[0020] In the current market, household floor scrubbers are becoming increasingly popular. Self-cleaning after cleaning has become a trend in floor scrubbers. Self-cleaning can greatly reduce secondary pollution caused by dirt adhering to the agitator fibers of surface cleaning equipment, effectively removing dirt attached to the agitator.

[0021] Since the self-cleaning cycle usually uses clean water to repeatedly wash the agitator, the fuzz on the surface of the agitator still has a certain degree of moisture after self-cleaning. Even if the speed of the agitator is increased to remove excess water through centrifugal force, the moisture on the fuzz of the agitator cannot be completely removed after the self-cleaning cycle ends. This can lead to the possibility of bacteria growing in a humid environment.

[0022] To address this issue, existing technologies include hot air drying of the agitator after self-cleaning to thoroughly remove moisture from the agitator's fibers, thus preventing the potential growth of bacteria and microorganisms within them. For example, Chinese patent application ZL202110456057.2 describes a hot drying mechanism within the base that allows for the hot drying of the cleaning equipment's roller brush, improving cleaning efficiency and extending the equipment's lifespan. Controlling the operation of the fan and heating element on the base station enables the heating and dispersion of airflow, achieving thorough heating and hot drying of the cleaning equipment. Furthermore, by incorporating a tray and air guide, the airflow from the hot drying mechanism can be directed towards the cleaning trough on the tray, further enhancing the hot drying effect.

[0023] Another method of hot water self-cleaning involves setting up a heating module in the cleaning area of ​​the stirring component of the base station. The heating module conducts heat to the contact area of ​​the cleaning component to heat the self-cleaning water in the contact area, thereby achieving hot water self-cleaning.

[0024] Currently, drying of wet surface cleaning devices, such as floor scrubbers, has become a trend. However, most base stations with heat drying functions on the market require a long time to completely dry the cleaned parts.

[0025] The base station and surface cleaning equipment maintenance methods described in this article can improve the efficiency of thermal drying of cleaned parts depending on different maintenance modes. In some examples of base stations, the base station may be configured with enhanced heating components. In some examples, the enhanced heating components can operate on both the thermal drying cycle and the self-cleaning cycle preceding the thermal drying cycle.

[0026] In some implementations, the control device can employ various mechanisms and algorithms to determine the maintenance mode, thereby determining different self-cleaning and hot-drying cycle strategies based on the user's mode selection. It can also automatically determine the self-cleaning and hot-drying cycle strategies according to environmental changes, eliminating excessively long maintenance waiting times while ensuring maintenance efficiency.

[0027] Figure 1 An example is shown that supports surface cleaning equipment for performing maintenance according to various aspects of this disclosure. The term "surface cleaning equipment" may be used herein to describe various types of household cleaning equipment, including autonomous handling equipment configured to provide some semi-autonomous or autonomous capabilities. Examples of household cleaning equipment include: floor scrubbers, vacuum cleaners with mopping functions, robotic vacuum cleaners with scrubbing functions, window cleaning robots, etc.

[0028] In embodiments where the surface cleaning device is a floor scrubber, the surface cleaning device may include an onboard processing device configured to receive information or instructions, such as information or instructions from a human operator (e.g., via a remote computing device), and to semi-autonomously manipulate the surface cleaning device to clean the floor and / or perform base station maintenance of the surface cleaning device based on the received information or instructions.

[0029] Figure 1This is a surface cleaning system architecture diagram according to one aspect of the present disclosure. The surface cleaning system 100 may support a mechanism for cleaning and maintenance of the surface cleaning device 210. In some embodiments, the surface cleaning device 210 may be configured to perform a semi-autonomous or autonomous dirt particle collection process. For example, the surface cleaning device 210 may include a wet floor cleaning device. The surface cleaning device 210 may be configured to identify the degree of dirt on the floor and the usage time of the cleaning components of the surface cleaning device 210 within a cleaning cycle. Some examples of identifying the degree of dirt on the floor and the usage time of the cleaning components may be based on sensor information. After the surface cleaning device 210 determines that the cleaning components should be maintained, it may pause operation and record the current working position of the surface cleaning device 210. The base station 220 of the surface cleaning device 210 may be configured with a system capable of performing self-cleaning cycles and thermal drying cycles, which may begin performing corresponding cleaning and maintenance operations when the surface cleaning device 210 is housed and supported on the base station 220.

[0030] In some implementations, various mechanisms and algorithms can be employed to determine the maintenance mode of the cleaning components of the surface cleaning device 210 to adapt to the current working conditions. The current working conditions can be defined by the user and / or identified by the surface cleaning device using environmentally relevant occupancy data, such as the area and geographical location of areas already cleaned in a home, and records of the dirt levels on cleaned floors. By automatically selecting maintenance modes through mechanisms and algorithms, the corresponding maintenance mode can be invoked on the base station 220 to maintain the surface cleaning device, thus reducing downtime or waiting time.

[0031] like Figure 1 In some implementations, the surface cleaning system 100 may further include an access point 110, a server 120, a remote control device 130, a database 140, and a wireless communication link 150. The server 120 may include a data server, a cloud server, a server associated with an automation service provider, a proxy server, a mail server, a network server, an application server, a database server, a communication server, a home server, a mobile server, or any combination thereof. For example, the surface cleaning device 210 may upload data (such as notifications) to an application hosted on the server 120 to publish data related to autonomous functions performed by the surface cleaning device 210. For example, a user may view the data published by the surface cleaning device 210 through an application running on the remote control device 130 to view the functions performed by the surface cleaning device 210. The server 120 may also transmit various information to the surface cleaning device 210, such as location information, motion control commands, and other information, instructions, or commands related to the autonomous operation of the surface cleaning device 210.

[0032] Database 140 can store data, which may include operational information such as location information, control commands, consumable information (e.g., agitator information, filter information), water level information, dirt information, and battery information, as well as other information, instructions, or commands related to the maintenance operations of the surface cleaning equipment (e.g., the duration of the self-cleaning cycle, the duration of the heat drying cycle, the charging power of the base station 220 during the maintenance of the surface cleaning device, etc.). Surface cleaning equipment 210 can retrieve the stored data from database 140 via access point 110.

[0033] In some cases, surface cleaning equipment can also communicate directly with another device (e.g., using point-to-point (P2P) or device-to-device (D2D) protocols), such as smartphones, Bluetooth devices, Wi-Fi devices, mobile stations, user stations, mobile clients, etc.

[0034] The wireless communication link 150 shown in the surface cleaning system 100 may include uplink (UL) transmission from the surface cleaning device to access point 110 or server 120, and / or downlink (DL) transmission from access point 110 or server 120 to the surface cleaning device. Downlink transmission may also be referred to as forward link transmission, and uplink transmission may also be referred to as reverse link transmission. The wireless communication link 135 may transmit bidirectional and / or unidirectional communication. The wireless communication link 135 may include one or more connections, including but not limited to Wi-Fi, Bluetooth, point-to-point, LAN, wireless local area network (WLAN), Ethernet, fiber optic, and / or other connection types associated with the wireless communication system.

[0035] Figure 1 An example of an environment 200 supporting surface cleaning equipment performing maintenance on base station 220 according to various aspects of this disclosure is also shown. Environment 200 can implement various aspects of surface cleaning system 100.

[0036] In some examples, environment 200 can be part of a structure, such as a residential or commercial building. For example, environment 200 can be a home, specifically a room, including one or more different floor materials and objects throughout the room. The surface cleaning device can be configured to perform cleaning functions within the scope of the home. For example, the surface cleaning device can perform a semi-autonomous (or autonomous) collection process of surface dirt particles within the aforementioned geographical boundaries under the manual control of a user, including: during operation, a cleaning fluid is supplied from a fluid supply container to a dispenser, and from the outlet of at least one dispenser to a cleaning element. The fluid flows onto the cleaning element such that the surface to be cleaned, such as a bare floor surface, can be wetted or dampened via the fluid indirectly delivered through the cleaning element. A recovery system can operate simultaneously with the dampened cleaning element. More specifically, during the operation of the recovery system, a vacuum cleaner draws in fluid carrying debris through suction nozzles and draws this fluid into a downstream recovery container, where the debris and wastewater are substantially separated from the working air. The airflow then exits the surface cleaning device through a suction source.

[0037] Typically, in traditional environments, the cleaning efficiency of surface cleaning equipment decreases after a cleaning cycle or within a cycle because the increasing dirt on the cleaning components exceeds the amount of dirt automatically removed during cleaning. At this point, the collection process needs to be paused, and maintenance of the cleaning components needs to be performed at base station 220. Maintenance at base station 220 typically includes self-cleaning and thermal drying, with thermal drying requiring a longer time interval. Therefore, this limits the number of areas the surface cleaning equipment can operate in environment 200, or causes unnecessary delays due to sudden ground soiling events requiring cleaning. As described in this paper, a highly efficient maintenance mechanism for surface cleaning equipment can be configured on base station 220, thereby eliminating the limitations and delays associated with manual intervention.

[0038] Figure 2-4 This is a schematic diagram of an embodiment of base station 220 related to this disclosure. For example... Figure 2-4 As shown, this disclosure provides a base station 220 for docking surface cleaning equipment. The base station 220 not only accommodates the surface cleaning equipment but also performs self-cleaning and hot-drying cycles for the agitator of the surface cleaning equipment docked on the base station 220. Furthermore, the base station 220 also has the function of providing electrical energy to the surface cleaning equipment docked thereon, charging the rechargeable battery of the surface cleaning equipment using the electrical energy provided by the base station 220.

[0039] The base station 220 includes key components such as a housing 221, a tray 222, and a storage section 223. The storage section 223 is located below the tray 222, is firmly fixed to the tray 222, and together with the tray 222, forms at least a portion of the outer surface of the base station 220.

[0040] A cleaning zone 224 is provided within the housing 221. This cleaning zone 224 is located on a tray 222, at its front end. When the surface cleaning equipment is docked at the base station 220, the agitator of the surface cleaning equipment is contained within the cleaning zone 224. At this time, the cleaning zone 224 can store cleaning liquid, enabling self-cleaning when the agitator of the surface cleaning device operates within it.

[0041] like Figure 2 and 3 As shown, in one embodiment, during the self-cleaning process, the heat conduction element 225 transfers the heat generated by the heating assembly 226 within the base station 220 to the cleaning area 224. In this way, the liquid within the cleaning area 224, including the liquid adhering to the agitator fibers and the liquid accumulated within the cleaning area 224, will be effectively heated to achieve sterilization and disinfection.

[0042] The heat-conducting component 225 is at least partially disposed within the clean area 224 and can be stably fixed to at least a portion of the base station 220 via the frame portion. In one example, the frame portion is mounted and fixed to the frame of the heating assembly 226. Because the frame is made of a high-temperature resistant and low-deformation material, the frame can be embedded into the clean area 224 with an interference fit, and then sealed using conventional soft adhesive. This design ensures both effective heat conduction and maintains the integrity of the clean area 224 under high-temperature conditions.

[0043] In one embodiment, during the heat drying process, the heating component 226 of this disclosure, along with the heat generated by the in-station heating group 226, transfers heat to the cleaning area 224. In one embodiment, the hot airflow during the heat drying process is configured on the base station 220 to be directed towards the cleaning area 224, particularly the heat conduction element 225. Thus, during the heat drying process, the cleaning component of the surface cleaning equipment can simultaneously receive heat transferred from the heat conduction element 225 and heat transferred from the hot airflow.

[0044] To achieve heating of the airflow inside base station 220, such as Figure 3 As shown, in one embodiment, a heating assembly 226 is disposed inside the housing of the base station 220 for installation in the air duct of the surface cleaning system to heat the airflow in the air duct for use in the heat drying process.

[0045] like Figure 2 and 3As shown, the housing 221 of the base station 220 forms a cavity structure inside, and the housing 221 has an air inlet 227 and an air outlet 228. One or more blowers 229 are arranged between the air inlet 227 and the air outlet 228. The blowers 229 are located inside the housing 221. When they are powered on, a pressure difference is generated inside the housing 221. A negative pressure is generated at the air inlet 227, and under the action of atmospheric pressure, the airflow from the outside is sent into the air inlet 227. A positive pressure is generated at the air outlet 228, thereby overcoming the action of atmospheric pressure and sending the airflow inside the base station 220 out of the air outlet 228. Under the continuous action of the blowers 229, an airflow path is generated from the air inlet 227 to the air outlet 228.

[0046] like Figure 3 and 4 As shown, according to an example of this disclosure, a preheating assembly 2261 is provided on the flow path through which the airflow passes. The preheating assembly 2261 is used to receive airflow from upstream of the airflow path. As described above, in one embodiment, the upstream airflow originates from the output airflow of a blower 229, and the preheating assembly 2261 is located downstream of the blower 229, thus heating the upstream airflow from the blower 229 to form a preheated airflow F1.

[0047] The preheated airflow F1 moves downstream under the guidance of the air duct. Downstream of the preheating component 2261, one or more postheating components 2262 are set to receive the preheated airflow F1 and heat the preheated airflow F1 to form a secondary heated airflow F2. The secondary heated airflow F2 is introduced into the clean area 224 through the air outlet 228.

[0048] In one example of this disclosure, the airflow path is restricted within the housing of base station 220 by an airflow guiding device. The airflow flows between the inlet and outlet of the airflow guiding device, particularly from the inlet to the outlet. The airflow guiding device is typically located in the center of the housing of base station 220 to prevent significant deviation in the airflow trajectory and ensure uniform dispersion from the outlet. The airflow guiding device typically includes a pair of symmetrically arranged guides 230, 231 to confine the airflow between the guides 230, 231.

[0049] In one example, a pair of guide tubes 230 and 231 form a diffusion structure, which can meet the airflow guidance requirements while ensuring that the airflow is reflected between the guide tubes through the reflection principle, ensuring that the airflow flows out uniformly at the outlet without significantly reducing the flow velocity. By setting an airflow guiding device to guide the airflow from the blower 229 to the heating mechanism, the airflow utilization efficiency of the heating mechanism can be increased. Without requiring excessive power, the blower 229 can meet the required airflow, reducing the power consumption of the base.

[0050] like Figure 3 As shown in one example, a preheating assembly 2261 is located at the inlet 233 of a diffusion structure formed by a pair of guide tubes 230 and 231. It receives airflow from the blower 229, which, after passing through the preheating assembly 2261, is introduced into the interior of the diffusion structure and continues downstream. A postheating assembly 2262 is located at the outlet 234 of the diffusion structure, receiving the preheated airflow F1 and heating it to form a secondary heated airflow F2. Due to the diffusion structure, it is necessary to ensure that the airflow passes through the heating assembly 226 both when entering and exiting the diffusion structure. Correspondingly, the lateral width of the postheating assembly 2262 is greater than the lateral width of the preheating assembly 2261 to ensure that the airflow is heated. The secondary heated airflow F2 is introduced into the cleaning zone 224, or the location of the cleaning element, which significantly improves the drying efficiency of the thermal drying cycle.

[0051] In one example, a heating zone is formed within the cleaning zone. This heating zone is implemented by a heat conductor 225. The heat conductor 225 is configured such that at least a portion of the cleaning element is in contact with the heat conductor 225 when the surface cleaning device is located on the base station 220. The heat conductor 225 is configured to transfer heat to at least a portion of the cleaning zone during the thermal drying cycle of the surface cleaning device to heat residual water from, for example, lint on the agitator within the cleaning zone, thereby improving the evaporation efficiency of the moisture and achieving more efficient thermal drying of the agitator.

[0052] During the hot drying cycle, the heat transfer element 225 transfers heat to the cleaning zone 224, accelerating the evaporation of residual water from the rotating agitator. This heating effect further enhances the evaporation of residual water from the fluff, building upon the drying process of the secondary heating airflow F2, while simultaneously reducing bacterial activity or directly killing bacteria. Specifically, the heat transfer element 225 is positioned in the cleaning zone, contacting the rotating agitator placed there, transferring heat to the surface of the cleaning element and raising the temperature of the residual liquid on its surface. Under the action of the secondary heating airflow F2, the residual liquid can evaporate more efficiently, achieving the drying effect of the cleaning element in a short time, thus realizing rapid hot drying of the agitator and reducing the user's waiting time.

[0053] like Figure 2 As shown in one aspect of this disclosure, in one example, the front heating assembly 2261 includes a PTC heating element. The PTC heating element is securely fixed inside the base station 220 housing by a bracket, which is preferably made of a high-temperature resistant material to prevent deformation after heating, which could lead to functional failure of the heating mechanism.

[0054] like Figure 2 As shown in one aspect of this disclosure, the rear heating assembly 2262 includes a PTC heating element. The PTC heating element is securely fixed inside the base station 220 housing by a bracket, which is preferably made of a high-temperature resistant material to prevent deformation after heating, which could lead to functional failure of the heating mechanism. In one example, the rear heating assembly 2262 conducts heat from inside the base station 220 housing to the clean area 224 through a heat conduction element 225 fixedly connected to it and having a thermal conductivity relationship.

[0055] The heat transfer element 225 is configured to transfer heat to the agitator of the surface cleaning device. The application scenarios for the heat transfer element 225 mainly cover installation within the cleaning area 224 of the base station 220 to assist in cleaning operations. For example, when the heat transfer element 225 is installed within the cleaning area 224 of the base station 220, at least a portion of the heat transfer element 225 is connected to a heater disposed on the base station 220 via heat transfer, transferring heat from the heater of the base station 220 to the cleaning area 224.

[0056] The heat transfer element 225 is positioned in the middle of the cleaning zone 224, and its main function is to transfer heat energy to the agitator of the surface cleaning device through efficient heat conduction. Specifically, when the heat transfer element 225 is installed in the cleaning zone 224 of the base station 220, at least a portion of the heat transfer element 225 is thermally connected to the heater installed on the base station 220, ensuring that heat is transferred from the heater of the base station 220 to the cleaning zone 224, providing the necessary heat energy for the liquid in the cleaning zone.

[0057] To ensure high thermal conductivity and stability, the heat transfer element 225 is selected primarily based on materials with high thermal conductivity and good stability. In this embodiment, aluminum, copper, and other metals are selected as the main constituent materials of the heat transfer element 225. These metals are widely used in the field of heat transfer due to their excellent thermal conductivity, and can effectively transfer heat to the cleaning zone 224, providing the necessary thermal energy support for the self-cleaning of the stirring component.

[0058] In another example of this disclosure, the heat conduction element 225 is part of the body of the rear heating assembly 2262. That is, when designed for assembly, at least a portion of the heat dissipation portion on the body of the rear heating assembly 2262 is located within the cleaning zone and comes into contact with the cleaning element of the surface cleaning device during a self-cleaning cycle or a thermal drying cycle.

[0059] Therefore, the post-heating component 2262 also functions during the self-cleaning process of the surface cleaning device. By transferring heat, the post-heating component 2262 transfers thermal energy to at least a portion of the cleaning area, particularly for heating residual water and clean water within the cleaning area, to more effectively achieve self-cleaning of the agitator. The purpose of this heating effect is to increase the molecular activity of dirt particles while reducing bacterial activity or directly killing bacteria. Specifically, the post-heating component 2262 interacts with the liquid in the cleaning area through the heat conduction element 225, transferring thermal energy to at least a portion of the cleaning area through efficient heat conduction. This includes residual water on the agitator and clean water within the cleaning area. The presence of the heat conduction element increases the temperature of these liquids, thereby activating chemical processes within the cleaning area, such as increased molecular activity and reduced bacterial activity, thus effectively removing residual dirt from the cleaning element during the self-cleaning process.

[0060] Figure 5 A hardware device block diagram 500 is shown for a base station 220 supporting the performance of surface cleaning equipment maintenance according to various aspects of this disclosure. The base station 220 may be a reference... Figures 1 to 5 Examples of various aspects of the described base station 220. Base station 220 may include an AC / DC module, a preheating assembly 2261, a rear heating assembly 2262, a blower 229, an NTC, a MOS, an LDO, etc. Base station 220 may also include a processor. Each of these components can communicate with each other (e.g., via one or more buses).

[0061] The AC / DC module can accept alternating current such as that output from a household power outlet. This current is converted into direct current by the AC / DC module and can be passed to other components of the base station 220 (such as the front heating component 2261, the rear heating component 2262, and the blower 229), as well as to the surface cleaning equipment, which can be charged by the rechargeable battery.

[0062] Base station 220 also includes a processor, such as a general-purpose processor, DSP, CPU, microcontroller, ASIC, FPGA, programmable logic device, discrete gate or transistor logic component, discrete hardware component, or any combination thereof. In some cases, the processor may be configured to use a memory controller to operate the memory array. In other cases, the memory controller may be integrated into the processor. The processor may be configured to execute computer-readable instructions stored in the memory to cause base station 220 to perform various functions (e.g., supporting self-cleaning cycles or thermal drying cycles).

[0063] Base station 220 also includes one or more sensors configured to perform periodic or continuous automatic measurements related to autonomous functions.

[0064] In one example, the processor includes an autonomous management module that can be configured to identify the current state of base station 220 based on received instruction data and to execute self-cleaning and thermal drying cycles based on the identified state. For example, when the surface cleaning device is not located at base station 220, the AC / DC module should disable current supply to the PTC heating component 226. Furthermore, during the self-cleaning cycle, high-power execution phases (e.g., the surface cleaning device's fan operates at high power, and the cleaning component of the surface cleaning device operates at a high speed on base station 220) and low-power execution phases (e.g., the surface cleaning device's fan stops operating, and the cleaning component of the surface cleaning device operates at a low speed on base station 220) are identified to selectively charge the surface cleaning device's rechargeable battery during the low-power phase of the self-cleaning cycle.
