Description
Technical field
The present invention relates to washing machine, particularly relate to a kind of be immersed in washing clothes in the high concentration detergent liquid in the washing and dewatering tube after, the washing procedure that supplies water again, can improve the washing machine of the ability of cleaning.
Background technology
In common automatic washing machine structure, all carry out work: detect the amount that drops into the washing clothes in the washing and dewatering tube according to following operation; Drop into washing agent with the laundry amount respective amount; In washing procedure, according to the running water (washings) of laundry amount supply respective amount afterwards, agitator arm is rotated to positive and negative direction, perhaps, the washing and dewatering tube is rotated to a direction, or it is rotated to positive and negative direction, and institute's washing clothes is applied mechanical force; Then, carry out matting, in supply running water (rinse water), institute's washing clothes is similarly applied mechanical force; Then, rotate, carry out dehydration procedure, dewater with the rinse water that the method for centrifugal dehydration makes in the washing clothes to be contained by making the washing and dewatering tube.Again, in institute's washing clothes being carried out dry scrubbing-and-drying unit, carry out the heated-air drying operation, clothing is dried up with hot blast.
In this automatic washing machine and scrubbing-and-drying unit, in washing procedure, be dissolved in the amount of the synthetic detergent in the washings, generally be that the concentration of washing agent is about 0.07% in the washings about 20g/30L (detergent amount/washing water yield).
When the washings with this detergent concentration wash, because the clean ability chemically of washing agent is not too big, in order to remove attached to the dirt on institute's washing clothes, just must strengthen the revolving force of the agitator arm of washing machine, the perhaps revolving force of washing and dewatering tube, perhaps prolong the time of washing, with the mechanical force of booster action on washing clothes.As a result, realistic situation is to exist or the damage to washing clothes that causes because of mechanical force sharply increases, and perhaps the winding of institute's washing clothes increases.
And when the winding of washing clothes increased, the agglomerating one-tenth piece of washing increased, and it is difficult that the taking-up of washing clothes all becomes.In addition, in scrubbing-and-drying unit, the heated-air drying in the washing and dewatering groove is owing to the generation of agglomerating one-tenth piece becomes difficult, and perhaps fold appears in washing clothes.Must reduce to act on the mechanical force of washing clothes in order to carry out heated-air drying, thereby reduce the winding of clothing, its result produces the problem that the decontamination situation worsens.
Therefore, in the past in order to reduce in washing procedure, to act on the mechanical force on the washing clothes, proposed before washing procedure, increase in advance institute's washing clothes is immersed in preimpregnation operation in the high concentration detergent liquid, (for example, see also patent documentation 1, Japanese kokai publication hei 7-80182 communique by means of the automatic washing machine scheme of utilizing high concentration detergent to improve the clean ability of chemistry, the 5th page, Fig. 1).
Disclosed example is in patent documentation 1, as the preimpregnation operation, is when the washing and dewatering tube rotates, and the cleaning solution of high concentration is sprinkled upon on the washing clothes.At this moment, the cleaning solution of high concentration is just owing to centrifugal force has soaked into washing clothes.
, the user at random drops into washing clothes in the washing and dewatering tube, and institute's washing clothes not necessarily is in poised state in tube.Like this, because the washing clothes imbalance just can not make the washing and dewatering tube rotate with sufficiently high rotating speed, the situation that high concentration detergent liquid does not fully soak into washing clothes appears sometimes in above-mentioned preimpregnation operation.
In addition, because high concentration detergent liquid under in washing and dewatering tube rotating process, spilling, cleaning solution will produce foam, because the resistance of this foam also has to make the washing and dewatering tube can allow cleaning solution pass through the situation (particularly under the situation that the amount of institute's washing clothes is a lot) of the high like that speed rotation of washing clothes.
Summary of the invention
The present invention puts forward in view of these problems, its objective is that providing a kind of can spill cloth to the cleaning solution of high concentration on washing clothes equably, it is soaked into, thereby improve the washing machine of its clean ability.
For achieving the above object, washing machine of the present invention is after soaking into the washing clothes in the washing and dewatering tube in high concentration detergent liquid, supply water again and carry out the washing machine of washing procedure, it is characterized in that it has the control device that following various operations are controlled:
In washing dissolving water, the high concentration detergent liquid that forms high concentration detergent liquid forms operation with detergent dissolution;
When above-mentioned high concentration detergent liquid is diluted, make its distribution and be soaked in the operation of soaking in the washing clothes;
Above-mentioned soak into operation after, with the pre-wash operation of mechanical force on washing clothes; And
After above-mentioned pre-wash operation, the necessary water yield of supply washing, in formed washings with the washing procedure of mechanical force on washing clothes.
Here, above-mentioned control device in the pre-wash operation, by means of in the washing and dewatering tube the agitator arm of mechanical force on washing clothes and the relative motion of washing and dewatering tube, make its rotation or stirring thereby washing clothes controlled.Utilize this course of work, just can fully soak into institute's washing clothes, to improve the clean ability of washing machine with high concentration detergent liquid.

Fig. 4 is the block diagram of the electric formation of this scrubbing-and-drying unit of expression.
Among Fig. 4, control assembly 16 is to be the control section of the scrubbing-and-drying unit that constitutes of center with microcomputer 16a, carries out work by the electric power by the power circuit 16b supply of source power supply power supply.Microcomputer 16a is connected on input switch group 14a and level sensor 15, humidity sensor 40, first and second temperature sensors 41 and 42, uneven detecting sensor 43 and the cover switch 44, and it accepts the signal of following various information: the signal of the signal of water level, the temperature and humidity in the decline air channel 25 etc. in the signal of user's action button, the washing and dewatering tube 2.Supply with drive circuit 16c from the signal of microcomputer 16a output, and source power supply supplied with following each several part, and control the switch or the rotation of these parts: main electromagnetism feed water valve 20, auxiliary selenoid feed water valve 22 and 22a, cooling watering electromagnetic valve 24a, drain solenoid valve 33, washing agent stir motor 39, circulating fan 26 etc.In addition, in order to allow the user understand the operation of scrubbing-and-drying unit, it also controls display element group 14b, to show ongoing operation.
The input switch group 14a of guidance panel 14 has following various switch: set washing operation (standard, wash by force, a little less than wash, drying, manual operations, bed clothes etc.) switch; Set the switch of drying process process (standard, shirt, fine finishining, drying etc.); From washing under the situation that drying carries out continuously, set the switch of washing drying process process (standard, shirt, woollen or the like); Set the switch of wash conditions such as wash time and dewatering time, the water yield, rinsing number of times.
Be connected after 70 pairs of source power supplies of bridge commutating circuit on the source power supply carry out full-wave rectification, be entered into that double as improves power factor (PF) and the DC-DC change-over circuit 72 of the usefulness of boosting in.Semiconductor elements such as DC-DC change-over circuit 72 usefulness IGBT are modulated this commutating voltage, and when improving the power factor (PF) of common source, later direct current power supply is given PWM negater circuit 65 boosting.This output voltage is variable, is used to control from the load of the driving square wave of the semiconductor element of microcomputer 16a output.PWM negater circuit 65 produces three-phase RWM square-wave voltage from above-mentioned DC voltage, so that be carried in drive motors, promptly on the DC brushless motor 61, makes its rotation.Hall element 61a as the checkout gear of rotor-position is housed in DC brushless motor 61 inside.Detect after the position of rotor with this Hall element 61a, it is delivered among the microcomputer 16a.Then, microcomputer 16a is just according to the position of this rotor, information such as rotary speed, the rotating speed and the direction of rotation of control DC brushless motor 61.
Below, the course of work of the above-mentioned various operations of the scrubbing-and-drying unit with this structure is described.Fig. 5 is the flow chart of above-mentioned each operation of being carried out of the microcomputer 16a in the control assembly 16.
During beginning wash button switch in pressing input switch group 14a, microcomputer 16a just carries out following various control to be handled.
Step 401
When the user drops into washing clothes 38 in the washing and dewatering tubes 2, the input switch group 14a on the operating operation panel 14 carries out initial setting, and when depressing the press button that begins to wash, and microcomputer 16a just begins to carry out the control of the automatic running of each operation to be handled.
In above-mentioned initial setting, set the washing operation that adapts with washing clothes, as required, also to set time, the water yield of time of washing and dehydration, number of times of rinsing etc.Also have, after washing, also will carry out under the dry situation, set the dry operating process of washing.
Carrying out the detection control of washing clothes 38 laundry amounts in step 402 handles.This clothes amount detection, be under the drying thing state before water supply, the electric operating clutch mechanism 62 of drive unit 6 is controlled to be stir mode, carry out the short time energising to drive motors 61, driving agitator arm 4 rotates, accelerating performance during according to the rotation speedup perhaps ought stop to drive motors 61 power supplies, and the deceleration characteristic when inertia rotates detects.According to this testing result (laundry amounts of washing clothes), calculate to determine the water yield of washings and be the amount of the washing agent of the washings that form desirable detergent concentration, and show the amount of this washing agent by display element group 14b.The user pulls out washing agent pallet 73 with reference to shown detergent amount, adds the powder synthetic detergent, the washing agent pallet is pushed in again, and the powder synthetic detergent is fallen in the detergent dissolution container 21.
In step 403, form high concentration detergent liquid.In the time of in detecting, just open auxiliary water supply electromagnetic valve 22, be supplied to detergent dissolution container 21 being unlikely a spot of running water (water of dissolving detergent) that overflows powder synthetic detergent input detergent dissolution container 21.Then,, drive agitator arm and rotate, in the powder synthetic detergent in agitator treating agent dissolution vessel 21, make its dissolving, form high concentration detergent liquid to 39 power supplies of wash agitation motor.
The water yield of detergent dissolution water, different along with the amount of the powder synthetic detergent of the capacity (size) of employed detergent dissolution container 21 and washing usefulness, but must be that the powder synthetic detergent is dissolved fully, and in whipping process, not take place from the water yield of the 21a of spilling water portion spilling water.For example, when the capacity of detergent dissolution container 21 was 500mL (capacity till the spilling water part is 400mL), the water yield that can set detergent dissolution water was 150～200mL.The water yield of detergent dissolution water is controlled by the duration of valve opening of auxiliary water supply electromagnetic valve 22.The concentration of formed high concentration detergent liquid also has nothing in common with each other along with the difference that drops into the detergent amount (amount of washing clothes, the amount of washings) in the detergent dissolution container 21.For example, washing capacity is that the amount of washings of scrubbing-and-drying unit of 8kg is about 24～68L, so high concentration detergent liquid should be 80～500 times of detergent concentration of washings.
Dissolution time needs 2～3 minutes.Because dissolution time is different along with the kind of powder synthetic detergent, but even not diffluent washing agent, in 2～3 minutes, its dissolution rate also can reach 95～100%, so in 2～3 minutes, can dissolve the washing agent of the overwhelming majority.
The electric operating clutch 62 of accessory drive 6, make it be in dehydration and drying mode, make drive motors 61 carry out low-speed running, when washing and dewatering tube 2 and agitator arm 4 are slowly run, open main water supply electromagnetic valve 20, directly to feed water inlet 19 supply running water, and with these running water as the pre-supply water that is dispersed on the interior washing clothes 38 of washing and dewatering tube 2.The water yield of pre-supply water is the water yield (4～10L) of the uppermost several clothings of the moistening washing clothes of energy at least.When scattering high concentration detergent liquid afterwards, supply water in advance when promoting that high concentration detergent liquid soaks into washing clothes 38, can also prevent the look class that fluorescent whitening agent that washing agent contains may cause.
This pre-water supply operation is carried out in the formation high concentration detergent liquid operation of step 403.This point as mentioned above, is because the dissolving of washing agent needs 2～3 minutes time, and the operation that supplies water in advance in the middle of this just can shorten wash time.
The electric operating clutch 62 of accessory drive 6, make it be in dehydration and drying mode, make drive motors 61 carry out low-speed running, when washing and dewatering tube 2 and agitator arm 4 are slowly run, open auxiliary water supply electromagnetic valve 22, by supplying dilution waters, diluting high-concentration washing agent liquid to detergent dissolution container 21, by means of from spilling water part 21a spilling water, send in the water filling port 19.Simultaneously, open main water supply electromagnetic valve 20, supply water to water filling port 19, high concentration detergent liquid is diluted to desirable high concentration detergent liquid (5～20 times), this high concentration detergent liquid is sprayed on the interior washing clothes 38 of washing and dewatering tube 2 from the aperture 19c of aproll lid 19b in the mode of spray again, and it is soaked into.Because the washing clothes 38 in washing and dewatering tube 2 rotates with washing and dewatering tube 2, so high concentration detergent liquid can fall equably and soak into washing clothes 38.
Because high concentration detergent liquid has soaked into washing clothes 38, the chemistry of high concentration detergent liquid is cleaned ability (soak into, effect such as emulsification, dispersion) just to working attached to the dirt on the washing clothes, dirt is in be easy to the state of removing from washing clothes.
When scattering high concentration detergent liquid, the electric operating clutch 62 of drive unit 6 is controlled at washing mode, so that carry out positive and negative running repeatedly by means of drive motors 61, make washing and dewatering tube 2 and agitator arm 4 carry out forward and backward repeatedly in the opposite direction, stir.
Washing clothes 38 along circumferencial direction counter-rotating repeatedly, becomes the rotation of above-below direction gradually on agitator arm 4 when high concentration detergent liquid begins to soak into it from top.This be because, high concentration detergent liquid is contained on the top of washing clothes 38, and is heavier, and the bottom is dry, low weight, washing clothes is stirred the inertia force of impeller 4 when counter-rotating and has reversed.Because agitator arm 4 is in the very big bowl-shape state that is carrying whole washing clothes 38 of diameter, so the inertia force of agitator arm 4 when counter-rotating can work effectively, can carry out switching of washing clothes expeditiously.In addition, when carrying out this course of work,, also needn't worry to produce the possibility of clothing local damage though the mechanical force of agitator arm 4 partly acts on the washing clothes with the little agitator arm 4 of diameter.
In such process, because washing clothes is switched, lighter (drying) part in bottom is switched to top has come, and high concentration detergent liquid is sprinkled upon on the dry part, thereby can scatter high concentration detergent liquid equably expeditiously.Further, owing to stir, make the relative position relation of each part washing clothes 38 that some all take place and change, thereby have with rubbing and wash same effect, can strip down dirt from washing clothes 38.
In addition, be right after after beginning to scatter high concentration detergent liquid, can prolong, and shorten the time (0.4～0.8 second) of cutting off the power supply to the time (about 1～2 second) of drive motors 61 energisings.Perhaps, also can improve the energising voltage of drive motors 61.Like this, strengthened the activity of washing clothes 38 on circumferencial direction and above-below direction, can scatter high concentration detergent liquid equably and be soaked on the washing clothes 38 at short notice.When the distribution of high concentration detergent liquid is proceeded, make washing clothes 38 because of contain a lot of cleaning solutions become very heavy after, just shorten to the time (about 0.4～0.8 second) of drive motors 61 energising, perhaps reduce the voltage of energising, carry out weak stirring, thereby prevent the winding of clothing.But even if weak stirring, the relative position of washing clothes 38 still changes, and owing to the gap between the washing clothes is constantly changing, thereby can obtain the effect that high concentration detergent liquid soaks into washing clothes equably.
When level sensor 15 detects water level and is higher than agitator arm 4 a little, just close main water supply electromagnetic valve 20.At this output constantly approximately is 10～20L (different with the amount of washing clothes), be dispersed in the high concentration detergent liquid of 5～10 times of concentration in the washing clothes 38, when soaking into washing clothes, also accumulate in the urceolus 5, supply water through main feed water valve, be diluted to the state of about 3～4 times of concentration.
Then, the electric operating clutch 62 of control accessory drive 6, make it be in washing mode, positive and negative rotation repeatedly by means of drive motors 61, make washing and dewatering tube 2 carry out positive and negative rotation repeatedly towards opposite direction with agitator arm 4, make washing clothes 38 swings (rotate or stir), carry out first pre-wash.
In this first pre-wash operation, carry out repeatedly to the time ratio washing procedure of drive motors 61 energisings short (different with the amount of washing clothes, as for example, to be 0.4～0.8 second), and its longer counter-rotating of the time ratio that stops to switch on.That is, adopt, can swing the washing clothes 38 that has soaked into high concentration detergent liquid expeditiously,, dirt is floated up from washing clothes 38 by means of rubbing cleaning function than the stirring a little less than the washing procedure.
In addition, also has such effect, promptly, utilize the pump-absorb action of the intra vane 4b of agitator arm 4, the high concentration detergent liquid that accumulates in urceolus 5 bottoms, from the water hole 4a of agitator arm 4 and the gap on the excircle part, pump is drawn onto in the washing and dewatering tube 2, scatters to be supplied to the bottom that washing agent liquid is difficult to arrive when the scattering high concentration detergent liquid washing clothes 38 of (near agitator arm 4).
In addition, it is large diameter bowl-shape that agitator arm 4 is, will be roughly all washing clothes 38 all mounting under the state on the agitator arm 4, can make whole washing clothes 38 all produce motion, because the conduction time of stirring is very short, can suppress the relative velocity between agitator arm 4 and the washing clothes 38 very little, so, even few like this water yield, the damage and the winding that also can not produce clothing basically.
In addition, the electric operating clutch 62 of drive unit 6 is controlled at stir mode,, also can obtains same effect even make agitator arm 4 counter-rotatings like that according to above mode.But, because the water yield is less, the reaction force that agitator arm 4 rotates can make urceolus 5 swing significantly and collide outside framework 1, because of becoming the reason of generation noise, so, had better be controlled at washing mode to electric operating clutch 62.
In above statement, be to close main water supply electromagnetic valve 20, carry out again after stopping to supply water first in advance the washing, but, also can under the state of opening main water supply electromagnetic valve 20, carry out first in advance the washing.Like this, just can prevent that wash time from extending to more than the necessary time.
But, very high at the hydraulic pressure of running water, under the very big situation of water supply flow, the time of first washing in advance is just too short.Therefore, open and close master water supply electromagnetic valve 20 shortens the time that main water supply electromagnetic valve 20 is opened, to reduce average output when water supply flow big (the hydraulic pressure height of running water) repeatedly.Like this, just can make the time of first washing in advance keep constant, and irrelevant with the hydraulic pressure of running water.
Step 407
Open main water supply electromagnetic valve 20 and auxiliary water supply electromagnetic valve 22, begin to supply running water (washings).The water supply of this washings generally proceeds in the step 402 till the determined water yield, but owing to the laundry amounts that detects washing clothes 38 in water supply process (numerical value of wet cloth), clothing quality are interrupted.This interrupts water level, is divided into the first clothing quality sensed water level and second clothing two stages of sensed water level directly.In addition, auxiliary water supply electromagnetic valve 22 is to open when cleaning detergent dissolution container 21.The first clothing directly concentration of the washing agent liquid of sensed water level approximately is 2 times.
Directly the wet laundry amounts on the sensed water level and clothing be directly to detect first clothing.The detection directly of this clothing, to be controlled at stir mode or washing mode to the electric operating clutch 62 of drive unit 6, to the power supply of 61 short time of drive motors, drive agitator arm 4 and rotate, detect first deceleration characteristic (wet laundry amounts) that the inertia after outage rotates.
Water supply start once more, water add to second interrupt water level till.Washings supply water near washing comparatively ideal detergent concentration (a times) from the detergent concentration water supply start dilution of about twice.In the time of with water supply start, the electric operating clutch 62 of drive unit 6 is controlled at washing mode, by means of drive motors 61 repeatedly to the running of positive and negative direction, make washing and dewatering tube 2 and agitator arm 4 carry out positive and negative rotation repeatedly in the opposite direction, thereby make washing clothes 38 swings, carry out second washing in advance.
In this second washing in advance, owing to be under the state that the water yield that the water yield is determined in than second step 402 is lacked, to stir, so the positive and negative cycle turnover of stirring can be than washing procedure short (that is, short than washing procedure to the conduction time of drive motors 61).Like this, not only can reduce the winding of clothing and the damage of clothing, the cleaning function of rubbing that can also utilize the swing because of washing clothes 38 to produce improves clean ability.
And then, because the whole basically mountings of washing clothes 38 are utilized the friction of the wall of washing clothes 38 and washing and dewatering tube 2 on large diameter bowl-shape agitator arm 4, also can improve the ability that it is cleaned.
In addition, second washing in advance be in the past detergent powder is sprinkled upon the mode of washing that washing machine was carried out on the washing clothes with original state., mode in the past is in moment of washing in advance, and a part of pulverous washing agent is not dissolving also, thus the concentration ratio of washing agent liquid with the detergent amount that drops into the concentration that calculates of the watermeter of confession low.Therefore, mostly can not as improve its clean ability expecting.In contrast, in the present invention, washing agent has dissolved fully, is that the situation of powder original state is compared with the washing agent that drops into, and can wash in advance with higher washing agent liquid concentration, and its direct result has improved the clean ability of washing in advance.
In addition, the hydraulic pressure control water supply flow (when the hydraulic pressure of running water is high, carrying out intermittent water application, to reduce the flow that supplies water) according to running water can make the time of second washing in advance constant.Like this, no matter the height of the hydraulic pressure of running water can both obtain roughly the same clean ability.
In addition, second washing in advance also can be carried out under the state that stops to supply water after step 408.Like this, can under higher concentration, wash in advance, can improve the ability of cleaning.
Second washing in advance at the latest will reach second clothing directly before the sensed water level some times finish.This is because when washing in advance, the water surface in the urceolus 5 fluctuates, and can not detect correct water level with level sensor 15.
When reaching second clothing directly during sensed water level, main water supply electromagnetic valve 20 is closed, to detect the wet laundry amounts and the quality of clothing.With with step 408 in the similar detection method, detect second deceleration characteristic (wet laundry amounts).
According to the difference of first deceleration characteristic and second deceleration characteristic, the clothing of detection washing clothes 38 directly.Then,, determine time and the current (churned mechanically intensity) and the dewatering time of washing and rinsing process according to the quality of laundry amounts and clothing, and the control constant during dry operating.When the clothing in needs step 408 and this step does not directly detect control according to initial setting, can omit these steps.
The supply running water, the determined water yield (water level) in reaching step 402.By above-mentioned water supply, washings just reach the detergent concentration (a times) that is suitable for washing.Like this, washing clothes 38 just is in washing and dewatering tube 2 under the state in the washings of the detergent concentration (a times) that is immersed in regulation.
Here, relatively describing with regard to clean ability of the present invention and clothing winding rate and method of cleaning in the past.The condition of test is: use the scrubbing-and-drying unit of washing capacity as 8kg; The amount of washing clothes is 4.8kg; Washing agent is commercially available powder synthetic detergent (detergent amount of washing agent producer recommendation is 20g/30L); Water temperature is 20 ℃, and hardness of water is that 50ppm (is converted into CaCO
3); Wash time is 7 minutes.
Fig. 6 represents the comparison of the ability of cleaning.If with do not wash in advance 1 and the clean ability of washing in advance under 2 the situation be 1, then carry out cleaning in advance 1 and can improve the ability 8% of cleaning, carry out in advance cleaning 2 and can improve clean ability 13%, wash 1 and wash 2 boths in advance when carrying out in advance, can improve clean ability 20%.Following situation can be used as reference, will improve by the method that prolongs wash time (only relying on mechanical force) and clean ability 20%, then needs wash time is extended to three times.
Fig. 7 represents the comparison of clothing winding rate.To twine calibration will be 1 if will not carry out clothing under the washing situation in advance, wash 1 and wash 2 boths in advance when carrying out in advance, and clothing winding rate is increase by 10% approximately., for obtaining same clean ability, prolonging under 20 minutes the situation of wash time, clothing winding rate approximately will increase by 60%.
Like this, by soaked into washing clothes with high concentration detergent liquid after, wash in advance again, can reduce clothing winding rate, can improve clean ability again.
