Definitions

  • the invention relates to a flush toilet according to the preamble of claim 1.
  • Flush toilets have been known for some time, with each toilet being equipped with a flush. Flushing a flush toilet has two main functions. On the one hand, the flush should serve to clean the entire inner surface of the toilet bowl and, on the other hand, the flush should remove solids and dirty water from the siphon.
  • the characteristics of a functionally successful flush toilet are to clean a maximum internal surface of the toilet bowl and to remove solids and water from the siphon with maximum flushing power, whereby both the cleaning of the toilet bowl surface and the flushing of the siphon should be carried out without splashing.
  • design features such as a hygienic surface, an easy-to-clean design without dead corners and a quiet flush are also desirable.
  • the size, shape and form of a toilet bowl has a significant influence here, since if the interior surface of the toilet bowl is large and needs to be cleaned, the incoming jet of water is sensibly deflected and in the Drum must be distributed so that the entire drum surface is covered or is exposed to rinsing water.
  • a water distributor is often used, which is arranged between the water inlet and the toilet bowl and divides the water into several partial streams in order to clean the toilet bowl.
  • a water distributor is located in the center of the rear wall of the toilet and is structurally formed as part of the rim, although its physical dimensions may also extend locally downward and/or out of the rim into the toilet.
  • the flushing water is directed around both concave interior sides of the toilet bowl, with some water being directed directly down into the siphon, depending on the water distributor.
  • Such water distributors can also be found in modern "rimless” toilets, with these water distributors being arranged in the middle of the upper back wall of the bowl. Since these "rimless” toilets have no edge, 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 can. The water leaves the distributor through a series of outlet holes or slots, for example provided in a drum.
  • Newer flushing methods utilize a swirling water flow pattern in which the inlet water is introduced tangentially along the toilet bowl surface and spirals within the toilet bowl. This is different from the traditional method, where water flows left and right around the inner surface of the toilet bowl to meet at the front center at the user's end. Gravity further causes the flushing water to lose its momentum as it moves circularly in the toilet bowl and sinks in height, making it difficult to achieve a full circulation of flushing water in the toilet bowl so that the flushing water returns to the starting point , i.e. the water distributor, returns and pours 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 are therefore not solved even with these previously known so-called vortex flushers.
  • Another method of flushing a toilet bowl is to use multiple individual water distributors arranged around an upper edge of a toilet.
  • different distributor models are known, but they all have a complex geometry and therefore complicated production, which is very disadvantageous.
  • at least one of the distributors must be arranged in the front part of the bowl so that the flushing water is directed backwards.
  • the incoming water supplied to the toilet from the rear must make a 180° turn to change direction so that the flow direction of the flush water is backwards.
  • a sharp bend near the water outlet in the front of the toilet bowl significantly reduces the water pressure and in this way reduces the available flushing power.
  • 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 , EP 1 234 921 A1 and the WO 2014/123 494 A1 described.
  • the invention is based on the object of solving the above-mentioned problems and of providing a flushing toilet which enables an optimized and hygienic flushing of the inner surface of a toilet bowl and the siphon.
  • a flush 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 being relative to an imaginary center line which is essentially in the middle of a front end facing a user during flushing operation of the toilet body extends to an opposite, substantially central, rear end of the toilet body, is arranged asymmetrically.
  • 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 to the rear end of the toilet body, asymmetrically.
  • 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 does not come directly from it, as was previously the case the flush water outlet in the direction of the siphon, but first over a side wall on the inside of the toilet bowl, so that a circular flow is created, which wets the inside surface of the toilet bowl with flush water and thus cleans it better than if the flush water outlet is centrally located on the back of the inside of the toilet bowl.
  • the asymmetrical arrangement of the flushing water outlet prevents the flushing water outlet from becoming dirty while using 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 in a rear lateral area, in particular in a rear lateral corner area, of the toilet bowl, wherein the flushing water is not discharged downwards, but tangentially into the toilet bowl in a substantially horizontal direction. Due to the tangential release of the flushing water, the flushing water circulates 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.
  • a rear lateral corner region of the toilet bowl is defined as a lateral rear region of the toilet bowl, which, depending on the shape of the toilet body, actually represents a corner, possibly a rounded corner of the toilet bowl or a rear region of the toilet bowl, which is located in the toilet bowl Height of the first flushing water outlet opening has a distance from the imaginary center line, which 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 lies.
  • 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 is not considered an internal side surface of the toilet bowl for the purposes of this definition.
  • the rear side wall is to be understood as the area of the toilet bowl in which a tangent placed on the inner wall of the toilet bowl at the level of the lower boundary of the second flush water outlet opening forms an angle 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.
  • 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 placed on the inner wall of the toilet bowl at the level of the lower limit of the second flushing water outlet opening encloses an angle between less than 45° and 0° with the imaginary center line, whereby a Angle of 0° between the tangent with the imaginary center line denotes a parallel course of the tangent and the imaginary center line.
