Definitions

  • the invention relates to a drain fitting for a shower or bathtub, with a housing having an inlet opening and a drain socket, the housing having a drain channel projecting in the shape of an arm, at the end of which the drain socket is arranged, the drain channel forming a odor trap having a wave-shaped, has a channel section defining an overflow edge, the channel section having a convex bottom section, viewed in longitudinal section, which extends at least as far as the overflow edge, and having a seal surrounding the inlet opening, which has a sealing surface designed to rest against the underside of a tub floor.
  • Such a drain fitting for shower trays is from DE 10 2006 053 756 A1 known.
  • the housing of the drain fitting has an interior space that is accessible from the inlet opening and is delimited by boundary walls that are integrally connected to the housing.
  • a water channel is designed as a drainage channel, which first leads upwards from a bottom of the housing and there in a U-shaped arc again a little way down and then horizontally outwards.
  • the housing part that has the water channel is shaped in such a way that the water channel always has a rectangular cross section when viewed in the direction of flow.
  • the water supply is sealed liquid-tight by a separately manufactured front cover. For this purpose, the cover is welded to the housing part that has the water supply.
  • a transition piece is welded to the end of the water channel, which serves to connect the water channel, which has a rectangular cross-section, to a pipe with a circular cross-section.
  • the transition piece represents the actual discharge socket of the housing.
  • the housing of this discharge fitting is therefore made up of three parts.
  • the AT 335 369 B discloses an odor trap for drain installations on shower trays, bathtubs and the like.
  • a vertical inlet connection with a vertical inlet connection, a preferably horizontal outlet connection and an intermediate, extending in the vertical plane, at least partially oblique connecting part with a cross-section whose height is less than its width is.
  • the connecting part consists of two sloping tube parts connected by a vertical leg. The tube parts are connected to each other via a joint.
  • the CN 102720252A discloses a low profile floor drain device.
  • the device comprises a drain housing, a bowl-shaped drain gutter and an in the grate plate used in the drainage channel.
  • the drain channel has a vertical drain socket on its underside, which is inserted into the drain housing.
  • the drain housing has a lateral, wavy drain channel and an immersion tube inserted into the inlet opening of the drain housing.
  • the DE 20 2014 007 392 U1 shows a water drain with a drain pan on the inlet side, a drain line connected to it and a multiple siphon odor trap, which has an internal air area.
  • An air channel is provided in the water drain between the internal air area and an air area at the edge.
  • a pipe socket is inserted into the drain pot, which can be connected to a shower drain channel. Due to the multiple deflection within the siphon, two sealing water reservoirs are formed, which enable a reliable odor trap even with a low construction height.
  • the air duct located in the second bend prevents the formation of negative pressure in the outflow area of the siphon, which under certain circumstances can lead to the odor trap being completely emptied.
  • the object of the invention is to create a drain fitting of the type mentioned at the outset that has a low overall height for floor-level installation of shower trays, can be cleaned comparatively easily and still offers a sufficient sealing water height for a reliable odor trap and a standard-compliant drainage capacity.
  • the drain fitting according to the invention is characterized in that a housing section of the drain channel located above the overflow edge in the functional position of the drain fitting, ie in the assembled state of the drain fitting Sealing surface protrudes upwards, the shortest horizontal distance of the highest point of the overflow edge from the circumferential inner surface of the inlet opening at least 0.9 times, preferably at least 1.1 times, particularly preferably at least 1.2 times the horizontal inner width of the inlet opening, the convex bottom section being designed in such a way that its radius of curvature is greater than half the height of the housing, the housing having a flange carrying the seal, and the overflow edge being at the same level as or higher than the flange carrying the seal or lower than the flange supporting the gasket, where if the lip is lower than the flange, the vertical distance of the lip from the top of the flange is no more than 8mm, preferably no more than 5mm.
  • the inlet opening can also be referred to as the inlet opening.
  • the horizontal inner width of the inlet opening corresponds to the inner diameter of the inlet opening. If, on the other hand, the inlet opening is, for example, essentially semi-cylindrical, oval or elliptical, the horizontal inner width of the inlet opening corresponds to the smallest horizontal inner width of the inlet opening.
  • the shortest horizontal distance of the highest point of the overflow edge of the outlet fitting according to the invention can also be defined in relation to the vertical central axis of the inlet opening.
  • the shortest horizontal distance of the highest point of the overflow edge from the central axis of the essentially circular-cylindrical inlet opening is at least 1.5 times, preferably at least 1.6 times, particularly preferably at least 1.8 times the horizontal inner width or the inner diameter of the inlet opening.
  • the present invention makes use of the fact that bathtubs and shower trays normally have a circumferential edge region at their floor drain opening that protrudes downwards compared to the underside of the tub floor.
  • the invention is based on the basic idea of making ideal use of the available space under the tub floor in terms of height and width for the drain fitting and achieving as few changes in direction as possible in terms of flow in the drain fitting and preferably the smallest possible changes in cross section.
  • the shortest horizontal distance between the highest point of the overflow edge and the circumferential inner surface of the inlet opening is at least 0.9 times, preferably at least 1.1 times, particularly preferably at least 1.2 times the horizontal inner width of the inlet opening .
  • a wave-shaped discharge channel can be achieved which, while ensuring a sufficient or standard-compliant sealing water height, has relatively large deflection radii and therefore no sharp changes in direction. This considerably facilitates the introduction of a cleaning spiral into the wave-shaped discharge channel.
  • the odor trap of the drain fitting according to the invention is designed without a dip tube.
  • no removable, separately manufactured immersion tube is inserted into the drain fitting, which in conventional drain fittings of shower trays forms part of an odor trap. Due to the omission of the dip tube and the fact that the dip tube does not have to be dismantled when cleaning the drain fitting, not only is the effort required for cleaning reduced, but a cost advantage can also be achieved by eliminating the dip tube production.
  • the overflow edge is at the same level as or higher than a flange of the housing that carries the seal, or alternatively, the overflow edge is lower than the flange of the housing that carries the seal, in which case the vertical distance of the overflow edge from the top of the flange supporting the seal is not more than 8 mm, preferably not more than 5 mm. In this way, a further reduction in the overall height of the drain fitting can be achieved while ensuring a sufficient level of sealing water.
  • the wavy channel section has a concave bottom section, viewed in longitudinal section, the arc radius of which is greater than the overall height of the housing according to the invention, makes it particularly easier to insert a cleaning spiral into the wavy outlet channel.
  • the wavy channel section has a convex bottom section, viewed in longitudinal section, which extends at least to the overflow edge and whose arc radius is greater than half the overall height of the housing. This configuration also contributes to particularly easy insertion of a cleaning spiral into the corrugated discharge channel.
  • a further embodiment of the invention provides that the housing of the drain fitting is composed of a lower housing part and an upper housing part, with the lower housing part and the upper housing part being connected to one another in a liquid-tight manner by a circumferential connecting seam, and with the connecting seam being on opposite longitudinal sides of the corrugated channel section of the Drain channel runs.
  • the housing parts can be made of plastic, for example, by injection molding.
  • the circumferential connecting seam between the lower part of the housing and the upper part of the housing is preferably designed as a weld seam.
  • a further embodiment of the invention is that the drain socket is designed for connecting a drain pipe having a circular cross-section and is in one piece with the lower housing part is trained.
  • the housing of the drain fitting according to the invention can thus essentially be composed of only two housing parts.
  • the outflow fitting according to the invention is thus characterized by a very small number of components. This refinement reduces the production costs and the risk of leaking connection points occurring, in particular leaking weld seams.
  • a further advantageous embodiment of the invention is characterized in that the width of the drainage channel, seen in the water drainage direction, decreases between the overflow edge and the drainage socket.
  • the width of the drain channel thus tapers from or after the overflow edge in the direction of the drain socket. In this way, shoulders or edges, which can interfere with the introduction of a cleaning spiral into the discharge nozzle and a pipeline connected to it, are avoided.
  • the wave-shaped discharge channel or channel section preferably has a substantially uniform width (internal width) from its beginning below the inlet opening to the overflow edge.
  • the width of the drainage channel measured orthogonally to the channel base area, increases after the overflow edge in the direction of the drainage connection piece.
  • the inlet opening of the housing is defined by an inner wall of the housing which is essentially circular-cylindrical or has wall sections in the shape of a circular arc, the wall sections in the shape of a circular arc having radially inwardly protruding wall sections Wall sections connected to each other are, in which threaded sleeves are accommodated.
  • the threaded sleeves are used to attach the drain fitting to the floor drain opening of a shower or bathtub.
  • a further advantageous embodiment provides that the wall sections protruding radially inwards are aligned with wall sections protruding radially from the outside of the housing, that is to say from the outside of the housing.
  • the housing has a bottom surface which faces the inlet opening and runs inclined in the direction of the outlet channel.
  • the drain fitting according to the invention is designed in such a way that the distance between the underside of its housing and the sealing surface intended for contact with the underside of a tray floor (in the installed state on the tray floor ) is less than 75 mm, preferably less than 70 mm, particularly preferably less than 60 mm.
  • a preferred embodiment of the invention provides that the housing section of the outflow channel located above the overflow edge projects beyond the sealing surface by at least 10 mm.
  • Yet another embodiment of the invention is characterized in that the sealing surface intended for contact with the underside of a trough floor is provided with an adapter ring which has a vertical thickness of at least 5 mm, preferably at least 10 mm.

  • the drain fittings 1, 1' are suitable for bathtubs and shower tubs which, when installed, offer little space under the tub floor for the arrangement of a drain fitting to be fixed to the floor drain opening. This applies in particular to shower trays that are to be installed flush with the floor.
