This rotation transmission section (12) has a double drive shaft (12a) (12b) that is switched by a spring clutch mechanism (13), and the outer drive shaft (12a) is connected to the inner drive shaft (12a). The drive shafts (12b) are each coupled to an agitator (1).
なお図示は省略するがこれらの機構は、すべて防振手段

設けられている。Although not shown in the drawings, all of these mechanisms are housed inside the exterior via vibration isolating means, and an operating section containing a control device using a microcomputer and operation switches is provided at the top of the exterior.

Put the laundry, water, and detergent into the dehydration tank (4) and turn on the power.
When N is turned on, the motor (8) rotates forward and reverse alternately, and the azimuth data (1) also oscillates accordingly. After the operation takes a certain period of time due to the action of a timer in the control device, the water is drained and the process moves on to the dewatering process.
ところで、脱水の工程に入るとハネクラッチ機構（１３

ター（８）の回転数が極数によって決定される。By the way, when the dewatering process begins, the honey clutch mechanism (13
), the shaft (12a) rotates together with the switching shaft (12b), and the motor (8) continuously rotates in only one direction. Along with this, pulley (9), belt (10)
), the dehydration tank (4) rotates via the pulley (11) rotation transmission part (12), and the rotation speed of the dehydration tank (4) is given by the reduction ratio of the pulleys (9) and (11). The number of rotations of the motor (8) is determined by the number of poles.
誘導電動機では回転数は９００回転／分となり、この回
転数で脱水運転が開始される。The rotation speed of the induction motor is 900 rpm, and the dehydration operation is started at this rotation speed.
しかし、このような従来の脱水運転方法は、脱水槽（４

吸収しきれないものである。However, such conventional dehydration operation method requires only 4 dehydration tanks (4
) is set to reach a high speed of 900 revolutions/minute immediately after the start of rotation, so the dehydration tank (4)
A large centrifugal force suddenly acts on the items to be washed inside the dehydration tank (4), causing the items to be washed to one side in the dehydration tank (4), often resulting in large vibrations and noise. Such vibrations cannot be absorbed even by the balancer (6) provided at the upper opening of the dehydration tank (4).

時、一時的に回転数は下降するが、前記不都合を解消す
る回転数制御は行なえなかった。It is also conceivable to control the continuous rotation of the dehydration tank (4) by simply controlling the length of time that the motor 8) is energized, but in this method, the rotational force due to inertia depends on the amount of items to be washed. As a result, when the motor (8) is stopped, the rotation speed temporarily decreases, but it has not been possible to control the rotation speed to eliminate the above-mentioned disadvantage.
本発明の目的は前記従来例の不都合を解消し、脱水運転
時における被洗たく物の片寄りをなくし、大きな振動や
騒音の発生を防止できる洗たく機の脱水運転方法を提供
することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a dewatering operation method for a washing machine which eliminates the disadvantages of the conventional example, eliminates the unevenness of the laundry to be washed during dehydration operation, and prevents the generation of large vibrations and noises.
本発明は前記目的を達成するため、脱水工程の初期の段
階で、脱水槽を所定時間低速回転させた後、高速回転さ
せることを要旨とするものである。In order to achieve the above object, the gist of the present invention is to rotate the dehydration tank at a low speed for a predetermined period of time at an early stage of the dehydration process, and then to rotate it at a high speed.

振れる共振点以外の回転数で回転駆動されることとなり
、その結果脱水槽の回転は共振点以上にならず大きな振
れを引き起こさない。According to the present invention, at the initial stage of the dehydration process, the dehydration tank is rotated for a predetermined period of time, so the dehydration tank is driven to rotate at a rotation speed other than the resonance point where it vibrates the most. The rotation of the water tank does not exceed the resonance point and does not cause large vibrations.
また、この間に槽内の被洗たく物は水分がある程度除去
され、重量が軽減されるので、工程が進み高速回転によ

れや騒音も生じにくい。In addition, during this time, a certain amount of moisture is removed from the items to be washed in the tank, reducing their weight, so even as the process progresses to the dewatering process using high-speed rotation, there is less eccentric load and vibration and noise are less likely to occur. .

14) was installed, and the output from the detection means (14) was introduced into the control device. In the illustrated example, a speed generator using a power generation mechanism is used as the rotation speed detection means (14), but as another method, a rotary plate having a detection hole is attached to the shaft of the motor (8). It is also conceivable to combine an angle detector having a light emitting section and a light receiving section.

15). This AC clock circuit (17) is composed of a transformer (17a), resistors (17b) (17e), a diode (17C), and a transistor (17d).
このようにして第５図に示すような洗たく工程にしたが

。In this way, washing, rinsing, and dehydration are performed sequentially according to the washing process shown in Fig. 5. First, in the washing process, the items to be washed are stored in the dehydration tank (4), water, detergent, etc. and turn on the power switch, the motor (8
) rotates forward and reverse alternately, and the agitator (1) also swings accordingly. When the timer in the control device performs an operation that takes a certain period of time, water is drained and the washing process is completed.
次に、すすぎの工程に入り、注水脱水と通常のすすぎが
交互に繰り返される。このうち、注水脱水は、上方から
新しい水をふりかけながら被洗たく物内の洗剤を含んだ
水を排出するものである。Next, the rinsing process begins, and water injection and dehydration and normal rinsing are alternately repeated. Among these, water injection dehydration is a method in which water containing detergent from the item to be washed is discharged while sprinkling fresh water from above.

れる。When the water injection and dewatering process begins, the spring clutch mechanism (13) rotates the shaft (12a) together with the switching shaft (12b), and the motor (8) continuously rotates in only one direction. The motor (8) is energized to rotate the dehydration tank (4) and the agitator (1), but at the initial stage of this water injection and dewatering process, water injection is not yet performed. Then, the output from the rotation speed detection means (14) by the speed generator is transmitted to the control device (1
5), and on the other hand, in the AC clock circuit (17), an input in phase with the power supply frequency applied to the motor (8) is given to the transformer (17a), the voltage is stepped down by the transformer (17a), and the voltage is halved by the diode (17C). Wave clamp and resistance (1
7b) limits the current flowing into the transistor (17d), and the transistor (17d) and resistor (17e) shape the sine half wave into a rectangular wave that matches the input of the control device (15). It is input to the control device (15).
そして、脱水槽（４）が通常の高速回転である９００回

３で、その結果、誘導電動機であるモーター（８）の回
転数も１／３の回転数となり、脱水槽（４）の回転数も
通常の高速回転の１／３の低速回転となる。When the rotation speed of the motor (8) reaches a rotation speed such that the dehydration tank (4) reaches 300 rotations/minute, which is 1/3 of the normal high-speed rotation of 900 rotations/minute, the control device At step (15), the signal is output to the frequency converter (16), where only the shaded portion of the power supply frequency is applied to the motor (8) as shown in the waveform diagram of FIG. The frequency of the shaded part is 1/1 of the fundamental frequency 50/60Hz.
3, as a result, the rotation speed of the motor (8), which is an induction motor, becomes 1/3 of the rotation speed, and the rotation speed of the dehydration tank (4) also becomes low speed rotation, which is 1/3 of the normal high speed rotation.
こうして、脱水槽（４）内の被洗たく物は３００回転／
分の低速回転により所定時間脱水される。In this way, the items to be washed in the dehydration tank (4) rotate 300 times/
The water is dehydrated for a predetermined time by rotating at low speed for several minutes.
なお、この３００回転／分は、脱水槽（４）が一番大き
く振れる共振点以外の回転数ということで設定されたも
のでこれに限定されることなく、約３００〜４５０回転
／分の間で任意に設定でき、この低速回転による脱水槽
の運転を以下バランス回転と称する（第６図参照）。In addition, this 300 rotations/minute was set as the rotation speed other than the resonance point where the dehydration tank (4) vibrates the most, and is not limited to this, but is approximately between 300 and 450 rotations/minute. The operation of the dehydration tank at this low speed rotation is hereinafter referred to as balance rotation (see Fig. 6).
そして、バランス回転中は、共振点以下なので、被洗た
く物の片寄りが発生しにくく、また万一発生してもこれ
を修正する作用があり、大きな音や、振動を発するよう
な偏心回転になりにくく、このバランス回転中に被洗た
く物に含まれた水は約６０％排除され負荷が軽減される
。During balance rotation, the temperature is below the resonance point, so it is difficult for the objects to be washed to shift to one side, and even if it does occur, it has the effect of correcting this, and prevents eccentric rotation that produces loud noises and vibrations. Approximately 60% of the water contained in the items to be washed is removed during this balance rotation, reducing the load.
次いで、高速回転に入ると、また注水が開始され、モー

転中に減っているので、偏心による音や振動は、発生し
にくい。このバランス回転は第７図に示すようにすすぎ
工程の後の最終脱水工程においても行われる。Next, when high-speed rotation starts, water injection starts again, and the motor (8) is operated continuously, and the rotation speed of the dehydration tank (4) reaches 9.
The speed increases until it reaches 00 revolutions/minute. Even during such high-speed rotation, the water content of the items to be washed is reduced during the balance rotation, so noise and vibration due to eccentricity are unlikely to occur. This balance rotation is also performed in the final dewatering step after the rinsing step, as shown in FIG.
前記実施例では、モーター（８）を通常始動し、その回
転数を検知して、これが３００〜４５０回転／分に達し
たときに、この回転数で脱水槽（４）を低速回転維持さ

３００回転／分となるよう、洗たく開始時に操作部によ

転指令を与えておくこともできる。In the above embodiment, the motor (8) is normally started, its rotation speed is detected, and when the rotation speed reaches 300 to 450 rotations/minute, the dehydration tank (4) is maintained at a low speed rotation at this rotation speed. However, as another method, the control device (15) may be set in advance by the operating unit at the start of washing so that the rotation speed of the dehydration tank (4) is, for example, 300 rpm for a predetermined period of time at the initial stage of the water injection and dewatering process. It is also possible to input a low speed rotation command from the beginning of rotation.
そして、第１実施例と同様にして洗い工程に入り、これ
が終了して注水脱水工程に入ると、制御装置（１５）か
らの出力により、脱水槽（４）の回転数が３００回転／
分となるよう第１図に示すように周波数変換器（１６）
の働きで回転当初から制御される。Then, the washing process begins in the same manner as in the first embodiment, and when this ends and the water injection dehydration process begins, the rotation speed of the dehydration tank (4) is increased to 300 rpm by the output from the control device (15).
Frequency converter (16) as shown in Figure 1 to
is controlled from the beginning of rotation.

It can be applied to all types of washing machines that have a dehydration tank, such as whirlpool type washing machines.

With a simple method, it is possible to prevent the objects to be washed from shifting to one side during spin-drying, ensure low vibration and low noise during spin-drying, prevent the inconvenience of the spin-dry tank stopping midway, and make the operation proceed smoothly. .
