Description

【0001】
【発明の属する技術分野】
本発明はガス調理機器の制御装置に関する。
【0002】
【従来の技術】
従来、電池で制御回路を駆動するガス調理機器は、点火動作や、点火動作に関わる制御しか行っていなかったので、電池容量の残量や、電池交換を認識する必要がなかった。
【0003】
【発明が解決しようとする課題】
しかしながら近年、ガス調理機器は、より利便性が要求されるようになり、例えば温度センサーなどで調理物の温度を検知し、その制御状態を記憶しておいて、次回の使用に反映するなどの制御が必要となってきている。ところが、従来のガス調理機器の制御装置は、一般に電池電力で駆動しているため、電池交換時に制御装置への電力供給が途切れてしまい、制御状態の記憶が消えてしまう。
【0004】
そこで、電池交換などの時間程度では電力供給が途切れないようにバックアップ電源を設ける等の工夫をすることが考えられるが、制御装置が、電池が新しいものに交換されたことを確認をしたい場合、電池の出力電圧は、機器の使用状態、例えばコンロを使用している場合、あるいはグリルを使用している場合等によって変動するので、比較基準電圧が1つだけの電圧比較では電池が新しいものに交換されたことを判断できない場合がある。
【0005】
本発明は、このような制御装置において、電池が新しいものに交換されたことを判別できるようにすることを目的とする。
【0006】
【課題を解決するための手段】
本発明は、調理開始手段によって調理を開始させると、調理制御回路負荷を制御する制御手段が、前記調理開始手段に対応した調理制御回路負荷に応じて予め決めておいた電池交換判別用の基準電圧と電池の電圧とを比較して、その比較結果より電池が所定電圧以上の新しい電池に交換されたか否かを判別し、新しい電池に交換されたと判別した場合、前記調理制御回路負荷に応じた制御シーケンスへ移行する構成としてある。
【0007】
上記本発明によれば、調理開始手段に対応した調理制御回路負荷の状態によって電池電
圧と比較する電池交換判別用の基準電圧を換えるようにしているので、調理制御回路負荷によって電池電圧が変動しても、所定電圧以上の新しい電池に交換されたか否かを判別することができ、新しい電池に交換されたことが判別されると、調理制御回路負荷に応じた制御シーケンスに移行することができる。
【0008】
【発明の実施の形態】
本発明の請求項1に記載の発明は、装置を駆動する電源としての電池と、調理を開始させる調理開始手段と、前記調理開始手段によって動作し調理制御回路負荷を制御する制御手段とを備え、前記制御手段は前記調理開始手段に対応した調理制御回路負荷に応じて予め決めておいた電池交換判別用の基準電圧と前記電池の電圧とを比較して、その比較結果より電池が所定電圧以上の新しい電池に交換されたか否かを判別し、前記電池が所定電圧以上の新しい電池に交換されたと判別した場合、前記調理制御回路負荷に応じた制御シーケンスへ移行する構成としてある。従って、制御装置は調理制御回路負荷に応じて電池の電圧を確認して新しい電池に交換されたか否かを判別することができ、新しい電池に交換されたことが判別されると、調理制御回路負荷に応じた制御シーケンスに移行することができる。
【0009】
また請求項2記載の発明は、複数の調理開始手段を有すると共に、制御手段は各調理開始手段に対応した調理制御回路負荷に応じて予め決めておいた電池交換判別用の基準電圧を備え、前記調理開始手段の操作に応じて前記電池交換判別用の基準電圧と電池の電圧とを比較するようにしてあるので、複数の調理制御回路負荷があってもその調理制御回路負荷に応じた電池交換判別用の基準電圧と電池の電圧とを比較するので確実に新しい電池に交換されたか否かを判別することができる。
【0010】
以下、本発明の実施例について、図1、図2を用いて説明する。
(実施例1)
図1において、1はガス調理機器の電源となる電池、2はこの電池1の電圧を比較する比較器で、電池用の入力端子2aと制御装置5からの入力端子2bとを有している。3、4は調理開始手段で、3はこんろ調理開始用、4はグリル調理開始用である。5は前記した制御装置で、マイクロコンピュータを主体に構成してあり、前記こんろ、グリル各調理開始手段3、4からの調理開始信号に基づいてそれぞれに対応した調理制御回路負荷7、9をトランジスタ6、8を介して駆動するとともに、この各調理制御回路負荷7、9に応じてあらかじめ決めておいた電池交換判別用の基準電圧を前記入力端子2bに送るようになっている。なお図中10は電池交換時に制御装置5に記憶されている制御状態等の記憶内容が消えないようにするためのバックアップ電源である。
【0011】
上記構成において、次にその動作を図2のフローチャートを参考に説明する。まずステップ101で調理開始手段の一つであるこんろ調理開始手段3がオンになると、マイクロコンピュータを主体に構成されている制御装置5は、トランジスタ6をオンし、こんろ用に予め決めておいた基準電圧、即ちこんろ調理開始手段3がオンのときの基準電圧を、比較器2の入力端2bに入力する。比較器2は、ステップ102で電池1から端子2aに入力された電圧と、制御装置5より端子2bに入力された電圧を比較し、その比較結果を制御装置5に伝え、制御装置5は、その比較結果より電池が所定電圧以上の新しいものに交換されたか否かを判断する。
【0012】
同様にステップ103でグリル調理開始手段4がオンになると、制御装置5は、トランジスタ8をオンし、予め決めておいた、グリル調理開始手段4がオンのときの基準電圧を、比較器2の入力端2bに入力する。比較器2は、ステップ104で電池1から端子2aに入力された電圧と、制御装置5より端子2bに入力された電圧を比較し、その比較結果を制御装置5に伝え、制御装置5は、その比較結果より電池が所定電圧以上の新しいものに交換されたか否かを判断する。
【0013】
そして、上記いずれの場合もステップ105、106で電池が交換されたか交換されていないかを認識したのち、それぞれの調理制御回路負荷7、9に応じた制御シーケンスへと移行する。
【0014】
なお、制御装置5から入力端2bに入力する基準電圧は、こんろ調理制御回路負荷7と、グリル調理制御回路負荷9の状態によって予め決めておけば負荷に応じた基準電圧を設定することができる。
【0015】
また、上記電池電圧のチェックは調理開始手段の操作によって自動的に行われるようにするだけでなく、電池電圧チェックスイッチ等を設けてこのスイッチが操作されたときにチェックするようにしてもよい。
【0016】
更に電池交換表示ランプ等の表示手段を設けて所定電圧以上の電池、すなわち新しい電池に交換された場合にこれを点灯させる等して表示するようにしても良い。
【0017】
【発明の効果】
以上のように本発明の請求項1に記載の発明は、装置を駆動する電源としての電池と、調理を開始させる調理開始手段と、前記調理開始手段によって動作し調理制御回路負荷を制御する制御手段とを備え、前記制御手段は前記調理開始手段に対応した調理制御回路負荷に応じて予め決めておいた電池交換判別用の基準電圧と前記電池の電圧とを比較して、その比較結果より電池が所定電圧以上の新しい電池に交換されたか否かを判別し、前記電池が所定電圧以上の新しい電池に交換されたと判別した場合、前記調理制御回路負荷に応じた制御シーケンスへ移行する構成としてあり、制御装置は調理制御回路負荷に応じて電池の電圧を確認して新しい電池に交換されたか否かを判別することができ、新しい電池に交換されたことが判別されると、調理制御回路負荷に応じた制御シーケンスに移行することができる。
【0018】
また請求項2記載の発明は、複数の調理開始手段を有すると共に、制御手段は各調理開始手段に対応した調理制御回路負荷に応じて予め決めておいた電池交換判別用の基準電圧を備え、前記調理開始手段の操作に応じて前記電池交換判別用の基準電圧と電池の電圧とを比較するようにしてあり、複数の調理制御回路負荷があってもその調理制御回路負荷に応じた電池交換判別用の基準電圧と電池の電圧とを比較するので、調理制御回路負荷によって電池電圧が変動しても確実に新しい電池に交換されたか否かを判別することができる。
