Wherein, when the distance between the panel and the burner body in the upper and lower directions is relatively large, the inner peripheral portion of the guiding member may be erected toward the opening of the stove, and the inner peripheral portion may have a flame guide for introducing the flame of the burner into the opening of the furnace. Function (譬15, see, for example, Patent Document 1). Further, recently, glass top plate stoves made of glass have been commercially available because of their good appearance and cleanability. Patent Document 1 Japanese Patent Publication No. 7-40882 (page 2, first drawing). 20 Patent Document 2 The official fair 7-42002 (page 2, 2). When an internal flame type burner is used in a glass top plate furnace, since the temperature at the peripheral portion of the opening of the oven becomes quite high (300 degrees Celsius or more), it is necessary to form a panel with crystallized glass having excellent heat resistance. Such a crystallized glass panel 1263015 is weaker than tempered glass, and when the excessive load acts on the flame frame on the panel, the panel may be broken. In particular, when the hood disposed above the stove is maintained or cleaned, since the human foot is placed on the fire frame to exert an increased load on the fire frame, countermeasures for preventing the panel from being broken are desired. In addition, when the panel is made of tempered glass, it is necessary to prevent cracking when the thickness is reduced to reduce the weight. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide a glass top 10 plate stove which can be prevented from being broken by a guide member attached to an inner flame type burner. In order to solve the above problems, the glass top plate stove of the present invention is provided with a burner as a heat source in the main body of the stove, and a furnace opening facing the burner is opened on the glass panel covering the upper surface of the stove body, and is mounted on the panel. The firearm is arranged to surround the opening of the oven, and the burner is composed of an internal flame type burner, and the inner flame type burner is formed on the burner body concentric with the opening of the furnace. An inwardly facing flame hole, and an annular guiding member is mounted on the burner body, and a secondary air passage is defined between the guiding member and the upper surface of the burner body, the first feature of which is: An insertion portion into which the inside of the oven opening 20 is inserted is formed in the inner peripheral portion or the outer peripheral portion of the guiding member, and a seat portion that can abut the insertion portion from above is formed on the fire holder, and the fire frame is It is supported by the panel floating state. Further, according to a second aspect of the present invention, in the inner peripheral portion or the outer peripheral portion of the guide member, an insertion portion into which the opening of the oven is inserted is formed, and a gap is formed in the fire holder above the insertion portion. The opposing seat portion can be bent downward by the panel within the allowable range 1263015, and the fire frame is displaced downward. The seat portion abuts the insertion portion 0 in the first feature. The component supports the fire frame. Therefore, the load from the fire frame does not act on the panel. Further, in the second feature described above, the load from the flame frame acts on the panel, but when the panel is bent downward due to the load, the frame of the flame is broken after the amount of the bending exceeds the allowable range. The portion will abut the insertion portion, and then the guide frame can be used to support the fire frame. Therefore, both of the first and second features prevent excessive load from being applied to the panel through the flame frame, and the panel is not broken. In addition, in the glass-made panel, the fire frame positioning hole and the like cannot be formed. So far, the fire frame may be eccentric with respect to the burner, and the cooking device mounted on the fire frame may be heated unevenly. Here, if the tubular portion into which the insertion portion can be fitted is formed on the fire frame, it is advantageous to center the fire frame with the guide member as a reference. [Embodiment] Fig. 1 shows a immersed glass top plate stove having a panel (hereinafter referred to as a glass panel) 2 made of glass, for example, a crystallized glass superior in heat, on the upper surface of the main body 1. In the glass top plate 2, there are left and right ports 3, 3, and, in the stove body! Inside, the open surface S has a furnace opening 3, and each burner 4 is provided with 20 as a heat source. The pedestal 7 on the bottom plate of the furnace body 1 is flame-fired within the flame hole 6 in the annular shape concentric with the opening 3 of the oven. The W member 9, the guide member 9 and the burner 4, as shown in Fig. 2, have a plurality of orientations formed on the burner body 5. The combustion is fixed to the body 5 and disposed on the burner body 5 with an annular guide 1263015. The upper portion of the body 5 defines a secondary air for introducing air from the outside into the vicinity of the flame hole 6 as secondary air for combustion. Use the airway 8. The guide member 9 is attached to the burner body 5 via the bracket 10 at a plurality of positions in the circumferential direction. Further, the inner peripheral side portion of the guide member 9 is raised upward toward the oven opening 3, and a flame guiding member for introducing the flame of the burner 4 into the opening 3 of the cooker is formed on the inner peripheral side portion. Further, 'at the edge of the opening of the oven opening 3, a guard ring 11° for preventing cracking is installed, and below the inner diameter portion of the burner 4 (the space surrounded by the burner body 5) is an overflow of the receiving inner diameter portion. The boiled juice is set with a juice tray 10 trays 12. On the glass panel 2, a pair of left and right operation knobs 13 and 13 for the right and left burners 4 and 4 are disposed on the front side thereof, and a pair of left and right furnace openings 3 and 3 are disposed, and the left and right cooking containers p are disposed. A pair of fire frames 14, 14. Each of the fire holders 14 is composed of a plurality of fire holder claws 14a which are arranged at intervals in the circumferential direction, and an annular frame 14b which connects the fire holder claws 14a of the 15 and the like. In the present embodiment, the frame claw 14a and the frame frame 14b are integrally cast and formed of an iron-based material such as stainless steel. The fire frame 14b also covers the protective ring as a gap with the upper portion. Further, in the inner peripheral portion of the frame frame 14b, a seat portion 14c is formed which is formed by the upper portion of the guide member 9 which is inserted into the inner periphery of the opening member 3 of the upper opening 3, and is formed by the upper portion. The frame 14 can be supported by the guiding member 9 in a state of being floated by the glass panel 2. Therefore, even if an excessive load is applied to the flame frame 14, it is not excessively applied to the glass panel 2, and the glass panel 2 can be prevented from being broken. Further, 263 015 015 Further, under the frame frame 14b, a tubular portion Hd which is fitted to the upper edge portion of the insertion portion of the inner periphery of the guide member 9 is fitted. Therefore, the fire frame 14 is centered on the reference member 9 as a reference to prevent the relative fire of the burner 4 from being biased. 5 _ Figure 3 shows the implementation of Brother 2. This embodiment is slightly different from the basic configuration of the above-described first embodiment, and the same members as those described above are denoted by the same reference numerals as those described above. In the second embodiment, the flame frame 14 is placed on the glass panel 2 by a partition 14e screwed to the lower edge of the outer end portion of the frame claw 14a. Further, the seat portion Me of the inner circumference of the flame frame l4b is often disposed opposite to the upper edge portion of the inner periphery of the guide member 9 so as to leave the gap 1 therebetween. The gap L can be set to a downward amount in the allowable range of the glass panel 2, and can be set, for example, to 2 mm. According to this configuration, the load from the flame frame 14 acts on the glass panel 2, but when the glass panel 2 is bent downward due to the load, the seat portion is broken before the bending amount 15 exceeds the allowable opening of the glass panel 2. W will abut the insertion portion 9a. Then, the fire frame 14 is supported by the guiding member 9. Therefore, it is possible to prevent an excessive load from being applied to the glass panel 2 via the fire holder 14, and the glass panel 2 is not broken. In the above, the guide member 9 is described as using the inner peripheral side portion as the flame guiding member, but the distance between the slab panel 2 and the burner body $ is small in the vertical direction as shown in FIG. 4 In the embodiment, on the combustion body 5, the funnel-shaped guide structure 8 is inclined upward toward the outside, and the secondary air passage 8 is pulled out from the upper surface of the burner body 5. The guide member 15 is fixed to the burner body 5 at 20 1263015 by a bracket 16 at a plurality of positions in the circumferential direction. Further, the seat portion 14c on the inner circumference of the frame frame 14b abuts against the insertion portion 15a inserted into the outer periphery of the guide member 15 of the oven opening 3 to support the frame 14 in a state where the glass panel 2 is floated. In addition, as in the second embodiment, the fire frame 14 may be often placed on the glass panel 2, and the seat portion 14c may be disposed opposite to the insertion portion 15a on the outer circumference of the guide member 15 with a gap therebetween. The seat portion 14c abuts against the insertion portion 15a by being bent downward in the allowable range of the glass panel 2. Further, in the above embodiment, the stove is embedded, but the present invention is also applicable to the table top glass top cooker.
