Definitions

  • Drain valve for toilet flushing unit restrictor for drain valve, cistern with drain valve and method for its installation
  • the invention relates to a drain valve for a toilet flushing unit with the features of the preamble of claim 1, and a throttle for a drain valve, a cistern with drain valve and a method for its assembly. In recent times, rimless toilet bowls are getting bigger and bigger
  • a rimless toilet bowl has, in contrast to a conventional toilet bowl with flushing edge only a minimal edge directly on the water inlet. This simplifies cleaning, resulting in an improved hygienic condition.
  • the rimless toilet bowl is often preferred from an aesthetic point of view.
  • volume flow of the rinse water so the amount of flushing water supplied per unit time, must be precisely adjusted. If the volume flow is too low, the water supply opposite part of the toilet bowl is not sufficiently flushed. If the volume flow is too high, flushing water can splash beyond the edge of the pool due to the lack of flushing rim. The adjustment of the volume flow is usually made during installation.
  • EP 2 602 391 A1 proposes installing a purge flow restrictor for adjusting the volume flow in the flush water inlet of the toilet bowl.
  • a flushing valve for a toilet flushing unit comprising:
  • Opening and closing the outlet opening is movable
  • a throttle which is arranged downstream of the overflow pipe and designed to adjust the volume flow of flushing water which flows through the drain valve when the drain valve is opened,
  • the throttle comprises an actuating means which is operable in the assembled state of the drain valve for adjusting the throttle.
  • a key idea of the invention is not to provide the element for adjusting the volume flow in the toilet bowl, but to integrate into the drain valve of the cistern. As a result, the actuating means is accessible even in the assembled state of the toilet, so that a setting of the
  • volumetric flow is possible at any time after installation. This will be the
  • the throttle is arranged in the outlet opening of the drain valve. This allows a compact and robust construction of the drain valve. It is further preferred that the volume flow in a range between 1.8 l / s (liters per second) and 2.6 l / s, more preferably between 2.0 l / s and 2.4 l / s is adjustable , This ensures that the drainage valve according to the invention is suitable for use with common rimless toilet bowls and the volume flow of the rinse water can be adjusted so that both an insufficient rinsing effect due to low volume flow and overspray due to excessive volume flow can be avoided.
  • the actuating means is guided through the overflow pipe. This ensures a simple construction and protects the actuating means by guiding in the overflow pipe. It is particularly preferred here that the actuating means projects beyond the overflow pipe. Thus, the actuating means in the installed state of the drain valve is easy to reach.
  • the actuating means is formed by the overflow tube, which is designed to be rotatable about its central axis.
  • a throttle is further specified for use in a drain valve.
  • the throttle according to the invention comprises at least one throttle element, wherein for adjusting the volume flow of the
  • Flow cross-section of the throttle is adjustable by a rotational movement.
  • the throttle element of the throttle according to the invention is connected to the
  • Actuating element of the drain valve in operative connection and thus enables the inventive adjustment of the volume flow by means of
  • the throttle element can be constructed, for example, according to the principle of a diaphragm, wherein by means of the rotational movement, the diaphragm is open or closed.
  • the flow cross-section between a maximum value and 90% of the maximum value can be varied.
  • the throttle comprises two throttle elements, wherein the relative position of the throttle elements by means of the actuating means for Change in the flow cross section is changeable. This form of throttle is structurally simple to implement.
  • a first throttle element is fixedly mounted and a second throttle element movable, in particular
  • the throttle elements are circular and have circular segment-shaped openings. This allows a cost-effective and simple production of the throttle.
  • the throttle elements are circular and have circular segment-shaped openings. This construction allows a
  • stepless adjustment of the flow rate and is technically easy to implement.
  • a cistern is further provided with a drain valve having an outlet, wherein the drain valve is connected to the outlet in the interior of the cistern.
  • This cistern is suitable for use with a rimless toilet bowl, since the volume flow of the rinse water can be adjusted by means of the actuating element, which is easily accessible when the cistern is open.
  • a mounting method for a cistern which comprises the following steps:
  • Actuating means of the drain valve With this mounting method it is achieved that the adjustment of the flushing water volume flow can take place after the cistern and toilet bowl are completely assembled. Thus, the adjustment of the flow rate at any time after installation in a simple manner possible. It does not matter in which order the connection of the cistern, the installation of the drain valve in the cistern and the connection of drain valve and

Since the rod of the actuating element 20 projects out of the overflow pipe 10, this adjustment of the volume flow is easily possible even in the finished assembled state of the toilet. in the
