In addition, control device 16 at first will be carried out washings balance stroke and washings balance successively and judge stroke before being rotated cylinder cleaning stroke.In washings balance stroke, make swing roller 1 begin to rotate from roughly static state, until reaching the 2nd regulation rotating speed (for example 90 rev/min) lower, thereby washings is attached in the swing roller 1 than the 1st regulation rotating speed (400 rev/mins).The washings balance judges that stroke is under the 2nd regulation rotating speed the poised state of washings to be judged.If judge that in the washings balance poised state of finding washings in the stroke is bad, then re-execute washings balance stroke.
Explain operational circumstances in the said structure below with reference to Fig. 5~Fig. 7.During laundry, at first drop into washings in swing roller 1, operating power is connected switch 17f, selectes and the input operation pattern according to the kind of washings by pattern configuration switch 17d.Afterwards, operation start/pause switch 17e begins operation.After the operation beginning, control device 16 at first makes swing roller 1 rotation, and detects washings amount in the swing roller 1 by washings amount detecting device 27.Then, calculate needed washing powder amount, and in washing powder amount display part 18e and digital display portion 18g, demonstrate needed washing powder amount according to detected washings amount.After in the washing powder input port (not shown) that is located in the intake tunnel 13, dropping into the shown washing powder amount that goes out, on remaining time display part 18f and the digital display portion 18g will then demonstrate remaining time till the EO.
Next, begin to carry out washing stroke.Open water intaking valve 12, by intake tunnel 13 washing powder that drops into from the washing powder input port is dissolved, and meanwhile water inlet in steel ladle 3, until the water level that arrives regulation.After water inlet reaches the water level of regulation, drive swing roller 1 rotation, carry out washing stroke by motor 5.Mention along direction of rotation by the lobe plate 6 that swing roller 1 is rotated, make the washings of putting in the swing roller 1 to be arranged on the internal face of swing roller 1, make it again after being lifted to suitable height and position.By carrying out such stirring operation repeatedly, to being applied with the effect of knocking washing on the washings, thereby it is cleaned.After the wash time of having passed through regulation, open draining valve 11, by drainage channel 10 will be dirty the cleaning solution discharge.Then, make swing roller 1 dehydrating operations of rotation at a high speed, cleaning solution contained in the washings is dewatered by implementation.
, open water intaking valve 12 advance water, carry out the rinsing stroke thereafter.In the rinsing stroke, also be that the stirring operation that taken up, thrown by lobe plate 6 is carried out in rotation by swing roller 1 to the washings in the swing roller 1.After the rinsing stroke is finished, enter and make the swing roller 1 dehydration stroke of rotation at a high speed.
Fig. 5 is the main operational flowchart of this washing machine.In step 100, the dehydration stroke begins.In step 101, data N is carried out initialization (making N=1); Afterwards, in step 102, make draining valve 11 be in opening; In the washings balance stroke in step 103, motor 5 drives swing roller 1 and is rotated in the forward, Yi Bian the washings in the swing roller 1 is averaged out, Yi Bian reach 90 rev/mins speed.
Here, be elaborated with reference to Fig. 6.Curve a among Fig. 6 and c are respectively drum rotation speed and the current of electric under the lighter occasion of the load of motor 5, and curve b and d are respectively drum rotation speed and the current of electric under the heavier occasion of the load of motor 5.
As shown in Figure 6, motor 5 drives swing rollers 1 rotation, makes the rotating speed of swing roller 1 reach 40 rev/mins at time t 1, between the t2 rotating speed of swing roller 1 being controlled on 40 rev/mins, makes the rotating speed of swing roller 1 reach stable at time t1.Afterwards, bring up to the 2nd regulation rotating speed (90 rev/mins) from time t2 to the rotating speed that makes swing roller 1 t3, washings is adjacent in swing roller 1.In other words, change (90 rev/mins), make the centrifugal force that affacts on the washings, washings is adjacent in swing roller 1 greater than gravity by making swing roller 1 accelerate to the 2nd regulation inchmeal from remaining static substantially.Concrete control method (example) can be: the rotating speed of control swing roller 1 makes it to be stabilized on 40 rev/mins between initial 5 seconds earlier, afterwards, quickens for 3 rev/mins with per second, and the rotating speed with swing roller 1 is controlled on 90 rev/mins at last.
Then, washings balance in step 104 judges in the stroke (between time t3~t4 of Fig. 6), under rotating speed roughly is in the state of the 2nd regulation rotating speed (90 rev/mins) poised state of the washings in the swing roller 1 judged.That is to say, adding on the motor 5 that the rotating speed that makes swing roller 1 keeps about 90 rev/mins voltage, under voltage is fixing state, measure change in rotational speed again.When change in rotational speed is big, judge that then the state that is adjacent to of washings is bad, poised state is bad.
When judging that poised state is bad in the step 104,, swing roller 1 is stopped the rotation in step 106 through after the step 105, in step 107, on N, add 1, return step 103 then, begin to carry out again, that is carry out the operation of step 103 again to step 107 from washings balance stroke.Here, when judging in the washings balance stroke that the bad number of times of washings poised state reaches the number of times (4 times) of regulation when N=4 (that is in the step 105), then enter step 108, send exception reporting.
When judging that poised state is good in the step 104, step 109 item makes the rotating speed of swing roller 1 accelerate to 150 rev/mins from the 2nd regulation rotating speed (90 rev/mins) between the time of Fig. 6 t4~t5, in (between 1 minute) between time t5~t6 the rotating speed of swing roller 1 is controlled to remain on 150 rev/mins.Like this, can make washings carry out to a certain degree dehydration, thereby alleviate the load that is added on the motor 5 during speed-raising afterwards.
Afterwards, enter step 110, the rotating speed that makes swing roller 1 between the time of Fig. 6 t6~t7 accelerates to the 1st regulation rotating speed (400 rev/mins) from 150 rev/mins, enters swing roller and cleans stroke; In step 111, make draining valve 11 be in closed condition.Like this, cleaning the water that dehydration is come out from washings in the stroke at swing roller can stockpile, and therefore need not to be provided with special mechanism, and water is stockpiled in steel ladle 3.
Next, in step 112,, in step 113 (the time t 7 of Fig. 6), the setting rotating speed R of swing roller 1 is set at the 1st regulation rotating speed (400 rev/mins), as initial value with timer 1 zero clearing.In the time of Fig. 6 t7, when the rotating speed of swing roller 1 becomes the 1st regulation rotating speed (400 rev/mins), enter in the step 114, carry out cylinder rotation control and current of electric control.
The operational circumstances of cylinder rotation control and current of electric control is described below with reference to the sub-process shown in Fig. 7.
Step 120 beginning of drum rotation speed control from Fig. 7.In step 121, make the timer 2 zero clearing; In step 122, make the rotating speed of swing roller 1 become the FEEDBACK CONTROL of setting rotating speed R (400 rev/mins of initial values).When the timing of discovery timer 2 has surpassed 5 seconds in step 123, proceed to step 124, input is by current sensing means 24 detected current of electric I; In step 125, judge that current of electric is whether more than setting Ic.
When the load of motor 5 is light, current of electric I is no more than setting Ic like that shown in the curve c of Fig. 6, then enter step 127, return main flow.On the contrary,, current of electric I heavier when the load of motor 5 shown in the curve d among Fig. 6 like that on setting Ic the time, then enter step 126, will set rotating speed R and reduce by 5 rev/mins, enter step 127 then, return main flow.
Like this, under the lighter occasion of the load of motor 5, the rotating speed of swing roller 1 is on the 1st regulation rotating speed (400 rev/mins) being controlled in initial value between time t6~t9 shown in the curve a of Fig. 6; Under the heavier occasion of the load of motor 5, the rotating speed of swing roller 1 shown in the curve b of Fig. 6, is on the 1st regulation rotating speed (400 rev/mins) being controlled in initial value between time t7~t8 earlier then; On the time t8 after through 5 seconds, set rotating speed R and reduce by 5 rev/mins and be controlled on 395 rev/mins by making; In addition, on the time t9 after through 5 seconds, reduce by 5 rev/mins by setting rotating speed R, in 390 rev/mins of controls before the time t10.
Like this, by control motor 5, when the load of motor 5 was light, current of electric promptly had been controlled between time t6~t9 below the setting Ic shown in the curve c of Fig. 6; When the load of motor 5 was heavier, then shown in the curve d among Fig. 6, after time t9, by reducing the rotating speed of swing roller 1, current of electric was controlled in below the setting Ic current of electric.
Next, enter step 115, open water intaking valve 12, water inlet in steel ladle 3.So, under the also few occasion of water few in the washings amount, that dewater out from washings, water also can stockpile in steel ladle 3 reliably.In addition, at this moment advance water according to the setting operation time shown in the top table 1, can not be subjected to the influence of washings amount, in steel ladle 3, can stockpile the essentially identical water yield according to washings amount detecting device 27 detected washings amounts.
When the step 116 of Fig. 5 judges that the timing of timer 1 has surpassed 30 seconds, time and become t10 among Fig. 6, then enter step 117, make draining valve 11 be in open mode; Enter step 118 then, carry out the dehydration stroke,, the washings in the swing roller 1 is dewatered even also swing roller 1 quickens rotation.
In steel ladle 3, stockpiling under the state of water, clean stroke by being rotated cylinder, the rotating speed of swing roller 1 is controlled to than washings is adjacent to rotating speed height in swing roller 1 but under low the 1st regulation rotating speed (for example 400 rev/mins) of steady-state speed during than dehydration, from the water of discharging with the limbers 2 of the swing roller 1 of above-mentioned the 1st regulation rotating speed rotation just as shown in Fig. 3, sidewall 14a by rhone 14 is reflected, and bumps with the outer tube wall of swing roller 1.Like this, the current that can be reflected attached to foreign matters such as laundry granulated slag on the outer tube wall of swing roller 1, that be difficult for washing and dirt rinse out, the outer tube wall of swing roller 1 can maintain under the state of cleaning, can prevent on the swing roller 1 because of dirt forms bacterium and mildew, thereby can realize the washing cleaned.
In addition, by cleaning in the stroke water intaking valve 12 opened, in steel ladle 1, added water at swing roller, can be as shown in Figure 8 that the interior bucket surface current along steel ladle 3 is moving through the water that intake tunnel 13 adds, arrive rhone 14.At this moment, the sidewall 14a of rhone 14 can cause reflection, and the blast that produces during swing roller 1 rotation simultaneously can cause turbulent flow in water.By such reflection and turbulent flow, just can come the outer tube wall of swing roller 1 is cleaned with the water of cleaning.Like this, the periphery wall of swing roller 12 can be maintained under the state that cleans more.
As mentioned above, in the present embodiment, control device 16 is stockpiling in steel ladle 3 and is being rotated cylinder under the state of water and cleans stroke, the rotating speed of swing roller 1 is controlled at than washings is adjacent to rotating speed height in swing roller 1 but on low the 1st regulation rotating speed of steady-state speed during than dehydration, therefore, swing roller 1 can produce strong current when rotating at a high speed, these strong current can will rinse out attached to foreign matters such as the laundry granulated slag on the outer tube wall of swing roller 1 and dirt, thereby periphery wall can be maintained under the peace and quiet state.Simultaneously, can also eliminate laundry foreign matter such as granulated slag and dirt once more attached to the phenomenon on the washings in the swing roller.
In addition, because each operational strokes such as control device 16 control washings, rinsing, dehydration, and in the dehydration stroke, also carry out swing roller and clean stroke, therefore after washings carries out abundant rinsing, stockpile under the state of water in the steel ladle 3, be controlled to for example 400 rev/mins by rotating speed with swing roller 1, to produce a large amount of foams when having the washing powder composition residual, thereby the rotating speed that can eliminate blow weak, swing roller 1 is put forward not high rough sledding.
In addition, owing to also be provided with the current sensing means 24 of the electric current that detects motor 5, control device 16 can be controlled motor 5 according to the signal of sending here from current sensing means 24, and the electric current of motor 5 is in below the setting.Like this, when ratio more in the washings amount and the washings that moisture content is high is higher, water in steel ladle 3 is more to be made under the heavier occasion of the load that is added on the motor 5 thereby perhaps stockpile, can be limited for the electric current that flows at motor 5, the abnormal heating that can suppress motor 5 improves security.
In addition, because cleaning in the stroke at swing roller, control device 16 make draining valve 11 be in closed condition, swing roller cleans the water that dewaters out from washings in the stroke and can stockpile, therefore, need not to be provided with special mechanism just can make water stockpile in steel ladle 3, thereby can reduce manufacturing cost, make the washing machine of cleaning, health.
In addition, because cleaning at swing roller, control device 16 make water intaking valve 12 open, in steel ladle 3, intake in the stroke, therefore, under the less occasion of washings amount or under the less occasion of the water that dewaters out from washings, water also can stockpile in steel ladle 3 reliably.Simultaneously, the outer tube wall of swing roller 1 can clean with the water of cleaning, thereby the outer tube wall of swing roller 1 can be maintained under the state that cleans more.
In addition, because control device 16 is set the operating time of water intaking valve 12 according to washings amount detecting device 27 detected washings amounts, therefore, can not be subjected to the influence of washings amount, in steel ladle 3, stockpiled the essentially identical water yield, thereby can reduce manufacturing cost, make the washing machine of cleaning, health.
In addition, because thereby control device 16 makes swing roller 1 make washings be adjacent to washings balance stroke in swing roller 1 from roughly being in static state the 2nd regulation rotating speed lower than the 1st regulation rotating speed that raise speed successively, roughly under the 2nd regulation rotating speed, judge after the washings balance judgement stroke of washings poised state, just be rotated cylinder and clean stroke, therefore, when being rotated cylinder cleaning stroke, can on the inwall of swing roller 1, change the washings poised state by washings is adjacent to inchmeal, only under the good occasion of washings balance, just be increased to the 1st regulation rotating speed.Like this, the abnormal vibrations that causes swing roller 1 and steel ladle 3 because of the imbalance of washings can be eliminated, security of products can be improved.
In addition, because control device 16 is when the poised state of washings balance judgement stroke judgement washings is bad, to carry out washings balance stroke again, like this, can make that swing roller 1 is earlier static to get off, washings is peeled off, in washings balance stroke, washings is adjacent on the inwall of swing roller 1 once more inchmeal then, the washings poised state is changed.Only under the good occasion of washings balance, just be increased to the 1st regulation rotating speed.Like this, the abnormal vibrations that causes swing roller 1 and steel ladle 3 because of the imbalance of washings can be eliminated, security of products can be improved.
In addition, in the present embodiment, though be in the dehydration stroke after washing stroke, rinsing stroke, to be rotated cylinder to clean stroke, but, " middle dehydration stroke " that also can be between washing stroke and rinsing stroke or in the rinsing stroke, carry out in the middle of be rotated cylinder in the dehydration stroke and clean stroke, also can play same effect, produce same effect.
In addition, though there is not to be provided with the clothes drying function that makes the washings desiccation in the swing roller 1 in the present embodiment,, also can set up the clothes drying function of in steel ladle 3, sending into warm braw, making dry clothes.The present invention also can play same effect, produces same effect.
In sum, the strong current that produce when the washing machine among the present invention utilizes swing roller to rotate at a high speed will rinse out attached to foreign matter such as the laundry granulated slag on the outer tube wall of swing roller and dirt, thereby periphery wall is maintained under the clean conditions, therefore can be used in rotary middle spindle roughly is provided with the swing roller of horizontal direction or incline direction wash, in the washing machine of operations such as rinsing, dehydration.
