Definitions

  • the present invention relates to a flushing device with a throttle element according to the preamble of claim 1.
  • the in the DE 26 48 072 The arrangement shown has the disadvantage that from the cistern the water shoots at high speed and energy to the throttle, which leads to unfavorable throttling in the area of the usual volume flows.
  • the speed of the water is further increased by the throttling, which is an unfavorable result of the rinse water distribution in the interior of the toilet bowl both in Spülfllosschen toilet bowls as well as toilet bowls with flushing.
  • a flushing device comprises a flushing cistern, a flushing pipe extending from the flushing cistern and having a first pipe section extending along a first central axis, a pipe bend adjoining the first pipe section, and a second pipe section adjoining the pipe bend and running along a second center axis Pipe outlet, and arranged in the purge pipe throttle element for throttling the purge flow in the purge pipe.
  • the second pipe section is designed such that it opens into a connecting pipe, which is guided to a sanitary article, wherein the rinse water is supplied to the sanitary article via the connecting pipe.
  • the throttle element is arranged at a short distance from the geometrical pipe bend end of the pipe bend. In a particularly preferred embodiment, the throttle element is directly, that is directly, arranged at the geometrical pipe bend end in the second pipe section.
  • the arrangement of the throttle element at said distance or directly after the pipe bend has the advantage that the flushing water flowing through the flushing pipe, which is accelerated in the vertical pipe part by gravity, is first braked by the throttle after the pipe bend; and then followed by the pipe bend a typically straight substantially horizontally extending connecting pipe in the sanitary article, which calms the flow of rinse water before shooting into the sanitary article again.
  • the flow can be performed in a controlled manner in the sanitary article, which is advantageous for the distribution of the rinse water in the sanitary article, for example, because splashes and / or overshoot can be avoided from the sanitary article.
  • the throttle element is located at the lowest point in the Spippokastenströmungssystem and as far away from the mouth in the sanitary article. After the throttle element, the rinse water can therefore not accelerate further and caused by the throttle element speed increase can normalize until it enters the sanitary article due to the distant arrangement again.
  • a sanitary article here is a urinal or a rimless toilet bowl or a toilet bowl with flush rim understood.
  • the sanitary article is made of ceramic.
  • the second pipe section in which the throttle element is arranged, lies substantially in the horizontal or with a slight gradient of a few degrees to the horizontal.
  • the connecting tube is substantially horizontal or slightly inclined from a few degrees to the horizontal.
  • the first central axis is preferably substantially perpendicular to the second central axis.
  • the geometric pipe bend end is preferably located in a reference plane, which is oriented at right angles to the second central axis and extends through the end point of a centrally extending through the pipe bend arc.
  • the term geometric pipe bend end is to be understood as being a geometric location on the pipe bend that is not necessarily present by a physical heel or the like.
  • the distance between the throttle element and the geometrical pipe bend end maximally corresponds to the diameter of the second pipe section.
  • the distance is at most 50% of the diameter of the second pipe section.

  • the connecting tube can preferably be inserted into the receptacle and is stored there.
  • a seal is further arranged between receiving and connecting pipe.
  • the throttle element is located between the receptacle for the connecting pipe and the pipe bend.
  • the second pipe section is comparatively long, so that it forms the connecting pipe and that the pipe outlet opens into the sanitary article.
  • the second pipe section has a bearing for the throttle element, wherein the throttle element is insertable into the bearing and wherein the throttle element is preferably rotatably mounted in the bearing. Due to the non-rotatable mounting is achieved that the throttle element is used in the correct position, which may be important depending on the design of the throttle element for the throttle effect.
  • the bearing is preferably before recording between the recording and the pipe bend.
  • the bearing has a stop on which the throttle element is present.
  • a stop for the throttle element can be provided by the connecting tube to be inserted into the receptacle, such that the throttle element is clamped between the stop of the receptacle and the connecting tube.
  • the connecting pipe can be cut to length during installation.
  • the throttle element may be integrally formed on the pipe bend or the second pipe section in an alternative variant.
  • a preferred variant is characterized in that the outer radius of the pipe bend is substantially constant and / or that the Inner radius of the pipe bend is substantially constant.
  • a further preferred variant is characterized in that the outer radius of the pipe bend changes from the geometrical beginning of the pipe bend over the curvature of the pipe bend such that the outer radius of the pipe bend becomes smaller or larger towards the geometric pipe bend end, and that the inner radius of the pipe bend is preferably substantially constant is.

  • the throttle element provides a cross-sectional constriction of the second pipe section, wherein the cross-sectional constriction reduces the cross section of the second pipe section by 5% to 30% or by 10% to 25%.
  • the throttle element has a plurality of throttle webs, which extend radially outward from the second center axis of the second pipe section. As a result, several cake-piece-like segments are formed, through which the water can pass.
  • This type of throttle element has the advantage that the flow is divided into several segments and thus throttled uniformly.
  • the throttle webs are connected to each other in the region of the second central axis and at the opposite end of the throttle webs are connected to each other with a cylindrical ring.
  • the cylindrical ring is then preferably in contact with said bearing point, in which the throttle is mounted.
  • the throttle element has a blocking wall in a region lying below in the installation position, which barrier wall opposes the flushing flow.
  • the barrier wall forms a closed cross-section and provides the flushing water with a corresponding resistance.
  • the barrier wall has the particular advantage that when the trigger Rinsing flow of incoming water from the cistern after the deflection in the pipe bend is dammed up to the height of the barrier wall and only then can continue to flow.
  • the first volume flow peak after the triggering of a purge is provided by the barrier wall, an increased resistance, resulting in a slight stagnation in front of the throttle element.
