Description
Máquina lavadora y/o secadora de ropa con dispositivo de control mejorado.Washing machine and / or clothes dryer with Enhanced control device
El presente invento se refiere a una máquina lavadora y/o secadora de ropa, particularmente de tipo doméstico, provista de un dispositivo de control mejorado que permite detectar, al menos, un parámetro funcional, como la humedad, la temperatura y similares, con el fin de hacer funcionar la máquina en consecuencia.The present invention relates to a machine clothes washer and / or dryer, particularly domestic type, provided with an improved control device that allows to detect, at least one functional parameter, such as humidity, temperature and similar, in order to operate the machine in consequence.
Es sabido, por ejemplo, que una máquina lavadora y/o secadora de ropa está provista, normalmente, de un sistema para medir la humedad de las prendas contenidas en el tambor giratorio, con el fin de detener el funcionamiento de la máquina cuando la ropa está suficientemente seca.It is known, for example, that a washing machine and / or clothes dryer is normally provided with a system for measure the humidity of the garments contained in the rotating drum, in order to stop the operation of the machine when clothes It is dry enough.
Un sistema ampliamente utilizado para controlar la humedad en una máquina de este tipo, debido a su buen comportamiento, es un denominado "medidor de conductividad". Sustancialmente, el tambor giratorio está dividido en dos partes, eléctricamente aisladas una de otra. Se mide la resistencia eléctrica entre estas dos partes giratorias. El sistema de medición comprende un circuito electrónico y dos escobillas, realizando dichas escobillas una conexión eléctrica de los dos "medios tambores" con el circuito de medición. Las dos escobillas son estacionarias y los medios tambores giran contra ellas.A widely used system to control the humidity in a machine of this type, due to its good behavior, is a so-called "conductivity meter". Substantially, the rotating drum is divided into two parts, electrically isolated from each other. Resistance is measured electric between these two rotating parts. Measuring system It comprises an electronic circuit and two brushes, making said brushes an electrical connection of the two "means drums "with the measuring circuit. The two brushes are stationary and half drums rotate against them.
El punto débil del sistema medidor de conductividad, por distintas razones, está representado por las escobillas. La vida útil de las escobillas es limitada debido a la fricción mecánica que se genera durante la rotación del tambor; en consecuencia, el alto coste de mantenimiento es relevante. Además, se genera un molesto ruido debido a la fricción de las escobillas contra el tambor.The weak point of the measuring system conductivity, for different reasons, is represented by brushes The life of the brushes is limited due to the mechanical friction that is generated during drum rotation; in Consequently, the high maintenance cost is relevant. Further, annoying noise is generated due to the friction of the brushes Against the drum
Sin embargo, las escobillas del actual sistema medidor de conductividad son necesarias, ya que no es posible poner una placa electrónica directamente en el tambor giratorio. Ello se debe a que la placa electrónica tiene que recibir alimentación eléctrica y comunicarse (de forma inalámbrica, mediante un sistema de RF o de IR) con la placa de control de la máquina.However, the brushes of the current system conductivity meter are necessary, since it is not possible to put an electronic board directly on the rotating drum. Them and because the electronic board has to receive power electrical and communicate (wirelessly, through a system RF or IR) with the machine control board.

Los valores medidos son transmitidos entre el perceptor y el lector a través de un enlace inalámbrico. Los medios de control se basan en la tecnología de los transpondedores o, como alternativa, en medios mecánicos genéricos accionados por la rotación del tambor.EP 1 321 563 describes a machine clothes washer and / or dryer provided with a measuring device to determine at least one parameter of the clothing or air of drying contained in the rotating drum, which has a perceptor of measurement mounted on the rotating drum, which cooperates with a reader stationary.

- la figura 4 representa esquemáticamente una realización del invento alternativa con respecto a la de la figura 2.- Figure 4 schematically represents a embodiment of the alternative invention with respect to that of the figure 2.
La solución técnica del presente invento se basa en el uso de un generador de energía eléctrica que puede asociarse directamente al tambor de una máquina lavadora y/o secadora de ropa. El generador puede alimentar a una placa electrónica colocada directamente en el tambor y adecuada para medir la conductividad de las prendas contenidas en el tambor, y para comunicarse con la placa de control de la máquina. La placa electrónica comprende un microordenador de tipo conocido (no mostrado en los dibujos).The technical solution of the present invention is based in the use of an electric power generator that can be associated directly to the drum of a washing machine and / or clothes dryer. The generator can feed a placed electronic board directly on the drum and suitable for measuring the conductivity of the garments contained in the drum, and to communicate with the machine control board. The electronic board comprises a microcomputer of known type (not shown in the drawings).
Ventajosamente, el generador 6 de energía eléctrica (figura 1) consiste en una parte mecánica y una parte eléctrica. La parte mecánica comprende un imán permanente 10 montado para deslizar libremente dentro de un tubo 12 hecho de material no conductor, como plástico. La parte eléctrica comprende una bobina 14 que está arrollada por fuera del tubo 12 y conectada con una fuente de alimentación 16 en modo conmutado (SMPS) a través de un circuito eléctrico que comprende un rectificador 18 de puente y un condensador 20. Cuando el imán permanente 10 atraviesa la bobina 14, se genera un voltaje en la propia bobina.Advantageously, the power generator 6 electric (figure 1) consists of a mechanical part and a part electric The mechanical part comprises a permanent magnet 10 mounted to slide freely into a tube 12 made of non-material conductor, like plastic. The electrical part comprises a coil 14 which is wound outside the tube 12 and connected to a source power supply 16 in switched mode (SMPS) through a circuit electric comprising a bridge rectifier 18 and a capacitor 20. When permanent magnet 10 passes through coil 14, A voltage is generated in the coil itself.
Como consecuencia, el circuito eléctrico genera un voltaje de corriente continua (por ejemplo, 5 V) que es alimentado a la placa de control de la máquina (no mostrada). El valor de la corriente (y, por ello, la potencia relevante) dependerá de la característica del imán y de su velocidad, así como de la característica eléctrica de la bobina.As a consequence, the electrical circuit generates a direct current voltage (for example, 5 V) which is fed to the machine control board (not shown). He value of the current (and, therefore, the relevant power) it will depend on the characteristic of the magnet and its speed, as well as of the electrical characteristic of the coil.
Naturalmente, el rectificador 18 de puente puede ser sustituido por cualesquiera medios equivalentes, por ejemplo un único rectificador que proporcione rectificación de media onda.Naturally, bridge rectifier 18 can be replaced by any equivalent means, for example a single rectifier that provides half wave rectification.
La placa de control que contiene el generador de energía eléctrica, descrito con referencia a la figura 1, podría asociarse directamente al tambor 22, por ejemplo, fijarse en la superficie externa del lado trasero (figura 2). El tubo 12 es recto y su sección puede tener cualquier configuración, siendo preferiblemente circular; naturalmente, la sección del imán 10 debe tener la misma configuración.The control board containing the generator electric power, described with reference to figure 1, could associate directly with drum 22, for example, look at the outer surface of the rear side (figure 2). The tube 12 is straight and its section can have any configuration, being preferably circular; naturally, the section of the magnet 10 must Have the same configuration.
Durante la rotación del tambor (figura 3), el imán permanente 10 se mueve en vaivén dentro del tubo 12, dos veces por cada revolución completa del tambor. En consecuencia, en la bobina 14 se generan señales de voltaje alternas en cada paso del imán 10 a través de la propia bobina.During drum rotation (figure 3), the permanent magnet 10 moves reciprocating inside tube 12, twice for every complete revolution of the drum. Consequently, in the coil 14 alternate voltage signals are generated at each step of the 10 magnet through the coil itself.
Las señales son tratadas por el SMPS 16 del circuito eléctrico asociado y son transformadas en señales de voltaje de corriente continua, que son enviadas a la placa de control de la máquina, para llevar a la práctica las funciones correspondientes.The signals are processed by SMPS 16 of the associated electrical circuit and are transformed into signals from DC voltage, which are sent to the board Machine control, to implement the functions corresponding.
La comunicación de la información desde la placa electrónica, asociada al tambor, a la placa de control de la máquina, puede llevarse a la práctica en una de diferentes formas bien conocidas, como inalámbrica o sistemas de RF o IR.Information communication from the board electronics, associated to the drum, to the control board of the machine, can be implemented in one of different ways Well known, such as wireless or RF or IR systems.
Entonces, puede establecerse una correlación entre el número de revoluciones del tambor y el grado de humedad de la ropa, teniendo también en cuenta otros parámetros conocidos, como el tipo de ropa, la cantidad de la misma, su temperatura, etc. La señal eléctrica emitida por el generador de energía eléctrica es tratada en la placa de control de la máquina y comparada con datos prefijados, en forma usual, por medio del microordenador en ella incorporado.Then, a correlation can be established between the number of revolutions of the drum and the degree of humidity of clothing, also taking into account other known parameters, such as the type of clothing, the amount of it, its temperature, etc. The electrical signal emitted by the electric power generator is treated on the machine control board and compared with data preset, in the usual way, by means of the microcomputer in it Incorporated.
Una realización alternativa del presente invento se representa esquemáticamente en la figura 4. En ella, el imán permanente 10 está incorporado dentro de un tubo circular 12, y una pluralidad de bobinas 14 están equiespaciadas, recíprocamente, en la superficie externa del tubo 12. En este caso, durante la rotación del tambor 22, el imán 10 gira dentro del tubo circular 12 pasando sucesivamente a través de las bobinas 14.An alternative embodiment of the present invention it is schematically represented in figure 4. In it, the magnet permanent 10 is incorporated into a circular tube 12, and a plurality of coils 14 are equally spaced, reciprocally, in the outer surface of the tube 12. In this case, during the rotation of the drum 22, the magnet 10 rotates inside the circular tube 12 passing successively through the coils 14.
De preferencia, la longitud axial de cada bobina 14 no puede ser mayor que la del imán 10, y la distancia axial entre dos bobinas contiguas debe ser, al menos, igual a la longitud axial del imán.Preferably, the axial length of each coil 14 cannot be greater than that of magnet 10, and axial distance between two adjacent coils must be at least equal to the length axial of the magnet.
Ambas soluciones expuestas ofrecen, también, la posibilidad de medir la velocidad del tambor analizando las características (distancia entre impulsos sucesivos, período de los impulsos, etc.) del voltaje de salida. Esto podría hacerlo el mismo microordenador que mide la conductividad y gestiona la comunicación con la placa de control de la máquina.Both exposed solutions also offer the possibility of measuring drum speed by analyzing the characteristics (distance between successive pulses, period of impulses, etc.) of the output voltage. This could do the same. microcomputer that measures conductivity and manages communication With the machine control board.
Dicha medición resulta útil, por ejemplo, para detectar posibles averías de la máquina, como una rotura del motor o de la correa que hace girar el tambor.Such measurement is useful, for example, for detect possible machine breakdowns, such as engine breakage or the belt that rotates the drum.
Un experto en la técnica puede comprender inmediatamente que el generador de energía eléctrica que se utiliza para medir la cantidad de humedad de la ropa puede emplearse, también, para detectar y controlar otros parámetros funcionales de la máquina, siempre que dicha máquina esté equipada con un componente giratorio.One skilled in the art can understand immediately that the electric power generator that is used to measure the amount of moisture in clothing can be used, also, to detect and control other functional parameters of the machine, provided that said machine is equipped with a rotating component
