WO2001098595A1 - Sanitary flange with a built-in water-economy siphon - Google Patents

Abstract

The sanitary flange with a built-in water-economy siphon is a device intended to save water whenever the toilet is flushed. It saves up to 46 % water in comparison with the wax ring (typical system used in toilets with a 12 liter tank) and represents an improvement to the turbo flange patent. The improvement roughly involves changing the system located directly on the floor into which the toilet flushes. By reducing the diameter thereof, the air concentrated in the tube is minimized thereby exerting a pressure that will increase the speed, said variables being responsible for water expenditure. The improvement involves lengthening the two inch tube to an optimum length (in the range of 20 to 40 cm) to eliminate the impact of the water in the elbow of the tube of the piping, thereby preventing the speed of the water coming from the flush to be reduced. An additional 19 % water can be saved in comparison with the turbo flange when the toilet is flushed.

Description

 SANITARY FLANGE WITH INTEGRATED ECONOMIZING SIPHONE

Object of the invention.

The present invention relates to a sanitary flange with integrated economizer siphon. The field to which it belongs is that of a sanitary flange. The Sanitary Flange with Integrated Economizer Siphon is a water saver in the discharge of toilets.

Background of the invention.

On the one hand the sanitary flanges arose as a result of the deficiencies that were found in the application of the wax necks when placing them in the lower part of the sanitary, for which it is required to "hit" the hole unlike the flanges that are connected to the sanitary with screws, thus facilitating the installation of the sanitary with the pipe of the pipe.

But without a doubt, the most important thing to mention about our system is the application of the theory of moving fluids, so a brief review of it is given below;

The works of Archimedes, Pascal and Newton contributed greatly to the knowledge of the fluids that are currently available. The fundamental aspects of fluid flow can be analyzed if certain hypotheses and generalizations are established. All moving fluids exhibit a laminar flow, which is the movement of a fluid in which every particle of the same follows the same path (when passing through a particular point) as that followed by the previous particles. As the fluids are incomprehensible and they do not present an appreciable internal reasoning. Under these conditions, predications can be made about the flow rate of the fluid along a pipe or other container. The expense is defined as the volume of fluid that passes through a certain cross section in the unit of time. In order to express this rapidity quantitatively, consider the flow of a liquid to through the tube with an average velocity "v", during a time interval "t", each particle in the stream moves at a distance "vt". The volume "N" flowing through the cross section "A" is obtained by the following expression: N = Avt

In this way, the expense (volume per unit of time) can be calculated as follows:

R = (Avt) / t = va velox cross section A liquid will flow faster through a narrow section of the tube and more slowly through wider sections. This is the principle that makes water flow faster when the current margins come together.

It was observed that most of the bathrooms in Mexico, have a wax neck in the part of the connection of the sanitary with the floor, said wax neck has a diameter of 4 inches, while the sanitary trap (siphon) is only of 2 inches, so that the liquid lost considerably speed in this difference in diameters (fluid theory in motion).

There is a system on the market that replaces the wax neck called "Turbo Flange" having a diameter of 2 inches instead of 4 inches. The problem of the "Turbo Flange" is that the lengthening of the diameter reduction does not continue and therefore the water continues to lose speed when it hits the pipe of the pipe, that is to say in the repodo (where it makes square). The essential difference of the Sanitary Flange with Integrated Economizer Siphon is to extend the reduction of the tube from 2 inches to a length of 20 to 40 cm. In order to disappear the shock of the water with the bend. It is necessary to inform that the tube that lengthens the function of the siphon is of a flexible and totally smooth material in its internal part to avoid any type of friction in the water. The Sanitary Flange with Integrated Economizer Siphon gives additional water savings up to 46% compared to the wax neck and up to 19% compared to the Turbo Flange, approximately. Description.

To complement the description that is being made and in order to help a better understanding of the features of the invention, the present description is attached, as an integral part thereof, to the drawings in which for illustrative and non-limiting purposes, the following has been represented;

Figure 1.- Shows a third dimension view of the sanitary flange with integrated siphon or economizer. Its elements are presented below;

1. 3 inch packing. This package acts as a wax neck and promises that there will be no leakage in it. In the drawing it is put on the outside to express that it is not part of the steel mold, but a piece that is embedded in the plastic piece. 5 2. Inputs for screws one and a half inches long and 5 / inch wide. The screws have the mission of strongly linking the Sanitary Flange with an Integrated Economizer Siphon with the sanitary and only one screw is placed in each of the two entrances.

3. Tube with a diameter of 2 inches and a length of 20 to 40 cm. Main part 0 of our product which, with its elongation, avoids the collision of water with the bend of the pipe.

4. Tube with a diameter of 4 inches with a length of 2.5 cm. It will serve as a connective for the Sanitary Flange with an Economizer Siphon Integrated with the pipe of the pipe. 5

Figure 2.- This figure is the same as Figure 1 with the variant that is a representation in technical drawing and it was decided to add on the sheet to show the lengths of each part. The elements are:

1. Top of the Sanitary Flange with Integrated Economizer Siphon that is immediately attached to the floor, having a length of 7 inches (17.5cm). 2. 4 inch cylinder with 1 inch (2.5cm) length. As mentioned in the part of figure 1 it is responsible for connecting to the pipe tube.

3. 2-inch tube which is the lengthening of the trap (siphon) with length from 8 to 16 inches (20 to 40 cm).

PREFERRED EMBODIMENT OF THE INVENTION (OR BEST METHOD KNOWN TO CARRY OUT THE

INVENTION).

A steel mold is ordered with the design of the Sanitary Flange with Integrated Economizer Siphon that is indispensable for the creation of the product. Sanitary flanges will be manufactured with an economizer siphon integrated with the optimum material through plastic injection into said mold.

The way to use the Sanitary Flange with an Integrated Economizer Siphon will be through the sanitary., Where it will be placed in its lower part., Connecting the sanitary with the pipe of the pipe. It is fastened by two screws which will be located in two holes that the toilet originally has. For baths with tanks of 12, 14 and 16 liters, the float will have to be adjusted to a level of 6.5 liters. Its operation will be by itself in each discharge of the toilet.

Claims

CLAIMS. 1.- A Sanitary Flange that connects the sanitary with the drainage, characterized in that: It has at its lower end a flexible tube that elongates the sanitary trap, which allows the water to increase its flow rate and avoids the collision of water with the bend. 2. A sanitary flange according to the preceding claim characterized in that the diameter of the tube is 2 inches. 3. A sanitary flange according to the preceding claims, characterized by the length of the flexible tube that elongates the sanitary trap between 20 and 40 cm.
