Content of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, provides a kind of water-conservation washing machine method for controlling water level,
Using bucket SEA LEVEL VARIATION in the level sensor cooperation monitoring in flow of inlet water valve and outer barrel, overcome lacking of washing machine inner tub spilling water
Fall into.
For solving above-mentioned technical problem, the present invention using the basic conception of technical scheme is：
A kind of water-conservation washing machine method for controlling water level, this washing machine is provided with the flow valve of detection inflow, outer barrel on water inlet water route
It is provided with level sensor, bottom discharge mouth is provided with drain valve, interior bucket is only provided with dewatering hole, interior bucket during washing/rinsing on top
For water-containing structure, in washing/rinse cycle, the water in interior bucket is thrown away to outer barrel by top dewatering hole, and level sensor detects
Water level in outer barrel, according to the variable quantity of water level in outer barrel, controls flow valve to open, in moisturizing to interior bucket.
Further scheme is that the amount of washing machine moisturizing is the fixed amount setting, when the variable quantity of water level in outer barrel reach default
During fiducial value, the water of fixed amount mended by inside bucket.
Or, the alternative of such scheme is that the water level in level sensor real-time detection outer barrel, when the change of water level in outer barrel
When change amount reaches default fiducial value, flow valve is controlled to mend the water of set amount to interior bucket, rate of water make-up is correspondingly arranged with fiducial value.
Further, fiducial value and rate of water make-up corresponding with this fiducial value relevant with each program of washing machine it is preferred that same ratio
Relatively it is worth different with rate of water make-up corresponding in rinse cycle in washing.
Again or, the alternative of such scheme is, level sensor is spaced the water level that setting time detects in outer barrel, washing machine
It is preset with different preset range and rate of water make-up corresponding with each preset range, when the variable quantity of water level in outer barrel reaches a default model
When enclosing, control in flow valve benefit and the water extremely interior bucket of this preset range corresponding amount.
Further, preset range and the corresponding rate of water make-up of this preset range relevant with each program of washing machine it is preferred that same
Preset range is different with rate of water make-up corresponding in rinse cycle in washing.
Further, during the moisturizing of washing machine inside bucket, level sensor continues the water level in detection outer barrel, works as sensed water level
Uprise, then stop covering water.
Further, washing machine inflow, flow valve detection inflow not up to sets inflow, in level sensor detection outer barrel
Water level increases, then stop water inlet and start washing/rinsing.
Further, start washing/rinsing after water inlet, level sensor detects that the initial water level H0 of outer barrel simultaneously stores, washing/
Detect outer barrel water level H in rinse cycle, calculate the variable quantity △ H=H-H0 of water level, judge whether to reach default fiducial value, if
Not up to then continue detection, if reaching, the outer barrel water level of this detection is simultaneously designated as H1 storage by execution moisturizing, when completing for the first time

Amount △ H=H-H1, judges whether to reach default fiducial value, if not up to, continuing detection, if reaching, executing second moisturizing
And the outer barrel water level of this detection is designated as H2 storage, according to above-mentioned steps execution, until completing washing/rinsing.
Further, every time before interior bucket draining, open outer barrel drain valve, first outer barrrel water discharged, then start to arrange the water in interior bucket,
By opening bottom of the barrel water drainage or using interior bucket rotation from top dewatering hole draining.
Further, in washing/rinse cycle, when level sensor detects the discharge level H ' that outer barrel water level H reaches setting,
Open drain valve, the water in outer barrel is discharged, draining finishes, again detect outer barrel water level and store initial as moisturizing judgement
Water level.This design is to prevent outer barrel water excessive, can be back in interior bucket from gimbal lower edge dewatering hole, therefore when reaching
This discharge level, needs completely or partially to discharge water, due in washing/rinse cycle afterwards it may also happen that interior bucket water dumping extremely
Outer barrel is it is therefore desirable to the water level in outer barrel store the initial water level judging as moisturizing after detection draining.
Further, the corresponding height of discharge level H ' in outer barrel, the not higher than level height at interior bucket top dewatering hole place.
Further, drain valve open set time or detection outer barrel in water level decreasing to a setting value when, be judged as draining
Finish.
Further, in washing machine work process, when front n times detect the discharge level H ' that outer barrel water level H reaches setting,
Open drain valve execution draining, when the N+1 time detection outer barrel water level H reaches the discharge level H ' of setting, then washing machine judges
Flow defective valve, executes fault alarm, and N is setting value.N value and washing of drum type washing machine time, water level, washing rotating speed, negative
The relating to parameters such as carrying capacity, the discharge level H ' of medicated clothing material, the fiducial value judging whether moisturizing and rate of water make-up and setting.
After technique scheme, the present invention compared with prior art has the advantages that.
The interior bucket of washing machine of the present invention had been both dehydration barrel, and also for steel ladle, washings need not enter into area between the inner barrel and outer barrel
Domain, only need to inject interior bucket suitable amount of water, thus significantly saving slurry, water-saving rate has reached 30%～40%；Separately
