DESCRIPCIONDESCRIPTION
Cabezal aspirador de aspiradoraVacuum cleaner head
La invencion se refiere a un cabezal aspirador para una aspiradora de polvo, particularmente adaptado para las aspiradoras de pequena potencia cuya armazon se encuentra integrada en un mango ngido articulado con relacion al cabezal aspirador y manipulado directamente por un operador, generalmente denominadas aspiradoras “escoba”. Tambien se refiere esta a una aspiradora de polvo como tal que comprende un cabezal aspirador de este tipo.The invention relates to a vacuum head for a dust vacuum cleaner, particularly adapted for small power vacuum cleaners whose frame is integrated in a nipple articulated handle in relation to the vacuum head and manipulated directly by an operator, generally called "broom" vacuum cleaners. . This also refers to a dust vacuum as such comprising a vacuum head of this type.
Las aspiradoras escoba, descritas, por ejemplo, por los documentos EP 1611829 y EP 0909546, comprenden un mango ngido articulado segun varios grados de libertad con relacion al cabezal aspirador asentado sobre el suelo con el fin de favorecer su manipulacion. Los cabezales aspiradores cumplen por su naturaleza una mision primordial para la eficacia de limpieza del conjunto de la aspiradora, ya que cumplen la funcion de extraer el polvo y los residuos del suelo que va a limpiarse. Para las aspiradoras escoba que funcionan con pequena potencia, para flujos entre 9 y 15 l/s, su mision es tanto mas importante cuanto que la potencia de aspiracion utilizada es pequena.The broom vacuum cleaners, described, for example, by documents EP 1611829 and EP 0909546, comprise a hinged handle articulated according to various degrees of freedom in relation to the vacuum head seated on the ground in order to favor its manipulation. The vacuum heads fulfill by their nature a primary mission for the cleaning efficiency of the vacuum cleaner assembly, since they fulfill the function of extracting dust and debris from the floor to be cleaned. For broom vacuum cleaners that operate with small power, for flows between 9 and 15 l / s, their mission is all the more important as the suction power used is small.
Por este motivo, el documento EP 1611829 describe una solucion particular en la que el cabezal aspirador de una aspiradora escoba presenta una forma sensiblemente rectangular, con una pared frontal en arco de drculo para favorecer el desplazamiento del cabezal aspirador, y una suela particularmente adaptada para la limpieza eficiente de un suelo mediante una aspiradora escoba. No obstante, tal solucion presenta el inconveniente de no poder intervenir facilmente en los rincones o las partes de diffcil acceso.For this reason, EP 1611829 describes a particular solution in which the vacuum head of a broom vacuum cleaner has a substantially rectangular shape, with a front wall in a circular arc to favor the movement of the vacuum head, and a sole particularly adapted for Efficient cleaning of a floor by a vacuum cleaner broom. However, such a solution has the disadvantage of not being able to easily intervene in corners or parts of difficult access.
En otro tipo de aspiradoras de mayor potencia, tal y como se describe por el documento EP 1488726, se conoce utilizar un cabezal aspirador con una forma triangular, que presenta aberturas laterales y una abertura frontal, con el fin de permitir el facil acceso a partes diffciles tales como esquinas y rincones, al propio tiempo que favorece el mejor rendimiento posible. Tal solucion, sin embargo, no esta adaptada espedficamente para una aspiradora escoba, y exige una gran potencia para que el polvo sea conducido desde las diferentes aberturas del cabezal aspirador hacia el conducto de aspiracion central. Ademas, aun si esta solucion preve cepillos en correspondencia con las aberturas laterales para captar mejor el polvo, esta solucion mantiene un rendimiento que puede ser mejorado.In another type of higher power vacuum cleaners, as described by EP 1488726, it is known to use a triangular shaped vacuum head, which has lateral openings and a front opening, in order to allow easy access to parts Difficult such as corners and corners, while favoring the best possible performance. Such a solution, however, is not specifically adapted for a broom vacuum, and requires great power for dust to be driven from the different openings of the vacuum head to the central suction duct. In addition, even if this solution provides brushes in correspondence with the side openings to better capture dust, this solution maintains a performance that can be improved.
El documento FR 2773317 describe un cabezal aspirador para aspiradora de forma rectangular. La suela comprende un orificio de aspiracion y un canal transversal que comunica con este orificio. Por otro lado, el canal desemboca en la periferia de la suela por unos orificios.Document FR 2773317 describes a vacuum cleaner vacuum head rectangular. The sole comprises a suction hole and a transverse channel that communicates with this hole. On the other hand, the channel flows into the periphery of the sole through holes.

Tal abertura permite conducir los diferentes flujos provenientes de los canales laterales hacia el interior del cabezal aspirador.Advantageously, the vacuum head comprises an opening in the lower surface of the sole of the vacuum head related to at least one of the channels delimited by at least one scraping rib by at least one opening provided in the rib, the surface opening being bottom of the sole of the vacuum head related to a suction duct positioned at the top of the vacuum head. Such opening allows the different flows from the lateral channels to be directed into the vacuum head.
De acuerdo con esta configuracion, la abertura de la superficie inferior de la suela del cabezal aspirador se halla ventajosamente posicionada en una zona trasera del cabezal aspirador de forma rectangular, y lleva integrado un cepillo automatico, que permite incrementar la eficacia de eliminacion del polvo de los suelos de tipo moqueta.In accordance with this configuration, the opening of the lower surface of the sole of the vacuum head is advantageously positioned in a rear area of the vacuum head in a rectangular manner, and has an automatic brush integrated, which allows to increase the dust removal efficiency of carpet type floors.
Por otro lado, consiste una mejora de tal cabezal aspirador en un orificio frontal dispuesto en correspondencia con la punta del cabezal aspirador, relacionado por un canal longitudinal bajo la suela del cabezal aspirador hacia una abertura anterior apta para conducir el polvo a una zona anterior del canal de aspiracion.On the other hand, there is an improvement of such a vacuum head in a front hole arranged in correspondence with the tip of the vacuum head, related by a longitudinal channel under the sole of the vacuum head towards an anterior opening suitable for driving the dust to an anterior area of the suction channel
Asf, tal cabezal aspirador presenta una abertura frontal que permite aspirar residuos voluminosos que son introducidos directamente en el cabezal aspirador, independientemente de los canales transversales.Thus, such a vacuum head has a front opening that allows the extraction of bulky residues that are introduced directly into the vacuum head, regardless of the transverse channels.
Ventajosamente, el cabezal aspirador comprende una suela maciza dispuesta detras de la abertura de la superficie inferior de la suela del cabezal aspirador que comprende tiras de arranque de hilos.Advantageously, the vacuum head comprises a solid sole arranged behind the opening of the bottom surface of the sole of the vacuum head comprising thread starter strips.

separacion y almacenamiento 7 de los residuos, que es amovible con el fin de poderse limpiar. Este mango 4 esta articulado segun varios grados de libertad con relacion al cabezal aspirador 2 y es manipulado directamente por el usuario como si de una escoba se tratara, con el fin de desplazar el cabezal aspirador 2 sobre el suelo que va a limpiarse.Separation and storage 7 of the waste, which is removable in order to be cleaned. This handle 4 is articulated according to various degrees of freedom in relation to the vacuum head 2 and is manipulated directly by the user as if it were a broom, in order to move the vacuum head 2 on the floor to be cleaned.
El cabezal aspirador 2 presenta una forma particular que comprende una punta 10 destinada a quedar orientada hacia adelante y una arista trasera 9 transversal en cuyo borde van montadas unas ruedecillas 11 para facilitar su avance. A los efectos de la siguiente descripcion, definimos la direccion longitudinal x como el eje de simetna horizontal del cabezal aspirador que pasa en el centro de su arista trasera 9 y por su punta 10, orientada de la parte trasera hacia la delantera. Por lo tanto, este eje x representa la direccion natural de desplazamiento del cabezal aspirador. Llamamos y al eje transversal horizontal perpendicular al eje longitudinal x. Finalmente, llamamos z a la direccion vertical orientada hacia arriba, perpendicular al plano del cabezal aspirador definido por los ejes x e y.The suction head 2 has a particular shape comprising a tip 10 intended to be oriented forward and a transverse rear edge 9 on whose edge wheels 11 are mounted to facilitate its advance. For the purposes of the following description, we define the longitudinal direction x as the horizontal symmetry axis of the vacuum head that passes in the center of its rear edge 9 and through its tip 10, oriented from the rear to the front. Therefore, this x-axis represents the natural direction of travel of the vacuum head. We call y the horizontal transverse axis perpendicular to the longitudinal axis x. Finally, we call z the vertical direction facing upwards, perpendicular to the plane of the vacuum head defined by the x and y axes.
La figura 2 permite ver desde arriba la cubierta 22 del cabezal aspirador que comprende una forma que se puede descomponer en una parte delantera triangular, que se extiende aproximadamente a lo largo de las tres cuartas partes de la longitud del cabezal aspirador, y una parte trasera de forma sensiblemente rectangular, delimitada por dos angulos delanteros 12, 13 y dos angulos traseros 14, 15, determinando la juntura entre estos ultimos la arista trasera 9. Por lo tanto, los cinco angulos 10, 12, 13, 14, 15 bastan para delimitar la geometna horizontal del cabezal aspirador.Figure 2 shows from above the cover 22 of the vacuum head comprising a shape that can be decomposed into a triangular front part, which extends approximately along three quarters of the length of the vacuum head, and a rear part substantially rectangular, delimited by two front angles 12, 13 and two rear angles 14, 15, determining the junction between the latter the rear edge 9. Therefore, the five angles 10, 12, 13, 14, 15 are enough to delimit the horizontal geometry of the vacuum head.
Por lo tanto, la parte delantera triangular del cabezal aspirador comprende dos aristas que se extienden desde la punta delantera 10 hacia respectivamente los angulos delanteros 12, 13. Un conducto de aspiracion 16 de seccion sensiblemente circular, visible en la figura 2, se extiende bajo la cubierta 22 del cabezal aspirador, desde una zona anterior 17 posicionada en una parte central de la parte triangular del cabezal aspirador hasta una zona trasera 18 posicionada en la parte trasera rectangular del cabezal aspirador. Este conducto de aspiracion 16 discurre a lo largo del eje longitudinal medio del cabezal aspirador. En su zona trasera 18, esta relacionado con un tubo flexible secundario 19, que permite relacionar este conducto primario 16 sensiblemente horizontal con el mango 4 de inclinacion variable, que puede ocupar una posicion vertical. Por lo tanto, el tubo flexible secundario 19 sirve de intermediario entre el cabezal aspirador 2 y el mango 4 y, en su parte superior 20, comprende una zona de vinculacion destinada a recibir el mango ngido 4 de la aspiradora escoba.Therefore, the triangular front part of the vacuum head comprises two edges extending from the front tip 10 towards respectively the front angles 12, 13. A suction duct 16 of substantially circular section, visible in Figure 2, extends under the cover 22 of the vacuum head, from a front area 17 positioned in a central part of the triangular part of the vacuum head to a rear area 18 positioned in the rectangular rear part of the vacuum head. This suction duct 16 runs along the middle longitudinal axis of the vacuum head. In its rear area 18, it is related to a secondary flexible tube 19, which makes it possible to relate this substantially horizontal primary conduit 16 with the variable inclination handle 4, which can occupy a vertical position. Therefore, the secondary flexible tube 19 serves as an intermediary between the suction head 2 and the handle 4 and, in its upper part 20, comprises a bonding area intended to receive the nipple handle 4 of the broom vacuum.
La invencion trata particularmente de la geometna de la suela 21 del cabezal aspirador 2, visible en la figura 4, que esta directamente destinada a atraer el polvo y los residuos desde el suelo hasta el interior del conducto primario 16 del cabezal aspirador, antes de llegar al conducto del mango 4 de la aspiradora para, finalmente, quedar retenidos dentro del dispositivo de separacion y almacenamiento 7.The invention particularly concerns the sole geometry 21 of the vacuum head 2, visible in Figure 4, which is directly intended to attract dust and debris from the floor to the interior of the primary duct 16 of the vacuum head, before arriving to the conduit of the handle 4 of the vacuum cleaner to finally be retained within the separation and storage device 7.
La geometna de la suela 21 del cabezal aspirador permite dos tipos de aspiracion, segun la forma de ejecucion escogida.The sole geometry 21 of the vacuum head allows two types of aspiration, according to the chosen embodiment.
El primer tipo de aspiracion radica en un orificio frontal vertical 25 previsto en el reborde vertical frontal de la suela del cabezal aspirador, en correspondencia con su punta 10, tal como queda particularmente visible en la figura 3. Este orificio 25 presenta unas considerables dimensiones para permitir aspirar residuos o polvo grueso sin mas que acercar la punta 10 del cabezal aspirador a su proximidad.The first type of aspiration lies in a vertical front hole 25 provided in the front vertical flange of the sole of the vacuum head, in correspondence with its tip 10, as is particularly visible in Figure 3. This hole 25 has considerable dimensions for allow to vacuum debris or coarse dust by simply bringing the tip 10 of the vacuum head close to it.
El orificio 25 conduce hacia un canal anterior longitudinal 26 de escasa longitud, acondicionado en la suela del cabezal aspirador, que desde arriba desemboca en la zona anterior 17 del conducto de aspiracion 16. Este canal anterior 26 es un canal abierto hacia abajo, determinado por una porcion horadada de la suela del cabezal aspirador. Un flujo de aire lo recorre a gran velocidad arrastrando los residuos desde el suelo hacia el conducto de aspiracion 16, que se halla dispuesto en la parte alta del cabezal aspirador y que es un conducto tubular, a excepcion de unas aberturas de vinculacion 67, 68.The hole 25 leads to a longitudinal anterior channel 26 of short length, conditioned in the sole of the vacuum head, which from the top leads to the anterior zone 17 of the suction duct 16. This anterior channel 26 is an open channel downwards, determined by a perforated portion of the sole of the vacuum head. A flow of air travels at high speed by dragging the debris from the ground to the suction duct 16, which is arranged in the upper part of the suction head and is a tubular duct, except for connection openings 67, 68 .
La juntura entre este canal abierto anterior 26 y el conducto de aspiracion tubular 16 del cabezal aspirador se realiza por mediacion de la abertura delantera 33 de la suela del cabezal aspirador, sensiblemente vertical, particularmente visible en la figura 7, acondicionada entre una placa sensiblemente horizontal 28 determinante de una superficie inferior maciza de la suela, en correspondencia con la parte triangular del cabezal aspirador, y la pared superior del conducto 16.The joint between this anterior open channel 26 and the tubular suction duct 16 of the vacuum head is made by means of the front opening 33 of the sole of the suction head, substantially vertical, particularly visible in Figure 7, arranged between a substantially horizontal plate 28 determining a solid bottom surface of the sole, in correspondence with the triangular part of the vacuum head, and the upper wall of the duct 16.
Esta placa 28 presenta una forma triangular cuya punta 29 esta posicionada frente al orificio 25 y cuyas aristas, que se extienden hacia atras, son paralelas a las aristas de la parte triangular del cabezal aspirador. La abertura vertical 33, delimitada por esta placa, se extiende desde la punta 29 hasta dos puntos 30, 31, posicionados en la parte delantera de estas aristas.This plate 28 has a triangular shape whose tip 29 is positioned in front of the hole 25 and whose edges, which extend backwards, are parallel to the edges of the triangular part of the vacuum head. The vertical opening 33, delimited by this plate, extends from tip 29 to two points 30, 31, positioned at the front of these edges.
El distanciamiento entre estos puntos traseros 30, 31 que delimitan la abertura 33 de juntura con el conducto de aspiracion 16 permite garantizar que los residuos que son aspirados por el orificio frontal 25 no puedan escapar a su entrada en la parte anterior 17 del conducto de aspiracion 16. Como observacion, bajo la placa triangular 28, estan acondicionadas dos ruedas pequenas 32 para facilitar el desplazamiento del cabezal aspirador.The spacing between these rear points 30, 31 that delimit the joint opening 33 with the suction duct 16 makes it possible to ensure that the debris that is aspirated by the front hole 25 cannot escape its entry into the front part 17 of the suction duct 16. As an observation, under the triangular plate 28, two small wheels 32 are arranged to facilitate the movement of the vacuum head.

El segundo tipo de aspiracion radica en unos orificios laterales 35 acondicionados en el seno de las dos aristas laterales de la parte triangular anterior del cabezal aspirador, visible particularmente en la figura 6. De acuerdo con la forma de ejecucion escogida, sobre cada una de estas aristas estan previstos cuatro orificios laterales 35, 35'. Estos orificios 35, 35' conducen todos ellos hacia un canal superficial abierto 36 que discurre, paralelamente a las aristas laterales del cabezal aspirador, desde los angulos 12, 13 de estas aristas, en correspondencia con los cuales estan posicionados los orificios laterales 35' mas retrasados, hasta el canal anterior 26 proximo a la punta 10 del cabezal aspirador.The second type of aspiration lies in lateral holes 35 fitted within the two lateral edges of the front triangular part of the vacuum head, particularly visible in Figure 6. According to the chosen embodiment, on each of these edges are provided four side holes 35, 35 '. These holes 35, 35 'all lead to an open surface channel 36 that runs parallel to the side edges of the vacuum head, from angles 12, 13 of these edges, in correspondence with which the side holes 35' are positioned more delayed, to the previous channel 26 near the tip 10 of the vacuum head.
Sobre cada una de estas aristas laterales del cabezal aspirador, el orificio 35 mas adelantado se encuentra en correspondencia con la parte trasera de la abertura frontal 33, en correspondencia con los extremos traseros 30, 31 de esta abertura. Finalmente, otros dos orificios laterales se hallan dispuestos alrededor de la zona central de estas aristas, con el fin de obtener una distribucion bastante homogenea de estos orificios laterales, visible en las figuras 4 y 5, y permitir las mayores posibilidades de aspiracion del polvo pequeno posicionado en las inmediaciones del cabezal aspirador.On each of these lateral edges of the vacuum head, the most advanced hole 35 is in correspondence with the rear part of the front opening 33, in correspondence with the rear ends 30, 31 of this opening. Finally, two other lateral holes are arranged around the central area of these edges, in order to obtain a fairly homogeneous distribution of these lateral holes, visible in Figures 4 and 5, and allow the greatest possibilities of aspiration of small dust positioned near the vacuum head.
Por detras de la placa triangular 28 del cabezal aspirador discurren cuatro canales transversales 37 abiertos, acondicionados mediante relieves en la superficie inferior de la suela del cabezal aspirador. Estos canales 37 estan delimitados por cuatro nervaduras transversales 38, 38'. Cada canal transversal relaciona entre ellos los dos canales laterales 36, segun una juntura redondeada que favorece el viraje en angulo agudo de los flujos de aire provenientes de estos canales laterales 36 hacia los canales transversales 37.Behind the triangular plate 28 of the vacuum head there are four open transverse channels 37, conditioned by reliefs on the bottom surface of the sole of the vacuum head. These channels 37 are delimited by four transverse ribs 38, 38 '. Each transverse channel relates the two lateral channels 36 to each other, according to a rounded joint that favors the sharp angle of air flows from these lateral channels 36 towards the transverse channels 37.
Las tres nervaduras transversales 38 mas adelantadas se hallan interrumpidas en su parte central para el paso de un canal central longitudinal 39. La nervadura 38' mas retrasada comprende cinco aberturas 41, entre ellas, una abertura central alineada con el canal central longitudinal 39.The three most advanced transverse ribs 38 are interrupted in their central part for the passage of a longitudinal central channel 39. The most delayed rib 38 'comprises five openings 41, including a central opening aligned with the longitudinal central channel 39.
Inmediatamente detras de esta ultima nervadura 38', se encuentra una abertura horizontal rectangular 40 que se extiende en el seno de una placa trasera 42 que define, en la parte trasera del cabezal aspirador, una parte maciza sensiblemente horizontal que facilita su desplazamiento. Esta placa maciza 42 ocupa sensiblemente la superficie trasera rectangular del cabezal aspirador.Immediately behind this last rib 38 ', there is a rectangular horizontal opening 40 that extends into a rear plate 42 which defines, at the rear of the vacuum head, a substantially horizontal solid part that facilitates its movement. This solid plate 42 substantially occupies the rectangular rear surface of the vacuum head.
Las nervaduras transversales 38, 38', que son perpendiculares al sentido de desplazamiento del cabezal aspirador, tienen como funcion no solo delimitar los canales transversales 37, sino tambien poder raspar un suelo recubierto, por ejemplo, con una moqueta, con el fin de poder levantar el polvo y otros residuos que en el se encuentren para facilitar su aspiracion por los diferentes canales abiertos dispuestos en el seno de la suela del cabezal aspirador. Por lo tanto, estas cumplen una segunda funcion tecnica de arranque de hilos y/o levantapolvo, y tienen, para ello, una dimension suficiente, especialmente una extension hacia abajo que les permite aproximarse en modo suficiente al suelo.The transverse ribs 38, 38 ', which are perpendicular to the direction of travel of the vacuum head, have the function not only to delineate the transverse channels 37, but also to be able to scrape a floor covered, for example, with a carpet, in order to be able to lift the dust and other residues that are in it to facilitate its aspiration through the different open channels arranged in the sole of the sole of the vacuum head. Therefore, these fulfill a second technical function of thread starter and / or dust lifter, and have, for this, a sufficient dimension, especially a downward extension that allows them to approach the ground sufficiently.
Como variante, estas nervaduras 38, 38' podnan presentar otra forma, otra orientacion ligeramente inclinada con respecto al eje transversal y, de mas o menos 30 grados, por ejemplo, o de manera mas general, presentando una componente transversal perpendicular al sentido de desplazamiento del cabezal aspirador. El numero de estas nervaduras tambien puede variar. Estas nervaduras 38, 38' podnan encontrarse en otra ubicacion que no sea la relativamente centrada de la forma de ejecucion ilustrada.As a variant, these ribs 38, 38 'may have another shape, another orientation slightly inclined with respect to the transverse axis and, more or less 30 degrees, for example, or more generally, presenting a transverse component perpendicular to the direction of travel of the vacuum head. The number of these ribs may also vary. These ribs 38, 38 'could be found in a location other than the relatively centered one of the illustrated embodiment.
Esta doble funcion que cumplen las nervaduras 38, 38', de delimitacion de un canal de corriente 37 y de raspado del suelo, presenta la ventaja de reducir la ocupacion de espacio bajo la superficie inferior del cabezal aspirador.This double function of the ribs 38, 38 ', of delimiting a current channel 37 and scraping the floor, has the advantage of reducing the occupation of space under the lower surface of the vacuum head.
En el seno de la abertura rectangular 40, se halla dispuesto un cepillo automatico 43, puesto en movimiento por un motor electrico 46. Este cepillo electrico permite levantar el polvo, los hilos o residuos sobre una moqueta, etc., para aspirarlos mejor. Finalmente, en la parte trasera de la placa 42 del cabezal aspirador se hallan dispuestas unas zonas ranuradas o tiras de arranque de hilos 44 destinadas a favorecer el levantamiento del polvo y especialmente de las fibras.Within the rectangular opening 40, an automatic brush 43 is arranged, set in motion by an electric motor 46. This electric brush allows the dust, threads or debris to be lifted on a carpet, etc., to better aspirate them. Finally, grooved areas or strips of strips 44 are arranged at the rear of the plate 42 of the vacuum head, designed to favor the removal of dust and especially fibers.
La abertura horizontal 40 de la suela del cabezal aspirador desemboca en un conducto conico convergente hacia el conducto de aspiracion 16 del cabezal aspirador, en correspondencia con su zona trasera 18. Un deflector 45, particularmente visible en la figura 7, permite orientar el flujo entrante por esta abertura trasera 40 de manera paralela al eje del conducto de aspiracion 16, para evitar cualquier colision con el flujo proveniente de la abertura delantera 33, desde la parte anterior 17 del conducto de aspiracion 16, generado por el primer tipo de aspiracion.The horizontal opening 40 of the sole of the vacuum head flows into a conical duct converging towards the suction duct 16 of the vacuum head, in correspondence with its rear zone 18. A deflector 45, particularly visible in Figure 7, allows the incoming flow to be oriented by this rear opening 40 parallel to the axis of the suction duct 16, to avoid any collision with the flow from the front opening 33, from the front part 17 of the suction duct 16, generated by the first type of aspiration.
Esta particular geometna del cabezal aspirador permite conseguir el funcionamiento ventajoso que se describe a continuacion. Los orificios laterales 35 de la parte triangular del cabezal aspirador, de menor dimension que el orificio frontal 25, permiten la aspiracion del polvo situado en las inmediaciones del cabezal aspirador, no directamente situado en el trayecto de la punta 10 del cabezal aspirador. Tras su entrada por estos orificios, el polvo es arrastrado por un flujo de aspiracion que recorre, primero, los canales laterales superficiales 36 y, luego, los canales transversales 37. Finalmente, estos flujos convergen hacia la abertura horizontal trasera 40, por una de las aberturas 41 de la ultima nervadura 38', ocasionalmente por el canal longitudinal central 39, para ascender al conducto de aspiracion tubular 16 y luego al mango 4.This particular geometry of the vacuum head allows to achieve the advantageous operation described below. The side holes 35 of the triangular part of the vacuum head, smaller in size than the front hole 25, allow the aspiration of the dust located in the vicinity of the vacuum head, not directly located in the path of the tip 10 of the vacuum head. Upon entry through these holes, the dust is carried by a suction flow that runs, first, the surface lateral channels 36 and then the transverse channels 37. Finally, these flows converge towards the rear horizontal opening 40, by one of the openings 41 of the last rib 38 ', occasionally through the central longitudinal channel 39, to ascend to the tubular suction duct 16 and then to the handle 4.
Los diferentes canales que reciben las corrientes de aspiracion desde los orificios laterales 35 hasta la abertura trasera 40 tienen una geometna tal que su seccion de paso va disminuyendo, al efecto de inducir una aceleracion de estas corrientes y favorecer el arrastre de todo el polvo y/o los residuos.The different channels that receive the suction currents from the side holes 35 to the rear opening 40 have a geometry such that their passage section is decreasing, in order to induce an acceleration of these currents and favor the drag of all the dust and / or waste
La invencion se ha ilustrado en el supuesto de una geometna particular del cabezal aspirador de la aspiradora 5 escoba a tftulo no limitativo. Como variante, este cabezal aspirador puede presentar, por ejemplo, una forma completamente triangular, e incluso una forma en la que la parte rectangular es dominante, e incluso una forma sensiblemente rectangular. Ademas, los diferentes canales abiertos hacia abajo, ahuecados bajo la superficie inferior de la suela podnan presentar, sin salir del ambito de la invencion, otras formas mediante cualquier tipo de relieve, otros numeros. Por ejemplo, podna haber un solo canal transversal 37 delimitado por una sola nervadura 10 transversal 38 de raspado.The invention has been illustrated in the case of a particular geometry of the vacuum head of the vacuum cleaner 5 broom on a non-limiting basis. As a variant, this vacuum head may, for example, have a completely triangular shape, and even a shape in which the rectangular part is dominant, and even a substantially rectangular shape. In addition, the different channels open downward, hollowed under the bottom surface of the sole may present, without leaving the scope of the invention, other forms by any type of relief, other numbers. For example, there could be a single transverse channel 37 delimited by a single transverse rib 10 of scraping 38.
Ademas, la invencion se ha ilustrado en el ambito de una implementacion con dos tipos de aspiracion por dos orificios diferentes conducentes al mismo conducto de aspiracion. No obstante, esta podna verse simplificada en una variante, no representada, con un solo orificio de aspiracion, suprimiendose, por ejemplo, el orificio frontal.In addition, the invention has been illustrated in the field of an implementation with two types of aspiration through two different holes leading to the same aspiration duct. However, this could be simplified in a variant, not shown, with a single suction hole, removing, for example, the front hole.
Ademas, el cabezal aspirador de la invencion, aun si esta particularmente adaptado para una utilizacion en una 15 aspiradora escoba, tambien podna ser adecuado para cualquier otra utilizacion en cualquier tipo de aspiradora.In addition, the vacuum head of the invention, even if it is particularly adapted for use in a broom vacuum cleaner, may also be suitable for any other use in any type of vacuum cleaner.
Por ultimo, la solucion descrita logra asf los objetos perseguidos y presenta las siguientes ventajas:Finally, the solution described thus achieves the objects pursued and has the following advantages:
- la aspiradora sigue siendo muy manejable y de facil empleo, ya que su mango conserva toda su movilidad y el cabezal aspirador presenta una forma y unos orificios de aspiracion que le permiten alcanzar zonas poco accesibles tales como rincones;- the vacuum cleaner is still very manageable and easy to use, since its handle retains all its mobility and the vacuum head has a shape and suction holes that allow it to reach areas that are not accessible such as corners;
20 - la suela del cabezal aspirador es particularmente eficaz para el levantamiento de polvo y residuos20 - the sole of the vacuum head is particularly effective for the removal of dust and debris
prendidos, por ejemplo, en una moqueta o una alfombra;lit, for example, on a carpet or carpet;
- la suela del cabezal aspirador presenta canales de formas que permiten la conduccion eficiente de un maximo de residuos hacia el conducto de aspiracion por una de las dos aberturas.- The sole of the vacuum head has channels in ways that allow the efficient conduction of a maximum of waste to the aspiration duct through one of the two openings.
