<P>PROBLEM TO BE SOLVED: To provide a flame sensor which prevents malfunction and alerts reliably while sensing a flame caused in installation site surely, and which is small, lightweight and produced inexpensively because the structure of the flame sensor is simple, and suitable to be installed in an office or inside a car. <P>SOLUTION: A flame sensor comprises a sensor housing 1 which can be installed on a mounting surface 2. The sensor housing 1 is provided with ray introduction parts 13 to introduce ray contained in a flame into and a flame perception sensor sensing the ray. The flame sensor leads the ray to the flame perception sensor and can output an alarm through the perception of the flame. The inside of the sensor housing 1 is sectioned up and down by a partition board. A partition above the partition board is a flame detection room 11. The inner surface of the flame detection room 11 and the partition board can reflect light. The ray introduction parts 13 are provided on whole or plural points of the internal intermediate part of the flame detection room 11. The ray entered the ray introduction parts 13 can be introduced into the flame perception sensor through reflection of the inner surface of the flame detection room 11 or the partition board. <P>COPYRIGHT: (C)2012,JPO&INPIT |
