Description
Wasserauslaufinundstück mit einem umschaltbaren Strahlreglereinsatz. Water outlet nozzle with a switchable jet regulator insert.
Die Erfindung betrifft ein Wasserauslaufinundstück für einen Wasserhahn mit einem umschaltbaren Strahlreglereinsatz, der einen Reinigungsstrahlkanal und wenigstens eine Strömungskammer mit einer Vielzahl von Wasseraustrittsdüsen aufweist, wobei wenigstens eine Einströmöffnung der Strömungskammer mit wenigstens einem in sei¬ ne Schließstellung vorgespannten Ventil steuerbar ist, derart, dass vom anströmenden Wasser das Ventil von einem vorgebbaren Staudruck des Wassers offenbar ist.The invention relates to a water outlet nozzle for a faucet with a switchable jet regulator insert, which has a cleaning jet channel and at least one flow chamber with a multiplicity of water outlet nozzles, wherein at least one inlet opening of the flow chamber can be controlled with at least one valve prestressed in its closed position such that oncoming water the valve is obviously from a predeterminable back pressure of the water.
Ein Wasserauslaufinundstück der Eingangs genannten Gattung ist aus der DE 44 36 139 Al bekannt. Hier sind die Einströmöffnungen von vier Strömungskammern je¬ weils mit einem Ventil in der Grundstellung verschlossen. Bei einer Wasserzufuhr fließt das Wasser zunächst ausschließlich durch einen fest im Zentrum des Strahlreg¬ lereinsatzes angeordneten Reinigungsstrahlkanal. Sobald die Wassermenge vergrößert wird und einen bestimmten Wert übersteigt, werden die Ventile automatisch durch den Staudruck des Wassers nacheinander geöffnet und Wasser strömt zusätzlich den Strö¬ mungskammern zu und tritt durch eine Vielzahl von Wasseraustrittsöffnungen als auf¬ geweiteter Wasserstrahl aus dem Wasserauslaufinundstück aus. Wird die Wassermen¬ ge wieder verkleinert, so schließen sich die Ventile nacheinander automatisch wieder und es wird nur noch der Reinigungsstrahlkanal mit Wasser versorgt. Die vier Ventile weisen jeweils eine Dichtung und eine Ventilfeder auf, so dass dieser Strahlregler kon¬ struktiv sehr aufwändig, groß und darüber hinaus wegen der Vielzahl von beweglichen Teilen auch sehr verschleißanfällig ist. Außerdem kann ein handelsüblicher Strahlreg¬ ler nicht ohne Aufwand gegen diesen großen Strahlregler ausgetauscht werden. Im Übrigen kann das Ventil nicht von Außen geschlossen werden, falls es einmal in seiner Öffnungsposition festhängt.A Wasserauslaufinundstück the input named genus is known from DE 44 36 139 Al. Here, the inflow openings of four flow chambers are each closed with a valve in the basic position. When water is supplied, the water initially flows exclusively through a cleaning jet channel which is fixedly arranged in the center of the jet regulator insert. As soon as the amount of water is increased and exceeds a certain value, the valves are opened automatically one after the other by the ram pressure of the water and water additionally flows to the flow chambers and exits through a multiplicity of water outlet openings as an expanded water jet out of the water outlet inlet. If the quantity of water is reduced again, then the valves automatically close one after the other and only the cleaning jet channel is supplied with water. The four valves each have a seal and a valve spring, so that this jet regulator is structurally very complex, large and, in addition, very susceptible to wear due to the large number of moving parts. In addition, a commercial Strahlreg¬ ler can not be exchanged without effort against this large jet regulator. Incidentally, the valve can not be closed from the outside, if it once stuck in its open position.
Aus der DE 23 20 624 C2 ist ein weiterer Strahlregler bekannt, bei dem durch eine Drehbetätigung des Gehäuses wechselweise zwei Ventilsitze abgesperrt werden, wo¬ durch zwischen einem unbelüfteten ringförmigen Sprühstrahl und einem innerhalb des
Sprühstrahls mittig austretenden belüfteten Wasserstrahl umgeschaltet wird. Die Um- schaltung erfolgt hier ausschließlich manuell.From DE 23 20 624 C2, a further jet regulator is known, in which alternately two valve seats are shut off by a rotary actuation of the housing, wo¬ by between an unvented annular spray and one within the Spray jet is switched in the middle emerging aerated water jet. The changeover is done exclusively manually.
Aufgabe der Erfindung ist es, ein Wasserauslaufinundstück mit einem Strahlreglerein¬ satz der eingangs genannten Art so auszugestalten, dass der Strahlreglereinsatz ein automatisches Umschalten zwischen einem scharfen, gebündelten Reinigungsstrahl, wie er beispielsweise zur Reinigung eines Rasierers erforderlich ist, und einem nor¬ malen, aufgeweiteten, insbesondere belüfteten Wasserstrahl, einem Soft - Strahl, mit möglichst wenig Bauteilen technisch einfach und verschleißarm ermöglicht. Außerdem sollen das Wasserauslaufinundstück und der Strahlreglereinsatz universell ohne jeden Aufwand gegen ein Standard - Wasserauslaufmundstück beziehungsweise einen Stan¬ dard - Strahlreglereinsatz austauschbar sein.The object of the invention is to design a water outlet nozzle with a jet regulator insert of the type mentioned above such that the jet regulator insert automatically switches between a sharp, bundled cleaning jet, as required, for example, for cleaning a razor, and a normal, widened one , in particular a ventilated water jet, a soft jet, with as few components as possible in a technically simple and wear - resistant manner. In addition, the water outlet nozzle and the jet regulator insert should be universally exchangeable without any effort against a standard water outlet nozzle or a standard jet regulator insert.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Ventil einen in Wasser¬ strömungsrichtung axial verschiebbaren Ventilkolben mit einem Ventilteller aufweist und der Reinigungsstrahlkanal im hohlen Ventilkolben verläuft und der Ventilteller wenigstens eine Wassereintrittsöffnung zu dem Reinigungsstrahlkanal aufweist.This object is achieved according to the invention in that the valve has a valve piston which can be axially displaced in the direction of flow of water with a valve disk and the cleaning jet channel runs in the hollow valve piston and the valve disk has at least one water inlet opening to the cleaning jet channel.
Erfindungsgemäß wird durch Vergrößerung des Staudrucks des Wassers auf den Ven¬ tilteller der gesamte Reinigungsstrahlkanal in Wasseraustrittsrichtung verschoben und das Ventil geöffnet, so dass zusätzlich zum Reinigungsstrahl ein aus mehreren Einzel¬ strahlen zusammengesetzter Soft - Strahl aus den Wasseraustrittsdüsen austritt. Der Reinigungsstrahlkanal bildet hier also mit dem Ventil eine Einheit, so dass der kon¬ struktive Aufwand und auch die Verschleißanfalligkeit deutlich reduziert wird.According to the invention, the entire cleaning jet channel is displaced in the water outlet direction by enlarging the dynamic pressure of the water on the tilting plate and the valve is opened so that, in addition to the cleaning jet, a soft jet composed of several individual beams emerges from the water outlet nozzles. The cleaning jet channel thus forms a unit with the valve, so that the constructive effort and the wear susceptibility are significantly reduced.
Bei einer vorteilhaften Ausfuhrungsform ist der Strahlreglereinsatz in einer standardi¬ sierten Schraubhülse angeordnet. Dies hat den großen Vorteil, dass das erfindungsge¬ mäße Wasserauslaufmundstück oder lediglich der Strahlregler universell ohne jeden Aufwand gegen ein Wasserauslaufinundstück mit einem Standard - Strahlregler bezie¬ hungsweise einen Standard - Strahlregler austauschbar ist.
Zweckmäßigerweise kann der Ventilkolben in der Mitte des im Wesentlichen symme¬ trisch aufgebauten Strahlreglereinsatzes angeordnet sein, wodurch sowohl die Stabili¬ tät vergrößert, als auch der konstruktive Aufwand weiter deutlich reduziert wird.In an advantageous embodiment, the jet regulator insert is arranged in a standardized screwed sleeve. This has the great advantage that the erfindungsge¬ Permitted water outlet mouthpiece or only the jet regulator universally without any effort against a Wasserauslaufinundstück with a standard - be¬ regulators behaved as a standard - jet regulator. Conveniently, the valve piston can be arranged in the middle of the essentially symmetrically constructed jet regulator insert, which increases both the stability and also significantly reduces the constructive effort.
Besonders vorteilhaft ist es, wenn der Ventilkolben bei geöffnetem Ventil zu einem Teil wasseraustrittsseitig aus dem Wasserauslauf mundstück herausragt. So kann der Ventilkolben manuell, beispielsweise mit einem Finger, in das Wasserauslaufmund¬ stück zurück gedrückt werden, falls es wegen Verschmutzungen und/oder Kalkablage¬ rungen in seiner Öffnungsposition festhängt.It is particularly advantageous if the valve piston protrudes mouthpiece when the valve is open to a part of the water outlet side of the water outlet. Thus, the valve piston can be pushed back manually, for example with a finger, into the water outlet mouthpiece if it is stuck in its opening position due to soiling and / or calcium deposits.

winde 6 aufweist. Die in Figur 4 von der Seite dargestellte Schrauhhülse 3 mit dem Außengewinde 6 entspricht in seinen Ausmaßen einem handelsüblichen, standardi¬ sierten Wasserauslaufmundstück, so dass letzteres oder lediglich deren Strahlreglerein¬ satz ohne weiteres gegen das Wasserauslaufmundstück 1 beziehungsweise den Strahl- reglereinsatz 2 austauschbar ist.The screw sleeve 3 is a hollow cylinder which is open at its two end faces, the water inlet side 4, in FIG. 1 at the top, an outer face on its outer lateral surface 5. wind 6 has. The Schrauhhülse 3 shown in Figure 4 from the side with the external thread 6 corresponds in its dimensions to a standard, standardized water outlet nozzle, so that the latter or only the Strahlreglerein¬ rate is readily exchangeable against the water outlet nozzle 1 and the jet regulator insert 2.
In einem wasseraustrittseitigen Bereich 7 der Schraubhülse 3 sind zwei parallele ebene Schlüsselflächen 8 für die Gabeln eines Gabelschlüssel zur Montage beziehungsweise Demontage des Wasserauslaufmundstücks 1 vorgesehen.In a water outlet side region 7 of the screw 3, two parallel flat key surfaces 8 are provided for the forks of a fork wrench for mounting or dismounting the water outlet nozzle 1.
Der Strahlreglereinsatz 2 umfasst einen Strahlreglerkörper 9, welcher in seinen Au- ßenmaßen den Innemaßen der Schraubhülse 3 , also denen eines herkömmlichen Strahlreglereinsatzes entspricht und von oben in diese eingesetzt ist. Damit er nicht nach unten durchrutschen kann, weist der Strahlreglerkörper 9 entlang seines oberen Randes einen nach außen überstehenden umlaufenden Kragen 10 auf, der auf einer komplementären Stufe 11 an der Innenmantelfläche der Schraubhülse 3 aufsetzt.The jet regulator insert 2 comprises a jet regulator body 9, which in its outer dimensions corresponds to the internal dimensions of the threaded sleeve 3, that is to say that of a conventional jet regulator insert, and is inserted from above into this.

Der Strahlreglerkörper 9 ist oben mit einem ebenen ringförmigen Deckel 13 verschlos- sen, der in seiner Mitte eine Wassereintrittsöffnung 14 aufweist. Der Deckel 13 schließt mit dem Kragen 10 nach oben bündig ab, so dass die Flachdichtung 12 zu¬ sätzlich den Bereich zwischen dem Kragen 10 und dem Deckel 13 abdichtet.The jet regulator body 9 is closed at the top with a flat annular cover 13, which has a water inlet opening 14 in its center. The cover 13 terminates flush with the collar 10 upwards, so that the flat seal 12 additionally seals the region between the collar 10 and the cover 13.
Über der Wassereintrittsöffnung 14 ist auf dem Deckel 13 ein kegelmantelförmiges Sieb 15 abnehmbar angeordnet, dessen Spitze nach oben gerichtet ist. Das Sieb 15 auf dem Deckel 13 des Wasserauslaufmundstücks 1 ist in Figur 3 in der Draufsicht darge¬ stellt.About the water inlet opening 14, a cone-shaped screen 15 is removably disposed on the lid 13, the tip of which is directed upwards. The sieve 15 on the lid 13 of the water outlet mouthpiece 1 is shown in FIG. 3 in plan view.
Die Wasseraustrittsseite 7 des Strahlreglerkörpers 9 wird durch einen Boden 16 abge¬ schlossen, in dem in der Unteransicht in Figur 5 eine Vielzahl von durchgängigen in-
neren beziehungsweise äußeren Wasseraustrittsdüsen 17 entlang von zwei konzentri¬ schen Kreisen angeordnet sind. In der Mitte weist der Boden 16 eine kreisförmige Durchgangsbohrung 18 auf, durch den ein hohler Ventilkolben 19 eines Ventils 20 gerührt ist, mit dem in weiter unten erläuterter Weise unterhalb der Wassereintrittsöff- nung 14 des Deckels 13 liegende Einströmöfßiungen 21 zu inneren und äußeren Strö- mungskammern 22, 23 des Strahkeglerkörpers 9 gesteuert werden.The water outlet side 7 of the jet regulator body 9 is closed by a bottom 16 in which, in the bottom view in FIG. neren or outer water outlet nozzles 17 along two concentri¬ rule circles are arranged. In the middle, the bottom 16 has a circular through-bore 18, through which a hollow valve piston 19 of a valve 20 is stirred, with the inflow openings 21 lying below the water inlet opening 14 of the cover 13 to inner and outer streams, as explained in more detail below. mung chambers 22, 23 of the Strahkeglerkörpers 9 are controlled.

The cleaning jet channel 34 passes through the valve plate 30 and the valve piston 19 through to the cleaning jet outlet 18 in the bottom 16 of the jet regulator body. 9
Wird die Wasserzufuhr in an sich bekannter Weise an dem nicht dargestellten, mit dem Wasserauslaufmundstück 1 verbunden Ventil geöffnet, so strömt Wasser 35 was- sereintrittsseitig 4 in Figur 1 von oben durch dass Sieb 15 hindurch zunächst lediglich durch den Reinigungsstrahlkanal 34 im Ventilkolben 19 hindurch und tritt wasseraus- trittseitig als ein einziger, scharfer Reinigungsstrahl 36 aus dem Wasserauslaufmund¬ stück 1 aus.If the water supply is opened in a manner known per se to the valve, not shown, connected to the water outlet mouthpiece 1, water 35 flows through the sieve 15 first through the sieve 15 only through the cleaning jet channel 34 in the valve piston 19 emerges on the water outlet side as a single, sharp cleaning jet 36 from the water outlet mouthpiece 1.
Wird die Wasserzufuhr weiter vergrößert, so führt die Vergrößerung des Staudrucks des einströmenden Wassers an dem Ventilteller 30 dazu, dass ab einer bestimmten Wassermenge die Öffnungskraft für das Ventil 20 von oben größer ist als die Schlie߬ kraft der Druckfeder 28, so dass endlich der Ventilkolben 19 mitsamt dem darin ange¬ ordneten Reinigungstrahlkanal 34 und dem Ventilteller 30 in Figur 2 nach unten ge¬ schoben wird und das Ventil 20 geöffnet wird. Der Ventilkolben 19 ragt dann zu ei¬ nem Teil unten aus dem Boden 16 des Strahlreglerkörpers 9 heraus.If the water supply is further increased, the increase in the back pressure of the inflowing water on the valve disk 30 causes the opening force for the valve 20 from above to be greater than the closing force of the compression spring 28, so that finally the valve piston starts at a certain amount of water 19, together with the cleaning jet channel 34 arranged therein and the valve disk 30 in FIG. 2, is pushed downwards and the valve 20 is opened. The valve piston 19 then projects outwards from the bottom 16 of the jet regulator body 9 to a lower part.
Durch die Öffnung des Ventils 20 werden die Einströmöffhungen 21 freigegeben, Wasser kann den Strömungskammern 22, 23 zuströmen, wo es mit Luft angereichert wird, und aus diesen heraus durch die Wasseraustrittsdüsen 17 hindurch aus dem Bo¬ den 16 austreten. Darüber hinaus fließt weiterhin Wasser durch den zentralen Reini¬ gungstrahlkanal 36, so dass insgesamt ein aufgeweitetes Strahlbild, also ein „Soft - Strahl" 37 mit dem zentralen Reinigungsstrahl 36, entsteht.Through the opening of the valve 20, the Einströmöffhungen 21 are released, water can flow to the flow chambers 22, 23, where it is enriched with air, and out of these through the water outlet nozzles 17 from the Bo¬ 16 exit. In addition, water continues to flow through the central cleaning jet channel 36, so that overall an expanded jet pattern, that is to say a "soft jet" 37 with the central cleaning jet 36, arises.
Wird die Wasserzufuhr reduziert, so schließt das Ventil 20 automatisch, indem der Ventilteller 30 durch die Vorspannung der Druckfeder 28 wieder an den Ventilsitz 31 gepresst wird.
Falls der Ventilkolben 19 beispielsweise wegen Verschmutzungen oder Kalkablage¬ rungen einmal in seiner Öf&ungsposition festhängen sollte, kann er auch von außen manuell nach oben geschoben werden. Es versteht sich, dass das Wasserauslauimund- stück 1 zu Wartungs- und/oder Reparaturzwecken vollständig zerlegbar sein kann, und alle beweglichen Teile und Dichtungen austauschbar sind.
If the water supply is reduced, then the valve 20 closes automatically by the valve disk 30 is pressed by the bias of the compression spring 28 back to the valve seat 31. If the valve piston 19 should, for example, become stuck in its opening position due to soiling or calcium deposits, it can also be manually pushed upwards from the outside. It is understood that the Wasserauslauimund- piece 1 for maintenance and / or repair purposes can be completely dismantled, and all moving parts and seals are interchangeable.
