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.
  • 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 2-7.
  • figure 1 is a longitudinal cross-section of a WC according to the present invention.
  • figure la is an enlarged view of a detail of the cross-section shown in figure 1 ;
  • figure lb is a cross-section along the line I-I in figure la;
  • figure 2 is a cross-section along the line II-II in figure 1.
  • 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 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
  • 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 .
