以下、第3実施形態について説明する。第3実施形態に係る洗濯機10は、第1実施形態、又は第2実施形態に係る洗濯機10の構成に、更に、柔軟剤用給水弁37、柔軟剤管43、柔軟剤ケース62を加えた構成を備えている。以下詳述する。
最終すすぎ行程の初めすなわち給水に柔軟剤を溶解させる期間内に、ファインバブル水を柔軟剤が予め投入された柔軟剤ケース62に供給する制御を実施する構成としたので、柔軟剤を効率よく分散させた状態でファインバブル水に溶解することを可能とした。これにより柔軟剤が衣類へ浸透やすくなり、洗濯後の衣類がより柔らかな仕上がりとなるため、最終すすぎ時の柔軟効果を向上させた洗濯機10を提供することができる。
図6から図10を参照して、第4実施形態について説明する。なお、図6から図9は、以下に説明する第4実施形態から第9実施形態に係る洗濯機101に共通の構成を示している。図6は、本実施形態に係る洗濯機101の全体構成を概略的に示しており、この洗濯機101は、例えば鋼板から全体として矩形箱状に構成された外箱102の上部に、合成樹脂製のトップカバー103を備えている。前記外箱102内には、洗濯水を溜めることが可能な水槽104が、周知構成の弾性吊持機構(図示せず)により弾性的に吊り下げ支持されて設けられている。尚、詳しい図示はしないが、水槽104の底部には、排水口が形成され、この排水口に、排水弁132(図9にのみ図示)を備えた排水路が接続されている。また、外箱102内には、水槽104の底部に設けられたエアトラップに接続されたエアチューブを介して、水槽104内の水位を検出する水位センサ133(図9にのみ図示)も設けられている。
図11は、第5実施形態を示すものである。この第5実施形態が、上記第4実施形態と異なる点は、制御装置131による、洗い行程開始時の給水における、FB用給水弁121とメイン給水弁120との開閉制御の処理にある。即ち、この第5実施形態では、制御装置131は、メイン給水弁120とFB用給水弁との切替え制御を、時間制御に代えて、水位センサ133の検出による洗濯槽105内の水位検出に基づいて行うようになっている。
図12は、第6実施形態を示すものである。この第6実施形態が、上記第4、第5実施形態と異なる点は、制御装置131による、洗い行程開始時の給水における、FB用給水弁121とメイン給水弁120との開閉制御の処理にある。即ち、この第6実施形態では、制御装置131は、メイン給水弁120とFB用給水弁との切替え制御を、時間制御や水位制御に代えて、流量計135の検出値の時間積算による洗濯槽105内への給水量の算出に基づいて行う。この場合、メイン給水における水の流量は、例えば10リットル/分であり、FB給水における水の流量は、例えば5リットル/分とされている。図12の下段は、ハッチングを付した面積が、その区間において給水された水量を表している。
図13は、第7実施形態を示すものであり、上記第4実施形態と異なる点は、制御装置131による、洗い行程開始時の給水における、FB用給水弁121とメイン給水弁120との開閉制御の処理にある。即ち、この第7実施形態では、制御装置131は、メイン給水弁120とFB用給水弁との切替え制御を、時間カウント及び水位センサ133による洗濯槽105内の水位検出に基づいて行う。この場合、上記第5実施形態と同様に、基本的には水位検出に基づく制御を行いながらも、それに時間制御が加味される。
図14は、第8実施形態を示すものであり、上記第4実施形態と異なる点は、制御装置131による、洗い行程開始時の給水における、FB用給水弁121とメイン給水弁120との開閉制御の処理にある。即ち、この実施形態では、制御装置131は、給水の開始時に、メイン給水弁120の開放を先行して行うように構成されている。
図15は、第9実施形態を示すもので、上記第4実施形態と異なるところは、制御装置131は、給水の開始時に、FB用給水弁121の開放を先行して行い、その後に、メイン給水弁120とFB用給水弁121との双方を同時に開放する点にある。即ち、洗い行程が開始されると(時刻t0)、まず、FB用給水弁121が開放され、FB給水が例えば60秒間実行される。そして、時刻t1になった時点で、FB用給水弁121は開放のままで、メイン給水弁120が開放される。
