Definitions
- the invention relates to a effervescent spray outlet device having a jet disk which has at least one jet disk opening, and to a jet outlet element arranged in the jet disk opening, and to a shower with such a shower jet effervescing device.
- a sanitary shower head such as a head, hand or side shower, or a shower at the outlet of a sanitary water dispenser or mixer tap for a bathtub or a sink or sink, act as a kitchen shower for a kitchen sink.
- Effervescent spray exit devices of this type are known in particular for sanitary showers variously.
- Such is in the published patent application EP 2 684 610 A1 discloses a shower with such a spray jet outlet device, in which the jet disk has a plurality of jet disk openings and the jet outlet elements are formed from a hollow cylindrical elastomeric material with a continuous hollow channel as a beam exit opening and formed on a common, abutting the inside of the jet disk jet exit plate.
- Such cylindrical jet outlet elements made of an elastomer material are also referred to as a jet outlet nipple or shortly as a nipple.
- the effervescent spray outlet device multi-channel jet outlet units each having at least two fluid-separated outlet channels.
- the various outlet channels of the respective jet outlet unit open on the inlet side into separate fluid outlet chambers, so that the fluid can selectively and selectively be supplied to one of the outlet channels, for example, to provide different spray jet types.
- Hollow-cylindrical jet outlet elements or nipples of elastomer material function as jet exit units, wherein the exit channels extend continuously from one to the other cylinder end side, for example parallel next to each other or in a coaxial arrangement.
- the nipples are preferably formed integrally with and on a jet exit plate of the elastomeric material, which is arranged on the inside of the jet disk.
- the patent US 5,246,301 discloses a brush-type showerhead with brush pins which function as single-channel or dual-channel jet outlet elements.
- the jet outlet pegs have a cylindrical, conically tapering shape and, in a single-channel design, have an outlet channel extending longitudinally through the peg or an outlet channel opening out on the cylinder side wall.
- the respective pin In two-channel design, has a longitudinally and centrally passing outlet channel and an inlet side of this central outlet channel extending and opening out at the pin side wall outlet channel.
- effervescent spray outlet device has an existing elastic material, annular bottom part, the outlet side is provided with water passage openings and rests with its side walls against side walls of a corresponding annular channel 108 of a shower head housing and is thereby fixed in the shower head.
- the bottom portion can bulge outward depending on the water pressure, to promote lime removal in the region of the water passage openings.
- Effervescent spray exit devices are designed especially for sanitary applications typically for providing one or more selectively selectable Effervescent spray types, for example, to provide a massage jet, a normal jet, a jet stream or a needle jet or fine jet.
- fine / needle jet it is known to provide a jet disk with comparatively small jet disk openings, which function as jet outlet openings of the shower and accordingly as fine jet openings.
- a thin metal disk into which the fine jet openings can be introduced relatively easily in terms of production technology serves as a jet disk. Due to their relatively low passage cross-section, these fine jet openings are very sensitive to clogging due to dirt particles and calcification, which is why effervescent jet exit devices of this type have already been proposed with exchangeable metallic jet disc.
- the invention is based on the technical problem of providing a spray jet outlet device of the type mentioned, which can be produced and operated with relatively little effort and allows a functionally reliable fine jet shower with comparatively fine, if necessary, individual jets, which is relatively insensitive to clogging by dirt particles and calcification.
- the jet outlet element is pot-shaped with an exit-side bottom, a side wall and a hollow chamber bounded by the bottom and the side wall.
- the jet outlet element is arranged pointing with its bottom in the beam exit direction in the associated jet disk opening and thereby preferably held on the jet disk and has in its bottom a plurality of spaced apart, extending through the bottom extending fine jet openings. This creates the prerequisite for being able to provide a very fine spray jet, if necessary, which can be, in particular, a fog-like fine spray jet.
- the bottom and the side wall of the jet outlet element are made of an elastic material, preferably in one piece of the same elastic material.
- the entire jet outlet element can be made in one piece from the elastic material.
- the elastic material may in particular be an elastomeric material, such as a conventional silicone-based elastomeric material.
- the jet outlet element is designed such that it buckles with its bottom and / or its side wall as a function of a pending in the hollow chamber fluid operating pressure. Under fluid operating pressure is to be understood in the normal use of the shower pressure of the shower supplied fluid. This deformation of the jet outlet element by the fluid operating pressure occurring during operation of the effervescent spray outlet device advantageously prevents functional failures or functional restrictions due to dirt particles and calcification.
- this effervescent spray outlet device can be produced and operated reliably with relatively little effort.
- the fine jet openings can be introduced into the bottom of the jet outlet element with a relatively small passage or exit cross section. Feed effervescent fluid enters the hollow chamber of the pot-shaped jet outlet element and can escape from there through the fine jet openings as a fine / needle jet from the effervescent spray outlet device.
- the cup-shaped design of the jet outlet element can keep the susceptibility of the spray jet outlet device for blockages of the fine jet openings due to accumulating dirt / lime particles low and facilitate the removal of any adhering dirt / lime particles.
- the effervescent spray outlet device can have any number of such jet outlet elements corresponding to the number of associated jet disk openings, preferably a plurality of jet exit elements uniformly distributed over the extent of an associated jet disk surface.
- the one or more jet outlet elements can terminate flush with the jet disk with its / their bottom or be slightly set back relative to the outside thereof or preferably protrude outward beyond the jet disk. In the latter case, it may be further preferred if the Jet exit element also still projects with an adjoining the bottom region of its side wall over the jet disk to the outside. In corresponding implementations, the jet outlet element protrudes outwards beyond the jet disk with more than half the axial length of its side wall. This favors the fluid pressure dependent deformation of the jet outlet element and in particular its side wall unhindered by the jet disk.
- the fine jet openings are made with a passage cross-section of in each case at most 0.2 mm 2 , in particular of in each case at most 0.1 mm 2 .
- This dimensioning measure makes it possible to provide a correspondingly fine spray jet.
- an outer diameter of the bottom and the side wall of the jet outlet element is at most 10 mm, in particular at most 6 mm, in corresponding applications also only at most 5 mm or at most 4 mm. Also, this dimensioning measure can be beneficial to achieve a very fine spray jet.
- the bottom of the jet outlet element has at least three and at most ten fine jet openings. This dimensioning measure can also be favorable in terms of manufacturing technology and advantageous in terms of the achievable shower spray characteristic.
- the jet outlet element is arranged parallel to the beam exit direction between a retracted end position and a Wegwegten end position translationally movable in the jet disk opening, which is in pending in the hollow chamber fluid operating pressure in the réellewegten end position and is located in the retracted end position in the absence of fluid operating pressure in the hollow chamber ,
- This can have functional advantages in many cases.
- the jet outlet element can be completely retracted into the jet disk opening, for example, with this flush outside or be withdrawn against this.
- the jet outlet element is retracted in its retracted end position only to a rear part in the jet disk opening.
- the jet outlet element For example, at least with its bottom outside of the jet disk opening, in corresponding embodiments additionally with a smaller or alternatively with a larger part of its side wall. This favors the bulging deformation of the jet outlet element, especially of its bottom and / or its side wall, under the effect of the fluid operating pressure in the hollow chamber.
- the jet outlet element is guided so as to be movable in translation in the jet disk opening or, alternatively, held with a rear region on the jet disk or shower part upstream of the spray disk so that it can advance with its bottom and preferably also its side wall in a fluid pressure-dependent manner, eg elastically.
- the jet outlet element is arranged elastically restoring in the direction of the retracted end position, so that it automatically moves back into thetechnischbewegte end position when the fluid pressure decreases.
- the jet outlet element is designed such that based on a non-pressurized state, the diameter of its side wall and / or a passage cross section of its fine jet openings by the buckling of the bottom and / or the side wall at a fluid operating pressure of 0.5bar is increased by at least 3% / are and / or increased by at least 8% at a fluid operating pressure of 1 bar and / or increased by at least 12% at a fluid operating pressure of 1.5 bar. It turns out that this system design for the jet outlet element results in a sufficiently good protection against rapid clogging by dirt particles and / or limescale deposits, especially when used in sanitary showers, where the water operating pressure is typically in this range.
- the bottom and the side wall of the jet outlet element made of an elastomeric material having a Shore A hardness of at most 75, in particular of at most 40th It is found that with this system design of the jet outlet element also the bulging deformation of the jet outlet element in dependence supported by the fluid operating pressure in a favorable manner.
- the jet outlet element on a radially projecting from the side wall retaining shoulder. This can be used to the jet outlet element to keep safe at the jet disk or an adjacent device.
- the jet outlet element has axially projecting spacers on its entry-side front end. This can be used to position the jet exit element between the jet disk and a distance from the inside of the jet disk, e.g. To hold plate-shaped or disc-shaped housing or partition wall of the shower, against which the jet outlet element comes with its axially projecting spacer to the plant. It can be formed between the jet disk and the housing or intermediate wall, a fluid outlet chamber, which is supplied with the effervescent fluid and from which the effervescent fluid can get into the hollow chamber of the jet outlet element.

- the oblique angle can be the same for all fine jet openings 7 or alternatively for at least two fine jet openings 7 different.
- one or more fine jet openings may be provided in a region of the side wall 6b of the jet outlet element 6 projecting beyond the jet disk 4.
- the individual jet outlet elements 6 in the variants of the Fig. 4 to 9 made of an elastic material, for example a silicone-based elastomeric material.
- an elastic material for example a silicone-based elastomeric material.
- the jet outlet element 6 is made in one piece as a component of an elastic material.
- the jet outlet element 6 is adapted to buckle with its bottom 6a and / or its side wall 6b depending on a pending in the hollow chamber 6c pressure of the spray supplied fluid in operation. This will be described below with reference to the embodiment of Fig. 5 to 7 and the others FIGS. 10 to 17 explained in more detail.
- the jet outlet element 6 in the pressureless state, ie in the state when no fluid pressure in the hollow chamber 6c is applied. It has in the examples shown a circular cross section, in alternative embodiments, it has a different cross section, for example, an oval or polygonal cross section.
- the jet outlet element 6 is preferably manufactured so that in this unpressurized state its fine-beam openings 7 have a passage cross-section of each of more than about 0.2 mm 2, in particular more than about 0.1 mm 2.
- the jet outlet element 6 is preferably designed so that in the pressureless state its outside diameter in the region of the bottom 6a and the side wall 6b is at most approximately 10 mm, in particular at most approximately 6 mm, eg only approximately 4 mm ,
- the 10 and 11 illustrate the jet outlet element 6 in an operating state, in which in the hollow chamber 6c and in an associated fluid supply a Operating pressure of the supplied fluid, such as water, of about 0.5 bar prevails. It can be seen that the base 6a and the side wall 6b of the jet outlet element 6 already begin to buckle slightly due to the applied fluid pressure compared with the unpressurised state, wherein the curvature forms a diameter D of the side wall 6b and / or a passage cross-section A of the fine jet openings 7 is typically already increased by at least about 3% compared to the non-pressurized state.
- a Operating pressure of the supplied fluid such as water
- the passage cross section A of the fine jet openings 7 begins to change from its circular shape in the pressureless state into an oval shape widening in the circumferential direction of the jet outlet element 6.
- FIGS. 12 and 13 show the proportions according to the 10 and 11 for a fluid operating pressure of about 1bar.
- Out Fig. 12 It can be seen that now the cross sections of the fine jet openings 7 are already noticeably oval, and out Fig. 13 It can be seen that the side wall 6c has bulged further in its diameter D and also the bottom 6a reinforced to the outside, ie in Fig. 13 down, arching.
- a percentage increase of the diameter D and of the passage cross-section A of the fine jet openings 7 by approximately 11% to 13% was observed for this fluid pressure of approximately 1 bar.
- the jet exit element 6 is preferably designed so that the said percentage increase for these two parameters at 1 bar is at least about 8%.
- FIGS. 14 and 15 show the proportions according to the FIGS. 12 and 13 at further increased to a value of about 1.5 bar fluid operating pressure. How out Fig. 14 to recognize, the fine jet openings 7 have now noticeably expanded oval. In the case of said practical example, an increase in the passage cross-section A at this pressure of about 1.5 bar was found to be slightly more than 80% compared to the unpressurised state. Out Fig. 15 It can be seen that the side wall 6b further bulges with its diameter D, that is enlarged, and also the bottom 6a further outwards, ie in Fig. 15 down, has bulged. The latter has the mentioned oval expansion of the fine jet openings 7 result.
- FIGS. 16 and 17 illustrate the conditions for the condition at the fluid pressure of about 1.5 bar according to the FIGS. 14 and 15 Comparing with the depressurized state according to Fig. 5 to 7 in a common bottom view or side view.
- Fig. 16 it is clear that and how an unpressurized, circular passage cross section A 0 of the fine-beam openings 7 6 oval widened passage cross-section A 15 widens in a circumferential direction of the jet exit element.
- Fig. 17 It is shown how an unpressurized diameter value D 0 of the side wall 6b increases in an arched diameter value D 15 at the fluid pressure value of 1.5 bar.
- the system design for the buckling behavior of the jet exit element 6 is determined primarily by appropriate choice of wall thickness for the bottom 6a and side wall 6b and the ratio of axial length to diameter and elasticity of the material used, such as the shore Hardness of a used elastomeric material. Furthermore, it may be important whether and with what proportion of its axial length the jet outlet elements 6 protrude beyond the jet disk 4. Depending on requirements, the respective jet outlet element can be designed so that bulges in pending fluid pressure only its bottom or only its side wall or, as explained above, arch its bottom and its side wall.
- the jet outlet element 6 remains its surface by the operation of the shower in motion, as changes in operation, the fluid pressure, in particular between the unpressurized state when the shower and the respectively given normal operating pressure of the fluid in the active effervescent operation.
- This constant or recurrent movement of the surface of the jet outlet element 6 complicates or prevents permanent deposits of dirt and lime particles.
- due to this breathing of the jet outlet element 6, possibly deposited dirt / limescale deposits usually be automatically detached or blasted off by the operation of the shower.
- the fine jet openings 7 in in Fig. 18 shown unpressurized state in the radial direction of the jet outlet element 6 oval broadened cross-section.
- the Fig. 19 shows these fine jet openings 7 at a fluid operating pressure of about 0.5 bar.
- the oval shape of the fine jet openings 7 in this case already begins to weaken somewhat in the direction of a circular cross-sectional shape by using the already mentioned broadening of the fine jet openings 7 in the circumferential direction of the jet outlet element 6.
- Fig. 20 shows the jet outlet element 6 in the state at a fluid operating pressure of about 1.0 bar.
- Fig. 21 shows the state at a fluid operating pressure of about 1.5 bar.
- the fine jet openings 7 have now widened in the circumferential direction of the jet outlet element 6 in such a way that they have an approximately circular cross-section.
- a shower jet will be provided which is generated by the fine jet openings 7 with a more oval or a more circular cross-section.
- the respective jet outlet element is axially immovable and guided laterally in the associated jet disk opening.

Description
Die Erfindung bezieht sich auf eine Brausestrahlaustrittsvorrichtung mit einer Strahlscheibe, die wenigstens eine Strahlscheibenöffnung aufweist, und mit einem in der Strahlscheibenöffnung angeordneten Strahlaustrittselement sowie auf eine Brause mit einer solchen Brausestrahlaustrittsvorrichtung. Hierbei kann es sich z.B. um eine sanitäre Duschbrause, wie eine Kopf-, Hand- oder Seitenbrause, oder um eine Brause am Austritt einer sanitären Wasserabgabe- bzw. Mischerarmatur für eine Badewanne oder ein Waschbecken oder Spülbecken, wie eine Küchenbrause für eine Küchenspüle, handeln.The invention relates to a effervescent spray outlet device having a jet disk which has at least one jet disk opening, and to a jet outlet element arranged in the jet disk opening, and to a shower with such a shower jet effervescing device. This may be e.g. a sanitary shower head, such as a head, hand or side shower, or a shower at the outlet of a sanitary water dispenser or mixer tap for a bathtub or a sink or sink, act as a kitchen shower for a kitchen sink.
Brausestrahlaustrittsvorrichtungen dieser Art sind insbesondere für Sanitärbrausen verschiedentlich bekannt. So ist in der Offenlegungsschrift
Bei einer weiteren, in der Offenlegungsschrift
Die Patentschrift
Eine in der Offenlegungsschrift
Brausestrahlaustrittsvorrichtungen werden speziell bei sanitären Anwendungen typischerweise zur Bereitstellung einer oder mehrerer, selektiv anwählbarer Brausestrahlarten ausgelegt, z.B. zur Bereitstellung eines Massagestrahls, eines Normalstrahls, eines Schwallstrahls oder eines Nadelstrahls bzw. Feinstrahls. Für einen solchen sogenannten Fein-/Nadelstrahl ist es bekannt, eine Strahlscheibe mit vergleichsweise kleinen Strahlscheibenöffnungen vorzusehen, die als Strahlaustrittsöffnungen der Brause und dementsprechend als Feinstrahlöffnungen fungieren. Herkömmlicherweise dient dazu eine dünne Metallscheibe, in welche die Feinstrahlöffnungen fertigungstechnisch relativ einfach eingebracht werden können, als Strahlscheibe. Aufgrund ihres relativ geringen Durchtrittsquerschnitts sind diese Feinstrahlöffnungen sehr empfindlich gegenüber Verstopfung durch Schmutzpartikel und Verkalkung, weshalb bereits Brausestrahlaustrittsvorrichtungen dieser Art mit wechselbarer metallischer Strahlscheibe vorgeschlagen wurden.Effervescent spray exit devices are designed especially for sanitary applications typically for providing one or more selectively selectable Effervescent spray types, for example, to provide a massage jet, a normal jet, a jet stream or a needle jet or fine jet. For such a so-called fine / needle jet, it is known to provide a jet disk with comparatively small jet disk openings, which function as jet outlet openings of the shower and accordingly as fine jet openings. Conventionally, a thin metal disk into which the fine jet openings can be introduced relatively easily in terms of production technology serves as a jet disk. Due to their relatively low passage cross-section, these fine jet openings are very sensitive to clogging due to dirt particles and calcification, which is why effervescent jet exit devices of this type have already been proposed with exchangeable metallic jet disc.
Der Erfindung liegt als technisches Problem die Bereitstellung einer Brausestrahlaustrittsvorrichtung der eingangs genannten Art zugrunde, die mit relativ geringem Aufwand herstellbar und betreibbar ist und einen funktionssicheren Feinstrahl-Brausebetrieb mit bei Bedarf vergleichsweise feinen Einzelstrahlen ermöglicht, der relativ unempfindlich gegenüber Verstopfung durch Schmutzpartikel und Verkalkung ist.The invention is based on the technical problem of providing a spray jet outlet device of the type mentioned, which can be produced and operated with relatively little effort and allows a functionally reliable fine jet shower with comparatively fine, if necessary, individual jets, which is relatively insensitive to clogging by dirt particles and calcification.
Die Erfindung löst dieses Problem durch die Bereitstellung einer Brausestrahlaustrittsvorrichtung mit den Merkmalen des Anspruchs 1. Bei dieser Brausestrahlaustrittsvorrichtung ist das Strahlaustrittselement topfförmig mit einem austrittsseitigen Boden, einer Seitenwandung und einer vom Boden und der Seitenwandung begrenzten Hohlkammer ausgebildet. Das Strahlaustrittselement ist mit seinem Boden in Strahlaustrittsrichtung weisend in der zugehörigen Strahlscheibenöffnung angeordnet und dabei vorzugsweise an der Strahlscheibe gehalten und weist in seinem Boden eine Mehrzahl voneinander beabstandeter, sich durch den Boden hindurch erstreckender Feinstrahlöffnungen auf. Dies schafft die Voraussetzung, bei Bedarf einen sehr feinen Brausestrahl bereitstellen zu können, bei dem es sich insbesondere um einen nebelartig feinen Brausestrahl handeln kann.The invention solves this problem by providing a effervescent spray outlet device having the features of
Der Boden und die Seitenwandung des Strahlaustrittselements bestehen aus einem elastischen Material, vorzugsweise einteilig aus dem gleichen elastischen Material. Optional kann das gesamte Strahlaustrittselement einteilig aus dem elastischen Material gefertigt sein. Das elastische Material kann insbesondere ein elastomeres Material sein, wie z.B. ein herkömmliches silikonbasiertes Elastomermaterial. Das Strahlaustrittselement ist so ausgelegt, dass es sich mit seinem Boden und/oder seiner Seitenwandung abhängig von einem in der Hohlkammer anstehenden Fluidbetriebsdruck wölbend verformt. Unter Fluidbetriebsdruck ist dabei ein im bestimmungsgemäßen Gebrauch der Brause auftretender Druck des der Brause zugeführten Fluids zu verstehen. Dieses Verformen des Strahlaustrittselements durch den im Betrieb der Brausestrahlaustrittsvorrichtung auftretenden Fluidbetriebsdruck beugt besonders vorteilhaft Funktionsausfällen bzw. Funktionseinschränkungen aufgrund von Schmutzpartikeln und Verkalkung vor. Durch die Verformung wird das Anhaften von Schmutz und Kalkpartikeln erschwert, und eventuell bereits anhaftende Verschmutzungen bzw. Kalkpartikel können leicht und einfach gelöst bzw. entfernt werden. Das kann den erforderlichen Reinigungsaufwand für die Brausestrahlaustrittsvorrichtung signifikant verringern. Das mit höherem Fluidbetriebsdruck zunehmende Verformen des Strahlaustrittselements begünstigt hierbei eine Selbstreinigungsfunktion der Brausestrahlaustrittsvorrichtung im Betrieb, indem eine beginnende Verstopfung der Feinstrahlöffnungen z.B. durch beginnende Kalkablagerungen zu einem erhöhten Fluidbetriebsdruck in der Hohlkammer des Strahlaustrittselements führt, wodurch die Verformung verstärkt wird, durch welche die beginnende Verstopfung der Brause selbsttätig wieder abgelöst bzw. zum Abplatzen gebracht werden kann.The bottom and the side wall of the jet outlet element are made of an elastic material, preferably in one piece of the same elastic material. Optionally, the entire jet outlet element can be made in one piece from the elastic material. The elastic material may in particular be an elastomeric material, such as a conventional silicone-based elastomeric material. The jet outlet element is designed such that it buckles with its bottom and / or its side wall as a function of a pending in the hollow chamber fluid operating pressure. Under fluid operating pressure is to be understood in the normal use of the shower pressure of the shower supplied fluid. This deformation of the jet outlet element by the fluid operating pressure occurring during operation of the effervescent spray outlet device advantageously prevents functional failures or functional restrictions due to dirt particles and calcification. Due to the deformation, the adhesion of dirt and lime particles is made more difficult, and possibly already adhering soiling or lime particles can be easily and simply loosened or removed. This can significantly reduce the required cleaning effort for the effervescent spray outlet device. That with Increased fluid operating pressure increasing deformation of the jet outlet element favors this a self-cleaning function of the spray jet outlet device in operation by an incipient blockage of the fine jet openings eg by incipient calcification leads to increased fluid operating pressure in the hollow chamber of the jet outlet element, whereby the deformation is enhanced by which the incipient blockage of the shower automatically again detached or can be brought to spalling.
Es zeigt sich, dass sich diese erfindungsgemäße Brausestrahlaustrittsvorrichtung mit relativ geringem Aufwand herstellen und funktionssicher betreiben lässt. Die Feinstrahlöffnungen können mit relativ geringem Durchlass- bzw. Austrittsquerschnitt in den Boden des Strahlaustrittselements eingebracht werden. Zugeführtes Brausefluid gelangt in die Hohlkammer des topfförmigen Strahlaustrittselements und kann von dort durch die Feinstrahlöffnungen hindurch als Fein-/Nadelstrahl aus der Brausestrahlaustrittsvorrichtung austreten. Die topfförmige Gestaltung des Strahlaustrittselements kann die Anfälligkeit der Brausestrahlaustrittsvorrichtung für Verstopfungen der Feinstrahlöffnungen aufgrund anlagernder Schmutz-/Kalkpartikel gering halten und das Entfernen von eventuell anhaftenden Schmutz-/Kalkpartikeln erleichtern. Dazu trägt bei, dass aufgrund dieser topfförmigen Gestaltung des Strahlaustrittselements die zu durchströmende Länge der Feinstrahlöffnungen auf die Wanddicke des Bodens begrenzt ist, die deutlich kleiner gehalten werden kann als die gesamte axiale Länge des Strahlaustrittselements, in entsprechenden Ausführungen kleiner als ein Fünftel oder auch kleiner als ein Zehntel derselben.It can be seen that this effervescent spray outlet device according to the invention can be produced and operated reliably with relatively little effort. The fine jet openings can be introduced into the bottom of the jet outlet element with a relatively small passage or exit cross section. Feed effervescent fluid enters the hollow chamber of the pot-shaped jet outlet element and can escape from there through the fine jet openings as a fine / needle jet from the effervescent spray outlet device. The cup-shaped design of the jet outlet element can keep the susceptibility of the spray jet outlet device for blockages of the fine jet openings due to accumulating dirt / lime particles low and facilitate the removal of any adhering dirt / lime particles. This contributes to the fact that due to this cup-shaped design of the jet outlet element to be flowed through the length of the fine jet openings is limited to the wall thickness of the bottom, which can be kept significantly smaller than the entire axial length of the jet outlet element, in corresponding embodiments smaller than a fifth or smaller than a tenth of the same.
Die erfindungsgemäße Brausestrahlaustrittsvorrichtung kann eine beliebige Anzahl solcher Strahlaustrittselemente entsprechend der Anzahl zugehöriger Strahlscheibenöffnungen aufweisen, vorzugsweise eine Mehrzahl von über die Ausdehnung einer zugehörigen Strahlscheibenfläche hinweg gleichmäßig verteilt angeordneten Strahlaustrittselementen.The effervescent spray outlet device according to the invention can have any number of such jet outlet elements corresponding to the number of associated jet disk openings, preferably a plurality of jet exit elements uniformly distributed over the extent of an associated jet disk surface.
Je nach Bedarf kann das eine oder können die mehreren Strahlaustrittselemente mit seinem/ihrem Boden außenbündig mit der Strahlscheibe abschließen oder gegenüber deren Außenseite etwas zurückgesetzt sein oder vorzugsweise über die Strahlscheibe nach außen vorstehen. In letzterem Fall kann es weiter bevorzugt sein, wenn das Strahlaustrittselement auch noch mit einem an den Boden anschließenden Bereich seiner Seitenwandung über die Strahlscheibe nach außen vorsteht. In entsprechenden Realisierungen steht das Strahlaustrittselement mit mehr als der halben axialen Länge seiner Seitenwandung über die Strahlscheibe nach außen vor. Dies begünstigt das vom Fluiddruck abhängige Verformen des Strahlaustrittselements und insbesondere seiner Seitenwandung ungehindert von der Strahlscheibe.Depending on requirements, the one or more jet outlet elements can terminate flush with the jet disk with its / their bottom or be slightly set back relative to the outside thereof or preferably protrude outward beyond the jet disk. In the latter case, it may be further preferred if the Jet exit element also still projects with an adjoining the bottom region of its side wall over the jet disk to the outside. In corresponding implementations, the jet outlet element protrudes outwards beyond the jet disk with more than half the axial length of its side wall. This favors the fluid pressure dependent deformation of the jet outlet element and in particular its side wall unhindered by the jet disk.
In Weiterbildung der Erfindung sind die Feinstrahlöffnungen mit einem Durchtrittsquerschnitt von jeweils höchstens 0,2mm2, insbesondere von jeweils höchstens 0,1mm2, gefertigt. Diese Dimensionierungsmaßnahme ermöglicht die Bereitstellung eines entsprechend feinen Brausestrahls.In a further development of the invention, the fine jet openings are made with a passage cross-section of in each case at most 0.2 mm 2 , in particular of in each case at most 0.1 mm 2 . This dimensioning measure makes it possible to provide a correspondingly fine spray jet.
In Weiterbildung der Erfindung beträgt ein Außendurchmesser des Bodens und der Seitenwandung des Strahlaustrittselements höchstens 10mm, insbesondere höchstens 6mm, in entsprechenden Anwendungen auch nur höchstens 5mm oder höchstens 4mm. Auch diese Dimensionierungsmaßnahme kann zur Erzielung eines sehr feinen Brausestrahls nutzbringend sein.In a further development of the invention, an outer diameter of the bottom and the side wall of the jet outlet element is at most 10 mm, in particular at most 6 mm, in corresponding applications also only at most 5 mm or at most 4 mm. Also, this dimensioning measure can be beneficial to achieve a very fine spray jet.
In Weiterbildung der Erfindung weist der Boden des Strahlaustrittselements mindestens drei und höchstens zehn Feinstrahlöffnungen auf. Auch diese Dimensionierungsmaßnahme kann herstellungstechnisch günstig und hinsichtlich der erzielbaren Brausestrahlcharakteristik vorteilhaft sein.In a development of the invention, the bottom of the jet outlet element has at least three and at most ten fine jet openings. This dimensioning measure can also be favorable in terms of manufacturing technology and advantageous in terms of the achievable shower spray characteristic.
In Weiterbildung der Erfindung ist das Strahlaustrittselement parallel zur Strahlaustrittsrichtung zwischen einer zurückgezogenen Endstellung und einer vorbewegten Endstellung translationsbeweglich in der Strahlscheibenöffnung angeordnet, wobei es sich bei in der Hohlkammer anstehendem Fluidbetriebsdruck in der vorbewegten Endstellung befindet und bei fehlendem Fluidbetriebsdruck in der Hohlkammer in der zurückgezogenen Endstellung befindet. Dies kann in vielen Fällen funktionelle Vorteile haben. In der zurückbewegten Endstellung kann das Strahlaustrittselement ganz in die Strahlscheibenöffnung eingezogen sein, z.B. mit dieser außenbündig abschließen oder gegenüber dieser zurückgezogen sein. Alternativ ist das Strahlaustrittselement in seiner zurückbewegten Endstellung nur zu einem hinteren Teil in die Strahlscheibenöffnung zurückgezogen. In der vorbewegten Endstellung kann sich das Strahlaustrittselement z.B. mindestens mit seinem Boden außerhalb der Strahlscheibenöffnung befinden, in entsprechenden Ausführungsformen zusätzlich mit einem kleineren oder alternativ mit einem größeren Teil seiner Seitenwandung. Dies begünstigt das wölbende Verformen des Strahlaustrittselements, speziell seines Bodens und/oder seiner Seitenwandung, unter der Einwirkung des Fluidbetriebsdrucks in der Hohlkammer. In entsprechenden Ausführungsformen ist das Strahlaustrittselement insgesamt in der Strahlscheibenöffnung translationsbeweglich geführt oder alternativ mit einem rückwärtigen Bereich an der Strahlscheibe oder einem der Strahlscheibe vorgelagerten Brauseteil so gehalten, dass es sich mit seinem Boden und vorzugsweise auch seiner Seitenwandung fluiddruckabhängig vorbewegen kann, z.B. elastisch. Vorzugsweise ist das Strahlaustrittselement in Richtung der zurückbewegten Endstellung elastisch rückstellend angeordnet, so dass es sich selbsttätig in die zurückbewegte Endstellung zurückbewegt, wenn der Fluiddruck nachlässt.In a further development of the invention, the jet outlet element is arranged parallel to the beam exit direction between a retracted end position and a vorbewegten end position translationally movable in the jet disk opening, which is in pending in the hollow chamber fluid operating pressure in the vorbewegten end position and is located in the retracted end position in the absence of fluid operating pressure in the hollow chamber , This can have functional advantages in many cases. In the moved back end position, the jet outlet element can be completely retracted into the jet disk opening, for example, with this flush outside or be withdrawn against this. Alternatively, the jet outlet element is retracted in its retracted end position only to a rear part in the jet disk opening. In the vorbewegten end position, the jet outlet element For example, at least with its bottom outside of the jet disk opening, in corresponding embodiments additionally with a smaller or alternatively with a larger part of its side wall. This favors the bulging deformation of the jet outlet element, especially of its bottom and / or its side wall, under the effect of the fluid operating pressure in the hollow chamber. In corresponding embodiments, the jet outlet element is guided so as to be movable in translation in the jet disk opening or, alternatively, held with a rear region on the jet disk or shower part upstream of the spray disk so that it can advance with its bottom and preferably also its side wall in a fluid pressure-dependent manner, eg elastically. Preferably, the jet outlet element is arranged elastically restoring in the direction of the retracted end position, so that it automatically moves back into the zurückbewegte end position when the fluid pressure decreases.
In vorteilhafter Ausgestaltung ist das Strahlaustrittselement derart ausgeführt, dass bezogen auf einen drucklosen Zustand der Durchmesser seiner Seitenwandung und/oder ein Durchtrittsquerschnitt seiner Feinstrahlöffnungen durch das Wölben des Bodens und/oder der Seitenwandung bei einem Fluidbetriebsdruck von 0,5bar um mindestens 3% erhöht ist/sind und/oder bei einem Fluidbetriebsdruck von 1bar um mindestens 8% erhöht ist/sind und/oder bei einem Fluidbetriebsdruck von 1,5bar um mindestens 12% erhöht ist/sind. Es zeigt sich, dass diese Systemauslegung für das Strahlaustrittselement in einem ausreichend guten Schutz vor raschem Verstopfen durch Schmutzpartikel und/oder Kalkablagerungen gerade auch beim Einsatz in sanitären Brausen resultiert, bei denen der Wasserbetriebsdruck typisch in diesem Bereich liegt.In an advantageous embodiment, the jet outlet element is designed such that based on a non-pressurized state, the diameter of its side wall and / or a passage cross section of its fine jet openings by the buckling of the bottom and / or the side wall at a fluid operating pressure of 0.5bar is increased by at least 3% / are and / or increased by at least 8% at a fluid operating pressure of 1 bar and / or increased by at least 12% at a fluid operating pressure of 1.5 bar. It turns out that this system design for the jet outlet element results in a sufficiently good protection against rapid clogging by dirt particles and / or limescale deposits, especially when used in sanitary showers, where the water operating pressure is typically in this range.
In anderweitiger Ausgestaltung dieser Maßnahme bestehen der Boden und die Seitenwandung des Strahlaustrittselements aus einem Elastomermaterial mit einer Shore-A-Härte von höchstens 75, insbesondere von höchstens 40. Es zeigt sich, dass mit dieser Systemauslegung des Strahlaustrittselements ebenfalls das wölbende Verformen des Strahlaustrittselements in Abhängigkeit vom Fluidbetriebsdruck in günstiger Weise unterstützt wird.In another embodiment of this measure, the bottom and the side wall of the jet outlet element made of an elastomeric material having a Shore A hardness of at most 75, in particular of at most 40th It is found that with this system design of the jet outlet element also the bulging deformation of the jet outlet element in dependence supported by the fluid operating pressure in a favorable manner.
In Weiterbildung der Erfindung weist das Strahlaustrittselement eine radial von der Seitenwandung abkragende Halteschulter auf. Dies kann dazu genutzt werden, das Strahlaustrittselement an der Strahlscheibe oder einem benachbarten Bauelement sicher zu halten.In a further development of the invention, the jet outlet element on a radially projecting from the side wall retaining shoulder. This can be used to the jet outlet element to keep safe at the jet disk or an adjacent device.
In Weiterbildung der Erfindung weist das Strahlaustrittselement an seinem eintrittsseitigen Stirnende axial abstehende Abstandshalter auf. Dies kann dazu genutzt werden, das Strahlaustrittselement zwischen der Strahlscheibe und einer mit Abstand zur Innenseite der Strahlscheibe angeordneten, z.B. platten- oder scheibenförmigen Gehäuse- oder Zwischenwand der Brause zu halten, gegen die das Strahlaustrittselement mit seinem axial abstehenden Abstandshalter zur Anlage kommt. Dabei kann zwischen der Strahlscheibe und der Gehäuse- oder Zwischenwand eine Fluidaustrittskammer gebildet sein, der das Brausefluid zugeführt wird und aus der das Brausefluid in die Hohlkammer des Strahlaustrittselements gelangen kann.In a further development of the invention, the jet outlet element has axially projecting spacers on its entry-side front end. This can be used to position the jet exit element between the jet disk and a distance from the inside of the jet disk, e.g. To hold plate-shaped or disc-shaped housing or partition wall of the shower, against which the jet outlet element comes with its axially projecting spacer to the plant. It can be formed between the jet disk and the housing or intermediate wall, a fluid outlet chamber, which is supplied with the effervescent fluid and from which the effervescent fluid can get into the hollow chamber of the jet outlet element.
In Weiterbildung der Erfindung weist die Strahlscheibe mehrere Strahlscheibenöffnungen auf, in denen eine entsprechende Anzahl von Strahlaustrittselementen angeordnet ist, wobei die Strahlaustrittselemente einteilig an einer innenseitig an der Strahlscheibe anliegenden Strahlaustrittsplatte aus elastischem Material angeformt sind. Auch in diesem Fall kann es sich wiederum insbesondere um ein an sich herkömmliches Elastomermaterial handeln. Das einteilige Anformen der Strahlaustrittselemente an der Strahlaustrittsplatte kann die Fertigung der Strahlaustrittselemente und ihre Platzierung in den Strahlscheibenöffnungen vereinfachen.In a development of the invention, the jet disk has a plurality of jet disk openings, in which a corresponding number of jet outlet elements are arranged, wherein the jet outlet elements are integrally formed integrally on an inner side of the jet disk jet exit plate made of elastic material. Again, in this case, it may in particular be a conventional elastomer material. The one-part molding of the jet outlet elements on the jet outlet plate can simplify the manufacture of the jet outlet elements and their placement in the jet disk openings.
Die erfindungsgemäße Brause ist mit einer erfindungsgemäßen Brausestrahlaustrittsvorrichtung ausgerüstet. Bei der Brause kann es sich insbesondere um eine Sanitärbrause handeln, z.B. eine Duschbrause in einer Ausführung als Kopfbrause, Handbrause oder Seitenbrause.The shower according to the invention is equipped with a effervescent spray outlet device according to the invention. The showerhead may in particular be a sanitary shower, e.g. a shower head in a version as overhead shower, hand shower or side shower.

Wie sich für den Fachmann versteht, bestimmt sich die Systemauslegung für das Wölbungsverhalten des Strahlaustrittselements 6 vor allem durch entsprechende Wahl der Wanddicke für den Boden 6a und die Seitenwandung 6b sowie des Verhältnisses von axialer Länge zu Durchmesser und der Elastizität des verwendeten Materials, wie der Shore-Härte eines verwendeten Elastomermaterials. Weiter kann von Bedeutung sein, ob und mit welchem Anteil ihrer axialen Länge die Strahlaustrittselemente 6 über die Strahlscheibe 4 hinaus vorstehen. Je nach Bedarf kann das jeweilige Strahlaustrittselement so ausgelegt sein, dass sich bei anstehendem Fluiddruck nur sein Boden oder nur seine Seitenwandung wölbt oder, wie oben erläutert, sein Boden und seine Seitenwandung wölben.As will be understood by those skilled in the art, the system design for the buckling behavior of the
Durch das oben erläuterte, vom anstehenden Fluiddruck abhängige Wölben, das auch als Atmen bezeichnet werden kann, des Strahlaustrittselements 6 bleibt seine Oberfläche durch den Betrieb der Brause in Bewegung, da sich im Betrieb der Fluiddruck ändert, insbesondere zwischen dem drucklosen Zustand bei abgestellter Brause und dem jeweils gegebenen normalen Betriebsdruck des Fluids im aktiven Brausebetrieb. Dieses ständige bzw. wiederkehrende Bewegen der Oberfläche des Strahlaustrittselements 6 erschwert oder verhindert bleibende Ablagerungen von Schmutz- und Kalkpartikeln. Dies gilt insbesondere auch für den Bereich der Feinstrahlöffnungen 7, die somit über vergleichsweise lange Betriebsdauern hinweg frei von anhaftenden Schmutz-/Kalkpartikeln gehalten werden und durchgängig bleiben. Zudem können durch dieses Atmen des Strahlaustrittselements 6 evtl. angelagerte Schmutz-/Kalkablagerungen durch den Betrieb der Brause meistens selbsttätig abgelöst bzw. abgesprengt werden.By the above-explained, dependent on the upcoming fluid pressure buckling, which can also be referred to as breathing, the
Wie oben erläutert, verändern sich beim Ausführungsbeispiel der

Für das Ausführungsbeispiel der
Je nach Bedarf kann somit bei einem typischen Fluidbetriebsdruck im Bereich von 0,5bar bis 1,5bar durch Verwendung der Ausführungsvariante der
In den gezeigten Beispielen ist das jeweilige Strahlaustrittselement axial unbeweglich und seitlich geführt in der zugehörigen Strahlscheibenöffnung angeordnet. In alternativen, nicht gezeigten Ausführungsformen ist das jeweilige Strahlaustrittselement axial, d.h. in Strahlaustrittsrichtung, beweglich in der zugehörigen Strahlscheibenöffnung angeordnet, so dass es sich durch anstehenden Fluiddruck vorbewegt und dadurch aus der Strahlscheibenöffnung heraus bzw. weiter aus der Strahlscheibenöffnung heraus bewegt. Dies begünstigt je nach Ausführungsvariante das Wölben seines Bodens und/oder seiner Seitenwand durch den Fluiddruck. Dem Fachmann sind verschiedene Realisierungsmöglichkeiten für eine derartige axialbewegliche Halterung eines Strahlaustrittselementes in einer Strahlscheibenöffnung an sich bekannt, was daher hier keiner näheren Erläuterungen bedarf. In weiteren alternativen, nicht gezeigten Ausführungsformen ist das jeweilige Strahlaustrittselement mit seitlichem Abstand zur zugehörigen Strahlscheibenöffnung angeordnet, so dass sich seine Seitenwandung durch den Fluiddruck bei Bedarf nicht nur in einem aus der Strahlscheibenöffnung axial vorstehenden Bereich, sondern auch in einem nicht aus der Strahlscheibenöffnung axial vorstehenden Bereich wölben kann.In the examples shown, the respective jet outlet element is axially immovable and guided laterally in the associated jet disk opening. In alternative embodiments, not shown, the respective jet exit element is axial, i. in the beam exit direction, movably arranged in the associated jet disk opening, so that it advances by pending fluid pressure and thereby moves out of the jet disk opening out or further out of the jet disk opening. This favors depending on the embodiment, the buckling of its bottom and / or its side wall by the fluid pressure. The person skilled in various realization possibilities for such axially movable mounting a jet outlet element in a jet disk opening are known per se, which therefore requires no further explanation here. In further alternative, not shown embodiments, the respective jet outlet element is arranged at a lateral distance to the associated jet disk opening, so that its side wall by the fluid pressure if necessary not only in an axially projecting from the jet disk opening area, but also in a not axially projecting from the jet disk opening Area can bulge.
Wie die gezeigten und oben erwähnten Ausführungsbeispiele deutlich machen, stellt die Erfindung eine Brausestrahlaustrittsvorrichtung bereit, die vergleichsweise unempfindlich gegen Verstopfungserscheinungen durch Schmutzpartikel und Kalkablagerungen ist und bei Bedarf dergestalt realisierbar ist, dass sie einen besonders feinen, auf Wunsch quasi nebelartig feinen Brausestrahl erzeugen kann. Dazu können die Feinstrahlöffnungen mit einem sehr geringen Durchtrittsquerschnitt vorzugsweise in ein elastisches Bodenmaterial des jeweiligen Strahlaustrittselements eingebracht werden. Das fluiddruckabhängige Atmen des Strahlaustrittselements beugt Verstopfungen der kleinen Feinstrahlöffnungen vor. Indem sich der Querschnitt der Feinstrahlöffnungen 7 in seiner Fläche und in seiner Form, z.B. wie in den gezeigten Ausführungen zwischen oval und kreisrund, signifikant verändert, können evtl. angelagerte Schmutz-/Kalkpartikel selbststätig zum Ablösen bzw. Abplatzen gebracht werden, und dem Entstehen von die Feinstrahlöffnungen 7 in ihrem freien Durchflussquerschnitt merklich verengenden Schmutz-/Kalkablagerungen wird effektiv entgegengewirkt.As the illustrated and above-mentioned embodiments make it clear, the invention provides a effervescent spray outlet device which is comparatively insensitive to clogging phenomena by dirt particles and limescale deposits and if necessary can be realized in such a way that they can produce a particularly fine, virtually fog-like fine shower spray. For this purpose, the fine jet openings with a very small passage cross-section can preferably be introduced into an elastic bottom material of the respective jet outlet element. The fluid pressure-dependent breathing of the jet outlet element prevents blockages of the small fine jet openings. By the cross section of the
Es versteht sich, dass die Erfindung neben den gezeigten und den oben erläuterten Ausführungsvarianten weitere Realisierungen der Brausestrahlaustrittsvorrichtung umfasst, wobei lediglich zwingend ist, dass das in der zugehörigen Strahlscheibenöffnung angeordnete Strahlaustrittselement topfförmig gestaltet und mit seinem Boden in Strahlaustrittsrichtung weisend angeordnet ist und im Boden eine Mehrzahl von Feinstrahlöffnungen vorgesehen ist. Die Brausestrahlaustrittsvorrichtung kann für jedwede herkömmliche Art von Sanitärbrausen, wie Duschbrausen, Küchenbrausen und Brausen für Mischerarmaturen, und nicht-sanitären Brausen Verwendung finden.It goes without saying that the invention comprises, in addition to the variants of embodiment shown and explained above, further implementations of the effervescent spray outlet device, wherein it is only mandatory that the jet outlet element arranged in the associated jet disk opening is cup-shaped and arranged with its bottom facing in the jet exit direction and a plurality in the bottom is provided by fine jet openings. The effervescent spray exit device may find use in any conventional type of sanitary showerheads, such as showerheads, kitchen showers and mixers for mixer taps, and non-sanitary showers.
