Definitions

  • the present invention relates to a concealed toilet cistern assembly having a leakage prevention means, and an associated method involving using such a means.
  • the invention concerns leak proofing of wall-embedded toilet cisterns.
  • Concealed or wall-embedded toilet cisterns are well known and their popularity is increasing. By placing the toilet cistern within a wall, only the toilet bowl will occupy space of the room and an improved appearance is provided.
  • European patent application EP2821557 discloses a concealed-type toilet cistern.
  • a water tight shell partly surrounds the cistern in order to prevent a leakage within the bathroom wall.
  • the shell has a large front opening facing towards and beyond the surface of the bathroom wall.
  • the water will not be able to flow to other portions of the wall. Rather, it may only flow into the room within which the toilet is placed.
  • the shell opening in the front is covered with a wall surface. In this wall surface, a relatively small plate
  • the mentioned EP2821557 thus solves the problem of possible leakage damaging the inside of a bathroom wall.
  • That wall surface needs to be removed.
  • Such an operation will often be cumbersome.
  • Such walls often are provided with bathroom tiles, which requires significant effort to retrofit after having performed service on the concealed cistern. In some cases, it may be impossible to re-install such a wall front face with the original appearance.
  • EP2397613 Another publication dealing with the leakage issue of concealed cisterns is EP2397613.
  • an envelope is arranged outside the cistern, so that a possible leak from the cistern is transmitted into the room, beyond the wall surface.
  • the cistern is also arranged within an outer encapsulation, so that a possible leak from the cistern is stopped by the encapsulation to prevent it from reaching the bathroom wall.
  • the encapsulation is a rigid container that has an opening through which the cistern may pass.
  • the opening in the container can have a smaller vertical extension than the vertical extension of the cistern.
  • the cistern should be slightly tilted when moving through the opening.
  • EP2955288 also uses an envelope to control a possible leak from a concealed cistern.
  • the envelope is of an elastic material.
  • An object of the present invention may be to provide a solution, which makes it possible to repair a concealed cistern assembly, without having to damage the wall that conceals the cistern. Another object may be to reduce the risk of a leak entering and damaging the bathroom wall, from a concealed toilet cistern.
  • Another object may be to provide a leak proofing solution for a concealed toilet cistern assembly, which may retain its function even when being affected with a nail or a screw or the like.
  • a concealed toilet cistern assembly comprising a cistern having a cistern outlet, a flush valve inside the cistern and in communication with the cistern outlet, and a flush pipe extending from the cistern outlet.
  • the concealed toilet cistern assembly further comprises a cistern leakage prevention bag within the cistern.
  • the cistern leakage prevention bag has a water inlet.
  • the cistern leakage prevention bag also has a water outlet positioned upstream of a flush pipe and downstream of the flush valve.
  • flushing water When operating the flush valve, flushing water will flow through both the water outlet of the cistern leakage prevention bag and the cistern outlet. Hence, the only path for the water to exit the cistern leakage prevention bag, is through the flush valve, the cistern leakage prevention bag outlet, and the cistern outlet.
  • the flush pipe can be any kind of conduit suitable for guiding flushing water from the cistern, towards a toilet bowl.
  • it can for instance be a rigid pipe or a flexible pipe, like a hose.
  • a water inlet of the cistern assembly will guide water into the cistern leakage prevention bag being installed in the cistern.
  • This is similar to existing cistern assemblies, except that the cistern leakage prevention bag is filled with water instead of the cistern itself (although the cistern leakage prevention bag is indeed arranged within the cistern). Consequently, should for instance a crack or similar damage occur to the cistern wall, the cistern leakage prevention bag will retain the water and prevent a water leak through the cistern wall (i.e. through the damage).
  • the terms downstream and upstream relate to the direction of the flush water upon activation of the flush valve.
  • the cistern leakage prevention bag further comprises an outlet arrangement mounted to the cistern outlet.
  • the outlet arrangement can comprise a cistern outlet connection interface at a downstream end, and a flush valve connection interface at an upstream end.
  • Such embodiments of the first aspect of the invention facilitate for instance replacement of the cistern leakage prevention bag. That is, it makes it easy to install the outlet of the cistern leakage prevention bag between the cistern outlet and the flush valve.
  • the cistern outlet connection interface of the outlet arrangement can typically be in the form of a pipe socket that fits snugly into the cistern outlet.
  • the cistern outlet connection interface of the outlet arrangement may fit within an upper portion of the flush pipe.
  • the interface or connection between the outer face of the outlet arrangement and a bag portion of the cistern leakage prevention bag will be a water tight interface, so that water exiting the cistern leakage prevention bag can only exit through the outlet arrangement, when the cistern leakage prevention bag is in the installed position within the cistern.
  • the cistern leakage prevention bag can advantageously be configured to take an expanded installed mode and a collapsed mode. As will appear from the detailed description below, being able to collapse the cistern leakage prevention bag, makes it possible to transport it through an aperture in a bathroom wall which is smaller than the cross section of the cistern or the cistern leakage prevention bag in the installed mode, along the horizontal plane. This is useful e.g. for
  • the cistern leakage prevention bag can be provided with an attachment means adapted to retain the cistern leakage prevention bag in an installed position within the cistern when the cistern leakage prevention bag is in an installed and water filled state.
  • the cistern leakage prevention bag can comprise a water sensitive sensor on an external face, which is adapted to produce a signal when coming into contact with water.
  • a signal can for instance be a release of a color compound.
  • such a signal can be of any appropriate type.
  • the water sensitive sensor is a component which can be of many different types.
  • the term chip shall herein be broadly construed. In some embodiments, it may merely be for instance a colored strip of paper or other material which is glued onto the external face of the cistern leakage prevention bag.
  • the chip may be an electronic device with a water sensor. Such an electronic chip may have electric signaling for signaling the presence of water, such as an audio signal or wireless radio signal.
  • the said signal may comprise producing a color compound to the water.
  • any water contacting the water sensitive chip will thus become colored by the water sensitive chip, and the colored water will flow through the flush pipe and into the toilet bowl. In this way, the user will be notified of water being present between the cistern leakage prevention bag and the inner face of the cistern wall.
  • a toilet cistern leakage prevention bag comprising a water inlet and a water outlet.
  • the water outlet is provided with an outlet arrangement that comprises a cistern outlet connection interface at a downstream end, and a flush valve connection interface at an upstream end.
  • the cistern leakage prevention bag is configured to take an expanded installed mode and a collapsed mode, as the toilet cistern leakage prevention bag comprises a flexible bag portion.
  • the flexible bag portion when in the expanded installed mode, will follow the internal walls of a toilet cistern. That is, when being filled with water, the bag portion will be laterally supported by the inner walls of the toilet cistern.
  • the outlet arrangement is configured, by means of its cistern outlet connection interface, to be connected to the cistern outlet.
  • the cistern outlet may be in the form of a bore and the cistern outlet connection interface of the outlet arrangement may be in the form of a pipe piece / pipe socket, which can be inserted into the bore.
  • the flush valve connection interface is typically adapted to existing cistern flush valves, so that a flush valve easily can be mounted to the flush valve connection interface.
  • the flexible bag portion of the cistern leakage prevention bag can be attached to a, pipe-like portion (e.g. being a short piece of pipe) of the outlet arrangement.
  • a water leak between the interface between the outlet arrangement and the rest of the cistern leakage prevention bag (the flexible bag portion), could make water trickle into flush pipe leading from the cistern.
  • the cistern leakage prevention bag can comprise an attachment means adapted to retain the cistern leakage prevention bag in the expanded, installed position within the cistern, when the cistern leakage prevention bag is in a water filled state.
  • the cistern leakage prevention bag can comprise a water sensitive sensor on an external face, which is configured to produce a signal when coming into contact with water.
  • a method of preventing leakage from a cistern of a concealed toilet cistern assembly, wherein the cistern is embedded within a wall involves the following steps: a) removing an operating panel installed in a wall aperture of said wall;

Since the leak occurs within the wall, one may not detect the leak sufficiently early to avoid severe damage to the wall and possibly to the building structure. Such a leak may for instance be due to a manufacturing defect, or a damage taken place after installation (e.g. someone drilling into or hammering a nail into the opposite side of the wall and hitting the cistern 3).
