Description
A FLUSH SYSTEM FOR A TOILET TANK
BACKGROUND OF THE INVENTION
A. FIELD OF THE INVENTION
The present invention relates to a flush system for a toilet tank and more specifically to a flush system for a toilet tank which allows to eliminate the use of the flush valve as well as the overflow tube normally included in the typical toilet tanks.
B. DESCRIPTION OF THE PREVIOUS ART
Typical water closets normally include a toilet bowl and a toilet tank comprising: an intake valve connected to a water line and securely coupled to the bottom of the tank, which is operated by a buoyant float or other elements, connected therewith, to open the intake valve after a flush discharge and close it when the tank is at a desired level of water defined by the buoyant float; an overflow tube coupled to an overflow opening at the bottom of the tank, to discharge the water in case that the tank is filled beyond the desired level; a flexible conduit is connected to the filling valve and to the overflow tube, to fill the bowl at a desired level after a flush discharge, providing a water seal at the bowl; and a flush stopper pivotal mounted on a lower end of the overflow tube at a point pin and coupled to a discharge opening at the bottom of the tank and operated by a flush lever connected to said stopper by a cord, chain or the like.
Said flush valves actuated by the flush lever normally represents a point of possible leak mainly because of wearing of the stopper and imperfections caused to the seat of the flushing aperture of the toilet tank, consequently spoiling a great amount of water.
Saving water by avoiding leaks in the water closets and water supply valves, is one of the greatest challenges in the water closet manufacturing industry.
To the applicant knowledge up to date, said flush valve and stopper have been strictly necessary and no system has been proposed to suppress or substitute these components in the toilet tanks.
An independent Applicant's invention, disclosed in a corresponding US. patent application, proposes a flush valve which avoids the use of the stopper, substituting the conventional flush valve by providing a flush tube coupled to the discharge opening of the tank; a hollow cap partially covering said flush tube, comprising a main housing coupled at the bottom wall of the tank and a secondary housing having a less diameter that the main housing, centrally coupled to the top of the main housing in a fluid communication therewith; a washer into the main housing, having a central perforation and a plurality of apertures surrounding said central perforation, to allow passage of water upstream into the main housing; a flexible membrane over the washer, having a central perforation, acting as a check valve to allow the passage of the water upstream into the main housing and avoids the passage of water downstream; said washer and membrane being slide coupled, through their central perforations, to the overflow tube into the main housing and are retained by rods secured to the flush lever, to lift the washer and membrane by the operation thereof, so as to act as a piston into said main housing, lifting the water to the top of the flush tube crating a siphon effect allowing discharging water from the toilet tank, through said flush conduit; and a counterweight over the membrane and washer, to cause falling thereof after the lift lever has been operated.
Said system, although represents a new flush system for the toilet tanks and avoids the use of the stopper avoiding leaks, still includes a flush valve equivalent comprising the above disclose components.
The flush system of the present invention substitutes entirely the flush valve eliminating the use of the stopper and other components thereof, by providing a top opened container having a desired volume of water to be flushed and an intake valve mounted therein, said container is rotary mounted in the toilet tank and is operable by the flush lever to rotate said container, pouring the water to the toilet tank directly flushing it to the bowl. In this way, the use of the overflow tube as well as the flushing valve which is a possible point of leak, are suppressed.
With the flush system for a toilet tank in accordance with the present invention, the flush valve, which is a point of possible leak and water spoiling, as well as the overflow tube to flush water in case of a leak through the intake valve, are no longer necessary because the necessary flush water is contained in the cylinder container and is poured to the toilet tank and directly discharged to the bowl.
SUMMARY OF THE INVENTION
It is therefore a main object of the present invention, to provide a flush system which eliminates the necessity of the conventional flush valve and its corresponding stopper, consequently avoiding a point of possible leaks, as well as the typical overflow tube which is no longer needed.
It is another a main object of the present invention, to provide a flush system of the above disclosed nature, comprising a top opened container having mounted therein an intake valve, which is operable by a flush lever to rotate it pouring the water contained therein to the toilet tank and discharging it directly to the bowl from said toilet tank.
It is also a main object of the present invention, to provide a flush system of the above disclosed nature, which allows to save water by providing said toilet tank with a reduced container including the strictly necessary amount of water for flushing liquids or solids.
These and other objects and advantages of the present invention, will be apparent to the persons skilled in the art, from the following description of the preferred embodiments thereof.
