Definitions

  • the seal between the shower base and the bell-shaped housing is made using O-ring seals, which are manufactured and assembled as separate parts. Costs arise from the manufacture, storage and assembly of these separate seals.
  • the object of the present invention is to design a shower head of the type mentioned at the outset that the costs associated with the seals which are required for sealing the shower base against the rest of the shower head are kept as low as possible.
  • the seals with which the shower base is sealed off from the rest of the shower head are not separate (supplier) parts which are manufactured independently of the manufacture of the shower base, kept in stock and then inserted between the shower base and the housing during the final assembly of the shower head .
  • the seals in the manufacture of the shower base are made with almost no cost, although they are already in their final place of use and therefore no longer require separate storage and assembly. In this way, many handling steps that were still required in the prior art in connection with these seals are eliminated.
  • the embodiment of the invention in which the seals are connected in one piece to the nozzle inserts is particularly favorable.
  • the one-piece connection is established in that at least one seal is connected to at least one nozzle insert via at least one material vane that extends along the inner surface of the perforated plate.
  • the material vane can be arranged in a groove formed in the inner surface of the perforated plate.
  • the nozzle inserts are formed in one piece with a shock protection plate which essentially covers the entire outer surface of the perforated plate and is made of the same material as the nozzle inserts.
  • this shock protection plate forms a shock protection for the outer surface of the perforated plate, which itself is made of rigid material and not itself is so shock resistant.
  • This shock protection plate can also be realized without significant additional costs due to the joint production with the nozzle inserts.
  • an embodiment of the invention is also advantageous in that the seal is connected to the shock protection plate via at least one material lug which extends through a hole in the perforated plate.
  • the impact protection plate which is arranged on the side of the perforated plate opposite the seal, can practically always be reached in a short way through the connecting hole in the perforated plate, regardless of the respective position of the seal.
  • shower bases are provided with a circular circumference, which is why the seal between the shower base and the rest of the shower head is generally designed as an annular seal.
  • This plurality of material flags ensures a good flow of material when spraying the nozzle inserts, the shock protection plate and the seals. They also ensure good cohesion of the various components of the shower base, including the seal (s), even if the soft-elastic material is not molded onto the rigid perforated plate in two components, that is why it is already attached to the rigid perforated plate for this reason.
  • the shower head shown comprises in a manner known per se a bell-shaped housing 2, the open, lower end of which is closed by a multi-part shower base 1.
  • the shower base 1 is detachably fastened by means of a central screw 3 to the internals of the shower head accommodated within the housing 2 in a manner not of interest here.
  • the shower base 1 in turn comprises a perforated plate 1 a made of a relatively rigid plastic material, which is covered on the outer surface, that is to say on the surface facing downwards in the drawing, with a shock protection plate 1 b made of relatively soft, elastic material.
  • the impact protection plate 1b like all those components to be described, which consist of the same relatively soft, elastic plastic material, can be injection molded onto the perforated plate 1a using two-component technology.
  • the impact protection plate 1b essentially covers the entire outer surface of the perforated plate 1a.
  • the perforated plate 1 a of the shower base 1 has, in a manner known per se, a plurality of sets of through openings 4, 5 which are arranged on concentric circles around the central axis of the shower base 1 at regular angular intervals.
  • the exact hole pattern which is formed by the through openings 4, 5 of the perforated plate 1a is without in the present context Matter.
  • the through holes 5 of the perforated plate 1 a which are somewhat larger in diameter, are each penetrated by a hose-like nozzle insert 6 which has a relatively small axial length, that is to say only slightly protrudes the perforated plate 1 a on the upper side (facing the interior of the housing 2 of the shower head).
  • the hose-like nozzle inserts 6 are each axially penetrated by a nozzle channel 7 of relatively large cross-section, which tapers conically towards the outside in the illustrated embodiment.
  • the hose-like nozzle inserts 6 are also integrally formed on the impact protection plate 1b and are made of the same material as this.
  • the passage openings 4 of the perforated plate 1a are each penetrated by hose-like nozzle inserts 8, which are integral with the impact protection plate 1b, but which have a greater axial length than the nozzle inserts 6, that is to say they protrude further on the inside of the perforated plate 1a.
  • the hose-like nozzle inserts 8 are likewise each traversed by nozzle channels 9, which have a small cross section in comparison to the nozzle channels 7 of the nozzle inserts 6.
  • the nozzle channels 9 also taper from the inside to the outside.
  • the nozzle inserts 6 have a special shape, which there facilitates mechanical flexing by the user's sweeping hand in order to blow off limescale deposits in the nozzle channels 9, in particular in the vicinity of the water outlet openings 11. This shape is of minor importance in the present context and is therefore not described in detail.
  • the axially shorter hose-like nozzle inserts 6 protrude into a first water space 13 formed inside the housing 2.
  • the axially inner ends of the axially longer hose-like nozzle inserts 8, on the other hand, become received in through holes 14 of an inner partition 15, which is part of an insert 20 and separates the first water space 13 within the housing 2 from a second water space 16, which is at a greater distance from the shower base 1.
  • the insert 20 also has a central bore 21 which runs coaxially to the central fastening screw 3 in the direction of the shower base 1.
  • the central bore 21 is extended by an extension 22, which is delimited by an annular collar 23 on its circular outer circumference.
  • the collar 23 lies with its annular end face on the top of the perforated plate 1a.
  • an annular seal 25 is accommodated, which prevents the passage of air and / or water through the gap between the collar 23 and the perforated plate 1a.
  • the groove 24 in the perforated plate 1a is connected to the outer surface of the perforated plate 1a via a plurality of axially parallel bores of relatively small diameter distributed over the circumference.
  • the ring seal 25 is made of the same material as the shock protection plate 1b and the nozzle inserts 6 and 8. It is connected in one piece to the shock protection plate 1b via the holes 26 of the perforated plate 1a through material flags 33.
  • the Perforated plate 1 a On a circle with a radius that is smaller than the radius of the collar 23 on the insert 20 is the Perforated plate 1 a is provided with a plurality of through bores 27 distributed over the circumference, which continue axially in corresponding through bores 28 of shock protection plate 1 b. Only one of these through holes 27 and 28 can be seen in the drawing.
  • a second annular seal 29, which is also made of the same material as the shock protection plate 1b and the nozzle inserts 6 and 8, lies in a step 30 which is formed on the inside of the perforated plate 1a in its radially outermost region.
  • the ring seal 29 is connected in one piece to the adjacent nozzle inserts 6 and 8 via a plurality of material lugs 31 distributed over the circumference of the shower base.
  • the ring seal 29 seals three parts against one another: the perforated plate 1a, the insert 20 and the housing 2 of the shower head.
  • the water flowing in in a known manner through the handle 2 a of the shower head is directed to the first water space 13 or to the second water space 16 by means of a changeover device which is operated via a rocker-shaped actuating member 17.
  • the changeover device If the changeover device is such that the water reaches the first water space 13, it can exit from there via the nozzle channels 7 of the tubular nozzle inserts 6 and their outlet openings 10. Due to the relatively large diameter of the outlet openings 10, relatively slow water jets with a large diameter result, which are known as "soft jets". These water jets are also mixed with air in a manner not of interest here, which is sucked in through the through bores 27, 28 of the shower base 1 and the central bore 21 of the insert 20.
  • the switching device is actuated by means of the rocker-shaped actuating member 17 in such a way that the water flowing in via the handle 2a reaches the second water space 16, then this water flows through the openings 14 in the partition 15 into the hose-like nozzle inserts 8 of the shower base 1.
  • the water is greatly accelerated; it emerges from the openings 11 at high speed in the form of a relatively narrow jet.
  • These water jets are therefore also called "hard jets”.
