La presente invención, tal y como se expresa en el enunciado de esta memoria descriptiva, se refiere a un economizador de agua y energía cuya finalidad consiste en proporcionar un dispositivo que instalado en la red de agua justo antes de cualquier tipo de grifo y conectándolo a las tomas de agua del mismo, permita ahorrar la cantidad de agua que se desperdicia habitualmente desde que se solicita agua caliente desde un grifo hasta que ésta llega a la temperatura deseada, evitando además que la energía utilizada en calentar el agua hasta que se llega a la temperatura programada se desperdicie . ANTECEDENTES DE LA INVENCIÓNThe present invention, as expressed in the statement of this specification, refers to a water and energy economizer whose purpose is to provide a device that installed in the water network just before any type of tap and connecting it to the water inlets of the same, allow to save the amount of water that is usually wasted from when hot water is requested from a tap until it reaches the desired temperature, also preventing the energy used to heat the water until it reaches the programmed temperature is wasted. BACKGROUND OF THE INVENTION
Actualmente, se puede observar en nuestros hogares, hoteles, instalaciones deportivas, etc., que cada vez que se solicita agua caliente, bien sea en el baño, en la cocina o donde se encuentre la correspondiente instalación, transcurre un tiempo desde que se abre el correspondiente grifo hasta que el agua llega a la temperatura deseada. Todo el agua aún no suficientemente caliente que sale desde que se abre el grifo hasta que se obtiene el agua con la temperatura deseada se pierde por el correspondiente desagüe, con lo que se dan inconvenientes a un desaprovechamiento del agua y de la energía empleada en calentarla. La cantidad de agua que se desperdicia en cada apertura, está en función de la distancia desde el elemento calefactor, bien sea caldera, calentador u otro hasta el grifo desde donde se solicita el agua, además de en función del tiempo que tarde en calentar el agua la correspondiente caldera o similar.Currently, it can be observed in our homes, hotels, sports facilities, etc., that every time hot water is requested, either in the bathroom, in the kitchen or where the corresponding installation is located, a time elapses since it opens the corresponding tap until the water reaches the desired temperature. All the water not yet hot enough that comes out from the moment the tap is opened until the water with the desired temperature is obtained is lost through the corresponding drain, which causes inconvenience to the wasted water and energy used to heat it. . The amount of water that is wasted at each opening, is a function of the distance from the heating element, either boiler, heater or other to the tap from where the water is requested, in addition to depending on the time it takes to heat the water the corresponding boiler or similar.
La patente ES 2299337 aborda la referida problemática, detallando un sistema de gestión inteligente de ahorro de agua que se caracteriza porque al detectarse la apertura del correspondiente grifo, un sensor controla la temperatura del agua que llega al mismo, de tal modo que si dicha temperatura se encuentra por debajo de una temperatura determinada, el agua se hace recircular hacia un calderin donde se va almacenando hasta que el sensor detecta una temperatura óptima. Dicha patente presenta inconvenientes relativos a que requiere un depósito auxiliar o calderin donde se vaya almacenando el agua hasta que se alcance la temperatura óptima, determinando una mayor complejidad en la instalación y un aumento de su coste.Patent ES 2299337 addresses the aforementioned problem, detailing an intelligent water saving management system characterized in that when the opening of the corresponding tap is detected, a sensor controls the temperature of the water that reaches it, so that if said temperature is below a certain temperature, the water is recirculated to a boiler where it is stored until The sensor detects an optimum temperature. This patent has drawbacks related to the fact that it requires an auxiliary tank or boiler where the water is stored until the optimum temperature is reached, determining greater complexity in the installation and an increase in its cost.
Por otra parte, en el modelo de utilidad ES 1065941 se detalla una instalación sanitaria para el ahorro de agua que se caracteriza porque los grifos presentan tres conductos, uno de agua fría, otro de agua caliente y otro de retorno, de manera que dentro de él existe una cámara con una válvula termostática, la cual si no recibe la temperatura determinada no se abre, haciendo que el agua caliente pero que todavía no tiene la temperatura deseada se reenvíe de nuevo a la caldera a través del conducto de retorno. Una vez que el agua alcanza la correspondiente temperatura, la válvula se abre permitiendo el paso del agua caliente a otra cámara donde se puede mezclar con el agua fría y salir a través del grifo. Este modelo de utilidad del estado de la técnica presenta inconvenientes relativos a que se condiciona el ahorro de agua al empleo de un grifo específico, por lo que el sistema requiere de una grifería especial, no permitiendo el uso de otro tipo de grifos para lograr el correspondiente ahorro de agua y energía, de manera que el sistema correspondiente presenta poca adaptabilidad a instalaciones convencionales y un alto coste.On the other hand, in the utility model ES 1065941 a sanitary installation for water saving is detailed that is characterized in that the taps have three ducts, one of cold water, another of hot water and another of return, so that within there is a chamber with a thermostatic valve, which if it does not receive the determined temperature does not open, causing the hot water but which does not yet have the desired temperature to be sent back to the boiler through the return duct. Once the water reaches the corresponding temperature, the valve opens allowing the passage of hot water to another chamber where it can be mixed with cold water and out through the tap. This utility model of the state of the art has drawbacks related to the fact that water saving is conditioned to the use of a specific tap, so the system requires a special tap, not allowing the use of other types of taps to achieve corresponding saving of water and energy, so that the corresponding system presents little adaptability to conventional installations and a high cost.

En proximidad de cada grifo 11, ducha 12 o elemento similar al que se quiera aplicar el economizador se intercala en sus tomas de agua el circuito economizadorIn the vicinity of each tap 11, shower 12 or similar element to which the economizer is to be applied, the economizer circuit is inserted in its water connections
10, el cual incluye, según puede apreciarse en la figura10, which includes, as can be seen in the figure
1, los siguientes elementos:1, the following elements:
Una entrada de agua fría de red 2 conectada con una salida de agua fría 4 hacia el grifo o similar 11, 12 a través de una electroválvula de agua fría 9.A cold water inlet of network 2 connected with a cold water outlet 4 towards the tap or the like 11, 12 through a cold water solenoid valve 9.
Una entrada de agua caliente 1 proviniente de la caldera o análogo 15 conectada con una salida de agua caliente 3 hacia el grifo o similar 11, 12, a través de un detector de caudal 6, un detector de temperatura 7 y una electroválvula de agua caliente 8 conectados en serie .A hot water inlet 1 from the boiler or the like 15 connected with a hot water outlet 3 to the tap or the like 11, 12, through a flow detector 6, a temperature detector 7 and a hot water solenoid valve 8 connected in series.
Además, la referida electroválvula de agua caliente 8 presenta una salida a circuito de retorno 5 que conecta con una conducción de agua de retorno unida en proximidad de la caldera o análogo 15 a su toma de agua fría.In addition, said hot water solenoid valve 8 has a return circuit outlet 5 that connects with a return water line connected in proximity to the boiler or the like 15 to its cold water outlet.
En proximidad de la conexión de la conducción de agua de retorno con la toma de agua fría de la caldera o análogo 15, y tal como se aprecia en la figura 2, hay respectivas válvulas anti-retorno 14; mientras que en la referida conducción de agua de retorno se dispone una bomba de impulsión 13, según puede verse también en la figura 2.In the vicinity of the connection of the return water line with the cold water outlet of the boiler or the like 15, and as seen in Figure 2, there are respective non-return valves 14; while in the aforementioned return water line a discharge pump 13 is arranged, as can also be seen in Figure 2.
Con la estructura que se ha descrito, el circuito 10 del presente ejemplo presenta el siguiente funcionamiento :With the structure described, circuit 10 of the present example has the following operation:
Cuando desde cualquier punto de consumo de agua dotado del dispositivo, tales como el grifo 11 o la ducha 12, se solicita agua caliente, el correspondiente detector de caudal 6 detecta el paso de agua y activa al detector de temperatura 7. Inmediatamente, el detector de temperatura 7 hace una lectura de la temperatura del agua y si ésta no alcanza la temperatura deseada envía una señal a las electroválvulas 8 y 9, las cuales cierran el paso de agua a las salidas 3 y 4, correspondientes a las tomas de agua caliente y fría respectivamente del grifo 11 o similar; accionando simultáneamente la bomba de impulsión 13. Dicha bomba de impulsión 13 hace que el agua aún no suficientemente caliente salga por la salida 5 correspondiente a la salida circuito de retorno y llegue a la red justo antes de la entrada de agua fría de la caldera 15 para ser reutilizada por ésta, tal y como puede verse en la figura 2.When hot water is requested from any point of water consumption provided with the device, such as the tap 11 or shower 12, the corresponding flow detector 6 detects the passage of water and activates the temperature detector 7. Immediately, the detector of temperature 7 makes a reading of the water temperature and if it does not reach the desired temperature it sends a signal to the solenoid valves 8 and 9, which close the water passage to the exits 3 and 4, corresponding to the hot water outlets and cold respectively of tap 11 or the like; by simultaneously driving the discharge pump 13. Said discharge pump 13 causes the water not yet hot enough to exit the outlet 5 corresponding to the return circuit output and reach the network just before the cold water enters the boiler 15 to be reused by it, as can be seen in figure 2.
En el momento en que el detector de temperatura 7 detecta que la temperatura del agua caliente es la deseada acciona la electroválvula 8 para permitir el paso de agua caliente por la salida 3 y la electroválvula 9 para posibilitar el paso de agua fría por la salida 4, al tiempo que efectúa la desconexión de la bomba de impulsión 13.At the moment when the temperature detector 7 detects that the temperature of the hot water is the desired, actuates the solenoid valve 8 to allow the passage of hot water through the outlet 3 and the solenoid valve 9 to enable the passage of cold water through the outlet 4, while disconnecting the drive pump 13.
En el caso de que se solicite solo agua fría, por el detector de caudal 6 no circula agua y por lo tanto no se activa el detector de temperatura 7, con lo que las electroválvulas 8 y 9 no se cierran, permitiendo asi la salida de agua a través de la salida a la toma de agua fría 4.In the case that only cold water is requested, the flow detector 6 does not circulate water and therefore the temperature detector 7 is not activated, so that the solenoid valves 8 and 9 do not close, thus allowing the output of water through the outlet to the cold water outlet 4.
En el supuesto caso de que el detector de caudal 6 se dañara, el detector de temperatura 7 no se activaría y por lo tanto las electroválvulas 8 y 9 permanecerían abiertas permitiendo paso de agua a través de ellas y evitando así quedarse sin suministro de agua. In the event that the flow detector 6 is damaged, the temperature detector 7 would not be activated and therefore the solenoid valves 8 and 9 would remain open allowing water to pass through them and thus avoiding running out of water supply.
