Description

REGADERA CON SISTEMA PARA AHORRO DE AGUA WATERING WITH WATER SAVING SYSTEM
Campo de Ia Invención.Field of the Invention.
La invención se relaciona con dispositivos ahorradores de agua del tipo que se emplean en el área de Ia ducha y más específicamente se refiere a una regadera que incorpora un novedoso sistema para ahorro de agua gracias al cual el agua que recién sale de una regadera convencional, cuando se abre Ia llave del agua caliente, en lugar de que se desperdicie, yéndose hacia el resumidero sin haberse aprovechado, se deriva hacia un tanque de almacenamiento dando tiempo suficiente a que empiece a salir el agua caliente para mezclarse con ella y que de Ia regadera salga el agua a Ia temperatura deseada por el usuario.The invention relates to water-saving devices of the type that are used in the area of the shower and more specifically it relates to a shower that incorporates a new system for saving water thanks to which the water that just leaves a conventional shower, when the hot water tap is opened, instead of being wasted, going towards the drain without having taken advantage of it, it is drifted into a storage tank giving enough time for hot water to start flowing out to mix with it and that of Ia water can drain the water at the temperature desired by the user.
Antecedentes de Ia Invención. Poniendo a Ia regadera en Ia dimensión que Ie corresponde, como un objeto de uso cotidiano y masivo en casi todos los rincones del mundo, se Ie debe reconocer su importancia en Ia sociedad, no solo por el servicio que nos proporciona al ayudar a nuestra higiene y comodidad sino también como un foco de alarma ecológica dada su estrecha relación con el consumo del agua y el desperdicio de ésta por ciertos malos hábitos generalizados en Ia población. De esta manera, con el modelo de regadera de Ia presente invención se pretende contribuir al ahorro de este vital líquido, en cada hogar y todos los días, ya que en Ia actualidad las regaderas convencionales no cuentan con ningún sistema de ahorro y por consiguiente el consumo del agua esta sujeto a las costumbres y usos particulares de cada persona que cuenta con una.Background of the Invention. Putting the shower in the dimension that corresponds to it, as an object of daily and massive use in almost every corner of the world, its importance in society must be recognized, not only by the service it provides to help our hygiene and comfort but also as a focus of ecological alarm given its close relationship with water consumption and its waste due to certain generalized bad habits in the population. Thus, with the shower model of the present invention it is intended to contribute to the saving of this vital liquid, in each home and every day, since currently conventional showers do not have any saving system and therefore the Water consumption is subject to the customs and particular uses of each person who has one.
El principal problema a enfrentar es el desperdicio de agua en el momento de bañarnos, el cual resulta de Ia costumbre popular de abrir las llaves que controlan el flujo de agua hacia Ia zona de Ia ducha y dejar correr el agua de Ia regadera porque no sale a Ia temperatura deseada para empezar a bañamos con Io que dicho líquido se desperdicia porque se vierte directamente hacia el drenaje sin haber sido aprovechado. Es bien sabido por todos que Ia "primera" agua que sale de Ia regadera normalmente no tiene Ia temperatura que preferimos para bañarnos y de ahí precisamente que Ia desperdiciamos dejándola fluir hasta que salga a Ia temperatura que deseamos. En un intento por atacar el problema de escasez del agua y su aprovechamiento racional, se han propuesto diversos y muy variados sistemas para el ahorro de agua, de entre los que se encuentran algunos especialmente diseñados para reaprovechar el agua previamente utilizada en Ia ducha para Ia descarga del inodoro o retrete. Un ejemplo de ese sistema se describe en Ia patente norteamericana No. 3,594,825 de Reid, en Ia que se ilustra un sistema de abastecimiento de agua para una ducha y lavabo, incorporado a un vehículo, el cual consiste de un tanque o depósito debajo del área de Ia regadera para recolectar el agua utilizada durante el baño o ducha de una persona y derivarla hacia el tanque de agua del inodoro. Aunque este sistema cumple con su propósito de reutilizar el agua y con ello contribuir al ahorro de agua, dista mucho de ser parecido al de Ia presente invención.The main problem to face is the waste of water at the time of bathing, which results from the popular custom of opening the keys that control the flow of water to the shower area and letting the water run from the shower because it does not come out at the desired temperature to start bathing so that said liquid is wasted because it is poured directly into the drain without having been used. It is well known by all that the "first" water that comes out of the shower normally does not have the temperature that we prefer to bathe and hence precisely that we waste it by letting it flow until it leaves at the temperature we want. In an attempt to attack the problem of water scarcity and its rational use, various and very varied systems have been proposed for water saving, among which are some specially designed to reuse the water previously used in the shower for Ia toilet discharge or toilet. An example of this system is described in Reid's US Patent No. 3,594,825, which illustrates a water supply system for a shower and washbasin, incorporated into a vehicle, which consists of a tank or tank below the area of the shower to collect the water used during a person's bath or shower and divert it to the toilet water tank. Although this system fulfills its purpose of reusing water and thereby contributing to water saving, it is far from being similar to that of the present invention.
Otro sistema para ahorro de agua, similar en concepto al anteriormente citado, se describe en Ia patente norteamericana No. 5,341 ,529 de Serrano, en Ia cual se propone un sistema para reutilizar el agua jabonosa que resulta de una ducha recolectándola en Ia zona de Ia regadera y enviándola hasta un tanque complementario que esta dispuesto sobre el tanque de agua del inodoro, y en comunicación de flujo con éste, para abastecer a éste para Ia descarga. El sistema patentado cuenta con un dispositivo de bombeo para hacer llegar el agua utilizada en Ia regadera hasta el tanque complementario. Sin embargo, aunque este sistema ahorrador cumple con su cometido no presenta, técnicamente hablando, semejanza alguna con el de Ia presente invención.Another system for saving water, similar in concept to the aforementioned, is described in US Patent No. 5,341, 529 of Serrano, in which it is proposed a system to reuse soapy water that results from a shower collecting it in the area of The shower and sending it to a complementary tank that is arranged on the toilet water tank, and in flow communication with it, to supply it for the discharge. The patented system has a pumping device to deliver the water used in the shower to the complementary tank. However, although this saving system fulfills its mission, it does not present, technically speaking, any resemblance to that of the present invention.
A diferencia de las regaderas convencionales y de los sistemas de ahorro del arte previo, Ia regadera de Ia presente invención presenta elementos innovadores que en combinación materializan un novedoso y práctico sistema de ahorro de agua.Unlike conventional showers and prior art saving systems, the shower of the present invention presents innovative elements that in combination materialize a novel and practical water saving system.

El campo técnico de Ia presente invención es en el de ahorro de recursos naturales, particularmente en el ahorro de una cantidad importante del agua que se desperdicia cuando una persona se baña. Las regaderas convencionales consisten sólo en un tubo que lleva agua a una salida, con Ia forma necesaria para proporcionar un ángulo de caída determinado dependiendo de Ia cebolla que se utilice para distribuir el flujo uniformemente, Ia mezcla de agua fría con agua caliente se hace únicamente con Ia regulación de los flujos mediante las llaves de paso que se encuentran previamente instaladas en los baños con regadera. Con referencia a los dibujos de Ia invención que se acompañan, Ia regadera (100) con sistema de ahorro de agua el sistema se caracteriza porque consiste de un conjunto de elementos integrados a Ia tubería que descarga el agua en una regadera convencional. El sistema incluye un dispositivo desviador (10) del flujo de agua que se acopla a Ia conexión (8) de Ia tubería de agua en un punto adyacente o inmediato al muro (5), y que esta diseñado con una cámara de distribución (25), por medio de Ia cual el agua se direcciona en dos trayectorias de flujo predeterminadas, una a Ia vez, para Io cual cuenta con una palanca (15) que se inserta en un conducto del dispositivo para moverse rectilíneamente a Io largo del mismo de una primera posición en Ia que queda bloqueando el paso del agua hacia Ia regadera (Fig. 5), y Ia deriva hacia el tanque a través del orificio (19) angulado de Ia palanca, a una segunda posición en Ia que deja desbloqueado (Fig. 6) el paso del agua por Ia tubería (80) que va hacia Ia regadera (90), cuando el orificio (18) de Ia palanca queda en registro con el conducto de Ia tubería (80). La palanca (15) es una pieza tubular alargada en cuya sección delantera (Ia que se introduce en el dispositivo desviador) están los orificios pasantes (18, 19) que sirven como elementos de paso para dirigir el flujo de agua como se indica antes, según Ia posición en Ia que se encuentre dicha palanca. El sistema (100) incluye además un tanque (20) de almacenamiento de agua dispuesto debajo del nivel de Ia tubería de agua y sujeto a ésta por algún medio adecuado, dicho tanque esta previsto para contener el agua fría que, cuando Ia palanca (15) asociada al dispositivo desviador (10) se encuentra en Ia primera posición, se deriva hacia dicho tanque a través de un conducto (12) de derivación del dispositivo (10) y una manguera (17) conectada al mismo, Ia cual se fija a un medio de entrada (22) provisto en Ia superficie superior del tanque. El tanque (20) es de cualquier capacidad apropiada y posee además un sistema detector de nivel del agua que se vierte en el tanque, que consiste en un flotador (30) y un interruptor (32) de alarma que es activado por el flotador cuando éste ha alcanzado Ia altura o nivel máximo del agua que se ha previsto contener en el tanque. Como resultado de Ia activación del interruptor (32) se activará una alarma audible (40) que por medio de sonidos intermitentes avisará al usuario de que ya puede introducirse para bañarse. Un dispositivo (50) tipo venturi esta colocado en Ia trayectoria de flujo del agua, en una posición entre el dispositivo desviador (10) y Ia regadera (90) de manera que influye en Ia presión del flujo y velocidad del agua que pasa a través de dicho dispositivo. Además, el dispositivo tipo venturi (50) tiene un conducto (52) de reingreso de agua que se conecta en comunicación de flujo de agua con el interior del tanque (20) por medio de una manguera (24) de manera que cuando el agua fluye a través del venturi (50), cuando Ia palanca se encuentra en Ia segunda posición antes referida, se produce un efecto de vacío en Ia recámara de vacío (55) de dicho dispositivo (50) que hace que el agua contenida en el tanque sea succionada para que reingrese (Fig. 9) a Ia tubería (80) que conduce el agua hacia Ia regadera (90), mezclándose con el agua caliente que proviene del calentador de agua convencional (no mostrado)The technical field of the present invention is that of saving natural resources, particularly in saving a significant amount of water that is wasted when a person bathes. Conventional sprinklers consist only of a tube that carries water to an outlet, with the necessary shape to provide a certain angle of fall depending on the onion used to distribute the flow evenly, the mixture of cold water with hot water is made only with the regulation of the flows through the stopcocks that are previously installed in the bathrooms with shower. With reference to the accompanying drawings of the invention, the shower (100) with water saving system the system is characterized in that it consists of a set of elements integrated to the pipe that discharges the water in a conventional shower. The system includes a diverter device (10) of the water flow that is coupled to the connection (8) of the water pipe at a point adjacent or immediately to the wall (5), and that is designed with a distribution chamber (25 ), by means of which the water is directed in two predetermined flow paths, one at a time, for which it has a lever (15) that is inserted into a conduit of the device to move rectilinearly along it a first position in which it is blocking the passage of water towards the shower (Fig. 5), and the drift towards the tank through the angled hole (19) of the lever, to a second position in which it leaves unlocked (Fig. 6) the passage of water through the pipe (80) that goes to the shower (90), when the hole (18) of the lever is registered with the conduit of the pipe (80). The lever (15) is an elongated tubular piece in whose front section (the one that is introduced into the diverter device) are the through holes (18, 19) that serve as passage elements to direct the water flow as indicated above, according to the position in which said lever is located. The system (100) also includes a water storage tank (20) disposed below the level of the water pipe and attached to it by some suitable means, said tank is provided to contain the cold water which, when the lever (15 ) associated to the diverter device (10) is in the first position, it is referred to said tank through a duct (12) of the device (10) and a hose (17) connected to it, which is fixed to an input means (22) provided on the upper surface of the tank. The tank (20) is of any appropriate capacity and also has a water level detection system that is poured into the tank, consisting of a float (30) and an alarm switch (32) that is activated by the float when This has reached the maximum height or level of the water that is expected to be contained in the tank. As a result of the activation of the switch (32) an audible alarm (40) will be activated which, by means of intermittent sounds, will warn the user that it can already be introduced for bathing. A venturi type device (50) is placed in the water flow path, in a position between the diverter device (10) and the shower head (90) so that it influences the flow pressure and speed of the water passing through of said device. In addition, the venturi-type device (50) has a water re-entry duct (52) that is connected in water flow communication with the inside of the tank (20) by means of a hose (24) so that when the water flows through the venturi (50), when the lever is in the second position referred to above, there is a vacuum effect in the vacuum chamber (55) of said device (50) that causes the water contained in the tank is suctioned so that it re-enters (Fig. 9) to the pipe (80) that conducts the water to the shower (90), mixing with the hot water that comes from the conventional water heater (not shown)
MODO DE FUNCIONAMIENTO.OPERATING MODE.
Todo comienza por abrir el flujo de Ia regadera de manera tradicional, mediante Ia manipulación de los manerales o llaves de las válvulas de mezcla (no mostradas), cuando el fluido (que en condiciones normales está a temperatura ambiente) recorre las tuberías y llega a Ia nueva regadera ingresando primero a Ia cámara de distribución del desviador (10) que está en posición de inicio, esto es para dirigir el flujo de agua al tanque de almacenamiento (20) pasando por Ia conexión flexible (17). Cuando el agua alcanza el nivel óptimo de llenado en el tanque (20), Io cual dependerá de Ia capacidad de éste, el flotador (30) accionará de manera automática el interruptor (32) de Ia alarma (40) de llenado, el cual se alimenta por medio de una batería (35) de 9 voltios, entonces dicha alarma (40) emitirá un sonido intermitente para indicar que es tiempo de ingresar a Ia ducha y cambiar de posición Ia palanca (15) del desviador (10) de manera que el flujo de agua sea dirigido normalmente, es decir, a través del tubo (50) de efecto venturi. Al pasar el flujo de agua por este dispositivo (50), es comprimido y luego descomprimido rápidamente con Io cual se genera un vacío que succiona el agua almacenada en el tanque (20), a través de Ia manguera de reingreso (24). Mediante este proceso, se logra Ia mezcla del agua que ya viene caliente y Ia fría contenida en el tanque en Ia recámara de vacío del tubo de venturi (50); el agua ya mezclada y a una temperatura confortable pasa por el brazo (80) de Ia regadera y llega hasta Ia regadera (90) para ser descargada.Everything begins by opening the flow of the shower in a traditional way, by manipulating the ways or keys of the mixing valves (not shown), when the fluid (which is in normal conditions at room temperature) travels through the pipes and reaches The new shower by first entering the diverter distribution chamber (10) that is in the starting position, this is to direct the flow of water to the storage tank (20) through the flexible connection (17). When the water reaches the optimum level of filling in the tank (20), which will depend on its capacity, the float (30) will automatically activate the switch (32) of the filling alarm (40), which It is powered by a 9 volt battery (35), then said alarm (40) will emit an intermittent sound to indicate that it is time to enter the shower and change the position of the lever (15) of the diverter (10) so that the water flow is normally directed, that is, through the venturi tube (50). When the water flow passes through this device (50), it is compressed and then quickly decompressed with which a vacuum is generated that sucks the water stored in the tank (20), through the re-entry hose (24). Through this process, the mixture of the water that is already hot and the cold contained in the tank in the vacuum chamber of the venturi tube (50) is achieved; he Water already mixed and at a comfortable temperature passes through the arm (80) of the shower and reaches the shower (90) to be discharged.
