[0034] Refer to the following Figures 1 to 8 The first embodiment of the present invention will be described in detail.

[0035] like Figure 1 and Figure 2 As shown, the cover assembly of the present invention mainly includes a cover body 1, a connecting rib 2, a first columnar structure 3, a fixing plate 4, a second columnar structure 5, a pin shaft 7 and a torsion spring 8.

[0036] like Figure 3 and Figure 4As shown, the cover body 1, the connecting rib 2 and the first columnar structure 3 are integrally formed by a bending process, and the connecting rib 2 is located between the cover body 1 and the first columnar structure 3. In addition, those skilled in the art may also connect the cover body 1, the connecting rib 2 and the first columnar structure 3 together in any other feasible manner as needed, such as welding, riveting, screw connection, or integrally forming the cover body 1, the connecting rib 2 and the first columnar structure 3 by casting.

[0037] Continue reading Figure 3 and Figure 4 , one end of the cover body 1 is provided with two first columnar structures 3 distributed along the axial spacing, and each first columnar structure 3 is provided with three connecting ribs 2 between the cover body 1. Further, each first columnar structure 3 is a hollow structure. It can be understood by those skilled in the art that the number of the first columnar structures 3 and the connecting ribs 2 can also be any other number, for example, the first columnar structure 3 is set to one, three, four, etc., and the connecting ribs 2 are set to two, three, four, etc.

[0038] like Figure 5 and Figure 6 As shown, the fixing plate 4 and the second columnar structure 5 are also made in one piece by a bending process. Those skilled in the art may also connect the fixing plate 4 and the second columnar structure 5 together by any other feasible method as needed, such as welding, riveting, screw connection, or forming the fixing plate 4 and the second columnar structure 5 in one piece by casting.

[0039] Continue reading Figure 5 and Figure 6 , six second columnar structures 5 distributed along the axial distance are provided at one end of the fixing plate 4. Each second columnar structure 5 is a hollow structure, and a strip-shaped opening 51 is formed on the side wall of each second columnar structure 5 along the axial direction, so that the cross-section of the second columnar structure 5 along the radial direction is C-shaped. Among them, the width of the strip-shaped opening 51 perpendicular to the axial direction of the second columnar structure 5 is greater than the thickness of the connecting rib 2, so as to allow the connecting rib 2 to slide in the strip-shaped opening 51. Furthermore, the axial distance between two adjacent second columnar structures 5 is greater than the axial width of the connecting rib 2 along the first columnar structure 3, so that a connecting rib 2 (such as Figure 1 and Figure 2 Furthermore, except for the two middle second columnar structures 5, a stopper structure 6 is provided between the other two adjacent second columnar structures 5. The stopper structure 6 is used to stop the connecting rib 2 to prevent the cover body 1 from turning over too much when turning over in the direction of the stopper structure 6.

[0040] Those skilled in the art will appreciate that the number of the second columnar structures 5 can be any other number, for example, the number of the second columnar structures 5 can be one, two, three, four, etc. Similarly, the number of the stop structures 6 is not limited to the four shown in the figure, and can be any other number, for example, one, two, three, etc.

[0041] Combine the following Figure 7 and Figure 8 The assembly process of the cover assembly of the present invention will be described in detail.

[0042] like Figure 7 As shown, the second columnar structure 5 is first aligned with the first columnar structure 3, and then the fixing plate 4 or the cover body 1 is rotated to align the strip opening 51 on the second columnar structure 5 with the connecting rib 2. Then the first columnar structure 3 is inserted into the second columnar structure 5 along the axial direction, and as the first columnar structure 3 moves, the connecting rib 2 enters the strip opening 51 and slides in the strip opening 51 until the first columnar structure 3 is inserted into the second columnar structure 5. Figure 1 and Figure 2 to the position shown.

[0043] like Figure 8 As shown, after the first columnar structure 3 is inserted into place, the cover body 1 can be rotated arbitrarily relative to the fixing plate 4.

[0044] like Figure 3 and Figure 4 As shown, a mounting position (not marked in the figure) for a torsion spring 8 is formed between the two first columnar structures 3 .

[0045] like Figure 5 and Figure 6 As shown, a mounting position (not shown) for a torsion spring 8 is formed in the middle of the six second columnar structures 5, and a clamping position (not shown) for clamping one end of the torsion spring 8 is also provided on the fixing plate 4. Figure 1 and Figure 2 As shown, in the mounted state, the two mounting locations are aligned with one another.

[0046] Continue reading Figure 1 and Figure 2 In the installed state, the pin 7 passes through the first columnar structure 3 and the torsion spring 8 respectively. On the one hand, it is used to fix the torsion spring 8 so that the torsion spring 8 can drive the cover body 1 to rotate in the direction away from the stop structure 6; on the other hand, it is used to strengthen the first columnar structure 3 to prevent the first columnar structure 3 from being deformed during the long-term use of the cover assembly.

[0047] like Figure 1 , 2 and Figure 8As shown, during the use of the cover assembly of the present invention, one end of the torsion spring 8 is clamped in the clamping position and abuts against the fixing plate 4, and the other end of the torsion spring 8 abuts against the cover body 1. Further, the two ends of the torsion spring 8 are respectively Figure 8 The fixing plate 4 and the left side of the cover body 1 are against each other. Preferably, the torsion spring 8 will only provide torque during the normal use of the cover assembly to make the fixing plate 4 and the cover body 1 flip to the left side. Figure 7 When the torsion spring 8 is in the position shown in FIG. 1 , it will only abut against one of the fixing plate 4 and the cover body 1 , so as to facilitate the insertion operation of the pin shaft 7 .

[0048] Based on the above description, those skilled in the art will understand that, in the present invention, a strip opening 51 is provided on the second columnar structure 5, so that the first columnar structure 3 can be directly inserted into the second columnar structure 5, and then the torsion spring 8 and the first columnar structure 3 are passed together through the pin shaft 7. During this process, there will be no misalignment between the holes, which facilitates the installation of the cover assembly and improves the tooling efficiency.

[0049] In another feasible embodiment of the present invention, different from the first embodiment, the pin shaft 7 is omitted, and the first columnar member 3 is configured to be able to penetrate the torsion spring 8. On this basis, those skilled in the art can also configure the first columnar member 3 to be a solid structure as needed.

[0050] In another feasible embodiment of the present invention, different from the above-mentioned first embodiment, those skilled in the art can replace the torsion spring 8 with a damper as needed, and the damper is used to hinder the rotation of the cover body 1 to prevent the cover body 1 from pinching the user when rotating too fast.

[0051] like Fig. 9 As shown, in the second embodiment of the present invention, unlike the first embodiment, the cover assembly does not have a connecting rib 2, the first columnar structure 3 and the second columnar structure 5 each have only one, and the length of the first columnar structure 3 is greater than the length of the second columnar structure 5, so as to allow the first columnar structure 3 to completely penetrate the second columnar structure 5. A bracket extends from both sides of one end of the cover body 1, and the two ends of the first columnar structure 3 are fixedly connected to one of the brackets. Further, the thickness of the bracket is less than the width of the strip opening 51, so that the bracket can enter the strip opening 51, so that the first columnar structure 3 can be inserted into the second columnar structure 5.

[0052] Although not shown in the figure, the present invention further provides a laundry processing drum, which includes a drum body and a cover assembly as described in any one of the above embodiments, wherein a fixing plate 4 is fixedly connected to the drum body, and a cover body 1 is used to close the drum mouth of the drum body. When the cover body 1 is turned over toward the inside of the drum body, the stop structure 6 can stop the connecting rib 2 to prevent the cover body 1 from turning over too much.

[0053] Although not shown in the figure, the present invention also provides a top-loading laundry processing device, which includes the cover assembly described in any of the above embodiments. The top-loading laundry processing device can be a top-loading drum washing machine, a top-loading drum dryer or a top-loading drum washer-dryer.
