Description
Technical field
The present invention relates to washing machine field, specifically circulating water saving washer, especially a kind of flocculation washing machine with automatically cleaning filtering function.
Background technology
Along with the raising of people's living standard, washing machine is one of main household electrical appliances having become people's daily life now, the laundry processes of washing machine mainly comprises washing, rinsing, dry several stage, at washing stage washing machine inflow and washing agent, clothing is washed, in order to rinse spot and residual washing agent after entering rinse stage, need into more water or perform more rinsing times rinsing is carried out to clothing, the water resource of this at substantial that is bound to, even the roller washing machine of water-saving, also rinsing at least twice is needed in order to rinse clothing, this process at least will consume the running water of more than 30L.Sometimes the washing agent that is less or that throw in of the spot on clothing is less, may twice with regard to rinsed clean, but because user have selected 3 rinsings, also certainly will can cause the waste of water resource, the basic water consumption of general twice washings of automatic washing machine of such as 6Kg is at about 100 liters.How can accomplish water and electric saving while clean clothes, be one of focus of paying close attention to of consumer always.
Not yet there are the matching used Water warfare of washing machine and recycling device so far, even if the so-called washing machine with water-saving function, generally in the position, side of washing machine, water storage tank are installed, water pump is adopted to carry out water filling and draining, generally can a water filling, rinsing 3 times, plays water-saving function.But the water after washing can not be preserved, make the own complex structure of washing machine, huge simultaneously, be unfavorable for transport, recycling etc.Due to the restriction of the aspects such as volume, structure and flexibility, have impact on giving full play to of washing machine original function and the function of water-saving box own.In order to better saving water resource on the basis of existing laundry mode, a lot of producer has dropped into a large amount of research and development.
Existing washing machine is with recirculated water function, and it only plays and filters line bits, and washing is even or add the effect such as ozone, heavy metal ion sterilization.Cannot water consumption be improved, and there is no basic raising to cleaning.
The recycle of laundry water, through consulting Patents document, if application number is " recycling water saving device of washing machine " of 200810072420.5, being inputted by laundry water in a water drum, carrying out purified treatment.This invention is not carried out purification direct for the laundry water of first pass and is run in, and after carrying out purified treatment, uses when wait until laundry next time for the rinsing water of second, third time.
In the above-described techniques, " recirculating water technical " uses after washings purification, and this technology can not recycle first pass laundry water (first wash water), and the water after purification also will be waited until laundry next time and be used, can not use when when time laundry.
In view of this special proposition the present invention.
