PROBLEM TO BE SOLVED: To provide a cooking stove burner capable of easily igniting by an ignition plug even with mixed gas in which a ratio of primary air is large, and having no possibility of igniting a cloth of a user.SOLUTION: A convex part is made to project on an outer peripheral side surface of a burner head on a side facing to an ignition plug, and mixed gas is made to flow out toward the ignition plug from an ignition burner port provided for the convex part. This makes the ignition burner port approach the ignition plug, and the mixed gas from the ignition burner port reaches the ignition plug before being attenuated. Because of this, even when mixed gas (lean mixed gas) in which a ratio of primary air is large is used, ignition can be securely carried out by spark discharge from the ignition plug. In addition, a flow rate of the mixed gas in ignition does not need to be increased, which does not generate possibility that ignition flame grows to ignite a cloth of a user. |
