Description

【０００１】
【発明の属する技術分野】
本発明は、主に所定のパン材料を機器に準備するだけで自動的にパンの製造を行なうことが出来る一般家庭で使用するパン製造機に関する。
【０００２】
【従来の技術】
近年、食文化の多様化・高級化に伴い、家庭用パン製造機を用いて、レーズン、ナッツ類あるいはチーズ等の製パン副材料を加えたレーズンパン、ナッツパン、あるいはチーズパン等を家庭でも焼くようになってきた。
【０００３】
この種のパン製造機としては、例えば、特許文献１に記載されているようなものがあった。図９は、前記特許文献１に記載された従来のパン製造機の断面図である。
【０００４】
図９において、本体１内に設けたシャーシ２はその上部に加熱手段であるヒータ３を内蔵した焼成室４をパン容器取り付け台５により狭持して固定しており、下部にはモータ６を固定している。またシャーシ２は下端部で底板７により板金製の本体１を狭持して固定している。８は焼成室４を開閉する外蓋である。パン容器９は、パン容器取り付け台５に着脱自在に載置されており、パン容器９内の中央底部には上方に混練手段としての練り羽根１０が、軸１１で回転自在に軸支され、モータ６により回転される。１２はヒータ３やモータ６への通電を制御する制御装置である。
【０００５】
以上のように構成されたパン製造機について、以下その動作を説明する。パン容器９にパン材料を入れ運転すると、ヒータ３、モータ６を制御し、パン生地の混練工程、発酵工程、ガス抜き工程を順次行い、最後に焼成室４内を１５０〜２００℃の高温に加熱し、パンを焼き上げる焼成工程を行う。製パン工程はパンの種類等によって差があり、前記工程全体で約２〜７時間程度の時間を要する。レーズン、ナッツ類、チーズ等の製パン副材料を加えたレーズンパン、ナッツパン、チーズパン等をつくる場合には、パン容器９に小麦粉、水、バター、砂糖、塩、イースト等の製パン主材料と共に運転当初から、前記製パン副材料を入れて前記の製パン工程を運転していた。
【０００６】
また機器によっては、約２０分程度のパン材料の混練工程のうち約１７分間程度を経過した時点で、使用者に製パン副材料投入の時期の報知を行い、使用者が自分で副材料の投入を行い、その後残り約３分間の混練により製パン主材料と副材料の混合を行っていた。
【０００７】
特許文献１は前述のパンの焼成工程を基本とし、さらに利便性の向上と仕上がりの多様化を図るためにパンの焼成工程と異なる時点で副材料を投入できるようにしている。以下、図１０を用いて副材料の投入構成について説明する。
【０００８】
図１０（ａ）は蓋容器の着脱構成を示したものである。図に示すように副材料投入手段には、投入する製パン副材料を収容する蓋容器１３と、蓋容器１３の底を開閉する開閉板１４と、製パン副材料をセットする際に蓋容器１３上方を開閉する容器蓋２０とを有し、蓋容器１３と開閉板１４を同期させ蓋容器１３を容器軸１５を支点として傾けることによりパン容器９に製パン副材料を投入するものであり、確実で正確にパン容器９内に製パン副材料を投入できる。また、蓋容器１３を樹脂製とすれば、蓋容器１３の温度上昇を抑制することができ、火傷を防ぎ安全性を向上することが出来る。
【０００９】
また、図１０（ｂ）は蓋容器の動作機構を示したもので、図に示すように、副材料の投入は、ソレノイド１６によりレバー１７を介して軸レバー１８を押し、焼成室３に開閉板１４を開いて、容器軸１５を中心に蓋容器１３を開閉板１４と同様に傾けることにより行う。これにより蓋容器１３内の副材料１９は、滑り台状に蓋容器１３上をすべりパン容器９内へ投入される。蓋容器１３は傾く際、パン容器９に近づき、また滑り台上に副材料が滑っていくため、副材料１９がパン容器９の外へ飛び散ることなく投入が行えるというものであった。

【発明が解決しようとする課題】
しかしながら前記従来の構成では、パンの焼成中に高温の排気が容器蓋２０側に排出されないようにするために副材料の投入後は開閉板１４を閉塞する必要があるが、滑り台状の面が完全に閉塞されず、開閉板１４の周囲に隙間が生じることがあった。また、容器蓋２０と蓋容器１３あるいは蓋８の間も、完全なシールが為されておらず隙間が開いているため、パン焼成中の蒸気を含んだ高温の排気が容器蓋２０の周囲から洩れ出し、その近傍に結露が生じていた。さらに、うっかり使用でパン容器９のセットを忘れて空焼き運転すると、容器蓋２０周囲から洩れる排気がさらに高温になり、容器蓋２０周囲の蓋８が熱変形することがあった。
【００１２】
また、蓋容器１３の内壁が平面で形成されているため、洋酒漬けのレーズンやバナナ等の粘着性の強い副材料を使用すると、副材料が内壁面にくっついてしまい、開閉板１４を開放しても副材料が落ちきらず、蓋容器１３内に残ることがあった。さらに、副材料を入れて蓋容器１３の持ち運びをすると、投入側が開口されており完全なる容器の形ではないので、収容物をこぼしやすいという課題があった。
【００１３】
また、蓋容器１３は副材料の引掛り防止や容量、収納性確保のため、凹凸形状を形成することができず、着脱時の摘み形状が設けられていないので、着脱操作性が悪かった。特に、蓋容器１３中に副材料を入れた状態では着脱操作性が悪く、副材料をこぼさずに蓋容器１３を着脱することは困難であった。
【００１４】
本発明は前記従来の課題を解決するもので、蓋容器およびその周辺の構成を工夫することにより、排気の漏出による結露や熱変形の防止、または機能の向上を図り利便性をよくしたパン製造機を提供することを目的とする。
【００１５】
【課題を解決するための手段】

【００１６】
この構成により、前記蓋と前記容器蓋とをロックすることで、前記蓋容器と容器蓋との間に設けたパッキンが押圧され確実にシールすることができ、排気が外部に漏出するのを実質的に防止することができる。また、蓋を開いても容器蓋が開くことがないため、副材料のこぼれや蓋容器の落下を防止することができる。

【００４１】
請求項２４に記載の発明は、蓋容器に回動自在に取り付けられる係止部材の一端に投入手段である開閉板を係止する爪を形成し、その先端に凸部を設けることにより、開閉板に開く方向の荷重がかかり、開閉板が係止部材の爪を下方に押して、係止部材が回動しようとしても、凸部が開閉板に当接し、それ以上回動できないため、開閉板が不用意に開くのを防止することができる。
【００４２】
【実施例】
以下、本発明の実施例について、図面を参照しながら説明する。
【００４３】
（実施例１）

【００４４】
図１〜６において、２１は板金で形成した本体、２２は本体２１に取付けられたシャーシで、このシャーシ２２にはモータ２３と焼成室２４と容器取付台２５が取り付けられている。また、焼成室２４の内部には、パン材料がセットされる着脱自在なパン容器２６と、ヒータ２７と、焼成室２４内の温度を検知する温度検知部２８が設けられている。さらに、パン容器２６には、パン材料を混練する練り羽根２９と、練り羽根２９が嵌合されベルト３０を介しモータ２３によって回転する回転軸３１と、パン容器２６の着脱時や持ち運び時に握る把手３２を備えている。
【００４５】
また、３３は内蓋３４と焼成室２４内の蒸気を外気へ排出する排気ダクト３５を具備し、焼成室２４を開閉する蓋である外蓋で、本体２１に回動自在に取り付けられている。３６はレーズンやナッツ等の製パン副材料を収納する蓋容器で、パン容器２６上方の外蓋３３内部に着脱自在に配設され、蓋容器３６の外周には蓋容器３６が載置される蓋容器載置部材３７が配設されている。３８は蓋容器３６に回動自在に取り付けられ、蓋容器３６下方の開口部を開閉する投入手段である開閉板で、表面に製パン副材料が付着しないよう、複数の凹凸部３９を形成し、その上にフッ素加工を施している。４０は開閉板３８を係止する係止部材で、蓋容器３６に回動自在に取着され、一端には開閉板３８に形成された角孔４１に係合される爪４２が形成されている。４３は爪４２の先端に形成された凸部、４４は係止部材４０の爪４２を角孔４１に係合させる方向に附勢するバネＡ、４５は外蓋３３の内部に摺動自在に取り付けられた蓋レバーで、製パン副材料投入時に摺動し係止部材４０の一端を押圧して開閉板３８を開くもので、通常はバネＢ４６の附勢により蓋容器載置部材３７の内部に引っ込んでいる。７２は指が収まる大きさの凹形状に形成された摘み部、７３は摘み部７２の開口部側方に形成され、指で摘む際の滑り止めになるリブ、６６は係止部材４０を蓋容器３６に回動自在に取り付ける板バネで、一端には蓋容器載置部材３７に係止される係止部６７が一体的に形成されている。６８は蓋容器載置部材３７に設けられ、係止部６７が嵌合する被係止部、６９は板バネ６６や係止部材４０の周囲を囲むように形成したリブまたは壁で、係止部材４０、摘み部７２、板バネ６６はいづれも蓋容器３６右側の同一側面に配されている。
【００４６】
また、４７は外蓋３３に回動自在かつ着脱自在に取り付けられ、蓋容器３６を開閉する容器蓋で、耐熱性の高い材料で形成され直接蓋容器３６上方の開口部を開閉する中蓋４８と、ピアノ線などの線材で形成され中蓋４８を可動自在に取着する複数の固定部材４９と、マグネット金具Ａ５０と、円形軸の両側をＤカットして形成した複数のヒンジ５１を具備している。
【００４７】
また、中蓋４８は蓋容器載置部材３７上面の内周全周に突設されたリブ５２と当接するとともに、外周に耐熱性の高いシリコンゴムで形成したパッキン５３が装着されており、中蓋４８を閉じるとパッキン５３が蓋容器載置部材３７の上面に押圧され、蓋容器３６上方の開口部はシールされ完全密閉される。５４は容器蓋４７に複数設けられ固定部材４９が取り付けられる固定リブ、５５は中蓋４８に複数設けられ固定部材４９に嵌合される引掛爪で、固定部材４９や容器蓋４７との間に少量の隙間を設けることにより、中蓋４８に前後左右上下方向のあそびを持たせ、可動自在に容器蓋４７へ取着している。
【００４８】
また、５６は容器蓋４７を開く際に容器蓋４７を指で摘みやすいよう、外蓋３３の天面左端に形成されたへこみ部、５７は容器蓋４７の開閉時に摘む操作部、５８と５９は外蓋３３と蓋容器載置部材３７に挟持されて固定されたマグネットとマグネット金具Ｂで、ヒンジ５１と操作部５７の間に配設され、マグネット金具Ｂ５９のみ端面が外蓋３３を貫通して外に露出し、マグネット金具Ａ５０をマグネット５８の磁力で吸着している。またパッキン５３は、容器蓋４７のロック手段を構成するマグネット金具Ａ５０、マグネット金具Ｂ５９、マグネット５８と、ヒンジ５１の間に配設される。
【００４９】
また、６０は外蓋３３に設けられ容器蓋４７のヒンジ５１が取り付けられる凹部で、上方には開口部６１が設けられ、容器蓋４７を所定の角度まで開いて手前に引くと、外蓋３３から取り外せるようになっている。６２は製品正面に向かって右側に配され、メニューの選択や調理のスタート等を行う操作部材、６３は操作部材６２に取り付けられ蓋レバー４５を押圧して開閉板３８を開くソレノイド、６４は蓋レバー４５を押圧するソレノイド６３の摺動部材を操作部材６２の内部に収納する方向に附勢するバネＣ、６５はモータ２３、ヒータ２７、ソレノイド６３の通電を制御し、温度検知部２８により検知された温度情報に基づいて、予熱、混練、発酵、焼成等の製パン工程を自動的に行う制御手段である制御装置である。
【００５０】
以上のように構成されたパン製造機について、以下にその動作と作用を説明する。レーズンやナッツ等の副材料を使ってパンを焼き上げる場合、まず小麦粉、イースト、砂糖、塩、ドライミルク、バター、水等の製パン基本材料をパン容器２６中に入れ、このパン容器２６を焼成室２４内の容器取付台２５にセットして外蓋３３を閉じた後、図６の（ａ）、（ｂ）に示すように容器蓋４７を開き、レーズンやナッツ等の製パン副材料を蓋容器３６に入れて容器蓋４７を閉じる。この時、爪４２の先端に凸部４３を設けることにより、開閉板３８に副材料の重量やセット時の押圧力がかかり、爪４２上面に下方の押圧力がかかっても、凸部４３が角孔４１に掛かり爪４２が角孔４１から抜けにくいため、開閉板が誤って開くのを防止することができる。
【００５１】
次に、副材料を使うパンのメニューを操作部材６２上のキーを押して選択しスタートキーを押すと、製パン基本材料を所定の温度に保つ予熱工程を経て、練り羽根２９が間欠回転し基本材料を混練する混練工程が始まる。混練が進みパン生地が形成されると、練り羽根２９の回転が止まりソレノイド６３に例えば１．５秒間通電され、ソレノイド６３の摺動部材が側方に突出し、蓋レバー４５を介して係止部材４０の一端を押圧する。すると、係止部材４０が回動して爪４２が角孔４１から引き抜かれ、開閉板３８が自重と副材料の重量によって開き、副材料が蓋容器３６下方のパン容器２６中に投入され、再度混練工程が始まり副材料がパン生地中に均一に練り込まれる。
【００５２】
その後、開閉板３８が開いた状態のまま発酵工程、焼成工程を経てパンが焼き上がるが、蓋容器３６上方の開口部を開閉する中蓋４８に、弾性を有し耐熱性の高いシリコンゴムで形成したシール用のパッキン５３を装着するとともに、マグネット５８によりマグネット金具Ａ５０をマグネット金具Ｂ５９に吸着させて、容器蓋４７と中蓋４８の開閉をロックすることにより、パッキン５３をシール面を構成する蓋容器載置部材３７の上面に押圧し、パッキン５３のリップをたわませながら蓋容器載置部材３７上面に圧接した状態で、容器蓋４７と中蓋４８をロックできるため、シール面の位置が多少ばらついてもリップのたわみ代で吸収し蓋容器３６外周と中蓋４８の間をパッキン５３で実質的にシールすることができ、外蓋３３や容器蓋４７の結露や熱変形を防止することができる。
【００５３】
なお、ここで言う「実質的にシールする」とは確実にシールすること、または、パッキンの一部から微量の排気が漏出しても結露が生じたり、蓋などの構成材料が熱変形したりするような損傷を起こさないような程度のシールを言う。
【００５４】
上述の説明では、容器蓋４７に取り付けられる別部材の中蓋４８に、パッキン５３を装着した実施例を示したが、中蓋４８をなくし容器蓋４７を耐熱性の高い材料で形成して、パッキン５３を直接容器蓋４７に装着してもよく、上記と同様な効果を得ることができる。また、本実施例では蓋容器３６を着脱自在な構成にしているが、蓋容器３６を固定した構成にしても、同様の効果を得ることができる。なお、この場合は蓋容器載置部材を用いなくても良い。
【００５５】
また、パッキン５３をロック手段を構成するマグネット金具Ａ５０とヒンジ５１の間に配設することにより、てこの原理からマグネット５８の吸着力より強い力で、パッキン５３をシール面の蓋容器載置部材３７上面に押圧することができるとともに、ロック手段を構成するマグネット金具Ａ５０、マグネット５８をヒンジ５１と操作部５７、へこみ部５６の間に配設することにより、上記と同様にマグネット５８の吸着力より弱い操作力で容器蓋４７を開閉できる。すなわち、パッキン５３をシール部に強く押圧しながら、容器蓋４７の開閉操作力はそれより軽くできるため、シール性を高めつつ容器蓋４７の軽い開閉操作性を実現できる。
【００５６】
なお、前記実施例ではロック手段をマグネット金具Ａ５０とマグネット金具Ｂ５９およびマグネット５８で構成していたが、ロック手段はこれに限らず、テレビなどの調整つまみの隠し扉などのロックに使われている浮き出しラッチを使っても良い。また、ロック手段に蝶ねじを使っても良い。つまり、外蓋３３に蝶ねじを取付け、容器蓋４７に蝶ねじの表面形状に合わせた孔を形成して、蝶ねじをねじって孔に合わせれば容器蓋４７を開くことができ、蝶ねじをねじって孔形状からずらせば容器蓋４７をロックできる。あるいは写真立て裏面の衝立のロック手段に使われているような回動自在な係止部材を外蓋３３に設けて容器２７のロック手段を構成してもよい。この他、ガラス扉に用い２枚のガラス扉を固定する回転レバー方式のロック手段を用いても良い。

また、パッキン５３を容器蓋４７と別部材の中蓋４８に装着し、この中蓋４８を容器蓋４７に前後左右上下方向に可動自在に取り付けることにより、シール面を構成する蓋容器載置部材３７上面の平面度や寸法、あるいは組立状態がばらついてシール面の位置が変化しても、中蓋４８は自重とマグネット５８の吸着力によりシール面に沿って載置押圧されるため、実質的にシール性を維持することができる。ここで言う実質的とは先に述べたと同様、確実または実質的に周囲に損傷を与えないシールを言う。さらに、開閉板３８の開放時、高温にさらされる蓋容器３６上方の部位を、別部材の中蓋４８で構成することにより、容器蓋４７はコストの高い高耐熱性の材料を使用する必要がなくなるとともに、外郭を構成する容器蓋４７の表面温度が下がるため、コストダウンと安全性の向上を図ることができる。
【００５８】
また、パッキン５３を中蓋４８の外周に装着できるため、容器蓋４７の中央部に装着するより組立性も向上できる。以上述べたように、パッキン５３の設け方としては容器蓋４７に、または中蓋に、あるいは容器蓋４７と中蓋とに設けるいずれの方法であっても良い。
【００５９】
さらに、容器蓋４７の左右にピアノ線などの線材から形成した固定部材４９を取り付け、この固定部材４９に中蓋４８の左右に設けた引掛爪５５を係合することにより、中蓋４８の取り付け用のねじが不要になり、容器蓋４７と固定部材４９は高耐熱性樹脂で形成された中蓋４８で遮熱され、高温になることはないため、固定部材４９に中蓋４８の自重等の荷重がかかっても、容器蓋４７に熱変形や熱劣化等の異常が生じるのを防ぐことができ、中蓋４８を容器蓋４７に可動自在に取り付けることができるので、耐熱性に対する信頼性を確保しながら、シール性を確実に維持することができる。
【００６０】
また、着脱自在な蓋容器３６が載置されその外周に配設された蓋容器載置部材３７の内周上方にリブ５２を突設し、中蓋４８とリブ５２がパッキン５３の内側で全周に渡り実質的に当接するように配設することにより、蓋容器３６のセットをうっかり忘れても、容器蓋４７を閉じていれば中蓋４８とリブ５２がパッキン５３の内側で全周に渡り実質的に当接するため、開閉板３８を開放して蓋容器３６上方が高温にさらされても、その熱をパッキン５３の内側で遮熱することができ、さらにその外側もパッキン５３でシールされるため、蓋容器載置部材３７近傍の外蓋３３や容器蓋４７の熱変形を防止することができる。
【００６１】
また、パッキン５３の内側に設けたリブ５２が中蓋４８に当接しているため、高温の水蒸気がパッキン５３の位置まで到達し難く、パッキン５３にかかる熱負荷を軽減しパッキン５３の熱劣化や熱老化も防止することができる。なお、ここで言う実質的とは、例え一部分が当接していなくても全周が当接している場合とほぼ同じ機能を有するという事を意味する。
【００６２】
さらに、パッキン５３は蓋容器３６にまたがることなく、その外周の蓋容器載置部材３７上面に当接させてシールするよう構成することにより、蓋容器３６のセットをうっかり忘れてもシール状態は変わらず、同じシール性を維持することができるため、蓋容器載置部材３７近傍の外蓋３３や容器蓋４７の熱変形を防止することができる。
【００６３】
図７は焼成工程における温度検知部温度の経時変化を表したグラフである。図に示すように、焼成室２４内の温度を検知する温度検知部２８を具備し、パンの焼成工程において、温度検知部２８の温度が６０℃から９０℃まで上がるのに要した時間が、設定時間ｔより短い場合はヒータ２７への通電を止め、設定時間ｔ以上の場合はヒータ２７への通電を継続するように制御するプログラムにしている。そして、この設定時間ｔを通常使用時の所要時間ｔ２より短く、かつパン容器２６や蓋容器３６のセット忘れ等のうっかり使用による空焼き時の所要時間ｔ１より長く設定することにより、うっかり使用による空焼き運転をしてしまった場合でも、温度検知部２８の温度上昇勾配が高くなり、６０℃から９０℃まで上昇するのに要する所要時間が設定時間ｔより短くなるため、空焼き等の異常使用として検知しヒータ２７への通電を止めることができる。このため各部の異常温度上昇による熱変形等の製品の損傷や故障を防止することができる。
【００６４】
なお、上記実施例では温度上昇勾配を６０℃から９０℃までの間で検知させているが、これはこの間の温度上昇が外的要因によるばらつきが生じにくく安定しているためで、この温度上昇勾配を検知する範囲は、本体構成に合わせて最適な範囲に設定するものであり、固定的なものでないことは言うまでもない。また、設定時間ｔも同様に、本体構成によって変わるものである。
【００６５】
また、開閉板３８を係止する係止部材４０と摘み部７２を、蓋容器３６の同一側面側に集約して配することにより、蓋容器３６のデッドスペースの発生を最小限に抑え、蓋容器３６の大容量化を図ることができるとともに、係止部材４０に付随する部品が摘み部７２側に集約され、蓋容器３６は摘み部７２側の重量が重くなるため、重量の重い側を摘むことができ良好な着脱操作性を確保することができる。
【００６６】
また、係止部材４０を駆動するソレノイド６３を操作部材６２の内部に配設し、係止部材４０と摘み部を操作部材６２側に配設することにより、係止部材４０とソレノイド６３を最短距離で配することができるため、それらの間に介在して駆動力を伝達する部品の小型化が図れるとともに、係止部材４０と開閉板３８の動作の信頼性を高めることができる。
【００６７】
さらに、蓋容器３６と操作部材６２が近接し、操作部材６２を製品正面に向かって右側に配することにより、蓋容器３６の摘み部７２も製品正面に向かって右側に配されるため右手で摘みやすく、また蓋容器３６の着脱操作と操作部材６２の操作を、使用者が手をあちこちに動かさなくても、一連の流れるような動作で行うことができ、着脱操作性を良くすることができる。
【００６８】
また、蓋容器３６上面に形成した凹部で摘み部７２を構成し、摘み部７２の側方上端にリブ７３を設けることにより、摘み部７２が摘みやすいとともに、摘み部７２を摘んだ際に指がリブ７３に掛かるため、滑りにくく着脱操作性を向上することができる。また、リブ７３により摘み部７２の側方上端の剛性が上がるため、強度を向上し摘み部７２の破損を防止することもできる。
【００６９】
さらに、係止部材４０を板バネ６６を介して蓋容器３６に回動自在に取り付け、蓋容器載置部材３７に係止される係止部６７を前記板バネ６６に形成するとともに、板バネ６６や係止部材４０の周囲を蓋容器３６に形成したリブ６９で囲んで構成することにより、板バネ６６だけで係止部材４０の固定と蓋容器３６の蓋容器載置部材３７への固定を行うことができるため、部品点数を削減し安価に製品を提供することができる。
【００７０】
また、係止部材４０を介して蓋容器３６は蓋容器載置部材３７に係止されるため、容器蓋４７を開いたまま外蓋３３を開いても蓋容器３６が落下することはなく、蓋容器３６の破損や床面の傷付きを防ぐことができる。さらに、板バネ６６や係止部材４０の端面が露出するのを防止できるため、お手入れ時に手やスポンジたわし等が板バネ６６や係止部材４０の端面に触れるのを防ぎ、けがの発生や部品の変形破損を防止でき、安全性の確保と信頼性の向上を図ることもできる。
【００７１】
なお、本実施例では板バネ６６で係止部材４０と蓋容器３６の固定を行っているが、それに加えて板バネ６６で係止部材４０の附勢を行ってもよい。すると、バネＡを廃止することもでき、さらに部品点数や組立工数を削減し、コストダウンや信頼性向上を図ることができる。
【００７２】
また、蓋容器３６に回動自在に取り付けられる係止部材４０の一端に開閉板３８を係止する爪４２を形成し、その先端に凸部４３を設けることにより、レーズン等の製パン副材料をセットする際や外蓋３３を閉じる際に、開閉板３８に開く方向の荷重や衝撃がかかり、開閉板３８の角孔４１端面が爪４２上面を下方に押し、係止部材４０が回動しそうになっても、凸部４３が角孔４１上方の開閉板３８に当接し、それ以上回動できないため、開閉板３８が不用意に開くのを防止することができる。
【００７３】
（実施例２）
図８は本発明の実施例２におけるパン製造機の蓋容器の平面図である。なお、本実施例の基本構成は実施例１と同じなので異なる点を中心に説明する。また、実施例１と同じ機能には同じ符号を付しその説明は省略する。図において、７０はレーズンやナッツ等の製パン副材料を収納する蓋容器で、外蓋３３内部に着脱自在に配設され、複数の凹凸部３９を有するフッ素加工を施された回動自在な開閉板３８を備えている。また、蓋容器７０は副材料が接触する内壁を縦方向の複数の曲面７１で形成され、指が収まる大きさに形成された摘み部７２と、指で摘む際の滑り止めとなるリブ７３が設けられている。
【００７４】
以上のように本実施例では、蓋容器７０の内壁を複数の曲面で形成し、開閉板３８の表面に複数の凹凸部３９を設けることにより、副材料との密着面積を小さくすることができるため、粘着性の強い副材料を使用しても広い平面で密着することがなく、蓋容器７０の内壁や開閉板３８の表面に付着しにくく、材料残りを防止することができる。なお、蓋容器７０の内壁は、曲面の代わりに多数の凹凸形状またはシボ加工で形成しても、副材料との密着面積を小さくすることができるため、上記と同様に材料残りを防止することができる。
【００７５】
【発明の効果】
以上のように請求項１ないし７、９ないし１６に記載の発明によれば、製パン副材料を自動投入するための蓋容器を設けた焼成室を開閉する蓋や、容器蓋への結露やその熱変形を防止できる。請求項８、１７ないし２４に記載の発明によれば、さらに蓋容器およびその周辺の機能を向上し、利便性を良くすることができる。

[0003]
As this type of bread making machine, for example, there is one as described in Patent Document 1. FIG. 9 is a cross-sectional view of a conventional bread maker described in Patent Document 1.
[0004]
In FIG. 9, a chassis 2 provided in a main body 1 has a baking chamber 4 containing a heater 3 as a heating means built in its upper part and is fixed by a bread container mounting base 5, and a motor 6 is installed in the lower part. It is fixed. The chassis 2 has a sheet metal body 1 sandwiched and fixed by a bottom plate 7 at the lower end. Reference numeral 8 denotes an outer lid for opening and closing the baking chamber 4. The bread container 9 is detachably mounted on the bread container mount 5, and a kneading blade 10 as a kneading means is rotatably supported by a shaft 11 at the center bottom in the bread container 9. It is rotated by the motor 6. Reference numeral 12 denotes a control device that controls energization to the heater 3 and the motor 6.
[0005]
The operation of the bread maker configured as described above will be described below. When the bread ingredients are put into the bread container 9 and operated, the heater 3 and the motor 6 are controlled, the dough kneading process, the fermentation process, and the degassing process are sequentially performed, and finally the inside of the baking chamber 4 is heated to a high temperature of 150 to 200 ° C. And baking process for baking bread. The bread making process varies depending on the type of bread and the like, and the entire process takes about 2 to 7 hours. When making raisin bread, nut bread, cheese bread, etc. with bread making ingredients such as raisins, nuts, cheese, etc., the main ingredients of bread making such as flour, water, butter, sugar, salt, yeast in the bread container 9 In addition, from the beginning of the operation, the bread making process was performed by adding the bread making auxiliary material.
[0006]
Also, depending on the equipment, when about 17 minutes of the kneading process of bread material takes about 20 minutes, the user is notified of the timing of adding the bread making auxiliary material, and the user himself / herself selects the auxiliary material. After that, the bread making main material and the auxiliary material were mixed by kneading for the remaining 3 minutes.
[0007]
Patent Document 1 is based on the bread baking process described above, and in order to further improve convenience and diversify the finish, it is possible to add auxiliary materials at a different point from the bread baking process. In the following, the auxiliary material charging configuration will be described with reference to FIG.
[0008]
FIG. 10A shows a configuration for attaching and detaching the lid container. As shown in the figure, in the auxiliary material input means, the lid container 13 for storing the bread baking auxiliary material to be input, the opening / closing plate 14 for opening and closing the bottom of the lid container 13, and the lid container for setting the bread baking auxiliary material 13 has a container lid 20 that opens and closes, and the lid container 13 and the opening / closing plate 14 are synchronized, and the lid container 13 is tilted with the container shaft 15 as a fulcrum to feed the bread making material into the bread container 9.

[Problems to be solved by the invention]
However, in the above-described conventional configuration, it is necessary to close the opening / closing plate 14 after the addition of the secondary material in order to prevent high temperature exhaust from being discharged to the container lid 20 side during baking of the bread. In some cases, the opening / closing plate 14 was not completely closed and a gap was generated around the opening / closing plate 14. In addition, since the gap between the container lid 20 and the lid container 13 or the lid 8 is not completely sealed and a gap is opened, high-temperature exhaust gas containing steam during baking is discharged from around the container lid 20. Leakage occurred and dew condensation occurred in the vicinity. Furthermore, if the baking container 9 is forgotten to be set inadvertently and the baking operation is performed, the exhaust leaking from the periphery of the container lid 20 becomes further hot, and the lid 8 around the container lid 20 may be thermally deformed.
[0012]
Further, since the inner wall of the lid container 13 is formed as a flat surface, if a highly adhesive secondary material such as raisin or banana pickled in sake is used, the secondary material sticks to the inner wall surface, and the opening / closing plate 14 is opened. However, the secondary material may not fall down and may remain in the lid container 13. Further, when the lid material 13 is carried with the auxiliary material put therein, there is a problem that the contents are easily spilled because the inlet side is opened and is not in the form of a complete container.
[0013]
Further, the lid container 13 could not be formed with a concave / convex shape in order to prevent the secondary material from being caught, to ensure the capacity and the storage property, and since the knob shape at the time of attachment / detachment was not provided, the attachment / detachment operability was poor. In particular, when the secondary material is put in the lid container 13, the detachability is poor, and it is difficult to attach and detach the lid container 13 without spilling the secondary material.
[0014]
SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems. By contriving the lid container and its surrounding structure, it is possible to prevent dew condensation and thermal deformation due to leakage of exhaust gas, or to improve functions and improve convenience of bread production. The purpose is to provide a machine.
[0015]
[Means for Solving the Problems]

It is a control device which is a control means for automatically performing bread making processes such as preheating, kneading, fermentation and baking based on the temperature information.
[0050]
The operation and action of the bread maker configured as described above will be described below. When baking bread using raisins, nuts and other secondary ingredients, first put basic ingredients for bread making, such as flour, yeast, sugar, salt, dry milk, butter, water, etc. into the bread container 26, and the bread container 26 is baked. After setting the container mounting base 25 in the chamber 24 and closing the outer lid 33, the container lid 47 is opened as shown in FIGS. 6 (a) and 6 (b), and the bread-making auxiliary materials such as raisins and nuts are added. The container lid 47 is closed in the lid container 36. At this time, by providing the convex portion 43 at the tip of the claw 42, the weight of the auxiliary material and the pressing force at the time of setting are applied to the opening / closing plate 38. Since the claw 42 is not easily pulled out from the square hole 41 by engaging with the square hole 41, the opening / closing plate can be prevented from being opened accidentally.
[0051]
Next, when the menu of the bread using the secondary material is selected by pressing the key on the operation member 62 and the start key is pressed, the kneading blade 29 is intermittently rotated through a preheating process for keeping the basic baking material at a predetermined temperature. The kneading process for kneading the materials begins. When the kneading progresses and bread dough is formed, the rotation of the kneading blades 29 stops and the solenoid 63 is energized for, for example, 1.5 seconds, the sliding member of the solenoid 63 protrudes to the side, and the locking member 40 is connected via the lid lever 45. Press one end of the. Then, the locking member 40 is rotated, the claw 42 is pulled out from the square hole 41, the opening / closing plate 38 is opened by its own weight and the weight of the subsidiary material, and the subsidiary material is put into the bread container 26 below the lid container 36, The kneading process begins again, and the auxiliary material is uniformly kneaded into the bread dough.
[0052]
After that, the bread is baked through the fermentation process and the baking process with the open / close plate 38 opened, but the inner lid 48 that opens and closes the opening above the lid container 36 is made of silicon rubber having elasticity and high heat resistance. The formed seal packing 53 is attached, and the magnet fitting A50 is attracted to the magnet fitting B59 by the magnet 58 to lock the opening and closing of the container lid 47 and the inner lid 48, thereby forming the sealing surface of the packing 53. Since the container lid 47 and the inner lid 48 can be locked in a state where the container lid 47 is pressed against the upper surface of the lid container placement member 37 and pressed against the upper surface of the lid container placement member 37 while the lip of the packing 53 is bent, the position of the sealing surface Even if there is some variation, it can be absorbed by the bending allowance of the lip, and the gap between the outer periphery of the lid container 36 and the inner lid 48 can be substantially sealed by the packing 53, and the outer lid 33 and the container lid 4 It is possible to prevent condensation and thermal deformation.
[0053]
Note that “substantially seal” as used herein means that sealing is performed reliably, or even if a small amount of exhaust gas leaks from a part of the packing, condensation occurs, or the constituent materials such as the lid are thermally deformed. A seal that does not cause such damage.
[0054]
In the above description, an example in which the packing 53 is attached to the inner lid 48 of another member attached to the container lid 47 is shown, but the inner lid 48 is eliminated and the container lid 47 is formed of a material having high heat resistance, The packing 53 may be directly attached to the container lid 47, and the same effect as described above can be obtained. In this embodiment, the lid container 36 is detachable. However, the same effect can be obtained even when the lid container 36 is fixed. In this case, the lid container placing member may not be used.
[0055]
Further, by arranging the packing 53 between the magnet fitting A50 constituting the locking means and the hinge 51, the packing 53 is attached to the cover container mounting member on the sealing surface with a force stronger than the attracting force of the magnet 58 from the principle of leverage. 37, the magnet bracket A50 and the magnet 58 that constitute the locking means can be pressed between the hinge 51, the operation portion 57, and the dent portion 56, so that the attracting force of the magnet 58 is the same as described above. The container lid 47 can be opened and closed with a weaker operating force. That is, since the opening / closing operation force of the container lid 47 can be made lighter while strongly pressing the packing 53 against the seal portion, it is possible to realize a light opening / closing operation of the container lid 47 while improving the sealing performance.
[0056]
In the above embodiment, the locking means is composed of the magnet fitting A50, the magnet fitting B59, and the magnet 58. However, the locking means is not limited to this, and is used for locking a hidden door of an adjustment knob of a television or the like. A raised latch may be used. Moreover, you may use a thumbscrew for a locking means. That is, by attaching a butterfly screw to the outer lid 33 and forming a hole in the container lid 47 in accordance with the surface shape of the butterfly screw, the container lid 47 can be opened by twisting the thumbscrew to match the hole. The container lid 47 can be locked by twisting it out of the hole shape. Alternatively, the locking means for the container 27 may be configured by providing the outer lid 33 with a pivotable locking member used for the screen locking means on the back of the photo frame. In addition, you may use the locking means of a rotation lever system used for a glass door and fixing two glass doors.
[0057]
Further, the packing 53 is attached to the inner lid 48 which is a member separate from the container lid 47, and the inner lid 48 is attached to the container lid 47 so as to be movable in the front / rear, left / right and up / down directions. 37 Even if the flatness and dimensions of the upper surface or the assembly state vary and the position of the seal surface changes, the inner lid 48 is placed and pressed along the seal surface by its own weight and the attractive force of the magnet 58, so The sealing property can be maintained. As used herein, substantially refers to a seal that is reliably or substantially undamaged around as described above. Furthermore, when the opening / closing plate 38 is opened, the portion above the lid container 36 that is exposed to a high temperature is configured with the inner lid 48 of another member, so that the container lid 47 needs to use a high-heat-resistant material with high cost. In addition, since the surface temperature of the container lid 47 constituting the outer shell is lowered, the cost can be reduced and the safety can be improved.
[0058]
In addition, since the packing 53 can be attached to the outer periphery of the inner lid 48, the assemblability can be improved as compared with the case where the packing 53 is attached to the central portion. As described above, the packing 53 may be provided on the container lid 47, on the inner lid, or on the container lid 47 and the inner lid.
[0059]
Further, the fixing member 49 formed of a wire material such as a piano wire is attached to the left and right of the container lid 47, and the hooking claws 55 provided on the left and right of the inner lid 48 are engaged with the fixing member 49, thereby attaching the inner lid 48. No need for screws, and the container lid 47 and the fixing member 49 are shielded by the inner lid 48 formed of a high heat-resistant resin and do not become high temperature. Even when the load is applied, the container lid 47 can be prevented from being abnormally deformed or deteriorated, and the inner lid 48 can be movably attached to the container lid 47. As a result, the sealing performance can be reliably maintained.
[0060]
Further, a rib 52 is projected from the inner circumference of a lid container placement member 37 placed on the outer periphery of the lid container 36 which can be attached and detached, and the inner lid 48 and the rib 52 are all inside the packing 53. Even if the container lid 47 is inadvertently forgotten, the inner lid 48 and the ribs 52 are placed around the inner side of the packing 53 by closing the container lid 47 even if the lid container 36 is inadvertently forgotten. Even when the opening / closing plate 38 is opened and the upper portion of the lid container 36 is exposed to a high temperature, the heat can be shielded inside the packing 53, and the outside is sealed by the packing 53. Therefore, thermal deformation of the outer lid 33 and the container lid 47 in the vicinity of the lid container placement member 37 can be prevented.
[0061]
Further, since the rib 52 provided on the inner side of the packing 53 is in contact with the inner lid 48, it is difficult for high-temperature water vapor to reach the position of the packing 53, reducing the heat load applied to the packing 53, Heat aging can also be prevented. Note that the term “substantially” here means that even if a part is not in contact, it has substantially the same function as in the case where the entire circumference is in contact.
[0062]
Further, the seal 53 does not extend over the lid container 36 and is configured to be in contact with the upper surface of the lid container mounting member 37 on the outer periphery thereof so that the sealing state is changed even if the set of the lid container 36 is inadvertently forgotten. Therefore, since the same sealing performance can be maintained, thermal deformation of the outer lid 33 and the container lid 47 in the vicinity of the lid container placement member 37 can be prevented.
[0063]
FIG. 7 is a graph showing the change over time of the temperature detection part temperature in the firing step. As shown in the figure, a temperature detection unit 28 for detecting the temperature in the baking chamber 24 is provided, and in the baking process of bread, the time required for the temperature of the temperature detection unit 28 to rise from 60 ° C. to 90 ° C. The program is controlled to stop energization of the heater 27 when it is shorter than the set time t, and to continue energization of the heater 27 when it is longer than the set time t. Then, by setting this set time t shorter than the required time t2 for normal use and longer than the required time t1 for empty baking due to inadvertent use such as forgetting to set the bread container 26 or the lid container 36, it is caused by inadvertent use. Even if the air-burning operation has been performed, the temperature rise gradient of the temperature detection unit 28 becomes high, and the time required to rise from 60 ° C. to 90 ° C. is shorter than the set time t. It is detected that the heater 27 is used, and the heater 27 can be de-energized. For this reason, it is possible to prevent damage or failure of the product such as thermal deformation due to abnormal temperature rise of each part.
[0064]
In the above embodiment, the temperature rise gradient is detected between 60 ° C. and 90 ° C., but this is because the temperature rise during this period is less likely to vary due to external factors and is stable. It goes without saying that the range in which the gradient is detected is set to an optimum range in accordance with the main body configuration and is not fixed. Similarly, the set time t varies depending on the main body configuration.
[0065]
Further, by arranging the locking member 40 and the knob 72 for locking the opening / closing plate 38 together on the same side surface side of the lid container 36, the occurrence of dead space in the lid container 36 can be minimized, and the lid While the capacity of the container 36 can be increased, the parts associated with the locking member 40 are concentrated on the knob 72 side, and the lid container 36 is heavy on the knob 72 side. It can be picked and good detachability can be ensured.
[0066]
Further, the solenoid 63 for driving the locking member 40 is disposed inside the operation member 62, and the locking member 40 and the knob 63 are disposed on the operation member 62 side so that the locking member 40 and the solenoid 63 are shortest. Since they can be arranged at a distance, it is possible to reduce the size of parts that are interposed between them and transmit the driving force, and it is possible to increase the reliability of the operation of the locking member 40 and the opening / closing plate 38.
[0067]
Furthermore, since the lid container 36 and the operation member 62 are close to each other and the operation member 62 is arranged on the right side of the product front, the knob 72 of the lid container 36 is also arranged on the right side of the product front. It is easy to pick, and the attachment / detachment operation of the lid container 36 and the operation of the operation member 62 can be performed by a series of flowing operations without the user moving the hands around, improving attachment / detachment operability. it can.
[0068]
Further, the knob portion 72 is constituted by a concave portion formed on the upper surface of the lid container 36, and a rib 73 is provided at the upper side end of the knob portion 72, so that the knob portion 72 can be easily picked and fingers are picked when the knob portion 72 is picked. Since it hangs on the rib 73, it is difficult to slip and the detachability can be improved. Moreover, since the rigidity of the side upper end of the knob | pick part 72 goes up by the rib 73, intensity | strength can be improved and damage to the knob | pick part 72 can also be prevented.
[0069]
Further, the locking member 40 is rotatably attached to the lid container 36 via a plate spring 66, and a locking portion 67 to be locked to the lid container mounting member 37 is formed on the plate spring 66. 66 and the locking member 40 are surrounded by a rib 69 formed in the lid container 36, so that the locking member 40 is fixed and the lid container 36 is fixed to the lid container mounting member 37 only by the leaf spring 66. Therefore, the number of parts can be reduced and a product can be provided at low cost.
[0070]
Further, since the lid container 36 is locked to the lid container mounting member 37 via the locking member 40, the lid container 36 does not fall even if the outer lid 33 is opened while the container lid 47 is open. Breakage of the lid container 36 and damage to the floor surface can be prevented. Further, since it is possible to prevent the end surfaces of the leaf spring 66 and the locking member 40 from being exposed, it is possible to prevent hands and sponge scrubbing from touching the end surfaces of the leaf spring 66 and the locking member 40 during cleaning, Parts can be prevented from being deformed and damaged, ensuring safety and improving reliability.
[0071]
In this embodiment, the locking member 40 and the lid container 36 are fixed by the leaf spring 66, but in addition, the locking member 40 may be urged by the leaf spring 66. Then, the spring A can be abolished, the number of parts and the number of assembly steps can be reduced, and cost reduction and reliability improvement can be achieved.
[0072]
Further, a claw 42 for locking the opening / closing plate 38 is formed at one end of a locking member 40 that is pivotably attached to the lid container 36, and a convex portion 43 is provided at the tip thereof, thereby making a bread-making auxiliary material such as raisins. When setting the cover or closing the outer lid 33, a load or impact is applied to the opening / closing plate 38, the end face of the square hole 41 of the opening / closing plate 38 pushes the upper surface of the claw 42 downward, and the locking member 40 rotates. Even so, since the convex portion 43 abuts on the opening / closing plate 38 above the square hole 41 and cannot be rotated any further, it is possible to prevent the opening / closing plate 38 from being opened carelessly.
[0073]
