Description

【0001】
【発明の属する技術分野】
本発明はガスコンロ等に用いられ、魚等の被調理物を加熱調理するグリルに関する。
【0002】
【従来の技術】
この種のグリルは例えばガスコンロの中央部に一体的に組み込まれ、焼き網に載置された魚等の被調理物を加熱調理するのに使用される。ガスコンロの天板の排気口に連通する排気筒を備えたグリル庫には、庫内で被調理物を支持する焼き網の上方に加熱装置であるグリルバーナーが設けられ、また、グリル庫の底部には被調理物を加熱調理した場合に生じる脂、水等の焼汁を収容するための平坦な底板形状のグリル皿が焼き網の下方に位置して収納される。
【0003】
ところで、グリル調理時に、例えば調理者がグリルでの調理を忘れた場合のように被調理物を加熱調理状態のまま放置すると、該被調理物から多量の油煙が発生する。この場合、該油煙がグリルバーナーの燃焼面に直接接触すると、該グリルバーナーの炎が油煙に引火し、被調理物の表面に露出した脂やグリル皿に収容された焼汁の油分の発火が誘発され、グリル庫内部が異常に過熱されるおそれがある。
【0004】
この場合、グリル皿に収容された焼汁の発火は、グリル皿を例えば庫内ドラフト作用でグリル庫内に吸込まれる空気により冷却することで防止できる。他方で、上記油煙の引火や被調理物自体の発火を防止するのは容易ではない。
【0005】
このような問題に鑑み、例えば特開平11ー47000号公報では、グリルバーナーを全一次空気式のバーナーで構成すると共に焼き網より上方であって、グリル庫の側壁に配置し、また、グリル庫から排気筒へと連通する部分を焼き網の下方に設定してグリルを構成している。このものは、たとえ被調理物を加熱調理状態のまま放置したとしても、焼き網の被調理物載置面の領域を酸欠状態にすることで被調理物の発火を防止するものであるが、輻射加熱を利用するものではなく主として対流加熱により被調理物を加熱調理するため被調理物がこんがりと焼けず(焼き性能が低下する)、被調理物の風味が落ちる。
【0006】
他方で、輻射加熱を利用したグリルにおける異常過熱防止手段は例えば特願平11ー356333号明細書に記載されている。これは、グリル庫に連結された排気筒の内面にサーミスタ素子からなる温度センサーを設けて庫内温度を常時監視することでグリル庫の異常過熱を検出するように構成したものである。そして、該温度センサーの検出温度が所定の温度に到達すると燃料ガスの供給を停止してグリルバーナーの火炎を自動消火する。
【0007】
【発明が解決しようとする課題】
しかしながら、このものでは、グリル庫内部の異常過熱を検出するため温度センサーやその制御手段、並びにグリルバーナーの火炎を自動消火した場合に調理者に対してその消火を知らせる報知手段等をグリルに装備する必要があるのでコスト高になると共にグリルの構造も複雑になる。
【0008】
そこで、本発明は、上記問題点に鑑み、誤って調理者が被調理物を加熱調理状態のまま放置したとしても、簡単な構造で被調理物から出る油煙を加熱装置の加熱面に直接接触しないようにし、その油煙の引火を防止することでグリル庫内部の異常過熱が防止できるグリルを提供することを課題とする。
【0009】
【課題を解決するための手段】
この課題を解決するために本発明は、グリル庫の天井部にグリルバーナーを備えると共に該グリル庫の後側に燃焼排気等をグリル庫の外部に排出する排気筒を連結し、該グリルバーナーの下方に位置するグリル皿に支持される焼き網に載置された被調理物を加熱調理するグリルにおいて、前記グリル庫の底板に、グリル庫内に空気を吸込む空気孔を設けると共に、前記グリルバーナーの後部と前記排気筒の前部との間に、グリルバーナーの燃焼排気を下方に偏向させると共に焼き網に載置された被調理物からの油煙がグリルバーナーの加熱面に接触しないようにする仕切板であって、その下端が焼き網の被調理物載置面より上方に位置する仕切板を設け、前記空気孔から吸込まれて前記グリル皿に衝突し、該グリル更に沿ってグリル庫後方に流れる空気と、前記仕切板によって下方に偏向された燃焼排気とが、仕切板の下端付近で合流するように構成されていることを特徴とする。
【0010】
グリル調理時に、被調理物を加熱調理状態のまま放置すると、該被調理物から多量の油煙が発生する。そして、該油煙がグリルバーナーの燃焼面に直接接触すると、該グリルバーナーの炎が油煙に引火し、ひいては、グリル庫内部が異常に過熱されるおそれがある。そこで、本発明では、通常排気筒へ直接流れる燃焼排気を下方に偏向させるように加熱装置の後部と排気筒の前部との間に仕切板を設けた。これにより、グリル調理時に被調理物を加熱調理状態のまま放置することで被調理物から多量の油煙が発生したとしても、上方に向かう油煙が、下方に偏向された燃焼排気と相俟って庫内ドラフト作用で仕切板の下側を水平に流れて直ちに排気筒に案内される。その結果、該油煙が加熱装置の加熱面に直接接触することがないため引火することが防止できる。また、油煙の引火を防止することでグリル庫内の温度が上昇するのが防止され、被調理物の表面に露出した脂やグリル皿に収容された焼汁の油分の発火が誘発されず、グリル庫内部の異常過熱が防止できる。さらに、本発明では、燃焼排気を下方に偏向する仕切板を設けた構造であるため、特別の制御手段等を必要せずグリルの構造を簡単にでき、コストの低減を図ることもできる。
【0011】
【発明の実施の形態】
図1及び図2を参照して、ガスコンロ1は天板11の開口部に臨ませて設けた2個のコンロバーナー12を備え、該コンロバーナー12の作動は両端の正面パネル13に取付けられた操作ボタン14や火力調節レバー15により制御される。魚等の被調理物を調理するグリル2は、ガスコンロ1の中央部に、即ち、両端の正面パネル13の間に位置して一体的に組み込まれる。
【0012】
グリル2は略直方体形状であってスチール製のグリル庫21を備えている。グリル庫21の後側にはガスコンロ1の天板11に設けた排気口16に連通する排気筒22が設けられている。該グリル庫21の開口した前面には耐熱性ガラスが嵌め込まれたグリル扉23が着脱自在に装着される。該グリル扉23は、該グリル扉に着脱自在な枠材23aを備え、該枠材23aが後述のグリル皿24を支持してグリル扉2の開閉に伴ってグリル皿24をグリル庫から出し入れする役割を果たす。
【0013】
グリル皿24は、薄板を略長方形の皿状でかつその周囲に略水平なつば部が形成されるようにプレス成形した後、フッ素樹脂等の仕上塗装を施したものである。グリル皿24の底板の四隅には、焼き網25が載置される焼き網支持部24aが形成されている。グリル庫内で魚等の被調理物を保持する焼き網25の前後の端部には網面に対して直角に延びる支持部材25aを備える。そして、グリル2での調理開始前に、支持部材25aを焼き網支持部24aに載置することで焼き網25がグリル皿24と共にグリル庫21に収納される。
【0014】
ところで、本発明の実施形態のグリル2では使用に際してグリル皿24に水を入れずに使用できる。本実施の形態では、グリル庫21の底板のほぼ中央部に略長方形でかつグリル庫の下方向に見て凸状の突出部21aが一体的に形成されている。該突出部21aの面積はグリル皿24の底板の面積より小さく形成されている。また、突出部21aの平坦部には複数個の隆起部21bが形成され、その頂部には空気孔21cが開設されている。該隆起部21bの高さは、例えば調理者がグリル皿24をグリル庫21から出し入れする際にグリル皿24と接触しない範囲であれば定寸自在である。これにより、グリル調理時の庫内ドラフト作用により誘引される上昇気流によって、突出部21aの平坦部に形成した隆起部21bの各空気孔21cから空気が吸込まれる。この場合、空気はグリル皿24に垂直な方向から吸込まれて直接グリル皿24の底面に衝突するためグリル皿24が十分かつ均等に冷却される。また、グリル庫21の天井部には、焼き網に載置された被調理物を輻射加熱するグリルバーナー26が取付けられている。
【0015】
該グリルバーナー26は、貫通する複数個のガス噴出口を備えた複数枚のセラミック製プレートを装着してなるシュバンク式バーナーで構成され、該グリルバーナーの作動が正面パネル13に取付けられた操作ボタン14aや火力調節レバー15bにより制御される。
【0016】
ところで、グリル2での調理時に、例えば調理者がグリル2での調理を忘れた場合のように被調理物を加熱調理状態のまま放置すると、該被調理物から多量の油煙が発生する。この場合、所定量以上の油煙が発生し、グリルバーナー26の燃焼面に直接接触するとグリルバーナー26の炎がその油煙に引火し、被調理物の表面に露出した脂やグリル皿24に収容された焼汁の油分の発火が誘発され、グリル庫内部が異常に過熱されるおそれがある。この場合、排気筒22の内面に温度センサーを設けて庫内温度を常時監視することもできるが、これではコスト高になる。そこで、本実施の形態では、グリルバーナー26の後部と排気筒22の前部との間に、グリルバーナー26の燃焼排気を下方に偏向させると共に焼き網25に載置された被調理物からの油煙がグリルバーナー26の燃焼面に接触しないようにする仕切板27をグリル庫21の天井部から吊設した。
【0017】
図3を参照して、該仕切板27はステンレス等の耐熱性材料から形成され、グリル庫21の横幅に対応する横幅を有すると共に、仕切板27の下端が焼き網の被調理物載置面より上方に位置している。そして、このような仕切板27を設けることでグリルバーナー26からの燃焼排気流が下方に偏向される。これにより、グリル調理時に被調理物を加熱調理状態のまま放置することで被調理物から多量の油煙が発生したとしても、上方に向かう油煙が、下方に偏向された燃焼排気と相俟って庫内ドラフト作用で仕切板27の下側を水平に流れて直ちに排気筒22に案内される。このため、該油煙がグリルバーナー26の燃焼面に直接接触することがないため、該グリルバーナー26の炎がその油煙に引火することが防止できる。また、油煙の引火を防止することでグリル庫21内部の温度が急上昇するのが防止され、被調理物の表面に露出した脂やグリル皿24に収容された焼汁の油分の発火が誘発されず、グリル庫内部の異常過熱が防止できる。

BACKGROUND OF THE INVENTION
The present invention relates to a grill that is used in a gas stove or the like and cooks a food such as fish.
[0002]
[Prior art]
This type of grill is integrated in a central portion of a gas stove, for example, and is used for cooking food to be cooked such as fish placed on a grill. A grill cabinet provided with an exhaust pipe communicating with an exhaust port of a top plate of a gas stove is provided with a grill burner as a heating device above a grill net that supports an object to be cooked in the cabinet, and the bottom of the grill cabinet A flat bottom plate-shaped grill pan for storing grilled juice such as fat, water, etc. generated when the object to be cooked is cooked is positioned below the grill net.
[0003]
By the way, at the time of grill cooking, if the cooked food is left in the cooking state as if the cook forgot to cook on the grill, for example, a large amount of oily smoke is generated from the cooked food. In this case, when the oil smoke comes into direct contact with the combustion surface of the grill burner, the flame of the grill burner ignites the oil smoke, and the ignition of the oil exposed to the fat exposed on the surface of the object to be cooked or the oil of the broth contained in the grill pan. There is a risk that the inside of the grill will be abnormally overheated.
[0004]
In this case, the firing of the broth contained in the grill pan can be prevented by cooling the grill pan with, for example, air sucked into the grill pan by an internal draft operation. On the other hand, it is not easy to prevent the ignition of the above-described oil smoke and the ignition of the cooking object itself.
[0005]
In view of such a problem, for example, in Japanese Patent Application Laid-Open No. 11-47000, the grill burner is constituted by an all-primary air type burner, and is disposed above the grill net and on the side wall of the grill cabinet. A grill is configured by setting a portion communicating with the exhaust pipe from the bottom of the grill. This is to prevent the cooking object from igniting by making the region of the cooking object placing surface of the grill net deficient even if the cooking object is left in the cooking state. In addition, since the food to be cooked is cooked mainly by convection heating rather than using radiant heating, the food to be cooked does not burn and the baking performance deteriorates, and the flavor of the food to be cooked falls.
[0006]
On the other hand, a means for preventing abnormal overheating in a grill using radiant heating is described, for example, in Japanese Patent Application No. 11-356333. In this configuration, a temperature sensor composed of a thermistor element is provided on the inner surface of the exhaust pipe connected to the grill cabinet, and the temperature inside the cabinet is constantly monitored to detect abnormal overheating of the grill cabinet. When the temperature detected by the temperature sensor reaches a predetermined temperature, the supply of the fuel gas is stopped and the flame of the grill burner is automatically extinguished.
[0007]
[Problems to be solved by the invention]
However, in this case, the grill is equipped with a temperature sensor and its control means for detecting abnormal overheating inside the grill cabinet, and a notification means for notifying the cook when the grill burner flame is automatically extinguished. This increases the cost and the structure of the grill.
[0008]
Therefore, in view of the above-described problems, the present invention directly touches the heating surface of the heating device with the oil smoke coming out of the cooked food with a simple structure even if the cook accidentally left the cooked food in the heated cooking state. It is an object of the present invention to provide a grill that can prevent abnormal overheating inside the grill cabinet by preventing the oil smoke from igniting.
[0009]
[Means for Solving the Problems]
In order to solve this problem, the present invention is provided with a grill burner at the ceiling of the grill cabinet, and an exhaust pipe for discharging combustion exhaust gas or the like to the outside of the grill cabinet is connected to the rear side of the grill cabinet. A grill for heating and cooking an object to be cooked placed on a grill supported by a grill pan positioned below, wherein a bottom plate of the grill cabinet is provided with air holes for sucking air into the grill cabinet, and the grill burner Between the rear part and the front part of the exhaust pipe, the combustion exhaust of the grill burner is deflected downward and the smoke from the food to be cooked placed on the grill net does not contact the heating surface of the grill burner. A partition plate, the lower end of which is located above the cooking object mounting surface of the grill net, is provided through the air hole and collides with the grill pan, and further along the grill along the rear side of the grill cabinet In And air, a combustion exhaust gas is deflected downward by the partition plate, characterized in that it is configured to merge in the vicinity of the lower end of the partition plate.
[0010]
If the cooking object is left in the cooking state during grill cooking, a large amount of oily smoke is generated from the cooking object. When the oil smoke comes into direct contact with the combustion surface of the grill burner, the flame of the grill burner ignites the oil smoke, and as a result, the inside of the grill cabinet may be abnormally overheated. Therefore, in the present invention, a partition plate is provided between the rear part of the heating device and the front part of the exhaust pipe so as to deflect downward the combustion exhaust gas that normally flows directly to the exhaust pipe. As a result, even if a large amount of oil smoke is generated from the cooking object by leaving the cooking object in the cooking state during grill cooking, the upward oil smoke is combined with the combustion exhaust deflected downward. It flows horizontally under the partition plate by the draft operation in the cabinet and is immediately guided to the exhaust pipe. As a result, since the oil smoke does not directly contact the heating surface of the heating device, it is possible to prevent ignition. Also, by preventing the ignition of oil smoke, the temperature inside the grill is prevented from rising, and the ignition of the oil exposed to the fat exposed on the surface of the cooking object or the cooking oil contained in the grill pan is not induced, Abnormal overheating inside the grill can be prevented. Furthermore, in the present invention, since the partition plate for deflecting the combustion exhaust downward is provided, the grill structure can be simplified and the cost can be reduced without requiring any special control means.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
With reference to FIG.1 and FIG.2, the gas stove 1 is provided with the two stove burners 12 provided facing the opening part of the top plate 11, and the operation | movement of this stove burner 12 was attached to the front panel 13 of both ends. It is controlled by the operation button 14 or the heating power adjustment lever 15. The grill 2 for cooking an object to be cooked such as fish is integrated in the central portion of the gas stove 1, that is, between the front panels 13 at both ends.
[0012]
The grill 2 has a substantially rectangular parallelepiped shape and includes a steel grill cabinet 21. An exhaust cylinder 22 communicating with the exhaust port 16 provided on the top plate 11 of the gas stove 1 is provided on the rear side of the grill cabinet 21. A grill door 23 in which heat-resistant glass is fitted is detachably mounted on the front surface of the grill cabinet 21. The grill door 23 is out with a freely frame member 23a removably attached to the grill door, a grill pan 24 with the opening and closing of the grille door 2 3 the frame member 23a is in favor of grill pan 24 below the grill box To play a role.
[0013]
The grill pan 24 is formed by press-molding a thin plate in a substantially rectangular dish shape so that a substantially horizontal collar portion is formed around the thin plate, and then finishing coating such as fluororesin. At the four corners of the bottom plate of the grill pan 24, a grill net support 24a on which the grill net 25 is placed is formed. A support member 25a extending at a right angle to the net surface is provided at the front and rear ends of the grill net 25 for holding an object to be cooked such as fish in the grill cabinet. Then, before starting cooking on the grill 2, the support member 25 a is placed on the grill support unit 24 a so that the grill 25 is stored in the grill cabinet 21 together with the grill pan 24.
[0014]
By the way, the grill 2 according to the embodiment of the present invention can be used without putting water into the grill pan 24 in use. In the present embodiment, a projecting portion 21a that is substantially rectangular and has a convex shape when viewed in the downward direction of the grill cabinet is integrally formed at the substantially central portion of the bottom plate of the grill cabinet 21. The area of the projecting portion 21 a is smaller than the area of the bottom plate of the grill pan 24. In addition, a plurality of raised portions 21b are formed in the flat portion of the protruding portion 21a, and an air hole 21c is formed in the top portion. The height of the raised portion 21b can be set within a range that does not contact the grill plate 24 when the cook puts the grill plate 24 in and out of the grill cabinet 21, for example. Thereby, air is sucked from each air hole 21c of the raised portion 21b formed in the flat portion of the projecting portion 21a by the rising air current induced by the draft action in the refrigerator during grill cooking. In this case, air is sucked from the direction perpendicular to the grill pan 24 and directly collides with the bottom surface of the grill pan 24, so that the grill pan 24 is sufficiently and evenly cooled. In addition, a grill burner 26 that radiates and heats an object to be cooked placed on the grill is attached to the ceiling of the grill cabinet 21.
[0015]
The grill burner 26 is composed of a Schwann burner having a plurality of ceramic plates provided with a plurality of gas outlets penetrating therethrough, and the operation of the grill burner is attached to the front panel 13. 14a and the thermal power control lever 15b.
[0016]
By the way, when cooking on the grill 2, for example, when the cook forgets to cook on the grill 2, if the cooked food is left in the cooking state, a large amount of oily smoke is generated from the cooked food. In this case, more than a predetermined amount of oily smoke is generated, and when it directly contacts the combustion surface of the grill burner 26, the flame of the grill burner 26 is ignited by the oily smoke and is stored in the fat or grill pan 24 exposed on the surface of the cooking object. There is a risk that the oil content of the grilled broth will be ignited and the inside of the grill will be abnormally overheated. In this case, a temperature sensor can be provided on the inner surface of the exhaust tube 22 to constantly monitor the internal temperature, but this increases the cost. Therefore, in the present embodiment, the combustion exhaust of the grill burner 26 is deflected downward between the rear portion of the grill burner 26 and the front portion of the exhaust cylinder 22 and the object to be cooked placed on the grill net 25 is removed. A partition plate 27 that prevents oil smoke from coming into contact with the combustion surface of the grill burner 26 was suspended from the ceiling of the grill cabinet 21.
[0017]
Referring to FIG. 3, partition plate 27 is made of a heat-resistant material such as stainless steel, has a width corresponding to the width of grill cabinet 21, and the lower end of partition plate 27 has a grilled food placing surface. It is located higher. By providing such a partition plate 27, the combustion exhaust flow from the grill burner 26 is deflected downward. As a result, even if a large amount of oily smoke is generated from the food to be cooked by leaving the food to be cooked while cooking on the grill, the upward oil smoke is combined with the combustion exhaust deflected downward. Due to the inside draft operation, it flows horizontally below the partition plate 27 and is immediately guided to the exhaust tube 22. For this reason, since the oil smoke does not directly contact the combustion surface of the grill burner 26, the flame of the grill burner 26 can be prevented from igniting the oil smoke. Further, by preventing the ignition of oil smoke, the temperature inside the grill cabinet 21 is prevented from rising rapidly, and the ignition of the oil exposed to the fat exposed on the surface of the food to be cooked and the oil of the broth contained in the grill pan 24 is induced. Therefore, abnormal overheating inside the grill can be prevented.
