La boquilla esta conectada al cuerpo de la aspiradora por mediacion de un tubo de vinculacion. La aspiradora cuenta especialmente con un motoventilador capacitado para crear un flujo de aspiracion de aire dentro del tubo y dentro de la boquilla.The nozzle is connected to the vacuum body by means of a connecting tube. The vacuum especially has a motorized fan capable of creating a flow of air aspiration inside the tube and inside the nozzle.
La boquilla incluye tres componentes principales: una suela 2, un cepillo 3 y una cubierta superior 1. El cepillo 3 y la cubierta 1 se ensamblan sobre la suela 2 para determinar la boquilla de la aspiradora.The nozzle includes three main components: a sole 2, a brush 3 and an upper cover 1. The brush 3 and the cover 1 are assembled on the sole 2 to determine the nozzle of the vacuum cleaner.
La suela 2 comprende un marco 20 sensiblemente rectangular. El espesor del marco es del orden de unos milfmetros, mientras que la altura es del orden de algunas decenas de milfmetros. El marco 20 esta realizado, por ejemplo, en material plastico.The sole 2 comprises a substantially rectangular frame 20. The thickness of the frame is of the order of a few millimeters, while the height is of the order of a few tens of millimeters. The frame 20 is made, for example, in plastic material.
El marco 20 comprende medios de fijacion 23, 24 que permiten el ensamble del cepillo 3. A tttulo de ejemplo, los medios de fijacion 23, 24 comprenden escotaduras sobre la cara exterior del marco 20. El cepillo 3 queda inserto a presion dentro de estas escotaduras 23, 24. Se pueden prever otros medios de ensamble del cepillo 3 sobre el marco 20. De este modo, el cepillo 3 puede ir pegado y/o anclado elasticamente sobre el marco 20.The frame 20 comprises fixing means 23, 24 which allow the assembly of the brush 3. By way of example, the fixing means 23, 24 comprise recesses on the outer face of the frame 20. The brush 3 is inserted under pressure within these recesses 23, 24. Other means for assembling the brush 3 can be provided on the frame 20. In this way, the brush 3 can be glued and / or elastically anchored on the frame 20.
El centro del marco 20 determina la entrada del canal de aspiracion 29 de la boquilla. Para orientar el flujo de aire cargado con residuos hacia el tubo flexible de la aspiradora, el marco 20 comprende paredes deflectoras 22. Las paredes deflectoras 22 dirigen el flujo de aire de las partes laterales de la suela 2 hacia el centro de la boquilla. Las paredes deflectoras 22 estan determinadas por planos inclinados cuya anchura se corresponde con la anchura del marco 20.The center of the frame 20 determines the intake of the suction channel 29 of the nozzle. To orient the flow of air laden with debris towards the vacuum tube of the vacuum cleaner, the frame 20 comprises deflector walls 22. The deflector walls 22 direct the air flow from the side parts of the sole 2 towards the center of the nozzle. The baffle walls 22 are determined by inclined planes whose width corresponds to the width of the frame 20.
Por otro lado, la suela 2 comprende una zona 21 de union al tubo de vinculacion de la aspiradora (no representado). La zona de union 21 esta situada sensiblemente en el centro de la boquilla y comprende paredes laterales 25 y un fondo 26. Las paredes laterales 25 estan conectadas a las paredes deflectoras 22, mientras que el fondo 26 esta conectado al marco 20 de la suela 2.On the other hand, the sole 2 comprises a zone 21 of connection to the connection tube of the vacuum cleaner (not shown). The joining area 21 is located substantially in the center of the nozzle and comprises side walls 25 and a bottom 26. The side walls 25 are connected to the deflector walls 22, while the bottom 26 is connected to the frame 20 of the sole 2 .
Segun la invencion, las paredes laterales 25 son de forma curvada y su radio de curvatura es superior a 30 mm. Esta curvatura permite limitar la formacion de turbulencia en la corriente del flujo de aire y, por tanto, disminuir el nivel de ruido. Por otro lado, las zonas de vinculacion entre el fondo 26 y las paredes laterales 25 tambien determinan superficies curvas cuyos radios de curvatura son, asimismo, superiores a 30 mm.According to the invention, the side walls 25 are curved and their radius of curvature is greater than 30 mm. This curvature makes it possible to limit the formation of turbulence in the air flow current and, therefore, to reduce the noise level. On the other hand, the areas of connection between the bottom 26 and the side walls 25 also determine curved surfaces whose radii of curvature are also greater than 30 mm.
Igualmente, las zonas de vinculacion entre las paredes inclinadas 22 y el marco 20 tienen grandes radios de curvatura (del orden de una decena de milfmetros).Similarly, the areas of connection between the inclined walls 22 and the frame 20 have large radii of curvature (of the order of a dozen millimeters).
La cubierta superior 1 es sensiblemente rectangular para fijarse al marco 20 de la suela 2. La parte central 14 de la cubierta superior 1 constituye la zona de union del tubo de la aspiradora. El tubo esta conectado a un manguito cilmdrico 10 que determina la salida aguas arriba de la zona de union. La zona de union de la cubierta superior 1 comprende una zona 13 en configuracion de tapa y unas paredes laterales 11. Las paredes laterales 11 de la cubierta superior 1 tienen sensiblemente la misma forma y, en especial, sensiblemente el mismo radio de curvatura, que las paredes laterales 25 de la suela 2. En el ensamble de la boquilla, estas se encajan unas en otras.The upper cover 1 is substantially rectangular to be fixed to the frame 20 of the sole 2. The central part 14 of the upper cover 1 constitutes the junction zone of the vacuum tube. The tube is connected to a cylindrical sleeve 10 that determines the outlet upstream of the junction zone. The joining area of the upper cover 1 comprises a zone 13 in a cover configuration and side walls 11. The side walls 11 of the upper cover 1 have substantially the same shape and, especially, substantially the same radius of curvature, which the side walls 25 of the sole 2. In the nozzle assembly, these fit into each other.
Igualmente, la zona 13 en configuracion de tapa cierra la pared superior de la zona de union 21 de la suela 2. La zona 13 en configuracion de tapa puede comprender dos nervios 15.1, 15.2 que determinan una V cuya punta esta dirigida hacia el manguito cilmdrico 10. La zona 16 situada entre los dos nervios 15.1, 15.2 es sensiblemente plana. De este modo, los flujos de aire procedentes de los lados de la boquilla y desviados por las paredes deflectoras 22 son guiados por los nervios 15.1, 15.2 al interior del tubo de aspiracion. Este guiamiento reduce las turbulencias y, por tanto, los ruidos de corriente.Likewise, the zone 13 in cover configuration closes the upper wall of the joint zone 21 of the sole 2. The zone 13 in cover configuration can comprise two ribs 15.1, 15.2 that determine a V whose tip is directed towards the cylindrical sleeve 10. Zone 16 located between the two ribs 15.1, 15.2 is substantially flat. Thus, the air flows from the sides of the nozzle and deflected by the deflector walls 22 are guided by the ribs 15.1, 15.2 into the suction tube. This guidance reduces turbulence and, therefore, current noises.
Los extremos laterales 12 de la cubierta superior 1, situados a uno y otro lado de la zona de union, son sensiblemente planos. La cubierta superior 1 comprende un reborde que, en el montaje de la boquilla, queda recubriendo en parte el marco 20 de la suela 2.The lateral ends 12 of the upper cover 1, located on either side of the junction zone, are substantially flat. The upper cover 1 comprises a flange which, in the assembly of the nozzle, is partially covering the frame 20 of the sole 2.
Segun la variante de realizacion representada en las figuras, la cubierta superior 1 esta insertada a presion sobre el borde superior del marco 20. El ensamble se puede completar con un pegado.According to the embodiment variant shown in the figures, the upper cover 1 is inserted under pressure on the upper edge of the frame 20. The assembly can be completed with a glue.
El cepillo 3 esta determinado a partir de una masa de cerdas. La forma del cepillo 3 es rectangular. De este modo, todo el penmetro de la suela 3 de la boquilla comprende cerdas.Brush 3 is determined from a mass of bristles. The shape of the brush 3 is rectangular. Thus, the entire penimeter of the sole 3 of the nozzle comprises bristles.
Las dimensiones del cepillo 3 son sensiblemente las mismas que el marco 20 de la suela 2 de la boquilla. Por otro lado, el espesor del cepillo 3, es decir, el espesor de la masa de cerdas, es del orden de unos milfmetros. La altura del cepillo, es decir, la altura de las cerdas, es del orden de una decena de milfmetros. Una vez ensamblada sobre la suela 2, la boquilla descansa sobre las cerdas del cepillo 3. Segun la invencion, el borde inferior 34 de la cara anterior del cepillo 3 lleva practicada al menos una abertura 36. De este modo, tres de los cuatro bordes del cepillo 3 no comprenden ninguna abertura. Esta configuracion permite aumentar la eficacia de aspiracion de la boquilla al controlar de manera precisa la seccion de fuga de la boquilla. En efecto, el hecho de colocar un cepillo en todo el penmetro de la suela permite garantizar la hermeticidad de la boquilla y, por tanto, la eficacia de aspiracion de la misma. La o las aberturas 36 crean una seccion de fuga para facilitar el desplazamiento de la boquilla sobre el sueloThe dimensions of the brush 3 are substantially the same as the frame 20 of the sole 2 of the nozzle. On the other hand, the thickness of the brush 3, that is, the thickness of the bristle mass, is of the order of a few millimeters. The height of the brush, that is, the height of the bristles, is of the order of a dozen millimeters. Once assembled on the sole 2, the nozzle rests on the bristles of the brush 3. According to the invention, the lower edge 34 of the front face of the brush 3 has at least one opening 36 made. Thus, three of the four edges of the brush 3 do not comprise any opening. This configuration allows to increase the suction efficiency of the nozzle by precisely controlling the leakage section of the nozzle. In fact, the fact of placing a brush on the entire penimeter of the sole allows to guarantee the tightness of the nozzle and, therefore, the aspiration efficiency thereof. The opening (s) 36 creates a leakage section to facilitate the movement of the nozzle on the floor
33
que va a limpiarse. La dimension de las aberturas se determina en funcion de un compromiso nivel de ruido / caudal de la boquilla.It is going to be cleaned. The size of the openings is determined based on a noise level / nozzle level compromise.
A tftulo de ejemplo, cuando la aspiradora funciona con un caudal aproximado de 25 L/s, la superficie total de las aberturas de los agujeros es de 550 mm2.As an example, when the vacuum works at an approximate flow of 25 L / s, the total surface of the hole openings is 550 mm2.
5 Segun la variante de realizacion representada en las figuras, la cara anterior 31 del cepillo 3 comprende una pluralidad de aberturas 36 rectangulares uniformemente distribuidas en el borde inferior 34. Esta distribucion homogenea de las aberturas 36 permite simplificar la fabricacion. Sin embargo, es posible contemplar otras configuraciones. De este modo, al tiempo que se conserva una distribucion homogenea de las aberturas 36 en el borde inferior 34 del cepillo 3, las aberturas 36 pueden ser de diferentes dimensiones. Segun un ejemplo de 10 realizacion, las aberturas 36 situadas mas al centro tienen una superficie menor que las aberturas situadas en los extremos. La superficie de las aberturas tambien puede ir aumentando progresivamente segun se alejan del plano transversal central de la boquilla. De este modo, el caudal de aspiracion a traves de las aberturas 36 es mas equilibrado.5 According to the embodiment variant shown in the figures, the front face 31 of the brush 3 comprises a plurality of rectangular openings 36 uniformly distributed on the lower edge 34. This homogeneous distribution of the openings 36 allows manufacturing to be simplified. However, it is possible to contemplate other configurations. Thus, while maintaining a homogeneous distribution of the openings 36 at the lower edge 34 of the brush 3, the openings 36 can be of different dimensions. According to an example of an embodiment, the openings 36 located more centrally have a smaller surface area than the openings located at the ends. The surface of the openings may also increase progressively as they move away from the central transverse plane of the nozzle. Thus, the suction flow through the openings 36 is more balanced.
Tambien puede variar la forma de las aberturas. Se pueden realizar aberturas en arco de cfrculo o en triangulo, en 15 lugar de las aberturas rectangulares.The shape of the openings may also vary. Openings can be made in the arc of a circle or in a triangle, instead of the rectangular openings.
La utilizacion de paredes curvadas con gran radio de curvatura para realizar en especial la zona de union de la boquilla permite, por una parte, disminuir las turbulencias y, por otra, reducir las perdidas de carga. De este modo, no solo se reducen los ruidos de corriente del aire por la boquilla, sino que tambien, para un mismo caudal, se aumenta la eficacia de aspiracion.The use of curved walls with a large radius of curvature to perform especially the nozzle junction zone allows, on the one hand, to reduce turbulence and, on the other, reduce load losses. In this way, not only the current noises of the air through the nozzle are reduced, but also, for the same flow rate, the suction efficiency is increased.
20 Al mejorar la hermeticidad de la boquilla mediante la utilizacion de un cepillo en todo el penmetro de la boquilla, por una parte, y al controlar de manera precisa, por otra parte, el caudal de fuga, se mejora la eficacia de aspiracion. Esto permite, asf, reducir el caudal de aspiracion sin rebajar las prestaciones de la boquilla. Esta reduccion del caudal reduce asimismo el nivel de ruido de la boquilla.20 By improving the tightness of the nozzle by using a brush on the entire penimeter of the nozzle, on the one hand, and by precisely controlling, on the other hand, the leakage rate, the suction efficiency is improved. This allows, thus, to reduce the flow of aspiration without reducing the performance of the nozzle. This reduction in flow also reduces the noise level of the nozzle.
