Definitions

  • the invention relates to a shower assembly comprising a showerhead housing with a fluid inlet and a distributor plate in the showerhead housing, wherein a plurality of separate fluid guide paths are formed between the showerhead housing and the distributor plate and the distributor plate has passage openings from the fluid guide paths.
  • shower heads of sanitary showers in such a way that they can be used to realize a plurality of different jet exit images or jet exit characteristics of a fluid jet which emerges from one or more jet outlet openings of a jet disk terminating the shower head on the outlet side.
  • different jet patterns for a hard jet, a massage jet and a soft jet can be provided.
  • a plurality of separate fluid guide paths are formed between the showerhead housing and an internally disposed distributor plate, and by means of a switching valve, supplied fluid can be selectively supplied to one or more of these fluid guide paths.
  • fluid guide paths are different groups of jet outlet openings of the jet disk in fluid communication, wherein the fluid passes through passage openings in the distributor plate to a fluid outlet space, which forms one or more separate chambers, and from there via the respectively associated jet outlet openings of the jet disk to the outside.
  • the publication DE 35 09 602 A1 discloses a shower assembly for a hand shower, wherein the hand shower comprises a housing with a handle and a bell-shaped end portion and a first, inner insert and a second, outer insert, which are used in the bell-shaped housing end part.
  • the housing contains only function-specific, independent of the respective shower function channels and also non-specific connection means.
  • the inner insert contains nonspecific connection means complementary to the connection means of the housing, from which only large-area, function-specific channels emanate.
  • On the outside Use are summarized all water-bearing channels narrow cross-section and possibly other parts in need of maintenance. Thus, a whole set of different, easy to maintain hand showers are provided using the same housing in which different inner inserts can be used.
  • For each inner liner there is a mating outer liner, with the outer liner having the associated exit-side jet disk.
  • the invention is based on the technical problem of providing a shower assembly of the type mentioned, with which shower heads of different jet outlet characteristics can be realized very variable and flexible and with relatively little design effort.
  • the shower assembly comprises a plurality of jet discs having on the inside different chamber-forming and / or fluidabsperrende structures and which can be mounted either on the distributor plate of the showerhead housing and each one or have multiple jet outlet openings.
  • This makes it possible, depending on the desired beam outlet characteristic to use a corresponding jet disk and to attach them to the distributor plate, which is located in the showerhead housing.
  • it is thus possible to provide showerheads with different jet outlet characteristics using a single showerhead housing and a single distributor plate simply by selecting the respective associated jetplate and mounting it on the distributor plate.
  • the different jet outlet characteristics depending on the jet disk result from the different inside structures of the jet disks, by means of which a water outlet space between distributor plate and mounted jet disk can be subdivided into one or more fluid-separated chambers and / or one or more of the fluid guide paths can be shut off, e.g. can also be realized by shutting off the relevant passage openings of the distributor plate.
  • a cover plate is provided between the housing and the distributor plate, which together with the distributor plate a cartridge insert forms, which has the fluid guide paths.
  • the cover plate and the distributor plate can be preassembled as a cartridge insert and the cartridge insert can then be mounted in the shower head housing before the jet disk is then mounted on the distributor plate of the cartridge insert.
  • the distributor plate is attached directly to the showerhead housing. In this case, the fluid guide paths are formed between the distributor plate and the showerhead housing.
  • a switching valve for switching between the separate fluid guide paths is provided between the water inlet and the fluid guide paths. This may allow the user to set different jet outlet characteristics for the showerhead with a given, mounted jet disk.
  • the switching valve is at least partially disposed in or on the distributor plate. Thus, the switching valve may be integrated in the distributor plate or in the cartridge insert.
  • the distributor plate has, on its outer side, a partition wall structure which encloses the respective passage openings belonging to one of the fluid guide paths as a group.
  • the chamber-forming structures of the jet disks include an outer wall seal in the edge region of the jet disk and different inner wall seals.
  • the outer wall seal seals the jet disc mounted on the distributor plate to the outside.
  • the inner wall seals serve for the desired division of the fluid outlet space between distributor plate and jet disk into corresponding fluid outlet chambers.
  • one of the jet disks has only the outer wall seal and no inner wall seal. This has the consequence that the fluid over its entire surface can escape from this jet disk wherever there are in this jet outlet openings.
  • the one or more other jet discs each have an inner wall seal and therefore different jet exit characteristics.
  • the chamber-forming structures of at least one jet disc include a flexible non-return valve inner wall seal.
  • this inner wall seal in the manner of a check valve is flexible in only one direction, whereby the two fluid outlet chambers separated from the inner wall seal come into fluid connection with one another.
  • the two chambers thus remain fluidly separated from each other or are brought into fluid communication with each other. This can be used in addition to achieving different beam leakage characteristics.
  • a safety lock is provided with which the respective jet disk can be secured against loosening from the distributor plate. This prevents the jet disc from inadvertently coming off the distributor plate. To change the jet disk, the safety lock can be unlocked.
  • the safety lock comprises a locking pin receptacle on the respective jet disc and a locking pin held on the shower head housing, which can be received dismantling in the locking pin receptacle.
  • shower shown has a showerhead 1, which includes a showerhead housing 2 and a one-piece handle housing 3 with this.
  • the showerhead housing 2 has a pot-like shape and defines a corresponding shower head 4.
  • the hollow handle housing 3 receives a water supply sleeve, which defines a fluid supply channel 5, which opens into a fluid inlet 6 of the showerhead housing 2.
  • the water guide sleeve terminates at its free end with an external thread 7, to which, for example, a fluid supply line, such as a shower hose, can be coupled.
  • a cartridge insert 8 is accommodated, which comprises a distributor plate 8a and a cartridge cover 8b. Between the distributor plate 8a and the cartridge cover 8b, a plurality of separate fluid guide paths 9a, 9b, 9c are formed in the cartridge insert 8.
  • the distributor plate 8a has from its inside main surface perpendicularly projecting partitions 10, which sit in a fluid-tight manner in receptacles of the cartridge cover 8b, which thus acts as a cover plate.
  • a change-over valve 11 is integrated into the cartridge insert 8, through which fluid supplied via the inlet 6 can optionally be fed into the various fluid guide paths 9a, 9b, 9c.
  • the switching valve 11 is of a per se known type with a combined axially and rotatably movable valve disc 12 and an axially movable actuating pin 13 which can be actuated by the user via a arranged on the bottom of the showerhead 1 in the transition region between the shower head 4 and handle 3 pushbutton 14 ,
  • the jet disk 15 has a plurality of beam exit openings 16 distributed over its exit surface.
  • a first part of the jet outlet openings 16 is located in a central region 15a of the jet disk 15, a second part of the jet outlet openings 16 is located in a central annular region 15b of the jet disk 15 radially adjoining the central region 15a and a third, remaining part of the jet outlet openings 16 is located itself in an outer annular region 15c of the jet disk 15.
  • a bayonet connection is used to fasten the jet disk 15 to the cartridge insert 8 or the distributor plate 8a.
  • the jet disk 15 is held on the one hand in its central region and on the other hand in its peripheral region by means of respective bayonet connection elements.
  • To this end protrudes from the inside of the jet disk 15 in its central region from a bayonet retaining pin 17 which is circumferentially provided in the vicinity of its free end portion with a bayonet track 17a.
  • the distributor plate 8a has a centric opening and bayonet noses projecting radially inward into this centric opening 18 on.
  • the jet disk 15 circumferentially distributed to a plurality of, for example, three or four radially outwardly facing bayonet projections 19, with which cooperate in the peripheral region of the distributor plate 8 a correspondingly formed bayonet scenes 20, in the matching angular distance on one of the jet disk 15 side facing the Distributor plate 8a are formed, as more clearly in Fig. 6 to recognize.
  • the combined centric and peripheral fixing of the jet disk 15 to the distributor plate 8a is particularly advantageous when using a relatively large-area jet disk and / or at high fluid pressures.
  • FIG. 4 shows a detail of the cartridge insert 8 with the jet disk 15 mounted on its distributor plate 8a.
  • Fig. 5 shows in longitudinal section the cartridge insert 8 with the distributor plate 8a and the cover plate 8b and the integrated switching valve 11, here without the actuating pin 13 and the push button 14th
  • Fig. 6 shows the cartridge insert 8 from below without the mounted jet disk.
  • passage openings 21 can be seen which are provided for each of the fluid guide paths in the distributor plate 8a, in order to forward the fluid from the respective fluid guide path into the outlet space between distribution plate 8a and jet disk 15.
  • the distributor plate 8a On its outer side facing the mounted jet disk 15, the distributor plate 8a has a dividing wall structure 22, which in the example shown comprises two coaxial annular dividing walls 22a, 22b. These subdivide the outlet side of the distributor plate 8a into a centric zone, a middle annular zone and an outer annular zone corresponding to the corresponding areas 15a, 15b, 15c of the jet disk or their three groups of jet outlet openings.
  • the partition wall structure 22 of the distributor plate 8 a cooperates with a chamber-forming structure 23, which is formed on the facing inside of the jet disk 15.
  • This chamber-forming structure 23 can be realized, for example, by a pad or insert made of elastic sealing material on the inside of the jet disk and forms a jet-disk-specific exit chamber structure 24 from the fluid outlet space between distributor plate 8a and jet disk 15.
  • this exit chamber structure contains three fluid-separated exit chambers the mentioned three jet disk areas, ie the central area 15a, the middle ring area 15b and the outer ring area 15c.
  • the outlet chambers are kept separate from each other by a corresponding inner wall sealing the chamber-forming structure 23 from each other.
  • the chamber-forming structure 23 includes a flexible check valve-inner wall seal in the form of sealing lips or sealing webs 25, which create elastically biased against corresponding portions of the distribution plate-partition wall structure 22.
