Description

Technical Field

[0001] The present application relates to the technical field of clothing processing, and more particularly, to a vibration damping device and a clothing processing apparatus. Background Art

[0002] Common clothing processing equipment, such as pulsator washing machines, typically consists of a housing and a drum assembly housed within the housing. The drum assembly comprises an outer drum and an inner drum rotatably mounted within the outer drum. The outer drum is suspended within the housing via a vibration damping device consisting of several suspension rods. During washing and dehydration, the inner drum rotates relative to the outer drum, interacting with the laundry and wash water to achieve the desired cleaning or dehydration effects, while the suspension rods dampen vertical vibrations. However, due to uneven loads, the drum assembly can swing significantly under the influence of eccentric forces. This is particularly true during the dehydration startup phase, when the drum assembly experiences the greatest vibration displacement and is prone to impacting the housing.

[0003] To this end, related technologies incorporate a vibration damping device between the housing and the outer drum. This device absorbs and releases some of the vibration energy, reducing the drum assembly's maximum vibration displacement during dehydration startup and preventing the drum assembly from striking the housing. However, the damping device is connected to the housing via a suspension rod, which exerts force on the device. This can lead to fatigue failure due to uneven force distribution, shortening the device's service life. Utility Model Content

[0057] Figure 1 This is a schematic top view of the structure of a clothes processing device according to an embodiment of the present application. Figure 2 for Figure 1 The cross-sectional view of the laundry processing apparatus along the direction AA is shown, Figure 3 Schematic diagram of the structure of a vibration reduction device according to an embodiment of the present application.

[0058] See Figures 1 to 3 The present invention provides a laundry processing device 1000, comprising a housing 200, a drum assembly 300, and a vibration damping device 100. The laundry processing device 1000 may be a laundry processing device, such as a pulsator washing machine or a drum washing machine. For ease of description, the embodiments of the present invention are described using the pulsator washing machine as an example.

[0059] The housing 200 is typically formed by bending sheet metal and includes an interior space with an open end and a workbench covering the open end. The interior space can house other components of the pulsator washing machine, such as the circuitry, air duct structure, drive mechanism, and drainage assembly. A detergent box can be located at the front of the workbench. The housing 200 can be a hollow rectangular parallelepiped or a hollow cylinder. The inner periphery of the housing 200 typically has four corners, each with a corner panel 201.

[0060] The drum assembly 300 is disposed within the housing 200. A mounting base 301 is provided at the bottom of the drum assembly 300. For a pulsator washing machine, the axial direction of the drum assembly 300 is aligned with the height of the housing 200. For a drum washing machine, the axial direction of the drum assembly 300 intersects the height of the housing 200. For a front-loading washing machine, the axial direction of the drum assembly 300 intersects with the height of the housing 200. Taking a pulsator washing machine as an example, the drum assembly 300 comprises an outer drum and an inner drum rotatably disposed within the outer drum. The inner drum is hollow to form a washing chamber. Through holes are provided in the circumferential wall of the inner drum, through which wash water is discharged into the outer drum. A wastewater outlet is provided at the bottom of the outer drum, and wash water is discharged out of the machine through a drain assembly connected to the outlet. The top of the drum assembly 300 is provided with an access opening connected to the washing chamber, through which laundry is placed into the washing chamber for washing. A corresponding door is provided on the housing 200 to seal the access opening of the drum assembly 300 during washing, thereby creating a sealed space for the washing chamber.

[0061] A pulsator washing machine is a type of washing machine in which a motor drives the pulsator to rotate, causing the clothes to tumble up and down with the water. Driven by the pulsator, the water in the drum assembly 300 forms alternating left-hand and right-hand vortices, which rotate and tumble the clothes, thereby achieving both cleaning and dehydration. During the washing and dehydration process, the pulsator's rotational speed gradually increases. The eccentric load caused by the imbalance of the clothes gradually increases with the speed, and the drum assembly 300 inevitably vibrates. This is especially true during the dehydration startup phase. When the fundamental frequency of the excitation force corresponding to the pulsator's rotational speed approaches the natural frequency of the entire machine, the drum assembly 300 resonates, significantly increasing its amplitude. This means that the lateral vibration displacement of the drum assembly 300 is maximized, making it more likely to impact the housing 200. Therefore, a vibration damping device 100 is required to reduce the vibration displacement of the drum assembly 300.

[0062] The vibration damping device 100 is connected between the housing 200 and the barrel assembly 300. More specifically, the vibration damping device 100 is suspended between the angle plate 201 of the housing 200 and the mounting base 301 at the bottom of the barrel assembly 300. Since the housing 200 is relatively stationary, one end of the vibration damping device 100 is connected to the angle plate 201 of the housing 200 via the suspension rod 3, while the other end of the vibration damping device 100 is connected to the top of the barrel assembly 300. The end of the suspension rod 3 away from the angle plate 201 is connected to the mounting base 301 at the bottom of the barrel assembly 300, thereby providing effective damping force to prevent the barrel assembly 300 from colliding with the housing 200. However, at the connection between the vibration damping device 100 and the suspension rod 3, the vibration damping device 100 is subjected to the force exerted by the suspension rod 3, which can easily lead to fatigue failure due to uneven force, thus affecting the service life of the vibration damping device 100.

[0063] To this end, the vibration reduction device 100 provided in the embodiment of the present application can make the part of the vibration reduction device 100 connected to the suspension rod bear the force evenly, reduce the possibility of fatigue failure of the vibration reduction device 100, and increase the service life of the vibration reduction device 100.

[0064] Figure 4 This is a schematic structural diagram of a vibration reduction device according to an embodiment of the present application. Figure 5 Schematic diagram of the exploded structure of a vibration reduction device according to an embodiment of the present application.

[0065] See Figure 4 and Figure 5 , an embodiment of the present application provides a vibration reduction device 100, including a first moving part 1, a second moving part 2 and a suspension rod 3.

[0066] The first moving part 1 includes a first main body 11. The first moving part 1 can be a plastic part made of wear-resistant materials such as nylon and polyoxymethylene, which is light in weight and convenient for mass production.

[0067] The second moving member 2 includes a second main body 21 and a second connecting portion 22 connected to the second main body 21. The second main body 21 is pivotally connected to the first main body 11. The second connecting portion 22 includes a main body 221 having a through hole 220. The second connecting portion 22 is mounted on the outer periphery of the boom through the through hole 220. The first elastic portion and the second elastic portion of the main body 221 located on both sides of the center line L connecting the second main body 21 and the through hole 220 are both capable of elastic deformation. The second moving member 2 can be a plastic part made of a wear-resistant material such as nylon or polyoxymethylene. It is lightweight and easy to mass produce.

[0068] In the embodiment of the present application, the first main body 11 of the first moving part 1 is pivotally connected to the second main body 21 of the second moving part 2, so that the second moving part 2 and the first moving part 1 can rotate relative to each other within a preset angle to generate a damping force. The second connecting portion 22 of the second moving part 2 is sleeved on the outer peripheral side of the suspension rod 3 through the through hole 220, and the suspension rod 3 is used to be connected to the housing 200. In this way, when the clothing processing device 1000 is in the dehydration startup stage, the drum assembly 300 swings greatly under the action of eccentric centrifugal force to generate vibration, and the vibration reduction device 100 absorbs and releases a part of the vibration energy by generating a damping force through the relative rotation of the first moving part 1 and the second moving part 2 within a preset angle, thereby reducing the lateral vibration displacement of the drum assembly 300. Among them, the second connecting portion 22 of the second moving part 2 is sleeved on the outer peripheral side of the suspension rod 3, and the second connecting portion 22 is subjected to the force applied by the suspension rod 3 and is easily deformed.

[0069] To this end, the second connecting portion 22 in this embodiment includes a main body 221 having a through hole 220. The second connecting portion 22 is sleeved on the outer periphery of the suspension rod 3 through the through hole 220. The first elastic portion and the second elastic portion of the main body 221 located on both sides of the center line L between the second main body 21 and the through hole 220 are both capable of elastic deformation. The connection between the suspension rod 3 and the second connecting portion 22, i.e., the position of the main body 221 located on both sides of the center line L, is a force-bearing area. The force-bearing area is provided with the first elastic portion and the second elastic portion located on both sides of the center line L. When vibration occurs, the suspension rod 3 will act on this force-bearing area repeatedly and cyclically. Because the first elastic portion and the second elastic portion in this force-bearing area are both capable of elastic deformation, they will not be deformed or even damaged due to stress concentration. In this way, the second connecting portion 22 is less likely to suffer fatigue failure, thereby increasing the service life of the vibration reduction device 100.

[0070] In one example, if Figure 3 As shown, the vibration damping device 100 also includes a vibration damping sleeve 4. The upper end of the suspension rod 3 is connected to the corresponding corner plate 201 of the box body 200 via a fixing member. The lower end of the suspension rod 3 is connected to the vibration damping sleeve 4, and the vibration damping sleeve 4 is fixedly connected to the mounting seat 301 at the bottom of the drum assembly 300. The vibration damping sleeve 4 is provided with a spring assembly 41 and a spring seat 42 for fixing the spring assembly 41. This can reduce the lateral vibration displacement of the drum assembly 300 during dehydration startup and prevent the drum assembly 300 from colliding with the box body 200. In one example, of the four corner plates 201 of the box body 200, two corner plates 201 located on the diagonal line are each provided with a vibration damping device 100. In another example, each of the four corner plates 201 of the box body 200 is provided with a vibration damping device 100.

[0071] According to the embodiment of the present application, the vibration reduction device 100 includes a suspension rod 3, a first moving member 1 and a second moving member 2. The first main body 11 of the first moving member 1 is pivotally connected to the second main body 21 of the second moving member 2 so that the first moving member 1 and the second moving member 2 can rotate relative to each other within a preset angle to generate a damping force, thereby absorbing and releasing a portion of the vibration energy when the cylinder assembly 300 starts to dehydrate, reducing the vibration displacement of the cylinder assembly 300, and preventing the cylinder assembly 300 from hitting the box due to excessive amplitude. In addition, the second connecting portion 22 includes a main body 221 having a through hole 220. The second connecting portion 22 is sleeved on the outer peripheral side of the suspension rod 3 through the through hole 220. The first elastic portion and the second elastic portion of the main body 221 located on both sides of the center line L between the second main body 21 and the through hole 220 can both undergo elastic deformation and will not be deformed or even damaged due to stress concentration, thereby reducing the possibility of fatigue failure of the second connecting portion 22 and improving the service life of the vibration reduction device 100.

[0072] Figure 6 This is a schematic structural diagram of the vibration reduction device according to an embodiment of the present application from another angle. Figure 7for Figure 6 The structural diagram of the second moving part in the vibration reduction device shown in FIG. Figure 8 for Figure 7 Schematic diagram of the locally enlarged structure of area B in the middle.

[0073] In some embodiments, the main body 221 includes an inner peripheral structure 2211 and an outer peripheral structure 2212, the inner peripheral structure 2211 forms a through hole 220, and the outer peripheral structure 2212 is spaced apart on the outer peripheral side of the inner peripheral structure 2211. A plurality of reinforcing ribs 2213 are connected between the inner peripheral structure 2211 and the outer peripheral structure 2212, and a through groove is formed between two adjacent reinforcing ribs 2213.

[0074] See Figure 7 and Figure 8 When the wall thickness of the through hole 220 is too thick, elastic deformation is not easy to occur, and the suspension rod 3 is easy to get stuck when moving in the through hole 220. When the wall thickness of the through hole 220 is too thin, the strength is insufficient, and the suspension rod 3 is easy to break the through hole 220 when moving in the through hole 220. Therefore, a reinforcing rib 2213 is connected between the inner peripheral structure 2211 and the outer peripheral structure 2212 of the second connecting part 22, and a through groove is formed between two adjacent reinforcing ribs 2213. The through groove can thin the wall thickness of the through hole 220, increase the deformable amount of the side of the through hole 220, prevent the suspension rod 3 from getting stuck when moving in the through hole 220, enhance the fatigue resistance of the side of the through hole 220 to long-term deformation, and the reinforcing rib 2213 can increase the structural strength of the side of the through hole 220, prevent the through hole 220 from being broken by the suspension rod 3, and further extend the service life of the vibration damping device 100.

[0075] In some embodiments, the plurality of reinforcing ribs 2213 and the plurality of through slots are located on both sides of the center line L, and both the first elastic portion and the second elastic portion include through slots.

[0076] See again Figure 8 The second connecting part 22 is sleeved on the outer peripheral side of the hanger 3 through the through hole 220. The connection between the hanger 3 and the second connecting part 22, that is, the position of the main body 221 on both sides of the center line L is the force-bearing area. The force-bearing area is provided with a first elastic part and a second elastic part located on both sides of the center line L. When vibration occurs, the hanger 3 will act on the force-bearing area repeatedly. A plurality of reinforcing ribs 2213 and a plurality of through grooves are located on both sides of the center line L. The first elastic part and the second elastic part both include through grooves, which can enable the first elastic part and the second elastic part on both sides of the center line L to undergo elastic deformation, and can increase the structural strength and deformability of the side around the through hole 220, thereby enhancing the fatigue resistance of the side around the through hole 220 to long-term deformation, and will not be deformed or even damaged due to stress concentration, further improving the service life of the vibration damping device 100.

[0077] In some embodiments, a transition portion 223 is connected between the second main body portion 21 and the peripheral structure 2212 , and a portion of the peripheral structure 2212 corresponding to the through groove is indirectly connected to the transition portion 223 .

[0078] like Figure 8 As shown, a transition portion 223 is connected between the second main body portion 21 and the peripheral structure 2212, and a portion of the peripheral structure 2212 corresponding to the through groove is directly connected to the transition portion 223 so that the basic connection strength requirements are met between the second main body portion 21 and the peripheral structure 2212, while the other portion of the structure is indirectly connected to the transition portion 223, which can increase the elastic deformation capacity of the force-bearing area on both sides of the center line L, and further enhance the fatigue resistance of the long-term deformation of the peripheral side of the through hole 220.

[0079] In some embodiments, the peripheral structure 2212 , the plurality of reinforcing ribs 2213 , and the plurality of through slots are symmetrically arranged relative to the center line L.

[0080] See again Figure 8 In one example, the outer contour line of the cross section of the main body 221 along a direction perpendicular to the central axis of the through hole 220 includes a semicircular arc, a first straight line segment tangent to both ends of the semicircular arc, and a second straight line segment connecting the two first straight line segments, and the length of the first straight line segment is greater than the radius of the through hole 220, and the through hole 220 is arranged concentrically with the semicircular arc. Compared with the technical solution in which the main body 221 is a whole circular ring, the main body 221 occupies less space and is more easily compatible with smaller clothing processing equipment. The connection points of the semicircular arc, the first straight line segment, and the second straight line segment are connected by rounded corners to prevent the corners from scratching the operator. In addition, the peripheral structure 2212, the multiple reinforcing ribs 2213, and the multiple through grooves are symmetrically arranged relative to the center line L, so that the force-bearing areas on both sides of the center line L are evenly stressed, that is, the part of the vibration reduction device 100 connected to the suspension rod 3 is evenly stressed, further enhancing the fatigue resistance of the long-term deformation of the peripheral side of the through hole 220.

[0081] In some embodiments, the plurality of through grooves include a first through groove 2214 and a second through groove 2215, the distance between the first through groove 2214 and the center line L is greater than the distance between the second through groove 2215 and the center line L, and the length of the first through groove 2214 along the circumferential direction is greater than the length of the second through groove 2215 along the circumferential direction; the transition portion 223 is located on both sides of the center line L and is respectively provided with the first through groove 2214 and the second through groove 2215, wherein the portion of the peripheral structure 2212 corresponding to the first through groove 2214 is indirectly connected to the transition portion 223.

[0082] like Figure 8As shown, the main body 221 includes five reinforcing ribs 2213 spaced apart along the outer circumference, as well as two first through-slots 2214 and two second through-slots 2215. The distance between the first through-slot 2214 and the center line L refers to the distance between any point of the first through-slot 2214 and the center line L, and the distance between the second through-slot 2215 and the center line L refers to the distance between any point of the second through-slot 2215 and the center line L. The distance between the first through-slot 2214 and the center line L is greater than the distance between the second through-slot 2215 and the center line L, that is, the length of the first through-slot 2214 along the circumferential direction is greater than the length of the second through-slot 2215 along the circumferential direction.

[0083] like Figure 7 As shown, the transition portion 223, the peripheral structure 2212, the plurality of reinforcing ribs 2213, and the plurality of through-slots are symmetrically arranged relative to the center line L. A first through-slot 2214 and a second through-slot 2215 are respectively provided on either side of the center line L of the transition portion 223. The portion of the peripheral structure 2212 corresponding to the second through-slot 2215 is directly connected to the transition portion 223, while the portion of the peripheral structure 2212 corresponding to the first through-slot 2214 is indirectly connected to the transition portion 223. This further increases the deformability of the portion of the main body 221 located around the through hole 220, preventing the boom 3 from becoming stuck while moving within the through hole 220 and enhancing the fatigue resistance of the portion around the through hole 220 from long-term deformation.

[0084] In addition, grooves are provided on both sides of the transition portion 223 along its thickness direction, which can reduce the weight of the second moving part 2 and improve the structural strength and deformation resistance of the transition portion 223.

[0085] Figure 9 for Figure 7 Cross-section along direction CC.

[0086] In some embodiments, the main body 221 includes a first surface and a second surface opposite to each other along its own thickness direction, and the through hole 220 includes a first hole 220a and a second hole 220b arranged in sequence along the thickness direction of the main body 221. The first hole 220a is arranged to be axially tapered from the first surface to the second surface, and the second hole 220b is arranged to be axially tapered from the second surface to the first surface.

[0087] like Figure 9As shown, the through hole 220 includes a first hole 220a and a second hole 220b arranged in sequence along the thickness direction of the main body 221. The first hole 220a and the second hole 220b are both tapered holes, and the opening directions of the tapered holes are opposite, so that the suspension rod 3 can swing significantly in the through hole 220 without getting stuck. The aperture at the connection between the first hole 220a and the second hole 220b is the smallest, and the aperture can be larger than the diameter of the suspension rod 3. The through hole 220 and the suspension rod are in a clearance fit, so that the second connecting portion 22 can be slidably mounted on the suspension rod 3. In this way, when the cylinder assembly 300 vibrates in the vertical direction, the vibration reduction device 100 can be in a horizontal or approximately horizontal state through the sliding of the second connecting portion 22 on the suspension rod 3, so that the vibration reduction device 10 can generate a damping force in the horizontal direction, which is conducive to increasing the damping effect in the horizontal direction and preventing the lateral vibration displacement of the cylinder assembly 300 from being too large and hitting the box 200.

[0088] In some embodiments, the walls of the first hole 220a and the second hole 220b are each provided with an oil reservoir. The oil reservoir can be filled with lubricating oil or grease to reduce friction during the swinging of the boom, reduce wear on the through hole 220, and further extend the service life of the vibration reduction device.

[0089] In some embodiments, the through hole 220 is provided with an opening 220c along the circumferential direction, and the opening 220c is set at a preset angle between the midline along the circumferential direction and the center line L; the second connecting portion 22 also includes an anti-slip portion 222 connected to the main body portion 221, and the anti-slip portion 222 is arranged on the side of the main body portion 221 away from the second main body portion 21 and is connected to the opening 220c, and the anti-slip portion 222 forms a guide channel S connected to the through hole 220.

[0090] like Figure 7 and Figure 8 As shown, the suspension rod 3 passes through the through hole 220 of the main body 221 of the second connecting portion 22. The through hole 220 is provided with an opening 220c along the circumferential direction, which can increase the deformation at the through hole 220 and prevent the suspension rod 3 from getting stuck when moving in the through hole 220. In addition, the second connecting portion 22 also includes an anti-slip portion 222 connected to the main body 221. The anti-slip portion 222 is connected to the opening 220c to prevent the through hole 220 from being deformed too much when the cylinder assembly 300 vibrates too much, causing the suspension rod 3 to damage the through hole 220.

[0091] In some embodiments, the preset angle between the midline of the opening 220 c along the circumferential direction and the center line L is 0°.

[0092] like Figure 8As shown, the main body 221 is symmetrically arranged relative to the center line L, and the preset angle between the midline of the opening 220c along the circumferential direction and the center line L is 0°, that is, the opening 220c of the main body 221 is symmetrically arranged relative to the center line L, so that the circumferential side of the through hole 220 of the main body 221 can be evenly stressed and will not be deformed or even damaged due to stress concentration.

[0093] In some embodiments, the preset angle between the midline of the opening 220c along the circumferential direction and the center line L is greater than -45° and less than 45°. The main body 221 can be asymmetrically arranged relative to the center line L. In this case, the preset angle between the midline of the opening 220c along the circumferential direction and the center line L is greater than -45° and less than 45°. In this way, when the vibration of the barrel assembly 300 is too large, the suspension rod 3 can enter the anti-slip portion 222 from the through hole 220 through the opening 220c, thereby preventing the suspension rod 3 from damaging the through hole 220 due to excessive deformation of the through hole 220. The preset angle being greater than -45° and less than 45° also ensures that there is a sufficient area for deformation in the counterclockwise or clockwise circumferential direction from the opening 220c, and deformation or even damage will not occur due to stress concentration.

[0094] In some embodiments, the anti-slip portion 222 includes an extension portion 222a and a bending portion 222b that are spaced apart to form a guide channel S. The extension portion 222a is formed by one end of the opening 220c extending outward in a direction parallel to the center line L, and the bending portion 222b is formed by the other end of the opening 220c bending around the extension portion 222a. The guide channel S includes a first channel S1, a second channel S2, and a third channel S3 that are arranged in sequence and form a U-shaped structure. The first channel S1 is connected to the through hole 220, and the third channel S3 is gradually tapered in a direction away from the second channel S2.

[0095] like Figure 8As shown, the guide channel S formed between the extension portion 222a and the bent portion 222b of the anti-slip portion 222 is a labyrinthine channel. While ensuring that the main body 221 has sufficient deformation, it can also prevent the suspension rod 3 from falling off from the main body 221 of the second connecting portion 22. Among them, the first channel S1 of the guide channel S is connected to the through hole 220 and is parallel to the center line L, the second channel S2 is perpendicular to the center line L, and the third channel S3 is gradually tapered in the direction away from the second channel S2. The widths of the first channel S1 and the second channel S2 are both smaller than the diameter of the suspension rod 3, and the width of the end of the third channel S3 is smaller than the diameter of the suspension rod 3. In this way, when the hanger 3 tends to slide toward the guide channel S from the side of the opening 220c of the through hole 220, since the widths of the first channel S1 and the second channel S2 are both smaller than the diameter of the hanger 3, the hanger 3 is not easy to slide into the first channel S1 and the second channel S2; even if the main body 221 is subjected to a large force, resulting in a large deformation at the through hole 220, the hanger 3 slides into the first channel S1 and the second channel S2. Since the third channel S3 is gradually set in the direction away from the second channel S2, the end of the third channel S3 can also limit the hanger 3 from falling off from the guide channel S, thereby enhancing the fatigue resistance of the anti-slip part 222 to long-term deformation, and improving the connection reliability between the second moving part 2 and the hanger 3.

[0096] In some embodiments, the bending portion 222b includes a first rib 222c and a second rib 222d arranged on the outer peripheral side of the first rib 222c, and the first rib 222c is bent around the protruding portion 222a, and the thickness of the second rib 222d is less than the thickness of the first rib 222c.

[0097] like Figure 4 and Figure 8 As shown, the first rib 222c of the bent portion 222b is formed by bending around the protruding portion 222a, and the thickness of the second rib 222d is less than the thickness of the first rib 222c. The second rib 222d can make the overall thickness of the bent portion 222b thinner, which not only meets the structural strength requirements of the anti-slip portion 222, but also improves the deformation resistance of the anti-slip portion 222, and further enhances the fatigue resistance of the second connecting portion 22 to long-term deformation.

[0098] In some embodiments, the outer peripheral side of the second main body 21 is provided with a first limit platform 23 and a second limit platform 24 respectively connected to the two sides of the transition portion 223, the first limit platform 23 is located on one side of the center line L, and the second limit platform 24 is located on the other side of the center line L; the first moving part 1 also includes a first connecting part 12 connected to the first main body 11, and a third limit platform 13 extending along the circumferential direction is provided on the side of the first main body 11 facing away from the first connecting part 12, and a fourth limit platform 14 extending along the circumferential direction is provided on the side of the first main body 11 facing the first connecting part 12. When the second moving part 2 rotates by a first angle α in the first direction relative to the first moving part 1, the first limit platform 23 abuts against the third limit platform 13, and when the second moving part 2 rotates by a second angle β in the second direction relative to the first moving part 1, the second limit platform 24 abuts against the fourth limit platform 14. The first direction is opposite to the second direction, and the sum of the first angle α and the second angle β is less than 180°.

[0099] like Figure 6 and Figure 7 As shown, the first connection portion 12 of the first moving member 1 can be used to connect with the barrel assembly 300, and the second connection portion 22 of the second moving member 2 is sleeved on the outer peripheral side of the suspension rod 3 through the through hole 220, and the suspension rod 3 is used to connect with the box body 200. The outer peripheral side of the second main body 21 of the second moving member 2 is provided with a first limit platform 23 and a second limit platform 24, and the outer peripheral side of the first main body 11 of the first moving member 1 is provided with a third limit platform 13 and a fourth limit platform 14. Assuming that the first moving member 1 is stationary, when the second moving member 2 rotates by a first angle α in the counterclockwise direction relative to the first moving member 1 to the extreme position, the first limit platform 23 abuts against the third limit platform 13; when the second moving member 2 rotates by a second angle β in the clockwise direction relative to the first moving member 1 to the extreme position, the first limit platform 23 abuts against the fourth limit platform 14.

[0100] The first moving member 1 and the second moving member 2 are relatively rotatable within a preset angle, which is the sum of the first angle α and the second angle β. Optionally, the first angle α = 50° to 90°, and the second angle β = 40° to 90°. In one example, the first angle α = 80°, and the second angle β = 45°. The magnitudes of the first angle α and the second angle β are determined according to the spatial layout of the vibration reduction device 100. α + β < 180° prevents the first moving member 1 and the second moving member 2 from being unable to return to their initial positions during rotation due to excessive rotation angles, thereby losing the function of damping vibration again.

[0101] In some embodiments, a fifth limit platform 25 connected to the second limit platform 24 is further provided on the outer peripheral side of the second main body 21, and the outer diameter of the fifth limit platform 25 is smaller than the inner diameter of the fourth limit platform 14. A first anti-stuck angle θ1 is formed between the first limit platform 23 and the fifth limit platform 25 on one side of the transition portion 223, and a second anti-stuck angle θ2 is formed between the third limit platform 13 and the fourth limit platform 14 outside the rotation angle of the second moving part 2 relative to the first moving part 1. The first anti-stuck angle θ1 is greater than the second anti-stuck angle θ2.

[0102] like Figure 6 As shown, the first anti-stuck angle θ1 of the second moving part 2 is the angle formed between the first limiting platform 23 and the fifth limiting platform 25 on the side of the transition portion 223, and the second anti-stuck angle θ2 of the first moving part 1 is the angle formed between the third limiting platform 13 and the fourth limiting platform 14 in addition to the rotation angle of the second moving part 2 relative to the first moving part 1. θ1>θ2, so that the position of the first moving part 1 and the second moving part 2 after assembly can meet the spatial layout requirements and vibration reduction requirements of the clothing processing device 1000. For example, Figure 1 and Figure 6 In the embodiment, the second moving parts 2 of the four vibration damping devices 100 are all located on the right side of the first moving part 1 .

[0103] In some embodiments, the vibration reduction device 100 further includes a damping member 26 , which is disposed at the rotational connection between the first moving member 1 and the second moving member 2 , and is configured to provide a damping force when the first moving member 1 and the second moving member 2 rotate relative to each other.

[0104] When the clothing processing device 1000 is in the dehydration startup stage, the drum assembly 300 swings greatly under the action of eccentric centrifugal force to generate vibration. The damping member 26 is arranged at the rotation connection between the first moving member 1 and the second moving member 2, which can generate damping force when the first moving member 1 and the second moving member 2 rotate relative to each other to absorb and release part of the vibration energy, thereby reducing the lateral vibration displacement of the drum assembly 300.

[0105] In some embodiments, the damping member 26 is an annular structural member, and a notch 261 is provided along its own circumference. The second main body 21 has a accommodating cavity 210, and the side wall of the accommodating cavity 210 is provided with a stop rib 211. The damping member 26 is accommodated in the accommodating cavity 210, and the notch 261 is snap-connected with the stop rib 211; the first main body 11 is provided with a boss 111 that cooperates with the damping member 26, and the first main body 11 is pivotally connected to the second main body 21 through the boss 111.

[0106] like Figure 5 and Figure 6As shown, the first limit platform 23 of the second main body 21 is located on the outer peripheral side of the accommodating cavity 210, which can prevent the deformation of the accommodating cavity 210 from affecting the magnitude of the damping force and ensure the consistency of the damping. The material of the damping member 26 can be, for example, but not limited to, a viscoelastic damping material such as polyurethane. The viscoelastic damping material utilizes the hysteresis efficiency characteristics of the polymer to absorb vibration energy, partially converting the absorbed mechanical energy or sound energy into heat energy and dissipating it to reduce or lower the amplitude, thereby meeting the vibration resistance requirements. The notch 261 of the damping member 26 is snap-connected to the stop rib 211 provided on the side wall of the accommodating cavity 210, which can prevent the damping member 26 from rotating with the rotation of the second main body 21, thereby increasing the friction between the damping member 26 and the second main body 21. At the same time, the first main body 11 is provided with a boss 111 that cooperates with the damping member 26. A damping force is generated between the outer peripheral surface of the boss 111 and the inner wall of the damping member 26. The damping force is used to absorb and release vibration energy and reduce the lateral vibration displacement of the cylinder assembly 300.

[0107] In some embodiments, the retaining ribs 211 are symmetrically arranged relative to the center line L. When the main body 221 of the second connecting portion 22 is symmetrically arranged relative to the center line L, the portions of the main body 221 located on both sides of the center line L serve as force-bearing areas. The symmetrical arrangement of the retaining ribs 211 relative to the center line L allows the damping member 26 and the second connecting portion 22 to vibrate in the same direction, thereby preventing relative rotation between the damping member 26 and the retaining ribs 211, which could cause damage to the damping member 26 due to stress concentration, thereby further extending the service life of the vibration damping device 100.

[0108] Figure 10 for Figure 6 Schematic diagram of the cross-sectional structure along direction DD.

[0109] In some embodiments, the vibration reduction device 100 further includes a first fastening assembly 5, which is sequentially arranged along the axial direction through the second main body 21 and the first main body 11 to connect the first main body 11 to the second main body 21. Figure 10 As shown, the first fastening assembly 5 may include a rivet 5a and a washer 5b. The rivet 5a is sequentially passed through the washer 5b, the boss 111, and the first body 11 from one side of the second body 21 to axially connect the first body 11 and the second body 21. The first body 11 and the second body 21 are fixedly connected in the axial direction. The first body 11 and the second body 21 are mainly pivotally connected and rotate in the circumferential direction, so that the second moving member 2 and the first moving member 1 can rotate relative to each other within a preset angle to generate a damping force.

[0110] In some embodiments, the vibration damping device 100 further includes a second fastening assembly, a sleeve 121 and a pin sleeve 122. The sleeve 121 is provided in the first connecting portion 12, and the pin sleeve 122 is provided in the sleeve 121. The second fastening assembly sequentially penetrates the pin sleeve 122 and the mounting seat 301 of the cylinder assembly 300 in the axial direction to connect the first connecting portion 12 with the cylinder assembly 300. Figure 5 As shown, the second fastening assembly may include a pin that passes through the pin sleeve 122 and is connected to the top of the barrel assembly 300 .

[0111] It can be understood that the clothing processing device 1000 of the present application is not limited to a pulsator washing machine or a drum washing machine, but can also be a dryer, a combined dryer, etc. As long as the clothing processing device is equipped with a vibration reduction device 100, it is within the scope of protection of the present application and will not be described in detail.

[0112] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
