Corresponding collision part 339 or 340 with it is described driving gear collision make the first gear at either one To rotation stop.The driving gear preferably includes the protrusion of the end far from the screw thread 334 on its axis, simultaneously The collision part 339 and 340 collides with the protrusion 335 rather than the screw thread 334.The protrusion is preferably It is non-circular and extended with a lateral supporting leg.Supporting leg 335 and the collision of the end of the collision part 339 and 340 make The rotation of the driving gear stops, and the movement of the first gear is caused to terminate in turn.

When electric motor 332 works, the stopping of sliding tooth wheel rotation causes current of electric quick and detectable Increase.When detecting this quickly increase of current of electric, the voltage acted on the motor can remove, however this Certain motors and power supply combination are not needed to.In the optimum structure of the present invention, the number of a bit Circuit detects the current of electric and exceeds or without departing from threshold value.When digital circuit indicates that the current of electric has exceeded threshold value model When enclosing, then an electric controller closes the power supply to the motor.

Therefore, the collision part 339 and 340 determines the end limit of sports record of the first gear 337.The end fortune The dynamic limit is shown in Figure 10 and 11 respectively.When moving termination, the first gear 337 of Figure 10 is along arrow 345 The rotation in direction will lead to position shown in Figure 11, and rotation of the first gear 337 of Figure 11 along 343 direction of arrow will be led Cause position shown in Fig. 10.

One disk 341 annular for being positioned over the first gear 337 opposite with the collision part 339 and 340 In hole 351.Actuating lever 331 extends through in a hole for one of extending a protrusion by the disk 341.The protrusion It can be slided along the connecting rod 331, while the disk 341 can rotate in the hole 351 in the first gear 337.

When reversely position turns to position shown in Figure 11 to the first gear 337 as shown in Figure 10, the disk 341 The end of the actuating lever 331 is pulled to the other side by the side of the hub 350 along direction shown in arrow 346.This makes institute It states the end that actuating lever 331 is located at around it in rod piece 330 to rotate, so that the rotating bar 330 and the roller Door engaging member 300 is rotated around pivoting strut 302.

When counter motion between position shown in the first gear 337 position and Figure 10 shown in Figure 11, the company The end 342 of extension bar 331 is pulled along the direction of arrow 344, so that the drum hatch engaging member 300 is by its bound site It sets and turns to disengaged position.

Controller

Referring to Figure 12, the drying machine for clothes of the present invention includes an electronic controller 900, and the electronic controller 900 is compiled There is program, to according to user's input and the work of sensor output control machine.The electronic controller 900 includes Fig. 1 In a PCB installation electronic building brick 139.Specifically, the controller 900 controls the drum drive motor 902 Velocity of rotation and direction, the drum hatch engaging member activate motor 332 in the rotation of both direction, drum cover locking solenoid 918 work and do not work and the work of a heater 930 (gas or electrical component).The controller is by user's input face Plate 916 receives user instructions (input), and the condition of dryer circulate operation necessary to the input is normally set up is (for example, rise Begin the time, circulation time, required aridity and operation temperature) and operation and control (for example, starting, stop, pause and into Enter tranquil pattern).The controller 900 receives other inputs, and the input carrys out self-induction and passes through the drum cover locking spiral shell The current-sensing circuit 906 (indicating whether the drum cover closes) of the electric current of spool, humidity sensor 680, induction By the current-sensing circuit 914 of the electric current of the motor 332, the output of an optical sensor 910 indicates the bowl temperature The output of one electro-hot regulator 912, detect the output of a temperature-adjusting device 932 of the temperature overheating in the roller with And the arbitrary monitoring output of the mounted heater assembly.

The common spin-drying operation of the dryer not describes herein.The dryer once in an operation mode, Then the best operation mode includes the roller in the direction rotation process for applying heat to the air of entrance along one Cycle appropriate, wherein the rotation in the direction is briefly rotated along another direction for not applying heat (or applying a small amount of heat) After a period of time.Specifically, when the driving motor drives the fan along its more effectively direction rotation, it is described Heat preferably individually applies.If using separation motor come driving drum and fan, applying heat to the air of entrance can be complete It is carried out entirely independently of the rotation direction of the roller.

The humidity of clothing in a dryer should be detected by the resistance sense between a pair of of conductive contacts object to this field Technical staff for be well known, therefore herein not describe.When the humidity incuded is less than or equal to selected by user Humidity value when, the controller, which is preferably such that, to be entered tranquility by the dryer (roller rotates, on the air flowed through Heat is not acted on).It will be apparent that the method (such as air exit temp distribution and air outlet slit humidity) of other detection humidity Can be used, in all cases, user selection humidity value correspond to do not wash or the value of processed sensor rather than Absolute humidity.Roller cover lock and its together with the operation of a lid sensor circuit be well known to those skilled in the art (the especially washing machine of top placement clothing), therefore not describe herein.Much less, it is closed in one in no instruction lid In the case of the sensor of state, the controller constitutes the locking operated to the machine, at the same its make it is described It covers and is in a lockup state during whole operation.

The roller for constituting the dryer of the part of the present invention is opened and closed and connected below with reference to figure The operating method of initialization program after power supply and its corresponding most preferred embodiment are described by.

General operation

The unlatch and close operation and an initialization program of the dryer include to the roller from and/or to The speed control operation for the turned position known and drive to the drum hatch engaging member between retraction and extended position It is dynamic.

The optical sensor 910 incudes the position of the roller.Referring to Fig. 5 Q and 5B, the roller end 726 include by 950 ring row of dent of its surface rolling.During the roller rotates, the periphery of the dent at least so that from it is adjacent it The light of optical sensor 910 scatters.950 regular interval of the dent is arranged, and in entire ring row, an only dent is wrong From its expected position.One position monitoring arithmetic unit increases or decreases a roller that can change with each dent of process Position (according to roller rotation direction).One mistake shows the wrong longer interruption letter from dent from the detection of dent detection circuit Number, based on it is described it is wrong from dent increase or decrease the variable position, while being reset when needed using the detection The variable position.The position be derived from it is described it is wrong from dent, the unlatching relative to such as described roller opening Be a known turned position for the other structures feature of the roller of closed edge.

The controller is not necessarily to monitor cylinder position in entire normal spin-drying operation, this is because when needed, institute Stating cylinder position can re-establish within the scope of one of roller complete rotation.

The Rolling motor is preferably an AC induction motor.Applied exchange is limited by a variable duty cycle To change the alternating voltage of the useful effect, the rotating speed of the drum drive motor is able to controlled to implement to beat on and off voltage Closed operation.The drum rotation speed can be that the optical sensor continuously incudes.Caused by light from the dispersion at the dent of roller end The cycle interruption of the received light of optical sensor is detected.The speed of the interruption and the drum rotation speed are at direct ratio known to one. The controller is by monitoring the relationship interrupted between determining drum rotation speed described in the drum rotation speed and opening operation And the working cycles are controlled, so that the drum rotation speed is maintained at or close to the desired roller opening speed.

In addition, the rotating speed of the drum drive motor can be by from one of rectification power supply frequency conversion inverter operation Control.

The controller determines the roller still in rotation by regular continuous interrupt of the photosensor signal State is necessary.Timer for the wrong detection interrupt interval from dent detection circuit is from last time signal The disconnected past time indicates the stopping of the roller rotation when having exceeded a scheduled limit.The limit can be one pre- Fixed period or from previous interrupt interval.

For the driving of the roller engaging member, the operation of actuator motor has been described by, including passing through The electric current induction of institute's actuator driving motor driving current detects the end points.In addition, in the actuator driving motor work During work, used time during the controller tracks the initialization of the actuator motor and the motor stops. Time used is compared by the controller with a desired range.Described in time used indicates except the desired extent The possibility of drum hatch engaging member not exclusively to work.

The roller opening operation that the dryer is implemented

The roller opening operation is explained below with reference to the cross section of Figure 12 and 15 and Fig. 6-9.

One roller opening operation is usually implemented in the terminal of a dryer cycle period.In the roller opening operation Initial period, the roller are usually rotated with an operating rate.In step 1001, the controller determine the roller whether It is rotated in the drum door open system.If the roller rotates forward (counter-clockwise direction of Fig. 6), in step 1010, The controller makes the roller stop operating, and is allowed to rotate backward again (Fig. 6 is clockwise).Once in step 1001 detect the roller along rotation is correctly oriented, then the drum opening operation starts.

In step 1002, the controller makes the rotating speed of the drum drive motor reduce.The velocity of rotation is in step Rapid 1003 is measured, and in step 1002 further such that the drum rotation speed, which reduces until up to a roller, opens safety Rotating speed.The controller continues thereafter with so that the speed that the roller reduces with one rotates up in step 1004 and 1005 Detect that the roller has arrived at the safe turned position extended convenient for the drum hatch engaging member.The position is set Surely it is preferably such that the drum hatch engaging member reaches the position of a full extension with the roller, and then is combined in the drum door Before, the roller need to only slowly run a shorter distance.

In step 1006, the controller encourages the actuating motor 323 so that the drum hatch engaging member rotation is gone forward side by side Enter the binding site, while the outer edge of the tooth of the ramped abutment is slided in the outer surface of the drum housing.In step 1007, the controller detects the first gear arm 339 and the drive by the increase of the electric current of the actuator motor 323 The time point that moving gear protrusion 335 collides.The excitation that the controller measures step 1006 starts to stop with actuator motor The time interval of period, and determine the interval whether within the scope of one is scheduled in step 1007.If the interval Within the scope of one is scheduled, then in step 1009, the controller encourages the drum door combination motor, and continues its journey Sequence.If the interval exceeds a scheduled range, show possibility existing for failure, therefore in step 1008, the control Device either stops the operation of machine and shows an alarm or enter a recovery routine.

As the rotation of the roller makes the inclination of the leading edge and the drum hatch engaging member of the drum door Bearing combines, and the drum hatch engaging member immediately enters extended position as shown in Figure 7.Pass through further turning for the roller It is dynamic, the front end of the ramped abutment tooth the catch member 201 of the T shapes pivotal arm lower section sliding up to its turn up against The joint face 313 of the plate.In this point, the catch member 201 can not possibly further along be transported relative to the drum hatch engaging member It is dynamic, therefore the movement of the drum door terminates, but the roller is rotated further.Described on the ramped abutment edge Catch member 201 is simultaneously promoted the catch member by adjacent cylinder surface.The roller is relative to the drum door into one The rotation of step makes the catch member 201 be located on drum door support wing passage.The wing passage makes the catch member 201 are in a state pivoted out, while the roller is open or partially open.As the description carried out with reference to Figure 33 A, institute It states the lateral wing plate of one of roller engaging member and opens and close in manipulation process in roller and be located in the wing passage 109 to support It states plate and is allowed to position.

Referring to Figure 15, in step 1011 and 1012, the controller continue to encourage the drum drive motor so that The roller rotates up to the stopping that the controller detects in step 1012 rotation of the roller with opening speed.

The controller continues to monitor the speed that the photosensor signal is interrupted, to determine the roller in step 1012 The time to stop operating.The controller can also have there are one for monitoring the current-sensing circuit of the current of electric, to Quick by current of electric increases the stopping for determining that the motor rotates.

One bearing of 330 bottom side of the drum hatch engaging member and the outer surface stretching by the wing passage 109 The contact of one stopping bearing is so that the rotation of the roller tapers off.

The controller encourages the drum driven once the stopping for detecting the roller rotation in step 1012, then its Motor.In step 1013, the controller determines whether the roller has arrived at one according to the roller current location of its calculating A position fully opened.If it is, in step 1015, the controller makes the work of the machine stop and makes institute State the separation of roller cover lock.If the control determine that the roller does not reach a drum door open position, then in step 1014, the controller makes the work of the machine stop and shows alarm or enter a reforestation practices.

A brake mechanically or electrically may be used for the controller so that the roller keeps its open position.Institute It may include the resistance connected across the drum drive motor coil to state brake for example.

The roller shutoff operation that the dryer is implemented

The roller shutoff operation is substantially opposite with the drum opening operation.Below with reference to Figure 12 and 16 and figure The cross section of 6-9 is explained the roller shutoff operation.

During a roller shutoff operation, the controller encourages before closing the roller in step 1020 described Drum cover locking solenoid, and confirm that the roller cover lock is successfully driven in step 1020.If the roller cover lock is not It is successfully driven, then the drum cover locking solenoid is disconnected in step 1024, while user alarm is activated.

Once the roller cover lock has been started up successfully, then the shutoff operation sets about implementing to include step 1026, The 1028 and 1030 slow shutoff operation of roller.

In step 1026, the controller encourages the drum drive motor so that the roller is along roller closing direction It is rotated with a roller closing velocity.

The controller continues to encourage the drum drive motor so that the roller is straight with the rotation of roller closing velocity Extremely detect that the roller is more than a drum door closed position in step 1030.

Between the step 1026 of each cycle and 1030, the controller determines that the roller is still located in step 1028 In rotary state.If it detects that the roller has stopped, the controller implements an error trapping operation, passes through Step 1032 is cut off the driving motor and is stopped by the rotation of the roller.Then the controller implements one Roller opening operation including step 1034 and 1036.In step 1034, the controller encourage the driving motor so that It obtains the roller to rotate with a roller opening speed along roller opening direction, in step 1036 not rotating by the roller To detect the completion of the opening operation.The roller opening operation of salvage is played once completing, then in step 1038, institute It states machine to be stopped, while user's alarm is activated.In addition, the controller can be configured to return to the step 1026, and retry the shutoff operation.

In step 1030, once detecting that the roller has arrived at the closed position, then the controller is in step Motor 323 is activated described in 1040 reverse energizations, so that the roller engaging member enters disengaged position.It is described in step 1042 Controller detects the stopping of the actuating motor work and motor actuating time used compares with a desired range. If the time used exceeds desired range, the controller is in step 1046 so that the work of the machine stops and opens Dynamic user alarm.In addition, the controller can be configured to enter a recovery operation.If the time used is in institute Within the scope of desired, then in step 1044, the controller disconnects the motor 323.Then in step 1048, the control Device starts a drying duty-cycle operation comprising by stopping the limit to the driving voltage of the drum drive motor It makes and the roller is accelerated until normal service speed.

Thus during the shutoff operation of the roller, the roller is by static with a forward direction (in Fig. 9 Counter-clockwise direction) rotation, while the drum hatch engaging member makes the drum door remains stationary.The roller continues to roll Cylinder closing velocity rotation (preferably identical as the roller opening speed) is until form the described of the back edge of the roller opening The leading edge of blade reaches the leading edge of the drum door.At this point, the catch member 201 is by the dimple close to the drum blade leading edge The outer surface of the side tracks at place falls, and another location is pulled to by the spring part 230.This allow for the drum door with The drum hatch engaging member separation.Cannot pass through the catch member of the siding track end prevents the roller in one direction The closed positions Men Youqi are slided, and the leading edge 182 against the drum blade leading edge prevents the rolling in another direction Tube door is slided by its closed position.

As shown in figure 33 a, in the roller down periods, if the opening accompanies thing, the catch member 201 is not The dimple can be reached, the outer surface of the siding track is still located at and is supported by the closing bearing of the door 300.Accordingly Ground, the drum door are still connected with the static body, at the same the bearing and the drum door against making the rolling The rotation of cylinder stops.The controller detects the stopping of the roller rotation and is allowed to rotate and be again turned on, in order to user It can debug.

Initialization program

Even if usually when the dryer does not work, the controller is also at working condition.In a soft power cut Under pattern, the controller continues to keep the record of roller current location and drum hatch engaging member position in memory.However If machine is by hard power cut, these positions record will be lost, such as be included in one occurred in initial installation process Lock in power supply interruption or wall is closed or bolt is unplugged.

After a hard reset, in order to form a correct state value, the controller implements an initialization program.Figure 17 Show the initialization program

The initialization program is by a roller shutoff operation of the step 1020 corresponding to Figure 16 to 1038.

Specifically, in step 1050, the controller encourages the drum cover locking solenoid, while in step 1052 The correct actuating of the roller cover lock is detected, if the roller cover lock is unbonded, in step 1054 so that the machine Work stop and start user alarm.If the roller cover lock correctly combines, the controller executes step 1056,1058 and 1060 roller shutoff operation.Step 1060 and step 1030 difference of normal switching-off operation exist In door is opened completely as described in excessively, then it, which only detects the roller and has turned to one, is sufficient to make the door to close completely The angle closed.Before step 1060 determines that the roller has gone to the angle for making door closing, if the controller exists Step 1058 detects that the roller has stopped, then it makes the rotation of the roller stop and starts step in step 1062 1064 and 1066 drum opening operation.It starts roller rotating up in step 1066 along door opening direction in step 1064 Middle determining roller stops operating when machine is stopped, while starting user alarm in step 1068.

If the controller determines that the rotation of the roller has made the door close in step 1060, in step 1070, the controller disconnects the drum drive motor.It is assumed that the roller be now arranged in one it is unrelated with its initial state Closed state.

In step 1072, the controller in rotational direction encourages the drum hatch engaging member actuating motor, so that institute State drum hatch engaging member retraction.In step 1074, the controller determines whether the actuator driving motor is shorter at one Time in, be actually stopped at once, if it is, carry out step 1076 to 1088 subprogram.

If the motor is not to stop immediately, in step 1090, the controller determines that the actuator motor is No stopped in a maximum time range.If it is not, then in step 1092, the controller makes the machine Work stops and starts user's alarm.If the actuator motor has stopped within a maximum time, in step Rapid 1094, the controller stops the excitation to the actuator motor, while along so that the side that the roller engaging member advances To encouraging the actuator motor again.In step 1096, whether the controller determines the actuator motor in an expection institute With stopping operating in time range, if it is not, then going to step 1098 so that the work of the machine stops and starts a use It alarms at family.If the controller determines the drum hatch engaging member motor in expected time range in step 1096 Stop, then in step 1100, the controller stops the excitation to the actuator motor, while along so that the roller knot Encourage the actuator motor again in the direction of component retraction, while detecting the actuator motor in step 1102 and stopping turning Whether the dynamic time used is in the range of an expection.If the controller detects the time used beyond expection in step 1102 Time range, then in step 1104, the controller work of the machine is stopped and start a user alarm.Instead It, then in step 1106, the controller starts the opening operation shown in Figure 15.

If the controller determines that the actuator motor is stopped immediately according to initial excitation in step 1074, Then in step 1076, the controller stops the excitation to the actuator motor, while along so that before the roller engaging member Into direction encourage the actuator motor again.The controller is determined in step 1078 encourages the actuator in step 1076 Motor and the motor be stopped during used in the time whether fall into the range of an expection.If it is not, then the control Device processed is in step 1080 so that the work of the machine stops and starts user alarm.If used in being determined in step 1078 Time, then in step 1082, the controller stopped the excitation to the actuator motor, together within expected time range When along so that the actuator motor is encouraged in the direction of roller engaging member retraction again.The controller is determined in step 1084 Whether the time used in during step 1082 encourages the actuator motor and the motor to be stopped falls into expected from one In range.If it is not, then the controller makes the work of the machine stop and starts user alarm in step 1086. Conversely, then in step 1088, the controller makes the actuator motor disconnect, and comes into effect a drying program, Include so that the drum drive motor is rotated with a normal opening speed.If the initialization program shows a roller Closed position, while the drum hatch engaging member is retracted, then the automatic implementation of a drying program may be a permanent storage In a user select setting.This is a useful selection, ensures that the operation being interfered due to power cut is not necessarily to The interference of user can be completed.
