STOVE BURNER

PROBLEM TO BE SOLVED: To prevent failure resulting from accumulation of dirt in an air-fuel mixture supply flow passage, in a stove burner where a mixer tube is continuously provided on a lower surface of a burner head.SOLUTION: A stove burner 1 includes: a hollow burner head 11 having a plurality of flame holes 23; a mixer pipe 12 continuously provided to a lower surface 111 of the burner head 11, and configured to mix air and fuel gas supplied from a gas supply part P1 to guide them to an internal space 20 of the burner head 11; and a flame detection sensor 31 provided proximately and oppositely to a specific flame hole 24, and configured to detect presence/absence of combustion flame outside the specific flame hole 24. On an inside bottom surface 11B of the burner head 11, an inner cylindrical part 13 whose upper end is opened and which has a height higher than a lower end of the specific flame hole 24 is continuously erected from the mixer pipe 12.SELECTED DRAWING: Figure 3 【課題】バーナヘッドの下面に混合管が連設されたコンロバーナにおいて、混合気供給流路の汚れの蓄積に起因する不具合を防止すること。【解決手段】複数の炎孔２３を有する中空のバーナヘッド１１と、バーナヘッド１１の下面１１１に連設され、ガス供給部Ｐ１から供給される燃料ガスを空気と混合してバーナヘッド１１の内部空間２０へ導く混合管１２と、特定の炎孔２４に近接対向して設けられ、特定の炎孔２４の外側における燃焼炎の有無を検知する炎検知センサ３１とを備えたコンロバーナ１であって、バーナヘッド１１の内側底面１１Ｂに、上端が開口し且つ特定の炎孔２４の下端高さ以上の高さを有する内筒部１３が混合管１２から連続して立設されたこと。【選択図】図３
