機に関する。[Detailed explanation of the invention] (a) Industrial application field The present invention is designed to stop the rotation of the dehydration tank using a control means and supply water sequentially when the washing/dehydration tank generates abnormal vibrations during the dehydration process. This invention relates to a fully automatic washing machine that executes an automatic unbalance correction program that rotates the rotor blades, drains water, and restarts rotation of the dehydration tank.

あつた。(b) Prior art This type of fully automatic washing machine is, for example,
This is shown in Publication No. 39889. In this conventional example, the rotor blades are intermittently reversed after water is supplied during an automatic correction program in order to eliminate the unbalanced load and unbalance of the laundry that causes abnormal vibrations. However, since this reversal loosening operation requires a large number of revolutions per rotation, the laundry is twisted in the opposite direction and hardened, making it difficult to correct imbalances.

のである。(E) Effect: When the laundry is rotated intermittently at one revolution or less, the laundry is shaken little by little, and the laundry that has piled up high is flattened. If you continue to do this from when the water level is sufficient until it drops to a low water level, not only will it take longer, but you will also be able to spread small items that tend to float and relatively light laundry evenly, so that the entire laundry will be in the tank. They are stacked almost uniformly and flat, reducing unbalanced loads.

る。 Next, the process will be explained based on FIG. 3. This fully automatic washing machine automatically executes a washing process, a first rinsing process, a second rinsing process, and a final dehydration process in this order. The dewatering process is performed as an intermediate dehydrating process at the beginning of the first and second rinsing processes, and after draining water and resetting the liquid level switch 27, the washing tub 3 and the rotary blade 6 are moved in the same direction at the same time. It consists of dehydration that is rotated at high speed.

間欠的に反転する。そして、この間欠反転による
洗いを設定時間中繰返す。 First, the washing process starts with water supply, and when the liquid level switch 27 trips, the water supply is stopped and the rotary blades 6 are stopped for about 1 second and rotated intermittently, alternating left and right for about 2 seconds. Then, this washing by intermittent reversal is repeated for a set time.
次の第1すすぎ行程は中間脱水から開始する。
そして、この後に給水し、回転翼6を洗い行程と

Then, by supplying water and intermittently reversing the rotor blade 6 in the same reversal cycle as the washing process,
Execute water injection rinsing for the set time while continuing to rinse or water supply. The next second rinse step is the first
Since this process is exactly the same as the rinsing process, the explanation will be omitted.
最後に、最終の脱水行程を実行して全自動運転
が終了する。 Finally, the final dehydration process is executed to complete the fully automatic operation.
ここで、上記3回の脱水行程では、排水の開始

をリセツトまでの時間より短くしているのは、水
位が非常に下つた時に回転翼6を回転させると洗
濯物を回転力により損傷する恐れがあるからであ
る。 Here, in the above three dehydration processes, if the "loose operation" is started at the same time as the start of draining, and the time until the liquid level switch 27 is reset is set to 30 to 40 seconds, then the drain and "loose operation" are performed for only 20 to 30 seconds. "Driving" is also carried out. This "loosening operation" is to intermittently rotate or reverse the rotor blade 6 one rotation or less/one rotation time. In this embodiment, a reversal cycle is repeatedly executed in which left and right rotations are alternately performed at a time interval (T po ) and a pause time (T pff ) is interposed between rotations. For example, T po =0.1
~0.3 seconds, T pff =0.2 seconds. In addition, "loose driving"
The reason why is made shorter than the time until reset is that if the rotor blades 6 are rotated when the water level is very low, there is a risk that the laundry may be damaged by the rotational force.
かくして、この「ほぐし運転」では洗い(すす

していく。また、揺動中に、洗濯中の糸くず等は
分散され、流出する排水中に混合して排出され
る。更に、排水時間は回転翼6が少しでも回転し
ていて水の抜けが良いので、短くなる。 Thus, in this "loosening operation", the twisted and hardened laundry is shaken little by little at the end of the washing (rinsing) process, and the laundry is flattened horizontally. At the beginning of drainage, the water level is high, so the relatively heavy laundry that has sunk near the rotor blade 6 is swayed, but as the water level falls, the oscillating force is better transmitted and dispersed horizontally. Power becomes stronger. The shaking force gradually acts stronger on small items and relatively light laundry items that tend to float, dispersing them horizontally and stacking them, and some of them also get into the laundry at the bottom. In this way, the laundry is piled up evenly around the entire circumference of the tub 3, reducing unbalanced loads. Further, during the shaking, lint and the like during washing are dispersed, mixed with the draining water, and discharged. Furthermore, the water draining time is shortened because the rotary blade 6 rotates even a little and the water drains easily.
このような「ほぐし運転」が終了してしばらく
すると、液面スイツチ27がリセツトし、このリ
セツト信号によりマイコン20は槽3及び回転翼
6を高速で右回転させ、遠心脱水を実行せしめ
る。 Shortly after such "loosening operation" is completed, the liquid level switch 27 is reset, and in response to this reset signal, the microcomputer 20 rotates the tank 3 and the rotary blade 6 clockwise at high speed to execute centrifugal dehydration.

3への給水々との関係で決めてあり、この場合は
低水位なので、短く10秒間としている。こうし
て、排水が進んで、液面スイツチ27がリセツト
すると、遠心脱水が再開される。 Due to the reduction in the unbalanced load, the occurrence of abnormal vibrations during the dewatering process is almost eliminated, but if abnormal vibrations should occur, the safety switch 28 detects this and inputs a detection signal to the microcomputer 20. Then, the microcomputer 20 causes the unbalance automatic correction program shown in FIG. 4 to be executed. That is, the first and second times the safety switch 28 is activated (OFF) due to abnormal vibration, the water supply valve 18 is opened each time to supply water to the washing tub 3 to a low water level, and the above-mentioned "relaxation operation" is performed.
Execute for approximately 30 seconds while the water level is maintained. After this, drainage starts, but it is a "loose operation".
Continue for another 10 seconds while the water level gradually decreases. The duration of this operation during drainage is determined in relation to the water supply to the washing tub 3, and in this case, since the water level is low, it is set to 10 seconds. In this way, when the drainage progresses and the liquid level switch 27 is reset, centrifugal dehydration is restarted.
一度遠心力を受けた洗濯物は槽3内の周側面に
偏り、且つ上下方向に長くなり、ほぐしにくい。
しかし、このプログラムではこれを平たくならす
必要があるので、「ほぐし運転」は排水の前から
長時間実行されている。特に再度含水すると共に

き易くなり、運転中に偏りが無くなつてくる。そ
して、この後の排水時の併用運転では上述同様に
洗濯物は平たく略均一に積まれて偏荷重を減少し
ていくのである。 Once the laundry is subjected to centrifugal force, it is biased toward the peripheral side of the tub 3 and becomes long in the vertical direction, making it difficult to unravel.
However, in this program, it is necessary to flatten the water, so the "loosening operation" is executed for a long time even before the water is drained. In particular, if the laundry is re-hydrated and operated with some buoyancy, the laundry will move more easily and will not be biased during operation. Then, in the subsequent combined operation during drainage, the laundry is piled up flat and substantially uniformly, reducing the unbalanced load, as described above.
尚、異常振動が修正できずに全スイツチ28が
3回も作動(OFF)すると、脱水動作は中断し、

れる。 In addition, if the abnormal vibration cannot be corrected and all switches 28 are activated (OFF) three times, the dehydration operation will be interrupted.
The buzzer 32 sounds intermittently to notify the user of an abnormality. This suspended state is canceled by a predetermined operation (operation of the stop key 25, etc.), and the operation is resumed by a subsequent operation of the start key 24.

ことができる。 By suppressing abnormal vibrations in the tub 3 and performing post-vibration processing in this way, the automation rate of washing is improved, washing time is no longer extended, and the spin speed is maintained to increase spin drying efficiency. By shortening the distance between the frame 1 and the outer tank 2, it is possible to reduce the size and increase the capacity.

用できる全自動洗濯機を提供できるものである。(g) Effects of the invention According to the invention, during the unbalance automatic correction program, the laundry that is clumped toward the circumference due to centrifugal force is first broken up by shaking it in water where it is easy to move. During drainage, the rocking force is gradually and strongly transmitted to all the objects, including small objects, and distributed evenly, and by repeating this, it is possible to make the objects approximately uniform in the horizontal direction and reduce unbalanced loads. Therefore, it is possible to reliably eliminate the imbalance after abnormal vibrations, so that it is possible to provide a fully automatic washing machine that can be used with peace of mind without stopping the spin-drying operation.
