【従来の技術】[Prior art]

ガステーブル等に用いられるこんろバーナは、環状混合室を有するバーナ本体 上に多数の炎口溝を放射状に備えたバーナヘッドを脱着自由に載置して周縁に多 数の主炎口を配設する構造となっていて、主炎の下部に袖火を形成して高負荷と することによりその絞り性能を向上させ、たとえば、とろ火操作時の不具合、急 激な操作による吹き消え等を解消し、併せて、点火時の火移り性能の向上、リフ ト防止等をも図っている。 A stove burner used for a gas table or the like is equipped with a burner head having a large number of flame openings in a radial manner on a burner body having an annular mixing chamber, and is provided with a plurality of main flame openings on a peripheral edge. A high-load is formed by forming a sleeve flame below the main flame to improve the throttle performance, and for example, to eliminate malfunctions during throat operation and blow-out due to sudden operation. At the same time, it also improves the fire transfer performance during ignition and prevents lift.

【0003】 そこで、従来のこんろバーナにおいて、バーナ本体とバーナヘッドとの接合部 に主炎とは独立した袖火を形成する袖火炎口を設けたものはすでに知られている (たとえば、実開昭58−71520号公報参照)。[0003] In view of the above, a conventional stove burner in which a sleeve flame opening for forming a sleeve flame independent of a main flame is provided at a joint between a burner main body and a burner head is already known (for example, an actual burner). See JP-A-58-71520).
