As shown in Figure 3, electrode 33 is arranged to largest face with the electrolytic cell 32 of thin box shape, and for example front face 71 is parallel, forms and the tabulars of this front face 71 corresponding sizes.Such electrode 33 can be realized large tracts of land, can enough small number of electrodes 33 realize desired surface area.Electrode 33 forms at the thin-film material that substrate surface plating oxidation catalyst constitutes, and is positioned opposite to each other.Base material for example titanium is made, and thin-film material uses for example platinum.In addition, thin-film material also has gold, palladium, platinoiridita, titanium oxide etc.Each planar electrode 33 is fixed by the opposed end that the both sides of plate face direction along it constitute, and keeps the electrode spacing of regulation.The reciprocal voltage of additive polarity on pair of electrodes 33, brine electrolysis.

And it is the reciprocal pair of electrodes of polarity that electrode 33 is not limited to.For example, make the plate face of three electrodes 33 be set up in parallel also passable relative to each other.And, make the plate face of five electrodes 33 be set up in parallel also passable relative to each other.In this case, in adjacent two electrodes, 33 opposite polarity modes, the mutual conversion of polarity of being arranged to electrode 33 is also passable.Importantly have at least pair of electrodes 33 just passable, below, describe for the situation that is provided with pair of electrodes 33.

The two ends up and down of electrode 33 are fixing by electrolytic cell 32.The upper end of electrode 33 is fixed in the depressed part 77 that the inside of electrolytic cell 32 forms.This depressed part 77 is formed by the zone between the inwardly outstanding a pair of rib on electrolytic cell 32 tops 75.And the lower end of electrode 33 is fixed on the bottom surface 76 of electrolytic cell 32 by terminal cover 85.Terminal cover 85 covers the lower end of electrode 33, and the end of a thread can not accumulate in the above, and between the bottom surface 76 of sealed electrolytic cell 32 and electrode 33 lower ends.And electrode 33 also can be fixed in the left and right sides.

Electrode spacing (with reference to D2), electrode 33 interval (with reference to D3) each other of more specifically saying so is desirable in size below 5 millimeters more than 2 millimeters for example.Under the situation of 2 millimeters of interval less thaies,, cause electrolytic efficiency to descend easily, and durability also descend if the end of a thread enters electrode 33 each other easily attached to this.And, if surpass 5 millimeters at interval, must add high voltage in order to keep high electrolytic efficiency, be difficult to constitute practical structure.If, can practicably realize high-durability and high electrolytic efficiency at interval more than 2 millimeters and below 5 millimeters.

Can consider that electrolytic cell 32 and outer shell 2 usefulness different materials make.On the other hand, can consider that also electrolytic cell 32 and outer shell 2 usefulness same materials make.In this case, the processing of electrolytic cell 32 is easy when reclaiming.For example, the material of electrolytic cell 32 contains olefin resin, for example polypropylene (PP).Such resin also utilizes on outer shell 2, can improve the drug resistance for the water that contains medicaments such as washing agent and bleaching agent.And, if the material of electrolytic cell 32 contains reinforcing materials such as glass fibre, the decline of intensity in the time of can suppressing the water temperature rising ideally.

As shown in Figure 3 and Figure 4, electrolytic cell 32 have bottom surface 76, front 71, back 72, the right side 73 and the left side 74 and the end face 75 that erect around this bottom surface 76.The inside in these face 71～76 besieged cities is provided with electrode 33, holds and stays water.Electrolytic cell 32 forms than thin shape on the relative direction in front 71 and back 72.Electrode 33 is arranged to roughly parallel with front 71.Electrolytic cell 32 is made of alienable a pair of dividing body 78,79 (with reference to Fig. 2) up and down.

The top 69 of electrolytic cell 32 is along with the side that tilts uprises, and the end face of electrolytic cell 32 75 is seen to the right from the front and tilted.Water flowing road, top 34 extends out from its back, position 72 that uprises of correspondence.Water flowing road, bottom 35 extends out from the back 72 that constitutes electrolytic cell 32 lower end positions.

A pair of water flowing road 34,35 is roughly parallel to each other, and is arranged side by side along above-below direction. Water flowing road 34,35 is that circular pipe constitutes by section, forms as one with the back 72 of electrolytic cell 32.And a pair of water flowing road 34,35 be so long as can be communicated with in the electrolytic cell 32 and in the outer shell 2, and the element that can mark off the space by water is just passable, and shape is not limited to tubulose, also can consider and electrolytic cell 32 splits formation and integrally formed with outer shell 2.

Flow in the electrolytic cell 32 in outer shell 2 by water flowing road, bottom 35 water, the water route is worked to flow in water flowing road, bottom 35.And, flow out in the outer shell 2 by the water of handling in 34 electrolytic cells 32 of water flowing road, top.The water route is worked to flow out in water flowing road, top 34.Such current can be produced by the current in the outer shell 2 by for example pulsator 7 rotations.

And the water (flow) direction in a pair of water flowing road 34,35 is not special the qualification, can consider the situation opposite with above-mentioned flow direction yet.And, can have corresponding to a pair of water flowing road 34,35 that flows into and flow out, can consider that also wherein at least one square tube water route is made of a plurality of water flowings road, for example is provided with the water flowing road more than 3.And, can consider that also a pair of water flowing road is integrally formed.And, also can consider to be provided with the situation on single water flowing road.For example, can consider to be designed in single water flowing road, not distinguish and be used to a pair of water flowing road that flows into and flow out, flow into and flow out shared water flowing road.Below, illustrate that water flowing road, aforesaid bottom 35 is as flowing into water route, water flowing road, top 34 as the situation that flows out the water route.

And as shown in Figure 3, a pair of water flowing road 34,35 links to each other with outer shell 2 by sealing gasket 81.Sealing gasket 81 is for two water flowing roads the 34, the 35th, and is identical, therefore describes at water flowing road 34.

Sealing gasket 81 is made of flexible members such as tubular rubber.The inner peripheral surface of sealing gasket 81 is embedded on the outer peripheral face on water flowing road 34.The periphery of sealing gasket 81 embeds the connecting hole 67 on the lateral surface 66 (peripheral wall surfaces) that is positioned at outer shell 2 from the outside of outer shell 2.Sealing gasket 81 is guaranteed seal distance long between tubulose water flowing road 34 and the connecting hole 67.Sealing gasket 81 is installed under the state of its tube diametric(al) compression ormal weight, between the interior week in the hole 67 that is tightly connected and water flowing road 34 peripheries.Sealing gasket 81 can be along its tube diametric(al) and axial elasticity distortion.Therefore, sealing gasket 81 can absorb corresponding connecting hole 67 and water flowing road 34 scale error separately.And sealing gasket 81 can absorb a pair of water flowing road 34,35 spacing and a pair of connecting hole 67 scale error of spacing each other each other.Sealing gasket 81 absorbs in the outer shell 2 and holds the thermal deformation that produces when staying hot water, can prevent breakage and leak.And except above-mentioned tubular, sealing gasket 81 also can use O shape ring and sheet etc.

And, be formed with a plurality of for example 4 installation portions 80 near being positioned at a pair of water flowing road 34,35 on the electrolytic cell 32, be used for screw and be connected to outer shell 2.In the screw 86 of the through hole by installation portion 80 is screwed to flange 68 on the outstanding lateral surface 66 that is arranged on outer shell 2 from the outside.

As shown in Figure 4, the terminal 84 of electrode 33 is directed to the outside by the bottom surface 76 of electrolytic cell 32.Like this, even suppose that on the outer wall of water droplet attached to electrolytic cell 32, such water droplet also is not easy to take place the terminal 84 mutual short circuits of pair of electrodes 33 owing to dewfall and washing tank spilling water.Therefore, can guarantee insulation between the terminal 84.And, be provided with dividing plate 87 spaced-apart between the terminal 84 of pair of electrodes 33.Dividing plate 87 stops above-mentioned water droplet to move, and can guarantee insulating properties.Dividing plate 87 double as and electrolytic cell 32 integrally formed installation portions 80 use, and can reduce number of elements.

The assembling of unit for treating water 60 is carried out as follows.Under the state that the dividing body of electrolytic cell 32 was opened in 78,79 minutes, electrode 33 is installed in the dividing body 78.A pair of dividing body 78,79 combinations, the seal combination slit, the assembling of unit for treating water 60 has just been finished.Unit for treating water 60 with electrolytic cell 32 of case shape can utilize this monomer to carry out for example test of sealing property and electrolysis performance before being installed on the outer shell 2.Then, a pair of water flowing road 34,35 is embedded in the connecting hole 67 of outer shell 2 from the outside by sealing gasket 81.The installation portion 80 of electrolytic cell 32 is affixed on the flange 68 of outer shell 2 by screw.The terminal 84 of electrode 33 is electrically connected with power-on circuit 30.And, by opposite operation, can pull down unit for treating water 60 from outer shell 2.Upkeep operation and recovery field-strip are carried out easily.

Because such unit for treating water 60 is installed in the outside of outer shell 2, so unit for treating water 60 is installed to assembling operation on the outer shell 2, can easily carries out in the outside of outer shell 2 for the upkeep operation of unit for treating water 60, field-strip etc. when reclaiming.And, be provided with under the situation of electrode 33 between outer shell 2 and washing and dewatering cylinder 5, the space in the outer shell 2 and wherein holding stays the water must affluence, and in contrast, be installed at unit for treating water 60 under the situation in outer shell 2 outsides, can prevent that above-mentioned space and water must rich situations.

Here,, can handle as one and just can if form as the unit for treating water 60 that carries out aforesaid operations easily with outer shell 2 splits.For example, if unit for treating water 60 comprises pair of electrodes 33, is used to be installed to the installation portion 80 on the outer shell 2, monomer or with outer shell 2 actings in conjunction, it is just passable to have following function, promptly by the electrolytic scrubbing water, makes the glassware for drinking water of not sneaking into washing agent that washing (-)off properties be arranged.

And, because therefore unit for treating water 60 can further improve the operability of dismounting from outer shell 2 dismountings.Particularly, contain at electrode 33 under the situation of noble metal, reclaim ideally easily.

And, because unit for treating water 60 comprises electrolytic cell 32 and pair of electrodes 33, when assembling and safeguarding unit for treating water 60, can be used as monomer and handle, so operation is easier.

And, because electrode 33 is fixed on by dual-gripper in the electrolytic cell 32 of case shape, when operation unit for treating water 60, do not need strict attention.Therefore, can more easily assemble, safeguard, operation such as dismounting.And, even in washing and dewatering cylinder 5 is placed on outer shell 2 under when dehydration vibrative situation, can be by dual-gripper fixed electrode 33 firmly.Therefore, be not easy the situation that generating electrodes 33 comes off in electrolytic cell 32.

Owing to be provided with the sealing gasket 81 between unit for treating water 60 and outer shell 2, when being installed to unit for treating water 60 in the outer shell 2, strain by sealing gasket 81, can absorb the scale error between outer shell 2 and corresponding with it unit for treating water 60 parts, can easily assemble, and can realize sealing between unit for treating water 60 and the outer shell 2.Therefore, owing to can be also enough omit for sealing carry out bonding, can reduce built-up time, and can easily pull down and dismantle.

And, owing to be provided with a pair of water flowing road 34,35, can share the inflow and the outflow of water between electrolytic cell 32 and the outer shell 2, because water can flow between electrolytic cell 32 and outer shell 2 efficiently, can treated water do not supply with lavishly be used for effectively in the outer shell 2 washing, can improve cleaning strength, sterilization power.And, the water from outer shell 2 is flowed in electrolytic cell 32, can carry out electrolysis effectively.

Since separated from each other between a pair of water flowing road 34,35, for example, can prevent that treated water from returning electrolytic cell 32 immediately after electrolytic cell 32 is gone out.

Be provided with the different water flowing road of a pair of height and position 34,35 in the electrolytic cell 32 owing to the thin box shape on the outside 66 that is arranged on outer shell 2, can prevent ponding and accumulate air, current downflow waterborne, electrolysis efficiently (referring to the arrow among Fig. 3).

And, under the situation that water upwards flows in electrolytic cell 32, owing to be provided with water flowing road, top 34 on the top 69 of the skewed electrolytic cell that uprises 32, the water that flows upward in the electrolytic cell 32 can guide along incline direction in water flowing road, top 34, can make it rapid outflow, water is flowed.And the water flowing road, bottom 35 of electrolytic cell 32 bottoms can prevent to take place in the electrolytic cell 32 ponding.Therefore, the water in the electrolytic cell 32 can easily flow, and this is desirable.

Therefore, it is desirable that electrode 33 is arranged on the place that water flows through, electrolysis efficiently.Particularly, it can be desirable for the place of circulating in the outer shell 2 that electrode 33 is arranged on water, can improve the utilization ratio of brine electrolysis.For example, can consider to be provided with cycling mechanism, suck from outlet discharge forced circulation from inlet that electrode 33 is arranged on this cycling mechanism by making the water in the outer shell 2.Cycling mechanism can by with the bottom of outer shell 2 be connected with top can water flowing the water route that constitutes of pipe, the electrodynamic pump that water flows in this water route is formed.Formation the applicant of such cycling mechanism discloses in another No. 196894/2000 application for a patent for invention of application Japan.And, in addition, also can use the known structure that can make water circulation.

And, because electrolytic cell 32 forms the thin box shape little with respect to the outside depth size of outer shell 2, therefore can make unit for treating water 60 outstanding less from the outside of outer shell 2.For example,, can suppress that unit for treating water 60 maximizes housing 1 with housing 1 collision owing to preventing to dewater as mentioned above, can realize saving the space under situation as the thin type electrolytic cell 32 of the lateral surface 66 of the outside of outer shell 2.And, under situation, can simplify and be used to use the structure of back from the pipe of electrolytic cell 32 drainings etc. as the thin type electrolytic cell 32 of the bottom surface 64 of the outside of outer shell 2, can realize saving the space.

And because electrolytic cell 32 is arranged on the bottom of outer shell 2, for example the bottom of bottom surface 64 and lateral surface 66 can utilize and hold the low water level water that stays in the outer shell 2.For example, can shorten electrolysis time beginning to carry out electrolytic treatments midway for outer shell 2 water supply.And, can realize that electrolysis utilizes the program of low water level water.

And because electrolytic cell 32 is arranged on the lateral surface 66 of outer shell 2, and water flowing road 35 is arranged on the bottom of electrolytic cell 32, from outer shell 2 drainings the time, the water of electrolytic cell 32 inside flowed out in the outer shell 2 by water flowing road 35.

And, can consider that also a part and the outer shell 2 of electrolytic cell 32 form as one at least.In this case, be designed to electrolytic cell 32 form outstanding laterally or be desirable in the form of the inner face depression of outer shell 2 in the outside of outer shell 2.Like this, owing to can roughly keep the interior shape of outer shell 2, can prevent the space availability ratio decline in the outer shell 2 and expend unnecessary water.And, under the continuous situation of the inner face of the inner face of electrolytic cell 32 and outer shell 2, inner face is tilted mutually, water is flowed in outer shell 2 and between in the electrolytic cell 32 easily, this is desirable.

But, have the situation that is mixed with the end of a thread in the water from outer shell 2.If such the end of a thread attached on the electrode 33, worries to reduce the durability of electrode 33, electrolytic efficiency is reduced.Therefore, in mode as described below,, can not have problems even the end of a thread enters in the unit for treating water 60 yet.

Bight 82 at electrode 33 forms circular 83 (part only is shown among Fig. 4).Like this, owing to can prevent to produce corner angle on the electrode 33, so the end of a thread is difficult to hang on the bight 82 of electrode 33, and breaks away from easily.Therefore, even suppose to hang up the end of a thread, because current also can 82 disengagings from the bight automatically.

As circle 83, except the circle that when seeing, can see, also be included in the circle that when plate face direction is seen, also can see with the plate face vertical direction of electrode 33.Though circular can being formed at least on a part of bight it is desirable to be arranged on all bights that more bight particularly is in water.

Make electrode 33 interval (D3) each other be the inadhering distance of the end of a thread.This interval is being desirable more than 2 millimeters for example.Because less than 2 mm distance are stopped up by the end of a thread easily.And the interval (D4) between electrode 33 and the electrolytic cell 32 also can be above-mentioned distance, perhaps is zero, and is promptly very close to each other also passable between electrode 33 and the electrolytic cell 32.

Like this, can prevent because the end of a thread adheres to the flowability reduction that causes water.And, can prevent that the end of a thread from hindering water to contact with electrode 33.As a result, can prevent to keep high electrolytic efficiency because the end of a thread causes electrolytic efficiency decline.And, owing to allow the end of a thread to enter in the unit for treating water 60, do not need to be provided with the filter that the end of a thread is used, need be about the maintenance of the end of a thread yet.

, as shown in Figure 2,, in the washing machine bubble generator 88 can be set, be used for producing bubble from the bottom surface 64 of outer shell 2 in order to improve cleaning strength.Under the situation of this bubble generator 88 and unit for treating water 60 combinations, can carry out electrolysis with high efficiency more.

The end that bubble generator 88 has air pump 89, be connected to the air hose 90 that is used to send air of the steam vent of this air pump 89, be connected to this air hose 90 is used for air is discharged to nozzle (not shown) in the outer shell 2.Make bubble generator 88 work during washing, air sprays from nozzle, and the hole by washing and dewatering cylinder 5 enters its inside, produces bubble below pulsator 7.This bubble is broken for a plurality of trickle bubbles by the stirring of rotary pulse device 7.These trickle bubbles produce ultrasonic wave when contacting fragmentation with washings.Produce the shock wave of art of ultrasound this moment, therefore, owing to promote can improve cleaning strength with the situation comparison that does not add bubble attached to the peeling off of the dirt composition on the washings.

Bubble generator 88 also has the function of conduct from bottom 70 air fed air feeder in electrolytic cell 32 of electrolytic cell 32 except having the function that improves cleaning strength.This air feeder flows upward by the water in the electrolytic cell 32 that promotes unit for treating water 60 and produces current.Above-mentioned air hose 90 is branch halfway, and an end is to nozzle, and another end is connected to electrolytic cell 32.

As shown in Figure 4, the bottom 70 of electrolytic cell 32 is formed with the single air supply port 91 of supply from the air of air hose 90.There are a plurality of air supply ports 91 also passable.During electrolytic treatments, make air pump 89 work.The air of supplying with in the electrolytic cell 32 from air supply port 91 becomes bubble E, and come-up in electrolytic cell 32 flows in the outer shell 2 (referring to the dash-dot arrows among Fig. 4) by water flowing road, top 34.Accompany therewith, air flow makes holding in the electrolytic cell 32 stay water flow (referring to the dotted arrow among Fig. 4).Particularly, tilt on electrolytic cell 32 tops 69, water flowing road 34 is positioned under its situation of higher position, because bubble flows out from electrolytic cell 32 rapidly, so water is easier flows.Bubble does not accumulate between electrode 33.As a result, can improve electrolytic efficiency.Therefore, can to reduce in order obtaining and to stipulate the needed voltage of electrolysis ability, can make transformer 61 miniaturizations such as electronic unit such as grade, can utilize low-cost parts, and, the electric weight that is consumed can be reduced.

And air supply port 91 is arranged to the form that do not overlap from plane and electrode 33, and is arranged to not the form towards electrode 33.Like this, the mode air supply not contact with electrode 33.Therefore, can suppress because air causes electrolytic efficiency decline.And air supply port 91 bight of 76 below electrolytic cell 32 is that predetermined distance is desirable apart from electrode 33 1 ends on the horizontal direction.Make this predetermined distance be air usually not with electrode 33 contact distance, for example 10 millimeters.

And the form that is positioned on the diagonal is arranged to see from the front in air supply port 91 and water flowing road, top 34.Like this, because the distance that air flows through in electrolytic cell 32 can make the water capacity easily flow.Air supply port 91 and water flowing road, bottom 35 are arranged to see from the front and are divided right and left.Like this, the runny water of not allowing that is positioned at apart from 35 distant places, water flowing road, bottom flows easily owing to air.

Like this, the water in the electrolytic cell 32 can easily flow, and can efficiently carry out electrolysis.And, air is imported in the outer shell 2 for this reason, can help to improve cleaning strength.And, even above-mentioned air pump 89 only in electrolytic cell 32 air supply also it doesn't matter.Below, the situation of omitting bubble generator 88 is described.Returning Fig. 1 describes.

The flow chart of Fig. 8 illustrates the washing running work of standardization program.If the user has set standardization program, press start button 36, the washing running of standardization program has just begun.

At first, under the state that in washing and dewatering cylinder 5, does not have to supply water, the washings amount that washing and dewatering cylinder 5 is put in detection is load capacity (step S1), particularly, make rotation in 7 short time of pulsator, determine and inertia rotation institute's duration (from the pulse signal sum of turn-sensitive device 24) the corresponding load capacity that causes thus.Certainly, the detection of load capacity is not limited to this method, how can no matter make.

In the automatic washing machine of present embodiment, the nominal load amount in the standardization program (the once load capacity of the washings that can wash) is 8kg.Therefore, according to this nominal load amount, the size (volume) of setting washing and dewatering cylinder 5 by experimentizing in advance etc. and the performance (output) of motor 8 etc.

If S1 has detected load capacity in step,, set and the corresponding water level (step S2) of detection load capacity according to the relation table between load capacity and the water level (water yield) in the standardization program shown in Figure 9.And because the nominal load amount is 8kg, peak level is the water level corresponding with 6～8kg, promptly 591 liters.Then, show and the corresponding detergent amount (step S3) of detection load capacity at detergent amount display part 44.The user sees the demonstration of this detergent amount display part 44, and an amount of washing agent is dropped in the washing and dewatering cylinder 5.Like this, the water level settings corresponding with load capacity and the demonstration of detergent amount finish, and transfer to formal washing running.

At first, carry out washing procedure.Control part 20 is opened the first valve 13a of feed water valve 13, supplies water to and sets water level (step S4).Like this, washing agent can be dissolved in washing agent liquid in the running water and holds and stay in the outer shell 2.If supply water water level, close the first valve 13a.

Then, control part 20 produces current by making pulsator 7 with counter-rotating of fixing speed left and right sides both direction and rotation in outer shell 2, carry out the washing (step S5) of washings.Attached to the dirt on the washings, because the effect of washing agent and the effect of current (mechanical force of pulsator 7) come off.And the effect by washing agent, the dirt that prevents to come off is once more attached on the washings.Then, if crossed the wash time (for example 10 minutes) of regulation, pulsator 7 stops, and washing finishes.Controller 20 is opened draining valve 15, and washings are discharged (step S6) in outer shell 2.

Like this, if washing procedure finishes, carry out centre dehydration (step S7).Control part 20 rotates at a high speed in a direction by making washing and dewatering cylinder 5, dewaters to washings.

If middle dehydration finishes, control part 20 judges whether the washing running of this standardization program has set sterilization (step S8).Under the situation of wishing in standardization program, to sterilize to washings in the rinsing, before washing running beginning, set sterilization by the additional button 42 of sterilizing the user.At this moment, sterilization display part 50b lights, and notifies the user to carry out sterilization and sets.

At step S8, judge under the situation about setting of not sterilizing, carry out common rinsing.In standardization program, carry out rinse cycle twice.Rinse cycle carries out expelling water and rinsing (step S9) at first, for the first time.That is,, supply water Yi Bian open the first valve 13a Yi Bian control part 20 makes washing and dewatering cylinder 5 slowly rotate with the speed of for example 30rpm.Like this, make the washings on the inwall that is attached to washing and dewatering cylinder 5 generally contain water by the centre dehydration.Then, control part 20 makes washing and dewatering cylinder 5 rotate at a high speed with the speed of for example 1000rpm, dewaters to washings.Like this, contained washing agent composition and water is removed together in the washings.And expelling water and rinsing also can be to make washing and dewatering cylinder 5 rotate the situation of dewatering at a high speed when supplying water.

Like this, if rinse cycle is through with for the first time, carry out last rinse cycle.At first, control part 20 is opened the first valve 13a, supplies water to and sets water level (step S10).Between described delivery period, if hold the water that has stayed certain water level, the control part 20 controls second valve 13b on/off is added to the soft finishing agent that is placed in advance in the finishing agent containing part 12b in the washing and dewatering cylinder 5.

If supply water water level, control part 20 is closed the first valve 13a.Then, under the state that stops to supply water, pulsator about 7 counter-rotating is just changeed, the agitator treating thing carries out the not expelling water and rinsing (step S11) of washings.Like this, washings is by rinsing.If from making pulsator 7 rotation beginning rinsings begin the rinsing time (for example 2 minutes and 30 seconds) of process regulation, stop pulsator 7, expelling water and rinsing finishes.Controller 20 is opened draining valve 15, and the washings in the outer shell 2 are discharged (step S12).And, at last rinse cycle, continue to supply water that to carry out the water filling rinsing also passable even reach water level.

Like this, if last rinsing washing process finishes, (step S13) at last dewaters.It is longer than the dewatering time of middle dehydration to dewater at last, so that washings fully dewaters.Then, if last dehydration finishes, the washing running of standardization program finishes.

On the one hand,, judge under the situation of having carried out the sterilization setting, carry out the rinsing of in rinsing, sterilizing to washings at step S8.Identical with above-mentioned common rinsing, carry out rinse cycle twice.At first, carry out first rinse cycle.In this first rinse cycle, do not carry out expelling water and rinsing, carry out not expelling water and rinsing.That is, behind the water level of setting that supplies water to, agitator treating thing under the state that stops to supply water, rinsing washings (step S14, S15).Then, if from making pulsator 7 work begin to pass through the rinsing time (for example 4 minutes) of regulation, expelling water and rinsing does not finish, and carries out draining (step S16).Expelling water and rinsing and expelling water and rinsing do not compare, though the water yield of using is big, its rinsing ability has improved., finish the back relatively with expelling water and rinsing (first rinse cycle) under the common rinsing situation, the washing agent composition in the washings still less.And this, rinse cycle also can be the water filling rinsing first time.

If for the first time rinse cycle finishes, carried out for the second time in the middle of after the dehydration (step S17), transfer to last rinse cycle.In last rinse cycle, at first, begin to supply water in the washing and dewatering cylinder 5 (step S18).If the water level in the washing and dewatering cylinder 5 reaches water level, control part 20 stops to supply water, but in water supply process, if reach the predetermined water level (for example in table in Fig. 9 2nd row following water level) lower, the electrolysis rinsing (step S19) that beginning is sterilized to washings in rinsing than water level.Certainly, the pair of electrodes 33 of this predetermined water level submergence electrolysis unit 31.

This electrolysis rinsing, sterilize to washings by the hypochlorous acid of electrolysis generation and the effect of hypochlorite ion, what but the applicant experimentized etc. found that, the high brine electrolysis of hypochlorous acid and hypochlorite ion concentration is worked to washings together and make the low brine electrolysis of concentration slowly act on comparison, the sterilization effect of washings has improved.Therefore, the electrolysis rinsing is carried out as follows, promptly at first, produces the immersion process of high concentration hypochlorous acid and hypochlorite ion brine electrolysis, follows, and this high-concentration electrolytic water is diffused in the outer shell 2 together acts on washings, the rinse cycle of sterilizing.Below, describe this electrolysis rinsing work in detail according to the flow chart among Figure 10.

If beginning electrolysis rinsing at first, is carried out immersion process.That is, control part 20 makes electrolysis unit 31 work beginning electrolysis (step U1) under the state that stops pulsator 7.At this moment, sterilization display part 50b extinguishes from lighting to become, and expression is in the meaning in the electrolysis.

Comprise in the running water that trace contains the material of iron, calcium, magnesium, chlorine etc., produce active oxygen in the brine electrolysis that in electrolytic cell 32, generates by electrolysis, and produce hypochlorous acid (HClO) and hypochlorite ion (HClO ^-).If more specifically describe, constitute electrode 33 1 sides of the anode (+utmost point), water and the chlorine that wherein contains etc. carry out chemical reaction and produce hypochlorous acid and hypochlorite ion.Produce active oxygen when simultaneously, hypochlorous acid decomposes etc.At this moment, because pulsator 7 stops, stopping with electrolytic cell 32 interior water in the outer shell 2.Therefore, near 32 positions of the electrolytic cell in the electrolytic cell 32 and in the outer shell 2 produce hypochlorous acid and the high brine electrolysis of hypochlorite ion concentration gradually.

If judge from the beginning electrolysis and passed through 1 minute (step U2), the time of control part 20 decisions carrying out immersion process is soak time.Simultaneously, the time of rinse cycle is carried out in decision, promptly as stirring the mixing time of working time by pulsator 7.And decision is as making the electrolysis unit electrolysis time of 31 working times (step U3).

The conductance of running water because the content of chlorine etc. is equal along with the region difference.Therefore; in the automatic washing machine of present embodiment; control as follows, promptly from the protection point of the overcurrent of corresponding power-on circuit 30, and; stablize the point of electrolysis performance from what is called; surpass under the situation of target current value 3.5A (ampere) in the electrical current size on the electrode 33 (after, be called the electrical current value), control by energising described later; according to electrical current value intermittently power-on, make average current value become the 3.5A level.On the one hand, under the following situation of 3.5A, become continuous energising.In this case, if because the conductance of running water is low, and the electrical current value is little, the electrolysis ability is low.Therefore, be not easy to produce hypochlorous acid and hypochlorite ion, the time that reaches the normal concentration needs is long.And because the water yield in the outer shell 2 is many more, brine electrolysis is just rare more when being diffused in the outer shell 2, just needs the concentration of hypochlorous acid and hypochlorite ion high more.And the load capacity of washings is big more, makes brine electrolysis and all washings effects just need the time more.

Therefore, prepared table shown in Figure 11.Control part 20 utilizes this table, during through 1 minute, according to the electrical current value of current detection circuit 51 detections and the water level (water yield) of setting, determines soak time.That is, the electrical current value is more little, and water level is high more, and soak time is just long more.And decision is to electrolysis time that should soak time.That is, soak time is long more, and electrolysis time is long more.And, be that the load capacity of washings is determined mixing time according to water level.That is, because load capacity is many, water level is high more, and mixing time is long more.

Like this, through carrying out immersion process before the soak time of determining, near the position the electrolytic cell 32 is held and is stayed hypochlorous acid and the high brine electrolysis of hypochlorite ion concentration in electrolytic cell 32 and in the outer shell 2.

If crossed soak time, immersion process finishes, the rinse cycle of sterilizing then.That is, if judge soak time (step U4), control part 20 makes pulsator about 7 counter-rotatings and just changes.And, under the situation of having set air pump 89, make air pump 89 work air supply in electrolytic cell 32.Like this, water begins in outer shell 2 and circulation between in the electrolytic cell 32, and near in the electrolytic cell 32 and positions the outer shell 2 interior electrolytic cells 32 are held the hypochlorous acid and the high brine electrolysis of hypochlorite ion concentration that stay and are diffused into together in the outer shell 2.Then, high-concentration electrolytic water one reacts on washings, sterilizes to washings.

Electrolysis time is set at longer than soak time, and therefore, even the sterilization rinse cycle begins, electrolysis still continues.Like this, continue the water that produces electrolysis, not only hold the hypochlorous acid that stays in the immersion process, the new hypochlorous acid that produces also acts on washings.But because the power consumption of long-time powered electrode 33, it is short that electrolysis time is set at the electrolysis rinsing time that adds together than soak time and mixing time in order to suppress.Like this, the sterilization rinse cycle has just been crossed electrolysis time midway.

If judge electrolysis time (step U6), control part 20 stops the work (step U7) of electrolysis unit 31.Sterilization display part 50b lights from extinguishing to become, the meaning that the expression electrolysis finishes.Then, only proceed the rinse cycle of sterilizing by the work of pulsator 7.Owing to agitator treating thing in the brine electrolysis that has generated, washings is further sterilized around here.

If judged before mixing time finishes 2 minutes, be that the electrolysis rinsing finishes (step U8) before 2 minutes, the on/off of the control part 20 controls second valve 13b supplies water for finishing agent containing part 12b, and soft finishing agent is added in the washing and dewatering cylinder 5 (step U9).At this moment, supply water the dilution soft finishing agent by opening the first valve 13a simultaneously.By adding this soft finishing agent, further be organized submissive through the washings of sterilizing.Like this, if judge mixing time (step U10), control part 20 stops pulsator 7, and the electrolysis rinsing finishes (step U11).

Like this, if the electrolysis rinsing finishes, carry out draining (step S20), last rinse cycle finishes.Then, dewater at last (step S13), the washing running finishes.

So, control part 20 makes electrolysis unit 31 duration of works in the electrolysis rinse cycle, to the electric current that flows through pair of electrodes 33 control of switching on, below, according to the flowchart text of Figure 12 should energising control processing.

If electrolysis unit 31 is started working, at first, electrode 31 energisings (step K 1).Then, detect electrical current value (step K 2) by current detection circuit 51.If the electrical current value that detects surpasses protective current value 12A (being "Yes" in the step K 3), stop energising immediately, end energising control (step K 4).The protective current value is the threshold value of the electrical current set in order to protect the switching transistor 97 that constitutes power-on circuit 30 to flow through overcurrent.If owing to surpass the protective current value, stop energising immediately, prevent because overcurrent damage switching transistor 97.

Before spending for 4 seconds conduction time, carry out the operation of step K 2, K3 repeatedly.Then, if spent conduction time, judge directly whether the electrical current value that detects surpasses target current value 3.5A (step K 6).If below the target current value, judge that whether this electrical current value is less than lower bound current value 0.3A (step K 7), if be not less than lower bound current value, though the perhaps little number of times (for example 3 times) (being "No" in the step K 8) that does not reach regulation returns step K 1.That is, do not stop energising, energising continuously on the electrode 33.

On the one hand,, stop energising (step K 10), determine energising dwell time (step K 11) simultaneously corresponding to the electrical current value if judge above the target current value in step K 6.That is, the mean value of electrical current is the target current value in the one-period of conduction time and energising dwell time.For example, utilize calculating formula etc. to calculate.Energising dwell time=conduction time * (electrical current value-target current value)/target current value

In the present embodiment, the target current value is 3.5A, is 4 seconds owing to set conduction time, and for example, if electrical current is 7A, the energising dwell time is 4 seconds.

If determined the energising dwell time, then, judge from the polarity of counter-rotating electrode 33 (2 minutes) (step K 12) that begin whether spent the stipulated time conduction time.Stipulated time is that the energising initial stage is owing to the electrical current value that polarity inversion produces rises steadily to get off the needed time.Then, if spent 2 minutes stipulated times, upper bound current value is set at for example 9A (step K 13).

Then, judge whether the electrical current value surpasses upper bound current value 9A (step K 14).If do not surpass upper bound current value,,, return step K 1 if crossed the energising dwell time of determining (being "Yes" in the step K 16) in step K 11 though perhaps surpass the number of times (for example 3 times) (being "No" in the step K 15) that does not reach regulation.Like this, under situation about flowing through above the electrical current of target current value, electrode 33 carries out intermittently power-on, and the mean value that is controlled to electrical current is the target current value.

In step K 16, judge led to dwell time before, even on electrode 33 energising dwell time in, also carry out the detection (step K 18) of electrical current value.Then, flow through (step K 19) if this testing result has been judged electric current, the switching transistor 97 that stops with regard to energising that judging switching power-on circuit 30 breaks down, the energising control break.Taking place further to disconnect the 3rd relay 99 in the power-on circuit 30 under this unusual situation, disconnect the power supply of electrode 33.And this result is stored in the EEPROM 93, if the washing running finishes, segmentation display part 52 output abnormalities show.Then, by forbidding electrolysis unit 31 work later on, electrolysis unit 31 is not worked in the washing running afterwards.If by maintenance personal's repairing, removed unusually, eliminate the storage among the EEPROM, electrolysis unit 31 can have been worked again.Like this and since the energising control procedure in, during on electrode 33, stopping to switch in the detection electrical current, detecting under the situation of electric current, just judging switching transistor 97 and break down, ending energising control, stop simultaneously therefore can preventing to carry out undesirable electrolysis to electrode 33 power supplies.

Like this, if the end-of-job of electrolysis unit 31, if judge the electrolysis unit end-of-job in step K 9 and step K 17, energising control finishes so.

And, with the electrical current value of target current value, upper bound current value, lower bound current value comparison be shortly past the electrical current value that detected before conduction time (relatively the energising of electrical current value begins to detect after the stipulated time), be owing to flow through dash current at the energising initial stage, the current value height uses the accurate electrical current value of the current affects that is not hit.

And, for the mean value that makes electrical current becomes the target current value, fixedly conduction time, to change the energising dwell time according to the electrical current value be because following reason.Changing according to the electrical current value under the situation of conduction time,, must after the energising beginning, detect the electrical current value immediately in order to determine conduction time.In this case, owing to be subjected to the influence of above-mentioned dash current can not accurately detect the electrical current value.Therefore, can not accurately carry out intermittently power-on control according to the electrical current value.About this point, if fix conduction time, change the energising dwell time, can not be subjected to carry out current detecting in back half conduction time that dash current influences as mentioned above, therefore can accurately detect the electrical current value, can high accuracy carry out intermittently power-on control.

So, in the electrolysis rinse cycle, there is the high situation of detergent concentration in the washings.For example, have of this sort situation, promptly the washing agent that uses in the washing process is many, the fully rinsing of this washing agent, and under the residual more state, the electrolysis rinsing is carried out in last rinsing in the washings.Carry out under the situation of electrolysis under the state that detergent concentration is high like this, because the influence of composition in the washing agent, different with common water (running water), existence can not be carried out the problem of desirable electrolysis.And, since this washing agent composition in most cases conductance become very good, in this case, flow through overcurrent, if work in this case, the power-on circuit 30 that has an electrolysis unit 31 is with the problem of damaging.Therefore, be set with in the automatic washing machine of present embodiment and be used to the upper bound current value of judging that detergent concentration is high, described detergent concentration is used to judge overcurrent.

For example, because the conductance that detergent concentration uprises washings in the washings becomes very good, the electrical current value surpasses 8A, judges above upper bound current value in the step K 12 of above-mentioned energising control, and judges in step K 13 and to reach stipulated number.If like this, judge whether the polarity of electrode 33 reverses (making the energising direction counter-rotating of electric current) (step K 21), if polarity is not reversed just polarity inversion (step K 22), return step K 1, begin energising control once more.On the one hand,, do not change, just end energising control even i.e. polarity inversion surpasses the situation of upper bound current value if polarity has been reversed.

In the automatic washing machine of present embodiment, if except detecting polarity as mentioned above, as described later whenever having crossed the regulation reversing time with regard to reversed polarity above the electrical current value of upper bound current value counter-rotating electrode 33.The result of the experiment that the applicant carries out etc. shows, if give electrode 33 energisings after the polarity inversion, though the time is according to various conditions and difference, from beginning to be energized in the time of several seconds to a few minutes (about 2 minutes), the electrical current value when after this stablizing larger about 1A (ampere) level.Therefore, there are the following problems, even flow through when stablizing under the situation of the electrical current that does not surpass upper bound current value, owing to surpass upper bound current value in the conduction time at initial stage after polarity inversion, undesirable termination can take place in the energising of electrode 33 control.

To this, in the present embodiment, step K 12 in above-mentioned energising control, if judge from the polarity of counter-rotating electrode 33 and begin also do not have 2 minutes conduction time, cause that according to the polarity inversion reason electrical current value rises, upper bound current value is set at the high numerical value of current value 9A when stable, for example 10A (step K 23).Therefore, can not wish the energising control interruption of electrode 33 owing to the reason of polarity inversion.

And, because the thin-film material that is plated on the electrode 33 all is consumed when electrolysis unit 31 work, in use all the year round, can full consumption finish eventually.And, not carrying out under the thin-film material state under the situation of electrolysis having like this, base material is dissolved out, and exists to adhere to the problem of polluting washings on the clothing that is in the suds.Run out of at thin-film material, only under the situation of remaining base material, even add and just often identical voltage, electrode 33 does not extremely have electric current to flow through.Therefore, in the automatic washing machine of present embodiment, further set lower bound current value, be used to judge whether the thin-film material that is plated on the electrode 33 has not had.

For example,, be very difficult to flow through electric current on the electrode 33,, judge less than lower bound current value, and judge in step K 8 and to reach stipulated number in step K 7 if the electrical current value becomes less than 0.3A because the thin-film material of electrode 33 becomes and do not had fully.If like this, stop to electrode 33 energisings (step K 20), the same with above-mentioned situation above upper bound current value, if reversed, just end energising and control in the polarity of step K 21 judgement electrodes.If the termination electrolysis, sterilization display part 50b lights the meaning that expression is ended from extinguishing to become.

And the energising control of electrode 33 is ended in the electrolysis rinsing midway, even the work of electrolysis unit 31 is ended, itself proceeds rinsing.Like this, at least, can guarantee rinsing performance.But, because immersion process does not have help to rinsing performance, under the situation that the work of electrolysis unit 31 is ended, end immersion process, it is also passable to transfer to sterilization rinse cycle (becoming just rinsing this moment).And under the situation of energising control break, it is also passable that replacement water carries out the electrolysis rinsing once more.

Then, the automatic washing machine of present embodiment has the washing procedure of detergent-free, and this is second characteristic.Below, according to the flow chart of Figure 13～Figure 15 (a) and Figure 15 (b), the washing running work of detergent-free program is described.

This detergent-free program is that to be fit to washing mainly be the program of the dirty low weight clothing of sebum dirt and sweat dirt, washs with brine electrolysis and does not use the program of washing agent by electrolysis.Owing to do not use washing agent, the washing of children's clothing of the most suitable skin sensitivity.And in other words the detergent-free program is exactly the electrolytic scrubbing program, in the present embodiment, owing to do not use washing agent, is called the detergent-free program.

If the user sets the detergent-free program, press start button 36, since the control of control part 20, the washing running of beginning detergent-free program.Owing to set the detergent-free program, electrolysis display part 50a and sterilization display part 50b light simultaneously, notify the user to set the detergent-free program.

At first, carry out the load capacity sensed water level and set processing (step F 1).This load capacity sensed water level is set and is handled operation as shown in figure 14.That is, at first, under the state that in washing and dewatering cylinder 5, does not have to supply water, detect the washings load capacity (step F 101) of putting into washing and dewatering cylinder 5.In the automatic washing machine of present embodiment, the nominal load amount in the detergent-free program is 4.5kg.And, according to this nominal load amount, the performance (output) etc. of setting electrolysis unit 31 by experimentizing in advance etc.And, if electrolysis unit 31 is just sterilized to washings as above-mentioned standardization program, have the performance that can fully sterilize to the washings of the nominal load amount 8kg of standardization program.

If detected load capacity, judge whether the load capacity that detects surpasses nominal load amount 4.5kg (step F 102) in step F 101.If surpass the nominal load amount, as shown in Figure 9,, set and the corresponding water level (step F 103) of detection load capacity according to the relation table between load capacity and the water level (water yield) in the detergent-free program.And because the nominal load amount is 4.5kg, peak level is the water level corresponding with 3～4.5kg, is 431 liters.And, owing to do not use washing agent in this detergent-free program, do not carry out the demonstration of detergent amount.

On the one hand, in step F 102, if judge above the nominal load amount, output is used to notify the adding excessive signal (step F 104) that adds excessive washings.That is, buzzer 29 discontinuous operations are sent the buzzer of " Pi, Pi, Pi, Pi ", simultaneously in block display part 52 output expressions " U8 " such user's mistake (mistake that user's maloperation causes) for example.Though buzzer has stopped, judging by before the start button 36, continue to show user's mistake.And, by changing the buzzer switch time etc., buzzer that adds excessive signal and the abnormal sound difference of notifying other abnormal failure and user's mistake are come.

If the user has realized the adding excessive signal, press start button 36, judge this situation in step F 105, the output that adds excessive signal is that the demonstration of user's mistake stops, and interrupts washing running (step F 106) simultaneously.Then, add excessive washings, press start button 36 once more, judge, just begin the washing running once more in step F 107 if the user takes out.

So, if set water level, the load capacity sensed water level is set processing and is finished, and then, carries out the prewashing process.At first, open the first valve 13a, beginning is water supply (step F 2) in washing and dewatering cylinder 5.If the water level in the washing and dewatering cylinder 5 has reached water level, close the first valve 13a, stop to supply water.But in water supply process, if reach the predetermined water level (for example following water level of the row of second in the table of Fig. 9) lower, beginning electrolysis prewashing (step F 3) than water level.Certainly, in this predetermined water level, the electrode 33 of electrolysis unit 31 does not have in the entry.

At first, by pulsator about 7 counter-rotating rotations, in outer shell 2, produce current.Simultaneously, electrolysis unit 31 work.And, under the situation of having set air pump 89, make air pump 89 work air supply in electrolytic cell 32.At this moment, electrolysis display part 50a extinguishes from lighting to become under the situation that sterilization display part 50b lights, and expression is in the electrolysis.

As mentioned above,, in brine electrolysis, produce hypochlorous acid and hypochlorite ion certainly, near electrode 33, produce active oxygen by carrying out electrolysis.And this brine electrolysis has alkalescent character.By the stirring work and air pump 89 air supplies of pulsator 7, water flows in electrolytic cell 32 and between in the outer shell 2 back and forth, is full of brine electrolysis in the outer shell 2 gradually.Attached to the dirt on the washings since the effect of alkaline water and the effect of current (mechanical force of pulsator 7) come off.And be decomposed under the effect of the dirt active oxygen in electrolytic cell 32 that comes off from washings, prevent that dirt is once more attached on the washings.And, since hypochlorous acid and hypochlorite ion most of with dirt in various bacterial actions, can not too expect here sterilization effect to washings.

Then, if begun to surpass the prewashing time (for example 3 minutes) of stipulating from electrolysis prewashing, stop the work of electrolysis unit 31, stop pulsator 7 simultaneously, carry out from outer shell 2 internal drainages, prewash procedure finishes (step F 4).Like this, by this prewash procedure, remove the dirt on the washings generally.

In this electrolysis prewash procedure, the same with the electrolysis rinsing program, also carry out the energising control of electrode 33.Therefore, in the detergent-free program, because the input washing agent of user's mistake,, under the situation that electrical current becomes very high, in electrolysis prewashing process, end the work of electrolysis unit 31 owing to reasons such as the detergent concentration of pre-wash water uprise., pulsator 7 works on, and itself proceeds prewashing.At this moment, if because washing agent, by the auxiliary inoperative part dirt of brine electrolysis that comes off of the effect of washing agent.Simultaneously, even under the situation of reason that is not washing agent,, also can realize the effect of prewashing though the dirt effect that comes off a little degenerates.

And, remove the such prewashing purpose consideration of dirt of washings before generally from carrying out real washing, in this prewash procedure, the life-span of consideration electrolysis unit 31 and the electric power that is consumed etc., the structure that electrolysis was not worked, do not carried out to electrolysis unit 31 is also passable.

If the prewashing process finishes, carry out centre dehydration (step F 5).The work of this centre dehydration is shown in Figure 15 (a) and Figure 15 (b).That is, start washing and dewatering cylinder 5, make it to rotate (step F 501) at a high speed in a direction.Like this, the washings in the washing and dewatering cylinder 5 is dehydrated.Then, if crossed the dewatering time of regulation, stop washing and dewatering cylinder 5, middle dehydration finishes (step F 502, F503).

So, in the dehydration course of work, the imbalance by washings in the uneven sense switch 58 detection washing and dewatering cylinders 5 promptly, detects the outer shell 2 that causes owing to this imbalance reason and shakes unusually.Then,, judge washings in step F 504 and be in non-equilibrium state, stop washing and dewatering cylinder 5, interrupt dehydration (step F 505) if detect shaking unusually of outer shell 2 by uneven sense switch 58.Then, remove the imbalance of washings in the washing and dewatering cylinder 5, carry out uneven correction work (making work in order) (step F 506).

In imbalance correction work, at first, open the first valve 13a, water supply start (step F 561).Then, whether the water level of judge setting is the peak level (step F 562) in this detergent-free program.Under the situation that is not peak level, set water level if supply water to, close the first valve 13a, stop to supply water (step F 563, F565).

On the one hand, the water level of judging setting in step F 562 is under the situation of peak level, set than peak level also high make water level in order.Then, supply water and make water level in order, close the first valve 13a (step F 564, F565) to this.This make in order water level in the standardization program for example than the water level of 511 (liters) of high two row of peak level of detergent-free program.Like this, be under the situation of peak level at the water level of setting, make that to make the water table ratio peak level in order also high, be because following reason.That is, there is such situation, under the situation that adds the washings more more a little, because all factors detect mistakenly in the nominal load amount in the load capacity testing process than nominal load amount.In this case, though water level is the water level of corresponding nominal load amount, promptly be the peak level in the detergent-free program, the water shortage of corresponding load capacity under this state, washings becomes bulk easily, and washings imbalance in the washing tank takes place easily.Therefore, detect under the unbalanced situation setting under the situation of peak level, be contemplated to as mentioned above situation just over the nominal load amount.In this case, exist the peak level water yield for actual loading water gaging quantity not sufficient, the problem that can not fully make in order.

Then, finish, start pulsator 7, just changeing agitator treating thing (step F 566) by counter-rotating if supply water.Washings is made in order like this, removes the imbalance of washings in the washing and dewatering cylinder 5.Like this, if spent the time of making in order of regulation, stop pulsator 7, after the draining, uneven revision program finishes (step F 567～F569).If removed imbalance, begin dehydration work once more.

Like this, owing to be set under the situation of peak level at water level, if the imbalance of detecting, supply water than peak level also high make water level in order, at this water level agitator treating thing, even also can make in order really under a little more than the state of nominal load amount at washings.

So, if middle dehydration finishes, carry out electrolytic scrubbing program (step F 6～F8).Work in the electrolytic scrubbing program is identical with the work in the above-mentioned electrolysis prewash procedure, is longer than the prewashing time but make the electrolytic scrubbing time set of electrolysis unit 31 and pulsator 7 work.For example, corresponding with 3 minutes prewashing time, the electrolytic scrubbing time set is 10 minutes.Like this, by this electrolytic scrubbing program, fully remove the dirt of washings.And electrolysis display part 50a extinguishes in electrolytic scrubbing.

In this electrolytic scrubbing process, also carry out the energising control of electrode 33.Therefore, as mentioned above, because the user drops into washing agent mistakenly, under the many situations of residual washing agent composition on the washings, carry out electrolytic scrubbing, owing to the electrolysis concentration of washings such as uprises at reason, the electrical current value becomes under the very large situation, ends the work of electrolysis unit 31 midway at electrolytic scrubbing.At this moment, pulsator 7 works on, and itself proceeds washing.Electrolysis display part 50a is become by flicker and lights, and is different with the situation of prewashing process in this electrolytic scrubbing process, the dirt of the washings that must fully come off.Therefore, if drop into the reason of washing agent, do not know whether can guarantee washing (-)off properties by the effect of washing agent, under the insufficient situation of this detergent amount and be not to drop under the situation of reason of washing agent (being as hereinafter described) owing to the reason that drops into the good material of other conductance such as shower cream, exist electrolysis unit 31 to stop, can not guaranteeing cleaning fully the problem of ability, therefore, become big at electrical current, under the situation of the work of electrolytic scrubbing process Halfway Stopping electrolysis unit 31, carry out the electrolytic scrubbing program of appending described later.

If the electrolytic scrubbing EP (end of program) is carried out the middle dehydration second time (step F 9).This work of dewatering for the second time is identical with initial middle dehydration work.

If dehydration finishes for the second time, judge whether to be ended (step F 10) in the work of electrolysis unit 31 midway of electrolytic scrubbing process because the electrical current value surpasses upper bound current value.If do not end, transfer to the electrolysis rinse cycle.On the one hand, judge in the electrolytic scrubbing process and midway under the suspended situation of work of electrolysis unit 31, append electrolytic scrubbing process (step F 11～F13).This work of appending the electrolytic scrubbing program is identical with the electrolytic scrubbing program with prewash procedure, but makes the wash time of appending of electrolysis unit 31 and pulsator 7 work be set at longlyer than the prewashing time, lacks than the electrolytic scrubbing time.In the present embodiment, for example, append wash time and be set at 5 minutes.Like this,, do not need many like that time of electrolytic scrubbing time,, must wash more fully than prewash procedure because how many electrolytic scrubbing processes has carried out some washings.

Appending under the electrolytic scrubbing program situation, carrying out again in the middle of three times carrying out electrolysis rinsing program (step F 15～F17) after the dehydration (step F 14).

The work of setting the situation of carrying out the electrolysis rinsing in sterilization, the final rinsing program in the work of this electrolysis rinsing program and the standardization program is identical.In the electrolysis rinsing, electrolysis display part 50a lights, and sterilization display part 50b extinguishes.Soak time, mixing time, electrolysis time are still lacked owing to comparing nominal load amount (peak level) with standardization program as shown in figure 11, and soak time and electrolysis time are just according to the electrical current value, and mixing time is certain.And mixing time is with longer corresponding to the mixing time of identical water level in the standardization program and electrical current value.

Like this, if the electrolysis rinsing program finishes, carry out dewatering time than the longer last dehydration (step F 18) of middle dehydration.Should last dehydration work of dewatering be that dewatering time is long, identical with middle dehydration work.Then, if last dehydration finishes, the clean running of detergent-free program finishes.

And, carry out the time (working time of electrolysis unit 31) of electrolysis prewashing and carry out time of electrolytic scrubbing also passable according to the size variation of electrical current.In this case, the electrical current value is more little, and the time of carrying out is just long more.And, carry out the time (working time of electrolysis unit 31) of electrolysis prewashing and carry out the time of electrolytic scrubbing changing also passable according to the load capacity of washings, the water yield (water level).In this case, the load capacity and the water yield are many more, and the time of carrying out is just long more.If like this, can guarantee cleaning strength.

So, flow through overcurrent between the pair of electrodes 33 when electrolytic scrubbing or during the electrolysis rinsing, judge electrical current value on the electrode 33 greater than the reason of protective current value 12A in the step K 3 of above-mentioned energising control, consideration is following reason.It is many to contain the high material of conductances such as washing agent or shower cream, promptly owing to the concentration height of these materials, flows through the situation of overcurrent under the situation that the conductance of water becomes very high.And, in electrolytic cell 32, adding the high foreign matter (for example hair clip, safety plug, clasp etc.) of conductance, these foreign matters are clipped in the situation that flows through overcurrent between the electrode.Under the situation owing to previous reason, if replace water in the outer shell 2 in the program of carrying out the back or when running washing, the possibility of elimination overcurrent is very big.On the one hand, under the situation owing to back one reason, owing to do not get place's foreign matter, the possibility that can not eliminate overcurrent is just big.Therefore, in the automatic washing machine of present embodiment, infer these reasons, and take measures according to reason.Promptly, under the situation about setting of in standardization program etc., sterilizing, after last rinsing program draining, and after the electrolysis rinsing program draining of detergent-free program, carry out the unusual judgment processing of electrode as follows, simultaneously after the dehydration in the end, according to the result of the unusual judgment processing of the described electrode end process that turns round.

The flow chart of Figure 17 illustrates the operation in the electrode abnormality processing.At first, in the time of electrolytic scrubbing or electrolysis rinsing etc., the judged result in the above-mentioned energising control step K 3 is if judge electrical current value on the electrode 33 greater than protective current value 12A, judges whether to end electrolysis (G1).Under the situation of not ending electrolysis, this judgment processing finishes, but ending under the situation of electrolysis, only (for example 0.5 second) energising in the short time of regulation on the pair of electrodes 33 detects electrical current value on the electrode 33 therebetween (step G2～G4) by current detection circuit 51.At this moment, owing to almost all discharge by the water in the draining outer shell 2, the water in the electrolytic cell 32 is also almost all discharged, and pair of electrodes 33 cannot not be under waterly or state under water hardly.

Then, judge that whether the current value of detection is greater than protective current value 12A (step G5).At this moment, if the conductance height of water is the middle reasons that produce overcurrent such as electrolytic scrubbing, if reduce the water between the electrode or do not have water, because conductance descends, the decline of electrical current value becomes below the protective current value.On the one hand, if the reason of foreign matter, even reduce the water between the electrode or do not have water, because the conductance size is constant, the electrical current value is still greater than the protective current value.

If the electrical current value is greater than the protective current value in judging in step G5, whether the number of times of just judging greater than the protective current value reaches stipulated number (for example 3 times) (step G6).Do not reach stipulated number, just return step G2, the electrical current of detecting electrode 33 once more, if but reach stipulated number, just judging and producing overcurrent in electrolytic scrubbing or the electrolysis rinsing is owing to the possibility that accompanies foreign matter between the electrode is big, exists expression electrode 33 unusual information to be stored in the EEPROM 93 (step G7).Then, this judgment processing finishes.

On the one hand, if judge the electrical current value less than the protective current value at step G5, just judging and producing overcurrent in electrolytic scrubbing or the electrolysis rinsing is because the conductance of water is very high, does not need to carry out abnormality processing, and this judgment processing finishes.

And in the detergent-free program, it is also passable to carry out the unusual judgment processing of described electrode after the prewash procedure draining or after the draining of electrolytic scrubbing program.

The flow chart of Figure 18 illustrates the operation of running end process.At first, must notice washing running finish buzzer 29 pipe (step P1).Then, whether judge among the EEPROM 93 the unusual information (step P2) of storage electrode.If stored such information, after the standby in 5 seconds, make the work of automatic power disconnecting circuit (not shown), the switch 49 of cutting off the electricity supply automatically cuts off the power supply input (step P3, P4) of machine itself.

On the one hand, if there is the unusual information segmenting display part of storage electrode 52 just to sandwich electrodes such as foreign matter 33 between output expression electrode among the EEPROM 93 abnormal show (step P5) of the meaning does not unusually take place.For example, show [EC] on the segmentation display part 52.Like this, if spent 20 minutes, the work of automatic power disconnecting circuit, the switch 49 of cutting off the electricity supply automatically cuts off the power supply input (step P6, P4) of machine itself.

By the abnormality alarm of such 20 minutes clock times, after hearing the buzzer taking-up washings that running finishes, the user notices that electrode is unusual.Then, take out place under repair such as foreign matter by the machinist after, finished the unusual work of eliminating, the electrode abnormal information among the EEPROM 93 disappears, and has removed abnormality.

, place under repair is not limited to remove unusual work, even the power supply of machine itself is cut off, EEPROM 93 relayings renew accumulate utmost point abnormal information.Therefore, connect washing when running that power supply carries out any program in the back, after running finishes, carry out abnormal alarm by above-mentioned running end process.And, set the user under the situation of detergent-free program, judged whether to store the unusual information of electrode, if stored the electrode abnormal information, electrolysis display part 50a that generally lights and sterilization display part 50b become and extinguish.Like this, the unusual intention notice user of electrode.And, even in standardization program etc., set under the situation of sterilization, judged whether to store the unusual information of electrode by additional sterilization button 42 the user, if stored the electrode abnormal information, the sterilization display part 50b that generally lights becomes and extinguishes.And, under the situation of having stored the unusual information of electrode, not to electrode 33 control of switching on, do not make electrolysis unit 31 work in electrolytic scrubbing or the electrolysis rinsing program.

And in the detergent-free program, under the situation of having stored the unusual information of electrode, because electrolysis unit 31 is not worked, washing (-)off properties and sterilization effect descend greatly, in the detergent-free program, preferably wash running itself and also do not carry out.Under the situation of having carried out the sterilization setting, the running of carrying out common (setting sterilization) is also passable.And the abnormal alarm of the abnormal alarm when carrying out detergent-free program or sterilization and set when turning round end process is identical,, also can be shown as [EC] at segmentation display part 52 that is.

Like this; in the automatic washing machine of present embodiment, in electrolytic scrubbing or electrolysis rinsing, detect under the situation above the electrical current value of protective current value, owing to end electrolysis; not having big load to be applied on the power-on circuit 30 on the electrode 33, can realize protecting power-on circuit 30.And, infer the reason that produces such overcurrent by carrying out the unusual judgment processing of electrode, reason in overcurrent is because the conductance of water, under the high situation of the possibility of replacement water elimination, do not carry out abnormality processing, in the electrolytic scrubbing of back or electrolysis rinsing, can carry out electrolysis, therefore not reduce the operating efficiency of machine.On the one hand, owing to reasons such as the high foreign matter of conductance are clipped between the electrode, under the low situation of the possibility eliminated of remaining in operation in this state, owing to carry out the unusual abnormality alarm of electrode, unusual by making machinist's grade to handle such electrode as early as possible.And, owing to carry out abnormality alarm after in the end dehydration finishes, notice the abort running the user, it is insufficient can not dewater, and can dewater really.

And under the unusual situation of such electrode, even cut off the electricity supply, the electrode abnormal information does not disappear yet, and is stored in the EEPROM 93, when setting detergent-free program etc. afterwards and carrying out the washing procedure of electrolysis, carries out abnormal alarm once more.Therefore, even the user does not notice abnormal alarm at first, also can in the running of the washing procedure that carries out electrolysis, notice.And, because the unusual information of storage electrode among the EEPROM 93 is carried out abnormal alarm at last in the washing running, the user is further noticed have abnormality.And, under such electrode abnormal conditions,,, can further realize protecting power-on circuit 30 because electrolysis unit 31 is not worked even in the washing running of back, set the washing procedure that carries out electrolysis.

But in aforesaid power-on circuit 30, owing to any reason transformer damages, between transformer one end and the other end under the on-insulated situation, existence will not have the voltage of step-down to be added to problem on the electrode 33.And if the user touches in the water jacket 2 hold under the situation of staying water under such state, the electric current that human body can be felt flows through human body, has scaring user's problem.Therefore,, in the automatic washing machine of present embodiment, carry out control as described below, this control work is described according to flow process Figure 19 by 20 pairs of power-on circuits of control part 30 for such thing does not take place.

At first, if make power switch 49 work (49a of contact portion closure), connect power supply, the 3rd relay 99 closures (step R1, R2).At this moment, the contact of the first relay 98a is connected to terminal b, and the contact of the second relay 98b is connected to terminal d.Like this, the first electrode 33a and the second electrode 33b the two be connected to ground connection one side (DC 0V side) of dc voltage circuit 96 by the 3rd relay 99, switching transistor 97.

Then, judge whether loam cake 19 opens (step R3).Whether open if detect loam cake 19, open, disconnect the 3rd relay (step R4) if in step R3, detect loam cake 19 by switch sense switch 57.Power supply one side (DC 40V side) and ground connection one side of the first electrode 33a and the second electrode 33b the two and dc voltage circuit 96 are in state of insulation.Then, judge whether loam cake 19 closes (step R5), if loam cake 19 is closed, returns step R2, connects the 3rd relay 99 once more.

On the one hand, do not open, just judge electrolysis unit 31 whether work (step R6) if judge loam cake 19 at step R3.If carry out electrolytic scrubbing or electrolysis rinsing, make electrolysis unit 31 work, the polarity of the corresponding first electrode 33a and the second electrode 33b drives the first relay 98a or the second relay 98b (step R7～R9).Promptly, the first electrode 33a is an anode, and the second electrode 33b is a negative electrode, and electric current flows to from the first electrode 33a under the situation of the second electrode 33b (becoming first polarity later on), because the first electrode 33a links to each other with power supply one side of dc voltage circuit 96, the contact of the first relay 98a links to each other with terminal a.On the one hand, the second electrode 33b is an anode, the first electrode 33a is a negative electrode, electric current flows to from the second electrode 33b under the situation of the first electrode 33a (becoming second polarity later on), because the second electrode 33b links to each other with power supply one side of dc voltage circuit 96, the contact of the second relay 98b links to each other with terminal c.Therefore, according to the energising control of above-mentioned electrode 33, the connection of gauge tap transistor 97 disconnects (control R10).

Carry out duration of work (control period of switching on) at electrolysis unit 31, judge whether loam cake 19 opens (step R11),, just judge whether to stop electrolysis unit 31 (step R12) if loam cake 19 is opened.If stop electrolysis unit 31, with regard to cut-off switch transistor 97 (step R13).Then, under the first polarity situation, the contact of the first relay 98a links to each other with terminal b.Under the second polarity situation, the contact of the second relay 98b (the step R14～R16) that links to each other with terminal d.Then, return step R3.Like this, if washing such as detergent-free program running finishes the switch 49 (step R24) of manually or automatically cutting off the electricity supply, end-of-job.At this moment, the 3rd relay 99 disconnects.

On the one hand, cover 19 and close, connect switching transistor 97 (step R17) if judge at step R11.Then, under the first polarity situation, the contact of the first relay 98a links to each other with terminal b, under the second polarity situation, and the contact of the second relay 98b (the step R18～R20) that links to each other with terminal d.Then, disconnect the 3rd relay 99 (step R21).Like this, power supply one side (DC 40V side) and ground connection one side of the two and dc voltage circuit 96 of the first electrode 33a and the second electrode 33b are in state of insulation.Then, judge whether loam cake 19 closes (step R22),, connect the 3rd relay 99 (step R23) once more if loam cake 19 is closed.Then, return step R7, electrolysis unit 31 is started working once more.

Like this, in the automatic washing machine of present embodiment, connect at machine itself under the situation of power supply, when loam cake 19 is opened, be that the user touches under the situation of the water in the washing and dewatering groove 5, owing to necessarily be in state of insulation between the first electrode 33a and the second electrode 33b the two and the dc voltage circuit 96, even owing to any reason contingency transformer 95 damages, do not apply high voltage on any one electrode, under such state, even the user touches the water in the washing and dewatering groove 5, do not have electric current yet and flow through.

And, do not constitute and connect power supply the 3rd just connection of relay 99, constitute and push beginning switch 36 and begin washing running the 3rd relay 99 and just connect also passable, and, when in fact electrode 33 being switched on control, that is, the first relay 98a or the second relay 98b are the same with switching transistor 97, connect by timer and also can.Like this, keep the state of insulation of electrode 33 for a long time owing to can try one's best, even, also can try one's best the situation that the user contacts the current overcurrent in the washing and dewatering groove 5 not take place because the fault of switch sense switch 57 etc. can not detect under the situation of switch of loam cake 19.

And, in the present embodiment, insulating properties are low when disconnecting owing to employed switching transistor 97 (semiconductor switch), use the 3rd high relay 99 of insulating properties, but under the situation of using the high switching transistor of insulating properties, do not use the such relay of the 3rd relay passable yet.In this case, described switching transistor plays switching device of the present invention and second switch device simultaneously.

More than, an embodiment of washing machine of the present invention and scrubber is illustrated, but the present invention is as follows, is not limited to the foregoing description.

Washing machine of the present invention is not limited to automatic washing machine.By outer shell be arranged on horizontal shaft type cylinder in the outer shell to constitute the so-called tumbling-box washing machine of washing tank also passable.And it is that so-called two-tub washing machine is also passable that washing tank designs respectively with the dehydration cylinder as a cylinder.
