Abstract

To utilize used bathtub water for a final rinsing also in order to save water, and keep a cleanness. When used bathtub water remains at the time of a final rinsing process, a rinsing with accumulated water or a rinsing with jetted water for which the bathtub water is used, is performed, and after that, a final finish rinsing(clean shower rinsing) is added. In the clean shower rinsing, a water supply solenoid valve 27 is opened, and while a water supply from a tap water supply passage 26 is being performed, a washing tank 13 is slowly rotated. As a result, even if lint being mixed in the bathtub water adheres to laundry, the lint is washed away, and a cleanness is kept.

Description

Washing machine and its control method

The present invention is relevant for washing machine, especially relevant for the washing machine that tap water supply road and water supplying pump road are set and its control method.

With the washing machine of pulsating pump, establish tap water supply road feed water valve respectively, water supplying pump road pulsating pump is implemented the water supply for Wash tub via the running of the keying of controlling feed water valve and pulsating pump.Usually, the water supplying pump road for the surplus water that effectively utilizes the bathroom in the washer, the operating portion of this kind washing machine is provided with the water supplying pump road that is selects the surplus water in bathroom whether to be used in the required enter key of laundry.

But washing machine is implemented laundry processes, flushing process, order such as dehydration consecutive laundry processes.Wherein, flushing process implement usually most times for example two inferior.In process of washing in the past, there is water to implement the what is called " water filling flushing " of flushing in continuing in Wash tub, to supply water, and is stored in state in the Wash tub by the water of scheduled volume and implements two kinds of the what is called " water storage flushing " of washing etc.

But be to have multiple primary flushing to become " dehydration flushing " person's commercialization recently by the viewpoint that conserves water.This kind dehydration flushing is, the degree of the comprehensive water leaking-in of substrate is implemented for Wash tub and made Wash tub (drench pit) rotation and implement dehydration at a high speed after supplying water, and flies out along with moisture and implements flushing through planting dehydration action laundry detergents thus.Dehydration is washed, owing to only need make the degree of water infiltration substrate implement water supply, relatively water storage flushing or injection flushing can be expected conserving water of a great deal of.

As previously mentioned, dehydration flushing is for the very big effect of performance that conserves water, and needn't conserve water but utilize through the water supplying pump road under the situation of surplus water in bathroom, and washing (-)off properties or flushing performance are important all the better.Generally be used for relatively its flushing performance height of dehydration flushing of water storage flushing, establish as unnecessary inhibition and make water consumption, should adopt water storage flushing or water filling flushing.

But, be mixed with dirty thing or soap bits etc. in the surplus water in bathroom and not fine on the health.These dirty dirt are removed a certain program for removing filter via the dirty dirt of the suction inlet on water supplying pump road, but can not be called fully.Because this, especially the final flushing process before dehydration utilizes the situation user of the surplus water in bathroom that very big resistance is arranged psychologically, does not generally all utilize the surplus water in bathroom when therefore finally washing engineering.

The present invention is for addressing the above problem, and its purpose is to be provided as to expect to conserve water and effectively is used in laundry with the surplus water in bathroom, and can implement wholesome washing machine.

The washing machine that proposes for the present invention who solves foregoing problems is, in tap water supply road and water supplying pump road are set, possess respectively control be arranged on the keying of feed water valve on this tap water supply road and this water supplying pump road pulsating pump running and implement the water supply control apparatus that supplies water for washing machine, implement thus in the washing machine of once above flushing process of laundry processes and dehydration, possess

(a) for select laundry processes and/or once the having or not of aforementioned water supplying pump road of above flushing process utilize the input unit of operating,

(b) select under the situation of utilization on water supplying pump road via the final flushing process in the once above flushing process of the operation of this input unit, this final flushing process is implemented any one in water storage flushing or the water filling flushing, and this final flushing process is ended back aforementioned feed water valve of breakdown and appended that to make the operation controller of finally finishing flushing process of aforementioned Wash tub rotation be feature when implementing the water supply on aforementioned tap water supply road.

At aforementioned washing machine, operation controller is that at first whether the final flushing process in the flushing process more than the judgement once selects the utilization on water supplying pump road.If as under the situation of the utilization on selection water supplying pump road,, continue to implement water storage after making the pulsating pump action and implementing the predetermined water level that supplies water to Wash tub and wash, or arbitrary process of the flushing of the water filling in the running of pulsating pump as final flushing process.And, before the dehydration, append execution especially and finally finish flushing process after final flushing process is ended.Finally finish flushing during engineering at this, the breakdown feed water valve also makes the Wash tub low speed rotation when implementing water supply to Wash tub by the tap water supply road.Because this dirty dirt that is attached to substrate is washed by stream.

Since this, according to washing machine of the present invention, even since final flushing process when utilizing the surplus water in bathroom owing to wash via finally finishing the dirty dirt stream that flushing process will be attached to substrate, the result can implement the flushing of cleaning.Moreover, because it is few finally to finish the use amount of the employed running water of flushing process, can suppress the rising of expense.

The present invention also is in aforementioned washing machine, to possess the flow detector on tap water supply road in addition again, and operation controller is a feature for the washing time of finally finishing flushing process according to the testing result decision of this flow detector.

According to environment for use, condition and different weakens finally finishing the cleaning strength of flushing process for the dirty dirt that is attached to substrate under the few situation of flow by the flow of the water on tap water supply road.At this, prior to finally finishing the flow of flushing process by the water on flow detection check and correction tap water supply road, operation controller is that flow prolongs washing time after a little while, controls the action of feed water valve and the rotation of Wash tub otherwise flow shortens the mode of washing time for a long time.

Because this can be avoided finally finishing the waste of the water of flushing process, can implement cleaning and efficient flushing.

And, be that also aforementioned flow detector is, by the condensate tank of dehumidifier that detects the water level in the Wash tub, and constituted by the flow routing device that rises to the required Time Calculation flow of predetermined water level, aforementioned operation controller is the running that temporarily stops pulsating pump when the water supply of final flushing process, water level in the breakdown feed water valve and implementing by the water supply on the tap water supply road water supply with instead of pump water supply road, this moment Wash tub is detected by condensate tank of dehumidifier and obtains the flow on tap water supply road by rising to the required time of predetermined water level.

According to this, device such as flowmeter can be do not appended and the flow on tap water supply road can be calculated, implement cleaning under the condition of cost that therefore can raise hardly and high efficiency flushing.

The control method that the present invention also proposes washing machine is, tap water supply road and water supplying pump road are set, and implement laundry processes via operation controller, and in the washing machine of implementing the flushing process more than twice, when operation controller was selected no longer to implement in the water supply of the flushing process before final flushing process under the situation of utilization on water supplying pump road by the water supply on water supplying pump road for each flushing process, not appending when the remaining water supply of this flushing process and subsequent the water supply of water supply process are implemented by the tap water supply road and finally finishing flushing process was feature.

That is, operation controller is that in the flushing process beyond final flushing process, the situation of water storage flushing is before predetermined amount of water is stored in the Wash tub, the situation of water filling flushing for testing pump in the way of flushing supply water unusual the time, breakdown feed water valve and shift to tap water supply.At this moment, because the water supply of final flushing process is all supplied with by the tap water supply road, no longer append and finally finish flushing process.

Because this, during according to aforementioned control method for washing machine, even under the situation that the surplus water conservancy in final flushing process selection bathroom is used, the surplus water in bathroom has used up and final flushing process does not need to implement when using running water to implement and finally finishes flushing process, can avoid the increase of use amount of water or the prolongation of washing time etc. thus.

Control method for washing machine of the present invention also is, operation controller is, when final flushing process was selected no longer to implement the water supply on water supplying pump road under the situation of utilization on water supplying pump road in the water supply of this final flushing process, appending execution when the remaining water supply of this final flushing process is supplied with by the tap water supply road, finally to finish flushing process be feature.

That is operation controller is, in final flushing process, under the situation of water storage flushing in predetermined amount of water is stored in Wash tub before, the situation of water filling flushing for testing pump in the way of flushing supply water unusual the time, breakdown feed water valve and shift to tap water supply.At this moment, the flushing water of final flushing process becomes the water sent here on the water supplying pump road and running water confession and the mixer of the water sent here sneaks into the possibility height of dirty dirt thus.Therefore appending execution finally finishes flushing process.

Because this during according to aforementioned control method for washing machine, replenishes running water for not enough moisture under the situation that the surplus water in bathroom uses up in the way of final flushing process, implement and finally finish flushing process in the final flushing back of ending, therefore can implement the flushing of cleaning.

Control method for washing machine of the present invention is, in aforementioned first washing machine of implementing the flushing process more than twice, operation controller is, laundry processes select the water supplying pump road utilization situation and also when in the water supply of this laundry processes, no longer implementing water supply by the water supplying pump road, when the remaining water supply of this laundry processes is implemented by the tap water supply road, implemented by the tap water supply road with the degree of the complete water leaking-in of substrate as the flushing process of the front of final flushing process and to implement the dehydration flushing of Wash tub by rotation at a high speed when supplying water, finally to finish flushing process be feature and do not append.

That is, in the water supply way of laundry processes, no longer to implement under the situation of water supplying pump, running water is all used in the remaining water supply of laundry processes and the water supply of flushing process.Owing to this, do not produce the reverse side of the problem of health face, the problem of the use amount of running water takes place.Because this, operation controller is, substitutes not append finally to finish flushing process and change the less dehydration flushing of use amount of implementing water with the flushing process beyond the final flushing process.In dehydration flushing, operation controller is, breakdown feed water valve and Wash tub is slowly rotated when implementing the water supply on tap water supply road at first, and it is comprehensive to make water infiltrate substrate.Then, closed feed water valve rotates Wash tub at a high speed.Because this infiltrates in the laundry detergents and the moisture of substrate and flies out jointly.

Because this during according to aforementioned control method for washing machine, implements the dehydration flushing by the flushing process of the front of final flushing process under the situation that the surplus water in bathroom uses up in the way of laundry processes, therefore can suppress the use amount of water.

The water level L that is represented by dotted lines in the Wash tub 13 among the figure ₁～L ₄For corresponding respectively to 4 laundries (or flushing) water level pattern " seldom ", " low ", " in " reach " height " person.Moreover, be set in water level L ₁The water level L of lower position more ₀For, be called the required check and correction water level (being designated hereinafter simply as " involution water level ") of abnormality that rapid detection is supplied water.

Secondly, with reference to the enter key configuration of the operating portion 11 of Fig. 2 key diagram 1.Operating portion 11 is, the input part 40 that constitutes by the enter key of majority, and show that enter key operates the institutes such as display part 41 of selected pattern or numerical value and constitute.The function of each enter key of input part 40 below is described in regular turn.

Water level options button 42 is, the water yield corresponding to the amount of substrate during with laundry processes and flushing process is by " seldom ", " low ", " in ", the operator is by the required enter key of manual selection in 4 patterns of " height ", and the mode of being lit a lamp by the part of selected water level pattern in the display part 41 constitutes.Be shown in L among Fig. 1 corresponding to the water gages in the Wash tub 13 of these 4 patterns ₁～L ₄The position.And the water level when laundry processes and flushing process is common, selects suitable water level automatically corresponding to the amount of the substrate that the load capacity sensor detected, and shows selected water level pattern thus.

The surplus water conservancy in bathroom is through the surplus water in bathroom that water supplying pump road 28 is supplied with, to be selected to be used in laundry processes, first flushing process, any one required enter key of second flushing process by the operator with key 43.As shown in Figure 3, at once make when the surplus water conservancy in bathroom being pushed with key 43 at every turn and utilize the process of the surplus water in bathroom to change, and the mode that the part in the corresponding display part 41 is lit a lamp constitutes.

Procedure Selection key 44 is, kind or filthy degree corresponding to substrate, by selecting 1 enter key that program is required in the program for washing of the majority that is predetermined laundry time or current etc., and constitute by the mode of lighting a lamp corresponding to the parts in the display part 41 of selected program.

Moreover hobby procedure Selection key 45 is, the time that the operator freely sets laundry or dewaters, required enter keies such as the number of times of flushing, corresponding to the value of input operation by display part 41 demonstrations.These setting values are with temporary memory, select " program that oneself is liked " by procedure Selection key 44, can implement a series of laundry processes according to the program of being remembered thus.

Other, preengaging key 46 is, the reservation required enter key laundry zero hour, and detergent dissolving key 47 is, when use was not easy to be dissolved in the washing powder of water, substrate devoted the enter key of operating under the situation by strong current dissolving washing powder in advance before the Wash tub 13 in Wash tub 13.

Next circuit that will possess relevant for the washing machine of water supply control apparatus of the present invention constitutes with reference to Fig. 4 explanation.For the control part 30 that mainly constitutes, by the input part 40 enter key input signals of operating portion 11, by water level sensor 25 input water level detecting signals by micro computer.Control part 30 is for having the memory of accommodating the running degree, accept the key input that input part 40 is sent here,, control the motor driving part 31 of CD-ROM drive motor 15 respectively according to corresponding running formula, water supply electromagnetic valve 27, the running or the running of pulsating pump 29 and drain solenoid valve 22 etc.Moreover, implement aforementioned demonstration corresponding to key input signal by display part 41.

Have aforementioned formation washing machine basic laundry processes flow process as shown in Figure 5.Control part 30 is according to the running formula, at first implements laundry processes, continuous implements first flushing in regular turn, and second flushing process is implemented dehydration at last.As previously mentioned, operate hobby procedure Selection key 45, can also only implement the laundry processes of a part thus via the operator.

Below, a series of processing action of washing machine of the present invention is by the flowchart text of Fig. 6 and Fig. 7.

Select the laundry water level via enter key operation, when the surplus water conservancy in bathroom such as used at back operation initiate key 48, control part 30 be according to the formula entry into service of turning round.At first, judge whether to set laundry processes (step S10) that is, the situation that contains laundry processes in the program for washing that sets moves down progressive rapid S11, the situation that does not contain laundry processes is shift-in S15.

Set under the situation of laundry processes, control part 30 is implemented laundry processes.At first start pulsating pump 29, via the water supply (step S11) of the surplus water in 28 beginning bathrooms, water supplying pump road.According to the detection signal of water level sensor 25, the water levels in the Wash tub 13 arrive by the selected laundry water level of operator or when arriving laundry water level corresponding to the amount automatic setting of substrate the running of (step S12) pulsating pump 20 stop (step S14).That is, until arrive corresponding to " seldom ", " low ", " in ", the water level L of arbitrary water level pattern of " height " ₁～L ₄Till the surplus water in bathroom continue to supply water.At this, laundry detergents can drop into before water supply automatically, can also the operator drop into voluntarily.

Until the water level in the Wash tub 13 arrives between the laundry water level, judge that the unusual repetitiousness that has or not of water supplying pump is implemented the judgement (step S13) that has or not water level to rise.At this moment, for example know that through the detection signal of out-of-date water level sensor 25 the water level a certain amount of above situation that rises judges to supplying water normally for there being 5 seconds.And, be back to step S12 under the normal situation that supplies water, judge once again whether the water level in the Wash tub 13 arrives the laundry water level.Because this uses up and wait water supplying pump unusual unless produce the surplus water in bathroom, via the processing of step S12～S14, the water levels that water supplying pump proceeds in the Wash tub 13 always arrive till the water level of doing washing.

When the water level in the Wash tub 13 arrives the laundry water level, implement laundry (step S16), at this moment, control part 30 is implemented low speed rotation for the control via motor driving part 31 only makes the rotation wing 14 with predetermined rotating speed, implements laundry thus.After implementing scheduled time laundry, breakdown drain solenoid valve 22 makes the filthy laundry detergents water in the Wash tub 13 discharge (step S17) by water discharge outlet 20.

Continuing it, is effectively to implement flushing to implement middle dehydration (step S18).In the centre dehydration, control part 30 makes the laundry detergents water that infiltrates in substrate fly out for control motor driving part 31 makes Wash tub 13 and the 14 common rotations at a high speed of the rotation wing thus.At this moment, drain solenoid valve 22 becomes the breakdown state.

Do not set at step S10 under the situation of laundry processes, according to water level sensor, 25 detection signal judges whether the water level in the Wash tub 13 is involution water level L ₀More than (step S15).Usually, the state after the water in the time started point Wash tub 13 of laundry all becomes draining, if but the operator by manual operation, the situation that the still remaining state of employed water begins to do washing before then having, it is interior etc. to check therefore whether water is stored in Wash tub 13.

At step S15 water level at involution water level L ₀Above situation moves down progressive rapid S17, dehydration in the middle of implementing after the water in the Wash tub 13 is discharged.Water level is lower than involution water level L ₀Situation move down progressive rapid S18, dehydration in the middle of directly implementing thus.

Be judged as at step S13 under the situation of no water level rising, can be judged as because the surplus water in bathroom has used up or the reasons such as plugged filter of suction inlet can't be implemented water supplying pump.The running of pulsating pump 29 stops in such cases, water supply electromagnetic valve 27 breakdowns and begin water supply (step S19) by tap water supply road 26.According to the detection signal tap water supply of water level sensor 25 water supply electromagnetic valve 27 closures to the water level of doing washing.Moreover, implement laundry via the processing of step S20～S22 identical, draining and middle dehydration with step S16～S18.

After dehydration ends in the middle of step S18 or the S22, judge whether a time process is the process (step S29 or S23) of final flushing.That is, only implement beyond the program for washing of 1 flushing, a time process is not final flushing during the judgement of administration step S29 or S23 at first.

Being final flushing process in S23 time one process of step, situation moves down progressive rapid S26, and breakdown water supply electromagnetic valve 27 and beginning are by the water supply on tap water supply road 26.And according to the detection signal of water level sensor 25, tap water supply is water supply electromagnetic valve 27 closures when washing water level.

In S23 time one process of step is not under the situation of final flushing process, that is the situation of implementing first and second twice flushing process moves down progressive rapid S24, at first washes as first and breaks through journey and implement the dehydration flushing.In dehydration flushing, drain solenoid valve 22 is the state of breakdown under the purpose of the final discharge laundry detergents water of directly keeping laundry processes.Water supply electromagnetic valve 27 breakdowns, running water supply water in Wash tub 13.At this moment, control part 30 control motor driving parts 31 make the Wash tub (drench pit) 13 and the rotation wing slowly rotate thus.Because this slowly implements in the rotation via Wash tub 13 and to supply water, fully moisture is descended and make substrate infiltrate moisture content comprehensively for the substrates in the Wash tub 13.The output of this moment is, for example be several liters to 10 liters programs, and it is especially few that the needed water yield is washed in comparison water storage flushing or water filling.

After the state that comprehensively infiltrates moisture content by substrate is implemented the water supply of the scheduled time, water supply electromagnetic valve 27 closures.After this, Wash tub 13 is implemented dehydration to rotate at a high speed between the scheduled time.Fly out jointly through dewatering thus, infiltrating in the laundry detergents and the water of substrate, the result is discharged by water discharge outlet 20.After the dehydration flushing ends, with the S25 execution middle dehydration same with step S22.

The dehydration flushing is, as previously mentioned, become with a series of flow process of the dehydration of high speed rotation by the water supply in the Wash tub 13 slow rotations, but as first flushing process, a series of flow process of this kind is implemented as most for example two circulations that circulate of circulation person's repetitiousness execution and also can.

After the dehydration flushing process that is first flushing process are ended, or only set under the situation of flushing process once, control part 30 is for implementing second flushing process.This kind second flushing process is implemented the water storage flushing.In second flushing process, the beginning tap water supply by the state breakdown water supply electromagnetic valve 27 of closed row water solenoid valve 22 at first, the water levels to Wash tub 13 of always supplying water arrive closed water supply electromagnetic valve 27 (step S26) till the flushing water level.At this moment, can also devote in the flushing water attaching agent (clothing class softener).

When the water of scheduled volume is stored in Wash tub 13, control part 30 is control motor driving part 31, only make the rotation wing 14 low speed rotation (Wash tub 13 does not rotate) (step S27) thus, the washing time of this moment is, group is gone into the value of the running formula in the control part 30 in advance, and standard value is approximately 2 minutes degree.And drain solenoid valve 22 breakdowns after the rotation of flushing ends, flushing water are all discharged (step S28) by water discharge outlet 20.

On the other hand, be not under the situation of final flushing process in S29 time one process of step, that is the situation of implementing first and second flushing process move down progressive rapid S43, first flushing process is implemented the water storage flushing of using the surplus water in bathroom.In this kind water storage flushing process,, arrive the preceding water supply of implementing the surplus water in bathroom of flushing water level via the processing of step S43 and S44.Under the situation that the surplus water generates in bathroom is unusual in supplying water on the way, shift-in step S40 shifts to tap water supply.Because this, the flushing water of first flushing process of this kind situation becomes the mixing water of surplus water in bathroom and running water.

After this, implement water storage flushing (step S47), after the water storage flushing ends, discharge flushing water (step S48).Continue it, via the processing of the step S49 same～S52 with step S25～S28, dehydration and second flushing process (water storage flushing) in the middle of implementing.

The N/R situation of water supply of the surplus water in bathroom moves down progressive rapid S45 when the water supply of step S44 first flushing process, is back to step S17 after the water storage flushing of execution with the surplus water in bathroom.Described draining (step S17) before implementing, middle dehydration (step S18) is implemented the judgement whether process is final flushing once again at step S29.Under the situation of present embodiment, the judgement of step S29 must make a time process become final flushing process shift-in step S30 when becoming for the second time.

Step S30, S31 are and step S43 that the processing that S44 is same continues to implement the water supply of the surplus water in bathroom before arriving the flushing water level.The situation that the water supplying pump in the way of supplying water produces different shape moves down progressive rapid S40, shifts to tap water supply.During beginning by water supply electromagnetic valve 27 breakdowns to end to supplying water after the water supply on tap water supply road 26, implement the flow rate test (step S41) of running water.The details aftermentioned it.Flow rate test is, according to the detection signal of water level sensor 25, by the required time judgement flow of the water level that rises to scheduled volume.Water supply electromagnetic valve 27 closures when the water level in the Wash tub 13 arrives predetermined flushing water level are implemented water storage flushing (step S35) thus.

The N/R situation of water supply of surplus water moves down progressive rapid S32 in step S31 bathroom, implements the flow rate test of running water thus.Implemented water supplying pump this moment, but the moving commentaries on classics of pulsating pump 29 temporarily stops, water supply electromagnetic valve 27 breakdowns and by tap water supply road 26 water supply starts.And S41 is same with step, according to the detection signal of water level sensor 25, by judging flow for the required time of the water level rising of scheduled volume.When flow rate test at the end, water supply electromagnetic valve 27 closures make pulsating pump 29 starting once again and begin the water supply (step S33) of the surplus water in bathroom once again.That is, only temporarily implement tap water supply for the flow rate test on tap water supply road 26.After this, the water of flushing water level is stored the surplus water water supply in preceding bathroom and is produced (step S34) shift-in step S42 under the unusual situation, shifts to tap water supply thus.

After the mixing water of surplus water of surplus water in bathroom or bathroom and running water arrives predetermined flushing water level, implement water storage flushing (step S35) as second flushing process.After water storage flushing ends, drain solenoid valve 22 breakdowns and discharge flushing water (step S36), dehydration (step S37) in the middle of implementing then.Because second flushing process (final flushing process) uses the surplus water in bathroom, implement as the 3rd flushing process and finally finish flushing (clean water flushing) (step S38) in such cases.

In the clean water flushing, control part 30 is that breakdown water supply electromagnetic valve 27 is implemented the water supply on tap water supply road 26.This moment, drain solenoid valve 22 became the breakdown state.When supplying water, control part 30 is controlled motor driving part 31 for Wash tub 13 and the rotation wing 14 common slowly modes of rotation.This moment, the example of control time figure was Fig. 8.In the time of water supply electromagnetic valve 27 breakdowns, the mode of the galvanization one obstructed electric current of 1.5 seconds motor 15 of repetitiousness execution is controlled motor driving part 31.Because this, same with preceding half the action that dehydration is washed, Wash tub 13 is slowly implemented water supply by top in the rotation.This kind result falls moisture content for the substrate in the Wash tub 13 comprehensively, and the dirty dirt that is attached to substrate is discharged jointly with laundry water.

Be to set corresponding to the flow of the running water that step S32 or S41 tested the duration of runs of clean water flushing.That is, therefore the active force of dirty dirt of substrate is strong makes it become the short duration of runs because the swash of wave is attached under the many situation of the flow of running water, otherwise that the few situation down-wass of the flow of running water is attached to the active force of dirty dirt of substrate is weak and need the long duration of runs.

Specifying it, for example is to determine the duration of runs by following manner.In the flow rate test of running water, be lower than involution water level L by the arrival of the water level in the Wash tub 14 ₀The time point of the position of 20mm is to arriving involution water level L ₀Time till, that is test water level rising 20mm required time T.And, time T be 16 seconds less than the time be speculated as flow L more than 15 liters/minute, the clean water flushing is set at 36 seconds the duration of runs.Time T be more than 16 seconds 24 seconds less than the time flow L for being speculated as below 15 liters/minute more than 10 liters/minute, clean water flushing duration of runs is for being set at 54 seconds.Time T is that flow L is speculated as below 10 liters/minute more than 24 seconds the time, and the clean water flushing was set in 108 seconds the duration of runs.

So between the duration of runs of setting, after the flushing of execution clean water, control part 30 is to implement dehydration (step S39) at last.Moreover, implement under the situation of water storage flushing, also implement dehydration equally at last.In dehydration, drain solenoid valve 22 keeps under the state of breakdown, Wash tub 13 and the 14 common rotations at a high speed of the rotation wing.This kind result infiltrates in the flushing water of substrate and is flown out and finish dehydration, the overall process of the laundry that ends thus.

And, in the previous embodiment, can also be by implementing the water filling flushing to substitute the water storage flushing.Under the situation of water filling flushing, be stored in the state that also continues the running of pulsating pump 29 behind the Wash tub 13 or become breakdown water supply electromagnetic valve 27, implement flushing in the rotation rotation wing 14 in continuing to supply water via the water of scheduled volume.This moment, water was discharged by the gap overflow that is located at water jacket 12 (Over flow).
