次に、洗濯機１０の制御系の構成例について説明する。図２に例示する制御装置２０は、制御手段の一例であり、例えばマイクロコンピュータを主体として構成されている。制御装置２０は、制御プログラムを実行することにより、駆動装置１４による回転槽１３やパルセータ１３ａの回転動作、給水機構部１５による給水動作、排水機構部１６による排水動作など、洗濯機１０の動作全般を制御する。具体的には、制御装置２０は、駆動装置１４、給水弁１５ａ、排水弁１６ａなどの駆動を制御することにより、回転槽１３内の衣類を洗う洗い行程、回転槽１３内の衣類をすすぐすすぎ行程、回転槽１３内の衣類を脱水する脱水行程を含む一連の洗濯運転を実行可能となっている。 Next, a configuration example of the control system of the washing machine 10 will be described. The control device 20 illustrated in FIG. 2 is an example of control means, and is mainly composed of a microcomputer, for example. By executing the control program, the control device 20 performs general operations of the washing machine 10, such as rotation of the rotary tub 13 and the pulsator 13a by the driving device 14, water supply by the water supply mechanism 15, and drainage by the drainage mechanism 16. to control. Specifically, the control device 20 controls driving of the driving device 14, the water supply valve 15a, the drain valve 16a, etc., so that the washing process for washing the clothes in the rotary tub 13, the rinsing process for rinsing the clothes in the rotary tub 13, etc. A series of washing operations including a dehydration process for dehydrating the clothes in the rotary tub 13 can be executed.

本実施形態に係る洗濯機１０には、洗濯運転における排水行程とその後の脱水行程との間において、回転槽１３内の衣類が飛び跳ねるような挙動を示すことを抑制するための創意工夫が施されている。以下、この点について詳細に説明する。 The washing machine 10 according to the present embodiment is designed to prevent the clothes in the rotating tub 13 from jumping between the draining process and the subsequent dehydrating process in the washing operation. ing. This point will be described in detail below.

図３に例示するように、洗濯機１０の制御装置２０は、回転槽１３内の衣類を洗う洗い行程の後に、水槽１２内の水を排出する排水行程、衣類飛び跳ね防止行程、第１脱水行程、ためすすぎ行程、第２脱水行程を順次実行するように構成されている。 As exemplified in FIG. 3, the control device 20 of the washing machine 10 performs a washing process for washing the clothes in the rotating tub 13, a draining process for discharging the water in the water tank 12, a clothes splash prevention process, and a first dehydration process. , a preliminary rinsing process, and a second dewatering process are sequentially executed.

ここで、洗い行程は、給水機構部１５により水槽１２内に所定の洗い用の水量を供給してパルセータ１３ａを所定の洗い用回転速度で正転方向および逆転方向に適宜切り換えながら回転させることにより、回転槽１３内の衣類を洗う周知の行程である。なお、所定の洗い用の水量は、例えば、回転槽１３内に収容されている衣類の重量、使用者によって設定された設定水量などに応じて、適宜変更して設定することができる。また、所定の洗い用回転速度は、例えば、使用者によって設定された運転コースの種類などに応じて、適宜変更して設定することができる。 Here, the washing process is performed by supplying a predetermined amount of water for washing into the water tub 12 from the water supply mechanism 15 and rotating the pulsator 13a at a predetermined rotational speed for washing while appropriately switching between the forward rotation direction and the reverse rotation direction. , are well-known processes for washing the clothes in the rotating tub 13 . It should be noted that the predetermined amount of water for washing can be appropriately changed and set according to, for example, the weight of the clothes accommodated in the rotating tub 13 and the set amount of water set by the user. Further, the predetermined rotation speed for washing can be appropriately changed and set according to, for example, the type of operation course set by the user.

なお、回転槽１３内に収容されている衣類の重量検知は、例えば、パルセータ１３ａを所定の重量検知用の回転速度で回転させた場合における駆動装置１４のモータの電流値の変動に基づき衣類の重量を判定する手法、回転槽１３を含む水槽１２の重量の変動を測定する重量測定器による手法など、周知の手法を適宜採用することができる。 The weight of the clothes contained in the rotating tub 13 is detected based on the fluctuation of the current value of the motor of the driving device 14 when the pulsator 13a is rotated at a predetermined rotation speed for weight detection, for example. Well-known methods such as a method of determining the weight and a method of using a weight measuring device for measuring fluctuations in the weight of the water tank 12 including the rotating tank 13 can be employed as appropriate.

また、排水行程は、給水機構部１５による水槽１２内への給水動作を停止した状態で、排水弁１６ａを開くことにより、水槽１２内の水を機外に排出する行程である。 The draining process is a process of discharging the water in the water tank 12 to the outside of the apparatus by opening the drain valve 16a while the water supply mechanism 15 stops supplying water to the water tank 12. FIG.

また、第１脱水行程は、給水機構部１５による水槽１２内への給水動作を停止し、且つ、水槽１２内の水を機外に排出した状態で回転槽１３を所定の脱水用回転速度で一方向に回転させることにより、回転槽１３内の衣類を脱水する周知の行程である。この場合、第１脱水行程における所定の脱水用回転速度は、所定の洗い用回転速度よりも高速である例えば７００ｒｐｍで設定されている。 In the first dehydration process, the operation of supplying water into the water tank 12 by the water supply mechanism 15 is stopped, and the water in the water tank 12 is discharged to the outside of the apparatus, and the rotary tank 13 is rotated at a predetermined rotational speed for dehydration. This is a well-known process for dehydrating the clothes in the rotating tub 13 by rotating them in one direction. In this case, the predetermined rotation speed for dehydration in the first dehydration process is set at, for example, 700 rpm, which is higher than the predetermined rotation speed for washing.

また、第２脱水行程は、給水機構部１５による水槽１２内への給水動作を停止し、且つ、水槽１２内の水を機外に排出した状態で回転槽１３を所定の脱水用回転速度で一方向に回転させることにより、回転槽１３内の衣類を脱水する周知の行程である。この場合、第２脱水行程における所定の脱水用回転速度は、第１脱水行程における所定の脱水用回転速度と同じである例えば７００ｒｐｍで設定されている。なお、第２脱水行程における所定の脱水用回転速度は、第１脱水行程における所定の脱水用回転速度と異なる回転速度であってもよい。 In the second dehydration process, the operation of supplying water into the water tank 12 by the water supply mechanism 15 is stopped, and the water in the water tank 12 is discharged to the outside of the machine, and the rotary tank 13 is rotated at a predetermined rotational speed for dehydration. This is a well-known process for dehydrating the clothes in the rotating tub 13 by rotating them in one direction. In this case, the predetermined dehydration rotation speed in the second dehydration process is set at, for example, 700 rpm, which is the same as the predetermined dehydration rotation speed in the first dehydration process. The predetermined spin speed for dewatering in the second dewatering process may be a different spin speed from the predetermined spin speed for dewatering in the first dewatering process.

また、ためすすぎ行程は、給水機構部１５により水槽１２内に所定のためすすぎ用の水量を供給してパルセータ１３ａを所定のためすすぎ用回転速度で正転方向および逆転方向に適宜切り換えながら回転させることにより、回転槽１３内の衣類をすすぐ周知の行程である。本実施形態では、ためすすぎ行程は、第１脱水行程の後であって、且つ、第２脱水行程の前、つまり、第１脱水行程と第２脱水行程との間に実行されるようになっている。なお、ためすすぎ用の水量は、適宜変更して設定することができ、例えば、洗い行程における所定の洗い用の水量と同じ水量としてもよいし、異なる水量としてもよい。また、所定のためすすぎ用回転速度は、適宜変更して設定することができ、例えば、洗い行程における所定の洗い用回転速度と同じ回転速度としてもよいし、異なる回転速度としてもよい。 In the rinsing step, a predetermined amount of water for rinsing is supplied into the water tank 12 by the water supply mechanism 15, and the pulsator 13a is rotated at a predetermined rotational speed for rinsing while appropriately switching between the forward rotation direction and the reverse rotation direction. This is a well-known process for rinsing the clothes in the rotating tub 13 by washing. In this embodiment, the preliminary rinsing process is performed after the first dehydration process and before the second dehydration process, that is, between the first dehydration process and the second dehydration process. ing. The amount of water for preliminary rinsing can be changed and set as appropriate. For example, it may be the same amount of water as the predetermined amount of water for washing in the washing process, or it may be a different amount of water. Further, the predetermined rotation speed for rinsing can be changed and set as appropriate. For example, it may be set to the same rotation speed as the predetermined rotation speed for washing in the washing process, or may be set to a different rotation speed.

また、制御装置２０は、ためすすぎ行程において、回転槽１３内の衣類をほぐすためのほぐし動作を実行可能に構成されている。ほぐし動作は、例えば、水槽１２内に所定のほぐし動作用の水量を溜めた状態でパルセータ１３ａを所定のほぐし動作用の回転速度で正転方向および逆転方向に適宜切り換えながら回転させることにより、回転槽１３内の衣類をほぐす周知の動作である。なお、所定のほぐし動作用の水量は、適宜変更して設定することができ、所定のほぐし動作用の回転速度は、適宜変更して設定することができる。また、制御装置２０は、このほぐし動作を実行するか否かを適宜切り換えることができるように構成されている。 Further, the control device 20 is configured to be able to perform a loosening operation for loosening the clothes in the rotary tub 13 in the preliminary rinsing process. The loosening operation is performed, for example, by rotating the pulsator 13a at a predetermined rotational speed for loosening operation while appropriately switching between forward and reverse rotation directions while a predetermined amount of water for loosening operation is stored in the water tank 12. This is a well-known operation for loosening the clothes in tub 13 . The amount of water for the predetermined loosening operation can be appropriately changed and set, and the rotation speed for the predetermined loosening operation can be appropriately changed and set. In addition, the control device 20 is configured to be able to appropriately switch whether or not to perform this loosening operation.

そして、本実施形態では、衣類飛び跳ね防止行程は、上述した排水行程の後であって、且つ、第１脱水行程の前、つまり、排水行程と第１脱水行程との間に実行されるようになっている。次に、この衣類飛び跳ね防止行程について説明する。衣類飛び跳ね防止行程は、第１すすぎ動作、低速脱水動作、第２すすぎ動作を含む行程となっている。 Further, in the present embodiment, the clothes splash prevention process is executed after the above-described draining process and before the first spin-drying process, that is, between the draining process and the first spin-drying process. It's becoming Next, this clothing jump prevention process will be described. The clothes jumping prevention process is a process including a first rinsing operation, a low-speed dehydration operation, and a second rinsing operation.

第１すすぎ動作は、回転槽１３を正転方向、または逆転方向に回転させながら給水機構部１５により回転槽１３内、特に回転槽１３内の縁部に水を供給する動作である。回転槽１３内の縁部に水が供給されることにより、回転槽１３内の衣類、特に回転槽１３の縁部に存在する衣類を、その供給される水によって上方から押えることができる。また、回転槽１３内の衣類に適度に水を浸み込ませて重量を増加させることができる。そのため、回転槽１３の回転に伴い衣類が飛び跳ねるような挙動を示すことを抑制することができる。 The first rinsing operation is an operation in which water is supplied to the inside of the rotary tub 13 , especially to the edge of the rotary tub 13 by the water supply mechanism 15 while rotating the rotary tub 13 in the normal direction or the reverse direction. By supplying water to the edge of the rotating tub 13, the clothes in the rotating tub 13, especially the clothing existing at the edge of the rotating tub 13, can be pressed from above by the supplied water. Also, the clothes in the rotating tub 13 can be soaked with water to increase the weight. Therefore, it is possible to prevent the clothes from jumping as the rotary tub 13 rotates.

低速脱水動作は、第１すすぎ動作の後に実行される動作であり、給水機構部１５による給水動作を停止した状態で回転槽１３を低速回転速度で一方向に回転させる動作である。低速回転速度は、上述した第１脱水行程における脱水用回転速度および第２脱水行程における脱水用回転速度よりも低い回転速度において、適宜変更して設定することができる。本実施形態では、低速回転速度として、例えば４００ｒｐｍが設定されている。このように低速で回転槽１３が回転する低速脱水動作によれば、上述した第１脱水行程および第２脱水行程よりも衣類に作用する外力を低減させることができる。そのため、回転槽１３の回転に伴い衣類が飛び跳ねるような挙動を示すことを抑制することができる。 The low-speed dehydration operation is an operation performed after the first rinsing operation, and is an operation of rotating the rotary tub 13 in one direction at a low rotational speed while the water supply operation by the water supply mechanism 15 is stopped. The low-speed rotation speed can be appropriately changed and set to a rotation speed lower than the dehydration rotation speed in the first dehydration process and the dehydration rotation speed in the second dehydration process. In this embodiment, for example, 400 rpm is set as the low rotational speed. According to the low-speed dehydration operation in which the rotary tub 13 rotates at a low speed in this manner, the external force acting on the clothes can be reduced more than in the first dehydration process and the second dehydration process described above. Therefore, it is possible to prevent the clothes from jumping as the rotary tub 13 rotates.

第２すすぎ動作は、低速脱水行程の後に実行される動作であり、回転槽１３を正転方向、または逆転方向に回転させながら給水機構部１５により回転槽１３内、特に回転槽１３の縁部に水を供給する動作である。回転槽１３内の縁部に水が供給されることにより、回転槽１３内の衣類、特に上述の低速脱水動作によって回転槽１３の縁部に偏在するようになった衣類を、回転槽１３の中央に向けて押し戻すことができる。そのため、回転槽１３の縁部に衣類が偏った状態が解消され、回転槽１３の回転に伴い衣類が飛び跳ねるような挙動を示すことを抑制することができる。 The second rinsing operation is an operation performed after the low-speed dehydration process, in which the inside of the rotary tub 13, particularly the edge of the rotary tub 13, is rinsed by the water supply mechanism 15 while the rotary tub 13 is rotated in the forward or reverse direction. This is the action of supplying water to the By supplying water to the edge of the rotating tub 13, the clothes in the rotating tub 13, especially the clothes that are unevenly distributed at the edge of the rotating tub 13 due to the above-described low-speed dehydration operation, are removed from the rotating tub 13. You can push it back toward the center. Therefore, the state in which the clothes are biased toward the edge of the rotary tub 13 is eliminated, and it is possible to prevent the clothes from jumping as the rotary tub 13 rotates.

本実施形態に係る洗濯機１０によれば、制御装置２０は、排水行程と第１脱水行程との間に衣類飛び跳ね防止行程を実行するように構成されている。そして、その衣類飛び跳ね防止行程において、制御装置２０は、第１すすぎ動作を実行し、その後、低速脱水動作を実行し、その後、第２すすぎ動作を実行する。 According to the washing machine 10 according to this embodiment, the control device 20 is configured to execute the clothes splash prevention process between the draining process and the first spin-drying process. Then, in the clothes jumping prevention process, the control device 20 performs the first rinsing operation, then the low-speed dehydration operation, and then the second rinsing operation.

第１すすぎ動作においては、上述した通り、供給される水によって回転槽１３内の衣類を上方から押えることができるから、回転槽１３の回転に伴い衣類が飛び跳ねるような挙動を示すことを抑制することができる。また、低速脱水動作においては、上述した通り、回転槽１３内の衣類に作用する外力を低減させることができるから、回転槽１３の回転に伴い衣類が飛び跳ねるような挙動を示すことを抑制することができる。また、第２すすぎ動作においては、上述した通り、回転槽１３内に供給される水によって回転槽１３の縁部に衣類が偏った状態を解消させることができるから、回転槽１３の回転に伴い衣類が飛び跳ねるような挙動を示すことを抑制することができる。 In the first rinsing operation, as described above, the clothes in the rotary tub 13 can be pressed from above by the supplied water, so that the clothes are prevented from jumping as the rotary tub 13 rotates. be able to. In addition, in the low-speed dehydration operation, as described above, the external force acting on the clothes in the rotary tub 13 can be reduced, so that it is possible to prevent the clothes from jumping as the rotary tub 13 rotates. can be done. In addition, in the second rinsing operation, as described above, the water supplied into the rotary tub 13 can eliminate the state in which the clothes are biased toward the edges of the rotary tub 13. Therefore, as the rotary tub 13 rotates, It is possible to suppress the clothing from exhibiting a jumping behavior.

以上の通り、衣類飛び跳ね防止行程によれば、回転槽１３の回転に伴い衣類が飛び跳ねるような挙動を示すことを抑制しつつ、排水行程後の衣類を脱水することができる。つまり、本実施形態に係る洗濯機１０によれば、排水行程とその後の第１脱水行程との間に実行する行程において、衣類が飛び跳ねるような挙動を示すことを抑制することができる。 As described above, according to the clothes jumping prevention process, it is possible to dehydrate the clothes after the draining process while preventing the clothes from jumping as the rotary tub 13 rotates. That is, according to the washing machine 10 of the present embodiment, it is possible to prevent the clothes from jumping in the process performed between the draining process and the subsequent first spin-drying process.

なお、洗濯機１０は、回転槽１３内の衣類の重量が所定の基準量以上である場合に衣類飛び跳ね防止行程を実行するように構成してもよい。即ち、回転槽１３内に収容されている衣類の量が多いほど、回転槽１３の回転に伴い衣類が飛び跳ねるような挙動を示しやすくなり、場合によっては、回転槽１３の外部に飛び出してしまうことも懸念される。そのため、回転槽１３内の衣類の重量が所定の基準量以上である場合、つまり、回転槽１３内の衣類が多量である場合に衣類飛び跳ね防止行程を実行するようにすることで、この衣類飛び跳ね防止行程による効果、つまり、衣類が飛び跳ねるような挙動を示すことを抑制するという効果を有効に活用することができる。なお、所定の基準量は、例えば、回転槽１３内に収容可能な衣類の重量の上限である最大容量に近い容量、例えば、最大容量の６０～８０パーセント程の容量を設定するなど、適宜変更して設定することができる。 Washing machine 10 may be configured to perform the step of preventing clothes from jumping when the weight of clothes in rotating tub 13 is equal to or greater than a predetermined reference weight. That is, as the amount of clothes stored in the rotary tub 13 increases, the clothes tend to jump as the rotary tub 13 rotates. is also of concern. Therefore, when the weight of the clothes in the rotary tub 13 is equal to or greater than a predetermined reference amount, that is, when the amount of clothes in the rotary tub 13 is large, the step of preventing the clothes from jumping is executed to prevent the clothes from jumping. It is possible to effectively utilize the effect of the prevention process, that is, the effect of suppressing the jumping behavior of the clothes. The predetermined reference amount may be changed as appropriate, for example, by setting a capacity close to the maximum capacity, which is the upper limit of the weight of clothes that can be accommodated in the rotating tub 13, for example, setting a capacity of about 60 to 80% of the maximum capacity. can be set as

また、洗濯機１０は、衣類飛び跳ね防止行程において、第１すすぎ動作の動作内容と第２すすぎ動作の内容とを異ならせるようにしてもよい。具体的には、第１すすぎ動作および第２すすぎ動作における回転槽１３の回転速度、回転方向、給水機構部１５による給水量、実行時間などを相互に異ならせるようにするとよい。ここで、第２すすぎ動作においては、後続の第１脱水行程に備え、回転槽１３内における衣類の偏りを十分に解消することが求められる。そのため、第２すすぎ動作における回転槽１３の回転速度を第１すすぎ動作よりも低速にしたり、第２すすぎ動作における給水量を第１すすぎ動作よりも多くしたり、第２すすぎ動作の実行時間を第１すすぎ動作の実行時間よりも長くしたり、回転槽１３の回転方向を第１すすぎ動作と第２すすぎ動作とで異ならせたりすると有効である。 Further, in the washing machine 10, the contents of the first rinsing operation and the contents of the second rinsing operation may be different in the clothes jumping prevention process. Specifically, the rotation speed, rotation direction, amount of water supplied by the water supply mechanism 15, execution time, etc. of the rotary tub 13 in the first rinsing operation and the second rinsing operation may be made different from each other. Here, in the second rinsing operation, in preparation for the subsequent first dehydration process, it is required to sufficiently eliminate unevenness of the clothes in the rotating tub 13 . Therefore, the rotation speed of the rotary tub 13 in the second rinsing operation is set lower than that in the first rinsing operation, the amount of water supply in the second rinsing operation is set higher than that in the first rinsing operation, and the execution time of the second rinsing operation is It is effective to make the execution time of the first rinsing operation longer than that of the first rinsing operation, or to change the direction of rotation of the rotary tub 13 between the first rinsing operation and the second rinsing operation.

また、洗濯機１０は、衣類飛び跳ね防止行程を実行した場合には、ためすすぎ行程におけるほぐし動作の内容を、衣類飛び跳ね防止行程を実行していない場合と異ならせるようにしてもよい。具体的には、衣類飛び跳ね防止行程を実行した場合と実行していない場合とで、ほぐし動作におけるパルセータ１３ａの回転速度、回転方向、給水機構部１５による給水量、実行時間などを相互に異ならせるようにするとよい。ここで、衣類飛び跳ね防止行程を実行した場合には、複数回のすすぎ動作を経由しているため、回転槽１３内の衣類の絡み合いが比較的少なくなった状態となっている。また、後続の第２脱水行程においては、衣類がほぐれていると衣類が飛び出してしまうおそれがあり、適度に衣類が絡み合っていた方がよい。そのため、衣類飛び跳ね防止行程を実行した場合には、ほぐし動作におけるパルセータ１３ａの回転速度を衣類飛び跳ね防止行程を実行していない場合よりも低速にしたり、ほぐし動作の実行時間を衣類飛び跳ね防止行程を実行していない場合よりも短くしたり、ほぐし動作におけるパルセータ１３ａの回転方向を単一方向にしたりすると有効である。また、洗濯機１０は、衣類飛び跳ね防止行程を実行した場合には、ためすすぎ行程においてほぐし動作を実行しないようにしてもよい。 Further, when the washing machine 10 executes the clothes jumping prevention process, the contents of the loosening operation in the rinsing process may be different from those when the clothes jumping prevention process is not executed. Specifically, the rotation speed and rotation direction of the pulsator 13a, the amount of water supplied by the water supply mechanism 15, the execution time, etc. of the loosening operation are made different between when the clothes jumping prevention process is executed and when it is not executed. It is better to Here, when the clothes jumping prevention process is executed, since the rinsing operation has been performed a plurality of times, the tangling of the clothes in the rotary tub 13 is relatively reduced. Further, in the subsequent second dehydration process, if the clothes are unraveled, the clothes may jump out, so it is preferable that the clothes are properly entangled. Therefore, when the clothes jumping prevention process is executed, the rotation speed of the pulsator 13a in the loosening operation is set to be lower than that in the case where the clothes jumping prevention process is not executed, or the execution time of the loosening operation is set to the clothes jumping prevention process. It is effective to make the pulsator 13a shorter than when it is not used or to rotate the pulsator 13a in a single direction during the loosening operation. Further, the washing machine 10 may not perform the loosening operation in the rinsing process when the clothes jumping prevention process is performed.

For example, the washing machine 10 may perform the clothes splash prevention process multiple times between the draining process and the first spin-drying process. Moreover, the water supply into the rotating tub 13 in the first rinsing operation and the second rinsing operation may be performed in a shower-like manner. Further, the water supply into the rotating tub 13 in the first rinsing operation and the second rinsing operation may be performed toward other than the edge portion of the rotating tub 13 . Moreover, the washing machine 10 may be configured to include an inner lid.
