Description

Technical Field

[0001] The invention relates to a toilet shower device which is arranged on the toilet bowl side in a functional position and comprises a shower wand having a shower jet outlet nozzle which is designed to emit a shower jet with a jet direction component which points upward in the functional position. Background Art

[0002] This type of toilet spray device has recently also been increasingly used in European countries as a hygienic and environmentally friendly alternative to conventional toilet paper or wet wipes for cleaning the buttocks / private area. Currently, the toilet spray device is arranged in a functional position on the toilet bowl side, that is, it is located in a suitable position in or at the toilet bowl, also called toilet cover, for its cleaning spray function. This distinguishes the toilet spray device currently under consideration from other toilet spray devices, which are arranged in a suitable position outside the toilet bowl adjacent thereto, for example as a hand sprayer installed at the wall of the toilet space and a subordinate spray hose.

[0003] Toilet spray devices of the type currently under consideration have been proposed in different ways, for example, see utility model documents CN 205894217U, CN 203701234U, CN 203393820U and CN 201826380U. The toilet spray devices disclosed therein comprise one or two spray bars arranged side by side, which are preferably arranged to be able to be moved out and in at the toilet bowl. In order to meet the different needs of users, in particular the different needs of men on the one hand and women on the other hand, it is known to equip the spray bar with two different spray jet outlet nozzles or to arrange two spray bars with different spray jet outlet nozzles side by side at the toilet bowl.

[0004] A spray jet generating device with a spray jet outlet nozzle is disclosed in the publications DE 10 2020 215 025 A1 and GB 2 202 764, which has a guide body that surrounds in a nozzle chamber on a circular track, and which guides, i.e. deflects or guides the supplied spray fluid in a desired manner to provide a spray jet with variable direction. Due to this functional principle, this type of nozzle is currently referred to as a guide body surround nozzle. The surrounding movement of the guide body can be carried out in particular by fluid pressure drive, i.e. by the pressure of the spray fluid introduced into the nozzle chamber. Summary of the invention

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

[0006] The present invention solves this problem by providing a toilet shower device according to the present invention. Advantageous improvements of the present invention are described in the present invention, which are hereby made by explicit reference to the components of the description. This also includes in particular all embodiments, which result from the feature combination, which are defined by the present invention.

[0007] In the toilet spray device according to the present invention, the spray jet outlet nozzle is a guide body surround nozzle, which has a nozzle chamber, a jet outlet opening leading from the nozzle chamber wall above the nozzle chamber in the functional position, a surround track constructed on the lower nozzle chamber wall opposite to the upper nozzle chamber wall and surrounding the longitudinal axis of the guide body surround nozzle, and a guide body surrounding on the surround track, wherein the guide body surround nozzle is set up to deliver a spray jet in the main direction of the jet, which surrounds it obliquely to the longitudinal axis of the nozzle.

[0008] The toilet shower device according to the invention thus comprises as a shower jet outlet nozzle a special guide body surround nozzle, whose jet outlet opening leads out of the nozzle chamber at that nozzle chamber wall, which in the functional position of the toilet shower device or the guide body surround nozzle is located at the top, while the surround track is constructed for the guide body on the lower nozzle chamber wall opposite to the upper nozzle chamber wall. The design of the jet outlet opening on the one hand and the surround track on the other hand can thus be realized independently of each other in the desired manner, the surround track not restricting the design possibilities of the jet outlet opening and conversely the jet outlet opening not restricting the design possibilities for the surround track, which extends as an annular closed track around the longitudinal axis of the guide body surround nozzle, for example as a circular or oval or elliptical track.

[0009] It is shown that the guide body surrounding the nozzle in a present manner offers the particular advantage of providing a spray jet with an upwardly directed jet direction component via a jet outlet opening located above, as is desired for the current application of a toilet shower device arranged on a toilet bowl in a functional position. The desired jet characteristics for the spray jet are also obtained by the surrounding of the surrounding body along a surrounding path, whereby the spray jet surrounds it with its jet main direction inclined to the longitudinal axis of the nozzle, i.e. the spray jet moves around with its jet main direction around a generally conical outer shell surface, wherein the conical outer shell that is currently generally understood can be any suitable cross-section that is not necessarily circular, in particular an oval cross-section. In this case, the concept oval currently also includes, in particular, elliptical shapes, as is known per se, and the surrounding movement of the guide body can also be carried out in a fluid pressure-driven manner, alternatively for this purpose another conventional type of surrounding drive can be used.

[0010] In a refinement of the invention, the jet outlet opening has an oval cross section. This cross-sectional shape of the jet outlet opening has proven to be suitable for current applications in the context of toilet showers, wherein it can be in particular an elliptical cross section. In an alternative embodiment, the jet outlet opening can, for example, have a circular or polygonal cross section.

[0011] In a refinement of the invention, the orbital track has an oval shape. It is also shown in this connection that this shape of the orbital track is very suitable for current applications in the case of toilet shower devices, with regard to the desired jet characteristics of the spray jet provided by the guide body surrounding the nozzle. Alternatively, the orbital track can, for example, have a circular shape.

[0012] In the design of the present invention, the major half axis of the oval cross section of the jet outlet opening and the major half axis of the oval shape of the orbit 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 of the toilet spray device.

[0013] In the design of the present invention, the main direction of the jet is circling on an oval track, the major axis of which is inclined to the major axis of the oval cross section of the jet outlet opening and / or extends at an inclination angle to the major axis of the oval track that circumscribes the track. It is also shown that for the corresponding application or user needs of the toilet spray device, this jet characteristic of the spray jet given by the guide body surrounding the nozzle is advantageous for buttocks / private cleaning.

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

[0015] In the design of the invention, the major half axis of the oval cross section of the jet outlet opening and / or the major half axis of the oval shape of the orbit is twisted and oriented around the longitudinal axis of the nozzle at an offset angle relative to the longitudinal axis of the spray rod. It is also shown here that this leads to suitable jet characteristics of the spray jet given by the guide body surrounding the nozzle for the corresponding application of the toilet spray device.

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

[0017] In a further development of the invention, the longitudinal axis of the jet outlet opening is parallel to the longitudinal axis of the nozzle, and the guide body surrounding the nozzle has a plurality of inlet openings, which are arranged spaced apart from each other on the circumferential side around the longitudinal axis of the nozzle, more precisely in the lower nozzle chamber wall in the region of the surrounding track, and open into the nozzle chamber, wherein they extend with their longitudinal axis inclined to the longitudinal axis of the nozzle with a direction component in the circumferential direction of the surrounding track. Surprisingly, it has been found that this configuration of the guide body surrounding the nozzle, due to the position of the inlet openings into the nozzle chamber, leads to particularly good results with regard to the supply and guidance of the spray fluid in order to provide the desired spray jet. In an alternative embodiment, the inlet opening can be arranged between the upper and lower nozzle chamber wall, for example, at the side wall of the nozzle chamber.

[0018] In the embodiment of the 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 opening relative to the jet outlet opening has proven to be very advantageous for current applications of toilet shower devices. In this and other embodiments of the invention, the ratio of the total 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 for this purpose to adapt the jet characteristics in accordance with the desired preset for the respective spray jet.

[0019] In a further development of the invention, the guide body is a ball rolling or sliding on a circular track, the ball diameter of which corresponds substantially to the maximum cavity height of the nozzle cavity in the region of the circular track. This is an advantageous implementation for the guide body. By having the maximum cavity height of the nozzle cavity substantially corresponding to or only slightly greater than the ball diameter of the ball, in order to achieve free movement of the ball in the nozzle cavity, the ball is very reliably guided on its circular track by the adjacent nozzle cavity wall, which can be beneficial to the stability of the spray jet provided in its jet characteristics that periodically rotate around the longitudinal axis of the nozzle. In alternative embodiments, the guide body can be in any other form known per se from conventional guide body surrounding nozzles, and / or the maximum guide body diameter can be significantly smaller in the corresponding case than the maximum nozzle cavity height in the region of the circular track, for example only 70% or less of the maximum nozzle cavity height.

[0020] In an improved solution of the present invention, the toilet spray device includes a second spray jet outlet nozzle, which is set up as a guide rail nozzle for delivering a second spray jet with a jet direction component pointing upward in the functional position and with a jet main direction, and which is driven by fluid pressure to periodically move in a flipping manner in the jet plane between two end positions. Here, the jet main direction extends in the two end positions on opposite sides of the longitudinal axis of the guide rail nozzle, respectively, obliquely to the longitudinal axis of the guide rail nozzle. The guide rail nozzle includes a fluid pressure-controlled nozzle chamber, a jet outlet opening leading from the nozzle chamber, and a chamber wall portion that limits its nozzle chamber, which serves as a guide rail for the second spray jet.

[0021] With this measure, the functionality and user comfort of the toilet shower device are further increased by providing two different shower jet outlet nozzles, through which two shower jets can be emitted with different jet characteristics as required. Depending on the configuration and the desired, the two shower jet outlet nozzles can be activated simultaneously or one or the other shower jet outlet nozzle can be activated alternatively. The presence of two moving jet types enables an optimization of the cleaning capacity with relatively low water consumption by means of the corresponding jet movement of the two shower jets.

[0022] The second spray jet outlet nozzle is in this case embodied in particular as a guide rail nozzle, which is to be understood herein as a nozzle which has a guide rail for guiding, i.e. guiding or directing the spray fluid, so that the second spray jet is formed from the supplied spray fluid and with corresponding jet properties via a subordinate (or associated, i.e. ) jet outlet opening. In this case, the jet characteristics include a periodic flipping movement of the spray jet with its jet main direction in the jet plane, wherein the switching or conversion is achieved in a fluid pressure-driven manner in the corresponding end positions, i.e. solely by the fluid pressure effect of the spray fluid located in the nozzle chamber. The nozzle chamber acts on the movement of the spray jet accordingly by fluid pressure control. The two end positions are in the jet plane, in which the spray jet flips with its jet main direction, more precisely, in particular on opposite sides of the longitudinal axis of the guide track nozzle and is respectively inclined relative to it. The guide track for guiding the formation of the spray jet is provided by the cavity wall portion that limits the nozzle cavity, i.e. the corresponding part of the cavity wall portion serves as a guide track for the spray fluid or the spray jet formed thereby. The guide track nozzle is therefore sufficient without a movable part.

[0023] In alternative embodiments, the toilet spray device can comprise the second spray jet outlet nozzle of other types, for example it can be another guide body surrounding the nozzle.In addition, the toilet spray device can have the third and if possible also one or more other spray jet outlet nozzles in corresponding implementations.

[0024] In the embodiment of the invention, the guide rail nozzle is arranged at the spray rod, or the toilet spray device comprises a second spray rod in addition to the spray rod as the first spray rod, at which the guide rail nozzle is arranged. In the first case, a single spray rod is sufficient for the toilet spray device to accommodate two spray jet outlet nozzles. In the latter case, each of the two spray jet outlet nozzles is associated with its own spray rod. If necessary, it can be provided that the spray rods can be moved out and in independently of each other at the toilet bowl.

[0025] In a further embodiment of the invention, the functional position of the second spray rod is located parallel to the functional position of the first spray rod, i.e. the longitudinal axes of the spray rods extend in parallel in the functional position. This is a suitable positioning of the two spray rods for most applications. It can be advantageous here that the respective spray rod is located in the functional position only in the active operation and occupies a static position during the inactive time period, in which it moves back or in relative to the functional position, for example. In an alternative embodiment, the two spray rods can be arranged so that they extend in their functional position with longitudinal axes that are not parallel to each other. In addition, the toilet spray device can have a third and, if possible, one or more further spray rods in a corresponding embodiment.

[0026] In another embodiment of the invention, the nozzle chamber of the guide rail nozzle has a mouth-shaped part area on the inlet side, an annular chamber area surrounding the mouth-shaped part area at the rear side, and an outlet area connected to the mouth-shaped part area and the annular chamber area, which has two limiting jet contact walls on opposite sides of the longitudinal axis of the guide rail nozzle. This embodiment of the nozzle chamber realizes a spontaneous, fluid pressure-driven, periodic tumbling movement of the subordinate spray jet between its two end positions in a structurally advantageous manner.

[0027] In a further design of the present invention, the jet contact wall comprises a first contact wall area which has a convex shape and acts as a channel widening, and a second contact wall area which has a concave shape and acts as a channel narrowing and is connected thereto in the direction of the subordinate jet outlet opening, forming a first contact wall section extending obliquely outward, a connected second contact wall section extending obliquely inward, and a final third contact wall section extending obliquely outward. Experimental studies have shown that this design of the jet contact wall is particularly advantageous for providing optimal jet characteristics for the spray jet and its periodic flipping reciprocating motion, in particular for the current situation of toilet spray devices. By correspondingly designing the different contact wall sections, the spray jet to be provided can be set in a desired manner with respect to its maximum outlet angle and with respect to the switching frequency of its periodic motion between the two end positions.

[0028] In a further embodiment of the invention, the radius of curvature of the corresponding first area in contact with the wall is in the range of 0.3 mm to 0.6 mm, in particular in the range between 0.43 mm and 0.47 mm. In other embodiments of the invention, the radius of curvature of the corresponding second area in contact with the wall is in the range of 1.2 mm to 1.6 mm, in particular in the range between 1.48 mm and 1.53 mm. In other embodiments of the invention, the angle between the jets in contact with the wall in the region of the corresponding second wall section is in the range of 100° to 120°, in particular in the range between 102° and 108°. In other embodiments of the invention, the jet deflection angle of the guide rail nozzle is in the range between 12° and 20°. It is shown that, by means of these special dimensional design measures (whether individually or in combination), the characteristics of the given spray jet can be further optimized for the intended use.

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

[0030] It has been shown that this value range for the relevant radius of curvature or angle of inclination of the contact wall region leads to an optimal jet characteristic of the associated spray wand for the present application of the toilet spray device. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Figure 1 The embodiment of the toilet spray device according to the invention is shown, which comprises a single spray wand 1 having a spray jet outlet nozzle in the form of a guide body surrounding the nozzle 2. Figure 1 1 is shown arranged on the toilet bowl side in a functional position, wherein correspondingly the spray wand 1 is also located on the toilet bowl TS in its functional position, as is known per se for toilet shower devices arranged on the toilet bowl side. The spray wand 1 can preferably be moved into or back into an initial position or rest position from the functional position shown, in which it is located in or on the bowl-shaped space formed by the toilet bowl TS, as is also known per se. In this way, the spray wand 1 can be moved or moved out and in between the rest position and the functional position, for example via a drive unit with a gear transmission. Preferably, in its rest position, the spray wand is arranged for the most part in an area outside the bowl-shaped space, in particular lowered or moved back into a bowl-shaped body of the toilet bowl TS surrounding the bowl-shaped space.

[0053] The guide body surrounds the nozzle 2 and comprises a nozzle chamber 3 and a jet outlet opening 5, which in the functional position of the spray bar 1 is led out of the nozzle chamber 3 at the upper, i.e. upper, nozzle chamber wall 4, wherein the nozzle chamber wall 4 delimits the nozzle chamber 3 at the top, such as in particular from Figures 4 to 9 As can also be seen there, the guide body surrounding the nozzle 2 also includes a surrounding track 7 which surrounds the longitudinal axis 2 of the guide body surrounding the nozzle 2. L , namely a guide body 8 extending around it and circumscribing on a circumferential track 7. The circumferential track 7 is constructed on a lower nozzle chamber wall portion 6 that is opposite to the upper nozzle chamber wall portion 4.

[0054] The guide body is designed around the nozzle 2 for a jet direction component K directed upwards in the functional position of the spray bar 1. S A spray jet BS is produced, wherein the jet main direction HS of the spray jet BS is inclined to the nozzle longitudinal axis 2 L The jet behavior of the spray jet BS is Fig.11 In the diagram, see the encircling arrow P for illustration purposes U. Fig.12 The nozzle 2 is shown surrounded by the guide body of the spray bar 1 around the nozzle longitudinal axis 2 in this way. L Schematic side view of the surrounding spray jet BS. Fig.11 As can be seen in FIG. 1 , the spray jet BS therefore moves with its jet main direction HS in a circumferential manner around the generally conical jacket-shaped surface.

[0055] In an advantageous embodiment, a corresponding spray bar, such as the spray bar 1 or the spray bars 11 and 12, comprising a guide body surrounding the nozzle 2 is arranged in the rear area of ​​the toilet bowl TS in such a way that the spray jet BS is emitted by the guide body surrounding the nozzle 2 toward the front and upward at an angle inclined to the vertical line at about 40° to about 65°, in particular between about 50° and about 55°.

[0056] Figure 2 A toilet spray device according to the invention is shown in an embodiment with two spray bars 1 equipped with guide rail nozzles: a first spray bar 11 and a second spray bar 12, which are preferably independently of each other according to Figure 1 The type of toilet bowl TS is brought to its corresponding functional position at the toilet bowl, for example by Figure 1 The spray bar 2 is moved out of the initial or rest position in a similar manner as explained above. Figure 2 In the embodiment of the invention, the functional position of the second spray bar 12 is arranged parallel to the functional position of the first spray bar 11, wherein one of the spray bars preferably remains in its initial / rest position while the other spray bar is in its functional position. Figure 2 In the operation of the toilet spray device, the spray rod 11 is preferably used to clean the female buttocks and female private area, and the spray rod 12 is preferably used to clean the male buttocks.

[0057] In an advantageous embodiment, the guide body surrounding the jet outlet opening 5 of 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 of φ shows a corresponding oval or elliptical portion of the cross section of the jet outlet opening 5 .

[0058] In an advantageous embodiment, the orbiting track 7 has, as in the example shown, an oval shape, in particular an elliptical shape, as in Fig. 9 Visible in.

[0059] In a corresponding embodiment, as in the example shown, the major semi-axis 5 of the oval cross section of the jet outlet opening 5 is G (exist Figure 7 The diameter of the jet outlet opening 5 extending in the left-right direction) and the large semi-axis 7 of the oval shape of the orbit 7 are G (exist Fig. 9 Correspondingly, the oval cross section of the jet outlet opening 5 and the oval-shaped minor axis 5 of the orbit 7 are also parallel to each other. K ,7 K parallel to each other, Figure 7 and 9 The corresponding diameter along the up-down direction.

[0060] In a corresponding embodiment of the guide body surrounding the nozzle 2, the jet main direction HS of the spray jet BS given by the guide body surrounding the nozzle 2, as in the example shown, surrounds an oval path 9, the major semi-axis 9 of which is G The major semi-axis 5 of the oval cross section inclined to the jet outlet opening 5 G and / or inclined at an angle α to the major axis 7 of the oval shape of the orbit 7 G Both properties are implemented in the example shown.

[0061] Fig.13 The spray jet BS for the guide body surrounding the nozzle 2 is shown perpendicular to the nozzle longitudinal axis 2 L The impact diagram in the plane of FIG. 5 , wherein in this embodiment the jet outlet opening 5 and the large semi-axis 5 of the orbit 7 are G ,7 G The direction of coincidence is called the x-direction and the direction perpendicular thereto is called the y-direction. The x-direction is preferably parallel to the longitudinal axis 1 of the spray bar 1 L Or a direction inclined at an acute angle to it. As can be seen from this, the impact maximum, i.e. the maximum jet intensity of the spray jet BS, is located in the oval or elliptical annular region. In other words, the jet main direction HS of the spray jet BS is located in the region with the major semi-axis 9 G and the minor semi-axis 9 perpendicular to it K The oval track 9 of the spray jet BS is encircled. The inclination angle α can be, for example, between 0° and about 60°, in particular between about 30° and about 60°, or in particular between about 40° and about 50° in the corresponding embodiment. It should be noted that the angular orientation of the oval track 9 of the impact characteristic of the spray jet BS changes with the changing distance between the spray jet BS and the guide body surrounding the nozzle 2, that is, the inclination angle α changes, for example, with the changing distance.

[0062] When desired, the major axis 9 of the oval track 9 G The jet main direction HS of the spray jet BS is parallel to the longitudinal axis of the toilet bowl TS and therefore usually also parallel to the longitudinal axis 1 of the spray rod 1 at a predeterminable theoretical distance between the impact surface and the jet outlet opening 5 of the guide body surrounding the nozzle 2 or the spray rod 1. LThe jet outlet opening 5 and / or the orbit 7 are oriented in their angular position on the spray bar 1 such that their semi-axis 5 G ,7 G The spray bar 1 is tilted with respect to the longitudinal axis 1 of the spray bar 1 by the offset angle α1 of the value determined above in accordance therewith. L Extension.

[0063] exist Fig. 20 In this context, the following is illustrated by way of example in which the jet outlet opening 5 and the semi-axial axis 5 of the orbit 7 are connected. G ,7 G The spray rod 1 is respectively offset at an angle α1 relative to the longitudinal axis 1 L The guide body surrounds the longitudinal axis 2 of the nozzle 2 L The oval path 9 is oriented in a twisted manner, wherein the offset angle α1 in this case is approximately 45° and shows that then at a predetermined theoretical distance between the impact surface of the spray jet BS and the spray bar 1 the oval path 9 is oriented with its major semi-axis 9 with respect to the jet main direction HS of the spray jet BS. G Approximately parallel to the longitudinal axis of the spray bar 1 L Similarly, in Figure 2 It can be seen that the oval outlet of the guide body surrounding the nozzle 2 is inclined with its major half axis to the longitudinal axis 1 of the spray rod. L Orientation. In general, the offset angle α1 , such as the tilt angle α, is preferably in a range between approximately 0° and approximately 60°, in particular between approximately 40° and approximately 50°.

[0064] The associated jet deflection angle for the spray jet BS (ie the angle between the respective extreme positions at the reversal point of the oval or elliptical annular area) is φ = 1. G The jet deflection is preferably in the range between about 6° and about 20°, for a jet parallel to the minor semi-axis 9 K The jet deflection is preferably in the range between approximately 3° and approximately 10°.

[0065] The jet characteristics of the spray jet BS of the guide body surrounding the nozzle 2 result from the guide function of the guide body 8 that surrounds the surrounding track 7. The supplied spray fluid rests on the guide body 8 and is thus directed to the side relative to the nozzle longitudinal axis 2. L deflected and as a spray jet BS to accordingly from the nozzle longitudinal axis 2 L The jet main direction HS deflected in the direction of escapes from the jet outlet opening 5. Fig.11 When the 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 dotted line is Fig.11When the nozzle chamber 3 is located on the left side, the jet main direction HS follows the solid line. In other words, the orbital movement of the guide body 8 on the orbital track 8 causes the jet main direction HS of the spray jet BS to move around the nozzle longitudinal axis 2 L Surrounded by.

[0066] In an advantageous embodiment, the longitudinal axis 5 of the jet outlet opening 5 is L Parallel to the longitudinal axis of the nozzle 2 L , and the guide body has a plurality of inlet openings 10 around the nozzle 2, as in the example shown. The inlet openings 10 are arranged around the nozzle longitudinal axis 2 L The nozzle chamber wall 6 is arranged in the region of the surrounding track 7 at a distance from one another on the circumferential side, as shown in FIG. Fig. 9 In this case, the inlet opening 10 opens into the nozzle chamber 3 in such a way that it is inclined with respect to the nozzle longitudinal axis 2 . L The longitudinal axis of the track 7 extends with a direction component in the circumferential direction around the track 7.

[0067] In the example shown, the inlet opening 10 is formed by the outlet of a subordinate substantially straight-running inclined channel 11, which opens out of one of the distribution chambers 12 arranged upstream of the nozzle chamber 3, such as from Figure 5 , 6 Via the inlet opening 10 , the spray fluid thus passes with a corresponding directional component in the circumferential direction of the orbital path 7 into the nozzle chamber 3 and with its fluid pressure drives the guide body 8 into its orbital movement on the orbital path 7 .

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

[0069] In an advantageous embodiment, the guide body 8, as in the example shown, is a ball which rolls and / or slides on the orbiting track 7, the ball diameter of which corresponds substantially to the maximum chamber height of the nozzle chamber 3 in the region of the orbiting track 7. In other words, in this case, the height of the nozzle chamber 3 is only so much greater than the diameter of the guide body 8 that an unhindered orbiting movement of the guide body 8 on the orbiting track 7 is achieved. By means of the only slightly higher nozzle chamber 3, the guide body 8 remains guided as far as possible through the adjacent nozzle chamber wall during its orbiting movement. In particular, the upper nozzle chamber wall 4 limits the lifting movement of the guide body 8 from the lower nozzle chamber wall 6, at which the orbiting track 7 is formed, wherein the lifting movement is caused by the spray fluid supplied via the inlet opening 10 at the lower nozzle chamber wall 6.

[0070] In an advantageous embodiment, the toilet shower device according to the invention comprises a second spray jet outlet nozzle which is designed as a guide rail nozzle 13 for a jet direction component K directed upwards in the functional position of the toilet shower device. S2 A second spray jet BS2 is emitted in a jet main direction HS2 , which is driven by fluid pressure and moves periodically in an oscillating manner in the jet plane between the two end positions BE1 , BE2 .

[0071] Such a guide rail nozzle 13 is in accordance with Figure 1 and 3 In the spray bar 1 to 18 and in Figure 2 The spray rod 11 is arranged in the first spray rod 11, more precisely in the longitudinal direction of the spray rod 1 with a closer spacing to the guide body surrounding the nozzle 2 toward the free spray rod end, such as for example from Figures 1 to 5 Visible. Figure 4 , 5 , 10, 14, 17 and 18 each show the guide rail nozzle 13 in a cross section parallel to the jet plane. Fig.14 , 17 18 shows the second spray jet BS2 in this end position BE1, BE2. As can be seen from this, the jet main direction HS2 of the second spray jet BS2 in the two end positions BE1, BE2 is in the longitudinal axis 13 of the guide rail nozzle 13. L on the opposite sides, more precisely, inclined to the longitudinal axis 13 of the guide rail nozzle L Extension.

[0072] The guide rail 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 portion 16 limiting the nozzle chamber 14, which serves as a guide rail for the second spray jet BS2. This feature of the guide rail nozzle 13 is, for example, Figure 5 , 10 , 14, 17 and 18 can be identified. Fig.15 The second spray jet BS2 which is moved back and forth in this way in the jet plane between two end positions BE1 , BE2 , as it is produced by the guide rail nozzle 13 during operation, is shown in a schematic side view. Fig.16 Similar to Fig.13 The impact diagram of that shows as follows and how the area of ​​maximum jet intensity of the spray jet BS2 is therefore a corresponding linear impact area, which extends essentially in the x direction, ie essentially parallel to the spray bar longitudinal axis 1 L The associated jet deflection angle, ie the angle between the two end positions BE1 , BE2 , is preferably in the range between approximately 12° and approximately 20°.

[0073] In an advantageous embodiment, a corresponding spray bar, such as the spray bar 1 or the spray bar 11, comprising a guide rail nozzle 13 is arranged in the rear area of ​​the toilet bowl TS in such a way that the spray jet BS2 is emitted by the guide rail nozzle 2 at an angle inclined forward and upward at a vertical line of about 40° to about 65°, in particular between about 55° and about 60°.

[0074] In a corresponding embodiment, the guide rail nozzles 13 are arranged on the same spray bar 1 as the guide body surround nozzles 2. Figure 1 The spray bar 1 and Figure 2 This is the case in the case of the first spray bar 11 of the guide rail nozzle 13. Alternatively, the guide rail nozzle 13 can be arranged at a different spray bar 1 than the guide body surrounding nozzle 2. Figure 2 This is the case in the exemplary variant of , in which the first spray bar 11 has only the guide rail nozzle 13 and no additional guide body surrounding nozzle 2. As already mentioned above, in the case of a plurality of spray bars, such as the first and second spray bars 11, 12, the functional positions of the spray bars are oriented parallel to one another, alternatively also non-parallel.

[0075] Typically, the guide body surround nozzle 2 is primarily suitable for cleaning the anus, while the guide track nozzle 13 is preferably suitable for cleaning the female private area.

[0076] In an advantageous embodiment, the nozzle chamber 3 of the guide rail nozzle 2 comprises, as in the example shown, an inlet-side mouth-shaped part region 14a, an annular chamber region 14b surrounding the mouth-shaped part region 14a at the rear, and an outlet region 14c connected to the mouth-shaped part region 14a and the annular chamber region 14b in the flow direction of the spray fluid, wherein the outlet region 14c has a central portion in the longitudinal axis 13 of the guide rail nozzle. L The two limiting jets on the opposite sides of the Fig.10 , 14 , 17 and 18 are identifiable.

[0077] In an advantageous embodiment, the jet contact walls 16a, 16b, as in the example shown, each have a convex first contact wall region 17 which has the effect of widening the channel and a concave second contact wall region 18 which is connected thereto in the direction of the associated jet outlet opening 15 and has the effect of narrowing the channel. This design of the contact wall regions 17, 18 accordingly provides a first contact wall section 19 which extends obliquely outwards, a connected second contact wall section 20 which extends obliquely inwards and a final third contact wall section 21 which extends obliquely outwards. The associated dimensioning measures are Fig.19 A possible embodiment is illustrated in FIG.

[0078] As in Fig.19In an advantageous embodiment, the radius of curvature R1 of the corresponding first contact wall region 17 (in particular the radius of curvature R1 of the upstream region 17, which is directed toward the longitudinal axis 13) is shown in FIG. L The portion that is arched forward in a drum-like manner) is in the range of 0.3 mm to 0.6 mm, in particular between 0.43 mm and 0.47 mm. In addition, in an advantageous embodiment, the radius of curvature R2 of the corresponding second contact wall region 18 (in particular the upstream portion thereof, from the longitudinal axis 13 L The angle β of the corresponding second contact wall section 18 (particularly the angle between the downstream, obliquely inwardly extending contact wall section 20) is in the range of 100° to 120°, in particular 102° to 108°. The angle β of the third contact wall section 21 extending obliquely outwardly directly in front of the longitudinal axis 13 is in the range of 1.2 mm to 1.6 mm, in particular 1.48 mm to 1.53 mm. In addition, in an advantageous embodiment, the angle β of the corresponding second contact wall section 18 (particularly the angle between the downstream, obliquely inwardly extending contact wall section 20) is in the range of 100° to 120°, in particular 102° to 108°. L The radius of curvature R3 of the drum-shaped forwardly arched section is preferably in the range of 0.3 mm to 0.9 mm, in particular 0.7 mm to 0.75 mm. The angle δ at which the jet contact walls 16a, 16b extend toward each other in front of the first contact wall region 17, which acts as a convex channel widening, is preferably in the range of 30° to 35°, in particular 31° to 33°. The angle γ enclosed by the third contact wall section 21 extending obliquely outward is preferably in the range of 90° to 110°, in particular 95° to 100°.

[0079] In a corresponding embodiment of the invention, the jet deflection angle of the guide rail nozzle 13 , ie the angle between the end positions BE1 , BE2 of the jet main direction HS2 of the spray jet BS2 , lies in the range between 12° and 20°.

[0080] Subsequently, according to Fig.17 and 18 , the working principle of the guide rail nozzle 13 is explained. Once the spray fluid is supplied to the mouth-shaped piece area 14a, it comes out of the mouth-shaped piece area and arrives mainly along the nozzle longitudinal axis 13 L The spray fluid flows in the longitudinal direction to the outlet region 14c. Depending on the pressure, a lower portion of the spray fluid flows into the annular chamber region 14b, as indicated by the flow arrow P S In the outlet region 14c, the spray fluid mainly rests against one of the two jet resting walls 16a, 16b, for example first against Fig.10 , 14 , 17 and 18, the left jet is close to the wall 16a, as shown in FIG. Fig.17 The spray fluid then moves from the left jet against the wall 16a to the right with its jet main direction HS2 inclined to the nozzle longitudinal axis 13L Or it is deflected obliquely to the longitudinal axis of the jet outlet opening 15 and escapes from the deflection track nozzle 13 or its jet outlet opening 15 in the jet main direction HS2, such as Fig.17 Presented in.

[0081] The resulting spray fluid flow in the nozzle chamber 14 of the deflected track nozzle 13 causes a negative pressure in the nozzle chamber 14 acting on the spray jet BS2 in the direction of the opposite jet contact wall 16b, thereby pulling the spray jet BS2 onto the opposite jet contact wall 16b. Fig.17 Through the subordinate pressure arrow P D Thus, the spray jet BS2 is composed of Fig.17 The direction shown in the figure is transformed to Fig.18 , in which it abuts against another jet abutment wall 16b and is guided by it with its jet main direction HS2 in Fig.14 , 17 and 18, which are inclined to the left relative to the longitudinal axis 13 of the nozzle. L deflection.

[0082] The negative pressure acting in the opposite direction then causes the spray fluid flow in the nozzle chamber 14 to pull the spray jet BS2 toward the opposite jet contact wall, in this case toward the jet contact wall 16a, see Fig.18 The pressure arrows P with opposite directions D Therefore, the spray jet BS2 is composed of Fig.18 The trend shown in the figure is reversed back to Fig.17 The direction shown in .

[0083] This reciprocating tumbling movement in the associated tumbling or jet plane continues periodically, wherein the tumbling frequency depends on the guide rail nozzle 13 , in particular on the dimensioning of its components and on the fluid pressure or flow rate at the spray fluid.

[0084] As the exemplary embodiments shown and explained above make clear, the present invention provides for use a toilet spray device which can be realized with relatively low production 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.
