Description

SISTEMA DE ACCIONAMIENTO DE GRIFOS O MONOMANDOS DE AGUA SANITARIA POR SENSOR DE TACTO Y PULSADOR ELECTRÓNICO SYSTEM OF OPERATION OF TAPES OR MONOMANDOS OF SANITARY WATER BY SENSOR OF TOUCH AND ELECTRONIC PUSH BUTTON
La presente memoria descriptiva se refiere, como su titulo indica, a un sistema de accionamiento de grifos o monomandos de agua sanitaria por sensor de tacto y pulsador electrónico, ideado para propiciar la apertura del agua tanto fria como caliente, o bien la mezcla de ambas preestablecida en el grifo o monomando.The present specification refers, as its title indicates, to a system for the operation of taps or sanitary water controls by touch sensor and electronic push button, designed to promote the opening of both cold and hot water, or the mixture of both preset on the tap or mixer.
En la actualidad, la mayoría de grifos y monomandos son accionados manualmente tanto para abrir como para cerrar el flujo del agua sanitaria, siendo también conocidos los pulsadores que mediante la presión ejercida sobre ellos facilitan la salida del agua, y que en algunos modelos tienen un tiempo preestablecido para cerrar la salida una vez que se ha dejado de presionar.At present, the majority of taps and single-lever controls are manually operated both to open and to close the flow of sanitary water, the pushbuttons that, by means of the pressure exerted on them, facilitate the exit of water, and which in some models have a preset time to close the exit once it has stopped pressing.
También son conocidos algunos sistema de aperturas de grifos y monomandos, los cuales integran ciertos sensores que detectan la presencia humana y propician la apertura del agua automáticamente.Also known are some faucet and single lever opening systems, which integrate certain sensors that detect human presence and automatically promote water opening.
Los grifos y monomandos manuales conocidos en la actualidad conllevan el inconveniente de producir ciertos tiempos muertos en su manipulación, pues cada vez que son accionados hay que prestar atención si deseamos agua fria o caliente, o bien qué tipo de mezcla de ambas, lo cual evidentemente precisa de una atención aunque sea momentáneamente, suponiendo también un problema el agua que se desperdicia, asi como el deterioro prematuro de los mecanismos de estos grifos o monomandos ante sus continuos accionamientos .The manual faucets and manual controls known today have the disadvantage of producing certain dead times in their handling, because every time they are operated, attention must be paid if we want cold or hot water, or what kind of mixture of both, which obviously it requires attention, even if it is momentarily, also the problem of wasted water, as well as the premature deterioration of the mechanisms of these faucets or monomandos before their continuous drives.
En cuanto a los grifos y monomandos cuya apertura se realiza por medio de detectores de presencia, hay que mencionar como inconveniente principal, la importante cantidad de agua que se desperdicia, pues este tipo de aperturas proporciona una dosis de agua, cuya cantidad depende del reglaje del temporizador que conlleva el mecanismo, suponiendo también otro inconveniente en este tipo de aperturas por detectores de presencia tener que estar actuando repetidas veces sobre el detector, cuando se precisan cantidades de agua importantes como en el caso de las cocinas, tanto familiares como industriales.As for the faucets and controls whose opening is carried out by means of presence detectors, it is necessary to mention as a main drawback, the significant amount of water that is wasted, since this type of openings provides a dose of water, the amount of which depends on the setting of the timer that the mechanism entails, also supposing another inconvenience in this type of openings by presence detectors having to be acting repeatedly on the detector, when significant amounts of water are required as in the case of kitchens, both familiar and industrial.
Otro inconveniente que comportan los sistemas actuales de apertura de grifos y monomandos por detectores de presencia consiste en que estos no funcionan si no están correctamente limpios, o bien se ensucian accidentalmente, suponiendo también un problema la fragilidad y complejidad del mantenimiento de estos dispositivos, lo cual conlleva un mdeseado deterioro que inhabilita su funcionamiento, en cuyo momento generalmente hay que sustituir el grifo monomando completo .Another disadvantage of the current systems for opening taps and controls by presence detectors is that they do not work if they are not properly cleaned, or they get dirty accidentally, also assuming the fragility and complexity of maintaining these devices is a problem, which entails a moderate deterioration that disables its operation, at which time it is generally necessary to replace the complete mixer tap.
Para solventar la problemática anteriormente citada en cuanto a la apertura y cierre de grifos y monomandos, se ha ideado el sistema de accionamiento de grifos y monomandos de agua sanitaria por sensor de tacto y pulsador electrónico objeto de la presente invención, el cuan consta de un sensor de tacto que puede quedar inserto en cualquier parte del grifo o monomando, asi como situado independientemente de éstos. El antedicho sensor de tacto está capacitado para mandar la señal tanto por cable directo como de forma inalámbrica, la cual es captada por una base que a su vez la transmite a los oportunos mecanismo, como por ejemplo y entre otros, relés de mando, cuya misión consiste en abrir o cerrar las válvulas de paso del agua, tanto fria como caliente a la vez. Lógicamente, el grifo o monomando proporciona el agua según el posicionamiento de su mando, de tal manera, que una vez posicionado el antedicho mando en agua fria o caliente, o bien una mezcla de ambas, siempre que se accione el sensor de tacto, tendremos salida del agua deseada.In order to solve the aforementioned problem regarding the opening and closing of taps and mixer taps, the sanitary water faucets and single lever actuation system has been devised by a touch sensor and electronic push button object of the present invention, when it comprises touch sensor that can remain insert anywhere in the tap or mixer, as well as located independently of them. The aforementioned touch sensor is capable of sending the signal both by direct cable and wirelessly, which is picked up by a base that in turn transmits it to the appropriate mechanism, such as and among others, control relays, whose mission is to open or close the water passage valves, both cold and hot at the same time. Logically, the tap or mixer provides the water according to the positioning of your control, in such a way that once the above control is positioned in cold or hot water, or a mixture of both, whenever the touch sensor is activated, we will have Desired water outlet.
Otra particularidad esencial de la presente invención consiste en que opcionalmente la base de mando puede incorporar un temporizador para mandar dosis de agua de cantidad preestablecida, o bien dicha base no efectuar el corte de agua hasta que el usuario no envié la señal de corte a través del sensor de tacto. En caso de averiarse algún elemento del sistema, el grifo o monomando queda operativo con la simple operación de posicionar manualmente en abierto las válvulas de paso mediante su mando exterior.Another essential feature of the present invention is that the command base may optionally incorporate a timer to send doses of water of a predetermined amount, or said base not to perform the water cut until the user does not send the cut signal through of the touch sensor. In case of failure of any element of the system, the faucet or mixer is operative with the simple operation of manually positioning the open valves by means of its external control.
Una solución optativa de la presente invención consiste en incorporar un pulsador electrónico en el grifo o monomando, el cual, según el número de actuaciones que recibe, proporciona el agua fria, mezclada o caliente. La presente invención aporta sobre los medios conocidos en la actualidad la esencial ventaja de ahorrar estimables cantidades de agua, pues es de tener en cuenta que puede abrirse y cerrarse el flujo a voluntad, u opcionalmente temporizarse las dosis de salida según necesidad, suponiendo también una ventaja el que las válvulas de paso contienen el oportuno mando manual, el cual garantiza que el grifo o monomando este habilitado en todo momento .An optional solution of the present invention is to incorporate an electronic push-button in the tap or mixer, which, depending on the number of actions it receives, provides cold, mixed or hot water. The present invention provides over the known means at present the essential advantage of saving considerable amounts of water, since it is to be taken into account that the flow can be opened and closed at will, or optionally timed out the output doses as needed, also assuming a advantage that the pass valves contain the appropriate manual control, which guarantees that the tap or mixer is enabled at all times.
Otra ventaja que se aporta consiste en el ahorro de agua caliente, lo cual y consecuentemente, supone un estimable ahorro energético.Another advantage that is provided is the saving of hot water, which and consequently, represents an estimated energy saving.
