Definitions

• the invention relates to a sanitary functional unit, which can be used as an insert cartridge in a liquid guide a sanitary outlet fitting and has a housing, a jet regulator and an inflow-side attachment screen.
• Such a sanitary functional unit is known, for example, from WO 2004/038112 A1. Although this sanitary 10 functional unit has proven itself, it can still be improved.
• the housing carries on the outside an external thread which can be screwed into an internal thread of the outlet fitting, that
• the functional unit of the invention thus consists essentially only of two, comparatively easy to produce main components, namely the housing and the Strahlzerlegerteil that are connected to each other and then
• annular shoulder is provided on Strahlzerlegerteil, preferably the outer peripheral side, which acts in the use position the inflow-side end edge region of the housing.
• the housing as well as the jet splitter part which can be connected to it each have a preferably circumferential detent formation, which engage in one another in the assembly position.
• the two parts can thereby simply be clipped together, but if necessary, also be separated from each other again.
• the provided on the housing part external thread and the ring seal allow direct installation in the liquid management of a sanitary outlet fitting, without the need for these parts-male thread / ring seal-exhibiting intermediate holder is required. This simplifies the manufacture and assembly.
• the separability of the housing part and the Strahlzerlegerteils is particularly advantageous if the functional properties of the jet regulator to be changed.
• the housing perforated plate which is preferably designed as a honeycomb plate
• the perforated plate of the beam decomposer part a space for accommodating one or more rust-like insert parts is provided in spite of the small total structural length.
• the dimensioning of the housing length such that the external thread and preferably immediately adjacent
• Ring seal has space, with almost immediately adjoins the external thread of the inflow-side housing edge, resulting in a very compact structure, through which the
• Function unit can also be used in outlet fittings, for example, for design reasons, little space for receiving the
• the internal thread of the outlet fitting at a distance from the mouth thereof, which is smaller than the distance of the housing-ring seal from the inner end of the housing external thread.
• the threaded connection already engages during assembly of the functional unit before the ring seal enters the outlet fitting, so that, in particular, a manual assembly process is considerably simplified.
• disassembling the ring seal can be moved by rotating the functional unit in the axial direction of the fitting seat until it is disengaged and before the threaded connection is released.
• This assembly and disassembly simplification is of particular importance because the insert cartridge is arranged as a "hidden Einsetzpatrone" with at least the majority of its longitudinal extent, preferably completely with its entire longitudinal extent in the fitting outlet.
• the Strahlzerlegerteil on the inflow side on an insertion opening for the attachment screen with an outer ring wall and a support shoulder, wherein the holding elements for attaching the attachment screen are formed as locking elements and wherein the outer ring wall on the inside an undercut and the outer edge of the attachment screen preferably a particular circumferential, in have the undercut engaging latching projection.
• the front screen can be clipped on top of the Strahlzerlegerteil thereby and is held securely. This contributes to a low manufacturing and assembly costs, since on the one hand the holding elements are integrally formed on the parts to be joined together during their production and on the other hand, the screen assembly can be made manually or automatically quickly.
• the inflow-side annular wall of the jet fragmentation part and at least a part of the outer edge of the attachment screen form a stop abutting in the assembly position on an insertion stop in the outlet fitting.
• the insertion stop of the outlet fitting covers partially or completely the Siebrand, so that the front screen is held securely even under unfavorable conditions.
• the housing is formed integrally with a downstream perforated plate as part of the jet regulator.
• a preferred development of the invention provides that the jet decomposition part is arranged with an integrally connected further perforated plate as part of the jet regulator and / or that the jet decomposition part has holding elements for fastening the front screen.
• sanitary functional unit 1 is designed as Einsetzpatrone 2, which can be used in a liquid guide 3 of a dashed line indicated, only one-sided outlet fitting 4.
• the functional unit 1 essentially has a housing 5 with an integrally formed, outflow-side perforated plate 6, a jet decomposing part 7 with a one-piece perforated plate 8 and a front screen 9.
• the integrally formed on the housing 5, outflow-side perforated plate 6 also serves as a vandalism protection, which effectively prevents unauthorized and leading to leaks high pressures of the housing interior of the housing 5 components.
• the housing 5 On the outside, the housing 5 carries an external thread 10 and, downstream of it, an annular seal 12 placed in an annular groove 11 downstream of it. The direction of flow is indicated by the arrow Pf 1.
• the housing 5 With the external thread 10, the housing 5 is screwed into an internal thread 13 of the outlet fitting 4 and seals by means of the ring seal 12 against the inner wall 14 of the outlet fitting 4 from. Good to see here is that the internal thread of the outlet fitting 4 is set back inside, so that the ring seal 12 comes into a thread-free area to the plant.
• the internal thread .13 of the outlet fitting 4 on the one hand and the ring seal 12 of the housing 5 on the other hand are arranged so that the threads already engage when the ring seal 12th is still outside the outlet fittings-mouth 15.
• the internal thread 13 of the outlet fitting 4 has a distance a from the mouth 15, which is smaller than the distance b of the housing-ring seal 12 from the inner end of the housing external thread 10. This also causes when unscrewing the Insert cartridge 2 from the outlet fitting 4, the threads remain in engagement until the ring seal 12 exits the mouth 15 or leaked.
• the jet disintegrator part 7 and the housing 5 engage with each other in the position of use with a partial region of their longitudinal extent.
• an annular shoulder 40 is provided on the jet disintegrator part 7 or on the housing 5 on the inside or outside circumference, which acts in the position of use on the end edge region 41 of the respective other component 57. From the figure it is clear that here the jet breaker part 7 carries the annular shoulder 40, the in Use position the inflow-side end edge portion 41 of the housing 5 acted upon. In this case, the jet breaker part 7 is connected by a latching connection 16 with the housing 5.
• the latching connection 16 is located on the housing edge 17, which adjoins directly to the external thread 10 of the housing 5.
• the housing edge 17 has an annular groove 32 on the inside, while the jet decomposition part 7 has an annular bead 33 engaging in the annular groove.
• Both Rastanformept are preferably formed circumferentially.
• the intended latching connection 16 is designed so that the jet fragmentation part 7 can be removed from the housing 5 and then the housing interior is accessible.
• the attachment screen 9 is connected by means of a latching connection 20 with the jet disintegrator part 7.
• This jet decomposition part 7 has an insertion opening 21 with an outer annular wall 22 and a support shoulder 23 on the upper side or on the inflow side.
• the annular wall 22 has on the inside an undercut 24 and the outer edge 25 of the attachment screen 9 a particular circumferential, engaging in the undercut 24 locking projection 26.
• the attachment screen 9 can thereby be clipped from the inlet side into the insertion opening 21 of the jet disintegrator part 7 and is therefore safe with the Strahlzerlegerteil 7 connected.
• the part of the insertion cartridge 2 to be connected to one another ie the housing 5, the jet disintegrator part 7 and the attachment screen 9, themselves have integral connecting elements, they can be connected to one another without the need for additional holders.
• the housing 5 of the Einsetzpatrone 2 may have a profiled outer contour and / or a profiled Abström end face to Have attachment of an assembly tool.
• a profiled ring edge 29 is provided on the outflow side, on which a mounting tool for screwing in and unscrewing the insertion cartridge 2 can be attached. It is particularly advantageous if this profiling of the annular rim is designed such that a further insertable cartridge 2 can be used in reverse position as an assembly tool and can engage with its annular edge profiling in the insertable cartridge 2 to be screwed in or removed.
• the annular rim 29 has annular wall sections 30 with interruptions 31 located therebetween. The interruptions 31 are dimensioned in the circumferential direction in such a way that the annular wall sections 30 fit into an identically formed further insertion cartridge 2. Instead of this profiling, differently configured profilings can be provided.
