[0041] Embodiments of the present disclosure provide a cleaning system. The cleaning system includes a base assembly, a first device and a second device. The base assembly forms a receiving space having an open end. The second device can be disposed on the base assembly, and the first device can be movably received in the receiving space of the base assembly below the second device. In some embodiments, such as Figure 1As shown, the first device may be a cleaning device 30, and the second device may be a clothing processing device 20. The base assembly 10 is formed with a receiving space having an open end. The cleaning device 30 can be accommodated in the receiving space of the base assembly 10 below the clothing processing device 20 by movement, that is, the base assembly 10 arranged below the clothing processing device 20 can serve as a base station of the cleaning device 30.

[0042] By placing the base stations of the clothing processing device 20 and the movable cleaning device 30 up and down, the base assembly 10 of the cleaning device 30 can occupy the same position as the clothing processing device 20, thereby avoiding the base assembly 10 of the cleaning device 30 from occupying additional area; at the same time, the base assembly 10 of the cleaning device 30 is arranged together with the clothing processing device 20, and the cleaning device 30 can share the same power interface with the clothing processing device 20 when charging in the base assembly 10, thereby avoiding the need to set up a dedicated line for the base assembly 10 of the cleaning device 30; when the cleaning device 30 is self-cleaning in the base assembly 10, the base assembly 10 can share the same water source and sewage outlet with the clothing processing device 20, thereby avoiding the need to set up a dedicated water source and sewage outlet for the base assembly 10 of the cleaning device 30, thereby greatly improving the ease of use of the cleaning device 30. Of course, the power supply of the cleaning device 30 when it is charging in the base assembly 10 and the power supply of the clothing processing device 20 can be divided into two independent power supplies, the water source of the cleaning device 30 when it is self-cleaning in the base assembly 10 and the water source of the clothing processing device 20 can also be two independent water sources, and the sewage outlet of the cleaning device 30 when it is self-cleaning in the base assembly 10 and the sewage outlet of the clothing processing device 20 can also be two independent sewage outlets.

[0043] In some embodiments, the clothing processing device 20 may be a drum washing machine, a pulsator washing machine, a clothing dryer or a washer-dryer, etc., and the cleaning device 30 may be a sweeping robot, a floor washing robot or a sweeping and mopping robot, etc., and the present disclosure does not limit this.

[0044] It is understandable that the present disclosure is not limited to only being able to set the clothing processing device 20 above the base assembly 10, and different devices or objects can be placed on the base as needed, and the present disclosure does not impose any limitation on this.

[0045] In some embodiments, Figures 1 to 4 As shown, a first connecting member 16 is provided on the top surface of the base assembly 10 for supporting the clothing processing device 20, and a second connecting member 21 is provided on the bottom of the clothing processing device 20. The connection between the base assembly 10 and the clothing processing device 20 is achieved by connecting the first connecting member 16 and the second connecting member 21.

[0046] In some embodiments, Figure 3As shown, the base includes a bottom plate 11, a top cover 12, a first side plate 13 and a second side plate 14. The first side plate 13 and the second side plate 14 are located between the bottom plate 11 and the top cover 12 along the first direction Z, and are connected to both sides of the bottom plate 11 in the width direction along the second direction X. The top cover 12, the first side plate 13, the second side plate 14 and the bottom plate 11 enclose a receiving space with an open end 15, and the open end 15 opens along the third direction Y. Wherein, the first direction Z is the thickness direction of the bottom plate 11 and the top cover 12, that is, the height direction of the first side plate 13 and the second side plate 14; the second direction X is the width direction of the bottom plate 11 and the top cover 12, that is, the thickness direction of the first side plate 13 and the second side plate 14; the third direction Y is the width direction of the first side plate 13 and the second side plate 14.

[0047] In some embodiments, as Figure 3 and Figure 4 shown, the first connecting member 16 includes a first connecting portion 161 and a first folding portion 162. The first connecting portion 161 is connected to the base assembly 10, and the first folding portion 162 is connected to the first connecting portion 161 and extends away from the top surface along the first direction Z relative to the first connecting portion 161; the first folding portion 162 is used to connect to the laundry treating device 20. In some embodiments, the first folding portion 162 and the first connecting portion 161 can be an integrally formed structure, or can be fixedly connected together by means of welding, bonding, clamping, riveting, threaded connection, etc.

[0048] In some embodiments, as Figure 4 shown, the first connecting portion 161 can be detachably connected to the top cover 12 by bolts. Through holes can be provided at the corner portions of the top cover 12, and corresponding through holes are provided on the first connecting portion 161, so as to fixedly connect the first connecting member 16 and the top cover 12 by bolts. The number of through holes is greater than two, so as to form a unique fixed position of the first connecting member 16 on the top cover 12 through multi-point fixing, which is convenient for the assembly of the first connecting member 16 on the top cover 12.

[0049] In some embodiments, as Figure 4 shown, the first connecting member 16 includes one first connecting portion 161 and two first folding portions 162. Since the first connecting member 16 is arranged at the corner portion of the top cover 12, the shape of the first connecting portion 161 can be triangular to increase the contact area between the first connecting portion 161 and the top cover 12 and improve the connection stability between the first connecting member 16 and the top cover 12. The two first folding portions 162 are located at the two edges of the corner portion, and the folding angles of the two first folding portions 162 relative to the first connecting portion 161 can be 90°, that is, the first folding portions 162 are perpendicular to the top cover 12.

[0050] In some embodiments, as Figure 4As shown, the first folding portion 162 is away from the edge of the top cover 12, and a flanging 163 facing the side periphery is formed. By making the first folding portion 162 away from the edge of the top cover 12 and forming a flanging 163 facing the side periphery, a guiding structure is formed for the second folding portion 212 of the second connecting member 21 to extend into the inner side of the first folding portion 162, preventing the second folding portion 212 of the second connecting member 21 from extending to the outer side of the first folding portion 162 when installed on the first connecting member 16, and improving the installation convenience.

[0051] In some embodiments, the first connecting member 16 may be a symmetric structure, such that the first connecting members 16 provided at the four corner portions are exactly the same, that is, when installing the four first connecting members 16, it is not necessary to distinguish the specific corner portion for installation, reducing the design and production cost of the first connecting member 16 and improving the installation convenience of the first connecting member 16. Of course, the first connecting members 16 provided at the four corner portions may not be the same. For example, only one folding portion may be provided for the first connecting member 16, and the folding portion of the two first folding portions 162 that is not connected to the second folding portion 212 can be removed.

[0052] In some embodiments, the first connecting member 16 may be an integrally blanked structure formed by stamping, cutting, and bending a whole plate, improving the structural strength of the first connecting member 16, enhancing the production effect, and reducing the production cost.

[0053] In some embodiments, as Figures 5 to 8 shown, the second connecting member 21 includes a second connecting portion 211 and a second folding portion 212. The second connecting portion 211 is connected to the bottom of the laundry treatment device 20, and the second folding portion 212 is connected to the second connecting portion 211 and extends along the first direction Z away from the bottom of the laundry treatment device 20 relative to the second connecting portion 211; the second folding portion 212 is used to connect with the first folding portion 162. When fixedly installing the laundry treatment device 20 on the base assembly 10, align the first connecting member 16 on the laundry treatment device 20 with the first connecting member 16 on the base assembly 10, so that the first folding portion 162 is aligned with the second folding portion 212, and then connect the first folding portion 162 and the second folding portion 212 together to realize the fixed installation of the laundry treatment device 20 on the base assembly 10. In some embodiments, the second folding portion 212 and the second connecting portion 211 may be an integrally formed structure, or may be fixedly connected together by means such as welding, bonding, clamping, riveting, and threaded connection.

[0054] In some embodiments, mounting holes may be provided on the first folding portion 162 and the second folding portion 212. When the laundry treating apparatus 20 is mounted on the base assembly 10, the mounting holes of the first folding portion 162 are aligned with those of the second folding portion 212, and then they are fixedly connected by connectors such as bolts and rivets, or the first folding portion 162 and the second folding portion 212 are fixedly connected together by welding, bonding or the like, so as to realize the fixed mounting of the laundry treating apparatus 20 on the base assembly 10. In other embodiments, the first folding portion 162 and the second folding portion 212 may be positioned and connected together by means of snap connection, plug connection or the like. For example, a jack is formed on one of the first folding portion 162 and the second folding portion 212, and a tongue is formed on the other, or both the first folding portion 162 and the second folding portion 212 are formed with jacks and tongues, and the first folding portion 162 and the second folding portion 212 are fixedly connected by inserting the tongue into the jack.

[0055] In some embodiments, the first folding portion 162 and the second folding portion 212 may be provided with the same number of mounting holes. After the first folding portion 162 and the second folding portion 212 are aligned, the first folding portion 162 and the second folding portion 212 are fixedly connected together by bolts using the mounting holes.

[0056] In some embodiments, of the two connecting holes that are in relative communication positions on the first folding portion 162 and the second folding portion 212, one may be a round hole and the other may be an oval hole, so that the relative positions of the first folding portion 162 and the second folding portion 212 can be adjusted when they are aligned and connected, thereby reducing the alignment requirements for the first folding portion 162 and the second folding portion 212 and improving the adaptability of the first connecting member 16 and the second connecting member 21.

[0057] In some embodiments, the connecting hole on the second folding portion 212 may be a threaded hole, that is, the first folding portion 162 and the second folding portion 212 can be fixed together by using screws, which improves the convenience of connecting the first folding portion 162 and the second folding portion 212.

[0058] In some embodiments, such as Figure 6As shown, the second connecting member 21 further includes a positioning folding portion 213. The positioning folding portion 213 and the second folding portion 212 are located at two edges of the bottom corner of the laundry treatment device 20. The positioning folding portion 213 is located at one end of the second connecting portion 211 close to the periphery of the laundry treatment device 20, and the positioning folding portion 213 extends along the thickness direction (the first direction Z) of the second connecting portion 211. When installing the second connecting member 21, the second folding portion 212 is located at one of the edges, the positioning folding portion 213 abuts against the other folded edge, and the cooperation between the positioning folding portion 213 and the second connecting portion 211 at the support foot threaded hole forms double-point positioning, so as to realize the positioning of the position of the second folding portion 212, make the second folding portion 212 arranged in parallel with the first folding portion 162, and thus improve the connection effect between the first folding portion 162 and the second folding portion 212.

[0059] In some embodiments, as Figure 7 shown, the laundry treatment device 20 is generally rectangular as a whole, and its bottom has four corners. When supporting, it is supported at the four corner positions, that is, the second connecting members 21 are arranged at the four corner positions of the laundry treatment device 20. Correspondingly, the overall shape of the base assembly 10 can also be rectangular, so as to provide a relatively large accommodation space as much as possible without occupying extra space, which is convenient for the accommodation of the cleaning device 30. The top surface of the rectangular base assembly 10 also has four corners, that is, four corner portions. When supporting the laundry treatment device 20, the first connecting members 16 are respectively arranged at the four corner portions thereof, so as to be connected in one-to-one correspondence with the second connecting members 21 at the four corner positions of the laundry treatment device 20, improving the stability of the support and the connection of the laundry treatment device 20.

[0060] In some embodiments, since the laundry treatment device 20 usually has four feet, that is, four foot mounting holes are usually provided on the laundry treatment device 20. When installing the second connecting member 21 on the laundry treatment device 20, the original four feet at the bottom of the laundry treatment device 20 are removed, and then the original foot mounting holes of the laundry treatment device 20 can be used for installation. For example, the foot mounting holes are foot threaded holes, and through holes are provided on the second connecting member 21. The second connecting member 21 is fastened to the foot threaded holes by screws, thereby realizing the installation of the second connecting member 21 on the laundry treatment device 20. By using the original structure of the laundry treatment device 20, the original foot mounting structure of the laundry treatment device 20 has relatively high strength, avoiding the need to improve the structure of the laundry treatment device 20 due to the installation of the second connecting member 21, improving the adaptability of the base assembly, reducing the production cost and maintenance cost, and improving the installation efficiency and reliability. In other embodiments, the number of the first connecting members 16 and the second connecting members 21 may also be two, three, five or more. The plurality of first connecting members 16 and the second connecting members 21 may be evenly distributed on the base assembly 10 and the laundry treatment device 20 respectively to form a stable support for the laundry treatment device 20. The present disclosure does not limit this.

[0061] In some embodiments, as Figure 8 shown, the second folding portion 212 is arranged parallel to the edge of the laundry treatment device 20, so that the second folding portion 212 is arranged parallel to one of the two first folding portions 162 on the corresponding first connecting member 16, thereby improving the connection stability between the second folding portion 212 and the first folding portion 162. The folding angle of the second folding portion 212 relative to the second connecting portion 211 may be 90°, that is, the second folding portion 212 is arranged parallel to the first folding portion 162.

[0062] In some embodiments, as Figure 8 shown, the second connecting member 21 includes two second folding portions 212, and the second folding portions 212 are located on both sides in the width direction (second direction X) of the second connecting portion 211, and the two second folding portions 212 are arranged in parallel. By providing two second folding portions 212, that is, the second connecting member 21 can be a symmetric structure; the second connecting members 21 provided at the four corner portions at the bottom of the laundry treatment device 20 can be exactly the same, that is, when installing the four second connecting members 21, the specific corner portions for installation do not need to be distinguished, reducing the design and production cost of the second connecting member 21 and improving the installation convenience of the second connecting member 21.

[0063] In some embodiments, as Figure 8As shown in the figure, on the side of the two second folding parts 212 close to the base assembly 10, there are formed supporting folding parts 214. After the first connecting member 16 is connected to the second connecting member 21, the supporting folding part 214 abuts against the first connecting part 161 of the first connecting member 16, improving the supporting stability of the first connecting member 16 to the second connecting member 21. The supporting folding parts 214 on the two second folding parts 212 are formed by folding towards each other. The two supporting folding parts 214 are arranged parallel to the first connecting part 161, so that there is enough contact area between the supporting folding part 214 and the first connecting part 161, improving the supporting stability.

[0064] In some embodiments, as Figure 8 shown in the figure, there are formed a plurality of avoiding parts 215 between the two supporting folding parts 214. Some of the avoiding parts 215 are used to avoid the screws for fixing the second connecting part 211, and the other part of the avoiding parts are used to avoid the bolts connecting the first connecting part 161 and the top cover 12, so that the supporting folding part 214 can be attached to the first connecting part 161. Among them, the avoiding part 215 can be formed by setting notches on the opposite side edges of the two supporting folding parts 214. The opposite two notches increase the distance between the two supporting folding parts 214 to form the avoiding part 215.

[0065] In some embodiments, the second connecting member 21 can be an integrally blanked structure formed by stamping, cutting and bending a whole plate, which improves the structural strength of the second connecting member 21, improves the production effect and reduces the production cost.

[0066] Those skilled in the art will readily conceive of other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure, which follow the general principles of the present disclosure and include known common knowledge or conventional technical means in the technical field not disclosed in the present disclosure.
