Description

Technical Field

[0001] The present invention relates to a water outlet element for a sanitary fitting having a basic element defined for connection with a water outlet section and having a valve device that works in conjunction with the basic element, the valve device being adjustable, in particular rotatable, relative to the basic element for switching between at least two separate water guide sections between at least two switching positions, wherein the basic element has at least one discharge opening on the outflow side and each water guide section is provided with at least one inflow opening on the inflow side of the valve device. Background Technology

[0002] Such water outlet elements are known from practice in various different implementations. Summary of the Invention

[0003] The objective of this invention is to provide a water outlet element of the type mentioned at the beginning, which enables efficient sealing of the at least two water guides between the basic element and the valve device.

[0004] To address this task, a water outlet element is proposed. Specifically, in the case of water outlet elements of the type mentioned at the beginning, it is proposed that the base element has a sealing element, which, in each of the at least two switching positions, seals the transition between at least one discharge opening on the outflow side of the base element and at least one inflow opening on the inflow side of the switched water guide. In this way, the at least two individually switchable water guides of the water outlet element can be separated from each other by means of only one sealing element, and in each of the at least two switching positions of the valve device, a seal can be made relative to the base element at the transition between the base element and the valve device, through which the corresponding switched water guide extends.

[0005] In one embodiment of the water outlet element, the base element has a sealing element receiving portion in which the sealing element is disposed. In this way, the sealing element is reliably secured to the base element when the base element and the valve device are adjusted relative to each other for switching between the at least two switching positions. Through the relative adjustment of the valve device and the base element relative to each other, the sealing element positioned in the sealing element receiving portion can also be moved to different sealing positions corresponding to the respective switching positions.

[0006] For example, the sealing element receiving portion may include or be constructed in a receiving groove in the base element, and the sealing element may be held fixed in the receiving groove, for example, with respect to the relative movement between the valve device and the base element.

[0007] In one embodiment of the water outlet element, the seal receiving portion and / or sealing element, as mentioned above, are arranged and / or constructed such that, in each of the at least two switching positions, the projection of the inlet opening onto the base element—especially at right angles—lies within the outer edge of the seal receiving portion, especially within the outer edge of the sealing element, and / or within the cross-section of the base element defined by the seal receiving portion. This ensures that, in each of the at least two switching positions of the valve device, the inlet opening on the inflow side of at least two water guides, which are separated from each other, is arranged relative to the sealing element such that a sealed water guide is formed through the base element, the at least one outlet opening on the outflow side of the base element, and the at least one inlet opening on the inflow side of the valve device, which in turn is brought to the through-flow position in the corresponding switching position.

[0008] For example, the sealing receiving portion can be constructed on the outflow side of the basic element. Furthermore, it is feasible for the inlet openings of at least two of the water guides to differ from each other in shape and / or size.

[0009] In one embodiment of the water outlet element, the at least one discharge opening of the basic 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.

[0010] It should be mentioned in this regard that, in one embodiment of the water outlet element, two outflow-side discharge openings may be provided on the basic element, and these discharge openings preferably have the same opening cross-section. Corresponding to the at least two discharge openings with the same opening cross-section of the basic element, the valve device also has two inflow-side inlet openings for each of its at least two switching positions. Here, the inflow-side inlet openings of the valve device (the inflow-side inlet openings of the valve device are configured for a water guide) may have the same opening cross-section.

[0011] In one embodiment of the water outlet element, the sealing element receiving portion for the sealing element is configured to be continuous. For example, the sealing element receiving portion may be a continuous receiving groove.

[0012] In one embodiment of the water outlet element, the base element has a threaded fitting on its inlet side. In this way, the base element can be threadedly connected to corresponding mating threads, such as mating threads of another element of the water outlet element and / or mating threads of sanitary fittings.

[0013] Furthermore, the base element has a protrusion on its outflow side, through which the valve device can be connected to or is connected to the base element. The protrusion allows the base element and the valve device to be interconnected as a single unit. In this regard, it is advantageous for the valve device to have a corresponding insertion receiving portion on its inflow side for the protrusion of the base element.

[0014] It should be mentioned in this regard that a reverse arrangement of the protrusion and the insertion receiving portion is also conceivable. Therefore, in one embodiment of the outlet element, the valve device may have a protrusion on its inflow side for connection with the base element. Correspondingly, the base element may have an insertion receiving portion for the protrusion of the valve device.

[0015] The protrusions mentioned above can be constructed in annular form. Alternatively, the protrusions of the basic element can be integrally molded onto the basic element. It is also possible for the valve device to have protrusions that are annular and / or integrally molded onto the valve device. Elements without protrusions, i.e., either the valve device or the basic element, can be inserted into the protrusions for connecting the valve device to the basic element.

[0016] The outlet element may have an actuating element by means of which the valve device can be adjusted relative to the base element. Preferably, the valve device can be rotated relative to the base element by means of the actuating element of the outlet element so that the valve device and the base element can be switched relative to each other between at least two switching positions of the at least two water guides that are separated from each other.

[0017] At least a portion of the valve assembly and / or basic element, particularly the protrusions of the basic element as mentioned above, may be at least partially arranged within a receiving space defined by the actuating element. For this purpose, the actuating element may be configured as an actuating sleeve that receives at least a portion of the basic element and / or valve assembly within itself. In one embodiment of the actuating element, the actuating element has an actuating wing that may, for example, project radially outward from the base of the actuating element to allow good access for the user of the outlet element.

[0018] The control element can be configured to control the valve device such that one of the at least two separate water guides is switched on and remains switched on until the user switches to the other water guide.

[0019] In one embodiment of the water outlet element, the basic element is configured to have at least two discharge openings on the outflow side. In this regard, it is feasible for each water guide to also have a corresponding number of inflow openings on the inflow side.

[0020] When the water guide is switched, the right-angle projection of the inlet opening on the inflow side of the switched water guide onto the base element can be located within the outlet opening of the base element.

[0021] The sealing element has a plurality of separate through-openings, which correspond to multiple outflow-side discharge openings of the base element. In a preferred embodiment, the base element has two outflow-side discharge openings. Correspondingly, the sealing element has two separate through-openings, wherein a corresponding through-opening mates with one of the two outflow-side discharge openings of the base element. Here, the sealing element can be configured as an hourglass or figure-eight shape. For example, this shape can be formed by a narrowing portion of the sealing element between the two through-openings.

[0022] The through opening of the sealing element and the discharge opening on the outflow side of the basic element can each have a pair of corresponding geometric structures. In this way, the discharge opening on the outflow side of the basic element can be reliably sealed by means of the sealing element.

[0023] The present invention is described in more detail below with the aid of embodiments, but is not limited to the embodiments shown. Other embodiments are obtained by combining one or more features of the various embodiments. Attached Figure Description

Detailed Implementation

[0025] In the following description of different embodiments of the invention, elements that are functionally consistent have consistent reference numerals even when their designs or shapes differ.

[0026] All the accompanying drawings show at least a portion of the water outlet element, generally indicated by 1. The water outlet element 1 is suitable for fitting into or onto a sanitary fitting. Each water outlet element 1 has a base element 2, which is defined for connection with the water outlet portion of the sanitary fitting. Furthermore, each water outlet element 1 includes a valve device 3 that interacts with the base element 2, the valve device being adjustable relative to the base element 2 and rotatable in specific embodiments of the water outlet element 1 for switching between at least two switching positions and at least two separate water guides 4 and 5.

[0027] Each basic element 2 has at least one discharge opening 6 on the outflow side. In the specific embodiment of the water outlet element 1, two discharge openings 6 are provided, and each water guide 4 and 5 is respectively provided with two inflow openings 7 and 8 on the inflow side of the valve device 3.

[0028] As shown in the accompanying drawings, the basic element 2 has two outflow-side discharge openings 6. Correspondingly, each of the two water guides 4 and 5 has a corresponding number of inflow-side inlet openings 7 and 8, which in the illustrated embodiment are two inflow-side inlet openings 7 and 8 respectively.

[0029] In all the water outlet elements 1 shown, the corresponding basic element 2 is provided with a sealing element 9, which can be used to seal the transition between the discharge openings 6 on the two outflow sides of the basic element 2 and the inlet openings 7 or 8 on the two inflow sides of the water guide 4 or 5 that are respectively switched to in each of the at least two switching positions.

[0030] The accompanying drawings show that the corresponding basic element 2 has a sealing element receiving portion 10, in which the sealing element 9 is arranged. For example, according to... Figure 21 and 22 It can be clearly seen that the sealing receiving portion 10 and the sealing element 9 are arranged and configured such that in each of the at least two switching positions, the right-angle projections of the two entry openings 7 and 8 onto the basic element 2 are located within the outer edges of the sealing receiving portion 10 and the sealing element 9, and further within the cross-section of the basic element 2 defined by the sealing receiving portion 10.

[0031] Figure 21 The sealing element receiving portion 10 with sealing element 9 is shown when the valve device 3 is in the first switching position. It can be clearly seen that the inlet opening 7 on the inflow side of the valve device 3 is arranged such that the vertical projection of the inlet opening 7 onto the basic element 2 is located within the outer edge of the sealing element receiving portion 10 and the outer edge of the sealing element 9, and further within the cross section of the basic element 2 defined by the sealing element receiving portion 10.

[0032] When the valve device 3 is in the second switching position, the inlet opening 8 on the inflow side of the second water guide portion 5 of the valve device 3 also functions similarly. This is based on Figure 22 It can be seen clearly.

[0033] according to Figure 8-10 The sealing receiving part 10 is constructed at the outflow side 11 of the basic element 2. The inlet opening 7 of the water guide part 4 is significantly different in shape and size from the inlet opening 8 of the second water guide part 5 of the valve device 3.

[0034] At least one of the two discharge openings 6 of the basic element 2 and the inlet opening 7 or 8 of one of the at least two water guides 4, 5 of the valve device 3 has the same cross-section or at least substantially the same cross-section. Figure 21 and 22 This is the inlet opening 8 on the inflow side of the second water guide section.

[0035] When the water guides 4 and 5 are switched, the right-angle projections of the inlet openings 7 and 8 on the inflow side of the water guides 4 and 5 that are switched to are arranged in the outlet opening 6.

[0036] The sealing element receiving portion 10 is constructed as a continuous receiving groove and receives the sealing element 9 therein. The sealing element 9 may be referred to as an 8-shaped sealing ring or an hourglass-shaped sealing ring. The sealing element 9 is constructed such that it can seal the transition between the discharge opening 6 on the outflow side of the basic element 2 and the inflow opening 7 or 8 on the inflow side of the correspondingly switched water guide portions 4 and 5.

[0037] For this purpose, the sealing element 9 has a plurality of through openings 19 that are separated from each other, and these through openings correspond to the plurality of discharge openings 6 on the outflow side of the basic element 2 and the plurality of inflow openings 7 or 8 on the inflow side of the water guides 4, 5. In the illustrated embodiment, the sealing element 9 has two through openings 19 that are separated from each other, and is configured as an hourglass shape or a figure-eight shape as previously described.

[0038] The through opening 19 of the sealing element 9 and the discharge opening 6 on the outflow side of the basic element 2 have corresponding geometric structures in pairs.

[0039] The through openings 19 are separated from each other by the narrow portion 20 of the sealing element 9. Thus, the space outside the through openings 19 can be utilized.

[0040] The accompanying drawings illustrate that the basic element 2 has a threaded connector 13 on its inflow side 12, which can be used to tighten the basic element, for example, at the outlet of a sanitary fitting.

[0041] The basic element 2 has a protrusion 14 on its outflow side 11, through which the valve device 3 is connected to the basic element 2. The protrusion 14 is annular and integrally formed onto the basic element 2, i.e., integrally formed on the outflow side 11. In the use position, the valve device 3 is inserted into the protrusion 14 of the basic element 2.

[0042] The water outlet element 1 has an operating element 15, by means of which the valve device 3 can be adjusted, i.e. rotated, relative to the basic element 2 in order to switch between two separate water guides 4 and 5.

[0043] In the two water outlet elements 1 shown in the figure, the operating element 15 is configured such that the protrusion 14 of the valve device 3 and the basic element 2 is at least partially arranged within the receiving space 16 defined by the operating element 15. Therefore, the operating element 15 is an operating sleeve that can at least partially receive the protrusion 14 of the valve device 3 and the basic element 2 therein.

[0044] Importantly, on the one hand Figure 1-22 The water outlet element shown in the image and on the other hand in Figure 23-28 The difference in the water outlet element 1 shown is the shape of its operating element 15.

[0045] Each of the control elements 15 has at least one control wing 17. In the water outlet element 1... Figure 23-28 In the embodiment shown, the control element 15 has three control wings 17 evenly distributed around the longitudinal central axis of the control element 15 as working surfaces for comfortable operation of the valve device 3 connected to the control element 15.

[0046] The corresponding operating element 15 is configured to operate the valve device 3 connected to the operating element such that one of the at least two separate water guides 4, 5 is turned on and remains turned on until the user switches to the other water guide 4 or 5 again.

[0047] Figure 3 and Figure 4 Also shown is a jet splitter 18, which is based on Figure 3 and Figure 4 The exploded view of the water outlet element 1 is a part of the valve device 3 of the water outlet element 1.

[0048] This invention relates to improvements in the field of sanitary technology. Therefore, a water outlet element 1 for sanitary fittings is proposed, the water outlet element having a base element 2 and a valve device 3 connected to the base element 2, the valve device being adjustable relative to the base element 2 for switching between at least two separate water guides 4, 5 between at least two switching positions. To seal the transition between the discharge opening 6 on the outflow side of the base element 2 and at least one inlet opening 7 or 8 on the inflow side of the switched water guide 4 or 5, the base element 2 has a sealing element 9. This sealing element is configured to seal the corresponding transition between the discharge opening 6 on the outflow side of the base element 2 and the at least one inlet opening 7 or 8 on the inflow side of the switched water guide 4, 5 in each of the at least two switching positions.
