上記構成において、洗濯から乾燥行程の基本的な動作を説明する。 In the above configuration, the basic operation from washing to drying will be described.

洗濯行程では、外蓋４９を開け、中蓋２１を開けて、内槽４に衣類と洗剤を投入し、運転を開始すると所定の水位まで給水した後、モータ８を駆動する。このとき、伝達機構部のクラッチ９によりモータ８の動力を、洗濯軸を介してパルセータ６に伝達し、パルセータ６が回転することで、衣類がパルセータ６の撹拌用突出部１１に引っかかり、中心部へ引き込まれる。内槽４の中心下層部の衣類は、引き込まれた衣類により、内槽４の上層部へ押し上げられる。このようにして内槽４内の衣類を撹拌して、衣類同士、または内槽４の内壁やパルセータ６との接触により作用する機械力と、水流力により行われる。 In the washing process, the outer lid 49 is opened, the inner lid 21 is opened, clothes and detergent are put into the inner tub 4, and when the operation is started, water is supplied to a predetermined water level, and then the motor 8 is driven. At this time, the power of the motor 8 is transmitted to the pulsator 6 through the washing shaft by the clutch 9 of the transmission mechanism, and the pulsator 6 rotates, so that the clothes are caught by the agitation protrusion 11 of the pulsator 6 and the center part. Drawn into. The clothing at the center lower layer portion of the inner tub 4 is pushed up to the upper layer portion of the inner tub 4 by the drawn-in clothing. In this way, the clothes in the inner tub 4 are agitated, and the mechanical force acting by the contact between the clothes or the inner wall of the inner tub 4 or the pulsator 6 and the water flow force are used.

脱水行程では、洗濯終了後、排水弁２２を開いて内槽４内の水を排水ホース２４より排水した後、伝達機構部のクラッチ９を脱水側に切り換えて、モータ８の動力を、脱水軸を介し内槽４に伝達して回転させ、衣類に遠心力を与えることにより、水分を衣類から分離することで行う。 In the dehydration process, after the washing is completed, the drain valve 22 is opened and the water in the inner tub 4 is drained from the drain hose 24, and then the clutch 9 of the transmission mechanism is switched to the dehydration side to This is performed by separating the moisture from the garment by transmitting it to the inner tub 4 and rotating it and applying centrifugal force to the garment.

乾燥行程では、クラッチ９を洗濯側に切り換えてモータ８を駆動してパルセータ６に伝達し、パルセータ６を急速に正転、反転することで、脱水後に内槽４の内壁に張り付いた衣類を引き剥がす。つぎに、パルセータ６を正転、反転させて撹拌用突出部１１で衣類を引っかけて撹拌しながら、乾燥用ファン１５などからなる送風手段６５、ヒータ１６により温風を空気噴出口２０に送る。空気噴出口２０より内槽４に吹き込まれた温風は、衣類から水分を蒸発させた後、内槽４から外槽３の内側へ出た後、排水経路口１４より接続ダクト１３を通過して、熱交換ダクト１２へ至る。 In the drying process, the clutch 9 is switched to the washing side, the motor 8 is driven and transmitted to the pulsator 6, and the pulsator 6 is rapidly rotated forward and reverse to reverse the clothes attached to the inner wall of the inner tub 4 after dehydration. Peel off. Next, while the pulsator 6 is rotated forward and reversely and clothes are caught by the stirring protrusion 11 and stirred, warm air is sent to the air outlet 20 by the blowing means 65 and the heater 16 including the drying fan 15 and the like. The warm air blown into the inner tub 4 from the air outlet 20 evaporates moisture from the clothing, then exits from the inner tub 4 to the inside of the outer tub 3, and then passes through the connection duct 13 from the drainage passage port 14. To the heat exchange duct 12.

衣類の水分を奪って湿気を含んだ温風が、外槽３の内壁や熱交換ダクト１２内を通過しているとき、筐体１の側面に設置した冷却送風機２５による外部空気の流入で、外槽３や熱交換ダクト１２の外壁は冷却されることになり、その内部では、水分の結露が起こり、湿った温風は除湿されて、循環風受け室４５へ入り、フィルター４６を通過してから乾燥用ファン１５へ戻る。この循環路で温風を循環させることにより、内槽４内の衣類を乾燥させることができる。 When hot air containing moisture from the clothes deprived of moisture passes through the inner wall of the outer tub 3 or the heat exchange duct 12, the inflow of external air by the cooling blower 25 installed on the side surface of the housing 1, The outer walls of the outer tub 3 and the heat exchange duct 12 are cooled, moisture condensation occurs inside, and the moist hot air is dehumidified and enters the circulating air receiving chamber 45 and passes through the filter 46. After that, the process returns to the drying fan 15. By circulating the warm air in this circulation path, the clothes in the inner tub 4 can be dried.

また、上記の乾燥用ファン１５駆動時に静電霧化発生装置５５（図４にて後述）を動作させると、帯電微粒子水が空気循環経路１７の出口側の空気噴出口２０より、内槽４内部の衣類に放出される。 Further, when the electrostatic atomization generator 55 (described later with reference to FIG. 4) is operated when the drying fan 15 is driven, the charged fine particle water flows from the air outlet 20 on the outlet side of the air circulation path 17 into the inner tank 4. Released into internal clothing.

図４は、本発明の実施の形態１における洗濯乾燥機の静電霧化発生ユニット部の要部断面図である。 FIG. 4 is a cross-sectional view of a main part of the electrostatic atomization generating unit portion of the washing / drying machine according to Embodiment 1 of the present invention.

図４において、支持部材５０の下方から取り付け、固定されている静電霧化発生ユニット５３には、静電霧化取り付け板６３内方に、取り付け板Ａ５７に固定された静電霧化発生装置５５、および取り付け板Ｂ５８に固定された制御回路である静電霧化駆動手段５６が設けられている。 In FIG. 4, the electrostatic atomization generating unit 53 attached and fixed from below the support member 50 has an electrostatic atomization generator fixed to the attachment plate A 57 inside the electrostatic atomization attachment plate 63. 55 and electrostatic atomization driving means 56 which is a control circuit fixed to the attachment plate B58.

なお、図示していないが、静電霧化発生装置５５と制御回路である静電霧化駆動手段５６とはリード線や接続コネクターで電気的な接続がなされている。 Although not shown, the electrostatic atomization generator 55 and the electrostatic atomization drive means 56 that is a control circuit are electrically connected by a lead wire or a connection connector.

取り付け板Ａ５７には、静電霧化発生装置５５の下部に空気流入口５９が形成され、静電霧化取り付け板６３の側壁には、静電霧化発生装置５５よりも低い位置に帯電微粒子水放出口６０が形成され、帯電微粒子水放出口６０は、送風手段６５の構成部材の循環風受け室４５と連通している。 An air inlet 59 is formed in the lower part of the electrostatic atomization generating device 55 in the mounting plate A57, and the charged fine particles are located on the side wall of the electrostatic atomizing mounting plate 63 at a position lower than the electrostatic atomization generating device 55. A water discharge port 60 is formed, and the charged fine particle water discharge port 60 communicates with the circulating wind receiving chamber 45 of the constituent member of the blowing means 65.

また、静電霧化取り付け板６３の帯電微粒子水放出口６０と静電霧化発生装置５５との間には、遮蔽壁６１が、取り付け板Ａ５７の底面と間隙をもって、かつ、下方に垂下したリブ形状の先端が、前記帯電微粒子水放出口６０の下端より下方になるよう形成され、帯電微粒子水放出口６０と静電霧化発生装置５５とを防水可能に遮蔽している。 Further, between the charged fine particle water discharge port 60 of the electrostatic atomization mounting plate 63 and the electrostatic atomization generator 55, the shielding wall 61 hangs downward with a gap from the bottom surface of the mounting plate A57. The rib-shaped tip is formed so as to be lower than the lower end of the charged fine particle water discharge port 60 and shields the charged fine particle water discharge port 60 and the electrostatic atomization generator 55 in a waterproof manner.

上記の静電霧化発生ユニット５３の構成にて、帯電微粒子水を放出する行程における動作を説明する。なお、帯電微粒子水を放出する除菌・脱臭運転コース（ナノイーコース）は、乾燥行程と同様に制御される行程であるが、ヒータ１６のみ動作しない。 The operation in the process of discharging the charged fine particle water with the configuration of the electrostatic atomization generating unit 53 will be described. Note that the sterilization / deodorization operation course (nanoecourse) that discharges charged fine particle water is a process that is controlled in the same manner as the drying process, but only the heater 16 does not operate.

制御手段３３からの指示で静電霧化駆動手段５６が駆動すると、静電霧化発生装置５５が動作し、空気流入口５９から流入した空気が、静電霧化発生装置５５の放電電極（図示せず）に、結露水として供給され、そこへ高電圧が印加されて、マイナスに帯電したナノメータサイズの帯電微粒子水が大量に生成される。 When the electrostatic atomization driving means 56 is driven by an instruction from the control means 33, the electrostatic atomization generating device 55 is operated, and the air flowing in from the air inlet 59 is discharged to the discharge electrode ( (Not shown) is supplied as dew condensation water, and a high voltage is applied thereto to produce a large amount of negatively charged nanometer-size charged fine particle water.

帯電微粒子水を放出する除菌・脱臭運転コース（ここではナノイーコースと呼ぶ）は、ヒータ１６には通電されないが、乾燥行程と同様の行程であるため、内槽４内の衣類を通過した風が、熱交換ダクト１２内を通過し、循環風受け室４５へ入り、フィルター４６を通過してから乾燥用ファン１５へ行き、上部蛇腹状ホース１８を経由して空気噴出口２０より内槽４に戻されるという大きな循環風の流れがある。 The sterilization / deodorization operation course (hereinafter referred to as “nanoe course”) that discharges charged fine particle water is not energized to the heater 16 but is a process similar to the drying process. Passes through the heat exchange duct 12, enters the circulation wind receiving chamber 45, passes through the filter 46, goes to the drying fan 15, and passes through the upper bellows-like hose 18 from the air outlet 20 to the inner tank 4. There is a large circulating wind flow that is returned to.

このため、循環風受け室４５と帯電微粒子水放出口６０により連通している、静電霧化取り付け板６３と取り付け板Ａ５７で形成される静電霧化室６４は、循環風が流れる循環経路に対して容積が小さいため、負圧状態となる。これにより、循環風が流れている時に、生成された帯電微粒子水は、帯電微粒子水放出口６０から循環風受け室４５内に吸い込まれ、吸い込まれた帯電微粒子水は、循環風の流れに乗って内槽４内に放出され、攪拌されている衣類の繊維の内部に奥深く浸透して、除菌、脱臭が行われる。 For this reason, the electrostatic atomization chamber 64 formed by the electrostatic atomization attachment plate 63 and the attachment plate A57, which is communicated by the circulation air receiving chamber 45 and the charged fine particle water discharge port 60, is a circulation path through which the circulation air flows. In contrast, since the volume is small, a negative pressure state occurs. Thus, when the circulating wind is flowing, the generated charged fine particle water is sucked into the circulating wind receiving chamber 45 from the charged fine particle water discharge port 60, and the sucked charged fine particle water rides on the flow of the circulating wind. Then, it is discharged into the inner tub 4 and penetrates deeply into the fiber of the clothes being stirred, so that sterilization and deodorization are performed.

以上のように、本実施の形態においては、静電霧化発生ユニットは、前記帯電微粒子水を、前記送風手段に設けた空気噴出口より前記内槽に、上方から放出したことにより、パルセータの回転による遠心力で上方へと舞い上がった衣類に、帯電微粒子水が効果的に付着浸透し、除菌、脱臭効果をより高めるものである。 As described above, in the present embodiment, the electrostatic atomization generating unit discharges the charged fine particle water from above from the air outlet provided in the blowing means to the inner tank, Charged fine particle water effectively adheres and penetrates into clothing that has swung upward due to centrifugal force caused by rotation, thereby further enhancing the sterilization and deodorization effects.

また、静電霧化発生装置が、静電霧化取り付け板内方で送風手段の負圧領域に配置し構成されることにより、静電霧化発生ユニットへの水分を含む循環風の流れ込みを防ぐと共に、使用者によっては、洗濯終了後に、洗濯機上面、内面に水をかけて掃除するという人もいるが、フィルターを外して、循環風受け室に水をかけた場合でも、水が入る可能性のある帯電微粒子水放出口は、静電霧化発生装置より低い位置にあり、また、遮蔽壁による防水効果で、静電霧化発生装置に水がかかることはなく、絶縁劣化を起こす危険性が無く安全性に優れている。 In addition, the electrostatic atomization generator is arranged and configured in the negative pressure region of the blowing means inside the electrostatic atomization mounting plate, thereby allowing the circulation of the circulating wind containing moisture to the electrostatic atomization generation unit. In addition to preventing this, some users may clean the top and inner surfaces of the washing machine with water after washing, but even if the filter is removed and the circulation wind chamber is filled with water, water will enter. There is a possibility that the charged fine particle water outlet is located lower than the electrostatic atomization generator, and the waterproof effect of the shielding wall prevents water from splashing on the electrostatic atomizer and causes insulation deterioration. There is no danger and it is excellent in safety.

さらに送風手段の負圧領域に配置することで、専用の送風ファンやホースなどが不要となり、生産性やコストの面でも優れた効果を得ることができる。 Furthermore, by disposing in the negative pressure region of the blower means, a dedicated blower fan, a hose or the like is unnecessary, and an excellent effect in terms of productivity and cost can be obtained.

以上のように、本発明にかかる洗濯乾燥機は、帯電微粒子水を衣類の繊維の内部に奥深く、確実に浸透させて除菌、脱臭を行ない、かつ、安価で製造できるとともに、静電霧化発生装置の破損や劣化を防止することができるので、洗濯機や乾燥機等の用途にも適用できる。 As described above, the washing / drying machine according to the present invention can be manufactured at a low cost by performing the sterilization and deodorization by deeply and reliably infiltrating the charged fine particle water into the fiber of the clothing, and electrostatic atomization. Since the generator can be prevented from being damaged or deteriorated, it can be applied to uses such as washing machines and dryers.
