<P>PROBLEM TO BE SOLVED: To solve such a problem peculiar to a gas cooking stove device with a master/slave burner that when cooking is continued while a master burner is extinguished and only a slave burner is in combustion state, backfire is caused in the master burner in a process where the thermal power of the master burner is lowered, and when the supply of gas to the master burner is not completed entirely and a minute amount of gas supply to the master burner is continued, combustion is undesirably continued in the burner body of the master burner. <P>SOLUTION: A range from a predetermined small-fire state causing backfire in a master burner to an extinguishing state is set as a backfire region for the master burner, with respect to a thermal power of a master burner, and a stoppage prohibition mechanism is provided so that a power adjusting knob 11 may be not stopped within the backfire region, thereby preventing the backfire. <P>COPYRIGHT: (C)2012,JPO&INPIT |
