[0032] like Figures 1 to 3 As shown, the present application discloses a decorative cover assembly structure comprising a material box cover 1, a cover assembly 2, and a decorative cover 3. The material box cover 1 is fixedly connected to the material box by means of structures such as bolts or snaps, the cover assembly 2 is fixedly connected to the material box cover 1 by means of structures such as bolts or snaps, and the decorative cover 3 is connected to the cover assembly 2 by means of snaps. Specifically, the cover assembly 2 comprises a rear cover 21 and a front cover 22. The rear cover 21 is fixedly connected to the material box cover 1 by means of structures such as bolts or snaps, and the front cover 22 is fixedly connected to the rear cover 21 by means of bolts and snaps. The decorative cover 3 has curved edges 31 on both sides. The decorative cover 3 is simultaneously engaged with the rear cover 21 and the front cover 22 by means of the curved edges 31, and the engaging positions of the curved edges 31 with the rear cover 21 and the front cover 22 are staggered. The decorative cover 3 of the decorative cover assembly structure is staggered and interlaced with the cover assembly 2 by means of the curved edges 31, making the assembly operation simple and quick, and the connection more stable, with lower overall design and production costs.

[0033] For details, see Figures 4 to 6 The sides of the rear cover 21 are each provided with an extension edge 210. The extension edges 210 on the front and rear sides of the rear cover 21 extend from the top of the side toward the front cover 22. The extension edges 210 on the left and right sides of the rear cover 21 extend horizontally from the bottom of the side. The sides of the rear cover 21 are provided with assembly buckles 211 arranged at intervals. The extension edges 210 on the left and right sides of the rear cover 21 are provided with a plurality of positioning buckles 212, which are arranged alternately with the assembly buckles 211. The bent edge 31 of the decorative cover 3 engages with the positioning buckles 212.

[0034] The side of the front cover 22 has several downwardly extending assembly parts 221. Each assembly part 221 has assembly holes 222. The assembly parts 221 engage with the assembly buckles 211 through the assembly holes 222, thereby securing the front cover 22 to the rear cover 21. Adjacent assembly parts 221 are spaced apart, and the positioning buckles 212 are vertically aligned with the spaced assembly parts 221. The outer bottom ends of the assembly parts 221 have reverse buckles 2212 that engage with the bent edge 31. At least one assembly buckle 211 has recessed grooves 2211 at both ends of its bottom end to facilitate viewing during installation. Furthermore, the spaced apart parts have recessed portions 223 that extend into the interior of the front cover 22. The positioning buckles 212 are vertically aligned with the recessed portions 223.

[0035] See also Figure 7 and Figure 8 The two bent edges 31 of the decorative cover 3 are both bent downward. The bottom ends of the bent edges 31 bend inwardly of the decorative cover 3 to form a snapping edge 310, which snaps into place with the reverse buckle 2212. The snapping edge 310 has a number of positioning blocks 32 extending inwardly of the decorative cover 3. The positioning blocks 32 have positioning holes 321 that align and snap into place with the positioning buckles 212. The bent edges 31 snap into place with the rear cover 21 via the positioning buckles 212, and the bent edges 31 snap into place with the front cover 22 via the reverse buckle 2212. This allows the decorative cover 3 to be simultaneously connected to both the rear cover 21 and the front cover 22, ensuring a secure connection and quick and easy installation.

[0036] See also Figure 9 When assembling the decorative cover assembly structure, the front cover 22 and the rear cover 21 are first assembled together. The assembly part 221 of the front cover 22 is engaged with the assembly buckle 211 through the assembly through-hole 222. The front cover 22 and the rear cover 21 can then be reinforced by bolting. After the front cover 22 and the rear cover 21 are assembled, the reverse buckle 2212 is located on the outside, and the positioning buckle 212 is vertically aligned with the recessed portion 223. The decorative cover 3 is then installed, and the positioning block 32 is aligned with the recessed portion 223 and pressed, so that the engaging edge 310 is engaged with the reverse buckle 2212, and the positioning block 32 is engaged with the positioning buckle 212, completing the assembly operation of the decorative cover assembly structure. It is worth noting that the width of the positioning block 32 needs to be smaller than the width of the recessed portion 223.

[0037] See also Figure 10 and Figure 11After the front cover 22 and the back cover 21 are assembled, the distance a between the middle of the assembly part 221 and the back cover 21 needs to be as small as possible to strengthen the connection strength and prevent the decorative cover 3 from deforming. Preferably, the middle of the assembly part 221 is in contact with the back cover 21. The distance between the bottom end of the assembly part 221 and the back cover 21 is b, and the effective assembly distance of the reverse buckle 2212 is c, where b>c, to ensure that when the reverse buckle 2212 is deformed, the assembly part 221 can be effectively disengaged, ensuring the convenience of the assembly operation. The height of the positioning buckle 212 is H, and the effective assembly height of the reverse buckle 2212 is h, where H>h. Considering the thickness of the snap edge 310, H>h is required to ensure the stability of the assembly.

[0038] See also Figure 12 and Figure 13 The distance between the assembly part 221 and the bent edge 31 is Q, and the width of the snap edge 310 is q, where Q>q, to ​​facilitate installation of the decorative cover 3. The front cover 22 is bounded by the top of the reverse buckle 2212, with the upper portion being region D and the lower portion being region E. The snap edge 310 of the decorative cover 3 is unimpeded when moving in region D. When it reaches region E, it contacts the reverse buckle 2212, squeezing the assembly part 221 inward. Continued pressure on the decorative cover 3 pushes the snap edge 310 to the bottom of the reverse buckle 2212, achieving engagement between the snap edge 310 and the reverse buckle 2212. Simultaneously, the positioning block 32 moves downward with the snap edge 310, engaging the positioning buckle 212 through the positioning hole 321.

[0039] The present application also provides an electrical appliance that adopts the decorative cover assembly structure, and the electrical appliance can be a washing machine, a dryer, a washer-dryer, etc.
