Por razones de costes se utilizan en máquinas lavadoras y secadoras de ropa en medida creciente recipientes de plástico para la colada. Tales máquinas lavadoras son conocidas por ejemplo por la DE 298 21 140 U1. Se conoce además la disposición de sensores de temperatura dentro del recipiente para la colada en máquinas lavadoras para regular la temperatura del líquido de lavado.For cost reasons they are used in machines washing machines and clothes dryers in growing containers plastic for laundry. Such washing machines are known for example by DE 298 21 140 U1. The provision of temperature sensors inside the laundry container in washing machines to regulate the liquid temperature of washed.
Por la JP 04285591 A (Patent Abstracts of Japan) se conoce una lavadora con un tambor que puede girar horizontalmente dentro de un recipiente, en el que el tambor debe ser protegido frente a deformaciones. El tambor giratorio que se utiliza en esta máquina lavadora puede reblandecerse por la acción del agua caliente, con lo que puede deformarse durante el centrifugado. Esto se evita deteniendo el proceso de centrifugado cuando se sobrepasa la temperatura del agua o la temperatura del tambor.By JP 04285591 A (Patent Abstracts of Japan) a washing machine with a drum that can rotate horizontally is known inside a container, in which the drum must be protected against deformations. The rotating drum that is used in this washing machine can be softened by the action of water hot, so it can deform during centrifugation. This it is avoided by stopping the spin process when it is exceeded water temperature or drum temperature.
Por la JP 04117998 A (Patent Abstracts of Japan) se conoce una máquina lavadora con un tambor que puede girar horizontalmente dentro de un recipiente, en el que el tambor debe ser protegido frente a deformaciones. El tambor giratorio que se utiliza en esta máquina lavadora puede reblandecerse por la acción del agua caliente, con lo que puede deformarse durante el centrifugado. Cuando la temperatura del tambor es demasiado elevada, se refrigera el tambor mediante aire de soplante aportado, girando entonces el tambor lentamente durante la refrigeración. Una vez se llega por debajo del valor límite para la temperatura del tambor, prosigue el proceso de centrifugado.By JP 04117998 A (Patent Abstracts of Japan) a washing machine with a drum that can rotate is known horizontally inside a container, in which the drum must Be protected against deformations. The rotating drum that used in this washing machine can be softened by the action of hot water, which can deform during centrifuged When the drum temperature is too high, the drum is cooled by supplied blower air, rotating Then the drum slowly during cooling.

Por la memoria de patente US 5,394,582 se conoce un procedimiento para calentar la colada en una máquina lavadora en el que se evalúan múltiples sensores para detectar la temperatura de la colada o la temperatura de un equipo calefactor. Al respecto, se protege la colada y el equipo calefactor frente a sobrecalentamiento.US Pat. No. 5,394,582 is known as a procedure for heating the laundry in a washing machine in which is evaluated multiple sensors to detect the temperature of the laundry or the temperature of a heating equipment. In this regard, it protects laundry and heating equipment against overheating
Por el documento de publicación japonés JP 2000279684 A (Patent Abstracts of Japan) se conoce una secadora de ropa con un tambor que gira alrededor de un eje vertical, en el que se evitan daños al tejido de la colada durante el proceso de secado. Al respecto, se ajusta el aire calentado a su temperatura por parte de una unidad de control, tal que se mantiene un valor especificado.By the Japanese JP publication document 2000279684 A (Patent Abstracts of Japan) is known a dryer clothes with a drum that rotates around a vertical axis, in which damage to the laundry fabric is avoided during the drying process. In this regard, the heated air is adjusted to its temperature by of a control unit, such that a value is maintained specified.
Los materiales económicos de plástico utilizados en recipientes para la colada permiten sólo una carga limitada durante el centrifugado, al sobrepasar la cual se llega a daños permanentes. Esto es válido especialmente para puntos fuertemente cargados mecánicamente, como la parte posterior del recipiente para la colada, en particular la transición de un cubo de apoyo inyectado al plástico o el cordón de unión de dos mitades de recipientes para la colada. Los valores límite de servicio dependen por un lado de parámetros del material y de la geometría del recipiente para la colada. El influir sobre estas magnitudes mediante espesores de pared superiores o un plástico más valioso, daría lugar a costes crecientes y otros inconvenientes funcionales, como por ejemplo inferiores trayectorias de oscilación libre y la inferior capacidad de absorción de desequilibrios que ello implicaría, mayor consumo de energía y otros.The economical plastic materials used in laundry containers allow only a limited load during centrifugation, when exceeding which damage is reached permanent This is especially true for strongly points. mechanically loaded, such as the back of the container for laundry, in particular the transition from an injected support hub to the plastic or the connecting cord of two halves of containers for the laundry The service limit values depend on the one hand of parameters of the material and the geometry of the container for wash. Influencing these magnitudes through thicknesses of higher wall or more valuable plastic, would result in costs increasing and other functional problems, such as Lower free swing paths and lower capacity of absorption of imbalances that would imply, greater consumption of Energy and others.
Por otro lado, dependen los valores límite de servicio directamente de las fuerzas que actúan sobre el recipiente para la colada. Una posibilidad de reducir las mismas es por ejemplo la vigilancia del desequilibrio, que permite elevadas velocidades de centrifugado sólo para unos desequilibrios mínimos. Esto da lugar en la práctica a claras limitaciones durante la utilización.On the other hand, the limit values of service directly from the forces acting on the vessel for laundry. One possibility of reducing them is for example imbalance monitoring, which allows high speeds of centrifuged only for minimal imbalances. This results in practice to clear limitations during use.
La invención se formula así el problema de dar a conocer un procedimiento para el control del programa de lavado de una máquina lavadora del tipo indicado al principio, en el cual se minimicen las limitaciones predeterminadas por el límite de la carga para el recipiente de plástico para la colada, sin variación de la geometría de las piezas.The invention thus formulates the problem of giving know a procedure to control the washing program of a washing machine of the type indicated at the beginning, in which minimize predetermined limitations by load limit for the plastic container for laundry, without variation of the geometry of the pieces.
Este problema se resuelve en el marco de la invención mediante un procedimiento con las particularidades de las reivindicaciones independientes 1 a 4. Ventajosas mejoras y perfeccionamientos del procedimiento de la reivindicación 1 resultan de la siguiente reivindicación secundaria 2. Otra reivindicación 3 da a conocer una máquina lavadora adecuada para realizar un procedimiento según las reivindicaciones 1 ó 2.This problem is solved within the framework of the invention by means of a procedure with the particularities of the independent claims 1 to 4. Advantageous improvements and refinements of the method of claim 1 result from the following secondary claim 2. Other claim 3 discloses a washing machine suitable for Perform a method according to claims 1 or 2.
Las ventajas que pueden alcanzarse con la invención resultan del conocimiento de que la temperatura de un recipiente de plástico para la colada interviene como otra magnitud influyente importante en los límites de carga del material. Puesto que la temperatura del material se ve influida ante todo, para unos parámetros de geometría y material dados, por la temperatura del líquido de lavado, la temperatura ambiente, la duración del programa, la frecuencia de uso, el calentamiento del cojinete del tambor, la cantidad de agua y el calentamiento del material debido a las solicitaciones mecánicas y puesto que hoy día debido al bajo ensuciamiento de la colada los programas de lavado se realizan con prescripciones de tiempo y de temperatura para el líquido cada vez menores por parte del usuario, deben impedirse simplemente condiciones extremas (elevada temperatura del material y a la vez elevada carga mecánica). Puesto que éstas sólo se presentan ocasionalmente, pueden realizarse mediante la utilización de uno de los procedimientos configurados según la invención o mediante una combinación de los mismos, incluso en máquinas lavadoras con recipientes de plástico para la colada, con un material comparativamente económico, programas de lavado con elevadas velocidades de giro y suficientes desequilibrios sin que exista el peligro de daños y de la limitación en la utilización usual o sean necesarias las correspondientes medidas constructivas como refuerzo o modificaciones en el material.The advantages that can be achieved with the invention result from the knowledge that the temperature of a plastic laundry container intervenes as another magnitude important influence on the load limits of the material. Market Stall that the temperature of the material is influenced first and foremost, for some given geometry and material parameters, by the temperature of the washing liquid, room temperature, duration of program, frequency of use, heating of the bearing drum, the amount of water and the heating of the material due to mechanical solicitations and since today due to the low laundry fouling washing programs are carried out with time and temperature prescriptions for the liquid each time minors by the user, they should simply be prevented extreme conditions (high temperature of the material and at the same time high mechanical load). Since these only appear occasionally, they can be done by using one of the procedures configured according to the invention or by a combination thereof, even in washing machines with plastic containers for laundry, with a material comparatively economical, high wash programs turning speeds and sufficient imbalances without the existence of danger of damage and limitation in usual use or the corresponding constructive measures are necessary as reinforcement or modifications in the material.
Un ejemplo de ejecución de la invención se describe más en detalle a continuación. Una máquina lavadora para realizar el procedimiento correspondiente a la invención posee un recipiente para la colada fabricado de plástico en un procedimiento de fundición inyectada. En el mismo se apoya de manera que puede girar un tambor para alojar la colada y es accionado mediante un motor con distintas velocidades de giro de lavado y de centrifugado. La máquina lavadora posee un equipo de control para prescribir las velocidades de giro del motor y otros parámetros de programa. Una máquina lavadora como la indicada se conoce por ejemplo por la DE 298 21 140 U1 citada al principio y por tanto no se ha representado mediante dibujos ni se ha descrito extensamente.An exemplary embodiment of the invention is describe more in detail below. A washing machine for performing the procedure corresponding to the invention has a laundry container made of plastic in one procedure Injected cast iron. It relies on it so that it can rotate a drum to house the laundry and is operated by a motor with different speeds of rotation of wash and spin. The washing machine has a control equipment to prescribe the engine rotation speeds and other program parameters. A washing machine as indicated is known for example by the DE 298 21 140 U1 cited at the beginning and therefore has not been represented by drawings or described extensively.
Se propone una vigilancia directa o indirecta de la temperatura de puntos especialmente cargados de un recipiente de plástico para la colada, para cuando se presentan estados críticos (temperaturas de material demasiado elevadas) reducir la carga o la temperatura y con ello proteger el recipiente para la colada. Esto puede realizarse básicamente por dos vías:Direct or indirect surveillance of the temperature of specially charged points of a container of plastic for laundry, when critical conditions occur (material temperatures too high) reduce the load or temperature and thereby protect the laundry container. This It can be done basically in two ways:
Mediante el cálculo o ensayos se averiguan los puntos especialmente cargados y puestos en peligro de un recipiente de plástico para la colada. En uno o varios de estos puntos se aloja un sensor de medición de temperatura, cuya señal es captada y evaluada por una unidad de medida y control. En función de los valores límites archivados en un ordenador y de los valores de proceso desequilibrio, velocidad de giro y tiempo de centrifugado, se realizan modificaciones en el proceso de lavado que llevan la temperatura de las piezas a la zona admisible. Las variaciones de este tipo pueden ser, entre otras, una reducción de la velocidad de giro, acortamientos del programa, redistribuciones de la colada, entrada de agua fresca, limitación de la temperatura de la colada, lo cual da lugar a la vez a una temperatura inferior o a una velocidad inferior de aumento de la temperatura.The calculation or tests determine the specially loaded and endangered points of a container of plastic for laundry. One or more of these points is housed a temperature measuring sensor, whose signal is captured and evaluated by a unit of measurement and control. Depending on the limit values archived on a computer and the values of imbalance process, spin speed and spin time, modifications are made to the washing process that carry the temperature of the parts to the permissible zone. Variations of this type may be, among others, a reduction in the speed of turn, program shortenings, redistributions of the laundry, fresh water inlet, limitation of laundry temperature, which results both at a lower temperature or at a lower speed of temperature rise.
Uno o varios sensores pueden colocarse también en otro lugar del recipiente para la colada, cuando las mediciones allí permiten conclusiones fiables relativas a la temperatura en los puntos críticos.One or more sensors can also be placed elsewhere in the laundry container, when measurements there they allow reliable conclusions regarding the temperature in the critical points.
También es posible realizar a partir de los datos del proceso de lavado (velocidad de giro, cantidad de agua, carga, tiempo, temperatura, etc.), de la temperatura ambiente, de los datos del material y de la geometría de las piezas, con sensores (sensor de temperatura de la colada, sensor de carga, etc.) existentes en la máquina lavadora automática, un cálculo de la temperatura en puntos críticos del recipiente para la colada y emprender entonces reacciones tal como se ha descrito antes.It is also possible to perform from washing process data (speed of rotation, amount of water, load, time, temperature, etc.), of the ambient temperature, of material and part geometry data, with sensors (laundry temperature sensor, load sensor, etc.) existing in the automatic washing machine, a calculation of the temperature at critical points of the laundry container and then undertake reactions as described above.
También la combinación de medición de temperatura directa e indirecta es razonable, para tener suficiente seguridad en el caso de fallo de un sistema.Also the measurement combination of Direct and indirect temperature is reasonable, to have enough security in the event of a system failure.
Además, se propone realizar una prueba continua del funcionamiento de los sensores cuando se utilizan uno o varios sensores, realizando y comparando antes del comienzo de un nuevo programa de lavado, tras un tiempo de parada suficientemente largo, la medición de temperatura con los sensores adicionales y el sensor de la temperatura de la colada utilizado en el proceso de lavado.In addition, it is proposed to carry out a continuous test of the operation of the sensors when one or more are used sensors, performing and comparing before the start of a new washing program, after a sufficiently long stop time, Temperature measurement with additional sensors and sensor of the laundry temperature used in the process of washed.
