Description

[0001] The invention relates to a toilet shower device which is arranged in a functional position on the toilet bowl side and includes a shower rod which has a shower jet outlet nozzle which is designed to emit a shower jet with a jet direction component directed upwards in the functional position.

[0002] Toilet spray devices of this type have recently been increasingly used in European countries as a hygienic and environmentally friendly alternative to conventional toilet paper or wet wipes for cleaning the buttocks and intimate areas. In this case, the toilet spray device is arranged in its functional position on the toilet bowl side, i.e., to fulfill its cleansing spray function, it is located at a suitable location in or on a toilet bowl, also known as a toilet bowl. This distinguishes the toilet spray device under consideration here from other toilet spray devices that are arranged outside the toilet bowl adjacent to it at a suitable location, for example, as a hand-held shower attached to a wall of a toilet room with the associated shower hose.

[0003] Toilet spray devices of the type considered here have already been proposed on various occasions; see, for example, utility model documents CN 205894217 U, CN 203701234 U, CN 203393820 U, and CN 201826380 U. The toilet spray devices disclosed therein include one or two shower wands arranged side by side, which are preferably arranged on the toilet bowl so that they can be extended and retracted. To meet the different needs of users, particularly those of men and women, it is known to equip one shower wand with two different shower jet outlet nozzles or to arrange two shower wands with different shower jet outlet nozzles side by side on the toilet bowl.

[0004] The published patent applications DE 10 2020 215 025 and GB 2 202 764A1 A disclose shower jet generating devices with a shower jet outlet nozzle, which have a steering body rotating on an orbit in a nozzle chamber, which directs, i.e., deflects or guides, supplied shower fluid in a desired manner in order to provide a directionally variable shower jet. Due to this mode of operation, this nozzle type is referred to herein as a steering body circulating nozzle. The circulating movement of the steering body can, in particular, be driven by fluid pressure, i.e., by the pressure of the shower fluid introduced into the nozzle chamber.

[0005] The invention is based on the technical problem of providing a toilet spray device of the type mentioned at the outset, which can be realized with relatively low manufacturing effort and offers advantages in one or more aspects over the above-mentioned prior art, in particular with regard to functionality and / or user comfort.

[0006] The invention solves this problem by providing a toilet spray device with the features of claim 1. Advantageous developments of the invention are specified in the subclaims, the wording of which is hereby incorporated by reference into the description. This includes, in particular, all embodiments of the invention resulting from the combinations of features defined by the references in the subclaims.

[0007] In the toilet shower device according to the invention, the shower jet outlet nozzle is a steering body circulating nozzle with a nozzle chamber, a jet outlet opening leading out of the nozzle chamber at a nozzle chamber wall that is upper in the functional position, an orbit formed on a lower nozzle chamber wall opposite the upper nozzle chamber wall and surrounding a longitudinal axis of the steering body circulating nozzle and a steering body circulating on the orbit, wherein the steering body circulating nozzle is designed to emit the shower jet with a main jet direction that rotates around the nozzle longitudinal axis at an angle to the latter.

[0008] The toilet spray device according to the invention thus includes a special circulating nozzle as the shower jet outlet nozzle, the jet outlet opening of which leads out of the nozzle chamber at the nozzle chamber wall that is located at the top in the functional position of the toilet spray device or the circulating nozzle, while the circulating path for the circulating body is formed on the lower nozzle chamber wall opposite this upper nozzle chamber wall. The designs of the jet outlet opening on the one hand and the circulating path on the other hand can therefore be implemented independently of one another in the desired manner; the circulating path does not limit the design options for the jet outlet opening, and conversely, the jet outlet opening does not limit the design options for the circulating path, which extends as a closed, annular path around the longitudinal axis of the circulating nozzle, e.g., as a circular, oval, or elliptical path.

[0009] It turns out that the steering body circulating nozzle realized in this way offers particular advantages for emitting the shower jet with an upwardly directed jet direction component via the upper jet outlet opening, as is desired for the present application of the toilet shower device arranged in the functional position on a toilet bowl. By rotating the steering body along the orbit, a desired jet characteristic for the shower jet is also achieved, according to which the shower jet rotates with its main jet direction obliquely to the longitudinal axis of the nozzle, i.e. the shower jet moves with its main jet direction in a circular manner around a generally conical surface, wherein the conical surface to be understood generally in the present case can have any suitable, not necessarily circular, cross-section, in particular an oval cross-section. The term oval in the present case also includes, in particular, elliptical shapes.As is known per se, the orbital movement of the steering body can also be driven by fluid pressure; alternatively, other, conventional, rotating drive means can be used for this purpose.

[0010] In a further development of the invention, the jet outlet opening has an oval cross-section. This cross-sectional shape of the jet outlet opening proves to be advantageous for the present application in a toilet spray device, and it can, in particular, be an elliptical cross-section. In alternative embodiments, the jet outlet opening can, for example, have a circular or polygonal cross-section.

[0011] In a further development of the invention, the orbit has an oval shape. In this respect, too, it has been shown that this orbit shape very well meets the requirements for the present application in a toilet spray device, with regard to the desired spray characteristics of the spray provided by the steering body orbit nozzle. Alternatively, the orbit can have a circular shape, for example.

[0012] In one embodiment of the invention, a major semi-axis of the oval cross-section of the jet outlet opening and a major semi-axis of the oval shape of the orbit are parallel to each other. It has been shown that, for corresponding applications of the toilet shower device, this leads to favorable jet characteristics of the shower jet emitted by the steering body orbit nozzle.

[0013] In one embodiment of the invention, the main jet direction circulates along an oval path, the major semi-axis of which runs obliquely to a major semi-axis of the oval cross-section of the jet outlet opening and / or at an oblique angle to a major semi-axis of the oval shape of the orbit. Again, it has been shown that for corresponding applications of the toilet spray device or user needs, this jet characteristic of the spray emitted by the steering body circulating nozzle is advantageous for buttock / intimate cleansing.

[0014] In a further embodiment of the invention, the angle of inclination is in the range between 30° and 60°, in particular between 40° and 50°. Experimental results show that this angle range leads to optimal cleaning results and an optimal user experience for corresponding applications of the toilet spray device.

[0015] In one embodiment of the invention, a major semi-axis of the oval cross-section of the jet outlet opening and / or a major semi-axis of the oval shape of the orbit is oriented at an offset angle relative to a longitudinal axis of the shower bar, twisted around the nozzle's longitudinal axis. It has also been shown that, for corresponding applications of the toilet shower device, this leads to favorable jet characteristics of the shower jet emitted by the steering body orbit nozzle.

[0016] In a further embodiment of the invention, the offset angle is in the range between 30° and 60°, in particular between 40° and 50°. Experimental results also show that this offset angle range leads to optimal cleaning results and an optimal user experience for corresponding applications of the toilet spray device.

[0017] In a further development of the invention, a longitudinal axis of the jet outlet opening is parallel to the longitudinal axis of the nozzle, and the steering body circulating nozzle has a plurality of inlet openings which are arranged circumferentially spaced from one another around the longitudinal axis of the nozzle, specifically in the lower nozzle chamber wall in the region of the orbit, and open into the nozzle chamber, with their longitudinal axes running obliquely to the longitudinal axis of the nozzle with a directional component in the circumferential direction of the orbit. Surprisingly, it has been found that this configuration of the steering body circulating nozzle, with regard to the position of the inlet openings in the nozzle chamber, leads to particularly good results with regard to the supply and directing of the shower fluid to provide the desired shower jet. In alternative embodiments, the inlet openings can be provided, for example, on a side wall of the nozzle chamber between the upper and lower nozzle chamber walls.

[0018] In one embodiment of the invention, a cross-sectional area of ​​each of the inlet openings is smaller than a cross-sectional area of ​​the jet outlet opening. This dimensioning measure for the inlet openings relative to the jet outlet opening proves to be very advantageous for the present application of the toilet shower device. In this and other embodiments of the invention, the ratio of the total inlet cross-section, i.e. the sum of the cross-sectional area of ​​the one or more inlet openings, to the outlet cross-section, i.e. the sum of the cross-sectional area of ​​the one or more jet outlet openings, can be used to adapt the jet character according to the desired specifications for the respective shower jet.

[0019] In a further development of the invention, the steering body is a spherical body rolling or sliding on the orbit, the spherical diameter of which essentially corresponds to a maximum chamber height of the nozzle chamber in the region of the orbit.

[0020] This represents an advantageous implementation for the steering body. Since the maximum chamber height of the nozzle chamber essentially corresponds to the spherical diameter of the spherical body or is only slightly larger to allow the spherical body to move freely in the nozzle chamber, the spherical body is guided very securely on its orbit by the adjacent nozzle chamber walls, which can promote the stability of the provided shower jet in its jet characteristic that periodically revolves around the nozzle's longitudinal axis. In alternative embodiments, the steering body can have any other shape known per se from conventional steering body circulating nozzles, and / or the maximum steering body diameter can, in appropriate cases, be significantly smaller than the maximum nozzle chamber height in the area of ​​the orbit, e.g., only 70% or less of the maximum nozzle chamber height.

[0021] In a further development of the invention, the toilet spray device includes a second shower jet outlet nozzle configured as a guide-path nozzle for emitting a second shower jet with, in the functional position, an upwardly directed jet component and a main jet direction that periodically tilts in a jet plane between two end positions under fluid pressure. In the two end positions, the main jet direction runs on opposite sides of a longitudinal axis of the guide-path nozzle, each at an angle to this guide-path nozzle longitudinal axis. The guide-path nozzle includes a fluid-pressure-controlling nozzle chamber, a jet outlet opening leading out of the nozzle chamber, and a chamber wall delimiting the nozzle chamber, which acts as a guide path for the second shower jet.

[0022] This feature further enhances the functionality of the toilet spray device and user comfort by providing two different spray jets, each with different jet characteristics as needed. Depending on the configuration and preference, both spray jets can be activated simultaneously, or one or the other can be activated selectively. The presence of two moving jet types allows for optimized cleaning performance with relatively low water consumption thanks to the corresponding jet movement of the two spray jets.

[0023] In this case, the second shower jet outlet nozzle is specifically designed as a steering path nozzle, which in this case is understood to mean a nozzle that has a steering path for steering, i.e., directing or guiding, the shower fluid in order to form the second shower jet from the supplied shower fluid and deliver it with the corresponding jet characteristics via the associated jet outlet opening. In this case, the jet characteristics include a periodically tilting movement of the shower jet with its main jet direction in a jet plane, wherein the switching or reversing in the respective end position is fluid pressure-driven, i.e., solely by the fluid pressure effects of the shower fluid in the nozzle chamber. The nozzle chamber accordingly acts on the movement of the shower jet by fluid pressure control.The two end positions lie in a jet plane in which the shower jet tilts along its main jet direction, specifically on opposite sides of the longitudinal axis of the deflection nozzle, each at an angle to the latter. The deflection path for the deflection of the shower jet is provided by the chamber wall surrounding the nozzle chamber; that is, corresponding sections of this chamber wall act as a deflection path for the shower fluid and the resulting shower jet. The deflection nozzle therefore requires no moving parts.

[0024] In alternative embodiments, the toilet spray device can include a second spray jet outlet nozzle of a different type, e.g., this can be another steering body circulating nozzle. Furthermore, in corresponding implementations, the toilet spray device can have a third and possibly one or more additional spray jet outlet nozzles.

[0025] In one embodiment of the invention, the guide rail nozzle is arranged on the shower bar, or the toilet shower device includes, in addition to the shower bar as the first shower bar, a second shower bar on which the guide rail nozzle is arranged. In the former case, a single shower bar is sufficient for the toilet shower device to accommodate both shower jet outlet nozzles. In the latter case, each of the two shower jet outlet nozzles is assigned its own shower bar. If necessary, the shower bars can be arranged on the toilet bowl so that they can be extended and retracted independently of one another.

[0026] In a further embodiment of the invention, a functional position of the second shower rod lies parallel next to a functional position of the first shower rod, i.e. the longitudinal axes of the shower rods run parallel in the functional position. This represents a favorable positioning of the two shower rods for most applications. It can be advantageous if the respective shower rod is only in the functional position during active operation and assumes a rest position during inactive periods, in which it is, for example, retracted or retracted compared to the functional position. In alternative embodiments, the two shower rods can be arranged such that in their functional position they run with non-parallel longitudinal axes. Furthermore, in corresponding implementations the toilet shower device can have a third and optionally one or more further shower rods.

[0027] In another embodiment of the invention, the nozzle chamber of the guide-track nozzle includes an inlet-side mouth region, an annular chamber region surrounding the rear of the mouth region, and an outlet region adjoining the mouth region and the annular chamber region with two delimiting jet system walls on opposite sides of the guide-track nozzle's longitudinal axis. This design of the nozzle chamber enables, in a structurally advantageous manner, the provision of the automatically fluid-pressure-driven, periodic tilting movement of the associated spray jet between its two end positions.

[0028] In a further embodiment of the invention, the jet system walls each include a convex, channel-widening, first system wall region and a concave, channel-narrowing, second system wall region adjoining it in the direction of the associated jet outlet opening, forming a first, diagonally outward-running system wall section, a subsequent second, diagonally inward-running system wall section, and a final, third, diagonally outward-running system wall section. Experimental studies have shown that this design of the jet system walls is particularly advantageous for providing optimal jet characteristics for the shower jet and its periodic, tilting back-and-forth movement, specifically for the toilet shower device.By appropriately designing the various system wall sections, the shower jet to be provided can be adjusted as desired with regard to its maximum exit angle and with regard to the switching frequency of its periodic movement between the two end positions.

[0029] In a further embodiment of the invention, a radius of curvature of the respective first system wall region lies in a range from 0.3 mm to 0.6 mm, in particular between 0.43 mm and 0.47 mm. In another embodiment of the invention, a radius of curvature of the respective second system wall region lies in a range from 1.2 mm to 1.6 mm, in particular between 1.48 mm and 1.53 mm. In another embodiment of the invention, an angle between the jet system walls in the region of the respective second system wall section lies in a range from 100° to 120°, in particular between 102° and 108°. In another embodiment of the invention, a jet deflection angle of the steering path nozzle lies in the range between 12° and 20°. It can be seen that with these special dimensioning measures, individually and in combination, the characteristics of the emitted shower jet can be further optimized for the intended purpose.

[0030] In another embodiment of the invention, the main jet direction of the shower jet of the steering body circulating nozzle circulates along an oval path, with an angle between respective extreme positions of the main jet direction at reversal points of the oval path preferably being in the range between approximately 6° and approximately 20° for the jet deflection parallel to a major semi-axis and preferably in the range between approximately 3° and approximately 10° for the jet deflection parallel to a minor semi-axis of the oval path. This dimensioning measure proves to be advantageous for achieving the desired cleaning effect for most applications.

[0031] It turns out that these value ranges for the radius of curvature or the angle of inclination of the relevant system wall area lead to an optimal jet characteristic of the corresponding shower jet for the present application of the toilet shower device.

[0033] Fig. 1 shows an implementation of the toilet shower device according to the invention, which includes a single shower rod 1 having a shower jet outlet nozzle in the form of a steering body circulating nozzle 2. The toilet shower device is in Fig. 1shown arranged in a functional position on the toilet bowl side, in which the shower wand 1 is also located in its functional position on a toilet bowl TS, as is known per se for toilet shower devices arranged on the toilet bowl side. The shower wand 1 can preferably be retracted or retracted from the shown functional position, in which it is located in or above a bowl space formed by the toilet bowl TS, into an initial position or rest position, as is also known per se. For example, the shower wand 1 can be moved or extended or retracted between the rest position and the functional position via a drive unit with a gear transmission. Preferably, the shower wand is arranged in its rest position for the most part in an area outside the bowl space, in particular sunk or retracted into a bowl body of the toilet bowl TS that encloses the bowl space.

[0034] The steering body circulating nozzle 2 includes a nozzle chamber 3 and a jet outlet opening 5, which leads out of the nozzle chamber 3 at a nozzle chamber wall 4 which is upper in the functional position of the shower rod 1, ie on the top side, wherein this nozzle chamber wall 4 delimits the nozzle chamber 3 on the top side, as can be seen in particular from the Figures 4 to 9 visible. As can also be seen there, the steering body circulating nozzle 2 further includes an orbit 7 which surrounds a longitudinal axis 2 L of the steering body circulating nozzle 2, ie extends around it, and a steering body 8 circulating on the orbit 7. The orbit 7 is formed on a lower nozzle chamber wall 6 opposite the upper nozzle chamber wall 4.

[0035] The steering body circulating nozzle 2 is designed to deliver a shower jet BS with a jet direction component Ks directed upwards in the functional position of the shower rod 1, with a main jet direction HS of the shower jet BS circulating around the nozzle longitudinal axis 2 L at an angle. This jet behavior of the shower jet BS is in Fig. 11 illustrated, see the illustrative orbiting arrow Pu there. Fig. 12 shows a schematic side view of the shower jet BS circulating in this way from the steering body circulating nozzle 2 of the shower bar 1 around the nozzle longitudinal axis 2 L. As can be seen in particular from Fig. 11 As can be seen, the shower jet BS moves with its main jet direction HS around a generally conical surface.

[0036] In advantageous implementations, the respective shower bar containing the steering body circulating nozzle 2, such as the shower bar 1 or the shower bars 1 1 and 1 2 , is arranged at a rear region of the toilet bowl TS in such a way that the shower jet BS is emitted from the steering body circulating nozzle 2 at an angle of approximately 40° to approximately 65°, in particular between approximately 50° and approximately 55°, to the vertical, obliquely upwards and forwards.

[0037] Fig. 2 shows the toilet shower device according to the invention in an embodiment with two shower rods 1 equipped with guide rail nozzles, a first shower rod 1 1 and a second shower rod 1 2 , which can preferably be moved independently of one another into their respective functional positions on a toilet bowl of the type of the toilet bowl TS from Fig. 1 can be brought, e.g. by extending from a starting or resting position in a similar way as above for the shower rod 1 of Fig. 1 In the example of the Fig. 2The functional position of the second shower rod 12 is parallel to the functional position of the first shower rod 11, wherein one shower rod preferably remains in its initial / rest position when the other shower rod is in its functional position. During operation of the toilet shower device according to Fig. 2 the shower rod 1 1 preferably functions for cleaning a female buttocks and a female intimate area, the shower rod 1 2 preferably functions for cleaning a male buttocks.

[0038] In advantageous embodiments, the jet outlet opening 5 of the steering body circulating nozzle 2 has an oval cross-section, in particular an elliptical cross-section. This is the case in the example shown, the view from Fig. 7 shows a corresponding oval or elliptical part of the cross-section of the jet outlet opening 5.

[0039] In advantageous embodiments, the orbit 7, as in the example shown, has an oval shape, in particular an elliptical shape, as in Fig. 9 visible.

[0040] In corresponding realizations, as in the example shown, a major semi-axis 5 G , in Fig. 7 the diameter of the jet outlet opening 5 extending in the left-right direction, the oval cross section of the jet outlet opening 5 and a major semi-axis 7c, in Fig. 9 the oval orbit diameter in the left-right direction, the oval shape of the orbit 7 are parallel to each other. Accordingly, the minor semi-axes 5 k , 7 k of the oval cross-section of the jet outlet opening 5 and the oval shape of the orbit 7 are parallel to each other, in the Figures 7 and 9 the respective diameters in top-bottom direction.

[0041] In corresponding implementations of the steering body circulating nozzle 2, the main jet direction HS of the shower jet BS emitted by the steering body circulating nozzle 2, as in the example shown, revolves on an oval path 9, the major semi-axis 9 G of which runs obliquely to a major semi-axis 5 G of the oval cross-section of the jet outlet opening 5 and / or at an oblique angle α obliquely to a major semi-axis 7 G of the oval shape of the orbit 7. Both properties are realized in the examples shown.

[0042] Fig. 13shows an impact diagram for the shower jet BS of the steering body circulating nozzle 2 in a plane perpendicular to the nozzle longitudinal axis 2 L , wherein the directions of the major semi-axes 5 G , 7 G of the jet outlet opening 5 and the orbit 7, which coincide in this exemplary embodiment, are referred to as the x-direction and the direction perpendicular thereto as the y-direction. The x-direction is preferably a direction parallel to a longitudinal axis 1 L of the shower bar 1 or inclined at an acute angle to it. As can be seen therefrom, the impact maximum, i.e. the maximum jet intensity of the shower jet BS, lies in an oval or elliptical ring region. In other words, the main jet direction HS of the shower jet BS revolves on the said oval path 9 with the major semi-axis 9 c and a minor semi-axis 9 k perpendicular thereto. The oblique angle α can, in appropriate designs, be between 0° and approx. 60°, in particular between approx. 30° and approx.60° or, more specifically, between approximately 40° and approximately 50°. It should be noted that the angular orientation of the oval path 9 of the impact characteristic of the shower jet BS changes with the changing distance of the shower jet BS from the steering body circulating nozzle 2, i.e., the oblique angle α changes slightly with the changing distance.

[0043] If it is desired that the major semi-axis 9 G of the oval track 9 for the main jet direction HS of the shower jet BS runs parallel to the longitudinal axis of the toilet bowl TS and thus generally also parallel to the longitudinal axis 1 L of the shower rod 1 at a predeterminable target distance of the impact surface to the jet outlet opening 5 of the steering body circulation nozzle 2 or to the shower rod 1, the jet outlet opening 5 and / or the orbit 7 are consequently oriented in their angular position on the shower rod 1 in such a way that their major semi-axes 5 G , 7 G run obliquely to the longitudinal axis 1 L of the shower rod 1 at a correspondingly previously determined value of an offset angle α1.

[0044] In Fig. 20In this regard, an example is illustrated in which the major semi-axes 5c, 7c of the jet outlet opening 5 and the orbit 7 are each oriented at the offset angle α1 relative to the longitudinal axis 1 L of the shower bar 1 around the longitudinal axis 2 L of the steering body orbit nozzle 2, wherein in this case the offset angle α1 is approximately 45° and it can be seen that at the specified target distance of the impact surface of the shower jet BS from the shower bar 1, the oval path 9 for the main jet direction HS of the shower jet BS is oriented with its major semi-axis 9 G approximately parallel to the shower bar longitudinal axis 1 L. Analogously, in Fig. 2 It can be seen that an outlet oval of the steering body circulation nozzle 2 is oriented with its major semi-axis obliquely to the shower rod longitudinal axis 1 L. In general, the offset angle α1, like the oblique angle α, is preferably in an angular range between approximately 0° and approximately 60°, in particular between approximately 40° and approximately 50°.

[0045] The corresponding jet deflection angles for the shower jet BS, ie the angle between the respective extreme positions at the reversal points of the oval or elliptical ring area, are for the jet deflection parallel to the major semi-axis 9 G preferably in the range between approx. 6° and approx. 20°, for the jet deflection parallel to the minor semi-axis 9 k preferably in the range between approx. 3° and approx. 10°.

[0046] This jet characteristic of the shower jet BS of the steering body circulating nozzle 2 results from the steering function of the steering body 8 rotating on the orbit 7. The supplied shower fluid is applied to the steering body 8 and is thereby deflected to this side relative to the nozzle longitudinal axis 2 L and exits as a shower jet BS with a main jet direction HS deflected accordingly from the direction of the nozzle longitudinal axis 2 L from the jet outlet opening 5. If Fig. 11the steering body 8 is located on the right side of the nozzle chamber 3, the main jet direction HS of the shower jet BS follows the dashed line when the steering body 8 is in Fig. 11 Located on the left side of the nozzle chamber 3, the main jet direction HS follows the solid line. In other words, the orbital movement of the steering body 8 on the orbital path 7 causes the main jet direction HS of the shower jet BS to revolve around the nozzle's longitudinal axis 2L.

[0047] In advantageous embodiments, a longitudinal axis 5 L of the jet outlet opening 5 is parallel to the nozzle longitudinal axis 2 L , and the steering body circulating nozzle 2 has a plurality of inlet openings 10, as in the example shown. The inlet openings 10 are arranged circumferentially spaced from one another around the nozzle longitudinal axis 2 L in the lower nozzle chamber wall 6 in the region of the orbit 7, as can be seen from Fig. 9The inlet openings 10 open into the nozzle chamber 3 in such a way that their longitudinal axes extend obliquely to the nozzle longitudinal axis 2 L with a directional component in the circumferential direction of the orbit 7.

[0048] In the example shown, the inlet openings 10 are formed by outlets of associated, essentially straight inclined channels 11, which open out of a distribution chamber 12 located upstream of the nozzle chamber 3, as can be seen from the Figures 5, 6 and 8 can be seen. Consequently, the shower fluid enters the nozzle chamber 3 via the inlet openings 10 with a corresponding directional component in the circumferential direction of the orbit 7 and, with its fluid pressure, drives the steering body 8 to its orbital movement on the orbit 7.

[0049] In corresponding embodiments, a cross-sectional area of ​​each of the inlet openings 10 is smaller than a cross-sectional area of ​​the jet outlet opening 5. This is the case in the example shown.

[0050] In advantageous embodiments, the steering body 8, as in the example shown, is a spherical body rolling and / or sliding on the orbit 7, the spherical diameter of which essentially corresponds to a maximum chamber height of the nozzle chamber 3 in the region of the orbit 7. In other words, in this case, the height of the nozzle chamber 3 is only so much greater than the diameter of the steering body 8 that an unhindered orbital movement of the steering body 8 on the orbit 7 is possible. Due to the only slightly higher nozzle chamber 3, the steering body 8 remains largely guided by the adjacent nozzle chamber walls during its orbital movement. In particular, the upper nozzle chamber wall 4 limits a lifting movement of the steering body 8 from the lower nozzle chamber wall 6, on which the orbit 7 is formed, wherein the lifting movement is caused by the effervescent fluid supplied via the inlet openings 10 on the lower nozzle chamber wall 6.

[0051] In advantageous embodiments, the toilet shower device according to the invention comprises a second shower jet outlet nozzle which is designed as a guide path nozzle 13 for emitting a second shower jet BS 2 with a jet direction component K S2 directed upwards in the functional position of the toilet shower device and with a main jet direction HS 2 which moves periodically in a jet plane between two end positions BE 1 , BE 2 in a tilting manner driven by fluid pressure.

[0052] Such a guide rail nozzle 13 is provided in the shower rod 1 according to the Figures 1 and 3 to 18 and in the first shower bar 1 1 of Fig. 2 provided, namely in the longitudinal direction of the shower rod 1 with a distance to the steering body circulation nozzle 2 closer to the free shower rod end, as for example from the Figures 1 to 5 visible. The Figures 4 , 5 , 10 , 14 , 17 and 18show the guide nozzle 13 in a section parallel to this jet plane. Figures 14 , 17 and 18 illustrate the second shower jet BS 2 in these end positions BE 1 , BE 2 . As can be seen from this, the main jet direction HS 2 of the second shower jet BS 2 in the two end positions BE 1 , BE 2 runs on opposite sides of a longitudinal axis 13 L of the guide track nozzle 13, in each case obliquely to this guide track nozzle longitudinal axis 13 L .

[0053] The guideway nozzle 13 includes a fluid pressure-controlling nozzle chamber 14, a jet outlet opening 15 leading out of the nozzle chamber 14, and a chamber wall 16 delimiting the nozzle chamber 14, which acts as a guideway for the second shower jet BS 2. These features of the guideway nozzle 13 are described, for example, in the Figures 5, 10 , 14 , 17 and 18 to recognize. Fig. 15illustrates in a schematic side view the second shower jet BS 2 moving back and forth in the jet plane between the two end positions BE 1 , BE 2 , as it is emitted by the guide track nozzle 13 during operation. Fig. 16 illustrated in an impact diagram analogous to that of Fig. 13 that and how, as a result, the area of ​​maximum jet intensity of the shower jet BS 2 is a correspondingly linear impact area which extends essentially in the x-direction, ie essentially parallel to the shower rod longitudinal axis 1 L . The associated jet deflection angle, ie the angle between the two end positions BE 1 , BE 2 , is preferably in the range between approximately 12° and approximately 20°.

[0054] In advantageous implementations, the respective shower bar containing the guide rail nozzle 13, such as the shower bar 1 or the shower bar 11, is arranged at a rear region of the toilet bowl TS in such a way that the shower jet BS 2 is emitted from the guide rail nozzle 2 at an angle of approximately 40° to approximately 65°, in particular between approximately 55° and approximately 60°, to the vertical, obliquely upwards and forwards.

[0055] In corresponding designs, the steering track nozzle 13 is arranged on the same shower bar 1 as the steering body circulation nozzle 2. This is the case with the shower bar 1 of Fig. 1 and the first shower wand 1 1 from Fig. 2 Alternatively, the steering track nozzle 13 can be arranged on a different shower bar 1 than the steering body circulation nozzle 2. This is the case in a variant of the example of Fig. 2the case in which the first shower bar 1 1 has only the steering track nozzle 13 and not additionally the steering body circulation nozzle 2. As already mentioned above, if there are several shower bars, such as the first and second shower bars 1 1 , 1 2 , the functional positions of these shower bars can be oriented parallel to one another, or alternatively non-parallel.

[0056] In general, the steering body circulating nozzle 2 is particularly suitable for cleaning the anus, while the steering path nozzle 13 is preferably suitable for cleaning the female intimate area.

[0057] In advantageous embodiments, the nozzle chamber 3 of the guide track nozzle 2, as in the example shown, includes an inlet-side mouth region 14a, an annular chamber region 14b surrounding the mouth region 14a at the rear, and an outlet region 14c adjoining the mouth region 14a and the annular chamber region 14b in the flow direction of the shower fluid, wherein the outlet region 14c has two delimiting jet system walls 16a, 16b on opposite sides of the guide track nozzle longitudinal axis 13i_, as is particularly shown in the Figures 10 , 14 , 17 and 18 can be seen.

[0058] In advantageous implementations, the blasting system walls 16a, 16b, as in the example shown, each include a convex channel-widening, first system wall region 17 and a concave channel-narrowing, second system wall region 18 adjoining it in the direction of the associated beam outlet opening 15. This design of the system wall regions 17, 18 accordingly provides a first, obliquely outwardly extending system wall section 19, a subsequent second, obliquely inwardly extending system wall section 20 and a final, third, obliquely outwardly extending system wall section 21. The associated dimensioning measures are described in Fig. 19 illustrated for a possible embodiment.

[0059] As in Fig. 19As illustrated, in advantageous embodiments, a radius of curvature R1 of the respective first contact wall region 17, specifically of its upstream part bulging toward the longitudinal axis 13 L, lies in a range from 0.3 mm to 0.6 mm, in particular between 0.43 mm and 0.47 mm. Furthermore, in advantageous embodiments, a radius of curvature R2 of the respective second contact wall region 18, specifically of its upstream part bulging away from the longitudinal axis 13 L, lies in a range from 1.2 mm to 1.6 mm, in particular between 1.48 mm and 1.53 mm. Furthermore, in advantageous embodiments, an angle β of the respective second system wall section 18, especially the angle between its downstream, obliquely inwardly extending system wall sections 20, lies in a range of 100° to 120°, in particular between 102° and 108°.A radius of curvature R3 of the section bulging toward the longitudinal axis 13L directly in front of the third, obliquely outwardly extending contact wall section 21 is preferably in a range from 0.3 mm to 0.9 mm, in particular between 0.7 mm and 0.75 mm. An angle δ, at which the blasting contact walls 16a, 16b extend toward one another in front of the convexly channel-widening, first contact wall region 17, is preferably in a range from 30° to 35°, in particular between 31° and 33°. An angle γ, which the obliquely outwardly extending third contact wall sections 21 enclose, is preferably in a range from 90° to 110°, in particular between 95° and 100°.

[0060] In corresponding embodiments of the invention, a jet deflection angle of the steering path nozzle 13, ie the angle between the end positions BE 1 , BE 2 of the main jet direction HS 2 of the shower jet BS 2 , is in the range between 12° and 20°.

[0061] The following is based on the Figures 17 and 18 the functioning of this guideway nozzle 13 is explained. As soon as the effervescent fluid is supplied to the mouth area 14a, it exits therefrom and flows primarily in the longitudinal direction of the nozzle's longitudinal axis 13L to the outlet area 14c. Due to pressure, a small proportion of effervescent fluid flows into the annular chamber area 14b, as symbolized by flow arrows Ps. In the outlet area 14c, the effervescent fluid mainly adheres to one of the two jet system walls 16a, 16b, for example, first to the Figures 10 , 14 , 17 and 18 left blasting system wall 16a, as in Fig. 17 shown. The shower fluid is then deflected from the left jet system wall 16a to the right with its main jet direction HS 2 obliquely to the nozzle longitudinal axis 13 L or obliquely to a longitudinal axis of the jet outlet opening 15 and exits with this main jet direction HS 2 from the guide track nozzle 13 or its jet outlet opening 15, as in Fig. 17 shown.

[0062] The resulting shower fluid flow in the nozzle chamber 14 of the guideway nozzle 13 results in a negative pressure acting on the shower jet BS 2 in the nozzle chamber 14 in the direction of the opposite blasting system wall 16b, whereby the shower jet BS 2 is drawn onto this opposite blasting system wall 16b, in Fig. 17 symbolized by an associated pressure force arrow PD. This changes the shower jet BS 2 from its Fig. 17 shown course in the Fig. 18 shown course, in which it rests against the other blasting system wall 16b and from there with its main beam direction HS 2 into the Figures 14 , 17 and 18 is deflected to the left at an angle to the nozzle longitudinal axis 13 L.

[0063] Again, the negative pressure now acting in the opposite direction due to the shower fluid flow in the nozzle chamber 14 causes the shower jet BS 2 to be pulled towards the opposite blasting system wall, in this case towards the blasting system wall 16a, see the pressure force arrow PD with the opposite direction in Fig. 18 This causes the shower jet BS 2 to tilt back from its Fig. 18 shown course in the Fig. 17 shown history.

[0064] This back and forth tilting movement in the associated tilting or jet plane continues periodically, whereby the tilting frequency depends on the conditions of the steering path nozzle 13, in particular on the dimensioning of its mentioned components as well as on the fluid pressure or the flow rate of shower fluid.

[0065] As the embodiments shown and the further embodiments explained above make clear, the invention provides a toilet spray device which can be realized with relatively low manufacturing effort and which offers advantages over conventional toilet spray devices arranged on the toilet bowl side, in particular with regard to functionality and / or user comfort.
