PURPOSE:To secure stable burning regardless of the cooling and high temp. time of a burner main body and prevent lighting-back at the re-ignition time by a method wherein a heat movable restriction rod is placed in front of a nozzle and is forcibly moved to front of the nozzle at the ignition time. CONSTITUTION:When a burner main body 1 is ignited, gas spouted from a gas nozzle 6 collides with a restriction rod 10 to reduce primary air supply from an opening part 7 induced by a gas spouting force and form flames stable at the burning flames holes 3 of a burner cap 2. When the main body 1 is warmed up, a heat movable element 14 is deformed to move the rod 10 in the front outward direction of the nozzle 6 and then ejector action is strengthened because the spouting force from the nozzle 6 is not hindered and the primary air supply from the part 7 is increased to continue stable burning. When re-ignition is carried out at the high temp. time of the main body 1, the lever 13 of an appliance plug 12 enables the element 14 to move forcibly the rod 10 in front of the nozzle 6 and lighting-back etc. at the ignition time can be prevented. |
