Definitions
- the present invention relates to a novel washing method and apparatus for clothes and the like.
- ⁇ Cleaning methods are broadly divided into dry cleaning methods and wet cleaning methods. As for this cleaning method, an attempt has been made to shift the dry cleaning method to the wet cleaning method (Patent Document 1).
- This background is related to the use of organic solvents.
- the organic solvent used in dry cleaning has a large environmental load. Therefore, there are cases where legal restrictions are imposed on the use of the organic solvent itself or the amount of use thereof. For this reason, the cleaning by the dry cleaning method must be performed in consideration of the usage amount of the organic solvent and the like, and thus various restrictions are caused.
- object to be cleaned Due to such restrictions and increased awareness of environmental protection, attention has been focused on wet cleaning methods. In addition, it has become a mainstream to use a cleaning device of a wet cleaning method to clean clothes such as shirts, mufflers, and ties (hereinafter, the object to be cleaned is simply referred to as “object to be cleaned”). ing.
- drum-type cleaning devices and pulsator-type cleaning devices are used as cleaning devices that employ the wet cleaning method.
- drum-type cleaning devices and pulsator-type cleaning devices are compared, they have common features.
- the drum-type cleaning device employs a drum-type cleaning method that mainly uses tapping to make use of the height difference in the drum.
- the pulsator-type cleaning device adopts a pulsator-type cleaning method that mainly uses fir washing, which uses agitation by a rotating blade called a pulsator.
- drum-type cleaning method and the pulsator-type cleaning method which are currently used as wet cleaning methods, have the common feature of rotating and cleaning the object to be cleaned.
- this common feature due to this common feature, there are several problems that cannot be avoided with the drum-type cleaning method and the pulsator-type cleaning method.
- the first problem is that a considerable amount of damage to the fibers of the object to be cleaned occurs.
- the object to be cleaned moves violently while changing its shape, and the rotation itself also improves the cleaning effect.
- the shape and arrangement of the fibers of the object to be cleaned changes when the object to be cleaned is viewed microscopically.
- the object to be cleaned may get entangled with other objects to be cleaned, and the fibers of the object to be cleaned will be damaged or stretched.
- micro fiber changes accumulate in the object to be cleaned. As a result, the object to be cleaned may be deformed, wrinkled, rubbed or stretched.
- the second problem is that color transfer (transfer) is likely to occur.
- transfer transfer
- rotary cleaning it is inevitable that different objects to be cleaned come into contact with each other in a wet state. This often results in color transfer between different objects to be cleaned.
- the third problem is that there are objects to be cleaned that are difficult to clean and dehydrate.
- cleaning is performed while allowing moisture to penetrate between the fibers of the object to be cleaned using the centrifugal force of rotation, and dehydration is performed using the centrifugal force.
- water-repellent and waterproof objects to be cleaned cannot be washed or dehydrated because moisture does not penetrate. In this case, the water droplet traces remaining on the surface of the object to be cleaned become stains, or the color is easily transferred due to the wet state.
- the present invention has been made in view of the above problems, and an object of the present invention is to provide a new cleaning method and a cleaning apparatus that can solve these problems.

Abstract
Description
これらドラム式洗浄装置とパルセータ式洗浄装置を比較すると,それぞれに共通する特徴がある。
すなわち,ドラム式洗浄装置は,ドラム内の高低差を利用した,たたき洗いを主としたドラム式洗浄方法を採用する。一方,パルセータ式の洗浄装置は,パルセータと呼ばれる回転翼による攪拌を利用した,もみ洗いが中心となるパルセータ式洗浄方法を採用する。
回転洗浄においては,被洗浄物が形状を変えながら激しく動くとともに,その回転自体が洗浄効果を向上させることにもつながる。
しかしながら,被洗浄物が形状を変えながら激しく動くことにより,被洗浄物をミクロで見ると,被洗浄物の繊維の形状や配列に変化が起こってしまう。また,被洗浄物が,他の被洗浄物と絡まったりすることもあり,被洗浄物の繊維が傷ついたり伸びたりしてしまう。このように回転洗浄においては,ミクロな繊維の変化が,被洗浄物に蓄積してしまう。結果として,被洗浄物の型崩れやしわ,擦れや伸びなどが生じてしまうこととなる。
加えて,一旦,洗浄が終わった被洗浄物について,洗浄前の繊維の状態に完全に戻ることは無く,ミクロな繊維の変化は蓄積されたままである。そのため,再び被洗浄物を洗浄することにより,新たな洗浄により生じたミクロな変化がさらに蓄積されてしまう。結果として,回転洗浄においては,被洗浄物を繰り返し洗浄することにより,型崩れなどが不可避なものとして生じてしまうこととなる。
回転洗浄においては,異なる被洗浄物が濡れた状態で接触することが避けられない。これにより,異なる被洗浄物間で,色移りが生じてしまうことがしばしばである。
回転洗浄の場合,回転による遠心力を利用して被洗浄物の繊維の間に水分を浸透させながら洗浄を行い,遠心力を利用して脱水を行う。しかしながら,撥水加工や防水加工された被洗浄物は,水分が浸透しないため洗浄も脱水もすることができない。この場合,被洗浄物の表面に残留した水滴跡などが,シミとなったり,濡れたままの状態が続くことにより,色移りが起きやすい。
本発明の第一の構成は,被洗浄物を,上方および下方,または左側および右側などの,二方向から覆うことにより,被洗浄物を固定するための被洗浄物固定手段と,被洗浄物の洗浄を行う洗浄手段とを備え,前記被洗浄物固定手段において,通水孔を備えた固定具により被洗浄物が固定されており,前記洗浄手段は,被洗浄物に対して近接および離間が可能であり,かつ,流体の噴射機構と回収機構を備えた洗浄器具により,通水孔を備えた固定具を通じて,流体の噴射および回収を被洗浄物に対して行うことにより,被洗浄物の洗浄がなされることを特徴とする洗浄方法である。
本発明の第二の構成は,前記被洗浄物固定手段が,被洗浄物を支持するためのプレートと,前記プレートに支持された被洗浄物を反対方向から覆うことにより前記プレートとの間に被洗浄物を固定するためのカバーとによりなされることを特徴とする第一の構成に記載の洗浄方法である。
本発明の第七の構成は,前記網が,ポリテトラフルオロエチレンからなることを特徴とする第三から第六の構成に記載の洗浄装置である。
本発明の第九の構成は,第三ないし第七の構成の何れかに記載の洗浄装置に用いるための交換用カバーである。
(1) 回転洗浄と比較して,被洗浄物の繊維に対するダメージを少なくすることができる効果。
(2) 複数の被洗浄物を同時に洗浄することが無いため,被洗浄物間の色移りが生じないという効果。
(3) 回転洗浄と比較して,撥水加工や防水加工がされている被洗浄物に対しても,洗浄,脱水を行うことができるという効果。
そもそも,ドライクリーニングにおいては,有機溶剤を用いることから,被洗浄物の水溶性の汚れが落ちにくいという問題が不可避であった。本発明の洗浄方法ならびに洗浄装置は,従来,ドライクリーニングしかできなかった被洗浄物に対しても,ウェット式の洗浄を行うことが可能である。このことから,ドライクリーニングしかできなかった被洗浄物の洗浄効果を高めることができるものである。
<洗浄物固定手段>
本発明の洗浄方法では,被洗浄物を,上方および下方,または左側および右側などの,二方向から覆うことにより,被洗浄物を固定するための被洗浄物固定手段を備える。さらに洗浄物固定手段は,通水孔を備えた固定具により被洗浄物が固定される。
この被洗浄物の固定は,しわ等が生じないよう被洗浄物を固定すればよく,種々の構成ないし方法を採用することができる。例えば,図2に示すように,プレート10の上に被洗浄物を置き,その上からカバー20を被せるなどして,被洗浄物を固定すればよい。また,縦方向にプレートを設置して,被洗浄物をプレートに架け,その正面からカバーを当てるなどして,被洗浄物を固定する方法を採用してもよい。
本発明の洗浄方法では,被洗浄物の洗浄を行う洗浄手段を備え,この洗浄手段は,所定の洗浄器具により行われることを特徴とする。すなわち,洗浄器具は,被洗浄物に対して近接および離間が可能であり,かつ,流体の噴射機構と回収機構を備えている。この洗浄器具により,通水孔を備えた固定具を通じて,流体の噴射および回収を被洗浄物に対して行うことにより,被洗浄物の洗浄が行われる。
このような洗浄器具として,詳細は後述するが,図1に示すノズル30が挙げられる。
洗浄装置の例として,図1の洗浄装置1が挙げられる。この洗浄装置1は,本発明の洗浄方法ないし洗浄装置を具現化したものであり,本発明の最良の実施形態を表すものである。
まず,洗浄装置1の使用方法を説明することにより,各部の役割を説明し,その後,洗浄装置1の各構成の説明を行うこととする。
洗浄装置1を用いる使用者(以下,単に「使用者」という)は,まず,被服や毛布などの被洗浄物を,プレート10に置く。使用者は,図2のように,カバー20を被洗浄物の上部から覆い,プレート10との間で被洗浄物にしわ等が生じないように固定する。
使用者は,固定された被洗浄物に対してカバーネット22を通して,汎用の霧吹きやスプレー機(不図示)で洗浄成分を含む流体(以下,洗浄液)を噴射する。この洗浄液の噴射により,被洗浄物に付着した汚れや脂分などを溶解させる。
その後,使用者は,ノズル30の先端を上方からカバーネット22を通して被洗浄物に押し当て,被洗浄物の洗浄・仕上げを行う。この押し当てられたノズル30は,汚れ等が溶解した洗浄液の回収を行うと同時に,加工液を被洗浄物に対して噴射する。この加工液は,通常,柔軟剤や撥水剤,リンス剤,抗菌剤等を含む流体である。カバーネット22は弾力を持った網状のネットであることから,ノズル30から噴射された加工液はカバーネット22を通過して被洗浄物に接触すると同時に,この網を通して,汚れ等が溶解した洗浄液および被洗浄物に接触した加工液が回収される。結果として,被洗浄物に洗浄液や加工液が残りにくい仕組みとなっている。これに加え,本洗浄装置1では,カバー部によって被洗浄物が固定されていることもあって,被洗浄物の縮みが生じにくい仕様となっている。
この場合,使用者は,まず,ノズル30へ供給される流体として,洗浄液を選択する。使用者は,この洗浄液が供給されている状態で,ノズル30を被洗浄物に押しつけ,洗浄液を被洗浄物に接触・回収させることにより,被洗浄物の洗浄を行う。続いて,ノズル30へ供給される流体として加工液を選択し,同様の作業を行えばよい。
なお,被洗浄物に接触させる流体として,洗浄液と加工液を挙げたが,当然のことながら,流体をこれらに限定する必要はなく,被洗浄物の種類に応じた適切な流体を選択することができる。
洗浄装置1は,プレート10およびカバー20,ノズル30,流体供給部60,流体回収部70を主要な構成とし,これらがテーブル台80に一体となって備えられている。
これに加えプレート10は,テーブル台80を通して流体回収部70に接続することができる(不図示)。この流体回収部70は吸引機構を備えているため,この吸引機構により,プレート微細孔11を通じた洗浄液等の流体の回収をより効率的に行うことが可能となるという効果を有する。
図1では,洗浄装置1が,プレート10全体を覆う大きさのカバー20を有しているが,これに限定するものではない。例えば,洗浄装置1が2つ以上の複数のカバー部を有し,被服上部と被服下部をそれぞれ覆うなど,複数のカバーで被洗浄物を覆うような構成とすることもできる。
通水孔21は,ノズル30から噴射等によって供給された流体をカバー20の表側から裏側に通過させ,被洗浄物に流体を接触させるための役割に加えて,被洗浄物に接触した流体についてカバー20の裏側から表側に通過させ,ノズル30から回収できるようにするための役割を有する。これらの機能を有する限り,通水孔21について特に限定する必要はないが,カバーネット22の弾力性などを考慮し,被洗浄物の保持機能を損なわない程度の微細孔であることが望ましい。
カバーネット22は,網状のものを用いており,この網の目が通水孔としての役割を果たしている。カバーネット22の素材として,好ましくは,ポリテトラフルオロエチレンを用いることができる。これにより,化学薬品を含む流体に対する耐久性が向上するという効果を有する。
