Description

Procedimiento de lavado para lavadora.Washing procedure for washing machine.

La presente invención se refiere a un procedimiento de lavado para una lavadora, particularmente, pero no exclusivamente, de tipo doméstico, en la que las prendas se introducen en un tambor montado de forma rotatoria alrededor su eje longitudinal horizontal y posicionado en un recipiente con su eje sustancialmente paralelo al del recipiente en el que se introducen una cantidad predeterminada de agua y agentes de lavado y en el que se realiza la operación de lavado impartiendo movimientos angulares al tambor que contiene la ropa en una dirección y la dirección opuesta alternativamente alrededor de su eje de rotación, intercalado con periodos de descanso, repetido varias veces hasta la finalización de un ciclo completo de lavado de una duración predeterminada.The present invention relates to a washing procedure for a washing machine, particularly, but not exclusively, of domestic type, in which the garments are they insert into a drum mounted rotatably around its axis longitudinal horizontal and positioned in a container with its axis substantially parallel to that of the container in which they are introduced a predetermined amount of water and washing agents and in which the washing operation is performed imparting angular movements to the drum that holds the clothes in one direction and the address alternately opposed around its axis of rotation, interspersed with rest periods, repeated several times until the completion of a complete wash cycle of a duration default

Los procedimientos de lavado del tipo indicado anteriormente son conocidos en la técnica y en su continuo desarrollo, se ha establecido una provisión para el uso de ciclos de rotación de tambores que tienen velocidades variables desde un mínimo para los ciclos iniciales a un máximo para los ciclos de rotación que terminan el lavado con el fin de aumentar la eficiencia del lavado, reducir los tiempos de lavado, evitar daños a la ropa y evitar el excesivo afieltramiento de la misma cuando se incluyen prendas de ropa hechas de lana.Washing procedures of the indicated type They are previously known in the art and in their continuum development, a provision for the use of cycles of rotation of drums that have variable speeds from a minimum for the initial cycles to a maximum for the cycles of rotation that finish the wash in order to increase the washing efficiency, reduce washing times, avoid damage to the clothes and avoid excessive felting of the same when They include clothes made of wool.

También se han propuesto procedimientos en los que el tambor, en lugar de finalizar rotaciones completas en una dirección y rotaciones en la dirección opuesta después de un periodo adecuado de descanso, está sujeto a oscilaciones angulares opuestas, el documento EP 2 41567 divulga dicho procedimiento de lavado.Procedures have also been proposed in the that the drum, instead of finishing complete rotations in a direction and rotations in the opposite direction after a period adequate rest, is subject to angular oscillations opposite, EP 2 41567 discloses said procedure of washed.

Los procedimientos de lavado conocidos y en particular, los del tipo mencionado anteriormente, aunque logran un resultado aceptable en términos de limpieza de las prendas de ropa que se lavan, no están sin embargo libres de desventajas y defectos. La eliminación o al menos, la reducción sustancial de estos es el principal objeto de la presente invención.The known washing procedures and in particular, those of the type mentioned above, although they achieve a acceptable result in terms of cleanliness of clothing that are washed, are not however free of disadvantages and defects. The elimination or at least the substantial reduction of These is the main object of the present invention.

En los procedimientos de lavado con ciclos de rotación de tambor que alternan en una dirección y la dirección opuesta con una creciente velocidad de rotación, uno de los problemas que se observan es que una capa de prendas se adhiere a las paredes del tambor y a pesar del cambio de dirección de la rotación del tambor, tiende a continuar comprendiendo las mismas prendas de ropa sin provocar esa mezcla de prendas que distribuiría la misma acción de lavado sobre todas las prendas. Incluso en los procedimientos de lavado que utilizan solo etapas de movimiento angular del tambor en una dirección y en la dirección opuesta, se observa una acción defectuosa de mezcla de las prendas de ropa en la que estas tienden a sufrir una acción de tipo pendular que les hace permanecer adheridas al mismo lado de la pared del tambor durante mucho tiempo y a pesar del hecho de que el ángulo de oscilación ha sido aumentado con respecto a la posición de descanso entre una ciclo de oscilación y otro.In washing procedures with cycles of drum rotation alternating in one direction and direction opposite with an increasing speed of rotation, one of the problems that are observed is that a layer of garments adheres to the walls of the drum and despite the change of direction of the drum rotation, tends to continue understanding the same clothes without causing that mix of clothes that would distribute the same washing action on all garments. Even in the washing procedures that use only movement stages angle of the drum in one direction and in the opposite direction, it observe a defective action of mixing the garments in which these tend to suffer a pendular action that Makes it stick to the same side of the drum wall for a long time and despite the fact that the angle of swing has been increased with respect to the resting position between one cycle of oscillation and another.

Esta falta de mezcla adecuada de las prendas de ropa supone tanto la limitación de la eficiencia de limpieza y la posibilidad de un mayor afieltramiento, particularmente en las prendas de lana.This lack of proper mixing of the garments of clothing involves both the limitation of cleaning efficiency and the possibility of greater felting, particularly in woolen garments

El problema que subyace a la presente invención es, por lo tanto, la concepción de un procedimiento de lavado para lavadoras para permitir un mejor lavado y un menor afieltrado de las prendas.The problem underlying the present invention It is, therefore, the conception of a washing procedure for washing machines to allow better washing and less felting of the garments

El problema se resuelve a través del procedimiento de lavado de acuerdo con la invención descrita en la reivindicación 1, dada a continuación.The problem is solved through washing procedure according to the invention described in the claim 1, given below.

La invención se describirá a continuación más particularmente con referencia a una realización proporcionada únicamente a modo de indicación y sin restricción, con la ayuda del diagrama de la figura 1 de los dibujos adjuntos, en los que se ilustran las etapas del procedimiento en forma de diagrama.The invention will be described below. particularly with reference to an embodiment provided only as an indication and without restriction, with the help of diagram of figure 1 of the attached drawings, in which They illustrate the steps of the procedure in diagram form.

Con referencia al diagrama de la figura 1, que ilustra el movimiento del tambor donde se introduce la ropa de una lavadora convencional en forma esquemática, el punto central T representa la línea del eje de rotación del tambor, no ilustrado, en el plano de la figura.With reference to the diagram in Figure 1, which illustrates the movement of the drum where the clothes of a conventional washing machine schematically, the central point T represents the axis of rotation of the drum, not illustrated, in the plane of the figure.

La circunferencia C del radio R representa la trayectoria de la periferia del tambor durante las operaciones de lavado.The circumference C of the radius R represents the trajectory of the periphery of the drum during the operations of washed.

El punto S representa la posición fija inferior de la periferia del tambor cuando se detiene la lavadora.The point S represents the lower fixed position from the periphery of the drum when the washer stops.

Los puntos 1, 2, 3 y 4 representan posiciones en las que comienzan movimientos angulares consecutivos del tambor en una sola dirección y terminan durante una primera etapa de movimiento del tambor, que tiene lugar por ejemplo en el sentido de las agujas del reloj, y en una segunda etapa de movimiento del tambor que tiene lugar, al contrario, en el sentido contrario a las agujas del reloj.Points 1, 2, 3 and 4 represent positions in which begin consecutive angular movements of the drum in one direction and end during a first stage of drum movement, which takes place for example in the sense of clockwise, and in a second stage of movement of the drum that takes place, on the contrary, in the opposite direction to clockwise

Las posiciones 1, 2, 3 y 4 están separadas de la posición fija S por los ángulos \alpha1, \alpha2, \alpha3, \alpha4 y \alpha5 que pueden ser iguales unos a otros durante la primera etapa del movimiento en el sentido de las agujas del reloj y la segunda etapa del movimiento en el sentido contrario de las agujas del reloj. Estos ángulos también pueden diferir unos de otros, al igual que también pueden ser diferentes o iguales las velocidades angulares a través de las cuales son transportados dichos ángulos por el tambor durante el movimiento angular.Positions 1, 2, 3 and 4 are separated from the fixed position S by angles α1, α2, α3, α4 and α5 that can be equal to each other during the first stage of movement clockwise and the second stage of the movement in the opposite direction of the clockwise These angles may also differ from others, just as they can also be different or the same angular speeds through which they are transported said angles by the drum during angular movement.

De acuerdo con una realización preferente, la suma total de los ángulos \alpha1, \alpha2,\alpha3, \alpha4 y \alpha5 que definen las posiciones S, 1, 2, 3 y 4 es de 360º \pm 10º.According to a preferred embodiment, the total sum of angles α1, α2, α3, α4 and α5 defining the positions S, 1, 2, 3 and 4 is 360º ± 10th.

En función de cada posición 1, 2, 3 y 4 de acuerdo con la invención, se proporciona un tiempo correspondiente t1, t2, t3 y t4, durante el cual se detiene el movimiento del tambor, siguiendo por lo tanto estos descansos después de los movimientos angulares en una dirección.Depending on each position 1, 2, 3 and 4 of according to the invention, a corresponding time is provided t1, t2, t3 and t4, during which the movement of the drum, therefore following these breaks after angular movements in one direction.

Los tiempos de parada mencionados anteriormente t1, t2, t3 y t4 pueden ser de duración equivalente, preferentemente entre 8,8 segundos y 1,2 segundos o pueden ser de diferente duración ya sea durante la primera etapa de movimiento en la dirección de las agujas del reloj o durante la segunda etapa de movimiento del tambor en la dirección contraria a las agujas del reloj.The stop times mentioned above t1, t2, t3 and t4 can be of equivalent duration, preferably between 8.8 seconds and 1.2 seconds or they can be of different duration either during the first stage of movement in the direction of clockwise or during the second stage of movement of the drum in the counterclockwise direction.

De nuevo de acuerdo con la invención, el procedimiento de lavado comprende una pausa prolongada para un tiempo predeterminado entre el final de la primera etapa de movimiento en la dirección de las agujas del reloj y el comienzo de la segunda etapa de movimiento del tambor en la dirección opuesta, esto es, en el ejemplo descrito, en la dirección contraria a las agujas del reloj.Again according to the invention, the washing procedure comprises a prolonged pause for a default time between the end of the first stage of clockwise movement and the beginning of the second stage of drum movement in the opposite direction, that is, in the example described, in the opposite direction to the clockwise

Esta pausa, que se produce en función de la posición S, puede tener una duración de entre 10 y 360 segundos.This pause, which occurs depending on the S position, can last between 10 and 360 seconds.

Repitiendo las etapas de lavado descritas anteriormente varias veces para cubrir la duración de un ciclo de lavado convencional, como se conoce, de media varía entre 25 minutos y 70 minutos, se obtuvo un excelente resultado en términos tanto de limpieza como de falta de afieltramiento de las prendas lavadas.Repeating the washing steps described previously several times to cover the duration of a cycle of conventional washing, as is known, on average varies between 25 minutes and 70 minutes, an excellent result was obtained in terms of both cleaning as lack of felting of the washed clothes.

Se debe entender que los tiempos de pausa indicados anteriormente, las velocidades angulares del movimiento de tambor y la amplitud de dichos movimientos angulares pueden variar de acuerdo con los requisitos sin ir, de este modo, más allá del alcance de la presente invención como se ha descrito y reivindicado en lo que sigue.It should be understood that the pause times indicated above, the angular velocities of the movement of drum and the amplitude of said angular movements can vary according to the requirements without going, thus, beyond of the scope of the present invention as described and claimed in the following.
