Definitions

  • the present invention relates to the field of plumbing systems and, in particular, it relates to a discharge plumbing for the waste water such as soapy water coming from showers, bathtubs, sinks, but also washing machines, and other uses.
  • waste water for example soapy water, coming from showers, bathtubs, sinks, washing machines, etc.
  • a discharge plumbing having variable length and comprising normally rectilinear portions fitted to curved portions having various curve angles.
  • a discharge plumbing water from a shower tray comprises a discharge drain in hydraulic connection with the shower tray drain hole.
  • the discharge drain is then connected by a discharge duct to the water drainage network.
  • a plumbing guard is normally used made by a gooseneck, or syphon, i.e. a U-shaped duct portion arranged between the discharge drain and the discharge duct. Therefore, it is necessary that between the base of the shower tray and the floor of the room where the shower tray is installed there is a distance that is adapted to arrange a syphon that is high enough to provide a hydraulic head and at the same time to permit a sufficient discharge flow rate of the waste water from the shower tray.
  • a shower tray is fixed at floor level, with its upper surface more or less at a same height of the floor, it is necessary to make deep masonry and plumbing work on which a concrete, or wood top layer on which eventually the tiles and the shower tray are arranged.
  • the above is particularly difficult when the shower tray has to be fixed at floor level where the tiles had already been laid, such as replacement of a bathtub or a previous shower tray.
  • a shower tray with reduced height is disclosed in W02010026088 .
  • the shower tray comprises a discharge drain that, in use, is connected hydraulically by a flexible duct having rectangular cross section to a traditional discharge duct, i.e. with circular cross section.
  • the flexible duct is used to provide a syphon having a reduced height and adapted to be completely contained within the height of the shower tray.
  • the desired shape i.e. a "U-shape"
  • it rests on a base which has the same thickness of the shower tray and is equipped with two protrusions, or projections.
  • the discharge plumbing described in W02010026088 provides that the discharge duct exits from the shower tray with a traditional duct, i.e. with a circular cross section, and therefore it is in any case necessary to provide a top concrete layer with a thickness of at least 80-90 mm, in which the duct has to be embedded. For the same reasons it is not possible to install the discharge duct at division walls having low thickness.
  • connection system for connecting a discharge drain of a shower tray waste water drainage.
  • the system provides in particular a connection element for connecting the discharge tube exiting from the discharge drain having oval shape with the circular discharge duct that leads to the drainage network.
  • the connection element has an oval inlet cross section for the waste water tube of oval shape and an outlet outlet cross section for of the waste water duct towards the drainage network with circular shape.
  • the system provides a syphon member downstream of the water network.
  • This exemplary structure allows making, in particular, a discharge drain equipped with an internal syphon member. Therefore, the discharge drain in addition to a minimum height is capable of ensuring a head of waste water in the drain chamber adapted to cause an obstacle to a bad smell back flow from the drainage network. Furthermore, once exceeded a limit height, i.e. the upper edge of the lowered portion, the discharge drain lets an flow of water from the discharge drain at a speed of about 60-100 litres of water per minute.
  • the discharge mouth has a waste water passage section with shape that is substantially oval, or rectangular.
  • the liquid surface of the waste water that is left in the drain chamber is substantially at a same height of a lateral containing edge of the lowered portion.
  • the wall is, in use, immersed for a predetermined height in the waste water present in the lowered portion. This way, the bad smell coming from the water drainage network is blocked and cannot reach back the drain hole.
  • the portion of the wall that is arranged to be immersed in the waste water can be set between about 3 mm and about 7 mm.
  • the distance of the lower edge of the wall from the surface of the lowered portion can be set between about 2 mm and about 6 mm, for example between 3 mm and about 4 mm.

  • the plastic material can be polymethylmethacrylate.
  • the discharge mouth has a discharge cross section having a larger diameter d1, in particular set between 80 mm and 130 mm, and a lower diameter d2 for example set between about 14 mm and about 20 mm.
  • the larger diameter d1 can be about 124 mm and the lower diameter d2 can be about 16 mm.

  • a foam for example polyurethane foam
  • the discharge drain has a substantially cylindrical symmetry. Therefore, once arranged the discharge drain in the recess, for example of the shower tray, in which it has to be installed it is possible to rotating it about its own vertical axis for orienting the discharge flow towards a predetermined direction. For example, in case of replacement of a bathtub with a shower tray, this particular exemplary embodiment of the discharge drain allows reusing the existing plumbing with high time saving and of low installation costs.
  • the discharge drain can comprise:
  • the secondary lid has an external surface, which in use remains outside.
  • the outer surface may have curvilinear shape for being convex to assist the flow of the waste water from said outer surface towards the discharge surface.
  • the primary lid at a face oriented towards the secondary lid, has support elements adapted to set, in use, said secondary lid at said predetermined distance from said discharge surface.
  • the base body has an inner surface at an angle towards the lowered portion, in order to provide a chute guide and to assist the flow of the waste water towards the lowered portion.
  • the discharge mouth of the base body is connected hydraulically to the drainage network by a discharge duct. It may have at least one portion with substantially rectangular cross section, or oval, which is adapted to couple to said discharge mouth of said base body. More precisely, the portion with substantially rectangular cross section, or oval, extends outwarly, for example out of the shower tray in order to couple hydraulically to the drainage network.
  • the discharge duct also comprises a substantially circular portion that is adapted to couple to the drainage network.
  • the wall can be engageable in a removable way to the primary lid, in particular engageable to the surface of the primary lid that faces towards the base body.

  • the discharge duct is a corrugated duct and is made of flexible material, for example polypropylene, or polyethylene. Therefore, it is possible to fold the discharge duct without changing the passage section for the waste water. This way, it is possible to provide a discharge path for the waste water from the appliance to the water drainage network without the need to use elbow-shaped curved connection fittings, or to different angle curved connection fittings. Furthermore, the use of such a discharge duct reduces remarkably the thickness of a wall, or a concrete top layer, necessary for embedding the discharge duct.
