Description

【０００１】
【発明の属する技術分野】
本発明は、洗濯物を収容する内槽内に温風を送風可能とした洗濯機に関するものである。
【０００２】
【従来の技術】
従来、この種の乾燥機能を有した洗濯機は図４に示すような構成が提案されている。以下、その構成について説明する。
【０００３】
図４に示すように、外槽１は、洗濯物を収容する内槽２を内包し、外枠３内に複数のサスペンション４によって弾性的に吊り下げて設け、脱水時の振動を吸収する構成としている。内槽２は脱水軸５を中心に回転自在に配設し、内槽２の内底部に洗濯物を撹拌する回転翼６を洗濯軸７を中心に回転自在に配設している。内槽２の内部周壁に小孔（図示せず）を多数設けている。
【０００４】
外槽１の上方開口側に略ドーナツ状の外槽カバー８を配設し、この外槽カバー８の内方開口部を開閉自在に覆うように内蓋９を配設している。外槽１の底部にモータ１０を配設し、その回転力を洗濯時は洗濯軸７に伝達し、脱水時は脱水軸５に切り換えて伝達するクラッチ１１を介して、内槽２または回転翼６に連結している。
【０００５】
外枠１の上部に開口部を有する外枠カバー１２を配設し、その開口部を開閉自在に覆う外蓋１３を設けるとともに、内槽２に給水する給水弁１４を設け、給水蛇腹ホース１５を通して外槽１内に給水するよう構成している。外槽１の底部に外槽１外に水を排水する排水弁１６を設けている。
【０００６】
上記構成において動作を説明する。洗い行程では、外蓋１３と内蓋９を開けて、内槽２に衣類を投入し運転を開始すると、給水弁１４が開き、給水蛇腹ホース１５を通して所定の水位まで給水した後、モータ１０を駆動する。伝達機構部のクラッチ１１によりモータ１０の動力が洗濯軸７を介して回転翼６に伝達されて回転し、衣類どうしまたは内槽２や回転翼６との接触により作用する機械力と水流により衣類の洗浄が行われる。
【０００７】
脱水行程では、洗濯終了後、排水弁１６を開いて内槽２内の水を排水した後、クラッチ１１を脱水側に切り換えて、モータ１０の動力を脱水軸５に伝達して内槽２を回転し、遠心力により衣類から水分を分離させる。
【０００８】
【発明が解決しようとする課題】
しかしながら、このような従来の構成では、内槽２や外槽１を乾燥することができず、洗濯時の水が内槽２や外槽１に残水してかびや菌等を発生させてしまうという問題を有していた。
【０００９】
本発明は上記課題を解決するもので、洗濯後の残水をなくし、内槽だけでなく外槽まで乾燥させて、かびや菌の増殖を抑制することを目的としている。
【００１０】
【課題を解決するための手段】
本発明は上記目的を達成するために、外枠の上部に外枠カバーを配設し、洗濯物を収容し内部周壁に多数の脱水孔を設けた内槽を外枠内に弾性的に吊り下げられた外槽に回転可能に内包し、外槽の底部に設けられたモータにより内槽を回転駆動し、給水弁により内槽内に給水し、排水弁により外槽内の水を排水し、内方開口部を有する外槽カバーが外槽の上方開口側に配せられ、内蓋が内方開口部を開閉自在に覆い、外枠カバーの後方内部に設けられた温風送風手段により外気を吸気して加熱し内槽内に温風を送風し、外槽カバーの内方開口部の後方側で内槽内を臨む位置に設けられた温風供給口が温風送風手段に送風蛇腹ホースを介して接続し、外槽カバーに設けられた排気口から内槽内の温風を排出し、制御装置によりモータ、給水弁、排水弁および温風送風手段等を制御して洗い、すすぎ、脱水および乾燥の各行程を制御するよう構成し、制御装置は、温風送風手段を制御することによって内槽内に温風を供給するとともに、モータを制御して内槽を回転させることで内槽の脱水孔を通して内槽と外槽の間に温風を送り込む槽乾燥コースを実行できるようにし、内槽の外面には、外側に突出し内槽と外槽の間の温風を下方に送る複数の送風板を設け、送風板は、槽乾燥コースにおける内槽の回転方向側が、反回転方向側より上方になるように構成し、槽乾燥コースにおいては、内槽と外槽の間に送り込まれた温風が送風板の回転により内槽の下方周辺に回り込むことで、内槽の下面部および外槽の底面部を乾燥させるようにしたものである。
【００１１】
これにより、洗濯後の残水をなくし、内槽だけでなく外槽まで乾燥することができ、かびや菌の増殖を抑制することができる。
【００１２】
【発明の実施の形態】
本発明の請求項１に記載の発明は、外枠と、前記外枠の上部に配設した外枠カバーと、洗濯物を収容し内部周壁に多数の脱水孔を設けた内槽と、前記外枠内に弾性的に吊り下げられ前記内槽を回転可能に内包した外槽と、前記外槽の底部に設けられ前記内槽を回転駆動するモータと、前記内槽内に給水する給水弁と、前記外槽内の水を排水する排水弁と、前記外槽の上方開口側に配し内方開口部を有する外槽カバーと、前記内方開口部を開閉自在に覆う内蓋と、前記外枠カバーの後方内部に設けられ外気を吸気して加熱し前記内槽内に温風を送風する温風送風手段と、前記外槽カバーの前記内方開口部の後方側で前記内槽内を臨む位置に設けられ前記温風送風手段に送風蛇腹ホースを介して接続する温風供給口と、前記外槽カバーに設けられ前記内槽内の温風を排出する排気口と、前記モータ、給水弁、排水弁および温風送風手段等を制御して洗い、すすぎ、脱水および乾燥の各行程を制御する制御装置とを備え、前記制御装置は、前記温風送風手段を制御することによって前記内槽内に温風を供給するとともに、前記モータを制御して前記内槽を回転させることで前記内槽の前記脱水孔を通して前記内槽と前記外槽の間に温風を送り込む槽乾燥コースを実行できるようにし、前記内槽の外面には、外側に突出し前記内槽と前記外槽の間の温風を下方に送る複数の送風板を設け、前記送風板は、前記槽乾燥コースにおける前記内槽の回転方向側が、反回転方向側より上方になるように構成し、前記槽乾燥コースにおいては、前記内槽と前記外槽の間に送り込まれた前記温風が前記送風板の回転により前記内槽の下方周辺に回り込むことで、前記内槽の下面部および前記外槽の底面部を乾燥させるようにしたものであり、洗濯後の残水をなくし、内槽に設けた脱水孔より内槽と外槽の間に温風を送り込み、送風板により内槽と外槽の間の下方部に温風を送り込むことで、内槽だけでなく外槽まで効率よく乾燥することができ、かびや菌の増殖を抑制することができる。
【００１３】
【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。なお、従来例と同じ構成のものは同一符号を付して説明を省略する。
【００１４】
（実施例１）
図１に示すように、内槽１７は、内部周壁に多数の脱水孔１８を設け、外槽１に回転自在に内包している。外槽カバー１９は、は略ドーナツ状に形成して外槽１の上方開口側に配設し、この外槽カバー１９の内方開口部を開閉自在に覆うように内蓋２０を配設している。外枠カバー２１は外枠３の上部に配設し、この外枠カバー２１の後方内部に乾燥用送風機２２を配設し、その一端は吸気フィルター２３を介して機体外に通じており、他端はヒータ２４を有する温風供給路２５に接続し、温風送風手段２６を構成している。温風供給路２５は送風蛇腹ホース２７につながり、外槽カバー１９に設けた温風供給口２８から内槽２内へ温風を供給するよう構成している。
【００１５】
外槽カバー１９には、温風供給口２８から内槽２内に供給された温風を排気する排気口２９を形成し、その近傍に支持部材３０を固定し、排気フィルター３１を排気口２９を覆うように支持部材３０に着脱自在に取り付けている。
【００１６】
脱水孔１８は、温風送風手段２６により内槽１７内に供給された温風を内槽１７と外槽１の間に導く連通部を構成し、さらに、内槽１７の下方部に開口部３２を設け、この開口部３２により内槽１７内の温風を内槽１７と外槽１の間に導く連通部を構成している。また、内槽１７の底面に拡散板３３を設けている。
【００１７】
制御装置３４は、モータ１０、給水弁１４、排水弁１６などの動作を制御し、洗い、すすぎ、脱水などの一連の行程を逐次制御するとともに、温風送風手段２６により内槽１７内に温風を供給して衣類を乾燥させる乾燥行程を制御するよう構成し、さらに、内槽１７内に温風送風手段２６によって温風を供給するとともに、内槽１７を回転させることで内槽１７と外槽１の間に温風を送り込む槽乾燥コースを実行できるよう構成している。
【００１８】
上記構成において動作を説明する。洗い行程では、内槽１７に衣類を投入し運転を開始すると、給水弁１４が開き、給水蛇腹ホース１５を通して所定の水位まで給水した後、モータ１０を駆動する。伝達機構部のクラッチ１１によりモータ１０の動力が回転翼６に伝達されて回転し、衣類どうしまたは内槽１７や回転翼６との接触により作用する機械力と水流により衣類の洗浄が行われる。
【００１９】
脱水行程では、洗濯終了後、排水弁１６を開いて内槽２内の水を排水した後、クラッチ１１を脱水側に切り換えて、内槽１７を回転し、遠心力により衣類から水分を分離させる。
【００２０】
乾燥行程では、脱水終了後、排水弁１６を閉じるとともにクラッチ１１を洗濯側に切り換え、モータ１０を駆動して回転翼６に伝達し、回転翼６を正転、反転させて衣類を引っかけて撹拌する。また、乾燥用送風機２２とヒータ２４に通電し、吸気フィルター２３を通して吸入した外気を温風に変え、温風供給口２８から内槽１７内に温風を吹き込む。この温風が撹拌中の衣類を暖め、衣類から水分を蒸発させた後、内槽１７の上方に向かって上昇し、排気口２９から排出され、衣類を乾燥する。
【００２１】
つぎに、槽乾燥の専用コースを動作させると、排水弁１６を開けるとともにモータ１０を駆動して回転翼６および内槽１７に伝達し、回転翼６および内槽１７を回転させる。また、乾燥用送風機２２とヒータ２４に通電し、吸気フィルター２３を通して吸入した外気を温風に変え、温風供給口２８から内槽１７内に温風を矢印で示すように吹き込む。
【００２２】
内槽１７内に吹き込まれた温風は内槽１７の側面に配設した脱水孔１８および開口部３２を通って、矢印で示すように、内槽１７と外槽１の間に送り込まれる。内槽１７と外槽１の間に送り込まれた温風は、内槽１７と外槽１の間に充満し、次第に内槽１７と外槽１の間の底面へと充満していく。
【００２３】
したがって、内槽１７と外槽１の間全体に温風が充満・拡散し、内槽１７および外槽１を乾燥することができる。
【００２４】
ここで、開口部３２は内槽１７の下方部に設けているので、内槽１７内に供給された温風は、下方より内槽１７と外槽１の間に送り込まれ、送り込まれた温風は、内槽１７と外槽１の間を上昇していくので、内槽１７と外槽１の間全体に温風が充満し、内槽１７および外槽１を効率よく乾燥することができる。
【００２５】
また、内槽１７の底面に拡散板３３を設けているので、内槽１７内に供給された温風が内槽１７と外槽１の間に送り込まれ、内槽１７と外槽１の間に充満し、次第に内槽１７の下面周辺に回り込む際、内槽１７の下面周辺に回り込んだ温風は、拡散板３３により流れが起こり、内槽１７の下面部および外槽１の底面部を効率よく乾燥することができる。
【００２６】
なお、本実施例では、内槽１７の内部周壁に多数の脱水孔１８を設けるとともに、内槽１７の下方部に開口部３２を設けているが、脱水孔１８と開口部３２のいずれかを設けるだけでもよい。
【００２７】
また、本実施例では、洗い、すすぎ、脱水などの一連の行程を逐次制御するとともに、乾燥行程を制御するよう構成しているが、乾燥行程はなくてもよい。
【００２８】
（実施例２）
図２に示すように、内槽１７ａは、内部周壁に多数の脱水孔１８を設け、外槽１に回転自在に内包している。内槽１７ａの外面に、内槽１７ａと外槽１の間に送り込まれ温風を下方に送る送風板３５を設けている。他の構成は上記実施例１と同じであり、同一符号を付して説明を省略する。
【００２９】
上記構成において動作を説明する。なお、洗い行程から乾燥行程の動作は上記実施例１と同じであるので説明を省略する。
【００３０】
つぎに、槽乾燥の専用コースを動作させると、内槽１７ａ内に供給された温風は、内槽１７ａと外槽１の間に送り込まれ、内槽１７ａと外槽１の間に充満し、内槽１７ｂが回転しているため、送風板３５により、矢印で示すように、内槽１７ａと外槽１の間の下方に送り込まれ、内槽１７ａの下方周辺に回り込み、内槽１７ａの下面部および外槽１の底面部を乾燥することができる。これにより、内槽１７ａと外槽１を効率よく乾燥することができる。
【００３１】
（実施例３）
図３に示すように、外槽１ｂは、内槽１７ｂを回転自在に内包している。この外槽１ｂの内面に、内槽１７ｂと外槽１ｂの間に送り込まれ温風を下方に送る導入板３６を設けている。他の構成は上記実施例１と同じであり、同一符号を付して説明を省略する。
【００３２】
上記構成において動作を説明する。なお、洗い行程から乾燥行程の動作は上記実施例１と同じであるので説明を省略する。
【００３３】
つぎに、槽乾燥の専用コースを動作させると、内槽１７ｂ内に供給された温風は、内槽１７ｂと外槽１ｂの間に送り込まれ、内槽１７ｂと外槽１ｂの間に充満し、内槽１７ｂが回転しているため、導入板３６により、矢印で示すように、内槽１７ｂと外槽１ｂの間の下方に送り込まれ、内槽１７ｂの下方周辺に回り込み、内槽１７ｂの下面部および外槽１ｂの底面部を乾燥することができる。これにより、内槽１７ｂと外槽１ｂを効率よく乾燥することができる。
【００３４】
