[0052] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this disclosure, "a plurality of" means two or more, unless otherwise expressly specified.

[0053] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0057] The way different home appliances are combined in related technologies will increase the difficulty of disassembling, assembling and repairing them to some extent.

[0058] Taking home cleaning appliances as an example, with continuous technological advancements, home appliances with different cleaning functions are constantly emerging, such as robot vacuums with sweeping capabilities and robot mops that can sweep and mop simultaneously. However, the placement of these appliances requires space in the user's living area, and placing multiple appliances individually can make the home environment feel cramped. To reduce the space occupied by various appliances and improve the utilization of the home environment, related technologies are gradually starting to combine cleaning devices with different functions. For example, washing machines and dryers can be stacked, or space can be reserved at the bottom of washing machines (or dryers), air purifiers, etc., to accommodate cleaning base stations that work with floor cleaning units (such as robot vacuums and robot mops). However, combining two types of appliances together increases the difficulty of maintenance.

[0059] To address the aforementioned issues, this disclosure provides a frame 10, a cleaning device 100, and a cleaning system 1000. The frame 10 integrates clothing processing equipment (including at least one of a washing machine and a dryer) and a cleaning base station for cooperating with a floor cleaning host 200 into the same cleaning device 100. This not only helps reduce the space occupied by the cleaning device 100 in the home but also effectively improves the overall stability, reliability, and safety of the cleaning device 100.

[0060] Figure 1 is a partial structural schematic diagram of the cleaning system 1000 provided in an embodiment of the present disclosure, Figure 2 is a partial structural schematic diagram of the cleaning equipment 100 provided in an embodiment of the present disclosure, and Figure 3 is a schematic diagram of the internal structure of the cleaning equipment 100 provided in an embodiment of the present disclosure.

[0061] For ease of description, the embodiments of this disclosure define the height direction of the cleaning system 1000 at its upper and lower ends as the first direction (i.e., the X-axis direction), the direction of the cleaning system 1000 on its front and rear sides as the second direction (i.e., the Y-axis direction), and the direction of the cleaning system 1000 on its left and right sides as the third direction (i.e., the Z-axis direction), wherein the X-axis direction, the Y-axis direction, and the Z-axis direction are mutually perpendicular.

[0062] Please refer to Figures 1 and 2. This disclosure provides a cleaning system 1000 and a cleaning device 100. The cleaning system 1000 includes a cleaning device 100 and a floor cleaning unit 200 that cooperates with the cleaning device 100. The bottom of the cleaning device 100 has a receiving space 301, and a ramp 50 is installed in the receiving space 301. The floor cleaning unit 200 can enter and exit relative to the receiving space 301 through the ramp 50 to cooperate with the cleaning device 100. Referring to Figure 2, the cleaning device 100 has a box-like structure. The drum 20 for handling clothes and the base station module 30 for cooperating with the floor cleaning host 200 are both located within the box-like structure of the cleaning device 100. The drum 20 can be a washing drum for washing clothes, a drying drum for drying clothes, or a drum that combines washing and drying functions. The base station module 30 has a receiving space 301 for housing the floor cleaning host 200. The floor cleaning host 200 can cooperate with the base station module 30 and be housed within the receiving space 301, or move in and out of the receiving space 301. This embodiment does not limit the clothes handling function of the cleaning device 100; that is, the clothes handling function of the cleaning device 100 can have washing and / or drying functions. In other words, the cleaning device 100 provided in this embodiment can be a washing machine with a base station module 30, a dryer with a base station module 30, or a washer-dryer combo with a base station module 30, etc.

[0063] It should be noted that the overall size of the cleaning device 100 provided in this embodiment is basically the same as that of existing conventional clothing processing devices, especially its size in the first direction. In other words, the cleaning device 100 provided in this embodiment can achieve the effect of simultaneously arranging the cylinder 20 and the base station module 30 inside the box without increasing or significantly increasing its height. This saves the space occupied by the cleaning device 100 in the user's home while effectively improving the overall stability, reliability and safety of the cleaning device 100.

[0064] It should be noted that the enclosure mentioned in this embodiment includes decorative panels such as the top plate, left and right side plates, and back plate constituting the cleaning equipment 100. These decorative panels can be either an integral structure or a separate structure. When the decorative panels are separate, they can be fixedly connected by bolts or riveting to form a space for accommodating the cylinder 20 and the base station module 30, while also providing some protection for the cylinder 20 and the base station module 30.

[0065] For the sake of overall strength and rigidity of the cleaning equipment 100, the top plate, left and right side plates, and back plate constituting the housing can be made of galvanized steel sheet and / or color steel sheet. For example, color steel sheet with a thickness of not less than 0.7 mm can be used to make the top plate and left and right side plates, and galvanized steel sheet with a thickness of not less than 0.5 mm can be used to make the back plate. In some embodiments, the thickness of the color steel sheet does not exceed 1.2 mm, and the thickness of the galvanized steel sheet does not exceed 1.5 mm.

[0066] In this embodiment of the disclosure, the thickness of the selected color steel plate is 0.7 mm, and the thickness of the selected galvanized steel plate is 1.0 mm.

[0067] The cleaning device 100 has a front door panel 40 on its front side in the second direction, and the front door panel 40 has a loading / unloading port 401 that cooperates with the cylinder 20. Clothes can be put into or taken out of the cylinder 20 through the loading / unloading port 401; the cleaning device 100 also includes a first door (not shown in the figure), which cooperates with the front door panel 40 and opens or closes the loading / unloading port 401 by moving relative to the front door panel 40. The base station module 30 is located below the cylinder 20 and forms a receiving space 301 that can be exposed relative to the front door panel 40.

[0068] In some embodiments, the cleaning device 100 further includes a second door (not shown) that cooperates with the base station module 30. The second door can expose or obscure the base station module 30 located within the cleaning device 100 by moving relative to the base station module 30. When the second door moves to expose the base station module 30, the ground cleaning host 200 can easily drive in or out relative to the base station module 30. When the second door moves to obscure the base station module 30, the aesthetics of the cleaning device 100 can be effectively improved. To ensure the overall aesthetics of the cleaning device 100 when the second door moves to expose the base station module 30, the cleaning device 100 can also include decorative elements (not shown) that cooperate with the second door and the base station module 30. These decorative elements can be located on both sides of the base station module 30 in a third-order direction to obscure the portion of the cleaning device 100 located on both sides of the base station module 30. In some embodiments, the decorative elements can be made of metal material using sheet metal processing or made of plastic material.

[0069] In some embodiments, the base station module 30 in the cleaning equipment 100 can be used in conjunction with the ground cleaning host 200, meaning that the base station module 30 can serve as a docking station for the ground cleaning host 200. It should be noted that the ground cleaning host 200 needs to drive into or out of the base station module 30 via the ramp 50 so that the base station module 30 can fulfill its docking station function.

[0070] When the ground cleaning host 200 starts working, it can depart from the base station module 30 and execute the corresponding cleaning task. When the ground cleaning host 200 completes the cleaning task or when other situations require terminating the cleaning task, it can return to the base station module 30 to perform at least one or more tasks such as charging, water replenishment, cleaning, and dust collection. The base station module 30 also has a dust collection chamber and a corresponding dust chamber door, and a dust collection bag is detachably installed inside the dust collection chamber.

[0071] It is understood that the internal water supply system of the base station module 30 in the cleaning equipment 100 provided in this embodiment can be directly connected to an external pipe or indirectly connected to an external pipe; similarly, the internal drainage pipe of the base station module 30 in the cleaning equipment 100 can be directly connected to a sewer or mixed with the sewage discharged from the cylinder 20 and discharged into the sewer through the same drainage pipe.

[0072] The base station module 30 is located below the cylinder 20 in the first direction. Since the base station module 30 needs to cooperate with the ground cleaning host 200, and the ground cleaning host 200 needs to move out from the base station module 30 and quickly move to the area to be cleaned during cleaning, setting the base station module 30 below the cylinder 20 can facilitate the normal use of the ground cleaning host 200.

[0073] Please refer to Figure 3. A frame 10 is installed inside the cleaning equipment 100, enclosing a space for accommodating the cylinder 20 and the base station module 30. As a load-bearing component, the frame 10 has good vertical load-bearing capacity and resistance to horizontal tilting. Therefore, it can effectively support the weight of the cylinder 20 and its load, the base station module 30, and the ground cleaning host 200 and its load, thus providing good support for the cylinder 20, base station module 30, and ground cleaning host 200. This effectively improves the structural stability and reliability of the cleaning equipment 100 while integrating the cylinder 20 and base station module 30 within it. Furthermore, the support of the frame 10 effectively reduces the structural strength requirements of the plates constituting the housing, thereby reducing the manufacturing difficulty and cost of the housing and facilitating more sophisticated process designs for the cleaning equipment 100 housing.

[0074] In some embodiments, a gap exists between the cylinder 20 and the base station module 30 in the first direction to avoid mutual interference between the cylinder 20 and the base station module 30 during operation. For example, this prevents interference between the cylinder 20 and the base station module 30 due to rotational vibration during operation, while ensuring that the ground cleaning host 200 is not affected during charging or self-cleaning processes in cooperation with the base station module 30 when the cylinder 20 is operating.

[0075] In some embodiments, a vibration damper 60 is also provided inside the cleaning device 100. Referring to Figure 3, one end of the vibration damper 60 can be mounted on the frame 10, and the other end can be mounted on the side of the cylinder 20 facing the base station module 30 to provide an upward supporting force to the cylinder 20, ensuring that the cylinder 20 will not interfere with the base station module 30 located below it due to insufficient supporting force.

[0076] Figure 4 is a schematic diagram of the overall structure of the frame 10 provided in the embodiment of this disclosure. Figure 5 is a schematic diagram of the structure of the base 1 in the frame 10 provided in the embodiment of this disclosure. Figure 6 is a schematic diagram of the assembly of the base 1 and part of the base station module 30 in the frame 10 provided in the embodiment of this disclosure. Figure 7 is a top view of the assembly of the base 1 and part of the quick-turn module in the frame 10 provided in the embodiment of this disclosure. Figure 8 is a schematic diagram of the cross-sectional structure along direction AA in Figure 7. Figure 9 is an enlarged view of the structure of area B in Figure 8. Figure 10 is a schematic diagram of the assembly of the base 1 and part of the cylinder 20 in the frame 10 provided in the embodiment of this disclosure.

[0077] Referring to Figure 4, the frame 10 forms the load-bearing structure of the cleaning equipment 100. The frame 10 includes a fixedly connected base 1 and longitudinal beam 2, as well as a foot 3, structural reinforcement 4, and top reinforcement 5. The lower end of the longitudinal beam 2 is fixedly connected to the base 1 in the first direction, and its upper end is fixedly connected to the top reinforcement 5. The structural reinforcement 4 is fixedly connected to the middle of the longitudinal beam 2 in the first direction. The fixed connection of the base 1, longitudinal beam 2, structural reinforcement 4, and top reinforcement 5 forms a robust support frame. The foot 3 is installed below the base 1 in the first direction to support the support frame. The frame 10 contains an accommodating space for simultaneously accommodating the cylindrical body 20 and the base station module 30. Taking the orientation shown in Figure 4 as an example, the cylindrical body 20 is located above the base station module 30.

[0078] It should be noted that the cylinder 20 can be located directly above the base station module 30 or diagonally above the base station module 30. The structural reinforcement 4 is connected to the middle of the longitudinal beam 2. Here, the middle refers to any position between the two ends of the longitudinal beam 2 in the first direction X, which can be slightly above or below the midpoint of the midpoint. In this embodiment, the connection position between the structural reinforcement 4 and the longitudinal beam 2 can be slightly below the midpoint of the longitudinal beam 2 and close to the base 1.

[0079] When the frame 10 is placed on the mounting surface, the base 1 can transfer the force to the feet 3 so that the feet 3 can bear the weight of the entire machine. At the same time, the feet 3 can also be used to level the frame 10 when the mounting surface is not level.

[0080] Referring to Figure 4, the frame 10 has eight vertices and includes four spaced-apart longitudinal beams 2 of the same size in the first direction. These four beams define a quadrilateral structure (i.e., a rectangular structure) in a plane perpendicular to the first direction. The four beams 2 are located at the vertices of the quadrilateral. Any one of the beams 2 is fixedly connected to the base 1 below in the first direction and to the top reinforcing member 5 above in the first direction, ultimately forming a rectangular structure. The feet 3 are arranged opposite to the longitudinal beams 2 and installed below the base 1, specifically at the four top feet of the base 1 near the bottom of the mounting surface. For the frame 10 provided in this embodiment, the frame 10 can contact the mounting surface through the feet 3 to transmit the load provided by the frame 10 and the cleaning device 100.

[0081] The frame 10 has a top surface and a bottom surface in a first direction, wherein the top surface is the end of the frame 10 away from the base 3 in the first direction, and the side surface is the outer periphery of the frame 10 in the first direction. For ease of description, the side surfaces of the frame 10 are defined as the front side, rear side, left side, and right side, wherein the two sides of the frame 10 in the second direction are the front side and rear side, respectively, and the two sides in the third direction are the left side and right side, respectively.

[0082] Referring to Figure 4, in this embodiment, the structural reinforcement 4 includes a front reinforcement 41 and lateral reinforcements 42. The front reinforcement 41 is fixedly connected to two longitudinal beams 2 located on the front side of the frame 10 in the second direction. There are two lateral reinforcements 42, each fixedly connected to two longitudinal beams 2 located on opposite sides of the frame 10 in the third direction. The lateral reinforcements 42 are located on the side of the front reinforcement 41 facing away from the base 1 in the first direction. The top reinforcement 5 includes a first reinforcing crossbeam 51 and a second reinforcing crossbeam 52, wherein there are two first reinforcing crossbeams 51. Two first reinforcing crossbeams 51 are located on the side of the corresponding lateral reinforcing member 42 away from the base 1 and are fixedly connected to the top of the longitudinal beam 2 in the first direction. The second reinforcing crossbeam 52 includes a front reinforcing crossbeam 521 located on the front side of the frame 10 in the second direction and a rear reinforcing crossbeam 522 located on the rear side of the frame 10 in the second direction. The front reinforcing crossbeam 521 is fixedly connected to the two longitudinal beams 2 located on the front side of the frame 10 through the two first reinforcing crossbeams 51, and the rear reinforcing crossbeam 522 is fixedly connected to the two longitudinal beams 2 located on the rear side of the frame 10 through the two first reinforcing crossbeams 51.

[0083] The longitudinal beam 2 has a strong load-bearing capacity and can be used to support and transfer loads. In the frame 10 provided in this embodiment, the longitudinal beam 2 can be fixedly connected to at least one of the base 1, structural reinforcement 4 and top reinforcement 5 by any of the connection methods such as bolt connection, welding and riveting, so as to form a stable spatial structure.

[0084] In some embodiments, the longitudinal beam 2 is fixedly connected to the flange 12 by fasteners. Fastening holes for fasteners to pass through are provided at corresponding positions on the longitudinal beam 2 and the flange 12.

[0085] The fastener can be a threaded connection structure such as a bolt or screw, or a structure such as a rivet.

[0086] To reduce the difficulty of connecting the longitudinal beam 2 and the base 1, and to further improve the connection efficiency between the longitudinal beam 2 and the base 1, in some embodiments, one of the flange 12 and the longitudinal beam 2 can be pre-connected via structures such as hooks, hanging holes, positioning protrusions, and positioning holes, and then fixedly connected via structures such as bolts and fasteners. Similarly, the structural reinforcement 4 and the top reinforcement 5 can also be fixedly connected to the longitudinal beam 2 via similar connection methods.

[0087] It should be noted that the top reinforcement 5 includes a first reinforcing crossbeam 51 and a second reinforcing crossbeam 52, wherein the first reinforcing crossbeam 51 has a hanging hole 5101 for installing the suspension assembly. One end of the suspension assembly is fixedly connected to the first reinforcing crossbeam 51 through the hanging hole 5101, and the other end is connected to the cylinder 20 located inside the frame 10.

[0088] In some embodiments, the suspension assembly may be a suspension spring. The left and right sides of the cylinder 20 are connected to the first reinforcing crossbeam 51 by suspension springs to provide better installation stability for the cylinder 20.

[0089] Please refer to Figure 5. The base 1 has foot mounting holes 114 at all four corners. The feet 3 can be mounted on the base 1 through the foot mounting holes 114 to support the base 1.

[0090] When the foot 3 contacts the mounting surface, the bottom surface of the base 1 is higher than the mounting surface, so that the base 1 can maintain a certain gap with the mounting surface through the foot 3.

[0091] In some embodiments, the base foot 3 is an adjustable base foot 3. By adjusting the length of the base foot 3 relative to the extension portion of the base 1 in the first direction, the height of the bottom surface of the base 1 can be further adjusted to ensure that there is a gap between the base 1 and the mounting surface; at the same time, the base foot 3 can also adjust the height of the four top corners of the frame 10 so that the frame 10 can better adapt to the not completely level mounting surface, thereby achieving precise adjustment of the levelness of the frame 10.

[0092] Please refer to Figure 5. The base 3 is movably connected to the base 1 through the base mounting hole 114 opened on the base 1, and can move relative to the base 1 in the first direction to adjust the height of the frame 10 at the four corner positions.

[0093] In some embodiments, the base 3 includes a screw, and the base mounting hole 114 is a threaded hole. The base 3 can be threadedly connected to the base mounting hole 114 by the screw, and the height of the four corners of the frame 10 can be easily adjusted by rotating the base 3 so that the four corners are on the same plane, and the bottom surface of the base 1 does not directly contact the mounting surface and there is a gap between them.

[0094] In some embodiments, the base 1 is entirely a sheet metal part, including a fixedly connected base plate 11 and a flange 12. The flange 12 is located above the base plate 11 and is formed by folding a portion of the circumferential side edge of the base plate 11 towards the same side along a first direction. The longitudinal beam 2 can be fixedly connected to the base 1 through the flange 12. Referring to Figures 4 and 5, one end of the flange 12 is connected to a portion of the circumferential side edge of the base plate 11, and the other end is folded upwards towards the base plate 11 along the first direction.

[0095] In some embodiments, the base 1 can be integrally formed by stamping process to ensure the overall structural strength of the base 1.

[0096] In some embodiments, the base 1 is divided into two regions with different upper surface heights in a first direction, namely a first region 1a and a second region 1b. In the first direction, the height of the first region 1a is higher than the height of the second region 1b. Referring to Figures 4 and 5, the second region 1b is recessed relative to the first region 1a in the first direction. The base 1 can contact the base station module 30 through the first region 1a. At this time, the base station module 30 is located on the upper surface of the base 1 and in contact with the first region 1a. There is a certain gap between the second region 1b and the base station module 30 in the first direction, as shown in Figure 6. This gap can prevent the base station module 30 from directly contacting and squeezing the second region 1b, so as to ensure that the second region 1b will not be deformed due to the squeezing of the base station module 30, which helps to better maintain the shape of the second region 1b. In addition, the cleaning device 100 will generate a certain amount of condensate when it is working. The above-mentioned gap also helps to separate the base station module 30 from the condensate formed in the cleaning device 100 and located in the second region 1b, which can further improve the electrical safety of the base station module 30.

[0097] It should be noted that the gap mentioned above is formed between the bottom surface of the second region 1b and the mounting surface.

[0098] In some embodiments, the base 1 includes a fixedly connected base plate 11 and a flange 12, wherein the flange 12 mates with the base plate 11 at one end of the base 1 facing the second direction to form an opening 1201. In this case, the flange 12 can precisely avoid the second region 1b on one side in the second direction, so that the second region 1b can be connected to the outside of the base 1 through the opening 1201. Correspondingly, the base station module 30 can mate with the base 1 to form a receiving space 301 that communicates with the external environment through the opening 1201. The ground cleaning host 200, which mates with the base station module 30, can enter or exit relative to the base station module 30 through the opening 1201 in the flange 12.

[0099] Please refer to Figures 4 and 5. The opening 1201 is opened on the front side of the frame 10. One end of the second region 1b in the second direction is connected to the outer edge of the base 1 facing the front. In the first direction, the orthographic projection of the first region 1a includes a first projection part and a second projection part. The first projection part is located outside the orthographic projection of the second region 1b in the second direction, and the second projection part is located on both sides of the orthographic projection of the second region 1b in the third direction. At this time, the first region 1a can have a U-shaped or approximately C-shaped structure arranged around a portion of the periphery of the second region 1b.

[0100] It should be noted that the opening 1201 can be defined by the end of the base plate 11 on the front side of the frame 10 and the end of the flange 12 on the third direction, and the size of the opening 1201 is not less than the size of the second region 1b on the front side of the frame 10, so as to ensure that the floor cleaning host 200 can smoothly enter and exit relative to the frame 10 through the opening 1201. In this embodiment of the present disclosure, the base 1 with the flange 12 and the opening 1201 can be prepared by a stamping integral forming process.

[0101] Referring to Figure 5, the base plate 11 has a quadrilateral or near-quadrilateral structure. For example, the base plate 11 is rectangular or rounded rectangle, and the flanges 12 are connected at the four corners of the base plate 11 to ensure that the flanges 12 have sufficient strength. At this time, the orthographic projection of the base 1 in the first direction is a rectangular or near-rectangular structure.

[0102] In some embodiments, the size of the flange 12 in the first direction is not less than 50 mm. For example, the size of the flange 12 in the first direction can be set to any value among 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, etc.

[0103] The flange 12 helps to enhance the rigidity and bending resistance of the base 1, so as to prevent the base 1 from undergoing lateral deformation in a plane perpendicular to the first direction.

[0104] To further enhance the deformation resistance of the flange 12, reinforcing ribs can be provided at the connection between the flange 12 and the base plate 11, and / or, several reinforcing structures can be provided on the flange 12, such as the flange 12 protruding or recessed along its thickness direction. Taking the flange 12 formed on the left side of the base 1 in the third direction (i.e., the left side of the frame 10) as an example, multiple reinforcing ribs are distributed at the connection between the flange 12 and the base plate 11, and multiple strip-shaped reinforcing protrusions extending along the second direction are provided on the flange 12. Similarly, the flange 12 formed on the rear side of the base 1 in the second direction (and the back side of the frame 10) is also provided with the above-mentioned reinforcing ribs and reinforcing protrusions.

[0105] Please refer to Figures 5, 6, and 7. In this case, the base plate 11 has a supporting surface 1101 in the first region 1a for contacting the base station module 30. The supporting surface 1101 refers to the surface of the first region 1a of the base plate 11 for contacting the base station module 30. The base station module 30 is placed on the base 1 via the supporting surface 1101.

[0106] After the base station module 30 is placed on the base 1, the base station module 30 and the base 1 need to be fixed to ensure the stability and firmness of the connection between the two.

[0107] Referring to Figures 6 and 7, in this embodiment of the present disclosure, a fixing seat 113 is further provided on the first region 1a of the base 1. In the first direction, the orthographic projection of the fixing seat 113 on the base 1 is outside the orthographic projection of the second region 1b on the base 1, and the fixing seat 113 is disposed close to the second region 1b. The base station module 30 can be fixedly installed on the base 1 via the fixing seat 113 and is located above the second region 1b.

[0108] In some embodiments, the mounting base 113 is disposed near the connecting surface 1103 constituting the second region 1b and located within the first region 1a, as shown in Figures 8 and 9.

[0109] In some embodiments, the fixing seat 113 may be formed on the upper surface of the first region 1a and adjacent to the supporting plane, see Figures 5 and 9; of course, in other similar embodiments, the fixing seat 113 may also be adjusted to be located at the bottom of the base 1, i.e., disposed on the side of the base 1 facing away from the supporting plane, according to design needs.

[0110] The base station module 30 can be mounted on the base 1 via the mounting bracket 113 and is located exactly above the second area 1b, so as to enclose a receiving space 301 between the base station module 30 and the base 1 for cooperating with the ground cleaning host 200.

[0111] In some embodiments, the mounting base 113 has threaded holes, and the base station module 30 can be fixedly connected to the mounting base 113 by means of bolts or other structures passing through the threaded holes. Referring to Figure 5, the mounting base 113 is a plate-like structure with perforations, and the base station module 30 can be fixedly connected to the mounting base 113 by means of bolts, screws or other structures passing through the perforations.

[0112] Please refer to Figure 5. The fixing seat 113 can be set to protrude from the supporting surface 1101. At this time, there are at least two fixing seats 113 and they are respectively arranged opposite to each other on both sides of the supporting surface 1101 in the third direction. At this time, at least one fixing seat 113 is provided on both sides of the second region 1b in the third direction.

[0113] In some embodiments, the number of fixing seats 113 is at least three, for example, it can be three, four, five and six. Please refer to Figure 5, in which the number of fixing seats 113 is four and they are respectively located on both sides of the second region 1b in the third direction. Two fixing seats 113 are provided on each side and the two fixing seats 113 are spaced apart along the second direction (one fixing seat 113 is covered by the flange 12 and is not exposed).

[0114] In other similar embodiments, the fixing seat 113 may also be located on the side of the first region 1a facing away from the supporting surface 1101 in the first direction.

[0115] In this embodiment, the mounting base 113 is a lateral mounting base 113. At least a portion of the lateral mounting base 113 extends along a first direction relative to the supporting surface 1101 and has threaded holes, so as to be connected to the base station module 30 by bolts or other fastening structures in a direction perpendicular to the longitudinal beam 2. In other similar embodiments, at least one mounting base 113 may also be provided as a vertical mounting base 113. At least a portion of the vertical mounting base 113 is parallel to the supporting surface 1101 and has threaded holes, so as to be connected to the base station module 30 by bolts or other fastening structures in a direction parallel to the longitudinal beam 2.

[0116] To ensure a secure connection between the mounting base 113 and the base station module 30, in this embodiment, the mounting base 113 and the base plate 11 are an integral structure. In some embodiments, the base 1 can be prepared by stamping relevant sheet metal.

[0117] In other similar embodiments, the fixing base 113 and the base plate 11 can be configured as separate structures, and can be installed on the base plate 11 in a detachable connection manner.

[0118] The fixed base 113 prepared in the above manner cooperates with the base 1, so that the base station module 30 can be inserted or pulled out relative to the base 1 along the second direction. At this time, the base station module 30 can be loaded and unloaded relative to the base 1 through the second direction.

[0119] When the base station module 30 needs to be installed or removed relative to the base 1 along the first direction according to design requirements, in order to minimize the difficulty of installing or removing the base station module 30 and the base 1, in some embodiments, the base 1 can be set as a split structure.

[0120] For example, the base 1 includes a first component and a second component, and the second component and the first component can also be detachably connected by means of screws or other methods disclosed in related technologies.

[0121] In some embodiments, in a first direction, a portion of the orthographic projection of the outer contour of the second component is located within the orthographic projection of the first component, the second component constituting the base 1 encloses and forms a second region 1b, and the fixing seat 113 is disposed on the second component.

[0122] For example, the first component can be configured to include a flange 12 constituting the base 1 and a portion of the first region 1a, and the second component can include a second region 1b of the base 1 and a portion of the first region 1a. In this case, the mounting base 113 for fixing the base station module is located on the second component. The first component and the second component can be detachably connected through the overlapping portion in the first direction, and the connection portion between the second component and the first component is located below the first component. When it is necessary to remove the base station module 30 from the cleaning equipment 100, the cleaning equipment 100 can be laid down first to expose both the first component and the second component constituting the base 1. Then, the second component can be removed from the first component, so that the base station module 30, which is mounted on the second component through the mounting base 113, can be removed from the cleaning equipment 100. Subsequently, it can be selected whether to further separate the base station module 30 from the second component according to the needs of the operation.

[0123] Please refer to Figures 5-9. The base plate 11 provided in this embodiment has a recessed surface 1102 in the second region 1b for maintaining a distance from the base station module 30, and also includes a connecting surface 1103 connecting the recessed surface 1102 and the supporting surface 1101. The connecting surface 1103 serves as a transition surface, smoothly transitioning from the recessed surface 1102 to the supporting surface 1101, as shown in Figures 8 and 9.

[0124] It should be noted that at least a portion of the surface of the supporting surface 1101 is parallel to at least a portion of the surface of the sunken surface 1102, and in the first direction, any surface of the supporting surface 1101 is located above any surface of the sunken surface 1102, so as to further ensure that the sunken surface 1102 formed in the second region 1b does not directly contact the base station module 30, so as to ensure that the sunken surface 1102 is not deformed by pressure and can always maintain good strength.

[0125] Please refer to Figure 9. The supporting surface 1101 is located adjacent to the connecting surface 1103. Therefore, the supporting surface 1101 has strong rigidity and support strength, which can support the base station module 30 while ensuring that it is not easily deformed.

[0126] In this embodiment, the sunken surface 1102 is provided with a plurality of strip-shaped protrusions 117 spaced apart along the second direction. Referring to FIG5, any one of the strip-shaped protrusions 117 can extend along the third direction to the connecting surface 1103, so that the connecting surface 1103 also presents a concave-convex structure that smoothly transitions with the strip-shaped protrusions 117. At this time, with the cooperation of the connecting surface 1103 with the concave-convex structure, the structural strength of the base plate 11 formed by the connecting surface 1103, the sunken surface 1102 and the supporting surface 1101 is further improved, which can help improve the reliability of the supporting surface 1101 to a certain extent.

[0127] It is conceivable that the strip-shaped protrusions 117 formed in the second region 1b can help dissipate heat from items placed on the base 1 to a certain extent, such as helping the base station module 30 dissipate heat. Airflow can flow through the gap formed between the sunken surface 1102 and the base station module 30, and in conjunction with the uneven surface formed by the strip-shaped protrusions 117, it can accelerate heat dissipation to a certain extent.

[0128] In this embodiment, the strip-shaped protrusions 117 distributed in the second region 1b are not uniformly distributed in the second direction, and the distribution density of the strip-shaped protrusions 117 near the opening 1201 is greater than the distribution density of the strip-shaped protrusions 117 away from the opening 1201. Furthermore, the size of the strip-shaped protrusions 117 near the opening 1201 in the second direction is smaller than the size of the strip-shaped protrusions 117 away from the opening 1201 in the second direction. This structure helps to enhance the structural strength of the base plate 11 near the opening 1201, thereby reducing the impact of the opening 1201 on the overall strength of the base 1.

[0129] In order to further enhance the strength of the base plate 11, in addition to adding strip protrusions 117 to the second region 1b, the structure of the first region 1a can also be adjusted. For example, a corresponding concave-convex structure can also be added to the first region 1a.

[0130] In some embodiments, a plurality of spaced protrusions are also provided on a portion of the surface of the first region 1a. These protrusions can help improve the structural strength of the first region 1a.

[0131] Please refer to Figure 5. The protrusion is connected to the side of the supporting surface 1101 facing away from the connecting surface 1103. Its shape can be at least one of the following: strip, rectangle, T-shape or other similar T-shaped structure.

[0132] The protrusions formed on the supporting surface 1101 can be any at least one of strip, rectangular and T-shaped structures. Some of the protrusions only serve a certain structural reinforcement function, while others, while serving a structural reinforcement function, can also be used to help install and fix other devices of the cleaning equipment 100. For example, they can be used to install and fix any one or more of the following devices that cooperate with the cylinder 20: vibration damper 60, drainage pump and circuit board.

[0133] In some embodiments, the protrusions that assist in the installation and fixing of other devices include guide protrusions and assembly protrusions 116, as shown in Figures 5, 6, and 7. The guide protrusions can be used to cooperate with the base station module 30 to help guide the base station module 30 through the opening 1201 along the second direction to contact and place it into position with the support surface 1101. The assembly protrusions 116 can be used to install a vibration damper 60 that supports and cushions the roller.

[0134] Please refer to Figures 5, 6 and 7. The first region 1a of the base 1 is provided with a guide protrusion that cooperates with the guide structure 320 of the base station. The guide protrusion can be used to guide the base station module 30 to be inserted into the base 1 in a set direction.

[0135] In this embodiment, the direction is set to the second direction. In this case, the guide protrusion is used to guide the base station module 30 to be inserted into the base 1 through the opening 1201 along the second direction. In other similar embodiments, the set direction can be adaptively adjusted according to design needs, which will not be described in detail here.

[0136] In some embodiments, the guide protrusion includes a first guide protrusion 115, and the number of first guide protrusions 115 is at least two and located on the side of the second region 1b facing away from the opening 1201 in a second direction. The first guide protrusions 115 are arranged at intervals along a third direction and a guide gap is formed between any two adjacent first guide protrusions 115.

[0137] The base station module 30 has a guide structure 320 at one end in the second direction, and the size of the guide gap in the third direction is exactly matched with the guide structure 320. When the base station module 30 is inserted into the base 1 of the frame 10 in the second direction, the guide structure 320 can be inserted into the guide gap under the guidance of the first guide protrusion 115. At this time, the base station module 30 can be placed on the supporting surface 1101 of the base 1 under the guidance and limiting action of the first guide protrusion 115.

[0138] In some embodiments, the number of guide structures 320 may be one, two, or three. Referring to Figures 6 and 7, the number of guide structures 320 is three and they are arranged at intervals along the third direction. One guide structure 320 can cooperate with two first guide protrusions 115 through the guide gap, and the other two guide structures 320 are respectively located on the outer side of the two first guide protrusions 115 in the third direction.

[0139] In other similar embodiments, guide protrusions may also be provided, including second guide protrusions. The number of second guide protrusions is at least two, and they are respectively located on both sides of the second region 1b in the third direction. Along the second direction, the second guide protrusions are spaced apart from the fixing base 113 (the second guide protrusions are not shown in the figure). The base station module 30, inserted into the base 1 through the opening 1201, can move along the second direction under the guidance of the second guide protrusions to further improve the positioning accuracy of the base station module 30.

[0140] Please refer to Figures 5, 7 and 10. In this embodiment of the disclosure, the assembly protrusion 116 is located on both sides of the second region 1b in the third direction and on the side of the supporting surface 1101 away from the connecting surface 1103 in the third direction. The assembly protrusion 116 is used to install the vibration damper 60 of the support cylinder 20.

[0141] In some embodiments, the number of assembly protrusions 116 is three, two located on the right side of the first region 1a and one located on the left side of the first region 1a. All three assembly protrusions 116 can be used to achieve a detachable connection with the mounting base. The mounting base has lugs for connecting to the shock absorber 60. The shock absorber 60 can be mounted on the assembly protrusions 116 via the mounting base to support the cylinder 20.

[0142] The vibration damper 60, serving as a support component for the cylinder 20, can be mounted on the first region 1a of the base 1 via the assembly protrusion 116. Simultaneously, it maintains a distance from the base station module 30 mounted on the base 1 to ensure that the two do not structurally interfere with each other. Furthermore, this structure reduces the maintenance difficulty of the vibration damper 60, allowing maintenance personnel to quickly decouple the base plate 11 and the vibration damper 60 without affecting the assembly of the base station module 30.

[0143] It is understood that the frame 10 provided in this embodiment can maintain the overall height of the cleaning equipment 100 consistent with or substantially consistent with the height of traditional clothing processing equipment while installing and accommodating the cylinder 20 and base station module 30 of the cleaning equipment 100. This effectively reduces the space occupied by the cleaning equipment 100 in the height direction, helps to lower the center of gravity of the cleaning equipment 100, and improves its operational stability. The base 1 of the frame 10 can simultaneously fix and install the vibration damper 60 and the base station module 30. The vibration damper 60 supports the cylinder 20, and the base station module 30 cooperates with the base 1 to form an accommodating space 301 for the ground cleaning host 200 to dock. Therefore, it can effectively improve the internal space utilization of the cleaning equipment 100 and help reduce the assembly and maintenance difficulty of different components installed within the frame 10.

[0144] The frame provided in this disclosure can be used to install and accommodate the cylinder and base station module of a cleaning device. The frame includes a base, which can be used to install and support the base station module through a first area. Furthermore, in this disclosure, the first area of ​​the base can also be used to fix the base station module in place via a fixing seat, and an assembly protrusion can be used to install and fix a vibration damper for supporting the cylinder. This allows for separate fixing of the base station module and the cylinder on the base, reducing the difficulty of assembling and maintaining the cleaning module with this frame, and also helps to improve the internal space utilization of the cleaning device to some extent.

[0145] Based on the same concept, this disclosure also provides a cleaning device 100, which includes the frame 10 described in any of the above claims, and also includes a cylinder 20 and a base station module 30. Please refer to Figures 2 and 3. The cylinder 20 can be connected to the base 1 of the frame 10 through a vibration damper 60, and the base station module 30 can be enclosed with the base 1 to form the aforementioned accommodating space 301.

[0146] It should be noted that the base station module 30 has an abutment portion 310 for engaging with the first region 1a of the base 1. Referring to Figures 8 and 9, the abutment portion 310 is located on both sides of the base station module 30 in the second direction and can engage with the supporting surface 1101 of the base 1. At this time, the base station module 30 can be placed on the first region 1a of the base 1 through the abutment portion 310.

[0147] Additionally, the side of the base station module 30 opposite to the second region 1b can protrude relative to the abutment portion 310 toward the side closer to the sunken surface 1102 and maintain a certain gap with the sunken surface 1102. This gap can be used to accommodate and install a ramp 50 that allows the ground cleaning host 200 to travel on. Please refer to Figures 2 and 3 for the structure of the ramp 50.

[0148] In this embodiment of the disclosure, the base station module 30 also has a guide structure 320 at one end in the second direction. The specific location and structure of the guide structure 320 are described above and will not be repeated here.

[0149] In order to facilitate the insertion or removal of the base station module 30 relative to the frame 10 in the second direction, in this embodiment of the present disclosure, the base station module 30 is configured such that when the base station module 30 is disconnected from the frame 10, the base station module 30 can be removed or inserted relative to the frame 10 in the second direction.

[0150] The aforementioned disconnection refers to the disconnection of the base station module 30 from the fixed seat 113 on the base 1. At this time, the base station module 30 is only in contact with the base 1 through the supporting surface 1101.

[0151] When disconnected, the operator can directly insert or remove the base station module 30 relative to the base 1 along the second direction. At this time, the base station module 30 has a front-high and back-low trend in the first direction to ensure that the base station module 30 will not collide or interfere with other devices located above it during the insertion or removal process.

[0152] Based on the same concept, this disclosure also provides a cleaning system 1000, as shown in FIG1. ​​The cleaning system 1000 includes the cleaning device 100 described above, and also includes a floor cleaning host 200, which can enter and exit relative to the receiving space 301 via a ramp 50 to cooperate with the cleaning device 100.

[0153] The description of the various embodiments above tends to emphasize the differences between the various embodiments. The similarities or similarities between them can be referred to, and for the sake of brevity, they will not be repeated here.

[0154] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
