ABSTRACT:
FIELD OF THE INVENTION
The “Double-Cistern Water-Conserving Sanitary Water Tank” is a device which is made up of two (2) independent tanks or recipients, one inside the other, totally or partially, at the same or different levels and with different capacities; one (1) six-liter tank is used for evacuating solid matter (i.e., Feces), and the other four-liter tank is used for evacuating liquid matter (i.e., Urine), thus allowing the conservation of two (2) liters of water with each flush when the latter tank is used.
This non-provisional use Patent Model consists of a lower six-liter recipient or tank which is semi-oval in shape and has a greater transversal diameter; the lower surface is flat and is the location of the only drain outlet. On this veneer, there is also an opening to permit the water tank to be fastened to the Toilet Bowl. At either end of each side, the lower surface slopes up at an angle, joining with and rising as the side walls. Both recipients touch at the front-to-back diameter. The water-outlet valve of the lower tank is attached laterally to the drain, taking on an elbow-shape, which connects to the drain of the upper tank to form a single outlet, which flows into the Toilet Bowl.
Inside the [larger] lower tank, yet located at a different level, is the four-liter tank meant for the evacuation of liquid matter (i.e., Urine) from the Toilet Bowl.
This inner tank is cylindrical in shape and has a base or lower surface with one opening for the water entry valve and another, which has a small prolongation upwards, forming a lateral pair of slits where the water-output valve is fitted. The lower-front part of this recipient has a notch to allow the water-output valve stopper to be completely lifted. If the base of this recipient has a higher level, this notch is not present, since the stopper of the water-outlet valve can open freely in this case.
On the upper part of the front surface and laterally, there are two (2) openings for the handles which allow the tanks to be emptied independently, as necessary.
It is important to stress that this Double-Cistern Sanitary Water Tank works only with Water-Conserving Toilet Bowls.
INVENTION BACKGROUND
Currently, within the Sanitary Water-Tank/Toilet-Bowl Industry, there are only water tanks having a single tank or recipient, all of which use the same amount or volume of water (12.8 or 6 liters), depending on the model, for evacuating both solid matter (i.e., Feces) or liquids (i.e., Urine) from the Toilet Bowl, which leads to an excessive use of our costly water.
The purpose of this invention is to provide an “Double-Cistern Water-Conserving Sanitary Water Tank” with independent services and different capacities; a six-liter tank for evacuating solid matter (i.e., Feces) and another four-liter tank for evacuating liquids (i.e., Urine) from the Toilet Bowl, thereby allowing the conservation of two (2) liters of water with each flush when the latter tank is used.
This, then, is a Sanitary Water Tank meant to preserve this valuable and scarce natural resource and contributes to the adequate and rationed use of water, promoting ecological awareness and a sensitivity to the wasteful use of water resources.
BRIEF SUMMARY OF THE INVENTION
The purpose of the invention is to supply an “Double-Cistern Water-Conserving Sanitary Water Tank” for the purpose of saving water. The water tank is characterized by actually having two (2) tanks or recipients; a lower one with a six-liter capacity for evacuating solid matter (i.e., Feces) from the Toilet Bowl and another upper tank with a four-liter rapacity for evacuating liquid matter (i.e., Urine) from the same area, as necessary. This allows the independent use of water for each case, permitting a two-liter conservation with each flush when the upper tank is used.
This is a tank with two (2) independent recipients or tanks, one inside the other, totally or partially, at the same level or with one at a slight elevation, which means that the tank lid can be flat or can have two (2) levels. These recipients have different capacities and form a set. Each recipient or tank has independent water intakes and outlets, the latter forming a single drain which leads to the Toilet Bowl. The tank also has two (2) handles, which allow the independent emptying of each recipient or tank, as necessary.
