Title: Thermocouple device
Inventor: KODERA HIROSHI
IPC: F23N5/10
Filed: 1985-10-25
Abstract: PURPOSE:To detect a temperature drop of a hot juncture with high sensitivity, by arranging conductors, from first to fourth, in series, forming a thermocouple having a hot juncture consisting of a juncture of the second conductor with the third one, causing thus thermoelectromotive force between the first and the second conductor and that between the third and the fourth to be polarized in the reverse direction of that between the second and the third conductor. CONSTITUTION:A juncture of a conductor 22b with a conductor 22c which forms a hot juncture 22e is disposed in an auxiliary chamber 13 to be heated with the flame of gas supplied from a gas passage 14, while lead wires 25 are connected to a conductor 22a and 22d. For the first conductor 22a and the third conductor 22c, material of the same sort, e.g., chromel is used and for the second conductor 22b and the fourth conductor 22d another material of the same sort, e.g., alumel is employed. Therefore, in an ordinary combustion, thermoelectromotive force E takes a relatively large positive value, so that an electromagnetic valve of a safety device is sufficiently excited, causing said valve to be maintained at an open state. At an abnormal stop of combustion, thermoelectromotive force E becomes less than zero, i.e., negative. That means that said force always has a state of zero before coming to negative, whereby the safety device can be rapidly and surely actuated.
