Description

[0001]Toilet seat ring Description The invention relates to a toilet seat ring with at least one under-shower having a nozzle for dispensing water, wherein the toilet seat ring is designed to be pivotable. Toilets with under-shower devices are also known as "shower toilets". Shower toilets known on the market have an integrated shower function for the anal and / or genital area of ​​the user. For this purpose, the under-shower device has a nozzle through which the water is discharged in the direction of the area to be cleaned. The nozzle is generally extendable, either electromechanically or under water pressure. In the latter case, the water pressure is used to feed the nozzle. The under-shower device is preferably controlled by a valve, which opens and closes the water supply. The actuation can be manual, for example, by turning the valve, or electromechanically, whereby the electromechanical control triggers a pulse that opens or closes theClosing of the valve. In addition, the flow rate can often be regulated. Shower toilets with an integral shower facility are highly developed toilets that, depending on the equipment, have additional functions, such as a drying function, heating function of the toilet seat ring, and the like. Such shower toilets have generally proven themselves. However, their complexity makes them very expensive. As an alternative to shower toilets with an integral shower facility, shower facilities are now being offered as retrofit parts for conventional toilets. DE 202006 013 209 U1 discloses a toilet seat attachment that can be retrofitted as an additional module to a conventional toilet. The toilet seat attachment has a shower head and can be attached to a toilet ceramic in such a way that a conventional toilet seat is mounted in front of the toilet seat attachment. EP 2938 790 B1 discloses a toilet seat attachment that can also be retrofitted as an additional module to a conventional toilet. The toilet seat attachment hasa shower head and horizontal pivot axes to which a toilet seat can be attached. The known toilet seats provide a cost-effective and at the same time user-friendly option for retrofitting a shower facility to an existing toilet. In particular, all necessary components can be accommodated in the known toilet seats. In addition to the shower head and the valve, this also includes a possible drinking water safety device. The known toilet seats require a considerable amount of space, as they are placed behind the toilet seats. This is where the invention comes in. The invention is based on the object of further developing retrofittable toilet seats such that the overall arrangement consisting of the toilet seat and shower head takes up less space. This object is achieved by a toilet seat ring with the features of claim 1. According to the invention, the toilet seat ring has a receptacle, which is preferably designed as a cavity. In theA water line connecting the valve and the under-shower is accommodated in the receptacle. The receptacle is formed in the pivoting section of the toilet seat ring. It is advantageously an integral component of the pivoting toilet seat ring. The water line can be, for example, a hose, in particular a silicone hose, whereby the water line can also consist of several sections. Its task is to direct the water from the valve to the under-shower when the under-shower is activated. A drinking water safety device can be interposed, as will be explained in more detail later. If several under-showers, in particular two under-showers, are used, each under-shower is assigned a water line. The two water lines can preferably be fed by one or two valves. The invention proposes a completely new way of accommodating the components required for the operation of the under-shower.which are accommodated in the WC seat ring according to the invention. According to the invention, this is at least the water pipe. The accommodation of further components is preferably possible. The receptacle (and thus also the components located in the receptacle) is folded up together with the WC seat ring when the WC seat ring is folded up. Due to the inventive accommodation of the components, a WC attachment arranged behind the WC seat ring is not required, as in the prior art, which leads to a considerable space saving of the overall arrangement. This applies in particular when the under-shower is also arranged on the WC seat ring, which is considered advantageous. A further significant advantage lies in cost-effective production, since compared to the known designs in which the components are arranged behind the pivoting WC seat ring (in particular its pivot axis), theThe functional unit can be omitted. The toilet seat ring can be designed as an independent ring without a lid within the scope of the invention. It can also be part of a toilet seat. This then additionally has a toilet seat lid. Furthermore, the toilet seat ring can be designed to be open in the front area. It is then not completely circumferential. The valve is preferably arranged on the toilet seat ring, particularly preferably at least partially accommodated in the receptacle. Preferably, the valve has a valve body and an actuating device by means of which the valve body is actuated. The actuating device is designed, for example, as a rotary knob. It can be arranged outside the receptacle so that the valve can be easily operated by a user. Preferably, the receptacle is delimited by a base plate. This offers the possibility of making the receptacle accessible, for example, for inspection or repair.facilitates assembly. Against this background, it is proposed that the base plate is advantageously detachably connected to the toilet seat ring. For example, the base plate can be screwed to the toilet seat ring. In terms of space, it is particularly advantageous if the base plate is arranged on the underside of the toilet seat ring. Preferably, the base plate together with the toilet seat ring forms the cavity. In a further development of the invention, it is proposed that the valve be arranged, in particular fastened, to the base plate. Additionally or alternatively, the under-shower can be arranged on the base plate. This enables a simple connection of the base plate to the toilet seat ring. In particular, arranging the components on the base plate allows for advantageous pre-assembly, so that during final assembly, only the base plate needs to be fastened to the toilet seat ring. As mentioned above, the base plate advantageously limits the receptacle. ItThis takes on two tasks, namely, on the one hand, a support function for the respective components and, on the other hand, an at least one-sided enclosure of the receptacle. An advantageous embodiment is characterized in that (in the horizontal position of use of the toilet seat ring) the at least one under-shower extends downwards. The water pipe, preferably the valve and / or, if applicable, a drinking water safety device is arranged on the upper side of the base plate, as will be explained in more detail below. Such a construction is particularly compact. Particularly preferably, the at least one under-shower can be pulled out downwards from the base plate. This has advantages in terms of space, particularly when the under-shower is at least partially accommodated in the receptacle. The aim of the under-shower is, on the one hand, to be compact in order to keep the overall construction compact. On the other hand, the under-shower must be in the extended operating position inbe able to easily reach the area to be washed. The under-shower must not come into contact with the human body. Against this background, it is proposed that the under-shower, in an installed position, preferably extends diagonally downwards and forwards. This brings the nozzle closer to the area to be washed. On the other hand, the diagonal path of movement avoids contact with the human body. When extending, the nozzle preferably moves on a downwardly curved path. For this purpose, the extendable cylinders of the under-shower themselves are curved. In an advantageous embodiment, the under-shower has a sleeve and a hollow cylindrical piston movably guided in the sleeve. The sleeve advantageously extends downwards from the base plate. The hollow cylindrical piston is retracted in its rest position. During operation, for example when exposed to water, it extends out of theSleeve. After operation, it is pulled into the sleeve due to spring force. When two under-showers are provided, two sleeves are advantageous. The nozzle is expediently arranged in the end region of the hollow cylinder piston. Preferably, the sleeve is formed integrally with the base plate. It can therefore be manufactured together with the base plate, which is advantageous from a manufacturing perspective. Furthermore, the integral manufacture ensures a high level of tightness. An advantageous embodiment of the toilet seat ring according to the invention is characterized in that at least one drinking water safety device is arranged in the receptacle, preferably on the base plate. The drinking water safety device is arranged fluidically between the valve and the under-shower and is preferably part of the water line. Relevant components can therefore be stored in the receptacle, which is advantageous in terms of space. The arrangement of these components on the base plate has assembly-relatedAdvantages. If the base plate is detachably connected to the toilet seat ring, a further advantage is that the components can be connected to the toilet seat ring together with the base plate and detached from the toilet seat ring together with the base plate. All components are mounted at a designated location on the base plate. Therefore, for correct alignment, only the base plate needs to be correctly mounted to the toilet seat ring to ensure that all components are in their designated location. This is particularly true if the under-shower is also arranged on the base plate, which is considered advantageous. In one embodiment, the drinking water protection is arranged within a cover, which is preferably sealingly mounted on the base plate. This design has the advantage that the toilet seat ring can be opened without any leakage. For this purpose, theThe lid does not have to be mounted on the base plate in a completely sealed manner. It is advantageous if the lid is at least partially sealed against the base plate. The lid is advantageously arranged in the receptacle. The drinking water safety device is advantageously attached to the base plate or to the lid. Additionally or alternatively, the under-shower can advantageously be attached to the lid. It is expedient for the water pipe to pass through the lid. For this purpose, the lid advantageously has a through-opening. It is considered particularly advantageous if the drinking water safety device extends through the lid at one end. This enables a stable seal against the lid. The pipe can be plugged onto the end and additionally secured if necessary. This ensures a good seal of the pipe system. To supply the at least one under-shower with water, the toilet seat ring advantageously hasa water connection. The water flow to the nozzle is regulated via the valve. It is either an on-off valve, which has two operating states and can be switched on or off. Alternatively, the valve can be used to regulate the water quantity. Advantageously, the valve has a valve body that fluidically connects the water connection to the nozzle, and an actuating device that serves to (preferably manually) actuate the valve body. The actuating device, which can be designed as a button, in particular a rotary knob, is preferably arranged outside the receptacle. According to the invention, the toilet seat ring has at least one under-shower. It can also have two under-showers. If one under-shower is to be operated, the actuating device is turned in one direction (for example, to the right). If the other under-shower is to be operated, the actuating device is turned in theother direction. Depending on the direction of rotation, one or the other under-shower can be controlled. Therefore, only one valve is required to supply both under-showers. The water connection is used for connection to a stationary domestic water supply. For example, a connecting hose with a union nut can be considered here. When installed, the union nut is in threaded engagement with the water connection. Nevertheless, the water hose is advantageously rotatable compared to the toilet seat ring. This has the particular advantage that when the toilet seat ring is opened, no torsional stress is exerted on the connecting hose, which could lead to a loosening of the rotating connection between the connecting hose and the water connection. Rather, the rotating connection allows the connecting hose to remain free of torsional stress. Preferably, at least oneDrinking water protection is arranged. The drinking water protection can be arranged directly or indirectly – for example, via the lid – on the base plate. Such drinking water protection devices are known from the state of the art. Regulations on this can be found, for example, in the standard EN 1717. Preferably, an injector is used, in which a water jet is sprayed over a free section and collected beyond the free section. Such a drinking water protection device is known, for example, from DE 20 2012 002 585 U1. If two under-showers are used, each under-shower is assigned a drinking water protection device. With regard to handling and accessibility and thus also ergonomics, it is considered advantageous if the valve is arranged on the side of the toilet seat ring. The water connection can also be attached to the side of the toilet seat ring. In a preferred embodiment of the invention, theThe edge protrudes from the base plate. The edge serves to channel leaks that may originate from the drinking water supply. Preferably, the edge is formed integrally with the base plate. The base plate can then be manufactured together with the edge as an injection-molded part. A preferred embodiment of the invention is characterized in that the base plate has a recess for leaks. The leaks are advantageously channeled by the edge in the direction of the recess. The recess then serves to discharge the leaks into a toilet ceramic. Advantageously, the under-shower extends through the recess. The recess therefore performs two functions, namely, the outlet of leaks and, secondly, the passage of the under-shower. The under-shower can extend through the recess in an operating position in which the nozzle is supplied with water. It is also possible for the under-shower to also be in a rest position in which the nozzleis not supplied with water, extends through the recess. The base plate preferably has a screen that extends from the base plate. The screen serves, on the one hand, to shield and, if necessary, also to divert leakage. On the other hand, the screen also shields the at least one under-shower and thereby protects it. It is considered advantageous if the recess is arranged between the screen and the under-shower when viewed from the side. Thus, when the toilet seat ring is installed, the leak is discharged in front of the under-shower when viewed from the front. The screen is preferably inclined diagonally forward and downward. This diverts the leak particularly advantageously while requiring little space. This applies in particular when the screen extends adjacent to the recess, in particular behind the recess, from the base plate. In the use position of the toilet seat ring, the screen preferably extends below the recess and / or the under-shower. In this contextIt should be noted that location references such as rear, front, side, etc. refer to a toilet seat ring in the horizontal use position. The front is therefore the end of the toilet seat ring that faces a user standing in front of the toilet seat ring. Advantageously, the toilet seat ring has a pivot axis around which the toilet seat ring can pivot, and an opening for a human buttocks, wherein the receptacle is arranged between the pivot axis and the opening in a plan view of the toilet seat ring. Such a construction is very compact. The toilet seat ring forms a seating plane on which the human buttocks rest when using the toilet. Preferably, the receptacle (in the use position) extends beyond the seating plane. If a toilet seat lid is used, the lid is higher in the rear area than in the front area. It advantageously forms a raised area in the area of ​​the receptacle. In a further development of the invention,It is proposed that the toilet seat ring be designed as a component of a toilet seat which also has a toilet seat lid. The toilet seat ring and the toilet seat lid are preferably pivotable about the same pivot axis. Particularly preferably, the toilet seat lid engages over the receptacle when the toilet seat is mounted. In this case, it can completely cover the toilet seat ring. The invention is described in more detail below using a preferred exemplary embodiment in conjunction with the attached drawing. The drawing shows: Figure 1 is a schematic illustration of a rear perspective view of a first exemplary embodiment of a toilet seat according to the invention; Figure 2 is a schematic illustration of a perspective view of the toilet seat according to Figure 1, with the toilet seat lid opened; Figure 3 is a schematic illustration of a perspective, partially sectioned view of the toilet seat according to Figure 1 from below; Figure 4 is a schematic illustration of aBase plate of the toilet seat according to Figure 1; Figure 5 is a schematic representation of a perspective view of the base plate according to Figure 4 with the cover removed; Figure 6 is a schematic representation of a sectional view of the under-shower in the rest position; Figure 7 is a schematic representation of a sectional view of the under-shower in the extended state (operating position); Figure 8 is a schematic representation of a rear perspective view of a second embodiment of a toilet seat according to the invention; Figure 9 is a schematic representation of a perspective, partially sectioned view of the toilet seat according to Figure 8 from below; Figure 10 is a schematic representation of a base plate of the toilet seat according to Figure 8; Figure 11 is a schematic representation of a construction unit consisting of an under-shower, two water protection devices and a cover as well as a connected valve; Figure 12 is a schematic representation of a first perspective view of the base plate according toFigure 10 with the lid removed; Figure 13 is a schematic representation of a second perspective view of the base plate according to Figure 10 with the lid removed; and Figure 14 is a schematic representation of a partial sectional view of a connecting hose. Figure 1 shows a toilet seat 1 viewed diagonally from behind, wherein the toilet seat 1 has a toilet seat ring 2 and a toilet seat lid 3. The toilet seat ring 2 and the toilet seat lid 3 are pivotally mounted about a common pivot axis 4, as indicated by dashed lines in Figure 1. As a result, both the toilet seat ring 2 and the toilet seat lid 3 can be folded up, as is shown for the toilet seat lid 3, for example, in Figure 2. Reference numeral 5 designates a water connection, and reference numeral 6 designates an actuating device for a valve 7 (see Figure 4). The water connection 5 is used to connect the WC seat ring 2 to the building's water supply. Via the actuating device 6, theIn this case, it is designed as a rotary knob, and the water quantity is controlled to supply a shower head, as will be explained in more detail below. Reference is made to Figure 2, which shows the toilet seat 1 with an open toilet seat lid 3. From this view, it is clear that the toilet seat ring 2 has an opening 8 for a human buttocks. The toilet seat ring 2 further has at least one shower head 9, which will be explained in more detail in connection with Figures 6 and 7. The illustrated embodiment has two shower heads 9, one for the female intimate area and the other for the anal area. Both shower heads 9 are protected by a screen 10. The screen 10 protects the shower heads both mechanically and against contamination and also ensures that leakage does not splash uncontrollably into the toilet ceramic. Figure 3 shows the toilet seat 1 in a view from below. From this viewIt becomes clear that the screen 10 extends downwards from the toilet seat ring 2. The screen 10 is arranged on a base plate 11 and is preferably formed integrally with the base plate 11. The base plate 11 is detachably connected to the toilet seat ring 2, in this case via screws 12. Preferably, the base plate 11 is arranged on the underside of the toilet seat ring 2. Otherwise, the basic functions of the toilet seat, such as its attachment to a toilet ceramic, are known. According to the invention, the toilet seat ring 2 has a receptacle 13. To better illustrate the receptacle 13, the base plate 11 is shown partially cut away in Figure 3. The receptacle 13 is advantageously designed as a cavity and is preferably delimited by the base plate 11. Reference is made to Figure 4, which shows the base plate 11 on its own. The valve is identified by reference number 7. The valve 7 has the already mentioned actuating device 6 as well asa valve body 14. Depending on the direction in which the actuating device 6 is turned, the valve controls either a first hose 15 or a second hose 16. Both hoses 15, 16 lead to a nozzle 29 each. The valve 7 is supplied via the water connection 5. The two hoses 15, 16 are water lines. The water line can also be designed as a pipe, i.e. rigid, although a hose has the advantage of greater flexibility. In the present case, the water connection 5 and the valve body 14 are designed as one piece. They can also be designed separately. Preferably, both the water connection 5 and the valve 7 are mounted on the base plate 11. The reference numeral 17 designates a cover which is detachably connected to the base plate 11. As can be seen from Figure 5, two drinking water safety devices 18, 19 are arranged within the cover 17, in which, during operation, a water jet is discharged via a freesection 20. A backflow of water towards the valve 7 is therefore not possible. Such drinking water safety devices are known in principle. The water safety devices 18, 19 can be attached to the cover 17. The base plate 11 has an edge 21 which provides a barrier to leakage from the two drinking water safety devices 18, 19. When assembled, the cover 17 seals against the base plate 11. For this purpose, a circumferential seal 22 is provided. When the toilet seat ring 2 is opened, the cover 17 ensures that the leakage cannot escape. The base plate 11 has a recess 25 through which the leakage can flow away. The recess 25 is preferably arranged between the at least one under-shower 9 and the screen 10. The water protection devices 18, 19 are connected via hoses 23, 24 to an attachment 26, which serves to feed the two sub-showers 9, as can be seen from Figures 6 and 7, to whichreference is made below. The two hoses 23, 24 form the water line. The water line can therefore also be designed in several parts. The two under-showers 9 each have a sleeve 27, which is preferably formed integrally with the base plate 11. A hollow cylindrical piston 28 is slidably guided in the sleeve 27. Figure 6 shows the rest position of the front under-shower 9. If the under-shower 9 is subjected to water, the hollow cylindrical piston 28 moves out of the sleeve 27 against a spring force, as shown in Figure 7. The water can then emerge from a nozzle 29. When the valve 7 is closed, the hollow cylindrical piston 28 moves back to its starting position according to Figure 6 due to a spring force (e.g. a spiral spring). Reference is made again to Figure 1. This makes it clear that the toilet seat lid 3 engages over the receptacle 13 in the closed state. For this purpose, the toilet seat lid 3 forms in the area ofReceptacle 13 advantageously has a raised portion 30. If locational information such as front, rear, top, bottom, side, or the like is used in the description, this information is to be understood from the perspective of an observer standing in front of an installed toilet seat ring. In this case, the pivot axis 4 is located, for example, at the rear. The same applies, for example, to the receptacle 13, which is preferably arranged behind the opening 8, but in front of the pivot axis 4. The toilet seat lid 3 is located above the toilet seat ring 2 and advantageously overlaps the receptacle 13. In this respect, the invention also proposes a toilet seat with a toilet seat ring and a toilet seat lid, which have a common pivot axis 4. Figures 8 to 13 show a second embodiment of a toilet seat according to the invention. For reasons of clarity, the same reference numerals are used to describe it as in the first embodiment, even if the specific components are structurally different.slightly different. Figure 8 shows a perspective view of the second embodiment. The second embodiment differs from the first embodiment in that the toilet seat ring 2 rises gently towards the rear. This allows the toilet seat lid 3 to be flat on its upper side and not to form a raised area 30 as in the first embodiment (see Figure 1). A further difference lies in the under-showers 9. They are curved downwards, as is considered advantageous. One under-shower 9 is shorter than the other under-shower 9. This advantageously leads to different washing areas. Figure 9 shows the second embodiment in perspective from below. This clearly shows that the base plate 11 is pulled slightly further back than in the first embodiment. In addition, the base plate 11 is clipped into the toilet seat ring 2. Furthermore, it can be seen that the under-showers 9 are largely in theare received in the receptacle 13. Only their ends engage in the rest position through a recess 34 of the base plate 11. This recess 34 does not extend in a slot-like manner as in the first embodiment (see Figure 5), but allows the at least one under-shower 9 to reach through, which is considered advantageous in itself. Figure 10 shows the base plate with the cover mounted thereon. Except for the missing screen 10 (see Figure 4), this view largely corresponds to the view of the first embodiment according to Figure 4, so that reference is made to the relevant description. Figure 11 shows a perspective view of the cover 17 of the second embodiment from below. The under-showers 9 are mounted in the cover 17, whereby in the present case the two under-showers 9 are combined as a structural unit. Such a structural unit is known from the prior art. Also mounted in the cover 17 are the twoDrinking water safety devices 18, 19. The cover 17 has two through-openings 35 through which one end of the respective drinking water safety device 18, 19 extends. The respective hose 15, 16 is plugged onto the end and secured by means of a retaining ring 36. For further details, reference is made to the corresponding description of the first exemplary embodiment. Figure 12 shows a plan view of the base plate 11 with the components of the valve 7, the water connection 5, the drinking water safety devices 18, 19 and the two under-showers 9 as well as the associated hoses 15, 16, 23 and 24. For reasons of clarity, the cover 17 has been omitted. Even though the drinking water safety devices 18, 19 and the under-showers 9 are shown, they are mounted in the cover as described above. For further details, reference is made to the first exemplary embodiment. Figure 13 shows a further perspective view of the base plate 11, from which it becomes clearthat the base plate 11 has hooks 37 with which the base plate can be clipped into the toilet seat ring 2. Furthermore, the recess 34, through which the two under-showers 9 engage, is clearly visible. The recess 34 is advantageously located within the rim 21. Independently of this, the under-showers are advantageously protected by a screen 38. The screen 38 directs the leakage into a toilet bowl (not shown) and is advantageously inclined forwards and downwards for this purpose. Preferably, it engages underneath the under-showers 9. For further details of the second embodiment, reference is made to the description of the first embodiment. Figure 14 shows a connecting hose 31 for connection to the water connection 5. The connecting hose 31 has a union nut 32, which is rotatable relative to the connecting hose 31, even when the union nut 32 is firmly threaded into the water connection 5. For this purpose, the union nut 32Sealed against the connecting hose 31 by at least one O-ring, in this case by two O-rings 33. For clarity, if reference is made to a single shower head within the scope of this description, this also includes multiple shower heads, and vice versa. The invention relates to a toilet seat ring with at least one shower head, so that all described features also relate to at least one shower head.
