Abstract

Dispositivo de bloquea del portilla de una máquina lavadora, el cual comprende: una carcasa de soporte (1 a 3); un elemento resistivo calefactor (12), de tipo PTC, sostenido en la carcasa (1 a 3) y que está destinado a ser sometido a una tensión eléctrica y a calentarse cuando se activa la máquina: elemento bimetálico actuador (14), puesto en contacto con una cara del elemento calefactor (12) de tal modo que cuando ese elemento (12) se calienta su temperatura y la de dicho elemento bimetálico (14) presentan un período inicial (t 1 - t 0 de crecimiento rápido, seguido de un período ((t > t 1) de crecimiento más lento; dicho elemento bimetálico (14) es capaz de deformarse, a causa de su calentamiento, para causar el desplazamiento de un órgano de bloqueo (18) apto para impedir la abertura del portillo; y a l o menos un elemento bimetálico de control (10a, 10b, 10c), que está unido eléctricamente con la otra cara del elemento calefactor (12) mediante un elemento conductor intermedio (11) y quees capaz de asumir, por efecto de su calentamiento, una deformación de efecto contrario a la del elemento bimetálico actuador (14), caracterizado en que dicho elemento conductor intermedio (11) es virtualmente indeformable en el campo de temperaturas de trabajo del dicho elemento calefactor (12) y presenta tal forma y tal capacidad térmica que hacen que dicho elemento bimetálico de control (10a, 10b, 10c) se caliente, por efecto del calentamiento de dicho elemento calefactor (12), con un retardo preestablecido respecto al elemento bimetálico actuador (14) y con una dinámica (C) sucesiva que corresponde virtualmente a la dinámica de crecimiento lento (A'') de la temperatura de dicho bimetal actuador (14), el cual retardo es virtualmente de la misma magnitud que dicho período inicial (t 1 - t 0) de crecimiento rápido de la temperatura de dicho elemento resistivo calefactor (12).
