外槽2の下部に温風、洗濯水、除湿水の出口21を設け、この出口21と温風循環経路18とを伸縮自在の下部蛇腹ホース22を介して連結している。温風循環経路18の下部には、排水弁23を介して排水口24を設けている。25は給水弁を含む給水部である。また、温風送風機12の吸気側に吸気弁26を介して吸気口27を設けている。   An outlet 21 for hot air, washing water, and dehumidified water is provided at the lower part of the outer tub 2, and the outlet 21 and the hot air circulation path 18 are connected via a retractable lower bellows hose 22. In the lower part of the hot air circulation path 18, a drain port 24 is provided via a drain valve 23. Reference numeral 25 denotes a water supply unit including a water supply valve. An intake port 27 is provided on the intake side of the hot air blower 12 via an intake valve 26.

温風送風機12により循環する温風(循環風)は、ヒータ13を通り、蛇腹ホース20、吐出口17、内槽7内部、回転翼9に設けた小穴11、内槽7の周辺の小孔(図示せず)、外槽2の下部、外槽2の下部に設けた下部蛇腹ホース22、温風循環経路18を通り、再び温風送風機12へと循環する。このとき、冷却用送風機14により外部から導入した冷風により温風循環経路18を冷却し、循環する高湿温風を除湿する。温度センサ28は外槽2内に設け、循環風の温度を検知するようにしている。内槽7内には、投入された衣類(洗濯物および乾燥対象物)29が入っている。   Hot air (circulated air) circulated by the hot air blower 12 passes through the heater 13, the bellows hose 20, the discharge port 17, the inner tank 7, the small holes 11 provided in the rotary blade 9, and the small holes around the inner tank 7. (Not shown), passes through the lower bellows hose 22 provided in the lower part of the outer tub 2, the lower part of the outer tub 2, and the hot air circulation path 18, and then circulates again to the hot air blower 12. At this time, the hot air circulation path 18 is cooled by the cold air introduced from the outside by the cooling blower 14, and the circulating high-humidity hot air is dehumidified. The temperature sensor 28 is provided in the outer tub 2 so as to detect the temperature of the circulating air. The inner tub 7 contains the clothes (laundry and drying objects) 29 that have been thrown in.

表示部30は制御部31に接続しており、制御部31は、マイクロコンピュータを具備し、モータ4、温風送風機12、ヒータ13、冷却用送風機14、排水弁23、吸気弁26などの動作を制御し、洗い、すすぎ、脱水、乾燥の各行程を逐次制御するように構成している。   The display unit 30 is connected to the control unit 31, and the control unit 31 includes a microcomputer and operates the motor 4, the hot air blower 12, the heater 13, the cooling blower 14, the drain valve 23, the intake valve 26, and the like. And the steps of washing, rinsing, dewatering and drying are sequentially controlled.

また、制御部31は、乾燥行程において、図8に示すように、衣類29が内槽7の壁面に沿って内槽7の上方にせり上がり、回転中心部で回転翼9が見え出す程度の所定の回転数(たとえば、180r/min)で回転させる行程を有している。   Further, as shown in FIG. 8, in the drying process, the control unit 31 raises the clothes 29 so as to rise above the inner tub 7 along the wall surface of the inner tub 7, and the rotating blades 9 can be seen at the center of rotation. It has a process of rotating at a predetermined rotational speed (for example, 180 r / min).

上記構成においての動作を説明する。洗濯・すすぎ行程では、表示部30に従い、制御部31の制御により、排水弁23を閉じた状態で、内槽7内に衣類29と洗剤を投入し、給水部25により水または湯を給水し、伝達機構部のクラッチ6の切り換えにより、モータ4の動力を洗濯・脱水軸5を介して、内槽7または回転翼9に伝達し、内槽7または回転翼9が回転することで、衣類29に洗剤を含む水分を通過させたり、衣類29を洗剤を含む水中で撹拌して洗濯・すすぎを行う。   The operation in the above configuration will be described. In the washing and rinsing process, according to the display unit 30, the control unit 31 controls the clothes valve 29 and the detergent into the inner tub 7 with the drain valve 23 closed, and the water supply unit 25 supplies water or hot water. By switching the clutch 6 of the transmission mechanism section, the power of the motor 4 is transmitted to the inner tub 7 or the rotary wing 9 via the washing / dehydrating shaft 5, and the inner tub 7 or the rotary wing 9 rotates, so that the clothes Washing and rinsing are performed by passing moisture containing detergent through 29 or stirring the clothes 29 in water containing detergent.

脱水行程では、洗濯・すすぎ行程終了後、制御部31により排水弁23を開いて、内槽7内の水を排水口24から外部へ排水した後、伝達機構部のクラッチ6を脱水側に切り換えて、モータ4の動力を洗濯・脱水軸5を介し内槽7に伝達して徐々に回転を上げて、800r/min程度の回転数で回転させ、衣類29に遠心力を与えることにより、水分を衣類29から分離し、排水弁23、排水口24を通過して外部へ排水する。   In the dehydration process, after the washing / rinsing process is completed, the control unit 31 opens the drain valve 23 to drain the water in the inner tub 7 from the drain port 24 to the outside, and then switches the clutch 6 of the transmission mechanism unit to the dehydration side. Then, the motive power of the motor 4 is transmitted to the inner tub 7 through the washing / dehydrating shaft 5 to gradually increase the rotation speed, rotate at a rotation speed of about 800 r / min, and apply centrifugal force to the clothing 29 to obtain moisture. Is separated from the garment 29, passes through the drain valve 23 and the drain port 24, and drains to the outside.

乾燥行程では、同様に制御部31により、まず、排水弁23を閉じた上、回転翼9をゆっくり正逆に回転させることにより、脱水行程における内槽7の回転による遠心力で内槽7の内壁に張り付いた衣類29を引き剥がす衣類剥がし行程の後、内槽7の回転数を所定の回転数(180r/min)程度まで上げて、衣類29を内槽7の内壁に沿って上方へせり上げる。   Similarly, in the drying process, the controller 31 first closes the drain valve 23 and slowly rotates the rotor blades 9 in the forward and reverse directions, so that the centrifugal force generated by the rotation of the inner tank 7 in the dehydration process causes the inner tank 7 to rotate. After the garment peeling process for peeling off the garment 29 attached to the inner wall, the rotational speed of the inner tub 7 is increased to a predetermined rotational speed (180 r / min), and the garment 29 is moved upward along the inner wall of the inner tub 7. Raise it.

このとき、温風は、吐出口17、内槽7の内部にある衣類29の表面をなぞって、回転翼9の小穴11、および一部は内槽7の内壁に設けた小孔(図示せず)を通過して外槽2の内部へと内槽7内でよどむことなく流れ、その後、外槽2の下部の出口21へ移る。   At this time, the warm air traces the surface of the garment 29 inside the discharge port 17 and the inner tub 7, and the small holes 11 of the rotor blades 9, and some of the small holes (not shown) provided in the inner wall of the inner tub 7. )) To the inside of the outer tub 2 without stagnation in the inner tub 7, and then to the outlet 21 at the bottom of the outer tub 2.

この内槽7内を通過するとき、衣類29の表面に当たるときに衣類に含まれる水分を取って温風循環経路18へと流れ込み、ここで冷却用送風機14による外部の空気によって冷やされて除湿される。除湿された水分は、温風循環経路18の下部に集まり、排水弁23が開かれたときに排水口24から外部へ排水される。   When passing through the inner tub 7, when it hits the surface of the clothing 29, it takes moisture contained in the clothing and flows into the warm air circulation path 18, where it is cooled and dehumidified by the external air by the cooling fan 14. The The dehumidified water collects in the lower part of the warm air circulation path 18 and is drained to the outside from the drain port 24 when the drain valve 23 is opened.

この状態を数分つづけた後、図7に示すように、回転翼9を正逆に数回回転させ、その後、再度内槽7を所定の回転数で回転させる行程へ戻り、この動作を繰り返し行う。   After continuing this state for several minutes, as shown in FIG. 7, the rotor blade 9 is rotated several times forward and backward, and then the process returns to the process of rotating the inner tank 7 again at a predetermined rotational speed, and this operation is repeated. Do.

なお、この乾燥行程には、温風送風機12の吸気側に設けている吸気弁26を開けて、吸気口27から外気を内槽7内部に導入するように設定する(例えば、特許文献1参照)。

ヒータ42を動作させないコースは、図3に示すように、内槽7の回転により自然風が発生する回転数(例えば、700r/min)で内槽7を回転させ、かつヒータ42に通電しない状態で乾燥用送風機40により内槽7に送風する第1の行程を有している。この第1の行程を乾燥行程の初期に所定時間(T1)(例えば、乾燥行程の2/5)行うようにしている。   As shown in FIG. 3, the course in which the heater 42 is not operated is a state in which the inner tub 7 is rotated at a rotation speed (for example, 700 r / min) generated by the rotation of the inner tub 7 and the heater 42 is not energized. The first step of blowing air to the inner tank 7 by the blower 40 for drying is provided. The first stroke is performed for a predetermined time (T1) (for example, 2/5 of the drying stroke) at the beginning of the drying stroke.

また、ヒータ42を間欠動作させるコースは、図4に示すように、内槽7の回転により自然風が発生する回転数(例えば、700r/min)で内槽7を回転させ、乾燥用送風機40により内槽7に送風する第1の行程の初期に、ヒータ42によって加熱した温風を送風するようにしている。   Further, in the course of intermittently operating the heater 42, as shown in FIG. 4, the inner tub 7 is rotated at a rotation speed (for example, 700 r / min) at which natural wind is generated by the rotation of the inner tub 7, and the drying fan 40 Thus, the warm air heated by the heater 42 is blown at the initial stage of the first step of blowing air to the inner tank 7.

また、ヒータ42を連続動作させるコースは、図5に示すように、内槽7の回転により自然風が発生する回転数(例えば、700r/min)で内槽7を回転させ、乾燥用送風機40により内槽7に送風する第1の行程にて、ヒータ42を連続動作させ、ヒータ42によって加熱した温風を送風するようにしている。   Further, as shown in FIG. 5, the course in which the heater 42 is continuously operated rotates the inner tub 7 at a rotation speed (for example, 700 r / min) at which natural wind is generated by the rotation of the inner tub 7, and the blower 40 for drying. Thus, the heater 42 is continuously operated in the first step of blowing air to the inner tank 7 so that warm air heated by the heater 42 is blown.

上記構成において、操作スイッチ51によりヒータ42を動作させないコースに設定した場合の動作を説明する。洗い行程では、蓋体37と内蓋35を開けて、内槽7に衣類を投入し運転を開始すると、給水弁39が開き、外槽カバー32に接続された給水蛇腹ホース47を通して所定の水位まで給水した後、モータ4を駆動する。伝達機構部のクラッチ6によりモータ4の動力が洗濯軸49を介して回転翼9に伝達されて駆動し、撹拌ブレード10により衣類を撹拌し、衣類どうしまたは内槽7や回転翼9との接触により作用する機械力と水流により衣類の洗浄が行われる。   In the above configuration, the operation when the operation switch 51 is set to a course in which the heater 42 is not operated will be described. In the washing process, when the lid 37 and the inner lid 35 are opened, clothes are put into the inner tub 7 and the operation is started, the water supply valve 39 is opened and a predetermined water level is passed through the water supply bellows hose 47 connected to the outer tub cover 32. After the water is supplied, the motor 4 is driven. The power of the motor 4 is transmitted to the rotary blade 9 via the washing shaft 49 and driven by the clutch 6 of the transmission mechanism, and the clothes are agitated by the agitating blade 10, and the clothes are in contact with each other or the inner tub 7 and the rotary blade 9. The clothes are washed by the mechanical force and the water flow acting by.

脱水行程では、洗濯終了後、排水弁48を開いて内槽7内の水を排水した後、クラッチ6を脱水側に切り換えて、モータ4の動力を脱水軸50に伝達して内槽7を駆動し、遠心力により衣類から水分を分離させる。   In the dehydration process, after washing is completed, the drain valve 48 is opened to drain the water in the inner tub 7, the clutch 6 is switched to the dehydration side, and the power of the motor 4 is transmitted to the dehydration shaft 50 so that the inner tub 7 is removed. Drives and separates moisture from clothing by centrifugal force.

乾燥行程では、第1の行程として、脱水終了後、排水弁48を閉じ、クラッチ6を脱水側のまま、モータ4の回転を内槽7に伝達し、内槽7の回転により自然風が発生する回転数(例えば、700r/min)で内槽7を回転させる。衣類は脱水行程後の内槽7の内壁に張り付いたまま、または、衣類を投入し乾燥行程からの場合は内槽7の内壁に沿って上方へせり上がり、内槽7の内壁に分散し、ほぼ均等配置した状態となる。   In the drying process, as the first process, after the dehydration is completed, the drain valve 48 is closed, the rotation of the motor 4 is transmitted to the inner tank 7 while the clutch 6 is kept on the dehydrating side, and natural wind is generated by the rotation of the inner tank 7. The inner tank 7 is rotated at a rotating speed (for example, 700 r / min). Clothes remain attached to the inner wall of the inner tub 7 after the dehydration process, or, when clothes are put in and from the drying process, the clothes rise upward along the inner wall of the inner tub 7 and are dispersed on the inner wall of the inner tub 7. , Almost evenly arranged.

このとき、自然風は内槽7の中心上方から下方へ引き込まれ、乾燥用送風機40から送風された相対湿度が低い風とともに、内槽7の回転による遠心力で内槽7の中心から内槽7内壁に分散された衣類の間を通過し、内槽7の小孔を通過し、外槽2の内壁を沿って上方に流れ、内槽7の上方の排気フィルター44から排出される。   At this time, the natural wind is drawn downward from the upper center of the inner tub 7, and with the low relative humidity blown from the drying blower 40, the centrifugal force generated by the rotation of the inner tub 7 causes the inner tub 7 to move from the center of the inner tub 7. 7 passes between clothes distributed on the inner wall, passes through a small hole in the inner tub 7, flows upward along the inner wall of the outer tub 2, and is discharged from an exhaust filter 44 above the inner tub 7.

この自然風と乾燥用送風機40から送風された相対湿度が低い風は、衣類の間を均等に通過することができ、ヒータ42によって加熱した温風を供給することなく衣類から水分を蒸発させ、乾燥を進行することができる。   The natural wind and the low relative humidity blown from the drying blower 40 can pass between the clothes evenly, evaporate the moisture from the clothes without supplying warm air heated by the heater 42, Drying can proceed.

その後、図2に示すように、第2の行程として、ヒータ42に通電しない状態で、回転翼9を正逆に回転させることで内槽7の内壁に張り付いた衣類を引き剥がし、回転翼9を正逆に回転と内槽7の低い回転数(例えば、35r/min)の繰り返す行程を所定時間(T2−T1)行い、その後、第3の行程として、ヒータ42に通電しない状態で、回転翼9を正逆に回転の連続の行程を所定時間(T3−T2)行うことで、化繊などの水分を含みにくい衣類はしわを付けることなく、少ない消費電力量で乾燥することができる。ここで、第2の行程と第3の行程は衣類の種類や量によっては、なくてもよいものである。   Thereafter, as shown in FIG. 2, as a second step, without rotating the heater 42, the rotating blades 9 are rotated in the forward and reverse directions to peel off the clothes attached to the inner wall of the inner tub 7. No. 9 is rotated forward and backward, and a process of repeating a low rotation speed (for example, 35 r / min) of the inner tub 7 is performed for a predetermined time (T2-T1). Thereafter, as a third process, the heater 42 is not energized, By performing a continuous process of rotating the rotor blades 9 forward and backward for a predetermined time (T3-T2), clothes that do not contain moisture such as synthetic fibers can be dried with less power consumption without wrinkling. Here, the second process and the third process may be omitted depending on the type and amount of clothing.

これにより、ヒータ42を動作させないコースでは、ブラウス、ワイシャツ、ジャージ等の化繊などの水分を含みにくい衣類をしわをつけることなく、少ない消費電力量で乾燥することができ、また、水着、ブラウス等の熱に弱い衣類を乾燥することができる。   As a result, in courses where the heater 42 is not operated, clothes that are difficult to contain moisture such as blouse, shirts, jerseys and the like can be dried with less power consumption without wrinkling, and swimwear, blouse, etc. Can dry clothes that are vulnerable to heat.

つぎに、ヒータ42を間欠動作させるコースを設定した場合の動作を説明する。なお、洗い行程から脱水行程までの動作は上述した動作と同じであるので説明を省略する。   Next, an operation when a course for intermittently operating the heater 42 is set will be described. Since the operation from the washing process to the dehydration process is the same as the above-described operation, the description thereof is omitted.

乾燥行程の第1の行程にて、内槽7の回転により自然風が発生する回転数で内槽7を回転させ、乾燥用送風機40から送風する行程の初期に、所定時間(T4)ヒータ42によって加熱した温風を送風することにより、衣類から水分を蒸発させ、さらに外槽2と内槽7と衣類が暖められる。その後、ヒータ42による加熱を停止しても、外槽2と内槽7と衣類の余熱により、より効果的に衣類から水分を蒸発させ、乾燥が進行する。   In the first step of the drying process, the inner tank 7 is rotated at a rotation speed at which natural wind is generated by the rotation of the inner tank 7, and the heater 42 is provided for a predetermined time (T4) at the beginning of the process of blowing air from the drying blower 40. By blowing the warm air heated by the air, moisture is evaporated from the clothing, and the outer tub 2, the inner tub 7 and the clothing are warmed. Thereafter, even if heating by the heater 42 is stopped, moisture is more effectively evaporated from the clothing by the residual heat of the outer tub 2, the inner tub 7, and the clothing, and drying proceeds.

このように第1の行程の内槽7を回転させている初期にヒータ42を加熱し、その後、加熱を停止することで、衣類の乾燥速度が速くなり、乾燥時間を短縮し、少ない消費電力量で、衣類を乾燥することができ、しわも低減できる。   Thus, by heating the heater 42 in the initial stage of rotating the inner tank 7 in the first stroke and then stopping the heating, the drying speed of the clothes is increased, the drying time is shortened, and the power consumption is reduced. By quantity, the clothes can be dried and wrinkles can be reduced.

ここで、第1の行程の初期に、ヒータ42によって加熱した温風を送風する構成としているが、ヒータ42による加熱を停止した後、さらに、間欠的にヒータ42によって加熱してもよく、同様の作用効果を得ることができる。また、第2の行程および第3の行程では、ヒータ42に通電してもしなくてもよい。   Here, in the initial stage of the first stroke, the warm air heated by the heater 42 is blown. However, after the heating by the heater 42 is stopped, the heating may be intermittently performed by the heater 42. The effect of this can be obtained. Further, the heater 42 may or may not be energized in the second stroke and the third stroke.

これにより、ヒータ42を間欠動作させるコースでは、ヒータ42を連続動作させるコースと比べ、乾燥時間は長くなるが、少ない消費電力量で乾燥することができる。   Thereby, in the course in which the heater 42 is intermittently operated, the drying time is longer than in the course in which the heater 42 is continuously operated, but the drying can be performed with a small amount of power consumption.

つぎに、ヒータ42を連続動作させるコースを設定した場合の動作を説明する。なお、洗い行程から脱水行程までの動作は上述した動作と同じであるので説明を省略する。   Next, an operation when a course for continuously operating the heater 42 is set will be described. Since the operation from the washing process to the dehydration process is the same as the above-described operation, the description thereof is omitted.

乾燥行程の第1の行程にて、内槽7の回転により自然風が発生する回転数で内槽7を回転させ、ヒータ42によって加熱した温風を送風するとともに、つづく第2の行程および第3の行程のすべてにて、ヒータ42を動作させ、温風を送風し続けることで、効率よく衣類の乾燥を行うことができる。   In the first step of the drying step, the inner tub 7 is rotated at a rotation speed at which natural wind is generated by the rotation of the inner tub 7, and the warm air heated by the heater 42 is blown. In all of the steps 3, the heater 42 is operated and the hot air is continuously blown, whereby the clothes can be efficiently dried.

このように第1の行程から、ヒータ42を連続動作させるようにしたので、ヒータ42により加熱した温風を連続供給することで、乾燥効率を向上することができ、同じ量の衣類であれば、乾燥時間を短縮することができる。また、同じ乾燥時間であれば、より多くの衣類を乾燥することができる。   As described above, since the heater 42 is continuously operated from the first step, the drying efficiency can be improved by continuously supplying the warm air heated by the heater 42. , Drying time can be shortened. Further, more clothes can be dried with the same drying time.

以上のように、本実施の形態においては、3つのコース、すなわち、加熱手段を動作させないコースと、加熱手段を間欠動作させるコースと、加熱手段を連続動作させるコースを制御するようにしたので、これら3つのコースを適宜選択することにより、衣類の種類や量によって傷んだり、しわになったりするのを防止し、乾燥時間と消費電力量のいずれを優先させるか、または両方をある程度優先させるかを選択することができ、使用者にあった仕上がりやランニングコストを実現することができる。   As described above, in the present embodiment, the three courses are controlled, that is, the course in which the heating means is not operated, the course in which the heating means is intermittently operated, and the course in which the heating means is continuously operated. By selecting these three courses as appropriate, it is possible to prevent damage and wrinkles depending on the type and amount of clothing, and give priority to either drying time and power consumption or to some extent both. Can be selected, and the finish and running cost suitable for the user can be realized.

また、ヒータ42を動作させないコースと、ヒータ42を間欠動作させるコースと、ヒータ42を連続動作させるコースとを一つの操作スイッチ51で切り換え設定できるようにしたので、一つの操作スイッチ51の切り換え操作で、3つのコースを適宜設定することができ、乾燥時間と消費電力量のいずれを優先させるか、または両方をある程度優先させるかを選択して設定することができ、使用者にあった仕上がりやランニングコストを実現することができる。   In addition, since the course for not operating the heater 42, the course for intermittently operating the heater 42, and the course for continuously operating the heater 42 can be set by one operation switch 51, the switching operation of one operation switch 51 can be performed. The three courses can be set as appropriate, and it can be set by selecting which of the drying time and power consumption is prioritized or which is prioritized to some extent. Running costs can be realized.

(実施の形態2)
図1に示す操作表示手段38は、図6に示すように、一つの操作スイッチ53でヒータ42を連続動作させるコースと、ヒータ42を間欠動作させるコースとを切り換え設定し、別の操作スイッチ54でヒータ42を動作させないコースを設定できるよう構成している。他の構成は上記実施の形態1と同じである。
(Embodiment 2)
As shown in FIG. 6, the operation display means 38 shown in FIG. 1 switches between a course in which the heater 42 is continuously operated by one operation switch 53 and a course in which the heater 42 is intermittently operated, and another operation switch 54 is set. In this way, a course in which the heater 42 is not operated can be set. Other configurations are the same as those of the first embodiment.

上記構成において作用を説明する。操作表示手段38は、ヒータ42を連続動作させるコースとヒータ42を間欠動作させるコースとを一つの操作スイッチ53で切り換え設定し、ヒータ42を動作させないコースを別の操作スイッチ54で設定するようにしたので、ヒータ42を動作させないコースを別の操作スイッチ54で設定することにより、ヒータ42を動作させるかどうかをより明確に認識でき、そして、使用者が複数の乾燥パターンを選択でき、使用者にあった仕上がりやランニングコストを実現することができる。   The operation of the above configuration will be described. The operation display means 38 switches between a course for continuously operating the heater 42 and a course for intermittently operating the heater 42 by one operation switch 53, and sets a course for not operating the heater 42 by another operation switch 54. Therefore, by setting a course in which the heater 42 is not operated with another operation switch 54, it is possible to more clearly recognize whether or not the heater 42 is operated, and the user can select a plurality of drying patterns. The finish and running cost can be realized.

以上のように、本発明にかかる洗濯乾燥機は、乾燥行程にて、衣類の種類や量によって傷んだり、しわになったりするのを防止し、乾燥時間と消費電力量のいずれを優先させるか、または両方をある程度優先させるかを選択することができ、使用者にあった仕上がりやランニングコストを実現することができるので、洗濯物を乾燥させる行程を有する洗濯乾燥機として有用である。   As described above, the washing / drying machine according to the present invention prevents the clothes from being damaged or wrinkled by the type and amount of clothes in the drying process, and gives priority to either the drying time or the power consumption. It is possible to select whether or not both are given priority to some extent, and a finish and running cost suitable for the user can be realized. Therefore, the present invention is useful as a laundry dryer having a process of drying laundry.
