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有する洗濯機に関するものである。   The present invention relates to a washing machine having 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ができないという問題がある。   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 the door cannot be opened while the generator is in operation, and clothes and the like can be additionally placed in the washing tub so that it cannot be sterilized or deodorized.

また、洗濯機にオゾン発生装置を設けて洗濯槽内にオゾンを放出しようとする場合、洗濯槽内へのオゾンの放出部から洗浄水がオゾン発生装置に浸入し、漏電等のトラブルが発生するおそれがある。
特開2004−194876号公報
In addition, when an ozone generator is installed in the washing machine to release ozone into the washing tub, washing water enters the ozone generator from the ozone discharge section into the washing tub, causing problems such as electric leakage. There is a fear.

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、洗濯物の殺菌、脱臭が効果的にでき、また、洗浄水が静電霧化装置に浸入して電気的トラブルを発生するのを防止でき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-described conventional problems, and can effectively sterilize and deodorize laundry, and the washing water enters the electrostatic atomizer and causes electrical trouble. It is an object of the present invention to provide a washing machine that can prevent this.

上記課題を解決するために本発明に係る洗濯機は、洗濯機本体7内に設けた洗濯槽2に洗濯物入れて洗濯する洗濯機1に、放電電極17の冷却で放電電極17に空気中の水分を結露水として生成してこの結露水を静電霧化すること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、静電霧化装置3の帯電微粒子水の洗濯槽2への放出部6に開閉自在なシャッタ5を設け、該シャッタ5が静電霧化装置3の運転中にのみ開となり、且つ、運転を停止すると閉となるように駆動手段を制御する制御部を設けて成ることを特徴とするものである Washing machine according to the present invention in order to solve the above problems, a washing machine to the washing machine 1 to the laundry put laundry into the washing tub 2 provided in the main body 7, in the air to the discharge electrode 17 by cooling the discharge electrode 17 An electrostatic atomizer 3 is provided for generating water as condensed water and electrostatically atomizing the condensed water to generate charged fine particle water and releasing it into the washing tub 2. A shutter 5 that can be freely opened and closed is provided in the discharge part 6 of the charged fine particle water to the washing tub 2 so that the shutter 5 is opened only during the operation of the electrostatic atomizer 3 and is closed when the operation is stopped. Further, a control unit for controlling the driving means is provided .

洗濯槽2内で洗浄運転をする際にはシャッタ5を閉じて放出部6から静電霧化装置3内に、洗浄水が浸入しないようにでき、また、静電霧化装置3を運転する時は、シャッタ5を開いて放出部6から帯電微粒子水を洗濯槽2内に放出して、洗濯物や洗濯槽2に付着させて除菌、脱臭ができる。   When the washing operation is performed in the washing tub 2, the shutter 5 can be closed so that the washing water does not enter the electrostatic atomizer 3 from the discharge unit 6, and the electrostatic atomizer 3 is operated. When the shutter 5 is opened, the charged fine particle water is discharged from the discharge portion 6 into the washing tub 2 and attached to the laundry or the washing tub 2 so that sterilization and deodorization can be performed.

本発明は、上記のように、静電霧化装置の帯電微粒子水の洗濯槽への放出部に開閉自在なシャッタを設けてあるので、静電霧化装置を運転して帯電微粒子水により洗濯物や洗濯槽の除菌、脱臭が効果的にでき、また、洗浄運転をする際の洗浄液が静電霧化装置に浸入するのを防止して電気的トラブルが発生しないようにできる。   In the present invention, as described above, a shutter that can be freely opened and closed is provided at the discharge portion of the electrostatic atomizer to the washing tub of charged fine particle water. It is possible to effectively sterilize and deodorize objects and washing tubs, and to prevent the cleaning liquid during the cleaning operation from entering the electrostatic atomizer so that no electrical trouble occurs.

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.

洗濯機1の外郭を構成する洗濯機本体7内には洗濯槽2が内装してあり、洗濯槽2は内部に回転ドラム9を配置した水槽8により構成してある。回転ドラム9は多数の小孔を形成してあり、モータ10により回動するようになっている。水槽8には給水路11、排水路12が接続してある。   A washing tub 2 is housed inside a washing machine main body 7 constituting the outline of the washing machine 1, and the washing tub 2 is constituted by a water tub 8 in which a rotating drum 9 is arranged. 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、表面張力を超えて分裂・飛散(レイリー分裂)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 by the operation of the fan 26, external air enters the case 14 containing the electrostatic atomizer 3 through the air supply path 15, and the discharge path. Since an air flow that flows into the washing tub 2 from 16 is generated, the charged fine particle water is discharged into the rotating drum 9 along the air flow.

また、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にするための開閉自在なシャッタ5が設けてある。このシャッタ5は駆動手段により開閉駆動するもので、静電霧化装置3を運転すると連動してシャッタ5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5が自動的に開となるように制御部により制御されるようになっている。   Further, an openable / closable shutter 5 is provided to prevent water stretched in the washing tub 2 during washing from entering the electrostatic atomizer 3 via the discharge path 16. The shutter 5 is opened and closed by a driving means. When the electrostatic atomizer 3 is operated, the shutter 5 is automatically opened. When the electrostatic atomizer 3 is stopped, the shutter 5 is opened. It is controlled by the control unit so as to be automatically opened.

上記の構成の静電霧化装置3を備えた洗濯機1は、例えば、洗濯物を洗濯処理する洗濯運転として少なくとも2つの洗濯運転モードを有している。   The washing machine 1 provided with the electrostatic atomizer 3 having the above-described configuration has, for example, at least two washing operation modes as a washing operation for washing the laundry.

第1の洗濯運転モードは図3のフロー図に示すようなもので、一連の洗濯運転として、洗浄(洗濯物の洗浄運転)→すすぎ(洗濯物のすすぎ運転)→脱水(洗濯物の脱水運転)→乾燥(洗濯物の乾燥運転)→除菌・脱臭(静電霧化装置3の運転)の順番で運転するモードである。   The first washing operation mode is as shown in the flow chart of FIG. 3. As a series of washing operations, washing (washing operation of laundry) → rinsing (rinsing operation of laundry) → dehydration (dehydration operation of laundry) ) → drying (drying operation of the laundry) → sterilization / deodorization (operation of the electrostatic atomizer 3).

また、第2の洗濯運転モードは図4のフロー図に示すようなもので、一連の洗濯運転として、洗浄(洗濯物の洗浄運転)→すすぎ(洗濯物のすすぎ運転)→脱水(洗濯物の脱水運転)→除菌・脱臭(静電霧化装置3の運転)の順番で運転するモードであり、いずれかの運転モードを洗濯して指定することで制御部により自動的に運転がなされる。
上記洗濯運転モードは洗濯機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して指定するものである。
Further, the second washing operation mode is as shown in the flow chart of FIG. 4. As a series of washing operations, washing (washing washing operation) → rinsing (washing washing operation) → dehydration (laundry washing) Dehydration operation) is a mode that operates in the order of sterilization / deodorization (operation of electrostatic atomizer 3), and is automatically operated by the control unit by washing and specifying one of the operation modes. .
The washing operation mode is selected and designated by operating a mode selection button provided in an operation unit (not shown) provided in the washing machine 1.

本発明の洗濯機1により洗濯をするに当っては、まず、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を閉じて洗濯運転モードを指定する。ここで、第1の洗濯運転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を回動して洗浄運転を行い、洗浄運転が終了すると、すすぎ運転となり、すすぎ運転が終了すると排水して、脱水運転となり、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除菌・脱臭運転となり(この場合、静電霧化装置3の運転が開始されると同時にシャッタ5が自動的に開となる)、帯電微粒子を生成して洗濯槽2内に帯電微粒子水を放出し、一定時間後の静電霧化装置3の運転が終了すると同時にシャッタ5が自動的に閉となり除菌・脱臭運転が終了すると、第1の洗濯運転モードによる一連の洗濯運転が停止する。   When washing with the washing machine 1 of the present invention, first, the door 4 is opened, the laundry is put into the rotating drum 9 through the opening 13, and the detergent is further closed, the door 4 is closed and the washing operation mode is set. specify. Here, when the first washing operation mode is designated, the washing tub 2 is automatically filled with water, the rotating drum 9 is rotated to perform the washing operation, and when the washing operation is completed, the rinsing operation is performed, and the rinsing operation is performed. When the operation is completed, the water is drained and the dehydration operation is completed. When the dehydration operation is completed, the operation is performed as a drying operation. When the drying operation is completed, the operation is performed as a sterilization / deodorization operation. Automatically opens), discharges charged fine particle water into the washing tub 2, and automatically closes the shutter 5 at the same time as the operation of the electrostatic atomizer 3 after a certain period of time is completed. When the sterilization / deodorization operation ends, a series of washing operations in the first washing operation mode is stopped.

また、第2の洗濯運転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を回動して洗浄運転を行い、洗浄運転が終了すると、すすぎ運転となり、すすぎ運転が終了すると排水して、脱水運転となり、脱水運転が終了すると除菌・脱臭運転となり(この場合、静電霧化装置3の運転が開始されると同時にシャッタ5が自動的に開となる)、帯電微粒子を生成して洗濯槽2内に帯電微粒子水を放出し、一定時間後の静電霧化装置3の運転が終了すると同時にシャッタ5が自動的に閉となり除菌・脱臭運転が終了すると、第2の洗濯運転モードによる一連の洗濯運転が停止する。   When the second washing operation mode is designated, the washing tub 2 is automatically filled with water, the rotating drum 9 is rotated to perform the washing operation, and when the washing operation is completed, the rinsing operation is completed and the rinsing operation is completed. Then, the water is drained and the dehydration operation is performed. When the dehydration operation is completed, the sterilization / deodorization operation is performed (in this case, the operation of the electrostatic atomizer 3 is started, and the shutter 5 is automatically opened). When the fine particle is generated and the charged fine particle water is discharged into the washing tub 2 and the operation of the electrostatic atomizer 3 after a certain time is finished, the shutter 5 is automatically closed and the sterilization / deodorization operation is finished. A series of washing operations in the second washing operation mode is stopped.

上記いずれの洗濯運転モードで運転しても、一連の洗濯運転モードの最後の段階で静電霧化装置3を運転して帯電微粒子水により回転ドラム9内の乾燥又は脱水が終わった洗濯物の除菌・脱臭を行うことになる。   Regardless of the washing operation mode, the electrostatic atomizer 3 is operated at the last stage of the series of washing operation modes, and the laundry that has been dried or dewatered in the rotating drum 9 by the charged fine particle water is finished. It will be sterilized and deodorized.

上記いずれの洗濯運転モードの場合も、シャッタ5は静電霧化装置3が運転している間のみ開で、静電霧化装置3を運転していないときは閉となるように制御されるので、静電霧化装置3を運転していないとき(洗浄運転、すすぎ運転、乾燥運転等の場合)はシャッタ5が閉じていて、放出部6から静電霧化装置3側に洗浄水などが浸入することがないようになっている。したがって、洗濯機1に静電霧化装置3を設けて帯電微粒子水で洗濯槽2内の洗濯物の除菌、脱臭をするようにしたにもかかわらず、洗浄水が静電霧化装置3に浸入して電気的トラブルを発生させないようになっている。   In any of the washing operation modes described above, the shutter 5 is controlled to be opened only while the electrostatic atomizer 3 is in operation, and closed when the electrostatic atomizer 3 is not in operation. Therefore, when the electrostatic atomizer 3 is not operated (in the case of cleaning operation, rinsing operation, drying operation, etc.), the shutter 5 is closed, and the cleaning water or the like is discharged from the discharge unit 6 to the electrostatic atomizer 3 side. Will not invade. Therefore, even though the electrostatic atomizer 3 is provided in the washing machine 1 and the laundry in the washing tub 2 is sterilized and deodorized with the charged fine particle water, the washing water is discharged from the electrostatic atomizer 3. So that it does not cause electrical trouble.

上記実施形態において、洗濯運転モードの最後の段階で静電霧化装置3を運転すると、帯電微粒子が生成され、回転ドラム9内に放出され、回転ドラム9内を隅々まで浮遊して乾燥又は脱水が終わった洗濯物に付着し、帯電微粒子水はラジカルを有しているので、洗濯物の除菌や脱臭をすることができる。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洗濯物の繊維の内部の奥深くに浸透してより効果的に脱臭、除菌を行うことができる。   In the above embodiment, when the electrostatic atomizer 3 is operated at the final stage of the washing operation mode, charged fine particles are generated and discharged into the rotating drum 9, and are floated in the rotating drum 9 and dried or dried. Since the charged fine particle water adheres to the laundry after dehydration and has radicals, the laundry can be sterilized and deodorized. In particular, since it is a nanometer-sized charged fine particle water, it can fly through the washing tub 2 and penetrate deep into the inside of the laundry fibers, thereby more effectively deodorizing and sterilizing.

上記洗濯運転の最後に行われる除菌・脱臭運転の際に、洗濯物が入っている回転ドラム9を回動運転しながら帯電微粒子を回転ドラム9内に放出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洗濯物が入っている状態で回転ドラム9を回動することで、回転ドラム9内に入れた洗濯物が回転ドラム9内でかき回され、洗濯物の隅々まで帯電微粒子水を付着させることができる。   In the sterilization / deodorization operation performed at the end of the washing operation, the charged fine particles may be discharged into the rotating drum 9 while rotating the rotating drum 9 containing the laundry. In this case, the rotation operation may be performed only in one direction, or may be performed reciprocally. Thus, when the charged fine particle water is discharged into the rotary drum 9, the laundry put in the rotary drum 9 is rotated in the rotary drum 9 by rotating the rotary drum 9 while the laundry is in the same state. The charged fine particle water can be adhered to every corner of the laundry.

また、上記洗濯運転の最後に行われる除菌・脱臭運転の際に、ファン26を同時に運転することで、帯電微粒子水を回転ドラム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。この場合、発生するオゾンの量が微量であるため温風の風量が少なくてよく、また、温度も比較的低い音風でよい。   Further, in the sterilization / deodorization operation performed at the end of the washing operation, the fan 26 is operated at the same time so that charged fine particle water is sent to every corner of the rotary drum 9 and is put into the rotary drum 9. The charged fine particle water can be adhered to every corner of the rotary drum 9, and the charged fine particle water can be brought to the water tank 8 through the small hole of the rotary drum 9. Deodorized. 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 charged fine particle water, ozone is generated although it is a small amount, but generation of charged fine particles by generating warm air. In this case, ozone that is slightly generated is decomposed quickly. In this case, since the amount of generated ozone is very small, the amount of warm air may be small, and the sound wind may be a relatively low temperature.

なお、上記実施形態では、洗濯機1に第1の洗濯運転モードと第2の洗濯運転モードとを設け、一連の洗濯運転モードの一段階として静電霧化装置3を運転して除菌・消臭運転を行う例を示したが、洗浄運転モードとは独立して静電霧化装置3を運転して除菌・消臭運転を行うようにしてもよく、この場合も、静電霧化装置3の運転中のみシャッタ5が開となり、静電霧化装置3の運転停止中はシャッタ5が閉となるように制御される。   In the above embodiment, the washing machine 1 is provided with the first washing operation mode and the second washing operation mode, and the electrostatic atomizer 3 is operated as one stage of a series of washing operation modes to disinfect Although an example in which the deodorizing operation is performed is shown, the sterilization / deodorizing operation may be performed by operating the electrostatic atomizer 3 independently of the cleaning operation mode. Control is performed so that the shutter 5 is opened only during the operation of the generator 3 and the shutter 5 is closed while the operation of the electrostatic atomizer 3 is stopped.

次に、他の実施形態を図5に基づいて説明する。本実施形態は、静電霧化装置3を洗濯機本体7の洗濯槽2とは別の場所(図5の実施形態では洗濯槽2の上方)に配置してあり、放出経路16により静電霧化装置3と洗濯槽2とを連通してある。放出経路16は上下方向に蛇行しており、谷16a部分の底に排水手段23を構成する排水小孔23aが設けてあり、該排水小孔23aには排水管23bの一端が接続してあって、上下に蛇行した放出経路16の谷16a部分に水が溜まった場合、排水管23bを介して洗濯槽2内又は排水路12に排水するようになっている。   Next, another embodiment will be described with reference to FIG. In the present embodiment, the electrostatic atomizer 3 is disposed at a location different from the washing tub 2 of the washing machine body 7 (above the washing tub 2 in the embodiment of FIG. 5). The atomizer 3 and the washing tub 2 are communicated. The discharge path 16 meanders in the vertical direction, and a drainage small hole 23a constituting the drainage means 23 is provided at the bottom of the valley 16a, and one end of a drainage pipe 23b is connected to the drainage small hole 23a. When water accumulates in the valley 16a portion of the discharge path 16 meandering up and down, the water is drained into the washing tub 2 or the drainage channel 12 through the drain pipe 23b.

本実施形態においては、洗浄運転やすすぎ運転において洗濯槽2内で洗浄水が飛散して放出経路16の端部開口から放出経路16内に浸入しても、上下方向に蛇行した放出経路16内の谷16a部分に溜まってそれ以上浸入せず、上下に蛇行した放出経路16の奥に位置する静電霧化装置3に水が浸入することがないようになっている。放出経路16内の谷16aに溜まった洗浄水は排水管23bを介して洗濯槽2内又は排水路12に排水される。したがって、静電霧化装置3を運転して帯電微粒子水を生成して放出経路16を通して洗濯槽2内に帯電微粒子水を放出する除菌・脱臭運転の際は、放出経路16内の谷16aに水が溜まっておらず、スムーズに放出経路16を通して洗濯槽2内に帯電微粒子水を放出することができる。   In this embodiment, even if washing water scatters in the washing tub 2 and enters the discharge path 16 from the end opening of the discharge path 16 in the washing operation and the rinsing operation, the inside of the discharge path 16 meandering vertically. Thus, water does not enter the electrostatic atomizer 3 located in the back of the discharge path 16 meandering up and down and accumulated in the valleys 16a of the water. The washing water accumulated in the valley 16a in the discharge path 16 is drained into the washing tub 2 or the drainage channel 12 through the drain pipe 23b. Therefore, during the sterilization / deodorization operation in which the electrostatic atomizer 3 is operated to generate charged fine particle water and discharge the charged fine particle water into the washing tub 2 through the discharge path 16, the valley 16 a in the discharge path 16. Thus, the charged fine particle water can be smoothly discharged into the washing tub 2 through the discharge path 16.

本実施形態では放出経路16を上下方向に蛇行するものとすることで、静電霧化装置3に洗浄水が浸入しないようにしたものであり、他の構成、作用は前述の実施形態と同様であるので、説明は省略する。   In the present embodiment, the discharge path 16 meanders in the vertical direction so that the washing water does not enter the electrostatic atomizer 3, and other configurations and operations are the same as those in the above-described embodiment. Therefore, explanation is omitted.

また、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、洗濯機1における洗濯物の洗濯処理のための一連の洗濯運転が、洗濯物の洗浄運転、洗濯物のすすぎ運転、洗濯物の脱水運転、洗濯物の乾燥運転、静電霧化装置3を運転して帯電微粒子水を洗濯槽2内に放出することによる洗濯物の除菌・脱臭を行う除菌・脱臭運転を順番に行うものであってもよい。   Further, the example of the washing machine 1 referred to as a washing / drying machine having a washing function and a drying function has been described as the washing machine 1. However, in the washing machine having only the washing function as the washing machine 1, washing in the washing machine 1 is performed. A series of washing operations for washing the laundry is performed by washing the laundry, rinsing the laundry, dehydrating the laundry, drying the laundry, and driving the electrostatic atomizer 3. May be sequentially performed for disinfecting and deodorizing the laundry by discharging the product into the washing tub 2.

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.
