Definitions

  • the present invention relates to a toilet flushing system.
  • the present invention relates to a system for flushing the water of a toilet that includes means for propelling the water stored in the interior of a tank to the toilet bowl for the purpose of carrying out a water flushing cycle.
  • Toilets are known that comprise a water cistern or tank where they store the water that is discharged into the toilet bowl when a user actuates the button that gives rise to the toilet water flushing cycle.
  • the water tanks of some of these toilets are disposed elevated at a height with respect to the upper rim of the toilet bowl. This position makes it possible to take advantage of the force of gravity to discharge the water into the toilet bowl.
  • These tanks may be incorporated behind the bathroom wall or installed on top of the toilet bowl, on the rear part of the bowl.
  • the objective of the present invention is to obtain a toilet water flushing system which has the advantage of having a reduced and compact design and also has the advantage of being silent.
  • the present invention provides a toilet flushing system that comprises a tank for storing water and means for propelling the water stored in the interior of said tank to a bowl of the toilet for the purpose of carrying out a water flushing cycle of said toilet, and is characterised in that said propulsion means comprise an air injection device and said tank a dry compartment susceptible of housing said air injection device, said dry compartment being arranged in the interior of the tank such that it is connected to a second compartment of the tank destined for storing the water, wherein the air injected by said injection device is susceptible of propelling the water of the second compartment to the toilet bowl when said injection device operates in the interior of said dry compartment.
  • the present invention provides a toilet that incorporates the flushing system claimed.
  • This toilet may be, for example, a toilet having bidet functions or a standard toilet.
  • the water can be propelled by means of an air injection device housed in a dry compartment of the tank itself.
  • This dry compartment has the peculiarity of being disposed in the interior of the tank such that it is connected to a second compartment of the tank destined for housing the water that must be propelled to the toilet bowl.
  • the water of the tank itself acts as acoustic insulation for the injection device, thereby obtaining a very silent flushing system.
  • the system of the present invention when the injection device is functioning, air is suctioned from the exterior to the interior of the dry compartment and is then injected in the second compartment from the interior of the tank.
  • the system can dispense with connection pipes and occupy a very small space, facilitating the obtainment of very compact and low-cost toilet designs.
  • the dry compartment of the tank comprises an open air injection conduit connected to the second compartment destined for housing or storing the water, said injection device being susceptible of being housed in the interior of said open conduit.
  • the injection device can suction and inject the air from the interior of the tank, through said conduit.
  • the walls of said dry compartment define said air injection conduit.
  • said second compartment destined for storing the toilet flushing water includes a discharge conduit that is associated with the toilet bowl to allow the water to flow out. Therefore, when the device is functioning, the air injected in the dry compartment propels the water stored in the second compartment to the aforementioned conduit to flush the toilet bowl.
  • said water storage tank comprises a water inlet disposed above the water level (h) of the tank and an overflow to allow the water to flow out when the water level inside the tank exceeds a predetermined height.
  • the flushing system comprises means for preventing the water from being discharged through said overflow when the injector device is functioning.
  • said means for preventing the water from being discharged through the tank overflow comprise a section of the second compartment of the tank that includes the overflow and a dividing wall provided with a valve arranged such as to prevent the entry of water in this section of the tank when the injector device is functioning.
  • the aforementioned valve is actuated to seal off or close the inflow of water to the section that includes the overflow, thereby avoiding loss of water.
  • this section of the tank also includes a buoy associated with a sensor that activates the water intake source when the water level inside the reservoir falls below a certain value.
  • the bottom of the water storage tank is disposed below the height defined by the upper rim of the toilet bowl.
  • the water storage tank is integrated in a hidden manner around the toilet bowl. Therefore, a flushing system with an extremely compact design is obtained.
  • the tank may be integrated in the body of the toilet bowl such as to form a single piece with the bowl.
  • This bowl body may be, for example, a conventional porcelain body that defines a space with water storage tank functions in its interior.
  • the tank may be configured as an independent reservoir susceptible of being removable housed in the interior of the toilet bowl body, such that it is integrated in a hidden manner in the body of said bowl.
  • This reservoir may be, for example, a one-piece independent plastic reservoir that can be removable housed in the aforementioned interior space.
  • This plastic tank includes the dry compartment arranged in connection to the aforementioned second water storage compartment.
  • the dry compartment of the tank also includes an open air injection conduit wherein the air injection device can be housed.
  • the air injector device comprises an air blower susceptible of being housed in the interior of the dry compartment of the toilet water storage tank.
  • This blower may be, for example, a blower provided with an electric motor such as, for example, a brushless motor or a blower provided with a mechanical motor.
  • said air blower includes an air injection nozzle susceptible of being oriented towards an air outlet of the dry compartment that is connected to the second compartment destined for housing the water.
  • Figure 1 shows a schematic plan view of a toilet 4 incorporating an embodiment of the flushing system claimed that includes a tank for storing water configured in the manner of an independent reservoir 1 susceptible of being removable housed in an internal space 2 of the body of the bowl 3 of a toilet 4.
  • the water storage tank or reservoir 1 is integrated in a hidden manner in the bowl 3 body, whereupon the bottom of the reservoir 1 is disposed below the height defined by the rim of the toilet 4 seat 3.
  • Figures 2 to 4 show three different sections of the toilet 4 of figure 1 that incorporates the flushing system claimed with an independent water storage reservoir 1.
  • the reservoir 1 has been represented full of water up to the level determined by a buoy 5 that is associated with a level sensor 6 responsible for activating a water intake source 14 when the level falls below the desired height.
  • the reservoir 1 comprises a dry compartment 7 susceptible of housing an air injection device such as, for example, an air blower 8 actuated by an electric motor, for example a brushless motor.
  • the dry compartment 7 is connected to a second compartment 9 of the reservoir 1 through an air injection conduit 10 that is open to the exterior of the reservoir 1.
  • the air blower 8 has been arranged housed in the interior of the injection conduit 10 such as to suction and inject air from the exterior from the dry compartment 7 itself.
  • the walls 7a of the dry compartment itself define the aforementioned injection conduit 10, due to which the outflow of air is carried out in a very simple and efficient manner.
  • the water storage reservoir 1 comprises a water inlet 14 disposed above the water level in the reservoir and an overflow 11 to allow water to flow out when the water level in the tank or reservoir 1 exceeds a predetermined height.
  • a flushing system compliant with European safety standard EN1717 is obtained, since the overflow 11 can eventually allow contaminated water to flow out in case of reflux.
  • the second compartment 9 of the water storage reservoir 1 will include a section 9a with an overflow 11 and a dividing wall 12 provided with a hole 12a with a valve 13 disposed such as to prevent water from entering this section 9a of the reservoir 1 when the blower 8 is functioning.
  • the aforementioned valve 13 is actuated to seal off or close the inflow of water to section 9a, thereby avoiding loss of water through the overflow 11.
  • the air flow "F" injected by the device in this case the blower 8, propels the water stored in the second compartment 9 to a water discharge conduit 15 that discharges the water into the interior of the bowl 3.
  • the valve 13 seals the water inlet hole 12a of the wall 12 of section 9a of the second compartment 9. In this manner, the outflow of water through the overflow 11 is avoided and the water is directed towards the toilet.
  • the level sensor 6 associated with the buoy 5 activates the opening of the water inlet 14 to recover the initial water level of the reservoir 1 (see figure 7 ), such that the toilet 4 is ready for a new flushing cycle.
  • the water of the tank itself acts as acoustic insulation for the injection device housed in the dry compartment 7, due to which a flushing system with a very simple and silent design is obtained.
