Abstract

The invention relates to a system for saving drinking water. The invention comprises a hot water circuit with a recirculation system, including: a tap having a thermostatic valve calibrated to a pre-determined temperature (e.g. 36°); a first non-return valve which prevents water from entering the circuit in the opposite direction; a second non-return valve in the inlet of the boiler, preventing the entry of cold water from the external network (2); a pressure switch; and a water pump which moves the water towards the boiler when the pressure switch detects an increase in the pressure in the circuit. The system operates such that when the hot tap is opened no water can be released until the temperature pre-determined by the thermostatic valve has been reached. Once said temperature has been reached, the tap allows the release of hot and cold water so that the desired temperature can be obtained.

In this way, it is intended to avoid the waste that occurs from this good from the moment the hot water tap is opened until we obtain it, a period during which many liters are lost because it is cold. The problem that arises of not obtaining hot water until many liters of cold water have come out, is due to the distance between the boiler and the tap, which is a circumstance that would be solved with the invention presented, obtaining with it a triple benefit:
1. Ahorro de agua, ya que ésta no sale al exterior hasta que no alcanza la temperatura deseada.1. Water saving, since it does not go outside until it reaches the desired temperature.
2. Ahorro de energía; la caldera realizará un consumo menor, ya que el agua será calentada previamente.2. Energy saving; The boiler will consume less, since the water will be preheated.
3. Ahorro de tiempo en el intervalo en el que sale agua caliente; la caldera necesitará menos tiempo para calentar el agua que ha sido previamente calentada.3. Time savings in the interval in which hot water comes out; The boiler will need less time to heat water that has been previously heated.
DESCRIPCIÓNDESCRIPTION
La invención se compone de un grifo termostatico (3), que incorpora una válvula termostatica tarada (5) a una temperatura que se estima debería ser de 36°. Cuando se abre el grifo, éste abre las llaves (4) del agua fría y caliente (5). Por el propio funcionamiento de este grifo, si se ha seleccionado el agua caliente, el acceso de agua fría no se abre hasta que entra agua por el acceso de agua caliente. Inmediatamente después del acceso de agua caliente de este grifo, se coloca una válvula termostatica, que enviará hacia un circuito u otro el agua que le llegue, dependiendo de su temperatura. Si la temperatura del agua es menor de la seleccionada en la válvula termostatica tarada, la enviará otra vez a la caldera (1). En este circuito existe un presostato (7) que detecta un aumento de la presión en el mismo y acciona una pequeña bomba de agua (8) que mueve el agua hacia la caldera para continuar calentándola. El circuito cuenta con una válvula antiretorno (9), que impide que entre agua en este circuito en sentido contrario. A su vez, en el circuito existe otra válvula antiretorno (10) en la entrada de la caldera desde el agua fría de la red exterior (2). The invention is made up of a thermostatic tap (3), which incorporates a thermostatic valve tared (5) at a temperature that is estimated to be 36 °. When the tap is opened, it opens the faucets (4) of hot and cold water (5). Due to the operation of this tap, if hot water has been selected, the cold water access does not open until water enters through the hot water access. Immediately after the hot water access of this tap, a thermostatic valve is placed, which will send the water that arrives to one circuit or another, depending on its temperature. If the water temperature is lower than that selected in the thermostatic valve set, it will be sent again to the boiler (1). In this circuit there is a pressure switch (7) that detects an increase in the pressure in it and operates a small water pump (8) that moves the water towards the boiler to continue heating it. The circuit has a non-return valve (9), which prevents water from entering this circuit in the opposite direction. In turn, in the circuit there is another non-return valve (10) at the inlet of the boiler from the cold water of the external network (2).

Claims

Al entrar la bomba en funcionamiento, el agua calentada y no utilizada, retorna a la caldera, circunstancia de la que se desprende que cuando se quiera volver a utilizar agua caliente, la caldera cuente en su depósito con agua precalentada, ahorrando energía. Upon entering the pump in operation, the heated and unused water returns to the boiler, a circumstance that shows that when you want to use hot water again, the boiler has preheated water in its tank, saving energy.
Cuando el agua que se encuentre recirculando alcance la temperatura previamente seleccionada en la válvula tarada, la misma la hará llegar a la salida exterior del grifo, pudiendo éste también proporcionar agua fría si se deseara para alcanzar la temperatura finalmente deseada.When the water that is recirculating reaches the previously selected temperature in the tared valve, it will bring it to the outside outlet of the tap, which can also provide cold water if desired to reach the finally desired temperature.
Solución final: Al dejar de enviar la válvula tarada agua por el circuito de recirculación, la válvula antitetorno impide que entre agua de la red a ese circuito, produciéndose una disminución de la presión, enviando el presostato una orden a la bomba para que se pare.Final solution: By stopping sending the water rated valve through the recirculation circuit, the non-return valve prevents water from entering the circuit to that circuit, causing a decrease in pressure, sending the pressure switch an order to the pump to stop .
APLICACIÓN INDUSTRIALINDUSTRIAL APPLICATION
El ámbito de aplicación de la invención que se presenta corresponde al uso doméstico, aunque también se podrá aplicar a nivel industrial.The scope of the invention presented corresponds to domestic use, although it can also be applied at industrial level.
RE VINDICA CIONESRE VINDICA TIONS
La invención se compone de las siguientes piezas:The invention consists of the following parts:
Un grifo que incluye una válvula tarada en su interior.A tap that includes a valve tared inside.
Un presostato y una bomba, que se podrán instalar en el circuito de retorno de agua hacia la caldera (tal como aparece representado en el dibujo que se anexa), o bien^en la misma caldera, lo que se deja a decisión del fabricante.A pressure switch and a pump, which can be installed in the water return circuit to the boiler (as shown in the attached drawing), or in the same boiler, which is left to the manufacturer's decision.
Una válvula antiretorno de agua.A water return valve.
El sistema de funcionamiento de la invención es el siguiente: Se parte de un grifo termostático, en el que se incorpora una válvula termostática tarada, a una temperatura estimada de 36° Centígrados. Al abrir el grifo, éste abre las llaves de agua fría y caliente. Por el propio funcionamiento de este grifo, si se ha seleccionado agua caliente, el acceso de agua fría no se abrirá hasta que entre agua por el acceso de agua caliente. Inmediatamente después del acceso de agua de este grifo, irá colocada una válvula termostática que, dependiendo de la temperatura del agua que llegue, la enviará hacia uno u otro circuito. Si la temperatura del agua es inferior a la seleccionada en la válvula termostática tarada, la devolverá hacia la caldera. En este circuito existe un presostato, que detecta uri aumento de la presión en el mismo y acciona una pequeña bomba de agua, que la lleva a la caldera para seguir calentándola. El circuito dispone de una válvula antiretorno, que impide que entre agua en sentido contrario en este circuito. A su vez, existe otra válvula antiretorno en la entrada de la caldera desde el agua fría de la red exterior. Al entrar la bomba en funcionamiento, la caldera recibirá de nuevo agua que ya ha sido calentada previamente por la misma.The operating system of the invention is as follows: It is based on a thermostatic tap, in which a thermostatic valve is incorporated, at an estimated temperature of 36 ° Celsius. When you open the tap, it opens the hot and cold water faucets. Due to the operation of this tap, if hot water has been selected, the cold water access will not open until water enters through the hot water access. Immediately after the access of water from this tap, a thermostatic valve will be placed which, depending on the temperature of the water that arrives, will send it to one or the other circuit. If the water temperature is lower than that selected in the thermostatic valve set, it will return it to the boiler. In this circuit there is a pressure switch, which detects an increase in the pressure in it and drives a small water pump, which takes it to the boiler to continue heating it. The circuit has a non-return valve, which prevents water from entering the opposite direction in this circuit. In turn, there is another non-return valve at the inlet of the boiler from the cold water of the external network. Upon entering the pump in operation, the boiler will again receive water that has been previously heated by it.
Mientras el agua está recirculando, alcanza la temperatura que se ha fijado previamente en la válvula tarada, la cual la reenviará a la salida exterior del grifo, haciendo éste que entre agua fría de la red si fuese necesario para regular la temperatura. De esta forma, se obtiene agua caliente de manera instantánea. While the water is recirculating, it reaches the temperature that has been previously set in the tared valve, which will be forwarded to the outside tap outlet, causing it to enter cold water from the network if necessary to regulate the temperature. In this way, hot water is obtained instantly.
