Description of the Related Art At present, a washing and dewatering tub, a motor for rotating the washing and dewatering tub, and a rotation speed detecting means for detecting a rotation speed of the washing and dewatering tub are provided. Having a plurality of set rotation speeds in the dehydration process, turning on the motor until the set rotation speed is reached, and if the washing and dewatering tub has reached the set rotation speed, Repeat the set time on-off, so as to continuously turn on the motor until reaching the next set speed,
There is a control method that repeats on-off for each set time every time the set number of revolutions is reached. The above control reduces the contact of the outer tub with the outer frame and the shortage of the dewatering rate in the intermittent dewatering when there is a large amount of uneven laundry, and reduces the occurrence of detergent foaming in the dewatering process after washing. This improves the rinsing performance.

やすい。In the method of controlling a fully automatic washing machine as described above, a motor torque is instantaneously applied when the motor is turned on, so that abnormal noise is likely to be generated. In particular, when the amount of laundry is small and the spinning speed of the spin-drying tub is low, abnormal noise is likely to occur because the rotational inertia of the spinning tub is small.

Control means for controlling the rotation speed of the washing and dewatering tub, having a plurality of set rotation speeds in a dehydration process, and continuously turning on the motor until the set rotation speed is reached; When the set rotation speed is reached, the set time is repeatedly turned on and off, and then the motor is continuously turned on until the next set rotation speed is reached.

Ｔ2 の信号の変化から布質の判定を行う。FIG. 5 shows a circuit of the cloth amount / cloth sensor 37 for detecting the cloth amount / cloth. In the laundry amount detection control, first, appropriate clothing is put into the washing and dewatering tub 5, the power switch button 29 is pressed, and the start button 33 is pressed, whereby the motor 8 is operated. The operation of the motor 8 is performed by sending signals alternately to the gates of the triacs 37a and 37b as required by a command from the central processing circuit 34, so that the motor 8 rotates forward and backward. From the forward / reverse rotation of the motor 8, the clothes are moved by rotating the stirring blade 6 forward / reverse by the rotation transmission method shown in FIG.
At this time, the voltage between the terminals of the driving capacitor 8a of the back electromotive force generated when the motor 8 is turned off is converted into a DC rectangular wave pulse by the photo-triac coupler 38, and the inverter 3
9, the DC square wave is inverted, and the signal is processed by the central processing circuit 3.
Send to 4. By these controls, the resistance applied to the stirring blade 6 changes depending on the size of the clothes, and the degree of this change is detected to determine the amount of the clothes. After the cloth amount is determined, the cloth quality detection control is performed. With the cloth quality detection control, after performing the cloth amount detection control, the water supply electromagnetic valve 24 is energized by a signal from the controller unit,
Water is supplied into the washing and dewatering tub 5. When the water level sensor 13 detects that the water has been supplied to the specified water level, the motor 8 rotates forward and backward similarly to the cloth amount detection control, and a signal (T 1 ) of the voltage between the terminals of the driving capacitor 8 a of the generated back electromotive force is generated. To the central processing circuit 34. Next, water is supplied into the washing and dewatering tub 5 up to the water level determined by the cloth amount detection control, and when the water level sensor 13 detects that the water has been supplied to the cloth amount determination water level, the motor 8 is activated similarly to the cloth amount detection control. Reverse rotation is performed, and a signal (T 2 ) of a voltage between terminals of the driving capacitor 8 a of the generated back electromotive force is sent to the central processing circuit 34. The cloth quality is determined from the changes in the signals T 1 and T 2 .

臭，発煙の発生等の問題が生じる（洗剤発泡障害）。After the cloth amount detection control is completed, a washing process is performed. After the washing process is completed, the drain valve 15 is energized by a signal from the central processing circuit 34 to perform the drain process. When the draining process is completed, the motor 8 is energized to rotate the washing and dewatering tub 5, and the washing liquid contained in the clothes in the washing and dewatering tub 5 is taken out by the centrifugal force. At this time, if the washing and dewatering tub 5 is continuously rotated, the amount of water coming out of the washing and dewatering tub 5 becomes larger than the amount of water drained from the drain port 16.
The washing liquid collects. Since the washing liquid accumulated in the outer tub 4 is stirred by the rotating washing and dewatering tub 5, bubbles increase, and the surface tension of the foam prevents rotation of the washing and dewatering tub 5. An increase in the flowing current causes problems such as generation of an odor and smoke from the motor (detergent foaming failure).

The motor 8 is continuously energized up to the rotation speed N1 of the washing and dewatering tub 5 between a and the vibration resonance point b. When the rotation speed reaches N1, the power supply to the motor 8 is stopped for Ta seconds, and thereafter, the motor 8 is supplied again to the rotation speed N1. These series of operations are repeated for T1 seconds, and thereafter, the motor 8 is continuously energized to a rotation speed N2 higher than the vibration resonance point b.
When the rotation speed reaches N2, the energization of the motor 8 is stopped for Ta seconds, and thereafter, the motor 8 is energized again to the rotation speed N2. These series of operations are repeated for T2 seconds, and thereafter, the series of operations is repeated n times at T3 seconds at N3 and Tn seconds at Nn.

ータのオン時に発生しやすい異音を防ぐようにする。FIG. 7 is a flowchart showing the above operation. In step 51, the motor 8 is energized, and in steps 52 and 53, the motor 8 is energized until the set rotation speed N is reached while the rotation speed is detected by the rotation speed detection device 20. When the set number of revolutions N is reached, the energization of the motor 8 is stopped for Ta seconds in step 54, and the motor 8 is energized again until the set number of revolutions N is reached (steps 55, 56, 57).
These operations of steps 54 to 57 are repeated for T seconds (step 58).
Step 59 is performed until the operations of 54 to 58 are completed n times, and then the process proceeds to the next step (step 60). However, in the case of the above-described control method, abnormal torque is likely to be generated because the motor torque is instantaneously applied when the motor is turned on. In particular, when the amount of laundry is small and the spinning speed is controlled at a low speed, abnormal noise is likely to be generated because the rotational inertia of the washing and spinning tub is small. Therefore, in order to improve the above-mentioned problem, the present invention will be described with reference to FIG. 8, in which the phase control is performed when the motor is turned on, and the cut width of the phase control is set to gradually decrease as shown in FIG. The time during which the phase control is performed is set to several milliseconds. By performing the phase control, the motor torque is gradually increased, and abnormal noise that is likely to be generated when the motor is turned on is prevented.
