GAS COOKING STOVE
Document Type and Number:
Japanese Patent JP2022033659
Kind Code:
A
Abstract:
To provide a gas cooking stove (1) capable of suppressing a flame overflow state without limiting the maximum fire power of a concentric burner (10).SOLUTION: A gas supply passage (40) supplying fuel gas is branched off to two connection passages (40p and 40c), and those are respectively connected to a master burner (10P) and a slave burner (10C). A gas flow rate of the fuel gas in the gas supply passage or a distribution ratio of the fuel gas to the master burner and the slave burner is controlled according to set fire power, and the distribution ratio to the slave burner can be increased as the set fire power increases. In this way, if the master burner is in a flame overflow state, by increasing the distribution ratio to the slave burner, the flame of the master burner is made small to prevent the flame overflow state. In addition, even if the flame of the master burner becomes small, the flame of the slave burner becomes large, so that the fire power of the concentric burner is not lowered as a whole, and the maximum fire power is not limited.SELECTED DRAWING: Figure 5
