Abstract
The present invention provided a washing machine which excellently performs washing and killing harmful bacteria through utilizing electrolysis. When energizing control is started in an electrode 33, an energizing time to the electrode 33 is read from an EEPROM 93 (step G1) at the point of time when last-time energizing control is ended. The counting of the energizing time is started after the read energizing time (step G2). When a time becomes an inversion time in a step G3, energizing control for the electrode 33 is stopped (step G4), and then, a changeover switch 98 is operated to invert the polarity of the electrode 33 (step G5). When the polarity inversion is ended, the energizing time is reset, counting is restarted and energizing control is started again (steps G6-G8). A scale is prevented from adhering onto the front surface of the electrode so that stable cleaning performance and harmful bacteria killing performance are secured.

, when realizing such washing machine, following problem appears.
If under the identical polar state, give electrifying electrodes continuously, adhere to scale on the electrode surface, there is the problem that is not easy to flow through electric current, electrolysis ability drop between the electrode.Therefore, existence can not obtain the problem of sufficient washing (-)off properties and sterilization ability.
And, if after the polarity inversion of electrode, begin energising, though current value in the time of therefore etc. and different, but from beginning to be energized in the time till several seconds to a few minutes (about 2 minutes), flow through the big some electric currents of the stabling current that promptly flow through originally than after this electric current, the result of experiment etc. has proved this point.In order to protect circuit to electrifying electrodes; can consider such structure, upper bound current value (if switch on for a long time continuously, the current threshold that electrical current damages) promptly is set; if flow through electric current greater than this upper bound current value; just stop energising, end electrolysis, but in this case; there are the following problems; though promptly stabling current is judged above upper bound current value in the galvanization after firm reversed polarity less than upper bound current value, will end electrolysis.
And the running water conductance is different because the content of the different chlorine in region etc. is not equal.Therefore, the size of current that flows through electrode disperses, and the electrolysis performance disperses, and the result exists can not obtain the stable washing (-)off properties and the problem of sterilization ability.
And, owing to which kind of reason make under the situation of power-on circuit damage, there is the problem that on electrode, continues energising.In this case, there is the problem of carrying out undesirable electrolysis.
Purpose of the present invention is exactly by solving such problem, a kind of washing machine (scrubber) that can utilize electrolysis to wash (cleaning) and sterilization well being provided.

This electrolysis unit 31 has the electrolytic cell 32 that is provided with respectively with outer shell 2, be arranged on pair of electrodes 33 in this electrolytic cell 32, be connected electrolytic cell 32 tops 69 and outer shell 2 water flowing road, top 34, be connected the water flowing road, bottom 35 of electrolytic cell 32 bottoms and outer shell 2.
Electrolysis unit 31 is installed on the following height and position, and promptly when holding the water level that stays water in the outer shell 2 and reach water level, at least a portion of pair of electrodes 33 there is not in the entry.
Pair of electrodes 33 is made of the first electrode 33a and the second electrode 33b, and the first electrode 33a and the second electrode 33b are the square plate shapes.Electrolytic cell 32 forms the thin box shape less with respect to the peripheral wall surfaces depth dimensions (with reference to D1) of outer shell 2.And the first electrode 33a and second electrode 33b electrode surface separately are arranged in the electrolytic cell 32 with decided spacing parallel arranging facing on the direction of outer shell perisporium.By such formation, owing to can suppress electrolysis unit 31 from outer shell 2 overhang laterally, electrolysis unit 31 collision housings 1 in the time of therefore can preventing in dehydration outer shell 2 vibrations.Therefore, can prevent that housing 1 from becoming big.
, can consider that also the electrolytic cell 32 of electrolysis unit 31 is integrally formed on the outer shell 2, electrode 33 is installed in the inside of outer shell 2.In this case, in narrow outer shell 2 inside, installing electrodes 33 difficulties, and when maintenance and recovery electrode 33, be difficult to take out.Therefore, the electrolysis unit 31 of present embodiment has the unit for treating water 60 that is installed in outer shell 2 outsides.
Unit for treating water 60 when assembling as a disposed of in its entirety, for example the same with the above-mentioned electrolysis unit of independent formation 31, have electrolytic cell 32, be arranged on the interior pair of electrodes 33 of electrolytic cell 32, from a pair of water flowing road 34,35 that electrolytic cell 32 extends out.Electrolytic cell 32 utilizes synthetic resin integrally formed with a pair of water flowing road 34,35.
Unit for treating water 60 as shown in Figure 2, the preceding side lower part that is installed in outer shell 2 is seen on the position of keeping right from the front, is arranged to utilize the bight of housing 1 and the gap between the outer shell 2.And power-on circuit 30 (with reference to Fig. 7) is electrically connected with unit for treating water 60.Power-on circuit 30 has transformer 61 etc.Usually the weight of transformer 61 is big, sees on the high strength front face 62 of keeping right, constitute housing 1 bight but be stably fixed at from the front.And transformer 61 also can be installed in the bottom 64 of outer shell 2, in this case, utilizes the big weight of transformer 61, prevents outer shell 2 vibrations ideally.
Unit for treating water 60 and transformer 61 are positioned near the maintenance opening 16 of housing 1, by maintenance opening 16, can easily carry out upkeep operations such as assembling operation, repairing and replacing, reclaim field-strip etc.And, because unit for treating water 60 and transformer 61 are closer to each other, be electrically connected easily each other.And, be fixed because unit for treating water 60 and transformer 61 are connected removably by screw, so can carry out above-mentioned operation ideally.
And, unit for treating water 60 and transformer 61 are fixed on the position of the wire element (not shown) of leaving control circuit substrate 65 and being attached thereto, described control circuit substrate 65 comprise the electronic unit of control motor rotation, for example be installed in motor 8 inside motor turn-sensitive device 24 (with reference to Fig. 7), be installed in the anti-phase drive division 23 (with reference to Fig. 7) at housing 1 left side previous section 63 places.Like this, can prevent that noise that transformer 61 grades produce from producing harmful effect to the rotation control of motor 8 when 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 here.And, if surpass 5 millimeters at interval, must apply 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 is olefin resins, for example contains 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.
The top 69 of electrolytic cell 32 has the side that tilts and uprises, and the end face of electrolytic cell 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 parts that can mark off the space by water are 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 a plurality of water flowings of at least one water flowing route road constitutes, the water flowing road more than 3 for example is set.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, and 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 a pair of water flowing road 34,35 links to each other with outer shell 2 by sealing gasket 81 as shown in Figure 3.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 it tube diametric(al) compression install under the quantitative state, 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.
The terminal 84 of electrode 33 as shown in Figure 4, the bottom surface 76 by electrolytic cell 32 is directed to the outside.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 components.
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 carry out for example test of sealing property and electrolysis performance separately 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 from 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 water that the space in the outer shell 2 and wherein holding is stayed 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,, just can if form as the unit for treating water 60 that carries out aforesaid operations easily as long as can handle as one 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, separately or with outer shell 2 actings in conjunction, it is just passable to have following function, promptly passes through 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 also 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 lateral surface 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 43, 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 arranged 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 is arranged on all bights that more bight particularly is in water ideally.
Make the distance of electrode 33 interval (D3) each other for the end of a thread is adhered to.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 stirred by rotary pulse device 7, is broken for a plurality of trickle bubbles.These trickle bubbles produce ultrasonic wave when contacting fragmentation with washings.Produce the shock wave of art of ultrasound this moment, promotes thus can improve cleaning strength attached to the peeling off of the dirt composition on the washings with the situation comparison that does not add bubble.
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 and holds the water mobile (referring to the dotted arrow among Fig. 4) that stays in the electrolytic cell 32.Particularly, tilt on the top 69 of electrolytic cell 32, 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 decide the needed voltage of electrolysis ability, can make transformer 61 miniaturizations such as electric component 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 desirable apart from electrode 33 1 ends for institute's set a distance on the horizontal direction.Make this set a 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.

Store the program of above-mentioned each washing procedure in the ROM 20a of control part 20.If washing procedure has been selected in the operation by program pushbutton group 37, just read program in the ROM 20a corresponding to this washing procedure.Then, control part 20 carries out the washing running of selected washing procedure according to various loads such as this programme-control motor 8.
Even EEPROM 93 is nonvolatile memories that no power also can be stored data, be connected to control part 20.And it is also passable that this EEPROM 93 is built in control part inside.
Figure 16 is the circuit diagram that schematically illustrates power-on circuit 30.Power-on circuit 30 is made of following: transformer 95, the 100V alternating voltage step-down of source power supply 94; Dc voltage circuit 96, by the alternating voltage of transformer 95 step-downs by the rectification smoothing, this AC voltage conversion is DC voltage, DC voltage is applied on the pair of electrodes 33; Switching transistor 97 is used for beginning and stopping to electrode 33 energisings by the operation of control part 20; Change-over switch 98 (being equivalent to inversion set of the present invention) is switched the energising direction of described pair of electrodes 33; The 3rd relay 99 is arranged between described change-over switch 98 and the switching transistor 97, by control part 20 operations.Change-over switch 98 is made of the first relay 98a and the second relay 98b of control part 20 operations, and the first relay 98a links to each other with the second electrode 33b with the first electrode 33a respectively with the second machine 98b.Swing to the contact of a side, the second relay 98b swings under the state of d side at the contact of the first relay 98a, because the first electrode 33a is an anode, the second electrode 33b is a negative electrode, if switching transistor 97 is connected, just has electric current to flow to the second electrode 33b from the first electrode 33a.On the contrary, swing to the b side at the contact of the first relay 98a, the contact of the second relay 98b is swung under the state of c side, because the second electrode 33b is an anode, the first electrode 33a is a negative electrode, just has electric current to flow to the first electrode 33a from the second electrode 33b.And the 49a of contact portion of power switch 49 is between source power supply 94 and transformer 95.
Therefore, the automatic washing machine of present embodiment, can be sterilized to washings in the rinsing washings in the washing running program that use washing agent such as standardization program wash by above-mentioned formation with electrolysis unit 31, and this is first characteristics.Below, be that example illustrates described first characteristics with the standardization program.
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, with inertia rotation institute's duration (from the pulse signal sum of turn-sensitive device 24) the corresponding definite 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, the water level (step S4) that supplies water to and set.Like this, the washing agent liquid of detergent dissolution in running water holds and stays in the outer shell 2.If supply water water level, then close the first valve 13a.
Then, control part 20 produces current by making pulsator 7 with institute's constant speed degree left and right sides both direction counter-rotating 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 fixed wash time (for example 10 minutes), pulsator 7 stops, 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).Wish in standardization program in the rinsing under the situation to the washings sterilization the user, before washing running beginning, by the setting of sterilizing of additional sterilization button 42.
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, the water level (step S10) that supplies water to and set.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, make pulsator about 7 counter-rotating rotation, the agitator treating thing carries out the not expelling water and rinsing (step S11) of washings.Like this, washings is by rinsing.If after making pulsator 7 rotation beginning rinsings, pass through fixed rinsing time (for example 2 minutes and 30 seconds), stop pulsator 7, expelling water and rinsing end.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, carry out final dewatering (step S13).This final dewatering is longer than the dewatering time of middle dehydration, so that washings fully dewaters.Then, if final dewatering 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 the rinse cycle first time.For the first time in the rinse cycle, do not carry out expelling water and rinsing at this, 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 make pulsator 7 work begun to pass through fixed rinsing time (for example 4 minutes), expelling water and rinsing finishes, 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.Therefore, 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 than water level low decide water level (for example following water level of the 2nd in the table among Fig. 9 row), beginning in rinsing to the electrolysis rinsing (step S19) of washings sterilization.Certainly, this institute decides the pair of electrodes 33 of 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.
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, decision is sterilized time of rinse cycle, 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 be controlled to be 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, reach to decide the time that concentration needs 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-rotating rotations.And, under the situation that is provided with 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.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, carry out final dewatering (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 whether the electrical current value that has just detected 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 perhaps little do not reach fixed number of times (for example 3 times) (being "No" in the step K 8), return 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 to begin whether to have crossed conduction time (2 minutes) (step K 12) of fixing time.To fix time be the energising initial stage because the rising of the electrical current value that polarity inversion produces is steadily got off the needed time.Then, fixed time 2 minutes, upper bound current value is set at for example 9A (step K 13) if crossed institute.
Then, judge whether the electrical current value surpasses upper bound current value 9A (step K 14).If surpass upper bound current value, though perhaps surpass do not reach fixed number of times (for example 3 times) (being "No" in the step K 15), if crossed the energising dwell time of determining (being "Yes" in the step K 16), return step K 1 in step K 11.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.
Before in step K 16, judging dwell time, even on electrode 33, in the energising dwell time, 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.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 this point 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 the electrical current value that before conduction time, detects (relatively the electrical current value is that energising begins to detect to fix time back), be owing to flow through dash current at the energising initial stage, current value uprises, and 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, 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, judge above upper bound current value in the step K 12 of above-mentioned energising control, and step K 13 judge reach decide number of times.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, decide reversing time as described later whenever having crossed 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 when stablizing, flow through 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, thus undesirably end the energising control of electrode 33.
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 undesirably not interrupt the energising control 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 apply 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 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, and step K 8 judge reach decide number of times.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.
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 Figure 13～Figure 15 (a), the flow chart of Figure 15 (b) illustrates the washing running work of detergent-free program.
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.
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 segmentation 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 failures 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 than water level low decide water level (for example following water level of second in the table of Fig. 9 row), beginning electrolysis prewashing (step F 3).Certainly, decide water level in this institute, 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.
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 from electrolysis prewashing began fixed prewashing time (for example 3 minutes), 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,, drop into washing agent because the user make a mistake, owing to reasons such as the detergent concentration of pre-wash water uprise, under the situation that electrical current becomes very high, the work of termination electrolysis unit 31 in electrolysis prewashing process., 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, though the dirt deleterious that comes off a little also can realize the effect of prewashing.
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 fixed dewatering time, 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, by counter-rotating rotation agitator treating thing (step F 566) if supply water.Washings is made in order like this, removes the imbalance of washings in the washing and dewatering cylinder 5.Like this, make the time in order if crossed fixed, 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.
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.In this electrolytic scrubbing process, different with the situation of prewashing process, the dirt of the washings that must fully come off.Therefore, if drop into the reason of washing agent, may lean on the effect of washing agent can guarantee washing (-)off properties, 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 conductances 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, after the dehydration (step F 14), carrying out electrolysis rinsing program (step F 15～F17) in the middle of carrying out again for the third time.
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.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 final dewatering (step F 18) of middle dehydration.The dehydration work of this final dewatering is that dewatering time is long, and is identical with middle dehydration work.Then, if final dewatering 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 the ability of cleaning.
But, under identical polarization state, give electrode 33 energisings continuously, adhere to scale on the electrode surface, there is the problem that is not easy to flow through electric current, electrolysis ability drop between the electrode.In order to prevent such situation, in the automatic washing machine of present embodiment, the polarity inversion control of the polarity of regular counter-rotating electrode 33 is finished itself in the control of control part 20, below, according to this process of the flowchart text among Figure 17.
If make electrolysis unit 31 work, promptly begin the energising control on the electrode 33, at first, from EEPROM 93, read the conduction time (step G1) on the electrode 33 when last time, energising control stopped.Then, follow and begin the conduction time of being read to continue timing conduction time (step G2).Then, judge whether reach predetermined reversing time, for example 60 minutes (step G3) conduction time of writing down.If reversing time is short, just be difficult to adhere to corresponding scale., electrode 33 frequent counter-rotatings are to be plated in the reason that the thin-film material of the formation oxidation catalyst on the electrode surface peels off.Therefore, reversing time is can prevent that scale from adhering to and can prevent the time that thin-film material peels off, and determines by experiment in advance etc.
Reach reversing time if judge, stop the energising control of electrode 33, stop to electrode 33 energisings (step G4) at step G3.Then, make the polarity (step G5) of change-over switch 98 work counter-rotating electrodes 33.For example, be anode at the first electrode 33a, the second electrode 33b is under the situation of negative electrode, and the contact of the first relay 98a switches to terminal b side from terminal a side, and the contact of the second relay 98b switches to terminal c side from terminal d side simultaneously.Like this, the first electrode 33a becomes negative electrode, and the second electrode 33b becomes anode.Like this, if polarity inversion finishes, reset conduction time, picks up counting once more, and the control that begins once more to switch on (step G6～G8).Then, return step G3.
Do not reach reversing time if judge, just judge whether the energising control of electrode 33 finishes (step G9) at step G3.If energising control does not finish, return step G3.On the one hand, if energising control is through with, stop timing conduction time (step G10).Then, being stored in (step G11) among the EEPROM 93 conduction time of so far being write down, polarity inversion control finishes.
Like this, in the automatic washing machine of present embodiment, whenever the conduction time of electrode 33 reach fixed reversing time, the polarity of electrode 33 is inverted, and prevents that scale from attached on the electrode surface, can guarantee stable washing (-)off properties and sterilization ability.
And, owing to have EEPROM 93 as nonvolatile memory, if the energising of electrode 33 control finishes, be stored among the EEPROM93 conduction time of so far being write down, if the next energising control of beginning, just from EEPROM 93, read conduction time, then begin to continue timing this conduction time,, extract the power supply that attaching plug cuts off washing machine even therefore power switch 49 is disconnected, also can remember conduction time, usually can be in certain reversed polarity conduction time.
And, as mentioned above, because electrode 33 is switched on, make the current value certain basically (on average roughly certain) that flows through electrode 33, basically be certain the conduction time that begins to adhere to before the scale, even therefore not strict adjustment reversing time also can be stablized and prevents that scale from adhering to.
