the guide sleeve by means of an end cap which can be fixed directly or indirectly.

Damit der Düsenkörper nicht nur radial in dem Gehäuse bzw. der Führungshülse sondern auch axial zuverlässig geführt ist, ist der Düsenkörper vorzugsweise zwischen Anschlagschultern des Gehäuses bzw. der Führungshülse einerseits und der Abschlußkappe andererseits axial aufgenommen.So that the nozzle body is not only guided radially in the housing or the guide sleeve but also axially reliably, the nozzle body is preferably axially received between the stop shoulders of the housing or the guide sleeve on the one hand and the end cap on the other.

Um die Strahlaustrittsrichtung einfach verstellen zu können, hat der Düsenkörper vorzugsweise wanneninnenseitig einen Betätigungsabschnitt.In order to be able to easily adjust the jet exit direction, the nozzle body preferably has an actuating section on the inside of the tub.

Die Wasserstrahldüse 1 gemäß Fig. 1 weist ein im wesentlichen zylindrisches Gehäuse 10 auf, welches mit einer mit Außengewinde versehenen Befestigungshülse 11 in einer Aussparung 6 eines Wandabschnitts 7 des Wannenbodens oder einer Wannenseitenwand einer Whirlpoolwanne dichtend festgelegt ist. Das Gehäuse 10 ist in dem dargestellten Fall Teil eines Rohrleitungssystems und stirnseitig über einen Wasseranschlußstutzen 13 mit einer Druckwasserleitung 15 und in seinem oberen Mantelbereich über einen Luftanschlußstutzen 14 mit einer Luftzufuhrleitung 16 verbunden. Die Befestigungshülse 11 liegt mit einem erweiterten Flansch 8 wanneninnenseitig an der Oberfläche 33 des Wandabschnitts 7 an. Das Gehäuse 10 ragt aus unten noch näher zu erläuternden Gründen nur über einen Teil der Länge der Befestigungshülse 11 in diese hinein und zwar bis zu einem Anschlagring 12. In dem Gehäuse 10 ist eine Führungshülse 17 drehfest angeordnet. Die Führungshülse 17 hat in ihrem Bodenbereich eine Wasserdurchlaßöffnung 18, welche über den Wasseranschlußstutzen 13 mit der Druckwasserleitung 15 in Strömungsverbindung steht, sowie im oberen Bereich ihres Mantels eine Luftdurchlaßöffnung 22, welche über den Luftanschlußstutzen 14 mit der Luftzufuhrleitung 16 in Strömungsverbindung steht. In der Führungshülse 17 ist ein mit zylindrischen Führungsflächen versehener Düsenkörper 20 um eine horizontale Drehachse D drehbar gelagert. Die axiale Positionierung des Düsenkörpers 20 in der Führungshülse 17 und dem Gehäuse 10 erfolgt dadurch, daß der Düsenkörper 20 mit einer dem Wanneninnenraum 32 abgewandten Schulter an einer wanneninnenseitigen Anschlagschulter 4 der Führungshülse 17 und mit seinem wanneninnenseitigen Ende an einer Anschlagschulter 5 anliegt, welche an einer Abschlußkappe 28 ausgebildet ist, die in die Befestigungshülse 11 eingeschraubt ist und den Flansch 8 der Befestigungshülse 11 mit einem Abdeckflansch 9 überdeckt. Der Gewindeabschnitt 29 der Abschlußkappe 28 endet vor dem dem Wanneninnenraum 32 zugewandten stirnseitigen Ende des Gehäuses 10. Der wanneninnenseitige Abschnitt des Düsenkörpers 20 ist gegen das Gehäuse 10 mittels Dichtungsring 26, der Mantel des Gehäuses 10 gegenüber der Befestigungshülse 11 mittels eines Dichtungsringes 30 und der Flansch 8 der Befestigungshülse 11 gegenüber der dem Wanneninnenraum 32 zugewandten Oberfläche 33 des Wandabschnitts 7 mittels eines Dichtungsrings abgedichtet. In dem Düsenkörper 20 ist ein Düsenkanal 23 mit gerader Austrittsachse K ausgebildet, welche unter einem Winkel α gegenüber der horizontalen Drehachse D verläuft. In das dem Wanneninnenraum 32 abgewandte Ende des Düsenkanals 23 mündet ein koaxial zu dem Düsenkanal 23 in der Stirnwand 2 vorgesehener Wasserzufuhrkanal 21, welcher über eine Wassereintrittsöffnung 25 mit der Wasserdurchlaßöffnung 18 im Boden der Führungshülse 17 in Strömungsverbindung steht. Der Düsenkanal 23 mündet über eine Strahlaustrittsöffnung 24 in den Wanneninnenraum 32. In der in Fig. 1 dargestellten Abfließdrehlage des Düsenkörpers 20 liegt die Strahlaustrittsöffnung 24 tiefer als die Wassereintrittsöffnung 25 des Düsenkanals 23 und letztere höher als die Druckwasserleitung 15. Auf diese weise kann in dieser Abfließdrehstellung das Restwasser sowohl aus dem Düsenkanal 23 als auch aus dem Wasserzufuhrkanal 21 abfließen, wenn die Whirlpooleinrichtung abgeschaltet ist und das Badewasser aus dem Wanneninnenraum 32 abgelassen wird. Durch die drehbare Lagerung des Düsenkörpers 20 und die Schrägneigung der Austrittsachse K des Düsenkanals 23 gegenüber der Drehachse D ist die Strahlaustrittsrichtung veränderbar.1 has an essentially cylindrical housing 10, which is fixed with a fastening sleeve 11 provided with an external thread in a recess 6 of a wall section 7 of the tub floor or a tub side wall of a whirlpool tub. In the illustrated case, the housing 10 is part of a pipeline system and is connected at the end face to a pressurized water line 15 via a water connection stub 13 and in its upper jacket region via an air connection stub 14 to an air supply line 16. The fastening sleeve 11 lies with an enlarged flange 8 on the inside of the tub on the surface 33 of the wall section 7. For reasons to be explained in more detail below, the housing 10 projects into the fastening sleeve 11 only over part of the length thereof, namely up to a stop ring 12. A guide sleeve 17 is arranged in the housing 10 in a rotationally fixed manner. The guide sleeve 17 has in its bottom region a water passage opening 18 which is in flow connection via the water connection piece 13 with the pressurized water line 15, and in the upper region of its jacket an air passage opening 22 which is in flow connection with the air supply line 16 via the air connection piece 14. In the guide sleeve 17, a nozzle body 20 provided with cylindrical guide surfaces is rotatably mounted about a horizontal axis of rotation D. The axial positioning of the nozzle body 20 in the guide sleeve 17 and the housing 10 takes place in that the nozzle body 20 with a the shoulder facing away from the tub interior 32 abuts on a tub-side stop shoulder 4 of the guide sleeve 17 and with its tub-inside end on a stop shoulder 5, which is formed on an end cap 28 which is screwed into the fastening sleeve 11 and the flange 8 of the fastening sleeve 11 with a cover flange 9 covered. The threaded section 29 of the end cap 28 ends in front of the front end of the housing 10 facing the tub interior 32. The tub-side section of the nozzle body 20 is against the housing 10 by means of a sealing ring 26, the casing of the housing 10 relative to the fastening sleeve 11 by means of a sealing ring 30 and the flange 8 of the fastening sleeve 11 is sealed off from the surface 33 of the wall section 7 facing the tub interior 32 by means of a sealing ring. In the nozzle body 20, a nozzle channel 23 is formed with a straight exit axis K, which extends at an angle α with respect to the horizontal axis of rotation D. In the end of the nozzle channel 23 facing away from the tub interior 32, a water supply channel 21, which is provided coaxially to the nozzle channel 23 in the end wall 2, opens and is in flow connection via a water inlet opening 25 with the water passage opening 18 in the bottom of the guide sleeve 17. The nozzle channel 23 opens into the tub interior 32 via a jet outlet opening 24. In the outflow rotational position of the nozzle body 20 shown in FIG. 1, the jet outlet opening 24 lies deeper than the water inlet opening 25 of the nozzle channel 23 and the latter higher than the pressurized water line 15 Outflow rotational position, the residual water flows out of both the nozzle channel 23 and the water supply channel 21 when the whirlpool device is switched off and the bath water is drained from the tub interior 32. The jet outlet direction can be changed by the rotatable mounting of the nozzle body 20 and the inclined inclination of the outlet axis K of the nozzle channel 23 with respect to the axis of rotation D.

In seinem Mantelbereich hat der Düsenkörper 20 ferner eine Lufteintrittsöffnung 19, welche sich in der dargestellten Abfließdrehstellung des Düsenkörpers 20 mit der Luftdurchlaßöffnung 22 der Führungshülse 17 deckt. In dieser Drehstellung kann das Restwasser auch aus diesem Bereich und dem sich anschließenden Luftanschlußstutzen 14 vollständig abfließen. In anderen Drehstellungen kann die Luftdurchlaßöffnung 22 der Führungshülse 17 über einen Umlaufkanal 3 mit der Lufteintrittsöffnung 19 des Düsenkörpers 20 in Strömungsverbindung stehen, so daß dem Düsenkanal 23 in jeder Drehlage des Düsenkörpers 20 Luft zugeführt werden kann. Ebenso kann dem Düsenkanal 23 in jeder Drehlage des Düsenkörpers 20 Druckwasser zugeführt werden, weil die Wasserdurchlaßöffnung 18 im Bodenbereich der Führungshülse 17 so gestaltet und so groß bemessen ist, daß die Wassereintrittsöffnung 25 des Düsenkörpers 20 in jeder Drehstellung mit letzterer in Strömungsverbindung steht. Die Lufteintrittsöffnung 19 mündet unmittelbar in Nachbarschaft des Wasserzufuhrkanals 21 in den Düsenkanal 23, und zwar unter einem Winkel β zur Austrittsachse K, so daß ein Venturi-Effekt entsteht und das in den Düsenkanal 23 über den Wasserzufuhrkanal 21 eintretende Druckwasser Luft aus der Luftzufuhrleitung 16 mitreißt.In its jacket area, the nozzle body 20 also has an air inlet opening 19 which, in the outflow rotational position of the nozzle body 20 shown, coincides with the air passage opening 22 of the guide sleeve 17. In this rotational position, the residual water can also flow completely out of this area and the adjoining air connection piece 14. In other rotational positions, the air passage opening 22 of the guide sleeve 17 can be in flow connection with the air inlet opening 19 of the nozzle body 20 via a circulation channel 3, so that air can be supplied to the nozzle channel 23 in any rotational position of the nozzle body 20. Likewise, pressurized water can be supplied to the nozzle channel 23 in any rotational position of the nozzle body 20 because the water passage opening 18 in the bottom region of the guide sleeve 17 is designed and dimensioned so large that the water inlet opening 25 of the nozzle body 20 is in flow connection with the latter in every rotational position. The air inlet opening 19 opens directly in the vicinity of the water supply channel 21 into the nozzle channel 23, at an angle β to the outlet axis K, so that a venturi effect arises and the pressurized water entering the nozzle channel 23 via the water supply channel 21 entrains air from the air supply line 16 .

Am wanneninnenseitigen Ende ist an dem Düsenkörper 20 ein Betätigungsabschnitt 27 ausgebildet, welcher das Drehen des Düsenkörpers 20 von Hand erleichtert.An actuating section 27 is formed on the nozzle body 20 on the inside of the tub, which facilitates the rotation of the nozzle body 20 by hand.

Bei der in Fig. 2 dargestellten Ausführungsform ist eine Führungshülse 17 entbehrlich, da der Düsenkörper 20 mit einem hinteren hülsenförmigen Abschnitt unmittelbar in dem Gehäuse 10 drehbar gelagert ist. Die Druckwasser- und Luftzufuhr ist etwas anders gestaltet als bei der Ausführungsform gemäß Fig. 1, die Funktionsweise, insbesondere auch hinsichtlich der Ausbildung eines Venturi-Effekts, ist jedoch der gleiche. Auch in Fig. 2 befindet sich der Düsenkörper 20 in seiner Abfließdrehstellung. Daraus ist zu erkennen, daß auch hier die Strahlaustrittsöffnung 24 tiefer als die Wassereintrittsöffnung 25 und letztere höher als die Druckwasserleitung 15 liegen, so daß in dem Düsenaustrittsbereich kein Restwasser stehen bleibt, wenn die Whirlpooleinrichtung außer Betrieb gesetzt ist.In the embodiment shown in FIG. 2, a guide sleeve 17 is dispensable since the nozzle body 20 is rotatably mounted directly in the housing 10 with a rear sleeve-shaped section. The supply of pressurized water and air is designed somewhat differently than in the embodiment according to FIG. 1, but the mode of operation, in particular also with regard to the formation of a venturi effect, is the same. 2, the nozzle body 20 is in its drain rotation position. From this it can be seen that the jet outlet opening 24 is also lower than the water inlet opening 25 and the latter higher than the pressurized water line 15, so that no residual water remains in the nozzle outlet area when the whirlpool device is put out of operation.
