Description

本発明は、洗濯機および洗濯乾燥機に関する。   The present invention relates to a washing machine and a washing / drying machine.

全自動洗濯機は、洗濯兼脱水槽に投入された洗濯衣類の量を検出し、洗濯物（洗濯衣類）の量に相応した量の洗剤を投入し、洗い工程においては、洗濯衣類の量に応じた量の水道水（洗い水）を給水後に、撹拌翼を正逆回転させ、または洗濯兼脱水槽を一方向に回転、または正逆回転させて洗濯衣類に機械力を作用させる洗い工程を実行し、その後、水道水（濯ぎ水）を給水すると共に洗濯衣類に同様に機械力を作用させる濯ぎ工程を実行し、その後、洗濯兼脱水槽を回転させることにより洗濯衣類に含まれる濯ぎ水を遠心脱水する脱水工程を実行する構成である。洗濯衣類の乾燥まで行う洗濯乾燥機では、更にその後に、温風を吹き込んで乾燥させる温風乾燥工程を実行する構成である。   The fully automatic washing machine detects the amount of laundry put into the washing and dewatering tub, and puts in an amount of detergent corresponding to the amount of laundry (laundry clothing). After supplying the appropriate amount of tap water (washing water), the washing process in which the stirring blade is rotated forward and reverse, or the washing and dewatering tub is rotated in one direction, or rotated forward and reverse to apply mechanical force to the laundry clothes. After that, a rinsing step of supplying tap water (rinsing water) and applying a mechanical force to the laundry as well is performed, and then rotating the washing and dewatering tub to remove the rinsing water contained in the laundry. This is a configuration for performing a dehydration step of performing centrifugal dehydration. The washing / drying machine that performs the drying of the laundry clothes is configured to further execute a hot air drying step of blowing hot air to dry the washing clothes.

このような全自動洗濯機や洗濯乾燥機において、洗い工程において洗い水に溶解させる合成洗剤の量は、一般的に２０ｇ／３０Ｌ（洗剤量／洗い水量）程度であり、洗い水の洗剤濃度は、０．０７％程度である。   In such fully automatic washing machines and washing / drying machines, the amount of the synthetic detergent dissolved in the washing water in the washing step is generally about 20 g / 30 L (detergent amount / washing water amount), and the detergent concentration of the washing water is , About 0.07%.

このような洗剤濃度の洗い水で洗いを行う場合、洗剤の化学的な洗浄力はあまり大きくないため、洗濯衣類に付着した汚れを除去するためには、洗濯機の撹拌翼または洗濯兼脱水槽の回転力を強くしたり、洗い時間を長くしたりすることにより、洗濯衣類に作用させる機械力を強くしなければならない。その結果、機械力による洗濯衣類の傷みが激しくなったり、洗濯衣類の絡みが多くなったりする欠点があるのが現状である。   When washing with washing water having such a detergent concentration, the chemical detergency of the detergent is not so large. Therefore, in order to remove dirt adhering to laundry clothes, a stirring blade of a washing machine or a washing and dewatering tub is required. The mechanical force applied to the laundry should be increased by increasing the rotational force of the garment and increasing the washing time. As a result, at present, there is a drawback that the laundry is severely damaged by mechanical force and the laundry is entangled.

そして、洗濯衣類の絡みが多くなると、洗いむらが多くなり、洗濯衣類の取り出しが困難になる。また、洗濯乾燥機においては、洗濯兼脱水槽内での温風乾燥が、乾燥むら等の発生により困難になったり、洗濯衣類がしわだらけになったりする。温風乾燥を行うためには洗濯衣類に作用させる機械力を小さくし、布からみを少なくすることが必要になり、その結果、汚れ落ちが悪くなる欠点が発生している。   When the entanglement of the laundry is increased, the unevenness of washing is increased, and it becomes difficult to take out the laundry. In a washing and drying machine, hot air drying in a washing and dewatering tub becomes difficult due to occurrence of uneven drying and the like, and laundry becomes wrinkled. In order to carry out hot-air drying, it is necessary to reduce the mechanical force acting on the laundry and reduce the amount of entanglement of the cloth, and as a result, there is a disadvantage in that the stains are not easily removed.

洗い工程において洗濯衣類に作用させる機械力を軽減するために、例えば特開平７−８０１８２号公報には、洗い工程前に洗濯衣類を高濃度洗剤液に浸しておく予浸工程を追加することによって高濃度洗剤による化学的な洗浄力を活用する全自動洗濯機が開示されている。   In order to reduce the mechanical force acting on the laundry in the washing process, for example, Japanese Patent Application Laid-Open No. 7-80182 discloses a method of adding a pre-soaking process in which laundry is soaked in a high-concentration detergent solution before the washing process. A fully automatic washing machine that utilizes the chemical detergency of a highly concentrated detergent has been disclosed.

特開平７−８０１８２号公報JP-A-7-80182

洗濯機や洗濯乾燥機は、洗濯、脱水および乾燥を実行するための手段を、限られた形態の筐体（横幅、奥行き、背丈）内に収納することができるように構成することが望ましい。特に、洗剤の化学的な洗浄力を有効に発揮させるために、高濃度の洗剤液を生成して洗濯物に浸透させるための手段は、従来の洗濯機や洗濯乾燥機に追加される新しい手段であり、これらの手段を筐体内に合理的に設置して実用的な洗濯機や洗濯乾燥機を実現するための工夫が必要である。特開平７−８０１８２号公報には、洗濯物重量の倍の水で洗剤を溶解して高濃度洗剤液を生成することが例示されているが、これは、例えば、４ｋｇの洗濯物の洗濯においては、８Ｌの高濃度洗剤液が必要となり、このような多量の高濃度洗剤液を生成して蓄積する手段を設置するためには大きな筐体が必要になる。   It is desirable that the washing machine and the washer / dryer be configured such that means for performing washing, dehydration, and drying can be accommodated in a limited-form housing (width, depth, height). In particular, in order to effectively exert the chemical detergency of the detergent, a means for generating a high concentration of detergent liquid and infiltrating the laundry is a new means added to conventional washing machines and washing and drying machines. Therefore, it is necessary to devise these means in a housing to realize a practical washing machine and washing / drying machine. Japanese Patent Application Laid-Open No. 7-80182 exemplifies that a detergent is dissolved in water twice the weight of the laundry to produce a high-concentration detergent solution. Requires an 8 L high-concentration detergent solution, and a large housing is required to install means for generating and storing such a large amount of high-concentration detergent solution.

本発明の１つの目的は、洗剤を使用して該洗剤の化学的な洗浄力を効果的に発揮せることにより、洗い工程において洗濯物（洗濯衣類）に作用させる機械力を大幅に軽減することができる実用的な洗濯機を提案することにある。   One object of the present invention is to significantly reduce the mechanical force acting on laundry (laundry clothes) in a washing process by effectively using a detergent to exert the chemical detergency of the detergent. It is to propose a practical washing machine that can do the work.

本発明の他の目的は、洗濯兼脱水槽内で脱水した洗濯物を該洗濯兼脱水槽に温風を吹き込むことによって乾燥させる洗濯機において、洗い工程において洗濯物に作用させる機械力を軽減することにより、汚れ落ちを悪化させることなく洗濯兼脱水槽内の洗濯物の絡みを軽減して乾燥効率を向上させ、乾燥むらを軽減することにある。
本発明の更に他の目的は、粉末合成洗剤を溶解および希釈して洗濯物に散布する高濃度洗剤液によって洗濯物に色むらが発生するのを防止することにある。 Another object of the present invention is to reduce the mechanical force applied to the laundry in the washing process in a washing machine for drying the laundry dehydrated in the washing and dehydrating tub by blowing hot air into the washing and dehydrating tub. Thus, it is possible to reduce the entanglement of the laundry in the washing and dewatering tub without deteriorating the stain removal, improve the drying efficiency, and reduce the uneven drying.
It is still another object of the present invention to prevent the washing of the laundry by dissolving and diluting the powdered synthetic detergent and dispersing the laundry into the laundry, thereby preventing the washing agent from becoming uneven in color.

本発明は、洗剤を少量の洗剤溶解水に溶解して洗い水の洗剤濃度よりも高濃度の高濃度洗剤液を生成し、この高濃度洗剤液を希釈しながら洗濯物に散布して浸透させることにより、洗濯物に付着している汚れに作用する洗剤の化学的な洗浄力を利用して洗浄効率を高め、その後の洗いにおいて洗濯物に作用させる機械力を軽減するものである。   According to the present invention, a detergent is dissolved in a small amount of detergent-dissolved water to generate a high-concentration detergent solution having a higher concentration than the detergent concentration of the wash water. Thereby, the cleaning efficiency is enhanced by using the chemical detergency of the detergent acting on the dirt attached to the laundry, and the mechanical force acting on the laundry in the subsequent washing is reduced.

また、洗濯物に散布して浸透させる洗剤液の濃度は、粉末合成洗剤を水道水で溶解および希釈することによって該水道水に含まれる硬度成分により有効な界面活性剤の量が減少するのを該洗剤に含まれる軟水化剤の機能によって効果的に抑制することができる程度に制御する。   In addition, the concentration of the detergent liquid that is sprayed and impregnated on the laundry is determined by dissolving and diluting the powdered synthetic detergent with tap water so that the amount of the effective surfactant is reduced by the hardness component contained in the tap water. It is controlled to such an extent that it can be effectively suppressed by the function of the water softener contained in the detergent.

本発明は、洗剤を少量の洗剤溶解水に溶解して高濃度洗剤液（例えば洗い水の洗剤濃度の８０〜５００倍）を生成し、この高濃度洗剤液を希釈（例えば洗い水の洗剤濃度の５〜２０倍）しながら洗濯物に散布し浸透させることにより、洗剤の化学的な洗浄力を効果的に発揮させることができ、洗い工程において洗濯物に作用させる機械力を効果的に軽減することができる。
また、本発明は、洗濯兼脱水槽内で脱水した洗濯物を該洗濯兼脱水槽に温風を吹き込むことによって乾燥させる洗濯機においては、洗濯物の絡みを軽減することにより乾燥むらを軽減することができる。 In the present invention, a detergent is dissolved in a small amount of detergent-dissolved water to produce a high-concentration detergent solution (for example, 80 to 500 times the detergent concentration of the wash water), and the high-concentration detergent solution is diluted (for example, the detergent concentration of the wash water). (5 to 20 times the size of the detergent) while spraying and penetrating the laundry, the chemical detergency of the detergent can be effectively exerted, and the mechanical force acting on the laundry in the washing process can be effectively reduced. can do.
The present invention also provides a washing machine for drying laundry that has been dehydrated in a washing and dewatering tub by blowing warm air into the washing and dehydrating tub, thereby reducing uneven drying by reducing entanglement of the laundry. be able to.

また、本発明は、洗濯物の検出量に応じて設定した量の洗剤を少量の洗剤溶解水で溶解して高濃度洗剤液を生成し、これを希釈しながら洗濯物に降りかけて浸透させるようにしたので、洗いに好適な量の洗剤を効率良く使用して小型の洗剤溶解容器によって浸透に好ましい高濃度洗剤液と好ましい洗剤濃度の洗い水を生成することができる。   The present invention also provides a high-concentration detergent solution by dissolving a set amount of detergent in a small amount of detergent-dissolving water in accordance with the detected amount of laundry, and dilutes the detergent solution to descend and permeate the laundry. With this configuration, it is possible to efficiently use a suitable amount of detergent for washing, and to generate a high-concentration detergent solution suitable for permeation and washing water having a preferred detergent concentration by a small-sized detergent dissolving vessel.

また、本発明は、攪拌翼を洗濯兼脱水槽に対して相対運動させて洗濯物を回転または撹拌しながら高濃度洗剤液を洗濯物に散布することにより、高濃度洗剤液を洗濯物に均一に散布することができる。   In addition, the present invention also applies a high-concentration detergent solution to the laundry by rotating or stirring the laundry while rotating the stirring blade relative to the washing / dewatering tub to spray the high-concentration detergent solution on the laundry. Can be sprayed.

粉末合成洗剤を少量の洗剤溶解水で溶解することによって高濃度洗剤液を生成し、この高濃度洗剤液を洗濯物に浸透させることにより、洗濯物に付着している汚れに高濃度洗剤液の化学的な洗浄力が作用して洗浄作用が発生することから、その後の洗いにおいて洗濯物に作用させる機械力を軽減することができる。化学的な洗浄作用は、洗濯物に浸透させる高濃度洗剤液の濃度の影響を受ける。   A high-concentration detergent solution is generated by dissolving the powdered synthetic detergent with a small amount of detergent-dissolving water, and the high-concentration detergent solution is penetrated into the laundry to remove the high-concentration detergent solution from the dirt attached to the laundry. Since the cleaning action is generated by the action of the chemical detergency, the mechanical force applied to the laundry in the subsequent washing can be reduced. The chemical cleaning action is affected by the concentration of the highly concentrated detergent liquid that penetrates the laundry.

洗いに使用する粉末合成洗剤の量は、洗濯物の量に応じて調整されることから、好ましい化学的洗浄力を発生する好適な高濃度洗剤液を生成するためには、この洗剤の量に応じて給水量を調整することが望ましい。具体的には、洗濯物に浸透させる高濃度洗剤液の望ましい洗剤濃度は、洗い水の標準的な洗剤濃度の５〜２０倍であって、好ましい洗剤濃度は、１０倍程度である。例えば、１０倍の洗剤濃度の高濃度洗剤液は、一般的な洗濯機および洗濯乾燥機において、６０Ｌの洗い水を使用する洗濯では、６Ｌの水で粉末合成洗剤を溶解することによって得られる洗剤液に相当することから、このような大きな容積の洗剤溶解容器を使用することは該洗剤溶解容器の設置場所の観点から好ましいことではなく、従って、粉末合成洗剤を水道水で溶解して生成する高濃度洗剤液は、粉末合成洗剤を溶解するために必要な少ない量、例えば２００〜３００ｍＬの水道水によって洗濯物に浸透させる高濃度洗剤液よりも更に高濃度状態、例えば洗い水の洗剤濃度の２００〜３００倍の濃度に生成し、これを好ましい洗剤濃度に希釈しながら洗濯物に降りかけて浸透させるように構成する。   Since the amount of the powdered synthetic detergent used for washing is adjusted according to the amount of the laundry, in order to generate a suitable high-concentration detergent solution that generates a preferable chemical detergency, the amount of the detergent is reduced. It is desirable to adjust the amount of water supply accordingly. Specifically, a desirable detergent concentration of the high-concentration detergent solution to be permeated into the laundry is 5 to 20 times the standard detergent concentration of the washing water, and a preferred detergent concentration is about 10 times. For example, a high-concentration detergent solution having a detergent concentration of 10 times is used in a general washing machine and a washer / dryer to obtain a detergent obtained by dissolving a powder synthetic detergent with 6 L of water in washing using 60 L of washing water. It is not preferable to use such a large-volume detergent dissolving container from the viewpoint of the installation location of the detergent dissolving container because it corresponds to a liquid, and therefore, the powder synthetic detergent is produced by dissolving in a tap water. The high-concentration detergent solution has a smaller amount necessary to dissolve the powdered synthetic detergent, for example, a higher-concentration state than a high-concentration detergent solution that is permeated into laundry with 200 to 300 mL of tap water, for example, the detergent concentration of the wash water. It is formed so as to have a concentration of 200 to 300 times, which is diluted to a preferable detergent concentration and is allowed to descend and permeate the laundry.

また、蛍光増白剤が含まれる粉末合成洗剤で、生成りや淡色の天然素材の洗濯物を洗うと変色（色むら）が発生する。蛍光増白剤が薄黄色の布に付着し、青紫の光（中心波長４４０ｎｍ）が反射光に加わると、増白され、色が白くなったように見える。色むらは、洗濯物に対する高濃度洗剤液の浸透むらがあると顕著になる。従って、高濃度洗剤液の散布前に、予め少量の水を洗濯物にかて濡らした後に洗濯物を低速回転させながら高濃度洗剤液を散布することによって均一に浸透させるようにすることが望ましい。   In addition, when a laundry made of a light-colored natural material is washed with a powdered synthetic detergent containing a fluorescent whitening agent, discoloration (uneven color) occurs. When the fluorescent whitening agent adheres to the light yellow cloth and blue-violet light (center wavelength: 440 nm) is added to the reflected light, the whitening appears to be white. The color unevenness becomes significant when there is unevenness in the penetration of the high concentration detergent solution into the laundry. Therefore, before spraying the high-concentration detergent liquid, it is desirable that a small amount of water is wetted on the laundry in advance and then the high-concentration detergent liquid is sprayed while rotating the laundry at a low speed so that the laundry is uniformly permeated. .

本発明は、高濃度洗剤液の化学的洗浄力を有効に活用する洗濯機および洗濯乾燥機に関するものであるが、洗濯機は、洗濯乾燥機の乾燥機構を省略した形態で実施することができるので、以下、洗濯乾燥機の実施の形態を説明する。   The present invention relates to a washing machine and a washer / dryer that effectively utilize the chemical detergency of a high-concentration detergent solution, and the washing machine can be implemented in a form in which a drying mechanism of the washer / dryer is omitted. Therefore, an embodiment of the washing and drying machine will be described below.

この実施の形態における洗濯乾燥機は、洗濯物の量を検出して洗濯水の量（洗濯水位）を決定し、必要な粉末合成洗剤の量を決定する検出工程と、粉末合成洗剤を水で溶解して高濃度洗剤液を生成する高濃度洗剤液生成工程と、洗濯物に水を含ませて湿潤させるプレ給水工程と、粉末合成洗剤を溶解して生成した高濃度洗剤液を希釈しながら濡れた洗濯物に散布して浸透させる浸透工程と、高濃度洗剤液を浸透させた洗濯物を据え置く据え置き工程（必要に応じて省略する）と、洗い工程と、濯ぎ工程と、脱水工程と、温風乾燥工程を実行する。   The washing / drying machine according to the present embodiment detects the amount of laundry, determines the amount of washing water (washing water level), and determines a necessary amount of the powdery synthetic detergent. A high-concentration detergent solution producing step of dissolving to produce a high-concentration detergent solution, a pre-watering step of moistening the laundry by adding water thereto, and diluting the high-concentration detergent solution produced by dissolving the powdered synthetic detergent A penetrating step of spraying and infiltrating the wet laundry, a stationary step of leaving the laundry impregnated with the high-concentration detergent solution (omitted as necessary), a washing step, a rinsing step, and a dehydrating step; A hot air drying step is performed.

図１は、本発明の一実施の形態である洗濯乾燥機を縦断面して示す模式図である。   FIG. 1 is a schematic view showing a vertical section of a washing and drying machine according to an embodiment of the present invention.

１は、外郭を構成する枠体である。２は、洗濯兼脱水槽であり、その周壁に通水穴２ａを有し、その上縁部に流体バランサー３を備え、底部の内側には回転自在に撹拌翼４を設置する。撹拌翼４は、通水穴４ａを有する。５は、前記洗濯兼脱水槽２を内包する外槽であり、底部の外側には鋼板製の取付けベース７によって駆動装置６を設置する。洗濯兼脱水槽２は、枠体１の上端部の四隅から防振支持装置８によって懸垂するように支持される。   Reference numeral 1 denotes a frame constituting an outer shell. Numeral 2 denotes a washing and dewatering tub, which has a water passage hole 2a on its peripheral wall, a fluid balancer 3 on its upper edge, and a rotatable stirring blade 4 inside the bottom. The stirring blade 4 has a water passage hole 4a. Reference numeral 5 denotes an outer tub containing the washing and dewatering tub 2, and a driving device 6 is installed on the outside of the bottom by a steel plate mounting base 7. The washing and dewatering tub 2 is supported by the vibration isolating support device 8 from four corners at the upper end of the frame 1 so as to be suspended.

駆動装置６は、駆動電動機と電動操作クラッチ機構と遊星歯車減速機構を内蔵し、洗濯兼脱水槽２を静止させた状態で撹拌翼４を回転（撹拌モード）させ、洗濯兼脱水槽２と撹拌翼４をそれぞれ反対方向に回転（洗濯モード）させ、洗濯兼脱水槽２と撹拌翼４を一体的に同一方向に回転（脱水・乾燥モード）させるような選択的な駆動機能を有する。   The driving device 6 incorporates a drive motor, an electric operation clutch mechanism, and a planetary gear reduction mechanism, rotates the stirring blade 4 (stirring mode) while the washing and dewatering tub 2 is stationary, and stirs the washing and dewatering tub 2. It has a selective driving function of rotating the blades 4 in opposite directions (washing mode) and rotating the washing / dewatering tub 2 and the stirring blade 4 integrally in the same direction (dehydration / drying mode).

衣類投入開口９ａを形成した上面カバー９は、枠体１の上部開口を覆うように該開口端縁に嵌め込み、フロントパネル１０およびバックパネル１１と共に取付けねじで枠体１に取り付ける。   The upper surface cover 9 having the clothing input opening 9a is fitted to the opening edge so as to cover the upper opening of the frame 1, and attached to the frame 1 together with the front panel 10 and the back panel 11 with mounting screws.

上面カバー９とフロントパネル１０の間に形成されるフロントパネルボックス１２には、電源スイッチ１３と入力スイッチ群および表示素子群を備えた操作パネル１４と、外槽５内の水位に応じた水位信号を発生する水位センサ１５と、コントロールユニット１６を内蔵する。これらは、制御装置を構成する。   A front panel box 12 formed between the top cover 9 and the front panel 10 includes a power switch 13, an operation panel 14 having an input switch group and a display element group, and a water level signal corresponding to the water level in the outer tank 5. And a control unit 16 for generating a water level sensor. These constitute a control device.

上面カバー９とバックパネル１１の間に形成されるバックパネルボックス１７には、洗濯水給水手段と高濃度洗剤液生成手段を横並びに設置するように内蔵する。   In a back panel box 17 formed between the top cover 9 and the back panel 11, a washing water supply means and a high-concentration detergent liquid generating means are incorporated so as to be arranged side by side.

洗濯水給水手段は、入水側を水栓接続口１８に接続し、出水側を注水口１９に接続した主給水電磁弁２０を備える。   The washing water supply means includes a main water supply solenoid valve 20 having an inlet side connected to the faucet connection port 18 and an outlet side connected to the water inlet 19.

高濃度洗剤液生成手段は、補助給水電磁弁２２から洗剤溶解容器２１に少量の洗剤溶解水を供給し、この洗剤溶解容器２１内に投入されている粉末合成洗剤を電動駆動式の撹拌翼によって撹拌しながら前記洗剤溶解水で溶解して高濃度洗剤液を生成する。洗剤溶解容器２１は、給水口１９に連なる溢水部（図示省略）を有し、生成した高濃度洗剤液を更なる給水（希釈給水）によって希釈して増量することにより前記溢水部から溢水させて注水口１９に供給する。   The high-concentration detergent liquid generating means supplies a small amount of detergent dissolving water from the auxiliary water supply solenoid valve 22 to the detergent dissolving container 21, and the powder synthetic detergent charged in the detergent dissolving container 21 is stirred by an electrically driven stirring blade. Dissolve in the detergent-dissolved water while stirring to produce a high-concentration detergent solution. The detergent dissolving container 21 has an overflow portion (not shown) connected to the water supply port 19, and the generated high-concentration detergent solution is diluted with further water supply (diluted water supply) to increase the amount thereof, thereby causing the overflow from the overflow portion. It is supplied to the water inlet 19.

高濃度洗剤液を生成するための洗剤溶解水は、洗剤溶解容器２１の溢水部から溢水しない程度の少量に設定し、希釈給水時には、洗濯物に浸透させるのに好ましい洗剤濃度に希釈するために、主給水電磁弁２０も開放して追加の希釈水を注水口１９に供給するように構成する。   The detergent-dissolved water for producing the high-concentration detergent solution is set to such a small amount as not to overflow from the overflow portion of the detergent-dissolved container 21, and at the time of dilution water supply, in order to dilute to a detergent concentration preferable for permeating the laundry. The main water supply solenoid valve 20 is also opened to supply additional dilution water to the water inlet 19.

洗剤溶解容器２１の大きさは、バックパネルボックス１７内に設置するためには４００〜５００ｍＬ程度であることが望ましい。粉末合成洗剤を溶解して高濃度洗剤液を生成中に、前記溢水部から溢水させないためには、洗剤溶解水の量を１５０〜３００ｍＬとする。洗剤溶解水の量に差があるのは、粉末合成洗剤の種類（銘柄）により、洗剤溶解中の空気の巻き込みによる発泡状態が異なるからである。発泡が多い洗剤は、溶解中に見かけの容積が増加し溢水しやすいため、洗剤溶解水の量を少なくする必要がある。実際には、洗剤の種類と発泡状態は多様であり、溢水を防止するためには、洗剤溶解水量を１５０〜２００ｍＬ程度に設定するのが好ましい。   The size of the detergent dissolving container 21 is desirably about 400 to 500 mL for installation in the back panel box 17. In order to prevent the overflow from the overflow portion during the generation of the high-concentration detergent solution by dissolving the powdered synthetic detergent, the amount of detergent-dissolved water is set to 150 to 300 mL. The reason for the difference in the amount of detergent dissolving water is that the foaming state due to the entrainment of air during the dissolving of the detergent varies depending on the type (brand) of the powder synthetic detergent. A detergent with much foaming has an apparent volume that increases during dissolution and easily overflows. Therefore, it is necessary to reduce the amount of detergent dissolving water. Actually, the type of detergent and the foaming state are various, and in order to prevent overflow, it is preferable to set the amount of detergent dissolved water to about 150 to 200 mL.

洗濯容量８ｋｇの洗濯乾燥機の洗い水の量は、２４〜６８Ｌ程度であり、粉末合成洗剤を洗剤溶解水で溶解して生成する高濃度洗剤液の洗剤濃度は、洗い水の洗剤濃度の８０〜５００倍となる。この高濃度洗剤液は、洗濯物に散布して浸透させるときには、５〜２０倍（好ましくは約１０倍）に希釈する。   The amount of washing water in a washing / drying machine having a washing capacity of 8 kg is about 24-68 L, and the detergent concentration of a high-concentration detergent solution produced by dissolving a powdered synthetic detergent in detergent-dissolved water is 80% of the detergent concentration of the wash water. Up to 500 times. This high concentration detergent solution is diluted 5 to 20 times (preferably about 10 times) when sprayed and impregnated on laundry.

駆動装置６は、駆動電動機６１と電動操作クラッチ機構６２と遊星歯車減速機構６３と中心出力軸６４と外側出力軸６５を備え、鋼板製の取付けベース７の下面上に一体的に組み立て、この取付けベース７を外槽５の底下面にねじ止めすることにより取り付ける。   The drive device 6 includes a drive motor 61, an electric operation clutch mechanism 62, a planetary gear reduction mechanism 63, a center output shaft 64 and an outer output shaft 65, and is integrally assembled on a lower surface of the steel plate mounting base 7. The base 7 is attached to the bottom surface of the outer tank 5 by screwing.

駆動電動機６１は、複数段または無段変速の可逆回転型の電動機を使用する。この実施の形態においては、布量検出時に撹拌翼４を回転させる回転速度と、プレ給水時に洗濯兼脱水槽２と撹拌翼４を回転させる回転速度と、高濃度洗剤液を洗濯物に散布して浸透させるときに洗濯兼脱水槽２および／または撹拌翼４を回転させる回転速度と、洗濯時に遊星歯車減速機構の太陽歯車を回転させる回転速度と、脱水時に洗濯兼脱水槽２と撹拌翼４を一体的に回転させる回転速度と、温風乾燥時に洗濯兼脱水槽２と撹拌翼４を一体的に回転させ、撹拌翼４を単独で回転させる回転速度を好ましい値に制御することができるように構成する。   As the drive motor 61, a reversible rotation type motor of a plurality of stages or a continuously variable transmission is used.

そして、電動操作クラッチ機構６２は、電動操作機６２ａによって操作レバー６２ｂを操作することによって、撹拌モードと洗濯モードと脱水・乾燥モードに選択的に設定する。撹拌モードでは、遊星歯車減速機構６３の内歯車を静止部材に係合させることによって洗濯兼脱水槽２に静止力を作用させた状態で駆動電動機６１の回転力を遊星歯車減速機構６３と中心出力軸６４を介して撹拌翼４に伝達して該撹拌翼４を回転させて該撹拌翼４に作用する負荷量に基づく布量検出および布質検出を実行させる。洗濯モードでは、遊星歯車減速機構６３の内歯車を回転自由にした状態で駆動電動機６１によって太陽歯車を回転させることによって該駆動電動機６１の回転力を中心出力軸６４および外側出力軸６５の双方に反対向きに伝達して洗濯兼脱水槽２と撹拌翼４に反対向きに繰り返し正逆回転させて洗濯を実行させる。そして、脱水・乾燥モードでは、遊星歯車減速機構６２の内歯車を駆動電動機６１と連結状態として該駆動電動機６１によって太陽歯車と内歯車を一体的に回転駆動し、中心出力軸６４および外側出力軸６５を同一方向に回転させて洗濯兼脱水槽２と撹拌翼４に同一方向に低速回転させてプレ給水を実行させ、高速回転させて遠心脱水を実行させ、低速回転させて温風乾燥を実行させる構成である。   The electric operation clutch mechanism 62 selectively sets the stirring mode, the washing mode, and the dehydration / drying mode by operating the operation lever 62b with the electric operation device 62a. In the agitation mode, the internal gear of the planetary gear reduction mechanism 63 is engaged with the stationary member to apply a static force to the washing and spin-drying tub 2 so that the rotational force of the drive motor 61 is output to the central output of the planetary gear reduction mechanism 63 and the central output. The rotation is transmitted to the stirring blade 4 via the shaft 64, and the stirring blade 4 is rotated to execute the cloth amount detection and the cloth quality detection based on the load amount acting on the stirring blade 4. In the washing mode, the rotational force of the drive motor 61 is applied to both the center output shaft 64 and the outer output shaft 65 by rotating the sun gear by the drive motor 61 with the internal gear of the planetary gear reduction mechanism 63 being freely rotatable. The transmission is performed in the opposite direction, and the washing and dewatering tub 2 and the stirring blade 4 are repeatedly rotated in the normal and reverse directions in the opposite direction to execute the washing.

It is a structure to make it.

電源スイッチ１３を介して受電するコントロールユニット１６は、マイクロコンピュータ１６ａを中心にして構成し、電源回路１６ｂと、駆動装置６と主給水電磁弁２０と補助給水電磁弁２２と洗剤撹拌電動機３９と排水電磁弁３３と循環ファン２６とヒータ２９と冷却散水電磁弁２４ａへの給電を制御するための半導体交流スイッチング素子（ＦＬＳ）群を有する駆動回路１６ｃとを備える。   The control unit 16 that receives power via the power switch 13 is configured around a microcomputer 16a, and includes a power supply circuit 16b, a driving device 6, a main water supply solenoid valve 20, an auxiliary water supply solenoid valve 22, a detergent stirring motor 39, A drive circuit 16c having a group of semiconductor AC switching elements (FLS) for controlling power supply to the electromagnetic valve 33, the circulation fan 26, the heater 29, and the cooling watering electromagnetic valve 24a is provided.

In this embodiment, the rotation speed of the drive motor 61 is controlled by controlling the phase of the stator winding 61a by the FLSs 16c1 and 16c2, but a brushless motor driven by an inverter is used. The configuration can be configured to be performed by PWM control or PAM control.

Prepare. The drive circuit 16c controls the conduction state of the FLS 16c1 to FLS 16c10 in accordance with an instruction from the microcomputer 16a to perform power supply control to a dependent load.

マイクロコンピュータ１６ａは、更に、前記駆動電動機６１の回転センサ６１ｂ、電動操作クラッチ機構６２の位置センサ６２ｃ、外槽５内の洗濯水位を検出する水位センサ１５、洗剤溶解容器２１内に洗剤が投入されたことを検知する洗剤センサ４０、操作パネル１４に接続され、予め組み込まれた制御処理プログラムを実行することにより、操作パネル１４の入力スイッチ群１４ａと水位センサ１５と回転センサ６１ｂおよび位置センサ６２ｃからの信号を取り込み、駆動回路１６ｃを制御することによって、布量検出、高濃度洗剤液生成、プレ給水、高濃度洗剤液浸透、据え置き、洗い、濯ぎ、脱水および温風乾燥の各工程を実行し、操作パネル１４の表示素子群１４ｂを制御することによってその進行状況を表示する。   The microcomputer 16a is further provided with a rotation sensor 61b of the drive motor 61, a position sensor 62c of the electric operation clutch mechanism 62, a water level sensor 15 for detecting a washing water level in the outer tub 5, and a detergent supplied into the detergent dissolving container 21. Is connected to the operation panel 14 and executes a pre-installed control processing program, so that the input switch group 14a, the water level sensor 15, the rotation sensor 61b, and the position sensor 62c of the operation panel 14 By controlling the drive circuit 16c, the processes of cloth amount detection, high-concentration detergent solution generation, pre-water supply, high-concentration detergent solution infiltration, stationary, washing, rinsing, dehydration and hot-air drying are executed. By controlling the display element group 14b of the operation panel 14, the progress is displayed.

A switch for setting washing conditions such as water, dehydration time, water volume, and number of rinses, and a switch for setting a drying course (standard, shirt, blanket, etc.) when washing to drying are performed continuously.

次に、前記各工程について、高濃度洗剤液を洗濯物に浸透させることにより洗剤の化学的な洗浄力を効果的に発生させて洗濯、脱水および乾燥する場合を例示して説明する。   Next, each of the above steps will be described by exemplifying a case in which a high-concentration detergent solution is permeated into laundry to effectively generate a chemical detergency of the detergent for washing, dehydration and drying.

次に、このように構成された洗濯乾燥機の各工程の動作を説明する。図４は、コントロールユニット１６内のマイクロコンピュータ１６ａが実行する前記各工程のフローチャートである。   Next, the operation of each step of the washing and drying machine configured as described above will be described. FIG. 4 is a flowchart of each of the steps executed by the microcomputer 16a in the control unit 16.

マイクロコンピュータ１６ａは、入力スイッチ群１４ａの洗濯開始ボタンスイッチが投入されると次のような制御処理を実行する。   When the washing start button switch of the input switch group 14a is turned on, the microcomputer 16a executes the following control processing.

ステップ４０１
使用者が、洗濯兼脱水槽２に洗濯衣類３８を投入し、操作パネル１４の入力スイッチ群１４ａを操作して初期設定を行い、洗濯開始ボタンスイッチを押すと、マイクロコンピュータ１６ａは、各工程の自動運転制御処理をスタートする。 Step 401
When the user puts the laundry 38 into the washing and dewatering tub 2, operates the input switch group 14a of the operation panel 14 to perform the initial setting, and presses the washing start button switch, the microcomputer 16a performs Start the automatic operation control process.

前記初期設定では、洗濯物に合わせた洗濯コース、必要に応じて、洗い時間や脱水時間、水量、すすぎ回数等を設定する。さらに、洗濯の後、乾燥まで行う場合は洗濯乾燥コースを設定する。   In the initial setting, a washing course suitable for the laundry, a washing time, a dehydration time, a water amount, a number of rinses, and the like are set as necessary. Further, when washing and drying are performed, a washing and drying course is set.

ステップ４０２
洗濯物３８の布量の検出制御処理を行う。この布量検出は、給水前の乾布状態において、駆動装置６の電動操作クラッチ機構６２を撹拌モードに制御し、駆動電動機６１を短時間通電して撹拌翼４を回転駆動し、回転増速時の加速特性もしくは、駆動電動機６１への通電停止時の惰性回転における減速特性に基づいて検出する。この検出結果（洗濯物の布量）に基づいて、洗い水量および好ましい洗剤濃度の洗い水を生成するための洗剤量を演算して決定し、この洗剤量を表示素子群１４ｂによって表示する。使用者は、表示された洗剤量を参考に、洗剤溶解容器２１に粉末合成洗剤を投入する。 Step 402
A detection control process of the laundry amount of the laundry 38 is performed. This cloth amount detection is performed by controlling the electric operation clutch mechanism 62 of the driving device 6 to the stirring mode in a dry cloth state before water supply, energizing the driving motor 61 for a short time to rotationally drive the stirring blades 4, and increasing the rotation speed. , Or the deceleration characteristics in the inertial rotation when the power supply to the drive motor 61 is stopped. Based on this detection result (the amount of laundry), the amount of washing water and the amount of detergent for generating washing water having a preferable detergent concentration are calculated and determined, and this amount of detergent is displayed by the display element group 14b. The user puts the powdered synthetic detergent into the detergent dissolving container 21 with reference to the displayed detergent amount.

ステップ４０３
高濃度洗剤液の生成を行う。洗剤センサ４０により洗剤溶解容器２１に粉末合成洗剤が投入されたことを検知すると、補助給水電磁弁２２を開いて洗剤溶解容器２１に溢水しない程度の少量の水道水（洗剤溶解水）を供給する。そして、洗剤撹拌電動機３９に通電し撹拌翼を回転駆動し、洗剤溶解容器２１内の粉末合成洗剤を撹拌しながら溶解することによって高濃度洗剤液を生成する。 Step 403
Produces highly concentrated detergent liquid. When the detergent sensor 40 detects that the powdered synthetic detergent has been introduced into the detergent dissolving container 21, the auxiliary water supply electromagnetic valve 22 is opened to supply a small amount of tap water (detergent dissolving water) that does not overflow the detergent dissolving container 21. . Then, the detergent stirring motor 39 is energized to rotate the stirring blades, and the powder synthetic detergent in the detergent dissolving container 21 is dissolved while stirring, thereby producing a high-concentration detergent solution.

洗剤溶解水の量は、洗剤溶解容器２１の容量（大きさ）や洗いに使用する量の粉末合成洗剤を撹拌翼によって撹拌しながら均一に効率良く溶解し、しかも、撹拌中の洗剤の発泡による溢水が発生しない水量とする。例えば、洗剤溶解容器２１の容量が５００ｍＬ（溢水部までの容量４００ｍＬ）の場合、洗剤溶解水の量を１５０〜２００ｍＬに設定する。洗剤溶解水は、補助給水電磁弁２２の開弁時間によって制御する。生成される高濃度洗剤液の濃度は、洗剤溶解容器２１に投入された洗剤量（洗濯物の量、洗い水量）により異なる。例えば、洗濯容量８ｋｇの洗濯乾燥機の洗い水の量は、２４〜６８Ｌ程度であり、高濃度洗剤液は、洗い水の洗剤濃度の８０〜５００倍となる。   The amount of the detergent dissolving water is determined by uniformly dissolving the capacity (size) of the detergent dissolving container 21 and the amount of the powdery synthetic detergent used for washing uniformly and efficiently by stirring with stirring blades, and by foaming the detergent during stirring. The amount of water does not cause overflow. For example, when the capacity of the detergent dissolving container 21 is 500 mL (capacity up to the overflow section 400 mL), the amount of the detergent dissolving water is set to 150 to 200 mL. The detergent dissolving water is controlled by the opening time of the auxiliary water supply solenoid valve 22. The concentration of the high-concentration detergent solution generated depends on the amount of detergent (the amount of laundry and the amount of washing water) charged into the detergent dissolving container 21. For example, the amount of washing water in a washing / drying machine having a washing capacity of 8 kg is about 24-68 L, and the concentration of the high-concentration detergent solution is 80-500 times the detergent concentration of the washing water.

溶解時間は、２〜３分必要である。溶解時間は、粉末合成洗剤の種類により異なるが、溶けにくい洗剤でも２〜３分で溶解率が９５〜１００％となり、大部分の洗剤を溶かすことができるからである。   The dissolution time requires 2-3 minutes. Although the dissolution time varies depending on the type of the powdery synthetic detergent, even a hardly soluble detergent has a dissolution rate of 95 to 100% in 2 to 3 minutes, and most of the detergent can be dissolved.

ステップ４０４
駆動装置６の電動操作クラッチ機構６２を脱水・乾燥モードに制御し、駆動電動機６１を低速運転して洗濯兼脱水槽２と撹拌翼４を低速回転させながら主給水電磁弁２０を開いて水道水を注水口１９に直に供給して該水道水を洗濯兼脱水槽２内の洗濯物３８上に散布するプレ給水を行う。プレ給水量は、少なくとも洗濯物の最上面から布数枚程度の部分までが濡れる量とする。 Step 404
The electric operation clutch mechanism 62 of the driving device 6 is controlled to the dewatering / drying mode, and the driving water motor 61 is operated at a low speed to rotate the washing / dewatering tub 2 and the stirring blade 4 at a low speed, and the main water supply solenoid valve 20 is opened to supply tap water. Is supplied directly to the water inlet 19 to perform pre-water supply in which the tap water is sprayed on the laundry 38 in the washing / dewatering tub 2. The pre-water supply amount is an amount that wets at least a portion of the laundry from a top surface to about several cloths.

生成りや淡色の天然素材でできた衣料の色むらの原因となる粉末合成洗剤に含まれる蛍光増白剤は、染料の一種であり、洗濯物に触れるとすぐに吸着する。このため、高濃度洗剤液が直接かかる洗濯物最上部が最も蛍光増白剤が吸着しやすい。従って、乾いた洗濯物に高濃度洗剤液を散布すると、高濃度洗剤液の浸透過程で高濃度洗剤液が多く流れた部分とそうでない部分で蛍光増白剤の吸着量に差が生じすため、色むらが発生する。一方、洗濯物最上部からある程度離れると、浸透してきた高濃度洗剤液中の蛍光増白剤はほとんどなくなっており、蛍光増白剤の影響を受けにくくなる。プレ給水を行い、洗濯物を濡らすことで、高濃度洗剤液がより浸透しやすくなるため、高濃度洗剤液が洗濯物内に均一に拡散するため、蛍光増白剤が洗濯物に均一に吸着し色むらが防げる。ただし、変色（色むら）に対する官能試験によれば、プレ給水により蛍光増白剤の影響が許せる範囲は、高濃度洗剤液の濃度が２０倍以下（好ましくは１０倍以下にすると、ほとんど気にならないレベルになる）であり、これ以上の濃度では、プレ給水を行っても変色がやや気になるレベルになってしまう。このことから、変色（色むら）に関しては、高濃度洗剤液の濃度は２０倍以下に抑える必要がある。   A fluorescent whitening agent contained in a powdered synthetic detergent that causes color irregularities in clothing made of light-colored natural materials is a type of dye, and is absorbed immediately upon touching laundry. For this reason, the fluorescent brightener is most easily adsorbed to the uppermost portion of the laundry to which the high-concentration detergent liquid is directly applied. Therefore, when a high concentration detergent solution is sprayed on dry laundry, a difference occurs in the absorption amount of the optical brightener between a portion where the high concentration detergent solution flows a lot and a portion where the high concentration detergent solution does not flow during the permeation process of the high concentration detergent solution. , And color unevenness occurs. On the other hand, at a certain distance from the uppermost part of the laundry, the fluorescent brightener in the high-concentration detergent liquid that has permeated is almost eliminated, and the fluorescent brightener is less affected by the fluorescent brightener. By pre-watering and wetting the laundry, the high-concentration detergent liquid spreads more evenly in the laundry because the high-concentration detergent liquid spreads more easily in the laundry, so the fluorescent brightener is evenly adsorbed on the laundry Prevents color unevenness. However, according to the sensory test for discoloration (uneven color), the range in which the effect of the fluorescent whitening agent can be tolerated by the pre-water supply is almost unlimited when the concentration of the high-concentration detergent solution is 20 times or less (preferably 10 times or less). At a concentration higher than this, discoloration becomes slightly anxious even with pre-watering. For this reason, regarding the discoloration (uneven color), it is necessary to suppress the concentration of the high-concentration detergent solution to 20 times or less.

また、プレ給水量は、好ましくは、布量検出工程によって検出した洗濯物３８の量に応じて制御し、洗濯物３８の量が少ないときには少なくし、多くなるにつれて多くなるように制御する。これは、洗濯物が濡れていると、高濃度洗剤液がより浸透しやすくなるため、洗濯物全体に均一に高濃度洗剤液を浸透することができる。プレ給水量は、主給水電磁弁２０の開弁時間によって制御する。例えば、プレ給水量は、洗濯物３８の量が４ｋｇ未満の場合は４Ｌ程度、４〜８ｋｇの場合は１０Ｌ程度とする。   Further, the pre-water supply amount is preferably controlled in accordance with the amount of the laundry 38 detected in the cloth amount detection step, and is controlled so as to decrease when the amount of the laundry 38 is small and to increase as the amount increases. This is because when the laundry is wet, the high-concentration detergent liquid is more likely to penetrate, so that the high-concentration detergent liquid can uniformly penetrate the entire laundry. The pre-water supply amount is controlled by the opening time of the main water supply solenoid valve 20. For example, the pre-water supply amount is about 4 L when the amount of the laundry 38 is less than 4 kg, and is about 10 L when the amount of the laundry 38 is 4 to 8 kg.

なお、本プレ給水工程は、ステップ４０３の高濃度洗剤液生成工程と同時に行う。これは、上述のように、洗剤溶解に２〜３分必要で、この間にプレ給水工程を行うことで、洗濯時間を短縮できるからである。さらに、プレ給水終了後から洗剤溶解終了までの時間が据え置き時間となるため、水道水を洗濯物３８内に十分に浸透させることができる。例えば、主給水電磁弁２０からの給水流量が毎分１５Ｌでプレ給水量が１０Ｌとすると、プレ給水は４０秒で終了する。洗剤溶解時間が２分とすると、１分２０秒の据え置き時間がとれる。   The pre-water supply step is performed simultaneously with the high-concentration detergent liquid generation step in step 403. This is because, as described above, it takes 2 to 3 minutes for dissolving the detergent, and by performing the pre-watering step during this time, the washing time can be reduced. Further, the time from the end of the pre-water supply to the end of the detergent dissolution is the stationary time, so that the tap water can be sufficiently permeated into the laundry 38. For example, if the water supply flow rate from the main water supply solenoid valve 20 is 15 L / min and the pre-water supply amount is 10 L, the pre-water supply ends in 40 seconds. Assuming that the detergent dissolution time is 2 minutes, a stationary time of 1 minute and 20 seconds can be obtained.

ステップ４０５
駆動装置６の電動操作クラッチ機構６２を脱水・乾燥モードに制御し、駆動電動機６１を低速運転して洗濯兼脱水槽２と撹拌翼４を低速度で回転させながら補助給水電磁弁２２を開いて洗剤溶解容器２１に希釈給水することによって高濃度洗剤液を希釈して溢水部から溢水させることにより注水口１９に送り込む。同時に、主給水電磁弁２０を開いて注水口１９に給水して高濃度洗剤液を好ましい高濃度洗剤液に希釈して洗濯兼脱水槽２内の洗濯物３８に散布して該洗濯物３８に浸透させる。このときの高濃度洗剤液の好ましい洗剤濃度については、後述する。洗濯兼脱水槽２内の洗濯物３８は該洗濯兼脱水槽２と共に回転しているので、注水口１９から降りかけられる高濃度洗剤液は、洗濯物３８に均一に降りかけられて浸透する。洗濯物３８の回転は、洗濯兼脱水槽２を静止させた状態で撹拌翼４を回転させることによって撹拌するようにして行っても良い。特に攪拌翼４を洗濯兼脱水槽２に対して相対的に回転させることにより、洗濯兼脱水槽２の中で洗濯物が移動し位置が入れ替わるので、高濃度洗剤液を洗濯物３８により均一にかけることが可能になる。 Step 405
The auxiliary water supply solenoid valve 22 is opened while controlling the electric operation clutch mechanism 62 of the driving device 6 to the dehydration / drying mode and operating the driving motor 61 at a low speed to rotate the washing and dewatering tub 2 and the stirring blade 4 at a low speed. The high-concentration detergent solution is diluted by supplying diluted water to the detergent dissolving container 21 and overflowed from the overflow portion to be sent to the water inlet 19. At the same time, the main water supply solenoid valve 20 is opened and water is supplied to the water inlet 19 to dilute the high-concentration detergent solution into a preferable high-concentration detergent solution and spray it onto the laundry 38 in the washing and dewatering tub 2 to apply the same to the laundry 38. Let penetrate. The preferred detergent concentration of the high-concentration detergent solution at this time will be described later. Since the laundry 38 in the washing and dewatering tub 2 is rotating together with the washing and dewatering tub 2, the high-concentration detergent liquid flowing down from the water inlet 19 uniformly falls on the laundry 38 and permeates. The rotation of the laundry 38 may be performed by rotating the agitating blades 4 while the washing and dewatering tub 2 is stationary, thereby stirring the laundry. In particular, by rotating the stirring blade 4 relatively to the washing and dewatering tub 2, the laundry moves in the washing and dewatering tub 2 and the position is switched, so that the high-concentration detergent liquid is more uniformly distributed to the laundry 38. It becomes possible to call.

洗濯物３８に降りかけられた高濃度洗剤液は、速やかに洗濯物３８の内部に浸透して浸透し、洗濯物３８に付着した汚れに洗剤成分を作用させる。   The high-concentration detergent liquid that has fallen onto the laundry 38 quickly penetrates and penetrates into the interior of the laundry 38, and causes the detergent component to act on dirt attached to the laundry 38.

ステップ４０６
高濃度洗剤液を降りかけて浸透させた洗濯物３８を、所定時間据え置く。この据え置きは、洗濯物３８に対する高濃度洗剤液の浸透と汚れ対する洗剤の化学的洗浄力の作用を一層促進させるための時間であって、必要に応じて省略する。 Step 406
The laundry 38 in which the high-concentration detergent solution has descended and penetrated is left for a predetermined time. This deferment is a time for further promoting the penetration of the high-concentration detergent solution into the laundry 38 and the effect of the detergent's chemical detergency on stains, and is omitted as necessary.

ここで、高濃度洗剤液による洗浄度の向上について説明する。   Here, the improvement of the cleaning degree by the high concentration detergent solution will be described.

粉末合成洗剤は、洗剤成分として、汚れを落とす界面活性剤と、活性剤を補助するアルカリ剤、ゼオライト、酵素、再付着防止剤などのビルダー、蛍光増白剤などの添加剤を含んでいる。これらの成分のうち、高濃度洗剤液とした場合に洗浄力効能に寄与するのは、主に界面活性剤、ゼオライト、アルカリ剤、酵素である。   The powdery synthetic detergent contains, as detergent components, a surfactant for removing stains, an alkali agent for assisting the activator, a builder such as zeolite, an enzyme and an anti-redeposition agent, and an additive such as an optical brightener. Among these components, surfactants, zeolites, alkaline agents, and enzymes mainly contribute to the detergency when a high-concentration detergent solution is used.

界面活性剤は、その親油基を汚れの表面に向けて集まり汚れに吸着し、浸透作用で汚れと洗濯物にしみ込み、乳化作用で油汚れを水に溶かし、分散作用で親油性固体粒子を水と混ざり合いやすくする働きがある。そして、洗濯機の機械作用を加えることで、汚れは洗濯物から引き離なされ、洗い水中に移動する。   Surfactants gather their lipophilic groups toward the surface of dirt, adsorb to dirt, soak into dirt and laundry by penetrating action, dissolve oil dirt in water by emulsifying action, and disperse lipophilic solid particles by dispersing action. Has the effect of making it easier to mix with water. Then, by adding the mechanical action of the washing machine, the dirt is separated from the laundry and moves into the washing water.

図５は、洗濯物に浸透させる洗剤液濃度と洗浄率の関係を示すビーカ試験の結果である。この試験は、硬度１００ｐｐｍの洗剤溶解水で粉末合成洗剤を溶解して生成した洗剤液に、人工汚染布を５分間浸漬した（機械力は加えない）場合の洗剤濃度と洗浄率の関係を観察したものである。洗い水の洗剤濃度（１倍）における洗浄率は約３％であるが、５倍の洗剤濃度では洗浄率が１２％と急激に上昇し、１０倍で１５％、２０倍で１７％の洗浄率となるが、１０倍から２０倍では洗浄率の上昇は飽和傾向となる。この結果から、高濃度洗剤液の濃度は、５倍以上で最高でも２０倍程度でよいことがわかる。このように、高濃度洗剤液では、界面活性剤の働きが増強されるため、汚れを落とす作用が大幅に向上する。市販されているプレケア洗剤は、洗濯前に襟や袖などの汚れ部分に直接塗布する高濃度の液体洗剤であるが、図５の効果を利用したものである。なお、プレケア洗剤の洗浄力は、洗剤濃度１０倍の洗剤液と同等である。通常の粉末合成洗剤で作った高濃度洗剤液を洗濯物に浸透させることで、プレケア洗剤の効果を面倒な前処理を行うことなく実現できる。   FIG. 5 shows the results of a beaker test showing the relationship between the concentration of the detergent liquid permeated into the laundry and the cleaning rate. This test observes the relationship between the detergent concentration and the cleaning rate when an artificially stained cloth is immersed in a detergent solution produced by dissolving a powder synthetic detergent in detergent-dissolved water having a hardness of 100 ppm for 5 minutes (without applying mechanical force). It was done. The cleaning rate at the detergent concentration (1 time) of the washing water is about 3%, but at the detergent concentration of 5 times, the cleaning rate sharply rises to 12%, and the cleaning rate is 15% at 10 times and 17% at 20 times. However, at 10 to 20 times, the increase in the cleaning rate tends to be saturated. From this result, it is understood that the concentration of the high-concentration detergent solution may be 5 times or more and at most about 20 times. As described above, in the high-concentration detergent solution, the action of the surfactant is enhanced, and the action of removing dirt is greatly improved. The pre-care detergent on the market is a high-concentration liquid detergent that is directly applied to a stained portion such as a collar or a sleeve before washing, and utilizes the effect of FIG. The detergency of the pre-care detergent is equivalent to a detergent solution having a detergent concentration of 10 times. By infiltrating the laundry with a high-concentration detergent solution made with an ordinary powdered synthetic detergent, the effect of the pre-care detergent can be realized without troublesome pretreatment.

また、界面活性剤の濃度が高くなると、洗濯物に対する洗剤液の浸透速度が向上する。図６は、人工汚染布に対する洗剤液の浸透速度と洗剤液濃度の関係を測定した結果である。浸透速度は、水道水に対する比で表してある。浸透速度比は、洗剤濃度にほぼ比例している。洗剤濃度が洗い水と同じ１倍の場合は、浸透速度比は１．１程度で水道水とほとんど変わらないが、洗剤濃度が５倍では約３倍、１０倍で約４倍、２０倍で約８倍となる。このように、高濃度洗剤液を洗濯物に散布すると、浸透速度が大きいため、洗剤液が洗濯物に高速で浸透して素早く汚れに到達し、高濃度の洗剤成分が汚れに強力に作用し洗浄力が向上する。さらに、洗剤液が洗濯物に高速で浸透していくため、散布した洗剤液が洗濯物へ浸透せずに洗濯槽底部（外槽）に流出することがないため、高濃度洗剤液を有効に洗濯物に浸透させることができる。   Also, when the concentration of the surfactant increases, the penetration rate of the detergent liquid into the laundry increases. FIG. 6 shows the result of measuring the relationship between the penetration rate of the detergent solution into the artificially contaminated cloth and the detergent solution concentration. The permeation rate is expressed as a ratio to tap water. The penetration rate ratio is approximately proportional to the detergent concentration. When the detergent concentration is the same as that of the washing water, the penetration rate ratio is about 1.1, which is almost the same as that of tap water, but when the detergent concentration is 5 times, it is about 3 times, at 10 times, about 4 times, and 20 times. It becomes about 8 times. As described above, when a high-concentration detergent solution is sprayed on laundry, the permeation speed is high, so that the detergent solution permeates the laundry at high speed and quickly reaches the stain, and the high-concentration detergent component strongly acts on the stain. Detergency improves. Furthermore, since the detergent liquid permeates into the laundry at a high speed, the sprayed detergent liquid does not permeate into the laundry and does not flow out to the bottom (outer tub) of the washing tub, so that a highly concentrated detergent liquid can be effectively used. Can penetrate laundry.

ゼオライトは、水道水に含まれている金属イオン（硬度成分）を除去（軟水化）して、界面活性剤と硬度成分が結合することにより発生する金属石鹸の生成を抑制する。すなわち、洗い水中の有効な界面活性剤の量の減少を抑制するように機能する。しかし、粉末合成洗剤の一般的な使用量である２０ｇ／３０Ｌ（洗剤量／洗い水量）程度では、ゼオライトの量が不足して有効な界面活性剤が大幅に減少してしまう。   The zeolite removes metal ions (hardness components) contained in tap water (softens), and suppresses the production of metal soap generated by binding of the surfactant and the hardness components. That is, it functions to suppress a decrease in the amount of the effective surfactant in the wash water. However, when the amount of powdered synthetic detergent used is about 20 g / 30 L (detergent amount / washing water amount), the amount of zeolite is insufficient and the effective surfactant is greatly reduced.

しかしながら、少量の水道水（洗剤溶解水）で粉末合成洗剤を溶解して生成した高濃度洗剤液（例えば、洗い水の洗剤濃度の１０倍の洗剤濃度）は、金属イオンの量が少ないことから、ゼオライトが十分に機能して有効な界面活性剤の減少を極めて少量（約２％程度）に抑制することができる。   However, a high-concentration detergent solution produced by dissolving a powdered synthetic detergent in a small amount of tap water (detergent-dissolved water) (for example, a detergent concentration 10 times the detergent concentration of the wash water) has a small amount of metal ions. In addition, the zeolite functions sufficiently and the reduction of the effective surfactant can be suppressed to a very small amount (about 2%).

図７は、ゼオライト入り粉末合成洗剤を使用した場合の、洗剤溶解水の硬度と有効界面活性剤量（汚れに働きかけることができる界面活性剤量）との関係である。有効界面活性剤量は、投入した界面活性剤量に対する比率で表してある。すなわち、１００％は投入した界面活性剤がすべて有効なことを示し、割合が小さいほど硬度成分と界面活性剤が結合し金属石鹸化して、界面活性剤量が減少することを示す。   FIG. 7 shows the relationship between the hardness of detergent-dissolved water and the amount of effective surfactant (the amount of surfactant that can act on soil) when a zeolite-containing powdered synthetic detergent is used. The amount of the effective surfactant is represented by a ratio to the amount of the added surfactant. That is, 100% indicates that all the added surfactants are effective, and the smaller the ratio, the more the hardness component and the surfactant are bonded and metal-saponified, and the lower the amount of the surfactant.

硬度が高いほど、有効界面活性剤量が減少する。硬度１００ｐｐｍにおける有効界面活性剤の割合は、洗剤濃度１倍では９０％と有効界面活性剤量が１０％も減少するのに対して、濃度５〜１０倍の高濃度洗剤液では９８％と有効界面活性剤量の減少は２％に止まる。   The higher the hardness, the lower the amount of effective surfactant. The ratio of the effective surfactant at a hardness of 100 ppm is 90% when the detergent concentration is 1 time, and the amount of the effective surfactant is reduced by 10%. On the other hand, the effective surfactant is 98% when the detergent concentration is 5 to 10 times. The reduction in the amount of surfactant is only 2%.

このように、高濃度洗剤液では、洗剤溶解水量に対してゼオライトの量が多いため、洗剤溶解水から金属イオンが除去（軟水化）され、有効界面活性剤量を確保することができる。従って、上述の界面活性剤の作用が十二分に発揮され、高い洗浄力を得ることができる。このようにゼオライトは硬度の高い水（硬水）を軟水化する軟水化剤として用いられる。   As described above, in the high-concentration detergent solution, since the amount of zeolite is larger than the amount of detergent-dissolved water, metal ions are removed (softened) from the detergent-dissolved water, and the effective surfactant amount can be secured. Therefore, the action of the above-mentioned surfactant is sufficiently exerted, and a high detergency can be obtained. As described above, zeolite is used as a water softener for softening water having high hardness (hard water).

アルカリ剤は、洗剤液のアルカリ度（ＰＨ）調整と皮脂汚れ中の遊離脂肪酸を石鹸化し、汚れを取り除きやすくする働きがある。図８は、洗剤液の洗剤濃度とアルカリ度（ＰＨ）の関係を示す特性図である。アルカリ度は、水道水（ＰＨ７．３）から洗い水の洗剤濃度（洗剤濃度１倍）になると急激に上昇し、ＰＨ約１０となる。その後洗剤濃度が高くなるにつれて緩やかに上昇し、１０倍の高洗剤濃度ではＰＨ約１１となる。   The alkaline agent has a function of adjusting the alkalinity (PH) of the detergent solution and of saponifying free fatty acids in sebum dirt to facilitate removal of dirt. FIG. 8 is a characteristic diagram showing the relationship between the detergent concentration of the detergent solution and the alkalinity (PH). The alkalinity sharply rises from tap water (pH 7.3) to the detergent concentration of the wash water (detergent concentration 1 times), and becomes about pH 10. Thereafter, as the detergent concentration increases, the concentration gradually rises, and when the detergent concentration is ten times as high, the pH becomes about 11.

図９は、洗剤濃度１倍の洗い水におけるアルカリ度（ＰＨ）と化学的洗浄率の関係を示すビーカ試験の特性図である。この試験は、硬度０ｐｐｍの洗剤溶解水で粉末合成洗剤を溶解して生成した洗剤濃度１倍の洗剤液（洗い水）にアルカリ剤を添加してアルカリ度を変化させたときの洗浄率の変化を観察したものである。アルカリ度１０（洗剤濃度１倍の洗い水に相当）における洗浄率は約６％であるが、アルカリ度１１（１０倍の洗剤濃度の洗剤液に相当）では約８％の洗浄率となり、アルカリ度の向上で洗浄力が増加することがわかる。   FIG. 9 is a characteristic diagram of a beaker test showing the relationship between the alkalinity (PH) and the chemical cleaning rate in washing water having a detergent concentration of 1 times. In this test, the washing rate was changed when the alkalinity was changed by adding an alkali agent to a detergent solution (washing water) having a detergent concentration of 1 times, which was produced by dissolving a powdered synthetic detergent in detergent water having a hardness of 0 ppm. Is observed. At an alkalinity of 10 (corresponding to washing water with a detergent concentration of 1), the washing rate is about 6%, but at an alkalinity of 11 (corresponding to a detergent solution with a detergent concentration of 10 times), the washing rate is about 8%. It can be seen that the detergency increases with an increase in the degree.

酵素は、汚れ中のたんぱく質や脂質を分解する作用があり、界面活性剤による汚れの除去を容易にする。図１０は、酵素の有無による洗剤液の洗剤濃度と洗浄力の関係を示すビーカ試験の特性図である。この試験は、酵素配合の有無のみが異なる粉末合成洗剤を硬度０ｐｐｍの洗剤溶解水で溶解して生成した洗剤液の濃度と洗浄率の関係を観察したものである。酵素を配合した粉末合成洗剤の方が、洗剤濃度が高くなるに従って洗浄率が大幅に増加しており、高濃度酵素によりたんぱく質汚れや脂質汚れの分解が促進されることがわかる。   Enzymes have an action of decomposing proteins and lipids in soil, and facilitate the removal of soil by a surfactant. FIG. 10 is a characteristic diagram of a beaker test showing the relationship between the detergent concentration of the detergent solution and the detergency according to the presence or absence of the enzyme. In this test, the relationship between the concentration of a detergent solution produced by dissolving a powdered synthetic detergent differing only in the presence or absence of an enzyme with detergent-dissolved water having a hardness of 0 ppm and the washing rate was observed. In the case of the powdered synthetic detergent containing the enzyme, the washing rate was significantly increased as the detergent concentration was increased, and it was found that the high-concentration enzyme promoted the decomposition of protein stains and lipid stains.

以上のように、高濃度洗剤液を洗濯物に散布浸透させることで、高濃度の界面活性剤、ゼオライト、アルカリ剤、酵素の働きにより大幅な洗浄力を向上させることができる。   As described above, by spraying and penetrating a high-concentration detergent solution into laundry, a high-concentration surfactant, zeolite, an alkali agent, and an enzyme can significantly improve the detergency.

ステップ４０７
主給水電磁弁２０および補助給水電磁弁２２を開いて水道水（洗い水）の給水を開始する。この洗い水の給水は、ステップ４０２において決定した水量まで行うが、給水の途中で洗濯物３８の布量（湿布値）、布質を検出するために中断する。この中断水位は、マイクロコンピュータ１６ａに予め設定された湿布布量および布質検出に適した水位である。なお、補助給水電磁弁２２は、洗剤溶解容器２１を洗浄するために開放する。洗濯兼脱水槽２と撹拌翼４は、ステップ４０５と同様低速度で回転させた方がよい。これは、水道水を給水すると洗濯物３８に浸透していた約１０倍濃度の洗剤液が徐々に希釈されていくが、洗濯兼脱水槽２を回転させ洗濯物３８を回転させながら給水することで、洗濯物中の洗剤液が均一に希釈され、汚れ落ちのばらつきを小さくできるからである。中断水位まで給水すると、洗剤液の濃度は約２倍となるため、これ以降、洗濯兼脱水槽２を回転させながら給水する必要はない。 Step 407
The main water supply solenoid valve 20 and the auxiliary water supply solenoid valve 22 are opened to start supplying tap water (wash water). The supply of the wash water is performed up to the amount of water determined in step 402, but the supply of the wash water is interrupted during the supply of water to detect the amount of cloth (the value of the compress) and the quality of the laundry 38. The suspended water level is a water level suitable for detecting the amount of compress and the quality of the cloth set in the microcomputer 16a in advance. The auxiliary water supply electromagnetic valve 22 is opened to clean the detergent dissolving container 21. It is better to rotate the washing / dewatering tub 2 and the stirring blade 4 at a low speed as in step 405. This is because when the tap water is supplied, the detergent liquid having a concentration of about 10 times that has permeated the laundry 38 is gradually diluted, but the laundry / dehydration tub 2 is rotated to supply water while rotating the laundry 38. This is because the detergent liquid in the laundry is evenly diluted, and the variation in stain removal can be reduced. When the water is supplied to the suspended water level, the concentration of the detergent liquid becomes about twice, so that it is not necessary to supply water while rotating the washing and dewatering tub 2 thereafter.

ステップ４０８
湿布布量と布質を検出して洗い水給水量の補正と洗濯工程（洗い工程と濯ぎ工程）の決定を行う。この布質検出は、所定の低水位で給水を中断して駆動装置６の電動操作クラッチ機構６２を撹拌モードに制御し、駆動電動機６１を短時間付勢して撹拌翼４を回転駆動し、消勢時の惰性回転における第１の減速特性（湿布布量）を検出し、次いで、給水を再開して所定の高水位まで洗い水を補給した後に給水を中断して駆動装置６の駆動電動機６１を短時間付勢して撹拌翼４を回転駆動し、消勢時の惰性回転における第２の減速特性を検出し、この第１の減衰特性と第２の減衰特性の差に基づいて洗濯物３８の布質を検出する。この布質検出制御は、初期設定により不要になったときには、省略する。そして、布質に応じて、洗いおよび濯ぎ工程における時間と水流（機械的撹拌の強さ）を決定する。 Step 408
The amount of the compress and the quality of the cloth are detected to correct the amount of water supplied for washing and to determine the washing process (washing process and rinsing process). In this cloth detection, the water supply is interrupted at a predetermined low water level, the electric operation clutch mechanism 62 of the driving device 6 is controlled to the stirring mode, the driving motor 61 is energized for a short time, and the stirring blade 4 is rotationally driven. The first deceleration characteristic (amount of compress cloth) in the inertia rotation at the time of deenergization is detected, and then the water supply is resumed, the washing water is replenished to a predetermined high water level, the water supply is interrupted, and the drive motor of the drive device 6 is stopped. 61 is energized for a short time to rotationally drive the stirring blade 4 to detect a second deceleration characteristic in inertia rotation at the time of deenergization, and to perform washing based on a difference between the first attenuation characteristic and the second attenuation characteristic. The cloth of the object 38 is detected. This cloth quality detection control is omitted when it becomes unnecessary by the initial setting. Then, the time and the water flow (the intensity of mechanical stirring) in the washing and rinsing steps are determined according to the fabric quality.

ステップ４０９
ステップ４０２で決定した水量（水位）まで水道水を給水する。この給水により、洗い水は、高濃度洗剤液を希釈して洗いに好ましい洗剤濃度（１倍）となる。これにより、洗濯物３８は、洗濯兼脱水槽２内で所定の洗剤濃度（１倍）の洗い水に浸した状態となる。 Step 409
Tap water is supplied up to the water amount (water level) determined in step 402. By this water supply, the washing water is diluted with a high-concentration detergent solution to a detergent concentration (1 time) preferable for washing. As a result, the laundry 38 is immersed in the washing water having a predetermined detergent concentration (1 time) in the washing / dewatering tub 2.

ステップ４０７〜４０９の給水において高濃度洗剤液は高硬度の水道水で希釈されることになるが、洗剤成分は高濃度状態で洗濯物に浸透して汚れに作用した後であるので、これらの給水によって洗剤成分の洗浄作用が阻害されることはない。   In the water supply in steps 407 to 409, the high-concentration detergent liquid is diluted with high-hardness tap water. However, since the detergent components have penetrated into the laundry in a high-concentration state and acted on stains, these detergent components have been diluted. The water supply does not impair the cleaning action of the detergent components.

ステップ４１０
ステップ４０８において設定した洗い水流と洗い時間の洗い工程を行うように駆動装置６を制御する。この洗い工程においては、駆動装置６は、電動操作クラッチ機構６２を洗濯モードに制御し、駆動電動機６１の正逆運転を繰り返すことによって洗濯兼脱水槽２と撹拌翼４を反対向きに繰り返し正逆回転させる。 Step 410
The driving device 6 is controlled so as to perform the washing process with the washing water flow and the washing time set in step 408. In this washing step, the driving device 6 controls the electric operation clutch mechanism 62 to the washing mode, and repeats the forward / reverse operation of the driving motor 61 to repeatedly repeat the washing / dewatering tub 2 and the stirring blade 4 in the opposite direction. Rotate.

ここで、洗い工程における洗い時間と洗浄度と布絡み率の関係について説明する。   Here, the relationship between the washing time, the degree of washing, and the cloth entanglement ratio in the washing step will be described.

図１１は、洗い時間と洗浄度の関係を示している。洗い工程においては、洗濯物３８に付着した汚れを落とすために、洗濯兼脱水槽２と撹拌翼４を反対向きに繰り返し正逆回転させて洗濯物３８に機械力を作用させる。また、洗濯物３８の汚れには、洗剤の化学的な洗浄力が作用している。   FIG. 11 shows the relationship between the washing time and the washing degree. In the washing step, in order to remove dirt attached to the laundry 38, the washing and dewatering tub 2 and the stirring blade 4 are repeatedly rotated in the normal and reverse directions to apply mechanical force to the laundry 38. In addition, the detergent of the detergent 38 acts on the stains of the laundry 38.

特性曲線１００１は、洗濯物３８に高濃度洗剤液を浸透させる工程を行わないで洗剤を洗い水で溶解して洗い工程を実行したときのものである。すなわち、従来の洗濯方法で洗い工程を実行した場合の洗い時間と洗浄度を表わしたものである。従来の洗濯方法は、洗いに必要な洗剤量である２０ｇ／３０Ｌの割合で洗剤を投入して洗濯物を洗うものである。   The characteristic curve 1001 is obtained when the detergent is dissolved in the washing water and the washing process is performed without performing the process of infiltrating the laundry 38 with the high-concentration detergent solution. That is, it shows the washing time and the washing degree when the washing step is performed by the conventional washing method. The conventional washing method is to wash laundry by adding a detergent at a ratio of 20 g / 30 L, which is a detergent amount required for washing.

洗いは、洗濯物の汚れに対する洗剤の化学力と洗濯機の機械力の相乗効果で該汚れを洗濯物から除去することから、図１１に示す洗い時間と洗浄度指数の関係に従って洗浄度が向上する。従来の洗い時間は、約８〜１０分程度が一般的であり、このときの洗浄度指数は５０位となっている。   Washing removes dirt from the laundry by a synergistic effect of the chemical power of the detergent against the dirt on the laundry and the mechanical power of the washing machine. Therefore, the degree of cleaning is improved in accordance with the relationship between the washing time and the cleaning index shown in FIG. I do. The conventional washing time is generally about 8 to 10 minutes, and the washing index at this time is about 50th.

特性曲線１００２は、高濃度洗剤液を洗濯物３８に浸透させた後に洗い（撹拌）工程を実行したときのものである。この実施の形態においては、高濃度洗剤液を洗濯物３８に浸透させた後に洗い工程を実行しているので、特性曲線１００２に従った洗浄度を得ることができ、従って、比較的に短い洗い時間での小さい機械力によって必要な洗浄度を得ることができる。   A characteristic curve 1002 is obtained when a washing (stirring) step is executed after the high-concentration detergent liquid is permeated into the laundry 38. In this embodiment, since the washing process is performed after the high-concentration detergent solution is permeated into the laundry 38, a washing degree according to the characteristic curve 1002 can be obtained, and therefore, a relatively short washing time can be obtained. The required cleanliness can be obtained with small mechanical forces over time.

このように、高濃度洗剤液を浸透させ後に洗い工程へ移行して約８分間程度の撹拌を行うことにより、９０の洗浄度を実現することができる。   In this way, by infiltrating the high-concentration detergent solution and then proceeding to the washing step and stirring for about 8 minutes, a washing degree of 90 can be realized.

このことから、高濃度洗剤液を洗濯物３８に降りかけて浸透させる洗浄方式を採用することにより、洗い時間を５分以内としても、洗濯物３８の汚れは従来よりも良く落ちる。このために、洗濯機の機械力を低減しても洗浄力が向上する高濃度洗剤液浸透洗浄方式を提供することができる。   For this reason, by adopting a washing method in which the high-concentration detergent solution is caused to fall onto the laundry 38 and permeate the laundry 38, even if the washing time is within 5 minutes, the stain on the laundry 38 is better removed than before. Therefore, it is possible to provide a high-concentration detergent liquid permeation cleaning system in which the cleaning power is improved even if the mechanical power of the washing machine is reduced.

ここで、機械力は、洗濯兼脱水槽２および撹拌翼４の正逆回転のＯＮ−ＯＦＦ時限を調整したり、回転数を調整したり、洗い（撹拌）時間を調整したりすることによって制御することができる。   Here, the mechanical force is controlled by adjusting the ON / OFF time of the forward / reverse rotation of the washing / dewatering tub 2 and the stirring blade 4, adjusting the number of rotations, and adjusting the washing (stirring) time. can do.

図１２は、洗い時間と布絡み率の関係を示している。特性曲線１１０１は、小さい機械力で洗い工程を実行したときのものであり、特性曲線１１０２は、大きな機械力で洗い工程を実行したときのものである。洗い工程における機械力は、洗濯兼脱水槽２と撹拌翼４の撹拌力（正逆回転角度や回転速度）の大きさに比例することから、大きな機械力を発生させるためには、洗濯兼脱水槽２と撹拌翼４の回転角度が大きくなって布絡み率が大きくなる。この実施の形態においては、小さい機械力で必要な洗浄力を得ることができることから、特性曲線１１０１の布絡み率で洗い工程を実行することができ、１０％以下の布絡み率を実現することができる。すなわち、高濃度洗剤液浸透洗浄方式を採用することにより、小さい機械力でも従来の洗浄方式よりも洗濯物３８の汚れが良く落ちるようになることから、洗濯機の機械力を小さくして洗濯物３８の傷みや絡みを低減することができる。   FIG. 12 shows the relationship between the washing time and the cloth entanglement ratio. A characteristic curve 1101 is obtained when the washing process is performed with a small mechanical force, and a characteristic curve 1102 is obtained when the washing process is performed with a large mechanical force. The mechanical force in the washing process is proportional to the magnitude of the stirring force (forward / reverse rotation angle and rotation speed) of the washing / dewatering tub 2 and the stirring blade 4, and therefore, in order to generate a large mechanical force, the washing and dewatering is performed. The rotation angle between the water tank 2 and the stirring blade 4 increases, and the cloth entanglement ratio increases. In this embodiment, since the required detergency can be obtained with a small mechanical force, the washing step can be performed at the cloth entanglement rate of the characteristic curve 1101, and a cloth entanglement rate of 10% or less can be realized. Can be. That is, by adopting the high-concentration detergent liquid permeation cleaning method, even with a small mechanical force, the dirt on the laundry 38 can be removed better than in the conventional cleaning method. 38 can be reduced.

ステップ４１１
排水電磁弁３３を開いて洗い水を機外に排水する。 Step 411
The drainage solenoid valve 33 is opened to drain the washing water out of the machine.

ステップ４１２
主給水電磁弁２０と補助給水電磁弁２２を開いて濯ぎ水（水道水）を設定水量まで給水する。このとき（複数回の濯ぎを行うときには最終濯ぎのための給水時）には、必要に応じて、補助給水電磁弁２２ａも開いて柔軟仕上剤を投入する。 Step 412
The main water supply electromagnetic valve 20 and the auxiliary water supply electromagnetic valve 22 are opened to supply rinsing water (tap water) to a set water amount. At this time (when water is supplied for final rinsing when performing a plurality of rinsings), the auxiliary water supply electromagnetic valve 22a is also opened as necessary to supply a softening agent.

ステップ４１３
駆動装置６を制御して濯ぎ工程を実行する。高濃度洗剤液浸透洗浄方式による洗い工程では、高濃度洗剤液中のゼオライトによる軟水化作用が働くため、洗濯物３８への界面活性剤の吸着を増加させる金属石鹸の発生量が抑制される。このため、すすぎにおける界面活性剤の離脱が促進され、すすぎ性能が向上（希釈度が約２０％低減、希釈度：洗い水中の界面活性剤量に対するすすぎ水中の界面活性剤量の比）し、少ない濯ぎ力（機械力）で所定の濯ぎを実行することができる。 Step 413
The rinsing process is executed by controlling the driving device 6. In the washing process using the high-concentration detergent liquid permeation cleaning method, since the water softening action of the zeolite in the high-concentration detergent solution works, the amount of metal soap that increases the adsorption of the surfactant to the laundry 38 is suppressed. For this reason, the removal of the surfactant in the rinsing is promoted, and the rinsing performance is improved (the dilution degree is reduced by about 20%, the dilution degree: the ratio of the surfactant amount in the rinsing water to the surfactant amount in the washing water). The predetermined rinsing can be performed with a small rinsing force (mechanical force).

ステップ４１４
排水電磁弁３３を開いて濯ぎ水を機外に排水する。 Step 414
The drainage solenoid valve 33 is opened to drain the rinse water out of the machine.

ステップ４１５
排水電磁弁３３を開いたままにして駆動装置６の電動操作クラッチ機構６２を脱水・乾燥モードに制御し、駆動電動機６１を高速運転することによって洗濯兼脱水槽２と撹拌翼４を一体的に高速度で回転させることにより洗濯物３８の水分を遠心脱水する。この遠心脱水が終了した状態では、洗濯物３８は、洗濯兼脱水槽２の側壁に押し付けられて付着した状態にある。 Step 415
With the drainage electromagnetic valve 33 kept open, the electric operation clutch mechanism 62 of the driving device 6 is controlled to the dehydration / drying mode, and the driving motor 61 is operated at a high speed, so that the washing and dewatering tub 2 and the stirring blade 4 are integrally formed. By rotating at high speed, the water content of the laundry 38 is centrifugally dehydrated. In a state where the centrifugal dehydration is completed, the laundry 38 is in a state of being pressed against and adhered to the side wall of the washing and dewatering tub 2.

ステップ４１６
駆動装置６の電動操作クラッチ機構６２を脱水・乾燥モードに制御し、駆動電動機６１を低速運転して洗濯兼脱水槽２と撹拌翼４を低速度で回転させながら送風機２６を運転して外槽５内の空気を吸い出し口５ａから吸い出し、水冷除湿ダクト２３内を上昇する過程において冷却散水部２４から該水冷除湿ダクト２３内に供給する冷却水によって冷却除湿し、下降風路ダクト２５を通して循環ファン２６に吸い込み、この循環ファン２６から上昇風路ダクト２７とヒータ２９を通して吹き出し口３０に送り込み、ヒータ２９によって加熱して洗濯兼脱水槽２内の内壁面付近に向けて該洗濯兼脱水槽２の回転方向に対して逆向きに吹き込む循環空気を生成し、洗濯兼脱水槽２内の洗濯物を乾燥する。 Step 416
The electric operation clutch mechanism 62 of the driving device 6 is controlled to the dewatering / drying mode, the driving motor 61 is operated at a low speed, and the blower 26 is operated while rotating the washing and dewatering tub 2 and the stirring blade 4 at a low speed. 5 is sucked out from the suction port 5a, and is cooled and dehumidified by cooling water supplied from the cooling water sprinkling section 24 into the water-cooled dehumidifying duct 23 in the process of ascending the water-cooled dehumidifying duct 23. , And is sent from the circulation fan 26 to an outlet 30 through an ascending air duct 27 and a heater 29, heated by the heater 29, and directed toward the vicinity of the inner wall surface of the washing and dewatering tub 2. The circulating air blown in the direction opposite to the rotation direction is generated, and the laundry in the washing / dewatering tub 2 is dried.

遠心脱水されて洗濯兼脱水槽２の側壁に付着した状態のままの洗濯物３８を温風乾燥すると該洗濯物３８に皺が発生するために、乾燥時間中は、定期的に撹拌翼４を正逆回転させて洗濯物３８を動かしながら乾燥させるようにする。   When the laundry 38, which has been centrifugally dehydrated and adhered to the side wall of the washing and dewatering tub 2, is dried with hot air, wrinkles are generated in the laundry 38. Therefore, during the drying time, the stirring blade 4 is periodically turned on. The laundry 38 is dried by moving the laundry 38 forward and backward.

布絡み率が１０％以下であれば、最終脱水終了後にそのまま前述したように温風乾燥しても乾燥むらや皺の発生を防止することができる。   When the cloth entanglement ratio is 10% or less, uneven drying and wrinkles can be prevented even if the air is dried with hot air as described above after the final dehydration.

この実施の形態において、洗濯物に水を含ませて湿潤させる湿潤工程におけるための湿潤給水流量や、粉末合成洗剤を溶解して高濃度洗剤液を生成するための洗剤溶解給水流量や、高濃度洗剤液を希釈するための希釈給水流量と水量は、これらの給水を実行する主給水電磁弁２０と補助給水電磁弁２２の通水流量（通水流路面積）と給水時間によって設定するが、実際の給水流量は水源（水道）の水圧によって変動する。従って、主給水電磁弁２０と補助給水電磁弁２２の通水流量は、予想し得る最低水圧における通水流量を基準にして設定し、水位センサ１５を監視して所定の水位まで給水するときの実際の給水時間を計測し、計測した給水時間に基づいた演算処理によって水源の水圧を求めて記憶しておき、前記湿潤給水、洗剤溶解給水、希釈給水時には、主給水電磁弁２０および補助給水電磁弁２２を断続的に開閉して間欠給水することによってその平均値が所定の流量となるような流量制御を行う。   In this embodiment, the flow rate of the wet feed water for the wetting step in which the laundry is wetted with water, the flow rate of the detergent dissolving feed water for dissolving the powdery synthetic detergent to generate the high concentration detergent solution, and the high concentration The dilution water supply flow rate and the water amount for diluting the detergent liquid are set according to the water supply flow rate (water passage area) and the water supply time of the main water supply solenoid valve 20 and the auxiliary water supply solenoid valve 22 for executing the water supply. The water supply flow varies depending on the water pressure of the water source (tap). Accordingly, the flow rate of water through the main water supply solenoid valve 20 and the auxiliary water supply solenoid valve 22 is set based on the flow rate at the lowest possible water pressure, and the water level sensor 15 is monitored to supply water to a predetermined water level. The actual water supply time is measured, and the water pressure of the water source is obtained and stored by an arithmetic process based on the measured water supply time, and the main water supply solenoid valve 20 and the auxiliary water supply solenoid are used during the wet water supply, the detergent dissolution water supply, and the dilution water supply. By intermittently supplying water by opening and closing the valve 22 intermittently, flow control is performed so that the average value becomes a predetermined flow rate.
