Infiltration can be suppressed, and the inside of the casing is not stained, so that careability, safety, and durability can be improved.

According to the second aspect of the present invention, the watertightness between the extension portion 2 and the top plate 5, which are formed in series with the burner 1, can be enhanced, and the inflow of broth or the like into the gas stove can be prevented. In addition, the heat resistance of the sealing material 9 can be lowered while increasing the commercial value, and a relatively low heat-resistant material can be used. In the configuration of claim 3, since the top plate 5 is made of glass, the appearance can be enhanced and the commercial value can be greatly increased as compared with a metal top plate, and further, the burner of the glass top plate 5 can be improved. Since the temperature rise in the vicinity of 1 can be suppressed, it is possible to prevent the top plate 5 from breaking due to heat, and it is not necessary to use expensive crystallized glass for the top plate 5 itself, and it is possible to use general tempered glass. Cost can be reduced.

According to the fourth aspect of the present invention, the burner main body receives heat from the flame of the burner 1 at the extension portion 2 slightly higher than the top plate 5 and closer to the burner 1 than the top plate 5. By conducting heat to 17, the temperature increase of the extension 2 and the top plate 5 can be suppressed, and the temperature in the circumferential direction of the top plate receiving portion 3 formed on the outer periphery of the annular extension 2 can be reduced. For example, the temperature of the peripheral portion of the opening 4 of the top plate 5 where the temperature difference is most likely to occur for mounting and supporting the top plate 5 made of glass can be substantially equal. There is no crack or crack in the top plate 5 made of steel.

According to the first aspect of the present invention, there is provided a gas stove in which a burner faces an opening of a top plate, and a series of burners is provided on an outer peripheral portion of a metal burner and is substantially flush with the top plate. Since the protruding portion is formed, the extension from the burner flame is received by the extension portion and is conducted to the burner main body by the extension portion formed on the burner in a series on the outer peripheral portion of the burner. Therefore, it is possible to suppress a rise in the temperature of the top plate near the burner. Therefore, when the top plate is made of a thin steel plate or an aluminum plate, thermal expansion and thermal insulation are not required, and the heat expansion and thermal insulation are not required. The advantage is that, even when the surface of a thin steel plate aluminum plate is treated with fluorine coating etc., the temperature rise of the top plate can be suppressed, and the durability of the coating layer can be improved. A. When the top plate is made of glass, it is possible to suppress a rise in temperature in the vicinity of the burner of the glass top plate, prevent the top plate from breaking due to heat, and add expensive crystallized glass to the top plate itself. You do not need to use
General tempered glass can be used, the cost can be reduced, boiled spills can be prevented from sticking to the top plate, and in addition, the temperature rise of the top plate can be suppressed, and the opening of the top plate can be suppressed. High heat resistance is not required for the sealing material that fills the gap between the part and the burner, making it possible to use relatively low heat resistant ones. There is an advantage that the infiltration into the casing can be suppressed, the inside of the casing is not stained, and the careability, safety and durability can be improved.

According to the second aspect of the present invention, since the sealing material is interposed between the outer peripheral portion of the extending portion and the opening of the top plate,
It is possible to increase the water tightness between the extension part and the top plate, which are in series with the burner, to prevent the inflow of broth etc. into the inside of the gas stove, to enhance the commercial value and to have the extension part Thereby, the heat-resistant temperature of the sealing material can be lowered, and a relatively low heat-resistant material can be used.

According to the third aspect of the present invention, since the top plate is made of glass, its appearance can be enhanced and its commercial value can be greatly increased as compared with a metal top plate. Since the temperature rise in the vicinity of the burner can be suppressed, the top plate is prevented from breaking due to heat, so that expensive crystallized glass does not need to be used for the top plate itself, and general tempered glass can be used, and cost can be reduced. There is an advantage that can be reduced.

According to the fourth aspect of the present invention, the extension portion is formed in an annular shape and is slightly higher than the top plate, and a top plate receiving portion is formed on an outer peripheral portion of the extension portion. Because the edge of the opening of the top plate is placed on the part, it is slightly higher than the top plate, and receives heat from the burner flame at the extension that is closer to the burner than the top plate By conducting heat to the burner main body, it is possible to suppress the temperature rise of the extension portion and the top plate, and it is possible to make the temperature in the circumferential direction of the top plate receiving portion formed on the outer periphery of the annular extension portion substantially equal. For example, when mounting and supporting a glass top plate, the temperature of the periphery of the opening of the top plate where the temperature difference occurs most can be made substantially equal, and the temperature difference causes a crack in the glass top plate, for example. There is an advantage that cracks and cracks can be avoided.
