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 distributor body 12 is manufactured as a one-piece component on which the water delivery nozzles 4 are mounted, for example as individual nozzle elements, such as PowderRain nozzle elements.
  • the passage openings 16 are provided in the partition wall 14 at preferably substantially uniform distances from one another, for example as bores lying next to one another in a row and spaced apart from one another.
  • the water distributor body 12 expediently corresponds in its longitudinal course to that of the nozzle occupancy area 6, so that in the example shown it runs in an arc shape corresponding to the nozzle occupancy area 6 and its longitudinal extent essentially corresponds to the strip length D L of the nozzle occupancy area 6.
  • 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.
  • 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.
