Description

Technical Field

[0001] This invention relates to the field of automatic cleaning equipment technology, and in particular to a self-cleaning control method and device. Background Technology

[0002] In the existing technology, in order to improve the user experience, some cleaning equipment on the market is equipped with a matching self-cleaning device. For example, floor scrubbers, as cleaning equipment, are matched with a base as a self-cleaning device. When the floor scrubber is not working, it is placed on the base. The base can charge the floor scrubber and can also perform self-cleaning. Users can put the equipment back on the base and start the program to automatically rinse and dry the roller brush of the floor brush.

[0003] The existing base has a first cleaning tank that can accommodate the roller brush of the cleaning equipment, and the roller brush can rotate within the first cleaning tank to achieve cleaning. However, the existing base cannot clean the wheels. During the cleaning process, the wheels often accumulate dirt. If the dirt accumulates over a long period of time, it can easily cause cross-contamination, making the cleaning equipment itself a source of pollution. This not only causes secondary contamination of the surface to be cleaned during the cleaning process, but may also produce odors. Therefore, cleaning the wheels of the cleaning equipment is a technical problem that urgently needs to be solved. Summary of the Invention

[0004] The purpose of this invention is to provide a self-cleaning control method and device to solve the technical problem that the base of a floor scrubber cannot effectively clean the wheels in the prior art.

[0005] The technical solution of the present invention is implemented as follows: The present invention provides a self-cleaning control method for a cleaning system, the cleaning system including a cleaning device and a base; the cleaning device includes a roller brush and a traveling wheel; the base is provided with a first cleaning groove for accommodating the roller brush and a second cleaning groove for accommodating the traveling wheel; the first cleaning groove and the second cleaning groove are connected; the method includes: during the self-cleaning process of the roller brush, controlling the traveling wheel to rotate in the second cleaning groove to achieve self-cleaning of the traveling wheel; wherein, at least during the time period during which the roller brush and the traveling wheel rotate together, the rotation speed of the traveling wheel is less than or equal to the rotation speed of the roller brush.

[0006] Currently, existing bases have a first cleaning tank that can accommodate the roller brush of the cleaning equipment, and the roller brush can rotate within the first cleaning tank to achieve cleaning. However, existing bases cannot clean the wheels. During the cleaning process, the wheels often accumulate dirt. If this dirt accumulates over time, it can easily cause cross-contamination, turning the cleaning equipment itself into a source of pollution. This not only causes secondary contamination of the surface to be cleaned during cleaning but may also produce odors. Therefore, cleaning the wheels of the cleaning equipment is a technical problem that urgently needs to be solved.

[0007] This application incorporates a second cleaning tank on the base, connected to the first cleaning tank containing the roller brush. This allows the traveling wheels to rotate within the second cleaning tank while the roller brush performs its self-cleaning process. The connection between the first and second cleaning tanks enables the sharing of cleaning fluid, achieving simultaneous cleaning of the traveling wheels during the roller brush's self-cleaning. This method not only solves the problem of cleaning the traveling wheels and preventing dirt residue, but also requires minimal structural modifications. It utilizes the base's roller brush cleaning system to clean the traveling wheels, resulting in a simple, low-cost, and effective cleaning solution. Furthermore, this design eliminates the need for a separate cleaning system for the traveling wheels and avoids altering the existing roller brush cleaning logic, maximizing cleaning range and effectiveness with minimal changes. Additionally, by controlling the traveling wheel rotation speed to not exceed the roller brush speed, this method effectively reduces liquid splashing within the second cleaning tank during cleaning, preventing secondary pollution to the ground around the base and the cleaning equipment itself.

[0008] Based on the above technical solutions, preferably, the cleaning system further includes: a liquid supply component, which is capable of supplying liquid to the first cleaning tank; controlling the rotation of the traveling wheel in the second cleaning tank during the self-cleaning process of the roller brush includes: controlling the liquid supply component to supply liquid to the first cleaning tank during the self-cleaning process of the roller brush; wherein, the liquid in the first cleaning tank can flow into the second cleaning tank; and controlling the rotation of the traveling wheel when there is liquid in the second cleaning tank.

[0009] In this way, during the self-cleaning process of the roller brush, the liquid supply component is controlled to inject cleaning fluid into the first cleaning tank. The liquid flows into the second cleaning tank through the connecting channel. The traveling wheel rotates to perform self-cleaning when the liquid level is sufficient. This achieves a liquid supply mode in which the first cleaning tank is injected with cleaning fluid, while the second cleaning tank shares the cleaning fluid. This simplifies the liquid supply path and avoids the structural complexity caused by setting up a separate liquid injection system for the traveling wheel. Through unified liquid supply and coordinated rotation, this method ensures that the traveling wheel is effectively cleaned under full immersion.

[0010] More preferably, when there is liquid in the second cleaning tank, controlling the rotation of the traveling wheel includes: when the liquid level in the second cleaning tank reaches a preset liquid level threshold, controlling the roller brush and the traveling wheel to rotate together, wherein the rotation frequency of the traveling wheel is less than or equal to the rotation frequency of the roller brush.

[0011] In this way, once the liquid level in the second cleaning tank reaches the preset threshold, the traveling wheels and roller brush are activated to ensure that the traveling wheels are cleaned under sufficient liquid coverage, avoiding ineffective rotation when there is no liquid or the liquid level is insufficient. Through liquid level feedback control, the reliability of the system's cleaning work is ensured, and the problem of incomplete cleaning of the traveling wheels due to uneven liquid distribution is solved.

[0012] Based on the above technical solutions, preferably, the cleaning system further includes: a recovery component, the recovery component including a suction component and a recovery container; the liquid in the first cleaning tank can be sucked into the recovery container by the suction component; the method further includes: during the self-cleaning process of the roller brush, controlling the suction component to start and sucking the liquid in the first cleaning tank and the second cleaning tank into the recovery container.

[0013] In this way, the suction component is activated during the cleaning process to suck the liquid in the first and second cleaning tanks into the recovery container. The connection structure between the first and second cleaning tanks enables centralized recovery of the liquid, achieving a single-tank suction and double-tank emptying drainage mode, improving drainage efficiency, and preventing liquid residue in the second cleaning tank after cleaning. This method simplifies the structure of the drainage system by unifying the suction path.

[0014] More preferably, the method further includes: controlling at least the rotation of the walking wheels during the process of controlling the start-up of the suction assembly.

[0015] In this way, during the suction process, the continuous or intermittent rotation of the traveling wheels is controlled, and the liquid adhering to the surface is thrown out by its centrifugal force, which is convenient for the suction components to recover, improves the thoroughness of liquid drainage, reduces liquid residue, and creates conditions for the subsequent drying stage. This method uses the movement of the traveling wheels to assist in liquid drainage and enhances the cleaning and drying effect on the surface of the traveling wheels.

[0016] Based on the above technical solutions, preferably, controlling the rotation of the walking wheel includes at least: controlling the walking wheel to rotate alternately in both forward and reverse directions, wherein the rotational speed of the walking wheel in reverse direction is less than the rotational speed of the walking wheel in forward direction.

[0017] In this way, the walking wheels are controlled to rotate alternately in both directions to assist in splashing water or changing the cleaning angle. The bidirectional rotation also enhances the rinsing effect of the cleaning fluid on the surface of the walking wheels, improving the uniformity of cleaning. At the same time, when the walking wheels slow down and rotate in reverse, it can reduce the liquid splashing that may be caused when the walking wheels rotate in the forward direction, thus solving the problem of dead corners that may exist when cleaning with the walking wheels rotating in a single direction.

[0018] Based on the above technical solutions, preferably, the method further includes: responding to a drying command by controlling the roller brush and the traveling wheel to rotate synchronously to dry the roller brush and the traveling wheel.

[0019] In this way, upon receiving the drying command, the roller brush and the traveling wheel are controlled to rotate, and the connecting structure allows hot air to be transferred from the first cleaning tank to the second cleaning tank, achieving synchronous drying of both. This integrates the drying of the roller brush and the traveling wheel, shortens the operation time, and improves the user experience. By connecting the cleaning, drainage, and drying stages, this method solves the problem that the traveling wheel cannot be effectively dried on the traditional base and is prone to becoming a source of moisture and pollution.

[0020] More preferably, the base is provided with a heating component, the cleaning device is provided with a suction component, and the method further includes: when the roller brush and the walking wheel are rotating, controlling the suction component and the heating component to start synchronously, so as to dry the roller brush with hot airflow.

[0021] In this way, while the roller brush and the traveling wheels are rotating, the suction component of the cleaning equipment and the heating component in the base are activated to form a hot airflow to dry the roller brush. This fully utilizes the air duct and suction of the cleaning equipment itself to dry the roller brush, thereby improving the drying efficiency of the roller brush. In addition, while the traveling wheels are rotating, they use the external air to shake off some of the moisture.

[0022] Based on the above technical solutions, preferably, the base is provided with a heating component and a fan component; the method includes: when the roller brush and the traveling wheel are rotating, controlling the fan component and the heating component to start synchronously, so as to dry the roller brush and the traveling wheel with hot airflow.

[0023] In this way, the fan and heating components within the base work together to generate a stable hot airflow. This hot airflow is guided through the air duct into the first cleaning tank to directly dry the roller brush. Simultaneously, through the connecting structure between the first and second cleaning tanks, some of the hot airflow can flow from the first to the second cleaning tank, drying the wheels synchronously. This achieves simultaneous active drying of both the roller brush and the wheels. The connecting structure acts as an air duct extension, allowing the hot air, which was originally only applied to the first cleaning tank, to naturally diffuse into the second cleaning tank. Thus, simultaneous drying of the roller brush and the wheels is achieved without the need for any additional air supply pipes or outlets for the wheels. This connecting structure ensures uniform flow and heat sharing of the hot air between the two tanks, not only improving drying efficiency and shortening operation time, but also fundamentally avoiding the problem of the wheels becoming a source of moisture and contamination due to lack of drying. It truly realizes a simple, low-cost, integrated cleaning and drying solution.

[0024] The present invention also provides a self-cleaning control device for a cleaning system, the cleaning system including a cleaning device and a base; the cleaning device including a roller brush and a traveling wheel; the base is provided with a first cleaning groove for accommodating the roller brush and a second cleaning groove for accommodating the traveling wheel; the first cleaning groove and the second cleaning groove are connected; the control device includes: a first control module, used to control the traveling wheel to rotate in the second cleaning groove during the self-cleaning process of the roller brush, so as to achieve self-cleaning of the traveling wheel; wherein, at least during the time period when the roller brush and the traveling wheel rotate together, the rotation speed of the traveling wheel is less than or equal to the rotation speed of the roller brush.

[0025] In this way, by executing the control logic described above through the control device, the actions of various actuators such as the roller brush motor, the walking wheel motor, the liquid supply component, the suction component, and the heating component are coordinated, realizing the automated and coordinated operation of the entire self-cleaning process. Through centralized control and process optimization, the control device fundamentally solves the problems of uncoordinated actions, low efficiency, and poor user experience in the multi-component, multi-stage cleaning process.

[0026] The present invention has the following advantages over the prior art: 1. The control logic enables dual-component collaborative cleaning, achieving effective cleaning of the roller brush and the walking wheels simultaneously. By controlling the liquid supply component to inject liquid only into the first cleaning tank and simultaneously controlling the walking wheels to rotate at low speed in the connected second cleaning tank, the walking wheels can share cleaning resources and receive effective rinsing, fundamentally solving the technical problem that the walking wheels of existing floor scrubbers cannot be automatically cleaned by the base. 2. During the drainage stage, the rotation of the walking wheels is controlled to actively eject residual water from the gaps using centrifugal force, significantly improving the thoroughness of drainage. At the same time, by alternating between forward and reverse rotation of the walking wheels, with the reverse rotation speed slower than the forward rotation speed, thorough cleaning is achieved while precisely suppressing liquid splashing that is very likely to occur during reverse rotation. In addition, the active water ejection control during the drainage stage greatly reduces the burden on subsequent drying, achieving energy consumption optimization. 3. The control commands for each stage of liquid injection, cleaning, drainage and drying are seamlessly connected, allowing users to complete the integrated cleaning and maintenance of the roller brush and wheels without intervention, significantly improving the user experience.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] This application provides a cleaning device, preferably a floor scrubber, including a floor brush 50, a main unit 70, and a handle; the main unit 70 is the main support structure of the cleaning device, the floor brush 50 is installed at the bottom of the main unit 70, and the handle is installed at the top of the main unit 70. The handle is for the user to hold, so that the user can control the direction of movement of the cleaning device and input user operation commands.

[0032] The main unit 70 and some components within the floor brush 50 together form a liquid supply assembly and a recovery assembly to achieve the cleaning function of the cleaning equipment. The liquid supply assembly includes a liquid supply container, a water pump, and a liquid supply pipe, while the recovery assembly includes a recovery container, a suction motor, and a suction pipe. The liquid supply container is used to hold the cleaning liquid (clean water or water containing detergent), and the recovery container is used to hold garbage and sewage. During cleaning, the water pump draws out the cleaning liquid and sprays it onto the surface to be cleaned through the liquid supply pipe. The roller brush 51 rotates and cleans the surface to be cleaned. At the same time, the suction motor sucks sewage, hair, and other fine garbage into the recovery container through the suction port adjacent to the roller brush 51 in the roller brush 51 compartment.

[0033] The control system is composed of some electronic components in the handle, main unit 70 and floor brush 50, including controller 60 as a data processing unit and various sensors. Controller 60 automatically generates control commands by collecting environmental data through sensors. Controller 60 is electrically connected to water pump, suction motor and roller brush motor 53. By executing automatically generated or user-input control commands, it effectively controls the cleaning module, liquid supply component and recycling component.

[0034] The cleaning system includes cleaning equipment and a base 10. In this embodiment, Figure 1 This is a schematic diagram of the cleaning device and base 10 in an embodiment of the present invention, as shown below. Figure 1As shown, the floor brush 50 includes a roller brush 51, a traveling wheel 52, a roller brush motor 53, and a traveling wheel motor 54; the roller brush motor 53 drives the roller brush 51 to rotate, and the roller brush 51 contacts and cleans the surface to be cleaned; the traveling wheel motor 54 drives the traveling wheel 52 to rotate; the base 10 includes an upper housing 11 and a lower housing 12, which are tightly connected by a snap-fit ​​and screw engagement, forming a receiving cavity 13 between the upper housing 11 and the lower housing 12, which provides installation space for internal functional components. The upper housing 11 is provided with a first cleaning groove 20 for accommodating the roller brush 51 and a second cleaning groove 30 for accommodating the traveling wheel 52; the first cleaning groove 20 and the second cleaning groove 30 are connected; when the floor brush 50 is placed on the base 10, the roller brush 51 is accommodated in the first cleaning groove 20 and the traveling wheel 52 is accommodated in the second cleaning groove 30; the components inside the machine body and the components inside the floor brush 50 together form a cleaning liquid supply system and a dirt recovery system to realize the cleaning function of the cleaning equipment.

[0035] Currently, the existing base 10 has a first cleaning tank 20 that can accommodate the cleaning equipment's roller brush 51, and the roller brush 51 can rotate within the first cleaning tank 20 to achieve cleaning of the roller brush 51. However, the existing base 10 cannot clean the traveling wheels 52. During the cleaning process, the traveling wheels 52 often accumulate dirt. If the dirt accumulates over a long period of time, it can easily cause cross-contamination, making the cleaning equipment itself a source of pollution. This not only causes secondary contamination of the surface to be cleaned during the cleaning process but may also produce an odor. Therefore, cleaning the traveling wheels 52 of the cleaning equipment is a technical problem that urgently needs to be solved.

[0036] like Figure 2 , Figure 3 As shown, in this embodiment, the base 10 also includes a connecting channel 40, which is disposed within the upper housing 11. One end of the connecting channel 40 is connected to the first cleaning tank 20, and the other end is connected to the second cleaning tank 30, forming a connecting structure. The angular direction of the connecting channel 40 is along the direction from the second cleaning tank 30 to the first cleaning tank 20. The bottom surface of the connecting channel 40 is inclined and forms an angle with the horizontal plane. The preferred inclination angle within the connecting channel 40 is 1°. This small inclination angle design is to ensure a balance between the drainage function and the structural space, which is sufficient to guide the water in the second cleaning tank 30 to flow into the first cleaning tank 20 through the connecting channel 40 under the action of gravity, avoiding water accumulation in the second cleaning tank 30, and avoiding structural abruptness and waste of internal space due to excessive angle. In other embodiments, in order to adapt to different cleaning liquid delivery requirements, the angle range of the bottom surface of the connecting channel 40 with the horizontal plane is 0-3°.

[0037] Furthermore, to better drain the cleaning fluid from the second cleaning tank 30, the height of the bottom of the second cleaning tank 30 is equal to or lower than the height of the bottom of the first cleaning tank 20. When the bottom of the second cleaning tank 30 is not higher than the bottom of the first cleaning tank 20, the liquid surface of the entire second cleaning tank 30 tends to flow into the first cleaning tank 20 under the influence of gravity. This, together with the connecting channel 40, constitutes a passive drainage system. The depth of the second cleaning tank 30 is preferably 2 cm, and its bottom shape is a portion of the side of a cylinder, allowing the second cleaning tank 30 to accommodate a portion of the traveling wheel 52. This ensures that the circumference of the traveling wheel 52 is immersed in water when it rotates, enabling better cleaning of the traveling wheel 52. In other embodiments, to allow the first cleaning tank 20 to accommodate traveling wheels 52 of different sizes, the depth of the second cleaning tank 30 is 1 cm to 4 cm.

[0038] like Figure 4 As shown, the base 10 is equipped with a heating assembly and a fan assembly. The heating assembly includes a heater 16 and a heating plate 18. The heating plate 18 is disposed at the bottom of the first cleaning tank 20 and corresponds to the interior of the housing 11. The heating plate 18 conducts heat when it comes into contact with the surface of the roller brush 51. The fan assembly includes a fan 14, an air duct 15, and an air outlet plate 17. The fan 14 is disposed in the receiving cavity 13; the air duct 15 is disposed in the receiving cavity 13, and the air inlet of the air duct 15 is connected to the air outlet of the fan 14; the air outlet of the air duct 15 is connected to the first cleaning tank 20. The heater 16 is located inside the air duct 15. The heater 16 includes a PTC heating element, which has the characteristics of rapid heating and constant temperature. The air outlet plate 17 is part of the side wall of the first cleaning tank 20. The air outlet plate 17 is provided with ventilation holes 171, which are connected to the air duct 15. The air volume generated by the fan 14 is heated by the heater 16 to form hot air, which is then guided into the first cleaning tank 20 through the air duct 15.

[0039] The cleaning system also includes a self-cleaning control device, such as Figure 5 As shown, the self-cleaning control device includes a controller 60 as a data processing device. The controller 60 includes a memory and a processor. The memory is used to store executable program code. The processor is a microcontroller (MCU) or a programmable logic controller (PLC) used to read the executable program code and run the computer program corresponding to the executable program code to perform one or more steps in a self-cleaning control method to realize multiple functions of the method.

[0040] The cleaning equipment's handle is equipped with buttons and / or a control panel and / or a voice module, connected to the controller 60, for recording user operation commands, parsing the commands, and sending them to the controller 60. Users can input various control commands to the cleaning equipment, including self-cleaning commands, by pressing buttons, touching the control panel, or entering voice commands. The cleaning equipment has multiple sensors installed inside or on the surface of the handle, main unit 70, or floor brush 50 to collect and detect environmental data. These sensors are connected to the controller 60 to convert the environmental data into computer-readable data and transmit it to the controller 60. Based on the detection, calculation, and judgment of the environmental data, the controller 60 can generate multiple control commands to control various electronic components.

[0041] The electronic components inside the main unit 70 include a display screen, a suction assembly 72, a liquid supply assembly 71, a battery charging and discharging module, and a rechargeable battery. The electronic components inside the floor brush 50 include a roller brush motor 51 and a walking wheel motor 52. The electronic components inside the base 10 include a fan assembly 14, a heating assembly, and a liquid level sensor. All of the above electronic components are connected to the controller 60. The controller 60 sends automatically generated control commands or user operation commands to each corresponding electronic component in chronological order to control the start / stop status and working mode of each electronic component.

[0042] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0043] Figure 6 This is a flowchart illustrating a self-cleaning control method for a cleaning device provided in an embodiment of this application, as shown below. Figure 6 As shown, the self-cleaning control method is applied to a cleaning system; the self-cleaning control method includes the following steps: S101, during the self-cleaning process of the roller brush, the traveling wheel is controlled to rotate in the second cleaning tank to achieve self-cleaning of the traveling wheel. Specifically, at least during the time period when the roller brush and the traveling wheel rotate together, the rotational speed of the traveling wheel is less than or equal to the rotational speed of the roller brush.

[0044] It should be noted that the traveling wheels can start rotating at the beginning of the self-cleaning process of the roller brush, or they can rotate during a certain period of the self-cleaning process. For example, the traveling wheels can be started after the cleaning solution flows from the first cleaning tank to the second cleaning tank to clean them, ensuring that the traveling wheels are in an effective cleaning environment when they rotate, thus avoiding dry rotation in the initial stage.

[0045] In one example, the rotation of the roller brush and the walking wheels could be controlled in response to a self-cleaning command.

[0046] In another example, the brush could be rotated in response to a self-cleaning command; specifically, the wheels could be rotated after the brush has been rotating for a period of time.

[0047] The self-cleaning command can be triggered by a button on the cleaning device or by a voice command; this application does not limit the specific triggering method.

[0048] In the embodiments of this application, the walking wheel can rotate continuously for a period of time or rotate intermittently.

[0049] It should be noted that the traveling wheels rotate continuously, which generates continuous centrifugal force, continuously throwing out moisture and loose dirt from the tire treads. At the same time, the tire surface of the traveling wheels maintains a constant relative motion and shearing action with the cleaning liquid or tank wall structure in the second cleaning tank, which is beneficial for peeling off strongly attached dirt. Under normal cleaning or when the dirt is relatively uniform, continuous rotation can complete the cleaning task in the most direct and efficient way within the predetermined time.

[0050] However, the wheels rotate intermittently. During the rotation phase, the wheels use mechanical force to flush out dirt and centrifugal force to throw it away. During the stationary phase, the wheels are immersed in the cleaning solution, allowing the liquid sufficient time to penetrate, soften, and dissolve the deep treads and stubborn dirt. This method is often more effective for penetrating, dried, or sticky dirt than simply rotating the wheels continuously.

[0051] The wheels can rotate in a forward, reverse, or alternating direction. Forward rotation refers to the direction of rotation of the cleaning equipment as it moves forward while cleaning the surface. Reverse rotation is the opposite of forward rotation.

[0052] It should be noted that cleaning in one direction (forward or reverse) may leave blind spots, especially for tires with complex tread patterns, where some tread surfaces may never be effectively cleaned. Controlling the wheels to rotate alternately in both directions allows for comprehensive two-way cleaning of the tire tread, ensuring that the front, back, and bottom of the grooves are all effectively cleaned, improving the thoroughness and completeness of the cleaning, and is particularly beneficial for removing particles such as sand stuck in the tread.

[0053] In this embodiment of the application, the time period during which the roller brush and the walking wheel rotate together can refer to the time period corresponding to the same cleaning stage in the self-cleaning process, or a certain time period in a certain cleaning stage.

[0054] In one example, the time period during which the roller brush and the wheels rotate together could refer to the soaking phase of the roller brush self-cleaning process. Alternatively, the time period could refer to the first half of the soaking phase of the roller brush self-cleaning process. Or, the time period could refer to the roller brush cleaning phase of the roller brush self-cleaning process. Alternatively, the time period could refer to the liquid suction phase of the roller brush self-cleaning process. Alternatively, the time period could refer to the second half of the liquid suction phase of the roller brush self-cleaning process. Or, the time period could refer to the drying phase of the roller brush self-cleaning process.

[0055] Specifically, within the aforementioned time period, the start time of the rotation of the walking wheel can be equal to or later than the start time of the rotation of the roller brush; the end time of the rotation of the walking wheel can be equal to or earlier than the end time of the rotation of the roller brush.

[0056] Specifically, during the aforementioned time period, the rotational speed of the traveling wheel is less than or equal to the rotational speed of the roller brush. The comparison of the rotational speeds of the traveling wheel and the roller brush does not specify the direction of rotation of the traveling wheel.

[0057] In some embodiments, the self-cleaning control method further includes: S201: During the self-cleaning process of the roller brush, the liquid supply component is controlled to supply liquid to the first cleaning tank; wherein the liquid in the first cleaning tank can flow into the second cleaning tank.

[0058] It should be noted that controlling the supply of cleaning fluid, by supplying fluid to the first cleaning tank, not only provides a medium for cleaning the roller brush, but also utilizes the interconnected structure of the first and second cleaning tanks to allow the liquid to automatically spread to the second cleaning tank, preparing a cleaning environment for the subsequent cleaning of the traveling wheels. This avoids setting up an additional independent fluid supply system for the traveling wheels, achieving dual use of the fluid. At the same time, it enables the cleaning of both the roller brush and the traveling wheels, improving resource utilization efficiency. The timing of starting the fluid supply component can be varied.

[0059] In one example, in response to a self-cleaning command, the liquid supply assembly could be activated first to inject liquid into the first cleaning tank, and then the roller brush could be rotated.

[0060] In another example, the roller brush can be controlled to run idle for pre-cleaning first, and then the liquid supply assembly can be controlled to inject liquid into the first cleaning tank.

[0061] S202: When there is liquid in the second cleaning tank, control the rotation of the walking wheels.

[0062] It should be noted that the wheels can rotate when there is liquid in the second cleaning tank, or they can rotate some time after the liquid has been present in the second cleaning tank.

[0063] In one example, timed liquid supply control can be implemented, setting a fixed liquid supply time (e.g., 10 seconds). When the time is up, it is assumed that there is liquid in the second cleaning tank, and then the walking wheels are controlled to rotate.

[0064] In another example, liquid level feedback control can be implemented, with a liquid level sensor (e.g., an electrode sensor) installed at the bottom of the second cleaning tank. When the liquid level sensor is triggered, a self-cleaning command controls the walking wheels to start rotating.

[0065] In this embodiment of the application, this prerequisite is set so that the liquid level in the first cleaning tank can rise and flow into the second cleaning tank, ensuring that the wheels are effectively immersed in the cleaning liquid for cleaning when they rotate, rather than running idly. The cleaning control of the wheels is achieved through timed control or feedback from the liquid level sensor, avoiding ineffective cleaning due to insufficient liquid and improving the cleaning effect.

[0066] In some embodiments, the self-cleaning control method further includes: S301, when the liquid level in the second cleaning tank reaches the preset liquid level threshold, the roller brush and the traveling wheel are controlled to rotate together, wherein the rotation frequency of the traveling wheel is less than or equal to the rotation frequency of the roller brush.

[0067] It should be noted that the preset liquid level threshold can be set to multiple levels. For example, a first threshold can be set to a low liquid level that covers the bottom of the second cleaning tank to trigger low-speed pre-wetting of the wheels; a second threshold can be set as the formal cleaning liquid level, covering 1 / 3 to 1 / 2 of the wheel radius in the second cleaning tank to trigger the wheels to rotate during formal cleaning. This effectively ensures that the wheel tread has a good contact area and wetting effect with the liquid when it rotates, guaranteeing cleaning ability while avoiding the problem of liquid splashing due to excessive liquid level.

[0068] In the embodiments of this application, rotation frequency can refer to the rotation speed per unit time or the number of starts and stops per unit time.

[0069] In one example, the roller brush rotates continuously at a constant high speed (e.g., 800 rpm), while the traveling wheel rotates at a lower constant speed (e.g., 200 rpm).

[0070] In another example, the roller brush rotates continuously, while the traveling wheel performs intermittent rotations (e.g., rotating for 10 seconds and stopping for 2 seconds), with an average rotation frequency lower than that of the roller brush.

[0071] In another example, when the liquid level in the second cleaning tank reaches the first threshold, the roller brush rotates continuously, and the traveling wheel rotates continuously at a low speed (e.g., 50 rpm) to immerse the traveling wheel in the second cleaning tank; when the liquid level in the second cleaning tank reaches the second threshold, the roller brush rotates continuously, controlling the traveling wheel to rotate intermittently at a higher speed (e.g., at a speed of 500 rpm, rotating for 8 seconds and stopping for 1 second).

[0072] In this embodiment, the traveling wheel is located in the second cleaning tank. Its rotation causes the liquid in the tank to splash. By controlling its rotation frequency, especially by using a lower speed or intermittent rotation, the intensity of liquid splashing can be reduced. By controlling the speed of the traveling wheel, the performance of the connected dual-tank cleaning system is optimized. In addition, during the rotation of the roller brush and the traveling wheel, the roller brush and the traveling wheel can be controlled to switch between forward and reverse rotation, or alternate between forward and reverse rotation, thereby improving the efficiency, effectiveness and reliability of the self-cleaning process as a whole.

[0073] In some embodiments, the self-cleaning control method further includes: S401, during the self-cleaning process of the roller brush, the suction component is activated and the liquid in the first and second cleaning tanks is sucked into the recovery container.

[0074] In one example, after the roller brush and wheels have finished cleaning and stopped rotating, the suction assembly can be controlled to draw the liquid into the recovery container.

[0075] In another example, the suction assembly can be controlled to draw liquid into a recovery container while the roller brush and wheels are rotating and cleaning.

[0076] Specifically, during the final cleaning period when the roller brush and cleaning wheel are rotating, the suction component is synchronously controlled to draw the liquid into the recovery container.

[0077] In the embodiments of this application, different start times for the suction component can adapt to different cleaning scenarios. Suctioning after the roller brush and the walking wheel stop simultaneously can drain the liquid more thoroughly. When the method of washing and suctioning at the same time is adopted, the dirt in the flowing liquid can be kept less attached to the walking wheel.

[0078] In some embodiments, the self-cleaning control method further includes: S501, during the process of controlling the start of the suction assembly, at least the rotation of the walking wheels is controlled.

[0079] In one example, the wheels rotate continuously to control the suction assembly to start, and the wheels continue to rotate until the suction ends.

[0080] In another example, when the suction component executes the liquid suction command, the walking wheels are controlled to rotate for at least a certain period of time during the suction.

[0081] Specifically, at the end of the liquid suction period, after most of the liquid has been removed by the suction components, the walking wheels are then controlled to rotate to agitate and remove any remaining liquid from the tire treads.

[0082] It should be noted that during the suction process, the centrifugal force generated by controlling the rotation of the wheels can throw some of the liquid embedded in the tire tread grooves or seams off the tire surface, and control the rotation of the wheels to agitate the remaining liquid in the grooves so that the liquid can flow.

[0083] In some embodiments, the self-cleaning control method further includes: S601, in response to a drying command, controls the roller brush and the traveling wheel to rotate synchronously for drying the roller brush and the traveling wheel.

[0084] In one example, a drying command is triggered, causing the roller brush and wheels to rotate synchronously. The centrifugal force generated by the rotation of the roller brush and wheels can fling out residual liquid from the crevices and surfaces. The liquid flung out by the roller brush can be captured and removed by the airflow of the suction component. At the same time, the residual liquid flung out by the wheels flows from the second cleaning tank into the first cleaning tank and is also removed by the suction component.

[0085] In another example, a drying command is triggered, and the roller brush and wheels rotate synchronously. During the roller brush's rotation, the suction component can be deactivated, and drying is achieved through the contact between the roller brush and the air during rotation. Alternatively, the suction component can be turned on for a period of time at the beginning of the roller brush's rotation and then turned off. This allows water splashed out by the roller brush to be absorbed when there is still a lot of moisture at the beginning of the drying process. Similarly, the wheels can maintain a similar drying principle as the roller brush; for example, their surface can be dried through contact with external air during rotation.

[0086] Synchronous rotation of the roller brush and the traveling wheel can refer to controlling the roller brush and the traveling wheel to start rotating at the same time, without limiting the rotation speed and frequency of the roller brush and the traveling wheel.

[0087] In another example, in response to a drying command, the control roller and the traveling wheel are started synchronously and a fixed speed is set. The roller rotates continuously at a constant high speed (e.g., 800 rpm), while the traveling wheel rotates at a lower constant speed (e.g., 200 rpm) until the drying command ends.

[0088] In another example, during the initial period in response to the drying command, the roller brush is controlled to rotate continuously at a constant high speed, while the traveling wheel rotates at a lower constant speed. During the period from the drying command to the end of the drying period, the rotation direction of the roller brush or the traveling wheel can be switched to avoid drying in a single direction. The alternation of forward and reverse rotation allows the brush bristles and the tire treads of the traveling wheel to throw out residual liquid from different directions, which helps to remove residual liquid hidden in the fiber roots or groove dead corners.

[0089] In some embodiments, the self-cleaning control method further includes: S701 controls the simultaneous activation of the suction and heating components while the roller brush and wheels are rotating, so as to dry the roller brush with hot airflow.

[0090] In this embodiment, the heating component is activated to generate heat in the first cleaning tank. The suction component continuously suctions, causing the airflow to combine with the heat to form a hot airflow, which directly acts on the rotating roller brush to dry the roller brush. The traveling wheel rotates synchronously, and the airflow generated by its own rotation dries the surface of the roller brush until drying is complete.

[0091] Synchronous rotation of the roller brush and the traveling wheel can refer to controlling the roller brush and the traveling wheel to start rotating at the same time, without limiting the rotation speed and frequency of the roller brush and the traveling wheel.

[0092] It should be noted that, in controlling the drying of the roller brush, the heat generated by the heating component is controlled to be raised to a preset temperature, for example, the temperature can be maintained at 45°C for a preset constant temperature time, for example, maintaining the temperature for 10 minutes; after the constant temperature time is reached, the heating component is turned off, but the suction component continues to run for a period of time, for example, continuously suctioning for 2 minutes to remove residual heat, so that the roller brush cools down to close to the ambient temperature until the drying is completed and the roller brush rotation stops.

[0093] In some embodiments, the self-cleaning control method further includes: S801 controls the simultaneous activation of the fan assembly and heating assembly while the roller brush and traveling wheels are rotating, so as to dry the roller brush and traveling wheels with hot airflow.

[0094] In this embodiment, in response to a drying command, the heat source and air source required for the drying function are fully integrated inside the base. After responding to the drying command, the fan assembly starts first, driving airflow. The airflow is heated after passing through the synchronously started heating assembly (such as a PTC heater). The resulting high-temperature airflow is actively and directionally blown to the roller brush in the first cleaning tank through the specially designed air duct and air outlet inside the base. Through the connection between the first and second cleaning tanks, part of the hot airflow can also act on the traveling wheels in the second cleaning tank. At the same time, the rotation of the roller brush and the traveling wheels themselves forms centrifugal drying and surface air disturbance, which works in conjunction with the externally actively blown hot airflow to accelerate the drying process.

[0095] In one example, the heating component is activated, and the fan component moves synchronously to transfer heat. When the temperature reaches a preset value, it is maintained at a constant temperature for a period of time. Under the stable temperature, the moisture on the surface of the rotating roller brush and the traveling wheel is dried. After the constant temperature time ends, the heating component is stopped, and the fan component continues to run for a preset cooling time. The continuous airflow carries away the residual heat and moisture on the roller brush and the traveling wheel, reducing the temperature of the roller brush and the traveling wheel to close to the ambient temperature. After the cooling time ends, the fan component is stopped, and the rotation of the roller brush and the traveling wheel is stopped at the same time.

[0096] Synchronous rotation of the roller brush and the traveling wheel can refer to controlling the roller brush and the traveling wheel to start rotating at the same time, without limiting the rotation speed and frequency of the roller brush and the traveling wheel.

[0097] It should be noted that the roller brush and the traveling wheel are controlled to rotate synchronously. During the drying process, most of the hot airflow is directed to the roller brush in the first cleaning tank for drying, and part of the hot airflow is diverted to the second cleaning tank to dry the traveling wheel. The drying of the traveling wheel does not rely solely on the airflow generated by its own rotation, but also benefits from the contact between the hot airflow partially introduced from the first cleaning tank and the rotating traveling wheel, further improving the drying efficiency.
