Description

Die Erfindung betrifft einen Brausekopf mit einem Wasserdurchtrittsöffnungen aufweisenden Bodenteil aus einem elastischen Material, wobei die Wasserdurchtrittsöffnungen an der Unterseite des Brausekopfes austreten und über die Unterseite überstehen.The invention relates to a shower head with a water passage openings Bottom part made of an elastic material, the water passage openings emerge from the underside of the shower head and protrude beyond the underside.

Brauseköpfe sind als Teil einer Brause in fast jedem Haushalt zu finden und seit Jahrzehnten bekannt. Probleme ergeben sich bei Brauseköpfen insbesondere bei hartem bis sehr hartem Leitungswasser, aus dem sich sehr rasch und massiv Kalkablagerungen ausscheiden. Die Kalkablagerungen setzen die Wasserdurchtrittsöffnungen zu und beeinträchtigen wesentlich die Funktion des Brausekopfes.Shower heads can be found in almost every household as part of a shower head and have been for decades known. Problems arise with shower heads, especially with hard ones to very hard tap water, from which limescale accumulates very quickly and massively retire. The limescale clog the water passage openings and significantly impair the function of the shower head.

Um die an sich nicht zu verhindernden Kalkablagerungen zu beseitigen, sind bereits verschiedene Vorschläge gemacht worden.In order to remove the limescale deposits, which cannot be prevented per se, are already various suggestions have been made.

Aus der EP - A- 0 443 538 ist bereits ein Brausekopf der eingangs beschriebenen Art bekannt, wobei am Bodenteil angeformte Zapfen vorgesehen sind, durch die die Wasserdurchtrittsöffnungen hindurchgeführt sind und die über die Unterseite des Brausekopfes überstehen. Durch ein manuelles "Rubbeln" über die elastisch verformbaren Enden der Zapfen soll eine Entfernung der Kalkverkrustungen möglich sein.EP - A - 0 443 538 already discloses a shower head of the type described in the introduction known, with molded-on pins are provided through which the Water passage openings are passed through and over the bottom of the Survive shower head. By manually "rubbing" over the elastically deformable Removal of lime scale should be possible at the ends of the cones.

Auf einem ähnlichen Prinzip beruht der aus der EP - A - 0 435 031 bekannte Brausekopf, an dessen Bodenteil schlauchartige Austrittsöffnungen aus einem Werkstoff mit einer Materialhärte von 20 bis 100 Shore vorgesehen sind. Durch manuelles "Rubbeln" an den schlauchartigen Austrittsöffnungen soll in diesen abgelagerter Kalk abgelöst werden.The shower head known from EP-A-0 435 031 is based on a similar principle, at the bottom part with hose-like outlet openings made of a material a material hardness of 20 to 100 Shore are provided. By manual "scratching" Lime deposited in the hose-like outlet openings is to be detached into this become.

Sowohl in der EP - A - 0 443 538 als auch in der EP - A - 0 435 031 stehen also die Wasserdurchtrittsöffnungen über zapfen- oder schlauchartige Verlängerungen über die Unterseite des Brausekopfes über. Das Problem bei den bekannten zapfen- oder schlauchartigen Verlängerungen besteht darin, daß es beim manuellen "Rubbeln", insbesondere aufgrund der Dünnwandigkeit der Verlängerungen, zum Abknicken, Einreißen oder gänzlichem Abreißen der Verlängerungen kommen kann. Hierdurch kann nicht nur die Funktion des Brausekopfes, sondern auch die Möglichkeit der Beseitigung der Kalkablagerungen wesentlich beeinträchtigt werden. Both EP - A - 0 443 538 and EP - A - 0 435 031 contain the Water through openings via spigot or hose-like extensions the bottom of the shower head over. The problem with the well-known cones or hose-like extensions is that when manually "rubbing", especially due to the thin walls of the extensions, for kinking, Tearing or complete tearing of the extensions can occur. Hereby can not only the function of the shower head, but also the possibility of Removal of limescale will be significantly affected.

Die Erfindung geht nun einen neuen Weg. Erfindungsgemäß ist bei dem eingangs beschriebenen Brausekopf vorgesehen, daß das Bodenteil einen etwa ringförmig ausgebildeten Vorsprung aufweist, der über die Unterseite des Brausekopfes übersteht, und daß die Wasserdurchtrittsöffnungen über die Länge des Vorsprungs verteilt sind. Bei der Erfindung wird also nach wie vor die Möglichkeit des manuellen "Rubbelns" ausgenutzt, um Kalkablagerungen in den Wasserdurchtrittsöffnungen zu beseitigen. Allerdings besteht bei dem erfindungsgemäßen Brausekopf mit dem wenigstens ein Ringsegment, vorzugsweise aber die Form eines geschlossenen Ringes aufweisenden Vorsprung nicht mehr die Gefahr der Beschädigung, die bei den zuvor erwähnten Verlängerungen gegeben ist. Durch den umlaufenden Vorsprung sind die Wasserdurchtrittsöffnungen derart verstärkt, daß die Gefahr der Beschädigung des Bodenteils beim "Rubbeln" nicht mehr besteht. Da der Vorsprung aber aus dem gleichen elastischen Material besteht wie das Bodenteil, läßt sich der ringförmige Vorsprung ohne weiteres durch manuelles "Rubbeln" elastisch verformen, wodurch die Kalkpartikel in den Wasserdurchtrittsöffnungen abgelöst und dann aus diesen herausfallen oder herausgespült werden.The invention now goes a new way. According to the invention is described in the beginning Shower head provided that the bottom part has an approximately annular design Has projection that protrudes over the underside of the shower head, and that the water passage openings are distributed over the length of the projection. With the invention, the possibility of manual "rubbing" is still exploited to remove limescale deposits in the water passage openings. However, in the shower head according to the invention there is at least one Ring segment, but preferably having the shape of a closed ring Head start no longer the risk of damage occurring with the aforementioned Extensions are given. Due to the all-round projection, the water passage openings are so amplified that the risk of damage to the bottom part no longer exists when "scratching". Because the projection is made of the same elastic Material is like the bottom part, the annular projection can be made without further deform by manual "rubbing" elastically, whereby the lime particles in detached from the water passage openings and then fall out of them or flushed out become.

In Fig. 1 ist ein erfindungsgemäßer Brausekopf 1 in Querschnittsansicht dargestellt. Der Brausekopf 1, dessen grundsätzlicher Aufbau an sich bekannt ist, weist eine Wasserzuführung 2 auf. Weiterhin ist der Brausekopf 1 mit einem Wasserdurchtrittsöffnungen 3 aufweisenden Bodenteil 4 versehen. Das Bodenteil 4 besteht aus elastischem Material, vorzugsweise mit einer Materialhärte von 20 bis 120 Shore. Die Wasserdurchtrittsöffnungen 3 treten an der Unterseite 5 des Brausekopfes 1 aus. Außerdem stehen die Wasserdurchtrittsöffnungen 3 zumindest bei der rechten Ausführungsform gemäß Fig. 1 über die Unterseite 5 des Brausekopfes 1 über. Bei der in der Fig. 1 dargestellten linken Ausrührungsform stehen demgegenüber die Wasserdurchtrittsöffnungen 3, wenn überhaupt, nur ganz geringfügig über die Unterseite 5 des Brausekopfes 1 über. Das Bodenteil 4 ist im Brausekopf 1 gehalten und steht mit der Wasserzuführung 2 in Verbindung.In Fig. 1 a shower head 1 according to the invention is shown in cross-sectional view. The shower head 1, the basic structure of which is known per se, has one Water supply 2 on. Furthermore, the shower head 1 with a water passage openings 3 having bottom part 4 provided. The bottom part 4 consists of elastic Material, preferably with a material hardness of 20 to 120 Shore. The water passage openings 3 emerge from the underside 5 of the shower head 1. Moreover are the water passage openings 3 at least in the right embodiment 1 on the underside 5 of the shower head 1. At the in the 1, left-hand embodiment, in contrast, are the water passage openings 3, if at all, only very slightly over the bottom 5 of the Shower head 1 over. The bottom part 4 is held in the shower head 1 and stands with the Water supply 2 in connection.

Wesentlich ist nun, daß das Bodenteil 4 wenigstens einen etwa ringförmig ausgebildeten Vorsprung 6 aufweist, der über die Unterseite 5 des Brausekopfes 1 übersteht, wobei die Wasserdurchtrittsöffnungen 3 über die Länge des Vorsprungs 6 verteilt angeordnet sind. Der Vorsprung 6 weist wenigstens ein Ringsegment auf, das sich zumindest über einen Teil der Unterseite 5 des Brausekopfes 1 umfangartig erstreckt. Vorzugsweise weist der Vorsprung 6 aber die Form eines geschlossenen Ringes auf, der umfangsmäßig an der Unterseite 5 des Brausekopfes 1 angeordnet ist. Im übrigen versteht es sich aber auch, daß der Vorsprung 6 die Form eines geöffneten Ringes haben kann.It is now essential that the bottom part 4 has at least one approximately ring-shaped Has projection 6 which protrudes over the underside 5 of the shower head 1, wherein the water passage openings 3 distributed over the length of the projection 6 are arranged. The projection 6 has at least one ring segment, which is extends at least over part of the underside 5 of the shower head 1. However, the projection 6 preferably has the shape of a closed ring, which is arranged circumferentially on the underside 5 of the shower head 1. Furthermore it is also understood that the projection 6 have the shape of an open ring can.

Der ringförmige Vorsprung 6, der an sich aus Vollmaterial besteht und lediglich an einigen Stellen von den Wasserdurchtrittsöffnungen 3 durchstoßen ist, kann aufgrund der Materialeigenschaften des Bodenteils 4 ohne weiteres manuell durch "Rubbeln" verformt werden, wobei sich auch die Wasserdurchtrittsöffnungen 3 in ihrer Form verändern, was zur Folge hat, daß sich darin abgelagerter Kalk löst und ausgetragen wird. Die Wasserdurchtrittsöffnungen 3 treten jeweils an der höchsten Stelle des Vorsprungs 6 aus, sind also zumindest in Umfangsrichtung von vergleichsweise viel elastischem Material des Bodenteils 4 umgeben, so daß ein Abbrechen bzw. eine Beschädigung des Vorsprungs 6 beim "Rubbeln" nicht zu befürchten ist.The annular projection 6, which consists of solid material and only some Places is penetrated by the water passage openings 3, can the material properties of the bottom part 4 easily manually by "rubbing" are deformed, the water passage openings 3 also changing in shape change, which has the result that lime deposited therein dissolves and is discharged becomes. The water passage openings 3 occur at the highest point of the projection 6, are at least in the circumferential direction of comparatively much elastic Surround the material of the bottom part 4, so that a break or damage the projection 6 when "rubbing" is not to be feared.

Um eine gute Wasserverteilung des Brausekopfes 1 zu gewährleisten, bietet es sich an, die Wasserdurchtrittsöffnungen 3 über den Umfang des Vorsprungs 6 gleichmäßig zu verteilen. Dabei ist festgestellt worden, daß es für ein gutes Strahlergebnis ausreichend ist, wenn die einzelnen Wasserdurchtrittsöffnungen 3 um einen Bogenwinkel von 6° beabstandet sind. Auf diese Weise erhält man also 60 Wasserdurchtrittsöffnungen 3, wobei aufgrund der erfindungsgemäßen Funktion sichergestellt ist, daß immer alle 60 Wasserdurchtrittsöffnungen 3 nach gelegentlichem "Rubbeln" durchströmt werden.In order to ensure a good water distribution of the shower head 1, it offers itself on, the water passage openings 3 evenly over the circumference of the projection 6 to distribute. It has been found that it is sufficient for a good blasting result is when the individual water passage openings 3 by an arc angle are spaced from 6 °. In this way you get 60 water openings 3, wherein the function of the invention ensures that always flows through all 60 water openings 3 after occasional "rubbing" become.

Wie insbesondere aus Fig. 2 erkennbar ist, ist nicht nur der Vorsprung 6 ringförmig ausgebildet, sondern auch das Bodenteil 4. Es ist also nicht unbedingt erforderlich, daß sich das Bodenteil 4 über die gesamte Fläche der Unterseite 5 des Brausekopfes 1 erstreckt. Durch das ringförmige Bodenteil 4 ist es also möglich, die eigentliche Brausefunktion in den Bereich des äußeren Umfanges des Brausekopfes 1 zu verlegen, während der mittige Bereich für mögliche andere Funktionen des Brausekopfes 1 zur Verfügung steht.As can be seen in particular from FIG. 2, not only the projection 6 is annular trained, but also the bottom part 4. So it is not absolutely necessary that the bottom part 4 over the entire surface of the underside 5 of the shower head 1 extends. The ring-shaped base part 4 makes it possible to perform the actual shower function to move in the area of the outer circumference of the shower head 1, while the central area for possible other functions of the shower head 1 for Available.

Wie insbesondere in den Fig. 1 bis 3 erkennbar ist, weist das Bodenteil 4 einen im Querschnitt etwa U-förmig ausgebildeten Bereich 7 auf, an den sich bei den Ausführungsformen der Fig. 1 (rechte Darstellung) sowie Fig. 2 und 3 der Vorsprung 6 anschließt. Durch die U-förmige Ausbildung des Bereichs 7 läßt sich das Bodenteil 4 in besonders einfacher Weise in einem im Gehäuse des Brausekopfes 1 vorgesehenen Ringkanal 8 halten, worauf weiter unten noch näher eingegangen wird. Außerdem läßt sich der Vorsprung 6 aufgrund des U-förmigen Bereichs 7 in den Brausekopf 1 hineindrücken, was das Ablösen von Kalk erleichtert. Es versteht sich, daß das Bodenteil 4 aber auch an sich als Ringscheibe ausgebildet sein kann, an die sich der Vorsprung 6 nach unten hin anschließt. Statt einer seitlichen Klemmung über einen U-förmigen Bereich ist das Bodenteil 4 dann in entsprechender Weise im Gehäuse des Brausekopfes 1 zu halten bzw. zu klemmen. Wichtig ist, daß der Vorsprung 6 nicht nur hin- und herbewegbar, sondern auch in den Brausekopf 1 hineindrückbar ist.As can be seen in particular in FIGS. 1 to 3, the base part 4 has a Cross-section approximately U-shaped area 7, to which in the embodiments 1 (right illustration) and FIGS. 2 and 3 of the projection 6 connects. Due to the U-shaped design of the area 7, the bottom part 4 can be formed in provided in a particularly simple manner in a in the housing of the shower head 1 Hold ring channel 8, which will be discussed in more detail below. Moreover can the projection 6 due to the U-shaped region 7 in the shower head 1st press in, which makes it easier to remove limescale. It is understood that the bottom part 4 but can also be designed as an annular disc to which the Projection 6 connects downwards. Instead of a side clamping over one The bottom part 4 is then in a corresponding manner in the housing in a U-shaped region to hold or clamp the shower head 1. It is important that the projection 6 not only movable back and forth, but also pushed into the shower head 1 is.

Die Wasserdurchtrittsöffnungen 3 weisen einen sich in Durchflußrichtung verengenden Abschnitt 9 auf. Dieser sich verengende Abschnitt 9 wirkt in Art einer Venturi-Düse, führt also zur Beschleunigung des Wassers. Der Vorteil dieses sich verengenden Abschnitts 9 liegt darin, daß auch bei einer geringen Wassermenge ein recht kräftiger Wasserstrahl erzeugt werden kann. Der sich verengende Abschnitt 9 schließt sich unmittelbar an den U-förmigen Bereich 7 an. An den sich verengenden Abschnitt 9 schließt sich ein Austrittsabschnitt 10 an. In seinem Endbereich 11 ist der Austrittsabschnitt 10 entsprechend der gewünschten Wasseraustrittsrichtung angeschrägt. Dabei zeigt ein Vergleich der Fig. 3, 4 und 5, daß der Austrittsabschnitt 10 in seinem Endbereich 11 bei unterschiedlichen Wasserdurchtrittsöffnungen 3 auch unterschiedlich ausgebildet sein kann.The water passage openings 3 have a narrowing in the flow direction Section 9 on. This narrowing section 9 acts like a Venturi nozzle, thus leads to the acceleration of the water. The advantage of this narrowing Section 9 is that even with a small amount of water a right powerful water jet can be generated. The narrowing section 9 connects directly to the U-shaped area 7. On the narrowing Section 9 is followed by an outlet section 10. In its end region 11 is the Exit section 10 beveled according to the desired water outlet direction. A comparison of FIGS. 3, 4 and 5 shows that the outlet section 10 in its end region 11 also different with different water passage openings 3 can be trained.

Vorzugsweise ist, um ein gutes Strahlbild des Brausekopfes 1 zu erhalten, vorgesehen, daß einander benachbarte Wasserdurchtrittsöffnungen 3 unterschiedliche Wasserstrahlrichtungen aufweisen. Dies wird über entsprechende Anschrägungen 12 im Endbereich 11 der jeweiligen Wasserdurchtrittsöffnungen 3 erreicht. Bei Versuchen ist festgestellt worden, daß gute Strahlergebnisse erreicht werden, wenn die Wasserstrahlrichtung der einzelnen Wasserdurchtrittsöffnungen 3 zwischen 0 und 16° liegt, wobei in einer besonders bevorzugten Ausrührungsform ein sich periodisch wiederholendes Strahlbild mit Wasserstrahlrichtungen der einzelnen Wasserdurchtrittsöffnungen 3 von 8°, 5°, 8°, 5°, 8° und 2° vorgesehen ist (vgl. Fig. 6). Bei dem erwähnten Bogenwinkel von 6° ist dieses Strahlbild zehnfach im Vorsprung 6 vorgesehen, so daß dreißig Wasserdurchtrittsöffnungen 3 mit einer Neigung von 8° gegenüber der Senkrechten, zwanzig Wasserdurchtrittsöffnungen 3 mit einer Neigung von 5° und zehn Wasserdurchtrittsöffnungen 3 mit einer Neigung von 2° vorgesehen sind. Im dargestellten Ausführungsbeispiel weist der in Fig. 3 dargestellte Endbereich 11 eine Anschrägung 12 mit einem Winkel von 16° auf, so daß sich eine Wasserstrahlrichtung von 8° ergibt. In Fig. 4 weist die Anschrägung 12 im Endbereich 11 einen Winkel von 10° auf, so daß sich hier eine Wasserstrahlrichtung von 5° ergibt. Schließlich ist bei der in Fig. 5 dargestellten Ausführungsform die Anschrägung 12 unter einem Winkel von 4° gegenüber der Senkrechten geneigt, so daß sich eine Wasserstrahlrichtung von 2° ergibt. Der sich verengende Abschnitt 9 ist bei jeder einzelnen Wasserdurchtrittsöffnung 3 gleich. In Abhängigkeit von der gewünschten Wasserstrahlrichtung ist der Austrittsabschnitt 10 bei den einzelnen Wasserdurchtrittsöffnungen 3 unterschiedlich ausgebildet, der Endbereich 11 also länger oder kürzer.Preferably, in order to obtain a good spray pattern of the shower head 1, that adjacent water passage openings 3 different water jet directions exhibit. This is indicated by corresponding bevels 12 in End region 11 of the respective water passage openings 3 reached. When trying it has been found that good jet results are achieved when the water jet direction of the individual water passage openings 3 is between 0 and 16 °, in a particularly preferred embodiment a periodically repeating one Jet pattern with water jet directions of the individual water passage openings 3 of 8 °, 5 °, 8 °, 5 °, 8 ° and 2 ° is provided (see FIG. 6). With the mentioned Arc angle of 6 ° this beam pattern is provided ten times in the projection 6, so that thirty water passage openings 3 with an inclination of 8 ° relative to the Vertical, twenty water passage openings 3 with an inclination of 5 ° and ten water passage openings 3 are provided with an inclination of 2 °. in the The embodiment shown in FIG. 3 has an end region 11 Bevel 12 at an angle of 16 ° so that there is a water jet direction of 8 ° results. 4, the bevel 12 has an angle in the end region 11 from 10 ° to a water jet direction of 5 °. Finally is in the embodiment shown in Fig. 5, the bevel 12 under a Angle of 4 ° inclined from the vertical so that there is a water jet direction of 2 ° results. The narrowing section 9 is at each individual water passage opening 3 equal. Depending on the desired water jet direction is the outlet section 10 at the individual water passage openings 3 differently designed, the end region 11 longer or shorter.

Aufgrund der unterschiedlichen Ausbildung der Austrittsabschnitte 10 bzw. der einzelnen Endbereiche 11 können sich unterschiedliche Strömungswiderstände ergeben. Die Wasserdurchtrittsöffnungen 3 sind jedoch derart ausgebildet, daß sich unabhängig von der Wasserstrahlrichtung eine gleiche Durchflußrate ergibt. Dies ist dadurch realisiert, daß die untere Fläche der Wasserdurchtrittsöffnungen 3 im Bereich des Austritts den gewünschten Erfordernissen entsprechend unter einem kleinen Winkel α von 0 bis 1° angeschrägt ist. Hierdurch ergibt sich im Bereich der Anschrägung 12 anschließend an den Endbereich 11 ein Überstand 13, durch den sich die Wasserdurchtrittsöffnung 3 verengt.Due to the different design of the outlet sections 10 or the individual End regions 11 can result in different flow resistances. However, the water passage openings 3 are designed such that they are independent gives an equal flow rate from the water jet direction. This is because of it realizes that the lower surface of the water passage openings 3 in the region of the outlet according to the desired requirements at a small angle α is chamfered from 0 to 1 °. This results in the area of the bevel 12 after the end region 11, a protrusion 13 through which the water passage opening 3 narrowed.

Wie sich insbesondere aus den Fig. 8 und 9 ergibt, ist innenseitig und/oder außenseitig des Vorsprungs 6 und/oder des Bodenteils 4 wenigstens eine Ausbuchtung 14 vorgesehen. Die Ausbuchtungen 14 haben nicht nur einen ästhetischen Effekt, sie vermitteln nämlich beim Abstreifen von Kalk den Eindruck des "Rubbelns", sondern dienen auch dazu, ein Verschieben des ringförmigen Bodenteils 4 innerhalb des Brausekopfes 1 zu vermeiden. Außerdem ergibt sich aus den Fig. 8 und 9, daß die Wasserdurchtrittsöffnungen 3 zumindest an ihrem austrittsseitigen Ende eine Rechteckform aufweisen.As can be seen in particular from FIGS. 8 and 9, is on the inside and / or outside of the projection 6 and / or of the base part 4 at least one bulge 14 intended. The bulges 14 not only have an aesthetic effect, they give the impression of "rubbing" when stripping lime, but also serve to move the annular bottom part 4 within the Avoid shower head 1. It also follows from FIGS. 8 and 9 that the Water passage openings 3 at least at their outlet end Have a rectangular shape.
