Description

[0001] The invention relates to a shower head, in particular a sanitary shower head, according to the preamble of claim 1.

[0002] This shower head includes a base body with a shower fluid inlet, a spray disc unit located on a shower jet outlet side of the base body and having several fluid-separated groups of shower jet outlet openings, and several fluid connections from the shower fluid inlet to each of the groups of shower jet outlet openings.

[0003] Showerheads of this type typically serve to deliver a shower fluid with selectable spray patterns, e.g., a massage spray from one group of nozzles and a soft spray from another, and / or with varying fluid volumes, e.g., a smaller volume from only one group of nozzles and a larger volume from several. Such showerheads are particularly common in sanitary applications, for example, as hand showers or overhead showers, where water usually acts as the shower fluid. However, these showerheads are equally suitable for non-sanitary shower applications where any fluid is to be delivered as a spray.

[0004] For shower heads with multiple groups of spray nozzles, it is known to arrange the associated fluid connections on different planes, i.e., one above the other when viewed in the direction of the spray. However, this requires a correspondingly large shower head height and results in a relatively high amount of residual water in the shower head after it is turned off, which in turn can promote undesirable dripping.

[0005] Patent DE 10 2012 213 518 B3 discloses a generic shower head with a shower head housing closed by a spray disc having spray outlet openings, a water inlet into the shower head housing and three separate water channels in the shower head housing, each leading to one of three groups of spray outlet openings in the spray disc, wherein a seal is arranged between each pair of spray outlet openings, which at least temporarily closes an opening between the groups of spray outlet openings and thus seals the groups of spray outlet openings against each other, wherein one group is arranged centrally and the other two groups coaxially surround this central group in a ring shape.Separated by a partition wall, a second water channel, designed as an approximate ring channel, extends around the end of a first water channel, and separated by another partition wall, the second water channel is surrounded by a third water channel, also designed as a ring channel.

[0006] German patent application EP 2 537 592 A1 discloses a shower head as part of a sanitary fitting, consisting of an upper shell and a lower shell with openings for the water to be distributed via the shower head. Inside the shower head, a water-guiding mat made of a sealing elastomer is inserted, with an arrangement of water channels formed in its surface and connected to a central water inlet. Outlet openings are formed in the base of the mat, aligned with the corresponding openings in the lower shell. A single water channel runs from the central water inlet to each outlet opening without any connection to water channels leading to other outlet openings. The upper shell rests on the water-guiding mat with a flat contact surface, and the water channels formed in the water-guiding mat seal tightly at its open surface.

[0007] Patent application US 5,246,301 A discloses a shower head with a shower fluid inlet and a spray disc unit with two fluid-separated groups of shower jet outlets. In the base body of the shower head, a cavity is divided by an internal intermediate floor into two separate fluid chambers, one above the other in the direction of the jet outlet, each chamber corresponding to one of the groups of shower jet outlets.

[0008] The invention is based on the technical problem of providing a shower of the type mentioned above, which offers advantages over the prior art in particular with regard to its shower spray delivery functionality or spray performance and / or its construction with relatively few components, relatively low manufacturing costs, a compact, slim design, low drip time and low water consumption.

[0009] The invention solves this problem by providing a shower head with the features of claim 1. Advantageous embodiments of the invention are specified in the dependent claims, the wording of which is hereby incorporated into the description by reference. This includes, in particular, all embodiments of the invention resulting from the combinations of features defined by the cross-references in the dependent claims.

[0010] In the shower head according to the invention, a cavity is formed in the base body, bounded by a chamber floor and a chamber ceiling. This cavity is divided into several laterally separated fluid chambers by a fluid-tight partition structure between the chamber floor and the chamber ceiling. A first fluid chamber is part of a first fluid connection from the shower fluid inlet to a first group of shower jet outlets, and a second fluid chamber is part of a second fluid connection from the shower fluid inlet to a second group of shower jet outlets. Thus, the first group of shower jet outlets is in fluid communication with the first fluid chamber, and the second group of shower jet outlets is in fluid communication with the second fluid chamber.Furthermore, the first fluid chamber has one or more first main channels extending from an inlet into the first fluid chamber and at least two adjacent first branch channels extending from the one or from at least one of the several first main channels, wherein the two adjacent first branch channels or two adjacent areas of the first fluid chamber supplied by two of the first main channels are arranged laterally apart from each other by an intermediate area of ​​the second fluid chamber.

[0011] This configuration, with its specific arrangement of main and branch channels, offers several advantages regarding the shower head's design and construction, as well as its spray pattern functionality. This particular arrangement allows for a low-profile shower head, which can be desirable for aesthetic reasons. As a further advantage, it minimizes residual water in the body after the shower head is turned off, thus reducing dripping time. The reduced number of components makes the shower head simple and cost-effective to manufacture. Furthermore, it is possible, for example, to supply one of the two groups of spray nozzles with hot water and the other with cold water.By arranging the aforementioned adjacent first branch channels laterally separated from one another by an intermediate section of the second fluid chamber, the prerequisite is very advantageously created for being able to arrange at least two of the groups of shower jet outlets distributed and nested within one another over at least a portion of the entire extent of the spray disc unit. The latter enables, if required, a correspondingly uniform distribution of the shower fluid over the respective outlet surface of the spray disc unit via each of at least two of the several groups of shower jet outlets, in particular via both a first and a different second group of shower jet outlets.

[0012] In one advantageous embodiment, the first fluid chamber has a first main channel extending from the inlet to the first fluid chamber and at least two adjacent first branch channels extending from the main channel, wherein the two adjacent first branch channels are arranged laterally apart from each other by an intermediate region of the second fluid chamber. In another advantageous embodiment, the first fluid chamber has several first main channels extending from the inlet to the first fluid chamber and at least two adjacent first branch channels extending from at least one of the several first main channels, wherein the two adjacent first branch channels or two adjacent regions of the first fluid chamber supplied by two of the first main channels are arranged laterally apart from each other by an intermediate region of the second fluid chamber.

[0013] In a functionally and structurally advantageous embodiment, at least two adjacent first branch channels run on at least two parallel lines offset from each other, e.g., two radially offset lines closed in a circumferential direction of the jet disc unit with a circular, oval, polygonal or other course.

[0014] In certain configurations, the spray disc unit can have more than two fluid-separated groups of shower jet outlets, for example, three or four, each with fluid connections from the shower fluid inlet to its corresponding shower jet outlet. Accordingly, in this case, the cavity can be divided by the partition structure between the chamber floor and the chamber ceiling into more than two, for example, three or four, laterally separated fluid chambers.

[0015] The multiple fluid chambers are preferably located in a common plane that is essentially parallel to the chamber ceiling, which facilitates the achievement of a very flat design for the shower head.

[0016] The groups of shower spray outlets can, in corresponding versions, have different spray patterns of any conventional type, size, and / or shape. The shower head is designed as a sanitary shower head in certain versions, but can be equally suitable for non-sanitary shower applications where any fluid is to be dispensed as a spray.

[0017] In a further development of the invention, the chamber floor has a rigid projection structure on its side facing the chamber ceiling, which interacts with the chamber ceiling to form the partition structure. This represents a structurally and functionally advantageous realization of a fluid-tight separation of the cavity in the base body into several laterally separated fluid chambers. The projection structure has a chamber-forming function, is preferably designed essentially vertically to the chamber floor, abuts the chamber ceiling in a fluid-tight manner, and forms the partition structure. In an alternative embodiment, the chamber ceiling has a rigid projection structure on its side facing the chamber floor, which interacts with the chamber floor to form the partition structure.In another alternative embodiment, both the chamber floor on its side facing the chamber ceiling and the chamber ceiling on its side facing the chamber floor each have a rigid projection structure, with the two projection structures forming the partition structure. In corresponding embodiments, the projection structure is formed integrally on the chamber floor and / or the chamber ceiling, depending on the specific design. The chamber floor and the chamber ceiling are preferably formed on separate components that are detachably connected to each other during assembly of the shower head.

[0018] In a further development of the invention, a rigid insert structure is arranged in the base body between the chamber floor and the chamber ceiling. This insert structure interacts with the chamber floor and the chamber ceiling to form the partition wall structure. The insert structure serves a chamber-forming function, is preferably designed essentially vertically to the chamber floor and the chamber ceiling, and is fluid-tight against both the chamber floor and the chamber ceiling, thus forming the partition wall structure. The insert structure is a separate component, independent of the chamber ceiling and the chamber floor, and is inserted between them. Therefore, its material can be selected independently of these components.

[0019] In a further development of the invention, the second fluid chamber has one or more second main channels extending from an inlet into the second fluid chamber and at least two adjacent second branch channels extending from one or at least one of the several second main channels, all of which branch off from a common second main channel. At least two of the first branch channels and at least one of the second branch channels are arranged nested within each other. Nested arrangement means that the at least one of the second branch channels, along its longitudinal extent, abuts or borders each of the at least two first branch channels with its two longitudinal sides, i.e., is adjacent, unless it is a branch channel located at the edge of the branch channel arrangement, in which case it only borders another branch channel.This achieves an advantageous, comparatively homogeneous spray performance, as both the first and second spray nozzles can be evenly distributed within the spray disc unit, or at least over a portion thereof. This advantageous measure also allows for a relatively large wetting area with minimal water consumption for both the group of first and second spray nozzles.

[0020] The first and second spray nozzle openings can, for example, be arranged in a checkerboard pattern, at least in a partial area, particularly in a central area, of the spray disc unit. In this case, the first and second spray nozzle openings are thus positioned alternately next to each other in both a row direction (also referred to here as the horizontal direction) and in a column direction perpendicular to it (also referred to here as the vertical direction). The column direction (vertical direction) and the row direction (horizontal direction) are understood here to be two mutually perpendicular directions in the plane of the spray disc unit in which the two-dimensional arrangement of the spray nozzle openings lies. Specifically, the column direction (vertical direction) can, for example, be a direction parallel to a longitudinal section of the shower head, in which, if necessary,The shower handle runs parallel to the horizontal direction, while the linear direction (or horizontal direction) runs perpendicular to this longitudinal section plane. It follows that along the corresponding diagonals, only the first or second shower spray outlets are arranged consecutively.

[0021] In one embodiment of the invention, all or at least some of the branch channels leading from the respective main channel are designed as dead-end channels. This represents an advantageous implementation for a homogeneous distribution of the spray nozzle openings and thus for achieving a relatively homogeneous spray performance for different spray patterns. In corresponding embodiments, the spray nozzle openings are arranged along one or more main channels and the branch channels. In alternative embodiments, the spray nozzle openings are arranged only along the branch channels. In corresponding embodiments, the distribution channel structures of the fluid chambers each have at least three, preferably at least ten, dead-end channels.

[0022] In one embodiment of the invention, the first main channel and / or the second main channel is annular, and the branch channels extend inwards or outwards from the respective main channel. This provides advantageous realizations for a relatively homogeneous distribution of the shower spray outlet openings. Specifically, the branch channels extending from the first main channel can, for example, extend inwards and outwards. The first main channel and / or the second main channel preferably extend in an annular or circular manner. In alternative embodiments, the first and / or the second main channel runs along one or more polygonal lines. In corresponding realizations, the first main channel and / or the second main channel each lie on a radius line of the spray disc unit, and the branch channels extend from this in an arc.The first and second main channels can, for example, lie on a common axis, i.e., on a common diameter line of the jet disc unit. In appropriate configurations, the branch channels each extend from their respective main channel in a circular arc, i.e., along segments of circular arcs with a center point in the middle of the jet disc unit, with the ends of each branch channel abutting the other main channel.

[0023] In a further development of the invention, at least some of the first and second shower spray outlets are arranged alternately in the circumferential direction on one or more concentric circles, ovals, or polygons. Preferably, on each of the multiple circles, ovals, or polygons, first and second shower spray outlets are arranged alternately next to each other, so that on the respective line, shower spray outlets of a group are not directly adjacent to one another. This represents an advantageous realization for a homogeneous distribution of the shower spray outlets for the different spray patterns. In alternative embodiments, the first and second shower spray outlets can be arranged alternately, for example, along straight lines, such as in a row, column, or diagonal direction.

[0024] In a further development of the invention, the chamber floor is formed as a rigid plate made of a rigid material, and the chamber ceiling is formed as an elastomeric plate, wherein the chamber floor has the rigid projection structure on its side facing the chamber ceiling. This creates an advantageous fluid-tight partition structure between the chamber floor and the chamber ceiling, in which the rigid projection structure provides the necessary strength and pressure stability, and the elastomeric plate provides the necessary sealing. In alternative embodiments, the chamber ceiling is formed as a rigid plate made of a rigid material, and the chamber floor is formed as an elastomeric plate, with the rigid projection structure in this case also being formed on the side facing the chamber floor.

[0025] In one embodiment of the invention, the chamber ceiling has a sealing structure on its side facing the chamber floor that corresponds to its rigid projection structure and abuts the rigid projection structure in a fluid-tight manner. This represents an advantageous implementation for the fluid-tight partition structure for separating the cavity into the multiple fluid chambers. The sealing structure can, for example, be formed in the form of a raised portion on the chamber ceiling against which the projection structure abuts. Alternatively, in corresponding embodiments, the sealing structure can be formed in the form of a groove in the chamber ceiling in which the projection structure abuts or engages in a form-fitting manner.

[0026] In one embodiment of the invention, the jet disc unit comprises an outer jet disc plate with through-openings and the chamber ceiling. The chamber ceiling rests against an inner surface of the outer jet disc plate and has jet outlet nipples that form the first and second shower jet outlet openings and extend into or through the through-openings. This represents an advantageous implementation for the jet disc unit. The chamber ceiling is arranged between the chamber floor and the outer jet disc plate, in particular in a form-fitting manner, with the chamber floor preferably being connected to the jet disc plate, in particular detachably, whereby the chamber ceiling can be held, for example, clamped between the chamber floor and the jet disc plate.

[0027] In a further development of the invention, the shower head has a valve with a valve closing element, wherein the valve closing element is movably arranged in the base body between at least a first and a second setting position and is configured for selectively shutting off and opening the first and / or the second fluid connection. In an alternative embodiment, the valve is arranged or installed outside the shower head.

[0028] In one embodiment of the invention, the valve closing element, in the first setting position, opens one of the fluid connections and closes a second. In the second setting position, it closes the first fluid connection and opens the second. This represents a functionally reliable and easily manufactured implementation for the valve as a corresponding changeover valve. In an alternative embodiment, the valve closing element, in a corresponding setting position, opens or closes both fluid connections simultaneously. In corresponding embodiments, the valve closing element, in the first setting position, opens only one of the two fluid connections and, in the second setting position, opens both fluid connections simultaneously. In this case, the valve closing element can, for example, close both fluid connections in a third setting position.

[0029] In a further embodiment of the invention, the shower head is a hand shower. In alternative embodiments, the shower head is an overhead shower or a side shower, e.g., one for a sanitary shower unit. In an alternative embodiment, the shower head is a kitchen shower head.

[0030] Advantageous embodiments of the invention are illustrated in the drawings and described below. These and further embodiments of the invention are described in more detail below. The drawings show: Fig. 1 a top view from below of a first embodiment of a shower according to the invention in the form of a hand shower with a base body, a spray disc unit, several fluid connections and a valve, Fig. 2 a sectional view along a line II-II of Fig. 1 , Fig. 3 a perspective exploded view of the jet disc unit and valve of the hand shower of Fig. 1From below, Fig. 4: a perspective exploded view of the spray disc unit and the valve of the hand shower; from above, Fig. 5: a sectional view along a line VV of Fig. 2 Fig. 6 a schematic top view from below of a chamber floor of a round jet disc unit for a second embodiment of a shower according to the invention, which can be configured, for example, as a head shower; Fig. 7 a schematic sectional view along a line VII-VII of Fig. 6 , wherein the jet disc unit comprises a chamber floor, a chamber ceiling and an outer jet disc plate, Fig. 8 a schematic sectional view according to Fig. 7, wherein a rigid insert structure is arranged to form a partition structure between the chamber floor and the chamber ceiling, Fig. 9 a schematic sectional view of a square jet disc unit for a third embodiment of a shower according to the invention, Fig. 10 a schematic top view from below of a chamber floor of a round jet disc unit for a fourth embodiment of a shower according to the invention, and Fig. 11 a schematic top view from below of a chamber floor of a round jet disc unit for a fifth embodiment of a shower according to the invention.

[0031] As from the Figures 1 to 11As can be seen from the exemplary descriptions, the shower head according to the invention comprises a base body 1 with a shower fluid inlet 2 and a spray disc unit 3, which is located on a shower jet outlet side 4 of the base body 1. The shower head further comprises two fluid-separated groups of shower jet outlet openings 5, 6, and a first and a second fluid connection 7, 8 from the shower fluid inlet 2 to each of the groups of shower jet outlet openings 5, 6.

[0032] In the example shown, the Figs. 1 to 5This is a hand shower, suitable for sanitary applications, for example, and includes a valve 11. The valve 11 has a valve closing element 12, which is movably arranged in the base body 1 between at least a first setting position and a second setting position and is configured to selectively shut off and open the first fluid connection 7 and the second fluid connection 8. In the example shown, the valve 11 is configured as a diverter valve that can be actuated by a push button, whereby a switching device of the valve 11, of a type known per se, moves the valve closing element 12 into the defined setting positions.

[0033] In advantageous embodiments, the valve closing element 12, in the first setting position, opens the first fluid connection 7 and closes the second fluid connection 8. In the second setting position, the valve closing element 12 closes the first fluid connection 7 and opens the second fluid connection 8.

[0034] In alternative embodiments, the valve closing element 12 simultaneously opens or closes both fluid connections 7, 8 in a corresponding setting position. In corresponding embodiments, the valve closing element opens only one of the two fluid connections 7, 8 in a first setting position and opens both fluid connections 7, 8 simultaneously in a second setting position.

[0035] In alternative embodiments not shown, the valve 11 is arranged outside the shower head. In this case, the shower fluid inlet 2 is formed from several separate fluid lines.

[0036] In the shower head according to the invention, a cavity 9 is formed in the base body 1, bounded by a chamber floor 16 and a chamber ceiling 18, as shown in particular in the Fig. 2 and 5The cavity 9 is divided into several laterally separated fluid chambers 19, 20 by a fluid-tight partition structure 23 between the chamber floor 16 and the chamber ceiling 18. A first fluid chamber 19 is part of the first fluid connection 7, and a second fluid chamber 20 is part of the second fluid connection 8. Consequently, the first group of shower jet outlets 5 is in fluid communication with the first fluid chamber 19, and the second group of shower jet outlets 6 is in fluid communication with the second fluid chamber 20, as shown in the Fig. 5The first fluid chamber 19 has a first main channel 15 and first branch channels 14 extending from an inlet 13 into the first fluid chamber 19, specifically at least two adjacent first branch channels 141, 142 extending from the first main channel 15, which are arranged laterally spaced apart from each other by an intermediate region B2 of the second fluid chamber 20, as also shown in Fig. 5 This is evident, for example, in the second version ( Fig. 6 ), the third version ( Fig. 9 ) and the fourth version ( Fig. 10) of the shower head according to the invention. In the first branch channels 14, the shower jet outlet openings 5 ​​are preferably arranged in a row one after the other according to the fluid flow in the branch channel 14, i.e., the shower jet outlet openings 5 ​​are approached one after the other along a common fluid flow line in the branch channel 14, as is the case, for example, with a series connection.

[0037] In the fifth embodiment of the shower head according to the invention Fig. 11The first fluid chamber 19 has several first main channels 15 1 , 15 2 leading from an inlet 13 into the first fluid chamber 19 and at least two adjacent first branch channels 14 leading from at least one of the several first main channels 15 1 , 15 2, wherein two adjacent areas B11, B12 of the first fluid chamber 19 supplied by two of the first main channels 15 1 , 15 2 are arranged laterally apart from each other by an intermediate area B2 of the second fluid chamber 20.

[0038] In the version shown according to Fig. 10The jet disc unit 3 has more than two fluid-separated groups of shower jet outlet openings 5, 6 and more than two fluid connections 7, 8 from the shower fluid inlet 2 to each of the groups of shower jet outlet openings 5, 6. In this embodiment, the cavity 9 is thus divided by the partition structure 23 between the chamber floor 16 and the chamber ceiling 18 into more than two, in this case six, separate fluid chambers 19, 20, 35, 36, 37, 38. The inlets of the fluid chambers 35, 36, 37, 38 are designed analogously to the inlets 13, 34 of the fluid chambers 19, 20, but for the sake of clarity are shown in the Fig. 10not marked with a reference symbol. Alternatively, several of the fluid chambers 19, 20, 35, 36, 37, 38 are connected to each other, for example, fluid chambers 19, 35, 37 on one side and fluid chambers 20, 36, 38 on the other. To connect the fluid chambers 19, 20, 35, 36, 37, 38, the respective inlets into these fluid chambers 19, 20, 35, 36, 37, 38 open into each other upstream.

[0039] In corresponding versions, such as according to the Figs. 1 to 7 and 9 until 11 , the chamber floor 16 has a rigid projection structure 22 on its side facing the chamber ceiling 18, which interacts with the chamber ceiling 18 to form the partition structure 23, as shown in particular in the Fig. 2 and 3The projection structure 22 is, in the illustrated embodiments, essentially vertical, i.e., perpendicular, to the chamber floor 16, lies fluid-tight against the chamber ceiling 18, and forms the partition structure 23. In the present case, the chamber ceiling 18 is designed as a blasting mat, which is preferably made of silicone or a comparable elastomeric material.

[0040] In versions such as the one according to Fig. 8In the base body 1, a rigid insert structure 33 is arranged between the chamber floor 16 and the chamber ceiling 18. This insert structure interacts with the chamber floor 16 and the chamber ceiling 18 to form the partition wall structure 23. The insert structure 33 has a chamber-forming function, is essentially vertical to the chamber floor 16 and the chamber ceiling 18, and is fluid-tight against both the chamber floor 16 and the chamber ceiling 18, forming the partition wall structure 23. As in the example shown, the insert structure 33 can be formed as a plate with recesses to form the cavity 9. Alternatively, however, differently shaped insert structures are also conceivable, in particular with a thin-walled partition wall structure.

[0041] In one embodiment (not shown), the chamber ceiling 18 has a rigid projection structure 22 on its side facing the chamber floor 16, which interacts with the chamber floor 16 to form the partition structure 23. In alternative embodiments, both the chamber floor 16 and the chamber ceiling 18 can each have a rigid projection structure 22 on their side facing the chamber floor 16, which together form the partition structure 23.

[0042] At the in Figs. 1 to 5 the version shown, which in Fig. 6 and 9 until 11 In the illustrated embodiments and other corresponding embodiments, the projection structure 22 is formed in one piece on the chamber floor 16. Furthermore, in advantageous embodiments, such as in the examples shown, the chamber floor 16 and the chamber ceiling 18 are formed on separate components, as is particularly evident in the Figs. 3 and 4 shown.

[0043] In corresponding embodiments, the first and second shower jet outlet openings 5, 6 are arranged in a checkerboard pattern in a partial area, in this case in a central area, of the jet disc unit 3, as shown in the example of the Figs. 1 to 5 This is the case, and especially in the Fig. 1 This is evident. In other words, in the central area of ​​the spray disc unit 3, the first shower jet outlets 5 and the second shower jet outlets 6 are arranged alternately next to each other in both a row direction ZR (horizontal direction) and a column direction SR (vertical direction), while along the corresponding diagonals, only the first or second shower jet outlets 5, 6 are arranged consecutively. The column direction SR (vertical direction) runs parallel to a longitudinal section plane E of the shower head, as shown in Fig. 1The row direction ZR, or the horizontal direction, is accordingly perpendicular to this longitudinal plane E.

[0044] In advantageous embodiments, the second fluid chamber 20 has one or more second main channels 26, 261, 262 extending from an inlet 34 into the second fluid chamber 20, as shown in the examples, and at least two adjacent second branch channels 25 extending from one or at least one of the several second main channels 26, 261, 262, which branch off from a common second main channel 26, 261, 262. Furthermore, in advantageous embodiments, as in the examples shown, at least two of the first branch channels 14 and at least one of the second branch channels 25 are arranged nested within each other. The at least one of the second branch channels 25 is bordered, as shown in the Figs. 1 to 10As shown, along its longitudinal extent, at least in sections, the two long sides connect to one of at least two of the first branch channels 14. At least two of the first branch channels 14, 14 1 , 14 2 and at least one of the second branch channels 25 thus interlock in a comb-like manner.

[0045] In the explanations according to the Figs. 1 to 10 The second fluid chamber 20 has a second main channel 26 and at least two adjacent second branch channels 25 leading from the first main channel 26. In the embodiment according to the Fig. 11 The second fluid chamber 20 has several second main channels 26, 26 1 , 26 2 and at least two adjacent second branch channels 25 branching off from at least one of the several second main channels 26, 26 1 , 26 2.

[0046] In advantageous embodiments, as in the examples shown, the branch channels 14, 25 leading from the respective main channel 15, 26 are designed as dead-end channels. In the embodiments according to the Figs. 1 to 5 and 9 The shower jet outlet openings 5, 6 are arranged along the main channels 15, 26 and the branch channels 14, 25.

[0047] In an alternative embodiment, the shower jet outlet openings 5, 6 are arranged only along the branch channels 14, 25, as in the embodiments according to the Fig. 6 , 10 and 11 has been realized.

[0048] In advantageous realizations, as in the corresponding examples shown, the first main channel 15 and / or the second main channel 26 runs in a ring shape and the branch channels 14, 25 leading from it run inwards or outwards from the associated main channel 15, 26.

[0049] In the according to Fig. 5In the illustrated embodiment, the first main channel 15 is annular, and the branch channels 14 extending from it run inwards and outwards. The second main channel 26 is located in a central area of ​​the jet disc unit 3, and the branch channels 25 extending from it run outwards in the direction of the first main channel 15.

[0050] In advantageous alternative embodiments, the first main channel 15 and the second main channel 26 each lie on a radius line R of the jet disk unit 3, as shown in the examples of Fig. 6 and 11 This is implemented. The first main channel 15 and the second main channel 26 are located in the examples according to... Fig. 6 and 11on a common axis. The branch channels 14, 25 extend in corresponding configurations, as in the examples shown, from the respective main channel 15, 26 in a circular arc, i.e. along circular arc line segments with a circle center in the middle of the jet disc unit 3, and their ends adjoin the other main channel 15, 26.

[0051] In corresponding implementations, at least part of the first and second shower jet outlet openings 5, 6 are located, as in the example of the Fig. 6 , alternating circumferentially on one or more concentric circular lines K, as in the Fig. 6 is shown.
