Description

【０００１】
【発明の属する技術分野】
本発明は、お好み焼、肉類加熱調理に使用する鉄板焼き器に関し、特にバーナーの炎を視認する鉄板焼き器における反射板に関する。
【０００２】
【従来の技術】
従来、鉄板焼き器としては、特開平１１−６３４８７号公報に見られる、バーナーを内装した内箱にバーナーの炎の有無を検出するための温度センサが着脱自在に設けられたクッキングテーブルの燃焼装置において、前記温度センサの温度検出部がバーナーの炎口近傍に位置するように前記温度センサを位置決めする位置決め手段を備えたもの、内箱に、バーナーの炎を映す反射板が設けられたもの、バーナーの側方に沿って遮熱板が内箱に対して着脱自在に設けられたクッキングテーブルの燃焼装置が知られている。
そして、内箱の左右の上部両側には、吸排気兼放熱用の複数のスリットが形成されたステンレス製の覆板が配され、内箱の前後の側壁および飾り枠に着脱自在に支持され、覆板の一端は、下方に向かって延設され、スリットの下方に達するように内側に向かって一体的に折曲形成され、この傾斜した部分が鏡面仕上げされ、バーナーの炎を映す反射板とされている。
【０００３】
上記反射板を利用して炎を視認するためには、覆板のスリットと反射板の平面視位置が同一であるため、視認者は真上から視認する必要がある。
しかしながら、覆板を取付ける内箱（燃焼装置）は天板中央に取付けられているため、天板を上半身が覆い被さった状態でスリットの真上から視認するという、不安定かつ不自然な姿勢を強いられていた。
【０００４】
又、反射板はスリットの下方位置に設けられているが、当該位置は吸排気位置でもあるため、燃焼ガスが反射板に接触して反射板を曇らせて炎視認状態を悪化させていた。
更に、スリットが形成された覆板に隣接するプレートの１辺には屑落下口が設けられているため、調理カス等が落下されて反射板に付着して汚れ易かった。
【０００５】
【発明が解決しようとする課題】
本発明は、楽な姿勢で炎視認を行えると共に、反射板の汚れを防止する様にした鉄板焼き器における反射板を提供する。
【０００６】
【課題を解決するための手段】
本発明は、上記従来技術に基づく、炎視認に不自然な姿勢を強いられたり、反射板が曇る課題に鑑み、天板の中央に設けたケーシングの上面開口の端部にスリットを有する排気口カバーを設けると共に、該排気口カバーに隣接する位置に屑落下口を設けた鉄板を載置し、ケーシングの中間部にバーナーを配置すると共に、屑落下口及び排気口カバーの下方で且つバーナーより下方にダストトレーを抜出し自在に設け、ダストトレーにおけるトレー部材の後方の立側壁から後方に反射板となる傾斜板を設けることによって、自然で楽な姿勢で炎視認したり、反射板が曇らない様にして、上記課題を解決する。
【０００７】

鉄板１３は上面略全周に突堤２２を突設すると共に、裏面所定個所に突起２３を設け、該裏面突起２３に固定した水平板２４の内縁端側で鉄板１３の下面から垂下させた一対の遮熱板２５を連結固定すると共に、該遮熱板２５の下端を内方側に折曲して遮熱ガイド２５ａ　を設け、又鉄板１３の下面に設けた水平板２４をケーシング１０の内方に設けた蝶ボルト１９の上端に載置している。
【００１１】
図１、６、１０に示す様に、鉄板１３の長手方向端部の一側中央に矩形状の屑落下口２６を設けると共に、鉄板１３の表面外周突堤２２は屑落下口２６の部分において設けていない。
又、鉄板１３の長手端部両外側でケーシング１０に設けた排気口カバー１２ａ　、１２ｂ　は断面視門形状で、ケーシング１０の立側壁１４、１４ａ　…上部に設けた折曲板の内面と鉄板１３の外周縁との間に嵌合支持すると共に、排気口カバー１２ａ　、１２ｂ　の上面板に多数のスリット２７、２７ａ　…を設けている。
そして、折曲板下端から内方下方側に傾斜折曲したガイド板１６は長手側両側部において排気口カバー１２ａ　、１２ｂ　の下方に位置している。
【００１２】
図２、４、６に示す様に、調理器本体４に内装したバーナー１１は棒状の２本平行のバーナー管２８、２８ａ　を保持板２９、２９ａ　…で支持して長手方向に架設し、ガス元栓（ホースエンド）が設置されている方向で、即ち、短手側のケーシング１０の立側壁１４、１４ａ　…、キャビネット９の短手立側壁３１ｄ　、３１ｅ　を貫通して外方突出させている。
又、ケーシング１０内におけるバーナー管２８、２８ａ　の基端側では、２本平行のバーナー管２８、２８ａ　に連通する中継管３２を連結し、２本のバーナー管２８、２８ａ　及び中継管３２の上面に炎口３３、３３ａ　…を設けると共に、ガス元栓に接続する器具栓３４、メイン連絡管３５、レギュレータ３６、３６ａ　等のガス供給部３７を外方突出したバーナー管２８、２８ａ　の基端に取付けている。
図２、６に示す様に、バーナー管２８、２８ａ　を連結した中継管３２の近傍に設けた保持板３８にパイロット３９及びサーモカップル（熱電対）４０を炎口３３、３３ａ　…方向に夫々取付け、パイロット３９及びサーモカップル４０に接続するガス管等４１、電気配線４２を基端側に貫通突出させている。
又、器具栓３４等の長手方向反対側で天板２の下面にガス点火、消火、火力調整する遠隔操作部４３を設け、器具栓３４、パイロット３９、サーモカップル４０、遠隔操作部４３等を適宜連結している。
【００１３】
図３、４、６、１０に示す様に、ケーシング１０の底部にはガイド部４４、４４ａ　を設けてドレインパン４５を長手方向で、ガス元栓の反対側で遠隔操作部４３側に抜出し自在に設けると共に、ドレインパン４５より上方、且つ、バーナー１１より下方で、鉄板１３に設けた屑落下口２６及び排気口１２、排気口カバー１２ａ　の下方位置にガイド板４６上でダストトレー４７を遠隔操作部４３側の長手方向に抜出し自在に設けている。
かかる構成により、ケーシング１０の底部ではバーナー１１より下方でドレインパン４５の上部にダストトレー４７を２層構造で長手方向に抜出し自在に設け、ドレインパン４５の一部にダストトレー４７が重層する状態となっている。
尚、ケーシング１０の立側壁１４、１４ａ　…、キャビネット９の立側壁３１、３１ａ　には抜出し用の開口部４８、開口部４９を設けている。
【００１４】
図６、７、８に示す様に、バーナー１１の底部に抜出し自在に設けたドレインパン４５は、大小複数のパン部材５０、５０ａ　…に抜出し長手方向に連結分割自在であり、パン部材５０、５０ａ　…の抜出し方向基端（手前）である一方の立側壁５１に抜出し方向外側に門形状の係止部５２を突設し、該係止部５２の水平上面部５３は抜出し方向先端である他方の立側壁５１ａ　の上方に位置すると共に、水平上面部５３先端から垂下形成した垂下部５４の下端位置は他方の立側壁５１ａ　の上端より低くし、パン部材５０、５０ａ　…の抜出し方向先端（奥方）の立側壁５１ａ　を被係止部５２ａ　と成している。
尚、他方のパン部材５０、５０ａ　…端部の立側壁５１ａ　（被係止部５２ａ　）を被覆する門形状の係止部５２は抜出し側に設けることが好ましく、且つ、水平上面部５３は把手として使用可能な大きさが好ましい。
【００１５】
図７、８に示す様に、複数のパン部材５０、５０ａ　…の抜出し長手方向長さは大小あり、長寸（長さＭＬ、ＬＬ）のパン部材５０は厨房での清掃が可能な長さであり、短寸（長さＬ）のパン部材５０ａ　、５０ｂ　は適宜長さとし、長寸のパン部材５０は短寸のパン部材５０ａ　、５０ｂ　の２倍以上の長さ（２Ｌ＜ＭＬ、ＬＬ）としている。
図示のものでは、長寸のパン部材５０が１枚と短寸のパン部材５０ａ　、５０ｂ　の２枚を順次係止部５２と被係止部５２ａ　で連結している。
そして、長寸のパン部材５０を、長さＭＬ、ＬＬの２種類とした場合の適用例が図７に示されており、鉄板焼き器１（又は鉄板１３、ドレインパン４５）の全長が２種類のものであった場合、その全長差ΔＬと同等の全長差ΔＬを有する全長ＭＬとＬＬのパン部材５０の２種類とすることにより、部材を共用化する。
尚、複数のパン部材５０、５０ａ　…は大小各種長さのものと成したが、全てのパン部材５０、５０ａ　…を同寸と成しても良い。
【００１６】
図９（ａ）　、（ｂ）　、１０に示す様に、ダストトレー４７は上面開口箱状のトレー部材５５の抜出し方向後方（長手方向内方）の立側壁５６の上端から内方下方に傾斜板５７を設けて、該傾斜板５７を反射板５８と成している。
上記説明では、傾斜板５７はトレー部材５５の後方の立側壁５６に設けたが、図示する様に、トレー部材５５の手前の立側壁５６ａ　にも設け、前後方同一構成と成し、手前の傾斜板５７ａ　を把持把手６０と成している。
上述の排気口１２等との構成により、ダストトレー４７は鉄板１３の屑落下口２６、排気口カバー１２ａ　のスリット２７、２７ａ　…の下方に位置すると共に、ダストトレー４７の先端に設けた反射板５８となる傾斜板５７は鉄板１３の屑落下口２６より内方に位置することとなり、図１０に示す様に、天板２の外側から反射板５８を介してバーナー１１の炎を見る視線範囲Ｓは広角度傾斜範囲となり、図示のものでは約４５度を中心として前後１０度ずつの範囲となっている。
又、図９（ｃ）　に示す様に、トレー部材５５の手前の立側壁５６ａ　に設けた傾斜板５７ａ　の先端から垂下板５９ａ　を設けて、傾斜板５７ａ　及び垂下板５９ａ　で把手６０と成しても良く、この場合にもトレー部材５５を前後方同一構成と成すべく、後方の傾斜板５７にも垂下板５９を設けても良い。
【００１７】
尚、本発明に係る鉄板焼き器１は無煙鉄板焼き器とすることも出来、例えば、ケーシング１０の外部に所定間隔の吸引流路を有する様に吸引作用される外箱を取付け、鉄板１３の上面等で発生する焼煙等を吸引流路に吸引して無煙鉄板焼き器としても良い。
【００１８】
次に本発明に係る鉄板焼き器の作用について説明する。
遠隔操作部４３の点火操作、熱量操作により、バーナー１１のバーナー管２８、２８ａ　及び中継管３２の炎口３３、３３ａ　…から噴出し燃焼するガス炎が上昇して、鉄板１３の下面に到達した燃焼ガスで鉄板１３を加熱し、鉄板１３の上面でお好み焼、肉類等を加熱調理する。
鉄板１３の下面を加熱する際、上昇した燃焼ガスは一対の遮熱板２５で拡散を防止されて鉄板１３の中央を集中的に効率良く加熱すると共に、ケーシング１０の長手方向立側壁１４、１４ａ　…を加熱せずに排気ガスは長手方向に流動し、排気口１２に設けた傾斜状のガイド板１６に沿って上昇した排気ガスは排気口カバー１２ａ　、１２ｂ　のスリット２７、２７ａ　…及び鉄板１３の屑落下口２６から排気される。
尚、ガス燃焼に際して、二次空気は吸気孔１７、１７ａ　…から吸気され、一対の遮熱板２５による燃焼ガスの拡散防止流動時に、遮熱板２５下端に設けた遮熱ガイド２５ａ　により遮熱板２５下端からの溢流を抑制したり、遮熱ガイド２５ａ　による強度向上で遮熱板２５の変形を防止し、又調理器本体４の温度上昇した器体熱はキャビネット９の底壁３１ｂ　、３１ｃ　間の開口から放熱される。
【００１９】
調理開始後のガス炎状態確認、火力調整に際しては、一方のガス燃焼確認（立ち消え確認）はガス炎によるサーモカップル４０の熱上昇で行い、立ち消え時はサーモカップル４０の温度低下による熱起電力消失（検知異常）でガス供給を自動停止し、他方の火力調整は遠隔操作部４３で行い、これらと並行して、排気口カバー１２ａ　、１２ｂ　のスリット２７、２７ａ　…及び鉄板１３の屑落下口２６からガス炎状態を目視確認する。
この視認状態は図１０に示す様に、従業員又は飲食客が天板２の外側から目線が下方傾斜状態でスリット２７、２７ａ　…又は屑落下口２６を覗き、該屑落下口２６の内方（奥方）下方側に位置するダストトレー４７先端に設けた反射板５８を介してガス炎を視認する。
【００２０】
次に、清掃等について説明する。
鉄板１３は水平に配置する必要があるので、鉄板焼き器１の設置時に、台部の水平調整部５、５ａ…で鉄板焼き器１を水平設置し、鉄板１３の載置時には蝶ボルト１９の上下調整で鉄板１３を水平載置する。
調理器本体４の上端内面と鉄板１３の隙間においては、支持板２０上に圧入嵌合されたチューブパッキン２１、２１ａ　の上端が調理器本体４における外方折曲部１５及び鉄板１３における表面突堤２２の上端と略同一となって隙間にカス屑は残留したり落下しない。
又、長時間使用で細屑が残留した時には、チューブパッキン２１、２１ａ　の一端を引き上げることにより、２辺全長のチューブパッキン２１、２１ａ　を上方離脱させて、細屑を取り除き、清掃完了後に隙間の支持板２０上にチューブパッキン２１、２１ａ　を圧入し、縦長変形状態で嵌合する。
【００２１】
調理時における調理カスは、鉄板１３の屑落下口２６から下方のダストトレー４７に落下させ、飛散油分、ガス燃焼その他の細粒成分はドレインパン４５に落下し、燃焼ガスは排気口カバー１２ａ　、１２ｂ　のスリット２７、２７ａ　…を通過するため、これらの清掃を行う。
調理カスが落下回収されたダストトレー４７は、長手方向の遠隔操作部４３側に把手６０を利用して抜出・清掃し、ダストトレー４７の器体内方側に設けた反射板５８はバーナー管２８、２８ａ　より下方で屑落下口２６等より内方側（奥行側）で汚濁は少ないが、汚れ程度に応じて清掃する。
鉄板１３の長手方向両側の排気口１２に設けた排気口カバー１２ａ　、１２ｂ　は、上方から着脱して清掃する。
【００２２】
又、ダストトレー４７と上下２層構造となっているドレインパン４５もダストトレー４７と同様に、長手方向の遠隔操作部４３側に抜出して清掃する。
ドレインパン４５の抜出しに際しては、遠隔操作部４３側基端の第１段のパン部材５０をガイド部４４、４４ａ　から離脱する位置まで引出し、パン部材５０の先端を若干降下させ、ガイド部４４、４４ａ　で高さ保持されている第２段のパン部材５０ａ　の水平上面部５３及び垂下部５４から成る係止部５２から第１段のパン部材５０の立側壁５１ａ　から成る被係止部５２ａ　を離脱させ、第２段のパン部材５０ａ　から第１段のパン部材５０を分離し、第１段のパン部材５０をケーシング１０から抜出す。
そして、基端位置に移動した第２段のパン部材５０ａ　をガイド部４４、４４ａ　から離脱する位置まで引出し、同様操作で第３段のパン部材５０ｂ　から第２段のパン部材５０ａ　を離脱させて抜出し、以下同様に最後段のパン部材５０ｃ　を抜出す。
【００２３】
ドレインパン４５が短く複数分割されたパン部材５０、５０ａ　…を厨房等で清掃し、稼働状態への復元設定は、ガイド部４４、４４ａ　に押し込み載置した最後段のパン部材５０ｃ　の係止部５２と１段前段のパン部材５０ｂ　の被係止部５２ａ　を係止させると共に、前段のパン部材５０ｂ　を奥行き方向に押し込み、順次、第１段のパン部材５０を係止、押込作業して、複数のパン部材５０、５０ａ　…を連結したドレインパン４５をケーシング１０のガイド部４４、４４ａ　内に挿入して稼働状態に設定する。
【００２４】
【発明の効果】
要するに本発明は、天板２の中央に設けたケーシング１０の上面開口の端部にスリット２７、２７ａ　…を有する排気口カバー１２ａ　、１２ｂ　を設けると共に、該排気口カバー１２ａ　、１２ｂ　に隣接する位置に屑落下口２６を設けた鉄板１３を載置したので、鉄板１３を加熱したバーナー１１の燃焼ガスは排気口１２から排気され、調理カス等は屑落下口２６から落下させることが出来、又ケーシング１０の中間部にバーナー１１を配置すると共に、屑落下口２６及び排気口カバー１２ａ　、１２ｂ　の下方で且つバーナー１１より下方にダストトレー４７を抜出し自在に設けたので、落下させた調理カス等をダストトレー４７に回収し取出すことが出来たり、ダストトレー４７に設けた反射板５８は屑落下口２６より内方でバーナー１１より下方となるため、排気される燃焼ガスや落下屑で反射能を低減させることがない。
又、ダストトレー４７におけるトレー部材５５の後方の立側壁５６から後方に反射板５８となる傾斜板５７を設けたので、反射板５８は屑落下口２６及び排気口１２のスリット２７、２７ａ　…より内方側（中央寄り）となるため、反射板５８を利用した炎の視認方向は傾斜し、天板２の外側からでも楽な姿勢で炎を視認することが出来、更に、抜出し自在なダストトレー４７に反射板５８を設けることにより、反射板５８の着脱、清掃を容易に行うことが出来る。
【００２５】
トレー部材５５の手前の立側壁５６ａ　に傾斜板５７ａ　を設けたので、トレー部材５５の前後端は同一形状と成り、手前側の傾斜板５７ａ　が把手６０となってダストトレー４７の出入を容易に行うことが出来る。
又、図９（ｃ）　の実施例に示す様に、トレー部材５５の手前の立側壁５６ａ　に設けた傾斜板５７ａ　の先端に垂下板５９ａ　を設けることにより、垂下板５９ａ　も把手６０として利用すると、ダストトレー４７の出入作業を更に容易化することが出来る。
【００２６】
長手方向一側にドレインパン４５とダストトレー４７の両方を抜出し自在に設けたので、通路側に位置する長手方向一側からドレインパン４５とダストトレー４７の抜出し操作を容易に行うことが出来、両者共に清掃が必要なドレインパン４５とダストトレー４７の抜出し方向を長手方向とすることにより、客席側に面する両側面を抜出し構成が不要な同一構成として、コストダウンを図ることが出来る。
【００２７】
排気口１２を設けない鉄板１３の２辺外周と調理器本体４のケーシング１０の内面の隙間に支持板２０を水平方向に固定したので、支持板２０上に圧入するチューブパッキン２１、２１ａ　の上端位置を鉄板１３の上端位置に一致させて容易に取付けることが出来、又支持板２０上で前記隙間にチューブパッキン２１、２１ａ　を圧入したので、鉄板１３の外周とケーシング１０の隙間をチューブパッキン２１、２１ａ　で閉鎖してカス屑等の残留を防止して衛生面を向上させることが出来たり、閉鎖部材はチューブパッキン２１、２１ａ　と成すことにより、隙間なく圧入嵌入させたり、一本状で着脱を容易に行うことが出来る等その実用的効果甚だ大である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a teppanyaki used for okonomiyaki and meat heating cooking, and more particularly to a reflector in a teppanyaki that visually recognizes the burner flame.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as an iron plate grilling device, there is a cooking table combustion device disclosed in JP-A-11-63487, in which a temperature sensor for detecting the presence or absence of flame of a burner is detachably provided in an inner box containing a burner. In the one provided with positioning means for positioning the temperature sensor so that the temperature detection part of the temperature sensor is located near the flame opening of the burner, the inner box is provided with a reflector that reflects the burner flame, 2. Description of the Related Art There is known a cooking table combustion device in which a heat shield plate is provided detachably with respect to an inner box along a side of a burner.
A stainless steel cover plate having a plurality of slits for intake / exhaust and heat dissipation is disposed on both left and right upper sides of the inner box, and is detachably supported on front and rear side walls and a decorative frame of the inner box, One end of the cover plate extends downward and is integrally bent inward so as to reach below the slit, and the inclined portion is mirror-finished, and a reflection plate reflecting the burner flame. Have been.
[0003]
In order to visually recognize the flame using the above-mentioned reflector, since the slit of the cover plate and the position of the reflector in plan view are the same, the viewer must visually recognize the flame from directly above.
However, since the inner box (combustion device) for attaching the cover plate is mounted in the center of the top plate, it has an unstable and unnatural posture in which the top plate can be viewed from directly above the slit with the upper body covered. I was compelled.
[0004]
Further, although the reflector is provided at a position below the slit, since this position is also an intake / exhaust position, the combustion gas comes into contact with the reflector and foggs the reflector, thereby deteriorating the state of flame recognition.
Furthermore, since a scrap drop opening is provided on one side of the plate adjacent to the cover plate having the slit formed thereon, cooking wastes and the like are dropped and adhere to the reflecting plate, so that they are easily stained.
[0005]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention provides a reflector in an iron plate grill which can visually recognize a flame in a comfortable posture and prevents the reflector from being stained.
[0006]
[Means for Solving the Problems]
