Abstract

Panel para la cubierta de un aparato, con un cuerpo de soporte (1) provisto de un escotadura (5) y un inserto (2) incluido en la escotadura (5), caracterizado por que el inserto consiste esencialmente en un material de plástico permeable a infrarrojos y por que el inserto (2) se fija en la escotadura (5) por soldadura o por activación de una capa localizada entre el cuerpo de soporte (1) y el inserto (2) de un adhesivo termoactivable por radiación infrarroja.

Description

La presente invención se refiere a un panel para la cubierta de un aparato de acuerdo con el preámbulo de la reivindicación 1, particularmente una cubierta de un aparato doméstico de tipo armario tal como, por ejemplo, un congelador o un frigorífico, así como a un método para su producción.
Un panel de este tipo se describe, por ejemplo, en el documento DE 100 37 250 A1. Esencialmente está compuesto por un cuerpo de soporte hueco de plástico, que se proporciona para alojar en el mismo un circuito de control del aparato y que está provisto de una escotadura en el lado frontal, en la que se incluye una placa o un inserto. Esta placa o inserto de material plano de plástico se puede producir con una baja complejidad en una pluralidad de variantes, de tal forma que se pueden realizar paneles individuales para una pluralidad de diferentes modelos de aparatos por combinación de diferentes insertos con un mismo cuerpo de soporte.
Ya que los diversos tipos de circuitos de control de tales modelos de aparatos presentan en diferentes sitios elementos de accionamiento tales como reguladores y conmutadores, que se tienen que poder accionar a través de aberturas del inserto, y/o elementos de indicación, que se tienen que poder leer a través del inserto, se necesita, entre el espacio hueco interno del cuerpo del soporte y la escotadura que aloja el inserto, una ventana de gran superficie, a través de la que pasen los elementos de accionamiento o que deje ver los elementos de indicación. Por tanto, una unión entre el inserto y el cuerpo de soporte está limitada necesariamente a una zona de borde del inserto. Convencionalmente, el inserto se fija en el cuerpo de soporte con ayuda de una cinta adhesiva de doble cara.
Debido a tensiones congeladas en partes de las paredes del cuerpo de soporte y la escasa superficie adhesiva disponible, con temperaturas elevadas se puede producir un desprendimiento del inserto del cuerpo de soporte.
Es objetivo de la presente invención indicar un panel, un aparato equipado con un panel de este tipo así como un método para la producción del panel, que sean sencillos y económicos y que garanticen una unión firme, permanente entre el inserto y el cuerpo de soporte.
El objetivo se resuelve mediante un panel con las características de la reivindicación 1, un aparato con las características de la reivindicación 3 o un método con las características de la reivindicación 5.
Por radiación con infrarrojos de una zona de unión prevista entre el inserto y el cuerpo de soporte se puede realizar una unión permanente entre ambos, particularmente por soldadura o por activación de una capa de un adhesivo termoactivable localizada entre el cuerpo de soporte y el inserto.
Se obtienen características y ventajas adicionales de la invención a partir de la siguiente descripción de ejemplos de realización con referencia a las figuras adjuntas. Se muestra:
En la Figura 1,
una vista en perspectiva de las piezas individuales de un
panel de acuerdo con la invención en una representación
despiezada;
En la Figura 2,
el método para la unión del inserto con el cuerpo de
soporte; y
En la Figura 3,
un corte por el panel de acuerdo con la invención.
En la representación despiezada de la Figura 1 se observa un cuerpo de soporte 1, que está fabricado a partir de un plástico, por ejemplo, ABS, por moldeo por inyección, un inserto 2 de una lámina de plástico fuerte, rígida, un adaptador 3 y un circuito de control 4. En un lado frontal del cuerpo de soporte 1 se forma una escotadura 5, que está adaptada en forma y profundidad al inserto 2, de tal forma que el mismo, cuando se monta en la escotadura 5, rellena la misma completamente y termina de manera enrasada en sus bordes con el cuerpo de soporte 1. En el fondo de la escotadura 5 se forma una ventana de gran superficie 6 hasta un espacio hueco interno del cuerpo de soporte 1, que se proporciona para, fijado por el adaptador 3, alojar el circuito de control 4. El adaptador 3 presenta para esto varios ganchos de retención 7, 8, de los cuales el gancho de retención 7 sirve para el anclaje del adaptador 3 en la cubierta del circuito de control 4 y los ganchos de retención 8 se proporcionan para encajar en muescas 9 en el borde de la ventana 6, que están presentes en varios conjuntos para posibilitar el montaje del adaptador 3 en el cuerpo de soporte 1 en una pluralidad de posiciones.
El inserto 2 consiste esencialmente en un material de plástico permeable a infrarrojos, que está provisto en su lado posterior orientado hacia el cuerpo de soporte 1 de una capa decorativa, por ejemplo, por serigrafía. Esta capa decorativa no tiene que ser necesariamente permeable a infrarrojos. El material del cuerpo de soporte 1, por el contrario, absorbe infrarrojos.
La Figura 2 ilustra el método para la unión de inserto 2 y cuerpo de soporte 1. Para esto se mueve una fuente de radiación infrarroja 11, por ejemplo, una bombilla que emite infrarrojos o un láser IR, a lo largo del lado anterior del panel, de tal forma que el rayo de la fuente de infrarrojos 11 describe en el panel un trayecto 12 alrededor de la ventana 6 (no visible en la figura). Ya que el material del inserto 2 es permeable a infrarrojos, el calor del rayo de infrarrojos se libera esencialmente a la altura de la capa decorativa y la superficie del cuerpo de soporte 1 que se pone en contacto con la misma y suelda las mismas entre sí, como se indica por un sombreado denso en la zona 13 del trayecto 12 en la Figura 2.
De forma apropiada, el inserto 2 y su capa decorativa se fabrican a partir de un material resistente frente a mayores temperaturas que el cuerpo de soporte 1, y la potencia de la fuente de infrarrojos está dimensionada de tal forma que el cuerpo de soporte 1 se funde superficialmente por el rayo de infrarrojos, sin embargo, no el inserto 2 ni la capa decorativa. De esta manera se garantiza un aspecto agradable del panel terminado.
Como consecuencia de una segunda configuración de la invención, el inserto 2 se provee en su lado posterior antes de la inclusión en la escotadura 5 del cuerpo de soporte 1 de una capa de un adhesivo termoactivable. Preferiblemente, la capa se aplica solamente en una zona de borde del inserto 2, de tal forma que no se cruza con la ventana 6. Por irradiación con la fuente de infrarrojos 11 se activa el adhesivo y genera una unión permanente entre el cuerpo de soporte 1 y el inserto 2 sobre toda su superficie de contacto. La Figura 3 muestra un corte esquemático a través de un panel producido de este modo, donde la capa de adhesivo (representada de forma exageradamente gruesa) se indica con 14.
La temperatura de activación del adhesivo se sitúa claramente por debajo de la temperatura de fusión del material del cuerpo de soporte 1 o del inserto 2, de tal manera que se puede evitar una fusión de uno o del otro durante la fijación del inserto 2. De esta manera se disminuye por un lado el requisito de energía del método frente al caso considerado anteriormente de la soldadura por infrarrojos, por otro lado, no existe riesgo de que la fijación provoque modificaciones visibles desde el exterior en el inserto 2, que alteren
su aspecto agradable y, por tanto, lo puedan inutilizar.
