Description

Technical Field

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

[0002] Currently, the drum is an indispensable structure in clothing processing equipment such as dryers and washing machines. The front and rear ends of the drum are supported by support plates and other structures, and the drum is driven to rotate by a drive component. However, in order to ensure the rotation of the drum, an annular gap is formed between the support plate and the end of the drum, which reduces the sealing of the inside of the drum and affects the effect of clothing processing.

[0003] One type of dryer in the related technology includes a roller and a support plate. A felt ring is placed in the gap between the roller and the front support plate. The felt ring slides and rubs against the flanges at the front and rear ends of the roller, which allows the roller to rotate freely and also forms a seal inside the roller.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The sliding friction between the roller's flange and the felt ring increases the load on the drive motor, increasing its operating power and generating noise.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a roller and a garment handling device to reduce the coefficient of friction between the flange and the felt part of the roller, thereby reducing the resistance of sliding friction generated between the flange and the felt part, reducing the load on the drive motor of the garment handling device, and reducing noise.

[0009] In some embodiments, the roller includes a cylinder body and a lubricating coating. The two ends of the cylinder body in the axial direction are a first port and a second port, respectively, and an outwardly protruding flange is formed at the edge of both the first port and the second port; the lubricating coating is disposed on the flange of the first port and the second port; wherein, when the roller is used in a garment processing device, the lubricating coating is slidably connected to the felt portion of the garment processing device.

[0010] Optionally, the lubricating coating and the flange are integrated into one structure.

[0011] Optionally, the lubricating coating is fixed to the flange by sintering, forming an integral structure with the flange.

[0012] Alternatively, the lubricating coating is fixed to the flange by physical vapor deposition and sintering, forming an integral structure with the flange.

[0013] Optionally, the components of the lubricating coating include diamond, nano-ceramics, graphite, graphene, solid lubricants, and anti-wear agents.

[0014] Optionally, the roller further includes a rear plug. The rear plug is disposed within a second port on the axial direction of the roller body, sealing the second port.

[0015] Optionally, when the garment handling device is a washing machine, the rear end is a circular plate-shaped structure.

[0016] Optionally, when the clothing handling device is a dryer, the rear plug is a circular mesh structure with multiple flow holes.

[0017] Optionally, along the axial direction of the cylinder, the thickness of the lubricating coating is greater than or equal to 1 micrometer and less than or equal to 3 micrometers.

[0018] In some embodiments, the garment handling apparatus includes a roller according to any of the above embodiments.

[0019] The drum and clothing handling device provided in this disclosure can achieve the following technical effects:

[0020] By applying a lubricating coating to the flanges of the first and second ports along the axial direction of the drum, the lubricating coating contacts the felt portion when the drum is assembled in the garment handling device. As the drum rotates, the lubricating coating can slide relative to the felt portion, reducing the coefficient of friction between the flanges and the felt portion. This reduces the resistance of sliding friction between the flanges and the felt portion, lowers the load on the drive motor of the garment handling device, reduces the operating power of the drive motor, and reduces noise.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0037] Combination Figures 1-6 As shown, in some embodiments, the roller includes a cylinder 100 and a lubricating coating 200. The two axial ends of the cylinder 100 are a first port 110 and a second port 120, respectively, and both the first port 110 and the second port 120 have outwardly protruding flanges 300 formed at their edges. The lubricating coating 200 is disposed on the flanges 300 of the first port 110 and the second port 120. When the roller is used in a garment processing device, the lubricating coating 200 is slidably connected to the felt portion 500 in the garment processing device.

[0038] The roller provided in this embodiment of the present disclosure has a lubricating coating 200 provided on the flanges 300 of the first port 110 and the second port 120 along the axial direction of the roller body 100. When the roller is used in a garment handling device, the lubricating coating 200 contacts the felt portion 500. When the roller body 100 rotates, the lubricating coating 200 can slide relative to the felt portion 500, reducing the coefficient of friction between the flanges 300 and the felt portion 500 of the roller body 100. This reduces the resistance of sliding friction between the flanges 300 and the felt portion 500, reduces the load on the drive motor of the garment handling device, reduces the operating power of the drive motor, and reduces noise.

[0039] Optionally, the cylinder 100 has a cylindrical structure with a uniform diameter along its axial direction, and the first port 110 and the second port 120 of the cylinder 100 have the same area along their axial direction. By designing the cylinder 100 as a cylindrical structure with a uniform diameter along its axial direction, the overall force on the cylinder 100 is more evenly distributed during rotation, resulting in higher stability. Furthermore, the internal space of the cylinder 100 is more regular, allowing for more efficient placement of clothing.

[0040] Specifically, the flange 300 provided at the first port 110 is the first flange 310, and the flange 300 provided at the second port 120 is the second flange 320. Both the first flange 310 and the second flange 320 are provided with a lubricating coating 200. In this way, with the first flange 310 at the first port 110 and the second flange 320 at the second port 120, and with the lubricating coating 200 on both the first flange 310 and the second flange 320, when the roller is assembled and used, the lubricating coating 200 on the first flange 310 and the second flange 320 are slidably connected to the corresponding felt part 500. When the roller body 100 rotates, it can reduce the sliding friction resistance generated between the first flange 310 and the second flange 320 and the felt part 500, reduce the load on the drive motor, and reduce the noise generated by friction.

[0041] Understandably, the first flange 310 protruding outward along the edge of the first port 110 means that the first flange 310 protrudes upward along the axial direction of the cylinder 100 and away from the second port 120 along the edge of the first port 110; the second flange 320 protruding outward along the edge of the second port 120 means that the second flange 320 protrudes upward along the axial direction of the cylinder 100 and away from the first port 110 along the edge of the second port 120.

[0042] Optionally, the lubricating coating 200 on the first flange 310 is located at the outwardly protruding end of the first flange 310, and the lubricating coating 200 on the second flange 320 is located at the outwardly protruding end of the second flange 320. In this way, since the distance between the outwardly protruding end of the first flange 310 and its corresponding felt portion 500 is closest when the roller is assembled and used, and the distance between the outwardly protruding end of the second flange 320 and its corresponding felt portion 500 is also closest, and the resistance to sliding friction between the outwardly protruding ends of the first flange 310 and the second flange 320 and their corresponding felt portions 500 is also greatest when the roller rotates, placing the lubricating coating 200 on the outwardly protruding ends of the first flange 310 and the second flange 320 and their corresponding felt portions 500 further reduces the frictional resistance.

[0043] Optionally, the lubricating coating 200 provided on the first flange 310 and the second flange 320 is annular in shape. Since both the first flange 310 and the second flange 320 are annular structures, and the outwardly protruding ends of both flanges are also annular, the lubricating coating 200 provided on the first flange 310 and the second flange 320 is annular in shape, thus matching the shapes of the first flange 310 and the second flange 320.

[0044] Optionally, the lubricating coating 200 and the flange 300 are an integral structure. In this way, the lubricating coating 200 and the flange 300 form a whole, and the connection strength between the lubricating coating 200 and the flange 300 is higher. Under the high-speed rotation of the cylinder 100, the lubricating coating 200 is not easy to fall off, thus extending the service life of the roller.

[0045] Specifically, the first flange 310 and its corresponding lubricating coating 200 are an integral structure, and the second flange 320 and its corresponding lubricating coating 200 are an integral structure.

[0046] Optionally, the thickness of the lubricating coating 200 along the axial direction of the cylinder 100 is greater than or equal to 1 micrometer and less than or equal to 3 micrometers. When the thickness of the lubricating coating 200 along the axial direction of the cylinder 100 is less than 1 micrometer, the thickness of the lubricating coating 200 is relatively thin. During drum assembly, the distance between the lubricating coating 200 and the corresponding felt portion 500 is relatively large, which affects the seal between the flange 300 and the felt portion 500, thus affecting the sealing effect of the cylinder 100. When the thickness of the lubricating coating 200 along the axial direction of the cylinder 100 is greater than 3 micrometers, the thickness of the lubricating coating 200 is relatively thick. During drum assembly, the distance between the lubricating coating 200 and the corresponding felt portion 500 is relatively small. During drum rotation, the sliding friction resistance between the lubricating coating 200 and the felt portion 500 is large, resulting in a larger load on the drive motor and greater noise generated by friction. Therefore, the thickness of the lubricating coating 200 along the axial direction of the cylinder 100 is set to be greater than or equal to 1 micrometer and less than or equal to 3 micrometers. This ensures that the thickness of the lubricating coating 200 can form a good seal with the felt part 500 when the drum is assembled and used, while also avoiding the increase in frictional resistance due to the excessive thickness of the lubricating coating 200. This results in a good seal inside the cylinder 100 while reducing the frictional resistance between the lubricating coating 200 and the felt part 500, thus reducing the load on the drive motor.

[0047] Optionally, the thickness of the lubricating coating 200 along the axial direction of the cylinder 100 is equal to 2 micrometers. Setting the thickness of the lubricating coating 200 to 2 micrometers ensures a good seal between the lubricating coating 200 and the felt portion 500 during drum assembly and use, while also preventing excessively thick lubricating coating 200 from increasing frictional resistance. This results in a better seal inside the cylinder 100 while reducing the frictional resistance between the lubricating coating 200 and the felt portion 500, thus lowering the load on the drive motor.

[0048] In one embodiment, the lubricating coating 200 is fixed to the flange 300 by sintering, forming an integral structure with the flange 300. This high-temperature sintering process fixes the lubricating coating 200 to the flange 300, creating an integral structure, resulting in a more secure adhesion of the lubricating coating 200 to the flange 300 and further improving the connection strength between the lubricating coating 200 and the flange 300.

[0049] For example, high-temperature sintering refers to transforming powdered materials into a dense body. After the powder is shaped, the dense body obtained through sintering is a polycrystalline material. At high temperatures (not exceeding the melting point), the solid particles of the ceramic green body bond together, the grains grow, and the voids (pores) and grain boundaries gradually decrease. Through the transfer of matter, its total volume shrinks, its density increases, and finally it becomes a dense polycrystalline sintered body with a certain microstructure. By fixing the lubricating coating 200 onto the flange 300 through high-temperature sintering, the overall density of the lubricating coating 200 is higher, and the wear resistance and lubrication effect are better.

[0050] Specifically, the lubricating coating 200 on the first flange 310 and the second flange 320 is fixed by sintering.

[0051] Optionally, the sintering temperature of the lubricating coating 200 is greater than or equal to 180℃ and less than or equal to 220℃. When the sintering temperature of the lubricating coating 200 is less than 180℃, the sintering temperature is relatively low, resulting in poor sintering and potentially causing the lubricating coating 200 to detach. When the sintering temperature of the lubricating coating 200 is greater than 220℃, the sintering temperature is relatively high, which may lead to over-sintering of the lubricating coating 200, affecting its adhesion stability. Therefore, a sintering temperature of 180℃ or greater and less than or equal to 220℃ ensures a moderate sintering temperature, allowing the lubricating coating 200 to adhere more stably to the flange 300, thus improving its stability.

[0052] Optionally, the sintering temperature of the lubricating coating 200 is 200℃. In this way, controlling the sintering temperature at 200℃ can ensure the sintering and fixing effect of the lubricating coating 200, and the lubricating coating 200 is more stably attached to the flange 300.

[0053] Understandably, when the lubricating coating 200 on the first flange 310 and the second flange 320 is fixed by sintering, the sintering temperature is 200℃.

[0054] In another embodiment, the lubricating coating 200 is fixed to the flange 300 by physical vapor deposition and sintering, forming an integral structure with the flange 300. Physical vapor deposition (PVD) is a technique that uses physical methods under vacuum conditions to vaporize the surface of a material source into gaseous atoms or molecules, or partially ionize them into ions, and then deposits a thin film with specific functions on the substrate surface through a low-pressure gas process. PVD technology has a simple process, is environmentally friendly, pollution-free, requires less material, produces a uniform and dense film, and has strong adhesion to the substrate. The lubricating coating 200 formed on the flange 300 by PVD has higher overall uniformity. Then, sintering further adheres and fixes the lubricating coating 200 to the flange 300, improving the adhesion strength of the lubricating coating 200 and making it more wear-resistant.

[0055] For example, in the fixing stage of the lubricating coating 200, the material is first vaporized: that is, the material evaporates, sublimates, or is sputtered, i.e., through a material vaporization source; then, the migration of material atoms, molecules, or ions, supplied by the vaporization source, results in various reactions after collisions; then, the material atoms, molecules, or ions are deposited on the flange 300 to form a film. The lubricating coating 200 after film formation is fixed on the flange 300 by sintering.

[0056] Specifically, the lubricating coating 200 on the first flange 310 and the second flange 320 is fixed by physical vapor deposition and sintering.

[0057] In one embodiment, the lubricating coating 200 comprises diamond, nano-ceramics, graphite, graphene, solid lubricant, and anti-wear agent. Thus, the lubricating coating 200 formed using these materials exhibits better adhesion and superior wear resistance and lubrication.

[0058] For example, diamond, nano-ceramics, graphite, graphene, solid lubricant and anti-wear agent are attached to the flange 300 by physical vapor deposition to form a lubricating coating 200, and then the lubricating coating 200 is fixed by high-temperature sintering.

[0059] It is understandable that the lubricating coating 200 includes, but is not limited to, materials such as diamond, nano-ceramics, graphite, graphene, solid lubricants and anti-wear agents, which will not be elaborated here.

[0060] Combination Figure 4 and Figure 5As shown, in some embodiments, the roller further includes a rear plug 400. The rear plug 400 is disposed within the second port 120 in the axial direction of the roller body 100, sealing the second port 120. Thus, since the roller body 100 only needs to retain one opening for loading and unloading clothes, the rear plug 400 is provided to seal the second port 120.

[0061] Understandably, the first port 110 is the front port of the cylinder 100, and the second port 120 is the rear port of the cylinder 100.

[0062] Combination Figure 4 As shown, in one embodiment, when the clothing handling device is a washing machine, the rear plug 400 is a circular plate-shaped structure.

[0063] In this embodiment of the present disclosure, when the drum is a washing machine drum, the front port of the drum body 100 is usually sealed with a front cover, that is, the first port 110 is sealed by the front cover of the washing machine, while the rear port of the drum body 100 needs to be sealed with a circular plate-shaped rear plug 400, that is, the second port 120 of the drum body 100 needs to be sealed with a circular plate-shaped rear plug 400, so as to ensure the sealing effect inside the drum body 100.

[0064] Specifically, the rear plug 400 is a solid circular plate structure that completely seals the second port 120.

[0065] Combination Figure 5 As shown, in another embodiment, when the clothing handling device is a dryer, the rear plug 400 is a circular mesh structure, and the rear plug 400 is provided with a plurality of flow holes 410.

[0066] In this embodiment, when the drum is a dryer drum, the rear port of the drum 100 needs to allow for the flow of drying air. Therefore, to ensure that the second port 120 of the drum 100 can smoothly allow for the flow of drying air while preventing clothes from coming out of the second port 120, the rear plug 400 is configured as a circular mesh structure with multiple flow holes 410. This allows the rear plug 400 to both seal the second port 120, preventing clothes from coming out of the drum 100, and ensure that the drying airflow can flow smoothly from the second port 120.

[0067] Optionally, multiple flow holes 410 are evenly distributed on the side wall of the rear plug 400. This allows the drying airflow to flow evenly from the second port 120, improving the airflow uniformity inside the cylinder 100 and ensuring the drying effect.

[0068] Combination Figure 1 and Figure 6As shown, in some embodiments, the garment handling apparatus includes: a roller according to any of the above embodiments.

[0069] The garment handling apparatus provided in this embodiment of the present disclosure provides a lubricating coating 200 on the flanges 300 of the first port 110 and the second port 120 along the axial direction of the drum 100. When the drum is assembled and used in the garment handling apparatus, the lubricating coating 200 contacts the felt portion 500. As the drum 100 rotates, the lubricating coating 200 can slide relative to the felt portion 500, reducing the coefficient of friction between the flanges 300 and the felt portion 500. This reduces the resistance of sliding friction between the flanges 300 and the felt portion 500, lowers the load on the drive motor of the garment handling apparatus, reduces the operating power of the drive motor, and reduces noise.

[0070] Alternatively, the garment handling device may include a dryer or a washing machine.

[0071] Understandably, the garment handling device has a drive motor to drive the roller to rotate. The garment handling device and the roller's flange 300 are provided with felt parts 500, which are felt rings.

[0072] The foregoing description and accompanying drawings fully illustrate embodiments of the present disclosure to enable those skilled in the art to practice them.

Individual components and functions are optional unless explicitly required, and the order of operation may vary. Parts and features of some embodiments may be included or substituted for parts and features of other embodiments.
