Description

【0001】
【発明の属する技術分野】
本発明は、回転ドラム内で洗濯、すすぎ、脱水、乾燥などの各行程を逐次行うドラム式洗濯乾燥機に関するものである。
【0002】
【従来の技術】
従来、この種のドラム式洗濯乾燥機は図11に示すような構成であった。以下、その構成について説明する。
【0003】
図11に示すように、筐体1は、内部に複数のサスペンション2とダンパー3で水槽4を支持しており、水槽4の開口部をドア5により開閉するようにしている。水槽4内に、略傾斜方向に回転軸を有する回転ドラム6を回転自在に配設し、この回転ドラム6に多数の通水孔7とバッフル8を設けている。
【0004】
筐体1に洗濯用給水弁(給水手段)9と乾燥用給水弁10とを設け、水槽4に設けた排水口11と排水ポンプ(排水手段)12とを排水経路13により連通している。送風機15は水槽4内に吹き出し口14を介して送風するもので、この送風機15にヒータ16を連通し、水槽4内と送風機15と連通した熱交換器17とによって、一連の乾燥循環経路を構成している。給水ホース18は乾燥用給水弁10から熱交換器17内に通水するものである。
【0005】
上記構成において洗濯、乾燥行程の動作を説明する。回転ドラム6内に洗濯物を投入して洗濯行程を開始すると、洗濯用給水弁9が開き水槽4内に所定の水位まで給水する。つぎに、回転ドラム6を約50r/minの回転数で駆動し、投入された衣類はバッフル8によって持ち上げられては落下を繰り返し、洗剤水と水面に落下したときの衝撃力によって洗浄される。
【0006】
洗濯行程が終わると排水ポンプ12を駆動し、洗濯水を排水経路13を通じて排水する。排水が終わると回転ドラム6を約1000r/minの回転数で高速回転し脱水を行う。さらに脱水行程が終了すると乾燥行程へ移行する。
【0007】
乾燥行程では洗濯行程と同様に、回転ドラム6を駆動し、回転ドラム6内の洗濯物を撹拌しながら送風機15とヒータ16によって加熱された熱風を回転ドラム6内の衣類に吹き出し口14から吹き付け、衣類内に含まれた水分を加熱し蒸発させる。
【0008】
さらに、蒸気を含む高温の空気は熱交換器17内に送られ、乾燥用給水弁10から熱交換器17内に供給された冷却水と混合し、熱交換を行い冷却除湿される。さらに、また除湿された空気はヒータ16によって再び加熱され、回転ドラム6内に送られ衣類の乾燥を行う。これによって一連の乾燥サイクルを形成する。
【0009】
【発明が解決しようとする課題】
このような従来の構成において、寸法面で制約を受ける筐体1内で一連の乾燥循環経路を構成しようとするとき、筐体1と水槽4の隙間を確保しなければならず、十分な断面積の熱交換器17を構成することができず、乾燥性能に対して不利になっていた。
【0010】
さらに、この種の熱交換器17は冷却水を循環風の風圧で、熱交換器17内でバランスよく飛散させ、熱交換を行う方式であるため、乾燥性能の向上を意図し、循環風量を安易に多くすると、断面形状の狭い熱交換器17内の風圧が上がりすぎ、飛散する冷却水とのバランスが崩れ、冷却水が巻き上げられてヒータ16まで達し、乾燥性能を著しく落とすという問題があった。
【0011】
さらに、毛足の長い衣類やペットの毛等が付着した衣類を乾燥すると、熱交換器17の内部に堆積して、故障の原因となっていた。
【0012】
本発明は上記従来の課題を解決するもので、熱交換器を構成することなく、水槽内の広い空間内で除湿を行うようにして除湿性能を向上するとともに、風圧による冷却水の巻き上げやリントなどの堆積による詰まりをなくすることを目的としている。
【0013】
【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、略水平方向または略傾斜方向に回転軸を有する回転ドラムを水槽に内包し、水槽内に給水手段により給水するとともに、水槽内の水を排水手段により排水し、水槽内に加熱手段と連通した送風手段により送風し、除湿手段により水槽内の洗濯物から蒸発した水分を冷却水によって除湿するよう構成し、除湿手段は、水槽と回転ドラムの間の空気を冷却水によって冷却して除湿するよう構成したものである。
【0014】
これにより、熱交換器を構成することなく、水槽内の広い空間内で除湿を行うことができ、除湿性能を向上することができるとともに、風圧による冷却水の巻き上げやリントなどの堆積による詰まりをなくすることができる。

【0025】
【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。
【0026】
(実施例1)
図1に示すように、回転ドラム6は、略傾斜方向に回転軸を有し、水槽4内に回転自在に配設している。給水ホース19は、乾燥用給水弁(給水手段)10と水槽4内とを連通し、この給水ホース19の先端にノズル20を取り付け、ノズル20を水槽4と回転ドラム6によって構成された空間に開口し、水槽4と回転ドラム6の間に冷却水を噴出し、水槽4内の洗濯物から蒸発した水分を冷却水によって除湿するよう構成している。
【0027】
上記構成において動作を説明する。乾燥行程では、洗濯行程と同様に、回転ドラム6を駆動し、回転ドラム6内の洗濯物を撹拌しながら、送風機(送風手段)15とヒータ(加熱手段)16によって加熱された熱風を回転ドラム6内の衣類に吹き出し口14から吹き付け、衣類内に含まれた水分を加熱し蒸発させる。蒸気を含む高温の空気は回転ドラム6に設けた多数の通水孔7を通って水槽4内に入る。
【0028】
水槽4内に入った蒸気を含む高温の空気は、乾燥用給水弁10から給水ホース19を介して、水槽4と回転ドラム6によって構成された空間にノズル20より噴射された冷却水と混合され、熱交換を行い冷却除湿される。この除湿された空気はヒータ16によって再度加熱され、回転ドラム6内に送られ衣類の乾燥を行う。これによって一連の乾燥サイクルを形成する。
【0029】
このように本実施例によれば、個別に水槽4の外部に熱交換器を備えることなく、水槽4と回転ドラム6の間の広い空間内で除湿を行うことができ、除湿性能を向上することができるとともに、風圧による冷却水の巻き上げやリントなどの堆積による詰まりをなくすることができる。
【0030】
なお、本実施例では、略傾斜方向に回転軸を有する回転ドラム6を水槽4内に回転自在に配設しているが、略水平方向に回転軸を有する回転ドラムを水槽4内に回転自在に配設してもよく、同様の作用効果を得ることができる。
【0031】
(実施例2)
図2に示すように、冷却ノズル21は水槽4の壁面に取り付け、水槽4内に開口した複数個の通水孔22を有し、冷却ノズル21と乾燥用給水弁10とを給水ホース23により連通し、冷却ノズル21の通水孔22より水槽4の内壁に沿って冷却水を流して除湿するよう構成している。他の構成は上記実施例1と同じである。
【0032】
上記構成において動作を説明する。乾燥行程で、乾燥用給水弁10から給水ホース23を介して、冷却ノズル21に通水され、複数個の通水孔22から出た冷却水は水槽4の内壁面を冷やしながら流れ落ちる。これによって水槽4内の蒸気を含む高温の空気は、冷やされた水槽4の内壁面と接触し熱交換を行いながら冷却除湿される。除湿された空気はヒータ16によって再び加熱され、回転ドラム6内に送られ衣類の乾を行なうといった、一連の乾燥サイクルを形成する。
【0033】
このように本実施例によれば、個別に水槽4の外部に熱交換器17を備えることなく、水槽4の内壁の広い面で除湿を行うことができ、風圧による冷却水の巻き上げやリントなどの堆積による詰まりをなくすることができる。
【0034】
(実施例3)
図3に示すように、冷却ノズル(冷却水通水路)24は、冷却水を流すもので、水槽4と一体に壁面に成型し、給水ホース23により乾燥用給水弁10と連通し、水槽4内に開口した複数個の通水孔22を設けている。他の構成は上記実施例1または2と同じである。
【0035】
上記構成において動作を説明する。乾燥行程で、乾燥用給水弁10から給水ホース23を介して、冷却ノズル24に通水され、複数個の通水孔22から出た冷却水は水槽4の内壁面を冷やしながら流れ落ちる。これによって水槽4内の蒸気を含む高温の空気は、冷やされた水槽4の内壁面と接触し熱交換を行いながら冷却除湿される。除湿された空気はヒータ16によって再び加熱され、回転ドラム6内に送られ衣類の乾を行なうといった、一連の乾燥サイクルを形成する。
【0036】
このように本実施例によれば、水槽4と冷却ノズル24を一体で成型することによって、簡単な構成で水槽4の内壁面に冷却水を効果的に分散させることができ、除湿性能を向上することができ、また、個別にノズルや取り付るための部品を必要とせず、コストを削減することができる。
【0037】
(実施例4)
図4に示すように、冷却ノズル(冷却水通水路)25は、冷却水を流すもので、水槽4の壁面に設けた取付穴26にパッキン27を介して挿入して着脱可能とし、この冷却ノズル25と乾燥用給水弁10とを給水ホース23により連通している。他の構成は上記実施例1〜3と同じである。
【0038】
上記構成において動作を説明する。乾燥行程で、乾燥用給水弁10から給水ホース23を介して、冷却ノズル25に通水された冷却水は水槽4の内壁面を冷やしながら流れ落ちる。これによって水槽4内の蒸気を含む高温の空気は、冷やされた水槽4の内壁面と接触し熱交換を行いながら冷却除湿される。除湿された空気はヒータ16によって再び加熱され、回転ドラム6内に送られ衣類の乾を行なうといった、一連の乾燥サイクルを形成する。
【0039】
このように本実施例によれば、冷却ノズル25内に異物などが詰まった場合、冷却ノズル25を取り外し、内部の掃除または付け換えなどの補修作業を容易に行うことができる。
【0040】
(実施例5)
図5に示すように、冷却ノズル(冷却水通水路)28、29、30は、それぞれ冷却水を流すもので、水槽4内に開口した複数個の通水孔22を有し、給水ホース31、32、33により乾燥用給水弁34、35、36に連通し、それぞれ独立した通水路を構成している。他の構成は上記実施例1と同じである。
【0041】
上記構成において動作を説明する。乾燥行程で、乾燥用給水弁34、35、36からそれぞれ給水ホース31、32、33を介して、冷却ノズル28、29、30に通水された冷却水は水槽4の内壁面を冷やしながら流れ落ちる。これによって水槽4内の蒸気を含む高温の空気は、冷やされた水槽4の内壁面と接触し熱交換を行いながら冷却除湿される。
【0042】
このとき、乾燥用給水弁34、35、36を切り換えることにより、順次冷却ノズル28、29、30への通水を切り換えることができ、一定冷却水量で水槽4の内壁面の広範囲を熱交換面として使用することができ、効率的な除湿をおこなうことができる。
【0043】
このように本実施例によれば、乾燥用給水弁34、35、36を切り換えることにより、順次冷却ノズル28、29、30への通水を切り換えることができ、節水しながら効果的に水槽4の内壁を冷却することができ、除湿性能を向上することができる。
【0044】
(実施例6)
図6に示すように、冷却ノズル(冷却水通水路)36、37は、それぞれ冷却水を流すもので、水槽4の壁面に構成し、これら冷却ノズル36、37を分岐パイプ38および給水ホース39、40を介して乾燥用給水弁41に連通し、冷却ノズル36、37への給水経路を水平面から同じ高さHとし、それぞれヘッドを同じとしている。他の構成は上記実施例1と同じである。
【0045】
上記構成において動作を説明する。乾燥行程で、乾燥用給水弁41から分岐パイプ38および給水ホース39、40を介して、冷却ノズル36、37に通水された冷却水は水槽4の内壁面を冷やしながら流れ落ちる。これによって水槽4内の蒸気を含む高温の空気は、冷やされた水槽4の内壁面と接触し熱交換を行いながら冷却除湿される。
【0046】
このとき、冷却ノズル36、37への給水経路を水平面から同じ高さHとし、それぞれヘッドを同じとすることによって、冷却ノズル36と冷却ノズル37への給水量を同じにすることができ、所定の給水量で偏りのない安定した熱交換性能を得ることができる。
【0047】
このように本実施例によれば、冷却ノズル36、37への給水経路を水平面から同じ高さHとし、それぞれヘッドを同じとすることによって、複数の冷却ノズル36、37にそれぞれ均等の水量の冷却水を流すことができる。
【0048】
(実施例7)
図7に示すように、冷却ノズル40は、冷却水を流すもので、水槽4の内壁面のドラム回転軸位置Sより下半分に冷却水を流し、水冷除湿を行うようにしている。他の構成は上記実施例1と同じである。
【0049】
上記構成において動作を説明する。乾燥行程で、乾燥用給水弁10から給水ホース23を介して、冷却ノズル40に通水された冷却水は水槽4の内壁面を冷やしながら流れ落ちる。これによって水槽4内の蒸気を含む高温の空気は、冷やされた水槽4の内壁面と接触し熱交換を行いながら冷却除湿される。
【0050】
このとき、冷却ノズル40は水槽4の内壁面のドラム回転軸位置Sより下半分に冷却水を流し、水冷除湿を行うことにより、冷却ノズル40から冷却水を自然滴下するだけの簡単な構成で、水槽4の内壁面の下半分を熱交換器として利用できる。
【0051】
(実施例8)
図8に示すように、水槽4は、壁面に冷却ノズル21を取り付け、冷却ノズル21は水槽4内に開口した複数個の通水孔22を有し、冷却ノズル21と乾燥用給水弁10とを給水ホース23により連通し、冷却ノズル21の通水孔22より水槽4の内壁に沿って冷却水を流して除湿するよう構成している。ここで、水槽4の冷却面42にシボ加工等の凹凸を複数形成している。他の構成は上記実施例1または2と同じである。
【0052】
上記構成において動作を説明する。乾燥行程で、乾燥用給水弁10から給水ホース23を介して、冷却ノズル21に通水され、複数個の通水孔22から出た冷却水は水槽4の内壁面を冷やしながら流れ落ちる。これによって水槽4内の蒸気を含む高温の空気は、冷やされた水槽4の内壁面と接触し熱交換を行いながら冷却除湿される。
【0053】
ここで、水槽4の冷却面42にシボ加工等の凹凸を複数形成しているので、水槽4の内壁面での冷却水が広がりやすくなり、熱交換面積を広げることができ、効率的な熱交換を行うことができる。
【0054】
(実施例9)
図9に示すように、冷却ノズル43は、冷却水を流すもので、水槽4の上部外壁面に構成し、この冷却ノズル43に通水経路44を連通させ、通水経路44に水槽4内に開口した開口部45を設け、冷却水を水槽4の外壁面から内壁面に連続して沿わせて流し、水冷除湿を行うようにしている。他の構成は上記実施例1と同じである。
【0055】
上記構成において動作を説明する。乾燥行程で、乾燥用給水弁10から給水ホース23を介して冷却ノズル43に通水し、通水経路44を通して、冷却水を水槽4の外壁面から内壁面に連続して沿わせて流し、開口部45より水槽4の内壁面に流れ込み、水槽4の内壁面を冷やしながら流れ落ちる。これによって水槽4内の蒸気を含む高温の空気は、冷やされた水槽4の内壁面と接触し熱交換を行いながら冷却除湿される。
【0056】
これによって、水槽4内壁面をほぼ全面にわたって、熱交換面とすることができ、熱交換面積を広くとることができて、水冷除湿能力を上げることができ、効率的な熱交換を行うことができる。
【0057】
(実施例10)
図10に示すように、冷却ノズル(冷却水通水路)46、47は、それぞれ冷却水を流すもので、水槽4の壁面に構成し、これら冷却ノズル46、47を給水ホース48、49を介して乾燥用給水弁50、51に連通し、衣類の乾燥状態に応じて乾燥用給水弁50、51の動作を切り換えるよう構成している。他の構成は上記実施例1と同じである。
【0058】
上記構成において動作を説明する。乾燥行程で、乾燥用給水弁50、51から給水ホース48、49を介して、冷却ノズル46、47に通水された冷却水は水槽4の内壁面を冷やしながら流れ落ちる。これによって水槽4内の蒸気を含む高温の空気は、冷やされた水槽4の内壁面と接触し熱交換を行いながら冷却除湿される。
【0059】
ここで、乾燥行程の予熱期間を過ぎ、水槽4内の湿度が上昇する乾燥中期において、冷却ノズル46、47の双方に乾燥給水弁50、51によってそれぞれ給水し、水槽4の内壁面を広範囲に冷却して水冷除湿を行い、乾燥後期の水槽4内の湿度が下がってくると、いずれか一方の冷却ノズルからのみの水冷とする。
【0060】
このように本実施例によれば、洗濯物からの水分の蒸発が盛んに行われる乾燥中期において効果的に水冷除湿を行うことができ、乾燥後期は洗濯物の温度過昇を抑える程度の水冷とし、使用水量を低減し、ランニングコストを抑えることができる。
【0061】
【発明の効果】
以上のように、本発明の請求項1に記載の発明によれば、水槽と回転ドラムの間の空気を冷却水によって冷却して除湿することにより、熱交換器を構成することなく、水槽内の広い空間内で除湿を行うことができ、除湿性能を向上することができるとともに、風圧による冷却水の巻き上げやリントなどの堆積による詰まりをなくすることができる。

Operations of the washing and drying processes in the above configuration will be described. When laundry is put into the rotating drum 6 and the washing process is started, the water supply valve 9 for washing is opened to supply water to the water tub 4 to a predetermined water level. Next, the rotating drum 6 is driven at a rotation speed of about 50 r / min, and the thrown clothes are repeatedly lifted and dropped by the baffle 8 and washed by the detergent water and the impact force when dropped on the water surface.
