Definitions

  • the present invention relates to a water closet, hereinafter referred to as toilet for short.
  • Toilets with a toilet bowl, a flushing water supply for it and a waste water drain usually connected via a siphon are common and well known.
  • additional functions such as shower facilities, odor extractors and the like have become the subject of further technical development.
  • Toilets have a toilet body which in particular comprises a hollow shape that is open at the top, namely the toilet bowl, and is normally, although not necessarily, made of ceramic. Further technical devices can be provided in the ceramic part of the toilet body or in add-on parts or behind or under covers on the ceramic body.
  • a conventional toilet body has a so-called flushing rim above or on the upper inner edge of the toilet bowl, namely a circumferential flushing water channel with downwardly pointing inlet openings for the flow of flushing water into the toilet bowl; it works like a ring-shaped shower when it comes to feeding the rinse water into the bowl.
  • toilets with a rotating flushing water flow in the toilet bowl are known which, due to a largely tangential entry of the flushing water into the bowl, ensure a vortex-like flow therein before the flushing water exits through the siphon and the waste water drain.
  • EP patent 2 604 761 B1 referred to the same owner, which concerns an asymmetrical and thereby a rotating movement of the flushing water generating or supporting toilet bowl inner shape. This results in good washing results with comparatively small amounts of washing water reached. In addition, it has been found that this toilet bowl works particularly quietly.
  • the WO 2004/022862 A1 describes a toilet with an inlet opening for flushing water, which is followed by an upper flow path that runs around the bowl opening. There are two other deeper flow paths.
  • the EP 1 847 656 A1 shows two flushing water inlet openings and flow paths adjoining them, the upper one of which also runs around the bowl opening.
  • the EP 3 085 842 A1 forms the generic term and shows an inlet opening and an adjoining and completely circumferential flow path. In addition, a deeper flow path with a downward shape is provided. The upper one should distribute the rinsing water over the entire inside of the bowl and the lower one should direct the rinsing water downwards.
  • the present invention is based on the object of specifying a further improved toilet bowl. This object is achieved by claim 1, which is explained in more detail below, as well as various preferred embodiments. Preferred embodiments of the device according to the invention and its use are specified in the dependent claims. The features contained therein and also the disclosure of the following description are to be understood fundamentally with regard to both categories of the invention, without always explicitly distinguishing between them.
  • the shape of the bowl opening is typically similar to the approximate shape of the inside of the bowl, at least in its upper area. Therefore, it makes sense to define the longest internal dimension through the shape of the bowl opening as the longitudinal axis and a perpendicular to it as the transverse axis. In the case of typical toilet bowls, this means that the user in a typical sitting position on the toilet looks in the direction of the longitudinal axis and his shoulders run in the direction of the transverse axis. In the case of wall mounting, the longitudinal axis is typically perpendicular to the wall and the transverse axis runs parallel to it.
  • overhanging shapes form undercuts which are disadvantageous in terms of production technology.
  • a smaller overhang or even the avoidance of undercuts, however, are advantageous in terms of production technology.
  • this in turn results in an increased risk of the described spilling over.
  • a flow path in the sense of this representation is understood as a path-like surface running in the inner wall of the toilet bowl and extending outwards, that is to say in the transition to the further wall leading upwards, delimited by a concave edge and inwardly, i.e. to the wall leading further downwards and in the direction of the outlet, delimited by a convex edge.
  • An edge is determined by a particularly strong curvature in a vertical section, in other words, mathematically speaking, by an extreme value of the curvature.
  • Such a flow path is used to guide or at least to support a certain water flow.
  • the water circles and is held against the inside wall of the bowl by centrifugal forces, but at the same time it is pulled downwards by gravity (more or less obliquely) so that variations in the shape of the inside wall of the bowl result in corresponding flow-guiding Have properties produced.
  • the tangential direction of entry of the flushing water is specified by the design of the flushing water inlet, that is to say by the inlet opening and the pipe section for the flushing water that adjoins it upstream.
  • Such a tangential configuration of the flushing water inlet is in itself already implemented in different forms in the prior art and usually serves the purpose of a rotating flushing water flow in the toilet bowl.
  • a second or an extension of the known flow path is provided in addition to one of the EP 2 604 761 B1 known (first) flow path.
  • This second or lengthened flow path is intended to prevent at least part of the flushing water from being directed too much downwardly and thus reduce or prevent the above-described “rocking”. If part of the flow through the second flow path is "held” at a certain height, there or downstream therefrom a less pronounced sagging of the total flow or also a meeting of the flow part running on and above the second or elongated flow path with a flow part running further down.
  • the rotating movement of the flow in the bowl and the position of certain properties of the inside shape of the bowl should be described with an azimuthal angle that appears from a certain position in the bowl (in plan view) to the intersection of the axes, namely as an angle to the longitudinal axis.
  • the point of the bowl opening closest to the wall lies on the longitudinal axis and thus at 0 ° or 180 ° azimuthal angle. Proceeding from this, there is then a lateral area in the area around 90 ° or 270 °.
  • the flushing water should be directed through the inlet opening onto a (with respect to a top view) concave curvature region of the inner wall of the toilet bowl, for which purpose the inlet opening is between 80 ° and 180 ° azimuthal angle.
  • the inlet opening is preferably at smaller azimuthal angles than 170 °, 160 °, 150 ° or even 140 ° and likewise preferably at least 90 °.
  • the flushing water flows out in the direction of larger azimuthal angles.
  • the inlet opening preferably lies in a quadrant upstream of a particularly concave curvature of the bowl opening and aims at this particularly concave point.
  • the mentioned and usually particularly strongly concave curved area of the toilet bowl can be at approximately 180 °, that is, at the end point of the longitudinal axis.
  • the value can also be at a slightly different azimuthal angle instead of 180 °, in particular in a range between 150 ° and 210 °, preferably 160 ° and 200 ° or 170 ° and 190 °. He does not have to fill in these angular ranges.
  • Such a sinking flow part could then hit the first flow path or the first flow path part provided according to the invention, which runs at least between 90 ° and 270 ° based on the azimuthal angle and preferably adjoins the inlet opening at the bottom in order to be able to guide the water exiting therefrom .
  • Preferred lower limits for the above angular range are 80 °, 70 °, 60 °, 50 °, 40 °, 30 °, 20 ° and preferred upper limits are 280 °, 290 °, 300 °, 310 °, 320 °, 330 ° and 340 °.
  • a second flow path or a second flow path part is provided according to the invention, again between an outer concave and an inner convex edge and higher than the part of the first flow path corresponding to the azimuthal angle or the next adjacent part first flow path part.
  • the second flow path or the second part should be provided at least between an azimuthal angle of 310 ° and 340 °.
  • Preferred lower limits are 300 °, 290 °, 280 °, 270 °, 260 °, the second flow path preferably not starting at angles below 200 °.
  • a preferred upper limit is 345 °, the second flow path preferably not being extended over 400 ° (that is to say over 360 ° 40 °) if it does not merge into the first flow path anyway.
  • the EP 2 604 761 B1 known flow path either be lengthened, where a continuous (simultaneously first and second) flow path remains, or a second flow path is added.
  • the difference is ultimately whether or not there is an interruption between the two flow paths or parts, in particular one at a 0 ° azimuthal angle, which will be discussed in more detail below.
  • the term second flow path is used, this being understood as the second flow path part of the same uniform flow path for the case without interruption.
  • first flow path which is a first part of the flow path without the mentioned interruption and as such (without the second part) already from the EP 2 604 761 B1 is known.
  • the second flow path should therefore in particular not be completely circumferential, but only cover a limited area, namely where experience has shown that there is a particularly great risk of the water flow running along the inner wall of the bowl sinking. This applies in particular to the "fourth quadrant" (counting from 0 ° onwards with an increasing azimuthal angle).
  • the second flow path at least partially supports the flushing water flow and thus prevents the already described mechanism of “reflection” from appearing too strongly on the first flow path.
  • EP 3 085 842 A1 two flow paths, of which an upper one, starting from the inlet opening, circulates completely and in a closed manner, while a second separate one is lower and leads downwards.
  • the previous line of argument does not depend on whether the definition of the azimuthal angle begins with the value 0 at the front or the back, whereby these terms refer to the usual sitting position of a toilet user, "back" i.e. the part of the inside of the bowl close to the bottom (on referred to the horizontal).
  • the previous argument does not depend on whether the direction of rotation of the flush water flow in the toilet bowl is left or right is whether the azimuthal angle increases clockwise or counterclockwise in plan view. The more frequent and preferred case is a clockwise direction of rotation when viewed from above.
  • the case is preferred that the azimuthal angle is calculated from the rear.
  • the flushing water flow is out of the inlet opening onto the Concave curvature of the inside of the toilet bowl is directed towards the front (and it would be directed towards the rear if the zero point of the azimuthal angle was defined in front). Both are possible, but the variant mentioned is preferred, especially in connection with a siphon drain located more at the rear.
  • the second flow path according to the invention so to speak a second or elongated shoulder in the bowl inner shape, prevented a partial sloshing of wash water out of the bowl, even with little or no undercut of the bowl inner shape at its upper edge.
  • the flushing water inlet opening absolutely requires an undercut and, in this context, an "undercut-free" bowl inner shape naturally has an undercut at the inlet opening. Rather, it is about the area just below the upper edge of the inside of the bowl, i.e. where the flushing rim is located on classic toilet bowls.
  • the invention basically strives for a form that is as simple as possible, easy to clean (and therefore smooth) and advantageous in terms of production technology. As already explained, an undercut-free interior bowl shape in the sense described is therefore preferred.
  • a restriction to the two or to the one described flow path is preferred, that is, the waiver of further ones.
  • the flow paths do not result in undercuts, at least preferably not, they complicate the shape a little and a clever design of the flushing water flow is not made easier by what the inventors consider to be an unnecessarily large number of different flow paths.
  • the first flow path in particular can have a considerable extent in relation to the azimuthal angle, but this does not change the fact that it is a coherent, uniform flow path.
  • the flow paths described with the present invention are intended to guide essential parts of the flushing water flow. This applies even more clearly to the first flow path than to the second, because in the second only a part, namely generally only a part flowing somewhat higher along the inner wall of the bowl, is covered by the second flow path.
  • the two flow paths are in any case relatively pronounced in terms of their width, the width being understood as the dimension along the inner wall of the toilet bowl and perpendicular to the longitudinal extension of the flow path, i.e. normally in relation to the local surface orientation downwards.
  • Preferred minimum widths at the widest point are 12 cm for the first and 0.8 cm for the second flow path, with the following values 13 cm, 14 cm, 15 cm for the first and 0.9 cm for the second flow path, 1 cm, 1.1 cm in that order are increasingly preferred.
  • the second flow path has less the task of guiding or supporting a rotating downward flow, but rather of preventing part of the water flow from sinking too much.
  • it can preferably run approximately horizontally (in relation to its longitudinal direction).
  • the flow path preferably slopes slightly with the direction of flow, that is to say with the azimuthal angle.
  • the first flow path in turn essentially corresponds to the explanations in that already cited EP patent 2 604 761 B1 the same owner and accordingly runs downhill with increasing azimuthal angle on the one hand and rotating along the inside of the bowl on the other hand in order to support a downwardly directed and rotating flushing water flow.
  • an asymmetrical inner bowl shape which, due to a lower position of the first flow path on one side than on the other side, similar to a helical shape, specifies or generates a downward movement through the inner bowl shape. Accordingly, the very good surface cleaning properties of a rotating flow in the bowl are combined with a comparatively more pronounced swing when entering the siphon. This means that the kinetic energy of the flushing water can be used twice, for example as a result of the height of the gradient compared to a cistern.
  • the shape of the inside of the bowl follows the gravitational downward tendency of the water flow and avoids some of the turbulence that is caused by the water flowing down regardless of the inside shape of the bowl.
  • the predominant tangential velocity component of the flushing water which is known per se and exiting the inlet opening into the bowl, relates, so to speak, to a projection of a mean flushing water path onto a horizontal plane.
  • the rinse water does not exit the inlet opening in the direction of the water level in the siphon but rather transversely, whereby the exact angle in a general sense is not important and this can depend on the individual geometry of the inlet opening and the subsequent first flow path.
  • the speed of the flushing water emerging from the inlet opening does not have to be exactly horizontal, but it is preferably essentially horizontal.
  • the toilet according to the invention can be used with different methods of flushing water generation in terms of supplying it with a specific flushing water pressure realize, especially on a pressurized water line, i.e. without a cistern.
  • a cistern is preferred because the invention allows the limited potential energy of the flushing water to be used particularly efficiently. This applies in particular to a concealed cistern in a mounting wall behind the toilet.
  • the amounts of rinsing water can be kept relatively small, which has economic and ecological advantages.
  • the maximum amount of rinse water is preferably below 6 I, preferably below 5.5 I and particularly preferably below 5 I.
  • the flushing water flow according to the invention allows good wetting and flushing action of the surfaces of the interior bowl shape that are affected by soiling, specifically, as explained, by a rotating and thereby falling flow. Accordingly, a conventional flushing rim, which was initially compared with a shower, can be dispensed with. This makes the toilet bowl easier to manufacture, but also to clean, because classic flushing rims are particularly prone to soiling and calcification, and the underside is very difficult to reach.
  • the invention offers the possibility of a smooth transition from the actual interior surfaces of the bowl to the upper edge of the bowl, that is to say the surface areas of the toilet bowl pointing upwards, in particular under a toilet seat ring.
  • the (preferably single) inlet opening following the rinse water supply can be relatively high in one embodiment of the invention, in particular higher than 5 cm and, in the following sequence, increasingly preferably higher than 5.5 cm, 6 cm, 6.5 cm .
  • a high inlet opening a large cross-section that is favorable to the flow can be achieved without impairing the inside shape of the bowl too much by the inlet opening, both in terms of the flow guidance and in terms of its aesthetic appearance.
  • the flow cross-section of the flushing water supply is preferably relatively large.
  • it can be over at least 8 cm 2 , preferably over 9 cm, along the extent of the flushing water supply inside the toilet, i.e. between including the inlet opening and the transition to pipe parts outside the actual toilet, i.e. in particular within an installation wall behind it 2 and particularly preferably over 10 cm 2 or even 11 cm 2 .
  • the kinetic energy of the flushing water can be used particularly well as a result of a gradient or a line pressure.
  • the second flow path maintains a certain distance from the inlet opening, specifically preferably at least 60 ° azimuthal angle, more preferably 80 °, 100 °, 120 °, 130 °. This relates to the case in which the first and second flow paths are not connected uniformly and to azimuthal angles increasing in the direction of the flow path.
  • the two flow paths each form a local reduction in the otherwise prevailing inclination of the inside shape of the bowl. According to a preferred embodiment of the invention, they should therefore not be present at the rear in the bowl interior shape, at least preferably with a definition of the azimuthal angle of zero at this point, that is, a flushing water flow from the inlet opening to the front. It has been found that an inner wall at the rear that runs as smoothly and steeply as possible in the middle is preferable with regard to the tendency to soiling and that this aspect justifies a limitation of the flow paths in such a way that they do not sweep over this rear center from the point of view of the inventors. Reference is made to the exemplary embodiment for illustration. In this case, the first and the second flow path are therefore separated from one another.
  • the second flow path should run below a relatively steep part of the bowl interior shape. Accordingly is an angle of inclination of at least 70 ° or even 75 ° to the horizontal in this part above the second flow path is preferred, namely between 310 ° and 340 ° azimuthal angle and preferably along the entire longitudinal extent of the second flow path.
  • This statement is also preferably valid for part of the length of the second flow path or for its entire length then also for the entire part of the interior bowl shape above it, up to an upper edge or rounding that forms the transition to the top of the toilet body.
  • the statements on the steep wall in part of the height apply to the entire inside shape of the bowl.
  • the steep walls support a good cleaning effect and a sufficient downward trend of the water flow.
  • the water flow should accordingly flow into the siphon with a clear downward tendency in order to be able to rinse it out well.
  • the second flow path or the second flow path part is preferably relatively high in the repeatedly mentioned angular range between 310 ° and 340 °, in particular above the first flow path (the first flow path part), insofar as this is also preferably above 270 ° azimuthal angle towards larger azimuthal angles and into the range at and above 310 ° azimuthal angles. Then the two flow paths (parts) are spaced from one another and arranged one above the other.
  • the second flow path (the second flow path part) is preferably at least 3 cm higher than the first flow path (the first flow path part), with 3.5 cm, 4.0 cm, 4.5 cm, 5.0 cm being increasingly preferred as the lower limit .
  • the second flow path or the second flow path part in the azimuthal angle range mentioned between 310 ° and 340 ° is preferably higher than the lower edge of the inlet opening for the rinsing water, that is to say again relatively high.
  • This lower edge is preferably at least approximately at the same level as the first flow path at this point, ie the inlet opening injects the water onto the first flow path.
  • the invention is preferably implemented with a toilet bowl which in any case has only a single inlet opening for flushing water in the upper area, that is to say above the first flow path.
  • a toilet bowl which in any case has only a single inlet opening for flushing water in the upper area, that is to say above the first flow path.
  • FIGS Figures 1 to 6 show the invention using two toilet bowls
  • the first embodiment in FIGS Figures 1 to 3 is designed for the installation of a shower device of a shower toilet and the corresponding recesses and openings in the second embodiment Figures 4 to 6 are omitted. These differences are not of particular importance for the invention, but they illustrate that the invention can also be combined very favorably with a shower toilet.
  • the Figures 1 and 2 show, in perspective oblique views, the toilet bowl 1 of the first exemplary embodiment with a conventional bowl opening 2, a rear-side (that is to say in FIG Figure 1 top right on the top and in Figure 2 breakthrough 3 for the installation of a shower facility (not shown) and with a lowering 4 of the upper edge of the toilet bowl at the rear part of the bowl rim around the bowl opening 2 for the passage of a shower arm (not shown) of the shower facility.
  • the inner shape of the toilet bowl 1 visible through the bowl opening 2 is of interest below.
  • the inlet opening 6 for the rinse water is not directed to the rear (slightly offset to the right) and to the left, as stated in the prior art, but begins laterally at about 100 ° azimuthal angle and is directed forward, i.e. towards larger azimuthal angles.
  • the rinsing water is accordingly applied to the first flow path, but not when it starts (at 10 °).
  • this second flow path 7 is also defined as the inner wall area between an (upper and outer) concave edge and a (lower and inner) convex edge.
  • the second flow path 7 runs between approximately 250 ° and approximately 350 ° in terms of the azimuthal angle. It is also designed to be slightly sloping, with an approximate inclination (based on a center line, not shown, between the convex and concave edge) of about 5 ° in the horizontal viewing direction.
  • the first flow path 5 has at z. B. 180 ° an inclination of only about 11 ° relative to the horizontal with a maximum width of 16 cm.
  • the mentioned width refers to the distance between the mentioned edges (most convex and most concave line), namely as the straight distance between them along the steepest direction, i.e. the shortest distance.
  • the inside walls of the bowl above and below the second flow path 7, on the other hand, are quite steep with an inclination to the horizontal of approximately 80 °, in particular also at an azimuthal angle of 0 °. How in particular Figure 3 and Figure 4 show, the bowl walls, starting from this, become even steeper towards the front and the inclination is about 89 ° at an azimuthal angle of 180 °. So it just avoids an undercut.
  • the inside of the bowl thus has no undercut, in particular not on the upper edge (and of course with the exception of the inlet opening 6).
  • the two flow paths 5 and 7 have a distance of about 6 cm in this embodiment, which is measured as the path width, namely between the convex edge of the upper flow path 7 and the concave edge of the lower flow path 5 and directly in the inclination of the following direction.
  • the second flow path 7 is therefore significantly increased compared to the first flow path 5.
  • Figure 4 shows on the one hand a side view of the rear area of the bowl interior shape and on the other hand a section through the bowl.
  • the section plane runs through the sealing water level in the lowest area of the toilet bowl, which is shown with 8.
  • the surfaces with a straight sectional profile in vertical section such as. B. the steep bowl inner wall above the flow paths 5 and 7, separates curved surfaces.
  • the two flow paths 5 and 7 actually have a central strip which is straight in this sense and which are each followed by curved strips at the top and bottom.
  • Figure 6 shows the second embodiment from FIG Figures 4 and 5 with the azimuthal angle graduation and some values.
  • 0 ° corresponds to the rear center of the bowl interior shape and 180 ° to the front center.
  • the azimuthal angle range defined in the claims for the flushing water inlet opening between 80 ° and 180 ° can be seen.
  • the minimum range for the flow path can also be seen between 90 ° and 270 °.
  • the limits of the minimum range (between 310 ° and 340 °) for the second part of the or the second flow path, according to the claim, are slightly offset clockwise from the drawn line at 300 ° and offset in the same sense next to the line at 330 ° should not extend beyond the angular range between 230 ° and 90 °.
