It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details.

Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0051] The present application provides a driving assembly, which is applied to a clothing processing device, which may be a washing machine, a shoe washing machine, a clothes dryer, a washer-dryer or other device for clothing processing. Figure 1-Figure 2 , Figure 1 This is a schematic diagram of the structure of a clothes processing device provided in an embodiment of the present application. Figure 2A schematic diagram of the structure of a drive assembly provided in an embodiment of the present application, Figure 3 for Figure 1 The laundry processing device 10 is a cross-sectional view along the AA direction. The laundry processing device 10 includes an inner tub 100 and a driving assembly 200 . The driving assembly 200 includes a power unit 210 , a transmission assembly 220 and a first adjustment assembly 230 .

[0052] Among them, the transmission assembly 220 is used for transmission connection with the power unit 210 and the inner barrel 100. The power unit 210 drives the inner barrel 100 to rotate through the transmission assembly 220. The transmission assembly 220 includes a first transmission wheel 221 and a first transmission belt 222 connected to each other. The first transmission wheel 221 includes a first annular portion 2211 and a second annular portion 2212 arranged coaxially. A first annular belt groove 2213 suitable for assembling the first transmission belt 222 is formed between the first annular portion 2211 and the second annular portion 2212. The width of the first annular belt groove 2213 gradually increases toward the outer peripheral direction of the first transmission wheel 221; the first adjustment assembly 230 is connected to the first transmission wheel 221, and is used to drive the first annular portion 2211 and the second annular portion 2212 to move relative to each other to adjust the width of the first annular belt groove 2213, so as to adjust the transmission ratio of the first transmission belt 222.

[0053] It should be noted that a clothes processing chamber is formed inside the inner barrel 100, which is suitable for holding clothes. The inner barrel 100 may include a barrel body and a rotating shaft fixedly connected to the bottom of the barrel body. The transmission assembly 220 is used to connect with the rotating shaft of the inner barrel 100, and the rotating shaft of the inner barrel 100 is driven to rotate by the transmission assembly 220 to drive the barrel body to rotate, so as to realize the processing of clothes in the barrel body. Among them, the power unit 210 is, for example, a motor.

[0054] The width of the first annular belt groove 2213 gradually increases toward the outer circumference of the first transmission wheel 221, that is, the width of the first annular belt groove 2213 gradually increases from the inner ring toward the outer ring of the first transmission wheel 221. It can be understood that the first transmission belt 222 is assembled in the outward-expanding first annular belt groove 2213. By adjusting the width of the first annular belt groove 2213, the assembly depth of the first transmission belt 222 in the first annular belt groove 2213 can be adjusted to adjust the transmission ratio of the transmission belt, thereby achieving the rotation speed adjustment of the inner barrel 100. When the width of the first annular belt groove 2213 is increased, the groove wall distance of the first annular belt groove 2213 increases. Since the first annular belt groove 2213 is an outward expansion structure, the first transmission belt 222 moves toward the direction close to the rotation axis of the first transmission wheel 221 to reduce the rotation diameter of the first transmission belt 222 at one end close to the first transmission wheel 221; at this time, if the first transmission wheel 221 is a driving wheel, the transmission ratio of the first transmission belt 222 is reduced, and if the first transmission wheel 221 is a driven wheel, the transmission ratio of the first transmission belt 222 is increased. When the width of the first annular belt groove 2213 is reduced, the groove wall distance of the first annular belt groove 2213 is reduced. Since the first annular belt groove 2213 is an outward expansion structure, the first transmission belt 222 moves in a direction away from the rotation axis of the first transmission wheel 221 to increase the rotation diameter of the first transmission belt 222 at one end close to the first transmission wheel 221; at this time, if the first transmission wheel 221 is a driving wheel, the transmission ratio of the first transmission belt 222 is increased, and if the first transmission wheel 221 is a driven wheel, the transmission ratio of the first transmission belt 222 is reduced.

[0055] The driving component 200 of the inner barrel 100 provided in the embodiment of the present application can adjust the width of the first annular belt groove 2213 through the first adjustment component 230, so that the first transmission wheel 221 can move in the first annular belt groove 2213 in a direction away from or close to the rotation axis of the first transmission wheel 221, so as to adjust the transmission ratio of the first transmission belt 222, thereby realizing the speed adjustment of the inner barrel 100, so that the speed of the drum can actually reach the target speed, and eliminate the speed difference caused by the difference in the physical properties of the transmission belt caused by process fluctuations between the various clothing processing devices 10.

[0056] Further, such as Figure 3As shown, the first adjustment assembly 230 may include a first magnetic member 231, a first electromagnetic device 232 and a first elastic member 233. The first magnetic member 231 is connected to the second annular portion 2212; the first electromagnetic device 232 is suitable for generating a magnetic field to apply an electromagnetic force to the first magnetic member 231; one end of the first elastic member 233 is fixed, and the other end is connected to the second annular portion 2212, and is suitable for applying an elastic force opposite to the electromagnetic force to the second annular portion 2212, so that the second annular portion 2212 remains stationary when reaching a preset position; wherein the intensity of the magnetic field generated by the first electromagnetic device 232 is adjustable, so as to drive the second annular portion 2212 to move relative to the first annular portion 2211 through the first magnetic member 231.

[0057] Among them, the first magnetic member 231 can be a permanent magnet, or an electromagnet or other device, and no specific restrictions are made here. The first electromagnetic device 232 is a device that generates a magnetic field when powered on, and can be an electromagnet, an electromagnetic relay or other device. The first elastic member 233 can be a spring or other elastic device. It should be noted that the first electromagnetic device 232 generates a magnetic field when powered on, and the magnetic field can generate an electromagnetic force on the first magnetic member 231, so as to apply a pulling force or a thrust force in the axial direction to the second annular portion 2212 through the first magnetic member 231; the first elastic member 233 can apply a force opposite to the electromagnetic force to the second annular portion 2212, so that the second annular portion 2212 remains stationary when it moves to a preset position.

[0058] In actual application, when the intensity of the magnetic field generated by the first electromagnetic device 232 changes, the magnitude of the electromagnetic force generated by the magnetic field on the first magnetic component 231 changes, so that the first magnetic component 231 drives the second annular portion 2212 to move axially relative to the first annular portion 2211, and the second annular portion 2212 compresses or stretches the first elastic component 233 until it moves to the target position, so that the elastic force applied by the first elastic component 233 to the second annular portion 2212 and the electromagnetic force applied by the magnetic field to the first magnetic component 231 reach a balance, so that the second annular portion 2212 stops moving. In this way, by adjusting the position of the second annular portion 2212 relative to the first annular portion 2211, the width of the first annular groove 2213 can be adjusted.

[0059] Preferably, the first magnetic member 231 includes an annular permanent magnet 2311, and the annular permanent magnet 2311 is coaxially arranged with the second annular portion 2212. Optionally, the first electromagnetic device 232 includes an electromagnetic coil 2321 arranged opposite to the annular permanent magnet 2311, and the axial direction of the electromagnetic coil 2321 is parallel to the axial direction of the annular permanent magnet 2311. Figure 4 As shown, Figure 4A schematic diagram of the structure of the electromagnetic coil and the annular permanent magnet provided in an embodiment of the present application. There are multiple electromagnetic coils 2321, and the multiple electromagnetic coils 2321 are arranged in sequence along the circumferential direction of the central axis of the annular permanent magnet 2311, and the spacing between each two adjacent electromagnetic coils 2321 is the same. In this way, it is beneficial for the first electromagnetic device 232 to apply a uniform pulling force or thrust to the second annular portion 2212 through the annular permanent magnet 2311, ensuring that the second annular portion 2212 will not get stuck during movement.

[0060] In some embodiments, Figure 3 As shown, the first adjustment assembly 230 further includes a stopper 234, which is arranged opposite to the second annular portion 2212 and is located on the opposite side of the second annular portion 2212 as the first annular portion 2211. One end of the first elastic member 233 is fixedly connected to the stopper 234, and the other end is connected to the second annular portion 2212. The transmission assembly 220 further includes a transmission shaft 224, the first annular portion 2211 is fixedly sleeved on the transmission shaft 224, and the second annular portion 2212 is axially slidably sleeved on the transmission shaft 224. The stopper 234 is fixedly mounted on one end of the transmission shaft 224 close to the second annular portion 2212, for example, by a connecting member such as a screw, and the first elastic member 233 is a spring, which is sleeved on the transmission shaft 224 and arranged between the second annular portion 2212 and the stopper 234.

[0061] In some embodiments, the transmission shaft 224 is installed in the housing of the laundry processing device 10 through a fixing bracket 235. The fixing bracket 235 is, for example, fixedly installed in the housing of the laundry processing device 10 and sleeved on the outer periphery of the transmission shaft 224, and the fixing bracket 235 is connected to the transmission shaft 224 through a bearing. Optionally, the first electromagnetic device 232 is installed on the fixing bracket 235.

[0062] Exemplarily, the first annular portion 2211 includes a first side wall disposed toward the second annular portion 2212, the second annular portion 2212 includes a second side wall disposed toward the first annular portion 2211, and a first annular belt groove 2213 is formed between the first side wall and the second side wall; the first side wall is inclined toward the direction away from the second annular portion 2212 from the inner ring of the first transmission wheel 221 toward the outer ring; and / or the second side wall is inclined toward the direction away from the first annular portion 2211 from the inner ring of the first transmission wheel 221 toward the outer ring. In this way, a first annular belt groove 2213 with an outward expansion structure is formed between the first annular portion 2211 and the second annular portion 2212. Preferably, the first transmission belt 222 includes an outer wall surface suitable for matching with the side wall of the first annular belt groove 2213, and a concave-convex structure is provided on the outer wall surface. In this way, the first transmission belt 222 can be prevented from sliding and dislocating in the first annular belt groove 2213, thereby improving the structural stability of the transmission assembly 220.

[0063] In some embodiments, the transmission assembly 220 further includes a second transmission wheel 223, which is fixedly mounted on the output shaft of the power unit 210, and the second transmission wheel 223 is connected to the first transmission wheel 221 through the first transmission belt 222. In actual application, the power unit 210 drives the second transmission wheel 223 to rotate through the output shaft, and then the second transmission wheel 223 acts as a driving wheel, and drives the first transmission wheel 221, which acts as a driven wheel, to rotate through the first transmission belt 222. The first transmission wheel 221 is connected to the rotating shaft of the inner barrel 100, so that the inner barrel 100 is driven to rotate when the first transmission wheel 221 rotates. When the width of the first annular belt groove 2213 on the first transmission wheel 221 is increased, the transmission ratio of the first transmission belt 222 increases, so that the rotation speed of the inner barrel 100 increases; when the width of the first annular belt groove 2213 on the first transmission wheel 221 is reduced, the transmission ratio of the first transmission belt 222 decreases, so that the rotation speed of the inner barrel 100 decreases.

[0064] Optionally, see Figure 5 , Figure 5 for Figure 1 The cross-sectional view of the laundry processing device shown is taken along the BB direction. The second transmission wheel 223 includes a third annular portion 2231 and a fourth annular portion 2232 which are coaxially arranged, and a second annular belt groove 2233 suitable for assembling the first transmission belt 222 is formed between the third annular portion 2231 and the fourth annular portion 2232, and the width of the second annular belt groove 2233 gradually increases toward the outer circumference of the second transmission wheel 223; the driving assembly 200 also includes a second adjustment assembly 240, which is connected to the third annular portion 2231 and is used to drive the third annular portion 2231 and the fourth annular portion 2232 to move relative to each other to adjust the width of the second annular belt groove 2233, so as to adjust the transmission ratio of the first transmission belt 222.

[0065] It can be understood that one end of the first transmission belt 222 is assembled in the first annular belt groove 2213 on the first transmission wheel 221, and the other end is assembled in the second annular belt groove 2233 on the second transmission wheel 223; wherein, the widths of the first annular belt groove 2213 and the second annular belt groove 2233 are both adjustable, and the width of the first annular belt groove 2213 is adjusted by the first adjustment component 230, and / or the width of the second annular belt groove 2233 is adjusted by the second adjustment component 240, so as to adjust the transmission ratio of the first transmission belt 222, and then adjust the rotation speed of the inner barrel 100. In this way, the value range of the transmission ratio of the first transmission belt 222 can be widened, and the adjustment range of the transmission ratio of the first transmission belt 222 can be increased.

[0066] For example, Figure 5As shown, the second adjustment assembly 240 includes a second magnetic member 241, a second electromagnetic device 242 and a second elastic member 243. The second magnetic member 241 is connected to the third annular portion 2231; the second electromagnetic device 242 is suitable for generating a magnetic field to apply an electromagnetic force to the second magnetic member 241; one end of the second elastic member 243 is fixed, and the other end is connected to the third annular portion 2231, and is suitable for applying an elastic force opposite to the electromagnetic force to the third annular portion 2231, so that the third annular portion 2231 remains stationary when reaching a preset position; wherein the intensity of the magnetic field generated by the second electromagnetic device 242 is adjustable, so as to drive the third annular portion 2231 to move relative to the fourth annular portion 2232 through the second magnetic member 241.

[0067] Among them, the second magnetic member 241 can be a permanent magnet, or an electromagnet or other device, and no specific restrictions are made here. The second electromagnetic device 242 is a device that generates a magnetic field when powered on, and can be an electromagnet, an electromagnetic relay or other device. The second elastic member 243 can be a spring or other elastic device. It should be noted that the second electromagnetic device 242 generates a magnetic field when powered on, and the magnetic field can generate an electromagnetic force on the second magnetic member 241, so as to apply a pulling force or a thrust force in the axial direction to the third annular portion 2231 through the second magnetic member 241; the second elastic member 243 can apply a force opposite to the electromagnetic force to the third annular portion 2231, so that the third annular portion 2231 remains stationary when it moves to a preset position.

[0068] In actual application, when the intensity of the magnetic field generated by the second electromagnetic device 242 changes, the magnitude of the electromagnetic force generated by the magnetic field on the second magnetic component 241 changes, so that the second magnetic component 241 drives the third annular portion 2231 to move axially relative to the fourth annular portion 2232, and the third annular portion 2231 compresses or stretches the second elastic component 243 until it moves to the target position, so that the elastic force applied by the second elastic component 243 to the third annular portion 2231 and the electromagnetic force applied by the magnetic field to the second magnetic component 241 reach a balance, so that the third annular portion 2231 stops moving. In this way, by adjusting the position of the third annular portion 2231 relative to the fourth annular portion 2232, the width of the second annular belt groove 2233 can be adjusted.

[0069] The specific structure of the second adjustment component 240 may refer to the structure of the first adjustment component 230 , which will not be described in detail here.

[0070] In some embodiments, Figure 1-Figure 3As shown, the transmission assembly 220 further includes a third transmission wheel 225, a fourth transmission wheel 226 and a second transmission belt 227. The third transmission wheel 225 is fixedly sleeved on the transmission shaft 224, and the fourth transmission wheel 226 is used to be fixedly installed on the rotating shaft of the inner barrel 100, and the fourth transmission wheel 226 is connected to the third transmission wheel 225 through the second transmission belt 227. In actual application, the power unit 210 drives the second transmission wheel 223 to rotate through the output shaft, and then the second transmission wheel 223 drives the first transmission wheel 221 to rotate through the first transmission belt 222; since the first transmission wheel 221 and the third transmission wheel 225 are both installed on the transmission shaft 224, when the first transmission wheel 221 rotates, the third transmission wheel 225 is driven to rotate through the transmission shaft 224, and then the third transmission wheel 225 drives the fourth transmission wheel 226 to rotate through the second transmission belt 227, so that the fourth transmission wheel 226 drives the inner barrel 100 to rotate.

[0071] Optionally, the belt grooves on the third transmission wheel 225 and / or the fourth transmission wheel 226 can also be set as an outward-expanding structure with adjustable width to achieve adjustable transmission ratio of the second transmission belt 227. The specific structure can refer to the above-mentioned first transmission wheel 221 and second transmission wheel 223, and will not be repeated here.

[0072] The driving component 200 of the inner barrel 100 provided in the embodiment of the present application can adjust the width of the first annular belt groove 2213 through the first adjustment component 230, so that the first transmission wheel 221 can move in the first annular belt groove 2213 in a direction away from or close to the rotation axis of the first transmission wheel 221, so as to adjust the transmission ratio of the first transmission belt 222, thereby realizing the speed adjustment of the inner barrel 100, so that the speed of the drum can actually reach the target speed, and eliminate the speed difference caused by the difference in the physical properties of the transmission belt caused by process fluctuations between the various clothing processing devices 10.

[0073] The present application also provides a clothes processing device, see Figure 1-Figure 3 The laundry processing device 10 includes an inner tub 100 and a driving assembly 200 in any of the above embodiments. The driving assembly 200 is connected to the inner tub 100 and is used to drive the inner tub 100 to rotate.

[0074] In some embodiments, the laundry processing device 10 further includes a rotation speed detection device 300, which is used to detect the rotation speed of the inner barrel 100. The controller of the laundry processing device 10 can obtain the rotation speed of the inner barrel 100 through the rotation speed detection device 300, and control the first adjustment component 230 to adjust the transmission ratio of the first transmission belt 222 according to the rotation speed of the inner barrel 100, so as to adjust the rotation speed of the inner barrel 100, so that the rotation speed of the drum can actually reach the target rotation speed. The rotation speed detection device 300 can be a capacitive / inductive rotation speed sensor, an optical fiber sensor, a Hall sensor, or other devices that can detect the actual rotation speed of the inner barrel.

[0075] The clothing processing device 10 provided in the embodiment of the present application has a driving component 200 of the inner barrel 100, which adjusts the width of the first annular belt groove 2213 through the first adjustment component 230, so that the first transmission wheel 221 can move in the first annular belt groove 2213 in a direction away from or close to the rotation axis of the first transmission wheel 221, so as to adjust the transmission ratio of the first transmission belt 222, thereby realizing the speed adjustment of the inner barrel 100, so that the speed of the drum can actually reach the target speed, and eliminate the speed difference caused by the difference in the physical properties of the transmission belt caused by process fluctuations between the various clothing processing devices 10.

[0076] The present application also provides a control method, which is applied to the above-mentioned clothes processing device 10, see Figure 6 , Figure 6 This is a flow chart of a control method provided in an embodiment of the present application. The control method includes the following steps S101 to S103:

[0077] Step S101: Control the power unit 210 to drive the inner tub 100 to rotate based on a preset speed;

[0078] It should be noted that when the power unit 210 rotates at a preset speed, if the transmission ratio of the transmission assembly 220 is at a standard transmission ratio, the actual rotation speed of the inner barrel 100 can reach the set target rotation speed.

[0079] Step S102: obtaining the current rotation speed of the inner barrel 100;

[0080] Optionally, the laundry processing device 10 can be provided with a rotation speed sensor to detect the actual rotation speed of the inner tub 100. When the actual transmission ratio of the transmission assembly 220 differs from the standard rotation ratio, the measured current rotation speed of the inner tub 100 will also differ from the target rotation speed. If the inner tub 100 cannot reach the set target rotation speed, the laundry processing device 10 cannot achieve the desired laundry processing effect. On the contrary, if the measured current rotation speed is greater than or less than the target rotation speed, it means that the actual transmission ratio of the current transmission assembly 220 differs from the standard transmission ratio.

[0081] Step S103 : according to the current rotation speed, controlling the first adjustment assembly 230 to drive the first annular portion 2211 and the second annular portion 2212 to move relative to each other to adjust the width of the first annular belt groove 2213 , so as to adjust the transmission ratio of the first transmission belt 222 .

[0082] In this way, the first adjustment component 230 is controlled to adjust the transmission ratio of the first transmission belt 222. By adjusting the actual transmission ratio of the first transmission belt 222 to the standard transmission ratio, the actual rotation speed of the inner barrel 100 can reach the target rotation speed, thereby improving the clothing processing effect of the clothing processing device 10.

[0083] Regarding how to control the first adjustment component 230 to adjust the width of the first annular belt groove 2213 according to the current rotation speed, the present application provides an optional embodiment: according to the current rotation speed, controlling the first adjustment component 230 to drive the first annular portion 2211 and the second annular portion 2212 to move relative to each other to adjust the width of the first annular belt groove 2213 to adjust the transmission ratio of the first transmission belt 222 includes:

[0084] Calculate the speed difference between the current speed and the target speed;

[0085] The target width is calculated based on the speed difference;

[0086] The first adjustment assembly 230 is controlled to drive the first annular portion 2211 and the second annular portion 2212 to move relative to each other so as to adjust the width of the first annular groove 2213 to a target width.

[0087] When the width of the first annular belt groove 2213 is the target width, the transmission ratio of the first transmission belt 222 can reach the standard transmission ratio, so that the actual rotation speed of the inner barrel 100 can reach the target rotation speed.

[0088] Optionally, calculating the target width according to the rotation speed difference may include:

[0089] Acquire a processing model, where the processing model is trained based on a plurality of sets of sample data, where the sample data includes a sample rotation speed difference and a sample width corresponding to the sample rotation speed difference;

[0090] The calculated rotation speed difference is input into the processing model to obtain the corresponding target width.

[0091] It should be noted that the sample data can be obtained by the tester through testing. The data in the sample data should ensure accuracy, and the amount of data should be sufficient to ensure the calculation accuracy of the processing model. For example, N groups of sample collection experiments are conducted on several prototypes, and the speed difference of each group of experiments is n. i The speed test device measures the optimal width W corresponding to each speed difference i, so that N sets of sample data are obtained; among them, the speed difference between the actual speed of the inner barrel and the target speed is n i When the width of the first annular groove 2213 is adjusted to the optimal width W i , the actual speed of the inner barrel measured by the speed testing device is the target speed.

[0092] In some embodiments, before obtaining the processing model through sample data training, a series of preprocessing and data processing operations such as imbalance and category processing can be performed on the original sample data. On the one hand, this can prevent the classification model from failing to work due to data reasons. On the other hand, it can accelerate the training of the classification model, improve the accuracy of the algorithm, and improve the adaptability of the classification algorithm model to imbalanced data sets.

[0093] In some embodiments, see Figure 7 , Figure 7 Another flow chart of the control method provided in the embodiment of the present application. The control method includes the following steps S201-S206:

[0094] Step S201: Control the power unit 210 to drive the inner tub 100 to rotate based on a preset speed, and obtain the current speed of the inner tub 100;

[0095] Step S202: calculating the speed difference between the current speed of the inner tub 100 and the target speed;

[0096] Step S203: generating a corresponding control signal according to the rotation speed difference;

[0097] Step S204: adjusting the magnetic field strength of the first electromagnetic device 232 according to the control signal to drive the second annular portion 2212 to move to a preset position to adjust the width of the first annular groove 2213;

[0098] Step S205: determining whether the second annular portion 2212 actually moves to a preset position;

[0099] The actual position of the second annular portion 2212 can be detected by the position detection device, and then the processing unit of the laundry processing device 10 determines whether the second annular portion 2212 actually reaches the preset position by comparing the actual position with the preset position. If the second annular portion 2212 has actually moved to the preset position, it means that the width of the first annular belt groove 2213 has been adjusted to the target width, and then step S206 is entered, otherwise it returns to step S204.

[0100] Step S206: Adjustment is completed.

[0101] The control method provided in the embodiment of the present application detects the actual rotation speed of the inner barrel 100, and controls the first adjustment component 230 to adjust the width of the first annular belt groove 2213 according to the actual rotation speed, so that the inner barrel 100 can reach the target rotation speed, thereby improving the clothing processing effect of the clothing processing device 10.
