Title: Safety device for preventing oxygen starvation in stove
Inventor: MATSUDA YUKIKAZU
IPC: F23N5/24
Filed: 1981-12-01
Abstract: PURPOSE:To indicate that a safety device for preventing oxygen starvation in a sotve is actuated by an arrangement wherein an oxygen starvation sensor is connected with an indicator means adapted to indicate that the sensor is being actuated. CONSTITUTION:An electric current flows through a resistor 48 and an LED49 so that LED49 is lighted to indicate that an oxygen starvation sensor 14 is actuated. If the sensor 14 is actuated properly and when a point (f') becomes higher, electric current flows through a resistor 32, a point (g) and a resistor 33 thereby charging a condenser 36. When a point K raises slowly and exceeds a potential determined by a Zener diode 50, a transistor 35 turns ON. As a result an IC for timer is momentarily reset because the collector of the transistor 35 is connected with a point (d). Further, a point (e) becomes higher and in turn the point (f) becomes higher to turn a transistor 47 OFF so that LED49 turns OFF. Thus, it can be confirmed by turn-ON and -OFF of LED49 that the oxygen starvation detector circuit is functioning properly.
