【０００１】
【発明の属する技術分野】
本発明は、洗濯槽に給水する水または洗濯液中に含まれる遊離塩素を除去できる水浄化装置を備えた洗濯機に関するものである。
【０００２】
【従来の技術】
従来、洗濯機に給水する水道水中の遊離塩素を除去する技術は、特開平２−１３６１７０号公報、特開平６−１５４４７４号公報、特開平６−２３８０９２号公報などに記載されたものが知られている。
【０００３】
特開平２−１３６１７０号公報に記載されたものは、図１７に示すように、給水ホース１を接続した給水弁２に内部ホース３を接続し、この内部ホース３に給水経路切換部４を接続し、この給水経路切換部４により遊離塩素除去材を充填したカートリッジ（図示せず）を内蔵した遊離塩素除去装置５を通して、遊離塩素を除去した水道水を給水口部６から水槽内に給水できるように構成している。
【０００４】
特開平６−１５４４７４号公報に記載されたものは、図１８に示すように、給水ホース１を２連給水弁７に接続し、この２連給水弁７の一方に遊離塩素除去材８を充填したカートリッジ９を内蔵した遊離塩素除去装置１０を接続し、遊離塩素除去装置１０の流入口１１より入った水道水を遊離塩素除去材８を通して流出口１２より出し、遊離塩素を除去した水道水を給水口部６から水槽内に給水できるように構成している。
【０００５】
また、特開平６−２３８０９２号公報に記載されたものは、図１９に示すように、給水弁２に接続した内部ホース３を通して給水する給水経路に、遊離塩素除去材８を充填したカートリッジ１３を収納するフィルターケース１３ａを引き出し状に着脱自在に取り付け、フィルターケース１３ａを装着時には水槽内へ遊離塩素を除去した水道水を給水する構成となっている。
【０００６】
【発明が解決しようとする課題】
特開平２−１３６１７０号公報、特開平６−１５４４７４号公報に記載された構成では、遊離塩素を除去した水道水を水槽内に給水するために、給水経路を完全に切り換えることにより、すべての給水が充填されている遊離塩素除去材中を通過させることと、緻密に充填した遊離塩素除去材中を通過させるために水圧を付加することが必要である。
【０００７】
さらに、還元剤を使用したカートリッジ方式では、還元剤としては還元作用を有する粉末の亜硫酸カルシウムを主成分とし、水に難溶性のエチルセルロース等をバインダー（結合剤）として粒状化したものが使用されていた。この結果、反応機構の原理は、遊離塩素が亜硫酸カルシウムの粒状体表面に接触して反応するものであった。
【０００８】
また、粒状体を充填した構成では、水の通りやすい部分と通りにくい部分を生じ易く、水圧を付加した状態で使用していると、水の通りやすい部分が他の部分よりも多くの遊離塩素と反応するために消費して、有効成分を多く残したままショートパスを生じて遊離塩素が漏れだして寿命となっていた。
【０００９】
また、活性炭を使用したカートリッジでは、水道水中に含まれる異物による目詰まりから、流量低下を生じるとともに、活性炭中を通過する流速が増して吸着能力を越えるために遊離塩素が徐々に漏れだして短寿命となる。
【００１０】
いずれの場合においても、使用者が外から還元剤の使用寿命を視覚で認識することが不可能なために、使用回数などから寿命を予測して放置することも要求される。
【００１１】
つぎに、特開平６−２３８０９２号公報に記載された構成では、遊離塩素を除去した水道水を水槽内に給水するために、カートリッジ１３を収納したフィルターケース１３ａを装着したその部分において、水道水中に含まれる遊離塩素を除去するには、難溶性の還元剤では水道水との高い接触効率（広い接触面積）が要求されている。このことから、使用中に徐々に接触面積が小さくなり、同様に使用者が外から寿命を知ることは不可能なために、使用回数などから寿命を予測して報知することも要求される。
【００１２】
また、易溶解性の還元剤では洗濯行程からすすぎ行程の各行程にわたって所定量の還元剤を水道水中に供給することは不可能であった、あまり過剰の還元剤が洗濯液中にあると還元作用により色柄物（染料）に変色を生じさせるために、ほぼ所定量の溶出に制御することが要求される。
【００１３】
さらに、還元剤は、その使用によって、交換や補修が必要であり、洗濯機に還元剤を装填するのに、装填が行いやすいこと等の操作性も必要であり、装填された還元剤を安定的に使用できることも重要である。
【００１４】
本発明は上記課題を解決するもので、予め設定した所定量の還元剤を水道水中にあるいは洗濯液中に分散または溶解し、還元剤と遊離塩素を完全にかつ迅速に酸化還元反応させて除去し、水道水に含まれる遊離塩素の酸化作用による色柄（染料）の変退色やシルクの黄変や各種有機系の繊維表面加工材の酸化等を防止できるようにすることを目的としている。
【００１５】
【課題を解決するための手段】

【００１６】
これにより、予め設定した所定量の還元剤を水道水中にあるいは洗濯液中に分散または溶解し、還元剤と遊離塩素を完全にかつ迅速に酸化還元反応させて除去することができ、水道水に含まれる遊離塩素の酸化作用による色柄物（染料）の変退色やシルクの黄変や各種有機系の繊維表面加工材の酸化等を防止することができる。

【００３２】
【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。
【００３３】
（実施例１）
図１および図２に示すように、還元剤１４は、水に含まれる遊離塩素を還元するもので、亜硫酸カルシウムを主成分とし、水に徐溶性の結合剤により固結し、この還元剤１４を収納庫１５に収納し、この収納庫１５に蓋部１６をねじ１７により開閉可能に被着して水処理装置１８を構成している。収納庫１５内に給水口１９を設け、この給水口１９は、給水路２０を通して給水弁（給水手段）２１に連通し、還元剤１４の上方より給水できるようにしている。還元剤１４の下方に排水口２２を設け、この排水口２２は給水口部２３に連通している。この水処理装置１８を洗濯兼脱水槽（洗濯槽）２４より上方に配設している。
【００３４】
上記構成において動作を説明すると、収納庫１５内に還元剤１４を入れ、蓋部１６を閉じた状態で給水弁２１を開くと、給水路２０を通して給水口１９より還元剤１４の上方に散水される、収納庫１５の下部の排水口２２を経て、給水口部２３より洗濯兼脱水槽２４内に注水される。
【００３５】
このとき、還元剤１４の結合剤が徐々に溶解して水道水中へ、予め設定した所定量（たとえば、１〜３ｐｐｍ）の還元剤１４、すなわち、亜硫酸カルシウムの微粒子が分散放出される。水道水中に分散放出された亜硫酸カルシウム微粒子は、還元剤１４の表面から給水口部２３および洗濯兼脱水槽２４において、水道水中の酸化作用のある遊離塩素と酸化還元反応して遊離塩素を除去することができる。したがって、水道水に含まれる残留遊離塩素の酸化作用による色柄物（染料）の変退色やシルクの黄変や各種有機系の繊維表面加工材の酸化などを防止することができる。
【００３６】
このように本実施例によれば、給水経路を完全に切換えたり、カートリッジに水圧を付加する必要もなく、また、水道水との高い接触効率が要求されることがなく、予め設定した所定量の還元剤１４を水道水中にまたは洗濯液中に分散または溶解し、還元剤１４と水道水中の遊離塩素を完全に、かつ迅速に酸化還元反応させて除去することができ、水道水に含まれる遊離塩素の酸化作用による色柄物（染料）の変退色や、シルクの黄変や各種有機系の繊維表面加工材の酸化等を防止することができる。
【００３７】
なお、本実施例では、蓋１６は収納庫１５にねじ１７により開閉自在に被着しているが、収納庫１５を被着するものであれば、ねじ１７を設けていなくてもよい。また、水処理装置１７を洗濯兼脱水槽２４より上方に配設しているが、給水弁２１を開くことにより水道水を給水口１９より還元剤１４の上方に散水されればよく、洗濯兼脱水槽２４より上方に配設していなくてもよい。さらに、還元剤１４により処理した処理水を洗濯兼脱水槽２４に注水しているが、二槽式洗濯機などの洗濯槽に注水するようにしてもよい。
【００３８】
（実施例２）
図３に示すように、蓋部１６は、給水口２５から収納庫１５に供給された水を蓋部１６に当てることで整流し、還元剤１４に均一に給水するようにしている。他の構成は上記実施例１と同じである。
【００３９】
上記構成において動作を説明すると、収納庫１５への給水は給水弁２１より給水路２０を通り、給水口２５より蓋部１６に向けて噴射し、還元剤１４の上部に散水される。還元剤１４により水道水中の遊離塩素を酸化還元反応によって除去した後に、処理水は収納庫１５の下部の排水口２２を経て、給水口部２３より洗濯兼脱水槽２４内に注水される。
【００４０】
このように本実施例によれば、還元剤１４への給水を一旦蓋部１６に当てることで、給水の状態を制御し、この制御された水が還元剤１４にかかって溶出し、洗濯兼脱水槽２４に注水される水道水の中の遊離塩素濃度を所定値以下に押さえることができる。
【００４１】
（実施例３）
図４に示すように、蓋部２６は、内壁に給水口２５から供給された水を整流、分配するリブ２７を設け、給水口２５から収納庫１５に供給された水をリブ２７に当てて、還元剤１４の上部に散水するようにしている。他の構成は上記実施例１または２と同じである。
【００４２】
上記構成において動作を説明すると、収納庫１５への給水は給水弁２１より給水路２０を通り、給水口２５より蓋部２６に向けて噴射し、還元剤１４の上部に散水される。このとき、給水は蓋部２６の内壁に設けたリブ２７によって還元剤１４に片寄りなく散水され、溶解の状態を均一化することができる。還元剤１４により水道水中の遊離塩素を酸化還元反応によって除去した後に、処理水は収納庫１５の下部の排水口２２を経て、給水口部２３より洗濯兼脱水槽２４内に注水される。
【００４３】
このように本実施例によれば、還元剤１４への給水を一旦蓋部２６に当てることで、給水の状態を制御し、この制御された水が還元剤１４にかかって溶出し、洗濯兼脱水槽２４に注水される水道水の中の遊離遊離塩素濃度を所定値以下に押さえることができ、しかも、蓋部２６に設けたリブ２７によって、還元剤１４の溶解の状態を均一にすることができ、使用回数を重ねても安定して水道水処理を行うことができる。
【００４４】
なお、本実施例では、蓋部２６の内壁に設けたリブ２７として、断面でリブの形態を示しているが、このリブ２７は、蓋部２６の内面に、同心円状であったり、放射状であったり、スパイラル状であったりいろいろな形状が考えられるが、給水口２５から給水される水道水を還元剤１４上に散水し、溶解の状態を均一化するという効果においてはすへて同じである。要は還元剤１４上に散水し、溶解の状態を均一にするものであればよい。
【００４５】
（実施例４）
図５に示すように、蓋部２８は、内面の上面略中央部に上に凸のドーム２９を形成して略ドーム形状とし、給水口２５から収納庫１５に供給された水をドーム２９の中央部に当てて、還元剤１４の上部に散水するようにしている。他の構成は上記実施例１または２と同じである。
【００４６】
上記構成において動作を説明すると、収納庫１５への給水は給水弁２１より給水路２０を通り、給水口２５より蓋部２８に向けて噴射し、還元剤１４の上部に散水される。このとき、給水は蓋部２８の内面の上面略中央部に設けたドーム２９によって水の乱れを抑制し、還元剤１４に安定して散水され、溶解の状態を均一化することができる。還元剤１４により水道水中の遊離塩素を酸化還元反応によって除去した後に、処理水は収納庫１５の下部の排水口２２を経て、給水口部２３より洗濯兼脱水槽２４内に注水される。
【００４７】
このように本実施例によれば、還元剤１４への給水を一旦ドーム状に形成した蓋部２８に当てることにより、水圧による水の乱れを抑制し、給水の状態を安定化させることで、洗濯兼脱水槽２４に投入される水道水の中の遊離塩素濃度を高水圧の状態でも溶解の状態をも均一化することができる。したがって使用回数を重ねても安定して水道水処理を行うことができる。
【００４８】
（実施例５）

【００５７】
噴射された水は還元剤３１の上部に略同心円状に散水され、還元剤３１の溶解の状態を均一化することができる。還元剤３１により水道水中の遊離塩素を酸化還元反応によって除去した後に、処理水は収納庫１５の下部の排水口２２を経て、給水口部２３より洗濯兼脱水槽２４内に注水される。

【００７０】
（実施例１１）
図１２に示すように、収納庫１５を覆う蓋部１６の一部にマグネット４５を配設し、収納庫１５の一部にマグネット４５の磁力を検知する検知部４６を設けている。検知部４６は、蓋部１６が完全に閉じているとき、マグネット４５の位置を検出し、検出装置４７によって蓋部１６の閉状態を検知するように構成している。止水弁４８は、給水路２０内に設け、止水弁駆動装置４９により駆動するようにしている。他の構成は上記実施例６と同じである。
【００７１】
上記構成において動作を説明すると、検知部４６は、蓋部１６が完全に閉じているとき、マグネット４５の位置を検出し、検出装置４７によって蓋部１６の閉状態を検知し、給水路２０内に設けた止水弁４８を開く。したがって、収納庫１５への給水は給水弁２１より給水路２０を通り給水口３３を経て、蓋部１６に向けて噴射する。噴射された水は還元剤３１の上部に略同心円状に散水され、還元剤３１を均一に溶解することができる。還元剤３１により水道水中の遊離塩素を酸化還元反応によって除去した後に、処理水は収納庫１５の下部の排水口２２を経て、給水口部２３より洗濯兼脱水槽２４内に注水される。
【００７２】
蓋部１６が開いていると、マグネット４５の位置を検出し、検出装置４７によって蓋部１６の開状態を検知し、給水路２０内に設けた止水弁４８により、収納庫１５への給水を制限または停止する。
【００７３】

【００７７】
更に蓋５０が開状態になっていくと、図１３（ｂ）に示すように、ついには止水弁５３が給水路２０を閉じてしまう。このように、蓋部５０の開閉状態を検知する手段を設けなくとも、蓋部５０が開いていると、収納庫１５への給水の水圧を利用して自動的に止水弁５３を閉じることができ、収納庫１５への給水を制限または停止することができる。

【００８１】
更に蓋５０が開状態になっていくと、図１３（ｂ）に示すように、ついには止水弁５３が給水路２０を閉じてしまう。このように、蓋部５０の開閉状態を検知する手段を設けなくとも、蓋部５０が開いていると、水圧が低い場合でも自動的に止水弁５３を閉じることができ、収納庫１５への給水を制限または停止することができる。
【００８２】

Further, as disclosed in Japanese Patent Laid-Open No. 6-238092, as shown in FIG. 19, a cartridge 13 filled with a free chlorine removing material 8 is provided in a water supply path for supplying water through an internal hose 3 connected to a water supply valve 2. A filter case 13a to be stored is detachably attached in a drawer shape, and tap water from which free chlorine has been removed is supplied into the water tank when the filter case 13a is mounted.
[0006]
[Problems to be solved by the invention]
In the configuration described in Japanese Patent Laid-Open Nos. 2-136170 and 6-154474, all the water supply is performed by completely switching the water supply path in order to supply tap water from which free chlorine has been removed to the water tank. It is necessary to pass through the free chlorine removing material filled with water and to apply a water pressure in order to pass through the densely packed free chlorine removing material.
[0007]
Furthermore, in the cartridge system using a reducing agent, the reducing agent is mainly made of powdered calcium sulfite having a reducing action and granulated with water-soluble ethylcellulose or the like as a binder (binder). It was. As a result, the principle of the reaction mechanism was that free chlorine contacted and reacted with the surface of the calcium sulfite granules.
[0008]
In addition, in the structure filled with the granular material, it is easy to produce a part that is easy to pass water and a part that is difficult to pass, and when it is used with water pressure applied, the part that is easy to pass water has more free chlorine than other parts. The product was consumed to react with, and a short path was generated with a lot of active ingredients left, and free chlorine leaked out, resulting in a lifetime.
[0009]
Also, in the cartridge using activated carbon, the flow rate decreases due to clogging by foreign substances contained in tap water, and the flow rate passing through the activated carbon increases and exceeds the adsorption capacity. Life is reached.
[0010]
In any case, since it is impossible for the user to visually recognize the service life of the reducing agent from the outside, it is also required that the service life be predicted from the number of times of use and the like.
[0011]
Next, in the configuration described in Japanese Patent Application Laid-Open No. 6-238092, a filter containing a cartridge 13 for supplying tap water from which free chlorine has been removed to the water tank. - In order to remove the free chlorine contained in the tap water in the portion where the case 13a is mounted, a poorly soluble reducing agent requires a high contact efficiency (wide contact area) with the tap water. For this reason, the contact area gradually decreases during use, and similarly, it is impossible for the user to know the life from the outside. Therefore, it is also required to predict and notify the life from the number of times of use.
[0012]
In addition, with a readily soluble reducing agent, it was impossible to supply a predetermined amount of reducing agent into the tap water from the washing step to the rinsing step. If too much reducing agent is present in the washing solution, the reducing agent is reduced. In order to cause discoloration of the colored pattern (dye) by the action, it is required to control the elution to a predetermined amount.
[0013]
In addition, the reducing agent needs to be replaced or repaired depending on its use, and it is necessary to operate the loading machine so that it can be loaded easily. It is also important to be able to use it.
[0014]
The present invention solves the above problems by dispersing or dissolving a predetermined amount of a predetermined reducing agent in tap water or washing liquid, and removing the reducing agent and free chlorine by a redox reaction completely and rapidly. The purpose of the present invention is to prevent discoloration of the color pattern (dye) due to the oxidizing action of free chlorine contained in tap water, yellowing of silk, oxidation of various organic fiber surface treatment materials, and the like.
[0015]
[Means for Solving the Problems]
