Abstract

The invention relates to a hand drying device. The inventive device is of the type that comprises a motor-actuated turbine. According to the invention, the device draws in ambient air through the turbine, conveys said air through a volute and, subsequently, releases same at a greater speed through an outlet. The air inlet zone (2) of the aforementioned volute (1) houses the motor/turbine group (3). The invention is characterised in that the volute has a spiral configuration (7) which begins at the start point (6) thereof and which encircles the centrifugal impeller (4) of the turbine, the section thereof increasing gradually until the spiral connects with the outlet (8). The aforementioned outlet narrows progressively (11) and terminates in the air outlet (12). In this way, the dimensions and power consumption of the device are reduced considerably and the dynamic fluid performance properties are used to the full.

Description

Dispositivo seca-manos.Hand-dry device
OBJETO DE LA INVENCIÓN La presente invención tiene por objeto un dispositivo secador de manos de dimensiones reducidas . CAMPO DE LA INVENCIÓN Este dispositivo es del tipo que comprende una turbina que, accionada por un motor, aspira aire ambiente haciéndolo pasar por un recinto o voluta seguido de un conducto de aire que lo expele a gran velocidad a través de una boca de salida. El dispositivo ha sido pensado principalmente para su aplicación como secador de manos de los que se instalan en los lavabos de muchas empresas y en los de muchos establecimientos públicos, y que irá montado, como los ya existentes, en un conveniente cuerpo constituido por una base y una cubierta, pudiendo conformar la base una monopieza con la voluta o parte de la misma. ANTECEDENTES DE LA INVENCIÓN Los dispositivos conocidos de dicho tipo comprenden generalmente un motor de una cierta potencia para aspirar y expeler la cantidad de aire que sea suficiente para cumplir con su objetivo, produciendo dicho motor un determinado consumo, siendo asimismo de un determinado tamaño que repercute en el tamaño global del dispositivo, habiéndose de recurrir, en general, a configuraciones complejas que con el objeto de reducir dicho tamaño penalizan las prestaciones del mismo. SUMARIO DE LA INVENCIÓN Con el dispositivo objeto de la presente invención, se consigue el máximo aprovechamiento en cuanto a prestaciones fluido-dinámicas, partiendo de unas dimensiones y un consumo reducidos, disponiendo el motor en la entrada de aire de manera que la propia aspiración favorezca la refrigeración del mismo y caracterizándose principalmente dicho dispositivo por la configuración de la voluta en espiral por el lado de admisión, posibilitando la entrada de aire a pesar de las dimensiones reducidas y la ubicación del grupo motor-turbina en la zona de admisión de dicho aire. Dicha configuración en espiral representa un aumento progresivo del tamaño de la sección de dicha voluta desde su inicio y rodea el rodete centrifugo constitutivo de la turbina hasta conectarse con el conducto de salida de aire, el cual es de sección constante hasta rematarse con un estrangulamiento progresivo que finaliza con la boca de salida de dicho aire . Esta boca de salida es de menor sección que el conducto del que procede, conformándose la canalización mediante un estrangulamiento suave y progresivo, sin cambios bruscos o angulosos de la sección que atraviesa el aire . Ventajosamente, el conducto de salida del aire está constituido por un tramo que es prolongación de la voluta y cuyo interior conforma, en la parte de sección constante, una cámara en la que está montada una resistencia calefactora para que el aire expelido por el dispositivo sea caliente, minimizando esta cámara el bloqueo del aire saliente debido a la incorporación de dicha resistencia y haciendo mínimas las perdidas de presión. Tras la finalización del tramo de sección constante o 'cámara' se hallan dispuestos unos nervios directrices que constituyen la rejilla, interpuesta entre la resistencia calefactora y el estrangulamiento del conducto de salida, cuya progresiva disminución de sección permite la canalización progresiva del aire y la concentración del mismo, incrementándose su velocidad y obteniéndose, en la boca de salida, un flujo de aire concentrado y veloz . Estas y otras características se desprenderán mejor de la descripción detallada que sigue, la cual, para facilitar su comprensión, se acompaña de una lámina de dibujos en la que se ha representado un caso práctico de realización que se cita solamente a título de ejemplo no limitativo del alcance de la presente invención. DESCRIPCIÓN DE LOS DIBUJOS En los dibujos: La figura 1 ilustra una vista esquemática en alzado lateral de un dispositivo seca-manos según la invención seccionado según indica la línea de corte A-A de la figura 4. La figura 2 muestra una vista esquemática en alzado frontal del mismo sin el motor. La figura 3 es una vista esquemática en sección transversal del dispositivo según indica la línea de corte B-B de la figura 1. La figura 4 ilustra una vista esquemática en planta de dicho dispositivo sin el motor. La figura 5 muestra una vista esquemática en perspectiva del mismo sin el grupo motor-turbina. DESCRIPCIÓN DE UN EJEMPLO DE REALIZACIÓN De acuerdo con tales figuras, el dispositivo seca-manos ilustrado consta de un recinto o voluta (1) de entrada simple que presenta excéntricamente, en un lado, la zona o abertura (2) de admisión o entrada del aire ambiente y, alojándose en ella, un grupo motor-turbina (3) para la aspiración de dicho aire, quedando dispuesto el rodete centrífugo (4) , asimismo de entrada simple, dentro de la voluta (1) en tanto que el motor (5) sobresale de la misma (ver figura 3) . La indicada abertura o zona (2) está periféricamente doblada hacia adentro de la voluta (1) y presenta una anchura variable que, de mayor dimensión en su inicio y menos a la entrada del rodete (4) (figuras 3 y 5) , minimiza el bloqueo a la entrada del aire debido a la presencia del motor (5) . La voluta (1) presenta, desde su principio o inicio (6) , una configuración en espiral (7) cuya sección alrededor del rodete (4) (figura 1) aumenta progresivamente de tamaño y, en su finalización (71), se conecta con un conducto (8) por donde saldrá el aire aspirado, pudiendo estar constituido dicho conducto (tal como se ha ilustrado) por una prolongación de la voluta (1) . Este conducto (8) es recto, presenta una sección constante (que puede ser rectangular como se ha ilustrado o de otra forma) en toda su longitud, y conforma interiormente una cámara (81) de tranquilización que minimiza el bloqueo, en la misma, del aire saliente debido a una resistencia calefactora (9) y a unos nervios transversales y paralelos (10') que dicha cámara incorpora (figura 1), 'conformando los segundos una rejilla (10) que queda dispuesta entre la resistencia (9) y una zona de estrangulamiento progresivo (11) con que se remata el conducto (8) . Dicha zona de estrangulamiento, que no presenta cantos bruscos y que, en su finalización, define la boca (12) de salida del aire, permite la canalización progresiva del mismo y su concentración en el exterior, reduciéndose el nivel de turbulencia y minimizándose las pérdidas de presión, pudiendo ser la indicada boca rectangular (como se ha ilustrado) o de otra forma. Como puede comprenderse, la voluta (1) y el rodete (4) pueden ser de doble entrada y, en cualquier caso, el dispositivo irá montado en un adecuado cuerpo (no ilustrado) que sustentará sus partes y se fijará a la pertinente pared o paramento a través del mismo, comprendiendo para ello dicho cuerpo, en el ejemplo ilustrado, una base plana cuadrangular vertical (13) conformada por una cara lateral expandida del conjunto voluta-conducto (1, 8) (figuras 1 y 4) , siendo dicha cara la opuesta a la que presenta la zona (2) de admisión del aire ambiente, y presentando la base (13) los oportunos orificios (14) para la indicada fijación. La invención, dentro de su esencialidad, puede ser llevada a la práctica en otras formas de realización que difieran sólo en detalle de la indicada únicamente a título de ejemplo y a las cuales alcanzará igualmente la protección que se recaba . OBJECT OF THE INVENTION The present invention has as its object a hand dryer device of reduced dimensions. FIELD OF THE INVENTION This device is of the type comprising a turbine that, driven by a motor, aspirates ambient air by passing it through an enclosure or volute followed by an air duct that expels it at high speed through an outlet. The device has been designed primarily for application as a hand dryer of those installed in the toilets of many companies and in many public establishments, and which will be mounted, like those already existing, in a convenient body consisting of a base and a cover, the base being able to form a single piece with the volute or part thereof. BACKGROUND OF THE INVENTION Known devices of said type generally comprise a motor of a certain power to aspirate and expel the amount of air that is sufficient to fulfill its objective, said motor producing a certain consumption, being also of a certain size that impacts in the overall size of the device, having to resort, in general, to configurations complex that in order to reduce this size penalize its benefits. SUMMARY OF THE INVENTION With the device object of the present invention, maximum utilization is achieved in terms of fluid-dynamic performance, starting from reduced dimensions and consumption, by arranging the engine in the air inlet so that the suction itself favors its cooling and said device being characterized mainly by the configuration of the spiral volute on the intake side, allowing the entry of air despite the reduced dimensions and the location of the motor-turbine group in the intake zone of said air . Said spiral configuration represents a progressive increase in the size of the section of said volute from its beginning and surrounds the turbine constitutive impeller until it is connected with the air outlet duct, which is of constant section until it is finished off with a progressive throttling. which ends with the outlet of said air. This outlet is of smaller section than the conduit from which it proceeds, conforming the canalization by a smooth and progressive throttling, without abrupt or angular changes of the section through the air. Advantageously, the air outlet duct is constituted by a section that is an extension of the volute and whose interior forms, in the part of constant section, a chamber in which a heating resistor is mounted so that the air expelled by the device is hot, this chamber minimizing the blocking of the outgoing air due to the incorporation of said resistance and minimizing pressure losses. After the end of the section of constant section or 'chamber' there are arranged ribs that constitute the grid, interposed between the heating resistance and the throttling of the outlet duct, whose progressive decrease in section allows the progressive channeling of air and concentration of the same, increasing its speed and obtaining, in the outlet, a concentrated and fast air flow. These and other characteristics will be better derived from the detailed description that follows, which, for ease of understanding, is accompanied by a sheet of drawings in which a practical case of embodiment has been represented that is cited only by way of non-limiting example of the scope of the present invention. DESCRIPTION OF THE DRAWINGS In the drawings: Figure 1 illustrates a schematic side elevational view of a hand-dried device according to the invention sectioned according to the cut line AA of Figure 4. Figure 2 shows a schematic front elevation view thereof without the engine. Figure 3 is a schematic cross-sectional view of the device as indicated by the cutting line BB of Figure 1. Figure 4 illustrates a schematic plan view of said device without the motor. Figure 5 shows a schematic perspective view thereof without the motor-turbine group. DESCRIPTION OF AN EXAMPLE OF EMBODIMENT According to such figures, the hand-dried device illustrated consists of a simple entrance enclosure or volute (1) that eccentrically presents, on one side, the intake or entry zone or opening (2) of the ambient air and, housed therein, a motor-turbine group (3) for the aspiration of said air, the centrifugal impeller (4) being also arranged, also with a simple inlet, within the volute (1) while the motor ( 5) stands out from it (see figure 3). The indicated opening or zone (2) is peripherally bent inward of the volute (1) and has a variable width that, of greater dimension in its beginning and less at the entrance of the impeller (4) (figures 3 and 5), minimizes the air intake block due to the presence of the engine (5). The volute (1) has, from its beginning or beginning (6), a spiral configuration (7) whose section around the impeller (4) (figure 1) progressively increases in size and, at its completion (7 1 ), it is connected to a conduit (8) through which the sucked air will come out, said conduit being able to be constituted (as illustrated) by an extension of the volute (1). This conduit (8) is straight, has a constant section (which can be rectangular as illustrated or otherwise) along its entire length, and internally forms a soothing chamber (8 1 ) that minimizes blocking, in the same , of the outgoing air due to a heating resistance (9) and to transverse and parallel ribs (10 ') that said chamber incorporates (figure 1),' the latter forming a grid (10) that is arranged between the resistance (9) and a progressive throttling zone (11) with which the duct (8) is finished. Said throttling zone, which does not have sharp edges and, at its completion, defines the air outlet (12), allows its progressive channeling and its concentration outside, reducing the level of turbulence and minimizing losses pressure, which may be the indicated rectangular mouth (as illustrated) or otherwise. As can be understood, the volute (1) and the impeller (4) can be double input and, in any case, the device will be mounted on a suitable body (not illustrated) that will support its parts and will be fixed to the relevant wall or wall through it, understanding said body, in the illustrated example, a vertical quadrangular flat base (13) formed by an expanded lateral face of the volute-duct assembly (1, 8) (figures 1 and 4), said face being the opposite of the one in the area ( 2) of admission of the ambient air, and presenting the base (13) the appropriate holes (14) for the indicated fixation. The invention, within its essentiality, can be put into practice in other embodiments that differ only in detail from that indicated only by way of example and which will also achieve the protection sought.
