Definitions

  • the invention relates to a shower head with a lower annular Base plate from which the water jets emerge, with one above arranged annular jet disc, with one above the jet disc arranged annular nozzle plate and with between base plate and Jet disc and / or arranged between the jet disc and nozzle plate annular sieves, the nozzle plate on its upper side a variety of Forms nozzles into which the water enters and through which the water flows into one of the Nozzle plate formed mixing chamber arrives, and the nozzles of the Nozzle plate with the openings of the spray disc and the base plate so that they are aligned with each other.
  • the object of the invention is a shower head of the type mentioned above to improve the exiting soft rays a high level of homogenization of air and water and with this optimal mixing in their Shape are stable.
  • This object is achieved in that the mixing chamber the nozzle plate through radial vertical webs in individual mixing chambers is divided such that there is a mixing chamber below each nozzle, which is separated from adjacent mixing chambers by the webs.
  • each water jet generated by the nozzle of a nozzle plate passes into its own mixing chamber without being disturbed by neighboring rays to be able to. This leads to a high leveling of the rays and a optimal mixing with air at the bottom of the nozzle plate is sucked in.
  • the construction is of great simplicity.
  • the effect of the nozzles of the nozzle plate can also be increased by if each nozzle in two to four in particular sector-shaped openings is divided. The flow rate of the water in the nozzles is thereby still increased and thus sucked in even more air. It is also an advantage if the mixing chambers are at least partially open to the outside in order to Suck air into the mixing chamber.
  • the spray disc on its top and / or Underside has radial webs between their through openings in order to their top and / or bottom to form mixing chambers with the Mixing chambers of the nozzle plate are aligned. This ensures that the individual water jets coming from the individual mixing chambers again get into individual mixing chambers of the spray disc, so that a further improvement of the mixing of water and air and thus a further optimization of the homogenization is achieved.
  • the shower head works optimally, it is important that the water flow through the nozzles and openings of the individual parts to each other exactly are aligned coaxially. It is proposed that at the bottom of the Nozzle plate are formed on the inside and / or outside projections, which in Recesses of the spray disc, the base plate and / or the sieves form fit. Alternatively, it is suggested that on top The bottom plate is formed on the inside and / or outside projections, which in Recesses in the nozzle plate of the spray disc and / or the screens form fit.
  • a third alternative proposes that the top and / or bottom of the spray disc inside and / or outside Projections are formed in the recesses of the nozzle plate, the Insert the base plate and / or the sieves in a form-fitting manner. Through this in The individual parts can protrude from each other be precisely aligned before they are installed in the underside of the shower head become.
  • a pre-assembled, securely holding assembly is achieved when the Snap projections into or behind the recesses.
  • the shower head 1 has an outer rotationally symmetrical housing 2, whose top has a water connection 3 with which the shower head for Example can be attached to the handle of a hand shower.
  • the shower head can but can also be used in other areas.
  • this forms a coaxial middle Region 4 that can form a turbine for a pulsating jet.
  • this area can also be closed or other types of Form water jets.
  • the middle region 4 is surrounded on the outside by an annular region 5 which is composed of the following parts, which are all arranged coaxially:
  • a base plate 6 At the bottom is a base plate 6 with a multitude of cylindrical ones axially parallel passage openings 7, each of which is mixed with air Water jet emerges.
  • An annular flat sieve lies above the base plate 6 8 and above a jet disc 9.
  • the nozzle plate 11 forms on its top an annular plate 12, the The top and bottom are at right angles to the axis of the shower head.
  • nozzles 13 which in Embodiment each consisting of four sector-shaped openings 14 are composed.
  • the water flows through the openings 14 from above below to get into a mixing chamber 15 of the nozzle plate 11.
  • the nozzle plate is designed in the shape of an inverted "U's" 11 forms a separate mixing chamber on its underside for each nozzle 13, formed by a vertical radial web 16 between two nozzles is.
  • the nozzle plate 11 forms on its underside 14 Mixing chambers 15 corresponding to the fourteen nozzles 13.
  • the outer leg of the cross-sectionally U-shaped underside of the Nozzle plate 11 is made shorter than the inner one, so that the Nozzle plate on the outside forms an annular feed opening 17 through which the water jet flowing through the nozzle plate sucks air laterally.
  • the base plate 6 With the housing wall a gap-shaped Space 18 through which air can be sucked in from below.
  • the jet disc 9 In the same way as with the nozzle plate 11 by vertical radial webs 16 individual mixing chambers are formed for each water jet and each nozzle, the jet disc 9 also has individual radial webs 9a on the underside between their passage openings 19, so that the jet disc 9 for a mixing chamber 9b is provided for each jet and each opening.
  • the jet emerging from the jet disc 9 arrives after passing through the Siebes 8 in the passage opening 7 of the base plate 6, the upper edge of the Passage opening 7 has a chamfer 20 to ensure optimal entry and to create good beam shaping.
  • the passage openings 7 of the Bottom plate 6 thus form the well-mixed jet around it afterwards to let out.
  • the openings or nozzles 13 of the nozzle plate 11, the openings 19 of the Jet disc 9 and the passage openings 7 of the base plate 6 are in these Parts are available in the same number and are aligned one above the other, the mixing chambers are also aligned with one another, so that an optimal Forming and mixing of each individual jet is guaranteed.
  • the nozzle plate 11 On the inside of the nozzle plate 11 there are projections formed on the underside 21 in front, which in correspondingly shaped recesses 22 of the other parts 8 to 11 in order to align the parts exactly to each other.
  • This snaps nose or pin-shaped projection in each case in the recess or behind the Recess of the bottom plate 6, so that all parts one after snapping Form the pre-assembled module before it is inserted into the shower head.
  • the Projections 21 can additionally or alternatively also on the outside and additionally or alternatively on the base plate 6 or on the radiant panel 9 be molded to in corresponding recesses 22 of the other parts in particular to engage.
