Carry out detergent amount and detect processing.This detergent amount detects following carrying out, when the dried cloth state before the supply laundry water makes washing and dewatering tube 3 towards a direction rotation, motor 4 is controlled to be the cloth amount that detects washings based on the drive current integrated value of the motor 4 during the rotation number 2 that accelerates to regulation from the rotation number of stipulating 1, obtains the appropriate amount (detergent amount) of washing agent based on detected cloth amount.Detergent amount is by obtaining with reference to the table of comparisons of predefined cloth amount and detergent amount.
In addition, obtain wash time and setting based on this testing result (cloth amount).When not carrying out the detection of cloth amount, the wash time of established standards.
Step S105
The detergent amount of obtaining is presented on the display 25 of guidance panel 8.
Step S106
The user pulls out washing agent dish 7, and the dosage of powder washing agent that shows is put into washing agent dish 7.Microcomputer 50 is opened water supply electromagnetic valve 16b after waiting for that the user puts into washing agent the 7 needed times of washing agent dish (as 1 minute), to 7 waterings of washing agent dish, powder detergent is flowed in the detergent container 19 implement water supply.Powder detergent with the water of supply from the delivery port 19a of detergent container 19 by bellows A20, flow to the 2a of bottom notch portion of urceolus 2 from the feed water inlet 2a of urceolus 2.
At feed water inlet 2a, water is rectified into the inner peripheral surface (as the arrow of Fig. 4 and Fig. 7 shown in like that mobile) of the flow direction towards urceolus 2 by the plate 11d of steam valve 11, owing to flow along the inner peripheral surface of urceolus 2, so water and washing agent do not flow in the washing and dewatering tube 3.Like this, by the rectified action of plate 11d, can prevent from directly to contact decolouring or the color spot that washings causes because of undissolved powder detergent.
In addition, when washing agent is liquid detergent, the liquid detergent of high concentration flows in the urceolus 2 in order to prevent water supply electromagnetic valve 16b to open before, in washing agent dish 7, liquid detergent is set and uses the place, temporarily deposit at this, be used for using always from the water supply dilution of water supply electromagnetic valve 16b and to urceolus 4 supplies.In the present embodiment, owing to utilize the rectified action of plate 11d, washing agent can not flow directly in the washing and dewatering tube 3, need the place that liquid detergent is used be set in the washing agent dish, can simplify the structure of washing agent dish 7, can realize cost degradation.
Step S107
Water supply stops to supply water behind the detergent dissolution water level.In the present embodiment, control output according to detergent amount (cloth amount).Specifically, detergent amount be 17 restrain 44 the gram, the water yield is about 3 and is raised to 7 liters.The control of output is to carry out according to level sensor 34.This water yield is set the laundry water that generates in detergent dissolution operation (step S108) after this detergent concentration is 10 times to the maximum.At this, detergent concentration is that the specified value concentration (concentration when dissolving 20 restrains washing agent in 30 premium on currency concerning general powder synthetic detergent) detergent manufacturers is defined as 1 times.Make detergent concentration be 10 the reasons are as follows to the maximum.
In general powder synthetic detergent, except that surfactant, also contain ferment, alkaline agent, water softener, fluorescent whitening agent etc. as auxiliary agent.Detergent concentration is too high, has the problem of the color spot (remarkable especially when being shone by ultraviolet ray) of the clothes class that causes because of fluorescent whitening agent.Make this dyeing not serious, just need be suppressed to detergent concentration below 10 times.
Step S108
To 47 energisings of circulating pump motor, circulating pump 24 is reversed, carry out detergent dissolution.The water and the washing agent that accumulate in urceolus 2 bottoms and depressed part 2b pass through flexible pipe 22, filter 23c from water discharge outlet 21, enter in the shell 42 from suction inlet 43.And, discharge from discharge opening B45, by bellows D40, return depressed part 2a from inflow entrance 18 and circulate.Blade 46a, the 46b of detergent use impeller 46 stirs and dissolves, and generates the laundry water of high detergent concentration.The time of detergent dissolution is 1 minute to 2 minutes.
Flow to the flow direction of depressed part 2a when coming out up from inflow entrance 18, meet dividing wall 2b after flow direction change to water discharge outlet 21 sides (the thick arrow among Fig. 5).Therefore, even in the dissolving starting stage, can prevent that also undissolved washing agent from flowing directly in the cylindric washer 3 when containing the water circulation of more undissolved washing agent.But a part of running into the water of dividing wall 2b can flow to urceolus cover 2d side.In urceolus cover 2b side mobile delay part is arranged, probably can pile up undissolved washing agent in this part.
To this, rectification part also can be set make and to return the water of depressed part 2a positively towards water discharge outlet 21 sides.
Figure 15 is the profile that is provided with urceolus 2 bottoms of rectification part 18a at inflow entrance 18.Figure 16 is cutting off from the being seen depressed part 2a of the direction of arrow with double dot dash line C-C line of Figure 15.Rectification part 18a is a cylindrical shape, is arranged in depressed part 2a outstanding.Top tegmentum 18b blocks, and has peristome 18b towards the draining oral-lateral in barrel surface.Peristome 18c is cut off the only about half of of barrel surface and forms.In addition, the opening direction of peristome 18c is towards the sidewall 2a1 side of length direction or the depressed part 2a of depressed part 2a.The water peristome 18c from rectification part 18a shown in thick arrow that comes out from inflow entrance 18 flows to water discharge outlet 21.Owing to the barrel surface that rectification part 18a is arranged in urceolus cover 2d side,, can not pile up undissolved washing agent so water can not flow to urceolus cover 2d side.
In addition, filter 23c is cancellate filter, can not pile up the undissolved powder detergent that passes through.
During detergent dissolution when reversing (circulating pump), because because of the effect of dividing wall 46b, the spue pressure of hole B45a of the pressure ratio of the hole A44a portion that spues is much lower, and water or undissolved washing agent can not flow out in the washing and dewatering tube 3 from nozzle 27a.But undissolved washing agent can enter in the middle of bellows C41 or loop hose 27.To this, when detergent dissolution, circulating pump 24 is temporarily stopped.Circulating pump 24 stops, and the undissolved washing agent that is immersed in bellows C41 or the loop hose 27 returns in the shell 42.And,, can eliminate not dissolving detergent by operation cycle pump 24 once more.Circulating pump 24 temporarily stop at detergent dissolution the time carry out 3 to 4 times.In addition, the dwell time of circulating pump 24 is just enough about 1 second.
Water yield during detergent dissolution is 3 to be raised to 7 liters as mentioned above.For the drum-type washing drying machine of present embodiment, supply with this water yield, water level enters in the washing and dewatering tube 3.Therefore, the laundry water-soaked washings of high detergent concentration during detergent dissolution.At this moment, to motor 4 energisings,, make laundry water soak into washings equably and then can by making washing and dewatering tube 3 low speed rotation (per minute 30 to 40 changes).
When detergent concentration surpassed about 1 times, the surfactant that comprises in the washing agent formed the aggregate that is called micelle.Micelle be the hydrophobic group of surfactant towards the center, hydrophilic group orbicule toward the outer side, its diameter are about 10nm.The central part of the micelle that is surrounded by hydrophobic group, but solvation is big, and the ability of dissolving oily matter and lipid is very high.In addition, the number of micelle is that detergent concentration is high more then many more.
Step S109
Carry out prewashing.This prewashing is, makes washing and dewatering tube 3 rotatings (per minute 35 to 45 changes), and circulating pump motor 47 makes the laundry water of urceolus 2 bottoms fall on the washings from nozzle 27a by circulating pump 24 is just being transferred simultaneously.Washings repeats to be used in the motion that the lifter of the internal perisporium face setting of washing and dewatering tube 3 is kicked up, fallen.Carry out the rotation of washing and dewatering tube 3 and the running of circulating pump 24 off and on, in the stopping period of washing and dewatering tube 3 and circulating pump 24, with reference to the detection signal of level sensor 34 on one side open water supply electromagnetic valve 16b make-up water and make water level be no more than designated water level on one side.By repeatedly repeat this turn round make the laundry water soak washings equably.
When first time washing and dewatering tube 3 rotating, detergent concentration is about 10 times laundry water to be fallen and is impregnated on the washings in this washings.The laundry water of high concentration spills owing to being diffused as the film shape from nozzle 27a, thereby is impregnated into washings equably with the penetrant action of washing agent.Washings for a long time, from the laundry shipwreck of nozzle 27a to be spread across on the washings near the part of washing and dewatering tube 3 peripheries, by in the detergent dissolution of step S108, making 3 rotations of washing and dewatering tube, because laundry water is impregnated into washings from the outer circumferential side of washing and dewatering tube 3, thereby the laundry water saturates is all to washings.
Since comprise a lot of above-mentioned micelles in the laundry water of the high concentration of in washings, soaking into, thus the dissolving greasy dirt, and the effect that dirt breaks away from from washings is very big, obtains high cleaning strength.
By make-up water repeatedly, the detergent concentration of falling the laundry water on the washings descends, and in the prewashing ending phase, becomes about 2 times of normal concentration.
Step S110
Carry out and formally wash.Make washing and dewatering tube 3 positive and negative rotations (per minute 35 forwards 45 to be changeed), circulating pump 24 is just being changeed the laundry water that accumulates in urceolus 3 bottoms is fallen on the washings from nozzle 27a.
At last, stop the running of washings circulating pump 24, the circulation of the water that stops to do washing makes washing and dewatering tube 3 with positive and negative rotation of short period, carries out the running of washing washings by rubbing with the hands, and formal wash time is finished.
Step S111
Carry out rinsing for the first time.In this rinsing, at first, open draining valve 25, discharge the water in the urceolus 3, after detecting draining and finish with level sensor 34, make washing and dewatering tube 3 to a direction (in the present embodiment, being seen as counterclockwise) rotation, the laundry water that contains in the washings is carried out centrifugal dehydration from the front of washing machine.
Then, open water supply electromagnetic valve 16b, running water is supplied with detergent container 19, supplied water up to designated water level in urceolus 3 bottoms from feed water inlet 2a.Secondly, and formally wash similarly, make washing and dewatering tube 3 counter-rotatings (per minute 35 forwards 45 to be changeed), circulating pump 24 is just being changeed, make the washings that accumulate in urceolus 3 bottoms fall washings and circulate, carry out rinsing from nozzle 27a.
Secondly,, detect the water level of the washings that accumulate in urceolus 3 bottoms, carry out moisturizing and make water level be no more than designated water level with level sensor 34 at the state of the running of rotation that stops washing and dewatering tube 3 and circulating pump 24.
Secondly, make washing and dewatering tube 3 counter-rotatings (per minute 35 forwards 45 to be changeed), circulating pump 24 is just being changeed, make the washings that accumulate in urceolus 2 bottoms fall washings and circulate, carry out rinsing from nozzle 27a.Owing to becoming the film shape, the washings from nozzle 27a ejection are spread across on the washings, thus fall on the washings equably, thus can more effectively be diluted in the detergent ingredients that comprises in the washings, can improve rinsing performance.
Then, stop electric circulating pump 24, under the state of the circulation that stops washings, make the 3 positive and negative rotations of washing and dewatering tube with the short cycle, wash running by rubbing with the hands.
Step 112
Carry out rinsing for the second time.This secondary rinsing is to be supplied water in the soft fine purifiation agent input chamber of washing agent dish 7 the additional control that soft fine purifiation agent is dropped into the bottom of indoor soft fine purifiation agent importing urceolus 3 by opening soft fine purifiation agent water supply electromagnetic valve 16c.Action in addition and primary rinsing are similarly carried out.
Step S113
Carry out final processed.Final dewatering be the state of opening draining valve 25 make washing and dewatering tube 3 to a direction (being seen as counterclockwise from the front of washing machine) at present embodiment at a high speed rotation make motor 4 runnings and the washings in the washing and dewatering tube 3 carried out centrifugal dehydration carry out.Be set at the time that obtains the dehydration rate of being hoped the duration of runs of this final dewatering.
Step S114
