Description

Technical Field

[0001] The present invention relates to a toilet spraying device which is arranged on the toilet bowl side in a functional position and includes a spraying bar having a spraying jet outlet nozzle which is configured to give a spraying jet with an upwardly directed jet direction component in the functional position. Background Art

[0002] This type of toilet spraying device has recently also been increasingly used in European countries as a hygienic and environmentally friendly alternative to traditional toilet paper or wet wipes for cleaning the buttocks / private areas. Currently, the toilet spraying device is arranged on the toilet bowl side in a functional position, i.e., it is located in or at a suitable position in the toilet bowl in order to fulfill its cleaning spraying function, also known as the toilet lid. This differentiates the currently considered toilet spraying device from other toilet spraying devices which are arranged in a suitable position outside the adjacent toilet bowl, such as a hand sprayer and a subordinate spray hose installed at the wall of the toilet space.

[0003] Toilet spraying devices of the currently considered type have been proposed in different ways, for example, see the utility model documents CN 205894217U, CN 203701234U, CN 203393820U and CN 201826380U. The toilet spraying devices disclosed therein include one or two spraying bars arranged side by side, which are preferably arranged to be retractable and extendable at the toilet bowl. To meet the different needs of users, especially the different needs of men on the one hand and women on the other hand, it is known to equip the spraying bar with two different spraying jet outlet nozzles or to arrange two spraying bars with different spraying jet outlet nozzles side by side at the toilet bowl.

[0004] A spraying jet generating device with a spraying jet outlet nozzle is disclosed in the published documents DE 10 2020 215 025 A1 and GB 2 202 764. The spraying jet generating device has a guide body that orbits in a nozzle chamber on a surrounding track. The guide body guides, i.e., deflects or directs, the supplied spraying fluid in a desired manner to provide a spraying jet with variable direction. Due to this functional principle, this type of nozzle is currently referred to as a guide body surrounding nozzle. The orbiting movement of the guide body can be carried out especially fluid pressure-driven, i.e., by the pressure of the spraying fluid introduced into the nozzle chamber. Summary of the Invention

[0005] As a technical problem, the present invention is based on providing a toilet spraying device of the type mentioned at the beginning, which can be realized with relatively low manufacturing costs and provides advantages over the above-mentioned prior art in one or more aspects, especially in terms of functionality and / or user comfort.

[0006] The present invention solves this problem by providing a toilet spraying device according to the present invention. Advantageous refinements of the present invention are described in the present invention, the statements of which are hereby made by express reference to parts of the description. This particularly also includes all embodiments which result from the combination of features which are defined by the present invention.

[0007] In the toilet spraying device according to the present invention, the spray jet outlet nozzle is a guide body surrounding nozzle which has a nozzle chamber, a jet outlet opening leading out of the nozzle chamber at the nozzle chamber wall portion above in the functional position, a surrounding track which is constructed on the lower nozzle chamber wall portion opposite to the upper nozzle chamber wall portion and surrounds the longitudinal axis of the guide body surrounding nozzle, and a guide body surrounding the surrounding track, wherein the guide body surrounding nozzle is provided for giving the spray jet in the main jet direction, which is inclined around its longitudinal axis of the nozzle.

[0008] The toilet spraying device according to the present invention thus comprises as the spray jet outlet nozzle a special guide body surrounding nozzle, the jet outlet opening of which leads out of the nozzle chamber at that nozzle chamber wall portion which is located above in the functional position of the toilet spraying device or the guide body surrounding nozzle, while the surrounding track is constructed for the guide body on the lower nozzle chamber wall portion opposite to the upper nozzle chamber wall portion. The design of the jet outlet opening on the one hand and of the surrounding track on the other hand can thus be realized in a desired manner independently of each other, the surrounding track does not limit the design feasibility of the jet outlet opening, and vice versa the jet outlet opening does not limit the design feasibility for the surrounding track, which extends around the longitudinal axis of the guide body surrounding nozzle as an annular closed track, for example as a circular or oval or elliptical track.

[0009] It has been shown that the realized guide body surrounding nozzle provides special advantages for giving the spray jet in an upwardly directed jet direction component via the jet outlet opening located above, as is desired for the current application situation of the toilet spraying device arranged at the toilet bowl in the functional position. In addition, by the surrounding of the surrounding body along the surrounding track, the desired jet characteristics for the spray jet are obtained, whereby the spray jet moves in a surrounding manner with its main jet direction inclined around the longitudinal axis of the nozzle, i.e. the spray jet moves in a surrounding manner around a generally conical jacket surface with its main jet direction, wherein the generally conical jacket which is currently usually understood can have any suitable cross-section which is not necessarily circular, in particular an oval cross-section. Here, the concept oval currently particularly also includes an elliptical shape, as is known per se, and the surrounding movement of the guide body can currently also be carried out in a fluid pressure driven manner, alternatively other conventional types of means for surrounding drive can be used for this purpose.

[0010] In an improved embodiment of the present invention, the jet outlet opening has an oval cross-section. This cross-sectional shape of the jet outlet opening has proven suitable for the current application in the case of a toilet spraying device, where it can in particular be an elliptical cross-section. In an alternative embodiment, the jet outlet opening can for example have a circular or polygonal cross-section.

[0011] In an improved embodiment of the present invention, the surrounding track has an oval shape. Similarly in this context, it is shown that this shape of the surrounding track very well meets the associated requirements for the current application in the case of a toilet spraying device, which relates to the desired jet characteristics of the spray jet provided by the guide body surrounding the nozzle. Alternatively, the surrounding track can for example have a circular shape.

[0012] In an embodiment of the present invention, the major semi-axis of the oval cross-section of the jet outlet opening and the major semi-axis of the oval shape of the surrounding track are parallel to each other. It is shown that this leads to suitable jet characteristics of the spray jet given by the guide body surrounding the nozzle for the corresponding application situation of the toilet spraying device.

[0013] In an embodiment of the present invention, the main jet direction circulates on an oval track, the major semi-axis of which is inclined with respect to the major semi-axis of the oval cross-section of the jet outlet opening and / or extends at an inclination angle with respect to the major semi-axis of the oval track of the surrounding track. It is also shown that this jet characteristic of the spray jet given by the guide body surrounding the nozzle is advantageous for buttock / private parts cleaning for the corresponding application or user requirements of the toilet spraying device.

[0014] In a further embodiment of the present invention, the inclination angle is in the range between 30° and 60°, in particular between 40° and 50°. The test results show that this range of inclination angles leads to optimal cleaning results and optimal user experience for the corresponding application situation of the toilet spraying device.

[0015] In an embodiment of the present invention, the major semi-axis of the oval cross-section of the jet outlet opening and / or the major semi-axis of the oval shape of the surrounding track are torsionally oriented around the nozzle longitudinal axis at a misalignment angle with respect to the longitudinal axis of the spray bar. Similarly here it is shown that this leads to suitable jet characteristics of the spray jet given by the guide body surrounding the nozzle for the corresponding application situation of the toilet spraying device.

[0016] In a further embodiment of the present invention, the misalignment angle is in the range between 30° and 60°, in particular between 40° and 50°. The test results also show for this case that this range of misalignment angles leads to optimal cleaning results and optimal user experience for the corresponding application situation of the toilet spraying device.

[0017] In an improved embodiment of the present invention, the longitudinal axis of the jet outlet opening is parallel to the longitudinal axis of the nozzle, and the guide body surrounds the nozzle and has a plurality of inlet openings which are arranged spaced apart from each other in the circumferential direction around the longitudinal axis of the nozzle, more precisely, in the region of the circumferential track in the lower nozzle chamber wall portion and lead into the nozzle chamber, wherein they extend with their longitudinal axes inclined to the longitudinal axis of the nozzle in the direction component along the circumferential direction of the circumferential track. It has surprisingly been shown that this configuration of the guide body surrounding the nozzle results in particularly good results with regard to the supply and guidance of the spray fluid for providing the desired spray jet, given the position of the inlet openings into the nozzle chamber. In an alternative embodiment, the inlet openings can be arranged, for example, between the upper and lower nozzle chamber wall portions at the side wall portion of the nozzle chamber.

[0018] In a design embodiment of the present invention, the cross-sectional area of each of the inlet openings is smaller than the cross-sectional area of the jet outlet opening. This dimensioning measure for the inlet openings relative to the jet outlet opening has proven to be very advantageous for the current application situation of the toilet spray device. In this and other embodiments of the present invention, the ratio of the entire inlet cross-section (i.e., the sum of the cross-sectional areas of one or more inlet openings) to the outlet cross-section (i.e., the sum of the cross-sectional areas of one or more jet outlet openings) is used to match the jet characteristics in accordance with the desired preset for the respective spray jet.

[0019] In an improved embodiment of the present invention, the guide body is a sphere that rolls or slides on the circumferential track, and its sphere diameter substantially corresponds to the maximum chamber height of the nozzle chamber in the region of the circumferential track. This is an advantageous implementation for the guide body. By having the maximum chamber height of the nozzle chamber substantially correspond to or only slightly exceed the sphere diameter of the sphere in order to enable free movement of the sphere in the nozzle chamber, the sphere is very reliably guided on its circumferential track by the adjacent nozzle chamber wall portions, which can contribute to the stability of the provided spray jet in its jet characteristics of periodically orbiting around the longitudinal axis of the nozzle. In an alternative embodiment, the guide body can be in any other form known per se from the prior art of guiding a body around a nozzle, and / or the maximum guide body diameter can be significantly smaller than the maximum nozzle chamber height in the region of the circumferential track in the respective case, for example only 70% or less of the maximum nozzle chamber height.

[0020] In an improved embodiment of the present invention, the toilet spraying device includes a second spray jet outlet nozzle, which is provided as a guiding track nozzle for giving a second spray jet with an upward-pointing jet direction component in a functional position and with a jet main direction, and which is driven by fluid pressure to periodically move in a jet plane in a flipping manner between two end positions. Here, the jet main direction extends inclined to the longitudinal axis of the guiding track nozzle on opposite sides of the longitudinal axis of the guiding track nozzle in the two end positions. The guiding track nozzle includes a fluid pressure-controlled nozzle chamber, a jet outlet opening led out from the nozzle chamber, and a chamber wall portion restricting its nozzle chamber, which serves as a guiding track for the second spray jet.

[0021] With this measure, the functionality and user comfort of the toilet spraying device are further improved. By providing two different spray jet outlet nozzles, two corresponding spray jets can be given with jet characteristics that can be different as needed. Depending on the configuration and expectation, the two spray jet outlet nozzles can be activated simultaneously or, alternatively, one or the other spray jet outlet nozzle can be activated. The presence of two types of moving jets enables optimization of the cleaning ability in the case of relatively low water consumption by means of the corresponding jet movements of the two spray jets.

[0022] The second spray jet outlet nozzle is particularly implemented as a guiding track nozzle in this case, which should now be understood as a nozzle that has a guiding track for guiding, i.e., leading or guiding, the spray fluid in order to form a second spray jet from the supplied spray fluid and to give it via a subordinate (or called associated, i.e., ) jet outlet opening. In this case, the jet characteristics include the periodic flipping movement of the spray jet in the jet plane with its jet main direction, where the switching or transformation is achieved by fluid pressure drive in the respective end positions, i.e., solely by the fluid pressure effect of the spray fluid located in the nozzle chamber. The nozzle chamber accordingly acts on the movement of the spray jet by fluid pressure control. The two end positions are in the jet plane in which the spray jet moves in a flipping manner with its jet main direction, more precisely, particularly inclined relative to it on opposite sides of the longitudinal axis of the guiding track nozzle. The guiding track for guiding the formation of the spray jet is provided by the chamber wall portion restricting the nozzle chamber, i.e., the corresponding part of the chamber wall portion serves as a guiding track for the spray fluid or the spray jet formed therefrom. The guiding track nozzle is thus sufficient without movable parts.

[0023] In an alternative embodiment, the toilet spraying device may include other types of second spray jet outlet nozzles, for example, it may be a nozzle surrounded by another guiding body. In addition, the toilet spraying device may have a third and, if possible, one or more additional spray jet outlet nozzles in the corresponding implementation.

[0024] In the design of the present invention, the guiding rail nozzle is arranged at the spray bar, or the toilet spraying device includes a second spray bar in addition to the spray bar that serves as the first spray bar, where the guiding rail nozzle is arranged. In the first case, the only spray bar is sufficient for the toilet spraying device to accommodate two spray jet outlet nozzles. In the latter-mentioned case, each of the two spray jet outlet nozzles is associated with its own spray bar. As required, it can be arranged such that the spray bars are arranged at the toilet bowl so as to be able to drive out and drive in independently of each other.

[0025] In a further design of the present invention, the functional position of the second spray bar is parallel beside the functional position of the first spray bar, that is, the longitudinal axes of the spray bars extend parallel in the functional position. This is a suitable positioning for most applications of the two spray bars. Here, it can be advantageous that the respective spray bar is only in the functional position during the activated operation and occupies a rest position during the non-activated period, in which it, for example, drives back or drives in relative to the functional position. In an alternative embodiment, the two spray bars can be arranged such that their longitudinal axes extend non-parallel to each other in their functional positions. In addition, the toilet spraying device can have a third and, if possible, one or more additional spray bars in the respective implementation.

[0026] In a further design of the present invention, the nozzle chamber of the guiding rail nozzle has an inlet-side nozzle-shaped part region, an annular chamber region surrounding the nozzle-shaped part region at the rear side, and an outlet region connected to the nozzle-shaped part region and the annular chamber region, which has two limiting jet abutment walls on opposite sides of the longitudinal axis of the guiding rail nozzle. This implementation of the nozzle chamber structurally advantageously enables the provision of a periodic flipping movement of the subordinate spray jet that is spontaneously driven by fluid pressure between its two end positions.

[0027] In a further design of the present invention, the jet abutment wall includes a first abutment wall region that respectively convexly widens the channel and a concave channel-narrowing second abutment wall region connected thereto in the direction of the subordinate jet outlet opening, in the case of forming an inclined outwardly extending first abutment wall section, a connected inclined inwardly extending second abutment wall section, and a final inclined outwardly extending third abutment wall section. Experimental studies have shown that this design of the jet abutment wall is particularly advantageous for providing optimal jet characteristics for the spray jet and its periodic reciprocating flipping movement, especially for the current situation of the toilet spraying device. Through the corresponding design of the different abutment wall sections, the spray jet to be provided can be set in a desired manner in view of its maximum outlet angle and in view of the switching frequency of its periodic movement between the two end positions.

[0028] In a further design of the present invention, the radius of curvature of the corresponding first abutment wall region is in the range of 0.3 mm to 0.6 mm, particularly in the range between 0.43 mm and 0.47 mm. In other designs of the present invention, the radius of curvature of the corresponding second abutment wall region is in the range of 1.2 mm to 1.6 mm, particularly in the range between 1.48 mm and 1.53 mm. In other designs of the present invention, the angle between the jets in the region of the corresponding second abutment section between the jets abutting against the wall is in the range of 100° to 120°, particularly in the range between 102° and 108°. In other designs of the present invention, the jet deflection angle of the guide rail nozzle is in the range between 12° and 20°. It is shown that with these special dimensional design measures (either alone or in combination), the characteristics of the given spray jet can be further optimized for the intended use purpose.

[0029] In another design of the present invention, the main jet direction of the spray jet of the guide body surrounding the nozzle orbits on an oval track, where the angle between the corresponding extreme positions of the main jet direction is preferably in the range of about 6° and about 20° at the reversal points (or turning points, i.e., Umkehrpunkten) of the oval track for the jet deflection parallel to the major semi-axis and preferably in the range of about 3° and about 10° for the jet deflection parallel to the minor semi-axis of the oval track. This dimensional design measure has proven to be suitable for most applications to obtain the desired cleaning effect.

[0030] It is shown that this value range results in optimal jet characteristics for the subordinate spray bar for the current application situation of the toilet spray device for the radius of curvature or tilt angle of the involved abutment wall region. Brief Description of the Drawings

[0052] Figure 1 shows an implementation of a toilet spray device according to the present invention, which includes a single spray bar 1 having a spray jet outlet nozzle in the form of a guiding body surrounding a nozzle 2. The toilet spray device is shown arranged on the toilet bowl side in a functional position, in which correspondingly the spray bar 1 is located at the toilet bowl TS in its functional position, as is known per se for a toilet spray device arranged on the toilet bowl side. The spray bar 1 can preferably be moved into or back to an initial position or a rest position from the shown functional position (in which it is located in or on the bowl - shaped space formed by the toilet bowl TS), as is also known per se. Thus, the spray bar 1 can travel or move in and out between the rest position and the functional position, for example, via a drive unit with a gear mechanism. Preferably, the spray bar is arranged in a region outside the bowl - shaped space to the greatest extent in its rest position, in particular lowered or retracted into the bowl body of the toilet bowl TS surrounding the bowl - shaped space. Figure 1

[0053] Figures 4 to 9 The guiding body surrounding the nozzle 2 includes a nozzle chamber 3 and a jet outlet opening 5, which leads out from the nozzle chamber 3 at the upper, i.e., upper - side nozzle chamber wall portion 4 in the functional position of the spray bar 1, where the nozzle chamber wall portion 4 limits the nozzle chamber 3 on the upper side, as can be seen in particular from As can also be recognized there, the guiding body surrounding the nozzle 2 further includes a surrounding track 7, which surrounds the longitudinal axis 2 of the guiding body surrounding the nozzle 2 , that is, extends around it, and a guiding body 8 surrounding on the surrounding track 7. The surrounding track 7 is constructed on the lower nozzle chamber wall portion 6 opposite to the upper nozzle chamber wall portion 4.

[0054] Figure 11 The guiding body surrounding the nozzle 2 is designed to give a spray jet BS with a jet direction component K pointing upward in the functional position of the spray bar 1 S where the main jet direction HS of the spray jet BS is inclined with respect to the nozzle longitudinal axis 2 L around which it is surrounded. This jet behavior of the spray jet BS is illustrated in Figure 12 , see the surrounding arrow P serving as an illustration here U ​。 Figure 12 shows a schematic side view of the spray jet BS surrounded by the guide body of the spray bar 1 around the nozzle 2 about the nozzle longitudinal axis 2 L surrounded. As can be recognized in particular from Figure 11 it, the spray jet BS thus moves in a circular motion around a generally conical jacket-shaped surface with its jet main direction HS.

[0055] In an advantageous embodiment, the corresponding spray bar with the guide body surrounding the nozzle 2, such as the spray bar 1 or the spray bar 1 1 and 1 2 is arranged in the area behind the toilet bowl TS in such a way that the spray jet BS is given by the guide body surrounding the nozzle 2 at an angle of about 40° to about 65°, in particular between about 50° and about 55°, obliquely upwards in front of the vertical line.

[0056] Figure 2 shows a toilet spray device according to the invention in an embodiment, which embodiment has a spray bar 1 equipped with two guide rail nozzles: the first spray bar 1 1 and the second spray bar 1 2 which are preferably brought into their respective functional positions at the toilet bowl independently of each other according to Figure 1 the type of toilet bowl TS, for example by moving out of an initial or rest position in a similar manner as explained above for Figure 1 the spray bar 2. In the Figure 2 embodiment, the functional position of the second spray bar 1 2 is parallel beside the functional position of the first spray bar 1 1 and one spray bar preferably remains in its initial / rest position when the other spray bar is in its functional position. During the operation of the toilet spray device according to Figure 2 the spray bar 1 1 is preferably used for cleaning the female buttocks and the female intimate area, and the spray bar 1 2 is preferably used for cleaning the male buttocks.

[0057] In an advantageous embodiment, the jet outlet opening 5 of the guide body surrounding the nozzle 2 has an oval cross-section, in particular an elliptical cross-section. This is the case in the example shown, Figure 7 the view shows the corresponding oval or elliptical part of the cross-section of the jet outlet opening 5.

[0058] In an advantageous embodiment, the surrounding track 7 has an oval shape, in particular an elliptical shape, as in the example shown, as can be seen in Figure 9 .

[0059] In a corresponding implementation, as in the example shown, the major semi-axis 5 of the oval cross-section of the jet outlet opening 5 G (the diameter extending in the left-right direction of the jet outlet opening 5 in Figure 7 ) and the major semi-axis 7 of the oval shape of the circumferential track 7 G (the oval track diameter in the left-right direction in Figure 9 ) are parallel to each other. Correspondingly, 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 circumferential track 7 are also parallel to each other, the corresponding diameters in the up-down direction in Figure 7 and 9 .

[0060] In a corresponding implementation where the guide body surrounds the nozzle 2, the main jet direction HS of the spray jet BS given by the guide body surrounding the nozzle 2 is circumferentially around the oval track 9 as in the example shown, and its major semi-axis 9 G is inclined to the major semi-axis 5 of the oval cross-section of the jet outlet opening 5 G and / or is inclined to the major semi-axis 7 of the oval shape of the circumferential track 7 at an inclination angle α G extending. Both characteristics are achieved in the example shown.

[0061] Figure 13 Shows the impact diagram of the spray jet BS for the guide body surrounding the nozzle 2 in a plane perpendicular to the nozzle longitudinal axis 2 L , where in this embodiment, the coincident directions of the major semi-axes 5 G , 7 G of the jet outlet opening 5 and the circumferential track 7 are called the x-direction and the direction perpendicular to this is called the y-direction. The x-direction is preferably parallel to the longitudinal axis 1 of the spray bar 1 L or is inclined to it at an acute angle. As can be seen therefrom, the impact maximum, i.e., the maximum jet intensity of the spray jet BS, is in an oval or elliptical annular region. In other words, the main jet direction HS of the spray jet BS is circumferentially around the oval track 9 with the major semi-axis 9 G and the minor semi-axis 9 perpendicular thereto K . The angular orientation of the oval track 9 of the impact characteristics of the spray jet BS changes with the changing distance between the spray jet BS and the guide body surrounding the nozzle 2, i.e., the inclination angle α changes, for example, with the changing distance.

[0062] When desired, the major semi-axis 9 of the oval track 9 GFor the main jet direction HS of the spray jet BS, in the theoretical spacing, which can be preset, between the impact surface and the guide body surrounding the jet outlet opening 5 of the nozzle 2 or the spray bar 1, it extends parallel to the longitudinal axis of the toilet bowl TS and thus generally also parallel to the longitudinal axis 1 of the spray bar 1 L extends, and thus the jet outlet opening 5 and / or the major semi-axis 5 of the circumferential track 7 are oriented at the spray bar 1 in such an angular position that G ,7 G it is inclined at a correspondingly pre-determined value of the offset angle α1 to the longitudinal axis 1 of the spray bar 1 L extends.

[0063] In Figure 20 an exemplary illustration related thereto shows the case in which the major semi-axes 5 G ,7 G of the jet outlet opening 5 and the circumferential track 7 are each inclined at the offset angle α1 relative to the longitudinal axis 1 of the spray bar 1 L about the longitudinal axis 2 of the guide body surrounding nozzle 2 L in a twisted orientation, where in this case the offset angle α1 is about 45° and it is shown that then in the theoretical spacing, preset between the impact surface of the spray jet BS and the spray bar 1, the oval track 9 for the main jet direction HS of the spray jet BS is oriented with its major semi-axis 9 G substantially parallel to the longitudinal axis 1 of the spray bar L oriented. Similarly, it can also be recognized in Figure 2 that the outlet oval of the guide body surrounding nozzle 2 is oriented with its major semi-axis inclined to the longitudinal axis 1 of the spray bar L oriented. Generally, the offset angle α1, like the inclination angle α, preferably lies in the range between about 0° and about 60°, in particular between about 40° and about 50°.

[0064] For the secondary jet deflection angle of the spray jet BS (i.e., the angle between the corresponding extreme positions at the reversal points of the oval or elliptical annular region), it preferably lies in the range between about 6° and about 20° for jet deflections parallel to the major semi-axis 9 G and preferably lies in the range between about 3° and about 10° for jet deflections parallel to the minor semi-axis 9 K .

[0065] This jet characteristic of the spray jet BS of the guide body surrounding nozzle 2 results from the guiding function of the guide body 8 surrounding the circumferential track 7. The supplied spray fluid abuts against the guide body 8 and is thus deflected towards this side relative to the nozzle longitudinal axis 2 L and escapes as a spray jet BS with a jet main direction HS deflected accordingly from the direction of the nozzle longitudinal axis 2 L from the jet outlet opening 5. When in Figure 11When the middle guide body 8 is located on the right side of the nozzle chamber 3, the main jet direction HS of the spray jet BS following the dashed line is thus obtained. When the guide body 8 is Figure 11 located on the left side of the nozzle chamber 3, it follows the main jet direction HS of the solid line. In other words, the circumferential movement of the guide body 8 on the circumferential track 8 causes the main jet direction HS of the spray jet BS to surround the nozzle longitudinal axis 2 L .

[0066] In an advantageous embodiment, the longitudinal axis 5 of the jet outlet opening 5 L is parallel to the nozzle longitudinal axis 2 L , and the guide body surrounds the nozzle 2 with a plurality of inlet openings 10, as in the illustrated example. The inlet openings 10 are arranged in the region of the circumferential track 7 in the lower nozzle chamber wall portion 6 at circumferential sides around the nozzle longitudinal axis 2 L spaced apart from each other. As can be seen from Figure 9 . Here, the inlet openings 10 open into the nozzle chamber 3 in such a way that their longitudinal axes, which are inclined to the nozzle longitudinal axis 2 L , extend with a direction component in the circumferential direction of the circumferential track 7.

[0067] In the illustrated example, the inlet openings 10 are formed by the outlets of subordinate, substantially straight, inclined channels 11, which lead out from one of the distribution chambers 12 located in front of the nozzle chamber 3, as can be recognized from Figure 5 , 6 and 8. Via the inlet openings 10, the spray fluid thus enters the nozzle chamber 3 in the circumferential direction of the circumferential track 7 with a corresponding direction component and drives the guide body 8 to its circumferential movement on the circumferential track 7 with its fluid pressure.

[0068] In the corresponding embodiment, the cross-sectional area of each of the inlet openings 10 is smaller than the cross-sectional area of the jet outlet opening 5 itself. This is the case in the illustrated example.

[0069] In an advantageous embodiment, the guide body 8, as in the illustrated example, is a sphere that rolls and / or slides on the circumferential track 7, and its sphere diameter substantially corresponds to the maximum chamber height of the nozzle chamber 3 in the region of the circumferential track 7. In other words, in this case, the height of the nozzle chamber 3 is only so much larger than the diameter of the guide body 8 that an unhindered circumferential movement of the guide body 8 on the circumferential track 7 is achieved. With only a slightly higher nozzle chamber 3, the guide body 8 is kept as much as possible guided through the adjacent nozzle chamber walls during its circumferential movement. In particular, the upper nozzle chamber wall portion 4 restricts the lifting movement of the guide body 8 from the lower nozzle chamber wall portion 6, where the circumferential track 7 is constructed, and the lifting movement is caused by the spray fluid supplied at the lower nozzle chamber wall portion 6 via the inlet openings 10.

[0070] In an advantageous embodiment, the toilet spraying device according to the invention comprises a second spraying jet outlet nozzle, which is designed as a guide track nozzle 13 for a jet direction component K pointing upwards in the functional position of the toilet spraying device S2 and with a jet main direction HS 2 giving a second spraying jet BS 2 , which is driven by fluid pressure to move periodically and reciprocally in the jet plane between two end positions BE 1 , BE 2 .

[0071] Such a guide track nozzle 13 is provided in the spraying rod 1 according to Figure 1 and 3 to 18 and in the first spraying rod 1 Figure 2 more precisely along the longitudinal direction of the spraying rod 1 with a spacing from the guide body surrounding nozzle 2 closer to the free end of the spraying rod, as can be seen for example from 1 . Figures 1 to 5 Visible Figure 4 , 5 , 10, 14, 17 and 18 each show the guide track nozzle 13 in a section parallel to the jet plane Figure 14 , 17 and 18 show the second spraying jet BS 1 , BE 2 in this end position BE 2 . As can be seen therefrom, in the two end positions BE 1 , BE 2 the jet main direction HS 2 of the second spraying jet BS 2 extends on opposite sides of the longitudinal axis 13 L of the guide track nozzle 13, more precisely each inclined to this guide track nozzle longitudinal axis 13 L .

[0072] The guide track nozzle 13 comprises a fluid pressure-controlled nozzle chamber 14, a jet outlet opening 15 leading out of the nozzle chamber 14 and a chamber wall part 16 limiting the nozzle chamber 14, which serves as a guide track for the second spraying jet BS 2 . This feature of the guide track nozzle 13 can be recognized for example in Figure 5 , 10 , 14, 17 and 18 Figure 15 shows in a schematic side view the second spraying jet BS 1 , BE 2 reciprocating in the jet plane between two end positions BE 2, as it is given by the guiding track nozzle 13 during operation. Figure 16 Similar to Figure 13 The impact similar to that shows as follows and how the spray jet BS 2 The region of the maximum jet intensity of is the corresponding linear impact region, which extends substantially in the x-direction, i.e., substantially parallel to the longitudinal axis 1 of the spray bar L . The subordinate jet deflection angle, i.e., at the two end positions BE 1 , BE 2 The angle between is preferably in the range between about 12° and about 20°.

[0073] In an advantageous embodiment, the corresponding spray bar comprising the guiding track nozzle 13, such as spray bar 1 or spray bar 1 1 , is arranged in the rear region of the toilet bowl TS such that the spray jet BS 2 is given by the guiding track nozzle 2 at an angle of about 40° to about 65°, especially between about 55° and about 60°, inclined forward and upward relative to the vertical line.

[0074] In the corresponding embodiment, the guiding track nozzle 13 is arranged on the same spray bar 1 as the guiding body surrounding nozzle 2. This is the case in Figure 1 spray bar 1 of Figure 2 and the first spray bar 1 of 1 . Alternatively, the guiding track nozzle 13 can be arranged on a spray bar 1 different from the guiding body surrounding nozzle 2. This is the case in Figure 2 a variant of the example of 1 in which the first spray bar 1 1 , 1 2 only has the guiding track nozzle 13 and does not additionally have the guiding body surrounding nozzle 2. As already mentioned above, in the case of multiple spray bars, such as the first and second spray bars 1

[0075] Generally, the guiding body surrounding nozzle 2 is first suitable for cleaning the anus, while the guiding track nozzle 13 is preferably suitable for cleaning the female intimate area.

[0076] In an advantageous embodiment, the nozzle chamber 3 of the guiding track nozzle 2 comprises, as in the shown example, an inlet-side nozzle-shaped region 14a, an annular chamber region 14b surrounding the nozzle-shaped region 14a at the rear side, and an outlet region 14c connected to the nozzle-shaped region 14a and the annular chamber region 14b in the flow direction of the spray fluid, wherein the outlet region 14c has a longitudinal axis 13 of the guiding track nozzle LTwo restricting jets on opposite sides thereof bear against walls 16a, 16b, as can be recognized in particular in Figure 10 , 14 , 17 and 18.

[0077] In an advantageous embodiment, the jets bear against walls 16a, 16b which, as in the example shown, each have a convex first wall region 17 which widens the channel and a concave second wall region 18 which narrows the channel and is connected thereto in the direction of the secondary jet outlet opening 15. This design of the wall regions 17, 18 accordingly provides a first wall section 19 which extends obliquely outwards, a connected second wall section 20 which extends obliquely inwards, and a final third wall section 21 which extends obliquely outwards. The associated dimensional design measures are illustrated for possible embodiments in Figure 19 .

[0078] As shown in Figure 19 , in an advantageous embodiment the radius of curvature R1 of the corresponding first wall region 17 (in particular the upstream part which arches forward drum-shapedly towards the longitudinal axis 13 L ) lies in the range between 0.3 mm and 0.6 mm, in particular between 0.43 mm and 0.47 mm. Furthermore, in an advantageous embodiment, the radius of curvature R2 of the corresponding second wall region 18 (in particular the upstream part which arches away drum-shapedly from the longitudinal axis 13 L ) lies in the range between 1.2 mm and 1.6 mm, in particular between 1.48 mm and 1.53 mm. Additionally, in an advantageous embodiment, the angle β of the corresponding second wall section 18 (in particular the angle between the downstream wall sections 20 which extend obliquely inwards) lies in the range between 100° and 120°, in particular between 102° and 108°. The radius of curvature R3 of the section which arches forward drum-shapedly towards the longitudinal axis 13 L directly in front of the obliquely outwards extending third wall section 21 preferably lies in the range between 0.3 mm and 0.9 mm, in particular between 0.7 mm and 0.75 mm. The angle δ (at which the jets bear against walls 16a, 16b extend towards each other in front of the convex first wall region 17 which widens the channel) preferably lies in the range between 30° and 35°, in particular between 31° and 33°. The angle γ enclosed by the obliquely outwards extending third wall section 21 preferably lies in the range between 90° and 110°, in particular between 95° and 100°.

[0079] In a corresponding embodiment of the invention, the jet deflection angle of the guide rail nozzle 13, i.e. the main jet direction HS of the spray jet BS 2 and the end position BE of 2 the jet1 , BE 2 The angle between is in the range between 12° and 20°.

[0080] Subsequently, according to Figure 17 and 18 , the principle of operation of the deflecting rail nozzle 13 is explained. Once the spraying fluid is supplied to the nozzle body region 14a, it exits the nozzle body region and flows mainly in the longitudinal direction of the nozzle longitudinal axis 13 L to the outlet region 14c. Pressure-determined, a lower share of the spraying fluid flows into the annular cavity region 14b, as indicated by the flow arrow P S symbolically. In the outlet region 14c, the spraying fluid mainly abuts against one of the two jet abutment walls 16a, 16b, for example first against Figure 10 , 14 , 17 and 18 at the left jet abutment wall 16a, as Figure 17 shown in. The spraying fluid is then deflected by the left jet abutment wall 16a to the right in its jet main direction HS 2 inclined with respect to the nozzle longitudinal axis 13 L or inclined with respect to the longitudinal axis of the jet outlet opening 15 and exits from the deflecting rail nozzle 13 or its jet outlet opening 15 in this jet main direction HS 2 , as presented in Figure 17 .

[0081] The resulting flow of the spraying fluid in the nozzle chamber 14 of the deflecting rail nozzle 13 causes a negative pressure acting on the spray jet BS 2 in the direction of the opposite jet abutment wall 16b in the nozzle chamber 14, whereby it pulls the spray jet BS 2 onto this opposite jet abutment wall 16b, symbolically indicated by the subordinate pressure arrow P Figure 17 in. Thereby, the spray jet BS D is transformed from its path shown in 2 to the path shown in Figure 17 , in which it abuts against the other jet abutment wall 16b and is deflected by it in its jet main direction HS Figure 18 in 2 in Figure 14 , 17 and 18 inclined to the left with respect to the nozzle longitudinal axis 13 L .

[0082] Then the negative pressure acting in the opposite direction at this time again causes, through the flow of the spraying fluid in the nozzle chamber 14, that the spray jet BS 2 is pulled towards the opposite jet abutment wall, in this case towards the jet abutment wall 16a, see inFigure 18 with pressure arrows P in opposite directions D . Thus, the spray jet BS 2 is again caused by it Figure 18 to flip back to the path shown in Figure 17 the path shown in.

[0083] This reciprocating flipping motion in the subordinate flipping or jet plane continues periodically, where the flipping frequency depends on the situation of the guide rail nozzle 13, in particular on the dimensional design of the mentioned components and the fluid pressure or flow rate at the spray fluid.

[0084] As made clear by the illustrated and previously explained embodiments, the present invention provides a toilet spray device for use, which can be realized with relatively low manufacturing costs and offers advantages over conventionally arranged toilet spray devices on the side of the toilet bowl, particularly in terms of functionality and / or user comfort.
