Then, use Fig. 3, with regard to being described in detail of washing agent throw-in part and detergent dissolution portion.Fig. 3 is the stereogram of washing and dewatering groove 5, cuts away the part of perisporium and represents.Perisporium inboard at washing and dewatering groove 5 is provided with peripheral passage 8 at longitudinal direction.Peripheral passage 8 has washing agent input port 8a on top, gap 10 openings that the lower end forms to the bottom surface by impeller 6 and washing and dewatering groove 5.Be positioned at roughly sustained height above washing agent input port 8a and the balance weight 5b.By inclined-plane 9, the bottom surface of washing and dewatering groove 5 is connected with peripheral passage 8 smooth-goingly, and the washing agent that drops into from washing agent input port 8a drops to peripheral passage 8, with this state, arrives the gap 10 of the interior impeller 6a below of impeller 6.The gap 10 of the bottom of washing and dewatering groove 5 and interior impeller 6a produces stronger current when detergent dissolution, for the dissolving that promotes washing agent narrower.In addition, the structure of the washing agent input port 8a shown in the figure only is an example, so long as the structure that can easily washing agent be put in the peripheral passage 8 all can.
8 the bottom in the peripheral passage is provided with outlet 8b.Outlet 8b is used for the washing agent liquid after the dissolving is discharged in the washing and dewatering groove 5, is impregnated on the washings.The quantity of outlet 8b what are can, but for make washing agent liquid be discharged in the washing and dewatering groove 5 on a large scale in, wish to be provided with a plurality of at above-below direction.In addition, the shape of outlet 8b except that the joint-cutting shape of the horizontal length shown in the figure, also can be vertically long joint-cutting shape or is made of a plurality of holes.
When dropping into washing agent, washing agent remains under the situation of washing agent input port 8a, because it is washed away, think is as the water supply unit 17 and the water supply position of Fig. 4 and structure shown in Figure 5.
Fig. 4 is the vertical view (the A-A cutaway view of Fig. 5) of water supply unit 17.Fig. 5 is the longitudinal section of the washing machine of expression water supply position and current.Water supply unit 17 is to be made of turncock mouth 17a, water supply electromagnetic valve 17b, water supply box 17c.The bottom surface of water supply box 17c is the inclined-plane, and it is minimum making washing and dewatering groove 5 sides, and the feed water inlet 17d of joint-cutting shape is arranged at lowest part.Feed water inlet 17d have make water roughly under the rectified action of flowing, the shape of its peristome also can be to be made of a plurality of holes except that the joint-cutting shape of as shown in the figure horizontal length.
By water supply mechanism, the position of feed water inlet 1 7d that is used for supplying water in water jacket is to be arranged on all sides in the balance weight 5b on top of washing and dewatering groove 5, is positioned at the top of balance weight 5b.So, because water inboard slightly than balance weight 5b inner peripheral surface is membranaceous dirty, thus when supplying water, can not too make water saturates arrive the clothing class, the burden in the time of can being reduced in rotation by impeller and generating high concentration detergent liquid to motor.
In addition, washing agent input port 8a is characterized in that, for making water level from feed water inlet 17d in the position that flows down, and one or more being arranged on the balance weight.According to this formation, can wash away washing agent by supplying water attached to the washing agent input port, can suppress adhering to of washing agent.
Like this, Yi Bian if make 5 rotations of washing and dewatering groove, Yi Bian supply water, then water flows into the washing agent input port 8a in the inboard of balance weight 5b inner peripheral surface, can wash away the washing agent that remains in washing agent input port 8a or the peripheral passage 8.In addition, flow into the water on the washings 50, mobile like that shown in arrow among the figure.Water is owing to flow down in the periphery near washing and dewatering groove 5, so soak the washings 50 of the outer circumferential side that is positioned at washing and dewatering groove 5 gradually, most of surface along washings 50 flows down by the wall of washing and dewatering groove 5 and the gap or the aperture 5a of washings 50, remains in the bottom of water jacket 4.Therefore because water do not immerse the whole of washings 50, so can with because of the weight limits of the moisture washings that increases by 50 in minimum degree.This is very effective under the many situations of the amount of washings 50 particularly, if it is many to immerse the water yield of washings 50, the weight that then acts on impeller 6 becomes big, when dissolving is stirred, existence is pinned the situation that can't fully carry out the dissolving of washing agent because of the weight of washings 50 with impeller 6.In addition, also have if the washing agent that the back that is soaked in water is placed, then can be condensed at short notice.But, by water supply as described above, because can reduce the water yield that immerses washings 50, water is remained in the water jacket 4 at short notice, so can shorten from water supply start to the time that begins to dissolve stirring, shortening is soaked standing time of beginning from washing agent, can prevent that detergent dissolution is insufficient.
It is to begin after level sensor 11 detects the detergent dissolution water level that reaches shown in the figure that dissolving is stirred.This detergent dissolution water level in order to improve the concentration of washing agent liquid, is wished low as far as possible (water yield is few), because the dissolving of the washing agent interior impeller 6a by impeller 6 carries out, so by water supply mechanism, supply with the water that lacks than washing procedure.The detergent dissolution water level is in the bottom of impeller 6, the water level of impeller 6a in the submergence of supplying water.In view of the above, can reduce the load that is applied on the motor, can suppress motor and be lockable.In addition, the detergent dissolution water level can not be subjected to the influence of cloth amount, by carrying out certain control, can suppress washings to the soaking into of cloth, and can simplify control.
By above-mentioned formation, because can dissolve stirring fully, dissolve, so can generate the washing agent liquid of high concentration with the water yield seldom.The detergent concentration of this moment is about about 5-8 times of suitable concentration (1 times) of washing because of the difference of loading is different.
Below, the action of each operation of the washing machine of such formation describes.Fig. 6 is the flow chart of micro computer 25 practiced each operation in the control module 19.
If press the washing start button switch of input switch group 18a, then micro computer 25 is carried out following such control processing.
The user drops into washing and dewatering groove 5 with washings 50, and the input switch group 18a of operating operation panel carries out initial setting, if press washing start button switch, then the automatic running control of micro computer 25 each operation of beginning is handled.
In above-mentioned initial setting,, set wash time or dewatering time, the water yield, wash away number of times etc. according to washing process, the needs corresponding with washings 50.
The cloth amount of carrying out washings 50 detects control and handles.It is under the dried cloth state before washing that this cloth amount detects, the electric operating clutch mechanism 7b of drive unit 7 is controlled at stir mode, the drive motors 7a short time is switched on, rotation drives impeller 6, deceleration characteristic during accelerating performance when quickening based on rotation or the inertia when stopping drive motors 7a switch on rotate detects.According to this testing result, calculate to determine that detergent amount, this detergent amount are used to generate the washings of the washing water yield and appropriate detergent concentration, by tracer atom group 18b, show this detergent amount.The user is reference with the detergent amount of above-mentioned demonstration, from washing agent input port 8a drop into quantitative washing agent.Washing agent from washing agent input port 8a drops into drops to peripheral passage 8, with this posture, arrives the gap 10 of the interior impeller 6a below of impeller 6.
The user closes the lid 16 that is arranged on the overhead guard 15 after dropping into washing agent.If closed lid 16, then micro computer 25 is accepted to open water supply electromagnetic valve 17b, water supply start from the signal that covers switch 23.At this moment, the electric operating clutch mechanism 7b of drive unit 7 is controlled at dehydration mode, makes drive motors 7a low-speed running, Yi Bian make washing and dewatering groove 5 begin low speed rotation about 30 seconds from water supply start, Yi Bian supply water.This is to consider that washing agent remains in the situation in washing agent input port 8a and the peripheral passage 8, is the inside of Washing agent input port 8a and peripheral passage 8.After making washing and dewatering groove 5 low speed rotation about 30 seconds, stop the running of drive motors 7a, do not make 5 rotations of washing and dewatering groove, continue to supply water.Like this, Yi Bian make 5 rotations of washing and dewatering groove, be the water yield that is impregnated on the washings 50 in order to reduce Yi Bian carry out short time water supply, when the detergent dissolution of step 104 described later, reduce the load of impeller 6, positively carry out the dissolving of washing agent.And then, by stopping washing and dewatering groove 5 on the way, continue to supply water, water is remained in the water jacket 4 at short notice, can prevent that washing agent from being soaked and solidifying, produce not exclusively dissolving.
Like this, if level sensor 11 detects and reaches the detergent dissolution water level, then micro computer 25 acceptance are closed water supply electromagnetic valve 17b from the signal of level sensor 11.
Dissolving detergent generates high concentration detergent liquid.In the detergent dissolution operation, the electric operating clutch mechanism 7b of drive unit 7 is switched to stir mode, the positive and negative repeatedly running of control drive motors 7a makes impeller 6 positive and negative rotations.In view of the above,, stir washing agent and water in the gap 10 below the impeller 6a in putting into, generate high concentration detergent liquid by the interior impeller 6a of impeller 6.Control for example is energising in 0.5 second to the conduction time of drive motors 7a, stops in 0.5 second.This is called as the running time limit, shows as 0.5 second on-0.5 off second.If the on overlong time, then washing and dewatering groove 5 by reaction force, shakes in washings 50 strenuous exercises on the impeller 6, and water jacket 4 and housing 1 collision become the reason that produces noise.If consider this thing, then the time of on weak point better is set at the running time limit that can fully carry out detergent dissolution.That is, the time of wishing on is 0.4 second to 0.5 second.What further, more wish is to change (because the amount of washings is many more, impeller is difficult to rotation more, so will prolong the time of on) the running time limit according to the amount of washings 50.
High concentration detergent liquid is soaked into.Soaking into of high concentration detergent liquid undertaken by the prolongation of detergent dissolution operation.Utilize the effect of pump of the interior impeller 6a of impeller 6, positive and reverse return that will be by impeller 6 then the high concentration detergent liquid that generates supply in the washing and dewatering groove 5.The supply method of relevant high concentration detergent liquid uses Fig. 7, is elaborated.If make impeller 6 rotation, the then interior impeller 6a of impeller 6 effect that produces centrifugal pump, the high concentration detergent liquid that will remain in (bottom) between washing and dewatering groove 5 and the water jacket 4 is drawn onto in the gap 10 from the water inlet 5c of the bottom of washing and dewatering groove 5.Like this, high concentration detergent liquid, is discharged in the washing and dewatering groove 5 from outlet 8b in peripheral passage 8 from the washing agent liquid inlet 8c of the peripheral passage 8 of the bottom that is positioned at washing and dewatering groove 5, begins to soak into washings 50 from the side of washings 50.Further, high concentration detergent liquid also is ejected in the washing and dewatering groove 5 from a plurality of hole 6b or the gap on impeller 6 peripheries that is arranged on the impeller 6, soaks into washings 50 from the below of washings 50.In addition, impeller 6 for enlarge covering the most big footpath circumference of bottom gradually, and is the dish shape form that is bent upwards as mentioned above.Therefore, because the rotation of impeller 6, the washings on the impeller also rotates with impeller.In view of the above, high concentration detergent liquid soaks into washings 50 many times from the side and the below of washings 50.The high concentration detergent liquid of about 5-8 times of concentration of the concentration (1 times) of suitable washing and the washing agent liquid phase ratio of 1 times of concentration, wetting-out rate want big 3-4 doubly, can soak into the whole of washings 50 soon.Like this, the chemical washing power of high concentration detergent liquid (soaking into emulsification, the effect of dispersion etc.) acts on attached to the spot on the washings 50, is to be easy to the state of spot from washings 50 removings.
This high concentration detergent liquid soak into operation, comprise the detergent dissolution operation of step 105, the positive and negative rotational time that only needs impeller 6 is just enough about 30 seconds to 1 minute, preferably the amount of washings 50 is many more, wants time expand more.
Open water supply electromagnetic valve 17b, begin to supply with running water.The water supply of these washings until proceeding to the determined water yield in step 102, in the way of supplying water, is interrupted for the cloth amount (wet cloth value) that detects washings 50, cloth matter.This interruption water level is to be set in advance in the wet cloth cloth amount of suitable detection in the micro computer 25 and the water level of cloth matter.In addition, interrupting between the water supply of water level to this, the concentration of high concentration detergent liquid reduces gradually.Also can make impeller 6 positive and negative rotations (the running time limit can be identical with the detergent dissolution operation) therebetween.So, in high concentration detergent liquid, mechanical force can act on washings 50 (because the water yield is few, so be near the impeller 6 washings), has improved cleaning strength.
Detect wet cloth cloth amount and cloth matter, carry out the correction of washings output and determining of washing procedure (washing procedure and rinsing process).The detection of this cloth matter is the low water level interruption water supply fixed, the electric operating clutch mechanism 7b of drive unit 7 is controlled at stir mode, at short notice, 7a energizes to drive motors, rotation drives impeller 6, the 1st deceleration characteristic (wet cloth cloth amount) in the inertia rotation of detection when discharging is followed, once more water supply start, with the washings supply arrive behind the fixed high water level, interrupt supplying water, at short notice, 7a energizes to drive motors, rotation drives impeller 6, the 2nd deceleration characteristic in the inertia rotation of detection when discharging, poor according to the 1st attenuation characteristic and the 2nd attenuation characteristic detects the cloth matter of washings 50.This cloth quality inspection observing and controlling system is being omitted when not required by initial setting.Like this, according to cloth matter, determine time and current (mechanical agitation intensity) in washing and rinsing process.
Supply with running water until the determined water yield (water level) in step 102.By this water supply, washings diluting high-concentration washing agent liquid is the detergent concentration (1 times) of suitable washing.In view of the above, washings 50 is the state in the washings that are immersed in detergent concentration (1 times) fixed in the washing and dewatering groove 5.
Opening water discharge electromagnetic valve 13a is discharged to washings outside the machine.Like this, the electric operating clutch mechanism 7b of drive unit 7 is controlled to dehydration mode,, the washings on the washings 50 are carried out centrifugal dehydration because high speed rotary drive motor 7b rotates at a high speed by making washing and dewatering groove 5 and impeller 6 one.
Open water supply electromagnetic valve 17b, supply with rinse water (running water) until setting the water yield.
Opening water discharge electromagnetic valve 13a is discharged to rinse water outside the machine.
Under the state of opening water discharge electromagnetic valve 13a, the electric operating clutch mechanism 7b of drive unit 7 is controlled to dehydration mode, because high speed rotary drive motor 7b rotates at a high speed by making washing and dewatering groove 5 and impeller 6 one, and the moisture on the washings 50 is carried out centrifugal dehydration.After the centrifugal dehydration of carrying out being fixed time, finish washing.
According to the present invention, can generate high concentration detergent liquid with comparalive ease, can become the washing machine of the cleaning strength that improves the clothing class.
