Sanitäre Brause Sanitary shower head
Die vorliegende Erfindung betrifft eine sanitäre Brause zur Bereitstellung von Wasser mit einer Auslasseinrichtung. The present invention relates to a sanitary shower head for providing water with an outlet device.
Sanitäre Brausen sind fluidisch mit einer Sanitärarmatur verbindbar und dienen beispielsweise an Spülbecken, Waschbecken, Bidets, Badewannen und/oder Duschen der bedarfsgerechten Bereitstellung von Wasser. Das Wasser strömt aus einer Auslasseinrichtung, die ausgebildet ist, einen Wasserstrahl zu formen. Sanitary showers can be fluidly connected to a sanitary fitting and are used, for example, to provide water as needed in sinks, washbasins, bidets, bathtubs and/or showers. The water flows from an outlet device which is designed to form a water jet.
Ein typisches Problem im Hinblick auf sanitäre Brausen besteht darin, dass sich in der Auslasseinrichtung Kalkablagerungen, insbesondere bei hartem Versorgungswasser, oder andere Ablagerungen im Laufe der Zeit ansammeln. Dies kann zu einem reduzierten Durchfluss des Wassers und einem verschlechterten Strahlbild führen. Darüber hinaus können solche Ablagerungen in der Auslasseinrichtung letztlich auch zu einer Beschädigung der Brause führen. A typical problem with sanitary showerheads is that limescale deposits, especially with hard supply water, or other deposits accumulate in the outlet device over time. This can lead to reduced water flow and a deteriorated spray pattern. In addition, such deposits in the outlet device can ultimately lead to damage to the shower.
Um die vorgenannten Folgen abzuwenden, werden aus dem Stand der Technik bekannte sanitäre Brausen üblicherweise manuell gereinigt, beispielsweise mechanisch durch leichtes Drücken und Reiben der Auslasseinrichtung und/oder chemisch durch Aufträgen und Einwirken von geeigneten Reinigungsmitteln, zum Beispiel Zitronensäure, auf die Auslasseinrichtung. Die manuelle Reinigung der Auslasseinrichtung ist allerdings relativ aufwändig. In order to avert the aforementioned consequences, sanitary shower heads known from the prior art are usually cleaned manually, for example mechanically by gently pressing and rubbing the outlet device and/or chemically by applying and acting on the outlet device with suitable cleaning agents, for example citric acid. However, manually cleaning the outlet device is relatively time-consuming.
Ein weiteres typisches Problem sanitärer Brausen ist das Nachlaufen von Wasser nachdem der Wasserfluss durch Schließen eines entsprechenden Ventils seitens des Nutzers geschlossen worden ist. Nachlaufen von Wasser bedeutet, dass nach Beendigung der Benutzung der sanitären Brause noch eine kleine Wassermenge aus der sanitären Brause herausfließt oder heraustropft, obwohl der Nutzer das Ventil bereits geschlossen hat. Das Nachlaufen von Wasser kann wenige Sekunden oder Minuten bis hin zu einigen Stunden nach Beendigung der Benutzung der sanitären Brause stattfinden. Dies ist insbesondere dann unerwünscht, wenn das nachlaufende Wasser aus der sanitären Brause auf bereits getrocknete Oberflächen des Spülbeckens, des Waschbeckens, des Bidets, der Badewanne und/oder der Dusche trifft. So können Wasserflecken oder andere Spuren auf diesen Oberflächen entstehen. Ein Nachlaufen des Wassers aus der sanitären Brause ist auch dann unerwünscht, wenn das Wasser auf den Nutzer selbst tropft nachdem er sich bereits abgetrocknet hat. In jedem Fall bedeutet ein Nachlaufen von Wasser aus der sanitären Brause, dass das Spülbecken, das Waschbecken, das Bidet, die Badewanne und/oder die Dusche zumindest teilweise erneut getrocknet werden muss oder dass der Nutzer sich selbst zumindest teilweise erneut abtrocknen muss. Dies wird oftmals als störend empfunden. Another typical problem with sanitary showers is the water running after the water flow has been closed by the user by closing a corresponding valve. Water overflow means that after you have finished using the sanitary shower, a small amount of water still flows or drips out of the sanitary shower, even though the user has already closed the valve. Water may continue to run after a few seconds or minutes to a few hours after you stop using the device sanitary shower takes place. This is particularly undesirable when the water running from the sanitary shower hits already dried surfaces of the sink, washbasin, bidet, bathtub and/or shower. This can result in water stains or other marks on these surfaces. It is also undesirable for the water to continue running from the sanitary shower if the water drips onto the user after they have already dried themselves. In any case, running water from the sanitary shower means that the sink, washbasin, bidet, bathtub and/or shower must be at least partially dried again or that the user must at least partially dry themselves again. This is often perceived as disturbing.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die voranstehend insgesamt erläuterte Problematik zumindest teilweise zu lösen und insbesondere eine sanitäre Brause anzugeben, die deren Reinigung erleichtert und die das Nachlaufen von Wasser verhindert oder wenigstens vermindert. The present invention is therefore based on the object of at least partially solving the problem explained above and, in particular, of providing a sanitary shower head which facilitates its cleaning and which prevents or at least reduces the running of water.
Die hier zugrundeliegende Aufgabe wird gelöst durch eine sanitäre Brause mit den Merkmalen des Patentanspruchs 1. Vorteilhafte Weiterbildungen ergeben sich jeweils aus den Unteransprüchen. The underlying task here is solved by a sanitary shower with the features of patent claim 1. Advantageous further developments result from the subclaims.
Es wird eine sanitäre Brause zur Bereitstellung von Wasser mit einer Auslasseinrichtung vorgeschlagen, wobei die Auslasseinrichtung eine Strahlformeinheit und eine relativ zu der Strahlformeinheit bewegliche Sperreinheit umfasst, wobei die Sperreinheit dazu eingerichtet ist, wenn der durch zuströmendes Wasser entstehende Druck bzw. Innendruck in der Auslasseinrichtung einen definierbaren Druckwert bzw. Druck bzw. Wert übersteigt, die Strahlformeinheit zu öffnen, und ansonsten die Strahlformeinheit zu sperren. Mit anderen Worten dient die Sperreinheit zum Öffnen und Sperren der Strahlformeinheit, das heißt zum Öffnen und Sperren des Wasserauslasses, in Abhängigkeit von dem in der Auslasseinrichtung herrschenden, durch das zuströmende Wasser entstehenden Innendruck. Die Auslasseinrichtung bildet einen Raum, der mit dem zuströmenden Wasser füllbar ist. Wenn dieser Raum vollständig mit Wasser befüllt ist und weiteres Wasser zuströmt, erhöht sich nach und nach der Druck in der Auslasseinrichtung. In einem druckbehafteten Zustand der erfindungsgemäßen sanitären Brause, genauer gesagt wenn der Innendruck den definierbaren Wert übersteigt, öffnet sich die Strahlformeinheit und fließt daraufhin Wasser aus der Auslasseinrichtung. In einem drucklosen Zustand der erfindungsgemäßen sanitären Brause, genauer gesagt wenn der Innendruck den definierbaren Wert unterschreitet oder nicht übersteigt, schließt bzw. sperrt sich die Strahlformeinheit und fließt kein Wasser aus der Auslasseinrichtung. Auf diese Weise ist ein Nachlaufen von Wasser nachdem der Wasserfluss durch Schließen eines entsprechenden Ventils seitens des Nutzers geschlossen worden ist, verhindert. A sanitary shower for providing water with an outlet device is proposed, the outlet device comprising a jet shaping unit and a locking unit movable relative to the jet shaping unit, the locking unit being set up when the pressure or internal pressure in the outlet device resulting from inflowing water exceeds a definable pressure value or pressure or value, to open the jet shaping unit, and otherwise to lock the jet shaping unit. In other words, the locking unit serves to open and lock the jet shaping unit, that is to say to open and lock the water outlet, depending on the pressure prevailing in the outlet device incoming water creates internal pressure. The outlet device forms a space that can be filled with the inflowing water. When this space is completely filled with water and more water flows in, the pressure in the outlet device gradually increases. In a pressurized state of the sanitary shower according to the invention, more precisely when the internal pressure exceeds the definable value, the jet shaping unit opens and water then flows out of the outlet device. In a depressurized state of the sanitary shower according to the invention, more precisely when the internal pressure falls below or does not exceed the definable value, the jet forming unit closes or blocks itself and no water flows out of the outlet device. In this way, water running after the water flow has been closed by the user by closing a corresponding valve is prevented.
Die erfindungsgemäße sanitäre Brause kann als Handbrause ausgestaltet sein, um eine räumlich zielgerichtete Bereitstellung des Wassers zu ermöglichen, oder als Kopfbrause ausgestaltet sein, um eine für den Nutzer besonders bequeme Bereitstellung des Wassers zu ermöglichen. Die Auslasseinrichtung ist eine Wasserauslasseinrichtung und dient zum Auslassen von Wasser aus der sanitären Brause. The sanitary shower according to the invention can be designed as a hand shower in order to enable a spatially targeted provision of the water, or can be designed as an overhead shower in order to enable the water to be provided in a particularly convenient manner for the user. The outlet device is a water outlet device and is used to drain water from the sanitary shower.
Durch jede der Relativbewegungen zwischen der Strahlformeinheit und der Sperreinheit wird die Strahlformeinheit mechanisch und ohne manuelles Zutun gereinigt. Denn sich etwaig angesammelte Kalkablagerungen oder sonstige Ablagerungen innerhalb der Strahlformeinheit der Auslasseinrichtung gelangen durch die Relativbewegung in Berührung mit der Sperreinheit und werden dadurch zerstoßen und abgetragen. Die so abgetragenen Ablagerungen werden durch das fließende Wasser unmittelbar aus der sanitären Brause herausgetragen. Dies passiert automatisch im Sinne von allein durch den durch Wasserdruck bewegbaren Mechanismus in der erfindungsgemäßen sanitären Brause. Eine manuelle Reinigung der sanitären Brause von solchen Ablagerungen kann somit entfallen. Dies erleichtert die Reinigung der erfindungsgemäßen sanitären Brause, insbesondere wenn die sanitäre Brause an nur schwer zugänglichen Stellen angebracht ist. Das Sperren der Strahlformeinheit, wenn der Innendruck in der Auslasseinrichtung den definierbaren Wert nicht übersteigt, sondern vielmehr unter dem definierbaren Wert liegt, verhindert außerdem das Nachlaufen von Wasser. Through each of the relative movements between the jet shaping unit and the locking unit, the jet shaping unit is cleaned mechanically and without manual intervention. Any accumulated limescale or other deposits within the jet forming unit of the outlet device come into contact with the locking unit due to the relative movement and are thereby crushed and removed. The deposits removed in this way are carried away directly from the sanitary shower by the flowing water. This happens automatically in the sense of just the mechanism in the sanitary shower according to the invention that can be moved by water pressure. This eliminates the need for manual cleaning of the sanitary shower head to remove such deposits. This makes it easier to clean the sanitary shower head according to the invention, especially if the sanitary shower head is in places that are difficult to access is appropriate. Blocking the jet shaping unit when the internal pressure in the outlet device does not exceed the definable value, but rather is below the definable value, also prevents water from running over.
Nach einer vorteilhaften Ausgestaltung der erfindungsgemäßen sanitären Brause umfasst die Auslasseinrichtung eine Federeinheit zur federnden Lagerung der Sperreinheit. Die Federeinheit umfasst zumindest eine Feder, insbesondere Druckfeder. Die Sperreinheit und die Federeinheit sind fest miteinander verbunden. Die Federeinheit spannt die Sperreinheit durch ihre Federkraft in Richtung der Strahlformeinheit vor, das heißt drückt die Sperreinheit durch diese Federkraft in Richtung der Strahlformeinheit. Der Innendruck in der Auslasseinrichtung wirkt gegen die Federkraft der Federeinheit. Bei steigendem Innendruck durch weiter zuströmendes Wasser wird zunächst ein Kräftegleichgewicht erreicht zwischen der durch den Innendruck erzeugten Kraft des zuströmenden Wassers und der Federkraft der Federeinheit und wird schließlich der Innendruck die Federkraft der Federeinheit übersteigen, wodurch die Sperreinheit zurückgeschoben wird, sodass sich die Stahlformeinheit öffnet und Wasser aus der Strahlformeinheit fließen kann. Durch diese Ausgestaltung ist die Strahlformeinheit in ihrer Voreinstellung gesperrt. So ist das Nachlaufen von Wasser verhindert oder wenigstens vermindert. According to an advantageous embodiment of the sanitary shower according to the invention, the outlet device comprises a spring unit for resilient mounting of the locking unit. The spring unit comprises at least one spring, in particular a compression spring. The locking unit and the spring unit are firmly connected to each other. The spring unit biases the locking unit in the direction of the jet shaping unit by its spring force, that is, the locking unit presses in the direction of the jet shaping unit through this spring force. The internal pressure in the outlet device acts against the spring force of the spring unit. As the internal pressure increases due to further inflowing water, an equilibrium of forces is initially achieved between the force of the inflowing water generated by the internal pressure and the spring force of the spring unit and ultimately the internal pressure will exceed the spring force of the spring unit, whereby the locking unit is pushed back so that the steel mold unit opens and Water can flow out of the jet forming unit. This configuration means that the beam shaping unit is locked in its default setting. This prevents water from running down or at least reduces it.
Nach einer weiter vorteilhaften Ausgestaltung ist der definierbare Wert durch die Federkraft der Federeinheit einstellbar. Die Federkraft ist insbesondere konstruktiv einstellbar. Der definierbare Wert ist insbesondere dann kleiner, wenn die Federeinheit weniger Federn umfasst und/oder wenn die Federn der Federeinheit insgesamt eine kleinere Federsteifigkeit aufweisen. Der definierbare Wert ist insbesondere dann größer, wenn die Federeinheit mehr Federn umfasst und/oder wenn die Federn der Federeinheit insgesamt eine größere Federsteifigkeit aufweisen. Dadurch ist es möglich, den definierbaren Wert, bei dessen Überschreitung die Strahlformeinheit öffnet und Wasser aus der Strahlformeinheit fließen kann, genau einzustellen und so mittelbar die Reinigung der sanitären Brause zu erleichtern. Nach einer weiter vorteilhaften Ausgestaltung ist die Strahlformeinheit aus einem elastischen Material hergestellt, insbesondere aus einem Elastomer oder aus Gummi. Dies wirkt sich günstig auf die Funktionsweise der erfindungsgemäßen sanitären Brause aus und erleichtert somit deren Reinigung weiter. According to a further advantageous embodiment, the definable value can be adjusted by the spring force of the spring unit. The spring force is particularly structurally adjustable. The definable value is smaller in particular if the spring unit comprises fewer springs and/or if the springs of the spring unit have a lower spring stiffness overall. The definable value is greater in particular if the spring unit comprises more springs and/or if the springs of the spring unit have a greater spring stiffness overall. This makes it possible to precisely set the definable value, when exceeded, the jet forming unit opens and water can flow out of the jet forming unit, thus indirectly facilitating the cleaning of the sanitary shower. According to a further advantageous embodiment, the jet shaping unit is made of an elastic material, in particular an elastomer or rubber. This has a favorable effect on the functioning of the sanitary shower head according to the invention and thus further facilitates its cleaning.
Nach einer weiter vorteilhaften Ausgestaltung ist die Sperreinheit aus einem nicht-elastischen Material hergestellt, insbesondere aus einem harten Kunststoff oder aus einem Metall bzw. einer Metalllegierung. Die Sperreinheit ist insbesondere aus einem Material hergestellt, das härter bzw. fester ist als das Material aus dem die Strahlformeinheit hergestellt ist. Eine solche Werkstoffpaarung wirkt sich weiter günstig auf die Funktionsweise der erfindungsgemäßen sanitären Brause aus und erleichtert somit deren Reinigung weiter. According to a further advantageous embodiment, the locking unit is made of a non-elastic material, in particular of a hard plastic or of a metal or a metal alloy. The locking unit is in particular made of a material that is harder or stronger than the material from which the jet shaping unit is made. Such a pairing of materials has a further positive effect on the functioning of the sanitary shower head according to the invention and thus further facilitates its cleaning.
Nach einer weiter vorteilhaften Ausgestaltung weist die Strahlformeinheit zumindest eine Düse auf und weist die Sperreinheit zumindest einen Stift auf, wobei jeweils paarweise ein Stift und eine zugehörige Düse koaxial bzw. fluchtend zueinander angeordnet sind. Die Anzahl der Stifte und die Anzahl der Düsen entsprechen sich, das heißt die Brause umfasst eine Düse je Stift und umgekehrt. Die Anzahl und Anordnung der Düsen bestimmen das Stahlbild. Jeder der zumindest einen Stifte kann in Richtung bzw. entlang seiner eigenen Längsachse verschiebbar sein. According to a further advantageous embodiment, the jet shaping unit has at least one nozzle and the locking unit has at least one pin, with a pin and an associated nozzle being arranged in pairs coaxially or aligned with one another. The number of pins and the number of nozzles correspond, i.e. the shower has one nozzle per pin and vice versa. The number and arrangement of the nozzles determine the steel appearance. Each of the at least one pins can be displaceable in the direction of or along its own longitudinal axis.
Nach einer weiter vorteilhaften Ausgestaltung sind jeder der zumindest einen Stifte und jede der zumindest einen zugehörigen Düse formkomplementär zueinander ausgebildet. Ein in eine zugehörige Düse eingebrachter Stift verschließt diese Düse, sodass kein Wasser aus dieser Düse und aus der Strahlformeinheit fließen kann. Der zumindest eine Stift kann in die zugehörige Düse hinein verschiebbar sein kann aus der zugehörigen Düse heraus verschiebbar sein. According to a further advantageous embodiment, each of the at least one pins and each of the at least one associated nozzle are designed to complement each other in shape. A pin inserted into an associated nozzle closes this nozzle so that no water can flow out of this nozzle and out of the jet forming unit. The at least one pin can be displaceable into the associated nozzle and can be displaceable out of the associated nozzle.
Nach einer weiter vorteilhaften Ausgestaltung ist die Sperreinheit dazu eingerichtet, die Strahlformeinheit zu öffnen, indem der zumindest eine Stift aus der zumindest einen zugehörigen Düse herausgeschoben wird, das heißt durch Herausschieben des zumindest einen Stifts aus der zumindest einen zugehörigen Düse. Durch dieses Herausschieben öffnet sich der Strömungskanal der zumindest einen zugehörigen Düse, sodass das zuströmende Wasser durch den durch das Herausschieben freigewordenen Strömungskanal aus der Strahlformeinheit der Auslasseinrichtung herausfließen kann. According to a further advantageous embodiment, the locking unit is set up to open the jet shaping unit by pushing the at least one pin out of the at least one associated nozzle, that is to say by pushing out the at least one pin the at least one associated nozzle. This pushing out opens the flow channel of the at least one associated nozzle, so that the inflowing water can flow out of the jet forming unit of the outlet device through the flow channel that became free due to the pushing out.
Nach einer weiter vorteilhaften Ausgestaltung ist die Sperreinheit dazu eingerichtet, die Strahlformeinheit zu sperren, indem der zumindest eine Stift in die zumindest eine zugehörige Düse hineingeschoben wird, das heißt durch Hineinschieben des zumindest einen Stifts in die zumindest eine zugehörige Düse. Durch dieses Hineinschieben, wobei Stift und Düse insbesondere formkomplementär zueinander ausgebildet sind, schließt sich der Strömungskanal der zumindest einen zugehörigen Düse, sodass das zuströmende Wasser daran gehindert wird, durch den Strömungskanal aus der Strahlformeinheit der Auslasseinrichtung herauszufließen. Dadurch, dass die Strahlformeinheit gesperrt ist, ist ein Nachlaufen von Wasser verhindert oder wenigstens vermindert. According to a further advantageous embodiment, the locking unit is set up to lock the jet shaping unit by pushing the at least one pin into the at least one associated nozzle, that is to say by pushing the at least one pin into the at least one associated nozzle. As a result of this pushing in, with the pin and nozzle being designed in particular with a shape that complements one another, the flow channel of the at least one associated nozzle closes, so that the inflowing water is prevented from flowing out of the jet shaping unit of the outlet device through the flow channel. Because the jet forming unit is blocked, water running over is prevented or at least reduced.
Die vorliegende Erfindung wird nachfolgend anhand der Figur näher erläutert. Darin ist eine vorteilhafte Ausführungsform der Erfindung gezeigt, wobei die Erfindung nicht auf diese vorteilhafte Ausführungsform beschränkt ist. Gleiche Bauteile sind in der Figur stets mit den gleichen Bezugszeichen versehen und sind daher grundsätzlich nur einmal benannt bzw. erwähnt. Es zeigt im Einzelnen die The present invention is explained in more detail below with reference to the figure. An advantageous embodiment of the invention is shown therein, although the invention is not limited to this advantageous embodiment. The same components are always provided with the same reference numbers in the figure and are therefore basically only named or mentioned once. It shows in detail the
Figur 1 eine Ausführungsform der erfindungsgemäßen sanitären Brause in einer Schnittdarstellung. Figure 1 shows an embodiment of the sanitary shower according to the invention in a sectional view.
Die in der Figur gezeigte erfindungsgemäße sanitäre Brause dient zur Bereitstellung von Wasser und umfasst eine Auslasseinrichtung 1, eine Wasserführung 2 in Form eines Wasserkanals und einen Wassereinlass 3, der mit einer Sanitärarmatur verbindbar ist. Die Auslasseinrichtung 1, die Wasserführung 2 und der Wassereinlass 3 sind fluidisch miteinander verbunden, sodass durch den Wassereinlass 3 in die Brause einströmendes Wasser über die Wasserführung 2 in die Auslasseinrichtung 1 und schließlich aus dieser heraus fließen kann. The sanitary shower according to the invention shown in the figure serves to provide water and comprises an outlet device 1, a water guide 2 in the form of a water channel and a water inlet 3, which can be connected to a sanitary fitting. The outlet device 1, the water guide 2 and the water inlet 3 are fluidly connected to one another, so that Water flowing into the shower through the water inlet 3 can flow via the water guide 2 into the outlet device 1 and finally out of it.
Die Auslasseinrichtung 1 umfasst eine Strahlformeinheit 4 und eine relativ zu der Strahlformeinheit 4 bewegliche Sperreinheit 5. Die Auslasseinrichtung 1 bildet einen Raum 6, der mit dem zuströmenden Wasser füllbar ist. Die Sperreinheit 5 ist dazu eingerichtet, wenn der durch zuströmendes Wasser entstehende Druck in der Auslasseinrichtung 1, das heißt in dem Raum 6, einen definierbaren Wert übersteigt, die Strahlformeinheit 4 zu öffnen, und ansonsten, das heißt wenn der durch zuströmendes Wasser entstehende Druck in der Auslasseinrichtung 1 den definierbaren Wert nicht übersteigt oder darunter liegt, die Strahlformeinheit 4 zu sperren. Die Relativbewegungen zwischen der Strahlformeinheit 4 und der Sperreinheit 5 entsprechen einer mechanischen Reinigung der Strahlformeinheit 4, da durch diese Relativbewegungen Ablagerungen wie beispielsweise Kalkablagerungen, die sich möglicherweise in der Strahlformeinheit 4 angesammelt haben, zerstoßen und abgetragen werden. The outlet device 1 comprises a jet shaping unit 4 and a locking unit 5 that is movable relative to the jet shaping unit 4. The outlet device 1 forms a space 6 which can be filled with the inflowing water. The locking unit 5 is set up to open the jet forming unit 4 when the pressure resulting from inflowing water in the outlet device 1, that is to say in the space 6, exceeds a definable value, and otherwise, that is when the pressure resulting from inflowing water in of the outlet device 1 does not exceed or is below the definable value to block the jet shaping unit 4. The relative movements between the jet shaping unit 4 and the locking unit 5 correspond to a mechanical cleaning of the jet shaping unit 4, since these relative movements crush and remove deposits such as lime deposits that may have accumulated in the jet shaping unit 4.
Die Auslasseinrichtung 1 umfasst zusätzlich eine Federeinheit 7, die fest mit der Sperreinheit 5 verbunden ist und diese federnd lagert. Die Federeinheit 7 umfasst vier Druckfedern 8. Außerdem umfasst die Federeinheit ein Dichtungselement 9, um die Federeinheit 7 fluiddicht von dem zuströmenden Wasser abzuschirmen. Die Federeinheit 7 drückt die Sperreinheit 5 in Richtung der Strahlformeinheit 4. Der durch das zuströmende Wasser entstehende Innendruck in der Auslasseinrichtung 1 wirkt gegen die Federkraft der Federeinheit 7. Die Strahlformeinheit 4 ist also im wasserdrucklosen Zustand der sanitären Brause, das heißt wenn der Innendruck in der Auslasseinrichtung 1 den definierbaren Druckwert nicht übersteigt, gesperrt. Durch Änderung der Anzahl oder der jeweiligen Federsteifigkeit der Druckfedern 8 ist der definierbare Druckwert wunschgemäß einstellbar bzw. anpassbar. Die Strahlformeinheit 4 weist acht Düsen 10 auf und die Sperreinheit 5 weist acht Stifte 11 auf. Jeweils paarweise sind ein Stift 11 und eine zugehörige Düse 10 koaxial zueinander angeordnet, wobei jeder Stift 11 entlang seiner eigenen Längsachse in die zugehörige Düse 10 hinein- und herausschiebbar ist. Jeder Stift 11 und jede zugehörige Düse 10 sind formkomplementär zueinander ausgebildet, das heißt jeder Stift 11 füllt den Strömungskanal jeder zugehörigen Düse 10 im Wesentlichen voll aus, wenn dieser in die Düse 10 hineingeschoben ist, sodass die Düse 10 in diesem Zustand verschlossen bzw. gesperrt ist und kein Wasser durch die Düse 10 fließen kann. The outlet device 1 additionally includes a spring unit 7, which is firmly connected to the locking unit 5 and supports it resiliently. The spring unit 7 includes four compression springs 8. The spring unit also includes a sealing element 9 in order to shield the spring unit 7 from the inflowing water in a fluid-tight manner. The spring unit 7 presses the locking unit 5 in the direction of the jet shaping unit 4. The internal pressure in the outlet device 1 created by the inflowing water acts against the spring force of the spring unit 7. The jet shaping unit 4 is therefore in the water-free state of the sanitary shower, that is, when the internal pressure is in the outlet device 1 does not exceed the definable pressure value, blocked. By changing the number or the respective spring stiffness of the compression springs 8, the definable pressure value can be set or adapted as desired. The jet shaping unit 4 has eight nozzles 10 and the locking unit 5 has eight pins 11. A pin 11 and an associated nozzle 10 are arranged coaxially to one another in pairs, with each pin 11 being able to be pushed in and out of the associated nozzle 10 along its own longitudinal axis. Each pin 11 and each associated nozzle 10 are designed to complement each other in shape, that is, each pin 11 essentially completely fills the flow channel of each associated nozzle 10 when it is pushed into the nozzle 10, so that the nozzle 10 is closed or blocked in this state and no water can flow through the nozzle 10.
Die Sperreinheit 5 mit ihren Stiften 11 ist dazu eingerichtet, die Strahlformeinheit 4 mit ihren Düsen 10 zu öffnen, indem die Stifte 11 aus den jeweils zugehörigen Düsen 10 herausgeschoben werden. Die Stifte 11 werden aus den jeweils zugehörigen Düsen 10 herausgeschoben, wenn der durch das zuströmende Wasser in der Auslasseinrichtung 1 entstehende Innendruck den durch die Anzahl und die jeweiligen Federsteifigkeiten der Druckfedern 8 der Federeinheit 7 definierten Druckwert übersteigt. The locking unit 5 with its pins 11 is set up to open the jet shaping unit 4 with its nozzles 10 by pushing the pins 11 out of the associated nozzles 10. The pins 11 are pushed out of the associated nozzles 10 when the internal pressure created by the inflowing water in the outlet device 1 exceeds the pressure value defined by the number and the respective spring stiffness of the compression springs 8 of the spring unit 7.
Die Sperreinheit 5 ist außerdem dazu eingerichtet, die Strahlformeinheit 4 zu sperren, indem die Stifte 11 der Sperreinheit 5 in die jeweils zugehörigen Düsen 10 hineingeschoben werden. Die Stifte 11 werden in die jeweils zugehörigen Düsen 10 hineingeschoben, wenn der durch das zuströmende Wasser in der Auslasseinrichtung 1 entstehende Innendruck den durch die Anzahl und die jeweiligen Federsteifigkeiten der Druckfedern 8 der Federeinheit 7 definierten Druckwert unterschreitet oder nicht übersteigt. Bezugszeichenliste The locking unit 5 is also set up to lock the jet shaping unit 4 by pushing the pins 11 of the locking unit 5 into the associated nozzles 10. The pins 11 are pushed into the associated nozzles 10 when the internal pressure created by the inflowing water in the outlet device 1 falls below or does not exceed the pressure value defined by the number and the respective spring stiffness of the compression springs 8 of the spring unit 7.
