Definitions

  • the invention relates to an aerator with an aerator housing which can be inserted into the water outlet of a sanitary outlet fitting and which has a lattice or network structure on the outlet side made up of intersecting guide walls which delimit outflow openings between them.
  • Such jet regulators usually have a cylindrical jet regulator housing, which can be detachably mounted on the water outlet of a sanitary outlet fitting, which has a complementary shape in the clear cross section, in order to shape the water exiting there into a homogeneous, non-splashing and possibly also sparkling-soft water jet.
  • a lattice or network structure of crossing guide walls is provided, which is intended to act as a flow straightener on the water exiting there.
  • a jet regulator is already known, the jet regulator housing of which is designed as an insertable cartridge that can be inserted into the outlet end of a sanitary outlet fitting.
  • an external thread is provided on the outer circumference of the jet regulator housing, which can be releasably connected to a complementary internal thread on the inner circumference at the outlet end of the sanitary outlet fitting.
  • the previously known aerator can be screwed so deep into the outlet end of the outlet fitting that its outlet face is essentially flush with the outlet face of the outlet fitting.
  • outlet fitting is not mounted directly on the ceramic washbasin, but next to it, for example on a level that does not have a water drain, annoying puddles of water can often form there. These puddles of water even lead to greater damage if the plane carrying the outlet fitting is made of wood, wood veneer or another water-sensitive material for design reasons.
  • an aerator has therefore also been created which, with its cylindrical insert housing, can be inserted directly into the water outlet of a sanitary outlet fitting or with the aid of an intermediate holder and held there in a detachable manner (cf. DE 10 2008 038 730 A1 ).
  • the outflow-side end face of the previously known aerator is defined by a peripheral, sleeve-shaped ring wall on the insert housing or on the intermediate holder , which as one over the outlet end of the sanitary outlet fitting protruding drip edge is designed.
  • outlet fittings In order to increase the variety of designs and to let the water flow out not as an outlet jet with a round cross-section, but initially as a flat jet band, outlet fittings have also been created whose water outlet has a non-round outlet cross-section and, in particular, a wide, rectangular outlet cross-section with long longitudinal and in contrast, has short side walls. There is also the problem with these outlet fittings that even after the outlet valve has been closed, a certain amount of water continues to flow and then drip off at the outlet end of the outlet fitting or run off there on the outer circumference of the outlet fitting and then over time leave traces of limescale and rust there that impair the outlet fitting.
  • the object is therefore to create an aerator that reliably prevents water droplets from spilling onto the outer circumference of the sanitary outlet fitting, even in the case of such outlet fittings with a non-circular outlet cross section.
  • the solution according to the invention consists in particular in that the jet regulator housing has a non-circular housing cross section and has longitudinal housing walls which have a greater longitudinal housing extension compared to the depth of the housing cross section, and that the jet regulator housing has a water-guiding apron which in the outflow direction the lattice or mesh structure protrudes and which extends in the circumferential direction of the housing only over a portion of the circumference of the housing.
  • the invention relates to an aerator with an aerator housing which can be inserted into the water outlet of a sanitary outlet fitting and which has a lattice or network structure on the outlet side made up of intersecting guide walls which delimit outflow openings between them.
  • a water-guiding apron is provided on the aerator housing of the aerator according to the invention, which projects over the lattice or mesh structure in the outflow direction and which extends in the circumferential direction of the housing over only a portion of the circumference of the housing.
  • this water-guiding apron is designed like an apron and only extends over a portion of the housing circumference in the circumferential direction of the housing, the relative position of the aerator housing in the circumferential direction in relation to the water outlet of the outlet fitting must be determined.
  • the jet regulator housing has a non-round housing cross-section, with the longitudinal housing walls having a greater longitudinal housing extension compared to the depth of the housing cross-section. Any residual water that may be left after the outlet valve is closed can drip off the water-guiding apron.
  • this water flow apron can change the band-shaped design of the Influence outlet jet additionally favorable.
  • the water-guiding apron is provided at least on the longitudinal wall of the jet regulator housing facing away from or towards the user in the position of use.
  • the water-guiding apron is provided on the longitudinal wall of the jet regulator housing facing away from the user in the position of use. This prevents a residual amount of water still flowing inside the outlet fitting from gravitationally transferring to the outer circumference of the outlet fitting and leading to drips or traces of limescale there.
  • the water-guiding apron is provided on the longitudinal wall of the aerator housing facing the user in the position of use, unwanted splashing of the outflowing water jet is counteracted, which could otherwise lead to wetting of the outlet fitting in the area of its water outlet in drops on the outer circumference.
  • the water-guiding apron can be limited to the longitudinal wall of the jet regulator housing facing away from the user in the position of use or towards it.
  • preferred embodiments according to the invention provide that the water-guiding apron runs on both sides over the housing corner areas connecting the longitudinal housing wall with the housing transverse or side walls. This also prevents water from spilling over drop by drop in the corner areas of the longitudinal and transverse walls of the jet regulator housing.
  • a preferred development according to the invention which is characterized by a favorable water flow of the water jet emerging in the form of a strip and which effectively prevents a residual amount of water from escaping onto the outside of the outlet fitting, provides that the water flow apron is connected via the longitudinal wall of the housing to the housing Housing corner areas connecting transverse walls also extends at least up to approximately a longitudinal center plane of the housing.
  • a structurally simple, functionally effective embodiment according to the invention that can be produced with comparatively little effort provides that the water-guiding apron is designed as a partial area of the longitudinal housing wall facing away from or towards the user that protrudes over the lattice or net structure. Since the water-guiding apron is not formed and/or manufactured as a separate component from the housing wall, and since the water-guiding apron is designed as a partial area of the longitudinal wall of the aerator housing that protrudes beyond the lattice or mesh structure, the aerator housing can be equipped with the device provided according to the invention Water flow apron also be integrally formed.
  • the jet regulator is designed as a rectangular or flat jet regulator.
  • a simple and preferred embodiment according to the invention provides that the jet regulator has a peripheral wall of the housing, the longitudinal housing walls of which are connected to one another via the transverse housing walls.
  • the housing transverse walls have a rounded or arc-shaped cross section.
  • the jet regulator housing essentially has a rectangular or oval housing cross section.
  • the longitudinal housing wall facing away from the user has, at least in a partial area, a recess which is set back in relation to the transverse walls of the housing adjoining on both sides and which is designed to be open towards the outlet end face.
  • This recessed recess can delimit a ventilation and/or insertion channel that is provided in this area between the outer circumference of the jet regulator housing and the inner circumference of the water outlet of the outlet fitting.
  • a preferred embodiment according to the invention provides that in the region of the set-back depression of the longitudinal wall of the housing there is at least one latching lug or similar tool gripping surface for detachable connection with an extraction tool.
  • a fastening screw can be used in the area of the set-back depression of the longitudinal wall of the housing, by means of which the aerator housing can be fixed in the water outlet. Since the recessed recess is located in a portion of the longitudinal wall of the housing facing away from the user, and since the fastening screw is screwed in in the area of this recessed recess, the screw connection between the outlet fitting and the jet regulator housing that is effected by means of the fastening screw is not readily visible to the user.
  • a pull-out stop preferably in the shape of an arc of a circle, protrudes beyond the set-back depression of the longitudinal wall of the housing in order to apply the at least one fastening screw.
  • This extraction stop facilitates the application of an extraction tool in the insertion channel provided between the jet regulator housing and the inner circumference of the outlet fitting.
  • this pull-out stop also makes it easier to attach the fastening screw to the longitudinal wall of the aerator housing.
  • the jet regulator housing has at least one circumferential annular groove on the outer circumferential side, in which annular groove a circumferential ring seal is arranged.
  • an aerator 1 is shown with an aerator housing 2 which can be inserted into the water outlet 3 of a sanitary outlet fitting 4 .
  • the jet regulator housing 2 has a lattice structure 5 on the outlet side made up of guide walls 6, 7 crossing one another, which delimit outflow openings 8 between them.
  • a water-guiding apron 9 is provided on the aerator housing 2 of the aerator 1 shown here, which extends over the grating in the outflow direction - or network structure 5 protrudes and which extends in the housing circumferential direction only over a portion of the housing circumference of the jet regulator housing 2.
  • the relative position of the jet regulator housing 2 in the circumferential direction in relation to the water outlet 3 is Outlet fitting 4 set.
  • the jet regulator housing 2 has a non-circular housing cross-section and has longitudinal housing walls 10, 11, which have a greater housing longitudinal extension compared to the depth of the housing cross-section. A residual amount of water that may still be running after the outlet valve of the outlet fitting 4 has been closed can drip off on the water-guiding apron 9 .
  • the water-guiding apron 9 can additionally favorably influence the band-shaped design of the outflowing water jet.
  • the water-guiding apron 9 is primarily provided on the longitudinal wall 11 of the jet regulator housing 2 facing away from the user in the position of use, the water-guiding apron 9 protruding slightly beyond the outlet end of the outlet fitting 4 is not readily apparent to the user. From a comparison of 1 , 2 and 7 it is clear that the water-guiding apron 9 runs on both sides over the housing corner regions 14, 15 connecting the longitudinal housing wall 11 to the housing transverse walls 12, 13.
  • the housing transverse walls 12, 13 have a rounded or arc-shaped cross section.
  • the jet regulator housing 2 of the jet regulator 1 shown here essentially has a rectangular housing cross section.
  • the longitudinal housing wall 11 facing away from the user has in a partial area a recess 16 set back in relation to the housing transverse walls 12, 13 adjoining on both sides and which is open towards the outlet end face of the jet regulator housing 2 is trained.
  • at least one locking lug 17 or a similar tool gripping surface can be provided for detachable connection with an extraction tool.
  • the jet regulator housing 2 inserted into the water outlet 3 of the outlet fitting 4 in the position of use can also be removed again if necessary and, for example, replaced.
  • a fastening screw 18 can also be attached, by means of which the aerator housing 2 can be fixed in the water outlet 3 .
  • a screw opening 19 with an internal thread is provided in the water outlet 3 of the outlet fitting 4 , into which the external thread of the fastening screw 18 can be screwed until the threaded shank of this fastening screw 18 engages with the jet regulator housing 2 .
  • a pull-out stop 20 in the shape of a circular arc projects beyond the set-back depression 16 in the longitudinal wall 11 of the housing. This pull-out stop 20 prevents unintentional detachment of the jet regulator housing 2 from the water outlet 3 of the outlet fitting 4 when this pull-out stop 20 engages behind the fastening screw 18 resting on the jet regulator housing 2 .
  • the aerator 1 serves to allow the water flowing out of the water outlet 3 of the outlet fitting 4 to exit with an initially flat or band-shaped jet cross-section, with the outlet jet being shaped as homogeneously as possible and without splashing.
  • an attachment sieve 21 is held in a detachably latchable manner on the inlet-side end face of the jet regulator 1 .
  • a Perforated plate-trained jet splitter 22 is provided, which divides the water flowing through into a plurality of individual jets.
  • a ventilation opening 23 is provided in the direction of flow immediately behind the jet splitter 22 and preferably passes through the longitudinal wall 11 of the housing in the region of the depression 16 . Since the water flowing through the splitter openings of the jet splitter 20 creates a negative pressure on the outflow side of the jet splitter 22, ambient air is sucked in via the ventilation channel remaining between the recess 16 of the jet regulator housing 2 and the adjacent inner peripheral wall of the water outlet 3 and the ventilation openings 23 opening therein, which Housing interior of the aerator housing 2 are mixed with the water flowing through to form a sparkling-soft outlet jet.
  • the water flowing through is guided downstream of the jet splitter 22 in the housing interior of the jet regulator housing 2 along webs 24, 25, which protrude on both sides over a housing wall 28 arranged in the longitudinal center plane of the housing and extend transversely to the direction of flow in the jet regulator housing 2.
  • These webs 24, 25 are provided in offset rows of webs, the webs 25 provided in the downstream row of webs having an elongated web cross-section in the direction of flow, while the web cross-section of the webs 24 arranged in the inflow-side rows of webs is circular.
  • the webs 24, 25 arranged in the rows of webs form a jet regulating device, which decelerates the individual jets coming from the jet splitter 22 and the ambient air with tearing, additionally splits them up and mixes them with the ambient air.
  • the water mixed with the ambient air in this way is formed into a flat, ribbon-shaped outlet jet by the grid structure 5 provided on the outlet-side end face of the jet regulator housing 2 . So that this jet pattern is not affected by unwanted Leakage flows is impaired, a circumferential annular groove 26 is provided on the outer circumference of the jet regulator housing 2, in which annular groove 26 a circumferential ring seal 27 is arranged.
