Description

Shower head beam generating device for a variable-direction shower head beam
Technical Field
The invention relates to a shower head beam generating device having a housing and a beam guide, wherein the housing has a fluid supply and at least one beam outlet on an outlet side, through which the supplied shower head fluid flows out of the housing as a shower head beam having a main beam direction parallel or inclined to the housing outlet direction, and the beam guide is designed to periodically change the main beam direction of the shower head beam.
Background
Such a shower head beam generating device serves to obtain, by means of a periodically changing beam main direction of the shower head beam, the respective desired beam characteristics for the shower head beam formed by the delivered shower head fluid. The term shower head beam is used here to denote, unless otherwise stated, shower head beams which emerge from the respective beam outlet openings, so that, for a shower head beam generating device having a plurality of beam outlet openings, the individual shower head beams emerging from these beam outlet openings form a total shower head beam. The "main beam direction" is to be understood in this case to mean the direction in which the shower head beam, after it emerges from the beam outlet, leaves the housing of the shower head beam generating device. This does not exclude that a certain fluid fraction of the shower head beam does not exit from the beam outlet precisely along this beam main direction, but is slightly inclined with respect to the beam main direction, as in the case of shower head beams with divergent beam patterns. The "housing exit direction" is understood to mean the direction in which the shower head beam, which is not influenced by the beam guide, leaves the housing. This direction is mostly aligned with the axial or longitudinal axis of the spray outlet, which is mostly parallel to the longitudinal axis of the housing or perpendicular to the plane of the housing that encloses the shower head spray generating device in the spray outlet direction. When using the shower head jet generating device in a shower head, the jet outlet is usually located in or close to a shower head exit plane of the shower head, wherein the shower head exit plane is usually represented or defined by a so-called jet disk as an element closing the shower head on the outlet side, and the housing exit direction is in this case typically perpendicular or approximately perpendicular to the jet disk plane.
Shower head beam generating devices of this type are used, for example, in sanitary technology as shower head beam generating devices for sanitary installations. In this case, the shower head beam generating device can overall form a shower head of this type or a shower head for a shower head of this type or can be installed in a corresponding shower head or a corresponding shower head. Such sanitary shower heads are used, for example, as hand shower heads, head shower heads and side shower heads in showers or bathrooms and as kitchen shower heads for kitchen sinks. In this case, water is generally used as shower head fluid, and the periodic variation of the main direction of the jet of the shower head jet can be used in particular in shower heads of the sanitary bath to obtain a massaging effect with the shower head jet.
In the case of shower head jet generating devices of the type mentioned at the outset, which are of the known type, the jet guiding device comprises a nozzle body which is held on the housing in a rotationally or oscillatingly movable manner, which nozzle body contains the jet outlet and is set into a rotational or oscillatory motion by the fluid pressure of the supplied shower head fluid, so that the main jet direction of the shower head jet emerging from the jet outlet changes accordingly in time, for example, in a circular manner along a conical curvature or oscillates back and forth over an angular range of a fan shape. Such shower head beam generating devices are disclosed in DE 19912104 a1 and in patent documents DE 3915962C 1, US 4.018.385 and US 5.332.155.
In another type of shower head beam generating device, as disclosed in patent documents US 4.089.471 and DE 3736795C 2 and in publications DE 4031206 a1, DE 10108326 a1, DE 10231575 a1 and DE 102005002424 a1, the housing contains a plurality of beam outlet openings which are arranged annularly along a circular path which forms a circumferential path for one or more blocking bodies located there. The respective blocking body runs around on this circulating path, driven by the fluid pressure of the supplied shower head fluid. In this case, each time the blocking body moves past one of the beam outlet openings, it blocks the beam outlet opening which was not previously blocked by it for a short time and then releases it again. In this way, a pulsating massage beam characteristic is to be caused by the shower head beam emerging from the beam outlet.
Disclosure of Invention
The object of the present invention is to provide a shower head beam generating device of the type mentioned at the outset, which can be produced at relatively low cost and which can implement a periodic change of the shower head beam characteristics and in particular of the main direction of the shower head beam with a beam guidance means which can be implemented comparatively easily and is functionally reliable.
The present invention solves this problem by providing a shower head beam generating device having the features of claim 1. Advantageous developments of the invention which contribute to solve this and other problems are specified in the dependent claims, the content of which, including all combinations of features resulting from the claims cited, is hereby fully made the content of the present description by reference.
According to the invention, the beam guidance means comprises a circulating path formed in the housing and extending annularly around the beam outlet and a beam guidance unit arranged on the circulating path in a circulating manner, wherein the main beam direction of the shower head beam exiting the housing through the beam outlet changes depending on the position of the beam guidance unit on the circulating path, i.e. the main beam direction of the shower head beam changes depending on the position of the circulating path of the beam guidance unit as a result of the circulating movement of the beam guidance unit. "annularly surround the beam outlet by surrounding the trajectory" means, as understood by the person skilled in the art, that the center point of the beam outlet lies within a surface surrounded by the surrounding trajectory, which surface has a radial distance from the surrounding trajectory and is therefore not located on the surrounding trajectory itself.
By means of this measure, it is possible in a relatively simple manner for the shower head beam generating device to achieve a desired periodic variation of the main beam direction of the shower head beam emerging from the respective beam outlet and thus of the beam pattern or beam characteristic of the shower head beam or of the entire shower head beam consisting of a plurality of such shower head beams as a single beam. This can be used, for example, to provide the entire shower head beam with a massaging effect.
In this case, it is not absolutely necessary for the beam outlet itself to be moved, for example, as part of a movable nozzle, but rather the beam outlet can be formed stationary on the housing. Only the beam directing unit has to be arranged in a movable manner. However, their pivoting movement along a pivoting path which encloses the beam outlet can be realized with relatively little effort. Furthermore, no significant sealing problems occur here.
In operation of the spray jet generating device, the spray jet guiding unit runs around on its circular path and interacts with the spray jet outlet or with the shower fluid entering the spray jet outlet in such a way that the main spray direction of the shower spray exiting the housing at the outlet of the spray jet outlet changes as a function of the circular path position of the spray jet guiding unit, i.e. as a function of the changing circular path position of the spray jet guiding unit.
For the co-action of such a guided beam, any means that are usual per se for this purpose for the person skilled in the art can be used. For example, the beam guidance unit can have a fitting region with which it fits into the entry cross section of the beam outlet to a predeterminable extent, which varies or alternatively remains constant as a function of the circulating path position of the beam guidance unit, wherein in the last-mentioned case a periodic change of the main beam direction can also be brought about by: the engagement region of the beam guidance unit runs around along the entry cross section of the beam exit opening in the circumferential direction and thereby engages in this entry cross section in a direction which changes in time accordingly. In a corresponding embodiment, the flow rate of the shower head beam flowing through the beam outlet can therefore be kept constant over time, alternatively it can be varied over time, in particular also so that the flow rate is always kept greater than zero in every position of the beam guidance unit on the circulating trajectory, i.e. in this case no complete interruption of the shower head beam emerging from the beam outlet occurs.
Depending on the design of the beam guidance unit, in particular of the aforementioned fitting region and of the beam outlet, the periodically changing main beam direction of the shower head beam can be predefined with the desired characteristics. For example, the beam guidance unit and the beam outlet can be adjusted to one another in such a way that the main beam direction of the exiting shower head beam is deflected, i.e., is emitted in an additionally inclined or inclined manner, with respect to the emission direction of the housing, on the side facing away from the engagement region of the beam guidance unit in the beam outlet. In an alternative embodiment, the beam guidance unit can be used to deflect the main beam direction of the shower head beam to one side of the fitting region of the beam guidance unit. The effect of the beam guidance unit can also be influenced or changed by the choice of the material and/or the surface properties of the beam guidance unit, in particular the choice of the embedding region thereof, for example by the use of more hydrophilic or more hydrophobic materials or the use of surfaces with greater or lesser roughness. In this way, for example, the deflection angle, by which the shower head beam is deflected in its main beam direction, and/or the beam shape of the emerging shower head beam can depend on the material or surface properties of the beam guide unit in the region of the shower head fluid in contact with the beam guide unit.
It goes without saying that, depending on the needs and application, the shower head beam generating device can have only one or more such beam outlet openings with associated circulating rails and beam guiding units, or alternatively additionally one or more further conventional beam outlet openings without such circulating rails and beam guiding units.
In a further development of the invention, the housing has a plurality of beam outlet openings, to which a respective circumferential path extending around the beam outlet openings and a respective beam guiding unit arranged on the circumferential path in a circumferentially movable manner are assigned. This makes it possible to provide a complete shower head beam formed or combined from a corresponding plurality of shower head beams of the beam outlet, wherein the beam main directions of the shower head beams, which can be varied as required and depending on the application, can be changed synchronously or asynchronously with respect to one another by means of the circulating trajectory and the corresponding embodiment of the associated beam guidance unit. Each circulating path preferably surrounds only the respective associated beam outlet and does not additionally also surround one or more of the other beam outlets. In an alternative embodiment, the housing contains only a single beam outlet with an associated circulating path and beam guidance unit. In a corresponding embodiment, it can be provided that a plurality of such shower head beam generating devices are mounted with their housings in a single shower head or a single shower head, so that the shower head or the shower head has a plurality of beam outlet openings with individually assigned beam guidance means.
In a further development of the invention, the jet guidance unit has at least one jet guide body which is moved around on a circulating path by the fluid pressure of the supplied shower head fluid, is designed as a rolling body which rolls along the circulating path or as a sliding body which slides along the circulating path and guides the jet direction at least over a part of its circulating travel on the circulating path, partially engaging in the inlet cross section of the jet outlet. The rolling bodies can in particular be spheres or cylinders, and the sliding bodies can likewise be spheres or cylinders or bodies which are not shaped in any way, for example in the form of torus segments.
By "partially" it is meant that the beam guide does not completely close the entry cross section of the beam outlet, but covers or reduces it by a predefinable portion. The "corresponding portion mentioned of the circulating path on the circulating path" can be a punctiform portion, i.e. a single or a plurality of points along the circulating path or a portion of the circulating path having a presettable length. This represents an advantageous embodiment for the respective beam guide body and its movement drive and its beam guiding action. The spray head beam emerging from the beam outlet therefore changes its main beam direction as a result of the position or orientation of this partial coverage of the entry cross section of the beam outlet, which changes as the beam guide moves around on the circulating path.
In an advantageous embodiment, the beam guide partially engages in the entry cross section of the beam outlet along its entire path on the path of the path to guide the beam direction. In a further embodiment, the partial engagement of the beam guide in the entry cross section of the beam outlet is only present for a part of the circulating travel of the beam guide on the circulating trajectory, while the beam guide engages in the entry cross section of the beam outlet over the remaining part of its circulating travel on the circulating trajectory in a non-guiding beam direction. In a further embodiment, it can be provided that the beam guide completely blocks the entry cross section of the beam outlet over a part of its circulating travel on the circulating path, so that the beam outlet is blocked for the associated time interval, i.e. the associated shower head beam is temporarily interrupted. In an alternative embodiment to the drive by means of fluid pressure, a motor-driven drive for moving the beam guide around its path can be provided, for example.
In one embodiment of the invention, the beam guidance unit has a plurality of beam guidance bodies, which are arranged circumferentially along the circumferential path decoupled from one another or coupled to one another. The respective change pattern for the periodic change of the main beam direction of the shower head beam can thus be realized in a very flexible manner. The beam guide bodies circulating on the same circulating path can be of the same design or of different design types or designs depending on the requirements and the application. In an alternative embodiment, the beam guidance unit has only one single beam guidance body which runs around on a circulating path.
In one embodiment of the invention, the beam guidance unit has a rotary guide for the respective beam guidance body. The beam guide body can therefore be reliably guided in its rotational circulating movement on the circulating path, if necessary. The rotation guide mechanism can be realized by a rotation support mechanism, for example. This achieves an advantageous guiding means in order to keep the beam guiding unit in its movement on the circulating track. In an alternative embodiment, the beam guidance unit is freely movable, i.e. without a rotary bearing, along its circulating path and is guided, for example, by an associated path limiting wall of the circulating path. In an alternative embodiment, the beam guide body can be guided, for example, loosely or without positive guidance, around the circulating path or only by a corresponding design of the path limiting surfaces that define the circulating path.
In a development of the invention, a fluid chamber is formed in the housing, in which the circulating path is located and from which the beam outlet emerges on a chamber side which is directed axially in the housing exit direction, wherein the fluid chamber is delimited on the chamber side which is directed axially in the housing exit direction by a circulating guide surface of the circulating path which surrounds the beam outlet in an annular manner, on which circulating guide surface the beam guide unit is supported and which is delimited on a chamber side which is directed axially against the housing exit direction by a partition wall which has at least one fluid supply opening which opens into the fluid chamber. This represents a structurally advantageous embodiment for many applications, both with regard to the circulating path and with regard to the mutually coordinated position of the beam outlet opening, on the one hand, which emerges from the fluid chamber, and of the fluid delivery opening, on the other hand, which opens into the fluid chamber. The fluid feed opening can optionally open into the fluid chamber with a directional component directed in the circumferential direction of the circulating path, which can facilitate the driving of the beam guide by the fluid pressure of the fed fluid. In an alternative embodiment, the fluid feed opening can, for example, open radially from the outside or radially from the inside into a fluid chamber in which the circulating track is located.
In one embodiment of the invention, the circumferential guide surface has a limiting region facing radially inward toward the beam outlet, which limiting region extends with a directional component counter to the direction of the housing outlet. The limiting region thus designed can serve to limit the movement of the beam-guiding unit circulating along the circulating path in terms of its radially inward movement and thus prevent the beam-guiding unit from unintentionally blocking the beam exit opening. In an alternative embodiment, the circumferential guide surface ends radially inward without such a limiting region, wherein the beam guidance unit can be prevented from undesirably moving further radially inward by other means if necessary. This can be achieved, for example, by the application of a corresponding fluid pressure or by a limiting element separate from the encircling guide surface of the encircling track.
In one embodiment of the invention, the partition wall has a limiting wall region radially inward toward the beam outlet, which limiting wall region extends with a directional component in the direction of the housing outlet, or a limiting journal projects from the partition wall into the fluid chamber in the direction of the housing outlet, which limiting journal limits the circumferential path for the beam-guiding unit radially inward. The limiting wall region has the following functions, similar to the above-mentioned limiting region surrounding the guide surface: the beam guidance unit is prevented from undesirably moving further radially inward in the direction of the beam outlet during its circulating movement on the circulating path. The limiting journals which are provided as alternatives have the same function, and both alternatives represent a measure for achieving this which can advantageously be easily implemented on the partition wall. In an alternative embodiment, the separating wall lacks such a limiting means and, if necessary, the beam guidance unit is limited in its radial inward movement by further means, for example by the above-mentioned limiting region of the circumferential guide surface.
In a further embodiment of the invention, a bearing journal, on which the beam guidance unit is mounted in a rotationally movable manner, extends from the partition wall into the fluid chamber in the direction of the housing exit. In this embodiment, the bearing journal of the partition can act as a hub for the respective rotary bearing of the beam guidance unit.
In one embodiment of the invention, the housing has a base body with a beam outlet and a circumferential guide surface, which surrounds the beam outlet in a ring-shaped manner, and a cover body with a partition wall, which is connected to the base body. This represents a structurally simple embodiment of the housing consisting of two parts connected to one another, without necessitating further parts for the housing. In an alternative embodiment, the housing consists of three or more individual housing components.
In one refinement of the invention, the beam outlet has a tapering or stepped narrowing shape in the direction of the housing outlet or a tapering or stepped widening shape in the direction of the housing outlet. This represents a shape, which is optimized according to requirements and application, of the beam outlet and which can be selected in particular according to the desired beam characteristics of the shower head beam emerging from the beam outlet. In an alternative embodiment, the beam outlet can have, for example, a cylindrical shape with a constant passage cross section along its longitudinal axis.

In the figures, the shower head beam generating device according to the invention is shown by way of example in some advantageous forms. Fig. 1 to 3 show a shower head with an integrated shower head beam generating device, wherein the shower head can be used, for example, as a hand shower head for shower rooms and bathroom fixtures or as a kitchen shower head on a kitchen sink. One or more shower head beam generating devices according to the invention can be integrated into the shower head, one of which can be seen representatively in the views of fig. 2 and 3. Such shower heads and similar shower heads can also be a shower head beam generating device according to the invention in general.

The tilt angle α is kept less than 90 ° and preferably between 0 ° and 70 °, wherein the tilt angle can also be temporarily zero, i.e., the main beam direction SHThen at this point in time parallel to the housing exit direction GA. The shower head beam 4, which is illustrated in fig. 3 and 6 by its representative edge beams 4a, 4b, can, depending on requirements and system design, have a convergent beam course, a beam course with a diameter which remains essentially constant, or, as illustrated, a divergent beam course which has a beam angle β between its edge beams 4a, 4b, and the main beam direction SHAs is customary, this results as a central or average direction of the individual beam portions of the shower head beam 4 or as a longitudinal center direction of the shower head beam 4.
The individual beam outlet openings 3 of the shower head beam generating device can have any suitable shape, including conically or stepwise, as required and applicableNarrowed shape or along the housing injection direction GAConically or stepwise widening shapes or cylindrical shapes, wherein each beam outlet can have a circular cross section as in the illustrated example or alternatively, for example, an elliptical or polygonal cross section, respectively.

In the exemplary embodiments of fig. 1 to 3, 10, 15 and 17 to 22, the beam outlet 3 has a cylindrical shape with a shell outlet direction GAMaintaining a constant opening diameter. In the exemplary embodiment of fig. 16, the beam outlet 3 has a direction of emission G along the housingAA shape that widens stepwise. The respective selected shape of the beam outlet 3 influences the beam shape of the shower head beam 4 emerging therefrom, as is understood by the person skilled in the art.
The shower head beam generating device also comprises a beam guide mechanism which is designed to periodically change the main beam direction S of the shower head beam 4H. For this purpose, the beam guidance means comprise a circulating rail 5 formed in the housing 1 and extending annularly around the beam outlet 3, and a beam guidance unit 6 arranged on the circulating rail 5 in a circulating manner. The main beam direction S of the shower head beam 4 emerging from the housing 1 through the beam outlet 3HDepending on the respective instantaneous position of the beam guidance unit 6 on the circulating path 5, that is to say depending on the circulating path position of the beam guidance unit 6, which changes as a result of the circulating path movement. The housing emitting direction G when the beam guide mechanism is not presentAI.e. the direction in which the shower head jet 4 leaves the housing 1 after passing through the jet outlet 3, extends generally parallel to the longitudinal axis Ls of the jet outlet 3, as in the example shown.
During operation of the shower head beam generating device, the beam guidance unit 6 runs around on its circulating path and thus periodically changes the main beam direction S of the shower head beam 4H. To pairDepending on the respective system design, for example, in particular for the embodiments shown in fig. 1 to 3, 9 and 10 and 4 to 8, the main beam direction S of the shower head beam 4HFor example, on a conical curved surface, the longitudinal axis of which is given by the longitudinal central axis Ls of the beam outlet 3 or is parallel to the housing outlet direction GA. It is to be noted here that in the respective embodiments, as in the illustrated exemplary embodiment, the longitudinal axis Ls of the respective beam outlet 3 is parallel to the longitudinal axis L of the housing 1GIn particular, in the exemplary embodiments of fig. 1 to 3, 9 and 10, of the housing 1 of the shower head beam generating deviceGParallel to the longitudinal axis L of the shower or shower head 20BTo be oriented, the showerhead jet generating device is integrated into the showerhead 20.
In a corresponding embodiment, the housing 1 of the shower head beam generating device has a plurality of beam outlet openings 3. Thus, for example, the shower head beam generating devices according to FIGS. 4 to 8 each have six beam outlet openings 31To 36. For each beam outlet 31To 36Is assigned its own, surrounding track 5 extending around it1To 56And is arranged on the circulating track 5 in a manner of circulating motion1To 56Upper beam guiding unit 61To 66. In the embodiments of fig. 7 and 8, the beam directing unit 61To 66For the beam outlet 31To 36Is identically produced, in an alternative embodiment, the beam guidance unit 61To 66Are designed to be different from each other. Fig. 1 to 3 and 9 to 25 show a shower head beam generating device, the housing 1 of which has only one single beam outlet 3 with a circulating rail 5 and a beam guidance unit 6. In alternative embodiments, the shower head beam generating device comprises only two, three, four or five or more than six beam outlet openings 3, each having an associated circulating path 5 and beam guidance unit 6.
In an advantageous mannerIn one embodiment, the jet guidance unit 6 comprises at least one jet guidance body 7 which is moved around on the circulating rail 5 by means of the fluid pressure of the supplied shower head fluid, is designed as a rolling body which rolls along the circulating rail 5 or as a sliding body which slides along the circulating rail 5, and guides the jet at least over a part of its circulating travel on the circulating rail 5 such that the jet direction partially engages in the inlet cross section E of the jet outlet 3QIn (1). It goes without saying that this likewise includes the following possibilities, namely: the beam guide 7 forms a combined rolling and sliding body which runs in a combined rolling and sliding motion around the circulating rail 5 or which, depending on the circumstances, for example the acting fluid pressure and the coefficient of friction between the beam guide 7 and the circulating rail 5, executes a rolling and/or sliding motion on the circulating rail 5.
In the exemplary embodiments of fig. 1 to 3, 9 and 10, the beam guidance unit 6 comprises in particular a single beam guidance body 7, which is designed as a ball 7 a. The spherical diameter is selected such that the entrance cross section E to the beam outlet 3QIn upward projection, i.e. in projection perpendicular to the longitudinal axis Ls of the beam outlet 3, the ball 7a is at a certain degree BQEntrance cross section E fitted to the beam outlet 3QThat is to say the degree BQDetermined as the inlet cross section EQIs covered or overlapped by the beam guiding body 7 or the beam guiding unit 6, as is shown in fig. 10, 15 and 16 in a clear representation.
The beam guide body 7 is partially fitted to the entry cross section E of the beam outlet 3QThis has the result that, as shown by way of example in fig. 3 and 6, the shower head beam 4 is not continuously parallel to the longitudinal axis Ls of the beam outlet 3 and thus to the housing outlet direction G, as is the case in the followingAAnd the ejection is as follows: the beam guide unit 6 and in particular the beam guide body 7 are not present, but have, for example, a direction component pointing away from the fitted beam guide body 7 or the fitted ball 7a in the embodiment of fig. 3 and 6Quantum, that is to say arranged such that its main beam direction SHInclined to the longitudinal axis Ls of the beam outlet 3 or to the direction of emission G of the housingAWith a transverse component directed away from the ball 7 a. The rolling movement of the balls 7a along their rolling path around the track 5 therefore leads to the following result: the main beam direction S of the emitted shower head beam 4HEncircling on the mentioned conical curved surface.
The portion of the cross-sectional area of the jet outlet 3 that is partially covered by the jet guiding unit 6, i.e. the degree of engagement BQ, can be kept constant or varied during the circulating operation of the jet guiding unit 6, which means a corresponding constancy or variation of the flow rate of the shower head fluid flowing through the jet outlet 3, depending on the requirements and in particular the system design with regard to the design of the circulating rail 5 and the jet guiding unit 6. Thus, in the example shown, if the beam exit opening 3 has a circular cross section and the surrounding trajectory 5 has a circular shape concentric with the beam exit opening 3, the flow rate is correspondingly kept constant. In an alternative embodiment, the cross-section of the circumferential path 5 and of the beam outlet 3 can have a non-uniform configuration, for example the circumferential path 5 has a circular shape and the opening cross-section has an elliptical shape or vice versa.
It goes without saying that the main beam direction SHAnd in particular its direction of ejection G relative to the housingAThe tilt angle α of the beam deflection means 7 can be set or predefined in a desired manner by a corresponding design of the circulating rail 5 and the beam guidance means 6 and in particular of the beam deflection means thereof. The specifications required for this purpose can be ascertained empirically, for example by means of computer simulations and/or simple experiments. Likewise, the beam-directing unit 6 directs the outgoing shower head beam 4 in a main beam direction S by selecting the respective material and/or the respective surface properties of the beam-directing unit 6 or of its beam-directing body 7HAnd/or the effect of the beam shape can be influenced or adjusted in a desired manner, which can likewise be effected, if desired, by means of a computer modelAnd/or simple experimentation to ascertain.
Fig. 11 and 12 illustrate an embodiment variant in which the beam guide body 7 is designed as a sliding body which slides along the circulating rail 5, in the illustrated case in particular as a sliding body 7b in the form of a torus segment, which extends along the circulating direction of the circulating rail 5 within the range of a torus angle of approximately 90 ° and thus correspondingly within the range of an angle of approximately 90 °, alternatively within the range of any other torus angle. As can be seen in particular from fig. 11, the diameter d of the ring-surface segment-shaped sliding body 7bTThe situation described above, which is similar to the balls 7a, is slightly greater than the width W of the annular circumferential track 5USo that the radially inner part of the ring-surface segment-shaped sliding body 7b is partially fitted to the entry cross section E of the beam outlet 3 enclosed by the circumferential rail 5QThat is to say again by the predeterminable degree BQIt is covered. This, analogously to the case explained above of the balls 7a, in turn leads to the main beam direction S of the shower head beam 4HInjection direction G from the housingAThe desired deflection in the direction away from the ring-surface segment-shaped sliding body 7b, i.e. the beam main direction S in the position of the sliding body 7b in fig. 11HExtends into the plane of the drawing and has a directional component pointing downwards and to the right.
Alternatively, the beam guide body 7 or the beam guide unit 6 can be provided with a wing structure which, depending on the pattern of the turbine surface, acts as a fluid resistance surface in order to support the action of the fluid pressure of the supplied shower head fluid, so that the beam guide body 7 is driven in motion, as is shown in the form of a wing structure 21 for the ring-surface segment-shaped slide body 7b in fig. 11 and 12. In an alternative embodiment, the beam guide body 7 has no such wing structure and is merely set in its circulating motion by corresponding shaping and by the inflow of the shower head fluid, as is done in the remaining exemplary embodiments shown.
Such possible ways of inflow of the spray head fluid to the spray beam directing unit 6 or the spray beam directing body 7 are known to the person skilled in the art in many ways for elements in the spray head which are set in motion by the fluid pressure, for example in order to set a rotationally movable valve disk element or the like in rotation, which therefore does not need to be explained in more detail here. For this purpose, in particular, the fluid feed device 2 can be configured in such a way that it directs the supplied shower head fluid to the beam directing unit 6 or its beam directing body 7 with a fluid flow component directed in the circumferential direction around the rail 5.
Fig. 13 shows a variant in which the beam guidance unit 6 again has a sliding body 7c as a beam guidance body 7, which in this case extends over an angle of approximately 120 ° and has a flat engagement projection 22 on its radial inner side, with which it is partially engaged in a beam-deflecting manner in the inlet cross section E of the beam outlet 3 when the sliding body is inserted into the housing 1 of the shower head beam generating deviceQIn (1). In this embodiment variant, the width d of the ring-surface segment-shaped sliding body 7c is therefore greaterTNeed not be greater than the width W of the encircling track 5U
It goes without saying that, depending on the requirements and the application, a large number of other possible implementations for the beam guide body 7 are possible with regard to its external design and its rolling or sliding properties. Fig. 14 therefore shows another possible embodiment of the beam guide 7 as a slide 7d, which comprises a slide bead 23 from which a fitting shoulder 25 projects, with which the beam guide 7 is partially fitted to the inlet cross section E of the assigned beam outlet 3 when the beam guide 7 is on the circumferential rail 5QIn (1). In the illustrated design, the engagement shoulder 25 has an engagement front 26 which is curved in accordance with the, for example, circular edge of the spray outlet 3 and which can be advantageous for shaping the corresponding cross section of the shower spray 4.
In a corresponding wayIn an embodiment, the beam guidance unit 6 has a plurality of beam guidance bodies 7, which are arranged circumferentially along the circumferential rail 5, decoupled from one another or coupled to one another. In the exemplary embodiments according to fig. 7 and 8, 19 and 20 and 22 and 23, the beam guidance unit 6 therefore comprises three beam guidance bodies 7 for each beam outlet 3, respectively1、72、73Whereas in the other examples shown the beam directing unit 6 comprises only one beam directing body 7 per beam exit opening 3. It goes without saying that in alternative embodiments, the beam guidance unit 6 can have two or more than three beam guidance bodies 7.
In a corresponding embodiment, the respective beam guide body 7 is arranged freely, i.e. without forced guidance by a bearing, to roll and/or slide along the circulating rail 5, as in the exemplary embodiments according to fig. 1 to 16. In the exemplary embodiment of fig. 7 and 8, in particular, three beam guiding bodies 7 per beam outlet 31、72、73Each of which is formed by balls 7a, two of which have the same diameter and one of which has a relatively larger diameter and which are loosely inserted into the circulating track 5. It goes without saying that in an alternative embodiment, the three spherical beam guides 7 can be selected as desired, optionally differently1、72、73E.g., all diameters are the same or all three diameters are not the same.
In an alternative embodiment, the beam guidance unit 6 has a rotary guide 8 for the respective beam guidance body 7, as in the exemplary embodiment of fig. 17 to 25. In the example of fig. 17 to 23, the rotary guide 8 is formed as a rotary bearing having a bearing journal 18 as a hub, which is fixed to the housing, and a bearing sleeve 19, which is held on the bearing journal in a rotationally movable manner.
In the embodiment of fig. 17 and 18, three generally hemispherical shell bodies 17a, 17b, 17c are preferred radially outwardlyThe same, alternatively different angular distances project from the support sleeve 19, which in this case forms the parts of the beam-guiding unit 6 that contribute to the beam guidance and for this purpose in each case guides the beam direction in part to engage in the entry cross section E of the beam outlet 3QIn (1). In one of the three housing bodies 17a, 17b, 17c, as shown in fig. 18, or alternatively in two or all three of the three housing bodies 17a, 17b, 17c, a ball and/or slide 17d is inserted, which is supported radially outward on a wall 16 of the housing 1 of the shower head jet generating device, which wall delimits the circumferential track 5 radially outward, and rolls and/or slides on the circumferential track 5. In this embodiment of fig. 17 and 18, the beam guidance unit 6 in its entirety thus again forms a rotationally movably supported beam guidance body 7 that rolls and/or slides along a circulating path.
The housing bodies 17a, 17b, 17c can optionally be made as sliding bodies which slide along the circulating rail 5 and can thus themselves each be referred to as sliding, rotatably mounted beam guides 7. In an alternative embodiment, the one or more balls and/or sliding balls 17d can then be omitted.
In the exemplary embodiment of fig. 19 and 20, three spherical sliding bodies, which run in a sliding manner on the circulating rail 5 and which, like the ball embodiment in the exemplary embodiments of fig. 1 to 10, each guide the beam direction in each case partially engaging in the entry cross section E of the beam outlet 3, project radially outward from the bearing sleeve 19 at angular distances of 120 ° again, preferably equidistant from one anotherQSo that the three spherical sliding bodies each form a sliding, spherical beam guide body 71、72、73And generally represents a rotationally mounted, sliding embodiment of the beam guidance unit 6.
Fig. 21 shows a variant corresponding to the embodiment of fig. 19 and 20, with the difference that the spherical beam guide 71、72、73Are not arranged at equidistant angular spacings from one another, but are arranged one behind the other in the circumferential direction with contact. This results in a correspondingly modified beam shape of the shower head beam 4 emerging from the beam outlet 3, compared to the beam shape of the exemplary embodiment of fig. 19 and 20.
In the example of fig. 22 and 23, the beam directing unit 6 comprises a star-shaped beam directing body 7 which projects radially outward from the support sleeve 19 and has three arms 14a, 14b, 14c which are preferably arranged at equidistant angular spacings, each of said arms 14a, 14b, 14c in turn directing an entry cross-section E which is partially fitted in the beam direction to the beam outlet 3QAnd ends radially on the outside at the level of the circulating rail 5 in a circular bead receiving region having a circular opening in each case, in which a sliding bead and/or a ball 13 having a larger bead diameter in relation to the opening is received in each case in such a way that it rests on the circulating rail 5 and slides and/or rolls on it and is guided on the star-shaped beam guide body 7. The star-shaped beam guide body 7 can thus be moved around on the circulating rail 5 in a sliding and/or rolling manner by means of the sliding/rolling balls 13.
Fig. 24 shows another possible design for the beam guide body 7. In this embodiment, the beam guide body 7 is formed by a sliding ball 24 and an engagement lug 27 projecting from the sliding ball 24, the sliding ball 24 being set up for sliding movement around on the associated circulating rail 5, and the beam guide body 7 being partially engaged with the engagement lug 27 with the entry cross section E of the associated beam outlet 3QAnd the fitting web 27 has, in its end region opposite the slide bead 24, an inclined bore 28 which guides the jet direction and whose bore longitudinal axis runs obliquely to the vertical axis of the fitting web 27 and thus to the longitudinal axis Ls of the associated jet outlet 3 and defines the main jet direction S of the shower jet 4HThe method comprises the following steps: the shower head fluid flows through the inclined bores 28 before passing through the beam outlet 3. By the circulating movement of the sliding balls 24 on the circulating track 5,the longitudinal axis of the inclined bore 28 is correspondingly rotated about the web vertical axis, which in turn leads to the following results: the main beam direction S of the spray head beam 4HAnd varies cyclically substantially circumferentially along the cone envelope surface.
Fig. 25 shows, as a further variant, an embodiment of the beam guide 7, in which, instead of the slide balls 24 of fig. 24, scoop-shaped ball receptacles 29 are formed, in which slide balls or balls 30 are received, which are in turn provided for sliding or rolling movement on the associated circulating rail 5. The engagement lugs 27 with the oblique bores 28 already mentioned for fig. 24 are again guided out of the bead receptacles 29 at the opposite end region. Furthermore, in this example, the beam guide body 7 has a guide or bearing journal 31, with which the beam guide body 7 is rotatably mounted on an associated bearing journal receptacle, which is arranged on the housing 1 of the shower head beam generator and fixed to the housing, so that a corresponding rotary bearing for the beam guide body 7 is again realized, which guides the beam guide body in its rotational circulating movement while being supported on the circulating rail 5 by the balls/sliding balls 30.
In an advantageous embodiment of the shower head jet generating device according to the invention, as in the example shown, a fluid chamber 9 is formed in the housing 1, the circulating rail 5 is located in the fluid chamber 9, and the jet outlet 3 is axially guided from the fluid chamber 9 in a housing outlet direction GAOn the directed chamber side 9 a. The fluid chamber 9 is delimited on this chamber side 9a by a circumferential guide surface 5a of the circumferential rail 5, which surrounds the beam outlet 3 in a ring-shaped manner. As explained above, the beam guide unit 6 is supported on this circumferential guide surface 5a, for example, with its beam guide body 7. Axially against the housing discharge direction GAOn the oppositely directed chamber side 9b, the fluid chamber 9 is delimited by a partition wall 10, which has at least one fluid feed opening 11 into the fluid chamber 9 as a fluid feed for the housing 1 of the shower head fluidPart of the feeding mechanism 2.
The wall regions or surface regions of the confining fluid chamber 9 and in particular those bounding or defining the encircling track 5 are suitably designed in respect of their course or their shape in a manner adapted to the requirements, respectively. For example, the circulating guide surface 5a can each have a shape adapted to the cross-sectional shape of the beam guide unit 6 circulating on the circulating rail 5 or of its beam guide body 7 and/or a curved or linear shape, as can the opposite wall surfaces of the partition wall 10 and the wall surfaces of the housing 1 bounding the circulating rail 5 radially outward. This means that a corresponding modification of the shape of the limiting surfaces, which is realized in the example shown, can be realized in alternative embodiments, if necessary.
In a corresponding embodiment, the circumferential guide surface 5a of the circumferential guide track 5 has a limiting region 12 facing radially inwards towards the beam outlet 3, said limiting region having a directional component counter to the housing outlet direction GAExtension, as is realized in the example of fig. 15 and 16. This enables a reliable guidance of the beam guidance unit 6 or its beam guidance body 7 during the circulating operation on the circulating rail 5.
In a corresponding embodiment, the partition wall 10 comprises a limiting wall region 32, which is oriented radially inward toward the beam outlet and has a directional component in the direction of the housing outlet GAAs also achieved in the embodiment of fig. 15 and 16. This also enables a reliable guidance of the beam guidance unit 6 or its beam guidance body 7 during the circulating operation on the circulating rail 5. Furthermore, the limiting region 12 and the limiting wall region 32 can act individually or in combination as a stop which prevents the beam directing unit 6 or its beam directing body 7 from unintentionally moving radially inwards and completely or anyway blocking the beam outlet 3 to an undesired extent.
In a corresponding embodiment, the limiting journal 33 runs in the housing ejection direction GAFrom the partition wall 10 into the fluid chamber 9, the restriction shaftThe neck 33 delimits the circumferential path 5 for the beam guidance unit 6 radially inwards, as is achieved in the exemplary embodiment of fig. 1 to 10. In the example mentioned, the limiting journal 33 fixes the beam guidance unit 6 and in particular the beam guidance body 7 thereof radially inward in order to prevent unintentional displacement from the circulating rail 5 and in this way to hold the beam guidance unit 6 or the beam guidance body 7 on the circulating rail 5.
In the corresponding embodiment, the bearing journal 18 for the rotary bearing or rotary guide 8 already mentioned is guided from the partition wall 10 in the housing ejection direction GAInto the fluid chamber 9, as is the case in the exemplary embodiment of fig. 17 to 23, the beam guidance unit 6 being mounted on the bearing journal 18 in a rotationally movable manner.
In a corresponding embodiment, the housing 1 of the shower head beam generating device has, as in the exemplary embodiment shown, a base body 1a and a cover body 1b having a partition wall 10, the base body 1a having a beam outlet 3 and a circumferential guide surface 5a of the circumferential rail 5, which circumferentially surrounds the beam outlet 3, and the cover body 1b being releasably or non-releasably connected to the base body 1 a. In an alternative embodiment, the housing 1 of the shower head beam generating device can be formed by more than two housing parts.
As is apparent from the other exemplary embodiments shown and described above, the invention provides a shower head beam generating device which, during operation of the shower head, effects a periodic change in the direction of the shower head beam in a structurally simple and functionally reliable manner. This can be used, for example, to provide a shower head which has one or more such shower head beam generating devices and can thus output the delivered shower head fluid as a massage-acting overall shower head beam formed from the one or more shower head beams generated by the shower head beam generating devices.
