本実施の形態における洗濯乾燥機は、洗濯行程のみを行う洗濯コース、乾燥行程のみを行う乾燥コース、洗濯行程から乾燥行程まで連続で行う洗濯乾燥コース、除菌・消臭行程を行うナノイーコースの4種類の運転コースを使用者が選択できるようになっている。   The washing / drying machine according to the present embodiment includes a washing course that performs only a washing process, a drying course that performs only a drying process, a washing and drying course that is continuously performed from the washing process to the drying process, and a nano e-course that performs a sterilization / deodorization process. The user can select four kinds of driving courses.

まず、洗濯行程の動作について、順に説明する。扉35を開いて洗濯槽内に洗濯物及び洗剤を投入して、筺体100の前面上部に設けられた操作パネル40での入力操作により、制御部41などによる制御を通じて運転が開始すると、水槽2内には給水管路(図示せず)から所定量の給水がなされ、駆動モータ3によりドラム1が回転駆動されて洗い行程が開始される。   First, the operation of the washing process will be described in order. When the door 35 is opened, laundry and detergent are put into the washing tub, and the operation is started through the control by the control unit 41 or the like by the input operation on the operation panel 40 provided on the front upper portion of the housing 100, the water tub 2 A predetermined amount of water is supplied from a water supply pipe (not shown), and the drum 1 is rotationally driven by the drive motor 3 to start the washing process.

ドラム1の回転により、ドラム1内に収容された洗濯物は、ドラム1の内周壁に設けられた撹拌突起によって回転方向に持ち上げられ、持ち上げられた適当な高さ位置から落下する撹拌動作が繰り返されるので、洗濯物には叩き洗いの作用が及んで洗浄がなされる。   By the rotation of the drum 1, the laundry accommodated in the drum 1 is lifted in the rotation direction by the stirring protrusion provided on the inner peripheral wall of the drum 1, and the stirring operation of dropping from the lifted appropriate height position is repeated. As a result, the laundry is subjected to tapping and washing.

所要の洗濯時間の後、汚れた洗濯液は、排水弁27を開いて排水管40から排出され、そのまま排水弁27を開いた状態で、ドラム1を高速回転させる中間脱水動作により、洗濯物に含まれた洗濯液をしぼり出し、その後、水槽2内に給水管路から給水して、すすぎ行程が実施される。このすすぎ行程においても、ドラム1内に収容された洗濯物は、ドラム1の撹拌突起により回転方向に持ち上げられて落下する撹拌動作が繰り返されて、すすぎが実施される。すすぎ行程が終わると排水され、ドラム1を高速回転させる脱水行程が始まり、洗濯物の水分を飛ばして洗濯行程を終了する。   After the required washing time, the dirty washing liquid is discharged from the drain pipe 40 by opening the drain valve 27, and is left in the laundry by an intermediate dehydration operation in which the drum 1 is rotated at a high speed with the drain valve 27 opened. The contained washing liquid is squeezed out, and then the water is supplied into the water tank 2 from the water supply pipe, and the rinsing process is performed. Also in this rinsing process, the laundry stored in the drum 1 is rinsed by repeating the stirring operation in which the laundry is lifted by the stirring protrusion of the drum 1 and dropped. When the rinsing process is finished, the water is drained, and a dehydration process for rotating the drum 1 at high speed is started, and the washing process is completed by removing moisture from the laundry.

次に乾燥行程の動作について順に説明する。扉35を開いてドラム1内に、脱水された
洗濯物を投入して、筺体100の前面上部に設けられた操作パネル40での入力操作により、制御部41などによる制御を通じて運転が開始すると、送風部4の送風用ファンモータ4bと送風用ファン4aの動作により、水槽2内の空気を吸引して排出口5を経てヒートポンプ装置50に通し、ヒートポンプ装置50により除湿及び加熱した空気にして、ドラム1の後方に開口した、第一の送風経路9の第一吹出口8から、水槽2およびドラム1内に循環送風する。
Next, operation | movement of a drying process is demonstrated in order. When the door 35 is opened, the dehydrated laundry is put into the drum 1, and the operation is started through the control by the control unit 41 or the like by the input operation on the operation panel 40 provided on the front upper portion of the housing 100, By the operation of the blower fan motor 4b and the blower fan 4a of the blower unit 4, the air in the water tank 2 is sucked and passed through the discharge port 5 to the heat pump device 50, and is dehumidified and heated by the heat pump device 50, The air is circulated through the water tank 2 and the drum 1 from the first air outlet 8 of the first air passage 9 that is opened behind the drum 1.

この循環を所定時間繰り返した後、風路切替手段12により、循環風路を第二の送風経路11に切り替えて、ドラム1の前方上部に開口した第二吹出口10から循環空気を吹き出して、乾燥行程を継続させ、洗濯物を乾燥させる。なお、乾燥行程においては、乾燥させる対象物に応じて、ドラム1を回転動作させる回転モード、およびドラム1を回転させない静止モードを選択することができる。   After repeating this circulation for a predetermined time, the air passage switching means 12 switches the circulation air passage to the second air passage 11 and blows out the circulating air from the second air outlet 10 opened at the upper front of the drum 1. Continue the drying process to dry the laundry. In the drying process, a rotation mode in which the drum 1 is rotated and a stationary mode in which the drum 1 is not rotated can be selected according to an object to be dried.

洗濯から乾燥まで連続で行う洗濯乾燥コースは、前記洗濯行程後に、前記乾燥行程が順次実行されるよう制御されたものである。   The washing / drying course continuously performed from washing to drying is controlled so that the drying process is sequentially executed after the washing process.

図2は、除菌・消臭行程を行なうナノイーコースの動作シーケンスを示すものである。   FIG. 2 shows an operation sequence of nanoecourse which performs the sterilization / deodorization process.

図2において、扉35を開いてドラム1内に処理対象物を投入して、筺体100の前面上部に設けられた操作パネル7での操作でナノイーコースを選択して、運転を開始させると、送風部4と静電霧化発生装置42を動作させ、静電霧化発生装置42から発生した帯電微粒子水を、送風部4の送風用ファンモータ4bと送風用ファン4aの回転により、第一の送風経路9の第一吹出口8から、水槽2およびドラム1内に送りながら処理対象物を除菌・消臭する行程を開始する。   In FIG. 2, when the door 35 is opened, a processing object is put into the drum 1, nanoecourse is selected by an operation on the operation panel 7 provided at the upper front of the housing 100, and operation is started. The blower unit 4 and the electrostatic atomization generator 42 are operated, and the charged fine particle water generated from the electrostatic atomization generator 42 is first rotated by the rotation of the blower fan motor 4b and the blower fan 4a of the blower unit 4. The process of disinfecting and deodorizing the processing object is started while being fed into the water tank 2 and the drum 1 from the first air outlet 8 of the air flow path 9.

運転開始から20分間の第一の送風経路9からの送風時は、送風用ファン4aの回転数を略3000rpmとし、それ以降は風路切替手段12により、循環風路を第二の送風経路11に切り替えて、第二吹出口10から帯電微粒子水を含んだ循環空気をドラム1内に吹き出す。この時は、送風用ファン4aの回転数を略5000rpmとしている。これは、各風路の風路圧損が異なるため、送風用ファン4aの回転数を同じにした場合、ドラム1に送風される風量が異なってしまうため、ドラム1に送風される単位時間当たりの風量をほぼ同じにする目的で送風ファン回転数を変化させたものである。なお、送風用ファンモータ4aの回転数は、各風路の風路圧損に合わせて設定することができ、上記の回転数に限定されるものではない。   At the time of air blowing from the first air passage 9 for 20 minutes from the start of operation, the rotational speed of the air blowing fan 4a is set to about 3000 rpm, and thereafter the air passage switching means 12 changes the circulation air passage to the second air passage 11. Then, circulating air containing charged fine particle water is blown out from the second air outlet 10 into the drum 1. At this time, the rotational speed of the blower fan 4a is set to approximately 5000 rpm. This is because the air path pressure loss of each air path is different, and therefore when the rotation speed of the blower fan 4a is the same, the air volume blown to the drum 1 is different, so that the air flow per unit time blown to the drum 1 is different. The rotational speed of the blower fan is changed for the purpose of making the air volume almost the same. In addition, the rotation speed of the fan motor 4a for ventilation can be set according to the air path pressure loss of each air path, and is not limited to said rotation speed.

なお、本実施の形態ではヒートポンプ装置50が取り付けられた構成であり、運転開始からの5分間はヒートポンプ装置50を動作させ、ドラム1内の湿度を下げるよう制御させている。これは、洗濯乾燥機は、通常、残水や密閉度の高さからドラム1内の湿度が90%以上となっているが、静電霧化発生を安定して行うには湿度85%以下であることが望ましいため、運転開始直後の所定時間はヒートポンプ装置50を動作させ、ドラム1内の湿度を低下させるための除湿を行うためである。   In this embodiment, the heat pump device 50 is attached, and the heat pump device 50 is operated for 5 minutes from the start of operation to control the humidity in the drum 1 to be lowered. This is because the humidity in the drum 1 is usually 90% or higher due to the residual water and the high degree of sealing, but the humidity is 85% or lower for stable electrostatic atomization. Therefore, the predetermined time immediately after the start of operation is for operating the heat pump device 50 to perform dehumidification to reduce the humidity in the drum 1.

ただし、ヒートポンプ装置50動作時は一気にドラム1内の湿度が低下し、と静電霧化発生装置42による静電霧化発生が不安定になる恐れがあるため、ヒートポンプ装置50動作時は、静電霧化発生装置42を停止するよう制御させる。   However, when the heat pump device 50 is operating, the humidity in the drum 1 may drop at a stroke, and the electrostatic atomization generation by the electrostatic atomization generating device 42 may become unstable. The electroatomization generator 42 is controlled to stop.

本実施の形態では除菌・消臭行程は30分間で制御されており、これによりナノイーコースの運転時間は、基本的に除湿行程5分、除菌・消臭行程30分を合わせた35分となっている。しかし、前記ナノイーコースの運転時間は、これに限定されるものではなく、より短時間なスピーディーコースや、より長時間な念入りコースを設定しても良い。   In the present embodiment, the sterilization / deodorization process is controlled in 30 minutes, and the operation time of Nanoecourse is basically 35 minutes including the dehumidification process of 5 minutes and the sterilization / deodorization process of 30 minutes. It has become. However, the operation time of the nano e course is not limited to this, and a shorter time course or a longer time course may be set.

本実施の形態では、図3に示すように処理対象物の量と設定されるべき運転時間の関係を使用者がわかるように表示し、使用者がその量にあった時間を操作パネル40により選べるようになっている。このとき、各時間において、帯電微粒子水が通過する送風経路は第一の送風経路9と第二の送風経路11の時間がほぼ半分となるように制御される。   In the present embodiment, as shown in FIG. 3, the relationship between the amount of the object to be processed and the operation time to be set is displayed so that the user can understand, and the operation panel 40 indicates the time that the user was in that amount. You can choose. At this time, the air passage through which the charged fine particle water passes is controlled so that the time of the first air passage 9 and the second air passage 11 is almost halved at each time.

また、ナノイーコースは、ドラム1が回転しながら除菌・消臭するモードと、ドラム1が停止したまま除菌・消臭するモードが選択可能であり、処理対象物により使い分ける設定となっている。ドラム1が回転しながら除菌・消臭するモードにおいてのドラム1の動きは、10秒右回転―3秒停止―10秒左回転―3秒停止という比較的短時間に正反転を繰り返すことで、帯電微粒子水を処理対象物に均一に効率よく作用させるよう制御されている。   In addition, the nano e-course can be selected between a mode for sterilization / deodorization while the drum 1 is rotating and a mode for sterilization / deodorization while the drum 1 is stopped. . The movement of the drum 1 in the mode of sterilization and deodorization while the drum 1 is rotating is by repeating forward and reverse in a relatively short time of 10 seconds right rotation-3 seconds stop-10 seconds left rotation-3 seconds stop. The charged fine particle water is controlled to uniformly and efficiently act on the object to be treated.

以上のように、本実施の形態おいては、除菌・消臭行程において、風路切替手段を切り替えることにより、帯電微粒子水を、第一の送風経路の第一吹出口、および第二の送風経路の第二吹出口から、ドラム内に放出するよう構成したことにより、ドラム内に除菌・消臭の対象物が多い場合でも、前後からの帯電微粒子水の放出によって、帯電微粒子水が対象物の全範囲におおよそ万遍なく付着、浸透して、除菌・消臭することができる。   As described above, in the present embodiment, in the sterilization / deodorization process, by switching the air passage switching means, the charged fine particle water is supplied to the first air outlet of the first air passage and the second air outlet. Since it is configured to be discharged into the drum from the second air outlet of the blowing path, even when there are many objects to be sterilized and deodorized in the drum, the charged fine particle water is discharged by the discharge of the charged fine particle water from the front and rear. It is possible to disinfect and deodorize by attaching and penetrating the entire range of the object almost uniformly.

また、第一の送風経路の第一吹出口からの単位時間当たりの風量と、第二の送風経路の第二吹出口からの単位時間当たりの風量を略同等となるよう、送風部の動作を制御することにより、送風経路の圧力損失が異なる場合でも、同量の帯電微粒子水をドラム内に放出することができ、全ての処理対象物を均一に除菌・消臭することができる   In addition, the operation of the air blowing unit is performed so that the air volume per unit time from the first air outlet of the first air passage and the air amount per unit time from the second air outlet of the second air passage are substantially equal. By controlling, even when the pressure loss in the air blowing path is different, the same amount of charged fine particle water can be discharged into the drum, and all the processing objects can be uniformly sterilized and deodorized.

以上のように、本発明にかかる洗濯乾燥機は、ドラムの後部および前部の2つ送風経路から帯電微粒子水を供給することにより、処理対象物が多い場合でも効率よく除菌・消臭することが可能となるので、他の洗濯乾燥機等の用途に適用できる。   As described above, the washing and drying machine according to the present invention efficiently disinfects and deodorizes even when there are many objects to be treated by supplying charged fine particle water from the two air blowing paths at the rear and front of the drum. Therefore, it can be applied to other uses such as a washing dryer.
