First coil (internal rotor 40) and the second coil 68 (outer rotor 50) are connected.
First coil 66 (internal rotor 40) is connected by producing the first driver (not shown) of the first drive signal, the
Two coil 68 (outer rotor 50) is connected by producing the second driver (not shown) of the second drive signal.
Examined for example, control unit 500 is based respectively on from the first rotor position formed by hole sensor (Hall sensor)
Survey sensor and the outer rotor 50 of the second rotor position detecting sensor detection (not shown) and the rotation position of internal rotor 40 is come
Apply the control signal of pulsewidth modulation (PWM) mode, the first driver and the second driving to the first driver and the second driver
Device receives control signal to apply the output of U, V, W three-phase to U, V, W three-phase coil of the coil 68 of first coil 66 and second, with this
Rotation driving outer rotor 50 and internal rotor 40.
Hereinafter, reference picture 10 and Figure 11 illustrate the drive unit of washing machine of the present invention and utilize its driving method.
In the case where performing washing or rinsing stroke, above-mentioned control unit 500 drives according to washing or rinsing stroke
The inverter of first driver and the second driver.
Therefore, above-mentioned first driver and the second driver produce three-phase alternating current, produced three-phase alternating current selection
Property independently applies to the coil 68 of first coil 66 and second of stator 60.Thus, by the first coil 66 of stator 60 and
The output of the internal rotor 40 and outer rotor 50 of the driving of second coil 68 is provided with high speed, the revolving force of small torque characteristics respectively.
First, when performing washing or rinsing stroke, if the first coil 66 from the first driver to inner stator applies three
Cross streams electricity, then internal rotor 40 is rotated, and the high speed of internal rotor 40, small torque characteristics are to first be connected with internal rotor 40
Interior axle 30 is transmitted.That is, the output of internal rotor 40 puts on planet as the first input of the first rotating speed by the first interior axle 30
The sun gear 74 of geared system 70.
In the case, if fixing outer rotor 50, the quilt of outer shaft 20 being connected with outer rotor 50 by electronic brake
Fix, and the ring gear 72 being connected with outer shaft 20 will also be fixed.Thus, if the input the from internal rotor 40 to sun gear 74
The first of one rotating speed inputs (i.e., at a high speed, small torque characteristics input) to rotate sun gear 74, then multiple planetary gears 78 are entering
Revolved round the sun during row rotation along the inner peripheral portion of ring gear 72, the planet being connected with the rotary shaft of planetary gear 78
Frame 76 will also be rotated to the direction of rotation identical direction with internal rotor 40.In the case, the rotating speed of planet carrier 76 leads to
Cross according to the gear ratio of the number of gear teeth of sun gear and ring gear setting to be slowed down, produced from planet carrier 76 with low
Speed, the second rotating speed of high pulling torque characteristic.
With epicyclic gearing 70 planet carrier 76 to the second interior axle 32 transmission first export, impeller 130 receive it is vulgar,
High pulling torque is exported, to make washing or rinsing stroke be carried out with high efficiency.
First input of above-mentioned first rotating speed reduces into the first output of the second rotating speed, and moment of torsion then increases, so as to meet
Low speed, high pulling torque characteristic needed for washing stroke and rinsing stroke.
When fixed above-mentioned ring gear 72, the gear ratio obtained from the planet carrier 78 of epicyclic gearing 70 (that is, is slowed down
Than) determined according to following mathematical expression 1.
Mathematical expression 1
Wherein, zrFor the number of teeth of ring gear, zsFor the number of teeth of sun gear.
Cut for example, the method for applying electronic brake by the second driver outer rotor 50 and ring gear 72 can be used
Three-phase alternating current or the second coil 68 is produced short circuit that disconnected the second coil 68 from the second driver to stator 60 applies
Stop the method for ring gear 72 being connected with outer rotor 50.
On the other hand, in the present invention, when performing washing or rinsing stroke, by controlling ring gear 72, to replace
The ring gear 72 being connected with outer rotor 50 is fixed by electronic brake, so that the controllable row exported by planet carrier 76
The change rate (being preferably amount of deceleration) of first output of star gear device 70.
That is, the output of outer rotor 50 is applied to put on epicyclic gearing 70 by the first outer shaft 20 as the second input
Ring gear 72.The second input applied to ring gear 72 can be by with into for controlling the first of epicyclic gearing 70 to export
Amount of deceleration control input.
In the case, the direction of rotation of the second input with the direction of rotation of the first input on the contrary, the of the second input
In the case that two rotating speeds are the 1/2 of the first rotating speed of the first input, the of the epicyclic gearing 70 exported by planet carrier 76
The direction of rotation of one output is with the first direction of rotation inputted on the contrary, and the output of 1/5 rotating speed is slowed down into acquisition.For example,
In the epicyclic gearing of sun gear input/planet carrier export structure, for example, the gear ratio of planet carrier output (that is, is slowed down
Than) it is 5:In the case of 1, when the first input is 250RPM, and the second input is (-) 125RPM, planet carrier input is (-)
50RPM。
Also, the direction of rotation of the second input is identical with the direction of rotation of the first input, in the second rotating speed of the second input
In the case of the first rotating speed less than the first input, with the direction of rotation of the first output identically with the direction of rotation of the first input
Obtained by electronic brake using speed reducing ratio and be less than the second rotating speed of the second input as the speed reducing ratio (5 in the case of 0:1) slow down
Rotating speed output.For example, when first input be 800RPM, second input be 200RPM when, planet carrier is output as 320RPM.
As described above, in the present invention, in order to be washed or rinsing stroke, the revolving force of internal rotor 40 is utilized as moving
Power source, when obtaining the first output of the second rotating speed being decelerated from epicyclic gearing 70, is controlled outer by electronic brake
The clockwise direction rotating speed of rotor 50, or control the rotating speed of the first output by making the method for the reverse rotation of outer rotor 50 or positive rotation
And moment of torsion.
In the present invention, in the epicyclic gearing 70 of sun gear input/planet carrier export structure, if planet carrier 76 is defeated
The gear ratio (that is, speed reducing ratio) gone out is 5:1, then be in the rotating speed of the first input inputted from internal rotor 40 to sun gear 74
In the case of 1000RPM, when ring gear 72 is in normal condition, the rotating speed of the first output of epicyclic gearing 70 is
200RPM, if applying 10RPM revolving forces, the rotating speed of the first output of epicyclic gearing 70 to ring gear 72 to clockwise direction
About 208RPM, if applying (-) 10RPM revolving forces to ring gear 72 to reverse direction, the first of epicyclic gearing 70 is defeated
The rotating speed gone out about 190RPM.
As described above, for example, not stationary annular gear 72, to the realization of the direction of rotation identical direction of sun gear 74
10RPM or so minimum rotation, or make ring gear 72 towards the direction of sun gear 74, i.e. with to the rotation with internal rotor 40
Direction in opposite direction realizes that the mode of (-) 10RPM or so reverse rotation makes outer rotor 50 be driven to reverse direction, increasing or
The rotating speed of the first output of the epicyclic gearing 70 exported by planet carrier 76 is reduced, so as to imperceptibly control amount of deceleration.
That is, when inputting the first input of the first rotating speed from internal rotor 40 to sun gear 74, by intermittently releasing electricity
Sub- brake, not fully stationary annular gear 72, if making ring gear 72 to the direction of rotation identical side with sun gear 74
To rotation, then the rotating speed of the first output of the epicyclic gearing 70 based on planet carrier 76, which is more than, is completely fixed ring gear 72
In the case of the second rotating speed, if on the contrary, make ring gear 72 to the direction reverse rotation opposite with the direction of rotation of sun gear 74,
The rotating speed of first output of the epicyclic gearing 70 based on planet carrier 76 is less than the second rotating speed.
In the present invention, in order to be washed or rinsing stroke, when by reducing the first rotating speed applied to sun gear 74
The first input increase during moment of torsion, it is preferable that the second second turn inputted applied by control input to ring gear 72
Speed is configured to be less than the first rotating speed of the first input inputted to sun gear 74.In the case, apply to ring gear 72
Second input direction can with to sun gear 74 applies first input direction it is identical or opposite.
In the case, the direction of the second input applied to ring gear 72 and the first input applied to sun gear 74
It is in opposite direction, to ring gear 72 apply second input the second rotating speed be to sun gear 74 input first input
In the case of the 1/4 of first rotating speed, planet carrier is output as 0RPM, i.e. realize maximum deceleration.
For example, when the first input is 800RPM, and the second input is (-) 200RPM, planet carrier is output as 0RPM.
Also, the direction of the second input applied to ring gear 72 and the direction of the first input inputted to sun gear 74
On the contrary, at first turn that the second rotating speed that second applied to ring gear 72 inputs is the first input inputted to sun gear 74
In the case of the 1/4 of speed, the direction of first input of the direction of planet carrier output with being inputted to sun gear 74 is identical, with annular tooth
Wheel 72 is compared when being in stationary state, can obtain the bigger output being decelerated.
For example, when the first input is 600RPM, and the second input is (-) 87RPM, planet carrier is output as 50.4RPM.
Especially, in the direction of the second input applied to ring gear 72 and the side of the first input inputted to sun gear 74
Reached to the second rotating speed of the second input that is opposite and applying to ring gear 72 defeated more than first inputted to sun gear 74
The first rotating speed entered 1/4 and less than in the case of 1/2, the direction of rotation of planet carrier output with inputted to sun gear 74 first
Input it is in opposite direction, with ring gear 72 be in stationary state when compared with, the output further slowed down can be obtained.
For example, when the first input is 1200RPM, and the second input is (-) 400RPM, planet carrier is output as (-)
80RPM。
On the other hand, when performing dehydrating stroke, epicyclic gearing 70 is special to the output of ring gear 72 high speed, small moment of torsion
Property input come produced by not slowing down in the way of (torque conversion) by planet carrier 78 meet high speed needed for dehydrating stroke, it is small
Second output of torque characteristics.
In the case, epicyclic gearing 70 in order to receive at a high speed, the input of small torque characteristics is come with (the moment of torsion that do not slow down
Conversion) mode exported, sun gear 74 is set to transitory state, i.e. be set to rotatable state, or
Person, makes sun gear 74 be rotated with ring gear 72 towards equidirectional with same rotational speed.
Thus, the second coil 68 from the second driver to external stator applies drive signal, to make (that is, the ring of outer rotor 50
Shape gear 72) rotated with the 1000RPM of high speed, small torque characteristics to clockwise direction, do not apply drive signal to first coil 66, make
Internal rotor 40 is obtained to rotate freely, or, internal rotor 40 is rotated identically with outer rotor 50 with 1000RPM to clockwise direction.
Finally, only to the revolving force of the transmission of ring gear 72 high speed of epicyclic gearing 70, small torque characteristics, or,
If the first revolving force inputted of identical high speed, small torque characteristics is transmitted to ring gear 72 and sun gear 74, by first
Casing bearing 80, the second Casing bearing 82, the 3rd Casing bearing 84 and Quadruplet pipe bearing 86 and the axle of clutch shaft bearing 26 and second
Hold 28 ring gears 72 being rotatably supported or epicyclic gearing 70 is revolved in the way of not slowing down with 1000RPM
Turn.
Therefore, the high speed of ring gear 72, the revolving force of small torque characteristics are transmitted by the second outer shaft 22 to sink 120
To carry out dehydrating stroke, or according to the whole rotation of epicyclic gearing 70, at a high speed, the revolving force of small moment of torsion is by outside second
The interior axle 32 of axle 22 and second carries out dehydrating stroke to sink 120 and the transmission of impeller 130.
Finally, as the high speed of outer rotor 50 and internal rotor 40, the first of small torque characteristics are inputted in epicyclic gearing
Carry out dehydrating stroke in 70 in the way of (torque conversion) to sink 120 and the transmission of impeller 130 not slow down, dehydrating stroke with
High efficiency is carried out.
The effect of the following epicyclic gearing for arranging the present invention.
First, it is in opposite direction that the direction of the input applied to ring gear and sun gear are inputted, with ring gear
Rotating speed is more than sun wheel speed, and the direction of planet carrier output is identical with the direction of ring gear, and is subordinated to turning for ring gear
Speed, and it is proportional to the rotating speed of ring gear, rotating speed more faster than sun wheel speed is obtained with this, is less than in ring gear rotating speed
In the case of sun wheel speed, the direction of planet carrier rotating speed is identical with the direction that ring gear is inputted, the rotating speed with ring gear
It is proportional, it is derived from the rotating speed smaller than sun wheel speed.
Also, the direction of the input applied to ring gear is identical with the direction that sun gear is inputted, with ring gear
Rotating speed is more than sun wheel speed, and the direction of planet carrier output is identical with the direction of ring gear, and is subordinated to turning for ring gear
Speed, and it is proportional to the rotating speed of ring gear, rotating speed more faster than sun wheel speed is obtained with this, is less than in ring gear rotating speed
In the case of sun wheel speed, the direction of planet carrier rotating speed is identical with the direction that ring gear is inputted, more than ring gear rotating speed
And be decelerated in sun wheel speed, it is derived from the rotating speed less than sun wheel speed.
In the present invention, to the ring gear 72 that epicyclic gearing 70 is inserted between the first outer shaft 20 and the second outer shaft 22
And be connected with each other, the second bearing 28 of the second outer shaft 22 of clutch shaft bearing 26 and support of the first outer shaft 20 is supported by can bidirectional rotation
Bearing constitute.
Finally, in the present invention, epicyclic gearing 70 can to bidirectional rotation, this structure have with conventional electronic
The supporting construction that the state of fixed epicyclic gearing is maintained in washing machine or is only rotated for dehydrating stroke to a direction
Different supporting constructions.
In the present invention, epicyclic gearing 70 can bidirectional rotation, therefore, by by birotor bimorph transducer constitute it is double acting
The motor's for washing machine of power structure is next simultaneously or selectively to make sink 120 and impeller 130 be rotated to identical and opposite direction
Form the washing current of various ways.
In the present invention, epicyclic gearing 70 is not in confined state, therefore, to inside sink 120
In the case of the washings put into more than ormal weight, impeller 130 can bearing load, the planet carrier being connected with impeller 130 76
To the effect of brake apparatus.Therefore, when inputting the revolving force of internal rotor 40 to sun gear 74, export and rotate to ring gear 72
Power, revolves with the sink 120 and outer rotor 50 that ring gear 72 is connected to the direction opposite with the direction of rotation of internal rotor 40
Turn, i.e. (CCW) rotates counterclockwise.
But, do not have in the inside of sink 120 washings or washings be less than below setting value in the case of (in ripple
In the case of taking turns 130 no loads or having a small amount of load), the ring gear 72 of epicyclic gearing 70 is in and input and defeated
Go out the state that outer shaft 20,22 and sink 120 are connected, therefore play brake effect, thus, the revolving force of internal rotor 40 to
Sun gear 74 is inputted and exported to planet carrier 76.Therefore, the impeller 130 being connected with planet carrier 76 is revolved with the speed being decelerated
Turn.

If displacement reaches setting value, one or two in impeller 130 and sink 120 is made while being supplied water
It is individual to be rotated (step S50, step S60).In the case where making impeller 130 and sink 120 be rotated, impeller can be made
130 and sink 120 rotated to equidirectional or opposite direction, it is preferable that in order to produce vortex, make impeller 130 and to wash
Groove 120 is washed to rotate round about.
Therefore, draining is carried out while new water is supplied to sink 120, made in impeller 130 and sink 120 extremely
A few driving remains in the residue of washings to remove.Thus the cleaning degree of washings can be improved.
Now, displacement is the amount for the washings discharged from sink 120, and excessive washings are remained in sink 120
In the state of, if being supplied water and being rinsed, cleaning force can be reduced, in the state of excessive water is discharged from sink 120, if making

If being judged as, water supply time reaches setting time, and impeller 130 and sink are stopped while stopping supplying water
120, draining (step S80) is carried out afterwards.That is, control unit 500 start feed water valve 540 come stop supply water, by disconnect for
The drive signal of the coil 68 of first coil 66 and second stops internal rotor 40 and outer rotor 50, stop impeller and sink
Only, and by starting draining valve 550 draining is carried out.
If completing the draining of sink 120, formally it is dehydrated (step S90).
If completing formal dehydration, rinsing stroke (step S100) is carried out.
If moreover, complete rinsing stroke, by with method identical method as described above carry out dehydrating stroke it
Afterwards, (OFF) power supply is closed to complete to wash (step S110).

Journey and dehydrating stroke.
First, open washing machine to be supplied water, if completing to supply water, perform washing stroke (step S10).And
And, if wash time reaches setting time and completes washing stroke, perform middle dehydrating stroke (step S20, step S30).
Middle dehydrating stroke is identical with the middle dehydrating stroke illustrated in the above-described first embodiment, therefore will omit to it
Detailed description.
If dehydrating stroke in the middle of completing, rinsing stroke is divided into and carried out for the first time and for the second time.
In first time rinsing stroke, supplied water to sink 120, and judge whether the output of sink 120 reaches and set
Definite value (step S40, step S50).Wherein, setting value can be set by the water level of water supply time or sink.
In above-mentioned steps S50 deterministic process, in the case where setting setting value by water supply time, control unit
500 opening feed water valves 540 supply water to sink, if water supply start, water supply detection sensor 520 to this detected to
Control unit 500 applies signal.Therefore, control unit 500 carries out timing to judge whether water supply time reaches to water supply time
Setting time.
In the case where setting setting value by water supply time, control unit is according to from the water level for being arranged at sink 120
The signal that detection sensor 510 applies judges whether the water level of sink 120 reaches setting water level.
If the output of sink 120 reaches setting value, make impeller 130 and sink 120 while draining is carried out
In one or two rotated (step S50, step S60).That is, control unit 500 starts draining valve 550 to be arranged
At least one in water, driving outer rotor 50 and internal rotor 40 makes one or two progress in impeller 130 and sink 120
Rotation.
If also, the output of sink 120 reaches setting value, only making one in impeller and sink to be revolved
