Abstract
The spin dryer, for laundry, has a motor (17) to rotate the drum (5), and a weight (10) at the drum (5) wall to give an imbalance. A detector (26) registers the magnitude and location of the drum (5) loaded with laundry for drying. A detection system gives the relationship between the position of the imbalance and the position of the weight (10). A control system sets the rotation of the drum (5) to position the laundry when the value of the imbalance exceeds a nominal value and the position of the imbalance is away from the immediate environment of a location at the inner drum wall opposite the weight (10), and control the motor (17) accordingly.To prevent abnormal vibration at the time of dehydration and to prevent the extension of dehydrating time by starting a dehydrating process while speedily canceling eccentric load caused by the eccentric existence of laundry in a drum. When the detected quantity of eccentricity exceeds a prescribed value (S3) and the position of eccentric center is not located near a position facing at 180 deg. a balancer provided at one part on the inner peripheral wall surface of drum (S4), either drum rotation control for performing the rearrangement of equal distribution through the release of entire laundry (S5) corresponding to a load amount (S5) or rotation control for locating the clad of laundry at the position facing the balancer at 180 deg. (S7) by shifting and moving this clad along with the inner periphery of drum is selected. When the eccentric position faces the balancer at 180 deg., water is poured to the balancer corresponding to the eccentric quantity and the drum is balanced (S8).
Description
The present invention relates to washings is housed in the inside of cage shape cylinder.Make this cylinder make the center high speed rotary and carry out the cylinder centrifugal dehydrator of washings dehydration (centrifugal dewatering device that wherein also comprises solvent, general designation is made " centrifugal dehumidifier ") with trunnion axis.Certainly, the present invention can be used in and carry out continuously by washing dehydration, arrives dry washing machine or scrubbing-and-drying unit again.
Cylinder centrifugal dehydrator is exactly that the washings after cleaning is housed in cage shape cylinder inside, and making this cylinder is high speed rotating structure in center with the trunnion axis.One of big problem of this centrifugal dehumidifier is when making the cylinder high speed rotary exactly, because of abnormal vibrations and abnormal sound take place for the imbalance of Mass Distribution around the gyroaxis under the unequal state that is dispersed on the cylinder internal perisporium face of washings.Have in the commercially available drum-type washing drying machine of such centrifugal dehumidifier in collocation,, weight is installed around the water jacket of interior dress cylinder for suppressing above-mentioned abnormal vibrations.Therefore, this scrubbing-and-drying unit weight in past becomes very heavy, makes that the place is set is restricted, moves simultaneously or also difficulty of carrying.
To solve above-mentioned problem of abnormal vibration, several cylinder centrifugal dehydrators have been proposed always as purpose.For example open in the centrifugal dehumidifier of putting down in writing in the flat 6-254294 communique, disclosed before the dehydration running of carrying out the cylinder high speed rotary, make the method for the impartial decentralized configuration of washings on the cylinder internal perisporium by the revolution of cylinder low speed the spy.Be exactly in more detail: at first make the revolution of cylinder low speed in the short time at the utmost point, then with than this speed of gyration the speed of gyration during hurry up but than the dehydration running fully slow speed of gyration make the cylinder revolution, by the combination of this two-stage revolution control, seek the dispersion of washings.
In above-mentioned prior art, as the means that detect the inner washings biasing of cylinder, pedestal at device partly is provided with the vibration monitoring sensor, when the speed of gyration that makes cylinder rises to the high speed rotary speed of the running of dewatering, in case this vibration monitoring sensor just reduces speed of gyration to abnormal vibrations.
But,, also may not just make the impartial dispersion of washings really by a cylinder low speed revolution even adopt the such cylinder revolving-control method of above-mentioned prior art.Thereby, after attempting making the washings dispersion, make the cylinder high speed rotary by the revolution of cylinder low speed, in the occasion that abnormal vibrations still takes place, the speed of gyration recast that must reduce cylinder once more disperses washings.So, if repeatedly carry out the non-central load that the revolution of cylinder low speed disperses washings and detection cylinder high speed rotary causes repeatedly, will prolong dewatering time.
And, in above-mentioned seeking the washings equalization is dispersed in the cylinder in the method on week, when in cylinder, only accommodating the heavier clothing such as (as artificial silk) of 1 weight, can not realize impartial the dispersion, can not suppress abnormal vibrations.
On the other hand, for example in the fair 7-100095 of spy number public plate, disclosed at the additional weight of the part of cylinder internal perisporium and carried out the centrifugal dehumidifier that balance is adjusted.In this existing centrifugal dehumidifier, when weight arrives the cylinder extreme higher position,, then judge into both balances if washings is in position with respect to cylinder gyroaxis and weight subtend because of gravity, just cylinder is turned round the high speed dewatering of dividing a word with a hyphen at the end of a line by low speed and turn round.But according to the method, under the state of weight and the certain balance of washings, therefore the high speed dewatering of also may not dividing a word with a hyphen at the end of a line revolution can not prevent abnormal vibrations fully when the dehydration running.Think in addition to have only and satisfy by the weight of weight that could carry out the balance adjustment with high probability, much less, this is unpractical in the centrifugal dehumidifier of reality with tight conditions such as the washings of ormal weight are housed in the cylinder.
In such centrifugal dehumidifier, for making the mobile aptly or dispersion of washings in the adjustment of short time end balance, therefore mobile the or dispersion how promptly to suit according to the state that washs has become problem again.
The present invention finishes for solving such problem, and its purpose is, provides balance before a kind of running beginning of can doing one's utmost to suppress to dewater to adjust needed time, the rotating cylinder centrifugal dehydrator of high speed dewatering of dividing a word with a hyphen at the end of a line rapidly shortly.
For reaching this purpose, the 1st invention be characterised in that, in the cylinder that washings is housed in the cage shape, to make this cylinder be center steering with the trunnion axis, takes this to carry out to possess in the cylinder centrifugal dehydrator of dehydration of this washings
A) revolution head roll motor,
B) for make the cylinder body have non-central load the heavy hammer part of a setting of this cylinder wall,
C) the non-central load checkout gear of accommodating under the state of washings the size and location that detect the cylinder non-central load,
D) adjust the position relation of the non-central load that detects by this non-central load checkout gear and above-mentioned heavy hammer part the position discriminating gear,
E) size when the non-central load that is detected by above-mentioned non-central load checkout gear is also bigger than setting, and this non-central load is not positioned at cylinder on week, the operation controller of the revolving-control method of the cylinder that the occasion that closely be close to the subtend position of above-mentioned heavy hammer part determines according to the result of above-mentioned position discriminating gear to promote that the washings in the cylinder moves and
F) adopt revolving-control method control said motor to make the rotating rotation control device of cylinder by this operation controller decision.
In above-mentioned cylinder centrifugal dehydrator, in the balance of non-central load that heavy hammer part subtend position closely is close to, is caused by this washings on week in cylinder of washings collection and heavy hammer part and make the good occasion of all balances of cylinder, even because of dehydration makes the cylinder high speed rotary, the head of cylinder shakes also little, thereby suppresses the vibration of water jacket and outer container.Therefore, the non-central load checkout gear is accommodated washings and during with the revolution of the speed of gyration of appropriateness, is detected the size and the position of this cylinder non-central load at cylinder.The non-central load checkout gear for example can constitute like that by following: making cylinder with than centrifugal force that acts on washings and the revolution of the gravity speed of gyration that roughly speed of gyration of balance (hereinafter referred to as " balanced speed of gyration ") is higher the time, serves as that non-central load is detected on the basis with the change of the drive current of motor.The position discriminating gear is investigated its non-central load and be in what kind of position on week with respect to heavy hammer part in cylinder, for example obtain between the subtend position of heavy hammer part and the non-central load from angle.In the occasion that non-central load closely is not close in the subtend position, be necessary to make washings to move this position, but the amount that should move (angle) is different because of the position of non-central load.Therefore, operation controller for example changes the revolving-control method of cylinder according to above-mentioned deviation angle, takes this to change the amount of movement of the washings in the cylinder, makes washings promptly move on to the subtend position and closely is close to.Therefore, though owing to selected that non-central load is moved to above-mentioned subtend position and closely be close to the optimum method that not carry out, so can promptly finish non-central load and the two balance adjustment that causes of heavy hammer part of causing by washings with the shortest time.
Like this, cylinder centrifugal dehydrator according to the 1st invention, even the non-central load that causes because of the biasing of washings is in any position on week in the cylinder, this non-central load also moves to the subtend position of heavy hammer part rapidly closely is close to, and makes the balance of cylinder integral body obtain adjusting by the balance with this heavy hammer part.Therefore, the balance of cylinder is adjusted the needed time and is promptly finished with the short time, can prevent the prolongation of required time of dewatering, and then prevents to wash the prolongation of required time.Vibration and noise during the dehydration running that in addition, can suppress definitely to cause because of high speed rotary-drum revolution.
In addition, in above-mentioned cylinder centrifugal dehydrator, above-mentioned heavy hammer part can be included in a water filling device from water to this water maintaining part that go up the ducted body water maintaining part of formation and inject of cylinder wall.In such formation, the state bottom roll that does not inject the water maintaining part at water self does not have non-central load, and when by water filling device water being injected the water maintaining part, cylinder self has the non-central load corresponding to this water yield.Therefore, at first the non-central load checkout gear state that do not inject the water maintaining part at water be non-central load only cause by the biasing of the washings of accommodating state the time, detect this non-central load.Then, the position relation of position discriminating gear investigation non-central load and water maintaining part, in the occasion that non-central load closely is not close in water maintaining part subtend position, operation controller changes the cylinder revolving-control method corresponding to deviation angle, to change the amount of movement of the inner washings of cylinder.So,, just will inject the water maintaining part, carry out all balance adjustment of cylinder corresponding to the water of the amount of this non-central load size if non-central load is limited to the subtend position.
Thereby, adopt such formation, as long as the non-central load that washings is caused moves to the subtend position, the size that just can be not limited to non-central load is carried out the adjustment of cylinder balance.Take this, make the balance adjustment of cylinder become easier, just can finish the balance adjustment and begin the high speed dewatering running with the short time.
In addition, for change the amount of movement of washings according to deviation angle, above-mentioned operation controller can adopt following formation, make when cylinder is turned round better than roughly certain speed of gyration of gravity with the centrifugal force that acts on washings, the speed of gyration of this cylinder is slowed down, make this centrifugal force force of gravity that becomes also little, can change its degree of deceleration according to the result of above-mentioned position discriminating gear.When cylinder turns round with roughly certain speed of gyration also higher than balanced speed of gyration, washings is attached to cylinder internal perisporium face and cylinder turns round simultaneously, when the washings piece just will have been lifted to the top of cylinder, difference is slowed down and to be made the centrifugal force force of gravity also little, and then this washings piece is broken away from by week in the cylinder and slides into or change and fall the revolution rear.After this, when the speed of cylinder rose recovery, washings was owing to the position that moves to the revolution rear is turned round on cylinder internal perisporium face once more.If when changing the degree of deceleration of geard-down speed at this moment or deceleration time etc., rearward mobile quantitative change changes, therefore as long as by above-mentioned deviation angle appropriate change degree of deceleration, just can make non-central load move to the subtend position and closely be close to.
More particularly, above-mentioned operation controller determines minimum speed of gyration according to the result of above-mentioned position discriminating gear, reduce speed now by rising near the cylinder extreme lower position by non-central load, slow down after this minimum speed of gyration of arrival, preferably return to the speed of gyration before slowing down.The angle that departs from revolution the place ahead is big more from above-mentioned subtend position, then will set low relatively minimum speed of gyration more.After the deceleration of cylinder began, minimum speed of gyration was low more, will continue more to slow down, up to non-central load being lifted to the more moment of high position.In a word, deviation angle more the big retarding time long more, so washings to change the amount of movement at rears to four big more.
In addition, above-mentioned operation controller also can maintain the speed of gyration of cylinder the deceleration speed of gyration of regulation in the time durations that the result by above-mentioned position discriminating gear determines.At this moment, the deceleration speed of gyration is not limited to deviation angle and gets a fixed number, but what replace it is to set the time of keeping the deceleration speed of gyration after slowing down by deviation angle is suitable.This is held time in short-term, and washings is little to the amount of movement at revolution rear, prolongs and holds time, and washings is big more to the amount of movement at revolution rear.In addition, for example if cylinder is slowed down, then washings is broken away from by the cylinder internal perisporium and moves in the mode of launching to the front lower place.Therefore, move to the revolution rear really in order to make washings, when wishing in the proper range of non-central load in being present in during 1 revolution of cylinder, the deceleration of beginning cylinder.
Moreover, go up the subtend position in respect to cylinder week when non-central load and be in when approaching to turn round the position at rear, be difficult to make washings to move to desirable position by the control of slowing down of 1 time cylinder.Therefore, operation controller is preferably selected the amount of movement retarding method also littler than deviation angle, by cylinder deceleration control repeatedly, a small amount of washings is arrived the revolution rear, with close desirable position at every turn.Take this, more positively carry out desirable moving.
Can not carry out the cylinder centrifugal dehumidifier that the adjustment of cylinder balance constitutes as described above by water being injected the water maintaining part, as the method that obtains the cylinder whole machine balancing, have following two kinds: do not carry out to the water filling of water maintaining part and with washings approximate equality ground in cylinder on week decentralized configuration with method that balance is adjusted with to make weight and the balance of washing weight the method that balance adjusted of water maintaining part by the water in this water maintaining part also be above-mentioned method.Particularly in the many occasions of washings, because the mobile space of washings is narrow and small in the cylinder, it is very much difficulty that the washings piece that causes above-mentioned non-central load reason is moved along internal perisporium.
Therefore, the drum-type centrifugal dehydrator of the 2nd invention is characterised in that, in the cylinder that washings is housed in the cage shape, to make this cylinder be center steering with the trunnion axis, takes this to carry out to possess in the centrifugal dehumidifier of dehydration of this washings
A) revolution head roll motor,
B) the water maintaining part of the ducted body of a formation of cylinder wall,
C) water is injected this water maintaining part water filling device,
D) detect the amount be housed in the washings in the cylinder the load checkout gear,
E) detect the size and location of cylinder non-central load the non-central load checkout gear,
F) water is not being injected under the state of above-mentioned water maintaining part, also big and this non-central load is not positioned at and cylinder week goes up the occasion that above-mentioned water keeps the subtend position closely to be close to the size of the non-central load that is detected by above-mentioned non-central load checkout gear than setting, according to the load decision that detects by above-mentioned load checkout gear promote the cylinder cycling method that washings moves in the cylinder operation controller and
G) adopt revolving-control method control said motor to make the rotating rotation control device of cylinder by this operation controller decision.
Operation controller is according to the load that is detected by load detection device, in this load is that subtend position that the occasion below the setting gathers Zhou Shangshui maintaining part in the cylinder with washings is a purpose, on the other hand, the occasion that surmounts setting in load is so that all approximate equality of washings ground decentralized configuration Zhou Shangwei purpose in cylinder, the revolving-control method of decision cylinder.
Specifically, load is setting when following, preferably adopts the revolving-control method that washings is staggered along the cylinder inner peripheral surface, revolving-control method promptly as described above.On the other hand, when load surmounts setting, preferably select to carry out untiing of washings.After easily being disperseed, this washings seeks the impartial revolving-control method that disperses.For promoting untiing of washings, can make the revolution of cylinder get the state that stops slightly earlier, make the centrifugal force force of gravity also little speed of gyration scope counter-rotating several times again revolution of cylinder then to act on washings.That is, when the revolution of cylinder was stopped slightly, the washings that is attached to cylinder internal perisporium face dropped to cylinder bottom, therefore when making thereafter that counter-rotating is turned round several times again about cylinder, washings is stirred, and enters air in the gap of each washings, makes a part washings of winding be easy to mutually separate.So, when rising to centrifugal force thereafter and surpass the speed of gyration of gravity, washings is dispersed in cylinder on interior week with just being easy to approximate equality.
According to the cylinder centrifugal dehydrator of the 2nd such invention,, finish the balance adjustment with the short time so be not limited to the amount of washings owing to select optimum balance adjustment according to the amount of washings.Therefore, can shorten the needed time of dehydration, and then shorten the required time of washing.

Followingly describe with reference to the embodiment of accompanying drawing to centrifugal dehumidifier of the present invention.Be the formation that base description possesses the tumbling-box washing machine of the centrifugal dehumidifier that present embodiment is arranged at first with Fig. 1 and Fig. 2.Fig. 1 is the side sectional drawing of this roller washing machine, and Fig. 2 is the back perspective view of this tumbling-box washing machine major part of expression.
In the inside of outer container 1, water jacket 2 is hung and is supported on spring 3 and the shock absorber 4, and in water jacket 2 inside, 5 on the cylinder of accommodating washings is supported on the main shaft 8.In the front of outer container 1, the lid 7 that the front openings of external groove 2 opens and closes is set.Washings covers at open this accommodated cylinder 5 inside at 7 o'clock.Be provided with a plurality of limberss 6 on the perisporium of cylinder 5, the water that is given in the water jacket 2 flow in the cylinder 5 by limbers 6, and the water of being deviate from by washings in cylinder 5 disperses to water jacket 2 by limbers 6 on the contrary.On the interior week of cylinder 5, the position of per 90 ° of angles of revolution is provided with 4 baffle plates 9 of following revolution that washings is stirred up altogether.1 double its inner balancer 10 that keeps water that is made in this baffle plate 9.Be provided with water guide chamber 11 at the back side of cylinder 5, it is so that axle 8 is done the center, and is in the form of annular discs, and in interior all sides of circumference big water filling opening 12 is arranged.In water guide chamber 11, form the water injection hole 13 is communicated with balancer 10 in cylinder 5 one sides, with respect to main shaft 8 and water injection hole 13 outer groove 2 one sides of 180 ° of subtends roughly, formation osculum 14.Main shaft 8 is kept by the bearing 15 that is contained on the water jacket 2, at its front end main pulley 16 is installed.Configuration motor 17 below water jacket 2, the driving force of motor 17 conveys to main pulley 16 by motor belt pulley 18, vee-belt 19.In addition, by the water of supply admission ports 20 such as outside water channel bolt, when being injected in the water jacket 2, also emit by the water filling nozzle 23 that is located on the water jacket 2 with water injection valve 22 by balance by water-supply valve 21.On the other hand, establish draining pump 25 in the drainpipe 24 that connects water jacket 2 bottoms, the water that will remain in the water jacket 2 by driving draining pump 25 are discharged to the outside.The position of ring part on circumference at main pulley 16 is provided with opening, clipping the both sides configuration illuminating part 261 and the light accepting part 262 of this ring part.Take this, during 51 weeks of revolution of cylinder, the light that is sent by illuminating part 261 only has 1 time by opening arrival light accepting part 262.Be subjected on the basis of optical signal the detection signal (revolution sign) that passback sensor 26 outputs described later are synchronous with the revolution of cylinder 5 at this.
Below, be described in more detail with the water filling and the draining of the above-mentioned balancer 10 of Fig. 3 subtend.Fig. 3 is the summary section of expression balancer 10 and water guide chamber 11 operating states.Cylinder 5 is with more than the speed of gyration of regulation when turning round, and water is in case emit by injecting nozzle 23, and the water of emitting just enters water guide chamber 11 by water filling opening 12, locates because of centrifugal to the periphery side shifting while pass to rear surface etc.Then, shown in Fig. 3 (a), water remains on 11 periphery wall inboards, water guide chamber because of centrifugal force attaches.Because water filling opening 12 areas are big, so even because of water pressure fluctuations etc. causes the water of being emitted by water filling nozzle 23 to disperse to falling direction, its major part also flies in the water guide chamber 11 really.Balancer 10 is made for the big ducted body that also more leans on outer circumferential side with respect to main shaft 8 than water guide chamber 11.Therefore, the water that injects water guide chamber 11 enters balancer 10 inside because of centrifugal force by water injection hole 13, and shown in Fig. 3 (b), attaching the periphery wall side that remains on balancer 10 is on the internal perisporium face of cylinder 5.And also opening of osculum 14 on the outer circumferential side of water guide chamber 11, water is overflowed by this osculum 14 by water guide chamber 11, but its displacement is with to inject the water yield that imports chamber 11 more few.When the water that retains in the balancer 10 is discharged, make balancer 10 stop to remain on the extreme higher position of turning round on the circumference.So, because acting on the centrifugal force of the water in the balancer 10 disappears, so shown in Fig. 3 (c), water flows out to water guide chamber 11 by water injection hole 13, the water that accumulates in 11 bottoms, water guide chamber flows out in the water jacket 2 by the osculum 14 that is in extreme lower position on the revolution circumference just.The aperture area of water injection hole 13 and osculum 14 is little, but as long as temporary transient through balancer 10 is remained on above-mentioned position, the water in balancer 10 and the water guide chamber 11 just is discharged in the water jacket 2 fully.
Following electric formation and the action that centrifugal dehydration relative section in the above-mentioned washing machine is described with reference to Fig. 4.With the micro computer is the control part 30 that the center constitutes, and is made up of central control part 31, speed of gyration control part 32, non-central load test section 33, water filling control part 34 and load test section 35 on function.Central authorities' control part 31 comprises the memory of the running program of storing the running of dewatering in advance, got the information of size and location of relevant non-central load and the information of relevant load size by non-central load test section 33 and load test section 35, carry out processing described later, will indicate to speed of gyration control part 32 with the target speed of gyration of the corresponding motor 17 of desirable cylinder speed of gyration.
Speed of gyration control part 32 makes motor 17 remain on indicated speed of gyration with motor driving part 41 actions.When motor 17 uses induction type motor, commutator motor etc. to control the motor of speed of gyration by phase controlling, speed of gyration control part 32 is based on indicated target speed of gyration with by the speed of gyration information that is attached to the 43 suffered now of getting of winding number detector on the motor 17, calculate phase control angle, pass and motor driving part 41.Motor driving part 41 for example comprises the phase inverter control loop, according to pass and phase control angle make electrical power switching element ON/OFF such as bidirectional triode thyristor, with resulting drive current supply motor 17.
Motor current test section 42 detects the drive current that flows through in the motors 17, passes and non-central load test section 33 after being transformed into voltage value.Fig. 5 is the oscillogram that shows an example of motor current change.Among the figure, revolution sign M is the sign of the signal of 5 one gyration periods of cylinder of being obtained by above-mentioned rotary sensor 26 based on expression.When having non-central load in cylinder 5, as shown in Figure 5, motor current has and the corresponding variance components of this non-central load.The change of this motor current is corresponding with the load torque change of motor 17, and the peak-peak of motor current occurs when the internal loading moment of torsion is maximum during 51 weeks of revolution of cylinder.Generally motor current increases when non-central load makes progress by cylinder 5 bottommosts, arrives the highest and reaches maximum before.On the contrary, non-central load by 5 the highest on cylinder when downward motor current reduce, reach minimum of a value before arriving bottommost.In addition, the change of motor current vibration width of cloth L is corresponding with the size (offset) of non-central load.Fig. 6 is the curve circle of an example of expression change amplitude L and offset relation.Investigate this relation in advance and be stored in the memory, just can obtain offset by electricity change amplitude L.But because the variable of motor current not necessarily only is non-central load, so, preferably carry out the filter process that variance components by motor current only takes out the frequency content that cylinder 5 speeds of gyration closely are close in order to detect the variance components depend on non-central load accurately.
Non-central load test section 33, when the signal of input motor current variance components shown in Figure 5, during each of revolution sign M is per 1 revolution of cylinder 5 at interval in detection peak-peak and minimum peak.Calculate poor (the change amplitude L) of this maximum and minimum peak then, obtain offset with reference to the relation as shown in Figure 6 of being stored in the memory.In addition, the timing that is occurred by peak-peak or minimum peak (for example by before revolution sign M time delay) detects in cylinder 5 position of non-central load on week.
Load test section 35 guides to the cleaning stroke of washing, for example presses the amount (load) of following sequence detection washings.That is, at first, be housed in the washings of drying regime in the cylinder 5 after, the water of injection ormal weight to water jacket 2 in.Secondly, the speed of gyration (for example 55rpm) during with the cleaning stroke makes the 5 revolution stipulated times of cylinder, makes it then to stop.Promoted the suction of washings during cylinder 5 revolutions, the water level in the water jacket 2 has only reduced the part that washings absorbed water.The water level reduction for a long time of the amount of washings is also big, therefore detects this drawdown by the level sensor that is attached on the water jacket 2, serves as the amount that washings is judged on the basis with this detection limit.In addition, this load also can for example be cleaned in the control such as stroke water injection rate and utilize outside the dehydration stroke.
[control during the dehydration stroke of embodiment 1]
Now use the flow chart of Fig. 7-Figure 10, the dehydration Stroke Control of embodiment 1 in the washing machine of above-mentioned formation is described.In the following description, enumerate when diameter of cylinder is taken as 470mm numerical value as an example, but what understand easily is in the different with it occasion of diameter of cylinder, by the numerical value of suitable each speed of gyration of change, can obtain corresponding effect.
When cleaning stroke end dehydration stroke began, the washings of cylinder 5 inside was in the state that heavily amasss in its bottom.This moment, water did not inject balancer 10 completely, and self does not have non-central load cylinder.Dewater stroke Once you begin, and speed of gyration control part 32 control drive divisions 41 make motor 17 startings and make the speed of gyration of cylinder 5 rise to 80rpm (step S1), and central control part 31 judges repeatedly whether the speed of gyration of cylinder 5 arrives 80rpm (step S2).This moment cylinder 5 speed of gyration can higher than balanced speed of gyration (about 60rpm) and than the low scope of the resonant frequency (about 200rpm) of cylinder 5 in the selection that suits, but, preferably select alap value for the detection of non-central load described later.
When cylinder 5 turned round with 80rom, all washings was pressed in the state turning down of cylinder 5 internal perisporium faces because of centrifugal force is in.Washings produces the change of motor current shown in Figure 5 in the occasion of interior all upper offsets of cylinder 5, so non-central load test section 33 detects offset and eccentric position (step S3) based on this variance components.Central authorities' control part judges whether the offset that detects is regulation a (for example 350g) following (step S4).Offset is judged as setting a when following, even carry out the high speed dewatering running under its previous status, vibration and noise also can be judged as little.Therefore carry out S13, the speed of gyration of revolution control part 32 index drums 5 only makes it to rise to 1000rpm.Take this, be soaked in water in the washings because of the dehydration of dispersing of centrifugal force face.In such high speed dewatering running; for protection is easy to take place the washings that fabric damages, also can the speed of gyration of cylinder 5 be limited in higher limit below the 1000rpm by the washing procedure (for example felt (cloth group) washing procedure, dry special-purpose clothing class washing procedure etc.) of user's appointment.
In above-mentioned steps S4, if judge that when offset was bigger than setting a, central control part 31 was calculated eccentric deviation angle θ (step S5) based on the eccentric position that detects in advance and the installation site of balancer 10.As shown in figure 11, eccentric deviation angle θ be with go up in week in the cylinder 5 10 180 ° of subtend positions of balancer as 0 ° on basis, will represent as the angle of revolution by the bias of 0 ° of this benchmark towards the gyratory directions eccentric position of cylinder 5.Then, by each determination processing of following step S6-S8, eccentric deviation angle θ is placed respectively in 4 angular ranges.That is, judge that at first whether eccentric deviation angle θ is-20 °-20 ° angular range (step 6).For example, when washings is in position shown in Figure 12, be judged to be eccentric deviation angle θ be accommodated in-angular range of 20-20 ° in.At this moment, inject balancer 10, the offset of cylinder 5 integral body is reduced by water with Sq.Therefore enter step S20, carry out balancer water filling running, after the balance that obtains cylinder 5, the running of the high speed dewatering of the step of dividing a word with a hyphen at the end of a line S13.
Fig. 8 is the flow chart of an example of the balance water filling running control of expression step S20.In balance water filling running, at first make the speed of gyration of cylinder 5 rise to 130rpm (step S21).The speed of gyration of this moment can be defined as lower and can invest and make the water that injects water guide chamber 11 move to suitable speed of gyration in the such scope of appropriate centrifugal force in the balancer 10 than cylinder 5 resonant frequencies, but for the vibration that suppresses to cause because of resonance, this speed of gyration is preferably low as far as possible, and is then preferably high as far as possible for carrying out water filling rapidly on the other hand.If the speed of gyration of cylinder 5 arrives 130rpm (among the step S22 " Y "), water filling control part 34 just makes balance open (step S23) with water injection valve 22.Take this, water is emitted by water filling nozzle 23 and is slowly entered balancer 10, and remains in the balancer 10 with the state that is attached on cylinder 5 internal perisporiums because of centrifugal force.Non-central load test section 33 detects the offset of following water filling and gradually changing continuously, and central control part 31 judges repeatedly whether the offset of this detection is setting b (for example 350g) following (step S24).
Washings in the cylinder 5 to be to be pressed in the state revolution of its internal perisporium face fully, and the water yield of balancer inside slowly increases the weight increase is gone down on the other hand, and therefore motor current change amplitude L as shown in Figure 5 is gradually for a short time goes down.Step S24 is as if judging that offset is when stipulating that b is following, water filling control part 34 locking balances water injection valve 22 (step S25).Take this, stop the increase of water in the balancer 10, shown in Figure 12 (b), because the balance between the water in non-central load that the washings biasing causes and the balancer 10, the offset of cylinder 5 integral body diminishes.
On the other hand, in above-mentioned steps S6 if when judging that eccentric deviation angle θ is outside-20 °-20 ° angular range, judge then that then eccentric deviation angle θ is whether at the angular range (step S7) of 60 ° of less thaies more than 20 °.Eccentric deviation angle θ is in 60 ° of angular ranges of less than more than 20 ° the time, will slow down to set value n and be set at 50rpm (step S9).If when judging that eccentric deviation angle θ is outside the angular range of 60 ° of less thaies more than 20 °, judge then that then eccentric deviation angle θ is whether in the angular range of 120 ° of less thaies more than 60 ° (step S8).Eccentric deviation angle θ is in the angular range of 120 ° of less thaies more than 60 ° the time, will slow down to set value n and be set at 45rpm (step S10).When judging that eccentric deviation angle θ is outside the angular range of 120 ° of less thaies more than 60 °, then eccentric deviation angle θ should be in the angular range of 340 ° of less thaies more than 120 ° (20 °), and the setting value of will slowing down this moment n is set at 40rpm (step S11).
After above-mentioned steps S9, the definite setting value n that slows down of any processing of S10, S11, central control part 31 judges whether load is (the step S12) below 1/3 of rated load amount.Be judged to be load and surmount 1/3 o'clock of rated load amount, the amount that then is judged to be washings is many, with the balance adjustment of its use balancer 10, not as the balance adjustment that causes by all decentralized configuration of washings more suitable.Then, carry out washings described later and untie running (step S30), seek the impartial dispersion of the washings on week in the cylinder 5, return the detection that S1 carries out non-central load then.
Fig. 9 is the flow chart that expression step S30 unties an example of control when turning round.It is that most washings twined mutually and was difficult to mostly peel off this moment in the many relatively occasions of the amount of washings that running is untied in implementation.Therefore, at first make cylinder 5 stop or being reduced to the degree (step S31) that almost stops to turn round.Speed of gyration (about 50-55rpm) left when then making cylinder 5 with the cleaning stroke is turned gyratory directions then and is made cylinder 5 with same speed of gyration right revolution (step S33) to revolution (step S32).Then, as long as counter-rotating just finishes to untie running up to through the stipulated time (among the step S34 " Y ") about repeating.Take this agitator treating thing in cylinder 5, the washings that twines is untied, and air enters in the gap of each washings, make a part washings be easy to mutually break away from.Therefore when making the speed of gyration of cylinder 5 rise to 80rpm after returning S1, washings is easy to impartial the decomposition cylinder 5 on week, and the possibility that offset is contracted in below the setting a uprises.
In above-mentioned steps S12, judging that load is 1/3 when following of rated load amount, then be judged as to use with it and disperse the balance adjustment that causes by washings is impartial, not as the balance adjustment of using balancer 10 more suitable.Its reason is, in the few occasion of washings amount, and only 1 or be that the possibility of minority part is higher of washings, only average out with washings this moment is impossible or difficulty extremely.Therefore, carry out non-central load described later and move running, the position of washings is along the circumferential direction departed from the internal perisporium face of cylinder 5, (step S40) closely is close in the subtend position that makes eccentric position move on to equalization point 10.Turn back to step S1 then, carry out the detection of non-central load again.
Figure 10 is the flow chart that an example of running control is moved in the non-central load of expression step S40.This moment, the speed of gyration of cylinder 5 maintained 80rpm, speed of gyration control part 32 is roughly the minimum peak that is held in cylinder 5 revolutions 1 and even counts motor current between the refunding, and in cylinder turns round between 1 refunding the appearance position of this minimum peak, when minimum peak occurs in during next cylinder revolution 1 commentaries on classics (among the step S41 " Y "), the speed of gyration of index drum 5 makes it to set value n (step S42) by the deceleration that 80rpm is reduced in advance.Then, if the speed of gyration of cylinder 5 is reduced to its setting value n (among the step S43 " Y ") that slows down, just promptly make speed of gyration rise to 80rpm (step S44).
Move the mobile of washings that running causes because of non-central load and be elaborated this referring now to Figure 13 and Figure 14.Figure 13 (a) and (b), (c) represent the configuration status of the washings that eccentric deviation angle θ is different respectively, and Figure 14 (a) and (b), (c) represent the deceleration curve circle at the cylinder 5 of the washings configuration of Figure 13 (a) and (b), (c) respectively.When washings is in position shown in Figure 13 (a), judge eccentric deviation angle θ in above-mentioned steps S7 in the motherwort scope of the angle of 60 ° of less thaies more than 20 °, the setting value of slowing down is 50rpm.When deceleration front roll 5 turns round with 80rpm, cause the piece of the washings of non-central load reason to be pressed in the revolution of cylinder 5 internal perisporium faces, in the moment before above-mentioned washings piece arrives cylinder 5 bottommosts, it is minimum that the load of motor 17 becomes, and motor current shows minimum peak.After this if the speed of gyration of index drum 5 makes it to drop to 50rpm, then cylinder 5 slows down as 14 (a) shown in like that, and near eccentric position arrival moment 60 ° of rotary positions roughly, speed of gyration becomes 50rpm.Because this speed of gyration is lower than equal speed of gyration, one side is bigger than the centrifugal force that acts on washings for gravity, so this washings piece arrives 60 ° rotary position to revolution a little landing of rear (opposition side of gyratory directions) (take advantage of more this baffle plate 9 after perhaps being with by baffle plate 9 and commentaries on classics fall).Speed of gyration rises to original speed of gyration 80rpm rapidly then.Take this, washings is being attached to cylinder 5 internal perisporium faces once more and is turning round to revolution a little position of moving, rear than position shown in Figure 13 (a).As a result, because non-central load moved to benchmark and closely has been close to for 0 °, so the possibility that eccentric deviation angle θ is retracted in-20 °-20 ° the angular range uprises.In addition, at this moment, the deceleration end position is in and 60 ° of relative cylinders, 5 interior low positions, soak and washings on cylinder 5 internal perisporium faces only depend on to slow down and are difficult to move, but make it to return to hastily original speed of gyration by the acceleration after slowing down, washings just moves to the revolution rear easily.
Washings is judged eccentric deviation angle in the angular range of 120 ° of less thaies more than 60 ° in above-mentioned steps S8 when the position shown in Figure 13 (b), the setting value of slowing down n is 45rpm.With above-mentioned same,, to slow down like that shown in Figure 14 (b) by the beginning of slowing down after the extreme lower position of cylinder 5 at washings, in the time of near the position that eccentric position arrival is 90 °, speed of gyration becomes 45rpm.So, centrifugal force dies down, and the revolution rear is fallen in the commentaries on classics of washings landing formula, and speed of gyration rises to original speed of gyration 80rpm rapidly then.Take this, washings moves about 90 ° position in position shown in this Figure 13 (b) to the revolution rear and is attached to once more on the cylinder 5 internal perisporium faces and turns round.As a result, because eccentric position has moved to benchmark and closely has been close to for 0 °,, eccentric deviation angle θ uprises so being contracted in the possibility of-20 °-20 ° angular range.
When washings is in position shown in Figure 13 (c), judge eccentric deviation angle θ in above-mentioned steps S6-S8 in the angular range below 340 ° more than 120 °, the setting value of slowing down n is 40rpm.Same with above-mentioned explanation, after the washings piece is by cylinder 5 extreme lower positions, reduce speed now, to slow down by the mode shown in Figure 14 (c), in the time of near the position that eccentric position arrival is 120 °, speed of gyration becomes 40rpm.So, centrifugal force dies down, and washings slides into or changes and fall the revolution rear, and speed of gyration rises to original 80rpm rapidly then.Take this, washings turns round moving the internal perisporium face that about 120 ° position is attached to cylinder 5 once more than position shown in Figure 13 (c) to the revolution rear.Like this, eccentric position in the revolution rear greatly away from occasion, only depending on once slows down can not make eccentric position move to benchmark closely to be close to for 0 °.But, by above-mentioned repeatedly speed-down action repeatedly, a small amount of washings is departed from, finally eccentric position is brought together at benchmark and closely be close to for 0 °.
Washings is moved to the position of 180 ° of balancer 10 subtends closely be close to if move running by non-central load as mentioned above, just making that balance water filling running by step 20 obtains the equilibrium composition of cylinder 5 integral body may.
As described above, in the cylinder centrifugal dehydrator of present embodiment, when offset surmounts the value of regulation, select the equalization dispersion of washings and move running as the non-central load of prerequisite with balance water filling running according to load.Therefore, owing to selected easier balance adjustment method, can enough short time finish the balance adjustment.In addition, move in the running in non-central load, the relative position relation of the non-central load that causes according to the biasing of balancer 10 and washings makes this non-central load move to the suitable cylinder that closely the is close to balancer 10 subtend positions control of slowing down.Take this balance water filling of just dividing a word with a hyphen at the end of a line short time running.
[control during the dehydration stroke of embodiment 2]
Below, the control of the dehydration stroke of flowchart text the 2nd embodiment of use Figure 15 and Figure 16.In present embodiment 2, the control of moving relevant step S9-S11 of running and step S40 with non-central load is different with the foregoing description 1, has become step S50-S52 and step S60.Central authorities' control part 31 is calculated in step S5 after the eccentric deviation angle θ, distinguishes eccentric deviation angle θ and be included in which scope of-20 °-20 °, 20 °-60 °, 60 °-120 ° and 120 °-340 ° (20 °) in step S6-S8.Then, the occasion of t deceleration time in 20 °≤θ＜60 ° is set at 0 second, 60 °≤120 ° occasion is set at 1 second, and 120 °≤θ＜340 ° occasion is set at 3 seconds (step S50-S52).Then, if cylinder 5 revolution once during in minimum peak (among the step S61 " Y ") appears, then speed of gyration control part 32 just after this speed of index drum 5 make it to decelerate to 50rpm (step S62) by 80rpm.Then, if the speed of gyration of cylinder 5 has been reduced to 50rpm (among the step S63 " Y "), t deceleration time that then sets in above-mentioned steps S50, S51 or S52 keeps (step S64) after this speed of gyration in second, make the speed of gyration of cylinder 5 rise to 80rpm (step S65) rapidly again.
That is, in present embodiment 2, the minimum speed of gyration during deceleration is the 50rpm certain value, but keeps the time length difference of lowest surfaces rotary speed by eccentric deviation angle θ.As mentioned above, the 50rpm of cylinder 5 when revolution, washings or be scattering into the revolution rear of cylinder 5, or roll down.Therefore, deceleration time, the long more displacement to the revolution rear was big more.Figure 17 shows the amount of movement measured result of the washings piece of such change during deceleration time to the revolution rear.Amount of movement (angle) and number of times (frequency) when each, t carried out respectively slowing down the control test for 20 times deceleration time have wherein been shown load is taken as about 1kg.The moving method of washings, owing to depend on the winding of for example washing etc. to a great extent, so be not consistently to decide with move angle according to t deceleration time, but as shown in figure 17 as can be known, t deceleration time can obtain desirable amount of movement with quite high probability by change.Thereby according to the revolving-control method of present embodiment 2, even eccentric deviation angle θ difference also can make the washings piece move to balancer 10 subtend positions rapidly and closely be close to.In addition, in running program figure is moved in non-central load shown in Figure 16, in step S63, the speed of gyration of cylinder 5 begins the t counting in second after reaching 50rpm, considered that in advance speed of gyration is reduced to the t ' deceleration time of required time of 50rpm by 80rpm, is begun the counting of this deceleration time of t ' to the moment that 50rpm slows down by beginning but also can obtain.
In addition, the foregoing description is illustrated the tumbling-box washing machine that makes water, but as can be known be that the present invention is also applicable to the dry cleaner that uses petroleum solvent etc.And suit in the scope of claim record of the present invention change and correction also are fine certainly.
