Definitions

  • the invention relates to a shower head as part of a sanitary fitting consisting of an upper shell and a lower shell with arranged therein through openings for the water to be distributed over the shower head, wherein in the interior of the shower head consisting of a sealing elastomer water guide mat with a connected to a central water inlet arrangement of in the surface formed water channels is inserted, formed in the bottom of the associated passage openings in the lower shell in alignment arranged outflow openings, wherein the cross section of the formed in the water guide mat water channels is designed such that when blocking the water supply to the shower head and thus weg fallendem pressure of nachströmendem Water in the water channels no more flow of water takes place
  • a shower head with the aforementioned features is in the US 2006/0151640 A1 described.
  • a water guide mat arranged with formed in the surface of the water channels, in the bottom of which are aligned aligned with the passage openings formed in the lower shell of the shower head exhaust ports.
  • the water channels formed in the water guide mat have a corresponding circular course, wherein the water supply to the circular water channels via four connected to the central water inlet, radial running and the concentric water channels each intersecting water channels takes place.
  • the water channels in the water guide mat have a relatively low height, should be effected so that the back pressure of the water channels is still stopped after stopping the water supply pending, so that the pending outside of the shower head air the surface tension of the upcoming Water difficult overcome and can not flow into the shower head, which in turn would result in increased leakage of residual water.
  • the invention is therefore based on the object in a shower head with the features mentioned in the tracking of water following the shutdown of the water supply even further.
  • the invention provides in its basic idea that from the central water inlet to each individual outflow opening a single water channel is guided without a connection with leading to other outflow water channels, its under basis of the thus set adhesion between the water and the elastomeric material of the water guide mat fixed cross-section Water does not flow when the water supply to the shower head is blocked.
  • the invention has the advantage that due to the individual, separated from each other by a central water inlet to each outlet opening in the water guide mat run individual water channels on the one hand and the design of the cross section under the basis of each justified by the water between the water and the material of the water guide mat
  • adhesion on the other hand, the total remaining after stopping the water supply to the shower head water quantity is reduced. Since the cross-section of the individual water channels, taking into account the adhesion even with access of air and the associated pressure compensation in the shower head is not allowed to re-flow of water without an acting water pressure, after stopping the water supply is a subsequent outflow of water from the individual water channels prevents the shower head.
  • the small amount of water remaining in the shower head in combination with the respective small cross-section of the water channels formed in the water guide mat also reduces the risk of Legionella formation.
  • the elastomer used for the production of the water guide mat beyond its sealing property and a good adhesion to the water must also be resistant to hot water or hot water and should not allow the deposition of lime.
  • the use of a silicone-like elastomeric material or of silicone itself has proved to be expedient according to embodiments of the invention.
  • individual nozzles which are connected to the outflow openings of the water guide mat and pass through the passage openings formed in the lower shell, are arranged on the water guidance mat. This ensures that the water introduced into the shower head comes into contact exclusively with the water guide mat or with the elastomer material used therefor.
  • the upper shell rests with a flat bearing surface on the water guide mat and sealingly seals the formed in the water guide mat water channels at the open surface;
  • a good seal of the shower head is effected, because only between the surface of the water guide mat and the surface resting thereon of the upper shell is to ensure a sealing effect; a sealing of the water guide mat against the lower shell, however, is not required.
  • no water leakage can take place because the water is trapped in the respective individual from the central water inlet to the outflow extending water channels.
  • upper shell and lower shell are connected to each other by means of several over the surface of the shower head arranged fasteners together, thereby a uniform surface pressure of the flat surface of the upper shell is exerted on the water guide mat, so that the intended sealing effect is ensured.
  • the out FIG. 1 apparent shower head 10 is composed of an upper shell 11, a lower shell 12 and a water guide mat 13 placed therebetween.
  • individual water channels 15 are worked out, which lead from a central water inlet 16 of the water guide mat 13 to the individual formed in the water guide mat 13 discharge openings 14.
  • a grid are distributed uniformly over the surface of the water guide mat 13 through openings 17 formed on the lower shell 12, elevating from their level Einschraubdome 19 is formed so that the water guide mat 13 can be placed with their feedthrough openings 17 on the lower shell 12 and thereby the Einschraubdome 19th the passage openings 17 of the water guide mat 13 pass through.
  • passage openings 18 arranged in alignment with the outflow openings 14 formed in the water guide mat 13 are formed.
  • an inlet nozzle 21 is arranged, to which a water supply port 22 can be attached, so that the water supplied to the shower head 10 into the central water inlet 16 of the water guide mat 13 and from here via the outgoing therefrom individual water channels 15 to the discharge openings 14 flows.
  • FIGS. 2 to 4 are formed on the water guide mat 13 integrally therewith formed in the direction of the lower shell 12 of the water guide mat 13 projecting spouts 23, which are connected to the discharge openings 14 and extend through the formed in the lower shell 12 passage openings 18, so that via the water guide mat thirteenth guided water does not come into contact with the lower shell 12. Furthermore, it can be seen that the outer peripheral edge portions 25 of upper shell 11, lower shell 12 and intermediate water guide mat 13 are each hook-shaped in a form responsive manner, so that thus a circumferential positive locking of upper shell 11, lower shell 12 and water guide mat 13 against each other realized is. It can be seen that fastening screws 24 guided through the screw-in openings 20 of the upper shell 11 are screwed into the screw-in domes 19 of the lower shell 12.
  • FIG. 5 shows closer, with a square configuration of the shower head 10 shown as an exemplary embodiment, the discharge openings 14 are arranged in the water guide mat 13 in a regular cross grid, and it can be seen that each individual water supply channels 15 in front of the central water inlet 16 to the discharge openings 14 and the connected thereto Spouts 23 run.
