[0002] At present, most traditional drum washing machines in clothing processing devices have only one washing drum. With the strengthening of people's hygiene awareness, more and more users need to wash different types of clothes separately or wash a small amount of clothes in time. Therefore, users are no longer satisfied with the traditional drum washing machine of "one drum washing" and have put forward healthier washing requirements: one machine for multiple washes, that is, one washing machine can effectively distinguish between regular clothes, underwear and baby clothes, etc. and wash them separately. In order to meet the above healthier washing requirements, the existing clothing processing device provides a duplex multi-barrel washing machine. Since two or more washing drums are accommodated in one box at the same time, the connection and fixation between two adjacent washing drums is the key to the stable operation of the whole machine. The existing two-barrel connection method uses threads as the connection and counterweight between the barrels. However, this connection method has the problems of being unable to achieve large-span connection, low connection stability and poor connection firmness. Summary of the Invention

[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0037] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] refer to Figures 1 to 8 An embodiment of the present invention provides a multi-barrel fixed connection structure that can install multiple clothing treatment barrels with a large span. The span refers to the installation distance between the multiple barrels, which is specifically reflected in the spacing span between the first installation position and the second installation position. The preferred spacing span that can reflect better technical effects is 370mm to 1182mm. The specific value of the spacing span is obtained through multiple experiments by the inventor. It not only allows users of different heights to use different clothing treatment barrels with high comfort, but also sets the reasonable value range based on the weight, working vibration, etc. of the two adjacent clothing treatment barrels. In addition, the fixed connection of two adjacent clothing treatment barrels with a large span has the advantages of high connection stability and good connection firmness.

[0039] Specifically, such as Figure 1As shown, the multi-barrel fixed connection structure includes a pair of connection frames 10 arranged relatively at intervals, each connection frame 10 includes two first beams 11 extending parallel to each other in the vertical direction in the height direction, and a first multifunctional connector 13 with a first connection part and a second multifunctional connector 14 with a second connection part are relatively provided at both ends of the two first beams 11. The first multifunctional connector 13 and the second multifunctional connector 14 are preferably set to be plate-shaped, and a pair of first connection parts and a pair of second connection parts respectively form a clothing processing barrel mounting position, wherein the first mounting position of a pair of first connection parts is fixedly connected to the two ends of a clothing processing barrel 20 upward, and the second mounting position of a pair of second connection parts is fixedly connected to the two ends of another clothing processing barrel 20 downward. The two clothing processing barrels 20 can respectively have a washing function and a drying function or both have a washing and drying function at the same time. For the clothing processing barrel 20 with a washing function, it includes an inner barrel for holding clothes and an outer barrel for holding washing water. The multi-tub fixed connection structure also includes at least two second beams 12, each connected between the middle and upper portions of the first beams 11 of two spaced-apart connecting frames 10. Positioning the second beams between the middle and upper portions of the first beams 11 further enhances the stability of the laundry tubs 20 when mounted on the connecting frames over a wide span. Each connecting frame 10 and each second beam 12 of the multi-tub fixed connection structure are constructed from rigid materials such as stainless steel and aluminum alloy, resulting in high rigidity. This improves the rigidity of each laundry tub 20 during operation, resulting in a highly stable and robust multi-tub fixed connection structure. Furthermore, since the first and second mounting locations securely connect a laundry tub 20 at the upper and lower positions of a pair of connecting frames at the aforementioned spacing, two laundry tubs 20 can be securely connected over a wide span. This effectively transfers vibrations from laundry tubs 20 located farther from the horizontal support surface of the laundry treatment device during operation, transferring vibration energy downward through the connecting frames 10 and reducing the amplitude of left-right vibrations of each laundry tub 20 during operation. This contributes to smooth operation of the entire laundry treatment device, minimizing vibration and noise. In addition, when three laundry processing tubs 20 need to be fixedly connected, it is only necessary to refer to the above description and add a pair of connecting frames 10, at least two second beams and corresponding structures.

[0040] Key References Figure 3In one embodiment, the first connecting portion includes a first opening 13A having a first curved surface, and the second connecting portion includes a second opening 14A having a second curved surface. Each laundry processing tub 20 is secured to the first multifunctional connector 13 and the second multifunctional connector 14 via a plurality of fixing assemblies. These fixing assemblies securely connect each laundry processing tub 20 to its corresponding multifunctional connector with high stability. Because the first opening 13A and the second opening 14A have different curved surfaces, even if the two laundry processing tubs 20 apply torque to the multi-tub fixed connection structure through the two multifunctional connectors during operation, the two different curved surfaces can separate the areas where the two torques are applied, thereby preventing the same portion of the multi-tub fixed connection structure from being simultaneously subjected to the forces of the two torques. This enhances the support strength of the multi-tub fixed connection structure. Furthermore, because the thickness and shape of the two multifunctional connectors can be differentiated, they can act as a counterweight for the entire multi-tub fixed connection structure.

[0041] In one embodiment, the first curved surface is configured as a first curved surface 13A1 having an overall first curvature. The second curved surface includes a central concave surface 14A1 and symmetrically disposed second curved surfaces 14A2 having a second curvature on either side of the central concave surface 14A1. Each first curved surface 13A1 adaptively supports the curved outer periphery (not shown) of a laundry processing tub 20 located vertically above, and each central concave surface 14A1 and each second curved surface 14A2 adaptively supports the convex outer periphery (not shown) and the curved outer periphery (not shown) of another laundry processing tub 20 located vertically below. Therefore, by configuring the second curved surface to have a central concave surface, the central concave surface abuts the convex outer periphery of the lower laundry processing tub 20. This not only further prevents circumferential displacement of the laundry processing tub 20, but also further disperses the torque generated by the lower laundry processing tub 20, thereby preventing stress concentration caused by the torque from reducing the stability of the multi-tub fixed connection structure.

[0042] In one embodiment, each first multifunctional connector 13 and each second multifunctional connector 14 is configured to have a larger area than other second beams 12. Therefore, each multifunctional connector can further enhance the rigidity of each connecting frame 10, and also increase the flexibility of the counterweight by configuring each multifunctional connector to have a different relative area.

[0043] In one embodiment, the second multifunctional connector 14 further includes a reinforcing connector 16 disposed opposite to the second opening 14A and connected to a first beam 11 at both ends. The reinforcing connector 16 is preferably configured as a rod, thereby increasing the stability of the large-span installation of multiple clothing processing barrels.

[0044] Key References Figure 2 and Figures 4 to 6In one embodiment, the fixing assembly is a tapered bolt assembly 30, which includes a tapered bolt 31 and a fixing nut 35. The laundry treatment tub 20, the first multifunctional connector 13, and the second multifunctional connector 14 are correspondingly provided with multiple pairs of tapered holes 21 and through holes 15 for respectively passing a tapered bolt 31. The threaded end 32 of each tapered bolt 31 is tightened with a fixing nut 35. Therefore, the tapered surfaces of the tapered bolt 31 and the tapered hole 21 cooperate with each other, thereby increasing the contact area between the tapered bolt 31 and the laundry treatment tub 20 and reducing the surface stress at the fixed connection between the tapered bolt 31 and the laundry treatment tub 20. Furthermore, a nut 33 with a notch 34 is provided at the end of the tapered bolt 31 opposite the threaded end 32. The laundry tub 20 is provided with a boss 22 that abuts against the notch 34. Consequently, the notch 34 of the nut 33 mates with the boss 22 of the laundry tub 20. As a result, when the tapered bolt 31 is tightened, the notch 34 and boss 22 are mutually restrained during the process of tightening the nut with a sleeve, preventing the tapered bolt 31 from rotating during tightening and reducing assembly difficulty. Furthermore, a spring washer 36 can be provided between the fixing nut 35 and the first or second multi-functional connector 13, 14. This prevents the fixing nut 35 from extruding and deforming the first or second multi-functional connector 13, 14 when tightened, thereby improving the tightening effect.

[0045] Key References Figure 3 In one embodiment, the through holes 15 are arranged at equal intervals in the horizontal direction, that is, the horizontal projections of the through holes 15 in the same vertical plane are located on the same straight line, and the distances between adjacent through holes are equal. In this way, the fixing force on each clothing processing tub 20 can be uniform. A through hole 15 is provided at the end where each first beam 11 is adjacent to the corresponding second multi-functional connecting member 14. In this way, the supporting force of each first beam on the upper clothing processing tub 20 is improved, and the vibration caused by the upper clothing processing tub 20 to the lower clothing processing tub 20 can be reduced.

[0046] Key References Figure 2 and Figure 3 In one embodiment, the multi-barrel fixed connection structure further includes at least two reinforcing connecting beam assemblies 40. Each reinforcing connecting beam assembly 40 is disposed parallel to the second beam 12 located between the first beams 11 of two spaced-apart connecting frames 10. Therefore, the provision of each reinforcing connecting beam assembly 40 strengthens the fixed connection between the pair of connecting frames 11, thereby improving the overall stability and rigidity of the multi-barrel fixed connection structure.

[0047] Key References Figure 2 、 Figure 7 and Figure 8In one embodiment, the reinforcing connecting beam assembly 40 includes a reinforcing connecting beam body 41 and an angle code 42, a transfer screw 43, a first transfer nut 44, a second transfer nut 45, a fastening bolt 46 and a fastening nut 47. The two ends of the reinforcing connecting beam body 41 can be fixed with a first transfer nut 44 by welding, threading, etc., and both ends of the transfer screw 43 are provided with threads, and one end is tightened with the first transfer nut 44, and the other end passes through a through hole (not shown) provided on the first beam 11 and is tightened with the second transfer nut 45, thereby fastening the connecting frame 10 to the reinforcing beam body 41. At the places where the two ends of the reinforcing connecting beam body 41 are fixedly connected to the first beam 11, At least one angle code 42 is provided, that is, a pair of adjacent vertically parallel first beams 11 are each fixed to at least one angle code 42, and the fixing method for each angle code 42 is as follows: a fastening bolt 46 is passed through the angle code 42 and the first beam 11 in sequence and is tightened with the fastening nut 47, and the first connecting end face of the angle code 42 is fixedly connected to the first beam 11, and a fastening bolt 46 is passed through the angle code 42 and the reinforced connecting beam body 41 in sequence and is tightened with the fastening nut 47, and the second connecting end face of the angle code 42 is fixedly connected to the reinforced connecting beam body 41. The above-mentioned fastening bolts 46 respectively play the role of connecting the angle code 42 and the first beam 11 and connecting the angle code 42 and the reinforced connecting beam body 41. As described above, by fixing the reinforced connecting beam assembly 40 on a pair of connecting frames 10, the torsional resistance of each connecting frame 10 is improved when each clothing processing barrel 20 is in operation, and the fastened fastening bolts 46 and the fastened transition screws 43 located at the first end fixed by the angle code 42 can jointly limit the assembly movement in the upper and lower directions between the connecting frame 10 and the reinforced connecting beam body 41, and the fastened fastening bolts 46 and the fastened transition screws 43 located at the second end fixed by the angle code 42 can jointly limit the assembly movement in the left and right directions between the connecting frame 10 and the reinforced connecting beam body 41. Through the above two limiting effects and combined with the structural form of the angle code 42, the rigidity of the multi-barrel fixed connection structure is improved.

[0048] In one embodiment, limiting grooves 48 are provided at both ends of the reinforced connecting beam body 41, and a first adapter nut 44 is fixed in each limiting groove 48 by welding. Therefore, the limiting groove 48 can limit the assembly accuracy of the first adapter nut 44, reduce assembly errors, and avoid vibration of each connecting frame 10 caused by assembly errors.

[0049] Key References Figure 1The reinforced connecting beam assembly 40 includes two pairs of angle brackets 42. Each pair of angle brackets 42 is positioned oppositely on either side of the reinforced connecting beam body 41. That is, each angle bracket 42 is positioned at a right angle to the reinforced connecting beam body 41 and perpendicular to each connecting frame 10. This strengthens the overall rigidity of each connecting frame 10, effectively curbing the torsion in different directions caused by the laundry processing tub 20 during operation, significantly reducing and improving the transmission of vibration energy, and ensuring smoother operation of the entire laundry processing device. For a pair of angle brackets 42 located at the same end of the reinforced connecting beam body 41, a fastening bolt 46 is sequentially passed through one of the angle brackets 42, the reinforced connecting beam body 41, and the other angle bracket 42, and then tightened with a fastening nut 47. Thus, the two second connection end faces of the pair of angle brackets 42 are fixedly connected to the reinforced connecting beam body 41 via the same fastening bolt 46 and the same fastening nut 47, simplifying the assembly process and saving time.

[0050] Key References Figure 3 In one embodiment, the connecting frames 10 and the second beams 12 of the multi-tub fixed connection structure are integrally formed from a rigid material such as stainless steel or aluminum alloy. This integral forming process can be achieved through stamping, die casting, or other methods. This integral forming process reduces unit production costs and significantly improves production efficiency. Furthermore, even if the multi-tub fixed connection structure experiences vertical vibration due to the operation of the laundry tub 20 thereon, the rigid, integrally formed pair of connecting frames 10 can reduce the shear and bending loads at the interface between the tapered bolts 31 and the tapered holes 21, thereby increasing the safety factor of the tapered bolt assembly 30 securing the laundry tub 20. Furthermore, because the connecting frames 10 and the second beams 12 that securely connect them are integrally formed from a rigid material, bolts or welding, etc., are eliminated between the first beam 11 and the second beam 12, thereby eliminating the risk of failure of the bolts or welding fastening methods on the connecting frames 10 due to vibration generated by the operation of the laundry tub 20.

[0051] In one embodiment, the spacing span between the first mounting position and the second mounting position is 370 mm to 1182 mm. The specific numerical range of the spacing span not only meets the needs of large-span fixed connection, but also ensures high connection stability and good connection firmness of the large-span fixed connection.

[0052] Key References Figure 2Another embodiment of the present invention provides a clothing processing device, which includes any one of the above multi-barrel fixed connection structures, a support frame 50 arranged on the periphery of the multi-barrel fixed connection structure, and three upper, middle and lower clothing processing barrels arranged in sequence up and down, the upper and lower clothing processing barrels are fixedly connected to the above-mentioned pair of first connecting parts and the pair of second connecting parts respectively, and the middle clothing processing barrel is arranged in the gap in the middle position of the pair of connecting frames 10 and is connected and fixed to the support frame 50. In this way, not only the connection and fixation of the three clothing processing barrels is compact, but also by relatively independently connecting and fixing the middle clothing processing barrel to the support frame 50, the mutual influence of the three clothing processing barrels during operation is reduced, thereby improving the working stability of the clothing processing device.
