Description

Technical Field

[0001] The present invention relates to the field of household appliance technology, and in particular to an inner drum structure and a clothing processing device. Background Technology

[0002] Clothing handling devices, such as washing machines, include an outer casing, an inner drum housed within the casing, and a drain pump. The drain pump removes water from the inner drum to the outside of the washing machine, resulting in high energy consumption. Summary of the Invention

[0003] To solve the above-mentioned technical problems, or at least partially solve them, embodiments of the present invention provide an inner cylinder structure for a clothing processing device and a clothing processing device.

[0004] In a first aspect, embodiments of the present invention provide an inner cylinder structure for a garment processing device, including an inner cylinder, a water guiding structure, and a main shaft assembly for driving the inner cylinder to rotate; the water guiding structure is located in the inner cavity of the inner cylinder, the water guiding structure has a water guiding channel communicating with the inner cavity of the inner cylinder, and the outlet of the water guiding channel is connected to a water outlet shaft; the main shaft assembly has a hollow rotating shaft, the water outlet shaft passes through the rear cover of the inner cylinder and is disposed in the rotating shaft, and the main shaft assembly can rotate relative to the water outlet shaft, so that water in the inner cavity of the inner cylinder is discharged to the outside of the garment processing device in sequence through the water guiding channel and the water outlet shaft.

[0005] The inner drum structure of the garment processing device provided in this embodiment of the invention features a water-guiding structure within its inner cavity. This water-guiding structure has a water-guiding channel communicating with the inner cavity of the inner drum, and the outlet of the water-guiding channel is connected to a water-outlet shaft. Specifically, the inlet of the water-guiding channel communicates with the inner cavity of the inner drum, and the outlet of the water-guiding channel communicates with the water-outlet shaft. The water-outlet shaft passes through the rear cover of the inner drum and is housed in a hollow rotating shaft of the main shaft assembly used to drive the inner drum's rotation. The water-outlet shaft does not rotate. Therefore, during drainage or spin-drying, as the inner drum rotates, the water in the inner cavity of the inner drum is discharged to the outside of the garment processing device sequentially through the water-guiding channel and the water-outlet shaft under the action of centrifugal force. In other words, the inner drum structure of the garment processing device provided in this embodiment of the invention directly discharges water to the outside of the garment processing device through the guidance of the water-guiding structure, eliminating the need for external driving force and saving energy. Furthermore, by housing the water-outlet shaft in a hollow rotating shaft, the structure of the main shaft assembly is effectively utilized, saving space to a certain extent.

[0006] Optionally, the inlet of the water guiding channel is located near the radial outer edge of the inner cavity of the inner cylinder.

[0007] During drainage, the water is thrown towards the radial outer edge of the inner cylinder under the action of centrifugal force and rotates with the water collection chamber. By setting the inlet of the water guide channel close to the radial outer edge of the inner cylinder, the drainage path is shortened. Under the action of centrifugal force, the rotating water can quickly enter the water guide channel from the inlet, further improving the drainage efficiency.

[0008] Optionally, the inlet of the water guide channel faces the rotation direction of the inner cylinder.

[0009] During drainage or dehydration, the water is thrown towards the radial outer edge of the inner cylinder under the action of centrifugal force and rotates with the inner cylinder. The inlet of the water guiding channel faces the rotation direction of the inner cylinder. In other words, the inlet of the water guiding channel is opposite to the rotation direction of the water in the inner cylinder, which further shortens the drainage path and improves drainage efficiency.

[0010] Optionally, the water guiding structure includes a water guiding part and an installation part; the water guiding part is provided with the water guiding channel, the installation part is located at the outlet of the water guiding channel, and the water outlet shaft is connected to the installation part.

[0011] The water guiding section is stably fixed to the water outlet shaft by the mounting part, so that the water guiding structure remains stationary when the inner drum rotates relative to the water outlet shaft. That is, the water guiding structure will not shift during drainage or spin-drying, allowing water to quickly enter the water guiding channel and be discharged under the action of centrifugal force, shortening the drainage path and improving drainage efficiency. At the same time, connecting the water guiding structure and the water outlet shaft by the mounting part also enhances the connection strength and structural stability between the water guiding structure and the water outlet shaft, which helps to extend the service life of the inner drum structure of the garment processing device.

[0012] Optionally, the water guiding portion includes a hollow water guiding plate extending radially along the inner cylinder, the inner cavity of the water guiding plate forming the water guiding channel.

[0013] During drainage or dehydration, the water in the inner cavity of the inner cylinder is thrown towards the radial outer edge of the inner cylinder under the action of centrifugal force and rotates with the inner cylinder, extending the water guide plate radially along the inner cylinder. That is, extending the water guide plate towards the water flow under the action of centrifugal force, which shortens the drainage path to a certain extent. This allows the water flow under the action of centrifugal force to quickly enter the water guide channel and be discharged through the water outlet shaft, further improving the drainage efficiency. At the same time, the structure is simple, easy to manufacture, and easy to assemble.

[0014] Optionally, the water guide plate is also provided with a first reinforcing rib.

[0015] This design improves the structural strength of the water guide plate, thereby enhancing the stability of the water guide structure in water flow under centrifugal force to a certain extent.

[0016] Optionally, the mounting part includes a mounting ring, and the outlet of the water guiding channel is located within the area enclosed by the mounting ring; one end of the water outlet shaft near the water guiding structure is sleeved on the mounting ring.

[0017] This design is simple and easy to assemble. Furthermore, since the outlet of the water guide channel is located within the area enclosed by the mounting ring, the strength of the water guide structure at its outlet is increased to some extent, further improving the structure's resistance to impact from centrifugal force.

[0018] Optionally, the mounting ring is provided with a first pre-positioning part, and the water outlet shaft is provided with a second pre-positioning part that cooperates with the first pre-positioning part.

[0019] With this configuration, during assembly, the water outlet shaft can be pre-positioned on the mounting ring using the first and second pre-positioning parts, which facilitates assembly and improves assembly accuracy and efficiency.

[0020] Optionally, the mounting ring is provided with a first connecting part, and the water outlet shaft is provided with a second connecting part that matches the first connecting part.

[0021] Optionally, a second reinforcing rib is also provided on the outer side of the mounting ring.

[0022] A second reinforcing rib is set on the outside of the mounting ring, which further improves the structural strength of the water guide plate, especially the structural strength of the water guide structure at the outlet of the water guide channel. This enhances the water guide structure's resistance to impact from centrifugal force, resulting in high safety and reliability.

[0023] Optionally, the second reinforcing rib is a reinforcing ring surrounding the outside of the mounting ring.

[0024] Optionally, the inlet of the water guiding channel is located above the central axis of the water outlet shaft; the height of the inlet of the water guiding channel is higher than the height of the outlet of the water guiding channel, and the height of the water guiding channel decreases sequentially along the direction from the inlet to the outlet of the water guiding channel.

[0025] With this design, the water in the inner cylinder can be smoothly discharged after entering the water guiding channel under the action of centrifugal force, further improving drainage efficiency.

[0026] Optionally, there are at least two water guiding structures, which are arranged at intervals along the circumference of the inner cylinder, and the outlet of the water guiding channel of each water guiding structure is connected to the water outlet shaft.

[0027] The design incorporates multiple water-guiding structures, which further reduces drainage time and improves drainage efficiency, thereby shortening washing time and further reducing energy consumption.

[0028] Optionally, the inlet of the water guiding channel of at least one of the water guiding structures is located in an axial direction in the inner cylinder at a different position than the inlet of the water guiding channels of the other water guiding structures in an axial direction in the inner cylinder.

[0029] With this configuration, when multiple water guiding structures are installed in the inner cavity of the inner cylinder, at least one water guiding structure will be located at a different position than the others along the axial direction of the inner cylinder. That is, the water guiding structures are staggered along the axial direction of the inner cylinder, which further improves drainage efficiency and enhances the user experience.

[0030] Optionally, a bearing is provided between the water outlet shaft and the rotating shaft, with the inner ring of the bearing fixed relative to the outer wall of the water outlet shaft and the outer ring of the bearing fixed relative to the inner wall of the rotating shaft, so that the main shaft assembly can rotate around the water outlet shaft.

[0031] This design is simple and easy to assemble.

[0032] Optionally, a partition is also provided in the inner cavity of the inner tube, which divides the inner cavity of the inner tube into a clothing processing cavity and a drainage cavity. The partition is provided with a drainage hole for connecting the clothing processing cavity and the drainage cavity, and the water guiding structure is located in the drainage cavity.

[0033] The inner drum is divided into a laundry handling chamber and a drain chamber by a partition. The water guiding structure is located in the drain chamber. In other words, the partition separates the water guiding structure from the laundry. This design effectively prevents the laundry from getting tangled in the water guiding structure, thus providing effective protection for both the laundry and the water guiding structure to a certain extent. This ensures good safety and improves user satisfaction.

[0034] Optionally, the partition is positioned close to the rear cover.

[0035] By setting it up this way, the volume of the clothes handling chamber is increased as much as possible without changing the overall outer contour dimensions of the inner drum structure, thereby increasing the washing capacity of the inner drum and helping to develop clothes handling devices towards larger capacity.

[0036] Optionally, there are multiple drainage holes, which are spaced apart circumferentially along the partition.

[0037] Multiple drainage holes are spaced around the partition, which saves drainage time, improves drainage efficiency, shortens washing time, and enhances user satisfaction.

[0038] Optionally, the drain hole is located near the radial edge of the partition.

[0039] During drainage, water is thrown towards the radial outer edge of the inner cylinder under the action of centrifugal force and rotates with the inner cylinder. By setting the drain hole close to the radial outer edge of the partition, the drainage path is shortened, allowing water to quickly enter the drainage chamber and drainage channel from the drain hole under the action of centrifugal force and be discharged, further improving drainage efficiency.

[0040] Secondly, embodiments of the present invention also provide a garment processing device, including a housing and an inner cylinder structure of the garment processing device as described above, located within the housing. Attached Figure Description

[0052] To better understand the above-mentioned objectives, features, and advantages of the embodiments of the present invention, the solutions of the embodiments of the present invention will be further described below. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0053] Many specific details are set forth in the following description in order to provide a full understanding of the embodiments of the present invention, but the embodiments of the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the embodiments of the present invention, and not all embodiments.

[0054] A front-loading washing machine typically includes an inner drum and an outer drum located outside the inner drum. The outer drum is sealed to hold water, while the inner drum holds the clothes to be washed. The inner drum can rotate around a pivot relative to the outer drum, thereby tumbling and washing the clothes inside the inner drum.

[0055] The radial outer edge of the inner cylinder, i.e. the side wall, has multiple water passage holes that connect the inner cylinder and the outer cylinder.

[0056] However, in existing technologies, water in the inner drum needs to be drained to the outside of the washing machine through a drain pump, which consumes a lot of energy.

[0057] The inner cylinder structure and the garment processing device of this invention will be explained and described in detail below through specific embodiments:

[0058] Example 1

[0059] refer to Figures 1 to 8 As shown in the figure, this embodiment provides an inner drum structure for a clothing processing device (hereinafter referred to as the inner drum structure), wherein the clothing processing device may be, for example, a drum washing machine, a clothes dryer, etc.

[0060] The inner cylinder structure includes an inner cylinder 1, a water guiding structure 2, and a main shaft assembly 4 for driving the inner cylinder 1 to rotate. The water guiding structure 2 is located in the inner cavity of the inner cylinder 1 and has a water guiding channel communicating with the inner cavity of the inner cylinder 1. The outlet 213 of the water guiding channel is connected to a water outlet shaft 3. The main shaft assembly 4 has a hollow rotating shaft 42. The water outlet shaft 3 passes through the rear cover 12 of the inner cylinder 1 and is installed in the hollow rotating shaft 42. The main shaft assembly 4 can rotate relative to the water outlet shaft 3 so that the water in the inner cavity of the inner cylinder 1 is discharged to the outside of the clothing treatment device in sequence through the water guiding channel and the water outlet shaft 3.

[0061] The water guiding structure 2 is located inside the inner cavity of the inner cylinder 1. The water guiding structure 2 has a water guiding channel and an inlet 212 and an outlet 213 connected to the water guiding channel. It can be understood that the inlet 212 of the water guiding structure 2 is the same as the inlet 212 of the water guiding channel, and the outlet 213 of the water guiding structure 2 is the same as the outlet 213 of the water guiding channel. The inlet 212 of the water guiding channel is connected to the inner cavity of the inner cylinder 1, and the outlet 213 of the water guiding channel is connected to the water outlet shaft 3. That is, the water outlet shaft 3 is connected to the inner cavity of the inner cylinder 1 through the water guiding channel of the water guiding structure 2. Therefore, when the inner cylinder 1 rotates at medium to high speed relative to the water outlet shaft 3 and the water guiding structure 2 to drain or dehydrate, the water guiding structure 2 and the water outlet shaft 3 have a guiding effect on the water in the inner cavity of the inner cylinder 1.

[0062] In addition, the water outlet shaft 3 is inserted into the hollow rotating shaft 42, and the end of the water outlet shaft 3 away from the water guiding structure 2 can extend to the outside of the rotating shaft 42, that is, the end of the water outlet shaft 3 away from the water guiding structure 2 is located outside the rotating shaft 42. Of course, the end of the water outlet shaft 3 away from the water guiding structure 2 can be covered in the hollow cavity of the rotating shaft 42. In this case, the water in the inner cavity of the inner cylinder 1 is discharged sequentially through the water guiding channel, the water outlet shaft 3, and the hollow cavity of the rotating shaft 42 under the action of centrifugal force.

[0063] Furthermore, the end of the water outlet shaft 3 furthest from the water guiding structure 2 is used to connect with the outside. In specific implementation, the end of the water outlet shaft 3 furthest from the water guiding structure 2 can be connected to the outside, such as a floor drain, through a drain pipe. Of course, the end of the water outlet shaft 3 furthest from the water guiding structure 2 can also be directly connected to the outside. It can be arbitrarily selected according to the specific use case, and no further restrictions are imposed here.

[0064] It should be noted that the water guiding structure 2 does not contact the inner wall of the inner cylinder 1 and will not interfere with the rotation of the inner cylinder 1 around the main shaft assembly 4.

[0065] During drainage or spin-drying, the inner drum 1 rotates at medium to high speed, while the water guiding structure 2 remains stationary. This means the inner drum 1 can rotate relative to the water guiding structure 2. Water in the inner cavity of the inner drum 1 is thrown towards the radial outer edge of the inner drum 1 under centrifugal force, rotating at high speed, and then enters the water guiding channel and outlet shaft 3 through the inlet 212 of the water guiding channel before being discharged to the outside of the garment processing device. In other words, the inner drum structure provided in this embodiment, by setting the water guiding structure 2 and outlet shaft 3 within the inner cavity of the inner drum 1, connects the inlet 212 of the water guiding channel of the water guiding structure 2 to the inner cavity of the inner drum 1, and the outlet 213 of the water guiding channel to the outlet shaft 3. This eliminates the need for external driving force. During spin-drying or drainage, the water in the inner drum 1 is discharged sequentially through the water guiding channel and outlet shaft 3 under centrifugal force, saving energy. Simultaneously, since no external driving force is required, costs are reduced to a certain extent.

[0066] Definition: The end of the inner drum 1 used for taking out and putting in laundry is the front end of the inner drum 1, that is, the end of the inner drum 1 facing the user is the front end of the inner drum 1, and the other side opposite to the front side of the inner drum 1 is the rear end of the inner drum 1, that is, the end of the inner drum 1 away from the user is the rear end of the inner drum 1.

[0067] In a specific implementation, the main shaft assembly 4 is located outside the rear end of the inner cylinder 1. The main shaft assembly 4 includes a support 41 and the hollow rotating shaft 42 mentioned above. The rotating shaft 42 is coaxially disposed at the center of the support 41 and is fixed relative to the support 41. The rotating shaft 42 extends in a direction away from the inner cylinder 1, and the inner cylinder 1 is coaxially disposed on the support 41.

[0068] refer to Figure 1 As shown, the support base 41 is provided with at least two first mounting holes 411, the rear cover 12 is provided with at least two second mounting holes 121, and the inner cylinder 1 is provided with at least two third mounting holes 111. The first mounting holes 411, the second mounting holes 121, and the third mounting holes 111 correspond one-to-one. The support base 41, the rear cover 12, and the inner cylinder 1 are detachably connected by fasteners passing through the first mounting holes 411, the corresponding second mounting holes 121, and the corresponding third mounting holes 111.

[0069] Of course, the support seat 41 can also be directly welded to the rear end of the inner cylinder 1.

[0070] In practice, the support frame is located on the outside of the inner cylinder 1, and the rotating shaft 42 is rotatably connected to the support frame.

[0071] The garment handling device is also equipped with a drive structure, such as a motor, for driving the rotating shaft 42 to rotate. The motor is located on the outside of the inner drum 1, and the drive shaft of the motor is connected to the rotating shaft 42 through a drive belt. Thus, the motor can drive the rotating shaft 42 to rotate. Since the inner drum 1 and the rotating shaft 42 assembly are relatively fixed, the rotation of the rotating shaft 42 can drive the inner drum 1 to rotate.

[0072] The support base and the rotating shaft 42 can be integrally formed. The rotating shaft 42 can drive the support base and the inner cylinder 1 fixed on the support base to rotate together. (Reference) Figure 5 As shown, when the end of the rotating shaft 42 near the water guiding structure 2 is covered in the support, the support has a clearance hole through which the water outlet shaft 3 passes and extends into the rotating shaft 42. A part of the water outlet shaft 3 passes through the clearance hole of the support. A bearing 5 is also provided between the water outlet shaft 3 and the support. The inner ring of the bearing 5 is interference-fitted with the water outlet shaft 3, and the outer ring of the bearing 5 is interference-fitted with the inner wall of the clearance hole, so as to facilitate the rotation of the main shaft assembly 4 around the water outlet shaft 3.

[0073] It should be noted that the clothing processing device provided in this embodiment does not have an outer cylinder. A water guiding structure 2 is provided in the inner cavity of the inner cylinder 1. The water guiding structure 2 has a water guiding channel that communicates with the inner cylinder of the inner cylinder 1. A water outlet shaft 3 is connected at the outlet 213 of the water guiding channel. The water outlet shaft is inserted into the hollow rotating shaft 42 of the main shaft assembly used to drive the inner cylinder 1 to rotate. Water is directly guided to the outside of the clothing processing device through the water guiding structure 2 and the water outlet shaft 3. No external driving force is required, which saves energy and cost.

[0074] The inner drum structure of the garment processing device provided in this embodiment features a water guiding structure 2 within the inner cavity of the inner drum 1. The water guiding structure 2 has a water guiding channel communicating with the inner cavity of the inner drum 1, and the outlet 213 of the water guiding channel is connected to a water outlet shaft 3. Specifically, the inlet 212 of the water guiding channel communicates with the inner cavity of the inner drum 1, and the outlet 213 of the water guiding channel communicates with the water outlet shaft 3. The water outlet shaft 3 extends from the rear cover 12 of the inner drum 1 and passes through the hollow rotating shaft 42 of the main shaft assembly 4 used to drive the rotation of the inner drum 1. The water outlet shaft 3 does not rotate. Therefore, during drainage or spin-drying, as the inner drum 1 rotates, the water in the inner cavity of the inner drum 1 is discharged to the outside of the garment processing device through the water guiding channel of the water guiding structure 2 and the water outlet shaft 3 under the action of centrifugal force. In other words, the inner drum structure provided in this embodiment directly discharges water to the outside of the garment processing device through the guidance of the water guiding structure 2, without requiring external driving force, thus saving energy. In addition, by having the water outlet shaft 3 inserted into the hollow rotating shaft, the structure of the main shaft assembly is effectively utilized, saving space to a certain extent.

[0075] In some embodiments, reference Figure 1 and Figure 4 As shown, the inlet 212 of the water guiding channel is located near the radial outer edge of the inner cavity of the inner cylinder 1.

[0076] The inlet 212 of the water guiding channel is located close to the radial outer edge of the inner cavity of the inner cylinder 1. That is, the distance between the inlet 212 of the water guiding channel and the radial outer edge of the inner cylinder 1 is less than the distance between the inlet 212 of the water guiding channel and the rotation axis of the inner cylinder 1.

[0077] During drainage, the water is thrown towards the radial outer edge of the inner cylinder 1 under the action of centrifugal force and rotates together with the water collection cavity. By setting the inlet 212 of the water guiding channel close to the radial outer edge of the inner cylinder 1, the drainage path is shortened. Under the action of centrifugal force, the rotating water can quickly enter the water guiding channel from the inlet 212, which further improves the drainage efficiency.

[0078] In some embodiments, the inlet 212 of the water guide channel faces the rotation direction of the inner cylinder 1.

[0079] During drainage or dehydration, the water is thrown towards the radial outer edge of the inner cylinder 1 under the action of centrifugal force and rotates with the inner cylinder 1. The inlet 212 of the water guiding channel faces the rotation direction of the inner cylinder 1. That is to say, the inlet 212 of the water guiding channel is opposite to the rotation direction of the water in the inner cylinder 1, which further shortens the drainage path and improves the drainage efficiency.

[0080] Of course, the water guiding structure 2 can be provided with multiple inlets 212 at intervals to facilitate the rapid entry of water into the water guiding channel and discharge, which helps to improve drainage efficiency. In specific implementation, all of the multiple inlets 212 can face the rotation direction of the inner cylinder 1, or some of the inlets 212 can face the rotation direction of the inner cylinder 1.

[0081] In some embodiments, reference Figure 5 and Figure 8 As shown, the water guiding structure 2 includes a water guiding part 21 and an installation part 22. The water guiding part 21 is provided with a water guiding channel, and the installation part 22 is located at the outlet 213 of the water guiding channel. The water outlet shaft 3 is connected to the installation part 22. The structure is simple and easy to assemble.

[0082] The water guiding section 21 is stably fixed to the water outlet shaft 3 by the mounting part 22, so that when the inner drum 1 rotates relative to the water outlet shaft 3, the water guiding structure 2 remains stationary. That is, the water guiding structure 2 will not shift during drainage or spin-drying, allowing water to quickly enter the water guiding channel and be discharged under the action of centrifugal force, shortening the drainage path and improving drainage efficiency. At the same time, the mounting part 22 connects the water guiding structure 2 and the water outlet shaft 3 together, which also enhances the connection strength and structural stability between the water guiding structure 2 and the water outlet shaft 3, and helps to improve the service life of the inner drum structure of the garment processing device.

[0083] Further, refer to Figures 6 to 8 As shown, the water guiding part 21 includes a hollow water guiding plate 211 extending radially along the inner cylinder 1, and the inner cavity of the water guiding plate 211 is formed as a water guiding channel.

[0084] During drainage or dehydration, the water in the inner cavity of the inner cylinder 1 is thrown towards the radial outer edge of the inner cylinder 1 under the action of centrifugal force, and rotates with the inner cylinder 1, extending the water guide plate 211 radially along the inner cylinder 1. That is, extending the water guide plate 211 towards the water flow under the action of centrifugal force, which shortens the drainage path to a certain extent, allowing the water flow under the action of centrifugal force to quickly enter the water guide channel and be discharged through the water outlet shaft 3, further improving the drainage efficiency. At the same time, the structure is simple, easy to manufacture, and easy to assemble.

[0085] Among them, reference Figure 6 and Figure 8 As shown, the cross-section of the water guide plate 211 along the radial direction of the inner cylinder 1 can be a fan-shaped structure, that is, the water guide plate 211 is a fan-shaped plate. One end of the fan-shaped plate is fixed on the water outlet shaft 3, and the other end of the fan-shaped plate extends along the radial direction of the inner cylinder 1 towards the side wall of the inner cylinder 1, so that the water flow can enter the water guide channel.

[0086] In some embodiments, as shown in reference 6, the water guide plate 211 is further provided with a first reinforcing rib 61. This design improves the structural strength of the water guide plate 211, thereby improving the stability of the water guide structure 2 in the water flow under centrifugal force to a certain extent.

[0087] In some embodiments, reference Figure 8 As shown, the mounting part 22 includes a mounting ring 221, and the outlet 213 of the water guiding channel is located in the area enclosed by the mounting ring 221; the end of the water outlet shaft 3 near the water guiding structure 2 is sleeved on the mounting ring 221.

[0088] This design is simple, easy to manufacture, and convenient to assemble. Furthermore, since the outlet 213 of the water guiding channel is located within the area enclosed by the mounting ring 221, the strength of the water guiding structure 2 at its outlet 213 is increased to a certain extent, further improving the water guiding structure 2's resistance to impact from centrifugal force.

[0089] In practice, the water outlet shaft 3 can be fitted onto either the outer wall of the mounting ring 221 or the inner wall of the mounting ring 221. It can be set arbitrarily according to the specific usage, and no further restrictions are imposed here.

[0090] In some embodiments, reference Figure 1 and Figure 7 As shown, the mounting ring 221 is provided with a first connecting part 223, and the water outlet shaft 3 is provided with a second connecting part 32 that matches the first connecting part 223. With this design, the water outlet shaft 3 can be assembled on the mounting ring 221 through the matching connection of the first connecting part 223 and the second connecting part 32. The structure is simple, easy to manufacture, and easy to assemble.

[0091] The mounting ring 221 is provided with a plurality of first connecting parts 223 at intervals, and the plurality of first connecting parts 223 are respectively located on both sides of the central axis of the mounting ring 221. Correspondingly, the water outlet shaft 3 is also provided with a plurality of second connecting parts 32, one first connecting part 223 corresponding to one second connecting part 32. The water guide plate 211 is reliably connected to the water outlet shaft 3 through the cooperation of the plurality of first connecting parts 223 and second connecting parts 32.

[0092] In a specific implementation, the first connecting part 223 is a first mounting hole provided on the mounting ring 221, and the second connecting part 32 is a second mounting hole with a fastener (not shown) provided on the water outlet shaft 3.

[0093] For example, the first connecting part 223 is a mounting hole provided on the mounting ring 221, and the mounting hole may have internal threads, for example, and the second connecting part 32 is a mounting bolt provided on the water outlet shaft 3, and the mounting bolt has external threads.

[0094] In other embodiments, the first connecting part 223 may also be directly disposed on the water guide plate 211 and disposed near the outlet 213 of the water guide channel.

[0095] For ease of assembly, please refer to Figure 1 and Figure 7 As shown, the mounting ring 221 is provided with a first prepositioning part 222, and the water outlet shaft 3 is provided with a second prepositioning part 31 that cooperates with the first prepositioning part 222.

[0096] During assembly, the water outlet shaft 3 can be prepositioned on the mounting ring 221 by the first prepositioning part 222 and the second prepositioning part 31, which facilitates assembly and improves assembly accuracy and efficiency.

[0097] When the first prepositioning part 222 and the second prepositioning part 31 are in place, the first mounting hole and the second mounting hole are aligned, and the fastener is inserted into the first mounting hole and the corresponding second mounting hole, so that the water outlet shaft 3 and the mounting ring 221 can be fixed together, and then the water outlet shaft 3 is fixed on the water guide plate 211.

[0098] By setting a first pre-positioning part 222 and a second pre-positioning part 31 between the mounting ring 221 and the water outlet shaft 3 for pre-positioning, on the one hand, the installation efficiency is improved to a certain extent; on the other hand, it can effectively prevent the water outlet shaft 3 from moving around the circumference of the mounting ring 221, thereby improving the connection strength and structural stability and extending the service life.

[0099] In a specific implementation, one of the first pre-positioning portion 222 and the second pre-positioning portion can be an internal spline, and one of the two pre-positioning portions 222 and the second pre-positioning portion can be an external spline. For example, the first pre-positioning portion 222 is an internal spline provided on the inner wall of the mounting ring 221, see reference... Figure 1 As shown, the second prepositioning part 31 is an external spline provided on one end of the water outlet shaft 3 near the water guide structure 2, and the second mounting hole can be opened on the external spline.

[0100] In some embodiments, reference Figures 6 to 8 As shown, a second reinforcing rib 62 is also provided on the outer side of the mounting ring 221.

[0101] A second reinforcing rib 62 is provided on the outside of the mounting ring 221, which further improves the structural strength of the water guide plate 211, especially the structural strength of the water guide structure 2 at the outlet 213 of the water guide channel, thereby enhancing the water guide structure 2's resistance to impact under centrifugal force, resulting in high safety and reliability.

[0102] Furthermore, the second reinforcing rib 62 is a reinforcing ring surrounding the outer side of the mounting ring 221, which has a simple structure and is easy to manufacture. Of course, the second reinforcing rib 62 can also be a reinforcing protrusion, and there can be multiple reinforcing protrusions, which are arranged around the outer side of the mounting ring 221 along the circumference of the mounting ring 221.

[0103] In some embodiments, the inlet 212 of the water guide channel is located above the central axis of the outlet shaft 3, and the height of the inlet 212 of the water guide channel is higher than the height of the outlet 213 of the water guide channel. Furthermore, the height of the water guide channel decreases sequentially along the direction from the inlet 212 to the outlet 213 of the water guide channel. With this design, the water in the inner cylinder 1 can be smoothly discharged after entering the water guide channel under the action of centrifugal force, further improving the drainage efficiency.

[0104] In some embodiments, there are multiple water guiding structures 2, which are spaced apart along the circumference of the inner cylinder 1, and the outlet 213 of the water guiding channel of each water guiding structure 2 is connected to the water outlet shaft 3.

[0105] Multiple water guiding structures 2 are set in the inner cavity of the inner drum 1, that is, multiple drainage channels are constructed between the water guiding structure 2 and the water outlet shaft 3, which further saves drainage time, improves drainage efficiency, shortens washing time, further reduces energy consumption, and helps to improve user satisfaction.

[0106] Of course, when multiple water guiding structures 2 are arranged in the inner cavity of the inner cylinder 1, the position of the inlet 212 of the water guiding channel of at least one of the multiple water guiding structures 2 in the axial direction of the inner cylinder 1 is different from the position of the inlet 212 of the water guiding channel of the other water guiding structures 2 in the axial direction of the inner cylinder 1. That is, the position of the inlet 212 of the water guiding channel in the axial direction of the inner cavity is different from the position of the inlet 212 of the other water guiding channels in the axial direction of the inner cavity. In other words, the water guiding structures 2, i.e., the inlet 212 of the water guiding channel, are staggered along the axial direction of the inner cavity, which further improves the drainage efficiency and enhances the user experience.

[0107] With this configuration, during drainage or dehydration, the water in the inner cavity of the inner cylinder 1 can not only enter the water outlet shaft 3 through multiple drainage channels under the action of centrifugal force, but also enter the water outlet shaft 3 from different positions along the axial direction of the inner cylinder 1, thereby further improving drainage efficiency and enhancing the user experience.

[0108] In some embodiments, reference Figure 1 and Figure 5 As shown, a bearing 5 is provided between the water outlet shaft 3 and the rotating shaft 42. The inner ring of the bearing 5 is fixed relative to the outer wall of the water outlet shaft 3, for example, the inner ring of the bearing 5 is interference-fitted with the outer wall of the water outlet shaft 3; the outer ring of the bearing 5 is fixed relative to the inner wall of the rotating shaft 42, for example, the outer ring of the bearing 5 is interference-fitted with the inner wall of the rotating shaft 42, so that the main shaft assembly 4 can rotate around the water outlet shaft 3.

[0109] The water outlet shaft 3 is fitted inside the rotating shaft 42 via the bearing 5, which saves space, has a reasonable layout, a simple structure, and is easy to assemble.

[0110] In practice, one or more bearings 5 ​​can be installed between the water outlet shaft 3 and the rotating shaft 42. When multiple bearings 5 ​​are installed between the water outlet shaft 3 and the rotating shaft 42, the multiple bearings 5 ​​are spaced apart along the axial direction of the rotating shaft 42.

[0111] In some embodiments, reference Figure 1 As shown, a partition 14 is also provided in the inner cavity of the inner cylinder 1. The partition 14 divides the inner cavity of the inner cylinder 1 into a clothing processing chamber 71 and a drainage chamber 72. A drainage hole 141 is provided on the partition 14 to connect the clothing processing chamber 71 and the drainage chamber 72. The water guiding structure 2 is located in the drainage chamber 72.

[0112] The inner cavity of the inner drum 1 is divided into a clothes handling cavity 71 for holding laundry and a drain cavity 72 by the partition 14. The water guiding structure 2 is located in the drain cavity 72. In other words, the partition 14 separates the water guiding structure 2 from the laundry. This design can effectively prevent the laundry from getting tangled on the water guiding structure 2, and to a certain extent, it effectively protects both the clothes and the water guiding structure 2, ensuring good safety and improving user satisfaction.

[0113] In a specific implementation, the inner cylinder 1 includes a cylinder body 11, a rear cover 12 located at the rear end of the cylinder body 11, and a front cover 13 located at the front end of the cylinder body 11. The rear cover 12 and the front cover 13 can be welded to the inner cylinder 1, resulting in good overall integrity and high structural strength. Alternatively, the rear cover 12 and the front cover 13 can be connected to the inner cylinder 1 using bolts or other fasteners. The partition 14 can be welded into the inner cylinder 1, for example, resulting in good overall integrity and high structural strength.

[0114] Furthermore, the partition 14 can be positioned close to the rear cover 12, that is, the partition 14 is positioned in the inner cavity of the drum 11 on the side close to the rear cover 12. With this design, the volume of the clothes handling chamber 71 is increased as much as possible without changing the overall outer contour size of the inner drum structure, thereby increasing the washing capacity of the inner drum 1 and helping to develop the clothes handling device towards a larger capacity.

[0115] In a specific implementation, multiple drainage holes 141 can be provided on the partition 14, and the multiple drainage holes 141 are arranged at intervals along the circumference of the partition 14 to form a set of drainage holes 141.

[0116] Multiple drainage holes 141 are provided at intervals along the circumference of the partition 14. In other words, multiple drainage channels are provided between the clothes processing chamber 71 and the drainage chamber 72, thereby saving drainage time, improving drainage efficiency, shortening washing time, and improving user satisfaction.

[0117] Alternatively, some of the drainage holes 141 may be spaced circumferentially along the partition 14, while others may be spaced radially along the partition 14, further improving drainage efficiency.

[0118] In some embodiments, reference Figure 1 As shown, the drain hole 141 is located near the radial edge of the partition 14. During drainage, the water is thrown towards the radial outer edge of the inner cylinder 1 under the action of centrifugal force and rotates with the inner cylinder 1. By placing the drain hole 141 near the radial outer edge of the partition 14, the drainage path is shortened, allowing the water to quickly enter the drainage chamber 72 and the drainage channel from the drain hole 141 under the action of centrifugal force and be discharged, further improving the drainage efficiency.

[0119] In practice, multiple notches can be provided at intervals along the circumference of the partition 14 at the radial edge of the partition 14. When the partition 14 surrounds the inner cavity of the inner cylinder 1, each notch and the corresponding side wall of the inner cylinder 1 respectively enclose and define a drain hole 141. In this way, under the action of centrifugal force, when the water is thrown onto the side wall of the inner cavity of the inner cylinder 1, it can flow into the water guiding channel along the inner cavity of the inner cylinder 1, resulting in higher drainage efficiency.

[0120] Because stainless steel is not prone to accumulating dirt and bacteria, and has good antibacterial properties, in practice, the partition 14, the back cover 12, and the inner drum 1 can be made of stainless steel. For example, the wall of the drain chamber 72 that houses the water guiding structure 2 is entirely made of stainless steel. This makes it less prone to accumulating dirt and bacteria, and has good antibacterial properties. To a certain extent, this avoids cross-contamination between the drain chamber 72 and the clothes processing chamber 71, further improving the cleanliness and health performance of the washing process, and providing a good user experience.

[0121] Example 2

[0122] This embodiment also provides a clothing processing device, such as a drum washing machine, a clothes dryer, etc.

[0123] The garment processing device includes an outer shell and an inner cylinder structure located inside the outer shell.

[0124] The inner cylinder structure in this embodiment has the same specific structure and implementation principle as the inner cylinder structure provided in the above embodiments, and can bring the same or similar technical effects. It will not be described in detail here. For details, please refer to the description of the above embodiments.

[0125] The clothing processing device provided in this embodiment includes an inner cylinder 1, a water guiding structure 2, and a main shaft assembly 4 for driving the inner cylinder 1 to rotate, all housed within the outer casing. The water guiding structure 2 is located in the inner cavity of the inner cylinder 1 and has a water guiding channel communicating with the inner cavity of the inner cylinder 1. The outlet 213 of the water guiding channel is connected to a water outlet shaft 3. That is, the inlet 212 of the water guiding channel is connected to the inner cavity of the inner cylinder 1, and the outlet 213 of the water guiding channel is connected to the water outlet shaft 3. The water outlet shaft 3 extends through the rear cover 12 of the inner drum 1 and is inserted into the hollow rotating shaft 42 of the main shaft assembly 4 that drives the inner drum 1 to rotate. The water outlet shaft 3 does not rotate. Therefore, during drainage or spin-drying, as the inner drum 1 rotates, the water in the inner cavity of the inner drum 1 is discharged to the outside of the clothing processing device through the water guiding channel of the water guiding structure 2 and the water outlet shaft 3 under the action of centrifugal force. In other words, the inner drum structure provided in this embodiment of the invention directly discharges water to the outside of the clothing processing device through the guidance of the water guiding structure 2, without requiring external driving force, thus saving energy. Furthermore, by inserting the water outlet shaft 3 into the hollow rotating shaft, the structure of the main shaft assembly is effectively utilized, saving space to a certain extent.

[0126] It should be noted that the clothing processing device provided in this embodiment does not have an outer drum. A water guiding structure 2 is provided within the inner cavity of the inner drum 1. The water guiding structure 2 has a water guiding channel communicating with the inner drum of the inner drum 1. A water outlet shaft 3 is connected to the outlet 213 of the water guiding channel, and the water outlet shaft passes through the hollow rotating shaft 42 of the main shaft assembly used to drive the rotation of the inner drum 1. Water is directly guided and discharged to the outside of the clothing processing device through the water guiding structure 2 and the water outlet shaft 3, eliminating the need for external driving force and saving energy and cost. Simultaneously, since there is no need for an outer drum, washing water is saved, and the space occupied by the clothing processing device with this inner drum structure is reduced to a certain extent, enabling the clothing processing device to develop towards a smaller size and occupy less space.

[0127] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
