According to a first aspect of the present invention, there is provided a gas stove having a burner in which a plurality of flame ports are radially arranged on an outer periphery of a gas stove. A plurality of stakes for placing a cooking pot provided to be located on the stake ring are placed on the top plate, and a gap is provided between the stake ring and the top plate. In the gas stove that is formed and takes in the secondary air for combustion of the burner from at least the gap, the stake ring has an inclined flange portion extending by inclining the inner peripheral surface downward toward the ring center. Prepared,
The tip of the inclined flange is formed so that the horizontal distance from the outer peripheral surface of the flame port is within 30 mm and lower than the lowermost end of the flame port, and guides the secondary air to the vicinity of the flame port. That is the gist.

A gas stove according to a second aspect of the present invention is the gas stove according to the first aspect, wherein a gas ejection direction from the flame opening and an inclined surface of the inclined flange portion are viewed from the side. The gist is that the inclined flanges are formed so as to be parallel or at an angle of 20 degrees or less with each other.

[0007] According to the gas stove according to the first aspect of the present invention having the above structure, the tip of the slanted flange of the virtue is made to approach the outer peripheral surface of the burner port of the burner. It is guided from below the gotoku ring to the vicinity of the flame outlet and supplied from the base to the end of the flame to improve the combustion performance. Therefore, even if the mounting surface of the cooking pot is brought closer to the burner to improve the heating efficiency of the cooking pot, the combustion performance can be maintained satisfactorily.

Further, according to the gas stove according to the second aspect of the present invention, since the slanted flange of the virtue is parallel or almost parallel to the direction of gas ejection from the flame opening, the flame is formed by the slanted flange. It is possible to prevent the combustion performance from deteriorating without being hindered. Since the inclined flange is heated while maintaining good combustion performance in this manner, the secondary air is warmed when passing below the inclined flange. As a result, the decrease in the temperature of the flame is reduced, and the efficiency of heating the cooking pot can be improved.
