Abstract
Description
Technical Field
[0001] This utility model relates to the field of clothing processing technology, and in particular to a clothing processing device. Background Technology
[0002] A clothes dryer is a household appliance used for quickly drying clothes. It simulates natural air drying by using heating, ventilation, and rotation functions to remove moisture from clothes in a short time, leaving them dry and fluffy. Inside, a dryer typically features a rotating drum. Clothes are placed inside, and a motor drives the drum to rotate, ensuring even heating. Simultaneously, the heating system generates hot air, which circulates within the drum under the action of a fan, carrying away moisture from the clothes. The humid air is then expelled outside the machine through a ventilation system. In short, clothes dryers offer numerous advantages and provide great convenience to people's daily lives.
[0003] Currently, the rotation of the dryer drum is often achieved by a motor driving a belt, which in turn drives the drum. This drive method has several drawbacks: numerous transmission components result in significant energy loss during transmission; furthermore, it leads to considerable noise and vibration during drum rotation, negatively impacting the user experience. A current approach involves directly installing the drive unit at the rear of the dryer drum to rotate it. This design requires a sealed housing in the reducer section to prevent lubricant leakage. Without this housing, the reducer's sealing performance cannot be guaranteed, leading to grease leakage or moisture from the dryer drum entering the reducer, potentially causing damage.

[0040] The garment handling device of this solution includes a drive assembly, which comprises a motor assembly and a reducer. The reducer may include a rear housing, an input shaft, a planetary gear assembly, and a planet carrier. A space for accommodating the planetary gear assembly is formed between the input shaft, the rear housing, and the planet carrier. The entire reducer does not have a housing that matches the rear housing, simplifying the overall structure of the reducer. Furthermore, by designing a first seal between the planet carrier and the rear housing, the planetary gear assembly is sealed within the space between the input shaft, the rear housing, and the planet carrier. This prevents lubricating oil leakage from the planetary gear assembly and also prevents external moisture from entering the planetary gear assembly through the gap between the planet carrier and the rear cover, thereby preventing damage to the reducer assembly and extending the reducer's service life.
[0041] In this design, the second reinforcing rib of the reducer extends along the outer periphery of the planetary carrier and away from the rear housing. This increases the strength of the planetary carrier and the contact area between the first seal and the planetary carrier, thereby improving stability and sealing.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0063] As a specific embodiment of this utility model, such as Figure 1-5 As shown, this embodiment provides a garment processing device 100, which may include a drive assembly 400, which 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, and a planet carrier 424. The rear housing 421 is connected to the inner side of the stator 411 and includes 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, and the planet carrier 424 is disposed on the side of the planetary gear assembly 423 away from the rear housing 421. 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. A first seal 430 is provided between the planet carrier 424 and the rear housing 421 to prevent lubricating oil leakage from the planetary gear assembly 423.
[0064] Specifically, the garment processing device 100 of this embodiment includes a drive assembly 400, which includes a motor assembly 410 and a reducer 420. The reducer 420 may include a rear housing 421, an input shaft 422, a planetary gear assembly 423, and a planet carrier 424. A space for accommodating the planetary gear assembly 423 is formed between the input shaft 422, the rear housing 421, and the planet carrier 424. The entire reducer 420 does not have a housing that matches the rear housing 421, simplifying the structure of the entire reducer 420. In addition, by designing a first seal 430 between the planet carrier 424 and the rear housing 421, the planetary gear assembly 423 is sealed in the space between the input shaft 422, the rear housing 421, and the planet carrier 424, which prevents lubricating oil leakage at the planetary gear assembly 423 and also prevents external moisture from entering the planetary gear assembly 423 through the gap between the planet carrier 424 and the rear cover, thereby preventing damage to the reducer 420 assembly and extending the service life of the reducer 420.
[0065] Specifically, unless otherwise specified, in this embodiment, the inner side refers to the side closer to the axis of the input shaft 422, and the outer side refers to the side farther from the axis of the input shaft 422.
[0066] As a specific embodiment of this utility model, such as Figures 3-5 As shown, the rear housing 421 of this embodiment may include a fixing part 4212 and a first transmission part 4213. The fixing part 4212 has a first through hole 4211 on its inner side and is connected to the stator 411 on its outer side. The first transmission part 4213 extends from the outer side of the fixing part 4212 toward the planetary gear assembly 423, and a space for accommodating the planetary gear assembly 423 is formed between the first transmission part 4213, the fixing part 4212, and the input shaft 422.
[0067] Specifically, in this embodiment, the rear shell 421 serves two purposes: firstly, it transmits power to the planetary gear assembly 423; secondly, it acts as the housing of the reducer 420, enclosing the planetary gear assembly 423 and the planet carrier 424.
[0068] More specifically, the plane of the fixed part 4212 is perpendicular to the shaft through which the input shaft 422 rotates. The first transmission part 4213 is substantially perpendicular to the fixed part 4212. Preferably, the first transmission part 4213 is perpendicular to the fixed part 4212.
[0069] As a specific embodiment of this utility model, such as Figures 3-5 As shown, the planetary carrier 424 of this embodiment is provided with a second reinforcing rib 4245 extending away from the rear shell 421 on its outer periphery, and the first sealing member 430 is located between the second reinforcing rib 4245 and the first transmission part 4213.
[0070] Specifically, in this embodiment, the second reinforcing rib 4245 extends along the outer periphery of the planetary carrier 424 and in a direction away from the rear shell 421. This increases the strength of the planetary carrier 424 and increases the contact area between the first seal 430 and the planetary carrier 424, thereby improving stability and sealing.
[0071] As a specific embodiment of this utility model, the first transmission part 4213 of this embodiment is provided with a groove 4215 on the side near the first sealing member 430 (e.g. Figure 4 As shown), the first sealing member 430 abuts between the second reinforcing rib 4245 and the groove 4215. Specifically, in this embodiment, the groove 4215 can limit the first sealing member 430 on the one hand, and increase the sealing performance of the contact between the first sealing member 430 and the first transmission part 4213 on the other hand.
[0072] Specifically, the garment handling device 100 of this embodiment may further include a rear support member 300, which is located on the side of the first transmission part 4213 near the planetary gear assembly 423, and the first seal member 430 is located between the second reinforcing rib 4245, the groove 4215 and the rear support member 300.
[0073] Specifically, in this embodiment, the first sealing element 430 is disposed between the rear support 400, the second reinforcing rib 4245, and the groove 4215 to ensure the stability and sealing performance of the first sealing element 430 during installation. From the perspective of the illustration, the inner side of the first sealing element 430 abuts against the second reinforcing rib 4245, the outer side and upper side abut against the bottom and upper part of the groove 4215 respectively, and the lower side of the first sealing element 430 abuts against the rear support, thereby stabilizing the first sealing element 430 from four directions. Furthermore, since there is a gap between the second reinforcing rib 4245 and the groove 4215, the second reinforcing rib 4245 can be installed through this gap, effectively sealing it.
[0074] As a specific embodiment of this utility model, such as Figures 6-8 As shown, the first sealing member 430 of this embodiment has a notch-shaped cross-section, and the opening of the notch faces away from the rear support member. The notch-shaped first sealing member 430 of this embodiment may include an inner wall 431, an outer wall 432, and a bottom wall 433. The inner wall 431 abuts against the second reinforcing rib 4245, the outer wall 432 abuts against the bottom of the groove 4215, and the top of the outer wall 432 (… Figure 4 and Figure 8 The first seal 430 (in the direction shown) abuts against the upper wall of the groove 4215, while the bottom wall 433 abuts against the rear support 300. This notch-shaped first seal 430 not only seals the inside of the reducer 420, but also has the function of storing lubricating oil.
[0075] Specifically, in this embodiment, the inner wall 431 of the notch near the reinforcing rib is an inclined surface. A protrusion 434 extending from the first sealing member 430 toward the reinforcing rib is provided on the inner wall 431 of the notch near the reinforcing rib. The protrusion 434 abuts against the second reinforcing rib 4245 and the rear support member 300. The inner wall 431 and the protrusion 434 further enhance the sealing between the second reinforcing rib 4245 and the first sealing member 430.
[0076] Specifically, the first sealing element 430 in this embodiment may include internal metal ribs and external rubber. The use of metal ribs can increase the strength of the first sealing element 430, while the rubber covering the metal ribs can improve flexibility and sealing performance, and also resist vibration and prevent abnormal noise.
[0077] Specifically, the garment handling device 100 of this embodiment may further include a cylindrical body 200 and a rear support member 300. The cylindrical body 200 may include a front wall 210 having a garment loading port and a rear wall 220 opposite to the front wall 210. The rear support member 300 is disposed between the rear wall 220 of the cylindrical body 200 and the drive assembly 300. An air duct 310 communicating with the interior of the cylindrical body 200 is provided inside the rear support member 300.
[0078] Furthermore, the garment handling device 100 of this embodiment may also include a rear cover plate, which is located on the side of the rear support member 300 away from the cylinder 200, and the rear cover plate covers the drive assembly 400. In this embodiment, the drive assembly 400 is supported by the rear support member 300, and is not directly supported by the rear cover plate. This avoids the situation in the prior art where the rear cover plate is directly used to support the drive assembly and the cylinder, which would cause the rear cover plate to be subjected to excessive force and deform or be damaged. It also avoids the situation where the air duct 310 is directly inside the rear cover plate, which would result in poor heat preservation and thus increase fuel consumption.
[0079] As a specific embodiment of this utility model, such as Figure 3 and Figure 9 As shown, in this embodiment, a rib 360 is provided at the rear support member 300 around the mounting hole 350. The rib 360 protrudes towards the drive assembly 400. The drive assembly 400 and the rib 360 are connected by fasteners so that the drive assembly 400 is fixed at the rear support member 300.
[0080] Specifically, in this embodiment, the rear support member 300 is provided with a protruding rib 360 that is connected to the drive assembly 400. On the one hand, the protruding rib 360 can match the structure of the drive assembly 400 and thus be fixedly installed with the stator. On the other hand, the protruding rib 360 can increase the strength at the installation position of the rear support member 300 and prevent the rear support member 300 from deforming at the connection position with the drive assembly 400.
[0081] Specifically, the cross-section of the rib 360 after being cut in a plane parallel to the rear side of the cylinder 200 is a closed structure. Specifically, in this embodiment, the cross-section of the rib 360 can be circular, and the circle is coaxially arranged with the mounting hole 350.
[0082] The closed structure formed by the cross-section of the rib 360 increases its structural strength, preventing damage or deformation due to insufficient strength when connected to the drive assembly 400, and ensuring an unstable connection between the rib 360 and the drive assembly 400. More specifically, in this embodiment, the cross-section of the rib 360 is a closed circular structure, with the center of the circle overlapping the center of the mounting hole 350.
[0083] Furthermore, in this embodiment, the rib 360 has a mounting portion 370 at each connection point with the drive assembly 400, which is larger than the dimensions of other parts, and a screw hole 380 is provided at the mounting portion 370. By increasing the size of the rib 360 at the connection position, the strength of the rib 360 can be further increased.
[0084] More specifically, a first reinforcing rib 390 is provided on the outer wall of the protruding rib 360. The first reinforcing rib 390 can be a strip-shaped reinforcing rib extending from the bottom of the protruding rib 360 away from the groove 340, or it can be a reinforcing rib of other shapes. Specifically, in this embodiment, the first reinforcing rib 390 can increase the strength of the protruding rib 360, making the connection between the protrusion and the drive assembly 400 more stable.
[0085] Similarly, a third reinforcing rib 311 is provided on the side of the rear support member 300 away from the cylinder 200. The dimension of the third reinforcing rib 311 in the direction of the axis of rotation of the cylinder 200 is smaller than the dimension of the raised rib 360.
[0086] Specifically, in this embodiment, the first reinforcing rib 390 and the third reinforcing rib 311 can be reinforcing ribs of various shapes, such as dot-shaped, strip-shaped, or grid-shaped. The main function of the third reinforcing rib 311 is to increase the strength of the support portion 330.
[0087] Specifically, such as Figure 4 and Figure 5 As shown, in this embodiment, a first bearing 426 is provided between the outer wall of the input shaft 422 and the inner wall of the first through hole 4211, so that the input shaft 422 is rotatably connected to the rear housing 421. Since the rear housing 421 is fixedly connected to the stator 411, and the input shaft 422 is connected to 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 housing 421, therefore, the first bearing 426 is provided between the outer wall of the input shaft 422 and the first through hole 4211 of the rear housing 421. On the one hand, the rear housing 421 can support the input shaft 422, and on the other hand, it does not affect the rotation of the input shaft 422.
[0088] More specifically, a bearing sleeve 427 is also provided between the first bearing 426 and the inner wall of the first through hole 4211. The bearing sleeve 427 can improve the load-bearing capacity of the mechanical structure, reduce the wear between the first bearing 426 and the rear housing 421, prevent lubricating oil from leaking through the gap between the first bearing 426 and the rear cover, and enable better assembly between the first bearing 426, the rear cover, and the input shaft 422, thus ensuring the stability of the machine.
[0089] Specifically, in this embodiment, the input shaft 422 passes through the first through hole 4211 along the axial direction of the rotation of the input shaft 422. A connecting part 4221 is provided on the side of the input shaft 422 located near the rotor 412 on the rear housing 421. The input shaft 422 is connected to the rotor 412 through the connecting part 4221 so as to rotate with the rotor 412.
[0090] In this embodiment, the input shaft 422 passes through the first through hole 4211 from one side of the rotating shaft and reaches the other side of the rear shell 421, transmitting the rotational power of the rotor 412 to the other side of the rear shell 421.
[0091] Specifically, the connecting portion 4221 is formed as a flange extending radially outward from the outer side wall of the input shaft 422. The flanged structure of the connecting portion 4221 facilitates connection with the rotor 412 and also facilitates power transmission.
[0092] As a specific embodiment of this utility model, the rear shell 421 may include a fixing part 4212 and a first transmission part 4213. The fixing part 4212 has a first through hole 4211 on its inner side and is connected to the stator 411 on its outer side. The first transmission part 4213 extends from the outer side of the fixing part 4212 in a direction away from the rotor 412, and a space for accommodating the planetary gear assembly 423 is formed between the first transmission part 4213, the fixing part 4212, and the input shaft 422.
[0093] Specifically, in this embodiment, the rear shell 421 serves two purposes: firstly, it transmits power to the planetary gear assembly 423; secondly, it acts as the housing of the reducer 420, enclosing the planetary gear assembly 423 and the planet carrier 424.
[0094] More specifically, the plane of the fixed part 4212 is perpendicular to the shaft through which the input shaft 422 rotates. The first transmission part 4213 is substantially perpendicular to the fixed part 4212. Preferably, the first transmission part 4213 is perpendicular to the fixed part 4212.
[0095] As a specific embodiment of this utility model, the input shaft 422 may further include a second through hole 4222 coaxial with the first through hole 4211. The planetary carrier 424 may include a second transmission part 4241 and a third transmission part 4242. The second transmission part 4241 is disposed in the second through hole 4222 and is rotatably connected to the input shaft 422. The third transmission part 4242 extends from the second transmission part 4241 to the position where the planetary gear assembly 423 is installed, so as to be rotatably connected to the planetary gear assembly 423, and rotates relative to the input shaft 422 under the drive of the planetary gear assembly 423.
[0096] Specifically, in this embodiment, the second transmission part 4241 is rotatably connected to the input shaft 422. On the one hand, the input shaft 422 supports the third transmission part 4242. On the other hand, the second transmission part 4241 is disposed in the second through hole 4222 of the input shaft 422 and is coaxially disposed with the second through hole 4222 to ensure the coaxiality of the power transmission.
[0097] Furthermore, the third transmission section 4242 extends from the second transmission section 4241 to the first transmission section 4213 near the rear housing 421, so that the planetary gear assembly 423 drives the planetary carrier 424 to rotate under the drive and constraint of the input shaft 422, the rear housing 421, and the third transmission section 4242. In this embodiment, the third transmission section 4242 is not only part of the planetary carrier 424, but can also serve as a cover plate for the entire reducer 420, forming a closed structure with the rear housing 421 to accommodate the planetary gear assembly 423. This reduces the use of a cover plate for the reducer 420, simplifies the mechanical structure of the drive device 400, and reduces the overall size of the drive device 400.
[0098] Specifically, in this embodiment, a second bearing 428 is provided 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 provision of the second bearing 428 can limit and support the planetary carrier 424 using the input shaft 422, and does not affect the relative rotation between the planetary carrier 424 and the input shaft 422.
[0099] Specifically, in this embodiment, the third transmission part 4242 is provided with a recessed clearance groove 4243 on the side near the input shaft 422, which is recessed away from the input shaft 422, in order to avoid interference between the input shaft 422 and the third transmission part 4242.
[0100] As a specific embodiment of this utility model, such as Figure 5 , Figure 10 and Figure 11As shown, in this embodiment, a first gear 4223 is provided on the outer wall of the portion of the input shaft 422 located away from the connecting portion 4221 in the fixed portion 4212. A second gear 4214 is provided on the inner wall of the first transmission portion 4213 of the rear housing 421. A plurality of rotating shafts 4244 are provided at the third transmission portion 4242 of the planetary carrier 424. The planetary gear assembly 423 includes a plurality of planetary gears 4231, each planetary gear 4231 being rotatably fitted onto a corresponding rotating shaft 4244. The inner side of each planetary gear 4231 meshes with the first gear 4223, and the outer side of each planetary gear 4231 meshes with the second gear 4214, so that when the input shaft 422 rotates, the first gear 4223 drives the planetary gears 4231 to rotate along the rear housing 421, and then the rotating shaft 4244 drives the planetary carrier 424 to rotate.
[0101] Specifically, the rotation of the input shaft 422 is transmitted to the planet carrier 424 through the first gear 4223 of the input shaft 422, the second gear 4214 of the rear housing 421, and the planetary gear assembly 423, thereby completing the speed reduction transmission process and increasing the transmitted torque.
[0102] Specifically, the planetary gear assembly 423 of this embodiment may include multiple planetary gears 4231, such as three, five or more. The planetary gear assembly 423 in this embodiment includes five small planetary gears 4231. Five rotating shafts 4244 are designed at the third transmission part 4242 of the planetary carrier 424. The planetary gears 4231 are sleeved on the rotating shafts 4244, meshing internally with the first gear 4223 of the input shaft 422 and externally with the second gear 4214 of the rear housing 421. Thus, when the input shaft 422 rotates, the first gear 4223 drives the planetary gears 4231 to rotate along the second gear 4214 of the rear housing 421, which in turn drives the planetary carrier 424 to rotate via the rotating shafts 4244, thereby transmitting the power from the input shaft 422 to the planetary carrier 424.
[0103] Preferably, the number of planetary gears 4231 and the number of rotating shafts 4244 are the same, and they are evenly distributed above the planet carrier 424. In this embodiment, the number of planetary gears 4231 and rotating shafts 4244 are preferably 5, and they are evenly distributed on the outer periphery of the input shaft 422 to ensure that the transmitted power is evenly transmitted to the planet carrier 424.
[0104] More specifically, a second reinforcing rib 4245 is also provided at the planet carrier 424 in this embodiment. This second reinforcing rib 4245 can strengthen the third transmission part 4242 of the planet carrier 424. Specifically, the second reinforcing rib 4245 can extend along the outer periphery of the planet carrier 424 in a direction away from the planet gear 4231. To achieve overall miniaturization, a clearance groove 312 is provided at the rear support member 300. The clearance groove 312 not only avoids the increased volume caused by the overall clearance of the planet carrier 424, but also prevents interference between the planet carrier 424 and the rear support member 300.
[0105] Specifically, in this embodiment, the second transmission part 4241 of the planetary carrier 424 is provided with a third through hole 4246 coaxial with the first through hole 4211. The output shaft 425 is fixedly connected to the planetary carrier 424 at the third through hole 4246 via a spline, so as to rotate with the planetary carrier 424.
[0106] Specifically, in this embodiment, the output shaft 425 is disposed at the third through hole 4246. The third through hole 4246 is coaxially disposed with the first through hole 4211 and also with 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, thus transmitting the power of the rotor 412 coaxially.
[0107] As a specific embodiment of this utility model, such as Figure 3 and Figure 9 As shown, in this embodiment, a bearing 313 is provided between the inner wall of the mounting hole 350 of the rear support member 300 and the output shaft 425 to allow the output shaft 425 to rotate relative to the rear support member 300. The bearing 313 allows the rear support member 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.
[0108] Specifically, a second seal 314 is provided between the inner wall of the mounting hole 350 of the rear support 300 and the output shaft 425. The second seal 314 can be provided on the side of the bearing 313 near the cylinder 200, thereby preventing moisture inside the cylinder 200 from entering the drive assembly 400, and also protecting the bearing 313 from lubricating oil leakage.
[0109] Specifically, an insert 315 is provided at the mounting hole 350 of the rear support member 300, and the bearing 313 and the second seal 314 are both disposed between the insert 315 and the output shaft 425. The design of the insert 315 can ensure the support strength of the rear support member 300 for the output shaft 425.
[0110] In this embodiment, the insert 315 is a metal insert, which can increase the stability of the bearing 313 installation and the sealing performance of the second seal 314 installation.
[0111] Specifically, the structure of the second seal 314 in this embodiment is basically the same as that of the first seal 430, both being oil seal structures.
