Description
Technical field
The present invention relates to washing machine, more particularly to a kind of washing machine with recirculated water filtering function.
Background technology
Workflow during existing conventional washing machine laundry generally includes into water, washing-drying-draining repeatedly rinses-and gets rid of
Dry-draining etc., wherein rinsing is required to consume a large amount of clear water every time.In general, existing pulsator washing machine is once done washing
The water consumption of entire workflow can reach per kilogram clothing 20-30 liters, and once laundry entirely works existing roller washing machine
The water consumption of flow will also reach per kilogram clothing 12L water.That is, existing conventional washing machine（No matter pulsator washing machine
Or tumbling-box washing machine, regardless of being semi-automatic washing machine or automatic washing machine）It is typically that laundry is useless during work
Water is directly discharged to outside washing machine, and refills a large amount of clear water and clothing is repeatedly rinsed, and entire laundry processes is caused to consume
Water is larger.
To realize the purpose of Water-Saving for Washing Machine, the prior art is generally handled laundrywastes using following scheme：
Scheme 1：Increase water tank in washing machine and collect washings, and strainer is set by the washings simple filtration of collection
It is applied to next laundry processes afterwards.
Scheme 2：Increase reverse osmosis filter in washing machine, laundrywastes is purified, and by purified purification
Water application is in next laundry processes.
Scheme 3：Laundrywastes is purified using auxiliary devices such as large-scale water treatment facilities and ozone generators, it will be net
Purified water after change is applied to next laundry processes.
However, the practical application effect of above-mentioned several schemes is undesirable, main cause is as follows.
1 increased strainer of scheme and water tank can only simply remove the line bits in washings.However, since washings are miscellaneous
Matter is more, and water quality is unstable, causes scheme 1 that cannot really solve the quality problem of washings.Moreover, this scheme usually requires people
Work cleans water tank and strainer, and it is inconvenient to safeguard.
Scheme 2 purifies laundrywastes using reverse osmosis filter, this is not only needed using high-pressure pump, and purifies
Production water speed rate is slow, and water yield is it is difficult to ensure that the normal use demand of washing machine.In addition, this scheme need to regularly replace it is reverse osmosis
Filter, cost are higher.
Scheme 3 purifies laundrywastes using auxiliary devices such as large-scale water treatment facilities and ozone generators, these
Auxiliary device is not only expensive in itself, and occupied space is big, and also needs to many corollary apparatus and related cleaning plant, into one
Equipment cost and maintenance cost is significantly increased in step, is completely unsuitable for average family use.
As can be seen that in the washing machine that there is the prior art of circulating water filtering system at itself, such as according to aforementioned side
The washing machine of case 1 and 2, and the automatic cleaning function without filter assemblies lead to filter assemblies cleaning trouble therein or need
It relatively frequently to replace.
And in such washing machine, handle to recycle profit due to be filtered such as washings or washings
With, thus outside the inlet pipeline and discharge pipe line in addition to routine, also to include filtering water circulation pipe.In the prior art
In, typically above-mentioned pipeline is separately provided and controlled, results in the washing machine internal with circulating water filtering system in this way
Pipeline is mixed and disorderly, high failure rate, and control is complicated, is not easy to overhaul and safeguard.
