Description

[0001] The invention relates to a toilet with a bidet function.

[0002] Toilets with a bidet function are known in various forms from the prior art. EP 2938790 B1 discloses a toilet attachment that is mounted on a toilet bowl and features a bidet function with a nozzle. Water is directed from the nozzle for cleaning the anal or genital area. The known toilet attachment includes a drinking water safety device that prevents potentially contaminated water from flowing back. The drinking water safety device is located between a valve and the bidet function. Within the drinking water safety device, water is sprayed over a gap. If potentially contaminated water flows from the bidet function towards the valve, this water cannot overcome the drinking water safety device due to the gap.

[0003] A toilet seat attachment is also known from DE 20 2006 013 209 U1.

[0004] All common toilet seat attachments feature a swivel axis for a toilet seat that is directly attached to the attachment. This allows the toilet seat to be retrofitted if a toilet seat with a bidet function is desired.

[0005] Drinking water protection systems are generally known. They are regulated in the standard DIN EN 1717 for areas at risk of drinking water contamination. Within the scope of the present invention, a drinking water protection system of type AD (free outlet with injector) of EN 1717 is used in particular, as also known from DE 20 2012 002 585 U1. Here, a jet of water is preferably sprayed horizontally over a free space. The invention is preferably directed to such a drinking water protection system, but is not limited to it.

[0006] In addition to retrofittable bidet attachments in the form of toilet seats, toilets with a bidet function that are factory-installed are also known in practice. For example, a toilet with a bidet function is known in which the nozzle is located directly inside the toilet bowl. The nozzle is, for example, located in a rim of the toilet bowl, which flushes the interior with water as needed. This type of toilet is also referred to as a Turkish toilet with a bidet function. The invention is preferably directed to such a toilet, but is not limited to it.

[0007] Based on the known state of the art, the invention is based on the objective of equipping a toilet with bidet function with a drinking water protection system, wherein the arrangement of the drinking water protection system should be accessible on the one hand and compact on the other.

[0008] The problem is solved by a toilet having the features of claim 1.

[0009] The toilet according to the invention comprises a toilet bowl with a rear upper surface and an interior. Preferably, the toilet bowl is made of a ceramic material. A nozzle is arranged in the interior of the toilet bowl. The nozzle is preferably arranged in or on a flushing rim of the toilet bowl.

[0010] The toilet also has a housing with a base. The base can be formed by a base plate or the underside of the housing. A drinking water safety device is arranged within the housing, connected to an inlet and an outlet. The inlet and outlet can, for example, be designed as hose-like conduits. The inlet and / or outlet can be partially formed by the housing, particularly the base, as will be explained in more detail below as being advantageous. In this case, the housing serves as the water conduit. Generally, the terms inlet and outlet refer to any type of conduit capable of carrying water.

[0011] According to the invention, the inlet channel passes through a first opening formed in the base, and the outlet channel passes through a second opening formed in the base. The inlet channel and the outlet channel thus advantageously extend downwards through the base, preferably through the base plate or through the underside of the housing. This creates a compact design.

[0012] The drain channel is connected to the nozzle. It therefore preferably forms the water inlet to the nozzle.

[0013] A first recess is formed in the upper surface of the toilet bowl, through which the drain channel passes. A second recess is formed in the upper surface of the toilet bowl, through which the inlet channel passes. According to the invention, the first opening is aligned with the first recess, and the second opening is aligned with the second recess. This means that the cross-sections of the first and second openings overlap at least partially with the first and second recesses, so that the drain channel and the inlet channel can preferably be routed vertically downwards directly through the upper surface of the toilet bowl. Preferably, both the inlet channel and the drain channel are concealed by the housing, which creates not only an attractive design but also a compact construction.

[0014] It is known that leakage can occur in drinking water safety devices. Therefore, a leakage channel is provided from the housing to drain any leakage, extending into or across the interior of the toilet bowl. Preferably, the leakage channel extends forward along the top of the toilet bowl. Advantageously, an outlet is provided at its front end through which the leakage can escape and flow into the toilet bowl.

[0015] An advantageous embodiment is characterized in that two fastening devices project from the base of the housing, each engaging in a receptacle formed in the top of the toilet bowl. Preferably, these receptacles are provided in addition to the two recesses. They can be designed as openings extending through the top of the toilet bowl. The fastening devices expediently engage in the receptacles with preload. This secures the housing firmly.

[0016] The mounting devices are advantageously inserted into the receptacles from above for attachment to the toilet bowl.

[0017] Preferably, the fastening devices are designed as fastening pins and preferably each have at least one plastic or rubber bead that is held under preload in the respective receptacle. Fastening pins also include toggle bolts known from the prior art, which can be inserted into the receptacles. The toggle bolts expand advantageously after being inserted through the respective receptacle. The fastening pins engage in the receptacles and can, for example, be made of metal. The at least one plastic or rubber bead secures the fastening pin in the respective receptacle. The thickness of the bead can be dimensioned such that it has a slightly larger diameter than the receptacle. Advantageously, the preload is selected such that the fastening pins can also be withdrawn from the receptacle.

[0018] As mentioned above, a compact design is desired. Against this background, it is proposed that the first and second recesses be arranged between the two mountings. In particular, it can be provided that the two recesses and the two mountings are arranged in a line. This allows for the creation of a slim, elongated housing that fits well behind a toilet seat. In this respect, it is considered advantageous if the two mountings are arranged behind two openings formed in the toilet bowl for attaching a toilet seat. Such openings and the method of attaching the toilet seat to these openings are known.

[0019] Preferably, the inlet and outlet channels pass through the top of the toilet bowl between the two mounting points. This allows for a space-optimized design.

[0020] According to the invention, the inlet channel passes through a first opening in the base and the outlet channel through a second opening in the base. The base thus forms openings which, as already indicated above, are preferably concealed by the housing in the assembled state. The inlet channel and / or the outlet channel can, for example, be designed as a hose that passes through the respective opening and is connected to the drinking water safety device. An advantageous embodiment is characterized in that the base, in particular the base plate or the underside of the housing, has a connection for the inlet channel, which is preferably designed as a threaded connection. It can, for example, also be designed as a push-fit connection. The connection expediently extends downwards from the base and advantageously has an external thread onto which a nut of a connecting hose can be screwed.The connection, especially the threaded connection, offers the advantage that the housing (for example, with a lid) can be closed, yet the drinking water safety device can still be connected. The housing or base then forms part of the inlet channel. Such a design is very easy to handle.

[0021] Preferably, the first opening is formed by a projection that extends upwards from the base and into which the drinking water safety device engages in a sealing manner. For connection, the drinking water safety device simply needs to be inserted into the projection. For sealing, it is proposed that an O-ring seal be located in the projection, positioned between the drinking water safety device and the projection. Preferably, the drinking water safety device has a vertical connection with which it engages the projection.

[0022] Preferably, the leakage channel is completely enclosed. This allows for a particularly slim and compact design.

[0023] A further development of the invention is characterized in that the leakage channel is extendable. Such a design is particularly advantageous as it can be adapted to various toilet bowls and toilet seats.

[0024] An advantageous embodiment is characterized in that the leakage channel has a projection firmly connected to the housing, in particular an integral part of the housing, and a sliding element sealed against the projection, which is displaceable relative to the projection. The sliding element is advantageously slidably mounted in the projection. Either the projection has a circumferential seal for sealing against the sliding element, or the sliding element has a circumferential seal for sealing against the projection. The seal can be located in a circumferential groove in each case.

[0025] When installing the drinking water protection system, its reliability must be ensured. Preferably, at least one primary support extends upwards from the ground, upon which the water protection system rests. This support also creates the minimum distance to the ground required in some countries.

[0026] Within the scope of the invention, a drinking water safety device is preferred in which, during operation, water is sprayed over a free space to supply the nozzle. Advantageously, the free space is arranged between the first support and a second support. The first and second supports define a leakage section into which leakage occurs. Preferably, the leakage section is in flow communication with the leakage channel.

[0027] The two recesses have already been explained above. These recesses can be designed as openings through which the inlet and outlet channels pass. Advantageously, the second recess is open towards the back of the toilet bowl. It is designed, for example, as an open slot (viewed from above). Such a design creates advantageous tolerances during the installation of the housing. This is particularly relevant when a hose is connected to the housing with a connector or union nut, as also explained above. The hose can, for example, be a pressure hose with metal reinforcement, which inherently requires a certain degree of rigidity. The recess also provides an advantageous mounting aid for such a hose.

[0028] The invention will now be explained in more detail with reference to preferred embodiments in conjunction with the attached drawing. The drawing shows: Fig. 1 in schematic representation a perspective view of a first embodiment of a toilet with toilet seat according to the invention; Fig. 2 in schematic representation a perspective view of the first embodiment without toilet seat; Fig. 3 in schematic representation the housing of the first embodiment in a view from a slant below; Fig. 4 in schematic representation a sectional view of the housing according to Fig. 3; Fig. 5 in schematic representation a partially disassembled view of the housing according to Fig. 3 in a view from a slightly oblique angle above; Fig. 6 in schematic representation a perspective top view of the lower part of the housing without drinking water protection; Fig. 7 in schematic representation a perspective view of the casing from a low angle; Fig. 8 in schematic representation a perspective view of the toilet from behind; Fig. 9 in schematic representation a second embodiment of a housing, wherein only the underside of the housing is shown in a perspective view; Fig. Figure 10 shows a schematic perspective view of the toilet according to the second embodiment from the rear; and Fig. 11 in schematic representation a perspective view of a toilet in which a cover is mounted instead of a drinking water safety device.

[0029] Fig. Figure 1 shows a perspective view of the toilet with bidet function according to the invention. The toilet has a toilet bowl 1 on which a toilet seat 2 is arranged. The toilet seat 2 is connected to the toilet bowl 1 by means of fastening means 3.

[0030] Reference numeral 4 designates an upper surface of the toilet bowl 1 on which the toilet seat 2 and a housing 5 are arranged. The upper surface 4 is preferably flat and horizontal.

[0031] Fig. Figure 2 shows the toilet bowl 1 without a toilet seat. It is clear from this that two openings 6 are formed in the top 4 for attaching the toilet seat.

[0032] The toilet bowl 1 has an interior space 7 and a nozzle 8 arranged within the interior space 7. The nozzle 8 is used for washing the human buttocks with water. Such an arrangement is also known as a Turkish toilet.

[0033] A leakage channel 9 extends from the housing 5, through which leaking water is directed into the interior 7. The leakage channel 9 extends across the interior 7, thus allowing the leakage to enter the interior 7. The leakage originates from a drinking water safety device, such as those used in connection with Fig. 5 will be explained in more detail.

[0034] Fig. Figure 3 shows the housing 5 in a view from a low angle. As can be clearly seen from this view, the leakage channel 9 is designed in two parts, which is considered advantageous in itself. The leakage channel 9 has a projection 10, which is preferably formed integrally with a lower part 11 of the housing 5. A sliding piece 12 is accommodated in the projection 10 and is slidable relative to it. The slidability of the sliding piece 12 allows the length of the leakage channel 9 to be adjusted so that it can be adapted to different toilet bowls. At the end of the leakage channel 9, or in this case at the end of the sliding piece 12, there is an outlet 13 for the leakage.

[0035] The housing 5 is preferably designed in two parts and, in addition to the aforementioned lower part 11, has a lid 14 which preferably engages with the lower part. The lower part 11 forms a base 15 from which two fastening devices 16 project, serving to fasten the housing 5 to the toilet bowl. The fastening devices 16 are designed as pins and each has two rubber ridges 17 that engage in corresponding recesses, as is the case with Fig. 8 will be explained in more detail.

[0036] Housing 5 contains a drinking water safety device, which is located in Fig. 3 is not visible due to the housing 5. A supply channel leads to the drinking water protection system, which in this case is provided by a metal-reinforced connection hose 18. The connection hose 18 is connected to a threaded connection 19 by means of a union nut 20.

[0037] The drinking water protection system is further connected to a drainage channel, which in this case is provided by a hose 21. For this purpose, the base 15 has a first opening 22 through which the drainage channel passes.

[0038] Fig. Figure 4 shows a sectional view through the housing 5 and the leakage channel 9. The sliding piece 12 is slidably mounted in the projection 10 and sealed against the projection 10 by a seal 23. The seal 23 can be designed as an O-ring.

[0039] To prevent the sliding piece 12 from being unintentionally pulled out of the projection 10, the projection 10 has a projection 24 which engages in a groove 25 (see Fig. 3) intervenes. Furthermore, it is considered advantageous if the approach 10 is integrally formed with the sub-part 11.

[0040] Fig. Figure 5 shows the housing 5 in an open state and without the sliding piece 12. The drinking water safety device 26, already mentioned, is arranged in the lower part 11 of the housing 5. Such a drinking water safety device 26 is known. The drinking water safety device is supported by two supports 27, which are preferably integrally formed with the lower part 11. The drinking water safety device 26 has a grid 28. In this area there is a (not visible) free space through which a water jet is sprayed. This free space is arranged (in a front view) between the two supports 27.

[0041] Out of Fig. Figure 6 shows that the inlet channel passes through a second opening 29 formed in the base 15. The second opening 29 is formed by a projection 30 extending upwards from the base 15. Reference numeral 31 indicates a seal that ensures a seal between the drinking water protection device 26 and the projection 30. The seal 31 may be designed as an O-ring. The outlet channel passes through the first opening 22, which is already mentioned in connection with Fig. 3 has been described. The first opening 22 is also formed in the floor 15.

[0042] How it looks Fig. As can be seen in Figure 7, the threaded connection 19 is integrally formed with the base 15. The second opening 29 preferably passes through the threaded connection 19.

[0043] Fig. Figure 8 shows the toilet from the rear. The toilet has a flushing water supply 32 and a wastewater drain 33. The two mounting holes 34 are used to attach the toilet bowl 1 to a wall. The attachment of a toilet bowl to a wall and the connection of the flushing water supply and the wastewater drain are known from the prior art.

[0044] The toilet bowl 1 has a first recess 35 and a second recess 36. The hose 21 extends through the first recess 35 and is connected to the nozzle 8 in a known manner. The inlet channel extends through the second recess 36. For this purpose, the metal-reinforced connecting hose 18 is connected to the housing by means of the union nut 20. The connecting hose 18 is supplied with drinking water in a known manner. Whenever drinking water is mentioned in this application, it refers to tap water from a domestic water supply. According to the invention, the first opening 22 and the first recess 35 are aligned. The hose 21 can therefore extend directly through the first opening 22 and the first recess 35 through the top surface 4 of the toilet bowl 1. According to the invention, the second opening 29 and the second recess 36 are also aligned.The inlet channel also advantageously runs from bottom to top directly through the top 4 into the housing 5. Advantageously, the second opening 29 is through the threaded connection 19 (. Fig. 7) formed. Furthermore, it is generally considered advantageous if the second recess 36 is open towards the rear of the toilet bowl 1, as is well done in Fig. 8 can be seen. The union nut 20 sits in the recess. The second recess 36, which is advantageously designed to be fully open to the rear, allows for easy assembly of the housing 5.

[0045] As in Fig. As shown in Figure 8, an advantageous embodiment is characterized in that the flush toilet has two mounting openings 34 and a flush water supply 32, wherein the first recess 35 is arranged on one side of the flush water supply 32 and the second recess 36 is arranged on the other side of the flush water supply 32. This particularly advantageously allows the drain channel to run between one mounting opening 34 and the flush water supply 32, and the inlet channel to run between the other mounting opening 34 and the flush water supply 32, thus creating advantageous space conditions.

[0046] To attach the housing 5 to the toilet bowl 1, the toilet bowl has two recesses 37 into which the fastening devices 16 engage. Preferably, the two recesses 37 are arranged laterally to the first recess 35 and the second recess 36.

[0047] It should be noted that the location given here refers to a toilet in its installed state, with the viewer standing in front of it. The front is the side facing the viewer. The back is the side facing away from the viewer, i.e., the mounting side of the toilet.

[0048] Fig. Figure 9 shows a second embodiment of the housing according to the invention. For clarity, the same reference numerals are used for structurally and / or functionally similar components as in the first embodiment, even if the specific design differs. Fig. Figure 9 shows only the lower part 11 of the housing. This part has a base plate 38, which forms the leakage channel 9. The leakage channel 9 is formed in one piece. The fastening devices 16 are designed as clamps that can engage the receptacles 37. The base plate 38 forms the first opening 22 and the two openings 29 through which the drain channel and the inlet channel pass. The inlet channel is formed by a hose 39 and the drain channel by a hose 40. The two hoses 39 and 40 are connected by a clamp connection to the drinking water safety device 26, which sits on four supports 27.

[0049] Fig. Figure 10 shows that the connecting hose 18 is connected to the hose 39. The hose 40 is connected to the nozzle in the usual manner.

[0050] Fig.Figure 11 shows a situation in which, instead of a drinking water safety device, a cover plate 41 is mounted on the top of the toilet bowl 1. The cover plate preferably engages in the receptacles 37 or the recesses 35, 36 for attachment. Such an arrangement can be used when a drinking water safety device is not desired. In this case, the cover plate 41 advantageously covers the receptacles 37 and the recesses 35, 36.
