Description

本発明は、静電霧化現象を利用して帯電微粒子水を生成する静電霧化装置を備えた洗濯機に関するものである。   The present invention relates to a washing machine including an electrostatic atomizer that generates charged fine particle water using an electrostatic atomization phenomenon.

従来の洗濯機としては、洗濯運転として、洗浄→すすぎ→脱水という一連の運転を行うもの、あるいは、洗浄→すすぎ→脱水→乾燥という一連の運転を行うものが知られている。後者の洗濯機は通常洗濯乾燥機と呼ばれており、特許文献１などにより知られている。   As a conventional washing machine, as a washing operation, one that performs a series of operations of washing → rinsing → dehydration, or one that performs a series of operations of washing → rinsing → dehydration → drying is known. The latter washing machine is usually called a washing / drying machine, and is known from Patent Document 1 and the like.

しかしながら、いずれのタイプの洗濯機においても、単に洗濯（洗浄→すすぎ→脱水、又は、洗浄→すすぎ→脱水→乾燥）をするだけのものにすぎず、除菌や脱臭を行うものではなかった。   However, any type of washing machine merely performs washing (washing → rinsing → dehydration or washing → rinsing → dehydration → drying) and does not perform sterilization or deodorization.

そこで、洗濯機にオゾン発生装置を設けた脱臭機能付き洗濯機が提案されており、洗濯槽内に除菌や脱臭したいものを入れてオゾンにより除菌や脱臭をするようになっている。ところが、このオゾン発生装置を設けた脱臭機能付き洗濯機は、オゾンの毒性が高いため、高温でオゾンの処理をおこなう必要があり、オゾンの毒性や高温であるため、オゾン発生装置の運転途中や運転終了直後に扉を開くと、オゾン、高温気体が洗濯槽の開口から外部に飛散し、オゾンによる毒性、あるいは高温によるやけどの危険が生じるおそれがあり、このため、運転途中や運転終了直後に扉を開くことが出来ず、衣類などの内容物をすぐに取り出すことができないという問題があり、また、オゾン発生装置の運転中に扉を開けるとオゾンの毒性ややけどの危険があるため、オゾン発生装置の運転中に扉を開けて洗濯槽内に衣類などを追加して入れて除菌や脱臭することもできないという問題がある。
特開２００４−１９４８７６号公報 Therefore, a washing machine with a deodorizing function in which an ozone generator is provided in the washing machine has been proposed, and what is desired to be sterilized and deodorized is put into a washing tub and sterilized and deodorized by ozone. However, the washing machine with a deodorizing function provided with this ozone generator has a high toxicity of ozone, so it is necessary to treat ozone at a high temperature. If the door is opened immediately after the operation ends, ozone and high-temperature gas may scatter from the opening of the washing tub to the outside, which may cause toxicity due to ozone or risk of burns due to high temperatures. There is a problem that the door cannot be opened and contents such as clothes cannot be taken out immediately, and there is a risk of ozone toxicity and burns if the door is opened while the ozone generator is in operation. There is a problem that it is not possible to disinfect or deodorize by opening the door while the generator is in operation and adding additional clothes in the washing tub.

本発明は上記の従来の問題点に鑑みて発明したものであって、洗濯物を洗濯する運転とは独立して静電霧化装置を運転して洗濯槽内にいれた衣類のような収納物を除菌、脱臭することができ、しかも、静電霧化装置の運転中や静電霧化装置運転直後であっても、扉を開けて出し入れすることができ、更に、衣類などが熱で傷むことなく除菌、脱臭ができ、更に、水洗いし難いものであっても、除菌、脱臭が効果的に行える洗濯機を提供することを課題とするものである。   The present invention has been invented in view of the above-mentioned conventional problems, and is stored like a garment that is placed in a washing tub by operating an electrostatic atomizer independently of the operation of washing laundry. It can disinfect and deodorize things, and even during operation of the electrostatic atomizer or immediately after the operation of the electrostatic atomizer, the door can be opened and removed, and clothing can be heated. It is an object of the present invention to provide a washing machine that can be sterilized and deodorized without being damaged, and can be effectively sterilized and deodorized even if it is difficult to wash with water.

上記課題を解決するために本発明に係る洗濯機は、洗濯機１に、静電霧化により帯電微粒子水を生成して洗濯槽２内に放出するための静電霧化装置３を設け、洗濯物を洗濯する運転とは独立して上記静電霧化装置３を運転する除菌・脱臭モードを備えて成ることを特徴とするものである。   In order to solve the above problems, the washing machine according to the present invention is provided with an electrostatic atomizing device 3 for generating charged fine particle water by electrostatic atomization and discharging it into the washing tub 2 in the washing machine 1. It is characterized by comprising a sterilization / deodorization mode for operating the electrostatic atomizer 3 independently of the operation for washing the laundry.

このような構成とすることで、衣類やその他の物品の除菌や脱臭、あるいは花粉のようなアレルゲン物質の除去をするに当って、これらの物品を洗濯槽２内に入れて静電霧化装置３を運転して除菌・脱臭モードとすることで、静電霧化により帯電微粒子水を生成して洗濯槽２内に放出し、ラジカルを有する帯電微粒子水により衣類やその他の物品の除菌や脱臭、あるいはこれらの物品に付着した花粉のようなアレルゲン物質を不活性化することができ、特にナノメータサイズの帯電微粒子水であるから洗濯槽２内をすみずみまで飛翔して衣類やその他の物品に付着すると衣類などの奥深くに浸透してより効果的に臭い成分やウイルス、カビ菌、アレルゲン物質の脱臭、除菌、不活性化を行うことができる。したがって、水洗いできない衣類やぬいぐるみや靴や麦わら帽子等の除菌、脱臭をしたりできる。また、一般的に、入浴などのために脱衣した衣類を洗濯機１の洗濯槽２に入れて洗濯槽２を衣類籠として利用し、翌日、洗濯槽２に入れた衣類をそのまま洗濯するようにしているが、このように、洗濯槽２を衣類籠として利用した場合に静電霧化装置３を運転することで、脱衣した汚れた衣類を洗濯槽２に入れて一晩中放置している間に、除菌、脱臭ができる。しかも、これらの静電霧化装置３を運転して除菌・脱臭モードで除菌、脱臭をおこなっている途中やあるいは静電霧化装置３の運転を停止した直後に扉４を開けても、従来のように大量のオゾンや高温気体が外に出るというようなことがないので安全である。   By adopting such a configuration, when disinfecting and deodorizing clothing and other articles, or removing allergen substances such as pollen, these articles are placed in the washing tub 2 and electrostatic atomization. By operating the apparatus 3 to enter the sterilization / deodorization mode, charged fine particle water is generated by electrostatic atomization and discharged into the washing tub 2, and the clothes and other articles are removed by the charged fine particle water having radicals. It can inactivate allergens such as fungus, deodorant, or pollen adhering to these articles, especially nanometer-sized charged fine particle water, so it flies all over the washing tub 2 for clothing and other When it adheres to the article, it penetrates deeply into clothing and the like, and can more effectively deodorize, sterilize and inactivate odor components, viruses, fungi, and allergen substances. Therefore, it is possible to disinfect and deodorize clothes, stuffed animals, shoes, straw hats, etc. that cannot be washed with water. In general, clothes removed for bathing or the like are put in the washing tub 2 of the washing machine 1 and the washing tub 2 is used as a clothing basket, and the clothes put in the washing tub 2 are washed as they are the next day. However, in this way, when the washing tub 2 is used as a clothing basket, by operating the electrostatic atomizer 3, the undressed dirty clothes are put in the washing tub 2 and left overnight. In the meantime, it can be sterilized and deodorized. Moreover, even if the door 4 is opened during the operation of the sterilization / deodorization mode in the sterilization / deodorization mode of the electrostatic atomizer 3 or immediately after the operation of the electrostatic atomizer 3 is stopped. It is safe because a large amount of ozone and high-temperature gas do not come out like in the past.

また、除菌・脱臭モード時に洗濯槽２内に送風することが好ましい。   Further, it is preferable to blow into the washing tub 2 during the sterilization / deodorization mode.

このような構成とすることで、帯電微粒子水を送風にのって洗濯槽２の隅々まで運んで衣類やその他の物品に付着すると衣類などの奥深くに浸透してより効果的に臭い成分やウイルス、カビ菌、アレルゲン物質の脱臭、除菌、不活性化を行うことができる。   By adopting such a configuration, when charged fine particle water is blown and carried to every corner of the washing tub 2 and adheres to clothing or other articles, it penetrates deeply into the clothing or the like and more effectively smells components and It can deodorize, sterilize and inactivate viruses, fungi, and allergens.

また、除菌・脱臭モード時に洗濯槽２を回動させることが好ましい。   Further, it is preferable to rotate the washing tub 2 during the sterilization / deodorization mode.

このような構成とすることで、洗濯槽２内に入れた衣類などの物品が揺動してかき回されることになり、衣類などの物品の様々な部位に帯電微粒子水を付着させて臭い成分やウイルス、カビ菌、アレルゲン物質の脱臭、除菌、不活性化を行うことができる。   By adopting such a configuration, articles such as clothes placed in the washing tub 2 are swung and stirred, and charged fine particle water adheres to various parts of the articles such as clothes and odor components and It can deodorize, sterilize and inactivate viruses, fungi, and allergens.

また、洗濯槽２の扉４の開閉検知手段５を設け、除菌・脱臭モードに設定した状態で開閉検知手段５により扉４の開に引き続き閉がなされたことを検知して一定時間静電霧化装置３を運転することが好ましい。   Further, an opening / closing detection means 5 for the door 4 of the washing tub 2 is provided, and when the sterilization / deodorization mode is set, the opening / closing detection means 5 detects that the door 4 has been opened and closed for a certain period of time. It is preferable to operate the atomizer 3.

このような構成とすることで、除菌・脱臭モードに設定した状態で、扉４の開に引き続いて閉がなされたことを検知して、洗濯槽２内に衣類などが入れられたと推定して一定時間自動的に静電霧化装置３を自動的に運転して帯電微粒子水により除菌、脱臭を行うことができ、静電霧化装置３の無駄な運転を防止できる。   By adopting such a configuration, in the state set to the sterilization / deodorization mode, it is detected that the door 4 is closed following the opening of the door 4, and it is estimated that clothes or the like have been put in the washing tub 2 Thus, the electrostatic atomizer 3 can be automatically operated for a certain period of time to be sterilized and deodorized with the charged fine particle water, and the unnecessary operation of the electrostatic atomizer 3 can be prevented.

また、洗濯槽２の扉４の開閉検知手段５と、洗濯槽２内に入れた物の重量を検知する重量検知手段を設け、除菌・脱臭モードに設定した状態で開閉検知手段５により扉４の開に引き続き閉がなされたことを検知し、且つ、重量検知手段で洗濯槽２内に入れた物の重量を検知すると、一定時間静電霧化装置３を運転することが好ましい。   In addition, an opening / closing detection means 5 for the door 4 of the washing tub 2 and a weight detection means for detecting the weight of an object placed in the washing tub 2 are provided, and the door is opened by the opening / closing detection means 5 in a state where the sterilization / deodorization mode is set. It is preferable to operate the electrostatic atomizer 3 for a certain period of time when it is detected that the closure has been made after the opening of 4 and the weight of the object placed in the washing tub 2 is detected by the weight detection means.

このような構成とすることで、静電霧化装置３を運転して除菌や脱臭をするに当って、除菌・脱臭モードに設定した状態で、扉４の開に引き続いて閉がなされ、重量検知手段により洗濯物が入っていることを検知することで、洗濯槽２内に衣類などが入れられたと判断して所定時間自動的に静電霧化装置３を運転して帯電微粒子水により除菌、脱臭が自動的に行え、静電霧化装置３の無駄な運転を防止できる。   With this configuration, when the electrostatic atomizer 3 is operated to perform sterilization and deodorization, the door 4 is opened after the door 4 is opened in the sterilization / deodorization mode. By detecting that the laundry is contained by the weight detection means, it is determined that clothes etc. are put in the washing tub 2, and the electrostatic atomizer 3 is automatically operated for a predetermined time to charge the charged particulate water. Thus, sterilization and deodorization can be automatically performed, and useless operation of the electrostatic atomizer 3 can be prevented.

本発明は、上記のように、洗濯物を洗濯する運転とは独立して上記静電霧化装置を運転する除菌・脱臭モードを備えているので、洗濯物を洗濯する運転とは独立して静電霧化装置を運転して洗濯槽内にいれた衣類のような収納物を除菌、脱臭することができ、しかも、静電霧化装置の運転中や静電霧化装置運転直後であっても、扉を開けて出し入れすることができ、更に、衣類などが熱で傷むことなく除菌、脱臭ができ、更に、水洗いし難いものであっても、除菌、脱臭が効果的にできる。   As described above, the present invention has the sterilization / deodorization mode for operating the electrostatic atomizer independently of the operation for washing the laundry, and thus is independent of the operation for washing the laundry. It is possible to sterilize and deodorize stored items such as clothes placed in the washing tub by operating the electrostatic atomizer, and during operation of the electrostatic atomizer and immediately after operation of the electrostatic atomizer However, it can be opened and removed with the door open, and it can be sterilized and deodorized without damaging clothing, etc., and even if it is difficult to wash with water, sterilization and deodorization are effective. Can be.

以下、本発明を添付図面に示す実施形態に基いて説明する。   Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

図１には洗濯機１として洗濯機能と乾燥機能を持った洗濯乾燥機と称される洗濯機１の例が示してある。   FIG. 1 shows an example of a washing machine 1 called a washing / drying machine having a washing function and a drying function as the washing machine 1.

The rotating drum 9 has a large number of small holes and is rotated by a motor 10. A water supply channel 11 and a drainage channel 12 are connected to the water tank 8.

また、図示を省略しているが、水槽８には温風又は冷風を噴出す噴出し口が設けてあり、温風又は冷風を水槽８内に噴出して回転ドラム９内の洗濯物を乾燥することができるようになっている。   Although not shown in the drawings, the water tank 8 is provided with an outlet for ejecting hot air or cold air, and hot air or cold air is ejected into the water tank 8 to dry the laundry in the rotary drum 9. Can be done.

洗濯槽２には開口１３が設けてあり、該開口１３に開閉自在に扉４が設けてある。   An opening 13 is provided in the washing tub 2, and a door 4 is provided in the opening 13 so as to be freely opened and closed.

洗濯機本体７内で且つ洗濯槽２の外部に（つまり水槽８の外部に）静電霧化装置３が設けてある。静電霧化装置３はケース１４内に入れられ、該ケース１４にはファン２６が設けてある。ケース１４には給気路１５を構成する給気ホースの一端が連通接続してあり、該給気ホースの他端が洗濯機本体７に開口して外部と連通している。また、ケース１４には放出経路１６を構成する放出ホースの一端が連通接続してあり、該放出ホースの他端が洗濯槽２の開口１３の端部に配置してあって回転ドラム９の内部に臨んでいる。   An electrostatic atomizer 3 is provided in the washing machine body 7 and outside the washing tub 2 (that is, outside the water tub 8). The electrostatic atomizer 3 is placed in a case 14 and a fan 26 is provided in the case 14. One end of an air supply hose constituting the air supply path 15 is connected to the case 14 so that the other end of the air supply hose is open to the washing machine body 7 and communicates with the outside. Further, one end of a discharge hose constituting the discharge path 16 is connected to the case 14, and the other end of the discharge hose is disposed at the end of the opening 13 of the washing tub 2, so It faces.

静電霧化装置３は、放電電極１７と、空気中の水分を結露水として生成することで放電電極１７に水を供給するための冷却手段と、放電電極１７に生成した結露水を静電霧化するために放電電極１７に高電圧を印加するための高電圧印加部１９とを備えている。   The electrostatic atomizer 3 electrostatically discharges the dew condensation water generated on the discharge electrode 17, cooling means for supplying water to the discharge electrode 17 by generating moisture in the air as dew condensation water, and the discharge electrode 17. A high voltage application unit 19 for applying a high voltage to the discharge electrode 17 for atomization is provided.

図２には本発明に用いる静電霧化装置３の概略構成図が示してある。図２に示す実施形態においてはペルチェユニット１８により冷却手段が構成してあり、冷却手段により空気中の水分を冷却して結露水を生成することで放電電極１７に水を供給するようになっている。   FIG. 2 shows a schematic configuration diagram of the electrostatic atomizer 3 used in the present invention. In the embodiment shown in FIG. 2, the Peltier unit 18 constitutes a cooling means, and water is supplied to the discharge electrode 17 by cooling the moisture in the air and generating condensed water by the cooling means. Yes.

ペルチェユニット１８は、熱伝導性の高いアルミナや窒化アルミニウムからなる絶縁板の片面側に回路を形成してある一対のペルチェ回路板２７を、互いの回路が向き合うように対向させ、多数列設してあるＢｉＴｅ系の熱電素子２８を両ペルチェ回路板２７間で挟持すると共に隣接する熱電素子２８同士を両側の回路で電気的に接続させ、ペルチェ入力リード線２９を介してなされる熱電素子２８への通電により一方のペルチェ回路板２７側から他方のペルチェ回路板２７側に向けて熱が移動するように構成したものである。更に、上記一方の側のペルチェ回路板２７の外側には冷却部２１を接続してあり、また、上記他方の側のペルチェ回路板２７の外側には放熱部２０が接続してあり、実施形態では放熱部２０として放熱フィンの例が示してある。ペルチェユニット１８の冷却部２１には放電電極１７の後端部が接続してある。   The Peltier unit 18 has a pair of Peltier circuit boards 27 each having a circuit formed on one side of an insulating plate made of alumina or aluminum nitride having high thermal conductivity, facing each other so that the circuits face each other, and arranged in multiple rows. BiTe-based thermoelectric element 28 is sandwiched between both Peltier circuit boards 27 and adjacent thermoelectric elements 28 are electrically connected by circuits on both sides, to thermoelectric element 28 made through Peltier input lead wire 29. Is configured such that heat is transferred from one Peltier circuit board 27 side toward the other Peltier circuit board 27 side. Further, a cooling unit 21 is connected to the outside of the one side Peltier circuit board 27, and a heat radiating unit 20 is connected to the outside of the other side Peltier circuit board 27. Then, an example of a heat radiating fin is shown as the heat radiating portion 20. A rear end portion of the discharge electrode 17 is connected to the cooling portion 21 of the Peltier unit 18.

放電電極１７は絶縁材料からなる筒体３０で囲まれており、筒体３０の周壁には筒体３０内外を連通する窓３０ａが設けてある。また、筒体３０の先端開口部にリング状をした対向電極２５が配設され、放電電極１７の軸心の延長線上にリング状の対向電極２５のリングの中心が位置するように放電電極１７と対向電極２５とが対向している。   The discharge electrode 17 is surrounded by a cylinder 30 made of an insulating material, and a window 30 a that communicates the inside and outside of the cylinder 30 is provided on the peripheral wall of the cylinder 30. Further, a ring-shaped counter electrode 25 is disposed at the tip opening of the cylindrical body 30, and the discharge electrode 17 is positioned so that the center of the ring of the ring-shaped counter electrode 25 is positioned on the extension line of the axial center of the discharge electrode 17. And the counter electrode 25 are opposed to each other.

上記静電霧化装置３は、ペルチェユニット１８に通電することで、冷却部２１が冷却され、冷却部２１が冷却されることで放電電極１７が冷却され、空気中の水分を結露して放電電極１７に水（結露水）を供給するようになっている。   In the electrostatic atomizer 3, when the Peltier unit 18 is energized, the cooling unit 21 is cooled, and when the cooling unit 21 is cooled, the discharge electrode 17 is cooled, and moisture in the air is condensed and discharged. Water (condensation water) is supplied to the electrode 17.

このように放電電極１７に水が供給された状態で上記放電電極１７と対向電極２５との間に高電圧を印加すると、放電電極１７と対向電極２５との間にかけられた高電圧により放電電極１７の先端部に供給された水と対向電極２５との間にクーロン力が働いて、水の液面が局所的に錐状に盛り上がり（テーラーコーン）が形成される。このようにテーラーコーンが形成されると、該テーラーコーンの先端に電荷が集中してこの部分における電界強度が大きくなって、これによりこの部分に生じるクーロン力が大きくなり、更にテーラーコーンを成長させる。このようにテーラーコーンが成長し該テーラーコーンの先端に電荷が集中して電荷の密度が高密度となると、テーラーコーンの先端部分の水が大きなエネルギー（高密度となった電荷の反発力）を受け、表面張力を超えて***・飛散（レイリー***）を繰り返してマイナスに帯電したナノメータサイズの帯電微粒子水を大量に生成するようになっている。生成された帯電微粒子水は放出経路１６を経て洗濯槽２内に放出される。この場合、静電霧化装置３の運転時にファン２６が運転され、ファン２６の運転により、
給気路１５を経て外部空気が静電霧化装置３を入れたケース１４内に入り、放出経路１６から洗濯槽２内に流れる空気流が生じるので、この空気流に乗って帯電微粒子水が回転ドラム９内に放出される。 When a high voltage is applied between the discharge electrode 17 and the counter electrode 25 in a state where water is supplied to the discharge electrode 17 in this way, the discharge electrode is caused by the high voltage applied between the discharge electrode 17 and the counter electrode 25. The Coulomb force acts between the water supplied to the distal end portion 17 and the counter electrode 25, and the liquid level of the water locally rises in a cone shape (tailor cone). When the tailor cone is formed in this way, the electric charge concentrates on the tip of the tailor cone and the electric field strength in this portion increases, thereby increasing the Coulomb force generated in this portion and further growing the tailor cone. . When the tailor cone grows like this and the charge concentrates on the tip of the tailor cone and the density of the charge becomes high, the water at the tip of the tailor cone has a large energy (repulsive force of the charge that has become dense). In response to this, a large amount of nanometer-sized charged fine particle water charged negatively by repeating splitting and scattering (Rayleigh splitting) exceeding the surface tension is generated. The generated charged fine particle water is discharged into the washing tub 2 through the discharge path 16. In this case, the fan 26 is operated during the operation of the electrostatic atomizer 3, and the operation of the fan 26
External air enters the case 14 containing the electrostatic atomizer 3 through the air supply path 15, and an air flow that flows from the discharge path 16 into the washing tub 2 is generated. It is discharged into the rotating drum 9.

また、図示を省略しているが、洗濯の際に洗濯槽２内に張られた水が放出経路１６を介して静電霧化装置３側に浸入しないような水浸入防止手段が設けてあり、水浸入防止手段としては例えは放出経路１６の洗濯槽２側の端部に開閉自在なシャッタを設けることで構成するが、必ずしもこれにのみ限定されるものではない。シャッタを設けた場合、静電霧化装置３を運転すると連動してシャッタが自動的に開となり、且つ、静電霧化装置３の運転を停止するとシャッタが自動的に閉となるように構成する。   Although not shown, there is provided water intrusion prevention means that prevents water stretched in the washing tub 2 from entering the electrostatic atomizer 3 side through the discharge path 16 during washing. For example, the water intrusion prevention means is configured by providing an openable / closable shutter at the end of the discharge path 16 on the washing tub 2 side, but is not necessarily limited thereto. When the shutter is provided, the shutter is automatically opened in conjunction with the operation of the electrostatic atomizer 3, and the shutter is automatically closed when the operation of the electrostatic atomizer 3 is stopped. To do.

上記の構成の静電霧化装置３を備えた洗濯機１は、少なくとも、通常の洗濯モードによる運転（洗浄→すすぎ→脱水→乾燥）と、この洗濯モードによる運転とは独立して静電霧化装置３を運転する除菌・脱臭モードによる運転とを備えている。   The washing machine 1 provided with the electrostatic atomizer 3 having the above-described configuration is at least electrostatic mist independent of the operation in the normal washing mode (washing → rinsing → dehydration → drying) and the operation in the washing mode. And the operation in the sterilization / deodorization mode for operating the gasification apparatus 3.

洗濯モードによる運転、除菌・脱臭モードによる運転は洗濯機１に設けた操作部（図示せず）に設けたモード選択釦を操作して選択するものである。   The operation in the washing mode and the operation in the sterilization / deodorization mode are selected by operating a mode selection button provided in an operation unit (not shown) provided in the washing machine 1.

通常の洗濯モードを選択して洗濯運転をするには従来のこの種の洗濯機と同様の運転となる。すなわち、扉４を開けて開口１３から回転ドラム９内に洗濯物を入れ、更に、洗剤を入れ、扉４を閉じて洗濯モードを指定すると、洗濯槽２に自動的に水を張り、回転ドラム９を回動して洗浄を行う。洗浄が終了すると、すすぎ運転となり、すすぎが終了すると排水して、脱水運転となる。脱水運転が終了すると乾燥運転となり、乾燥運転が終わると洗濯（本実施形態では（洗浄→すすぎ→脱水→乾燥））が完了するので、洗濯機１の運転が停止する。   To perform a washing operation by selecting a normal washing mode, the operation is the same as that of a conventional washing machine of this type. That is, when the door 4 is opened and the laundry is put into the rotary drum 9 from the opening 13, and the detergent is put, the door 4 is closed and the washing mode is designated, the washing tub 2 is automatically filled with water, and the rotary drum 9 is rotated to perform cleaning. When the cleaning is completed, the rinsing operation is performed. When the rinsing is completed, the water is drained and the dehydrating operation is performed. When the dehydrating operation is completed, the drying operation is performed, and when the drying operation is completed, the washing (in this embodiment, (washing → rinsing → dehydration → drying)) is completed, and thus the operation of the washing machine 1 is stopped.

一方、上記洗濯モードによる運転とは独立して除菌・脱臭モードによる除菌・脱臭運転を行うには、次のようにして行う。すなわち、扉４を開け、開口１３から水が存在しない常態の回転ドラム９内に衣類やその他の物品よりなる衣類や脱臭をしようとする物品を入れ、扉４を閉じて除菌・脱臭モードを指定する（除菌・脱臭モードの指定は扉４を開ける前や扉４を開けている最中でもよい）ことで、静電霧化装置３が運転される。静電霧化装置３が運転されると、前述のように帯電微粒子水を生成され、回転ドラム９内に放出され、回転ドラム９内に入れた衣類やその他の物品に付着する。帯電微粒子水はラジカルを有しているので、衣類やその他の物品の除菌や脱臭、あるいはこれらの物品に付着した花粉のようなアレルゲン物質を不活性化することができる。特に、ナノメータサイズの帯電微粒子水であるから洗濯槽２内をすみずみまで飛翔して衣類やその他の物品に付着すると衣類などの繊維の内部の奥深くに浸透してより効果的に臭い成分やウイルス、カビ菌、アレルゲン物質の脱臭、除菌、不活性化を行うことができる。   On the other hand, in order to perform the sterilization / deodorization operation in the sterilization / deodorization mode independently of the operation in the washing mode, the operation is performed as follows. That is, the door 4 is opened, clothes or other articles to be deodorized are put into a normal rotating drum 9 where water is not present from the opening 13, and the door 4 is closed to disinfect / deodorize mode. The electrostatic atomizer 3 is operated by designating (designation of the sterilization / deodorization mode may be performed before the door 4 is opened or even while the door 4 is opened). When the electrostatic atomizer 3 is operated, charged fine particle water is generated as described above, discharged into the rotating drum 9, and adheres to clothes and other articles placed in the rotating drum 9. Since the charged fine particle water has radicals, it can sterilize and deodorize clothing and other articles, or inactivate allergen substances such as pollen attached to these articles. In particular, since it is nanometer-sized charged fine particle water, when it flies through the washing tub 2 and adheres to clothing or other articles, it penetrates deep inside the fiber of clothing and other odor components and viruses. It is possible to deodorize, sterilize and inactivate fungi and allergens.

したがって、水洗いできない衣類やぬいぐるみや靴や麦わら帽子等の除菌、脱臭をしたりできる。   Therefore, it is possible to disinfect and deodorize clothes, stuffed animals, shoes, straw hats, etc. that cannot be washed with water.

また、一般的に、入浴などのために脱衣した衣類を洗濯機１の洗濯槽２に入れて洗濯槽２を衣類籠として利用し、翌日、洗濯槽２に入れた衣類をそのまま洗濯するようにしているが、本発明の洗濯機１において、洗濯槽２を衣類籠として利用し、脱衣した衣類を上記のように洗濯槽２の回転ドラム９内に入れ、除菌・脱臭モードによる除菌・脱臭運転を行うと、洗濯槽２内に入れた洗濯をする前の衣類の除菌や脱臭ができる。このように、翌日洗濯するまでの間、洗濯槽２内に脱衣した衣類を一晩入れたままにしている間に、衣類の除菌や脱臭ができるので、翌日の洗濯がより効果的に行え、また、洗濯槽２内に臭いが蓄積したり、細菌が繁殖したりするのを確実に防止することができる。   In general, clothes removed for bathing or the like are put in the washing tub 2 of the washing machine 1 and the washing tub 2 is used as a clothes basket, and the clothes put in the washing tub 2 are washed as they are the next day. However, in the washing machine 1 of the present invention, the laundry tub 2 is used as a clothing basket, and the clothes that have been undressed are placed in the rotating drum 9 of the laundry tub 2 as described above, and the sterilization / deodorization mode is performed. When the deodorizing operation is performed, sterilization and deodorization of the clothes before washing put in the washing tub 2 can be performed. In this way, the clothes can be sterilized and deodorized while the clothes removed in the washing tub 2 are kept overnight until washing the next day, so that the next day can be washed more effectively. Moreover, it is possible to reliably prevent odors from accumulating in the washing tub 2 and bacterial growth.

ここで、洗濯機１に扉４の開閉検知手段５を設け、除菌・脱臭モードに設定した状態で、扉４の開を開閉検知手段５により検知し、引き続き閉を検知すると、静電霧化装置３を一定時間運転し、一定時間経過後に運転を停止して除菌・脱臭モードの運転を終了するようにしてもよい。このようにすることで、除菌・脱臭モードに設定していても、扉４が開いている時は静電霧化装置３の運転を休止して無駄な運転をしないようにし、また、除菌・脱臭モードに設定した状態で、一人が扉４を開いて脱衣した衣類を入れ、扉４を閉じると、一定時間だけ静電霧化装置３を運転して除菌、脱臭をし、次に、別の人が扉４を開いて脱衣した衣類を入れ、扉４を閉じると、同様に一定時間だけ静電霧化装置３が運転して除菌、脱臭をするというように、時間をあけて脱衣した衣類が次々と入れられるように場合に対応することができる。   Here, in the state where the opening / closing detection means 5 of the door 4 is provided in the washing machine 1 and the sterilization / deodorization mode is set, the opening / closing detection means 5 detects the opening of the door 4, and when the opening is continuously detected, It is also possible to operate the gasification apparatus 3 for a certain period of time, stop the operation after the lapse of a certain period of time, and end the operation in the sterilization / deodorization mode. In this way, even when the sterilization / deodorization mode is set, when the door 4 is open, the operation of the electrostatic atomizer 3 is stopped so that the wasteful operation is not performed. With the fungus / deodorization mode set, one person opened the door 4 and put on undressed clothes. When the door 4 was closed, the electrostatic atomizer 3 was operated for a certain period of time to disinfect and deodorize. In addition, when another person opens the door 4 and puts off clothes, and closes the door 4, the electrostatic atomizer 3 operates for a certain period of time to disinfect and deodorize. It is possible to deal with cases where clothes that are opened and undressed are put one after another.

上記例の場合、扉４の開を検知し、引き続き閉を検知することで、洗濯槽２内に衣類が入れられたと推定し、この推定に基づいて静電霧化装置３を運転するようにしているが、洗濯槽２内に衣類が入れられたことをより確実に検知して静電霧化装置３を運転するように、洗濯槽２の扉４の開閉検知手段５と、洗濯槽２内に入れた物の重量を検知する重量検知手段を設け、除菌・脱臭モードに設定した状態で、扉４の開に引き続き閉がなされたことを検知した後、重量検知手段で洗濯槽２内に入れた物の重量を検知すると、一定時間静電霧化装置３を運転するようにしてもよい。   In the case of the above example, by detecting the opening of the door 4 and subsequently detecting the closing, it is estimated that clothes have been put in the washing tub 2, and the electrostatic atomizer 3 is operated based on this estimation. However, the opening / closing detection means 5 of the door 4 of the washing tub 2 and the washing tub 2 so as to more reliably detect that clothes have been put in the washing tub 2 and operate the electrostatic atomizer 3. The weight detection means for detecting the weight of the object put in the inside is provided, and in the state set to the sterilization / deodorization mode, it is detected that the door 4 has been opened continuously, and then the washing tub 2 is detected by the weight detection means. If the weight of the object put in is detected, you may make it drive the electrostatic atomizer 3 for a fixed time.

この場合は、静電霧化装置３を運転して除菌や脱臭をするに当って、扉４を開に引き続いて閉がなされ、重量検知手段により洗濯物が入っていることを検知することで、洗濯槽２内に衣類などが入れられたと判断して所定時間自動的に静電霧化装置３を運転して帯電微粒子水により除菌、脱臭が自動的に行え、静電霧化装置３の無駄な運転を防止できる。   In this case, when the electrostatic atomizer 3 is operated to perform sterilization and deodorization, the door 4 is opened and subsequently closed, and the weight detection means detects that the laundry is contained. Thus, it is determined that clothes etc. have been put in the washing tub 2, and the electrostatic atomizer 3 is automatically operated for a predetermined time to be sterilized and deodorized automatically by the charged fine particle water. 3 wasted operation can be prevented.

上記した各実施形態に示す除菌・脱臭モードの運転時に洗濯槽２の一構成部材である回転ドラム９を回動運転するようにしてもよい。この場合の回動運転は一方向にのみ回動してもよく、往復回動してもよい。このように回転ドラム９内に帯電微粒子水を放出する際に同時に衣類やその他の物品を入れた状態で回転ドラム９を回動することで、回転ドラム９内に入れた衣類やその他の物品が回転ドラム９内でかき回され、衣類やその他の物品の隅々まで帯電微粒子水を付着させることができる。   The rotating drum 9, which is a constituent member of the washing tub 2, may be rotated during operation in the sterilization / deodorization mode shown in each of the above embodiments. In this case, the rotation operation may be performed only in one direction, or may be performed reciprocally. As described above, when the charged fine particle water is discharged into the rotating drum 9, the rotating drum 9 is rotated while the clothes and other articles are simultaneously put therein, so that the clothes and other articles placed in the rotating drum 9 are removed. It is stirred in the rotating drum 9, and charged fine particle water can adhere to every corner of clothes and other articles.

また、上記した各実施形態に示す除菌・脱臭モードの運転時にファン２６を同時に運転することで、帯電微粒子水が回転ドラム９内の隅々まで送って回転ドラム９内に入れた物品の隅々まで帯電微粒子水を付着させることができ、また、回転ドラム９の小孔を通して水槽８まで帯電微粒子水を至らせることができ、回転ドラム９の外面や水槽８の内面の除菌、脱臭ができる。この場合、図示を省略しているが、ファン２６で供給する送風をヒータにより加熱して温風とし、温風に乗せて帯電微粒子水を回転ドラム９内に放出するようにしてもよい。すなわち、静電霧化装置３を運転して放電電極１７に高電圧を印加して帯電微粒子水を生成する際、微量ではあるがオゾンが発生する。このオゾンは人体に悪影響を与えるので分解する必要があるが、温風を発生させることで帯電微粒子生成の際に僅かに生成されるオゾンの分解が早くなる。   Further, by simultaneously operating the fan 26 during the sterilization / deodorization mode operation shown in each of the above-described embodiments, the charged fine particle water is sent to every corner of the rotary drum 9 and is put into the corner of the article. The charged fine particle water can be attached to the water tank, and the charged fine particle water can be brought to the water tank 8 through the small hole of the rotating drum 9, so that the outer surface of the rotating drum 9 and the inner surface of the water tank 8 can be sterilized and deodorized. it can. In this case, although not shown, the air supplied by the fan 26 may be heated by a heater to be warm air, and the charged fine particle water may be discharged into the rotating drum 9 by being put on the warm air. That is, when the electrostatic atomizer 3 is operated and a high voltage is applied to the discharge electrode 17 to generate the charged fine particle water, ozone is generated although the amount is small. This ozone has an adverse effect on the human body and needs to be decomposed. However, by generating warm air, the ozone generated slightly during the generation of charged fine particles is accelerated.

前述の実施形態においては、静電霧化装置３を備えた洗濯機１が、少なくとも、通常の洗濯モードによる運転（洗浄→すすぎ→脱水→乾燥）と、この洗濯モードによる運転とは独立して静電霧化装置３を運転する除菌・脱臭モードによる運転とを備えている例で説明したが、洗濯モードによる運転が、洗浄→すすぎ→脱水→乾燥→静電霧化装置３による除菌・脱臭を一連の運転として自動的に行うもの、又は、静電霧化装置３による除菌・脱臭→洗浄→すすぎ→脱水→乾燥を一連の運転として自動的に行うもであってもよい。もちろん、洗浄モードが上記のような運転の場合であっても、これらの洗浄モードによる運転とは別に、独立して静電霧化装置３を運転する除菌・脱臭モードによる運転を備えている。   In the above-described embodiment, the washing machine 1 including the electrostatic atomizer 3 is independent of at least the operation in the normal washing mode (washing → rinsing → dehydration → drying) and the operation in the washing mode. Although the example provided with the operation in the sterilization / deodorization mode for operating the electrostatic atomizer 3 has been described, the operation in the washing mode is performed by washing → rinsing → dehydration → drying → sterilization by the electrostatic atomizer 3 A device that automatically performs deodorization as a series of operations, or a device that performs sterilization / deodorization by the electrostatic atomizer 3 → cleaning → rinsing → dehydration → drying may be automatically performed as a series of operations. Of course, even in the case where the cleaning mode is the operation as described above, the operation in the sterilization / deodorization mode in which the electrostatic atomizer 3 is operated independently is provided separately from the operation in these cleaning modes. .

また、上記各実施形態においては洗濯機１として洗濯機能と乾燥機能を持った洗濯乾燥機と称される洗濯機１の例で説明したが、洗濯機１として洗濯機能のみを持った洗濯機において、洗濯（洗浄→すすぎ→脱水）という洗濯モードによる運転とは独立して静電霧化装置３を運転する除菌・脱臭モードによる運転とを備えているものであってもよい。   In each of the above embodiments, the washing machine 1 is described as an example of the washing machine 1 called a washing / drying machine having a washing function and a drying function. However, the washing machine 1 is a washing machine having only a washing function. In addition, an operation in the disinfection / deodorization mode in which the electrostatic atomizer 3 is operated independently of the operation in the washing mode of washing (washing → rinsing → dehydration) may be provided.

なお、添付図面に示す実施形態では放電電極と対向電極との間に高電圧を印加して帯電微粒子水を生成する静電霧化装置３の例を示したが、対向電極を設けない場合であってもよい。   In the embodiment shown in the attached drawings, an example of the electrostatic atomizer 3 that generates charged fine particle water by applying a high voltage between the discharge electrode and the counter electrode is shown. There may be.
