15 recirculacion del liquido de lavado y / o aclarado con el fin de lavar y aclarar , respectivamente, la colada y, finalmente, al menos una fase de descarga del liquido de lavado y / o aclarado utilizado. 15 recirculation of the washing and / or rinsing liquid in order to wash and rinse, respectively, the laundry and, finally, at least one phase of discharge of the washing and / or rinsing liquid used.
Las lavadoras para la colada que funcionan de acuerdo con el procedimiento de lavado y / o aclarado descrito con anterioridad son conocidas en el ambito de este campo. Washing machines that operate according to the washing and / or rinsing procedure described above are known in the field of this field.
Un ejemplo se ilustra y describe en el documento US-A-5,345,637. An example is illustrated and described in US-A-5,345,637.
20 Como es evidente a partir de dicho documento de la tecnica conocida, el liquido para humedecer la colada situada dentro del tambor para ser lavada es inicialmente cargado por medio de la introduccion en el tanque de una cantidad especifica de liquido, dependiendo sustancialmente del peso de la colada que va a ser lavada, extraido de una fuente apropiada de agua caliente o fria. As is evident from said known technique document, the liquid to moisten the laundry inside the drum to be washed is initially charged by means of introducing a specific amount of liquid into the tank, substantially depending on the weight of the laundry to be washed, extracted from an appropriate source of hot or cold water.
El liquido pasa por la colada y se acumula en el fondo del tanque hasta alcanzar un nivel determinado a traves del 25 cual pasa el tambor con la colada, lo que determina que el liquido impregne la colada durante la rotacion de aquel. The liquid passes through the laundry and accumulates at the bottom of the tank until it reaches a certain level through which the drum passes through the laundry, which determines that the liquid permeates the laundry during its rotation.
Resulta obvio que, de acuerdo con dicha tecnica conocida, se requiere una cantidad considerable de liquido para humedecer la colada, lo que, por si mismo, constituye un coste y lo que, asi mismo, se traduce en una resistencia considerable al movimiento del tambor que contiene la colada cuando dicho tambor pasa a traves del liquido dispuesto en la trayectoria inferior de su rotacion dentro del tanque. It is obvious that, according to said known technique, a considerable amount of liquid is required to moisten the laundry, which, in itself, constitutes a cost and which, likewise, translates into considerable resistance to drum movement which contains the laundry when said drum passes through the liquid arranged in the lower trajectory of its rotation inside the tank.
30 Esta circunstancia refleja la necesidad de incluir un motor electrico en la maquina provisto de un par de torsion apropiado y, por consiguiente, de una potencia apropiada, con la correspondiente absorcion de energia, con el fin de hacer rotar el tambor incluso durante la fase inicial de humedecimiento de la colada. 30 This circumstance reflects the need to include an electric motor in the machine provided with an appropriate torque and, consequently, of an appropriate power, with the corresponding energy absorption, in order to rotate the drum even during the phase Initial wetting of the laundry.
Ya se ha propuesto en la tecnica limitar la cantidad del liquido de lavado y / o aclarado de tal forma que, durante las fases operativas de lavado y / o aclarado en las cuales el tambor esta rotando y la bomba de recirculacion retira el It has already been proposed in the art to limit the amount of the washing and / or rinsing liquid in such a way that, during the operational washing and / or rinsing phases in which the drum is rotating and the recirculation pump removes the
35 liquido del tanque y lo devuelve a el, el nivel dinamico del liquido no exceda el plano tangencial con el tanque en el punto mas bajo de su perfil para eliminar o reducir la resistencia que el liquido plantea contra el movimiento del tambor cuando pasa a traves del liquido. 35 liquid from the tank and returns it to it, the dynamic level of the liquid does not exceed the tangential plane with the tank at the lowest point of its profile to eliminate or reduce the resistance that the liquid poses against the movement of the drum when it passes through of the liquid
Ejemplos de otra tecnica conocida de este tipo dirigida a reducir la energia utilizada por la lavadora para la colada, se describen en el documento EP-A-0,726,349 y, asi mismo, en el documento EP-A-0,597,509. Examples of another known technique of this type aimed at reducing the energy used by the washing machine for laundry are described in EP-A-0,726,349 and, likewise, in EP-A-0,597,509.
40 Sin embargo, de acuerdo con esta ultimisima tecnica conocida, se destaca que la cantidad de liquido, cuando es liberada dentro del sistema hidraulico de la maquina, y en particular dentro del tanque de dicha maquina con el fin de humedecer la colada, alcanza una altura piezometrica en condiciones estaticas que necesariamente sobrepasa el plano tangencial con el borde del tambor dado que, solo en condiciones dinamicas debidas a la recirculacion durante las fases operativas de lavado y / o aclarado, el nivel del liquido se hace descender hasta el nivel del plano 40 However, according to this latest known technique, it is emphasized that the amount of liquid, when released within the hydraulic system of the machine, and in particular inside the tank of said machine in order to moisten the laundry, reaches a piezometric height in static conditions that necessarily exceeds the tangential plane with the edge of the drum since, only in dynamic conditions due to recirculation during the operational phases of washing and / or rinsing, the liquid level is lowered to the level of the plane
45 tangencial mencionado con anterioridad con respecto al borde del tambor. 45 mentioned above with respect to the edge of the drum.
Esto significa que, durante la fase de humidificacion de la colada, cuando el tambor rota con el fin de distribuir el liquido de la colada, el tambor que contiene la colada se mueve pero esta todavia paralizado con el liquido lo que plantea una resistencia contra el movimiento de dicho tambor. This means that, during the humidification phase of the laundry, when the drum rotates in order to distribute the laundry liquid, the drum containing the laundry moves but is still paralyzed with the liquid which poses a resistance against the movement of said drum.
Por consiguiente, de acuerdo con la tecnica conocida mencionada con anterioridad, sigue siendo necesario utilizar Therefore, according to the known technique mentioned above, it is still necessary to use
50 un motor electrico, cuya potencia sea la apropiada y mayor de la que seria estrictamente necesaria durante las fases operativas de lavado y aclarado durante las cuales, gracias a la recirculacion, el nivel dinamico del liquido decrece hasta por debajo del plano tangencial con respecto al borde del tambor, no obstruyendo ya su movimiento. 50 an electric motor, whose power is appropriate and greater than would be strictly necessary during the operational phases of washing and rinsing during which, thanks to the recirculation, the dynamic level of the liquid decreases to below the tangential plane with respect to the drum edge, no longer obstructing its movement.
El objetivo de la presente invencion es poder reducir en mayor medida la absorcion de energia por la lavadora para la colada, reduciendo con ello el par de torsion y la potencia necesaria para que el motor electrico rote el tambor asi como la necesaria para calentar el liquido de lavado. The objective of the present invention is to be able to reduce the absorption of energy by the washing machine for the laundry to a greater extent, thereby reducing the torque and the power necessary for the electric motor to rotate the drum as well as that necessary to heat the liquid. washing
Este y otros objetivos, los cuales se pondran de manifiesto con mayor claridad a partir de la descripcion subsecuente, se consiguen con el procedimiento segun la invencion de acuerdo con la reivindicacion 1. This and other objectives, which will become clearer from the subsequent description, are achieved by the method according to the invention according to claim 1.
A continuacion se describira la invencion con mayor detalle con referencia al dibujo ilustrado de la Fig. 1, en la cual se muestra una seccion transversal de un tanque para una lavadora para la colada con un tambor asociado. In the following, the invention will be described in greater detail with reference to the illustrated drawing of Fig. 1, in which a cross section of a tank for a laundry washing machine with an associated drum is shown.
Con referencia al dibujo esquematico mencionado anteriormente, el tanque de una lavadora para la colada esta indicado mediante la referencia numeral 1. el tanque 1 esta provisto de una porcion inferior 1a que tiene forma circular. With reference to the schematic drawing mentioned above, the tank of a washing machine for laundry is indicated by reference numeral 1. Tank 1 is provided with a lower portion 1a which has a circular shape.
Dentro del tanque 1 esta dispuesto un tambor 2, el cual, de una manera convencional, esta dispuesto para que pueda rotar mediante un apropiado motor electrico y con respecto a una transmision mecanica, no mostrada, alrededor de un eje geometrico sustancialmente horizontal X - X. Inside the tank 1 a drum 2 is arranged, which, in a conventional manner, is arranged so that it can rotate by an appropriate electric motor and with respect to a mechanical transmission, not shown, around a substantially horizontal geometric axis X-X .
Un deposito 3 dispuesto por debajo de la porcion inferior del tanque 1 y esta conectado a la parte mas baja de la porcion inferior del tanque, donde una abertura 4 esta dispuesta, a traves de un conducto 5 y hacia una pluralidad de toberas a traves del circuito de recirculacion ilustrado mediante la linea 7. Aunque el deposito 3 se muestra en el dibujo dispuesto verticalmente por debajo del tanque 1, debe entenderse en la descripcion y en las reivindicaciones relevantes que puede estar situado por debajo del tanque pero en un lado de la linea vertical que pasa a traves de la abertura 4 de la porcion inferior del tanque. Las toberas 6 estan dispuestas en la parte superior del tanque 1 y permiten que el liquido de lavado y / o aclarado sea liberado a traves de la pared periferica perforado del tambor 2. A reservoir 3 disposed below the lower portion of the tank 1 and is connected to the lowest part of the lower portion of the tank, where an opening 4 is arranged, through a conduit 5 and towards a plurality of nozzles through the recirculation circuit illustrated by line 7. Although the tank 3 is shown in the drawing arranged vertically below the tank 1, it should be understood in the description and in the relevant claims that it may be located below the tank but on one side of the tank. vertical line that passes through the opening 4 of the lower portion of the tank. The nozzles 6 are arranged in the upper part of the tank 1 and allow the washing and / or rinsing liquid to be released through the perforated peripheral wall of the drum 2.
Otra tobera 8, alimentada a traves del conducto ilustrado por la linea 9, esta a su vez conectada al conducto 7, y puede estar dispuesta para liberar el liquido de lavado y / o aclarado en la puerta de acceso al tambor 2. Another nozzle 8, fed through the conduit illustrated by the line 9, is in turn connected to the conduit 7, and may be arranged to release the washing liquid and / or rinse in the access door to the drum 2.
Los conductos 7 y 9 que alimentan la tobera 6 y 8 estan conectados a una bomba de recirculacion 10 dispuesta sobre el deposito 3, sobre el cual una bomba de descarga 11 esta tambien montada. The ducts 7 and 9 that feed the nozzle 6 and 8 are connected to a recirculation pump 10 arranged on the tank 3, on which a discharge pump 11 is also mounted.
Dicha bomba de descarga 11 esta conectada a traves de un conducto 12 a una salida 13 situada fuera de la lavadora para la colada. Said discharge pump 11 is connected through a conduit 12 to an outlet 13 located outside the washing machine for laundry.
Una fuente de agua externa, identificada con la referencia numeral 14 carga el sistema hidraulico con la cantidad necesaria y predeterminada de liquido para el funcionamiento de la maquina a traves de una valvula 15 y de un conducto 16. An external water source, identified with reference numeral 14, loads the hydraulic system with the necessary and predetermined amount of liquid for the operation of the machine through a valve 15 and a conduit 16.
Un cajetin 17 para el detergente puede estar insertado dentro de la trayectoria del conducto 16 si el programa de la maquina provee este elemento. A box 17 for the detergent may be inserted into the path of the conduit 16 if the machine program provides this element.
Un manometro 18 esta dispuesto sobre el deposito 3 para medir y de esta forma regular la altura de la columna de liquido que es introducida en el sistema hidraulico de la maquina cuando la valvula 15 se abre. A pressure gauge 18 is arranged on the tank 3 to measure and thus regulate the height of the liquid column that is introduced into the hydraulic system of the machine when the valve 15 is opened.
Con el fin de calentar el liquido de lavado, el deposito 3 comprende un elemento de resistencia 19 energizado electricamente a traves de unos terminales externos 20. In order to heat the washing liquid, the tank 3 comprises a resistance element 19 electrically energized through external terminals 20.
Un filtro convencional, no mostrado, esta, asi mismo, insertado dentro del sistema hidraulico de la maquina, por ejemplo en el conducto de descarga 12 o, como alternativa, en el conducto de recirculacion 7. A conventional filter, not shown, is likewise inserted into the hydraulic system of the machine, for example in the discharge duct 12 or, alternatively, in the recirculation duct 7.
De acuerdo con la invencion, la fase de humidificacion de la colada situada dentro del tambor 2 es llevada a cabo mediante la activacion de la bomba de recirculacion 10 y la carga de una cantidad predeterminada de liquido dentro del sistema hidraulico de la maquina. In accordance with the invention, the humidification phase of the laundry located inside the drum 2 is carried out by activating the recirculation pump 10 and loading a predetermined amount of liquid into the hydraulic system of the machine.
Por consiguiente, la bomba de recirculacion 10 envia el liquido a las toberas 6 y 8 determinando que la colada sea humedecida, incluso con una pequefa cantidad de liquido. Therefore, the recirculation pump 10 sends the liquid to the nozzles 6 and 8 determining that the laundry is moistened, even with a small amount of liquid.
De modo preferente, esta cantidad de liquido es tal que puede ser establecido un nivel dinamico en el sistema que no exceda el plano horizontal A tangencial al borde 2a del tambor 2, cuando se considera en su punto mas bajo con respecto al eje geometrico de rotacion X - X. Preferably, this amount of liquid is such that a dynamic level can be established in the system that does not exceed the horizontal plane A tangential to the edge 2a of the drum 2, when considered at its lowest point with respect to the geometric axis of rotation X - X.
En consecuencia, de acuerdo con una caracteristica distintiva preferente de la invencion, si el tambor 2 se dispone simultaneamente en rotacion con el fin de humedecer la colada y difundir liquido dentro de ella, rota sin que exista un nivel de liquido en el tanque que pueda ofrecer resistencia a su movimiento. Accordingly, according to a preferred distinctive feature of the invention, if the drum 2 is arranged simultaneously in rotation in order to dampen the laundry and diffuse liquid within it, it rotates without there being a level of liquid in the tank that can Offer resistance to your movement.
De ello se sigue que el par de torsion y la energia requerida para que el motor accione el motor puede reducirse, dado que tanto durante la fase de humidificacion como durante las demas fases operativas de la maquina, la funcion de recirculacion tiene el nivel dinamico del liquido por debajo del plano A tangencial con respecto al borde 2a del tambor. It follows that the torque and energy required for the engine to drive the engine can be reduced, since both during the humidification phase and during the other operating phases of the machine, the recirculation function has the dynamic level of the liquid below the tangential plane A with respect to the edge 2a of the drum.
Esto se traduce en un considerable ahorro de energia y, asi mismo, hace posible reducir el tamafo del tambor, reduciendo con ello el par de torsion con el consecuente ahorro del coste. This translates into considerable energy savings and, likewise, makes it possible to reduce the size of the drum, thereby reducing the torque with the consequent cost savings.
5 La recirculacion durante la fase de humidificacion de la colada, de acuerdo con la invencion, hace posible que el sistema hidraulico de la lavadora para la colada sea cargado y, por tanto, utilizado incluso con una cantidad reducida de liquido con respecto a la cantidad estrictamente necesaria, de forma que el nivel dinamico no exceda o permanezca en el nivel del plano horizontal A tangencial respecto del borde 2a del tambor 2, con respecto al eje geometrico de rotacion X - X. 5 Recirculation during the humidification phase of the laundry, according to the invention, makes it possible for the hydraulic system of the laundry washing machine to be charged and therefore used even with a reduced amount of liquid with respect to the amount strictly necessary, so that the dynamic level does not exceed or remain at the level of the horizontal plane A tangential with respect to the edge 2a of the drum 2, with respect to the geometric axis of rotation X-X.
10 Las pruebas experimentales han mostrado que incluso cargando una cantidad reducida de liquido, por ejemplo una cantidad entre 400 y 600 mililitros, probablemente se traduzca, en una maquina con una capacidad de lavado de 9 �g de colada, en un nivel estatico que no exceda o sustancialmente coincida con el plano horizontal � tangencial con la porcion inferior del tanque en la parte mas baja de su perfil, es suficiente para humedecer de manera satisfactoria la colada dispuesta dentro del tanque debido al hecho de que dicha humidificacion se consigue mediante la 10 Experimental tests have shown that even loading a reduced amount of liquid, for example an amount between 400 and 600 milliliters, is likely to translate into a machine with a wash capacity of 9 g of laundry, at a static level that does not exceeds or substantially coincides with the horizontal plane � tangential with the lower portion of the tank in the lowest part of its profile, it is sufficient to successfully wet the laundry arranged inside the tank due to the fact that said humidification is achieved by
15 recirculacion del liquido a traves de la bomba 10. 15 recirculation of the liquid through the pump 10.
Asi mismo, se ha demostrado que, en la fase de humidificacion de la colada, sustancialmente �, de la cantidad total de liquido cargada dentro del sistema hidraulico de la maquina es recirculado. Likewise, it has been shown that, in the humidification phase of the laundry, substantially �, of the total amount of liquid loaded into the hydraulic system of the machine is recirculated.
La cantidad reducida de agua se traduce, asi mismo, en un ahorro considerable de la energia electrica utilizada para calentar el agua durante las sucesivas fases de lavado. The reduced amount of water also translates into a considerable saving of the electrical energy used to heat the water during the successive washing phases.
20 Se ha calculado que, en conjunto, puede conseguirse con la presente invencion una reduccion de aproximadamente un 25� de la energia consumida. It has been calculated that, as a whole, a reduction of approximately 25� of the energy consumed can be achieved with the present invention.
