Description

【０００１】
【発明の属する技術分野】
本発明は、グリル庫内に設けられた加熱手段により被調理物を焼成するグリル装置に関するものである。
【０００２】
【従来の技術】
従来、グリル庫内に電熱ヒータ、ガスバーナ等の加熱手段を設け、該加熱手段によりグリル庫に収容された被調理物を焼成するグリル装置が知られている。前記グリル装置は、前記加熱手段の運転を制御する運転制御装置を備えており、該運転制御装置は該加熱手段による加熱の継続時間を計測する計時手段を備え、設定時間に達すると該加熱手段の運転を停止するようにして、消し忘れの防止を図っている。
【０００３】
また、前記グリル装置は、グリル庫内に収容される被調理物の下方に配設されたグリルパンを備え、被調理物の焼成を行うときには該グリルパンに水を貯留して、被調理物からグリルパンに落下した油を水面に浮遊させることにより、該油がグリルパンに接触して煙が出ることを防止するようになっている。前記構成のグリル装置では、前記グリルパンに温度センサを備え、該グリルパンに水が無くなると該温度センサが前記運転制御装置に水無し信号を出力して、該運転制御装置に前記加熱手段の運転を停止せしめている。
【０００４】
しかしながら、前記グリル装置では、前記グリルパンに対する水の供給を失念する等の理由で前記グリルパンの水が無いときには、グリル庫内の温度が低い状態で被調理物の焼成を開始したとき等のように前記油がグリルパンに接触しても直ちに煙が発生する虞れがない場合にも一律に前記加熱手段の運転が停止されるので、使用上不便を感じることがあるという不都合がある。
【０００５】
【発明が解決しようとする課題】
本発明は、かかる不都合を解消して、グリルパンの水が無い状態でも、グリル庫内の状況に応じて被調理物の焼成を続けることができるグリル装置を提供することを目的とする。
【０００６】
【課題を解決するための手段】
かかる目的を達成するために、本発明の第１の態様のグリル装置は、グリル庫と、該グリル庫内に設けられた加熱手段と、該加熱手段により焼成される被調理物の下方に配設されるグリルパンと、該グリルパンの温度を検知する第１の温度検知手段と、該加熱手段による加熱の継続時間を計測する第１の計時手段と、該加熱手段の運転を制御し該第１の計時手段により計測される時間が設定時間に達したときに該加熱手段の運転を停止する運転制御手段とを備えるグリル装置において、該加熱手段による加熱が開始されたときに該グリル庫内の温度が所定の温度未満か所定の温度以上かを判定する庫内温度判定手段を設け、該運転制御手段は、該庫内温度判定手段により判定される加熱開始時の庫内温度が所定の温度未満のときは、該第１の温度検知手段により検知されるグリルパンの温度が所定の温度を超えても、該第１の計時手段により計測される時間が該設定時間に達するまで該加熱手段の運転を継続してその後該加熱手段の運転を停止し、該庫内温度判定手段により判定される加熱開始時の庫内温度が所定の温度以上であるときには、該第１の温度検出手段の検知に応じて該加熱手段の運転を停止することを特徴とする。
【０００７】
本発明の第１の態様のグリル装置によれば、加熱手段による加熱が開始されると、まず、庫内温度判定手段により、グリル庫内の温度が所定の温度未満か所定の温度以上かが判定される。前記庫内温度判定手段により、グリル庫内の温度が所定の温度未満と判定されたときは、グリル庫内が冷えている状態から加熱が開始される所謂コールド・スタートの状態であるので、グリルパンに水が貯留されていなくとも被調理物からグリルパンに落下した油が直ちに過熱されることはなく、発煙する虞れが少ない。そこで、前記運転制御手段は、前記第１の温度検知手段により検知されるグリルパンの温度が所定の温度を超えてグリルパンの水が無くなったと判断されるときにも、前記第１の計時手段により計測される時間が設定時間に達するまで前記加熱手段の運転を継続して前記被調理物の焼成を終了させ、しかる後に前記加熱手段の運転を停止する。
【０００８】
一方、前記庫内温度判定手段により、グリル庫内の温度が所定の温度以上と判定されたときは、前回の調理により既にグリル庫内が温められている状態から加熱が開始される所謂ホット・スタートの状態であるので、状況によってはグリルパンに落下した前記油が過熱されて発煙する虞れがある。そこで、前記運転制御手段は、前記第１の温度検知手段により検知されるグリルパンの温度が所定の温度を超えてグリルパンの水が無くなったと判断されるときには、その状況に応じて加熱手段の運転を停止する。
【０００９】
従って、本発明の第１の態様のグリル装置によれば、グリルパンの水が無くなっても一律に加熱手段の運転が停止されることがなく、状況に応じて被調理物の焼成を続けることができる。
【００１０】
前記グリルパンの温度が所定の温度を超えてグリルパンの水が無くなったと判断されたときの対応として、本発明の第１の態様のグリル装置は、まず、前記運転制御手段が、所定の延長時間に達するまで前記加熱手段の運転を継続し、その後該加熱手段の運転を停止することを特徴とする。
【００１１】
前記第１の温度検知手段により検知されるグリルパンの温度が所定の温度を超えてグリルパンの水が無くなったと判断されるときでも、グリルパンの水が無くなれば直ちにグリルパンに落下した前記油が過熱されるわけではなく、該油が発煙する状態になるまでにはさらに時間がかかる。そこで、本発明のグリル装置では、前記第１の温度検知手段により検知されるグリルパンの温度が所定の温度を超えたときに、所定の延長時間に達するまで前記加熱手段の運転を継続することにより、前記油が発煙する状態になるまでの時間内でさらに被調理物の加熱を継続する。
【００１２】
このようにすることにより、グリルパンの水が無くなったと判断されるときでも、被調理物の加熱を継続し、可能な限りその焼成を終了させることができる。
【００１３】
また、本発明の第１の態様のグリル装置は、前記運転制御手段が、前記庫内温度判定手段により判定される加熱開始時の庫内温度が所定の温度以上であって、前記第１の温度検出手段により検知されるグリルパンの温度が所定の温度を超えたときに、前記設定時間の残り時間と所定の延長時間とを比較して該設定時間の残り時間が該延長時間より短いときには、該第１の計時手段により計測される時間が該設定時間に達するまで該加熱手段の運転を継続し、その後該加熱手段の運転を停止し、該設定時間の残り時間が該延長時間より長いときには、直ちに該加熱手段の運転を停止することを特徴とする。
【００１４】
本発明の第１の態様のグリル装置によれば、前記の様に前記設定時間の残り時間と所定の延長時間とを比較することにより、前記グリルパンの温度が所定の温度を超えてグリルパンの水が無くなったと判断されたときの状況に、さらに細かく対応することができる。
【００１５】
また、本発明の第１の態様のグリル装置において、前記庫内温度判定手段は、前記グリル庫内の温度を検知する第２の温度検知手段を備え、第２の温度検知手段により検知される温度に従って、該グリル庫内の温度が所定の温度未満か所定の温度以上かを判定するようにしてもよく、前記加熱手段の運転が停止されたのち、次の運転が開始されるまでの時間を計測する第２の計時手段を備え、該第２の計時手段により計測される時間が所定の時間以上であるときには前記グリル庫内の温度が所定の温度未満と判定し、該第２の計時手段により計測される時間が所定の時間未満であるときには前記グリル庫内の温度が所定の温度以上と判定するようにしてもよい。
【００１６】
また、前記構成のグリル装置では、前述の様にコールド・スタートの状態であれ、ホット・スタートの状態であれ、グリルパンの水が無くなっても、グリルパンに落下した前記油が直ちに過熱されて発煙する虞れは少ない。そこで、本発明の第２の態様のグリル装置は、グリル庫と、該グリル庫内に設けられた加熱手段と、該加熱手段により焼成される被調理物の下方に配設されるグリルパンと、該グリルパンの温度を検知する温度検知手段と、該加熱手段による加熱の継続時間を計測する計時手段と、該加熱手段の運転を制御し該計時手段により計測される時間が設定時間に達したときに該加熱手段の運転を停止する運転制御手段とを備えるグリル装置において、前記運転制御手段は、前記温度検出手段により検知されるグリルパンの温度が所定の温度を超えたときには、所定の延長時間に達するまで該加熱手段の運転を継続し、その後該加熱手段の運転を停止することを特徴とする。
【００１７】
本発明の第２の態様のグリル装置によれば、前記運転制御手段は、前記第１の温度検知手段により検知されるグリルパンの温度が所定の温度を超えてグリルパンの水が無くなったと判断されるときには、グリル庫内の温度状況、即ちコールド・スタートであるか、ホット・スタートであるかに係わり無く、前記所定の延長時間に達するまで前記加熱手段の運転を継続することにより、前記油が発煙する状態になるまでの時間内でさらに被調理物の加熱を継続する。
【００１８】
従って、本発明の第２の態様のグリル装置によれば、グリルパンの水が無くなったと判断されるときでも、前記所定の延長時間まで前記被調理物の焼成を続けることができる。また、本発明の第２の態様のグリル装置によれば、前記第１の態様の庫内温度判定手段が不要であり、装置の構成を簡単にできると共に、製造コストを低減することができる。
【００１９】
また、本発明の第２の態様のグリル装置は、前記温度検出手段により検知されるグリルパンの温度が所定の温度を超えたときに、前記運転制御手段が、前記設定時間の残り時間と所定の延長時間とを比較して該設定時間の残り時間が該延長時間より短いときには、該計時手段により計測される時間が該設定時間に達するまで該加熱手段の運転を継続して、その後該加熱手段の運転を停止し、該設定時間の残り時間が該延長時間より長いときには、直ちに該加熱手段の運転を停止することを特徴とする。
【００２０】
従って、本発明の第２の態様のグリル装置によれば、前記の様に前記設定時間の残り時間と所定の延長時間とを比較することにより、前記グリルパンの温度が所定の温度を超えてグリルパンの水が無くなったと判断されたときの状況に、細かく対応することができる。
【００２１】
【発明の実施の形態】
次に、添付の図面を参照しながら本発明の実施の形態についてさらに詳しく説明する。図１は本発明に係るグリル装置を備えるガステーブルの一構成例を示す斜視図であり、図２は図１示のグリル装置の要部断面図であり、図３は図１のガステーブルの第１の態様のシステム構成図であり、図４は図３示のグリル装置の作動を示すフローチャートである。また、図５は図１のガステーブルの第２の態様のシステム構成図であり、図６は図５示のグリル装置の作動を示すフローチャートである。
【００２２】
図１示のように、本実施形態のグリル装置１は、上面にガスこんろ２，３を備えるガステーブル４の本体５に内蔵されており、ガステーブル４の本体５の正面に設けられた開閉扉６から魚等の被調理物を出入自在となっている。また、ガステーブル４の本体５の正面には、グリル装置１の点・消火ボタン７、ガスこんろ２，３の点・消火ボタン８，９及びグリル装置１のバーナの火力調整つまみ１０が設けられている。尚、１１，１２はガスこんろ２，３の火力調整つまみ、１３はグリル装置１で発生する煙を外部に排出する排気口である。
【００２３】
図１示のガステーブル４では、点・消火ボタン７，８，９はいずれもハートカムによるプッシュ・プッシュ機構により作動するようになっている。すなわち、点・消火ボタン７，８，９は、それぞれ図示しないスプリングにより本体５の奥部から前面に向かって付勢されていて、突出位置（消火位置）から押圧されると押し込み位置（点火位置）に達し、この状態で押圧を解除すると中間位置（燃焼位置）に係止され、中間位置から再度押圧されて、該押圧が解除されると元の突出位置（消火位置）に復帰する様になっている。
【００２４】
前記グリル装置１は、図１示の開閉扉６の内部が、図２示のグリル庫１４となっている。グリル庫１４は、開閉扉６と一体となって前後に摺動自在のグリルパン１５を備え、グリルパン１５の上面を覆う様に設けられた焼き網１６に魚等の被調理物１７を載置してグリル庫１４内に収容し、グリル庫１４の天井に設けられた上火バーナ１８により被調理物１７を加熱、焼成するようになっている。
【００２５】
グリルパン１５は、焼き網１６の下方に設けられた傾斜板部１９と、傾斜板部１９の下端に連設された貯水槽２０とからなり、被調理物１７を加熱、焼成する際に貯水槽２０に水Ｗを入れておくことにより、グリルパン１５の過熱が防止され、被調理物１７からグリルパン１５に落下した油が発煙しにくくなっている。
【００２６】
尚、グリル装置１は、グリル庫１４内で発生した排気及び熱気を外部に排出するために、グリル庫１４内から排気口１３に連通する排気筒２１を備えると共に、その底部にはグリル庫１４内に外部から空気を導入する給気口２２を備えている。
【００２７】
次に、ガステーブル４の全体のシステム構成の第１の態様について説明する。
【００２８】
図３示のように、第１の態様のガステーブル４は、前記上火バーナ１８が設けられたグリル装置１、ガスこんろ２，３を備え、ガスこんろ２，３にはそれぞれこんろバーナ２３，２４が設けられている。各バーナ１８，２３，２４にはそれぞれガス供給導管２５から分岐する上火バーナ用ガス導管２６、こんろバーナ用ガス導管２７，２８が接続され、各ガス導管２６，２７，２８には燃料ガスの供給を制御する電磁弁２９，３０，３１と、火力調整つまみ１０，１１，１２により機械的に作動される火力調整弁（図示せず）とが設けられている。そして、各バーナ１８，２３，２４にはそれぞれ点火電極３２，３３，３４及び炎検知のための熱電対３５，３６，３７が付設されている。
【００２９】
また、グリル装置１は、グリルパン１５の貯水槽２０に、貯留された水がなくなったときに該グリルパン１５の温度上昇を検知する第１温度センサ３８が設けられ、グリル庫１４内に、上火バーナ１８に点火するとき（加熱開始時）の庫内温度を検出する第２温度センサ３９が設けられている。
【００３０】
ガステーブル４は、グリル装置１、ガスこんろ２，３の燃焼運転を制御するためのコントローラ４０を備えている。コントローラ４０は図示しないＣＰＵを備えるマイクロコンピュータであり、運転制御装置４１、庫内温度判定手段４２及びタイマ４３が設けられている。そして、運転制御装置４１は、各点・消火ボタン７，８，９により開閉される点・消火スイッチ７ａ，８ａ，９ａ、各電磁弁２９，３０，３１、各点火電極３２，３３，３４、各熱電対３５，３６，３７、第１温度センサ３８、庫内温度判定手段４２及びタイマ４３と電気的に接続され、庫内温度判定手段４２は第２温度センサ３９と電気的に接続されている。
【００３１】
次に、ガステーブル４の作動について説明する。
【００３２】
まず、ガスこんろ２または３の燃焼運転を行うときには、点・消火ボタン８または９を押圧して前記押し込み位置まで押し込むことにより、点・消火スイッチ８ａまたは９ａが閉じて、運転制御装置４１に点火信号が入力される。運転制御装置４１は、前記点火信号を受けると、押圧された点・消火ボタン８または９に対応する電磁弁３０または３１を開弁すると共に、対応する点火電極３３または３４を作動させ、対応するこんろバーナ２３または２４に着火し、燃焼運転を開始する。こんろバーナ２３または２４に着火すると、点・消火ボタン８または９は前記押圧を解除されて、中間位置に係止される。
【００３３】
こんろバーナ２３または２４の燃焼運転が開始されると、燃焼中のこんろバーナ２３または２４に対応する火力調整つまみ１１または１２により火力調整弁が操作され、こんろバーナ２３または２４の火力が調整され、鍋等の調理器Ｐ_１またはＰ_２の加熱が行われる。前記火力調整つまみ１１または１２による火力調整は、例えば、弱火、中火、強火の３段階で行うことができる。
【００３４】
そして、調理器Ｐ_１またはＰ_２による調理が終了して、燃焼中のこんろバーナ２３または２４に対応する点・消火ボタン８または９が再押圧されて前記中間位置から突出位置に復帰するか、対応する熱電対３６または３７が失火を検知すると、運転制御装置４１は対応する電磁弁３０または３１を閉弁して、燃焼運転を終了する。
【００３５】
次に、図３示のグリル装置１の燃焼運転について、図４を参照して説明する。グリル装置１の燃焼運転を行うときには、まず、開閉扉６を開いてグリルパン１５を取り出し、貯水槽２０に所定量の水Ｗを入れると共に、焼き網１６上に魚等の被調理物１７を載置する。次いで、被調理物１７が載置されたグリルパン１５をグリル庫１４内に収容し、開閉扉６を閉じたのち、点・消火ボタン７を押圧して前記押し込み位置まで押し込むことにより点・消火スイッチ７ａが閉じて、運転制御装置４１に点火信号が入力される。運転制御装置４１は、前記点火信号を受けると、電磁弁２９を開弁すると共に点火電極３２を作動させ、上火バーナ１８に着火し燃焼運転を開始する（ステップ１）。また、運転制御装置４１は前記燃焼運転が開始されると同時にタイマ４３を作動させ（ステップ２）、上火バーナ１８による加熱の継続時間の積算を開始する。
【００３６】
上火バーナ１８の燃焼運転が開始されると、点・消火ボタン７は前記押圧を解除されて、中間位置に係止される。また、火力調整つまみ１０により火力調整弁が操作されて上火バーナ１８の火力が調整され、被調理物１７の加熱、焼成が行われる。前記火力調整つまみ１０による火力調整は、例えば、弱火、中火、強火の３段階で行うことができる。
【００３７】
前記燃焼運転が開始され、運転制御手段４１がステップ３で第１温度センサ３８により検知される温度が所定の温度以下であってグリルパン１５に水があることを確認すると、通常の燃焼運転が行われる。このとき運転制御手段４１は、熱電対３５が失火を検知するか（ステップ４）、グリル装置１で被調理物１７の焼成が終了して点・消火ボタン７が再押圧されて前記中間位置から突出位置に復帰したとき（ステップ５）に、電磁弁２９を閉弁して、燃焼運転を終了する。また、運転制御装置４１は、ステップ５で点・消火ボタン７が再押圧されないときには、ステップ６でタイマ４３により積算される加熱継続時間が所定の設定時間に達すると、自動的に電磁弁２９を閉弁して燃焼運転を終了する（ステップ７）。尚、前記設定時間は、前記焼成の途中で消火することがなく被調理物１７を裏返す時間も加味して、例えば２４分間に設定されている。この設定時間は、加熱開始の前後に使用者の所望により調整することができる可変式としてもよいが、この場合も最長時間は例えば前記２４分間とするとよい。
【００３８】
次に、前記燃焼運転を開始するときにグリルパン１５に水Ｗを入れ忘れたか、前記燃焼運転の途中でグリルパン１５の水が無くなった場合には、グリルパン１５が上火バーナ１８により直接に加熱されて高温になる。そこで、運転制御装置４１はステップ３で第１温度センサ３８により検知される温度が所定の温度を超えることによりこれを検出する。そして、運転制御装置４１がグリルパン１５に水が無いものと判断したときに、本実施形態のグリル装置１は、一律に電磁弁２９を閉弁し燃焼運転を終了することなく、そのときのグリル庫１４内の状況に適した対応を行う。
【００３９】
前記グリル庫１４内の状況として、運転制御装置４１は、まずステップ８で、前記燃焼運転が開始されたときのグリル庫１４の庫内温度を参酌する。すなわち、庫内温度判定手段４２は、前記燃焼運転が開始されるときに、第２温度センサ３９によりグリル庫１４の庫内温度を検知し、所定温度未満のときにはグリル庫１４内が冷えている状態から加熱が開始される所謂コールド・スタートの状態と判定し、所定温度以上のときにはグリル庫１４内が既に温められている状態から加熱が開始される所謂ホット・スタートの状態と判定して、それぞれの場合の判定結果を運転制御装置４１に記憶させる。
【００４０】
そして、ステップ８で前記コールド・スタートであると判定された場合には、グリル庫１４内の温度が低く、グリルパン１５に水Ｗが貯留されていなくともグリルパン１５に落下した油が直ちに過熱されて発煙する虞れが少ないものとして、運転制御装置４１は、ステップ４〜７の作動を行い、前記設定時間に達するまで前記燃焼運転を継続し、前記設定時間に達すると、電磁弁２９を閉弁し燃焼運転を終了する。
【００４１】
また、ホット・スタートである場合には、グリル庫１４内の温度はコールド・スタートの場合よりも高いが、グリルパン１５に水Ｗが貯留されていないからといって、グリルパン１５に落下した油が直ちに過熱されるわけではない。従って、この場合には、運転制御手段４１は前記油が過熱、発火しない時間内でさらに所定の延長時間、例えば、３分間だけ前記燃焼運転を継続して被調理物１７をできるだけ焼成し、しかる後に電磁弁２９を閉弁し燃焼運転を終了するようにしてもよいが、前記グリル庫１４内の状況として、前記設定時間と前記延長時間との関係を参酌することにより、さらに細かい状況に対応することができる。
【００４２】
前記設定時間と前記延長時間との関係を参酌するときには、運転制御装置４１は、ステップ９で前記設定時間の残り時間と前記延長時間とを比較する。そして、前記設定時間の残り時間の方が短いときには、運転制御装置４１はグリルパン１５に落下した油が過熱されて発煙する虞れが十分に少ないものと判断し、ステップ４〜７の作動を行い、前記設定時間に達するまで前記燃焼運転を継続して被調理物１７の焼成を終了させ、しかる後に、電磁弁２９を閉弁し燃焼運転を終了する。
【００４３】
一方、運転制御装置４１は、ステップ９で前記設定時間の残り時間と前記延長時間とを比較して、前記設定時間の残り時間の方が長いときには、前記設定時間に達するまで前記燃焼運転を継続すると、グリルパン１５に落下した油が過熱されて発煙する虞れがあると判断し、直ちに電磁弁２９を閉弁し燃焼運転を終了する。
【００４４】
尚、運転制御装置４１は、ステップ８でホット・スタートであると判定された場合、前記のようにステップ９で前記設定時間の残り時間と前記延長時間とを比較することなく、直ちに電磁弁２９を閉弁して、燃焼運転を終了するようにしてもよい。
【００４５】
本実施形態で、庫内温度判定手段４２は、コールド・スタートかホット・スタートかの判断を、グリル庫１４内に設けられた第２温度センサ３９により前記燃焼運転が開始されるときの庫内温度を検知することにより行っているが、該庫内温度の検知は第１温度センサ３８により行うようにしてもよい。そして、さらにコントローラ４０に第２のタイマを設け、該第２のタイマにより、前記燃焼運転が停止されたのち、次の運転が開始されるまでの時間を計測し、その時間が所定の時間以上であるときにはコールド・スタートの状態と判定し、所定の時間未満であるときにはホット・スタートの状態と判定するようにしてもよい。またこのとき、前記第２のタイマとして、図３示のタイマ４３を兼用してもよい。
【００４６】
次に、ガステーブル４の全体のシステム構成の第２の態様について説明する。
【００４７】
図５示のように、第２の態様のガステーブル４は、図３示の庫内温度判定手段４２を備えていない以外は、前記第１の態様のガステーブル４と全く同一であるので、同一の構成には同一の符号を付して説明を省略する。
【００４８】
次に、図５示のグリル装置１の燃焼運転について、図６を参照して説明する。
【００４９】
図５示のグリル装置１の燃焼運転を行うときには、図３示のグリル装置１の場合と同様に、グリルパン１５を取り出して、貯水槽２０に所定量の水Ｗを入れ、魚等の被調理物１７を載置したグリルパン１５をグリル庫１４内に収容する。そして、開閉扉６を閉じたのち、点・消火ボタン７を押圧して燃焼運転を開始する（ステップ１）。運転制御装置４１は前記燃焼運転が開始されると同時にタイマ４３を作動させて（ステップ２）、上火バーナ１８による加熱の継続時間の積算を開始し、ステップ３で第１温度センサ３８により検知される温度が所定の温度以下であってグリルパン１５に水があることを確認すると、図３示のグリル装置１の場合と同様に、通常の燃焼運転が行われる（ステップ４〜７）。
【００５０】
次に、前記燃焼運転を開始するときにグリルパン１５に水Ｗを入れ忘れたか、前記燃焼運転の途中でグリルパン１５の水が無くなった場合には、運転制御装置４１はステップ３で第１温度センサ３８により検知される温度が所定の温度を超えることによりこれを検出する。そして、運転制御装置４１がグリルパン１５に水が無いものと判断したときに、本実施形態のグリル装置１は、一律に燃焼運転を終了することなく、そのときのグリル庫１４内の状況に適した対応を行う。
【００５１】
グリル装置１では、グリルパン１５に水Ｗが貯留されていないからといって、グリルパン１５に落下した油が直ちに過熱されて発煙するわけではない。そこで、この場合には、運転制御手段４１は前記油が過熱、発煙しない時間内でさらに所定の延長時間、例えば１０分間だけ前記燃焼運転を継続して被調理物１７をできるだけ焼成し、しかる後に電磁弁２９を閉弁し燃焼運転を終了するようにしてもよいが、運転制御装置４１はステップ８で前記設定時間と前記延長時間との関係を参酌することにより、前記グリル庫１４内の細かい状況に対応することができる。
【００５２】
ステップ８で前記設定時間と前記延長時間との関係を参酌するときには、運転制御装置４１は、前記設定時間の残り時間と前記延長時間とを比較し、前記設定時間の残り時間の方が短いときには、運転制御装置４１はグリルパン１５に落下した油が過熱されて発煙する虞れが十分に少ないものと判断し、ステップ４〜７の作動を行い、前記設定時間に達するまで前記燃焼運転を継続して被調理物１７の焼成を終了させ、しかる後に、電磁弁２９を閉弁し燃焼運転を終了する。
【００５３】
また、ステップ８で前記設定時間の残り時間と前記延長時間とを比較して、前記設定時間の残り時間の方が長いときには、前記設定時間に達するまで前記燃焼運転を継続すると、グリルパン１５に落下した油が過熱されて発煙する虞れがあると判断し、直ちに電磁弁２９を閉弁し燃焼運転を終了する。
【００５４】
尚、本実施形態の前記各態様で、運転制御装置４１は、前記のように第１温度センサ３８により検知される温度が所定の温度を超えた後（ステップ３でＮＯのとき）に、前記燃焼運転を継続している場合であっても、熱電対３５が失火を検知するか、点・消火ボタン７が再押圧されて前記中間位置から突出位置に復帰したときには、前記状況に関わりなく、電磁弁２９を閉弁して、燃焼運転を終了する。
【００５５】
また、前記各態様では、グリル装置１が上火バーナ１８のみを備え、片面焼きを行うものとして説明しているが、グリル装置１は焼き網１６とグリルパン１５との間から被調理物に熱気を与えて焼成する下火バーナを備えたものでもよく、さらに上火バーナ１８と前記下火バーナとの両方を備えたものでもよい。また、グリル装置１は、バーナの代わりに電熱ヒータ等、他の加熱手段を備えるものであってもよい。
【００５６】
また、前記各態様のグリルパン１５は傾斜板部１９と貯水槽２０とからなるものを示しているが、傾斜板部１９を備えず平底で底部全体を貯水槽２０とするものであってもよい。

[0002]
[Prior art]
2. Description of the Related Art Conventionally, there has been known a grill apparatus in which a heating unit such as an electric heater or a gas burner is provided in a grill storage, and the heating unit burns a cooking object stored in the grill storage. The grill device includes an operation control device that controls the operation of the heating unit. The operation control device includes a time measurement unit that measures a duration of heating by the heating unit. Is stopped to prevent forgetting to turn it off.
[0003]
The grill device further includes a grill pan disposed below the object to be cooked accommodated in a grill storage, and when firing the object to be cooked, water is stored in the grill pan, and the grill pan is moved from the object to be cooked. By floating the oil that has fallen on the water surface, the oil is prevented from coming into contact with the grill pan and emitting smoke. In the grill device having the above configuration, the grill pan includes a temperature sensor, and when the grill pan runs out of water, the temperature sensor outputs a water-less signal to the operation control device, and the operation control device controls the operation of the heating unit. It has been stopped.
[0004]
However, in the grill device, when there is no water in the grill pan due to, for example, forgetting to supply water to the grill pan, when firing of the object to be cooked is started in a state where the temperature in the grill chamber is low, or the like. Even when the oil contacts the grill pan, even if there is no possibility that smoke is immediately generated, the operation of the heating means is uniformly stopped, so that there is a disadvantage that inconvenience may be felt in use.
[0005]
[Problems to be solved by the invention]
An object of the present invention is to provide a grill apparatus that can solve the above-mentioned inconvenience and can continue to bake the object to be cooked in accordance with the situation in the grill storage even when there is no water in the grill pan.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a grill apparatus according to a first aspect of the present invention includes a grill storage, heating means provided in the grill storage, and an object disposed below an object to be baked by the heating means. A grill pan provided, first temperature detecting means for detecting the temperature of the grill pan, first time measuring means for measuring a duration of heating by the heating means, and a first timer for controlling the operation of the heating means. Operation control means for stopping the operation of the heating means when the time measured by the time measurement means reaches the set time, when the heating by the heating means is started, An internal temperature determining means for determining whether the temperature is lower than the predetermined temperature or higher than the predetermined temperature is provided, and the operation control means determines whether the internal temperature at the start of heating determined by the internal temperature determining means is the predetermined temperature. If less than the first Even if the temperature of the grill pan detected by the temperature detecting means exceeds a predetermined temperature, the operation of the heating means is continued until the time measured by the first timing means reaches the set time, and thereafter the heating means is operated. Is stopped, and when the internal temperature at the start of heating determined by the internal temperature determining means is equal to or higher than a predetermined temperature, the operation of the heating means is performed in response to the detection of the first temperature detecting means. It is characterized by stopping.
[0007]
According to the grill apparatus of the first aspect of the present invention, when the heating by the heating means is started, first, the inside temperature determining means determines whether the temperature inside the grill is lower than the predetermined temperature or higher than the predetermined temperature. Is determined. When the inside temperature of the grill is determined to be lower than the predetermined temperature by the inside temperature determining means, it is a so-called cold start state in which heating is started from a state in which the inside of the grill is cold. Even if no water is stored in the grill, the oil that has fallen from the object to be cooked onto the grill pan is not immediately overheated, and there is little risk of smoking. Therefore, the operation control means also measures the time by the first timing means when it is determined that the temperature of the grill pan detected by the first temperature detection means has exceeded a predetermined temperature and the water in the grill pan has run out. The operation of the heating means is continued until the set time reaches the set time to terminate the baking of the object to be cooked, and then the operation of the heating means is stopped.
[0008]
On the other hand, when the inside temperature of the grill is determined by the inside temperature determining means to be equal to or higher than the predetermined temperature, heating is started from a state in which the inside of the grill has already been heated by the previous cooking. In the start state, the oil that has fallen on the grill pan may be overheated and emit smoke depending on the situation. Therefore, when it is determined that the temperature of the grill pan detected by the first temperature detecting means exceeds a predetermined temperature and the grill pan has run out of water, the operation control means controls the operation of the heating means in accordance with the situation. Stop.
[0009]
Therefore, according to the grill apparatus of the first aspect of the present invention, even if the grill pan runs out of water, the operation of the heating means is not stopped uniformly, and the baking of the object to be cooked can be continued according to the situation. it can.
[0010]
As a response when it is determined that the temperature of the grill pan has exceeded a predetermined temperature and the water in the grill pan has run out, the grill apparatus according to the first aspect of the present invention first comprises the operation control means The operation of the heating means is continued until the temperature reaches the temperature, and thereafter, the operation of the heating means is stopped.
[0011]
Even when the temperature of the grill pan detected by the first temperature detecting means exceeds a predetermined temperature and it is determined that the water in the grill pan has run out, the oil that has fallen on the grill pan is immediately heated if the water in the grill pan runs out. It does not mean, however, that it takes more time for the oil to smoke. Therefore, in the grill device of the present invention, when the temperature of the grill pan detected by the first temperature detection unit exceeds a predetermined temperature, the operation of the heating unit is continued until a predetermined extension time is reached. Further, the heating of the object to be cooked is continued within the time until the oil fumes.
[0012]
In this way, even when it is determined that the grill pan has run out of water, it is possible to continue heating the object to be cooked and finish firing as much as possible.
[0013]
Further, in the grill device according to the first aspect of the present invention, the operation control means may be configured such that the inside temperature at the start of heating determined by the inside temperature determination means is equal to or higher than a predetermined temperature; When the temperature of the grill pan detected by the temperature detecting means exceeds a predetermined temperature, the remaining time of the set time is compared with a predetermined extension time, and when the remaining time of the set time is shorter than the extension time, When the operation of the heating means is continued until the time measured by the first timing means reaches the set time, the operation of the heating means is stopped thereafter, and when the remaining time of the set time is longer than the extension time, The operation of the heating means is immediately stopped.
[0014]
According to the grill apparatus of the first aspect of the present invention, by comparing the remaining time of the set time and the predetermined extension time as described above, the temperature of the grill pan exceeds the predetermined temperature and the Can be dealt with more finely when the situation is determined to have disappeared.
[0015]
Further, in the grill apparatus according to the first aspect of the present invention, the inside temperature determining means includes a second temperature detecting means for detecting a temperature inside the grill, and the temperature is detected by the second temperature detecting means. According to the temperature, it may be determined whether the temperature in the grill storage is lower than a predetermined temperature or higher than a predetermined temperature, and a time period from when the operation of the heating unit is stopped to when the next operation is started. A second time measuring means for measuring the temperature of the grill when the time measured by the second time measuring means is equal to or longer than a predetermined time. When the time measured by the means is less than a predetermined time, the temperature in the grill storage may be determined to be equal to or higher than a predetermined temperature.
[0016]
Further, in the grill device having the above-described configuration, the oil that has fallen on the grill pan is immediately heated and smokes, even in a cold start state or a hot start state as described above, even if the grill pan runs out of water. There is little fear. Therefore, a grill device according to a second aspect of the present invention includes a grill storage, a heating unit provided in the grill storage, and a grill pan disposed below the object to be cooked by the heating unit. Temperature detecting means for detecting the temperature of the grill pan, timing means for measuring the duration of heating by the heating means, and when the time measured by the timing means for controlling the operation of the heating means reaches a set time. Operation control means for stopping the operation of the heating means, the operation control means, when the temperature of the grill pan detected by the temperature detection means exceeds a predetermined temperature, a predetermined extended time The operation of the heating means is continued until the temperature reaches the temperature, and then the operation of the heating means is stopped.
[0017]
According to the grill apparatus of the second aspect of the present invention, the operation control means determines that the temperature of the grill pan detected by the first temperature detection means has exceeded a predetermined temperature and the grill pan has run out of water. Sometimes, the operation of the heating means is continued until the predetermined extension time is reached, irrespective of the temperature condition in the grill storage, that is, whether it is a cold start or a hot start, so that the oil is generated. The heating of the object to be cooked is continued within the time until the state where the food is cooked.
[0018]
Therefore, according to the grill apparatus of the second aspect of the present invention, even when it is determined that the water in the grill pan has been exhausted, the baking of the object can be continued until the predetermined extended time. Further, according to the grill apparatus of the second aspect of the present invention, the in-compartment temperature determining means of the first aspect is unnecessary, so that the configuration of the apparatus can be simplified and the manufacturing cost can be reduced.
[0019]
Further, in the grill device according to the second aspect of the present invention, when the temperature of the grill pan detected by the temperature detecting means exceeds a predetermined temperature, the operation control means may determine that the remaining time of the set time is equal to a predetermined time. When the remaining time of the set time is shorter than the extended time as compared with the extended time, the operation of the heating means is continued until the time measured by the timer reaches the set time, and then the heating means is Is stopped, and when the remaining time of the set time is longer than the extension time, the operation of the heating means is stopped immediately.
[0020]
Therefore, according to the grill apparatus of the second aspect of the present invention, by comparing the remaining time of the set time and the predetermined extension time as described above, the temperature of the grill pan exceeds the predetermined temperature, It is possible to respond to the situation when it is determined that the water has run out.

I have.
[0031]
Next, the operation of the gas table 4 will be described.
[0032]
First, when performing the combustion operation of the gas stove 2 or 3, the point / fire switch 8a or 9a is closed by pressing the point / fire button 8 or 9 and pushing the button to the pushing position. An ignition signal is input. When receiving the ignition signal, the operation control device 41 opens the solenoid valve 30 or 31 corresponding to the pressed point / extinguishing button 8 or 9 and activates the corresponding ignition electrode 33 or 34 to operate the corresponding ignition electrode 33 or 34. The burner 23 or 24 is ignited, and the combustion operation is started. When the stove burner 23 or 24 is ignited, the point / extinguishing button 8 or 9 is released from the pressing and is locked at the intermediate position.
[0033]
When the combustion operation of the stove burner 23 or 24 is started, the heat adjustment valve is operated by the heat adjustment knob 11 or 12 corresponding to the burning stove burner 23 or 24, and the heating power of the stove burner 23 or 24 is reduced. Adjusted cooking pot P such as pot ₁ Or P ₂ Is performed. The heating power adjustment by the heating power adjustment knob 11 or 12 can be performed in, for example, three stages of low heat, medium heat, and high heat.
[0034]
And cooker P ₁ Or P ₂ Is completed, the point / fire button 8 or 9 corresponding to the burning stove burner 23 or 24 is pressed again to return from the intermediate position to the protruding position, or the corresponding thermocouple 36 or 37 is turned off. When the misfire is detected, the operation control device 41 closes the corresponding solenoid valve 30 or 31, and ends the combustion operation.
[0035]
Next, the combustion operation of the grill device 1 shown in FIG. 3 will be described with reference to FIG. When performing the combustion operation of the grill device 1, first, the opening / closing door 6 is opened, the grill pan 15 is taken out, a predetermined amount of water W is poured into the water storage tank 20, and the food 17 such as fish is placed on the grill 16. Place. Next, the grill pan 15 on which the food 17 is placed is accommodated in the grill storage 14, the door 6 is closed, and then the dot / fire button 7 is pressed and pushed to the pushing position, whereby the point / fire switch is turned on. 7a is closed, and an ignition signal is input to the operation control device 41. Upon receiving the ignition signal, the operation control device 41 opens the solenoid valve 29 and activates the ignition electrode 32 to ignite the upper fire burner 18 and start the combustion operation (step 1). Further, the operation control device 41 activates the timer 43 at the same time when the combustion operation is started (step 2), and starts integrating the duration of heating by the upper fire burner 18.
[0036]
When the combustion operation of the upper fire burner 18 is started, the point / fire button 7 is released from the pressing, and is locked at the intermediate position. Further, the heating power adjusting knob 10 operates the heating power adjusting valve to adjust the heating power of the upper fire burner 18, thereby heating and baking the food 17. The heating power adjustment by the heating power adjustment knob 10 can be performed in, for example, three stages of low heat, medium heat, and high heat.
[0037]
When the combustion operation is started and the operation control unit 41 confirms in step 3 that the temperature detected by the first temperature sensor 38 is equal to or lower than the predetermined temperature and there is water in the grill pan 15, the normal combustion operation is performed. Is At this time, the operation control means 41 determines whether the thermocouple 35 detects a misfire (step 4), or the firing of the object 17 to be cooked by the grill device 1 is completed and the point / fire button 7 is pressed again from the intermediate position. When returning to the protruding position (step 5), the solenoid valve 29 is closed to terminate the combustion operation. In addition, when the point / fire extinguishing button 7 is not pressed again in step 5, the operation control device 41 automatically turns off the electromagnetic valve 29 when the heating duration time accumulated by the timer 43 reaches the predetermined set time in step 6. The valve is closed to end the combustion operation (step 7). Note that the set time is set to, for example, 24 minutes in consideration of the time for turning over the food 17 without extinguishing the fire during the baking. This set time may be a variable type that can be adjusted before and after the start of heating as desired by the user, but also in this case, the longest time may be, for example, the aforementioned 24 minutes.
[0038]
Next, if water W is forgotten in the grill pan 15 when starting the combustion operation, or if the water in the grill pan 15 runs out during the combustion operation, the grill pan 15 is directly heated by the upper fire burner 18. It gets hot. Therefore, the operation control device 41 detects that the temperature detected by the first temperature sensor 38 in step 3 exceeds a predetermined temperature. Then, when the operation control device 41 determines that there is no water in the grill pan 15, the grill device 1 of the present embodiment uniformly closes the solenoid valve 29 and terminates the combustion operation without ending the combustion operation. A response suitable for the situation in the storage 14 is performed.
[0039]
First, in step 8, the operation control device 41 considers the inside temperature of the grill storage 14 at the time when the combustion operation is started, as the situation inside the grill storage 14. That is, the inside temperature determining means 42 detects the inside temperature of the grill 14 by the second temperature sensor 39 when the combustion operation is started, and when the temperature is lower than the predetermined temperature, the inside of the grill 14 is cold. It is determined as a so-called cold start state in which heating is started from the state, and when the temperature is equal to or higher than a predetermined temperature, it is determined as a so-called hot start state in which heating is started from a state in which the inside of the grill storage 14 has already been heated, The operation control device 41 stores the determination results in each case.
[0040]
If it is determined in step 8 that the cold start has occurred, the temperature inside the grill pan 14 is low, and even if the water W is not stored in the grill pan 15, the oil that has fallen on the grill pan 15 is immediately heated, Assuming that there is little risk of smoke, the operation control device 41 performs the operations of steps 4 to 7, continues the combustion operation until the set time is reached, and closes the solenoid valve 29 when the set time is reached. The combustion operation is terminated.
[0041]
In the case of a hot start, the temperature inside the grill storage 14 is higher than that in the case of a cold start, but the oil that has fallen on the grill pan 15 may be reduced because the water W is not stored in the grill pan 15. It is not immediately overheated. Therefore, in this case, the operation control means 41 continues the combustion operation for a predetermined extended time, for example, 3 minutes within a time in which the oil does not overheat or ignite, and burns the food 17 as much as possible. Although the solenoid valve 29 may be closed later to terminate the combustion operation, a more detailed situation can be dealt with by considering the relationship between the set time and the extended time as the situation in the grill storage 14. can do.
[0042]
When considering the relationship between the set time and the extension time, the operation control device 41 compares the remaining time of the set time with the extension time in step 9. When the remaining time of the set time is shorter, the operation control device 41 determines that there is a sufficiently low possibility that the oil dropped on the grill pan 15 is overheated and smoke is generated, and performs the operations of steps 4 to 7. Then, the combustion operation is continued until the set time is reached, and the firing of the article to be cooked 17 is terminated. Thereafter, the solenoid valve 29 is closed to terminate the combustion operation.
[0043]
On the other hand, the operation control device 41 compares the remaining time of the set time with the extension time in step 9 and, when the remaining time of the set time is longer, continues the combustion operation until the set time is reached. Then, it is determined that the oil dropped on the grill pan 15 may be overheated to cause smoke, and the solenoid valve 29 is closed immediately to terminate the combustion operation.
[0044]
When it is determined in step 8 that the start is a hot start, the operation control device 41 immediately proceeds to the solenoid valve 29 without comparing the remaining time of the set time with the extension time in step 9 as described above. May be closed to end the combustion operation.
[0045]
In the present embodiment, the inside temperature determining means 42 determines whether the operation is cold start or hot start by the second temperature sensor 39 provided in the grill case 14 when the combustion operation is started. Although the detection is performed by detecting the temperature, the detection of the internal temperature may be performed by the first temperature sensor 38. Further, a second timer is provided in the controller 40, and the second timer measures the time from when the combustion operation is stopped to when the next operation is started, and the time is measured for a predetermined time or more. , A cold start state may be determined, and if less than a predetermined time, a hot start state may be determined. At this time, the timer 43 shown in FIG. 3 may also be used as the second timer.
[0046]
Next, a second embodiment of the overall system configuration of the gas table 4 will be described.
[0047]
As shown in FIG. 5, the gas table 4 of the second embodiment is exactly the same as the gas table 4 of the first embodiment except that the gas table 4 of FIG. The same components are denoted by the same reference numerals, and description thereof is omitted.
[0048]
Next, the combustion operation of the grill device 1 shown in FIG. 5 will be described with reference to FIG.
[0049]
When performing the combustion operation of the grill apparatus 1 shown in FIG. 5, the grill pan 15 is taken out, a predetermined amount of water W is put into the water storage tank 20, and cooking of fish or the like is performed, similarly to the grill apparatus 1 shown in FIG. The grill pan 15 on which the object 17 is placed is housed in the grill storage 14. After the door 6 is closed, the combustion operation is started by pressing the fire button 7 (step 1). The operation control device 41 activates the timer 43 at the same time when the combustion operation is started (step 2), starts integration of the duration of heating by the upper fire burner 18, and detects by the first temperature sensor 38 in step 3. When it is confirmed that the temperature to be performed is equal to or lower than the predetermined temperature and there is water in the grill pan 15, a normal combustion operation is performed as in the case of the grill apparatus 1 shown in FIG. 3 (steps 4 to 7).
[0050]
Next, if the operator forgets to fill the grill pan 15 with water W when starting the combustion operation, or if the grill pan 15 runs out of water during the combustion operation, the operation control device 41 determines in step 3 that the first temperature sensor 38 Is detected when the temperature detected by exceeds a predetermined temperature. When the operation control device 41 determines that there is no water in the grill pan 15, the grill device 1 of the present embodiment is suitable for the situation in the grill storage 14 at that time without ending the combustion operation uniformly. Take action.
[0051]
In the grill device 1, just because the water W is not stored in the grill pan 15, the oil that has fallen on the grill pan 15 is not immediately heated and smoke is generated. Therefore, in this case, the operation control means 41 further continues the combustion operation for a predetermined extension time, for example, 10 minutes within a time period in which the oil does not overheat or emit smoke, and burns the food 17 as much as possible. Although the solenoid valve 29 may be closed to end the combustion operation, the operation control device 41 considers the relationship between the set time and the extended time in step 8 to thereby perform finer operations in the grill storage 14. Can respond to the situation.
[0052]
When considering the relationship between the set time and the extension time in step 8, the operation control device 41 compares the remaining time of the set time with the extension time, and when the remaining time of the set time is shorter, The operation control device 41 determines that there is a sufficiently low possibility that the oil dropped on the grill pan 15 is overheated and emits smoke, performs the operations in steps 4 to 7, and continues the combustion operation until the set time is reached. Then, the baking of the article 17 is terminated, and thereafter, the solenoid valve 29 is closed to terminate the combustion operation.
[0053]
In step 8, the remaining time of the set time is compared with the extended time. If the remaining time of the set time is longer, the combustion operation is continued until the set time is reached. It is determined that the oil that has been heated is likely to be overheated and smoke is generated, and the solenoid valve 29 is immediately closed to terminate the combustion operation.
[0054]
In addition, in each of the above aspects of the present embodiment, the operation control device 41 performs the above-described operation after the temperature detected by the first temperature sensor 38 exceeds a predetermined temperature as described above (NO in step 3). Even when the combustion operation is continued, when the thermocouple 35 detects misfire or when the point / fire extinguishing button 7 is pressed again to return to the projecting position from the intermediate position, regardless of the situation, The solenoid valve 29 is closed to end the combustion operation.
[0055]
Further, in each of the above embodiments, the grill device 1 is described as being provided with only the upper fire burner 18 and performing single-sided grilling. However, the grill device 1 applies hot air from between the grill 16 and the grill pan 15 to the cooking object. May be provided with a lower fire burner for baking by applying the heat, and furthermore, both a lower fire burner 18 and the lower fire burner may be provided. Further, grill device 1 may include another heating means such as an electric heater instead of a burner.
[0056]
Although the grill pan 15 in each of the above-described embodiments includes the inclined plate portion 19 and the water storage tank 20, the grill pan 15 may not include the inclined plate portion 19 and have a flat bottom and the entire bottom portion as the water storage tank 20. .
