Description

The invention relates to a shower head, in particular for a hand shower, with

  • a) an essentially bell-shaped housing in which at least one water space which can be connected to a water inlet channel is formed;
  • b) a shower base which closes off the bell-shaped housing and comprises:
  • ba) a perforated plate made of rigid material, which has a plurality of through holes;
  • bb) a multiplicity of hose-like nozzle inserts, which consist of relatively soft, elastic material, are each penetrated by a nozzle channel ending in a water outlet opening and are each passed through a through hole in the perforated plate,
  • c) a seal which seals the shower base against the housing or an insert arranged in the housing, which together with the nozzle inserts is made of the same material as this and is integral with the nozzle inserts, or
    a plurality of seals which seal the shower base against the housing and an insert arranged in the housing or a plurality of inserts arranged in the housing, which are made together with the nozzle inserts from the same material as these and are integrally connected to the nozzle inserts.
  • It is known that the water outlet openings Shower floors tend to last over the course of their useful life to calcify the shower head. This is expressed first in a spray pattern, the geometry of which is new deviates, as well as a lower output of liters. The lime deposits can progress so far that finally the water outlet openings completely are clogged.

    For this reason it is e.g. B. from DE-GM 90 17 978 or the DE-GM 93 03 986 known, the water outlet openings on hose-like nozzle inserts made of soft elastic Train material. This can be done by manual sweeping can be mechanically tumbled, that on the lateral surfaces of the nozzle channels, in particular in the area of the water outlet openings Lime layers are blasted off. The water flow through the water outlet openings in the shower base is then free again.

    The seal between the shower base and the bell-shaped In these cases, the housing is made using O-ring seals, which are manufactured as separate parts and to be assembled. Both through the manufacture as well the storage and assembly of these separate Seals incur costs.

    From US-PS 24 02 741 is a shower head of the beginning known type known. With this are all nozzle inserts summarized in one piece on a plate that adapts to extends along the inside of the rigid perforated plate. This plate connecting the nozzle inserts is on their Provide the outer circumference with a sealing lip, which the Sealing between the shower base and the housing is used. So this is about an already existing part, namely the one connecting the nozzle inserts Plate to be used simultaneously as a seal. About seals, which are not in close proximity to the nozzle inserts and with them in no functional There is nothing in this publication testified.

    The object of the present invention is a shower head of the type mentioned in such a way that it can be manufactured cheaper overall.

    This object is achieved in a shower head of the type mentioned in that

  • d) at least one seal is connected to at least one nozzle insert via at least one material vane.
  • According to the one-piece relationship between the nozzle inserts and the seals removed from them produced by a separate material flag. The material flag can be in one in the inner surface the perforated plate formed groove.

    In a very advantageous embodiment of the invention the nozzle inserts are in one piece with a shock protection plate trained that essentially the whole Covering the outer surface of the perforated plate and from the same Material like the nozzle inserts. This bumper plate forms, as the name already expresses, a shock protection of the outer surface of the perforated plate, the yes itself consists of rigid material and not itself is so shock resistant. This shock protection plate also leaves due to the joint production with the nozzle inserts Realize without any significant additional costs.

    If such a shock protection plate is used, then also an embodiment of the invention in the manner of Advantage that the seal has at least one material lug, through a hole in the perforated plate extends through, connected to the shock protection plate is. The shock protection plate, which is on the seal opposite side of the perforated plate is arranged, can be practically independent of the respective position the seal through the connecting hole in the Always reach the perforated plate in a short way.

    Generally, shower trays are circular in circumference provided, which is why the seal between the shower base and remaining shower head generally as a ring seal is trained. Recommended in these cases there are several material flags over the circumference the seal are provided distributed. This majority of material flags provides a good material flow when Spraying the nozzle inserts, the shock protection plate and of the seals safely. They also take care of you good cohesion of the different components of the Shower base including the seal (s), even if the soft elastic material is not in two component technology is already molded onto the rigid perforated plate for this reason fixed on the rigid perforated plate is.

    Of course, the spraying is independent of this all soft elastic components to the rigid Perforated plate in the well-known two-component technology in Possible and advantageous within the scope of the invention.

    An embodiment of the invention is as follows explained in more detail with reference to the drawing; the only figure shows the (partial) side view of a shower head, partially on average.

    The shower head shown includes in and of itself known a bell-shaped housing 2, the open, lower end through a multi-part shower base 1 is complete. The shower base 1 is by means of a central screw 3 to the inside of the housing 2 not installed fittings of the shower head in here detachably attached in more interesting manner.

    The shower base 1 in turn comprises a perforated plate 1a made of relatively rigid plastic material that the outer surface, i.e. on the bottom in the drawing facing surface, with a shock protection plate 1b relatively soft, elastic material covered is. The shock protection plate 1b can do just like all those components to be described, which are made from the same relatively soft, elastic plastic material consist of two-component technology on the perforated plate 1a are injected. The impact protection plate 1b covers essentially the entire outer surface of the perforated plate 1a.

    The perforated plate 1 a of the shower base 1 shows in and in a manner known per se, several sets of through openings 4, 5 on concentric circles around the Center axis of the shower base 1 around in regular Angular distances are arranged. The exact hole pattern, which of the through openings 4, 5 of the perforated plate 1a is formed is without in the present context Concern.

    The through holes slightly larger in diameter 5 of the perforated plate 1a are each of a hose-like Nozzle insert 6 penetrates a relatively has a small axial length, that is, the perforated plate 1a the upper one (to the inside of the housing 2 of the shower head facing) only slightly overhanging. The tubular ones Nozzle inserts 6 are each from a nozzle channel 7 axially penetrates a relatively large cross section, which is in the illustrated embodiment to the outside tapered towards. The hose-like nozzle inserts 6 are also in one piece on the shock protection plate 1b molded and consist of the same material as this.

    The through openings 4 of the perforated plate 1a are also each penetrated by hose-like nozzle inserts 8, which are in one piece with the impact protection plate 1b, but which have a greater axial length than the nozzle inserts 6, so continue to protrude on the inside of the perforated plate 1a. The tubular nozzle inserts 8 are also each crossed by nozzle channels 9, the comparison a small one to the nozzle channels 7 of the nozzle inserts 6 Have cross-section. The nozzle channels 9 also taper each inside out.

    At the outer end, the nozzle inserts 6 have a special one Shaping, which there is a mechanical flexing relieves the user's hand, to limescale deposits in the nozzle channels 9, in particular to blow off near the water outlet openings 11. This shape is in the present context of subordinate meaning and is therefore not closer described.

    If the shower base 1, as shown in the drawing, is mounted on the housing 2 of the shower head, protrude axially shorter hose-like nozzle inserts 6 in one first water space formed within the housing 2 13. The axially inner ends of the axially longer ones hose-like nozzle inserts 8, however, are in through holes 14 an inner partition 15 is added, which is part of an insert 20 and the first water space 13 within the housing 2 from a second water space 16 separates a greater distance from the shower base 1 has.

    The insert 20 also has a central bore 21, the coaxial to the central mounting screw 3 in Towards shower floor 1. Nearby of the shower base 1 is the central bore 21 through a Extension 22 extends at its circular The outer circumference is limited by an annular collar 23. The collar 23 lies with its annular end face at the top of the perforated plate 1a. In a groove 24 at the top of the perforated plate 1a is an annular seal 25 housed which the passage of air and / or Water through the gap between collar 23 and perforated plate 1a prevented. The groove 24 in the perforated plate 1a protrudes several axially parallel holes distributed over the circumference relatively small diameter with the outer surface the perforated plate 1a in connection. The ring seal 25 consists of the same material as the shock protection plate 1b and the nozzle inserts 6 and 8. It stands with the Shock protection plate 1b through the holes 26 of the perforated plate 1a penetrating material flags 33 in one piece.

    On a circle with a radius smaller than that Radius of the collar 23 at the insert 20 is the Perforated plate 1a with several distributed over the circumference Through holes 27 provided, which are in corresponding Through holes 28 of the shock protection plate Continue axially. 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 bumper plate 1b and the Nozzle inserts 6 and 8 is made in one Step 30, which on the inside of the perforated plate 1a is formed in the radially outermost region. The Ring seal 29 is several over the circumference of the Material flags 31 distributed along the shower base the neighboring nozzle inserts 6 and 8 in one piece in connection. The ring seal 29 seals three parts against each other: perforated plate 1a, insert 20 as well as the housing 2 of the shower head.

    Because of the one-piece connection of all of the same soft elastic material existing parts, in particular also because of the connection between the ring seals 25, 29 and the nozzle inserts 6, 8 or the impact protection plate 1b it is possible to seal the Shower base 1 required on the rest of the shower head Seals in the manufacture of the shower base 1 even without having to make a special operation and position it in the right place.

    The function of the shower head described is as follows:

    This in a known manner through the handle 2a of the shower head inflowing water is switched off via a rocker-shaped actuator 17 is operated, either to the first water room 13 or passed to the second water space 16.

    Is the changeover device so that the water in the first water chamber 13 arrives, so it can from there the nozzle channels 7 of the tubular nozzle inserts 6 and the outlet openings 10 emerge. Because of the relatively large diameter of the outlet openings 10 there are relatively slow water jets large diameter, known as "soft blasting" are. These water jets are also not in here interestingly mixed with air, which via the through bores 27, 28 of the shower base 1 and the central bore 21 of the insert 20 is sucked in becomes.

    If by means of the rocker-shaped actuator 17 the changeover device is actuated so that the the water flowing into the handle 2a into the second water space 16 arrives, this water flows through the passage openings 14 of the partition 15 in the hose-like Nozzle inserts 8 of the shower base 1 above. In the proportionate narrow nozzle channels 9 of the hose-like nozzle inserts 8, and especially in their conical the outlet opening 11 becomes tapered end regions the water accelerates strongly; it occurs in the form of a relatively narrow beam at high speed out of the openings 11. These water jets will therefore also called "hard blasting".
