Based on the input from the switch input section 13, it is determined whether or not the start switch has been operated (step S1). If it is determined that the start switch has been operated, the water supply valve 10 is then driven open to detect the amount of laundry. Supply water up to a specified water level suitable for
Step S2), then, by driving the motor 6, the drive mechanism 7 rotates the stirring body 5 in forward and reverse directions, and starts an operation for detecting the load amount (Step S3). For example, as shown in FIG. 5, the forward and reverse rotation of the agitator 5 is performed by energizing the motor 6 in the forward direction for 0.6 seconds, pausing for 1.0 seconds, and then turning the motor 6 in the reverse direction.

Furthermore, if it is determined in step S5 that the area is not A, it is determined that the area is B, so here, the phase difference detection signal (load amount detection signal) by the phase difference detection device 14 in the B area is determined. The input is taken in the same way as described above (step S8), and the integration of the input is also done in the same way as described above (step S9). Then, the input is integrated until it is determined whether or not five forward rotations have been performed (step S10), and then the operation for detecting this load amount is ended (step S10).

きな値となって現われる。FIG. 6(c) shows changes in the input input as described above, and shows when the amount of laundry being stirred by the agitator 5 is large and when it is small. Differences X and Y in comparison with the state of only water, respectively, appear as a difference in which the difference X is large when the amount of laundry is large in the B section of the unit driving time of the agitator 5, On the other hand, when the amount of laundry is small, the difference Y appears as a larger value in the A section than in the B section.

構かかるかかるからである。This is because when the amount of laundry is large, the resistance from the laundry is applied to the motor 6 sufficiently until the end of the unit drive time, whereas when the amount of laundry is small, the resistance from the laundry is applied to the motor 6 until the end of the unit driving time. At the end of the unit drive time, there is almost no resistance from the laundry to the motor 6. On the other hand, at the beginning of the unit drive time, the laundry is carried away by the water flow. This is because the laundry does not reach the point where it flows, and the motor 6 is subjected to considerable resistance from the laundry.

2). As a result, if it is determined that the amount of laundry is "large", the washing water level is set to "high" (step S13),
After water is supplied to the set water level (step S14), the motor 6 is driven in earnest to begin washing in which the agitator 5 is rotated in full forward and reverse directions by the drive mechanism 7 (step S15).

If it is determined that the amount of laundry is not "large", then it is determined whether the amount of laundry is "medium" based on the detection integration result in section A (step S16). As a result, if the amount of laundry is determined to be "medium", the washing water level is set to "medium" (

行なうことができる。As described above, in this configuration, the motor 6
The amount of laundry is determined based on the detection result by the phase difference detection device 14 in section B of section A, which is the first half of the unit drive time, and section B, which is the second half of the unit drive time. When it is determined that the amount of laundry is small, such as "medium" or "small," the amount of laundry is further determined based on the detection result by the phase difference detection device 14 in section A. Since the timing at which the appropriate resistance is applied is different, the amount of laundry can be judged as accurately as possible, not only when the amount of laundry is large, but also when it is small, so subsequent operations can be adjusted accordingly. This can be done with appropriate content.
