Definitions

  • hose-like nozzle attachments are made of an elastomeric material and can be mechanically tumbled by manual painting so that the layers of lime deposited on the lateral surfaces of the nozzle channels, in particular in the area of the water outlet openings, are blasted off. The water flow through the water outlet openings in the shower base is then free again.
  • a shower head of the type mentioned is known from the market.
  • Its shower base is composed of a rigid perforated plate having a multiplicity of through-bores and an elastically flexible nozzle insert having a multiplicity of nozzle attachments. All nozzle attachments are molded onto a base plate of the nozzle insert. This is in the assembled state on the inside of the perforated plate, so that the water pressure presses the nozzle insert against the perforated plate.
  • the nozzle attachments are passed through the through holes of the perforated plate from the inside out, such that the free ends of the nozzle attachments form the water outlet openings.
  • the perforated base of the known shower head is removed from the housing.
  • the nozzle insert can now be removed from the inside of the perforated plate and tumbled by hand or cleaned in any other way. After cleaning, the nozzle insert is reattached in its place on the inner surface of the perforated plate; of the pre-assembled shower base is then reassembled on the shower head housing.
  • this process which must be carried out each time when cleaning the nozzle insert, is relatively complicated.
  • the object of the present invention is to design a shower head of the type mentioned at the outset in such a way that the nozzle insert can be removed and cleaned without problems.
  • the nozzle insert is thus placed on the rigid perforated plate from the outside; the nozzle inserts are passed through the through holes of the perforated plate from the outside in, so that now the water outlet openings are not formed at the free ends of the nozzle attachments which come to lie inside the shower head, but at the end which has grown together with the base plate of the nozzle insert.
  • Special locking means ensure that the nozzle insert does not detach from the rigid perforated plate even under the water pressure prevailing in the interior of the shower head.
  • An additional advantage of the configuration according to the invention is that the outer surface of the shower base is formed by the base plate made of flexible material, ie this base plate protects the entire shower base from damage Protects bumps.
  • annular space is created between the nozzle attachments and the retaining collars, which to a certain extent allows the nozzle attachments to be flexed manually permitted without removing the nozzle insert from the perforated plate.
  • shower heads of the type of interest here are often designed as so-called "multi-function showers". This means that the water generally flowing in via the handle is directed to one of two water spaces formed in the housing by means of a diverter valve.
  • the two water spaces each communicate with a set of outlet openings in the shower base, with suitable geometry of the water outlet openings and / or other treatment of the water, e.g. B. an air enrichment, for a different character of the emerging water jets in the two operating modes is ensured.
  • the multi-function shower head in which so-called “hard jets” emerge at a relatively high speed and a narrow cross-section in one operating mode and so-called “soft jets” in the second operating mode, which are enriched with air and have a relatively large cross-section.
  • that embodiment of the invention is particularly advantageous in which the free annular spaces communicate with one of the water spaces and are also connected to the outer surface of the shower base via openings in the form of ring segments.
  • outlet openings of one type of beam are thus essentially at the same location as the outlet openings of another type of Rays, eg that of hard rays; the "rough" spray pattern of the shower head is therefore the same in both operating modes.
  • the reference numeral 1 denotes a multi-part shower base, which forms the lower end of a bell-shaped housing, not shown, in a conventional manner. It is generally circular and merges with the outer circumference - in one piece or via a detachable connection - into the housing of the shower head.
  • the shower base 1 comprises a perforated plate 1 a made of relatively rigid material, which has several sets of through bores 3 in concentric circles around its central axis, which is no longer shown in the drawing and can be thought of further to the right.
  • the shower base 1 also comprises a nozzle insert, which bears the overall reference number 1b.
  • the nozzle insert 1b consists of an elastomeric, deformable plastic and is detachably attached to the perforated plate 1a in a manner to be described.
  • the nozzle insert 1b comprises a substantially flat base plate 9 which extends along the outer and thus underside of the perforated plate 1a up to the outer edge thereof. In the area of the outer edge, the base plate 9 of the nozzle insert 1b is provided with an annular sealing bead 30 which engages in a complementarily shaped groove 31 on the underside of the perforated plate 1a.
  • hose-like nozzle extensions 10 are injection-molded, concentrically to the sets of through holes 3 in the perforated plate 1a, which extend through the corresponding holes 3 of the perforated plate 1 into the interior of the shower head.
  • the outer diameter of the nozzle lugs 10 corresponds to the diameter of the through holes 3 in the perforated plate 1a.
  • the lateral surfaces of the nozzle lugs 10 are each formed with an annular retaining collar 32, the axial height of which is selected so that the retaining collar 32 lies in the assembled state on the inner surface of the perforated plate 1a or a chamfer 33 provided in the region of the end of the through bores 3 there is coming.
  • the nozzle attachments 10 are each axially penetrated by nozzle channels 13, which taper conically in their outer area, in such a way that the water jets flowing through them and emerging from outlet openings 15 experience focusing and acceleration.
  • the function of the shower head described above is as follows: In the operation of the shower head, the nozzle channels passing through the nozzle attachments 10 are filled with water from above suitable, not relevant here. Over time, layers of limescale build up inside the nozzle channels 13, but in particular in the area of the outlet openings 15 with a relatively small cross section, which reduce the open flow cross section and can ultimately lead to a complete blockage of the nozzle channels 13. If such a condition has occurred, the entire nozzle insert 1b can be removed from the perforated plate 1a by axial pull; the chamfers 33 in the upper end region of the through bores 3 of the perforated plate 1a are helpful in this process.
  • the nozzle insert 1b If the nozzle insert 1b is detached from the shower head, it can be tumbled by hand in such a way that the layers deposited on the walls of the nozzle channels 13 are blasted off. In addition, it is of course also possible to clean the nozzle insert 1b with a suitable cleaning device, for example a sponge, or with cleaning agents.
  • a suitable cleaning device for example a sponge, or with cleaning agents.
  • the nozzle attachments 10 of the nozzle insert 1b are reinserted into the corresponding through bores 3 of the perforated plate 1a.
  • the retaining collars 32 on the outer lateral surfaces of the nozzle attachments 10 are compressed through the through holes 3 until they can then spring open again in the region of the chamfers 33.
  • the nozzle insert 1b is now "attached" to the perforated plate 1a.
  • Limescale deposits can be cleaned from the nozzle insert 1b in the shower base described without removing the perforated plate 1a from the shower head.
  • the base plate 9 of the nozzle insert 1b which extends along the entire outer surface of the perforated plate 1a, protects the shower base, especially in the rounded outer area, from damage caused by impacts.
  • FIG. 2 shows a second exemplary embodiment of a shower base in radial section, which is very similar to that explained above with reference to FIG. 1. Corresponding parts are therefore identified by the same reference number plus 100.
  • a perforated plate 101a can again be seen in FIG. 2, which together with a nozzle insert 101b form the shower base 101 of a shower head.
  • the perforated plate 101a contains a plurality of through bores 103 on concentric circles around its central axis.
  • the nozzle insert 101b comprises in one piece a base plate 109 and nozzle extensions 110 molded onto the base plate 109, each of which is axially penetrated by nozzle channels 113.
  • the outer diameter of the nozzle attachments 110 is significantly smaller than the diameter of the assigned through bores 103 of the perforated plate 101a.
  • Additional retaining collars 120 are now integrally formed on the base plate 109 of the nozzle insert 101b.
  • the retaining collars 120 have a retaining collar 132 on their edge pointing upwards, that is to say into the interior of the shower head. This protrudes outward on the inside of the perforated plate 101a and, together with the corresponding retaining collars 132, secures the nozzle insert 101b on the perforated plate 101a on all other nozzle attachments 110.
  • the nozzle insert 101b can thus be mounted on the perforated plate 101a in that the retaining collars 120 through the corresponding through bores 103 of the perforated plate 101a are pushed through, which is possible due to the elasticity of the material of the nozzle insert 101b. As soon as the holding collars 132 have passed through the through bores 103, they spring open and thus form a fixation for the nozzle insert 101b. The insertion of the retaining collars 120 and in particular the retaining collars 132 molded onto them into the through bores 103 of the perforated plate 101a is facilitated by a bevel 122 at the outer end of the through bores 103.
  • the shower head shown in FIG. 2 differs from that shown in FIG. 1 essentially in that an annular space 140 is formed between the nozzle attachments 110 and the retaining collars 120. Because of this annular space 140, it is possible to effect a certain flexing in the region of the water outlet openings 115 without removing the nozzle insert 101b from the perforated plate 101a, by the user pressing the hand (or finger) on the lower (outer) surface of the Brushes along the nozzle insert 101b and deforms the nozzle insert 101b in the region of the water outlet openings 115.
  • the flexing of the nozzle insert 101b that can be achieved in this way can, in many cases, be sufficient to blow off deposited limescale layers from the wall of the nozzle channels 113.
  • the removal of the nozzle insert 101b from the perforated plate 101a, as described above, is therefore only required in the exemplary embodiment of FIG. 2 only exceptionally or at very large time intervals.
  • the shower head shown in FIG. 3 is a variant of the exemplary embodiment in FIG. 2. Parts which correspond to those in FIG. 1 are identified by the same reference number plus 200.
  • annular spaces 140 which surround the nozzle attachments 110 concentrically, only had the function of facilitating the walkability of the nozzle attachments 110, the annular spaces 140 in the exemplary embodiment in FIG. 3 have a further function:
  • the bottom of the annular spaces 240 is connected via openings 250 to the outer surface of the shower base, that is to say the outer surface of the base plate 209.
  • the openings 250 have the form of ring segments which concentrically surround the outlet openings 215.
  • the shower base 201 from FIG. 3 is installed inside the shower head as follows:
  • the free ends of the nozzle attachments 210 pointing upward in FIG. 3 are fastened in a partition of the shower head in such a way that the nozzle channels 213 communicate with a water space which is located on the side of the partition facing away from the shower base 201.
  • the annular spaces 240 are connected to a second water space, which is arranged on the side of the partition facing the shower base 201.
  • the inflowing water is fed to the water space on the is the side of the partition facing away from the shower base 201.
  • the water then flows through the nozzle channels 213 of the nozzle attachments 210 and emerges from the water outlet openings 215 as "hard jets".
  • the water space adjacent to the shower base 201 is connected to the water supply.
  • the water taking this route is e.g. enriched with air, enters the annular spaces 240 and exits from there via the openings 250 as "soft rays".
  • the rough position of the "soft jets" on the shower base 201 remains essentially the same as that of the "hard jets", so that the spray pattern of the shower head is essentially the same in both operating modes.
