Convertor circuit 71 makes dc source with the power frequency supply rectification after level and smooth, inverter circuit 72 makes 3 cross streams power supplys to this dc source, three-phase alternating current is supplied with three phase induction motor inverter circuit 72 to be made of IGBT module 73 and pwm signal circuit 74, additional pwm signal on the door terminal of IGBT, behind the copped wave dc source each UVW coil of 3 cross streams electric current supply three phase induction motors 7.Pwm signal circuit 74 is connected with microcomputer 50, makes frequency that indication according to microcomputer decides the three-phase alternating current of supplying with three phase induction motor and voltage or each UVW pwm signal of phase relation mutually.Fig. 6 (b) represents the parts around the inverter circuit 72 in detail.If UVW becomes the phase relation of 120 degree successively, then three phase induction motor for example makes VW to reverse by counter clockwise direction with above-mentioned opposite phases relation by turning clockwise.
The following describes operating process according to the deionizer 28 of embodiment.
In the present embodiment, the user puts into washtub 5 with washings, press power switch 19, one operation standard wash button 80 or the high wash button 81 of cleaning, microcomputer is just measured the washings amount according to the cloth quantity sensor, expression is according to the water yield, the detergent amount of measurement result on display 21, and the user can be known thus.The user drops into an amount of washing agent of the reference of expressing in the washtub 5.Microcomputer is opened water supply electromagnetic valve 27 afterwards.Running water by water supply electromagnetic valve 27, is flow into the bottom compartment 60c of cylindrical vessel 60 from water tap mouth 26 by water inlet 29a.After the running water that flows into is full of bottom compartment 60c, rise to chamber 29e under this pressure, running water flows out among the upper chambers 60b then by clamping between the sodium type storng-acid cation exchange resin 31 of filling with net-type filter 29d in the 29e of chamber.Flow out from delivery port 29b after being full of upper chambers 60b, be stored in outer bucket 4 (washtubs 5) by chamber A47, inclination road 46.And the part of running water that flows to bottom compartment 60c is by ion exchange resin 31, but flows in outer barrel 4 by the salt solution drainpipe that is connected with salt solution outlet 29c.If the internal diameter of salt solution outlet 29c is 2mm, then the flow that is 15/ timesharing by discharge pipe 64 at water supply flow is about the 0.5L/ branch.This amount is 3% of an output, influences very little.If the internal diameter of salt solution outlet 29c is littler, then influence is littler, because capillarity is difficult to discharge the salt solution of regeneration usefulness, so above-mentioned 2mm is optimum.If there is not the problem in cost and space, then in the way of salt water discharge pipe 64, valve is set, valve-off in water supply process, the advantage of such method is self-evident.
When running water passed through ion exchange resin 31, calcium, the magnesium ion that will wherein contain in ion exchange were removed.The bright lamp of light emitting diode in this washing water supply process, with soft waterization represent 24 or buzzer 23 be illustrated in ion and remove in the process or report.In the water supply process, the upper chambers 60b of ion interchange unit 28 is full of with running water, clogs hole 60e because the spheroid of this pressure check valve 60f rises.Therefore, running water can not enter brine chamber 60k in water supply process.When supplying water, because the air pressure of upper chambers 60b is atmospheric pressure, because of the spheroid of gravity check-valves 60f falls, hole 60e is open state.
The following describes the high wash button 81 of cleaning, the situation of the washings that the washing spot is serious pressed.Microcomputer 50 knows that according to level sensor 11 washings of ormal weight have supplied water in the outer bucket 4, stop to supply water so close water supply electromagnetic valve 27.And in order to make the just contrary rotation of rotor 6, output makes the three phase mains of setpoint frequency, voltage, phase relation be interrupted the information of supplying with three phase induction motor 7 in pwm signal circuit 74.Consequently, the just contrary rotation of rotor 6 beginnings, washing beginning.At this moment, begin washing if press the high wash button 81 of cleaning, the frequency ratio of the three phase mains of setting is in that to press the frequency that sets when wash button 80 is washed higher.
Resemble known the revolution and the incoming frequency of induction conductivity proportional.The rotary speed and its frequency that are the rotor 6 that drives of induction conductivity are proportional.Frequency setting when for example pressing standard wash button 80 is 50Hz, if the rotating vane rotary speed is 110rpm, is set at 68Hz if press when height is cleaned wash button 81, and then the rotor rotary speed is 150rpm.But generally in order to keep certain voltage and frequency ratio and to produce much at one moment of torsion revolution characteristic, so if wish the frequency increase then voltage also increases.
The washtub 5 interior washings that supply water do not contain CATION such as calcium, magnesium, generate metallic soap alkali so can not react with the surfactant in the washing agent that drops into.Thereby can not cause making the amount of surfactant that is of value to clean to reduce to make washability to reduce.After supply water finishing, residual water slowly are discharged to outer barrel 4 from the salt water discharge pipe 64 that links with salt solution outlet 29c in the ion interchange unit 28.
Above-mentioned result is that in the slurry during washing in washtub, the chemical force of surfactant increases.And the rotary speed of rotor set for the state that is increased to 150rpm from the 110rpm of standard wash.And in the slurry of dissolving detergent, washings is stirred and cleans.Because of this chemical force increases and the synergy of the mechanical force that accompanying rotation speed increases, obtain the described high washability in back.
Sodium type storng-acid cation exchange resin 31 is as known, on the macromolecule matrix of crosslinked three-dimensional, with chemical bond in conjunction with as the synthetic resin that forms of sulfonic ion-exchange group.Contain the cationic running water one of divalent such as calcium, magnesium and flow through between the ion exchange resin, as the sulfonic group of the ion-exchange group of ion exchange resin just with running water in cation exchange, the result removes the CATION in the running water.Chemical formula 1, Chemical formula 2 are represented the ion-exchange reactions formula of sodium type highly acid exchanger resin.
Here, R is the macromolecule matrix of ion exchange resin.Because sodium type ion exchange resin makes-SO
3Anion become fixed ion, make the CATION of Na become the coupling ion, so polyvalent cations such as the calcium that contains in utilizing the selectivity of ion to remove to anhydrate, magnesium.When using storng-acid cation exchange resin under low concentration, normal temperature, ion its ion selectivity high to valence state is big, and ion its ion selectivity big to same valence state atomic number is big.The ion that contains in natural water is the order of chemical formula 3.
Na
+＜K
+＜Mg
2+＜Ca
2+
By the calcium in the water of ion exchange resin, magnesium ion according to the reaction from the left side to the right of Chemical formula 1, Chemical formula 2 by the resin sorption and remove.In the salt solution one of opposite high concentration the has flow into sorption resin of calcium, magnesium ion, then according to Chemical formula 1, Chemical formula 2 reaction desorb calcium, the magnesium ion from the right to the left side, resin is got back to original state and is reproduced.
The commercially available small-sized soft water makeup of using in the laboratory is put, and general ion exchange resin amount is 1-2L, handles per hour 10L (per minute 0.16L) of flow.In above-mentioned home-use washing machine, in order to shorten water supply time, directly supply water washtub with the flow more than the per minute 10L from water tap in.Because its water supply time of processing flow that above-mentioned commercially available small-sized soft water makeup is put is long,, make the water of batch processing be stored in water butt utilization more later on so have to utilize the washing time in addition.And ion exchange resin amount 1-2L, then volume is excessive in home-use washing machine to load (built-in).That is to say that the home laundry machine need solve the problem of above-mentioned TREATMENT OF ION EXCHANGE RESINS flow, amount of resin.
According to the running water that carries out in the past statistics, in the number of packages of investigation, the number of packages of total hardness below 40ppm is half of sum in Japan, and the number of packages that surpasses 100ppm accounts for 15%, addition average is 54.5ppm.
Among Fig. 7, the expression hardness of purifying waste water in Japan distributes (equalling into 6 years running water statistics from what Japan Water Works Association announced), and when using the commercially available synthetic detergent that adds small-sized zeolite, with detergent concentration as the clean rate of parameter and the relation of hardness.Hardness distribute to be considered the purification water yield of purifying waste water an every day, for example as can be known about 20% of the gross decontamination water yield between 40-50ppm.The purification water yield of field and family is proportional if respectively purify waste water, then the running water of 20% of total family use 40-50ppm.The average hardness in the whole nation is 52.9ppm, and overall 98% below 100ppm.For clean rate, when detergent manufacturers is specified the detergent concentration 0.067wt% (weight %) of detergent amount,, the average hardness 52.9ppm that reduces by half increases about 50% more than because of can making the rate of cleaning.And hardness makes it reduce by half when 100ppm can to obtain with the identical clean rate of 2 times of detergent amounts (concentration 0.133wt%).Be that the clean rate of detergent amount (concentration) when being 2 times of standard can descend in hardness, obtain under standard wash dosage.Remove such hardness components calcium ion, magnesium ion and can improve the washability of washing machine greatly.And if obtain clean rate identical when in statu quo using running water, then can be by the consumption of soft water minimizing washing agent.Further, the detergent amount that uses in the area more than the 40ppm in hardness need not more than necessary amount, and the influence of environment is also diminished.
As shown in Figure 7, hardness is cleaned rate when 40ppm is following almost be definite value, the rate of cleaning during hardness more than it reduces hardness when 40ppm is following, because the zeolite that contains in the synthetic detergent is almost the whole sorptions of hardness components, surfactant plays one's part to the full, so the rate of cleaning almost be definite value at this more than hardness number because the amount of zeolite deficiency, a part of surfactant and hardness components reaction generation metallic soap alkali.Its part surface activating agent reduces, so the rate of cleaning reduces.Therefore, when using the synthetic detergent that adds zeolite during washing, wish from washings, to remove hardness components calcium ion, magnesium ion, up to 40ppm.On the other hand, different when generating metallic soap alkali with Fig. 7, so preferably remove all hardness components as far as possible because hardness is cleaned the rate reduction when increasing.
The ion-exchange performance of ion exchange resin is by decisions such as ion exchange capacity, ion-exchange speeds.When washing machine makes spent ion exchange resin, as mentioned above, require to handle flow per minute 10-15L, make the amount of resin that in washing machine, may load the least possible.In order to reach this purpose, thereby make ion-exchange speed guarantee to handle flow greatly as far as possible, can reduce amount of resin thereby ion exchange capacity is increased.Ion exchange capacity, ion-exchange speed change along with the degree of cross linking of ion exchange resin, the structure of resin (gel-type, porous) and resin diameter etc.But the ion exchange capacity that the degree of cross linking is high increases, and improve than its ion-exchange speed of gel-type but ion-exchange speed reduces porous type, but ion exchange capacity reduces.Like this, make the degree of cross linking of ion exchange resin and structure two aspect performances improve very difficult simultaneously.
Fig. 8 is, to being used for the sodium type strong-acid ion exchange resin of the degree of cross linking 8% of general use of water softening, with ion exchange resin amount and resin diameter as parameter, the experimental result that changes with respect to the leakage ion concentration of water-flowing amount.The total hardness of former water is 100ppm, and flow is the 15L/ branch.When amount of resin, the resin diameter of experiment, under which kind of situation, all there is hardness components to leak, its concentration is according to amount of resin, resin diameter and difference.In the water flowing initial stage, when the resin diameter was identical, the leakage ion concentration that amount of resin is many was little, and when amount of resin was identical, the leakage ion concentration that the resin diameter is little was little.Fig. 9 is the total surface area (calculated value) with respect to ion exchange resin, the leakage ion concentration of the water flowing initial stage among Fig. 8 is put in order the result of conversion.From figure as can be known, the total surface area of leaking the homo-ion exchanger resin of ion concentration is almost inversely proportional, and the total surface area of ion-exchange speed and ion exchange resin is proportional.So be inversely proportional to and reduce amount of resin by reducing the resin diameter with the ion exchange resin diameter because the total surface area of ion exchange resin is directly proportional with the ion exchange resin amount.Leak the variation of ion concentration, almost remain on finite concentration, but increase gradually, then sharply increase, lose ion-exchange capacity at last and reach and former water concentration together from certain some beginning as if water-flowing amount in the water flowing initial stage.Ion exchange capacity with leaking the area that ion concentration line and former water concentration line surround when amount of resin 100ml, resin diameter 0.1-0.2mm (for example, the area that ABCA surrounds among the figure) expression, but has nothing to do with the resin diameter, and is only proportional with amount of resin.
The ion exchange capacity of the ion exchange resin of Fig. 8 is 2.0meq/mL-R (every 1mL ion exchange resin 2.0 equivalents), with the CaCO of every 1mL resin
3Convert the hardness components that to remove 100mg.Now, consider that the running water of total hardness 100ppm flows with flow 15L/ branch, 1 time water yield 88L of rated capacity 9Kg automatic washing machine high water level is carried out the situation of soft waterization.Soft waterization is if reach the affected 40ppm of washability that does not make the synthetic detergent that adds zeolite, and then the hardness components that should remove is 5.28g (CaCO
3Convert), can be such a small amount of of 5.28mL if only consider the then necessary minimum amount of resin of ion exchange capacity.But, if consider ion-exchange speed then this amount of resin can not make soft waterization reach 40ppm.In fact as Fig. 8, if resin diameter amount of resin when 0.1-0.2mm does not have 100mL, resin diameter amount of resin when 0.3-0.5mm not have 150mL, resin diameter amount of resin when 0.3-1.1mm does not have 260mL, then can not reach below the 40ppm.But, when making the resin diameter be 0.1-0.2m and 0.3-0.5mm, be per minute 15L even handle flow, also can make amount of resin few to 100-150mL, make its loading become possibility at family's washing machine.
Figure 10 is, using resin diameter 0.1-0.2mm, in the deionizer of the ion exchange resin of amount of resin 100mL, divides the leakage ion concentration when flowing through running water (total hardness 100ppm) and the relation of water-flowing amount with flow 15L/.Among the figure ● ion exchange resin was news when symbol was meant first water flowing.Water-flowing amount reaches before the 50L, leaks ion concentration one and concludes a contract or treaty 12ppm, and leaking ion concentration from here on increases, and remains on below the 40ppm but water-flowing amount leaked ion concentration before reaching 100L.Then, water-flowing amount loses ion-exchange capacity when 150L, leaks ion concentration and becomes identical with original water hardness.Therefore, it is necessary handling with the regeneration of above-mentioned salt solution.Handle explanation in the back for this regeneration.The high water level (water yield 88L) of rated capacity 9kg automatic washing machine if supply water, then hardness of washing water becomes the about 18ppm with zero symbolic representation among the figure, and the scourability that does not have to take place to be produced by hardness reduces.
Figure 11 represents with bar chart, is standard (the scourability evaluation assessment of the washing machine of JIS regulation) with existing power frequency supply (50Hz) driven induction motor to the washability of artificial contamination's cloth, turns the washability of the experimental result that is parameter into the slurry soft water behind rotor rotation number, time, the employing deionizer.Compare 1.36 times of (150rpm) (representing with b) that the identical only rotary speed of rotor with a of other conditions is it with standard (rotary speed 110rpm, time 9 minutes, slurry hardness 100ppm, the washability 1 of the rotor of representing with a), then washability becomes 1.25 times.Similarly only the time is its 2 times (18 minutes), and then washability becomes 1.29.Similarly use with deionizer to make hardness reduce by 60% slurry (representing with d), then washability becomes 1.26.Similarly making detergent amount is that detergent concentration is its 1.2 times (representing with e), and then washability is 1.09.
From this result, deionizer to the effect of washing is as can be known, much at one effect when to reach with mechanical force be 2 times of a reference value.And as can be known, increase mechanical forces thereby make the speed of rotor become 1.36 times, thus with make the time become 2 times to increase mechanical forces and produce identical effect for washing.
On the other hand, by housewife overseer's subjective assessment, the result who obtains is, spots such as the flap, sleeve if in the washability of above-mentioned experiment less than 1.6 o'clock, the impression that can not come off for the housewife with spot then.That is to say, this has been illustrated as the solution housewife can not make the flap of shirt, the spot of sleeve come off with existing washing machine, though it is dissatisfied but after the spot part soaked with high concentration detergent and hand-laundering to this, with the situation of washing machine washing, be necessary to make the washability of experiment to reach 1.6 again.
In order to obtain this washability,,, if will make rotary speed identical, must make the time be increased to 3 times so with standard according to the result of Figure 11 iff relying on mechanical force.And, rotary speed is increased be almost 2 times if will make the time identical with standard.
But, increase mechanical force and be related to the damage that increases washings, make the state deteriorating of washings.And because also increase around the cloth phenomenon, washing finishes the back and takes out washings in the washtub and need more strength.The increase noise that is accompanied by rotary speed increases and increases the power consumption that brings by the time and increases.It is very unpractical promptly only depending on mechanical force.
In the present embodiment, the soft waterization that is produced by deionizer improves washability, and the practical rotary speed of rotor becomes 1.3 times, can access to reach about 1.57 washability shown in f among Figure 11.
The soft water effect of slurry has improved the frothing capacity of washing agent.Particularly more remarkable with powdered soap.And it is, slurry is better stirred, thereby better because of promoting the dissolving of air in water to bubble by rotary speed is increased.So washings is surrounded by bubble and be floating, even slurry seldom, the chance of the contact friction between the washings also can increase.Promptly increased the mechanical force that gives washings with a spot of slurry.
In standard wash, if make the detergent amount 37g of water 56L, wash concentration 0.067wt% for washings 5Kg, then clean in the washing for identical washings 5Kg, when water is 45L, can make wash concentration become 1.2 times of 0.08wt% with identical detergent amount 37g at height.Do to access as shown in figure 11 like this, the high washability that washability 1.62% is such.
In the present embodiment as described above, the serious washings of spot is provided with the high washing process of cleaning to being the washings of the 60-70% (about 5Kg) of rated capacity, by slurry soft waterization that produces by deionizer and the rotary speed that increases rotor, can bring into play high washability.
After finishing washing procedure, microcomputer 50 is opened draining valve 13, and the washings in the outer bucket 4 are discharged.Draining forwards dehydration to after finishing.In dehydration procedure, the solenoid 9a of microcomputer 50 control transmission devices 9 makes washtub 5 rotation at a high speed with three phase induction motor 7.Draining valve 13 is being opened during this.
Dehydration procedure is closed draining valve 13 after finishing, and then carries out rinsing process.Rinsing process carries out 1 time to 2 times usually according to its method.In case after water was stored in the outer bucket 4, rotary wing 6 was diluted in washing agent residual on the clothing because this is in rinsing, need with supply water much at one the water yield of former washing.Therefore, by the water yield of deionizer 28, the 88L that supplied water in the washing in the past, amounts to 264L in this rinsing for 88 * 2 times.As shown in figure 10, water-flowing amount loses ion-exchange capacity when 150L, so hardness and former water are same since the way that first time rinsing is supplied water.But, because not influence of hardness in rinsing process, so also it doesn't matter even supply with the high water of hardness.Because the water supply when rinsing process, except that final rinsing process, identical during with washing procedure, so the regeneration of final rinsing process that explanation is here carried out after making water be stored in the outer bucket 4 and the ion regenerating resin 31 that carries out in final rinsing process is handled.At first open water supply electromagnetic valve 27, the same running water that makes with above-mentioned washing procedure passes through deionizer 28, and washings are supplied in the outer bucket 4.Running water is full of the upper chambers 60b of deionizer, and behind the state that check-valves 60f is hole 60e to clog (this judges through the situation of being fixed time according to after opening water supply electromagnetic valve), microcomputer 50 is opened salt water injecting electromagnetic valve 63.Running water flow into salt from salt water filling port 60h, salt water injection pipe 60i and drops into chamber 60a by electromagnetic valve 63.The opening portion of salt water injection pipe 60i preferably makes and makes running water be the shape that the shower shape is injected into salt 62.This water injection rate is such just enough on a small quantity of 60-70mL.This amount is according at least 1 barrel of (88L) hardness of washing water required salt amount below 40ppm is set.Reduce the internal diameter of salt water injection pipe 60i, enter the throttle nozzle (not shown) in the way of salt waterflood path, thereby dwindle path, when flow was reduced, the open hour of control salt water injecting electromagnetic valve 63 were adjusted water injection rate.Quantitatively for example behind the water injection time of 60mL (among Fig. 5 until dotted line B), microcomputer 50 is controlled salt water injecting electromagnetic valves 63 and is stopped water filling through institute.At this moment water supply electromagnetic valve 27 is also being opened, and continues to supply water.Because on lid 61, be provided with airport 61b, thus be injected into running water one side dissolving salt 62 that salt drops into chamber 60a, on one side by preventing the filter 60g of salt grain outflow, flow among the brine chamber 60k, but because check-valves 60f clogs hole 60e, so brine chamber 60k one is full, inflow just stops.
With level sensor 11 1 test know quantitative water supplied water in the outer bucket 4, microcomputer 50 is just closed water supply electromagnetic valve 27 and is stopped to supply water, and makes the just contrary rotation agitator treating of rotor 6 thing begin rinsing.In this rinsing process because do not need mechanical force, so the rotary speed of rotor can be identical with standard wash.Water supply one stops, the running water in the cylindrical vessel 60, and the pressure head that the difference in height of utilizing the running water water surface (dotted line A among Fig. 5) and salt water discharge pipe 64 to export produces passes through salt water discharge pipe 64 from salt solution outlet 29c and gently flows out.Enter upper chambers 60b because of the air from delivery port 29b simultaneously, make air pressure wherein become atmospheric pressure, so the spheroid of check-valves 60f falls under gravity, hole 60e opens.So the salt solution in the brine chamber 60e runs down into the upper chambers 60b at leisure from hole 60e, dissolving drops into this part saltwater replenishment of the salt 62 of chamber 60a and gives brine chamber 60k from salt.This lasts till that not having running water to inject salt drops into chamber 60a.At this moment, the salt of the about 20-22g of dissolving in the salt solution that flow into brine chamber 60k, concentration is 26wt%.This concentration almost saturated concentration (solubility of salt is every 100mL water 35.7g, in the time of 0 ℃) with salt is equal.Salt solution runs down into 31 layers in ion exchange resin afterwards, passes through salt water discharge pipe 64 through bottom compartment 60c from salt solution outlet 29c, is discharged in the outer bucket 4 that rinsing water is housed, and dilutes with washings.When salt solution flowed into from exchanger resin 31 in, the reaction to the left side took place on the right of Chemical formula 1, the Chemical formula 2, in the water supply running water by the time the sodium ion in calcium ion, magnesium ion and the salt solution of ion-exchange replace.Here, ion exchange resin 31 regeneration, ion-exchange capacity is brought back to life, and is utilized in the time of can supplying water in the washing procedure of washing next time.Calcium ion, magnesium ion are discharged in the washings with salt solution.
Outside salt solution flow in the mixing time (3-4 minute) of rinsing process fully the bucket 4 in.At this moment, preferably make salt solution discharge rate from salt water discharge pipe 64 be less than salt solution output from brine chamber 60k.This is used for making salt solution to be stored in upper chambers 60b.Because this way, salt solution can be only by the part of 31 layers in ion exchange resin, but the passing through of homogeneous, thus carry out high efficiency regeneration.For reaching this purpose,
(1) increase to hinder the area that prevents salt grain outflow filter 60g that salt solution passes through, make the salt solution of sufficient quantity can be by salt solution being passed through in about 1 minute in an embodiment.
(2) make the diameter of hole 60e, bigger than the internal diameter of the internal diameter of salt solution outlet 20c or salt water discharge pipe 64.In an embodiment, the internal diameter 3mm of hole 60e, the internal diameter 2mm of salt solution outlet 20c.
And, according to the position of the outlet 64a of salt water discharge pipe 64, asynchronism(-nization) under the brine stream.This is because the pressure head between the outlet 64a that flows down the salt solution water surface that depends in the cylindrical vessel 60 and salt water discharge pipe 64 of salt solution.Therefore, outlet 64a is away from bottom compartment 60c bottom, and the following time of brine stream shortens.When the internal diameter of salt solution outlet 20c is 2mm, if outlet 64a reaches 150mm apart from the bottom of bottom compartment 60c, then in the 60mL that supplies with the salt solution of dissolving 20g salt with 3-4 minute most of in cylindrical vessel 60, run down into outside barrels 4.Moreover, in fact because of surface tension residual a small amount of salt solution between ion exchange resin, but to almost not influence of washing next time.Much less, under brine stream after, append and open water supply electromagnetic valve 27, logical running water 1-2L, better to the operation of normal saline washing residual between the ion exchange resin.After final rinsing process and the end of ion exchange resin regeneration operation, after the washings discharge, carry out dehydration procedure, whole washing procedure finishes.
In the present embodiment, water upwards flow into upper chambers 60b from bottom compartment 60c during water supply, and the water that has dissolved salt during regeneration flow into the bottom compartment 60c (flow direction of water is opposite when supplying water and during regeneration) downwards from upper chambers 60b.The regeneration water is to dirty, is for the regeneration water is flowed, and the structure of deionizer 28 can be oversimplified.And, supply water and to flow upward, be because from upper chambers 60b when bottom compartment 60c flows, tap water hydraulic (0.3-8kgf/cm
2) act on the upper chambers 60b, must make check-valves 60f that the structure of anti-this pressure is arranged, the complicated and reliability that is related to structure is low in addition, and the flow direction of water is opposite during water supply and during regeneration, and also this is favourable because generally be known in the regeneration efficiency aspect.
In the ion exchange resin 31 that above-mentioned regeneration is handled, the leakage concentration when supply water next time during by running water (total hardness 100ppm) is represented with Figure 10 symbol ■.Leakage ion concentration after water flowing has just begun is identical with first (during new product), but it is fast to gather way than for the first time, surpasses 40ppm in the time of a little less than 60L, loses ion-exchange capacity when about 90L.Hardness surpasses 40ppm in washing is supplied water, but is stored in the hardness of washing water in the outer bucket 4, even also be about 38ppm as the hardness of the symbolic representation among Figure 10 at high water level (water yield 88L).Therefore, handle, when using the synthetic detergent that adds zeolite, can access the washings of hardness below 40ppm that scourability is reduced of 1 barrel of high water level by carrying out above-mentioned regeneration.In the rinsing process of following,,, but do not influence rinsing performance so supply hardness of water and former water are together because there is not ion-exchange capacity.That is, the ion-exchange capacity of washing in supplying water reached capacity because the ion exchange resin amount is set at, thus can not the above ion of sorption necessary amount, so this relates to regenerate salt amount of usefulness of the densification of realizing deionizer and minimizing.
Moreover it leaks first big of ion concentration after the 2nd time, and illustrate can not holomorphosis at above-mentioned regeneration processing intermediate ion exchange base.Obtaining first ion exchange capacity from Figure 10, is about 10g (CaCO
3Convert).For make its fully with salt solution in the sodium ion exchange, as if according to Chemical formula 1, Chemical formula 2, then need salt 12g.The about 20-22g of salt amount that supplies with in above-mentioned regeneration is handled is enough.If the water injection rate to salt is less than 60mL, the hardness when then supplying water 88L surpasses 40ppm..Therefore, the minimum 60mL that also needs of the water injection rate in salt.About 5.5g (the CaCO of ion exchange capacity after regeneration is handled 2 times
3Convert), regeneration rate is 55%.Can increase water injection rate or increase salt solution for improving this regeneration rate.But because just can handle 1 barrel (88L) when above-mentioned regeneration rate 55%, institute is so that it too much consumes salt when being higher than this regeneration rate.Therefore, the water injection rate in salt is 60mL, if consider that the words 70mL of rich amount is also enough.
According to this renovation process, calcium ion, the magnesium ion that carries out ion-exchange added in the washings with salt solution a small amount of but high concentration.So height of the hardness ratio of washings supply.But, do not have problems so hardness components influences rinsing performance.And about 6.5g is used in the regeneration of ion-exchange resin in the 20g salt that dissolves in 60mL water, discharges 13.5g in washings.But, because with a large amount of washings dilutions, so do not worry on the stainless steel that constitutes washtub 5, getting rusty.Thus, the water consumption that makes of capacity 8Kg automatic washing machine is 25-88L, dilutes then with this water that concentration is 0.054-0.015wt%, and is lower than the 0.9wt% of physiological saline.
The present invention as described above, because make the resin diameter and the amount of resin optimization of ion exchange resin, so in water supply flow 15L/ timesharing, only can realize when washing is supplied water, having quantitative ion remove the cheap deionizer of compact of function, can be loaded in the washing machine.And when rinsing is supplied water, because there is not the ion ability of removing can not the unnecessary ion of sorption, so can reduce the salt amount of regeneration usefulness.Handle for regeneration of ion-exchange resin, the salt solution that the salt dissolving of using any family all to have forms carries out in final rinsing process automatically.Therefore, that the user only needs is weekly (every washing 7 times once) puts into salt to about 150g salt and drops into such shirtsleeve operation in the chamber, need not additionally to spend the time.And salt is very cheap, almost need not cost.
Its hardness of slurry by this deionizer significantly reduces, and makes the chemical force that improves washing agent become and may scourability be improved greatly.
Further, for the serious washings of spot, improve the rotary speed of rotor with the variable-ratio control device of motor, thereby improve mechanical force, making washability improve 60% under the chemical force with above-mentioned raising acts synergistically becomes possibility.At this moment, because the raising of the chemical force that is brought by deionizer has improved the increase that suppresses wash time, and the effect of the power consumption increase when washing, so can control the cloth damage of washings, cloth is wrapped in the scope of reality, such pre-treatment such as needn't hand-wash to the flap, the spot of sleeve of the shirt that was considered as difficulty in the past, only it is come off with washing machine.
In order to improve the rotary speed (actuating speed of actuator) that clean result not only will improve rotor, when also needing to consider that use night, reduce rotary speed by control (adjustment), realize the little quiet motion (motion mode) of noise.In such motion mode (mode of washing), for preventing that cleaning effect reduces, and uses the clean effect by the soft water generation to compensate the reduction that is applied to the mechanical force on the washings.Thus, the increase of wash time (bestowing the mechanical force time) can be reduced, the high effect of cleaning can be accessed simultaneously.
In the above description, injecting running water to salt 62 is that water supply process at final rinsing process carries out, but carries out also can obtaining same effect as following.Open water supply electromagnetic valve 27, the water of final rinsing process is supplied in the outer bucket 4.With level sensor 11 1 test know the quantitative water outer bucket 4 that supplied water, microcomputer 50 is just closed water supply electromagnetic valve 27, water supply stops, and makes rotor 6 just reverse the agitator treating thing, the beginning rinsing.Water supply one stops, and the running water in the cylindrical vessel 60 just flow out by delivery port 29b and salt water discharge pipe 64, and the water level while in the reduction upper chambers 60b, the spheroid of check-valves 60f falls because of gravity, opens hole 60e.In case the water table ratio delivery port 29b in the upper chambers 60b is low, then running water all flows out from salt water discharge pipe 64.And if the water table ratio delivery port 29b low (dotted line A among Fig. 5) in the upper chambers 60b, then microcomputer 50 is opened salt solution water injection valve 63, the water of ormal weight is supplied to salt drop among the 60a of chamber.Supply to water one side dissolving salt 62 of salt input chamber 60a, by salt grain prevent filter 60g on one side, flow into brine chamber 60k, run down at leisure the upper chambers 60b from hole 60e.At this moment, because the water level in the upper chambers 60b below delivery port 29b, flows out from delivery port 29b so run down into the salt solution of upper chambers 60b, not waste, the salt solution of supply is all by in the ion exchange resin 31.Therefore, has the advantage that high efficiency is carried out the regeneration of ion exchange resin 31.
Though represent the rotor drive motor as an example with three phase induction motor obviously also can be with other forms of motor such as dc motors.At this moment, as the variable-ratio control device of motor, so long as be provided with the circuit that applies voltage that can change motor, thus the structure that changes the rotary speed control that applies voltage control motor is just passable.Obviously also can be the rotary speed that detects motor with the turn-sensitive device of Hall unit etc., feed back to convertor circuit, realize the structure of high accuracy rotary speed by microcomputer.
In addition, the present invention is not limited to the foregoing description, can carry out the technical scheme that various changes are implemented in the scope that does not break away from main points.
According to the above embodiments, because being provided with makes the raw material with ion-exchange capacity constitute compact, and under the state in being contained in washing machine, can handle the deionizer that use the back in regeneration, and the variable-ratio control device that changes the rotary speed of rotor according to the spot degree of washings, so improved the chemical force and the mechanical force that are in the suds simultaneously,, can provide the washing machine that does not increase time and electric weight and have high washability by its synergy.And the flap, the sleeve place spot that can be considered as the shirt etc. of difficulty when using existing washing machine come off.
According to the abovementioned embodiments of the present invention, because can change the actuating speed of actuator, so the time of bestowing the washings mechanical force is prolonged in vain and can obtain high clean result according to the spot degree.And because clean the ion that effect weakens by being reduced in making of containing in the washings, thereby improved the minimizing that clean result can alleviate mechanical force, so even reduce the increase that the actuating speed of actuator also can reduce wash time.
And because can make raw material regenerate at short notice and use, so ion interchange unit or deionizer can be arranged on washing machine inside with compact with ion-exchange capacity.
