Description

The present invention relates to sanitary articles, in particular toilets and urinals, with rimless bowls which are easy to clean and a method of cleaning.

Traditional toilet bowls frequently have a rim on the top of the bowl, on the underside of which flushing water escapes. Regular cleaning of toilets of this kind frequently involves a toilet cage containing a rim block being fastened to the rim of the toilet bowl in such a manner that said rim block is submerged in water during each flushing action, wherein cleaning and fragrance agents are released and the rim block gradually dissolves. Regular cleaning can also frequently take place via the cistern. Insofar as they are accessible, cisterns can have cleaning agent blocks added to them. The cleaning agents gradually dissolve in the cistern over a plurality of flushing cycles and thereby produce flushing water containing cleaning and/or fragrance agents.

However, the disadvantage of toilets with a rim is that impurities from the toilet get in/on the rim and in the rear area of the toilet under the porcelain wall portion acting as a deflector plate and these places cannot be cleaned or can only be cleaned unsatisfactorily with a small brush.

Furthermore, toilets and urinals are known in the art which have neither an accessible cistern nor a toilet bowl rim on the underside of which flushing water emerges. In these kinds of rimless bowls, flushing involves the bowl being wetted by water with a defined flow profile. The flushing water in this case is generally conducted in such a manner that the water from the flushing water supply line is deflected against the rear side of a porcelain wall portion which extends at right angles to the longitudinal axis of the supply line. The wall portion is part of the toilet bowl and, in conjunction with further conducting elements which form open flow channels, causes the flushing water to emerge into the bowl in a defined manner on the sides and on the underside of the wall portion through a plurality of openings or gaps. The wall, the conducting elements and the bowl are configured in such a manner in this case that through the deflection on the wall portion, the shape of the conducting elements and the shape of the inner wall of the bowl, the inner surface of the bowl which is to be cleaned is completely wetted. The flushing water is then conducted through the outlet of the drainage pipe located in the bowl.

Rimless toilets of this kind are sold by Keramag under the brand name "Renova Nr. 1", "4U" or "iCon", by Toto under the brand name "Tornado Flush" or by Mansfield under the brand name "Cascade", for example.

Since these toilets have no rim, the contamination on/in the rim known from the state of the art does not occur. Instead, the rimless toilet bowl is free from undercuts or the like, except for the small area of the flushing water outlet, which means that contamination - except for the outlet region for the flushing water -is easily accessible and can be simply removed using a traditional toilet brush.

In the case of toilets and urinals of this kind with rimless bowls, however, contamination occurs, for example due to lime and/or urine scale and faeces, algae or fungus in the region of the outlet openings and gaps which are very hard or impossible to remove.

The formation of lime and/or urine scale and faeces, algae or fungus alters the flow profiles, i.e. there is a risk of the entire bowl no longer being submerged in flushing water. In the worst scenario, the openings and gaps are even clogged up with lime and/or urine scale and faeces, algae or fungus.

Frequently only partial cleaning in the area of the openings and gaps for the outlet of the flushing water is only possible by hand during one-off cleaning which is regarded as extremely unhygienic by the consumer, because it is necessary to bend over in the direction of the inner side of the bowl and then use a small brush to scrub the frequently inaccessible openings and gaps within reach of the brush.

Within the institutional hygiene sector involving hospitals, kindergartens or old people’s homes, this kind of cleaning by hand which, moreover, does not produce the desired result, is completely out of the question.

If, in a similar way to the toilet cage, a cleaning agent were to be fastened in a container or by adhesive bonding in the defined flow profile, for example using the means described in WO 2009/106220, the entire flow profile would be affected and proper rinsing of the bowl would therefore be prevented. A dosing unit is known from DE 198 51 754 C2 for the release of a flushing water additive on a flushing water distributor provided for fitting in a bowl rim of toilets or urinals configured as a rim, having a housing provided with the connection fitting for the water supply, wherein the housing has a tank for receiving a flushing water additive. Dosing devices of this kind are provided for fastening to a toilet with a rim and may be fitted subsequently in such a manner that the housing is placed beneath the rim adjacent to the wall of the bowl.

During use, however, considerable contamination occurs and urine scale forms between the bowl wall and the outer wall of the dosing device. This contamination is very difficult to remove. The fact that the device is fastened to the rim also makes the cleaning of said rim more difficult. A cleaning system for toilets/urinals is known from DE 203 12 102 Ul, in which one or a plurality of refillable containers are integrated in the porcelain of the toilet/urinal at the side next to the flushing water pipe and are connected to the flushing water pipe in such a manner that mixing of the flushing water and the container contents is possible.

The disadvantage of these refillable containers is that they cannot be cleaned or only with some difficulty. This means that the container gradually becomes overgrown with a bacterial lawn, particularly when the container is refilled with cleaning agents which promote the growth of bacteria. A toilet bowl is known from GB 826 603 which has a rim, wherein in the wall of the bowl alongside the water inlet a container is formed, the outlet openings of which are connected to the bowl. The container is used to hold cleaning agents. In this toilet too, the outlet openings gradually become clogged with urine scale and can only be cleaned with great difficulty. DE 10 2005 029 609 A1 discloses a flushing water guide for a toilet bowl with a rim which comprises a housing with a connection fitting for connecting to the connection pipe and openings extending at the side and on the underside for the outlet of flushing water. The housing is fitted in the bowl rim which has a recess in the rear region and the connection fitting is fixedly connected to the connection pipe. Above the housing, a delivery device is provided for delivering active substances as an additive to the flushing water, which delivery device is replaceable.

The problem that also affects this flushing water guide is that splashes pass through the downwardly oriented openings into the housing, the housing gradually clogs up and cannot be cleaned. EP 2 341 196 B1 discloses a mixing arrangement formed integrally within the sanitary bowl which comprises a supply line and a plurality of drainage lines extending between the mixing chamber and the bowl. A holder for a cleaning agent is located in the mixing arrangement. The disadvantage of this mixing arrangement is that the openings of the outlet lines oriented in the direction of the bowl gradually clog up with urine scale or contaminants due to splashes from the toilet bowl and cannot be cleaned.

The problem addressed by the present invention involves improving the cleaning of rimless sanitary articles such as toilets and urinals in the region of the openings or gaps projecting into the bowl for the through-passage of the flushing water and preventing contamination in this area.

This problem is solved in that with the toilets and urinals known hitherto with a connection pipe for the flushing water supply, a bowl and a wall portion with openings, wherein the openings in the wall portion are used for the through-passage of the flushing water into the bowl, the wall portion with the openings is a wall element with openings that can be removed upwards from the bowl and the wall element can be connected in a form-fitting manner to the bowl on both sides.

The fact that the wall element with the openings which are easily contaminated by the formation of urine scale and gradually “overgrown”, destroying the entire flow profile, is not an area of the toilet bowl according to the invention, but can be completely removed from the use position for cleaning purposes as a single part, means that simple cleaning, particularly of the openings of the wall element, is possible, wherein the wall element is then fastened back into the bowl in the use position or can be replaced by a new element.

In a preferred embodiment the wall element can be exclusively fastened to the bowl by both its sides, which means that it can easily be removed by the consumer during routine toilet cleaning, cleaned and refitted again, something that is not possible with the device known from DE 10 2005 029 609 Al, in which the container is attached to the pipe in the rear toilet area.

The wall element according to the invention is removable from the bowl as a part or piece. The wall element is preferably of one-part design and, in a further variant, particularly of one-piece design.

The surface of the wall element pointing in the direction of the inside of the toilet bowl is preferably planar. The wall element is preferably configured in the shape of a slightly curved plate corresponding to the curvature of the bowl which has openings for the through-passage of water and means for fastening to the sides of the bowl.

In the use position, i.e. when the wall element is introduced into the bowl and the side of the wall element which is oriented into the centre of the bowl forms an encircling, more or less completely smooth surface with the inner side of the bowl, the transition between the lateral edges of the wall element and the edges of the upper area of the inner surface of the toilet bowl laterally adjacent thereto is virtually continuous. In other words, the shape of the inner side of the toilet bowl with the wall element corresponds to the shape of the inner side of a traditional toilet, except that the wall element is designed as a removable part which, as such, can be removed from the use position.

The toilet according to the invention is therefore as easy to clean over the entire bowl area as a traditional toilet. However, the removable wall element opens up yet another cleaning possibility in the region of the openings which is not known in traditional toilets. The region of the incoming flow in which, as will be explained later, cleaning agents can also be positioned, can also easily be cleaned after the wall element has been removed and any bacterial lawn can be removed.

The removal of the wall element (deflecting wall) alongside openings is far simpler and more hygienic than the practice followed hitherto - if at all - in the case of toilets with or without a rim with contaminated openings integrated into the ceramic, namely that of kneeling down and using a small brush to get into the contaminated openings and clean them, insofar as the brush actually reaches into the opening. “Upwardly removable” not only means a completely perpendicular removal, but also a removal obliquely from above (e.g. at an angle of 70° to 90° in respect of the horizontal).

The openings in the wall element are used for the direct through-passage of the flushing water into the bowl or the rim and not for filling a further vessel.

In the case of the wall element removed from the bowl, all outer surfaces are accessible for cleaning.

There are different variants for the form-fitting fastening of the removable wall element in the bowl.

Preferably, the right and left sides of the wall element can each be connected to the bowl via a groove connection. The groove connection may, for example, be a groove-spring connection, wherein the groove may be provided on the bowl and the spring on the side of the wall element or vice versa.

In a preferred variant, the wall element has two formed retaining lips on the side, each of which can be fastened into a corresponding groove in the bowl. The wall element in this case is pushed from above into the groove in the bowl. When the wall element is removed for cleaning purposes, the groove is then also accessible for cleaning purposes.

Likewise, a dovetail joint between the wall element and the bowl is possible.

In a further variant viewed from above, the two side walls of the wall element run obliquely in the direction of the inner side of the bowl, so that the wall element is pressed by the flushing flow against the corresponding oblique surface on the bowl.

In general, the groove connection between the wall element and the bowl runs in a vertical direction; in a further variant, the groove connection between the wall element and the bowl runs obliquely upwards, in order to counteract upward pressure on the wall element by the flushing flow.

In the case of the rimless toilet, it is likewise possible for an opening in the bowl to be provided with means for a form-fitting fastening, wherein the opening is located at the place where the wall portion is customarily located and the peripheral piece upwardly joined thereto. An L-shaped wall element with a horizontal plate can be pushed into this opening from above in such a manner that to the right and left of the wall portion is attached the inner side of the bowl and to the right and left of the top of the horizontal plate is attached the top of the rim attached to the top of the plate on the right and left.

If the wall element is of L-shaped design, the long leg of the L in this case corresponds to the previously described vertically running wall element, to the upper edge of which is attached a plate running at right angles (short leg of the L), which plate for its part serves to cover the opening in the periphery of the rimless toilet.

The width of the wall element depends on the diameter of the connection pipe. The width should at least correspond to the width of the connection pipe. The wall element is preferably between 3 and 30 cm, preferably between 8 and 25 cm and particularly preferably between 15 and 20 cm wide.

The fact that the wall element can be completely removed from the toilet and reinserted means that a holder can be fastened to the side of the wall element not pointing in the direction of the inner side of the bowl, which holder can be used to store cleaning agents in block form, gel form or liquid form.

Since the wall element is removable from the use position, the rear area of the wall element with the holder is also accessible, i.e. in the context of the removal of the wall element for cleaning purposes, for example, a new cleaning agent can also be inserted in the holder at the same time.

In a further variant, the wall element is not of L-shaped but U-shaped design, the one leg forms the previously described deflecting plate, the base of the U corresponds to the previously described leg of the L and the other leg of the U is used to overlap the outside edge of the toilet and acts as an abutment. In this variant, which is suitable for free-standing toilets and urinals, the form-fitting connection to the bowl is achieved through the U-profile fitted onto the bowl, so that depending on the configuration even the previously described lateral groove connections can be dispensed with.

It is likewise possible for the further leg of the U to be configured in the shape of two individual legs or pins which engage with corresponding vertical bores in the rim. This variant is particularly suitable for wall-mounted toilets.

The L- or U-shaped wall element may also take the shape of an expendable product, preferably with an integrated cleaning agent, which can then be refilled or replaced during cleaning as with a customary toilet cage.

The cleaning agent can also be introduced without additional fastening means straight into the connection pipe for the water supply, wherein a special device for dosing into the pipe (pipe-in-pipe system) can also be provided.

In addition, a special dosing device such as a pump with a battery can be introduced into the pipe. A cleaning agent of this kind located in the region of the incoming flow of flushing water in the flow direction upstream of the bowl and the outlet directions and also, in general, upstream of the conducting elements does not have a detrimental effect on the flow profile in the bowl. It partially dissolves before each flushing action in the water found in the incoming flow and therefore provides cleaning and/or fragrance agents in the flushing water, as is also known, for example, in the case of cleaning products which are added to toilet cisterns.

Alternatively, the cleaning agent may also be adhered to the side of the wall element oriented in the direction of the incoming flow of flushing water, wherein adhesive viscous cleaning agents which are known either from WO99/66017, EPl 325 103 Bl, EP 1 318 191 B1 or DE 10 2004 056 554 Al, for example, can be used. Toilet cleaning agents in block form can also be adhered to the deflector wall side of the wall element by means of special adhesive pastes which are known from WO 2009106220 Al.

In a further variant of the invention, at least one partial area of the wall element is transparent or has an inspection window, so that the consumer is able to check whether the cleaning agent needs topping up.

It goes without saying that the wall element on the side oriented in the direction of the connection pipe comprises guide surfaces and/or openings on the side and/or bottom, which guide and distribute the water in the desired area of the bowl.

In this way, the present invention not only makes it possible for sanitary articles to be easily cleaned in the region of the openings, but for the first time it also allows easy regular cleaning of rimless toilets, without the flow profile in the bowl being detrimentally affected.

The wall element according to the invention may be made of different materials such as, for example, plastic, high-grade steel, glass or also ceramics.

Likewise, it is possible for the wall element to be produced from plastic and then blended with ceramics or other materials.

Plastic, possibly blended with ceramics, is preferably used, as a separate plastics part is simple to produce, easy to clean and tolerances can also be observed far more effectively during production than is the case with ceramics parts.

In a further variant, some or all openings can be designed with nozzles, in order to allow a better and more selective orientation of the flushing water flow in the toilet. These nozzles may be rigid or also extendable in the direction of the bowl during the flushing operation on account of the water pressure. As a general rule, depending on the shape and orientation of the nozzles, they can also facilitate a different distribution and orientation of the individual flushing water currents in the toilet. Consequently, the removable wall element which has openings with nozzles also allows the flow profile to be improved right in the area of great contamination or the places which receive less wetting.

Unlike the additive containers known from the state of the art which are fastened in the bowl, in the case of the wall element according to the invention, a container rear wall which can gather further dirt and urine scale between it and the inner side of the bowl is dispensed with. The wall element according to the invention preferably has no surface directly adjacent to the inner wall of the bowl or the inner rim of the toilet; instead, it is only held at the sides or in an area of the toilet remote from the inside of the bowl. To this extent, contaminants are also unable to accumulate between two walls lying adjacent to one another in or proximate to the toilet bowl.

Moreover, the wall element according to the invention cannot be additionally fastened to a traditional bowl either, but the wall element can be fastened to a special bowl without a wall portion and then produces a conventionally shaped toilet, when fitted into the bowl without a wall portion, in which, however, contrary to the state of the art, the wall portion can be removed. The wall element according to the invention forms a removable part of the toilet or urinal and is not an additional storage container. A further advantage of the present invention is also that the sanitary article according to the invention can also be used in the institutional field, as it allows easy, hygienic regular cleaning.

The invention and also further advantageous embodiments and developments of the same are described in greater detail and explained below with the help of the examples depicted in the drawings.

Figure 1 shows a toilet 11 with a toilet bowl 12, an upwardly folded toilet seat 13 and a likewise folded-up lid 14. The lid 14 and seat 13 are pivotably fastened to the bowl 12 by corresponding means 15.

The bowl 12 has on its upwardly oriented side a planar rim 16 on which the toilet seat 13 rests in the closed position.

The inwardly oriented wall 18 of the bowl 12 is slightly curved and, moreover, largely smooth (Figure 4). Individual conducting elements 19 are provided on the inner bowl wall 18 which are used to conduct the water entering the inner side of the bowl through openings 21 from the rear region of the bowl 12, namely the connection pipe 23, with a defined flow profile in the manner of open flow channels along the inner wall 18 of the bowl. Main flow directions 30 are shown using dotted lines in Figures 1 and 6. The water flows off via the drainage pipe 24 in the lower bowl region.

In the case of the toilet 11, a wall element 20 with openings 21 is provided in the rear area of the toilet bowl 12, i.e. close to the water connection pipe 23, rather than the traditional wall portion acting as a deflecting wall, which wall element 20 can be removed from the bowl 12. During the flushing action, the water flowing from the connection pipe 23 in the direction of the bowl 12 is deflected “from behind”, i.e. in the direction of the arrow A in Figure 4, against the wall element 20 which is fastened to the ceramic bowl 12. The inflowing water is distributed following the deflection on the wall element 20 in the flow direction, particularly to the right, left and downwards and then it enters the bowl through the openings 21 located at the sides and in the lower area of the wall element 20.

The wall element 20 which is represented schematically in a first embodiment in Figure 5 has retaining lips 26 on both the right and left sides 25 of the wall element 20 which are used for fastening in corresponding grooves 27 in the bowl 12.

The lateral transition between the wall element 20 and the bowl 12 should be virtually continuous, i.e. the visible side 34 of the wall element 20 should merge virtually continuously into the inner wall 18 of the bowl, in order to avoid contaminants in the transition area, but also to convey the overall impression of a uniformly encircling “round” bowl rim.

For fastening purposes, the wall element 20 in this embodiment is simply pushed from above into the grooves 27 in the bowl 12. At the lower end, the grooves 27 have openings ending in the pipe space 23, so that any contaminants in the grooves 27 can also be flushed out. Since the grooves 27 are located outside the inner side of the bowl and the openings 21, these cannot be contaminated with urine scale in the same way as the openings 21.

The wall element 20 must of course be sufficiently rigid to be able to act as a deflecting wall for the inflowing flushing water.

Likewise, the fastening of the wall element 20 to the bowl 12 must of course resist the water pressure.

In the detail view of the wall element 20 in Figure 5, openings 21 are depicted in the lower area of the wall element 20. Instead of openings 21, there may also be a gap between the lower edge 31 and the bowl 12, through which the through- passage of water is made possible.

In addition, lateral openings 21, as shown in Figure 5a, can be provided or both lateral openings and also downward openings. In addition, the wall element 20 on the side oriented in the direction of the connection pipe 23 may still exhibit guide surfaces, in order to guide the flow of water according to the requirements of the bowl 12.

In order to clean the easily contaminating openings 21 in the wall element 20 (and also the bowl 12), the wall element 20 is removed from (pulled out of) the bowl 12 and cleaned in a washbasin, for example, using water and possibly a brush and urine scale remover or similar or cleaned in an automatic washing unit provided for this purpose (bedpan washer available from Hagmann or Topol).

Following removal of the wall element 20, the bowl 12 can also easily be cleaned with a brush, as all surfaces which could possibly be contaminated by splashes from the toilet space can be directly cleaned by simply going over them with the brush from above, without bending over or using special brushes for inaccessible places.

The fact that the openings 21 are easy to clean due to the possibility of removing the wall element 20 means that it is no longer the case that the openings 21, as in the state of the art, gradually become clogged up with urine scale and that the flow profile is adversely affected until the bowl 12 is no longer completely wetted by flushing water.

Compared with traditional toilets, in the case of the toilet 11 according to the invention, the wall portion 20 with the openings 21, against which the flushing water from the connection pipe 23 is deflected from behind, is not part of the ceramic bowl but a separate removable part.

Figure 7 shows schematically how a toilet cleaning and/or fragrance block 28 for regular cleaning can be fastened to the side of the wall element 20 oriented in the direction of the connection pipe 23. For this purpose, a cage-like container 29 can be formed on or attached to the side of the wall element 20 oriented in the direction of the connection pipe 23, in which container a cleaning agent 28 which gradually dissolves during each flushing action can be stored. The wall element 20 may comprise a horizontal plate 50 or have a U-shaped design (not shown in Figure 7). A cleaning agent 28 of this kind in a four-person household is generally used up after 1 to 2 weeks and can then be replaced again by removing or pivoting out the wall element 20 and filling the container 29.

It goes without saying that means 29 of fastening the cleaning agent 28 can also be formed in a different way or attached to the wall element 20 in a different manner.

Instead of the additional fastening means 29 for the rim blocks 28, the rim blocks 28 may, however, also be adhesively bonded directly to the rear side of the wall element 20, for example using the means known from WO 2009/106220 Al. It is likewise possible, instead of a solid rim block 28, to use a highly viscous adhesively bonding cleaning agent and to bond this adhesively directly or indirectly to the wall element 20.

In order to further improve the flow direction of the flushing water in the bowl 12, the openings 21 can also take the form of nozzles which also make different directions possible for the emerging flow, as is shown schematically in Figures 8a, b.

Figure 8c still shows a nozzle schematically which is moved out by water pressure (in the direction of the arrow) and flushes radially perpendicularly to the water inlet and returns to the starting position again at the end of the flushing process.

Examples of form-fitting connections between the wall element 20 and the bowl 12 or else the rim 40 are depicted in Figure 9. According to Figure 9a, the wall element 20 depicted as a plan view from above of the bowl 12 on the right and left sides 25 has in each case a spring (lug) 26 which can be pushed from above into a corresponding groove 27 in the bowl 12. The rear side 42 of the wall element 20 is oriented in the direction of the connection pipe 23 (cf. also Figure 3).

Figure 9b shows the bowl 12 with the connection pipe 23 connected fixedly and, in particular, integrally thereto and the groove 27 for insertion of the wall element from Figure 9a in plan view. The upwardly oriented side 16 of the bowl 12 is planar and ring-shaped. In the rear area of the bowl 12, the connection pipe 23 represented by dotted lines is located below the upwardly oriented side 16'.

Figure 9c shows a groove connection between the wall element 20 and the bowl 12, in which on either side 25 of the wall element 20 a groove 47 is provided and on the corresponding side of the bowl 12 a spring or projecting lug 46 is provided.

Figure 9d shows a trapezoidal wall element 20 in which both sides 48 of the wall element 20 run towards one another in the direction of the inner side of the bowl. In the direction of the inner side of the bowl, the wall element 20 has a lug 26" which is used to engage behind the edge 27" on the bowl 12. The pressure of the water from the connection pipe 23 striking the rear side 42 of the wall element 20 causes the wall element 20 to be pressed by its oblique sides 48 against the sloping sides 49 on the bowl 12. A variant with a dovetail joint is depicted in Figure 9e.

Figure 10 shows a toilet 11 with a rim 40 (not according to the invention) and a removable wall element 20 with a horizontal plate 50 in cross section. Unlike the depiction in Fig. 4, in the case of a toilet 11 with a rim 40, the rim 40 has a U-shaped design, as depicted in Figure 11 for the front area of the toilet 11. In the case of a toilet 11 with a rim 40, it is possible for the wall element 20 along with the horizontal plate 50 attached to it at right angles and fixedly connected to the wall element 20 to be removably configured, so that the wall element 20 with the horizontal plate 50 preferably integrally connected thereto can be removed upwardly as one part and cleaned. Following removal of the wall element 20, the area of the connection pipe 23 can then also be cleaned. If the wall element 20 is inserted with the plate 50, the top of the plate 50 along with the top 16 of the rim 40 attached at the sides produces a planar surface.

The plan view of a toilet 11 with a rim 40 (not according to the invention) and inserted wall element 20 with a horizontal plate 50 is depicted in Figure 11 and a perspective view of the rear area of the toilet 11 is depicted in Figure 12. Figure 13 shows the wall element 20 with the horizontal plate 50 in cross section.

Figure 14 shows schematically the variant of a U-shaped wall element 20 with an abutment 51. In this variant, the wall element 20 bears at least partially with the inner side 53, 54, 55 against the bowl 12. A further variant of a U-shaped wall element 20 is depicted in Figure 15. Unlike the variant in Figure 14, the “2“** leg” comprises two individual legs 52 or pins which engage with two corresponding substantially vertical bores 60 in the bowl 12, which are represented by dotted lines in Figure 12. A further variant, namely with a U-shaped wall element 20, is shown in Figure 10a. The wall element 20 in this variant comprises, apart from the horizontal plate 50, also a plate 51 acting as an abutment which is attached to the horizontal plate 50 at right angles in a downwardly running manner, which overlaps the toilet rim.

Since this U-shaped wall element 20 encloses the upper edge of the bowl 12 through the bearing on three surfaces and a form-fitting connection to the bowl 12 is therefore achieved, additional fastening by the lateral groove 27 is not necessarily required in this variant.
