Description of the Related Art Conventionally, as disclosed in Japanese Patent Publication No. 3-11240, this type of fully automatic washing machine has been used to check whether the rotation speed of a dewatering tub during intermediate dewatering has risen to a predetermined rotation speed within a predetermined time. If it does not detect, and it does not reach the predetermined number of revolutions, it is determined that the dewatering tank has fallen into a bubble-restricted state, the intermediate dewatering process is stopped, the process moves to the next rinsing process, and the foam is diffused by supplying water. Eliminates bubble restraint. Then, the turbidity change of the water is optically detected at the time of rinsing, the rinsing condition is automatically determined, and the rinsing step is completed. In a fully automatic washing machine that controls the time of the rinsing step, the intermediate dehydration is stopped halfway, and the process shifts to the next rinsing step.

0秒以内に脱水槽2の回転数は高速回転迄立ち上がる。The rotation of the motor 12 is transmitted to a mechanical box 17 by a motor pulley 14, a pulley belt 15, and a center pulley 16. Then, only the pulsator 3 rotates during the washing / rinsing process, and the pulsator 3 and the dewatering tub 2 rotate in the same direction during the dewatering process by the action of the clutch mechanism built in the mechanical box 17. That is, when the motor 12 is stopped at the end of the washing process, the pulsator 3 stops. After the motor stops, the counter of the microcomputer 22 is set to M = 0. Then, an ON signal is output to the drain valve control unit 9, the drain valve 8 is opened, and the water in the tank is drained through the drain hose 7. The water level detector 11 detects completion of drainage, and the signal is sent to the sequence control unit 2.
2, an ON signal to the motor control unit 13 is input,
The motor 12 is driven. The rotation of the motor 12 is linked to the rotation of the dewatering tank 2 and the pulsator 3 from the center pulley 16 by the function of the clutch mechanism built in the mechanical box 17. That is, the dewatering tank 2 rotates and the centrifugal force causes
Intermediate dehydration starts, squeezing out the water contained in the laundry. At the same time, the sequence control unit 22 starts counting the intermediate dewatering time t. Normally, 1 when no bubble constraint occurs
Within 0 seconds, the rotation speed of the dewatering tub 2 rises up to high speed rotation.

FIG. 4 shows the relationship between the elapsed time and the number of rotations. Therefore, when the intermediate dewatering time t reaches the predetermined time t 1 ,
From the output of the rotation number detecting unit 19 detects the rotational speed N of the dewatering tank 2, if the comparison between the predetermined rotational speed N 1, can be detection of the presence or absence of the bubble restraint.

のための給水を行う。The number of rotations of the motor is n 1 , the motor pulley 14
Assuming that the pulley ratio of the center pulley 16 is P 1 and the number of magnetic poles of the pulse generator 18 is P 2 , the center pulley 1
The rotation number 6 is represented by n 1 × P 1 , and the rotation number N of the dewatering tank 2 is also represented by N = n 1 × P 1 . Since the output pulse number P 3 of the pulse generator 18 is equal to the number of rotations of the center pulley 16 multiplied by P 2 , P 3 = n 1 × P 1 × P 2 = N × P 2 and the output pulse of the pulse generator 18 rotational speed of the relationship between the number and dewatering tank 2, if P 3 = N × P 2 normal rotational speed N of the dehydrating tub 2 represented by rises to one or more predetermined rotational speed N, as a predetermined intermediate dehydration continue to intermediate dewatering until time t 2 comes, it stops driving the motor 12. The spin-drying tub 2 that has been rotating at a high speed rotates by inertia. The sequence control unit 22 counts the inertial dehydration time t ′, and when a predetermined time t 3 is reached, outputs an OFF signal to the drain valve control unit 9 to close the drain valve 8, and the brake mechanism built in the mechanical box 17 uses The dewatering tank 2 is stopped. Then, an ON signal is output to the water supply valve control unit 6 to open the water supply valve 5, and water is supplied for the first rinse.

Since the rotation of the dewatering tank 2 is very slow, almost no inertial rotation, stops driving the motor 12 to close the drain valve 8 if the above as well as inertial dewatering time t '= t 3, the brake mechanism To stop the dewatering tank 2.

M counts the number of shifts to the foam constraint correction process, and if the preset number of shifts to the foam constraint correction process M 1 (M 1 = 2 in the embodiment) is M <M 1 , the water supply valve 5 is opened. Supply water for the first rinse.

In the dehydration tub 2 through a, it is dissolved and diffused in water while returning. When the water supply to a predetermined level of foam diffusion process, operating t 6 hours foam diffusion process (basically set the performs the same motor driving the washing step bubbles in the water flow easily diffused in water).

After correcting the deviation of the cloth, the process returns to the original main program, and the rinse I process is repeated. Then, when performing the intermediate dehydrating again, if the rotational speed N is N ≧ N 1, it stopped for a predetermined time t 2 has elapsed after the motor 12, by closing the drain valve 8, along the following sequential main program performs the water supply Drive.

The dehydration process of the main program is stopped, and the process is shifted to a separately provided process.
Stop, close the drain valve, supply water, rinse,
In a washing machine provided with a control method so as to shift to the cloth deviation correction step and return to the dehydration step of the main program again, the unbalance correction step may be used for the foam restriction correction step. In this case, processing can be performed by the same program in the microcomputer 22, which is advantageous in terms of memory capacity and can be inexpensive.
