Description

  • The The invention relates to a water outlet mouthpiece for a faucet with a switchable jet regulator insert, which has a cleaning jet channel and at least one flow chamber having a plurality of water outlet nozzles, wherein at least an inflow opening of the flow chamber with at least one biased in its closed position valve is controllable, such that the inflowing water, the valve of a predeterminable dynamic pressure of the water can be opened.
  • A water outlet mouthpiece of the aforementioned genus is from the DE 44 36 193 A1 known. Here, the inlet openings of four flow chambers are each closed with a valve in the normal position. In the case of a water supply, the water initially flows exclusively through a cleaning jet channel fixedly arranged in the center of the jet regulator insert. As soon as the amount of water is increased and exceeds a certain value, the valves are automatically opened by the back pressure of the water and water flows in addition to the flow chambers and exits through a plurality of water outlet openings as a widened jet of water from the water outlet nozzle. If the amount of water is reduced again, the valves close automatically one after the other and only the cleaning jet channel is supplied with water. The four valves each have a seal and a valve spring, so that this aerator is structurally very complex, large and also because of the large number of moving parts also very susceptible to wear. In addition, a commercial jet regulator can not be replaced without effort against this large jet regulator. Incidentally, the valve can not be closed from the outside, if it once stuck in its open position.
  • From the DE 23 20 624 C2 Another jet regulator is known, in which alternately two valve seats are shut off by a rotary actuation of the housing, whereby a switch is made between an unvented annular spray jet and a centrally vented within the spray jet aerated water jet. Switching takes place here exclusively manually.
  • task The invention is a water outlet nozzle with a jet regulator insert of the type mentioned above in such a way that the Strahlreglereinsatz an automatic switch between a sharp, bundled Cleaning jet, such as for cleaning a razor is required, and a normal, expanded, in particular ventilated Water jet, a soft jet, with as few components as possible easy and wear-resistant allows. Furthermore should the water outlet mouthpiece and the beam controller use universally without any effort against a standard - water outlet mouthpiece or a standard jet regulator insert exchangeable be.
  • These Task is inventively characterized solved, the valve has an axially displaceable in the water flow direction Valve piston having a valve plate and the cleaning jet channel runs in the hollow valve piston and the valve plate at least one water inlet opening having the cleaning jet channel.
  • According to the invention Magnification of the Back pressure of the water on the valve plate of the entire cleaning jet channel shifted in the water outlet direction and the valve is open, so that in addition to the cleaning jet one composed of several individual beams Soft jet emerges from the water outlet nozzles. The cleaning jet channel So here forms with the valve a unit, so that the constructive Effort and the susceptibility to wear is significantly reduced.
  • at an advantageous embodiment the jet regulator insert is arranged in a standardized screw sleeve. This has the big one Advantage that the inventive water outlet mouthpiece or only the jet regulator universal without any effort against a Water outlet mouthpiece with a standard jet regulator or a standard jet regulator is interchangeable.
  • Conveniently, The valve piston may be in the middle of the substantially symmetrical be arranged built beam regulator insert, whereby both the stability enlarged, as The design effort is further reduced significantly.
  • Especially It is advantageous if the valve piston with the valve open to a part water outlet side protrudes from the water outlet mouthpiece. Thus, the valve piston can manually, for example with a finger, in the water outlet mouthpiece back depressed if it is due to dirt and / or limescale in its open position stuck.
  • An embodiment of the invention will be explained in more detail with reference to the drawing; show it
  • 1 schematically a vertical section through a water outlet nozzle with a switchable Strahlreglereinsatz in a basic position in which emerges a sharp cleaning jet;
  • 2 schematically a vertical section through the in 1 illustrated water outlet mouthpiece with switched jet regulator insert, from which emerges a soft, enriched with air water jet;

  • 4 a side view of the in 1 illustrated water outlet mouthpiece;
  • 5 schematically the bottom view of in 1 illustrated water outlet mouthpiece.
  • This in 1 represented, in total by the reference numeral 1 provided water outlet mouthpiece for a faucet, not shown, has a jet regulator insert 2 on that in a screw sleeve 3 is arranged.
  • The screw sleeve 3 is a hollow cylinder open at its two end faces, the water inlet side 4 , in 1 above, on its outer surface 5 an outside thread 6 having. In the 4 screwed sleeve shown from the side 3 with the external thread 6 corresponds in its dimensions to a commercially available, standardized water outlet mouthpiece, so that the latter or only their Strahlreglereinsatz readily against the water outlet mouthpiece 1 or the Strahlreglereinsatz 2 is interchangeable.
  • In a water outlet side area 7 the screw sleeve 3 are two parallel flat key surfaces 8th for the forks of a fork wrench for mounting or dismounting the water outlet nozzle 1 intended.
  • The jet regulator insert 2 includes a jet regulator body 9 , which in its outer dimensions of the Innemaßen the screw 3 So that corresponds to a conventional Strahlreglereinsatzes and is inserted from above in this. To prevent it from slipping down, the jet regulator body points 9 along its upper edge an outwardly projecting circumferential collar 10 on, on a complementary level 11 on the inner circumferential surface of the screw sleeve 3 touches down.
  • Above the collar 10 is a flat gasket 12 arranged in the installed state between the collar 10 and a corresponding, not shown surface of the spout of the faucet is clamped in a conventional manner and seals the connection.
  • The jet regulator body 9 is above with a flat annular lid 13 closed, in its center a water inlet opening 14 having. The lid 13 closes with the collar 10 flush upwards, leaving the flat gasket 12 In addition, the area between the collar 10 and the lid 13 seals.
  • Above the water inlet 14 is on the lid 13 a cone-shaped sieve 15 detachably arranged, the tip of which is directed upwards. The sieve 15 on the lid 13 of the water outlet mouthpiece 1 is in 3 shown in plan view.
  • The water outlet side 7 the beam regulator body 9 gets through a floor 16 completed in the bottom view in 5 a variety of continuous in neren or external water outlet nozzles 17 are arranged along two concentric circles. In the middle, the floor points 16 a circular through hole 18 through, through which a hollow valve piston 19 a valve 20 is guided, with the manner explained below below the water inlet opening 14 of the lid 13 lying inflow openings 21 to inner and outer flow chambers 22 . 23 the beam regulator body 9 to be controlled.
  • The outer water outlet nozzles 17 lead out of the outer flow chambers 23 out, above the ground 16 along the inner circumferential surface of the jet regulator body 9 are arranged.
