Now, when an operation start command for the dehydration side is input from the operation unit input circuit 15 and a water supply command for the dehydration side water supply valve 10 is generated, the water supply control of the flowchart shown in FIG. 3 is performed. First, as you can see from steps P 1 to P 3 ,
If the water supply command is for the automatic dehydration rinsing process, the dehydration side water supply command flag E is set to "1", and if not (for the single dehydration rinsing process), the dehydration side water supply command flag F is set to " 1 ”. Then, in the next step P 4, wash-side water supply operation flag AA, BB, CC, either DD is determined whether or not "1", i.e. washing step, because rinsing cycle, overflow rinsing cycle, vessel In any of the washing steps, it is judged whether or not the wash side water supply valve 9 is opened (whether or not the water supply operation is being performed), and if the water supply valve 9 is not in the open state (wash side flags AA, BB, CC, if DD are both "0"), the step P 5 in the dehydration side water supply operation flag EE, FF dehydration side water supply command flag E, depending on the F is "1", and dehydration side at step P 6 Open the water supply valve 10. The opening operation of the dehydration side water supply valve 10 is performed in a predetermined time. During the opening operation of the dehydration side water supply valve 10, although not shown in FIG. 3, the dehydration motor 8 is intermittently driven to perform dehydration rinse. Then, the dehydration-side water supply valve 10 is shifted to Step P 8 through step P 7 when closed after a predetermined time, the flag E, F, EE, the FF as "0", the opening control of the dewatering side water supply valve 10 To finish.

When an operation start command is input for the wash side and a water supply command is issued to the wash side water supply valve 9, the water supply control of the flowchart shown in FIG. 4 is performed. First, as seen from step S 1 to step S 7, the water supply instruction wash step,
Judging whether it is a trial rinsing process, an overflow rinsing process, or a tank cleaning process, and the washing side water supply command flags A, B, C, D are selectively set to "1" according to each process.
And In the next step S 8, the dehydration-side water supply operation flag E
It is judged whether E or FF is "1", that is, the water supply valve is used in either the automatic dehydration rinsing stroke or the single dehydration stroke.
10 it is determined whether it is open, if the water supply-side water supply valve 10 is not in the open state (flag EE, both FF is "0"), in step S 9, wash-side water supply operation flag AA , BB,
CC and DD are selectively set to "1" according to the wash-side water supply command flags A, B, C, and D. Then, washing-side water supply valve at Step S 10 9
Open up. The opening operation of the wash side water supply valve 9 is executed until the set water supply amount is reached or in a predetermined time. During this run, the step S 11, dehydration-side water supply flag E As can be seen from the step S 12, F is whether it is set to "1" (whether dehydrated side water supply command occurs) to determine , Each flag E,
F is remains both a "0" state, if it is closed washing side water supply valve 9 (determined in step S 13), in step S 14, collectively the flags to D, the AA~DD "0 After that, the water supply control of the wash side water supply valve 9 is terminated.

経ステップS10で洗い側給水弁9が開放される。Next, when the water supply command is input to the wash side water supply valve 9, and the dehydration side water supply valve 10 is already in the water supply operation, as shown in step P 5 of FIG. since the water supply operation flag EE, either FF is "1", the dehydration-side water supply operation flag EE during the determination in step S 8 of FIG. 4, any of the FF is determined as "1". Therefore, the water supply control for the wash side water supply valve 9 is performed in this step S 8
It becomes a standby state. That is, in the situation where the water supply operation of the dehydration side water supply valve 10 precedes the water supply command to the wash side water supply valve 9, the water supply operation of the dehydration side water supply valve 10 has priority as shown in the priority order shown in FIG. The water supply operation of the wash side water supply valve 9 is prohibited during the execution. In this case, when the dehydration side water supply valve 10 finishes the water supply operation, step P 8 in FIG.
, The dehydration side water supply operation flag EE, FF is "0".
Therefore, in step S 8 in FIG. 4, the flag EE, FF is set.
If any of the above is judged to be “0”, the washing side water supply valve 9
A water supply standby state release of the control, and wash-side water supply valve 9 is opened in step S 10 through step S 9.
