Definitions

  • the invention relates to a sanitary insert, with a housing, on the downstream side of which an outlet structure is formed, and with an attachment screen which is arranged on an upstream side.
  • Such insert parts are known and are used, for example, in a fitting outlet in order to obtain a desired jet quality and / or flow rate per unit of time.
  • a non-exhaustive list of jet qualities includes, for example: ventilated jet, arrangement of individual jets, non-circular jet cross-section.
  • a flow rate regulator can be used to set a pressure-independent flow rate per unit of time within a working range. It is also known to design insert parts with a specific switching behavior, for example as a function of a water temperature. It is also known to equip sanitary insert parts with devices for switching between different jet qualities and / or flow rates.
  • Such insert parts are often composed of a cup-shaped housing and internal parts that implement the respective functionality. These parts are therefore also referred to as functional units.
  • the housing and the parts are often designed in such a way that the parts are held on their respective circumference by means of a snap connection.
  • the invention is based on the object of simplifying the structural design of a sanitary insert part.
  • Claim 1 in order to achieve the stated object in a sanitary insert part of the type mentioned at the outset, it is proposed that the attachment strainer be snapped onto the outlet structure via a connecting element extending through an interior of the housing. It is therefore not necessary to attach internal parts to their circumference.
  • the structural design is thus simplified. This can be used, for example, to provide a larger clear inner diameter for the water flow while maintaining the same external dimensions, since no radial installation space has to be reserved for peripheral fastening.
  • a functional unit is arranged in the interior of the housing, through which the connecting element is inserted.
  • the connecting element can also be used for aligning the functional unit.
  • a jet splitter through which the connecting element is inserted is arranged in the interior of the housing.
  • a lateral stabilization of the connecting element can thus be achieved.
  • a lateral fixation of the jet splitter can also be achieved.
  • the jet splitter can be designed, for example, as a diffuser with a diffuser ring or as a splitter plate.
  • At least one deflection insert is arranged in the interior of the housing through which the connecting element is inserted.
  • the deflection insert can be set up, for example, to deflect water jets emerging from a jet splitter. It is thus possible to support functional units arranged further upstream, for example the jet splitter.
  • At least one sieve insert is arranged in the interior of the housing, through which the connecting element is inserted.
  • the at least one sieve insert can thus be fixed laterally, and the connecting element can be supported laterally.
  • At least one shoulder is formed on the connecting element, on which at least one functional unit, in particular the already mentioned at least one functional unit, is supported.
  • a water pressure can be recorded which results from the fact that the functional unit, for example the already mentioned jet splitter and / or the already mentioned at least one sieve insert and / or the already mentioned deflection unit, represents a flow obstacle.
  • the arrangement of the connecting element in the interior of the housing can result in a more favorable introduction of force than the previously usual support on the circumference.
  • a functional unit for example the functional unit already mentioned, is connected to the connecting element is mad.
  • an additional axial securing can be created. This can further improve the cohesion of the components in the axial direction.
  • a snap-on interface is formed on the attachment screen.
  • the snap connection can thus be established under visual inspection.
  • a snapping interface is formed on the outlet structure.
  • the housing with the outlet structure can thus be designed in a simple manner, in particular it can be removed from the mold.
  • a snapping interface is formed in the connecting element. This makes it possible to relocate the interface that causes the snap-fit between the attachment screen and the outlet structure to any suitable location. This can be done, for example, according to the requirements of an injection molding tool and / or mechanical stability. It is also possible in this way to reinforce or lock a snap connection by means of an attached part, for example a jet splitter and / or a sieve insert.
  • several interfaces can also be formed, for example on the attachment screen and the outlet structure, on the attachment screen and in the connecting element, in the connecting element and on the outlet structure, or at all three locations.
  • the invention makes it possible - for example also in a series of sanitary insert parts with matching housings, attachment sieves and / or outlet structures and with connecting elements that differ from one another Realizing interfaces in a simple way.
  • the attachment screen is attached to the connecting element.
  • An interface that is particularly easy to manufacture and / or handle can thus be designed.
  • the connecting element is inserted into a receptacle on the outlet structure. This means that additional openings in the outlet structure can be avoided.
  • the housing is designed without undercuts in the interior at least below a jet splitter, in particular the jet splitter already mentioned.
  • a housing shape that can be easily demolded can thus be achieved at least below the jet splitter.
  • the housing is preferably designed without undercuts in the interior over its entire axial length, for example stepped.
  • snap connections on the circumferential side can be completely dispensed with.
  • circumferential support of the inner functional assemblies can thus be achieved.
  • the housing has a cylindrical inner contour at least below the jet splitter.
  • the advantage here is that diameter constrictions in the interior can be avoided.
  • the housing is preferably designed with a cylindrical inner contour over its entire axial length. It is thus possible to provide a housing that can be used universally for different functional groups.
  • the connecting element is designed as a holding mandrel. In this way, impairment of the water jet by the connecting element can be kept to a minimum.
  • the connecting element is arranged on a longitudinal center axis of the housing.
  • a symmetrical arrangement can thus be achieved in which the connecting element remains hidden as best as possible from all viewing directions.
  • the outlet structure is molded onto the housing. A stable and / or tight support of the outlet structure and the connecting element can thus be achieved.
  • the attachment screen is supported on its outer circumference on the housing. Stabilization of the insert part can thus be achieved, for example, by means of an axial support, to prevent it from falling apart in the axial direction or, by means of a radial support, to prevent it from slipping sideways.
  • the housing is designed in one piece.
  • a housing that is particularly simple in construction can thus be used, in particular if it is designed without undercuts or even cylindrical.
  • the housing is received by a screw sleeve.
  • the screw sleeve forms and / or delimits at least one ventilation channel between itself and the housing. In this way, easily ventilated jet shapes can be realized.

  • a further functional unit 9 in the form of a deflection insert 11 is designed downstream of the jet splitter 10.
  • the deflection insert 11 is formed inwardly in such a way that an emerging jet from the jet splitter 10 is deflected radially inward in order to achieve thorough mixing below the jet splitter 10.
