Description
本発明は、洗濯機に関するものである。 The present invention relates to a washing machine.
洗濯機，例えばドラム式洗濯乾燥機では、洗濯兼脱水槽であるドラム内の衣類分布に偏りが生じていると、この偏りが加振力となりドラムが回転する際に振動が発生する。この振動は、ドラム、外槽、モータなどの部品から成る振動部によるものであり，振動部から筺体，筺体から床へと伝達する。洗濯機が脱水運転を行っている際の振動で課題となるものは，外槽の振動，筺体の振動，洗濯機が設置されている床の振動，そして洗濯機が設置されている家の各部の振動がある。外槽や筺体，床などはそれぞれが共振する共振周波数が存在する。共振周波数で加振されると，他の周波数で加振される場合に比べて振動が大きくなる。従って，振動させたくない物の共振周波数を避けて洗濯機を運転する事が重要となる。すなわち，外槽，筺体，床などの共振周波数となるドラムの回転速度を避けた運転を行う。 In a washing machine, for example, a drum-type washing / drying machine, if there is a bias in the distribution of clothes in the drum, which is a washing and dewatering tub, this bias becomes an excitation force and vibration is generated when the drum rotates. This vibration is caused by a vibration part including parts such as a drum, an outer tub, and a motor, and is transmitted from the vibration part to the casing and from the casing to the floor. The problems that occur when the washing machine performs dehydration operations are the vibration of the outer tub, the vibration of the enclosure, the vibration of the floor where the washing machine is installed, and the parts of the house where the washing machine is installed. There is a vibration. The outer tank, the housing, the floor, etc. have resonance frequencies at which they resonate. When the vibration is applied at the resonance frequency, the vibration is larger than when the vibration is applied at the other frequency. Therefore, it is important to operate the washing machine while avoiding the resonance frequency of things that you do not want to vibrate. That is, the operation is performed while avoiding the rotation speed of the drum, which has a resonance frequency such as the outer tank, the casing, and the floor.
しかし，一般的に脱水回転速度よりも外槽や筺体が共振する回転速度（以下，共振回転速度）が小さいため，脱水回転速度に加速する間に外槽や筺体の共振回転速度を通過することになる。そこで，外槽や筺体の共振回転速度で回転する時間を短縮することで振動を低減する方法が提案されている。外槽の共振回転速度はこの外槽の防振支持機構の影響を受けるため，製造段階で外槽の共振回転速度で回転する時間を短くするように制御するソフトを作成することは可能である。一方，筺体の共振回転速度は設置される床の影響を受け，床が柔らかい程低くなる傾向がある。しかし、製造段階においては、当然ながら、洗濯機がどこに設置されるかを把握できない。 However, since the rotation speed at which the outer tub and the enclosure resonate is generally smaller than the dehydration rotation speed (hereinafter referred to as the resonance rotation speed), the resonance rotation speed of the outer tub and the enclosure must pass while accelerating to the dehydration rotation speed. become. In view of this, a method has been proposed in which the vibration is reduced by shortening the time required for rotation at the resonant rotation speed of the outer tub or the casing. Since the outer tank's resonant rotation speed is affected by the outer tank's anti-vibration support mechanism, it is possible to create software that controls to shorten the rotation time at the outer tank's resonant rotation speed during the manufacturing stage. . On the other hand, the resonant rotation speed of the frame is affected by the floor where it is installed, and tends to be lower as the floor is softer. However, in the manufacturing stage, of course, it is impossible to grasp where the washing machine is installed.
そこで，特許文献１に記載の洗濯機では，筐体の振動を検出する検出手段の出力に基づいて筐体の共振回転速度を測定し、この測定結果に基づいて駆動手段を制御する方法が提案されている。 Therefore, in the washing machine described in Patent Document 1, a method is proposed in which the resonance rotational speed of the casing is measured based on the output of the detection means for detecting the vibration of the casing, and the driving means is controlled based on the measurement result. Has been.
また，特許文献２に記載の洗濯機では，本体の設置条件を入力する設置条件入力手段を備え，脱水工程時に，回転ドラムをその内周壁に洗濯物が張り付き易い第１の所定の回転速度まで立ち上げ，内周壁に洗濯物が均等に張り付いているか否かの布バランス判定を実行し，布バランス判定でバランス良好でないと判定された時は布バランス判定動作を繰り返し，良好と判定されたときは回転ドラムを脱水回転速度で運転し，バランス判定を行う際の判定値を設置条件に応じて変更している。例えば，木造住宅等振動の影響を受け易い所に設置された場合に不要に振動が大きくなって脱水運転が中断するのを抑制したり，鉄筋コンクリート住宅のように振動の影響を受けにくい所に設置された場合に布バランス判定を繰り返して全体時間が長くなるのを抑制したりしている。 In addition, the washing machine described in Patent Document 2 includes installation condition input means for inputting the installation conditions of the main body, and at the time of the dehydration process, the rotating drum is brought up to a first predetermined rotation speed at which the laundry easily sticks to the inner peripheral wall. The cloth balance judgment was performed to determine whether the laundry was evenly attached to the inner peripheral wall. When the cloth balance judgment determined that the balance was not good, the cloth balance judgment operation was repeated and the cloth was judged good. In some cases, the rotating drum is operated at the dehydrating rotation speed, and the determination value when performing the balance determination is changed according to the installation conditions. For example, when installed in a place that is susceptible to vibration, such as a wooden house, the vibration is unnecessarily increased, preventing the dehydration operation from being interrupted, or installed in a place that is not susceptible to vibration, such as a reinforced concrete house. In such a case, the cloth balance determination is repeated to prevent the overall time from becoming long.
上記特許文献１のように，筺体にセンサを設置することで，洗濯機が設置されている場所の振動は測定できるが，洗濯機が設置されている場所以外の部分で共振が発生した場合には，その振動を検出することができない。すなわち，床の硬さに依存する筺体の共振回転速度は把握できるが、家の各部の共振回転速度は把握する事が出来ない。 As in the above-mentioned Patent Document 1, by installing a sensor on the housing, the vibration of the place where the washing machine is installed can be measured, but when resonance occurs in a part other than the place where the washing machine is installed Cannot detect that vibration. In other words, the resonance rotation speed of the frame depending on the hardness of the floor can be grasped, but the resonance rotation speed of each part of the house cannot be grasped.
また，上記特許文献２についても，洗濯機が設置されている場所以外の部分の共振回転速度を判断しないため，その共振回転速度でドラムが回転する時間を短縮する事は難しい。さらに，この特許文献２には，柔らかい床ほど脱水回転速度を低下して振動を抑え，低い回転速度でも脱水が完了するように時間を延長することも記載されているが，設置した床が柔らかいと，硬い床に設置した場合に比べて，運転が終了するまでの時間が長くなってしまう。 Also in Patent Document 2, since the resonance rotational speed of the portion other than the place where the washing machine is installed is not judged, it is difficult to shorten the time for the drum to rotate at the resonance rotational speed. Furthermore, this Patent Document 2 also describes that the softer floor lowers the dehydration rotation speed to suppress vibrations, and extends the time so that dehydration is completed even at a lower rotation speed, but the installed floor is softer. Compared to the installation on a hard floor, it takes longer to complete the operation.
本発明は、上記従来の課題を解決するもので，洗濯機の振動が建物に伝わり，洗濯機を設置している床以外の床などで共振が発生する可能性があるような場合でも，快適な運転を行える洗濯機を提供することを目的とする。 The present invention solves the above-mentioned conventional problems, and is comfortable even when the vibration of the washing machine is transmitted to the building and resonance may occur on a floor other than the floor where the washing machine is installed. An object is to provide a washing machine that can be operated smoothly.
このような従来の課題を解決するために，本発明は，衣類を収容する洗濯兼脱水槽と、該洗濯兼脱水槽を内包する外槽と、該外槽を収容する筺体と、前記洗濯兼脱水槽を回転駆動する駆動機構と、該駆動機構を制御する制御手段を備えた洗濯機において、運転中に振動が大きいと感じたときに使用者が操作する入力手段を有し、前記制御手段は、前記入力手段が操作された場合、運転パターンを変更することを特徴とする洗濯機。 In order to solve such a conventional problem, the present invention provides a washing / dehydrating tub for storing clothes, an outer tub containing the washing / dehydrating tub, a housing for storing the outer tub, and the washing / dehydrating tub. A washing machine having a drive mechanism for rotationally driving a dewatering tub and a control means for controlling the drive mechanism, and having an input means for a user to operate when vibration is felt during operation, the control means The washing machine is characterized in that the operation pattern is changed when the input means is operated.
本発明によれば、洗濯機が設置されている床以外の部分が共振する可能性があるような場合でも，快適な運転を行える洗濯機を提供することが可能となる。 ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the washing machine which can perform a comfortable driving | operation even when parts other than the floor in which the washing machine is installed may resonate.

The control pattern determination unit 50 selects an optimum activation pattern from the activation pattern database 44 based on the rotation speed recorded in the rotation speed recording unit 49.
図６から図７を用いて脱水時の振動について詳しく説明する。床の振動はドラムの回転速度の上昇に伴い増加し，床が共振する回転速度で最大となり，さらに回転速度を上昇させると徐々に減少する。従来，脱水は７００ｒ／ｍｉｎ以上で行うことが多く，脱水を行う回転速度以下の回転速度で床の共振が発生する場合がある。共振していると振動が大きくなるため，その回転速度で長時間運転を行うことは使用者が不快に感じる原因となる。一般的にこのように共振が発生する場合には，共振回転速度での運転時間を極力短くする。この方法は床の共振回転速度が分かっている状態であれば非常に有効な手段である。 The vibration during dehydration will be described in detail with reference to FIGS. The vibration of the floor increases as the drum rotation speed increases, reaches the maximum at the rotation speed at which the floor resonates, and gradually decreases as the rotation speed is increased. Conventionally, dehydration is often performed at 700 r / min or more, and floor resonance may occur at a rotational speed lower than the rotational speed at which dehydration is performed. Since vibration increases when resonating, long-time operation at the rotational speed causes the user to feel uncomfortable. Generally, when resonance occurs in this way, the operation time at the resonance rotational speed is shortened as much as possible. This method is very effective as long as the resonance rotational speed of the floor is known.
しかし，床が共振する回転速度は床の硬さによって変化し，床が硬いほど高くなる。床の硬さは家の構造や階層などによって変わるため，製造段階で洗濯機が設置される床の共振回転速度を把握し，前記駆動機構を適切に制御することは困難である。 However, the rotational speed at which the floor resonates varies with the hardness of the floor, and increases as the floor becomes harder. Since the hardness of the floor varies depending on the structure and level of the house, it is difficult to grasp the resonance rotational speed of the floor on which the washing machine is installed in the manufacturing stage and appropriately control the drive mechanism.
図６に４７０ｒ／ｍｉｎと７００ｒ／ｍｉｎに一定時間を持つ起動パターンを一例として示す。ここで，回転速度を上昇する過程で所定の回転速度（以下，保持回転速度）で一定時間を保持するのは，なるべく低い回転速度で衣類を脱水してドラム内の質量を小さくしてから，回転速度を上昇させるためである。また，硬さの異なる床に設置した場合を例として，それぞれの床の共振回転速度は，床（１）：４８０ｒ／ｍｉｎ，床（２）：５８０ｒ／ｍｉｎ，床（３）：６８０ｒ／ｍｉｎとした。 FIG. 6 shows an example of a startup pattern having a fixed time at 470 r / min and 700 r / min. Here, in the process of increasing the rotational speed, maintaining a predetermined time at a predetermined rotational speed (hereinafter referred to as holding rotational speed) is to dehydrate clothing at a rotational speed as low as possible to reduce the mass in the drum, This is to increase the rotation speed. Further, taking the case of installation on floors having different hardness as an example, the resonance rotational speed of each floor is as follows: floor (1): 480 r / min, floor (2): 580 r / min, floor (3): 680 r / min. It was.
図６（ａ）では床の共振回転速度と保持回転速度である４７０ｒ／ｍｉｎが近いために，長時間振動の大きい状態が続いている。一方，保持回転速度を７００ｒ／ｍｉｎで一定時間保持している際は床の共振回転速度と離れているため，振動が小さい状態であり問題はない。図６（ｂ）では床の共振回転速度が保持回転速度から離れているため，長時間大きな振動が続くことはない。図６（ｃ）では床の共振回転速度が７００ｒ／ｍｉｎの保持回転速度と近いため，振動は大きい状態が一定時間継続する。以上のように，床の硬さを考慮しない場合，設置状態によって床の振動が大きい状態で一定時間運転することになるため，使用者の不快感につながる。 In FIG. 6A, since the resonance rotational speed of the floor is close to the holding rotational speed of 470 r / min, the vibration continues for a long time. On the other hand, when the holding rotation speed is held at 700 r / min for a certain period of time, there is no problem because the vibration is small because it is away from the resonance rotation speed of the floor. In FIG. 6 (b), since the resonance rotational speed of the floor is away from the holding rotational speed, large vibration does not continue for a long time. In FIG. 6 (c), since the resonance rotational speed of the floor is close to the holding rotational speed of 700 r / min, the state of large vibration continues for a certain time. As described above, when the floor hardness is not taken into account, the operation is performed for a certain period of time with a large floor vibration depending on the installation state, which leads to user discomfort.
そこで，使用者が床の振動を大きいと判断した場合に，固有値入力手段５を使って床の振動が大きいことを洗濯機１００に入力する。これにより，制御装置７は固有値入力手段５からの信号が入った際のドラム８の回転速度を記録し，その回転速度で回転する時間を短縮するように制御を行う。例えば，固有値入力手段５が押下された時の回転速度に対して，少なくとも±１００ｒ／ｍｉｎ以内に保持回転速度を設けず，さらにその回転速度領域におけるドラム８の回転速度の上昇率を高く設定する。前述したように，製造段階で設定した起動パターンでは，図６（ｃ）のように硬い床に設置した場合，共振回転速度と保持回転速度が近い値となり，振動が大きい状態で回転する時間が長くなる場合がある。しかし，前記のような制御を行うことで，図７に示すようなドラム８の起動パターンを変更する事により，使用者が不快と判断する状態で運転する時間を短縮する事が可能になる。このように共振回転速度を把握する事によって，床が柔らかい場合でも，振動を小さく抑えながら，なるべく高い回転速度で衣類の脱水を行う事ができる。従って，運転時間を延長することなく，衣類の水分量を極力低減できるため，洗濯時には衣類を干す時間の延長を防止する。又，洗濯乾燥機における衣類の水分量を極力減らして乾燥運転を行えるので，衣類の乾燥に必要な消費電力量が増加するのを防止する事が出来る。 Therefore, when the user determines that the floor vibration is large, the eigenvalue input means 5 is used to input to the washing machine 100 that the floor vibration is large. As a result, the control device 7 records the rotational speed of the drum 8 when the signal from the eigenvalue input means 5 is input, and performs control so as to shorten the time for rotation at the rotational speed. For example, the holding rotational speed is not provided within ± 100 r / min with respect to the rotational speed when the eigenvalue input means 5 is pressed, and the rate of increase of the rotational speed of the drum 8 in the rotational speed region is set high. . As described above, in the startup pattern set at the manufacturing stage, when installed on a hard floor as shown in FIG. 6 (c), the resonance rotation speed and the holding rotation speed are close to each other, and the time for rotation with a large vibration is obtained. May be longer. However, by performing the control as described above, it is possible to shorten the operation time in a state where the user judges that the user is uncomfortable by changing the starting pattern of the drum 8 as shown in FIG. By grasping the resonance rotational speed in this way, even when the floor is soft, clothes can be dehydrated at a rotational speed as high as possible while suppressing vibrations to a minimum. Therefore, since the moisture content of the clothes can be reduced as much as possible without extending the operation time, it is possible to prevent an extension of the time for drying the clothes during washing. Moreover, since the moisture content of the clothes in the washing / drying machine can be reduced as much as possible and the drying operation can be performed, it is possible to prevent an increase in power consumption necessary for drying the clothes.
このように，使用者が入力手段により任意に情報を入力することができるため，洗濯機が設置されている床以外においても，所定の部屋の床のみ共振する場合や，部屋に設置された水槽などが共振する場合でも，保持回転速度と共振回転速度をずらした運転をすることが可能となり，低振動な運転を実現する事ができる。 In this way, since the user can input information arbitrarily using the input means, even if the floor of the predetermined room resonates other than the floor where the washing machine is installed, or the water tank installed in the room Even in the case of resonance, it is possible to operate with the holding rotational speed and resonant rotational speed shifted, and to realize low vibration operation.
図８に本実施形態の制御を示すフローチャートを示す。脱水運転を開始し，まず回転速度記録部４９に記録されている共振回転速度ωsを参照する（Ｓｔｅｐ１０１）。ここで，共振回転速度ωsは，以前の運転において固有値入力手段５が押下された時のドラムの回転速度であり，一度も固有値入力手段５が押下されていない場合には初期値が記録されている。Ｓｔｅｐ１０２で共振回転速度ωsを元にドラム８の起動パターンを選択する。決定した起動パターンに従い，Ｓｔｅｐ１０３でドラム８の回転速度を上昇させる。Ｓｔｅｐ１０４で振動センサ１０ｅによって測定した振動量と予め設定されている判定値を比較し，振動量が小さい場合は，Ｓｔｅｐ１０５に進み，振動量が大きい場合はドラム８の回転を停止し，再起動を行う。Ｓｔｅｐ１０５で固有値入力手段５が押下されない場合には，Ｓｔｅｐ１０８に進む。Ｓｔｅｐ１０５で固有値入力手段５が押下された場合には，その時の回転速度ωを共振回転速度ωsとして記録する（Ｓｔｅｐ１０６）。Ｓｔｅｐ１０７で共振回転速度ωsを元に起動パターンを再決定し，運転を継続する。 FIG. 8 is a flowchart showing the control of this embodiment. The dehydrating operation is started, and first, the resonance rotational speed ω s recorded in the rotational speed recording unit 49 is referred to (Step 101). Here, the resonance rotational speed ω s is the rotational speed of the drum when the eigenvalue input means 5 is pressed in the previous operation, and an initial value is recorded when the eigenvalue input means 5 has never been pressed. ing. In Step 102, the activation pattern of the drum 8 is selected based on the resonance rotational speed ω s . In accordance with the determined activation pattern, the rotational speed of the drum 8 is increased at Step 103. The vibration amount measured by the vibration sensor 10e in Step 104 is compared with a predetermined determination value. If the vibration amount is small, the process proceeds to Step 105. If the vibration amount is large, the rotation of the drum 8 is stopped and restarted. Do. If the eigenvalue input means 5 is not pressed in Step 105, the process proceeds to Step 108. When the eigenvalue input means 5 is pressed in Step 105, the rotational speed ω at that time is recorded as the resonant rotational speed ω s (Step 106). In Step 107, the starting pattern is determined again based on the resonance rotational speed ω s and the operation is continued.
Ｓｔｅｐ１０８でドラム８の回転速度と最終脱水回転速度を比較し，最終脱水回転速度に到達している場合には，Ｓｔｅｐ１０９に進み，到達していない場合にはＳｔｅｐ１０５に戻り，ドラム８の回転速度を上昇させる。Ｓｔｅｐ１０９では，経過時間と設定時間を比較し，経過時間が大きい場合には，ドラム８の回転を停止し，運転を終了する。経過時間の方が短い場合は，設定時間以上となるまで，脱水を継続する。 In Step 108, the rotational speed of the drum 8 is compared with the final dewatering rotational speed. If the final dewatering rotational speed is reached, the process proceeds to Step 109. If not reached, the process returns to Step 105, and the rotational speed of the drum 8 is set. Raise. In Step 109, the elapsed time is compared with the set time. If the elapsed time is large, the rotation of the drum 8 is stopped and the operation is ended. If the elapsed time is shorter, continue dehydration until the set time is reached.
このように，洗濯機が設置されている部屋以外の床などの共振回転速度ωsを，使用者が固有値入力手段５を押下した時点でのドラム８の回転速度ωから求め，その回転速度で回転する時間を短縮することで，低振動な運転を実現する事ができる。また，共振回転速度ωsの入力は，必ずしも固有値入力手段５を押下したタイミングだけでなく，時刻を入力し，その時の回転速度ωを共振回転速度ωsとしてもよい。また，共振回転速度ωsを直接入力してもよい。この場合，洗濯機にドラム８の回転速度を表示する表示手段を有することがより望ましい。 Thus, the resonance rotational speed ω s of the floor other than the room where the washing machine is installed is obtained from the rotational speed ω of the drum 8 when the user depresses the eigenvalue input means 5, and the rotational speed is By reducing the rotation time, low vibration operation can be realized. The resonance rotational speed ω s may be input not only at the timing when the eigenvalue input means 5 is pressed, but also by inputting the time, and the rotational speed ω at that time may be used as the resonant rotational speed ω s . Further, the resonance rotational speed ω s may be directly input. In this case, it is more desirable to have display means for displaying the rotational speed of the drum 8 in the washing machine.
また，必ずしも最終脱水回転速度までドラム８の回転速度を上昇させる必要はなく，最終脱水回転速度付近などで固有値入力手段５が押下された場合は，ドラム８の回転速度を低下させ，振動や騒音を低減してもよい。 Further, it is not always necessary to increase the rotational speed of the drum 8 up to the final dewatering rotational speed. When the eigenvalue input means 5 is pressed near the final dewatering rotational speed, the rotational speed of the drum 8 is decreased to reduce vibration and noise. May be reduced.
例えば，所定の回転速度で脱水運転を行っている際に，使用者が居間の床の振動が大きいと感じた際に，固有値入力手段５を押下する。洗濯機は，固有値入力手段が押下された時のドラム８の回転速度を共振回転速度ωsとして記録する。洗濯機は共振回転速度ωsに対して，所定の範囲の回転速度で回転する時間を短縮するため，ドラム８の回転速度を減少もしくは向上させることで避共振化を行うことができ，居間の床の振動を下げることができる。また，この回転速度を記録しているため，以降の運転においても同様に，居間の床の共振回転速度ωsでドラム８が回転する時間を短縮する事が出来る。このように，本実施形態の洗濯機の制御では，洗濯機の運転中にされた入力によって，ドラム８の回転速度の上昇率，減速率，所定の回転速度で回転する時間を変えることができる。なお、固有値入力手段５が操作された場合に、その時点におけるドラム８の回転速度から低下させて、その回転速度を超えない回転速度で以降の脱水運転を継続させるようにしても良い。 For example, when performing a dehydration operation at a predetermined rotation speed, when the user feels that the floor vibration in the living room is large, the eigenvalue input means 5 is pressed. The washing machine records the rotation speed of the drum 8 when the eigenvalue input means is pressed as the resonance rotation speed ω s . Since the washing machine shortens the time for rotating at a rotational speed within a predetermined range with respect to the resonant rotational speed ω s , the resonance speed can be reduced by decreasing or improving the rotational speed of the drum 8, and the living room Floor vibration can be reduced. In addition, since the rotational speed is recorded, the time during which the drum 8 rotates at the resonance rotational speed ω s of the floor in the living room can be shortened in the subsequent operation as well. As described above, in the control of the washing machine according to the present embodiment, the rate of increase in the rotational speed of the drum 8, the deceleration rate, and the time during which the drum 8 rotates at a predetermined rotational speed can be changed by the input made during the operation of the washing machine. . When the eigenvalue input means 5 is operated, the subsequent dehydrating operation may be continued at a rotational speed that does not exceed the rotational speed by reducing the rotational speed of the drum 8 at that time.
また，記録するドラム８の回転速度は１つである必要はない。入力された共振回転速度を複数回分記録し，その値から基準となる共振回転速度を決定してもよい。本実施形態の洗濯機では，固有値入力手段５による入力によって，脱水時のドラムの起動パターン，すなわちドラム８の回転速度，回転速度の上昇率，回転速度の減速率，所定の回転速度で回転する時間の少なくとも一つを変更する。 Further, the recording drum 8 need not have a single rotational speed. The input resonance rotational speed may be recorded for a plurality of times, and the reference resonance rotational speed may be determined from the recorded value. In the washing machine of the present embodiment, the drum start pattern during dehydration, that is, the rotation speed of the drum 8, the increase rate of the rotation speed, the reduction rate of the rotation speed, and the predetermined rotation speed are rotated by the input by the eigenvalue input means 5. Change at least one of the times.
本実施形態では，ドラム式洗濯機について述べたが，必ずしもドラム式洗濯機である必要はなく，縦型洗濯機でもよい。なお，洗濯機の設置場所を変更した場合には，設置環境が変化するため，記録している共振回転速度をリセットする手段を設けている。 Although the drum type washing machine has been described in the present embodiment, the drum type washing machine is not necessarily a drum type washing machine, and may be a vertical washing machine. Note that when the installation location of the washing machine is changed, the installation environment changes. Therefore, means for resetting the recorded resonance rotational speed is provided.
＜実施形態２＞
第２の実施形態の洗濯機は，運転中に入力する事が出来る入力手段である振動量入力手段５１を有し，振動量入力手段５１が押下された時の振動量を記録する振動量記録手段５２を有し，該振動量記録手段５２に記録されている振動量に応じて，アンバランス量判定を行う際の判定値を決定するものである。振動量入力手段５１を押下することで，判定値を変更し，それ以上振動が大きくならないように制御する。従って，使用者は洗濯機の振動が大きいと感じた際に，振動量入力手段５１を押下することで，運転時の振動を低下させることが可能となる。
<Embodiment 2>
The washing machine of the second embodiment has vibration amount input means 51 that is an input means that can be input during operation, and records vibration amount when the vibration amount input means 51 is pressed. Means 52 is provided, and a determination value for determining the unbalance amount is determined according to the vibration amount recorded in the vibration amount recording means 52. By pressing the vibration amount input means 51, the determination value is changed, and control is performed so that the vibration does not increase any more. Therefore, when the user feels that the vibration of the washing machine is large, the vibration during driving can be reduced by pressing the vibration amount input means 51.
脱水運転時には，ドラム内に不均一に存在する衣類の偏りに起因するアンバランスが大きいと，アンバランスに発生する遠心力により外槽の振動が過大になる。そこで，外槽の振動が過大になることを防止するために，外槽の振動を振動センサで検出し，アンバランス量を過大であるか判断するアンバランス量判定を行う。アンバランス量判定でアンバランス量が過大と判断した場合にはドラム８の回転を停止し，再度起動する。これにより，振動が過大となるのを防止している。このアンバランス量判定時にアンバランス量が過大であるか判断する基準である判定値を低下させれば，より小さい振動しか発生しなくなる。しかし，アンバランス量判定時の判定値を下げて，発生する振動の上限を低下させると，衣類のバランスを取る工程に掛かる時間が長くなるというデメリットが生じる。そこで，アンバランス量判定をする際の判定値は使用者が許容できる振動量以下に制限でき，かつその範囲でより大きな値とすることが望ましい。これにより，振動の低減だけでなく，衣類を均一にドラム内に張り付ける工程，及び不均一に張り付いた衣類を均一に修正する工程に掛かる時間が必要以上に延長することを防止することができる。 During the dehydration operation, if there is a large unbalance due to uneven clothing in the drum, the vibration of the outer tub will be excessive due to the centrifugal force generated in the unbalance. Therefore, in order to prevent the vibration of the outer tank from becoming excessive, the vibration of the outer tank is detected by a vibration sensor, and an unbalance amount determination is performed to determine whether the unbalance amount is excessive. When it is determined that the unbalance amount is excessive in the unbalance amount determination, the rotation of the drum 8 is stopped and restarted. This prevents excessive vibration. If the determination value, which is a reference for determining whether the unbalance amount is excessive, is reduced at the time of determining the unbalance amount, only smaller vibrations are generated. However, if the determination value at the time of determining the unbalance amount is lowered to reduce the upper limit of the generated vibration, there is a demerit that the time required for the process of balancing clothes becomes longer. Therefore, it is desirable that the determination value for determining the unbalance amount can be limited to a vibration amount that can be tolerated by the user or a larger value within that range. This not only reduces vibration, but also prevents the time required for the process of evenly attaching the clothes in the drum and the process of correcting the unevenly attached clothes from being unnecessarily prolonged. it can.
従来の洗濯機では，標準となる制御パターン（標準モード）の他に，振動や騒音を小さく抑えたい使用者のために，より静かな運転を行う静音モードなどが提案されている。これは，使用者が静かな運転を行いたい場合に，静音モードを選択することで，標準モードに比べて低振動な運転を行うものである。この場合，静音モードのアンバランス量判定時の判定値を標準モードに比べて小さくし，脱水を行う際に高速まで起動するアンバランス量を小さくなるように制限する。これにより，振動が小さくなり，騒音が低下する。また，他の方法として，脱水時の最高回転速度を低くする方法があり，一般的に騒音はドラムの回転速度が高い程大きくなる傾向があるため，最高回転速度を低く設定するとことで，発生するアンバランス量が同程度であるとしても，騒音値を小さくすることができる。 In conventional washing machines, in addition to the standard control pattern (standard mode), a quiet mode for quieter operation has been proposed for users who want to reduce vibration and noise. In this case, when the user wants to perform a quiet operation, the quiet mode is selected to perform a low vibration operation compared to the standard mode. In this case, the determination value at the time of determining the unbalance amount in the silent mode is made smaller than that in the standard mode, and the unbalance amount to be started up to a high speed when dehydrating is limited to be small. This reduces vibration and reduces noise. Another method is to lower the maximum rotation speed during dehydration. Generally, noise tends to increase as the drum rotation speed increases. Even if the amount of unbalance to be performed is similar, the noise value can be reduced.
しかしながら，脱水時の振動は洗濯機自体の振動以外にも，洗濯機が設置されている部屋の床や，洗濯機が設置されている部屋とは異なる部屋の床の振動など複数存在する。例えば静音モードを選択することで，振動を低減することが可能となるが，低減したい振動の種類に係わらずアンバランス量判定を行う際の判定値を低下させるため，低減したい振動以外の振動も併せて低減する事になる。この場合必要以上に判定値を低下させることになるため，衣類を均一にドラム内に張り付ける工程，及び不均一に張り付いた衣類を均一に修正する工程に掛かる時間が長くなる。例えば，洗濯機を設置している床の共振が高速脱水時に発生し，使用者が振動を過大と感じた場合，高速脱水時の判定値のみ低下させることが望ましい。これにより低速時の判定値は変わらないため，衣類を均一にドラム内に張り付ける工程，及び不均一に張り付いた衣類を均一に修正する工程が必要以上に延長するのを防止できる。しかし，静音モードを選択すると回転速度領域に係わらず判定値を低下させるため，低速時の判定値も低下し，衣類のバランスを取るための工程に時間がより長くかかってしまう。また，最高回転速度を低下させる方法に関しても，衣類の片寄りが小さい場合でもドラムの回転速度を低下させるため，全ての場合において脱水性能が低下するという課題がある。 However, in addition to the vibration of the washing machine itself, there are a plurality of vibrations during dehydration, such as the floor of the room where the washing machine is installed and the vibration of the floor of a room different from the room where the washing machine is installed. For example, it is possible to reduce the vibration by selecting the silent mode. However, since the determination value when performing the unbalance amount determination is reduced regardless of the type of vibration to be reduced, vibration other than the vibration to be reduced is also possible. It will also be reduced. In this case, since the judgment value is lowered more than necessary, the time required for the process of uniformly attaching the garment in the drum and the process of uniformly correcting the non-uniformly attached garment increases. For example, if the floor where the washing machine is installed resonates during high-speed dewatering and the user feels excessive vibration, it is desirable to reduce only the judgment value during high-speed dewatering. As a result, the judgment value at low speed does not change, so that it is possible to prevent the process of evenly attaching the clothes in the drum and the process of uniformly correcting the unevenly attached clothes from being extended more than necessary. However, when the silent mode is selected, the determination value is decreased regardless of the rotation speed region, so that the determination value at low speed is also decreased, and the process for balancing clothes takes longer. Further, regarding the method of reducing the maximum rotation speed, there is a problem that the dewatering performance is lowered in all cases because the rotation speed of the drum is reduced even when the deviation of the clothing is small.
そこで本実施形態に係わる洗濯機は，使用者が許容する事が出来る振動量を回転速度と併せて入力することで，必要最小限に振動レベルを制限することができるため，使用者が許容することが可能な振動量に抑え，かつ衣類のバランスを取る工程の時間を短くすることができる。ここで，使用者が許容することができる振動量を直接数値として入力する事は困難であるため，本実施形態における洗濯機は運転中に振動量入力手段５１を押下された時の振動量とドラム８の回転速度を記録する。この振動量を使用者が許容できない振動量と判断し，それより小さい値を振動量入力手段５１が押下された回転速度での判定値とする。これにより，使用者が直接数値を入力することなく，使用者が許容可能な振動量を洗濯機に入力することが出来る。このようにすることで，使用者が大きいと判断した時の振動量を記録することが可能となり，この時の回転速度の振動量を使用者の許容量以下に抑えることができる。 Therefore, the washing machine according to the present embodiment allows the user to allow the vibration level that can be allowed by the user, together with the rotation speed, to limit the vibration level to the minimum necessary. It is possible to reduce the amount of vibration that can be performed and to shorten the time of the process of balancing clothes. Here, since it is difficult to directly input the vibration amount that can be allowed by the user as a numerical value, the washing machine in the present embodiment has the vibration amount when the vibration amount input means 51 is pressed during operation. Record the rotation speed of the drum 8. This amount of vibration is determined as an amount of vibration that the user cannot tolerate, and a smaller value is set as a determination value at the rotational speed at which the vibration amount input means 51 is pressed. Thereby, the user can input an allowable vibration amount into the washing machine without directly inputting a numerical value. By doing so, it becomes possible to record the amount of vibration when the user determines that it is large, and the amount of vibration of the rotational speed at this time can be suppressed below the allowable amount of the user.
図９に第２の実施形態のブロック図を示す。振動量入力手段５１が押下された際には，振動センサ１０ｅの出力である振動量Vとドラム８の回転速度ωを振動量記録部５２に記録する。判定値設定部５３は振動量記録部５２に記録されている回転速度および振動量と，起動パターンデータベース４４を比較し，判定値を決定する。 FIG. 9 shows a block diagram of the second embodiment. When the vibration amount input means 51 is pressed, the vibration amount V that is the output of the vibration sensor 10e and the rotational speed ω of the drum 8 are recorded in the vibration amount recording section 52. The determination value setting unit 53 compares the rotation speed and vibration amount recorded in the vibration amount recording unit 52 with the activation pattern database 44 to determine a determination value.
第２の実施形態の制御方法を図１０に示すフローチャートを用いて説明する。脱水運転を開始し，まず振動起動パターン記録部５０に記録されている回転速度，振動量を参照し（Ｓｔｅｐ２０１），Ｓｔｅｐ２０２で回転速度，振動量を元にアンバランス量を判定する際の判定値V1，V2を決定する。予め記録されている起動パターンに従い，Ｓｔｅｐ２０３でドラム８の回転速度を上昇させる。Ｓｔｅｐ２０４で振動量VとＳｔｅｐ２０２で決定した判定値V1を比較し，振動量Vが小さい場合はＳｔｅｐ２０５に進み，振動量Vが大きい場合は，ドラム８の回転を停止し，再起動を行う。Ｓｔｅｐ２０５で振動量入力手段５１が押下されない場合には，Ｓｔｅｐ２０７進む。Ｓｔｅｐ２０５で振動量入力手段５１が押下された場合には，その時の回転速度ωと，振動量Vを記録し，判定値V1を再決定し，運転を継続する（Ｓｔｅｐ２０６）。 A control method according to the second embodiment will be described with reference to a flowchart shown in FIG. Reference value when starting the dehydration operation and referring to the rotational speed and vibration amount recorded in the vibration activation pattern recording unit 50 (Step 201) and determining the unbalance amount based on the rotational speed and vibration amount at Step 202 Determine V 1 and V 2 . In step 203, the rotational speed of the drum 8 is increased in accordance with the activation pattern recorded in advance. It compares the determination value V 1 determined in the vibration amount V and Step202 in Step 204, when the vibration amount V is smaller proceeds to Step205, when vibration amount V is large, and stops the rotation of the drum 8, to reboot. If the vibration amount input means 51 is not pressed at Step 205, the process proceeds to Step 207. When the vibration amount input means 51 is pressed in Step 205, the rotational speed ω and the vibration amount V at that time are recorded, the determination value V 1 is determined again, and the operation is continued (Step 206).
Ｓｔｅｐ２０７でドラムの回転速度ωが所定の回転速度ω1と比較し，小さい場合はＳｔｅｐ２０３に戻り，大きい場合はＳｔｅｐ２０８に進み，ドラムの回転速度を上昇させる。Ｓｔｅｐ２０９で振動量判定２を行い，振動量Vと判定値V2を比較し，小さい場合はＳｔｅｐ２１０に進み，大きい場合はＳｔｅｐ２１３に進む。Ｓｔｅｐ２１０で振動量入力手段５１が押下された場合には，Ｓｔｅｐ２１１でその時の回転速度ωと，振動量Vを記録し，判定値V2を再決定して，運転を継続する。Ｓｔｅｐ２１２で回転速度ωと最終脱水回転速度を比較し，回転速度ωの方が小さい場合はＳｔｅｐ２０８に戻る。Ｓｔｅｐ２１３で経過時間と設定時間を比較し，経過時間の方が大きい場合はドラムの回転を停止し，運転を終了する。 In Step 207, the drum rotational speed ω is compared with the predetermined rotational speed ω 1, and if it is smaller, the process returns to Step 203, and if larger, the process proceeds to Step 208 to increase the drum rotational speed. Perform vibration amount determination 2 in Step 209, compares the determination value V 2 and the vibration amount V, is less proceeds to Step 210, if it is greater, the process proceeds to Step213. If the amount of vibration input means 51 is pressed in Step210, the rotational speed ω at that time in Step 211, and records the vibration amount V, and re-determines the determination value V 2, to continue the operation. In Step 212, the rotational speed ω is compared with the final dewatering rotational speed. If the rotational speed ω is smaller, the process returns to Step 208. In Step 213, the elapsed time is compared with the set time. If the elapsed time is longer, the drum rotation is stopped and the operation is terminated.
人が感じる振動は，振動変位の大きさ以外に，周波数によっても感じ方が異なるため，判定値V1，V2をドラム８の回転速度ごとに設けることで，より振動の小さい運転を行うことができる。 Since vibrations felt by humans differ depending on the frequency in addition to the magnitude of the vibration displacement, the determination values V 1 and V 2 are set for each rotation speed of the drum 8 to perform operation with less vibration. Can do.
高速時の判定値を小さくすることで，判定値以上の振動が発生した場合に上昇させる回転速度を低く制限し，振動を小さくすることができるが，回転速度が低くなるため脱水性能が低下する。本発明の制御を用いることで，使用者が許容できる範囲に振動の大きさを抑えながら，高い回転速度で脱水する事ができ，振動の大きさと脱水性能を両立することができる。 By reducing the judgment value at high speed, the rotational speed to be increased when vibration exceeding the judgment value can be limited to lower the vibration, but the rotational speed is lowered, so the dewatering performance is reduced. . By using the control of the present invention, it is possible to perform dehydration at a high rotational speed while suppressing the magnitude of vibration within a range acceptable by the user, and it is possible to achieve both the magnitude of vibration and dewatering performance.
このような制御をすることにより，所定の回転速度で振動量が大きいと入力された場合には，以降の運転において，大きいと判断した際の回転速度領域において振動量，すなわち衣類の片寄りの大きさと同等以上の片寄りが発生した場合は，最終的な回転速度を低く設定することになり，振動を低減することができる。例えば，布偏りを模擬した任意の重りを設置して脱水を行った際に，振動量入力手段５１を用いて振動量が大きいと入力された場合，一度運転を停止し，再度布偏りを模擬した重りを同様に設置したまま脱水運転を行った時には，振動量入力手段５１を押下した時のドラムの回転速度よりも，振動が小さくなる回転速度（例えば，振動量入力手段５１が押下された時の回転速度よりも１００ｒ／ｍｉｎ低い回転速度）までしか上昇しない。一方，布偏りを模擬した重りの量を小さくした場合は，振動量入力手段５１が押下された時のドラム８の回転速度を基準に，例えば±１００ｒ／ｍｉｎの範囲では，回転速度の上昇率を高くして通過させ，より高い回転速度で脱水を行うことができる。 By performing such control, when it is input that the amount of vibration is large at a predetermined rotational speed, the amount of vibration in the rotational speed region when it is determined to be large in the subsequent operation, that is, the deviation of clothing. If a deviation equal to or greater than the size occurs, the final rotational speed is set low, and vibration can be reduced. For example, when dewatering is performed by installing an arbitrary weight simulating cloth bias, if a large vibration amount is input using the vibration amount input means 51, the operation is stopped once and the cloth bias is simulated again. When the dewatering operation is performed with the weights set in the same manner, the rotational speed at which the vibration is smaller than the rotational speed of the drum when the vibration amount input means 51 is pressed (for example, the vibration amount input means 51 is pressed). The rotation speed is only 100 r / min lower than the rotation speed at the time). On the other hand, when the weight amount simulating the cloth bias is reduced, the rate of increase in the rotational speed is, for example, within a range of ± 100 r / min, based on the rotational speed of the drum 8 when the vibration amount input means 51 is pressed. Can be dehydrated at a higher rotational speed.
一方，振動量入力手段５１を押下した時のドラムの回転速度付近の回転速度の判定値を変更するため，回転速度が大きく異なる領域については，アンバランス量判定に関して変更はない。例えば，高速脱水時（１２００ｒ／ｍｉｎ）に振動量入力手段５１が押下された場合は，外槽の共振回転速度などの低い回転速度（例えば，２００ｒ／ｍｉｎ）でのアンバランス量判定値は変更しないため，衣類を模擬した重りの量が同じであれば，高速脱水時は回転速度を変更するが，低い回転速度では制御の変更は行わない。このように，振動量入力手段５１が押下された時の回転速度と振動量を基準としてアンバランス量判定やドラムの回転速度制御を行うため，洗濯機の振動や，床などの家の各部の振動を小さく抑えることが可能となる。 On the other hand, since the determination value of the rotation speed near the rotation speed of the drum when the vibration amount input means 51 is pressed is changed, there is no change in the unbalance amount determination in the region where the rotation speed is greatly different. For example, when the vibration amount input means 51 is pressed during high-speed dewatering (1200 r / min), the unbalance amount determination value at a low rotation speed (for example, 200 r / min) such as the resonance rotation speed of the outer tub is changed. Therefore, if the amount of weight simulating clothing is the same, the rotational speed is changed during high-speed dewatering, but the control is not changed at a low rotational speed. Thus, in order to perform unbalance amount determination and drum rotation speed control based on the rotation speed and vibration amount when the vibration amount input means 51 is pressed, the vibration of the washing machine, the floor and other parts of the house are controlled. Vibration can be suppressed to a small level.
また，必ずしも振動が大きいと感じた時に振動量入力手段５１を押下する必要はなく，運転終了後などにその時の運転で振動が大きかったことをその時の時刻を振動量入力手段５１で入力することで，その時刻での振動量を基準に判定値を決定してもよい。これにより，振動が大きいと感じた際に，洗濯機の近くにいない場合でも，入力が容易になる。また，時刻入力以外に，脱水時の回転速度を複数の段階に分け，それを入力するようにしてもよい。例えば，脱水時のドラムの回転速度が６００ｒ／ｍｉｎ以下の加速中，６００ｒ／ｍｉｎ以上の高速脱水中などに分けることでも，目的となる振動モードを判別する事が可能となるため，必要な回転速度領域のみ判定値を変更する事が可能になる。また，操作・表示パネル３にドラムの回転速度と振動量を表示するようにし，その値を使用者がメモするなどし，運転終了後などに回転速度と振動量を入力するようにしてもよい。 Further, it is not always necessary to press the vibration amount input means 51 when it is felt that the vibration is large, and the vibration amount input means 51 inputs that the vibration was large in the operation at that time after the end of the operation. Thus, the determination value may be determined based on the vibration amount at that time. This makes it easy to input even if you are not near the washing machine when you feel that the vibration is high. Besides the time input, the rotational speed during dehydration may be divided into a plurality of stages and input. For example, it is possible to determine the target vibration mode by dividing the rotation speed of the drum during dehydration during acceleration of 600 r / min or less and during high-speed dehydration of 600 r / min or more. The judgment value can be changed only in the speed region. Alternatively, the rotation speed and vibration amount of the drum may be displayed on the operation / display panel 3, and the values may be noted by the user, and the rotation speed and vibration amount may be input after the operation is completed. .
＜実施形態３＞
次に第３の実施形態について図１１に示すブロック図を用いて説明する。本実施形態に係わる洗濯機は，外部機器２０１との通信手段２０２を有し，外部機器２０１によって測定された振動加速度や騒音値などの情報の入力を可能にする。ここで，外部機器とは，加速度センサや騒音計を有したものであり，通信手段２０２とは無線，有線のどちらでもよい。外部機器２０１と通信手段が一体であるものの一例として，ＵＳＢなどの接続ポートを有する加速度センサや無線内蔵の加速度センサ，さらに携帯電話やスマートフォンなどがある。
<Embodiment 3>
Next, a third embodiment will be described with reference to the block diagram shown in FIG. The washing machine according to the present embodiment includes a communication unit 202 with the external device 201, and enables input of information such as vibration acceleration and noise value measured by the external device 201. Here, the external device has an acceleration sensor and a sound level meter, and the communication means 202 may be either wireless or wired. As an example in which the external device 201 and the communication unit are integrated, there are an acceleration sensor having a connection port such as a USB, a wireless built-in acceleration sensor, a mobile phone, a smartphone, and the like.
振動検出手段を備えた外部機器２０１を居住空間の床などの洗濯機が運転している際に振動が気になる位置に設置し，洗濯機を運転した時の振動を計測し，記録する。記録した振動データを洗濯機２００に入力する。洗濯機２００は入力された振動データから固有値を計算し，その固有値と同じドラム８の回転速度で回転する時間を短縮する。このように使用者が気になる振動を直接測定することで，洗濯機が設置されている空間の振動だけでなく，家自体が共振し，振動が大きくなることを防止する事ができる。ここで，外部機器２０１は必ずしも測定した振動を記録する必要はなく，常にデータを転送する形式でもよい。 An external device 201 having vibration detection means is installed at a position where vibration is anxious when the washing machine such as a floor in a living space is operating, and the vibration when the washing machine is operated is measured and recorded. The recorded vibration data is input to the washing machine 200. The washing machine 200 calculates an eigenvalue from the input vibration data, and shortens the time for rotation at the same rotation speed of the drum 8 as the eigenvalue. In this way, by directly measuring the vibration that the user is interested in, it is possible to prevent not only the vibration of the space in which the washing machine is installed, but also the house itself from resonating and increasing the vibration. Here, the external device 201 does not necessarily have to record the measured vibration, and may be in a format that always transfers data.
また，必ずしも測定した振動波形を洗濯機に入力する必要はなく，外部機器２０１が振動波形から共振回転速度を算出し，算出された固有値を操作・表示パネル３にある固有値入力手段２０３を使って，直接入力してもよい。この場合，固有値入力手段２０３は数値を入力する手段を有する。本実施形態のブロック図において，通信手段２０２を操作・表示パネル３の外に設ける構成としているが，操作・表示パネル３上に設けてもよい。 Further, it is not always necessary to input the measured vibration waveform to the washing machine. The external device 201 calculates the resonance rotational speed from the vibration waveform, and uses the calculated eigenvalue using the eigenvalue input means 203 on the operation / display panel 3. , You may enter directly. In this case, the eigenvalue input means 203 has means for inputting numerical values. In the block diagram of the present embodiment, the communication unit 202 is provided outside the operation / display panel 3, but may be provided on the operation / display panel 3.
また，外部機器２０１を筺体１に設置し，筺体１の振動を測定することで，筺体１の共振回転速度を検出する事ができ，前記共振回転速度付近の回転速度で運転する時間を短縮することで低振動の運転が可能となる。ここで，外部機器２０１の固定が重要であり，筺体１と外部機器２０１に隙間があると，その隙間による振動を筺体１の振動と誤検知する可能性がある。そこで，筺体１上部の構造を拡大して図である図１２に示すように，筺体１の上部に外部機器２０１を接続するためのセンサ固定部２０３で固定することで，誤検知を低減する事が可能になる。 Further, by installing the external device 201 on the housing 1 and measuring the vibration of the housing 1, the resonance rotational speed of the housing 1 can be detected, and the operation time at the rotational speed near the resonance rotational speed can be shortened. This enables low vibration operation. Here, it is important to fix the external device 201. If there is a gap between the housing 1 and the external device 201, vibration due to the gap may be erroneously detected as vibration of the housing 1. Therefore, as shown in FIG. 12 which is an enlarged view of the structure of the upper portion of the housing 1, fixing by a sensor fixing portion 203 for connecting the external device 201 to the upper portion of the housing 1 can reduce false detection. Is possible.
＜実施形態４＞
本実施形態の洗濯機は，洗濯機の設置環境を入力する設置環境入力手段を有し，設置環境から筺体や床などの共振回転速度を求め記録し，記録されている共振回転速度付近の回転速度でドラムが回転する時間を短縮する。これにより，共振によって振動が大きくなった状態で運転する時間を短縮する事ができ，より低振動な運転を行う事ができる。床が柔らかく，共振回転速度が低い場合には，共振回転速度を通過する際のドラムの回転速度の上昇率を向上させ，より高い回転速度に上昇させて脱水することで，脱水時間の延長を伴わず，脱水後の衣類が含む水の量を極力低減する運転を行う事ができる。
<Embodiment 4>
The washing machine of this embodiment has an installation environment input means for inputting the installation environment of the washing machine, obtains and records the resonance rotational speed of the housing, floor, etc. from the installation environment, and rotates around the recorded resonance rotational speed. Reduce the time the drum rotates at speed. As a result, it is possible to shorten the operation time in a state where the vibration is increased due to resonance, and it is possible to perform operation with lower vibration. If the floor is soft and the resonant rotational speed is low, the rate of increase in the rotational speed of the drum when passing through the resonant rotational speed is improved, and the dehydration time is extended by increasing the rotational speed to a higher rotational speed. Without being accompanied, it can be operated to reduce the amount of water contained in clothing after dehydration as much as possible.
運転の流れについて説明する。電源投入後に，設置環境入力手段を用いて，家の構造の種類や洗濯機が設置された階層，何階建てかなどを入力する。洗濯機は入力された設置環境とマイコン内の設置環境データベースを比較し，床などの共振回転速度を求める。運転を開始し，得られた共振回転速度でドラムが回転する時間を短縮するような，つまり回転速度の上昇率を向上させる起動パターンを設定する。ドラムを駆動する駆動機構は，設定された起動パターンに基づき，ドラムの回転速度を上昇させる。共振回転速度付近では，回転速度を一定にする時間を短縮し，回転速度の上昇率を高くする。 The operation flow will be described. After the power is turned on, the installation environment input means is used to input the type of house structure, the level where the washing machine is installed, and how many stories it is. The washing machine compares the input installation environment with the installation environment database in the microcomputer, and obtains the resonance rotational speed of the floor and the like. Start the operation and set a start pattern that shortens the drum rotation time at the obtained resonance rotation speed, that is, increases the rate of increase of the rotation speed. The drive mechanism for driving the drum increases the rotational speed of the drum based on the set start pattern. In the vicinity of the resonance rotational speed, the time for keeping the rotational speed constant is shortened and the rate of increase in rotational speed is increased.
例えば，設置環境入力手段を用いて，鉄筋，木造などの家の構造の種類や，洗濯機を設置する階層などを入力する。ここで，木造，２階建て，洗濯機を１階に設置と入力する。洗濯機はその設置環境と設置環境データベースを比較して，共振回転速度（例えば６００ｒ／ｍｉｎ）を求める。脱水運転時には６００ｒ／ｍｉｎ付近で回転する時間を短縮し，最終的には最高脱水回転速度に到達するように制御する。 For example, the installation environment input means is used to input the type of house structure such as a reinforcing bar or wooden structure, the level where the washing machine is installed, and the like. Here, it is input that a wooden structure, a two-story building, and a washing machine are installed on the first floor. The washing machine compares the installation environment with the installation environment database, and obtains a resonance rotational speed (for example, 600 r / min). At the time of dehydration operation, the rotation time near 600 r / min is shortened, and finally control is performed so as to reach the maximum dehydration rotation speed.
このように，設置環境で最終的な回転速度を変更するのではなく，共振回転速度を避ける運転をするため，脱水回転速度が低下することによる運転時間の延長を伴わずに衣類の水分量を極力低減できるため，洗濯時には衣類を干す時間の延長を抑制する。又，洗濯乾燥機における衣類の水分量を極力減らして乾燥運転を行えるので，衣類の乾燥に必要な消費電力量が増加するのを防止する事が出来る。 In this way, instead of changing the final rotational speed in the installation environment, in order to avoid the resonant rotational speed, the moisture content of the clothing can be reduced without extending the operating time due to a decrease in the spin speed. Since it can be reduced as much as possible, it prevents the time for clothes to be dried during washing. Moreover, since the moisture content of the clothes in the washing / drying machine can be reduced as much as possible and the drying operation can be performed, it is possible to prevent an increase in power consumption necessary for drying the clothes.
