Definitions

  • the invention relates to a sanitary outlet unit with a jet regulator which has an inflow-side jet splitter with splitter openings which split the inflowing water into a plurality of individual jets, and which has an outflow-side hole structure made up of a plurality of spray openings through which the water from the jet regulator is shaped individual spray jets exits, as well as with an outlet mouthpiece, which has a connection thread at least on its inflow-side peripheral portion, with which the outlet mouthpiece can be screwed to a mating thread on the water outlet of a sanitary outlet fitting.
  • Jet regulators have also already been created which allow the water flowing out at the water outlet of a sanitary outlet fitting to emerge in separate individual jets.
  • Some of these outlet units of the type mentioned above, also referred to as spray jet regulators have an outlet mouthpiece that has a connection thread on the inside or outside of its inflow-side circumferential portion, with which the outlet mouthpiece can be screwed to a mating thread on the water outlet of a sanitary outlet fitting.
  • These known outlet units have an inflow-side jet splitter which divides the inflowing water into a plurality of individual jets before these individual jets flow inside the outlet mouthpiece to an outflow-side hole structure which has a plurality of Has spray openings through which the water exits the jet regulator in the form of individual spray jets.
  • the aim is to give different sanitary outlet fittings from different manufacturers a characteristic shape.
  • the outlet fittings are also designed in the area of their water outlet, deviating from the usual circular outlet cross-section, on the outer circumference with a square or otherwise non-circular cross-section.
  • One problem here is to mount the outlet mouthpiece of a sanitary outlet unit on this non-circular water outlet of the sanitary outlet fitting by means of a screw connection, which regularly requires a round cross-section of the two components to be connected, at least in the area of the screw connection.
  • One inventive solution to this problem in the case of the sanitary outlet unit of the type mentioned at the outset consists in particular in that the edge-side spray openings of the downstream hole structure are arranged outside a circular area projected axially in the direction of the hole structure, which form the splitter openings of the upstream jet splitter.
  • a further inventive solution to this problem in the case of the sanitary outlet unit of the type mentioned at the outset can consist in particular in that the outlet mouthpiece has a triangular, square or polygonal cross-section on the outer circumference, and that the through the corner points of the hole pattern formed by the spray openings delimit a uniform triangle, square or polygon.
  • the sanitary outlet unit according to the invention has a jet regulator which has an inflow-side jet splitter which divides the inflowing water into a plurality of individual jets in the interior of the jet regulator.
  • the water divided and swirled in this way in the jet regulator flows to a perforated structure which forms the outflow side of the jet regulator, where the water exits the outlet unit.
  • This hole structure has a plurality of spray openings through which the water exits the jet regulator in the form of individual spray jets.
  • the jet regulator is arranged in an outlet mouthpiece, which has a connection thread on the inside or outside of its inflow-side circumferential part, with which the outlet mouthpiece can be screwed to an external or internal thread on the water outlet of the sanitary outlet fitting.
  • the outlet mouthpiece In order to be able to adapt the shape of the outlet mouthpiece in its outer circumference to the non-circular outlet cross-section of a sanitary outlet fitting, the outlet mouthpiece has, for example, a triangular, square or polygonal cross-section on the outer circumference.
  • one solution according to the invention provides that the edge-side spray openings of the downstream hole structure are arranged outside a circular area projected axially in the direction of the hole structure, which circular area forms the splitter openings of the upstream jet splitter.
  • the further proposal of the invention provides that the lines running through the corner points of the hole pattern formed by the spray openings delimit a uniform triangle or square or a polygon.
  • the water jet emerging in individual spray jets thus has a triangular, square or polygonal jet cross section and is thus uniform with respect to the outer circumference of the outlet mouthpiece. Since this non-circular jet cross-section of the exiting water is formed by the individual spray jets, it is ensured that the emerging water retains its non-circular, i.e. triangular, square or polygonal outlet jet pattern even over a longer distance, without this water necessarily becoming an unsteady round jet cross-section tried to change.
  • the spray openings are arranged on the inlet side in parallel rows that are spaced apart from one another. In this way, the spray jets can be distributed approximately evenly over the jet cross-section.
  • a structurally simple and easy to manufacture embodiment according to the invention provides that the jet splitter is designed as a perforated plate which has a plurality of splitter openings that are spaced apart from one another.
  • splitter openings of the jet splitter designed as a perforated plate are arranged in concentric hole circles with respect to one another.
  • the jet splitter acts as a diffuser is formed, which has a pot-shaped diffuser insert with a pot bottom serving as a baffle surface, and which are provided on the pot circumference of the pot-shaped diffuser insert in the circumferential direction spaced apart from each other splitting openings which open into an annular gap narrowing in the flow direction.
  • the jet regulator is designed as a diffuser, the inflowing water can also be easily divided into the individual jets in the low-pressure range, which are then transformed into the spray jets in the outflow-side hole structure.
  • This diffuser has a pot-shaped diffuser insert which has a pot bottom which serves as a baffle for the inflowing water.
  • the water flowing to the jet splitter is slowed down and deflected radially outwards, where splitter openings spaced apart from one another in the circumferential direction are provided on the circumference of the cup-shaped diffuser insert.
  • These splitting openings open into an annular gap which narrows in the direction of flow. Since the annular gap narrows in the direction of flow, a negative pressure is generated on the outflow side of this annular gap according to Bernoulli's equation, which, if necessary, can also be used in a ventilated jet regulator to suck in ambient air.
  • a preferred embodiment according to the invention provides that the diffuser insert is inserted from the inflow side into a diffuser ring of the diffuser, preferably releasably, and that the diffuser insert and the diffuser ring delimit the annular gap between them.
  • the non-circular external appearance of the water emerging from the outlet unit according to the invention is determined in particular by the spray openings which form the corner points of this hole pattern. With it this formative effect of the spray jets emerging in the corner areas is additionally favored, it is advantageous if the spray openings arranged in the corner areas of the hole pattern of the hole structure have a larger clear flow cross-section compared to the other spray openings of the hole structure.
  • a uniform distribution of the spray jets in the jet cross-section of the overall jet generated by them favors when the longitudinal axes of the spray openings arranged in a central area of the perforated structure are approximately coaxial with the longitudinal axis of the jet regulator, and when the remaining spray openings are increasingly angled outwards towards the outer area of the perforated structure.
  • a uniform distribution of the spray jets over the entire jet cross-section of the exiting water is already promoted in the interior of the jet regulator of the outlet unit according to the invention if the jet splitter has a round outer circumference.
  • the diffuser insert and / or the diffuser ring have a round outer circumference.
  • a structurally simple and comparatively easy to manufacture embodiment according to the invention provides that the jet regulator has a jet regulator housing which is pot-shaped at least in its downstream partial area is formed, and that the pot bottom of this pot-shaped housing portion is formed by the hole structure having the spray openings.
  • the jet regulator used in the outlet unit according to the invention with as little effort as possible, even if the jet regulator housing still has a round cross-section in the area of the screw connection of the outlet unit according to the invention, which in the area of the outflow-side hole structure into a triangular, square or polygonal cross-section passes over, it is advantageous if the jet regulator has an at least two-part jet regulator housing and has at least one inflow-side and at least one cup-shaped outflow-side housing part.
  • a preferred embodiment according to the invention provides that the at least one inflow-side housing part can be inserted from the inflow side up to a first insertion stop in the outlet mouthpiece, and that the at least one outflow-side housing part can be inserted from the outflow side up to a second insertion stop into the outlet mouthpiece can be used.
