Description

The present invention relates to a shower device which can be mounted on a bowl, in particular a toilet bowl.

In particular, a mobile shower device is intended, which is therefore only temporarily mounted on the bowl in order to implement a pelvic shower function for a user sitting over the bowl or on the bowl during assembly. For this purpose, the shower device has a fastening area with a fastening device. It also includes a shower arm with a shower nozzle therein, the shower arm of course being connected to the attachment means.

For the abdominal shower function, the shower device should protrude slightly downwards from this edge into the bowl opening when mounted on a bowl edge, for which purpose the shower arm, but also other parts of the shower device, can be used. On the other hand, it makes sense to design the fastening device in such a way that it can be attached to the edge of a bowl, in particular as a flat fastening device for a flat area of the edge of the bowl. The part of the shower device present in the area of installation on the edge of the bowl is referred to here as the attachment area. Between this and the shower arm, the shower device has a kink area in which, in particular, a water line of the shower device for feeding the shower attachment to the shower arm and to the shower nozzle undergoes a change in direction that is more than 20° downwards.

As far as such a shower device is already known from DE 2 410 717 A1 .

On this basis, the invention addresses the problem of specifying a favorable design for a shower device that can be mounted even temporarily on a bowl.

From the point of view of the inventors, the aim should be to design the shower facility as flat as possible, especially in the bend area, i.e. the area where the water pipe changes direction (with regard to the direction of flow of the water), because the shower facility is particularly unobtrusive and particularly favorable under a toilet seat or the like can be accommodated. Even without a toilet seat, a flat design doesn't add much bulk. The terms "attachment and buckling area" are to be understood spatially and not related to necessarily connected or separate components.

Accordingly, the invention provides that the water line in the bend area of the shower device has a dimensionally stable flow cross section on the one hand and is therefore not caused by e.g. B. the contact with a bend in the edge of the bowl can already be deformed, on the other hand this flow cross-section is flat, i.e. shorter in the vertical direction (relative to the installed position of the shower device) than perpendicular to it in the horizontal direction (and of course perpendicular to the flow direction). In this sense "flat" are z. B. a transversely elliptical flow cross-section or a transversely rectangular or transitions therebetween (rectangles with rounded corners and the like).

The flatter flow cross section allows a flat design of the shower device in this kink area per se, with a still favorably dimensioned flow cross section to avoid excessive line resistance. In addition, the dimensional stability avoids flattening, which reduces the flow cross-sectional area too much.

Preferably, the statement for the flat flow cross-section also applies to a downstream area, for example up to a transition into the shower arm, where greater overall height is then possible anyway due to the increasing distance from the edge of the bowl. The flow cross-section naturally refers to an area perpendicular to the direction of flow.

A flexible water pipe part is preferably provided upstream of the kink area. There is less of a risk of flattening and a flexible water line part makes it easier to connect the shower device to a shower water supply, for example to the basic device described in more detail below. The transition can B. happen with a part of the dimensionally stable water line part provided connection piece on which a hose is attached as a flexible water line part or is.

In this case, the connecting piece can preferably already have a flow cross section which is flat in the above sense. A corresponding cross-sectional shape is thus impressed on the flexible water pipe part at least in the area of the connecting piece, with the hose otherwise being able to have a circular cross-section for reasons of simplification (in the unloaded state). If this is flattened a little on a flat toilet bowl rim, for example, it doesn't do any harm.

The kink angle already mentioned, ie the change in direction of the water pipe in the kink area, is particularly preferably more than 25°, 30°, 35° or even 40°. A longitudinal direction of the shower arm does not necessarily have to have such a large bending angle in relation to the water pipe direction upstream of the bending area (usually the horizontal). This is preferably over 20°, 22°, 24° or even over 25°. In the exemplary embodiment, the first-mentioned angle is approximately 47° and the second is 27°.

In a preferred embodiment, the shower device discussed here is to be attached to the (toilet) bowl and connected via a water line to a supply device that accommodates further technical devices, in particular those that require more space. In particular, a water heater can be provided in this basic device, in particular a flow heater. The base unit can in turn have a water tank with a water pump or, less preferably, a connection for the connection to a water supply network, such as another hose for connection to a rooster. In this respect, a shower device that is as small and compact as possible with the elements that make sense at exactly this point is then attached in the area of the actual bowl.

This attachment can, for. B. via a downward-facing flat mounting surface, the shower device is designed as flat as possible in the rest of the mounting area, z. B. relative to a length (parallel to the flow direction of the water in the water pipe) of the shower device in the attachment area at most 20%, preferably 15% high.

Thus, the shower facility in this area z. B. be housed under a toilet seat, even without special adjustment of this seat, such as in the form of an increase over the toilet bowl.

It can be attached in various ways, for example by snapping or clamping with the production of a positive fit with the edge of the bowl, by gluing, by means of suction cups and the like. The use of at least one adhesive pad, i.e. a flat pad, has proven to be particularly favorable, which preferably adheres without residue to a smooth bowl surface, for example to the surface of sanitary ceramics, by a large number of microscopic suction devices. This solution is residue-free (in contrast to adhesives), simple and easy to clean as well as flat to implement (in contrast to clamping devices or conventional suction cups) and after a simple cleaning under e.g. B. running water can be used many times. So e.g. For example, if cleaning is due anyway, the adhesive pad can also be cleaned before the shower device is installed the next time. A commercially available example is the Fischer brand "Vacuum Pad".

A plurality of adhesive pads can leave space between them for guiding a water pipe that has to be taken into account with regard to the overall height. In the exemplary embodiment, there are two adhesive pads and the flexible water pipe part runs between them, so that the overall heights do not add up.

With regard to simple production and/or good cleaning options, it can be advantageous to connect the shower arm to the rest of the shower device in a snap-in manner and, accordingly, to be able to disassemble it in a snap-in manner. Then z. B. snapped a more or less cylindrically shaped shower arm in a corresponding receptacle and thus connected to this also with regard to the water supply, the shower arm being removed without the need to dismantle the complete shower device and z. B. can be cleaned separately. Even if the entire shower installation is to be removed for cleaning purposes, cleaning with the shower arm separated is easier and certain areas are more accessible. The embodiment also illustrates this.

In this context, the part held in place does not necessarily have to be the complete shower arm, but the base can, so to speak, already contain a piece that could be referred to as a shower arm part. This does not change anything fundamental about the above advantages. In the case of the telescopic mechanism explained in more detail below, however, this should optionally belong entirely to the part to be removed in an unlocking manner.

In the fastening area already explained and in the bend area, the shower device can have a one-piece plastic part that contains the already mentioned snap-in connection device for the shower arm. In a preferred variant, this plastic part can make up the entire shower device in addition to the shower arm, with the exception of an element carrying the fastening surface, if present, and a flexible water pipe part, insofar as this is attached to the bowl (i.e. with the exception of the base unit). The transition between the dimensionally stable water line part and the flexible water line part can also be realized on the shower arm, as in the exemplary embodiment. The structure is therefore simple and inexpensive.

The already mentioned telescopic mechanism is a preferred embodiment of the shower arm itself and has at least two telescopic elements that can be displaced telescopically in the longitudinal direction, ie also in the direction of water flow. In this way, the telescopic mechanism can remove a shower nozzle provided at its distal end from the fastening area when it is extended and the length of the shower arm can be reduced again by retracting it. Such a telescopic mechanism is essentially cylindrical, but with changing radii, and can be snap-fitted in the manner already mentioned.

In a variant that is particularly suitable for the invention, the electric motor for driving that is usual in other shower devices for toilets is dispensed with, but a driven travel movement of the telescopic mechanism is used, namely with the aid of the water pressure of the shower water. This may be a supply line pressure, possibly initially or always moderated by an intervening valve, or it may be the pressure of a water pump. The entry movement can then z. B. via a return spring counteracting the extension movement, e.g. a helical spring provided in the shower arm.

As part of the realization as a telescopic mechanism z. B. on an inner side of a first (proximal) element a guide for shower water can be provided, ie a channel-like depression or a closed channel actually formed in the wall. In addition, when the telescopic mechanism is in a retracted state, shower water can be guided past a seal between the first element and a second element of the telescopic mechanism contained therein. This shower water can then drain to the outside via further leaks, for example through a distal annular gap between the two elements. The shower arm can therefore release water when it is retracted, which can be used advantageously in various ways. In particular, in this form a gap between the first and the second Telescopic element are flushed before and / or after the shower arm is extended or has been.

Alternatively or additionally, in this form, the contents of the water pipe from a water heater, z. B. in the base unit, are already ejected to the shower nozzle before the actual shower process, so that the user does not come into contact with this already cold shower water. For example, this can be done by initially working with a lower water pressure, so that the spray arm is not yet extending, and this water pressure is only increased afterwards, ie after the cleaning and cold water drainage process.

A very similar design option relates to an intermediate space between the second element and a third element that may be contained therein. In this case, in particular, the shower nozzle can be used to access this intermediate space, which can be arranged inside the second element when the telescopic mechanism is in the retracted state. The water can then penetrate into this space via the shower nozzle and z. B. via a similar annular gap as just described (here between the second and the third element) or via an additional opening provided in this distal area.

The shower arm, in particular as a structural unit that can be assembled and disassembled in a latching manner, can have a connection for a flexible water line part on a side opposite the shower nozzle. This can in particular be the already described connecting piece with a preferably flat flow cross section. The downstream part of the water line with a dimensionally stable flow cross section is then at least in the bend area and preferably also beyond that flat in the flow cross section in this sense.

As the exemplary embodiment illustrates, this water pipe part then opens into an interior space of the telescopic mechanism of the shower arm, whose cross-sectional shape (perpendicular to the direction of movement of the telescopic mechanism) is specified by the telescopic members and their displaceability and is accordingly larger than the flow cross-section of the upstream water pipe. In this respect, the shower arm (in the sense of a cylinder or the telescopic mechanism) can have an attachment as an extension on the upstream side, which ends in the connection, in particular the connection piece. In this case, the connecting piece can already be in the fastening area, in particular between the two adhesive pads described.

The invention also relates to the use of the shower device for the combination with the base unit.

figure 1 shows a shower device according to the invention with a shower arm 1, which is shown here in an extended state, ie with telescopic elements 8 and 9 protruding from the rest of the shower device on the right. The shower arm 1 is held in a latching manner in what is otherwise a largely one-piece plastic part 2, which in figure 2 is shown without the shower arm 1 for comparison. Also shows figure 1 still a flexible water pipe part 23 on the left edge, albeit only partially. This leads over a certain length from the actual position of use of the shower facility (at the edge of a toilet bowl) to a base unit standing on the floor next to the toilet according to Figures 9-11 .

Two adhesive pads 4 are attached to an underside of the plastic part 2 in a fastening area 3 for fastening the plastic part 2 . With these, the shower facility can be switched off figure 1 be pressed flat onto an equally flat rim of a standard toilet bowl and then adheres there. When the edge of the bowl and the adhesive pads 4 are sufficiently clean, many microscopic suction devices on the underside of the adhesive pads 4 come into effect. This means that the shower device can be removed again at will and without leaving any residue, and it may need to be cleaned before it is reinstalled.

The attachment area 3 is in the left part of the figure 1 recognizable flat area, which merges in a kink area 5 into a holding device 6 which is arranged deep and forms a latching device for holding the shower arm 1. This holding device 6 has (seen in the axial direction of the shower arm 1) essentially an inverted U-shape which is open towards the bottom, compare figure 2 and 3 , Wherein it covers the shower arm 1 like a roof upwards and to the sides. Numeral 7 designates locking projections for holding the shower arm 1; in addition, one is in the figures 1 and 2 right-facing opening for the telescopic elements 8 and 9 of the shower arm 1 narrowed down slightly, as above all figure 2 indicates.

There is a gap between the two adhesive pads 4, in which the flexible water pipe part 23 runs, and at one in the Figures 3 , 5-8 easily recognizable connecting piece 10 is connected to a rear part of the shower arm 1. For this purpose, the flexible line part 3 is simply slid onto the socket 10, with this socket 10 having a highly elliptical cross-sectional shape Figures 3 and 5 , The flexible shower water line part 3 imposes. Moreover, if the overall height is a significant problem, the flexible water pipe part 3 can also be somewhat flattened between the flat structures holding the adhesive pads 4 in the fastening area 3 .

The connecting piece 10 leads via a rigid water pipe part 11 into the actual cylinder part 12 of the shower arm 1, in which the telescopic elements 8 and 9 are also housed when retracted, compare those figures 5 and 8th . The rigid water pipe part 11 runs at an angle to the horizontal or the direction of the connecting piece 10, the angle according to the figures 7 and 8th is between very approximately 45° and 60° (depending on whether the upper or lower limit is considered). The rigid water line part 11 widens and thus guides the shower water into the cylinder part 12 already mentioned, the corresponding rear boundary of this cylinder part 12 being designed obliquely and thus continuing the lower wall of the rigid water line part 11 in a certain sense, compare figure 7 and 8th .

The rigid water pipe part 11 also has a flat-elliptical flow cross-section downstream of the connecting piece 10, whereby it is evident from the Figures 5-7 widens in the transition into the cylinder section 12. In any case, upstream of the bend region 5, in the bend region 5 and also another A little further downstream there is a flat flow cross-section with an approximately elliptical shape.

This means that shower water can be fed to the shower arm 1 via the flexible water pipe part 3, which in turn is held in place by the plastic part 2 via an adhesive connection to the toilet bowl, but can be released from this plastic part 2 in a latching manner. Accordingly, the shower arm 1 can be removed without complete dismantling of the shower device and z. B. be cleaned. Furthermore, the separation into the two parts 1 and 2 which are connected in a snap-in manner has advantages in terms of production technology.

Moreover, the holding device 2 actually holding the shower arm 1 bends downwards at a clear angle relative to the fastening area 3, compare figure 2 , And is thus already the shower arm 1 before its axial orientation obliquely downwards. In addition, the holding device 2 largely protects the shower arm 1 from dirt in its retracted state, compare figure 4 .

As already mentioned, the shower arm 1 has a telescopic mechanism with two movable telescopic elements 8 and 9, the cylinder part 12 forming the first telescopic element, which correspondingly accommodates the second telescopic element 8 (which accommodates the third telescopic element 9). the figures 6 and 7 compared to the figures 5 and 8th show the extended and retracted state, where in the figures 6 and 7 shows a helical spring 24 tensioned between the rear inclined wall of the cylinder part 12 on the one hand and a holding arm 13 in the third telescopic element 9 on the other hand. This counteracts the water pressure supplied via the water pipe, so that the retracting and extending of the shower arm can be controlled via the water pressure.

The second and third telescopic elements 8 and 9 have radial outward projections at their respective proximal ends, which are denoted by the reference number 14 and 15 are designated and each carry an O-ring for sealing. As the figures 6 and 7 show, this sealing occurs in the extended state by abutting against an inwardly pointing radial collar at the respective distal end of the first and second telescopic element 12 and 8, respectively. In the retracted state, however, this seal does not exist. Rather then bridges an in figure 7 and figure 8 recognizable channel depression 16, which is actually distributed three times over the circumference, the proximal radial projection 14 and guides water past this into the intermediate space 17 ( figure 8 ) between the cylinder part 12, i.e. the first telescopic element 12, and the second telescopic element 8.

In addition, one leads to the Figures 6-8 clearly visible shower nozzle 18 water into an intermediate space 19 between the second telescopic element 8 and the third telescopic element 9. The water from the first-mentioned intermediate space 17 can flow through a distal annular gap within the radially inward-pointing distal collar of the cylinder part 12, but above all through an in figure 8 with 20 designated small opening in the lower part of the annular gap exit. In the retracted state, this opening 20 is covered by a nose 21 pointing downwards at the distal end of the third telescopic element 9 . The water from the intermediate space 19 similarly exits through the distal annular gap between the second telescopic element 8 and the third telescopic element 9 .

So if there is a certain water pressure which is not yet sufficient for the extension of the shower arm 1, the gaps 17 and 19 and thus the corresponding surfaces of the telescopic elements are flushed. This also applies while driving out. If the water pressure is not switched off abruptly at the end of a shower, the same applies to running in and any time afterwards.

the Figures 6 to 8 Incidentally, show below and upstream of the shower nozzle 18 a turbulence chamber 22, to that of the prior art

EP 2 629 546 and which is connected to an internal cavity in the third telescopic member 9 (and otherwise the internal cavities in the second and first telescopic members) proximal thereto by a short axially extending length of conduit.

The nose 21 already described at the distal end of the third telescopic element 9 also serves as a stop when retracting, because it comes into contact with the distal end of the second telescopic element 8 below, specifically in a niche provided specifically for this purpose, compare figure 1 . In addition, the nose 21 is long enough so that z. B. in the event of jamming or without water pressure, the shower arm 1 can also be extended manually. To do this, the nose 21 is simply pulled with a finger.

For the supply of in the Figures 1-8 illustrated and explained above shower device is a base unit 30 according to Figures 9-11 responsible, which together form a set as a mobile solution for upgrading an ordinary toilet to a shower toilet.

figure 9 shows a water tank 31 with an essentially cuboid shape, which is placed on a base part 32 and covered by a cover 33 at the top. The water tank 31 can consist of transparent or translucent material and can display the water level. If necessary, it is simply lifted upwards, for which purpose two recessed grips, one of them in figure 9 visible and numbered 34. After the lid 33 has been lifted off, the water tank 31 can then be filled, placed back on the base part 32 and closed again with the lid 33 . Without the lid, the water tank is about 16.5 cm high and can therefore easily be placed under a tap, e.g. B. to keep in a sink.

The base part 32 also essentially has the shape of a cuboid. It has no external switches or other controls other than what is related to figure 10 is explained. If the in figure 9 visible housing cover is removed, the result is a view like in figure 11 , which is not explained in detail.

In any case, there is a central elastomeric element 35 for which the housing cover has a central recess and into which a valve of the water tank 31 engages. A central pin 36 can be seen within the elastomer part 35, with which the valve of the water tank 31 is automatically opened (and closed again when lifted off). In addition, the elastomer part 35 is designed in one piece with a hose 37 that leads to the water pump 38 . The water pump 38 is mounted in a vibration-insulated manner to reduce noise and is connected to a continuous-flow heater 39 in a manner that is not shown in detail.

figure 11 shows an approximately vertically upward-pointing lever 40 in front of the continuous-flow heater, which has a second lever arm, not shown here, close to the ground and running approximately at right angles thereto. The second lever arm can be connected via an in figure 10 pushbutton 41 shown above can be pushed upwards and is articulated with its end opposite to the transition (to the second arm). Accordingly, depressing button 41 results in inward movement of the in figure 11 shown vertical arm of the lever 40, which actuates an electric button concealed behind it and the reset function of an overheating protection of the instantaneous water heater 39 is triggered.

Incidentally, the base portion 32 includes an electronic controller 42 and some other parts that are not particularly relevant to the understanding of the present invention. The controller 42 has an interface according to the "Low Energy Bluetooth" standard and can, for. B. be addressed via an app on a mobile phone. The user can thus operate the shower function and also program the controller 42 without touching the base unit 30 . Only the reset function with the mechanical button 41 is an exception here.

figure 10 12 shows a bottom view of the base part 32. FIG figure 9 . In addition to the button 41 already mentioned, there is a connecting piece 43 for a not shown here and in figure 1 visible with its other end visible flexible water pipe part 23, which is quite a length of z. B. can have more than a meter to a flexible arrangement of the base unit figure 9 next to the toilet bowl allow. The water line leading to the socket 43 is in figure 11 numbered with 44 and leads from the water heater 39 ago.

Furthermore, one sees in figure 10 an electrical connection cable, the continuing portion and plug of which are omitted, and which bears the symbol 45. This cable is wrapped around a flat spigot 46 which can be found in figure 10 with its lowest section, which is somewhat enlarged compared to the "remaining part" behind it. Accordingly, the remainder of the cable 45 lies behind the visible surface but is wrapped around a remainder of the spigot 46 approximately corresponding to the central oval 47 . At the same time, the visible part of the pin 46 forms a support and ensures that the in figure 9 visible lower edge of the base part 32 is about 3 mm above the ground.
