Abstract

Una camara de deteccion de humos para utilizarse en un detector fotoelectrico de humos. La camara de deteccion de humos comprende una pared lateral con una doble fila de paletas generalmente rectangulares para proporcionar un laberinto que se extiende por lo general alrededor de toda la pared lateral para ingreso y salida de las particulas de humo, una superior y una inferior. El arreglo del montaje para un diodo emisor de luz se proporciona en la pared lateral de la camara de deteccion de humo de modo que un rayo de luz del diodo de emision de luz se transmite a traves de la camara de deteccion de humo. El arreglo de montaje se extiende desde y se separa desde el fondo para proporcionar la minima interferencia para la entrada de particulas de humo. El fondo de la camara de deteccion de humo tiene una abertura en la misma con un arreglo de blindaje en ella abierto a la camara de un detector de diodo emisor de luz, colocandose el arreglo de blindaje y la abertura entre la linea central de la camara de deteccion de humo y el arreglo del montaje en la pared lateral de la camara. La pared lateral de la paleta doble y el espacio del ajuste del montaje desde el fondo proporciona la camara de deteccion de humo con propiedades de penetracion de humo generalmente uniformes alrededor de su periferia total.
