従来は、上部の米を貯留した貯留タンクから米の供給を受けて、洗米、水加減及び浸漬する洗米器の下側には炊飯器を設け、計量から炊飯までを行なう洗米炊飯機が一般的である。
【0003】
【発明が解決しようとする課題】
ところが、洗米器で洗浄終了後に投下する釜が準備されていないと、水を抜いた状態で洗米器内で保持するが、この状態で一定時間保持すると、洗浄済の米は洗米器3の内壁に貼り付いたり、またかたまったりして投下しにくくなる。
【0004】
【課題を解決するための手段】
この発明は、上記課題を解決する運転制御装置を提供するものであって、つぎのような技術的手段を講じた。すなわち、貯米タンク2と、この貯米タンク2内の米を所定量に計量供給されて洗米する洗米器3と、この洗米器3の下側に配置した炊飯器4とを備えた洗米炊飯機において、上記洗米器3内の洗米を下方の炊飯器4に投下する際洗米工程後の経過時間(T)が所定時間(T 0 )以上であるとの判定に基づいて投下準備工程に入り、この投下準備工程は、洗米器3内へ給水した後炊飯器4内に投下する構成とした洗米炊飯機における運転制御装置とした。
【0005】
【発明の作用】
洗米器3で洗浄終了後の洗米は釜の準備状況に応じて所定時間以上洗米器内へ保持される。炊飯器4への投下が可能となった際、洗米工程後所定時間以上を経過しているときは投下準備工程に入り、米は給水によって一旦ほぐされ、流動性をよくした後に投下される。
【0006】
【発明の効果】
この発明における洗米炊飯機における運転制御装置は、炊飯器4への投下が可能となった際、洗米工程後所定時間以上を経過しているときは投下準備工程に入り、米は給水によって一旦ほぐされ、流動性をよくした後に投下されるものであるから、米が洗米器の内壁にへばりついたり、かたまったりすることを防止できる。
【0007】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて具体的に説明する。まず、その構成について説明すると、白米を貯留、洗米及び炊飯する洗米炊飯機1を示すものであり、この洗米炊飯機1は、白米を貯留する貯米タンク2、白米の供給を受けて洗米、水加減及び浸漬する洗米器3、洗米済の白米を炊飯する炊飯器4が2台等によりなる状態を示したものである。
【0008】
機枠5の底部には、左右一対のガス釜を配設し、各ガス台6の上に各炊飯器4a,4bは外釜と、この外釜内に嵌合させた内釜8及び釜蓋9等を有し、該各ガス台6とともに前側に引き出しできるハンドル10を有し、これら炊飯器4a,4bの内釜8の着脱等は、前側へ引き出した位置で行なう構成としている。
【0009】
前記機枠5の上部後側に、左右水平状に上下にレ−ル11、12架設され、上部の貯米タンク2及び下部の洗米器3を有した移動台13がロ−ラ14a,14bによって移動自在に支持され、洗米器4a,4bの上側へ移動対向させて、洗米供給位置を切換自在にした構成としている。
【0010】
前記貯米タンク2は、下部に計量器15を有する。この計量器15は、欠円筒形態の回転筒を軸16の回りに計量モ−タ17で回転させて、該貯米タンク2に収容している米を一定量毎に回転しながら汲み出すもので、この軸16の回転数を回転センサ18で検出することにより、マイクロコンピュ−タを有する操作装置19の運転制御装置20のCPU21へ入力して計量(容量又は重量として)する構成としている。
【0011】
前記洗米器3は貯米タンク2の下側にあって、中央部に上下方向の撹拌軸22によって回転される撹拌棒23が、上部の洗米モ−タ24によってウォ−ムギヤ25等を介して伝動回転すべく設けられ、底部には、排出弁26によって開閉される排出口27が設けられている。この排出弁27は、撹拌軸22の中心部に沿って挿通させる弁軸28の下端部に一体で、弁軸28の上部には、排出モ−タ29によってクランク機構等を介して上下作動される構成としている。
【0012】
前記排出口27には、外周部に網30を介在させて排水室(A)31と連通させ、この排水室(A)31の排水弁32の開閉によって、水道水を下部ノズル33から洗米器3へ給水させたり、洗米後の排水を行なわせることができる。水道パイプから流量センサ34を経て誘導する給水パイプ35は、ソレノイドバルブ36によって開閉されて給水される下部ノズル33とソレノイドバルブ37とによって開閉されて給水されて給水される上部シャワ−38とを有し、洗米器3の上下部から洗米用および水加減用の給水を行い得る構成である。また、排水室(A)31の排水弁32は、ソレノイド39によってワイヤ40、ベルクランク41等を介して開閉作動される。41´は下給水バルブである。
【0013】
前記洗米器3は、貯米タンク2の前側よりに偏位させて、この後側部で洗米器3の下端部の排水室(A)42に連接の排水室(A)31を有し、この排水室(A)31は、上方部の貯米タンク2の下側域から外方へ突出しない形態としている。また、洗米器3の後側部には、移動台13をレ−ル11,12で支持する機枠5が設けられるが、この移動台13がレ−ル11,12に沿って左右方向へ移動するとき、排水室(A)31が機枠5に当たらないように設定している。
【0014】
前記貯米タンク2には蓋43が開閉自在に設けられ、米の供給充填を行なうことができる。また、この貯米タンク2の下部には、米の減少を検出して、米の補給をブザ−等で促すための米下限センサ44を有する。洗米器3の上部には、洗米水の満杯供給を検出する水上限センサ45を有し、また、これ以上の給水はオ−バ−フロ−口6から機外へ排水される。47は洗米器3の外周部を閉鎖する点検蓋である。
【0015】
前記移動台13は、貯米タンク2、洗米器3、計量器15、給水パイプ35およびこれらの計量モ−タ17、洗米モ−タ24、排出モ−タ29等を装着するほか、移動モ−タ48を有して、レ−ル11,12上を転動するロ−ラ14a,14bを駆動回転することによって横方向へ移動制御できる構成としている。
【0016】
前記操作装置19は箱型に形成して移動台13上の貯米タンク2の正面に装着しており、ON−OFFスイッチ方式の各種の操作手段類やLED表示部等が配置される。表示部49は、通常は時刻表示を行なうようになっているが、時刻以外の表示であるときに時刻表示に戻したいときは時計手段50を押せばよい。テスト手段51を押せば、表示部49の周囲に配置された各種表示ランプ、すなわち、操作手段番号で表示するヘルプ番号52、タイマ予約53、現在時刻54、貯米量55、累計釜数56、予約数57および貯米タンク2に対する米補給から炊飯完了に亘る各行程や残時間等を表示する行程表示58が順次表示される。
【0017】
また、計量手段59を押せば、計量モータ17が駆動され、計量器15が一回転される。洗米手段60を押せば、洗米モ−タ24が駆動されて、撹拌棒23が回転される。上給水手段61、下給水手段62等を押せば、各ソレノイドバルブ36,37等を開いて洗米器内へ給水を行なう。水位手段63を押せば、洗米器内の水位が水上限センサ45による検出時から水加減手段32の開きによって排水調整される。排水手段65を押せば、ソレノイド39の出力によって排水弁32を開いて、洗米じにおける汚水の排水を網30を通して行なわせる。
【0018】
投下手段66を押せば、排出モ−タ29を駆動して、排出弁26を開く。リセット手段67を押せば、表示部49のエラ−表示のフラグを解除できる。このようなテスト手段51〜リセット手段等は、主として始業前の点検を行なうときに操作する。
【0019】
設定手段としては、前記の水加減手段64の他に、炊飯量を設定する炊飯量手段68、洗米方法を設定する洗い方手段69、浸漬時間を設定する浸漬手段70、蒸らし時間を設定するむらし手段71、炊飯モ−ドを設定するモ−ド手段72、貯米タンク2に供給された米の量を設定する貯米手段73などを配置して、それぞれ炊飯前に適宜に設定しておくことができる。
【0020】
74は釜数を設定するための釜設定手段、75は計量器15の計量作動から開始させる始動手段、76は予約タイマを設定するタイマ設定手段、77は表示部49に表示される累計釜数をクリヤ−するクリヤ−手段、78は、エラ−ランプ79やブザ−80等で警報される故障箇所が不明なときに押すことによって、この故障箇所を番号によって表示させるためのヘルプ手段である。
【0021】
洗米、炊飯の作用行程は計量器15による計量→洗米器3よる洗米→洗米器における上部シャワ−38からの間歇的シャワ−による洗米部(ざる上げ)浸漬→洗米器3の移動台13の左、右移動→洗米器での水加減→排出弁26の開放による排米→炊飯器4aの内釜8での釜浸漬→ガス点火による炊飯→むらし→炊飯終了後の内釜交換の各工程を経る構成である。
【0022】
前記洗米器3が単一で左(L)、右(R)へ移動し、左、右二基の炊飯器4a,4bへ洗米を切換供給しながら炊飯する形態では、浸漬工程を、浸漬時間として浸漬手段70により適宜時間を設定することによって、各洗米工程と、各炊飯器4a,4bにおける炊飯工程とを連続させて、洗米から炊飯の全工程の効率的作業を行なわせることができる。各工程のうち、時間の変化されるものは、主として浸漬工程とむらし工程とであり、洗米部浸漬と釜浸漬との比を変更することができるようにしてもよい。該浸漬手段70による浸漬時間の設定は、CPU21で演算されて、洗米後の釜浸漬時間を算出制御する。この設定値に一致する浸漬時間となるように水加減が、ソレノイドバルブ36,37の出力によって開始されるが、このような水加減の開始は、洗米器3が炊飯器4a又は4bの上へ移動した後に行われる。
【0023】
すなわち、炊飯器4a,4bには、空の内釜8が備えられていることを検出する内釜センサ83、内釜上の釜蓋9の有無を検出する蓋センサ84、炊飯終了後に洗米器3が左・右移動して停止したことを検出する移動センサ85等によって、洗米器3による炊飯器4a又は4bに対する洗米の投下の用意が完了した状態位置で、洗米器における水加減が開始される。水加減が終了すると、排出モ−タ29の出力によって、排出弁26が開かれて、洗米を加減水とともに炊飯器4a又は4bへ排米投下し、前記演算された時間の釜浸漬が行われる。
【0024】
また、洗米が早く終了して、炊飯が遅れているときは、洗米器3での洗米部浸漬を終えた状態で、洗米器内の排水水切り行なった状態で、移動開始を待つが、このとき、洗米器3の洗米は浸漬作用を受けない状態で待機している。前記洗い方手段69の操作で、洗米を軽く行なう場合から念入りに行なうまで5段階に設定しておき、これを洗米時に予めいずれの洗い方モ−ドにするか設定しておく。この洗い方手段69で、5段階のいずれかの洗い方が選定されると、CPU21を経て、洗米モ−タ24、上給水用のソレノイドバルブ37、給水用のソレノイドバルブ36乃至排水弁32のソレノイドバルブ39等を出力して、洗米制御を行なう。
【0025】
洗い方の5段階の各モ−ドは制御出力として洗米時間、上給水時間、下給水時間、排水時間、これら洗米等の繰返し回数、洗米工程全体の時間等を、糠抜き、研米、荒すすぎ、オ−バ−フロ−による仕上すすぎ等の各工程毎に変更設定して、洗米を軽く行なうモ−ドから念入りに行なうモ−ドで5段階に設定してメモリ−されている。
【0026】
前記洗米器内を洗浄するには、図7のように排出弁32を有する排出口27の排出室(B)42を円筒形状の形態として構成し、この一側の排水室(A)31との間の連通路86,87を排水室(B)42に対して接線方向に設定し、前記左右一対の排水弁32および水位弁88を各連通路86,87の排水室(A)31側端に開閉するように対向させている。また、給水パイプ35の下部ノズル33は連通路86にのぞませている。
【0027】
水位弁88は排水弁32と同様にソレノイド89、ワイヤ−90等を経て開閉作動させるものであるが、下部ノズル33から下給水を行なうときは、連通路86を閉じて排水室(B)側へ案内させる。また、洗米後の排水を行なうときは、排水弁32とともに開くように制御している。
【0028】
洗米終了後、米と水とを排出弁26の開きによって投下完了した後、直ちに、排水弁32と水位弁88を閉じたままで、上給水のソレノイドバルブ37を開けて、上部シャワ−38から給水することによって、洗米器内に付着している糠や塵等を洗い流すことができ、その後、直ちに排水弁を開いて下部ノズル33から給水を行なうことにより、この下部給水は、連通路86から排水室(B)内へ勢いよく渦状に流れ込み、この洗浄水は反対側の連通路87から排水室(A)31へ排水されるため、効果的な洗浄を行なうことができる。91は排水室(A)31の排水口である。92はオ−バ−フロ−パイプで、オ−バ−フロ−口46からの越流水を一旦排水室(A)31を通して排水口91へ流下させる。
【0029】
洗米炊飯機1の各部をチェックするテスト運転を行なうときは、始動手段75とヘルプ手段78との両者の動じ入り操作の入力により、流量センサ34で水の流量が検出されずに、この流量が入力されないときであっても、計量器15の計量作動から開始されて、洗米炊飯機1の各部を回転駆動する構成としている。
【0030】
運転制御装置20は操作装置内に設け、各種手段の操作及び各種センサの検出が入力されるCPU21、CPU21からパネル回路を経て表示部の49へ各種ソレノイドバルブ36,37、ソレノイド39及びブザ−80等を始動する構成としている。
【0031】
運転制御装置20によるテスト運転制御について説明すると、スタ−トされ(ステップ101)、各種設定デ−タが確認され(ステップ102)、始動手段75が入り(ON)か検出され(ステップ103)、NOと検出されるとステップ103へ戻り、YESと検出されると各種センサの状態が確認され(ステップ104)、始動手段75とヘルプ手段78との両者が同時に入り操作されて入力されたか検出され(ステップ105)、YESと検出されると計量工程へと移行され(ステップ106)、NOと検出されると流量センサ34で流量が確認され(ステップ107)、ステップ106へ進む構成であり、洗米工程の糠抜き、研米、荒すすぎ及び仕上すすぎへ移行され(ステップ108)、投下可能か検出され(ステップ109)、NOと検出されるとざる上げ工程へ移行され(ステップ110)、ステップ109へ戻る構成であり、YESと検出されると投下工程へ移行され(ステップ111)、浸漬工程へ移行され(ステップ112)、炊飯工程へ移行され(ステップ113)、むらし工程へ移行され(ステップ114)、釜数=0か検出され(ステップ115)、YESと検出されると全工程終了か検出され(ステップ116)、YESと検出されるとリタ−ンする構成としている(ステップ117)。また、ステップ115及びステップ116でNOと検出されるとステップ102へ戻る構成としている。
【0032】
運転制御装置20による洗浄終了後の洗米を所定時間以上洗米器内へ保持したときの洗米器3への給水及び排水の制御は、図10に示している。すなわち、スタ−トされ(ステップ201)、各種設定デ−タが確認され(ステップ202)、始動手段75が入り(ON)か検出され(ステップ203)、NOと検出されるとステップ203へ戻り、YESと検出されると各種センサの状態が確認され(ステップ204)、流量センサ34で流量が確認され(ステップ205)、計量工程へと移行され(ステップ206)、洗米工程の糠抜き、研米、荒すすぎ及び仕上すすぎへ移行され(ステップ207)、投下可能か検出され(ステップ208)、NOと検出されるとざる上げ工程へ移行され(ステップ209)、ステップ208へ戻る構成であり、YESと検出されると洗米工程後経過時間(T)が>設定時間(T0)が検出され(ステップ210)、NOと検出されると投下工程へ移行され(ステップ211)、YESと検出されると投下準備工程へ移行され(ステップ212)、ステップ211へ進む構成であり、浸漬工程へ移行され(ステップ213)、炊飯工程へ移行され(ステップ214)、むらし工程へ移行され(ステップ215)、釜数=0か検出され(ステップ2165)、YESと検出されると全工程終了か検出され(ステップ217)、YESと検出されるとリタ−ンする構成としている(ステップ218)。また、ステップ216及びステップ217でNOと検出されるとステップ202へ戻る構成としている。
【0033】
上記により洗浄終了後に投下する釜が準備されていないと、水を抜いた状態で洗米器内で保持するが、この状態で一定時間保持すると、洗浄済の米は洗米器3の内壁に貼り付いたり、またかたまったりして投下しにくくなるが、一定時間以上保持すると、投下準備工程に入り下給水によって一旦ほぐし、流動性をよくした後に投下する構成としたものである。
【0034】
以下、実施例の作用について説明する。洗米炊飯機1の各部をチェックするテスト運転を行なうときは、操作装置19の始動手段75とヘルプ手段78との両者を入り操作することにより、この操作が運転制御装置20のCPU21へ入力され、この入力によって、流量センサ34で水の流量が検出されて、CPU21へ入力されない状態であっても、洗米炊飯機1の各部は、運転制御装置20によって始動制御され、水なしの状態で洗米炊飯機1の各部をチェックする。
