Description

[0001] The invention relates to an outlet element for a sanitary fitting with a base element intended for connection to an outlet and with a valve device which interacts with the base element and which is adjustable, in particular rotatable, relative to the base element for switching between at least two separate water guides between at least two switching positions, wherein the base element has at least one outflow-side outlet opening and each water guide is assigned at least one inflow-side inlet opening of the valve device.

[0002] Such outlet elements are already known in practice in a wide variety of designs. One outlet element is already known from the document CN 110 159 797 A. The document DE202011050534U1 discloses an outlet element with the features of the preamble of claim 1.

[0003] The object of the invention is to provide an outlet element of the type mentioned above which enables efficient sealing of the at least two water guides between the base element and the valve device.

[0004] To achieve this object, an outlet element having the features of independent claim 1 directed to an outlet element is proposed. To achieve the object, in an outlet element of the type mentioned at the outset, it is thus particularly proposed that the base element has a sealing element with which, in each of the at least two switching positions, a transition between the at least one downstream outlet opening of the base element and the at least one upstream inlet opening of the switched water guide can be sealed. In this way, the at least two separately switchable water guides of the outlet element can be separated from one another using only one sealing element, and the transition between the

[0005] Base element and the valve device, through which the respectively switched water supply runs, are sealed in each of the at least two switching positions of the valve device relative to the base element.

[0006] In one embodiment of the outlet element, the base element has a seal receptacle in which the sealing element is arranged. This makes it possible to reliably secure the sealing element to the base element when the base element and the valve device are adjusted relative to one another to switch between the at least two switching positions. By adjusting the valve device and the base element relative to one another, the sealing element positioned in the seal receptacle can also be moved into different sealing positions associated with the respective switching positions.

[0007] The seal receptacle may, for example, comprise or be a receiving groove formed in the base element, in which the sealing element can be held in a form-fitting manner, for example with respect to a relative movement between the valve device and the base element.

[0008] In one embodiment of the outlet element, it is provided that a seal receptacle, for example the one already mentioned above, and / or the sealing element are arranged and / or designed such that, in particular rectangular, projections of the inlet openings onto the base element in each of the at least two switching positions lie within an outer edge of the seal receptacle, in particular of the sealing element and / or within a cross-section of the base element delimited by the seal receptacle.In this way, it is ensured that in each of the at least two switching positions of the valve devices, at least one inflow-side inlet opening of the at least two separate water guides is arranged relative to the sealing element in such a way that a sealed water guide is created through the base element, its at least one downstream outlet opening, and the at least one inflow-side inlet opening of the valve device, which is brought into a throughflow position in the respective switching position.

[0009] The seal receptacle can, for example, be formed on a downstream side of the base element. Furthermore, it is possible for the inlet openings of at least two of the water guides to differ from one another in terms of shape and / or size.

[0010] In one embodiment of the outlet element, it is provided that the at least one outlet opening of the base element and the at least one inlet opening of one of the at least two water guides of the valve device have the same cross-section.

[0011] At this point, it should be noted that in one embodiment of the outlet element, two downstream outlet openings can be provided on the base element, which preferably have matching opening cross-sections. Matching the at least two outlet openings with matching opening cross-sections of the base element, the valve device can then also have two upstream inlet openings for each of its at least two switching positions. The upstream inlet openings of the valve devices, which are assigned to a water line, can have matching opening cross-sections.

[0012] In one embodiment of the outlet element, it is provided that the seal receptacle for the sealing element is endless.

[0013] The seal receptacle can, for example, be an endless receiving groove.

[0014] In one embodiment of the outlet element, the base element can have a threaded connector on its inflow side. This allows the base element to be screwed to a corresponding mating thread, for example, of another element of the outlet element and / or a sanitary fitting.

[0015] Furthermore, the base element can have an extension on its downstream side, via which the valve device can be connected or is connected to the base element. Using the extension, the base element and the valve device can be connected to form a single unit. In this context, it can be advantageous if the valve device has a corresponding plug-in receptacle for the extension of the base element on its upstream side.

[0016] At this point, it should be noted that the reversed arrangement of the extension and plug-in receptacle is also conceivable. Thus, in one embodiment of the outlet element, the valve device can have an extension on its inflow side for connection to the base element. Accordingly, the base element can then have a plug-in receptacle for the extension of the valve device.

[0017] The aforementioned extensions can be ring-shaped. Furthermore, it is possible for the extension of the base element to be integrally formed with the base element. Likewise, it is possible for the valve device to have an extension that is ring-shaped and / or integrally formed with the valve device. The element that does not have an extension, i.e., either the valve device or the base element, can then be or be slipped onto the extension for the purpose of connecting the valve device to the base element.

[0018] The outlet element can have an actuating element with which the valve device can be adjusted relative to the base element. Preferably, the valve device can be rotated relative to the base element using the actuating element of the outlet element in order to switch the valve device and the base element relative to each other between the at least two switching positions of the at least two separate water guides.

[0019] The valve device and / or at least a part of the base element, in particular an extension of the base element, for example the one already mentioned above, can be arranged at least partially within a receiving space defined by the actuating element. For this purpose, the actuating element can be designed as an actuating sleeve that accommodates at least a part of the base element and / or the valve device. In one embodiment of the actuating element, it has an actuating wing that can, for example, protrude radially outward from a base body of the actuating element in order to be easily accessible to a user of the outlet element.

[0020] The actuating element can be configured to actuate the valve device in such a way that one of the at least two separate water lines is switched on and remains switched on until the user switches back to the other water line.

[0021] According to the invention, the base element has at least two downstream outlet openings and each water guide has a corresponding number of upstream inlet openings.

[0022] In the case of switched water flow, rectangular projections of the upstream inlet openings of the switched water flow onto the base element can lie within the outlet openings of the base element.

[0023] According to the invention, the sealing element has a number of separate passage openings corresponding to a number of downstream outlet openings of the base element. In a preferred embodiment, the base element has two downstream outlet openings. Accordingly, the sealing element then has two separate passage openings, each of which is assigned to one of the two downstream outlet openings of the base element. The sealing element can be hourglass-shaped or figure-8-shaped. For example, this shape can be formed by a constriction of the sealing element between two passage openings.

[0024] The through-holes of the sealing element and the downstream outlet openings of the base element can each have corresponding geometries in pairs. This makes it possible to reliably seal the downstream outlet openings of the base element using the sealing element.

Further exemplary embodiments arise from the combination of the features of one or more claims with one another and / or from the combination of one or more features of the exemplary embodiments.

[0027] In the following description of various embodiments of the invention, elements that correspond in their function are given the same reference numerals even if they have a different design or shape.

[0028] All figures show at least parts of an outlet element, designated as a whole by 1. The outlet elements 1 are suitable for use in or on a sanitary fitting. Each outlet element 1 has a base element 2, which is intended for connection to an outlet of the sanitary fitting. Furthermore, each outlet element 1 comprises a valve device 3 that interacts with the base element 2 and is adjustable relative to the base element 2 for switching between at least two separate water guides 4 and 5 between at least two switching positions; in the specific embodiments of the outlet elements 1, this valve device is rotatable.

[0029] Each base element 2 has at least one downstream outlet opening 6. In the specific embodiments of the outlet element 1 shown, two outlet openings 6 are provided, and each water guide 4 and 5 is assigned two upstream inlet openings 7 and 8 of the valve device 3. The figures show that the base element 2 has two downstream outlet openings 6. Accordingly, each of the two water guides 4 and 5 also has a corresponding number of upstream inlet openings 7 and 8, namely two upstream inlet openings 7 and 8 in the illustrated embodiment.

[0030] In all of the outlet elements 1 shown, it is provided that the respective base element 2 has a sealing element 9 with which, in each of the at least two switching positions, a transition between the two downstream outlet openings 6 of the base element 2 and the two upstream inlet openings 7 and 8 of the respectively switched water guide 4 and 5 can be sealed.

[0031] The figures show that the respective base element 2 has a sealing receptacle 10 in which the sealing element 9 is arranged. For example, Figures 21 and 22It becomes clear that the seal receptacle 10 and the sealing element 9 are arranged and designed such that, in each of the at least two switching positions, rectangular projections of two of the inlet openings 7 and 8 onto the base element 2 lie within an outer edge of the seal receptacle 10 and also of the sealing element 9 and, moreover, within a cross-section of the base element 2 delimited by the seal receptacle 10.

[0032] Figure 21 shows the seal receptacle 10 with the sealing element 9 with the valve device 3 in a first switching position. It can be clearly seen that the inlet openings 7 on the upstream side of the valve device 3 are arranged such that vertical projections of the inlet openings 7 onto the base element 2 lie within the outer edge of the seal receptacle 10 and the outer edge of the sealing element 9 and also within a cross-section of the base element 2 delimited by the seal receptacle 10.

[0033] The same applies when the valve device 3 is in the second switching position with the inflow-side inlet openings 8 of the second water guide 5 of the valve device 3. This can be seen from the Figure 22 clearly visible.

[0034] According to the Figures 8-10 The seal receptacle 10 is formed on an outflow side 11 of the base element 2. The inlet openings 7 of the water guide 4 differ noticeably in terms of their shape and size from the inlet openings 8 of the second water guide 5 of the valve device 3.

[0035] The two outlet openings 6 of the base element 2 and at least one of the inlet openings 7 and 8 of one of the at least two water guides 4, 5 of the valve device 3 have the same cross-section or at least approximately the same cross-section. Figures 21 and 22 These are the inflow-side inlet openings 8 of the second water guide.

[0036] When the water guides 4, 5 are switched, rectangular projections of the upstream inlet openings 7, 8 of the respective switched water guides 4, 5 are arranged on the base element 2 within the outlet openings 6. The seal receptacle 10 is designed as an endless receiving groove and accommodates the sealing element 9. The sealing element 9 can be referred to as an 8-shaped sealing ring or an hourglass-shaped sealing ring. The sealing element 9 is designed such that it can seal the transition between the downstream outlet openings 6 of the base element 2 and the upstream inlet openings 7 and 8 of the respective switched water guides 4 and 5.

[0037] For this purpose, the sealing element 9 has a number of separate passage openings 19, which correspond to a number of downstream outlet openings 6 of the base element 2 and a number of upstream inlet openings 7 and 8 of a water guide 4, 5. In the illustrated embodiment, the sealing element 9 has two separate passage openings 19 and, as already explained, is hourglass-shaped or figure-8-shaped. The passage openings 19 of the sealing element 9 and the downstream outlet openings 6 of the base element 2 each have pairwise corresponding geometries. The passage openings 19 are separated from each other by a constriction 20 of the sealing element 9. Thus, space outside the passage openings 19 can be used.The figures illustrate that the base element 2 has a threaded connector 13 on its inflow side 12, with which it can be screwed, for example, onto an outlet piece of a sanitary fitting.

[0038] The base element 2 has an extension 14 on its downstream side 11, via which the valve device 3 is connected to the base element 2. The extension 14 is annular and integrally formed on the base element 2, namely on the downstream side 11. In the use position, the valve device 3 is plugged onto the extension 14 of the base element 2.

[0039] The outlet element 1 has an actuating element 15 with which the valve device 3 is adjustable, namely rotatable, relative to the base element 2 in order to switch between the two separate water guides 4 and 5.

[0040] In both outlet elements 1 shown in the figures, the actuating elements 15 are designed such that the valve device 3 and the extension 14 of the base element 2 are arranged at least partially within a receiving space 16 defined by the actuating element 15. The actuating elements 15 are thus actuating sleeves that can at least partially accommodate the valve device 3 and the extension 14 of the base element 2.

[0041] The differences between the Figures 1-22 on the one hand and in the Figures 23-28 on the other hand, the outlet elements 1 shown by the shape of their actuating elements 15.

[0042] Each of the actuating elements 15 has at least one actuating wing 17. In the Figures 23-28In the embodiment of the outlet element 1 shown, the actuating element 15 has three actuating wings 17 arranged uniformly distributed around a longitudinal central axis of the actuating element 15 as engagement surfaces for the comfortable actuation of the valve device 3 connected to the actuating element 15.

[0043] The respective actuating element 15 is designed to actuate the valve device 3 connected to it in such a way that one of the at least two separate water guides 4, 5 is switched on and remains switched on until the user switches back to the other water guide 4 or 5.

[0044] The Figures 3 and 4 also show a jet splitter 18, which according to the exploded views of the outlet element 1 of the Figures 3 and 4 is part of the valve device 3 of the outlet element 1.

[0045] The invention relates to improvements in the field of sanitary technology. A discharge element 1 for a sanitary fitting is proposed, comprising a base element 2 and a valve device 3 connected to the base element 2, which valve device can be adjusted between at least two switching positions relative to the base element 2 to switch between at least two separate water guides 4, 5. In order to seal a transition between a downstream outlet opening 6 of the base element 2 and at least one upstream inlet opening 7 or 8 of a switched water guide 4 or 5, the base element 2 has a sealing element 9. This sealing element is designed to seal the respective transition between a downstream outlet opening 6 of the base element 2 and the at least one upstream inlet opening 7 or 8 of the switched water guide 4, 5 in each of the at least two switching positions.
