Description
Technical field
The present invention relates to washing machine field, specifically circulating water saving washer, especially a kind of control of flocculation washing machine
Method and washing machine.
Background technology
With the raising of people's living standard, washing machine has become one of main household electrical appliances of people's daily life, laundry
The laundry processes of machine mainly include washing, rinsing, dry several stages, in washing stage washing machine inflow and detergent to medicated clothing
Washed, in order to rinse the detergent of spot and residual after entering rinse stage, needed more into more water or execution
Rinsing times rinse to medicated clothing, and this certainly will expend substantial amounts of water resource, even the roller washing machine of water-saving, in order to rinse
Medicated clothing is also required to rinsing at least twice, the tap water of this process more than 30l at least to be consumed.Sometimes the spot on medicated clothing is less
Or the detergent of input is less, twice with regard to rinsed clean, but because user have selected 3 rinsings, certainly will may will also result in
The general basic water consumption of washings twice of the automatic washing machine of the waste of water resource, such as 6kg is at 100 liters about.How to exist
Water and electric saving, always one of consumer's focus of attention can be accomplished while clean clothes.
Not yet there are the matching used Water warfare of washing machine and recycling device, even so-called band so far
There is the washing machine of water-saving function, typically in the side position of washing machine, storage tank is installed, water filling and draining, general energy are carried out using water pump
Enough water fillings, rinse 3 times, play water-saving function.But the water after washing can not preserve, make this body structure of washing machine multiple simultaneously
Miscellaneous, huge, it is unfavorable for transport, recycling etc..Due to the restriction of the aspects such as volume, structure and motility, have impact on laundry
The giving full play to of machine original function and water-saving box function itself.In order to preferably save water on the basis of existing laundry mode
Resource, a lot of producers have put into substantial amounts of research and development.
Existing washing machine carries recirculated water function, and it functions only as filtering line bits, and washing uniformly or is added plus ozone, weight
The effects such as metal ion sterilization.Water consumption cannot be improved, and there is no basic raising to cleaning.
The recycling of laundry water, through consulting Patents documents, " the washing machine of such as Application No. 200810072420.5
Recycling water saving device ", is to input laundry water in one water drum, carries out purified treatment.This invention is washed for first pass
Clothing water does not carry out purifying directly draining, for second, third time rinsing water carry out purified treatment after, next time to be remained washes
Use during clothing.
A kind of conventional sewage water treatment method is also had to be coagulating/flocculating method for processing, it adopts flocculant to included in sewage
Dirt carries out flocculation treatment, makes the dirt in sewage be changed into flocculate and is separated from water out.Using this kind of sewage treatmentmethod, high
Effect, environmental protection, energy-conservation, with low cost.Therefore, flocculation treatment sewage is combined with washing machine, generate new recirculated water washing machine
Mode become innovation focus.
In view of this special proposition present invention.

7.3g、a3=12g；Corresponding flocculation cycle-index n is respectively n1=3, n2=6, n3=9.
That is, 11) by clothes weight, washing machine detects that program draws washings inflow l=l1=14 liter, calls correspondence to wash
Wash flocculation cycle-index n1=3 of water inflow l1, the addition a1=4g of flocculant and flocculation single inflow v1=10 liter；Logical
Cross the first liquid level sensor detection it is ensured that the washings water yield actually entering in tube filled with water is 14 liters, execution washing procedure is to washing
Wash and complete；
12) washings that in tube filled with water, set volume v1=10 rises flow in flocculation container through the first draining pump, so that flocculation is held
The height of water level of the washings in device reaches setting value；
13) throw in flocculant to set amount a1=4g in the washings flow into flocculation treatment unit；
14) washings and flocculant fully react, and the dirt in washings, under flocculant effect, is changed into flocculate, and
Washings are changed into clean water；
15) flocculate is floated to clean water upper surface；
16) clean water after flocculation automatically cleaning is processed passes back in tube filled with water；
Above-mentioned steps 12) to step 16) circulate for once washing water flocculation；Above-mentioned steps are pressed in washing machine flocculation process
12) to step 16) circulating repetition execution, the flocculation cycle-index of every circulation primary washing machine accumulates once, to flocculation circulation time
When number reaches n1=3, washing machine flocculation treatment process terminates；Wherein, described flocculation cycle-index n, is to enter as needed to contain
The inflow l of the washings in water drum determines.
Embodiment two
As shown in Figure 2 and Figure 4, there is following difference: described the concrete of cycle-index n of flocculating in the present embodiment and embodiment one
Determine that step is as follows,
1) weight according to washing medicated clothing and/or material determine, or are directly set by user, or through arranging in tube filled with water
The first liquid level sensor detection draw the corresponding inflow l of washings, made in injection tube filled with water by the first liquid level sensor
Tap water be corresponding inflow l；
2) according to corresponding inflow l, basis flocculation cycle-index n1 of corresponding washings and corresponding washing water turbidity are called
Decision content p '；
3) the turbidity value p of washings after the completion of the first turbidity transducer detection in tube filled with water is washed, by detected value p
Compare with the decision content p ' of corresponding washing water turbidity, if during p >=decision content p ', variable flocculation cycle-index n2=1；If p ＜ judges
During value p ', variable flocculation cycle-index n2=0；
4) according to flocculation cycle-index n=basis flocculation cycle-index n1+ variable flocculation cycle-index n2 of washings, obtain
Go out flocculation cycle-index n of washings.
In the present invention, washing machine is provided with different inflow l and is respectively l1, l2...ln, the different basis flocculation circulation of correspondence
The setting of washings in flocculation container is flowed in frequency n 1, the decision content p ' of washing water turbidity and each flocculation circulating treatment procedure
Volume v, corresponding n1 are respectively n11, n12...n1n；Corresponding p ' is respectively p1 ', p2 ' ... pn '；Corresponding v is respectively
v1、v2...vn.When the water level amount of described washing machine is l1, corresponding basis flocculation cycle-index is n11, corresponding washings
