EP2988876B1 - Shower head with rotatable control disk - Google Patents

Description

The invention relates to a shower head comprising a jet disc with inlet openings and outlet openings on opposite sides of the disc and each with a passage for connecting each outlet opening with at least one inlet opening and a control disc which is rotatably arranged in the fluid flow direction in front of the jet disk relative to this and a Control slot pattern for releasing the inlet openings depending on the rotational position of the control disk has.

Such shower heads are used for example in the sanitary area for hand and overhead showers of shower and bath systems. The use of the control disk, which is rotatable relative to the jet disk, allows the effervescent spray characteristic, i. the jet outlet characteristic of the shower head, variable in time, which is e.g. can be used to achieve a massage effect.

A shower head of this type is in the patent EP 0 900 597 B1 disclosed. When local shower head acts as a jet disc provided with a turbine blade structure rotor having a closure element which extends in the circumferential direction over about half the circumferential length. The jet disk is provided with passage channels which are circular in cross-section and which are successively released or blocked by the closure element upon rotation of the fluid-driven rotor, wherein the closure element blocks or releases approximately half of the through-channels.

In a similar shower head, as in the published patent application US 2010/0127096 A1 is disclosed, the closure element is formed in corresponding embodiments as a slotted disc with arcuate passage slots, which at different radii and in the circumferential direction offset from each other are arranged to each release or shut off a corresponding part of lying on the respective radius beam outlet openings in the jet disk.

One in the published patent application DE 10 2008 015 969 A1 disclosed shower head has at least two separate water-carrying chambers in a housing, which are each connected to a group of jet outlet openings of a jet disk. Between an inlet and the chambers, a valve device is provided, which is cyclically actuated by means of a drive and designed to open and close the chambers. For this purpose, the valve device can have an intermediate bottom, which together with the jet disk delimits the chambers and contains feed openings to the chambers, and a rotating control disk in order to respectively open and shut off one of the two supply openings and thus supplied water either only into one or the other let other chamber through.

In addition, various showerheads have already been proposed, the time variation of the shower spray characteristic are provided with movable jet outlet elements, which are mounted rotatably and / or pivotally mounted on a jet disk body, see for example the published patent applications DE 10 2008 015 970 A1 . WO 00/10720 A1 and US 2006/0032945 A1 as well as the patent DE 10 2011 013 534 B3 , Such showerheads require a corresponding number of movably mounted in the jet disk body beam outlet elements and a relatively complex drive for these movable jet outlet elements.

The invention is based on the technical problem of providing a shower head of the type mentioned, which allows an advantageous change over time of the shower spray characteristic with relatively little effort.

The invention solves this problem by providing a shower head with the features of claim 1. In this shower head the Steuerschlitzmuster and the inlet openings of the jet disc are coordinated so that when rotating the control disc two adjacent inlet openings, with a common outlet opening via two through channels non-parallel side walls to provide two different beam exit directions correspond, or two areas of an inlet opening, which corresponds to an outlet opening via a passage with non-parallel side wall areas to provide two different beam exit directions, or two adjacent inlet openings, which correspond to two adjacent outlet openings, alternately released become.

These upon rotation of the control disk alternating and successive release and blocking of belonging to a common outlet opening inlet openings or inlet opening areas or belonging to two preferably closely adjacent outlet openings inlet openings provides the spray head according to the invention for the desired temporal change of the beam characteristic, without the need for elaborate, rotatably mounted on the jet disk body beam exit elements must be provided. The shower head according to the invention therefore comes with comparatively few individual parts and with comparatively few moving parts. The variability of the jet pattern is not achieved by a plurality of movable jet outlet elements or jet nozzles, but by a periodically alternating blocking and releasing of adjacent inlet openings or inlet areas of the jet disk, which correspond to a common or two closely spaced outlet openings. As a result, depending on whether it passes through one or the other inlet opening or the one or the other inlet opening region into the jet disk, the fluid can emerge from the jet disk with a different outlet characteristic and / or at an offset point. During operation of the shower head, different jet images of the fluid jet emerging from the shower head alternate periodically with continuous rotation of the control disk, the different jet images being generated per complete rotation of the control disk by alternately releasing and blocking the various inlet openings or inlet opening areas by means of the control slot pattern.

In a development of the invention, the adjacent inlet openings or inlet opening areas are arranged at different radii of the jet disk, and the control slot pattern includes slot areas arranged correspondingly at different radii. This represents a structurally advantageous implementation of the desired functionality, that the adjacent inlet openings or inlet opening areas are alternately released and shut off upon rotation of the control disk. In an embodiment of this measure, the control slot pattern includes separate, on different Radial arranged slot segments, which are each assigned to one / one of the two adjacent inlet openings or inlet opening areas, and / or at least one in the circumferential and radial direction of the control disc extending slot, the two adjacent inlet openings and inlet opening areas is assigned. In a further embodiment of this measure, the control slot pattern includes a slot which is continuous in the circumferential direction and is bridged with at least one bridge web and / or slots which extend in the circumferential direction and are separated from one another by one or more separating webs. The term separating web here is to be understood as meaning a relatively narrow web which interrupts the slot and thereby connects a radially inner and a radially outer control disk region. Preferably, the width of the divider is at most about as large as the width of the slot.

In one development of the invention, at least one of the through-channels in a jet disk radial plane has a cross-section which tapers conically towards the outlet opening. Such a through-channel can assign an outlet opening, which extends in the radial direction, to an outlet opening, whose radially inner area and its radially outer area can function as the areas of an inlet opening located at different radii.

In a development of the invention, the control disk is driven like a turbine by the fluid flow. For this purpose, it can be provided on its side facing away from the jet disk with a corresponding turbine blade structure. Alternatively, the control disk can be coupled via a gear with a fluid-powered turbine wheel, which is arranged with the gear on the jet disc side facing away from the control disk. In a further embodiment, the slot pattern of the control disk can be arranged radially outside of the turbine wheel and the transmission, so that the jet control by the control disk can be kept unaffected by the transmission and the turbine wheel. In another embodiment, the transmission is a planetary gear with a sun gear provided on the turbine wheel, an outer ring gear provided on the control disk and at least one intermediate planet gear. Such a transmission can provide a structurally simple way for a desired reduction of the turbine wheel rotational movement.

In a further development of the invention, the shower head comprises a manually operable blocking mechanism for blocking the control disk rotational movement in a first blocking position, in which one of the two adjacent inlet openings or inlet opening areas is released, and / or a second blocking position, in which the / the other the two adjacent inlet openings or inlet opening areas is released. With the blocking mechanism, it is possible for a user to selectively stop the control disk rotation during operation, thereby maintaining a jet pattern associated with the corresponding blocking position of the control disk.

In one embodiment of this measure, the blocking mechanism comprises a hand-operable blocking pin which is movably held on the jet disk and can be successively switched between at least three different positions, one of which releases the rotational movement of the control disk and the other two releases the control disk in its first and second blocking positions hold. For this purpose, the blocking pin can be brought, for example by a rotational movement and / or axial movement in the different positions and provided with a plurality of circumferentially and / or radially offset from each other arranged blocking stops, which cooperate with corresponding counter-attacks on the control disc or on the turbine blade structure.

One in the Fig. 1 to 5 as a first embodiment of the invention shown shower head includes a cup-shaped showerhead housing 1, a control disc 2 received therein with integrally formed on an inner side 2a turbine blade structure 3 and a jet disk 4, which rests with an inlet side 4a against the outside of the control disk 2. The jet disk 4 is rigidly connected to the housing 1, and the control disk 2 is in contrast rotatably held in the shower head interior formed by the housing 1 and the jet disk 4. For this purpose, a cylindrical bearing extension 5 formed on the inlet or inner side 4a of the jet disk 4 engages in a corresponding central opening 6 of the control disk 2.

The showerhead housing 1 has a lateral, i. circumferential fluid inlet 7 on. The inlet 7 is associated in a manner known per se on the inside of the housing 1 with a flow guiding structure, by means of which the fluid supplied via the inlet 7 is directed onto the turbine blade structure 3 with a peripheral directional component, whereby the control disk 2 is set in rotation. In this way, the supplied fluid flow, in the case of a sanitary shower water flow, used as a drive means by which the control disk 2 is rotated. The turbine blade structure 3 includes a plurality of circumferentially distributed turbine blades which extend in a wedge-shaped manner in the radial direction, so that the fluid supplied via the lateral inlet 7 can be distributed over the entire housing interior.

The jet disk 4 is provided on its inlet side 4a with a plurality of inlet openings 8 and on its outlet side 4b with a plurality of outlet openings 9. This lead, as in particular from the 3 and 4 can be seen, each two radially adjacent inlet openings 8a, 8b via an associated passageway 10a, 10b in a common outlet opening 9. For this purpose, the two passage channels 10a, 10b extend with mutually inclined longitudinal axes through the jet disk 4 from the inlet side 4a to the outlet side 4b. In the example shown, the longitudinal axes of each two of two radially adjacent inlet openings 8a, 8b leading to a common outlet opening 9 through channels 10a, 10b inclined by the same angle relative to a longitudinal axis 11 of the shower head, for example, at an angle between 5 ° and 30 °. Accordingly, the two passage channels 10a, 10b, which lead from two radially adjacent inlet openings 8a, 8b to a common associated outlet opening 9 of the jet disk 4, non-parallel side wall portions 12a, 12b.

The control disk 2 is provided with a control slot pattern 13, wherein the control slot pattern 13 and the inlet openings 8 of the jet disk 4 are coordinated such that when the control disk 2 rotating, the two radially adjacent inlet openings 8a, 8b, which open into a common outlet opening 9, alternately be released. This means that during one complete rotation of the control disk 2, the control slot pattern 13 releases the one of the two adjacent inlet openings 8a, 8b over a certain first angular range and releases the other of the two inlet openings 8a, 8b over a certain second, different angle range from the first while it covers the relevant inlet opening in the remaining angular range, ie closed.

In the exemplary embodiment shown, the jet disk outlet openings 9 are arranged on two different radii, a first group of eight outlet openings 9 on an inner radius and a second group of sixteen outlet openings 9 on an outer radius. Corresponding to this, eight pairs of radially adjacent inlet openings 8a, 8b are arranged on the inlet side 4a of the jet disk 4 in a region lying radially further inwards and sixteen pairs of radially adjacent inlet openings 8a, 8b are arranged in a region lying radially further outside. Consequently, the inlet openings 8 are along a total of four different radii. Correspondingly, the control slot pattern 13 of the control disk 2 has slot regions 13 ₁ , 13 ₂ , 13 ₃ , 13 ₄ arranged on four different radii, which are formed as slot segments. For each of the four radii two slot segments 13 ₁ to 13 _{4 are} provided, each extending over an angular range of 90 ° and are separated by two non-slotted 90 ° segments. In this case, the slot segments 13 ₁ , 13 ₂ and 13 ₃ , 13 ₄ belonging to the paired inlet openings 8 a, 8 b are correspondingly open each adjacent radii are offset by 90 ° to each other, so that one of the two paired inlet openings 8a, 8b always released by the control slot pattern 13 and the other is covered.

In alternative embodiments, an overlap of the slot areas may be provided, so that one of the paired inlet openings 8a, 8b, which open into the same outlet opening 9, one already at least partially released before the other is completely covered. Depending on the design of such an overlap region, a more abrupt or even transition between the correspondingly different shower spray characteristics can be achieved.

Furthermore, in the exemplary embodiment shown, the slot segments 13 ₁ , 13 ₃ , which belong to the innermost and third inner radius and thus respectively to the radially inner inlet openings 8a of the inlet opening pairs 8a, 8b, offset by 45 ° from each other, as in particular Fig. 5 evident. Likewise, the slot patterns 13 ₂ , 13 _{4 of} the second-most and the outermost radius, which correspond to the outer inlet openings 8 b of the inlet opening pairs 8 a, 8 b, are offset by 45 ° from one another.

This in the embodiment of Fig. 1 to 5 Selected vote of Steuerschlitzmuster 13 and inlet openings 8 has the result that the Effervescent Radiation characteristic changes after each rotation of the control disc 2 by 45 °, resulting in a total of four different Effervescent characteristics, each of which occurs twice in a full revolution of the control disc 2. Because due to the non-parallel side wall portions 12a, 12b of the two passageways 10a, 10b, the two radially adjacent inlet openings 8a, 8b connect with an outlet opening 9, results for the guided through the jet disk 4 fluid after exiting the respective outlet opening 9 another beam exit direction Sa, Sb, depending on whether the fluid passes through the one, eg radially inner inlet opening 8a or the other, eg radially outer inlet opening 8b to the respective outlet opening 9. The jet outlet directions Sa, Sb are substantially parallel to the side wall portions 12a, 12b of the through channels 10a, 10b, since these side wall portions 12a, 12b serve as guide surfaces or flow guide surfaces along which the fluid is guided from the inlet side 4a to the outlet side 4b of the jet disk 4 , Each pair of radially adjacent inlet openings 8a, 8b thus provides two possible jet outlet directions Sa, Sb for the associated outlet opening 9.

In the 3 and 4 two different rotational position situations of the control disk 2 are illustrated. In the position of Fig. 3 the control disk 2 with its control slot pattern 13 of the four in this sectional view to be recognized opening pairs, which are along a diameter line of the jet disk 4, respectively the radially inner inlet opening 8a of the two radially inner Eintrittsöffnungspaare and the radially outer inlet opening 8b of the two radially outer Eintrittsöffnungspaare through the slot segments 13 ₁ and 13 ₄ free. This leads to a jet pattern S1, in which the exit jets of the two radially outer outlet openings 9 with radially inwardly directed component and the two radially inner outlet jets exit with radially outwardly directed component. In the position of Fig. 4 gives the control disk 2, the inlet openings complementary to Fig. 3 free, ie the radially outer inlet openings 8b of the two radially inner inlet opening pairs and the radially inner inlet openings 8a of the two radially outer inlet opening pairs are released through the slot segments 13 ₂ and 13 ₃ , the other inlet openings covered. This leads to a spray pattern S2, in which the two radially outer jets emerge with component facing radially outward and the two radially inner jets exit with radially inwardly directed component.

In operation, the fluid, such as water in the case of using the shower head for a sanitary shower via the inlet 7 into the interior of the showerhead housing 1, thereby displaces the control disk 2 due to the turbine blade structure 3 in continuous rotation, passes through the slots of the control slot pattern thirteenth through in the respective released inlet openings 8 of the jet disk 4 and through the passage channels 10a, 10b through to the outlet openings 9 to emerge from there with a Effervescent characteristic which varies in time according to the rotating control disk 2, as explained above. During each full revolution of the control disk 2 results from the specific vote of the control slot pattern 13 and the inlet openings 8 in conjunction with the assignment of two radially adjacent inlet openings 8a, 8b to a common outlet opening 9 via the associated passage channels 10a, 10b with non-parallel side wall portions two different outflow directions Sa, Sb for each outlet opening 9.

In addition, by appropriate dimensioning and arrangement of the various slot segments 13 ₁ to 13 _{4 of} the control slot pattern 13, a desired defined time sequence of the instantaneous beam direction for the various outlet openings 9 can be set with each other, as from the above explanations to the 3 and 4 becomes clear. Overall, there is thus a temporal variation of the shower spray characteristic for the fluid emerging from the shower head via the outlet openings 9, without requiring any movable jet outlet elements for this purpose. Rather, it is sufficient for the jet disk 4 relatively movable arrangement of the control disk 2, which in the illustrated embodiment of Fig. 1 to 5 represents the only movable element of the shower head. Alternatively, if needed Of course, additionally be provided movable beam outlet elements. In further alternative embodiments, the jet disk may form the actively rotated element with the control disk fixed.

The Fig. 6 to 10 illustrate a second shower head according to the invention, which represents a variant of the first shower head, wherein for ease of understanding identical and functionally equivalent elements, the same reference numerals are selected as for the first shower head and in this respect to the above description of the Fig. 1 to 5 can be referenced.

In contrast to the first shower head, two adjacent inlet openings 8a, 8b each correspond to two corresponding adjacent outlet openings 9a, 9b in the second shower head, wherein separate passage channels 14a, 14b are provided for connecting each inlet opening 8a, 8b with their corresponding outlet opening 9a, 9b. The passage channels 14a, 14b extend in this embodiment as rectilinear bores from the respective inlet opening 8a, 8b to the respective outlet opening 9a, 9b through a jet disk 4 'modified so far. Thus correspond in this shower head, the number and arrangement of the outlet openings 9 of those of the inlet openings 8, as well as from the Fig. 6 and 7 to recognize. The control disk 2 corresponds with its integrated turbine blade structure 3 and the control slot pattern 13 that of the first shower head.

The temporal jet image variation results in the shower head of Fig. 6 to 10 in that, when the control disk 2 is rotating, its control slot pattern 13 alternately alternates with the various slot segments 13 ₁ to 13 _4, analogously to the first shower head, the two inlet openings 8 a, 8 b of each pair of radially adjacent inlet openings, ie successively, releases and shuts off, so that thereby the fluid emerges alternately from one and the other of the two corresponding, radially adjacent outlet openings 9a, 9b. The 8 and 9 show longitudinal sections of two snapshots in which for the four pairs of inlet openings shown once and the other time the other inlet opening are released, resulting in correspondingly different jet images S3 and S4.

In other words, in this shower head results in the temporal change of Effervescent characteristics for each pair of radially adjacent inlet openings 8a, 8b in that the fluid jet periodically alternately exits one or the other of the two corresponding adjacent outlet openings 9a, 9b, while the first shower head of the Fig. 1 to 5 the jet image variation is based on a change in the exit direction of the fluid jet emerging from the respective common outlet opening 9. Moreover, the above-mentioned for the first shower head functional properties and advantages apply in the same way for the second shower head.

In the 11 to 18 a third shower head according to the invention is shown, again for ease of understanding the same reference numerals for identical or functionally equivalent elements are used as in the two shower heads of Fig. 1 to 10 , This third shower head differs from the two spray heads explained above substantially by a jet disk 4 "with a modified pattern of the inlet and outlet openings 8, 9 and by the presence of a blocking mechanism for blocking the control disc rotation either in one of two blocking positions, the correspond to different Effervescent Images.

Specifically, the jet disk 4 "has the through channels 10a, 10b with the non-parallel side wall portions of the first shower head Fig. 1 to 5 for connecting each of two radially adjacent inlet openings 8a, 8b with a common outlet opening 9, as can be seen in particular from the Fig. 16 to 18 shows, however, the inlet openings 8 and thus the corresponding outlet openings 9 are not distributed over the entire circumference of the jet disk inlet side 4a in this shower head, but are limited to two opposite sectors, each extending over an angular range of approximately 90 ° , This corresponds to a modified control slot pattern 13 ', which in turn consists of each 90 ° extending slot segments that are modified in their mutual arrangement relative to the Steuerschlitzmuster 13 of the first and second shower head so that the Effervescent when rotating control disk 2 between the two beam images S5, S6 alternates in the FIGS. 17 and 18 are shown.

The above-mentioned blocking mechanism allows the third shower head to block the control disk 2 against further rotation and thus retaining the same optionally in the position of Fig. 17 with the spray pattern S3 or in the position of Fig. 18 with the spray pattern S4 on user's request. Specifically, the blocking mechanism is manually operated as a combined pressure / rotation mechanism, as is known, for example, from ballpoint pens. For this purpose, the blocking mechanism includes a blocking / actuating pin 15 with a suitably profiled pin head 16 which is guided in a recess 17 on the inlet side 4a of the jet disk 4 "and on which a push button 18 acts, from the outside into a recess 19 on the outside the jet disk 4 "inserted and connected to the pin head 16.

The actuating pin 15 extends eccentrically through the central opening 6 of the control disk 2 through and is supported by a coil spring 20 resiliently against the inside of the upper part of the showerhead housing 1 from. For this purpose, the spring 20 on the one hand to a Foot part 21 of the actuating pin 15 and on the other hand held on a bearing projection 22 of the housing inner side. When the user presses on the push button 18, this moves the actuating pin 15 axially forward or in the 11 to 18 upwards against the force of the coil spring 20. The axial movement of the actuating pin 15 causes a rotation of the actuating pin 15 by 90 ° by cooperation of the profiled pin head 16 with a corresponding profile in the head receptacle 17 of the jet disk 4. When releasing the push button 18 presses the coil spring 20 the actuating pin 15 together with the push button 18 back axially back to the starting position, wherein the actuating pin 15 remains in this axial return movement in its achieved by the previous axial forward movement rotational position.

At its periphery of the actuating pin 15 between the head part 16 and foot 21 is provided with two radially projecting blocking stops 23, 24 which are circumferentially offset by approximately 90 ° and in the axial direction by more than their axial extent against each other, so that they are not in Circumferential direction, still overlap in the axial direction.

Corresponding to these blocking stops 23, 24, two of the turbine blades 3 each have a blocking lug 25, 26 extending radially inwards as far as the center opening 6. The remaining turbine blades end at a radial distance in front of the center opening 6, as in FIGS Fig. 11 . 14 and 15 to recognize, or they extend to the center opening 6, as in the extent somewhat modified Fig. 16 to 18 indicated, but only with such a small axial height that they can not come into locking contact with the axially overlying blocking stops 23, 24 of the actuating pin 15. Specifically, a first turbine blade 3a has a lower blocking lug 25 which coincides with the in the 11 to 18 further down, ie closer to the head portion 16 lying blocking stop 23 cooperate. This blocking lug 25 ends axially after above in front of the above, that is closer to the foot part 21 lying blocking stop 24 so that it does not cooperate with this in the sense of blocking the control disk rotation. A second turbine blade 3b has an upper limiting lug 26 which cooperates with the upper limit stop 24 of the actuating pin 15 and ends axially in front of the lower limit stop 23. As a result, the turbine blade 3b interacts on its radially inner side by its upper blocking lug 26 only with the upper blocking stop 24 of the actuating pin 15, while it does not interact with the lower blocking stop 23 regardless of the rotational position of the actuating pin 15.

Like from the Fig. 13 to 18 it can be seen, the actuating pin 15 is arranged with a predetermined transverse offset Q to the longitudinal center of the shower head in the central region of the shower head, ie its longitudinal axis 27 is offset relative to the shower head longitudinal axis 11 by the corresponding dimension Q in parallel. This offset is matched to the radial extension of the blocking stops 23, 24 and the corresponding blocking lugs 25, 26 so that the respective blocking stop 23, 24 with the corresponding locking lug 25, 26 only ever cooperates in the blocking sense when the actuating stop 23, 24th is located on the side remote from the shower head longitudinal center axis 11 diametrically opposite side of the actuating pin 15. In this position, the respective blocking stop 23, 24 bring by the described combined axial / rotational movement.

Fig. 16 shows the actuating pin 15 in a rotational position in which none of its two blocking stops 23, 24 assumes a blocking position on the side remote from the shower head longitudinal center axis 11 side. Consequently, in this position of the blocking pin 15, the control disk 2 with its turbine blade structure 3 rotate freely. The control disk 2 is supported in this case radially outwardly and axially upwards on the housing 1 and axially downwards on the jet disk 4 ", while its center opening 6 serves in this case only for the passage of the actuating pin 15 and not for storage on a central bearing extension of the jet disk Fig. 16 the control disk 2 in operation continuously, and there is the aforementioned change in time of the shower spray characteristic in the form of an alternating change between the beam images S3 and S4 according to the FIGS. 17 and 18 ,

When the user actuates the push button 11 once, starting from this release position of the blocking mechanism, the actuating pin 15 subsequently takes a counter-clockwise 90 ° rotated position as shown in FIG Fig. 17 is shown. In this position, the upper blocking stop 24 is in its side facing away from the shower head longitudinal axis 11 blocking position. This has the consequence that it blocks the rotation of the control disk 2, as soon as the relevant turbine blade 3b with the upper locking lug 26 against this upper blocking stop 24 comes to rest, as in Fig. 17 illustrated. The control disk 2 then remains in this position, so that the fluid now exits the shower head with the fixed spray pattern S3, without changing in time.

When the user then actuates the blocking mechanism again via the push button 18, the actuating pin 15 reaches its in Fig. 18 shown, again rotated by approximately 90 ° in the counterclockwise direction, in which the lower blocking stop 23 occupies its remote from the shower head longitudinal center axis 11 blocking position. In this blocking position, the lower blocking stop 23 cooperates in the blocking sense with the lower blocking nose 25 of the relevant turbine blade 3a. At the same time passes through the further rotation of the actuating pin 15 from its previous blocking position in its release position, the upper blocking stop 24, thereby being blocking interaction with the upper locking lug 26 is released. The control disk 2 thus turns from its blocking position of Fig. 17 out further until the turbine blade 3a comes with its lower blocking lug 25 against the lower blocking stop 23 of the actuating pin 15 to the plant. Thereafter, the rotation of the control disc 2 stops again, and the shower head supplies the other spray pattern S4 of Fig. 18 as permanent shower spray characteristic.

By pressing the push button 18 again, the user can the blocking position of Fig. 18 with the fixed jet pattern S4 cancel. By the pressure actuation effected further rotation of the actuating pin 15 by turn about 90 ° reaches the lower blocking stop 23 in its release position, in which he no longer interacts with the lower locking lug 25 of the turbine blade 3a. On the other hand, the upper limit stop 24 still remains in its release position due to this further rotation of the actuating pin 15, so that the control disk 2 can now rotate freely again. In other words, the user switches from the blocking position by one-time operation of the blocking mechanism Fig. 18 in the release position, in which the freely and continuously rotating control disc for the described alternating change between the jet images S3 and S4 provides.

In the Fig. 19 to 28 a fourth shower head according to the invention is illustrated, which except for a variant of the blocking mechanism of the third shower head according to the invention 11 to 18 corresponds, in turn, the same reference numerals are used for identical and functionally equivalent elements and to that extent can be made to the above description of the first to third shower head.

When shower head the Fig. 19 to 28 The blocking mechanism for blocking the control disc rotation includes a blocking / actuating pin 28, which is circumferentially rotatably mounted in a peripheral through-hole 33 of a so far relative to the jet disk 4 "of the third shower head modified jet disk 4 _1. For this purpose, the jet disk 4 _{1 has} a bulge 33 a at its periphery, in the area of the feedthrough bore 33 is and against which a knurled head 29 of the actuating pin 28 abuts on its axial outer side, with which a user can turn the actuating pin 28. For this purpose, the knurled head 29 protrudes radially somewhat beyond the circumference of the shower head housing 1 and the jet disk 4 ₁ .

The actuating pin 28 protrudes with a foot part 28a into a side wall region of the housing 1, for which purpose the housing side wall has a matching recess 32, in which the foot part 28a of the actuating pin 28 is accommodated. At its foot portion 28a of the actuating pin 28 is similar to the actuating pin 15 of the third shower head with two circumferentially radially projecting blocking stops 30, 31 are provided, which are arranged in the circumferential direction by 90 ° and in the axial direction one behind the other. The recess 32 on the side wall of the housing 1 is sized so that the blocking stops 30, 31 of the actuating pin 28 can rotate freely therein when the actuating pin 28 is rotated.

The blocking function is realized in this fourth shower head, that each of the two blocking stops 30, 31 of the actuating pin cooperating blocking the radially outer side of each one of the turbine blades of a so far modified turbine blade structure 3 'of the control disk 2. Specifically, a turbine blade 3'a cooperates with the axially-facing, upper-block stop 31 in the figures when it is in a radially inward-pointing position, and a turbine blade 3'b acts with the knurled head lower in the figures 29 closer blocking stop 30 together, when this is in its radially inwardly pointing position.

For this purpose, all other turbine blades 3 'are provided on their radially outer side with a first, wider recess 34, which is dimensioned such that the turbine blades 3' provided with this recess 34 freely rotate past it in any position of the actuating pin 28, even if one of its blocking stops 30, 31 is in the radially inwardly facing blocking position. The blocking stop 30, 31 in each case passes through the recess 34, which extends axially at least over the entire axial length of both blocking stops 30, 31. In contrast, the turbine blade 3 'a on its radial outer side on a narrower, lower recess 34 a, which is dimensioned so that although the lower blocking stopper 30 can pass through this recess 34 a, when it is in its radially inwardly facing blocking position, not However, the upper blocking stop 31. Similarly, the turbine blade 3'b is provided with an upper, narrower recess 34b, which is dimensioned so that, although the upper blocking stop 31 of the actuating pin 28 can pass when it is in its radially inwardly facing blocking position but not the lower blocking stop 30.

This design results in the following operation of this blocking mechanism. In a release position, as in the FIGS. 23 and 24 is illustrated, the actuating pin 28 is in a rotational position in which none of its two blocking stops 30, 31 occupies its radially inwardly facing blocking position, but both blocking stops 30, 31 are within the recess 32 of the housing side wall, without radially from the housing side wall to project in. As a result, the turbine blade structure 3 'and with it the control disk 2 can rotate completely unhindered, which results has that results in the above-described temporal variation of the shower spray characteristic in this mode of the shower head.

On the basis of this, if the user wishes to permanently maintain one of the various spray jet characteristics during operation of the shower head, he can turn the actuating pin 28 on his knurled head 29 into a corresponding blocking position. The Fig. 25 and 26 illustrate a blocking position in which the turbine blade 3'a blocking cooperates with the radially inwardly facing upper blocking stopper 31. For this purpose, the user turns the actuating pin 28 by 90 ° clockwise from the in the FIGS. 23 and 24 shown release position out. While all the other turbine blades 3 'and 3'b can rotate freely past the blocking stop 31 pointing radially inward, the turbine blade 3'a strikes against the blocking stop 31, whereby the rotational movement of the control disk 2 is stopped. The turbine blade 3'a is selected such that in this blocking position the control disk 2 releases the radially inner inlet openings 8a of the paired adjacent inlet openings 8a, 8b via the associated slot segments 13 ' ₁ , 13' ₃ , whereby the outlet jet pattern S6 analogously Fig. 18 at the third shower head results.

If the actuating pin 28 is rotated further by 90 ° in the clockwise direction, it assumes its second blocking position, in which its lower blocking stop 30 points radially inward and abuts against it the turbine blade 3'b, as in FIGS FIGS. 27 and 28 shown while all other turbine blades 3 'and 3'a can pass freely the radially inwardly facing blocking stop 30. The turbine blade 3'b is again selected such that the control disk 2 retained in this second blocking position remains in the same way as the exit jet pattern S5 Fig. 17 at the third shower head supplies, by the respective slot segments 13 ' ₂ , 13' _{4 of} the control slot pattern 13 'respectively the radially outer Inlet opening 8b of the pair of radially adjacent inlet openings 8a, 8b release.

Upon further rotation of the blocking pin 28 by 90 ° in the clockwise direction then both blocking stops 30, 31 are again within the recess 32 of the housing side wall, without projecting radially inward, i. the blocking mechanism is again in its release position, in which the control disk 2 can rotate freely to effect the desired time variation of the Effervescent radiation characteristic.

The Fig. 29 to 31 illustrate a fifth shower head according to the invention, wherein for identical and functionally equivalent elements in turn the same reference numerals are used as for the shower heads described above Fig. 1 to 28 , so that reference can be made to the above explanations.

The shower head of the Fig. 29 to 31 comprises a modified housing 1 'having a fluid inlet 7' centrally provided on its upper end side and an integrated flow guiding structure 1'a, by means of which the fluid entering axially via the inlet 7 'is deflected in a direction with circumferential direction component. Such a flow guiding structure 1'a is known per se to a person skilled in the art and therefore does not require any further explanation here.

As a further modification to the spray heads explained above are the shower head of Fig. 29 to 31 the turbine blades are provided on a turbine wheel 3 ", which in this example is designed as a separate component from a control disk 2 _1. The turbine wheel 3" is coupled to the control disk 2 ₁ via a reduction gear in the form of a planetary gear. The planetary gear has an inner circumference of the annular control disk in this embodiment 2 ₁ formed outer ring gear 35, a turbine wheel 3 "arranged at the front sun gear 36 and an intermediate planetary gear 37. The turbine 3" is rotatably mounted with its sun gear 36 on a centrally projecting from the jet disk 4 ₂ bearing pin 38, and the planetary gear 37th is attached to an off-center on the inside of the jet disk 4 ₂ arranged bearing stub 39. Three retaining lugs 1'b arranged at 120 ° intervals on the inside of the housing side wall hold the annular control disk 2 _{1 in a} rotatable manner on its outside on the jet disk 4 ₂ .

The control disk 2 ₁ is provided with a control slot pattern of a plurality of circumferentially successively arranged control slots 40 of the same shape. Specifically, each control slot 40 has a radially inner portion 40a, a radially outer portion 40b, and an intermediate transition portion 40c. The radially inner portion 40a and the radially outer portion 40b each extend over a predetermined circumferential angular range at a constant radius, and the transition portion 40c extends between these two end slot portions 40a, 40b and thus with an additional radial component.

The jet disk 4 ₂ has on its inside slot-shaped inlet openings 8 'with a radially extending longitudinal axis and on its outer side corresponding to each inlet opening 8' has a substantially circular outlet opening 9. The inlet openings 8 'are provided in the circumferential direction one behind the other on the jet disk 4 ₂ , as are the outlet openings 9, ie the outlet openings 9 are at an equal radius. The respective outlet opening 9 is connected to the associated long-hole inlet opening 8 'via a through-channel 10, which has a tapering in a jet disk radial plane from the inlet opening 8' to the outlet opening 9 toward cross-section.

In other words, in this embodiment corresponds each slot entry opening 8 'via the passageway 10, which in turn has non-parallel side wall portions 12a, 12b for providing different jet exit directions by its conical shape, with an outlet opening 9 such that a radially inner region 8' a of the inlet opening 8 'via the side wall portion 12a with radially outwardly pointing direction component and a radially outer portion 8'b of the inlet opening 8' via the side wall portion 12b with radially inwardly extending component with the associated outlet opening 9 in connection. The inclined, conical side wall regions 12a, 12b of the passage channel 10 thus again form flow guide surfaces through which the fluid is supplied, depending on whether it is supplied via the radially inner region 8'a or the radially outer region 8'b of the respective inlet opening 8 ', emerges in different beam directions from the outlet opening 9, namely with radially outwardly or radially inwardly pointing beam direction component.

The control slots 40 are matched to the slot inlet openings 8 'in such a way that with their radially inner section 40a they define the radially inner area 8'a of the inlet openings 8' and with their radially outer section 40b the radially outer area 8'b of the inlet openings 8 'release. The transition section 40c of each control slot 40 causes the fluid supply to flow continuously into the through-channel 10 from the radially inner region 8'a to the radially outer region 8'b of the inlet openings 8 '. By contrast, the change from the outer radius to the inner radius occurs abruptly by the change from one to the next control slot 40, wherein the control slots 40 do not overlap in the circumferential direction.

In operation, the fluid, such as water in the case of a sanitary shower head, passes through the inlet 7 'in the showerhead housing 1' and is There by the flow guide 1'a with a circumferential direction component directed to the wings of the turbine wheel 3 ", whereby the turbine wheel 3" is set in rotation. The planetary gear 35, 36, 37 transmits the turbine wheel rotation in a stunted rotation of the control disk 2 ₁ relative to the housing 1 'fixed jet disk 4 _second The fluid passes radially out of the region of the turbine wheel 3 "into the region of the rotating control disk 2 ₁ provided with the control slot pattern 40 and passes through the control slots 40 via the respectively released radially inner or radially outer region 8 'a, 8'b of FIG Inlet openings 8 'in the passageways 10 and from these at the outlet side of the jet disk 4 ₂ via the outlet openings 9 with a variable-time beam direction.

Fig. 31 14 illustrates, in a longitudinal sectional view, a snapshot in which a left entrance opening is released through the radially outer control slot pattern section 40b in its radially outer region 8'b, whereby the fluid with radially inwardly directed component exits the associated exit opening, while a diametrically opposite entry opening passes through the radially inner portion 40a of the control slot pattern 40 is released in its radially inner region 8'a, so that there exits the fluid with radially outwardly directed component from the associated outlet opening 9. Overall, this results in a momentary spray pattern S7.

If the control disc 2 _{1 has turned a} little further until the in Fig. 31 left inlet opening is released in its radially inner region 8'a and correspondingly the opposite inlet opening is released in its radially outer region 8'b, the jet image S7 different jet pattern S8 results, in which the fluid from the left outlet opening with radially outward directed component and emerges at the right outlet opening 9 with radially inwardly directed component. By continuous, driven by the fluid rotation The control disk 2 ₁ thus again results in the desired temporal variation of the shower spray characteristic, which is determined by the vote of Steuerschlitzmusters 40 on the one hand and the inlet openings 8 'on the other hand in shape and arrangement. Depending on the number and shape of the control slots 40 and depending on the choice of the reduction by the planetary gear 35, 36, 37 different spray jet characteristics can be generated in the desired time sequence with abrupt or even, overlapping transitions as desired.

The FIGS. 32 to 34 illustrate in this regard a sixth shower head according to the invention with a comparison with the fifth shower head varied control slot design. Incidentally, the sixth shower head corresponds to the fifth shower head described above, so that below only needs to be discussed on the differences and otherwise reference is made to the above explanations to the fifth shower head.

Specifically includes the shower head of FIGS. 32 to 34 a control slot pattern on a modified so far control disk 2 ₂ , which includes a plurality of rectilinear control slots 41, which in turn are arranged in the circumferential direction one behind the other without overlapping. Each control slot 41 extends in the circumferential direction and additionally with a uniform radial component such that it has a radially inner end 41a on the radius of the radially inner regions 8'a of the inlet openings 8 'and with a radially outer end 41b on the radius of the radially outer Areas 8'b of the inlet openings 8 'is located. As a result, each control slot 41 releases the respective slot entry opening 8 'continuously depending on the direction of rotation from its radially inner area 8'a to its radially outer area 8'b or vice versa, followed by an abrupt change to the next control slot 41. This control slot pattern 41 thus causes the respective outlet opening 9 of the jet disk 4 ₂ a comparatively continuous transition from one to the other jet pattern, followed by an abrupt return to the first jet image.

Depending on the number and arrangement of the control slots 41 and the inlet openings 8 'can be adjusted synchronously same or groupwise different or irregularly distributed different beam directions for the totality of the outlet openings 9 at a respective time, which together give the respective instantaneous spray pattern of the shower head. In the example shown the FIGS. 32 to 34 are, in particular, out Fig. 34 can be seen, eight control slots 41 are provided, which extend in the circumferential direction approximately at the angular distance of the inlet openings 8 ', so that each slot 41 always about a next inlet opening 8' releases in its radially inner or outer region, if it has a previous inlet opening ' leaves. Like also out Fig. 34 can be seen, each control slot 41 passes over the respective inlet opening 8 'depending on the direction of rotation steadily passing from its radially inner portion 8'a to its radially outer portion 8'b or vice versa, so that there is a very continuous change from one to the other spray pattern, followed by an abrupt change of the beam image during the transition from one control slot 41 to the next.

Fig. 33 illustrates a snapshot accordingly Fig. 31 for this control slot variant. This will be an in Fig. 33 Left and diametrically opposite right inlet opening both released in their radially outer region 8'b of the associated control slots 41, so that the entering there fluid exits with radially inwardly facing component of the two associated outlet openings 9, which thus contribute to a corresponding spray pattern S9 , When the control disk 2 ₂ continues to rotate, this jet image S9 changes continuously to a jet image S10 indicated by dashed lines, in which the Fluid enters through the radially inner portions 8 'a of the two inlet openings shown and emerges from the associated outlet openings 9 with radially outwardly facing component.

The FIGS. 35 to 38 illustrate two more control disc variants in terms of design of Steuerschlitzmusters, see in particular the Fig. 35 and 37 , and a seventh or eighth shower head according to the invention equipped therewith, see in particular Fig. 36 or 38, these two shower heads incidentally the fifth and sixth shower head of FIGS. 29 to 34 correspond, in particular, the realization of the showerhead housing, the turbine wheel, the planetary gear and the jet disk concerns.

The embodiment according to the FIGS. 35 and 36 includes an annular control disk 2 ₃ with a control slot pattern of a plurality of circumferentially successively arranged control slots 42, each extending over about twice the angular distance of the inlet openings 8 'of the jet disk and a curved course with a central region 42 a, which is radially at the level of the radially inner Areas 8 'a of the inlet openings 8' is located, and have adjoining end portions 42b, 42c, in which the slot 42 continuously on the radius of the radially outer portions 8'b of the inlet openings 8 'merges. The control slots 42 are separated from each other by narrow radial web portions 43 of the control disk 2 ₃ . The webs 43 hold the area of the control disk 2 ₃ radially outside the control slots 42 with the area radially inside the control slots 42 together. The webs 43 can be chosen arbitrarily in their width, for example, with a width which is at most about equal to or at most about twice as large as the width of the control slots 42. The narrower the webs 43 are, the shorter is the time during which they cover the radially outer region 8'b of the respective inlet opening 8 'and thereby briefly interrupt the spray pattern.

The control slot pattern 42 provides the shower head according to the FIGS. 35 and 36 in that, during operation, the jet direction for each jet disk outlet opening continuously changes between the two jet patterns, which are given by the fluid inlet into the jet disk alternately through the radially inner region 8'a and the radially outer region 8'b of the inlet openings 8 '. In contrast to the shower heads of the FIGS. 29 to 34 , in which only the one beam direction change continuously, the other, however, is abrupt, results for the shower head of FIGS. 35 and 36 in both cases, a continuous change of jet direction.

The same applies to the shower head according to the FIGS. 37 and 38 , This shower head is the only difference from that of the FIGS. 35 and 36 modified so that the dividers 43 are replaced by narrow arcuate bridge elements 44. Accordingly, the shower head of the FIGS. 37 and 38 a modified control disk 2 ₄ , whose control slot pattern consists of a circumferentially continuous control slot 45, the course of which through the entirety of the control slots 42 in the shower head of FIGS. 35 and 36 given course corresponds to, for the shower head of the FIGS. 37 and 38 not the interruptions by the dividers 43 are present. Instead, with respect to the continuous control slot 45 radially inner part and the radially outer part of the control disc 2 _{4 are held together} by the bridge members 44.

In its function for temporal variation of the shower spray characteristic of the continuous control slot 45 largely corresponds to the control slot pattern 42 in the shower head FIGS. 35 and 36 , wherein the only difference is no interruption of the release of the radially outer region 8'b of a respective inlet opening 8 'when passing from one to a next control slot occurs. Rather, the shower head remains the FIGS. 37 and 38 this radially outer inlet opening region 8'b also released below the bridge elements 44, when the control disk 2 ₄ with one of the bridge elements 44 passes over this radially outer inlet opening region 8'b.

As the illustrated and explained above embodiments clear, the invention advantageously provides a shower head, which makes it possible, with a relatively movable to a jet disk control disc and a suitable vote provided in the control disk Steuerschlitzmusters and provided in the jet disc inlet openings, which correspond via suitable through-channels with jet disk outlet openings, to achieve a desired, time varying shower spray characteristic, without the need to use movable jet outlet elements. For this purpose, the passageways may be formed with inclined side walls as flow guide, and / or there may be pairs of closely adjacent inlet openings and corresponding outlet openings, which are fed alternately with the fluid.

The control disk can be driven by a suitable turbine blade structure of the incoming fluid itself. Optionally, the shown, reducing planetary gear or another, for this purpose per se known over or reduction gear can be provided. Furthermore, a conventional speed control for the control disk can be provided in a manner not shown, for example by a bypass to turbine drive nozzles, such as in the patent EP 0 900 597 B1 described. If desired, the control disk can advantageously be stopped in a desired position, so that a certain desired shower spray characteristic can be maintained constant. In the described blocking mechanisms, this is realized by a mechanical lock, which designed with suitable Turbine wings interacts. Alternatively, appropriate mechanical blocking means may be provided instead of on the turbine blades directly on the control disk. The blocking mechanism may be designed, as required, to hold the control disk in its relative position to the jet disk as shown in two blocking positions, or alternatively in only one or more than two blocking positions.

It is understood that the invention includes, in addition to the examples shown by way of example, numerous further embodiments, in particular also mixed forms of the examples shown, in which features of the same are combined, e.g. a jet disk with other than the shown patterns of the exit openings and the inlet openings and / or a control disk with a control slot pattern other than those shown, or a combination of the shown patterns.

Particularly advantageous application of the invention for shower heads of sanitary showers. However, it is of course also suitable for all other applications where there is a need for a shower head with time-varying Effervescent characteristics.
