Definitions

  • the invention relates to a flush toilet according to the preamble of patent claim 1.
  • Flush toilets have been known for some time, with each toilet being equipped with a flush.
  • the flushing of a flush toilet has two main functions. On the one hand, the flushing should serve to flush the entire inner surface of the toilet bowl in a cleaning manner and, on the other hand, solids and dirty water should be removed from the siphon by the flushing or by means of the flushing.
  • the characteristics of a functionally successful flush toilet are to clean maximum interior surface area of the toilet bowl and to remove solids and water from the siphon with maximum flushing power, both cleaning the toilet bowl surface and flushing the siphon being splash-free.
  • design features such as a hygienic surface, an easy-to-clean design without dead corners and a quiet flush are desirable. These properties are often antagonistic and compromises must be made to achieve a required balance of functionality, performance, design and manufacturability.
  • the size, shape and design of a toilet bowl has a significant influence here, since with a large inner surface of the toilet bowl to be cleaned, the inflowing water jet is usefully deflected and in the Drum must be distributed so that the entire drum surface is covered, or is applied with rinsing water.
  • a water distributor is often used for this purpose, which is arranged between the water inlet and the toilet bowl and divides the water into several partial flows in order to clean the toilet bowl.
  • a water distributor In conventional rimmed toilets, such a water distributor is located in the center of the back wall of the toilet and is structurally formed as part of the rim, although it may have physical dimensions that extend locally downward and/or out of the rim into the toilet.
  • the flushing water is routed around both concave inner sides of the toilet bowl, with some water being routed directly down into the siphon, depending on the water distributor.
  • Such water distributors are also found in modern "rimless” toilets, these water distributors being located in the center of the upper rear wall of the bowl. Since these "rimless” toilets do not have a rim, the water distributors used in "rimless” toilets are usually arranged in such a way that these water distributors protrude into the toilet bowl, so that the emerging water jets are directed onto the bowl or the bowl surface itself be able. The water exits the distributor through a series of drain holes or slots provided in, for example, a drum.
  • Recent flushing methods employ a swirling water flow pattern in which the inlet water is introduced tangentially along the toilet bowl surface and spirals in the toilet bowl. This differs from the traditional method in which water flows left and right around the inner surface of the toilet bowl to meet at the center front on the user side. Gravity also causes the flush water to lose momentum as it circulates in the toilet bowl and descends in height, making it difficult to achieve full circulation of the flush water in the toilet bowl, so that the flush water goes to the starting point , ie the water distributor, and spills over the water distributor and/or its surroundings to flush these areas of the toilet. The contamination problem of the water distributor and the problem of cleaning the distributor is therefore not solved with these previously known so-called vortex flushers.
  • a further problem is that, particularly in the case of “rimless” toilets, a relatively large drain hole has to be provided in the surface of the toilet bowl for dispensing flushing water. Since this outlet hole is in the rear part of the toilet bowl, it is located exactly in the field of vision of a user of the toilet, which on the one hand is aesthetically very unattractive, since unavoidable dirt usually collects at this outlet hole and on the other hand often leads to the water, which usually runs out under pressure, also because of the dirt, splashes.
  • Another method of flushing a toilet bowl is to use multiple individual water dispensers placed around a top rim of a toilet.
  • Various distributor models are known in this regard, but all of them have a complex geometry and are therefore complicated to manufacture, which is very disadvantageous.
  • at least one of the distributors must be arranged in the front part of the basin, so that the flushing water is flushed backwards.
  • the incoming water which is fed from the back of the toilet, must make a 180° turn to change direction so that the direction of flow of the flushing water is backwards.
  • a sharp bend near the water outlet at the front of the toilet bowl significantly reduces the water pressure, thereby reducing the flushing power available.
  • flushing systems are, for example, in EP 2 604 761 A1 , EP 3 054 061 A1 , EP 1 847 656 B1 , WO 2017/006903 A1 , WO 2016/143 029 A1 , WO 2015/143 391 A1 , EP 3 119 946 A1 , EP 2 233 651 B1 , EP 2 203 608 B1 and the WO 2014/123 494 A1 described.
  • the object of the invention is to solve the above-mentioned problems and to provide a flushing toilet that enables an optimized and hygienic flushing of an inner surface of a toilet bowl and of the siphon.
  • a flushing toilet with a toilet body comprising a toilet bowl and a flushing water outlet, through which flushing water can flow into the toilet body, the flushing water outlet with respect to an imaginary center line, which extends essentially centrally from a front end facing the user during flushing operation of the toilet body to an opposite, substantially central, rear end of the toilet body is arranged asymmetrically.
  • An essential point of the invention is that the flushing water outlet is arranged asymmetrically on the toilet body, so that it is possible to flush water through the flushing water outlet with respect to an imaginary center line, which extends essentially centrally from a front end of the toilet body that faces a user during flushing operation to an opposite end extends rear end of the toilet body to deliver asymmetrically.
  • an important point of the invention is that the asymmetrical arrangement of the flushing water outlet makes it possible to flush the inner surface of the toilet bowl in such a way that part of the flushing water is not, as before, directly from the flushing water outlet in the direction of the siphon, but first via a side wall on the inside of the toilet bowl, so that a circular flow is created which wets the inner surface of the toilet bowl better than with a central attachment of the flushing water outlet on the back of the toilet bowl inside with flushing water and thus cleans it.
  • the asymmetrical arrangement of the flushing water outlet prevents the flushing water outlet from becoming dirty during use of the toilet according to the invention in an extremely advantageous and at the same time extremely simple manner, since the flushing water outlet is no longer arranged directly behind a user in the toilet bowl.
  • the flushing water outlet is arranged according to the invention in a rear lateral area, in particular in a rear lateral corner area, of the toilet bowl, with the flushing water not being discharged downwards but in a substantially horizontal direction tangentially into the toilet bowl. Due to the tangential discharge of the flushing water, the flushing water gyrates in the form of a circular flow in the toilet bowl and flushes a significant part of the inner surface of the toilet bowl before the flushing water then flushes the siphon and thus cleans it.
  • the rear lateral corner area of the toilet bowl is defined as a lateral rear area of the toilet bowl which, depending on the shape of the toilet body, is actually a corner, possibly a rounded corner of the toilet bowl or a rear area of the toilet bowl that is in the toilet bowl Height of the first flushing water outlet opening has a distance from the imaginary center line that is in the range of 70% to 100%, preferably 75% to 100%, and particularly preferably 80% to 100% of a maximum distance of a rear lateral inner surface of the toilet bowl from the imaginary center line located.
  • the maximum distance of a rear lateral inner surface of the toilet bowl from the imaginary center line of the toilet bowl can be different on both sides of the center line.
  • the flush water outlet does not count as the lateral inner surface of the toilet bowl for the purposes of this definition.
  • the rear side wall is the area of the toilet bowl in which a tangent applied to the inner wall of the toilet bowl at the level of the lower boundary of the second flushing water outlet opening encloses an angle of between 90° and 45° with the imaginary center line .
  • the area of a front side wall of the toilet bowl is to be understood analogously within the scope of the invention.
  • the area of a lateral side wall of the toilet bowl is to be understood as the area of the toilet bowl in which a tangent applied to the inner wall of the toilet bowl at the level of the lower boundary of the second flushing water outlet opening encloses an angle between less than 45° and 0° with the imaginary center line, with a Angle of 0° between the tangent with the imaginary center line denotes a parallel course of the tangent and the imaginary center line. In this consideration, only the angles between the applied tangent and the imaginary center line that lie in a range between 0° and 90° are considered within the scope of this invention.
  • the inner periphery of the toilet bowl is to be understood as a line at the level of the lower limit of the second flushing water outlet opening along the inner wall of the toilet bowl, which line extends around the inner wall of the toilet bowl.
  • the flushing water outlet comprises at least one first flushing water outlet opening, through which flushing water can be discharged in a first initial flushing direction, and at least one second flushing water outlet opening, through which flushing water can be discharged in a second initial flushing direction.
  • the flushing water which is conducted along the inner side wall of the toilet bowl, preferably flows from a rear lateral section of the toilet bowl, particularly preferably from a "corner area" of the toilet bowl, first along the lateral wall of the toilet bowl into a front area of the toilet bowl and then then again in the direction of the rear wall of the toilet bowl, where the water discharged from the first flushing water outlet then meets the flushing water discharged from the second flushing water outlet and flows in the direction of the siphon.
  • the water discharged from the flushing water outlet opening is initially not directed towards the lateral inner wall of the toilet bowl, but in the direction of the inner rear wall of the toilet bowl, so that the water discharged from the second flushing water outlet opening is in line with the water discharged from the first flushing water outlet opening and, due to the curved shape of the inside of the toilet bowl, backwards diverted flushing water flows against.
  • a free cross section of the first flushing water outlet opening is larger than a free cross section of the second flushing water outlet opening, so that a first flushing water quantity that is discharged from the first flushing water outlet opening is larger than a second flushing water quantity that is discharged from the second flushing water outlet opening.
  • the water is discharged from the first flushing water outlet opening and/or the second flushing water outlet opening with an initial flushing direction, with the first and/or the second initial flushing direction extending in a substantially horizontal direction ⁇ 0° to 5° with respect to a horizontal and the flushing water thus extending substantially horizontally is delivered.
  • the initial initial flushing direction can be directed slightly upwards in order to counteract a gravitational effect, by which the flushing water is forced to be guided downwards in the direction of the siphon, and in this way to achieve that the first flushing water flow reaches the rear part of the toilet bowl as much as possible reached a high position.
  • the initial initial flushing direction can also point slightly downwards, which can be particularly desirable in the case of “rimless” toilet bowls in order to reliably avoid overspraying of the “rim”.
  • the first and second initial flushing directions are oriented at an angle in the range from 20° to 170°, preferably at an angle in the range from 45° to 140°, and particularly preferably at an angle in the range from 70° to 130°.
  • the first flushing water stream is initially discharged tangentially along a lateral inner side wall of the toilet bowl, and that the flushing water that is discharged through the second flushing water outlet opening is initially and also tangentially along a rear inner side wall of the toilet bowl flows.
  • one or more shoulders and/or a bar or bars can be provided which act as a water guiding device, with the water from the first flushing water outlet opening and/or from the flushing water emerging from the second flushing water outlet opening is guided along a shoulder arranged inside the toilet bowl and/or along a ledge arranged inside the toilet bowl.

  • At least one water guiding device for example in the form of a step, which is designed according to the invention on the inner surface of the toilet bowl can also be formed and defined in that the inner surface of the toilet bowl has a substantially horizontal or, if desired, also, in particular slightly, inclined bulge, which forms the "step", the bulge having a continuously smooth course, when viewed vertically , has two turning points in which an inner contour of the toilet bowl first changes from a concave to a convex shape and then back to a concave shape.
  • the "step" can also be formed in that an inner contour of the toilet bowl that is initially concave when viewed in the vertical direction from top to bottom in an upright flush toilet merges into a convex inner contour of the bowl, which, depending according to the embodiment up to the siphon of the flushing toilet continues to run convexly or conically in a straight line.
  • the water guiding device extends over the inner surface of the toilet bowl at different distances in relation to the respective first flushing water outlet opening and the second flushing water outlet opening, with the water guiding device assigned to the first flushing water outlet opening preferably extending from the first flushing water outlet opening over at least one tenth to halfway or almost completely along the inner periphery of the toilet bowl towards the rear inner side wall of the toilet bowl and wherein the water guiding device associated with the second flush water outlet opening preferably extends from the second flush water outlet opening over substantially one eighth to half the length of the rear inner side wall of the toilet bowl.

  • the respective water guiding device does not directly adjoin a respectively assigned flushing water outlet opening, but rather that the flushing water initially flows "freely” to a certain extent, starting from the respective flushing water outlet opening, before it flows away from the at a certain, predetermined distance from "captured” by the flushing water outlet opening and guided into and around the sanitary bowl at a certain level.
  • a predetermined distance can be in a range from 0.1 cm to 15 cm, preferably in a range from 1 cm to 10 cm and particularly preferably in a range from 1.5 cm to 5 cm. lie.
  • Such an embodiment enables a bifurcal tangential flushing of the toilet bowl in an inventive way, with the distance between the water guiding device and the flushing water outlet opening being used to define how much flushing water is to be routed via the water guiding device and how much flushing water is to be routed directly into areas of the toilet bowl located below the water guiding device and in what type of area Angle the division of the respective flushing water flows should take place.
  • the latter can also be set via an end of the water guiding device that faces the respective flushing water outlet opening.

  • the design of the flushing water distributor as a prefabricated component which is composed of hollow elements that are either subsequently joined together or produced directly in one piece to produce the prefabricated component, offers the decisive inventive advantage that these hollow elements can be produced easily and with very high dimensional accuracy and are also extremely flexible can be combined with each other, so that a fluid channel or several fluid channels can be formed, which are either very simple and largely rectilinear, or very complex and provided with bends and curves, are designed. In this way, even complicated flushing water supply devices can be produced in a simple manner and yet very precisely, which are then built into and integrated into the flushing toilet according to the invention. It should be pointed out that the flushing water distributor used according to the invention can also have more than two flushing water outlet openings.
  • a flush water distributor designed as a prefabricated component is that such a flush water distributor can be arranged very close to the wall of the inner surface of the toilet bowl in the toilet body, so that the flushing liquid emerging from the flushing water outlet openings can be flushed optimally and with almost laminar flow can be directed tangentially to the inside of the toilet bowl, which contributes to a further inventively improved flushing of the flushing toilet according to the invention.
