Definitions

  • This invention concerns improvements in or relating to ablutionary installations.
  • the invention has particular application to ablutionary installations for showering.
  • a shower installation generally requires a mixing valve or instantaneous water heater to be fitted inside the shower enclosure for supplying temperature controlled water to one or more spray heads in accordance with user selection of the water temperature.
  • the mixing valve or instantaneous water heater take up space in the enclosure, limit style designs and require cold water and hot water or high power electricity supply in the shower enclosure.
  • the spray head commonly comprises a handset mounted on a vertical slide rail such that the spray head can be raised/lowered to suit the height of the person showering, for example an adult or a child.
  • This type of installation typically employs a flexible hose to connect the handset to the mixing valve or instantaneous water heater.
  • the mixing valve is built-in, the water connections to the mixing valve are concealed and the outlet is connected to a separate elbow connector in the enclosure to which the hose is connected.
  • the elbow connector adds to the costs and complexity of the installation.
  • the slide rail slidably supports a bracket having a parking socket in which the handset is detachably mounted to allow the user to remove the handset and direct the spray to wash different parts of the body.
  • the handset is detached from the bracket in this way, there is a risk that the handset may come into contact with wastewater in the shower tray or bath allowing back-siphonage into the shower system. Back-siphonage can be prevented by the use of double check valves in the water supply fittings but this adds to costs.
  • Another approach is to fit a restraining ring to the slide rail and to pass the flexible hose through the ring to stop the handset falling into the shower tray or bath when removed from the bracket. The provision of the restraining ring also adds to costs.
  • the installer has to fit the ring to the slide rail and feed the hose through the ring and it is not unknown for showers to be installed without the ring.
  • the present invention has been made from a consideration of the foregoing problems and disadvantages of the known shower installations.
  • an ablutionary installation for showering comprising a showerhead, a slide rail for supporting the showerhead, the slide rail having an upper, first end and a lower, second end, and a flexible hose for connecting the showerhead to a water supply at the upper, first end of the slide rail.
  • a water control unit such as mixing valve or instantaneous water heater is located outside the shower area.
  • the showerhead can be prevented from coming into contact with waste water when detached by careful selection of the length of the flexible hose and the position of the slide rail.
  • the use of check valves or a separate hose restraining ring to prevent back-siphonage can be avoided with potential cost savings.
  • the user may find that manoeuvring of the handset is easier when the hose is not constrained by a restraining ring.
  • the slide rail extends between a pair of brackets for mounting the slide rail on a support surface such as a wall within the shower area so that the slide rail extends vertically and is spaced from the support surface.
  • the bracket at the upper end of the slide rail includes a coupling member for connecting the water supply to the hose.
  • the coupling member may be configured for connection to the water supply from above (falling supply) or behind (rear entry supply) the upper bracket.
  • the coupling member is concealed within the bracket and is connectable to a supply pipe from a water control unit for supplying temperature controlled water to the handset.
  • the water control unit is located outside the shower area.
  • the water control unit may be located in a room or enclosure with the water control unit arranged above a ceiling panel of the room or enclosure and the supply pipe passed down through the ceiling panel for connection to the coupling member.
  • the water control unit may be located behind the wall and the supply pipe passed through the wall for connection to the coupling member.
  • the water control unit may comprise a mixing valve or instantaneous water heater.
  • the bracket at the lower end of the slide rail includes user operable means for controlling the water control unit.
  • the user operable control means may comprise an interface panel operatively connected to the water control unit.
  • the interface panel may include means for user control of water flow and/or temperature.
  • the control means may comprise manually operable devices such as knobs, levers, buttons or the like.
  • the control means may comprise hands free devices such as proximity sensors.
  • a wire link is provided for transmitting signals between the interface panel and the water control unit.
  • a wireless link is provided and may employ radio, infra-red or other suitable means of transmitting signals.
  • the wire link preferably extends from the interface panel at the lower end of the slide rail to the bracket at the upper end of the slide rail and along the supply pipe to the water control unit.
  • the supply pipe extends vertically through the ceiling, the supply pipe and wire link and are preferably concealed within a cover.
  • an ablutionary installation for showering comprising a showerhead, a slide rail for supporting the shower head, the slide rail extending between an upper bracket and a lower bracket for securing the slide rail to a support surface, one of the brackets being arranged for rear entry of a water supply pipe through the support surface, and a hose connecting the shower head to the water supply pipe.
  • the water connection is made at the upper bracket and the lower bracket includes user operable means for controlling discharge of water from the showerhead.
  • an ablutionary installation for showering comprising a showerhead, a water control unit for supplying water to the showerhead, and user operable means for controlling the water control unit via a wireless link.
  • the wireless link may employ radio, infra-red or any other suitable means for transmitting signals between the user operable means and the control unit.
  • the user operable means may comprise an interface panel within the shower area for operation by the user when showering.
  • the water control unit may comprise a mixing valve or instantaneous water heater located outside the shower enclosure.
  • the interface panel may be incorporated in a slide rail assembly for supporting the showerhead.
  • the slide rail assembly may also incorporate means for connecting a water supply to a flexible hose for delivery of water to the showerhead.
  • the interface panel may be provided at one end of the slide rail assembly and the water connection at the other end.
