In FIG. 10, the washing and drying machine 1 has a casing 2, a door 12 for attaching and removing clothes 6 is attached to the center of the casing 2, and a rotating drum 3 is accommodated therein. A predetermined portion of the rotating drum 3 is provided with a beater 5 for lifting and dropping the clothing 6 along with the rotation of the rotating drum 3, and a punching hole 4 through which washing water 7 and circulating air 9 for drying enter and exit. . The shaft 11 of the rotary drum 3 receives power for rotation from a drive motor (not shown).

また、ケーシング２内の回転ドラム３の背面は、空気入口２４及び空気出口２３を除き隔壁２２によって仕切られ、循環エア９が通るダクト１０、及び１３が形成されている。前記隔壁２２の前面下部は洗濯槽１４を構成し、同洗濯槽１４の部分に回転ドラム３の下部が臨んでいる。 Further, the rear surface of the rotating drum 3 in the casing 2 is partitioned by a partition wall 22 except for the air inlet 24 and the air outlet 23, and ducts 10 and 13 through which the circulating air 9 passes are formed. The lower part of the front surface of the partition wall 22 constitutes a washing tub 14, and the lower part of the rotating drum 3 faces the portion of the washing tub 14.

前記各エアダクト１０、１３には圧縮機１９、凝縮器（コンデンサ）１８、ファン１７、膨脹弁２０、蒸発器（エバポレータ）１５等が内蔵されており、いわゆるヒートポンプサイクルが形成されている。また、コンデンサ１８の一部はケーシング外背面に延長され、加熱器１６を形成している。２１はドレン排水用配管、８は洗濯排水用配管である。 Each of the air ducts 10 and 13 incorporates a compressor 19, a condenser (condenser) 18, a fan 17, an expansion valve 20, an evaporator (evaporator) 15 and the like, and a so-called heat pump cycle is formed. Further, a part of the capacitor 18 is extended to the outer back surface of the casing to form a heater 16. 21 is a drain drain pipe, and 8 is a washing drain pipe.

次に、各工程と作用について説明する。洗濯、すすぎ工程は、ドア１２をあけて衣類６及び適量の洗剤を投入し、ドア１２を閉め、以下の工程を実行する。水供給バルブ（図示せず）から洗濯槽１４に水位Ａの位置まで規定量の水７が供給される。回転ドラム３がプログラムされた回転数で連続または間欠的に回転し、洗浄が行なわれる。この間、衣類６はビータ５によって持ち上げられ落下する。洗濯終了後は洗濯槽１４の洗濯排水用配管８から機外に排水される。続いて、すすぎ工程が同様の工程で実行される。すすぎ水も洗濯排水として洗濯排水用配管８から機外に排水される。 Next, each process and operation will be described. In the washing and rinsing process, the door 12 is opened, the garment 6 and an appropriate amount of detergent are added, the door 12 is closed, and the following processes are executed. A prescribed amount of water 7 is supplied from a water supply valve (not shown) to the washing tub 14 up to the position of the water level A. The rotating drum 3 rotates continuously or intermittently at the programmed number of rotations to perform cleaning. During this time, the garment 6 is lifted and dropped by the beater 5. After washing is completed, the water is drained from the washing drain pipe 8 of the washing tub 14 to the outside of the machine. Subsequently, the rinsing process is performed in the same process. Rinsing water is also drained out of the machine from the washing drain pipe 8 as washing drain.

In the washing process from washing, rinsing, and dehydration, when water is stored, the state of the valve 61 of the drain valve 60 is the d side in FIG. 3, the washing drain path 47 side is closed, and the condensation drain path 49 side is open. Water is supplied to the washing tub 26 from a water supply valve (not shown), and is stored up to the position of the water level D in FIG. The rotating drum 26 rotates continuously or intermittently at a programmed number of rotations, and rinsing and rinsing are performed. During this time, the clothes 31 are lifted and dropped by the rotation of the rotating drum 26. When draining, the valve 61 of the drain valve 60 is set to the e side in FIG. The laundry drainage channel 47 side is open and the condensation drainage channel 49 side is closed. The water in the washing tub 14 passes through the washing drain channel 47 and the drain valve 60 and is drained from the drain pipe 50 to the outside of the machine.

乾燥工程では、圧縮機３５が停止している間は排水弁６０の弁６１を図３のｄ側にして洗濯排水路４７側が閉で結露排水路４９側が開とする。圧縮機３５、送風手段４３及び回転ドラム２８が運転されると、排水弁６０の弁６１を図３のｅ側にして洗濯排水路４７側が開で結露排水路４９側が閉とする。送風手段４３の運転によって、乾燥用空気が洗濯槽２６とダクト４４、フレキシブルホース４２、風路４１、フレキシブルホース４２の内部を循環する。衣類３１は、あらかじめ設定された回転数で連続又は間欠的に行われる回転ドラム２８の回転によって撹拌される。 In the drying process, while the compressor 35 is stopped, the valve 61 of the drainage valve 60 is set to the d side in FIG. 3 so that the washing drainage channel 47 side is closed and the condensation drainage channel 49 side is open. When the compressor 35, the blowing means 43, and the rotary drum 28 are operated, the valve 61 of the drain valve 60 is set to the e side in FIG. 3 so that the washing drain path 47 side is open and the condensation drain path 49 side is closed. By the operation of the blowing means 43, the drying air circulates inside the washing tub 26 and the duct 44, the flexible hose 42, the air passage 41, and the flexible hose 42. The clothing 31 is agitated by the rotation of the rotating drum 28 continuously or intermittently performed at a preset number of rotations.

圧縮機３５の運転によって、管路３９内を冷媒が循環して、加熱器３６で高温高圧の冷媒の熱を加熱して循環する乾燥用空気を加熱する。加熱された乾燥用空気は図２の矢印Ｃのように、洗濯槽２６内に送り込まれ、回転ドラム２８底面部の開口部４６を通過して衣類３１に当たり、衣類３１から水分を奪って、多湿の空気となって回転ドラム２８の側壁の孔４５を通過して、洗濯槽２６の開口部５６を通過してダクト４４へと送られる。ダクト４４を通過した乾燥用空気は、矢印Ｂに示すように、フレキシブルホース４２を通過して風路４１に設けた除湿手段４０としての冷却器３８で、冷却除湿される。除湿された乾燥用空気は再び送風手段によって加熱器３６に送られて加熱される。 By the operation of the compressor 35, the refrigerant circulates in the pipeline 39, and the drying air heated by the heater 36 is heated by the heat of the high-temperature and high-pressure refrigerant. The heated drying air is sent into the washing tub 26 as shown by an arrow C in FIG. 2, passes through the opening 46 in the bottom of the rotating drum 28 and hits the clothing 31, deprives the clothing 31 of moisture, and is humid. The air passes through the hole 45 on the side wall of the rotary drum 28, passes through the opening 56 of the washing tub 26, and is sent to the duct 44. The drying air that has passed through the duct 44 passes through the flexible hose 42 and is cooled and dehumidified by the cooler 38 as the dehumidifying means 40 provided in the air passage 41 as indicated by an arrow B. The dehumidified drying air is sent again to the heater 36 by the blowing means and heated.

ここで、インバータを用いて圧縮機３５を駆動すると、ＰＷＭに同期して圧縮機３５内部の巻き線とケースの間に冷媒の静電容量により高周波の漏れ電流が流れる。除湿手段４０は導電体で構成されているため、除湿手段４０内部では漏れ電流が流れることとなる。一方、結露水は導電体であるため、除湿手段４０に接している結露水には漏れ電流が流れることとなり、圧縮機３５運転中に結露水が線状に連なった状態で外部に排出されると、冷却水を伝って外部に漏れ電流が流れることとなるが、圧縮機３５運転中は排水弁６０により結露排水路４９を閉じることにより、外部に漏れ電流が流れることを防ぐことができる。 Here, when the compressor 35 is driven using an inverter, a high-frequency leakage current flows between the winding inside the compressor 35 and the case in synchronization with PWM due to the electrostatic capacity of the refrigerant. Since the dehumidifying means 40 is composed of a conductor, a leakage current flows inside the dehumidifying means 40. On the other hand, since the dew condensation water is a conductor, a leakage current flows through the dew condensation water in contact with the dehumidifying means 40, and the dew condensation water is discharged to the outside in a linear state during the operation of the compressor 35. Then, a leakage current flows to the outside through the cooling water, but it is possible to prevent the leakage current from flowing to the outside by closing the condensation drainage channel 49 by the drain valve 60 during the operation of the compressor 35.

以上のように、本実施の形態においては、圧縮機３５の運転中は排水弁６０により結露排水路４９を閉じることにより、漏れ電流が流れている間は結露水が外部に排出されることを防ぐこととなり、漏れ電流が外部に流れることを防ぐことができる。 As described above, in the present embodiment, during the operation of the compressor 35, the condensed drainage channel 49 is closed by the drain valve 60 so that the condensed water is discharged to the outside while the leakage current is flowing. This prevents the leakage current from flowing to the outside.

また、圧縮機３５の運転開始前に排水弁６０により結露排水路４９を開いてあらかじめ結露水を排出しておくことにより、排水タンク４８の容量を有効に利用することができる。 Moreover, the capacity | capacitance of the drainage tank 48 can be effectively utilized by opening the condensation drainage channel 49 by the drainage valve 60 and discharging condensed water beforehand before the compressor 35 starts operation.

また、圧縮機３５の運転終了後に排水弁６０により結露排水路４９を開いて内部の結露水を排出しておくことにより、運転後長期間結露水を排水タンク４８内に貯留させておくことが無く、衛生面でも有利となる。 Further, after the operation of the compressor 35 is completed, the condensation drainage channel 49 is opened by the drain valve 60 to discharge the condensed water inside, so that the condensed water can be stored in the drainage tank 48 for a long time after the operation. There is no advantage in hygiene.

また、結露排水路４９は一部の内径が他の部分より小さくなっているため結露水が線状に連なった状態で外部に排出されることがなく、何らかの原因で圧縮機３５の運転中に結露水が排出されても漏れ電流が外部に流れることを防ぐことができる。 In addition, since the dew condensation drainage channel 49 has a smaller inner diameter than the other part, the dew condensation water is not discharged to the outside in a linear state, and the compressor 35 is in operation for some reason. Even if condensed water is discharged, leakage current can be prevented from flowing to the outside.
