The described track 109 of described cylinder 104 stops preventing to hold outside the described catch member 201 end face that contacts with the drum door 108 of described sealing to provide at its front end 320.

Described T type pivotal arm 200 is by making described cylinder rise to a cylinder open position on the described inclination bearing 311 that is positioned at described cylinder conjunction 300.During described cylinder was opened, described catch member 201 did not rise to and contacts with the end face of described track end 320.After opening of described cylinder rotated beginning, along with described plate 300 makes described drum door locate, the described outer end of described catch member 201 was positioned on the described outer surface of described track 109.In this case, they are between surface and described plate 300 outside the described track 109 described 313.At the circumferencial direction of described cylinder, described inclination bearing 311 stops its motion in a direction, and described sealing bearing 310 stops its motion at other direction.Described cylinder open rotation during, described catch member 201 is supported on the described inclination bearing 311.

As shown in Figure 3A, during one of described cylinder shutoff operation, described catch member will be against described sealing bearing 310.In a single day described drum door arrives a complete closing state, and then described catch member 210 will be away from the outer surface of described track 109 under the influence of described spring part 230, and described sealing bearing 310 will be positioned at their top simultaneously.When if described drum door can't be closed because of barrier (for example shown in Figure 33 A), then catch member will still be subjected to clamping above described track 109, and simultaneously described door will link to each other with described body.

Described pivot plate 300 can move between a binding site and a separation point position.When described binding site, the front that acts on of described cylinder conjunction 300 is described.In described separation point position, described cylinder conjunction 300 is switched to and makes its cylinder binding end away from described cylinder surface.

For in operating process, in order to help described cylinder conjunction 300 to remain in a position that holds up described catch member 201, a holding device preferably is set up, so that described plate 300 by with described catch member 201 combinations at first before soon a point near described cylinder, hold in the palm through opening and closing subsequently until described catch member 201 and the described cylinder end pine of closing fully.Referring to Figure 33 A, described holding device can adopt the structure of the wing plate 3310 of a horizontal expansion, and described wing plate is extended by the position that each end of described plate 300 combines with corresponding track 109.For in advance a maintenance is provided, an auxiliary short rail portion 3312 is arranged on the described cylinder outside, and concordant with described track 109.Described auxiliary short rail portion 3312 has an openend 3318 away from described track 109, with entering wherein so that described wing plate 3310 is opened to rotate when beginning one.Described catch member receives recess 3316 makes described part 3312 separate near the end 320 with described track 109, the end 3314 of described tracks 109.When described drum door was closed fully, the described retaining 210 of grabbing was arranged in described recess 3316.The length of described wing plate 3310 is enough to across described recess 3316, thereby guarantees that described plate 300 can not get loose when described wing plate passes described recess.

Below with reference to Figure 10 and Figure 11 the pivot of described drum door conjunction 300 is described.Described plate 300 is subjected to the support of the described post ends 302 of described pivot rods 301, and is subjected to described supporting track 361 supports along the length direction of described pivot rods.Described plate 300 comprises a rod member 330.Described rod member 330 is extended and a bit extending by next-door neighbour's one pivoting strut 302 by described plate 300 places of described conjunction one end of next-door neighbour.Actuator lever 331 and described rod member 330 link to each other with a relation that stops immediately.This connection can be for example to be fixed in the pre-molded passage or over-molded.Described bar 331 has 342, one driving mechanisms of an end can be so that described end laterally moves (shown in arrow 346 and 344) along one.The driving mechanism of described the best need be in the power drive of both direction.

The driving mechanism of described the best comprises a worm drive gear-box with one first gear 337, and described first gear 337 can and comprise outward extending circumferential teeth 338 around a hub portion 350 rotations.Driven wheel 333 comprises a screw thread 334 with tooth 338 engagements of described first gear.Described driven wheel is supported between the described end portion supports wall 336 and by an electric motor 332 and drives.

A rubber blanket can be arranged at the below of described motor, is fixed between described motor and the described housing and pressurized, to absorb vibration.In order to absorb vibration, at least one end of described driven wheel 33 is supported in an elastic support on its corresponding supporting walls 336 simultaneously.For example, as shown in the figure, described far-end can be supported in the bearing, and such as a seat bearing or plastic bearing, described bearing is installed in a rubber installing plate 360 that is arranged in one of described wall 336 hole simultaneously.

Described first gear 337 with and/or the formation of described driven wheel make, in described operating process, force shut-down operation to be positioned at for one and comprise any end that drives track less than complete of rotating of one of described first gear 37.When described first gear arrived its arbitrary rotational limitation, described pressure stopped to realize by the collision of described driven wheel structure and described first gear structure.The best of breed of the described driven wheel and first gear is described below, and it absorbs percussion, but without departing from the present invention, other structure also can be used.For example, the screw thread of described driven wheel can have a square end, and any end of the screw thread of described first gear stops in necessary end locating to lack desired profile of tooth recess.When the square end of described screw thread arrives the described position that does not have a recess, it will collide with the corresponding surface of one of described first gear.

Only a certain proportion of circumferential section of described first gear 337 has peripheral teeth 338.Each end of the toothed region of described first gear 337 of the collision part of outwards placing 339,340 next-door neighbours.Described collision part 339,340 more described peripheral teeth 338 have a bigger diameter.Described collision part 339,340 preferably has certain elasticity at each end of the toothed region of described first gear 337 of next-door neighbour.For example, collision part 339, but 340 preferably by the circumferential back of the toothed region 338 of described first gear 337 along the circumferential direction, with described first gear, 337 alternate parallel ends that extend to the end that is close to described toothed region 338.Therefore, described collision part 339 and 340 elasticity make its end slightly deflect under the effect of transverse pressure.

Corresponding collision part 339 or 340 and the collision of described driven wheel make described first gear stop in the rotation of either direction.Described driven wheel preferably includes and is positioned at it and goes up jut away from the end of described screw thread 334, simultaneously described collision part 339 and 340 and described jut 335 but not described screw thread 334 bump.Described jut is preferably non-circular and extend with a horizontal supporting leg.Supporting leg 335 makes the rotation of described driven wheel stop with the collision of the end of described collision part 339 and 340, and and then causes the motion of described first gear to stop.

When electric motor 332 work, described driven wheel rotates stops to cause current of electric fast and can detectedly increase.When detect current of electric this when increasing fast, the voltage that acts on the described motor can be removed, however this to some motor and power supply combination is and is unwanted.In the present invention's optimum structure, the digital circuit of one one bit detects described current of electric and exceeds or do not exceed threshold value.When digital circuit indicated described current of electric to exceed threshold range, then electric controller cut out the power supply to described motor.

Therefore, described collision part 339 and 340 is determined the end limit of sports record of described first gear 337.Described end limit of sports record is illustrated in Figure 10 and 11 respectively.When motion stops, described first gear 337 of Figure 10 will cause position shown in Figure 11 along the rotation of arrow 345 directions, and described first gear 337 of Figure 11 will cause position shown in Figure 10 along the rotation of arrow 343 directions.

In pan 341 looping pit that is positioned over described first gear 337 351 relative with described collision part 339 and 340.Actuator lever 331 extends through by described pan 341 one of extends in the hole of a jut.Described jut can slide along described connecting rod 331, and described pan 341 can rotate in the hole 351 on described first gear 337 simultaneously.

When described first gear 337 oppositely turns to position shown in Figure 11 by position shown in Figure 10, described pan 341 along direction shown in the arrow 346 with the end of described actuator lever 331 by a layback of described hub portion 350 to opposite side.This makes described actuator lever 331 rotate around the end that it is arranged in described rod member 330, and then makes described dwang 330 and described drum door conjunction 300 rotate around pivoting strut 302.

When described first gear 337 between position shown in Figure 11 and position shown in Figure 10 during counter motion, the end 342 of described connecting rod 331 is spurred by the direction along arrow 344, thereby makes described drum door conjunction 300 turn to the separation point position by its binding site.

General operation

The unlatching of described drier and shutoff operation and an initialize routine comprise to described cylinder from and/or to the speed control operation of known turned position and to being in the driving of the described drum door conjunction indentation and the extended position.

The position of the described cylinder of described optical sensor 910 inductions.Referring to Fig. 5 a and 5b, described cylinder end 726 comprises indenture 950 annular row by its surface compacting.During described cylinder rotated, the feasible at least light from the optical sensor 910 that faces mutually of the periphery of described indenture scattered.Described indenture 950 clocklike is provided with at interval, on full annular row, has only the position of an indenture mistake from its expection.A position monitoring arithmetic unit increases or reduces a cylinder position (according to the cylinder rotation direction) that can change with each indenture of process.Mistake detects from the indenture testing circuit and shows the long interrupt signal of described mistake from indenture, based on described mistake from indenture increase or reduce described variable position, use this detection to reset described variable position when needed simultaneously.Described position read take from described mistake from indenture, it is a known turned position for other architectural features of the described cylinder at the opening and closing edge of all openings of cylinder as described.

Described controller need not to monitor cylinder position in whole normal spin-drying operation, and this is because when needs, described cylinder position can rebulid in one of described cylinder complete rotation scope.

Described Rolling motor is an AC induction motor preferably.The alternating voltage that is applied by a variable-operation loop limit is to change the alternating voltage of described useful effect, and the rotating speed of described drum drive motor is able to controlled to implement to open and close operation.Described drum rotation speed can be responded to continuously for described optical sensor.The cycle interruption of the light that optical sensor receives that the dispersion of light from cylinder end indenture place causes is detected.The speed of described interruption becomes a known direct ratio with described drum rotation speed.Described controller is determined the relation between described drum rotation speed and the described drum rotation speed of opening operation and is controlled described working cycles by monitoring described interruption, so that described drum rotation speed remains on or the cylinder opening speed of approaching described expectation.

In addition, the rotating speed of described drum drive motor can be subjected to the control from one of rectification power supply frequency conversion inversion operation.

Described controller determines that by the regular continuous interruption of described photosensor signal it is necessary that described cylinder still is in rotary state.Be used for described mistake and when the time from the last signal interruption past has exceeded a preestablished limit, indicate stopping of described cylinder rotation from the timer of the detection interrupt interval of indenture testing circuit.The described limit can be a preset time section or be derived from previous interrupt interval.

With regard to the driving of described cylinder conjunction, the operation of actuator motor is described, and detects described end points comprising the induction by current by institute's actuator drive motors drive current.In addition, at described actuator drive motors duration of work, described controller is followed the tracks of the initialization and the described used time of motor stopping period of described actuator motor.Described controller compares the scope of a used time and an expectation.The used time is represented the possibility that not exclusively works of described drum door conjunction outside described desired extent.

Cylinder opening operation to described drier enforcement

Below with reference to Figure 12 and 15 and the cross section of Fig. 6-9 described cylinder opening operation is illustrated.

A cylinder opening operation is implemented at the terminal point of a drier cycle period usually.At the initial period of described cylinder opening operation, described cylinder rotates with an operating rate usually.In step 1001, described controller determines whether described cylinder rotates in described drum door open system.If described cylinder forward rotation (counter-clockwise direction of Fig. 6), then in step 1010, described controller makes described cylinder stop operating, and makes it again backward rotation (clockwise direction of Fig. 6).Rotate along correct direction in case detect described cylinder in step 1001, then described cylinder open operation begins.

In step 1002, described controller makes the rotating speed of described drum drive motor reduce.Described velocity of rotation is determined in step 1003, and further makes described drum rotation speed reduce until to reach a cylinder to open safe speed of rotation in step 1002.Described controller continues to make described cylinder to arrive a safe turned position being convenient to described drum door conjunction extension with a speed rotation that reduces until detect described cylinder in step 1004 and 1005 subsequently.The setting of described position preferably makes described drum door conjunction arrive the position of a full extension with described cylinder, so described drum door in conjunction with before, the described cylinder short distance that only need slowly run.

In step 1006, described controller encourages described activation motor 323, makes described drum door conjunction rotate and enter described binding site, and the outward flange of the tooth of described inclination bearing slides at the outer surface of described drum housing simultaneously.In step 1007, described controller detects the time point of described first gear arm 339 and 335 collisions of described driven wheel jut by the increase of the electric current of described actuator motor 323.Described controller records the excitation beginning of step 1006 and the time interval of actuator motor stopping period, and determines that in step 1007 described interval is whether within a predetermined scope.If described interval is within a scope of being scheduled to, then in step 1009, described controller encourages described drum door in conjunction with motor, and continues its program.If described interval exceeds a predetermined scope, then show the possibility that fault exists, so in step 1008, described controller or stop the operation of machine and show a warning or enter a recovery routine.

Along with the rotation of described cylinder makes the leading edge of described drum door combine with the described inclination bearing of described drum door conjunction, described drum door conjunction enters extended position as shown in Figure 7 immediately.By the further rotation of described cylinder, the front end of described inclination bearing tooth is turned up joint face 313 against described plate in the slid underneath of the described catch member 201 of described T shape pivotal arm until it.In this point, described catch member 201 can not travel forward with respect to described drum door conjunction again, and therefore the motion of described drum door stops, but described cylinder is rotated further.The described catch member 201 that is positioned on the described inclination bearing edge is promoted described catch member simultaneously by the cylinder surface that faces mutually.Described cylinder makes described catch member 201 be positioned on the described drum door support-side passage with respect to the further rotation of described drum door.Described wing passage makes described catch member 201 be in a state that pivots out, and described cylinder is opened or partially opened simultaneously.As the description that reference Figure 33 A is carried out, the horizontal wing plate of one of described cylinder conjunction is opened and is closed at cylinder and is arranged in described wing passage 109 in the manipulation process to support described plate and to make it the location.

Referring to Figure 15, in step 1011 and 1012, described controller continues the described drum drive motor of excitation so that described cylinder rotates the stopping of rotation that detects described cylinder until described controller in step 1012 with opening speed.

Described controller continues the speed that the described photosensor signal of monitoring is interrupted, to determine the time that described cylinder stops operating in step 1012.Described controller also can have a current-sensing circuit that is used to monitor described current of electric, thereby determines stopping of described motor rotation by the quick increase of current of electric.

One of stretching out of bearing of described drum door conjunction 330 bottom sides and the described outer surface by described wing passage 109 stops to contact of bearing makes the rotation of described cylinder stop gradually.

Described controller is once detecting stopping of described cylinder rotation in step 1012, then it encourages described drum drive motor.In step 1013, described controller determines according to the cylinder current location of its calculating whether described cylinder has arrived the position of a complete opening.If then in step 1015, described controller makes the work of described machine stop and making described cylinder cover lock separate.If described controller is determined the position that drum door of described cylinder no show is opened, then in step 1014, described controller makes the work of described machine stop also display alarm or enters a recovery pattern.

Described controller can adopt the brake of machinery or electricity so that described cylinder keeps its enable possition.Described brake for example can comprise a resistance that connects across described drum drive motor coil.

Cylinder shutoff operation to described drier enforcement

Described cylinder shutoff operation is roughly opposite with described cylinder open operation.Below with reference to Figure 12 and 16 and the cross section of Fig. 6-9 described cylinder shutoff operation is illustrated.

In a cylinder shutoff operation process, described controller encouraged described drum cover locking solenoid in step 1020 before cutting out described cylinder, and confirmed that in step 1020 described cylinder cover lock is successfully driven.If described cylinder cover lock is not successfully driven, then described drum cover locking spiral shell suede pipe is disconnected in step 1024, and a User Alarms is activated simultaneously.

In case described cylinder cover lock is successfully started, then described shutoff operation sets about implementing to comprise step 1026,, the slow shutoff operation of 1028 and 1030 cylinder.

In step 1026, described controller encourages described drum drive motor so that described cylinder rotates with a cylinder closing velocity along the cylinder closing direction.

Described controller continues the described drum drive motor of excitation and surpasses a drum door closed position so that described cylinder rotates until detect described cylinder in step 1030 with the cylinder closing velocity.

Between the step 1026 and 1030 of each circulation, described controller determines that in step 1028 described cylinder still is in rotary state.Stop if it detects described cylinder, then described controller is implemented an error trapping operation, and the rotation by cutting off described drive motors in step 1032 by described cylinder stops beginning.Described subsequently controller is implemented a cylinder opening operation that comprises step 1034 and 1036.In step 1034, described controller encourages described drive motors so that described cylinder rotates with a cylinder opening speed along the cylinder opening direction, detects finishing of described open operation in step 1036 by not rotating of described cylinder.Play the described cylinder opening operation of salvage and in a single day finish, then in step 1038, described machine quits work, and a user alarm is activated simultaneously.In addition, described controller can be configured to get back to described step 1026, and the described shutoff operation of retry.

In step 1030, arrived described closed position in case detect described cylinder, then described controller is in the described activation motor 323 of step 1040 reverse energization, so that described cylinder conjunction enters the separation point position.In step 1042, described controller detects stopping of described activation motor work and the used electromechanical actuation time is compared with a desired scope.If the used time exceeds desired scope, then described controller makes the work of described machine stop and starting a User Alarms in step 1046.In addition, described controller can be configured to enter a recovery operation.If the used time, then in step 1044, described controller disconnected described motor 323 within desired scope.Subsequently in step 1048, described controller begins one and dries duty-cycle operation, and it comprises by stopping to make described cylinder quicken until normal service speed to the restriction of the described driving voltage of described drum drive motor.

Thereby in the shutoff operation process of described cylinder, described cylinder is rotated with forward a direction (counter-clockwise direction among Fig. 9) by static beginning, and described drum door conjunction makes described drum door keep static simultaneously.Described cylinder continues to rotate (preferably identical with described cylinder opening speed) arrives described drum door until the leading edge of the antemarginal described blade that forms described cylinder opening leading edge with the cylinder closing velocity.At this moment, described catch member 201 is fallen by surface outside the described side tracks at the dimple place of the described cylinder blade inlet edge of next-door neighbour, is pulled to the another location by described spring part 230.This just makes described drum door separate with described drum door conjunction.The described catch member that can not pass described siding track end prevents that along a direction described drum door from being slided by its closed position, prevents that along other direction described drum door from being slided by its closed position against the described leading edge 182 of described cylinder blade leading edge.

Shown in Figure 33 A, in the described cylinder down periods, if described opening accompanies thing, then described catch member 201 can not arrive described dimple, still is positioned at the outer surface of described siding track and is subjected to the support of the sealing bearing of described door 300.Correspondingly, described drum door still links to each other with described static body, simultaneously described bearing and described drum door against making the rotation of described cylinder stop.Described controller detects that described cylinder rotates stopping and making it to rotate and open once more, so that the user can fix a breakdown.

Initialize routine

Even when described drier was not worked, described controller was also in running order usually.Under a soft power cut pattern, described controller continues to keep the record of cylinder current location and drum door conjunction position in memory.If yet machine by hard power cut, these positions records will be lost, and for example be included in a power supply interruption that takes place in the initial installation process or the lock on the wall is closed or latch is pulled out.

After a hard reset, in order to form a correct state value, described controller is implemented an initialize routine.Figure 17 shows described initialize routine

Described initialize routine is by beginning corresponding to the step 1020 of a Figure 16 cylinder shutoff operation to 1038.

Specifically, in step 1050, described controller encourages described drum cover locking solenoid, detects the correct actuating of described cylinder cover lock simultaneously in step 1052, if the not combination of described cylinder cover lock then makes the work of described machine stop and starting User Alarms in step 1054.If the correct combination of described cylinder cover lock, then described controller execution in step 1056,1058 and 1060 cylinder shutoff operation.Step 1060 is with step 1030 difference of normal shutoff operation, opens fully as door as described in crossing, and then it detects described cylinder and has turned to an angle that is enough to make that described door is closed fully.Before step 1060 determines that described cylinder has gone to feasible angle of closing, stop if described controller detects described cylinder in step 1058, then it makes the rotation of described cylinder stop and beginning the cylinder open operation of step 1064 and 1066 in step 1062.Its rotation of opening direction at step 1064 beginning cylinder along door is until determining that in step 1066 cylinder stops operating, simultaneously in step 1068 startup one User Alarms when machine quits work.

If described controller determines that in step 1060 rotation of described cylinder has made described door close, then in step 1070, described controller disconnects described drum drive motor.Suppose that described cylinder is in a closed condition that has nothing to do with its initial state now.

In step 1072, described controller in rotational direction encourages described drum door conjunction activation motor, so that the withdrawal of described drum door conjunction.In step 1074, described controller is determined described actuator drive motors whether in short time, is actually at once to quit work, if then carry out the subprogram of step 1076 to 1088.

If described motor is not to stop immediately, then in step 1090, described controller determines whether described actuator motor is to stop in the time range of a maximum.If not, then in step 1092, described controller makes the work of described machine stop and starting a User Alarms.If described actuator motor stops in a maximum time scope, then in step 1094, described controller stops the excitation to described actuator motor, encourages described actuator motor again along the direction that makes described cylinder conjunction advance simultaneously.In step 1096, described controller determines whether described actuator motor stops operating in the used time range of an expection, if not, then go to step 1098, make the work of described machine stop and starting a User Alarms.If described controller determines that in step 1096 described drum door conjunction motor stops in the time range of expection, then in step 1100, described controller stops the excitation to described actuator motor, simultaneously along making the direction of described cylinder conjunction retraction encourage described actuator motor again, detect described actuator motor in step 1102 simultaneously and stop operating the used time whether in the scope of an expection.If described controller detects the time range that the used time surpasss the expectation in step 1102, then in step 1104, described controller makes the work of described machine stop and starting a User Alarms.Otherwise then in step 1106, described controller begins open operation shown in Figure 15.

If described controller determines that in step 1074 described actuator motor quits work immediately according to initial excitation, then in step 1076, described controller stops the excitation to described actuator motor, encourages described actuator motor again along the direction that makes described cylinder conjunction advance simultaneously.Described controller determines in step 1078 whether the used time falls in the scope of an expection during step 1076 encourages described actuator motor and described motor to quit work.If not, then described controller makes the work of described machine stop and starting a User Alarms in step 1080.If determine the used time within the time range of expection in step 1078, then in step 1082, described controller stops the excitation to described actuator motor, simultaneously along making the direction of described cylinder conjunction retraction encourage described actuator motor again.Described controller determines in step 1084 whether the used time falls in the scope of an expection during step 1082 encourages described actuator motor and described motor to quit work.If not, then described controller makes the work of described machine stop and starting a User Alarms in step 1086.Otherwise then in step 1088, described controller makes described actuator motor disconnect, and comes into effect a drying program, comprising making described drum drive motor rotate with a normal opening speed.If described initialize routine shows a cylinder closed position, simultaneously described drum door conjunction withdrawal, then the automatic enforcement of a drying program may be that a user in the permanent storage selects setting.This is a useful selection, and it guarantees that the interference that need not the user owing to operation that power cut is interfered can finish.
