Description

[0001] The invention relates to a toilet system which, through the interaction of several inventive functional systems, enables a significant reduction in water consumption and makes toilet paper unnecessary, equipped with a multifunctional seat ring for a water closet, which is pivotable, preferably connectable to the closet body, and usable in both private and public toilet arrangements.

[0002] Most modern toilets are flushed with drinking water. Only a few facilities have a separate greywater system used for toilet flushing. The increasing scarcity of this precious resource is forcing us as a society to conserve water. This is especially true regarding the waste of drinking water in toilet flushing.

[0003] The drinking water situation cannot be viewed solely from the perspective of fresh water. There is an equally important dimension to consider: wastewater. After all, in wastewater treatment plants, over 99% of the wastewater is mechanically and biologically purified using bacterial cultures before being discharged back into rivers and thus reintroduced into the drinking water cycle. However, this purification process leaves behind chemical substances such as the persistent PFAS (polycyclic aromatic hydrocarbons) in the treated water, rendering it unsuitable for long-term drinking water use.

[0004] Scientists have discovered an unexpected source for the entry of these chemicals into wastewater systems: toilet paper. Toilet paper is contaminated by 6:2 di PAP during the production process of converting wood into paper. France currently has the most extensive research into PFAS contamination. A full 89% of PFAS contamination in French wastewater is caused by di PAPs from toilet paper. This problem is expected to occur worldwide.

[0005] Another problem in wastewater systems and sewage treatment plants is the quality and availability of toilet paper. PFAS-free toilet paper is now available as a niche product, for example made from bamboo fibers for environmentally conscious consumers. However, this does not solve the problem for society as a whole worldwide.

[0006] Even the "moist toilet paper" version poses problems for wastewater systems. It doesn't dissolve as quickly and can cause blockages in toilets and sewage systems. However, a much bigger, indirect problem for wastewater treatment plants is the availability of toilet paper to consumers. If there's no toilet paper in the household, all sorts of materials are misused as toilet paper and flushed down the toilet. Moist wipes and even textiles, for example, increasingly ended up in sewage systems during the COVID-19 pandemic. They not only clogged toilets but also the pumps in wastewater treatment plants.

[0007] As the coronavirus pandemic taught us, toilet paper suddenly experienced supply problems, partly triggered by panic buying by consumers. This also demonstrates the vital importance of the availability of this product in everyday life.

[0008] The toilets with a water flush, also known as flush toilets or WCs, which have been standard for many decades, consist of a toilet bowl on whose upper rim a hinged toilet seat, also called a toilet lid, rests. A similarly hinged toilet cover rests against the toilet seat when the toilet is closed.

[0009] Human waste entering the toilet bowl during use is flushed into the sewer system via a siphon integrated into the toilet body. The flushing water is supplied at the upper inner rim of the toilet bowl, either by releasing a water reservoir stored in a cistern or by directly connecting the toilet bowl to a water supply network. In the latter case, the flushing process is initiated by activating a pressure flush valve. The flushing water running down the inner surfaces of the toilet bowl is often insufficient to ensure the necessary cleaning of soiled areas, even after multiple flushes with high water consumption.In this case, the cumbersome and unpleasant use of a toilet brush is required, which is extremely unhygienic, as fecal residue can stick to the toilet brush and bacterial contamination of such brushes is practically the norm.

[0010] Keeping toilet facilities clean in public areas is particularly problematic, as they are accessible to an uncontrolled group of people and the necessary, proper manual cleaning, including the removal of blockages, can only be achieved with high personnel and financial resources, which are usually not available.

[0011] From DE 199 08 779 A1, a device for the internal cleaning of a toilet bowl is known, comprising a toilet seat designed as a hollow body with a central opening and a cleaning element supplied with flushing water that can be moved into the toilet bowl from a position below the opening via a telescopic tube or a bellows. Comprehensive hygienic toilet cleaning is not possible with this device.

[0012] From DE 10 2007 060 698, a toilet arrangement is known with a toilet bowl, a hinged toilet lid, and a seat ring, wherein the toilet lid is designed as a hollow body with an opening facing the toilet bowl in the closed position. The toilet lid incorporates a motor-driven actuating mechanism for a cleaning nozzle body that can be moved into the toilet bowl and is connected via a flexible line and a pump to a cleaning fluid reservoir for cleaning the inner walls of the toilet bowl. In the lid position, which can be moved into a closed and locked position by the motor, the inner walls of the toilet bowl are additionally cleaned after the normal flushing process.

[0013] In this known arrangement, a ring-shaped channel with spray and air nozzles is integrated into the annular base of the toilet seat. This allows a cleaning fluid to be sprayed onto the seat ring via a supply channel and a pump from a cleaning agent reservoir, and the seat ring is then dried with warm air. These known devices are not only extremely complex and bulky, but they are also unsuitable for eliminating the fundamental problems of toilet systems with a water reservoir stored in a cistern, their susceptibility to malfunctions due to limescale buildup, and, above all, the extreme soiling and blockages that occur in public toilet facilities.

[0014] The object of the present invention is, in particular, to design a toilet seat ring and a toilet assembly equipped with it in a structurally simple manner, such that, in conjunction with all the functions implemented, lasting cleanliness and the highest level of hygiene can be guaranteed, along with high reliability and low maintenance. Furthermore, water consumption should be reduced and toilet paper rendered unnecessary. According to the basic concept of the invention as defined in the claims, the toilet seat ring is assigned a plurality of nozzles possessing cleaning and / or drying functions, wherein the controllable supply of media in the form of water and / or compressed air to the nozzles depends on the pivoting position of the seat ring.

[0015] To eliminate the need for toilet paper, a basic embodiment of the invention allows for the implementation of a toilet seat with an integrated bidet function, independent of the flushing technology used in the toilet arrangement. This is achieved by molding opposing projections on the underside of the toilet seat, preferably at the front and rear. These projections are preferably fitted with horizontally oriented nozzles that can be supplied with tempered high-pressure water or compressed air. The preferred use of water spray nozzles in conjunction with the compressed air nozzles for drying in seconds reduces the time required for this convenient cleaning process to the usual minimum. This is a key benefit for the acceptance of the paperless system.

[0016] This eliminates the need for any separately movable, complicated shower elements of the conventional type and creates a defined washing and drying level that is always limited to the area of ​​the toilet seat and offers a high level of user comfort.

[0017] To reduce water consumption, a particularly advantageous embodiment of the invention provides a plurality of high-pressure nozzles distributed across the underside of the toilet seat ring, the jet directions of which are directed towards the inner wall surfaces of the toilet bowl, these high-pressure nozzles forming a high-pressure flushing device that can be connected to a domestic water supply via channels in the toilet seat ring and triggered in a controlled manner, ensuring very efficient cleaning without the previously usual manual rework using a toilet brush. The controllable media supply to the nozzles in the seat ring is achieved in particular via a pivot axis arrangement that can be connected to the toilet body.

[0018] The design of the WC hybrid seat as a multifunctional unit with integrated nozzles, especially high-pressure nozzles, and the possibility of supplying these nozzles with water from the domestic water supply and / or compressed air generated by a quiet air compressor, makes it possible to create a self-cleaning, rimless toilet arrangement without complicated and failure-prone moving elements, which also opens up fundamentally new possibilities for the design of the arrangement and allows for diverse design variations.

[0019] By connecting directly to the mains water supply and using suitable control valves, not only is the conventional cistern with its stored water reservoir and the associated, limescale-prone functional components eliminated, but optionally the flushing water connection on the toilet body is also eliminated, resulting in a less complex toilet bowl and thus potentially simplified manufacturing and enabling optimized, varied designs.

[0020] The use of a "whisper-quiet" and inexpensive air compressor, possibly in conjunction with a compressed air storage tank, not only has the advantage that the nozzles provided in the toilet seat with bidet function can be supplied with air or even heated air, but also creates the possibility of providing a hand drying station with appropriately connected compressed air nozzles adjacent to the toilet arrangement via compressed air lines.

[0021] While known solutions for so-called shower toilets involve very time-consuming cleaning and drying processes, either using additional attachment elements or complicated and also failure-prone parts such as shower heads and pipes with warm air outlets, the invention makes it possible to realize all known bidet functions without any moving components that can be moved by means of drives.

[0022] The nozzles integrated into the front and rear of the toilet seat allow for the selective generation of either temperature-controlled, high-pressure water or temperature-controlled compressed air. The combination of water, preferably sprayed from nozzles, with the rapid drying provided by compressed air significantly reduces the cleaning time to the usual short process. This offers a significant benefit for the widespread acceptance of paperless toilets and contributes to a PFAS-reduced drinking water cycle. Since the generated water jets are essentially horizontal and thus always remain within the toilet seat opening, the risk of water splashing out due to improper handling, which is quite possible with conventional designs, is eliminated.

[0023] The simple design of the toilet seat's multifunctionality is primarily ensured by its preferably two-part construction: a die-cast aluminum base and a plastic upper part. Together, these two parts form the channels for water and air, which are supplied separately from either side of the seat's pivot axis. The pivot axis is preferably designed such that, depending on the seat's position, it creates valve functions for the supplied media. For example, in bidet mode, one side of the axis can be supplied with tempered, moderately high-pressure water for washing, while the other side can be supplied with compressed air for drying.

[0024] When the hybrid seat is fully equipped, one side of the centrally divided hollow shaft is connected to the high-pressure water supply for the rinsing nozzles. The other side, or the other inlet, is for the bidet function, using the same nozzles sequentially with tempered high-pressure water for washing and compressed air for drying. A media diverter valve is used to achieve this function.

[0025] A further advantage of the invention is that the toilet bowl can be designed without a rim, i.e., in particular without any horizontal and vertical upper boundary surfaces. These horizontal edge surfaces become soiled on both sides and are poorly or not at all reached by conventional flushing systems, requiring regular manual cleaning. With the high-pressure nozzles provided in the toilet seat ring, all surfaces of the toilet bowl can now be cleaned very effectively with directed jets in the rimless design. It is also possible to provide at least one high-pressure surface nozzle with centrally symmetrical, wall-adjacent side outlets in the rear upper central area of ​​the toilet bowl for surface wall rinsing.

[0026] Regardless of the constraints on water flow of previously known flushing systems, the completely rimless design enables optimal and easy cleaning.

[0027] The multifunctional toilet seat ring according to the invention, which can be used independently for differently designed, conventional toilet arrangements, unfolds its full advantages in conjunction with other inventive elements of the flushing system in its use in a toilet arrangement in which the flushing device formed by high-pressure nozzles can be connected to a domestic water supply line and in which a siphon-like odor trap, which can be connected to a wastewater line, is preferably provided in the toilet body and a cleaning device is assigned to the seat ring for toilet arrangements in public areas.

[0028] The siphon, a trap found in all common toilets, is designed so that the flushing action must propel the contents upwards through a narrow passage with high flow resistance before the entire flow, including the fecal matter, can return to the drain. This requires a significant amount of flushing water. The inherent risk of blockage is particularly high in public restrooms, as improperly disposed waste, especially long strands of toilet paper, can quickly clog the siphon and cause the toilet to overflow.

[0029] This is effectively prevented by the flatbed siphon according to the invention, which has a significantly reduced flow resistance. Firstly, in conjunction with the high-pressure nozzles in the seat ring, it is a key element that minimizes the amount of flushing water required. Furthermore, it can prevent blockages, particularly when at least one high-pressure nozzle is provided in the wall of the toilet bowl, preferably opposite the drain, and its flow of water creates the highest flushing pressure in the area of ​​the odor trap. This represents a new fundamental technology, especially for private and, above all, public toilet facilities, as it ensures the permanently trouble-free operation of the odor trap. In addition, the siphon base is automatically cleaned, which offers further advantages in terms of hygiene and aesthetics.

[0030] It should be mentioned at this point that the described design of the flatbed siphon has an independent inventive character and can be used in particular also in toilet facilities that are equipped with conventional flushing systems.

[0031] Instead of the concealed cisterns of known systems, which are difficult to access for repairs, the invention integrates all connection, control, actuation and system components as well as the required quiet air compressor into a support structure, which is preferably installed flush with the wall under plaster and is easily accessible via a removable wall cover.

[0032] The system components include standard commercially available elements such as high-pressure valves for light, normal, and heavy flushing, which determine the flushing time, as well as suitable media diverters. The resulting range of options also allows for the optimization of water consumption, taking into account the specific flushing situation.

[0033] When using the multifunctional toilet seat ring in a public restroom, it is a hygienic requirement that the multifunctional seat ring be automatically washed and dried on both sides. For this purpose, a cleaning station is advantageously provided in the vertical position of the seat ring. This station has a cleaning area that essentially fits the seat ring snugly and features multiple nozzles that can be supplied with water / compressed air and are directed against the surface and underside of the seat ring. The reversal of the seat ring's position from the active horizontal position to the inactive vertical position occurs automatically and automatically after each use of the toilet, triggering a cleaning cycle in the cleaning station.

[0034] The invention enables optimal use in both private and, especially, public settings, as the provided modules allow for a maintenance-free, paperless, and brushless toilet system. This offers a significant aesthetic advantage, given that the toilet brush, ubiquitous today, is often associated with disgust and filth. The environmental benefits, such as reduced drinking water consumption and the prevention of PFAS contamination of the drinking water system, further enhance the invention's advantages. Additional features and benefits of the invention are described below in conjunction with the explanation of the drawings.

[0035] The drawing shows: Fig. 1 a perspective view of an embodiment of the multifunctional toilet seat ring according to the invention in a view from below, Fig. 2 a schematic representation of a toilet body with the toilet seat ring according to Fig. 1 Fig. 3 a perspective view of a further embodiment of the toilet seat ring according to the invention in a view from below, Fig. 4 a schematic representation of a toilet body with the seat ring according to Fig. 3 Fig. 5 a schematic representation of a preferred embodiment of a toilet body according to the invention in conjunction with a multifunctional seat ring, Fig. 6 a schematic representation of a preferred media supply to a toilet seat ring via its pivot axis, Fig. 7 a schematic representation to explain the controlled media supply to the seat ring via its pivot axis in the vertical seat ring position, Fig. 8 one of the Fig. 7 Fig. 9 shows a corresponding representation in the horizontal position of the seat ring, Fig. 9 a schematic partial representation of a toilet arrangement with seat ring according to the invention and associated self-cleaning station, Fig. 10 a toilet arrangement according to the invention in which the toilet seat ring is in the self-cleaning position, and Fig. 11 a schematic representation to explain the cleaning of the toilet ring in the self-cleaning station.

[0036] Fig. 1 Figure 1 shows a multifunctional toilet seat ring 1 which can preferably be attached to a closet body via a pivot axis 2.

[0037] On the underside 3 of the seat ring 1, a projection 4 is provided at the front and a projection 5 at the rear, which serve to receive nozzles 7. These nozzles 7 can be supplied with preferably heated pressurized water and compressed air via channels formed in the seat ring 1, thereby enabling optimal bidet functions and thus making the paperless toilet a reality.

[0038] Fig. 2 Figure 1 shows the toilet seat ring 1 articulated via a pivot axis 2 to a closet body 2 in a horizontal, active position, wherein in this embodiment the projection 4 carrying the nozzles 7 simultaneously serves as a support projection due to the chosen design of the closet body 10.

[0039] It is evident that all known bidet functions can be implemented without any moving or drive-operated components, since the nozzles 7 integrated into the front and optionally rear projections 4 and 5 of the toilet seat can selectively generate controlled jets of warm water and temperature-controlled compressed air, which are essentially horizontally directed and thus always remain within the toilet seat opening. The risk of water splashing out due to improper handling, as is quite possible with known designs, cannot occur here.

[0040] The generation of the water and / or air jets 17, 18 that ensure the bidet functions is independent of the type of method used for the closet flushing, i.e., closet bowl cleaning, which allows its universal applicability even with all conventional toilet arrangements.

[0041] Fig. 3 shows another preferred embodiment of the multifunctional toilet seat ring according to the invention, which in the illustrated form, but also combined with the bidet nozzle variant according to Fig. 2 usable.

[0042] As with the previously described versions of the multifunctional WC ring, this one is constructed in two parts and preferably consists of an aluminum die-cast lower part and a plastic upper part, with both parts together forming the channels for the media water and compressed air, which are supplied separately from both sides of the pivot axis 2 of the seat ring.

[0043] The nozzles 6, arranged in a ring around the opening of the seat ring 1, act as cleaning nozzles directed against the inner wall of the respective toilet body and can be pressurized with water under high pressure. The water pressure present in domestic water pipes is generally sufficient as high pressure.

[0044] The high-pressure nozzles 6 can be designed as pre-assembled individual nozzles, or alternatively, nozzle openings can be formed in the aluminum lower part of the seat ring 1 in the die-casting tool, so that a smooth underside can be achieved and particularly favorable manufacturing costs can be attained.

[0045] By directly connecting the nozzles 6 to the domestic water supply and using suitable control valves, this embodiment of the invention eliminates not only the conventional cistern with its stored, relatively large water reservoir and the associated, calcification-prone functional components, but also ensures particularly effective and comprehensive high-pressure jet cleaning of the toilet bowl. This requires significantly less water than conventional unpressurized flushing systems. This is equivalent to allowing the toilet bowl body to be designed without a rim, i.e., without any horizontal or vertical upper edge, with the now completely rimless design guaranteeing optimal and easy cleaning.

[0046] The schematic representation according to Fig. 4 This illustrates the function and operation of the high-pressure water jets generated by the high-pressure nozzles 6, which can be directed specifically against the inner wall 9 of the toilet bowl. A high-pressure nozzle 6, specifically provided in the base 4, helps to facilitate the removal of the flushing water and the accompanying dirt and fecal matter via a low-resistance, bottom-mounted siphon 16 to the drain 14.

[0047] The representation according Fig. 5 Figure 1 shows the multifunctional seat ring 1 according to the invention in the embodiment with cleaning nozzles 6 and bidet nozzles 7 in conjunction with a closet body 10, which is provided with a particularly advantageous, novel and independent siphon design with reduced flow resistance.

[0048] The flatbed siphon formed by the sloping bottom wall 11, the adjoining rising bottom wall 12 and the vertical wall 13 arranged in the transition area eliminates the disadvantages of conventional siphons, in which the flushing has to transport the contents upwards by 180° through a narrow passage before the total flow with the fecal matter contained therein can return downwards to the wastewater connection.

[0049] At least one high-pressure nozzle 15, provided in the wall of the toilet bowl and located opposite the drain, helps to eliminate the risk of blockages that could cause the toilet to overflow, since such nozzles 15 can generate a media flow 29 that produces the highest flushing pressure in the area of ​​the trap. This also automatically cleans the siphon base.

[0050] This is of particular importance in publicly used toilet facilities, where a permanently trouble-free function of the odor trap is actually indispensable, but could not previously be guaranteed.

[0051] Fig. 6 This serves to explain the media supply to the channels present in the toilet seat ring.

[0052] The pivot axis arrangement of the WC-Witzring 1 comprises a hollow axle 21 fixedly mounted on the respective toilet body and a tubular axle 23 integrated into the toilet seat 1 and rotatably mounted on the hollow axle 21. The interior of the hollow axle 21 is divided centrally by a partition 22, resulting in separate partial cavities 19, 20. In practice, this is achieved, for example, by designing the fixed hollow axle in two parts and screwing it to a solid part in the middle.

[0053] The two partial cavities 19, 20, each of which is connected to channels 31 leading to the respective nozzles in the seat ring 1, can be connected via inlet openings 25, 26 to media connections in fixedly mounted axle carriers 24, depending on the pivot position of the seat ring 1.

[0054] Fig. 7 shows the seat ring 1 in a vertical position in which all nozzles in the seat ring are separated from any media supply.

[0055] Each of the two hollow shaft sub-spaces 19, 20 has a valve-forming opening 28 located opposite a wall of the pipe shaft 23 integrated in the seat ring in this position and is thus tightly sealed. Media flow from the sub-space 19 into the channel 31 is therefore reliably prevented.

[0056] Fig. 8 shows the arrangement according Fig. 7 In the horizontal position of the seat ring 1, the opening 28 is aligned with the channel 31, allowing media flow from a given source through the partial cavity 19 into the channel 31 and thus to the respective nozzles. The valve-forming interaction of opening 28 and pipe axis 23 occurs in the same manner for the two separate partial cavities.

[0057] In conjunction with upstream, controllable media diverters, the high-pressure and bidet nozzles can thus be supplied with the required media in the form of high-pressure water, moderate high-pressure water as spray water for bidet nozzles, and compressed air for rapid drying, each possibly heated, in the horizontal position of the seat ring 1 during the respective desired periods.

[0058] Fig. 9 shows the multifunctional seat ring 1, which is articulated to a closet body 10 in its horizontal active position, in conjunction with a cleaning station provided on the back of it.

[0059] This cleaning station, in which the seat ring 1 is essentially positively locked into its vertical, passive position, has a cleaning area 30 equipped with spray nozzles 31 for washing and drying the upper surface of the seat ring. Optionally, additional spray nozzles can be mounted on the outer surfaces surrounding the seat for cleaning the underside of the seat and the bidet attachments. The spray nozzles 31 are sequentially supplied with high-pressure water for washing and compressed air for drying via a common annular channel at the rear. An upstream media diverter with two valve functions for water and air allows for automation of this process.

[0060] Fig. 10 Figure 1 shows the toilet seat ring 1 in a schematically represented toilet system in its vertical passive resting position, in which it is enclosed by the washing system 30 and is thus in a ready position for the next use process, before which it is swung back into the horizontal active position.

[0061] It is schematically indicated in Fig. 10 also a hand washing and drying unit 34 assigned to the toilet unit, whereby the compressed air available due to the air compressor present in the system can be used to dry the hands in seconds.

[0062] Fig. 11 shows a schematic side view of the cleaning station after Fig. 10 with the seat ring 1, which is in a vertical position and pivotable about the axis 2, and whose seat surface can be cleaned by means of high-pressure water and compressed air via an annular channel 35 and spray nozzles 31 supplied by it. The draining water is directed into the toilet bowl via a drainage channel 32.

[0063] The contact surface between the human body and the toilet seat ring places the highest demands on credible and perceptible hygiene. These high demands are ensured by the inevitable pivoting of the toilet seat ring 1 into its passive vertical position after each use, resulting in perfect full-surface cleaning in both the cleaning and resting positions.

[0064] Especially in public restrooms, it is crucial that users find and can easily recognize perfectly hygienic conditions. For example, the cleaning function can be reactivated upon entering the facility and made visible and audible, for instance, through light signals and a small amount of visible water mist around the seat ring in the vertical cleaning position. Moderate sounds from the compressed air drying of the seat ring further indicate to the user that cleaning is currently underway, which can also be indicated by pulsating light or acoustic signals.

[0065] The multifunctional toilet seat ring with its modularly expandable extension stages, in conjunction with suitable toilet bodies, in particular toilet bodies equipped with the flatbed siphon according to the invention, makes it possible to guarantee an unusual and previously unattained level of cleanliness, aesthetics, hygiene and drinking water-related sustainability, especially in toilet facilities intended for public use, and thus to create rimless, maintenance-free, paper-free and, above all, brush-free toilet facilities.
