[0054] Figure 2 for Figure 1 Schematic diagram of the rear side of the inner and outer cylinders; Figure 3 for Figure 2 A cross-sectional view of point AA.

[0055] like Figure 2 As shown, in some embodiments, the tubular assembly may include an outer tub 12. The outer tub 12 may be disposed within the housing 1. The outer tub 12 is fixed relative to the interior of the housing 1. The outer tub 12 is a shell structure with a nozzle, the nozzle of which faces the interior of the housing 1 at the front side. The outer tub 12 is configured as a tub for containing washing water, that is, the internal space of the outer tub 12 can be used to hold washing liquid, such as water.

[0056] In some embodiments, the tubular assembly may include an inner tub (not shown). The inner tub is rotatably disposed within the internal space of the outer tub 12, and a garment handling chamber may be formed within the inner tub for holding garments to be washed. The opening of the inner tub may be directly opposite the opening of the outer tub 12, that is, the front opening of the garment handling chamber is directly opposite the opening of the outer tub 12 and the garment loading port. Therefore, garments can sequentially enter the garment handling chamber from the garment loading port of the housing 1, the opening of the outer tub 12, and the opening of the inner tub.

[0057] In some embodiments, the outer drum 12 and the inner drum can be arranged coaxially inside and outside. A hole may be provided on the outer wall of the inner drum, allowing water from the outer drum 12 to enter the inner drum through the hole to wash the clothes in the inner drum's clothes handling chamber. Simultaneously, during clothes drying, air from the inner drum's clothes handling chamber can also enter the interior space of the outer drum 12 through the hole.

[0058] In some embodiments, a drive device (not shown in the figure) may be provided inside the housing 1. The drive device may be located outside the outer drum 12, and the output end of the drive device may extend from the center of the rear end of the outer drum 12 into the interior of the outer drum 12 and be connected to the inner drum for transmission, so as to drive the inner drum to rotate relative to the outer drum 12, thereby washing the clothes in the inner drum.

[0059] like Figure 3 As shown, in some embodiments, the garment handling device may include a rotating shaft 22. The rotating shaft 22 is rotatably mounted on the outer drum 12. One end of the rotating shaft 22 is connected to a drive device, and the other end of the rotating shaft 22 is connected to the inner drum. When the rotating shaft 22 rotates, it can drive the inner drum to rotate.

[0060] like Figure 2 As shown, in some embodiments, the garment handling device may include a connecting arm 13. The connecting arm 13 may be disposed on the inner drum, and the connecting arm 13 may be connected to a rotating shaft 22, which may drive the connecting arm 13 and the inner drum to rotate synchronously.

[0061] In some embodiments, the garment handling apparatus may include a bearing assembly 2. The bearing assembly 2 may be disposed on the back side of the outer cylinder 12. The bearing assembly 2 may be used to support the rotating shaft 22.

[0062] like Figure 3As shown, in some embodiments, the bearing assembly 2 may include a bearing seat 21. The bearing seat 21 may be disposed on the rear wall of the outer cylinder 12. The bearing seat 21 may have a mounting through hole 201. The mounting through hole 201 may extend through both the front and rear ends of the bearing seat 21. The rotating shaft 22 may pass through the mounting through hole 201. The bearing seat 21 may be fixedly disposed on the back side of the outer cylinder 12 and used to support the rotating shaft 22. The rotating shaft 22 is rotatably disposed within the mounting through hole 201, and under the drive of the driving device, the rotating shaft 22 may rotate relative to the bearing seat 21 to drive the inner cylinder to rotate.

[0063] In some embodiments, a mounting hole (not shown) may be provided at the center of the rear side of the outer cylinder 12. The bearing seat 21 may be installed in the mounting hole. In this way, the bearing seat 21 can be fixed at the center of the outer cylinder 12.

[0064] like Figure 1 As shown, in some embodiments, the bearing housing 21 may be provided with a connecting hole 203, which can be used to fit with the outer cylinder 12 and can be used for connecting parts to pass through, so as to fix the bearing housing 21 at the center of the outer cylinder 12.

[0065] Figure 4 for Figure 3 Exploded cross-sectional view of the bearing assembly.

[0066] like Figure 3 and Figure 4 As shown, in some embodiments, a first bearing 23 may be provided on the bearing housing 21. The first bearing 23 may be installed in the mounting through hole 201, and the first bearing 23 may be sleeved on the rotating shaft 22. Specifically, the inner ring of the first bearing 23 is sleeved on the surface of the rotating shaft 22, and the outer ring of the first bearing 23 is nested in the hole wall of the mounting through hole 201. The first bearing 23 can be used to support the rotating shaft 22 and reduce wear between the rotating shaft 22 and the bearing housing 21.

[0067] like Figure 4 As shown, in some embodiments, the bearing assembly 2 includes an oil seal 25. The oil seal 25 may be located at the front end of the first bearing 23 to seal the connection between the outer cylinder 12 and the bearing housing 21. By providing an oil seal 25 at the front end of the first bearing 23, impurities such as dust, fiber debris, and moisture from the outer cylinder 12 and inner cylinder can be prevented from entering the bearing housing 21 to a greater extent.

[0068] like Figure 3 and Figure 4As shown, in some embodiments, the bearing seat 21 can be provided with a second bearing 24. The second bearing 24 can be arranged in the mounting through hole 201. The second bearing 24 can be sleeved on the rotating shaft 22, and the second bearing 24 can be arranged at the rear side of the first bearing 23 at intervals. Specifically, the inner ring of the second bearing 24 is sleeved on the surface of the rotating shaft 22, and the outer ring of the second bearing 24 is nested in the hole wall of the mounting through hole 201. Moreover, the first bearing 23 and the second bearing 24 are arranged at intervals on the rotating shaft 22, which can improve the stability of the support of the rotating shaft 22.

[0069] As shown, Figure 3 in some embodiments, the inner wall of the mounting through hole 201, the outer surface of the rotating shaft 22, the first bearing 23 and the second bearing 24 are closed to form a gas space 202; the bearing seat 21 is provided with a ventilation hole 204, one end of the ventilation hole 204 communicates with the gas space 202, and the other end of the ventilation hole 204 communicates with the outside.

[0070] It should be noted that due to the fact that part of the water vapor still enters the gas space 202 through the side of the first bearing 23 during washing, drying and other working processes, it is difficult to discharge this part of water vapor, and long-term accumulation in the bearing seat 21 is easy to cause rusting and damage of the first bearing 23 and the second bearing 24, noise and the like.

[0071] As shown, Figure 3 and Figure 4 in the present application, by providing the bearing seat 21 with the ventilation hole 204, one end of the ventilation hole 204 communicates with the first bearing 23 and the second bearing 24, and the other end of the ventilation hole 204 communicates with the outside, thereby providing a channel for the water vapor accumulated in the gas space 202 to discharge from the bearing seat 21, and the water vapor can be discharged to the outside of the bearing seat 21 through the ventilation hole 204, thereby effectively reducing the risk of water vapor accumulation in the bearing seat 21, and avoiding rusting and damage of the first bearing 23 and the second bearing 24 due to long-term contact with water vapor.

[0072] Specifically, during the operation of the clothes treatment equipment, with the high-speed rotation of the rotating shaft 22 and the change of the temperature difference between the inside and outside, the water vapor in the gas space 202 will produce convection or form a pressure difference, and the water vapor can be discharged to the outside through the ventilation hole 204. Further, for example, during the process of alternating washing and dewatering stages of the clothes treatment equipment, periodic air pressure fluctuations will occur. At some moments, due to the acceleration, deceleration of the rotating shaft 22 or the tumbling of the clothes in the drum, the air pressure in the bearing seat 21 will appear to be temporarily increased. When the air pressure is increased, the water vapor in the gas space 202 will be more strongly pressed towards the ventilation hole 204, and discharged to the outside through the ventilation hole 204.

[0073] Figure 5 For Figure 4A schematic view of the back surface of the middle bearing seat; Figure 6 To Figure 5 a schematic view of the back surface of the middle bearing seat.

[0074] As Figure 3 and Figure 5 shown, in some embodiments, the back end surface of the bearing seat 21 can be exposed to the back surface of the outer cylinder 12. The end of the vent hole 204 away from the gas space 202 is arranged at the back end surface of the bearing seat 21 and is exposed to the back surface of the outer cylinder 12.

[0075] In this way, by exposing the back end surface of the bearing seat 21 to the back surface of the outer cylinder 12, that is, the back end of the bearing seat 21 is not closed by the outer cylinder 12, and the end of the vent hole 204 away from the gas space 202 is arranged at the back end surface of the bearing seat 21, that is, the vent hole 204 penetrates through the back end of the bearing seat 21, and at the same time, the vent hole 204 is also exposed to the back surface of the outer cylinder 12, so that the vent hole 204 can be in communication with the outside, and water vapor can be more smoothly discharged from the inside of the bearing seat 21 to the outside through the vent hole 204.

[0076] As Figure 5 and Figure 6 shown, in some embodiments, the vent hole 204 can include a first vent hole 2041. The first vent hole 2041 can be located below the bottom of the gas space 202. The first vent hole 2041 can be in communication with the bottom region of the gas space 202. Since the liquid water accumulated in the gas space 202 of the bearing seat 21 is prone to accumulate in the bottom region of the gas space 202 under the action of gravity, by arranging the first vent hole 2041 below the bottom of the gas space 202, the first vent hole 2041 is used to communicate the bottom region of the gas space 202 with the outside, so that water can be more efficiently discharged from the gas space 202, improving the efficiency of water discharge and reducing the residence time of water in the bearing seat 21. In this way, it helps to reduce the risk of rusting and damage of the first bearing 23 and the second bearing 24 due to long-term contact with water, and also reduces the noise and vibration generated during the working rotation of the rotating shaft 22, improving the stability and durability of the clothes treatment equipment.

[0077] As Figure 4 shown, in some embodiments, the first vent hole 2041 can be arranged to extend along the axial direction of the bearing seat 21. The back end of the first vent hole 2041 can penetrate through the back end surface of the bearing seat 21. The front end of the first vent hole 2041 can be in communication with the bottom region of the gas space 202.

[0078] Specifically, the first vent hole 2041 is arranged at the bottom outer side of the gas space 202. The first vent hole 2041 is arranged in an axial extension direction of the bearing seat 21, and the extension direction of the first vent hole 2041 is consistent with the axial direction of the bearing seat 21 and the rotating shaft 22. The rear end of the first vent hole 2041 penetrates the rear end surface of the bearing seat 21, so as to be in communication with the outside. The front end of the first vent hole 2041 is in direct communication with the bottom region of the gas space 202. The axial extension arrangement of the first vent hole 2041 enables the water vapor to be discharged more directly and efficiently through the hole, thereby reducing the residence time of the water vapor in the bearing seat 21 and further reducing the risk of rusting and damage of the bearing.

[0079] In other embodiments, the first vent hole 2041 can be arranged in an inclined downward extension direction along the bearing seat 21 from front to rear. In the inclined downward extension direction of the hole, the liquid water can be quickly discharged.

[0080] Figure 7 For Figure 5 the front side view; Figure 8 For Figure 7 the cross-sectional view; Figure 9 For Figure 3 the enlarged view of part A; Figure 10 For Figure 7 the enlarged view of part B.

[0081] As Figure 7 and Figure 8 shown, in some embodiments, the hole wall at the bottom of the gas space 202 can be provided with a first vent groove 205. The upper end of the first vent groove 205 can be in communication with the gas space 202. The lower end of the first vent groove 205 can be in communication with the end of the first vent hole 2041 close to the gas space 202. By providing the first vent groove 205 on the hole wall at the bottom of the gas space 202, the first vent groove 205 can communicate the gas space 202 with the first vent hole 2041. Moreover, under the action of gravity, the liquid water can directly deposit on the hole wall at the bottom of the gas space 202 and can be directly discharged out of the bearing seat 21 through the first vent groove 205 and the first vent hole 2041.

[0082] Specifically, the upper end of the first vent groove 205 is in communication with the gas space 202, so that the water vapor in the gas space 202 can enter the first vent groove 205. The lower end of the first vent groove 205 is in communication with the end of the first vent hole 2041 close to the gas space 202, so that the water vapor can smoothly enter the first vent hole 2041 from the vent groove and be discharged to the outside.

[0083] In some embodiments, the first vent groove 205 can be arranged on the hole wall of the mounting through hole 201 at any position between the first bearing 23 and the second bearing 24.

[0084] As shown in Figure 7 some embodiments, the bearing seat 21 can be provided with a first mounting position 211. The first mounting position 211 can be arranged at the front side of the gas space 202. The first bearing 23 can be mounted on the first mounting position 211. Specifically, the inner hole wall of the mounting through hole 201 can be protruded or recessed to form the first mounting position 211, so that one end of the first bearing 23 can abut against the inner hole wall of the mounting through hole 201, thereby being limited in the bearing seat 21.

[0085] As shown in Figure 6 some embodiments, the bearing seat 21 can be provided with a second mounting position 212. The second mounting position 212 can be arranged at the rear side of the gas space 202. The second bearing 24 can be mounted on the second mounting position 212. Specifically, the inner hole wall of the mounting through hole 201 can be protruded or recessed to form the second mounting position 212, so that one end of the second bearing 24 can abut against the inner hole wall of the mounting through hole 201, thereby being limited in the bearing seat 21, improving the installation stability of the second bearing 24, and the fixing structure is simple.

[0086] As shown in Figure 9 and Figure 10 some embodiments, the first ventilation groove 205 can be arranged at the front end of the first ventilation hole 2041. The first ventilation groove 205 can be opened from the rear side wall of the first mounting position 211 towards the gas space 202. Wherein, by arranging the first ventilation groove 205 at the front end of the first ventilation hole 2041, the first ventilation groove 205 can be in communication with the bottom of the gas space 202 and close to the front side area, that is, the first ventilation groove 205 is arranged at the position close to the outer cylinder 12 side of the gas space 202, thereby facilitating the water entering the gas space 202 through the outer cylinder 12 or the inner cylinder at the beginning to pass through the first ventilation groove 205 more quickly and efficiently, and facilitating the water in the gas space 202 to be discharged outside the bearing seat 21. On the other hand, since the rear end of the first bearing 23 abuts against the rear side wall of the first mounting position 211, by recessing the first ventilation groove 205 from the rear side wall of the first mounting position 211 towards the gas space 202, the design process of the bearing seat 21 can be simplified, and the manufacturing cost is reduced and the manufacturing process is simplified by avoiding punching at other positions of the gas space 202 in the bearing seat 21.

[0087] As shown in Figure 4 and Figure 5As shown, in some embodiments, the vent hole 204 can include a second vent hole 2042. The second vent hole 2042 can be located above the top of the gas space 202. The second vent hole 2042 can be in communication with the bottom region of the gas space 202. Since the liquid water in the gas space 202 can evaporate to form water vapor, by arranging the second vent hole 2042 above the top of the gas space 202, the second vent hole 2042 is used to communicate the top region of the gas space 202 with the outside, so that the water vapor accumulated at the top of the gas space 202 can be more efficiently discharged from the gas space 202, thereby reducing the residence time of the water vapor inside the bearing seat 21. In this way, it helps to reduce the risk of rusting and damaging the first bearing 23 and the second bearing 24 due to long-term contact with water vapor, and also reduces the noise and vibration generated during the operation of the rotating shaft 22, thereby improving the stability and durability of the laundry treating apparatus.

[0088] As shown in FIG. 1, the laundry treating apparatus 1 can include a cabinet 10, a drum 20, a rotating shaft 22, a bearing seat 21, a first bearing 23, a second bearing 24, a vent hole 204, and a gas space 202. Figure 4 and Figure 5 As shown, in some embodiments, the vent hole 204 can include a first vent hole 2041 and a second vent hole 2042. The first vent hole 2041 is located below the bottom of the gas space 202, and the second vent hole 2042 is located above the top of the gas space 202. The first vent hole 2041 and the second vent hole 2042 provide different exhaust paths for the liquid water and the vapor in the gas space 202, respectively. Specifically, the liquid water can be discharged to the outside of the bearing seat 21 through the first vent hole 2041, the water vapor can be discharged to the outside of the bearing seat 21 through the second vent hole 2042, or through the top and bottom at the same time, which can more effectively reduce the accumulation of water vapor in the gas space 202.

[0089] Further, the arrangement of the second vent hole 2042 can promote natural convection in the gas space 202. As hot air rises and cold wet air sinks, the second vent hole 2042 can capture and discharge the hot wet air at the top, while the first vent hole 2041 handles the cold wet air at the bottom, thereby forming a cycle and improving the efficiency of water vapor discharge.

[0090] As shown in FIG. 1, the laundry treating apparatus 1 can include a cabinet 10, a drum 20, a rotating shaft 22, a bearing seat 21, a first bearing 23, a second bearing 24, a vent hole 204, and a gas space 202. Figure 8 As shown, in some embodiments, the second vent hole 2042 can be arranged along the axial direction of the bearing seat 21. The rear end of the second vent hole 2042 can penetrate the rear end face of the bearing seat 21, and the front end of the second vent hole 2042 can be in communication with the top region of the gas space 202.

[0091] Specifically, the second vent hole 2042 is arranged on the top outer side of the gas space 202. The second vent hole 2042 is arranged in an axial extension along the bearing seat 21, and the extension direction of the second vent hole 2042 is consistent with the axial direction of the bearing seat 21 and the rotating shaft 22. The rear end of the second vent hole 2042 penetrates the rear end surface of the bearing seat 21, so as to be in communication with the outside. The front end of the second vent hole 2042 is in direct communication with the top region of the gas space 202. The axial extension of the second vent hole 2042 enables the water vapor to be discharged more directly and efficiently through the channel, thereby reducing the residence time of the water vapor in the bearing seat 21 and further reducing the risk of rusting and damage of the bearing.

[0093] As Figure 11 , Figure 12 shown, in some embodiments, the hole wall on the top of the gas space 202 can be provided with a second vent groove 206. The lower end of the second vent groove 206 can be in communication with the gas space 202. The upper end of the second vent groove 206 can be in communication with one end of the second vent hole 2042 close to the gas space 202. By providing the second vent groove 206 on the hole wall on the top of the gas space 202, the second vent groove 206 can communicate the gas space 202 with the second vent hole 2042. Moreover, since the water vapor is usually gathered on the top of the gas space 202, the water vapor can be directly discharged out of the bearing seat 21 through the second vent groove 206 on the top and the second vent hole 2042.

[0094] Specifically, the lower end of the second vent groove 206 is in communication with the gas space 202, so that the water vapor in the gas space 202 can enter the second vent groove 206. The upper end of the second vent groove 206 is in communication with one end of the second vent hole 2042 close to the gas space 202, so that the water vapor can smoothly enter the second vent hole 2042 from the second vent groove 206 and be discharged to the outside.

[0095] In some embodiments, the second vent groove 206 can be arranged on the hole wall of the mounting through hole 201 at any position between the first bearing 23 and the second bearing 24.

[0096] As Figure 12 and Figure 13 shown, in some embodiments, the second vent groove 206 can be arranged at the front end of the second vent hole 2042. The second vent groove 206 can be opened by the rear side wall of the first mounting position 211 towards the gas space 202.

[0097] The second vent groove 206 is arranged at the front end of the second vent hole 2042, so that the second vent groove 206 can be in communication with the top of the gas space 202 near the front side region, i.e. the second vent groove 206 is arranged at the position of the gas space 202 near the outer cylinder 12 side, thereby facilitating the water vapor entering the gas space 202 through the outer cylinder 12 or the inner cylinder at the beginning to pass through the second vent groove 206 more quickly and efficiently, and facilitating the realization of the water vapor in the gas space 202 being discharged to the outside of the bearing seat 21. On the other hand, since the rear end of the first bearing 23 abuts against the rear side wall of the first mounting position 211, by arranging the second vent groove 206 on the rear side wall of the first mounting position 211 towards the direction of the gas space 202, the design process of the bearing seat 21 can be simplified, and the bearing seat 21 is avoided to be punched at other positions of the gas space 202, thereby reducing the manufacturing cost and simplifying the manufacturing process.

[0098] As shown in FIG. 1, in some embodiments, the first vent groove 205 and the second vent groove 206 can be symmetrically arranged on the upper and lower sides of the first mounting position 211. Figure 8

[0099] In other embodiments, the bearing seat 21 can be provided with a third vent hole (not shown in the figure). The number of the third vent holes can be multiple. The multiple third vent holes can be arranged at intervals along the circumference of the mounting through hole 201 of the bearing seat 21.
