This step continues to judge.
S72, laundry generator terminal send out stopping and launch instruction；
S73, dispensing end detects water flow variation by water flow sensing unit 7 and whether stopping dispensing instruction is consistent, if unanimously,
Enter step S8；If inconsistent, S74 is entered step.
S74, dispensing end judge whether the maximum time for reaching detergent dispensing, if so, S8 is entered step, if it is not, then
The step is returned to continue to judge.
Throwing mechanism 6 is closed in S8, external circuit board control.
The present invention updates washing machine 20 after the external detergent throwing device of user installation, by network or after-sales staff
Driver can generate the flow cavitation result mode for exporting detergent injected volume, simple in structure, and transformation is convenient, meets
The demand of existing conventional laundry apparatus automatic detergent adding.Such as：
If weighing by clothing, know that the detergent demand of clothing is 20g, it can be regular right during water inlet
The water inlet of washing machine 20 is controlled, and such as with one second interval during water inlet, continuous cutting-off water intake valve of washing machine 5 is three times.
So on inlet pipeline 2, the water flow variation of corresponding time interval will be detected.By detecting water flow variation, outer circuits
Plate control, which is opened, is launched pump or is launched to detergent using Venturi tube.After reaching the detergent release time of needs,
Again with one second interval, continuous cutting-off water intake valve of washing machine 5 three times, in test side, after obtaining water flow variation, close launch pump or
Venturi tube terminates the dispensing to detergent.
