Description
Technical field
The present invention relates to washing machine fields, specifically the cycling use of water processing equipment and method of washing machine, especially a kind of
Washing machine cycles filter cleaning device and cleaning method.
Background technique
As the improvement of people's living standards, 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, drying several stages, in washing stage washing machine inflow and detergent to clothing
Washed, into rinse stage after in order to rinse spot and remaining detergent, need into more water or execute more
Rinsing times rinse clothing, this certainly will expend a large amount of water resource, even the roller washing machine of water-saving, in order to rinse
Clothing is also required to rinsing at least twice, this process will at least consume the tap water of 30L or more.Sometimes the spot on clothing is less
Or launch detergent it is less, may twice with regard to rinsed clean, but due to user selected 3 times rinsing, certainly will will also result in
The waste of water resource, for example, 6Kg automatic washing machine generally twice the basic water consumption of rinse water at 100 liters or so.How
It can accomplish water and electric saving while cleaning clothes, be always one of consumer's focus of attention.
There has been no the matching used Water warfare of washing machine and recycling device, even so-called bands so far
There is the washing machine of water-saving function to be filled the water and drained using water pump generally in the side of washing machine position installation water tank, general energy
Enough primary water fillings, rinse 3 times, play water-saving function.But the water after washing can not save, while keep this body structure of washing machine multiple
It is miscellaneous, huge, it is unfavorable for transport, recovery processing etc..Due to the limitation of volume, structure and flexibility etc., laundry is affected
Machine original function and water-saving box function itself give full play to.In order to preferably save water on the basis of existing laundry mode
Resource, many producers have put into a large amount of research and development.
Existing washing machine has recirculated water function, functions only as filtering line bits, and washing is uniformly or addition plus ozone, again
The effects of metal ion is sterilized.It is unable to improve water consumption, and to clean not basic raising.
Laundry water recycles, and through consulting Patents documents, such as application No. is 200810072420.5 " washing machines
Recycling water saving device " is to input laundry water in one water drum, carries out purified treatment.The invention is washed for first pass
Clothing water is directly exhausted without purification, after carrying out purified treatment for the rinsing water of second, third time, to remain to wash next time
It is used when clothing.
In the above-described techniques, " recirculating water technical " is used after rinsing Water warfare, which cannot recycle the
A time laundry water (first wash water), purified water will also remain laundry next time and use, cannot use when secondary laundry.
Application No. is 03256181.4 Chinese patents to disclose a kind of water-conservation washing machine, sets before the water outlet of washing tub
There is prefiltration device, it is additionally provided with water butt, and the bottom of water butt is equipped with flocculation basin, and the top of flocculation basin is equipped with filter device,
Flocculation basin is connected by pipeline with washing tub, and flocculation basin also has sewage draining exit, and pipeline is equipped with pump.
