Abstract

In a shower head with water jet nozzles, in particular for sanitary applications, it is proposed, for the sake of preventing calcium deposits in the region of the cross-section producing the jet, that the water jet nozzles each have a nozzle channel whose jet-producing cross-section is constructed upstream of the outlet opening and that in the flow direction the remaining section of the channel with the outlet opening is widened. <IMAGE>

Description

Die Erfindung betrifft einen Brausekopf mit Wasserstrahldüsen, insbesondere für den Sanitärbereich. Eine derartige Brauseeinrichtung ist beispielsweise aus der Druckschrift DE-OS 24 59 316 bekannt. Als Wasserstrahldüsen sind hierbei etwa zylindrische Bohrungen in einer elastisch verformbaren membranartigen Scheibe angeordnet, die im Brausekopfgehäuse gehaltert ist. Beim Betrieb von sanitären Brausen lagern sich Ausscheidungen, insbesondere Kalk aus dem Brausewasser, im Bereich der Wasseraustrittsöffnungen ab und verursachen hier unerwünschte Verkrustungen, die die Funktionsfähigkeit der Brause schon nach relativ kurzer Gebrauchsdauer erheblich beeinträchtigen können. Von Wasserdruckschwankungen verursachte leichte Ausbiegungen der membranartigen Scheibe können zwar vereinzelte Kalkkrusten abbrechen, aber im allgemeinen reichen die Auslenkungen nicht aus, um die Wasseraustrittsöffnungen verkalkungsfrei zu halten. Darüber hinaus erhalten die Brausestrahlen bei der Auslenkung der Membran eine Richtungsänderung, was meist unerwünscht ist.The invention relates to a shower head with water jet nozzles, in particular for the sanitary area. Such a shower device is known for example from the document DE-OS 24 59 316. In this case, approximately cylindrical bores are arranged as water jet nozzles in an elastically deformable membrane-like disc which is held in the shower head housing. During the operation of sanitary showers, excretions, especially lime from the shower water, are deposited in the area of the water outlet openings and cause unwanted incrustations, which can significantly impair the functionality of the shower after a relatively short period of use. Slight bending of the membrane-like disc caused by fluctuations in water pressure can break off occasional lime crusts, but in general the deflections are not sufficient to keep the water outlet openings free of calcification. In addition, the shower jets receive a change in direction when the membrane is deflected, which is usually undesirable.

Der Erfindung liegt die Aufgabe zugrunde, die Wasserstrahldüsen im Brausekopf so auszubilden, daß die Kalkausscheidungen aus dem Brausewasser im wesentlichen unschädlich außerhalb des Strahlerzeugungsquerschnitts erfolgen.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Wasserstrahldüsen jeweils einen Düsenkanal aufweisen, dessen Strahlerzeugungsquerschnitt stromaufwärts vor der Austrittsöffnung ausgebildet und in Fließrichtung die restliche Kanalstrecke mit der Austrittsöffnung erweitert ist. Mit diesen Maßnahmen wird erreicht, daß bei einer Nichtbenutzung der Brause die Verdunstung des Wassers im Bereich der erweiterten Austrittsöffnungen erfolgt und die hierbei auftretenden Kalkabscheidungen somit in diesem Bereich unschädlich erfolgen. Im Bereich des weiter stromaufwärts gelegenen Strahlerzeugungsquerschnitts werden damit Wasserverdunstungen unterbunden. Es können daher keine Kalkablagerungen im Bereich des Strahlerzeugungsquerschnitts entstehen, so daß über einen langen Gebrauchszeitraum gleichbleibende Brausestrahlen in dem Düsenkanal erzeugt werden können. Weitere Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 10 angegeben.The invention is based on the object of designing the water jet nozzles in the shower head in such a way that the lime deposits from the shower water occur essentially harmlessly outside the cross-section of the jet generation.
This object is achieved in that the water jet nozzles each have a nozzle channel, the jet generation cross section of which is formed upstream of the outlet opening and the remaining channel section is expanded with the outlet opening in the direction of flow. These measures ensure that when the shower is not in use, the water evaporates in the area of the enlarged outlet openings and the limescale deposits that occur in this area are thus harmless in this area. This prevents water evaporation in the area of the jet generation cross-section further upstream. There can therefore be no limescale deposits in the area of the jet generation cross section, so that constant shower jets can be generated in the nozzle channel over a long period of use. Further refinements of the invention are specified in claims 2 to 10.

Der Einfachheit halber sind bei den Ausführungsbeispielen in der Zeichnung gleiche oder entsprechende Elemente mit jeweils gleichen Bezugszeichen versehen.For the sake of simplicity, the same or corresponding elements are provided with the same reference numerals in the exemplary embodiments in the drawing.

Die in den Figuren 1 bis 5 gezeigten Düsenkanäle 1 sind jeweils auf einem oder mehreren Kreisbögen eines Brausebodens 2 angeordnet und werden beim Brausebetrieb vom zuströmenden Wasser in Richtung des Pfeils 13 beaufschlagt. Der in dem Düsenkanal 1 erzeugte Brausestrahl wird dabei vom Strahlerzeugungsquerschnitt 10 bestimmt. Der Strahlerzeugungsquerschnitt 10 weist in der Regel eine Kreisfläche auf, deren Durchmesser etwa 1 bis 2 mm beträgt.The nozzle channels 1 shown in FIGS. 1 to 5 are each arranged on one or more arcs of a shower base 2 and are acted upon by the inflowing water in the direction of arrow 13 during shower operation. The shower jet generated in the nozzle channel 1 is determined by the jet generation cross section 10. The beam generation cross section 10 generally has a circular area, the diameter of which is approximately 1 to 2 mm.

Bei dem in Figur 1 gezeigten Düsenkanal 1 ist der Strahlerzeugungsquerschnitt 10 im Bereich der oberen Kante des Brausebodens 2 angeordnet. In Fließrichtung, hinter dem Strahlerzeugungsquerschnitt 10, ist eine Kanalstrecke 11 zunächst beschleunigt erweitert ausgebildet, um dann im Endbereich verlangsamt nahezu keineIn the nozzle duct 1 shown in FIG. 1, the jet generation cross section 10 is arranged in the region of the upper edge of the shower base 2. In the direction of flow, behind the jet generation cross section 10, a channel section 11 is initially designed to be expanded in an accelerated manner, and then almost none in the end region is slowed down

Erweiterung mehr zu erfahren. Der im Strahlerzeugungsquerschnitt 10 entstehende Brausestrahl ist in gestrichelten Linien im Düsenkanal 1 angedeutet. Die während des Stillstands des Brausebetriebs auftretenden Brausewasserverdunstun gen im Bereich der Wasseraustrittsöffnung 12 können sich somit unschädlich in dem balligen Ringraum der Kanalstrecke 11 ablagern, ohne daß der austretende Brausestrahl hiervon behindert wird.Extension to learn more. The shower jet formed in the jet generation cross section 10 is indicated in dashed lines in the nozzle channel 1. The occurring during the standstill of the shower operation Brausewasserverdunstun conditions in the area of the water outlet opening 12 can thus be deposited harmlessly in the spherical annular space of the channel section 11 without the emerging shower jet being hindered thereby.

Der in Figur 2 gezeigte Düsenkanal 1 ist sprungartig hinter dem Strahlerzeugungsquerschnitt 10 erweitert.The nozzle channel 1 shown in FIG. 2 is expanded abruptly behind the jet generation cross section 10.

Der in Figur 3 gezeigte Düsenkanal 1 weist dagegen stromabwärts hinter dem Strahlerzeugungsquerschnitt 10 eine stetige Erweiterung bis zur Austrittsöffnung 12 auf.The nozzle duct 1 shown in FIG. 3, on the other hand, has a continuous widening downstream of the jet generation cross section 10 up to the outlet opening 12.

In Figur 4 ist ein Düsenkanal 1 gezeigt, dessen Strahlerzeugungsquerschnitt 10 mit der Oberkante des Brausebodens 2 zusammenfällt. Hierdurch kann der gesamte Düsenkanal 1 als konischer Durchbruch ausgebildet sein.FIG. 4 shows a nozzle duct 1, the jet generation cross section 10 of which coincides with the upper edge of the shower base 2. As a result, the entire nozzle channel 1 can be designed as a conical opening.

In Figur 5 ist schließlich ein aus einem schlauchartigen, elastischen Material hergestellter Düsenkanal 1 gezeigt, der in einen als Tragkörper ausgebildeten Brauseboden 2 eingeknöpft werden kann. Der schlauchartige Teil des Düsenkanals 1 weist dabei eine entsprechend Figur 1 gewölbte Erweiterung in Fließrichtung des Wassers auf. Der schlauchartige Teil des Düsenkanals 1 kragt mit einem Endbereich 14 an der stromabwärts gelegenen Seite des Brausebodens vor, so daß bei sehr starken Kalkabscheidungen im Bereich der Austrittsöffnung 12 diese sehr leicht entfernt werden können durch einfaches Verwalken der Endbereiche 14 von Hand. Zur sicheren Halterung des schlauchartigen Düsenkanals 1 imFinally, FIG. 5 shows a nozzle channel 1 made of a hose-like, elastic material, which can be buttoned into a shower base 2 designed as a supporting body. The hose-like part of the nozzle channel 1 has an arched widening in accordance with FIG. The hose-like part of the nozzle channel 1 projects with an end region 14 on the downstream side of the shower base, so that in the case of very strong limescale deposits in the region of the outlet opening 12 these can be removed very easily by simply rolling the end regions 14 by hand. To securely hold the hose-like nozzle channel 1 in

Brauseboden 2 ist dieser stromaufwärts mit einem Bund 15 in der Stecklage gesichert. Anstatt besondere, in den Brauseboden 2 einknöpfbare Düsenkanäle 1, können auch direkt im Brauseboden 2 ausgebildete Düsenkanäle 1 vorgesehen sein, die an der stromabwärts gelegenen Seite jeweils von einem hervorstehenden, flexiblen Endstück oder Endbereich 14 umgeben sind. Diese Endstücke können unmittelbar am Brauseboden ausgebildet sein oder als separate Teile angeklebt oder anvulkanisiert sein.Shower base 2 is secured upstream with a collar 15 in the plug-in position. Instead of special nozzle channels 1 that can be buttoned into the shower base 2, nozzle channels 1 formed directly in the shower base 2 can also be provided, each of which is surrounded on the downstream side by a protruding, flexible end piece or end area 14. These end pieces can be formed directly on the shower base or glued or vulcanized as separate parts.

In Figur 6 ist schließlich eine Handbrause 3 zum Teil gezeigt, bei der ein Brauseboden vorgesehen ist, der aus einem oberen Bodenteil 21 und einem unteren Bodenteil 22 gebildet ist. Hierdurch können in dem Bodenteil 21 die Strahlerzeugungsquerschnitte 10 und im Bodenteil 22 die erweiterten Kanalstrecken 11 als Durchgangsbohrungen ausgebildet sein.
Die beiden Bodenteile 21,22 sind mit geringem Abstand, beispielsweise 1 mm, zueinander in dem Gehäuse der Handbrause 3 angeordnet, so daß ein Spalt 23 erzeugt wird. Konzentrisch im oberen Bodenteil 21 ist außerdem ein Kanal 24 ausgebildet, der über ein auf den Wasserdruck ansprechendes Ventil 25 mit dem Innenraum der Handbrause 3 verbunden ist. Die vorstehend angegebene Handbrause 3 hat folgende Wirkungsweise:
Beim Brausebetrieb wird das Druckwasser über den Handgriff in den Brausekopf der Handbrause 3 gedrückt, wobei der statische Druck in den Strahlerzeugungsquerschnitten 10 in Strömungsgeschwindigkeit umgewandelt wird, so daß einzelne Brausestrahlen berührungsfrei durch den Spalt 23 und den Kanalstrecken 11 ins Freie gelangen. Durch das Druckwasser in der Handbrause 3 wird das Ventil 25 in Schließstellung gedrückt, so daß über den Kanal 24 kein Wasser in den Spalt 23 gelangen kann.Finally, FIG. 6 shows a hand shower 3 in part, in which a shower base is provided which is formed from an upper base part 21 and a lower base part 22. As a result, the beam generation cross sections 10 and in the base part 22 the expanded channel sections 11 can be formed as through bores in the base part 21.
The two base parts 21, 22 are arranged at a short distance, for example 1 mm, from one another in the housing of the hand shower 3, so that a gap 23 is created. A channel 24 is also formed concentrically in the upper base part 21 and is connected to the interior of the hand shower 3 via a valve 25 which responds to the water pressure. The hand shower 3 specified above has the following mode of operation:
During shower operation, the pressurized water is pressed into the shower head of the hand shower 3 via the handle, the static pressure in the jet generation cross sections 10 being converted into flow velocity, so that individual shower jets reach the outside without contact through the gap 23 and the channel sections 11. The valve 25 is pressed into the closed position by the pressurized water in the hand shower 3, so that no water can get into the gap 23 via the channel 24.

Wird nun die Wasserzufuhr abgesperrt, so sinkt der Druck im Brausekopf der Handbrause 3 und das Ventil 25 öffnet sich bei einem Druck von beispielsweise 0,2 bar. Nunmehr kann Wasser über den Kanal 24 in den Spalt 23 strömen und diesen auffüllen, wobei der Flüssigkeitsdruck in der Handbrause 3 auf Atmosphärendruck abgefallen ist, so daß aus den Strahlerzeugungsquerschnitten 10 keine Brausestrahlen mehr austreten. Der mit dem Restwasser gefüllte Spalt 23 bildet einen Wasserfilm, der somit die stromaufwärts gelegenen feinen Strahlerzeugungsquerschnitte 10 im Düsenkanal 1 gegen Verkalkung schütztIf the water supply is now shut off, the pressure in the shower head of the hand shower 3 drops and the valve 25 opens at a pressure of, for example, 0.2 bar. Water can now flow through the channel 24 into the gap 23 and fill it up, the liquid pressure in the hand shower 3 having dropped to atmospheric pressure, so that no more shower jets emerge from the jet generation cross sections 10. The gap 23 filled with the residual water forms a water film, which thus protects the upstream fine jet generation cross sections 10 in the nozzle channel 1 against calcification
