DESCRIPCIÓN  DESCRIPTION
MÓDULO DE PROTECCION PARA CALENTADOR DE ACS ELÉCTRICO OBJETO DE LA INVENCIÓN PROTECTION MODULE FOR ELECTRIC ACS HEATER OBJECT OF THE INVENTION
La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a un módulo de protección para calentador de ACS eléctrico, el cual aporta, a la función a que se destina, ventajas y características, que se describirán en detalle más adelante, que suponen una novedad en el estado actual de la técnica. The invention, as stated in the present specification, refers to a protection module for electric DHW heater, which contributes, to the function to which it is intended, advantages and characteristics, which will be described in detail below. , which are a novelty in the current state of the art.
Más en particular, el objeto de la invención se centra en un módulo de componentes eléctricos, destinado a su instalación en viviendas que cuentan como sistema de ACS (agua caliente sanitaria) mediante calentador o "termo" eléctrico, y cuya finalidad es proporcionar un medio de protección y de apagado automático del mismo, frente a eventuales averías o derivación eléctrica a tierra, evitando que toda la vivienda se quede sin suministro eléctrico por saltar el interruptor diferencial, comprendiendo, para ello, al menos, un interruptor diferencial y, opcionalmente, un interruptor magnetotérmico, conectados entre la toma de corriente del calentador y el resto de elementos eléctricos del mismo. More in particular, the object of the invention is focused on a module of electrical components, intended for installation in homes that have ACS (hot water) system by means of an electric heater or "thermos", and whose purpose is to provide a means protection and automatic shutdown of the same, against possible breakdowns or electrical bypass to ground, preventing the entire house from running out of power by jumping the differential switch, comprising, at least, a differential switch and, optionally, a circuit breaker, connected between the outlet of the heater and the rest of the electrical elements thereof.
CAMPO DE APLICACIÓN DE LA INVENCIÓN FIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de aparatos, dispositivos y accesorios eléctricos, centrándose particularmente en el ámbito de los calentadores de ACS eléctricos. The field of application of the present invention is part of the industry sector dedicated to the manufacture of electrical appliances, devices and accessories, particularly focusing on the field of electric DHW heaters.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Como es sabido, en las instalaciones eléctricas de las viviendas hay, normalmente, instalado un cuadro general de entrada de la acometida de suministro que comprende un interruptor diferencial. As is known, in the electrical installations of the dwellings, a general input panel of the supply connection is normally installed, comprising a differential switch.
Dicho interruptor es un dispositivo electromecánico que se coloca en las instalaciones eléctricas de corriente alterna con el fin de proteger a las personas de los contactos directos Said switch is an electromechanical device that is placed in alternating current electrical installations in order to protect people from direct contacts

HOJA DE REEMPLAZO (REGLA 26) e indirectos provocados por el contacto con partes activas de la instalación o con elementos sometidos a potencial, por ejemplo, a causa de una derivación por falta de aislamiento de partes activas de la instalación así como de protección contra eventuales incendios que pudieran provocar dichas derivaciones. REPLACEMENT SHEET (RULE 26) and indirect ones caused by contact with active parts of the installation or with elements subject to potential, for example, due to a derivation due to lack of insulation of active parts of the installation as well as protection against eventual fires that could cause said derivations.
Es un dispositivo de protección muy importante en toda instalación, tanto doméstica, como industrial, que actúa conjuntamente con la puesta a tierra de enchufes y masas metálicas de todos los aparatos eléctricos. Por ello, dicho interruptor desconecta el circuito en cuanto existe una derivación o defecto a tierra mayor que su sensibilidad. Si no existe la conexión a tierra y se produce un contacto de un cable u elemento activo a la carcasa de una máquina, el diferencial no se percatara hasta que una persona no aislada de tierra toca esta masa, entonces la corriente recorre su cuerpo hacia tierra provocando un desvío a tierra y superando ésta la sensibilidad del diferencial que en dicho momento se disparará protegiendo a la persona y evitando así su electrocución. It is a very important protection device in any installation, both domestic and industrial, that acts together with the earthing of plugs and metallic masses of all electrical appliances. Therefore, said switch disconnects the circuit as soon as there is a ground fault or fault greater than its sensitivity. If there is no ground connection and there is a contact of an active cable or element to the casing of a machine, the differential will not be noticed until a person not isolated from earth touches this mass, then the current travels its body to the ground causing a diversion to ground and overcoming this the sensitivity of the differential that at that time will be triggered protecting the person and thus avoiding their electrocution.
Por tanto, en las viviendas con calentador de ACS eléctrico, cuando se produce una avería de fuga o una derivación eléctrica a tierra por cualquier causa o mal funcionamiento, automáticamente el diferencial del cuadro general de la vivienda salta y desconecta todo el suministro de electricidad hasta que el usuario solventa el problema y vuelve a conectar el diferencial de interruptor general. Therefore, in homes with an electric DHW heater, when there is a leakage fault or an electrical grounding due to any cause or malfunction, the differential of the general panel of the house automatically jumps and disconnects all the electricity supply until that the user solves the problem and reconnects the general switch differential.
Este hecho, sin embargo, aunque previene mayores percances, provoca que otros aparatos de la vivienda también queden automáticamente desconectados y fuera de funcionamiento, lo cual puede llevar a situaciones no deseadas cuando el usuario está ausente por varios días o semanas, la más común, encontrarse los alimentos del refrigerados y/o congelador estropeados al regresar de unas vacaciones o fin de semana. This fact, however, although it prevents further mishaps, causes other appliances in the house to also be automatically disconnected and out of operation, which can lead to unwanted situations when the user is absent for several days or weeks, the most common, find spoiled food in the refrigerator and / or freezer when returning from a holiday or weekend.
Sería deseable, por tanto, poder evitar dicho inconveniente, siendo el objetivo de la presente invención el desarrollo de un módulo para incorporar en tales aparatos calentadores y solventarlo de manera práctica y segura. It would be desirable, therefore, to be able to avoid such inconvenience, the objective of the present invention being the development of a module for incorporating in such heating apparatus and solving it in a practical and safe manner.
Por otra parte, y como referencia al estado actual de la técnica, cabe señalar que, al menos por parte del solicitante, se desconoce la existencia de ningún otro módulo de protección o invención de aplicación similar que presente unas características técnicas y constitutivas On the other hand, and as a reference to the current state of the art, it should be noted that, at least by the applicant, the existence of any other protection module or invention of similar application that has technical and constitutive characteristics is unknown.

Para ello, esencialmente, dicho módulo comprende la incorporación de un interruptor diferencial, preferentemente de 16 Amperios y 10 mA de sensibilidad, incorporado en el circuito eléctrico del termo, concretamente, entre el enchufe de la toma de corriente y el resto de elementos eléctricos del mismo. Con ello, ante cualquier avería por fuga o desvío a tierra, saltará este diferencial y se desconectará solamente el aparato calentador pero no saltará el interruptor diferencial del cuadro eléctrico general de la vivienda y, por tanto, el resto de aparatos seguirán normalmente conectados. To do this, essentially, said module comprises the incorporation of a differential switch, preferably of 16 Amps and 10 mA of sensitivity, incorporated in the electrical circuit of the thermos, specifically, between the plug of the socket and the rest of the electrical elements of the same. With this, in the event of a breakdown due to leakage or diversion to the ground, this differential will jump and only the heating device will be disconnected but the differential switch of the general electrical panel of the house will not jump and, therefore, the rest of the devices will remain normally connected.
Además, preferiblemente, aunque no de manera limitativa, el módulo de la invención también contempla la inclusión de un interruptor magnetotérmico, conectado aguas abajo del diferencial descrito, siendo este, preferentemente, también de 16 Amperios, con lo cual se proporciona protección al aparato por cortocircuito y sobrecalentamiento. In addition, preferably, but not limited to, the module of the invention also contemplates the inclusion of a circuit breaker, connected downstream of the described differential, this being preferably also 16 Amps, whereby protection is provided to the apparatus by short circuit and overheating.
El descrito módulo de protección para calentador de ACS eléctrico representa, pues, una estructura innovadora de características estructurales y constitutivas desconocidas hasta ahora para el fin a que se destina, razones que unidas a su utilidad práctica, la dotan de The described protection module for electric DHW heater thus represents an innovative structure with structural and constitutive characteristics unknown until now for the purpose to which it is intended, reasons that together with its practical utility, provide it with
