Definitions
- the present invention relates to a water closet (toilet) with a special configuration of the inside shape of the toilet bowl.
- Toilets have been known for a long time and are defined by flushing the inside of the bowl with water.
- the water may be supplied at a head or by line pressure via a flush valve and flush line to an inlet port to the bowl.
- the water is distributed around the upper edge of the bowl like a ring shower via a so-called classic flushing rim and flows downwards through a large number of inlet openings in order to reach a drain opening in the bowl along its inner shape.
- various forms of water flow circulating in the bowl inner mold for rinsing are known and common.
- the flushing water is guided into the bowl via at least one inlet opening with a largely tangential inlet direction and flows therein in a combination of a circulating and a downward movement.
- EP 2 604 761 B1 describes such a case, in which the inner shape of the bowl is designed asymmetrically.
- the flushing water inlet opening is followed by a flow path defined between an outer concave edge and an inner convex edge, which on the one hand runs around the drain opening and on the other hand falls during this circulation in order to promote the described combination of a circulating and falling flushing water flow and that To bring the flushing water to the drain opening with a relatively large amount of "impact".
- EP 3 412 840 B1 in which a further second flow path is provided over a limited angular range (defined in a top view of the bowl opening) with which the risk of spraying out can be minimized, particularly if the upper bowl inner edge is free of an undercut.
- the object of the present invention is to specify a toilet with a further optimized inner bowl shape.
- a toilet with a bowl which has a bowl opening at the top and an inlet opening for flush water to enter the bowl, and an inner bowl shape with a flow path which is defined between an outer first concave edge and an inner first convex edge wherein the bowl has a drain with a drain opening and wherein the first flow path circumambulates the drain opening and falls as it revolves, the first flow path adjoining an inflow stage at its lower end, the inflow stage between a part of the first concave edge and the second convex edge is defined on a side of the inflow stage remote from the first flow path and rises from the first concave edge to the second convex edge, whereby the inflow stage is designed for deflecting flushing water into the drain opening, with an end proximal to a water level in the drain opening the Inflow stage is directed in a projection from above onto an outer edge of the water level in a two-thirds area of the outer edge.
- the inner bowl shape of the toilet according to the invention has a (“first”) flow path defined analogously to the prior art cited.
- the outer “first” concave edge and the inner “first” convex edge are also defined here as lines of extreme curvature values (maxima and minima, depending on the concavity or Convexity). From these extreme values, extreme value lines or edges then result from the variety of possible vertical intersections te. In other words, the edges are lines of greatest curvature with respect to the profile shape of the bowl interior (as viewed from the outside in).
- the corresponding first flow path has a circumferential shape, with the term “circulating” referring to the outlet opening, specifically the water level therein.
- the first flow path drops during the orbit.
- This drop means that the shape of the flow path supports or, in other words, accommodates the downward tendency of the water flow, which is in any case unavoidable due to gravity and is also desirable for the flushing effect.
- the first flow path has a lower end at the lower part, and the present invention proposes a so-called inflow stage adjacent to this lower end.
- this is to a certain extent a “barrier” occurring at the lower end of the first flow path, although the term “edge” is not used here to distinguish it from the concave and convex edges addressed above.
- This barrier or inflow stage is defined between a convex edge and a concave edge, with the concave edge being the first concave edge delimiting the first flow path to the outside, at least where the first flow path and the inflow stage adjoin one another, while the first concave edge also defines the inflow stage Accordingly, the “second” convex edge is on the side of the inflow stage facing away from the first flow path.
- the inflow stage In the case of the inflow stage, one can accordingly also speak of an outer convex edge and an inner concave edge (in contrast to the outer concave and inner convex edge of the flow path).
- the Inflow stage in the sense of the barrier from the concave to the convex edge. It is designed to deflect flushing water flowing on the first flow path. Accordingly, the inflow stage, as explained in more detail below, runs from the outside to the inside towards the outlet opening.
- the orientation of the inflow stage on the outlet opening refers to the view from above, i.e. to a vertical projection from above. Accordingly, there is an end of the upstream stage that is proximal to the water level. This proximal end is intended, again in projection from above, to be directed towards an outer edge of the water table in a front two-thirds area thereof.
- “In front” means from the user's point of view in front, ie from the user's standing in front of a toilet or adjacent to the knees of a user sitting on the toilet. Usually “in front” is directed away from the wall on or in front of which the toilet is or is to be installed.
- Directed means that the proximal end meets the outer edge of the water table or, if the flow stage extends beyond the outer edge, cuts, or if the flow stage ends before an extension of the proximal end meets the edge.
- the water level should not be understood to mean that water actually has to stand in the drain opening. Rather, a toilet with the usual odor trap is designed in such a way that in the installed position in the "rest state", i.e. without flushing water flow, there is a certain (maximum) water level in the drain opening. This does not include conceivable evaporation losses, which can lead to a slightly lower water level.
- the water level is typically determined by an overflow edge on the other side of the odor trap, i.e. on the side facing the sewage system.
- the above statements not only apply to the front two-thirds of the water level, but apply to the front half and most preferably even for the front third.
- the impact point of the inflow stage is on the outer edge, approximately at the splitting ratio of 3:1, ie at the edge of the front quarter.
- the inflow stage ends above the outer edge of the water level and no longer reaches it (which is not preferred, but possible). Then, in the sense of the present definitions, the end of the inflow step that is proximal to the edge (in projection from above) should be thought of as extended in the sense of its local direction. In the same way, one can consider the likewise conceivable, although not preferred, case that, in contrast to the exemplary embodiment, the inflow stage is not delimited by such a lower concave edge that is a direct continuation of the outer concave edge of the first flow path (i.e. the "first" concave edge).
- an intermediate piece can be thought of as an extension of the distal end (with its local direction in vertical projection) between an end of the inflow stage distal from the outer end of the water level and the outer concave edge of the first flow path.
- the lower concave edge of the inflow stage should also apply as the “first” concave edge in such cases, although there may be a gap between that and the outer concave edge of the first flow path. In this sense, the first flow path "ends" at the inflow stage or the inflow stage forms the lower end of the flow path.
- the described alignment of the proximal end of the inflow stage on the front two-thirds area serves to align the part of the flushing water deflected by the inflow stage in such a way that it does not hit the outlet opening, more precisely the water level, all the way “back” (in the sense defined above).
- another portion of the flushing water that has flowed on or near the first flow path can pass beyond the inflow stage instead of flowing along it to the drain opening. this part then hits the drain opening further back.
- at least two parts of the flushing water flow one part of which is directed a little further forward into the drain opening than the other by the inflow stage.
- the first flow path is used for a vortex-like and on the one hand rotating flushing water flow, on the other hand descending into the drain opening, which accordingly also leads to a rotating and in the drain opening
- the flushing water flow is as “sweeping” as possible.
- floating objects in particular, such as toilet paper collect and are not flushed out or not flushed out particularly quickly despite the otherwise extremely efficient (especially with regard to faeces) flushing water flow. If now, with the inflow stage, a part of the flushing water flow deviating from this rotating flow in the drain opening is aimed further forward into the same, such phenomena can be reduced or prevented.
- the impact angle of the proximal end of the inflow step or its extension on the outer edge of the water level is not too small, namely at least 30°, preferably at least 40°, 50°, 60° or even 70°.
- the inflow stage is therefore preferably not tangential to the outer edge in order to further promote the effect described.
- the inflow stage preferably has a certain minimum height of, for example, 10 mm, preferably even at least 12 mm or 14 mm. Conversely, the height is preferably less than 30mm, 28mm, 26mm or even 24mm. In the exemplary embodiment, the value is approximately 20 mm.
- the inflow stage should not have the minimum heights mentioned over its entire extent, but at least at its highest point.
- a curved shape of the inflow stage is also preferred, whereby this should run concavely from the perspective of the water flowing on the first flow path.
- the concave arcuate shape preferably covers an angle of at least 30°, preferably at least 40° or even at least 50° or 60°. In the exemplary embodiment, it is almost 90°.
- the definition of the distal end of the inflow stage will be discussed further below. This and the proximal end are decisive for the angular feature.
- the area “on the other side” of the flow stage, so to speak is preferably designed as a further flow path, namely as a second flow path.
- the edges delimiting this second flow path are on the one hand the second convex edge already discussed in connection with the flow stage and on the other hand a second concave edge on the side of the second flow path facing away from the inflow stage.
- this flow path then preferably runs directly in the vicinity of the water level or leads into it (depending on whether a convex extreme value line still occurs above the water level).
- this second flow path forms a favorable area of the inside shape of the bowl for the fundamentally desired rotating and falling flushing water flow. Accordingly, the second flow path preferably also slopes down, although typically it extends less far than the first flow path in terms of encircling the drain opening and the water level therein and accordingly also typically accounts for less difference in height.
- the second flow path described should not be confused with the second flow path described in EP 3 412 840 B1.
- a further flow path according to this document also exists in the present exemplary embodiment and in the present context it is also a preferred embodiment feature of the invention. However, it is discussed here with lower priority because it is less connected to the flow stage than the second flow path, and is therefore also referred to as the "third" flow path.
- the third flow path has the same function and shape as in the cited document, so that details can be referred to there. In contrast to this third flow path (e.g.
- the second flow path preferably has at least and particularly preferably exactly three pointed ends (again in a projection from above), whereby, as discussed above, alternatively one to the Water level proximal convex edge or the water level itself form a boundary line.
- the third flow path has exactly two pointed ends and, taking into account the height dimension (i.e. not only in vertical projection), neither borders on the water level nor comes particularly close to it.
- the third flow path has a step below itself and in the exemplary embodiment between itself and the second flow path, which could be defined analogously to the inflow step. This step has a significantly greater height than the inflow step, namely about 60 mm in the exemplary embodiment (and preferably at least 40 mm, preferably at least 45 mm or 50 mm).
- the second flow path is relatively wide (and the third quite narrow, in each case meant in the vertical projection), namely in a direction transverse to the longitudinal direction of the toilet, i.e. in its width direction, at least 30 mm, preferably even at least 30 mm, preferably even at least 35 mm or 40 mm (in the exemplary embodiment it is 45 mm).
- the first flow path runs around the outlet opening, specifically the water level. If this water level defines a crossing point of the axes and thus a center point with a longitudinal center axis in the direction from front to rear (as previously defined) and with a transverse center axis dividing this in the middle, and thus a center point, starting from this center point, a minimum quantitative statement can be made about the circulation .
- the first flow path can be represented by a center line between the first convex and the first concave edge (in vertical projection). Respective connecting lines between points of the center line and the one just defined The midpoint then preferably covers at least 160°, 170°, 180°, or even 190°.
- the fall of the first flow path during circulation makes it possible to distinguish a lower side from a higher side of the first flow path.
- “circulation” also means that the flushing water, insofar as it follows the first flow path, ultimately loses height, with local deviations not necessarily being ruled out.
- the first flow path should preferably fall monotonously (in the mathematical sense, ie without an intermediate rise), preferably strictly monotonously (ie also without horizontal intermediate areas).
- the center line just defined is to be used again as a reference line.
- the geometric features of the inner bowl shape described so far are preferably realized in a one-piece design, for example in a one-piece plastic molded part or ceramic part.
- the bowl below its bowl opening preferably has a one-piece inner bowl shape containing the first flow path and the inflow stage.
- a separately designed supply line can be connected to the inlet opening for the rinsing water.
- separate elements that are additionally provided in the bowl inner shape are excluded, ie, for example, an attached inflow step, which is glued on as a separate part, for example.
- the inflow stage should be formed in the bowl material itself.
- an end of the inflow stage that is distal to the water level should be aligned and arranged in such a way that an extension line of this distal end with the local direction (in projection from above) meets the upper edge of the inner bowl shape in the front half thereof, preferably even in their front third or even their front quarter. Accordingly, the inflow stage begins reasonably far in front and has a small or vanishing angle to the steep wall rich, from which the inflow stage grows out, with which the deflection function of the inflow stage can be implemented particularly well. In the exemplary embodiment, this transition into the steep wall area is tangential.
- the water level is in the rear two-thirds of the bowl opening (in vertical projection) with respect to the longitudinal direction (from front to back), preferably in the rear half as in the embodiment.
- the longitudinal axes on the one hand the water level and on the other hand the bowl opening) are taken into account.
- the distal end of the inflow stage is defined by the foremost end of the second flow path in cases in which the first concave edge delimiting the inflow stage continuously transitions into the area in which it only externally delimits the first flow path, compare the exemplary embodiment. Because of the seamless transition of the concave edge, the separation of the second convex edge, which delimits the inflow stage on the one hand and the second flow path on the other hand, must be used for the definition. If there is no such seamless transition of the concave edge, i.e. a distinction can be made between the first concave edge as the boundary of the first flow path and as the boundary of the inflow stage, the front end of the first concave edge in the area of the inflow stage is to be understood as the distal end.
- the exemplary embodiment illustrates this relationship.
- the inflow stage should preferably achieve a certain minimum steepness, namely an angle of rise relative to the horizontal of at least 75°, preferably at least 80° or even 85°. This is reached between the two limiting edges, ie between the second convex edge and the first concave edge.
- the third flow path already mentioned above can also be designed to run completely around the outflow opening, ie continuously. This helps distribute the flush water over the entire interior of the bowl for particularly small amounts of flush water.
- the first flow path preferably follows the inlet opening in the sense that the flushing water entering from it flows through it and distributes this flushing water further. i.e. not necessarily that all flushing water flows on the first flow path; on the contrary, a part will regularly flow further outwards, i.e. outside the first concave edge and, due to the speed, in a steeper area of the bowl wall and a further part will also flow further down over the first convex edge inwards.

- Figures 1-3 show the inside shape of the bowl by shades of gray, the other figures in lines.
- FIG. 10 a second convex edge 13 of a second flow path 14, which will be explained in more detail later, and a second concave edge 15 of the second flow path 14.
- FIG the first flow path 10 defining edges 11 and 12 central line.
- FIGS. 2, 4-6 show an inlet opening 17 for the rinsing water, which is connected to the rinsing water connection piece 18 in a way that cannot be seen. In the case of a flush with the toilet 1 connected, flushing water flows out of this inlet opening 17 with an approximately tangential (as viewed from above) and otherwise approximately horizontal main flow direction into the toilet bowl 2.
- the flushing water obviously hits the largest area of the first flow path 10 in terms of area ( Figure 5), which is connected to the inlet opening 17 in this sense.
- the first flow path 10 drops continuously and strictly monotonically, in particular with its center line 16, and in the process runs around (again with the center line 16 as a reference) the water level 8. Because of the quasi-asymptotic narrowing of the first flow path 10 at its beginning in In the aforesaid rear area, one could actually use the rearmost point of the inner shape of the bowl as the starting point in a mathematical sense, which results in an angle of this run around the water level 8 (based on the center point drawn therein and defined starting from the center line 16) of a good 230° leads.
- the outer concave edge the so-called first concave edge 11 runs approximately at the bottom during the described circulation of the first flow path 10
- Edge of the previously mentioned steep wall area 3 of the inner bowl shape compare for example the X marking on the left in Figure 3 and of course also Figure 4. This applies clockwise from “back” to "bottom” and a bit further. Then it runs continuously, arcuately and concavely further inwards, with additional structures being created between it and the steep wall area 3 according to FIG.
- FIG steep wall area 3 a stage, namely the inflow stage 18, branches off.
- This inflow stage 18 continues inwards in a concave curve and ends in the entrance area of the outlet opening, slightly above the water level 8.
- the inflow stage 18 begins relatively far forward, i.e. far in the front half of the bowl opening 2, as shown in FIGS. 4-6. (In Figure 4-6, the center line between the edges 11 and 13 is drawn in solid and numbered 18 because it represents the inflow stage.)
- Figure 1 clearly shows that the inflow stage 18 offsets the first flow path 10 a bit in height, with its qualitative shape then, i.e. clockwise according to Figure 4 beyond the flow stage 18, continuing in a similar way to, for example, the ones cited at the beginning both EP documents.
- the flow path is considered to be defined between an outer concave and an inner convex edge, it is logical to consider the first flow path 10 terminated by the inward shape of the first concave edge 11 as a result of the inflow step 18; hence the course of the center line 16 in Figure 4, which clearly bends inwards.
- the second convex edge 13 and the second concave edge 15 define a second flow path 14 between them, wherein in Figure 4 the second convex edge 13 bends just before the edge of the drain opening because that is where the strongest convex curvatures occur.
- the second concave edge 15 forms in a certain sense, apart from that caused by the inflow Stage 18 conditional height offset, a continuation of the first concave edge 11, compare Figures 1 and 4-6.
- the second flow path 14 thus has a pointed end at the front and rear, seen from above, and another corner approximately in the middle on the inside.
- the second flow path 14 is also significantly wider than the third flow path 19, namely about 45 mm. This refers to the transverse direction according to Figures 4-6, i.e. to the widest point at the inner corner of the second flow path 14.
- FIG. 8 shows the water flow just described with a photo of a real exemplary embodiment analogous to the other figures.
- the perspective corresponds to the plan view of Figures 4-6.
- the water is colored, which explains the dark tint, especially in the lower area. For the rest, reference is made to the explanation given just above.
- the exemplary embodiment also shows a third flow path 19, which has already been mentioned further from the abstract, clearly above and in the perspective from above offset somewhat clockwise from the leading edge 18.
- this third flow path 19 shows part of the rotating flushing water flow, which initially runs outside the first flow path 10 and because of the centrifugal force on the steep wall area 3, at a certain height. On the one hand, this part is somewhat prevented from sagging too much downwards, in particular after it has flowed through the lower region of the inner shape of the bowl in FIG. 4 and the radii of curvature relevant to the centrifugal force increase.
- the line 20 is a tangent to the outer edge of the water level 8 and the line 21 is an extension of the proximal end of the inflow step 18 up to this edge. Both lines 20 and 21 meet at an angle of almost 90°, with line 21 being directed approximately to the center point of the water level 8 .
- the intersection of the line 21 with the edge of the water level 8, as far as the longitudinal direction from front to back is concerned, according to Figure 6 is clearly within the foremost third of the central longitudinal axis of the water level 8, namely approximately at three quarters (and thus divides this central longitudinal axis in the ratio 3 :1).
- the part of the flushing water flow deflected by the inflow stage 18, although it aims approximately in the middle of the water level 8, is not too strongly deflected from the original main flow direction of the flushing water flow and can therefore still contain a significant part of the original "swing" (i.e. the kinetic energy and momentum).
- the drain opening and thus the water level 8 are clearly arranged in the rear area of the bowl opening 2 .
- Figures 5 and 6 also show that the direction of line 21, i.e. the local direction of the inflow stage 18 at its inner end, is rotated by almost 90° in relation to the local direction of the inflow stage 18 at its outer end, i.e.
- the inflow stage 18 in relation to the part of the Inflow stage 18, where this disappears on the outside or merges into the steep wall area 3 (in Figures 4 and 5 where the edges 13 and 15 meet).
- the inflow stage 18 thus spans a substantial angular range, which is the case in a manner that is very streamlined due to its concavely rounded shape.
- the height 22 is the vertical offset between the first concave edge 11 and the second convex edge 13 and thus to a certain extent the height of the inflow stage 18, while the height 23 is the vertical offset between the second concave edge 15 and the inner convex edge of the third flow path 19 is, ie the height of the third flow path 19 above the second flow path 14.
- the latter is significantly larger and is about 60 mm compared to about 20 mm for the former.
- these heights are shown without the (dash-dotted) edges shown in FIGS. 4-6; but they relate to these, in particular with the numerical values just given.
- the inflow stage reaches a steepness of approximately 90° relative to the horizontal.
- the entire toilet bowl 1 is a one-piece ceramic part, which applies in particular to the full inner shape of the bowl.
- FIG. 8 also otherwise shows the previously described detail, albeit not with a clarity comparable to the line drawings due to the photographic representation.
