The body plate 8a is formed with a large number of through holes 8a1 (only a part of which is shown) for water passage and ventilation. The washing / dehydrating tub 8 is provided with rotary wings 8b on the inner bottom surface.

外槽９は、有底円筒形状を呈し、洗濯兼脱水槽８を同軸上に内包し、その上部に外槽カバー９ａを備えて構成されている。洗濯乾燥機１のユーザは、外蓋３及び外槽カバー９ａの蓋部材９ｃを開くことにより、開口部２ｂから洗濯兼脱水槽８内に洗濯物の出し入れを行うことができる。 The outer tub 9 has a bottomed cylindrical shape, and is configured by coaxially including the washing / dehydrating tub 8 and providing the outer tub cover 9a on the upper portion thereof. The user of the washer / dryer 1 can take in and out the laundry from the opening 2b into the washing / dehydrating tub 8 by opening the lid member 9c of the outer lid 3 and the outer tub cover 9a.

駆動装置１０は、外槽９の底面の外側中央に配置されている。この駆動装置１０は、モータ１０ａとクラッチ機構１０ｂとを有し、駆動装置１０の回転軸１０ｃが外槽９を貫通し、洗濯兼脱水槽８及び回転翼８ｂと結合するように構成されている。クラッチ機構１０ｂは、モータ１０ａの回転動力を洗濯兼脱水槽８及び回転翼８ｂの少なくともいずれかに伝達する機能を有する。モータ１０ａは、その回転を検出するホール素子あるいはフォトインタラプタ等で構成される回転検出装置５と、モータ１０ａに流れる電流を検出するモータ電流検出装置６を備える。 The drive device 10 is arranged in the center of the outside of the bottom surface of the outer tank 9. The drive device 10 has a motor 10a and a clutch mechanism 10b, and is configured such that the rotary shaft 10c of the drive device 10 penetrates the outer tub 9 and is coupled to the washing / dehydrating tub 8 and the rotary blade 8b. .. The clutch mechanism 10b has a function of transmitting the rotational power of the motor 10a to at least one of the washing / dehydrating tank 8 and the rotary blade 8b. The motor 10a includes a rotation detection device 5 composed of a Hall element or a photo interrupter for detecting the rotation thereof, and a motor current detection device 6 for detecting the current flowing through the motor 10a.

投入装置１１は、上面カバー２ａの手前側に備えられる。洗剤や仕上剤の投入は、投入ホース１１ａにより水道水と共に外槽９と洗濯兼脱水槽８の間に行われる。 The loading device 11 is provided on the front side of the upper surface cover 2a. Detergent and finishing agent are charged between the outer tub 9 and the washing / dehydrating tub 8 together with tap water by the charging hose 11a.

給水ユニット７は、上面カバー２ａの奥側に設けられる。この給水ユニット７は、給水ホース接続口４からの水道水を投入装置１１、水冷除湿機構（図示省略）へ給水する。また、給水ユニット７は、給水ホース接続口４からの水道水や吸水ホース接続口からの風呂水を、注水ホース１１ｂを介して、外槽９と洗濯兼脱水槽８の間から外槽９内に注水することができる。また、給水ユニット７は、給水ホース接続口４からの水道水を、洗浄ホース１１ｃを介して洗濯兼脱水槽８の上部に注水することができる。 The water supply unit 7 is provided on the back side of the upper surface cover 2a. The water supply unit 7 supplies tap water from the water supply hose connection port 4 to the input device 11 and the water-cooled dehumidification mechanism (not shown). Further, the water supply unit 7 receives tap water from the water supply hose connection port 4 and bath water from the water absorption hose connection port from between the outer tub 9 and the washing / dehydrating tub 8 to the inside of the outer tub 9 via the water injection hose 11b. Water can be injected into. Further, the water supply unit 7 can inject tap water from the water supply hose connection port 4 into the upper part of the washing / dehydrating tank 8 via the washing hose 11c.

外槽９の底面に設けられた落込部９ｍは、排水弁１４を介して、洗濯水排水路１５と連通するように接続されている。 The drop portion 9 m provided on the bottom surface of the outer tub 9 is connected to the washing water drainage channel 15 via a drain valve 14.

そして、この洗濯水排水路１５には、機外に排水を送り出す図示しない排水ホースが接続されている。 A drain hose (not shown) for sending drainage to the outside of the machine is connected to the washing water drainage channel 15.

ちなみに、排水弁１４を閉弁することにより、外槽９内に洗い水やすすぎ水を貯水可能となる。また、排水弁１４を開弁することにより、外槽９内の水（洗い水、すすぎ水）を、洗濯水排水路１５を介して、洗濯乾燥機１の機外へ排水することができる。 Incidentally, by closing the drain valve 14, it is possible to store wash water and rinse water in the outer tank 9. Further, by opening the drain valve 14, the water (washing water, rinsing water) in the outer tub 9 can be drained to the outside of the washer / dryer 1 via the washing water drainage channel 15.

乾燥ダクト１２は、筐体２の背面内側に縦方向に設置され、ダクト下部は外槽９の落込部９ｍとゴム製の蛇腹管１２ａによって接続されている。乾燥ダクト１２内には、水冷除湿機構（図示省略）が内蔵されており、給水ユニット７は、この水冷除湿機構に冷却水（水道水）を供給する。冷却水は乾燥ダクト１２の壁面を伝わって流下して落込部９ｍに入り、洗濯水排水路１５を通り機外へ排出される。 The drying duct 12 is installed vertically inside the back surface of the housing 2, and the lower part of the duct is connected to the recess 9 m of the outer tank 9 by a rubber bellows tube 12a. A water-cooled dehumidifying mechanism (not shown) is built in the drying duct 12, and the water supply unit 7 supplies cooling water (tap water) to the water-cooled dehumidifying mechanism. The cooling water flows down the wall surface of the drying duct 12, enters the drop portion 9 m, passes through the washing water drainage channel 15, and is discharged to the outside of the machine.

洗濯兼脱水槽８は、胴板８ａの上端縁部に合成樹脂等で形成されたバランスリング（流体バランサともいう）８ｃを備えている。このバランスリング８ｃは、その内部に比重の大きな流体を封入して構成され、洗濯兼脱水槽８の回転時に洗濯物の偏り等によって偏心が生じたときに、バランスリング８ｃ内での流体の移動によって偏心をキャンセルし、回転のバランスを維持する働きを有する。 The washing / dehydrating tub 8 is provided with a balance ring (also referred to as a fluid balancer) 8c formed of a synthetic resin or the like on the upper end edge of the body plate 8a. The balance ring 8c is configured by enclosing a fluid having a large specific gravity inside the balance ring 8c, and when the eccentricity occurs due to the bias of the laundry during the rotation of the washing / dehydrating tub 8, the fluid moves in the balance ring 8c. It has the function of canceling the eccentricity and maintaining the balance of rotation.

外槽カバー９ａは、略半円形状の投入口を有し、外槽９の上端縁部に取り付けられる。なお、投入口には、開閉可能に取り付けられた蓋部材９ｃが設けられている。 The outer tank cover 9a has a substantially semicircular input port and is attached to the upper end edge of the outer tank 9. The input port is provided with a lid member 9c attached so as to be openable and closable.

乾燥ダクト１２の出口は、送風ユニット１３の吸気口と接続され、送風ユニット１３の出口は加熱部であるヒータ１６と接続されている。ヒータ１６の出口は、風路切替部３０に接続されており、風路切替部３０を介し、風が通過する第１送風経路である第１風路（図２参照）、又は、第１送風経路と異なる送風経路である第２風路（図３参照）へ分岐される。第１風路は、図２に示す通り、ゴム製の蛇腹管１７を介して、第１吐出口１８と接続されている。第２風路は、図３に示す通り、ゴム製の蛇腹管２１を介して、第２吐出口２２へと接続されている。つまり、風路切替部３０は、第１風路又は第２風路へ通過させる風の流れる方向を切り替える。 The outlet of the drying duct 12 is connected to the intake port of the blower unit 13, and the outlet of the blower unit 13 is connected to the heater 16 which is a heating unit. The outlet of the heater 16 is connected to the air passage switching unit 30, and is the first air passage (see FIG. 2) or the first air blowing path through which the wind passes through the air passage switching unit 30. It is branched to the second air passage (see FIG. 3), which is a ventilation route different from the route. As shown in FIG. 2, the first air passage is connected to the first discharge port 18 via a rubber bellows tube 17. As shown in FIG. 3, the second air passage is connected to the second discharge port 22 via a rubber bellows pipe 21. That is, the air passage switching unit 30 switches the direction in which the wind passing through the first air passage or the second air passage flows.

つまり、送風ユニット１３が駆動すると、外槽９内の空気が落込部９ｍを介して乾燥ダクト１２に流れ込む。そして、乾燥ダクト１２で水冷除湿された空気は、送風ユニット１３から吐出され、次いでヒータ１６で加熱された後、高温低湿の風となって第１吐出口１８又は第２吐出口２２から洗濯兼脱水槽８内に向けて吹き出される。 That is, when the blower unit 13 is driven, the air in the outer tub 9 flows into the drying duct 12 through the drop portion 9m. Then, the air cooled and dehumidified by water in the drying duct 12 is discharged from the blower unit 13, then heated by the heater 16, and then becomes high-temperature and low-humidity air, which is also used for washing from the first discharge port 18 or the second discharge port 22. It is blown into the dehydration tank 8.

なお、図示していないが、落込部9と排水弁１４の間には、洗濯水の温度や、乾燥運転中に洗濯水排水路１５から機外に排出される空気の温度を検出する温度センサが設けられている。 Although not shown, a temperature sensor is located between the drop portion 9 and the drain valve 14 to detect the temperature of the washing water and the temperature of the air discharged from the washing water drainage channel 15 to the outside of the machine during the drying operation. Is provided.

図１の通り、本体の送風ユニット1３は本体中心より上面後方に配置されている。第１吹出口１８は第２吐出口２２より本体前面側に配置されている。 As shown in FIG. 1, the blower unit 13 of the main body is arranged behind the upper surface from the center of the main body. The first outlet 18 is arranged on the front surface side of the main body from the second outlet 22.

洗濯乾燥コースや乾燥コースが設定されている場合は、乾燥を実行する。この乾燥は排水弁１４を解放したままの状態として、洗濯工程と同様に洗濯兼脱水槽８を静止させた状態で回転翼８ｂを正逆回転させながら、乾燥ダクト１２の後方に設けた送風ユニット１３を運転させることによって、外槽９内の空気を落込部９ｍから乾燥ダクト１２内に吸い出し、この乾燥ダクト１２内を通過するときに該乾燥ダクト１２内で水冷除湿を行い、リントフィルタを(図示省略)通して糸屑を捕集し、ヒータ１６によって加熱した後に第１吐出口１８または、第２吐出口２２から洗濯槽８内に吹きこむことにより行われる。乾燥は温度センサによって温風の温度を監視しながら実行し、温度変化の割合が所定の値になったときに終了する。 If a wash-drying course or drying course is set, perform drying. In this drying, the drain valve 14 is left open, and the air blower unit provided behind the drying duct 12 is provided while rotating the rotary blades 8b in the forward and reverse directions with the washing and dehumidifying tank 8 stationary as in the washing process. By operating 13, the air in the outer tub 9 is sucked out from the drop portion 9 m into the drying duct 12, and when passing through the drying duct 12, water cooling and dehumidification is performed in the drying duct 12, and the lint filter is applied. It is carried out by collecting lint through (not shown), heating it with a heater 16, and then blowing it into the washing tub 8 from the first discharge port 18 or the second discharge port 22. Drying is performed while monitoring the temperature of warm air with a temperature sensor, and ends when the rate of temperature change reaches a predetermined value.

第１吐出口１８は外槽９の上面に位置し、衣類上面全体に風を当てる必要がある為、第２吐出口２２に比べて空気通過断面積は大きくなっている。その為、高速・高圧という効果は得られにくいものの、大風量で風を送り込むことが可能である。 Since the first discharge port 18 is located on the upper surface of the outer tank 9 and it is necessary to blow the entire upper surface of the clothes, the air passage cross-sectional area is larger than that of the second discharge port 22. Therefore, although it is difficult to obtain the effects of high speed and high pressure, it is possible to send wind with a large air volume.

第２吐出口２２は外槽９の側面下部に位置し、衣類を持ち上げて、押し広げる必要がある為、高速・高圧の風が吹き出せるように第１吐出口１８に比べて空気通過断面積は小さくなっている。 The second discharge port 22 is located at the lower part of the side surface of the outer tank 9, and it is necessary to lift and spread the clothes. Therefore, the air passage cross-sectional area is larger than that of the first discharge port 18 so that high-speed and high-pressure wind can be blown out. Is getting smaller.

乾燥運転時は風路切替部３０によって、適宜第１風路と第2風路の切替が行われる。 During the dry operation, the air passage switching unit 30 appropriately switches between the first air passage and the second air passage.

第１風路を介し、第１吐出口１８から風を送り込む際は、外槽９の上部から衣類の上面に向けて吹付ける。 When the wind is sent from the first discharge port 18 through the first air passage, it is blown from the upper part of the outer tub 9 toward the upper surface of the clothes.

洗濯槽である洗濯兼脱水槽８、または回転翼８ｂを回転させることにより衣類全体を撹拌しながら加熱させ乾燥を行う。 By rotating the washing / dehydrating tub 8 or the rotary blade 8b, which is a washing tub, the entire clothes are heated while being agitated and dried.

第２風路を介し、第２吐出口２２から風を送り込む際は、洗濯兼脱水槽８の回転を停止させて、温風吹き出し孔２３と第２吐出口２２とが対向した位置で静止させる。 When the air is sent from the second discharge port 22 through the second air passage, the rotation of the washing / dehydrating tub 8 is stopped, and the warm air outlet hole 23 and the second discharge port 22 are stopped at a position facing each other. ..

第２吐出口２２から吹出した風は吹出し孔２３より衣類に向けて下方向から吹付けられ、回転翼８ｂの回転と合わせて衣類が持ち上げられる。持ち上げられた衣類にさらに風が当たることによって、衣類が押し広げられ、乾燥中に発生するしわが低減する。 The wind blown from the second discharge port 22 is blown from below toward the clothes through the blow holes 23, and the clothes are lifted in accordance with the rotation of the rotary blades 8b. Further wind exposure to the lifted garment spreads the garment and reduces wrinkles that occur during drying.

このとき、第２吐出口２２が第１吐出口１８より後方にある為、送風ユニット１３に対し近い位置にあり、送風ユニットから送り出される風の圧力損失を比較的小さくすることが可能となる。 At this time, since the second discharge port 22 is behind the first discharge port 18, it is located close to the blower unit 13, and the pressure loss of the wind sent out from the blower unit can be made relatively small.

また、第２吐出口２２が第１吐出口１８より後方にある為、ヒータ１６に対し従来より近い位置にあり、ヒータ１６によって加熱された空気が、温度を比較的下げること無く、洗濯兼脱水槽８に吹き出すことが可能となる。 Further, since the second discharge port 22 is behind the first discharge port 18, it is located closer to the heater 16 than before, and the air heated by the heater 16 can be washed and removed without lowering the temperature relatively. It becomes possible to blow out to the water tank 8.

第２吐出口２２からは高速・高圧の風が吹き出されるため、吹出す際の騒音が大きくなる傾向がある。今回は第１吐出口１８より第２吐出口２２を本体後方に配置することにより、使用者から第２吐出口２２の位置を離すことにより、騒音を伝わりにくくすることが可能である。 Since high-speed, high-pressure wind is blown from the second discharge port 22, the noise at the time of blowing tends to be large. This time, by arranging the second discharge port 22 behind the main body from the first discharge port 18, it is possible to make it difficult for noise to be transmitted by separating the position of the second discharge port 22 from the user.

このような構成を備えた洗濯乾燥機において、次に本発明の特徴的な構成とその動作を説明する。図４は風路切替部３０の縦断面図であり、第２風路選択時の遮蔽板３１の位置を示している。図５は風路切替部３０の縦断面図であり、第１風路選択時の遮蔽板３１の位置を示している。図６は図５におけるＡ部を示す拡大図である。図７は遮蔽板３１の斜視図を示している。図８は風路切替部３０が送風ユニット１３に設けられた場合を示す斜視図である。 In the washer / dryer having such a configuration, the characteristic configuration of the present invention and its operation will be described next.

図４は第２風路選択時の風路切替部３０の断面図を示しており、図上方向から風が送り込まれている。遮蔽板３１は軸を介し、駆動モータ(図示省略)によって、適宜回転し、風路の切替を行っている。 FIG. 4 shows a cross-sectional view of the air passage switching portion 30 when the second air passage is selected, and the wind is sent from the upper direction of the drawing. The shielding plate 31 is appropriately rotated by a drive motor (not shown) via a shaft to switch the air passage.

第２風路選択時は高速・高圧の風を送り込む必要がある為、第１風路への漏れを極力無くす必要がある。その為、遮蔽板３１に傾斜を設け、第２風路へ風が流れやすいような構造としている。 When selecting the second air passage, it is necessary to send high-speed and high-pressure wind, so it is necessary to eliminate leakage to the first air passage as much as possible. Therefore, the shielding plate 31 is provided with an inclination so that the wind can easily flow into the second air passage.

また、図７の通り、遮蔽板３１の風が当たる面に傾斜を設ける。つまり、図上方向から風が流れてくるが、例えば、第２風路選択時、第２の風路の上流方向から下流方向に向けて傾斜を設けることにより、風が第２風路へ流れやすいような効果を持たせ、第１風路への漏れを抑制する効果を得ることが出来る。また、風路に凸部がありながらも、比較的風損を少なくすることが可能となる。 Further, as shown in FIG. 7, an inclination is provided on the surface of the shielding plate 31 where the wind hits. That is, the wind flows from the upper direction of the figure. For example, when the second air passage is selected, the wind flows to the second air passage by providing an inclination from the upstream direction to the downstream direction of the second air passage. It is possible to obtain an effect of easily suppressing leakage to the first air passage. Further, even though the air passage has a convex portion, it is possible to relatively reduce the wind damage.

図７に遮蔽板３１の斜視図を示す。遮蔽板３１には封止用のパッキン３２が周方向に組み込まれており、このパッキン３２が風路の内面に当接し、封止の役割を担っている。なお、パッキン３２の取付け形状はこれに限定されるものではなく、例えば、面接触等、その他の形状であってもよい。 FIG. 7 shows a perspective view of the shielding plate 31. A sealing packing 32 is incorporated in the shielding plate 31 in the circumferential direction, and the packing 32 comes into contact with the inner surface of the air passage and plays a role of sealing. The mounting shape of the packing 32 is not limited to this, and may be another shape such as surface contact.

遮蔽板３１に対して風路下流側、且つ遮蔽板３１に当接する風路内壁に漏れ防止部３３を設ける。これは、遮蔽板３１と当接する構造となっている。この漏れ防止部３３により、高速の風が遮蔽板３１に当たり、その風圧で遮蔽板３１が漏れ防止部３３に押し付けられるような状態となる為、漏れ防止の信頼性が向上する。 A leak prevention portion 33 is provided on the downstream side of the air passage with respect to the shielding plate 31 and on the inner wall of the air passage that abuts on the shielding plate 31. This has a structure in which it comes into contact with the shielding plate 31. The leakage prevention portion 33 causes a high-speed wind to hit the shielding plate 31, and the shielding plate 31 is pressed against the leakage prevention portion 33 by the wind pressure, so that the reliability of leakage prevention is improved.

また、風により遮蔽板３１が漏れ防止部３３に押し付けられるということは、遮蔽板３１が漏れ防止部によって支えられている為、高速の風によって、遮蔽板が押し込まれて軸部が破損するリスクを少なくすることが可能である。 Further, the fact that the shielding plate 31 is pressed against the leakage prevention portion 33 by the wind means that the shielding plate 31 is supported by the leakage prevention portion, so that there is a risk that the shielding plate is pushed by the high-speed wind and the shaft portion is damaged. Can be reduced.

図４は、第２風路洗濯時の風路切替部３０の断面図、図５は、第１風路選択時の風路切替部３０の断面図を示しており、図上方向から風が送り込まれている。 FIG. 4 is a cross-sectional view of the air passage switching portion 30 when washing the second air passage, and FIG. 5 is a cross-sectional view of the air passage switching portion 30 when the first air passage is selected. It has been sent.

第１風路は、第２風路に比べて大風量タイプである為、第２風路ほどの気密性の必要が無い。その為、第２風路選択時の遮蔽板３１下流側に設けた漏れ防止部３３は、第２風路上には設けない構造としている。第２風路選択時（図４参照）に、第２風路に凸部を設けないことで、風損がさらに少なくなり、第２風路の風の送風効率が良くなることで、高速・高圧の風を吹付けることが出来る。 Since the first air passage is a larger air volume type than the second air passage, it does not need to be as airtight as the second air passage. Therefore, the leak prevention portion 33 provided on the downstream side of the shielding plate 31 when the second air passage is selected is not provided on the second air passage. When the second air passage is selected (see FIG. 4), by not providing a convex portion in the second air passage, the wind damage is further reduced, and the air blowing efficiency of the wind in the second air passage is improved, so that the speed is increased. High pressure wind can be blown.

第１風路選択時は、第２風路上に漏れ防止部３３が無いものの、図４のように、一直線に風が通り抜ける為、遮蔽板３１に無理な負荷がかからず、故障するリスクも少い。 When the first air passage is selected, there is no leakage prevention unit 33 on the second air passage, but as shown in FIG. 4, the wind passes in a straight line, so that an unreasonable load is not applied to the shielding plate 31 and there is a risk of failure. There are few.

さらに、風が一直線に通り抜ける為、パッキン３２に掛かる圧力が軽減され、漏れる可能性も少なくなる。 Further, since the wind passes through in a straight line, the pressure applied to the packing 32 is reduced, and the possibility of leakage is reduced.

図６には、漏れ防止部３３の断面拡大図（図５のＡ部の拡大図）を示す。 FIG. 6 shows an enlarged cross-sectional view of the leakage prevention portion 33 (enlarged view of the portion A in FIG. 5).

第１風路に対して垂直に設けることで、遮蔽板３１が当接した際に、風が選択した風路以外の風路、ここでは図４の通り、第１風路に漏れることを抑止している。なお、漏れ防止部３３に傾斜を設けてもよい。 By providing it perpendicular to the first air passage, when the shielding plate 31 comes into contact with the air passage other than the selected air passage, it is prevented that the wind leaks to the first air passage as shown in FIG. doing. The leak prevention unit 33 may be inclined.

これらの構造により、従来のように、風路に漏れ防止部と当接部の２つの形状を設けなくても、風の漏れ防止の効果を得ることが可能となる。 With these structures, it is possible to obtain the effect of preventing wind leakage without providing the two shapes of the leakage prevention portion and the contact portion in the air passage as in the conventional case.

上記までの内容では、風路切替部３０を送風ユニットの外部に設けていたが、図８に示すように、送風ユニット１３内部に設けることも可能である。 In the above contents, the air passage switching unit 30 is provided outside the blower unit, but as shown in FIG. 8, it can also be provided inside the blower unit 13.

図８の送風ユニット１３は、ファンモータの回転により吹き出す風は、ヒータ１６を通って、第１風路への出力口である第１送風口４０と第２風路の出力口である第２送風口４１のいずれかに流れる。第１風路と第２風路のどちらに風を流すかは、風路切替部の遮蔽板３１の切り替えで制御される。また、ファンモータから吹き出す方向と垂直方向に、第１風路及び第２風路を設け、ファンモータの回転により吹き出された風は、第１風路の出力口と第２風路の出力口の手前の壁にあたって、第１の風路、第２風路へ流れる。 In the blower unit 13 of FIG. 8, the air blown out by the rotation of the fan motor passes through the heater 16 and is the first blower port 40 which is the output port to the first air passage and the second air outlet which is the output port of the second air passage. It flows to any of the air outlets 41. Whether the wind flows through the first air passage or the second air passage is controlled by switching the shielding plate 31 of the air passage switching portion. Further, the first air passage and the second air passage are provided in the direction perpendicular to the direction of blowing from the fan motor, and the wind blown out by the rotation of the fan motor is the output port of the first air passage and the output port of the second air passage. It hits the wall in front of and flows to the first air passage and the second air passage.

なお、遮蔽板３１を切り替える際に、風路上に凸形状の漏れ防止部３３、又は凹形状の漏れ防止部３３ａを設けることで、選択されなかった風路上に風が流れるのを防止することが出来る。この漏れ防止部の形状は、これらに限定するものでもなく、漏れを防止出来るものでれば、どのような形状でも良い。但し、風を流す際に風損が大きくならないように、風路に対して小さい、また傾斜などの形状にした方が望ましい。 When switching the shielding plate 31, it is possible to prevent the wind from flowing on the unselected air passage by providing the convex leakage prevention portion 33 or the concave leakage prevention portion 33a on the air passage. You can. The shape of the leakage prevention portion is not limited to these, and any shape may be used as long as it can prevent leakage. However, it is desirable that the shape is small with respect to the air passage and has a slope so that the wind damage does not increase when the wind flows.

以上のように、本発明によれば、信頼性の高い風路切替が可能で、且つ乾燥仕上がりの低下を抑止可能な洗濯機を提供することができる。 As described above, according to the present invention, it is possible to provide a washing machine capable of highly reliable air passage switching and capable of suppressing deterioration of the dry finish.
