する。2. Description of the Related Art Conventionally, in a fully-automatic washing machine, as a method of preventing noise and deterioration of durability when dehydration operation is performed with uneven cloth, it is automatically returned to the rinsing process once abnormal vibration is detected. Therefore, the uneven process of the laundry was eliminated, and the corrective process of performing dehydration was subsequently performed. However, since such a correction process requires a large amount of water and is economically inefficient, a fully automatic washing machine having improved this is proposed, which will be described with reference to FIG.

都度レバーで検知して検知信号を出力する。In FIG. 8, reference numeral 1 is a machine frame, 2 is an operating portion provided in the upper rear portion of the machine frame 1, 3 is an outer tub which is suspended within the machine frame 1 by a suspension rod or the like for vibration isolation. Is a washing / dewatering tub rotatably mounted in the outer tub 3, 5 is a dehydration hole, and 6 is a rotary blade. Reference numeral 17 denotes a vibration detection switch provided in the operation unit 2. A detection lever 18 is vertically provided between the machine frame 1 and the outer tub 3 to detect an abnormality in the outer tub 3 caused by rotation of the dehydration tub 4 during dehydration. Each time the vibration is detected by the lever, a detection signal is output.

て上述の動作を繰返す。When the outer tub 3 abnormally vibrates during the spin-drying process due to uneven distribution of the cloth (laundry to be washed), the vibration detection switch 17 detects the abnormal vibration and outputs a detection signal.
On the other hand, the microcomputer counts the number of arrivals of the detection signal, and if, for example, five signals are input, it is determined that the abnormal vibration state exists. When it is determined that the microcomputer is in an abnormal vibration state, the dehydration operation is continued, or the motor 7 is temporarily stopped, and then the triac is triggered every 1 to 2 Hz to intermittently rotate the motor 7. Rotation speed of dehydration tank 4 is 30
The dehydration operation is continued with a low rotation speed of about 0 rpm. In addition, the vibration detection signal is continuously input to the microcomputer, and when the water is drained and the detection signal does not arrive within a certain period of time, the intermittent rotation is stopped and switched to continuous rotation. Then, the above operation is repeated.

生じる。Recently, it has been desired that the fully automatic washing machine has a large capacity and space saving, that is, one in which the space of each part is designed to be small while maintaining the washing capacity.
Therefore, in the fully automatic washing machine shown in FIG. 8 as a conventional example,
Even after the occurrence of abnormal vibration during the dehydration operation, water is not injected to correct the unevenness of the cloth and only the dehydration rotation speed is lowered to operate, so that a sufficient dehydration or rinse state cannot be obtained. Alternatively, even if the washing machine is operated by increasing the spin-drying speed without water injection, not only the vibration of the washing machine main body is large and noisy, but also it is necessary to have a strength capable of withstanding the uneven centrifugal force of the cloth.

By washing or rotating to the left or right at a cycle shorter than that at the time of rinsing, the state of the cloth is made uniform by the small movements of the rotary blades 6. After performing this operation for a certain period of time, the drainage electromagnetic valve 10 is opened in step S6, the clutch mechanism is connected in conjunction with it, and the motor 7 is energized only in the dehydration rotation direction (motor 7 right rotation) in step S7. I do.

In step S8, the shake is quantitatively read there by the hall element 17, and is discriminated by the microcomputer 22 together with the total load amount and the water level data. If it is less than the experimentally determined specified value, the process proceeds to step S9. Then, the energization of the motor 7 is temporarily stopped, and after the water level detection switch 13 detects the reset in step S10, the process goes to the dehydration step, and the motor 7 is energized again to perform the dehydration operation.

In step S11, it is determined whether the number of corrections N, which indicates the number of times the bias correction process has been performed, is greater than 5. When the number of corrections N is larger than 5,
After shifting to step S12, the user is informed by the buzzer 27 that the bias cannot be corrected, and the user removes the cause of the uneven cloth condition. Then, in step 13, the user presses a predetermined operation key. Stop working until. When the operation key is pressed in step S13, the process returns to step S10, and if the water level is the reset point in step S10, the process proceeds to the dehydration process.

In step S14, in order to update the correction number N, it is stored in the storage unit provided in the microcomputer 22 as a value obtained by adding 1 to the already stored correction number N. After updating the value of the correction number N in step S14, the process returns to step S4 and bias correction is executed again. Although it is determined in step S11 whether or not the value of the correction number N is larger than 5, this is not limited to 5 times, and may be an appropriate value obtained experimentally.

In the third embodiment, after the cloth state correcting operation shown in the first embodiment is performed, it is determined in step S8 whether the amplitude of the outer tub is equal to or less than a specified value in order to determine the cloth state again. To judge. In step S8, when it is determined that the amplitude of the outer tub is not less than the specified value, that is, the state of the cloth is non-uniform, the process proceeds to step S15.

Then, it is considered that the previous correction operation is inappropriate for the state of the cloth, and a different force is applied thereto. Therefore, in step S17, the motor left / right reversal time T1 is expressed as Change according to. T1 = T1 + N · dT1 (Equation 1) Note that T1 on the right side of the above Equation 1 is a motor left-right reversal time that has already been set, and a predetermined initial value is set at the start of operation. Further, dT1 is a correction value of the motor left-right reversal time.

T1 = T1 + N · dT2 (Equation 2) Note that T2 on the right side of the above Equation 2 is the already set motor right operation time, and a predetermined initial value is set at the start of operation. Further, dT2 is a correction value for the motor right operation time.

The number of rotations in the right direction may be changed by a method of continuously rotating rightward twice or three times. In addition, when the correction number N reaches a predetermined number, it may be determined that the bias correction is impossible and a buzzer may be sounded to notify the user.

置も行なってもよい。In the above embodiment, the condition of the cloth is judged from the data such as the load and the water level based on various experimental data, and the vibration is good even when the dehydration operation is performed, and the dehydration tank 4 and the outer tank 3 or the outer tank are vibrated. 3 is transferred to the dehydration operation on the assumption that the machine frame 1 is not in contact, but the displacement of the outer tub is read during the actual dehydration operation, and at the same time, the rotation sensor 29 provided in the motor 7 for the rotation speed of dehydration. If the vibration value is large based on the correlation, or if it is determined that the displacement is considered to cause deformation and contact due to the extreme centrifugal force from the correlation, the motor 7 is intermittently energized to perform dehydration rotation. In addition to decreasing the number, treatment such as prolonging the dehydration time may be carried out if necessary.
