Definitions

  • the present invention relates to a floor system comprising a porous floor element with an upper surface and a lower surface, through which floor element liquid can pass, and a liquid chamber provided under the floor element, wherein the lower surface of the floor element forms an upper wall of the liquid chamber.
  • the present invention also relates to a sanitary space provided with such a floor system and to a method for cleaning a floor.
  • the floor system according to the present invention can be applied particularly advantageously in sanitary spaces such as for instance a (public) toilet or a washing and/or shower area in for instance a swimming pool or at a camping site. Other applications of the floor system are however not hereby precluded.
  • a known floor system as according to the introduction is a water-permeable washable floor for a public toilet. It is highly important in public toilets that the floor can be cleaned automatically and in a very short time following each use of the toilet.
  • the floor is provided for this purpose with porous granule floor tiles.
  • flushing nozzles Provided along the periphery of the floor and directly above the upper surface of the floor tiles are flushing nozzles through which, making use of a pump, water can be carried onto the upper surface of the floor tiles in order to flush off the floor soiling resulting from a use of the toilet space in which the floor is present. The greater part of the water flows off the upper surface of the floor and is further drained.
  • the passages in the porous floor tiles are moreover found to have a suction action during the flushing with water such that larger dirt components, such as for instance pieces of toilet paper, as it were remain stuck to the upper surface of a floor tile and are not flushed away off the floor together with the water. In addition to contributing toward clogging of the floor, this gives an untidy and unhygienic impression.
  • An object of the present invention is therefore to provide a floor system particularly suitable for applying in a public sanitary facility such as a public toilet, wherein a floor surface can be cleaned better, and which floor system has an increased cleaning interval. Said object is achieved with the floor system according to the present invention, the floor system being characterized in that the liquid chamber is embodied as pressure chamber, wherein the floor system is provided with supply means for forcing liquid upward from below out of the liquid chamber and through the floor element, and with discharge means for discharging from the upper surface liquid forced through the floor element.
  • An advantage of the floor system according to the present invention is that, by applying the supply means which are connected to the liquid chamber functioning as pressure chamber for the purpose of forcing liquid upward from below out of the pressure chamber and through the floor element, the suction action of the floor element is on the one hand not a factor during cleaning of the floor element. Dirt present on the floor is hereby discharged in effective manner.
  • a self-cleaning action of the floor is on the other hand provided by applying the supply means, since not only is dirt prevented from penetrating into the interior of the floor element during cleaning of the floor, and more specifically while residual liquid flows downward from above through the floor element, but dirt which has possibly already found its way into the floor during use of the floor is also driven out of the floor element again through the agency of the liquid forced upward from below through the floor element .
  • a floor is thus provided with a markedly higher level of cleaning after use of the floor and with a considerably longer cleaning interval, and as a result reduced maintenance costs.
  • a further advantage of the floor system according to the present invention is relevant when the floor system is applied in a space in which users are usually barefooted, such as for instance in a shower area in a swimming pool. It is found in practice that there is an increased risk of contracting (fungal) infections in such spaces due to the presence of flakes of dead skin on the floor of the shower space. Because the floor element in the floor system according to the invention can be easily cleaned, also during use, by means of providing liquid passing upward from below through the floor element, a high standard of hygiene can be achieved, thereby reducing the risk of users contracting an infection.
  • the discharge means comprise flushing means for flushing liquid over the upper surface of the floor element.
  • the liquid forced upward from below through the floor element being discharged manually from the upper surface of the floor element, for instance with a water or air spray, a squeegee or the like
  • said flushing means are provided with which the upper surface can be flushed (automatically) with liquid, preferably simultaneously with forcing of liquid upward from below through the floor element, so that liquid including dirt components are effectively removed from the upper surface (after which the still remaining liquid flows away downward through the floor element from above) .
  • the flushing means comprise a flushing nozzle disposed in the vicinity of the upper surface of the floor element, wherein the flushing means are adapted to carry liquid through the flushing nozzle onto the upper surface of the floor element.
  • flushing means comprise a further flushing nozzle disposed above the wall element, wherein the flushing means are adapted to force liquid through the further flushing nozzle to cause liquid to flow downward along the wall element.
  • An advantage of providing such a wall element is that, when the forcing of liquid through the further flushing nozzle is stopped, the liquid remaining on the wall element which does not flow downward along the wall element drains into the wall element itself, thus achieving that the wall element dries again very quickly, at least on its surface.
  • a user thus touches the wall element shortly after cleaning of the floor and wall element, for instance with clothing, this does not result in the clothing getting wet.
  • the floor element lies at an incline.
  • the discharge means preferably comprise a liquid basin for collecting liquid flowing off the upper surface of the floor element, this liquid basin being connected via a feed conduit to the pressure chamber, wherein the supply means comprise a first pump member for forcing liquid upward from below out of the liquid basin via the feed conduit and the liquid chamber and through the floor element.
  • the liquid in the floor system itself can hereby be recirculated so that a considerable saving is realized in the liquid consumption for cleaning the floor element.
  • flushing nozzle prefferably connected via a flushing liquid supply conduit to the liquid basin, wherein the flushing means comprise a second pump member for forcing liquid out of the liquid basin via the flushing liquid supply conduit to the flushing nozzle. Not only is liquid used by the supply means thus recirculated, but also the liquid used by the flushing means.
  • the flushing nozzle comprises a number of separate flushing nozzle units which are provided along a part of a peripheral edge of the floor element and which are adapted to flush liquid over the upper surface of the floor element in the direction of a remaining part of the peripheral edge.
  • the number of separate flushing nozzle units to comprise a number of nozzle units, some of which are directed directly downward at the upper surface of the floor element, and others of which are directed at least substantially parallel to the upper surface. Because some of the nozzle units are directed directly downward, the upper surface is also flushed directly with liquid at the peripheral edge where the respective nozzle unit is present.
  • the nozzle units directed at least substantially parallel to the upper surface drive the liquid present more centrally on the upper surface in efficient manner in the direction of the remaining part of the peripheral wall.
  • These latter nozzle units can also be advantageously utilized for spraying larger dirt components such as paper, leaves and syringes with force off the upper surface, such dirt components being left with some regularity by a user on the floor element particularly in a public toilet, and it being very important that these be removed before use by a subsequent user of the space in which the floor system is present.
  • the pressure chamber is connected via a discharge conduit to the liquid basin, wherein a valve member is provided in the discharge conduit for closing the discharge conduit in a blocking position and leaving the discharge conduit open in a release position. It is thus possible in simple matter to switch between closing of the pressure chamber during forcing of liquid through the floor element by the supply means and leaving open the discharge conduit so that liquid still present in the pressure chamber can easily flow back to the liquid basin.
  • the discharge means comprises a screen member for screening liquid flowing off the surface of the floor element. This advantage applies particularly when said liquid basin is present. A filter action is thus realized by the screen member, whereby possible soiling is not carried back into or onto the floor element.
  • the floor element is constructed from a number of separate mutually adjacent parts, wherein the pressure chamber also comprises a number of chamber parts provided under a separate part of a floor element.
  • the floor system can in this way be more easily applied (arranged) in a relatively large space.
  • the floor element In order to simplify the periodic cleaning of the floor element it is favourable for the floor element to be provided releasably in the floor system.
  • the floor element is a granule floor element which is preferably formed from granule gravel bound together by a synthetic resin.
  • granule floor elements are highly wear-resistant and have a highly suitable porous character. The appearance of at least the upper surface of such a granule floor element is also attractive.
  • Other materials such as sintered metal or for instance a porous plastic are however not precluded as material for the floor element.
  • the present invention also relates to a sanitary space provided with a floor system according to the present invention. Advantages of such a sanitary space correspond to the above stated advantages of the floor system according to the present invention.
