Another disadvantage is that the installation takes place outside the sanitary unit and existing units cannot be retrofitted at all or only with difficulty. Repairs are also difficult or impossible.
  • whirl pools also have a suction device, for example via a fixedly mounted suction pipe.

Description

Die Erfindung betrifft eine Einrichtung nach dem Oberbegriff des Hauptanspruchs sowie einen zugehörigen Badeapparat.The invention relates to a device according to the preamble of the main claim and an associated bathing apparatus.

Der Begriff "sanitärer Apparat" umfaßt erfindungsgemäß solche sanitären Apparate, die Wasser aufnehmen, wie Badewannen, Schwimmbecken, Duschtassen etc.. Soweit im Zusammenhang mit einem sanitären Apparat nachstehend von einer Badewanne gesprochen wird, erfolgt dies lediglich beispielhaft.According to the invention, the term “sanitary apparatus” encompasses those sanitary apparatuses which absorb water, such as bathtubs, swimming pools, shower trays, etc. As far as in connection with a sanitary apparatus below a bathtub is spoken, this is only an example.

Seit langem sind Badewannen bekannt, die als sogenannte "Whirl-Pools" ausgebildet sind. Dabei wird in die gefüllte Badewanne Luft und/oder Wasser über eine oder mehrere Pumpen einzeln oder in Mischung unter Druck zugeführt. Die Zuführung erfolgt in der Regel über kleine Düsen, so daß die Luft und/oder das Wasser in Form feiner Strahlen eingedüst werden. Derartige Whirl-Pools dienen vor allem Massagezwecken, aber auch weiteren medizinischen Anwendungen.Bathtubs that have been designed as so-called "whirl pools" have long been known. Air and / or water is fed into the filled bathtub individually or as a mixture under pressure via one or more pumps. The supply is usually via small nozzles, so that the air and / or water are injected in the form of fine jets. Such whirl pools are used primarily for massage purposes, but also for other medical applications.

Bekannte Whirl-Pools weisen dazu im Boden beziehungsweise der Wand eine Vielzahl kleiner Öffnungen auf. Dies können entweder einfache Bohrungen sein oder aber Düsen, die in den Bohrungen befestigt sind und zum Teil eine Verstellbarkeit der Strömungsrichtung ermöglichen.Known whirl pools have a large number of small openings in the floor or wall. These can either be simple bores or nozzles that are fastened in the bores and in some cases allow the flow direction to be adjustable.

Ein großes Problem stellt dabei das Installationssystem dar. Da die Öffnung/Düsen in mehr oder weniger großem Abstand zueinander verlaufen, wird im Stand der Technik bisher jede an eine eigene Wasser-/Luft-Zuführung angeschlossen. Der Installationsaufwand ist entsprechend der Zahl der Düsen (zum Beispiel 50 bis 100) sehr groß. Ein weiterer Nachteil besteht darin, daß die Installation außerhalb des sanitären Aggregats erfolgt und vorhandene Aggregate gar nicht oder nur schwer nachrüstbar sind. Auch Reparaturen sind schwierig oder unmöglich.The installation system represents a major problem. Since the opening / nozzles run at a greater or lesser distance from one another, each of the prior art has so far been connected to its own water / air supply. The installation effort is very large depending on the number of nozzles (for example 50 to 100). Another disadvantage is that the installation takes place outside the sanitary unit and existing units cannot be retrofitted at all or only with difficulty. Repairs are also difficult or impossible.

Aus der GB 2 069 330 A ist eine Einrichtung der gattungsgemäßen Art mit den Merkmalen des Oberbegriffs von Anspruch 1 bekannt.From GB 2 069 330 A a device of the generic type with the features of the preamble of claim 1 is known.

Bekannte Whirl-Pools weisen weiter eine Absaugeinrichtung auf, zum Beispiel über ein ortsfest montiertes Absaugrohr. Aufgrund des geringen Querschnitts der Absaugleitung ist die Strömungsgeschwindigkeit relativ hoch, was in der Vergangenheit zu Unfällen geführt hat, indem zum Beispiel Kinder mit ihren Haaren in die Absaugleitung gerieten. Dabei wurde vor kurzem sogar ein Todesfall bekannt.Known whirl pools also have a suction device, for example via a fixedly mounted suction pipe. Due to the small cross-section of the suction line the flow speed is relatively high, which has led to accidents in the past, e.g. children with their hair getting into the suction line. One death was recently reported.

Der Erfindung liegt die Aufgabe zugrunde, eine Möglichkeit der konstruktiven Vereinfachung zur Gestaltung von sanitären Apparaten anzubieten, in die Luft und/oder Wasser zur Ausbildung eines "Whirl-Pools" unter Druck eingedüst wird und die eine Absaugeinrichtung für überschüssiges Wasser aufweist. Dabei ist auch eine nachträgliche Umrüstung vorhandener sanitärer Apparate angestrebt.The invention has for its object to offer a possibility of constructive simplification for the design of sanitary appliances, into which air and / or water is injected to form a "whirl pool" under pressure and which has a suction device for excess water. A subsequent retrofitting of existing sanitary equipment is also sought.

Der Erfindung liegt die Erkenntnis zugrunde, daß sich die aus dem Stand der Technik bekannten mannigfaltigen Probleme auf überraschend einfache Weise dadurch lösen lassen, daß au Stelle vereinzelter Öffnungen/Düsen die einzubringende Luft und/oder das einzubringende Wasser über eine kanalartige Leiste zugeführt werden, die zentral an eine Luft- und Wasserzuführung und an eine zentrale Wasserabführung angeschlossen wird und entweder innerhalb (auf der Oberfläche) des sanitären Apparates oder in dessen Boden/Wand angeordnet wird.The invention is based on the knowledge that the manifold problems known from the prior art can be solved in a surprisingly simple manner by supplying the air and / or water to be introduced via a channel-like strip instead of individual openings / nozzles is centrally connected to an air and water supply and to a central water outlet and is arranged either inside (on the surface) of the sanitary apparatus or in its floor / wall.

Die düsenartige Zuführung von Luft/Wasser wird dabei über eine entsprechend perforierte Abdeckung der Leiste sichergestellt. Bei entsprechendem Querschnitt der kanalartigen Leiste kann über die gesamte Fläche der durchbrochenen Abdeckleiste ein gleichmäßiger Druck zur Verfügung gestellt werden.The nozzle-like supply of air / water is ensured by a correspondingly perforated cover on the bar. With a corresponding cross-section of the channel-like strip, a uniform pressure can be provided over the entire surface of the perforated cover strip.

Der Installationsaufwand wird auf ein Minimum reduziert. Mit einer einzigen Zuführleitung werden beliebig viele Düsen über die kanalartige Leiste mit Luft und/oder Wasser versorgt. Die Verbindung zwischen Badewanne und Leiste kann über eine einfache Muffe erfolgen. Mit einer einzigen Zuleitung von einer Pumpe über die Muffe in die Leiste kann sowohl Luft als auch Wasser eingespeist werden, sofern eine Pumpe der in der DE-PS 35 37 039 beschriebenen Art verwendet wird.The installation effort is reduced to a minimum. With a single supply line, any number of nozzles are supplied with air and / or water via the channel-like strip. The connection between the bathtub and the bar can be made using a simple sleeve. Both air and water can be fed in with a single supply line from a pump via the sleeve into the strip, provided a pump of the type described in DE-PS 35 37 039 is used.

Durch die Verbindung der Leiste mit einer Abwasserleitung wird überschüssiges Wasser abgeführt, wobei wiederum eine Pumpe zur Absaugung dient. Da die Absaugleitung unterhalb der Abdeckung liegt, die nur kleine Öffnungen aufweist, besteht nicht mehr die Gefahr, daß zum Beispiel Haare einer im Whirl-Pool sitzenden Person von der Absaugleitung angesaugt werden.Excess water is drained off by connecting the bar to a sewage pipe, again using a pump for suction. Since the suction line lies below the cover, which has only small openings, there is no longer any danger that, for example, hair of a person sitting in the whirlpool will be sucked in by the suction line.

Durch eine entsprechende Schrägstellung der Leiste beziehungsweise eine Ausbildung des Bodens der Leiste mit Neigung wird sichergestellt, daß auch nach Ablassen des Wassers aus der Badewanne in der Leiste kein Restwasser verbleibt. Hierdurch wird die Hygiene deutlich verbessert.A corresponding inclination of the bar or a design of the bottom of the bar with an incline ensures that no residual water remains in the bar even after the water has been drained from the bathtub. This significantly improves hygiene.

In ihrer allgemeinsten Ausführungsform betrifft die Erfindung eine Einrichtung nach Anspruch 1.In its most general embodiment, the invention relates to a device according to claim 1.

Wird die Leiste nachträglich in einer vorhandenen Badewanne angeordnet, so bietet es sich an, die Abdeckung so auszubilden, daß sie die seitlichen Wände der Leiste überragt und in der Innenfläche der Wanne ausläuft. Die Abdeckung hat dabei also eine gewölbte Form. Gleichzeitig wird eine Verletzungsgefahr aufgrund fehlender Kanten ausgeschlossen.If the bar is subsequently arranged in an existing bathtub, it is advisable to design the cover so that it projects beyond the side walls of the bar and runs out in the inner surface of the tub. The cover has an arched shape. At the same time, a risk of injury due to missing edges is excluded.

Da die Leiste nur eine geringe Bauhöhe besitzen muß (zum Beispiel 2 cm), stört sie auch bei nachträglichem Aufbringen auf den Boden oder die Wand der Wanne nicht. Die Leiste kann im übrigen eine beliebige Länge und Breite aufweisen. Sie kann in der Aufsicht eine Rechteckform, ebenso aber auch eine Kreisform oder dergleichen besitzen. Die Leiste kann auch als Ring ausgebildet werden.Since the bar only has to have a low overall height (for example 2 cm), it does not interfere with subsequent application to the floor or the wall of the tub. The bar can also have any length and width. It can have a rectangular shape when viewed from above, but it can also have a circular shape or the like. The bar can also be designed as a ring.

Die Öffnungen der Abdeckung sollten einen Durchmesser von 2 mm nicht überschreiten. Hierdurch wird fast vollständig ausgeschlossen, daß Fremdkörper durch die Abdekkung abgesaugt werden.The openings in the cover should not exceed 2 mm in diameter. As a result, it is almost completely ruled out that foreign bodies are sucked off through the cover.

Die Öffnungen können auch in Form von Düsen gestaltet werden, die richtungsverstellbar in der Abdeckung befestigt sind. Die Düsen können aus Kugeln bestehen, die eine mittige Bohrung aufweisen und in einer korrespondierenden, in der Abdeckung befestigten Aufnahme drehbar gelagert sind. Auf diese Weise kann die Austrittsrichtung des Luft- und/oder Wasserstromes von außen eingestellt werden.The openings can also be designed in the form of nozzles which are fixed in the cover in a directionally adjustable manner. The nozzles can consist of balls that have a central bore and are rotatably mounted in a corresponding receptacle fastened in the cover. In this way, the direction of exit of the air and / or water flow can be adjusted from the outside.

Die Abdeckung ist abnehmbar, um eine Reinigung der Leiste zu ermöglichen. Auch hierin liegt ein wesentlicher Vorteil der erfindungsgemäßen Einrichtung, weil Nässezonen, in denen sich Schmutzteilchen und Krankheitserreger sammeln können, vermieden werden.The cover is removable to allow cleaning of the bar. This is also an essential advantage of the device according to the invention, because wet zones in which dirt particles and pathogens can collect are avoided.

Dabei kann die Abdeckung beispielsweise mit Hilfe von Clips auf die Wände der Leiste aufgesteckt werden.The cover can be attached to the walls of the bar, for example with the help of clips.

Um die Luft-/Wasser-Zuführung von der Wasserabsaugung zu trennen ist die Leiste in verschiedene, voneinander getrennte Zonen unterteilt. Im einfachsten Fall geschieht dies dadurch, daß in Längsrichtung der Schiene vertikale Zwischenwände angeordnet werden. Ebenso ist es aber möglich, die Zone zur Luft-/Wasserzuführung von einer Art Ringkanal zur Absaugung zu umgeben, wie dies in der nachfolgenden Figurenbeschreibung noch näher erläutert wird.In order to separate the air / water supply from the water suction, the bar is divided into different, separate zones. In the simplest case, this is done by arranging vertical partition walls in the longitudinal direction of the rail. However, it is also possible to surround the zone for air / water supply with a kind of ring channel for suction, as will be explained in more detail in the following description of the figures.

In jedem Fall wird mindestens eine Zone an die Luft- und/oder Wasserzuführung und mindestens eine Zone an die Wasserabführleitung angeschlossen.In any case, at least one zone is connected to the air and / or water supply and at least one zone to the water discharge line.

Um einen Rücklauf des eingedüsten Wassers zu verhindern, kann in der Zuführleitung oder dem Anschlußbereich der Zuführleitung zur Leiste ein Rückschlagventil angeordnet werden.A check valve can be arranged in the feed line or in the connection area of the feed line to the bar in order to prevent the water injected from flowing back.

Die Querschnittsform der Leiste ist im übrigen beliebig. Während sich für einen nachträglichen Einbau eine Rechteckform mit geringer Höhe und einer in Bezug auf die Innenfläche der Badewanne konvexe Abdeckung anbietet, kann die Leiste zur Konfektionierung an neu hergestellten Badewannen zum Beispiel auch eine Halbkreisform aufweisen und von außen im Bereich einer korrespondierenden Nut im Boden oder der Wand der Badewanne befestigt werden. Ebenso wird aber auch vorgeschlagen, die erfindungsgemäße Einrichtung mit der Wanne integral auszubilden. Auch dies wird nachstehend noch näher erläutert.The cross-sectional shape of the bar is otherwise arbitrary. While a rectangular shape with a low height and a convex cover with respect to the inner surface of the bathtub is suitable for retrofitting, the bar for assembly on newly manufactured bathtubs can also have a semicircular shape, for example, and from the outside in the area of a corresponding groove in the floor or be attached to the wall of the bathtub. However, it is also proposed to form the device according to the invention integrally with the tub. This is also explained in more detail below.

Gegenstand der Erfindung ist auch ein mit der vorgenannten Einrichtung ausgebildeter sanitärer Badeapparat nach den Ansprüchen 9 und 10.The invention also relates to a sanitary bath apparatus designed with the aforementioned device according to claims 9 and 10.

Um Verbindungsstellen zwischen der Wanne und der Einrichtung zu verhindern, die gegebenenfalls eine Anlagerung von Schmutzteilchen oder Bakterien ermöglichen, soll also die Einrichtung integraler Bestandteil der Wanne sein. Dies kann zum Beispiel dadurch erfolgen, daß die Leiste aus dem Boden oder der Wand der Wanne mit ausgeformt wird. Es sind dann nur noch die entsprechenden Anschlüsse und eine Abdeckung vorzusehen.In order to prevent connection points between the tub and the device, which may allow dirt or bacteria to accumulate, the device should therefore be an integral part of the tub. This can be done, for example, by molding the bar from the bottom or the wall of the tub. Then only the corresponding connections and a cover are to be provided.

Weitere Merkmale der Erfindung ergeben sich aus den Merkmalen der Unteransprüche sowie den sonstigen Anmeldungsunterlagen.Further features of the invention result from the features of the subclaims and the other application documents.

Die in den Figuren 1, 2 dargestellte Badewanne 10 weist im Boden 12 eine Öffnung 14 auf, von der ein Abflußrohr 16 und ein konzentrisch darin angeordnetes Zuführrohr 18 nach außen verlaufen, wobei das Zuführrohr 18 das Abflußrohr 16 im Krümmungsbereich bei 20 durchragt.The bathtub 10 shown in FIGS. 1, 2 has an opening 14 in the base 12, from which an outflow pipe 16 and a supply pipe 18 arranged concentrically therein extend outwards, the supply pipe 18 being the outflow pipe 16 protrudes in the curvature area at 20.

Das Zuführrohr 18 ist mit einer (nicht dargestellten) Pumpe verbunden, über die ein Luft-/Wasser-Gemisch unter Druck in die Wanne 10 zugeführt wird.The feed pipe 18 is connected to a pump (not shown) via which an air / water mixture is fed into the tub 10 under pressure.

Zu diesem Zweck ist auf dem Boden 12 der Wanne 10 eine im Schnitt U-förmige Leiste 22 befestigt und mit dem Zuführrohr 18 dicht verbunden. Die Leiste 22 wird oben von einer in Bezug auf den Boden 12 konvexen Abdeckung 24 begrenzt, die über die Seitenwände 26 der Leiste 22 hinaussteht und in die Innenfläche des Bodens 12 ausläuft. Wie Figur 2 zu entnehmen ist, überragt die Abdeckung 24 die Leiste 22 auch am vorderen und hinteren Ende, so daß in der Aufsicht (Figur 3) eine ovale Grundfläche abgedeckt wird. Unterhalb des überstehenden Teils der Abdeckung 24 verläuft das Abflußrohr 16.For this purpose, a section 22 which is U-shaped in section is fastened to the bottom 12 of the tub 10 and is tightly connected to the feed pipe 18. The strip 22 is delimited at the top by a cover 24 which is convex with respect to the base 12 and which projects beyond the side walls 26 of the strip 22 and runs out into the inner surface of the base 12. As can be seen in FIG. 2, the cover 24 also projects beyond the strip 22 at the front and rear ends, so that an oval base area is covered in the view (FIG. 3). The drain pipe 16 runs below the protruding part of the cover 24.

Das Luft-/Wasser-Gemisch wird über das Zuführrohr 18 in den Raum zwischen Leiste 22 und Abdeckung 24 geführt und über die in der Abdeckung 24 befindlichen Öffnungen 28 in das in der Wanne 10 befindliche Wasser eingedüst.The air / water mixture is fed via the feed pipe 18 into the space between the strip 22 and the cover 24 and is injected into the water in the tub 10 via the openings 28 in the cover 24.

Auch der die Leiste 22 überragende Abschnitt der Abdekkung 24 weist Öffnungen (Perforationen) auf, über die das Wasser in den darunter liegenden Abschnitt 32 gelangt, von wo es über das Abflußrohr 16 weggeführt wird.The section of the cover 24 projecting beyond the strip 22 also has openings (perforations) through which the water reaches the section 32 below, from where it is led away via the drain pipe 16.

Mit einer einzigen Zuführung (Zuführrohr 18) kann aufgrund der erfindungsgemäßen Einrichtung praktisch die gesamte Bodenfläche der Wanne 10 als "Düsenfläche" ausgebildet werden, wie Figur 3 zeigt. Die Einrichtung kann darüber hinaus problemfrei nachgerüstet werden, wobei sogar der vorhandene Abfluß der Wanne zum Anschluß der genannten Rohre genutzt werden kann. Durch einfaches Abnehmen der lösbar auf der Leiste 22 befestigten Abdekkung 24 ist die Einrichtung leicht zu reinigen. Aufgrund ihrer zum Abflußrohr 16 hin geneigten Anordnung läuft außerdem beim Ablassen des Wassers 30 Restwasser automatisch ab.With a single feed (feed tube 18), practically the entire bottom surface of the tub 10 can be formed as a "nozzle surface" due to the device according to the invention, as shown in FIG. 3. The device can also be easily retrofitted, and even the existing drain of the tub can be used to connect the pipes mentioned. By simply taking it off the cover 24 releasably attached to the bar 22, the device is easy to clean. Because of its inclined arrangement towards the drain pipe 16, 30 residual water also runs off automatically when the water is drained.

Während sich die in den Figuren 1 bis 3 dargestellte Ausführungsform vor allem zur Nachrüstung vorhandener Wannen anbietet, zeigen die Figuren 4 bis 7 alternative Ausführungsformen, die besonders bei neuen Wannen vorteilhaft realisiert werden können.While the embodiment shown in FIGS. 1 to 3 is particularly suitable for retrofitting existing tubs, FIGS. 4 to 7 show alternative embodiments that can be advantageously implemented particularly in the case of new tubs.

Bei der Wanne nach Figur 4 sind im Boden 2 Bohrungen 32, 34 vorhanden, wobei die Bohrung 32 zum Anschluß eines Luft-/Wasser-Zuführrohres 18 und die Bohrung 34 zum Anschluß eines Abflußrohres 16 dienen.In the trough according to FIG. 4, there are two holes 32, 34 in the bottom, the hole 32 serving to connect an air / water supply pipe 18 and the hole 34 serving to connect a drain pipe 16.

Die Leitung 18 mündet in den Bereich der Wanne 10, der von einer ersten Abdeckung 24 abgedeckt ist, die - ähnlich wie in Figur 1 - in Längsrichtung der Wanne verläuft und mit einer Vielzahl von Öffnungen (hier: 80 Stück, verteilt über die Länge und Breite der Abdeckung) ausgebildet ist.The line 18 opens into the area of the tub 10, which is covered by a first cover 24, which - similar to FIG. 1 - runs in the longitudinal direction of the tub and with a large number of openings (here: 80 pieces, distributed over the length and Width of the cover) is formed.

Die weitere Abdeckung 24 verläuft parallel dazu und überdeckt den Bereich des Abflußrohres 16. Beide Abdeckungen sind auf Clips am Wannenboden lösbar aufgesteckt.The further cover 24 runs parallel to it and covers the area of the drain pipe 16. Both covers are detachably attached to clips on the tub floor.

Während also über das Zuführrohr 18 und die Bohrung 22 das Luft-/Wasser-Gemisch zugeführt wird, wird überschüssiges Wasser durch die in Figur 4 linke Abdeckung 24 über die Bohrung 34 und das Abflußrohr 16 weggeführt.Thus, while the air / water mixture is supplied via the feed pipe 18 and the bore 22, excess water is led away through the cover 24 on the left in FIG. 4 via the bore 34 and the drain pipe 16.

Beim Ausführungsbeispiel nach Figur 4 werden der Boden 22a und die Seitenwände 26 der Leiste 22 vom Boden 12 der Wanne 10 beziehungsweise den gewölbten Abschnitten der Abdeckung 24 selbst gebildet.In the embodiment of Figure 4, the bottom 22a and the side walls 26 of the bar 22 from the bottom 12 of the Trough 10 or the curved portions of the cover 24 itself formed.

Beim Ausführungsbeispiel nach Figur 5 ist der Boden 12 der Wanne 10 mit einer sickenförmigen kanalartigen Vertiefung ausgebildet, die sich in Längsrichtung der Wanne erstreckt und von einer Abdeckung 24 oben begrenzt wird, die bündig mit der Innenfläche des Bodens 12 abschließt.In the exemplary embodiment according to FIG. 5, the bottom 12 of the tub 10 is formed with a bead-like channel-like depression which extends in the longitudinal direction of the tub and is delimited at the top by a cover 24 which is flush with the inner surface of the bottom 12.

Der hierdurch ausgebildete Raum 38 wird durch zusätzliche Zwischenwände 40 in drei Abschnitte unterteilt, wobei der mittlere Abschnitt 40a zur Zuführung des Luft-/Wasser-Gemisches und die seitlichen Zonen 40b der Wasserrückführung dienen, und zwar auf die zuvor beschriebene Art und Weise.The space 38 formed in this way is divided into three sections by additional partition walls 40, the middle section 40a serving for supplying the air / water mixture and the lateral zones 40b serving for water return, in the manner described above.

Selbstverständlich sind die einzelnen Zonen - wie oben beschrieben - wieder an ein Zuführ- beziehungsweise Abflußrohr angeschlossen. Ein Vorteil der Ausführungsform nach Figur 5 besteht darin, daß keine in die Wanne vorspringenden Teile mehr vorhanden sind. Auch hier ist die Abdeckung 24 lösbar auf die Zwischenwände 40 aufgesteckt, so daß sie leicht abgenommen werden kann. Hierdurch wird eine Möglichkeit zur Reinigung sowie ein hoher Hygienestandard erreicht. Bei vorhandenen Wannen kann diese Ausführungsform dadurch realisiert werden, daß der Boden aufgeschnitten und eine Leiste von unten - entsprechend Figur 5 - angesetzt wird.Of course, the individual zones - as described above - are connected again to a feed or drain pipe. An advantage of the embodiment according to FIG. 5 is that there are no longer any parts projecting into the tub. Again, the cover 24 is releasably attached to the intermediate walls 40 so that it can be easily removed. This provides an opportunity for cleaning and a high standard of hygiene. In the case of existing tubs, this embodiment can be realized in that the bottom is cut open and a strip is attached from below - according to FIG. 5.

Das Ausführungsbeispiel nach Figur 6 ist ähnlich dem nach Figur 5, wobei hier die einzelnen Zonen jedoch nicht nebeneinander, sondern wie folgt angeordnet sind: Die Zone 40a zur Zuführung des Luft-/Wasser-Gemisches wird durch Zwischenwände 40 von einem U-förmigen Kanal 40b getrennt, der zur Wasserrückführung dient. Im Gegensatz zum Ausführungsbeispiel nach Figur 5 ist hier der Rückführkanal nicht neben die Zuführzone, sondern um diese herum gelegt. Hierdurch wird die Bauhöhe der Vertiefung 36 größer; die Breite gleichzeitig geringer.The exemplary embodiment according to FIG. 6 is similar to that according to FIG. 5, but here the individual zones are not arranged next to one another, but rather as follows: The zone 40a for supplying the air / water mixture is separated by a wall 40 from a U-shaped channel 40b separated, which is used for water return. In contrast to the exemplary embodiment according to FIG. 5, the return duct is not placed next to the feed zone, but rather around it. As a result, the overall height of the recess 36 greater; the width is smaller at the same time.

Das Ausführungsbeispiel nach Figur 7 entspricht mit einer Ausnahme dem nach Figur 6. Die Abdeckung 24 fluchtet hier nicht mit der Innenfläche des Bodens 12, sondern ist - ähnlich wie in Figur 1 - gewölbt ausgebildet und überragt die Vertiefung 36 beidseitig. Sie ist selbstverständlich wieder abnehmbar.The embodiment according to FIG. 7 corresponds, with one exception, to that according to FIG. 6. The cover 24 does not align with the inner surface of the bottom 12 here, but is - similar to that in FIG. 1 - curved and projects beyond the recess 36 on both sides. It is of course removable again.

In allen Fällen sind die sanitären Anschlüsse auf gleiche Art und Weise ausgeführt, wie anhand des Ausführungsbeispieles nach den Figuren 1 bis 3 beschrieben.In all cases, the sanitary connections are carried out in the same manner as described using the exemplary embodiment according to FIGS. 1 to 3.
