DETAILED DESCRIPTION
(29) FIGS. 1 to 16 illustrate three embodiments 1, 10, 100 of a sanitary outlet unit. The sanitary outlet units 1, 10, 100 illustrated here have a housing 2 which can be installed on the water outlet of a sanitary outlet fitting (not illustrated further here). On its outlet end side, the housing 2 has a jet former 3, which has throughflow channels 4 which are arranged on the outlet end side of the outlet units 1, 10, 100. These throughflow channels 4 divide up the water flowing out of the jet former 3 into visibly separated individual jets.
(30) While the throughflow channels 4 of the outlet units shown in FIGS. 1 to 12 are arranged on a circular path, the throughflow channels 4 of the outlet unit shown in FIGS. 13 to 16 are arranged on two spaced-apart lines L, L′ which are preferably arranged parallel to each other.
(31) From an overall view in particular of FIGS. 5 to 9, it becomes clear that the throughflow channels of the outlet unit 1 have a longitudinal axis 13 which is inclined both in the longitudinal housing axis 12 (cf. FIG. 6) and in a circumferential direction (cf. FIGS. 7 to 9). All the throughflow channels 4 here have the same angle of inclination.
(32) The jet former 3 of the outlet units 1, 10, 100 is designed here in the form of a perforated plate. While the throughflow channels 4 in the jet former 3 of the outlet units 1, 10 are arranged on at least one circular path, the throughflow channels 4 of the outlet unit 100 shown in FIGS. 13 to 16 are provided on at least two spaced-apart lines L, L′. This perforated plate forming the outlet end side of the housings 2 can also be connected integrally to the housing 2.
(33) It can be seen in FIGS. 1 and 10 that the jet former 3 has arranged upstream of it a jet divider 5, by which the water flowing through is divided up into a multiplicity of individual jets. The jet divider 5 of the outlet units 1, 10 shown in FIGS. 1 and 10 is designed here in the form of a cup-like diffuser 6, which, on the circumferential wall of its cup shape, has divider openings 7 which are arranged at uniform distances in the circumferential direction. The cup base of the cup-like diffuser 6 is provided as a baffle plate 8, by means of which the water flowing through is deflected to the divider openings 7. The divider openings 7 open out on the outer circumference of the diffuser 6 in an annular gap which tapers in the throughflow direction. For this purpose, the diffuser 6 is engaged around by a diffuser ring 8, wherein the annular gap is arranged between the diffuser 6 and the diffuser ring 8.
(34) The outlet unit shown in FIG. 10 additionally has a throughflow-quantity regulator 9 which adjusts the water flowing through to a maximum throughflow volume in a pressure-independent manner. This throughflow-quantity regulator 9 is arranged upstream of the jet divider 5, as seen in the flow direction. Instead of the throughflow-quantity regulator 9, use can also be made here of a flow restrictor (not shown further here) which narrows the throughflow cross section in this region and likewise reduces the water consumption.
(35) From a comparison of FIGS. 1 and 10, it becomes clear that an attachment screen or filter screen 11 is arranged upstream of the jet divider 5 and optionally also the throughflow-quantity regulator 9 of the outlet units 1, 10, as seen in the flow direction, and is intended to retain and filter out the limescale and dirt particles which are entrained in the water and which could otherwise impair the function of the following constituent parts of the outlet units 1, 10 and in particular of the jet divider 5, the throughflow-quantity regulator 9 and the jet former 3.
(36) From an overall view of FIGS. 5 to 9, it can be seen that the throughflow channels 4 are inclined in the direction of the longitudinal housing axis 12 such that the outflowing individual jets form, at a distance from the jet former and preferably before arriving in a water basin, an annular zone which is smaller than the possibly outer circular path comprising the throughflow channels 4 of the jet former 3.
(37) FIGS. 11 and 12 show the outlet jet pattern formed by the individual jets flowing out of the outlet units 1, 10. As FIGS. 11 and 12 show, said individual jets form an interwoven outlet jet pattern which tapers in certain regions and is esthetically particularly attractive.
(38) The outlet unit 100 shown in FIGS. 13 to 16 has a jet former 3 with throughflow channels which are arranged on spaced-apart lines L, L′ which are preferably arranged parallel to each other. The throughflow channels 4 which are arranged on at least one line and are provided here on both lines L, L′ each have a longitudinal axis 13 which in a is both inclined, in relation to the longitudinal housing axis 12 in the direction of the adjacent line of throughflow channels 4 and is angled, in respect of the plane of the outlet end side of said The sanitary outlet unit, in relation to said outlet end side by an angle other than 90°. All the throughflow channels here along the line have the same angles of inclination, wherein the throughflow channels 4, which are arranged on the lines L, L′ assigned to one another in pairs, are arranged with point symmetry in relation to one another. It can be seen from FIGS. 14 to 16 that the individual jets emerging from the jet former 3 of the outlet unit 100 here form an outlet jet pattern which is seemingly curved in an interwoven or mesh-like manner in side view, wherein the section plane of the individual jets intersecting one another along a line is intended to be arranged at a distance above a wash basin or collecting basin. The outlet unit 100 shown in FIGS. 13 to 16 is also distinguished by an esthetically particularly attractive outlet jet pattern.
(39) FIGS. 17 to 25 show a further exemplary embodiment according to the invention of a sanitary outlet unit. Components and functional units which are identical or similar in terms of function and/or structure to the preceding exemplary embodiments are denoted here with the same reference signs and are not described separately again. The statements regarding FIGS. 1 to 16 therefore apply correspondingly to FIGS. 17 to 25.
(40) The exemplary embodiment as shown in FIGS. 17 to 25 differs from the preceding exemplary embodiments at least in that the throughflow channels 4 are not formed cylindrically, but rather in a conically tapering manner. FIGS. 18 to 25 in particular show here that the cones are each positioned obliquely with respect to the longitudinal housing axis 12. The section C-C is positioned parallel to the tangential direction 15 in a throughflow channel 4 against the closed path which connects all of the throughflow channels 4 and runs in a circular manner here. FIG. 22 accordingly shows a section which runs in a plane which is defined by the longitudinal housing axis 12 and the tangential direction 15. It can be seen that the outflow direction 14, which is provided by the orientation of the throughflow channel 4 and in particular the longitudinal axis 13 thereof, is rotated in said plane in relation to the longitudinal housing axis 12 and therefore takes up an angle with the longitudinal housing axis 12. The section A-A is positioned along a complementary direction 16, which is perpendicular to the tangential direction 15, and therefore runs in a plane which is defined by the longitudinal housing axis 12 and the complementary direction 16. It can therefore be seen in FIG. 23 that the outflow direction 14 is also rotated counter to the longitudinal housing axis 12 in this plane and therefore is at an angle to the longitudinal housing axis 12.
(41) The described inclinations of the longitudinal channel axes 13 are formed here by the fact that the cones of the throughflow channels 4 each have geometrical center axes which are tilted in relation to the longitudinal housing axis 12 in the two planes mentioned.
(42) The opening angles of the individual cones are selected here to be of such a size that no undercuts are formed along the longitudinal housing axis 12 from the inflow side. It is therefore possible for demolding of a mold to take place in a simple manner.
(43) FIG. 26 shows a modification of the exemplary embodiment as shown in FIGS. 17 to 25, in which use is additionally made of a throughflow-quantity regulator 9.
(44) The angle details apparent in the figures serve merely for illustrating the preferred exemplary embodiments and may be realized differently in further exemplary embodiments.
(45) In the case of a sanitary outlet unit, it is therefore proposed to form throughflow channels 4 in a jet former 3 in such a manner that an outflow direction 14 predetermined by each throughflow channel 4 is oriented in a manner tilted in relation to a longitudinal housing axis 12 in two planes perpendicular to each other and/or about two directions perpendicular to each other.
