Definitions
- the invention relates to a washbasin device according to the preamble of patent claim 1.
- This washbasin device belongs to a type of washbasin devices which includes a washbasin with a washbasin recess and a water delivery device which is designed to deliver water in the form of a fountain jet consisting of individual jets and has a plurality of water delivery nozzles which are in the washbasin recess to deliver the individual jets associated individual jet directions are arranged diagonally upwards from the sink recess and back into the sink recess.
- the washbasin device can, for example, serve as a washing place in a bathroom or the like, where the user can wash themselves or carry out various other personal care measures. While washbasin devices usually have a sanitary outlet fitting with an outlet pipe ending above the sink recess as the sole water delivery device, in the present washbasin device the water delivery device is designed to deliver the special fountain jet.
- a washbasin device of this type is in the patent specifications US 7,155,759 B2 and US 7,461,419 B2 disclosed.
- the water delivery nozzles are formed by water delivery openings in the washbasin trough, which are arranged in a preferably irregular pattern over the entire trough or at least in an upper region of the trough over the entire circumference of the trough.
- the water delivery nozzles are all aligned with their associated individual jet directions towards a central area above the sink recess, so that a dome-like fountain jet results.
- the pattern of the water delivery openings above can come through in a lower part of the trough Drain openings of the same shape can be continued, which act as a water drain.
- the sink recess has a standard, central water drain.
- the water delivery nozzles are arranged within a strip-shaped nozzle occupancy area with a strip length extending in the circumferential direction of the trough and a strip height perpendicular thereto.
- the strip length of the nozzle occupancy area is greater than its strip height, and the nozzle occupancy area extends with its strip length over at most half the circumference of the trough.
- the patent specification US 2007/061960 A1 discloses a generic washbasin device, in which two nozzle occupancy areas, each with a group of water delivery openings, are arranged symmetrically on two opposite sides on the inner wall surface of the washbasin recess. Specifically, there are three water dispensing ports in each group, with an adjustable water dispensing nozzle installed in each water dispensing port.
- the jet exit direction of each individual water delivery nozzle consisting of a ball socket and a rotatable ball valve, can be adjusted by the user for each water delivery nozzle.
- the disclosure document WO 2012/033350 A2 reveals a multifunctional sink with a hinged lid, which when closed is used for cleaning Dishes, fruits, vegetables and the like are designed by spraying water from the water delivery nozzles.
- the water delivery nozzles have a cone-shaped water jet characteristic and are arranged, among other things, in spray pipes at intervals with different orientations, with the respective spray pipe being rotatably mounted on both sides.
- Such a spray pipe is located in a recess on all four inner wall surfaces of the sink recess.
- the technical problem of the invention is the provision of a washbasin device of the type mentioned at the beginning, the water delivery device of which enables the delivery of water in the form of a fountain jet that is alternative to the prior art explained above, the jet pattern of which offers significant application advantages.
- the invention solves this problem by providing a washbasin device with the features of claim 1.
- the water delivery nozzles are arranged within a strip-shaped nozzle occupancy area with a strip length extending in the circumferential direction of the trough and a strip height perpendicular thereto.
- the strip length of the nozzle occupancy area is greater than its strip height, and the nozzle occupancy area extends with its strip length over at most half the circumference of the trough.
- the water delivery nozzles are arranged in at least two nozzle groups, each with a plurality of water delivery nozzles, which follow one another in the circumferential direction of the trough.
- a maximum difference in jet exit directions of the water delivery nozzles of a respective nozzle group is less than a minimum difference in the jet exit directions of the water delivery nozzles of two adjacent nozzle groups.
- the individual jets of the nozzles within each nozzle group run in the same or comparatively slightly different directions, while the individual jet directions of the water delivery nozzles of two adjacent nozzle groups are more different from one another. It turns out that this measure has a special effect
- An advantageous jet pattern can be achieved for the fountain jet, which is optimal for many applications.
- the washbasin device enables the delivery of water in the form of a fountain jet, which is advantageous for many applications.
- This special nozzle occupancy area makes it possible to provide the fountain jet in its shape and in particular its jet pattern, similar to, for example, a surge jet with a jet cross-section perpendicular to the direction of jet propagation, which has a larger, preferably several times larger, horizontal jet width than a vertical jet width, i.e. jet height owns.
- the fountain jet can provide a more localized water flow over its jet path compared to the conventional, dome-shaped fountain jet mentioned, which leaves larger areas free above the sink recess, so that the user does not get himself wet unnecessarily or undesirably as long as he acts in these areas, and In the water-covered area there is a relatively dense flow of water over the course of the fountain jet, which the user can use effectively for his application.
- This fountain jet differs from a usual surge jet and from other usual water delivery jets using outlet fittings with an outlet pipe ending above the trough in that it runs obliquely upwards and then obliquely downwards like a parabola and its composition consists of the plurality of individual jets emitted through the water delivery nozzles.
- the fountain jet is suitable, among other things, for washing hands, washing your face, brushing your teeth, filling cups or the like with water, rinsing containers, rinsing objects, etc. Thanks to its combined parabola and fan shape, it is also particularly suitable for washing hair or for head trimming and beard cleaning. Due to the lack of a water outlet pipe above the sink recess, the user has unhindered space for his head above the recess for these applications.
- any conventional implementations can be used for the water delivery nozzles.
- the nozzles can be used as pure outlet openings in the sink recess or as Independent nozzle elements can be realized, for example in the form of corresponding jet outlet nipples, which are placed in corresponding nozzle receiving openings in the trough.
- Particularly advantageous are special fine/mist jet nozzles, such as those used in shower facilities sold by the applicant under the PowderRain brand and as also described in the published patent application DE 10 2016 225 987 A1 are disclosed by the applicant, or other conventional fine jet nozzles or needle jet nozzles, alternatively also conventional normal jet nozzles, such as those commonly installed in shower heads, can be used.
- the nozzle occupancy area extends with its strip length over a maximum of a quarter of the circumference of the trough. This further contributes to a desired good localization of the water released by the water delivery device within the correspondingly localized fountain jet consisting of the bundle of individual jets.
- the nozzle occupancy area extends with its strip length over at least a fifth and at most a quarter of the circumference of the trough.
- the water delivery nozzles are arranged in at least two rows of nozzles in the nozzle occupancy area, the water delivery nozzles of a respective row of nozzles being arranged offset in the circumferential direction of the trough in relation to the water delivery nozzles of an adjacent row of nozzles. It turns out that this specific arrangement of the water delivery nozzles further contributes to a fountain jet pattern that is optimal for most washing applications.
- the nozzle occupancy area is located in a rear half of the washbasin recess facing away from the user side.
- the term "back half facing away from the user side” means that half of the washbasin recess which is opposite the front half of the washbasin recess, with the front denoting the side of the washbasin recess on which the user approaches the washbasin recess or stands in front of it when using the washbasin device as intended.
- a mirror or mirror cabinet is often arranged on the opposite back of the sink recess or washbasin.
- the water delivery device directs the fountain jet towards the user, be it from back to front directly towards him or alternatively in a direction obliquely from behind or sideways back to front or sideways forward.
- This positioning of the nozzle occupancy area generally proves to be particularly favorable for the vast majority of typical washing applications.
- the washbasin recess has a water drain in the front half facing the user side, with a fountain jet impact area, i.e. the area in which the fountain jet hits the washbasin recess, lying on a side of the water drain facing the nozzle occupancy area.
- a fountain jet impact area i.e. the area in which the fountain jet hits the washbasin recess, lying on a side of the water drain facing the nozzle occupancy area.
- the water outlet is slot-shaped with a longitudinal slot axis perpendicular to a lateral fountain jet main direction component.
- This slot shape of the water drain is advantageously coordinated with the shape of the fountain jet and further contributes to an optimized removal of the water that reaches the sink recess through the fountain jet.
- the water delivery nozzles are specifically arranged in three nozzle groups which follow one another in the circumferential direction of the trough, the water delivery nozzles of a respective nozzle group having the same lateral jet exit direction components and the lateral jet exit direction components of two lateral nozzle groups being inclined towards the lateral jet exit direction component of a central nozzle group by an equal oblique angle amount.
- lateral jet exit direction component means that directional component of the jet exit directions of the individual jets determined by the nozzles, which results for the lateral, i.e. horizontal, projection of the jet exit direction perpendicular to the vertical height direction.
- the washbasin device includes a water distributor body on an underside of the washbasin recess in the nozzle occupancy area.
- the water distributor body extends over the length of the Nozzle occupancy area extending water supply chamber and a water distribution chamber separated from the water supply chamber by a partition and in fluid communication with the water supply chamber via a plurality of passage openings in the partition.
- the water delivery nozzles are coupled to the water distribution body, the water delivery nozzles being in fluid communication with the water distribution chamber via side inlet openings.
- the water By separating into the water supply chamber and the water distribution chamber in fluid communication with it via the passage openings, the water can be supplied to the various water dispensing nozzles comparatively evenly and consequently with the same pressure conditions .
- the water delivery nozzles are in turn easily able to emit similar individual jets, ie individual jets with essentially the same throw height and throw distance of their throw parabola shape.
- the washstand device illustrated in the figures comprises a washstand 1 with a washbasin trough 2 and a water delivery device 3, which is designed to deliver water in the form of a fountain jet consisting of individual jets and has a plurality of water delivery nozzles 4.
- the water delivery nozzles 4 are arranged in the washbasin trough 2 to deliver the individual jets in the associated individual jet directions from the washbasin trough 2 diagonally upwards and back into the washbasin trough 2.
- the Fig. 6 to 10 show the wash basin device with activated water delivery device 3, which then delivers supplied water as a fountain jet 5, which is composed of individual jets 11 which are emitted by the water delivery nozzles 4.
- the water delivery nozzles 4 are arranged within a strip-shaped nozzle occupancy area 6 with a strip length D L extending in the circumferential direction of the trough and a strip height D H perpendicular thereto, its strip length D L being greater than its strip height and its strip length extending over at most half the circumference of the trough.
- the strip length D L which runs in a horizontal plane in a normal position of use of the washbasin device, namely in accordance with the shape of the trough 2, for example with a curved course, and the strip height D H perpendicular thereto are exemplary in the Fig. 1 and 2 registered.
- the nozzle occupancy area 6, as in the example shown extends with its strip length D L over a maximum of a quarter of the circumference of the trough, for example over a length that lies between a fifth and a quarter of the circumference of the trough.
- the strip height D H is several times smaller than the strip length D L , for example smaller by at least a factor of 5 or at least a factor of 10 or at least a factor of 15 or at least a factor of 20 or at least a factor of 25.
- the sink trough 2 is circular, as in the example shown. In alternative embodiments it has a different shape, for example oval or square or any other shape, for example irregular.
- the water delivery nozzles 4 are arranged in the nozzle occupancy area 6 in at least two rows of nozzles 7 1 , 7 2 , with the water delivery nozzles 4 of a respective row of nozzles 7 1 , 7 2 offset in the circumferential direction of the trough in relation to the water delivery nozzles 4 of an adjacent row of nozzles 7 1 , 7 2 are arranged.
- the water delivery nozzles 4 of adjacent rows of nozzles 7 1 , 7 2 are arranged centrally offset, ie each nozzle 4 of one row of nozzles lies centrally between two mutually adjacent nozzles 4 of the other row of nozzles, viewed in the circumferential direction of the trough.
- the nozzles 4 in the adjacent nozzle rows 7 1 , 7 2 are arranged offset relative to one another by half the nozzle distance of the nozzles 4 within the respective nozzle row 7 1 , 7 2 .
- an off-center offset is selected.
- the nozzle occupancy area 6 contains exactly two rows of nozzles 7 1 , 7 2 , in alternative embodiments it contains more than two rows of nozzles, for example between three and eight rows of nozzles.
- the nozzle occupancy area 6 is located in a back half 2a of the washbasin trough 2 facing away from the user side.
- This back half 2a is located towards the user side Front half 2b of the sink recess 2 opposite.
- the front half 2b of the trough 2 facing the user side faces a front side 8 of the trough 2 and the washbasin 1 as a whole, which forms the user side when the washbasin device is used as intended, ie the side to which the user approaches when he wants to use the washbasin device.
- This front 8 is opposite a back 9 of the trough 2 and the washbasin 1, on which, in typical washbasin devices, there is, for example, a mirror or mirror cabinet, which is of no further interest here and is therefore not shown.
- the nozzle occupancy area 6 is at least partially located in the front half 2b of the washbasin recess 2 facing the user side, that is, with a corresponding part closer to the front 8 than to the back 9 of the recess 2 or the washbasin 1.
- the sink trough 2 has a water drain 10 in the front half 2b facing the user, as in the example shown.
- a fountain jet impact area F A of the sink trough 2 lies on a side of the water drain 10 facing the nozzle occupancy area 6.
- the fountain jet impact area here refers to the area F A of the trough 2 within which the fountain jet 5 hits the trough surface when it is not used by the user and is therefore interrupted by him.
- the fountain impact area F A is preferably in the immediate vicinity or in any case only a short distance of at most a few centimeters to or from the water drain 10.
- the water drain 10 offset from the center of the trough towards the front 8 are optimized in connection with the rearward positioning of the water dispensing device 3 shape and use of the fountain jet 5 and the water drainage from the trough 2.
- the water drain is, as usual, in a central area of the sink trough 2 or offset to the rear relative to it, and / or the fountain jet Impact area F A lies on the side of the water outlet 10 facing away from the nozzle occupancy area 3.
- the water outlet 10, as in the exemplary embodiment shown, is formed in the form of a slot with a slot longitudinal axis Ls perpendicular to a lateral fountain jet main direction component F H.
- the main direction component of the fountain jet is the directional component F H along which the fountain jet 5 mainly spreads in horizontal projection. In the example shown, this is the direction from back to front, ie the direction from the back 9 to the front 8 of the trough 2 or the washbasin 1, as in the 9 and 10 entered as an example.
- the water outlet 10 is formed in the form of a slot with a slot longitudinal axis Ls which is oblique to the lateral fountain jet main direction component FH , or the water outlet 10 is of another conventional shape, for example circular or oval.
- jet exit directions S ij of the individual jets of the water delivery nozzles 4 generally correspond to the longitudinal axis of the respective water delivery nozzle 4 and have a vertical component upwards and a horizontal component running transversely to the front and/or perpendicular thereto.
- the beam exit direction S ij is given for some individual beams 11 1 to 11e represented there.
- the choice of the jet exit directions S ij for the individual jets determines the parabolic shape of the fountain jet 5, in particular with regard to the throwing height and the throwing distance, ie with regard to the maximum height of the fountain jet above the wash basin trough 2 and the position of it Impact area F A on the trough 2.
- the water delivery device 3 is set up to generate the fountain jet 5 with a throw height that is between 80% and 120% of the throw distance, ie the maximum height of the fountain jet at its apex or upper reversal point is between 80% and 120% of the distance of the impact area F A from the nozzle occupancy area 6. In typical cases this means a fountain jet height between approximately 20cm and approximately 40cm above the trough 2.
- the water delivery nozzles 4 are, as shown, arranged in at least two nozzle groups 4 1 , 4 2 which follow one another in the circumferential direction of the trough, each with several of the water delivery nozzles 4.
- a maximum difference in jet exit directions of the water delivery nozzles 4 of a respective nozzle group for example the nozzle group 4 1 or the nozzle group 4 2 , is less than a minimum difference in the jet exit directions of the water delivery nozzles 4 of two adjacent nozzle groups, such as the nozzle groups 4 1 and 4 2 .
- the water delivery nozzles 4 are arranged, as in the example shown, in three nozzle groups 4 1 , 4 2 , 4 3 which follow one another in the circumferential direction of the trough, the water delivery nozzles 4 of a respective nozzle group having the same lateral jet exit direction components S Hj and the lateral jet exit direction components of two lateral nozzle groups 4 1 , 4 3 is inclined towards the lateral jet exit direction component of a central nozzle group 4 2 by an equal oblique angle amount W D.
- the lateral jet exit direction component here means the horizontal projection component of the jet exit direction of the respective water delivery nozzle 4 and thus of the individual jet 11 emitted by it.
- FIG. 3 to 5 This nozzle grouping and the mentioned relationships with regard to the jet exit directions of the water delivery nozzles 4 are illustrated using an example case and using representative individual jets.
- the water delivery nozzles 4 of the middle nozzle group 4 2 emit their individual jets obliquely upwards and in a horizontal projection, all with the same lateral jet exit direction component S H2 , which in this exemplary example case exactly from back to front, ie in the direction from the back 9 to the front 8 without lateral component, runs.
- Two associated individual jets 11 1 , 11 2 are connected to the two end-side water delivery nozzles 4 of the middle nozzle group 4 2 in the Fig. 3 to 5 reproduced, in Fig. 5 additionally the associated lateral beam exit direction component S H2 .
- the individual jets of the remaining water delivery nozzles 4 of the middle nozzle group 4 2 lie accordingly between these two edge individual jets 11 1 , 11 2 of the middle nozzle group 4 2 .
- the said oblique angle amount W D is also specified, by which the lateral jet exit direction component S H1 , S H3 of the respective side nozzle group 4 1 , 4 3 is inclined towards the lateral jet exit direction component S H2 of the middle nozzle group 4 2 .
- the maximum difference in the jet exit directions Sij of the water delivery nozzles 4 of a respective nozzle group 4 1 , 4 2 , 4s is equal to zero. Because this difference is equal to zero for both the first nozzle group 4 1 as well as the second nozzle group 4 2 and the third nozzle group 4 3 , so that the maximum difference when considering all nozzle groups 4 1 to 4 3 is also equal to zero.
- the jet exit directions S ij of the water delivery nozzles 4 of the two adjacent nozzle groups 4 1 and 4 2 differ in horizontal projection by the oblique angle amount W D
- the jet exit directions S ij of the water delivery nozzles 4 of the two adjacent nozzle groups 4 2 and 4 3 also differ by the in the selected exemplary example, the same slant angle amount W D , so that the minimum difference in horizontal projection is equal to the slant angle amount W D and therefore greater than zero and is therefore greater than the maximum difference between the jet exit directions S ij of the water delivery nozzles 4 of each nozzle group 4 1 to 4s.
- this arrangement of the water delivery nozzles 4 results in a stripe-like or fan-like course/jet pattern of the fountain jet 5 with a central fountain-shaped jet stripe bent like a parabola, which is emitted by the middle nozzle group 42 , and two side jet strips that are inclined towards each other and convergent towards each other middle jet strips have practically the same throwing height and throwing distance of their parabolic arc shape and thereby connect with the central strip to form the fountain jet 5 as a homogeneous overall jet.
- the water delivery nozzles 4 are arranged in at least one of the three nozzle groups 4 1 , 4 2 , 4 3 with two or more different jet exit directions instead of all with the same jet exit direction, for example the water delivery nozzles of at least one of the nozzle groups 4 1 , 4 2 , 4a such that that the jet strip emitted by this nozzle group 4 1 and/or 4 2 and/or 4 3 results in a slightly convergent or slightly divergent jet instead of a jet with a constant width.

Diese Waschtischeinrichtung gehört zu einem Typ von Waschtischeinrichtungen, der einen Waschtisch mit einer Waschbeckenmulde und eine Wasserabgabevorrichtung umfasst, die zur Abgabe von Wasser in Form eines aus Einzelstrahlen bestehenden Fontänenstrahls ausgelegt ist und eine Mehrzahl von Wasserabgabedüsen aufweist, die in der Waschbeckenmulde zur Abgabe der Einzelstrahlen in zugehörigen Einzelstrahlrichtungen von der Waschbeckenmulde aus schräg nach oben und wieder in die Waschbeckenmulde zurück angeordnet sind.This washbasin device belongs to a type of washbasin devices which includes a washbasin with a washbasin recess and a water delivery device which is designed to deliver water in the form of a fountain jet consisting of individual jets and has a plurality of water delivery nozzles which are in the washbasin recess to deliver the individual jets associated individual jet directions are arranged diagonally upwards from the sink recess and back into the sink recess.
Die Waschtischeinrichtung kann beispielsweise als Waschplatz in einem Badezimmer oder dgl. dienen, an dem sich der Benutzer waschen bzw. diverse andere Körperpflegemaßnahmen vornehmen kann. Während Waschtischeinrichtungen meist eine sanitäre Auslaufarmatur mit einem über der Waschbeckenmulde endenden Auslaufrohr als alleinige Wasserabgabeeinrichtung aufweisen, ist bei der vorliegenden Waschtischeinrichtung die Wasserabgabeeinrichtung zur Abgabe des speziellen Fontänenstrahls ausgelegt.The washbasin device can, for example, serve as a washing place in a bathroom or the like, where the user can wash themselves or carry out various other personal care measures. While washbasin devices usually have a sanitary outlet fitting with an outlet pipe ending above the sink recess as the sole water delivery device, in the present washbasin device the water delivery device is designed to deliver the special fountain jet.

Die Offenlegungsschrift
Der Erfindung liegt als technisches Problem die Bereitstellung einer Waschtischeinrichtung der eingangs genannten Art zugrunde, deren Wasserabgabevorrichtung die Abgabe von Wasser in Form eines gegenüber dem oben erläuterten Stand der Technik alternativen Fontänenstrahls ermöglicht, dessen Strahlbild signifikante Anwendungsvorteile bietet.The technical problem of the invention is the provision of a washbasin device of the type mentioned at the beginning, the water delivery device of which enables the delivery of water in the form of a fountain jet that is alternative to the prior art explained above, the jet pattern of which offers significant application advantages.
Die Erfindung löst dieses Problem durch die Bereitstellung einer Waschtischeinrichtung mit den Merkmalen des Anspruchs 1.The invention solves this problem by providing a washbasin device with the features of
Bei der erfindungsgemäßen Waschtischeinrichtung sind, wie bereits oben erwähnt, die Wasserabgabedüsen innerhalb eines streifenförmigen Düsenbelegungsbereichs mit sich in Muldenumfangsrichtung erstreckender Streifenlänge und dazu senkrechter Streifenhöhe angeordnet. Dabei ist die Streifenlänge des Düsenbelegungsbereichs größer als seine Streifenhöhe, und der Düsenbelegungsbereich erstreckt sich mit seiner Streifenlänge über höchstens den halben Muldenumfang.In the washbasin device according to the invention, as already mentioned above, the water delivery nozzles are arranged within a strip-shaped nozzle occupancy area with a strip length extending in the circumferential direction of the trough and a strip height perpendicular thereto. The strip length of the nozzle occupancy area is greater than its strip height, and the nozzle occupancy area extends with its strip length over at most half the circumference of the trough.
Weiter sind bei der erfindungsgemäßen Waschtischeinrichtung die Wasserabgabedüsen in wenigstens zwei in Muldenumfangsrichtung aufeinanderfolgenden Düsengruppen mit jeweils mehreren Wasserabgabedüsen angeordnet. Dabei ist eine maximale Differenz von Strahlaustrittsrichtungen der Wasserabgabedüsen einer jeweiligen Düsengruppe geringer als eine minimale Differenz der Strahlaustrittsrichtungen der Wasserabgabedüsen zweier benachbarter Düsengruppen. Mit anderen Worten verlaufen die Einzelstrahlen der Düsen innerhalb einer jeden Düsengruppe in gleichen oder vergleichsweise wenig voneinander verschiedenen Richtungen, während die Einzelstrahlrichtungen der Wasserabgabedüsen je zweier benachbarter Düsengruppen stärker voneinander verschieden sind. Es zeigt sich, dass sich mit dieser Maßnahme ein besonders vorteilhaftes Strahlbild für den Fontänenstrahl erzielen lässt, wie es für viele Anwendungen optimal ist.Furthermore, in the washbasin device according to the invention, the water delivery nozzles are arranged in at least two nozzle groups, each with a plurality of water delivery nozzles, which follow one another in the circumferential direction of the trough. A maximum difference in jet exit directions of the water delivery nozzles of a respective nozzle group is less than a minimum difference in the jet exit directions of the water delivery nozzles of two adjacent nozzle groups. In other words, the individual jets of the nozzles within each nozzle group run in the same or comparatively slightly different directions, while the individual jet directions of the water delivery nozzles of two adjacent nozzle groups are more different from one another. It turns out that this measure has a special effect An advantageous jet pattern can be achieved for the fountain jet, which is optimal for many applications.
Mit dieser speziellen Wasserabgabevorrichtung ermöglicht die erfindungsgemäße Waschtischeinrichtung die Abgabe von Wasser in Form eines für viele Anwendungen vorteilhaften Fontänenstrahls. Durch diesen speziellen Düsenbelegungsbereich ist es möglich, den Fontänenstrahl in seiner Form und insbesondere seinem Strahlbild ähnlich wie z.B. ein Schwallstrahl mit einem zur Strahlausbreitungsrichtung senkrechten Strahlquerschnitt bereitzustellen, der eine gegenüber einer vertikalen Strahlbreite, d.h. Strahlhöhe, größere, vorzugsweise um ein Mehrfaches größere, horizontale Strahlbreite besitzt. Der Fontänenstrahl kann einen im Vergleich zu dem erwähnten herkömmlichen, kuppelförmigen Fontänenstrahl über seinen Strahlverlauf hinweg stärker lokalisierten Wasserfluss bereitstellen, der größere Bereiche über der Waschbeckenmulde freilässt, so dass der Anwender sich nicht unnötig oder unerwünscht nass macht, solange er in diesen Bereichen agiert, und im wasserbelegten Bereich einen über den Verlauf des Fontänenstrahls hinweg relativ dichten Wasserfluss besitzt, den der Anwender effektiv für seine Anwendung nutzen kann. Von einem üblichen Schwallstrahl und von anderen üblichen Wasserabgabestrahlen unter Verwendung von Auslaufarmaturen mit einem über der Mulde endenden Auslaufrohr unterscheidet sich dieser Fontänenstrahl durch seinen wurfparabelartig schräg nach oben und dann schräg nach unten gerichteten Verlauf und seine Zusammensetzung aus der Mehrzahl von durch die Wasserabgabedüsen abgegebenen Einzelstrahlen.With this special water delivery device, the washbasin device according to the invention enables the delivery of water in the form of a fountain jet, which is advantageous for many applications. This special nozzle occupancy area makes it possible to provide the fountain jet in its shape and in particular its jet pattern, similar to, for example, a surge jet with a jet cross-section perpendicular to the direction of jet propagation, which has a larger, preferably several times larger, horizontal jet width than a vertical jet width, i.e. jet height owns. The fountain jet can provide a more localized water flow over its jet path compared to the conventional, dome-shaped fountain jet mentioned, which leaves larger areas free above the sink recess, so that the user does not get himself wet unnecessarily or undesirably as long as he acts in these areas, and In the water-covered area there is a relatively dense flow of water over the course of the fountain jet, which the user can use effectively for his application. This fountain jet differs from a usual surge jet and from other usual water delivery jets using outlet fittings with an outlet pipe ending above the trough in that it runs obliquely upwards and then obliquely downwards like a parabola and its composition consists of the plurality of individual jets emitted through the water delivery nozzles.
All dies bietet dem Anwender deutliche Vorteile für viele verschiedene Anwendungen. So eignet sich der Fontänenstrahl unter anderem gut zum Hände waschen, Gesicht waschen, Zähne putzen, Becher oder dgl. mit Wasser füllen, Behältnisse ausspülen, Gegenstände abspülen etc. Durch seine kombinierte Wurfparabel- und Fächerform eignet er sich zudem auch besonders gut zum Haare waschen bzw. für Kopfinräschen und zur Bartreinigung. Durch das Fehlen eines Wasserauslaufrohres über der Waschbeckenmulde hat der Benutzer für diese Anwendungen ungehindert Platz für seinen Kopf über der Mulde.All of this offers the user significant advantages for many different applications. The fountain jet is suitable, among other things, for washing hands, washing your face, brushing your teeth, filling cups or the like with water, rinsing containers, rinsing objects, etc. Thanks to its combined parabola and fan shape, it is also particularly suitable for washing hair or for head trimming and beard cleaning. Due to the lack of a water outlet pipe above the sink recess, the user has unhindered space for his head above the recess for these applications.
Für die Wasserabgabedüsen sind beliebige herkömmliche Realisierungen verwendbar. Die Düsen können als reine Auslassöffnungen in der Waschbeckenmulde oder als eigenständige Düsenelemente z.B. in Form entsprechender Strahlaustrittsnippel realisiert sein, die in entsprechenden Düsenaufnahmeöffnungen der Mulde platziert sind. Vorteilhaft können insbesondere spezielle Fein-/Nebelstrahldüsen, wie sie in von der Anmelderin unter der Marke PowderRain vertriebenen Duscheinrichtungen verwendet sind und wie sie auch in der Offenlegungsschrift
In einer Weiterbildung der Erfindung erstreckt sich der Düsenbelegungsbereich mit seiner Streifenlänge über höchstens ein Viertel des Muldenumfangs. Dies trägt weiter zu einer erwünscht guten Lokalisierung des von der Wasserabgabevorrichtung abgegebenen Wassers innerhalb des entsprechend lokalisierten, aus dem Bündel der Einzelstrahlen bestehenden Fontänenstrahls bei. In vorteilhaften Ausführungen erstreckt sich der Düsenbelegungsbereich mit seiner Streifenlänge über mindestens ein Fünftel und höchstens ein Viertel des Muldenumfangs.In a further development of the invention, the nozzle occupancy area extends with its strip length over a maximum of a quarter of the circumference of the trough. This further contributes to a desired good localization of the water released by the water delivery device within the correspondingly localized fountain jet consisting of the bundle of individual jets. In advantageous embodiments, the nozzle occupancy area extends with its strip length over at least a fifth and at most a quarter of the circumference of the trough.
In einer Weiterbildung der Erfindung sind die Wasserabgabedüsen im Düsenbelegungsbereich in mindestens zwei Düsenreihen angeordnet, wobei die Wasserabgabedüsen einer jeweiligen Düsenreihe in Muldenumfangsrichtung versetzt zu den Wasserabgabedüsen einer jeweils benachbarten Düsenreihe angeordnet sind. Es zeigt sich, dass diese spezifische Anordnung der Wasserabgabedüsen weitergehend zu einem für die meisten Waschanwendungen optimalen Strahlbild des Fontänenstrahls beiträgt.In a further development of the invention, the water delivery nozzles are arranged in at least two rows of nozzles in the nozzle occupancy area, the water delivery nozzles of a respective row of nozzles being arranged offset in the circumferential direction of the trough in relation to the water delivery nozzles of an adjacent row of nozzles. It turns out that this specific arrangement of the water delivery nozzles further contributes to a fountain jet pattern that is optimal for most washing applications.
In einer Weiterbildung der Erfindung befindet sich der Düsenbelegungsbereich in einer nutzerseitenabgewandten Rückseitenhälfte der Waschbeckenmulde. Mit der Bezeichnung nutzerseitenabgewandte Rückseitenhälfte ist hierbei diejenige Hälfte der Waschbeckenmulde gemeint, die der vorderseitigen Hälfte der Waschbeckenmulde gegenüberliegt, wobei die Vorderseite diejenige Seite der Waschbeckenmulde bezeichnet, an welcher der Nutzer bei bestimmungsgemäßer Benutzung der Waschtischeinrichtung an die Waschbeckenmulde herantritt bzw. vor dieser steht, während auf der gegenüberliegenden Rückseite der Waschbeckenmulde bzw. des Waschtischs häufig ein Spiegel oder Spiegelschrank angeordnet ist. Dadurch richtet die Wasserabgabevorrichtung den Fontänenstrahl in Richtung auf den Benutzer zu, sei es von hinten nach vorne direkt auf ihn zu oder alternativ in einer Richtung schräg von hinten oder seitlich hinten nach vorn oder seitlich vorn. Diese Positionierung des Düsenbelegungsbereichs erweist sich in der Regel als für die allermeisten typischen Waschanwendungen besonders günstig.In a further development of the invention, the nozzle occupancy area is located in a rear half of the washbasin recess facing away from the user side. The term "back half facing away from the user side" means that half of the washbasin recess which is opposite the front half of the washbasin recess, with the front denoting the side of the washbasin recess on which the user approaches the washbasin recess or stands in front of it when using the washbasin device as intended A mirror or mirror cabinet is often arranged on the opposite back of the sink recess or washbasin. As a result, the water delivery device directs the fountain jet towards the user, be it from back to front directly towards him or alternatively in a direction obliquely from behind or sideways back to front or sideways forward. This positioning of the nozzle occupancy area generally proves to be particularly favorable for the vast majority of typical washing applications.
In einer Ausgestaltung der Erfindung weist die Waschbeckenmulde in der nutzerseitenzugewandten Vorderseitenhälfte einen Wasserablauf auf, wobei ein Fontänenstrahl-Auftreffbereich, d.h. der Bereich, in dem der Fontänenstrahl auf die Waschbeckenmulde trifft, auf einer dem Düsenbelegungsbereich zugewandten Seite des Wasserablaufs liegt. Diese Lage des Wasserablaufs relativ zum Düsenbelegungsbereich und zum Fontänenstrahl-Auftreffbereich erweist sich zur Erzielung eines gewünschten, optimalen Wasserabflusses als günstig.In one embodiment of the invention, the washbasin recess has a water drain in the front half facing the user side, with a fountain jet impact area, i.e. the area in which the fountain jet hits the washbasin recess, lying on a side of the water drain facing the nozzle occupancy area. This position of the water drain relative to the nozzle occupancy area and the fountain jet impact area proves to be favorable for achieving a desired, optimal water flow.
In einer weiteren Ausgestaltung der Erfindung ist der Wasserablauf schlitzförmig mit zu einer lateralen Fontänenstrahl-Hauptrichtungskomponente senkrechter Schlitzlängsachse gebildet. Diese Schlitzform des Wasserablaufs ist vorteilhaft auf die Form des Fontänenstrahls abgestimmt und trägt weiter zu einem optimierten Abführen des durch den Fontänenstrahl in die Waschbeckenmulde gelangenden Wassers bei.In a further embodiment of the invention, the water outlet is slot-shaped with a longitudinal slot axis perpendicular to a lateral fountain jet main direction component. This slot shape of the water drain is advantageously coordinated with the shape of the fountain jet and further contributes to an optimized removal of the water that reaches the sink recess through the fountain jet.
In einer Ausgestaltung der Erfindung sind die Wasserabgabedüsen speziell in drei in Muldenumfangsrichtung aufeinanderfolgenden Düsengruppen angeordnet, wobei die Wasserabgabedüsen einer jeweiligen Düsengruppe gleiche laterale Strahlaustrittsrichtungskomponenten aufweisen und die lateralen Strahlaustrittsrichtungskomponenten zweier seitlicher Düsengruppen um einen gleichen Schrägwinkelbetrag zur lateralen Strahlaustrittrichtungskomponente einer mittleren Düsengruppe hin geneigt verlaufen. Dies ergibt einen Fontänenstrahl mit sehr vorteilhaftem, symmetrischem Strahlbild. Mit der Bezeichnung laterale Strahlaustrittsrichtungskomponente ist hierbei diejenige Richtungskomponente der durch die Düsen bestimmten Strahlaustrittsrichtungen der Einzelstrahlen gemeint, die sich für die laterale, d.h. horizontale, Projektion der Strahlaustrittsrichtung senkrecht zur vertikalen Höhenrichtung ergibt.In one embodiment of the invention, the water delivery nozzles are specifically arranged in three nozzle groups which follow one another in the circumferential direction of the trough, the water delivery nozzles of a respective nozzle group having the same lateral jet exit direction components and the lateral jet exit direction components of two lateral nozzle groups being inclined towards the lateral jet exit direction component of a central nozzle group by an equal oblique angle amount. This results in a fountain jet with a very advantageous, symmetrical jet pattern. The term lateral jet exit direction component means that directional component of the jet exit directions of the individual jets determined by the nozzles, which results for the lateral, i.e. horizontal, projection of the jet exit direction perpendicular to the vertical height direction.
In einer Weiterbildung der Erfindung beinhaltet die Waschtischeinrichtung einen Wasserverteilerkörper an einer Unterseite der Waschbeckenmulde im Düsenbelegungsbereich. Der Wasserverteilerkörper weist eine sich über die Länge des Düsenbelegungsbereichs erstreckende Wasserzufuhrkammer und eine von der Wasserzufuhrkammer durch eine Trennwand getrennte und mit der Wasserzufuhrkammer über eine Mehrzahl von Durchlassöffnungen in der Trennwand in Fluidverbindung stehende Wasserverteilkammer auf. An den Wasserverteilerkörper sind die Wasserabgabedüsen angekoppelt, wobei die Wasserabgabedüsen über seitliche Einlassöffnungen mit der Wasserverteilkammer in Fluidverbindung stehen. Dies stellt eine vorteilhafte Realisierung für die Wasserzufuhr zu den in der Waschbeckenmulde angeordneten Wasserabgabedüsen dar. Durch die Auftrennung in die Wasserzufuhrkammer und die mit dieser über die Durchlassöffnungen in Fluidverbindung stehende Wasserverteilkammer kann das Wasser vergleichsweise gleichmäßig und folglich auch mit gleichen Druckverhältnissen den verschiedenen Wasserabgabedüsen zugeführt werden. Dadurch sind die Wasserabgabedüsen wiederum problemlos in der Lage, gleichartige Einzelstrahlen abzugeben, d.h. Einzelstrahlen mit im Wesentlichen gleicher Wurfhöhe und Wurfweite ihrer Wurfparabelform.In a further development of the invention, the washbasin device includes a water distributor body on an underside of the washbasin recess in the nozzle occupancy area. The water distributor body extends over the length of the Nozzle occupancy area extending water supply chamber and a water distribution chamber separated from the water supply chamber by a partition and in fluid communication with the water supply chamber via a plurality of passage openings in the partition. The water delivery nozzles are coupled to the water distribution body, the water delivery nozzles being in fluid communication with the water distribution chamber via side inlet openings. This represents an advantageous implementation for the water supply to the water dispensing nozzles arranged in the sink recess. By separating into the water supply chamber and the water distribution chamber in fluid communication with it via the passage openings, the water can be supplied to the various water dispensing nozzles comparatively evenly and consequently with the same pressure conditions . As a result, the water delivery nozzles are in turn easily able to emit similar individual jets, ie individual jets with essentially the same throw height and throw distance of their throw parabola shape.

Die in den Figuren veranschaulichte Waschtischeinrichtung umfasst einen Waschtisch 1 mit einer Waschbeckenmulde 2 und eine Wasserabgabevorrichtung 3, die zur Abgabe von Wasser in Form eines aus Einzelstrahlen bestehenden Fontänenstrahls ausgelegt ist und eine Mehrzahl von Wasserabgabedüsen 4 aufweist. Die Wasserabgabedüsen 4 sind in der Waschbeckenmulde 2 zur Abgabe der Einzelstrahlen in zugehörigen Einzelstrahlrichtungen von der Waschbeckenmulde 2 aus schräg nach oben und wieder in die Waschbeckenmulde 2 zurück angeordnet. Die
Die Wasserabgabedüsen 4 sind innerhalb eines streifenförmigen Düsenbelegungsbereichs 6 mit sich in Muldenumfangsrichtung erstreckender Streifenlänge DL und dazu senkrechter Streifenhöhe DH angeordnet, wobei seine Streifenlänge DL größer als seine Streifenhöhe ist und er sich mit seiner Streifenlänge über höchstens den halben Muldenumfang erstreckt. Die Streifenlänge DL, die in einer normalen Gebrauchslage der Waschtischeinrichtung in einer Horizontalebene verläuft, und zwar entsprechend der Form der Mulde 2 z.B. mit einem gebogenen Verlauf, und die dazu senkrechte Streifenhöhe DH sind exemplarisch in den
In vorteilhaften Ausführungen erstreckt sich der Düsenbelegungsbereich 6 wie im gezeigten Beispiel mit seiner Streifenlänge DL über höchstens ein Viertel des Muldenumfangs, z.B. über eine Länge, die zwischen einem Fünftel und einem Viertel des Muldenumfangs liegt. Die Streifenhöhe DH ist in vorteilhaften Ausführungen um ein Mehrfaches kleiner als die Streifenlänge DL, z.B. um mindestens den Faktor 5 oder mindestens den Faktor 10 oder mindestens den Faktor 15 oder mindestens den Faktor 20 oder mindestens den Faktor 25 kleiner.In advantageous embodiments, the
In vorteilhaften Ausführungen ist die Waschbeckenmulde 2 wie im gezeigten Beispiel kreisförmig. In alternativen Ausführungen besitzt sie eine andere Form, z.B. oval oder viereckig oder eine beliebige andere, z.B. unregelmäßige Form.In advantageous embodiments, the
In vorteilhaften Ausführungen sind wie im gezeigten Ausführungsbeispiel die Wasserabgabedüsen 4 im Düsenbelegungsbereich 6 in mindestens zwei Düsenreihen 71, 72 angeordnet, wobei die Wasserabgabedüsen 4 einer jeweiligen Düsenreihe 71, 72 in Muldenumfangsrichtung versetzt zu den Wasserabgabedüsen 4 einer jeweils benachbarten Düsenreihe 71, 72 angeordnet sind.In advantageous embodiments, as in the exemplary embodiment shown, the
In vorteilhaften Realisierungen sind wie im gezeigten Beispiel die Wasserabgabedüsen 4 jeweils benachbarter Düsenreihen 71, 72 mittig versetzt angeordnet, d.h. jede Düse 4 der einen Düsenreihe liegt in Muldenumfangsrichtung gesehen mittig zwischen zwei zueinander benachbarten Düsen 4 der anderen Düsenreihe. Mit anderen Worten sind die Düsen 4 in den benachbarten Düsenreihen 71, 72 relativ zueinander um den halben Düsenabstand der Düsen 4 innerhalb der jeweiligen Düsenreihe 71, 72 versetzt angeordnet. In alternativen Ausführungen ist ein außermittiger Versatz gewählt.In advantageous implementations, as in the example shown, the
Im gezeigten Ausführungsbeispiel beinhaltet der Düsenbelegungsbereich 6 genau zwei Düsenreihen 71, 72, in alternativen Ausführungen beinhaltet er mehr als zwei Düsenreihen, z.B. zwischen drei und acht Düsenreihen.In the exemplary embodiment shown, the
In vorteilhaften Ausführungsformen befindet sich wie im gezeigten Beispiel der Düsenbelegungsbereich 6 in einer nutzerseitenabgewandten Rückseitenhälfte 2a der Waschbeckenmulde 2. Diese Rückseitenhälfte 2a liegt einer nutzerseitenzugewandten Vorderseitenhälfte 2b der Waschbeckenmulde 2 gegenüber. Die nutzerseitenzugewandte Vorderseitenhälfte 2b der Mulde 2 ist einer Vorderseite 8 der Mulde 2 und des Waschtischs 1 insgesamt zugewandt, die bei bestimmungsgemäßer Nutzung der Waschtischeinrichtung die Nutzerseite bildet, d.h. diejenige Seite, an die der Benutzer herantritt, wenn er die Waschtischeinrichtung benutzen will. Dieser Vorderseite 8 liegt eine Rückseite 9 der Mulde 2 und des Waschtischs 1 gegenüber, an der sich in typischen Waschtischeinrichtungen z.B. ein Spiegel oder Spiegelschrank befindet, was hier nicht weiter interessiert und daher nicht gezeigt ist. In alternativen Ausführungen befindet sich der Düsenbelegungsbereich 6 mindestens teilweise auch in der nutzerseitenzugewandten Vorderseitenhälfte 2b der Waschbeckenmulde 2, d.h. mit einem entsprechenden Teil näher zur Vorderseite 8 als zur Rückseite 9 der Mulde 2 bzw. des Waschtischs 1.In advantageous embodiments, as in the example shown, the
In vorteilhaften Ausführungen weist die Waschbeckenmulde 2 wie im gezeigten Beispiel in der nutzerseitenzugewandten Vorderseitenhälfte 2b einen Wasserablauf 10 auf. Wie beispielsweise aus
In einer vorteilhaften Realisierung ist der Wasserablauf 10 wie im gezeigten Ausführungsbeispiel schlitzförmig mit zu einer lateralen Fontänenstrahl-Hauptrichtungskomponente FH senkrechter Schlitzlängsachse Ls gebildet. Mit der Bezeichnung laterale Fontänenstrahl-Hauptrichtungskomponente ist hierbei diejenige Richtungskomponente FH gemeint, entlang der sich in horizontaler Projektion der Fontänenstrahl 5 hauptsächlich ausbreitet. Im gezeigten Beispiel ist dies die Richtung von hinten nach vorn, d.h. die Richtung von der Rückseite 9 zur Vorderseite 8 der Mulde 2 bzw. des Waschtischs 1, wie in den
Es versteht sich, dass Strahlaustrittsrichtungen Sij der Einzelstrahlen der Wasserabgabedüsen 4 in der Regel der Längsachse der jeweiligen Wasserabgabedüse 4 entsprechen und eine Vertikalkomponente nach oben sowie eine nach vorn und/oder nach senkrecht dazu seitlich quer verlaufende Horizontalkomponente aufweisen. In den
Die Wasserabgabedüsen 4 sind, wie gezeigt, in wenigstens zwei in Muldenumfangsrichtung aufeinanderfolgenden Düsengruppen 41, 42 mit jeweils mehreren der Wasserabgabedüsen 4 angeordnet. Dabei ist eine maximale Differenz von Strahlaustrittsrichtungen der Wasserabgabedüsen 4 einer jeweiligen Düsengruppe, z.B. der Düsengruppe 41 oder der Düsengruppe 42, geringer als eine minimale Differenz der Strahlaustrittsrichtungen der Wasserabgabedüsen 4 zweier benachbarter Düsengruppen, wie der Düsengruppen 41 und 42. Mit anderen Worten, wenn die Strahlaustrittsrichtung einer i-ten einer Anzahl n von Wasserabgabedüsen 4 einer j-ten Düsengruppe einer Anzahl m von Düsengruppen 41, ..., 4m mit Sij bezeichnet wird, wobei die Anzahl n von Wasserabgabedüsen 4 für die verschiedenen Düsengruppen 41, 42, ... unterschiedlich sein kann, ist der Maximalwert der Differenz Slq-Spq, mit 1≤l≤ n und 1≤p≤n, der Strahlaustrittsrichtungen der Wasserabgabedüsen 4 einer jeden Düsengruppe 4q mit 1≤q≤m, geringer als ein Minimalwert der Differenz Slt-Spq der Strahlaustrittsrichtungen der Wasserabgabedüsen 4 zweier benachbarter Düsengruppen 4t, 4q, mit t=q+1, in einer sortierten Bezeichnung der in Muldenumfangsrichtung aufeinanderfolgenden Düsengruppen 41, 42, ... Dadurch lässt sich mit vergleichsweise geringem Aufwand ein vorteilhaftes Strahlbild für den Fontänenstrahl 5 erzeugen.The
In entsprechenden Ausführungen sind die Wasserabgabedüsen 4 wie im gezeigten Beispiel in drei in Muldenumfangsrichtung aufeinanderfolgenden Düsengruppen 41, 42, 43 angeordnet, wobei die Wasserabgabedüsen 4 einer jeweiligen Düsengruppe gleiche laterale Strahlaustrittsrichtungskomponenten SHj aufweisen und die lateralen Strahlaustrittsrichtungskomponenten zweier seitlicher Düsengruppen 41, 43 um einen gleichen Schrägwinkelbetrag WD zur lateralen Strahlaustrittsrichtungskomponente einer mittleren Düsengruppe 42 hin geneigt verlaufen. Mit lateraler Strahlaustrittsrichtungskomponente ist hierbei die sich in horizontaler Projektion ergebende Komponente der Strahlaustrittsrichtung der jeweiligen Wasserabgabedüse 4 und damit des von ihr abgegebenen Einzelstrahls 11 gemeint.In corresponding embodiments, the

Dadurch ergibt sich für den resultierenden Fontänenstrahl 5 ein konvergentes Strahlverhalten der Einzelstrahlen bzw. ein Verlauf des Fontänenstrahls 5, der ausgehend von der Wasserabgabevorrichtung 3 bis zu einem etwa mittleren Bereich der Waschbeckenmulde 2 konvergiert, wobei der Fontänenstrahl 5 in diesem Bereich auch seine maximale Höhe erreicht. Im weiteren Verlauf behält der Fontänenstrahl 5 bis zu seinem Auftreffbereich FA auf der Mulde 2 eine Strahlbündelform und/oder eine im Wesentlichen konstante Strahlbreite FB bei, wie sie in den
Da somit in diesem exemplarischen Beispiel die Strahlaustrittsrichtungen Sij aller Wasserabgabedüsen 4 einer jeweiligen Düsengruppe gleich sind, ist die maximale Differenz der Strahlaustrittsrichtungen Sij der Wasserabgabedüsen 4 einer jeweiligen Düsengruppe 41, 42, 4s gleich null. Denn diese Differenz ist sowohl für die erste Düsengruppe 41 als auch die zweite Düsengruppe 42 und die dritte Düsengruppe 43 jeweils gleich null, so dass auch die maximale Differenz bei Betrachtung aller Düsengruppen 41 bis 43 gleich null ist. Hingegen unterscheiden sich die Strahlaustrittsrichtungen Sij der Wasserabgabedüsen 4 der beiden benachbarten Düsengruppen 41 und 42 in horizontaler Projektion um den Schrägwinkelbetrag WD, und ebenso unterscheiden sich die Strahlaustrittsrichtungen Sij der Wasserabgabedüsen 4 der zwei benachbarten Düsengruppen 42 und 43 um den im gewählten exemplarischen Beispiel gleichen Schrägwinkelbetrag WD, so dass auch die minimale Differenz in horizontaler Projektion gleich dem Schrägwinkelbetrag WD und damit größer als null und mithin größer als die maximale Differenz der Strahlaustrittsrichtungen Sij der Wasserabgabedüsen 4 jeder Düsengruppen 41 bis 4s untereinander ist.Since in this exemplary example the jet exit directions Sij of all
Wie anhand der
In alternativen Ausführungen sind die Wasserabgabedüsen 4 in mindestens einer der drei Düsengruppen 41, 42, 43 mit zwei oder mehr unterschiedlichen Strahlaustrittsrichtungen statt sämtlich mit gleicher Strahlaustrittsrichtung angeordnet, z.B. die Wasserabgabedüsen mindestens einer der Düsengruppen 41, 42, 4a derart, dass sich als von dieser Düsengruppe 41 und/oder 42 und/oder 43 abgegebener Strahlstreifen ein leicht konvergenter oder leicht divergenter Strahl anstelle eines Strahls mit gleichbleibender Breite ergibt. In weiteren alternativen Ausführungen sind die Wasserabgabedüsen 4 in mehr als drei in Muldenumfangsrichtung aufeinanderfolgenden Düsengruppen mit jeweils untereinander gleicher oder jedenfalls im Vergleich mit Düsen einer anderen Gruppe weniger unterschiedlicher Strahlaustrittsrichtung angeordnet.In alternative embodiments, the
Für die Wasserzufuhr zur Wasserabgabeeinrichtung besitzt die Waschtischeinrichtung in entsprechenden vorteilhaften Ausführungen wie im gezeigten Beispiel einen Wasserverteilerkörper 12 an einer Unterseite der Waschbeckenmulde 2 im Düsenbelegungsbereich 6. Die
In vorteilhaften Realisierungen ist der Wasserverteilerkörper 12 als einteiliges Bauteil gefertigt, an dem die Wasserabgabedüsen 4 montiert sind, z.B. als einzelne Düsenelemente, wie PowderRain-Düsenelemente. Die Durchlassöffnungen 16 sind mit vorzugsweise im Wesentlichen gleichmäßigen Abständen voneinander in der Trennwand 14 vorgesehen, z.B. als in einer Reihe nebeneinander liegende und voneinander beabstandete Bohrungen. Der Wasserverteilerkörper 12 entspricht in seinem Längsverlauf zweckmäßig demjenigen des Düsenbelegungsbereichs 6, so dass er im gezeigten Beispiel entsprechend dem Düsenbelegungsbereich 6 bogenförmig verläuft und seine Längsausdehnung im Wesentlichen der Streifenlänge DL des Düsenbelegungsbereichs 6 entspricht. Zur Aktivierung und Deaktivierung der Wasserzufuhr zum Wasserverteilerkörper können beliebige, dem Fachmann hierfür an sich bekannte herkömmliche Mittel dienen, was hier folglich keiner weiteren Erläuterungen bedarf, z.B. unter Verwendung mechanisch oder elektrisch ansteuerbarer Absperrventile, die in einer Wasserzufuhrleitung zum Wasserverteilerkörper angeordnet sind.In advantageous implementations, the
Wie die gezeigten und die weiteren oben erläuterten Ausführungsbeispiele deutlich machen, stellt die Erfindung eine Waschtischeinrichtung mit deutlichen Vorteilen für den Anwender zur Verfügung. Das Wasser wird als Fontänenstrahl durch in der Waschbeckenmulde angeordnete Wasserabgabedüsen bereitgestellt. Eine übliche sanitäre Auslaufarmatur mit über der Mulde endendem Auslaufrohr kann dadurch entfallen. Dies hat Vorteile für die Benutzbarkeit der Waschtischeinrichtung, da keine Rücksicht auf ein Auslaufrohr einer Auslaufarmatur genommen werden muss. Zudem kann der Waschtisch insgesamt mit sehr planer Oberfläche gestaltet werden, was das Reinigen der Waschtischeinrichtung deutlich erleichtern kann. Auch der Wegfall einer typischerweise am Waschtisch im Bereich der Waschbeckenmulde montierten Auslaufarmatur mit über der Mulde endendem Auslaufrohr erleichtert das Reinigen der Waschtischeinrichtung.As the exemplary embodiments shown and the other exemplary embodiments explained above make clear, the invention provides a washbasin device with clear advantages for the user. The water is provided as a fountain jet by water delivery nozzles arranged in the sink recess. This eliminates the need for a standard sanitary outlet fitting with an outlet pipe ending above the trough. This has advantages for the usability of the washbasin device, since there is no need to take into account an outlet pipe of a outlet fitting. In addition, the wash basin can be designed with a very flat surface, which can make cleaning the wash basin equipment much easier. The elimination of an outlet fitting typically mounted on the washbasin in the area of the sink recess with an outlet pipe ending above the recess also makes cleaning the washbasin facility easier.
