When the laundry treating apparatus 20 is fixedly installed on the base assembly 10, the second connecting member 21 on the laundry treating apparatus 20 is aligned with the first connecting member 16 on the base assembly 10, so that the first folded portion 162 is aligned with the second folded portion 212, thereby connecting the first folded portion 162 and the second folded portion 212 together to achieve the fixed installation of the laundry treating apparatus 20 on the base assembly 10. In some embodiments, the second folded portion 212 and the second connecting portion 211 can be integrally formed, or can be fixedly connected together by welding, bonding, clamping, riveting, threaded connection, etc.

[0052] In some embodiments, mounting holes can be provided on the first folded portion 162 and the second folded portion 212. When the laundry treating apparatus 20 is installed on the base assembly 10, the mounting holes of the first folded portion 162 are aligned with the mounting holes of the second folded portion 212, thereby being fixedly connected together by bolts, rivets, etc., or being fixedly connected together by welding, bonding, etc., thereby achieving the fixed installation of the laundry treating apparatus 20 on the base assembly 10. In other embodiments, the first folded portion 162 and the second folded portion 212 can be positioned and connected together by clamping, inserting, etc. For example, one of the first folded portion 162 and the second folded portion 212 is formed with a socket, and the other is formed with a plug, or both of the first folded portion 162 and the second folded portion 212 are formed with a socket and a plug, and the plug is inserted into the socket to form the fixed connection of the first folded portion 162 and the second folded portion 212.

[0053] In some embodiments, the same number of mounting holes can be provided on the first folded portion 162 and the second folded portion 212. After the first folded portion 162 and the second folded portion 212 are aligned, the mounting holes are used to fixedly connect the first folded portion 162 and the second folded portion 212 together by bolts.

[0054] In some embodiments, among the two connecting holes on the first folded portion 162 and the second folded portion 212 which are in relative communication in position, one can be a round hole, and the other can be a waist round hole, so that the relative position of the first folded portion 162 and the second folded portion 212 can be adjusted when they are aligned and connected, thereby reducing the alignment requirement of the first folded portion 162 and the second folded portion 212 and improving the adaptability of the first connecting member 16 and the second connecting member 21.

[0055] In some embodiments, the connecting hole on the second folding part 212 can be a threaded hole, i.e. a screw is used to fix the first folding part 162 and the second folding part 212 together, which improves the convenience of connecting the first folding part 162 and the second folding part 212.

[0056] In some embodiments, as shown in FIG. 6, the second connecting piece 21 further comprises a positioning folding part 213, which is located at two edges of the bottom corner of the laundry treating apparatus 20, and the positioning folding part 213 is located at one end of the second connecting part 211 close to the periphery of the laundry treating apparatus 20, and extends along the thickness direction (the first direction Z) of the second connecting part 211. When the second connecting piece 21 is installed, the second folding part 212 is located at one of the edges, and the positioning folding part 213 abuts against the other edge, and the cooperation of the positioning folding part 213 and the second connecting part 211 at the supporting threaded hole forms double-point positioning, so as to position the second folding part 212, so that the second folding part 212 is arranged in parallel with the first folding part 162, thereby improving the connecting effect of the first folding part 162 and the second folding part 212.

[0057] In some embodiments, as shown in FIG. 7, the laundry treating apparatus 20 is generally rectangular in shape, and has four corner edges at the bottom. When supporting, the second connecting piece 21 is arranged at the four corner edges of the laundry treating apparatus 20, i.e. the four corner edges of the laundry treating apparatus 20. Correspondingly, the overall shape of the base assembly 10 can also be rectangular, so as to provide a larger accommodating space as much as possible without occupying additional space, thereby facilitating the accommodation of the cleaning apparatus 30. The top surface of the rectangular base assembly 10 also has four corner edges, i.e. four corner parts. When supporting the laundry treating apparatus 20, the first connecting piece 16 is arranged at the four corner parts respectively, so as to be connected one by one with the second connecting piece 21 at the four corner edges of the laundry treating apparatus 20, thereby improving the stability of supporting and connecting the laundry treating apparatus 20.

[0058] In some embodiments, the laundry treating apparatus 20 generally has four legs, i.e., four leg mounting holes are generally provided on the laundry treating apparatus 20. When the second connecting piece 21 is mounted on the laundry treating apparatus 20, the original four legs of the laundry treating apparatus 20 are removed, and the original leg mounting holes of the laundry treating apparatus 20 are used for mounting. For example, the leg mounting holes are leg threaded holes, the second connecting piece 21 is provided with through holes, and the second connecting piece 21 is fixed on the leg threaded holes by screws, so as to realize the mounting of the second connecting piece 21 on the laundry treating apparatus 20. By using the original structure of the laundry treating apparatus 20, the original leg mounting structure of the laundry treating apparatus 20 has high strength, the structure of the laundry treating apparatus 20 is not improved due to the mounting of the second connecting piece 21, the adaptability of the base assembly is improved, the production cost and maintenance cost are reduced, and the installation efficiency and reliability are improved. In other embodiments, the number of the first connecting pieces 16 and the second connecting pieces 21 can also be two, three, five or more. The plurality of first connecting pieces 16 and the plurality of second connecting pieces 21 can be uniformly distributed on the base assembly 10 and the laundry treating apparatus 20 respectively, so as to form stable support for the laundry treating apparatus 20.

The folding angle of the second folding part 212 relative to the second connecting part 211 can be 90°, i.e., the second folding part 212 is arranged parallel to the first folding part 162.

[0060] In some embodiments, as shown in FIG. 8, the second connecting piece 21 includes two second folding parts 212, which are located on both sides of the second connecting part 211 in the width direction (the second direction X) and are arranged in parallel. By providing two second folding parts 212, i.e., the second connecting piece 21 can be a symmetrical structure. The four second connecting pieces 21 provided on the four corner parts of the bottom of the laundry treating apparatus 20 can be completely the same, i.e., the four second connecting pieces 21 can not be divided into specific mounting corner parts when being mounted, thereby reducing the design and production cost of the second connecting piece 21 and improving the installation convenience of the second connecting piece 21.

[0061] In some embodiments, as shown in FIG. 8, two second folding portions 212 are formed with support folding portions 214 near one side of the base assembly 10. When the first connecting member 16 is connected with the second connecting member 21, the support folding portions 214 abut against the first connecting portion 161 of the first connecting member 16, thereby improving the support stability of the first connecting member 16 to the second connecting member 21. The support folding portions 214 on the two second folding portions 212 are folded towards each other, and the two support folding portions 214 are arranged in parallel with the first connecting portion 161, so that the support folding portions 214 and the first connecting portion 161 have sufficient contact area, thereby improving the stability of the support.

[0062] In some embodiments, as shown in FIG. 8, a plurality of avoiding portions 215 are formed between the two support folding portions 214, wherein some of the avoiding portions 215 are used to avoid the screws for fixing the second connecting portion 211, and the other avoiding portions are used to avoid the bolts for connecting the first connecting portion 161 with the top cover 12, so that the support folding portions 214 can be attached together with the first connecting portion 161. The avoiding portions 215 can be formed by cutting notches on the opposite sides of the two support folding portions 214, and the opposite notches increase the distance between the two support folding portions 214 to form the avoiding portions 215.

[0063] In some embodiments, the second connecting member 21 can be an integrated punching structure formed by punching, cutting and bending of a whole plate, thereby improving the structural strength of the second connecting member 21, improving the production effect, and reducing the production cost.
