According to embodiment of the present utility model, Valve controlling part comprises further: rotary driving part 4, exports clutch part 5, drive disk assembly 6, linkage part 7, spin balancing parts 8, brake component 9.
Specifically, rotary driving part 4 can be the gear or gear train that are driven by motor output shaft.
Export clutch part 5 and comprise spacing clutch part 51, castle wheel sheet 52, clutch is non-return takes turns 53, planetary gears 54 and clutch check rod 55.
Drive disk assembly 6 can comprise one or more output transition wheel 61, forms train of reduction gears.
Draining valve control motor can be integrated in this drain control unit.
During electrical power, the sliding contacting part of spacing clutch part 51 is connected with the slide wall portion of output shaft gear 31, and therefore under the effect of spacing clutch part 51, castle wheel sheet 52 and clutch be non-return to be taken turns 53 and engage.So, the rotary driving force of rotary driving part 4, by planetary gears 54, export transition wheel 61, output shaft gear 31, send belt wheel 32 to, pull parts 2 (such as, steel wire rope) to be wound, be contained on steel wire rope 2 by operand (spool) 1, can drive from initial position (such as, making the position of valve closing) and be indexed to operating position (making the position of valve opening).
As previously mentioned, motor export driving force through rotary driving part 4, export clutch part 5, drive disk assembly 6, traction element 3, pull parts 2 to be finally passed to by driven object (i.e. spool 1), thus make valve from original position (closed condition) open be operating position (hull-borne).After valve opening to drainage position, the driving force that output clutch part 5 makes motor export no longer is passed to traction element 3.Because drain control unit generally includes valve reset mechanism (such as, be arranged on the spring in valve body), therefore need to control output clutch part 5, while making motor driving force not be passed to traction element 3, drive disk assembly 6, traction element 3, pull parts 2, position when spool 1 remains on valve opening.Linkage part 7, spin balancing parts 8 and brake component 9 compounding practice, realize the control to exporting clutch part 5.
The initiative part of linkage part 7 and follower can comprise permanent magnetism-permanent magnetism, permanent magnetism-magnetic hysteresis, permanent magnetism-electromagnetism, electromagnetism-electromagnetism, magnetic inductive several types.Consider the drain control unit small volume for washing machine, therefore adopt the permanent magnetism-permanent magnetism host-guest architecture being similar to permanent magnet clutch, the host-guest architecture of permanent magnetism-magnetic hysteresis, or the host-guest architecture of magnetic inductive, can save electric excitation, structure is simpler.
More preferably, because the control torque of actual needs is also little, adopt the host-guest architecture of magnetic inductive to realize transmission and clutch, structure can be made more to simplify, and requisite space is less.
According to embodiment of the present utility model, linkage part 7 comprises: magnet steel is taken turns, magnet steel axle tooth, induction pieces 71.Wherein, annular side and the circular end face of induction pieces 71 are integrally formed, and are held within it by magnet steel wheel, and induction pieces 71 and magnet steel wheel are each via non-magnet material (such as, plastics) gear made is connected to same pivot 72, and can with this pivot 72 coaxial rotating.Described pivot 72 can use metal material (such as, iron) to make.The diameter of magnet steel wheel is slightly less than the internal diameter of induction pieces 71, thus can form very little fixed interval (FI) in radial direction between magnet steel wheel and induction pieces 71; Meanwhile, the upper surface of magnet steel wheel also can not contact with the inner surface of the circular end face of induction pieces 71; The gear of magnet steel wheel and the respective core setting of induction pieces 71 can limit their locus, magnet steel is taken turns and can not come in contact with induction pieces 71 and rub when rotated.Magnet steel wheel is made up of permanent magnet material, and induction pieces 71 can be made up of copper or aluminium.When magnet steel wheel High Rotation Speed, induction pieces 71 reversely rotates relative to magnet steel wheel, thus produce eddy current with the magnetic line of force of radial fixed interval (FI) cutting magnet steel wheel, the induced field that eddy current produces and the permanent magnetic field that magnet steel is taken turns interact, so generation interaction force, this active force drives induction pieces 71 to rotate with the direction that magnet steel takes turns direction of rotation identical.
Alternatively, magnet steel axle tooth is taken turns with magnet steel and is directly connected, by rotary driving part 4 rotation directly or drive magnet steel axle tooth spiral to turn, thus drive magnet steel wheel to rotate.
Preferably, between magnet steel axle tooth and magnet steel are taken turns, be connected with torsion spring, the rotation of rotary driving part 4 directly or indirectly drives magnet steel axle tooth spiral to turn, and under the effect of torsion spring and magnet steel axle tooth, magnet steel wheel also rotates.When making rotary driving part 4 stop the rotation when motor stalling, torsion spring can to still realizing buffering at the magnet steel wheel rotated.
Brake component 9 can comprise braked wheel 91 and elasticity recovery part (such as spring, not shown).Wherein, braked wheel 91 is made up of sector gear and the braking parts 911 that is integrally formed at sector gear one side.This braking parts 911 can be mated with control strip 81 contraposition of spin balancing parts 8, thus when braking parts 911 contacts with control strip 81, can stop the rotation of spin balancing parts 8.
When motor rotation, rotary driving part 4 drives shaft coupling transmission to take turns 63 rotations, interlock magnet steel axle tooth spiral turns, thus drive magnet steel wheel to rotate, as the aforementioned mechanism of action, induction pieces 71 rotates with magnet steel wheel, is fixed on the sector gear of the pinion 711 rotary actuation braked wheel 91 on induction pieces 71, makes its counter-rotation to the direction of rotation of rotating wheel 8 under the reset force effect overcoming elasticity recovery part.
Preferably, between the pinion 711 and the sector gear of braked wheel 91 of induction pieces 71, arrange two transmission transition wheels 62, these two transmission transition wheels 62 can play the effect of deceleration, thus control the velocity of rotation of braked wheel 91.
So, when the braking parts 911 of braked wheel 91 turn to contact with the control strip 81 of rotating wheel 8 time, the rotation of spin balancing parts 8 is prevented from, and then the rotation of the external tooth gear of planetary gears 54 is also prevented from.Therefore the rotation of the casing of planetary gears 54 is also prevented from.Be in connection status owing to now exporting clutch part 5, the revolving force of motor is sent on belt wheel 32 by gear reduction group 61 and output shaft gear 31, is indexed to operating position by operand from initial position driving.Alternatively, the braking parts 911 of braked wheel 91 also can obstructed over-rotation equalizing feature 8 and directly act on planetary gears 54.
When the control strip 81 of spin balancing parts 8 is controlled by the braking parts 911 of brake component 9, the magnet steel wheel on the downside of induction pieces 71 becomes idling conditions.Under magnet steel wheel idling conditions, by exporting clutch part 5, also can keep the moment of torsion transmission from motor.Now, brake component 9 keeps the state of braking the control strip 81 of spin balancing parts 8.
After spool 1 is driven into operating position, the sliding contacting part of spacing clutch part 51 is pulled to the direction of rotation of output shaft gear 31 because of the projection effect of output shaft gear 31, spacing clutch part 51 acts on castle wheel sheet 52, remove castle wheel sheet 52 and the clutch on the upside of it non-return take turns 53 engagement state, thus the rotary driving force of rotary driving part 4 is not delivered to, and clutch is non-return to be taken turns on 53.
And at this moment, spool 1 because of self with reset force, start to do homing action to initial position, but because in linkage part 7, magnet steel wheel is for the relative rotation for the induction pieces 71 arranged on the upside of it, still can produce aforesaid magnetic induction force, make induction pieces 71 and brake component 9 remain on application position.Spin balancing parts 8 also remain on by controlled position, thus, as previously mentioned, the periphery gear stall of planetary gears 54, the non-return wheel between 53 and the castle wheel sheet 52 on the downside of it of now clutch is in releasing state of a control, rely on the swing position of spacing clutch part 51, clutch check rod 55 can stop clutch non-return take turns 53 opposite direction rotate.So, can make to be remained on operating position by operand.
When stopping feeding electric motors, rotary driving part 4 stops operating immediately, and through the transmission of shaft coupling transmission wheel 63, magnet steel axle tooth also stops operating.The magnet steel wheel driven by magnet steel axle tooth is also in halted state thereupon.Due to not existing of magnetic induction force, under the reset force effect of the elasticity recovery part of brake component 9, the sector gear of braked wheel 91 drives transition wheel 62 and induction pieces 71 carry out reverse high-speed rotary then return respective initial position.Simultaneously because the braking parts 911 of braked wheel 91 relieves the constraint of the control strip 81 to rotating wheel 8, the casing of planetary gears 54 is in rotatable state.Under the effect of the reset force of spool 1 self, output shaft gear 31, export transition wheel 61, clutch non-return take turns 53 and planetary gear construction 54 steadily rotate under the restriction of rotating wheel 8, make the internal gear system of Valve controlling part turn back to original state, valve also therefore Quick-return to closed condition.
In like manner, when unexpected power-off, the drain control unit according to the utility model embodiment can automatically revert to original state, and valve also can quick closedown.
Fig. 5 a and Fig. 5 b is the three-dimensional view of the different angles after the drain control unit fit on half-shells of Fig. 2.As can be seen from Fig. 5 a and Fig. 5 b, Valve controlling part II is all received within shell, is connected with external electrical by means of only motor power interface 10.As previously mentioned, owing to not having signal feedback mechanism, this motor power interface 10 is only used to draining valve control motor and provides electric power.
Fig. 6 schematically shows the profile of the drain control unit according to another embodiment of the utility model, and Fig. 6 a is the partial enlarged view of Fig. 6.
Comparison diagram 6a and Fig. 2 a is known, embodiment shown in Fig. 6 is compared with the embodiment shown in Fig. 2, difference is only the combination that instead of output shaft gear 31 and belt wheel 32 with output wheel 33, and correspondingly pulls the pull bar of parts 2 rigidity to instead of nonrigid drawstring or stay cord (steel wire rope).Specifically, output wheel 33 is provided with bearing pin 331, bearing pin 331 is inserted in pull bar 2 one end, thus output wheel 33 rotation drives pull bar 2 to move, and changes the position of spool 1.Therefore, can think that the spool control program of Fig. 2 is straight line working method, the scheme of Fig. 6 is rotary mode.
Fig. 7 schematically shows the three-dimensional view after the upper half-shells of drain control unit removal of Fig. 6; Fig. 7 a is the partial enlarged view of Fig. 7.Comparison diagram 7a and Fig. 3 a, Fig. 4 a are known, except aforesaid traction element 3 and pull parts 2 structure except, the principle of the remainder of drain control unit and structure can be identical.
