Description
本発明は，洗濯機および洗濯乾燥機に関するものである。 The present invention relates to a washing machine and a washing / drying machine.
洗濯乾燥機による衣類の乾燥は，送風ファンと熱源により高温・低湿度の空気を作り，これを洗濯槽内に吹込み，衣類の温度を高くし，衣類から水分を蒸発させ，蒸発した水分を機外へ排出することにより行う。 Drying clothes with a washing dryer creates high-temperature and low-humidity air with a blower fan and a heat source and blows it into the washing tub to raise the temperature of the clothes, evaporate the moisture from the clothes, and remove the evaporated moisture. This is done by discharging outside the machine.
蒸発した水分の除去方法としては，洗濯乾燥機外へ排出する排気式（常に新しい空気を供給）と，蒸発した水分を冷やし結露させて水分を除去する除湿式（同じ空気を循環させる）として水冷や空冷，ヒートポンプを用いた熱交換式がある。加えて，時間の短縮，使用水量や消費電力量を低減するため，乾燥工程の前半に除湿式乾燥を行い，後半に排気式乾燥を行う方式がある。 There are two methods for removing the evaporated water: an exhaust type that is discharged outside the washing dryer (always supplying new air) and a dehumidifier that cools the evaporated water to condense and removes the water (circulates the same air). There are also heat exchange types using air cooling and heat pumps. In addition, in order to shorten time and reduce the amount of water used and power consumption, there is a method in which dehumidification drying is performed in the first half of the drying process and exhaust drying is performed in the second half.
排気式は洗濯物に吹付けた後の温風空気をそのまま排気するため，時間短縮と使用水量や消費電力の低減を図ることはできるが，洗濯乾燥機周囲の室内に湿度の高い空気をそのまま排気してしまい，室内の環境を悪化させてしまう。 The exhaust type exhausts warm air after being blown to the laundry as it is, so it can save time and reduce the amount of water used and power consumption. However, humid air remains in the room around the washer / dryer. Exhaust will cause the indoor environment to deteriorate.
そこで，特許文献１に記載の洗濯乾燥機は，ヒートポンプ装置と，送風路と，外気を吸入する吸気口と，排水部を備え，乾燥行程において，前記排水部から送風路内の空気を排気するように構成したものである。これにより，多湿の空気を洗濯乾燥機が設置されている空間に放出し，環境を悪化させるのを防止している。 Therefore, the washing and drying machine described in Patent Document 1 includes a heat pump device, a blower passage, an intake port for sucking outside air, and a drainage unit, and exhausts air in the blower channel from the drainage unit in a drying process. It is comprised as follows. As a result, humid air is released into the space where the washing and drying machine is installed, preventing the environment from deteriorating.
しかしながら，排水部から排気するためには，排水部の先に設けてある排水トラップの水を抜く必要がある。排水トラップの水を抜くことで排気が可能となるが，その状態のまま運転を終了すると，排水口の臭いが排水トラップで抑止できなくなるため，本体内に臭気が入ってしまう。そこで，特許文献２に記載の洗濯乾燥機は，乾燥運転中に，ヒータの通電を停止して外槽上面から筐体との空間の空気を送風路に吸込み，回転ドラムから出た空気の全部または一部を排水ホースから排水口に排出する。また，乾燥運転の最後又は終了後に，排水ホースの圧力を確保しながら排水ホースを経由して，水を供給する，方法が提案されている。 However, in order to exhaust from the drainage section, it is necessary to drain the drainage trap provided at the end of the drainage section. The water can be exhausted by draining the drain trap, but if the operation is terminated in that state, the odor at the drain outlet cannot be suppressed by the drain trap, and odor enters the main body. Therefore, the washing and drying machine described in Patent Document 2 stops the energization of the heater during the drying operation, sucks the air in the space with the housing from the upper surface of the outer tub into the air blowing path, and all of the air discharged from the rotating drum. Or part of it is discharged from the drain hose to the drain. In addition, a method has been proposed in which water is supplied via a drain hose while ensuring the pressure of the drain hose after the end or end of the drying operation.
しかしながら，乾燥運転の最後又は終了後に排水ホースを経由して，排水トラップに水を供給する従来技術では，正常に運転が終了した場合には排水トラップに給水するため，排水ホースから排水トラップ下流の臭気が漂ってくるのを防止することが可能である。しかし，一時停止や電源ボタンなどが押下された場合や，何らかのエラーが発生して正常に終了できなかった場合は，排水トラップに給水されないために，臭気が漂ってくる場合が考えられる。また，脱水時に排水トラップが開放状態となった場合には，給水が行われない。 However, in the conventional technology that supplies water to the drain trap via the drain hose at the end or after the end of the drying operation, water is supplied to the drain trap when the operation ends normally. It is possible to prevent odors from drifting. However, if a temporary stop or power button is pressed, or if an error occurs and the process cannot be completed normally, the drain trap may not be filled and odors may drift. In addition, when the drain trap is opened during dehydration, water supply is not performed.
そこで，本発明では，水を溜める外槽と，前記外槽内に回転自在に配置され，洗濯物を収容する洗濯兼脱水槽と，この洗濯兼脱水槽を駆動するモータと，前記洗濯兼脱水槽を支持する筐体と，前記外槽から排出される水を排出する排水ホースと、前記外槽に給水するための給水手段と、を備え，乾燥運転が中断された場合に，前記給水手段を開くことで排水ホースから水を排出することを特徴とする。
Therefore, in the present invention, an outer tub for storing water, a washing / dehydrating tub that is rotatably disposed in the outer tub, and stores laundry, a motor that drives the washing / dehydrating tub, and the washing / demounting tub. comprising a housing for supporting the water tub, and a drain hose for discharging water discharged from the outer tub, and a water supply means for supplying water to the outer tub, when the drying operation is interrupted, the water supply means It is characterized by discharging water from the drainage hose by opening .
本発明によれば，一時停止を押下することなどにより運転が中断した状態で，電源ボタンが押下された場合や長時間運転が中断された場合においても，排水トラップに給水されるので，排水口から臭気が出てくるのを防止し，洗濯機または洗濯乾燥機内部やこれらが設置されている部屋の環境が悪化するのを防止することができる。 According to the present invention, the drain trap is supplied even when the power button is pressed or the operation is interrupted for a long time when the operation is interrupted by pressing a pause or the like. It is possible to prevent the odor from coming out and to prevent the environment inside the washing machine or the washing / drying machine and the room where these are installed from deteriorating.
（第１の実施形態例）
以下，本実施の形態例について図面を用いて説明する。
(First embodiment)
Hereinafter, this embodiment will be described with reference to the drawings.
図１は，本発明の第１の実施例に係るもので，洗濯乾燥機の斜視図を示す。ベース１の上部には鋼板と樹脂成形品で組合わされて構成された外枠２が載せられている。外枠２の正面には洗濯物３１を出し入れするドア３と前面カバー２ａ及び背面には背面カバー２ｂが設けられている。外枠２前方上部には，操作・表示パネル４を設けており，電源ボタン４ａ，スタート／一時停止ボタン４ｂ，コース選択ボタン４ｃなどの操作ボタンや残時間表示部４ｄなどの表示部を備えている。 FIG. 1 is a perspective view of a washing / drying machine according to a first embodiment of the present invention. On the upper part of the base 1, an outer frame 2 composed of a steel plate and a resin molded product is placed. A door 3 and a front cover 2a for taking in and out the laundry 31 are provided on the front surface of the outer frame 2, and a back cover 2b is provided on the back surface. An operation / display panel 4 is provided at the upper front of the outer frame 2 and includes operation buttons such as a power button 4a, a start / pause button 4b, a course selection button 4c, and a display section such as a remaining time display section 4d. Yes.
図２は，本発明の第１の実施例に係るもので，乾燥工程前半の洗濯乾燥機の断面図を示す。図３は，本発明の第１の実施例に係るもので，乾燥工程後半の洗濯乾燥機の断面図を示す。外枠２の内側には水を溜める外槽２０が備えられ，下部を左右一対のサスペンション２１により支持されている。外槽２０の内側にある洗濯兼脱水槽３０にはドア３を開けて投入された洗濯物３１があり，洗濯兼脱水槽３０の開口部の外周には脱水時の洗濯物３１のアンバランスによる振動を低減するための流体バランサー３２が設けられている。また，洗濯兼脱水槽３０の内側には洗濯物３１を掻き揚げる複数個のリフター３３が設けられている。洗濯兼脱水槽３０は，洗濯兼脱水槽用金属製フランジ３４に連結された主軸３５を介して，洗濯兼脱水槽駆動用モータ３６に直結されている。外槽２０の開口部には，ゴム製のパッキン２２が取付けられている。このパッキン２２は，外槽２０内とドア３との水密性を維持する役割をしている。これにより，洗い，すすぎ及び脱水時の水漏れの防止が図られている。洗濯兼脱水槽３０は，側壁に遠心脱水および通風用の多数の小孔（図示せず）を有する。外槽２０の底壁に開口した排水口２３は，排水弁２４を介して排水ホース９に接続する。 FIG. 2 relates to the first embodiment of the present invention, and shows a cross-sectional view of the washing and drying machine in the first half of the drying process. FIG. 3 relates to the first embodiment of the present invention, and shows a cross-sectional view of the washing / drying machine in the latter half of the drying process. An outer tub 20 for storing water is provided inside the outer frame 2, and the lower part is supported by a pair of left and right suspensions 21. The washing / dehydrating tub 30 inside the outer tub 20 has a laundry 31 that is loaded with the door 3 opened, and the outer periphery of the opening of the washing / dehydrating tub 30 is caused by an imbalance of the laundry 31 during dehydration. A fluid balancer 32 is provided for reducing vibration. A plurality of lifters 33 for lifting the laundry 31 are provided inside the washing / dehydrating tank 30. The washing / dehydrating tub 30 is directly connected to a washing / dehydrating tub drive motor 36 via a main shaft 35 connected to a metal flange 34 for the washing / dehydrating tub. A rubber packing 22 is attached to the opening of the outer tub 20. The packing 22 serves to maintain the water tightness between the inside of the outer tub 20 and the door 3. This prevents water leakage during washing, rinsing and dehydration. The washing and dewatering tub 30 has a large number of small holes (not shown) for centrifugal dewatering and ventilation on the side wall. A drain port 23 opened in the bottom wall of the outer tub 20 is connected to the drain hose 9 via a drain valve 24.
洗濯兼脱水槽３０内の洗濯物３１を乾燥させる除湿ダクト４０と，送風手段たるファン４１ａと加熱手段たるヒータ４１ｂを含む乾燥装置４１は，外枠２に固定（図示せず）されている。除湿ダクト４０と外槽２０の後方下部に設ける通風口４２は柔軟構造のベローズ４３を略水平に接続し，ヒータ４１ｂの出口と吹出しノズル４５は外槽２０の最上面から中心までの間で，且つ外槽２０の中心より前面の位置に柔軟構造のベローズ４４を用いて外槽２０に対し略垂直に接続して，外槽２０の振動を吸収している。 A drying device 41 including a dehumidifying duct 40 for drying the laundry 31 in the washing and dewatering tub 30, a fan 41 a serving as a blowing means and a heater 41 b serving as a heating means is fixed to the outer frame 2 (not shown). A ventilation port 42 provided in the lower rear portion of the dehumidifying duct 40 and the outer tub 20 connects the flexible bellows 43 substantially horizontally, and the outlet of the heater 41b and the blowing nozzle 45 are located between the uppermost surface and the center of the outer tub 20, In addition, the bellows 44 having a flexible structure is connected to the front of the outer tub 20 from the center of the outer tub 20 so as to be connected substantially perpendicular to the outer tub 20 to absorb the vibration of the outer tub 20.
このように構成したドラム式洗濯乾燥機は，洗濯工程においては，洗濯兼脱水槽３０内に洗濯物３１を投入し，排水弁２４を閉じた状態で給水して外槽２０に洗濯水を溜め，洗濯兼脱水槽３０を回転させて洗濯物３１を洗濯する。また，脱水工程においては，排水弁２４を開いて外槽２０内の洗濯水を排水し，洗濯兼脱水槽３０を回転させて遠心脱水する。そして，乾燥工程では，洗濯兼脱水槽３０を回転させながら吹出しノズル４５から空気を衣類に吹き付けることで衣類の乾燥を行う。乾燥工程前半では，循環式の乾燥を行う。吹出しノズル４５から洗濯兼脱水槽３０内の洗濯物３１に向けて吹出す循環空気４６は，外槽２０内の空気をファン４１ａを運転することで，通風口４２，除湿ダクト４０内を通過させて除湿し，ヒータ４１ｂで加熱して生成する。洗濯兼脱水槽３０内で洗濯物３１から水分を奪って高湿となった循環空気４６の除湿は，冷却水弁（図示せず）を開き冷却水供給管５１から除湿ダクト４０内に流れ出た冷却水５２を流下させ，循環空気４６と触れさせることによる水冷除湿で実現する。除湿ダクト４０内に流れ出た冷却水５２は排水口２３を通って排水ホース９により排出される。 The drum type washing and drying machine configured as described above stores the washing water in the outer tub 20 by putting the laundry 31 into the washing and dewatering tub 30 and supplying water with the drain valve 24 closed in the washing process. , The washing / dehydrating tank 30 is rotated to wash the laundry 31. In the dehydration step, the drain valve 24 is opened to drain the washing water in the outer tub 20, and the washing and dewatering tub 30 is rotated to perform centrifugal dehydration. In the drying process, the clothes are dried by blowing air from the blowing nozzle 45 to the clothes while rotating the washing and dewatering tank 30. In the first half of the drying process, circulation drying is performed. The circulating air 46 blown out from the blowing nozzle 45 toward the laundry 31 in the washing / dehydrating tub 30 allows the air in the outer tub 20 to pass through the ventilation port 42 and the dehumidifying duct 40 by operating the fan 41a. It is generated by dehumidifying and heating with the heater 41b. The dehumidification of the circulating air 46, which was dehumidified from the laundry 31 in the washing and dewatering tub 30 and became highly humid, opened a cooling water valve (not shown) and flowed from the cooling water supply pipe 51 into the dehumidifying duct 40. This is achieved by water-cooling dehumidification by causing the cooling water 52 to flow down and touching the circulating air 46. The cooling water 52 that has flowed into the dehumidifying duct 40 passes through the drain port 23 and is discharged by the drain hose 9.
図３に示す乾燥工程後半では，排気式乾燥を行うためヒータ４１ｂをＯＦＦにして冷却水５２を止める。そして，吸気弁４７を開くことによってベース１下部の隙間から吸込まれた外部空気４８は，外槽２０の側面を流れながら外槽２０，モータ３６，ファン４１ａの排熱を受けながら温められ，乾燥中盤までに外槽２０の上面と外枠２の空間に溜められた高温の筐体内部空気４９とともにファン４１ａへ吸込まれる。吸込まれた筐体内部空気４９は洗濯物３１に吹付けられ洗濯物３１から水分を奪い，湿潤して排水口２３より排水ホース９を通り，排水トラップ１０の水封を破って排水口３９に排出される。一般的な排水トラップの場合，水封の高さは５０〜８０mm程度あるため，水封を破るには排水ホース９側の圧力は約１０００Ｐａ以上必要となる。また，排水口３９からの臭気が本体内に漂ってこないようにするため，水封を破った後も高い圧力（所定以上の圧力）を維持する必要があり，排気式乾燥中はファン４１ａを制御して高い圧力を維持する。 In the latter half of the drying process shown in FIG. 3, the heater 41b is turned off to stop the cooling water 52 in order to perform exhaust-type drying. The external air 48 sucked from the gap at the bottom of the base 1 by opening the intake valve 47 is heated while receiving the exhaust heat of the outer tank 20, the motor 36, and the fan 41a while flowing through the side surface of the outer tank 20, and is dried. By the middle, the air is sucked into the fan 41a together with the high-temperature housing internal air 49 accumulated in the space of the upper surface of the outer tub 20 and the outer frame 2. The sucked interior air 49 is blown onto the laundry 31 to take moisture from the laundry 31, gets wet, passes through the drain hose 9 from the drain port 23, breaks the water seal of the drain trap 10, and enters the drain port 39. Discharged. In the case of a general drain trap, since the height of the water seal is about 50 to 80 mm, the pressure on the drain hose 9 side is required to be about 1000 Pa or more to break the water seal. Also, in order to prevent the odor from the drain 39 from drifting into the main body, it is necessary to maintain a high pressure (pressure above a predetermined level) even after breaking the water seal. Control to maintain high pressure.
乾燥終了後は，排水口３９側の圧力より排水ホース９側の排水トラップ１０下流の臭気が本体に漂うのよ抑制しつつ，水封を破らない圧力レベルまでファン４１ａの回転数を下げて，給水手段８０を開けて給水管８１に水を流し，排水ホース９を介して排水トラップ１０の水封を回復させて乾燥工程終了となる。このように，乾燥終了後に，排水ホース９側の圧力を所定以上に維持しながら排水ホース９を経由して排水口３９に水を供給することにより，排水口３９からの臭気を抑えながら排水トラップ１０の水封を回復させることができる。なお，この排水トラップの回復は，排水ホース９側の圧力が所定以上であれば，乾燥運転の最後又は乾燥運転の終了後のいずれでも良い。 After the drying is finished, the rotation speed of the fan 41a is lowered to a pressure level that does not break the water seal while suppressing the odor downstream of the drainage trap 10 on the drainage hose 9 side from drifting in the main body from the pressure on the drainage port 39 side. The water supply means 80 is opened, water is supplied to the water supply pipe 81, the water seal of the drain trap 10 is recovered via the drain hose 9, and the drying process ends. As described above, after the drying is completed, the drainage trap is performed while suppressing the odor from the drainage port 39 by supplying water to the drainage port 39 via the drainage hose 9 while maintaining the pressure on the drainage hose 9 side above a predetermined value. Ten water seals can be recovered. The drain trap can be recovered at the end of the drying operation or after the end of the drying operation as long as the pressure on the drain hose 9 side is equal to or higher than a predetermined value.
次に，排気式乾燥運転の制御を図４〜６に示すフローチャートを用いて説明する。図４および図５は排気式乾燥の制御を示すフローチャートであり，図６は排水トラップ１０への給水制御を示すフローチャートである。排気式乾燥を開始し，Ｓ１０１で圧力センサによる外槽２０内圧の計測を開始する。圧力の計測は，ダイヤフラムを用いた水位センサでもよい。Ｓ１０２で吸気弁４７を開け，吸気を開始する。Ｓ１０３で所定時間経過後の外槽２０内圧が所定値Ｐ１以上となったか判定し，Ｐ１以上の場合は，排水トラップ１０が接続されていると判定し，Ｓ１０４に進む。そして，Ｓ１０４で外槽２０の内圧が所定値Ｐ２よりも小さいか判定し，Ｐ２より小さい場合は排水トラップ１０の水を飛ばしたと判定し，Ｓ１０５で排水トラップ判定値Ｔに１を入れて排気式乾燥を継続する。ここで，Ｐ１はＰ２よりも小さい値とする。 Next, the control of the exhaust-type drying operation will be described using the flowcharts shown in FIGS. 4 and 5 are flowcharts showing the control of the exhaust type drying, and FIG. 6 is a flowchart showing the water supply control to the drain trap 10. Exhaust-type drying is started, and measurement of the inner pressure of the outer tub 20 by the pressure sensor is started in S101. The pressure may be measured by a water level sensor using a diaphragm. In S102, the intake valve 47 is opened and intake is started. In S103, it is determined whether the internal pressure of the outer tub 20 after a predetermined time has elapsed is equal to or greater than a predetermined value P1, and if it is equal to or greater than P1, it is determined that the drain trap 10 is connected, and the process proceeds to S104. Then, in S104, it is determined whether the internal pressure of the outer tub 20 is smaller than a predetermined value P2. If it is smaller than P2, it is determined that the water in the drain trap 10 has been blown, and in S105, 1 is set in the drain trap determination value T and the exhaust type Continue drying. Here, P1 is a value smaller than P2.
Ｓ１０３で外槽２０の内圧がＰ１以下の場合は，排水トラップ１０が接続されていないと判定し，Ｓ１０６で排水トラップ判定値Ｔを２として，乾燥運転を継続する。Ｓ１０４で外槽２０の内圧がＰ２より大きい場合は，ファン４１ａで排水トラップ１０の水封を破ることができないと判定し，Ｓ１０７で排水トラップ判定値Ｔに３を入れて，循環式乾燥に移行する。このように，排気式乾燥の初めに排水トラップ１０が接続されているか，排水トラップ１０の水封が破れているかを判定する。次に，図５に示す制御に移行する。 If the internal pressure of the outer tub 20 is equal to or lower than P1 in S103, it is determined that the drain trap 10 is not connected, the drain trap determination value T is set to 2 in S106, and the drying operation is continued. If the internal pressure of the outer tub 20 is greater than P2 in S104, it is determined that the water seal of the drain trap 10 cannot be broken by the fan 41a, and the drain trap determination value T is set to 3 in S107 and the process proceeds to circulation drying. To do. Thus, it is determined whether the drain trap 10 is connected at the beginning of the exhaust drying or whether the water seal of the drain trap 10 is broken. Next, the control shifts to the control shown in FIG.
Ｓ１０８で停電やコンセントを抜くなどして運転中に通電が遮断されたかどうか判定し，通電がされていればＳ１０９に進む。Ｓ１０９でスタート／一時停止ボタン４ｂが押下されたかどうかを判定し，押下されていない場合はＳ１１０に進む。Ｓ１１０で電源ボタン４ａが押下されたかどうかを判定し，押下されていな場合はＳ１１１に進み，Ｓ１１２で乾燥運転が終了したか判定し，終了していない場合は乾燥運転を継続し，運転が終了した場合はＳ１１２に進む。Ｓ１１３では，排水トラップ判定値Ｔが１であるか判定し，１の場合はＳ１１３に進み排水トラップ１０に給水し，Ｓ１１４でファン４１ａを停止する。ファン４１ａ停止後はＳ１１５で排水トラップ判定値Ｔに０を入れて，運転を終了する。 In S108, it is determined whether or not the energization is interrupted during operation by power failure or unplugging. If the energization is performed, the process proceeds to S109. In S109, it is determined whether the start / pause button 4b has been pressed. If not, the process proceeds to S110. In S110, it is determined whether or not the power button 4a has been pressed. If not, the process proceeds to S111. In S112, it is determined whether or not the drying operation has been completed. If not, the drying operation is continued and the operation is completed. If so, the process proceeds to S112. In S113, it is determined whether or not the drain trap determination value T is 1. If the drain trap determination value T is 1, the process proceeds to S113 to supply water to the drain trap 10, and the fan 41a is stopped in S114. After the fan 41a is stopped, the drain trap determination value T is set to 0 in S115 and the operation is terminated.
Ｓ１１２で排水トラップ判定値Ｔが１以外の場合は，排水トラップ１０への給水の必要がないと判定し，Ｓ１１４でファンを停止し，Ｓ１１５で排水トラップ判定値Ｔに０を入れて，運転を終了する。 If the drain trap determination value T is other than 1 in S112, it is determined that there is no need to supply water to the drain trap 10, the fan is stopped in S114, 0 is entered in the drain trap determination value T in S115, and the operation is started. finish.
Ｓ１１０で電源ボタン４ａが押下された場合には，Ｓ１１２に進む。 If the power button 4a is pressed in S110, the process proceeds to S112.
Ｓ１０９でスタート／一時停止ボタン４ｂが押下された場合にはＳ１１６に進む。スタート／一時停止ボタン４ｂが押下されＳ１１６に進んだ場合は，所定時間内にスタート／一時停止ボタン４ｂが押下されたか判定し，押下された場合はＳ１０８に戻り運転を継続する。そして，所定時間内にスタート／一時停止ボタン４ｂが押下されなかった場合は，Ｓ１１２に進む。 If the start / pause button 4b is pressed in S109, the process proceeds to S116. If the start / pause button 4b is pressed and the process proceeds to S116, it is determined whether the start / pause button 4b is pressed within a predetermined time. If the start / pause button 4b is pressed, the process returns to S108 to continue the operation. If the start / pause button 4b is not pressed within the predetermined time, the process proceeds to S112.
また，Ｓ１０８で停電などによって通電が遮断されたと判断した場合，通電回復後にＳ１１７でオートリスタート機能を有しているか判定する。オートリスタート機能は，通電が遮断された時の状態を記録し，通電回復時に自動で中断時の状態から継続して運転を開始する機能である。オートリスタート機能を有する場合は，中断前の状態から運転を継続する。オートリスタート機能を有しない場合は，Ｓ１１８で排水トラップ判定値Ｔが３であるか判定し，１の場合はＳ１１９で排水トラップ１０に給水し，Ｓ１２０でファン４１ａを停止し，待機する。Ｓ２１０で排水トラップ判定値Ｔが１以外の場合は，排水トラップ１０への給水を行わずに，待機する。 If it is determined in S108 that the energization has been cut off due to a power failure or the like, it is determined in S117 whether the auto restart function is provided after the energization is restored. The auto-restart function is a function that records the state when the power is cut off and automatically starts operation from the interrupted state when power is restored. If it has an auto-restart function, continue operation from the state before the interruption. If the auto-restart function is not provided, it is determined whether or not the drain trap determination value T is 3 in S118. If it is 1, water is supplied to the drain trap 10 in S119, and the fan 41a is stopped and waits in S120. If the drain trap determination value T is other than 1 in S210, the system waits without supplying water to the drain trap 10.
次に，Ｓ１１４やＳ１１９などで行う排水トラップ１０への給水方法について述べる。まず，Ｓ２０１でファン４１ａを低速モードで運転し，給水手段８０を開けて，排水トラップ１０に給水する。Ｓ２０２で所定時間経過したか判定し，経過していない場合はＳ２０３で水位センサの値が所定の圧力以上かどうか判定し，所定の圧力以下の場合はＳ２０２に戻る。所定の圧力以上の場合は，排水トラップ１０の水封が完了したと判断し，Ｓ２０４で給水手段８０を閉じて給水工程を終了する。また，Ｓ２０２で所定時間が経過したと判定した場合は，Ｓ２０４に進み，給水手段８０を閉じて給水工程を終了してもよい。 Next, a method for supplying water to the drain trap 10 performed in S114 and S119 will be described. First, in S201, the fan 41a is operated in the low speed mode, the water supply means 80 is opened, and water is supplied to the drain trap 10. In S202, it is determined whether a predetermined time has elapsed. If not, it is determined in S203 whether the value of the water level sensor is equal to or higher than a predetermined pressure, and if it is lower than the predetermined pressure, the process returns to S202. If the pressure is equal to or higher than the predetermined pressure, it is determined that the water sealing of the drain trap 10 has been completed, the water supply means 80 is closed in S204, and the water supply process ends. If it is determined in S202 that the predetermined time has elapsed, the process proceeds to S204, where the water supply means 80 may be closed to end the water supply process.
本実施例では，運転終了時や運転停止時に給水工程を行う際に，ファン４１ａを駆動し，排水トラップ１０から臭気が上がってくるのを抑制しているが，排水トラップ１０に給水する時間は短いため，必ずしもファン４１ａを駆動する必要はない。 In this embodiment, when the water supply process is performed at the end of operation or when the operation is stopped, the fan 41a is driven to suppress the odor from rising from the drain trap 10, but the time for supplying water to the drain trap 10 is as follows. Since it is short, it is not always necessary to drive the fan 41a.
また，排水ホース９から排水トラップ１０に給水するために，給水管８１を設けて直接排水ホース９に給水する方法について述べたが，必ずしも専用の給水経路を有する必要はなく，乾燥運転時に使用する冷却水や外槽２０内の泡を消すための水が流れる経路など衣類に水が当たらない給水方法を使用してもよい。 Moreover, in order to supply water from the drainage hose 9 to the drainage trap 10, the method of providing the water supply pipe 81 and supplying water directly to the drainage hose 9 has been described, but it is not always necessary to have a dedicated water supply path, and it is used during drying operation. You may use the water supply method which water does not contact clothing, such as the path | route through which the water for extinguishing the cooling water and the bubble in the outer tank 20 flows.
前述のように，電源ボタン４ａが押下された場合には，その時点で排水トラップ１０へ給水する。これにより，運転が中断された場合においても，排水トラップ１０が開放されたままとなることを防止することができ，本体内や洗濯乾燥機を設置している部屋に臭気が漂う量を最小限に抑えることが可能となる。また，電源ボタン４ａ押下後においても，給水中は操作・表示パネル４に給水中であることを示すことが望ましい。これにより，電源ボタン４ａ押下後に，給水による水の音が生じても，使用者が誤って本体の故障と判断することを防止する。操作・表示パネル４への表示は，任意のランプを点灯，または点滅でもよい。 As described above, when the power button 4a is pressed, water is supplied to the drain trap 10 at that time. As a result, even when the operation is interrupted, it is possible to prevent the drain trap 10 from being left open, and to minimize the amount of odor drifting in the body or the room where the washing dryer is installed. It becomes possible to suppress to. Even after the power button 4a is pressed, it is desirable to indicate that the operation / display panel 4 is supplying water during water supply. This prevents the user from mistakenly determining that the main body has failed even if the sound of water due to water supply occurs after the power button 4a is pressed. For display on the operation / display panel 4, an arbitrary lamp may be lit or blinked.
一方，スタート／一時停止ボタン４ｂが押下された場合には，使用者が衣類の取り出しを行った後，再スタートする可能性があるため，電源ボタン４ａを押下した場合と異なり，図５のＳ１１６に示す判定のようにすぐには給水せずに，所定時間経過後に給水する方が望ましい。これにより，不必要な排水トラップ１０への給水や，排水トラップ１０を破る動作を繰り返さないため，使用水量の増加を抑制することができる。 On the other hand, when the start / pause button 4b is pressed, there is a possibility that the user may restart after taking out the clothes. Therefore, unlike the case where the user presses the power button 4a, S116 in FIG. It is preferable to supply water after a lapse of a predetermined time instead of supplying water immediately as in the determination shown in. Thereby, since the water supply to the unnecessary drain trap 10 and the operation | movement which breaks the drain trap 10 are not repeated, the increase in the amount of water used can be suppressed.
また，停電が発生した場合やコンセントが抜けた場合は，給水手段８０を開けることができないため，排水トラップ１０が開放されたままとなる。ここで，オートリスタート機能を有する場合は，通電回復時に中断された工程から運転を再開する。オートリスタート機能を有しない場合は，排水トラップ１０が開放されている状態かどうかを記録する手段を設け，通電が復帰した際に，排水トラップ１０が開放状態（排水トラップ判定値Ｔ＝１）と記録されていた場合には，排水トラップ１０へ給水する。これにより，停電時等においても，排水トラップ１０が開放状態となっている時間を短くすることができる。そして，記録手段に記録する情報は，停電やコンセントが抜けた場合などによって運転中に通電がなくなった工程でもよい。工程を記録する場合は，図７に示すような状態検知をしてもよい。Ｓ３０１で外槽２０の内圧を測定し，Ｐc以下の場合は外槽２０に水が溜められていないと判定し，Ｓ３０２でファン４０ａを駆動する。Ｓ３０３で排水トラップ１０が接続されているか判定するために，外槽２０の内圧を測定しＰ１以上の場合は，排水トラップ１０が接続されていると判定し，Ｓ３０４に進む。Ｓ３０４では外槽２０の内圧がＰ２以下であるか判定し，Ｐ２以下の場合は排水トラップ１０に十分な水がないと判定し，Ｓ３０５で排水トラップ１０に給水して，待機する。 In addition, when a power failure occurs or the outlet is disconnected, the water supply means 80 cannot be opened, and the drain trap 10 remains open. Here, when the auto-restart function is provided, the operation is resumed from the process interrupted when the power is restored. If the auto-restart function is not provided, a means for recording whether or not the drain trap 10 is open is provided, and when the energization is restored, the drain trap 10 is in the open state (drain trap determination value T = 1). If it has been recorded, water is supplied to the drain trap 10. Thereby, it is possible to shorten the time during which the drain trap 10 is in an open state even during a power failure. The information to be recorded in the recording means may be a process in which power is lost during operation due to a power failure or when an outlet is disconnected. When the process is recorded, the state detection as shown in FIG. 7 may be performed. In S301, the internal pressure of the outer tub 20 is measured. If the pressure is equal to or lower than Pc , it is determined that water is not accumulated in the outer tub 20, and the fan 40a is driven in S302. In order to determine whether or not the drain trap 10 is connected in S303, the internal pressure of the outer tub 20 is measured, and if it is P1 or more, it is determined that the drain trap 10 is connected and the process proceeds to S304. In S304, it is determined whether the internal pressure of the outer tub 20 is P2 or less. If P2 or less, it is determined that there is not enough water in the drain trap 10, and in S305, the drain trap 10 is supplied with water and waits.
Ｓ３０１で外槽２０の内圧がＰ３以上の場合は外槽２０内に水があるとして，排水トラップ１０に給水せずに待機する。Ｓ３０３で外槽２０の内圧がＰ１以下である場合は排水トラップ１０が接続されていないと判定し，給水を行わずに待機する。Ｓ３０４で外槽の内圧がＰ２以上の場合は，排水トラップ１０に水が十分に入っていると判定し，給水を行わずに待機する。 If the internal pressure of the outer tub 20 is P3 or higher in S301, it is assumed that there is water in the outer tub 20, and the standby is performed without supplying water to the drain trap 10. If the internal pressure of the outer tub 20 is equal to or lower than P1 in S303, it is determined that the drain trap 10 is not connected, and the process waits without supplying water. When the internal pressure of the outer tub is P2 or more in S304, it is determined that water is sufficiently contained in the drain trap 10, and the process waits without supplying water.
本実施例では，吸気手段を有する洗濯乾燥機について述べたが，必ずしも吸気手段を有する必要はない。外槽２０を含む循環風路内を完全に密閉することは困難であるため，ファン４１ａを駆動することにより，負圧となった部分から空気を吸い込む場合がある。その場合において，フィルタの目詰まりなどにより，空気の循環が阻害されると，外槽２０内の圧力が増加し，排水トラップ１０内の水を押し出し，水がなくなることがある。このような場合においても，スタート／一時停止ボタン４ｂや電源ボタン４ａが押下された場合には，排水トラップ１０に給水し，臭気が漂うを防止することができる。なお，外槽２０内の圧力を検知し，運転中に圧力が急に減少した場合には，排水トラップ１０の水が抜けたと判断し，その場合のみ運転が中断した際に注水することで，不必要な水を使用することがなくなる。 In the present embodiment, the washing / drying machine having the air intake means has been described, but it is not always necessary to have the air intake means. Since it is difficult to completely seal the circulation air passage including the outer tub 20, there is a case where air is sucked in from a negative pressure portion by driving the fan 41 a. In that case, if the circulation of air is hindered due to clogging of the filter, the pressure in the outer tub 20 increases, pushing out the water in the drain trap 10 and the water may be lost. Even in such a case, when the start / pause button 4b or the power button 4a is pressed, the drain trap 10 can be supplied with water to prevent odors from drifting. In addition, when the pressure in the outer tub 20 is detected and the pressure suddenly decreases during operation, it is determined that the water in the drain trap 10 has drained, and only when that operation is interrupted, Unnecessary water is not used.
前述のような制御を行うことで，防水パンに付随する排水トラップの場合には，部屋に漂う臭気も抑制することができる。 By performing the control as described above, in the case of the drain trap attached to the waterproof pan, the odor drifting in the room can be suppressed.
（第２の実施形態例）
図８は本発明の第２の実施例に係わるもので，洗濯乾燥機の内部構造を示す断面図である。第１の実施例と共通する構成については重複する説明を省略する。
(Second Embodiment)
FIG. 8 relates to the second embodiment of the present invention and is a cross-sectional view showing the internal structure of the washing / drying machine. A duplicate description of the configuration common to the first embodiment is omitted.
第１の実施例と異なるのは，排水経路を兼ねる貯水手段１０１の排水弁１０２の下流に，貯水タンク１０３，貯水タンク１０３に水を溜めるための貯水弁１０４，貯水タンク１０３と排水弁１０２の間にオーバーフロー管１０５を設ける点である。貯水タンク１０３は排水ホース９を介して排水トラップ１０に水が溜まる量を溜めることができる構造とし，貯水弁１０４は通電時のみ閉じる構造とする。排水トラップ１０に水を溜めるために必要な水量は，例えば，排水ホース９を含む排水経路の長さが２〜４ｍ，管の径が３０〜４０ｍｍ程度とすると，２Lから４L程度となる。 The difference from the first embodiment is that the water storage tank 103, the water storage valve 104 for storing water in the water storage tank 103, the water storage tank 103 and the water discharge valve 102 are arranged downstream of the water discharge valve 102 of the water storage means 101 that also serves as a water discharge path. The overflow pipe 105 is provided between them. The water storage tank 103 has a structure capable of storing the amount of water stored in the drain trap 10 through the drain hose 9, and the water storage valve 104 is closed only when energized. The amount of water necessary for accumulating water in the drain trap 10 is about 2L to 4L, for example, when the length of the drainage path including the drainage hose 9 is 2 to 4 m and the diameter of the pipe is about 30 to 40 mm.
次に排水弁１０２と貯水弁１０４の動作について説明する。洗い運転時には，排水弁１０２を閉じ，外槽２０内に水を溜める。脱水時には貯水弁１０４を閉じた状態で，排水弁１０２を開けて排水する。貯水弁１０４は閉じられているため貯水タンク１０３に所定の水量が溜められ，所定以上となった場合はオーバーフロー管１０５から排水ホース９に流れる。乾燥工程前半では，排水弁１０２を開放し，貯水弁１０４は閉じた状態とする。乾燥運転後半では，排水弁１０２を開放して衣類から蒸発した水を含む湿度の高い空気を，オーバーフロー管１０５，排水ホースを介して排水トラップ１０に排出する。運転終了時や電源ボタンの押下など排水トラップ１０への給水が必要となった場合には，貯水弁１０４を開放し，貯水タンク１０３に溜めた水を排水トラップ１０に給水する。 Next, operations of the drain valve 102 and the water storage valve 104 will be described. During the washing operation, the drain valve 102 is closed and water is accumulated in the outer tub 20. At the time of dehydration, the drainage valve 102 is opened and drained with the water storage valve 104 closed. Since the water storage valve 104 is closed, a predetermined amount of water is stored in the water storage tank 103, and when it exceeds a predetermined value, it flows from the overflow pipe 105 to the drain hose 9. In the first half of the drying process, the drain valve 102 is opened and the water storage valve 104 is closed. In the latter half of the drying operation, the drain valve 102 is opened, and high-humidity air containing water evaporated from clothing is discharged to the drain trap 10 through the overflow pipe 105 and drain hose. When it is necessary to supply water to the drain trap 10 at the end of the operation or when the power button is pressed, the water storage valve 104 is opened, and the water stored in the water storage tank 103 is supplied to the drain trap 10.
このように，洗濯やすすぎで使用した水や，脱水時に衣類から出た水を，排水トラップ１０を水封するために用いることができるため，使用水量の増加を抑制することができる。さらに，貯水弁１０４は通電された状態のみ弁が閉じる構造としておけば，停電などによって通電が途絶えた場合に自動的に排水トラップ１０に給水することができ，排水トラップ１０が開放されている時間を短くすることができ，排水口からの臭気が漂うのを防止することができる。 Thus, since the water used for washing and rinsing and the water discharged from the clothing during dehydration can be used to seal the drain trap 10, an increase in the amount of water used can be suppressed. Further, if the water storage valve 104 is configured to close only when it is energized, it can automatically supply water to the drain trap 10 when the energization is interrupted due to a power failure or the like, and the time when the drain trap 10 is open. Can be shortened, and the odor from the drain can be prevented from drifting.
ここで，乾燥工程前半で，排水弁１０２を開けて運転する方法を述べたが，必ずしも開けて運転する必要はなく，常時閉じても，開閉を交互に行ってもよい。ただし，乾燥工程前半で，水冷除湿ではなく空冷除湿を行う場合は，排水弁１０２を閉じた方が貯水タンク１０３内の水が高温の空気に触れることがなく，排水する水に余分な熱を与えないため，乾燥運転時の消費電力量を増加させずに運転することが可能である。 Here, the method of operating with the drain valve 102 opened in the first half of the drying process has been described, but it is not always necessary to operate with the drain valve open, and it may be always closed or alternately opened and closed. However, when air-cooled dehumidification is performed instead of water-cooled dehumidification in the first half of the drying process, when the drain valve 102 is closed, the water in the water storage tank 103 does not come into contact with high-temperature air, and excess heat is applied to the drained water. Therefore, it is possible to operate without increasing the power consumption during the drying operation.
また，貯水タンク１０３は外槽２０に設置してもよい。脱水時の外槽２０の振動は質量が大きいほど小さくなるため，脱水時に貯水タンク１０３内に水を満たすことで，外槽２０の質量が増加するので，振動を低減することができる。 Further, the water storage tank 103 may be installed in the outer tub 20. Since the vibration of the outer tub 20 at the time of dehydration decreases as the mass increases, filling the water storage tank 103 with water at the time of dehydration increases the mass of the outer tub 20, so that the vibration can be reduced.
また，貯水手段は図９に示すように，貯水タンクに給水管８１を介して給水手段８０を接続し，貯水タンク１１３から貯水弁１１４を介して排水ホース９に接続する構成でもよい。これにより，きれいな水を貯水タンク１１３に溜めることができるため，排水を溜める場合より貯水タンク１１３内を清潔に保つことができる。 Further, as shown in FIG. 9, the water storage means may be configured such that the water supply means 80 is connected to the water storage tank via the water supply pipe 81, and the water storage tank 113 is connected to the drain hose 9 via the water storage valve 114. Thereby, since clean water can be stored in the water storage tank 113, the inside of the water storage tank 113 can be kept clean compared with the case where waste water is stored.
さらに，貯水手段は図１０に示すように，貯水タンク１２３を除湿ダクト４０に接続し，貯水タンク１２３から貯水弁１２４を介して排水ホース９に接続する構成でもよい。これにより，高温の空気と熱交換することで温度が上昇した冷却水５２を貯水タンク１２３内に溜めるため，乾燥工程後半に行う排気式乾燥時に乾燥経路に取り入れる外部空気４８が貯水タンク１２３周辺を通過する際に温度が上昇し，消費電力量を低減することが可能になる。また，洗濯やすすぎで使用した水が貯水タンク１２３に入らないため，貯水タンク１２３内をより清潔に保つことができる。 Further, as shown in FIG. 10, the water storage means may be configured such that the water storage tank 123 is connected to the dehumidification duct 40, and the water storage tank 123 is connected to the drain hose 9 via the water storage valve 124. As a result, the cooling water 52 whose temperature has been raised by exchanging heat with high-temperature air is stored in the water storage tank 123, so that the external air 48 taken into the drying path during the exhaust-type drying that is performed in the latter half of the drying process is located around the water storage tank 123. As the temperature passes, the temperature rises and the power consumption can be reduced. Further, since the water used for washing and washing does not enter the water storage tank 123, the inside of the water storage tank 123 can be kept clean.
（第３の実施形態例）
脱水時の水封制御について述べる。脱水運転時に外槽２０が共振し，外槽２０の振動が大きくなると，外槽２０と外枠２を接続するゴム製のパッキン２２が伸縮するため，外槽２０内の圧力が変化する。例えば，前後方向の共振が発生する回転数は３００〜４００ｒ／ｍｉｎ程度である。外槽２０を含む循環風路の密閉性が高い場合，振動による圧力変動で排水トラップ１０の水が抜ける場合がある。そこで，振動検知手段によって外槽２０の振動が所定の値以上と判定した場合に排水トラップ１０に給水することで，脱水時においても，排水トラップ１０が開放状態となり，臭気が本体内に漂ってくるのを防止することができる。
(Third embodiment)
The water seal control during dehydration is described. When the outer tub 20 resonates during the dehydration operation and the vibration of the outer tub 20 increases, the rubber packing 22 that connects the outer tub 20 and the outer frame 2 expands and contracts, so that the pressure in the outer tub 20 changes. For example, the rotational speed at which the longitudinal resonance occurs is about 300 to 400 r / min. When the airtightness of the circulation air passage including the outer tub 20 is high, water in the drainage trap 10 may escape due to pressure fluctuation due to vibration. Therefore, by supplying water to the drain trap 10 when the vibration detection means determines that the vibration of the outer tub 20 is equal to or greater than a predetermined value, the drain trap 10 is opened even during dehydration, and odor drifts in the main body. It can be prevented from coming.
図１１に本実施例の制御方法を示すフローを示す。脱水運転を開始し，Ｓ４０１で洗濯兼脱水槽３０の回転速度を上昇させる。Ｓ４０２で振動検知１を行い，振動が大きいと判断した場合にはＳ４０３に進み，洗濯兼脱水槽３０の回転を停止し，再起動する。そして，振動が小さい場合にはＳ４０４に進み，振動検知２を行い，センサ出力が所定の値以下の場合は，脱水運転を継続する。そして，振動検知２で振動が大きいと判断した場合には，Ｓ４０５で給水判定値Ｗを１とし，Ｓ４０６に進み，設定した脱水時間を経過したか判定し，経過していればＳ４０７で洗濯兼脱水槽３０の回転を停止する。Ｓ４０８で給水判定値Ｗが０の場合は，排水トラップ１０への給水の必要がないため，そのまま運転を終了する。給水判定値Ｗが０以外の場合は，給水する必要があるためＳ４０９で排水トラップ１０に給水し，運転を終了する。このような制御を行うことで，脱水時に排水トラップ１０の水が減少した場合においても，給水することができ，臭気を防止することができる。 FIG. 11 shows a flow showing the control method of this embodiment. The dehydration operation is started, and the rotation speed of the washing and dewatering tank 30 is increased in S401. Vibration detection 1 is performed in S402, and if it is determined that the vibration is large, the process proceeds to S403, where the rotation of the washing and dewatering tub 30 is stopped and restarted. If the vibration is small, the process proceeds to S404 and vibration detection 2 is performed. If the sensor output is equal to or less than a predetermined value, the dehydration operation is continued. If the vibration detection 2 determines that the vibration is large, the water supply determination value W is set to 1 in S405, the process proceeds to S406, and it is determined whether the set dehydration time has elapsed. The rotation of the dewatering tank 30 is stopped. If the water supply determination value W is 0 in S408, there is no need to supply water to the drain trap 10, so the operation is terminated as it is. If the water supply determination value W is other than 0, it is necessary to supply water, so the water trap 10 is supplied with water in S409 and the operation is terminated. By performing such control, even when the water in the drain trap 10 decreases during dehydration, water can be supplied and odor can be prevented.
排水ホース９から排出する水は，実施例１に示すように専用の給水経路を設けてもよい。しかし，この場合には排水トラップ１０を塞ぐための水が余分に必要になる。そこで，脱水運転時に排水弁２４を閉じ，脱水終了時や運転中断時に排水弁２４を開けることで，外槽２０や排水経路に溜まった水を排水ホース９から排水トラップ１０に排出してもよい。このような制御を行うことで，水の使用量を抑えることができる。 The water discharged from the drain hose 9 may be provided with a dedicated water supply path as shown in the first embodiment. However, in this case, extra water for closing the drain trap 10 is required. Therefore, the water accumulated in the outer tub 20 or the drainage path may be discharged from the drainage hose 9 to the drainage trap 10 by closing the drainage valve 24 during the dehydration operation and opening the drainage valve 24 at the end of the dehydration or when the operation is interrupted. . By performing such control, the amount of water used can be reduced.
また，高速で脱水する際にも排水トラップ１０の水が抜ける場合があるため，前述のように排水弁２４を閉じて溜めた水は，脱水終了時に排水トラップ１０に給水する方が望ましい。脱水中に圧力センサで外槽２０の内圧を測定し，所定の圧力以下で合った場合に限り，排水トラップ１０への給水を行ってもよい。 In addition, since the water in the drain trap 10 may be drained even when dewatering at high speed, it is desirable to supply the water collected by closing the drain valve 24 to the drain trap 10 at the end of the dehydration as described above. The water pressure to the drain trap 10 may be supplied only when the internal pressure of the outer tub 20 is measured with a pressure sensor during dehydration and the pressure is below a predetermined pressure.
さらに，本実施例では，洗濯兼脱水槽３０の回転が停止した後に排水トラップ１０への給水を行う方法を説明したが，給水による運転時間の延長を短くするために，洗濯兼脱水槽３０の回転速度を低下させる過程で排水トラップ１０への給水を行ってもよい。 Furthermore, in the present embodiment, the method of supplying water to the drain trap 10 after the rotation of the washing and dewatering tub 30 is stopped has been described. However, in order to shorten the extension of the operation time due to water supply, Water supply to the drain trap 10 may be performed in the process of reducing the rotation speed.
（第４の実施形態例）
図１２，図１３は本発明の第４の実施例に係わるもので，空気の加熱・除湿手段としてヒートポンプを採用した場合の一例である。第１の実施例と共通する構成については重複する説明を省略する。
(Fourth embodiment)
FIGS. 12 and 13 relate to a fourth embodiment of the present invention, and are an example in which a heat pump is employed as air heating / dehumidifying means. A duplicate description of the configuration common to the first embodiment is omitted.
洗濯物３１の乾燥時に用いる温風の熱源には，凝縮器５５と湿った空気を除湿する蒸発器５８を内蔵するヒートポンプ５０を使用している。ヒートポンプ５０は，図１２に示すように外槽２０の後方下部に配置し，圧縮機５４，凝縮器５５，膨張機構５７，蒸発器５８から主に構成されており，冷媒の流れは以下のようになる。圧縮機５４で圧縮された高温高圧ガスを凝縮器５５にて空気と熱交換させる。その後膨張機構５７で減圧させた冷媒を蒸発器５８にて蒸発させて，低圧ガスを圧縮機５４に戻す。 As a heat source for warm air used when the laundry 31 is dried, a heat pump 50 including a condenser 55 and an evaporator 58 for dehumidifying damp air is used. As shown in FIG. 12, the heat pump 50 is disposed in the lower rear portion of the outer tub 20 and mainly includes a compressor 54, a condenser 55, an expansion mechanism 57, and an evaporator 58. The refrigerant flow is as follows. become. The high-temperature and high-pressure gas compressed by the compressor 54 is heat-exchanged with air by the condenser 55. Thereafter, the refrigerant decompressed by the expansion mechanism 57 is evaporated by the evaporator 58, and the low-pressure gas is returned to the compressor 54.
通常の乾燥運転時の空気の流れは次のようになる。ファン５９を運転し，ヒートポンプの圧縮機５４を運転することにより凝縮器５５が発熱し，吹出し口１４０ａから洗濯兼脱水槽３０の背面の貫通孔より洗濯兼脱水槽３０内に高速の温風が吹込む（矢印１４１）。温風は湿った洗濯物３１に当たり，洗濯物３１を温めて，洗濯物３１の水分を蒸発させる。高温多湿となった空気は，吸気口１４２からダクト１４０へ入る。ダクト１４０に設けたフィルタ１４３を通り糸屑が取除かれ，蒸発器５８へ入る。高温多湿の空気は低温の蒸発器５８と接触することで冷却除湿され，乾いた低温空気となり，高温の凝縮器５５で再度加熱されファン５９に吸込まれる。そして，ダクト１４０を通って洗濯兼脱水槽３０内に吹込むように循環する。 The flow of air during normal drying operation is as follows. By operating the fan 59 and the compressor 54 of the heat pump, the condenser 55 generates heat, and high-speed hot air is blown into the washing / dehydrating tub 30 from the outlet 140a through the through-hole on the back of the washing / dehydrating tub 30. Inject (arrow 141). The warm air hits the wet laundry 31, warms the laundry 31, and evaporates the moisture in the laundry 31. The air that has become hot and humid enters the duct 140 through the air inlet 142. The lint is removed through the filter 143 provided in the duct 140 and enters the evaporator 58. The hot and humid air is cooled and dehumidified by coming into contact with the low temperature evaporator 58, becomes dry low temperature air, is heated again by the high temperature condenser 55, and is sucked into the fan 59. Then, it circulates through the duct 140 so as to be blown into the washing / dehydrating tub 30.
蒸発器５８で高温多湿の空気から取り除かれた水は，蒸発器５８の下部に設けられた貯水部７０に流れる。貯水部７０は下流側に貯水弁７１を備え，貯水部７０の所定の高さには，オーバーフロー経路７２を有する。運転中は貯水弁７１を閉じ，貯水部７０に水を溜める。貯水部７０はオーバーフロー経路７２を有するため，水量が所定以上となった場合には，オーバーフロー経路７２から排水ホース９へ水が流れる。 The water removed from the hot and humid air by the evaporator 58 flows into the water storage unit 70 provided at the lower part of the evaporator 58. The water storage unit 70 includes a water storage valve 71 on the downstream side, and has an overflow path 72 at a predetermined height of the water storage unit 70. During operation, the water storage valve 71 is closed and water is stored in the water storage unit 70. Since the water reservoir 70 has the overflow path 72, when the amount of water exceeds a predetermined level, water flows from the overflow path 72 to the drain hose 9.
乾燥工程後半では，ヒートポンプ５０の圧縮機５４を停止する。そして，吸気弁１４７を開くことによりベース１下部の隙間から吸込まれた外部空気４８は，外槽２０の側面を流れながら外槽２０，モータ３６，圧縮機５４，貯水部７０の排熱を受けながら温められ，ダクト１４０へ吸込まれる。吸込まれた空気はヒートポンプ５０を通り吹出し口１４０ａから洗濯物３１に吹付けられ洗濯物３１から水分を奪い，湿潤して排水口２３より排水ホース９を通り，排水トラップ１０の水封を破って排水口３９に排出される。 In the latter half of the drying process, the compressor 54 of the heat pump 50 is stopped. The external air 48 sucked from the gap at the bottom of the base 1 by opening the intake valve 147 receives exhaust heat from the outer tub 20, the motor 36, the compressor 54, and the water storage section 70 while flowing through the side surface of the outer tub 20. While being warmed, it is sucked into the duct 140. The sucked air passes through the heat pump 50 and is blown to the laundry 31 from the outlet 140a, deprives the laundry 31 of moisture, gets wet, passes through the drain hose 9 from the drain port 23, breaks the water seal of the drain trap 10 It is discharged to the drain port 39.
乾燥工程終了後は，排水トラップ１０の下流から臭気が本体内に漂わないように排水口３９側の圧力より排水ホース９側の圧力を高く保ちつつ，排水トラップ１０の水封を破らない圧力レベルまでファン５９の回転数を下げる。貯水弁７３を開放して貯水部７０内の水を，排水ホース９を介して排水トラップ１０に給水して乾燥終了となる。 After the drying process, the pressure level that does not break the water seal of the drain trap 10 while keeping the pressure on the drain hose 9 side higher than the pressure on the drain port 39 side so that odors do not drift from the downstream of the drain trap 10 into the main body. The rotational speed of the fan 59 is decreased until The water storage valve 73 is opened and the water in the water storage section 70 is supplied to the drain trap 10 via the drain hose 9 to complete the drying.
スタート／一時停止ボタン４ｂや電源ボタン４ａが押下された場合も運転終了時同様に，ファン５９の風量が低下した場合には，貯水弁７１を開放し，排水ホース９を介して，排水トラップ１０に給水する。このように，高温多湿の空気から除湿した水を使って，排水トラップを水封することで水の使用量が増加するのを抑制することができる。貯水部７０の水量を検出する水位センサを設けることで，除湿した水が少ない場合には，給水手段８０から給水管８１を介して排水ホース９に給水し，排水トラップ１０を水封する。 Even when the start / pause button 4b or the power button 4a is pressed, the storage valve 71 is opened and the drain trap 10 is opened via the drain hose 9 when the air volume of the fan 59 decreases, as in the end of the operation. Supply water. Thus, it is possible to suppress an increase in the amount of water used by sealing the drain trap using water dehumidified from high-temperature and high-humidity air. By providing a water level sensor for detecting the amount of water in the water storage unit 70, when the dehumidified water is small, water is supplied from the water supply means 80 to the drain hose 9 via the water supply pipe 81, and the drain trap 10 is sealed.
本実施例ではオーバーフロー経路７２を設けたが，貯水部７０に十分な容積を確保できれば，必ずしもオーバーフロー経路７２を設ける必要はない。 Although the overflow path 72 is provided in the present embodiment, the overflow path 72 is not necessarily provided if a sufficient volume can be secured in the water storage unit 70.
