SANITARY SYSTEM AND METHOD FOR MANUFACTURING AND OPERATION THEREOF

Description

[0001] The invention is arranged in the field of sanitary installations and the invention relates to a sanitary system, a method for producing or installing a sanitary system and a method for operating a sanitary system, in which the sanitary system has a collecting basin of a first device, which can be a sanitary device but does not have to be, and a cistern of a second device, which is a sanitary device, wherein the water consumption of the sanitary device is reduced by supplying a liquid, in particular water, which is collected in the collecting basin to the cistern.

[0002] Sanitary systems are known from the prior art in which a liquid is collected in a collecting basin and fed to a cistern of a sanitary facility, in particular the cistern of a toilet facility. In such sanitary systems according to the prior art, the collecting basin, or the device comprising the collecting basin, and the cistern, or the sanitary facility comprising the cistern, are manufactured in a coordinated manner.

[0003] In so-called Eco Bath systems, the collecting basin and cistern are typically implemented as an integral part of a complete sanitary system. The system disclosed in EP 2309064 A1 and the Eco Bath grey water recycling system designed by Jang Wooseok are examples of such complete sanitary systems.

[0004] CN 107882128 A and CN 108708439 A disclose examples of sanitary systems in which the cistern, or the sanitary fixture comprising the cistern, and / or the collecting basin, or the fixture comprising the collecting basin, are specifically designed for use in a sanitary system in which a liquid, typically water, is collected in the collecting basin and supplied to the cistern. In particular, the cistern itself and the sanitary installation comprising the cistern comprise elements specifically designed for the supply and use of the water collected in the collecting basin. In addition, these sanitary systems typically comprise a multitude of control components with movable and therefore fault-prone and maintenance-intensive elements.

[0005] Publication KR 2000 0009508 A describes a device for supplying a toilet cistern with domestic water from a sink. The device comprises a supply line leading from the sink's drain into the cistern. Furthermore, the device comprises a drain line serving as an overflow and connecting the cistern to a drain for discharging domestic water from the cistern.

[0006] Publication KR 2000 0020368 U discloses a system with a water tank installed between the sink and the toilet. The sink's drain line leads into the water tank. An overflow line leads from the water tank to a drain, and a supply line leads to the toilet cistern. The wastewater from the sink is collected in the water tank and pumped into the cistern via the supply line by a pump.

[0007] The publication KR 200 196 994 Y1 also describes a system for feeding the cistern of a toilet with waste water from a washbasin.

[0008] There is little teaching in the prior art in connection with sanitary systems in which a liquid is collected in a collecting basin and fed to a cistern of a sanitary device, in particular the cistern of a toilet facility, in which the collecting basin, or the device comprising the collecting basin, and the cistern, or the sanitary device comprising the cistern, do not have to be manufactured in a coordinated manner.These systems generally have even more control components with movable and therefore error-prone and maintenance-intensive elements than the sanitary systems that are implemented as a complete system and than the sanitary systems with a specifically implemented collecting basin, or specifically implemented device that has the collecting basin, and a specifically implemented cistern, or specifically implemented sanitary device that has the cistern.

[0009] Float valves, multi-way valves or user-operated controls are examples of such control components.

[0010] It is an object of the invention to provide a sanitary system which has a collecting basin of a first device and a cistern of a second device which is a sanitary device, wherein in particular the sanitary device is any commercially available sanitary device and which has a reduced water consumption thanks to the inventive integration into the sanitary system.

[0011] It is a particular object of the invention to provide such a sanitary system which does not have control components with movable elements which are in addition to the control components with movable elements of the first and second devices.

[0012] It is a particular object of the invention to couple the sanitary facility to the second facility via a passive level control.

[0013] Furthermore, it is an object of the invention to provide a method for producing or installing such a sanitary system and a method for operating such a sanitary system.

[0014] The objects are achieved with a sanitary system according to independent claims 1 and 2, a method for producing the sanitary system according to independent claim 10, and a method for operating the sanitary system according to independent claim 14. Advantageous further developments are claimed in the dependent claims.

[0015] In many embodiments, the first facility is also a sanitary facility. At least in this case, the first facility is any commercially available sanitary facility. However, the first facility may not be a sanitary facility per se, but rather, for example, a facility for collecting natural liquid resources, such as rainwater.

[0016] In the most illustrative embodiment, the second facility is a toilet facility and the first facility is a washbasin facility.

[0017] A facility, or rather a sanitary facility, is considered to be any commercially available facility if, with regard to its fluid supply and fluid removal, it does not contain any elements that go beyond what is usual for its intended use. This is especially the case if the facility is designed as a stand-alone facility.

[0018] Basically, the liquid is removed from a facility or device in which liquid is conveyed for a specific purpose via a connection point of the facility or device to a connecting pipe. The term "connecting pipe" refers to a pipe that is exclusive to a specific facility or device. The connecting pipe opens into a higher-level pipe, which can be, for example, a collecting pipe or a downpipe. The collecting pipe carries the liquid supplied from several connecting pipes. In a downpipe, the liquid supplied from one or more connecting pipes and / or one or more collecting pipes is carried. The downpipe—as the name suggests—is usually arranged vertically.

[0019] Collective lines and downpipes are typically installed on the building side. This means they are considered part of the building in which the primary service, secondary service, and sanitary system are installed.

[0020] The sanitary (second) facility is an example of a facility where the liquid is removed in the manner just described, i.e. via a connection point to a connecting pipe exclusively for the sanitary facility.

[0021] Depending on the implementation of the inventive idea in the sanitary system, the liquid drainage from the first device and / or the drainage device described below can also be carried out in the manner just described.

[0022] Passive level control is particularly effective when no control element needs to be switched or operated to regulate the inflow into and, if applicable, the outflow from the cistern. Any outflow controlled by the passive level control does not serve to flush the cistern, but rather to regulate the fluid level in the cistern. Passive level control is particularly effective when no moving parts are involved in the inflow and, if applicable, the outflow.

[0023] A sanitary system according to the invention comprises a first device with a collecting basin, a second device with a cistern and a connection point for a drain line, wherein the second device is a sanitary device. The sanitary system further comprises an inflow line for supplying liquid collected in the collecting basin to the cistern and a drain device, wherein the drain device does not have a movable element. In other words, the drain device is passively level-controlled.

[0024] In the sanitary system according to the invention, the drainage device defines a liquid level and the drainage device is designed to drain liquid present in the sanitary system via a second connection point different from the connection point of the second device as soon as a liquid level in the cistern reaches the liquid level defined by the drainage device.

[0025] The supply line is generally formed exclusively from one or more pipe elements, in particular pipes, for example, pipes such as those commonly used in sanitary facilities. In particular, apart from one or more optionally present siphons or bends, the supply line generally does not have a volume suitable for retaining or storing liquid. In particular, the supply line is not or does not include a tank or reservoir.

[0026] Furthermore, the inlet line generally does not include or house any additional components other than one or more pipe elements and, if applicable, fixing and sealing elements. As mentioned above, the flow of liquid collected in the sump via the inlet line into the cistern is passively level-controlled.

[0027] The drainage device is generally formed exclusively from one or more pipe elements, in particular pipes, for example pipes such as those commonly used in sanitary facilities. In particular, apart from one or more optionally present siphons or bends, the drainage device generally does not have a volume suitable for retaining or storing liquid. In particular, the drainage device is not or does not comprise a tank or reservoir.

[0028] Furthermore, the drainage device generally does not include or house any additional components other than one or more pipe elements and, if applicable, fixing and sealing elements. The drainage of liquid via the drainage device is, as mentioned, passively level-controlled.

[0029] The liquid in the sanitary system that is drained away via the drainage device is in particular liquid that is collected in the collection basin.

[0030] The fluid in the system is in particular fluid collected in the collection tank and optionally fluid supplied to the cistern via an optional fluid connection (usually a water connection), whereby the optional fluid connection is independent of the inlet line for supplying fluid collected in the collection tank.

[0031] The drain line is a drain line for the second facility, in particular the connecting line of the second facility. Depending on the type and design of the second facility, the sanitary system, and / or the building in which the sanitary facility is installed, the drain line can alternatively be a collecting line, a downpipe, or another line for discharging liquid.

[0032] In particular, the second connection point is not a connection point of the second device that is present in the original second device.

[0033] Typically, the second connection point is a connection point of the drainage device or the first facility.

[0034] The second connection point is also a connection point for a drain line. This drain line can be a drain line of the drainage device, a drain line of the first device, or the drain line to which the second device is connected via the connection point of the second device.

[0035] Regardless of whether the drain line to which the second connection point is connected is a drain line of the drainage device, a drain line of the first device, or the drain line to which the second device is connected via the connection point of the second device, the drain line to which the second connection point is connected can be, for example, a connecting line, a collecting line, a downpipe, or another line for discharging liquid.

[0036] If the drain line to which the second connection point is connected is a connecting line, it may in particular be a connecting line of the first device, a connecting line of the drainage device or the connecting line to which the second device is connected via the connection point of the second device.

[0037] If the drain line to which the second connection point is connected is a manifold, a downpipe or other line for discharging liquid, it may be the same manifold, downpipe or other line to which the second device is connected via its connection point.

[0038] Essential parts of the drainage device, in particular a line element of the drainage device, via which liquid is drained to the second connection point as soon as the liquid level in the cistern reaches the liquid level, are arranged completely or mostly outside the cistern and outside the second device.

[0039] Furthermore, the inlet pipe is arranged entirely or mostly outside the cistern and outside the second device.

[0040] In one embodiment, the second device is a stand-alone sanitary device in whose cistern an inlet pipe connection has been integrated.

[0041] In other words, the second facility is any standard sanitary facility.

[0042] In one embodiment, the second facility is a toilet facility. Alternatively, the first facility can be a washbasin facility.

[0043] The liquid collected in the collection table is primarily so-called grey water.

[0044] The second facility is, in particular, any commercially available stand-alone toilet facility. In addition, the first facility can be any commercially available washbasin facility, which can be a stand-alone washbasin facility.

[0045] Any standard stand-alone toilet facility typically includes the following elements: a cistern; a toilet bowl; a connection point through which the contents of the toilet bowl can be drained into the wastewater system of the building in which the toilet is installed by emptying the cistern; and a water connection through which the toilet facility can be connected to the central water supply of the building in which the toilet facility is installed.

[0046] The cistern typically has a single chamber to collect the water required for the flushing process. A single chamber is sufficient or even advantageous for the sanitary system because it allows the position of the supply line connection on the cistern to be freely chosen and / or implemented particularly easily.

[0047] Regardless of the type and implementation of the second device, in one embodiment the cistern has exactly one chamber for storing flushing fluid. This is particularly the case when the second device is a toilet facility and the cistern is the cistern of the toilet facility.

[0048] Regardless of the type and implementation of the second facility, the cistern may additionally or alternatively have an overflow independent of the drainage device, through which liquid, in particular flushing liquid (usually flush water), can drain from the cistern as soon as the liquid level in the cistern reaches an overflow level. This is particularly the case if the second facility is a toilet facility and the cistern is the cistern of the toilet facility.

[0049] The drainage of liquid via the overflow can take place in particular via the connection point of the second device.

[0050] In embodiments with such an overflow, the liquid level defined by the drainage device is usually vertically below the overflow level.

[0051] Regardless of the type and implementation of the second device, the cistern may have a level-controlled float valve, for example, a single level-controlled float valve, through which the flow of fluid, in particular flushing fluid (usually flushing water), is interrupted via a fluid connection (usually a water connection) independent of the inlet line for supplying fluid collected in the collection basin, as soon as the fluid level in the cistern reaches a float valve level. This is particularly the case if the second device is a toilet facility and the cistern is the cistern of the toilet facility.

[0052] In embodiments with such a level-controlled float valve, the liquid level defined by the drainage device is usually vertically above the float valve level.

[0053] In one embodiment, the cistern features both the aforementioned overflow and the level-controlled float valve for regulating the inflow via a fluid connection independent of the inflow line. In this embodiment, the fluid level defined by the drain device is generally located above the float valve level and below the overflow level.

[0054] This embodiment is particularly realized in sanitary systems in which the second facility is a toilet facility and the first facility is a washbasin facility.

[0055] Regardless of the type and implementation of the second device, the first device comprises a collection basin drain line in a variety of embodiments.

[0056] In a variety of embodiments, the collection basin drain line includes a siphon. The collection basin drain line may include a siphon, in particular, if the collection basin drain line is connected to a sewage system of the building in which the first device is installed in such a way that, without the siphon, unpleasant odors would be expected to escape via the collection basin drain line toward the collection basin, and / or if it cannot be ruled out that contamination could enter pipes and elements downstream of the collection basin drain line via the collection basin.

[0057] In a first group of embodiments of the sanitary system, in which the first device comprises the collecting basin and the collecting basin drain line comprises a siphon and the second device is realized in any of the embodiments described above or below, the inflow line for supplying liquid collected in the collecting basin is arranged downstream of the siphon in the flow direction of the liquid.

[0058] In this first group of embodiments, the passive level control of the drainage device and thus the definition of the liquid level by the drainage device can be realized as follows: The drainage device comprises a line element which is arranged on the inflow line or on the cistern in such a way that liquid flows away via this line element and the second connection point as soon as the liquid level is reached in the cistern.

[0059] In one embodiment, the arrangement of the line element on the inflow line or on the cistern, in particular the vertical position of an outlet into the line element, determines when liquid located in the inflow line or in the cistern flows out via the line element.

[0060] Alternatively or additionally, the pipe element can have a shape that determines when fluid in the supply line or cistern flows through the pipe element. This shape can, for example, have a culmination point and / or a step.

[0061] Regardless of the specific implementation of the line element, neither the line element itself nor the outlet into it has any moving part or switching control element.

[0062] In particular, only (exclusively) the arrangement of the pipe element on the inflow pipe or on the cistern, in particular the vertical position of an outlet into the pipe element, can determine when liquid located in the inflow pipe or in the cistern flows away via the pipe element and the second connection point.

[0063] Regardless of the specific implementation of the pipe element and its outlet, the liquid level defined by the drainage device can be determined solely by the vertical arrangement of the outlet or optionally by the shape of the pipe element.

[0064] Particularly in cistern embodiments that feature the previously described overflow independent of the drain device and / or the previously described level-controlled float valve for regulating the inflow of flush water via the second inlet line, the liquid level defined by the drain device must be precisely matched to the overflow level and / or the float valve level. Especially in these embodiments, it can therefore be advantageous if the outlet into the pipe element is located close to the cistern, integrated into a cistern wall, or arranged within the cistern. In other words, the outlet can be arranged on the cistern side and not on the collecting basin drain line side.

[0065] Irrespective of the specific implementation of the first device, the second device and the drainage device, the drainage device can be configured such that both the cistern and the collecting basin or the collecting basin drain line are siphoned relative to the second connection point, i.e. have a siphon.

[0066] In the first group of embodiments, i.e., embodiments in which the supply line for conveying liquid collected in the collection basin to the cistern is arranged downstream of the siphon, the first device is not modified in such a way that any changes to the siphoning on the collection basin side are required. However, depending on the design of the piping element, the sanitary system may have a siphoning on the cistern side that the second device does not originally have.

[0067] In embodiments of the first group of embodiments, the line element through which liquid flows via the second connection point as soon as the liquid level is reached in the cistern is siphoned relative to the cistern.

[0068] The siphon used for this purpose should ideally be accessible from the outside for maintenance and cleaning. For example, access can be ensured via the cistern.

[0069] Accordingly, the sanitary system may have a cistern-side siphon in the region of the connection point on the cistern, via which the pipe element is in direct or indirect fluid interaction with the cistern.

[0070] In embodiments in which the pipe element branches off from the inflow pipe, the inflow pipe can form the cistern-side siphon.

[0071] Not only, but particularly in embodiments with an inflow line forming a siphon on the cistern side, the inflow line can open into the cistern in the base of the cistern or in an area of ​​a side wall of the cistern that is immediately adjacent to the base.

[0072] In other words, in some embodiments, the inflow line opens into the cistern in the base area of ​​the cistern. The first device, the second device, the drainage device, and the inflow line can be implemented in any of the ways described above or below.

[0073] Additionally or alternatively, and again regardless of how the first device, the second device, the drainage device, and the inflow line are specifically implemented, the cistern can have exactly one connection point via which the cistern is connected to both the inflow line and the drainage device. In other words, the second device can have exactly one additional connection point compared to its stand-alone state.

[0074] In embodiments in which the cistern has exactly one connection point via which the cistern is connected to both the inflow line and the outflow device, a line element of the outflow device can be arranged via an outlet on the inflow line, for example as described above and below.

[0075] In embodiments in which the pipe element leads directly from the cistern, the pipe element can form the cistern-side siphon.

[0076] In order to ensure the aforementioned accessibility of the cistern-side siphon via the cistern, the cistern-side siphon can have a bend which is realized by a pipe element arranged in the cistern, which can be separated from the inflow pipe or the pipe element via an interior region of the cistern.

[0077] The bend mounted on the inflow pipe or pipe element projects upwards in the cistern away from the inflow pipe or pipe element so that it - alone or in combination with another bend in the inflow pipe or pipe element - can ensure the siphoning of the pipe element relative to the cistern.

[0078] In one embodiment, the cistern-side siphon is arranged entirely within the cistern.

[0079] If the pipe element branches off from the inflow pipe, the previously described outlet from the inflow pipe into the pipe element can be arranged in the cistern.

[0080] In a second group of embodiments of the sanitary system, in which the first device comprises the collecting basin and the collecting basin drain line comprises a siphon and the second device is realized in any of the embodiments described above or below, the inflow line for supplying liquid collected in the collecting basin, more precisely its inflow line-outflow on the collecting basin drain line, is arranged upstream of the siphon of the collecting basin drain line in the flow direction of the liquid.

[0081] In embodiments according to the second group, the collection basin drain line can therefore have an inlet line outlet in the flow direction of the liquid collected in the collection basin. The collection basin drain line can be closed vertically below the inlet line outlet so that liquid collected in the collection basin, which flows out via the collection basin drain line, flows into the inlet line and thus toward the cistern.

[0082] In the embodiments according to the second group, the passive level control of the drainage device and thus the definition of the liquid level by the drainage device can also be defined by the arrangement of a line element of the drainage device. This can, for example: Be arranged on the inlet line or on the cistern, as disclosed in connection with embodiments according to the first group. However, it is important to ensure that the collection basin, or the area of ​​the collection basin drain line immediately adjacent to it, is also siphon-sealed relative to the second connection point. This can be achieved, for example, by the line element of the drainage device having a siphon or by the line element of the drainage device opening into the second connection point via the siphon of the collection basin drain line. If the line element of the drainage device opens into the second connection point via the siphon of the collection basin drain line, the collection basin drain line can have a line element inlet that is arranged upstream of the siphon of the collection basin drain line in the flow direction of the liquid flowing out via the line element.In particular, the line element inlet can be located downstream of the inlet line outlet or the closure of the sump drain line in the vertical direction along the original sump drain line. The original sump drain line is the sump drain line that the first device would have if it were installed as a stand-alone device. The line element of the drain device that defines the liquid level in the cistern extends only from one line element outlet on the sump drain line to the second connection point, wherein the line element outlet on the sump drain line is arranged in the vertical direction in such a way that it defines the liquid level and / or wherein the line element has a shape that determines when liquid flows through the line element.This shape can, for example, have a culmination point and / or a step. In such embodiments, the liquid collected in the collection basin and / or liquid supplied via the liquid connection independent of the inflow line for supplying liquid collected in the collection basin, if such a liquid connection is present, backs up in the inflow line back into the collection basin drain line because neither the inflow line nor the cistern has a line element through which liquid can flow towards the second connection point. Accordingly, the drain via the line element drain and / or the line element defines the liquid level, upon reaching which liquid in the cistern in the sanitary system is drained via the second connection point.In such embodiments, the pipe element can have a siphon, whereby both the collecting basin or the collecting basin drain line and the cistern opposite the second connection point are siphoned by a single siphon.

[0083] In a third group of embodiments of the sanitary system, in which the first device comprises the collecting basin and the collecting basin drain line comprises a siphon, and the second device is implemented in any of the embodiments described above or below, the inflow line for supplying liquid collected in the collecting basin, more precisely its inflow line outflow on the collecting basin drain line, is arranged upstream or downstream of the siphon of the collecting basin drain line in the flow direction of the liquid, wherein the inflow line outflow is arranged vertically below a level above which liquid flows out of the collecting basin drain line in the direction of the second connection point. In other words, said level defines the liquid level in the cistern, above which level liquid in the cistern in the sanitary system is drained via the second connection point.Accordingly, the installation of the first device can be such or adapted such that the desired liquid level is set above the level at which liquid flows from the collection basin drain line towards the second connection point.

[0084] Also in the third group of embodiments, the liquid collected in the collecting basin and / or the liquid supplied via the liquid connection independent of the inflow line for supplying liquid collected in the collecting basin, if such a liquid connection is present, accumulates in the inflow line back into the collecting basin drain line, because neither the inflow line nor the cistern has a line element via which liquid can flow away in the direction of the second connection point.

[0085] In one embodiment of the sanitary system, the collecting basin is siphoned opposite the cistern. For example, the collecting basin drain line can have a siphon and the inflow line for supplying liquid collected in the collecting basin can be arranged downstream of this siphon in the flow direction of the liquid.

[0086] Alternatively or additionally, the inflow line may have a siphon, in particular a cistern-side siphon.

[0087] In all embodiments of the sanitary system described above and below, the inflow line and / or the outflow device can be implemented entirely or substantially as a concealed and / or cavity installation.

[0088] "Essentially implemented as a concealed and / or cavity installation" means, in particular, that the inlet line and / or the outlet device are implemented as a concealed and / or cavity installation, except for one or more connections on the cistern and / or one or more connections on the first device, in particular on the sump drain line. It goes without saying that in addition to an exposed connection, a section of the line is usually also exposed, extending from the connection to a position where the concealed and / or cavity installation begins.

[0089] Implementing the inflow line and the outflow device as a fully or substantially flush-mounted and / or cavity installation results in a visually high-quality impression, with no noticeable change to the first and second devices compared to their stand-alone state. Furthermore, the pipe routing in embodiments in which the inflow line and the outflow device are fully or substantially flush-mounted and / or cavity installations are such that a very high level of reliability is guaranteed. Furthermore, no intentional or unintentional tampering by a user unfamiliar with sanitary systems can occur.

[0090] Alternatively, in all embodiments of the sanitary system described above and below, the inflow line and / or the outflow device can be realized entirely or substantially as a surface-mounted installation, i.e. exposed.

[0091] "Substantially implemented as a surface-mounted installation" means, in particular, that the supply line and / or the drainage device are implemented as a surface-mounted installation except for one or more connections, in particular the second connection point. It goes without saying that in addition to a non-exposed connection, a section of the line extending from the connection to a position where the surface-mounted installation begins is also usually not exposed.

[0092] Particularly in embodiments according to the first group, the inflow line and the outflow device are preferably implemented entirely or substantially as a concealed and / or cavity installation. This also means that a sanitary system according to the first group of embodiments is preferably implemented during the installation of the first and second devices. Implementation at a later time, i.e., after the first and second devices have been installed as stand-alone devices, and / or an implementation in which the inflow line and the outflow device are implemented entirely or substantially as a surface-mounted installation, is also possible.

[0093] The invention further relates to a method for producing a sanitary system according to the invention in any of the aforementioned embodiments. Since a system according to the invention generally consists of a first device designed as a stand-alone device and a second device that is a sanitary device and is designed as a stand-alone device, the method for producing a sanitary system according to the invention in any of the aforementioned embodiments can, in many embodiments, correspond to a method for installing a sanitary system according to the invention in any of the aforementioned embodiments or to a method for converting an installed first device and an installed second device to a sanitary system according to the invention in any of the aforementioned embodiments.

[0094] A method for producing a sanitary system comprising a first device with a collecting basin, in particular a first device in one of the previously described embodiments, and a second device with a cistern and a connection point for a drain line, in particular a second device in one of the previously described embodiments, wherein the second device is a sanitary device, comprises the following steps: Installation of an inlet line for supplying fluid collected in the collection basin to the cistern. Provision of a drainage device that has no movable element and defines a fluid level. The drainage device provided is further configured to drain fluid in the sanitary system via a second connection point different from the connection point of the second device as soon as the fluid level in the cistern reaches the fluid level.

[0095] The drainage device provided is in particular designed and integrated into the sanitary system in such a way that liquid in the sanitary system is drained via the second connection point, which is different from the connection point of the second device, as soon as a liquid level in the cistern reaches the liquid level.

[0096] In one embodiment of the manufacturing method, it is carried out during the installation of the first and second devices in the building in which the sanitary system is to be installed. In this case in particular, the manufacturing method can be considered the aforementioned method for installing the sanitary system.

[0097] Alternatively, the manufacturing process is carried out after the first and second devices have been installed in the building. Especially in this case, the manufacturing process can be considered the aforementioned process for converting the first and second devices to the sanitary system.

[0098] Regardless of the time of application of the manufacturing process, the second device may be a stand-alone sanitary device in whose cistern an inlet pipe connection is integrated during the process.

[0099] In particular, the second connection point is not a connection point of the original second facility.

[0100] Regardless of the time of application of the manufacturing process and whether the second device is a stand-alone sanitary device, the cistern is usually connected to the second connection point via the drainage device.

[0101] In addition, the inflow line connection is integrated into the cistern, whereby the cistern can be connected to the second connection point via the inflow line connection and the drain device.

[0102] Typically, the first facility, in particular its collection basin or its collection basin drain line, is also connected to the second connection point or remains connected to it. This is particularly the case if the second connection point was and remains a drain line connection point of the first facility. However, the way in which liquid collected in the collection basin flows toward the second connection point can be changed during the process.

[0103] In one embodiment, a line element connecting the collecting basin to the second connection point is modified such that a first region of the line element merges into the inflow line and that a line element of the drainage device, via which liquid flows out via the second connection point as soon as the liquid level in the cistern is reached, merges into a second region of the line element.

[0104] The first area of ​​the line element is located upstream of the second area of ​​the line element in the direction of flow.

[0105] These transitions can be realized by two connection points on the pipe element connecting the collection basin to the second connection point. Additionally, a section of the pipe element between the connection points can be removed or sealed off.

[0106] If the manufacturing process is carried out during the installation of the first and second devices in the building, a pipe element connecting the collection tank to the second connection point can be directly installed, modified as described above.

[0107] The manufacturing method may comprise a step in which an inspection opening is provided, wherein a connection point, in particular one or both of the aforementioned connection points, is accessible via the inspection opening.

[0108] The invention further relates to a method for operating a sanitary system according to independent claim 14.

[0109] The operating procedure includes the following steps: Directing the liquid collected in the collection tank to the cistern. Draining the liquid in the sanitary system via a second connection point, which is different from the connection point of the second device, as soon as the liquid level in the cistern reaches a certain level. The drainage of the liquid in the sanitary system occurs via a drainage device that has no moving element and that defines the liquid level.

[0110] In one embodiment, the second connection point is not a connection point of the original second device. In this embodiment of the operating method, the cistern is connected to the second connection point via the drainage device.

[0111] Exemplary embodiments of the invention are described below with reference to the figures. They show: Figure 1A schematic representation of an exemplary sanitary fixture according to the invention that is installed; Figures 2a-2b A schematic detailed view of the sanitary facilities according to Fig. 1 before ( Fig. 2a ) and after ( Fig. 2b ) Realization of the inventive idea; and Figures 3-8 Schematic representations of further exemplary sanitary facilities according to the invention.

[0112] Figure 1 shows a schematic representation of an exemplary sanitary device according to the invention, which falls under the first group of embodiments described above.

[0113] Shown is the first device 60, which in the embodiment shown is a washbasin system comprising a collecting basin 3 and a collecting basin drain line 25.

[0114] In the embodiment shown, the collecting basin drain line 25 has a siphon 26 even after the realization of the inventive idea.

[0115] Furthermore, the second sanitary device 50 is shown, which in the embodiment shown comprises a WC system comprising a cistern 1 and a WC bowl 2. The cistern 1 in the embodiment shown has the optional features of a pre-installed overflow 16 and a pre-installed water supply line 40 (in Figure 1 not visible). The water flow via the pre-installed water supply line 40 is regulated by a level-controlled float valve 11 with a float 11.1 and a valve 11.2.

[0116] The sanitary system further comprises an inflow line 21 and a drainage device 6. In the embodiment shown, the inflow line 21 and the drainage device 6 are arranged completely "concealed." This means that the inflow line 21 and the drainage device 6 are arranged behind a wall element 7 from a user side of the sanitary system. To visualize the inflow line 21 and the drainage device 6, the wall element 7 is Figure 1 partially omitted.

[0117] The inflow line 21 is connected on one side to the collecting basin 3 via the collecting basin drain line 25 and on the other side to the chamber of the cistern 1 via an inflow line connection 15 on the cistern 1. The inflow line 21 is thus configured to supply water collected in the collecting basin 3, in particular water collected in the collecting basin 3 during handwashing, to the cistern 1.

[0118] In the embodiment shown, the drainage device 6 has a line element 24. On one side, this is connected via an outlet 22 from the inflow line 21 to a portion 20 of the inflow line 21 and thus to the cistern 1. On the other side, the line element 24 is connected to a connection point 5 on a collecting line 14. In other words, fluid flows via the drainage device 6 only toward this so-called second connection point 5, but not via a connection point 4 of the toilet facility. Figure 2b shows in detail how the line element 24 is arranged.

[0119] In the Figure 2bIn the embodiment shown, connection point 5 is connection point 8 of the original washbasin system. In alternative embodiments, connection point 5, to which the conduit element 24 leads, will be a different connection point from the realized or intended connection point 8 of the original washbasin system, wherein connection point 8 of the original washbasin system is closed or not realized.

[0120] In the embodiment according to Figure 1 (and Figure 2b) the inventive idea is realized in that neither the inflow line 21 nor the line element 24 nor the outlet 22 nor the inflow line connection 15 have any movable or regulating element. Rather, the said components are arranged relative to one another in such a way that the liquid level in the cistern 1 and in the inflow line 21 is the same. As soon as the liquid level in the cistern 1 and in the inflow line 21 has reached the level of the outlet 22, liquid flows out of the sanitary system via the line element 24 automatically and without any movement or switching process. As a result, the liquid level in the cistern no longer rises and there can be no backflow of liquid into the collecting basin drain line 25 or even into the collecting basin 3.

[0121] In other words, the outlet 22 defines a liquid level 240 in the cistern 1 and the drainage device 6 is designed to drain liquid in the sanitary system via the line element 24 and towards the second connection point 5 as soon as the liquid level in the cistern 1 reaches the liquid level 240.

[0122] In the Figure 1 (and Figure 2b ) the drainage device 6 thus has, in addition to the line element 24, the outlet 22 and the partial area 20 arranged between the outlet 22 and the cistern 1, including the area projecting into the chamber of the cistern 1, the inflow line 21.

[0123] Not only in the Figure 1shown embodiment, but in general, the inflow line 21 is also arranged such that the supply of liquid collected in the collecting basin 3 to the cistern 1 also takes place automatically and without manipulation of a movable element, be it by a user or by a mechanism inherent in the sanitary system. For this purpose, the first device, namely the collecting basin 3, and the second device, in particular the cistern 1, must be arranged accordingly relative to one another, i.e., the collecting basin 3 must be arranged vertically above the desired liquid level 240.

[0124] In a sanitary system, a first device 60, which may be a washbasin system, and a second device 50, which may be a toilet system, are used, wherein the first and second devices may be commercially available devices designed as stand-alone devices and possibly already installed in a room of a building.

[0125] Figure 2a shows, using the example of a washbasin system 60 and a toilet system 50, how such commercially available first (washbasin system 60) and second (toilet system 50) facilities designed as stand-alone facilities can be installed or can be intended for installation before the inventive idea is implemented.

[0126] The wash basin system 60 has the collecting basin 3, the collecting basin drain line 25 with the siphon 26 and a wash basin connection point 8.

[0127] The toilet system 50 comprises the cistern 1, the water supply line 40, the toilet bowl 2 (not shown) and a toilet connection point 4.

[0128] In the embodiment shown, the washbasin connection point 8 is a connection point to a collecting line, and the toilet connection point 4 is a different connection point from the washbasin connection point 8 to the same collecting line. Alternatively, the washbasin connection point 8 can be, for example, a connection point for a washbasin connection line, and / or the toilet connection point 4 can be, for example, a connection point for a toilet connection line.

[0129] The washbasin system 60 and the toilet system 50 do not interact with each other. In particular, fluid located anywhere in the washbasin system 60 cannot reach the toilet system 50, in particular its cistern 1, and fluid located anywhere in the toilet system 50, in particular its cistern 1, cannot reach the washbasin system 60, in particular its connection point 8.

[0130] Both Figures 2b-7 It should be noted that for better visualization, the sanitary system is shown in one plane, although parts of it, in particular the collecting basin 3 and the collecting basin drain line 25 ( Figure 2b ), the pipe element 24 of the drainage device 6 and the wall element 7 ( Figures 3-5 ), or the drain-side part of the siphon 26 of the collecting basin drain line 25 and the wall element 7 ( Figures 6 and 7 ) in the viewing direction from the plane of the sheet to the front ( Figure 2b) or backwards ( Figures 3-7 ) would stand out.

[0131] Figure 2b shows the Figure 2a Washbasin unit 60 shown and the one in Figure 2a shown WC facility 50 in its form realized as a sanitary system according to an exemplary embodiment of the inventive idea.

[0132] The Figure 2b The design of the sanitary system shown corresponds to the one in Figure 1 shown embodiment. In comparison to Figure 1 is in Figure 2b Additionally, the connection of the line element 24 to the second connection point 5, which in the embodiment shown corresponds to the original washbasin connection point 8, is visible. Furthermore, the regions 13 are schematically indicated in which a line element of the washbasin system 60 was removed and to which the inflow line 21 and the line element 24 of the drainage device 6 were connected.

[0133] Due to the way in which the second connection point 5 is connected to the cistern 1, the inflow line 21, and thus the outflow device 6, has a siphon 23 via which it is connected to the chamber of the cistern 1.

[0134] In the embodiment shown, the siphon 23 has a first bend 23.1 that can be removed from the inlet line 21. This bend can be removed via the chamber of the cistern 1, allowing the siphon 23 to be serviced via the chamber of the cistern 1.

[0135] In the embodiment shown, the siphon 23 further comprises a bend 23.2 which is not designed to be removed beyond the chamber of the cistern 1.

[0136] The Figures 3-7 show alternative exemplary realizations of the sanitary facility: Figure 3shows an embodiment in which the line element 24 of the drainage device 6, whose arrangement in the sanitary system ultimately defines the liquid level 240, extends only from one line element outlet 30 on the collection basin drain line 25 to the second connection point 5 (not shown). The liquid level 240 is defined by the vertical arrangement of the line element outlet 30. Figure 4 showed an embodiment according to Figure 3 , but the liquid level 240 is not defined by the vertical arrangement of the line element outlet 30, but by the shape of the line element 24. In the embodiment shown, this has a vertically upwardly directed arc, which forms a culmination point 32, which defines the liquid level 240. In Figure 4 The original course of the collection basin drain line 24 is indicated by dashed lines. Figure 4 one of the Figures 1-3alternative realization of the inflow line connection 15 on the cistern 1 and an associated alternative design of the inflow line 21 are shown with dashed lines. Figure 5 shows an embodiment according to the previously described third group of embodiments, in which the liquid level 240 is ultimately defined by the vertical position of the second connection point 5 on a drain line. In the embodiment shown, the drain line 14 is a downpipe. In the embodiment shown, the pipe element drain 30 is located downstream of the siphon 26 of the collection basin drain line 25, and the cistern 1 is siphon-sealed relative to the inflow line 21. Alternatively, the pipe element drain 30 can be located upstream of the siphon 26 of the collection basin drain line 25. In this case, it is not necessary to siphon the cistern 1 relative to the inflow line 21. Figure 6shows an embodiment in which the inflow line 21 branches off from the collection basin drain line 25 at an inflow line-outflow 31, wherein the inflow line-outflow 31 is located upstream of the siphon 26 of the collection basin drain line 25 in the flow direction of the liquid collected in the collection basin 3. Figure 6 This is therefore an embodiment according to the second group of embodiments described above. In the embodiment according to Figure 6 Furthermore, the collecting basin drain line 25 is closed below the inflow line drain 31 and the line element 24 of the drain device 6 also opens into the collecting basin drain line 25 before the siphon 26. Analogous to the Figures 1 and 2a The embodiments shown are also shown in Figure 6 shown embodiment, the liquid level 240 is defined via an outlet 22 of the line element 24 from the inflow line 21. In Figure 6Furthermore, an alternative embodiment is shown in dashed lines, in which the liquid level 240 is defined by the shape of the conduit element 24. The conduit element 24 has a culmination point 32 that defines the liquid level 240. Figure 7 shows an embodiment which differs from the embodiment according to Figure 6 differs in that the pipe element 24 has its own connection (pipe element connection 28) on the cistern 1. The liquid level 240 is therefore defined by the vertical position of the pipe element connection 28. In the embodiment according to Figure 7In particular, a siphon connection of the line element 24 and the inflow line 21 to the cistern 1 can be dispensed with because the inflow line 21 and the line element 24, or the outflow device 6, are shielded by the siphon 26 from the second connection point 5 (not shown). The same also applies to the Figures 3, 4, 5 (if the pipe element drain 30 is arranged in front of the siphon 26) and 6. Therefore, even in these embodiments, a siphon-type inflow line 21 and a siphon-type pipe element 24 can be dispensed with on the cistern side. Figure 8shows an embodiment in which a cistern-side siphon 23 is arranged entirely within the cistern 1. This improves, for example, the accessibility of the siphon 23 for cleaning and maintenance purposes and can simplify the implementation of the sanitary system. The inlet line connection 15 on the cistern 1 and the optionally present line element connection 28 on the cistern 1, depending on the arrangement of the line element 24 of the drainage device 6, are selected according to the arrangement of the cistern-side siphon 23. In the Figure 8 shown embodiment, in which the drainage device 6, apart from its arrangement with the cistern-side siphon 23 located in the cistern 1, of the type shown in Figure 2b shown embodiment, the cistern 1 has both the inflow line connection 15 and the line element connection 28.
