[0061] This application provides a support component and a clothing treatment device, which can improve the corrosion resistance of the support component, thereby increasing the strength of the support component.

[0062] Specifically, please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of the clothing processing tube 20 and the support assembly 10 provided in the embodiments of this application; Figure 2 This is a schematic diagram of the structure of the support component 10 provided in the embodiments of this application; Figure 3 This is another structural schematic diagram of the support component 10 provided in the embodiments of this application; Figure 4 This is a schematic diagram of the structure of the support arm 111 and the connecting part 13 provided in the embodiments of this application.

[0063] The garment processing device in this embodiment can be a washing machine, a dryer, a garment care machine, etc. The following description will use a washing machine as the garment processing device in this embodiment.

[0064] The garment processing device of this embodiment includes a housing, a garment processing drum 20, and a support assembly 10. The housing comprises an outer shell and an internal support structure. The outer shell can be made of engineering plastic, possessing good insulation properties and impact resistance. A control panel for user operation is located on the front of the outer shell, integrating a touchscreen display or multiple operation buttons. Users can select various garment processing programs, such as regular washing, drying, and steam care, via the touchscreen display or by pressing the operation buttons. The control panel can also be used to start, pause, and stop programs. A door is also provided on the front of the outer shell, used to selectively open or close the opening of the garment processing drum 20.

[0065] The internal support structure can be made of high-strength metal alloy or plastic, providing a stable and robust structure that can reliably support the garment handling drum 20, ensuring its stability during operation. Shock-absorbing connection technology can be used between the internal support structure and the outer shell to effectively reduce vibration and noise generated by the garment handling device during operation.

[0066] In this embodiment, the laundry drum 20 is installed inside the washing machine, for example, on the internal support structure of the machine. The laundry drum 20 can be made of stainless steel to ensure sufficient strength to withstand the centrifugal force generated by high-speed rotation. The laundry drum 20 is generally hollow and cylindrical, and its internal space can be arranged according to washing needs to accommodate different volumes and types of laundry, such as sheets, clothes, and shoes. The inner wall of the laundry drum 20 is smoothed to effectively reduce wear and tear on clothes during the washing process.

[0067] In some of these embodiments, such as Figure 1 As shown, the clothes handling drum 20 includes a drum body 21 and a bottom cover 22. One end of the drum body 21 is open to facilitate the insertion and removal of clothes, while the other end is connected to the bottom cover 22 to form a space for accommodating clothes. The clothes handling drum 20 can rotate to realize the washing function of the clothes handling device. Exemplarily, the clothes handling device also includes a motor, which is driven by a support assembly 10, which is installed at the bottom cover 22 of the clothes handling drum 20. The transmission connection between the motor and the support assembly 10 can be through belt drive or direct connection via coupling, that is, direct or indirect transmission, to ensure that the motor can drive the support assembly 10 to rotate, thereby driving the clothes handling drum 20 to rotate stably. During the rotation of the clothes handling drum 20, the clothes are moved from bottom to top; under the action of gravity, the clothes fall from top to bottom. In this way, the clothes are dispersed, tumbled, and their posture changed under the combined action of the clothes handling drum 20 and gravity, thereby realizing the washing function.

[0068] Since the support component 10 inevitably comes into contact with water and detergent for a long time, the existing cast aluminum integral support component 10 is prone to corrosion under the long-term action of water and detergent, which affects the life and strength of the support component 10.

[0069] In this regard, this application provides a support component 10 with high corrosion resistance to improve the lifespan and strength of the support component 10.

[0070] Specifically, the support assembly 10 includes a bracket 11, a connecting shaft 12, and a connecting part 13. The bracket 11 is the main structural part of the support assembly 10 and consists of at least three support arms 111. That is, the number of support arms 111 is not limited; it can be three, four, or five, and no specific limitation is made here. For example, the support assembly 10 includes three support arms 111, one end of which is connected to the connecting shaft 12. The connection method can be welding, riveting, or other forms. Furthermore, the three support arms 111 are arranged at an angle of approximately 120°, forming a stable triangular shape. This angular distribution allows for even distribution of force, ensuring that the stress borne by each support arm 111 is relatively balanced when bearing the weight of the clothing handling drum 20 and the clothing inside and rotating, thereby ensuring the stability of the overall structure. It can be understood that when more than three support arms 111 are provided, the multiple support arms 111 can be arranged at approximately equal angles. For example, when four support arms 111 are provided, adjacent support arms 111 are arranged at 90°, thereby improving the overall strength of the bracket 11.

[0071] In some implementations, the bracket 11 is made of a rust-resistant material. In one embodiment, the bracket 11 is made of stainless steel, such as 304 stainless steel, 430 stainless steel, or 200 series stainless steel. Chromium in stainless steel spontaneously forms a dense and stable chromium oxide passivation film on its surface, effectively preventing water, detergent, and other potentially corrosive substances in the garment processing device from contacting the internal metal substrate. This allows the bracket 11 to maintain good corrosion resistance even in the long-term humid environment of the washing machine, where it is exposed to various chemical detergents, greatly reducing the possibility of corrosion and ensuring the strength and stability of the bracket 11. Simultaneously, stainless steel has relatively high toughness and plasticity, making it easy to manufacture the support component 10 into the required shape through stamping, bending, and other processing techniques, thus facilitating processing.

[0072] In another embodiment, the outer surface of the bracket 11 has a rust-proof coating, which can be selected from a zinc plating coating, a paint coating, and a phosphate coating to achieve the rust-proof function.

[0073] The zinc coating is applied to the surface of the bracket 11 by hot-dip galvanizing or electro-galvanizing. The zinc layer is tightly bonded to the base metal, forming a continuous covering. In the humid and chemically-laden environment of the washing machine, zinc has a lower electrode potential than base metals such as iron, and will preferentially corrode. Acting as a sacrificial anode, zinc protects the base metal bracket 11, effectively delaying the corrosion of the base metal and improving the overall corrosion resistance of the bracket 11.

[0074] Paint coatings are typically made of epoxy paint, polyurethane paint, etc., and consist of various components such as film-forming substances, pigments, and solvents. After the paint coating is applied to the surface of the bracket 11, it undergoes drying and curing processes to form a continuous and dense protective film, which isolates the bracket 11 from the outside air, moisture, and corrosive substances such as detergents that may come into contact with it, thereby achieving the purpose of rust prevention.

[0075] The phosphate coating is achieved through chemical phosphating, where a phosphating solution containing phosphoric acid and phosphates reacts chemically with the metal surface of the support 11 to form a phosphate conversion film, also known as the phosphate film. The phosphate film has a porous structure, which provides a good adhesion foundation for subsequent coating processes and also enhances the rust resistance of the metal, thus improving the corrosion resistance of the support 11.

[0076] In this embodiment, the connecting shaft 12 is connected to the junction of the three support arms 111. The connecting shaft 12 serves as the central rotating shaft 122 of the entire support assembly 10. Driven by a power device such as a motor, it drives the entire support assembly 10 to rotate, thereby driving the clothing processing drum 20 to rotate.

[0077] In some implementations, the connecting shaft 12 includes a bushing 121 and a rotating shaft 122. The bushing 121, as the part of the connecting shaft 12 structure directly connected to the support arm 111 of the support assembly 10, is welded to the junction of the three support arms 111. The rotating shaft 122 passes through the bushing 121, and the size of the rotating shaft 122 precisely matches the inner diameter of the bushing 121; the two can be connected by an interference fit. One end of the rotating shaft 122 is connected to a power source (such as a motor, connected to the rotating shaft 122 via belt drive, coupling, or other transmission methods) to receive power from the motor, thereby driving the entire support assembly 10 and the clothes processing drum 20 to rotate, realizing the washing and dehydration functions of the clothes processing device. The connecting shaft 12 can be made of the same material as the bracket 11, which will not be described further here.

[0078] In this embodiment, the connecting part 13 is used to connect the support assembly 10 and the clothing processing tube 20. The connecting part 13 can also be made of the same material as the bracket 11.

[0079] In some embodiments, the connecting part 13 is connected to the end face of the support arm 111 away from the connecting shaft 12. The connection method can include welding, riveting, screw connection, etc. In some embodiments, the connecting part 13 is welded to the end face of the support arm 111 away from the connecting shaft 12, which makes the welding operation relatively intuitive and convenient. It should be noted that, due to differences in products, the required bracket shape or type may vary. The end face 13a of the support arm 111 away from the connecting shaft 12 can be a U-shaped end face, a Z-shaped end face, a plate-like end face, a closed end face (i.e., the end face formed by the closure of the far end of the support arm 111), or an open end face, etc. This is not specifically limited, as long as it is the end face of the support arm 111 away from the connecting shaft. It should be noted that the end face can be flat or curved, without specific limitations.

[0080] In some implementations, the end face of the support arm 111 can be designed as a planar structure, which facilitates surface treatment during machining, ensuring its flatness and smoothness, and providing a good foundation for subsequent welding processes. For example, during the manufacturing process, the end face of the support arm 111 can be machined to the required precision through simple machining processes such as milling and grinding, resulting in a tighter fit between the connecting part 13 and the support arm 111 during welding, which helps to improve welding quality.

[0081] Meanwhile, from an assembly perspective, the welding of the connecting part 13 to the end face facilitates quick and accurate positioning and connection with the corresponding connecting surface of the garment handling cylinder 20 during the assembly of the garment handling device. Workers can clearly see the welding position and the orientation of the connecting part 13, reducing assembly errors caused by factors such as obstructed viewpoints and improving the efficiency of the entire assembly process.

[0082] Furthermore, the connection between the connecting part 13 and the clothes handling drum 20 can be achieved through fasteners, such as screws or bolts. In one embodiment, the clothes handling drum 20 consists of a drum body 21 and a drum bottom cover 22. The drum body 21 has a protruding edge 211 that protrudes from the drum bottom cover 22. Since the protruding edge 211 itself is relatively thin, it is prone to deformation when bearing the overall weight of the clothes handling drum 20 and the forces generated during the operation of the washing machine, thereby affecting the connection stability.

[0083] Therefore, in some implementations, the connecting part 13 is designed as a block shape, such as a regular block like a cuboid or cube, or other irregular blocks, and the thickness of the connecting part 13 along the length of the support arm 111 is not less than 5 mm. This design, on the one hand, enhances the structural strength of the connecting part 13 itself, enabling it to better bear the load from the clothing handling tube 20 during connection; on the other hand, when the thickness of the connecting part 13 is not less than 5 mm, it provides a sufficiently long thread engagement length when connected to fasteners, allowing screws or bolts to be fully screwed in, significantly increasing the friction and engagement force between the threads, thereby improving the connection strength between the support assembly 10 and the clothing handling tube 20.

[0084] Furthermore, the connecting part 13 is provided with at least one connecting hole 131, which is used to connect with the garment processing drum 20, and the extended line of the axis of the connecting hole 131 intersects the axis of the garment processing drum 20. Specifically, the connecting part 13 is connected to the protruding edge 211 of the garment processing drum 20, and the extended line of the axis of the connecting hole 131 is substantially perpendicular to the axis of the garment processing drum 20, with an angle of 90°±10°. Thus, during the rotation of the garment processing drum 20, the centrifugal force it generates will have different effects depending on the setting angle of the axis of the connecting hole 131. Compared with the connection method where the axis of the connecting hole 131 is parallel to the axis of the garment processing drum 20, this embodiment can optimize the force state of the connecting part 13 by utilizing the principle of force decomposition. When the garment processing drum 20 rotates at high speed and generates centrifugal force, this centrifugal force can be decomposed into a component force perpendicular to the connection surface between the connecting part 13 and the garment processing drum 20 and a component force along the tangential direction of the connection surface. The vertical component of the force acts as a clamping force between the connecting part 13 and the clothes handling drum 20, increasing the friction between them and effectively preventing relative sliding of the connecting part 13. For example, during the spin-drying process of the washing machine, the clothes handling drum 20 rotates at high speed, generating a large centrifugal force. At this time, the vertical component of the force significantly increases the friction between the connecting part 13 and the protruding edge 211 of the clothes handling drum 20, ensuring that the connecting part 13 will not be displaced due to centrifugal force.

[0085] While the component of the force along the tangent direction of the connection surface generates a tensile force on the connection part 13, the structural design of the connection part 13 is more suitable for withstanding this type of axial tensile force. When a bolted connection is used, the axial tensile strength of the bolt can effectively resist this component of the force. Compared with parallel connections where the bolt mainly bears shear force, the reliability of the connection is greatly improved.

[0086] In some implementations, the end face of the connecting portion 13 away from the support arm 111 is configured as an arc-shaped surface, which matches the connecting surface of the garment processing tube 20. Specifically, the protruding edge 211 of the garment processing tube 20 has an arc-shaped connecting surface, and the arc-shaped surface of the connecting portion 13 can fit tightly against the connecting surface of the protruding edge 211. This fitting method greatly increases the contact area between the connecting portion 13 and the garment processing tube 20. Compared with the traditional planar connection method, when the arc-shaped surface is fitted, the contact points are more evenly distributed, making the force transmission more stable and the connection more secure.

[0087] In one embodiment, see Figure 5 and Figure 6 The connecting part 13 includes a first plate 134, a second plate 135, and a connecting post 136. The first plate 134 is connected to the end face 13a of the support arm 111 away from the connecting shaft 12. Exemplarily, the first plate 134 is welded to the end face 13a of the support arm 111 away from the connecting shaft 12. Before welding, the welding area between the end face of the support arm 111 and the first plate 134 can be ground and cleaned to remove surface oil, rust, and other impurities to ensure welding quality.

[0088] The second plate 135 has a second through hole 1303, and the connecting post 136 is connected to the second wall 1352. The connecting post 136 is provided with a connecting hole 131, and the central axis of the second through hole 1303 and the central axis of the connecting hole 131 are on the same straight line. This arrangement facilitates the fastening of the fasteners of the garment handling device to the garment handling cylinder. In this embodiment, it is understood that in the actual manufacturing process, due to the existence of processing errors, even if there is a certain deviation in the central axis, as long as it is within a reasonable tolerance range (e.g., a radial deviation of ±0.5mm), they can still be considered to be on the same straight line.

[0089] In some embodiments, the second plate 135 is connected to the first plate 134 and forms a mounting groove 1301 with the first plate 134. The second plate 135 includes a first wall 1351 and a second wall 1352 connected at an angle. The connection method can be a rounded corner connection or a right-angle connection. A rounded corner connection can effectively reduce stress concentration and improve the structural strength of the second plate 135; a right-angle connection facilitates processing and assembly, resulting in higher production efficiency. The end of the first wall 1351 away from the second wall 1352 is connected to the first plate 134. The connection method can be welding, bolting, riveting, or integral installation. In some embodiments, the first plate 134 is provided with a first through hole 1302. The central axis of the first through hole 1303 must also be on the same straight line as the central axis of the connecting hole 131 of the connecting post 136 and the central axis of the second through hole 1303 to ensure that the fastener can pass smoothly and achieve a tight connection. Furthermore, by providing a first through hole 1302 in this embodiment, at least a portion of the fastener can be passed through the first through hole 1302, and then the fastener can be welded to the first through hole 1302. This improves the connection strength between the connecting part 13 and the support assembly 10, thereby improving the connection strength between the entire support assembly 10 and the clothing handling tube 20. The design that the central axes of the first through hole 1302, the connecting hole 131, and the second through hole 1303 are on the same straight line facilitates the insertion and tightening of the fastener. During the assembly process, workers can quickly and accurately pass the fasteners through each hole, avoiding assembly difficulties caused by misalignment of the holes, reducing assembly difficulty, and improving assembly accuracy and efficiency.

[0090] Similarly, in the actual manufacturing process, due to the existence of processing errors, even if there is a certain deviation between the central axes of the first through hole 1302, the second through hole 1303 and the connecting hole 131, as long as they are within a reasonable tolerance range (e.g., a radial deviation of ±0.5mm), they can still be considered to be on the same straight line.

[0091] The connecting post 136 is installed within the mounting groove 1301 formed by the first plate 134 and the second plate 135. The connecting post 136 can be connected to the second wall 1352 by welding, riveting, or threading. The connecting post 136 has a connecting hole 131 for fastening to the garment handling tube 20.

[0092] In another embodiment, please refer to Figure 7 , Figure 8 and Figure 9The connecting part 13 includes a connecting body 137 and a connecting post 136. The connecting body 137 is an important component of the connecting part 13, and it mainly includes a connecting plate 1371 and a surrounding plate 1372. The connecting plate 1371, as the main load-bearing part of the connecting body 137, can be made of high-strength metal material to ensure good strength and toughness.

[0093] The surrounding plate 1372 surrounds the periphery of the connecting plate 1371 and is welded to the end face 13a of the support arm 111 away from the connecting shaft 12. The surrounding plate 1372 and the connecting plate 1371 together form the mounting cavity 1304, forming a relatively closed spatial structure, which enhances the overall rigidity of the connecting part 13.

[0094] Specifically, the structure of the enclosure 1372 can include two forms. One form includes three folded plates, which are respectively connected to the three sides of the connecting plate 1371 to form a semi-enclosed mounting cavity 1304; the other form includes four folded plates, which are respectively connected to the four sides of the connecting plate 1371 to enclose and form an open mounting cavity 1304.

[0095] The connection methods between the folded plates can include bending, welding, riveting, and integrated installation.

[0096] In this embodiment, the connecting post 136 is connected to the connecting plate 1371 and installed within the mounting cavity 1304. The connecting post 136 can be connected to the connecting plate 1371 by welding or riveting. The connecting post 136 has a connecting hole 131, which allows the connecting post 136 to be reliably connected to the garment processing cylinder 20 via fasteners, ensuring a stable connection between the two during operation of the garment processing device.

[0097] In yet another embodiment, please refer to Figure 10 The connecting part 13 includes a first connecting block 132 and a second connecting block 133.

[0098] The first connecting block 132 and the second connecting block 133 are welded side-by-side to the end face 13a of the support arm 111 away from the connecting shaft 12. Thus, the connecting portion 13 forms a relatively wide connecting area on the support arm 111. This side-by-side welding method can distribute the force borne by the connecting portion 13 in the width direction, especially various forces generated during the operation of the garment handling drum 20, such as centrifugal force and vibration forces. When the garment handling drum 20 rotates at high speed, the side-by-side connecting blocks can jointly bear these forces, avoiding loosening or damage to the connection due to force concentration, and improving the overall load-bearing capacity and stability of the connecting portion 13.

[0099] Alternatively, the first connecting block 132 and the second connecting block 133 are welded at intervals to the end face 13a of the support arm 111 away from the connecting shaft 12, thus leaving a certain gap between the first connecting block 132 and the second connecting block 133. The connecting part 13 may undergo slight deformation under the action of force, and the gap design can provide additional deformation space for the connecting part 13, avoiding excessive stress concentration.

[0100] Furthermore, the wall of the connecting hole 131 extends toward the connecting shaft 12 and partially exceeds the end face of the support arm 111 away from the connecting shaft 12. In this way, a sufficiently long connection area can be provided for the fastener to enhance the stability of the connection.

[0101] When the connecting hole 131 extends beyond the end face of the support arm 111, when using fasteners (such as bolts and screws) for connection, it can increase the contact area between the fastener and the connecting hole 131, improve the friction, and thus better resist various forces generated by the clothing treatment drum 20 during operation (such as centrifugal force, vibration force, etc.), prevent loosening and displacement due to weak connection, and ensure the reliability of the connection.

[0102] In some implementations, the edge of the connecting hole 131 at the end away from the support arm 111 is set as a bevel. The bevel design has a centering function and facilitates the installation of fasteners.

[0103] The presence of this bevel allows the fastener to be automatically adjusted to a certain extent during the assembly process, even if there is a certain positional deviation, so that it can better match the connecting hole 131 and reduce connection problems caused by assembly errors.

[0104] Please see Figure 11 , Figure 11 This is a schematic diagram of the structure of the support assembly 10 after being cut open along the cross-section of a support arm 111, as provided in an embodiment of this application.

[0105] In this embodiment, the upper surface portion of the support arm 111 protrudes upward to form a protrusion 1111, and the length of the protrusion 1111 is the same as the length of the support arm 111.

[0106] The protrusion 1111 can be formed through a bending process. The protrusion 1111 formed by the bending process can significantly increase the strength of the support arm 111. From the perspective of mechanical principles, when the washing machine is in operation, the support assembly 10 bears external forces such as the gravity of the clothes handling drum 20 and the centrifugal force generated by rotation. The protrusion 1111 is equivalent to adding a three-dimensional reinforcing structure on the basis of the planar structure of the support arm 111, thereby improving the overall strength of the support arm 111.

[0107] Furthermore, the upper surface of the protrusion 1111 is a smooth surface. During assembly, the support assembly 10 needs to be placed in the mounting groove of the bottom cover 22. When the smooth protrusion 1111 on the support arm 111 contacts the inner wall of the mounting groove of the bottom cover 22, the smooth surface can minimize the unevenness and gaps on the surface, allowing the two to make close contact, thereby helping to improve the stability of the entire assembly structure.

[0108] In some embodiments, the support arm 111 has flanges 1112 on both sides of its width direction, and the two flanges 1112 are located on both sides of the protrusion 1111. The flange structure 1112 can also improve the strength of the support arm 111. From a structural mechanics perspective, the flanges 1112 on both sides of the support arm 111 are equivalent to adding additional reinforcing ribs, which can effectively resist the external forces borne by the support arm 111 in the width direction, such as the lateral forces generated during the rotation of the clothing handling drum 20 and the lateral forces caused by possible eccentricity.

[0109] In some embodiments, in the width direction of the support arm 111, the width of the protrusion 1111 is equal to the sum of the distances from the two flanges 1112 to the protrusion 1111, i.e., L = L1 + L2 (where L represents the width of the protrusion 1111, L1 represents the distance from one flange 1112 to the protrusion 1111, and L2 represents the distance from the other flange 1112 to the protrusion 1111). This dimensional relationship, on the one hand, ensures a more reasonable and balanced force distribution among the various components of the support arm 111 from a structural strength perspective. The arrangement of the protrusion 1111 and flanges 1112 according to the aforementioned proportional relationship allows the entire support arm 111 to evenly distribute the force to various parts for bearing load when subjected to external forces, fully utilizing the strength-enhancing effects of the protrusion 1111 and flanges 1112, and preventing structural damage due to excessive stress on any one part.

[0110] On the other hand, from an aesthetic point of view, the aforementioned size limitation makes the overall shape of the support arm 111 more regular and harmonious, giving people a simple and symmetrical beauty, which meets the requirements of modern home appliances for exquisite and beautiful appearance design.

[0111] Furthermore, the cross-sectional shape of the support arm 111 is axially symmetrical about the centerline of the protrusion 1111, and the cross-sectional shape is approximately "U"-shaped. This axially symmetrical structure gives the support arm 111 better symmetry and stability under stress. Regardless of the direction from which external force acts on the support arm 111, the corresponding structures on its left and right sides can evenly distribute and transfer stress about the centerline of the protrusion 1111 as the axis of symmetry, avoiding problems such as uneven stress and localized deformation that may occur due to structural asymmetry.

[0112] Furthermore, the width of the support arm 111 gradually decreases in the direction from the connecting shaft 12 toward the connecting portion 13. In this embodiment, the support arm 111, while ensuring sufficient strength to withstand the various forces acting on the garment handling tube 20, effectively saves material by gradually varying its width. At the end near the connecting shaft 12, where it primarily bears the torque transmitted from the connecting shaft 12 and distributes the force throughout the support arm 111, the width requirement is relatively high, so the initial width of the support arm 111 is relatively large. As it extends toward the connecting portion 13, the force is gradually dispersed and transmitted, and the width requirement for the support arm 111 decreases accordingly, thus its width gradually decreases.

[0113] The aforementioned gradually narrowing support arm 111 structure not only does not weaken the overall strength of the support arm 111, but also reduces the amount of material used and lowers the production cost while meeting the mechanical performance requirements through reasonable structural optimization. It also reduces the overall weight of the support assembly 10.

[0114] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
