Description

The invention relates to a toilet bowl, in particular of ceramic, with a bowl edge and a downwardly open distribution apron, which is arranged in front of an inflow opening and forms a baffle plate. The edge of the bowl has a circumferential projection, which forms a skirtless water supply. The water guide is fluidly connected to the distributor skirt.

Such a toilet bowl is for example off GB 2 431 937 known.

The invention further relates to a toilet with such a toilet bowl.

For toilet bowls, the flushing process has two functions. On the one hand, the dishwashing water cleans the bowl wall of faeces. On the other hand, the water in the bottom of the toilet is transported to the sewage system. For a complete flushing of the bowl inner surface, the rinse water is distributed from the inflow on the circumference of the bowl, so that the rinse water can flow into the sump at the bowl inner wall. For this purpose, the aforementioned known toilet bowl on a distribution apron, which is arranged in front of the inflow opening of the bowl edge. The distribution apron forms a baffle plate which distributes the rinse water flowing in from the inflow opening in both directions on the circumference of the bowl. The squirting out of Rinse water should be avoided by a projection that extends along the edge of the bowl and forms a skirtless water supply. This does not succeed in the known bowl, so it sometimes comes to unwanted Spülwasserspritzern.

The invention has for its object to improve the known toilet bowl to the effect that the security against splashing out of the rinse water is increased, the good accessibility of the water supply to clean the bowl should be maintained. The invention is also based on the object of specifying a toilet with such a toilet bowl.

According to the invention the object is achieved by a toilet bowl with the features of claim 1 and overlooking the toilet by the subject of claim 10.

The invention is based on the idea of specifying a toilet bowl, in particular made of ceramic, with a bowl rim and a distributor apron open at the bottom. The distribution apron is arranged in front of an inflow opening of the bowl edge and forms a baffle plate. The bowl edge has a circumferential, in particular a completely encircling, projection which forms a skirtless water supply. The water guide is fluidly connected to the distributor skirt. The toilet bowl according to the invention is characterized in that the projection has a horizontal first wall, which merges into the baffle plate of the distribution apron. The bowl edge has a downwardly extending second wall. The first and second walls define a laterally and downwardly open hollow channel of the water supply.

The invention has several advantages.

The safety against splashing out of the rinse water is increased by the invention, because the horizontal first wall of the projection merges into the baffle plate of the distribution apron. As a result, a closed fluid connection between the skirtless water guide and the distributor skirt is formed, so that the rinse water can not splash out of the toilet bowl in the region of the transition between the water guide and the distributor skirt. Moreover, the rinse water in the water supply, ie in the flow direction after the distribution apron, securely held back in the toilet bowl, as the first and second wall defining a hollow channel, which, in particular by the first horizontal wall, allows an improved water flow, which securely retains the guided along the edge of the bowl rinse water in the bowl. The hollow channel of the water guide formed between the first and second wall is open laterally and downwardly, whereby a simple cleaning of the water supply is possible. This preserves the benefits of the seamless water supply and at the same time increases the safety against splashing out of the rinse water.

Surprisingly, it has been found that the inventive inwardly open construction of the bowl rim is sufficiently stable to safely absorb the forces introduced when using the toilet bowl over the bowl edge. This is also possible even if the bowl rim has a completely circumferential projection formed by a horizontal first wall which merges into the baffle plate of the distribution apron.

In addition, the inventive design of the toilet bowl brings a significant aesthetic effect with it. In comparison to the known toilet bowl mentioned above, the toilet bowl according to the invention causes a light and filigree overall impression, since the known massive projection is replaced by the first and second wall. In addition, the transition of the horizontal first wall into the baffle plate of the distribution apron forms an unusual embodiment of the toilet bowl, which attracts the eye of the beholder.

In another preferred embodiment, the downwardly extending wall is inclined inwardly. Thus, on the one hand, an elegant shape of the toilet bowl is achieved because the second wall limits the outer periphery of the bowl edge and the inwardly inclined arrangement of the second wall determines the outer contour of the toilet bowl. On the other hand, the inclined arrangement leads to a good transfer of forces from the bowl edge to the lower portion of the toilet bowl.

The water flow can be improved, for example, by the fact that the edge of the bowl has a circumferential shoulder which delimits the hollow channel downwards. The circumferential heel also has an aesthetic effect, as the bowl edge is set off from the bottom of the toilet bowl. The horizontal one first wall is further inward than in front of the circumferential paragraph, so that the hollow channel is open at the bottom and on the one hand the splash protection effect up and on the other hand the good water drain down is possible.

The first and second walls may have the same wall thickness. This simplifies the production of the toilet bowl. Here too, an additional aesthetic effect comes into play, since the limited wall thickness of the two walls enhances the filigree, light overall impression of the toilet bowl.

In a particularly preferred embodiment, the horizontal first wall continuously merges into the distribution apron. This has the technical advantage that the water supply is increased inwards, ie in the plane of the baffle wall along the bowl circumference, so that the security against spewing rinse water is increased. In addition, there is the visual effect that the continuous transition between the first wall and the distribution apron gives a harmonious overall impression of the toilet bowl.

There is creative freedom for the transition between the first wall and the distribution apron. For example, a transitional edge between the horizontal first wall and the distribution apron may be formed, so that the toilet bowl acts more angular overall.

Preferably, the distributor skirt extends along a partial circumference of the bowl rim that is 25% to 35% of the total circumference. This creates sufficient security against spewing rinse water.

In a particularly preferred embodiment of the invention, a lower edge of the distributor skirt is arranged at the same height or higher than an inner edge of the toilet bowl in the region of the inflow opening. This arrangement of the lower edge of the flushing performance of the toilet bowl is improved. It is particularly advantageous if the lower edge of the distributor skirt is arranged higher than an inner edge of the toilet bowl in the region of the inflow opening. The improvement in the flushing performance is reflected in the fact that a larger partial flow from the inflow opening flows directly into the toilet keys. This will be the area of the toilet bowl that is directly below the distribution apron itself located, cleaned very well. The statement "in the region of the inflow opening" means that the distributor apron at least partially, in particular completely, overlaps the inflow opening. Based on the geometry of the toilet bowl, the lower edge of the distribution apron is arranged in the region of the central longitudinal axis of the toilet bowl at the same height or higher than the inner edge of the toilet bowl. The central longitudinal axis of the toilet bowl is the axis that cuts the toilet bowl longitudinally in the middle. The lower edge of the distribution apron is arranged symmetrically to the central longitudinal axis.

In other words, the lowest point of the lower edge of the distributor skirt is arranged at the same height or higher than the inner edge of the toilet bowl.

The above-described height of the lower edge is disclosed and claimed both in connection with the horizontal first wall passing continuously into the distributor skirt and in connection with the transitional edge between the horizontal first wall and the distributor skirt and independently of the transition described above.

According to the toilet Fig. 1 It is a standing toilet with one foot to be mounted on a floor. The invention is also applicable to other types of toilets, for example, for a hanging toilet, which has no foot, but is fixed in a conventional manner to a wall. The same applies to all embodiments described in this application. The invention generally relates to so-called deep-rinse, in which the bottom of the bowl is connected to a siphon to prevent odor ( Fig. 4 ).

The detail features described below are in accordance with both embodiments Figures 1-4 such as Figures 5-8 realized and will be described and disclosed in connection with both embodiments. The differences between the embodiments exist in the transition between the horizontal wall 14 and the distribution apron 11, which will be discussed separately.

As shown in all figures, the toilet bowl has a bowl rim 10 which defines an upper opening of the bowl. The bowl edge 10 is in a mounting surface 18, which serves to attach the toilet seat and the toilet lid. For this purpose, corresponding fastening openings are provided. Optionally, adjoining the attachment surface 18 is a mounting region 19, to which a cistern can be attached. The mounting area 19 has a water connection for the supply of the rinse water. Wall-hung toilets are adjusted accordingly.

As in FIGS. 4 and 8th to see, the toilet bowl has a central inflow opening 12 which is centrally located in the region of the bowl edge 10. The drain opening 20 is formed in a conventional manner in the bottom of the toilet and includes a siphon. Between the drain opening 20 and the inflow opening 12, the flushing area 21 of the bowl extends. The in the Figures 1-8 shown illustration of the purge region 21 is to be understood as an example. There are creative freedom to form this area differently, in particular according to aesthetic aspects.

As in the FIGS. 4 and 8th clearly visible, the bowl edge 10 has a downwardly open distribution apron 11. The distribution apron 11 extends inwardly from the upper edge of the bowl rim 10 into the toilet bowl. The distribution apron 11 is arranged in front of the central inflow opening 12 and forms a baffle plate. This has the function of diverting the flushing water flowing out of the inflow opening 12 on both sides in the circumferential direction of the bowl, so that it is possible to flush around the entire flushing area 21 along the bowl rim 10 as far as possible. The distribution apron 11 is open at the bottom, so that a gap 22 is formed between the baffle plate and an inner edge 23 of the bowl. When rinsing flows through the gap 22, a portion of the rinse water in the toilet bowl, so that located below the distribution apron 11 excreta are washed off.

The inner edge 23 in the region of the distribution apron forms the end edge of a flow space 24 a, which forms part of the inflow opening 12. As in the FIGS. 4 and 8th can be seen, the lower edge 25 of the distribution apron 11 is formed deeper than the inner edge 23, so that the distribution apron 11 completely overlaps the inflow opening 12. This ensures that the flushing water flowing in from the inflow opening 12 is reliably deflected downwards in the region of the distributor skirt 11.

Surprisingly, it has been found that an alternative arrangement of the lower edge of the distribution apron improves the rinsing performance. As in the embodiment according to Fig. 9 represented, in the variant, the lower edge 25 of the distributor skirt is higher than the inner edge 23 is arranged. Thus, the gap between the distribution apron 11 and the inner edge 23 is slightly increased, so that a larger partial flow of the rinse water flows directly into the bowl below the distribution apron 11. If the lower edge 25 is arranged at the same height as the inner edge 23 or at most 2 cm higher than the inner edge, in particular a maximum of 1 cm, in particular a maximum of 0.5 cm higher than the inner edge 23 is arranged, unwanted splashing out of the rinse water at Simultaneous improvement of rinsing performance avoided. The position of the inner edge 23 and the lowest point of the lower edge 25 is based on the same reference point, for example on the ground. In other words, the inner edge 23, for example, where it intersects the central longitudinal axis, a first distance to the ground. The lower edge 25 has, where it also intersects the central longitudinal axis, a second distance to the ground. The distance between the lower edge 25 and the inner edge 23 corresponds to the difference between the first and second distances.

The angle of inclination of the distribution apron 11 corresponds approximately to the angle of inclination of the toilet bowl below the distribution apron 11. In other words, the distribution apron and the wall of the toilet bowl below the distribution apron 11 extend substantially parallel at least in the upper region near the inner edge 23rd

The position of the lower edge is in Fig. 9 in connection with the continuously extending distribution apron 11. The above-disclosed position of the lower edge is also in connection with the embodiments according to Fig. 5-8 disclosed.

The rinsing water, which is deflected in the circumferential direction in the region of the distribution apron 11, flows along the edge of the bowl 10 during rinsing, whereby a part of the rinsing water runs down into the bowl and rinses the rinsing region 21. For this purpose, the bowl edge 10 has a circumferential, in the embodiments according to FIGS. 4 and 5 completely encircling projection 13, which forms a skirtless water supply. The water supply is schürzenlos, because in this area downwardly projecting fittings are missing.

As in the FIGS. 4 and 8th To recognize, the projection 13 runs completely around. This means that the projection 13 and thus also the water supply extend along the entire circumference of the bowl rim 10. The water guide is fluidly connected to the distribution apron 11. This means that the rinsing water, which is deflected by the distribution apron 11, enters the water guide during rinsing and is distributed from there to the circumference of the bowl and flows into the bowl.

At this point it is made clear that the projection 13 on the one hand forms the skirtless water flow outside the area of the distributor skirt 11. On the other hand, the projection 13 forms in the region of the distribution apron, the upper limit of the toilet bowl. The water guide and thus the projection 13 are thus sections without a skirt, in the area outside the distribution apron 11, as shown in all figures. The skirtless section of the toilet bowl is 65% to 75% of the total.

As can be seen in the figures, the projection 13 has a horizontal first wall 14. The horizontal first wall 14 extends radially inwardly and closes the bowl rim 10 upwards. This is good in the FIGS. 4 and 8th to recognize. The bowl rim 10 has a further downwardly extending second wall 15. The direction "down" refers to the state of use of the toilet. The first and second walls 14, 15 are angularly connected to each other and define a laterally and downwardly open hollow channel of the water supply. In other words, form the two walls 14, 15 in the circumferential direction of the bowl edge 10 extending L-shaped angle profile, wherein a leg of the angle profile is arranged horizontally (horizontal first wall 14). The angle profile is curved in the circumferential direction of the bowl.

The horizontal first wall 14 is flush with an upper edge of the bowl rim 10, as particularly in the FIGS. 4 and 8th to recognize. The horizontal first wall thus forms the top of the toilet bowl. In the region of the inner edge of the first wall 14, a rounding can be provided, which gives the bowl edge a pleasing appearance. The first wall 14 extends radially inward to the extent that a secure protection against spewing rinse water is achieved. For this purpose, a wall width of 2 cm to 6 cm suffice. The downwardly extending second wall 15 is slightly inclined inwardly. Other orientations of the second wall are possible and can be chosen essentially freely by the designer. The bowl edge 10 has a peripheral shoulder 16, which limits the hollow channel 24 down. The heel 16 extends parallel to the first wall 14 and causes the bowl rim 10 to protrude outwardly in the region of the water guide. On the one hand a good water flow is achieved. On the other hand, influenced by the outwardly projecting bowl edge 10 of the overall aesthetic impression of the toilet bowl. Again, other embodiments according to aesthetic or technical aspects are possible.

In the present embodiments, the first and second walls 14, 15 have the same wall thickness. Overall, the wall thickness of the two walls 14, 15 corresponds to the wall thickness of the bowl in the flushing area 21.

In contrast to the embodiment according to Figures 5-8 The embodiment according to FIG Figures 1-4 a continuous transition between the horizontal first wall 14 and the distribution apron 11. This can be clearly seen in FIGS. 1-4. For the continuous transition, the first wall 14 widens, with the wall widening leaving the horizontal plane and curving downwards. The first wall is continuously in the baffle plate of the distribution apron 11 over. This also applies to the inner edge of the second wall 15, which extends continuously in the region of the broadening down and merges into the distribution apron 11. Thus, on the one hand, an extension of the distributor skirt 11 in the circumferential direction is achieved, so that the guiding effect and thus the safety against spewing rinse water is improved. On the other hand, the curved shape causes a special aesthetic effect.

As in Fig. 3 illustrated, the distributor skirt 11 and the continuous transition are formed symmetrically, so that the mentioned improvement acts in both circumferential directions. The angle of inclination of the continuously downwardly extending inner edge of the first wall can be varied.

In the embodiment according to Figures 5-8 instead of the continuous transition, a transitional edge 17 is provided which is formed between the horizontal first wall 14 and the distribution apron 11. Thus, an abrupt transition between the distribution apron 11 and the first wall 14 is achieved, whereby a different overall impression of the toilet is achieved, as in the embodiment according to Figures 1-4 , Technically, the angular transition has the advantage that the overlap of the distributor skirt 11 with the inner edge 23 along a larger portion of the circumference is possible than in the embodiment according to Figures 1-4 ,

In both embodiments, the distribution apron extends along a partial circumference of the bowl rim 10, which is 25% to 35% of the total circumference.
