The top plate 3 is composed of a metal frame 31 such as aluminum and a ceramic glass plate 32. In this embodiment, two circular openings facing the gas burner 4 described later are formed in the ceramic glass plate 32. -0 Below each opening of the top plate 3, a ring-shaped inner flame type gas burner 4 with a plurality of flame holes 4a facing the center is provided on the stove body 2 through the support member 22, and is provided below the inside of the gas burner 4. There are 5 overflowing sauce pans. An ignition button 6 of the gas burner 4 is provided on the top plate 3. A cylindrical 1228173-shaped guide member 8 and a thermocouple 9 are attached above the gas burner 4 provided in the stove body 2, and the guide member 8 is a base _ nailed to a woman's clothing in the gas burner 4 The support member 7 is supported, and the thermocouple 9 is used to detect the flame of the H4 gas burner. The guide member s is inclined in accordance with the direction of the flame from the flame hole 4af of the gas burner 4, and has a guide portion 8a that guides the flame 5 toward the center and tilts inward and upward. Further, the vicinity of the opening 3 & above the guide portion 8a is directed vertically upward, and the front end portion _ toward the opening σ edge portion _ of the top plate 3 is bent to form an enlarged portion, and the flame is guided toward the outside and above the opening 3a. In addition, since the flow path T is formed between the base portion 8c of the guide member 8 and the gas burner 4, the combustion air can flow in the direction of the arrow, and the fire of the gas burner * will not immediately rise and change. Effectively guide inward. The front end portion 8b of the V guide member 8 is located substantially on the same plane as the opening portion 3, and is located between the front end portion of the guide bow 8 and the opening edge portion of the top plate 3. There is also a gap G of several mm. In addition, the guide member 8 is fixed at its base to the screw: the support member 7 ′ 1 is because the support member 7 is mounted on the gas burner *, so the gas burner 4 and the guide member 8 are transmitted through the support member 7_ Incorporate, and hold the relevant position of both. A protection member 10 is fixed to the opening edge portion of the top plate 3 to protect the opening edge portion 3b. The fire frame 11 placed around the opening edge portion 3b of the top plate 3 is composed of six fire frames Ua and a fire frame frame lib connecting the fire frame claws 11a.
