Description
Technical field
The present invention relates to a kind of gear motor of washing machine, relate in particular to its output rod reset delay device.
Background technology
In general, gear motor of washing machine is used for driving clutch or drives draining valve in driving shaft switch type washing machine.
From big, existing gear motor by the casing that constitutes outward appearance, be installed in casing inside, the gear of the motor of forming by rotor and stator, the upper end that is positioned at rotor or output cam, with gear or output cam interlock mutually, be subjected to the effect of conduction power of motor and the output blocks such as take-off lever that move are formed.
And this existing gear motor also has the structure that output shaft is advanced according to its purposes, when motor on or the off.
In addition, when using output cam as mentioned above, can make its minute two-step according to the form of output cam, on patent application number 10-1996-19524 number, be documented about this example textural.
The invention put down in writing for patent application number 10-1996-19524 number is that the applicant has proposed application and obtained (the patent number of registration: 10-0179268-00), be a kind of structure that is particularly suitable for driving the gear motor of draining valve of the invention about gear motor of washing machine of power.
But because structure take-off lever when motor off of existing this gear motor of washing machine always will reset into original state, therefore in the time of on the driving shaft that existing structure former state ground is used as washing machine switches with clutch motor or door lock assembly, its existence can cause the shortcoming of following point.
Existing problem when existing once gear motor is applied on the door lock assembly at first is described.
Therefore when gear motor is applied on the door lock assembly, owing on the door blocking section (draw-in groove or projection) is arranged, when gear motor on, can advances and be stuck on the blocking section with the take-off lever of rotor interlock, thereby door lock is lived.
Under the state that door is lockable like this, thereby washing machine is suspended or reasons such as power failure, power line are pulled out, dehydration end are when making power supply on the motor not connect when in the process that dehydration is carried out, pressed the action abort key owing to the user, the take-off lever of existing gear motor always returns to initial position again under the situation that door lock is lived, therefore can be with door-lock opening.
In addition, under the state of door-lock opening, drench pit can be done inertia rotation, when the user opened at the initial stage that drench pit is done the inertia rotation, because drench pit is not to be in the state that rotation number fully lowers, therefore the problem on the safety can take place.
That is to say on the motor even without connecting power supply, cylinder also can be done the inertia rotation of certain hour under action of inertia, dwell time that we can say inertia rotation be with cylinder on the load and the rotation number that are connected increase pro rata, when opening at the initial stage of inertia rotation, because drench pit is not to be in the state that rotation number fully lowers, therefore there is the problem on many safety such as when the user takes out washings, can running into hand.
Below with regard to existing gear motor during as the clutch motor of driving shaft switch type clutch apparatus existing problem illustrated.
Up-to-dately a kind of BLDC motor that not only utilizes occurred, also the power conducting path has been controlled respectively, thereby when washing, the agitator low speed rotation is washed, made agitator and the drench pit structure that dewaters of rotation at a high speed simultaneously during dehydration.
Gear motor is to can be used as the clutch motor that drives this driving shaft switch type clutch apparatus that is used for sliding to come usefulness, here be applied on the door lock assembly differently with gear motor, it has been designed to the structure that when motor on take-off lever can be pulled to gear motor one side.
But, because in a single day power supply thereon connects the structure that take-off lever will return to initial position to be a kind of connection as the gear motor of clutch motor or motor like this, therefore when instantaneous power failure occurring under the washing state that is having only the agitator rotation, carriage can descend, and can cause the problems such as breakage of the sawtooth of carriage thus.
Summary of the invention
In order to overcome the shortcoming that prior art exists, the invention provides a kind of output rod reset delay device of gear motor of washing machine, postpone to make again after the certain hour structure of the output rod reset delay device of the gear motor of washing machine that the take-off lever of gear motor is initialised when it can disconnect (off) at power supply.。

The specific embodiment
The present invention is comprising stator (12) and rotor (11), the drive shaft rotating (81) along with the rotation of rotor (11), the take-off lever (5) that interlock moves along with the rotation of driving shaft (81), and take-off lever (5) is advanced, thereby power supply can make take-off lever (5) when disconnecting retreat in the gear motor (1) that returns to initial position, the rotational delay that utilizes gear ratio to make rotor (11) is being arranged and to the gear string (gear train) of output shaft (5) conduction be installed between any two gears of formation gear string between rotor (11) and the output shaft (5), make by slip input gear rotational delay and to the guided rings sub-assembly of the gear of output conduction.
Here, described gear string comprise the upper end of the rotor (11) that is connected gear motor (1) the 1st gear (21), with the 2nd gear (22) of the 1st gear (21) phase interlock, be installed on the axle identical with the central shaft of the 2nd gear (22) can be in the top of the 2nd gear (22) along axle slide and with the 3rd gear (41) of other speed rotation, and with the 4th gear (42) of the 3rd gear (41) phase interlock, and the output shaft gear (43) of the 4th gear (42) phase interlock and constituting.
In addition, described guided rings sub-assembly by between the 2nd gear (22) that is installed in the gear string and the 3rd gear (41) and with the 2nd gear (22) undergear of interlock (23) mutually, be installed in the rotor (32) on the top of undergear (23), certain intervals is arranged be installed in the outside of rotor (32) and the guided rings (33) that rotor (32) can be surrounded, there is guided rings (33) fixed thereon and can be with the guided rings gear (34) of guided rings (33) rotation, there is certain intervals that the elastomeric material (31) that rotor (32) lifts to top is constituted between rotor (32) and the undergear (23) for making.
Described guided rings (33) is made with the material of good conductivity such as aluminium or copper, and what elastomeric material (31) adopted is the compression spring that there is clamp structures at two ends.
In addition, on the take-off lever of interlock (5) tooth bar is being arranged mutually with output shaft gear (43).
And between the stiff end (9) at an end of the take-off lever of interlock (5) and take-off lever rear return spring (6) is being housed mutually with output shaft gear (43).What here return spring adopted is to stretch spring.
In addition, unaccounted symbol 81 to 85 is the central shafts that come usefulness as the pivot of each gear.
Be used on the door lock assembly with gear motor below that to be example illustrated the course of action of gear motor of the present invention.
At first illustrate for door lock being lived the process that take-off lever (5) moves forward.
If go up the connection power supply at terminal shown in Figure 1 (3), on stator (12), just have electric current so and flow through, rotor (11) will rotate.
At this moment, the 1st gear (21) that is connected on the rotor (11) can rotate, the 2nd gear (22), the undergear (23) of interlock also can rotate mutually with it, meanwhile, for the spring (31) that keeps certain intervals between undergear (23) and the rotor (11) and be provided with also can be rotated by interlock.
And, if the permanent magnet that under the effect of spring, constitutes---rotor (32) rotation by N, the S utmost point, according to " my ancient disk " principle (following), the cylindrical guide ring (material with good conductivity such as aluminium or copper is made) in rotor (32) outside also can rotate thereupon so.At this moment the revolving force of guided rings (33) is directly proportional with the magnetic figure of rotation number and permanent magnet.
In addition, if guided rings (33) rotation, so by the guided rings gear (34) of fixing guided rings (33) and the 3rd gear (41), the 4th gear that constitutes reduction part, rotation number can reduce and torque meeting increase, thereby can make output shaft gear (43) rotation, output shaft gear (43) can promote to have possessed the take-off lever (5) of tooth bar (Fig. 3) thus.
Therefore at this moment, the return spring (6) that a side end is fixed on the stiff end (9) can be elongated, if take-off lever (5) advances a certain amount ofly, guided rings (33) can not be rotated and stop again so.
But even in this state, because gear motor (1) also is in the on state, so permanent magnet---rotor (32) also can continue rotation.
Promptly be stuck in the groove of door and can not move on, can hang up load guided rings (33) on, so rotor (32) can be with respect to guided rings (33) slide (slip) and rotates along with take-off lever (5).
On the other hand, go-ahead take-off lever (5) thus along with the end meeting of advancing combines the state that keeps keyed with hole or projection (not shown) on being formed at door.
In a word, the purpose that take-off lever (5) is advanced in order to realize locking a door, power can be transmitted to from rotor (11) is transmitted to gear motor (1) via the gear that is installed in several deceleration usefulness between the output shaft gear (43) and guided rings sub-assembly driving force the process till take-off lever (5) is gone up can produce the time delay of several seconds (sec) and even tens of seconds.
The following describes take-off lever (5) returns to original state in order to open door lock process.
As mentioned above, if possessing power supply off under the state that is lockable of revolving force between guided rings (33) and the rotor (32), the rotation of rotor (11) will stop so, and the rotor (32) in guided rings this moment (33) also can stop.The revolving force of guided rings (33) has also just disappeared thereupon.
Thus, under the effect of the recuperability of return spring (6), output shaft gear (43), the 3rd, 4 gears (41,42) and guided rings (33), guided rings gear (34) thus can carry out contrary rotation restores take-off lever (5).
Equally, when opening door lock like this, restore,, therefore conduct the delay of come also can produce several seconds and even tens of seconds from rotor (11) owing between output shaft gear (43), possessed the gear and the guided rings (33) of several deceleration usefulness in order to make take-off lever (5).
Therefore utilize this effect can be in the process that dehydration is carried out owing to have a power failure etc. former thereby the dwell time of drench pit prolonged when making power supply off, thereby open door lock under the situation under can fully reducing in the rotary speed of drench pit, reach the purpose of safety that guarantees the user.
In addition, Fig. 3 is the device of the present invention time of washing machine in dehydration and curve map of the relation of rotation number when being applied on the door lock assembly of roller washing machine, interval 1 can satisfy the rotation number interval of several seconds as the motor dwell time, and door is in the state of not locking.
Interval 2 is rotation number intervals that the motor dwell time is not satisfied, and interval 3 is of the present invention locking a door between delay zone.
In addition, interval 4 stop the needed time as drench pit can satisfy the interval of several seconds, be defined as the interval that door lock is opened and can opens the door, interval 5 as with interval altogether, interval 3 and interval 4, is defined as the interval that begins to brake owing to reasons such as power supplys such as power failure are cut off.
Illustrated below by the course of action of curve map the door lock assembly in Design of device background of the present invention and the washing process.
At first, when washing machine dewatered, the drench pit in the rotation wants to stop needed the regular hour.Here, dwell time is that load and rotation number with drench pit increases pro rata.
But in utilizing the washing machine of electric braking, when being cut off, in order to shorten the burden of dwell time existence with the output increasing of motor owing to reason power supplys such as power failures.
And utilize in can be in the rotation number of drench pit lower interval of the action delaying type door lock assembly adopted gear motor of the present invention (1) door is opened.
Just in the interval on curve map 1, when stopping, satisfying in the rotation number of dwell time making door not be lockable (perception motor rotation number), and make door lock assembly realize action changing on interval 2 the time point by interval 1.Consider the time delay of door lock assembly here, and make the action of locking a door begin to carry out at interval 1 maximal end point.
In interval 2, only realize locking a door action, door can not be opened, and interval 3 starting point (promptly owing to cut time points of reason power supply such as power failure) upward the motor realization brake.The electric power that is produced when here, motor generation inertia being rotated during motor braking uses as power source.
In addition, door lock assembly of the present invention just can be opened door in interval 3 arrival interval 4 of process through owing to reason power supplys such as power failure cut interval 3 restore.
Take-off lever (5) restored at once when the door lock assembly of existing solenoid type was cut off owing to power supply, thereby the interval that door can be opened is interval 5, drench pit is to rotate at a high speed in the interval 3 that is included in interval 5, and therefore in this is interval door being opened is danger close for consumers.Therefore the dwell time that need accomplish to enter into drench pit just can be opened door after satisfying in the interval 4 of several seconds, only in this way could guarantee that the consumer takes out washings under lower rotation number safely.
As shown in Figure 4, if permanent magnet is moved in the direction of arrows, disk (conductor) also can rotate along the direction that permanent magnet moves so.
If from the aspect explanation of electricity is exactly because the magnetic line of force that forms because of magnet moves with magnet, thereby disk (conductor) meeting cutting magnetic line, in disk, can induce electric current and electric current (I) flows through twist according to Fleming's lefft-hand rule, this spirality electric current (guide current) that is induced interacts with the magnetic line of force can produce electromagnetic force (F), the action direction of this power is identical with the moving direction of magnet, and the rotation principle of Here it is motor also is known as " my ancient disk ".
The rotation of the magnetic line of force on my the ancient disk at this moment is identical with the magnetic field that stator generated of motor, and disk (conductor) is identical with rotor, and actual motor designs must have also higher than this better revolving force and efficient.
The present invention utilizes this principle exactly, in the arranged outside guided rings (33) of permanent magnet rotor (32), makes also rotation thereupon of guided rings (33) by making rotor (32) rotation.
In addition, when output rod reset delay type gear motor of the present invention (1) is used as clutch motor, because take-off lever (5) can restore by the delay certain hour again when being connected the power supply off on the motor, even therefore having only agitator under the washing state of rotation, the phenomenon that the sawtooth breakage also can not appear causing because of the decline of carriage in instantaneous power failure to occur.
In when, promptly instantaneous power failure taking place, the decline of the carriage that causes because of the recovery of take-off lever (5) also has the delay of certain hour, that is to say because instantaneous power failure takes place at short notice and power supply can be connected at once, so the problem of the breakage of the sawtooth that causes owing to the decline and the rising of carriage when take-off lever (5) not have generation instantaneous power failure under the situation of time-delay in the prior art has just been solved.
In addition, take-off lever action delaying type gear motor of the present invention singly can not be applied on clutch and the door lock assembly, on the diversified device that need delay time when it can also be applied in action, in the category that does not break away from technical concept of the present invention, can make various deformation and modification certainly.
Particularly constitute the number of gear of gear string and the action time delay that the gear ratio of gear, the permanent magnet that change constitutes guided rings (33) and rotor (11) etc. can change take-off lever (5) easily by change.
The effect of invention:
As mentioned above, the present invention is by improving clutch or the draining valve that drives washing machine or pinning and wash The clothing machine when door used gear motor structure, postpone certain in the time of can disconnecting (off) at power supply After time the take-off lever of gear motor is initialised.
Can improve the reliable of action when therefore gear motor of the present invention (1) is applied on the door lock assembly Property and security.
Namely in the process that dehydration finishes or dehydration is carried out, suspend owing to user's operation or power failure etc. Former thereby when power supply on the motor is cut off, door lock do not opened at once but postpone certain hour it Back door lock (locking) thereby just be opened can be opened door, therefore can prevent effectively The security incident that the drench pit of owing to inertial rotation when door is opened causes.
In a word, the present invention can be because dehydration finishes or other is former thereby when making that off appears in motor in dehydration, a state that after postponing certain hour door is lockable is disengaged, so can guarantee user's safety.
In addition, when gear motor of the present invention (1) comes the time spent as clutch motor, even under the washing state, instantaneous power failure occurs,, therefore can avoid taking place the breakage of the sawtooth that the decline owing to carriage causes because the recovery of take-off lever (5) need postpone certain hour.
