Description
Maquina lavadora con una cubeta para la colada y un equipo de deteccion. La invencion se refiere a una maquina lavadora con una carcasa, con una cubeta para la colada fijada en la carcasa tal que puede vibrar, con un tambor dispuesto en su interior tal que puede girar con un eje de giro al menos aproximadamente horizontal, que puede accionarse mediante un motor y un equipo de deteccion para detectar la posicion y/o la situacion de la cubeta para la colada en la carcasa, que incluye un sensor de campo magnetico fijado a la carcasa con el correspondiente iman, que esta equipado para detectar la densidad de flujo y la direccion del campo magnetico que parte del iman. Washing machine with a laundry tray and detection equipment. The invention relates to a washing machine with a housing, with a laundry tray fixed in the housing such that it can vibrate, with a drum disposed therein such that it can rotate with an at least approximately horizontal axis of rotation, which can operated by means of a motor and a detection device to detect the position and / or the location of the casting bowl in the housing, which includes a magnetic field sensor attached to the housing with the corresponding magnet, which is equipped to detect the flux density and the direction of the magnetic field that starts from the magnet.
Las maquinas lavadoras de tambor conocidas poseen una cubeta para la colada suspendida en la carcasa tal que puede moverse vibrando, en la que esta apoyado un tambor que puede girar horizontalmente. Durante el funcionamiento de la maquina lavadora se pone a vibrar la cubeta para la colada debido a la caida de la colada o a desequilibrios, absorbiendose la vibracion lo mejor posible debido a la suspension elastica y a un amortiguamiento adicional y/o no transmitiendose a la carcasa o al suelo. No obstante, la vibracion de la cubeta para la colada debe vigilarse, para que cuando exista el peligro de vibraciones demasiado grandes se detenga el movimiento del lavado Known drum washing machines have a laundry bowl suspended in the housing such that it can move vibrating, on which a drum that can rotate horizontally is supported. During the operation of the washing machine the laundry tray is vibrated due to the fall of the laundry or imbalances, the vibration being absorbed as best as possible due to the elastic suspension and additional damping and / or not being transmitted to the housing or down. However, the vibration of the laundry tray must be monitored, so that when there is a danger of vibrations that are too large, the washing movement stops

Ademas puede detectarse en base al comportamiento en vibracion el peso de la colada or the centrifugation stage, so that they do not result due to the collision of the laundry tray with the housing or other component. In addition, the weight of the laundry can be detected based on the vibration behavior

Por el documento DE 20 2007 002 626 U1 se conoce una maquina lavadora que posee un equipo de deteccion para detectar la posicion y/o la situacion de la cubeta para la colada en la carcasa. El equipo de deteccion incluye un iman adosado a la cubeta para la colada que puede moverse y que se encuentra conectado operativamente con un sensor fijo respecto a la carcasa. El sensor esta equipado para determinar, ademas de la densidad de flujo del campo magnetico, tambien la direccion del campo magnetico. El sensor no esta aqui acoplado con el iman, por lo que puede suceder que en un movimiento desfavorable de la cubeta para la colada el iman abandone la zona operativa del sensor. Esto llevaria a detecciones incorrectas, por lo que podrian iniciarse medidas innecesarias para limitar el desequilibrio. En el peor de los casos podrian no detectarse a tiempo fuertes movimientos como tales, lo cual conduciria a indeseadas vibraciones fuertes. Ademas el sensor tiene una configuracion bastante costosa, ya que la zona de actuacion del propio sensor debe cubrir toda la trayectoria de desviacion de la cubeta para la colada. Por el documento DE 100 22 609 A1 se conoce la fijacion al perimetro de la cubeta para la colada de varios sensores, para lograr una deteccion exacta de movimientos o desviaciones de la cubeta para la colada debidos a desequilibrios. Esta configuracion es bastante costosa, debido a la interconexion de varios sensores. Por el documento EP 0 972 874 B1 se conoce una maquina lavadora con un tambor que gira verticalmente, en el que un dispositivo de deteccion para detectar vibraciones o desviaciones de la cubeta para la colada esta dispuesto en un elemento de sujecion, que presenta en el interior un sensor de campo magnetico y un iman. Aqui estan acoplado el iman con un elemento de sujecion con la cubeta para la colada, estando posicionado el sensor fijamente en el extremo del elemento de sujecion del lado de la carcasa. La configuracion del iman respecto al sensor esta realizada tal que solo puede detectarse la inte nsidad del cam po magnetico, pudiendo detectarse aqui solo variaciones de la distanc ia entre el im an y el se nsor. Movimientos pendulares laterales o mo vimientos de desplazamiento horizontales o movimientos de tambaleo con giro, que suceden a menudo en una maquina lavadora de tambor, no pueden detectarse. La invencion tiene asi como tarea basica proporcionar una maquina lavadora de tambor en la que la deteccion de desviaciones y ladeos de la cubeta para la colada se realice de manera sencilla y fiable. From DE 20 2007 002 626 U1, a washing machine is known which has a detection equipment to detect the position and / or the location of the laundry bowl in the housing. The detection equipment includes a magnet attached to the laundry tray that can move and is operatively connected to a fixed sensor with respect to the housing. The sensor is equipped to determine, in addition to the flux density of the magnetic field, also the direction of the magnetic field. The sensor is not here coupled with the magnet, so it can happen that in an unfavorable movement of the laundry tray the magnet leaves the sensor's operating area. This would lead to incorrect detections, so unnecessary measures could be initiated to limit the imbalance. In the worst case, strong movements as such might not be detected in time, which would lead to unwanted strong vibrations. In addition, the sensor has a rather expensive configuration, since the area of operation of the sensor itself must cover the entire path of deflection of the laundry tray. From document DE 100 22 609 A1 it is known to fix the perimeter of the tray for the casting of several sensors, to achieve an exact detection of movements or deviations of the tray for the laundry due to imbalances. This configuration is quite expensive, due to the interconnection of several sensors. From EP 0 972 874 B1 a washing machine with a drum that rotates vertically is known, in which a detection device for detecting vibrations or deviations from the laundry tray is arranged in a fastening element, which is present in the inside a magnetic field sensor and a magnet. Here the magnet is coupled with a clamping element with the laundry tray, the sensor being fixedly positioned at the end of the clamping element on the side of the housing. The configuration of the magnet with respect to the sensor is carried out such that only the intensity of the magnetic field can be detected, and only variations in the distance between the magnet and the sensor can be detected here. Lateral pendular movements or horizontal displacement movements or wobbling movements with rotation, which often occur in a drum washing machine, cannot be detected. The invention also has the basic task of providing a drum washing machine in which the detection of deviations and loops of the laundry tray is carried out simply and reliably.
En el marco de la inv encion se resue lve este probl ema mediante las caracteristicas de la reiv indicacion 1. Ventajosas configuraciones mejoradas y perfecci onamientos de la invencion resultan de las reivindicaciones dependientes 2 a 11. In the context of the invention, this problem is solved by means of the characteristics of claim 1. Advantageous improved configurations and improvements of the invention result from dependent claims 2 to 11.
Las ventajas que pueden lograrse mediante la invencion consisten en que se proporciona una deteccion muy exacta de la posicion y la situacion de la cubeta para la colada, con lo qu e pueden tomarse medidas selectivamente adaptadas para limitar las desviaciones de la cubeta para la colada. The advantages that can be achieved by the invention are that a very accurate detection of the position and location of the laundry tray is provided, whereby selectively adapted measures can be taken to limit the deviations of the laundry bowl.
En la maquina lavadora correspondiente a la invencion esta esencialmente fijado el sensor de campo magnetico a la carcasa, estando colocado el iman que interactua con el sensor de campo magnetico en un medio de sujecion, que mediante al menos un resorte esta acoplado con la cubeta para la c olada, encontrandose asi conectado operativamente con la misma. El medio de sujecion esta configurado para permitir un movimiento del iman respecto al sensor, estando preparado el resorte para transmitir un movimiento y/o o variacion de posicion de la cubeta para la colada al iman. Mediante esta configuracion se transmite el movimiento de la cubeta para la colada indirectamente al iman, conduciendo o limitando el medio de sujecion el iman siempre en la zona/a la zona optima de actuacion del sensor de campo magnetico. Debido a ello se evitan en muy amplia medida detecciones incorrectas, con lo que In the washing machine corresponding to the invention, the magnetic field sensor is essentially attached to the housing, the magnet that interacts with the magnetic field sensor being placed in a clamping means, which by means of at least one spring is coupled with the tray for the c olada, being thus operatively connected with it. The clamping means is configured to allow a movement of the magnet with respect to the sensor, the spring being prepared to transmit a movement and / or variation of position of the bowl for casting to the magnet. By means of this configuration, the movement of the tray for the casting is transmitted indirectly to the magnet, driving or limiting the clamping means the magnet always in the zone / to the optimum zone of actuation of the magnetic field sensor. Because of this, incorrect detections are avoided to a very large extent, so
resulta un funcionamiento fiable de la maquina lavadora, incluso en condiciones desfavorables de funcionamiento. Al ser las condiciones de funcionamiento optimas para el sensor, pueden detectarse y evaluarse mas rapidamente los valores de posicion. Tambien la carga del tambor, en funcion de la cual se detecta el descenso de la cubeta para la colada debido al peso, puede medirse o determinarse con este dispositivo de deteccion. Reliable operation of the washing machine results, even in unfavorable operating conditions. Since the operating conditions are optimal for the sensor, position values can be detected and evaluated more quickly. Also the load of the drum, depending on which the descent of the laundry bowl due to the weight is detected, can be measured or determined with this detection device.
En una ejecucion ventajosa esta equipado el medio de sujecion para permitir variaciones de distancia uniformes entre el iman y el sensor o movimientos de vuelco o de giro del iman respecto al sensor. Asi pueden detectarse movimientos de rotacion ymovimientos de traslacion en casi todas las direcciones espaciales que son relevantes para una cubeta para la co lada en una maquina lavadora. Los valores de medida detectados pueden entonces someterse a una transformacion matematica, para deducir cuales son los movimientos reales de la cubeta para la colada. Esta conversion se realiza de manera conveniente en un microcomputador del equipo de control. In an advantageous embodiment, the fastening means is equipped to allow uniform variations in distance between the magnet and the sensor or overturning or turning movements of the magnet with respect to the sensor. Thus, rotational movements and translation movements can be detected in almost all the spatial directions that are relevant for a laundry tray in a washing machine. The measured values detected can then undergo a mathematical transformation, to deduce what are the actual movements of the laundry tray. This conversion is conveniently performed in a microcomputer of the control equipment.
En un perfeccionamiento ventajoso esta preparado el medio de sujecion, interactuando con el resorte, para transmitir el movimi ento de la cu beta para l a col ada, d esmultiplicado, a l im an. La d esmultiplicacion posibilita l imitar desviaciones mayores de la cubeta para la colada, que se encuentran en la gama de 1 a 5 cm respecto a la posicion de reposo, a una zona de desviacion del iman en la gama de 1 a 10 mm, con lo que lazona operativa del sensor respectivo se mantiene correspondientemente reducida. In an advantageous refinement, the fastening means, interacting with the spring, are prepared to transmit the movement of the beta curtain for the collapse, multiplied, to the im. The multiplication makes it possible to imitate major deviations of the laundry tray, which are in the range of 1 to 5 cm from the resting position, to a zone of deviation of the magnet in the range of 1 to 10 mm, with what operational area of the respective sensor is kept correspondingly reduced.
Para proporcionar una libertad de movimientos optima al iman, esta dispuesto el sensor sobre una bola de una articulacion de rotula fij ada a la carc asa y e l med io d e suj ecion inc luye una c avidad que abarca al me nos parcialmente la bola, estando dispuesto el iman en el medio de sujecion distanciado del sensor. To provide optimum freedom of movement to the magnet, the sensor is arranged on a ball of a ball joint attached to the carcass and the clamping means includes a cavity that spans at least partially the ball, being arranged the magnet in the clamping means distanced from the sensor.
Para proporcionar la libertad de movimientos optima en cuanto a la variacion de la distancia entre el iman y el sensor es conveniente que el iman este fijado sobre un soporte que puede moverse en la pieza de sujecion, que mediante otro resorte interior al soporte proporciona el acoplamiento con el resorte que esta unido con la cubeta para la colada. Mediante la relacion entre la fuerza elastica o constantes elasticas del otro resorte y del resorte exterior que esta acoplado a la cubeta para la colada, se determina la desmultiplicacion en cuanto a la gama de distancias entre el iman y el sensor. To provide optimum freedom of movement in terms of the variation in the distance between the magnet and the sensor, it is convenient that the magnet is fixed on a support that can move in the clamping piece, which by means of another spring inside the support provides the coupling with the spring that is attached to the laundry tray. By means of the relationship between the elastic force or elastic constants of the other spring and of the outer spring that is coupled to the laundry tray, the multiplication is determined in terms of the range of distances between the magnet and the sensor.
En un perfeccionamiento ve ntajoso, en la posic ion del empl azamiento operativa de la ma quina lavadora, est a acoplado el extremo del resorte del lado de la cubeta para la colada a la zona anterior superior de la cubeta para la colada. Este punto de acoplamiento es especialmenteadecuado en una cubeta para la colada de una maquina lavadora de tambor, ya que casi todos los movimientos, al menos dos movimientos de rotacion y un movimiento de traslacion de la cubeta para la colada, tal como antes se ha descrito, realizan exactamente en esta zona tambien un movimiento que puede detectarse. In an advanced development, in the position of the operative installation of the washing machine, the end of the spring on the side of the laundry tray is coupled to the upper anterior area of the laundry tray. This coupling point is especially suitable in a laundry pan of a drum washing machine, since almost all movements, at least two rotational movements and a translation movement of the laundry tray, as described above , they also perform exactly in this area a movement that can be detected.
En maquinas lavadoras domesticas esta ampliamente difundida, por razon de costes, la practica de suspender la cubeta para la colada dentro de la carcasa en la partesuperior mediante resortesde sujecion, tal que puede moverse oscilando. En este tipo de suspension es ventajoso alojar el medio de sujecion sobre o dentro del resorte de sujecion tal que se proporcione una desmultiplicacion del movimiento de la cubeta para la colada respecto al iman. De esta maner a se p uede ah orrar el resort e de transmision, p ero d ebe r ealizarse la c orrespondiente transformacion matematica o evaluacion matematica de las serales de medida, ya que el resorte de sujecion usualmente no esta acoplado en la zona optima para la captacion en la cubeta para la colada. In domestic washing machines, it is widely disseminated, for reasons of cost, the practice of suspending the laundry tray inside the housing in the upper part by means of clamping springs, such that it can move oscillating. In this type of suspension, it is advantageous to house the fastening means on or inside the clamping spring such that there is a reduction in the movement of the bowl for casting with respect to the magnet. In this way, the transmission resort can be erased, but the corresponding mathematical transformation or mathematical evaluation of the measurement signals must be carried out, since the clamping spring is usually not coupled in the optimum area for the collection in the wash basin.
Para estas maquinas lavadoras esta realizado en un perfeccionamiento ventajoso el medio de sujecion como cuerpo de guia con forma de embolo, dispuesto en el interior del resorte de sujecion configurado como resorte de traccion, estando acoplado el cuerpo de guia con el resorte en una zona mas proxima al extremo del resorte de traccion del lado de la carcasa que al extremo del lado de la cubeta para la colada. El cuerpo de guia se encuentra por lo tanto en el interior del resorte de sujecion enrollado con forma de espiral. For these washing machines, the fastening means such as a plunger-shaped guide body, arranged inside the clamping spring configured as a traction spring, are carried out in an advantageous development, the guide body being coupled with the spring in a further area next to the end of the traction spring on the side of the housing than at the end of the side of the laundry tray. The guide body is therefore inside the spirally wound clamping spring.
El resorte de sujecion presenta en el lado de la carcasa un extremo curvado, que se sustenta sobre un apoyo curvado, para proporcionar movimientos en distintas direcciones de giro y de penduleo sobre el apoyo, estando fijado el sensor orientado en la direccion del resorte o bien del iman en la zona del apoyo. Asi se logra por el lado de la carcasa un acoplamiento del resorte de sujecion sencillo y fiable. The clamping spring has a curved end on the side of the housing, which is supported on a curved support, to provide movements in different directions of rotation and pendulousness on the support, the sensor being fixed oriented in the direction of the spring or of the magnet in the support zone. Thus, a simple and reliable fastening spring coupling is achieved on the housing side.
En un perfeccionamiento ventajoso esta configurado el cuerpo de guia, al menos por zonas, con el resorte sometido al efecto de rozamiento para amortiguar las oscilacionespropias del resorte. De esta manera mejora aun mas la exactitud de la medicion, ya que se evitan o al menos se reducen las mediciones incorrectas debidas a variaciones de distancia de corta duracion causadas por las oscilaciones propias del resorte. In an advantageous improvement, the guide body is configured, at least in areas, with the spring subjected to the friction effect to dampen the proper oscillations of the spring. This further improves the accuracy of the measurement, since incorrect measurements are avoided or at least reduced due to short-lived distance variations caused by the spring's own oscillations.
En otra ejecucion ventajosa presenta el dispositivo de captacion al menos otro sensor de campo magnetico con otro iman que se encuentra conectado operativamente con este sensor, estando acoplado el otro iman, distanciado del acoplamiento del primer iman, con la cubeta para el lavado. De esta manera puede lograrse de manera sencilla y con sensores simples una captacion muy precisa del movimiento de la cubetapara la colada, ya queal conocerse las condiciones de movimiento en ambos lugares de acoplamiento, es posible una transformacion matematica sencilla de las serales de medida. In another advantageous embodiment, the collection device has at least one other magnetic field sensor with another magnet that is operatively connected to this sensor, the other magnet being coupled, distanced from the coupling of the first magnet, with the wash basin. In this way, a very precise capture of the movement of the bucket for the laundry can be achieved in a simple manner and with simple sensors, since upon knowing the conditions of movement in both coupling places, a simple mathematical transformation of the measuring signals is possible.

La figura 1 muestra en una vista esquematica una maquina lavadora 1 que incluye una carcasa 2 con una cubeta para la colada 4 alojada en su interior tal que puede moverse vibrando. La cubeta para la colada 4 esta suspendida de la carcasa 2 mediante elementos de resorte 11 indicados someramente, tal que puede vibrar y su movimiento se amortigua mediante amortiguadores 12. En la cubeta para la colada 4 esta dispuesto un tambor 3 que puede girar con un eje de giro 6 al menos aproximadamente horizontal. El tambor 3 puede accionarse mediante un motor 5, con lo que se proporciona el movimiento de giro al lavar o al centrifugar. La maquina lavadora 1 incluye ademas un dispositivo de deteccion 7 para detectar la posicion y/o situacion y/o el movimiento de la cubeta para la colada 4 respecto a la carcasa 2. Un medio de sujecion 14 esta equipado para sujetar el iman 9 (figura 2), extendiendose el resorte 13 partiendo de este medio de sujecion para acoplar el medio de sujecion 14 o bien el iman 9 a la cubeta para la colada 4. El resorte 13 esta fijado en la zona anterior superior 18 a la pared de la cubeta para la colada en el lado exterior. Las indicaciones de direccion se refieren a la posicion de emplazamiento operativa de la maquina lavadora 1. En el ejemplo mostrado tiene la maquina lavadora 1 una abertura de carga frontal, pero el dispositivo de deteccion 7 puede utilizarse de la misma manera para una maquina lavadora de cara superior, por ejemplo una toplader. Figure 1 shows in a schematic view a washing machine 1 that includes a housing 2 with a laundry tray 4 housed therein such that it can move vibrating. The laundry tray 4 is suspended from the housing 2 by means of spring elements 11 indicated slightly, such that it can vibrate and its movement is damped by means of shock absorbers 12. In the laundry tray 4 there is arranged a drum 3 that can rotate with a axis of rotation 6 at least approximately horizontal. The drum 3 can be driven by a motor 5, thereby providing the rotational movement when washing or spinning. The washing machine 1 also includes a detection device 7 to detect the position and / or situation and / or the movement of the laundry tray 4 with respect to the housing 2. A fastening means 14 is equipped to hold the magnet 9 ( Figure 2), the spring 13 extending from this fastening means for attaching the fastening means 14 or the magnet 9 to the laundry tray 4. The spring 13 is fixed in the upper anterior area 18 to the wall of the laundry tray on the outer side. The direction indications refer to the operating location position of the washing machine 1. In the example shown, the washing machine 1 has a front loading opening, but the detection device 7 can be used in the same way for a washing machine upper face, for example a toplader.
La figura 2 muestra el dispositivo de captacion 7 en una vista esquematica de detalle. En esta ejecucion incluye el dispositivo de captacion 7 un sensor de campo magnetico 8, que esta fijado en una posicion fija respecto a la carcasa 2. Un iman 9 esta dispuesto en la zona operativa del sensor 8, que puede moverse mediante el resorte 13, viniendo originado el movimiento por la os cilacion o v ariacion de p osicion de la c ubeta para la c olada 4. L as indicaciones de la flecha x, y, z indican que los movimientos de traslacion de la cubeta para la colada en al menos practicamente las tres direcciones espaciales da lugar a movimientos correspondientemente evaluables del iman 9 respecto al sensor de campo magnetico 8, pudiendo detectarse aqui el movimiento de traslacion en direccion vertical ytrans. Tambien se transmiten movimientos de rotacion xrot o zrot de la cubeta para la colada 4, desmultiplicados, al iman 9, con lo que mediante una transformacion matematica de la seral del sensor captada puede detectarse la posicion real y el movimiento de la cubeta para la colada 4. Para ello s e utiliza el microcomputador del equipo de control 22 (fig. 1), al que se llevan las serales del sensor 8. La transformacion de las serales del sensor en datos evaluables por el sistema de control 2 2 puede realizarse alternativamente tambien mediante un circuito electronico separado o un circuito de microprocesador separado, que preferiblemente esta constituido como unidad con el sensor 8. Figure 2 shows the collection device 7 in a schematic detail view. In this embodiment, the pick-up device 7 includes a magnetic field sensor 8, which is fixed in a fixed position with respect to the housing 2. A magnet 9 is arranged in the operating area of the sensor 8, which can be moved by the spring 13, the movement is caused by the oscillation of the position of the cuvette for the oval 4. The indications of the arrow x, y, z indicate that the movements of translation of the cuvette for at least practically the three spatial directions give rise to correspondingly evaluable movements of the magnet 9 with respect to the magnetic field sensor 8, the translational movement in the vertical direction and transients can be detected here. Xrot or zrot rotation movements of the laundry tray 4, which are multiplied, are also transmitted to the magnet 9, whereby the actual position and the movement of the laundry tray can be detected by a mathematical transformation of the sensor 4. For this purpose, the microcomputer of the control equipment 22 (fig. 1) is used, to which the sensor signals are carried 8. The transformation of the sensor signals into data evaluable by the control system 2 2 can alternatively also be carried out by a separate electronic circuit or a separate microprocessor circuit, which is preferably constituted as a unit with the sensor 8.
La figura 3 muestra la ejecucion de la maquina lavadora 1 con otro ac oplamiento del iman con la cubeta para la colada 4. Al igual que en el primer ejemplo, esta suspendida la cubeta para la colada 4 mediante resortes de sujecion 11 dentro de la carcasa 2 tal que puede vibrar. Para amortiguar las oscilaciones estan fijadas a la cubeta para la colada 4 amortiguadores 12, que se apoyan contra la parte inferior de la carcasa 2. El dispositivo de deteccion 7 incluye un medio de guia 19 con forma de embolo, que sustenta el iman 9 (figura 4). El medio de guia 19 con el iman esta dispuesto dentro del resorte de sujecion 11, configurado como resorte en esp iral. Para que l a captacion sea exacta, incluye el dispositivo de deteccion 7 en otra ejecucion, en otro resorte de sujecion 11a, un segundo medio de guia 19a, que sustenta otro iman 9a. Cada iman 9 lleva asociado el correspondiente sensor 8, 8a separado. L as seral es ge neradas por ca da sens or 8, 8a se ev aluan corresp ondientemente, pa ra calcu lar o determinar a partir de ello la posicion momentanea real en cada caso, asi como el movimiento de la cubeta para la colada 4. Figure 3 shows the execution of the washing machine 1 with another magnetization of the magnet with the laundry tray 4. As in the first example, the laundry tray 4 is suspended by means of holding springs 11 inside the housing 2 such that it can vibrate. To dampen the oscillations, 4 dampers 12, which are supported against the lower part of the housing 2, are fixed to the laundry tray. The detection device 7 includes a guide means 19 in the form of a plunger, which supports the magnet 9 ( figure 4). The guide means 19 with the magnet is disposed within the clamping spring 11, configured as a spiral spring. So that the acquisition is accurate, it includes the detection device 7 in another embodiment, in another clamping spring 11a, a second guide means 19a, which supports another magnet 9a. Each magnet 9 is associated with the corresponding sensor 8, 8a separately. The signal is generated by each sensor 8, 8a correspondingly, to calculate or determine the actual momentary position in each case, as well as the movement of the laundry tray 4.
La figura 4 muestra el dispositivo de captacion 7 para esta ejecucion. El extremo 20 del lado dela carcasa del resorte de sujecion 11 esta configurado curvado o con forma de arco, sustentan dose en un a poyo 21 curvado. De esta manera puede seguir el resorte un movimiento de giro de la cubeta para la colada (figura 3), sin que se doble el propio resorte en espiral. Dentro de las espiras del resorte esta dispuesto el cuerpo de guia 19 con forma de embolo, que sustenta en su extremo orientado hacia el apoyo 21 del lado de la carcasa el iman 9. En el apoyo 21 esta fijado el sensor de campo magnetico 8 orientado hacia el resorte o bien hacia el iman 9, encontrandose el mismo en este ejemplo sobre una placa de circuitos 23, que en este ejemplo sustenta ademas un circuito electronico o un circuito de microprocesador para la conversion o transformacion de las serales de medida. El cuerpo de guia 19 esta alojado, sometido al efecto del rozamiento, en el res orte de sujecion 11, con lo que se amortiguan o impiden oscilaciones propias del resorte 11 en la zona del iman 9, evitandose asi indeseadas mediciones incorrectas. El cuerpo deguia 19 esta fijado enel lugar de fijacion 25 al resorte 11, encontrandose el lugar de fijacion 25 mas proximo al extremo 20 del lado de la carcasa que al extremo 24 del lado de la cubeta de lavado. No obstante, para la desmultiplicacion d el movim iento no es d ecisiva s olamente l a dis posicion espacial, sino l a rel acion e ntre la trayectoria mas pequera del resorte entre el lugar de fijacion 25 y el extremo 20 del lado de la carcasa y la trayectoria mas grande del resorte del lugar de fijacion 25 hasta el extremo 24 del lado de la cubeta para la colada. Figure 4 shows the collection device 7 for this execution. The end 20 of the housing side of the clamping spring 11 is curved or arc-shaped, supported by a curved pole 21. In this way, the spring can follow a rotational movement of the laundry tray (figure 3), without spiraling the spring itself. Inside the windings of the spring is the guide body 19 in the form of a plunger, which supports the magnet 9 at its end oriented towards the support 21 on the side of the housing. On the support 21 the oriented magnetic field sensor 8 is fixed towards the spring or towards the magnet 9, the same being found in this example on a circuit board 23, which in this example also supports an electronic circuit or a microprocessor circuit for the conversion or transformation of the measurement signals. The guide body 19 is housed, subjected to the effect of friction, in the clamping spring 11, thereby damping or preventing oscillations characteristic of the spring 11 in the area of the magnet 9, thus avoiding undesired incorrect measurements. The guide body 19 is fixed at the fixing place 25 to the spring 11, the fixing place 25 being closer to the end 20 of the side of the housing than to the end 24 of the side of the wash basin. However, for the demultiplication of the movement, spatial displacement is not only decisive, but the relationship between the smallest path of the spring between the fixing location 25 and the end 20 of the housing side and the larger spring path from the fixing place 25 to the end 24 of the side of the laundry tray.
