After coil 36,39 energisings, magnetic field occurs, magnetic field is applied to magnetic viscosity fluid 52, and the viscosity of magnetic viscosity fluid 52 improves.In detail, by making coil 36,39 energisings, pass the magnetic circuit of the middle yoke 38-of the upper yoke 33-hydraulic cylinder 24-of axle 25-magnetic viscosity fluid 52-magnetic viscosity fluid 52-axle 25, pass simultaneously the magnetic circuit of yoke 41-magnetic viscosity fluid 52-axle 25 under the middle yoke 38-of the axle 25-magnetic viscosity fluid 52-hydraulic cylinder 24-carriage 44-.Thereby the viscosity of the magnetic viscosity fluid 52 in the place that each flux passes through improves.Especially, between flux density high axle 25 and upper yoke 33, and between middle yoke 38 and the axle 25, between lower yoke 41 and the axle 25, the viscosity of each magnetic viscosity fluid 52 improves, and frictional resistance increases.
Thereby, hydraulic cylinder 24, follow above-mentioned each parts (particularly up and down two coils 36,39 and upper yoke 33, middle yoke 38 and lower yoke 41), the frictional resistance increase when above-below direction vibrate.Therefore, shown in " damping force: large " in left side among Fig. 1, it is large that the damping force of damper 23 becomes.Thereby the damping force of the damper 23 of (rotation of cylinder 10 for example reach 400 (rpm) before) became large when the dehydration stroke that the resonance of tank 6 occurs started, and avoided the generation of the resonance of tank 6, had improved the speed-raising performance of the rotation of cylinder 10.
In addition, at this moment, shown in " the uneven detection " in Fig. 1 left side, according to vibrating sensor 21,22 vibration detection signal, the rotation that detects cylinder 10 is uneven.That is, control device 5 the rotary speed that makes cylinder 10 rise at different levels in unbalanced testing result when predetermined value is following, make the rotary speed of cylinder 10 rise to secondary (next stage).Thereby control device 5 rises the rotary speed of cylinder 10 in the uneven little state of rotations of holding more reliably cylinder 10 at different levels step by step.
When detecting the rotation imbalance of this cylinder 10, control device 5 makes the damping force of damper 23 keep large and is made as certain.That is, control device 5 is between uneven detection period, and two coils 36,39 about damper 23 carry out the as mentioned above energising of the electric current of 1 (A), remain unchanged.
After the rotary speed of cylinder 10 reached 400 (rpm), control device 5 stopped the unbalanced detection of rotation of cylinder 10, made the rotary speed of cylinder 10 keep 400 (rpm) with scheduled time T.Be under the certain situation of the rotary speed of cylinder 10 in this situation, control device 5 reduces two coils 36 up and down to damper 23,39 energising and final outage.Thereby, control device 5, from " damping force variation " to shown in " damping force: little ", the damping force of damper 23 diminishes such as Fig. 1.In addition, control device 5 makes the damping force of this damper 23 reduce (variation) by reduce gradually coil 36,39 energising in for example scheduled time about 15 (seconds) with predetermined variable gradient.
And then, control device 5 as next " uneven detect " among Fig. 1 namely as Fig. 1 from the left side shown in the 2nd " the uneven detection ", the rotary speed that makes cylinder 10 is from the further imbalance detection of rising of 400 above-mentioned (rpm) (based on the unbalanced detection of rotation of the cylinder 10 of vibrating sensor 21,22 vibration detection signal).Then, this testing result is when predetermined value is following, and control device 5 rises to till secondary (for example 950 (rpm)) rotary speed of cylinder 10.
Then, control device 5 is such as more next " the uneven detection " among Fig. 1, be Fig. 1 from the left side shown in the 3rd " uneven detect ", the rotary speed that makes cylinder 10 detects (based on the unbalanced detection of rotation of the cylinder 10 of vibrating sensor 21,22 vibration detection signal) from the imbalance that 950 above-mentioned (rpm) further rise.Then, this testing result is when predetermined value is following, and control device 5 rises to till the final level (for example 1200 (rpm)) rotary speed of cylinder 10.
After this scheduled time of process, control device 5 stops the rotary actuation of cylinder 10, and rotary speed is dropped to till 0.Like this, the rotary speed of cylinder 10 drops at 0 o'clock, and this rotary speed is by the speed territory of the resonance appearance of tank 6.Therefore, control device 5 makes two coils 36,39 up and down of damper 23 again pass to the electric current of 1 (A).Thereby control device 5 namely, shown in " damping force: large ", increases the damping force of damper 23 shown in the right side of Fig. 1 such as the next one among Fig. 1 " damping force: large ", avoids the generation of the resonance of tank 6.
As described above, according to the rinsing maching of present embodiment, support the suspension 7 of the tank 6 of the cylinder 10 that is built-in with rotary actuation in the inner elastomeric of outer container 1, have the damper 23 of the vibration attenuation that makes tank 6.This damper 23 is dampers that damping force is changed.In the unbalanced detection (" the uneven detection " of the leftmost side of Fig. 1) that uneven detecting unit carries out, control device 5 makes the damping force of damper 23 keep certain.
The unbalanced detection that uneven detecting unit carries out is carried out in the rotation of cylinder 10.In the rotation of this cylinder 10, if the damping force of damper 23 changes, then the restraint of the vibration of tank 6 changes, easily at tank 6 vibration-generatings.Therefore, can't correctly carry out unbalanced detection.According to the rinsing maching of present embodiment, control device 5 makes the damping force of damper 23 keep certain in unbalanced testing.Thereby the restraint of the vibration of tank 6 does not change, and is difficult to vibration-generating at tank 6.Thereby unbalanced detection becomes accurately, also becomes accurate based on the control of this unbalanced detection.
That is, according to the rinsing maching of present embodiment, when when cylinder 10 rotation, carrying out unbalanced detection, can well control, so that the damping force of the variable damper 23 of damping force can not make a very bad impression to unbalanced detection.
In addition, according to the rinsing maching of present embodiment, when the damping force of damper 23 is changed (when " damping force " shown in Figure 1 changed), carry out under the certain situation of the rotary speed that is controlled at cylinder 10 that the damping force of this damper 23 is changed.The imbalance of and then, carrying out uneven detecting unit detects (with reference to " the uneven detection " of the centre in 3 shown in Figure 1 " the uneven detection ").
Under the non-certain situation of the rotary speed of cylinder 10, if the damping force of damper 23 changes, then because the variation of the restraint of the vibration of the unstable rotation of cylinder 10 and tank 6, at tank 6 easy vibration-generatings.Therefore, subsequently unbalanced detection can't accurately be carried out.According to the rinsing maching of present embodiment, carry out under the certain situation of the rotary speed that is controlled at cylinder 10 that the damping force of damper 23 is changed.That is, the damping force of damper 23 is changed.Thereby, be difficult to vibration-generating at tank 6.Therefore, the subsequently unbalanced detection of (damping force that is right after damper 23 changes rear) becomes accurately, and the control that detects based on this imbalance also becomes accurate.
That is, this occasion when the imbalance when carrying out cylinder 10 rotation detects, also can well be controlled, so that the damping force of the variable damper 23 of damping force can not make a very bad impression to unbalanced detection.
And, according to the rinsing maching of present embodiment, the control (control that " damping force " shown in Figure 1 changed) of the damping force variation of damper 23 is carried out with predetermined variable gradient.Here, if the damping force of damper 23 sharply changes, the impact that then occurs owing to this moment is in tank 6 easy abnormals vibrations.According to the rinsing maching of present embodiment, the control of the damping force variation of damper 23 is carried out with predetermined variable gradient, avoided the damping force of damper 23 sharply to change.Therefore, in not abnormal vibration of tank 6.Therefore, can not be subject to the impact of the repercussions of abnormal vibrations, can more accurate execution unbalanced detection subsequently.Thereby, can more accurate execution based on the control of this unbalanced detection.
In addition, in the damper 23 that suspension 7 has, in each parts that the inside of hydraulic cylinder 24 possesses, the parts at both ends up and down are upper bearing (metal) 35 and lower bearing 43, between these upper bearing (metal)s 35 and lower bearing 43, possess remaining parts (upper yoke 33, upper coil 36 and upper shuttle 37, middle yoke 38, lower coil 39 and lower shuttle 40, lower yoke 41, seal 42 etc.).That is, in the inside of hydraulic cylinder 24, can be by upper bearing (metal) 35 and lower bearing 43 back shafts 25 at both ends up and down.Thereby axle 25 is when axially relatively coming and going movement, and this axle 25 is difficult to shake, and the interval between axle 25 and the coil 36,39 is difficult to change.Thereby, act on equably magnetic viscosity fluid 52 from coil 36,39 magnetic fields that occur, the damping force of damper 23 is further changed accurately.
With respect to more than, Fig. 5 represents the 2nd embodiment, Fig. 6 represents the 3rd embodiment to Fig. 9, Figure 10 represents the 4th embodiment, Figure 11 represents the 5th embodiment.Enclose respectively prosign with the 1st embodiment with a part, it illustrates omission, and different parts only is described.
[the 2nd embodiment]
Fig. 5 represents the Control the content in the 2nd embodiment.As aforementioned, in the rinsing maching of above-mentioned formation, according to the operation of guidance panel 4, after the running beginning, control module is that control device 5 is carried out running according to the order of cleaning stroke, dehydration stroke, rinsing stroke, dehydration stroke, dry trip.
Clean in the stroke, control device 5 detects the weight detecting work (washing weight testing) of the weight (be not the capacity of washings, but the washings amount of weight meaning) of the washings of accommodating in the cylinder 10 at first.At this moment, therefore the washings of accommodating in the cylinder 10 is dried cloth (washings of dried state) for before washing.Thereby this weight detecting work is the work of dried cloth weight detecting, and the rinsing maching of present embodiment has dried cloth weight detecting function.
Dried cloth weight detecting work, for example rotation reaches the required time of predetermined rotary speed and makes the rotation of cylinder 10 inertia make the rotary speed of cylinder 10 drop to the required time till the predetermined rotary speed by the driving that stops cylinder 10 subsequently according to cylinder 10, the weight of the rotary load detection washings by motor 8.Thereby in this dried cloth weight detecting work, turn-sensitive device 57 and control device 5 play the function of washing weight detecting unit.
When this dried cloth weight detecting function carried out the detection of washing weight, control device 5 made two coils 36,39 up and down of damper 23 pass to the electric current of 1 (A), and continues this "on" position.Thereby control device 5 makes the damping force of damper 23 keep certain and maximum.
Then, control device 5 is opened feed water valve 58, carry out to the water supply work of tank 6 interior water supply, until with the corresponding water level of the washing weight that detects.The supply of the lotion of placing at not shown lotion box at this moment, is carried out simultaneously with supplying water.
After the water supply work, control device 5 is by making cylinder 10 alternately rotate at just contrary both direction with low speed, washings is mainly carried out the cleaning of " knocking is cleaned " with the corresponding time span of the washing weight that detects (dried cloth weight).During this cleaning, tank 6 is also followed the rotation of cylinder 10, mainly vibrates along above-below direction.Same movement and/or motion when therefore, suspension 7 produces with above-mentioned dehydration stroke in each one.But, the cylinder 10 during this cleaning rotate to be low speed.The movement of each one when therefore, the movement of each one is than above-mentioned dehydration stroke is little.
Thereby, at this moment, the little electric current (for example 0.5 (A)) of electric current (1 (A)) when control device 5 passes to than above-mentioned dehydration stroke to two coils 36,39 up and down of damper 23.Thereby control device 5 appropriateness improve the viscosity of magnetic viscosity fluid 52, and appropriateness increases the damping force of damper 23, suppresses the vibration of the tank 6 of this moment.
When cleaning the stroke end, control device 5 is undertaken from the drainage works of tank 6 internal drainages by draining valve 15 is opened.In this drainage works, control device 5 makes two coils 36 up and down of damper 23,39 energising is stopped (outage).Thereby at this moment, the viscosity of magnetic viscosity fluid 52 is not improved by magnetic force.Thereby the damping force of damper 23 recovers the size by the natural viscosity acquisition of magnetic viscosity fluid 52.
The explanation of the work in the dehydration stroke then and the 1st above-mentioned embodiment is same.But this dehydration stroke is to carry out with the corresponding time span of the washing weight that detects (dried cloth weight).
Then in the rinsing stroke, control device 5 by feed water valve 58 is opened, carries out to the water supply work of tank 6 interior water supply at first, until with the corresponding water level of the above-mentioned washing weight that detects (dried cloth weight).Then, control device 5 by make cylinder 10 with low speed in the alternately rotation of just contrary both direction, washings is mainly carried out the rinsing work of " knocking rinsing " with the corresponding time span of the above-mentioned washing weight that detects (dried cloth weight).Then, control device 5 is undertaken from the drainage works of tank 6 internal drainages by draining valve 15 is opened.In this rinsing stroke, control device 5 is same with above-mentioned cleaning stroke, carries out two coils 36 up and down of damper 23,39 energising.
Then the work in the dehydration stroke is identical with the explanation of the 1st above-mentioned embodiment.But this dehydration stroke is to carry out with the corresponding time span of the washing weight that detects (dried cloth weight).
Then, control device 5 carries out dry trip.In this dry trip, control device 5 also detects the weight detecting work of weight (washing weight) of the washings of cylinder 10 interior existence at first.At this moment, the washings of cylinder 10 interior existence is the state behind cleaning stroke, rinsing stroke, the dehydration stroke, therefore is wet cloth (washings of wet condition).Thereby this weight detecting work is wet cloth weight detecting work, and the rinsing maching of present embodiment also has wet cloth weight detecting function.
Wet cloth weight detecting work is carried out with the identical content with the work of aforesaid dried cloth weight detecting.When should wet cloth weight detecting function carrying out the detection of washing weight, control device 5 also passes to the electric current of 1 (A) identical with electric current in the work of dried cloth weight detecting to two coils 36,39 up and down of damper 23, and continues this "on" position.Thereby control device 5 makes the damping force of damper 23 keep certain and maximum.
Then, control device 5 with the corresponding time span of the washing weight that detects (wet cloth weight), carry out the drying work that makes the washings drying by making cylinder 10 rotations and drying unit 17 being worked.At this moment, during the cleaning of control device 5 and above-mentioned cleaning stroke and same during the rinsing work of rinsing stroke, to two coils 36 up and down, 39 energisings of damper 23.
Like this, in the present embodiment, rinsing maching has the dried cloth weight detecting function that detects its weight when washings that the inside of cylinder 10 exists is dried cloth.When this dried cloth weight detecting function carries out the detection of washing weight, make the damping force of damper 23 keep certain.Thereby during dried cloth weight detecting, the restraint of the vibration of 23 pairs of tanks 6 of damper does not change, and is difficult to vibration-generating at tank 6.Thereby cylinder 10 can be stablized rotation, and therefore, the detection of the washing weight that dried cloth weight detecting function carries out (dried cloth weight) also can accurately be carried out, and also can accurately carry out based on the control of the detection of this washing weight.
That is, according to the rinsing maching of present embodiment, when carrying out the detection of weight of washings (dried cloth), can well control, so that the damping force of the variable damper 23 of damping force does not make a very bad impression to the detection of the weight of washings.
In addition, in the present embodiment, the washings that rinsing maching has the inside existence of cylinder 10 is the wet cloth weight detecting function that detects its weight when wetting cloth.When this wet cloth weight detecting function carries out the detection of washing weight, make the damping force of damper 23 keep certain.Thereby during wet cloth weight detecting, the restraint of the vibration of 23 pairs of tanks 6 of damper does not change yet, and is difficult to vibration-generating at tank 6.Thereby cylinder 10 can be stablized rotation, and therefore, the detection of the washing weight that wet cloth weight detecting function carries out (wet cloth weight) also can accurately be carried out, and also can accurately carry out based on the control of the detection of this washing weight.
That is, according to the rinsing maching of present embodiment, when carrying out the detection of weight of washings (wet cloth), can well control, so that the damping force of the variable damper 23 of damping force does not make a very bad impression to the detection of the weight of washings.
And, in the present embodiment, when above-mentioned 2 kinds of washing weight testings (washing weight of dried cloth detects and the washing weight of wet cloth detects), make the damping force of damper 23 keep certain and maximum.
Here, when the detection of the washing weight of dried cloth, washings is not limited to dried cloth, may add dried cloth in wet cloth (such as moisture many bath towels etc.).In addition, when the detection of the washing weight of wet cloth, the wet cloth that washings is not limited to dewater especially in the occasion of only carrying out separately dry trip etc., may add at the wet cloth (moisture many wet cloth) of not dehydration the wet cloth (moisture few wet cloth) of dehydration.When under such state, making cylinder 10 rotation, produce easily uneven.
According to present embodiment, detect arbitrary occasion of (washing weight of dried cloth detects and the washing weight of wet cloth detects) at above-mentioned 2 kinds of washing weights, all make the damping force of damper 23 certain and maximum.Therefore, when the detection of these washing weights, the vibration of the tank 6 that can the above-mentioned imbalance of establishment causes.Thereby, can make cylinder 10 more stable rotations, the more accurate detection of carrying out washing weight.Thereby, by present embodiment, also can the more accurate control of carrying out based on the detection of washing weight.
[the 3rd embodiment]
Fig. 6 represents the Control the content in the 3rd embodiment.As aforementioned, in the rinsing maching of above-mentioned formation, according to the operation of guidance panel 4, after the running beginning, control module is that control device 5 is according to the sequential operation of cleaning stroke, dehydration stroke, rinsing stroke, dehydration stroke, dry trip.
As mentioned above, clean in the stroke, control device 5 carries out weight detecting work (especially dried cloth weight detecting work) at first.
During this dried cloth weight detecting work, follow the rotation of cylinder 10, tank 6 mainly vibrates along above-below direction.
Thereby control device 5 passes to the electric current of predetermined value (this occasion is 1 (A)) to two coils 36,39 up and down of damper 23 when this dried cloth weight detecting work, continue this "on" position.
Thereby especially, between the high axle 25 of flux density and the upper yoke 33 and between middle yoke 38 and the axle 25, between lower yoke 41 and the axle 25, the viscosity of magnetic viscosity fluid 52 improves, and frictional resistance increases.
Thereby hydraulic cylinder 24 is followed each parts (two coils 36 especially up and down, 39 and upper yoke 33, middle yoke 38 and lower yoke 41), the frictional resistance increase when above-below direction vibrate.Therefore, damping force increases.Thereby the restraint of the vibration of 23 pairs of tanks 6 of damper does not change, and is difficult at tank 6 vibration-generatings, and therefore, the detection of the washing weight that dried cloth weight detecting function carries out also can accurately be carried out.
Then, control device 5 carries out water supply work, then, carries out cleaning.During this cleaning, also follow the rotation of cylinder 10, tank 6 is mainly along above-below direction vibration, so in the suspension 7, same movement and/or motion when producing with dried cloth weight detecting work in each one.Therefore, at this moment, control device 5 improves the viscosity of magnetic viscosity fluid 52 also to two coils 36 up and down, 39 energisings of damper 23, and appropriateness increases the damping force of damper 23, suppresses the vibration of tank 6.
When Fig. 7 has represented this cleaning with representing and two coils 36 up and down of the damper 23 when when work of rinsing then and dry work, 39 electrical current value.This electrical current value is to be worth accordingly with the washing weight that detects.That is, if the grade of the washing weight that detects " many ", then control device 5 is made as 0.3 (A) with two coils 36,39 electrical current value.If the washing weight that detects " in " grade, then control device 5 is made as 0.4 (A) with two coils 36,39 electrical current value.If the grade that the washing weight that detects " lacks ", then control device 5 is made as 0.5 (A) with two coils 36,39 electrical current value.That is, the washing weight that detects is fewer, and control device 5 more increases two coils 36,39 electrical current value.The damping force of damper 23 and two coils 36,39 electrical current value are proportional.In essence, the washing weight that detects is fewer, and control device 5 more increases the damping force of damper 23.
When Fig. 8 represents this cleaning and the relation of the damping force of the washing weight that detects when when work of rinsing then and dry work and damper 23.Control device 5 is according to what of the washing weight that detects, the damping force that makes damper 23 in this occasion in fact by this linear change shown in Figure 8.Thereby, can improve the response accuracy of the variation of damping force.
When cleaning the stroke end, control device 5 carries out drainage works.In this drainage works, control device 5 stops (outage) to two coils 36 up and down of damper 23,39 energising.Therefore, at this moment, the viscosity of magnetic viscosity fluid 52 can not improved by magnetic force.Thereby the damping force of damper 23 recovers the size by the natural viscosity acquisition of magnetic viscosity fluid 52.
Then the work in the dehydration stroke (this occasion is middle dehydration stroke) in detail as shown in Figure 1.In addition, the dehydration work in this dehydration stroke is to carry out with the corresponding time span of the washing weight that detects.
During this dehydration work, also follow the rotation of cylinder 10, tank 6 is mainly along above-below direction vibration (namely vibrating take above-below direction as main body).This occasion, the rotary speed of cylinder 10 are high during than cleaning, large movement and/or motion when therefore producing than cleaning in each one of suspension 7.Therefore, this dehydration is during work, when two coils 36 up and down of 5 pairs of dampers 23 of control device, 39 energising, and large current value energising with than cleaning the time.Thereby control device 5 improves the viscosity of magnetic viscosity fluid 52, increases the damping force of damper 23, suppresses the vibration of tank 6.
Fig. 9 has represented two coils 36 up and down of the damper 23 should dehydration work time the, 39 electrical current value with representing.The electrical current value of this occasion also is to be worth accordingly with the washing weight that detects.That is, if the grade of the washing weight that detects " many ", then control device 5 is made as 0.5 (A) with two coils 36,39 electrical current value.If the washing weight that detects " in " grade, then control device 5 is made as 0.8 (A) with two coils 36,39 electrical current value.If the grade that the washing weight that detects " lacks ", then control device 5 is made as 1.0 (A) with two coils 36,39 electrical current value.That is, this occasion too, control device 5 more increases two coils 36,39 electrical current value when the washing weight that detects is fewer, when the washing weight that detects is fewer, more increase the damping force of damper 23.
In addition, at this moment, control device 5 also according to the washing weight that detects what, makes the damping force reality of damper 23 by linear change shown in Figure 8.Thereby, improve the response accuracy of the variation of damping force.
Thereby, the initial stage of this dehydration stroke is (when the dehydration stroke starts, the rotary speed of cylinder 10 for example reaches 400 (rpm) before), two coils 36,39 up and down of damper 23 are carried out energising with the above-mentioned corresponding current value of washing weight that detects.In addition, Fig. 1 has represented with the corresponding current value of the washing weight that detects to be an example of the "on" position of 1 (A).Thereby, the damping force of the damper 23 of (rotation of cylinder 10 for example reach 400 (rpm) before) when the dehydration stroke that increase occurs in the resonance of tank 6 starts, avoid the generation of the resonance (resonance) of tank 6, improve the speed-raising performance of the rotation of cylinder 10.
In addition, at this moment, as mentioned above, control device 5 makes the rotary speed of cylinder 10 rise step by step at the uneven little states of rotation of holding more reliably cylinder 10 at different levels simultaneously.
In addition, in that the rotation of cylinder 10 is uneven when detecting, two coils 36,39 up and down of 5 pairs of dampers 23 of control device pass to the electric current of the corresponding current value of the washing weight that detects (being 1 (A) in the example) and remain unchanged.Thereby control device 5 makes the damping force of damper 23 large and certain.
In addition, the rotary actuation that control device 5 stops cylinder 10 subsequently makes rotary speed drop at 0 o'clock, namely, during the speed territory of the resonance of the rotary speed of cylinder 10 by tank 6 occurring, two coils 36,39 up and down of damper 23 are passed to electric current with the corresponding current value of the washing weight that detects (being 1 (A) in the example) again.Thereby control device 5 increases the damping force of damper 23 shown in Fig. 1 " damping force: large ", avoid the generation of the resonance of tank 6.
Then, control device 5 carries out the rinsing stroke.In this rinsing stroke, control device 5 also detects the weight detecting work of the washing weight of cylinder 10 interior existence at first.At this moment, the washings of cylinder 10 interior existence is the state behind cleaning stroke and the dehydration stroke, therefore is wet cloth.Thereby this weight detecting work is wet cloth weight detecting work.
Wet cloth weight detecting work is carried out identical content with the work of aforesaid dried cloth weight detecting.When the cloth weight detecting function that should wet carries out the detection of washing weight, control device 5 also (for example passes to the identical current value of the dried cloth weight detecting work carried out with dried cloth weight detecting function to two coils 36,39 up and down of damper 23,1 (A)) electric current, and continue this "on" position.
Then, control device 5 is undertaken to the water supply work of tank 6 interior water supply by feed water valve 58 is opened, until reach and the corresponding water level of the above-mentioned washing weight that detects (wet cloth weight).Then, control device 5 mainly carries out the rinsing work of " knocking rinsing " with the corresponding time span of the above-mentioned washing weight that detects (wet cloth weight) to washings by cylinder 10 is alternately rotated with the just contrary both direction of low speed.In this rinsing stroke, two coils 36 up and down of 5 pairs of dampers 23 of control device, 39 energising are carried out equally with the cleaning stroke.But, two coils 36 of this moment, 39 energising according to the corresponding current value of testing result of above-mentioned wet cloth weight detecting work, undertaken by Fig. 7 and content shown in Figure 1.Then, control device 5 is undertaken from the drainage works of tank 6 internal drainages by draining valve 15 is opened.In this drainage works, control device 5 stops two coils 36 up and down of damper 23,39 energising.
Then the work in the dehydration stroke (final dewatering stroke) and above-mentioned dehydration stroke (middle dehydration stroke) are same.But, two coils 36 of this moment, 39 energising according to the corresponding current value of testing result of above-mentioned wet cloth weight detecting work, undertaken by Fig. 9 and content shown in Figure 1.
Then, control device 5 carries out dry trip.In this dry trip, control device 5 also carries out weight detecting work (especially wet cloth weight detecting work) at first.In the time of should wetting the work of cloth weight detecting, the electric current of control device 5 identical current value (for example, 1 (A)) when also passing to dried cloth weight detecting work to two coils 36,39 about the damper 23, and continue this "on" position.
Then, control device 5 with the corresponding time span of the washing weight that detects (wet cloth weight), by making cylinder 10 rotations and drying unit 17 being worked, make the drying work of washings drying.At this moment, control device 5 according to the corresponding current value of testing result of above-mentioned wet cloth weight detecting work, undertaken two coils 36 up and down of damper 23,39 energising by Fig. 7 and content shown in Figure 1.
According to the rinsing maching of present embodiment described above, support the suspension 7 of the tank 6 of the cylinder 10 that is built-in with rotary actuation in the inner elastomeric of outer container 1, have the damper 23 of the vibration attenuation that makes tank 6.This damper 23 is dampers that damping force is changed.The testing result of the washing weight detecting unit of the washing weight that exists according to the inside of detecting cylinder 10, the washing weight that detects is fewer, makes the damping force of damper 23 larger.
Under the few situation of the washing weight that the inside of cylinder 10 exists, during cylinder 10 rotation, washings is difficult to be diffused into equably by centrifugal force the interior perimembranous of cylinder 10.Therefore, produce easily the off-centre of washings, produce easily imbalance, produce easily the large vibration of amplitude.In addition, on the contrary under the many situation of the amount of the washings that the inside of cylinder 10 exists, washings is diffused into the interior perimembranous of cylinder 10 easily equably by centrifugal force.Therefore, be difficult to produce the off-centre of washings, be difficult to produce imbalance, be difficult to produce the large vibration of amplitude.
According to the rinsing maching of present embodiment, the washing weight that detects is fewer, makes the damping force of damper 23 larger.By the damping force of such increase damper 23, can establishment be delivered to the vibration of tank 6 from cylinder 10.Thereby, can according to the washing weight that detects, when reducing vibration respectively, carry out later cleaning, dehydration work, rinsing work, dehydration work and dry work.Therefore, the user can use rinsing maching easily.
And according to the rinsing maching of present embodiment, the washings that control device 5 exists in the inside of cylinder 10 carries out the testing of the washing weight of washing weight detecting unit execution when being dried cloth.Washings is that dried cloth refers to the state of this washings before washing.Thereby, according to the rinsing maching of present embodiment, can carry out the weight detecting of washings the initial stage before the washings washing.Thereby, also can carry out from the zero hour of washing running with the control of the damping force of the corresponding damper 23 of the weight detecting result of this washings.Therefore, can obtain fast above-mentioned action effect.
And according to the rinsing maching of present embodiment, the washings that control device 5 also exists in the inside of cylinder 10 carries out the testing of the washing weight that the washing weight detecting unit carries out during for wet cloth.The water imbibition of washings is different because of cloth matter.Therefore, the washings that the high washings of water imbibition and water imbibition are low is compared, and the weight of wet cloth is large.Unbalanced load when the washings that therefore, water imbibition is high becomes cylinder 10 rotation easily.According to the rinsing maching of present embodiment, the washings that control device 5 also exists in the inside of cylinder 10 carries out the testing of washing weight when being wet cloth.Therefore, more high accuracy detects water imbibition because of the weight of the different washings of cloth matter.Thereby according to the testing result of washing weight and the subsequently control of the damping force of (after the weight detecting of washings) damper 23 of carrying out also can high accuracy be carried out, and obtains more reliably above-mentioned action effect.
The detection (detection of the washing weight of wet cloth) of the washing weight when in addition, the washings that exists of the inside of cylinder 10 is for wet cloth is carrying out at the rinsing stroke at first only also.That is, also carrying out at first at dry trip not of the detection of the washing weight of wet cloth.
