I: Previous technology 3 Known technology At present, a kitchen equipped with a built-in cooker with a built-in stove on a workbench of a conditioning table is known. The built-in stove is covered by a top plate with an opening facing the gas burner 10, and covers the upper surface of the stove body containing the gas burner, and the flange at the upper end of the peripheral wall of the stove body is locked on the stove body. The top of the workbench is suspended from the opening of the workbench. In this type of built-in stove, if the front of the stove body is exposed to the user side under the work table, an operation part can also be provided on the front of the stove, and the front can be formed into a ventilation port, etc., so it can take in combustion air or cool it. With air. However, if the front of the stove main body is not exposed to the user side under the work table and the operation section is set on the top plate, the vent cannot be provided beside the operation section. In addition, in order to prevent the heat in the stove body from diffusing to the outside as much as possible, the stove body needs to be tightly sealed, so it is impossible to take in primary combustion air from around the stove body. Therefore, it is known from Patent Document 1 below that a built-in furnace in which an opening is provided on a hanging wall around the top plate and the opening is used as a vent is known. According to Patent Document 1, even if it is a stove body with high airtightness, it is possible to take in combustion air into the stove body through a transparent and rain port. However, A 7 + has fully ensured the 1227770 burning air, so the hanging wall around the top plate must be increased to fully ensure the opening area. However, when the top plate is thinned to improve the design, the hanging wall of the top plate must be reduced. Moreover, even if a vent is provided on the top plate, it is difficult to ensure a sufficient ventilation volume. 5 Also, it is known that in a stove with a grill in the stove body, exhaust gas from the grill can be exhausted from the vent of the top plate, but foreign objects can be dropped from the vent provided on the top plate, or ventilated The mouth is provided with a protective baffle to prevent foreign matter from falling, but it is not beautiful. Patent Document 1 10 Japanese Patent Application Laid-Open No. 11-22981 In order to solve the aforementioned problems, an object of the present invention is to provide a built-in stove capable of ensuring sufficient combustion air. Another object of the present invention is to provide a built-in stove which can prevent foreign matter from coming out of the air vent from falling when the oven is provided, and can perform exhaust smoothly. [Summary of the Invention] Means to Solve the Problem In order to achieve the foregoing object, the present invention provides an embedded stove, which is composed of a stove body that houses a gas burner and has an opening on the cover, and a cover 20 that covers the upper opening of the stove body. The top plate is formed, and the stove body is suspended from the opening provided on the workbench, which is characterized in that: a vent opening to the inside of the stove body is provided at the rear of the top plate, and at the front edge of the vent opening A shield is provided to block the air flow from the side of the stove through the vicinity above the vent. 6 1227770 In the present invention, since the vent is not provided on the hanging wall around the top plate but on the top of the top plate, it can be provided to form a large-area vent. However, the built-in stove is located almost in front of the kitchen wall, and the wind flows along the rear wall surface due to the combustion of the burner, so that the product flows from the front of the stove through the vent and backwards. In this state, the flow of wind is hindered by the flow of air passing near the upper part of the vent, and it is difficult to take in the combustion air from the vent. Therefore, in the present invention, since a mask is provided at the front edge of the vent to block the flow of air passing near the top of the vent, even if a wind flows from the front of the stove through the top of the vent and flows backwards The flow is not affected, and air can be sucked in from the vent to supply sufficient air to the stove body, so good combustion can be achieved. In addition, since the vent and the cover covering the vent are located at the rear of the top plate, the appearance when viewed from the front is not impaired. In addition, if the cover arrangement also covers the covering part above the vent, the effect of shielding the wind and preventing foreign matter from falling into the vent is also good. Therefore, if the mask is formed in an inclined shape rising from the front edge of the vent to the rear, the shape is also small. The present invention is also provided with an angle varying device capable of changing the inclination angle of the mask. Although the air flow is different according to the interval between the stove and the rear wall surface, and the suction state of the air from the vent is different, there may be cases where 20 sufficient air cannot be sucked. However, if the tilt angle of the mask can be changed, The angle of the mask can be adjusted in accordance with the distance from the rear wall surface, so that sufficient air can be sucked in. According to the present invention, the aforementioned top plate can be configured as a metal plate, such as an aluminum plate with a thickness of several mm, and an opening can be provided at the rear of the metal plate, and the 1227770 opening can be used as a vent. In addition, the vent can be set by cutting of the top plate, and a slot extending along the rear edge of the metal plate can be provided at a predetermined distance from the rear edge of the metal plate and folded through the slot. The folded sheet on the front side forms the aforementioned mask, thereby forming the aforementioned 5 vents and the aforementioned mask on the metal plate at the same time. At this time, specifically, a three-side notch is formed on the rear side of the top plate excluding the front side of the square, and a part of the top plate is folded through the notch. Alternatively, a side notch can also be formed on the rear side of the top plate. Fold the side up. Furthermore, 'the cover can be formed at the rear of the top plate by folding the back edge of the top plate, and the rear part of the stove body under the cover is opened to form 10 vents. At this time, it can also be fully folded at the rear portion of the top plate. It is also possible to leave both sides of the rear edge of the top plate and fold up the middle portion. In the present invention, when the top plate is configured as a thick metal plate, it is preferable that the mask has a thinner wall thickness than other parts, thereby making it possible to perform processing such as folding of the mask extremely easily. Further, a bending groove may be provided along a bending position when the mask 15 of the metal plate is folded, thereby making it possible to perform the folding and the like of the mask extremely easily. In the present invention, it is preferable to provide a member connecting the stove body and the top plate in the present invention, and the lower end portion of the connecting member is connected to the rear portion 7 of the stove body, and the upper end portion is difficult to form the connection formed by the fresh rear end. Qi Lian ,. In addition, in addition, the connection portion formed at the end edge behind the mask and the gas connection from the rear portion of the stove body to the gas-passing connection cannot be disconnected from the stove. Therefore, the above-mentioned top plate and the cooker can be firmly fixed because the connection member or the connection part can be hidden at the rear side of the cover and can be seen in the J-square position. Therefore, a good top plate appearance 1227770 can be maintained and the top plate and the cooker body can be connected. In addition, in the present invention, the above-mentioned top plate may also be constituted by a plate body and a metal frame-like frame body. In this case, the frame body preferably has a partition frame material for dividing the installation portion for installing the plate body and the air vent, Moreover, the partition frame material is integrally formed with the aforementioned cover 5 cover, thereby, an air vent and a cover can be provided in the frame body, and since the plate body does not need to be bent, a plate body such as glass or In addition, in the present invention, a connecting member connecting the stove body and the frame body is preferably provided, and a lower end portion of the connecting member is connected to the side of the rear portion 10 of the stove body, and an upper end portion is connected to the cover. under Or the rear is connected with the aforementioned frame. Accordingly, the upper end of the connecting member is hidden under or behind the cover, so it cannot be seen from the front of the stove, so it can maintain a good roof appearance and connect the roof to the stove body. In addition, in the present invention, a connecting portion may be formed after the end edge of the mask hangs down. 15 The connecting portion may be used when the rear edge of the top plate is folded to form a mask, or when a mask is formed on a part of the frame.

後端部40d水平地朝外側彎曲，且與前述前端部4〇b同時補 強長尺寸之遮罩40。 又，於傾斜部40a之兩側端形成側壁40c，且左右框材 37之水平緣部37b具有作為該側壁4〇c下端部之安置部之機 20能，而遮罩係配置於通氣口 33且可自由拆卸。另，如第3圖 所不’若於分隔框材38之垂直壁38a後方使後方緣部38c突 出為比遮罩40之板厚稍長，則具有作為遮罩40之前端部4〇b 安置部之機能，且可更安定地將遮罩40配置於通氣口 33。 另’該遮罩40係藉由彎曲加工而以鋁板一體形成傾斜部 13 1227770 40a、前端部條、兩側壁40c。 该遮罩40之傾斜部40a之傾斜係構成為可充分地取得 為遮罩4〇空氣吸入部之遮罩40之後端部40d與後側框材36 之上端間之間隔，一般宜為20度〜60度。若傾斜角度過小， 則然法充分取得空氣吸入部之間隔，若傾斜角度過大則外 觀變差。本例中係將傾斜部40a之傾斜角度設為25度而確保 後側框材36之垂直壁36a上端與後端部40d之間隔為14mm。 第3圖中，於燃燒器11之瓦斯燃燒時，嵌入式爐具10上 面空氣之流動因沿著後壁面4之上昇氣流而從爐具前部流 、、二通氣口 33上方而朝後方流動。故，僅大面積地將通氣口 33a又置於頂板3〇後部時，亦會受到因從爐具前方流經通氣 口 33上方附近之空氣流動之阻礙而使空氣不易從通氣口 ％ 之周圍流入通氣口 33，且燃燒用一次空氣不易吸入爐具本 體20内。 15 相對於此，若於通氣口 33設置遮罩40，則於遮罩40之 前面遮蔽了從爐具前部流經通氣口 33上方附近而朝後方流 動之空氣之流動，乃至於向上方流動而可加以防禦，於遮 罩40之背面則是空氣流經通氣口 33上方附近而朝後壁面4 流動者消失。故，由於不會受到空氣朝後壁面4流動之影響 20 而從通氣口 33吸引空氣，因此可從大面積之通氣口 33將充 分之空氣供給至爐具本體20内並進行良好之燃燒。另，遮 罩之形態亦可於通氣口 33之前緣設置為立壁狀，然而，特 別是若使遮罩40為具有覆蓋通氣口 33之覆蓋部之構造或兼 帶覆蓋部而從前緣朝後方上昇來傾斜，則在遮風效果及防 14 1227770 止異物掉入通氣口之效果上亦佳。 其次，參照第6圖說明本發明之第2實施形態。第6圖顯 示本發明第2實施形態之說明截面圖。 依照嵌入式爐具10與後方壁面4間之間隔而空氣之流 5 動不同，結果，來自通氣口 33之空氣吸入狀態不同而有無 法吸入充分之空氣之情形。故，本實施形態可調節遮罩42 之傾斜角度。遮罩42係由鋁板所構成，且藉由將彎曲形成 於遮罩42前部兩側之支持部42b轴支於設在左右框材37之 軸42a，而形成遮罩42之角度可變裝置。 10 依此，可藉由配合與後壁面4之間隔而調節遮罩42之角 度來吸入充分之空氣。另，第2實施形態中其他構造基本上 與參照第1至5圖所說明之第1實施形態相同。 其次，依據第7至11圖說明本發明之第3實施形態。第7 圖係顯示第3實施形態中頂板之平面圖，第8圖係顯示第7圖 15 之爐具後半部之說明截面圖，第9圖係顯示爐具本體與頂板 之連結構件之說明分解立體圖，第⑺及丨丨圖係顯示連結構 件之變形例之說明截面圖。 第3實施形態中遮罩45c係與頂框35A之分隔框材45為 一體。該遮罩45c係從分隔框材45之垂直壁45a上端朝後方 20向上方彎曲而傾斜。45b係從垂直壁45a下端水平地朝前方 突出之緣部。46係支持板，且設置於遮罩45c兩端部附近與 中央部3處。支持板46係藉由鉚釘46b(第7及9圖所示)使下端 之琴曲部46a與後框材36之水平緣部36b連結。頂框35A之構 造與第4圖之頂框35間除了其分隔框材38之外其他相同。 15 1227770 另，由於分隔框材45與遮罩45c為一體，因此分隔框材45最 後安裝於兩側框材37。又，於第7圖中雖然省略圖式，不過， 如第8及9圖所示，頂框35A與本體20係藉由連結構件2〇al 來連結。 5 連結構件20al係連結於支持板46後緣一側突出形成之 舌片46c與本體20之底部。即，水平設置於連結構件汕“下 ^之下部連結部20a2螺接於本體2〇之底部，且立起設置於 連結構件20al上端之上部連結部2〇a3透過螺釘11而螺接於 支持板46之舌片46c。藉此，由於連結構件2〇al之上部連結 1〇部20a3與支持板46之舌片46c間之連結部分隱藏於遮罩45c 而無法從爐具前方看見，故不會損害頂板之外觀，且由於 支持板46之舌片46c後方露出螺釘η，因此遮罩45c不會成為 阻礙而可輕易地進行連結作業。 又，於第3實施形態中，由於藉由遮罩45(：使後框材36 15位於無法從前方看見之位置，故，如第10圖所示，可藉由 螺釘η連結連結構件20bl之上部連結部2〇b2與後框材36。再 者，除此之外，如第11圖所示，亦可於後框材36之水平緣 部36b設置連結板36f，且藉由螺釘n連結該連結板36f與連結 構件20cl之上部連結部20c2。連結板36f之螺釘固定部36g 20係朝遮罩45(：後部侧之開放方向傾斜而形成，且連結構件 20cl之上部連結部20c2係形成為對應連結板36f之螺釘固定 部36g而抵接於其裏面之形狀。藉此，連結構件2〇ci之上部 連結部20c2與連結板36f之螺釘固定部36g間之連結部分藉 由遮罩45c而隱藏，且無法從爐具10之前方看見而無損於頂 16 1227770 :之1卜:二由於可從遮罩45禮方進行螺釘η之螺接作 業’ 口 ‘罩5C不會成為阻礙而可輕易地進行於遮罩45c 下方之連結作業。 Hue 另’於本例中，後框材36與左右框材37係將L形零件47 鉚釘固定於該等框材之水平緣部灿、·間當然，亦可 與第i實施形態相同，以藉由該等框材前端部之凹凸之敛人 來安裝。 ϋ 又，第3實施形態中’由於一體形成遮罩祝與分隔框 材45，因此遮罩45c之製作可較為省力。 10 前述第1至第3實施形態中皆針對具有内焰式瓦斯燃燒 器11之嵌入式爐具來作說明，然而，瓦斯燃燒器亦可為外 焰式瓦斯燃燒器。又，板體亦可採用金屬板，例如板厚數 mm之鋁板以取代玻璃板。 其次，依據第12至14圖說明本發明之第4實施形熊。第 15 12圖係顯示本發明嵌入式爐具之第4實施形態之立體圖，第 13圖係拆掉第12圖爐具遮罩之立體圖，第14(a)圖係顯示第 12圖之爐具後半部之說明截面圖，第14(b)圖係第12圖之爐 具中遮罩之一部分之立體圖。 苐4實施形態之欲入式爐具1 〇係金屬板之艇頂面爐 2〇 具，且覆蓋爐具本體20上面之頂板50係由一片板厚數爪爪之 鋁板所構成。該頂板50之後部設有與第1至5圖所示之第1實 施形態相同之罩式遮罩60，且覆蓋設置在頂板50後部之通 氣口63上方。第4實施形態中，如第13圖所示，通氣口 63係 從頂板50之後邊起留下15mm之後緣而藉由切削加工形 17 1227770 成。於玻璃板留下窄幅之後緣而形成開口是困難的，但若 為板厚數mm之鋁板，則具有同時擁有與玻璃板相同之厚重 感與可輕㈣進行形成開π之加卫之優點以及不需要頂框 之優點。 5 如第12及13圖所示，於頂板5〇在前後方向大略中央位 置與其間靠後方之位置3處設有窗孔A且具妹納於爐具 本體20内之大燃燒|§ 5 la與其内側之小燃燒器5lb之母子型 外焰式瓦斯燃燒器51係面對該左右窗孔52且朝上方露出， 而外焰式中瓦斯燃燒器53則面對靠後方之窗孔52且朝上方 1〇露出。於各燃燒器51、51、53之周圍，火架12係分別載置 於頂板50。又，於頂板50靠前方之中央部位置分別設有用 以進行該等瓦斯燃燒器51、51、53之點火、火力調整及熄 火操作之點火鈕13。 爐具本體20係與第1實施形態相同地吊持於工作台2之 15開口3。頂板5〇係於自爐具本體20之凸緣22朝外側延伸之頂 板50周緣部下面固定有墊料54，且透過該墊料54於工作台2 之上面著地。第14(a)圖中標號17為點火栓。 遮罩60係形成為鋁製遮罩，且該鋁製遮罩係由從通氣 口 63前緣部朝後方向上方傾斜之傾斜部6〇a、前端部6(^、 20後端部6〇d與兩側壁部60c所構成。遮罩6〇係將作為前端部 6〇b之卡止部之階部60bl卡止於頂板50之通氣口63前緣 63a，且將作為兩側壁部60c之卡止部之階部6〇e卡止於通氣 口 63後緣63b而設置於通氣口 63。 另，如第14(b)圖所示，若將於前端部、後端部具有卡 1227770 止部60el、60e2之腳部60cl設置於兩側壁部6以，則可保持 遮罩60之傾斜角度，同時可將遮罩60卡止於通氣口 63之口 緣。 由於本實施形態之頂板50亦於頂板後部設置通氣口 5 63，因此可設置大面積之通氣口63，且由於更在通氣口 63 没置遮罩60(特別是朝向後方上昇方向傾斜之遮罩），因此不 會受到於燃燒！51(51a、51)之瓦斯燃燒時朝後壁面4流動之 空氣之影響，且可從通氣口63吸入空氣而可從大面積之通 氣口將充分之空氣供給至爐具本體2〇内並實現良好之燃 1〇燒。又，由於通氣口 63及覆蓋該通氣口 63之遮罩60位於頂 板50後部’因此不會損害從前方看爐具10時之外觀。 第15圖係顯示本發明第5實施形態之截面圖，本實施形 悲係藉由設置角度可變裝置而可調節遮罩65之傾斜角度， 其構造係’朝遮罩65之前部兩側端彎曲而形成支持部65a， 15且將設置在L字形之各支持板55之軸55a插入支持部65a之 孔’而支持板55係安裝於由金屬板之鋁板所構成之頂板5〇 之通氣口 63前側端面者。 若藉由第5實施形態，則可與第2實施形態相同地依照 空氣流動之不同來調節遮罩65之角度，藉此可吸入充分之 20 空氣。 如第16(a)及16(b)圖所示，本發明之第6實施形態係， 於與作為金屬板之铭板所構成之頂板5〇後端緣間隔預定距 離之位置設置沿著該金屬板後端緣延伸之切槽，且具有藉 由透過該切槽折起前方側之折起片所形成之遮罩66與通氣 1227770 口 63。即，於頂板5〇在扣除長方形前側之長邊之3邊設置切 口 56a(切槽），且將以該3邊切口 56a所包圍之長方形片56b 立成傾斜姿態而形成通氣口 63，同時將折起之長方形片 56b(折起片）作為遮罩66。另，亦可使片56b立起而作為立 5壁，不過，如圖所示，藉由使其傾斜，可得到防止異物掉 落之效果，依此，可僅藉由頂板之加工而形成遮罩66，且 可減少零件數。 另，前述例中係於3邊設置切口並切割立起而形成遮罩 66，其變形例係如第16(c)圖所示，亦可於頂板50之後部側 10設置1邊切口，並藉由切割拉起而使遮罩66與通氣口 63成 形。 又’第ό實施形態中，如第16⑻圖所示，可透過遮罩66 而藉由連結構件20dl連結頂板5〇與爐具本體2〇。此時，藉 由點熔接等方法，將藉由彎曲為L字形之金屬板之連結部 15 66a固定設置於遮罩66之下面側，並藉由螺釘n使連結構件 20dl之上端連結部20d2連結於此。 又，除此之外，如第17(a)及17(b)圖所示，亦可使遮罩 66之後端緣朝下方彎曲而形成連結部66b，且於該連結部 66b之預定位置設置螺紋孔66c，並將連結構件20el之上端 20 連結部2〇e2螺釘固定於該連結部66b。 又，未使用連結構件20el時，如第18(a)及18(b)圖所 示，亦可切割立起爐具本體20之凸緣22之一部分而形成被 連結部22c，且將遮罩66後端緣之連結部以^螺釘固定於此。 前述參照第1至16圖所說明之嵌入式爐具1()皆於頂板 20 1227770 30 ? 50之後部設置長孔狀通氣口 33、63，然而，通氣口亦 可為不留下頂板後緣而將頂板後緣切割為長方形之開口。 第19至20圖所示之第7實施形態係全面地折起由金屬 板之鋁板所構成之頂板50後邊，且於頂板後部形成後部側 5 上昇之傾斜狀態之遮罩68，並於遮罩68下方於與爐具本體 20之凸緣22間形成通氣口 63A。此時，頂板50之後部係由於 頂板未接觸工作台2之上面，因此，介於爐具本體20之凸緣 22與工作台2之間於全周插入本體墊料58。又，介於頂板50 之遮罩68以外之部分與工作台2間插入之頂面板墊料54係 10 作成厚度為可放入本體墊料58者。 又，第19(c)圖顯示折起頂板後緣而於與爐具本體20之 凸緣22間形成通氣口 63A之其他例子。該例係留下頂板50A 之後緣兩側部50B而折起中間部來形成遮罩70。 又，第7實施形態中，如第19(b)圖所示，可透過遮罩68 15 而藉由連結構件20fl連結頂板50與爐具本體20。即，藉由 點溶接等方法，將藉由彎曲為L字形之金屬板之連結部68b 固定設置於遮罩68之下面側，並藉由螺釘n使連結構件2〇fl 之上端連結部20f2連結於此。 又’除此之外，如第21(a)及21(b)圖所示，亦可使遮罩 20 68之後端緣朝下方彎曲且一部分更向下方延伸而形成連結 部68a ’且於該連結部68a設置螺紋孔68b，並將連結構件 20gl之上部連結部2〇g2螺釘固定於該連結部68a。 又，未使用連結構件20gl時，如第18(a)圖所示，亦可 立起爐具本體20之凸緣22之一部分而形成被連結部22c，且 21 1227770 將遮罩68後端緣之連結部68a螺釘固定於此。 另，第6及第7實施形態中，折起頂板5〇之後緣時，例 如，如第22(a)圖所示，藉由使折起之部分，即，形成遮罩 68之部分具有較其他部分薄之壁厚，可輕易地進行頂板兄 5之彎曲加工。又，例如，如第22(b)圖所示，若藉由沿著折 起頂板50時之彎曲位置形成彎折溝68c，則亦可輕易地進行 頂板50之彎曲加工。 前述第4至第7實施形態皆針對具有外焰式瓦斯燃燒器 51之嵌入式爐具作說明，然而瓦斯燃燒器亦可為内焰式瓦 10斯燃燒裔。另，金屬板亦可為其他金屬，例如可構成為sus 板，但由於鋁板較輕，因此藉由構成為板厚數瓜瓜之板之頂 板而可作成具有與玻璃相同重量感之頂板。 又，各實施形態中所說明之頂板與爐具本體間之連結 構造並不僅在各自之實施形態中採用，亦可依照頂板之尺 15寸或爐具本體之尺寸而選擇任一者之連結構造。 又，於此種爐具中，如第23圖所示，爐具本體2〇之前 面20z於工作台2下方朝使用者側露出，且於該露出之前面 20z形成内裝在爐具本體2〇之烤爐67之前面開口 ，同時 構成為烤架窗68開關該前面開口 67z。另，頂版30係與第3 20貝施形怨之第8圖所示之頂板30相同。 依此，於爐具本體20内部具有烤爐67者可將通氣口 33 作為排。g卩’由於具有烤爐67則可進行來自前面側(前 面開口67’之燃燒用—次空氣之取人，因此透過通氣口 33可將來自烤爐67之排氣排出至外部。此時，通氣口 33之 22 1227770 上部係藉由一體設置於分隔框材且從垂直壁45a上端朝後 方向上方彎曲而傾斜之遮罩45c來覆蓋，因此可防止異物從 通氣口 33掉入爐具本體20之内部。另，於第23圖中雖未圖 示連結頂板30與爐具本體20之連結機構，不過可採用前述 5 頂板之連結機構。 【圖式簡單說明3 第1圖係顯示本發明嵌入式爐具之第1實施形態立體 圖。 第2圖係拆掉第1圖爐具遮罩之立體圖。 10 第3圖係第1圖爐具之一部分之說明截面圖。 第4圖係顯示覆蓋第1圖爐具本體之上面之玻璃頂板框 體之平面圖。 第5圖係顯示第1圖之爐具本體内之燃燒器等之配置概 要平面圖。 15 第6圖係顯示本發明嵌入式爐具之第2實施形態之主要 部分說明截面圖。 第7圖係顯示本發明嵌入式爐具之第3實施形態中頂板 之平面圖。 第8圖係顯示第7圖之爐具後半部之說明截面圖。 20 第9圖係顯示爐具本體與頂板之連結構件之說明分解 立體圖。 第10圖係顯示連結構件之變形例之說明截面圖。 第11圖係顯示連結構件之其他變形例之說明截面圖。 第12圖係顯示本發明嵌入式爐具之第4實施形態之立 23 1227770 體圖。 第13圖係拆掉第12圖爐具遮罩之立體圖。 第14(a)圖係顯示第12圖之爐具後半部之說明截面圖， 第14(b)圖係第12圖之爐具中遮罩之一部分之立體圖。 5 第15圖係顯示本發明嵌入式爐具之第5實施形態中爐 具後半部之說明截面圖。 第16(a)圖係顯示本發明嵌入式爐具之第6實施形態立 體圖，第16(b)圖係第6實施形態中爐具後半部之說明截面 圖，第16(c)圖係顯示第6實施形態中遮罩之變形例之立體 10 圖。 第17(a)圖係顯示第6實施形態中遮罩之其他變形例之 立體圖，第17(b)圖係顯示第6實施形態中頂板與本體間之其 他連結構造之爐具後半部之說明截面圖。 第18(a)圖係顯示第6實施形態中爐具本體之其他變形 15 例之立體圖，第18(b)圖係顯示第6實施形態中頂板與本體間 之其他連結構造之爐具後半部之說明截面圖。 第19(a)圖係顯示本發明嵌入式爐具之第7實施形態立 體圖，第19(b)圖係第7實施形態中爐具後半部之說明截面 圖，第19(c)圖係顯示第7實施形態中遮罩之變形例之立體 20 圖。 第20圖係顯示第19圖之爐具頂板之平面圖。 第21(a)圖係顯示第7實施形態中遮罩之其他變形例之 立體圖，第21(b)圖係顯示第7實施形態中頂板與本體間之其 他連結構造之爐具後半部之說明截面圖。 24 l22777〇 第22(a)圖係顯示第7實施形態中頂板之變形例之部分 側視圖，第22(b)圖係顯示第7實施形態中頂板之其他變形例 之部分側視圖。 第23圖係顯示具有烤爐之嵌入式爐具之說明截面圖。 【圓式之主要元件代表符號表】 2···工作台 20a3，20b2，20c2，20g2···上 3···開口 部連結部 4···後壁面 20d2，20e2···上端連結部 1〇··.嵌入式爐具 20ζ· · ·前面 11，51，53…瓦斯燃燒器 21…周壁 12···火架 21a···突起 13...點火姐 22…凸緣 14…旋塞 22a···塾料 14a...操作軸 22b…螺接突起 15…歧管 22c···被連結部 15a···瓦斯配管 30…頂板 15b···入口 31···玻璃板 16...熱電偶 32 ’ 52···窗孔 16a...導線 33，63···通氣口 17...點火栓 33a···前緣部 20...爐具本體 35…頂框(框體） 20al，20bl，20cl，20dl，20el， 36 ’ 37，38···框材 20fl，20gl…連結構件 36a ’ 37a ’ 38a，45a...垂直壁 20a2···下部連結部 36b，37b，38b，38c，45b···緣 25 1227770 部 36bl，38bl··.頭部 36c，37c…凸緣部 36d，66c，68b···螺紋孔 36e...螺釘 36f...連結板 36g...螺釘固定部 37bl，37b2·.·凹部 38…分隔框材 39.. .矽煉焦材 40，42，45c，60，65，66，68··· 遮罩 40a，60a···傾斜部 40b，60b...前端部 40c...側壁 40d，60d…後端部 42b，65a···支持部 42a，55a··.車由 45.. .分隔框材 46，55...支持板 46a··.彎曲部 46b...鉚釘 46c...舌片 47.. 丄形零件 50…板體 50B...兩側部 54.. .頂面板墊料 56a···切口（切槽） 56b...片 58…本體墊料 60bl，60e···階部 60c...兩側壁部 60cl...腳部 60el，60e2··.卡止部 63a...前緣 63b...後緣 66a，66b，68a，68b.··連結部 67…烤爐 67z···前面開口 68.. .烤架窗 68c.··彎折溝 η...螺釘 26The rear end portion 40d is horizontally curved outward, and at the same time as the front end portion 40b, the long-sized mask 40 is reinforced. In addition, side walls 40c are formed on both side ends of the inclined portion 40a, and the horizontal edge portions 37b of the left and right frame members 37 have a function as a placement portion of the lower end portion of the side wall 40c, and the cover is disposed on the vent 33 And it can be disassembled freely. In addition, as shown in FIG. 3, if the rear edge portion 38c protrudes behind the vertical wall 38a of the partition frame 38 to be slightly longer than the thickness of the cover 40, it is provided as the front end portion 40b of the cover 40. It is possible to arrange the cover 40 on the ventilation port 33 more stably. The mask 40 is formed by integrally forming an inclined portion 13 1227770 40a, a front end strip, and both side walls 40c by an aluminum plate by bending. The inclination of the inclined portion 40a of the cover 40 is such that the distance between the rear end portion 40d of the cover 40 serving as the cover 40 air intake portion and the upper end of the rear side frame member 36 can be sufficiently obtained, and is generally preferably 20 degrees. ~ 60 degrees. If the inclination angle is too small, then the interval of the air suction part is sufficiently obtained, and if the inclination angle is too large, the appearance becomes worse. In this example, the inclination angle of the inclined portion 40a is set to 25 degrees, and the distance between the upper end of the vertical wall 36a of the rear side frame material 36 and the rear end portion 40d is 14 mm. In Figure 3, during the gas combustion of the burner 11, the air flow on the built-in stove 10 flows from the front of the stove due to the updraft along the rear wall surface 4, above the second vent 33 and flows backward. . Therefore, when the ventilation port 33a is placed on the rear of the top plate 30 only in a large area, it will be hindered by the air flowing from the front of the stove through the vicinity of the ventilation port 33, so that the air will not easily flow in from around the ventilation port%. The ventilation port 33 is difficult for the primary air for combustion to be sucked into the stove body 20. 15 In contrast, if a cover 40 is provided in the vent 33, the front of the cover 40 blocks the flow of air flowing from the front of the stove through the vicinity of the vent 33 and backward, or even upwards. On the other hand, it can be protected. On the back of the cover 40, air flows through the vicinity of the upper part of the vent 33 and disappears toward the rear wall 4. Therefore, since the air is not attracted from the air vent 33 by the influence 20 of the air flowing toward the rear wall surface 4, it is possible to supply sufficient air from the large air vent 33 to the stove body 20 and perform good combustion. In addition, the shape of the mask may be provided in a vertical wall shape at the leading edge of the vent 33. However, in particular, if the mask 40 has a structure that covers the vent 33 or has a covering portion, the mask 40 rises from the front edge to the rear. To tilt, it is also good in the effect of shielding the wind and preventing 14 1227770 from falling into the vent. Next, a second embodiment of the present invention will be described with reference to Fig. 6. Fig. 6 is an explanatory sectional view showing a second embodiment of the present invention. Depending on the interval between the built-in stove 10 and the rear wall surface 4, the air flow 5 varies, and as a result, the air suction state from the vent 33 is different, and there may be cases where sufficient air cannot be sucked. Therefore, in this embodiment, the inclination angle of the mask 42 can be adjusted. The cover 42 is made of an aluminum plate, and the support 42b bent and formed on both sides of the front portion of the cover 42 is pivotally supported on the shaft 42a provided on the left and right frame members 37 to form a variable angle device of the cover 42 . 10 According to this, the angle of the mask 42 can be adjusted by matching the interval with the rear wall surface 4 to suck in sufficient air. The other structures in the second embodiment are basically the same as those of the first embodiment described with reference to Figs. Next, a third embodiment of the present invention will be described with reference to Figs. 7 to 11.
