D E S C R I P C I Ó ND E S C R I P C I Ó N
La presente invención tiene por objeto un extractor de aire encastrable, del tipo de los que comprenden: una carcasa-soporte de material aislante; un rodete dotado de paletas actuando como ventilador axial; un electromotor; y un circuito electrónico.The object of the present invention is a recessed air extractor, of the type comprising: a support housing of insulating material; an impeller equipped with vanes acting as axial fan; an electric motor; and an electronic circuit.
Es frecuente a conveniencia de instalar extractores en pequeños recintos o aposentos, como salas de baño, lavabos, despensas, bodegas o cuartos fregaderos, etc, que carezcan de ventilación directa al exterior.It is common for the convenience of installing extractors in small enclosures or rooms, such as bathrooms, toilets, pantries, cellars or sink rooms, etc., that lack direct outside ventilation.
Los extractores habitualmente conocidos, frecuentemente son de difícil montaje para ser encastrados a los conductos individuales de aireación o de extracción estática normalizados que se instalan en casi todos los edificios. Además, con estos extractores habitualmente conocidos no es fácil realizar su montaje en una pared, techo o ventana y además este montaje requiere un volumen del que con frecuencia no se dispone.The commonly known extractors are often difficult to assemble to the individual standardized aeration or static extraction ducts that are installed in almost all buildings. In addition, with these commonly known extractors it is not easy to mount them on a wall, ceiling or window and this assembly also requires a volume that is often not available.
La invención se propone superar estos inconvenientes. Esta finalidad se consigue por medio de un extractor del tipo referida al principio, que está caracterizado porque dicha carcasa-soporte comprende: una zona cilindrica; y una zona laminar dispuesta solidariamente en substancial ortogonalidad al eje de dicha zona cilindrica; dicha zona cilindrica presentando una oquedad parcialmente ocupada por un cuerpo cilindrico coaxial en el que se alojan dicho rodete, dicho electromotor y dicho circuito electrónico; dicha zona cilindrica y dicho cuerpo cilindrico estando unidos mediante unos brazos radiales; y, entre dicha zona cilindrica y dicho cuerpo cilindrico, existiendo un paso que rodea dicho cuerpo cilindrico; y dicha zona laminar presentando en su periferia, un tramo elástico que tiende a rebasar dicha periferia y que es apto para anclarse amoviblemente en una muesca de un borde lateral de una tapa frontal, la cual es en forma de cazoleta de reducido espesor y que está dotada de una ventana.The invention aims to overcome these drawbacks. This purpose is achieved by means of an extractor of the type referred to at the beginning, which is characterized in that said support-housing comprises: a cylindrical zone; and a laminar zone arranged jointly in substantial orthogonality to the axis of said cylindrical zone; said cylindrical zone having a cavity partially occupied by a coaxial cylindrical body in which said impeller, said electromotor and said electronic circuit are housed; said cylindrical zone and said cylindrical body being joined by radial arms; and, between said cylindrical zone and said cylindrical body, there is a passage surrounding said cylindrical body; and said laminar zone presenting at its periphery, an elastic section that tends to exceed said periphery and which is apt to be removably anchored in a notch of a lateral edge of a front cover, which is in the form of a small bowl and is provided with a window.
El extractor objeto de la invención presenta varias ventajas con respecto a los modelos que actualmente están comercializados en el mercado, y estas ventajas se basan en su bajo perfil, este pequeño espesor de la tapa permite ser instalado en una pared techo o ventana según la necesidad.The extractor object of the invention has several advantages with respect to the models that are currently marketed in the market, and these advantages are based on its low profile, this small thickness of the lid allows it to be installed on a ceiling or window wall as needed .
Otras ventajas y características de la invención se aprecian a partir de la siguiente descripción, en la qué, sin ningún carácter limitativo, se relata un modo preferente de realización de la invención, haciendo mención de los dibujos que se acompañan. Las figuras muestran:Other advantages and features of the invention can be seen from the following description, in which, without any limitation, a preferred embodiment of the invention is mentioned, mentioning the accompanying drawings. The figures show:

Fig. 4 es una vista frontal explosionada en perspectiva de la carcasa-soporte del extractor y la tapa, mostrándose esquemáticamente el sistema de montaje.Fig. 4 is an exploded front perspective view of the housing-support of the extractor and the cover, showing the assembly system schematically.
El aparato extractor objeto de la invención comprende, en primer lugar, una carcasa-soporte que preferentemente, se moldea de una sola pieza a partir de una materia plástica apropiada. Esta carcasa-soporte está formada por una zona cilindrica 1 , y una zona laminar 2, cuya orientación es perpendicular al eje ideal de la zona cilindrica; preferentemente es de forma cuadrada si bien sus lados son ligeramente cóncavos..The extractor apparatus object of the invention comprises, first of all, a housing-support which is preferably molded in one piece from an appropriate plastic material. This support housing is formed by a cylindrical zone 1, and a laminar zone 2, whose orientation is perpendicular to the ideal axis of the cylindrical zone; preferably it is square in shape although its sides are slightly concave ..
La zona cilindrica 1 se destina al alojamiento del conjunto formado por el rodete 6 dotado de paletas, que actúa como ventilador axial, el electromotor 5 y el circuito electrónico 7, útil para diferentes aplicaciones. En el interior de dicha zona cilindrica 1 también se halla una oquedad que está ocupada parcialmente por un cuerpo cilindrico 3, preferentemente moldeado de una sola pieza con el conjunto, situado en posición coaxial con respecto al la zona cilindrica 1 ; por lo expuesto, se aprecia que entre la zona cilindrica 1 y el cuerpo cilindrico 3, queda un paso. Este cuerpo cilindrico 3 está relacionado per medio de unos brazos radiales 4 con la zona cilindrica 1. El electromotor 5 se aloja, prácticamente en su totalidad, en el interior del cuerpo cilindrico 3 y el rodete 6 se enclava directamente sobre el eje del electromotor 5. Es preferente que el rodete 6 se moldee de una sola pieza de un material plástico apropiado para cubrir parcialmente el electromotor; con ello se elimina toda posibilidad de establecer contacto con zonas del extractor que puedan estar bajo tensión eléctrica, ni tan siquiera utilizando el calibre de prueba requerido en los ensayos que dicta la norma de seguridad eléctrica.The cylindrical zone 1 is intended for housing the assembly formed by the impeller 6 provided with vanes, which acts as an axial fan, the electric motor 5 and the electronic circuit 7, useful for different applications. Inside said cylindrical zone 1 there is also a recess that is partially occupied by a cylindrical body 3, preferably molded in one piece with the assembly, located in coaxial position with respect to the cylindrical zone 1; Therefore, it can be seen that between the cylindrical zone 1 and the cylindrical body 3, a step remains. This cylindrical body 3 is connected by means of radial arms 4 with the cylindrical zone 1. The electric motor 5 is housed, almost entirely, inside the cylindrical body 3 and the impeller 6 is directly interlocked on the axis of the electric motor 5 It is preferred that the impeller 6 be molded from a single piece of an appropriate plastic material to partially cover the electric motor; This eliminates any possibility of establishing contact with areas of the extractor that may be under electrical voltage, even using the test caliber required in the tests dictated by the electrical safety standard.
Puede observarse que el cuerpo cilindrico 3 consta de dos alojamientos invertidos, uno para el electromotor anteriormente citado y otro en la parte central para dar cabida a los diferentes circuitos electrónicos, tales como el circuito temporizador y el circuito 7 dotado de un sensor de humedad (Fig. 1 ). Asimismo este alojamiento permite fijar una regleta de conexión normalizada en el supuesto de un extractor estándar, o fijar los circuitos electrónicos de una manera rápida y segura manteniéndolos sujetos por unas uñas flexibles en el interior del alojamiento, lo que aporta la ventaja de permitir alojar todas las conexiones a efectuar en su instalación sin ocupar espacio en la zona exterior y permitiendo el uso de una tapa 8 exageradamente plana, donde aporta una innovación en el tamaño de los extractores hasta ahora comercializados, permitiendo empotrar casi en su totalidad dentro de los tubos de conducción, en los agujeros u otros alojamientos realizados en los muros, ventanas o techos para esta utilización.It can be seen that the cylindrical body 3 consists of two inverted housings, one for the aforementioned electric motor and another in the central part to accommodate the different electronic circuits, such as the timer circuit and the circuit 7 equipped with a humidity sensor ( Fig. 1). Likewise, this housing allows to fix a standardized connection strip in the case of a standard extractor, or to fix the electronic circuits in a fast and safe way keeping them held by flexible nails inside the housing, which provides the advantage of allowing all the connections to be made in its installation without taking up space in the outside area and allowing the use of an exaggeratedly flat lid 8, where it brings an innovation in the size of the extractors marketed until now, allowing to embed almost entirely within the tubes of driving, in holes or other housings made in walls, windows or ceilings for this use.
Dos de los brazos radiales 4 que unen el cuerpo cilindrico 3 con la zona cilindrica 1 , situados a 180° uno del otro, presentan una bifurcación 10 del brazo 4 a fin de dar cabida a un sistema de fijación rápida a la pared del tubo de conducción, eliminando operaciones innecesarias al usuario con taladros en la pared y otros componentes utilizados como tacos de expansión y tornillos, dejando esta forma opcional por el usuario si en algún caso lo requiera, ya que la plataforma 2 tiene incorporados cuatro taladros en sus extremos para fijar con tornillos.Two of the radial arms 4 that join the cylindrical body 3 with the cylindrical zone 1, located 180 ° from each other, have a fork 10 of the arm 4 in order to accommodate a quick fixation system to the wall of the tube driving, eliminating unnecessary operations to the user with holes in the wall and other components used as expansion plugs and screws, leaving this option optional by the user if in some case requires it, since platform 2 has four drills incorporated at its ends to fix with screws.
Estas bifurcaciones definen espacios abiertos a la superficie exterior de la zona cilindrica 1 (Fig. 2) y cerrados por un tabique anterior (que en las Figs. 2 y 3 está situado en la parte alta de la correspondiente lámina de dibujo) y este tabique exterior está atravesado por un tornillo 11 ; en cada uno de estos espacios se encuentra una uña 9 que puede bascular; en su extremo libre presenta unos resaltes aptos para hincarse en superficies apropiadas y dispone de una dobladura anterior dotada de un orificio atravesable por el tornillo 9. Cada espacio comprende también una pieza 32 substancialmente prismática atravesable por el tornillo 9; esta pieza 32 está encajada sin posibilidad de giro en el espacio citado; de esta manera, al girar el tornillo 11 , la pieza 32 se mueve hacia el tabique exterior, y en consecuencia ocasiona la basculación de la uña 9 hacia el exterior del cuerpo cilindrico 3, con lo que sus extremos libres sobresalen del espacio y pueden hincarse en un cuerpo que rodee la zona cilindrica 1 , anclándose las uñas 9 en las paredes donde debe instalarse, fijando el extractor de una manera rápida y limpia.These bifurcations define spaces open to the outer surface of the cylindrical zone 1 (Fig. 2) and closed by an anterior partition (which in Figs. 2 and 3 is located at the top of the corresponding drawing sheet) and this partition exterior is pierced by a screw 11; in each of these spaces there is a nail 9 that can be tilted; at its free end it has projections suitable for driving into appropriate surfaces and has an anterior bending provided with a hole pierced by the screw 9. Each space also comprises a substantially prismatic part 32 pierced by the screw 9; this piece 32 is fitted without the possibility of turning in the space mentioned; in this way, by turning the screw 11, the piece 32 moves towards the outer partition, and consequently causes the tilting of the nail 9 towards the outside of the cylindrical body 3, whereby its free ends protrude from the space and can swell in a body that surrounds the cylindrical zone 1, the nails 9 being anchored in the walls where it should be installed, fixing the extractor in a fast and clean way.
Puede observarse que en el ejemplo de realización representado en los dibujos los brazos radiales han sido diseñados con una forma plana y delgada, de manera que actúen modestamente como directrices fijas del flujo de aire, aprovechando el máximo de la sección circular para el paso de dicho flujo, pero pudiéndolos ejecutar con otras formas y secciones.It can be seen that in the embodiment shown in the drawings the radial arms have been designed with a flat and thin shape, so that they act modestly as fixed air flow guidelines, taking full advantage of the circular section for the passage of said flow, but being able to execute them with other forms and sections.
En el cuerpo cilindrico 3 puede apreciarse una columna central 12, para atornillar la tapa de protección 13, preferentemente moldeada de una sola pieza, que puede cerrar el alojamiento de la circuiteria electrónica; preferentemente es redonda, pero puede adoptar otras configuraciones, con unos brazos dispuestos a 180° con el fin de adaptarse a los canales practicados en los brazos radiales para el paso de los cables y poder posicionar la tapa 13 con seguridad, En caso que se considere conveniente, se pueden realizar unas pequeñas ranuras 14 con lo que permite el paso de humedad para su detección sin incumplir ningún ensayo de la norma. Asimismo lleva incorporado un taladro 15, en el caso de incorporar un sensor de humedad con el fin de mostrar un diodo emisor de luz (led) para la señalización del funcionamiento.In the cylindrical body 3 a central column 12 can be seen, to screw the protective cover 13, preferably molded in one piece, which can close the housing of the electronic circuitry; preferably it is round, but it can adopt other configurations, with arms arranged at 180 ° in order to adapt to the channels made in the radial arms for the passage of the cables and to be able to position the cover 13 safely, in case it is considered Convenient, small grooves 14 can be made allowing moisture to pass through for detection without violating any standard test. It also incorporates a drill 15, in the case of incorporating a humidity sensor in order to show a light emitting diode (led) for signaling operation.
Una tapa frontal 8 puede encajar a presión y quedar fijada sobre la cara frontal de la carcasa-soporte; esto se puede realizar, por ejemplo, por medio de un dispositivo 31 de anclaje antirretorno, el cual sólo se desenclava con la ayuda de una punta de un destornillador. Esta tapa 8, preferentemente moldeada de una sola pieza, adopta la forma de una cazoleta muy plana de planta cuadrada, presentando un borde lateral 16 (Fig. 2) de muy pequeña altura dispuesto para ajusfar por su borde libre sobre el borde de la aleta 2. Dicha tapa de preferencia ligeramente convexa o abombada, provista de una amplia ventana central 17, que constituye la abertura de admisión o entrada de aire del extractor, la cual se halla cubierta por una rejilla 18, de preferencia moldeada de una sola pieza con el conjunto, enmarcada por la parte interior de la ventana 17 por un reborde 19 (Fig. 3), que queda en disposición de encajar sobre el borde libre del diámetro interior de la zona laminar 2 de la carcasa-soporte; estos elementos quedan encajados y una altura extremadamente reducida. La salida de los conductores correspondientes al circuito de alimentación del aparato puede realizarse a través de la abertura debilitada 20 prevista a tal efecto en la zona laminar o aleta plana 2, o puede efectuarse también lateralmente a través de la tapa frontal 8, provista de una muesca 21 en su pared lateral.A front cover 8 can fit under pressure and be fixed on the front face of the support housing; This can be done, for example, by means of a non-return anchoring device 31, which is only unlocked with the aid of a screwdriver tip. This cover 8, preferably molded in one piece, takes the form of a very flat square-shaped bowl, presenting a lateral edge 16 (Fig. 2) of very small height arranged to adjust by its free edge on the edge of the fin 2. Said preferably slightly convex or domed cover, provided with a large central window 17, which constitutes the intake or air inlet opening of the extractor, which is covered by a grid 18, preferably molded in one piece with the assembly, framed by the inside of the window 17 by a flange 19 (Fig. 3), which is arranged to fit over the free edge of the inner diameter of the laminar zone 2 of the support housing; these elements are fitted and an extremely reduced height. The output of the conductors corresponding to the power circuit of the apparatus can be carried out through the weakened opening 20 provided for this purpose in the laminar zone or flat fin 2, or it can also be carried out laterally through the front cover 8, provided with a Notch 21 on its side wall.
De acuerdo con una importante característica de la invención, en el extremo de la zona cilindrica 1 , existen dos ranuras de forma cuadrada para el anclaje de un primer aro 22, el cual está provisto a su vez de unas uñas para su fijación y unos taladros que atraviesan el grosor del primer aro 22 para incorporar dos aletas semicirculares 24, cuya función se destina a obturar el paso del aire de retorno, con la ayuda de dos resortes de escasa presión, insertados en el eje de giro de las aletas, dando la única posibilidad del paso del aire en dirección al exterior.According to an important feature of the invention, at the end of the cylindrical zone 1, there are two grooves of square shape for the anchoring of a first ring 22, which in turn is provided with nails for fixing and drills. that cross the thickness of the first ring 22 to incorporate two semicircular fins 24, whose function is intended to block the passage of the return air, with the help of two low pressure springs, inserted in the axis of rotation of the fins, giving the only possibility of the passage of air towards the outside.
En la superficie exterior de la zona cilindrica 1 se encuentran unos relieves entre los que se definen unos espacios dispuestos helicoidalmente: estos espacios son aptos para recibir la inserción de un resalte helicoidal practicado en la superficie cilindrica interna de un segundo aro 25 (Fig. 3), todo ello de manera que el montaje por roscado de dicho aro en dicha zona cilindrica, hace posible obtener una graduación de la distancia del segundo 25 aro con la zona laminar 2. En otras palabras, el extractor, además de a un muro o techo, puede ser aplicado a un cristal de ventana; con esta finalidad se dispone de un juego de piezas (kit) opcional compuesto del segundo 25, un marco 26, una tapa frontal 27 y un marco de compensación 28, los cuales están moldeados en material plástico. El segundo aro 25 lleva incorporado en su diámetro interior un hilo de rosca que se acopla a las secciones roscadas de la zona cilindrica 1 de la carcasa-soporte por lo cual cuando rosca en dicha zona aprisiona al marco kit 26 contra el cristal y desplazando la cara interior del soporte dejando una zona de compensación entre los dos elementos mencionados que dependerá del grosor del cristal. Es por todo lo mencionado que en ambos casos se compensa la distancia con el marco de compensación 28 que al ser encajables se puede construir la altura deseada.On the outer surface of the cylindrical zone 1 there are reliefs between which helically arranged spaces are defined: these spaces are suitable for receiving the insertion of a helical projection practiced in the internal cylindrical surface of a second ring 25 (Fig. 3), all this so that the threaded mounting of said ring in said cylindrical zone, makes it possible to obtain a graduation of the distance of the second ring with the laminar zone 2. In other words, the extractor, in addition to a wall or ceiling, can be applied to a window pane; for this purpose there is an optional set of pieces (kit) consisting of the second 25, a frame 26, a front cover 27 and a compensation frame 28, which are molded in plastic material. The second ring 25 incorporates a thread in its inner diameter that is coupled to the threaded sections of the cylindrical zone 1 of the housing-support, whereby when it threads in said area it presses the kit frame 26 against the glass and displacing the inner face of the support leaving a compensation zone between the two mentioned elements that will depend on the thickness of the glass. It is for all the reasons mentioned that in both cases the distance is compensated with the compensation frame 28 that, when fitted, the desired height can be constructed.
