Description

Technical Field

[0001] This utility model relates to a sanitary discharge fitting having a fitting base and a fluid discharge insert arranged in a receiving chamber, the fitting base having a discharge section with a longitudinally extending receiving chamber. Background Technology

[0002] This type of drain fitting can be used in applications such as washbasins, bathtubs, and kitchen sinks. The fluid discharged through the drain fitting is primarily water, and the drain fitting itself is a water drain fitting. For sanitary drain fittings, it is known to releasably incorporate percolators, flow regulators, jet shapers, or filters as hygienically effective elements into the drain outlet of the drain fitting body. Through the arrangement of shut-off valves, mixing valves, etc., within the fitting body, the drain fitting can be used to discharge flow-regulated water and / or mixed water, such as mixed hot and cold water. Utility Model Content

[0003] As a technical problem, the basis of this utility model is to provide a sanitary emission fitting of the type mentioned at the beginning, which offers advantages over similar emission fittings from the prior art, particularly in terms of its components incorporated in the fitting base and its installation.

[0004] This invention solves the problem by providing a sanitary discharge accessory with the following features:

[0005] A sanitary discharge accessory, comprising:

[0006] - A fitting base with an exhaust section, the exhaust section forming a longitudinally extending receiving chamber; and

[0007] - A fluid discharge insert disposed in a receiving chamber, the fluid discharge insert having a fluid guide extending along the receiving chamber and a jet pad with a resilient ejection nozzle for discharging fluid in a jet direction not parallel to the longitudinal extension of the receiving chamber.

[0008] Its features are,

[0009] - The spray pad extends over at least one-third of the length of the receiving chamber and / or at least two-thirds of the width of the receiving chamber.

[0010] - The discharge section has an assembly port on its end side for translatably introducing the fluid discharge insert into the receiving chamber along an assembly direction parallel to the longitudinal extension of the receiving chamber, and

[0011] - An anti-loosening device is provided to prevent the fluid discharge insert from moving out of the receiving chamber in the opposite direction of the assembly direction.

[0012] Advantageous improvements of this utility model are described in the dependent claims, the full text of which thus forms part of the specification by reference.

[0013] For the discharge fitting according to this invention, the fluid discharge insert arranged in the receiving chamber has a fluid guide extending along the receiving chamber and a spray pad with a resilient ejector nozzle. The fluid discharge insert is configured to guide and discharge fluid through the receiving chamber. Fluid discharge is carried out by the ejector nozzle along a spray direction not parallel to the longitudinal extension of the receiving chamber, such as transverse, perpendicular, or at an acute angle to the longitudinal extension of the receiving chamber. If the discharge section is arranged such that it extends substantially horizontally, then fluid discharge can be carried out, for example, in a substantially downward spray direction. The longitudinal extension of the receiving chamber here refers to the direction along which the fluid is primarily guided through the receiving chamber. Correspondingly, the width refers to the direction oriented perpendicular to this longitudinal direction, extending, for example, horizontally when the discharge fitting is installed, or perpendicular to the vertical plane of symmetry of the discharge fitting.

[0014] The fluid discharge insert, utilizing the ejection nozzle, is designed to beam-shape the fluid jet to be discharged, thereby particularly functioning as a beam shaper. The ejection nozzle, due to its flexible structure, is easily cleaned. For example, a user can rub their finger across the spray pad, thereby loosening dirt, such as calcium deposits, adhering to the nozzle through the flexible movement of the ejection nozzle. Optional additional functional elements can be incorporated into the fluid discharge insert. The fitting base typically has an inflow section through which the fluid to be discharged is delivered to the discharge fitting, and this inflow section can be connected to an external fluid supply mechanism for this purpose.

[0015] The jet pad advantageously has multiple ejection nozzles, all of which are fed with the fluid to be discharged by a fluid guide. The jet pad extends over at least one-third of the length of the receiving chamber. Alternatively or supplementarily, the jet pad extends over at least two-thirds of the width of the receiving chamber. Accordingly, the ejection nozzles can be distributed over a surface that extends over at least one-third of the length and / or at least two-thirds of the width of the receiving chamber. Thus, fluid can be output as a planar jet, such as a rectangle, over a larger area of ​​the receiving chamber.

[0016] A spray pad can have a single, flexible ejector nozzle, or the entire spray pad can be made of a flexible material, with the ejector nozzle being an essential component of the overall structure of the spray pad. The ejector nozzle can be configured as a single nozzle or a nozzle strip. A single nozzle is designed to eject a point-like fluid stream, while a nozzle strip extends longitudinally in one direction and is designed to eject a linear fluid stream. Of course, a spray pad can have both a single nozzle and a nozzle strip.

[0017] The discharge section has an assembly port on its end side for translatably introducing the fluid discharge insert into the receiving chamber. The fluid discharge insert is inserted into the receiving chamber along an assembly direction parallel to the longitudinal extension of the receiving chamber. This allows for simple installation of the fluid discharge insert, which simply needs to be pushed into the receiving chamber through the assembly port. Similarly, the fluid discharge insert can be pulled out through the assembly port to remove it from the receiving chamber. "Assembly direction" here refers to the direction along which the fluid discharge insert moves during installation, that is, during insertion into the receiving chamber. When translatably introducing the fluid discharge insert into the receiving chamber, the fluid discharge insert moves substantially in a straight line.

[0018] Apart from translational pushing or pulling movements, no other movements, such as movements transverse to the longitudinal extension of the receiving chamber or rotational movements, are required for inserting the fluid discharge insert. The longitudinal extension of the receiving chamber extends parallel to the longitudinal extension of the discharge section and, when the fluid discharge insert is inserted, extends parallel to the longitudinal extension of the fluid discharge insert.

[0019] The end side with the mounting port is located at one end of the discharge section with respect to its longitudinal extension. In a preferred embodiment, the end side and the mounting port are oriented transversely to, and in particular perpendicularly to, the longitudinal extension of the discharge section, thereby allowing the mounting port to be particularly large. In particular, the mounting port can be positioned at the end of the discharge section opposite the inflow section of the fitting base, so that the fluid discharge insert moves toward the inflow section upon insertion.

[0020] The anti-loosening device prevents the fluid discharge insert from moving out of the receiving chamber in the opposite direction of assembly. Advantageously, the anti-loosening device is placed in the anti-loosening position only after the fluid discharge insert has been pushed into the receiving chamber and has reached a predetermined endpoint position on the fitting base, in which the anti-loosening device secures the fluid discharge insert, or the anti-loosening device is automatically placed in the anti-loosening position when the endpoint position of the fluid discharge insert is reached. "Endpoint position" here refers to the position in which the fluid discharge insert is arranged in the receiving chamber such that it can perform its fluid guiding and fluid discharge functions.

[0021] The anti-loosening device allows the fluid discharge insert to be secured at its final position within the receiving chamber. This ensures that the fluid discharge insert will not slip or dislodge from the receiving chamber. In particular, the anti-loosening device is releasable, allowing for the removal of the fluid discharge insert. Furthermore, the anti-loosening device preferably prevents the fluid discharge insert from being pushed further into the receiving chamber beyond its final position. Alternatively or supplementarily, a stop can be provided in the discharge section, against which the fluid discharge insert stops when pushed into the receiving chamber or upon reaching its final position. In some designs, the anti-loosening device additionally prevents the fluid discharge insert from moving laterally in the assembly direction or prevents rotation.

[0022] In summary, this invention provides a discharge fitting with an advantageous construction and simple installation. The mounting port allows for convenient and simple insertion into the receiving chamber inlet and the fluid discharge fitting. With an anti-loosening device, the fluid discharge insert can be quickly and easily secured in the receiving chamber, and this secured state can be loosened if necessary. The fluid discharge insert allows for simple replacement or maintenance.

[0023] In one improved embodiment of this invention, the anti-loosening device prevents the fluid discharge insert from moving relative to the fitting base parallel to the assembly direction by means of form-locking. Form-locking represents an easily established and reliable anti-loosening method. Furthermore, a releasable connection can be easily established by means of form-locking, provided the anti-loosening device is configured to releasably secure the fluid discharge insert. Preferably, the anti-loosening device has at least one stop pin, stop screw, or engagement connector. A single stop pin or a single stop screw is sufficient to secure the fluid discharge insert in the receiving chamber. When using one or more engagement connectors, these engagement connectors can be provided through corresponding designs of the fitting base and the fluid discharge insert. In this case, no other separate components are required to secure the fluid discharge insert in the receiving chamber. In an advantageous embodiment, the engagement connector can be configured such that it engages when the fluid discharge insert reaches its endpoint position in the receiving chamber.

[0024] In one improved embodiment of this invention, the discharge section has a guiding and retaining structure, and the fluid discharge insert has at least one guiding section. The guiding and retaining structure and the guiding section work together to guide the fluid discharge insert movably parallel to the assembly direction and prevent the fluid discharge insert from moving transversely to the assembly direction relative to the fitting base. Thus, the fluid discharge insert can be pushed into the receiving chamber in a defined position, i.e., in a defined orientation, and arranged in the receiving chamber as prescribed. Furthermore, the fluid discharge insert is completely fixed in its end position to prevent movement parallel to and transverse to the assembly direction. In particular, the guiding and retaining structure prevents the fluid discharge insert from falling out along the fluid discharge direction. In some embodiments, the guiding and retaining structure and / or the anti-loosening device further prevent the fluid discharge insert from rotating. The guiding and retaining structure and the fluid discharge insert advantageously have complementary structures.

[0025] In one improved embodiment of this invention, the guiding and retaining structure has guide tabs extending parallel to the assembly direction and opposing each other along the width direction of the receiving chamber. These guide tabs cooperate with corresponding guide sections of the fluid discharge insert. The guide tabs provide guidance for the movement of the fluid discharge insert in a particularly simple manner. Preferably, the guide tabs extend over a large portion of the length of the receiving chamber, particularly over the entire length of the receiving chamber. In an alternative embodiment, the guide tabs extend only over a small portion of the length of the receiving chamber and are divided into multiple tab sections.

[0026] In one improved embodiment of this invention, the fluid discharge insert is constructed in multiple parts and includes an insert base and a jet disc. The insert base includes a fluid guide and a jet pad. The jet disc includes a jet disc with a nozzle through-hole, in which an exit nozzle containing the jet pad is received. This structure of the fluid discharge insert offers design advantages. Therefore, the jet disc and the insert body can be designed as independently as possible according to their own requirements.

[0027] In one advantageous embodiment, the insert base is manufactured in one piece and is generally made of a resilient material. The insert base is then, for example, formed as a hollow body that functions as a fluid guide and from which the ejection nozzle extends. Alternatively, the insert base is constructed in multiple pieces, such that the injection pad and at least one additional component constitute the insert base.

[0028] The spray disc body or spray plate is preferably rigidly constructed. This improves the stability and robustness of the fluid discharge insert. Furthermore, it facilitates easier insertion of the fluid discharge insert into the receiving chamber. The nozzle through-hole is shaped such that the ejector nozzle (either a single nozzle or a nozzle strip) of the spray pad can be arranged into the nozzle through-hole and extend at least partially, but preferably completely, through it. Particularly preferred is that the ejector nozzle protrudes from the spray disc on the side of the spray disc opposite the spray pad. This allows for easy cleaning of the ejector nozzle by sweeping it across the spray disc. The portion of the ejector nozzle protruding beyond the spray disc can elastically deform, thereby dislodging any rigid dirt attached to it. In a preferred embodiment, the nozzle through-hole matches the ejector nozzle in size and shape. In particular, the ejector nozzle can be precisely positioned within the nozzle through-hole, thereby forming a form-lock between the nozzle through-hole and the ejector nozzle, which connects the insert base and the beam forming body to each other and prevents relative movement. This makes it easy to arrange the insert substrate and the beamforming body on top of each other before the fluid discharge insert is inserted into the receiving chamber.

[0029] In one improved embodiment of this invention, the spray disc has a substantially rectangular basic shape. This allows for the utilization of a larger proportion of the potential spray surface extending from the receiving chamber and provides corresponding shower spray characteristics.

[0030] In one improved embodiment of this invention, the jet disc is convexly curved. This convexity is achieved in an outward-facing direction. This allows the discharge of a fluid jet with a beam cross-section larger than the base surface of the jet disc. Furthermore, this supports a sparse jet pattern, resulting in a softer discharged fluid jet. If necessary, as an alternative or supplementary measure, arranging the ejector nozzle itself in a fan-shaped outward tilt along its longitudinal axis contributes to this. Preferably, the jet disc is curved about an axis parallel to the assembly direction. Thus, the structure of the beamformer or fluid discharge insert, especially the possible guide section, can generally extend in a straight line despite the curvature of the jet disc, thereby ensuring that the insertion of the fluid discharge insert into the receiving chamber is not interfered with by the curvature.

[0031] In one improved embodiment of this invention, the fluid discharge insert has a fluid inlet that is fluid-tightly connected to a complementary fluid outlet of the fitting base. This allows fluid to be delivered to the fluid guide portion of the fluid discharge insert while remaining sealed to the upstream section of the fitting base. In an advantageous embodiment, the connection between the fluid inlet and the fluid outlet is automatically established during installation of the fluid discharge insert by pushing the fluid discharge insert to its final position in the receiving chamber and establishing a fluid-tight connection between the fluid inlet and the fluid outlet. For this purpose, the fluid discharge insert can have a fluid inlet at its end, with the fluid inlet leading into the fitting opening. The final position of the fluid discharge insert in the receiving chamber can be predetermined by the locking connection. The fluid outlet is preferably located in the discharge section or other section of the fitting base, for example, in the transition region between the inflow section and the discharge section.

[0032] In one improved embodiment of this invention, the sanitary drainage accessory includes a handheld showerhead with a shower head and a hose. This allows for fluid drainage not only through the drainage insert but also through the shower head. This enhances the functionality of the drainage accessory. The hose allows the user to grasp the shower head and move it freely to any position to drain fluid. Preferably, fluid can be drained independently of the drainage unit and the handheld showerhead. For example, an adjustment mechanism, such as an adjustment lever, can be provided on the accessory base to adjust the fluid drainage via the drainage insert or the shower head under user control.

[0033] In one improved embodiment of this invention, the sanitary discharge fitting includes a retaining device for holding the shower head. In an advantageous embodiment, the retaining device is integrally formed with the spray disc body. The integration of the retaining device's function into the spray disc body achieves this in a space-saving and aesthetically pleasing manner. Alternatively or supplementarily, the retaining device is connected to the spray disc body by means of a locking device or other connecting means. This provides simple installation of the retaining device. Furthermore, as an alternative or supplementary embodiment, the retaining device has a contact surface against which the shower head rests when held. This provides a position-defined holding position for the shower head, facilitating operation. Additionally, as an alternative or supplementary embodiment, the retaining device has a retaining magnet that holds the shower head on the retaining device. Thus, the shower head can be detachably fixed to the retaining device in a particularly simple manner. Furthermore, the retaining magnet reliably and without wear maintains its holding capability over a long period of time. In an advantageous embodiment, the retaining magnet is integrated into the retaining body of the retaining device, particularly by die-casting it into the retaining body during manufacturing.

[0034] In one design of this utility model, the retaining device has a cylindrical abutment surface and / or an annular abutment shoulder. Preferably, a partially cylindrical abutment surface is provided, allowing the shower head to be positioned against the abutment surface from a direction parallel or transverse to the axis of the cylindrical section, on the lateral outer surface of the shower head housing. The cylindrical abutment surface is particularly complementary to the shower head housing. The annular abutment shoulder can serve as a stop for the outer surface of the end side of the shower head, particularly for the outer surface from which fluid can be discharged from the shower head.

[0035] In a preferred embodiment, the retaining device has a cylindrical abutment surface and an annular abutment shoulder such that these abutment surfaces and abutment shoulders are oriented laterally to each other and / or adjacent to each other. Thus, it is possible to predefine not only the positioning of the shower head but also its location in a simple manner while it is held in the retained state. Attached Figure Description

[0049] Figures 1 to 5 A first embodiment of the sanitary discharge fitting according to the present invention is shown and Figures 6 to 12 A second embodiment of the sanitary drain fitting according to the present invention is shown. In both cases, the drain fitting shown is a kitchen fitting for use on a kitchen sink, through which water can be drained.

[0050] As shown in the accompanying drawings, the discharge fitting according to the present invention includes a fitting base 1 with a discharge section 2 forming a longitudinally extending receiving chamber 3. In the example shown, the discharge section 2 extends generally horizontally from a vertical inflow section 24 of the fitting base 1. A fluid discharge insert 4 is received in the receiving chamber 3. The fluid discharge insert 4 has a fluid guide 5 extending along the receiving chamber 3 and a spray pad 6 with a resilient ejection nozzle 7 for discharging fluid in a spray direction not parallel to the longitudinal extension of the receiving chamber 3, particularly transverse to the longitudinal extension of the receiving chamber 3.

[0051] If the illustrated discharge fitting is operably installed and connected to an external fluid supply mechanism, fluid can first be guided through the inflow section 24 and then into the discharge section 2, where it is delivered to the fluid discharge insert 4. The fluid discharge insert 4 then guides the fluid substantially horizontally along the fluid guide section 5 and discharges it vertically downward through a plurality of ejection nozzles 7.

[0052] In some embodiments, such as the example shown, the spray pad 6 is made of a resilient material and forms the ejection nozzle 7 as an essential component of the overall structure of the spray pad 6. In the example shown, the ejection nozzle 7 is constructed as a nozzle strip through which linear fluid streams can be ejected, such as those from… Figure 3 As can be seen, multiple nozzle strips are arranged parallel to each other, thus enabling the discharge of a generally rectangular fluid stream through the exit nozzle 7.

[0053] The receiving chamber 3 has a length L along its longitudinal direction, that is, along the direction in which the fluid is mainly guided through the fluid guide section 5, and in the example shown, extends over approximately two-thirds of the length of the discharge section 2, as in Figure 4 As can be seen, the receiving chamber 3 has a width B perpendicular to the length L and perpendicular to the direction in which the fluid is discharged through the ejection nozzle 7. The spray pad 6, in the example shown, extends over approximately 80% to 90% of the length L and approximately 90% of the width B.

[0054] The discharge section 2 has an assembly port 8 at its end opposite to the inflow section 24, which is used to translately introduce the fluid discharge insert 4 into the receiving chamber 3. For this purpose, the fluid discharge insert 4 is pushed into the receiving chamber 3 along an assembly direction M extending parallel to the longitudinal direction of the receiving chamber 3, as shown in... Figure 2 As shown in the diagram. Through the assembly port 8, it can be removed from the receiving chamber 3, for example, when the fluid discharge insert 4 needs maintenance or replacement.

[0055] The anti-loosening device 9 prevents the fluid discharge insert 4 from moving out of the receiving chamber in the opposite direction of assembly M after it has been inserted into the receiving chamber 3.

[0056] In an advantageous embodiment, the anti-loosening device 9 is implemented by a single screw 25, as in Figure 2 As shown in the diagram. For installation, screw 25 is pushed in through the through hole in the fluid discharge insert 4 in a direction perpendicular to the assembly direction M and screwed into the threaded blind hole in the discharge section 2. Screw 25 thus prevents the fluid discharge insert 4 from moving along and against the assembly direction M and transversely to the assembly direction by form-locking. Therefore, the fluid discharge insert 4 is fixed in the receiving chamber 3. After loosening screw 25, the fluid discharge insert 4 can be removed from the receiving chamber 4 without any problems.

[0057] In an advantageous embodiment, the discharge section 2 includes a guide and retaining structure 10, and the fluid discharge insert, as in the illustrated example, includes at least one guide section 11. The guide and retaining structure 10 and the at least one guide section 11 cooperate to movably guide the fluid discharge insert 4 parallel to the assembly direction M. This facilitates the insertion of the fluid discharge insert 4 into the receiving chamber 3. Furthermore, the guide and retaining structure 10 and the at least one guide section 11 prevent the fluid discharge insert 4 from moving transversely to the assembly direction M relative to the fitting base.

[0058] In the corresponding implementation, the guiding and retaining structure 10 includes two guide tabs 101 and 102 that extend parallel to the assembly direction M and are opposed to each other along the width direction of the receiving chamber 3, as shown in... Figure 5 As shown in the diagram, the guide tabs 101 and 102 work in conjunction with the two complementary guide sections 111 and 112 of the fluid discharge insert 4. In addition to translating and guiding the fluid discharge insert 4, the guide tabs 101 and 102 and the guide sections 111 and 112 also prevent the fluid discharge insert from falling downwards out of the receiving chamber 3.

[0059] In advantageous implementations, as shown in the examples and especially in Figure 1 As can be seen, the fluid discharge insert 4 is divided into an insert base 12 and a jet disc 13. For example, in... Figure 1 and 10 As can be seen, the insert base 12 in the illustrated example is constructed in two parts, preferably made of a resilient material such as silicone, and includes a fluid guide body 5' with a fluid guide portion 5 and the injection pad 6. The insert base 12 forms a longitudinally extending cavity that functions as the fluid guide portion 5, and the ejection nozzle 7 exits from the cavity. The fluid is guided along the longitudinal direction of the insert base 12 along the fluid guide portion 5 and discharged perpendicularly to the fluid guide portion through the ejection nozzle 7. Thus, the fluid obtains a change of direction within the insert base 12.

[0060] The injection disc body 13 includes an injection disc 14 with nozzle through-holes 15. The injection disc body 13 is preferably made of a rigid material, such as a rigid plastic material, and thus is responsible for the corresponding stability of the fluid discharge insert 4. The ejection nozzle 7 is received in the nozzle through-holes 15. To insert the fluid discharge insert 4 into the receiving chamber 3, the insert base 12 is placed on the injection disc 14 such that the injection pad 6 abuts against the injection disc 14 and the ejection nozzle 7 is arranged in the assigned nozzle through-holes 15, for which see [reference needed]. Figure 1 and 2The nozzle through-hole 15 is precisely shaped to match the ejector nozzle 7, such that the ejector nozzle 7 is received in a form-locking manner within the nozzle through-hole 15. The insert base 12 and the injection disc 13 therefore cannot slide relative to each other. The resulting fluid exits the insert 4 and can then be pushed through the assembly port 8.

[0061] The ejector nozzle 7 extends from the ejector disc 13 on the side opposite to the insert base 12. This allows fluid to exit from the ejector nozzle 7 without interference from the ejector disc 13.

[0062] In the illustrated embodiment, guide sections 111, 112 are constructed along the injection disc 13. Because the injection disc 13 is rigid, the fluid discharge insert 4 can be pushed into the receiving chamber 3 without problems, while the flexible insert base 12 does not get stuck in the discharge section 2.

[0063] The discharge section 2 has enclosed walls on two sides and one top, which define the area of ​​the receiving chamber 3. The discharge section 2 has a downwardly extending outlet that extends over almost the entire length L and width B of the receiving chamber 3. The outlet is adjacent to the mounting port 8 at the front end of the discharge section 2.

[0064] In an advantageous embodiment, the spray disc 14 has a generally rectangular basic shape, as in the example shown, and thus matches the basic shape of the spray pad 6. When the fluid discharge insert 4 is inserted, the spray disc 14 completely fills the accessory outlet and covers the receiving chamber 3.

[0065] In an advantageous embodiment, the injection disc 14 is as follows: Figures 1 to 5 The spray pad 6 also has a convexly curved shape, just like in the example. Thus, the ejector nozzle 7, constructed in the form of a nozzle strip, extends in an arc shape. The fluid stream discharged through the ejector nozzle 7 expands accordingly. The spray valve 14 bends around an axis extending parallel to the assembly direction M, so that the spray disc 14 extends straight along its opposite edges when viewed in the width direction. Therefore, the bend does not interfere with the guiding characteristics of the fluid discharge insert 4. As an alternative or supplement to this convex bend of the spray pad 6, the ejector nozzle 7 can be arranged in a fan shape relative to the central axis of the shower spray, that is, extending with its nozzle longitudinal axis inclined to varying degrees relative to this central axis.

[0066] In an advantageous embodiment, the fluid discharge insert 4, as in the illustrated example, has a fluid inlet 16 that is fluid-tightly connected to a complementary fluid outlet 17 of the fitting base 1 when the fluid discharge insert 4 is inserted into the receiving chamber 3. The fluid outlet 17 is arranged in the discharge section 2 at the end region toward the inflow section 24. The fluid inlet 16 is located at the end of the insert base 12. The fluid inlet 16 and the fluid outlet 17 are automatically fluidly connected to each other when the fluid discharge insert 4 reaches its final position during insertion.

[0067] exist Figures 6 to 12 The embodiments shown are the same as those described above. Figures 1 to 5 The implementation shown is similar to that described above. Therefore, the following description focuses only on the implementation methods relative to those shown above. Figures 1 to 5 The differences in implementation methods will be discussed. The same reference numerals will be used for identical, functionally equivalent, or similar elements.

[0068] The fluid guide 5 passing through the insert base 12 has a flow cross-section that decreases along the direction of fluid flow in the illustrated example, preferably a linearly decreasing flow cross-section. This desirablely helps to allow fluid to exit from all the ejection nozzles 7 at the greatest possible fluid pressure.

[0069] exist Figures 6 to 12 In one embodiment, the spray disc 13 has sidewalls that extend along the length of the spray disc 23 and in which a plurality of locking slots 26 are molded, for which see Figure 7 The insert base 12 has a plurality of locking tabs 27 extending over its width, each locking tab having a locking lug 28 at its end. When the insert base 12 is placed toward the spray disc 14, the locking lug 28 engages in the locking opening 26, thereby establishing a stable, releasable connection between the insert base 12 and the spray disc 12. The fluid discharge insert 4 thus configured can then be inserted into the receiving chamber 3.

[0070] Injection disc 14 Figures 6 to 12 The example is rectangular and flat, therefore not as in Figures 1 to 5 In the case of the embodiment, it is curved. The guide tabs 101, 102 and guide sections 111, 112 are coordinated with each other so that the injection disc 14 ends flush with the outer surface of the discharge section 2. This is particularly evident in Figure 10 and 11 This can be seen from the text.

[0071] In an advantageous embodiment, the discharge fitting includes a handheld shower head 18, which has a shower head 19 and a flexible hose 20, the shower head 19 being connected to the fitting base 1 via the hose, as in... Figure 12The example illustrates this situation. The hose 20 is secured in the inflow section 24 and guides the fluid delivered by the inflow section 24 to the shower head 19. Thus, in this embodiment, fluid can be discharged not only through the fluid discharge insert 4 but also through the handheld shower head 18.

[0072] Such external reasons Figure 12 As can be seen, in this example, the fitting base 1 is mounted on a mixing assembly (Mischbatterie) having a mixing valve and a shut-off valve. The mixing ratio and the amount of fluid to be discharged can be adjusted by means of a lever and a rotary handle mounted on the mixing assembly, allowing the fluid to be discharged through the discharge fitting. Furthermore, the lever or rotary handle can adjust whether or how much fluid is delivered to the outlet section 2 and finally discharged through the fluid discharge insert 4, and whether or how much fluid is delivered to the hose 20 and finally discharged through the shower head 19. This can be designed so that, as is known, fluid discharge can be performed independently or dependently on each other through the fluid discharge insert 4 and the shower head 19. The fitting base 1 is rotatably held on the mixing assembly and can pivot about a vertical axis. Due to the flexibility of the hose 20, the shower head 19 can move independently of the pivoting position of the fitting base 1. As a supplement or alternative, the shower head 19 may optionally be twisted 360° relative to the hose 20, and / or the hose 20 may be twisted 360° relative to the fitting base 1 in the hose receiving portion of the fitting base 1.

[0073] In an advantageous embodiment, as in the example shown, a retaining device 21 is provided at the lower end of the fluid discharge insert 4, the end being away from the inflow section 24 when the fluid discharge insert 4 is in the inserted state. The retaining device 21 is configured to hold the shower head 19 and... Figures 1 to 5 In the example, it is integrally formed with the injection disc body 13. The retaining device 21 is molded onto the injection disc body 13 such that it completely covers the assembly port 8 when the fluid discharge insert 4 is inserted. Figures 6 to 12 In the example, the retaining device 21 is provided as a separate component and is latched to the spray disc 14 by means of a clip / locking device. This has the advantage that the retaining device 21 can be replaced and, for example, matched to the shower head 19.

[0074] Figures 1 to 5 The emission accessories in the implementation method can also be provided, for example, according to Figure 12 The type of handheld shower head is not shown. Accordingly, Figures 1 to 5 The spray disc 13 of the embodiment has a holding device 21 at its respective end. Figures 1 to 5 The holding device 21 of the embodiment is used to hold the device 21 in conjunction with Figures 6 to 12The holding device in the implementation method is configured in the same way.

[0075] In the corresponding implementation, the retaining device 21, as in the example shown, includes a contact surface 22, against which the shower head 19 abuts in the retained state. In this state, the shower head 19 is held in a fixed manner on the retaining device 21, as in... Figure 12 As shown in the diagram. The shower head 19 can then be positioned by pivoting the accessory base 1. If the shower head 19 is to be moved to a position different from the position defined by the retaining device 21, the shower head 19 can be released from the retaining device 21 and moved to any position.

[0076] In an exemplary embodiment, the holding device 21 has a holding body 29 as shown in the example, and a holding magnet 23 as shown in the example. Figure 4 and 9 As can be seen, it is integrated into the retaining body. For example, the retaining magnet 23 can be die-cast into the retaining body 29 during the manufacture of the spray disc 14. The shower head 19 is preferably made of a metal material and is attracted by the retaining magnet 23 and thus held on the abutment surface 22.

[0077] In an advantageous implementation, the retaining device 21, as shown in the illustrated embodiment, has two abutting surfaces 221 and 222. Abutting surface 221 is shaped as a partially cylindrical surface against which the cylindrical shower head 19 abuts with its outer peripheral housing wall in the retained state. Abutting surface 221 is curved and has a radius equivalent to the radius of the cylindrical housing of the shower head 19. Abutting surface 222 is shaped as an annular abutting shoulder against which the lower end of the shower head 19's housing abuts. The cylindrical abutting surface 221 and the annular abutting shoulder 222 are adjacent to each other and oriented perpendicularly to each other. Thus, the position and orientation of the shower head 19 in the retained state, abutting against the two abutting surfaces 221 and 222, are completely defined.

[0078] As clearly demonstrated in the illustrations and other embodiments explained above, the present invention provides a sanitary discharge fitting that offers significant advantages over conventional fittings of this type in terms of the functionality, construction, and installation of the components received within the fitting matrix.
