Description
Technical field
The present invention relates to a kind ofly be arranged on the rotary drum rotating in the steel ladle and will be contained in the tumbling-box washing machine that the washings in the swing roller washs by driving.
Background technology
The structure example of existing tumbling-box washing machine as shown in Figure 7.As shown in FIG., supporting steel ladle 53 by suspended structure in the washing machine body 57, be provided with swing roller 51 in the steel ladle 53, the inner barrel wall of swing roller 51 is provided with many through holes 52.Swing roller 51 is being driven by drum drive motor 55 and is rotating.The face side of washing machine body 57 is provided with switching gate 54 freely, after gate 54 is opened, just can put into washings in the swing roller 51 or therefrom taking-up by the front openings part of steel ladle 53 and the front openings part of swing roller 51.
After opening described gate 54, washings being put in the swing roller 51, dropped into washing powder again, just can start washing operation.After the operation beginning, add water earlier in steel ladle 53, the water of adding passes through hole 52 and enters in the swing roller 51, when reaching the water yield of regulation, adds water and stops.Drum drive motor 55 begins to drive swing roller 51 and rotates with predetermined rotational speed, the stirring thrust 56 that the washings that is contained in the swing roller 51 is arranged on the inner barrel wall of swing roller 51 catches on, is raised on direction of rotation, thrown again after arriving suitable height, it is cleaned by the effect that washings is applied with " beaing " washing.After washing operation was finished, dirty washings were discharged from, and used initiate water to implement the rinsing operation; Behind the rinsing EO, make swing roller 51 that rotation at a high speed take place, implement dehydrating operations.(example wherein can with reference to the 3rd~5 page in Japanese kokai publication hei 10-201985 communique and Fig. 1) be carried out in these operating process control sequence according to the rules automatically.
In such tumbling-box washing machine, when swing roller 51 remains static following time, washings can be assembled (biasing) bottom at swing roller 51.When after washing step and rinse step are finished, carrying out dehydrating operations, earlier the water in the swing roller 51 are discharged, make swing roller 51 that rotation at a high speed takes place again, make washings realize dehydration by centrifugal force.But if washings is partially in a side at this moment, the center of gravity of swing roller 51 will be in non-equilibrium state, just very big vibration may take place, and can't carry out normal dehydrating operations.Therefore, in above-mentioned existing tumbling-box washing machine, generally be controlled to earlier by following order carry out the operation that makes " cloth is rubbed out " that swing roller 51 is rotated with the 1st rotary speed, from the 1st rotary speed be increased to the 2nd rotary speed the washings balancing run, make swing roller 51 rotate the preparation dehydrating operations of the regulation number of turns and after preparation dehydration, detect the balance decision of the washings poised state under the 2nd rotary speed with the 3rd rotary speed, and then carry out dehydrating operations.
Therefore, in above-mentioned dehydration control of the prior art, very complicated in actual control operation before carrying out dehydrating operations, the time that needs is also long, so exists manufacturing cost height, the required elongated in vain problem of time of whole washing process.
In addition, at the article that have the button shape on the washings or be mixed with under the situation of article of long ribbon shape, washings is intertwined at washing and rinse cycle very intricately, and probably takes what control operation also inextricable.Because not being arranged in the existing washing machine impels the user to untie the device of the winding in the washings in this case, so washings just will dewater, therefore exist the problem that dehydrating operations interrupts easily in the process of carrying out under the state that imbalance is not eliminated as yet.
Summary of the invention
The object of the present invention is to provide and a kind ofly can be controlled at the tumbling-box washing machine that the dehydrating operations that carries out after washing and the various operating process such as rinsing carries out smoothly, also can tackle operation accordingly simultaneously under the occasion that the imbalance of washings can't be eliminated.
To achieve these goals, comprise in the tumbling-box washing machine among the present invention: rotary middle spindle is in horizontal direction basically or is in horizontal direction swing roller on the direction of inclination; Flexiblely be bearing in the washing machine body and the inner steel ladle that is provided with described swing roller; Drive the drum drive motor of rotary drum rotating; Control device with the rotation of controlling described drum drive motor.Wherein, in the dehydrating operations that in each operating process, carries out, described control device makes swing roller accelerate to earlier to make washings to be adjacent to the 1st regulation rotary speed on the bucket wall within it, and initial decision content according to the rules judges whether washings is adjacent to the washings poised state determination step on described inner barrel wall equably again; In described washings poised state determination step, determine balance when bad, carry out the operation of judging until the washings poised state repeatedly according to described initial decision content; When number of repetition reaches stipulated number, then initial decision content is changed to the change decision content that allowed band is strengthened, carry out repeatedly again until the operation till the washings poised state determination step; When determining the washings poised state according to initial decision content or change decision content when good, then swing roller is controlled to the dehydration rotary speed.
Adopt the words of said structure, in washings poised state decision process, determine under the bad occasion of balance, then repeat the start-up function of dehydrating operations with the number of times of regulation, the state of the washings in the swing roller changes easily like this, even washings under the state that is intertwined, is eliminated easily by starting also repeatedly.If more intricately is intertwined washings, to judge that by initial decision content the poised state of washings can not be judged to be balance good, initial decision content then is changed and is the wide change decision content of allowed band, like this, the phenomenon of interrupting appears in the dewatering operation course even some imbalance a little, dehydrating operations also are difficult for appearing at Once you begin.
In said structure, when the repetitive operation number of times that carries out according to after changing decision content reached stipulated number, control device then control abnormity warning device carried out abnormal alarm.Like this, even occurred the winding that control operation is not eliminated in the washings, also can impel the user to eliminate winding to the user report abnormal conditions.
In addition, determining the washings poised state according to after changing decision content when good, control device then after the rotary speed of will dewatering is controlled to beguine and determines the 2nd low dehydration rotary speed of the regulation dehydration rotary speed of washings poised state when good according to initial decision content, carries out dehydrating operations again.Like this, the situation that dehydrating operations interrupts in the time of control operation just can not occurring and do not eliminate uneven in the washings, even some imbalance a little, dehydrating operations also can go on.At this moment, because the dehydration rotary speed has dropped to the 2nd dehydration rotary speed, decline has taken place in water separation capability, and is therefore, by prolonging dewatering time, basic identical in the time of can making dewatering state and standard dehydration rotary speed.
In addition, the rotation driving direction when making swing roller accelerate to the 1st regulation rotary speed is controlled so as to when each re-lighting and all changes, and the force direction that is added on the washings can be different, so the winding state of washings is eliminated easily.
The technique effect that the present invention produces is as follows.In the dehydrating operations that tumbling-box washing machine of the present invention is implemented after operating process such as washing and rinsing, washings distribution in the swing roller that is washings poised state are judged, determining balance when bad, make the start-up function of dehydrating operations repeat the number of times of regulation, washings state in the swing roller changes easily like this, even washings is under the state that is intertwined, also eliminate easily by carrying out above-mentioned start-up function repeatedly.It is good that the words washings poised state of be intertwined in the washings intricately, the initial decision content of basis being judged can not be determined into balance, then initial decision content is changed into the wide decision content of allowed band, even therefore some imbalance slightly, dehydrating operations just is unlikely to Halfway Stopping Once you begin.Because the rotary speed of dehydrating operations of this moment is controlled so as to the 2nd dehydration rotary speed lower than the dehydration rotary speed of regulation, even therefore some imbalance, dehydrating operations also can go on.In addition, can also carry out reporting the control operation of fault among the present invention by accident warning device.Like this,, also can send abnormal alarm, impel the user to take to eliminate the measure of winding to the user even there is the winding of not eliminating by control operation in the washings.

In the above-mentioned accompanying drawing, 1 is swing roller, and 3 is steel ladle, and 5 is drum drive motor, and 16 is control device.
The specific embodiment
The primary structure of the tumbling-box washing machine in one embodiment of the present of invention has been shown among Fig. 1.Supporting steel ladle 3 by not shown hitch in the washing machine body 9, be provided with the swing roller 1 of making band round-ended cylinder shape in this steel ladle 3, the rotating shaft direction of swing roller 1 is configured to horizontal direction inclination is arranged.
Above-mentioned swing roller 1 is configured to like this in steel ladle 3, promptly is positioned at front one side of washing machine body 9 with opening portion one side of round-ended cylinder, and the bottom surface is in the back side one side of washing machine body 9, and the rotating shaft direction tilts downwards from the face side to the rear side.Swing roller 1 is being driven by the drum drive motor 5 at the back side that is installed in steel ladle 3 and is rotating.The face side of steel ladle 3 is provided with opening portion 8, is used for dropping into washings or therefrom taking out washings to swing roller 1.On the inclined plane of 8 that face with this opening portion, as to be formed on washing machine body 9 front one side, be provided with switching gate 7 freely.Because described opening portion 8 opening, gate 7 obliquely upward also is arranged on the face that tilts, therefore opens the operation during input/taking-up washings in swing roller 1 of gate 7 backs and just be easy to carry out.In addition, transparent by a part or whole gate 7 are made, just can be easy to see the working condition of swing roller 1 inside from the outside.
When swing roller 1 is arranged to as described above, can produce following advantage: the input of washings/taking-up operation is carried out easily, and the water that is added in the swing roller 1 can stockpile a side overleaf, even if the water yield seldom also can reach darker water storage state, can realize water saving.But also can produce following problem simultaneously, that is, the washings that is contained in the swing roller 1 will accumulate in minimum bottom, position, so just is difficult to make the various washings in the bucket to replace, and is difficult for all washings are applied with uniform cleaning action.In addition, in dewatering operation course, washings also is difficult to realize being adjacent to equably the state on the inner barrel wall of swing roller 1.In order to solve such problem, in the present embodiment by a plurality of stirring thrusts 6 on the inner barrel wall of swing roller 1 being designed to special shape and making washings realize transposition by the rotation drive controlling that 5 pairs of swing rollers of drum drive motor 1 carry out.
In detail, described stirring thrust 6 is made into such shape, promptly with the direction at the angle of inclination that becomes regulation with the rotating shaft direction of swing roller 1 on have very long head portion, when swing roller 1 rotation, can produce the effect that the washings that makes on the lower position that is biased in the swing roller 1 moves to the position higher position effectively.When the swing roller 1 that such stirring thrust 6 is installed on a plurality of positions of inner barrel wall is being driven when rotating, the washings that is biased in lower position one side in the swing roller 1 that is obliquely installed will be pushed to higher position one side, therefore, even swing roller 1 is inclined to set, washings can not be biased in the low side in the swing roller 1 yet, can be stirred fully, the transposition of washings and mixed also can be very abundant, the phenomenon that cleaning performance descends can not take place.In addition, more after a little while, amount of liquor also can be less, reaches soaking state equably in order to make all washings, need stir fully washings, and it is replaced fully in the amount of washings.In the present embodiment, because the transposition of washings is carried out very fully, the phenomenon of therefore cleaning the effect inequality can alleviate, and cleaning performance can be improved.
Control system in the tumbling-box washing machine with said structure has been shown among Fig. 2.Wherein, the operation of tumbling-box washing machine is controlled by control device 16, and control device 16 can be controlled the operation of drum drive motor 5, water intaking valve 12 and draining valve 11.The outer surface of washing machine body 9 is provided with input setting device 17 and display unit 18, during from 17 selections of input setting device, input operation pattern, to demonstrate selected state and mode of operation in the display part 18,16 of control device are controlled the operation of drum drive motor 5, water intaking valve 12, draining valve 11 in order according to control program.Below with reference to Fig. 1~Fig. 3, the operational circumstances of the tumbling-box washing machine controlled by control device 16 is described.
During laundry, at first open gate 7, in swing roller 1, drop into washings, drop into washing powder, push " power supply is opened " button 17f on the guidance panel shown in Fig. 3 then, connect power supply, begin operation from the washing powder input port that is located on the water unit 15 into.According to the selected operator scheme of the kind of washings, started by press/pause button 17e imports the instruction of beginning laundry operations then from input pattern selector button 17d, and control device 16 promptly begins operation control.The operation of tumbling-box washing machine is carried out according to the order of washing operation stroke, rinsing operational stroke, dehydrating operations stroke basically, is being provided with under the occasion of clothes drying function, also implements (or not implementing) drying operational stroke according to user's requirement.
After laundry operations began, control device 16 at first sent to drive circuit 22 and drives the control instruction of swing roller 1 with the predetermined rotational speed rotation, to detect the washings amount of putting in the swing roller 1.Drive circuit 22 index drum drive motors 5 are rotated, and then driven rotary cylinder 1 rotation, detect washings amount by drum drive motor 5 is that be subjected to the corresponding load condition of washings amount by clothing amount detecting device 27.
Particularly, drum drive motor 5 is a dc brushless motor, drive circuit 22 as shown in Figure 2 like that the switch element 23a~23f of frequency converter 23 is carried out switch control, again by 23 pairs in frequency converter constitute 3 phase winding 5a of the stator of drum drive motor 5, energising/outage of 5b, 5c is controlled.Mains supply 28 is re-supplied in the described frequency converter 23 after being rectified into direct current by diode-bridge circuit circuit 29, choking-winding 30, smmothing capacitor 31.Because the load condition that drum drive motor 5 bears is directly proportional basically with input current, and the voltage of Weight detector 24 by resistor 25 two ends of current detection circuit 26 from the direct-current power supply circuit that is connected on frequency converter 23 can detect such current value, so clothing amount detecting device 27 just can detect the washings amount of putting in the swing roller 1 according to above-mentioned input current value.Clothing amount detecting device 27 detected washings amounts also will be used in the control operation of back, are therefore stored in the memory that is located in the control device 16.
Next, control device 16 sends the control instruction of opening water intaking valve 12 to load drive device 20, water intaking valve 12 is opened, from adding running water with water inlet unit 15 joining water supply hoses; The running water that adds on one side with put into water unit 15 in washing powder mixed mutually, Yi Bian be added in the steel ladle 3.The flooding time that adds water in steel ladle 3 is set to corresponding with clothing amount detecting device 27 detected washings amounts.Simultaneously, the water level that is added to the water in the steel ladle 3 is detected by the condensate tank of dehumidifier 19 that is located in the steel ladle 3, when reaching predetermined water level, the water level detecting signal of regulation will take place to control device 16 in condensate tank of dehumidifier 19, control device 16 will send the control instruction of cutting out water intaking valve 12 to load drive device 20, and making into, water stops.Be added to water in the steel ladle 3 and can pass the washings that the through hole 2 that is located at swing roller 1 is installed in the swing roller 1 and suck, the water levels in the steel ladle 3 can descend, and therefore also need to replenish to add water.The operating process that replenishes when adding water is identical with top operating process.
Through above-mentioned add the water management operation after, just begin to carry out washing operation.After washing operation begins, control device 16 will send the control instruction that is driven swing roller 1 rotation by drum drive motor 5 to drive circuit 22.Swing roller 1 at first is being driven with predetermined rotational speed and is rotating official hour on positive veer, afterwards, the driving of in official hour, stopping the rotation, then, be driven in and rotate official hour on the reverse directions, and then in the official hour driving of stopping the rotation.Such control operation constitutes a circulation, is called " the 1st stirs control operation " below, and the 1st such stirring control operation constantly repeated in the time of setting.Above-mentioned regulation rotary speed is set to washings and can carries out on the speed of following motion: promptly the washings a plurality of locational stirring thrust 6 that can be arranged on the internal face of swing roller 1 catches on and along with the rotation of swing roller 1 is mentioned along direction of rotation, and the height and position that surpasses centrifugal force from deadweight is thrown again.When throwing again after washings is raised earlier, washings is beaten generation the effect of washing.When such motion constantly repeats, just can produce the effect that dirt is cleaned up from the washings that has sucked washing powder solution.In addition, can from the washings heap, release, therefore can also produce the effect that makes washings generation transposition owing in the washings that overlaps, having only with stirring thrust 6 contacted those clothings.When the rotary speed of swing roller 1 is slower than predetermined rotational speed, stirs thrust 6 and just washings can not be mentioned; And when the rotary speed of swing roller 1 was faster than predetermined rotational speed, action of centrifugal force will increase, and the washings that is raised just can enter and can not issue the state of giving birth in its deadweight effect.In addition, by the direction of rotation of conversion swing roller 1, the winding that can also suppress to produce in the washings, the transposition process also can be carried out expeditiously.
To be installed to the influence of the washings amount in the swing roller 1 very big owing to washings being mentioned, throw the clean result of knocking that produces, and therefore better control method is that above-mentioned regulation rotary speed is changed according to the amount of washings.Particularly, swing roller 1 interior washings amount has been detected by above-mentioned clothing amount detecting device 27 and quilt has been stored owing to be contained in, therefore, the amount of washings than predefined ormal weight for a long time, the above-mentioned regulation rotary speeies of 16 of control device control slow down; On the contrary, when the washings amount of storage than predefined ormal weight after a little while, the above-mentioned regulation rotary speed of 16 of control device control is accelerated.Though the words that constantly repeat in described the 1st stirring control operation of the wash time inner control of regulation can reach the effect of washing while washings is replaced, but, control operation is stirred in below implementation the 1st stirring control operation and then the implementation the 2nd in official hour earlier, can reach better effect.
Stir in the control operation the 2nd, swing roller 1 is being driven earlier to stir regulation rotary speed fast in the control operation towards positive veer rotation official hour than the 1st, the driving of in official hour, stopping the rotation then, then be driven in reverse directions with the identical regulation rotary speed rotation official hour of positive veer, the driving of in official hour, stopping the rotation again.Such control operation also constitutes a circulation, and such circulating in the official hour constantly carried out repeatedly.This 2nd regulation rotary speed that stirs in the control operation is set to such rotary speed, i.e. during swing roller 1 rotation, washings is adjacent on the inner barrel wall of swing roller 1 under action of centrifugal force.By washings is adjacent on the inner barrel wall of swing roller 1, be block washings also tensible become deployed condition, at the appointed time to, rotation when stopping, the washings that turns to the top of swing roller 1 can separate, fall from the inner barrel wall of the swing roller 1 that rotating because of the effect of inertia.By making washings carry out such motion of stretching, falling again then because of being adjacent to, transposition and change of shape can take place in washings, knock cleaning function and also can bring into play effectively.
Stir these two kinds of control operations of control operation by alternatively carry out the above-mentioned the 1st and the 2nd in the time want, not only make washings that front and back position can take place swing roller 1 in and exchange, simultaneously also can to washings produce motion mode different knock cleaning function.Therefore, skewed even swing roller 1 is arranged to, cleaning performance can not descend yet, and can produce impartial cleaning performance to all washings.
Through after the above-mentioned operation, washing operation finishes.Control device 16 sends the control instruction of opening draining valve 11 to load drive device 20, carries out the draining control operation that washings dirty in the steel ladle 3 are discharged.Then, thus control device 16 to drive circuit 22 send make drum drive motor 5 at a high speed rotation make washings contained in the washings that the control instruction of dehydration take place, carry out the dehydrating operations after the washing step.
After dehydrating operations was implemented official hour, control device 16 was shut draining valve 11, opens water intaking valve 12, added new running water in steel ladle 3, began to carry out the rinsing operating procedure.In rinse step, also be driving swing roller 1 successively just change, conversion direction of rotation and is rotated between the reverse directions, carry out stirring operation, stir control operation and/or the 2nd stirring control operation by carrying out the 1st in the above-mentioned washing step, equally also make the exchange of washings occurrence positions, the effect of knocking washing can affact on all washings equably, thereby can realize not having the rinsing operation of rinsing inequality.
As shown in Figure 4, after washing operation, to carry out 2 rinsings operation usually, after each rinsing operation, also to carry out dehydrating operations, water contained in the washings is dewatered, and the dehydrating operations in the 2nd the rinsing operation is formal dehydrating operations stroke.In other words, dehydrating operations be (comprising in the aforesaid washing step) thus carry out as draining after, making swing roller 1 rotate the operation of dewatering from washings at a high speed.In stroke,, need make washings become the state that is adjacent to equably on the inner barrel wall of swing roller 1 at each, water contained in the washings is thrown in the steel ladle 3 from through hole 2 under action of centrifugal force in order to carry out dehydrating operations reliably.Not only can not successfully dewater because washings is biased at swing roller 1 under the state of a side, and rock or vibrate, therefore, when dehydrating operations begins, need implement dehydration starting and operate because of the position of centre of gravity deflection can make swing roller 1.Control procedure for dehydrating operations describes below by Fig. 5.
Fig. 5 shows the control procedure of the start-up function of the dehydrating operations of carrying out in the control device 16.Wherein, at each control step place target sequence number S1, S2 ... be the number of steps in the control procedure, and be consistent with label in the specification.
After dehydrating operations begins, at first set the initial decision content (S1) be used to judge that the washings poised state is whether good, to judge number of repetition initialization (N=1) (S2), then, the rotating speed of drum drive motor be raised speed the 1st regulation rotary speed (for example 590 rev/mins) (S3).Drum drive motor 5 raises speed the desired time of the 1st regulation rotary speed according to being controlled by clothing amount detecting device 27 data detected and that be stored in the control device 16.As shown in Fig. 6 (a), when the washings amount more for a long time, the rotary speed of drum drive motor 5 is increased to the 2nd regulation rotary speed (for example 40 rev/mins) earlier at the 1st stipulated time t1 place, and before arriving the 2nd stipulated time t2 during in keep this rotating speed, to the 3rd be increased to the 1st regulation rotary speed in the time till wanting time t3; And when the amount of washings is less, then as shown in Fig. 6 (b), is controlled to the 2nd stipulated time t2 was shortened to the time that reaches the 1st regulation rotary speed (t2~t3 ').By carrying out such control, the centrifugal force that acts on the washings will be greater than gravity, and washings will be easy to become the state that is adjacent on the inner barrel wall of swing roller 1.
If washings is the state that is adjacent to equably on the inner barrel wall of swing roller 1, swing roller 1 will normally rotate, and uneven phenomenon can not occur rotating.Therefore, in washings poised state determination step (S4), it is good to be judged to be balance, and control device 16 will carry out dehydrating operations (S14) by making drum drive motor 5 that rotation at a high speed take place, thereby make the washings dehydration.
Above-mentioned washings poised state judgement is undertaken by the uneven situation of the rotation that detects swing roller 1.As shown in Figure 2, on the stator in the drum drive motor 5 that constitutes by dc brushless motor, be provided with position detecting device 21a, the 21b, the 21c that constitute by Hall element, the interval that has electric phase angle 120 degree between these position detecting devices 21a, 21b, the 21c, and be located at epitrochanterian permanent magnet and face.When rotor 1 rotation, the magnetic field of described permanent magnet will be detected by position detecting device 21a, 21b, 21c, and with interval output pulse signal in control device 16 of electric phase angle 120 degree.Control device 16 switches the conduction and cut-off state of switch element 23a~23f according to such pulse input signal, the 1st winding 5a, the 2nd winding 5b of stator and the energising situation of the 3rd winding 5c are controlled, and the magnetic field that produces by the 1st winding 5a, the 2nd winding 5b, the 3rd winding 5c makes the rotor rotation.In addition, what switch element 23a, 23c, 23e were carried out respectively is PWM (pulsewidth modulation) control, comes rotor speed is controlled by the repetition rate control energising ratio with regulation.In addition, control device 16 calculates rotor speed from the pulse period of 3 position detecting device 21a, 21b, 21c output, rotor speed is controlled to the rotating speed that configures by switch element 23a, 23c, 23e are carried out pulsewidth modulation.Therefore, remain in rotary speed under the state of predetermined rotational speed swing roller 1, if the pulse of position detecting device 21a, 21b, 21c is not exported with the interval of regulation, then can judge: the uneven state of rotation has taken place in the swing roller 1, that is washings being adjacent on inner barrel wall is not in good state, the washings poised state is bad.Therefore, be set at washings poised state decision content, just can detect the non-equilibrium state of the washings in the swing roller 1 by amplitude of variation with the rotary speed of drum drive motor 5.
Rotation uneven state that is washings have taken place in the swing roller 1 be deflected condition if determine in described washings poised state determination step (S4), 16 of control device make swing roller 1 rotation stop (S5), to judging whether number of repetition N has reached the 1st stipulated number and (for example, N=16) judged (S6).If do not reach the 1st stipulated number, then to judging whether number of repetition N reaches the 2nd stipulated number and (for example, N=8) judge (S7).If do not reach the 2nd stipulated number, will judge that then number of repetition N adds 1 (S9), return step S3 then, carry out start-up function once more.On the other hand, if find that in the determination step (S7) of described number of repetition N number of repetition has reached the 2nd stipulated number, then with decision content change (S8), make and judge that number of repetition N adds 1 (S9), turn back to step S3 then, carry out start-up function once more.
Like this, when number of repetition reaches the 2nd stipulated number,, thereby make (rotation speed change) allowed band in the judgement of washings poised state become big with the decision content change.Therefore, even if some imbalances are arranged slightly, dehydrating operations also will begin to carry out, and with regard to not being prone to dehydrating operations the situation of interruption take place in the process of carrying out like this.
When by after repeating above-mentioned operation, step S4 determines the balance of cloth when good, judge to repeating whether times N is to judge (S11) more than 9 or 9, if number of repetition is not more than 9 or 9, then decision content did not carry out correction, therefore (for example with the dehydration rotary speed of regulation, 900 rev/mins) carry out dehydrating operations (S14), make the washings dehydration.
On the other hand, if find that in step S11 number of repetition is more than 9 or 9, then show: decision content had carried out correction for the allowed band that enlarges the judgement of washings poised state, and swing roller 1 is in the state of easy generation vibration owing to its inner washings has biasing.Therefore, the dehydration rotary speed is set to the 2nd dehydration rotary speed (for example 800 rev/min) lower than the dehydration rotary speed of regulation and goes up (S12), simultaneously, and with respect to the decline of water separation capability, correspondingly dewatering time is prolonged (S13), and then carried out dehydrating operations (S14).
In addition, even after step 8 pair decision content has carried out revising that is has enlarged allowed band during the washings poised state is judged, still judge in the step 4 under the bad occasion of washings poised state, that is to say whether judgement number of repetition N (is for example being reached the 1st stipulated number, N=16) discovery has reached under the occasion of stipulated number in the determining step (S6), then be judged to be: even the words that start-up function repeats, the state of washings can not improve yet, and washings is in the state that intricately is intertwined.At this moment, just send fault alarm, eliminate states such as winding (S10) in the washings to impel the user by modes such as electronics sound and synthetic videos.Here, though do not illustrate among the figure, the operations such as winding in the elimination washings that the user carries out can be judged by the switching of gate 7.Therefore, when detecting gate 7, then make number of repetition N initialization, and then carry out start-up function by switching.
In addition, the above-mentioned judgement of in carrying out dehydrating operations the poised state of washings being carried out all is implemented in each operating process such as the washing shown in Fig. 4, rinsing, dehydration, that is all will carry out before the enforcement of the dehydrating operations in each operational stroke.
In addition, when accelerating to the 1st regulation rotating speed, the rotation driving direction of swing roller 1 is changed at every turn.Like this, the direction that is added to the active force on the washings at every turn all can be different, and the state that washings is intertwined is just eliminated easily.
In sum, tumbling-box washing machine of the present invention determines balance when bad in washings poised state decision process, make the start-up function of dehydrating operations repeat the number of times of regulation, washings state in the swing roller changes easily like this, even washings is under the state that is intertwined, also eliminate easily by carrying out above-mentioned start-up function repeatedly.It is good that the words washings poised state of be intertwined in the washings intricately, the initial decision content of basis being judged can not be determined into balance, then initial decision content is changed into the wide decision content of allowed band, even therefore some imbalance slightly, dehydrating operations just is unlikely to Halfway Stopping Once you begin.In addition, can also carry out reporting the control operation of fault among the present invention by accident warning device.Like this,, also can send abnormal alarm, impel the user to take to eliminate the measure of winding to the user even there is the winding of not eliminating by control operation in the washings.In addition, because the rotary speed of the dehydrating operations of this moment is controlled so as to the 2nd dehydration rotary speed lower than the dehydration rotary speed of regulation, even so some imbalance, also can carry out dehydrating operations, thereby the dehydrating operations that repeatedly carries out in each operating process such as washing, rinsing can successfully be carried out.
