It include route 1 and route 3 on the first washing machine, and second of washing machine then includes above-mentioned three kinds of roads
Line, the filtering line that can reach filter is considered to be worth doing and self-cleaning purpose.
In bleeding stage, interior bucket remains static common rotary drum washing machine with impeller, is just dehydrated after the completion of draining
Program.Washing machine with self-cleaning filter in drainage procedure, line consider to be worth doing due to reverse flow effect and be washed from
Drainpipe discharge.But since line bits are recycled in washing or rinse stage by multiple, it may cause line bits and more stiffly adhere to
In filter, only relying on the more regular washing water flow of bleeding stage can not cause thoroughly to clean to line bits.In route 3,
Bleeding stage washing water is discharged outside body according to specific route, and water flow is relatively stable, washes away the line bits of filter with one
Fixed limitation.
The present invention provides a kind of control method of washing machine, which includes self-cleaning program, the automatically cleaning
Program is moved by interior bucket and/or impeller, keeps the relative motion amplitude between washing water and filter bigger or increasingly complex, thus
Achieve the purpose that further to clear up the line bits adhered on filter.
As shown in figure 9, the step of control method of the invention are as follows: when bleeding stage starts, drain valve is opened, washing machine
Control system judge whether the self-cleaning program needs to open, judging result be it is no, then bleeding stage interior bucket and impeller not into
Row movement, washing machine are drained and are dehydrated according to conventional program；If the determination result is YES, then self-cleaning program is opened.From
Cleaning procedure is opened and closed for the movement of interior bucket and/or impeller on certain opportunity.
Due to being set to bleeding stage in self-cleaning program, inside interior bucket there is clothing and a large amount of washing waters, interior bucket to have
Certain weight bearing, interior bucket are moved in this stage, need to consume a large amount of electric power, cause entire washing machine electric power bear and
Hardware deterioration, thus self-cleaning program is preferably in bleeding stage, remaining washing water to a certain extent when open.
Preferably, first water level of machine set, when the discharge level in drainage procedure reaches the first water level, from
Cleaning procedure is opened.
The opportunity closed for self-cleaning program can be set are as follows: self-cleaning program discharge level in drainage procedure reaches
First water level is opened, and is terminated after opening duration T；Alternatively, the washing machine also sets the second water level, in drainage procedure,
Self-cleaning program unlatching when discharge level reaches the first water level, the closing when discharge level reaches the second water level.
Time point after above-mentioned self-cleaning program duration T is no more than the time point that bleeding stage terminates, that is, is draining
Before stage terminates, self-cleaning program is completed.
The purpose for setting the second water level is to guarantee bleeding stage between the inner barrel and outer barrel there is water to carry out to filter
It washes away, after draining, there is no washing water, then self-cleaning program is nonsensical around filter.
Self-cleaning program independently of washing machine washing procedure, the washing procedure include it is traditional impregnate, wash
Links, the self-cleaning program such as washing, rinse, being dehydrated can open in any drainage procedure in above process, can also carry out individually
Water inlet link after carry out drain operation in open, it is preferable that the last time before complete washing procedure terminates drained
Cheng Kaiqi self-cleaning program, the purpose being arranged in this way are, both can guarantee that a large amount of lines bits in washing course of washing machine carry out
Thoroughly cleaning is concentrated, and is unlikely to be switched on and generate a large amount of consumption of electricity in each draining.
Since the clothing of washing is different and the difference of washing procedure, the line bits of filter traps may have different
Amount, thus the unlatching needs of self-cleaning program are set according to specific situation.
There may be a small amount of line bits in primary complete washing process, and since filter washs in drainage procedure
Water can take away partial line bits, thus be not turned on that self-cleaning program is also unlikely to result in blockage to lint filter in the process.
The material of the clothing of washing is different, and the line bits amount of generation is different, for example the line bits amount of the generations such as knitting wool fabric is opposite
It is more, for the cleaning for guaranteeing filter, self-cleaning program can be opened in each drainage procedure to avoid the blocking of filter.
Self-cleaning program can equally be opened when not washing clothing, user in use for some time can periodic cleaning,
A certain amount of water is injected in interior bucket, corresponding function is selected, self-cleaning program can be opened, completes primary individually automatically cleaning journey
Sequence.
In above-mentioned route 3, the washing water in drainage procedure passes through gravity or draining pump due to the unlatching by drain valve
Guidance and flowed to discharge pipe line, there is no the disturbance of other hardware in flow process, thus water flow is relatively stable, to filtering
The flushing of device is also more mild, is unable to reach thorough clean purpose for more obstinate line bits.Self-cleaning program it is specific
