Field of the Invention The present invention relates to an operation type gas that is disposed on a top plate covering a gas furnace body with a heat source disposed on a gas furnace body. Furnace, in particular, relates to a gas furnace in which a top plate is formed by a glass top plate comprising a glass plate and a metal plate frame surrounding the glass plate. [Prior Art 3] In the past, although there is a gas furnace using a metal plate top plate, it is known that an operation button for a heat source is disposed on the upper surface of the top plate or on the upper side of the top plate. (For example, refer to Patent Documents 1 and 2). Moreover, when the top plate of the gas furnace is formed by the glass top plate including the glass plate and the outer frame of the metal plate surrounding the glass plate, the recessed portion facing downward is formed on the edge portion of the inner periphery 15 of the outer frame, and In a state in which the glass plate is fitted into the depressed portion, the gap filler is filled in the gap between the peripheral edge of the glass plate and the peripheral wall portion of the depressed portion, and the outer frame is attached to the glass plate. In general, the upper operating gas furnace using the glass top plate has the operating button disposed on the glass plate. However, due to design reasons, the operation button is required to be disposed on the outer frame. In the frame part of the configuration operation, in order to relocate the installation space, it is necessary to widen the plate support (the table in the gas furnace in the Syrian gas furnace and the gas furnace body in the table gas furnace). The width between the outer peripheral edge portion and the inner peripheral edge portion. Here, since the outer frame is made of a metal plate and the rigidity is not so high, if the width of (12) is added to the 1290204, the part will become easy to bend and the top plate will be damaged. Commodity. [Patent Document 1] Japanese Laid-Open Patent Publication (KOKAI) Publication No. JP-A No. 6048008 (Patent Document 2). The present invention is directed to the above problems, and an object thereof is to provide an improved configuration. Operate the rigidity of the outer frame part of the button and prevent damage to the commodity: Make a gas stove. In order to solve the above problems, the present invention relates to an upper operating gas furnace which is disposed on a top plate covering a gas furnace body with a heat source disposed in a gas furnace body, and The top plate is composed of a glass top plate including a glass plate and a metal plate outer frame surrounding the glass plate, and is arranged on the outer frame, wherein the outer frame is attached to the periphery of the glass plate. The upper portion of the outer frame is followed by the glass plate under the outer frame, and an extension extending to the outer frame portion of the operation button is formed on the glass plate. According to the present invention, the rigidity of the outer frame portion of the arranging operation can be increased by the extension of the glass plate extending to the lower portion of the portion, thereby preventing the top plate from being unsound and improving the commerciality. In the present invention, it is preferable that the extending portion of the glass plate is formed with a through hole through which the operation shaft of the operation sister is inserted, and the frame portion of the operation button is formed to have a convex forming portion fitted to the through hole. When the glass top plate is assembled, the glass plate and the outer frame can be positioned by fitting the convex molding portion to the through hole, so that the mounting jig can be used correctly without using a mounting jig or the like. In the state of positioning, the outer frame is attached to the glass plate, and the assembly of the glass top plate is improved. 5 At this time, it is preferable to have a cylindrical gasket inserted through the through hole, and the lining includes: a lower flange portion is disposed below the glass plate; and an upper flange portion is disposed above the outer frame And extending the tubular portion, extending above the upward flange portion, by which the glass plate can be entangled with the outer frame, and the immersion material can be prevented from seeping into the gas through the gap between the glass plate and the outer frame. In the furnace body, at the same time, by extending the clear part, the boiled material is prevented from infiltrating into the through hole. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view showing a gas burner according to an embodiment of the present invention. Fig. 2 is an enlarged cross-sectional view taken along line n_iu^ of Fig. 1. Fig. 3 is an enlarged cross-sectional view taken along line m-m of Fig. 1. 15 [Implementation of Cold Type] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Fig. 1 shows an embedded gas raft (refer to Figs. 2 and 3) installed in a kitchen of a system having a box on which an open surface is formed. Shaped gas furnace body 1. As shown in the second and third figures, the outer curved flange 1a is formed on the upper edge of the gas furnace body 1, and the gas furnace body 1 is placed in the gas furnace DCD opened on the countertop CT. The outer curved flange la is locked to the opening edge of the gas furnace opening CTa, and the gas furnace body 1 is suspended on the mesa CT. Further, the top plate 2 placed on the table top CT covers the upper surface of the gas burner body 1 from above with the outer curved flange la. 1290204 The top plate 2 is composed of a glass top plate, and the glass top plate comprises: a glass plate 3 formed by tempered glass or the like; and an outer frame 4 surrounding the glass plate 3 and being formed by pressure forming stainless steel Wait for the metal plate maker. The outer frame * is attached to the lower surface of the outer frame 4 in a state of being superposed on the peripheral portion of the glass plate 3, and is joined to the periphery of the glass plate 3 by the polyoxygen-based interstitial material 5. Further, a sealing member 6 is attached to the lower surface of the outer peripheral portion of the outer frame 4, and the top plate 2 is placed on the mesa CT through the sealing member 6 outside the outer curved flange 1a of the gas furnace body. As shown in Fig. 3, the rear portion 41 of the outer frame 4 projects upward, and the lower wall portion 42 of the rear edge of the rear portion 41 is provided with a vent opening 43, and the combustion 10 is supplied through the air vent 43 To the gas furnace body 1. A pair of right and left burner openings are formed in the glass plate 3, and the burner openings face the pair of right and left burners 7, 7 which are disposed in the gas burner body and serve as a heat source. Further, on the glass plate 3, a soup tray 8 projecting toward each of the burner openings is placed, and a fire holder 9 is placed thereon, and 15 burners for each burner are placed. Further, a pair of right and left operation knobs 1A and 1B for the pair of right and left burners 7 and 7 are disposed on the front side portion 44 of the outer frame 4. Further, as shown in Fig. 2, each of the operation buttons 10 is coupled to the operation shaft 12, and the operation shaft 12 extends upward from the valve unit 11 for each of the burners 7 provided in the gas burner body 1. Here, in order to ensure that the installation space of the operation buttons 1〇, 10 simultaneously achieves the balance of the setting 20, the front side portion 44 of the outer frame 4 widens the width in the front-rear direction, and at this time, the front side of the frame 4 is outside the front edge of the glass plate 3. When the vicinity of the inner periphery (the trailing edge) of the portion 44 serves as a terminal, the front portion 44 is easily deflected due to insufficient rigidity, and the top plate 2 has a feeling of being weak and impairs commerciality. Therefore, in the present embodiment, the glass sheet 3 is formed with an extension 31 extending forward to the lower side of the side portion 44 of the outer frame 1290204, whereby the front portion of the outer frame 4 can be supported by the extension portion 31 of the glass sheet 3. The portion 44 increases the rigidity of the front portion 44. Therefore, the top plate 2 can be prevented from having a feeling of being weak and improving the commerciality. The extension portion 31 of the glass sheet 3 forms a through-hole 5 for inserting the operation shaft 12, and the front portion 44 of the outer frame 4 is formed into a convex shape having a convex shaped portion 45a fitted to the through hole 32. The hole 45 allows the glass plate 3 and the outer frame 4 to be positioned by fitting the convex molding portion 45a to the through hole 32 when the glass top plate 2 is assembled, so that the mounting jig or the like can be used without using a mounting jig or the like. In the state of being correctly positioned, the outer frame 4 is followed by the glass plate 3, and the group 10 of the glass top plate 2 is lifted. Further, when the glass plate is embedded in the depressed portion formed on the inner peripheral edge portion of the outer frame as in the conventional glass top plate, the glass plate cannot be extended toward the front portion of the outer frame. Therefore, in the present embodiment, as described above, The outer frame 4 is attached to the glass plate 3 by a caulking material 15 5 under the outer frame 4 in a state of being superposed on the peripheral portion of the glass plate 3. Here, in the conventional glass top plate, since the interstitial material filled between the peripheral edge of the glass plate and the peripheral wall portion of the depressed portion appears in the appearance, therefore, the gap filler must be carefully and carefully filled in order to make the appearance good. The width and height of the caulking material can be made uniform throughout the entire circumference. In contrast, in the present embodiment, since the caulking material 5 does not appear in the appearance, the coating operation of the caulking material 5 becomes 20 It is easy, and this aspect can also improve the assembly of the glass top plate 2. Further, the top plate 2 is provided with a cylindrical lining 13 made of Shixia rubber special elastic material inserted through the through hole 32 of the glass plate 3, and the lining 13 includes a lower flange portion 13a which is disposed on the glass. The lower portion of the extension portion 31 of the plate 3; and the upper flange 1290204 portion 13b are disposed above the front portion 44 of the outer frame 4, and accordingly. The extension portion 31 of the glass sheet 3 is privately joined to the front portion of the outer frame 4 by the spacer 13, and the boiled material is prevented from penetrating into the gas furnace body 1 through the gap between the two portions 31, 44. The outline 13 further includes an extended tubular portion 13c extending upward from the upward flange portion i3b, whereby the elongated tubular portion 13c has a function as a bank portion surrounding the through hole 32, and also prevents the overflow of the boiled material. The hole 32 is dropped into the gas furnace body 1. Although the embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to the above embodiment. For example, the side portion of the lateral side of the outer frame 4 may be formed to have a wide width and be on the side. In some cases, the operation is described. At this time, the glass plate 3 is formed with an extension extending to the lower side of the side portion of the outer frame 4. Further, the present invention is not limited to the embedded gas furnace of the above embodiment, and the present invention is also applicable to a table type gas furnace, and is also applicable to a gas furnace using an electromagnetic induction coil or a heater as a heat source. 15 [Simplified Drawings] Fig. 1 is a perspective view showing a gas burner according to an embodiment of the present invention.
