Abstract

<P>PROBLEM TO BE SOLVED: To prevent a washing-liquid from dripping and holding up on a surface to be washed, at the beginning of operation and after the operation, and to prevent a pump as well as a liquid-supplying passage from corroding and being damaged, so as to improve the durability of a spraying washing machine. <P>SOLUTION: This invention is to wash an object by spraying a mist on it, which mist has a particle-diameter of 20-50μm and a temperature of 35-45°C. In order to carry out spraying, a pressurized washing-liquid 7 having an antibacterial or sterilizing function, is supplied to a nozzle 21 through a washing-liquid flowing passage formed by a main pipe R<SB>1</SB>, a liquid-heating unit 23, and a ditch formed on the surface of a helical block 23A which is inserted in the liquid-heating unit 23. Hot air is then delivered outwardly by virtue of an air-heater 24 and an air-fan 25, in such a manner that the mist sprayed will be wrapped up. Before the spraying operation, residual air within R<SB>1</SB>and P is extracted out, while the residual washing-liquid within R<SB>1</SB>and P is extracted after the spraying operation. Further, at the beginning of such spraying operation, the width of the aforementioned ditch is optimized so as to quickly extract out air staying between a valve V<SB>1</SB>and the nozzle by virtue of a hydraulic pressure. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
本発明は、適温の霧を洗浄対象に噴射して洗浄する霧洗浄器に関する。
【0002】
【従来の技術】
従来の霧洗浄器として、洗浄対象体に粒径50〜800μmの湯水を噴霧して洗浄する洗浄装置(例えば、特許文献1参照。)がある。この洗浄装置は前記粒径50〜800μmの湯水を噴霧するため、洗浄対象体に噴霧した湯水が流れ落ちるため浴室等の湯水が流れ落ちもよい場所でしか利用することができないという問題があった。
【0003】
また、洗浄対象体に噴霧した洗浄液が流れ落ちるのを防止するため、洗浄対象体に噴霧された洗浄液を吸引する洗浄液吸引部を設けた霧洗浄装置(例えば、特許文献2参照。)がある。この洗浄装置は洗浄対象体に噴霧する霧の粒径が大きいために洗浄液が洗浄対象体表面から液ダレし、これを吸引する手段を設けるもので、装置が大型且つ複雑となり、コストが増大とするという問題があった。
【0004】
また、洗浄液が洗浄対象体表面から液ダレしない程度の粒径100μm以内の霧を噴霧して洗浄する洗浄装置(例えば、特許文献3参照。)がある。この洗浄装置は前記粒径の霧を噴霧する噴霧口の周囲に温風又は熱線噴出口を設けて、噴霧された霧を温風で加熱、加速させて洗浄対象体に噴射するもので、汚れを落としたい場合は霧の粒径を5〜10μmにするものである。しかし、前記霧洗浄装置においては、噴霧動作開始前後、噴霧動作後に噴霧ノズルから洗浄液の液ダレが発生したり、噴霧動作停止後は、霧洗浄装置内部の洗浄液の通路となるパイプ等に洗浄液が滞留したままであるため、洗浄液の腐敗又は化学反応等により、パイプの汚染、ノズルの目詰まり、その他の機器の故障等の原因となるという問題があった。

【発明の実施の形態】
以下、本発明の実施の形態を説明する。
本発明は、洗浄作用の良好な所定の粒径及び所定の温度の霧(ミスト)を洗浄対象体に噴霧する霧洗浄器に関するものであり、好ましくは、前記粒径が20〜50μmで、霧の温度が35〜45゜Cである。
【0025】
本発明の霧洗浄器は、洗浄対象体表面に到達した霧の温度(35〜45゜C)より高温で且つ所定の洗浄液圧で所定の粒径(20〜50μm)の霧を噴射する霧発生機構と、前記霧発生機構から噴射する霧の温度以上の温風を霧の周囲を包むようにして洗浄対象物の方向に所定の風量の温風を送出する温風発生機構と、前記霧発生機構における霧の温度及び洗浄液の印加圧力、温風発生機構における風の温度及び風量、並びに前記霧発生機構及び温風発生機構の起動、停止及びバルブの開閉制御を行う制御機構と、装置の各種設定値の設定及び操作を行うための操作部と、前設定値及び装置の動作状態等を表示する表示部と、から構成される。
【0026】
前記霧発生機構は、液圧が所定値以上で且つトリガスイッチ26がオンの状態で霧をその先端から洗浄対象体の方向に噴射するノズル21と、その一端をノズル21に、他端を液供給路(主パイプ)Rに夫々接続する円筒状の洗浄液加熱ユニット(以後、液加熱ユニットという。)23と、前記液加熱ユニット23の内壁に密着して内挿され、その表面にヘリカル状の溝が形成された略円柱状のヘリカルブロック23Aと、洗浄液タンク3に蓄えられた洗浄液をポンプPの圧力によりノズル21及び洗浄液加熱ユニット23とヘリカルブロック23Aからなる洗浄液液供給路に供給する液供給路(主パイプ)Rと、その先端が液供給路Rの途中に接続し、液供給路R内に残存する洗浄液又は空気を抜くためのバイパス流路(副パイプ)Rと、液供給路Rに供給される洗浄液を所定温度に加熱する液加熱ヒータ22と、液供給路R内の洗浄液を所定の圧力に加圧するポンプPと、ノズル21への洗浄液の供給を導通又は遮断するノズル開閉バルブVと、前記液供給路Rとバイパス流路Rの分岐点に設置され、液供給路Rのノズル側、液供給路Rのポンプ側、バイパス流路R側の夫々の導通又は遮断する分岐点開閉バルブVと、液供給路Rのポンプと洗浄液タンクとの間の空気吸入孔R近傍に設けられ、液供給路Rと空気吸入孔Rの夫々の導通又は遮断する空気吸入孔開閉バルブVと、洗浄液タンク3と、から構成される。
【0027】
前記液加熱ユニット23及びヘリカルブロック23Aについて説明する。
液加熱ユニット23は、図5(b)及び(c)に示すように、その形状が円筒状で、その一端をノズル21に、他端を液供給路(主パイプ)Rに夫々接続する。そして、ヘリカルブロック23Aは、図5(a)に示すように、その形状は円柱状で、その表面に、洗浄液又は内部に滞留する空気の通路となるヘリカル状の溝が形成される。そして、ヘリカルブロック23Aは、図5(c)に示すように、前記洗浄液加熱ユニット23内にその内壁に密着して内挿される。前記溝の幅及び深さはその液圧及び溝の長さとの関係により、その値を最適値に設定することにより、洗浄液加熱ユニット23の内壁とヘリカルブロック23Aの溝とにより形成された空間内に滞留する空気を加圧された液により短時間で効率良くノズル21の先端から排出される。なお、前記ヘリカルブロック23Aを洗浄液加熱ユニット23内に挿入しない場合、又はヘリカルブロック23Aの溝の幅が広いか又は深い場合は、加圧した洗浄液で溝に滞留する空気をノズル先端から外部に排出することができないか、又は排出に時間を要すると問題が生じる。
【0028】
ポンプPは、液供給路R中の洗浄液7又は空気を液供給路R及びバイパス流路Rに送り込むためのものである。
【0029】
前記本発明のノズル21は、図1に示すように、洗浄液圧が所定値以下の時に、ノズル孔を閉じるノズルシャッター(図示省略)を設けたものを使用する。液圧が一定値以上で且つトリガスイッチがオンの状態で噴霧動作が開始されても液圧が所定値以下ではノズルシャッターは「閉」状態のため、液漏れが発生することはない。
【0030】
前記温風発生機構は、図1に示すように、所定の風量の風を送出する送風ファン25と、前記風を所定の温度に加熱する空気加熱ヒータ24と、から構成され、ノズル21の先端から噴霧する霧の周囲を取り囲むようにこの霧の温度より高温の温風を所定の速度(風量)で発生し、前記噴霧する霧を加熱し、洗浄面に向かって加速且つ拡散させる。洗浄面では霧の粒径は僅かに減少する。
【0031】
前記制御機構は、図1に示すように、マイクロコンピュータによるプログラム制御を行う制御部4からなり、制御部4は、装置全体の動作を制御するシーケンス制御部41、液供給路R内の洗浄液の液圧を制御する液制御部42、液供給路R内の洗浄液の液温を制御する液温度制御部43、前記温風発生機構の風量を制御する風量制御部44、前記温風発生機構の風温を制御する風温制御部45、前記霧発生機構に設けられたノズル開閉バルブV、分岐点開閉バルブV及び空気吸入孔開閉バルブVの開閉制御を行うバルブ制御部46から構成される。なお、制御部4は、シワートッブ2内に収納するのが望ましいが、必要に応じて、ポンプPや洗浄液タンク3が収納される本体内に収納してもよい。
【0032】
前記操作部5は、図7に示すように、装置を始動又は停止させるためのメイン・スイッチ(電源スイッチ)、霧の温度を複数の段階に設定可能な霧温度設定スイッチ、風速を複数の段階に設定可能な風速設定スイッチ、液抜き動作を行うための液抜きスイッチ等が設けられる。
【0033】
前記表示部6は、前記操作部5のスイッチの操作状態、アラーム表示等の表示を行う部分であり、操作部5がある操作パネル上に設けるか、又は別途独立して設けてもよい。
【0034】
霧洗浄器1は物理的な構成としては、シャワートップ2と本体とからなる。シャワートップ2は、図8に示すように、その先端部に温風及び霧が噴射できるように開口部が、後端部には送風に必要な空気穴が夫々設けられる。そして、シャワートップ2は、霧を洗浄対象体に噴霧する主要機構であるノズル21、液加熱ヒータ22、洗浄液加熱ユニット23、ヘリカルブロック23A、空気加熱ヒータ24、送風ファン25、ノズル開閉バルブV、ノズル21に接続する液供給路(主パイプ)Rの一部等が収納され、小型且つ軽量で手で把持可能で、把持部に設けられたトリガ・スイッチ26の操作により噴霧のオン・オフができる。
【0035】
本体(図示省略)は、ボンプP、洗浄液タンク3、分岐点開閉バルブV、空気吸入孔開閉バルブV、液供給路(主パイプ)R及びバイパス流路(副パイプ)R等かそのケース内に収納され、その上面に前記操作部5、表示部6が設けられる。更に、電源部(図示省略)は家庭用電源から電力供給を受けて、装置内の各部に必要な電圧及び電流を供給する。
【0036】
本発明の霧洗浄器の動作について、図2に示す動作フローを用いて以下に説明する。
先ず、装置の始動に先立って、操作部(操作パネル)5の風速及び霧温度を所望の値に設定する。その後、メインスイッチのオンにより、装置は動作を開始する。装置の始動により、先ず、液加熱ヒータ22が作動してノズル21の近傍のパイプ(液供給路R)内の洗浄液が加熱される。それと同時に、後述の空気抜き処理が行われる。その後、待機状態となる。
【0037】
次に、前記待機状態において、トリガスイッチ26のオンにより、送風ファン25、空気加熱ヒーター24、ポンプPの順に作動し、所望の霧の噴霧動作が開始する。その際の各バルブの開閉状態は、図6に示すように、ノズル開閉バルブVを「開」状態、分岐点開閉バルブVのバルブV21を「開」状態、同バルブV22を「開」状態、同バルブV23を「閉」状態、空気吸入孔開閉バルブVのバルブV31を「閉」状態、バルブV32を「開」状態である。洗浄期間中は、前記霧の噴霧状態が継続する。
【0038】
噴霧動作について説明する。
ノズル21に接続された液供給路R中の洗浄液7をの温度を洗浄液加熱ヒータ22により操作部5で設定された所定の値に調整し、且つ洗浄液加圧ポンプPにより同洗浄液7の液圧を操作部5で設定された所定の値に調整する。
【0039】
前記噴霧動作開始時に、送風ファン25、空気加熱ヒーター24、ポンプPの順に作動させる理由は、先ず、温風発生機構により温風をノズル21周囲から洗浄対象体方向に勢い良く発生させて、ノズル21内に残存する洗浄液を霧化し且つ消滅させ、ノズル21からの洗浄液の液ダレを防止するためである。
【0040】
そして、トリガスイッチ26のオフにより、空気加熱ヒーター24、送風ファン25、ポンプPの順に停止し、前記霧の噴霧状態が停止し、待機状態となる。前記待機状態において、操作部(操作パネル)5上の液抜きスイッチのオンにより、後述の液抜き処理が行われる。更に、前記待機状態において、メインスイッチのオフにより、洗浄液加熱ヒータ22が停止して、装置は完全な停止状態となる。
【0041】
前記噴霧動作停止時に、空気加熱ヒーター24、送風ファン25、ポンプPの順に作動させる理由は、温風発生機構による温風により、ノズル21内に残存する洗浄液(滴(しずく)程度)を霧化し且つ消滅させて、ノズル21からの洗浄液の液ダレを防止するためである。
【0042】
前記空気抜き処理は、ポンプP及び液供給路R内に残留する空気を除去するもので、図3に示すように、ポンプPにより洗浄液タンク3の洗浄液を吸入して、洗浄液を液供給路R、液供給路Rとバイパス流路Rとの分岐点、バイパス流路Rの経路で流すことにより、ポンプP及び液供給路R内に残留する空気を洗浄液タンク3に押し出し、その後、空気は洗浄液タンク3の空気穴31から外部に排出される。
【0043】
前記空気抜き処理を行う場合、図6に示すように、ノズル開閉バルブVを「閉」状態、分岐点開閉バルブVのバルブV21を「閉」状態、同バルブV22を「開」状態、同バルブV23を「開」状態、空気吸入孔開閉バルブVのバルブV31を「閉」状態、バルブV32を「開」状態にする。
【0044】
前記液抜き処理は、ポンプP及び液供給路R内に残留する洗浄液を除去するもので、図4に示すように、ポンプPと洗浄液タンク3の間の液供給路Rに設けた空気吸入孔RからポンプPの吸引力により空気を吸引し、空気を液供給路R、液供給路Rとバイパス流路Rとの分岐点、バイパス流路Rの経路で流すことにより、ポンプP及び液供給路R内に残留する洗浄液を洗浄液タンク3に排出する。
【0045】
前記液抜き処理を行う場合、図6に示すように、ノズル開閉バルブVを「閉」状態、分岐点開閉バルブVのバルブV21を「閉」状態、同バルブV22を「開」状態、同バルブV23を「開」状態、空気吸入孔開閉バルブVのバルブV31を「開」状態、バルブV32を「閉」状態にする。
【0046】
前記洗浄液は水を主成分とし、液中に抗菌又は殺菌剤を含有する液で、このような液を用いることにより、細菌等の繁殖により洗浄液が腐敗し、液供給路R、バイパス流路R、ポンプP、ノズル21、各バルブ等が損傷するのを防止すると共に、洗浄対象体を洗浄する際にも、洗浄対象体に対して抗菌又は殺菌作用を付与するという、効果を有する。
なお、洗浄液が抗菌又は殺菌作用が無い場合には、装置不使用時に洗浄液の腐敗又はぬめりの発生により、霧発生機構の洗浄液が滞留又は通過する各部材、特に、ノズル21、液供給路R、バイパス流路R、洗浄液開閉バルブV、分岐点開閉バルブV、空気吸入孔開閉バルブV、洗浄液加圧ポンプP、洗浄液タンク7等に腐蝕又は目詰まりが発生する恐れがあるので、装置の機能を長期間安定して保持するため、洗浄液は抗菌作用又は殺菌作用のあるものを用いる必要がある。
【0047】
洗浄対象体に到達する霧の条件について、以下に説明する。
霧は円錐状に噴射され、到達点での直径は20〜25cm、霧の噴射角度(中心線とのなす角度)は60度が最適条件であり、これら数値の多少増減は洗浄効果に影響を及ぼすものではない。ノズル先端から洗浄対象面迄の距離(cm)及び直径を満足するように、洗浄液の圧力及び風圧(風量)を適度に設定制御する。
【0048】
本発明の霧洗浄器1により、前記粒径が20〜50μmで、霧の温度が35〜45゜Cの霧を洗浄対象体に噴霧した場合の洗浄作用について説明する。
洗浄対象体である人間の皮膚は通常は水分含有量が略20%に保持する作用があり、適温(好ましくは、35〜45゜C)の粒径20〜50μmの霧を皮膚に噴射することにより、皮膚の内部まで水分が吸収され、水分含有量が略20%を越えるまでになり、その後、皮膚の内部まで浸透した水分は皮膚の水分含有量が略20%になるまで内部から余分な水分として皮膚表面に浮き出て外部に放出される。前記内部に浸透した余分な水分が皮膚表面に浮き出る際に、皮膚表面に付着又は存在するよごれ物質が前記余分な水分と共に浮き出る。前記よごれ物質を含んだ余分な水分は皮膚表面上で表面張力により水玉模様となり皮膚に付着した状態に留まり液ダレはしない。
【0049】
その結果、浮き出たよごれ物質を含んだ余分な水分を消毒済のガーゼ等の綺麗な吸水性の布で吸い取る(又は皮膚を傷つけることなく拭き取る)ことにより、皮膚を洗浄することができる。前記霧により洗浄する場合、霧を発生するための洗浄液の量は少量であり、装置自体も小型且つ軽量で、ポータブルなものである。従って、病院、老人の介護施設等のベットの上で簡単に人体の洗浄を行うことができる。なお、消臭、抗菌又は殺菌処理する場合にはこれらの機能を有する洗浄液を用いる。
【0050】
更に、装置の機能を長期間安定して保持するために、抗菌又は殺菌作用のある洗浄液を用いる必要がある。
【0051】
【発明の効果】
本発明の霧洗浄器は、粒径が20〜50μmで、霧の温度が35〜45゜Cの霧を洗浄対象体に噴霧するので、皮膚表面に浮き出た余分な水分と皮膚表面に付着又は存在するよごれ物質は皮膚表面上で表面張力により水玉模様となり皮膚に付着した状態に留まり液ダレを防止する。
【0052】
本発明の霧洗浄器は、噴霧動作開始前に空気抜き処理を行うことにより、ポンプ及び液供給路内に残留する空気を除去して、噴霧動作開始時に洗浄液の液圧及び液温を短時間で設定値に設定することができる。
【0053】
本発明の霧洗浄器は、ノズルにノズルシャッター及びノズル開閉バルブ等を設けることにより、ノズル先端からの液ダレを防止することができる。
【0054】

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a mist cleaning device that performs cleaning by spraying mist at an appropriate temperature onto a cleaning target.
[0002]
[Prior art]
BACKGROUND ART As a conventional mist cleaning device, there is a cleaning device for cleaning by spraying hot water having a particle size of 50 to 800 μm onto a cleaning target body (for example, see Patent Document 1). Since this cleaning device sprays the hot water having the particle diameter of 50 to 800 μm, there is a problem that the hot water sprayed onto the object to be cleaned flows down, so that it can be used only in a place such as a bathroom where the hot water flows well.
[0003]
Further, there is a mist cleaning device provided with a cleaning liquid suction unit for suctioning the cleaning liquid sprayed on the cleaning target body in order to prevent the cleaning liquid sprayed on the cleaning target body from flowing down (for example, see Patent Document 2). This cleaning device is provided with a means for sucking the cleaning liquid dripping from the surface of the cleaning object because the particle diameter of the mist sprayed on the cleaning object is large, and the device becomes large and complicated, and the cost increases. There was a problem of doing.
[0004]
Further, there is a cleaning apparatus that sprays mist having a particle diameter of 100 μm or less to the extent that the cleaning liquid does not drip from the surface of the cleaning target body (for example, see Patent Document 3). This cleaning device is provided with a hot air or hot-wire outlet around a spray port for spraying the mist having the particle diameter, and heats and sprays the sprayed mist with warm air to spray the sprayed mist onto a cleaning object. When it is desired to reduce the fog, the particle size of the fog is set to 5 to 10 μm. However, in the mist cleaning device, before and after the start of the spraying operation, a dripping of the cleaning liquid from the spray nozzle occurs after the spraying operation, and after the spraying operation is stopped, the cleaning liquid flows into a pipe or the like which is a passage of the cleaning liquid inside the mist cleaning device. Since the cleaning liquid stays still, there is a problem in that the cleaning liquid may rot or a chemical reaction may cause contamination of pipes, clogging of nozzles, failure of other devices, and the like.

[0036]
The operation of the mist cleaning device of the present invention will be described below using the operation flow shown in FIG.
First, before starting the apparatus, the wind speed and fog temperature of the operation unit (operation panel) 5 are set to desired values. Thereafter, when the main switch is turned on, the device starts operating. When the apparatus is started, first, the liquid heater 22 is operated and a pipe (liquid supply path R) near the nozzle 21 is operated. 1 The cleaning liquid in () is heated. At the same time, an air bleeding process described later is performed. Then, it will be in a standby state.
[0037]
Next, in the standby state, when the trigger switch 26 is turned on, the blower fan 25, the air heater 24, and the pump P are operated in this order, and a spray operation of a desired mist is started. At this time, the open / close state of each valve is, as shown in FIG. 1 In the "open" state, the branch point on-off valve V 2 Valve V 21 In the "open" state, the valve V 22 In the "open" state, the valve V 23 Is in the "closed" state, and the air intake opening / closing valve V 3 Valve V 31 In the "closed" state, valve V 32 Is in the “open” state.

Adjust to a value.
[0039]
At the start of the spraying operation, the reason for operating the blower fan 25, the air heater 24, and the pump P in this order is as follows. First, the hot air generating mechanism generates hot air from around the nozzle 21 toward the body to be cleaned. This is because the cleaning liquid remaining in the nozzle 21 is atomized and disappears to prevent the cleaning liquid from dripping from the nozzle 21.
[0040]
Then, when the trigger switch 26 is turned off, the air heater 24, the blower fan 25, and the pump P are stopped in this order, and the spray state of the fog is stopped, and the apparatus enters a standby state. In the standby state, a liquid draining process described later is performed by turning on a liquid draining switch on the operation unit (operation panel) 5. Further, in the standby state, when the main switch is turned off, the cleaning liquid heater 22 is stopped, and the apparatus is completely stopped.
[0041]
When the spray operation is stopped, the reason why the air heater 24, the blower fan 25, and the pump P are operated in this order is that the cleaning liquid (about drops) remaining in the nozzle 21 is atomized by the hot air generated by the hot air generating mechanism. In addition, the cleaning liquid is made to disappear to prevent dripping of the cleaning liquid from the nozzle 21.
[0042]
The air bleeding process includes a pump P and a liquid supply path R. 1 As shown in FIG. 3, the cleaning liquid in the cleaning liquid tank 3 is sucked by the pump P, and the cleaning liquid is supplied to the liquid supply path R as shown in FIG. 1 , Liquid supply path R 1 And bypass flow path R 2 Junction, bypass flow path R 2 Pump P and liquid supply path R 1 The air remaining inside is pushed out to the cleaning liquid tank 3, and then the air is discharged to the outside through the air holes 31 of the cleaning liquid tank 3.
[0043]
When performing the air bleeding process, as shown in FIG. 1 Is in the "closed" state, the branch point on-off valve V 2 Valve V 21 In the "closed" state, the valve V 22 In the "open" state, the valve V 23 Is in the “open” state, and the air intake hole opening / closing valve V 3 Valve V 31 In the "closed" state, valve V 32 To the “open” state.
[0044]
The liquid draining process includes a pump P and a liquid supply path R 1 As shown in FIG. 4, a liquid supply path R between the pump P and the cleaning liquid tank 3 1 Air intake hole R provided in 3 Is sucked by the suction force of the pump P from the 1 , Liquid supply path R 1 And bypass flow path R 2 Junction, bypass flow path R 2 Pump P and liquid supply path R 1 The cleaning liquid remaining in the inside is discharged to the cleaning liquid tank 3.
[0045]
When performing the liquid draining process, as shown in FIG. 1 Is in the "closed" state, the branch point on-off valve V 2 Valve V 21 In the "closed" state, the valve V 22 In the "open" state, the valve V 23 Is in the “open” state, and the air intake hole opening / closing valve V 3 Valve V 31 In the “open” state, valve V 32 To the "closed" state.
[0046]
The cleaning liquid is a liquid containing water as a main component and containing an antibacterial or a bactericide in the liquid. By using such a liquid, the cleaning liquid rots due to propagation of bacteria and the like, and the liquid supply path R 1 , Bypass flow path R 2 , The pump P, the nozzle 21, the valves, and the like are prevented from being damaged, and at the time of cleaning the object to be cleaned, an antibacterial or sterilizing action is imparted to the object to be cleaned.
When the cleaning liquid has no antibacterial or bactericidal action, the cleaning liquid of the mist generating mechanism stays or passes due to decay or slimming of the cleaning liquid when the apparatus is not used. 1 , Bypass flow path R 2 , Cleaning liquid opening / closing valve V 1 , Branch point open / close valve V 2 , Air intake opening and closing valve V 3 The cleaning liquid pressurizing pump P, the cleaning liquid tank 7 and the like may be corroded or clogged. In order to maintain the function of the apparatus stably for a long period of time, it is necessary to use a cleaning liquid having an antibacterial action or a sterilizing action. There is.
[0047]
The fog conditions that reach the object to be cleaned will be described below.
The fog is sprayed in a conical shape, the diameter at the point of arrival is 20-25 cm, and the spray angle of the fog (the angle formed with the center line) is optimally 60 degrees. It has no effect. The pressure and air pressure (air volume) of the cleaning liquid are appropriately set and controlled so as to satisfy the distance (cm) and the diameter from the nozzle tip to the surface to be cleaned.
[0048]
A description will be given of a cleaning action when the mist having the particle diameter of 20 to 50 μm and the mist having a temperature of 35 to 45 ° C. is sprayed on the object to be cleaned by the mist cleaning device 1 of the present invention.
Human skin, which is the object to be cleaned, usually has an action of maintaining the water content at about 20%, and sprays a mist having a particle size of 20 to 50 μm at an appropriate temperature (preferably 35 to 45 ° C.) onto the skin. As a result, moisture is absorbed to the inside of the skin until the moisture content exceeds about 20%. After that, the moisture that has penetrated to the inside of the skin becomes excessive from the inside until the moisture content of the skin becomes about 20%. It emerges as moisture on the skin surface and is released to the outside. When the excess water that has penetrated into the interior floats on the skin surface, the dirt substance attached to or present on the skin surface floats together with the excess moisture. The excess water containing the dirt substance forms a polka dot pattern on the surface of the skin due to surface tension, remains in a state of being attached to the skin, and does not drip.
[0049]
As a result, it is possible to clean the skin by sucking (or wiping without damaging the skin) excess water containing the raised dirt substance with a clean water-absorbing cloth such as disinfected gauze. When cleaning with the fog, the amount of the cleaning liquid for generating the fog is small, and the apparatus itself is small, lightweight, and portable. Therefore, the human body can be easily washed on a bed in a hospital, a care facility for the elderly, and the like. In the case of deodorizing, antibacterial or sterilizing treatment, a cleaning liquid having these functions is used.
[0050]
Furthermore, in order to maintain the function of the apparatus stably for a long period of time, it is necessary to use a cleaning liquid having an antibacterial or bactericidal action.
