Embodiment six
The concrete steps of control method for washing machine described in the present embodiment are as follows:
Washing
After the selected good washing procedure needed also selectes flocculation treatment function, press startup button, washing machine inflow is to the inflow of setting, and driven by motor inner core rotates, and starts washing.
Flocculation
After washing terminates, first row water pump is opened, and be drained into by the washings of dirt to designated water level in flocculation container, master control borad adds a certain amount of flocculate by flocculant dispenser according to the program of setting in flocculation container.Agitator arm work certain hour t1, in flocculation container, water forms current under the drive of agitator arm, makes water in flocculation container and flocculant rapid solution, reaction; After after standing a period of time t2, dirt contained in washings can be condensed into the flocculate that bulky grain forms and swim in container by flocculant, and bottom is then the clean clear water after process.
Filter
After flocculation terminates, second row water pump is opened, and the clear water in flocculation container can flow in filtering container, and the screen pack in filtering container can stop flocculate and dirt offline, and clear water then can be squeezed in tube filled with water again to be continued for rinsing.
Circulation
Repeat above-mentioned flocculation and filtration process until rinsing terminates.
Cleaning and draining
After circular treatment water terminates, water in tube filled with water is drained into again in flocculation container, open second row water pump simultaneously and part water is entered into cleaned filter screen in filtering container, finally open blowoff valve and the dirt on the dirt of flocculation, screen pack, line bits are discharged to outside washing machine together with water
After rinsing terminates, the water in tube filled with water all enters flocculation treatment unit and filter element as flushing water, and cleans it, finally drains into outside washing machine.
Embodiment seven
The present invention, according to the washings turbidity detected after washing, judges whether to need to carry out flocculation treatment, when turbidity is higher, then directly can discharge completely, again enter clear water rinsing, cycling use of water rinsing of flocculating again after first time rinsing; Or according to the scope of turbidity, discharge a certain proportion of washings, then enter running water and reduce turbidity, then cycling use of water rinsing of flocculating.
Washing machine of the present invention also comprises detergent dispenser, and detergent dispenser is prior art, is preferably the structure utilizing water inlet negative pressure extracting washing agent to throw in; Flocculant dispenser of the present invention is for automatically to throw in structure.
Embodiment in above-described embodiment can combine further or replace; and embodiment is only be described the preferred embodiments of the present invention; not the spirit and scope of the present invention are limited; under the prerequisite not departing from design philosophy of the present invention; the various changes and modifications that in this area, professional and technical personnel makes technical scheme of the present invention, all belong to protection scope of the present invention.
