Definitions

  • the invention relates to a drain fitting, in particular for showers or bathtubs, with a drain housing that has an interior space that is accessible from an upper inlet opening, with a drain socket protruding from the drain housing, with a partition wall that defines an overflow edge between the interior space and the drain socket, wherein the partition is integrally connected to the drain body as an integral part of the drain body, and with a dip tube inserted into the drain body and removable from the same, forming part of an odor trap.
  • Such a drain fitting is from EP 2 363 543 B1 known.
  • the drain fitting has a housing wall (partition) which is located between the interior space and the drain socket and defines an overflow edge.
  • an opening is formed in the housing wall, which is closed by a removable plug that has a handle element that is accessible from the interior.
  • the plug inserted into the cleaning opening is held and fixed in the closed position by the immersion pipe inserted into the drain housing. It therefore remains securely arranged in the cleaning opening and seals it reliably, even when using a suction bell to clean the drain fitting and the drain line connected to it, in order to prevent a loss of sealing water in the odor trap.
  • the stopper can also be easily removed from the opening after removing the dip tube in order to clean the drain socket and the drain line connected to it using a flexible cleaning spiral or a pressurized water flushing hose if necessary.
  • the invention is therefore based on the object of improving a drain fitting of the type mentioned at the outset with regard to easy cleaning of the same.
  • the drain fitting according to the invention is characterized in that the partition defining an overflow edge can be flexibly deformed in such a way that a section of the overflow edge can be deformed in a trough shape by mechanical pressure. This makes it possible for areas of the drain body located behind the partition wall to be accessible much more easily for cleaning.
  • deformable in the form of a trough means in particular a reversible creation of a trough or trough-shaped depression in the partition wall.
  • the flexible deformability of the partition of the drain fitting according to the invention is not limited to this. Rather, the flexible deformability of the dividing wall also includes a partial or complete turning of the flexibly deformable dividing wall along its overflow edge.
  • the flexibly deformable partition of the drain fitting according to the invention is reversibly deformable.
  • the dividing wall defining an overflow edge is preferably ring-shaped, so that it circumferentially delimits the interior space of the drain housing that is accessible from the upper inlet opening, with the drain housing delimits together with the partition wall an annular outflow channel surrounding the interior space.
  • the flexible deformability of the partition is achieved, for example, by material properties that allow plastic or elastic deformation of the partition at least along a section of the overflow edge.
  • An advantageous embodiment of the drain fitting according to the invention is characterized in that the dividing wall can be flexibly deformed in such a way that a section of the overflow edge can be deformed laterally in a trough shape by mechanical pressure in the direction of the interior of the drain housing.
  • the dividing wall can be flexibly deformed in such a way that a section of the overflow edge can be deformed in a trough shape inwards by mechanical pressure in the direction of a pot-shaped section of the drain housing.
  • a further advantageous embodiment of the drain fitting according to the invention provides that the partition wall can be flexibly deformed in such a way that a section of the overflow edge can be deformed laterally in a trough shape by mechanical pressure in the direction of the drain connector.
  • the dividing wall in this embodiment can be flexibly deformed in such a way that a section of the overflow edge can be deformed in a trough shape laterally outwards by mechanical pressure in the direction of a housing wall of the drain housing or the lower housing part.
  • This configuration allows for easy cleaning of the drain connector and a drain line connected to it by means of a flexible cleaning spiral or a pressurized water flushing hose, and this in contrast to that from FIG EP 2 363 543 B1 known drain fitting without an in cleaning opening formed on the partition and closable by a removable plug.
  • the drain housing is composed of a lower housing part and an upper housing part, the lower housing part together with the partition wall defining a receiving space for receiving sealing water, the lower housing part having a shoulder which extends outwards relative to the receiving space, wherein the shoulder merges into a housing wall that extends upwards in the direction of the upper part of the housing, and wherein the housing wall, the shoulder and the flexibly deformable partition wall define a drain channel that opens into the drain connector.
  • the drain fitting according to the invention no double-walled design of the partition wall defining an overflow edge; rather, the partition can be designed as a single-walled partition in the drain fitting according to the invention, whereby material for the partition can be saved and the dimensions of the drain body can be reduced.
  • a further advantageous embodiment of the drain fitting according to the invention is characterized in that the flexibly deformable partition is made of a soft component, preferably an elastomer or a polyolefin.
  • a soft component preferably an elastomer or a polyolefin.
  • the flexible, deformable dividing wall can be produced reliably and inexpensively as an integral part of the drain body by two-component or multi-component injection molding, with the dividing wall and the part of the drain body directly connected to the dividing wall being made of different plastics.
  • the soft component is, for example, one elastic plastic, preferably rubber-elastic plastic, from the group of crosslinked or thermoplastic plastics.
  • the lower part of the housing and/or the upper part of the housing are made, for example, from a hard component, preferably from thermoplastic material, particularly preferably from polypropylene.
  • the housing part in question can thus be produced cost-effectively in a complex form and with high dimensional stability.
  • the dividing wall has an arcuate wall section which is curved inwards in the direction of the immersion pipe and which faces the drain connection piece.
  • the curved, inwardly curved wall section of the partition wall hardly needs to be deformed for cleaning the drain socket and the drain line connected to it, in order to insert a flexible cleaning spiral or a pressurized water flushing hose from the upper inlet opening of the drain housing into the drain socket after removing the immersion pipe be able.
  • a further advantageous embodiment of the drain fitting according to the invention provides that the arcuate wall section of the dividing wall, which is curved inwards in the direction of the immersion tube, is connected to the dividing wall in a liquid-tight manner via a substantially U-shaped thin area.
  • This configuration enables a simplified, contour-accurate tearing out or cutting out of said wall section of the partition.
  • the thin spot can also be referred to as a tear-off groove.
  • the drainage fitting according to the invention can thus also be used without its own integrated odor trap in drainage systems that have a central floor drain with odor trap, via which all water-discharging Sanitary equipment, in particular shower trays, with the exception of toilets, are drained.
  • the drain fitting according to the invention can also be operated without the dip tube and without the arcuate wall section of the partition that curves inwards towards the dip tube.
  • the drain fitting according to the invention can thus be easily and inexpensively adapted to country-specific requirements. This avoids or standardizes the production of different drain fittings to meet country-specific requirements, as a result of which costs can be reduced, particularly in the production, warehousing and logistics of such drain fittings.
  • the dip pipe has a non-circular cross-sectional profile with a pipe wall section which is associated with the wall section of the partition wall which is curved inward in the direction of the dip pipe, the pipe wall section having an outer profile into which the wall section of the partition wall protrudes or in a form-fitting manner intervenes.

  • the upper housing part 2.2 has a receptacle 3 for a sealing ring 4, which, in the installed state of the drain fitting, surrounds the drain opening in the tub floor and seals against the underside of the shower tray (shower tray) 1.
  • a fastening flange 5 is provided, which rests with a circumferential inclined surface on the upper edge surface of the drain opening of the shower tray, while the sealing ring 4 is pressed against the lower edge surface of the drain opening, and namely by tightening fastening screws 6, which are inserted into through-holes in the mounting flange 5 and screwed into threaded holes provided in the housing upper part 2.2.
  • the Threaded holes are formed, for example, by threaded sleeves cast into the upper housing part 2.2 made of plastic.
  • a cover 7 is attached, which has web-shaped spacers 7.1 and hollow cylindrical spacers 7.2 on its underside for receiving the heads of the mounting screws 6 in a form-fitting manner.

  • the thin spot 14.2 can also be referred to as a tear-off groove or tear-off edge. It makes it easier to cut out or tear out the wall section 14.1 in applications that do not require the drain fitting to function as an odor trap. Such applications exist, for example, in southern Europe, where drainage systems are required that have a central floor drain 21 with an odor trap, through which all water-draining sanitary items, in particular shower trays, except toilets, are drained (cf. 1 ). In such drainage systems with a central odor trap, the drainage fitting according to the invention can also be operated without the immersion tube 19 and without the detachable wall section 14.1 of the partition 14.

  • annular immersion tube collar 19.1 By means of the annular immersion tube collar 19.1, an intermediate space (cavity) 22 can be covered and sealed, which lies at the shower tray floor opening between the drain housing 2 and the fastening flange 5 and in which dirt nests can form without the covering by means of the collar 19.1.
  • the collar 19.1 In order to be able to cover gaps 22 of different heights, depending on the design of the tub floor opening, and thus to avoid accumulations of dirt, the collar 19.1 has a certain height when delivered, which can be adjusted to the height of the gap 22 to be covered by vertical shortening.
  • the collar 19.1 has a large number of annular collar sections 19.11, 19.12 alternating with one another in the vertical direction, which differ from one another by virtue of a different material hardness and/or differentiated by a different collar wall thickness.
  • the different collar sections 19.11, 19.12 of the immersion tube 19 can be realized by two-component or multi-component injection molding.
  • the respective harder collar section or collar section with a smaller wall thickness makes it easier to guide a cutting tool when shortening the collar 19.1 appropriately.
