Definitions

  • a hand shower with such a shower head element is in the DE 10 2007 002 894 B3 disclosed.
  • a particularly flat design of the shower head is possible.
  • the switching of the water inlet from one sub-chamber to the other is done by turning the shower head element.
  • the only drawback is that the shower head element must be round so that it can be swung back and forth in front of the stationary inlet element.
  • a design of possibly desired design of the shower head element in a non-round shape is not possible.
  • the US 5,690,282 discloses a nozzle assembly.
  • a nozzle head By pivoting a nozzle head with a plurality of jet nozzles different types of jet images can be set, as they are known in the field of garden irrigation technology, where, for example, garden plots of different shapes to be watered specifically.
  • a jet pattern formed by a dot nozzle contour can not even develop at distances of less than one meter, which are regularly given in showers.
  • the user in addition to the pivoting of the button, the user must also actuate an additional valve element arranged therein in order to shut off or open individual jet nozzles. This handling is with one-handed operation and overhead, as regularly usual with shower heads, hardly feasible.
  • the object of the invention is thus to achieve a flat design and an easy-to-use and well-sealable switching of the water inlet into the respective sub-chambers, but also to allow other contours of the shower head element.
  • the hollow chamber with its sub-chambers and their multiple inlet openings is not movable, but arranged in a stationary housing.
  • Water is passed from the outside, for example via the handle of a hand shower, to a likewise stationary arranged on the housing support member.
  • a pivotable distributor element is arranged, whose distributor head sweeps when switching over the convex outwardly curved outer wall of the hollow chamber.
  • the distributor head is formed wider than the inlet region in the side wall with the inlet openings, in all positions in which the outlet opening is positioned in front of one of the inlet openings, the remaining inlet openings can be sealed.
  • the pivotable distributor head preferably extends over a more than twice as large angle as the arcuate region which leads from the left outer inlet opening to the right outer inlet opening.
  • a single sealing element is provided which extends over the entire area to be covered by the distributor head and in which the outlet opening is arranged. When swiveling, the distributor head with its sealing element sweeps over the inlet area.
  • inlet openings to the inlet area individually or as a group of a sealing ring surrounded and the distributor head with a rigid convex front wall, which contains the outlet opening, strokes over the housing side fixedly installed seal.
  • each detent position with a separate sealing element.
  • dummy plugs are inserted from the outside at the distributor head. Only in a central recess, a sealing element is provided, which contains the outlet opening. If, for example, three inlet openings are provided on the hollow chamber, then a total of five sealing elements are arranged on the distributor head, namely the sealing element with the inlet opening in the middle and on both sides thereof two additional sealing blind plugs.
  • the distributor element may be advantageous to form as a module, in which the mutually movable parts are arranged completely functional to each other, so that they are a perfect fit.
  • the module can be locked into a recording frame of a superordinate construction group.
  • the jet-forming parts of the showerhead elements can also be of modular design, so that a hand shower first has only an empty receiving frame, in which then the modules are used, so that a completely closed at the bottom and functional hand shower is formed.
  • the installation and Vorrastanno the manufacturer is facilitated, because depending on the desired comfort and price range of the hand shower can easily more or less complex modules are used in the same outer housing or the user is even given the opportunity by supplying different types of modules, the spray pattern after his To put together wishes.
  • shower head elements that represent the functionally essential assembly of a hand shower. They can be integrated into a housing which i.a. a handle portion, with which the hand shower can be held and through which the water supply from the shower hose to the distributor head takes place.
  • the housing 110 comprises a hollow chamber 111 which is delimited by a side wall 115, which has a small height in relation to its extent in the area equipped with nozzle elements. So it is a flat design allows.
  • the side wall 115 is bent so that it has on its outer surface a concave shape in the manner of a portion of a cylinder jacket.
  • a plurality of inlet openings 112 are provided in the side wall 115. These serve to flow into individual chambers within the hollow chamber 111.
  • the subdivision of the shower head element 100 into individual chambers, which are each equipped in particular at their bottom with different nozzles and thus produce different jet patterns and form different functional zones, is from the above-mentioned prior art Technique known in principle, so that the subdivision into sub-chambers is indicated here only by dashed lines. Also, the contour of the hollow chamber 115 in all areas except in the inlet region 116, designed differently than shown here by way of example.
  • the housing 110 continues outside the hollow chamber 111 and there provides a receptacle 118 for the support member 130, in which the distributor element 120 is guided pivotably.
  • the housing 110 terminates on a flange plate 117.
