Definitions
- the invention relates to a shower device with the water supply handle part and the shower head, which has a plurality of shower holes and associated with them and adapted in diameter pins, the pins and the plate having the shower holes are displaceable relative to each other.
- shower holes formed in the cover plate tend to clog, which is particularly favored by calcareous water.
- shower facilities were developed early on, in which plates with pins were arranged in the shower head, which could be pushed through the blocked shower holes if necessary.
- a shower device in which a slidable plate with pins is arranged within the shower head, which is pushed forward under water pressure.
- the pens already reach into the shower holes in the rest position and are pushed outwards by the water pressure in order to then shape the jet.
- the pins are therefore only used to a minor extent to maintain the exclusion cross section of the shower holes.
- a shower device with a shower head is known from US Pat. No. 1,982,538, in which the displaceable plate can be moved via an adjusting lever.
- the pins clean the shower holes when they pierce and ensure a predetermined jet shape.
- DE-OS 37 07 885 shows a shower device in which different jet shapes can be specified via a switching device.
- the pins assigned to a ring or a plate become the individual shower holes inserted so that the shower hole is cleaned from the inside each time it is switched.
- a disadvantage of the known shower devices is that a switchover process is required in each case in order to initiate the cleaning process, or it is important for the user to make sure that the pens pass sufficiently through the shower holes.
- the pins In the embodiment known from DE-PS 711 583, in which the pins extend into the shower holes even in the idle state, it is disadvantageous that the pins must have a significantly smaller diameter because of the guidance of the water jet, so that the cleaning effect is limited. Any deposits of lime, for example, cannot generally be removed with this device, which then also depends on the level of the water pressure.
- the shower holes are only cleaned during the switching process. If the switchover device is not used for a long time, the shower holes can become clogged, so that the necessary and desired cleaning process cannot be achieved even with the help of the switchover device.
- the invention is therefore based on the object of providing a shower device with a shower head, the shower holes of which are automatically cleaned when the spray position is switched on.
- the object is achieved in that the pins are fastened to the housing of the shower head and that between these pins and a cover plate protecting the shower head outlet, a nozzle plate equipped with the shower holes and sealing against the water supply is guided by the pins and against the force on the cover plate supporting springs is slidably arranged and that the nozzle plate on the one hand with the Pins and on the other hand is correspondingly formed with recesses in the cover plate.
- the shower holes are automatically cleaned practically after each use, namely by then moving the nozzle plate with the shower holes through the springs against the pins, so that the pins rest in the corresponding shower holes in this state of rest.
- the nozzle plate is displaced against the force of the springs, so that the shower holes are then fully functional.
- the shower holes which tend to clog remain protected in their position by the pins and the water can flow out of the shower head, for example, by taking up air. But since the normal shower position is the spray position, in which the shower holes come into operation, practically every time the water is switched on or the cleaning process is switched off. This means that shower equipment is always functional.
- the pins are part of the water supply and are fixed with this in the housing.
- the interior construction of such a shower head can thus be simplified, the pins or at least the holders for them being able to be produced in one operation with the water supply. This ensures stable storage and formation of the pins. This, in turn, guarantees that the nozzle plate can be pushed onto the pens via the spring force when the water is turned off, in order to clean the shower holes or to prevent dirt or limescale from forming from the outset.
- Pins to be inserted into the shower holes as optimally as possible are specified if, as provided according to the invention, the pins have cylindrical end pieces which correspond to the shower holes, while the pockets connected to the water supply have the shape of a pointed truncated cone. In particular in the embodiment of the nozzle plate described further below, this guarantees that the shower holes are kept open and, at the same time, the nozzle-shaped outlet of the individual shower holes in the nozzle plate is cleared.
- the pins are secure and can be made from a suitable material.
- the invention provides that the pins are designed as steel pins and the pockets as plastic or metal parts. Of course, it is also possible to produce pens and bags from the same material, for example as a plastic component common to the water supply.
- shower facilities of this type can be equipped with single or multi-function shower heads.
- cleaning of the shower holes is ensured according to the invention by the water supply having two channels, one of which ends above and the other below the nozzle plate and which can alternately be connected to the water supply or the handle part via a switch.
- the inflowing water is only used in the spray position to move the nozzle plate away from the pins and then to clear the way for the water through the clean or cleaned shower holes.
- the water is guided past the nozzle plate so that it remains in its rest position and the water can flow out, for example enriched with air, in a suitable and desired manner. If, on the other hand, the water flows onto the nozzle plate and moves it, this becomes thereby ensuring that the nozzle plate is sealed against the edges of the water supply or the interior of the shower head.
- the changeover switch is expediently mounted in such a way that it is positioned at the transition from the handle part to the shower head and is designed as a rotary distributor, so that the changeover process can easily be accomplished with one finger.
- a simple and expedient design of the rotary distributor provides that it is rotatable with its inlet end on the pipe end piece of the handle part and is secured in the water supply via knobs and slot guide.
- the desired smoothness is achieved and at the same time the possibility is given to make a change during the water inflow.
- the rotary distributor is guided from one end position to the other via the knobs rotatable in the slot guide.
- the nozzle plate has nozzle-shaped projections on the side facing the cover plate. This gives the possibility of optimally shaping the shape of the water jet or jets, this predetermined shape being always guaranteed for the further period of use, because the cleaning process already described via the fixed pins guarantees this.
- the nozzle-shaped design of the approaches also has the advantage that there is a certain guide for the pins, which are still in the end position in the end position even with the displaced nozzle plate, so that a hook or the like. cannot occur when the nozzle plate is pushed back over the springs.
- the nozzle-shaped attachments have an outlet nozzle on the outlet side. That is the possibility given to replace the nozzle plate and thus the outlet nozzle shape when the user desires a specific form of water jet. The effort involved is relatively low.
- a stable position of the nozzle plate on the springs on the one hand and a secure reciprocation of the nozzle plate on the other hand is ensured if the springs are arranged between two perforated or nozzle circles guided by a cam assigned to the cover plate. It is expedient to arrange three springs distributed over the circumference between the cover and nozzle plate in order to keep the number of springs as low as possible and thus the weight of the shower head. The three springs distributed over the circumference ensure an optimal position and the cams ensure uniform guiding of the springs, which cannot slide out of their specified position due to the back and forth movement of the nozzle plate.
- the specially designed nozzle plate with its nozzle-shaped attachments can be advanced beyond the cover plate in order not to have any negative influence on the water jets. This is ensured by the recesses in the cover plate having webs pointing towards the center of the circle, the free edges of which are arranged and designed to guide the nozzle-shaped projections of the nozzle plate.
- the nozzle-shaped lugs of the nozzle plate are thus reliably guided when the nozzle plate is displaced and when the cover plate is pierced, with an annular recess remaining around the nozzle-shaped lugs, which is provided for the water to flow out in the other functional positions.
- the invention is characterized in particular by the fact that a shower device with a shower head is created which, regardless of whether it is designed as a single or multiple function shower, always flawlessly from the water has shower holes to flow through. These shower holes are kept open by the inserted pins in the idle state, so that when the nozzle plate with its shower holes is moved, a perfect flow is always guaranteed.
- the nozzle plate is mechanically pushed into this rest position via the springs, while it is held in the working position by the inflowing and flowing water. It is thereby achieved that practically every time the shower device is used in the spray position, a cleaning process runs automatically, as a result of which an always functional shower device or a corresponding shower head is kept available. With a corresponding design of the water supply in a multi-function shower device, the water is guided in the spray position onto the nozzle plate, while it can be guided past the nozzle plate for other functions.
- FIGS. 1 and 4 consists of the handle part (2), which is hollow and through which the water can flow and from the shower head (3).
- the handle part (2) is shown in cross section in Fig. 4. It is conceivable that a water hose or tube is integrated in this handle part (2).
- the embodiment shown in FIGS. 1 and 4 is, however, the more expedient and simpler one.
- a rotary distributor (4) is arranged in the embodiment shown in FIG. 1, so as to feed water for the spray position or the soft position via the water supply (5). Further details are explained further below.
- the water supply (5) is integrated in the housing (6) of the shower head (3). This is expediently a component which is explained in more detail with reference to FIGS. 5 and 8, a large number of pins (7, 8) being part of the water supply (5) or else being firmly connected to it.
- This nozzle plate (9) has nozzle-shaped projections (10) which protrude above the nozzle plate (9) on the side (11) facing the cover plate (14). These nozzle-shaped projections (10) extend into the corresponding recesses (16) of the cover plate (14), the cover plate (14) covering and securing the shower head spout (15).
- the individual shower holes (12, 13) are formed in the nozzle-shaped projections (10) and are thus pierced through the pins (7, 8) in the rest position.
- the nozzle-shaped projections (10) which protrude above the nozzle plate (9) are supported in the region of the recesses (16) of the cover plate (14) via webs (18, 19), the free edges (20) of these webs (18, 19) are designed so that the nozzle-shaped lugs (10) rest. This results in a circular, continuous flow ring for the water when the soft position is set, in which case, as is shown in FIG. 7, air can flow into the interior of the shower head (3) in order to mix with the water.
- Fig. 2 shows a plan view of the cover plate (14), in particular the hole and nozzle circles (23, 24) can be seen and the webs (18, 19) formed in the individual recesses (16). Also indicated are the cams (25) on which the springs (17), which are not shown here, are supported or are guided through them. This cam (25) can also be seen in FIG. 3, a section through the cover plate (14), the section through recesses (16) of the hole or nozzle circles (23, 24) being shown on the opposite side.
- FIG. 6 and 7 show the water flow when the spray position is switched on and in FIG. 7 the soft position, for which purpose the water is passed through the channel (28) and, according to FIG. 7, through the channel (29).
- 5 and 8 show a section through the water supply (5) or the corresponding part, which is fixed in the housing (6). It is clearly recognizable that the water in the soft position, the switch (30) is passed into the channel (29), from where it is distributed in the middle past the nozzle plate (9) onto the cover plate (14). Air is sucked in centrally over the suction part (41), which is indicated by the arrows, so that with this soft setting water-air mixture can flow out through the recesses (16).
- This shower water outlet is labeled (42).
- the switch (30) or rotary distributor (4) is a part that can be easily operated with a finger, which, as already mentioned, is arranged between the shower head (3) and the handle part (2) and with the inlet end (31) in the water supply (5) or on the pipe end piece (32).
- the version shown in these figures represents a two-function shower. In the case of a single-function shower, this changeover switch (30) is dispensed with and the water flows exclusively as indicated in FIG. 6 via the water supply (5) and the channel (28) onto the nozzle plate ( 9).
- Fig. 8 shows the formation of the pins (7, 8).
- the pockets (37) are in turn directly connected to the component, which is referred to here as water supply (5).
- Fig. 9 shows the nozzle plate (9) in plan view and Fig. 10 in cross section.
- This nozzle plate (9) is equipped with the nozzle-shaped lugs (10) recognizable in both corridors, the latter being shown enlarged in FIG. 11. It is clear that these approaches take the pins (7, 8), not shown here, whereby the shape of both parts ensures that when Moving the nozzle plate (9) up and down may cause caking, so that they are then carried away to the outside by the outlet nozzles (39, 40) with the water, so that an always clean outlet nozzle (39, 40) is available.

Abstract
Description
Die Erfindung betrifft eine Duscheinrichtung mit dem zugleich zur Wasserzuführung dienenden Griffteil und dem Brausekopf, der eine Vielzahl von Brauselöchern und diesen zugeordnete und vom Durchmesser her angepaßte Stifte aufweist, wobei die Stifte und die die Brauselöcher aufweisende Platte relativ zueinander verschieblich sind.The invention relates to a shower device with the water supply handle part and the shower head, which has a plurality of shower holes and associated with them and adapted in diameter pins, the pins and the plate having the shower holes are displaceable relative to each other.
Bei den Brauseköpfen von Duscheinrichtungen neigen die in der Abdeckplatte ausgebildeten Brauselöcher zum Verstopfen, was insbesondere durch kalkhaltige Wässer begünstigt wird. Schon frühzeitig sind Duscheinrichtungen entwickelt worden, bei denen im Brausekopf Platten mit Stiften angeordnet wurden, die bei Bedarf durch die verstopften Brauselöcher hindurchgedrückt werden konnten.In the shower heads of shower facilities, the shower holes formed in the cover plate tend to clog, which is particularly favored by calcareous water. Shower facilities were developed early on, in which plates with pins were arranged in the shower head, which could be pushed through the blocked shower holes if necessary.
Aus der DE-PS 711 583 ist eine Duscheinrichtung bekannt, bei der innerhalb des Brausekopfes eine verschiebbare Platte mit Stiften angeordnet ist, die unter Wasserdruck nach vorne geschoben wird. Die Stifte greifen bereits in Ruhestellung in die Brauselöcher und werden durch den Wasserdruck nach außen geschoben, um dann den Strahl zu formen. Die Stifte dienen also hier nur untergeordnet zur Aufrechterhaltung des Ausschlußquerschnittes der Brauselöcher.From DE-PS 711 583 a shower device is known in which a slidable plate with pins is arranged within the shower head, which is pushed forward under water pressure. The pens already reach into the shower holes in the rest position and are pushed outwards by the water pressure in order to then shape the jet. The pins are therefore only used to a minor extent to maintain the exclusion cross section of the shower holes.
Aus der US-PS 1 982 538 ist dagegen eine Duscheinrichtung mit Brausekopf bekannt, bei dem die verschiebbare Platte über einen Einstellhebel bewegt werden kann. Die Stifte säubern beim Durchstoßen die Brauselöcher und gewährleisten eine vorgegebene Strahlform.On the other hand, a shower device with a shower head is known from US Pat. No. 1,982,538, in which the displaceable plate can be moved via an adjusting lever. The pins clean the shower holes when they pierce and ensure a predetermined jet shape.
Die DE-OS 37 07 885 zeigt eine Duscheinrichtung, bei der über eine Umschalteinrichtung unterschiedliche Strahlformen vorgegeben werden können. Beim Umschalten von der einen auf die andere Strahlform werden die einem Ring bzw. einer Platte zugeordneten Stifte in die einzelnen Brauselöcher eingeschoben, so daß bei jedem Umschalten eine Reinigung des Brauseloches von innen her erfolgt.DE-OS 37 07 885 shows a shower device in which different jet shapes can be specified via a switching device. When switching from one to the other jet shape, the pins assigned to a ring or a plate become the individual shower holes inserted so that the shower hole is cleaned from the inside each time it is switched.
Bei den bekannten Duscheinrichtungen ist von Nachteil, daß jeweils ein Umschaltvorgang erforderlich ist, um den Reinigungsvorgang einzuleiten bzw. es auf die Sorgfalt des Benutzers ankommt, ob er die Stifte weitgenug durch die Brauselöcher hindurchführt. Bei der aus der DE-PS 711 583 bekannten Ausführung, bei der die Stifte auch im Ruhezustand in die Brauselöcher hineinreichen, ist nachteilig, daß die Stifte wegen der Führung des Wasserstrahls einen deutlich geringeren Durchmesser aufweisen müssen, so daß der Reinigungseffekt begrenzt ist. Einmal aufgetretene Ansätze beispielsweise von Kalk können mit dieser Einrichtung, die ja dann auch noch von der Höhe des Wasserdrucks abhängt, in der Regel nicht beseitigt werden. Bei der aus der DE-OS 37 07 885 bekannten Lösung ist besonders nachteilig, daß eine Reinigung der Brauselöcher nur beim Umschaltvorgang eintritt. Wird also die Umschalteinrichtung längere Zeit nicht benutzt, können sich die Brauselöcher zusetzen, so daß dann auch mit Hilfe der Umschalteinrichtung der notwendige und gewünsche Reinigungsvorgang nicht zu erreichen ist.A disadvantage of the known shower devices is that a switchover process is required in each case in order to initiate the cleaning process, or it is important for the user to make sure that the pens pass sufficiently through the shower holes. In the embodiment known from DE-PS 711 583, in which the pins extend into the shower holes even in the idle state, it is disadvantageous that the pins must have a significantly smaller diameter because of the guidance of the water jet, so that the cleaning effect is limited. Any deposits of lime, for example, cannot generally be removed with this device, which then also depends on the level of the water pressure. In the solution known from DE-OS 37 07 885, it is particularly disadvantageous that the shower holes are only cleaned during the switching process. If the switchover device is not used for a long time, the shower holes can become clogged, so that the necessary and desired cleaning process cannot be achieved even with the help of the switchover device.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Duscheinrichtung mit einem Brausekopf zu schaffen, dessen Brauselöcher selbsttätig bei Einschalten der Sprühstellung gereinigt sind.The invention is therefore based on the object of providing a shower device with a shower head, the shower holes of which are automatically cleaned when the spray position is switched on.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Stifte am Gehäuse des Brausekopfes befestigt sind und daß zwischen diesen Stiften und einer den Brausekopfauslauf schützenden Abdeckplatte eine mit den Brauselöchern ausgerüstete und gegen die Wasserzuführung abschließende Düsenplatte von den Stiften geführt und gegen die Kraft sich auf der Abdeckplatte abstützender Federn verschieblich angeordnet ist und daß die Düsenplatte einerseits mit den Stiften und andererseits mit Ausnehmungen in der Abdeckplatte korrespondierend ausgebildet ist.The object is achieved in that the pins are fastened to the housing of the shower head and that between these pins and a cover plate protecting the shower head outlet, a nozzle plate equipped with the shower holes and sealing against the water supply is guided by the pins and against the force on the cover plate supporting springs is slidably arranged and that the nozzle plate on the one hand with the Pins and on the other hand is correspondingly formed with recesses in the cover plate.
Bei einer derartigen Duscheinrichtung werden die Brauselöcher praktisch nach jedem Einsatz automatisch gereinigt, indem nämlich dann die Düsenplatte mit den Brauselöchern durch die Federn gegen die Stifte verschoben wird, so daß in diesem Ruhestand die Stifte in den entsprechenden Brauselöchern ruhen. Bei der Funktion, bei der die Brauselöcher beansprucht werden und zum Zusetzen neigen, wird die Düsenplatte gegen die Kraft der Federn verschoben, so daß die Brauselöcher dann voll funktionsfähig sind. Wird bei einer Mehrfachfunktionsduscheinrichtung bzw. einem Mehrfachfunktionbrausekopf durch entsprechende Umstellung eine andere Funktion eingestellt, so bleiben die zum Zusetzen neigenden Brauselöcher durch die Stifte geschützt in ihrer Position und das Wasser kann beispielsweise unter Aufnahme von Luft aus dem Brausekopf herausströmen. Da aber die normale Duschstellung die Sprühstellung ist, bei der die Brauselöcher in Funktion treten, wird praktisch mit jedem Einschalten des Wassers bzw. mit dem Abstellen der Reinigungsprozeß bewirkt. Eine immer funktionstüchtige Duscheinrichtung ist somit gegeben.In such a shower device, the shower holes are automatically cleaned practically after each use, namely by then moving the nozzle plate with the shower holes through the springs against the pins, so that the pins rest in the corresponding shower holes in this state of rest. In the function in which the shower holes are stressed and tend to clog, the nozzle plate is displaced against the force of the springs, so that the shower holes are then fully functional. If, in the case of a multi-function shower device or a multi-function shower head, another function is set by appropriate conversion, the shower holes which tend to clog remain protected in their position by the pins and the water can flow out of the shower head, for example, by taking up air. But since the normal shower position is the spray position, in which the shower holes come into operation, practically every time the water is switched on or the cleaning process is switched off. This means that shower equipment is always functional.
Nach einer zweckmäßigen Ausbildung der Erfindung ist vorgesehen, daß die Stifte Teil der Wasserzuführung und mit dieser im Gehäuse festgelegt sind. Damit kann der Innenbau eines derartigen Brausekopfes vereinfacht werden, wobei die Stifte oder zumindest die Halterungen dafür in einem Arbeitsgang mit der Wasserzuführung hergestellt werden können. Eine stabile Lagerung und Ausbildung der Stifte ist so gewährleistet. Damit wiederum kann die Düsenplatte über die Federkraft bei Abstellen des Wassers garantiert auf die Stifte aufgeschoben werden, um die Reinigung der Brauselöcher zu erreichen bzw. um das Ansetzen von Schmutzteilen bzw. Kalkteilen von vornherein zu verhindern.According to an expedient embodiment of the invention it is provided that the pins are part of the water supply and are fixed with this in the housing. The interior construction of such a shower head can thus be simplified, the pins or at least the holders for them being able to be produced in one operation with the water supply. This ensures stable storage and formation of the pins. This, in turn, guarantees that the nozzle plate can be pushed onto the pens via the spring force when the water is turned off, in order to clean the shower holes or to prevent dirt or limescale from forming from the outset.
Möglichst optimal in die Brauselöcher einzuführende Stifte werden vorgegeben, wenn, wie erfindungsgemäß vorgesehen, die Stifte zylindrische Endstücke aufweisen, die mit den Brauselöchern korrespondierend ausgebildet sind, während die mit der Wasserzuführung verbundenen Taschen die Form eines spitzen Kegelstumpfes aufweisen. Insbesondere bei der noch weiter hinten beschriebenen Ausführung der Düsenplatte ist somit ein Offenhalten der Brauselöcher garantiert und gleichzeitig ein Freischaben des düsenförmigen Auslaufes der einzelnen Brauselöcher in der Düsenplatte. Außerdem sind die Stifte sicher und können aus zweckmäßigem Werkstoff hergestellt werden. Hierzu sieht die Erfindung vor, daß die Stifte als Stahlstifte und die Taschen als Kunststoff- oder Metallteile ausgebildet sind. Selbstverständlich ist es auch möglich, Stifte und Taschen aus dem gleichen Material herzustellen, beispielsweise als mit der Wasserzuführung gemeinsames Kunststoffbauteil.Pins to be inserted into the shower holes as optimally as possible are specified if, as provided according to the invention, the pins have cylindrical end pieces which correspond to the shower holes, while the pockets connected to the water supply have the shape of a pointed truncated cone. In particular in the embodiment of the nozzle plate described further below, this guarantees that the shower holes are kept open and, at the same time, the nozzle-shaped outlet of the individual shower holes in the nozzle plate is cleared. In addition, the pins are secure and can be made from a suitable material. For this purpose, the invention provides that the pins are designed as steel pins and the pockets as plastic or metal parts. Of course, it is also possible to produce pens and bags from the same material, for example as a plastic component common to the water supply.
Weiter vorne ist bereits darauf hingewiesen worden, daß derartige Duscheinrichtungen mit Ein- oder Mehrfachfunktionbrauseköpfen ausgerüstet werden können. Für eine Zweifunktionsbrause beispielsweise wird erfindungsgemäß eine Reinigung der Brauselöcher sichergestellt, indem die Wasserzuführung über zwei Kanäle verfügt, von denen einer oberhalb und der andere unterhalb der Düsenplatte endet und die wechselweise über einen Umschalter mit der Wasserzuführung bzw. dem Griffteil verbindbar sind. Damit wird das zuströmende Wasser nur in der Sprühstellung dazu verwendet, die Düsenplatte von den Stiften wegzubewegen, um dann den Weg für das Wasser durch die saubergehaltenen oder gesäuberten Brauselöcher freizugeben. Bei der zweiten Funktion wird das Wasser an der Düsenplatte vorbeigeführt, so daß diese in ihrer Ruhestellung beharrt und das Wasser auf zweckmäßige und gewünschte Weise beispielsweise mit Luft angereichert ausströmen kann. Strömt das Wasser dagegen auf die Düsenplatte und verschiebt diese, so wird dies dadurch gewährleistet, daß die Düsenplatte gegen die Ränder der Wasserzuführung bzw. des Innenbereiches des Brausekopfes abgedichtet ist.It has already been pointed out above that shower facilities of this type can be equipped with single or multi-function shower heads. For a two-function shower head, for example, cleaning of the shower holes is ensured according to the invention by the water supply having two channels, one of which ends above and the other below the nozzle plate and which can alternately be connected to the water supply or the handle part via a switch. This means that the inflowing water is only used in the spray position to move the nozzle plate away from the pins and then to clear the way for the water through the clean or cleaned shower holes. In the second function, the water is guided past the nozzle plate so that it remains in its rest position and the water can flow out, for example enriched with air, in a suitable and desired manner. If, on the other hand, the water flows onto the nozzle plate and moves it, this becomes thereby ensuring that the nozzle plate is sealed against the edges of the water supply or the interior of the shower head.
Der Umschalter ist zweckmäßig so angebracht, daß er am Übergang Griffteil/Brausekopf positioniert und als Drehverteiler ausgebildet ist, so daß der Umschaltvorgang leicht quasi mit einem Finger zu bewerkstelligen ist.The changeover switch is expediently mounted in such a way that it is positioned at the transition from the handle part to the shower head and is designed as a rotary distributor, so that the changeover process can easily be accomplished with one finger.
Eine einfache und zweckmäßige Ausführung des Drehverteilers sieht vor, daß er mit seinem Zulaufende auf dem Rohrendstück des Griffteils drehbar und in der Wasserzuführung über Noppen und Schlitzführung gesichert gelagert ist. Damit ist die gewünschte Leichtgängigkeit erreicht und zugleich auch die Möglichkeit gegeben, während des Wasserzustroms eine Umstellung vorzunehmen. Der Drehverteiler wird dabei über den in der Schlitzführung drehbaren Noppen von einer in die andere Endstellung geführt.A simple and expedient design of the rotary distributor provides that it is rotatable with its inlet end on the pipe end piece of the handle part and is secured in the water supply via knobs and slot guide. The desired smoothness is achieved and at the same time the possibility is given to make a change during the water inflow. The rotary distributor is guided from one end position to the other via the knobs rotatable in the slot guide.
In der Düsenplatten sind nicht nur einfache Brauselöcher ausgebildet, die von den Stiften durchstoßen werden, sondern zur besonderen Formgebung der Wasserstrahlen ist vorgesehen, daß die Düsenplatte auf der der Abdeckplatte zugewandten Seite düsenförmige Ansätze aufweist. Somit ist die Möglichkeit gegeben, die Form des Wasserstrahls bzw. der Wasserstrahlen optimal zu formen, wobei diese einmal vorgegebene Form für den weiteren Benutzungszeitraum immer gewahrleistet ist, weil der schon beschriebene Reinigungsvorgang über die feststehenden Stifte dies garantiert. Die düsenförmige Ausbildung der Ansätze hat darüber hinaus den Vorteil, daß es eine gewisse Führung für die Stifte gibt, die auch bei der verschobenen Düsenplatte in deren Endposition immer noch im Bereich der Ansätze sich befinden, so daß ein Verhaken o.ä. beim Zurückschieben der Düsenplatte über die Federn nicht auftreten kann. Zur Optimierung ist dabei vorgesehen, daß die düsenförmigen Ansätze auslaufseitig eine Auslaufdüse aufweisen. Damit ist die Möglichkeit gegeben, die Düsenplatte und damit die Auslaufdüsenform auszutauschen, wenn der Benutzer eine ganz bestimmte Form von Wasserstrahl wünscht. Der damit verbundene Aufwand ist relativ gering.Not only are simple shower holes formed in the nozzle plates which are pierced by the pins, but for the special shape of the water jets it is provided that the nozzle plate has nozzle-shaped projections on the side facing the cover plate. This gives the possibility of optimally shaping the shape of the water jet or jets, this predetermined shape being always guaranteed for the further period of use, because the cleaning process already described via the fixed pins guarantees this. The nozzle-shaped design of the approaches also has the advantage that there is a certain guide for the pins, which are still in the end position in the end position even with the displaced nozzle plate, so that a hook or the like. cannot occur when the nozzle plate is pushed back over the springs. To optimize this, it is provided that the nozzle-shaped attachments have an outlet nozzle on the outlet side. That is the possibility given to replace the nozzle plate and thus the outlet nozzle shape when the user desires a specific form of water jet. The effort involved is relatively low.
Eine stabile Lage der Düsenplatte auf den Federn einerseits und ein sicheres Hin- und Herbewegen der Düsenplatte andererseits ist gewährleistet, wenn die Federn zwischen zwei Loch- oder Düsenkreisen von einem der Abdeckplatte zugeordneten Nocken geführt angeordnet sind. Dabei ist es zweckmäßig, über den Umfang verteilt drei Federn zwischen Abdeck- und Düsenplatte anzuordnen, um so die Zahl der Federn möglichst gering zu halten und damit auch das Gewicht des Brausekopfes. Die drei über den Umfang verteilt angeordneten Federn gewährleisten eine optimale Lage und die Nocken eine gleichmäßige Führung der Federn, die durch das Hin- und Herbewegen der Düsenplatte aus ihrer vorgegebenen Position nicht herausrutschen können. Besonders zweckmäßig ist es, wenn die besonders ausgebildete Düsenplatte mit ihren düsenförmigen Ansätzen über die Abdeckplatte hinaus vorgeschoben werden kann, um die Wasserstrahlen nicht irgendwie noch negativ zu beeinflussen. Dies ist gewährleistet, indem die Ausnehmungen in der Abdeckplatte über zum Kreismittelpunkt weisende Stege verfügen, deren freie Kanten die düsenförmigen Ansätze der Düsenplatte führend angeordnet und ausgebildet sind. Die düsenförmigen Ansätze der Düsenplatte werden somit beim Verschieben der Düsenplatte und beim Durchstoßen der Abdeckplatte sicher geführt, wobei um die düsenförmigen Ansätze eine kreisringförmige Ausnehmung verbleibt, die für das Auströmen des Wassers bei den weitere Funktionsstellungen vorgesehen ist.A stable position of the nozzle plate on the springs on the one hand and a secure reciprocation of the nozzle plate on the other hand is ensured if the springs are arranged between two perforated or nozzle circles guided by a cam assigned to the cover plate. It is expedient to arrange three springs distributed over the circumference between the cover and nozzle plate in order to keep the number of springs as low as possible and thus the weight of the shower head. The three springs distributed over the circumference ensure an optimal position and the cams ensure uniform guiding of the springs, which cannot slide out of their specified position due to the back and forth movement of the nozzle plate. It is particularly expedient if the specially designed nozzle plate with its nozzle-shaped attachments can be advanced beyond the cover plate in order not to have any negative influence on the water jets. This is ensured by the recesses in the cover plate having webs pointing towards the center of the circle, the free edges of which are arranged and designed to guide the nozzle-shaped projections of the nozzle plate. The nozzle-shaped lugs of the nozzle plate are thus reliably guided when the nozzle plate is displaced and when the cover plate is pierced, with an annular recess remaining around the nozzle-shaped lugs, which is provided for the water to flow out in the other functional positions.
Die Erfindung zeichnet sich insbesondere dadurch aus, daß eine Duscheinrichtung mit einem Brausekopf geschaffen ist, der unabhängig davon, ob er als Ein- oder Mehrfachfunktionsbrause ausgebildet ist, immer vom Wasser einwandfrei zu durchströmende Brauselöcher aufweist. Diese Brauselöcher werden im Ruhezustand durch die eingeschobenen Stifte offengehalten, so daß beim Verschieben der Düsenplatte mit ihren Brauselöchern immer ein einwandfreies Durchströmen gewährleistet ist. Die Düsenplatte wird über die Federn mechanisch in diese Ruhestellung hineingeschoben, während sie durch das einströmende und durchströmende Wasser in der Arbeitsstellung gehalten wird. Dadurch wird erreicht, daß praktisch bei jedem Benutzen der Duscheinrichtung in der Sprühstellung ein Reinigungsvorgang automatisch abläuft, wodurch eine immer funktionsfähige Duscheinrichtung bzw. ein entsprechender Brausekopf vorgehalten wird. Durch eine entsprechende Ausbildung der Wasserzuführung wird bei einer Mehrfachfunktionsduscheinrichtung das Wasser in der Sprühstellung auf die Düsenplatte geführt, während es bei weiteren Funktionen an der Düsenplatte vorbeigeführt werden kann.The invention is characterized in particular by the fact that a shower device with a shower head is created which, regardless of whether it is designed as a single or multiple function shower, always flawlessly from the water has shower holes to flow through. These shower holes are kept open by the inserted pins in the idle state, so that when the nozzle plate with its shower holes is moved, a perfect flow is always guaranteed. The nozzle plate is mechanically pushed into this rest position via the springs, while it is held in the working position by the inflowing and flowing water. It is thereby achieved that practically every time the shower device is used in the spray position, a cleaning process runs automatically, as a result of which an always functional shower device or a corresponding shower head is kept available. With a corresponding design of the water supply in a multi-function shower device, the water is guided in the spray position onto the nozzle plate, while it can be guided past the nozzle plate for other functions.

Die Duscheinrichtung (1) besteht gemäß Fig. 1 aus dem Griffteil (2), das hohl ausgebildet ist und durch das das Wasser zuströmen kann sowie aus dem Brausekopf (3). Das Griffteil (2) ist im Querschnitt in Fig. 4 wiedergegeben. Denkbar ist es, daß in dieses Griffteil (2) ein Wasserschlauch oder Rohr integriert ist. Die aus Fig. 1 und 4 ersichtliche Ausführung ist jedoch die zweckmäßigere und einfachere.1 consists of the handle part (2), which is hollow and through which the water can flow and from the shower head (3). The handle part (2) is shown in cross section in Fig. 4. It is conceivable that a water hose or tube is integrated in this handle part (2). The embodiment shown in FIGS. 1 and 4 is, however, the more expedient and simpler one.
Im Übergangsbereich zwischen Griffteil (2) und Brausekopf (3) ist ein Drehverteiler (4) bei der aus Fig. 1 ersichtlichen Ausführung angeordnet, um so über die Wasserzuführung (5) Wasser für die Sprühstellung bzw. die Softstellung einzuspeisen. Näheres hierzu ist noch weiter hinten erläutert.In the transition area between the handle part (2) and shower head (3), a rotary distributor (4) is arranged in the embodiment shown in FIG. 1, so as to feed water for the spray position or the soft position via the water supply (5). Further details are explained further below.
Die Wasserzuführung (5) ist in das Gehäuse (6) des Brausekopfes (3) integriert. Es handelt sich hier zweckmäßigerweise um ein Bauteil, das anhand der Fig. 5 und 8 näher erläutert wird, wobei eine Vielzahl von Stiften (7, 8) Teil der Wasserzuführung (5) ist oder aber mit dieser fest verbunden ist.The water supply (5) is integrated in the housing (6) of the shower head (3). This is expediently a component which is explained in more detail with reference to FIGS. 5 and 8, a large number of pins (7, 8) being part of the water supply (5) or else being firmly connected to it.
Die Stifte (7, 8), die der Wasserzuführung (5) zugeordnet sind, reichen in der Ruhestellung in eine Düsenplatte (9) hinein, die in Fig. 1 teilweise dargestellt ist. Diese Düsenplatte (9) verfügt über düsenförmige Ansätze (10), die auf der der Abdeckplatte (14) zugewandten Seite (11) über die Düsenplatte (9) vorstehen. Diese düsenförmigen Ansätze (10) reichen in die entsprechende Ausnehmungen (16) der Abdeckplatte (14) hinein, wobei die Abdeckplatte (14) den Brausekopfauslauf (15) abdeckt und absichert. In den düsenförmigen Ansätzen (10) sind die einzelnen Brauselöcher (12, 13) ausgebildet, die somit über die Stifte (7, 8) in der Ruhestellung durchstoßen werden. Wird über die Wasserzuführung (5) Wasser in den Brausekopf (3) und auf die Düsenplatte (9) geleitet, so wird diese von den Stiften (7, 8) heruntergeschoben, so daß dann die Brauselöcher (12, 13) frei werden. Wird die Wasserzufuhr abgesperrt, so drücken die Federn (17), auf die später auch noch näher eingegangen wird, die Düsenplatte (9) wieder in die Ruhestellung zurück, wo die Brauselöcher (12, 13) von den Stiften (7, 8) durchstoßen sind. Ein bleibender Reinigungserfolg ist somit gegeben.The pins (7, 8), which are assigned to the water supply (5), extend in the rest position into a nozzle plate (9), which is partially shown in FIG. 1. This nozzle plate (9) has nozzle-shaped projections (10) which protrude above the nozzle plate (9) on the side (11) facing the cover plate (14). These nozzle-shaped projections (10) extend into the corresponding recesses (16) of the cover plate (14), the cover plate (14) covering and securing the shower head spout (15). The individual shower holes (12, 13) are formed in the nozzle-shaped projections (10) and are thus pierced through the pins (7, 8) in the rest position. If water is passed through the water supply (5) into the shower head (3) and onto the nozzle plate (9), this is from the Pins (7, 8) pushed down so that the shower holes (12, 13) are then free. If the water supply is shut off, the springs (17), which will be discussed in more detail later, push the nozzle plate (9) back into the rest position, where the shower holes (12, 13) pierce through the pins (7, 8) are. A permanent cleaning success is given.
Die düsenförmigen Ansätze (10), die über die Düsenplatte (9) vorstehen, werden im Bereich der Ausnehmungen (16) der Abdeckplatte (14) über Stege (18, 19) abgestützt, wobei die freien Kanten (20) dieser Stege (18, 19) so ausgebildet sind, daß die düsenförmigen Ansätze (10) anliegen. Dadurch ergibt sich ein kreisförmiger bleibender Durchflußring für das Wasser, wenn die Softstellung eingestellt ist, wobei dann, wie anhand der Fig. 7 angezeigt ist, LUft in das Innere des Brausekopfes (3) einströmen kann, um sich mit dem Wasser zu vermischen.The nozzle-shaped projections (10) which protrude above the nozzle plate (9) are supported in the region of the recesses (16) of the cover plate (14) via webs (18, 19), the free edges (20) of these webs (18, 19) are designed so that the nozzle-shaped lugs (10) rest. This results in a circular, continuous flow ring for the water when the soft position is set, in which case, as is shown in FIG. 7, air can flow into the interior of the shower head (3) in order to mix with the water.
Fig. 2 zeigt eine Draufsicht auf die Abdeckplatte (14), wobei insbesondere die Loch- und Düsenkreise (23, 24) zu erkennen sind sowie die in den einzelnen Ausnehmungen (16) ausgebildeten Stege (18, 19). Angedeutet sind außerdem die Nocken (25), auf denen sich die Federn (17), die hier nicht wiedergegeben sind, abstützen bzw. durch diese geführt sind. Dieser Nocken (25) ist auch in Fig. 3, einem Schnitt durch die Abdeckplatte (14) zu sehen, wobei auf der gegenüberliegenden Seite der Schnitt durch Ausnehmungen (16) der Loch- bzw. Düsenkreise (23, 24) gezeigt sind.Fig. 2 shows a plan view of the cover plate (14), in particular the hole and nozzle circles (23, 24) can be seen and the webs (18, 19) formed in the individual recesses (16). Also indicated are the cams (25) on which the springs (17), which are not shown here, are supported or are guided through them. This cam (25) can also be seen in FIG. 3, a section through the cover plate (14), the section through recesses (16) of the hole or nozzle circles (23, 24) being shown on the opposite side.
Die Fig. 6 und 7 zeigen einmal die Wasserführung bei Einschalten der Sprühstellung und bei Fig. 7 der Softstellung, wozu einmal das Wasser durch den Kanal (28) und gemäß Fig. 7 durch den Kanal (29) geleitet wird. Ergänzend zeigen hierzu die Fig. 5 und 8 einen Schnitt durch die Wasserzuführung (5) bzw. das entsprechende Teil, das im Gehäuse (6) festgelegt ist. Deutlich erkennbar ist, daß das Wasser bei der Softstellung über den Umschalter (30) in den Kanal (29) geleitet wird, von wo es sich mittig an der Düsenplatte (9) vorbei auf die Abdeckplatte (14) verteilt. Mittig über das Ansaugteil (41) wird Luft angesaugt, was durch die Pfeile kenntlich gemacht ist, so daß bei dieser Softeinstellung Wasser-Luft-Gemisch durch die Ausnehmungen (16) ausströmen kann. Dieser Duschwasseraustritt ist mit (42) bezeichnet.6 and 7 show the water flow when the spray position is switched on and in FIG. 7 the soft position, for which purpose the water is passed through the channel (28) and, according to FIG. 7, through the channel (29). 5 and 8 show a section through the water supply (5) or the corresponding part, which is fixed in the housing (6). It is clearly recognizable that the water in the soft position, the switch (30) is passed into the channel (29), from where it is distributed in the middle past the nozzle plate (9) onto the cover plate (14). Air is sucked in centrally over the suction part (41), which is indicated by the arrows, so that with this soft setting water-air mixture can flow out through the recesses (16). This shower water outlet is labeled (42).
Als Umschalter (30) bzw. Drehverteiler (4) dient ein leicht mit einem Finger zu betätigendes Teil, das, wie schon erwähnt, zwischen Brausekopf (3) und Griffteil (2) angeordnet ist und mit dem Zulaufende (31) sich in der Wasserzuführung (5) bzw. auf dem Rohrendstück (32) drehen läßt. Die Führung und zugleich Drehbegrenzung übernimmt der Noppen (33), der in der Schlitzführung (34) von einer Endstellung in die andere verschoben werden kann. Die in diesen Figuren wiedergegebene Ausführung stellt eine Zweifunktionsbrause dar. Bei einer Einfunktionsbrause wird auf diesen Umschalter (30) verzichtet und das Wasser strömt ausschließlich so wie in Fig. 6 angedeutet über die Wasserzuführung (5) und den Kanal (28) auf die Düsenplatte (9).The switch (30) or rotary distributor (4) is a part that can be easily operated with a finger, which, as already mentioned, is arranged between the shower head (3) and the handle part (2) and with the inlet end (31) in the water supply (5) or on the pipe end piece (32). The knobs (33), which can be moved in the slot guide (34) from one end position to the other, take over the guiding and rotation limitation. The version shown in these figures represents a two-function shower. In the case of a single-function shower, this changeover switch (30) is dispensed with and the water flows exclusively as indicated in FIG. 6 via the water supply (5) and the channel (28) onto the nozzle plate ( 9).
Fig. 8 zeigt die Ausbildung der Stifte (7, 8). Bei der hier wiedergegebenen Ausbildung gibt es einmal die zylindrischen Endstücke (36) sowie die diese aufnehmenden Taschen (37). Die Taschen (37) sind ihrerseits direkt mit dem Bauteil, was hier als Wasserzuführung (5) bezeichnet ist, verbunden.Fig. 8 shows the formation of the pins (7, 8). In the embodiment shown here, there are the cylindrical end pieces (36) and the pockets (37) receiving them. The pockets (37) are in turn directly connected to the component, which is referred to here as water supply (5).
Fig. 9 zeigt die Düsenplatte (9) in Draufsicht und Fig. 10 im Querschnitt. Diese Düsenplatte (9) ist mit den in beiden Fluren erkennbaren düsenförmigen Ansätzen (10) ausgerüstet, wobei letztere in Fig. 11 vergrößert wiedergegeben sind. Dabei wird deutlich, daß diese Ansätze die hier nicht dargestellten Stifte (7, 8) aufnehmen, wobei durch die Form beider Teile sichergestellt ist, daß beim Auf- und Abwärtsbewegen der Düsenplatte (9) evtl. Anbackungen abgetragen werden, so daß sie dann durch die Auslaufdüsen (39, 40) nach außen mit dem Wasser weggetragen werden, so daß eine immer saubere Auslaufdüse (39, 40) zur Verfügung steht.Fig. 9 shows the nozzle plate (9) in plan view and Fig. 10 in cross section. This nozzle plate (9) is equipped with the nozzle-shaped lugs (10) recognizable in both corridors, the latter being shown enlarged in FIG. 11. It is clear that these approaches take the pins (7, 8), not shown here, whereby the shape of both parts ensures that when Moving the nozzle plate (9) up and down may cause caking, so that they are then carried away to the outside by the outlet nozzles (39, 40) with the water, so that an always clean outlet nozzle (39, 40) is available.
Alle genannten Merkmale, auch die den Zeichnungen allein zu entnehmenden, werden allein und in Kombination als erfindungswesentlich angesehen.All of the features mentioned, including those that can be seen in the drawings alone, are regarded as essential to the invention, alone and in combination.
