Description

【0001】
【発明の属する技術分野】
本発明は、食器の洗浄、漂白を行う食器洗浄機に関する。
【0002】
【従来の技術】
従来のこの種の食器洗浄機は、漂白成分を含有させた洗浄水を食器に噴射することで食器の漂白を行っており、本洗い後のすすぎ行程、又は予洗行程、あるいは単独の漂白行程で漂白することにより、漂白、脱臭、殺菌効果を発揮するものがあった。漂白成分としては、家庭に常時ある食塩を用いて洗浄水と混合して電気分解することにより、高濃度の遊離塩素を洗浄水中に生成して食器の漂白を行うようにしていた(例えば、特許文献1参照。)。
【0003】
【特許文献1】
特許第3245958号公報
【0004】
【発明が解決しようとする課題】
遊離塩素などの漂白成分は、その酸化分解力で漂白作用を行うものであり、酸化分解されやすい分子構造を有するゴム材料や樹脂材料においては、材料の劣化が懸念される。また金属材料においても酸化されて錆の発生が懸念される。食器洗浄機の洗浄槽やその他の接水部品には、基本的な性能や生産性やコストなどの面からこれらの材料を使用する場合が多いが、使用条件や漂白性能等から予め想定された漂白濃度と漂白温度と漂白時間の範囲内で、材料設計および選定を行うことは可能である。しかしながら、実際の食器洗浄機の使用においては、洗浄水が洗浄槽中に滞留したままで長時間放置される場合があり、その場合には、洗浄槽やその他の接水部品が必要以上に長時間漂白成分にさらされることになるため、これらの部材の劣化が問題となる場合があった。
本発明は、上記課題を解決するためになされたもので、本発明の目的は、洗浄槽やその他の接水部品が、漂白成分を含有した洗浄水に必要以上に長時間さらされることがなく、接水部品の劣化の小さい、食器洗浄機を提供することにある。
【0005】
【課題を解決するための手段】
上記目的を達成するために本発明においては、食器等の被洗浄物を収納する洗浄槽と、該洗浄槽の開口に備えた扉と、該洗浄槽に洗浄水を供給する給水手段と、該給水手段で給水された洗浄水中に漂白成分を含有させる漂白手段と、該漂白成分を含有する洗浄水を噴射させて被洗浄物を漂白洗浄する洗浄手段と、該漂白成分を含有する洗浄水を洗浄槽から排出する排水手段とを備え、食器の漂白洗浄を行う漂白工程を含む複数の工程を実行する食器洗浄機において、前記漂白工程において食器洗浄機の運転が一時停止されたときに、一時停止の開始から所定時間後に報知手段を動作させ、報知手段の動作開始から所定時間後に、報知手段の動作を停止して、一時停止前の運転を再開継続するようにしたので、食器洗浄機が一時停止状態であることを使用者が認知しやすくなり、使用者が一時停止状態を解除することができる。また、使用者の不在時や、使用者が報知に気づかない場合でも、運転を継続して終了させることができ、洗浄槽やその他の接水部品が、漂白成分を含有した洗浄水に必要以上に長時間さらされることがなくなる。
【0006】
また、前記報知手段の動作開始から所定時間後に、前記扉の開状態を検出した場合には、排水手段を動作させるようにしたので、開いた扉から漂白成分を含有した洗浄水が飛び出すことの無いように、洗浄槽やその他の接水部品が漂白成分を含有した洗浄水に必要以上に長時間さらされることをなくせる。前記排水手段の動作後に、前記洗浄槽に所定量の給水を行ってから、前記排水手段を再動作させるようにしたので、排水後に洗浄槽に残留する洗浄水中の漂白成分の濃度を小さくでき、さらに接水部品の劣化への影響度を小さくできる。
したがって、本発明によれば、洗浄槽やその他の接水部品が、必要以上に長時間漂白成分にさらされることがなく、接水部品の劣化の小さい、食器洗浄機を提供することができる。
【0007】
【発明の実施の形態】
以下に、本発明の実施の形態について、図面を参照しながら説明する。
【0008】
図1は本発明の一実施形態の食器洗浄機の内部構造図である。食器洗浄機1は内部に洗浄水を溜める洗浄槽2を備え、洗浄槽2に食器を出し入れするための扉50と、洗浄槽2の内部に食器を収納する食器かご3と、食器に向けて洗浄水を噴射するノズル4を備える。扉50の開閉を検出する扉検出手段51を備え、扉50が開いていることを検出して、開いた扉50から洗浄水が飛散しないように食器洗浄機1の運転を停止させることができる。洗浄槽2の下方にはポンプ5を備え、ポンプ5はノズル4から食器に向けて洗浄水を噴射するべく、洗浄水を圧送する。洗浄槽2内へ洗浄水の供給を行う給水手段としては給水経路6と給水経路6の開閉を行う電磁弁7を備え、洗浄槽2内に溜めた洗浄水の水位を検出する水位検出手段8を備えて、所定の水位まで洗浄水を溜めるように電磁弁7の開閉を行うことができる。
【0009】
また、洗浄槽2には洗浄水を加熱する温水ヒーター9および洗浄水の温度を検出する温水温度検出手段10を備え、温水温度検出手段10の出力に基づいて温水ヒーター9を運転して、洗浄水の温度を所定の温度に維持することができる。
ポンプ5は、洗浄水を食器に向けて噴射する洗浄手段としての機能と、洗浄水を食器洗浄機1の外部へと排出する排水手段としての機能とを合わせもつようにしてもよく、その場合はポンプ5は排水経路11に連通する。ポンプ5、電磁弁7、温水ヒーター9を適宜運転することにより、所定温度で所定の水量の洗浄水によって食器の洗浄を行うことができる。食器洗浄機1の内部には制御装置15を備え、食器洗浄機1の前面には操作パネル39を備えている。また食器洗浄機1には、洗浄水の漂白手段19を備え、洗浄水に漂白成分を含有させる。漂白手段19は、食塩を含有した洗浄水を電気分解することで、洗浄水中に遊離塩素を生成する電気分解手段20であってもよい。
【0010】
食器洗浄機1による食器の洗浄は、洗い工程、すすぎ工程、最終すすぎ工程を逐次実行することによって行われ、各工程の実施回数ならびに各工程における実施時間および洗浄水の加熱到達温度があらかじめ制御装置15内部のプログラムとして設定された洗浄コースを使用者が選択して実行するもので、食器の汚れや量に応じて洗浄コースを選択できるように、設定の異なる複数の洗浄コースを備える。
【0011】
洗い工程、すすぎ工程、最終すすぎ工程のそれぞれの工程内においては、給水工程、循環工程、排水工程が逐次実行される。すなわち給水工程では、電磁弁7を開成し洗浄槽2内に洗浄水を供給し、水位検出手段8からの信号によって所定の水位まで到達したことを制御装置15が認識すると電磁弁7を閉止する。循環工程では洗浄槽2内の洗浄水をポンプ5がノズル4に圧送し、食器に向かって噴射し、洗浄槽2内の洗浄水を循環する。排水工程では洗浄槽2内の洗浄水をポンプ5によって食器洗浄機1の外部に排出する。
【0012】
洗い工程と最終すすぎ工程においては、洗浄槽2に貯水される洗浄水を、循環工程において温水ヒーター9によって加熱しながらポンプ5による噴射および循環を行う。すすぎ工程においては温水ヒーター9による洗浄水の加熱は行なわずに、ポンプ5による洗浄水の噴射および循環を行なう。すすぎ工程において食器の漂白が実行される場合には、循環工程において電気分解手段20が運転されて洗浄水を電気分解して漂白成分である遊離塩素を生成しながら、ポンプ5による洗浄水の噴射および循環を行なう。この場合も温水ヒーター9による洗浄水の加熱は行なわない。
【0013】
図2は本発明の一実施形態の食器洗浄機の操作パネルの概略図である。操作パネル39には、電源の入/切を行う電源スイッチ25、運転の開始および一時停止を行うスタート/一時停止スイッチ26、洗浄コースを選択する洗浄コーススイッチ27、漂白の実施可否を選択する漂白スイッチ28、運転状況として実行中の工程を表示する工程表示LED31、選択された洗浄コースを表示する選択コース表示LED32、漂白の実行の有無を表示する漂白LED33を備える。
さらに、漂白における食塩の投入タイミングを表示する食塩投入LED34、一時停止状態を表示する一時停止LED35を備える。また操作パネル39もしくは制御装置15にブザー38を備えて、操作パネル39のLED31乃至35の点灯や点滅の組み合わせに合わせてブザー38を鳴らし、食器洗浄機1の運転状態や異常報知を行うことができる。
【0014】
図3は本発明の一の実施形態の食器洗浄機のフローチャートである。食器洗浄機1の漂白工程において、一時停止スイッチ26が押されると、一時停止LED35を点灯、漂白手段19とポンプ5を停止して、一時停止状態になる。一時停止後、所定時間が経過すると、ブザー38を動作させ、一時停止LED35を点滅して、一時停止報知を行う。一時停止報知の所定時間後、扉50が開いていることを検出している場合には、ブザー38を停止して、ポンプ5を動作させて、洗浄水の排水をおこなう。その後、給水工程として電磁弁7を開き、所定の水位まで給水して電磁弁7を閉じ、再度排水工程としてポンプ5を排水動作させて所定時間後にポンプ5を停止する。この間、一時停止LED35は点滅させたままとし、ポンプ5の停止後も一時停止LED35を点滅させる。一時停止LED35の点滅表示により漂白運転が中断されたままで運転を終了したことを、使用者が認知できるため、その後の使用において、使用者は一時停止のまま放置しないように意識するようになる。電源スイッチ25を押すと、一時停止LED35は消灯する。
【0015】
一方、一時停止報知において、所定時間内にスタートスイッチ26が押されるか、扉50が閉じていることを検出している場合には、ブザー38を止めて一時停止LED35を消灯して、運転を再開継続する。
【0016】
なお、一時停止報知は、一時停止されてからの経過時間だけでなく、洗浄水の漂白成分濃度に応じて報知をおこなってもよい。漂白運転開始後すぐに一時停止された場合など洗浄水中に漂白成分がなければ、一時停止報知を行わないようにもできるため、使用者が報知にわずらわされることを軽減できる。洗浄水の漂白成分濃度は、直接的に遊離塩素濃度センサーを用いたり、水素イオン濃度センサー(pHセンサー)で代用したりすることができる。また漂白手段の動作時間から漂白成分濃度を推定するようにしてもよいし、さらに、洗浄水の温度と組み合わせて報知をおこなうようにしてもよい。
【0017】
さらにまた、一時停止報知は、報知の回数または一時停止の積算時間に基づいて、排水手段を動作させるようにしてもよい。一時停止報知と運転の再開を何度も繰り返されることによって、一時停止報知を開始するまでの一時停止時間が積算されて、必要以上に長時間一時停止されることになることを防止することができる。また、一時停止報知の実施の有無を、所定のスイッチ操作にて変更設定できるようにしてもよく、使用者が報知によってわずらわされることがなくなる。
【0018】
また、一時停止されたときに乾燥コースが設定されていたときは、一時停止報知と排水動作の後に、設定されていた乾燥コースを実行するようにしてもよいし、漂白工程だけでなく、洗い工程やすすぎ工程でも一時停止報知を行うようにしてもよい。なお、本発明の内容を逸脱しない範囲でいかなる実施の形態も取ることができるのは言うまでもない。
【0019】
【発明の効果】
本発明は上記構成により、食器洗浄機が一時停止状態であることを使用者が認知しやすくなり、使用者が一時停止状態を解除することによって、洗浄槽やその他の接水部品が、漂白成分を含有した洗浄水に必要以上に長時間さらされることがなく、接水部品の劣化の小さい、食器洗浄機を提供することができる。使用者の不在時や、使用者が報知に気づかない場合でも、洗浄槽やその他の接水部品が、漂白成分を含有した洗浄水に必要以上に長時間さらされることがなく、洗浄槽に残留する洗浄水中の漂白成分の濃度を小さくでき、さらに接水部品の劣化への影響度を小さくできる。
