Definitions

  • the invention relates to a shower head, comprising a shower head with an inlet and an outlet, a shower base releasably attached to the shower body and closing the outlet, and a rubber-elastic nozzle plate resting on a fixed support plate of the shower base with a plurality of molded-on elastic nozzle projections which engage in corresponding receiving bores Intervene support plate, have a greater axial length than the associated receiving bores of the support plate and protrude beyond the outer surface of the support plate even when not subjected to liquid pressure with elastically deformable ends.
  • a self-cleaning effect is to be achieved for the nozzle projections referred to there as tubes.
  • the nozzle projections are designed as relatively thin-walled tubes, the downstream part of which collapses or collapses in the depressurized state and closes the respective jet outlet opening.
  • the passage openings should be largely sealed off from the atmosphere, so that the water present in the shower head cannot dry out with the formation of limescale deposits.
  • the thin-walled tubes are to be elastically widened, so that any possible incrustation flakes off at the initial stage and should be flushed out with the shower water.
  • this known shower head may have the desired self-cleaning effect
  • the use of thin-walled tubular nozzle projections is disadvantageous for the spray pattern generated with the shower head.
  • the thin-walled nozzle projections experience different elastic expansions depending on the water pressure. At low pressures, the emerging jet is restricted by the thin-walled nozzle projections, while at higher pressures the expansion of the nozzle projections can go so far that the water jet is no longer adequately guided through the nozzle projections. It is therefore obvious that ange sight that usually within acceptable limits such as 0.5 and 5 bar changing water pressures, an acceptable spray pattern cannot be achieved with this known shower head.
  • the liquid fluid in the nozzle projections is automatically and elastically adapted to the dimensions of the liquid channels in order to ensure that even with small ones Liquid pressures the emerging jet remains spread out and the individual streams do not unite into a single coarse jet shortly after exiting the shower head.
  • the elastically expanding or contracting liquid channels in the nozzle projections are also intended to achieve a self-cleaning effect for the shower head, so that solids are discharged and limescale deposits are broken up and rinsed out through the nozzle openings.
  • the self-cleaning effect of this known shower head is not sufficient, in particular in the case of hard to very hard tap water, in order to remove the rapidly and massively forming limescale deposits or to reduce the extent to which the jet formation does not interfere.
  • the deposits which form directly on the outside of the nozzle openings are not or only inadequately removed by the self-cleaning action of the known shower head.
  • the invention has for its object to provide an improved shower head, in which the nozzle projections at the usual water pressures do not experience any deformation impairing the spray pattern and in which a complete, but at least extensive removal of the outer scale deposits at the nozzle openings is still possible.
  • the task is solved based on the type of shower head specified at the outset in that the nozzle projections are thick-walled at their jet-forming outlet ends and are dimensionally stable against water pressures of up to 5 bar, but are deformable from the outside by mechanical action, with the nozzle projections at the outlet end from the
  • the cross-sectional area formed outside diameter is 7 to 10 times as large as the exit cross-sectional area formed from the clear width of the jet outlet opening, that the nozzle plate with the integrally molded nozzle projections is formed from a rubber-elastic material with a Shore hardness of 40 to 50 and that the elastically deformable ends of the nozzle protrusions protrude by 1 to 2 times the outer diameter of the nozzle protrusions over the outer surface of the support plate.
  • the nozzle projections are not widened by the water pressure on the one hand because of their thick walls and the specified material selection at their jet-forming outlet ends, so that they deliver a well-guided water jet with a defined jet pattern under all operating conditions.
  • the nozzle projections always protrude beyond the outer surface of the support plate of the shower base so that the protruding ends, even when the shower head is not used, ie when the shower head does not have water flowing through it For example, they are exposed to the hand or fingers of the user and can be compressed and / or bent by elastic deformation by hand, while opposing the mechanical external deformation action due to their design and their material with an eraser-like resistance.
  • the nozzle plate can be easily made from a suitable, relatively soft rubber material. Correspondingly soft elastomeric plastics are also suitable.
  • the liquid channels in the nozzle projections are advantageously designed as stepped bores, with a larger inlet cross section and a smaller outlet cross section. If the axial length range of the larger inlet cross-section of the liquid channels protrudes beyond the outer surface of the support plate, the elastic deformability of the ends of the nozzle projections projecting beyond the outer surface of the support plate is further increased, which further removes any deposits from the liquid channels and / or at the outlet openings facilitated.
  • the nozzle projections are appropriately rounded at their ends.
  • the support plate can be flat and provided with receiving bores aligned parallel to one another.
  • the support plate is preferably curved outwards at least on its support surface for the rubber-elastic nozzle plate, the receiving bores being arranged to diverge from one another in the flow direction starting from the support surface.
  • the nozzle plate is clamped at its peripheral edge between an annular surface of the shower body and the support plate with the shower base attached to the shower body.
  • a pressure ring is inserted between the annular surfaces of the shower body and the peripheral edge of the nozzle plate. If the shower base is screwed to the shower body using a circumferential thread engagement, the pressure ring ensures that the circumferential edge of the rubber-elastic nozzle plate is not carried along in the circumferential direction by friction, as a result of which shear stresses on the nozzle projections engaging in the receiving bores of the support plate are avoided.
  • the shower head can also be designed in such a way that it does not generate a geometrically defined spray pattern, but rather that the spray pattern can be adjusted for different propagation.
  • the support plate of the shower base is designed to be elastically deflectable and engages with a threaded part concentrically attached to it with a complementary threaded part attached to the shower body to achieve different curvatures of the support plate.
  • the curvature of the support plate is more or less large, corresponding to a larger or smaller beam spread.
  • the simple shower head shown in FIG. 1 in a first embodiment is essentially composed of a shower body 1 with inlet 2 and outlet 3 and a shower base 4.
  • the shower base 4 has a cylindrical peripheral edge 5 with an internal thread, with which it is screwed onto a cylindrical ring projection 6 of the shower body 1 provided with a corresponding external thread.
  • the annular projection 6 surrounds the outlet 3 of the shower body 1.
  • the inlet 2 is located in a lateral projection 7 of the shower body 1, which is intended for connecting a feed line (not shown) and possibly a handle (not shown) which communicates with the inlet 2 .
  • a fixed support plate 8 closing the outlet 3 is connected in one piece.
  • the support plate 8 is curved in the example shown for beam expansion outwards and has two concentric circular rows of receiving bores 9, which are arranged slightly diverging from each other according to the curvature of the support plate 8 in the flow direction.
  • the receiving bores 9 can also be arranged in a different geometric configuration depending on the desired properties of the shower jet.
  • the central area of the support plate 8 is shown as a closed wall.
  • receiving bores can also be provided in this area.
  • the support plate 8 is overall with provided with a curvature. For the intended purpose of expanding the jet, it would, however, be sufficient if only its inner surface, which serves as a support surface 10 for the nozzle plate 11, which will be described in more detail below, has a curvature.
  • the nozzle plate 11 made of a relatively soft rubber or a corresponding elastomeric plastic has a number of molded-on elastic nozzle projections 12 corresponding to the number of receiving bores 9 in the support plate 8, the mutual distances and the diameter of which are dimensioned such that the nozzle projections 12 into the assigned receiving holes 9 can be inserted.
  • the nozzle plate 11 can be manufactured as a flat component because, due to its material elasticity, it can easily adapt to the curvature of the support plate 8.
  • the liquid channels 13 in the nozzle projections 12, the orientation of which is predetermined by the axial direction of the receiving bores 9 when the nozzle plate 11 is attached to the support plate 8, are designed as simple stepped bores in the example shown, the larger diameter area of the stepped bore facing the interior of the shower body 1 is, while the smaller diameter areas of the stepped bore form the nozzle outlet cross-section.
  • the axial length of the elastic nozzle projections 12 is substantially greater than that of the associated receiving bores 9, as a result of which the nozzle projections 12 with their outer ends protrude clearly beyond the outer surface 14 of the support plate 8.
  • the outer ends of the nozzle projections 12 can therefore be easily deformed elastically by a slight external force, which means that they can be easily freed of any scale deposits. For this it may be sufficient if the shower head with the outer surface 14 is pulled past a suitable edge of the shower device, the outer ends of the nozzle projections are successively deformed and elastically returned to their starting position. It is therefore not absolutely necessary to deform the nozzle projections directly by hand or fingers.
  • the nozzle plate 11 is firmly clamped with its peripheral edge between the ring surface 15 of the ring projection 6 and the support plate 8, the clamping resulting when the shower base 4 is screwed onto the shower body 1.
  • a pressure ring 16 is inserted between the ring surface 15 and the nozzle plate 11, with the aid of which it is prevented that relative movements between the ring projection 6 and the support plate 8 are transmitted to the elastic nozzle plate 11 during screwing movements of the shower base 4.
  • the pressure ring 16 rests on the nozzle plate 11 and takes part in the screwing movements of the shower base 4, whereby it slides on the ring surface 15 when it reaches it when screwing it on, or when it separates from it when unscrewing it.
  • the nozzle plate 11 is provided on its peripheral edge with an annular rib 17 which engages in a corresponding annular groove 18 in the support plate 8. This engagement ensures that the nozzle plate 11 is also positively connected in its edge region to the support plate 8, this form fit not being lost even when the peripheral edge of the nozzle plate 11 is clamped in.
  • a shower head in which the angle of propagation of the emerging shower jet can be set within certain limits.
  • a corresponding cylindrical projection 20 of a cup-shaped housing part 21 is inserted in a cylindrical opening 19 of the shower body 1 'in a sealed manner by means of an O-ring seal 22.
  • the cylinder projection 20 is the End face of an inner and cylindrical fastening projection 23 of the shower body 1 'arranged coaxially to the housing part 21.
  • the fastening projection 23 is provided with a central threaded bore 24, into which a stepped bolt 26 with a threaded pin 25 for fastening the housing part 21 to the shower body 1 'is screwed.
  • the stepped bolt 26 is passed through a correspondingly stepped inner bore 27 of the housing part 21 and, with an annular surface 28, rests against an annular projection 29 of the housing part 21 protruding radially inward from the inner bore 27.
  • the fastening projection 23 is arranged such that it does not hinder the flow through the shower head emanating from the inlet 2 '.
  • the inlet 2 ' communicates with an annular interior 30 of the housing part 21 via a plurality of flow channels 31.
  • An annular wall 32 which delimits the interior 30 and which corresponds in function to the annular projection 6 of the first embodiment described with reference to FIG. 1 an external thread onto which the peripheral edge 5 'of the shower base 4' provided with a corresponding internal thread is screwed.
  • the ring wall 32 defines at its downwardly open end the outlet 3 'of the shower body 1' supplemented by the housing part 21. The sealing between the ring wall 32 and the peripheral edge 5 'of the shower base 4' takes over a further O-ring seal 33.
  • the support plate 8 ' which in this second embodiment is also integrally connected to the peripheral edge 5', is designed such that it can be bent more or less elastically in the axial direction.
  • an inwardly coaxially projecting threaded projection 34 is non-rotatably fastened in its center and is screwed into a corresponding threaded hole 35 of the stepped bolt 26.
  • the shower base 4 'and the housing part 21 are rotated together, depending on the direction of rotation of the threaded projection 34 being further screwed into or unscrewed from the threaded bore 35 of the stepped bolt 26 firmly screwed to the shower head 1'.
  • suitable additional constructive measures can be taken to prevent a relative screwing movement between the ring wall 32 and the peripheral edge 5 'of the shower base 4' from occurring during the screwing movement.
  • a nozzle plate 11 ' is provided with molded-on elastic nozzle projections 12', which is provided with a central through-opening 36 for the passage of the threaded projection 34 and which closely rests on the bearing surface 10 'of the support plate 8'. Due to its elasticity, the nozzle plate 11 'adapts to the different curvatures of the support plate 8'.
  • the nozzle projections 12 ' have a substantially greater axial length than that of the receiving bores 9' provided in the support plate 8 '.
  • the ends of the nozzle projections 12 ′ which in this case are also slightly elastically deformable due to the slight external force, are rounded in a cap-like manner, as is already shown in FIGS. 1 and 2 relating to the first embodiment.
  • the liquid channels 13 ' are stepped within the nozzle projections 12', the smallest opening cross section being provided at the outlet opening.
  • additional constructive measures can be taken on the shower base 4 'which prevent water from escaping past the nozzle plate 11' directly through the receiving bores 9 'along the outside of the nozzle projections 12 from the shower head.
  • the individual nozzle projection 12 (12 ') shown in FIGS. 4 and 5 essentially corresponds to the second embodiment according to FIG. 3, but the nozzle projections can also 12 of the first embodiment can be designed as shown in FIGS. 4 and 5.
  • the elastically deformable end of the nozzle projection 12 (12 ') projects in the example shown by approximately twice the outer diameter of the cylindrical nozzle projection over the outer surface 14 (14') of the support plate 8 (8 '), ie with an outer diameter of approximately 3 mm by about 6 mm.
  • the stepped liquid channel 13 (13 ') is composed of an axial length region 37 of larger cross section and an axial length region 38 of smaller cross section, the latter forming the jet-shaping outlet cross section. In the example shown, this has a square cross section, as illustrated in FIG. 5.
  • the cap-shaped rounding of the end of the nozzle projection 12 (12 ') has approximately the shape of a spherical cap.
  • the cross-sectional area of the nozzle projections formed from the outer diameter was approximately 12.5 mm2, i.e. approximately 8, with an outlet cross-sectional area of approximately 1.44 mm2 , Was 7 times as large as the outlet cross-sectional area.
  • the input cross-sectional area of the liquid channels was in each case approximately 3.14 mm2, i.e. the cross-sectional area of approximately 12.5 mm 2 formed from the outer diameter was approximately 4 times as large as the input cross-sectional area.
