[0034] 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.

[0035] 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.

[0036] 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.

[0037] refer to Figures 1 to 8, an embodiment of the present invention provides a multi-barrel fixed connection structure for fixing a plurality of laundry processing barrels 20 arranged in an upper and lower direction, wherein the plurality of laundry processing barrels 20 are arranged axially parallel on the multi-barrel fixed connection structure, and the multi-barrel fixed connection structure includes a pair of separate connection frames 10 arranged relatively front and back, each connection frame 10 includes at least one first connection portion arranged in its height direction for fixing at least two laundry processing barrels 20 and at least one second connection portion located below the first connection portion, the pair of first connection portions and the pair of second connection portions are separated in the height direction along the axial direction of the laundry processing barrel 20 The two connecting frames 10 are arranged in pairs and opposite to each other, and are fixedly connected to the two ends of the two clothing treatment barrels 20 in the front-to-back direction. The two ends are consistent with the direction of the aforementioned relative front-to-back spacing, that is, both are on the front and back sides of the central extension line of the barrel mouth, so that the clothing treatment barrels 20 are pressed between a pair of split connecting frames 10 that are relatively spaced apart from each other. A portion of each clothing treatment barrel 20 is located in the spacing space between the pair of connecting frames 10. In other words, the two split connecting frames press and fix each clothing treatment barrel 20 in the front-to-back direction, thereby achieving a connection with high stability and firmness for each clothing treatment barrel 20. In addition, when it is necessary to fix three clothing treatment barrels 20, another first connecting portion or another second connecting portion can be provided in the gap between the first connecting portion and the second connecting portion to fix another clothing treatment barrel. It can be understood that the volume of the other clothing treatment barrel is relatively small so that it can be accommodated in the above-mentioned gap. The above-mentioned connecting frame 10 can be made of rigid materials such as stainless steel and aluminum alloy, and has high rigidity. Therefore, by adopting a pair of separate and relatively spaced connecting frames 10, the rigidity of each clothing processing barrel 20 during operation can be improved, and the two clothing processing barrels 20 can be fixedly connected in a span, so that the vibration of the clothing processing barrel 20 at a position far away from the horizontal support surface of the clothing processing device during operation can be reasonably transitioned, and the vibration energy is transferred downward through the connecting frame 10, and the left and right vibration amplitude of each clothing processing barrel 20 during operation is reduced, which is beneficial to the smooth operation of the entire clothing processing device. In addition, the pair of connecting frames 10 are set to be separate, and the distance between the two can be flexibly set according to the clothing processing barrels 20 with different axial sizes that need to be connected and fixed, so that it has high applicability.

[0038] Key References Figure 1 and Figure 3In one embodiment, each connecting frame 10 includes a pair of first beams 11 extending in the vertical direction and second beams 12 respectively connected to the pair of first beams 11 at right angles. In addition, it can also be set to have more than two first beams and more than one second beam, and the second beam 12 can be connected to the first beam 11 by welding, threading, etc. In this embodiment, each first beam 11 and second beam 12 together form a hollow roughly rectangular parallelepiped shape. In addition, it can be understood that the above-mentioned two first beams 11 can also have other arrangements in the height direction, for example, the two first beams 11 can be arranged crosswise, and correspondingly, the second beam 12 is arranged between the two crossed first beams 11. A first connecting portion and a second connecting portion are provided at both ends of the two first beams 11 of each connecting frame 10 relative to each other. That is, the first connecting portion and the second connecting portion respectively connect and fix the two ends of the above-mentioned two first beams 11. The two clothing processing barrels 20 can have a washing function and a drying function respectively, or both have washing and drying functions 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 above-mentioned first connecting part and the second connecting part are respectively configured as multifunctional connecting parts 13 with an arc-shaped opening 13A. Each multifunctional connecting part 13 can be connected to the corresponding first beam 11 by welding, threaded connection, etc., and each multifunctional connecting part 13 is configured to have a larger area than the second beam 12. Therefore, each multifunctional connecting part 13 can connect the first beam 11, counterweight the overall multi-barrel fixed connection structure, and strengthen the rigidity of the connecting frame 10. The two pairs of multifunctional connecting parts 13 located at the top and bottom ends in the height direction respectively form a pair of first connecting parts and a pair of second connecting parts, and their respective arc-shaped openings 13A respectively support the outer periphery of the corresponding clothing processing barrel 20 in a corresponding manner. Since the arc-shaped opening 13A is similar to the outer periphery of the clothing processing barrel 20, the multifunctional connecting part 13 has good stability in supporting the clothing processing barrel 20. Therefore, the above-mentioned multifunctional connecting parts 13 can not only strengthen the rigidity of the connecting frame 10 in which they are located, but also jointly achieve the function of well supporting the clothing processing barrel 20. Furthermore, each laundry processing tub 20 is secured to a corresponding multifunctional connector 13 via a plurality of securing assemblies. Thus, the securing assemblies securely connect each laundry processing tub 20 to the corresponding multifunctional connector 13. Furthermore, when assembling two laundry processing tubs 20, only the tubs 20 need to be positioned upward or downward toward the two arc-shaped openings 13A, thereby improving assembly efficiency and reducing assembly costs.

[0039] Key References 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 and the multifunctional connector 13 are provided with multiple pairs of tapered holes 21 and through holes 13B, each for a tapered bolt 31 to pass through. 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. The end of the tapered bolt 31 opposite the threaded end 32 is equipped with a nut 33 with a notch 34. The laundry tub 20 is provided with a boss 22 that abuts against the notch 34. Consequently, the notch 34 of the nut 33 engages with the boss 22 of the laundry tub 20. When tightening the tapered bolt 31, the notch 34 and boss 22 restrain each other 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 multifunctional connector 13 to prevent the fixing nut 35 from squeezing and deforming the multifunctional connector 13 when tightened, thereby improving the tightening effect. Furthermore, multiple through-holes 13B are evenly distributed across each multifunctional connector 13. This ensures that the fixing force applied to each laundry tub 20 is uniform, thereby improving the fixing stability.

[0040] Key References Figure 3 In one embodiment, the multifunctional connector 13 is configured as a first multifunctional connector 13' and a second multifunctional connector 13", corresponding to the first connecting portion and the second connecting portion. The first multifunctional connector 13' is a solid plate, and the second multifunctional connector 13" is a hollow plate. Since the first multifunctional connector 13' is configured as a solid plate, its strength in supporting and fixing the laundry processing tub 20 is improved. Since the second multifunctional connector 13" is configured as a hollow plate, the hollow portion of the hollow plate can buffer and weaken the vibration force exerted by the laundry processing tub 20 supported and fixed by the first multifunctional connector 13' on the laundry processing tub 20 fixed by the second multifunctional connector 13" during operation, thereby improving the overall stability of the multi-tub fixed connection structure. Moreover, the different solid and hollow configurations facilitate weight balancing of the overall multi-tub fixed connection structure. In addition, the first and second multifunctional connectors 13', 13" are each fixed to a second beam 12 on the side opposite to their respective arc-shaped openings 13A, thereby further increasing the fixing strength of the first and second multifunctional connectors 13', 13" to the laundry processing tub 20.

[0041] Further key references Figure 1 、 Figure 7 and Figure 8In one embodiment, the multi-barrel fixed connection structure further includes a reinforcing connecting beam assembly 40. At least one reinforcing connecting beam assembly 40 is fixedly connected between a pair of connecting frames 10 and between each pair of opposing first beams 11, thereby fixedly connecting the pair of separate connecting frames 11 to improve the overall stability and rigidity of the multi-barrel fixed connection structure. In addition, at least one reinforcing connecting beam assembly 40 can be fixedly connected between the two first beams 11 of each connecting frame 10, thereby improving the rigidity of each connecting frame 10.

[0042] In one embodiment, the above-mentioned reinforced connecting beam assembly 40 includes a reinforced connecting beam body 41, a transfer screw 43, a first transfer nut 44 and a second transfer nut 45. The two ends of the reinforced connecting beam body 41 can be fixed with a first transfer nut 44 by welding, threaded connection, etc. 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 a corresponding second transfer nut 45, thereby fastening the reinforced beam body 41 to the connecting frame 10, thereby improving the overall stability of the connecting frame 10.

[0043] In one embodiment, the above-mentioned reinforced connecting beam assembly 40 also includes an angle code 42, a fastening bolt 46 and a fastening nut 47. At least one angle code 42 is set at the two ends of the reinforced connecting beam body 41 where they are fixedly connected to a first beam 11. That is, a pair of adjacent vertically parallel first beams 11 are fixed to at least one angle code 42. The fixing method for each angle code 42 is as follows: the fastening bolt 46 is passed through the angle code 42 and the first beam 11 in turn and tightened with the fastening nut 47, and the first connection end face of the angle code 42 is fixedly connected to the first beam 11. The fastening bolt 46 is passed through the angle code 42 and the reinforced connecting beam body 41 in turn and tightened with the fastening nut 47, and the second connection 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, thereby further enhancing the fastening between the beam body 41 and the connecting frame 10.

[0044] 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 adapter 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 adapter 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. The above two limiting effects and the combination of the structural form of the angle code 42 improve the rigidity of the multi-barrel fixed connection structure.

[0045] 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 the connecting frame 10 caused by assembly errors.

[0046] In one embodiment, both ends of each of the above-mentioned reinforcing beam bodies are configured to be elastically retractable toward the center. For example, a spring can be provided inside each reinforcing beam body, with both ends elastically connected to the two ends of the limiting groove arranged on the above-mentioned reinforcing beam body. In this way, each reinforcing beam body can adapt to various pairs of connecting frames with different spacing distances through telescopic deformation and be fixedly connected to them, thereby further improving the applicability to clothing processing barrels 20 with different sizes.

[0047] Key References Figure 1 In the height direction of each connecting frame 10, the corner codes 42 of the pair of reinforced connecting beam assemblies 40 located above are each set as a pair, and the corner codes 42 of the pair of reinforced connecting beam assemblies 40 located below are each set as two pairs. In the case of two pairs of corner codes 42, each pair of corner codes 42 is respectively and relatively arranged on both sides of the two ends of the reinforced connecting beam body 41, that is, each corner code 42 is arranged at a right angle position where the reinforced connecting beam body 41 is connected and perpendicular to the connecting frame 10. This can enhance the overall rigidity of each connecting frame 10, effectively curb the torsion in different directions of each connecting frame 10 generated during the operation of the clothing processing barrel 20, greatly reduce and improve the transmission of vibration energy, and make the entire clothing processing device run more smoothly. For a pair of angle brackets 42 located on the same side of the reinforced connecting beam body 41, a fastening bolt 46 is passed through one of the angle brackets 42, the reinforced connecting beam body 41, the other angle bracket 42 and then tightened with a fastening nut 47, so that the two second connection end faces of the pair of angle brackets 42 are fixedly connected to the reinforced connecting beam body 41 through the same fastening bolt 46 and the same fastening nut 47, which simplifies the assembly steps and saves time.

[0048] Further preferably, the spacing span between the first connecting portion and the second connecting portion is 370 mm to 1182 mm. The specific numerical range of the spacing span is obtained through multiple experiments by the inventor. It not only allows users of different heights to obtain higher comfort when using different clothing processing tubs, but also sets a reasonable numerical range based on the weight, working vibration, etc. of the two adjacent clothing processing tubs, so that the two adjacent clothing processing tubs 20 can be fixedly connected with a large span with high connection stability and good connection firmness.

[0049] Key References Figure 2 Another embodiment of the present invention provides a clothing processing device, which includes two clothing processing barrels 20 and any of the above multi-barrel fixed connection structures. The two clothing processing barrels 20 are fixedly connected to a pair of first connecting parts and a pair of second connecting parts respectively. The clothing processing device can obtain the beneficial effects of any of the above multi-barrel fixed connection structures, which will not be repeated here.

[0050] In one embodiment, the clothing processing device further includes a support frame 50 disposed on the periphery of the multi-barrel fixed connection structure and three clothing processing tubs 20. The three clothing processing tubs 20 include an upper clothing processing tub, a middle clothing processing tub, and a lower clothing processing tub. The upper clothing processing tub and the lower clothing processing tub are disposed above and below a pair of connection frames 10, respectively. The middle clothing processing tub is disposed in a gap between the pair of connection frames 10 and is connected and fixed to the support frame 50. The upper clothing processing tub and the lower clothing processing tub are connected and fixed via the multi-barrel fixed connection structure. This not only achieves a compact structure for the connection and fixation of the three clothing processing tubs, but also reduces the mutual influence of the three clothing processing tubs during operation by relatively independently connecting and fixing the middle clothing processing tub to the support frame 50, thereby improving the operating stability of the clothing processing device.
