水槽内に回転自在に配した回転ドラム内に洗濯物を投入して回転ドラムを回転駆動することにより、洗濯工程、すすぎ工程、脱水工程を順次実行して洗濯物を洗浄するドラム式洗濯機が構成され、このドラム式洗濯機に乾燥機能を設けることにより、脱水工程を終えた洗濯物を乾燥する乾燥工程を実行することができるドラム式洗濯乾燥機に構成することができる。 The laundry to rotatably arranged rotary within the drum was charged to a rotary drum driven to rotate in the water tank, a washing step, rinsing step, the drum type washing machine for washing laundry by performing a dehydration step sequentially is is constituted by providing a drying function to the drum type washing machine may be configured in a drum type washing and drying machine capable of performing a drying process for drying the laundry after the dehydration step.

乾燥機能は、水分を含む洗濯物が収容された回転ドラム内と空気流通する水槽内の湿気を含んだ空気を槽外に排気して除湿手段により空気中の湿気を除湿した後、加熱手段によって加熱乾燥させた温風にして再び水槽内に送風するように構成され、湿気を含む空気が排気され、乾燥した温風が送風される空気循環が継続されることにより、回転ドラム内の洗濯物は乾燥される(特許文献1参照)。 Drying function, after dehumidified moisture in the air by the exhaust to dehumidifier air containing moisture of the laundry is in the water tank that circulates within the air rotating drum housed in Sogai containing water, by the heating means is configured to blow the heated dried warm air is again in the water tank, air containing moisture is evacuated, by the air circulation is continued to dry hot air is blown, the laundry in the rotary drum It is dried (see Patent Document 1).
特開平10−235093号公報(第2〜4頁、図1) JP 10-235093 discloses (second to fourth pages, Fig. 1)

回転ドラムはその周面全体に水及び空気が通過できる透孔が多数形成されているため、この回転ドラムを収容する水槽内から排気すると、水分を含む洗濯物を収容した回転ドラム内の湿気を含む空気は前記透孔を通過して水槽内から槽外に排出される。 Since the rotary drum is the hole in which water and air can pass to the entire circumferential surface is formed a large number, when the exhaust from the water tank for accommodating the rotary drum, the moisture in the rotary drum containing the laundry containing moisture air containing is discharged to the outside of the tank from the water tank through said hole. 一方、排気した湿気を含む空気から除湿し加熱乾燥させた温風を回転ドラム内に送風するとき、単に水槽内に送風しても湿気を含む排気と混合して乾燥能力が低下してしまうため、従来技術においては、回転ドラム内から洗濯物を出し入れするために開口している回転ドラムの正面開口部から温風を回転ドラム内に送風している。 Meanwhile, when the blowing hot air heat-dried dehumidifies the air containing evacuated moisture in a rotating drum, simply because the mixture to drying capacity and exhaust gas containing moisture be blown into the water tank drops in the prior art, it is blown from the front opening of rotary drum which is open for loading and unloading the laundry from the rotary drum hot air into the rotary drum.

しかし、回転ドラムの正面開口部の直前には、それに対向して洗濯物を出し入れする際に開閉する扉体が設けられているため、加熱された空気が回転ドラム内にその正面開口部から送風されると、扉体にも加熱された空気が当たるため扉体が温度上昇し、手で触れることもできないほどに熱くなる。 However, just before the front opening of the rotary drum, moreover, due to the door body for opening and closing into and out opposite to the laundry is provided, blowing heated air from a front opening in the rotary drum Once also the door body for the heated air hits is increased temperature to the door body, becomes hot enough can not be touched by hand. 洗濯乾燥機では洗濯物が完全に乾燥するまで乾燥工程を継続するだけでなく、乾燥工程の途中で扉体を開いて生乾き状態の洗濯物を回転ドラム内から取り出し、後は天日干しによって完全乾燥させることにより、乾燥工程に要する電力消費を節減する使い方や、アイロン掛けする衣類などでは生乾きの方が好都合なので乾燥途中で衣類を取り出す使い方など、ユーザが自由に扉体を開くことができるように構成されるので、加熱空気の送風により扉体が高い温度にまで加熱されてしまうようでは、扉体を自由に開くことができる利点は生かすことはできない。 The washing and drying machine not only the laundry continues to drying to complete dryness, in the course of the drying process by opening the door body taken out laundry half-dry state from the rotary drum, completely dried by the sun after by, use and to reduce power consumption required for drying, such as how to take out clothes in the middle dried so convenient found the following half-dry in such clothing ironing, so that the user can open the free door since the structure, as will be heated to the door body is high temperature by the blowing of the heated air can not be the take advantage of being able to open the door body freely.

また、従来技術においては、振動体側である水槽と固定体側である除湿手段とをホースで接続しているため、振動等、何らかの理由でホースが外れてしまうと、水槽内の水が漏れてしまうといった課題があった。 Further, in the prior art, because it connects the dehumidifying means is a water tank and a fixed body side, which is a vibration member side hose, vibration or the like, the hose for some reason deviates, leaks of water in the water tank there is a problem.

さらに、従来技術においては、乾燥機能のための空気循環経路を水槽の外部周辺にダクトを配し、その要所に送風ファンや除湿手段などを構成しているため、乾燥機能を構成するための構成要素が筐体内に占める体積が大きくなり、ドラム式洗濯乾燥機が無駄に大型化してしまう課題があった。 Further, in the prior art, the air circulation path for the drying function arranges the duct around the outside of the aquarium, because they constitute such blower fan and dehumidifying means to the key point, for constituting a drying function components is increased is the volume occupied in the housing, there is a problem that the drum type washing and drying machine becomes large in vain.

本発明が目的とするところは、回転ドラム内から排気した湿気を含む空気から効率よく除湿する除湿構造を備えたドラム式洗濯乾燥機を提供することにある。 When the present invention is intended to provide a with a dehumidifying structure dehumidifier efficiently from the air containing moisture is evacuated from the rotary drum drum type washing and drying machine.

上記目的を達成するために本発明に係るドラム式洗濯乾燥機は、有底円筒形の周面及び底面に多数の透孔が形成された回転ドラムを回転自在に収容する水槽が筐体内に配設され、有底円筒形に形成された水槽本体の外周面円筒軸方向に、開口端側から底面側に向けて貫通する送風ダクトと、底面側が閉じられ開口端側が開口する除湿ダクトとが、互いに隣接すると同時に水槽に隣接して形成され、水槽の前記除湿ダクトが隣接する周面に除湿ダクト内に通じる排気口が円筒軸方向に開口し、除湿ダクト内に外部から給水された流水により冷却される熱交換器が配設され、前記水槽本体の開口端側に、回転ドラム内に通じる洗濯物出入口と、除湿ダクトの開口端から送風ダクトの開口端に向かう空気流路を形成する連通流路と、この連通流路と Drum type washing and drying machine according to the present invention in order to achieve the above object, a water tank for rotatably accommodating the rotary drum a large number of through holes are formed on the peripheral surface and the bottom surface of the bottomed cylindrical distribution in the enclosure is set on the outer peripheral surface the cylindrical axis direction of the tank body formed in a bottomed cylindrical shape, and the blower duct penetrating toward the bottom face side from the opening end side, and a dehumidifying duct opening end side bottom side is closed is opened, is formed adjacent to the adjacent and at the same time the water tank to each other, wherein the dehumidifying duct outlet leading to the dehumidification duct in a circumferential surface adjacent the aquarium opened in the cylindrical axis direction, cooled by flowing water, which is water from the outside into the dehumidifying duct is the heat exchanger disposed to be on the opening end side of the tub body, communicating fluid to form a laundry entrance leading to the rotary drum, the air flow path toward the open end of the air duct from the open end of the dehumidifying duct a road, and the communication passage 風ダクトとの連結部位に向けて前記洗濯物出入口の周縁部から挿脱可能に装着された除塵フィルタとを備えた水槽蓋体が取り付けられ、水槽本体の外底面に、送風ダクトの底面側開口部と水槽底面に開口する送風口との間の空気流路を形成し、内部に送風ファン及びヒータを備えた加熱ダクトが取り付けられて前記水槽が構成され、前記筐体の水槽及び回転ドラムの開口端に対向する面に開閉自在に扉体が設けられてなることを特徴とする。 Aquarium lid and a removably loaded dust filter from the peripheral edge of the laundry entrance toward the coupling site of the wind ducts are mounted, the outer bottom surface of the tank body, the bottom side opening of the air duct parts and forms an air flow path between the blower port opening into the water tank bottom, the heating duct comprising a blower fan and a heater therein is constructed is the water tub mounted, aquarium and the rotary drum of the housing door openably on a surface facing the open end, characterized in that is provided.

回転ドラム2内に乾燥対象物が投入されて乾燥運転が開始されると、送風ファン15及びヒータ20に通電され、注水弁53が開かれて熱交換器51に冷却水が注水される。 When the drying operation is drying object in the rotary drum 2 is turned is started, electric power is supplied to the blowing fan 15 and the heater 20, the cooling water is water injection water injection valve 53 is open and the heat exchanger 51. 送風ファン15の回転により空気循環経路に空気の流れが発生する。 Air flow is generated in the air circulation path by the rotation of the blower fan 15. 回転ドラム2の周面には多数の透孔8が形成され、底面には水槽3に形成された送風口22に対向する円周上に複数の通気口39が形成されているので、図2に空気の循環経路を白抜き矢印として示すように、回転ドラム2内を通る空気循環路が形成される。 The peripheral surface of the rotary drum 2 is large number of through holes 8 are formed, a plurality of vent holes 39 are formed on the circumference facing the blower opening 22 formed in the water tank 3 in the bottom, FIG. 2 the circulation path of the air as indicated outlined arrow, the air circulation path passing through the rotary drum 2 is formed.

回転ドラム2内の湿気を含む空気は排気口21から除湿ダクト16内に排気され、除湿ダクト16内に配設された熱交換器51により排気された空気中の湿気は除湿される。 Air containing moisture in the rotary drum 2 is discharged to the dehumidifying duct 16 from the exhaust port 21, the moisture in the air exhausted by the heat exchanger 51 disposed in the dehumidifying duct 16 is dehumidified. 熱交換器51には注水ノズル52から注水される水が流れて冷却されているため、排気口21から排気された水槽3内の空気は冷却されることにより水蒸気が凝結して除湿される。 Because the heat exchanger 51 is cooled by the flow of water that is water injection from the injection nozzle 52, the air in the water tank 3, which is exhausted from the exhaust port 21 is water vapor is dehumidified by condensation by being cooled. 熱交換器51に注水された冷却水及び凝結によって生じた水は、図2に破線矢印で示すように、除湿ダクト16から水槽3内を流れて排水管路13から外部に排出される。 Water produced by the cooling water and condensed, which is water injection in the heat exchanger 51, as indicated by a dotted arrow in FIG. 2, and is discharged to the outside from the drain line 13 flows through the water tank 3 from the dehumidifying duct 16.

除湿ダクト16内で除湿された空気は連通流路16aを通り、送風ダクト18の入口に配設された除塵フィルタ17を通過する際に空気中に混入した糸屑等のリントが濾過され、送風ダクト18から水槽3の底面側に流れる。 Air dehumidified by the dehumidifying duct within 16 passes through the communication passage 16a, lint yarn waste or the like mixed in the air when passing through the dust filter 17 disposed in the inlet of the air duct 18 is filtered, blown flowing from the duct 18 to the bottom side of the water tank 3. 送風ダクト18は水槽3の背面側に配設された加熱ダクト19に空気を案内するための管路で、加熱ダクト19の送風ダクト18との連結部位に設けられた送風ファン15により乾燥用空気循環経路に一方通行の空気の流れが形成される。 Air duct 18 in the heating duct 19 disposed on the rear side of water tub 3 in line for guiding the air, dry air by the blowing fan 15 provided at a connection portion extending between the air duct 18 of the heating duct 19 on the other hand the flow of traffic in the air are formed in the circulation path.

前記加熱ダクト19内にはヒータ20が配設され、送風ダクト18から流れてきた空気を加熱して水槽3内に通じる送風口22から加熱乾燥した温風として水槽3内に送風する。 Said in the heating duct 19 heater 20 is disposed, it is blown into the water tank 3 as hot air heated and dried from the air outlet 22 to heat the air flowing from the air duct 18 leading to the water tank 3. 加熱ダクト19には送風口22から送風される空気温度を検出する温度センサ55が配設され、検出された送風空気の温度によりヒータ20による加熱温度が調節できるように構成されている。 The heating duct 19 is temperature sensor 55 is arranged to detect the temperature of the air blown from the air blowing port 22, and is configured to adjust the heating temperature by the heater 20 by the detected temperature of the blown air. また、加熱ダクト19にはヒータ20の異常過熱状態を検出してヒータ20への通電を遮断する温度ヒューズ27や、送風口22から逆流した水や泡が送風ファン15側に流入する溢水水位を検出する溢水水位センサ29が配設されている。 Also, and thermal fuse 27 to cut off the energization to the heater 20 to detect an abnormal overheating of the heater 20 in the heating duct 19, the overflow water level backflow water and bubbles from entering the blower fan 15 side from the air blowing port 22 overflow water level sensor 29 to be detected is disposed.

送風口22から水槽3内に送風された空気は回転ドラム2の底面に形成された通気口39や透孔8から回転ドラム2内に流入するので、除湿加熱された空気により洗濯物から水分が奪い取られ、再び排気口21から除湿ダクト16に排気されるので、回転ドラム2の回転による攪拌により全ての洗濯物の乾燥が促進され、この空気循環が所定時間繰り返されることにより洗濯物の乾燥がなされる。 Since air from the air blowing port 22 is blown into the tub 3 flows from the rotating drum 2 in the bottom vents 39 and holes 8 formed in the rotary drum 2, water from the laundry by dehumidified heated air deprived, so is exhausted to the dehumidifying duct 16 from the exhaust port 21 again, dry all the laundry is promoted by agitation by rotation of the rotary drum 2, the drying of the laundry by the air circulation is repeated a predetermined time It is made.

加熱された空気を水槽3内に送風する送風口22は、水槽3の底面下方寄りに形成されているので、回転ドラム2の回転により攪拌される乾燥対象物の中に加熱された空気が吹き込まれるため、乾燥対象物に加熱された空気が満遍なく触れる状態が得られて乾燥効率を向上させることができる。 Air blowing port 22 for blowing the heated air into the water tank 3 and is formed in the bottom lower side of the water tank 3, the air heated in the drying object to be agitated by the rotation of the rotary drum 2 is blown it is therefore possible to state that air heated to the drying object touches evenly improves the drying efficiency obtained. また、送風ファン15が送風口22に近い位置に配設されていることによって流路抵抗が少ない状態で水槽3内に送風することができ、効率のよい加熱空気の送風が可能となる。 Further, the blower fan 15 can be blown into the water tank 3 with the flow path resistance is small by being disposed in a position closer to the air blowing port 22, it is possible to blow a good heating air efficiently.

上記乾燥工程を実施するための構成において、排気口21は水槽本体3aの円筒軸方向に長く開口しているため排気口面積を大きく形成でき、排気抵抗を減らして風量を大きくとることができ、その結果、熱交換による除湿効果を高めることができる。 In the configuration for carrying out the drying process, the exhaust port 21 is a water tank body 3a longer open to the cylindrical axis outlet area can a larger order has to, by reducing the exhaust resistance can be a large air volume, As a result, it is possible to increase the dehumidification effect by heat exchange. また、排気口21は水槽本体3aの円弧接線方向に開口させることができるので、すすぎ工程時に回転ドラム2の回転に伴って飛散する水が除湿ダクト16内に流入して、乾燥工程時に除湿ダクト16内に付着した糸屑等のリントを洗い流すことができる。 Further, since the exhaust port 21 can be opened in an arc tangentially of the tank main body 3a, and flows into the rinsing process rotary drum water dehumidifying duct 16 scattered with the rotation of the two at the time, except during the drying process moisture duct it can be washed away lint yarn waste or the like attached to the 16.

また、除塵フィルタ17を洗濯物出入口11から挿脱できる位置に設けることができるので、ドラム式洗濯乾燥機1を使用する前後に開閉する扉体9を開けば目に付く位置に除塵フィルタ17の取っ手17aがあり、フィルタの清掃を怠りなく実行させるのに好適な状態が得られる。 Further, it is possible to provide a position capable of inserting and removing the dust filter 17 from the laundry entrance 11, the noticeable position opening the door 9 for opening and closing around the use of drum-type washing and drying machine 1 for dust removal filter 17 There is a handle 17a, a suitable condition can be obtained to support execution without neglect cleaning of the filters.

以上の説明の通り本発明により、水槽の外周部と一体にコンパクトに乾燥工程を実施するための構成要素を配置することができ、水漏れの恐れを軽減し、かつ大型化を伴うことなくドラム式洗濯乾燥機を構成することができる。 The present invention as explained above, the drum without can place components for carrying out the compact drying step together with the outer peripheral portion of the water tub, to reduce the risk of water leakage, and involves large it is possible to construct a expression washer dryer. また、回転ドラム内からの排気及び回転ドラム内への送風が円滑になされるため、乾燥効率のよい乾燥工程を実施することができるドラム式洗濯乾燥機を提供することができる。 Further, since the air from the rotary drum to the exhaust and the rotary drum of is made smoothly, it is possible to provide a drum type washing and drying machine capable of carrying out the drying efficient drying process.
