[0052] In the description of the present embodiment, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", "front", "rear", etc. indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present utility model.

[0053] As a specific embodiment of the present utility model, such as Figures 1-3As shown, this embodiment provides a garment processing device 100, which may include a drive assembly 400. The drive assembly 400 may include a motor assembly 410 and a reducer 420. The motor assembly 410 may include a stator 411 and a rotor 412 that rotates relative to the stator 411. The reducer 420 may include a rear housing 421, an input shaft 422, a planetary gear assembly 423, a planet carrier 424, and an output shaft 425. The rear housing 421 is connected to the inner side of the stator 411 and may include a first through hole 4211. The input shaft 422 is fixedly connected to the rotor 412 to rotate with the rotor 412. The input shaft 422 is disposed at the first through hole 4211 of the rear housing 421 and rotates relative to the rear housing 421. The planetary gear assembly 423 is disposed between the input shaft 422 and the rear housing 421. The planet carrier 424 is disposed on the side of the planetary gear assembly 423 away from the rear housing. When the input shaft 422 drives the planetary gear assembly 423 to rotate, the planetary gear assembly 423 drives the planet carrier 424 to rotate. The planet carrier 424 is fixed to the output shaft 425 so that when the planet carrier 424 rotates, it drives the output shaft 425 to rotate.

[0054] Specifically, the clothing processing device 100 of this embodiment may include a drive assembly, and the drive assembly 400 may include a motor assembly 410 and a reducer 420. The motor assembly 410 may include a stator 411 and a rotor 412. The reducer 420 may include a rear housing 421, an input shaft 422, a planetary gear assembly 423, a planetary carrier 424, and an output shaft 425. The stator 411 is fixedly connected to the rear housing 421, and the rotor 412 is fixedly connected to the input shaft 422. When the rotor 412 rotates under the drive of the stator 411, it drives the input shaft 422 to rotate, thereby driving the planetary gear assembly 423, the planetary carrier 424, and the output shaft 425 to rotate, thereby completing the power transmission. The drive assembly 400 of this embodiment has smooth power transmission and a simple structure, which can reduce the cost and size of the drive assembly 400, thereby expanding its application range.

[0055] Specifically, in this embodiment, "inner side" and "outer side" refer to the axis closer to the input shaft 422 as the inner side and the axis farther away from the input shaft 422 as the outer side unless otherwise specified.

[0056] Specifically, such as Figure 4As shown, the stator 411 of the embodiment can include a support portion 4111 and a coil 4112 connected outside the support portion 4111. The support portion 4111 is provided with a mounting interface 4113, which is connected with the rear shell 421 and coaxial with the support portion 4111 when the rear shell 421 is press-fitted in the support portion 4111 and cannot rotate relative to the support portion 4111. The rotor 412 covers one side of the rear shell 421 and the stator 411, and the rotor 412 is connected with the input shaft 422. When the coil 4112 of the stator 411 is energized, the rotor 412 rotates relative to the stator 411, thereby driving the input shaft 422 to rotate. Specifically, as shown Figure 3 and Figure 5 As shown, the outer side wall of the input shaft 422 is provided with a first bearing 426 between the inner side wall of the first through hole 4211, so that the input shaft 422 is rotatably connected with the rear shell 421. Since the rear shell 421 is fixedly connected with the stator 411, the input shaft 422 is connected with the rotor 412, the rotor 412 needs to rotate together with the input shaft 422, and the input shaft 422 needs to pass through the rear shell 421, so the first bearing 426 is arranged between the outer side wall of the input shaft 422 and the first through hole 4211 of the rear shell 421. On the one hand, the rear shell 421 can support the input shaft 422, and on the other hand, it does not affect the rotation of the input shaft 422.

[0057] More specifically, a bearing sleeve 427 is further arranged between the first bearing 426 and the inner side wall of the first through hole 4211. The bearing sleeve 427 can improve the carrying capacity of the mechanical structure, reduce the wear of the first bearing 426 and the rear shell 421, prevent the leakage of lubricating oil from the gap between the first bearing 426 and the rear cover plate, and better assemble the first bearing 426, the rear cover plate and the input shaft 422, thereby ensuring the stability of the machine.

[0058] Specifically, the input shaft 422 of the embodiment passes through the first through hole 4211 along the axial direction of the input shaft 422, and the input shaft 422 is provided with a connecting portion 4221 on the side of the rear shell 421 away from the planetary gear assembly 423. The input shaft 422 is connected with the rotor 412 through the connecting portion 4221 to rotate with the rotor 412.

[0059] The input shaft 422 of the embodiment passes through the first through hole 4211 from one side of the shaft to the other side of the rear shell 421, and transmits the rotating power of the rotor 412 to the other side of the rear shell 421.

[0060] Specifically, the connecting portion 4221 is formed as a flange extending radially outward from the outer side wall of the input shaft 422. The connecting portion 4221 is formed as a flange structure, which is convenient for connection with the rotor 412 and transmission of power.

[0061] As a specific embodiment of the utility model, the rear shell 421 of the embodiment can include a fixed part 4212 and a first transmission part 4213. Among them, the inner side of the fixed part 4212 has a first through hole 4211, and the outer side is connected with the stator 411. The first transmission part 4213 extends from the outer side of the fixed part 4212 to the direction close to the planetary gear assembly 423, and the space accommodating the planetary gear assembly 423 is formed between the first transmission part 4213, the fixed part 4212 and the input shaft 422.

[0062] Specifically, the rear shell 421 of the embodiment plays a role of transmitting the power of the planetary gear assembly 423 on the one hand, and serves as the housing of the speed reducer 420 on the other hand, wrapping the planetary gear assembly 423 and the planet carrier 424.

[0063] More specifically, the plane where the fixed part 4212 is located is perpendicular to the rotation shaft of the input shaft 422. The first transmission part 4213 is basically perpendicular to the fixed part 4212. Preferably, the first transmission part 4213 is perpendicular to the fixed part 4212.

[0064] As a specific embodiment of the utility model, the input shaft 422 of the embodiment can further include a second through hole 4222 coaxial with the first through hole 4211. The planet carrier 424 can include a second transmission part 4241 and a third transmission part 4242. Among them, the second transmission part 4241 is arranged in the second through hole 4222 and is rotatably connected with the input shaft 422. The third transmission part 4242 is extended from the second transmission part 4241 to the position where the planetary gear assembly 423 is installed, so as to be rotatably connected with the planetary gear assembly 423 and rotate relative to the input shaft 422 under the drive of the planetary gear assembly 423.

[0065] Specifically, the second transmission part 4241 of the embodiment is rotatably connected with the input shaft 422, which is supported by the input shaft 422 on the one hand, and the second transmission part 4241 is arranged in the second through hole 4222 of the input shaft 422 and is coaxially arranged with the second through hole 4222, which ensures the coaxiality of power transmission.

[0066] In addition, the third transmission part 4242 is extended from the second transmission part 4241 to the first transmission part 4213 close to the rear shell 421, so that the planetary gear assembly 423 drives the planet carrier 424 to rotate under the drive and limitation of the input shaft 422, the rear shell 421 and the third transmission part 4242. The third transmission part 4242 of the embodiment is not only a part of the planet carrier 424, but also can serve as a cover plate of the entire speed reducer 420, forming a closed structure with the rear shell 421 to accommodate the planetary gear assembly 423, reducing the use of the cover plate of the speed reducer 420, reducing the mechanical structure of the driving assembly 400 and reducing the volume of the entire driving assembly 400.

[0067] Specifically, the second bearing 428 is arranged between the outer side of the second transmission part 4241 and the inner side of the second through hole 4222 of the input shaft 422. Similarly, the arrangement of the second bearing 428 can not only limit and support the planetary carrier 424 by the input shaft 422, but also does not affect the relative rotation between the planetary carrier 424 and the input shaft 422.

[0068] Specifically, the third transmission part 4242 of the embodiment is provided with a recessed groove 4243 away from the input shaft 422 on the side close to the input shaft 422, so as to avoid the input shaft 422. The design of the recessed groove 4243 avoids the interference between the input shaft 422 and the third transmission part 4242.

[0069] As a specific embodiment of the utility model, the outer side wall of the input shaft 422 of the embodiment is provided with the first gear 4223 away from the connecting part 4221 of the fixed part 4212. The inner side wall of the first transmission part 4213 of the rear shell 421 is provided with the second gear 4214. The third transmission part 4242 of the planetary carrier 424 is provided with a plurality of rotating shafts 4244. The planetary gear assembly 423 comprises a plurality of planetary gears 4231, each planetary gear 4231 is rotatably sleeved on the corresponding rotating shaft 4244. The inner side of each planetary gear 4231 is engaged with the first gear 4223, and the outer side of each planetary gear 4231 is engaged with the second gear 4214, so that the input shaft 422 is rotated to drive the planetary gear 4231 to rotate along the rear shell 421 through the first gear 4223, and then the planetary carrier 424 is driven to rotate through the rotating shaft 4244.

[0070] Specifically, through the first gear 4223 of the input shaft 422, the second gear 4214 of the rear shell 421 and the planetary gear assembly 423, the rotation of the input shaft 422 is transmitted to the planetary carrier 424, the speed reduction transmission process is completed, and the transmission torque is increased.

[0071] Specifically, a sealing member 430 is further arranged between the third transmission part 4242 of the planetary carrier 424 and the first transmission part 4213 of the rear shell 421, which is an oil seal and can prevent external moisture from entering the planetary gear assembly 423 to damage the planetary gear assembly 423, and can prevent the lubricating oil in the planetary gear assembly 423 from leaking.

[0072] Specifically, as Figure 6 and Figure 7As shown, the planetary wheel assembly 423 of the embodiment can include a plurality of planetary wheels 4231, for example, 3, 5 or more. The planetary wheel assembly 423 in the embodiment includes 5 small planetary wheels 4231. The third transmission part 4242 of the carrier 424 is designed with 5 rotating shafts 4244, the planetary wheels 4231 are sleeved at the rotating shafts 4244, the inside is engaged with the first gear 4223 of the input shaft 422, and the outside is engaged with the second gear 4214 of the rear shell 421, so that when the input shaft 422 rotates, the planetary wheels 4231 are driven to rotate along the second gear 4214 of the rear shell 421 through the first gear 4223, and the carrier 424 is driven to rotate through the rotating shafts 4244, thereby transmitting the power of the input shaft 422 to the carrier 424.

[0073] Preferably, the number of planetary wheels 4231 and rotating shafts 4244 is the same and uniformly distributed above the carrier 424. The number of planetary wheels 4231 and rotating shafts 4244 in the embodiment is preferably 5, and they are uniformly distributed at the outer periphery of the input shaft 422, so that the transmitted power is uniformly transmitted to the carrier 424.

[0074] More specifically, the carrier 424 of the embodiment is further provided with a second reinforcing rib 4245. The second reinforcing rib 4245 can strengthen the strength of the third transmission part 4242 of the carrier 424. Specifically, the second reinforcing rib 4245 can extend away from the planetary wheels 4231 along the outer periphery of the carrier 424.

[0075] Specifically, the second transmission part 4241 of the carrier 424 of the embodiment is provided with a third through hole 4246 coaxial with the first through hole 4211. The output shaft 425 is fixedly connected with the carrier 424 at the third through hole 4246 through the spline, so as to rotate with the carrier 424.

[0076] Specifically, the output shaft 425 of the embodiment is arranged at the third through hole 4246, and the third through hole 4246 is coaxially arranged with the first through hole 4211 and the second through hole 4222, so that the rotating shaft of the output shaft 425 is coaxial with the rotating shaft of the input shaft 422, and the power of the rotor 412 is coaxially transmitted.

[0077] As a specific embodiment of the utility model, Figure 1 Figure 8 and Figure 9As shown, the clothes treatment device 100 of the embodiment can further include a drum 200, a rear support 300 and a rear cover plate. The drum 200, the rear support 300 and the rear cover plate are sequentially arranged. The driving assembly 400 is arranged at the rear support 300. The rear support 300 is provided with a mounting hole 350, and the output shaft 425 of the driving assembly 400 passes through the mounting hole 350 from the position between the rear support 300 and the rear cover plate to the drum 200. Specifically, the drum 200 of the embodiment can include a front wall 210 with a clothes feeding opening and a rear wall 220 opposite to the front wall 210. The output shaft 425 of the driving assembly 400 is connected with the rear wall 220 of the drum 200 to drive the drum 200 to rotate. The clothes treatment device 100 with the driving assembly 400, on the one hand, discards the traditional intermediate transmission components such as belts and gears, greatly reduces the loss in the energy transmission process, has a significant energy-saving effect, and when working, the motor generates a rotating magnetic field by electromagnetic induction to drive the drum to rotate accurately and stably, so that the clothes in the drum can be uniformly heated. In addition, the clothes treatment device 100 using the driving assembly 400 of the embodiment has small noise and small vibration, improving the user experience. The simple structure and small size of the driving assembly 400 of the embodiment make the clothes treatment device 100 using the driving assembly 400 can be designed to have a large drum 200 space and a small overall structure size, thereby making the space utilization of the clothes treatment device 100 higher.

[0078] The driving assembly 400 of the clothes treatment device 100 of the embodiment is arranged at the rear support 300, which supports the driving assembly 400 by the rear support 300 and drives the drum 200 to rotate, avoiding the direct arrangement of the driving assembly 400 at the rear cover plate of the clothes treatment device 100, avoiding the easy damage of the rear cover plate to shorten the service life of the clothes treatment device 100, and also avoiding the problem of poor user experience caused by easy vibration of the clothes treatment device 100.

[0079] The driving assembly 400 of the embodiment is directly connected at the rear wall 220 of the drum 200 to directly drive the drum 200 to rotate, which eliminates the traditional intermediate transmission devices such as belts and gears, reduces energy loss and transmission error, and can more efficiently and accurately control the rotation of the drum 200.

[0080] As a specific embodiment of the utility model, Figure 9 As shown, the inner side wall of the mounting hole 350 of the rear support 300 of the embodiment and the output shaft 425 are provided with a bearing 313 to enable the output shaft 425 to rotate relative to the rear support 300. The bearing 313 enables the rear support 300 to support the output shaft 425 on the one hand and not to hinder the rotation of the output shaft 425 on the other hand.

[0081] Specifically, the inner side wall of the mounting hole 350 of the rear support 300 and the output shaft 425 are further provided with a sealing member 314. The sealing member 314 can be arranged on the side of the bearing 313 close to the barrel 200, thereby avoiding the moisture in the barrel 200 from entering the driving assembly 400, and protecting the bearing 313 from leaking lubricating oil.

[0082] Specifically, the mounting hole 350 of the rear support 300 is provided with an insert 315, and the bearing 313 and the sealing member 314 are arranged between the insert 315 and the output shaft 425. The design of the insert 315 can ensure the support strength of the rear support 300 to the output shaft 425.

[0083] The insert 315 of the embodiment is a metal insert, which can increase the stability of the bearing 313 and the sealing performance of the sealing member 314.
