Description

【0001】
【発明の属する技術分野】
本発明は、略水平方向または略傾斜方向に回転自在に配設した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5に示すように構成していた。以下、その構成について説明する。
【0003】
図5に示すように、洗濯乾燥機本体1は、内部に複数のサスペンション2とダンパー3とで水槽4を支持し、水槽4の開口部をドア5により開閉し、水槽4内に回転ドラム6を回転自在に配設し、この回転ドラム6を洗濯モータ7により駆動する。回転ドラム6に多数の通水孔8とバッフル9を設けている。洗濯乾燥機本体1に洗濯用給水弁(給水手段)10と冷却水用給水弁11を設けている。水槽4に排水口12を設け、この排水口12と排水ポンプ(排水手段)13とを排水経路14により連通している。
【0004】
水槽4内に吹き出し口15を介して送風機(送風手段)16により送風し、この送風機16にヒータ(加熱手段)17を連通し、水槽4内と送風機16とを熱交換器18により連通し、冷却水用給水弁11に直結した冷却水ホース19を熱交換器18に連通して、一連の乾燥循環経路を構成している(例えば、特許文献1参照)。
【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洗濯行程を開始すると、洗濯用給水弁10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で回転駆動し、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。洗濯行程が終わると、排水ポンプ13を駆動し、洗濯水を排水経路14を通して排水する。排水が終わると回転ドラム6を約1000r/min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。
【0006】
乾燥行程では、洗濯行程と同様に、回転ドラム6を回転駆動し、回転ドラム6内の洗濯物を撹拌しながら、送風機16とヒータ17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15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。さらに、蒸気を含む高温の空気は熱交換器18内に送られ、冷却水用給水弁11から冷却水ホース19を介して、熱交換器18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、除湿された空気はヒータ17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している。

【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、洗濯行程にて給水によって水槽4内の水位が上がり、通常水位は水位設定手段(図示せず)により冷却水ホース19の開口部より下に設定されるが、水位検知手段(図示せず)が故障したり、誤動作をすると、冷却水ホース19の水槽4側への開口部が水没する場合がある。このとき、水道管が負圧になった場合、冷却水用給水弁11に直結している冷却水ホース19を介して、洗濯水が浄水(水道水)の配管内へ侵入し、これによって浄水を汚染するという問題を引き起こすことになる。
【0009】

【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、略水平方向または略傾斜方向に回転中心軸を有する回転ドラムを水槽内に内包し、水槽の開口部にドアを設け、水槽内に給水手段により給水するとともに排水手段により水槽内の水を排水し、水槽内に送風する送風手段と加熱手段とを連通し、水槽内を除湿する除湿手段と冷却水ホースを連通し、冷却水ホースを介して除湿手段に冷却水給水手段より給水するよう構成し、冷却水ホースと除湿手段の経路の一部に貯水部を設け、貯水部を大気開放としたものである。
【0011】
これにより、冷却水ホースの開口部が水没した場合に水道管が負圧になっても、洗濯水や泡の浄水へ逆流するのを阻止することができ、浄水を汚染するのを防止することができる。

【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。
【0019】
(実施例1)
図1に示すように、貯水部20は、熱交換器(除湿手段)21に連通し、冷却水用給水弁(冷却水給水手段)11により熱交換器21に給水する冷却水ホース22の経路の一部に設け、貯水部20を大気開放としている。
【0020】
ここで、貯水部20の位置を熱交換器21より高くし、貯水部20から熱交換器21までの冷却水ホース22の引き回しを、常に徐々に低くなるようにしている。
【0021】
上記構成において作用を説明する。洗濯行程にて給水すると水槽4内の水位が上がり、水槽4と連結している熱交換器21内へ水が侵入し、熱交換器21内の水位も同時に上がる。通常水位は、水位設定手段(図示せず)により冷却水ホース22の開口部22aより下に設定されるが、水位検知手段(図示せず)が故障したり、誤動作をすると冷却ホース22の水槽4側への開口部22aが水没する場合がある。また、洗濯時に洗濯水による泡が立ちすぎると同じく開口部22aが泡に没することとなる。
【0022】
この状態で水道管23が負圧になった場合、貯水部20において冷却水ホース22は大気に開放されているため、水道管23が負圧になっても、洗濯水や泡が水道管23内へ逆流現象を起こすことがない。
【0023】
このように本実施例によれば、冷却水ホース22と熱交換器21の経路の一部に貯水部20を設け、貯水部20を大気開放としたので、冷却水ホース22の開口部22aが水没した場合に水道管23が負圧になっても、洗濯水や泡の浄水へ逆流するのを阻止することができ、浄水を汚染するのを防止することができ、衛生面で信頼性の高いドラム式洗濯機を提供することができる。
【0024】
また、貯水部20の位置を熱交換器21より高くすることによって、水道管23と冷却水用給水弁11とを直結して得られる水圧を必要とせず、ヘッドの差Hによって一定流量の冷却水を、連続的に熱交換器21に給水することができる。
【0025】
また、貯水部20から熱交換器21までの冷却水ホース22の引き回しを、常に徐々に低くなるようにすることによって、冷却水ホース22内の残水をなくし、冬季の凍結による機能障害や冷却水ホース22の破裂を防止することができる。
【0026】
(実施例2)
図2に示すように、冷却水ホース22を冷却水用給水弁11と直結し、冷却水ホース22の途中に分岐ジョイント24を取り付け、片方の経路を大気に開放したバイパス25を設けている。他の構成は上記実施例1と同じである。
【0027】
上記構成において作用を説明する。洗濯行程にて給水すると水槽4内の水位が上がり、水槽4と連結している熱交換器21内へ水が侵入し、熱交換器21内の水位も同時に上がる。通常水位は、水位設定手段(図示せず)により冷却水ホース22の開口部22aより下に設定されるが、水位検知手段(図示せず)が故障したり、誤動作をすると冷却ホース22の水槽4側への開口部22aが水没する場合がある。また、洗濯時に洗濯水による泡が立ちすぎると同じく開口部22aが泡に没することとなる。
【0028】
ここで、冷却水ホース22の途中に分岐ジョイント24を取り付け、片方の経路を大気に開放しているため、水道管23が負圧になっても、洗濯水や泡が水道管23内へ逆流現象を起こすことがない。
【0029】
このように本実施例によれば、冷却水ホース22を冷却水用給水弁11と直結し、冷却水ホース22の途中に分岐ジョイント24を取り付け、片方の経路を大気に開放したバイパス25を設けているので、水道管23が負圧になっても、冷却水ホース22内が負圧になるのを防ぐことができ、洗濯水や泡の逆流現象を阻止することができ、浄水を汚染するのを防止することができる。
【0030】
(実施例3)
図3に示すように、冷却水ホース26は、冷却水用給水弁11により複数の熱交換器21、27に給水するもので、途中で分岐させて、複数の熱交換器21、27に給水できるように構成している。
【0031】
ここで、図4に示すように、冷却水ホース26の分岐ジョイント28を左右対称に構成している。他の構成は上記実施例1または2と同じである。
【0032】
上記構成において作用を説明する。乾燥行程にて、蒸気を含む高温の空気は熱交換器21、27内に送られ、冷却水用給水弁11から冷却水ホース26を介して、熱交換器21、27内に供給された冷却水と混合し、熱交換を行い冷却除湿することができる。
【0033】
このように本実施例によれば、冷却水ホース26を途中で分岐し、複数の熱交換器21、27に給水できるように構成したので、1つの冷却水用給水弁11で複数の熱交換器21、27を機能させることができ、節水に寄与するとともに広範囲で効率的な熱交換を行うことができ、乾燥性能を向上することができる。
【0034】
また、冷却水ホース26の分岐ジョイント28を左右対称に構成しているので、複数の熱交換器21、27にそれぞれ均等量給水することができ、安定した熱交換性能を得ることができる。
【0035】
【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、冷却水ホースと除湿手段の経路の一部に貯水部を設け、貯水部を大気開放としたから、冷却水ホースの開口部が水没した場合に水道管が負圧になっても、洗濯水や泡が水道管内への逆流するのを阻止することができ、浄水を汚染するのを防止することができ、信頼性の高いドラム式洗濯乾燥機を提供することができる。

【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Components having the same configuration as the conventional example are denoted by the same reference numerals, and description thereof is omitted.
[0019]
(Example 1)
As shown in FIG. 1, the water storage unit 20 communicates with a heat exchanger (dehumidifying means) 21, and a cooling water hose 22 for supplying water to the heat exchanger 21 by a cooling water supply valve (cooling water supply means) 11. And the water reservoir 20 is open to the atmosphere.
[0020]
Here, the position of the water storage section 20 is higher than the heat exchanger 21, and the routing of the cooling water hose 22 from the water storage section 20 to the heat exchanger 21 is always gradually lowered.
[0021]
The operation of the above configuration will be described. When water is supplied during the washing process, the water level in the water tub 4 rises, water enters the heat exchanger 21 connected to the water tub 4, and the water level in the heat exchanger 21 rises at the same time. The normal water level is set below the opening 22a of the cooling water hose 22 by water level setting means (not shown), but if the water level detecting means (not shown) breaks down or malfunctions, The opening 22a to the fourth side may be submerged. In addition, if the foam due to the washing water is excessively formed during the washing, the opening 22a is also submerged in the foam.

No backflow phenomenon occurs.
[0023]
As described above, according to the present embodiment, the water reservoir 20 is provided in a part of the path between the cooling water hose 22 and the heat exchanger 21 and the water reservoir 20 is opened to the atmosphere. Even if the water pipe 23 becomes negative pressure when submerged, it is possible to prevent the washing water and the foam from flowing back to the purified water, to prevent the purified water from being polluted, and to improve the sanitary reliability. A high drum-type washing machine can be provided.
[0024]
In addition, by setting the position of the water storage section 20 higher than the heat exchanger 21, the water pressure obtained by directly connecting the water pipe 23 and the cooling water supply valve 11 is not required, and cooling at a constant flow rate is achieved by the difference H between the heads. Water can be continuously supplied to the heat exchanger 21.
[0025]
In addition, by constantly lowering the length of the cooling water hose 22 from the water storage unit 20 to the heat exchanger 21, residual water in the cooling water hose 22 is eliminated, and functional failure and cooling due to freezing in winter are prevented. The rupture of the water hose 22 can be prevented.
[0026]
(Example 2)
As shown in FIG. 2, the cooling water hose 22 is directly connected to the cooling water supply valve 11, a branch joint 24 is attached in the middle of the cooling water hose 22, and a bypass 25 having one path open to the atmosphere is provided. Other configurations are the same as those in the first embodiment.
[0027]
The operation of the above configuration will be described. When water is supplied during the washing process, the water level in the water tub 4 rises, water enters the heat exchanger 21 connected to the water tub 4, and the water level in the heat exchanger 21 rises at the same time. The normal water level is set below the opening 22a of the cooling water hose 22 by water level setting means (not shown), but if the water level detecting means (not shown) breaks down or malfunctions, The opening 22a to the fourth side may be submerged. In addition, if the foam due to the washing water is excessively formed during the washing, the opening 22a is also submerged in the foam.
[0028]
