JPS55118510A - Burner mechanism having multiflame port - Google Patents

Abstract

PURPOSE: To prevent uneven heating in a pan or a pot and to prevent uneven cooking or grilling by a method wherein a burner of a handy gas range is made to be a multi-stage flame port type.

CONSTITUTION: When fuel gas is supplied to the mixing pipe 1 by a gas supply pipe, a volume of air is introduced from the air ports 4, 4 in response to a volume of gas. The gas and the air are sufficiently agitated, mixed and lifted, a portion of the mixed gas and air is introduced from the inlet port 16 into the expansion chamber 17. The mixed fluid flowed in the expansion chamber 17 is injected from the burner flame port 14 and sufficiently mixed with the air flowed from the secondary air pipe 11. Other mixing fluid is filled in the burner main body 6, injected from the burner flame port 9 and the surrounding air is taken into the burner as a combustion air. In this way the combustion is performed under two steps, so that a high volume of heating calory is made, a bottom of the pan or the pot is uniformly heated resulting in uniform cooking and a cooking time is substantially shortened.
