    The invention relates to an overflow for a sink according to the preamble of claim 1, with at least one inlet opening, which is intended for mounting on a basin of the sink or on an overflow well or a separate spout, and with an outlet opening, the is intended for mounting on a drain or vent valve of the basin or the sink, wherein between the inlet opening and outlet opening a flow channel for a fluid or water is arranged.
    The invention also relates to a sink with at least one overflow, which sink comprises an opening in a side wall of a sink or an opening in a horizontal surface of the sink, preferably in the region of an overflow trough or a separate spout, which opening via an overflow fluidly connected to the drain of the sink, according to the preamble of claim 14.
    Furthermore, the invention relates to a retrofit element for such a sink with overflow, which retrofit element is adapted to be used in the existing overflow of the sink.
    Rinsing known type, especially kitchen sinks, regularly have an overflow, as defined above, so that at a closure of the actual rinse cycle excess water from the sink or an overflow tray can run when the water level has reached a certain level or if water in the overflow well or the spout passes, eg from a drainer of the sink. This should avoid flooding and corresponding damage.
    In the past, it has sometimes proved difficult to ensure proper overflow function, which must be able to regularly drain a relatively large amount of water of up to 12 l / min from the sink. For example, elaborate and correspondingly costly vents for the overflow have been provided for this purpose so that it can fulfill its safety function at any time without restriction. In particular, in the drainage of overflow wells or separate spouts has been shown that the necessary for proper functioning dynamic pressure is difficult to achieve.
    The invention has for its object to provide an improved overflow in a simple and cost-effective manner, so that from the basin and / or the overflow trough or the separate spout overflowing water can be optimally and safely dissipated. Preferably, this solution should be retrofitted even with existing sinks without major construction effort (retrofitted).
    The object is achieved by an overflow with the features of claim 1, by a sink with the features of claim 14 and by a retrofit with the features of claim 15. Advantageous developments of the respective subject invention are defined in the corresponding dependent claims.
    According to the invention, an overflow for a sink, preferably a kitchen sink with at least one sink and an overflow trough or a separate spout, with at least one inlet opening, which is intended for mounting on the basin or on the overflow trough or the separate spout, and with an outlet opening which is intended to be mounted on a drain or ventilation valve of the sink or basin, wherein a flow channel for a fluid is arranged between the inlet opening and outlet opening, characterized in that at least one section (flow channel section) is provided in the flow channel is, in which the flow channel has a substantially circular cross-section.
    The overflow may in particular also have two or more inlet openings, one of which is at the basin and another at the overflow trough or the separate spout or another basin - if available -montiert or mountable. In addition, the realization of several separate overflows according to the invention is possible, e.g. for every sink or for sink and overflow trough or spout.
    According to another aspect of the invention, a sink according to the invention with at least one overflow, which sink comprises an opening in a side wall of a sink or an opening in a horizontal surface of the sink, preferably in the region of an overflow trough or a separate spout, which Opening is connected via an overflow fluidly connected to a drain of the sink, characterized in that the sink has an inventive overflow according to one of claims 1 to 13.
    Furthermore, the invention provides a retrofit element for a sink with overflow, which sink comprises an opening in a side wall of a sink or an opening in a horizontal surface of the sink, preferably in the region of an overflow well or a separate spout, which opening on the Overflow fluidly connected to a drain of the sink, which retrofit element is adapted to be fitted into the overflow, wherein an outer contour of the retrofit element substantially corresponds to an inner contour of the overflow in a region, and wherein the retrofit element has at least one opening, the inner contour has a substantially circular cross-section.
    According to the invention, it is accordingly provided that in the defined between the at least one inlet opening and the outlet opening of the overflow flow channel at least a portion is provided in which the flow channel has a substantially circular cross-section, even if the flow channel itself - which is the rule is - has a deviating cross-sectional geometry. Said flow channel section with circular
    Cross-section, when draining liquid through the overflow, provides vortex formation similar to that of an upturned bottle when it is set in motion about its longitudinal axis. As a result, there is less jammed air in the system, and drainage of fluid through the overflow is improved. This has a particularly beneficial effect, especially with overflow wells and separate spouts, because a back pressure can not really build up in this arrangement.
    In a further development of the inventive overflow can be provided that the flow channel in the section has a constant cross-section, which can have a favorable effect on the vortex formation. This can at least apply to a large part of the section mentioned above.
    Alternatively it can be provided that the flow channel in the section, seen in the flow direction of the fluid, at least one, for example, conical taper of its cross section. This may for example be the case in the region of the inlet opening. Furthermore, the flow channel in the section can also have an extension of its cross section, preferably in the region or in the direction of the outlet opening.
    In order to further optimize the aforementioned vortex formation, another development of the inventive overflow is characterized in that the section has a certain length L, which may be numerically linked to a diameter D of the section. The following may hold: L> f * D. The factor f may be between about 2 and about 5, and in turn may depend on the diameter D, f = f (D).
    As a particularly advantageous for the flow behavior in the overflow has been found when several of said sections are arranged in parallel in the flow channel.
    In order to allow a sufficient overflow of up to 12 l / min, provides another development of the inventive overflow that a sum of the cross sections of the sections, if more such sections are present, or the cross sections of an existing section in the area of about 175 mm 2, most preferably between about 150 mm 2 and about 200 mm 2.
    In order to adapt a component geometry of the overflow as flexible as possible, provides another development of the inventive overflow that the (several) sections next to each other, on a line, in the manner of a triangle, offset, in zigzag or in another relative position are arranged to each other, preferably in each case based on the position of their centers.
    Furthermore, it may be advantageous if the (several) sections are formed substantially identical to each other, but without the invention being limited thereto.
    The at least one section or at least one of said plurality of sections may be arranged in the region of the inlet opening of the overflow, for example in the region of a so-called overflow head. The overflow head is that part of the overflow which is physically mounted directly in the region of an overflow opening of the sink or of the sink at this or on this. The same applies to the inlet opening in the region of an overflow trough or a separate spout.
    Alternatively or additionally, however, it may be provided that the at least one section or one of the plurality of sections is arranged in the region of the outlet opening of the overflow, that is to say rather in the direction of the flushing outlet.
    In principle, however, the circular flow channel section can also be arranged at any other point of the overflow or the overflow flow channel. Accordingly, another development of the overflow according to the invention provides that the at least one section or at least one of the several sections is arranged in the region of an angle piece of the flow channel, which angle piece a first, when mounted vertical portion of the flow channel in a second, in assembly horizontal section the flow channel transferred. In this case, the at least one flow channel section can be arranged in the region of the first section (ie vertically) and / or in the region of the second section (ie horizontally).
    With regard to the retrofit element according to the invention, it has already been pointed out that this is designed to be fitted into an existing overflow. In this case - as already stated - an outer contour of the retrofit element substantially correspond to an inner contour of the overflow in a region. In this way, the retrofit element can be used inside, as a kind of use, in an existing overflow. This can in principle be done anywhere in the overflow, e.g. also in the overflow head. However, the above-mentioned overflow head, if it includes the said circular flow channel section, can already be regarded as a retrofit element itself because it can replace an existing overflow head of an existing overflow. The same applies to the addressed angle piece or angle part or any other portion of an existing overflow flow channel: this can be retrofitted according to the invention by being exchanged for a corresponding part, which has at least one circular flow channel section. Accordingly, the retrofit element then forms at least a partial section or segment of the overflow flow channel.
    In this way, virtually all existing overflows can be retrofitted in a simple and cost-effective manner for the purposes of the present invention flow-optimized.
    Further features and advantages of the invention will become apparent from the following description of exemplary embodiments with reference to the drawings.
    Fig. 1 shows schematically, partially in section, a sink according to the invention with an inventive overflow;
    Fig. 2 shows the overflow head of an inventive overflow in a perspective view;
    Fig. 3 shows the overflow head of Figure 2 in another perspective view.
    Fig. 4 shows various other views of the overflow head of Figures 2 and 3.
    Fig. 5 shows schematically an alternative embodiment of the sink of Figure 1, partially in section.
    Fig. 6 shows an alternative rinse mold with overflow trough; and
    Fig. 7 shows a further alternative Spülenform with separate spout.
    In Fig. 1 is a schematic and partially in section a sink, in particular a kitchen sink, shown, which is generally designated by the reference numeral 1. The sink 1 comprises at least one sink 2, of which only a lower corner area is shown, which comprises a pool wall 3 and a pool floor 4. In the pelvic floor 4, a drain opening is provided at the reference numeral 5, which fluidly communicates with a sink drain 6, which is known per se. In the region of the drain opening 5, a sealing plug or valve plug 7 is arranged, which in the embodiment shown closes the drain opening 5 in a fluid-tight manner so that no water can flow out of the sink basin 2 through the drain opening 5. As a result, flushing water 2 is contained in the sink tank 2 up to a water level 9 shown schematically. The water level 9 is at the height of an opening 10 in the pool wall 3, which opening 10 can also be referred to as an overflow opening. Due to the selected representation, the opening 10 in Fig. 1 is not visible.
    In the region of the opening 10 is outside of the pool wall 3, the so-called overflow head 11 of a known overflow 12 is mounted over which overflow 12 water 8 from the sink 2 for flushing 6 can flow when the water level 9 within the sink 2 reaches or exceeds a certain level. The overflow 12 comprises, in addition to the already mentioned overflow head 11, an inlet opening 13 in the region of the overflow head 11, which inlet opening 13 communicates with the aforementioned opening 10 in the basin wall 3 of the sink 2. Around the inlet opening 13 around a seal is regularly arranged to seal the overflow head 11 fluid-tight against the pool wall 3. This seal is not visible in Fig. 1. 1, an angled overflow pipe 14 adjoins the overflow head 11, which at its end facing away from the overflow head 11 defines an outlet opening 15, via which the overflow 12 opens into the flushing outflow 6. Inlet opening 13, overflow head 11, overflow pipe 14 and outlet opening 15 define in this way a flow channel 14a from the opening 10 in the pool wall 3 of the sink 2 to the sink 6, so that water 8 can flow from the sink 2 through the overflow 12 when the water level 9 - as already stated - reaches or exceeds a certain level (a certain level).
    The embodiment described so far with reference to FIG. 1 is known per se and comes in commercial (kitchen) sinks, such as the sink 1 shown, used regularly. The present invention now relates to improvements in the area of the overflow 12, in particular of the overflow head 11, which will be discussed in more detail with reference to the following figures.
    Fig. 2 shows an overall perspective view of an overflow head 11 'of an inventive overflow, which is not shown in Fig. 2. For the further structural design features of the overflow reference is made to the already explained in detail Fig. 1.
    The overflow head 11 'according to FIG. 2 also includes the already mentioned, approximately rectangular inlet opening 13, which is surrounded by a correspondingly shaped sealing surface 16. Approximately in the center of the otherwise slightly funnel-shaped inwardly tapering inlet opening 13 is centrally approximately circular-cylindrical reinforced structure 17 is arranged, which forms a mounting hole 18 for attachment of the overflow head 11 'in the region of the pool wall 3 (see Fig .. 1). In a lower boundary surface 19 of the inlet opening 13 four openings or holes 20.1 to 20.4 are present side by side in a row, which extend parallel to each other through a connecting piece 21 of the overflow head 11 '. These apertures or bores 20.1 to 20.4 each define a flow channel section of the overflow 12 (see Fig. 1) and each have an approximately circular Guerschnitt, which is particularly apparent in the further perspective view in Fig. 3 well. The connecting piece 21 of the overflow head 11 'has on the outside protruding formations, which can serve for the attachment of a slidable tube or hose (not shown) or for reinforcing purposes.
    Fig. 3 shows the overflow head 11 'in a further perspective view obliquely from below, so that the formation and arrangement of the openings / holes or flow channel sections 20.1 to 20.4 can be clearly seen. These are - as already stated - next to each other on a line (relative to their virtual centers, not shown) and each have approximately the same diameter D. However, the invention is by no means limited to the arrangement, number or size design of the openings / bores 20.1 to 20.4 shown here.
    For example, the apertures / holes 20.1-20.4 may also have different diameters D, and there may be more or less than the four apertures / holes 20.1-20.4 shown. In addition, these may be arranged relative to each other in a different geometry, for example offset, in zigzag, in the manner of a square, triangle or the like, or it may, for example, only a single such breakthrough be present. It is essential in any case that the opening or the openings have or have an approximately circular diameter, although the connecting piece 21 of the overflow head 11 or its inlet opening 13 has a deviating geometry (oval or rectangular). The Applicant has found that the presence of circular flow channel sections significantly improves the overflow flow of the overflowing water, comparable to the improved leakage of water from an over-the-top bottle as it rotates about the longitudinal axis of the bottle becomes.
    The openings / holes 20.1-20.4 may have a terminal widening in the region of the inlet opening 13 and / or in the region of a free (lower) end of the connecting piece 21, as shown in Fig. 3 at 22.4 for the bore 20.4 is exemplified ,
    FIG. 4 shows further views of the overflow head 11 'according to FIGS. 2 and 3.
    In part of Figure 4a), the overflow head 11 'in a side view corresponding to FIG. 1 is shown. This is not discussed here. However, one recognizes the above-mentioned with reference to FIG. 2, the funnel-like taper of the inlet opening 13, starting from the sealing surface 16 inwardly (left in Fig. 4a).
    In part figure 4b) of the overflow head 11 'is shown in a view from the front. Clearly visible is the reinforced structure 17 with mounting hole 18 and the circumferential sealing surface 16th
    Figure 4c) illustrates the position of a section line B-B, which is shown according to the overflow head 11 'in the sectional view according to part of Figure 4d). Well visible in Fig. 4d), the location and design of the flow channel sections or openings / holes 20.1-20.4 with approximately the same diameter D, which can be identical for all four holes 20.1-20.4, which in Fig. 4d due to the selected Sectional view is not recognizable. Reference character L denotes an axial length of the flow channel sections or openings / bores 20.1-20.4, which may also be identical for all four flow channel sections and substantially the entire axial length L of the connecting piece 21 from the inlet opening 13 to its free End corresponds.
    5 schematically shows an alternative embodiment of the overflow according to the invention (designated by reference numeral 12 'in FIG. 5) in which, alternatively or in addition to the flow channel sections with a circular cross-section formed in the region of the overflow head 11, 11' Further) such flow channel section is provided in the region of the overflow pipe 14. Specifically, said further flow channel section is designated by reference numeral 20.5 and arranged in the region of an angle 14.1, which connects a first pipe part 14.2, which is connected in extension thereof to the connecting piece 21 of the overflow head 11, 11 ', with a second pipe part 14.3, which is connected to the sink outlet 6 and defines the outlet opening 15 of the overflow 12 '. The angle or angle part 14.1 is shown hatched in Fig. 5. Instead of the one shown further flow channel section 20.5, in turn, several such sections may be provided in quasi-arbitrary arrangement relative to each other, which was previously referred to above to Figs. 2 and 3 already. In this case, it is also possible for the at least one further flow channel section 20.5 to extend completely through the angle piece 14.1, that is to say also beyond its angled portion.
    As the person skilled in the art realizes, the at least one flow channel section 20.5 could alternatively also be arranged in the region of the first pipe part 14.2 and / or of the second pipe part 14.3. In all these cases, the present proposed improvement in the area of a (purge) overflow can also be realized by retrofitting an already existing overflow in an existing sink, for example, by retrofitting a corresponding pipe or elbow 14.1-14.3 or a corresponding use is used in an existing overflow. The same also applies to the overflow head 11 ', which can replace an existing, known overflow head 11.
    Without limitation, it has proven to be particularly advantageous if said diameter D of the openings / holes in the range of 2 to 35 mm, with smaller diameters D, a corresponding plurality of openings is to be provided. Applicant has found that a minimum cross-section summed over all apertures or bores should be in the range of about 150 mm 2 to about 200 mm 2, preferably about 175 mm 2. A preferred length L of the apertures / bores is about 5 to 150 mm and may be dependent on the chosen diameter D: L = f D, where f = f (D) may be between about 2 and about 5.
    The invention is not limited to the application in the area of a sink, but it can alternatively or additionally be used in the area of a so-called. Overflow well or a separate spout.
