Description

Technical Field

[0001] This application relates to the field of clothing processing technology, and in particular to a clothing processing apparatus and a clothing processing device. Background Technology

[0002] With the development of the washing machine industry, people's requirements for healthy laundry are becoming increasingly prominent, and washing clothes by section or category is gradually becoming a trend. As a result, multi-tub washing machines, such as twin-tub and triple-tub washing machines, have emerged. In particular, triple-tub washing machines can separate adult clothes, underwear, and children's clothes for washing, making them more functional. Therefore, triple-tub washing machines are attracting more and more consumers' attention.

[0003] Current triple-drum washing machines add two smaller drums to the basic single-drum design. This results in either a larger overall size that occupies too much indoor space, or the smaller drums having insufficient capacity, leading to a poor user experience. Therefore, redesigning the layout of the main components within a triple-drum washing machine to expand its drum capacity while reducing its overall size and space requirements is a pressing issue that needs to be addressed.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] In view of this, the present application aims to provide a clothing processing device that can expand the multi-tube capacity of the clothing processing device and reduce the overall size and space occupation of the clothing processing device.

[0006] In a first aspect, embodiments of this application provide a garment processing device, comprising:

[0007] The enclosure has a left side wall and a right side wall;

[0008] The enclosure contains a large cylindrical assembly and at least one small cylindrical assembly, with the small cylindrical assembly located above the large cylindrical assembly; the left side wall and the right side wall both extend along a first vertical plane, wherein the first vertical plane is a vertical plane parallel to the central axis of the large cylindrical assembly;

[0009] The left and right reinforcing plates are fixed inside the box, and both the left and right reinforcing plates are parallel to the first vertical plane;

[0010] A left elastic connector and a right elastic connector are provided. The left reinforcing plate and the large cylinder assembly are connected through the left elastic connector, and the right reinforcing plate and the large cylinder assembly are connected through the right elastic connector.

[0011] The above arrangement allows the smaller tube assembly to be positioned as far as possible towards the left and right sides of the larger tube assembly. This increases the space available for the smaller tube assembly, thus increasing its volume and capacity, while simultaneously reducing the overall volume and space occupied by the larger tube assembly, all while maintaining a fixed overall height for the garment handling device. Furthermore, by installing left and right reinforcing plates inside the housing and suspending the larger tube assembly on these plates, the frame structure of the housing becomes more stable, providing more stable suspension support for the larger tube assembly and reducing any shaking or instability during operation.

[0012] In conjunction with the first aspect of this application, in an optional embodiment, the projection of the small drum assembly onto the horizontal plane is within the projection range of the large drum assembly onto the horizontal plane; the projections of the large drum assembly and the small drum assembly onto the first vertical plane overlap; and the projections of the small drum assembly and the left reinforcing plate or the right reinforcing plate onto the first vertical plane overlap. Through the above arrangement, the arrangement of the small drum assembly, the left reinforcing plate, and the right reinforcing plate is more compact, minimizing the vertical space occupied by the small drum assembly, the left reinforcing plate, and the right reinforcing plate without increasing the lateral width of the washing machine, thereby reducing the height of the washing machine and its overall volume.

[0013] In conjunction with the first aspect of this application, in an optional embodiment, the large drum assembly includes a first outer drum assembly, and the small drum assembly includes a second outer drum assembly; the first outer drum assembly includes a first front drum and a first rear drum, and the second outer drum assembly includes a second front drum and a second rear drum; the first front drum and the second front drum are configured as an integrally formed front drum assembly, and the first rear drum and the second rear drum are configured as an integrally formed rear drum assembly. The aforementioned integrally formed structure has high structural strength, is easy to process, has low manufacturing cost, and is beneficial for reducing the size of the washing machine.

[0014] In conjunction with the first aspect of this application, in an optional embodiment, the front cylinder assembly and the rear cylinder assembly are fixed together by fasteners, wherein there are several fasteners and they are spaced apart along the circumference of the front cylinder assembly or the rear cylinder assembly, thereby splicing the front cylinder assembly and the rear cylinder assembly into a stable whole, which facilitates the installation of components such as the inner cylinder.

[0015] In conjunction with the first aspect of this application, in an optional embodiment, both the left reinforcing plate and the right reinforcing plate have clearance notches for avoiding the fixing members. This avoids the fixing members, fixing lugs, and ribs at the connection between the front and rear drum assemblies, thereby further optimizing the spatial layout and preventing collisions between the drum assembly and the reinforcing plates caused by the shaking of the washing machine during operation.

[0016] In conjunction with the first aspect of this application, in an optional embodiment, both the left reinforcing plate and the right reinforcing plate have a body portion and a first flange portion located below the body portion. Both the body portion and the first flange portion are parallel to the central axis of the large drum assembly. The first flange portion extends relative to the body portion in a direction away from the casing. The first flange portion is used to connect the left elastic connector or the right elastic connector. This provides appropriate clearance space for the installation of the elastic connector, thereby facilitating a reduction in the width and height of the washing machine.

[0017] In conjunction with the first aspect of this application, in an optional embodiment, both the left reinforcing plate and the right reinforcing plate have a second flange portion located on the front and / or rear side of the body portion, the second flange portion extending relative to the body portion in a direction away from the housing, and the second flange portion being used for fixed connection with the housing.

[0018] In conjunction with the first aspect of this application, in an optional embodiment, the first front cylinder and the second front cylinder have equal first axial lengths, the second rear cylinder has a second axial length, and the first rear cylinder has a third axial length, wherein the first axial length is greater than the third axial length, and the third axial length is greater than the second axial length. By designing the lengths of each front and rear cylinder, the manufacturing and forming of the cylinder body and the installation of components are facilitated, while also maximizing the length of the large cylinder assembly and increasing its capacity.

[0019] In conjunction with the first aspect of this application, in an optional embodiment, the number of small cylinder assemblies is two, and the two small cylinder assemblies are symmetrically arranged with respect to the central axis of the large cylinder assembly. This facilitates balance and stability among the three rollers, reduces the use of counterweights, and lightens the overall weight of the machine.

[0020] In conjunction with the first aspect of this application, in an optional embodiment, the large drum assembly further includes a first inner drum located within the first outer drum assembly, and the small drum assembly further includes a second inner drum located within the second outer drum assembly. The first inner drum and the second inner drum are respectively driven to rotate by corresponding direct drive motors. This simplifies the drive structure, enhances overall performance, and achieves better washing results.

[0021] The garment processing device provided in this application embodiment has a left reinforcing plate and a right reinforcing plate fixedly installed inside the box. The left reinforcing plate is connected to the large tube assembly via a left elastic connector, and the right reinforcing plate is connected to the large tube assembly via a right elastic connector, thereby suspending the first outer tube assembly on the left and right reinforcing plates. Both the left and right reinforcing plates are parallel to the first vertical plane. In the prior art, the elastic connectors on both sides are usually directly connected to the top of the box, so that the elastic connectors extend obliquely from both sides of the large tube assembly towards the top of the box, occupying the top space of the large tube assembly. As a result, the small tube assemblies on both sides need to be arranged closer to the middle of the large tube assembly, which undoubtedly reduces the volume of the small tube assemblies. Compared with the prior art, this application can make the small tube assemblies on both sides as far away from the sides of the large tube assembly as possible. Thus, on the one hand, with a fixed overall height of the garment processing device, the arrangement space of the small tube assemblies is increased, thereby increasing the volume and capacity of the small tube assemblies. On the other hand, with a fixed volume and capacity of the small tube assemblies, the overall volume and space occupation of the garment processing device can be reduced. In addition, this application provides a left reinforcing plate and a right reinforcing plate inside the housing, and suspends the large cylinder assembly on the left and right reinforcing plates, making the frame structure of the housing more stable and providing a more stable suspension support for the large cylinder assembly, thereby reducing the degree of shaking or instability of the whole machine during operation.

[0022] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0044] like Figures 1-7 As shown, this disclosure provides a garment processing apparatus capable of washing or drying garments. Figure 1In the diagram, the X-direction arrow points to the left, the Y-direction arrow points forward, and the Z-direction arrow points upward. The clothing processing device in this embodiment includes at least three drums. For example, the clothing processing device can be a three-drum washing machine, which includes a housing 1 and a large drum assembly 2 and two small drum assemblies 3 disposed within the housing 1. The two small drum assemblies 3 are located on the left and right sides above the large drum assembly 2. The large drum assembly 2 includes a first outer drum assembly 20 and a first inner drum 23 located within the first outer drum assembly 20. The small drum assemblies 3 include a second outer drum assembly 30 and a second inner drum 33 located within the second outer drum assembly 30. Each outer drum assembly is fixedly disposed relative to the housing 1, and each inner drum is coaxially disposed with its corresponding outer drum assembly. Each inner drum can rotate within its corresponding outer drum assembly, thereby completing operations such as washing, rinsing, spin-drying, and drying. The large drum assembly 2 and the two small drum assemblies 3 are arranged in a triangular pattern. By setting up the large drum and the two small drums, it is possible to wash adult clothes, underwear, children's clothes, etc. separately. It is also possible to wash clothes separately according to the degree of soiling or the color of the clothes, thus realizing multi-purpose use. Users do not need to purchase multiple washing machines, which can reduce purchase costs, save space, and save washing time.

[0045] When a washing machine is operating, the inner drum rotates at high speed, generating strong centrifugal force. Without effective shock absorption measures, the washing machine will vibrate violently, and may even wobble or shift. Therefore, washing machine drums are usually equipped with elastic connectors, such as suspension springs. These springs absorb and buffer this vibration energy through their elastic deformation, keeping the machine relatively stable. The suspension springs also provide upward support to the drum, ensuring it maintains the correct posture and position during operation, preventing it from sagging or deforming due to its own weight or the centrifugal force generated by rotation. In addition, washing machine drums are usually equipped with shock-absorbing support structures, such as damping shock absorbers, to ensure smooth operation and reduce vibration and noise. Figure 2 As shown, a shock-absorbing support structure 7 is provided around the bottom of the first outer cylinder assembly 20. One end of the shock-absorbing support structure 7 is hinged to the first outer cylinder assembly 20, and the other end is hinged to the housing 1.

[0046] In some alternative embodiments, such as Figure 1 , Figure 2 As shown, the clothes handling device also includes counterweights 8. The counterweights 8 can be installed on both sides of the front of the drum assembly 2, or on the top of the cabinet 1, etc., as needed. The counterweights 8 can balance the centrifugal force when the drum washing machine rotates at high speed, making the washing machine run more smoothly.

[0047] In existing three-tub washing machines, the suspension springs typically connect one end to the left and right sides of the main tub and the other end to the top of the casing. This arrangement causes the suspension springs to extend at an angle from the sides of the main tub towards the top of the casing, occupying the top space of the main tub. Consequently, the two smaller tubs on either side need to be positioned closer to the center of the main tub. This inevitably reduces the volume of the two smaller tubs, resulting in a smaller capacity, given a fixed overall height of the washing machine. Therefore, how to design and arrange the main components within a three-tub washing machine to expand its tub capacity while reducing its overall size and space occupation has become a pressing issue.

[0048] Therefore, such as Figures 1-7 As shown, the garment processing apparatus of this embodiment includes:

[0049] Box 1 has a left side wall 11 and a right side wall 12;

[0050] The large cylindrical assembly 2 and at least one small cylindrical assembly 3 are located inside the housing 1, with the small cylindrical assembly 3 located above the large cylindrical assembly 2; the left side wall 11 and the right side wall 12 both extend along a first vertical plane, wherein the first vertical plane is a vertical plane parallel to the central axis of the large cylindrical assembly 2;

[0051] The left reinforcing plate 5 and the right reinforcing plate 6 are fixed inside the box 1, and both the left reinforcing plate 5 and the right reinforcing plate 6 are parallel to the first vertical plane;

[0052] Left elastic connector 41, right elastic connector 42, left reinforcing plate 5 and large cylinder assembly 2 are connected by left elastic connector 41, right reinforcing plate 6 and large cylinder assembly 2 are connected by right elastic connector 42. Left reinforcing plate 5 Right reinforcing plate 6 Left reinforcing plate 5 Right reinforcing plate 6 Left reinforcing plate 5 Right reinforcing plate 6 Left elastic connector 41 Right elastic connector 42 Left reinforcing plate 5 Left elastic connector 41 Right reinforcing plate 6 Right elastic connector 42.

[0053] The garment processing device provided in this application embodiment has a left reinforcing plate 5 and a right reinforcing plate 6 fixedly installed inside the housing 1. The left reinforcing plate 5 is connected to the large tube assembly 2 through a left elastic connector 41, and the right reinforcing plate 6 is connected to the large tube assembly 2 through a right elastic connector 42, thereby suspending the large tube assembly 2 on the left and right reinforcing plates. The left reinforcing plate 5 and the right reinforcing plate 6 are both parallel to the first vertical plane. Compared with the prior art, this application can maximize the placement of the small tube assembly 3 on the left and right sides of the large tube assembly 2. Thus, on the one hand, with a fixed overall height of the garment processing device, the arrangement space of the small tube assembly 3 is increased, thereby increasing the volume and capacity of the small tube assembly 3. On the other hand, with a fixed volume and capacity of the small tube assembly 3, the overall volume and space occupation of the garment processing device can be reduced. In addition, this application provides a left reinforcing plate 5 and a right reinforcing plate 6 inside the housing 1, and suspends the large cylinder assembly 2 on the left and right reinforcing plates, making the frame structure of the housing 1 more stable and providing a more stable suspension support for the large cylinder assembly 2, thereby reducing the degree of shaking or instability of the whole machine during operation.

[0054] Optionally, the left and right reinforcing plates are respectively adjacent to the left and right side walls of the housing 1, so that the left and right elastic connecting members 42 extend vertically on both sides of the large cylinder assembly 2 and do not occupy the top space of the large cylinder assembly 2. Those skilled in the art will understand that "adjacent" here means that the gap between the left reinforcing plate 5 and the right reinforcing plate 6 and the left side wall 11 and the right side wall 12 of the housing 1 is very small, so as to strengthen the frame or side wall of the housing 1 without occupying the internal space of the housing 1. The left reinforcing plate 5 and the right reinforcing plate 6 can also be in contact with the left side wall 11 and the right side wall 12 respectively, or the left reinforcing plate 5 and the right reinforcing plate 6 can also be installed on the left side wall 11 and the right side wall 12 respectively.

[0055] Optionally, the number of small drum components 3 is two. This embodiment is a three-drum washing machine, and the two small drum components 3 can better meet the washing needs of more refined partitioning. By setting left and right reinforcing plates, the large drum component 2 is suspended on the left and right reinforcing plates, so that the two small drum components 3 are set as far apart as possible from the left and right sides of the large drum component 2. In other optional embodiments, the number of small drum components 3 can also be one or more.

[0056] Alternatively, the left elastic connector 41 and the right elastic connector 42 may be springs, i.e., suspension springs.

[0057] In some alternative embodiments, such as Figure 2 , Figure 5As shown, the projections of the small drum assembly 3 on the horizontal plane are all within the projection range of the large drum assembly 2 on the horizontal plane; the projections of the large drum assembly 2 and the small drum assembly 3 overlap in the first vertical plane; the projections of the small drum assembly 3 and the left reinforcing plate 5 overlap in the first vertical plane, and the projections of the small drum assembly 3 and the right reinforcing plate 6 overlap in the first vertical plane. Through the above spatial layout of the large drum assembly 2, the small drum assembly 3, the left reinforcing plate 5, and the right reinforcing plate 6 within the housing 1, the two small drum assemblies 3 are moved as far away from the sides as possible, and the height of the left reinforcing plate 5 and the right reinforcing plate 6 is adapted to the height of the small drum assembly 3, thereby making the arrangement of the small drum assembly 3, the left reinforcing plate 5, and the right reinforcing plate 6 more compact. Without increasing the horizontal width of the washing machine, the vertical space occupied by the small drum assembly 3, the left reinforcing plate 5, and the right reinforcing plate 6 is minimized, thereby reducing the height of the washing machine and reducing the overall volume of the washing machine.

[0058] In some alternative embodiments, such as Figure 2 As shown, the large cylinder assembly 2 includes a first outer cylinder assembly 20, and the small cylinder assembly 3 includes a second outer cylinder assembly 30. The first outer cylinder assembly 20 includes a first front cylinder 21 and a first rear cylinder 22, and the second outer cylinder assembly 30 includes a second front cylinder 31 and a second rear cylinder 32. The first front cylinder 21 and the second front cylinder 31 form an integrally formed front cylinder assembly, and the first rear cylinder 22 and the second rear cylinder 32 form an integrally formed rear cylinder assembly. In other words, this application divides the three outer cylinders into front and rear cylinders respectively. The front cylinders of the three outer cylinders are integrally formed into one front cylinder, and the rear cylinders of the three outer cylinders are integrally formed into one rear cylinder. This integrally formed structure organically combines the three rollers together, resulting in enhanced structural strength, convenient processing, and low manufacturing cost. Optionally, both the front and rear drum assemblies are integral injection-molded parts, which are simple to manufacture and can also reduce the overall weight of the washing machine. On this basis, the two small drum assemblies 3 are directly supported on the large drum assembly 2. The two small drum assemblies 3 can achieve shock absorption and buffering by relying on the suspension spring structure and shock-absorbing support structure 7 set on the large drum assembly 2. The two small drum assemblies 3 can also operate normally without setting up a separate shock-absorbing support structure 7 and suspension spring structure. The reduction of support structure and suspension structure can make the layout of the three outer drum assemblies more compact, thereby reducing the size of the washing machine.

[0059] Optionally, the front cylinder assembly and the rear cylinder assembly are fixed together by fasteners, which are a plurality of fasteners spaced apart circumferentially along the front or rear cylinder assembly. By providing a plurality of fasteners (not shown) circumferentially along the front cylinder assembly (i.e., the rear cylinder assembly), the front and rear cylinder assemblies are joined into a stable whole, facilitating the installation of components such as the inner cylinder. Specifically, such as Figures 3-4As shown, several fixing lugs corresponding to the fixing members are spaced apart on the circumference of the front and rear cylinder assemblies, respectively, for mounting the fixing members. The fixing lugs on the front and rear cylinder assemblies correspond one-to-one, and the fixing members pass between the fixing lugs on the front and rear cylinder assemblies. Optionally, the fixing members can be detachable fixing members such as screws, bolts, studs, or retaining pins, thereby facilitating the disassembly and maintenance of the front and rear outer cylinders. In other optional embodiments, the front and rear cylinder assemblies can also be fixed using non-detachable fixing methods such as welding, fusion, or riveting, or using snap-fit ​​methods.

[0060] Optionally, such as Figure 2 As shown, the front cylinder assembly has a first connecting portion 311, located between the first front cylinder 21 and the second front cylinder 31, and extending along the length of the front cylinder assembly. The first connecting portion 311 achieves an integral connection between the first front cylinder 21 and the second front cylinder 31, and also provides support for the second front cylinder 31. Optionally, similar to the front cylinder assembly, the rear cylinder assembly may also have a third connecting portion (not shown), located between the first rear cylinder 22 and the second rear cylinder 32, and extending along the length of the rear cylinder assembly. The third connecting portion achieves an integral connection between the first rear cylinder 22 and the second rear cylinder 32, and also provides support for the second rear cylinder 32.

[0061] Further optional, such as Figure 5 As shown, the rear cylinder assembly has a first rib 221 and a second rib 222 located on both sides, between the first rear cylinder 22 and the two second rear cylinders 32, respectively. By setting the first rib 221 and the second rib 222, which extend along a second vertical plane, the second vertical plane is perpendicular to the central axis of the large cylinder assembly 2; that is, the first rib 221 and the second rib 222 are perpendicular to the central axis of the large cylinder assembly 2. The first rib 221 and the second rib 222 further strengthen the support for the second rear cylinders 32. The first rib 221 and the second rib 222 have a larger support contact surface, resulting in better support and reducing the vibration of the two small cylinder assemblies 3. Optionally, as... Figures 2-4 As shown, the first rib 221 and the second rib 222 are provided at the connection between the front cylinder assembly and the rear cylinder assembly. Specifically, they can be provided at the fixed lug position of the rear cylinder assembly, thereby simplifying the design of the injection mold for the rear cylinder assembly and making it easier to form and demold.

[0062] In some alternative embodiments, such as Figure 2 , Figure 7As shown, the structures of the left reinforcing plate 5 and the right reinforcing plate 6 are symmetrical, and the structures and dimensions of each part are the same. Therefore, the structure of the left reinforcing plate 5 and the right reinforcing plate 6 will be described below. Figure 7 The explanation will be based on the right reinforcing plate 6 as an example.

[0063] Both the left reinforcing plate 5 and the right reinforcing plate 6 have a body portion 61 and a first flange portion 62 located below the body portion 61. Both the body portion 61 and the first flange portion 62 are parallel to the central axis of the first outer drum assembly 20. The first flange portion 62 extends away from the housing 1 relative to the body portion 61 and is used to connect the left elastic connector 41 or the right elastic connector 42. By providing a first flange portion 62 recessed into the washing machine at the lower part of the reinforcing plate, the space between the reinforcing plate and the small drum assembly 3 is effectively utilized, providing appropriate clearance space for the installation of the elastic connector, thereby helping to reduce the width and height of the washing machine.

[0064] Optionally, such as Figures 3-4 As shown, the elastic connector is a spring, with hooks at both ends to facilitate connection with the reinforcing plate and the large cylinder assembly 2. Further optionally, as... Figure 7 As shown, the first flange portion 62 of the reinforcing plate includes a horizontal flange 621 and a vertical flange 622. That is, based on the inward horizontal flange 621, the first flange portion 62 further bends the end of the horizontal flange 621 to form a downward vertical flange 622, which makes it easier to hoist the spring and optimize the installation space. Specifically, a hook 65 can be provided on the horizontal flange 621, which provides space for the hook 65. A connecting ear 211 is provided on the first front drum 21 of the first outer drum assembly 20. One end of the elastic connector is hooked on the hook 65, and the other end is hooked on the connecting ear 211. A hanging hole 623 can also be provided on the vertical flange 622 at the position corresponding to the hook 65. The hook 65 is located on the outside of the hanging hole 623. One end of the spring passes inward over the vertical flange 622 and then outward through the hanging hole 623, thus hooking outward onto the hook 65. In this way, the installation space of the elastic connector is further optimized, which is conducive to reducing the overall size of the washing machine.

[0065] Further optionally, the structure of the left reinforcing plate 5 and the right reinforcing plate 6 also has a clearance notch 63 for avoiding the fastener. For example... Figure 7As shown, the clearance notch 63 is mainly located in the first flange portion 62. Because fixing lugs and fasteners are provided on the front and rear drum assemblies, interference may occur between the reinforcing plate, especially the first flange portion 62, and the fasteners and fixing lugs. Therefore, a corresponding clearance notch 63 is provided on the reinforcing plate to avoid interference with the fasteners, fixing lugs, and ribs at the connection between the front and rear drum assemblies, thereby further optimizing the spatial layout and preventing collisions with the reinforcing plate caused by the shaking of the drum assembly during washing machine operation. It is understood that the clearance notch 63 can be located at the vertical flange 622 of the first flange portion 62, or it can extend from the vertical flange 622 of the first flange portion 62 to the horizontal flange 621, or it can further extend to the body portion 61. The size and extension of the clearance notch 63 need to be determined based on the size of the fasteners and the degree of interference between the reinforcing plate and the fasteners and ribs.

[0066] Of course, in other alternative embodiments, the first flange 62 may only have a horizontal flange 621, and the spring may be directly hooked onto the hook 65 provided on the horizontal flange 621. This can be flexibly determined according to the specific installation requirements of the elastic connector and its space occupation.

[0067] In some alternative embodiments, such as Figure 7 As shown, both the left reinforcing plate 5 and the right reinforcing plate 6 have a second flange 64. The second flange 64 is located on the front and / or rear side of the main body 61. The second flange 64 is bent relative to the central axis of the main body 61 toward the first outer cylinder assembly 20. The second flange 64 is used for fixed connection with the housing 1. As the connection part between the reinforcing plate and the housing 1, the second flange 64 has several mounting holes to realize the fixed connection between the reinforcing plate and the housing 1.

[0068] In some optional embodiments, the first front cylinder 21 and the second front cylinder 31 have equal first axial lengths, the second rear cylinder 32 has a second axial length, and the first rear cylinder 22 has a third axial length, wherein the first axial length is greater than the third axial length, and the third axial length is greater than the second axial length. On the one hand, the equal lengths of the three front cylinders simplify the mold structure and facilitate the manufacturing of the front cylinder assembly. On the other hand, overall, the front cylinder assembly is longer than the rear cylinder assembly. The front cylinder assembly has a simple structure, and its longer length makes molding relatively easy. The rear cylinder assembly, however, requires the installation of more components, such as water valves and motors, making its structure more complex. Therefore, a shorter length for the complex rear cylinder assembly facilitates molding and mold structure design. Furthermore, the second rear cylinder 32 is smaller in volume and needs to provide space for the installation of components such as motors, water valves, drying channels, and cooling systems. The first rear cylinder 22 has a larger volume than the second rear cylinder 32. The installation of components such as motors can be achieved by providing recesses on the first rear cylinder 22, minimizing the impact on its length. Therefore, the length of the second rear cylinder 32 is set shorter than that of the first rear cylinder 22. Thus, by designing the lengths of each front and rear cylinder as described above, the manufacturing and forming of the cylinder body and the installation of components are facilitated. At the same time, the length of the large cylinder assembly 2 is increased as much as possible, thereby expanding the cylinder capacity of the large cylinder assembly 2.

[0069] In some optional embodiments, the two smaller cylinder assemblies 3 are symmetrically arranged with respect to the central axis of the larger cylinder assembly 2. That is, the two smaller cylinder assemblies 3 are symmetrically arranged with respect to the larger cylinder assembly 2. This arrangement is beneficial for the balance and stability among the three rollers, reduces the use of counterweights 8, and reduces the overall weight of the machine. It is understood that, correspondingly, the first connecting parts 311 on both sides, the third connecting parts on both sides, the first ribs 221 and the second ribs 222 on both sides, etc., are also symmetrically arranged with respect to the central axis of the larger cylinder assembly 2, and the elastic connectors and connecting ears 211 on both sides are also symmetrically arranged with respect to the central axis of the larger cylinder assembly 2, which will not be described in detail here.

[0070] In some optional embodiments, the first inner drum 23 and the second inner drum 33 are driven to rotate by corresponding direct drive motors (DD motors). Compared with the traditional belt drive structure, the three inner drums are driven by their own independent direct drive motors, which makes the structure simpler, the overall performance stronger, and the washing effect better.

[0071] The clothing handling device of this application strengthens the structural strength of the cabinet by setting a reinforcing plate in the three-drum washing machine and adjusting the layout of the suspension spring assembly, thereby optimizing the spatial layout of the three drums, which is conducive to increasing the drum capacity or reducing the size of the washing machine.

[0072] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
