イクルとする反転時限を繰り返し行うものである。Conventionally, a control device for a washing machine of this type has been shown in FIG.
There was a water flow cycle as shown in FIG. That is,
The water flow of the large clothing is a repetition of a reversal time period in which the right, right, left, left, right, and left rotations constitute one cycle.

た。However, in the above-mentioned conventional control device for a washing machine, the reversal time is a water flow suitable for washing a blanket of a certain size or weight. It is not suitable for washing. In other words, since the water flow of large clothing is a single water level, water flow suitable for blankets of a certain thickness and weight,
Washing a small, thin and light blanket with this water current may cause the water current in the left and right direction to be too strong, damaging the blanket, and washing a towelet etc. will cause the water flow to be too strong and rotate in a lump state, resulting in cleaning performance. And the washing water splashes from the washing tub and wets the floor surface.

ことができる。As shown in FIG. 1, the control means 7 is composed of various electronic circuits including a microcomputer.
An instruction from an operation key (not shown), a signal from the lid switch 8, and a signal from the water level detecting means 9 are taken in, and the motor 5, the bidirectional thyristors 10a, 10b, 10c, and 10d are used.
It controls the energization of the drain valve magnet 11 and the water supply valve 12. The capacitor voltage detection circuit 13 detects a load amount, and the phase-advancing capacitor 1 of the motor 5
4 is detected and the output is input to the control means 7. The water flow selection means 15 is provided for the capacitor voltage detection circuit 1
3 to select one of a plurality of water flows having different reversal times stored in the control means 7 and to select a water level and a water flow according to the type of load in a large course for washing large clothes. I am trying to do it. The control means 7 determines the load in the washing tub 1 based on the output of the capacitor voltage detecting circuit 13 based on the decay rate of the back electromotive voltage of the motor 5 during the rest period after the motor 5 is energized for a required time. Generally, the terminal voltage of the capacitor 14 has a correlation with the number of revolutions of the motor 5, and turns on the bidirectional thyristors 10a and 10b.
Thereafter, the terminal voltage of the capacitor 14 attenuates in accordance with the rotation speed of the motor 5 during a rest period before the rotation is reversed. That is, during the idle period of the normal rotation and the reverse rotation of the motor 5, the bidirectional thyristors 10a and 10b are turned on and the terminal voltage of the capacitor 14 becomes 0, but the motor 5 is rotated before the idle period. , The motor 5 continues to rotate by inertia, and induces a back electromotive voltage in the main coil and the auxiliary coil, and the back electromotive voltage decreases as the rotation speed decreases,
Waveforms as shown in FIGS. 5A and 5B are obtained. (A) shows the case where the load is small and the amount of decrease in the number of revolutions of the motor 5 is small, and (b) shows the case where the amount of load is large and the number of revolutions of the motor 5 rapidly decreases. As described above, the load amount can be determined by measuring the change rate of the capacitor voltage or the damping rate such as the number of voltage waveforms for the capacitor voltage decay time (T1a, T1b).

FIG. 3 shows a case where a blanket other than the blanket is washed. FIG. 4 shows a case where a light tuft blanket or the like is inserted into the blanket washing net 6. Each case is shown for washing. Thick and heavy Meyer blankets will have a higher water content when filled to the middle water level, and will have a larger load, reducing the number of voltage waveforms.In the case of light tuft blankets and other non-blanket towelettes, supply water to the middle water level. However, since the water content is not small, the floating load on the water surface is small, and the number of voltage waveforms is large. As described above, since the load amount is detected with the water supply amount at the middle water level, the magnitude of the load amount of a heavy blanket and a light blanket or a towelet other than the blanket can be determined by the number of voltage waveforms. Therefore, a determination reference value for the number of capacitor voltage waveforms is set, and a heavy blanket or a light blanket and a load other than the blanket can be determined based on the determination reference value and the number of waveforms.

0 times, agitation of reversal is performed, and O
The number of capacitor terminal voltage waveforms after the FF is measured, and if it is equal to or greater than the determination reference value, it is determined that the weight is a heavy blanket, and if it is less than the determination reference value, it is determined that the weight is a light blanket or a towelet other than the blanket. After this determination, as shown in FIG. 2 to FIG. 4, only the heavy blanket is re-supplied with water and set to a high water level, and the light blanket and the towelet other than the blanket are kept at the medium water level. In addition, as shown in FIG. 8, the water flow is divided into two and set. In other words, the high water level water flow for heavy blankets is a reversal of the reversal time period with one cycle of right, right, left, left, right, and left rotations. The medium water level water flow for towelets other than light blankets and blankets rotates left and right. If it is too strong in the direction, when the blanket is washed, the damage prevention film 6a will fall down and the blanket washing net 6 will be directly
Because the blanket is damaged because it comes into contact with
The ON-OFF period of the inversion period, in which the rotation of the right, left, left, right, and left is one cycle, is shorter than that of the blanket, and the water flow is weakened in the left-right rotation direction. As in the case of the water flow 2, a simple left-right rotation inversion time period is used. In the case of this water current, since the left and right rotation of the light blanket is weakened, the damage prevention film 6a does not fall down, and the blanket washing net 6 does not directly contact the stirring blade 3, so that the damage to the blanket is reduced.

Even when washing a towelet other than the blanket, even if the laundry is washed on a large course. ,
It prevents dripping of washing water on the floor and the like and a decrease in the washing effect, and the amount of water used matches the capacity of the clothes because washing is performed at the middle water level.Washing water dripping on the floor or rotating too much The washing effect is not reduced, and the washing water can be saved.

In this case, the load is determined. The larger the amount, the longer the decay time, and the smaller the load, the shorter the decay time. The rate of change of the voltage is small when the load is large, and is large when the load is small. In addition, instead of detecting the capacitor voltage, the current value of the capacitor may be detected.
What is necessary is just to detect a current value.

By doing so, in a washing course for large clothing, by setting the water level and the water flow suitable for the type of clothing, washing can be performed without impairing the washing effect even with blankets and laundry other than blankets having different thicknesses and weights. The washing water can be prevented from scattering on the floor, and the practical value is remarkable.
