Title:
BURNER FOR GAS COOKING APPLIANCE
Document Type and Number:
Japanese Patent JP3540200
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve flame stability of a weak flame of a burner.
SOLUTION: A deep burner port groove 6 and a shallow burner port groove 7 are formed on a ring-like burner port groove forming portion 5 of a burner head 1, and several flame stabilizing burner port grooves 10 are formed. The grooves 10 are wider in a groove width W than the groove 6, a length L of the groove is short, and the grooves 10 communicate with a distribution passage 4 by two inflows groove 12 partitioned by a partition wall 11. When the head 1 is placed on a burner body and burner ports are formed of the grooves and the body, high flame stability is brought about by a wide width W and a short length L of the burner port groove, and a resistance force against a back fire in a direction of an arrow (f) is generated by the wall 11.
