Definitions

  • the invention relates to the field of flush distributor systems for sanitary articles, in particular for those made of ceramics, for example toilets.
  • toilet bowls are made of ceramic.
  • the bowl itself, as well as the water inlet and flushing distributor for flushing water are cast from ceramic.
  • Ceramic is expensive and a casting process, depending on the design of the object to be cast, for example with various openings and passages, is very complex. Water inlet and flushing manifold areas are also difficult or impossible to access for cleaning or decalcification.
  • Generic purge manifold systems are in DE 10 2006 031 893 A and EP 0 643 177 A disclosed.
  • the invention includes a plastic flush manifold system for use with a sanitary article such as a toilet or urinal.
  • the flush manifold system includes a flush manifold and an attachment line for attaching the flush manifold to a sanitary article.
  • the flushing distributor has an inlet opening, at least one outlet opening arranged at an angle to the inlet opening, and fastening means.
  • a central axis of the inlet port of the purge manifold corresponds to a central axis of the attachment line.
  • the fastening means of the flushing distributor are preferably arranged in the outer area of the inlet opening.
  • the inlet opening is preferably fully accessible.
  • the attachment line also has attachment means, which attachment means of the attachment line correspond to the attachment means of the flushing manifold, for detachably attaching the flushing manifold to the attachment line.
  • the attachment means of the flushing distributor and attachment line are arranged and designed in such a way that they can be removed and permit attachment of the flushing manifold to and from the attachment conduit in a direction perpendicular to the central axis of the attachment conduit.
  • a flushing manifold system in which the flushing manifold and attachment line are detachable from one another allows easy cleaning or replacement of the flushing manifold.
  • the mounting line can be mounted in a plumbing fixture and the flush manifold can be attached to and removed from the mounting tubing as needed, particularly after installation of the plumbing fixture. After removing the flushing distributor, cleaning in the area of the attachment line is also possible. In particular, a decrease
  • Attachment and detachment of the flush manifold in a direction perpendicular to a central axis of the attachment pipe also enables detachable attachment of a flush manifold in a toilet where a ceramic rim makes access to a flush water inlet impossible.
  • the direction perpendicular to the central axis preferably corresponds to a direction downwards or from below in relation to the sanitary item, for example the rim of a toilet bowl.
  • a flushing distributor system made of plastic also makes it easier to produce a sanitary item. In particular, it allows the replacement of ceramic parts that make up a flushing manifold. For example, a mold can be simplified and ceramic can be saved.
  • 'Perpendicular to the central axis' of the fastening line is understood to mean a direction of 90 degrees to the central axis.
  • 'perpendicular to central axis' includes exactly 90 degrees with respect to the direction of removal and attachment of the flushing manifold, as well as a few degrees of deviation from exactly 90 degrees.
  • 'Perpendicular to the central axis' thus also includes directions which deviate by up to 20 degrees from the vertical of the central axis of the fastening line.
  • Fastening means of the scavenging distributor and fastening line are preferably designed in such a way that the scavenging distributor can be removed from or attached to the fastening line by moving in a direction exactly 90 degrees perpendicular to the central axis of the fastening line.

  • An outlet opening is arranged in the flushing distributor system in such a way that, when the flushing distributor system is installed in a sanitary article, it points in the direction of the outlet of the sanitary article or in the direction of a bowl bottom. However, this direction typically points neither exactly vertically downwards nor exactly perpendicularly to the central axis of the fastening system, but rather deviates from the vertical.
  • the attachment means are connected to one another.
  • the attachment means are detached from one another.
  • the attachment means of the flushing distributor and the attachment line are preferably designed in such a way that the attachment means can be connected and released by a relative movement of the flushing distributor and attachment line. Preferably, no tools whatsoever are required for connecting and loosening the fastening means.
  • Connecting and disconnecting of the fastening means can be effected by a linear movement or by a rotational movement or by a combination of a linear and rotational movement.
  • Linear and rotary movements can also be combined.
  • the fastening means can be released initially by a rotational movement, with the flushing distributor then being removed by a linear movement perpendicular to the central axis of the fastening line.
  • the attachment means of the flushing distributor and the attachment line preferably allow the attachment means to be loosened and connected and the flushing distributor to be removed and attached by a linear relative movement, for example an exclusively linear relative movement of the flushing distributor and attachment line.
  • the attachment means of the flushing manifold and attachment line are arranged and configured to allow removal and attachment of the flushing manifold from and to the attachment line by a purely linear movement in the direction perpendicular to the central axis of the attachment line.

  • the attachment conduit has a horseshoe shaped rail and the flushing manifold has a rim projecting around the inlet opening.
  • Alignment and insertion aids can be provided on the flushing distributor and attachment line. These enable easier positioning of the fastening means relative to one another and preferably simplify the fastening process, for example mutual guiding, such as inserting a comb in a groove.
  • the attachment means of the flushing distributor and attachment line can also form a snap lock.
  • the flushing manifold and attachment line can be provided with slightly offset projections that snap into place when the flushing manifold and attachment line are fully connected.
  • a snap fastener can also be configured in other ways, such as an interlocking projection and notch.

  • the stop is preferably formed by the fastening means.
  • a rear side of a fastener forms a stop, while a front side of the fastener corresponds to the fasteners of the flushing manifold.
  • the purge manifold has at least one outlet port. If only a single outlet opening is provided, this preferably not only points in a single direction, but rather allows flushing water to be distributed in several directions.
  • the outlet opening can be designed, for example, as an elongate outlet opening, for example as a curved slit.
  • a single outlet opening preferably enables flushing water to be distributed in a fan shape. Flushing water is thus directed not only in a downward direction, for example, in the direction of the outlet of a sanitary article, but also allows a wide lateral wetting and washing off of an inner wall of the sanitary article.
  • a plurality of outlet openings are provided in the flushing manifold. If there are several outlet openings, these are arranged in different areas of the flushing distributor and preferably point in different directions. Flushing water can thus be directed through the multiple outlet openings into different areas of an inner wall of the sanitary article.
  • the flushing distributor has three outlet openings.
  • a first of the three outlet openings is preferably perpendicular to a second and third outlet opening of the three outlet openings arranged.
  • the second and third outlet openings are preferably in line and allow the flushing water to be distributed in substantially opposite directions.
  • a flushing manifold having three outlet ports is preferably formed as a T-piece, with one side of the T-piece having the inlet port. This is preferably arranged perpendicularly to all the outlet openings, so that a jet of flushing water enters the flushing distributor through the inlet opening and is then prevented from flowing further in a straight line by a wall of the T-piece.
