本発明は、洗濯・脱水と乾燥を同一回転槽内で行う洗濯乾燥機に関するものである。 The present invention relates to a washing / drying machine that performs washing / dehydration and drying in the same rotating tank.
従来のドラム式の洗濯乾燥機は図１１に示すような構成であった。以下、その構成について説明する。 A conventional drum-type washing and drying machine has a configuration as shown in FIG. Hereinafter, the configuration will be described.
図１１に示すように、筐体１の内部には、複数のサスペンション２によって弾性的に支持された円筒状の水槽３を設け、洗濯・脱水時の振動をサスペンション２によって吸収する構成としている。水槽３の内部には、洗濯または乾燥対象物４（以下、衣類という）を収容する円筒状で横軸型の回転槽５を回転可能に配設し、駆動モータ６により回転軸６ａを回転させて回転駆動する。 As shown in FIG. 11, a cylindrical water tank 3 elastically supported by a plurality of suspensions 2 is provided inside the housing 1, and the suspension 2 absorbs vibration during washing and dehydration. Inside the water tank 3, a cylindrical, horizontal axis type rotating tank 5 that accommodates an object 4 to be washed or dried (hereinafter referred to as clothing) is rotatably arranged, and a rotating shaft 6 a is rotated by a drive motor 6. To rotate.
回転槽５の内壁には、衣類を撹拌する複数のバッフル（図示せず）が設けられ、回転槽５の周壁には小孔５ａを多数設けている。前記筐体１の前面には衣類４を出し入れする開口部１ａと、これを開閉する扉７が設けられている。水槽３および回転槽５の前面側にも同様の開口部３ａ、５ｂを有し、この水槽３の開口部３ａはベローズ８によって筐体１の開口部１ａと水密に連結されている。水槽３の底部には洗濯水を排出する排水口９を有し、排水弁１０を介して排水ホース１１に連結され、その先端部は機外に導出されている。 A plurality of baffles (not shown) for stirring clothes are provided on the inner wall of the rotating tub 5, and a plurality of small holes 5 a are provided on the peripheral wall of the rotating tub 5. On the front surface of the housing 1, there are provided an opening 1a for taking clothes 4 in and out and a door 7 for opening and closing the opening 1a. Similar openings 3 a and 5 b are also provided on the front side of the water tank 3 and the rotating tank 5, and the opening 3 a of the water tank 3 is water-tightly connected to the opening 1 a of the housing 1 by a bellows 8. The bottom of the aquarium 3 has a drain port 9 for discharging washing water, and is connected to a drain hose 11 via a drain valve 10, and its tip is led out of the machine.
送風機１２は、ヒータ１３によって加熱された温風を給気口１４から回転槽５内に送風供給するものであり、水槽３の反開口部側と回転槽５との隙間にはラビリンスシール構成１９を有している。循環ダクト１５は、回転槽５および水槽３を通過した湿った乾燥用空気の除湿を行うもので、一端を水槽３の下部の排気口１６に接続し、他端を送風機１２に接続している。給水弁１７は、水道の蛇口等に接続された給水ホース１８からの給水を制御する。 The blower 12 supplies hot air heated by the heater 13 from the air supply port 14 into the rotating tub 5, and a labyrinth seal configuration 19 is provided in a gap between the counter opening side of the water tub 3 and the rotating tub 5. have. The circulation duct 15 performs dehumidification of the damp drying air that has passed through the rotary tank 5 and the water tank 3, and has one end connected to the exhaust port 16 at the bottom of the water tank 3 and the other end connected to the blower 12. . The water supply valve 17 controls water supply from a water supply hose 18 connected to a tap or the like of a water supply.
上記構成において、洗濯運転を行う場合は、扉７を開いて回転槽５内へ衣類４および洗剤を入れて運転を開始する。 In the above configuration, when the washing operation is performed, the door 7 is opened, the clothes 4 and the detergent are put into the rotating tub 5, and the operation is started.
まず、給水弁１７が洗濯水側の給水口を開き、水槽３および回転槽５内に所定量の水が供給されると、駆動モータ６が作動し、回転槽５が回転駆動され洗浄動作を行う。所定時間後、駆動モータ６が停止して排水弁１０が開き、汚れた水が回転槽５および水槽３から排水され、排水ホース１１を介して機外の排水場所へ排水される。 First, when the water supply valve 17 opens the water supply port on the washing water side and a predetermined amount of water is supplied into the water tank 3 and the rotary tank 5, the drive motor 6 is activated, and the rotary tank 5 is driven to rotate to perform a washing operation. Do. After a predetermined time, the drive motor 6 is stopped, the drain valve 10 is opened, and dirty water is drained from the rotary tank 5 and the water tank 3 and drained to a drainage place outside the machine via the drain hose 11.
次に、上記と同様に水槽３および回転槽５に水が供給され、すすぎ動作を行う。すすぎ動作が終了すると排水弁１０が開いて排水された後、回転槽５が駆動モータ６により高速で回転駆動されることにより、衣類４の脱水が行われる。 Next, in the same manner as described above, water is supplied to the water tank 3 and the rotary tank 5 to perform a rinsing operation. When the rinsing operation is completed, the drain valve 10 is opened and drained, and then the rotating tub 5 is rotationally driven by the drive motor 6 at a high speed, whereby the clothes 4 are dehydrated.
以上のように洗濯運転が終了すると、乾燥運転が開始する。 When the washing operation is completed as described above, the drying operation is started.
乾燥工程では駆動モータ６により低速で回転槽５を回転駆動させ衣類４を撹拌しながら、ヒータ１３で加熱された空気は温風となり、送風機１２により矢印ａの方向に送風され、給気口１４から回転槽５内へ送り込まれる。この温風は、衣類４の水分を奪った後、回転槽５の小孔５ａから水槽３内を通過して排気口１６を経て循環ダクト１５へ至る。 In the drying process, the air heated by the heater 13 becomes warm air while rotating the rotating tub 5 at a low speed by the drive motor 6 and stirring the clothes 4, and is blown in the direction of arrow a by the blower 12. Into the rotary tank 5. This hot air takes away moisture from the garment 4, then passes through the water tank 3 through the small hole 5 a of the rotating tub 5 and reaches the circulation duct 15 through the exhaust port 16.
このとき給水弁１７が冷却水側の給水口を開いており、循環ダクト１５内には冷却水が注水されている。衣類４の水分を奪って湿気を含んだ温風がこの循環ダクト１５内を通過
するとき、冷却水により冷却されて水分の結露が起こり、湿った温風は除湿されて矢印に示すように再び送風機１２へ戻る。この冷却水および結露水は排水弁１０を介して機外へ排水される。この送風機１２、ヒータ１３、給気口１４、回転槽５、水槽３、排気口１６、循環ダクト１５の循環経路で温風を循環させることにより、回転槽５内の衣類４を乾燥させることができる。
At this time, the water supply valve 17 opens the water supply port on the cooling water side, and the cooling water is poured into the circulation duct 15. When the warm air containing moisture from the clothes 4 deprives the moisture and passes through the circulation duct 15, it is cooled by the cooling water to cause condensation of the moisture, and the wet warm air is dehumidified and again as shown by the arrow. Return to the blower 12. This cooling water and dew condensation water is drained out of the machine via the drain valve 10. By circulating hot air through the circulation path of the blower 12, the heater 13, the air supply port 14, the rotary tank 5, the water tank 3, the exhaust port 16, and the circulation duct 15, the clothes 4 in the rotary tank 5 can be dried. it can.
上記従来の構成では、矢印ｄから送風機１２により矢印ａの方向に送風された温風は１００％衣類４の乾燥に使用されることなく矢印ｂ及びｃの方向に分かれ、矢印ｃの方向へ流れる温風はラビリンスシール構成１９を通過して直接排気口１６を経て循環ダクト１５へ至る。そのため、給気口１４から回転槽５内へ送り込まれる温風の量は、衣類の量が増すに従って通風抵抗が増加することに起因して低減する。すなわち衣類の量が増加するに従って衣類に接触する温風の量が少なくなり乾燥性能が劣るという課題があった。 In the above conventional configuration, the warm air blown from the arrow d by the blower 12 in the direction of the arrow a is divided into the directions of the arrows b and c without being used for drying the clothes 4 and flows in the direction of the arrow c. The warm air passes through the labyrinth seal structure 19 and directly reaches the circulation duct 15 through the exhaust port 16. Therefore, the amount of warm air sent into the rotary tub 5 from the air supply port 14 is reduced due to the increase in ventilation resistance as the amount of clothing increases. That is, as the amount of clothing increases, there is a problem that the amount of warm air that comes into contact with the clothing decreases and the drying performance deteriorates.
また、ラビリンスシール構成１９は、水槽３に対する回転槽５の回転時における特に脱水時の偏心量を考慮されて、停止時で３ｍｍから５ｍｍの隙間を有して、通風回路を迷路状にすることにより、通風抵抗を増加させて空気の通過量を極力低減させ、乾燥効率向上に寄与するものである。 Further, the labyrinth seal configuration 19 takes into account the amount of eccentricity when the rotating tub 5 is rotated with respect to the water tub 3, particularly during dehydration, and has a gap of 3 mm to 5 mm when stopped to make the ventilation circuit a maze. As a result, the ventilation resistance is increased, the amount of air passing is reduced as much as possible, and the drying efficiency is improved.
そこで、回転槽の開口部の内周部に壁部材を設けた洗濯乾燥機が提案されている（例えば、特許文献１参照）。この構成によれば、より効率よく衣類の乾燥が行えることが分かっている。
しかしながら、上述したような通風回路構成では、衣類の量が増加するに従って回転槽内に流入する温風量が激減するため、乾燥性能が劣るという課題があり、この衣類量増加時の乾燥性能向上が不可欠であった。 However, in the ventilation circuit configuration as described above, since the amount of warm air flowing into the rotating tub drastically decreases as the amount of clothing increases, there is a problem that the drying performance is inferior, and the improvement of the drying performance when the amount of clothing increases. It was essential.
本発明は、上記従来の課題を解決するもので、送風機１２により矢印ｄの方向に送風された温風は衣類４の量が増加しても１００％衣類４の乾燥に使用されるため乾燥性能に優れた洗濯乾燥機を実現することを目的とする。 The present invention solves the above-described conventional problems, and the warm air blown in the direction of arrow d by the blower 12 is used for drying the clothing 4 even if the amount of the clothing 4 is increased. The purpose is to realize an excellent washing and drying machine.
上記従来の課題を解決するために、本発明の洗濯乾燥機は、筐体内に弾性支持され下部に排気口を有する水槽と、前面側に洗濯物の出し入れのための開口部、背面部の側壁に給気口、円筒状の周壁に多数の小孔を有し前記水槽内に回転可能に設けられ前記洗濯物を収容する横軸型の回転槽と、前記水槽の外面に設けられ、一端より前記回転槽の前記小孔を通過して前記水槽の前記排気口から排出された空気を導入する供給風路と、前記水槽の背面に設けられ、一端が前記水槽の背面部の側壁と前記回転槽の背面部の側壁の間に連通し、他端が前記供給風路の他端に連通した送風路と、前記送風路に設けられ、温風を前記水槽内へ供給する送風装置と、可撓変形可能な弾性体で前記回転槽と略同心軸となる環状に且つ先端部が根元部に比べて薄くなるように形成され前記送風装置の停止時に前記送風路内に延出した先端が前記回転槽と所定間隔を維持するように前記水槽に取り付けられたシール部材を具備し、前記シール部材は、乾燥工程での前記送風路内への送風時に、前記送風に伴う風圧を受けて前記シール部材の先端が前記回転槽の背面部の側壁に当接して、前記送風路からの送風を、前記シール部材の環状領域内に位置する前記給気口を介して前記回転槽内へ導くようにしたものである。 In order to solve the above-described conventional problems, a washing and drying machine according to the present invention includes a water tank elastically supported in a housing and having an exhaust port at a lower portion, an opening for taking in and out laundry on the front side, and a side wall on the back side. air supply port, a rotary tub of the horizontal axis type rotatably provided a number of the water tank has a small hole in a cylindrical peripheral wall to accommodate the laundry is provided on an outer surface of the tub, a from one end a supply air path for introducing the air discharged through the small holes of the rotary tub from the outlet port of the water tank, provided on the rear surface of said water tank, said rotation side wall of the rear portion of one end of the water tub communicating between the side walls of the rear of the vessel, a blowing path and the other end is communicated with the other end of the supply air path, provided in the air passage, a blower for supplying hot air into the water tank, variable thin and tip in an annular shape serving as the rotating tub substantially coaxially deformable elastic body as compared with the root portion Deflection So as to be formed include a sealing member attached to the water tub such that the tip extending into the blowing passage in stopping the blower to maintain the rotary tub by a predetermined distance, the seal member is dried wherein when blowing into blast path in step, the tip of the seal member receives the wind pressure caused by the blowing is abut against the side wall of the rear portion of the rotating tub, the air blowing from the blowing passage, the seal It is made to guide into the rotating tank through the air supply port located in the annular region of the member .

When the air blower 21 is operated, the seal member 22 is flexibly deformed by the wind pressure and a thermal deformation action caused by hot air described later to prevent the passage of gas. It is arranged concentrically with the rotating tank 5.
ここで、洗浄工程や濯ぎ行程のように送風装置２１が停止している場合、前記シール部材２２は図３に示す如く被シール部である回転槽５壁面との間に３ｍｍから５ｍｍの隙間Ａを有している。乾燥工程時においては、前記送風装置２１が稼働時するので、気体の通過を防止するシール機能を満たす為にシール部材と被シール部材との間の隙間は塞がれる。 Here, when the blower 21 is stopped as in a cleaning process or a rinsing process, the sealing member 22 has a gap A of 3 mm to 5 mm between the sealing tank 22 and the wall surface of the rotating tub 5 as a sealed portion as shown in FIG. have. In the drying process, since the blower 21 is in operation, the gap between the sealing member and the member to be sealed is closed in order to satisfy the sealing function for preventing the passage of gas.
前記シール部材２２は、前記送風機１２による風圧および熱変形作用を受けて可撓変形するように、例えばゴム材のような柔らかい弾性体から形成されており、図３の断面で示すように、根元部から先端部に向かって薄くなるように形成されていると共に、先端と根元の中間部には、その肉厚が厚く、薄くを交互に繰り返す肉厚変化部２２ａが形成されている。この肉厚変化部２２ａにより、前記シール部材２２は、小さな風圧によっても可撓変形を行い易くなっている。この構成は、肉厚変化部２２ａに限らず、やや肉厚が薄い一様の肉厚の蛇腹状であってもよい。さらに、前記シール部材２２は、熱膨張係数の異なる少なくとも２層の材料で構成されており、反回転槽５（水槽３内面）側にその膨張係数の大きい材料を使用し、温風を受けたときに、その熱で膨張し、シール部材２２の先端を回転槽５側へ近づき易くしている。このためのシール部材２２の構成として、使用する材料は２層に限らずそれ以上であってもよい。 The sealing member 22 is formed of a soft elastic body such as a rubber material so as to be flexibly deformed by receiving the wind pressure and thermal deformation action of the blower 12, and as shown in the cross section of FIG. In addition to being formed so as to become thinner from the portion toward the tip portion, a thickness changing portion 22a is formed in the middle portion between the tip and the base, and the thickness thereof is thick and the thickness is changed alternately. The thickness changing portion 22a facilitates the flexible deformation of the seal member 22 even with a small wind pressure. This configuration is not limited to the thickness changing portion 22a, but may be a uniform thickness bellows with a slightly small thickness. Further, the sealing member 22 is composed of at least two layers of materials having different thermal expansion coefficients, and a material having a large expansion coefficient is used on the counter-rotating tank 5 (inner surface of the water tank 3) to receive hot air. Sometimes, the heat expands to make it easier for the tip of the seal member 22 to approach the rotating tub 5 side. As a configuration of the seal member 22 for this purpose, the material to be used is not limited to two layers but may be more than that.
なお、前記送風路２０は、前記送風機１２が洗浄時の水の影響を受けないようにその開口位置等について配慮されていることは言うまでもない。 In addition, it cannot be overemphasized that the opening position etc. of the said ventilation path 20 are considered so that the said air blower 12 may not receive the influence of the water at the time of washing | cleaning.
次に、上記構成における洗濯乾燥機の動作について説明する。 Next, the operation of the washing / drying machine having the above configuration will be described.
洗浄工程では、排水弁１０を閉じた状態で水槽３内に所定の水位（図示せず）に達するまで給水を行い、駆動モータ６により衣類４と洗浄水の入った回転槽５を回転させて洗浄を行う。 In the washing process, water is supplied into the water tank 3 with the drain valve 10 closed until a predetermined water level (not shown) is reached, and the drive motor 6 rotates the rotating tank 5 containing the clothes 4 and the washing water. Wash.
このとき送風装置２１は稼働していないので、シール部材２２と被シール部との間には隙間があり、両者が接触することなく洗浄工程は終了する。したがって、前記シール部材２２の摩耗あるいは前記両者の接触による摩擦音等の発生も無いため、シール部の長寿命化がはかれ、またシール部材２２の耐久性の向上や低騒音化がはかれるものである。 At this time, since the blower device 21 is not operating, there is a gap between the seal member 22 and the sealed portion, and the cleaning process ends without contact between the two. Therefore, since there is no wear of the seal member 22 or generation of frictional noise due to contact between the both, the life of the seal portion can be extended, and the durability of the seal member 22 can be improved and the noise can be reduced. .
また、洗浄後の濯ぎ工程では、前記洗浄工程と同様に水槽３内に給水され、回転槽５を回転させて衣類４の濯ぎを行う。 In the rinsing process after washing, water is supplied into the water tank 3 as in the washing process, and the garment 4 is rinsed by rotating the rotating tank 5.
この場合においても、前記シール部材２２と被シール部との関係は、前記洗浄工程と同様であり、耐久性の向上や低騒音化がはかれるものである。 Also in this case, the relationship between the sealing member 22 and the sealed portion is the same as that in the cleaning step, and durability can be improved and noise can be reduced.
さらに、脱水工程では、排水弁１０を開いて機外へ水を排水した後、駆動モータ６により衣類４の入った回転槽５を高速回転して脱水する。このとき、前記回転槽５が偏心状態
で運転されても、前記シール部材２２と被シール部との隙間は確保されるため、同様に耐久性の向上や低騒音化がはかれるものである。
Further, in the dehydration step, the drain valve 10 is opened to drain water to the outside of the machine, and then the rotating tub 5 containing the clothing 4 is rotated at high speed by the drive motor 6 to dehydrate. At this time, even if the rotating tub 5 is operated in an eccentric state, the gap between the seal member 22 and the sealed portion is secured, and thus the durability and noise reduction can be similarly achieved.
また、乾燥工程では、送風機１２が作動し、ヒータ１３により加熱された温風が送風路２０を通って給気口１４から回転槽５内に送風される。この状態において、前記回転槽５は、駆動モータ６により低速で回転駆動され、衣類４は上下に撹拌される。 Further, in the drying process, the blower 12 is operated, and the warm air heated by the heater 13 is blown into the rotary tank 5 from the air supply port 14 through the blower passage 20. In this state, the rotating tub 5 is rotationally driven at a low speed by the drive motor 6, and the clothes 4 are stirred up and down.
ここで、前記水槽３側に固定されたシール部材２２は、その先端が送風路２０内に延出しているため、前記送風装置２１により温風が送風路２０を通過すると、その送風圧力を受け、肉厚変化部２２ａを主体に撓み、その先端部が図４に示す如く被シール部側である回転槽５の側壁に密着し、送風路２０からの送風を給気口１４へ導く。このシール部材２２先端と回転槽５側壁との当接は、シール部材２２が環状に形成されているため、前記回転槽５の側壁に設けられた全ての給気口１４をその環状領域内にして送風路２０からの風を回転槽５内に導く。したがって、前記温風は直接排気口１６へ流れず必ず給気口１４より水槽３内へ入り、衣類４の乾燥を行うため、乾燥性能が向上する。そして、給気口１４から回転槽５内へ送り込まれた温風は、衣類４の水分を奪った後、回転槽５の小孔５ａから水槽３内を通過して排気口１６を経て循環ダクト１５へ至る。 Here, since the tip of the seal member 22 fixed to the water tank 3 side extends into the air passage 20, when warm air passes through the air passage 20 by the air blower 21, the air pressure is received. Then, the thickness changing portion 22a is mainly bent, and the tip portion thereof is in close contact with the side wall of the rotating tub 5 on the sealed portion side as shown in FIG. The contact between the tip of the seal member 22 and the side wall of the rotary tank 5 is such that the seal member 22 is formed in an annular shape, so that all the air supply ports 14 provided on the side wall of the rotary tank 5 are placed in the annular region. Then, the wind from the air passage 20 is guided into the rotary tank 5. Therefore, the warm air does not flow directly to the exhaust port 16 but always enters the water tank 3 through the air supply port 14 and dries the clothes 4, so that the drying performance is improved. And the warm air sent into the rotary tank 5 from the air supply port 14 deprives the moisture of the clothing 4, then passes through the water tank 3 from the small hole 5 a of the rotary tank 5, and passes through the exhaust port 16 to circulate the duct. To 15.
ここで、前記送風路２０を流れる温風は、前記回転槽５内の衣服４の量に影響して多少その風圧が変化するが、前記シール部材２２の可撓変形は、定められた衣服４の量範囲であれば十分その圧力に追従してシール効果を発揮するよう前記材料、肉厚変化部２２ａの肉厚等が設定されている。 Here, the warm air flowing through the air blowing path 20 affects the amount of the clothes 4 in the rotating tub 5 and the wind pressure changes somewhat. However, the flexible deformation of the seal member 22 is determined by the determined clothes 4. The material, the thickness of the thickness changing portion 22a, etc. are set so as to sufficiently follow the pressure and exhibit the sealing effect.
さらに、この乾燥工程においては、給水弁１７における冷却水側の給水口が開いており、循環ダクト１５内には冷却水が注水されている。したがって、前記衣類４の水分を奪って湿気を含んだ温風は、この循環ダクト１５内を通過するとき、冷却水により冷却されて水分の結露が起こり、湿った温風は除湿されて矢印ｄに示すように再び送風機１２へ戻る。一方、前記冷却水および結露水は、排水弁１０を介して機外へ排水される。 Further, in this drying process, the water supply port on the cooling water side of the water supply valve 17 is open, and cooling water is poured into the circulation duct 15. Therefore, when the warm air deprived of moisture from the garment 4 passes through the circulation duct 15, it is cooled by the cooling water to cause condensation of the moisture, and the moist warm air is dehumidified and the arrow d As shown in FIG. On the other hand, the cooling water and the dew condensation water are drained out of the apparatus through the drain valve 10.
このように、前記送風機１２、ヒータ１３、給気口１４、回転槽５、水槽３、排気口１６、循環ダクト１５の循環経路で温風を循環させることにより、回転槽５内の衣類４を乾燥させることができる。 In this way, by circulating hot air through the circulation path of the blower 12, the heater 13, the air supply port 14, the rotating tank 5, the water tank 3, the exhaust port 16, and the circulation duct 15, the clothing 4 in the rotating tank 5 is made to circulate. Can be dried.
また、前記シール部材２２は、その断面が根元部から先端部に向かって薄くなっていることや一部に肉厚変化部２２ａを設けていることから、衣類４の量に左右されることなく、わずかな風量による風圧で変形し被シール部へ密着する。さらに熱膨張率の異なる少なくとも２層以上の材料でシール部材２２を構成しているので、衣類４の量に影響してわずかな風量となった場合においても、空気の温度上昇に伴いその先端部が被シール部側へ熱膨張変形し、密着するため、乾燥効率の向上がはかれるものである。 Further, the sealing member 22 is not affected by the amount of the garment 4 because the cross-section is thinner from the root part toward the tip part or the thickness changing part 22a is provided in part. It is deformed by the wind pressure due to a slight air volume and adheres to the sealed part. Furthermore, since the sealing member 22 is made of at least two layers of materials having different coefficients of thermal expansion, even if the air volume is small due to the amount of the garment 4, the tip portion thereof increases as the temperature of the air increases. Is thermally expanded and deformed toward the sealed portion side, so that the drying efficiency is improved.
上記実施の形態１によれば、乾燥工程時において送風装置２１により温風が送風路２０を通過する際に、その風圧および温風温度によりシール部材２２を被シール部側へ可撓変形させるもので、前記シール部材２２の可撓変形によりシール機能を発揮させるため、温風は直接排気口１６へ流れず、給気口１４より水槽３内へ導かれ、衣類４の乾燥を行う。その結果、衣類４等の乾燥性能が向上する。 According to the first embodiment, when warm air passes through the air blowing path 20 by the blower 21 during the drying process, the sealing member 22 is flexibly deformed toward the sealed portion side by the wind pressure and the warm air temperature. In order to exhibit the sealing function by the flexible deformation of the sealing member 22, the hot air does not flow directly to the exhaust port 16, but is guided into the water tank 3 through the air supply port 14, and the clothes 4 are dried. As a result, the drying performance of the clothing 4 and the like is improved.
また洗浄工程及び濯ぎ行程においては、送風装置２１が稼働しないため、シール部材２２への風圧は発生しない。その結果、シール部材２２と被シール部との隙間は確保され、回転槽５の回転に伴う摩擦によってシール部材２２が無意味に摩耗することがなく、シール部材２２の耐久性を向上させることができる。また擦れ音がしないことから低騒音運転
が可能となる。また、乾燥工程時にシール部材と被シール部との間に体積したリントを洗浄行程、濯ぎ行程で除去することができ、乾燥性能及び耐久性能に優れた洗濯乾燥機を実現することができる。
Further, in the cleaning process and the rinsing process, the air blower 21 does not operate, so that no wind pressure is generated on the seal member 22. As a result, a gap between the seal member 22 and the sealed portion is ensured, and the seal member 22 is not worn meaninglessly due to friction associated with the rotation of the rotating tub 5, and the durability of the seal member 22 can be improved. it can. Further, since there is no rubbing sound, low noise operation is possible. Further, the lint that has been volumed between the sealing member and the sealed portion during the drying process can be removed by the washing process and the rinsing process, and a washing / drying machine having excellent drying performance and durability can be realized.
なお、本実施の形態１では、ヒータ１３および送風機１２を駆動モータ６の下部に設置しているが駆動モータ６の上部に設置しても良い。 In the first embodiment, the heater 13 and the blower 12 are installed below the drive motor 6, but may be installed above the drive motor 6.
また本実施の形態１では乾燥用空気の加熱にヒータを使用し、除湿に給水口からの冷却水を使用しているが、冷媒圧縮機を使用した加熱及び除湿（冷却）を行うヒートポンプサイクルを使用しても良い。 In the first embodiment, a heater is used for heating the drying air, and cooling water from the water supply port is used for dehumidification. However, a heat pump cycle that performs heating and dehumidification (cooling) using a refrigerant compressor is used. May be used.

本実施の形態は、図９に示す如く、回転軸６ａを有する回転槽５の面と送風路２０を介して向かい合う水槽３の面との間に、先のシール部材２２に加えてラビリンスシール機構１９を設けたものである。 In the present embodiment, as shown in FIG. 9, a labyrinth seal mechanism is provided between the surface of the rotating tub 5 having the rotation shaft 6 a and the surface of the water tub 3 facing through the air passage 20 in addition to the previous sealing member 22. 19 is provided.
このラビリンスシール機構１９は、前記シール部材２２の内側領域に位置し、前記回転槽５の回転軸６ａと同心円状に設けられている。 The labyrinth seal mechanism 19 is located in the inner region of the seal member 22 and is provided concentrically with the rotary shaft 6a of the rotary tub 5.
これにより、シール部材２２によるシール機能とラビリンスシール機構１９によるシール機能の相乗効果により、より一層シール効果を高めることができ、矢印ｂで示す如く温風をより確実に回転槽５内に導き、より多くの温風を衣類４に接触させ、乾燥性能を向上させることができる。 As a result, the synergistic effect of the sealing function by the sealing member 22 and the sealing function by the labyrinth sealing mechanism 19 can further enhance the sealing effect, and as shown by the arrow b, the hot air is more reliably guided into the rotary tank 5, More warm air can be brought into contact with the garment 4 to improve the drying performance.
なお、前記ラビリンスシール機構１９は、図１０に示す如く、シール部材２２の外側に設けることも可能である。 The labyrinth seal mechanism 19 can also be provided outside the seal member 22 as shown in FIG.
また、上記各実施の形態においては、シール部材２２を送風路２０内の温風による風圧および熱膨張変形を利用してその先端を送風路２０内に突出させる構成としたが、かかる構成に限らず、送風装置２１の運転あるいは乾燥工程への切換え操作に連動してシール部材を突出させる機構手段等を設けてもよい。 Moreover, in each said embodiment, although the sealing member 22 was set as the structure which makes the front-end | tip protrude in the ventilation path 20 using the wind pressure and thermal expansion deformation by the warm air in the ventilation path 20, it is restricted to this structure. Instead, a mechanism unit or the like that projects the seal member in conjunction with the operation of the blower 21 or the switching operation to the drying process may be provided.
以上のように、本発明にかかる洗濯乾燥機は、乾燥工程において衣類の量に影響されることなく安定した温風量を、衣類へ接触させる送風機能を有するため、衣類の量が多い場合でも乾燥性能を確保し、乾燥時間を短縮することができるので、乾燥、除湿を行う洗濯乾燥機さらには、回転槽内で乾燥を行う乾燥装置等に有用である。 As described above, the washing and drying machine according to the present invention has an air blowing function that brings a stable amount of warm air into contact with clothing without being affected by the amount of clothing in the drying process.
