Next, the control means 11 determines whether or not the time t 1 minute when the detergent is sufficiently dissolved in water has elapsed in step 20, and if not, the control proceeds to step 21.
And dissolve the detergent in water. Upon expiration of t 1 minute, the process proceeds to step 22, and inputs the initial permeability by the permeability detection means (d 0). Further, in step 23, t 2 minutes (>
t 1 ) It is determined whether or not it has elapsed. If not, at step 24, stop for 3 minutes and repeat stirring for 1 minute until t 2 minutes have elapsed. With this operation, the stain on the cloth gradually seeps into the water. When t 2 minutes have passed, the process proceeds to step 25, where the water permeability (d 1 ) is input again. The time chart of the transmittance in this stirring operation is as shown in FIG. 2. In the case of severe stains such as oil stains, the transmittance decreases at a substantially constant rate.
In the case of mud dirt, the transmittance greatly decreases at the beginning, and becomes substantially constant thereafter. Utilizing this characteristic, the control means 11 executes step 26,
T 1 and t the amount of change in permeability between 2 27 (d 0 -d 1) is less than 1V, 1V
Steps 28 and 2
The duty ratio of the agitation-stop cycle is set to 1 at 9 and 30, respectively.
Set to / 2, 1/3, 1/4. If the duty ratio set here is 1/2, as shown in FIG. 3, for example, the stop time is 2 minutes and the stirring time is 1 minute. Next, in step 31, it is determined whether or not the total time of the pre-washing has elapsed, and if not, in step 32, the duty ratio of the stirring time and the stop time set in the above steps 28, 29, and 30 is used. The stirring is repeatedly stopped.
