Definitions

  • the invention relates to jet regulators which are used on sanitary fittings, for example.
  • Such jet regulators can configure two mutually separate ducts which are disposed inside one another, wherein a splitter unit, through which a water guide of an inner duct of the two ducts is inserted, is assigned to an outer duct of the two ducts.
  • Jet regulators of this type are already known from the prior art. They can be used on sanitary fittings, for example, which per se have two different water guides, one for cold water and a second one for warm water, hot water or boiling water, for example.
  • a jet regulator of the type mentioned at the outset which has the means and features of the first independent claim directed toward a jet regulator of this type.
  • the water guide of the inner duct is latched in the splitter unit of the outer duct and, as a result, is fixed in two axial directions.
  • the splitter unit ensures that water which flows through the outer duct is split and optionally mixed with air; on the other hand, the splitter unit functions as a fastening means which fixes the water guide of the inner duct of the two ducts in two axial directions relative to the other elements of the jet regulator.
  • the water guide of the inner duct can be a water guide sleeve. Furthermore, it is possible for the water guide to have a circumferential latching groove in which the splitter unit in the latched use position of the water guide is disposed.
  • the latching groove may define a relative position of the water guide in relation to the splitter unit, and can more over have the effect of axially fixing the water guide on the splitter unit in two axial directions, in a manner which is simple in terms of construction and at the same time reliable.
  • the latching groove can be axially delimited by two shoulders of the water guide.
  • the splitter unit can be disposed between the two shoulders of the water guide and within the latching groove.
  • one of the two shoulders of the water guide in particular a downstream shoulder of the water guide, to have a lesser radial extent than the other shoulder of the water guide, the latching groove of the water guide potentially being delimited by the other shoulder.
  • the shoulder of the water guide having the lesser radial extent can be assigned a, preferably downstream, sloped ramp, for example in the form of a conical ramp, by way of which the splitter unit is able to be introduced into the latching groove of the water guide.
  • a jet regulator of the type mentioned at the outset which has the means and features of the second independent claim directed toward a jet regulator of this type.
  • a jet regulator having a splitter unit and an attachment screen which by way of an anchoring element is fastened to the splitter unit and on the outflow side engages the splitter unit from the rear.
  • the attachment screen can be fastened to the splitter unit with the aid of the anchoring element.
  • jet regulators it is provided that the latter has the features of both independent claims which are each directed toward a jet regulator.
  • the anchoring element is a water guide of the jet regulator, for example the water guide already mentioned above.
  • the water guide can be a water guide for the inner duct mentioned above.
  • the anchoring element not only assumes the function as a means for fastening the attachment screen to the splitter unit, but also as a water guide.
  • the anchoring element here can have a shoulder which on the outflow side engages the splitter unit from the rear.
  • the splitter unit in the use position can bear on the preferably downstream shoulder of the anchoring element and provide a connection between the anchoring element and the splitter unit by way of which the attachment screen is then ultimately also fixed to the splitter unit.
  • the anchoring element penetrates the splitter unit and/or the attachment screen.
  • the splitter unit and/or the attachment screen can in each case have a, preferably centric, opening through which the anchoring element, in particular the water guide, is inserted in the use position in order to fasten the attachment screen to the splitter unit.
  • the splitter unit has an upstream step.
  • the attachment screen can bear on this upstream step.
  • the attachment screen on the outflow side can in this instance be fixed axially in terms of the position thereof relative to the splitter unit and the anchoring element, in particular relative to the water guide of an inner duct, for example the inner duct already mentioned.
  • the anchoring element has an in particular upstream detent.
  • the attachment screen can bear on this detent and on the inflow side be axially secured and fixed in terms of position.
  • the attachment screen can thus be disposed between the splitter unit and the anchoring element and by said splitter unit and said anchoring element in terms of its position be fixed in two axial directions. In this way, the attachment screen in this instance is established between the splitter unit and the anchoring element fastened to the splitter unit.
  • the anchoring element is releasably connected to the attachment screen. In this way, the anchoring element can be made separately from the attachment screen.
  • the splitter unit has a splitter plate, or is configured as a splitter plate.
  • the water guide terminates above a discharge structure of the jet regulator. In another embodiment of the jet regulator it is provided that the water guide is routed through a discharge structure of the jet regulator.
  • the water guide can optionally protrude from the discharge structure, in particular a discharge structure into which the outer duct of the two ducts opens.
  • the jet regulator in the region of the water guide can have at least one attachment screen and/order at least one screen insert.
  • the at least one attachment screen and/or the at least one screen insert can have cut-outs through which the water guide of the inner duct is routed.
  • the cut-outs here can be spaced apart from the water guide. This is favorable in order to achieve that already existing attachment screens and/or screen inserts can be used together with the water guide without any constructive modifications.
  • the spacing enables a sufficient residual wall thickness in the components, which facilitates economical production, for example by plastics injection-molding.
  • a screen element can be disposed and/or configured in the water guide.
  • the screen element can be integrally molded on the water guide.
  • the splitter unit and the attachment screen are releasably or non-releasably connected to one another.
  • the respective connection can be implemented by a corresponding snap-fit connection, for example. It can be prevented by a non-releasable snap-fit connection that the attachment screen is washed away.
  • the anchoring element can be releasably or non-releasably connected to the splitter unit.
  • the respective connection can be implemented by way of a corresponding snap-fit connection, for example.
  • a releasable snap-fit connection can be characterized in that, for example, said snap-fit connection becomes softer under load, while a non-releasable snap-fit connection increasingly interlocks under load.
  • a non-releasable snap-fit connection can be established, for example, by an enclosed angle of equal to or less than 90° at the foot of an undercut.
  • a releasable snap-fit connection can be easier to produce when the demolding direction is identical to the plug-in direction of the snap-fit connection. This is because in this instance the demolding is typically carried out as a forced demolding by way of the undercut, which is difficult if the snap-fit connection is to be non-releasable, thus self-fixing. In this case, multiple-part or movable cores would have to be used, which is very expensive.
  • the two ducts on the inflow side have inlets which are mutually separate.
  • each duct of the jet regulator can have a dedicated inlet which is separate from the inlet of the other duct and can be supplied with liquid independently of the other duct and the inlet of the latter.
  • each duct it is possible for each duct to be connected separately to a liquid source assigned to the respective duct.
  • one of the two ducts can be connected to a hot water source, and the other of the two ducts can be connected to a cold-water source, for example. Potentially undesirable mixing of the liquids within the jet regulator can thus be avoided.
  • the two ducts of the jet regulator on the outflow side can have outlets which are mutually separate. It can be ensured in this way that liquid which flows through the respective duct always flows only out of that outlet that is assigned to the respective duct. This also prevents any potentially undesirable mixing of liquids within the jet regulator.
  • the jet regulator can be configured such that the two ducts are able to be simultaneously utilized. It is thus possible for both ducts to be simultaneously supplied with liquid.
  • the jet regulator can furthermore be configured such that no switching on the jet regulator is required for the operation of the ducts.
  • the two ducts can provide mutually separate flow paths and/or flow paths through the jet regulator which are able to be utilized in a mutually independent manner, in particular when said ducts have separate inlets and separate outlets. It is thus possible, for example, for the flow paths provided through the ducts to be used simultaneously. This can improve the use properties of the jet regulator and widen the field of potential uses of the latter.
  • a splitter unit in terms of function can be characterized as follows, for example: said splitter unit can force a flow onto a defined path so as to decouple downstream flow conditions from upstream factors.
  • a diffusor in terms of function can be characterized as follows, for example: said diffusor can force a flow onto a radial flow with downstream turbulence.
  • a screen element in terms of function can be characterized as follows, for example: said screen element can have a rectifying effect on a water flow.
