Description

本発明は、ドラム内部に回転部材を備えた、ドラム式洗濯機に関するものである。   The present invention relates to a drum type washing machine provided with a rotating member inside a drum.

図９に示すとおり、ドラム式洗濯機の脱水工程では、洗濯物が偏り、ドラム内周面でアンバランス状態のまま脱水回転を高速にすると、製品の振動、及び、騒音が大きくなるため、脱水起動時にドラム回転が低速定常回転時に洗濯物がドラムの内周面上に張り付いた状態でアンバランス量の検出を行い、洗濯物が均等に分散し、アンバランス量が小さければ、ドラム回転を増速し、段階的に最終の回転速度までこの検出を数回繰り返すことで、できる限り製品の振動を抑えていた。また、洗濯物の分散が上手くいかずにアンバランス量が大きいと検知すれば、図１０に示すとおり一度ドラムを静止し、ドラムを正転逆転することなどで洗濯物をほぐし、再度低速の回転速度から再始動していた。
特開昭６２−８７１９１号公報 As shown in FIG. 9, in the dewatering process of the drum type washing machine, if the laundry is biased and the dewatering rotation is performed at high speed while the drum inner peripheral surface is in an unbalanced state, the vibration and noise of the product increase. Drum rotation at start-up and low-speed steady rotation, the laundry is stuck on the drum's inner surface and the unbalance amount is detected.If the laundry is evenly distributed and the unbalance amount is small, the drum rotation By increasing the speed and repeating this detection several times to the final rotational speed step by step, the vibration of the product was suppressed as much as possible. In addition, if it is detected that the laundry is not well dispersed and the unbalance amount is large, as shown in FIG. 10, the drum is stopped once, and the drum is rotated forward and reverse to loosen the laundry, and then rotate at a low speed again. It was restarting from speed.
JP-A-62-87191

しかしながら、振動と騒音の低減をするために、洗濯物がドラム内周面に一度張り付くと移動することができず、アンバランス量が大きいと検知すればドラム回転を静止させる必要があり、静止後再度同じ動作が必要となるため、脱水起動中のアンバランス量が大きい時にはかなりの脱水時間を要していた。   However, in order to reduce vibration and noise, once the laundry has stuck to the drum inner peripheral surface, it cannot move, and if it detects that the amount of unbalance is large, it is necessary to stop the drum rotation. Since the same operation is required again, a considerable amount of dehydration time was required when the amount of unbalance during dehydration activation was large.

前記従来の課題を解決するために、本発明のドラム式洗濯機は、外槽内に回転自在のドラムと、前記ドラム内に回転自在である回転部材と、前記ドラムと前記回転部材とが同方向に異なる速度で回転する相対回転と同方向に同一速度で回転する同一回転とをさせる駆動装置と、前記駆動装置の駆動を制御する制御手段と、洗濯物の偏りによるアンバランス量を検知する検知手段とを備え、脱水工程中の脱水起動時に前記ドラムを所定の速度で回転させながら、前記ドラムと前記回転部材とを相対回転させるようにしたものである。   In order to solve the conventional problems, a drum-type washing machine of the present invention includes a drum that is rotatable in an outer tub, a rotating member that is rotatable in the drum, and the drum and the rotating member that are the same. A driving device that performs a relative rotation that rotates at different speeds in the direction and a same rotation that rotates at the same speed in the same direction, a control unit that controls driving of the driving device, and an unbalance amount due to the bias of the laundry Detecting means, and rotating the drum relative to the rotating member while rotating the drum at a predetermined speed when dehydration is started during the dehydration process.

これによって、脱水起動時に洗濯物の偏りによるアンバランス量が大きいと検知した場合であっても、ドラムと回転部材を静止させることなく洗濯物の位置を修正し、継続的に回転させることができる。   Thus, even when it is detected that the unbalance amount due to the bias of the laundry is large at the time of dehydration activation, the position of the laundry can be corrected without causing the drum and the rotating member to stand still and can be continuously rotated. .

本発明のドラム式洗濯機は、脱水工程中の脱水起動時に、洗濯物の分散を程よくし、ドラムと回転部材の回転を静止させることなく、洗濯物の偏りによるアンバランス量を低減できるため、脱水起動中のアンバランス量が大きい時であっても脱水時間を短縮するができる。   The drum type washing machine of the present invention can moderately disperse the laundry at the start of dehydration during the dehydration process, and can reduce the unbalance amount due to the bias of the laundry without stopping the rotation of the drum and the rotating member. Even when the amount of unbalance during dehydration is large, the dehydration time can be shortened.

By doing so, the laundry moves while maintaining the state of sticking to the inner peripheral surface of the drum, and the position of the laundry can be corrected evenly while the rotational speed of the drum is increased.

第４の発明は、ドラムと回転部材が相対回転した後に同一回転させることで、洗濯物に作用する遠心力より、洗濯物に作用する重力の方が大きくなる回転速度でドラムを回転させ同一回転させることにより、洗濯物をドラムと同一回転させることとなり、ドラム内の洗濯物の偏りによるアンバランス量を正確に検知することができる。   According to a fourth aspect of the present invention, the drum and the rotating member rotate relative to each other and rotate the same to rotate the drum at a rotation speed at which the gravity acting on the laundry becomes larger than the centrifugal force acting on the laundry. By doing so, the laundry is rotated in the same direction as the drum, and the unbalance amount due to the bias of the laundry in the drum can be accurately detected.

第５の発明は、洗濯物の偏りによるアンバランス量を検知する検知手段を備え、相対回転時に検知したアンバランス量が所定量よりも大きいと、ドラムが回転することで洗濯物に作用する遠心力よりも洗濯物に作用する重力の方が大きくなる回転速度でドラムを回転させ、回転部材をドラムと同方向にドラムより速い回転速度で回転させて、洗濯物の位置が均等になるように修正することにより、ドラムを継続的に回転させることになり、脱水を停止することなく脱水を再度立上げる時間を短縮することができる。   5th invention is equipped with the detection means which detects the unbalance amount by the bias | inclination of the laundry, and when the unbalance amount detected at the time of relative rotation is larger than predetermined amount, the centrifugal force which acts on laundry by rotating a drum Rotate the drum at a rotational speed at which the gravity acting on the laundry is greater than the force, and rotate the rotating member in the same direction as the drum at a rotational speed faster than the drum so that the position of the laundry is even By correcting, the drum is continuously rotated, and the time for starting up the dehydration again can be shortened without stopping the dehydration.

Therefore, it is possible to determine the bias of the laundry.

After that, the water in the outer tub 1 is drained to the outside by opening the drainage device 22, the laundry 5 is loosened by rotating the drum 4 and the rotating member 15, and then rotated with the drum 4 in the outer tub 1. The member 15 is rotated in the same direction and at the same speed, but before the drum 4 and the rotating member 15 are rotated at the same speed in the dehydration process in which water is discharged from the laundry 5 through the drum hole 8 by rotating at a high speed. In addition, there are a plurality of modes depending on the combination of the respective rotational speeds of the drum 4 and the rotating member 15 during the dehydration start up from the unbalance amount to the high speed rotation by the detecting means 26 for detecting the unbalance amount. It will be described below.

モード１：ドラム４のみが回転することで洗濯物５に作用する遠心力より、洗濯物５に
作用する重力の方が大きくなる回転速度でドラム４を一定方向に一定回転させ、回転部材１５をドラム４と同一方向にドラム４より速い回転速度で一定方向に一定回転させることで、洗濯物５が回転部材１５の回転に引っ張られ、ドラムの内周面上に沿うように移動させるモードである。 Mode 1: When only the drum 4 rotates, the drum 4 is rotated in a certain direction at a rotation speed at which the gravity acting on the laundry 5 becomes larger than the centrifugal force acting on the laundry 5, and the rotating member 15 is rotated. In this mode, the laundry 5 is pulled by the rotation of the rotating member 15 and moved along the inner peripheral surface of the drum by rotating it in a certain direction at a higher rotational speed than the drum 4 in the same direction as the drum 4. .

モード２：ドラム４のみが回転することで洗濯物５に作用する遠心力より、洗濯物５に作用する重力の方が小さくなる回転速度でドラム４を一定方向に一定回転させ、回転部材１５をドラム４と同一方向にドラム４より速い回転速度で一定方向に一定回転させることで、洗濯物５がドラム内周面７に張り付いた状態で、洗濯物５の位置を変えるモード。   Mode 2: When only the drum 4 rotates, the drum 4 is rotated in a certain direction at a rotational speed at which the gravity acting on the laundry 5 becomes smaller than the centrifugal force acting on the laundry 5, and the rotating member 15 is rotated. A mode in which the position of the laundry 5 is changed in a state in which the laundry 5 is stuck to the drum inner peripheral surface 7 by rotating it in a constant direction at a higher rotational speed than the drum 4 in the same direction as the drum 4.

モード３：ドラム４と回転部材５が同一方向に異なる速度で回転した後に、ドラム４のみが回転することで洗濯物５に作用する遠心力より、洗濯物５に作用する重力の方が小さくなる回転速度で同一方向に、同一速度で回転することで、洗濯物５の位置を一定に保つモード。   Mode 3: After the drum 4 and the rotating member 5 rotate at different speeds in the same direction, the gravity acting on the laundry 5 becomes smaller than the centrifugal force acting on the laundry 5 by rotating only the drum 4. A mode in which the position of the laundry 5 is kept constant by rotating at the same speed in the same direction at the rotational speed.

図３、５、６、７において、脱水起動中にモード１、２、３を用いた動作方法を以下に説明する。   3, 5, 6, and 7, an operation method using modes 1, 2, and 3 during dehydration activation will be described below.

ドラム４及び回転部材１５５を回転させ洗濯物５を洗い、すすいだ後に、外槽１内の水を排水装置２２を開くことで外部に排水し、洗濯物５をドラム４及び回転部材１５を回転させることでほぐした後に、モード１を実行し、モード１間でアンバランス量を検知し続ける。   The drum 4 and the rotating member 155 are rotated to wash and wash the laundry 5, and then the water in the outer tub 1 is drained to the outside by opening the drainage device 22, and the laundry 5 is rotated to the drum 4 and the rotating member 15. After loosening, mode 1 is executed and the unbalance amount is continuously detected between modes 1.

ここで、ドラム４の回転速度は４５ｒｐｍ、回転部材１５の回転速度は９０ｒｐｍとしているが、ドラム４のみが回転することで洗濯物５に作用する遠心力より、洗濯物５に作用する重力の方が大きくなる回転速度でドラム４を回転できる速度であればよい。また、回転部材１５をドラム４と同一方向にドラム４より速い回転速度であればよい。   Here, the rotational speed of the drum 4 is 45 rpm, and the rotational speed of the rotating member 15 is 90 rpm. However, the gravity acting on the laundry 5 is more effective than the centrifugal force acting on the laundry 5 when only the drum 4 rotates. Any speed may be used as long as the drum 4 can be rotated at a rotational speed at which the speed increases. Further, the rotational speed of the rotating member 15 may be higher than that of the drum 4 in the same direction as the drum 4.

アンバランス量が所定量よりも大きければモード１を繰り返すが、所定量より小さければ回転部材１５の回転速度にドラム４の回転速度を同一にするモード３に移行する。   If the unbalance amount is larger than the predetermined amount, mode 1 is repeated. If the unbalance amount is smaller than the predetermined amount, the mode shifts to mode 3 in which the rotational speed of the drum 4 is made equal to the rotational speed of the rotating member 15.

モード３間では、洗濯物５が張り付いた状態となり、アンバランス量を正確に検知することができる。   Between modes 3, the laundry 5 is stuck, and the amount of imbalance can be accurately detected.

モード３において、アンバランス量が所定量より小さければ、同一回転の状態で両方の回転速度を上げ、所定量より大きければ図３と図６のとおりモード２に移行し、回転部材１５のみ回転速度を増速して一定回転させ、洗濯物５の位置を変えることでアンバランス量を所定量以下にする。   In mode 3, if the unbalance amount is smaller than the predetermined amount, both rotational speeds are increased in the same rotation state, and if larger than the predetermined amount, the mode shifts to mode 2 as shown in FIG. 3 and FIG. The unbalance amount is set to a predetermined amount or less by changing the position of the laundry 5 by increasing the speed of the laundry 5 and rotating the laundry 5 at a constant speed.

モード２間でアンバランス量を検知し続け、所定量より小さければ回転部材１５をドラム４の回転速度まで減速しドラム４と同一回転させる。所定量より大きければモード１に移行し、ドラム４と回転部材１５を静止させずにモード１から繰り返す。   The unbalance amount is continuously detected between modes 2, and if it is smaller than the predetermined amount, the rotating member 15 is decelerated to the rotational speed of the drum 4 and is rotated in the same direction as the drum 4. If it is larger than the predetermined amount, the mode is shifted to the mode 1, and the drum 4 and the rotating member 15 are repeated from the mode 1 without being stationary.

モード３でアンバランス量が所定量より小さい時に、両回転速度を所定の回転速度まで上げ一定速度に保ち、アンバランス量の検知をし、この段階で所定量より大きい場合にはモード２に移行して洗濯物５の位置を修正し、段階的に繰返し、ドラム４と回転部材１５を静止させることなく高速回転まで増速させる。   When the unbalance amount is smaller than the predetermined amount in mode 3, both rotational speeds are increased to the predetermined rotational speed and kept at a constant speed, and the unbalance amount is detected. Then, the position of the laundry 5 is corrected and repeated stepwise, and the drum 4 and the rotating member 15 are increased to a high speed rotation without being stationary.

以上のように、洗濯物５の偏りによるアンバランス量を検知し、ドラム４と回転部材１５を静止させることなく高速回転まで増速させることで、脱水起動の時間を短縮すること
ができる。また、脱水工程が複数回行われる時には洗濯時間全体を短縮することができる。 As described above, by detecting the unbalance amount due to the bias of the laundry 5 and increasing the speed of the drum 4 and the rotating member 15 to high speed rotation without being stationary, the dehydration activation time can be shortened. Further, when the dehydration process is performed a plurality of times, the entire washing time can be shortened.

また、本実施の形態をドラム式洗濯機としているが、洗濯と乾燥機能を備えたドラム式洗濯乾燥機においても同様の効果を奏することができる。   Further, although the present embodiment is a drum type washing machine, a drum type washing and drying machine having a washing and drying function can achieve the same effect.

また、本実施の形態ではドラムの回転軸を水平に対して傾斜角を有するドラム式洗濯機としているが、ドラムの回転軸を水平軸にて構成されたドラム式洗濯機においても、同様の効果を奏することができる。   In the present embodiment, the drum rotation shaft is a drum type washing machine having an inclination angle with respect to the horizontal.

1 and 2 are sectional views of a drum-type washing machine according to the second embodiment of the present invention, and a description of the same configuration as that of the first embodiment will be omitted. FIG. 4 is a control flow diagram for detecting imbalance and driving patterns of the drum and the rotating member in the second embodiment of the present invention, and FIG. 8 is a sequence diagram of the drum and rotating member in the second embodiment of the present invention. Is shown.

図４、８において、脱水起動中にはドラム４と回転部材１５の各回転速度の組合せによる本発明の実施の形態２のモード１とモード３があり、以下に動作方法を説明する。   4 and 8, there are modes 1 and 3 according to the second embodiment of the present invention in which the rotation speeds of the drum 4 and the rotating member 15 are combined during dehydration activation, and the operation method will be described below.

まずモード１を実行し、所定時間後にモード３に移行する。   First, mode 1 is executed, and mode 3 is entered after a predetermined time.

モード３間でアンバランス量を検知し、所定量よりも大きければ、モード１に移行し洗濯物５を再配置したうえで再度モード３に移行する。また、アンバランス量が所定量より小さければ、両回転速度を所定の回転速度まで増速して一定速度を保ち、アンバランス量の検知をすることを段階的に繰返し、ドラム４と回転部材１５を静止させることなく高速回転まで増速させる。   If the amount of imbalance is detected between the modes 3, and if it is larger than the predetermined amount, the mode is shifted to the mode 1, the laundry 5 is rearranged, and the mode 3 is shifted again. If the unbalance amount is smaller than the predetermined amount, the both rotational speeds are increased to the predetermined rotational speed to maintain a constant speed, and the detection of the unbalance amount is repeated step by step. Speed up to high speed without stopping.

以上のように、洗濯物５の偏りによるアンバランス量を検知し、ドラム４と回転部材１５を静止させることなく高速回転まで増速させることで、脱水起動の時間を短縮することができる。また、脱水工程が複数回行われる時には洗濯時間全体を短縮することができる。   As described above, by detecting the unbalance amount due to the bias of the laundry 5 and increasing the speed of the drum 4 and the rotating member 15 to high speed rotation without being stationary, the dehydration activation time can be shortened. Further, when the dehydration process is performed a plurality of times, the entire washing time can be shortened.

また、本実施の形態をドラム式洗濯機としているが、洗濯と乾燥機能を備えたドラム式洗濯乾燥機においても同様の効果を奏することができる。   Further, although the present embodiment is a drum type washing machine, a drum type washing and drying machine having a washing and drying function can achieve the same effect.

以上のように、本発明のドラム式洗濯機は、脱水起動中に洗濯物の偏りにより発生するアンバランスをドラムと回転部材を静止させることなく、アンバランスを減少し、脱水を進めることができ、再立上の時間を短縮するのに有用である。   As described above, the drum-type washing machine according to the present invention can reduce the unbalance caused by the bias of the laundry during the start of the dehydration without stopping the drum and the rotating member, and can proceed with the dehydration. Useful to shorten the time for re-rise.
