La aplicación industrial de esta invención se halla en el sector de los sistemas y aplicaciones de electroválvulas, y mas concretamente dispositivos y electroválvulas para ahorro de agua. The industrial application of this invention is in the field of solenoid valve systems and applications, and more specifically devices and solenoid valves for saving water.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Aunque no se ha encontrado ninguna invención idéntica a la descrita, exponemos a continuación los documentos encontrados que reflejan el estado de la técnica relacionado con la misma.
Así el documento ES0437467A1 hace referencia a un dispositivo de irrigación por goteo, para la dosificación de un fluido procedente de un sistema de irrigación, a una velocidad determinada, caracterizado por comprender un cuerpo emisor tubular cónico que tiene, un orificio en su pared para permitir que pase líquido hacia afuera a través del mismo, desde la parte interna de icho cuerpo emisor cónico y, como mínimo, una ranura longitudinal en su pared externa que se extiende sustancialmente en la longitud del cuerpo del emisor y al extremo cerrado del mismo, existiendo además una caperuza tubular del emisor fijada con capacidad de desmontaje al cuerpo emisor cónico para recibir el líquido procedente de dicho cueipo emisor y conjuntamente con la ranura del mismo, proporciona un paso de restricción de volumen. El documento citado, pese a describir un dispositivo de irrigación por goteo, que permite el ahorro de agua, no guarda relación alguna con la forma en que el dispositivo objeto de la presente invención realiza su función. Although no invention identical to that described has been found, we present below the documents found that reflect the state of the art related thereto. Thus, document ES0437467A1 refers to a drip irrigation device, for the dosage of a fluid from an irrigation system, at a certain speed, characterized by comprising a conical tubular emitting body that has a hole in its wall to allow that liquid passes out through it, from the internal part of the conical emitter body and, at least, a longitudinal groove in its outer wall that extends substantially the length of the emitter body and to the closed end thereof, existing furthermore, a tubular cap of the emitter fixed removably to the conical emitter body to receive the liquid coming from said emitter body and together with the groove of the same, provides a volume restriction passage. The cited document, despite describing a drip irrigation device, which allows saving water, does not bear any relation to the way in which the device object of the present invention performs its function.
ES1068770U describe un economizador de agua y energía, aplicable a grifos, duchas y en general elementos con salida de agua caliente y salida de agua fría; proviniendo el agua caliente de una salida de agua caliente de una caldera, calentador o análogo y el agua fría de una conducción de red de que también alimenta a la caldera o análogo; que en proximidad de cada grifo, ducha o elemento similar al que se quiera aplicar el economizador se intercala en sus tomas de agua un circuito economizador que presenta: - Una entrada de agua fría de red conectada con una salida de agua fría hacia el grifo o similar a través de una electroválvula de agua fría; - una entrada de agua caliente proveniente de la caldera o análogo conectada con una salida de agua caliente hacia el grifo o similar a través de un detector de caudal, un detector de temperatura y una electroválvula de agua caliente conectados en serie; -presentando además la referida electroválvula de agua caliente una salida a circuito de retomo que conecta con una conducción de agua de retomo unida en proximidad de la caldera o análogo a su toma de agua fría; - existiendo en proximidad de la conexión de la conducción de agua de retomo con la toma de agua fría de la caldera o análogo respectivas válvulas anti-retomo, y disponiendo dicha conducción de agua de
retomo de una bomba de impulsión; de manera que cuando se solicita agua caliente del grifo o similar el detector de caudal detecta paso de agua activando al detector de temperatura para que haga lectura de la temperatura del agua y si esta no es suficientemente caliente cierra las electroválvulas enviando el agua por la salida de retomo hacia la caldera o análogo; y de manera que en el momento en que el detector de temperatura detecta que la temperatura de agua caliente es la deseada acciona la electroválvula de agua caliente para permitir el paso de agua caliente por la salida de agua caliente, y la electroválvula de agua fría para posibilitar el paso de agua fría por la salida de agua fría, al tiempo que se desconecta la bomba de impulsión. El economizador descrito en el citado documento recoge un sistema de electroválvulas con sistema de retomo de agua hacia la caldera, convirtiéndolo en un sistema mucho mas complejo que el que propone la invención principal. ES1068770U describes a water and energy economizer, applicable to taps, showers and in general items with hot water outlet and cold water outlet; the hot water coming from a hot water outlet of a boiler, heater or similar, and the cold water from a network conduit that also feeds the boiler or similar; that near each tap, shower or similar element to which the economizer is to be applied, an economizer circuit is inserted in its water intakes that has: - A cold water inlet from the mains connected to a cold water outlet to the tap or similar through a cold water solenoid valve; - a hot water inlet from the boiler or similar connected with a hot water outlet to the tap or similar through a flow sensor, a temperature sensor and a hot water solenoid valve connected in series; - the aforementioned hot water solenoid valve also having an outlet to the return circuit that connects with a return water line connected to the proximity of the boiler or similar to its cold water intake; - existing in proximity of the connection of the return water conduction with the cold water intake of the boiler or similar respective non-return valves, and having said water conduction of return of an impulsion pump; so that when hot water is requested from the tap or similar, the flow detector detects the passage of water, activating the temperature detector to read the water temperature and if it is not hot enough, it closes the solenoid valves sending the water through the outlet return to the boiler or similar; and so that when the temperature detector detects that the hot water temperature is the desired one, it activates the hot water solenoid valve to allow the passage of hot water through the hot water outlet, and the cold water solenoid valve to allow the passage of cold water through the cold water outlet, while disconnecting the impulsion pump. The economizer described in the aforementioned document includes a system of solenoid valves with a system for returning the water to the boiler, making it a much more complex system than that proposed by the main invention.
ES0045639U propone un difusor para grifos perfeccionado, constituido por un cuerpo sensiblemente tronco-cónico, -de material impermeable, elástico y flexible-, en el que se distinguen intema y externamente tres zonas bien diferenciadas, estando constituida la central por unas depresiones y resaltes anulares que se corresponden extema e internamente, formando una sección sinuosa que proporciona un gran aumento de la flexibilidad natural; la mas próxima a la base menor lisa, con un cajeado interior en el que se aloja una pieza ungida con perforaciones paralelas al eje, destinada a dividir la vena líquida; y presentando la zona mas próxima a la base mayor una parte lisa comprendida entre dos resalles anulares y que internamente lleva unos tabiquillos discoidales perforados en su centro, destinados a fijar al grifo el dispositivo por la simple y firme presión que proporciona la elasticidad del material haciendo que los citados tabiquillos discoidales adopten una posición oblicua al eje. El difusor descrito no incorpora ninguna característica con la que se pueda comparar el dispositivo de ahorro de agua objeto de la invención principal. ES0045639U proposes an improved diffuser for taps, made up of a substantially truncated-conical body, -made of waterproof, elastic and flexible material-, in which three well-differentiated areas are internally and externally distinguished, the central one being made up of annular depressions and projections that correspond externally and internally, forming a sinuous section that provides a great increase in natural flexibility; the one closest to the smaller smooth base, with an internal cavity in which an anointed piece with perforations parallel to the axis is housed, intended to divide the liquid vein; and the area closest to the larger base having a smooth part comprised between two annular projections and internally carrying perforated discoidal partitions in its center, intended to fix the device to the tap by the simple and firm pressure provided by the elasticity of the material making that said discoidal partitions adopt a position oblique to the axis. The diffuser described does not incorporate any characteristic with which the water saving device object of the main invention can be compared.
ES1076340U se refiere a un grifo mono mando que ahorra agua y energía, en el que el giro del encaje de la maneta de un grifo mono mando en el sentido
correcto, de tal manera que la maneta del grifo mono mando quede centrada con el cano del grifo, o el eje longitudinal de la maneta quede perpendicular al usuario de tal manera que en esa posición se produzca la vía de agua fría, que un giro hacia la izquierda, desde la posición anterior sea el estado susceptible de agua mezcla o templada, y que el giro total hacia la izquierda sea la posición susceptible de caliente. En este caso, aunque sí se hace alusión al ahorro de agua, no comprende ninguno de los elementos no configuración que se describe en la invención principal. ES1076340U refers to a single control tap that saves water and energy, in which turning the socket of the handle of a single control tap in the direction correct, in such a way that the handle of the single-control tap is centered with the tap shaft, or the longitudinal axis of the handle is perpendicular to the user in such a way that in that position the cold water path is produced, that a turn towards the left, from the previous position, is the state susceptible to mixed or warm water, and the total turn to the left is the position susceptible to hot. In this case, although it does refer to saving water, it does not include any of the non-configuration elements described in the main invention.
Conclusiones: Como se desprende de la investigación realizada, ninguno de los documentos encontrados soluciona los problemas planteados como lo hace la invención propuesta. Conclusions: As can be seen from the research carried out, none of the documents found solves the problems raised as the proposed invention does.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
El dispositivo de ahorro de agua en grifos objeto de la presente invención se constituye a partir de un circuito formado por dos electroválvulas y un micro interruptor que las acciona, y una pequeña fuente de alimentación o un adaptador de corriente de red domestica The water saving device in taps object of the present invention is constituted from a circuit formed by two electrovalves and a microswitch that actuates them, and a small power supply or a domestic mains power adapter.
Cada electroválvula se coloca en la toma de la pared del agua caliente y fita respectivamente, y el micro interruptor que las activa queda instalado en el marco de la puerta de debajo del fregadero, de forma que al estar cerrada dicha puerta no sea actuado, pero cuando se realiza una ligera presión con la rodilla sí sea actuado y da paso de corriente a las dos electroválvulas. Each solenoid valve is placed on the wall outlet for hot water and fita respectively, and the microswitch that activates them is installed in the frame of the door under the sink, so that when the door is closed, it is not actuated, but When light pressure is applied with the knee, it is actuated and it gives current to the two solenoid valves.
El grifo, por tanto, queda siempre abierto y en la posición que mas convenga al usuario, ya sea agua totalmente fría, intermedias o totalmente caliente, pues solo sale agua cuando se acciona el dispositivo con la rodilla, teniendo las manos libres y pudiendo accionar o parar el chorro a voluntad.
El accionamiento, en los casos en que el fregadero no disponga de una puerta sino de un cajón, podrá adaptarse para el mismo, incluso instalar el micro interruptor tras el zócalo o rodapié de la cocina. The tap, therefore, is always open and in the position that best suits the user, whether it is totally cold, intermediate or totally hot water, since only water comes out when the device is activated with the knee, having the hands free and being able to operate or stop the jet at will. The drive, in cases where the sink does not have a door but a drawer, can be adapted for it, even installing the micro switch behind the kitchen plinth or skirting board.
