Definitions

  • Modern toilets or water closets installed in the bathrooms of homes or other residential units are normally designed so that the internal tank collects the feces, which are washed away by water arriving from a container and pushed or carried through a channel inside the bowl towards an external discharge pipe that sends them to the sewer.
  • this internal channel is constructed in an "S" shape so that the water which remains inside of it forms a hydraulic seal, preventing the return of unpleasant odors from the sewer to the bathroom.
  • the discharge channels inside the bowl have a minimum internal diameter of 100 millimeters.
  • a pump draws the water plus the organic residues from the small tank or sump inside the bowl, carrying them through the narrow piping mentioned above to the sewer or the discharge site.
  • the subject of the present invention is a sanitary apparatus with an expulsion-type discharge in which the rinse water from the bowl, together with the solid products to be eliminated, drop into a collection receptacle that forms a single piece with the toilet, or is connected to it, being installed either on the front or on the rear of the toilet; a pump is connected to this recipient to draw away the waste products and waste water, as well as the rinse water, there being no drawing action from the bowl, as the waste products and water are simply flushed into the receptacle by the force of gravity.
  • the form of the aperture through which the waste water and the rinse water are flushed from the bowl into the receptacle is not round, but preferably elliptical or rectangular, with this shape making it possible to maintain within normal levels the overall height of the bowl, and in particular the height of the inside of the bowl, where, following each discharge of the rinse water, a layer of water remains, reaching as far as the lower edge of the flushing aperture.
  • the receptacle for the collection of the flushed water is also cleaned, for all intents and purposes, every time rinse water is supplied to the inside of the bowl, meaning that at the same time as the toilet bowl is being washed, the collection receptacle is also abundantly washed and, thanks to the action of the pump, kept free of residues and odors.
  • Figure 1 shows a vertical cross-section of a toilet improved according to the invention.
  • Figure 2 shows the same toilet viewed from above.
  • the toilet designed according to the invention consists of a bowl 1 whose inside depth 2 is less than that of a normal bowl; the rear of the inside of the bowl is equipped with an aperture for discharge or flushing 3 whose shape is elliptical or rectangular, meaning that its width is greater than its height.
  • the bottom edge of this aperture extends to the upper level 4 set for the layer of water which must remain at the bottom of the bowl 2.
  • An element designed as part of the bowl 1, or as a piece connected to the bowl in such a way as to form a single unit, is the receptacle 5, which, in the drawing, is located behind and underneath the bowl 2, though it could also be placed in front of it; the receptacle 5 receives the water flushed from the bowl through the aperture, consisting of both rinse water and other water (from the sink, etc.), though it is preferable for the other water to be channeled directly into the receptacle 5.
  • This receptacle 5 is connected to a discharge pump 6 located below the bowl 2; the pump 6 is activated manually or automatically. In the latter case, any one of a number of different devices - such as a pressure gauge 7 or a water-level sensor or another appropriate piece of equipment - activates the pump (which can also be equipped with one of the more commonly-used grinding devices), emptying the receptacle of the waste water and the solid waste materials that have arrived either through the aperture 3 or as the result of other discharges from other sanitary and/or hygienic apparatuses.
  • the receptacle 5 is equipped with a closure 8 that makes it possible to inspect the inside.
  • the hollow edge 9 from which the rinse water flows when the discharge is activated.
  • this hollow edge 9 is essentially equipped with one large influx aperture 10 located directly opposite the discharge aperture 3.
  • the entire flow of the rinse water hits the refuse deposited in the inside of the bowl, forcefully dragging it towards the discharge aperture 3.
  • Favorable conditions are created for this action by the presence on the bottom of the bowl of raised ribbing, which is straight in the original design, but can also be curved: the essential point being that the shape help to channel the refuse towards the discharge aperture 3.
  • the inside of the bowl 2 is always left, after each rinsing, with a pre-set quantity of water that protects it against possible soiling by the solid residues deposited and/or discharged inside of it.
  • Yet another advantage is that all odors are rapidly eliminated, while - thanks to the fact that the receptacle 5 for the collection and discharge of the waste is also washed with each flow of rinse water, and is sealed off by the pump with respect to the external discharge conduit - there is no exhalation of odors into the room where the toilet functions.
