The configuration will be described below.

従来の洗濯機は、水受け槽１０１と水受け槽１０１の内部に回転自在に配設されている洗濯兼脱水槽１０３を備えている。水受け槽１０１はサスペンション１０４を介して防振支持されている。洗濯兼脱水槽１０３内には、洗濯物１１３と洗剤１１４が投入され、洗濯液が所定水位まで入れられる。洗濯兼脱水槽１０３の上部にはバランサー１１０が設けられている。洗濯兼脱水槽１０３の内底部には回転自在にパルセータ１０２が設けられている。水受け槽１０１の底面には、洗濯兼脱水槽１０３および／またはパルセータ１０２を駆動するモータ１０６が配設されている。モータ１０６は、駆動の切換を行うクラッチ機構１０７を介して、洗濯兼脱水槽１０３および／またはパルセータ１０２を駆動する。洗濯兼脱水槽１０３の上部には、給水口１１７が設けられている。制御装置１１６は、モータ１０６、排水弁１０８、および、給水弁１０９の動作を制御し、洗い、すすぎ、脱水などの一連の工程を逐次制御する。 A conventional washing machine includes a water receiving tub 101 and a washing / dehydrating tub 103 that is rotatably arranged inside the water receiving tub 101. The water receiving tank 101 is vibration-proof supported via the suspension 104. The laundry 113 and the detergent 114 are put into the washing / dehydrating tub 103, and the washing liquid is put into a predetermined water level. A balancer 110 is provided above the washing / dehydrating tub 103. A pulsator 102 is rotatably provided on the inner bottom of the washing / dehydrating tub 103. On the bottom surface of the water receiving tank 101, a motor 106 for driving the washing / dehydrating tank 103 and / or the pulsator 102 is arranged. The motor 106 drives the washing / dehydrating tub 103 and / or the pulsator 102 via a clutch mechanism 107 that switches the drive. A water supply port 117 is provided above the washing / dehydrating tub 103. The control device 116 controls the operation of the motor 106, the drain valve 108, and the water supply valve 109, and sequentially controls a series of steps such as washing, rinsing, and dehydration.

次に、従来の洗濯機の動作（洗濯運転）を説明する。洗濯兼脱水槽１０３内に洗濯物１１３と洗剤１１４が投入され、洗濯液が所定水位まで入れられる。そして、制御装置１１６によりモータ１０６が回転駆動され、洗濯兼脱水槽１０３および／またはパルセータ１０２が回転して、洗濯物１１３に付着した汚れを落す、洗い工程が行われる。 Next, the operation of the conventional washing machine (washing operation) will be described. The laundry 113 and the detergent 114 are put into the washing / dehydrating tub 103, and the washing liquid is put into a predetermined water level. Then, the motor 106 is rotationally driven by the control device 116, and the washing / dehydrating tub 103 and / or the pulsator 102 is rotated to perform a washing step of removing dirt adhering to the laundry 113.

つぎに、洗濯物１１３に残留付着した洗剤１１４成分を取り除くために、汚れおよび洗剤１１４成分を含んだ洗濯液が一度排水され、再び給水が行われる。そして、洗濯兼脱水槽１０３および／またはパルセータ１０２が回転して、洗濯物１１３から洗剤１１４成分を取り除く、すすぎ工程が行われる。すすぎ工程終了後は、制御装置１１６は、すすぎ工程に使った洗濯液を排水し、洗濯兼脱水槽１０３を回転させ、遠心力によって洗濯物１１３に含まれた洗濯液を排出する脱水工程を行う。 Next, in order to remove the detergent 114 component remaining on the laundry 113, the washing liquid containing the dirt and the detergent 114 component is drained once, and water is supplied again. Then, the washing / dehydrating tub 103 and / or the pulsator 102 is rotated to perform a rinsing step of removing the detergent 114 component from the laundry 113. After the rinsing step is completed, the control device 116 drains the washing liquid used in the rinsing step, rotates the washing / dehydrating tub 103, and performs a dehydration step of discharging the washing liquid contained in the laundry 113 by centrifugal force. ..

当該従来の洗濯機においては、図９に示すように、制御装置１１６は、すすぎ工程の終わりにおいて、洗濯液の排水の途中に所定水位で排水を止め、再度、洗濯兼脱水槽１０３の回転によって、水受け槽１０１の洗濯液に遠心力を作用させ、洗濯液を撹乱させる撹乱工程を実行する。撹乱工程においては、洗濯兼脱水槽１０３と水受け槽１０１の間の洗濯液が撹乱されて、洗濯兼脱水槽１０３の外面と水受け槽１０１の内面の壁面に吸着して残っていた洗剤カス１１５が撹乱の水流の力により除去される。 In the conventional washing machine, as shown in FIG. 9, at the end of the rinsing process, the control device 116 stops the drainage at a predetermined water level during the drainage of the washing liquid, and again by rotating the washing / dehydrating tub 103. , Centrifugal force is applied to the washing liquid in the water receiving tank 101 to perform a disturbing step of disturbing the washing liquid. In the disturbing step, the washing liquid between the washing / dehydrating tub 103 and the water receiving tub 101 is disturbed, and the detergent residue remaining adsorbed on the outer surface of the washing / dehydrating tub 103 and the inner wall surface of the water receiving tub 101. 115 is removed by the force of the disturbing water stream.

また、制御装置１１６は、洗濯兼脱水槽１０３と水受け槽１０１の間の洗濯液を撹乱する撹乱工程にて、図１０（ａ）に示すように、洗濯兼脱水槽１０３を回転数Ｎにて回転させている途中から、図１０（ｂ）に示すように、排水弁１０８をオンして洗濯液の排水を始め、洗濯兼脱水槽１０３を回転しながら排水するように制御する。さらに、図１０（ｃ）に示すように、制御装置１１６は、洗濯兼脱水槽１０３を回転数Ｎにて回転させている
途中から、給水弁１０９をオンして給水するように構成されている。 Further, in the disturbing step of disturbing the washing liquid between the washing / draining tub 103 and the water receiving tub 101, the control device 116 sets the washing / draining tub 103 to the rotation speed N as shown in FIG. 10 (a). As shown in FIG. 10B, the drain valve 108 is turned on to start draining the washing liquid from the middle of the rotation, and the washing / dehydrating tank 103 is controlled to be drained while rotating. Further, as shown in FIG. 10C, the control device 116 is configured to turn on the water supply valve 109 to supply water while the washing / dehydrating tub 103 is being rotated at the rotation speed N. ..

上記従来の洗濯機は、洗濯兼脱水槽１０３の外面と水受け槽１０１の内面の壁面に吸着して残っていた洗剤カス１１５を除去するために撹乱工程を実行する。このため、洗濯兼脱水槽１０３内の洗濯物１１３のバランスが悪い場合には、制御装置１１６が洗濯兼脱水槽１０３を回転させると、洗濯兼脱水槽１０３が激しく揺れる。これにより、遠心力を作用させた洗濯液が機外に飛散し水漏れが発生したり、洗濯機の振動や騒音が大きくなるというおそれがあった。 The conventional washing machine executes a disturbance step in order to remove the detergent residue 115 that has been adsorbed on the outer surface of the washing / dehydrating tub 103 and the inner surface of the water receiving tub 101 and remains. Therefore, when the laundry 113 in the washing / dehydrating tub 103 is unbalanced, when the control device 116 rotates the washing / dehydrating tub 103, the washing / dehydrating tub 103 violently shakes. As a result, there is a risk that the washing liquid exerted by the centrifugal force may be scattered outside the machine, causing water leakage, and the vibration and noise of the washing machine may increase.

本開示は、撹乱工程における洗濯液の機外への飛び散り、ならびに、洗濯機の振動および騒音を防止する。さらに、洗濯兼脱水槽の外面と水受け槽の内面の壁面に吸着して残っていた洗剤カスを撹乱の水流の力により、安定して除去することを目的としている。 The present disclosure prevents the washing liquid from splashing out of the machine during the disturbance process, as well as vibration and noise of the washing machine. Further, the purpose is to stably remove the detergent residue remaining after being adsorbed on the outer surface of the washing / dehydrating tank and the inner wall surface of the water receiving tank by the force of the disturbing water flow.

本開示に係る洗濯機は、洗濯兼脱水槽と、前記洗濯兼脱水槽を備えた水受け槽と、前記洗濯兼脱水槽を回転駆動する駆動部と、前記洗濯兼脱水槽の水位を検知する水位検知部と、洗い工程、すすぎ工程、および、脱水工程を実行する制御部とを備えている。前記制御部は、前記すすぎ工程において、前記駆動部による前記洗濯兼脱水槽の回転によって、前記水受け槽内の洗濯液に遠心力を作用させ、前記洗濯兼脱水槽と前記水受け槽の間の洗濯液を撹乱する撹乱工程を実行する。前記制御部は、前記撹乱工程において、前記水位検知部の出力に応じて、前記洗濯兼脱水槽の回転数を低減する変更工程の実行を決定する。 The washing machine according to the present disclosure detects the washing / dehydrating tub, the water receiving tub provided with the washing / dehydrating tub, the drive unit for rotating and driving the washing / dehydrating tub, and the water level of the washing / dehydrating tub. It includes a water level detection unit and a control unit that executes a washing process, a rinsing process, and a dehydration process. In the rinsing step, the control unit causes a centrifugal force to act on the washing liquid in the water receiving tub by the rotation of the washing / dehydrating tub by the driving unit, and between the washing / dehydrating tub and the water receiving tub. Perform a perturbation step that perturbs the washing liquor. In the disturbance step, the control unit determines the execution of the changing step of reducing the rotation speed of the washing / dehydrating tub according to the output of the water level detecting unit.

本開示における洗濯機は、撹乱工程における洗濯液の機外への飛び散り、ならびに、洗濯機の振動および騒音を防止する。さらに、洗濯兼脱水槽の外面と水受け槽の内面の壁面に吸着して残っていた洗剤カスを撹乱の水流の力により、安定して除去することができる。 The washing machine in the present disclosure prevents the washing liquid from splashing out of the machine in the disturbing process, and the vibration and noise of the washing machine. Further, the detergent residue remaining adsorbed on the outer surface of the washing / dehydrating tub and the inner surface of the water receiving tub can be stably removed by the force of the disturbing water flow.

The control unit 19 performs a washing step in which the motor 6 is rotationally driven and the washing / dehydrating tub 3 and / or the pulsator 2 is rotated to remove dirt adhering to the laundry 13 (step S1).

つぎに、洗濯物１３に残留付着した洗剤成分を取り除くために、汚れ、洗剤成分を含んだ洗濯液の排水が一度行われる。そして、再び給水が行われて、制御部１９は、洗濯兼脱水槽３および／またはパルセータ２を回転させ、洗濯物１３から洗剤成分を取り除くすすぎ工程を開始する（ステップＳ２）。 Next, in order to remove the detergent component remaining on the laundry 13, the washing liquid containing dirt and the detergent component is drained once. Then, water is supplied again, and the control unit 19 rotates the washing / dehydrating tub 3 and / or the pulsator 2 to start a rinsing step of removing the detergent component from the laundry 13 (step S2).

上述のとおり、制御部１９は、すすぎ工程の終わりに、洗濯液の排水の途中に所定水位で排水を止めるように制御し、再度、洗濯兼脱水槽３が回転するようにモータ６を駆動して（ステップＳ４）、撹乱工程を実行する（ステップＳ３）。これにより、水受け槽１の洗濯液に遠心力が作用し、洗濯液が撹乱する。 As described above, at the end of the rinsing process, the control unit 19 controls so that the drainage is stopped at a predetermined water level during the drainage of the washing liquid, and drives the motor 6 so that the washing / dehydrating tub 3 rotates again. (Step S4), the disturbance step is executed (step S3). As a result, centrifugal force acts on the washing liquid in the water receiving tank 1, and the washing liquid is disturbed.

この洗濯液の撹乱は、洗濯液に遠心力が作用して、洗濯兼脱水槽３と水受け槽１の間を回転するときに、洗濯兼脱水槽３および水受け槽１の僅かな壁面の凹凸によって発生する。 This disturbance of the washing liquid causes a centrifugal force acting on the washing liquid to rotate between the washing / dehydrating tub 3 and the water receiving tub 1, and the slight wall surfaces of the washing / dehydrating tub 3 and the water receiving tub 1 are affected. It is caused by unevenness.

水受け槽１内の水位は、洗濯兼脱水槽３の回転数が高くなるほど、遠心力の作用で上昇する。なお、本実施の形態においては、図４で示すように、水位検知部１８の出力と水受け槽１の水位との関係は、水位が上昇するにつれて、水位検知部１８の出力値は低くなる関係となっている。 The water level in the water receiving tank 1 rises due to the action of centrifugal force as the rotation speed of the washing / dehydrating tank 3 increases. In the present embodiment, as shown in FIG. 4, the relationship between the output of the water level detection unit 18 and the water level of the water receiving tank 1 is that the output value of the water level detection unit 18 decreases as the water level rises. It is a relationship.

また図５に示すように、水位検知部１８の出力と洗濯兼脱水槽３の回転数の関係は、洗濯兼脱水槽３の回転数が高くなるにつれて、水位検知部１８の出力値は低くなる関係となっている。 Further, as shown in FIG. 5, the relationship between the output of the water level detection unit 18 and the rotation speed of the washing / dehydrating tub 3 decreases as the rotation speed of the washing / dehydrating tub 3 increases. It is a relationship.

制御部１９は、撹乱工程（ステップＳ３）が終了すると、すすぎ工程に使われた洗濯液を排水し、洗濯兼脱水槽３が回転して、遠心力によって洗濯物１３に含まれた洗濯液を排出する脱水工程を実行する（ステップＳ７）。脱水工程において、制御部１９はまず排水弁８を開放して排水する。排水が終了すると、制御部１９はクラッチ機構７を脱水側に切り換えて、モータ６の動力を脱水軸を介し洗濯兼脱水槽３に伝達して回転させ、脱水を実行する。排水弁８は開放状態を維持する。脱水工程（ステップＳ７）の終了によって運転終了となる。 When the disturbance step (step S3) is completed, the control unit 19 drains the washing liquid used in the rinsing step, the washing / dehydrating tub 3 rotates, and the washing liquid contained in the laundry 13 is discharged by centrifugal force. A dehydration step of discharging is executed (step S7). In the dehydration step, the control unit 19 first opens the drain valve 8 to drain water. When the drainage is completed, the control unit 19 switches the clutch mechanism 7 to the dehydration side, transmits the power of the motor 6 to the washing / dehydrating tub 3 via the dehydration shaft, rotates it, and executes dehydration. The drain valve 8 maintains an open state. The operation ends when the dehydration step (step S7) is completed.

以上のような一連の動作において、本実施の形態に係る洗濯機においては、撹乱工程（ステップＳ３）において、制御部１９は、水位検知部１８によって測定された水位変動に基づいて、アンバランス検知を実行する（ステップＳ５）。 In the series of operations as described above, in the washing machine according to the present embodiment, in the disturbance step (step S3), the control unit 19 detects the imbalance based on the water level fluctuation measured by the water level detection unit 18. Is executed (step S5).

図５に示すように、洗濯物１３のバランスが良い状態であれば、洗濯兼脱水槽３の回転数が上昇するのにあわせて、水位検知部１８の出力値も連動して変化する。これに対し、洗濯物１３のバランスが悪い状態では、洗濯兼脱水槽３の回転数上昇にあわせて、水受け槽１に激しい揺れが発生するとともに、遠心力を作用させた洗濯液の上下変動が発生するため、水位検知部１８の出力値は大きく変動する。 As shown in FIG. 5, if the laundry 13 is in a well-balanced state, the output value of the water level detection unit 18 changes in conjunction with the increase in the rotation speed of the washing / dehydrating tub 3. On the other hand, when the laundry 13 is in an unbalanced state, the water receiving tub 1 violently shakes as the rotation speed of the washing / dehydrating tub 3 increases, and the washing liquid caused by centrifugal force fluctuates up and down. The output value of the water level detection unit 18 fluctuates greatly.

以下、アンバランス検知の詳細について説明する。モータ６の駆動によって、洗濯兼脱水槽３を回転させる間に、１００ｍｓ毎に水位検知部１８の出力値を記憶する。１秒間の最初の出力値をＨ０とし、最大出力値をＨｍａｘとした場合、設定値以上（例えば、Ｈｍａｘ−Ｈ０＞８００Ｈｚ）であれば、制御部１９は洗濯物１３のアンバランスが発生していると判断し（ステップＳ５のＹｅｓ）、回転数変更工程を実行する（ステップＳ６）。すなわち、制御部１９は、洗濯兼脱水槽３の水位の変動（すなわち、水位検知部１８の出力値の変動）が閾値を超える場合には、洗濯物１３のアンバランスが発生していると判定し、回転数変更工程（ステップＳ６）を実行する。 The details of the imbalance detection will be described below. The output value of the water level detection unit 18 is stored every 100 ms while the washing / dehydrating tub 3 is rotated by the drive of the motor 6. When the initial output value for 1 second is H0 and the maximum output value is Hmax, if it is equal to or higher than the set value (for example, Hmax-H0> 800 Hz), the control unit 19 causes the laundry 13 to be unbalanced. It is determined that there is (Yes in step S5), and the rotation speed changing step is executed (step S6). That is, when the fluctuation of the water level of the washing / dehydrating tub 3 (that is, the fluctuation of the output value of the water level detecting unit 18) exceeds the threshold value, the control unit 19 determines that the laundry 13 is unbalanced. Then, the rotation speed changing step (step S6) is executed.

回転数変更工程（ステップＳ６）においては、洗濯兼脱水槽３の回転数を、例えば目標設定回転数２００ｒｐｍに対し、１５０ｒｐｍにするなど、洗濯兼脱水槽３の回転数が低減される。すなわち、水受け槽１の激しい揺れを低減させた状態にして、モータ６による洗濯兼脱水槽３の回転を継続するようにする。また、水位検知部１８の出力値の変動が閾値以下であれば、制御部１９は、洗濯物１３のアンバランスは発生していないと判断し（ステップＳ５のＮｏ）、回転数変更工程（ステップＳ６）を実行することなく、目標設定回転数にて回転を継続するように制御する。そして、制御部１９は、脱水工程（ステップＳ７）に移行する。 In the rotation speed changing step (step S6), the rotation speed of the washing / dehydrating tub 3 is reduced by, for example, setting the rotation speed of the washing / dehydrating tub 3 to 150 rpm with respect to the target set rotation speed of 200 rpm. That is, the rotation of the washing / dehydrating tub 3 by the motor 6 is continued in a state where the violent shaking of the water receiving tub 1 is reduced. If the fluctuation of the output value of the water level detection unit 18 is equal to or less than the threshold value, the control unit 19 determines that the unbalance of the laundry 13 has not occurred (No in step S5), and changes the rotation speed (step). Control is performed so that the rotation is continued at the target set rotation speed without executing S6). Then, the control unit 19 shifts to the dehydration step (step S7).

これにより、制御部１９はモータ６の回転を制御し、遠心力を作用させた水受け槽１の洗濯液が洗濯兼脱水槽３の上面を超えないように、洗濯兼脱水槽３の回転を制御する。これにより、洗濯液が機外へ飛び散ることが防止され、また洗濯機の振幅を抑制することもできる。したがって、撹乱工程における振動や騒音が防止されるとともに、洗濯兼脱水槽の外面と水受け槽の内面の壁面に吸着して残っていた洗剤カスを撹乱の水流の力により安定して除去することができる。 As a result, the control unit 19 controls the rotation of the motor 6 to rotate the washing / dehydrating tub 3 so that the washing liquid in the water receiving tub 1 on which the centrifugal force is applied does not exceed the upper surface of the washing / dehydrating tub 3. Control. This prevents the washing liquid from splashing out of the machine and also suppresses the amplitude of the washing machine. Therefore, vibration and noise in the disturbing process are prevented, and the detergent residue remaining adsorbed on the outer surface of the washing / dehydrating tank and the inner surface of the water receiving tank is stably removed by the force of the disturbing water flow. Can be done.

以上説明したとおり、本実施形態に係る洗濯機においては、制御部１９は、撹乱工程において、水位検知部１８により検出された洗濯兼脱水槽３の水位変動が閾値を超える場合には、洗濯兼脱水槽３の回転数を低減する変更工程を実行する。 As described above, in the washing machine according to the present embodiment, the control unit 19 also performs washing when the water level fluctuation of the washing / dehydrating tub 3 detected by the water level detecting unit 18 exceeds the threshold value in the disturbance step. A changing step of reducing the number of rotations of the dehydration tank 3 is performed.

The same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

実施の形態２に係る洗濯機においては、図６に示すように、制御部１９がアンバランス異常を検知し洗濯物１３の状態がアンバランスであると判断した場合（ステップＳ１５のＹｅｓ）は、制御部１９は洗濯兼脱水槽３の回転運転を中断する。そして、制御部１９は、給水工程−撹乱工程−排水工程からなる修正すすぎ工程を実行する（ステップＳ１６）。制御部１９は、修正すすぎ工程の後に、再度、洗濯兼脱水槽３が回転するようにモータ６を駆動して（ステップＳ１４）、撹乱工程を実行する（ステップＳ１３）。すなわち、制御部１９は、撹乱工程（ステップＳ１３）のアンバランス検知（ステップＳ１５）において、水位検知部１８により検出された洗濯兼脱水槽３の水位の変動が閾値を超える場合（ステップＳ１５のＹｅｓ）には、修正すすぎ工程を実行する（ステップＳ１６）。 In the washing machine according to the second embodiment, as shown in FIG. 6, when the control unit 19 detects an unbalanced abnormality and determines that the state of the laundry 13 is unbalanced (Yes in step S15), The control unit 19 interrupts the rotary operation of the washing / dehydrating tub 3. Then, the control unit 19 executes a modified rinsing step including a water supply step, a disturbance step, and a drainage step (step S16). After the correction rinsing step, the control unit 19 drives the motor 6 so that the washing / dehydrating tub 3 rotates again (step S14), and executes the disturbance step (step S13). That is, when the fluctuation of the water level of the washing / dehydrating tub 3 detected by the water level detection unit 18 exceeds the threshold value in the imbalance detection (step S15) of the disturbance step (step S13), the control unit 19 is Yes. ), The modified rinsing step is executed (step S16).

これにより、洗濯物１３がアンバランスの状態で洗濯兼脱水槽３の回転数が上昇していく際に発生する水受け槽１の激しい揺れが防止される。また洗濯物１３のアンバランス状態を解消することができるため、洗濯機の振動や騒音を抑え、洗濯兼脱水槽３の外面と水受け槽１の内面の壁面に吸着して残っていた洗剤カスを撹乱の水流の力により安定して除去することができる。 As a result, the violent shaking of the water receiving tub 1 that occurs when the rotation speed of the washing / dehydrating tub 3 increases while the laundry 13 is unbalanced is prevented. Further, since the unbalanced state of the laundry 13 can be eliminated, the vibration and noise of the washing machine are suppressed, and the detergent residue remaining after being adsorbed on the outer surface of the washing / dehydrating tub 3 and the inner wall surface of the water receiving tub 1 is suppressed. Can be stably removed by the force of the disturbing water flow.

本実施の形態に係る洗濯機においては、図７に示すように、洗濯兼脱水槽３と水受け槽１の間の洗濯液を撹乱する工程において、洗濯兼脱水槽３の回転前から排水弁８を開放して洗濯液の排水を始め、洗濯兼脱水槽３を回転しながら排水する。すなわち、制御部１９は、洗濯兼脱水槽３の回転数を上昇させながら、洗濯液の排水を実行する。これにより、
撹乱の力により、洗剤カスを除去しながら洗濯液が排水されるので、洗濯時間を短くできる。さらに除去された洗剤カスが洗濯兼脱水槽３に浸入し、洗濯物１３に洗剤カスが再付着することを防止することができる。 In the washing machine according to the present embodiment, as shown in FIG. 7, in the step of disturbing the washing liquid between the washing / dehydrating tub 3 and the water receiving tub 1, the drain valve is started before the washing / dehydrating tub 3 rotates. 8 is opened to start draining the washing liquid, and the washing / dehydrating tub 3 is rotated to drain the washing liquid. That is, the control unit 19 drains the washing liquid while increasing the rotation speed of the washing / dehydrating tub 3. This will

Prevents the washing liquid from splashing out of the machine during the disturbance process, as well as vibration and noise of the washing machine. In addition, the detergent residue remaining adsorbed on the outer surface of the washing / dehydrating tub and the inner surface of the water receiving tub can be stably removed by the force of the disturbing water flow. Therefore, it is useful as a washing machine or the like that prevents the detergent residue from reattaching to the laundry, keeps the clothes clean, and improves the safety.
