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.

[0053] The present application provides a bearing 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 1 This is a schematic diagram of the structure of a clothes processing device provided in an embodiment of the present application. Figure 2 for Figure 1 The laundry processing apparatus 10 is a cross-sectional view taken along the AA direction. The laundry processing apparatus 10 includes a drum 100 , a rotating shaft 200 and a bearing assembly 300 .

[0054] The rotating shaft 200 is fixedly installed at the bottom of the drum 100, and the rotating shaft 200 is suitable for being driven by the power device to drive the drum 100 to rotate. The bearing assembly 300 includes a bearing seat 310, a front bearing 320, a rear bearing 330 and an adjustment assembly 340. The bearing seat 310 is formed with a bearing installation cavity 311; the front bearing 320 and the rear bearing 330 are installed in the bearing installation cavity 311, which is suitable for the rotating shaft 200 to pass through; the adjustment assembly 340 includes a motion mechanism 341 and a driving mechanism 342, and the front bearing 320 and / or the rear bearing 330 can be relatively movably matched with the bearing seat 310 and the rotating shaft 200 through the motion mechanism 341, and the driving mechanism 342 is connected to the motion mechanism 341, which is suitable for driving the motion mechanism 341 to adjust the distance between the front bearing 320 and the rear bearing 330.

[0055] It should be noted that the rotating shaft 200 is inserted into the bearing mounting cavity 311, one end of the rotating shaft 200 is connected to the drum 100, and the other end is connected to the driving device of the clothing processing device 10, such as a motor. The bearing seat 310 is suitable for being fixed to the outer shell of the clothing processing device 10, and is used to support the rotating shaft 200 and reduce the friction when the rotating shaft 200 rotates, so that the rotating shaft 200 can rotate smoothly, and then the drum 100 can rotate smoothly. The bearing seat 310 is usually fixed to the frame of the washing machine by screws or other fixing methods. Optionally, a seal, such as a dust cover or a sealing ring, is also provided on the bearing seat 310 to prevent dust, moisture and other foreign matter from entering the bearing mounting cavity 311, thereby protecting the front bearing 320 and the rear bearing 330 from damage.

[0056] The front bearing 320 is sleeved on one end of the rotating shaft 200 close to the drum 100, and the rear bearing 330 is sleeved on one end of the rotating shaft 200 away from the drum 100. The front bearing 320 and the rear bearing 330 can be ball bearings, or other types of bearings such as oil-containing bearings, etc., which are not specifically limited here.

[0057] The bearing assembly 300 provided in the embodiment of the present application realizes that the distance between the front bearing 320 and the rear bearing 330 is adjustable by adding an adjustment assembly 340. In this way, when the load weight in the drum 100 changes, the span of the front and rear bearings 330 can be adjusted to balance the stress conditions of the front bearing 320 and the rear bearing 330 when the drum 100 rotates, thereby avoiding damage to the bearings due to excessively uneven stress, extending the service life of the clothing processing device 10, and bringing a better user experience to the user.

[0058] The front bearing 320 and / or the rear bearing 330 can cooperate with the bearing seat 310 and the rotating shaft 200 through the motion mechanism 341 so as to be relatively movable, indicating that there are the following three implementation modes: the first is that the front bearing 320 is fixedly connected to the rotating shaft 200 and the bearing seat 310, and the rear bearing 330 can cooperate with the bearing seat 310 and the rotating shaft 200 through the motion mechanism 341 so as to be relatively movable; the second is that the rear bearing 330 is fixedly connected to the rotating shaft 200 and the bearing seat 310, and the front bearing 320 can cooperate with the bearing seat 310 and the rotating shaft 200 through the motion mechanism 341 so as to be relatively movable; the third is that the front bearing 320 and the rear bearing 330 can cooperate with the bearing seat 310 and the rotating shaft 200 through the motion mechanism 341 respectively. The driving mechanism 342 drives the motion mechanism 341 so as to make the front bearing 320 and the rear bearing 330 move relative to each other, thereby adjusting the distance between the front bearing 320 and the rear bearing 330.

[0059] For example, Figure 1-Figure 2 As shown, the front bearing 320 is used to be fixedly connected with the rotating shaft 200 and the bearing seat 310, and the rear bearing 330 is relatively movable with the bearing seat 310 and the rotating shaft 200 through the motion mechanism 341; the driving mechanism 342 is suitable for driving the rear bearing 330 to approach or move away from the front bearing 320 through the motion mechanism 341. It can be understood that the relative position of the front bearing 320 in the bearing seat 310 is fixed, and the rear bearing 330 is driven to move in the bearing seat 310 so that the rear bearing 330 approaches or moves away from the front bearing 320, thereby adjusting the distance between the front bearing 320 and the rear bearing 330.

[0060] As for how the front bearing 320 and / or the rear bearing 330 can cooperate with the bearing seat 310 and the rotating shaft 200 for relative movement through the moving mechanism 341, the following implementation methods can be used: for example, the bearing is fixedly connected to the moving mechanism 341, and the moving mechanism 341 is connected to the bearing seat 310 and the rotating shaft 200 for relative movement, so that by driving the moving mechanism 341, the bearing can be driven to move relative to the bearing seat 310 and the rotating shaft 200; or, the moving mechanism 341 is fixedly or movably installed on the bearing seat 310 and the rotating shaft 200 as a transmission mechanism such as a gear / bar assembly, and the bearing is connected to the moving mechanism 341 for transmission, so that by driving the moving mechanism 341, the bearing can be driven to move relative to the bearing seat 310 and the rotating shaft 200; or, other implementation methods can also be used.

[0061] For example, see Figure 2-Figure 3 , Figure 3A schematic diagram of a structure in which a rear bearing provided in an embodiment of the present application is assembled to a bearing seat through a moving mechanism. The moving mechanism 341 includes a first moving member 3411 and a second moving member 3412. The first moving member 3411 is fixedly connected to the outer ring of the rear bearing 330 and is movably connected to the bearing seat 310; the second moving member 3412 is fixedly connected to the inner ring of the rear bearing 330 and is used to be movably connected to the rotating shaft 200; the driving mechanism 342 is suitable for driving the first moving member 3411 and / or the second moving member 3412 to move along the extension direction of the rotating shaft 200, so as to drive the rear bearing 330 to approach or move away from the front bearing 320.

[0062] It can be understood that the first moving member 3411 is fixedly connected to the outer ring of the rear bearing 330 and is movably connected to the bearing seat 310. The first moving member 3411 is driven by the driving mechanism 342 to drive the rear bearing 330 to move relative to the bearing seat 310. The second moving member 3412 is fixedly connected to the inner ring of the rear bearing 330 and is used to be movably connected to the rotating shaft 200. The second moving member 3412 is driven by the driving mechanism 342 to drive the rear bearing 330 to move relative to the rotating shaft 200.

[0063] The driving mechanism 342 is suitable for driving the first moving member 3411 and / or the second moving member 3412 to move along the extension direction of the rotating shaft 200, which means that there are the following three implementation modes: the first is that the driving mechanism 342 only drives the first moving member 3411 to move along the extension direction of the rotating shaft 200, and the second moving member 3412 can be driven by the first moving member 3411 to move along the extension direction of the rotating shaft 200; the second is that the driving mechanism 342 only drives the second moving member 3412 to move along the extension direction of the rotating shaft 200, and the first moving member 3411 can be driven by the second moving member 3412 to move along the extension direction of the rotating shaft 200; the third is that the driving mechanism 342 drives the first moving member 3411 and the second moving member 3412 at the same time, so that the first moving member 3411 and the second moving member 3412 move synchronously along the extension direction of the rotating shaft 200.

[0064] Optionally, the first moving part 3411 includes an outer ring bushing and balls, the outer ring bushing is fixedly mounted on the outer ring of the rear bearing 330, balls are installed on the outer peripheral side wall of the outer ring bushing, and the bushing is movably connected to the bearing seat 310 through the balls; and / or the second moving part 3412 includes an inner ring bushing and balls, the inner ring bushing is used to be mounted on the outer periphery of the rotating shaft 200, the inner ring of the rear bearing 330 is fixedly mounted on the outer periphery of the inner ring bushing, balls are installed on the inner peripheral side wall of the inner ring bushing, and the bushing is movably connected to the rotating shaft 200 through the balls.

[0065] The outer ring bushing and the inner ring bushing are both cylindrical, so that the structural stability and movement stability of the motion mechanism 341 can be improved. Further, a first guide rail is convexly provided on the outer peripheral side wall of the outer ring bushing, and the extension direction of the first guide rail is the same as the extension direction of the rotating shaft 200. The bearing seat 310 is correspondingly provided with a first guide groove matching the first guide rail, and the ball can be installed on the first guide rail. In addition, a second guide rail can be convexly provided on the inner peripheral side wall of the inner ring bushing, and the extension direction of the second guide rail is the same as the extension direction of the rotating shaft 200. The rotating shaft 200 is correspondingly provided with a second guide groove matching the second guide rail, and the ball can be installed on the second guide rail. In this way, the stability of the motion mechanism 341 along the extension direction of the rotating shaft 200 can be further improved. Preferably, there are multiple balls on the outer ring bushing and the inner ring bushing.

[0066] In some embodiments, a limiting portion 312 is further provided on the bearing seat 310, and the limiting portion 312 is suitable for cooperating with the motion mechanism 341 to limit the movement stroke of the front bearing 320 and / or the rear bearing 330. Exemplarily, an annular limiting groove is provided on the circumferential inner side wall of the bearing seat 310, and the first moving member 3411 is disposed in the annular limiting groove; the annular limiting groove includes two opposite side walls in the extension direction of the rotating shaft 200, and the two side walls block the two sides in the movement direction of the first moving member 3411 to limit the movement stroke of the first moving member 3411 in the extension direction of the rotating shaft 200, thereby limiting the movement stroke of the rear bearing 330. In this way, the structural stability of the assembly of the motion mechanism 341 and the bearing seat 310 can be improved.

[0067] As for the specific structure of the driving mechanism 342, the present application provides an implementation method, that is, the driving mechanism 342 includes a magnetic member 3421, an electromagnetic device 3422 and an elastic member 3423. The magnetic member 3421 is fixed on the motion mechanism 341; the electromagnetic device 3422 is installed on the bearing seat 310, and is suitable for generating a magnetic field to apply an electromagnetic force to the magnetic member 3421; the two ends of the elastic member 3423 are respectively fixedly connected to the motion mechanism 341 and the bearing seat 310, and the elastic member 3423 is suitable for applying an elastic force opposite to the electromagnetic force to the motion mechanism 341, so that the motion mechanism 341 remains stationary when reaching a preset position; wherein, the intensity of the magnetic field generated by the electromagnetic device 3422 is adjustable to drive the motion mechanism 341 to move.

[0068] Among them, the magnetic part 3421 can be a permanent magnet, or an electromagnet or other device, and no specific restrictions are made here. The electromagnetic device 3422 is a device that generates a magnetic field when powered on, and can be an electromagnet, an electromagnetic relay or other device. The elastic part 3423 can be a spring or other elastic device. It should be noted that the electromagnetic device 3422 generates a magnetic field when powered on, and the magnetic field can generate an electromagnetic force on the magnetic part 3421, so as to apply a pulling force or a thrust force in the extension direction of the rotating shaft 200 to the moving mechanism 341 through the magnetic part 3421; the elastic part 3423 can apply a force opposite to the electromagnetic force to the moving mechanism 341, so that the moving mechanism 341 remains stationary when reaching the preset position. In actual application, when the intensity of the magnetic field generated by the electromagnetic device 3422 changes, the magnitude of the electromagnetic force generated by the magnetic field on the magnetic part 3421 changes, so that the magnetic part 3421 drives the moving mechanism 341 to move along the extension direction of the rotating shaft 200 until it moves to the target position, so that the elastic force exerted by the elastic part 3423 reaches a balance with the electromagnetic force, and the moving mechanism 341 stops moving.

[0069] For example, Figure 2 As shown, the magnetic member 3421 is fixed on the inner ring bushing of the second moving member 3412, the electromagnetic device 3422 is installed on the bearing seat 310, and along the extension direction of the rotating shaft 200, the electromagnetic device 3422 is arranged on the side of the magnetic member 3421 away from the front bearing 320; one end of the elastic member 3423 is connected to the first moving member 3411, and the other end is connected to the bearing seat 310, and the extension direction of the elastic member 3423 is the same as the extension direction of the rotating shaft 200. Preferably, the electromagnetic device 3422 includes an electromagnetic coil, and the magnetic member 3421 is a permanent magnet. The permanent magnet and the electromagnetic coil are coaxially arranged, and the extension direction of the axis is the same as the extension direction of the rotating shaft 200. In this way, the stability of the moving mechanism 341 during movement can be improved.

[0070] In some embodiments, see Figure 4 , Figure 4 A partial structural schematic diagram of a bearing assembly provided in an embodiment of the present application. The bearing assembly 300 also includes a position detection device 343 suitable for detecting the position of the motion mechanism 341. The position detection device 343 can be installed on the bearing seat 310 and spaced apart from the electromagnetic device 3422. The position detection device 343 outputs a corresponding position signal, for example, by detecting changes in the surrounding magnetic field, so that the processor of the clothing processing device 10 determines the current position of the motion mechanism 341 according to the position signal, and then determines whether the motion mechanism 341 has actually reached the preset position; if it is determined that the motion mechanism 341 has not actually reached the actual position, the driving mechanism drives the motion mechanism again to adjust the distance between the front bearing and the rear bearing. In this way, the reliability of the operation of the adjustment component 340 can be improved.

[0071] The bearing assembly 300 provided in the embodiment of the present application realizes that the distance between the front bearing 320 and the rear bearing 330 is adjustable by adding an adjustment assembly 340. In this way, when the load weight in the drum 100 changes, the span of the front and rear bearings 330 can be adjusted to balance the stress conditions of the front bearing 320 and the rear bearing 330 when the drum 100 rotates, thereby avoiding damage to the bearings due to excessively uneven stress, extending the service life of the clothing processing device 10, and bringing a better user experience to the user.

[0072] The present application also provides a clothes processing device, see Figure 1-Figure 2 The laundry processing apparatus 10 includes a drum 100, a rotating shaft 200, a pulley 400 and a bearing assembly 300 in any one of the above embodiments.

[0073] The rotating shaft 200 is installed on the bearing assembly 300. Exemplarily, the rotating shaft 200 includes a first shaft section 210 and a second shaft section 220. The drum 100, the first shaft section 210, and the second shaft section 220 are connected in sequence. The diameter of the first shaft section 210 is greater than the diameter of the second shaft section 220. The first shaft section 210 is inserted into the front bearing 320, and the second shaft section 220 is inserted into the rear bearing 330. The end of the second shaft section 220 away from the first shaft section 210 also passes through the bearing seat 310 and is connected to the pulley 400. The pulley 400 is driven to rotate by the power device of the laundry processing device 10, so that the pulley 400 drives the drum 100 to rotate through the rotating shaft 200.

[0074] The clothing processing device 10 provided in the embodiment of the present application realizes that the distance between the front bearing 320 and the rear bearing 330 is adjustable by adding an adjustment component 340. In this way, when the load weight in the drum 100 changes, the span of the front and rear bearings 330 can be adjusted to balance the force conditions of the front bearing 320 and the rear bearing 330 when the drum 100 rotates, thereby avoiding damage to the bearings due to excessively uneven force, extending the service life of the clothing processing device 10, and bringing a better user experience to the user.

[0075] The present application also provides a control method, which is applied to the laundry processing device 10 in any of the above embodiments. Figure 5 , Figure 5 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-S102:

[0076] Step S101: obtaining the weight of the current load in the drum 100;

[0077] Optionally, the clothing processing device 10 may be provided with a pressure sensor to detect the weight information of the load, and may also calculate the weight of the load by adopting fuzzy weighing technology, image recognition technology or microwave recognition technology, which is not specifically limited here.

[0078] Step S102 : According to the weight, the driving mechanism 342 is controlled to drive the motion mechanism 341 to adjust the distance between the front bearing 320 and the rear bearing 330 .

[0079] In this way, when the load weight in the drum 100 changes, the span of the front and rear bearings 330 can be adjusted to balance the forces on the front bearing 320 and the rear bearing 330 when the drum 100 rotates, thereby avoiding damage to the bearings due to excessively uneven forces, extending the service life of the clothing processing device 10, and providing users with a better user experience.

[0080] Regarding how to control the driving mechanism 342 to drive the motion mechanism 341 according to the weight, the present application provides an optional embodiment: according to the weight, controlling the driving mechanism 342 to drive the motion mechanism 341 to adjust the distance between the front bearing 320 and the rear bearing 330 includes:

[0081] Obtaining a processing model, where the processing model is trained based on a number of groups of sample data, where the sample data includes sample weights and sample distances corresponding to the sample weights;

[0082] Input the weight of the current load into the processing model to obtain the corresponding target distance;

[0083] The control driving mechanism 342 drives the moving mechanism 341 to adjust the distance between the front bearing 320 and the rear bearing 330 to a target distance.

[0084] 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 load weight of each group of experiments is M i The pressure test device measures the optimal distance L for each load weight. i , so that we get N sets of sample data; among them, the drum load is M i When the load rotates, if the distance between the front bearing and the rear bearing is the optimal distance L i When the front bearing and the rear bearing are relatively balanced.

[0085] 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.

[0086] In some embodiments, see Figure 6 , Figure 6 Another flow chart of the control method provided in the embodiment of the present application. The control method includes the following steps S201-S205:

[0087] Step S201: obtaining the weight M of the current load in the drum 100;

[0088] Step S202: generating a corresponding control signal according to the weight M;

[0089] Step S203: adjusting the magnetic field strength of the electromagnetic device 3422 according to the control signal to drive the motion mechanism 341 to move toward a preset position to adjust the distance between the front bearing 320 and the rear bearing 330;

[0090] Step S204: determining whether the motion mechanism 341 actually moves to the preset position;

[0091] The actual position of the motion mechanism 341 can be detected by the position detection device 343, and then the processing unit of the laundry processing device 10 determines whether the motion mechanism 341 has actually reached the preset position by comparing the actual position with the preset position. If the motion mechanism 341 has actually moved to the preset position, step S205 is entered, otherwise, step S203 is returned.

[0092] Step S205: Adjustment is completed.

[0093] The control method provided in the embodiment of the present application drives the motion mechanism 341 according to the load weight in the drum 100. When the load weight in the drum 100 changes, the span of the front and rear bearings 330 can be adjusted to balance the force on the front bearing 320 and the rear bearing 330 when the drum 100 rotates, thereby avoiding damage to the bearings due to excessively uneven force, extending the service life of the clothing processing device 10, and bringing a better user experience to the user.

[0094] The present application also provides a control device, which is applied to the above-mentioned clothes processing device 10, see Figure 7 , Figure 7 The control device 500 includes an acquisition module 510 and a control module 520 .

[0095] The acquisition module 510 is used to acquire the weight of the current load in the drum 100 ; the control module 520 is used to control the driving mechanism 342 to drive the motion mechanism 341 according to the weight, so as to adjust the distance between the front bearing 320 and the rear bearing 330 .

[0096] The control device provided in the embodiment of the present application drives the motion mechanism 341 according to the load weight in the drum 100. When the load weight in the drum 100 changes, it can adjust the span of the front and rear bearings 330 to balance the forces on the front bearing 320 and the rear bearing 330 when the drum 100 rotates, thereby avoiding damage to the bearings due to excessively uneven forces, extending the service life of the clothing processing device 10, and providing users with a better user experience.
