Definitions

  • the present invention relates to a WC with improved noise characteristics.
  • the sanitary fixture that generates the most noise is the WC.
  • the water released into the WC for flushing usually generates a particularly loud and annoying noise.
  • US2003/088910 which is considered to represent the closest prior art for the invention, describes a flush toilet according to the preamble of claim 1, the flush toilet comprising a toilet body having a bowl for storing wash water as water seal, first means for supplying the toilet body with pressurized wash water and second means for discharging the wash water substantially horizontally along the upper peripheral portion of the inner surface of the bowl to swirl it along the inner surface of the bowl.
  • EP0320372 describes a siphon breaking disconnector for supplying a W.C. pan with water from a pressurized mains supply with a view to flushing said W.C. pan, comprising a first, supply pipe capable of being connected at one end to the mains and opening at the other end into an upper chamber, said chamber communicating, at its lower part, by an axial injector opening with the top part of a cavity provided with a vent situated downstram of the injector opening, said cavity being finally connected for gravity flow to the pan by a second, evacuation pipe, characterized - in that the vent of the cavity consists of the outlet of a spout situated at a first distance from the injector opening, - in that the spout extends externally to the wall of the cavity while sloping slightly upwards with respect to a plane perpendicular to the axis of the injector opening, - and in that the top part of the cavity comprises a tubular skirt surrounding the outlet of the injector opening and extending therefrom over a distance at least
  • the object of the present invention is a WC, the essential characteristics of which are claimed in claim 1, and the preferred and/or secondary characteristics are claimed in claims 2-5.
  • the WC 1 comprises a single-piece ceramic structure 2 defining a bowl 3, a drainage pipe 4 connected to a bottom portion of the bowl 3, and a flushing water supply duct 5 which communicates with the bowl 3 through a single flushing opening 6.
  • the duct is obtained within a rear portion 2a of the structure 2 to be connected to a water supply network.
  • the duct 5 extends along a longitudinal axis X and is defined in sequence by an inlet portion 7 where the connection to the water supply network is implemented and the dimensions of which are standard as regulated by specific directives, by a flowing portion 8, and by an outlet portion 9 in a lateral wall 10 of which the flushing opening 6 is obtained.
  • the outlet portion 9 has a flow-through section that is equal to approximately half of the flow-through section of the flowing portion 8. This means that between the flowing portion 8 and the outlet portion 9 the flow-through section narrows by approximately one half.
  • the outlet portion 9 has a flow-through section with an area ranging from 35 to 65%, more preferably from 45 to 55%, of the area of the flow-through section of the flowing portion 8.
  • the flushing opening 6 is obtained in the lateral wall 10 of the outlet portion 9 and has a flow-through section with an area equal to approximately 35% of the area of the flow-through section of the outlet portion 9.
  • the opening 6 has a flow-through section with an area ranging from 20 to 50%, more preferably from 30 to 40%, of the area of the flow-through section of the outlet portion 9.
  • the outlet portion 9 is defined by the lateral wall 10 parallel to the axis X and by a bottom wall 11 arranged so as to close said outlet portion 9 and which is inclined upwards with respect to the axis X. Owing to the inclined position of the bottom wall 11, the outlet portion 9 extends beyond the flushing opening 6. In this way, the flushing flow speed is reduced which further enhances the efficacy of the present invention.
  • the bowl 3 is delimited by a wall 12 which is defined, following the flow of water as indicated by the arrows in figure 2 , by a first lateral portion 13, by a front portion 14, by a second lateral portion 15 and by a bottom portion 16.
  • the flushing opening 6 is obtained in the bottom portion 16 and faces towards the first lateral portion 13.
  • the lateral wall 12 is rimless and thus ensures better hygiene.
  • a rimless lateral wall guarantees the absence of recesses that are difficult to reach for cleaning and can thus harbour bacteria.
  • the conformation of the front portion 14 of the lateral wall 12 contributes to further improving the correct outflow of the flushing water and thus reducing the amount of noise that is generated.
  • the water that flows out of the flushing opening 6 generates a spiral flow that flows along the entire lateral wall 12.
  • the spiral path of the flow of flushing water thus guarantees that along said path there is no impact between different portions of water with the consequent reduction of noise.
  • the present invention offers the important advantage of being able to guarantee low noise of the flushing water when the WC is flushed, together with high efficiency in cleaning the inside walls of the WC.
