Definitions

  • the invention is a further development of the hydromassage nozzle described in EP-B-209646.
  • Hydromassage jets are known in various configurations. They work on the principle of a water jet pump with or without the aid of a blower. They are used to generate an air bubble in water basins, so-called whirlpools.
  • Hydromassage jets are known which are provided for installation in the water basin side walls.
  • the assembly in the side wall has the disadvantage that the massage effect, which is usually caused by a water / air mixture, only hits the bathing guest lying in the bathtub to the side, while massage on the back is not possible. A comprehensive massage effect is not achieved. With such an arrangement, the body of the bathing guest is not exposed to a full massage. Splashing water occurs when such nozzles are installed in the area of the pool floor.
  • a further disadvantage of known hydromassage jets is that the irradiated medium (water and / or air) always has a specific jet direction, which may be adjustable, but only produces a small area-covering massage effect in a jet-like manner, in particular such known hydromassage jets cannot be closed.
  • Nozzles which serve the pure supply of compressed air.
  • the compressed air nozzles are distributed in a multiplicity of bores over the bottom surface and walls of the water basin, which naturally leads to sealing problems.
  • These nozzles like the first mentioned nozzles, cannot be closed, the nozzle mouths are not covered, bath water and soap residues can penetrate the supply system. This disadvantage leads to hygiene problems.
  • the hydromassage nozzle from which this invention is based also has disadvantages.
  • the distributor in the form of the jet deflection, deflection or deflection device placed in front of the nozzle housing in the jet direction generates a backflow in the direction of the air supply.
  • the backflow reduces the venturi effect or completely cuts off the air supply, so that sufficient amounts of air can only be mixed into the propellant jet if an additional compressed air generator is used.
  • the outlet opening (s) formed between the nozzle housing and the distributor cannot accommodate the increased volume flow of the mixture produced by the admixture of air and to be blasted into the tub.
  • the cross section of the outlet openings is enlarged, the jet pressure is disadvantageously reduced and the desired area coverage of the jet and the desired jet intensity for an effective massage are eliminated.
  • the channel walls of the various medium feeds are not shaped to be streamlined. Flow noise and high flow resistance form.
  • the water / air mixture is generated at a Venturi nozzle, which is connected upstream of the deflection of the jet in the desired direction of jet.
  • the known closure devices are also not aerodynamically shaped. They oppose the flowing medium with a high flow resistance, which disadvantageously leads to a water backflow which hinders or interrupts entry into the air supply line and the air supply. They are expansive in size and can only be accommodated in an axially movable manner in enlarged nozzle housings.

This is achieved through the characterizing features of the main claim and / or the independent ancillary claims.

  • both a multi-distributed water jet and a multi-distributed air jet can be blasted into the interior of the water basin. It is possible to use and select the known systems (water jet pump with injection air without or with blower, or only with blower) with only one nozzle housing. In the case of floor nozzles in particular, the jet of water and air that is generated is radiated into the interior of the water basin over a wide area, in a radial, ring-like, star-shaped or funnel-shaped manner, without splashing water in the vertical direction, which is why it can also be installed in basins with a shallow water depth, for example, foot basins .

Description

Bei der Erfindung handelt es sich um eine Weiterentwicklung der in der EP-B-209646, beschriebenen Hydromassagedüse.The invention is a further development of the hydromassage nozzle described in EP-B-209646.

Hydromassagedüsen sind in verschiedenen Ausgestaltungen bekannt. Sie arbeiten nach dem Prinzip der Wasserstrahlpumpe mit oder ohne Zuhilfenahme eines Gebläses. Sie werden eingesetzt zur Erzeugung eines Luftsprudels in Wasserbecken, sogenannten Whirlpools.Hydromassage jets are known in various configurations. They work on the principle of a water jet pump with or without the aid of a blower. They are used to generate an air bubble in water basins, so-called whirlpools.

Es sind Hydromassagedüsen bekannt, die zum Einbau in die Wasserbecken-Seitenwände vorgesehen sind. Die Montage in der Seitenwand hat den Nachteil, daß die in der Regel durch ein Wasser-Luftgegemisch hervorgerufene Massagewirkung den in der Badewanne liegenden Badegast nur seitlich trifft, während Massage am Rücken nicht möglich ist. Eine flächendeckende Massagewirkung wird nicht erreicht. Der Körper des Badegast wird bei einer solchen Anordnung einer Vollmassage nicht ausgesetzt. Bei Einbau solcher Düsen in den Bereich des Beckenbodens entsteht Spritzwasser.Hydromassage jets are known which are provided for installation in the water basin side walls. The assembly in the side wall has the disadvantage that the massage effect, which is usually caused by a water / air mixture, only hits the bathing guest lying in the bathtub to the side, while massage on the back is not possible. A comprehensive massage effect is not achieved. With such an arrangement, the body of the bathing guest is not exposed to a full massage. Splashing water occurs when such nozzles are installed in the area of the pool floor.

Ein weiterer Nachteil bekannter Hydromassagedüsen besteht darin, daß das eingestrahlte Medium (Wasser und/oder Luft) stets eine bestimmte Strahlrichtung besitzt, die zwar richtungsverstellbar sein kann, jedoch strahlartig nur geringe flächendeckende Massagewirkung erzeugt, insbesondere sind derartige bekannte Hydromassagedüsen nicht verschließbar.A further disadvantage of known hydromassage jets is that the irradiated medium (water and / or air) always has a specific jet direction, which may be adjustable, but only produces a small area-covering massage effect in a jet-like manner, in particular such known hydromassage jets cannot be closed.

Es sind Düsen bekannt, die der reinen Druckluftzufuhr dienen. Nachteiligerweise sind die Druckluftdüsen in einer Vielzahl von Bohrungen über die Bodenfläche und Wandungen des Wasserbekkens verteilt, was natürlich zu Abdichtproblemen führt. Diese Düsen, wie auch die erstgenannten Düsen, sind nicht verschließbar, die Düsenmündungen sind unverdeckt, es können Badewasser und Seifenreste in das Zuleitungssystem eindringen. Dieser Nachteil führt zu Hygieneproblemen.Nozzles are known which serve the pure supply of compressed air. Disadvantageously, the compressed air nozzles are distributed in a multiplicity of bores over the bottom surface and walls of the water basin, which naturally leads to sealing problems. These nozzles, like the first mentioned nozzles, cannot be closed, the nozzle mouths are not covered, bath water and soap residues can penetrate the supply system. This disadvantage leads to hygiene problems.

Weder die vorbeschriebenen Wasserdüsen, noch die letztgenannten Luftdüsen wirkend flächendeckend, die eingestrahlte Luftmenge wird rasch durch Auftrieb ausgetragen, je höher der Einstrahldruck, je nachteiliger und schneller erfolgt der Aufstieg der Luftblasen, die für die Massageintensität maßgebend sind.Neither the above-described water jets nor the last-mentioned air jets have a full-coverage effect, the amount of air blasted in is quickly discharged by buoyancy, the higher the jet pressure, the more disadvantageously and quickly the air bubbles rise, which are decisive for the massage intensity.

Auch die Hydromassagedüse von der diese Erfindung ausgeht besitzt Nachteile. Der dem Düsengehäuse in Ausstrahlrichtung vorgesetzte Verteiler in Form der Strahlauslenk, Umlenk-, oder Ablenkvorrichtung erzeugt in Richtung der Luftzuführung einen Rückstau. Der Rückstau vermindert die Venturiwirkung oder unterbricht die Luftzuführung total, sodaß nur bei Verwendung eines zusätzlichen Drucklufterzeugers ausreichende Luftmengen dem Treibstrahl beigegemischt werden können.The hydromassage nozzle from which this invention is based also has disadvantages. The distributor in the form of the jet deflection, deflection or deflection device placed in front of the nozzle housing in the jet direction generates a backflow in the direction of the air supply. The backflow reduces the venturi effect or completely cuts off the air supply, so that sufficient amounts of air can only be mixed into the propellant jet if an additional compressed air generator is used.

Die zwischen dem Düsengehäuse und dem Verteiler gebildete(n) Auslaßöffnung(en) kann-(können) den vergrößerten Volumenstrom des durch die Luftbeimischung erzeugten und in die Wanne einzustrahlenden Gemisches, nicht aufnehmen. Bei Vergrößerung des Querschnittes der Auslaßöffnungen reduziert sich nachteiligerweise der Einstrahldruck und die gewünschte Flächendeckung des Strahles und die gewünschte Strahlstärke für eine wirksame Massage entfällt.The outlet opening (s) formed between the nozzle housing and the distributor cannot accommodate the increased volume flow of the mixture produced by the admixture of air and to be blasted into the tub. When the cross section of the outlet openings is enlarged, the jet pressure is disadvantageously reduced and the desired area coverage of the jet and the desired jet intensity for an effective massage are eliminated.

Die Kanalwandungen der verschiedenen Mediumzuführungen sind nicht strömungsgünstig geformt. Es bilden sich Strömungsgeräusche und hoher Durchflußwiderstand. Nachteiligerweise erfolgt die Erzeugung des Wasser-/Luftgemisches an einer Venturidüse, die in Strömungsrichtung der Umlenkung des Strahles in die gewünschte Einstrahlrichtung vorgeschaltet ist.The channel walls of the various medium feeds are not shaped to be streamlined. Flow noise and high flow resistance form. Disadvantageously, the water / air mixture is generated at a Venturi nozzle, which is connected upstream of the deflection of the jet in the desired direction of jet.

Auch die bekannten Verschlußvorrichtungen sind nicht strömungsgünstig geformt. Sie setzten dem strömenden Medium einen hohen Durchflußwiderstand entgegen, der nachteiligerweise zu einem Wasserrückstau führt, der in die Luftzuleitung Eintritt und die Luftzufuhr behindert oder unterbricht. Sie sind ausladend groß und können nur in vergrößerten Düsengehäusen axial bewegbar aufgenommen werden.The known closure devices are also not aerodynamically shaped. They oppose the flowing medium with a high flow resistance, which disadvantageously leads to a water backflow which hinders or interrupts entry into the air supply line and the air supply. They are expansive in size and can only be accommodated in an axially movable manner in enlarged nozzle housings.

Dem Gegenstand der Erfindung kommt die Aufgabe zu, die Funktion und Wirkungsweise einer ansich bekannten Hydromassagedüse zu verbessern und die Nachteile bekannter Hydromassageddüsen zu beseitigen. Dies wird erreicht, durch die kennzeichnenen Merkmale des Hauptanspruches und/oder der unabhängigen Nebenansprüche.The object of the invention is to improve the function and mode of operation of a hydro massage nozzle known per se and to eliminate the disadvantages of known hydro massage nozzles. This is achieved through the characterizing features of the main claim and / or the independent ancillary claims.

Die Umlenkung des Treibstrahles, in die annähernd gewünschte Einstrahlrichtung, noch vor der Vermischung der Medien, hat den Vorteil, daß die Zuführung des Treibstrahles unter günstigen Strömungsbedingungen erfolgt, eine leistungschwächere Umlauf pumpe kann eingesetzt werden, die gewünschte Venturiwirkung wird begünstigt, Wasserrückstau in die Luftleitung wird vermieden, die Verwirbelung der Medien wird wesentlich verbessert, Strömungsgeräusche werden reduziert. Der Fangstrahl (Luft) wird in die bereits umgelenkte Strömungsrichtung ohne Strömungswiderstände eingesogen und beide Medien strömen in das Innenbecken ein, ohne daß enge Durchflußwiderstände zu überwinden sind und ohne daß Rückstau entsteht. Durch die Bewegbarkeit der Strahlablenkplatte ist die Richtung der Einstrahlung wählbar, dabei kann die Strahlablenkplatte mit bekannten Einstrahlöffnungen beliebiger Formgebung ausgestattet sein. (Einstrahlig, mehrstrahlig, rund, schlitzartig, ringartig, in radialer oder vertikaler Anordnung.)The deflection of the propulsion jet, in the approximately desired direction of irradiation, even before the media are mixed, has the advantage that the supply of the propulsion jet takes place under favorable flow conditions, a less powerful circulation pump can be used, the desired venturi effect is favored, water backflow into the air line is avoided, the turbulence of the media is significantly improved, flow noises are reduced. The trapping jet (air) is sucked in in the already deflected direction of flow without flow resistance and both media flow into the inner basin without having to overcome narrow flow resistance and without any back pressure. Due to the mobility of the beam deflection plate, the direction of the radiation can be selected; the beam deflection plate can be equipped with known radiation openings of any shape. (Single-beam, multi-beam, round, slot-like, ring-like, in a radial or vertical arrangement.)

Der Gegenstand der Erfindung ist nutzbar als Wand- oder Bodendüse. Dabei kann die Mediumeinstrahlung sowohl vertikal, wie auch radial abgelenkt durch entsprechende Einstrahlöffnungen erfolgen. Die Einstrahlung kann unter einem beliebigen Winkel zwischen 0-90 Grad zur Montageebene erfolgen. Das als Strahlablenkplatte bezeichnete Teil dient als Verteiler des einzustrahlenden Mediums, die Einstrahlöffnung(en) kann (können) über den gesamten Bereich von 90 Grad zu der Ebene auf der die Hydromassagedüse montiert ist angeordnet sein.The object of the invention can be used as a wall or floor nozzle. The medium radiation can be deflected both vertically and radially through appropriate radiation openings. The irradiation can take place at any angle between 0-90 degrees to the assembly level. The part referred to as the jet deflecting plate serves as a distributor of the medium to be blasted in, the jet opening (s) can be arranged over the entire area of 90 degrees to the plane on which the hydromassage nozzle is mounted.

Durch die erfindungsgemäße Düsenkonstruktion kann sowohl ein mehrfach verteilter Wasserstrahl, wie auch ein mehrfach verteilter Luftstrahl in das Innere des Wasserbeckens eingestrahlt werden. Dabei ist es möglich mit nur einem Düsengehäuse die bekannten Systeme (Wasserstrahlpumpe mit Injektionsluft ohne oder mit Gebläse, oder nur mit Gebläse) zu nutzen und zu wählen. Insbesondere bei Bodendüsen wird der erzeugte Strahl aus Wasser und Luft breitflächig, strahlenförmig, ringartig, sternförmig oder trichterförmig in das Innere des Wasserbeckens eingestrahlt, ohne daß in vertikaler Richtung Spritzwasser entsteht, deshalb ist auch der Einbau in Becken mit geringer Wassertiefe, beispielsweise Fußwaschbecken, möglich. Eingestrahlte Luft verläßt die Düse nicht sofort in Auftriebsrichtung, je höher der Einstrahldruck, umso länger benötigen die Luftblasen bis diese sich aus dem Wasserstrahl lösen und in die vertikale Auftriebsrichtung gelangen. Luftblasen, die mit einem Luft-Wassergemisch eingestrahlt werden gelangen durch die Vermischung mit dem Wasserstrahl naturgemäß recht weit in das Innere des Wasservolumens, bis sich diese aus dem Wasserstrahl lösen und zum Auftrieb gelangen. Der Wasser-Luftdurchsatz und damit verbunden die Massagewirkung wird deshalb wesentlich erhöht. Anstelle von 40-80 Einzelbohrungen im Bodenbereich des Wasserbekkens können 6-8 erfindungsgemäße Düsen die gesamte Fläche des Wasserbeckens mit einem Sprudel und mit leistungsfähiger Massage abdecken. Die Gefahr von Undichtigkeiten wird auf ein Minimum reduziert. Vorzugsweise paarweise und parallel im Boden eines Wasserbeckens eingelassen, bieten die erfindungsgemäßen Düsen dem Badegast eine breitflächig wirkende Unterwassermassage. Durch Drehen des Körpers kann sowohl Rücken-, Brust- wie auch Seitenpartie dem düsenbestückten Beckenboden zugewandt werden.Due to the nozzle construction according to the invention tion, both a multi-distributed water jet and a multi-distributed air jet can be blasted into the interior of the water basin. It is possible to use and select the known systems (water jet pump with injection air without or with blower, or only with blower) with only one nozzle housing. In the case of floor nozzles in particular, the jet of water and air that is generated is radiated into the interior of the water basin over a wide area, in a radial, ring-like, star-shaped or funnel-shaped manner, without splashing water in the vertical direction, which is why it can also be installed in basins with a shallow water depth, for example, foot basins . Blown-in air does not leave the nozzle immediately in the direction of buoyancy, the higher the jet pressure, the longer it takes the air bubbles to separate from the water jet and reach the vertical direction of buoyancy. Air bubbles that are blasted in with an air-water mixture naturally get quite far into the interior of the water volume when mixed with the water jet until they detach from the water jet and become buoyant. The water-air flow and the associated massage effect is therefore significantly increased. Instead of 40-80 individual holes in the bottom area of the water basin, 6-8 nozzles according to the invention can cover the entire surface of the water basin with a bubble and with a powerful massage. The risk of leaks is reduced to a minimum. The nozzles according to the invention preferably provide the bathing guest with a wide-area underwater massage, set in pairs and parallel in the bottom of a water basin. By turning the body, the back, chest and side areas can be turned towards the nozzle-equipped pelvic floor.

Durch die Aufteilung bilden sich vorteilhaft mehrere Venturidüsen wodurch die Vermischung der Medien begünstig wird. Die Luftzuführung kann unter Nutzung eines Gebläses verbessert werden. Vorteilhaft münden bei dieser Ausgestaltung die Medienzuführungen getrennt in das Innenbecken. Vorteilhaft erfolgt dabei die Einstrahlung mehrstrahlig und die Vermischung außerhalb des Düsengehäuses im Innenbecken.The embodiment according to variant 2c has the advantage that the driving jet is deflected in a flow-favorable manner and is divided into several partial jets. The division advantageously forms a plurality of Venturi nozzles, which facilitates the mixing of the media. The air supply can be improved using a fan. In this embodiment, the media feeds advantageously open separately into the inner basin. The irradiation is advantageously carried out in multiple beams and the mixing outside the nozzle housing in the inner basin.

Die Ausgestaltung gemäß der Variante 2d hat den Vorteil, daß die Rückschlagvorrichtung einerseits dem Verschluß der Düsenmündung-, und andererseits zur Umlenkung des Treibstrahles dient.

Advantageously, the non-return device with a conical or spherical surface can be pivoted in a known manner for beam deflection and can be inserted into a vertically arranged bore in the beam deflection plate.

Die Ausbildung des Verschlußkörpers als Tellerventil hat den Vorteil der besonders flachen Bauweise, die vorteilhaft einerseits dem Verschluß der Düsenmündung, und andererseits bedingt durch die tellerförmige Bauweise der Mediumumlenkung dient. Vorteilhaft kann durch die als Tellerventil ausgebildete bewegliche Strahlablenkplatte die Richtung der Mediumausstrahlung gewählt-, und in Pumpen-Stillstandszeiten die Düsenmündung geschlossen werden. Vorteilhaft läßt sich in das Tellerventil mit vertikaler Bohrung als Einstrahlöffnung, eine ansich bekannte und ververschwenkbare Kugeldüse einsetzen.

The design of the closure body as a poppet valve has the advantage of the particularly flat design, which advantageously serves on the one hand to close the nozzle mouth and, on the other hand, due to the plate-shaped design, serves to deflect the medium. The direction of the medium radiation can advantageously be selected by the movable jet deflection plate designed as a poppet valve, and the nozzle mouth can be closed during pump downtimes. A well-known and pivotable ball nozzle can advantageously be used in the poppet valve with a vertical bore as the jet opening.

Weitere vorteilhafte Ausgestaltungen sind der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispieles, den Zeichnungen und den Ansprüchen entnehmbar.

Fig. 1 Bei der im vertikalen Schnitt gezeigten erfindungsgemässen Düsenkonstruktion, ist der Mediumaustrittsöffnung B eine Strahlablenkplatte 1 vorgesetzt. Die Strahlablenkplatte 1 kann vorzugsweise ein Tellerventil sein, die(das) an der Umfanglinie 2 an dem Düsengehäuse 3 Abdichtung erreicht. Dem Zwecke der Abdichtung kann ein Gummiring 4 dienen, der seinen Sitz sowohl im Gehäuse 3, wie auch in der Strahlablenkplatte 1 haben kann. Das Gehäuse 3 ist vorzugsweise durch ein Gewinde 5 an dem Boden oder der Wandung 6 des Wasserbeckens festgespannt und zeigt auf der Seite A in wenigstens eine Medium-Zufuhrleitung 8 über die Wasser oder Luft zuführbar ist. Das unter Druck zugeführte Medium hebt die Strahlablenkplatte 1 aus ihrem Sitz und tritt durch wenigstens eine Einstrahlöffnung 9 vorzugsweise jedoch durch eine Vielzahl von Einstrahlöffnungen in das Innere des Wasserbeckens 7 ein. Bevorzugt erfolgt die Einstrahlung parallel zur Montageebene C-D durch Einstrahlöffnungen, die radial, tangential oder in beliebigem Winkel zwischen 0-90 Grad zur Montageebene angeordnet sind, die Einstrahlung kann ringartig erfolgen, sie kann schlitzartig oder durch runde Öffnungen erfolgen, die Einstrahlöffnungen können beliebige Formen besitzen. Unabhängig von dem ersten Medium, das gasförmig sein kann, kann der Düsenkonstruktion durch die Öffnung 10 ein zweites Medium, beispielsweise Wasser, zugeführt werden, das vorzugsweise ebenfalls durch die Einstrahlöffnung 9 in das Innenbecken 7 eingestrahlt wird. Auch getrennte Einstrahlöffnungen für die verschiedenen Medien sind denkbar. Bei Zuführung von zwei verschiedenen Medien kann eines als Treibstrahl genutzt werden, wobei das andere Medium im Prinzip der Wasserstrahlpumpe mitgerissen wird. Das Prinzip der Wasserstrahlpumpe ist bekannt und braucht nicht näher erläutert zu werden. Der Treibstrahl kann sowohl über die Zuführung 8 wie auch über die Zuführung 10 geführt werden, wesentlich ist die Umlenkung des Treibstrahles aus der Zuführung A in eine oder mehrere Richtungen parallel zur Montageebene C-D oder einem beliebigen Winkel dazu.Fig. 1 In the nozzle construction according to the invention shown in vertical section, a jet deflection plate 1 is placed in front of the medium outlet opening B. The jet deflector plate 1 may preferably be a poppet valve that seals at the peripheral line 2 on the nozzle housing 3. A rubber ring 4 can serve the purpose of sealing, which can have its seat both in the housing 3 and in the beam deflection plate 1. The housing 3 is preferably clamped by a thread 5 to the bottom or the wall 6 of the water basin and shows on the side A in at least one medium supply line 8 via which water or air can be supplied. The medium supplied under pressure lifts the beam deflection plate 1 out of its seat and enters the interior of the water basin 7 through at least one radiation opening 9, but preferably through a plurality of radiation openings. The radiation is preferably parallel to the mounting plane CD through radiation openings which are arranged radially, tangentially or at any angle between 0-90 degrees to the mounting plane, the radiation can be ring-like, it can be slot-like or through round openings, the radiation openings can have any shape . Regardless of the first medium, which can be gaseous, a second medium, for example water, can be supplied to the nozzle construction through the opening 10, which is preferably also irradiated into the inner basin 7 through the radiation opening 9. Separate radiation openings for the different media are also conceivable. When two different media are supplied, one can be used as a propulsion jet, the other medium being entrained in principle by the water jet pump. The principle of the water jet pump is known and need not be explained in more detail. The driving jet can be guided both via the feeder 8 and the feeder 10; the deflection of the driving jet from the feeder A in one or more directions parallel to the assembly plane C-D or at any angle is essential.

Die Umlenkung des Treibstrahles kann erfolgen, durch eine konische Ausbildung 11 des Endes der Zuführung 8 wie in dem Detail Fig. 2 gezeigt oder durch eine kegelige Ausbildung 13 der Strahlablenkplatte 1 wie im Detail in Fig. 3 veranschaulicht.The deflection of the driving jet can take place by a conical configuration 11 of the end of the feed 8 as shown in detail in FIG. 2 or by a conical configuration 13 of the beam deflecting plate 1 as illustrated in detail in FIG. 3.

Neben der vorausgehend beschriebenen Möglichkeit, bei welcher ein Wasser-Luftgemisch durch die bekannte Bernoulliwirkung erzeugt und in das Innere des Wasserbeckens eingestrahlt wird, besteht natürlich auch die Möglichkeit Wasser und Druckluft der Düsenkombination zuzuführen, wodurch natürlich wesentlich größere Luftmengen eingestrahlt werden, als dies beim Prinzip der Wasserstrahlpumpe der Fall ist. Somit sind drei verschiedene Funktionsmöglichkeiten dadurch gegeben, daß einmal nur Druckluft dem Inneren des Wasserbeckens zugeführt wird, (Betrieb mit Gebläse) im weiteren kann Wasser mit oder ohne Injektionsluft zugeführt werden (Betrieb mit Umlaufpumpe) letztlich kann zugeführt werden, Wasser mit Injektions- und Druckluft (Betrieb mit Umlaufpumpe und Gebläse). Dabei kann die Injektionsluft oder Druckluft regulierbar sein. Zur Erzeugung des Gemisches kann sowohl die Bernoulli- wie die Venturiwirkung genutzt werden.In addition to the previously described option, in which a water-air mixture is generated by the well-known Bernoulli effect and blasted into the interior of the water basin, there is of course also the possibility of supplying water and compressed air to the nozzle combination, which of course causes much larger amounts of air to be blasted in than is the case with the principle the water jet pump is the case. So there are three different functions given that only compressed air is supplied to the inside of the water basin, (operation with blower), water can also be supplied with or without injection air (operation with circulation pump) ultimately water can be supplied with injection and compressed air (operation with circulation pump and Fan). The injection air or compressed air can be regulated. Both the Bernoulli and Venturi effects can be used to generate the mixture.

Die Strahlablenkplatte 1 kann starr gelagert sein und in das Düsengehäuse 3 kann beispielsweise eine Rückschlagkugel oder -klappe oder eine sonstige rückflußverhindernde Vorrichtung eingebaut sein, die das Eindringen von Badewasser in das Zuleitungssystem verhindert. Die Strahlablenkplatte 1 ist vorzugsweise durch die Vorrichtung 12 die ein Ring sein kann, an dem Anschlag des Düsengehäuses 3 gehalten, auch eine einschraubbare Halterung ist denkbar.The jet deflection plate 1 can be rigidly mounted and, for example, a non-return ball or flap or other non-return device can be installed in the nozzle housing 3, which prevents the penetration of bathing water into the supply system. The jet deflection plate 1 is preferably held by the device 12, which can be a ring, on the stop of the nozzle housing 3, and a screw-in holder is also conceivable.

Besonders vorteilhaft ist es, die Einlaßdüse(n) 9 radialtangential anzuordnen und den Einstrahldruck zur Rotationsbewegung der Strahlablenkplatte und zur Verwirbelung des oder der Medienmischung zu nutzen.It is particularly advantageous to arrange the inlet nozzle (s) 9 radially tangentially and to use the jet pressure for the rotational movement of the jet deflecting plate and for swirling the media mixture or media.

Bie besonders hohem Druck des Treibstrahles erfolgt die Vermischung der Medien außerhalb der Einstrahlöffnung(en) in Richtung zum Wasserbeckeninneren hin. Die Zuführung 8 kann mit einer Rückschlagvorrichtung versehen sein, deren gekrümmte Oberfläche beispielsweise kegelförmig oder kugelförmig ist und der Strahlablenkung dient. Dieses Beispiel veranschaulicht sich insbesondere in Fig. 3. Der dort gezeigte Kegel 13 kann beweglich sein und dem Verschluß der Zuführung 8 sowie nach Öffnung durch den anstehenden Druck des Mediums, der Strahlablenkung dienen.At a particularly high pressure of the propulsion jet, the media are mixed outside the jet opening (s) towards the inside of the pool. The feed 8 can be provided with a non-return device, the curved surface of which is, for example, conical or spherical and serves to deflect the beam. This example is illustrated in particular in FIG. 3. The cone 13 shown there can be movable and serve to close the feed 8 and, after opening due to the pressure of the medium, the beam deflection.

Fig. 4 zeigt eine weitere bevorzugte Ausführungsart für die Strahlablenkung. Die Zuführung 8 teilt sich an ihrem oberen Ende in mehrere rohrartige Ausläße 9a. Der Treibstrahl kann dabei über die Ausläße 9a geführt werden oder er kann über die Öffnungen 10a dem Inneren 7 des Wasserbekkens zugeführt werden. Vorzugsweise ist auch diese Variante durch einen Deckel, der starr, beweglich oder als Tellerventil ausgebildet sein kann, abgedeckt.Fig. 4 shows a further preferred embodiment for the beam deflection. The feeder 8 divides at its upper end into several tubular outlets 9a. The propellant jet can be guided through the outlets 9a or it can be supplied to the interior 7 of the water tank via the openings 10a. This variant is preferably also covered by a cover which can be rigid, movable or designed as a poppet valve.

Die Strahlablenkplatte 1 oder das Tellerventil kann natürlich auch mit wenigstens einer vertikal wirkenden Bohrung zum Auslaß für wenigstens eines der Medien ausgerüstet sein. Der Verteilerstern kann ebenfalls vertikal wirkende Ausläße 14 tragen. Auch bei der in Fig. 4 gezeigten Variante können die Ausläße 9a in jedem beliebigen Winkel zwischen 0-90 Grad gegenüber der Montageebene C-D angeordnet sein. Selbstverständlich ist es bei allen Varianten (Fig. 1-4) möglich, die Strahlablenkplatte 1 bzw. das Tellerventil 1 mit Bohrungen zu versehen, aus welchen strahlenartig eines der Medien oder beide Medien oder ein Gemisch beider Medien ausgestrahlt werden.The jet deflector plate 1 or the poppet valve can of course also be equipped with at least one vertically acting bore for the outlet for at least one of the media. The distributor star can also carry vertically acting outlets 14. In the variant shown in FIG. 4, the outlets 9a can be arranged at any angle between 0-90 degrees with respect to the assembly plane C-D. Of course, in all variants (FIGS. 1-4) it is possible to provide the beam deflection plate 1 or the poppet valve 1 with bores from which one of the media or both media or a mixture of both media are radiated.

Fig. 5 zeigt die Zuführung 8 mit einer erfindungsgemäßen Einschnürung 20 am oberen Düsenhals. Erfindungsgemäß wird vorgeschlagen, die Einschnürung als Vertiefung in die Zuleitung 8 einzuarbeiten und ringartig auszubilden. Weiter wird vorgeschlagen, die Einschnürung 20 mit Öffnungen 21 zu versehen, die einen Übergang in das innere der Zuführung 8 schaffen.FIG. 5 shows the feed 8 with a constriction 20 according to the invention on the upper nozzle neck. According to the invention, it is proposed to incorporate the constriction as a depression in the feed line 8 and to form it in a ring-like manner. It is also proposed to provide the constriction 20 with openings 21 which create a transition into the interior of the feed 8.

Erfindungsgemäß wird vorgeschlagen, die Strahlablenkplatte 1 mit einem Schraubgewinde zu versehen, der eine Höhenverstellung ermöglicht, sodaß je nach Bedienung sich der Querschnitt der Auslaßöffnung 9 öffnet oder verschließt.According to the invention, it is proposed to provide the beam deflection plate 1 with a screw thread, which enables height adjustment, so that the cross section of the outlet opening 9 opens or closes depending on the operator.

In einer vorteilhaften Ausgestaltung wird vorgeschlagen, den Hals der Zuleitung 8 derart am oberen Ende 22 zu formen, daß sich ein Ausstrahlwinkel "a" zwischen 0 bis 70 Grad ergibt. Die Zuführung 8 kann obenseitig geöffnet oder geschlossen sein, die Strahlablenklpatte 1 kann als Deckel für die Zuführung 8 und der Strahlausformung dienen.In an advantageous embodiment, it is proposed to shape the neck of the feed line 8 at the upper end 22 in such a way that an emission angle "a" between 0 and 70 degrees results. The feed 8 can be open or closed on the top, the beam deflecting plate 1 can serve as a cover for the feed 8 and the beam shaping.

Die erfindungsgemäße Strahlumlenkeinrichtung kann selbstverständlich auch derart gestaltet sein, daß die Umlenkung der Einstrahlmedien, lediglich durch eine abgewinkelte Strahlablenkplatte umgelenkt wird.The beam deflection device according to the invention can of course also be designed in such a way that the deflection of the radiation media is deflected only by an angled beam deflection plate.

Fig. 6 zeigt eine derartige erfindungsgemäße Vorrichtung. Derartige Ablenkplatten können vorzugsweise auch an Düsen bekannter Art angebracht werden, welche in die Seitenwandungen der Wasserbecken eingebaut sind. Dabei kann die Einstrahlung zum Wannenboden hin abgelenkt und breit unter den Körper des Badegastes verteilt werden. Erfindungsgemäß wird vorgeschlagen, derartige Abdeckplatten 50 so der Ausstrahlung vorzusetzen, daß die Ausstrahlung wahlweise in gerader Richtung A-B oder in abgelenkter Ausstrahlrichtung A-C erfolgt. Es wird vorgeschlagen, die Strahlablenkplatte verstellbar zu gestalten, sodaß diese den Strahl entweder ablenkt oder ungehindert austreten lässt. Gelöst wird diese Aufgabe beispielsweise durch eine vorklappbare Strahlablenkplatte. Auch mehrere Einzel-Auslaßöffnungen sind denkbar, die nach Wunsch geöffnet oder geschlossen werden.6 shows such a device according to the invention. Baffles of this type can preferably also be attached to nozzles of a known type which are built into the side walls of the water basin. The radiation can be deflected towards the bottom of the bath and spread widely under the body of the bathing guest. According to the invention, it is proposed that such cover plates 50 be placed in front of the radiation in such a way that the radiation takes place either in a straight direction A-B or in a deflected radiation direction A-C. It is proposed to make the beam deflection plate adjustable so that it either deflects the beam or allows it to emerge unhindered. This task is solved, for example, by a collapsible beam deflector. Several individual outlet openings are also conceivable, which can be opened or closed as desired.

Zur Vermeidung von Wassereintritt in das Düsengehäuse wird weiter vorgeschlagen, wenigstens eine trompentenartige Mündung der Zuleitung 8 aus einem elastischen Material anzufertigen, das sich in Pumpen-Stillstandszeiten wie eine Mündung an die Wandung des Gehäuses 3 anlegt. Bei eingeschaltetem Druckerzeuger wird das elastische Material in die gewünschte Ausstrahlposition gedrückt und die Düsenmündung freigegeben. Selbstverständlich ist es auch denkbar, die Strahlablenkplatte 1 oder bestimmte Teilbereiche der Ablenkplatte aus einem elastischen Material herzustellen, das bei ausgeschaltetem Druckerzeuger dem Zwecke des Verschlußes der Düsenmündung dient.In order to avoid water entering the nozzle housing, it is further proposed to make at least one trumpet-like mouth of the feed line 8 from an elastic material, which rests on the wall of the housing 3 like a mouth during pump downtimes. When the pressure generator is switched on, the elastic material is pressed into the desired ejection position and the nozzle mouth is released. Of course, it is also conceivable to manufacture the jet deflection plate 1 or certain partial areas of the deflection plate from an elastic material which serves the purpose of closing the nozzle mouth when the pressure generator is switched off.

Fig. 8 Das Düsengehäuse 3 ist mit einem flanschartigen Kragen 52 und einem Gewinde 5 an der Beckenumfassungswand 6 festgespannt. Vorzugsweise mündet das Gewinde 5 wasserbeckenrückseitig in einem Mehrfach-Hauptzuleitungsanschluß 82 über den die verschiedenen Medien zugeführt werden. Das Düsengehäuse 3 trägt im Zentrum eine Bohrung, die als Treibstrahlzuführung 8 ausgebildet ist. Sie trägt einerseits einen Anschlußschaft 53 der bevorzugt über ein Schraubgewinde in die Hauptzuleitung 51 mündet und andererseits eine Begrenzungswand 54 die mehrere Bohrungen 9aträgt und in ihrerVerlängerung zum Innenbecken 7 hin die Strahlablenkplatte 1 bildet oder aufnimmt und einerseits zum Innenbecken hin die Bohrungen 9a verdeckt und unterhalb der Strahlablenkplatte 1 vorzugsweise durch eine konische Ausformung 11 den Strahl verteilt und zu dem Umfang der Strahlablenkplatte zum Innenbecken hin, annähernd parallel zum Wasserbeckenboden einlenkt und innerhalb des beschriebenen Winkels einstrahlt.Fig. 8 The nozzle housing 3 is clamped to the pool surrounding wall 6 with a flange-like collar 52 and a thread 5. The thread 5 preferably opens at the rear of the water basin into a multiple main feed connection 82 via which the various media are fed. The nozzle housing 3 has a bore in the center, which is designed as a jet jet supply 8. It carries on the one hand a connecting shaft 53 which preferably opens into the main feed line 51 via a screw thread and on the other hand a boundary wall 54 which carries several bores 9a and forms or receives the beam deflection plate 1 in its extension towards the inner pool 7 and on the one hand hides the bores 9a towards the inner pool and below that Jet deflecting plate 1 preferably distributes the jet through a conical shape 11 and deflects it toward the circumference of the jet deflecting plate toward the inner pool, approximately parallel to the bottom of the water pool, and irradiates it within the angle described.

Koaxial zu den Bohrungen 9a ist wenigstens eine weitere Öffnung 10 vorzugsweise in Form einer oder mehrerer Bohrungen angelegt, die in die Hauptzuleitung 33 für das zweite Medium führt. Auch mehrere Bohrungen 10 können in die Hauptzuleitung 33 münden. Vorzugsweise trägt das Düsengehäuse 3 eine weitere Öffnung 55 die in die Hauptzuleitung 58, 30, 34 für ein weiteres Medium mündet, bevorzugt wird über diese Öffnung 55 Druckluft zugeführt und über die Öffnung 10 Saugluft geführt. Die Zuführung 8 trägt vorzugsweise eine Rückschlagsicherung 59 die das Eindringen von Badewasser in die Hauptzuleitung 51 verhindert. Als Rückflußsicherung kann auch eine Kugel dienen, auch eine federbelastete Rückflußsicherung ist denkbar oder eine Lippendichtung oder Klappenvorrichtung kann gewählt werden, welche erst dann öffnet, wenn Druck auf die Rückflußsicherung ausgewirkt wird und der beschleunigte Treibstrahl in Richtung zur Düsenmündung 9 hin die Rückflußsicherung öffnet. Derartige Rückflußsicherungen sind vielseitig bekannt, eine konstruktive Beschreibung ist daher nicht erforderlich.At least one further opening 10, preferably in the form of one or more bores, is made coaxially with the bores 9a and leads into the main feed line 33 for the second medium. A plurality of bores 10 can also open into the main feed line 33. The nozzle housing 3 preferably carries a further opening 55 which opens into the main feed line 58, 30, 34 for a further medium, preferably compressed air is supplied via this opening 55 and suction air is conducted via the opening 10. The feed 8 preferably carries a non-return device 59 which prevents bath water from entering the main feed line 51. A ball can also serve as a backflow preventer, a spring-loaded backflow preventer is also conceivable, or a lip seal or flap device can be selected, which only opens when pressure is exerted on the backflow preventer and the accelerated propellant jet opens the backflow preventer towards the nozzle mouth 9. Such backflow safeguards are widely known, a design description is therefore not necessary.

Bevorzugt liegt(liegen) die Öffnung(en) 10 in einer Ringnut 60 die als Vertiefung ausgebildet ist. Vorzugsweise trägt auch die Rückseite des Düsengehäuses 3 eine Nut 61 als Vertiefung für die Offnungsansätze. Auf dem bekannten Weg zur Einstrahlöffnung 9 hin nimmt der Treibstrahl nach dem Prinzip der Wasserstrahlpumpe den als Fangstrahl bekannten Anteil des zweiten Mediums mit, wobei sich ein Wasser-Luftgemisch bildet. Die Einstrahlung zum Innenbecken 7 hin erfolgt an der Umfanglinie der Strahlablenkplatte 1, 50. Bevorzugt wird über einen eigenen Druckerzeuger 26 Druckluft zugeführt. Die Zuführung von Druckluft kann erfolgen, ohne Benutzung einer Umlaufpumpe. Es ist jedoch auch möglich, eine Umlaufpumpe zur Erzeugung eines Treibstrahles und zusätzlich einen Druckerzeuger zur Erzeugung von Druckluft zu nutzen. Vorzugsweise tragen die Öffnungen 10, 55 ebenfalls Rückschlagsicherungen 86 der vorausgehend beschriebenen Art. Auch eine gemeinsame Rückflußsicherung 4 ist denkbar, die vorzugsweise in der Nähe der Einstrahlöffnung ihren Sitz erhält und die alle vorhandenen Öffnungen überdeckt und nur öffnet, wenn entsprechender Gegendruck ansteht.The opening (s) 10 preferably lie in an annular groove 60 which is designed as a depression. The rear of the nozzle housing 3 preferably also has a groove 61 as a depression for the opening approaches. In the known way to the jet opening 9, the propellant jet takes along with it the portion of the second medium known as the catch jet, whereby a water-air mixture is formed. The irradiation towards the inner pool 7 takes place on the circumferential line of the beam deflection plate 1, 50. Compressed air is preferably supplied via a separate pressure generator 26. Compressed air can be supplied without using a circulation pump. However, it is also possible to use a circulation pump to generate a propulsion jet and additionally a pressure generator to generate compressed air. The openings 10, 55 preferably also carry non-return devices 86 of the type described above. A common non-return valve 4 is also conceivable, which is preferably located in the vicinity of the irradiation opening and which covers all the existing openings and only opens when there is appropriate counterpressure.

Fig. 9 zeigt eine Ausführungsvariante, bei welcher die Strahlablenkplatte 1 beweglich gelagert ist. Vorzugsweise trägt die Zuführung 8 an ihrem oberen Ende einen Absatz 12 der als Halte lager für die Strahlablenkplatte 1 dient. Das in die Zuführung 8 hineinzeigende Teil trägt das Gegenlager 62 das vorzugsweise aus einem Sicherungsring besteht. Besonders vorteilhaft ist die Ausgestaltung, wenn die Öffnung(en) 55 koaxial zur Mittelachse der Zuführung 8 derart angeordnet sind daß diese nur in angehobenem Zustand der Strahlablenkplatte 1 von dem Treibstrahl durchströmt werden und diese bei niedergehaltenem Zustand durch einen Verschluß, vorzugsweise in Form eines Absatzes 63, verdeckt werden. Natürlich ist es auch denkbar, bei niedergehaltenem Zustand der Strahlablenkplatte 1 einen Ventilsitz derart zu bewegen, daß der Zufluß des Treibstrahles aus der Zuführung 8 unterbrochen wird. Dies ist beispielsweise erreicht, wenn durch die Rückseite der beweglichen Strahlablenkplatte 1 eine Abdichtvorrichtung gegen einen Dichtsitz geführt wird, der die Zuführung 8 schließt. Sobald der Pumpendruck abgeschaltet ist schließt der Ventilsitz, der beispielsweise ein O-Ring oder eine Lippendichtung, ein Zylinder- oder Stopfenventil sein kann, der von der Strahlablenkplatte 1 her niedergedrückt wird. Dabei kann auch die Schließkraft einer Feder zuhilfe genommen werden, auch das Eigengewicht der Strahlablenkplatte unterstützt den Ventil-Schließvorgang.FIG. 9 shows an embodiment variant in which the beam deflection plate 1 is movably mounted. Preferably, the feed 8 carries at its upper end a shoulder 12 which serves as a holding bearing for the beam deflector plate 1. The part pointing into the feed 8 carries the counter bearing 62, which preferably consists of a locking ring. The configuration is particularly advantageous if the opening (s) 55 are arranged coaxially to the central axis of the feed 8 in such a way that the driving jet flows through the beam deflecting plate 1 only in the raised state and through a closure, preferably in the form of a shoulder, when the beam is held down 63, are covered. Of course, it is also conceivable to move a valve seat in such a way that the beam deflecting plate 1 is held down in such a way that the inflow of the driving jet from the feed 8 is interrupted. This is achieved, for example, when a sealing device is guided through the back of the movable beam deflection plate 1 against a sealing seat, which closes the feed 8. As soon as the pump pressure is switched off, the valve seat closes, which can be, for example, an O-ring or a lip seal, a cylinder or plug valve, which is pressed down by the jet deflection plate 1. The closing force of a spring can also be used, the weight of the beam deflection plate also supports the valve closing process.

Fig. 10 zeigt eine erfindungsgemäße HydroMassagedüse, bei welcher der Düsenkörper 64 mit Treibstrahl-Druckluft- und Saugluft-Zuführung in ein Düsengehäuse 3 der bekannten Art eingesetzt ist. Der Düsenkörper 64 wird durch einen Schraubring 65 (linke Seite der Darstellung) oder durch einen Flanschring 66 (rechte Seite der Darstellung) in dem Düsengehäuse 3 gehalten. Erfindungsgemäß wird vorgeschlagen, den Düsenkörper 64 über ein Gewinde 72 einzuschrauben oder durch den Schraubring 65 oder Flanschring 66 festzuklemmen. Der Flanschring 66 kann zusätzlich als Deckplatte, vorzugsweise mit vergüteter Oberfläche, für den Flansch 52 des Düsengehäuses 3 dienen. Er kann durch ein auf seiner Innenseite liegendes Gewinde 67 oder durch ein an seinem äußeren Umfang liegendes Gewinde 68 an den Düsengehäuse 3 festgespannt sein. Auch eine Befestigung durch Halteschrauben 87 ist möglich. In einer bevorzugten Ausführungsvariante trägt der Flanschring 66 Öffnungen, die symmetrisch und deckungsgleich mit den Öffnungen 10, 10a, 55 des Düsenkörpers angeordnet sind. Durch Drehbewegung des Flanschringes werden die Öffnungen gegeneinander verschoben, bzw. geöffnet oder verschlossen. Dazu braucht der Flanschring nur drehbar gelagert zu sein. Der Drehbereich kann rundumlaufend sein, es kann aber auch ein kleiner Drehbereich genutzt werden (rechts, links). Der in das Düsengehäuse 3 eingesetzte Düsenkörper 64 stellt über die Zuführung 8 mit ihrer Verlängerung 53 eine Verbindung zu der Treibstrahl-Hauptzuführung 51 her. Die Öffnungen 10, 10a, 55 bewirken eine Verbindung zu der/den Hauptzuleitungen 30, 33, 34, 58 für Druck- und/ oder Saugluft, dabei kann als Verbindung zwischen den jeweiligen Hauptzuleitungen eine einfache Wanddurchbrechung 74, 75 in Form, beispielsweise einer Bohrung, dienen. Bei Trennung zwischen zwei verschiedenen Luft-Hauptzuleitungen 58 für Druckluft und 34 für Saugluft zu den Öffnungen 10, 10a und 55 kann beispielsweise eine Verlängerung dienen, die den Raum zwischen dem Ende einer Öffnung 10, 10a, 55 bis zum Wanddurchbruch in der Hauptzuleitung 34, 58 überbrückt. Auf diese bevorzugte Art gelangt eine bestimmte Luftart (Druckoder Saugluft) unmittelbar aus der jeweiligen Hauptzuleitung 34, 58 durch besagte Verlängerung zu der entsprechenden Öffnung 10, 10a, 55.10 shows a hydro-massage nozzle according to the invention, in which the nozzle body 64 with the supply of compressed air and suction air is inserted into a nozzle housing 3 of the known type. The nozzle body 64 is held in the nozzle housing 3 by a screw ring 65 (left side of the illustration) or by a flange ring 66 (right side of the illustration). According to the invention, it is proposed to screw in the nozzle body 64 via a thread 72 or to clamp it tightly with the screw ring 65 or flange ring 66. The flange ring 66 can additionally serve as a cover plate, preferably with a tempered surface, for the flange 52 of the nozzle housing 3. It can be clamped to the nozzle housing 3 by a thread 67 on its inside or by a thread 68 on its outer circumference. Attachment by means of retaining screws 87 is also possible. In a preferred embodiment variant, the flange ring 66 has openings which are arranged symmetrically and congruently with the openings 10, 10a, 55 of the nozzle body. By rotating the flange ring, the openings are shifted towards each other, or opened or closed. To do this, the flange ring only needs to be rotatably mounted. The rotation range can be all-round, but a small rotation range can also be used (right, left). The nozzle body 64 inserted into the nozzle housing 3 establishes a connection to the main jet feed line 51 via the feed 8 with its extension 53. The openings 10, 10a, 55 create a connection to the / the Main supply lines 30, 33, 34, 58 for compressed and / or suction air, a simple wall opening 74, 75 in the form of, for example, a bore, can serve as a connection between the respective main supply lines. When two different main air supply lines 58 for compressed air and 34 for suction air are separated to the openings 10, 10a and 55, an extension can be used, for example, which extends the space between the end of an opening 10, 10a, 55 to the wall opening in the main supply line 34, 58 bridges. In this preferred manner, a certain type of air (compressed or suction air) arrives directly from the respective main supply line 34, 58 through said extension to the corresponding opening 10, 10a, 55.

Erfindungsgemäß wird vorgeschlagen, die Strahlablenkplatte 1 zusammen mit dem Düsenkörper 64 drehbar in dem Düsengehäuse 3 zu lagern und den Öffnungen 10, 10a gegebenenfalls 55 auf ihrer der Beckeninnenseite 7 abgewandten Seite einen Vorsprung 70, beispielsweise in Form einer Nase oder eines Absatzes zuzuordnen, der je nach Drehstellung den Zugang zu wenigstens einer Öffnung versperrt. Eine solche Sperre kann natürlich auch zwischen dem Düsenkörper 64 und dem Mehrfachgehäuse 82 bzw. Gehäusekammer 71 angeordnet sein.According to the invention, it is proposed that the jet deflection plate 1, together with the nozzle body 64, be rotatably mounted in the nozzle housing 3 and that the openings 10, 10a, if necessary 55, be assigned a projection 70, for example in the form of a nose or a shoulder, on their side facing away from the inside of the pool 7 blocked access to at least one opening after rotation. Such a lock can of course also be arranged between the nozzle body 64 and the multiple housing 82 or housing chamber 71.
