[0038] As Figures 1 to 8As shown, according to the embodiment of the present application, a cylinder device 10 is provided, which comprises a cylinder 100 and a noise reduction structure 300, the outer peripheral wall 101 of the cylinder 100 has a first area 102 for mounting a damping assembly 200, and the noise reduction structure 300 is arranged on the first area 102.

[0039] The noise reduction structure 300 can be a porous sound-absorbing noise reduction member, sound-absorbing cotton, a reflective noise reduction member, etc. The noise reduction structure 300 can be mounted on the outer peripheral wall 101 (the first area 102) of the cylinder 100. The noise reduction structure 300 can be a separately processed component mounted on the cylinder 100, or the noise reduction structure 300 can be a structure integrally formed with the cylinder 100.

[0040] The cylinder 100 can be a plastic cylinder 100, and the outer peripheral wall 101 of the cylinder 100 refers to the circumferential side of the cylinder 100 facing outward.

[0041] The first area 102 of the cylinder 100 can be provided with a mounting structure 400, which is a structure of the cylinder 100 for mounting the damping assembly 200. The noise reduction structure 300 can also be connected with the mounting structure 400. The damping assembly 200 can play a buffering and damping role in the case of vibration and shaking of the cylinder device 10, so as to protect the cylinder 100.

[0042] The first area 102 refers to a local position of the outer peripheral wall 101 of the cylinder 100, which is an area of the outer peripheral wall 101 for assembling the damping assembly 200, including an area where the damping assembly 200 is located and a nearby area surrounding the damping assembly 200. Specifically, the first area 102 can be roughly understood as an area where the mounting structure 400 is arranged on the outer peripheral wall 101. Figure 2 The area surrounded by the middle black dashed line can be considered as the first area 102.

[0043] The cylinder device 10 can be provided with one or more damping assemblies 200. In the case of providing a plurality of damping assemblies 200, the plurality of damping assemblies 200 can be dispersedly arranged, and the area where each damping assembly 200 is located can be considered as a respective first area 102. In the case that adjacent damping assemblies 200 are arranged relatively close to each other, the first area 102 can be formed by the area where the adjacent damping assemblies 200 are located together.

[0044] For example, as shown in FIG. 1, the plurality of damping assemblies 200 can be dispersedly arranged along the circumference of the cylinder 100. Figures 1 to 4 For example, as shown in FIG. 1, the plurality of damping assemblies 200 can be dispersedly arranged along the circumference of the cylinder 100.

[0045] Corresponding to one damping assembly 200, the noise reduction structure 300 can be provided one or more, in the case of multiple noise reduction structure 300 is provided, multiple noise reduction structure 300 can be scattered. Noise reduction structure 300 can be provided on one side of the damping assembly 200, also can be provided on the other side of the damping assembly 200 also has noise reduction structure 300.

[0046] Exemplary, in the first region 102, the damping assembly 200 is provided with one or more noise reduction structure 300 along the circumferential side of the cylinder 100, or, the damping assembly 200 is provided with one or more noise reduction structure 300 along the circumferential side of the cylinder 100 respectively.

[0047] Exemplary, in the first region 102, the damping assembly 200 is provided with one or more noise reduction structure 300 along the axial side of the cylinder 100, or, the damping assembly 200 is provided with one or more noise reduction structure 300 along the axial side of the cylinder 100 respectively.

[0048] According to the cylinder device 10 of the embodiment, by setting the first region 102 of the damping assembly 200 on the cylinder 100, and setting the noise reduction structure 300, the noise generated in the process of mutual cooperation between the damping assembly 200 and the cylinder 100 can be reduced, thereby reducing the operation noise of the equipment applying the cylinder device 10 of the embodiment, improving the operation noise environment of the equipment, and improving the user experience.

[0049] The cylinder device 10 of the embodiment can be applied to a clothes treatment equipment (such as a washing machine), and serves as an outer cylinder of the clothes treatment equipment. The clothes treatment equipment can further include an inner cylinder and a box body. The inner cylinder is sleeved in the cylinder 100 of the cylinder device 10 and is arranged to rotate around its own axis relative to the cylinder 100 under the driving action of a driving device. The cylinder device 10 is arranged in the box body, and the damping assembly 200 is located between the inner wall of the box body and the outer peripheral wall 101 of the cylinder 100. The damping assembly 200 can be arranged to connect one end with the outer peripheral wall 101 of the cylinder 100 and the other end with the box body. The damping assembly 200 plays a role of buffering and balancing the drum in the clothes treatment equipment, and reduces the vibration of the cylinder 100. The damping assembly 200 can be arranged as a damping shock absorber. During the operation of the clothes treatment equipment, they absorb and disperse the vibration through friction, thereby reducing the noise and vibration. However, when the cylinder 100 moves in a shaking or vibration manner, the damping assembly 200 causes the cylinder 100 to locally deform (micro-deformation) and vibrate, which also generates a certain noise.

[0050] After the cylinder device 10 of the embodiment is applied to the clothes treatment equipment, the noise reduction structure 300 can reduce the noise generated by the impact of the damping assembly 200 on the cylinder 100, improve the operation noise environment of the clothes treatment equipment, and improve the user experience.

[0051] According to some embodiments of the present application, optionally, as shown in Figures 5 to 8 The noise reduction structure 300 includes a noise reduction plate 310 having opposite first and second ends 311 and 312, the first end 311 having a greater thickness than the second end 312.

[0052] The thickness w of the noise reduction plate 310 can be gradually reduced from the first end 311 to the second end 312. The thickness w of the noise reduction plate 310 can also be gradually reduced gradually. Along the thickness direction, the two opposite surfaces of the noise reduction plate 310 are defined as the first and second side surfaces 313 and 314, respectively. Along the first end 311 to the second end 312, the noise reduction plate 310 can be inwardly contracted toward the second side surface 314 from the first side surface 313, so that the thickness w of the noise reduction plate 310 is reduced. The noise reduction plate 310 can also be inwardly contracted toward the first side surface 313 from the second side surface 314, so that the thickness w of the noise reduction plate 310 is reduced. The noise reduction plate 310 can also be inwardly contracted toward the first side surface 313 from the second side surface 314, and the second side surface 314 is also inwardly contracted toward the first side surface 313, so that the thickness w of the noise reduction plate 310 is reduced.

[0053] The surface of the noise reduction plate 310 can intersect the outer peripheral wall 101, for example, can be substantially perpendicular to the outer peripheral wall 101 (the first region 102), the first and second ends 311 and 312 of the noise reduction plate 310 can be two ends of the noise reduction plate 310 oppositely arranged along the radial direction of the cylinder body 100. Specifically, the first end 311 can be an end of the noise reduction plate 310 connected with the outer peripheral wall 101 (the first region 102) (the inner end of the noise reduction plate 310), the second end 312 can be an end of the noise reduction plate 310 away from the outer peripheral wall 101 (the outer end of the noise reduction plate 310), the thickness of the inner end (the first end 311) of the noise reduction plate 310 is greater than the thickness of the outer end (the second end 312) of the noise reduction plate 310.

[0054] In some other embodiments, the first end 311 and the second end 312 of the noise reduction plate 310 can also be two ends of the noise reduction plate 310 along a direction perpendicular to the radial direction of the cylinder body 100. For example, the plate surface of the noise reduction plate 310 can be arranged substantially perpendicular to the outer peripheral wall 101 (the first region 102), the width direction of the noise reduction plate 310 is arranged substantially along the radial direction of the cylinder body 100, the length direction of the noise reduction plate 310 is arranged substantially along the circumferential direction of the cylinder body 100, and the opposite ends of the noise reduction plate 310 along the circumferential direction can be the first end 311 and the second end 312, and the thickness w of the noise reduction plate 310 can gradually decrease along the circumferential direction of the cylinder body 100. For another example, the plate surface of the noise reduction plate 310 can be arranged substantially perpendicular to the outer peripheral wall 101 (the first region 102), the width direction of the noise reduction plate 310 is arranged substantially along the radial direction of the cylinder body 100, the length direction of the noise reduction plate 310 is arranged substantially along the axial direction of the cylinder body 100, and the opposite ends of the noise reduction plate 310 along the axial direction can be the first end 311 and the second end 312, and the thickness w of the noise reduction plate 310 can gradually decrease along the axial direction of the cylinder body 100.

[0055] In the noise generated during the cooperation of the shock absorbing assembly 200 and the cylinder body 100, part of the noise can propagate in the form of bending waves. Since the wave speed of the bending wave decreases with the decrease of the thickness, the wavelength decreases, the vibration amplitude of the wave increases, and the wave is gathered to the area with small thickness. In this embodiment, the noise reduction plate 310 is arranged in a structure with thick one end and thin the other end. The end with small thickness w of the noise reduction plate 310 is more fragile and easy to change, and the bending wave is more likely to generate an acoustic black hole when propagating on the noise reduction plate 310, thereby reducing the structure vibration and reducing the noise.

[0056] According to some embodiments of the present application, optionally, the thickness w of the noise reduction plate 310 gradually decreases from the first end 311 to the second end 312.

[0057] The thickness w of the noise reduction plate 310 gradually decreases, and the noise reduction plate 310 forms a wedge-shaped structure, so that when the noise (bending wave) propagates in the noise reduction plate 310, the wave speed gradually decreases with the decrease of the thickness, which is beneficial to improve the uniformity of the change of the noise transmission in the noise reduction plate 310, and further improve the noise reduction effect.

[0058] According to some embodiments of the present application, optionally, the noise reduction plate 310 has a first side surface 313 and a second side surface 314 arranged oppositely along the thickness direction, and the first side surface 313 and the second side surface 314 gradually decrease and approach each other from the first end 311 to the second end 312, so that the thickness of the noise reduction plate 310 decreases.

[0059] Optionally, the first side surface 313 and the second side surface 314 are arranged in mirror symmetry with respect to the middle line E of the noise reduction plate 310, and the middle line E is the middle line of the noise reduction plate 310 along the thickness direction, which is perpendicular to the arrangement direction of the first end 311 to the second end.

[0060] The symmetry between the first side 313 and the second side 314 is not strictly required, and the change rates of the two sides are substantially the same, and the symmetry is considered to be achieved within the processing error.

[0061] The thickness w of the noise reduction plate 310 gradually decreases through the inward shrinkage of the two sides, and the noise reduction plate 310 can form a wedge structure. When the noise (bending wave) propagates in the noise reduction plate 310, the wave speed gradually decreases with the decrease of the thickness, which is beneficial to improve the uniformity of the change of the noise in the noise reduction plate 310, and the end with smaller thickness of the noise reduction plate 310 is more likely to deform, thereby improving the noise reduction effect.

[0062] Optionally, the first side 313 and the second side 314 can gradually decrease in slope, or can gradually decrease in curved surface.

[0063] According to some embodiments of the present application, as shown in Figure 8 the first side 313 and the second side 314 respectively extend along a power function curve from the first end 311 to the second end 312.

[0064] The first side 313 and the second side 314 can extend along the same power function curve, so that the noise reduction plate 310 gradually decreases from the first end 311 to the second end 312.

[0065] The first side 313 and the second side 314 respectively extend along a power function curve, which can be understood as, as shown in Figure 5 and Figure 8 the edge profile of the cross section (parallel to the thickness direction and parallel to the arrangement direction of the first end 311 to the second end 312) of the noise reduction plate 310 extends along a power function curve, wherein the two profile lines on both sides of the thickness direction can be curves of the same power function, at this time, the first side 313 and the second side 314 are substantially mirror-symmetrically arranged; the two profile lines on both sides of the thickness direction can be curves of different power functions.

[0066] The power function can be a quadratic power function, a cubic power function, or a higher power function.

[0067] In one embodiment, as shown in Figure 8 the first side 313 and the second side 314 are mirror-symmetrically arranged, and the power function curve of the first side 313 and the second side 314 of the noise reduction plate 310 can be substantially a negative power function curve with the thickness center (reference center line E) of the first end 311 as the origin O, the thickness direction as the X direction, and the direction from the first end 311 to the second end 312 as the Y direction, wherein y(x) = a*x -m, x is the distance of the current point relative to the origin O along the X direction, y(x) is the distance of the current point (the point with a distance x relative to the origin O along the X direction) from the first end 311 (i.e., the origin O) along the Y direction, a is a non-zero constant, -m is an index, i.e., negative m, m itself takes a positive integer, and m is greater than or equal to 2.

[0068] It should be noted that, Figure 8 The dashed line is only a schematic annotation for easy understanding, and there is no dashed line part in the actual structure.

[0069] The thickness w of the noise reduction plate 310 is generally as thin as possible. Considering the structural strength and noise reduction effect, the thickness of the first end 311 of the noise reduction plate 310 can be 0.6 mm to 1.2 mm, and specifically, the thickness of the first end 311 of the noise reduction plate 310 can be 0.6 mm, 0.8 mm, 1 mm, 1.2 mm, etc. Optionally, the thickness of the second end 312 of the noise reduction plate 310 can be 1 mm to 3 mm, and specifically, it can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc.

[0070] The size of the noise reduction plate 310 from the first end 311 to the second end 312 is generally limited by the installation space between the cylinder body 100 and the box body, and the size of the noise reduction plate 310 should interfere with the box body as much as possible. Optionally, the size of the noise reduction plate 310 from the first end 311 to the second end 312 can be 10 mm to 25 mm, and specifically, it can be about 10 mm, 11 mm, 15 mm, 17 mm, 18 mm, 20 mm, etc.

[0071] Low-frequency noise is relatively difficult to reduce in actual application because of its long wavelength and strong obstacle ability. The vibration noise generated by the shock absorbing assembly 200 impacting the cylinder body 100 includes a lot of low-frequency noise. The noise reduction plate 310 in this embodiment is provided in a thin plate wedge structure. In the thin plate wedge structure, if the thickness of the structure decreases in a power function form, the wave speed of the bending wave will gradually decrease with the decrease of the thickness, resulting in a decrease in the wavelength, an increase in the vibration amplitude of the wave, and an aggregation to the area with smaller thickness. When reaching the cutoff (the tip of the structure, i.e., the first end 311), the acoustic black hole is more likely to be generated due to the weak structure and easy deformation, so as to eliminate part of the vibration energy, reduce the structure vibration, and better reduce the low-frequency noise.

[0072] In some embodiments, the noise reduction structure 300 is arranged as close as possible to the maximum point of the vibration of the cylinder body 100 caused by the shock absorbing assembly 200, so that the noise reduction structure 300 can be arranged as close as possible to the setting position of the shock absorbing assembly 200.

[0073] According to some embodiments of the present application, the first end 311 is fixedly connected with the outer peripheral wall 101, and the second end 312 is arranged away from the outer peripheral wall 101 compared with the first end 311.

[0074] That is, the thicker first end 311 is the end of the noise reduction plate 310 connected with the outer peripheral wall 101, and the first end 311 forms the root of the noise reduction plate 310, and the thinner second end 312 is the end of the noise reduction plate 310 away from the outer peripheral wall 101, and the second end 312 forms the tip of the noise reduction plate 310.

[0075] The thicker end of the noise reduction plate 310 is connected with the outer peripheral wall 101, and the thinner end is set as a free tip, and the cross-sectional direction (from thick to thin) of the noise reduction structure 300 is basically consistent with the transmission direction of the bending wave (noise), so that the vibration of the cylinder 100 can be better transmitted to the noise reduction plate 310, and the vibration is propagated from the thick end to the thin end of the noise reduction plate 310, so that it is easier to produce an acoustic black hole, and part of the vibration energy can be eliminated, the structure vibration is reduced, and a better noise reduction (especially low frequency noise) effect is achieved.

[0076] The noise reduction plate 310 can be vertically arranged relative to the outer peripheral wall 101, that is, from the first end 311 to the second end 312, the noise reduction plate 310 extends outward along the radial direction of the cylinder 100. The outer peripheral wall 101 is also arranged vertically relative to the outer peripheral wall 101, that is, the line connecting the first end 311 to the second end 312 is arranged obliquely relative to the side of the axial direction or the side of the circumferential direction of the radial direction of the cylinder 100.

[0077] According to some embodiments of the present application, optionally, as shown in Figures 1 to 7 The first area 102 is provided with a mounting structure 400, and the damping assembly 200 is mounted on the mounting structure 400, and the noise reduction structure 300 is connected with the mounting structure 400.

[0078] Optionally, the noise reduction structure 300 can be mounted on the mounting structure 400, for example, the first end 311 of the noise reduction structure 300 is fixedly connected with the mounting structure 400.

[0079] Optionally, the noise reduction structure 300 can be fixedly connected with the outer peripheral wall 101 (the first area 102) of the cylinder 100 and connected with the mounting structure 400. For example, the first end 311 of the noise reduction plate 310 is connected with the outer peripheral wall, and the side of the noise reduction plate 310 connected between the first end 311 and the second end 312 is connected with the mounting structure 400.
