The user operates the operation display unit 16 as necessary to set the desired operation content, start operation, It is possible to stop and recognize the progress of driving.
また、本第１の実施の形態におけるドラム式洗濯乾燥機には、回転ドラム４内に収容した洗濯物を乾燥する機能が設けられており、水槽３内の空気を排気して除湿し、加熱されて乾燥した温風にして再び水槽３内に送風する循環送風経路１７が形成されている。 Further, the drum type washing and drying machine in the first embodiment is provided with a function of drying the laundry accommodated in the rotary drum 4, and the air in the water tank 3 is exhausted to dehumidify and heat. Thus, a circulation air passage 17 is formed in which the warm air is dried and sent into the water tank 3 again.
循環送風経路１７は、図２および図３に示すように、送風加熱経路１８を有し、入り口側を熱交換板１９を配設した除湿部２０と出口側を水槽３の後面に設けられた温風供給口２１に接続する循環経路２２とにより形成されている。送風加熱経路１８には、送風ファン（送風手段）２３とヒータ（加熱手段）２４とが内蔵されている。 As shown in FIGS. 2 and 3, the circulation air flow path 17 has a air flow heating path 18, and a dehumidifying part 20 provided with a heat exchange plate 19 on the inlet side and an outlet side provided on the rear surface of the water tank 3. It is formed by a circulation path 22 connected to the hot air supply port 21. A blower fan (blower unit) 23 and a heater (heating unit) 24 are built in the blower heating path 18.
本体１の前面には洗剤投入ケース２８が設けられ、水槽３内には、乾燥時の循環風路を形成し、除湿部２０と連通する排気口２９が設けられている。水槽３の上部には、循環送風経路１７と除湿部２０とを接続する第１の接続ホース３１が設けられ、循環送風経路１７の入口には、糸屑回収装置３２が設けられている。循環送風経路１７の出口側には、温風供給口２１と連通する循環経路２２と接続するために第２の接続ホース３３が設けられている。 A detergent charging case 28 is provided on the front surface of the main body 1, and an exhaust port 29 that forms a circulation air passage during drying and communicates with the dehumidifying unit 20 is provided in the water tank 3. A first connection hose 31 that connects the circulating air passage 17 and the dehumidifying unit 20 is provided at the upper part of the water tank 3, and a yarn waste collecting device 32 is provided at the inlet of the circulating air passage 17. A second connection hose 33 is provided on the outlet side of the circulation air passage 17 in order to connect to the circulation passage 22 communicating with the hot air supply port 21.
送風加熱経路１８と循環経路２２との接続開口部２５には、接続開口部２５と略同形状の封口部材２６が回動自在に回動軸２７を介して係止されている。封口部材２６は、送風ファン２３が停止している状態では封口部材２６が接続開口部２５を閉塞するように位置し、送風ファン２３が回転している状態では、その送風ファン２３の風圧により封口部材２６が回動軸２７を中心として回動し、接続開口部２５を開放するように、回動軸２７を境界とした左右の重量バランスとしている。 A sealing member 26 having substantially the same shape as that of the connection opening 25 is engaged with the connection opening 25 between the blower heating path 18 and the circulation path 22 via a rotation shaft 27 so as to be rotatable. The sealing member 26 is positioned so that the sealing member 26 closes the connection opening 25 when the blower fan 23 is stopped, and is sealed by the wind pressure of the blower fan 23 when the blower fan 23 is rotating. The left and right weight balance with the rotation shaft 27 as a boundary is set so that the member 26 rotates about the rotation shaft 27 and the connection opening 25 is opened.
具体的には、図３および図４に示すように、封口部材２６は、送風加熱経路１８を下面側から見たときに回動軸２７を境界として、右側即ち送風ファン２３による風の流れ方向の下流側で接続開口部２５を開放する側に駆動する側であるＡ部分の投影面積Ｓａは、その反対側であるＢ部分の投影面積Ｓｂより大きくなる（Ｓａ＞Ｓｂ）ように形成しており、Ｂ部分の下側面上には、Ａ部分の重量ＷａよりＢ部分の重量Ｗｂが重くなる（Ｗｂ＞Ｗａ）ように錘３５を設けている。 Specifically, as shown in FIGS. 3 and 4, the sealing member 26 has a rotating shaft 27 as a boundary when the blower heating path 18 is viewed from the lower surface side, that is, the flow direction of the wind by the blower fan 23. The projected area Sa of the A portion, which is the side that drives the connection opening 25 on the downstream side, is larger than the projected area Sb of the B portion on the opposite side (Sa> Sb). A weight 35 is provided on the lower surface of the B portion so that the weight Wb of the B portion is heavier than the weight Wa of the A portion (Wb> Wa).
この構成により、送風ファン２３が停止している場合は、Ａ部分の重量ＷａよりＢ部分の重量Ｗｂが重いので、封口部材２６が接続開口部２５を閉塞する状態となる。一方、送風ファン２３が回転駆動している場合は、Ａ部分の投影面積ＳａがＢ部分の投影面積Ｓｂより大きいので、送風ファン２３の風圧によって、Ａ側に作用する押圧力Ｐａが、Ｂ側に作用する押圧力Ｐｂに対し大きくなる（Ｐａ＞Ｐｂ）ので、封口部材２６は、破線矢印のように、接続開口部２５を開放する側に回動する。また、Ａ部分が風の流れ方向の下流側にあり、Ｂ部分が風の流れ方向の上流側にあるので、封口部材２６が開いた状態にあるとき、風の流れが、Ａ部分の上側面を押すとともに、Ｂ部分の下側面をも押して開く状態に維持することにより、接続開口部２５の全面を使って風が流れることができる。 With this configuration, when the blower fan 23 is stopped, the weight Wb of the B portion is heavier than the weight Wa of the A portion, so that the sealing member 26 closes the connection opening 25. On the other hand, when the blower fan 23 is rotationally driven, the projection area Sa of the A portion is larger than the projection area Sb of the B portion, so that the pressing force Pa acting on the A side by the wind pressure of the blower fan 23 is changed to the B side. (Pa> Pb), the sealing member 26 rotates to the side that opens the connection opening 25 as indicated by the broken line arrow. Further, since the portion A is on the downstream side in the wind flow direction and the portion B is on the upstream side in the wind flow direction, when the sealing member 26 is in the open state, the wind flow is While pressing and maintaining the state where the lower surface of the B portion is also pushed open, the wind can flow using the entire surface of the connection opening 25.
また、図４に示すように、封口部材２６の回動軸２７の軸方向の端面３６は、略平面形状とし、その端面３６に対向する接続開口部２５側の対向面３７も略平面形状とし、対向する面同士が互いに略平面形状となるようにしている。これにより、送風ファン２３の風圧による封口部材２６の回動動作時に平面同士で接触するため、回動動作は円滑に行われる。 As shown in FIG. 4, the end surface 36 in the axial direction of the rotation shaft 27 of the sealing member 26 has a substantially planar shape, and the facing surface 37 on the side of the connection opening 25 facing the end surface 36 also has a substantially planar shape. The opposing surfaces are substantially planar with each other. Thereby, since the flat surfaces come into contact with each other when the sealing member 26 is rotated by the wind pressure of the blower fan 23, the rotating operation is performed smoothly.
次に動作及び作用を説明する。 Next, the operation and action will be described.
扉９を開いて回転ドラム４内に洗濯物を投入して運転を開始させると、注水弁１４が開き、洗剤投入ケース２８内に水が注水され、その中に投入されていた洗剤を流しながら、注水管路（図示せず）を介して、水槽３内に所定量の注水がなされ、モータ１２により回転ドラム４が回転駆動されて洗濯行程が開始される。洗濯行程の洗濯物は、回転ドラム４の回転により、撹拌突起１１によって回転方向に持ち上げられ落下する撹拌動作が繰り返され、いわゆる叩き洗いの作用が及んで洗濯がなされる。 When the door 9 is opened and the laundry is put into the rotating drum 4 to start the operation, the water injection valve 14 is opened, water is poured into the detergent charging case 28, and the detergent that has been poured therein is flowing. A predetermined amount of water is injected into the water tank 3 through a water injection line (not shown), and the rotary drum 4 is driven to rotate by the motor 12 to start the washing process. The laundry in the washing process is repeatedly washed by the rotation of the rotating drum 4 and is repeatedly lifted in the rotational direction by the stirring protrusion 11 and dropped, and the so-called tapping action is performed.
このとき、洗剤量が著しく多量に投入されていたり洗剤の種類によっては、回転ドラム４の撹拌突起１１による回転方向に持ち上げられ落下する洗濯物の撹拌動作の繰り返しによる泡立ちが多量となってしまう場合があり、この泡は、水槽３の後面に設けられた温風供給口２１から循環経路２２を経て送風加熱経路１８内に流入し、ヒータ２４や送風ファン２３の駆動部２３ａに付着し、腐食させたり絶縁性能を劣化させたりする恐れがある。 At this time, when the amount of detergent is remarkably large, or depending on the type of detergent, foaming due to repeated stirring operation of the laundry that is lifted and dropped by the stirring protrusion 11 of the rotating drum 4 becomes large. This bubble flows from the hot air supply port 21 provided on the rear surface of the water tank 3 through the circulation path 22 into the blower heating path 18 and adheres to the heater 24 and the drive unit 23a of the blower fan 23 to corrode. Or the insulation performance may be degraded.
しかしながら、本実施の形態では、洗濯行程中においては、送風加熱経路１８の循環経路２２との接続部である接続開口部２５に封口部材２６を設けており、このとき送風ファン２３は停止した状態であるので、封口部材２６は接続開口部２５を閉塞するように位置している。これにより、封口部材２６と接続開口部２５との間は、ほとんど隙間のない状態となっているので、洗剤泡の侵入を防止することができる。この後、後述する乾燥行程で、ヒータ２４に通電され加熱される際に、ヒータ２４に洗剤泡等の付着がないため、異臭の発生がなく、安心し使用することができる。また、ヒータ２４や送風ファン２３の駆動部２３ａが腐食したり、その絶縁性能が劣化したりすることを防止することができる。 However, in the present embodiment, during the washing process, the sealing member 26 is provided in the connection opening 25 which is the connection portion of the blower heating passage 18 with the circulation passage 22, and the blower fan 23 is stopped at this time. Therefore, the sealing member 26 is positioned so as to close the connection opening 25. Thereby, since there is almost no gap between the sealing member 26 and the connection opening 25, it is possible to prevent the detergent bubbles from entering. Thereafter, when the heater 24 is energized and heated in the drying process described later, the heater 24 does not have detergent bubbles or the like attached thereto, so that no strange odor is generated and the heater 24 can be used with confidence. Moreover, it can prevent that the heater 24 and the drive part 23a of the ventilation fan 23 corrode, or that the insulation performance deteriorates.
次に、所要の洗濯時間の後、排水弁１５が開き、汚れた洗濯液は排水管路１３から排出され、回転ドラム４を高速回転させる脱水動作により洗濯物に含まれた洗濯液を脱水し、その後、水槽３内に注水管路（図示せず）から注水され、すすぎ行程が実施される。このすすぎ行程においても、洗濯物には回転ドラム４の回転により、撹拌突起１１で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洗いが実施される。すすぎ行程が終了すると、回転ドラム４を高速回転させて脱水する脱水行程が実行される。 Next, after a required washing time, the drain valve 15 is opened, the dirty washing liquid is discharged from the drain pipe 13, and the washing liquid contained in the laundry is dehydrated by a dehydrating operation that rotates the rotating drum 4 at a high speed. Then, water is poured into a water tank 3 from a water injection pipe (not shown), and a rinsing process is performed. Also in the rinsing process, the laundry is rinsed by repeating the stirring operation of being lifted and dropped by the stirring protrusion 11 by the rotation of the rotating drum 4. When the rinsing process is completed, a dehydration process is performed in which the rotating drum 4 is rotated at a high speed to perform dehydration.
上記の脱水行程が終了すると、乾燥行程に移行する。乾燥行程においては、回転ドラム４を所定回転数で回転駆動し、撹拌突起１１によって洗濯物を回転方向に持ち上げて落下させる撹拌動作が繰り返されるとともに、以下の手順によって、内部の空気を除湿および加熱を行い、洗濯物を乾燥させる。 When the dehydration process is completed, the process proceeds to the drying process. During the drying process, the rotating drum 4 is driven to rotate at a predetermined number of rotations, and the stirring operation for lifting and dropping the laundry in the rotational direction by the stirring protrusion 11 is repeated, and the internal air is dehumidified and heated by the following procedure. And dry the laundry.
すなわち、循環送風経路１７内に配設された送風加熱経路１８内に設けられた送風ファン２３を回転駆動することにより、封口部材２６が送風ファン２３の風圧により回動して接続開口部２５を開放状態となる。循環送風経路１７には空気の流れが発生し、洗濯物を収容した回転ドラム４内の湿った空気は透孔１０を通じて、水槽３内に入り、水槽３の排気口２９から除湿部２０に排気される。除湿部２０には、注水弁１４から供給される水の噴霧等により冷却された熱交換板１９が配設され、水槽３内から排気された湿った空気は、熱交換板１９上を通過する間に冷却され水分が結露して除湿される。 That is, by rotating and driving the blower fan 23 provided in the blower heating path 18 provided in the circulation blower path 17, the sealing member 26 is rotated by the wind pressure of the blower fan 23, thereby opening the connection opening 25. It becomes an open state. An air flow is generated in the circulation air passage 17, and the moist air in the rotating drum 4 containing the laundry enters the water tank 3 through the through holes 10 and exhausts from the exhaust port 29 of the water tank 3 to the dehumidifying unit 20. Is done. The dehumidifying unit 20 is provided with a heat exchange plate 19 cooled by spraying water supplied from the water injection valve 14, and the humid air exhausted from the water tank 3 passes over the heat exchange plate 19. Cooled in between, moisture is condensed and dehumidified.
除湿された空気は、第１の接続ホース３１を通り、糸屑回収装置３２を通過して乾燥運転中に発生した糸屑等のリント類が除去された後、送風加熱経路１８に入り、さらに、ヒータ２４で加熱され乾いた温風となって、第２の接続ホース３３を通った後、温風供給口３４から水槽３に送り込まれ、その後、回転ドラム４内へ循環供給される。この空気の循環が所要時間繰り返され、洗濯物に含まれた水分が徐々に奪われて乾燥が進行する。 The dehumidified air passes through the first connection hose 31, passes through the lint collecting device 32, and lints such as lint generated during the drying operation are removed, and then enters the blast heating path 18. The hot air is heated by the heater 24 and dried, passes through the second connection hose 33, is then fed into the water tank 3 through the hot air supply port 34, and is then circulated and supplied into the rotating drum 4. This air circulation is repeated for a required time, and moisture contained in the laundry is gradually taken away and drying proceeds.
以上のように、本実施の形態のドラム式洗濯機は、封口部材２６が、送風ファン２３の駆動と連動して回動することにより、接続開口部２５を開閉するので、封口部材２６は、乾燥行程時においては空気の流れの抵抗になることなく、また、洗濯行程時においては送風加熱経路１８内への洗剤泡の侵入を防止することができる。 As described above, in the drum-type washing machine of the present embodiment, the sealing member 26 opens and closes the connection opening 25 by rotating in conjunction with the driving of the blower fan 23. During the drying process, there is no resistance to air flow, and it is possible to prevent the detergent bubbles from entering the blower heating path 18 during the washing process.
以上のように、本発明にかかるドラム式洗濯乾燥機は、使用者が誤って洗剤を入れすぎて、洗剤泡が異常に発生しても、送風加熱経路内の加熱手段および送風手段への洗剤泡の進入を防止できるので、泡浸漬による異臭の発生の防止し、また、加熱手段および送風手段の信頼性を確保することできるので、洗剤の浸漬と信頼性を要する部品を搭載した各種機器に適用できる。 As described above, the drum-type washing and drying machine according to the present invention has the detergent in the heating heating path and the blowing means even if the user mistakenly puts in too much detergent and detergent bubbles are abnormally generated. Since the ingress of foam can be prevented, the generation of off-flavors due to foam immersion can be prevented, and the reliability of heating means and air blowing means can be ensured, so various devices equipped with parts that require detergent immersion and reliability can be used. Applicable.
