Abstract

Water saving system for the shower faucet. It consists of a system that coupled to the outlet of the shower faucet (3) allows, through the actuation unit (5) of the control assembly (4), that the water from said tap is diverted to a reservoir (9) through the duct (7) until it reaches the comfort temperature of 38º - 40º centigrade. When the water has reached that temperature, as can be seen in the digital thermometer (8) whose sensitive termination is attached to the conduit (7), we will rotate the action unit (5) of the command assembly (4) 1/4 back to direct the water, already at the comfort temperature, towards the duct (10) that communicates with the spray nozzle (11) allowing the user to shower.

Description

Water saving system for the tap of the shower.

Object of the invention

The present invention relates to a system which, applied to the shower faucet, achieves water savings Remarkable, easy to install and compatible with systems already existing, both in domestic facilities and in public facilities

The fundamental object of the invention is provide a system that allows significant savings of clean water that is also compatible with the facilities already existing. A deposit can be added to the mentioned system additional to be able to allocate the accumulated water to other uses.

Background of the invention

It's known that every time we need to do use of hot water, it is necessary to waste a certain amount of the same until it reaches 38º - 40ºC, which is the temperature considered as comfort by a large number of users

The present invention aims to save that water that until now was wasted, with the significant advantage of design solutions that can be adapted to current installations and allowing the user, through simple elements control, the choice to start, or not, the system of saving. It also allows the reuse of water saved for any type of use as it is clean and suitable water for consumption.

In reference to the prior art, it should be mentioned that there are different and varied water saving systems on the market, applicable to various fields of use. However, in most cases, these systems are made up of complex installations that often require a large investment due to their high
cost.

It should be noted that the petitioner is unaware of the existence of an economizer system for savings that, destined to specific use of this case, present some technical characteristics, structural and constitutive similar to those advocated by the present invention

Description of the invention

The present invention is a system that, applied to the shower faucet, it allows a significant saving of water, with an adaptation to existing systems and with the possibility of water reuse for other uses.

This system consists of three ducts different associated to a control set, of mechanical type, with one input and two outputs and voluntary drive.

The first of the ducts receives the flow of water from the tap or tap, transporting it to the entry of the command set.

The control assembly, which can be any circuit selector valve of the existing ones on the market, consists of a housing, a shut-off valve and an actuation unit. The housing has an inlet port, two outlet ports, a passage that extends between, and that puts in fluid communication, the inlet port with the outlet ports, and a valve seat arranged at each outlet. The closing mechanism is movably mounted inside the housing, connected, in a solidary way, to the actuation unit, allowing, with a turning movement of about 45º, to choose which output port we want to connect with the input port , leaving, simultaneously, the other exit port closed.

The second of the ducts is connected to one of the output ports of the control assembly, transporting the water flow, from the tap or tap, up to a tank, container or tank of variable capacity and dimensions depending on the specific needs and characteristics of each particular case, where the excess water that we can accumulate is accumulated allocate to other uses. Also, this duct has been joined by sensitive termination of a digital thermometer that allows us know when the flow of water, which passes through said conduction, has reached the comfort temperature of 38º - 40ºC.

The third conduit is connected to the second output port of the control assembly, transporting the flow of water, from the tap or socket, to the nozzle shower head.

This system is preferably designed for the shower faucet but, with the relevant variations, it can adapt to any tap, both for installations domestic as for public facilities.

Description of the drawings

To complete the description that is being performing and in order to help a better understanding of the Features of the invention are accompanied, as an integral part of said description, a set of drawings where, with character Illustrative and not limiting, the following has been represented:

Figure number 1.- Shows a detail in Water saving system perspective attached to the tap shower, where you can see the main elements that It comprises said system.

Figure number 2.- Shows an elevation view of the control unit in which the actuation unit is located in the position that allows the passage of water flow to the housing deposit or, failing that, towards a deposit, container or auxiliary tank.

Figure number 3.- Shows an elevation view of the control unit, in which the unit of action is located in the position that allows the flow of water to pass the shower spray nozzle.

Preferred Embodiment of the Invention

In a preferred embodiment of the invention, represented in Figure number 1, the water supply is made through a cold water conduit (1) coming from the supply network, a hot water pipe coming from the heater or thermos of housing (2), shower faucet (3), a control assembly (4) and an accumulation tank (9).

The user, before entering the shower, must place the actuation unit (5) of the control unit (4) in the position shown in Figure number 2 and operate the tap (3), which may be the existing one in the dwelling before the installation of our system, so that, through the fitting where the conventional shower hose is connected, the duct (6), which can be flexible to adapt to different assemblies, up to the control assembly (4) allowing the water passage If the user keeps the tap in its installation that he already had, he will regulate the tap so that the water goes out to the temperature he wants.

Water then circulates through the duct (7), up to the main deposit of the dwelling, in case have or, failing that, towards a deposit, container or tank (9), of capacity and variable dimensions depending on the needs and specific characteristics of each particular case, which in the new facilities could be placed on the false ceiling or forming part of the formwork of the bathroom walls.

In said conduit (7), which must be copper due to its high coefficient of thermal conductivity, the sensitive termination of a digital thermometer (8), which will indicate at what time the water has reached the comfort temperature of 38º- 40ºC. When the water has reached that temperature the user place the actuation unit (5) of the control unit (4) in the position shown in Figure number 3, so that the water cold, accumulated in the duct (10) of the previous shower, it eject After about 5 seconds, which is the time taken in said maneuver, the actuation unit (5) is replaced in the position shown in Figure number 2, but only the time needed for the user to be inside the screen of shower and close the door of this one.

From this moment you can turn the actuation unit (5) towards the position shown in the Figure number 3 to be able to shower normally, with the exception of that, every time the user soaps the body or head, return the actuation unit (5) to the position shown in Figure number 2, since, in this way, the water returns to exit through the spray nozzle (11) at the same temperature as comfort to which I had graduated initially, with the consequent gain in comfort and time.

Another advantage of this system lies in the fact that the water accumulated in the tank (9) can be use for any use within the home, as it is of clean water and suitable for human consumption.
