La presente invención se refiere a máquinas lavavajillas para uso doméstico y en particular a un dispositivo de filtro mejorado para ser utilizado en dichas máquinas.The present invention relates to machines dishwasher for domestic use and in particular to a device Improved filter to be used in such machines.
Es conocido que en los lavavajillas para uso doméstico hay un grupo de filtros en el fondo del depósito el cual proporciona la retención tanto de grandes residuos eliminados de los platos como las pequeñas partículas que puedan volverse a depositar en los platos reduciendo de ese modo la eficacia del lavado.It is known that in dishwashers for use domestic there is a group of filters at the bottom of the tank which provides retention of both large waste removed from dishes such as small particles that can be deposited again in the dishes thereby reducing the effectiveness of washing.
Con este propósito, el grupo de filtros generalmente incluye un filtro plano con una red de malla comparativamente grande (1 - 2 mm) colocada en el fondo del depósito y provista de una forma cóncava. Por lo tanto este filtro transporta una parte del agua hacia el área central inferior, en donde está dispuesto un conjunto de dos o tres filtros concéntricos verticales con puertos de paso progresivamente más pequeños.For this purpose, the filter group usually includes a flat filter with a mesh net comparatively large (1 - 2 mm) placed at the bottom of the tank and provided in a concave way. Therefore this filter transports a part of the water towards the lower central area, where it is arranged a set of two or three concentric vertical filters with progressively smaller passports.
Está claro que a fin de conseguir un buen rendimiento en el lavado el grupo de filtros debe ser capaz de retener las partículas de suciedad sin atascarse. Por esta razón es esencial fabricar filtros con un equilibrio correcto entre los requisitos del filtrado y de que no haya atascos. Los dispositivos de filtro de la técnica anterior tienen la desventaja de no conseguir este equilibrio de los requisitos, por lo que no permiten conseguir un rendimiento del lavado deseablemente alto.It is clear that in order to get a good washing performance the filter group must be able to retain dirt particles without getting stuck. For this reason it is essential to manufacture filters with a correct balance between filtering requirements and that there are no jams. The devices of prior art filter have the disadvantage of not achieve this balance of requirements, so they do not allow achieve desirably high wash performance.
Por lo tanto el objeto de la presente invención es proporcionar un dispositivo de filtro capaz de superar la desventaja anteriormente mencionada.Therefore the object of the present invention is to provide a filter device capable of overcoming the above mentioned disadvantage.
Este objeto se consigue por medio de un dispositivo que tiene las características descritas en la reivindicación 1.This object is achieved by means of a device that has the characteristics described in the claim 1.

La figura 5c es una vista en sección vertical a lo largo de la línea C-C de la figura 5a.Figure 5c is a vertical sectional view of along line C-C of figure 5a.
Con referencia a las figuras 1 y 2 se ve que en el fondo del depósito de un lavavajillas está dispuesto un filtro plano 1 con una red de malla grande (1-2 mm), que tiene una forma cóncava y centralmente provisto, en la zona más inferior, de un asiento para el dispositivo de filtro de acuerdo con la presente invención. Dicho dispositivo está substancialmente compuesto por un elemento de cubierta 2 fijado en la parte superior de un primer elemento de filtro 3 introducido dentro de un segundo elemento de filtro 4, éste último estando a su vez introducido dentro de un tercer elemento de filtro 5 con una red de malla cerrada (0,25-0,40 mm), un denominado micro-filtro.With reference to figures 1 and 2 it is seen that in the bottom of the tank of a dishwasher is arranged a filter flat 1 with a large mesh net (1-2 mm), which It has a concave shape and centrally provided, in the most bottom, of a seat for the filter device according to The present invention. Said device is substantially composed of a cover element 2 fixed at the top of a first filter element 3 introduced within a second filter element 4, the latter being in turn introduced within a third filter element 5 with a mesh network closed (0.25-0.40 mm), a so-called micro-filter
El trabajo del presente dispositivo de filtro no es diferente de aquél de los filtros conocidos por cuanto concierne al funcionamiento general. De hecho, el agua rociada sobre los platos lleva con ella residuos de comida cuando cae abajo sobre el fondo del depósito, los residuos mayores siendo retenidos en la superficie del grupo de filtro por el filtro plano 1. De este modo quedan claramente visibles para el usuario quien puede eliminarlos manualmente antes del siguiente ciclo de lavado. La mayor parte del agua (aproximadamente el 80%) pasa a través del filtro plano 1 y es directamente succionada por la bomba de lavado, mientras que la parte restante entra en el dispositivo de filtro central a través de una pluralidad de puestos de paso P, como se explicará mejor más adelante. Puesto que durante el ciclo de lavado el agua contenida en el lavavajillas se recicla mediante la bomba de lavado aproximadamente de 10 a 12 veces por minuto, se puede suponer con una buena aproximación que durante el ciclo completo todas las partículas en el agua pasarán finalmente a través del dispositivo de filtro.The work of the present filter device does not It is different from that of the known filters as far as it is concerned to general operation. In fact, water sprayed on dishes carry with it food waste when it falls down on the deposit fund, the major waste being retained in the surface of the filter group by the flat filter 1. In this way they are clearly visible to the user who can remove them manually before the next wash cycle. Most of the water (approximately 80%) passes through the flat filter 1 and is directly sucked by the wash pump, while the remaining part enters the central filter device through a plurality of P-way posts, as will be better explained more ahead. Since during the wash cycle the water contained in the dishwasher is recycled using the wash pump approximately 10 to 12 times per minute, it can be assumed with a good approximation that during the complete cycle all particles in the water will eventually pass through the device filter.
Las partículas retenidas por los diversos elementos del dispositivo de filtro caerán entonces por gravedad dentro de un espacio de drenaje subyacente VS, desde el cual son succionadas por una bomba de drenaje PS. Además, a fin de mantener limpio el tercer elemento de filtro exterior 5, o micro-filtro, está provisto un conducto de lavado CL que tiene una pluralidad de boquillas las cuales rocían tangencialmente el micro-filtro 5. El agua que proviene de la bomba de lavado es alimentada periódicamente dentro del conducto CL, por ejemplo al principio de cada paso de aclarado, abriendo una electroválvula EV. De este modo la superficie completa del micro-filtro 5, el cual está giratoriamente montado en su asiento, es lavada por una contracorriente que proviene de las boquillas del conducto CL.The particles retained by the various elements of the filter device will then fall by gravity within an underlying drainage space VS, from which they are sucked by a PS drain pump. In addition, in order to maintain clean the third outer filter element 5, or micro-filter, a CL washing line is provided which has a plurality of nozzles which spray tangentially the micro-filter 5. The water that comes from the wash pump is fed periodically inside of the CL duct, for example at the beginning of each rinse step, opening an EV solenoid valve. Thus the entire surface of micro-filter 5, which is rotatably mounted on its seat, it is washed by a counter current that comes from the nozzles of the CL duct.
Con referencia también a las figuras 3a-3c, las características de los elementos del presente dispositivo de filtro se ilustran ahora en detalle.With reference also to the figures 3a-3c, the characteristics of the elements of the Present filter device are now illustrated in detail.
El elemento de cubierta 2 (figuras 3a-3c) tiene una forma circular substancialmente de cono truncado con una superficie lateral cóncava 6 que tiene un radio de curvatura ``R'' (figura 1) entre 15 y 25 mm, preferiblemente 20 mm. En dicha superficie cóncava 6 están formadas una pluralidad de ranuras radiales 7, en particular doce ranuras en la realización ilustrada, simétricamente dispuestas y que tienen una anchura entre 1,2 y 1,6 mm, preferiblemente 1,4 mm. En la parte superior de la cubierta 2 está formado un agujero axial circular 8 que tiene un diámetro ``d'' (figura 1) entre 5 y 7 mm, preferiblemente 7 mm. La superficie cóncava 6 está dividida en cuatro partes iguales por cuatro aletas ortogonales verticales 9 que se extienden desde el borde del agujero axial 8 hasta la periferia 10 de la cubierta 2.The cover element 2 (figures 3a-3c) has a substantially circular shape of truncated cone with a concave side surface 6 that has a radius of curvature `` R '' (figure 1) between 15 and 25 mm, preferably 20 mm. On said concave surface 6 are formed a plurality of radial grooves 7, in particular twelve grooves in the illustrated embodiment, symmetrically arranged and having a width between 1.2 and 1.6 mm, preferably 1.4 mm. In the part top of the cover 2 a circular axial hole 8 is formed which has a diameter `` d '' (figure 1) between 5 and 7 mm, preferably 7 mm. The concave surface 6 is divided into four equal parts by four vertical orthogonal fins 9 that they extend from the edge of the axial hole 8 to the periphery 10 of cover 2.
La fijación del elemento de cubierta 2 en el primer elemento de filtro 3 se lleva a cabo a través de un par de dientes opuestos 11 integralmente formados, junto con un par de pasadores de referencia 12, en la cara inferior de la cubierta 2. Los dientes 11 y los pasadores 12 se acoplan en los correspondientes agujeros 13 formados en el primer elemento de filtro 3 (figura 1 y figura 4a), de forma que mantienen la cubierta 2 centrada y separada con respecto al primer filtro 3. El diámetro de la cubierta 2 es menor que aquél de la periferia interior de la parte superior 14 del primer filtro 3, de forma que entre dicha periferia 14 y el borde 10 de la cubierta 2 hay un espacio en forma de anillo circular que tiene una anchura ``L'' (figura 1) entre 4,5 y 6,5 mm, preferiblemente 5,4 mm.Fixing the cover element 2 in the first filter element 3 is carried out through a pair of opposite teeth 11 integrally formed, together with a pair of reference pins 12, on the underside of the cover 2. The teeth 11 and the pins 12 are coupled in the corresponding holes 13 formed in the first filter element 3 (figure 1 and figure 4a), so that the cover 2 is centered and separated with respect to the first filter 3. The diameter of the cover 2 is less than that of the inner periphery of the upper part 14 of the first filter 3, such that between said periphery 14 and edge 10 from deck 2 there is a circular ring-shaped space that It has a width `` L '' (figure 1) between 4.5 and 6.5 mm, preferably 5.4 mm.
Dicho espacio en forma de anillo circular, las ranuras 7 y el agujero axial 8 de la cubierta 2 juntos son los puertos de paso P anteriormente mencionados los cuales permiten que el agua entre en el dispositivo de filtro de acuerdo con la presente invención.Said circular ring-shaped space, the slots 7 and the axial hole 8 of the cover 2 together are the P-pass ports mentioned above which allow water enters the filter device according to the present invention.
El primer elemento de filtro 3 (figuras 4a-4c) tiene un cuerpo cilíndrico circular 15 que termina en la parte superior con un disco 16 en el cual están formados los agujeros 13 anteriormente mencionados. En el cuerpo cilíndrico 15 están formadas una pluralidad de ranuras verticales 17, en particular seis ranuras en la realización ilustrada, dispuestas simétricamente y que tienen una anchura entre 2,5 y 3,5 mm, preferiblemente 3 mm. Estas ranuras 17 se extienden desde el disco 16 hasta casi el extremo inferior del cuerpo cilíndrico 15. Además, debajo del disco 16 están formadas dos orejas verticales opuestas 18 con una forma tal que se acoplan en los correspondientes asientos 19 formados en el segundo elemento de filtro 4 (figura 5a). De este modo, el primer filtro 3 está impedido contra el giro axial con respecto al segundo filtro 4 en el cual está introducido.The first filter element 3 (figures 4a-4c) has a circular cylindrical body 15 that ends at the top with a disk 16 on which they are formed the holes 13 mentioned above. In the body cylindrical 15 are formed a plurality of vertical grooves 17, in particular six slots in the illustrated embodiment, symmetrically arranged and having a width between 2.5 and 3.5 mm, preferably 3 mm. These slots 17 extend from the disk 16 to almost the lower end of the cylindrical body 15. In addition, two vertical ears are formed under disc 16 opposite 18 in such a way that they fit into the corresponding seats 19 formed in the second filter element 4 (figure 5a). In this way, the first filter 3 is prevented against axial rotation with respect to the second filter 4 in which it is inserted.
El segundo elemento de filtro 4 (figuras 5a-5c) también tiene un cuerpo cilíndrico circular 20 cuyo diámetro se reduce aproximadamente a media altura. En el cuerpo cilíndrico 20 están formadas una pluralidad de ranuras verticales 21, en particular cuarenta y ocho ranuras en la realización ilustrada, dispuestas simétricamente y que tienen una anchura entre 0,8 y 1,2 mm, preferiblemente 1,2 mm. Estas ranuras 21 se extienden desde el extremo inferior del cuerpo cilíndrico 20 hasta casi la parte superior, con una discontinuidad en el cambio de diámetro. La integridad estructural del cuerpo 20 está asegurada por una base inferior en la cual está formado un asiento central 22, para introducir el primer filtro 3, así como una pluralidad de agujeros 23, dieciséis en la realización ilustrada, dispuestos simétricamente para el drenaje de las partículas filtradas.The second filter element 4 (figures 5a-5c) also has a circular cylindrical body 20 whose diameter is reduced to approximately half height. In the cylindrical body 20 are formed a plurality of grooves vertical 21, in particular forty-eight slots in the illustrated embodiment, symmetrically arranged and having a width between 0.8 and 1.2 mm, preferably 1.2 mm. These slots 21 they extend from the lower end of the cylindrical body 20 to almost the top, with a discontinuity in the change of diameter. The structural integrity of the body 20 is ensured by a lower base on which a central seat 22 is formed, to introduce the first filter 3, as well as a plurality of holes 23, sixteen in the illustrated embodiment, arranged symmetrically for the drainage of the filtered particles.
El segundo filtro 4 se introduce a su vez dentro del micro-filtro 5 (figuras 1, 2) el cual simplemente consiste en una red cilíndrica, con una malla de 0,25 mm, provista con bordes de refuerzo superior e inferior. El conjunto global de los diversos elementos del presente dispositivo de filtro se consigue acoplando el borde superior del micro-filtro 5 con la periferia exterior del disco 16 del primer filtro 3, el cual se prolonga con respecto al segundo filtro 4.The second filter 4 is in turn inserted into of micro-filter 5 (figures 1, 2) which it simply consists of a cylindrical net, with a mesh of 0.25 mm, provided with upper and lower reinforcement edges. Set global of the various elements of the present filter device is achieved by attaching the upper edge of the micro-filter 5 with the outer periphery of the disc 16 of the first filter 3, which extends with respect to the second filter 4.
Está claro que la realización anteriormente descrita e ilustrada del dispositivo de acuerdo con la invención es sólo un ejemplo susceptible de diversas modificaciones. En particular, el número y la disposición de las ranuras 7, 17, 21 se pueden variar algo y lo mismo es cierto para los agujeros 13 y 23. De igual modo, la forma, el tamaño y los mecanismos de acoplamiento de los elementos que componen el dispositivo se pueden cambiar de acuerdo con requisitos específicos, siempre que se mantengan las relaciones entre los diversos puertos de paso anteriormente descritos. Por ejemplo, el acoplamiento rápido de los dientes 11 dentro de los agujeros 13 se puede sustituir por un acoplamiento de bayoneta equivalente llevado a cabo por dientes y agujeros con las formas adecuadas.It is clear that the realization above described and illustrated of the device according to the invention is Only one example susceptible to various modifications. In In particular, the number and arrangement of slots 7, 17, 21 are Some may vary and the same is true for holes 13 and 23. Similarly, the shape, size and coupling mechanisms of the elements that make up the device can be changed from according to specific requirements, provided that the relationships between the various ports of passage above described. For example, quick coupling of teeth 11 inside holes 13 it can be replaced by a coupling of equivalent bayonet carried out by teeth and holes with the suitable forms.
