PT107792B - DOUBLE RESERVOIR SANITARY CLEANING WITH DUAL HYDRAULIC SUPPLY TO PREVENT WATER WASTE. - Google Patents

Abstract

THE PRESENT INVENTION IS IN THE TECHNICAL DOMAIN OF SANITARY CLEANERS AND INTENDS TO SOLVE THE PROBLEM EXPOSED ABOVE, THROUGH THE REPLACEMENT OF THE VULGAR CLEANLINESS WITH A DOUBLE WATER SUPPLY RESERVOIR. THE DOUBLE RESERVOIR CLEANLINESS CONSISTS OF A LOWER RESERVOIR (R1) AND AN UPPER RESERVOIR (R2). THE RESERVOIR (R2) HAS THE FUNCTION OF RECEIVING THE WATER THAT IS USUALLY WASTE, WHILE THE HOT WATER DOES NOT GET TO THE TAP THAT WE WILL USE. THE WATER FROM THE UPPER RESERVOIR (R2) WILL SUBSTITUTE TO THE LOWER RESERVOIR (R1), WHICH HAS THE FUNCTION OF CLEANING. THE SYSTEM'S OPERATION IS BASED ON THE INSTALLATION OF A FLOAT TAP (9), OUTSIDE THE UPPER RESERVOIR (R2), WHICH OPENS WHENEVER THE LOW WATER LEVEL, IN THE LOWER RESERVOIR (R1). THUS, IT IS OBTAINED TO USE THE WATER, WHICH WAS PREVIOUSLY DIRECTED THROUGH THE WATER INLET (8), TO THE UPPER RESERVOIR (R2).

Description

DESCRIPTION

Double tank sanitary cistern with double hydraulic power.

Technical domain of the invention The present invention is part of the technical domain of sanitary cisterns and intends to solve the problem of wasting water found in the pipe between the hot water source and the faucet where we intend to use the hot water. I propose to solve this problem in a simple way, replacing the current cisterns with a double tank sanitary cistern with double hydraulic supply.

Previous Technique

Currently, in the bathrooms of our homes, every time we open a tap to use hot water, we waste the water, and more serious - drinking water.

In a world of limited resources, it is of utmost importance to use these resources sparingly and rationally, in order to guarantee a dignified life for current and future inhabitants. This is a thought that, fortunately, an increasing number of people are sensitive to today.

Water is one of the most precious things at our disposal, yet every time we use hot water in our bathrooms, we are throwing away several liters of drinking water. Of course, some more conscientious citizens keep this water in containers for later use. We know however that this is not the rule, because it is not practical.

Description of Figures

Figure 1: Lower reservoir (Rl), overflow pipe (4), water outlet control valve (5) for the toilet connection pipe (6).

Figure 2: Upper reservoir (R2), with water inlet (1) from the cold water network, float tap (2) at the bottom of the reservoir (R2) with connection to the float tap (3), immersed in ( Rl), with water inlet (8) from the hot water network, overflow tube (9), button (7) that activates the water outlet valve (5) and float tap (10), immersed in ( R1).

Figure 3: Shows a double-tank toilet flush scheme that contains the following elements:

(1) External tap water inlet from the cold water pipe.

(2) Float tap that closes when the water in (R2) reaches the minimum level for which the tap is regulated. Its function is to prevent the entry of water from the cold water network if there is water in the reservoir (R2).

(3) Float tap immersed in (Rl) which closes when the water in (Rl) reaches the level for which the tap is set.

(4) Overflow tube, from the reservoir (Rl).

(5) Valve for water outlet control.

(6) Connection tube to the toilet.

(7) Valve opening button. This button can be located on the front of (Rl) for practical reasons (eg for built-in tanks in the wall) or for aesthetic reasons.

(8) Water inlet from hot water pipe with external tap. The connection to the hot water supply can be made immediately before the most used hot water tap (or the closest one).

(9) Overflow pipe, from the reservoir (R2).

2/6 (10) Float tap immersed in (Rl) . The tap (10) opens whenever the water level drops to (Rl) and has the function of transferring the water from (R2) to (Rl). It must be set to a level higher than the tap (3).

Operating mode

The reservoir (Rl) has a water inlet from the cold water network controlled by an external safety tap (1) fixed at (R2) and by the float tap (2) located inside the reservoir (R2) that prevents the water inlet from the cold water network, while there is water in (R2) from the hot water network and through the float tap (3) fixed on the outside of (R2) and immersed in (Rl) which closes when the water reaches the regulated level. The overflow tube (4) prevents flooding in the event of a malfunction in the float tap (3) or excess water from the reservoir (R2) and a valve (5) to flush the toilet through the tube (6) . The reservoir (Rl) does not have a lid. It is extended by the reservoir (R2), which may have a transparent bottom (for observation of (Rl)) and a button (7) for opening the valve (5) to which it is connected through a cable or chain. The overflow tube (9) must be used as a passage for this connection. This reservoir (R2) will have the following elements: Water inlet from the hot water network with external tap (8), overflow pipe (9) that drains water into the reservoir (Rl) when the reservoir (R2) fills and it serves as a passage for the valve opening mechanism (5). The reservoir (R2) has, on the outside of its base, a water outlet with a float tap (10) . This buoy will be immersed in (Rl) . It opens whenever the water level drops in (Rl) and allows the transfer of the water existing in (R2) to (Rl) . The reservoir (R2) also has the inlet fixed from the cold water network with an external faucet (1) controlled by the float faucet (2) that opens when there is no water in (R2) and by the float faucet (3) which closes when (Rl) reaches the level set on the float tap (3).

When we need hot water in the bathroom, we open the tap (8) until the hot water reaches the bathroom. We can check it by slightly opening the

3/6 tap before which the inlet (8) was turned on or even placing your hand on the tap (8). At that moment, we close the tap (8) and open the hot water tap that we are going to use. The water we used to waste is in the reservoir (R2) and will pass to the reservoir (Rl) when the water level drops in (Rl) . Of course, water saving works for any hot water faucet we use, but more effectively for the one closest to the point where we connected the faucet (8).

Note that no major works are needed in the bathroom: just a T before the faucet closest to the toilet, install a connecting tube from this to the faucet (8) and connect the faucet (1) where the cistern was previously connected which in the meantime was replaced by the double tank sanitary cistern with double hydraulic power.

Construction and application Double tank cistern with double hydraulic supply can be built in ceramic but also in other materials used in current cisterns, such as plastic, resin or metal. In order to achieve the greatest environmental effect, it is important to have a large audience, which should be aesthetically similar to current cisterns with vertically increased volume, if necessary.

It should be built in two separate elements, fitting (R2) over (Rl) to access the elements outside the reservoir (R2) immersed in the reservoir (Rl). The background of (R2) must be totally or partially transparent, for observation in case of failure.

Float taps must have a tuning mechanism. The tap (10) must be set to a higher level than the tap (3) . The fact that the tap (10) is adjusted to a higher level allows the water in the reservoir (R2) to be used up.

The capacity of (Rl) must be the usual one in our cisterns. If we take a closer look, a part of the volume of our cisterns is wasted, which allows the installation of the double tank cistern with double hydraulic supply, without increasing the amount much.

4/6 volumetry we are used to. In any case, the capacity of (R2) must be adequate to the number of liters that are usually wasted when we use hot water and can be measured for each pipe.

With the measurements I made in a middle-class apartment, I verified that the volume of (R2) should be approximately 7.5 liters in the bathroom farthest from the hot water source. Considering that (Rl) should provide 6 liters of water, it is possible to install in this apartment double tank cisterns with double hydraulic supply, each with the same total volume as the current cisterns.

Optimization of the functioning

The tap (8) must be opened. To check if the water is already hot, we can slightly open the tap closest to the connection. If it is already hot, close the tap (8) and open the tap that we are going to use.

This process can be improved if we are willing to carry out major works: The tap (8) can be connected to the hot water pipe, immediately before each of the hot water taps that supply it.

If, cumulatively, each of these connections has a thermostatic valve to direct the water to the water inlet (8), as long as this does not reach the regulated temperature, the tap (8) does not even need to be operated for the sanitary cistern to function double reservoir with double hydraulic supply, transforming only into a safety tap.

In this way, an optimal achievement is achieved, obtaining the greatest savings in drinking water without having to do more than what we currently do: Open the faucet that we are going to use, wait a little and the first water we get from this faucet is hot water that we need. The cold water that is currently wasted is directed to the double reservoir for later use.

If we are building a new house with several bathrooms or, if it is a hotel, the

5/6 reservoir (R2) must be unique and with adequate capacity, deriving the reservoir outlets (R2) for each one of the reservoirs (Rl) which in this case will have a lid. In each of the tanks (Rl) the float taps (3) and (10) will be applied.
