Abstract

The flood unit, for use in a bathroom head shower or outflow fitting, has a housing (2) with a water inlet (4) and a longitudinal outflow slit so that the water flows out in a coherent curtain. Flow calming units are within the housing, to form an ante-chamber (5) to take the water inflow. The water flows from the chamber into a build-up zone (12), parallel to the outflow slit and over its whole length. The build-up zone is linked to the outflow slit through a narrow gap into the outflow zone (13) with the outflow slit. The water flow through the assembly is divided and calmed, to give an outflow curtain without pressure and movement only through the force of gravity, and retain its curtain shape over a long movement path from the outflow slit.

Description

Die Erfindung betrifft eine Schwalleinrichtung zur Verwendung in einer sanitären Kopfbrause oder in einer sanitären Auslaufarmatur mit

  1. a) einem Gehäuse, das einen Wassereinlaß aufweist;
  2. b) strömungsberuhigenden Einbauten innerhalb des Gehäuses;
  3. c) einem länglichen Auslaufschlitz, über den Wasser das Gehäuse in einem zusammenhängenden Vorhang verläßt.
The invention relates to a surge device for use in a sanitary overhead shower or in a sanitary outlet fitting with
  1. a) a housing having a water inlet;
  2. b) flow-calming internals within the housing;
  3. c) an elongated outlet slot through which water leaves the housing in a continuous curtain.

Die Anforderungen an den Komfort moderner Sanitäreinrichtungen, insbesondere auch an Brauseeinrichtungen und Auslaufarmaturen, wachsen ständig. So stellt der Benutzer auch Anforderungen an die Art des Strahls, welcher diese Sanitäreinrichtungen verläßt. Bei Brausen sind sehr unterschiedliche Strahlarten gewünscht, so beispielsweise harte, massierende Strahlen, weichere, mit Luftbläschen angereicherte Strahlen und in jüngster Zeit auch "Wasservorhänge". Bei letzteren handelt es sich um Wassergebilde, welche im wesentlichen drucklos unter dem Einfluß der Schwerkraft einen entsprechenden Auslaufschlitz verlassen und beim Benutzer, insbesondere im Fall von Kopfbrausen, eine besonders angenehme Empfindung hinterlassen. Bei derartigen "Wasservorhängen" ist es wichtig, daß sie sich während des freien Falls auf eine möglichst große Strecke hin nicht unterteilten, also geschlossen bleiben und nicht zusammenfallen.The demands on the comfort of modern sanitary facilities, especially on shower facilities and outlet fittings, are constantly growing. Thus, the user also makes demands on the type of jet leaving these sanitary facilities. In showers very different types of spray are desired, such as hard, massaging rays, softer, enriched with air bubbles and, more recently, "water curtains". The latter are water structures, which leave a corresponding outlet slit substantially under pressure under the influence of gravity and leave the user, especially in the case of overhead showers, a particularly pleasant sensation. In such "water curtains", it is important that they do not subdivide during the free fall to the greatest possible extent, so remain closed and do not coincide.

Eine Schwalleinrichtung der eingangs genannten Art, die zur Verwendung in Kopfbrausen bestimmt ist, ist in der DE 26 19 415 C2 beschrieben. Hier wird versucht, durch eine Abwinkelung des Strömungswegs zwischen dem Einlaß in das Gehäuse und dem Auslaßschlitz sowie durch eine sich kontinuierlich von einem runden Querschnitt zu einem schlitzförmigen Querschnitt verändernde Form des Gehäuses einen "stabilen" Wasservorhang zu erzeugen. Dabei werden unterstützende, strömungsleitende Rippen eingesetzt, die an die Innenseite des Gehäuses angeformt sind. Auch bei dieser bekannten Schwalleinrichtung ist jedoch der sich bildende Wasservorhang noch nicht in der gewünschten Weise stabil.A surge device of the type mentioned, which is intended for use in overhead showers, is in DE 26 19 415 C2 described. An attempt is made here to produce a "stable" water curtain by bending the flow path between the inlet into the housing and the outlet slot and by continuously changing the shape of the housing from a circular cross section to a slot-shaped cross section. In this case, supporting, flow-conducting ribs are used, which are integrally formed on the inside of the housing. Even with this known surge device, however, the forming water curtain is not yet stable in the desired manner.

Schwalleinrichtungen, die auf ähnlichen Konstruktionsprinzipien beruhen und für sanitäre Auslaufarmaturen gedacht sind, sind in der DE 39 15 357 A1 bzw. der DE 41 33 639 C1 beschrieben. Hier wird mit dem Konzept gearbeitet, das Wasser nach dem Austritt aus dem eigentlichen Auslaßschlitz entlang einer verhältnismäßig großen Führungsfläche strömen zu lassen, bevor es dann sich als Wasservorhang von dieser Führungsfläche löst. Erneut sind die Ergebnisse, die auf diese Weise hinsichtlich der Stabilität des Wasservorhangs erzielt werden, noch nicht voll zufriedenstellend.Schwalleinrichtungen based on similar design principles and are intended for sanitary outlet fittings are in the DE 39 15 357 A1 or the DE 41 33 639 C1 described. Here is worked with the concept of allowing the water to flow after exiting the actual outlet slot along a relatively large guide surface before it then dissolves as a curtain of water from this guide surface. Again, the results obtained in this way with respect to the stability of the water curtain are not yet fully satisfactory.

Aufgabe der vorliegenden Erfindung ist es, eine Schwalleinrichtung der eingangs genannten Art so auszugestalten, daß ein hochstabiler Wasservorhang erzielt wird, der über eine verhältnismäßig große Strecke frei fallen kann, bevor er sich unterteilt oder zusammenfällt.Object of the present invention is to provide a surge device of the type mentioned in such a way that a highly stable water curtain is achieved, which can fall freely over a relatively large distance before it is divided or coincident.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die strömungsberuhigenden Einbauten bilden:

  • d) einen Vorraum, in den das Wasser aus dem Wassereinlaß gelangt;
  • e) einen Stauraum, in welchen das Wasser aus dem Vorraum gelangt und der parallel zum Auslaufschlitz über dessen gesamte Längserstreckung verläuft;
  • f) einen mit dem Stauraum über einen schmalen Schlitz verbundenen Auslaufraum, in dem der Auslaufschlitz angeordnet ist, wobei Auslaufraum und Stauraum durch einen inneren Wandabschnitt voneinander getrennt sind, der nicht über die gesamte Höhe des Gehäuses verläuft.
This object is achieved in that form the flow-calming internals:
  • d) an anteroom, in which the water from the water inlet arrives;
  • e) a storage space, in which the water passes from the vestibule and runs parallel to the outlet slot over its entire longitudinal extent;
  • f) a discharge space connected to the storage space via a narrow slot, in which the outlet slot is arranged, wherein discharge space and storage space are separated by an inner wall portion, which does not extend over the entire height of the housing.

Erfindungsgemäß wird sehr sorgfältig darauf geachtet, daß der Druck des aus der Hausleitung strömenden Wassers vor Erreichen des Auslaufschlitzes praktisch vollständig abgebaut ist, daß Wirbel und andere Strömungsunregelmäßigkeiten sich bis zum Erreichen des Auslaufschlitzes beruhigt haben und daß das Wasser den Auslaufschlitz über seine gesamte Längserstreckung hinweg in gleichen Mengen erreicht. Der erfindungsgemäß vorgesehene Vorraum ermöglicht zunächst eine Entspannung des Wassers innerhalb eines verhältnismäßig großen Volumens und eine Beruhigung der in diesem Zusammenhang entstehenden Wirbel. Das Wasser, welches den Vorraum verläßt und in den Stauraum eintritt, befindet sich also praktisch bereits auf dem Druck der Außenatmosphäre und hat seine kinetische Energie weitgehend verloren. Der Stauraum verteilt nunmehr das Wasser über eine Länge, die der Länge des Auslaufschlitzes entspricht, ohne selbst direkt mit dem Auslaufschlitz verbunden zu sein. Die abschließende Beruhigung und Vergleichmäßigung des Wasserstroms erfolgt vielmehr beim Passieren einer Art von "Wehr", das von einem Wandabschnitt im Inneren des Gehäuses gebildet wird, der einen Durchtrittsspalt zu einem benachbarten Auslaufraum freiläßt. Über diesen Spalt tritt in den Auslaufraum, der den eigentlichen Auslaufschlitz enthält, an allen Stellen über die Längserstreckung hinweg Wasser in praktisch druckfreiem Zustand, das wirbelfrei ist und an allen Stellen das gleiche Volumen pro Zeiteinheit transportiert. Dieses Wasser kann nunmehr in höchster Gleichmäßigkeit den Auslaufschlitz passieren und als geschlossener, stabiler Vorhang nach unten fallen.According to the invention care is taken very carefully that the pressure of the water flowing from the house water is almost completely dissipated before reaching the outlet slit, that vortex and other flow irregularities have calmed to reach the outlet slit and that the water the outlet slit over its entire longitudinal extent in reached equal amounts. The inventively provided antechamber initially allows a relaxation of the water within a relatively large volume and a calming of the resulting vortex in this context. The water leaving the vestibule and entering the storage space is thus practically already at the pressure of the outside atmosphere and has largely lost its kinetic energy. The storage space now distributes the water over a length corresponding to the length of the outlet slot without itself being directly connected to the outlet slot. The final calming and evening out of the water flow is rather when passing through a type of "weir", which is formed by a wall portion in the interior of the housing, which leaves a passage gap to an adjacent outlet space. About this gap occurs in the outlet space, which contains the actual outlet slot, at all points over the longitudinal extent of water in virtually pressure-free state, which is vortex-free and transported at all points the same volume per unit time. This water can now pass through the outlet slot in the highest uniformity and fall down as a closed, stable curtain.

Zweckmäßigerweise ist der Auslaufschlitz bogenförmig gekrümmt. Auf diese Weise ist es möglich, einen sehr langen, viel Wasser führenden Wasservorhang in einer Schwalleinrichtung zu erzeugen, deren Dimensionen nicht allzu groß sind.Conveniently, the outlet slot is arcuately curved. In this way, it is possible to produce a very long, water-rich curtain of water in a surge device whose dimensions are not too large.

Vorteilhafterweise ist das Gehäuse aus einem Gehäuseunterteil und einem durch eine Steckverbindung mit dem Gehäuseunterteil verbundenen Deckel gebildet. Diese zweitteilige Ausgestaltung der Schwalleinrichtung erleichtert deren Herstellung und Montage, wobei es auf eine absolute Dichtigkeit zwischen den beiden miteinander zu verbindenden Gehäuseteilen nicht ankommt. Im allgemeinen reicht hierfür eine Labyrinthdichtung aus. Ggf. können aber die beiden Gehäuseteile nach dem Zusammenstecken auch dicht verschweißt werden.Advantageously, the housing is formed of a lower housing part and a lid connected by a plug connection with the lower housing part. This two-part design of the swelling device facilitates their manufacture and assembly, wherein it does not depend on an absolute tightness between the two housing parts to be joined together. In general, this is sufficient for a labyrinth seal. Possibly. But the two housing parts can also be welded tight after plugging together.

Bei einer besonders bevorzugten Ausführungsform der Erfindung ist der Auslaufschlitz an der Außenseite des Gehäuses von einer Rippe umgeben. Schwalleinrichtungen der hier interessierenden Art werden ja innerhalb eines Außengehäuses, z. B. innerhalb des Sichtgehäuses der Brause oder der Auslaufarmatur, untergebracht. Die den Auslaufschlitz umgebende Rippe durchsetzt in diesem Fall das Sichtgehäuse der Brause oder der Auslaufarmatur, während alle anderen Teile der Schwalleinrichtung von diesem Sichtgehäuse verborgen sind. Die das Sichtgehäuse durchsetzende Rippe verhindert, daß der den Auslaufschlitz verlassende Wasservorhang an Trennflächen vorbeiströmen muß, die die innere Stabilität des Wasservorhang gefährden könnten.In a particularly preferred embodiment of the invention, the outlet slot on the outside of the housing is surrounded by a rib. Schwalleinrichtungen of interest here type are indeed within an outer housing, z. B. housed within the viewing housing of the shower or the outlet fitting. The rib surrounding the outlet slot in this case passes through the visual housing of the shower or the outlet fitting, while all other parts of the surge device are hidden by this viewing housing. The the sight housing penetrating rib prevents the water curtain leaving the outlet slot must flow past interfaces that could jeopardize the internal stability of the water curtain.

Eine weitere Verbesserung der Qualität des Wasservorhangs wird durch diejenige Ausgestaltung der Erfindung erzielt, bei welcher im Strömungsweg zwischen dem Vorraum und dem Stauraum ein Verteilraum angeordnet ist, der mit dem Stauraum über eine Öffnung in einem zwischenliegenden Wandabschnitt verbunden ist, welcher etwa in der Mitte der Längserstreckung des Stauraums liegt. Durch diese Ausgestaltung wird erreicht, daß die Wasserverteilung innerhalb des Stauraums zumindest annähernd symmetrisch ist, wodurch ebenfalls Druckunterschiede innerhalb des Stauraums auf ein Minimum reduziert werden.A further improvement of the quality of the water curtain is achieved by that embodiment of the invention in which a distribution space is arranged in the flow path between the vestibule and the storage space, which is connected to the storage space via an opening in an intermediate wall portion, which approximately in the middle of Longitudinal extent of the storage space is located. This configuration ensures that the water distribution within the storage space is at least approximately symmetrical, which also reduces pressure differences within the storage space to a minimum.

Die in Figur 1 dargestellte und insgesamt mit dem Bezugszeichen 1 gekennzeichnete Schwalleinrichtung ist zum Einbau in eine Kopfschwallbrause bestimmt. Sie umfaßt ein Gehäuse 2, das im wesentlichen nierenförmig gekrümmt ist und aus einem Gehäuseunterteil 3 (Figur 3) und einem Deckel (Figur 2) zusammengesetzt ist.The illustrated in Figure 1 and generally designated by the reference numeral 1 Schwullinrichtung is intended for installation in a Kopfschwallbrause. It comprises a housing 2, which is substantially kidney-shaped and is composed of a lower housing part 3 (Figure 3) and a lid (Figure 2).

Zur weiteren Beschreibung wird für Baukomponenten, die im wesentlichen parallel zu den bogenförmig gekrümmten Seitenwänden des Gehäuses 1 verlaufen, der Begriff "azimutal" und für solche Baukomponenten, die im wesentlichen senkrecht zu diesen azimutalen Baukomponenten verlaufen, der Begriff "radial" verwendet, obwohl die "azimutalen" Baukomponenten keine echten Kreisbögen bilden.For further description, the term "azimuthal" is used for structural components that run substantially parallel to the arcuately curved side walls of the housing 1 and the term "radial" for those structural components that run essentially perpendicular to these azimuthal structural components, although the "azimuthal" building components do not form true circular arcs.

Das Gehäuseunterteil 2 weist an einem Ende einen Wassereinlaß 4 auf, der mit einem nicht dargestellten Wasserzuflußrohr verbunden werden kann. Durch den Wassereinlaß 4 gelangt das zuströmende Wasser in einen Vorraum 5, der sich in azimutaler Richtung um etwa 40 % der gesamten Erstreckung des Gehäuseunterteils 2 erstreckt. Durch einen radial verlaufenden inneren Wandabschnitt 6 und einen an diesen angeformten azimutalen Wandabschnitt 7 verengt sich der Vorraum 5 in Figur 3 nach rechts in einen schmäleren, ebenfalls azimutal verlaufenden Verteilraum 8. Etwa in der Mitte seiner Längserstreckung hat der azimutale Wandabschnitt 7 eine seine Höhe reduzierende rechteckige Vertiefung 9.The lower housing part 2 has at one end a water inlet 4, which can be connected to a Wasserzuflußrohr, not shown. Through the water inlet 4, the inflowing water passes into an antechamber 5, which extends in the azimuthal direction by about 40% of the total extent of the housing lower part 2. By a radially extending inner wall portion 6 and an integrally formed on this azimuthal wall portion 7 narrows the vestibule 5 in Figure 3 to the right in a narrower, also azimuthally extending distribution space 8. Approximately in the middle of its longitudinal extension of the azimuthal wall portion 7 has a height reducing rectangular recess 9.

Parallel zum azimutalen Wandabschnitt 7 verläuft mit etwas größerem "Radius" ein weiterer azimutaler Wandabschnitt 10, der von dem radialen Wandabschnitt 6 ausgeht und sich bis zur in Figur 3 rechten Stirnwand 11 des Gehäuseunterteils 2 erstreckt. Während die Wandabschnitte 6 und 7 eine Höhe besitzen, bei der sie nach Anbau des Deckels 3 im wesentlichen an die Innenfläche des Deckels 3 anstoßen, ist die Höhe des azimutalen Wandabschnitts 10 etwas reduziert, so daß nach dem Anbau des Deckels 3 an das Gehäuseunterteil 2 zwischen der Innenfläche des Deckels 3 und der Oberseite des azimutalen Wandabschnitts 10 ein gleichmäßiger Spalt verbleibt. Zwischen den Wandabschnitten 7 und 10 befindet sich ein azimutal verlaufender Stauraum 12, zwischen dem azimutal verlaufenden Wandabschnitt 10 und der azimutal verlaufenden Begrenzungswand des Gehäuseunterteils 2, welche den größeren Durchmesser aufweist, ein Auslaufraum 13.Parallel to the azimuthal wall portion 7 extends with a slightly larger "radius" another azimuthal wall portion 10, which starts from the radial wall portion 6 and extends to the right in Figure 3 end wall 11 of the housing base 2. While the wall portions 6 and 7 have a height at which they abut substantially after cultivation of the lid 3 to the inner surface of the lid 3, the height of the azimuthal wall portion 10 is slightly reduced, so that after the attachment of the lid 3 to the lower housing part. 2 between the inner surface of the lid 3 and the top of the azimuthal wall portion 10 remains a uniform gap. Between the wall sections 7 and 10 is an azimuthally extending storage space 12, between the azimuthally extending wall portion 10 and the azimuthally extending boundary wall of the lower housing part 2, which has the larger diameter, an outlet space thirteenth

Entlang der gesamten oberen Stirnseite aller Begrenzungswände des Gehäuseunterteils 2 verläuft eine vorstehende Rippe 14. An den Boden des Vorraums 5 sind zwei hohlzylindrische Vorsprünge 15 und 16 angeformt.Along the entire upper end face of all boundary walls of the housing base 2 extends a projecting rib 14. At the bottom of the vestibule 5, two hollow cylindrical projections 15 and 16 are formed.

Der in Figur 2 dargestellte Deckel 3 der Schwalleinrichtung 1 besitzt eine zum Gehäuseunterteil 2 komplementäre Form. An die Innenseite des Deckels 3 ist ebenfalls eine parallel zur Außenkontur verlaufende Rippe 17 angeformt. Die Innenfläche des Deckels 3 trägt außerdem zwei vorstehende Zapfen 18 und 19.The lid 3 of the swelling device 1 shown in Figure 2 has a shape complementary to the housing part 2. On the inside of the lid 3, a parallel to the outer contour extending rib 17 is also formed. The inner surface of the lid 3 also carries two projecting pins 18 and 19th

Der Deckel 3 wird in einem Bereich, welcher im zusammengebauten Zustand dem Auslaufraum 13 des Gehäuseunterteils 2 entspricht, von einem azimutal verlaufenden, schmalen Auslaufschlitz 20 durchsetzt. Wie insbesondere Figur 1 zeigt, ist der Auslaufschlitz 20 an der Außenseite des Deckels 3 von einer vorstehenden Rippe 21 umgeben. Außerdem trägt die Oberseite des Deckels 3 mehrere Versteifungsrippen 22, 23, 24, 25, 26, die im wesentlichen radial ausgerichtet sind.The lid 3 is penetrated by an azimuthally extending, narrow outlet slot 20 in a region which corresponds to the outlet space 13 of the housing lower part 2 in the assembled state. As shown particularly in FIG. 1, the outlet slot 20 on the outside of the lid 3 is surrounded by a protruding rib 21. In addition, the top of the lid 3 carries a plurality of stiffening ribs 22, 23, 24, 25, 26, which are aligned substantially radially.

Beim Aufsetzen des Deckels 3 auf das Gehäuseunterteil der Figur 3 werden die Zapfen 18 und 19 an der Innenseite des Deckels 3 in die Bohrungen der hohlzylindrischen Vorsprünge 15, 16 des Gehäuseunterteils 2 eingeführt. Die Rippe 14 des Gehäuseunterteils 2 umgreift die Rippe 17 des Deckels 3 und bildet so eine formschlüssige Verbindung sowie eine Art Labyrinthdichtung, wobei es auf eine absolute Dichtigkeit nicht ankommt. Ebenso wenig ist es erforderlich, daß es zwischen der Oberseite der Wandabschnitte 6 und 7 des Gehäuseunterteils 2 und der Innenfläche des Deckels 3 zu einer vollständigen Abdichtung kommt.When placing the cover 3 on the lower housing part of Figure 3, the pins 18 and 19 are introduced on the inside of the lid 3 in the holes of the hollow cylindrical projections 15, 16 of the housing part 2. The rib 14 of the lower housing part 2 surrounds the rib 17 of the lid 3 and thus forms a positive connection and a kind of labyrinth seal, wherein it on a absolute tightness does not matter. Nor is it necessary that it comes between the top of the wall portions 6 and 7 of the housing base 2 and the inner surface of the lid 3 to a complete seal.

Grundsätzlich ist es aber auch möglich, Gehäuseunterteil 2 und Deckel 3 nach dem Zusammenfügen in der beschriebenen Weise an der Verbindungsstelle miteinander zu verschweißen, um auf diese Weise eine vollständige Dichtigkeit zu erzielen.In principle, however, it is also possible to weld housing base 2 and cover 3 together after assembly in the manner described at the connection point in order to achieve complete sealing in this way.

Die fertig gestellte Schwalleinrichtung 1 wird in das nicht dargestellte Sichtgehäuse einer Schwallbrause eingebracht, wobei die Rippe 21 einen entsprechenden Spalt dieses Sichtgehäuses durchtritt, während alle anderen Gehäuseteile der Schwalleinrichtung 1 durch das Sichtgehäuse der Brause verborgen sind.The finished surge device 1 is introduced into the visual housing, not shown, a surge shower, wherein the rib 21 passes through a corresponding gap of this view housing, while all other housing parts of the surge device 1 are hidden by the viewing housing of the shower.

Fertig in der Brause montiert ist die Schwalleinrichtung 1 so angeordnet, daß der Auslaufschlitz 20 nach unten zeigt.Finished mounted in the shower, the surge device 1 is arranged so that the outlet slot 20 faces downward.

Im Betrieb der Kopfbrause, welche die beschriebene Schwalleinrichtung 1 enthält, wird dieser über den Wassereinlauf 4 Wasser zugeführt, welches über den Vorraum 5 in den Verteilraum 8 strömt. Von dort gelangt das Wasser über die Vertiefung 9 in dem azimutal verlaufenden Wandabschnitt 7 in den Stauraum 12, wo es sich über dessen gesamt azimutale Länge verteilt. Der azimutal verlaufende Wandabschnitt 10, der eine geringere Höhe als der Wandabschnitt 7 aufweist, bildet eine Art "Wehr", wobei der Spalt zwischen der Stirnseite dieses Wandabschnitts 10 und der Innenfläche des Deckels 3 vom Wasser über die gesamte azimutale Länge hinweg gleichmäßig durchströmt wird.During operation of the overhead shower, which contains the described surge device 1, it is supplied via the water inlet 4 water, which flows through the antechamber 5 in the distribution chamber 8. From there, the water passes through the recess 9 in the azimuthally extending wall portion 7 in the storage space 12, where it is distributed over the entire azimuthal length. The azimuthally extending wall section 10, which has a smaller height than the wall section 7, forms a kind of "weir", wherein the gap between the end face of this wall section 10 and the inner surface of the lid 3 is uniformly flowed through by the water over the entire azimuthal length.

Das auf diese Weise in den Auslaufraum 13 gelangende Wasser tritt nunmehr praktisch druckfrei, ausschließlich unter dem Einfluß der Schwerkraft über den Auslaufschlitz 20 aus und bildet hier einen geschlossenen Wasservorhang, der auch in verhältnismäßig großer Entfernung von dem Auslaufschlitz 20 noch als geschlossener Wasservorhang erhalten bleibt.The reaching in this way in the discharge chamber 13 water now occurs virtually pressure-free, exclusively under the influence of gravity on the outlet slot 20 and here forms a closed water curtain, which is still preserved in a relatively large distance from the outlet slot 20 as a closed curtain water.
