The technical field to which the invention belongs 3 The technical field to which the invention belongs The present invention relates to a gas furnace using a heat-resistant plate as the top plate, and more specifically, it relates to a technique for preventing the top plate from cracking. C Prior art 3 In recent years, from the standpoint of beauty or ease of packing, the use of heat-resistant plates made of glass, such as glass, has increased in the top plate of gas stoves. However, if the glass top plate is subjected to an excessive load due to a pan, The vicinity of the opening faced by the burner is bent and easily broken from the opening. The conventional gas furnace has a supporter in which the opening portion of the top plate is a burner tube or a burner body support (refer to Patent Document 丨). With this structure, a load acting on the opening portion acts on the burner body, etc., and Prevents the top plate from bending. 15 Patent Document 1: Japanese Patent Laid-Open Publication No. 10-169918. Problems to be Solved by the Invention However, the aforementioned structure has a large burden on the burner body and the like, and it cannot be denied that there are safety problems such as deformation of the flame mouth portion. Therefore, the 20 purpose of the gas furnace according to the present invention is that the burden does not act on the burner body and the like, and it reduces the bending caused by the load acting on the opening of the top plate and prevents the top plate from breaking. It is also stated that the top plate is particularly prone to cracking due to the impact of the end surface of the opening portion, and has the problem of being broken by other metal parts touching the end surface of the opening portion during transportation. Therefore, the second purpose of the gas furnace of the present invention is to protect the end surface of the top plate and 5 200404143 Prevent the top plate from cracking. C. Summary of the Invention 3 Means, Action, and Effect of Solving the Problem 5 10 15 20-~, a casing with an upper opening, a burner supported by the casing, and a glass-filled plate-shaped member. The plate key cover has a Γ portion, and has an opening portion at a portion corresponding to the burner. The aforementioned tile furnace has a top plate tilting member, the Wei protection member_upper and lower opening guards = a tubular member, and a water bucket supporting the opening edge below the top plate = water: the end portion extends downwards to the lower portion. In addition, the front _ is a support pad having the shape of a cross section] and covering the peripheral edges of the upper and lower openings of the top plate and the _ face of the opening of the top plate, and also has a top plate support plate. The top plate support plate extends in a vertical direction. A plate-shaped member, and a top plate protection member is placed on the upper end thereof, and the lower end is connected to the bottom of the casing. In this gas furnace, when a steel or the like is placed on a fire rack, the steel rack moves toward the support frame, and then, the load moves toward the top plate protection structure f toward the top plate support plate for supporting the top plate protection member, and the bottom plate moves The negative part of the opening faced by the burner of the top plate is cut and cut, and the negative shirt will act on the opening of the top plate for the bottom of the cymbal. Thus, the top plate curvature caused by the negative can be recorded to prevent cracking.
又，前述瓦斯爐宜具有從頂板保護構件之水平部内周 緣朝上方延伸且與頂板開 口部内側面相對之上部，且在頂 叛開二部_面與雜保護構件之上㈣配置填縫構件。 右頂板為破螭板，則容易因開口部端面受到衝擊而破 6 200404143 裂。又，玻璃板會因燃燒器加熱時開口部變成高溫而膨脹 並產生變形或應變，此亦容易導致破裂。 前述瓦斯爐係於頂板開口部内側面與頂板保護構件之 上口P間配置填縫構件。藉由該填縫構件，可保護頂板開口 5部之内側面且防止頂板開口部之高溫化，藉此，可保護容 易破裂之端面並防止頂板變形或應變，且可防止頂板破裂。 發明之實施形態 以下說明本發明之較佳實施形態。 10 ⑽111)71㈣耐熱強化玻璃製頂板。於頂才反具有3個燃 燒器所面對之開口部。這些開口部之内侧面與下面開口部 周緣係藉由頂板保護構件來支持。該頂板保護構件之下端

之開口部附近之分解立體圖，第3圖係同-瓦斯爐之主要部 分縱截面圖。另，在此所表示之圖係用以說明本實施例之 特徵，有關構成構件之形狀等未必要與實際構造相同。 200404143 第1圖所示之瓦斯爐10係具有3個大小燃燒器12a、 12b、12c與收納這些燃燒器之殼體14，以及覆蓋殼體14之 上部開口部之頂板16。該瓦斯爐10係嵌入式爐具，且殼體 14裝入設置在廚房流理台（18 :參照第3圖）之安裝孔（18a : 5 參照第3圖），且頂板16係以同時覆蓋殼體14之開口部與廚 房流理台18之安裝孔18a來載置（參照第3圖）。於頂板16上配 置有3個開關20a、20b、20c，且藉由這些開關分別進行燃 燒器12a、12b、12c之點火·媳火動作或火力調節。 於頂板16設有3個燃燒器12a、12b、12c所面對之開口 10 部16a、16b、16c。利用第2、3圖說明該頂板16之開口部16a、 16b、16c附近之構造。另，各開口部16a、16b、16c附近之 構造大致相同，在此，利用開口部16a附近之說明而省略其 他開口部16b、16c附近之說明。 第2圖係藉由分解立體圖顯示開口部16a與構成其附近 15 之主要構件。於頂板16之開口部16a附近，除了第1圖中所 顯示之火架22以外，尚配置有圓板狀之湯汁承接盤24、環 狀之支持墊26、略呈圓筒狀之頂板保護構件28與垂直地延 伸之板構件之頂板支持板3〇。 湯汁承接盤24係金屬製構件且中央具有開口部24a，而 20 燃燒器文式管32之上端係從下方插入。又，於湯汁承接盤 24係形成開口部24a與同心圓狀之階部。接連形成開口部 24a之階部24b而於外侧形成低1階之階部24c，且接連該階 部24c而於外側形成高1階之階部24d，再接連該階部24d而 於外側形成高1階之階部24e(參照第3圖）。外側階部24e最 8 200404143 高，從内側起之第2階部24c最低。火架22係擺在從外側起 之第2階部24d。調理中溢出之湯汁會被攔在内側階部24b而 留在階部24c，大致上不會流入殼體14内。 支持墊26係矽製構件，且截面略呈〕字形。湯汁承接 5盤24係擺在該支持墊26之上端。詳細情形留待後面利用第3 圖來作說明。 頂板保護構件28係金屬製，且由上部28a、水平部28b、 下部28c與凸緣28d所構成，上部28a係垂直地延伸，水平部 b係從該上部28a下端朝外側水平地延伸，下部28〇係從該水 1〇平部28b外侧端部朝下方垂直地延伸，凸緣28d則從該下部 28c下端朝外側水平地延伸。詳細情形亦留待後面利用第3 圖來作說明。 頂板支持板30係金屬製，且2個頂板支持板30係夾住略 呈L字形之燃燒器文式管32之垂直部分且相對地配置。頂板 15 支持板3〇之上端與下端分別設有凸緣30a、30b。燃燒器文 式管32係螺釘固定於安裝台34。於安裝台34設有凸緣34a， 且載置燃燒器文式管32之面形成為比該凸緣34a高1段。詳 細情形亦留待後面利用第3圖來作說明。 第3圖係通過頂板16之開口部16a中心且相對於瓦斯爐 20 1〇之正面而以平行之平面縱切之圖。 於廚房流理台18之安裝孔18a係裝入殼體14。詳而言 之，於殼體14上端係形成凸緣14a，且該凸緣14a係於由厨 房流理台18之安裝孔18a周緣支持之狀態下設置。 頂板16之外周緣係由金屬製頂板框36支持。詳而言 9 之，頂板16之外側面與頂板16下面之外周緣係由頂板框36 支持。該頂板框36係由廚房流理台18之安裝孔i8a周緣支 持。 頂板16係耐熱強化玻璃製頂板，且若受到衝擊則有破 裂之虞，特別是容易從端面破裂。故，於頂板16外側面與 頂板框36間配置有矽製填縫38。該填縫38係藉由使頂板16 之外側面未與金屬製頂板框36直接接觸且吸收頂板16水平 方向之移動，而扮演因衝擊而保護頂板外侧面之角色。又， 於頂板16下面之外周緣與頂板框36間配置有矽製之墊4〇， 且扮演著使頂板16下面之外周緣未與頂板框36直接接觸之 角色。 頂板16之開口部16a周緣係如下述來支持。頂板16之開 口部16a内側面與開口部16a下面之内周緣係藉由頂板保護 構件28之上部28a與水平部28b來支持。如前所述，由於頂 板16受到衝擊則會有破裂之虞，特別是端面容易破裂，因 此，於頂板16之開口部16a内側面與頂板保護構件28之上部 28a間配置有矽製填縫42。該填縫42係藉由使頂板16之開口 部16a内側面未與金屬製頂板保護構件28直接接觸而扮演 因衝擊而保護頂板開口部16a内侧面之角色。又，於頂板16 之開口部16a下面之内周緣與頂板保護構件28之水平部28b 間配置有矽製之墊44,且扮演著使頂板16之開口部16a下面 之内周緣未與頂板保護構件28直接接觸之角色。 如前所述，於頂板16之開口部16a周緣係藉由填縫42與 墊44而安裝頂板保護構件28。支持墊26係安裝為從上下方 200404143 向夾住安裝有該頂板保護構件28之頂板16開口部16a周 緣。該支持墊26係截面略呈^字形，且於形成為高一階之 階部26a上端面擺上湯汁承接盤24外侧之階部24e。 另’湯汁承接盤24之外周緣係朝下方彎曲。若火架22 5擺在湯汁承接盤24且鍋子等擺在該火架22上，則湯汁承接 盤24會因負載而向下方按壓支持墊26之階部26a。藉此，支 持墊26沈入下方，湯汁承接盤24亦隨之沈入下方。此時， 為了使湯汁承接盤24之外周緣不會接觸頂板16，故預先於 湯汁承接盤24之外周緣與頂板16間設置間隙a。 10 刖述頂板保護構件28係由頂板支持板3〇支持。詳而言 之，設置於頂板保護構件28下端之凸緣28d係固定於設置在 頂板支持板30上端之凸緣3〇a。設置於頂板支持板3〇下端之 凸緣30b係與設置在燃燒器文式管32之安裝台34之凸緣3如 重疊，且螺釘固定於殼體14之底部。 15 燃燒器12&係由燃燒器文式管32、載置於其上端之燃燒 器本體46與擺在前述燃燒器本體46上之燃燒器頭48所構 成。燃燒器文式管32係設置於安裝台34上，且於燃燒器文 式管32與殼體14底部間設有空間b。在燃燒器12a燃燒時燃 燒器文式管3 2會變成高溫，但因空間b而可減少殼體14底部 20 之加熱。 於頂板設置有燃燒器所面對之開口部，且於該開口部 附近載置有鍋子等。耐熱強化玻璃製之頂板有可能會因受 到衝擊而破裂。即，載置鍋子等時若受到過大之負載，則 頂板有可能會從開口部破裂。若如以往構成為頂板由燃燒 11 200404143 器本體等來支持，則負載作用於燃燒器本體等且產生焰口 部變形等安全性問題。 、/於本實施例之瓦斯爐1〇中，锅子等擺在火架時之負 載係如下述來作用。作用於火架22之負載係朝支持火架22 5之湯汁承接盤24移動，且朝支持湯汁承接盤24之支持墊％ 移動。支持塾26會吸收-定程度之負載，而未被吸收之部 分之負載則朝支持頂板16之開口部16a周緣之頂板保護構 件28移動。頂板保護構件28係其下端由頂板支持板3〇支 持，且負載朝頂板支持板30移動後朝殼體14底部移動。即， 10頂板16之開口部16a、16b、⑹係藉由前述構件而從下方支 持，且鍋子等之負載不會作用於頂板16之開口部16a、16b、 16c而作用於殼體14底部。藉此，可防止因負載產生之頂板 16之彎曲而防止破裂。 耐熱強化玻璃製之頂板特別容易因端面受到衝擊而破 15裂。又，在燃燒器加熱時開口部會變成高溫而膨脹，且造 成變形或應變並產生破裂。 本實施例之瓦斯爐10係於頂板16之開口部16&、16b、 16c之内側面與頂板保護構件28之上部28a間配置有矽製填 縫42。藉由該矽製填縫42，保護頂板16之開口部16&、i6b、 20 16(：之内側面，藉此，可保護容易破裂之端面，且可防止頂 板16破裂。 由前述可知，本發明之瓦斯爐係防止負載作用於頂板 開口部附近且保護頂板開口部之端面，藉此可防止頂板破 裂0 12 另，前述實施例係於頂板16外緣配置頂板框36，且開 口部16a之内側面係藉由頂板保護構件“之上部來保 護，然而，例如，若頂板使用厚板強化玻璃時，則可廢除 頂板保護構件28之上部28a，且亦可廢除用以保護開口部 16a之内側面所配置之填縫42與墊44。即，如第4圖所示， 直接以支持墊26夾住開口部56a，且使藉由該支持墊26夾住 之開口 σ卩56a載置支持餘頂板保護構件58之水平部58b。頂 板56之外緣係藉由墊50而載置於廚房流理台18之開口部 18a附近。若藉由此種構造，則亦可得到與前述實施例所示 之構造相同之效果，且可進一步減少零件數並提升作業效 率。 又，前述實施例係於支持墊26上方載置有火架22，然 而’亦可將火架22直接載置於支持塾26上。即，如第5圖所 示，將湯汁承接盤54之内周端54b載置於燃燒器文式管32之 P白《卩32a上，且直接將火架22載置於支持墊26上。若依此構 成’則亦可得到與前述實施例所示之構造相同之效果。 以上詳細说明本發明之具體例，然而，這些例子只不 過是舉例，並非限定申請專利之範圍，申請專利範圍所記 載之技術亦包含將前述所舉之具體例作各種變形、變更者。 又，本說明書或圖式所說明之技術要素可單獨或藉由 各種組合來發揮技術之有用性，並不限於申請時申請專利 範圍中所記載之組合，又，本說明書或圖式所列舉之技術 係同時達成複數目的，達成其中之一之目的本身亦具有技 術之有用性。 200404143

extending upward from the inner peripheral edge of the horizontal portion of the top plate protection member and opposite to the inner side surface of the opening portion of the top plate, and a caulking member is disposed on the top surface of the second portion and the miscellaneous protection member. The right top plate is a broken plate, and it is easy to break due to the impact of the end face of the opening. In addition, the glass plate expands due to the high temperature of the opening when the burner is heated, and deforms or strains, which may easily cause cracks. The gas furnace is provided with a caulking member between the inner side surface of the ceiling opening and the upper opening P of the ceiling protective member. This caulking member can protect the inner side surface of the top plate opening 5 and prevent the top plate opening from becoming high temperature, thereby protecting the end surface that is easily broken, preventing deformation or strain of the top plate, and preventing the top plate from cracking.

The top plate 16 is provided with three switches 20a, 20b, and 20c, and these switches are used to perform ignition / beacon operation or fire power adjustment of the burners 12a, 12b, and 12c, respectively. The top plate 16 is provided with 10 openings 16a, 16b, and 16c facing three burners 12a, 12b, and 12c. The structures in the vicinity of the openings 16a, 16b, and 16c of the top plate 16 will be described with reference to Figs. The structures in the vicinity of each of the openings 16a, 16b, and 16c are substantially the same. Here, descriptions in the vicinity of the openings 16a are used, and descriptions of the other openings 16b and 16c are omitted. Fig. 2 is an exploded perspective view showing the opening portion 16a and the main members constituting the vicinity 15 thereof. Near the opening 16a of the top plate 16, in addition to the fire rack 22 shown in FIG. 1, a circular plate-shaped soup receiving tray 24, a ring-shaped support pad 26, and a slightly cylindrical top plate protection are arranged. The top plate support plate 30 of the member 28 and the vertically extending plate member. The soup receiving pan 24 is a metal member and has an opening 24a in the center. The upper end of the 20 burner tube 32 is inserted from below. Further, an opening portion 24a and a concentric circular step portion are formed in the soup receiving plate 24. The step portion 24b of the opening portion 24a is formed in succession to form a lower-order step portion 24c on the outside, and the step portion 24c is formed to form a higher-order step portion 24d on the outside, and then the step portion 24d is formed to form a high height on the outside. The first-order step portion 24e (see FIG. 3). The outer step portion 24e is the highest 8 200404143, and the second step portion 24c from the inner side is the lowest. The fire stand 22 is placed on the second step portion 24d from the outside. The soup spilled during the conditioning is stopped in the inner step portion 24b and left in the step portion 24c, and does not substantially flow into the casing 14. The support pad 26 is made of silicon, and has a cross-section. The soup receiving tray 5 is placed on the upper end of the support pad 26. The details will be described later using FIG. 3. The top plate protection member 28 is made of metal and is composed of an upper portion 28a, a horizontal portion 28b, a lower portion 28c, and a flange 28d. The upper portion 28a extends vertically, the horizontal portion b extends horizontally from the lower end of the upper portion 28a, and the lower portion 28 The 〇 series extends vertically downward from the outer end portion of the flat portion 28 b of the water, and the flange 28 d extends horizontally outward from the lower end of the lower portion 28 c. The details will be described later using FIG. 3. The top plate support plate 30 is made of metal, and the two top plate support plates 30 are arranged opposite to each other while sandwiching the vertical portion of the burner style pipe 32 which is slightly L-shaped. The upper and lower ends of the top plate 15 support plate 30 are provided with flanges 30a and 30b, respectively. The burner manifold 32 is fixed to the mounting base 34 with screws. A flange 34a is provided on the mounting base 34, and the surface on which the burner tube 32 is placed is formed one step higher than the flange 34a. Details will be left for later explanation using FIG. 3. FIG. 3 is a longitudinal cut through a center of the opening 16a of the top plate 16 and parallel to the front surface of the gas furnace 20 10. A mounting hole 18 a in the kitchen fluidic table 18 is inserted into the casing 14. Specifically, a flange 14a is formed on the upper end of the casing 14, and the flange 14a is provided in a state supported by the periphery of the mounting hole 18a of the kitchen fluid table 18. The outer periphery of the top plate 16 is supported by a metal top plate frame 36. In detail, the outer side of the top plate 16 and the outer periphery of the lower surface of the top plate 16 are supported by the top plate frame 36. The top plate frame 36 is supported by the periphery of the mounting hole i8a of the kitchen fluid table 18. The top plate 16 is a top plate made of heat-resistant tempered glass, and may be cracked when subjected to an impact, and is particularly easy to crack from an end surface. Therefore, a silicon joint 38 is arranged between the outer surface of the top plate 16 and the top plate frame 36. The caulk 38 plays a role of protecting the outer surface of the top plate due to impact by preventing the outer surface of the top plate 16 from directly contacting the metal top plate frame 36 and absorbing the horizontal movement of the top plate 16. A silicon pad 40 is arranged between the outer periphery of the lower surface of the top plate 16 and the top plate frame 36, and plays a role of preventing the outer periphery of the lower surface of the top plate 16 from directly contacting the top plate frame 36. The peripheral edge of the opening 16a of the top plate 16 is supported as follows. The inner side surface of the opening portion 16a of the top plate 16 and the inner periphery of the lower portion of the opening portion 16a are supported by the upper portion 28a and the horizontal portion 28b of the top plate protecting member 28. As described above, the top plate 16 may be broken due to the impact, especially the end surface is easily broken. Therefore, a silicon caulk 42 is arranged between the inner surface of the opening portion 16 a of the top plate 16 and the upper portion 28 a of the top plate protection member 28. . The caulk 42 plays a role of protecting the inside surface of the ceiling plate opening portion 16a due to an impact because the inside surface of the opening portion 16a of the top plate 16 is not in direct contact with the metal top plate protection member 28. A silicon pad 44 is disposed between the inner peripheral edge of the lower portion of the opening portion 16a of the top plate 16 and the horizontal portion 28b of the top plate protecting member 28, and plays a role such that the inner peripheral edge of the lower portion of the opening portion 16a of the top plate 16 does not contact the top plate protecting member. 28 Direct Contact Characters. As described above, the top plate protection member 28 is attached to the periphery of the opening portion 16a of the top plate 16 by the caulk 42 and the pad 44. The support pad 26 is attached from the upper and lower 200404143 to the periphery of the opening 16a of the top plate 16 on which the top plate protection member 28 is mounted. The support pad 26 has a square shape in cross section, and a step portion 24e on the outer side of the soup receiving tray 24 is placed on the upper end surface of the step portion 26a which is formed one step higher. On the other hand, the outer periphery of the soup receiving plate 24 is bent downward. If the fire rack 22 5 is placed on the soup receiving pan 24 and a pot or the like is placed on the fire rack 22, the soup receiving pan 24 will press the step portion 26a of the support pad 26 downward due to the load. As a result, the support pad 26 sinks downward, and the soup receiving tray 24 sinks downward. At this time, in order to prevent the outer periphery of the soup receiving pan 24 from contacting the top plate 16, a gap a is provided between the outer periphery of the soup receiving pan 24 and the top plate 16 in advance. 10 Description The roof protection member 28 is supported by the roof support plate 30. Specifically, the flange 28d provided at the lower end of the top plate protection member 28 is fixed to the flange 30a provided at the upper end of the top plate support plate 30. The flange 30b provided on the lower end of the top plate support plate 30 overlaps with the flange 3 provided on the mounting table 34 of the burner pipe 32, and is screwed to the bottom of the casing 14. The 15 burner 12 is composed of a burner pipe 32, a burner body 46 placed on the upper end thereof, and a burner head 48 placed on the burner body 46. The burner style pipe 32 is provided on the mounting base 34, and a space b is provided between the burner style pipe 32 and the bottom of the casing 14. When the burner 12a burns, the burner manifold 32 becomes high temperature, but the heating of the bottom 20 of the casing 14 can be reduced due to the space b. An opening portion facing the burner is provided on the top plate, and a pot or the like is placed near the opening portion. The top plate made of heat-resistant tempered glass may break due to impact. In other words, if an excessive load is placed on a pan or the like, the top plate may break from the opening. If the top plate is conventionally supported by the burner body, etc., a load is applied to the burner body, etc., and safety problems such as deformation of the flame mouth portion occur. In the gas furnace 10 of this embodiment, the load when a pot or the like is placed on a fire stand acts as follows. The load acting on the fire rack 22 is moved toward the soup receiving tray 24 supporting the fire tray 22 5 and toward the support pad% supporting the soup receiving tray 24. The support 塾 26 absorbs a certain degree of load, and the load of the unabsorbed portion is moved toward the ceiling protection member 28 supporting the periphery of the opening portion 16a of the ceiling 16. The top plate protection member 28 is supported at its lower end by the top plate support plate 30, and the load is moved toward the bottom plate support plate 30 and then toward the bottom of the casing 14. That is, the openings 16a, 16b, and 10 of the top plate 16 are supported from below by the aforementioned members, and a load such as a pan does not act on the openings 16a, 16b, 16c of the top plate 16 and act on the bottom of the case 14. Thereby, it is possible to prevent the top plate 16 from being bent due to a load and to prevent cracking. The top plate made of heat-resistant tempered glass is particularly prone to breakage due to impact on the end surface. In addition, when the burner is heated, the opening portion becomes high temperature and expands, which causes deformation or strain and causes cracking. In the gas furnace 10 of this embodiment, a gap 42 made of silicon is arranged between the inner side surfaces of the openings 16 & 16b, 16c of the top plate 16 and the upper portion 28a of the top plate protection member 28. The silicon caulk 42 protects the openings 16 &, i6b, 20 16 (:) of the top plate 16, thereby protecting the easily broken end surface and preventing the top plate 16 from breaking. The gas furnace of the invention prevents the load from acting near the opening of the top plate and protects the end surface of the opening of the top plate, thereby preventing the top plate from cracking. In addition, the foregoing embodiment is that the top plate frame 36 is arranged on the outer edge of the top plate 16, and the opening portion 16a The inner side is protected by the "upper part of the top plate protection member. However, for example, if the top plate is made of thick plate reinforced glass, the top portion 28a of the top plate protection member 28 can be eliminated, and the inside of the opening portion 16a can be eliminated. The caulk 42 and the pad 44 are arranged on the side. That is, as shown in FIG. 4, the opening portion 56a is directly clamped by the support pad 26, and the support σ 卩 56a sandwiched by the support pad 26 is used to place the support surplus. The horizontal portion 58b of the top plate protection member 58. The outer edge of the top plate 56 is placed near the opening portion 18a of the kitchen fluidity table 18 by the pad 50. With this structure, the same structure as the previous embodiment can be obtained. Shows the same effect as the construction, and The number of parts can be further reduced and the work efficiency can be improved. Also, the foregoing embodiment is that the fire rack 22 is placed above the support pad 26, but the fire rack 22 can also be directly placed on the support cymbal 26. That is, as in the fifth As shown in the figure, the inner peripheral end 54b of the soup receiving tray 54 is placed on the P white "卩 32a" of the burner tube 32, and the fire rack 22 is directly placed on the support pad 26.
