Description

本発明は、衣類等の乾燥を行う衣類乾燥機に関するものである。 The present invention relates to a clothes dryer for drying clothes and the like.

従来、この種の衣類乾燥機は、ヒートポンプ装置を用いて衣類等を乾燥させることが提案されている。乾燥風が循環する循環風路にヒートポンプ装置の蒸発器と凝縮器を近接して設け、コンパクトに構成されるのが一般的である（例えば、特許文献１参照）。 Conventionally, this type of clothes dryer has been proposed to dry clothes and the like using a heat pump device. In general, an evaporator and a condenser of a heat pump device are provided close to a circulation air passage through which dry air circulates, and is configured compactly (see, for example, Patent Document 1).

図１１は、特許文献１に記載された従来の衣類乾燥機の要部の構成を示すものである。図１１に示すように、ヒートポンプ装置５１の循環風路５２に蒸発器５３と凝縮器５４を近接して設け、蒸発器５３の重力方向端である下端５３ａを、凝縮器５４の重力方向端である下端５４ａより重力方向の下方に配設したものである。これにより、蒸発器５３で結露した水が蒸発器５３を通過する乾燥風によって飛散し、蒸発器５３の風下側に近接配置した凝縮器５４への付着を防止するようにしている。 FIG. 11 shows a configuration of a main part of a conventional clothes dryer described in Patent Document 1. As shown in FIG. As shown in FIG. 11, the evaporator 53 and the condenser 54 are provided close to the circulation air passage 52 of the heat pump device 51, and the lower end 53 a that is the gravity direction end of the evaporator 53 is provided at the gravity direction end of the condenser 54. It is arranged below the gravitational direction from a certain lower end 54a. As a result, the water condensed in the evaporator 53 is scattered by the dry air passing through the evaporator 53 and is prevented from adhering to the condenser 54 disposed close to the leeward side of the evaporator 53.

また、図１２に示すように、蒸発器６１の下方に結露水を回収する水回収凹部６２を形成し、水回収凹部６２に板状の抵抗体６３を設けることにより、通風ダクト６４内を流れる乾燥風が水回収凹部６２を通過し難くし、蒸発器６１の下端に付着している水滴が巻き上げられて飛散し、凝縮器６５への付着を防止することが考えられている（例えば、特許文献２参照）。 Further, as shown in FIG. 12, a water recovery recess 62 for recovering condensed water is formed below the evaporator 61, and a plate-like resistor 63 is provided in the water recovery recess 62, thereby flowing in the ventilation duct 64. It is considered that the dry air does not easily pass through the water recovery recess 62, and the water droplets adhering to the lower end of the evaporator 61 are rolled up and scattered to prevent adhesion to the condenser 65 (for example, patents). Reference 2).

しかしながら、前記従来の構成では、ヒートポンプ装置の高さが高くなるという問題があった。特許文献１に記載の構成では、蒸発器で結露した結露水が凝縮器へ飛散しないように、蒸発器の下端を凝縮器の下端より下方へ延長して形成することで高さが高くなる。また、特許文献２に記載の構成では、蒸発器の下端に付着している水滴が巻き上げられないように、水回収凹部の深さを深くすることで高さが高くなる。加えて、結露水を円滑に流出させるために、ヒートポンプ装置の下部に設けられる排水部の勾配を大きくする必要があり、ヒートポンプ装置の高さがさらに高くなるという問題があった。 However, the conventional configuration has a problem that the height of the heat pump device is increased. In the configuration described in Patent Document 1, the height is increased by forming the lower end of the evaporator downward from the lower end of the condenser so that the condensed water condensed by the evaporator is not scattered to the condenser. Moreover, in the structure of patent document 2, height is heightened by deepening the depth of a water collection | recovery recessed part so that the water droplet adhering to the lower end of an evaporator may not be rolled up. In addition, in order to smoothly flow out the condensed water, it is necessary to increase the gradient of the drainage section provided in the lower part of the heat pump device, and there is a problem that the height of the heat pump device is further increased.

また、洗濯機能を備えた衣類乾燥機に搭載されるヒートポンプ装置は、一般的に水槽底部の排水口より下方に配設されることから、ヒートポンプ装置の高さが高くなると、回転ドラムの重心位置が高くなり、振動が大きくなるという課題があった。 Further, since the heat pump device mounted on the clothes dryer having a washing function is generally disposed below the drain outlet at the bottom of the aquarium, when the height of the heat pump device increases, the center of gravity position of the rotating drum There is a problem that the vibration becomes high and the vibration becomes large.

制御手段４１は、ヒートポンプ装置１６の圧縮機１７、回転ドラム４を回転駆動するモータ９、乾燥風を送風する送風機２４等を制御し、洗濯、すすぎ、脱水、乾燥の各工程を逐次制御する。 The control means 41 controls the compressor 17 of the heat pump device 16, the motor 9 that rotationally drives the rotary drum 4, the blower 24 that blows dry air, and the like, and sequentially controls each step of washing, rinsing, dehydration, and drying.

以上のように構成された洗濯乾燥機について、以下その動作、作用を説明する。まず、洗い工程の手順を示す。最初に扉３８を開放し、開口６から回転ドラム４内に衣類ハ等の洗濯物を投入した後、扉３８を閉じ、操作ボタン（図示せず）を押して所望の運転プログラムを選択して運転を開始させる。 The operation and action of the washing / drying machine configured as described above will be described below. First, the procedure of the washing process is shown. First, the door 38 is opened, and laundry such as clothes is put into the rotary drum 4 from the opening 6, and then the door 38 is closed and an operation button (not shown) is pressed to select a desired operation program. To start.

制御手段４１は、扉３８が閉じられていることを確認した後、モータ９を駆動させ、回転にともなう負荷情報から、投入された衣類ハの量を判定する。その後、給水弁（図示せず）を開放して水槽２に水を貯める。衣類ハの量に応じてあらかじめ設定された水量が給水されると給水を停止し、モータ９を正転、反転を繰り返すなど、所定のプログラムにしたがって回転ドラム４を回転させる。 After confirming that the door 38 is closed, the control means 41 drives the motor 9 to determine the amount of clothes that have been thrown in from the load information that accompanies the rotation. Thereafter, the water supply valve (not shown) is opened to store water in the water tank 2. When a predetermined amount of water is supplied according to the amount of clothes, the water supply is stopped, and the rotating drum 4 is rotated according to a predetermined program, for example, the motor 9 is rotated normally and reversely.

回転ドラム４内の衣類ハは、バッフル１２によって回転方向へ持ち上げられて、回転ドラム４内の上方から落下し、叩き洗いの作用で汚れを落とし、所定の時間が経過すると洗い工程を終了する。 The clothing C in the rotating drum 4 is lifted in the rotating direction by the baffle 12, falls from above in the rotating drum 4, is cleaned by the action of tapping, and finishes the washing process when a predetermined time has elapsed.

洗い工程に続いて、次に、すすぎ工程を実行する。すすぎ工程では、排水、給水、モータ駆動というすすぎ作業を行う。水槽２に水を貯めた状態でモータ９を駆動させ、衣類ハに付着している洗剤成分や汚れ成分を汚れていない水の中へと移動させて汚れを落とす、すすぎを実行し、所定の時間が経過すると１回のすすぎ作業を終了し、これを２回繰り返した後、水槽２内の水を排出してすすぎ工程を終了する。 Following the washing step, a rinsing step is then performed. In the rinsing process, rinsing operations such as drainage, water supply, and motor drive are performed. The motor 9 is driven in a state where water is stored in the aquarium 2, and the detergent component and the dirt component adhering to the clothes are moved into the unclean water to remove the dirt, and the rinsing is performed. When time elapses, one rinsing operation is finished, and after repeating this twice, the water in the water tank 2 is discharged and the rinsing process is finished.

すすぎ工程に続いて、次に、脱水工程を実行する。脱水工程では、モータ９を駆動させて回転ドラム４を高速回転（例えば１４００ｒｐｍ）させる。このとき、回転数の増加にともなって、衣類ハに付加される遠心力が強まっていくため、衣類ハは回転ドラム４の内周面に張り付いていく。衣類ハに含まれる水分は、遠心力によって回転ドラム４の透孔１１から水槽２内へ移動し、脱水された水分は、排水路３７を経て機外へ排出される。 Following the rinsing step, a dehydration step is then performed. In the dehydration process, the motor 9 is driven to rotate the rotating drum 4 at a high speed (for example, 1400 rpm). At this time, the centrifugal force applied to the garment h increases as the number of rotations increases, so that the garment h sticks to the inner peripheral surface of the rotary drum 4. Moisture contained in the clothing c moves from the through hole 11 of the rotating drum 4 into the water tank 2 by centrifugal force, and the dehydrated moisture is discharged out of the machine through the drainage channel 37.

脱水時に回転ドラム４内の衣類ハに偏りが発生すると、ダンパーで下方から弾性支持されている水槽２が、回転ドラム４の高速回転で振れ回り現象が生じることがある。ヒートポンプ装置１６は、水槽２の下方に位置し、筐体１の側壁である右壁に近接して配置しているので、水槽２と離間することができる。 When the clothes in the rotary drum 4 are biased during dehydration, the water tank 2 elastically supported from below by the damper may cause a swinging phenomenon due to the high-speed rotation of the rotary drum 4. Since the heat pump device 16 is located below the water tank 2 and is disposed close to the right wall that is the side wall of the housing 1, it can be separated from the water tank 2.

また、送風機２４をヒートポンプ装置１６の後方に設け、送風機２４の上部２４ｃを水槽２後部の下端部２ａより上方に位置しているので、大型ファンの送風機２４を搭載することができる。 Moreover, since the air blower 24 is provided in the back of the heat pump apparatus 16, and the upper part 24c of the air blower 24 is located above the lower end part 2a of the rear part of the water tank 2, the air blower 24 of a large fan can be mounted.

次に、乾燥工程について説明する。洗い、すすぎ、脱水の各工程に続いて、乾燥工程を実行することができる。乾燥運転を開始すると、モータ９が回転し、回転ドラム４および送風機２４が回転して乾燥風の流れ（矢印ロ）が生じる。乾燥風は、回転ドラム４内の衣類ハから水分を奪って多湿となった後、排気口１４から乾燥フィルタ３６を通過し、排気ダクト１５ａを通ってヒートポンプ装置１６の蒸発器２０へ導かれる。回転ドラム４は、モータ９によりベルト１０を介して回転駆動され、衣類ハは、回転ドラム４内で撹拌される。 Next, the drying process will be described. Following the washing, rinsing and dewatering steps, a drying step can be performed. When the drying operation is started, the motor 9 is rotated, the rotating drum 4 and the blower 24 are rotated, and a flow of drying air (arrow B) is generated. The drying air takes moisture from the clothes in the rotary drum 4 and becomes humid, and then passes through the drying filter 36 from the exhaust port 14 and is guided to the evaporator 20 of the heat pump device 16 through the exhaust duct 15a. The rotating drum 4 is rotationally driven by the motor 9 via the belt 10, and the clothes C are agitated in the rotating drum 4.

ヒートポンプ装置１６の圧縮機１７を作動させると、冷媒が圧縮され、この圧力により凝縮器１８、絞り手段１９、蒸発器２０を循環する。凝縮器１８では、高圧状態で冷媒の熱が放出され、蒸発器２０では、絞り手段１９で減圧されて低圧状態となり冷媒へ熱が吸収される。このとき、送風機２４によって循環風路１５を流れる乾燥風を凝縮器１８の放熱によって加熱する。 When the compressor 17 of the heat pump device 16 is operated, the refrigerant is compressed, and the pressure circulates through the condenser 18, the throttle means 19, and the evaporator 20. In the condenser 18, the heat of the refrigerant is released in a high pressure state, and in the evaporator 20, the pressure is reduced by the throttle means 19 to be in a low pressure state, and the heat is absorbed into the refrigerant. At this time, the drying air flowing through the circulation air passage 15 is heated by the heat of the condenser 18 by the blower 24.

送風機２４により、給気ダクト１５ｃを通り、給気口１３から回転ドラム４内に送風された温風は、衣類ハの間を通るときに水分を奪って多湿となった後、排気口１４から乾燥フィルタ３６を通過してリント等の異物が除去され、排気ダクト１５ａを通ってヒートポンプ装置１６の蒸発器２０へ導かれる。この多湿の乾燥風は、蒸発器２０を通過する際に顕熱と潜熱が奪われて除湿され、乾いた空気と結露水に分離される。 The warm air blown into the rotary drum 4 from the air supply port 13 through the air supply duct 15c by the blower 24 is deprived of moisture when passing between the clothes, and then becomes humid. Foreign matters such as lint are removed through the drying filter 36 and led to the evaporator 20 of the heat pump device 16 through the exhaust duct 15a. When this humid drying air passes through the evaporator 20, sensible heat and latent heat are taken away and dehumidified, and separated into dry air and condensed water.

この乾いた空気は、凝縮器１８で加熱され、温風となって送風機２４により再び回転ドラム４内へ送風される。一方、蒸発器２０で結露した結露水は、排水ポンプ４０により排水管から排水路３７を通して機外へ排出する。 This dry air is heated by the condenser 18, becomes warm air, and is blown again into the rotary drum 4 by the blower 24. On the other hand, the condensed water condensed by the evaporator 20 is discharged from the drainage pipe 37 through the drainage channel 37 to the outside by the drainage pump 40.

衣類ハから水分を奪って排気口１４から排気される湿った空気は、水槽２の前方に位置し、筐体１の右壁に沿って水槽２の上方から下方に向かって延びる排気ダクト１５ａを通り、筐体１内の前面近傍に位置する流入側２３ａからケース２２内に流入する。 Moist air that is deprived of moisture from the clothes and exhausted from the exhaust port 14 is located in front of the aquarium 2 and extends along the right wall of the housing 1 through an exhaust duct 15a extending downward from above the aquarium 2. As a result, the air flows into the case 22 from the inflow side 23 a located near the front surface in the housing 1.

ケース２２によって形成された熱交換室２３内に流入した多湿の乾燥風は、蒸発器２０を通過して冷却され結露して除湿される。蒸発器２０のフィン全体に結露して発生した結露水は水滴化し、やがて自重によりフィンを伝って下方へ移動し、蒸発器２０の下方に形成されている空間部２７と溝部３１に落下する。 The humid dry air that has flowed into the heat exchange chamber 23 formed by the case 22 passes through the evaporator 20 and is cooled and condensed to be dehumidified. Condensed water generated by dew condensation on the entire fins of the evaporator 20 is converted into water droplets, and eventually moves downward through the fins due to its own weight, and falls into the space portion 27 and the groove portion 31 formed below the evaporator 20.

空間部２７に落下した結露水は、下り傾斜の底部を流入部３２に向かって流れ、溝部３１の一方の端部３１ａ側に設けた流入部３２から溝部３１に流入する。また、一方の配管室２９ａに突出した管路２１の表面に結露した水も一方の配管室２９ａに落下し、流入部３２から溝部３１に流入する。さらに、フィンを伝って下方へ移動した結露水は、蒸発器２０を流れる乾燥風の送風方向へ流されて溝部３１に落下する。 Condensed water that has fallen into the space portion 27 flows along the downwardly inclined bottom toward the inflow portion 32, and flows into the groove portion 31 from the inflow portion 32 provided on the one end portion 31 a side of the groove portion 31. Further, water condensed on the surface of the pipeline 21 protruding into the one piping chamber 29 a also falls into the one piping chamber 29 a and flows into the groove portion 31 from the inflow portion 32. Furthermore, the dew condensation water that has moved downward through the fins is caused to flow in the blowing direction of the drying air flowing through the evaporator 20 and falls into the groove 31.

溝部３１に落下した結露水と、流入部３２から溝部３１に流入した結露水は、蒸発器２０と凝縮器１８の間の熱交換室２３の底部に位置し、かつ、蒸発器２０と凝縮器１８を通過する乾燥風の流れと交差する方向に形成した下り傾斜の溝部３１を流出部３３に向かって流れる。 The condensed water that has fallen into the groove 31 and the condensed water that has flowed into the groove 31 from the inlet 32 are located at the bottom of the heat exchange chamber 23 between the evaporator 20 and the condenser 18, and the evaporator 20 and the condenser. A downwardly inclined groove 31 formed in a direction intersecting with the flow of the drying air passing through 18 flows toward the outflow portion 33.

ここで、蒸発器２０の下方に形成されている空間部２７に落下した結露水は、排水口３０に近い位置、すなわち、蒸発器支持部２５の他方の配管室２９ｂ側から排水口３０へ流出させるのが一般的であるが、結露水とともに空間部２７から他方の配管室２９ｂに流出した乾燥風は、溝部３１の流出部３３を横切って凝縮器１８側へ流れ、循環風路１５へ戻る風の流れが形成される。 Here, the dew condensation water that has dropped into the space 27 formed below the evaporator 20 flows out from the position close to the drain port 30, that is, from the other piping chamber 29 b side of the evaporator support unit 25 to the drain port 30. In general, the dry air that has flowed out of the space portion 27 into the other piping chamber 29 b together with the dew condensation water flows to the condenser 18 side across the outflow portion 33 of the groove portion 31 and returns to the circulation air passage 15. A wind flow is formed.

溝部３１に落下した結露水は、この風の流れによって流出部３３からの流出が阻まれて溝部３１に滞留する。乾燥運転の進行により結露水の発生が多くなると、溝部３１に落下した結露水の水位が上昇する。その結果、蒸発器２０から凝縮器１８へ流れる乾燥風に、溝部３１に溜まった結露水が巻き込まれ、凝縮器１８側へ飛散する事態となる。 Condensed water that has fallen into the groove portion 31 is prevented from flowing out from the outflow portion 33 by the flow of the wind and stays in the groove portion 31. When the amount of condensed water increases due to the progress of the drying operation, the level of the condensed water that has fallen into the groove 31 increases. As a result, the dewed water accumulated in the groove 31 is caught in the dry air flowing from the evaporator 20 to the condenser 18 and scattered to the condenser 18 side.

そこで、蒸発器２０を通る乾燥風の一部が流入する流入部３２を溝部３１の一方の端部３１ａ側に設け、流入部３２から溝部３１に流入した乾燥風によって、溝部３１に落下した結露水と、流入部３２から溝部３１に流入した結露水を、溝部３１の他方の端部３１ｂ側に設けた流出部３３側へ押し出し、流出部３３への流れを加速させるとともに、溝部３１からの結露水の流出を遮る風の流れを解消している。 Therefore, an inflow portion 32 into which a part of the dry air passing through the evaporator 20 flows is provided on one end 31a side of the groove portion 31, and the dew condensation that has fallen into the groove portion 31 due to the dry air flowing into the groove portion 31 from the inflow portion 32. Water and condensed water flowing into the groove 31 from the inflow part 32 are pushed out to the outflow part 33 side provided on the other end 31b side of the groove part 31 to accelerate the flow to the outflow part 33, and from the groove part 31 The flow of wind that blocks outflow of condensed water is eliminated.

流出部３３から流出した結露水は、他方の配管室２９ｂに形成した水溜部３５に集められ、排水口３０から排出された後、排水ポンプ４０によって機外へ排出される。流出部３３から流出した乾燥風は、隔壁２９ｃに設けた開口部３４から凝縮器１８の下方に形成された空間部２８内へ流入し、熱交換室２３の流出側２３ｂから循環風路１５に戻り循環する。 Condensed water flowing out from the outflow portion 33 is collected in the water reservoir 35 formed in the other piping chamber 29b, discharged from the drain port 30, and then discharged outside the apparatus by the drain pump 40. The dry air that has flowed out from the outflow portion 33 flows into the space portion 28 formed below the condenser 18 from the opening 34 provided in the partition wall 29c, and enters the circulation air passage 15 from the outflow side 23b of the heat exchange chamber 23. Cycle back.

溝部３１に落下した結露水は、溝部３１の一方の端部３１ａ側から他方の端部３１ｂ側への下り傾斜が緩やかであると、流出部３３から流出し難く、溝部３１に留まって水嵩が増しやすい。空間部２７に落下した結露水を流入部３２から溝部３１へ流入させることにより、溝部３１に留まっている結露水とともに流出部３３へ移動させることができる。 Condensed water that has fallen into the groove 31 is less likely to flow out of the outflow portion 33 when the downward slope from the one end portion 31a side to the other end portion 31b side of the groove portion 31 is gentle, and remains in the groove portion 31 and has a water volume. Easy to increase. By allowing the condensed water that has fallen into the space portion 27 to flow into the groove portion 31 from the inflow portion 32, it can be moved to the outflow portion 33 together with the condensed water remaining in the groove portion 31.

さらに、乾燥風の一部が流入部３２から溝部３１に流入することにより、溝部３１を流出部３３へ流れる結露水の移動を加速させることができ、結露水が溝部３１に滞留することなく、円滑に排水口３０から排出することができる。 Furthermore, when a part of dry air flows into the groove part 31 from the inflow part 32, the movement of the dew condensation water flowing through the groove part 31 to the outflow part 33 can be accelerated, and the dew condensation water does not stay in the groove part 31, It can be smoothly discharged from the drain port 30.

したがって、溝部３１を通して排出される結露水が、乾燥風の流れに巻き込まれることなく、凝縮器１８への結露水の飛散を防止することができる。また、蒸発器２０で発生した結露水の円滑な排出により、蒸発器２０と凝縮器１８を収容したヒートポンプ装置１６の熱交換室２３の高さを低くすることができ、ヒートポンプ装置１６の上方に配設される回転ドラム４の位置を低くして、振動を低減することができる。 Therefore, the dew condensation water discharged through the groove part 31 can be prevented from being scattered to the condenser 18 without being involved in the flow of the drying air. Moreover, the smooth discharge of the dew condensation water generated in the evaporator 20 can reduce the height of the heat exchange chamber 23 of the heat pump device 16 that accommodates the evaporator 20 and the condenser 18, and is located above the heat pump device 16. The vibration can be reduced by lowering the position of the rotary drum 4 disposed.

すなわち、排気口１４から排気された乾燥風は、水槽２の下方に設けたヒートポンプ装置１６を後方へ流れて、筐体１内の右壁側で送風機２４に到達する。送風機２４は、ヒートポンプ装置１６の後方に設け、送風機２４から前方へ延びるダクト１５ｂを介してヒートポンプ装置１６と連通接続し、送風機２４の上部２４ｃを水槽２後部の下端部２ａより上方に位置するように構成している。 That is, the dry air exhausted from the exhaust port 14 flows backward through the heat pump device 16 provided below the water tank 2 and reaches the blower 24 on the right wall side in the housing 1. The blower 24 is provided behind the heat pump device 16 and is connected to the heat pump device 16 through a duct 15b extending forward from the blower 24 so that the upper portion 24c of the blower 24 is positioned above the lower end portion 2a of the rear portion of the water tank 2. It is configured.

これにより、ヒートポンプ装置１６と送風機２４を筐体１内の下部にコンパクトに構成し、水槽２の位置を低くして脱水時の振動を抑制し、筐体１の高さを低くして小型化することができる。 Accordingly, the heat pump device 16 and the blower 24 are compactly configured in the lower portion of the housing 1, the position of the water tank 2 is lowered to suppress vibration during dehydration, and the height of the housing 1 is lowered to reduce the size. can do.
