Description

Tambor de lavadora.Washing machine drum

Objeto de la invenciónObject of the invention

La invención se refiere a un tambor de lavadora que está constituido por una pared cilíndrica que incluye una pluralidad de orificios, y que está unida a dos bases mediante un agrafado.The invention relates to a washing machine drum which is constituted by a cylindrical wall that includes a plurality of holes, and that is joined to two bases by a attached

Antecedentes de la invenciónBackground of the invention

Es conocido que los tambores de las lavadoras están constituidos por una pared lateral dotada de una pluralidad de orificios, y que está unida por sus extremos a una base posterior y a otra anterior mediante un agrafado que define un saliente perimetral constituido por un primer doblez de 180º de un tramo de la pared de la base sobre la pared cilíndrica, y por un segundo doblez de 180º de la doble pared formada, tras el primer doblez, por la base y la pared cilíndrica, sobre dicha pared lateral cilíndrica.It is known that washing machine drums they are constituted by a side wall endowed with a plurality of holes, and that is joined by its ends to a base later and to another previous one by means of a graffiti that defines a perimeter projection constituted by a first 180º fold of a section of the base wall on the cylindrical wall, and by a second 180º fold of the double wall formed, after the first fold, by the base and the cylindrical wall, on said side wall  cylindrical

Descripción de la invenciónDescription of the invention

La velocidad de centrifugado de las lavadoras, cada vez es más alta, lo que provoca que el tambor deba soportar unos esfuerzos mayores que pueden llegar a producir un desgarro en la unión agrafada, de la superficie lateral cilíndrica con las bases.The spin speed of the washing machines, it is getting louder, which causes the drum to withstand greater efforts that can produce a tear in the aggravated junction of the cylindrical lateral surface with the bases.

Además, a altas velocidades de centrifugado, se produce un combado de la pared lateral cilíndrica, lo que a su vez provoca que el esfuerzo a soportar por los agrafados sea mayor, lo que facilita que se produzca el desgarro del tambor en las zonas agrafadas.In addition, at high spin speeds, it it produces a cylindrical side wall bend, which in turn causes that the effort to support by the agrafados is greater, what which facilitates the tearing of the drum in the areas pleased.

La invención tiene por objeto proporcionar un refuerzo al agrafado que constituye la unión entre las bases y la pared lateral cilíndrica, para que estas uniones soporten mayores esfuerzos, como los que se producen cuando se centrifuga a altas revoluciones.The object of the invention is to provide a reinforcement to the agrafado that constitutes the union between the bases and the cylindrical side wall, so that these joints support larger efforts, such as those that occur when centrifuged at high Revolutions

Además la invención tiene por objeto reforzar la pared lateral cilíndrica, igualmente para dotar a ésta de una mayor resistencia y de mecanismos que preserven la unión agrafada, para permitir soportar mayores esfuerzos, como los producidos cuando se centrifuga a altas revoluciones.In addition, the invention aims to strengthen the cylindrical side wall, also to provide it with a greater resistance and mechanisms that preserve the aggravated union, to allow to bear greater efforts, such as those produced when centrifuge at high revolutions.

Para resolver los inconvenientes anteriormente indicados, la invención ha desarrollado un tambor de lavadora, que al igual que los convencionales está constituido por una pared cilíndrica dotada de una pluralidad de orificios, y que está unida por sus extremos a una base anterior y otra posterior mediante un agrafado perimetral; y se caracteriza porque sobre el agrafado se realiza un quiebro que afecta a todas las paredes que constituyen dicho agrafado, de manera que esta estructura determina una mayor resistencia del agrafado frente a los esfuerzos que se producen, por la acción de la fuerza centrífuga sobre la pared cilíndrica, de modo que se reduce la posibilidad de desgarro y/o de desdoblado del agrafado cuando el tambor gira a altas velocidades.To solve the problems above indicated, the invention has developed a washing machine drum, which like conventional ones it is constituted by a wall cylindrical endowed with a plurality of holes, and which is joined by its ends to an anterior and a posterior base by means of a perimeter fencing; and it is characterized because on the agrafado one make a bankruptcy that affects all the walls that constitute said attached, so that this structure determines a greater resistance of the engrafado against the efforts that occur, by the action of the centrifugal force on the cylindrical wall, of so that the possibility of tearing and / or unfolding is reduced of the engrafado when the drum rotates at high speeds.

El quiebro está dispuesto longitudinalmente sobre cada una de las paredes que lo constituyen.The bankruptcy is arranged longitudinally over each of the walls that constitute it.

En una realización de la invención el quiebro está dispuesto oblicuo al agrafado, es decir los diferentes quiebros practicados en cada una de las diferentes paredes que constituyen el agrafado, quedan alineados en sentido oblicuo.In one embodiment of the invention the bankruptcy it is arranged oblique to the agrafado, that is to say the different bankruptcies practiced in each of the different walls that they constitute the agrafado, they are aligned obliquely.

Además el tambor de la invención presenta como característica adicional el hecho de que la pared cilíndrica está dotada de una pluralidad de pequeñas depresiones, de manera que se aumenta la superficie de dicha pared cilíndrica, de forma que proporciona una mayor resistencia que dificulta que la pared cilíndrica se abombe al girar a altas velocidades, y en caso de que se produzca dicho abombado, éste afecta a las depresiones y no al agrafado, lo que además se traduce en que las uniones agrafadas tengan que soportar un menor esfuerzo y por consiguiente se hace más difícil el desgarro en la zona del agrafado.In addition the drum of the invention presents as additional feature the fact that the cylindrical wall is endowed with a plurality of small depressions, so that increases the surface of said cylindrical wall, so that provides greater resistance that hinders the wall cylindrical bulges when turning at high speeds, and in case this bulging occurs, it affects the depressions and not the engrafado, which also translates into the aggravated unions have to endure less effort and therefore it is done more difficult tearing in the area of the engrafado.

En una realización de la invención cada depresión incluye uno de los orificios del tambor, pero obviamente estos orificios podrían estar fuera de las depresiones o alternar en las mismas según cualquier configuración que se deseé.In one embodiment of the invention each depression includes one of the holes in the drum, but obviously these holes could be out of the depressions or alternate in the same according to any desired configuration.

También cabe señalar que las depresiones, según una forma de realización de la invención, presentan una sección tronco-cónica, pero igualmente éstas podrían presentar cualquier sección.It should also be noted that depressions, according to An embodiment of the invention has a section conical trunk, but these could also submit any section

A continuación para facilitar una mejor comprensión de esta memoria descriptiva y formando parte integrante de la misma, se acompañan una serie de figuras en las que con carácter ilustrativo y no limitativo se ha representado el objeto de la invención.Next to facilitate a better understanding of this descriptive report and being an integral part of the same, they accompany a series of figures in which with illustrative and non-limiting nature has been represented the object of the invention.

Descripción de la forma de realización preferidaDescription of the preferred embodiment

A continuación se realiza una descripción de la invención basada en las figuras anteriormente comentadas.Below is a description of the invention based on the figures discussed above.

El tambor de la invención, al igual que los convencionales está constituido por una pared cilíndrica 3 que se une mediante un agrafado 5 a una base posterior 1 y a una base anterior 2.The drum of the invention, as well as the conventional is constituted by a cylindrical wall 3 that joins by means of an appendix 5 to a rear base 1 and a base previous 2.

Además la superficie de la pared cilíndrica 3 está dotada de una pluralidad de orificios 4 de entrada y salida de agua.In addition the surface of the cylindrical wall 3 it is provided with a plurality of inlet and outlet holes 4 of Water.

En la figura 2 se muestra una sección parcial de los elementos descritos con anterioridad según se prevé en el estado de la técnica, en el que se aprecia que el agrafado 5 está determinado por un primer doblez de 180º de un tramo de la pared de la base 1 ó 2, sobre la pared cilíndrica 3, de manera que a continuación se efectúa un segundo doblez, igualmente de 180º, de la doble pared que se formó tras el primer doblez, sobre la pared cilíndrica 3.Figure 2 shows a partial section of the elements described above as provided in the state of the art, in which it is appreciated that the appendix 5 is determined by a first 180º fold of a section of the wall of  the base 1 or 2, on the cylindrical wall 3, so that at then a second fold, also of 180º, of the double wall that formed after the first fold, on the wall cylindrical 3.

Esta configuración, tal y como ya fue expresado en apartados anteriores, presenta el inconveniente de que cuando el tambor debe girar a altas velocidades, se puede provocar el desgarro del tambor de lavado en la unión agrafada 5, al tiempo que se puede producir un combado de la pared cilíndrica 3, lo que repercute en que los extremos agrafados 5 deban de soportar un mayor esfuerzo, lo que a su vez facilita que se provoque el desgarro del tambor.This configuration, as already expressed in previous sections, it has the disadvantage that when the drum must rotate at high speeds, it can cause the tear of the wash drum in the aggravated junction 5, while  a crank of the cylindrical wall 3 can be produced, which it has the effect that the attached ends 5 must withstand a greater effort, which in turn facilitates the provocation of tear of the drum.

Para resolver estos inconvenientes, la invención incorpora la característica novedosa de que sobre el agrafado 5 se realiza un quiebro, por ejemplo, presionando con dos rulinas a lo largo de todo el agrafado, de manera que dicho quiebro afecta a todas las paredes que lo constituyen.To solve these inconveniences, the invention incorporates the novel feature that on the agrafado 5 is Make a bankruptcy, for example, by pressing with two wheels throughout the entire collection, so that this bankruptcy affects all the walls that constitute it.

Este quiebro incrementa la tensión que puede soportar el tambor cuando gira a grandes velocidades de centrifugado, de manera que se reduce considerablemente la probabilidad de que pueda llegar a producirse el desgarro del tambor.This break increases the tension that can support the drum when it rotates at high speeds of centrifuged, so that the probability that the tearing of the drum.

Además, para evitar el abombamiento de la pared cilíndrica 3, en ésta se practican unas depresiones 7 de sección tronco-cónica en cuyo fondo se incluyen los orificios 4 de entrada/salida del agua al tambor para realizar el lavado.Also, to avoid bulging the wall cylindrical 3, in this section depressions 7 of section are practiced conical trunk whose bottom includes the water inlet / outlet holes 4 to the drum to perform the washed.

Esta configuración de las depresiones proporciona una mayor superficie y resistencia del tambor, lo que determina que si la superficie cilíndrica 3 se comba, ello afecta a las depresiones 7, de manera que se impide que sufran los extremos agrafados 5, aumentándose considerablemente la probabilidad de que no se produzca el desgarro por estas zonas.This configuration of depressions provides greater drum surface and resistance, which determines that if the cylindrical surface 3 sags, it affects the depressions 7, so that extremes are prevented from suffering 5, significantly increasing the probability that tear does not occur in these areas.

Por tanto, mediante el tambor de la invención se consigue una mayor resistencia al esfuerzo en la pared lateral y en la zona de los agrafados, y al mismo tiempo éstos se preservan en caso de que se produzca el combado de la superficie lateral 5.Therefore, by means of the drum of the invention, achieves greater resistance to stress on the side wall and in the zone of the engrafados, and at the same time these are preserved in in case of side surface bending 5.
