Abstract

Dispositivo de control para almohadillas, mantas eléctricas y similares. Comprende un hilo calefactor (1), un fusible (2), y medios de control (3) de la temperatura de dicho hilo calefactor, y se caracteriza porque el hilo calefactor (1) presenta un ánima conductora (4); una capa aislante (5) de temperatura de fusión controlada; un devanado de hilo conductor (6) dispuesto alrededor de dicha capa aislante (5); y una capa aislante exterior. Una segunda realización comprende un segundo hilo con una capa aislante de coeficiente de temperatura negativo, cuyo hilo está conectado en serie con el hilo calefactor con un capa de aislante de temperatura de fusión controlada. En una tercera realización, el hilo calefactor comprende un segundo devanado de hilo conductor con una capa de aislante de coeficiente de temperatura negativo dispuesto dentro de la capa de aislante exterior. Se mejoran las condiciones de seguridad.Control device for pads, electric blankets and the like. It comprises a heating wire (1), a fuse (2), and means for controlling (3) the temperature of said heating wire, and is characterized in that the heating wire (1) has a conductive bore (4); an insulating layer (5) of controlled melting temperature; a winding of conductive wire (6) disposed around said insulating layer (5); and an outer insulating layer. A second embodiment comprises a second wire with an insulating layer of negative temperature coefficient, the wire of which is connected in series with the heating wire with an insulating layer of controlled melting temperature. In a third embodiment, the heating wire comprises a second winding of conductive wire with an insulating layer of negative temperature coefficient disposed within the outer insulating layer. Safety conditions are improved.
