[0002] The working modes of the pulsator washing machine include washing mode and dehydration mode. The dehydration mode is a working mode in which the pulsator shaft and the dehydration shaft are rigidly connected to the input power component, and the driving motor is used to drive the power input component to rotate, thereby driving the pulsator shaft and the dehydration shaft to rotate at the same speed.

[0003] In order to realize the rigid connection between the dehydration shaft and the input power component in the dehydration working mode, a clutch device is provided in the pulsator washing machine, and the clutch device includes a control mechanism and a clutch sleeve; after entering the dehydration working mode, the control mechanism drives the clutch sleeve to move axially toward the power input component side, so that the insert of the clutch sleeve and the insert in the power input component are engaged, and then the clutch sleeve is used to realize the rigid connection between the dehydration shaft and the power input component.

The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment"; the term "some embodiments" means "at least some embodiments".

It should be noted that the concepts of "first", "second", etc. mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the processes performed by these devices, modules or units.

[0038] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0039] The disclosed embodiment provides a control method for a pulsator washing machine, which performs special control when the pulsator washing machine enters a dehydration working mode so that the clutch sleeve and the insert on the power input component are engaged as correctly as possible, thereby allowing the dehydration operation to be performed as correctly as possible.

[0040] In order to better understand the control method of the pulsator washing machine provided by the embodiment of the present disclosure, the structure of the pulsator washing machine is briefly analyzed below. It should be noted that the structure of the pulsator washing machine described below is only a basic structure. In actual application, the structure of the pulsator washing machine is improved on the following structure to have more functions.

[0041] In the disclosed embodiment, the pulsator washing machine includes an outer tub, an inner tub, a pulsator, a driving motor, a power input component, a pulsator shaft, a dehydration shaft and a clutch device.

[0042] An inner tub rotatable relative to the outer tub is disposed in the outer tub, a pulsator rotatable relative to the inner tub in a washing mode is disposed in the inner tub, and the inner tub and the pulsator are coaxially disposed.

[0043] The power input component and the impeller shaft can be directly rigidly connected, and under the driving action of the driving motor, the power input component can always drive the impeller shaft to rotate.

[0044] The clutch device is used to rigidly connect the dehydration shaft with the power input component when the pulsator washing machine enters the dehydration working mode, so that the driving torque generated by the driving motor is at least partially transmitted to the dehydration shaft through the power input component and the clutch device. The dehydration shaft is rigidly connected to the inner tub. During the dehydration operation, the dehydration shaft can transmit the driving torque to the inner tub to rotate the inner tub.

[0045] The clutch device includes a control mechanism and a clutch sleeve. The clutch sleeve has a hollow tooth groove at the axis center, and the hollow tooth groove is engaged with the spline on the outside of the dehydration shaft. A first insert is provided at the end of the clutch sleeve facing the power input component. In addition, a second insert is provided at the end of the power input component facing the clutch sleeve. When the control mechanism controls the clutch sleeve to move toward the power input component and the first insert and the second insert are arranged in a misaligned manner, the first insert and the second insert can be engaged. In this way, the driving torque generated by the drive motor can be transmitted to the second insert of the clutch sleeve through the first insert of the power input component, and transmitted to the dehydration shaft through the tooth groove of the clutch sleeve and the spline on the outside of the dehydration shaft, so that the dehydration shaft drives the inner barrel to rotate to perform the dehydration operation.

[0046] The control mechanism can control the clutch sleeve to move axially. In a specific application, the control mechanism includes a tractor and a spring. The spring is arranged between the dehydration shaft and the clutch sleeve, and the elastic force generated by the spring makes the clutch sleeve have a tendency to approach the power input component, so that the first insert and the second insert are engaged. The tractor is used to apply a force to the clutch sleeve so that the clutch sleeve has a tendency to move away from the power input component. When the tractor is in the first working state, the force of the tractor acting on the clutch sleeve in the axial direction is greater than the force of the spring acting on the clutch sleeve, the first insert on the clutch sleeve and the second insert of the power input component are disengaged, and the drive motor cannot drive the dehydration shaft to rotate; when the tractor is in the second working state, the force of the tractor acting on the clutch sleeve in the axial direction is less than the force of the spring acting on the clutch sleeve, and the clutch sleeve moves toward the power input component side.

[0047] As described in the background technology, in order to ensure working reliability, the first insert on the clutch sleeve and the second insert on the power input component are mostly wedge-shaped inserts. When the clutch sleeve moves toward the power input component, the first insert and the second insert may be misaligned so that the two can fit together, or the first insert and the second insert may be arranged opposite to each other so that the two are pressed against each other and are not properly fitted together.

[0048] The control method of the pulsator washing machine provided in the embodiment of the present disclosure is to solve the problem that when the clutch sleeve moves toward the power input component side, the first block and the second block are arranged opposite to each other and are pressed against each other, and cannot be properly engaged, resulting in the inability to perform the dehydration operation normally.

[0049] Figure 1 1 is a flow chart of a control method for a pulsator washing machine provided by an embodiment of the present disclosure. Figure 1 As shown, the control method of the pulsator washing machine provided by the embodiment of the present disclosure includes S110-S120. The control method of the pulsator washing machine provided by the embodiment of the present disclosure is executed by a controller in the pulsator washing machine.

[0050] S110: Determine that the pulsator washing machine enters the dehydration working mode, and perform pre-power-on and power-off operations on the driving motor.

[0051] In the disclosed embodiment, the controller may determine whether the pulsator washing machine enters the dehydration working mode based on its control over the pulsator washing machine and the sensor detection signal.

[0052] In some working modes, before entering the dehydration working mode, the controller will control the pulsator washing machine to perform a drainage operation. During the drainage operation, the controller will receive a water level signal fed back by the water level sensor. After the water level signal determines that the pulsator washing machine has finished draining, the controller then controls the tractor to work, so that the tractor drives the clutch sleeve to move toward the power input component side, and when the tractor works for the first time, it is determined that the pulsator washing machine enters the dehydration working mode.

[0053] After determining that the pulsator washing machine enters the dehydration operation mode, the controller controls the driving motor to perform pre-on and off operations.

[0054] The pre-power-on and power-off operation of the drive motor is to power the drive motor for a very short time and then immediately control the drive motor to power off. By quickly powering the drive motor on and off, the drive motor can continuously output the drive torque during a short power-on time. Because the power-on time is very short, the drive torque output during the power-on time will not cause the power input component connected to the drive motor to rotate continuously, but can only cause a small movement of the power input component, that is, the power input component rotates a small angle.

[0055] In the embodiment of the present disclosure, the controller controls the pre-power-on and power-off operation of the drive motor according to the pre-set power-on and power-off control strategy, so that the driving torque generated by the drive motor during each power-on and power-off operation can only make the rotation arc of the power input component less than or equal to the arc of the target block, that is, the maximum rotation arc of the second block relative to the first block is less than the arc of the target block. The aforementioned target block is the block with a larger arc between the first block and the second block that can be mutually engaged during the dehydration operation.

[0056] Since the driving torque generated by the driving motor during each power-on and power-off operation makes the rotation arc of the power input component (that is, the second block) smaller than the arc of the target block, if the first block and the second block are in a state of being pressed against each other, then after a single power-on and power-off operation of the power input component, the relative position change between the first block and the second block may occur in two situations: the first situation: under the action of the driving torque, the second block moves relative to the first block, so that the pressing contact position of the two blocks changes, but the first block and the second block are still in a state of being pressed against each other; the second situation: under the action of the driving torque, the second block moves relative to the first block, so that the pressing contact position of the two blocks changes, and the two blocks are misaligned at a certain point in time and no longer press against each other. At this time, under the action of the axial force provided by the control mechanism, the first block and the second block are interlocked with each other.

[0057] In a specific implementation, the probability of the relative position change between the first block and the second block occurring in the first situation or the second situation each time the power is turned on and off is related to the magnitude of the rotation arc of the power input component caused by the driving torque generated by the driving motor each time the power is turned on and off. If the driving torque generated by the driving motor causes the rotation arc of the power input component to be equal to the arc of the target block, the probability of the second situation occurring is extremely high, which is substantially 1. If the driving torque generated by the driving motor causes the rotation arc of the power input component to be smaller than the arc of the target block, the smaller the rotation arc, the greater the probability of the first situation occurring, and the smaller the probability of the second situation occurring.

[0058] According to the above analysis, the ideal state is that the driving torque generated by the driving motor during the power on and off operation makes the rotation arc of the power component relative to the clutch sleeve equal to the arc of the target block, and then only the second situation mentioned above occurs. However, due to the limitations of conditions such as the workpiece processing quality, the assembly error of the pulsator washing machine and the control error of the driving motor, the driving torque generated by the driving motor during the power on and off operation makes the rotation arc of the power component relative to the clutch sleeve equal to the arc of the target block. This is only a theoretical situation and cannot be achieved in practical applications.

[0059] Accordingly, in actual applications, the driving torque generated by the driving motor during each pre-power-on and power-off operation makes the rotation arc of the power input component relative to the clutch sleeve smaller than the arc of the target block. In this case, the probability of the first situation becoming greater, and the smaller the rotation arc, the greater the probability of the first situation. In order to solve this problem, in some embodiments, the controller controls the driving motor to perform at least two pre-power-on and power-off operations, so as to utilize at least two pre-power-on and power-off operations to make the first block and the second block move relative to each other at least twice, thereby increasing the probability of the second situation. In a specific implementation, the smaller the value of the rotation arc of the power input component caused by the driving torque, the larger the number of pre-power-on and power-off operations should be set accordingly.

[0060] In a specific implementation, by reasonably setting the rotation arc of the power input component for each power on and off operation, the second situation will inevitably occur after at least two pre-power on and off operations. For example, if the rotation arc of the power input component during each power on and off operation is 0.55 times the arc of the target block, the probability that the first block and the second block are interlocked after two pre-power on and off operations is very high. For another example, if the rotation arc of the power input component during each power on and off operation is 0.2 times the arc of the target block, the probability that the first block and the second block are interlocked after six power on and off operations on the first block is very high.

[0061] According to the above analysis, by pre-powering on and off the driving motor, the first block and the second block are most likely already engaged. Then, the pulsator washing machine can enter the dehydration operation.

[0062] S120: Determine that the pre-power-on and power-off operations on the drive motor are completed, and perform a dehydration power-on operation on the drive motor.

[0063] In the embodiment of the present disclosure, the controller can determine the end of the pre-power-on / off operation of the drive motor by a timing method. Assuming that the execution cycle of a pre-power-on / off operation is 0.03s, and the number of pre-power-on / off operations is preset to 10 times, the controller determines that the pre-power-on / off operation of the drive motor is ended 0.3s after starting the pre-power-on / off operation of the drive motor.

[0064] After determining that the pre-power-on and power-off operations on the drive motor are completed, the controller then controls the drive motor to perform a dehydration power-on operation, so that the drive motor continues to rotate at a high speed, and drives the inner barrel to rotate through the power input component, clutch sleeve, and dehydration shaft to achieve the dehydration operation.

[0065] In some embodiments, the controller controls the drive motor to perform a dehydration power-on operation, which may be to keep the drive motor powered on for a period of time, and then the drive motor drives the inner drum of the pulsator washing machine to rotate. In other embodiments, the controller controls the drive motor to perform a dehydration power-on operation, which may be to keep the drive motor powered on intermittently, and then the drive motor drives the inner drum of the pulsator washing machine to rotate intermittently.

[0066] The control method of the pulsator washing machine provided by the embodiment of the present disclosure is that after the pulsator washing machine enters the dehydration working mode, the driving motor is pre-powered on and off, so that the second block in the power input component moves relative to the first block on the clutch sleeve, thereby increasing the probability of the first block and the second block being engaged. After determining that the pre-powered on and off operation of the driving motor is completed, the driving motor is powered on for dehydration, so that the driving motor drives the pulsator washing machine to perform the dehydration operation.

[0067] By adopting the control method of the pulsator washing machine provided by the embodiment of the present disclosure, the first insert of the clutch sleeve and the second insert on the power input component can be properly engaged as much as possible by pre-powering on and off the driving motor, so that the dehydration operation can be performed as correctly as possible, reducing the situation where the dehydration operation cannot be performed normally. In addition, the method implemented by the present disclosure can also reduce the abnormal noise generated when the pulsator washing machine cannot perform the dehydration operation normally.

[0068] As analyzed above, in actual applications, the drive motor is usually pre-powered on and off for at least two times, so that the first insert on the clutch sleeve and the second insert on the power input component can be correctly engaged. In this case, if the number of pre-power-on and power-off operations is reasonably determined, it is very important to ensure that the first insert and the second insert are correctly engaged and to avoid functional degradation of the structural parts caused by excessive movement operations. The following is an analysis of how to determine the number of quick power-on operations.

[0069] In some embodiments of the present disclosure, the power input component is a pulley, and the driving motor drives the power input component to rotate by means of belt transmission. According to the characteristics of belt transmission, as the number of times and the usage time of the pulsator washing machine increase, the belt will gradually stretch, and the belt will also drive the output pulley of the motor and the power input component to slip, causing the torque transmission efficiency to decrease. In other words, as the number of times the pulsator washing machine is operated increases, the driving torque generated by the driving motor during a single power-on and power-off operation causes the rotation arc of the power input component relative to the clutch sleeve to gradually decrease. According to the above analysis, if the rotation arc of the power input component relative to the clutch sleeve decreases, in order to ensure that the probability of the first insert and the second insert engaging increases, the number of pre-power-on and power-off operations needs to be increased accordingly.

[0070] Figure 2 1 is a flow chart of a control method for a pulsator washing machine provided by some other embodiments of the present disclosure. Figure 2 As shown, in some other embodiments of the present disclosure, the control method of the pulsator washing machine includes S210-S240.

[0071] S210: Determine whether the pulsator washing machine enters the dehydration working mode, and obtain the number of times and / or the running time of the pulsator washing machine.

[0072] In the disclosed embodiment, the running times of the pulsator washing machine refers to the number of times the driving motor drives the power input component to rotate continuously, and the running time refers to the time the driving motor drives the power input component to rotate continuously. The pulsator washing machine is equipped with a memory, which can store the running times and / or running time of the pulsator washing machine. The controller can determine the running times and / or running time by reading the data stored in the memory.

[0073] S220: Determine the number of pre-power-on and power-off operations based on the number of operations and / or the operation time.

[0074] According to the above analysis, as the number of operations and the running time increase, the driving torque generated by the driving motor causes the rotation arc of the power input component relative to the clutch sleeve to gradually decrease, and the number of pre-power-on and power-off operations needs to be increased accordingly. In other words, the number of quick power-on and power-off operations is proportional to the number of operations and the running time of the pulsator washing machine.

[0075] Correspondingly, the weighted coefficient can be multiplied by the aforementioned number of operations and / or the running time to obtain a value, and the aforementioned value is used as the number of pre-power-on and power-off operations. How to determine the number of pre-power-on and power-off operations will be analyzed in detail later. However, the general idea is to multiply the weighted coefficient by the number of operations and / or the running time.

[0076] S230: Determine that the pulsator washing machine enters the dehydration mode, and perform pre-on and off operations on the driving motor.

[0077] S240: Determine that the pre-power-on and power-off operations on the drive motor are completed, and perform a dehydration power-on operation on the drive motor.

[0078] The contents of S230-S240 are the same as those of S110-S2120 in the previous text, and will not be repeated here. For details, please refer to the previous text.

[0079] In the disclosed embodiments, in combination with the characteristic that most pulsator washing machines use belt transmission to transmit driving torque to realize the rotation of the power input component, the number of pre-power-on and power-off operations is determined according to the number of times the pulsator washing machine has been run and / or the running time, and the drive motor is pre-powered on and off based on the number of pre-power-on and power-off operations. This can overcome the problem that a fixed number of pre-power-on and power-off operations cannot ensure that the first block and the second block will be engaged after moving with each other due to problems such as aging of the washing machine belt.

[0080] As analyzed above, the general idea of ​​determining the number of pre-power-on and power-off operations based on the number of operations and / or the running time is to multiply the weighted coefficient by the number of operations and / or the running time to obtain the number of pre-power-on and power-off operations. However, it should be noted that when the pulsator washing machine is just used, the first block and the second block are pressed tightly and cannot be dehydrated normally. In this case, the number of operations and the running time of the pulsator washing machine are very small, and the number of pre-power-on and power-off operations obtained by multiplying them by the weighted coefficient is very small, and it is impossible to ensure that the first block and the second block are likely to fit together. In order to solve this problem, S250 can also be executed before executing the aforementioned S220.

[0081] S250: Determine the basic number of times.

[0082] The basic number of times is a pre-set number of pre-power-on and power-off operations that are performed at least when the pulsator washing machine enters the dehydration working mode. In some cases, such as when the pulsator washing machine has just been used, the basic number of times is the number of pre-power-on and power-off operations performed on the drive motor. According to the analysis in the previous article, the basic number of times is set according to the driving torque generated by the drive motor during a single pre-power-on and power-off operation when the pulsator washing machine is just used, which makes the rotation arc of the input component relative to the clutch sleeve. The larger the rotation arc, the smaller the basic number of times can be set. However, it should be noted that the basic number of times is at least 1 time.

[0083] In the case of executing the aforementioned S250, the aforementioned S220 may include S221.

[0084] S221: Determine the number of pre-power-on and power-off operations based on the basic number, the number of operations completed and / or the operation time completed.

[0085] The following describes how to determine the number of pre-on / off operations based on the basic number, the number of operations performed, and / or the time of operation. Determine the number of pre-power-on and power-off operations, where m is the number of pre-power-on and power-off operations, n is the basic number, k is the set weighted weight, and p is the number of operations. Based on the above formula, the number of pre-power-on and power-off operations on the drive motor is at least n times. As the number of times the pulsator washing machine has been operated increases, the number of pre-power-on and power-off operations will gradually increase.

[0086] In some other embodiments, the controller uses Determine the number of pre-power-on and power-off operations, where k1 is the weight of the number of times the pulsator washing machine has run, k2 is the weight of the time the pulsator washing machine has run, and q is the time the pulsator washing machine has run.

[0087] In some further embodiments, the controller uses The number of pre-power-on and power-off operations is determined, where k3 is the weight of the running time of the pulsator washing machine.

[0088] Of course, in other implementations, other methods may be used to determine the number of pre-power-on and power-off operations, which will not be given as examples here.

[0089] In the foregoing embodiments, considering that the pulsator washing machine uses a belt drive to drive the power input component to rotate, in other embodiments, the pulsator washing machine may also use a chain drive, a gear drive or a direct drive to drive the power input component to rotate. In this case, there is no serious problem of reduced transmission efficiency as in belt drive. In this case, a basic number of times may also be set. When the pulsator washing machine enters the dehydration working mode, the drive motor is pre-powered on and off according to the basic number of times.

[0090] The foregoing is only a simple explanation of the pre-power-on and power-off operation. In actual applications, the pre-power-on and power-off operation of the drive motor may specifically include: quickly powering on the drive motor for a second time and then powering off for a third time. In the specific implementation, the aforementioned second time and third time are both relatively short times, which are on the order of ms. In the specific implementation, according to the input power of the drive motor and the mechanical transmission efficiency between the drive motor and the power input component, the second time can be set between 15-25ms, and the third time can be set between 3-7ms. For example, in a specific model, when the drive power of the drive motor is 150W, the second time can be set to 20ms, and the third time can be set to 5ms.
