Title: Stove
Inventor: MIYATO AKIRA
IPC: F24C3/12
Filed: 2019-03-14
Abstract: To provide a safe stove capable of preventing ignition at foreign matter even in a case of detecting the foreign matter in a process of ignition operation.SOLUTION: A CPU measures a distance from a top plate to foreign matter based on reflected light received by a light receiving unit of a sensor. The CPU determines whether there is a sensor indicating that the height of the foreign matter is less than or equal to a determination value during ignition operation of a stove burner (S15). When there is the sensor indicating that the height of the foreign matter is less than or equal to the determination value (S15: YES), in order to interrupt the ignition operation, the CPU forcibly stops driving the igniter (S16), and closes a gas flow passage to stop the gas supply to the stove burner (S17, S18). Consequently, since the stove burner is prevented from burning, it is possible to prevent ignition at the foreign matter and improve safety.SELECTED DRAWING: Figure 6
