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 clothing processing device. The inner cylinder structure includes an inner cylinder and a water guiding structure. The inner cylinder has a drain hole, and the outer side of the inner cylinder has a water collecting cavity communicating with the drain hole. The water guiding structure is located inside the water collecting cavity and has a water guiding channel communicating with the water collecting cavity, so that water in the inner cavity of the inner cylinder is discharged to the outside of the clothing processing device in sequence through the drain hole, the water collecting cavity, and the water guiding channel.

[0005] The inner drum structure of the garment processing device provided in this embodiment of the invention features a drain hole on the inner drum, creating a water collection chamber on the outer side of the inner drum that communicates with the drain hole. Specifically, the inner cavity of the inner drum is connected to the water collection chamber via the drain hole. Simultaneously, a water guiding structure is installed within the water collection chamber, and this structure has a water guiding channel that communicates with the water collection chamber. Therefore, the water guiding channel communicates with the inner cavity of the inner drum via the drain hole and the water collection chamber. During drainage or spin-drying, as the inner drum rotates, the water in the inner cavity is sequentially discharged to the outside of the garment processing device through the drain hole, the water collection chamber, and the water guiding channel under 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 providing a water collection chamber on the outer side of the inner drum, the water collection chamber has a certain water-gathering effect. Since the water guiding structure is located within the water collection chamber, the entire drainage process is smoother, further improving drainage efficiency and thus further saving energy.

[0006] Optionally, a water collecting ring is fitted on the outer side of the inner cylinder, and the water collecting ring and the outer wall of the inner cylinder together define the water collecting cavity.

[0007] This design is simple and easy to assemble.

[0008] Optionally, the inner cylinder includes a cylinder body and a rear cover disposed at the rear end of the cylinder body; the water collecting ring is sleeved on the outer side of the rear end of the cylinder body, the rear cover is located inside the water collecting ring, and the outer wall of the cylinder body, the rear cover and the water collecting ring together define the water collecting cavity;

[0009] The drain hole is located on the rear cover, and / or the drain hole is located in the area of ​​the cylinder covered by the water collection ring.

[0010] In this way, when draining, the water in the inner cavity of the drum can be discharged from the rear end of the drum under the action of centrifugal force, without the need to put an outer drum on the outside of the inner drum. This achieves single-drum washing and drainage of the inner drum, which reduces cross-contamination to a certain extent and improves the cleanliness and health of washing.

[0011] Optionally, the water guiding structure is located between the rear cover and the water collection ring.

[0012] This design saves space between the radial outer edge of the water collection ring and the radial outer edge of the inner cylinder, effectively utilizing the internal space of the inner cylinder structure and facilitating the miniaturization of clothing processing devices.

[0013] Optionally, there are multiple drainage holes, which are spaced apart circumferentially along the inner cylinder.

[0014] Multiple drain holes are provided along the circumference of the inner drum, which saves drainage time, improves drainage efficiency, and thus shortens washing time and increases user satisfaction.

[0015] Optionally, the inner cylinder includes a cylinder body and a rear cover disposed at the rear end of the cylinder body. A water collection ring is connected to the rear cover, and the rear cover and the water collection ring together define a water collection cavity. A drain hole is opened in the area of ​​the rear cover covered by the water collection ring.

[0016] In this way, when draining, as the drum rotates, the water in the inner cavity of the drum can be discharged from the back cover of the drum under the action of centrifugal force, realizing single-drum washing and drainage, which improves the cleanliness and health of washing.

[0017] Optionally, one end of the water collecting ring has a flange bent toward the outer wall of the inner cylinder, and the flange is sealed to the outer wall of the inner cylinder.

[0018] This design makes it easier to connect the water collection ring to the inner cylinder, while also improving the sealing performance at the joint between the water collection ring and the inner cylinder, resulting in high reliability.

[0019] Optionally, the inner cylinder structure further includes a main shaft assembly for driving the inner cylinder to rotate and a support frame for supporting the main shaft assembly; the support frame is located on the side of the water collecting ring away from the inner cylinder, the water collecting ring is provided with a clearance hole for the water guiding structure to pass through, and the water guiding structure is connected to the support frame.

[0020] By fixing the water guiding structure to the support frame, on the one hand, there is no need to set up a special support structure to fix the water guiding structure, saving costs and layout space; on the other hand, it will not interfere with the rotation of the inner cylinder and the water collection ring, ensuring good safety in use.

[0021] Optionally, the water guiding structure includes a water guiding part and a connecting part. The water guiding part has the water guiding channel, the connecting part is connected to the water guiding part, and the water guiding structure is connected to the support frame through the connecting part.

[0022] The water guiding part is stably fixed to the support frame by the connecting part, so that when the inner cylinder and the water collecting ring rotate to drain water, the water guiding structure remains stationary. That is, the water guiding structure will not be displaced during drainage, so that water can quickly enter the water guiding channel and be discharged under the action of centrifugal force, shortening the drainage path and improving drainage efficiency.

[0023] Optionally, the water guiding portion includes a hollow first water guiding extension and a hollow second water guiding extension, the inner cavity of the first water guiding extension and the inner cavity of the second water guiding extension are connected to form the water guiding channel; the inlet of the water guiding channel is located on the first water guiding extension, the outlet of the water guiding channel is located on the second water guiding extension, and the second water guiding extension extends through the clearance hole; the connecting portion is disposed on the second water guiding extension and is located outside the water collecting ring.

[0024] This design allows the water guiding structure to be rationally configured according to the internal space of the inner cylinder structure, saving space; by placing the connecting part outside the water collecting ring, it is easier to connect the connecting part to the support frame, improving the ease of assembly.

[0025] Optionally, in the direction from the rotation axis of the main shaft assembly to the radial outer edge of the water collection cavity, the first water guiding extension extends toward the radial outer edge of the water collection cavity; the inlet of the water guiding channel is located at one end of the first water guiding extension near the radial outer edge.

[0026] During drainage or dehydration, the water is thrown towards the radial outer edge of the water collection chamber under the action of centrifugal force and rotates with the water collection chamber. The first water guiding extension section extends towards the radial outer edge of the water collection chamber, and the entrance of the water guiding channel is opened at one end of the first water guiding extension section near the radial outer edge of the water collection chamber. This shortens the drainage path and allows the rotating water to quickly enter the water guiding channel and be discharged under the action of centrifugal force, further improving drainage efficiency.

[0027] Optionally, the connecting part includes a connecting plate, which is an arc-shaped structure that matches the shape of the part of the support frame that mates with the connecting part.

[0028] This design allows the connecting plate and the support frame to work together better, making installation easier and improving the support effect of the support frame on the water guiding structure to a certain extent.

[0029] Optionally, the connecting plate is provided with reinforcing ribs.

[0030] This design improves the structural strength of the connecting plate, thus providing a more stable and reliable support for the water-conducting structure.

[0031] Optionally, the water collecting ring is a stainless steel water collecting ring; and / or, the inner cylinder is a stainless steel inner cylinder.

[0032] With this design, the water collection ring and / or inner drum are made of stainless steel. Since stainless steel is not prone to accumulating dirt and bacteria, and has good antibacterial properties, it further improves the cleanliness and health performance of the wash, resulting in a better user experience.

[0033] Optionally, the inlet of the water guiding channel is located near the radial outer edge of the water collecting cavity.

[0034] During drainage, the water is thrown towards the radial outer edge of the water collection chamber 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 water collection chamber, the drainage path is shortened. Under the action of centrifugal force, the rotating water can quickly enter the water guide channel from the inlet, which further improves the drainage efficiency.

[0035] Optionally, the inlet of the water guiding channel is oriented toward the rotation direction of the water collecting chamber.

[0036] During drainage or dehydration, the water is thrown towards the radial outer edge of the water collection chamber under the action of centrifugal force and rotates with the water collection chamber. The inlet of the water guide channel faces the rotation direction of the water collection chamber. In other words, the inlet of the water guide channel is opposite to the rotation direction of the water in the water collection chamber, which further shortens the drainage path and improves drainage efficiency.

[0037] Optionally, the inlet of the water guiding channel is located above the rotation axis of the inner cylinder; 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.

[0038] 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.

[0039] Optionally, there are at least two water guiding structures, and at least two water guiding structures are arranged at intervals along the circumference of the water collecting cavity within the water collecting cavity.

[0040] The design incorporates multiple water-guiding structures, which further reduces drainage time and improves drainage efficiency, thereby shortening washing time and contributing to increased user satisfaction.

[0041] Optionally, at least one of the water guiding structures is located in a different position in the axial direction of the water collecting cavity than the other water guiding structures are located in the axial direction of the water collecting cavity.

[0042] With this configuration, when multiple water guiding structures are installed in the water collection cavity, at least one water guiding structure is located at a different position than the others along the axial direction of the water collection cavity. That is, the water guiding structures are staggered along the axial direction of the water collection cavity, which further improves drainage efficiency and enhances the user experience.

[0043] 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

[0053] 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.

[0054] 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.

[0055] 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.

[0056] The inner cylinder has multiple drainage holes on its radial outer edge that connect the inner and outer cylinders.

[0057] 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.

[0058] The inner cylinder structure and the garment processing device of this invention will be explained and described in detail below through specific embodiments:

[0059] Example 1

[0060] refer to Figures 1 to 6 As shown in the figure, this embodiment provides an inner drum structure (hereinafter referred to as inner drum structure) for a clothing processing device, wherein the clothing processing device may be, for example, a drum washing machine, a clothes dryer, etc.

[0061] The inner cylinder structure includes an inner cylinder 1 and a water guiding structure 2. The inner cylinder 1 has a drain hole 13. The outer side of the inner cylinder 1 has a water collecting cavity 31 that communicates with the drain hole 13. The water guiding structure 2 is located inside the water collecting cavity 31 and has a water guiding channel that communicates with the water collecting cavity 31, 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 drain hole 13, the water collecting cavity 31, and the water guiding channel.

[0062] It is understandable that the inner cavity of the inner cylinder 1 is connected to the water collection cavity 31 through the drain hole 13. Since the water collection cavity 31 is provided with a water guiding structure 2, and the water guiding channel of the water guiding structure 2 is also connected to the water collection cavity 31, the inner cavity of the inner cylinder 1 is connected to the water guiding structure 2 through the drain hole 13 and the water collection cavity 31. That is, the inner cavity of the inner cylinder 1 is connected to the water guiding channel of the water guiding structure 2, which facilitates drainage.

[0063] During drainage or spin-drying, the inner drum 1 rotates at medium to high speed, while the water guiding structure 2 remains stationary. That is, the inner drum 1 can rotate relative to the water guiding structure 2. Water in the inner cavity of the inner drum 1, under centrifugal force, first enters the water collection chamber 31 through the drain hole 13, and is then thrown towards the radial outer edge of the water collection chamber 31, rotating at high speed before entering the water guiding channel and being discharged to the outside of the garment processing device. In other words, the inner drum structure provided in this embodiment, by setting a water collection chamber 31 on the outside of the inner drum 1 and setting a water guiding structure 2 communicating with the inner cavity of the inner drum 1 within the water collection chamber 31, eliminates the need for external driving force. During spin-drying or drainage, water in the inner drum 1 is discharged sequentially through the drain hole 13, the water collection chamber 31, and the water guiding channel under centrifugal force, saving energy. Simultaneously, since no external driving force is required, costs are reduced to a certain extent.

[0064] It should be noted that the water collecting cavity 31 and the inner cylinder 1 are coaxially arranged. The circumferential direction of the water collecting cavity 31 is consistent with the circumferential direction of the inner cylinder 1, the axial direction of the water collecting cavity 31 is consistent with the axial direction of the inner cylinder 1, and the radial direction of the water collecting cavity 31 is consistent with the radial direction of the inner cylinder 1.

[0065] It should be noted that the clothing processing device provided in this embodiment does not have an outer cylinder. By setting a water collection cavity 31 on the outside of the inner cylinder 1 and setting a water guiding structure 2 in the water collection cavity 31 that communicates with the inner cavity of the inner cylinder 1, water is directly discharged to the outside of the clothing processing device through the guidance of the water guiding structure 2. No external driving force is required, which saves energy and cost.

[0066] The inner tube structure provided in this embodiment has a drain hole 13 on the inner tube 1, so that the outer side of the inner tube 1 has a water collection cavity 31 that communicates with the drain hole 13. That is, the inner cavity of the inner tube 1 is connected to the water collection cavity 31 through the drain hole 13. At the same time, the water collection cavity 31 is provided with a water guiding structure 2, which has a water guiding channel that communicates with the water collection cavity 31. Therefore, the water guiding channel is connected to the inner cavity of the inner tube 1 through the drain hole 13 and the water collection cavity 31. In this way, when draining or dehydrating, as the inner tube 1 rotates, the water in the inner cavity of the inner tube 1 is discharged to the outside of the clothing processing device in sequence through the drain hole 13, the water collection cavity 31, and the water guiding channel under the action of centrifugal force. In other words, the inner tube 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 the need for external driving force, thus saving energy consumption. In addition, by setting a water collection cavity 31 on the outside of the inner cylinder 1, the water collection cavity 31 has a certain water collection effect. Since the water guiding structure 2 is located inside the water collection cavity 31, the entire drainage is smoother, further improving the drainage efficiency and thus further saving energy.

[0067] In some embodiments, reference Figure 1 and Figure 3 As shown, a water collecting ring 3 is sleeved on the outer side of the inner cylinder 1. The water collecting ring 3 and the outer wall of the inner cylinder 1 together define a water collecting cavity 31. The structure is simple, easy to manufacture, and easy to assemble.

[0068] It should be noted that the water collecting ring 3 is sleeved on the outside of the inner cylinder 1, and the water collecting ring 3 is coaxially arranged with the inner cylinder 1.

[0069] In a specific implementation, the water collecting ring 3 is sleeved on the outer side of at least a portion of the inner cylinder 1, and the inner wall of the water collecting ring 3 and the outer wall of the inner cylinder 1 together define the water collecting cavity 31. The water guiding structure 2 is located inside the water collecting cavity 31, and the water guiding channel of the water guiding structure 2 is connected to the inner cavity of the inner cylinder 1 through the drain hole 13.

[0070] The water collecting ring 3 can be welded to the inner cylinder 1, resulting in good integrity and high structural strength. Alternatively, the water collecting ring 3 can also be connected to the inner cylinder 1 using bolts or other fasteners.

[0071] Further, refer to Figure 1 As shown, the inner cylinder 1 includes a cylinder body 11 and a rear cover 12 disposed at the rear end of the cylinder body 11.

[0072] 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.

[0073] The rear cover 12 can be welded to the inner cylinder 1, resulting in good integrity and high structural strength. Alternatively, the rear cover 12 can also be connected to the inner cylinder 1 using bolts or other fasteners.

[0074] refer to Figure 1 and Figure 3 As shown, the rear cover 12 is located at the rear end of the cylinder 11, the water collecting ring 3 is sleeved on the outer side of the rear end of the cylinder 11, the rear cover 12 is located inside the water collecting ring 3, the outer wall of the cylinder 11, the rear cover 12 and the water collecting ring 3 together define the water collecting cavity 31, and the rear cover 12 and the inner wall of the cylinder 11 together define the washing cavity 7 for holding washing water and washing clothes.

[0075] In practice, the drain hole 13 can be opened only on the rear cover 12, or it can be opened only in the area of ​​the cylinder 11 covered by the water collection ring 3. Of course, the drain hole 13 can also be opened in both the rear cover 12 and the area of ​​the cylinder 11 covered by the water collection ring 3. It can be selected arbitrarily according to the specific usage environment, as long as the inner cavity of the cylinder 11, i.e., the washing cavity 7, can be connected to the water collection cavity 31 through the drain hole 13. No further restrictions are imposed here.

[0076] A water collection ring 3 is fitted onto the outer side of the rear end of the drum 11, and a rear cover 12 is located inside the water collection ring 3, which together with the outer wall of the drum 11 and the water collection ring 3 defines the water collection cavity 31. At the same time, a drain hole 13 connecting the water collection cavity 31 and the inner cavity of the drum 11 is opened in the area covered by the rear cover 12 and / or the drum 11 by the water collection ring 3. In this way, when draining, the water in the inner cavity of the drum 11 can be discharged from the rear end of the drum 11 under the action of centrifugal force, without the need to fit an outer drum on the outside of the inner drum 1. This achieves single-drum washing and drainage of the inner drum 1, which reduces cross-contamination to a certain extent and improves the cleanliness and health of washing.

[0077] For specific implementation, refer to Figures 1 to 3 As shown, the inner cylinder 1 also includes a front cover 14, which is disposed at the front end of the cylinder body 11.

[0078] In some embodiments, reference Figure 3 As shown, the water guiding structure 2 is located between the back cover 12 and the water collecting ring 3. This design saves the size between the radial outer edge of the water collecting ring 3 and the radial outer edge of the inner cylinder 1, effectively utilizing the internal space of the inner cylinder structure. This further facilitates the miniaturization of the clothing processing device and results in a reasonable layout.

[0079] Furthermore, the drain hole 13 is opened on the rear cover 12. In this way, when dehydrating or draining, the water in the inner cavity of the inner cylinder 1 can quickly enter the water guiding structure 2 and be discharged after passing through the drain hole 13 on the rear cover 12 under the action of centrifugal force. Compared with opening the drain hole 13 in the area covered by the water collecting ring 3 of the cylinder 11, the drainage path between the inner cavity of the inner cylinder 1 and the water guiding channel of the water guiding structure 2 is shortened, the drainage time is saved, and the drainage efficiency is further improved.

[0080] For specific implementation, refer to Figure 1 and Figure 2 As shown, there can be multiple drain holes 13, which are spaced apart along the circumference of the inner cylinder 1 in the area covered by the water collection ring 3 of the rear cover 12 and / or the cylinder 11.

[0081] Multiple drain holes 13 are provided along the circumference of the inner drum 1, thereby saving drainage time, improving drainage efficiency, shortening washing time, and enhancing user satisfaction.

[0082] For example, if the rear cover 12 has multiple drainage holes 13, some of the drainage holes 13 can also be arranged at intervals along the radial direction of the rear cover 12. That is, some drainage holes 13 are arranged at intervals along the circumference of the rear cover 12 to form a group of drainage holes 13, and multiple groups of drainage holes 13 can be arranged at intervals along the axial direction of the rear cover 12, which further improves the drainage efficiency.

[0083] In other embodiments, the inner cylinder 1 includes a cylinder body 11 and a rear cover 12 disposed at the rear end of the cylinder body 11. A water collecting ring 3 is connected to the rear cover 12. The rear cover 12 and the water collecting ring 3 together define a water collecting cavity 31. A drain hole 13 is opened in the area of ​​the rear cover 12 covered by the water collecting ring 3.

[0084] In this way, during drainage, as the drum 11 rotates, the water in the inner cavity of the drum 11 can be discharged from the rear cover 12 of the drum 11 under the action of centrifugal force, realizing single-drum washing and drainage of the inner drum 1, and improving the cleanliness and health of washing.

[0085] In some embodiments, reference Figure 3 As shown, one end of the water collecting ring 3 has a flange 32 that bends toward the outer wall of the inner cylinder 1, and the flange 32 is sealed to the outer wall of the inner cylinder 1.

[0086] This design makes it easier to connect the water collecting ring and the inner cylinder, while also improving the sealing performance at the joint between the water collecting ring 3 and the inner cylinder 1, resulting in high reliability.

[0087] Among them, the shape of the side of the flange 32 near the outer wall of the inner cylinder 1 matches the shape of the outer wall of the inner cylinder 1, so that the fit and sealing are good when connected.

[0088] refer to Figure 1 and Figure 3 As shown, the inner cylinder structure also includes a main shaft assembly 4 for driving the inner cylinder 1 to rotate and a support frame 5 for supporting the main shaft assembly 4. The support frame 5 is located on the side of the water collecting ring 3 away from the inner cylinder 1, that is, the support frame 5 is located on the rear side of the water collecting ring 3. The water collecting ring 3 is provided with a clearance hole for the water guiding structure 2 to pass through, and the water guiding structure 2 is connected to the support frame 5.

[0089] A support frame 5 is set outside the water collection ring 3 to support the main shaft assembly 4. The water guiding structure 2 is fixed on the support frame 5. On the one hand, there is no need to set up a special support structure to fix the water guiding structure 2, which saves costs and layout space. On the other hand, it will not interfere with the rotation of the inner cylinder 1 and the water collection ring 3, and has good safety in use.

[0090] In specific implementation, the main shaft assembly 4 is located inside the water collection cavity 31. The main shaft assembly 4 includes a support base 41 and a rotating shaft 42. The rotating shaft 42 is coaxially arranged at the center of the support base 41 and is fixed relative to the support base 41. The rotating shaft 42 extends toward the water collection ring 3 and passes through to the outside of the water collection ring 3. The inner cylinder 1 is coaxially arranged on the side of the support base 41 away from the water collection ring 3. The water guiding structure 2 is located between the support base 41 and the water collection ring 3, that is, the water guiding structure 2 is located on the outside of the support base 41 and has a gap with the rotating shaft 42.

[0091] 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 drum body 11 to rotate.

[0092] The water guiding structure 2 is inserted into the clearance hole and fixed relative to the support frame 5. The inner cylinder 1 is coaxially mounted on the main shaft assembly 4 and can rotate with the rotation of the main shaft assembly 4. The rotating shaft 42 of the main shaft assembly 4 is rotatably connected to the support frame 5. It can be understood that the main shaft assembly 4 drives the inner cylinder 1 to rotate relative to the support frame 5, that is, the inner cylinder 1 can rotate relative to the water guiding structure 2. Thus, the water in the inner cavity of the inner cylinder 1 can be discharged sequentially through the drain hole 13, the water collection cavity 31, and the water guiding structure 2 under the action of centrifugal force.

[0093] refer to Figure 3 As shown, there is a safe distance between the opening on the water collecting ring 3 through which the rotating shaft 42 passes and the clearance hole on the water collecting ring 3 through which the water guiding structure 2 passes, so that the water guiding structure 2 will not interfere with the rotation of the inner cylinder 1 and the rotating shaft 42 assembly, thus ensuring good safety.

[0094] For specific implementation, refer to Figure 1As shown, the support base 41 is provided with at least two first mounting holes 43, which are spaced apart along the circumference of the support base 41; the cylinder 11 is provided with at least two second mounting holes (not shown), which are spaced apart along the circumference of the cylinder 11, with one first mounting hole 43 corresponding to one second mounting hole. The spindle assembly 4 is detachably connected to the cylinder 11 by fasteners passing through the first mounting holes 43 and the corresponding second mounting holes. If the cylinder 11 and the spindle assembly 4 are damaged and need to be replaced or repaired, they can be separated and the damaged parts can be disassembled for replacement or repair, which saves costs to a certain extent.

[0095] In other embodiments, the support base 41 may also be welded to the cylinder 11.

[0096] In some embodiments, reference Figure 1 , Figures 4 to 6 As shown, the water guiding structure 2 includes a water guiding part 21 and a connecting part 22. The water guiding part 21 has a water guiding channel, and the connecting part 22 is connected to the water guiding part 21. The water guiding structure 2 is connected to the support frame 5 through the connecting part 22. The structure is simple and easy to assemble.

[0097] The water guiding part 21 is stably fixed to the support frame 5 by the connecting part 22, so that when the inner cylinder 1 and the water collecting ring 3 rotate to drain water, the water guiding structure 2 remains stationary. That is, the water guiding structure 2 will not be displaced during drainage, so that water can quickly enter the water guiding channel and be discharged under the action of centrifugal force, shortening the drainage path and improving drainage efficiency.

[0098] In some embodiments, reference Figure 4 and Figure 5 As shown, the water guiding section 21 includes a hollow first water guiding extension section 211 and a hollow second water guiding extension section 212. The inner cavity of the first water guiding extension section 211 is connected to the inner cavity of the second water guiding extension section 212 to form a water guiding channel together. The structure is simple and easy to manufacture.

[0099] There is an angle between the first water-guiding extension section 211 and the second water-guiding extension section 212. For example, the first water-guiding extension section 211 and the second water-guiding extension section 212 are formed into an L-shaped water-guiding structure 2, which facilitates the water-guiding structure 2 to pass through the water-collecting ring 3 and extend to the outside of the water-collecting ring 3 and be fixedly connected to the support frame 5.

[0100] Of course, in other embodiments, the support frame 5 may also be inserted through the water collection ring 3 and extend into the water collection cavity 31 to connect with the connecting part 22.

[0101] Among them, reference Figure 3As shown, the first water-guiding extension 211 is located inside the water collection cavity 31, and the inlet 213 of the water-guiding channel is located on the first water-guiding extension 211. It can be understood that the inlet 213 of the water-guiding channel is located inside the water collection cavity 31. At least a portion of the second water-guiding extension 212 is located inside the water collection cavity 31, and the outlet 214 of the water-guiding channel is located on the second water-guiding extension 212. The second water-guiding extension 212 extends through a clearance hole to connect with the support frame 5. The outlet 214 of the water-guiding channel can be located inside the water collection cavity 31. In this case, the drain pipe communicating with the outside extends into the water collection cavity 31 and communicates with the outlet 214 of the water-guiding channel. Of course, the outlet 214 of the water-guiding channel can also be located outside the water collection cavity 31 for ease of assembly.

[0102] In addition, the connecting part 22 is provided on the second water guiding extension section 212, and the connecting part 22 is located outside the water collecting ring 3 for easy assembly.

[0103] refer to Figure 3 As shown, when both the connecting part 22 and the outlet 214 of the water guiding channel are located on the portion of the second water guiding extension 212 outside the water collecting ring 3, the outlet 214 of the water guiding channel and the connecting part 22 are arranged opposite to each other, which is a reasonable layout and avoids interference.

[0104] This arrangement allows the water guiding channel to be rationally configured according to the internal space of the inner cylinder structure, saving space. By placing the connecting part 22 outside the water collecting ring 3, that is, by placing the connecting part 22 outside the water collecting ring 3, it is easier to connect the connecting part 22 to the support frame 5, improving the ease of assembly. In some embodiments, refer to Figure 3 As shown, in the direction along the rotation axis of the main shaft assembly 4 to the radial outer edge of the water collection cavity 31, the first water guiding extension 211 extends toward the radial outer edge of the water collection cavity 31. The inlet 213 of the water guiding channel is located at one end of the first water guiding extension 211 near the radial outer edge, which helps to reduce the distance between the inlet 213 of the water guiding channel and the radial outer edge of the water collection cavity 31, further shortening the drainage path. Thus, when water is thrown against the inner wall of the water collection cavity 31 under the action of centrifugal force and rotates with the water collection cavity 31, the first water guiding extension 211 can form a more powerful interception of water, thereby allowing water to quickly enter the water guiding channel and be discharged, resulting in high drainage efficiency.

[0105] During drainage or dehydration, the water is thrown towards the radial outer edge of the water collection chamber 31 under the action of centrifugal force and rotates with the water collection chamber 31. This causes the first water guiding extension section 211 to extend towards the radial outer edge of the water collection chamber 31, and the inlet 213 of the water guiding channel is opened at one end of the first water guiding extension section 211 near the radial outer edge of the water collection chamber 31. This shortens the drainage path and allows the rotating water to quickly enter the water guiding channel and be discharged under the action of centrifugal force, further improving drainage efficiency.

[0106] In some embodiments, reference Figure 4 and Figure 5 As shown, the connecting part 22 includes a connecting plate, which is an arc-shaped structure that matches the shape of the part of the support frame 5 that mates with the connecting part 22.

[0107] This design allows the connecting plate and support frame 5 to work together better, making installation easier and improving the support effect of the support frame 5 on the water guiding structure 2 to a certain extent.

[0108] The connecting plate and the second water-guiding extension section 212 can be integrally formed, resulting in good integrity and high structural strength. Of course, the connecting plate and the second water-guiding extension section 212 can also be connected together by welding or bolts.

[0109] In some embodiments, reference Figure 4 and Figure 5 As shown, the connecting plate is provided with reinforcing ribs 6. This design improves the structural strength of the connecting plate, thereby providing more stable and reliable support for the water guiding structure 2.

[0110] In practice, the reinforcing rib 6 is set on the side of the connecting plate facing the second water-guiding extension section 212.

[0111] In some embodiments, the water collecting ring 3 is a stainless steel water collecting ring; and / or, the inner cylinder 1 is a stainless steel inner cylinder.

[0112] In practice, only the water collecting ring 3 can be made of stainless steel, or only the inner cylinder 1 can be made of stainless steel. Of course, both the water collecting ring 3 and the inner cylinder 1 can be made of stainless steel. The choice can be made arbitrarily according to the specific usage environment, and no further restrictions are imposed here.

[0113] Because stainless steel is not prone to accumulating dirt and bacteria, and has good antibacterial properties, the water collection ring 3 and / or the inner drum 1 are made of stainless steel. In particular, the water collection ring 3 is made of stainless steel, which can further improve the cleanliness and health performance of washing, resulting in a better user experience.

[0114] For specific implementation, refer to Figure 1 As shown, the inlet 213 of the water guiding channel is located near the radial outer edge of the water collecting cavity 31.

[0115] The inlet 213 of the water guiding channel is located close to the radial outer edge of the water collecting cavity 31. That is, the distance between the inlet 213 of the water guiding channel and the radial outer edge of the water collecting cavity 31 is less than the distance between the inlet 213 of the water guiding channel and the rotation axis of the water collecting cavity 31.

[0116] During drainage, the water is thrown towards the radial outer edge of the water collection chamber 31 under the action of centrifugal force and rotates with the water collection chamber 31. By setting the inlet 213 of the water guide channel close to the radial outer edge of the water collection chamber 31, the drainage path is shortened. Under the action of centrifugal force, the rotating water can quickly enter the water guide channel from the inlet 213, saving drainage time and further improving drainage efficiency.

[0117] Furthermore, the inlet 213 of the water guiding channel is oriented in the direction of rotation of the water collecting chamber 31.

[0118] During drainage or dehydration, the water is thrown towards the radial outer edge of the water collection chamber 31 under the action of centrifugal force and rotates with the water collection chamber 31. The inlet 213 of the water guide channel faces the rotation direction of the water collection chamber 31. That is to say, the inlet 213 of the water guide channel is opposite to the rotation direction of the water in the water collection chamber 31, which further shortens the drainage path and improves the drainage efficiency.

[0119] Of course, the water guiding structure 2 can be provided with multiple inlets 213 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 213 can face the rotation direction of the water collecting cavity 31, or they can be partially facing the rotation direction of the water collecting cavity 31.

[0120] In some embodiments, the inlet 213 of the water guide channel is located above the rotation axis of the inner cylinder 1; the height of the inlet 213 of the water guide channel is higher than the height of the outlet 214 of the water guide channel, and the height of the water guide channel decreases sequentially along the direction from the inlet 213 to the outlet 214 of the water guide channel. With this design, the water in the inner cylinder can be smoothly discharged after entering the water guide channel under the action of centrifugal force, which further improves the drainage efficiency.

[0121] In some embodiments, there are multiple water guiding structures 2, and the multiple water guiding structures 2 are arranged at intervals along the circumference of the water collecting cavity 31 within the water collecting cavity 31.

[0122] Multiple water guiding structures 2 are set in the water collection cavity 31, that is, multiple water guiding channels are constructed between the inner cylinder 1 and the outside, which further saves drainage time, improves drainage efficiency, and thus shortens washing time, which helps to improve user satisfaction.

[0123] Of course, when multiple water guiding structures 2 are arranged in the water collection cavity 31, at least one of the water guiding structures 2 is located in a different position in the axial direction of the water collection cavity 31 than the other water guiding structures 2. That is, at least one water guiding channel inlet 213 is located in a different position in the axial direction of the water collection cavity 31 than the other water guiding channel inlet 213. In other words, the water guiding structures 2, i.e. the water guiding channel inlet 213, are staggered along the axial direction of the water collection cavity 31, which further improves drainage efficiency and enhances the user experience.

[0124] With this configuration, during drainage or dehydration, the water in the inner cavity of the inner cylinder 1 can not only be discharged from multiple water guide channels under the action of centrifugal force, but also enter the water guide channels from different positions in the axial direction of the water collection cavity 31 and be discharged, further improving drainage efficiency and enhancing the user experience.

[0125] Example 2

[0126] This embodiment also provides a clothing processing device, such as a drum washing machine, a clothes dryer, etc.

[0127] The garment processing device includes an outer shell and an inner cylinder structure located inside the outer shell.

[0128] 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.

[0129] The garment processing device provided in this embodiment includes an inner cylinder 1 and a water guiding structure 2 within the outer casing. The inner cylinder 1 has a drain hole 13, and its outer side has a water collecting cavity 31 communicating with the drain hole 13. In other words, the inner cavity of the inner cylinder 1 is connected to the water collecting cavity 31 through the drain hole 13. The water guiding structure 2 is located within the water collecting cavity 31 and has a water guiding channel communicating with the water collecting cavity 31. Therefore, the water guiding channel communicates with the inner cavity of the inner cylinder 1 through the drain hole 13 and the water collecting cavity 31. Thus, during drainage or dehydration, as the inner cylinder 1 rotates, the water in the inner cavity of the inner cylinder 1 is discharged sequentially through the drain hole 13, the water collecting cavity 31, and the water guiding channel to the outside of the garment processing device under the action of centrifugal force. In other words, the inner cylinder 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 setting a water collection cavity 31 on the outside of the inner cylinder 1, the water collection cavity 31 has a certain water collection effect. Since the water guiding structure 2 is located inside the water collection cavity 31, the entire drainage is smoother, further improving the drainage efficiency and thus further saving energy.

[0130] It should be noted that the clothing handling device provided in this embodiment does not have an outer drum. Instead, a water collection chamber 31 is provided on the outside of the inner drum 1, and a water guiding structure 2, which communicates with the inner cavity of the inner drum 1, is provided within the water collection chamber 31. Water is directly discharged to the outside of the clothing handling device through the water guiding structure 2, eliminating the need for external driving force and saving energy and cost. Furthermore, since an outer drum is not required, washing water is saved, and the space occupied by the clothing handling device with this inner drum structure is reduced to a certain extent, enabling the clothing handling device to be miniaturized and occupy less space.

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.
