BURNER FLAME HOLE STRUCTURE OF GAS COOKER

摘要

PURPOSE: A burner flame hole structure of a gas cooker is provided to prevent backfires by generating gas flow resistance in the opposite direction the discharge direction of gas while minimizing the gas flow resistance in the discharge direction of gas. CONSTITUTION: A flame hole structure comprises a gas discharge passage(H') having an inlet(A) and an outlet(B) and a stepped portion(T) is formed in the lateral section of the gas discharge passage to resist the opposite flow of gas. Furthermore, the stepped portion is vertically formed in the gas discharge passage. The diameter of the passage gets narrow from the inlet to the stepped portion and narrower from the stepped portion to the outlet. Herein, the gas discharge passage consists of a passage groove(91) formed in a burner cap(90) and a burner head(10) on which the burner cap is placed.
