Abstract
The invention provides a washing machine, wherein the conduction detection of a damper is performed without hindering the attenuation force control of the damper. Meanwhile, the conduction detection of the damper is maintained to be constant regardless of the environment temperature. The suspension of an elastic support rotating groove is equipped with a damper for attenuating the vibration of a basin. The damp adopts a functional fluid and the viscosity of the functional fluid is changeable along with the applied power implemented by the energization of a coil. At a timing when the attenuation force of the damper is not changed, the conduction detection of the damper is performed, which will not hinder the attenuation force control of the damper. The energization of the coil is executed before the dehydration stroke (washing stroke), so that the viscosity of a magnetic viscous fluid and the hardness of a sealing member for preventing the leakage of the magnetic viscous fluid during the dehydration stroke at a low temperature are reduced. Therefore, the frictional force for shafts becomes moderate.

The divisional application that the application is the applying date is on March 24th, 2011, application number is 201110075183.X, denomination of invention is the application of rinsing maching.
Technical field
The present invention relates to the rinsing maching being applied in the damper of the vibration absorbing the tank drum-type of using function fluid or the longitudinal type rinsing maching such as automatically.
Background technology
As the first background technology, all the time, in various rinsing maching, wherein also comprise drum-type washing machine, tank is positioned at the inside of outer container, and the cylinder as swivelling chute is positioned at the inside of this tank, and this cylinder is by the motor rotary actuation outside tank.
In addition, tank is arranged by suspension flexibility on the base plate of outer container with supporting, and has make the vibration with cylinder and the damper of the vibration attenuation of tank that produces at this suspension.
With regard to this damper, usually use the type that damping force is constant, but also consider the type that use damping force is variable in recent years, and consider that using function fluid is as working fluid.
Called function fluid, it is the fluid that the physical quantity by controlling to apply from outside makes the character function ground of rheology (rheology) aspect of viscosity etc. change, comprise magnetic viscous fluid (the MR fluid of the fluid making viscosity B coefficent as the applying due to electric energy, MagnetorheologicalFluid, magneto-rheological fluid) and electric viscous fluid (ER fluid, Electrorheological Fluid, ERF).
Wherein, magnetic viscous fluid, it is the fluid of the ferromagnetism particulate being such as dispersed with iron, carbonyl (carbonyl) iron etc. in oil, if be applied in magnetic field, then catenulate bunch of ferromagnetism particulate shape (cluster), viscosity rises thus, if be applied in electric field, then the viscosity of electric viscous fluid can rise (reference example is as patent document 1,2).
In addition, as the second background technology, all the time, in drum-type washing machine, the base plate of outer container supports the suspension of tank, has and make to retract washings in the inside of tank and the damper of the vibration of swivelling chute (hereinafter referred to cylinder) rotated and even the vibration attenuation of tank.With regard to this damper, the known type (reference example is as patent document 3,4) to the magnetic viscous fluid (MR fluid) that working fluid uses viscosity to change according to the intensity in magnetic field.
Here, Figure 19 is the figure of the example representing this damper, as main element, has cylinder body 201 and axle 202.Wherein, cylinder body 201 is installed on tank (omitting diagram) by the attaching parts 203 being arranged at upper end, and axle 202 is installed on the installing plate (omitting diagram) set by the base plate of outer container by the connecting portion 202a of bottom.
Cylinder body 201, specifically comprises the two layered cylinder with urceolus 201a and inner core 201b, these urceolus 201a and inner core 201b, and its upper end is closed by urceolus end cap 204 and inner core end cap 205, and bottom is closed by urceolus sleeve 206 and inner core sleeve 207.
In the inner core 201b of cylinder body 201, be filled with magnetic viscous fluid 208.This magnetic viscous fluid 208 is the fluids of the ferromagnetism particulate being such as dispersed with iron, carbonyl iron etc. in oil, if be applied in magnetic field, then ferromagnetism particulate meeting catenulate bunch of shape, apparent viscosity rises thus.
Also with piston valve 209 in the inner core 201b of cylinder body 201.This piston valve 209 is components of short cylinder shape, is arranged at the upper end of described axle 202, and the outer peripheral face being configured to piston valve 209 relatively (axis) can reciprocatingly slide up and down at the inner peripheral surface of inner core 201b.
In addition, be formed with axially through multiple throttle orifices (orifice) 210 at the outer circumferential side of this piston valve 209, and be equipped with the coil 211 for generation of above-mentioned magnetic field.
For the lead-in wire 212 be energized to coil 211, be connected to outside drive circuit (omitting diagram) by the central part at axle 2 with the hole 213 formed by axial through mode.In addition, the hole 213 of axle 202 is closed by seal 214 closely in the upper end of axle 202.
The ratio attachment of axle 202 is fixed with the upper end part on the lower of above-mentioned piston valve 209, and the described inner core sleeve 207 of through cylinder body 201, urceolus sleeve 206 and seal 215, be projected into the below outside cylinder body 201, constitute damper 216 like this.
In addition, in the bottom of axle 202, attachment is fixed with spring fastening 217, and disc spring 218, elastically between this spring fastening 217 and described urceolus sleeve 206, constitutes the suspension 219 of resiliency supported tank like this.
In above-mentioned suspension 219, if tank vibrates along the vertical direction, then the cylinder body 201 of damper 216 also moves back and forth down along with the flexible of disc spring 218 integratedly in the axial direction with tank.
Now, owing to relatively moving back and forth up and down in the magnetic viscous fluid 208 of piston valve 209 in cylinder body 201, therefore magnetic viscous fluid 208 passes through in the throttle orifice 210 of piston valve 209, due to the viscosity of magnetic viscous fluid 208 now, produce damping force at suspension 219, the amplitude of tank is decayed.
The damping force D of generation described above, is generally represented by (1) formula below.
Damping force D=entrance loss+friction loss+dynamic pressure resistance (1)
In addition, so-called entrance loss refers to the pressure loss produced when magnetic viscous fluid 208 flows into the throttle orifice 210 of piston valve 209, friction loss refer to by magnetic viscous fluid 208 by throttle orifice 210 time the pressure loss that produces of pipe friction, dynamic pressure resistance refers to and does not carry out by the dynamic pressure of magnetic viscous fluid 208 pressure loss that pressure recover produces at piston valve 209 back side.
Here, if by being energized to coil 211 and applying magnetic field to magnetic viscous fluid 208, then the apparent viscosity of magnetic viscous fluid 208 rises.Thus, friction loss when magnetic viscous fluid 208 passes through in throttle orifice 210 increases, and therefore damping force D becomes large, can reduce the vibration of tank.

Drum-type described in the first above-mentioned background technology and longitudinal type automatically wait rinsing maching, and generally in rinsing maching, when dehydrating stroke, swivelling chute (cylinder) is understood and be vibrated due to the lateral deviation of washings sometimes, and accompany with it, tank also can vibrate.Now, if damping force tank being carried out to the damper of the suspension of resiliency supported is large, then the vibration of tank can be delivered to outer container via damper.
In addition, the damper of using function fluid, damping force can be changed by the change of the viscosity of functional fluid, thus, until reach the rotary speed of the resonance of tank when occurring that dehydrating stroke starts, increase damping force, improve by avoiding the acceleration making dehydration rotate of the resonance of tank, when dehydrating stroke after this stable (High Rotation Speed), reduce damping force, the vibration passing of tank can be avoided to outer container, and then this vibration passing can be avoided to the ground in room arranging rinsing maching.

On the other hand, in the damper 216 of the above-mentioned formation described in the second background technology, damping force D can be adjusted to the energising of coil 211, thus, until reach the rotary speed of the resonance of tank when occurring that dehydrating stroke starts by increase and decrease, increase damping force D, avoid the generation of the resonance of tank, when the dehydrating stroke is after this stablized, reduce damping force D, the vibration passing of tank can be avoided to outer container, and then this vibration passing can be avoided to the ground in room being provided with rinsing maching.
But in the environment for use of rinsing maching, temperature is different because of season, region, moment etc., and at temperature different like this, the viscosity B coefficent of magnetic viscous fluid 8, the hardness of this outside seal 15 also changes.Especially when low temperature, the viscosity of magnetic viscous fluid 8 increases, and the damping force D of damper 16 increases.Seal 15 hardness when low temperature also increases, and the frictional force of the seal 15 to crimped axle 2 also increases thus, so the damping force D of damper 16 increases.
Namely, in the existing technology described in the second background technology, the damping force D of damper 16 changes because of the temperature of the environment for use of rinsing maching, especially when low temperature, its damping force D increases, and may occur unfavorable condition that can not obtain stable fade performance etc., that the control of the damping force of damper is brought to obstruction.

And, also from the energising testing circuit 57 detected the energising of two coils 36,39 up and down each damper 21 of suspension 7a, 7b, energising detection signal is inputted to it.
Control device 5, based on the rotation detection signal from turn-sensitive device 56, execution is with the revolution of motor 8 and even the revolution of cylinder 10 divided by the computing detecting required time, and thus, the rotary speed testing agency also as the rotary speed detecting cylinder 10 plays a role.
And, control device 5, based on described various input and the prior control program stored, supply drive control signal to drive circuit 59, this drive circuit 59 drive the feed water valve 58 in order to arrange supplying water in tank 6, motor 8, draining valve 15, drive thermal source (heater) 20a (figure with reference to identical) of the heater 20 in the motor 19b (figure with reference to identical) of the wind feeding blades 19a of the pressure fan 19 in drying unit 17 (with reference to Fig. 2), this drying unit 17.
And, supply electric current via two coils 36,39 up and down in each damper 21 of current supply circuit 60 couples of suspensions 7a, 7b.
Fig. 5 represents the current control circuit 61 comprising energising testing circuit 57 and current supply circuit 60, for this current control circuit 61, two coils 36,39 up and down in each damper 21 of suspension 7a, 7b are connected in series respectively, these upper and lower two coils 36,39 are also connected in parallel in suspension 7a, 7b, are connected to current control circuit 61 via connector 62.
So, in current control circuit 61, by inputting High signal from control device 5 pairs of transistors 63, making transistor 63 conducting, accepting this Continuity signal and making the base stage of transistor 64 become Low, making transistor 64 conducting.
So the one-sided of resistance 65 becomes 15V, acted on the grid of FET67 by the voltage after resistance 65 and resistance 66 dividing potential drop, FET67 conducting.
If FET67 conducting, then apply the voltage of 36V to two coils 36,39 up and down in each damper 21 of suspension 7a, 7b respectively, electric current is passed to GND (greatly) via FET67 and current sense resistor 68.
Now, in current sense resistor 68, flow through the electric current of the value corresponding with the resistance value of current sense resistor 68 to each resistance value of two coils 36,39 up and down in each damper 21 of suspension 7a, 7b, reduce so there is the voltage corresponding to this current value at current sense resistor 68.
This voltage, by the low pass filter be made up of resistance 69 and capacitor 70, is read in by the A/D terminal of control device 5, according to resistance value and this voltage value, detects that two coils 36,39 up and down in each damper 21 of suspension 7a, 7b are normally energized.
Such current control circuit 61 comprises: as detecting the energising testing circuit 57 that could play a role to the energising testing agency of each upper and lower two coils 36,39 energisings.
Carry out the energising to each upper and lower two coils 36,39 when above-mentioned energising detects, performed by the input carried out continuously from control device 5 pairs of transistors 63, but when carrying out duty control to the input from this control device 5 pairs of transistors 63, in each upper and lower two coils 36,39, flow through the electric current of the mean value corresponding with its dutycycle.
By carrying out duty control to the input from control device 5 pairs of transistors 63 like this, the control of the electrical current to each upper and lower two coils 36,39 can be performed.
Like this, current control circuit 61, comprises the current supply circuit 60 played a role as the administration of power supply supplying electric current to each upper and lower two coils 36,39.And now, in current sense resistor 68, the current value of flowing also changes correspondingly, so carry out the mean value process of electrical current by control device 5, also can perform the detection of turn on angle.
Next, the effect of the rinsing maching of above-mentioned formation is described.In general, there is in the operation stroke of drum-type washing machine " washing (cleaning) stroke ", " rinsing (comprising dehydration) stroke " and " dry trip " etc.
Before the operation starting rinsing maching, if power supply connects (ON), then as shown in Figure 1, the energising being performed two coils 36,39 up and down in each damper 21 of suspension 7a, 7b by energising testing circuit 57 detects.
Step S1 ~ the S4 of Fig. 6, represents each step now, after power supply connects (step S1), performs energising and detects (step S2), its result, the judgement (step S3) performing whether turn on angle is 0A, namely whether be energized.
If its result is judged as that turn on angle is 0A, be not namely energized ("Yes" of step S3), then stop the energising to each upper and lower two coils 36,39, and other operation also stops, and carry out mistake display (step S4).
If be judged as that turn on angle is not 0A, is namely energized ("No" of step S3) in step s3, then start operation based on what run, enter " washing " stroke, carry out the energising (step S5) to each upper and lower two coils 36,39.The energising to each upper and lower two coils 36,39 now, performs via current supply circuit 60, also performs the detection of turn on angle when this energising.
In addition, now, the washings amount testing of the amount detecting the washings (dry) retractd in cylinder 10 is also performed.This washings amount testing, rotate according to making cylinder 10 until predetermined rotary speed, reach the predetermined rotary speed required time and stop the driving of cylinder 10 to make cylinder 10 inertial rotation, the thus rotary speed of cylinder 10 be reduced to predetermined rotary speed afterwards till required time, detected the amount of washings by the rotary load of motor 8.
When this washings amount testing, with the rotation of cylinder 10, tank 6 mainly vibrates in the vertical direction.Corresponding to the up-down vibration of this tank 6, in suspension 7a, 7b, be installed on the axle 23 of tank 6, while make disc spring 53 stretch, the through drag ring in limit 31, upper bearing (metal) 32, seal 33, upper magnet yoke 34, upper bobbin 37, middle yoke 38, lower lower 40, lower yoke 41, seal 43 and lower bearing 44, move back and forth in the vertical direction in the inside of cylinder body 23.
When the through so above-mentioned each parts of axle 23 move back and forth in the vertical direction, axle 23 and upper bobbin 37 and lower lower 40 each between and near them i.e. axle 23 and upper magnet yoke 34, middle yoke 38 and lower yoke 41 each between the magnetic viscous fluid 51 of filling, utilize the frictional resistance produced due to its viscosity to apply damping force to suspension 7a, 7b, the amplitude of tank 6 is decayed.
So when this washings amount testing, two coils 36,39 up and down via current supply circuit 60 pairs of dampers 21 are energized, and therefore, produce magnetic field, apply magnetic field to magnetic viscous fluid 51 by coil 36,39, and the viscosity of magnetic viscous fluid 51 raises.
Specifically, owing to being energized to coil 36,39, therefore produce the magnetic circuit of yoke 38-magnetic viscous fluid 51-axle 23 in the middle of axle 23-magnetic viscous fluid 51-upper magnet yoke 34-bracket 35-cylinder body 22-, and produce the magnetic circuit of yoke 38-cylinder body 22-lower yoke 41-magnetic viscous fluid 51-axle 23 in the middle of axle 23-magnetic viscous fluid 51-, the viscosity of the magnetic viscous fluid 51 of the position that each magnetic flux passes through raises.
The viscosity of each magnetic viscous fluid 51 between the axle 23 that especially magnetic density is high and upper magnet yoke 34, between middle yoke 38 and axle 23 and between lower yoke 41 and axle 23 raises, and frictional resistance increases.
Like this, frictional resistance when cylinder body 22 vibrates in the vertical direction with each parts, especially upper and lower two coils 36,39 and upper magnet yoke 34, middle yoke 38 and lower yoke 41 increases, thus damping force is increased.
Thereby, it is possible to suppress tank 6 to vibrate, so also the detection of washings amount correctly can be performed.
In addition, now, being more difficult to make the vibration of tank 6 occur, making to flow through in each upper and lower two coils 36,39 electric current of slightly many such as 1A, the damping force of damper 21 is increased.
And, if the testing of washings amount terminates, then stop the driving of cylinder 10, also stop the energising (end of step S5) to each upper and lower two coils 36,39.
Afterwards, perform the display of the operation required time corresponding with the testing result of the amount of washings and the display of necessary detergent amount, wait for that the scheduled time is to wait for that washing agent drops into (step S6) in this condition.
During wait washing agent drops into, whether be whether 0rpm, i.e. cylinder 10 stop the rotation and judge (step S7) to the rotary speed of cylinder 10.
If judge that cylinder 10 is 0rpm, namely stopped ("Yes" of step S7), then performed energising detection (step S8) of each upper and lower two coils 36,39 by energising testing circuit 57.
And, on its basis, whether whether the turn on angle of each upper and lower two coils 36,39 be 0A, be namely energized and judge (step S9), if judge it is 0A, be not namely energized ("Yes" of step S9), then stop the energising to each upper and lower two coils 36,39, and also stop other operation, then carry out mistake display (step S10).
In step s 9, if be judged as that turn on angle is not 0A, be namely energized ("No"), then then making feed water valve 58 open, performing the water supply work (step S11) to supplying water till the water level corresponding with the testing result of washings amount in tank 6.
When this water supply work, via current supply circuit 60, each upper and lower two coils 36,39 are not energized, also do not carry out the detection (with reference to Fig. 1) of the energising performed by energising testing circuit 57.
After water supply work, perform the washing work (step S12) cylinder 10 alternately being rotated in forward and reverse direction with low speed, mainly carries out impacting washing to washings.Step S5 above ~ S11 also as shown in Figure 1.
When the work of washing, in midway, (being 2 times in illustrative example) improves the rotary speed of cylinder 10 several times, thus makes washings soak into washings better, improves clean result.
Now, two coils 36,39 up and down via current supply circuit 60 pairs of dampers 21 are energized, and also perform the detection of turn on angle when this is respectively energized.
Thus, as described above, produce magnetic field, apply magnetic field to magnetic viscous fluid 51 by coil 36,39, the viscosity of magnetic viscous fluid 51 improves, so the damping force of damper 21 increases, can suppress the vibration because improving the tank 6 that rotary speed causes.
But the rotary speed of cylinder 10 now, than low during dewatering work in " rinsing " described later stroke, flow through the electric current of slightly large such as 0.5A, makes the damping force of damper 21 moderately increase in each upper and lower two coils 36,39.
In addition, in addition, do not carry out via the energising (do not make the damping force of damper 21 increase) of current supply circuit 60 to each upper and lower two coils 36,39, even if but under these circumstances, damper 21 also has the damping force obtained because of the natural viscosity of magnetic viscous fluid 51, and, also can obtain the damping force because the friction between drag ring 31 and axle 23 produces, so tank 6 can not become abnormal vibrational state.
After the work of " washing " stroke, carry out " rinsing " stroke, make draining valve 15 open, perform the drainage works from tank 6 internal drainage.
In this drainage works, do not carry out via the energising of current supply circuit 60 to each upper and lower two coils 36,39, and the energising performing each upper and lower two coils 36,39 undertaken by energising testing circuit 57 detects.
Whether its result, as described above, judge being energized, if be judged as not energising, then stop the energising to each upper and lower two coils 36,39, and also stop other operation, and carry out mistake and show.
In dehydration (middle dehydration) work afterwards, cylinder 10 is rotated, its rotary speed is improved gradually, by centrifugal force the water residued in washings thrown away and discharge.
In this process, occur that in the rotating range (being the stage of such as 0 ~ 400rpm usually with the rotating speed indicating of cylinder 10) of resonance and the process that speed is lowered gradually after the rotation of cylinder 10 reaches maximum speed, the rotating range (being the speed stage of such as 400 ~ 0rpm with the rotating speed indicating of cylinder 10) of resonance appears in tank 6 at tank 6, two coils 36,39 up and down respectively via current supply circuit 60 pairs of dampers 21 are energized.Also the detection of turn on angle is performed when this is respectively energized.
Thus, produce magnetic field, apply magnetic field to magnetic viscous fluid 51 by upper and lower two coils 36,39, the viscosity of magnetic viscous fluid 51 improves, so the damping force of damper 21 increases.
In addition, under these circumstances, the rotary speed of cylinder 10 than high during described washing work, so apply than action large during washing work and/or effect from each several part of tank 6 couples of suspensions 7a, 7b.
Therefore, now, make the value of the electric current flowed in two coils 36,39 up and down of damper 21 via current supply circuit 60 larger than current value during washing work, such as, with the electric current of the same 1A that the flows during testing of washings amount, make the damping force of damper 21 become large, suppress the vibration of tank 6.
When this dewatering work, beyond above-mentioned rotating range, via current supply circuit 60, (not making the damping force of damper 21 increase) is not energized to each upper and lower two coils 36,39, even if but under these circumstances, damper 21 has the damping force obtained because of the natural viscosity of magnetic viscous fluid 51, and, also obtain the damping force produced by the friction between drag ring 31 and axle 23, so tank 6 there will not be abnormal vibrational state.
Next, the water supply work in " rinsing " stroke is performed.This water supply work, identical with the content of water supply work before during described washing work, therefore, under these circumstances, do not carry out via the energising of current supply circuit 60 to each upper and lower two coils 36,39, the energising also do not carried out performed by current supply circuit 60 detects (with reference to Fig. 1).
Afterwards, rinsing work is performed.This rinsing works, identical with content during described washing work, therefore, under these circumstances, in order to make washings soak into washings better, improves the rotary speed of cylinder 10.
The rotary speed of this cylinder 10 improves carries out several times (being 2 times in illustrative example) in rinsing work midway, is now energized to upper and lower two coils 36,39 via current supply circuit 60, and also performs the detection of turn on angle when being energized.
Thus, produce magnetic field, apply magnetic field to magnetic viscous fluid 51 by upper and lower two coils 36,39, the viscosity of magnetic viscous fluid 51 improves, so the damping force of damper 21 increases, can suppress the vibration of tank 6.
Afterwards, drainage works is performed.This drainage works is identical with the content of the drainage works after described washing work, be not therefore energized to each upper and lower two coils 36,39 via current supply circuit 60, and the energising performing each upper and lower two coils 36,39 undertaken by energising testing circuit 57 detects.
Whether its result, as described above, judge being energized, if be judged as not energising, then stop the energising to each upper and lower two coils 36,39, and also stop other operation, and carry out mistake and show.
Afterwards, dehydration (final dewatering) work in " rinsing " stroke is performed.This dewatering work is identical with the content that above-mentioned dehydration (dewatering in centre) works.
Namely, there is the rotating range of resonance at tank 6 in the process making the rotary speed of cylinder 10 improve gradually, there is the rotating range of resonance equally at tank 6 in the process that after arriving maximum speed with the rotation of cylinder 10, speed lowers gradually, via current supply circuit 60, each upper and lower two coils 36,39 are carried out to the energising of slightly large such as 1A respectively, also perform the detection of turn on angle when this is respectively energized.
Thus, produce magnetic field by each upper and lower two coils 36,39, apply magnetic field to magnetic viscous fluid 51, the viscosity of magnetic viscous fluid 51 improves, so the damping force of damper 21 increases, suppresses the vibration of tank 6.
Afterwards, carry out " drying " stroke, perform washings (wet mass) and measure testing.This washings amount testing, identical with the content of the washings amount testing at above-mentioned " washing " stroke initial stage, therefore, via current supply circuit 60, each upper and lower two coils 36,39 are carried out to the energising of such as slightly large 1A, and also perform the detection of turn on angle when each energising.
By the energising to upper and lower two coils 36,39, the damping force of damper 21 is increased, so be difficult to vibrate at tank 6, and can correctly detect washings amount.
Afterwards, dry work is performed.This drying works, and by limit, cylinder 10 is rotated in forward and reverse direction with low speed, while make drying unit 17 play a role, the air in tank 6 is circulated by dehumidifier 18, pressure fan 19 and heater 20 successively, thus makes washings dry.
Now, the energising performing each upper and lower two coils 36,39 undertaken by energising testing circuit 57 off and on detects.Whether its result, as described above, judge being energized, if be judged as not energising, then stop the energising to each upper and lower two coils 36,39, and also stop other running, and carry out mistake and show.
In addition, the energising of each upper and lower two coils 36,39 in this drying work, that undertaken by energising testing circuit 57 detects, and carries out to use rinsing maching next time.
In above-mentioned formation shown by first embodiment of the first invention in such the present invention, the tank 6 being configured with the cylinder 10 be driven in rotation in inside is carried out to suspension 7a, 7b of resiliency supported in the inside of outer container 1, there is the damper 21 of the vibration of decay tank 6.
And damper 21, use and make the functional fluid of viscosity B coefficent change to make damping force because of the applying of the electric energy carried out that is energized, the timing beyond when the damping force change making damper 21, the energising implementing this damper 21 detects.
As mentioned above, damper 21 uses and makes the functional fluid of viscosity B coefficent to obtain necessary damping force due to the applying of electric energy, and damper 21 must reliably be energized for this reason.
But, under the situation that the lead-in wire disconnection etc. for being energized to damper 21 can not be energized to damper 21, can not expected effect be obtained.
In contrast, in formation of the present invention, the energising implementing damper 21 detects, so can grasp the situation that damper 21 could be energized, controls the damping force of damper 21.
And the energising that damper 21 is implemented in the timing beyond when the damping force change that must make damper 21 detects, and brings therefore can not to the control of the damping force of damper and hinders and can carry out this energising detection.
In addition, in especially above-mentioned formation, in the timing beyond when the damping force change making damper 21, before the operation of rinsing maching starts, the energising implementing damper 21 detects.
Thus, except above-mentioned effect, the situation could carrying out the energising of damper 21 can be grasped as soon as possible before operation starts, obstruction can not be brought to operation entirety.
In addition, in the above-described configuration, in the timing beyond when the damping force change making damper 21, when the rotation of cylinder 10 stops, the energising implementing damper 21 detects.
Thus, can avoid: the energising when cylinder 10 rotates in order to implement damper 21 detects and is energized to damper 21 thus makes the damping force of damper 21 change this situation, the damping force of the damper 21 when cylinder 10 rotates can be guaranteed rightly, also can suppress the vibration of tank 6 rightly.
And in the above-described configuration, the energising of damper 21 detects, in the timing beyond when the damping force change making damper 21, the time of the wait putting detergent after the detection implementing the washings amount in " washing " stroke, implement.
Thus, even if after operation starts, also the energising can implementing damper 21 when cylinder 10 stops the rotation detects, so as described above, can avoid: the energising when cylinder 10 rotates in order to implement damper 21 detects and is energized to damper 21 thus makes the damping force of damper 21 change this situation, the damping force of the damper 21 when cylinder 10 rotates can be guaranteed rightly, also can suppress the vibration of tank 6 rightly.
And, under these circumstances, by utilizing the time waiting for putting detergent, not needing after operation starts out of service in order to the energising carrying out damper 21 detects, the waste of running time can be eliminated.
In addition, in the above-described configuration, the energising of damper 21 detects, and in the timing beyond when the damping force change making damper 21, during draining before the dewatering work in " rinsing " stroke, implements.
Thus, even if after operation starts, also the energising can implementing damper 21 when cylinder 10 stops the rotation detects, so as described above, can avoid: the energising when cylinder 10 rotates in order to implement damper 21 detects and is energized to damper 21 thus makes the damping force of damper 21 change this situation, the damping force of the damper 21 when cylinder 10 rotates can be guaranteed rightly, also can suppress the vibration of tank 6 rightly.
And, under these circumstances, during by utilizing the draining before dewatering work, do not need run start after out of service in order to the energising carrying out damper 21 detects, the waste of running time can be eliminated.
Fig. 7 to Fig. 9 represents the second to the four embodiment of the first invention in the present invention, respectively the part same with the first embodiment of the first invention in the present invention is marked to same symbol and omits the description, being only described different parts.
(the second embodiment of the first invention in the present invention)
In the second embodiment shown in Fig. 7, the energising of damper 21 detects to be implemented between the rotating and reverse of cylinder 10.
In the work of the work of described " washing " stroke, the work of " rinsing " stroke and " drying " stroke, as mentioned above, make cylinder 10 in forward and reverse direction, replace rotation with low speed to carry out, namely as shown in the first half of Fig. 7, rotating and reverse of cylinder 10 is alternately performed.
This cylinder 10 alternately perform rotate and reverse time, as shown in the latter half of this figure, the energising implementing damper 21 between the rotating and reverse of this cylinder 10 detects.
Between the rotating and reverse of above-mentioned cylinder 10, in order to make cylinder 10 reverse, cylinder 10 is temporarily stopped.Therefore, under these circumstances, the energising also can implementing damper 21 when cylinder 10 stops the rotation detects.
Therefore, as described above, can avoid: the energising when cylinder 10 rotates in order to implement damper 21 detects and is energized to damper 21 thus makes the damping force of damper 21 change this situation, the damping force of the damper 21 when cylinder 10 rotates can be guaranteed rightly, also can suppress the vibration of tank 6 rightly.
And, under these circumstances, by respectively utilize " washing " work time, " rinsing " work time and " drying " work time respective cylinder 10 forward and reverse between time, do not need after operation starts out of service in order to the energising carrying out damper 21 detects, the waste of running time can be eliminated.
In addition, under these circumstances, the energising of damper 21 detects, respectively when " washing " work, in " rinsing " respective scheduled time when working and when " drying " works, enforcement is repeatedly.
By implementing repeatedly like this, the situation that damper 21 could be energized more accurately can be grasped.
The energising of damper 21 detects, and also can carry out when " washing " work, between the forward and reverse of the cylinder 10 of " rinsing " at least one when working and when " drying " works when working.
In addition, the energising of damper 21 in this case detects, the time beyond when each upper and lower two coils 36,39 by current supply circuit 60 pairs of dampers 21 are energized, at no power time, implement.
And, implement in the given time repeatedly about the energising of damper 21 is detected, perform when can detect in other above-mentioned energisings.
(the 3rd embodiment of the first invention in the present invention)
In the 3rd embodiment of the present invention shown in Fig. 8, in the energising implementing repeatedly damper 21 detects, when repeated detection is not energized to damper 21, be judged as that damper 21 can not be energized.
Specifically, be judged as in step S3, S9 in the control content shown in above-mentioned Fig. 6 that turn on angle is 0A ("Yes" respectively, not energising) time, whether such as 3 times so repeatedly judging (step S101, S103) are reached to the detection number of times that this turn on angle is 0A, if be judged as not reaching 3 times ("No"), then return the energising detection that step S2, S8 carry out damper 21.
On the other hand, when being judged as that in step S3, S9 turn on angle is not 0A ("No", be energized) time, whether energising detection number of times is reached and judges for 5 times (step S102, S104), if be judged as not reaching 5 such repeatedly ("No"), then return step S2, S8, the energising carrying out damper 21 detects.
And, between enforcement 5 energising detection periods, the detection number of times that turn on angle is 0A reach such as 3 times so repeatedly time (in step S101, S103 "Yes"), as being judged as the content that damper 21 can not be energized respectively, enter described step S4, S10, stop the energising to each upper and lower two coils 36,39 of damper 21, and also stop other operation, and carry out mistake display.
In addition, after implementing 5 energisings and detecting (in step S102, S104 "Yes"), step S5, S11 is entered respectively.
Like this, when repeatedly implementing not to be energized to damper 21 in repeated detection between the energising detection period of damper 21, be judged as that damper 21 can not be energized (step S4, S10), thus more reliably can hold the situation that damper 21 could be energized.
Especially can eliminate and judge because of the noise in the circuit shown in Fig. 5 the situation that damper 21 could be energized mistakenly.
(the 4th embodiment of the first invention in the present invention)
In the 4th embodiment of the present invention shown in Fig. 9, compared with the turn on angle of the damper 21 when changing with making the damping force of damper 21, the turn on angle of the damper 21 when the energising carrying out damper 21 is detected is less.
Under these circumstances, as shown in Fig. 9 (a), the turn on angle of the damper 21 (upper and lower two coils 36,39) when changing making the damping force of damper 21 is set to A, as shown in Fig. 9 (b), when the turn on angle of the damper 21 when the energising carrying out damper 21 being detected is set to B, be energized in the mode of turn on angle A > turn on angle B.
So, the energising that just can perform damper 21 by flowing through required fully little electric current detects, and can suppress less by power consumption.
In addition, under these circumstances, with represent during dewatering work make damper 21 damping force change time and with when " washing " work, " rinsing " work time and " drying " work time respective cylinder 10 forward and reverse between illustrate carry out damper 21 energising detection time, but in addition, when other already described damping force changes and when energising detects, turn on angle is set as above-mentioned turn on angle A > turn on angle B similarly.
In addition, as the rinsing maching of the first invention in the present invention, be not limited to drum-type, the vertical shape full-automatic washing machine with can being applied to longitudinal axis shape too with tank and swivelling chute is implemented.
And, also can be the rinsing maching without functions/drying.
In addition, in the above-described embodiment, how cause being energized for content detects to the energising performing damper 21 (upper and lower two coils 36,39) with the situation detected because of the lead-in wire such as disconnection of lead-in wire, but be not limited thereto, also can cause producing abnormal current with the short circuit etc. detected because of coil 36,39 for content performs.

And, control device 225, based on described various input, testing result and the prior control program stored, supply drive control signal to drive circuit 270, this drive circuit 270 drives in order to thermal source (heater) 240a of heater 240 in the feed water valve 269 of setting, motor 228, draining valve 235, the motor 239a driving the wind feeding blades of the pressure fan 239 in drying unit 237 (not having to illustrate), this drying unit 237 to supplying water in tank 226 and the coil 254 in the damper 241 of described suspension 227.
Then, the effect of the first embodiment of the second invention in the invention described above is described.
Based on guidance panel 224 operation, by control device 225, operation is started time, the situation of standard is, as shown in Figure 10, operation is performed according to the order of " washing (cleaning) stroke ", " dehydrating stroke ", " rinsing stroke " and " dry trip ".
Wherein, in " washing stroke ", omit detailed description, first, perform the weight detecting work of the amount detecting the washings retractd in cylinder 230, then, perform and make the open water supply work to supplying water in tank 226 till the water level corresponding to detecting washings amount of feed water valve 269.In addition, now, with the supply performing the washing agent be positioned in not shown detergent container of supplying water simultaneously.
After water supply work, cylinder 230 is rotated, frontier inspection surveys the material of the washings retractd in cylinder 230, and limit performs the washing work mainly carrying out impacting washing to washings.
When this washing work, along with the rotation of cylinder 230, tank 226 mainly vibrates in the vertical direction.Corresponding to the up-down vibration of this tank 226, in suspension 227, be installed on the cylinder body 242 of tank 226, along with upper magnet yoke 251 and bearing 253, bobbin 255 and coil 254, bracket 259 and lower yoke 256, seal 257 and bearing 258, while make disc spring 265 stretch, while vibrate in the vertical direction around axle 243.
When cylinder body 242 vibrates in the vertical direction with above-mentioned each parts like this, axle 243 between axle 243 and bobbin 255 and coil 254 and near it and the magnetic viscous fluid 263 of filling between upper magnet yoke 251 and between axle 243 and lower yoke 256, by the frictional resistance produced due to its viscosity, damping force is applied to suspension 227, the amplitude of tank 226 is decayed.
So, in this washing stroke, coil 254 is carried out to predetermined value, is now the energising of electric current of 0.SA.Coil 254 is energized, produces magnetic field, magnetic field is applied to magnetic viscous fluid 263, the viscosity of magnetic viscous fluid 263 is raised.
Specifically, owing to being energized to coil 254, therefore producing the magnetic circuit of axle 243-magnetic viscous fluid 263-upper magnet yoke 251-cylinder body 242-bracket 259-lower yoke 256-magnetic viscous fluid 263-axle 243, the viscosity of the magnetic viscous fluid 263 of the position that magnetic flux passes through raises.
The viscosity of each magnetic viscous fluid 263 between the axle 243 that especially magnetic density is high and upper magnet yoke 251 and between lower yoke 256 and axle 243 raises, and frictional resistance increases.
Like this, frictional resistance when cylinder body 242 vibrates in the vertical direction with described each parts, especially coil 254, upper magnet yoke 251 and lower yoke 256 increases, and causes damping force to increase.
In addition, meanwhile, because coil 254 generates heat, especially when low temperature, magnetic viscous fluid 263 is heated, and avoid its viscosity and become too high, the hardness of seal 257 also lowers, and the frictional force avoided for axle 202 becomes excessive.
Thus, how the temperature (especially low temperature) regardless of environment for use can make the damping force of damper 241 necessarily change, and can obtain stable fade performance.In addition, the damping force of damper 241 is now A.
After washing stroke terminates, draining valve 235 is made to open and perform the drainage works from tank 226 internal drainage.In this drainage works, stop the energising (power-off) to described coil 254.
Therefore, now, the viscosity of magnetic viscous fluid 263 can not raise because of magnetic force, and the damping force of damper 241 gets back to the size obtained by the natural viscosity of magnetic viscous fluid 263.
The damping force of damper 241 is now C, less than the damping force A of the damper 241 during described washing stroke (A > C).In addition, the damping force C of damper 241 now also can equal with the damping force A of the damper 241 during described washing stroke (A=C).
In " dehydration " stroke afterwards, cylinder 230 is rotated, its rotary speed is made to increase step by step, by centrifugal force, the water remained in washings thrown away and discharge, at its initial stage (during starting at dehydrating stroke, till the rotating speed of cylinder 230 reaches such as 400rpm from 0), described coil 254 is carried out to predetermined value, is now the energising of the electric current of the 1A larger than current value during described washing stroke.
If be energized to coil 254, then the viscosity of magnetic viscous fluid 263 raises as mentioned above, current value during the current value ratio washing stroke now flow through in coil 254 is large, so the magnetic force being applied to magnetic viscous fluid 263 is also large, therefore the viscosity of magnetic viscous fluid 263 is also high than viscosity during washing stroke, and the damping force of damper 241 becomes large.
The damping force of damper 241 is now B, than the damping force A large (B > A) of the damper 241 when the stroke beyond dehydrating stroke and described washing stroke.
Thus, increase the damping force of the damper 241 when the starting of dehydrating stroke of resonance appears in tank 226, avoid tank 226 to resonate, the acceleration improvement that cylinder 230 is rotated, smoothly to transition during ensuing dehydrating stroke stable.
When dehydrating stroke stable, continue the rotation maintaining cylinder 230 at high speed, now, the vibration of tank 226 is little, but still can occur, so need to avoid this vibration passing to outer container 221, and then will avoid the ground being delivered to the room being provided with scrubbing-and-drying unit.
Now, by stopping the energising (power-off) to described coil 254, the viscosity of magnetic viscous fluid 263 can not be raised because of magnetic force, and the damping force of damper 241 gets back to the size (C) obtained by the natural viscosity of magnetic viscous fluid 263.
Then, in the latter stage of dehydrating stroke, in the same manner as when the starting of described dehydrating stroke, tank 226 will resonate, so apply the electric current of the 1A larger than current value during described washing stroke in the same manner as coil 254 is in time starting.
Thus, the viscosity during ratio of viscosities washing stroke of magnetic viscous fluid 263 is high, and the damping force of damper 241 is increased to B, thus avoids tank 226 and resonate, and the performance improvement at the end of making dehydrating stroke, makes dehydrating stroke smoothly terminate.
In " rinsing " stroke afterwards, at first, make feed water valve 269 open and perform the water supply work of water supply till the water level that the detection washings amount with described is corresponding in tank 226, then, cylinder 230 is rotated, performs " rinsing " work mainly impacting rinsing washing materials.
In stroke beyond dehydrating stroke i.e. this rinsing stroke, perform the energising to coil 254 in the same manner as described washing stroke.
Afterwards, not diagram, follow-uply carry out final dehydrating stroke, dry trip, final dehydrating stroke also comprises and being energized to coil 254, perform in the same manner as described dehydrating stroke, in dry trip, limit makes cylinder 230 rotate limit drying unit 237 to be played a role and makes washings dry, performing the energising to coil 254 in the same manner as described washing stroke.
In first embodiment of the second invention in such the present invention, have the damper 241 of the vibration attenuation making the tank 226 retracing cylinder 230, this damper 241 has: cylinder body 242; Remain on the inside of this cylinder body 242 and produce the coil 254 in magnetic field by being energized; Can relatively reciprocatingly this coil 254 through by the axle 243 supported in the axial direction; Be filled in the magnetic viscous fluid 263 between this axle 243 and above-mentioned coil 254 and near it; Seal 257 with the leakage of this magnetic viscous fluid 263 of supression, namely carries out the energising to coil 254 from washing stroke from before dehydrating stroke.
The energising to coil 254 is carried out like this from before dehydrating stroke, thus the viscosity of magnetic viscous fluid 263 reduced in the dehydrating stroke especially when low temperature and the hardness of seal 257, the frictional force for axle 243 can be made to become appropriateness, so the damping force of damper 241 how can be made necessarily to change regardless of the temperature of environment for use, stable fade performance can be obtained.
And, in the above-described configuration, the pass of the damping force C of the damper 241 when the damping force B of the damper 241 during to make the starting of the damping force A of the damper 241 of the stroke beyond dehydrating stroke, dehydrating stroke and dehydrating stroke are stablized is the mode of B > A >=C, performs the energising to coil 254.
As mentioned above, at the initial stage of washing stroke, perform the weight detecting work of the amount detecting the washings retractd in cylinder 230, in washing stroke, perform the detection of the material of the washings retractd in cylinder 230.
These detect by detecting rotations of motor 228 of making cylinder 230 rotate and/or cogging performs, if so make the damping force of damper 241 increase and the extra-inhibitory vibration of tank 226, then detection can not be carried out accurately.
Therefore, damper 241 is by the vibration suppression of tank 226 to the MIN damping force (A) that there will not be the vibration of such problem, can not perform exceed necessary energising to coil 254 when washing stroke.
In contrast, when the starting of dehydrating stroke, as mentioned above, in order to avoid the acceleration that resonance improves cylinder 230 rotation occurs tank 226, need to make the damping force of damper 241 (B) large as far as possible.
On the contrary, when dehydrating stroke stable, the vibration of tank 226 is transmitted to outer container 221, transmit earthward and all become problem, so must reduce damping force (C).
Therefore, in stroke (especially at washing stroke) beyond dehydrating stroke, the electric current reducing to flow through in coil 254 makes the damping force A of damper 241 reduce, increasing the electric current flow through in coil 254 when the starting of dehydrating stroke makes the damping force B of damper 241 increase, and the electric current reducing when dehydrating stroke is stablized to flow through in coil 254 makes damping force C reduce (B > A >=C).
Thus, during the starting of the stroke beyond dehydrating stroke, dehydrating stroke and when dehydrating stroke stablizes, can respectively with most suitable damping force no problem run.
And, in the first embodiment of the second invention in the invention described above, go through from (washing stroke) before dehydrating stroke and stop changing to dehydrating stroke during coil 254 energising.
During changing from (washing stroke) before dehydrating stroke to dehydrating stroke, during being execution drainage works.When performing this drainage works, the water in tank 226 is discharged, and the gross weight of tank 226 diminishes, so the load that the disc spring 265 of suspension 227 is born diminishes.
Thus, disc spring 265 pushes away tank 226 from the cylinder body 242 of damper 241 makes it restore, but now, if coil 254 is energized, then the viscosity of magnetic viscous fluid 263 increases, frictional force for axle 243 becomes large, thus tank 226 from cylinder body 242 go up (restoring to dehydration initial stage posture) slack-off.
With regard to scrubbing-and-drying unit (rinsing maching) in recent years, expect to shorten and run required time, the time that can be used for drainage works also shortens, so the rise of above-mentioned tank 226 is slowly inappropriate.
Relative to this, be set as before dehydrating stroke (washing stroke) go through stop being energized to coil 254 during and to the above-mentioned formation that dehydrating stroke changes, by stopping the energising to this coil 254, the viscosity of magnetic viscous fluid 263 is reduced, the frictional force for axle 243 can be made to reduce, so tank 226 can be made very fast from the rise of cylinder body 242, the shortening of drainage works time can be contributed to and then all run the shortening of required time.
Then, Figure 14 to Figure 18 illustrates the second to the five embodiment of the second invention in the present invention, marks same symbol respectively, omits the description, be only described different parts the part same with the first embodiment of the second invention in the present invention.
(the second embodiment of the second invention in the present invention)
In second embodiment of the second invention in the present invention shown in Figure 14, detect the temperature of extraneous gas (extraneous air), determine current value or the length of conduction time of the energising to coil 254 carried out before dehydrating stroke according to its testing result.
Specifically, now, as the temperature testing organization of the temperature of detection extraneous gas, not shown, such as, bottom in outer container 201 is provided with temperature sensor.Before dehydrating stroke (during washing stroke), first detected the temperature (step S21) of extraneous gas by said temperature sensor, then judge its testing result (temperature of the extraneous gas detected) whether low than 5 DEG C (step S22).
In above-mentioned steps S22, if be judged as low ("Yes"), then the current value be energized to coil 254 is set as 1A, is maybe 10 minutes by the length setting of the time be energized to coil 254, performs the energising (step S23) to this coil 254.
In contrast, in step S22, if be judged as the temperature of extraneous gas low unlike 5 DEG C ("No"), then judge the testing result whether low than 30 DEG C (step S24) in above-mentioned steps S21.
In this step S24, if be judged as low ("Yes"), then the current value be energized to coil 254 is set as 0.5A, maybe the time span be energized to coil 254 is set as 5 minutes, perform the energising (step S25) to this coil 254.
In addition, in above-mentioned steps S24, if be judged as not low ("No"), then the energising (step S26) to coil 254 is not performed.
Like this, the control (determine current value or instead determine the length of conduction time) that coil 254 is energized is performed according to the temperature of the actual extraneous gas detected, thus can correspondingly adjust the damping force of damper 241 with the temperature of environment for use, meaningless (unnecessary) energising can not be carried out to coil 254, can run efficiently.
(the 3rd embodiment of the second invention in the present invention)
In 3rd embodiment of the second invention in the present invention shown in Figure 15, detect the current value flow through in coil when the energising from before dehydrating stroke, control according to the energising to coil 254 during its testing result execution dehydrating stroke.
Specifically, now, as the current value testing agency detecting the current value flow through in coil 254 when the energising from before dehydrating stroke, although not shown, but there is such as current sensor.
Before dehydrating stroke (during washing stroke), first the energising (step S111) to coil 254 is started, then current value (step S112) is detected by above-mentioned current sensor, afterwards, its testing result (detected current value) is judged whether than 50% little (step S113) of the predetermined current value flow through before this dehydrating stroke.
In above-mentioned steps S113, if be judged as little ("Yes"), then stopped being energized (step S114) to coil 254, return step S112.Relative to this, in step S113, if be judged as not little ("No"), then until stroke (dehydrating stroke, rinsing stroke, final dewatering stroke, dry trip) afterwards continues to perform the energising (step S115) to coil 254 with respective predetermined current value.
Then, afterwards, judge whether running time terminates (step S116), if be judged as not terminating ("No"), then return step S115, if be judged as terminating ("Yes"), then terminate the energising (step S117) to coil 254.
Control the energising to coil 254 according to the temperature of extraneous gas, thus according to the damping force of the temperature of environment for use adjustment damper 241, can not carry out meaningless energising, can run efficiently coil 254, these situations all with above-mentioned are identical.
Now, the temperature of environment for use also shows as the temperature of coil 254.In addition, the temperature of coil 254, also different because of the adjusting frequency etc. of damping force of damper 241, frequency of its adjustment is high, and the temperature of coil 254 also raises.
In contrast, the electric current flow through in coil 254, the different sizes because of the temperature of coil 254.That is, if the temperature of coil 254 is high, then the electric current flow through in coil 254 reduces, if the temperature of contrary coil 254 is low, then the ER effect flow through in coil 254 is large.
Therefore, detect the current value flow through in coil 254, thus the temperature of coil 254 and then the temperature of environment for use and/or frequency of utilization etc. can be judged, from this viewpoint, as in this embodiment, the current value flow through in coil 254 is detected when the energising from before dehydrating stroke, according to its testing result, energising to coil 254 during control dehydrating stroke, thus as described above, can corresponding to the damping force of the temperature adjustment damper 241 of environment for use.
In addition, also can corresponding to the damping force of the adjustment dampers 241 such as frequency of utilization, can not carry out meaningless energising to coil 254 also can reasonably be energized to coil 254, can run efficiently and safely.
In addition, present embodiment also can be implemented with the second embodiment of the second invention in the present invention in the lump.
(the 4th embodiment of the second invention in the present invention)
In 4th embodiment of the second invention in the present invention shown in Figure 16, the current value flow through in coil 254 is detected when the energising from before dehydrating stroke, when its testing result is less than predetermined value, the rotary speed of the cylinder 230 when making dehydrating stroke is difficult to control with rising.
Specifically, now, as the current value testing agency detecting the current value flow through in coil 254 when the energising from before dehydrating stroke, although not shown, but there is such as current sensor.
Before dehydrating stroke (during washing stroke), first, start to be energized (step S201) to coil 254, then current value (step S202) is detected by above-mentioned current sensor, afterwards, judge whether its testing result (current value detected) is 0 (step S203).
In above-mentioned steps S203, if be judged as 0 ("Yes"), then carry out mistake display (step S204) at guidance panel 24, (step S205) out of service.
Relative to this, in step S203, if be judged as that the current value detected is not 0 ("No"), then then judge testing result in described step S202 whether than 50% little (step S206) of the predetermined current value flow through before this dehydrating stroke, if be judged as little ("Yes"), then stop the energising (step S207) to coil 254, return step S202.
In step S206, if be judged as not little ("No"), then then judge testing result in described step S202 whether than 80% little (step S208) of the predetermined current value flow through before this dehydrating stroke.
If be judged as little ("Yes"), then carry out the change controlled in the following manner, which is: make that the rotary speed of the cylinder 230 determined in dehydrating stroke could rise, reduce about the threshold value of the vibratory output of tank 226, or reduce the climbing (step S209) of rotary speed of cylinder 230.
Therefore, under these circumstances, as the vibration detection mechanism of the vibration of detection tank 226, there is the vibrating sensor of not shown acceleration transducer etc., or control device 225 has the program of the climbing of the rotary speed changing cylinder 230.
If in the control content of above-mentioned steps S209, reduce to determine that the rotary speed of cylinder 230 could rise, about the threshold value of the vibratory output of tank 226, then the rotary speed of cylinder 230 is difficult to rise.
In addition, even if the control that the climbing carrying out the rotary speed making cylinder 230 reduces, the rotary speed of cylinder 230 is also difficult to rise.Namely, in any one situation, control that the rotary speed of all carrying out the cylinder 230 when making dehydrating stroke is difficult to rise (when Figure 17 represents the control carrying out the climbing of the rotary speed of cylinder 230 is reduced, the time dependent situation of rotary speed of cylinder 230).
Relative to this, in step S208, if be judged as not little ("No"), then until stroke (dehydrating stroke, rinsing stroke, final dewatering stroke, dry trip) afterwards proceeds the energising (step S210) to coil 254 with respective predetermined current value.
Then, afterwards, judge whether running time terminates (step S211), if be judged as not terminating ("No"), then return step S210, if be judged as terminating ("Yes"), then terminate the energising (step S212) to coil 254.
As previously mentioned, if the temperature because of environment for use is high and/or the frequency of the adjustment of the damping force of damper 241 makes greatly the temperature of coil 254 raise, then the electric current flow through in coil 254 reduces, consequently, be difficult to the damping force increasing damper 241, be difficult to the vibration suppressing tank 226.
Relative to this, as in the present embodiment, the current value flow through in coil 254 is detected when the energising from before dehydrating stroke, when its testing result is less than predetermined value, the rotary speed of carrying out the cylinder 230 when making dehydrating stroke is difficult to the control (step S208, S209) of rising, thus reduce the generation of the vibration of tank 226, even if therefore under the situation of damping force that can not increase damper 241, also can improve acceleration, the decelerability of dehydrating stroke, dehydrating stroke can be made smoothly smoothingly to terminate.
In addition, now, according to the result detecting the current value gained flow through in coil 254 when the energising from before dehydrating stroke, when this testing result is 0, carry out mistake display (step S204), and (step S205) out of service, thus security can be increased.
In addition, present embodiment also can be implemented with the second embodiment of the second invention in the present invention in the lump.
