Definitions

  • the invention relates to a water closet, the seat of which incorporates water jets for personal hygiene purposes - that is: a combination of WC and bidet which is rendered possible by exploiting the seat as a means of supplying the water required by the user to wash his/her private parts.
  • the prior art embraces a type of bidet fitted with jets directed up from the base of the bowl in the direction of the private parts, though this type of design has never tended to replace the traditional type, as it lacks efficiency in terms of operation and does not solve the hygiene problem.
  • Such an appliance can be provided, by combining the functions of the bidet with those of the water closet as shown for example in US-A 4 617 688.
  • the bowl serves simply to support the individual and carry away fouled water, whereas the seat is converted into a plenum chamber serving a set of water jets, and accordingly, hinged in water-tight fashion about the transverses stretches of two supply pipes.
  • the temperature of the jets is controlled by two respective mixers located to the rear of the seat.
  • Water is thus directed from the supply pipes into respective chambers in the seat: a lower chamber at the rear, furnishing a longitudinal and essentially horizontal jet for cleansing of the hindmost parts, and two lateral chambers contained in the two sides of the seat, marginally above the rim of the bowl, that furnish two cross jets projected from a pair of vertical nozzles that extend down below the level of the seat and incorporate upwardly directed deflectors by which the jets are caused to collide marginally above the uppermost plane of the seat, for cleansing the foremost parts.
  • the two nozzles are fitted to the forward ends of the two lateral chambers, which are of dissimilar length, in such a way that the two upwardly angled cross jets are contained within a vertical transverse plane preferably different to that which lies at right angles to the longitudinal axis of the seat.
  • the internal profile of the seat exhibits a bulge directly above the nozzle nearest the front, on which the individual's foot may rest when washed in the colliding cross jets, whilst the internal side opposite is cut away to provide greater freedom of movement to the individual's hand.
  • Advantages afforded by the invention are: greater hygiene; elimination of the bidet, its waste pipe, and related maintenance problems; recovery of space in the bathroom, and the option of utilizing the existing bidet plumbing for other appliances; a more functional bathroom; reduced maintenance; discharge of fouled water facilitated by the larger waste pipe of the WC, and permitted a greater fall than with a bidet; greater convenience for the user, especially if aged or infirm, who need no longer transfer from one appliance to another.
  • 1 denotes the bottom of the WC bowl, from which fouled water flows into a waste trap 2.
  • the seat 3 embodied asymmetrically and functioning as plenum chamber from which water jets are projected, is hinged at rear about the axis A of two respective cylindrical stretches of pipe 4 and 5, transversely disposed, through which water is supplied to the seat 3; the pipe denoted 4 connects with a central, rear chamber 6 created internally of a lower central rear appendage of the seat 3, and the pipe denoted 5 with a composite asymmetrical chamber which occupies the two sides of the seat 3, comprising one short lateral chamber 7, say, on the user's right hand side, and a second, longer lateral chamber 8 on the left.
  • B denotes the axis about which the lid 9 of the seat rotates (figs 2 and 3), mounted by way of a pair of hinge assemblies 10 incorporating relative lugs 11 that project upward from the rear of the seat 3; the lid 9 itself might be embodied in metal, of strength such as to take the weight of a sitting individual, and accordingly, will be provided with an anatomical contour.
  • a transverse hole 15 formed in the lug, coaxial with the hinge axis B, serves to admit a percussion-pin inserted from the outside to the end of disengaging the pin 12 from the socked 14 whenever it becomes necessary to remove the lid 9.
  • 16 and 17 denote water supply inlets, hot and cold respectively, to which two mixers 18 and 19 are connected; the mixers in turn connect with the two hinged stretches of pipe 4 and 5 by way of relative flow pipes 20 and 21 that join with corresponding elbows 22 and 23,24 and 25 denote two straight lengths of pipe inserted rotatably into the two transverse stretches denoted 4 and 5 in combination with water-tight seals 26 and a radial retaining screw 24'.
  • the two stretches 4 and 5 are connected ultimately to the relative chambers 6 and 7-8 in the seat 3 by way of respective elbows 27 and 28.
  • 29 denotes an outlet located centrally in and at the front of the rear lower chamber 6, from which water is projected in a horizontal jet; further jets are projected from the bottom ends of two relatively short pendants 30 and 31 issuing from the underside of the seat 3, the first located at the forward end of the one lateral chamber 7, and the second at the forward end of the remaining lateral chamber 8.
  • the actual nozzles, denoted 30' and 31', are located at the same depth, say, 6 to 8cm from the underside of the seat 3, and occupy a vertical plane C that is displaced from the normal through a given excursion in such a way as to form an angle D with the median longitudinal vertical plane E of the seat, which, in a preferred embodiment, will fall within 45 ° to 90 ° .
  • 32 and 33 denote the respective vertical bores of the nozzles 30 and 31, and 34 and 35 denote relative deflectors the axes of which are raked at a given angle F from the vertical in such a way that the two jets projected from the nozzles 30' and 31' will collide substantially at the intersection of the two vertical planes denoted C and E, and at a height a few centimetres above the upper surface of the seat 3.
  • G denotes the slight, sub-horizontal angle at which the two uppermost surfaces of the sides of the seat 3 slope inward so as to afford comfortable support to the legs, to allow any splashes to drain off, and to permit of resting one foot on the seat; more exactly, a bulge 36 is created for this very purposes in the internal profile of the side which encompasses the larger lateral chamber 8, 37 denotes a recess formed in the internal profile of the seat at the side housing the shorter lateral chamber 7, the purpose of which is to reduce the width of the seat at that particular area from the inside and thus increase the space afforded to the user's hand when reaching under.
  • the housing 38 denotes the water closet bowl, and 39, a housing which projects upward at rear and serves to accommodate the pipework; the housing is clamped to the rear lip 40 of the bowl 38 with bolts 41 the heads of which are bayonetted into the slidable along a matching slot 42 formed in the underside of the housing 39 itself.
  • the user obtains a longitudinal and horizontal jet GO of pressure and temperature to suit, which will be directed at the hindmost private parts.
  • a longitudinal and horizontal jet GO of pressure and temperature to suit, which will be directed at the hindmost private parts.
  • two upwardly directed cross jets GD and GS that collide at a given height within a transverse vertical plane, and where the user is seated, these will be directed at his/her foremost private parts; the same cross jets also serve for a foot bath, in which case the ball or the heel of the foot can be rested comfortably on the bulge 36 with which the side of the seat accomodating the longer lateral chamber 8 is prov ided.
