(本開示の基礎となった知見等)
発明者らが本開示に想到するに至った当時、洗濯権脱水槽の槽内をすすぐ際には、水が接触する部分しかすすげないため、洗濯していた水位やすすぎたいと考えている水位より、すすぐ水位を高く設定する技術があった。これにより多くの水を必要としていた。
(Findings, etc. that form the basis of this disclosure)
At the time when the inventors came up with this disclosure, when rinsing the inside of the washing right dehydration tank, the part that comes into contact with water is not faint, so we would like to rinse the water level that was being washed. There was a technique to set the rinse water level higher than the water level. This required more water.

また、少ない水で洗濯権脱水槽の槽内をすすぐ方法としては、特許文献1のように、排水弁を開いた後、洗濯兼脱水槽を規定の回転数まで略一定時間で加速するとともに、左右両方向に回転させ、給水を洗濯兼脱水槽の停止から回転上昇時、あるいは回転上昇時に行う技術があった。これは、給水時の水の飛び跳ねを利用し、回転数を高くするほど、水の飛び跳ねの位置が高くなることを利用したもので、水の飛び跳ねが洗濯兼脱水槽の槽内に限ることで、洗濯兼脱水槽の外面や水槽の内面はすすげないものであった。そして、水槽の内面、洗濯兼脱水槽の内面、外面を均一にすすぐことが困難であり、ムラができること、内蓋がないと機外への水飛びが発生しやすいこと等の課題を発明者らは発見し、その課題を解決するために、本開示の主題を構成するに至った。
□そこで本開示は、専用のコースとして、少ない水で、水飛びを防止しつつ、水槽の内面、洗濯兼脱水槽の内面、外面を効果的にすすぐことができ、清潔感を向上させ、使用者の要求を満足させることができる洗濯機を提供する。
Further, as a method of rinsing the inside of the washing right dehydration tub with a small amount of water, as in Patent Document 1, after opening the drain valve, the washing / dehydrating tub is accelerated to a specified rotation speed in a substantially constant time, and at the same time, There was a technique of rotating in both left and right directions to supply water when the washing and dehydration tub was stopped and the rotation increased, or when the rotation increased. This uses the splash of water during water supply, and the higher the number of revolutions, the higher the position of the splash of water. The outer surface of the washing / dehydrating tub and the inner surface of the water tub were not so good. Then, the inventor has problems such as it is difficult to uniformly rinse the inner surface of the water tank, the inner surface and the outer surface of the washing / dehydrating tank, unevenness is formed, and water splashes easily to the outside of the machine without the inner lid. Et al. Have discovered and constructed the subject matter of this disclosure in order to solve the problem.
□ Therefore, as a dedicated course, this disclosure can effectively rinse the inner surface of the aquarium, the inner surface of the washing / dehydrating tank, and the outer surface with less water while preventing water from splashing, improving the cleanliness and using it. Provide a washing machine that can satisfy the demands of the person.

[1−2.動作、作用]
以上のように構成した洗濯機において、以下、その動作、作用を説明する。
[1-2. Action, action]
The operation and operation of the washing machine configured as described above will be described below.

なお、ここで、図1における水位H1〜水位H5を以下の通り設定する。 Here, the water levels H1 to H5 in FIG. 1 are set as follows.

水位H1は、パルセータ8の上縁部が浸かる水位、水位H2は、パルセータ8の上縁部と中部吐出口12の間に位置する水位、水位H3は、中部吐出口12より若干上、すなわ
ち中部吐出口12が浸かる水位、水位H4は、上部吐出口11と中部吐出口12の間に位置する水位、水位H5は、上部吐出口11より若干下の水位としている。
The water level H1 is the water level at which the upper edge of the pulsator 8 is immersed, the water level H2 is the water level located between the upper edge of the pulsator 8 and the middle discharge port 12, and the water level H3 is slightly above the middle discharge port 12, that is, the middle part. The water level at which the discharge port 12 is immersed, the water level H4 is the water level located between the upper discharge port 11 and the middle discharge port 12, and the water level H5 is a water level slightly lower than the upper discharge port 11.

通常の洗濯コースにおいては、洗濯物の量によって、水位を設定するが、洗濯物の量が多い場合、水位H5で洗濯を行い、洗濯物の量が中位の場合、水位H4で洗濯を行い、洗濯物の量が少ない場合、水位H3にて洗濯を行う。 In a normal washing course, the water level is set according to the amount of laundry, but if the amount of laundry is large, washing is performed at water level H5, and if the amount of laundry is medium, washing is performed at water level H4. If the amount of laundry is small, wash at the water level H3.

図3に基づいて、洗濯機1の槽すすぎコースの動作を説明する。 The operation of the tub rinsing course of the washing machine 1 will be described with reference to FIG.

図3において、洗濯兼脱水槽7内が空の状態で、操作表示部23に表示されている槽すすぎコース(図示せず)を選択し、スタートボタン(図示せず)を押して、槽すすぎコースをスタートする(ステップS100)。 In FIG. 3, with the washing / dehydrating tub 7 empty, the tub rinsing course (not shown) displayed on the operation display unit 23 is selected, and the start button (not shown) is pressed to perform the tub rinsing course. Is started (step S100).

スタートすると、排水弁26が閉じた状態で給水弁22が動作して第1の所定水位(例えば、水位H3)まで給水する(ステップS101)。給水が始まると、給水途中の第2の所定水位(例えば、水位H2)でパルセータ8を回転させ、給水しながら攪拌動作を行う(ステップS102)。ここでは、給水しながら、中部吐出口12から洗濯兼脱水槽7内に向かって散水し、洗濯兼脱水槽7の内面の下部を洗浄してすすいでいる。 When started, the water supply valve 22 operates with the drain valve 26 closed to supply water to the first predetermined water level (for example, water level H3) (step S101). When the water supply starts, the pulsator 8 is rotated at the second predetermined water level (for example, the water level H2) during the water supply, and the stirring operation is performed while supplying the water (step S102). Here, while supplying water, water is sprinkled from the central discharge port 12 toward the inside of the washing / dehydrating tank 7, and the lower part of the inner surface of the washing / dehydrating tank 7 is washed and rinsed.

そして、第1の所定時間(例えば、30秒)が経過すると、パルセータ8の攪拌は停止するが、給水はそのまま継続し(ステップS103)、第1の所定水位になると給水弁22を閉じて、給水を停止する(ステップS104)。 Then, when the first predetermined time (for example, 30 seconds) elapses, the stirring of the pulsator 8 is stopped, but the water supply continues as it is (step S103), and when the first predetermined water level is reached, the water supply valve 22 is closed. The water supply is stopped (step S104).

次に、パルセータ8による攪拌が始まる(ステップS105)が、パルセータ8が回転すると、洗濯兼脱水槽7内および水槽3内の水は、下羽根18の回転による遠心力でポンプ室19から循環水路10を上昇し、上部吐出口11および中部吐出口12から洗濯兼脱水槽7内に向かって散水される。なお、パルセータ8が停止状態では、中部吐出口12は水中にあるが、パルセータ8が回転することにより、洗濯兼脱水槽7内の水位が下がるため、中部吐出口12は水面上に現れ、中部吐出口12からの吐出水も洗濯兼脱水槽7の内面をすすぎ、洗浄することができる。 Next, stirring by the pulsator 8 starts (step S105), but when the pulsator 8 rotates, the water in the washing / dehydrating tank 7 and the water tank 3 is circulated from the pump chamber 19 by the centrifugal force due to the rotation of the lower blade 18. 10 is raised, and water is sprinkled from the upper discharge port 11 and the middle discharge port 12 toward the inside of the washing / dehydrating tank 7. When the pulsator 8 is stopped, the central discharge port 12 is in water, but the rotation of the pulsator 8 lowers the water level in the washing / dehydrating tank 7, so that the central discharge port 12 appears on the water surface and is in the middle. The water discharged from the discharge port 12 can also be washed by rinsing the inner surface of the washing / dehydrating tank 7.

上部吐出口11および中部吐出口12から水をシャワー状に吐出させ、洗濯兼脱水槽7の内面に広範囲に渡って当てることによって、洗濯兼脱水槽7の内面をきれいに洗浄してすすぐことができる。なお、ON時間が短ければ、掻き揚げられる水量が少なく、吐出口に到達せずに終了してしまうため、パルセータ8の回転駆動時のON時間を長くとることにより、吐出する水量を増加させることが可能であり、ON時間は、実験によると2秒以上が望ましい。また、パルセータ8の回転駆動時の初期においては、水は勢いよく吐出されるが、その後、そのまま連続して回転し続けても、吐出される水の勢いは弱まり、広範囲に吐出し続けることができない。 By discharging water from the upper discharge port 11 and the middle discharge port 12 in a shower shape and applying it to the inner surface of the washing / dehydrating tub 7 over a wide area, the inner surface of the washing / dehydrating tub 7 can be cleaned and rinsed. .. If the ON time is short, the amount of water to be scooped up is small and the process ends without reaching the discharge port. Therefore, the amount of water to be discharged should be increased by lengthening the ON time when the pulsator 8 is rotationally driven. It is possible, and the ON time is preferably 2 seconds or more according to the experiment. Further, in the initial stage when the pulsator 8 is rotationally driven, water is discharged vigorously, but even if the pulsator 8 continues to rotate continuously thereafter, the momentum of the discharged water weakens and the water may continue to be discharged over a wide range. Can not.

そこで、パルセータ8の回転数を上げることで吐出範囲を狭めることなく連続して吐出することが可能である。パルセータ8の回転数は80r/min〜150r/minの範囲が望ましい。一例として、0〜0.6秒間で80r/min、0.6秒〜2秒で120r/minなどがある。初めから高い回転数で吐出した場合、吐出口が対抗する位置に配置されていた場合に、吐出水同士がぶつかり、内蓋29を設けない洗濯機の場合、水槽3外への水飛びに繋がる危険があり、吐出水がぶつからないように回転数を制御する。 Therefore, by increasing the rotation speed of the pulsator 8, it is possible to continuously discharge without narrowing the discharge range. The rotation speed of the pulsator 8 is preferably in the range of 80 r / min to 150 r / min. As an example, there are 80 r / min in 0 to 0.6 seconds, 120 r / min in 0.6 seconds to 2 seconds, and the like. When the water is discharged at a high rotation speed from the beginning, the discharged water collides with each other when the discharge ports are arranged at opposite positions, and in the case of a washing machine without an inner lid 29, it leads to water splashing to the outside of the water tank 3. There is a danger, and the rotation speed is controlled so that the discharged water does not collide.

パルセータ8による攪拌が第2の所定時間(例えば、1分)行われると、排水弁26が開き、水槽3内の水が機外へ排水される(ステップS106)。 When the stirring by the pulsator 8 is performed for a second predetermined time (for example, 1 minute), the drain valve 26 is opened and the water in the water tank 3 is drained to the outside of the machine (step S106).

また、排水途中の第3の所定水位(例えば、水位H1)において、モータ9が駆動して、排水しながら水と共に洗濯兼脱水槽7が第1の所定回転数(例えば、170r/min)で回転する槽回転を行う(ステップS107)。この槽回転による遠心力にて、水槽3と洗濯兼脱水槽7の間の水位を上昇させ、水槽3の内面および洗濯兼脱水槽7の外面に付着した汚れを洗い流すことができる。水槽3の内面および洗濯兼脱水槽7の外面を洗った水は、水槽3と洗濯兼脱水槽7の間から下へ落ちて、排水口25から排水弁26を介して機外へ排水される。なお、第3の所定水位は、上記のように、例えば、水位H1としたが、水槽3の内面および洗濯兼脱水槽7の外面を洗浄できる水量であればよい。但し、水量が多くなりすぎると、モータ9にかかる負荷が大きくなるので、好ましくない。 Further, at a third predetermined water level (for example, water level H1) during drainage, the motor 9 is driven, and the washing / dehydrating tank 7 is drained together with water at the first predetermined rotation speed (for example, 170 r / min). Rotate the tank (step S107). The centrifugal force generated by the rotation of the tank raises the water level between the water tank 3 and the washing / dehydrating tank 7, and can wash away the dirt adhering to the inner surface of the water tank 3 and the outer surface of the washing / dehydrating tank 7. The water that has washed the inner surface of the water tank 3 and the outer surface of the washing / dehydrating tank 7 falls down from between the water tank 3 and the washing / dehydrating tank 7, and is drained from the drain port 25 to the outside of the machine through the drain valve 26. .. The third predetermined water level is, for example, the water level H1 as described above, but it may be any amount of water that can wash the inner surface of the water tank 3 and the outer surface of the washing / dehydrating tank 7. However, if the amount of water is too large, the load applied to the motor 9 becomes large, which is not preferable.

その後、ブレーキによる反動での水飛びを防止するために、排水弁26を開いたままモータ9を停止して、洗濯兼脱水槽7を惰性回転させ、第2の所定回転数(例えば、35r/min以下)に低下したらブレーキをかける(ステップS108)。 After that, in order to prevent water from splashing due to the reaction caused by the brake, the motor 9 is stopped with the drain valve 26 open, and the washing / dehydrating tank 7 is inertially rotated to perform a second predetermined rotation speed (for example, 35r /). When it drops to min or less), the brake is applied (step S108).

そして、洗濯兼脱水槽7内、水槽3内に残る水滴を除去するために、モータ9が駆動して、洗濯兼脱水槽7を第3の所定回転数(例えば、780r/min)で高速回転させ、脱水を行ない(ステップS109)、第3の所定時間(例えば、0.5分)が経過すると、洗濯兼脱水槽7の回転を終了し、槽すすぎコースが終了する(ステップS110)。 Then, in order to remove the water droplets remaining in the washing / dehydrating tank 7 and the water tank 3, the motor 9 is driven to rotate the washing / dehydrating tank 7 at a high speed at a third predetermined rotation speed (for example, 780 r / min). And dehydration is performed (step S109), and when the third predetermined time (for example, 0.5 minutes) elapses, the rotation of the washing / dehydrating tub 7 is completed, and the tub rinsing course is completed (step S110).

[1-3. Effect, etc.]
As described above, in the present embodiment, the washing machine 1 includes a main body 2, a water tank 3 in which the main body 2 is supported by hanging vibration isolation, and a washing / dehydrating tank 7 rotatably contained in the water tank 3. Water is supplied to the pulsator 8 which is rotatably arranged at the central inner bottom of the washing / dehydrating tub 7 and has a plurality of lower blades formed on the back surface side, the motor 9 which drives the pulsator 8 and the washing / dehydrating tub 7 to rotate, and the water tub 3. Water supply valve 22 for draining water in the water tank 3, a drain valve 26 for draining water in the water tank 3, and an operation means for selecting and inputting an operation course mode and various functions arranged on an upper frame 21 provided on the upper part of the main body 2. An operation display unit 23 having a display means for displaying the input information and the like, a circulation water channel cover 14 provided facing the inner wall of the washing / dehydrating tub 7 and formed in a vertically long shape, and a washing / dehydrating tub 7 The circulation water channel 10 formed by the circulation water channel cover 14, the pump chamber 19 formed in the inner bottom of the washing / dehydrating tank 7 and accommodating the lower blades of the pulsator 8, and the pulsator 8 formed in the circulation water channel cover 14. The operation of the upper discharge port 11 and the motor 9, the water supply valve 22, the drain valve 26, etc., in which the water that has reached the circulation water channel 10 from the 19 pump chamber due to rotation is discharged in a wide angle into the washing / dehydrating tank 7, is controlled. It is provided with a control means for controlling each process of washing, rinsing, and dehydration. The control means enables the rinsing tank rinsing course of the water tank 3 and the washing / dehydrating tank 7 to be executed, and the tank rinsing course rotates the pulsator 8 at a predetermined water level at a predetermined rotation speed and discharges water from the upper discharge port 11. By doing so, the inner surface of the washing / dehydrating tub 7 is rinsed, and then the washing / dehydrating tub 7 is drained while rotating at a predetermined rotation speed so that the outer surface of the washing / dehydrating tub 7 and the inner surface of the water tub 3 are rinsed. It was done.

これにより、槽すすぎコースは、所定水位においてパルセータ8を所定の回転数で回転させ、上部吐出口11より水を吐出することで、洗濯兼脱水槽7の内面をすすぎ、その後、洗濯兼脱水槽7を所定の回転数で回転しながら排水することで、洗濯兼脱水槽7の外面および水槽3の内面をすすぐことができる。そのため、専用のコースとして、少ない水で、水飛びを防止しつつ、水槽3の内面、洗濯兼脱水槽7の内面、外面を効果的にすすぐことができ、清潔感を向上させ、使用者の要求を満足させることができる。 As a result, in the tub rinsing course, the pulsator 8 is rotated at a predetermined rotation speed at a predetermined water level, and water is discharged from the upper discharge port 11 to rinse the inner surface of the washing / dehydrating tub 7 and then the washing / dehydrating tub. By draining water while rotating 7 at a predetermined rotation speed, the outer surface of the washing / dehydrating tub 7 and the inner surface of the water tub 3 can be rinsed. Therefore, as a dedicated course, it is possible to effectively rinse the inner surface of the water tank 3 and the inner and outer surfaces of the washing / dehydrating tank 7 with a small amount of water while preventing water from splashing, improving the cleanliness and improving the cleanliness of the user. Can satisfy the demand.

本実施の形態のように、洗濯機1における制御手段は、すすぎコースの所定水位においてパルセータ8を所定の回転数で回転させる際、パルセータ8の回転駆動時のON時間を衣類洗濯時のON時間より長くするとともに、パルセータ8の回転数を回転途中で上昇させるようにしたようにしてもよい。 As in the present embodiment, when the control means in the washing machine 1 rotates the pulsator 8 at a predetermined rotation speed at a predetermined water level of the rinsing course, the ON time when the pulsator 8 is driven to rotate is set to the ON time when washing clothes. In addition to making it longer, the rotation speed of the pulsator 8 may be increased during the rotation.

これにより、パルセータ8の下羽根で掻き揚げられたすすぎ水を、ポンプ室19から循環水路10を通して、洗濯兼脱水槽7の内方に吐出する水量を増加させることが可能となる。通常の洗濯時にパルセータ8のON時間を延ばして、洗濯兼脱水槽7の内面をすすぐのは、パルセータ8の回転により衣類が勢いよく回りすぎ、水飛びしやすくなる課題と、すすぐことで浮遊した汚れが衣類に付着してしまうために、通常の洗濯とは分けた槽すすぎコースを持つことが重要である。ON時間が短ければ、掻き揚げられる水量が少なく、上部吐出口11に到達せずに終了してしまうといった現象が発生してしまう。また、パルセータ8の回転駆動時の初期においては、水は勢いよく吐出されるが、その後、そのままパルセータ8を連続して回転し続けても吐出される勢いは弱まり、広範囲に吐出し続けることができない。そこで、パルセータ8の回転数を回転途中で上昇させることで範囲を狭めることなく連続して吐出することが可能となる。なお、初めから高い回転数で吐出した場合、上部吐出口11が対向して設けられているので、吐出水同士がぶつかり、機外への水飛びに繋がる危険があり、回転駆動時は、吐出水がぶつからない回転数に設定し、その後、回転数を上昇させることで、吐出水がぶつからず、また、連続して吐出水を吐出させることができる。 As a result, it is possible to increase the amount of water discharged from the pump chamber 19 to the inside of the washing / dehydrating tank 7 through the circulation water channel 10 from the rinse water scooped up by the lower blades of the pulsator 8. Extending the ON time of the pulsator 8 during normal washing and rinsing the inner surface of the washing and dehydration tub 7 is a problem that clothes rotate too vigorously due to the rotation of the pulsator 8 and it becomes easy for water to splash, and it floats by rinsing. It is important to have a tub rinsing course separate from normal washing, as dirt will adhere to the clothes. If the ON time is short, the amount of water that can be scooped up is small, and a phenomenon occurs in which the operation ends without reaching the upper discharge port 11. Further, in the initial stage when the pulsator 8 is rotationally driven, water is discharged vigorously, but after that, even if the pulsator 8 is continuously rotated, the discharged momentum weakens and the water may be continuously discharged over a wide range. Can not. Therefore, by increasing the rotation speed of the pulsator 8 in the middle of rotation, it is possible to continuously discharge the pulsator 8 without narrowing the range. When discharging at a high rotation speed from the beginning, since the upper discharge ports 11 are provided facing each other, there is a risk that the discharged waters may collide with each other and lead to water splashing to the outside of the machine. By setting the rotation speed so that the water does not collide and then increasing the rotation speed, the discharged water does not collide and the discharged water can be continuously discharged.

本実施の形態のように、洗濯機1における吐出部は、循環水路10の上部に上部吐出口11と中部に設けた中部吐出口12としてもよい。 As in the present embodiment, the discharge portion in the washing machine 1 may be an upper discharge port 11 provided in the upper part of the circulation water channel 10 and a middle discharge port 12 provided in the middle part.

これにより、洗濯兼脱水槽7の内面上部から内面中部と、内面中部から内面下部とをそれぞれすすぐことができるので、内面の上から下の全面にわたってすすぐことができる。そのため、清潔感を向上させ、使用者の要求を満足させることができる。 As a result, it is possible to rinse from the upper part of the inner surface to the middle part of the inner surface and from the middle part of the inner surface to the lower part of the inner surface of the washing / dehydrating tub 7, so that it is possible to rinse the entire surface from the upper part to the lower part of the inner surface. Therefore, the feeling of cleanliness can be improved and the demand of the user can be satisfied.
