[0002] In front-loading washing machines, a support frame is usually installed on one side of the drum to distribute the weight of the drum and improve its stability during rotation.

[0003] However, during the operation of the washing machine, the clothes in the drum will exert force on the support frame. In order to improve the service life of the support frame itself, the relevant technology usually sets the support frame as an "I" shaped structure, but its cost is high. Utility Model Content

[0004] The main objective of this application is to provide a tube assembly and a garment processing device, which can reduce the manufacturing cost of the support frame and enhance the structural strength of the support arm itself, thereby extending the service life of the support frame.

[0005] On one hand, this application provides a tubular assembly for use in a garment processing device. The tubular assembly provided by this application includes a tubular body and a support frame. The tubular body has an inner cavity with a first cavity opening and a second cavity opening disposed opposite to each other. The first cavity opening is disposed facing the outside of the garment processing device. The support frame is disposed at the second cavity opening and has a first surface facing the first cavity opening. The first surface is provided with a recess and a reinforcing structure, and the reinforcing structure is disposed in the recess.

[0006] In some implementation schemes, the reinforcing structure includes reinforcing ribs.

[0007] In some embodiments, the support frame includes a connecting part and at least three support arms. The connecting part has a connecting hole for rotatably engaging with a connecting shaft. The at least three support arms are connected to the periphery of the connecting part and are evenly spaced apart. The end of the connecting part facing the first cavity and the ends of the at least three support arms facing the first cavity together form a first surface. Each support arm has a recess, and each recess has at least one reinforcing rib.

[0008] In some implementations, edge portions are formed on opposite sides of the recess in the width direction of the support arm; the dimension of the edge portions in the width direction of the support arm is greater than or equal to 3 mm.

[0009] In some embodiments, each recess is provided with a first reinforcing rib, which extends along the extension direction of the support arm; the first reinforcing rib has two sidewalls spaced apart along the width direction of the support arm, and the two adjacent sidewalls of two adjacent first reinforcing ribs in two adjacent recesses are connected by an arc-shaped wall.

[0010] In some embodiments, each recess further has a second reinforcing rib located on opposite sides of the first reinforcing rib, the second reinforcing rib extending along the extension direction of the support arm, the second reinforcing ribs located on opposite sides of the first reinforcing rib being arranged in axial symmetry with respect to the first reinforcing rib; two adjacent second reinforcing ribs in two adjacent recesses are connected by an arc-shaped connecting rib.

[0011] In some embodiments, the support arm extends along the radial direction of the connecting hole; the extension direction of the recess and the extension direction of the reinforcing rib are consistent with the extension direction of the support arm where the recess and the reinforcing rib are located.

[0012] In some embodiments, in the recessing direction of the recess, the size of the reinforcing rib is less than or equal to the recessing depth of the recess.

[0013] In some embodiments, the two ends of the support arm are a connecting end and a supporting end, respectively, the connecting end and the connecting part are connected, and the supporting end and the cylinder are connected; wherein, in the axial direction of the connecting part, the connecting end is arranged closer to the first cavity than the supporting end.

[0014] In another aspect, the present application provides a clothes processing device, comprising a driving mechanism and the above-mentioned cylinder assembly; the driving mechanism comprises a connecting shaft, the connecting shaft being rotationally connected with the support frame, and the driving structure being used to drive the support frame and the cylinder to rotate synchronously.

[0015] In the cylinder assembly and the clothes processing device in the embodiments of the present application, the support frame has a first face facing the first cavity, and the first face is provided with a recess and a reinforcing structure, the reinforcing structure being arranged in the recess.

[0016] Thus, during the working process of the clothes processing device, the clothes inside the cylinder assembly gather together and deviate from the center of the cylinder assembly during rotation, at this time, due to the arrangement of the reinforcing structure, the reinforcing structure can bear the force generated by a part of the clothes on the support frame, so that the support strength of the support frame can be ensured, thereby the service life of the support frame can be prolonged, and further the service life of the cylinder assembly and the clothes processing device provided in the embodiments of the present application can be prolonged.

[0017] In addition, by arranging the recess on the first face, the overall mass of the support frame can be reduced, and the amount of raw materials of the support frame can be reduced, so that the manufacturing cost of the support frame can be reduced. BRIEF DESCRIPTION OF DRAWINGS

[0040] In related technologies, the support frame includes a connecting part and three support arms. The connecting part is used to cooperate with the drive mechanism that drives the cylinder to rotate so as to drive the cylinder to rotate. The three support arms are connected to the outer periphery of the connecting part and are arranged at intervals. Specifically, the ends of the support arms are connected to the cylinder wall of the cylinder.

[0041] However, during the operation of the washing machine, the clothes in the drum will exert force on the support frame. In order to improve the service life of the support frame itself, related technologies usually set the support frame as an "I" shaped structure, which is more expensive.

[0042] Therefore, this application provides a tube assembly and a garment processing device. By providing a recess and a reinforcing structure on the first surface of the support frame, the strength of the support frame can be improved while keeping the manufacturing cost of the support frame low, thereby extending the service life of the support frame and thus extending the service life of the garment processing device.

[0043] It should be noted that the clothing processing device provided in this embodiment includes, but is not limited to, a washing machine. Here, the specific type of clothing processing device provided in this embodiment is not limited.

[0044] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.

[0045] like Figures 1 to 4 As shown, Figure 1 This is a three-dimensional structural diagram of the cylindrical assembly provided in the embodiments of this application. Figure 2 This is a three-dimensional structural diagram of the support frame in the cylindrical assembly provided in the embodiments of this application, viewed from a first perspective. Figure 3 This is a three-dimensional structural diagram of a support frame in a cylindrical assembly provided in an embodiment of this application, viewed from a second perspective. Figure 4 This is a three-dimensional structural diagram of another support frame in the tube assembly provided in this application embodiment, viewed from a third perspective. As shown in the figure, this embodiment provides a tube assembly 10, including a tube 1 and a support frame 2. The tube 1 has an inner cavity 11, and the inner cavity 11 has a first cavity opening 111 and a second cavity opening 112 disposed opposite to each other. The first cavity opening 111 is positioned facing outwards from the garment handling device; the support frame 2 is disposed at the second cavity opening 112. The support frame 2 is mainly provided to support the tube 1, improve the stability of the tube 1 during operation of the garment handling device, and reduce the noise generated during the rotation of the tube 1.

[0046] It should be noted that in some specific embodiments, both the cylinder 1 and the support frame 2 are made of metal. For example, the cylinder 1 can be made of stainless steel. No specific limitations are placed on the materials of the cylinder 1 and the support frame 2.

[0047] Furthermore, the support frame 2 has a first surface 21 and a second surface 22 arranged opposite to each other, wherein the first surface 21 is arranged facing the first cavity 111, and the second surface 22 is arranged away from the first cavity 111.

[0048] As can be seen from the above, during the operation of the clothing processing device, the force exerted by the clothing on the support frame 2 is mainly concentrated on the first surface 21. Moreover, in order to improve the service life of the support frame itself, the related technology usually sets the support frame as an "I" shaped structure, which is costly.

[0049] Please combine Figures 5 to 7 , Figure 5 for Figure 3 The diagram shown is a three-dimensional representation of the support frame from a fourth-person perspective. Figure 6 for Figure 4 The diagram shows a planar structure of the support frame. Figure 7 for Figure 6 A cross-sectional view along the AA direction. Therefore, in this embodiment, in order to reduce the manufacturing cost of the support frame 2 while improving its structural strength, a recess 241 and a reinforcing structure 3 are provided on the first surface 21. The reinforcing structure 3 is disposed in the recess 241, wherein the recess 241 is recessed in a direction away from the first cavity 111 along the axial direction of the cylinder 1.

[0050] Thus, by strengthening the structure 3, the structural strength of the first surface 21 can be enhanced, thereby allowing the first surface 21 to withstand greater force from the clothing. This enhances the structural strength of the support frame 2, extends its service life, and consequently extends the service life of the tube assembly 10 provided in this embodiment.

[0051] Furthermore, by providing a recess 241 on the first surface 21, the overall weight of the support frame 2 can be reduced, and the amount of raw materials used in the support frame 2 can be reduced, thereby reducing the manufacturing cost of the support frame 2.

[0052] In some specific embodiments, the reinforcing structure 3 includes a reinforcing rib 31 disposed on the first surface 21. The reinforcing rib 31 can be disposed on the first surface 21 by means of integral molding with the support frame 2 or by welding, and no specific limitation is made here.

[0053] The following will further introduce the above-mentioned reinforcing structure 3 in conjunction with the specific structure of the support frame 2.

[0054] In some implementations, the support frame 2 includes a connecting part 23 and at least three support arms 24. The support arms can be three, four or five, and the specific number is not specifically limited here.

[0055] The following is described with three support arms 24.

[0056] Specifically, the support frame 2 comprises a connecting portion 23 and three support arms 24, the connecting portion 23 has a connecting hole 231 for rotationally connecting with a connecting shaft, the connecting shaft is a connecting shaft on a driving mechanism for driving the rotation of the drum assembly 10, the rotation of the drum assembly 10 is realized through the rotational connection between the connecting shaft and the connecting hole 231, so that the clothes in the drum 1 can be washed.

[0057] The three support arms 24 are connected to the circumferential side of the connecting portion 23 and are uniformly distributed at intervals, that is, the included angle between two adjacent support arms 24 is 120 degrees.

[0058] The end of the connecting portion 23 facing the first cavity opening 111 and the end of the three support arms 24 facing the first cavity opening 111 jointly constitute the first face 21, and the end of the connecting portion 23 away from the first cavity opening 111 and the end of the three support arms 24 away from the first cavity opening 111 jointly constitute the second face 22.

[0059] Each support arm 24 is formed with a recess 241, and at least one reinforcing rib 31 is arranged in each recess 241. That is, the end of each support arm 24 facing the first cavity opening 111 is provided with a recess 241 and a reinforcing rib 31 arranged in the recess 241. In this way, the manufacturing cost of each support arm 24 is relatively small, and the structural strength is relatively large. Thus, the manufacturing cost of the support frame 2 can be greatly reduced and the structural strength of the support frame 2 can be greatly increased.

[0060] It can be understood that the three support arms 24 mainly support the drum 1, so in the specific embodiment, the reinforcing ribs 31 are only arranged on the support arms 24, so that the structure of the support frame 2 is reinforced while the manufacturing cost of the support frame 2 is relatively small.

[0061] In some optional embodiments, in order to facilitate the molding of the recess 241 and the arrangement of the reinforcing rib 31, the support arm 24 extends in the radial direction of the connecting hole 231; the extension direction of the recess 241 and the extension direction of the reinforcing rib 31 are consistent with the extension direction of the support arm 24. That is, the recess 241 and the reinforcing rib 31 also extend in the radial direction of the connecting hole 231. In this way, the recess 241 is easily formed on the support arm 24, and the reinforcing rib 31 is easily welded with the support arm 24.

[0062] In order to realize the connection between the support arm 24 and the drum 1, a part for connection should be reserved at the end of the support arm 24 close to the drum 1, therefore, the extension length of the above-mentioned recess 241 should be less than the extension length of the support arm 24.

[0063] Due to the shape limitations of the main structure of the support arm 24, in some embodiments, in order to improve the structural strength of the support arm 24, reinforcing plates 25 can be provided in the reinforcing grooves 242 on opposite sides of the support arm 24, and multiple reinforcing plates 25 can be provided in one reinforcing groove 242, and the multiple reinforcing plates 25 are arranged at intervals along the extension direction of the support arm 24.

[0064] Furthermore, to avoid the reinforcing rib 31 affecting other structural components or modules within the garment handling device, in some embodiments, the size of the reinforcing rib 31 is less than or equal to the depth of the recess 241 in the groove depth direction. This ensures that the reinforcing rib 31 does not protrude from the first surface 21, allowing the tube assembly 10 to rotate smoothly during operation of the garment handling device.

[0065] In some embodiments, to avoid stress concentration, edge portions 245 are formed on opposite sides of the recess 241 in the width direction of each support arm 24; the dimension of the edge portion 245 in the width direction of the support arm 24 is greater than or equal to 3 mm. In this way, there are solid structures on both sides of the recess 241, and the edge portions 245 can share the force borne by the recess 241, so as to avoid stress concentration to a certain extent and further improve the structural strength of the support frame 2.

[0066] In some embodiments, to improve the stability of the support frame 2, the middle part of the support frame 2 can be recessed towards the first cavity opening 111. Therefore, please refer to... Figures 8 to 10 , Figure 8 for Figure 3 The diagram shows a planar structure of the support frame. Figure 9 for Figure 8 Cross-sectional view along the BB direction. Figure 10 for Figure 6 A cross-sectional view along the CC direction. In a specific embodiment of this invention, the two ends of the support arm 24 are a connecting end 243 and a support end 244, respectively. The connecting end 243 is connected to the connecting part 23, and the support end 244 is connected to the cylinder 1. In the axial direction of the connecting part 23, the connecting end 243 is positioned closer to the first cavity opening 111 than the support end 244.

[0067] This will cause the connecting end 243 and the connecting part 23 to be recessed toward the side of the first cavity 111, thereby improving the structural stability of the support frame 2 and enabling the support frame 2 to support the cylinder 1 more effectively. During the operation of the clothing processing device, the vibration of the cylinder 1 and the noise generated by the rotation of the cylinder 1 will be reduced.

[0068] It should be noted that the connecting end 243 not only needs to be connected with the connecting portion 23, but also needs to be transitionally connected with the connecting end 243 in the adjacent support arm 24, so that the connecting portion of the two adjacent support arms 24 is also recessed towards the side close to the center of the connecting hole 231, so as to improve the structural strength of the support frame 2.

[0069] The connecting mode between the support end 244 and the cylinder 1 can be that two installation holes 2441 are arranged on the support end 244 in a spaced manner, and the cylinder 1 and the support frame 2 can be connected together through threaded fasteners penetrating the installation holes 2441 and the cylinder 1. In some other embodiments, the support end 244 and the cylinder 1 can also adopt other connecting modes, such as welding, etc. Herein, the connecting mode between the support end 244 and the cylinder 1 is not specifically limited.

[0070] From the above, it can be known that at least one reinforcing rib 31 is arranged in each recess 241, that is, only one reinforcing rib 31 can be arranged in each recess 241, or a plurality of reinforcing ribs 31 can be arranged in each recess 241. The two embodiments will be introduced respectively as follows.

[0071] As shown in Figure 3 , Figure 5 , Figure 8 and Figure 9 , in an embodiment, a first reinforcing rib 311 is arranged in each recess 241, and the first reinforcing rib 311 extends along the extension direction of the support arm 24; the first reinforcing rib 311 has two side walls 3111 arranged in a spaced manner along the width direction of the support arm 24, and the two adjacent side walls 3111 in the two adjacent first reinforcing ribs 311 in the adjacent two recesses 241 are connected through the arc-shaped wall 32.

[0072] In this way, the three first reinforcing ribs 311 can be connected together, and the arc-shaped wall 32 can disperse the force borne by the three first reinforcing ribs 311, so as to avoid that more force is concentrated on the three first reinforcing ribs 311. Therefore, the structural strength of the support frame 2 can be further improved.

[0073] Among them, the central axis of the first reinforcing rib 311 coincides with the central axis of the support arm 24.

[0074] As shown in Figure 4 , Figure 6 , Figure 7 and Figure 10As shown, in another embodiment, not only is the first reinforcing rib 311 arranged in each recess 241, but a second reinforcing rib 312 is also arranged on the opposite side of the first reinforcing rib 311, the second reinforcing rib 312 extends along the extension direction of the support arm 24, and the second reinforcing ribs 312 on the opposite sides of the first reinforcing rib 311 are arranged in axial symmetry with respect to the first reinforcing rib 311; the two adjacent second reinforcing ribs 312 in two adjacent recesses 241 are connected by an arc-shaped connecting rib 33.

[0075] In this way, the arc-shaped connecting rib 33 connected between the two second reinforcing ribs 312 can disperse the stress of the two second reinforcing ribs 312, so as to avoid more force being distributed on the second reinforcing rib 312. Thus, the structural strength of the support frame 2 can be further improved.

[0076] The present embodiment also provides a clothes treatment device, which comprises a driving mechanism and the drum assembly 10 in the above embodiment; the driving mechanism has a connecting shaft, the connecting shaft is rotationally connected with the support frame 2, and the driving mechanism is used to drive the support frame 2 and the drum 1 to rotate synchronously. That is to say, during the operation of the clothes treatment device, the connecting shaft is rotated by the driving mechanism, and then the support frame 2 and the drum 1 are driven to rotate together, so as to wash the clothes in the drum 1.

[0077] It should be noted that the driving mechanism can comprise a motor, a belt wheel assembly, etc. Herein, the structure of the driving mechanism is not specifically limited.

[0078] Further, the clothes treatment device provided by the present embodiment can also comprise other structures or components such as an outer drum, etc., which are not limited herein.

[0079] The clothes treatment device provided by the present embodiment has a long service life by adopting the above-mentioned drum assembly 10.

[0080] The above only describes the preferred embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation, direct / indirect application in other related technical fields based on the content of the present application and the drawings, or the like, are included in the patent protection scope of the present application.
