The specific embodiment
Below, with regard to the embodiment of the invention in conjunction with the accompanying drawings.In addition, put on prosign for the structure identical and omit explanation with existing example.
Embodiment 1
As shown in Figures 1 and 2, the 1st motor 15 makes cylinder 1 rotation with the 1st rotational speed N 1 (for example 53rpm), washs or rinsing, and the 2nd motor 16 makes cylinder 1 rotation with the 2nd rotational speed N 2 (for example 1000rpm), dewaters.Described the 1st motor 15 and the 2nd motor 16 usefulness induction conductivities constitute, and are connected with driven pulley 19 by belt 17,18 respectively.
Driven pulley 19 has 2 kinds of speed reducing ratio, the 1st motor 15 is connected by the big driven pulley 19a of belt 17 and speed reducing ratio, the 2nd motor 16 is connected by the little driven pulley 19b of belt 18 and speed reducing ratio, and is fixed on an end is fixed on the other end of rotating shaft 4 of cylinder 1 pivot.
Control device 21 is a kind of devices that the 1st motor the 15, the 2nd motor 16 etc. is controlled, and it constitutes as shown in Figure 3.Control device 21 usefulness microcomputers constitute, and by heater the 13, the 1st motor the 15, the 2nd motor 16, feed water valve 23, draining pump 24 etc. being controlled, and the series of processes of washing, rinsing, dehydration is controlled successively with the power switching device 22 of formations such as amphicheirality's controllable silicon.Washings in 13 pairs of steel ladles of heater 3 heat, and feed water valve 23 supplies water in steel ladle 3, and the washings in 24 pairs of steel ladles of draining pump 3 carry out draining.
The device that input setting device 25 persons of being to use begin etc. to input control device 21 inputs necessary setting program, action.Display unit 26 shows through the content of input setting device 25 settings, operating state etc.Water level in 27 pairs of steel ladles of condensate tank of dehumidifier 3 detects, and the water temperature in 28 pairs of steel ladles of temperature detector 3 detects, and difference input control device 21.Speed detector 29 passes through the rotating speed of the 1st motor 15 is detected the rotating speed of cylinder 1, and input control device 21.30 pairs of memory storages data necessary etc. in a series of control is remembered.Voltage check device 31 detects the voltage of source power supply 32, and input control device 21.In addition, the 33rd, power switch.
During the washing beginning, control device 21 is imported the output signal of speed detector 29 under the state that washings is done, come head roll 1 with the 2nd motor 16 with the rotating speed (for example 600rpm) that washings is affixed on cylinder 1 inwall, opening circuit from the 2nd motor 16, the amount to the washings in the cylinder 1 detects the inertia change in rotational speed (for example change in rotational speed after 500rpm to 6 second) of back roll 1.
At this moment, because the inertia change in rotational speed of cylinder 1 changes with the tension force of belt 17,18, environment temperature etc., so to revise with the variation of the rotating speed rising of the cylinder 1 after 16 drivings of the 2nd motor (for example rotation speed change after 200rpm to 3 second).That is, when the tension force of belt 17,18 was big, the inertia change in rotational speed of the cylinder 1 after the 2nd motor 16 opens circuit was just big, and the variation that rotating speed rises is just little.In addition, when environment temperature was low, the inertia change in rotational speed of the cylinder 1 after the 2nd motor 16 opens circuit was just big, and the variation that rotating speed rises is just little.Therefore, by detecting variation and the inertia change in rotational speed that rotating speed rises, can revise the tension force of belt 17,18 and the influence of environment temperature.
In addition, because the variation that the rotating speed of the cylinder 1 after driving with the 2nd motor 16 rises, be subjected to the voltage of source power supply 32 and change, so revise by the output signal of the voltage check device 31 of detection source power supply 32 voltages.That is, when source power supply 32 voltages were high, it is big that the variation that rotating speed rises just becomes.Therefore, can revise by the output signal of the voltage check device 31 that detects source power supply 32 voltages.
In addition, control device 21 as shown in Figure 4, entered dehydration procedure after following operation before the dehydration procedure with the 2nd rotational speed N 2 head rolls 1: with the rubbing washings operation of the 1st rotational speed N 1 head roll 1; Slowly make rotating speed rise to the washings balance operation of the 3rd rotational speed N 3 (for example 100rpm) from the 1st rotational speed N 1; After the washings balance operation, use the 1st pre-dehydration procedure that drives than low the 4th rotational speed N 4 (for example 150rpm) of rotating speed corresponding to the vibration resonance point of steel ladle 3 grades; After the 1st pre-dehydration procedure, drive and the imbalance of washings detected the 1st uneven judgement operation of judgement with the 3rd rotational speed N 3; The 1st uneven judges after the operation, uses the 2nd pre-dehydration procedure that drives than high the 5th rotational speed N 5 (for example 500rpm) of rotating speed corresponding to the vibration resonance point of steel ladle 3 grades; After the 2nd pre-dehydration procedure, drive and the imbalance of washings detected the 2nd uneven judgement operation of judgement with the 3rd rotational speed N 3.
In imbalance is judged operation, at first, detect by the rotating speed of 29 pairs the 1st motor 15 of speed detector, by this detection output signal the 1st motor 15 is controlled to the 3rd rotational speed N 3, then, the angle of flow of power switching device 22 is at this moment fixed, driven the 1st motor 15.Will be by this when fixedly the angle of flow drives the 1st motor 15 rotating speed amplitude of fluctuation and a reference value relatively, judge the imbalance of the washings in the cylinder 1, change a reference value by cylinder 1 interior cloth amount.
With regard to said structure operation principle is described.Open cover 8 washings dropped into connect power switch 33 in the cylinder 1 after, when the firing switch (not shown) of input setting device 25 is operated during entry into service, after detecting the amount (cloth amount) of the washings in the cylinder 1, feed water valve 23 actions are also supplied water, just stop to supply water in case detect the water level of regulation by condensate tank of dehumidifier 27, drive the 1st motor 15.In washing procedure, contain the water supplementing water for making washings, cylinder 1 is driven by the 1st motor 15 low speed rotation simultaneously, and the washings in the cylinder 1 is raised and drops on the water surface.
At this moment,, the washings in the steel ladle 3 are heated, detect, be controlled at roughly stable temperature with temperature with washings by the water temperature in 28 pairs of steel ladles of temperature detector 3 to heater 13 energisings.When washing procedure finished, draining pump 24 moved and the washings in the steel ladle 3 is discharged.Pass through rinsing process then, in dehydration procedure, cylinder 1 is by rotation driving at a high speed, and washings is by centrifugal dehydration.
The action that cloth amount in the cylinder 1 during then, just to the washing beginning detects illustrates with reference to Fig. 5.
Washings is dropped in the cylinder 1, begin action in step 40, step 41 is by the voltage of voltage check device 31 detection source power supplies 32, and step 42 is connected the 2nd motor 16, head roll 1 with full conduction mode.In step 43, when the rotating speed of cylinder 1 is 200rpm, step 44 makes the timer starting that is built in control device 21, in step 45, in case through 3 seconds, then the rotational speed N 01 of the cylinder 1 of step 46 pair this moment detects, and the variation delta N1 that begins from 200rpm is remembered, and step 47 resets timer.Here, variation delta N1 is:
ΔN1＝N01-200。
In step 48, when the rotating speed of cylinder 1 was 600rpm, step 49 was closed the 2nd motor 16.Therefore, the rotating speed of cylinder 1 slowly reduces.This moment cylinder 1 decrease speed and the cylinder 1 of rotating speed in the amount of washings relevant, under the more situation of the amount of washings, rotating speed descends slow, under the less situation of the amount of washings, rotating speed descends soon.
In step 50, when the rotating speed of cylinder 1 was 500rpm, step 51 made the timer starting, in step 52, in case through 6 seconds, then the rotational speed N 02 of the cylinder 1 of step 53 pair this moment detects, and the variation delta N2 that begins from 500rpm remembered, here, variation delta N2 is:
ΔN2＝500-N02。
Then, by following formula cloth volume index Ga is carried out computing in step 54.
Ga＝0.75×(1-0.35(V-100))ΔN1+ΔN2
In following formula, the 1st on the right is that usefulness is revised in tension force, the environment temperature to belt 17,18, the influences such as voltage of source power supply 32, and (1-0.35 (V-100)) is the voltage correction term of source power supply 32, and V is voltage (unit is volt).The variation that the 2nd expression begins from 500rpm through the rotating speed of 6 seconds cylinders 1.According to this operation result,, judge the amount of the washings in the cylinder 1, shown in (table 1) in step 55.
[table 1]
| Cloth volume index Ga | The amount of washings |
| More than 400 | 0.5kg less than |
| More than 370 400 less than | 1.0kg |
| More than 330 370 less than | 1.5kg |
| More than 300 330 less than | 2.0kg |
| 300 less than | 2.5kg more than |
According to the amount by the washings in above-mentioned such cylinder 1 after judging, control device 21 is as (table 2) shown in, and a reference value when causing imbalance to judging because of cylinder 1 interior washings is changed.
[table 2]
| The amount of washings | A reference value |
| 0.5kg | 6rpm |
| 0.5kg above 2.5kg less than | 5rpm |
| 2.5kg more than | 4rpm |
The amount of the washings in cylinder 1 more for a long time, in case the imbalance that causes because of washings in the cylinder 1 is arranged slightly, just in dehydration procedure, produce big vibration, noise, the amount of the washings in cylinder 1 more after a little while, even the imbalance that causes because of washings in the cylinder 1 is arranged slightly, can in dehydration procedure, not produce big vibration, noise yet, by as (table 2) according to the amount of washings and change to being judged to be unbalanced a reference value, just can irrespectively suppress vibration, noise in the dehydration procedure with the amount of washings.
In addition, because during the running beginning, amount to the washings in the cylinder 1 under the state that washings is done detects, the amount of being used as the washings in the cylinder 1, so and cloth matter irrespectively can correctly detect the amount of washings, change to be judged to be unbalanced a reference value according to the amount of the washings after the correct detection, can suppress vibration, noise in the dehydration procedure.
When the amount of washings more for a long time, general clean rate, the rinsing rate in rinsing process, the dehydration rate in dehydration procedure in washing procedure is with regard to step-down.And opposite, when the amount of washings more after a little while, general clean rate, the rinsing rate in rinsing process, the dehydration rate in dehydration procedure in washing procedure just uprises.Therefore, in the amount of washings more for a long time, control than common length (for example growing 20%) by 21 pairs of wash times of control device, (for example control manyly to the rinsing number of times again, common 2 rinsings are controlled to 3 rinsings), perhaps to the rinsing time control long (for example, common rinsing was controlled to 4 minutes in 1 time 3 minutes), control (for example to dewatering time again than common length, be controlled to 9 minutes with common 7 minutes), perhaps control than common big (for example, common 800rpm being controlled to 1000rpm), then can prevent the rate of cleaning dehydrating speed, the rinsing rate, dehydration rate reduces.On the contrary, in the amount of washings more after a little while, control than common weak point (for example lacking 20%) by 21 pairs of wash times of control device, the rinsing number of times (is for example controlled fewly again, common 2 times rinsing number of times is controlled to 1 time), perhaps to the rinsing time control short (for example, common rinsing was controlled to 2 minutes in 1 time 3 minutes), control (for example to dewatering time again than common weak point, be controlled to 5 minutes with common 7 minutes), or control than common little (for example, common 800rpm being controlled to 600rpm) to dehydrating speed, then can make clean rate, the rinsing rate, dehydration rate is stable.
Below, the action the when imbalance of washings in the cylinder 1 that is used for suppressing vibration, noise in the dehydration procedure is judged illustrates in conjunction with Fig. 4.
In rubbing washings operation, connect the 1st motor 15, the speed setting of cylinder 1 in the 1st rotational speed N 1 (53rpm), is detected by the rotating speed of 29 pairs the 1st motor 15 of speed detector, and controls the 1st motor 15 by this detection output signal.When connecting, closing the 1st motor 15 and elapsed time t1, then entering washings balance operation in each stipulated time (for example, connected in 8 seconds, closed in 3 seconds).
In washings balance operation, when elapsed time t2, with the 1st rate of climb (for example, 1 second rising 5rpm) rotating speed of cylinder 1 is risen, behind the elapsed time t3, with the 2nd rate of climb (for example, 1 second rising 2rpm) that is lower than the 1st rate of climb rotating speed of cylinder 1 is risen, make cylinder 1 interior washings be affixed on the inwall of cylinder 1 equably.
At time t4, connect the 1st motor 15, drive the 2nd motor 16 and enter the 1st pre-dehydration procedure with full conducting, when the rotating speed of cylinder 1 reaches the 4th rotational speed N 4 (150rpm), close the 2nd motor 16, in case the rotating speed of cylinder 1 is N3 (100rpm), then connect the 1st motor 15, enter the 1st uneven judgement operation.At this moment, the speed setting of cylinder 1 in the 1st rotational speed N 3 (100rpm), is detected by the rotating speed of 29 pairs the 1st motor 15 of speed detector, control the 1st motor 15 by this detection output signal.
When elapsed time t5, the angle of flow of the power switching device 22 the when rotating speed with cylinder 1 is controlled at the 3rd rotational speed N 3 detects, and drives the 1st motor 15 under the angle of flow stationary state after this detects.And, detect by the rotating speed amplitudes of fluctuation of 29 pairs of this moments of speed detector, detected rotating speed amplitude of fluctuation and a reference value are compared.At this moment, a reference value is changed a reference value according to the cloth amount in the cylinder 1 that determines when running begins shown in (table 2).
When the rotating speed amplitude of fluctuation when a reference value is following, the imbalance of the washings in the cylinder 1 is just few, being judged to be available ratio drives corresponding to the 5th high rotational speed N 5 of the rotating speed of the vibration resonance point of steel ladle 3 grades, behind the elapsed time t6, close the 1st motor 15, drive the 2nd motor 16 with full conducting, enter the 2nd pre-dehydration procedure.When the rotating speed amplitude of fluctuation surpasses a reference value, be judged to be and turn back to and to crumple the washings operation with driving than the 5th high rotational speed N 5 of rotating speed corresponding to the vibration resonance point of steel ladle 3 grades.
When the rotating speed that enters the 2nd pre-dehydration procedure, cylinder 1 reaches the 5th rotational speed N 5 (500rpm), close the 2nd motor 16, when the rotating speed of cylinder 1 is N3 (100rpm), then connect the 1st motor 15, enter the 2nd uneven judgement operation.
Uneven judge in the operation the 2nd, the speed setting of cylinder 1 in the 3rd rotational speed N 3 (100rpm), is detected by the rotating speed of 29 pairs the 1st motor 15 of speed detector, and controls the 1st motor 15 by this detection output signal.When elapsed time t7, the angle of flow of the power switching device 22 the when rotating speed with cylinder 1 is controlled at the 3rd rotational speed N 3 detects, and drives the 1st motor 15 under the angle of flow stationary state after this detects.And, detect by the rotating speed amplitudes of fluctuation of 29 pairs of this moments of speed detector.
Then, rotating speed amplitude of fluctuation and a reference value after detecting are compared, when the rotating speed amplitude of fluctuation when a reference value is following, the imbalance of the washings in the cylinder 1 is just few, enters dehydration procedure even be judged to be, and vibration, noise do not increase yet, behind the elapsed time t8, enter dehydration procedure.When detected rotating speed amplitude of fluctuation surpasses a reference value, enter dehydration procedure vibration, noise greatly in case be judged to be, thereby turn back to rubbing washings operation with regard to change.
In addition, in the present embodiment, the 1st motor 15 and the 2nd motor 16 usefulness inductor motors constitute, but also commutator motor etc.
In addition, in the present embodiment, 2 operations that comprise rubbing washings operation and the 2nd pre-dehydration procedure have been described, but can have saved any one operation in rubbing washings operation and the 2nd pre-dehydration procedure at least.
Control device 21 among Fig. 3 when being surpassed setting (water level roughly reaching cylinder 1 below, for example, water column 130mm) by condensate tank of dehumidifier 27 detected water levels, does not detect cylinder 1 interior cloth amount.Other formation is identical with the foregoing description 1.
With regard to above-mentioned formation its operation principle is described.When the water levels that surpassed setting by 27 pairs of condensate tank of dehumidifier detect, the no matter any occasion that surplus water is arranged in cylinder 1 or to cylinder 1 in, drop into the washings that contains water, cylinder 1 interior washings all contains water.In this case, the water yield contained in the washings is different because of the cloth matter of washings, in case be mixed with the different washings of cloth matter, then can not be correctly the amount of washings be detected, so, can be with except the incorrect data by the amount that does not detect washings.
Control device 21 among Fig. 3, the 2nd pre-dehydration procedure (with reference to Fig. 4) before dehydration procedure comes head roll 1 by the 2nd motor 16 with the 5th rotational speed N 5 (500rpm) that is lower than the 2nd rotational speed N 2, and the cloth amount in the cylinder 1 is detected with the inertia change in rotational speed of back roll 1 that the 2nd motor 16 is opened circuit (for example, the change in rotational speed after 450rpm to 6 second).
At this moment, because the inertia change in rotational speed of cylinder 1, change, so to revise with the variation of the rotating speed rising of the cylinder 1 after 16 drivings of the 2nd motor (for example rotation speed change after 200rpm to 3 second) with the tension force of belt 17,18, environment temperature etc.In addition, because the variation that the rotating speed of the cylinder 1 after driving with the 2nd motor 16 rises, be subjected to the voltage of source power supply 32 and change, so revise by the output signal of the voltage check device 31 of detection source power supply 32 voltages.
And, the cloth amount in the detected cylinder 1 when washing begins is revised by detected cloth amount.According to this revised cloth amount, judge unbalanced a reference value in the 2nd uneven judgement operation change.Other formation is identical with the foregoing description 1.

Behind the elapsed time t6, close the 1st motor 15, drive the 2nd motor 16 and enter the 2nd pre-dehydration procedure with full conducting, after the rotating speed of connecting the 2nd motor 16 and cylinder 1 with full conduction mode becomes 200rpm, the rotational speed N 01 of the cylinder 1 to through 3 seconds the time detects, and (here to the variation delta N1 that begins from 200rpm, Δ N1=N01-200) remembers, rotating speed at cylinder 1 is 500rpm, after closing the 2nd motor 16, the rotational speed N 02 of the cylinder 1 when becoming behind the 450rpm through 6 seconds to the rotating speed of cylinder 1 detects, and (here to the variation delta N2 that begins from 450rpm, Δ N2=450-N02) remembers, by following formula computing cloth volume index Ga.
Ga＝0.75×(1-0.35(V-100))ΔN1+ΔN2
In following formula, the 1st of the right is that usefulness is revised in the influence of the tension force, environment temperature, source power supply 32 voltages to belt 17,18 etc., and (1-0.35 (V-100)) is the voltage correction term of source power supply 32, and V is voltage (unit is volt).The variation that the 2nd expression begins from 500rpm through the rotating speed of 6 seconds cylinders 1.According to this operation result,, judge the amount of the washings in the cylinder 1, shown in (table 3) in step 55.
[table 3]
| Cloth volume index Ga | The amount of washings |
| More than 350 | 0.5kg less than |
| More than 320 350 less than | 1.0kg |
| More than 280 320 less than | 1.5kg |
| More than 250 280 less than | 2.0kg |
| 250 less than | 2.5kg more than |
In the 2nd pre-dehydration procedure, washings contains water, and by detecting the amount of washings, the state that can influence vibration, noise in dehydration procedure easily detects the cloth amount at this state.
Uneven judge in the operation the 2nd, the speed setting of cylinder 1 in the 3rd rotational speed N 3 (100rpm), is detected by the rotating speed of 29 pairs the 1st motor 15 of speed detector, and controls the 1st motor 15 by this detection output signal.When elapsed time t7, the angle of flow of the power switching device 22 when cylinder 1 rotating speed is controlled at the 3rd rotational speed N 3 detects, and drives the 1st motor 15 under the angle of flow stationary state after this detects.And, detect by the rotating speed amplitudes of fluctuation of 29 pairs of this moments of speed detector.
Then, detected rotating speed amplitude of fluctuation and a reference value are compared, when the rotating speed amplitude of fluctuation when a reference value is following, the imbalance of the washings in the cylinder 1 is just few, enters dehydration procedure even be judged to be, and vibration, noise do not increase yet, behind the elapsed time t8, enter dehydration procedure.At this moment, a reference value is changed a reference value according to the amount of the washings in the cylinder 1 that determines saturation state in the 2nd pre-dehydration procedure shown in (table 4).
[table 4]
| The amount of washings | A reference value |
| 0.5kg less than | 5rpm |
| 0.5kg above 2.5kg less than | 4rpm |
| 2.5kg more than | 3rpm |
When detected rotating speed amplitude of fluctuation surpassed a reference value, dehydration procedure just was judged as vibration, noise increases in case enter, thereby turned back to rubbing washings operation.
