Abstract

PURPOSE:To prevent the occurrence of explosive ignition, by a method wherein a shut-off valve, which is opened and closed by means of heat produced by combustion of a combustion cylinder, is mounted to a bypass circuit, during ignition, the shut-off valve is closed, a gas amount is controlled, and the shut-off valve is opened as combustion rises, and a gas amount is increased to a maximum value. CONSTITUTION:A shut-off valve 9, placed in a bypass circuit 8, is located so that it is opened through a rod 11 through thermal deformation of a bimetal 10. During ignition, the bimetal 10 is not deformed, the shut-off valve 9, located in the bypass circuit 8 within a gas valve 6, is closed, and a gas amount is controlled. As combustion rises, the shut-off valve 9 is opened through a rod 11 through deformation of the bimetal 10 to bring a gas amount to a maximum value. Namely, since, during ignition, combustion cylinders 1 and 2 are not heated to suficient redness, a vent force is decreased, and as a result, an amount of a secondary air, fed through openings 13 and 14 by means of the vent force, is low. If a gas amount is brought to a maximum value, combustion gas becomes surplus, and this prevents flame from becoming unstable.

すい欠点があった。Conventional structure and its problems In conventional all-secondary air type gas burners, for example, the instability of the flame at the time of ignition is resolved because the air required for combustion is supplied by the ventilation force of combustion, so the amount of gas at the time of ignition is stabilized. It's hard to avoid. Particularly in the case of combustion gas that is heavier than air, there is a drawback that explosive ignition is likely to occur due to accumulation of combustion gas at the bottom of the appliance when ignited.

火炎が不安定なることを防ぐ。Combustion gas 12 supplied from the gas valve 6 passes through the gas valve 6, reaches the burner head 5, is ejected into the atmosphere from the combustion gas nozzle 4, and is blown into the inner lower opening 13 of the combustion cylinder 2, the combustion cylinder 1, and the cylinder. It mixes with secondary air supplied from the opening 14 between the cylinders 1 and 2, forms a flame in the pores 15 of the combustion cylinders 1 and 2, and burns. Bimetal 1 during ignition
0 is not deformed, the shutoff valve 9 installed in the bypass circuit 8 in the gas valve 6 is closed, and the amount of gas is limited.
