Definitions

  • the invention relates to a drain valve for a toilet flush unit with the features of the preamble of patent claim 1, a cistern with a drain valve and a method for its assembly.
  • rimless toilet bowls have become increasingly popular. They have many advantages over conventional toilet bowls. In contrast to a conventional toilet bowl with a flushing rim, a rimless toilet bowl only has a minimal rim directly at the water inlet. This simplifies cleaning, which leads to an improved hygienic condition. In addition, the rimless toilet bowl is often preferred from an aesthetic point of view.
  • the volume flow of the flushing water i.e. the amount of flushing water supplied per unit of time
  • the volume flow is too low, the part of the toilet bowl opposite the water inlet will not be flushed sufficiently. If the volume flow is too high, rinsing water can splash over the edge of the pool due to the missing rinse rim.
  • the setting of the volume flow is usually made during assembly.
  • a key idea of the invention is not to provide the element for adjusting the volume flow in the toilet bowl, but rather to integrate it into the drain valve of the cistern.
  • the actuating means is accessible even when the toilet is installed, so that the volume flow can be adjusted at any time after installation. This simplifies the assembly process itself.
  • An adjustment of the volume flow is possible at any time when using a drain valve according to the invention, for example when the toilet bowl is to be changed. This simplifies the assembly and use of rimless toilets.
  • the throttle is arranged in the outlet opening of the drain valve. This enables a compact and robust construction of the drain valve.
  • the volume flow can be set in a range between 1.8 l / s (liters per second) and 2.6 l / s, particularly preferably between 2.0 l / s and 2.4 l / s . This ensures that the drain valve according to the invention is suitable for use with common rimless toilet bowls and that the volume flow of the flushing water can be set in such a way that both an insufficient flushing effect due to a volume flow that is too low and an overspray due to a volume flow that is too high can be avoided.
  • the actuating means is guided through the overflow pipe. This ensures a simple construction and protects the actuating means by being guided in the overflow pipe. It is particularly preferred here that the actuating means protrudes beyond the overflow pipe. The actuating means can thus be easily reached when the drain valve is installed.
  • the actuating means is formed by the overflow pipe, which is designed to be rotatable about its central axis. At this The design eliminates the need to provide a separate actuating means. This simplifies the construction of the drain valve.
  • the throttle can comprise at least one throttle element, the flow cross-section of the throttle being adjustable by a rotary movement in order to adjust the volume flow.
  • the throttle element of the throttle can be in operative connection with the actuating element of the drain valve and thus enable the volume flow to be set by means of the actuating element. This is achieved by varying the flow cross section of the throttle.
  • the throttle element can, for example, be constructed according to the principle of a diaphragm, the diaphragm being able to be opened or closed by means of the rotary movement.
  • the flow cross section can preferably be varied between a maximum value and 90% of the maximum value.
  • the throttle comprises two throttle elements, the relative position of the throttle elements being able to be changed by means of the actuating means for changing the flow cross section.
  • This form of the throttle is easy to implement in terms of construction.
  • a first throttle element is fixedly mounted and a second throttle element is movably, in particular, rotatably mounted.
  • the setting of the volume flow by means of the actuating element can thus be implemented in a particularly simple manner.
  • the throttle elements are circular and have circular segment-shaped openings. This enables inexpensive and simple production of the throttle.
  • the throttle elements are circular and have circular segment-shaped openings. This design allows the volume flow to be continuously adjusted and is technically easy to implement.
  • the outer contour of the throttle elements is adapted to the inner contour of the outlet opening of the drain valve.
  • a throttle designed in this way can easily be installed in the outlet opening of the drain valve and allows the volume flow to be set precisely.
  • a cistern with a drain valve is also specified, which has an outlet, the drain valve being 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 flushing water can be adjusted by means of the actuating element, which is easily accessible when the cistern is open.
  • This assembly method ensures that the flushing water volume flow can be set after the cistern and toilet bowl have been fully assembled. This means that the volume flow can be set easily at any time after installation. It doesn't matter in which order the cistern is connected, the drain valve is installed in the cistern and the drain valve and toilet bowl are connected. The only decisive factor is that the volume flow can be set for correct flushing of the toilet after it has been fully installed.
  • FIG. 1 is a perspective view of a drain valve 1 according to a first embodiment of the invention.
  • the drain valve 1 has a housing 11 which is connected to an end section 13 via a carrier 12.
  • a carrier 12 Of the End section 13 is tubular and has an external thread 13a, by means of which the drain valve 1 can be mounted in a cistern.
  • the end section 13 defines an outlet opening 15 of the drain valve 1, which is closed at its upper end by a seal 14.
  • an overflow pipe 10 is provided which is movably mounted in the housing 11 along its longitudinal axis. At its lower end, the overflow pipe 10 has a protrusion which is connected to a seal 14. If the overflow pipe 10 is raised, the seal 14 is also raised and the outlet opening 15 is opened. Water located in the cistern flows between the supports 12 through the outlet opening 15. If the overflow pipe 10 is lowered, the seal 14 closes the outlet opening 15.
  • actuating means 20 which is designed as a rod which is guided through the overflow pipe 10 and protrudes from it.
  • the rod has a knurl at the upper end.
  • Fig. 2 shows a section of the drain valve 1 from Fig. 1 .
  • the outlet opening 15 has a diameter of 50 millimeters.
  • Fig. 3a shows a perspective view of the lower end of the actuating element 20.
  • the end piece 20b is designed as a ring element which is connected to the rod of the actuating element 20 by radial struts.
  • the end piece 20b of the actuating element is connected to the throttle 30, for example glued, in such a way that a rotary movement of the actuating element 20 is transmitted to the throttle 30 via the end piece 20b.
  • the flow cross section of the throttle 30, and thus the flow cross section of the outlet opening 15, is changed.
  • the rod of the actuating element 20 is rotated on the knurl, and transmit the rotary movement of the actuating element 20 to the throttle 30 connected therewith. Since the rod of the actuating element 20 protrudes from the overflow pipe 10, this setting of the volume flow is possible without any problems even when the toilet is fully assembled.
  • the structure of the throttle 30 and its mode of operation are described in more detail below.
  • FIG. 3b and 3c An exemplary embodiment for the throttle 30 is shown schematically in FIG Figures 3b and 3c shown.
  • the throttle 30 is formed here from a throttle element 31 which consists of a diaphragm structure.
  • the throttle element 31 is shown in three different positions in plan view, in FIG Figure 3c a section through the throttle element 31 is shown in these three positions.
  • the figures show only the flow cross section of the throttle element 31; the outer edge of the throttle element 31, which is in operative connection with the end piece 20b of the actuating element 20, is not shown.
  • the outer diameter of the throttle element 31 corresponds to the inner diameter of the outlet opening 15, so that the throttle 30 is seated flush in the outlet opening 15.
  • FIG Figures 4a to 4c Another embodiment for the throttle 30 is shown in FIG Figures 4a to 4c shown.
  • the throttle 30 according to this exemplary embodiment comprises two throttle elements 32a and 32b, which are essentially identical.
  • Figure 4a shows a plan view of one of the throttle elements 32a.
  • the throttle element 32a has a circular shape and has passage openings in the form of circular segments.
  • the throttle 30 according to this exemplary embodiment is formed from two throttle elements 32a, 32b which lie on top of one another and can be rotated relative to one another.
  • Figure 4b shows a schematic view of the throttle 30 in an exploded view. In the installed state, the lower throttle element 32a is fixedly mounted in the outlet opening 15 and cannot be rotated. At the center of the upper throttle element 32b, the rod of the actuating element 20 is attached (not shown).
  • FIG. 4c illustrates the mode of operation of the throttle 30. If the throttle elements 32a, 32b are congruent on one another, the flow cross-section of the throttle 30 is at a maximum. Now becomes the upper If the throttle element 32b is rotated against the lower throttle element 32a, the flow cross section is reduced, since the circular segment openings of the upper throttle element 32b are partially covered by the segment-shaped struts of the lower throttle element 32a. Thus, the volume flow of the flushing water can be reduced steplessly starting from a maximum value.
  • the dimensions of the circular segment-shaped passage openings can be selected so that the throttle 30 allows a volume flow of 2.4 l / s when the throttle elements 32a, 32b are in congruent position and a volume flow of 2.0 l / s when the segment-shaped struts are not completely covered lets through.
  • the drain valve 1 is mounted in the outlet of a cistern (not shown).
  • a cistern not shown.
  • the complete installation of the toilet system can be carried out, including the connection of the outlet opening 15 to a toilet bowl.
  • a flushing process can now be carried out with the cistern open and the volume flow adjusted by means of the actuating element 20.
  • the actuating element 20 is designed as a rod with a knurl which is guided in the overflow pipe 10. But it is also possible that the actuating element 20 is formed by the overflow pipe 10 itself. The lower end of the overflow pipe 10 is then in operative connection with the throttle 30; the volume flow can be adjusted by rotating the overflow pipe 10 about its longitudinal axis.
  • the end piece 20b of the actuating element 20 is connected to the throttle 30 in the exemplary embodiment described.
  • This connection can be implemented, for example, by gluing the two elements.
  • the throttle 30 can, however, also be designed in one piece with the end piece 20b. The only decisive factor is that the force which is exerted on the actuating means 20 is transmitted to the throttle 30, so that the volume flow can be adjusted by means of the actuating means 20.
