玻璃面板10包含有耐熱性玻璃板（陶瓷玻璃)2、圍繞其 外周緣部之保護體3、及開設於玻璃板2左右之各位置且安 裝於燃燒器開口 2a之開口周緣之保護環20。又，收容於爐 15本體52内之瓦斯燃燒器54面臨燃燒器開口 2a，且火架55載 置在玻璃板2之保護環20外側。在第4圖中，符號56係檢出 燃燒器54點火停止之熱電偶，且59係覆蓋火焰引導構件58 與保護環20間隙之湯汁蓋。 保護體3雖係支撐玻璃板2外周緣部之支撐框，但同時 20也是保護玻璃板2外周緣部之構件。因而在本發明中，該保 護體3意味包含插設於玻璃板2外周緣部與支撐框之間之緩 衝材。在本實施形態中，將保護體3組裝形成前後兩支長的 框材4、5與左右兩支短的框材6、7之矩形狀，且在框材4、 5、6、7之間設有玻璃板2之設置領域，以支撐玻璃板2外周 8 200424484

樣的構。该等所框材4、左右框材6、7及後部片8之長向 兩端端面係朝内方變窄且以45度之角度傾斜。後框材5則形 成/、有由垂直壁5a下端向前方水平突出之緣部％之截面構 這後框材5之長向兩端之緣部外係朝内側變窄且以45度之 角度傾斜。 後部片8與右框材7係由歛合設置於後部片8之緣部訃 端部之逆二角形之頭部8Μ與設置於框材7之緣部7b端部之 15二角形狀凹部7bl而結合。後部片8與左框材ό，前框材4與 左框材6，前框材4與右框材7也同樣地結合，並將該等四支 框材4、6、7，後部片8裝配成框狀。又後框材5與左框材6 係由歛合設於後框材5之緣部5b之逆三角形狀頭部5Μ與設 置於左框材6之緣部6b途t之三角形狀凹部6M而結合。後 20框材5與右框材7也可同樣地結合。 玻璃板2之支撐部係以矩形狀支撐框邊所構成，且該支 撐框邊係由前後框材4、5，左右框材6、7之水平緣部4b、 5b、6b、7b形成，並且玻璃板2載置在該支撐部上面。在所 載置之玻璃板2與該等框材4、5、6、7之垂直壁4a、5a、6a、 9 200424484 7a之間，可填充作為緩衝材之魏縫材$，使玻璃板2不會 偏離保護體3，以牢固保持並且確保水密性。 保護環2〇係由上環η與下環a構成，且該上下環η、 22包含有可插入燃燒器開口 2a内之筒部〕^、2訃與對向於 5玻璃板2^^ 口周緣上面與開口周緣下面之上下凸緣部⑴、 22a。在本例中，下環22之筒部22b以一定間隙插入燃燒器 開口 2a，且上環21之筒部21b嵌合下環22之筒部22b内周。 該間隙具有即使保護環熱膨脹，也不會對玻璃板2之燃燒器 開口 2a内周面施力之尺寸。 10 該上下環21、22之筒部21b、22b具有兩者在上下方向 大略全長地嵌合之長度，且在其中一者，譬如於上環21之 筒部21b上，於周方向複數處形成有卡合孔21c，並且在下 環22之筒部22b上，於朝直徑方向内方突出之周方向複數處 形成有突起22c。而且，各突起22c卡合在各卡合孔21c上， 15 使上下環21、22不會分離，以結合兩筒部21與22。藉將如 此的保護環20安裝於玻璃板2之燃燒器開口 2a開口周緣，可 保護開口周緣。此外，雖突起22c係以切起爪形成，但也可 作成壓花狀突起。 再者，在上凸緣部21a與玻璃板2之間插設襯墊23，以 20 襯墊23阻止從烹調器溢出來的煮汁由上環21與玻璃板2之 間之間隙通過燃燒器開口 2a繞進玻璃板2下面’可確實地防 止溢出來的煮汁朝爐本體2内落下。又，在下凸緣部22a與 玻璃板2之間，插設有用以保護玻璃板2襯墊24。 於本實施形態中，在下凸緣部22a設有環狀凹部22d， 10 且插設玻璃板2下側之襯墊24下部收容保持於該凹部22d。 在該下凸緣部22a之環狀EJ部22d外周部全周，將對向於玻 璃板2與狹窄間隙之水平部22f接續設置於凹部22d上端。 插設於玻璃板2下側之襯墊24由於藉結合上下環21、22 壓接玻璃板2，故藉由保護環20之旋動會由下凸緣部22&產 生滑動力，且襯墊24可輕易地由下凸緣部22a朝直徑方向分 離而脫落。如上述，下凸緣部22a設有環狀凹部22d，若將 襯墊24保持在該凹部22d，則由於能限制襯墊24直徑方向之 移動，故可防止襯墊24由上凸緣部22a偏離直徑方向脫落。 又，只要設有凹部22d，襯墊24就能輕易定位，且使在安裝 保護環20之際的組裝變得簡單。又，只要在凹部22d外周部 設置水平部22f與玻璃板2對向，即使下凸緣部22抵接玻璃 板2下面，也難以損傷玻璃板2下面。 然而，若保護環20旋動，則上凸緣部2ia之外周垂下部 2Id磨彳祭玻璃板2之燃燒器開口周緣表面，有下環22之筒部 22b磨擦玻璃板2之燃燒器開口内周面之虞，且有損傷該等 面之危險性。 所以，在本發明中，在下凸緣部22a設置延長部22e作 為防止保護環20旋動之裝置。該延長部22以系以與下凸緣部 22a直徑略同一尺寸之寬度從下凸緣部22a之水平部22f單向 地水平延伸，且具有到達並接觸玻璃板2之保護體3之一處 的長度。在本實施形態中，延長部22e係伸長至與保護體3 之左右框材6、7平行玻璃板2後方，到達並接觸由保護體3 之後框材5之垂直壁5a下端向前方水平延伸之緣部5b前端。 200424484 理想的是，在延長部22e寬度方向兩側部設置朝下方之 彎曲片22el。如此，由於不僅可以只利用延長部22el之板 厚而與緣部5b前端之接觸，亦可藉由彎曲片22el在高度方 向上得到接觸，故可輕易接觸緣部5b前端，且可確實與緣 5 部5b之前端接觸。又，藉由彎曲片22el提高延長部22e剛 性，可防止延長部22e變形。雖彎曲片22el越長該剛性越 佳，但圖示之W並非〇，亦即至少筒部22b與彎曲片22el只 要在一部份重疊即可。 根據本實施形態，若因人清掃玻璃面板10等而接觸磨 10 擦保護環20，則下凸緣部22a之延長部22e與後部框材5之緣 部5b之接觸部將成為保護環20之旋動阻力，使保護環2〇不 會旋動。因而，並不會產生因保護環擦傷玻璃板2之燃燒器 開口 2a開口周緣表面或開口内周面，或因保護環2〇磨擦損 耗插設於玻璃板2與保護20之間之襯墊23或24,結果使襯墊 15 脫洛寺缺點。又’由於將槪塾24保持在設置於下凸緣部22a 之環狀凹部22d，以限制襯墊24朝直徑方向之移動，故可防

Invention 3 The present invention relates to a gas furnace that covers the upper surface of the furnace body with a glass panel that surrounds the outer peripheral portion of the glass plate with a protective body. Improved protection ring installed around the opening edge of the glass panel burner opening. L It is well known for gas stoves that cover the glass panel above the furnace body with a glass panel that protects the outer peripheral part of the glass plate with a protective body such as a frame, and the burner opening opened in the 10 panel glass plate is useful to protect the Protective ring on the open perimeter. Conventionally, the protection ring includes a cylindrical part that can be inserted into the burner opening, and upper and lower flange parts facing the upper edge of the opening of the glass plate and the lower edge of the opening edge, so that the upper and lower flange parts can be connected through the cylindrical part (for example, see Patent Document 15 (2). By mounting such a protective ring on the opening periphery of the burner opening, the opening periphery can be protected. In order to prevent the overflowing boiling juice from falling into the furnace body or protecting the glass plate, a gasket is inserted between the upper flange portion and the glass plate, or a gasket is inserted between the lower flange portion and the glass plate. 20 [Patent Document 1] Japanese Patent Application Laid-Open No. 10-318545 However, in the above-mentioned conventional glass panel, since the protective ring is round, the protective ring may rotate when cleaning the panel or the like, and may damage the surface of the burner opening peripheral edge of the glass plate or On the inner peripheral surface of the opening, and a liner 5 200424484 插 k is inserted between the protective ring and the glass plate, there will be a small pad of the rotation loss of the protective ring, resulting in the disadvantage of falling off. [Summary of the Invention] ^ The problem of the present invention is to provide a gas furnace that does not cause damage to the plate during cleaning, etc., or that the lining overturns or falls off depending on the situation 5. In order to achieve the above object, the present invention is a gas furnace, which is composed of a furnace body capable of accommodating a gas burner and a panel covering an opening on the upper surface of the furnace body. A protective body and a 10-protection structure for protecting the periphery of the opening of the burner opening provided in the glassy soil plate, and the protective ring includes a tube portion that can be inserted into the burner opening, and a glass plate facing the glass plate. The upper edge of the opening and the lower edge of the opening α are connected to the upper flange portion by the rhyme portion, and an extension is formed in the lower flange portion to reach and contact one of the protection bodies to prevent the protection ring from rotating. According to the present invention, even if the position of the extension portion is deviated from above the protector, since the extension portion of the lower flange portion can be easily contacted with the protector, a downwardly-shaped help piece can be formed on the extension 4. In addition, since the overflowed boiling juice can be prevented from falling to the panel inside the furnace body, a liner can be inserted between the upper flange portion and the glass plate, and the lower flange portion can be connected with the glass in order to protect the broken plate. A pad is interposed between the filler plates 20. In the present invention, even if the user contacts the protective ring of the haze due to the cleaning of the glass panel, the contact portion between the extension of the lower flange portion and the protective body prevents the protective ring from rotating, so that the protective ring does not rotate. Therefore, the friction around the opening of the glass plate burner opening or the inner circumference of the burner opening due to the protection ring will not damage the protective ring friction when the gasket is inserted between the glass plate and the protection ring. As a result, the liner will not fall off. In another aspect of the present invention, the lower flange portion is provided with an extension portion that reaches and contacts one of the uranium furnace bodies to prevent the protection ring from rotating, and 5 is provided in the lower flange portion to reach and contact the foregoing flange portion. One of the protection bodies is an extension for preventing the protection ring from rotating. Another aspect of the present invention is a gas furnace composed of a furnace body capable of accommodating a gas burner and a panel covering the opening on the upper surface of the furnace body, and the panel is composed of a glass plate, a protective body surrounding an outer peripheral portion thereof, And a protection ring for protecting the opening periphery of the burner opening of the glass plate, and the protection ring includes a cylindrical part that can be inserted into the burner opening, and an upper surface facing the opening edge of the glass plate. The upper and lower flanges are connected to the lower edge of the opening and through the tube portion, and a gasket is inserted at least between the lower flange and the glass plate. Keep the ring-shaped recess of the previously inserted pad. Since the gasket under the inserted glass plate is crimped by the glass plate, the sliding force of the lower flange portion is generated by the rotation of the protective ring, which makes the gasket easily deviate from the lower flange portion in a straight direction. However, as long as the gasket is held in the annular recess provided in the lower flange portion, the movement in the diameter direction of the gasket can be restricted. Therefore, even if the protection ring is rotated, the gasket can be prevented from moving from the lower flange portion. Deviates from the diameter direction *. According to the present invention, at the upper end of the outer peripheral portion of the annular recessed portion of the lower flange portion, a horizontal portion is provided which connects the upper end and faces the glass plate. In this way, even if the lower flange abuts the lower surface of the glass plate due to the rotation of the protective ring, it is difficult to damage the lower surface of the glass plate. In addition, the end of the horizontal part is facing away from the glass at the time of “bouncing”. Since the end surface of the horizontal part does not abut the bottom of the glass plate, even if there is an edge or burr on the end surface of the horizontal part, the bottom of the glass plate can be reliably prevented damage. 5 [Embodiment] An embodiment of the gas furnace according to the present invention will be described below with reference to Figs. 1 to 4. In Figures 1 to 4, the gas furnace is constructed by covering the upper surface 52a of the furnace body 52 with a glass panel 10. The furnace main body 52 is formed by a rectangular box with an open upper surface, and the flange portion 52b bent and formed on the upper end of the peripheral wall of the furnace main body 52 is locked at the periphery of the opening 53a provided on the fluidized countertop of the systematic kitchen. The opening 53 a provided on the fluid table 53 is suspended. The glass panel 10 includes a heat-resistant glass plate (ceramic glass) 2, a protective body 3 surrounding the outer peripheral edge portion thereof, and a protective ring 20 provided at each position on the left and right sides of the glass plate 2 and attached to the opening peripheral edge of the burner opening 2a. Further, the gas burner 54 housed in the main body 52 of the furnace 15 faces the burner opening 2a, and the fire stand 55 is placed outside the protective ring 20 of the glass plate 2. In Fig. 4, reference numeral 56 denotes a thermocouple for detecting that the burner 54 has stopped being ignited, and 59 is a soup cover covering a gap between the flame guide member 58 and the protective ring 20. The protective body 3 is a supporting frame that supports the outer peripheral edge portion of the glass plate 2, but at the same time 20 is a member that protects the outer peripheral edge portion of the glass plate 2. Therefore, in the present invention, the protective body 3 means a buffer material interposed between the outer peripheral edge portion of the glass plate 2 and the support frame. In this embodiment, the protective body 3 is assembled to form a rectangular shape with two front and rear long frame materials 4, 5 and two short and right frame materials 6, 7 between the frame materials 4, 5, 6, and 7. There is a setting area for the glass plate 2 to support the outer periphery 8 of the glass plate 2 200424484 彖 邛 In this example, the back 4 pieces of 8 are spaced behind the frame material 7 at the rear of the protective body 3 to place the frame material 5, 6, 7. An opening is formed between the rear pieces 8. The opening 11 can serve as a suction port. A cover-like guide 57 for introducing air into the opening 11 can be placed between the rear face 5 and the rear piece 8. The rear 4 pieces 8 form a cross-sectional structure with a flange P8b protruding horizontally from the lower end of the vertical wall ^ to the inside and a flange raised upwardly curled downward from the upper end of the vertical wall 8a to the outside, and the front frame material 4, left and right The frame materials 6 and 7 have the same structure. The longitudinal ends of the frame materials 4, the left and right frame materials 6, 7, and the rear sheet 8 are narrowed inward and inclined at an angle of 45 degrees. The rear frame material 5 is formed with a cross-section of the edge portion that horizontally protrudes forward from the lower end of the vertical wall 5a. The edge portions of the long end portions of the rear frame material 5 are narrowed toward the inside and at an angle of 45 degrees. tilt. The rear panel 8 and the right frame material 7 are formed by converging the inverse-diagonal head 8M provided at the edge and end of the rear panel 8 and the 15-diagonal recess 7bl provided at the end of the edge 7b of the frame 7 While combined. The rear sheet 8 and the left frame material, the front frame material 4 and the left frame material 6, the front frame material 4 and the right frame material 7 are similarly combined, and the four frame materials 4, 6, 7, and the rear sheet 8 Assembled into a frame. The rear frame material 5 and the left frame material 6 are formed by converging an inverted triangle-shaped head 5M provided on the edge portion 5b of the rear frame material 5 and a triangular-shaped concave portion 6M provided on the edge portion 6b of the left frame material 6. Combined. The rear 20 frame material 5 and the right frame material 7 can be similarly combined. The supporting portion of the glass plate 2 is formed by a rectangular supporting frame edge, and the supporting frame edge is formed by the horizontal edge portions 4b, 5b, 6b, 7b of the front and rear frame materials 4, 5, and the left and right frame materials 6, 7, and The glass plate 2 is placed on the support portion. Between the placed glass plate 2 and the vertical walls 4a, 5a, 6a, 9 200424484 7a of these frame materials 4, 5, 6, 7 can be filled with Wei seam material $ as a buffer material, so that the glass plate 2 Does not deviate from the protective body 3 to securely hold and ensure water tightness. The protective ring 20 is composed of an upper ring η and a lower ring a, and the upper and lower rings η, 22 include a tube portion that can be inserted into the burner opening 2a] ^, 2 讣, and the opposite 5 glass plates 2 ^^ mouth peripheral edge The upper and lower flange portions ⑴, 22a are formed on the upper surface and the lower surface of the opening periphery. In this example, the cylindrical portion 22b of the lower ring 22 is inserted into the burner opening 2a with a certain gap, and the cylindrical portion 21b of the upper ring 21 is fitted into the inner periphery of the cylindrical portion 22b of the lower ring 22. This gap has a size that does not apply force to the inner peripheral surface of the burner opening 2a of the glass plate 2 even if the protective ring thermally expands. 10 The cylindrical portions 21b and 22b of the upper and lower rings 21 and 22 have a length that fits substantially full length in the vertical direction, and one of them, for example, is formed on the cylindrical portion 21b of the upper ring 21 in a plurality of circumferential directions. The engaging hole 21c is formed with a plurality of protrusions 22c on the cylindrical portion 22b of the lower ring 22 in a plurality of circumferential directions protruding inward in the diameter direction. Further, each protrusion 22c is engaged with each of the engagement holes 21c, so that the upper and lower rings 21 and 22 are not separated, so that the two cylindrical portions 21 and 22 are combined. By mounting such a protective ring 20 on the opening periphery of the burner opening 2a of the glass plate 2, the opening periphery can be protected. In addition, although the protrusion 22c is formed as a cut-and-raised claw, it may be formed as an embossed protrusion. Furthermore, a spacer 23 is inserted between the upper flange portion 21a and the glass plate 2, and the 20 gasket 23 prevents the cooking juice overflowing from the cooker from passing through the gap between the upper ring 21 and the glass plate 2 through the burner opening 2a. Winding under the glass plate 2 can surely prevent the overflowed boiling juice from falling into the furnace body 2. Further, a spacer 24 for protecting the glass plate 2 is interposed between the lower flange portion 22 a and the glass plate 2. In this embodiment, an annular recessed portion 22d is provided in the lower flange portion 22a, and the lower portion of the gasket 24 on the lower side of the glass plate 2 is inserted and held in the recessed portion 22d. A horizontal portion 22f opposed to the glass plate 2 and the narrow gap is continuously provided on the upper end of the recessed portion 22d over the entire peripheral portion of the annular EJ portion 22d of the lower flange portion 22a. Since the gasket 24 inserted on the lower side of the glass plate 2 is crimped to the glass plate 2 by combining the upper and lower rings 21 and 22, a sliding force is generated by the lower flange portion 22 & 24 can be easily separated in the diameter direction by the lower flange portion 22a and come off. As described above, the lower flange portion 22a is provided with an annular recessed portion 22d. If the gasket 24 is held in the recessed portion 22d, the radial movement of the gasket 24 can be restricted, so that the gasket 24 can be prevented from moving from the upper flange portion 22a. Drop off the diameter. Moreover, as long as the recessed portion 22d is provided, the gasket 24 can be easily positioned, and assembly when the guard ring 20 is mounted is simplified. Moreover, if the horizontal portion 22f is provided on the outer peripheral portion of the recessed portion 22d to face the glass plate 2, even if the lower flange portion 22 abuts the lower surface of the glass plate 2, it is difficult to damage the lower surface of the glass plate 2. However, if the protective ring 20 rotates, the outer periphery of the upper flange portion 2ia hangs on the peripheral surface of the burner opening of the lower 2Id grinding burner glass plate 2, and the cylindrical portion 22b of the lower ring 22 rubs inside the burner opening of the glass plate 2. There is a risk of damage to the surface, and there is a danger of damaging the surface. Therefore, in the present invention, an extension 22e is provided in the lower flange portion 22a as a means for preventing the protection ring 20 from rotating. The extension portion 22 extends horizontally unidirectionally from the horizontal portion 22f of the lower flange portion 22a with a width approximately the same as the diameter of the lower flange portion 22a, and has one of the protective bodies 3 reaching and contacting the glass plate 2. length. In this embodiment, the extension portion 22e is extended to be parallel to the left and right frame materials 6 and 7 of the protective body 3 behind the glass plate 2 and reaches and contacts the lower end of the vertical wall 5a of the frame material 5 behind the protective body 3 and extends horizontally forward. The front end of the edge portion 5b. 200424484 It is desirable to provide downwardly bent pieces 22el on both sides in the width direction of the extension portion 22e. In this way, not only the plate thickness of the extension portion 22el can be used to make contact with the front end of the edge portion 5b, but also the height direction can be obtained by the curved piece 22el, so the front end of the edge portion 5b can be easily contacted, and the edge portion can be reliably contacted The front ends of the 5 parts 5b are in contact. Further, by increasing the rigidity of the extension portion 22e by the curved piece 22el, the extension portion 22e can be prevented from being deformed. Although the longer the curved piece 22el is, the better the rigidity is, but W in the figure is not 0, that is, at least the cylindrical portion 22b and the curved piece 22el need only overlap with each other. According to this embodiment, if a person cleans the glass panel 10 or the like and contacts the abrasive ring 10 with the protective ring 20, the contact portion between the extended portion 22e of the lower flange portion 22a and the edge portion 5b of the rear frame member 5 becomes the protective ring 20. Rotate the resistance so that the guard ring 20 will not rotate. Therefore, the gasket 23 does not cause the burner opening 2a of the glass plate 2 to scratch the opening peripheral surface or the opening inner peripheral surface of the glass plate 2 or the gasket 23 inserted between the glass plate 2 and the protection 20 due to the friction loss of the protection ring 20 Or 24, as a result, the pad 15 has a disadvantage of Delo Temple. Also, since the cymbal 24 is held in the annular recessed portion 22d provided in the lower flange portion 22a to restrict the movement of the gasket 24 in the radial direction, it is possible to prevent the spacer 24 from falling away from the lower flange portion 22a. In addition, by using the recessed portion 22d, the gasket 24 can be easily positioned, and assembly at the time of attaching the protection ring 20 can be simplified. Moreover, since the horizontal portion 22d provided on the outer peripheral portion of the recessed portion 22d faces the glass plate 2, that is, the lower flange portion 22 contacts the lower surface of the glass plate 2, it is also difficult to damage the lower surface of the glass plate 2. Hereinafter, another embodiment of the present invention will be described with reference to FIGS. 5 to 7. In this embodiment, the glass panel 30 of the gas furnace, the burner opening 2a is provided near the left and right positions before the glass plate 2, and a combustion chamber having a smaller diameter than the burner opening 2a is also provided behind the left and right burner openings 2a.

In addition, the horizontal portion i5a of the holder 15 is formed inside the protruding piece 15b and the curved piece facing the other side can also serve as a contact portion. In this conventional practice, even if the friction protection rings 20, 20A are contacted by a person cleaning the glass panel 30, etc., the protection rings 20, 20A will not rotate, and will not wear 14 200424484 Abrasion damage to the glass plate 2 The peripheral surfaces of the openings 2a, 2b of the burner or the inner peripheral surface of the burner opening, or the frictional wear of the protective ring is inserted between the glass plate 2 and the protective ring 20, 20A, and as a result, the gasket falls off. In the embodiment shown in FIG. 8, the left and right frame materials 131 and 141 used for the front and rear frame materials 16 and 17 are replaced by the left and right frame materials 13 and 14 of the protective body 3 in FIG. 5, and the front and rear frame materials 161 and 171 ( Only the rear frame material 141 is shown), and there is no lower sheet, and for example, the horizontal portion 151a of the holder 151 mounted on the frame materials 141 and 161 and the upper piece 141a, the side piece 141b, and the horizontal portion 152a of the frame material 141 and The top sheet and the side sheet of the frame material 161 can hold the adjacent side edge portions of the glass plate 2 on which the gasket 12 is mounted. Off 10 The same applies to the frame materials 141 and 171 and the fixtures mounted here, the frame materials 131 and 171 and the fixtures fitted thereto, and the frame materials 131 and 161 to the fixtures mounted here. In this embodiment, the extension 22e of the flange portion 22a1 of the lower ring 22 of the protective ring 20 has been extended to the side of the glass plate 2 parallel to the front and rear frame materials 161 and 171 to contact the right frame material 13 The front end of the lower sheet da of the pad 12 of Bu 141. In addition, in this example, it is also possible to contact other components other than the pad 12 of the protective body 3, that is, the horizontal portions of the left and right frame materials 131, ⑷, the front and rear frame materials i6i, i7i, or the holder 151. 20. In the embodiment shown in FIG. 9, the outer frame of the protective body 3 of the panel is processed by punching with a stainless steel plate to form a frame-like frame portion. The frame-like frame portion 18 includes a horizontal upper surface portion 18a throughout the entire periphery, and the center of the upper surface portion continues to the downwardly-inclined inclined portion 18b and the volume of the involute coil connected to the sloping part-machi end. Near the upper end of the curled portion 18e, mounting angles from a plurality of longitudinal positions protrude horizontally, and the end portion of the mounting portion 18d is bent upward to form a vertical portion 18e. In addition, the upper portion 18a is formed near the inner portion to form an inwardly inclined portion 18f slightly downward. Alignment δ is again placed on the mounting portion 18d of the frame portion 18 as the protective body 3 and the screw holes (not shown) of the holder 19, and then the holder 19 is mounted on the jacket 418d by screws 19a. In this way, the side edge portion of the glass plate 2 can be held and mounted by the fixed portion 19, the vertical portion ^ of the frame portion 18, and the upper inclined portion 18f. In this embodiment, the extension 22e of the flange portion 22a under the protection ring 20 extends toward the holder 19 of the protection body 3 and contacts the front end of the holder 19. The 10 extension portion 22e has a downwardly bent piece 22el similarly to the embodiment shown in Figs. 3 to 6. According to this embodiment, the same effect as that of the previous embodiment can be achieved. Figures 10 to 11 show another embodiment of the present invention.

And placed on the kitchen countertop 53. The glass panel 40 covering the opening 32a on the upper surface of the furnace body 32 is formed by surrounding the glass plate 2 with a frame-shaped protective body 43. The protective body 43 is such that a horizontal portion 43b suspended from the inner peripheral end of the horizontal flange portion 43a contacts the upper surface of the outer peripheral portion of the glass plate 2, and a lower portion 43c suspended from the outer peripheral end of the flange portion 43a is suspended to a horizontal position. The side wall 34 of the furnace body 32 is near the upper portion 34 a to be disposed on the furnace body 32. The lower end portion of the lower portion 43c forms a folded portion 43d facing inward. In addition, the glass plate 2 is bonded to the sealing material K with a protective body 43. 16 200424484 At the periphery of the burner opening 2a of the glass plate 2, a protection ring 20 composed of 2m and 22 is installed in the same way as the former, and the facing furnace body is not provided on the flange 22a of the lower ring 22. An extension 22e extending in the direction of the side wall 34 of 32. In Figs. 10 to 11, the same symbols as those in Figs. 9 to 9 indicate the same components. In this embodiment, curved pieces 27 facing downward at the top of the extension portion 22e are replaced with downward curved pieces provided at both sides of the extension portion 22e. Further, an upper edge portion 35 of the upper opening 32a of the furnace body 32 which is partitioned inwardly from the upper end of the side wall 34 of the furnace body 32 is provided with a receiving piece 28 which is in contact with the curved piece 27. The receiving piece 28 is composed of a plate having a cross-section L-shape having a rectangular cutout portion 29 at the horizontal portion 28a, and the vertical portion 28b of the receiving piece 28 is brought into contact with and retracted to the upper side of the side portion 34a of the side wall 34 above the side wall portion. 34b is attached to the upper edge portion 35. In order to prevent interference between the receiving piece 28 and the glass plate 2, a recessed portion 35b having a horizontal portion 35 & is formed on the upper edge portion, and the horizontal portion 28a of the receiving piece 28 is mounted on the level of the concave iron portion 35 with a screw 28c.部 35a。 35a. The bent piece 27 below the top end of the extension 22e of the downward flange 22 extends into the cutout portion 29 of the receiving piece 28 mounted on the upper edge portion 35 of the side wall 34 of the furnace body 32 to contact the inner side surface of the cutout portion 29. Therefore, even if the friction protection ring is contacted by a person cleaning the glass surface 20 plate 40 or the like, the contact portion between the extension portion 22e of the lower flange 22a and the notch portion 29 of the receiving piece 28 will become resistance to the rotation of the protection ring 20, so that The guard ring 20 does not rotate. As described above, although the receiving piece 28 is provided by screwing to the side wall 34 of the furnace body 32, the receiving piece 28 may be directly formed on the side wall 34. Also, although the extension 22e of the lower flange 22 of 17 200424484 is provided with a downwardly bent piece 27 and the receiving piece 28 is provided with a notch 29, the receiving piece 28 may be provided with a downwardly bent piece 27, and A sigma-deficient portion 29 is provided on the extension portion 22e of the lower flange 22b. Moreover, the receiving piece 28 may not be provided on the side wall 34 of the furnace body 32, and the curved piece 27 below the extension 22e of the downward flange 5 22b directly contacts the inner surface of the side wall 34 of the furnace body 32 to prevent the protective ring 20 Swirl. In this example, it is also possible to form a receiving recessed portion of the gasket 24 in the lower flange 22a. Figure 12 shows another embodiment of the present invention. In this embodiment, the protective ring 20 attached to the peripheral portion of the burner opening 2a of the glass plate 2 of the panel is under the lower garment 38. The flange 38a 'is the same as the previous implementation. The shape of the lower flange 22a of the lower ring 22 is different. In Fig. 12, the same symbols as those in Fig. 2 indicate the same members. Therefore, in order to prevent the gasket 24 inserted on the lower side of the glass plate 2 from falling off, etc. even if the rotation is guaranteed, the lower flange portion 38a is provided with a ring-shaped recess 38d, 15 and inserted under the glass plate 2. The lower part of the side gasket 24 is accommodated and held in the recess 38d. A horizontal portion 38f opposed to the glass plate 2 with a narrow gap is continuously provided on the upper end of the concave portion 38d over the entire periphery of the annular concave portion 38d of the lower flange 38a. The end portion 38e of the horizontal portion 38f is bent in a direction away from the broken glass plate 2 as shown in Fig. 12 (b). It is desirable to form a foldable inside 20 as shown in Fig. 12 (a). Of the folded section. In Fig. 12, reference numeral 38b denotes a cylindrical portion of the lower ring 38, and 38c denotes an engaging piece thereof. The gasket 24 inserted on the lower side of the glass plate 2 is crimped to the glass plate 2 by combining the upper and lower rings 21 and 38. Therefore, by the rotation of the protection ring 20, a sliding force can be generated by the lower flange portion 38a to make the gasket 24 It is easy to fall away from the lower flange portion 38a in the radial direction. 18 However, as described above, as long as the annular concave portion 38d is provided in the lower flange portion 38a, and the gasket 24 is held in the concave portion 38 (1, the diameter of the gasket 24 can be restricted. The movement in the direction prevents the gasket 24 from falling away from the upper flange portion 38a in a radial direction and falling off. Moreover, as long as the recessed portion 38d is provided, the gasket 24 can be easily positioned, and assembly at the time of mounting the protection ring 20 becomes simple. In addition, as long as the horizontal portion 38f is provided on the outer periphery of the recessed portion 38d to face the glass plate 2, even if the lower flange 38a abuts the lower surface of the glass plate 2, it is difficult to damage the lower surface of the glass plate 2 because the lower surface contacts the lower surface of the glass plate 2. However, as shown in FIG. 12 (c), when the horizontal portion 38f ^ end portion 38e is still horizontal, if there is an edge or burr on the end surface of the horizontal portion 38f, the lower flange 38a abuts the lower surface of the glass plate 2 , There is a possibility that the lower surface of the glass plate 2 is damaged. In this embodiment, as described above, since The end portion 38e of the horizontal portion 38f is bent away from the glass plate 2. The end surface of the horizontal portion 38f does not abut the lower surface of the glass plate 2. Even if there is an edge or burr on the end surface of the horizontal portion 38f, damage can be reliably prevented. The lower surface of the glass plate 2. When the end portion 386 of the horizontal portion 38f is formed as a folded portion folded inside, the damage prevention effect of the glass plate 2 can be further improved. As can be seen from the above description, according to the present invention, the outer periphery of the glass plate is protected by a protective body. The edge of the glass panel, as the lower flange of the protective ring installed on the peripheral edge of the opening of the glass plate burner reaches and contacts one of the protective body or the furnace body to prevent the extension of the protective clothing from rotating. When cleaning, etc. On this occasion, the protection ring can be prevented from damaging the glass plate, or the gasket inserted between the protection ring and the glass plate can be worn or lost. In addition, the lower flange portion is provided with a ring that accommodates the gasket inserted under the broken glass plate. The shape of the concave portion can prevent the gasket from radially deviating from the lower flange portion and falling off.
