る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine provided with a step of pre-soaking by lowering a washing water level as a preceding step of a washing step.
従来の技術 従来より、日本においては洗濯槽の底部に撹拌翼を設

るいわゆる渦巻式洗濯機が実用化されている。2. Description of the Related Art Conventionally, in Japan, a so-called spiral washing machine has been put into practical use, in which a stirring blade is provided at the bottom of a washing tub, and this rotation causes a swirling stirring water flow to be washed.
この種の洗濯機は、第７図に示すように、撹拌翼１は

定水位もしくは、洗濯に先立って設定された水位で運転
される。通常、洗濯に先立って洗剤を洗濯槽２内に入れ
るが、当然の結果として、洗濯行程内における洗剤濃度
は一定である。In this type of washing machine, as shown in FIG. 7, the stirring blade 1 was attached to the bottom portion 3 of the washing tub 2, and the rotation speed of the stirring blade 1 was set to about 150 rpm. That is, the stirring blade 1 having a relatively large diameter is rotated reversely and washed by the friction due to the difference in the movement of the laundry between the laundry 4 placed in the washing tub 2 near the stirring blade 1 and the distant material. Was there. When the water supplied from a water supply device (not shown) at the time of washing reaches a so-called specified water level a by a pressure switch or the like, water supply is stopped and washing is started. The basic process of a fully automatic washing machine is water supply-laundry-drainage-dewatering-water supply-rinse-drainage-dewatering-water supply-rinse-drainage-dewatering, and the water level for washing and rinsing is always the specified water level or for washing. It is operated at the water level set in advance. Usually, the detergent is put into the washing tub 2 prior to washing, but as a result, the detergent concentration in the washing process is constant.
したがって、常に一定の洗剤濃度下において、撹拌翼
１を反転回転させて洗濯をするもので、一定の洗浄効果

くなり、さらには被洗浄物のからみを良くしようとする
と、洗いむらが発生していた。Therefore, in order to maintain a constant level of cleaning effect, the entanglement of the object to be cleaned becomes large, and further the object to be cleaned becomes large in order to wash by rotating the stirring blade 1 in reverse under a constant detergent concentration. Uneven washing occurred when trying to improve the entanglement of things.

うこともあり、洗浄むらが大きくなるという課題を有し
ていた。In the water flow of a conventional washing machine, the weight of an object to be washed is divided into multiple stages, and the reversal time limit of the reversal rotation is set so as to achieve a target cleaning effect with the set amount. Therefore, the cleaning effect is not a problem, but on the other hand, there is a problem that the cloth clogging, which is a characteristic of the stirring blade, becomes large. Fig. 8 shows the change in performance when washing is performed for the reversal time period of the rated specified amount and the reversal time period shorter than that. In the figure, the washing effect, washing unevenness, and cloth entanglement are 100
It can be seen that as the reversal time period becomes smaller, the cloth entanglement decreases, but the cleaning unevenness increases. The cause of the change in the washing characteristics due to the decrease of the reversal time is that the water flow formed by the reversal time of the reversal rotation of the stirring blade sets the strength of the water flow by the time control of the reversal time of the stirring blade. is there. This is because the stirring blade must increase the number of rotations or increase the rotation torque in order to transmit the stirring force to the object to be cleaned at the top of the washing tub. In order to achieve this, it is necessary to lengthen the reversal time of the stirring blades, which causes the entanglement of the clothes at the bottom of the washing tub to become severe. If the reversal time is short, the agitation power is weak, and the movement of the object to be washed on the top becomes small, and the part that is not submerged in the washing liquid may end without being used in the washing process and cannot be washed. Had the problem of becoming larger.
このような課題を解決するために、洗濯水面の情報か

る。また、この構成では、洗濯行程・すすぎ行程におけ
る撹拌中に洗濯槽の洗濯水面から洗濯水が飛び散り洗濯
機の接地面が水浸しになるなどの場合も生じていた。In order to solve such a problem, a washing machine having a structure in which the washing water is applied from the information on the surface of the washing water has also been proposed, but when the washing water that descends from above hits the floating object to be washed, bubbles are generated by the impact. It tends to occur, and the bubbles overflow from the washing tub and cannot be received by the water receiving tub. Further, in this configuration, there is a case where the washing water is scattered from the washing water surface of the washing tub and the ground contact surface of the washing machine is submerged during stirring in the washing process and the rinsing process.
本発明は、上記課題に鑑み、布からみを激しく生ずる
ことなく、洗浄効果、洗浄むらの低減を向上させるとと
もに、洗濯水面からの泡や洗濯水の洗濯槽からの放出を
防止することを目的としている。In view of the above problems, the present invention aims to improve the cleaning effect, the reduction of the cleaning unevenness, and prevent the foam from the surface of the washing water and the discharge of the washing water from the washing tub without causing the cloth to be severely entangled. There is.

平方向に細長いスリット状の噴射口を有し洗濯水を略水
平方向で洗濯水面上に噴射する広域噴射形成部を備えて
おり、広域噴射した洗濯水が洗濯槽水面に流出するよう
にしたものである。Means for Solving the Problems In order to achieve the above object, a washing machine of the present invention has a wide horizontal jet having a slit-like jet port in a substantially horizontal direction and jetting washing water in a substantially horizontal direction onto a washing water surface. It is provided with a forming part so that the washing water sprayed over a wide area flows out to the surface of the washing tub.
また、撹拌翼の裏面に形成した羽根によるポンプ作用

時限を定格規定量より短くして、回転・停止を繰り返す
構成としたものである。In addition, by utilizing the pumping action of the blades formed on the back surface of the stirring blade, the washing water is forced to rise, the reversal time limit of the stirring blade is made shorter than the rated amount, and rotation and stop are repeated. Is.
さらに、定格規定水位より低い水位で洗濯物（被洗浄
物）を撹拌する構成としたものである。Further, the laundry (washed object) is agitated at a water level lower than the rated water level.
作用 上記構成のような広域噴射形成部を有することによ

発生することはなく、洗濯槽からの泡の放出を防止する
ことができる。同様に洗濯水の飛び散りもこの膜状の洗
濯水により遮られる。By having the wide-area jet forming portion having the above-described configuration, a thin film-like washing water is formed from the elongated slit-shaped jet port so as to cover the upper portion of the washing water surface, and floats on the washing water surface to be used for the washing water. By applying to the uncleaned object, the cleaning effect and the reduction of cleaning unevenness can be improved. Furthermore, the foam generated from the surface of the washing water is blocked by the thin washing water film formed so as to cover the upper surface of the washing water, and the disappearance of the foam here prevents the foam from being generated beyond this film. In addition, it is possible to prevent the foam from being discharged from the washing tub. Similarly, splashes of washing water are also blocked by this film-like washing water.

き（撹拌翼が回転しているとき）にしか生ずることはな
いため問題はない。In addition, since the thin-film washing water is formed from the wide-area jet forming portion so as to cover the upper surface of the washing water by the pumping action of the stirring blade, the thin-film washing water is interlocked with the rotation / stop movement of the stirring blade. Moves from near the wall of the washing tub toward the center of the tub. Due to the movement of the film-like washing water, the frequency of splashing on the surface of the washing water and the non-washed article to be washed increases, and the washing effect and uneven washing can be improved. However, in this case, in the conventional drive of the stirring blade in the reversal time period, the supply of the washing water that forms the film covering the upper part of the washing tub cannot be supplied in time, the injection of the washing water is interrupted, and the foam discharge can be prevented. The problem of disappearing arises. In order to solve this problem, by shortening the reversal time of the stirring blade, the time for which the film is cut off is shortened, and the generation of bubbles is surely extinguished without being left to prevent the emission of bubbles. There is no problem with splashing of washing water because it occurs only when the film is formed (when the stirring blade is rotating).
さらに、規定水位より低い水位で被洗濯物を撹拌する
行程を設けることにより、洗剤量を増加させることなく
高濃度の洗濯水で洗浄することができ、更に広域噴水し
た洗濯水が上部よりふりかかることにより、落ちにくい
汚れに対して有効に洗剤が働き洗浄効果・洗浄むらの低
減を向上させることができる。Furthermore, by providing a process to stir the laundry at a water level lower than the specified water level, it is possible to wash with high-concentration washing water without increasing the amount of detergent, and the washing water sprinkled over a wider area sprinkles from the top. As a result, the detergent works effectively against stains that are difficult to remove, and the cleaning effect and the reduction in cleaning unevenness can be improved.

The rotation force of the motor 11 is applied to the reduction mechanism unit 10 for selectively rotating the washing tub 7 and the stirring blade 9 to rotate the motor pulley 12 and the V belt 1.
3, the motor 11 is transmitted via the pulley 14 and the control device 15 controls the motor 11. Reference numeral 16 is an electromagnetic water supply valve, and 17 is a pressure sensor for detecting a plurality of water levels in the washing tub 7. Further, a plurality of rising water flow path establishing parts 19 for establishing the forced rising water flow path 18 are attached to the washing tub 7, and the upper outlet of the rising water flow path establishing part 19 enables a wide area fountain. Is provided. Further, a rising water flow vane 21 for sending washing water to the forced rising water flow path 18 is integrally formed in the lower part of the stirring blade 9.

みが悪化するという問題が発生する。The operation of the above configuration will be described. Prior to washing, clothes 22 and detergent are put into the washing tub 7. The detergent amount is usually added at a fixed ratio to the washing water amount. For example, if the washing water amount is 50 and the laundry 22 is 4.5 kg in a dry state, the standard water amount for washing 50 is the water level shown in FIGS. The water level indicated by 23 in the figure is the rated specified water level for the rated clothing. Also, the standard amount of detergent is 0.133% of the amount of washing water, so 66.5 g of detergent is added. Then, if the controller 15 is operated, the electromagnetic water supply valve 16
Is activated and water supply starts. The supplied water level is the specified water level
When it becomes 23, the pressure sensor 17 operates to cut off the energization to the electromagnetic water supply valve 16, and at the same time, the motor 11 is energized to rotate the stirring blade 9 and start washing. When washing is performed without the wide-area fountain forming unit 20 as in the conventional case, as shown in FIGS. 3 and 4, the washing effect is that the lower half of the laundry 22 can be washed and the upper half of the clothing 22 can be washed. It can be seen that the result is that the cleaning cannot be performed and the cleaning unevenness is large. This is because the stirring force of the stirring blade 9 is difficult to be transmitted to the upper side, and the clothes 22 above the prescribed water level 23 cannot be washed. Further, in order to reduce the uneven cleaning, if the reversing time limit of the stirring blade 9 is set to be long and the clothes can be switched up and down, there is a problem that the entanglement of the clothes deteriorates as shown in FIG.
そこで、本発明では、広域噴水形成部20を有効に利用
することを目的とし、以下のように動作させる。Therefore, in the present invention, the purpose is to effectively use the wide area fountain formation unit 20, and the operation is performed as follows.
第５図および第６図のように、給水された水位が、規

とり出せるようにしたものである。As shown in FIG. 5 and FIG. 6, when the supplied water level becomes lower than the regulated water level 23, the pressure sensor 17 operates and the electromagnetic water supply valve 16 is deenergized, and at the same time, the motor 11 is energized and agitated. The wing rotates and starts pre-soaking washing. Therefore, at the start of this pre-soaking washing, the detergent concentration is higher than the standard concentration, and for example, if the water amount at the water level 24 is 25, the detergent concentration for the washing water amount is Then, wash with double the concentration. When some time has passed after the start of pre-soaking washing, for example, 5 minutes, the electromagnetic water supply valve 16
When the water is supplied to the rated specified water level 23, the pressure sensor 17 operates and the electromagnetic water supply valve 16 is de-energized.From here, the so-called rated water volume for the rated clothing capacity and the standard concentration of 0.133% for the detergent are applied. The washing process is started, the washing time is normally set to about 10 minutes, and the washing is continued during that period, and when the washing time elapses, the process goes to the water supply-dehydration-rinsing process. Here, the pressure sensor 17 is adapted to extract a plurality of detected water level values.
この予浸洗濯時において、撹拌翼９は右回転−休止−

り、まんべんなく掛かるようにしている。At the time of this pre-soaking washing, the stirring blade 9 rotates clockwise-pause-
Reversed to the left, the rotation speed is around 10 rotations per minute or less, and it is rotated at a relatively low speed, and the unidirectional operation time is set to a few seconds or less and the operation is performed in small increments. The washing water is constantly spouted from the fountain forming part 20 so that the clothes 22 on the upper part can be spread evenly over a wide area.
また、洗濯時には従来の反転時限より短かい小刻み運
転をし、ここでも洗濯水が常に広域噴水形成部20より噴

なく掛かるようにしている。In addition, during washing, a short wiggle operation is performed, which is shorter than the conventional reversal time period, and the washing water can be constantly spouted from the wide area fountain forming section 20 so that the clothes 22 on the upper portion can be evenly spread over a wide area.
このように本実施例は予浸洗濯行程を洗剤濃度の濃い
状態で洗濯をし、さらには、予浸洗濯行程でも洗濯行程
でも上部より洗濯水を洗濯槽７内の衣類22に掛けるもの
である。As described above, in this embodiment, the pre-soaking washing process is carried out in the state where the detergent concentration is high, and further, the washing water is applied to the clothes 22 in the washing tub 7 from the upper portion in both the pre-soaking washing process and the washing process. .
この洗剤濃度の濃い状態では洗濯は、標準濃度の時よ
り水量が少なく、一般に洗濯衣類22が動きにくいことは
否めない。しかし、布の動きが少なくても洗剤濃度が濃
いことにより、洗浄効果はよく、さらに本実施例では、
広域噴水形成部20から洗濯水が洗濯衣類22に掛かるた
め、洗濯水の水位より上にある洗濯衣類22に広範囲にわ
たり、まんべんなく洗濯水がしみるため、効果をさらに
向上させると共に洗浄むらが低減できる。It is undeniable that, in the state where the detergent concentration is high, the amount of water in washing is smaller than that in the standard concentration, and thus the laundry clothes 22 are generally hard to move. However, even if the movement of the cloth is small, the detergent concentration is high, so that the cleaning effect is good.
Since the washing water is applied to the laundry clothes 22 from the wide-area fountain formation unit 20, the laundry clothes 22 above the water level of the washing water can be spread over a wide area evenly, so that the effect can be further improved and uneven cleaning can be reduced. .

じて加減するのが賢明である。そこで、汚れのひどい時
には洗剤濃度を濃くするのがよいのであるが、標準水量
に対して濃度を濃くする方法は洗剤量を多く要し好まし
くない。Detergents are generally washed by adding an amount corresponding to the standard concentration. However, there are many kinds of stains in real life, and these stains are mixed and the degree of stains ranges from severe stains to light stains. Therefore, it is not generally preferable to wash only with the standard concentration, and it is advisable to adjust the degree according to the type and degree of stains. Therefore, it is preferable to increase the concentration of the detergent when the soil is extremely dirty, but the method of increasing the concentration with respect to the standard amount of water requires a large amount of detergent and is not preferable.
よって本発明は洗濯行程の前行程として予浸洗濯を

向上できるのである。Therefore, the present invention performs pre-soak washing as a preceding step of the washing step, which makes the detergent concentration thicker at a water level lower than the rated prescribed water level to exert a sufficient detergent cleaning effect on stains that are difficult to remove, With the standard water amount and standard concentration, it provides a sufficient agitation effect, and without requiring a large amount of detergent, the cleaning effect can be improved by about 10% compared to the conventional method. Since the water is evenly spread over the laundry 22 that is higher than the washing water over a wide area, it is not necessary to set a long reversal time period so that the laundry water 22 is lined in sequence with the washing water, and a short reversal time period reduces uneven washing. Since it is possible, the entanglement of the cloth can be improved.

By applying the cleaning material, the cleaning effect and the reduction of cleaning unevenness can be improved. Furthermore, the foam generated from the surface of the washing water is blocked by the thin washing water film formed so as to cover the upper surface of the washing water, and the disappearance of the foam here prevents the foam from being generated beyond this film. In addition, it is possible to prevent the foam from being discharged from the washing tub. Similarly, splashes of washing water are also blocked by this film-like washing water.

いため問題はない。In addition, since the thin film-like washing water is formed from the wide-area jet forming part so as to cover the upper part of the washing water surface by the pumping action of the stirring blade, the thin film-like selective water is interlocked with the movement of the stirring blade rotating and stopping. Moves from near the wall of the washing tub toward the center of the tub. Due to the movement of the film-like washing water, the frequency of splashing on the surface of the washing water and the non-washed article to be washed increases, and the washing effect and uneven washing can be improved. However, in this case, in the conventional drive of the stirring blade in the reversal time period, the supply of the washing water that forms the film covering the upper part of the washing tub cannot be supplied in time, the injection of the washing water is interrupted, and the foam discharge can be prevented. The problem of disappearing arises. In order to solve this problem, by shortening the reversal time of the stirring blade, the time for which the film is cut off is shortened, and the generation of bubbles is surely extinguished without being left to prevent the emission of bubbles. There is no problem with splashing of washing water because it occurs only when the film is formed (when the stirring blade is rotating).

減を向上させることができる。Furthermore, by providing a process to stir the laundry at a water level lower than the specified water level, it is possible to wash with high-concentration washing water without increasing the amount of detergent, and the washing water sprinkled over a wider area sprinkles from the top. As a result, the detergent works effectively against stains that are difficult to remove, and the cleaning effect and the reduction in cleaning unevenness can be improved.
