[0002] This application claims priority to Chinese patent application filed on March 17, 2025, with application number 202510312121.8 and entitled "Control Method and Cleaning System for Cleaning System", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of cleaning technology, and in particular to a control method and a cleaning system for a cleaning system. Background Technology

[0004] With the development of science and technology and the improvement of living standards, household cleaning equipment such as floor scrubbers and sweeping and mopping machines have become increasingly popular, reducing the burden of housework.

[0005] Taking a floor scrubber as an example, after completing its cleaning work and returning to its base, the scrubber performs a self-cleaning process. This process for the roller brush includes hot water washing and hot drying stages. In the hot water washing stage, the heating device heats the water used to clean the roller brush. In the hot drying stage, the heating device also heats the airflow from the fan, creating a hot airflow that carries away the moisture from the roller brush, thus drying it. However, the heat generated by the heating device can easily burn the roller brush, and even after the scrubber is removed from its base, the exposed cleaning tank may be too hot, posing a risk of burns. Summary of the Invention

[0006] In view of this, this application provides a control method for a cleaning system and a cleaning system.

[0007] According to a first aspect of the present disclosure, a control method for a cleaning system is provided. The cleaning system includes a cleaning device and a base. The cleaning device includes a body and a floor brush. The floor brush is provided with cleaning components. A suction device is provided inside the body.

[0008] The base is provided with a cleaning tank for placing the cleaning parts, and a heating device and a fan are installed inside the base;

[0009] The control method includes:

[0010] In response to the self-cleaning stop command, the heating device is turned off, and the cleaning system is controlled to perform a heat dissipation action;

[0011] The heat dissipation action includes: controlling the target device to generate airflow and using the airflow to carry away the heat from the base, so as to at least reduce the temperature of the heating device;

[0012] The target device is at least one of the fan and the suction device.

[0013] In the pursuit of ultimate self-cleaning efficiency and effectiveness, many companies have begun to increase the power of heating devices during self-cleaning and drying, so as to achieve high temperature in a short time and quickly achieve self-cleaning and drying.

[0014] However, this leads to uneven drying of the roller brush and waste of energy, and may also cause safety issues.

[0015] Based on this, this application provides a control method that, upon receiving a stop command, performs a heat dissipation action on the base. The heat dissipation action is performed using at least one of the main motor or the fan in the base. When using the main motor for heat dissipation, airflow is mainly drawn from the bottom by suction to achieve heat dissipation. At the same time as heat dissipation, the airflow temperature can also be used to dry the floor scrubber throughout the entire process.

[0016] In other words, by using a suction method, the residual heat temperature is further utilized, while also preventing the heating device on the base from overheating and damaging the roller brush or causing a safety accident.

[0017] On the other hand, the airflow driven by the fan on the base can also utilize the residual heat to further dry the inside of the roller brush, which can also achieve energy utilization and prevent problems caused by the heating device.

[0018] In other words, if the cleaning equipment is not on the base, the fan in the base will be used for heat dissipation, which will also ensure that the heating device on the base dissipates heat quickly and prevent it from burning users who suddenly touch it.

[0019] The stop command is generally the last command in the self-cleaning process, such as the drying stop command. However, it can also be a stop command during other heating processes, such as the hot water self-cleaning stop command. Generally, after the drying stop command is issued, it indicates that self-cleaning is complete. At this point, although the heating device will stop heating, residual heat can still cause localized overheating. In this embodiment, a heat dissipation action is performed after self-cleaning ends. This heat dissipation action can at least reduce the temperature of the heating device, reducing the impact of residual heat on the cleaning components or the bottom wall of the tank. If the cleaning equipment is still on the base after self-cleaning, heat dissipation can prevent the cleaning components from overheating due to residual heat, thus improving the service life of the cleaning components. The reduced temperature of the heating device also reduces the impact of residual heat on the bottom wall of the cleaning tank, preventing burns to people or animals from the exposed bottom wall after the cleaning equipment is removed from the base.

[0020] Airflow can also flow directly over the bottom wall of the tank or the cleaning components, carrying away the heat from the bottom wall or the cleaning components, reducing the temperature of the bottom wall or the cleaning components, and further reducing the risk of overheating of the cleaning components and high temperature of the bottom wall of the tank.

[0021] The heat dissipation action can be performed by the cleaning device (i.e., the main unit heat dissipation action described below), by the base (i.e., the base heat dissipation action described below), or by both the cleaning device and the base. The entities performing the heat dissipation action are diverse, allowing for flexible selection based on different scenarios.

[0022] Optionally, the heat dissipation action includes a main unit heat dissipation action and / or a base heat dissipation action, wherein the main unit heat dissipation action includes: the suction device performing a suction action;

[0023] The heat dissipation action of the base includes: turning on the fan and using the airflow blown out by the fan to at least reduce the temperature of the heating device.

[0024] When the main unit is cooling down, the main unit motor can be turned on to provide power for the suction action. During the drying stage, there is almost no liquid in the cleaning tank. After drying stops, the suction action draws air into the wastewater tank. This airflow can flow through the space between the cleaning parts and the bottom wall of the cleaning tank, carrying away the heat from the cleaning parts and the bottom wall of the tank, thus reducing the temperature of the cleaning parts and the cleaning tank.

[0025] Regarding the heat dissipation action of the base, after the fan is turned on, the airflow generated by the fan can not only remove the residual heat of the heating device and reduce the temperature of the heating device, but also flow over the surface of the cleaning tank, reducing the temperature of the bottom wall of the cleaning tank and the temperature of the cleaning parts.

[0026] Optionally, the control method includes:

[0027] Obtain the location information of the cleaning equipment;

[0028] The heat dissipation action of the self-cleaning system is adjusted according to the location information.

[0029] Location information includes, but is not limited to, whether the cleaning equipment is on the base. If the cleaning equipment is not on the base, the suction device cannot be used for heat dissipation; if the cleaning equipment is on the base, at least one of the suction device and the fan can be used for heat dissipation. Therefore, adjusting the heat dissipation action according to the location information can ensure that the heat dissipation action is accurately matched to different application scenarios and ensures the heat dissipation effect.

[0030] Optionally, adjusting the heat dissipation action of the cleaning system based on the location information includes:

[0031] When the cleaning device is on the base, it at least controls the suction device to perform a main unit heat dissipation action;

[0032] When the cleaning device is not on the base, the fan is controlled to perform heat dissipation on the base.

[0033] Sensors can be used to determine whether the cleaning equipment is on the base. These sensors include, but are not limited to, Hall effect sensors, photoelectric sensors, and ultrasonic sensors.

[0034] Upon receiving a stop command, the system first determines the location information, allowing it to select different heat dissipation methods. This not only dissipates heat but also makes the most of the remaining heat, ensuring safety while maximizing the reuse of thermal energy.

[0035] Specifically, before performing the cooling action, determine whether the cleaning equipment is on the base. Different cooling actions can be performed depending on whether the cleaning equipment is on the base or not. This ensures that the base can be effectively cooled, and a suction device can be used to assist in cooling, which helps to improve the cooling effect. For example, if the cleaning equipment is on the base, both the main unit cooling action and the base cooling action are performed. The main unit cooling action mainly generates airflow above the cleaning tank, which can better dissipate heat from the cleaning components and the top surface of the bottom wall of the cleaning tank. At the same time, the hot airflow can also dry the inside of the main unit, thus achieving full-chain drying. The base cooling action can generate airflow both below and above the cleaning tank, which can better dissipate heat from the heating device and the bottom surface of the bottom wall of the cleaning tank. The combination of the two cooling actions can increase the airflow volume, accelerate airflow turbulence, expand the components that can be cooled, and improve the cooling effect.

[0036] Optionally, adjusting the heat dissipation action of the cleaning system based on the location information includes:

[0037] When the cleaning device is on the base, it detects the temperature of the heating device. If the temperature of the heating device is greater than the preset temperature, it controls the suction device to perform the heat dissipation action of the main unit and the heat dissipation action of the base.

[0038] For example, the preset temperature can be around 45°C. A temperature higher than the preset temperature means a greater risk of overheating of the base or the roller brush, making it more necessary to perform heat dissipation actions. Conversely, a temperature lower than or equal to the preset temperature means a lower risk of overheating of the base or the roller brush, eliminating the need for heat dissipation actions, thus saving energy and avoiding unnecessary energy waste.

[0039] As mentioned earlier, when both the suction device and the fan are activated simultaneously, the suction action of the suction device primarily generates a cooling airflow above the cleaning tank, which better dissipates heat from the cleaning components and the top surface of the tank's bottom wall. Meanwhile, the fan generates cooling airflow both below and above the cleaning tank, better dissipating heat from the heating device and the bottom surface of the tank's bottom wall. The combination of these two cooling actions increases the airflow volume, accelerates airflow turbulence, expands the area of ​​components that can be cooled, and improves the overall cooling effect.

[0040] Optionally, the cleaning component includes a roller brush, and adjusting the heat dissipation action of the cleaning system according to the position information includes:

[0041] When the cleaning device is on the base, it controls the suction device to perform the heat dissipation action of the main unit and the heat dissipation action of the base, and controls the roller brush to rotate.

[0042] For heating devices, the bottom wall of the groove that contacts the cleaning element may be part of the heating device. The roller brush can be ironed using residual heat from the contact with the heating device. For infrared heating devices, the bottom wall of the groove here is specifically a transmitting element. When performing the heat dissipation action, the roller brush is kept rotating. The rotating roller brush can continuously change its contact position with the heating device, which can not only make full use of the residual heat of the heating device to iron the brush bristles, making the brush bristles smoother and drier, but also prevent the roller brush from overheating in some areas.

[0043] For example, when performing the heat dissipation action, the control brush alternately rotates forward or in reverse.

[0044] Optionally, the control method includes: controlling the fan to start for a preset time, and then turning off the fan; or,

[0045] In response to the temperature of the heating device detected by the temperature sensor being less than or equal to a preset temperature, the heat dissipation operation is stopped.

[0046] After the fan has been turned on for a preset time, or when the temperature of the heating device is lower than the preset temperature, it indicates that the temperature of the base or roller brush has dropped to a safe temperature and the heat dissipation action can be stopped.

[0047] Whether performing main unit cooling or base cooling, the system can determine whether to stop cooling based on the temperature of the heating element. For example, if the fan is currently on, and the temperature sensor detects that the heating element's temperature is lower than the preset temperature, the fan can be turned off. If the main unit motor is currently on, and the heating element's temperature is detected to be lower than the preset temperature, the main unit motor can be turned off to stop the suction operation.

[0048] Optionally, the preset time is 2-5 minutes, and the preset temperature is 40-50℃.

[0049] When the fan has been running for 2-5 minutes, or when the temperature of the heating device is below 40-50℃, the temperature of the cleaning parts and the bottom wall of the tank has dropped to a safe temperature. At this point, stopping the heat dissipation action can balance heat dissipation effect and energy consumption.

[0050] Optionally, in the host heat dissipation mode, the suction power of the suction device is lower than the operating power of the suction device during the cleaning process of the cleaning equipment.

[0051] During the cleaning process, the suction action of the cleaning equipment aims to remove dirt from the floor. Dirt may include sewage, or solid dirt such as hair, particles, and lumps. A relatively large power is required to ensure that the dirt is completely removed. However, the suction action is used to generate cooling airflow, which requires less power to achieve the same purpose. This reduces energy consumption and noise.

[0052] Optionally, the base further includes an air duct and a heat dissipation component located within the air duct, the heat dissipation component being located below the heating device;

[0053] The heat dissipation action of the base includes: the airflow blown by the fan flows through the heat dissipation component.

[0054] Based on the foregoing description, by using a heat sink to absorb the heat emitted by the infrared emitter, and then using a fan to blow air onto the heat sink, the heat generated by the heat source can be reduced or even avoided from becoming too concentrated. During the heat dissipation process, the heating device is in the off state. The airflow blown by the fan carries away the heat from the heat sink, which is beneficial for heat dissipation. In addition, the airflow blown by the fan also passes over the cleaning tank, which is beneficial for carrying away the heat from the bottom wall of the cleaning tank and the cleaning components.

[0055] Optionally, the air outlet of the air duct can be directed toward the bottom wall of the cleaning tank, and the heat dissipation action of the base includes: the airflow blown by the fan blows toward the bottom wall of the tank through the air outlet of the air duct, so as to reduce the temperature of the bottom wall of the tank.

[0056] In existing technologies, the air outlet of the air duct faces the periphery of the roller brush. After the airflow generated by the fan flows through the air duct to the air outlet, most of it is blown towards the cleaning parts, and almost none of it is blown towards the bottom wall of the tank. In this embodiment of the present disclosure, since the heating device is located below the cleaning tank, the temperature above the cleaning tank is higher. By changing the air outlet to face the bottom wall of the tank, the airflow velocity towards the cleaning tank can be faster and the flow rate can be larger, which is beneficial to further improve the cooling effect on the bottom wall of the tank.

[0057] Optionally, the air outlet faces the bottom wall of the trough, or the orientation of the air outlet is adjustable within a preset angle range, and the preset angle range includes the angle at which the air outlet faces the bottom wall of the trough.

[0058] Compared to existing technologies, the air outlet position can be moved downwards, closer to the bottom wall of the tank. The airflow from the outlet can flow along the bottom wall of the tank towards the machine body, improving the heat dissipation effect on the bottom wall of the tank.

[0059] For example, the base includes a baffle located above the bottom wall of the tank. The baffle forms an air outlet. The baffle can be a plate fixedly mounted on the front edge of the base, in which case the air outlet is fixedly facing the bottom wall of the tank. Alternatively, the baffle can be movably mounted on the front edge of the base. For example, the baffle can be rotatably mounted on the front edge of the base via a pivot. An additional rotating motor and transmission structure can be provided. The rotating motor drives the baffle to rotate through the transmission structure. As the baffle rotates, the direction of the air outlet changes. Specifically, when the baffle rotates downwards, the direction of the air outlet gradually decreases until the air outlet faces the bottom wall of the tank; when the baffle rotates upwards, the direction of the air outlet can be raised.

[0060] Optionally, the heating device includes an infrared heating device, which includes an infrared emitter and a transmitting element, both located below the roller brush. The infrared rays emitted by the infrared emitter at least partially pass through the transmitting element and radiate to the cleaning element.

[0061] As mentioned above, when the heating device is an infrared heating device, the temperature of the bottom wall of the tank is more likely to be too high, and the cleaning parts are also more likely to overheat. The control method of the present disclosure is particularly suitable for heat dissipation of the base using an infrared heating device.

[0062] According to a second aspect of the present disclosure, a control method for a cleaning system is provided. The cleaning system includes a cleaning device and a base. The cleaning device includes a body and a floor brush. The floor brush is provided with cleaning components. A suction device is provided inside the body.

[0063] The base is provided with a cleaning tank for placing the cleaning parts, and a heating device and a fan are installed inside the base;

[0064] The control method includes:

[0065] In response to the self-cleaning stop command, determine whether the self-cleaning action performed includes a heating action;

[0066] If the self-cleaning action performed includes a heating action, control the cleaning system to perform a heat dissipation action.

[0067] During the self-cleaning process on the base, the cleaning device may stop in two ways:

[0068] One type of stop is a normal shutdown after self-cleaning is complete. When the stop command is issued, self-cleaning is finished, and the self-cleaning actions generally include heating. The other type is a self-cleaning interruption stop command, such as in the event of an unexpected power outage or user-mandated forced shutdown. In these situations, the cleaning equipment may not have completed the self-cleaning process. Furthermore, after receiving a self-cleaning command, it's possible that hot water self-cleaning or drying operations haven't been performed yet, or only room temperature water washing or lukewarm water washing has been performed. In this case, cooling operations may not be necessary.

[0069] It is understandable that the heating process involves temperatures above 45°C. For example, the hot water temperature in a self-cleaning system is 60°C, 80°C, or even 100°C, the heating device has been turned on, and the temperature of the heating device is greater than 45°C, etc.

[0070] The system determines whether to perform a cooling action based on whether the self-cleaning process includes heating. If the self-cleaning process does not include heating, the cleaning system will not perform a cooling action. This reduces unnecessary cooling, lowers energy consumption, and improves the user experience.

[0071] It should also be noted that if there is still liquid in the cleaning tank when the self-cleaning stops (this liquid may be the cleaning liquid just sprayed out by the water distributor, or it may be dirt), then when the host is cooling down, the suction action can be performed multiple times. The suction action will first remove the liquid in the cleaning tank, and then generate a cooling airflow to cool the cleaning tank.

[0072] Optionally, the stop command includes a self-cleaning interrupt stop command.

[0073] For example, if the drying stop command is the last action command of the self-cleaning process, then the self-cleaning interruption stop command can be a stop self-cleaning command received before the drying stop command.

[0074] If the stop command is a self-cleaning interruption stop command preceding the last self-cleaning action command, it is necessary to first determine whether the executed self-cleaning actions include heating actions, and then determine whether to execute the cooling action based on the determination result. If the stop command is a stop command following the last self-cleaning action command, it indicates that self-cleaning has been completed. In this case, there is no need to determine whether the executed self-cleaning actions include heating actions, and the cooling action can be executed directly, which is conducive to timely response to the cooling action and reduces unnecessary resource waste.

[0075] Optionally, the heating action includes at least one of the following: hot water self-cleaning action, drying action, or ironing action.

[0076] The hot water temperature for self-cleaning can be above 45℃. Ironing refers to the action of ironing the cleaning part by contacting the heat exchanger or heating device with the cleaning part. Generally, as long as the heating device has been turned on for a period of time, it is considered that an ironing action has been performed.

[0077] The cleaning system only initiates heat dissipation when the self-cleaning process includes heating. This reduces unnecessary heat dissipation, lowers energy consumption, and improves the user experience.

[0078] According to a third aspect of the present disclosure, a control method for a cleaning system is provided. The cleaning system includes a cleaning device and a base. The cleaning device includes a body and a floor brush. The floor brush is provided with cleaning components. A suction device is provided inside the body. The base is provided with a cleaning tank for placing the cleaning components. A heating device and a fan are provided inside the base.

[0079] The control method includes:

[0080] In response to a self-cleaning stop command, the temperature of the heating device is determined;

[0081] If the temperature of the heating device is higher than the preset temperature, the cleaning system is controlled to perform a heat dissipation action.

[0082] Regardless of whether the entire self-cleaning process is complete, once self-cleaning stops, the system can determine whether to perform a cooling action based on the temperature of the heating element. If the temperature of the heating element is less than or equal to the preset temperature, the cleaning system can be controlled not to perform a cooling action. This reduces unnecessary cooling actions. For example, during the self-cleaning process, if the cleaning parts are found to be only lightly soiled, a higher hot water temperature is unnecessary, and the drying temperature is also low. In such cases, although the heating element is activated during the self-cleaning process and overheating occurs, the low temperature minimizes the possibility of overheating or burns. In these situations, no cooling action is required, reducing energy consumption and improving the user experience.

[0083] Optionally, the heating device includes an infrared heating device, which includes an infrared emitter, a transmitting element, and a reflecting element. The transmitting element is located below the cleaning element, and the infrared emitter is located below the transmitting element. The reflecting element and the transmitting element together form a cavity. The infrared emitter and the temperature sensor are both located within the cavity. The temperature sensor uses the detected air temperature near the infrared emitter as the temperature of the heating device.

[0084] The temperature detector measures the temperature of the air, which is relatively low, rather than directly measuring the temperature of the infrared emitter or transmissive element, which helps to reduce damage to the temperature sensor.

[0085] According to a fourth aspect of the present disclosure, a cleaning system is provided, the cleaning system including a cleaning device, a base, and a controller;

[0086] The controller is configured to perform the control method of the cleaning system as described in any of the embodiments of the first, second, or third aspects described above.

[0087] The cleaning system provided in this embodiment has the same technical effects as the aforementioned control method, and will not be described again here. Attached Figure Description

Detailed Implementation

[0094] To make the technical solution and beneficial effects of this application more apparent and understandable, a detailed description is provided below by listing specific embodiments. The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application pertains.

[0095] This disclosure is not exhaustive, but merely illustrative of some embodiments, and is not intended to limit the scope of protection of this disclosure. Unless otherwise specified, each step in a particular embodiment can be implemented as an independent embodiment, and the steps can be arbitrarily combined. For example, a solution after removing some steps in a particular embodiment can also be implemented as an independent embodiment, and the order of the steps in a particular embodiment can be arbitrarily interchanged. Furthermore, the optional implementation methods in a particular embodiment can be arbitrarily combined; moreover, the embodiments can be arbitrarily combined, for example, some or all steps of different embodiments can be arbitrarily combined, and a particular embodiment can be arbitrarily combined with the optional implementation methods of other embodiments.

[0096] In each of the disclosed embodiments, unless otherwise specified or in case of logical conflict, the terminology and / or descriptions of the embodiments are consistent and can be referenced by each other. Technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.

[0097] The terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the scope of this disclosure.

[0098] The control method of this embodiment is applied to a cleaning system. The cleaning system will be described in detail below with reference to Figures 1 to 5.

[0099] As shown in Figure 1, the cleaning system 10 includes a cleaning device 100 and a base 200. The cleaning device 100 may include a body and a floor brush. During operation, the cleaning device 100 moves on the surface to be cleaned, and the floor brush contacts and rubs against the surface to be cleaned to clean it.

[0100] Referring to Figure 1, the floor brush may include a housing 103 and a cleaning component. The housing serves as the main support structure for the floor brush, and the cleaning component can be mounted on the housing 103. The floor brush can move the cleaning component across the surface to be cleaned, and the cleaning component completes the cleaning work by contacting the surface. The cleaning component may be a conveyor belt or a roller brush 110, etc., and the surface to be cleaned includes, but is not limited to, floors, carpets, and walls. Cleaning equipment includes, but is not limited to, floor scrubbers, electric mops, and combined floor scrubbers and mops. For ease of description, the cleaning system 10 will be described below using a floor scrubber as the cleaning equipment, a roller brush 110 as the cleaning component, and a floor as the surface to be cleaned as an example.

[0101] When the cleaning equipment is cleaning, the roller brush 110 contacts the ground. The roller brush 110 is driven to rotate at high speed by the roller brush motor installed in the base 200, so that the roller brush 110 can make friction contact with the ground to clean the ground.

[0102] The floor brush may also include a traveling wheel 102, which contacts the ground and rolls along the ground to assist the cleaning equipment in moving on the ground and improve the stability of the floor brush when moving on the ground.

[0103] Along the direction of travel of the floor brush, the roller brush 110 can be installed at the front end of the housing, and the traveling wheel 102 can be installed at the rear end of the housing. This facilitates control of the direction of travel of the floor brush and helps maintain the balance of the floor brush during travel. Moreover, the roller brush 110 preferentially contacts the surface to be cleaned, and the front of the roller brush 110 is unobstructed, which is beneficial for the roller brush 110 to clean the surface to be cleaned.

[0104] The cleaning equipment may also include a main body, with a floor brush rotatably attached to the bottom of the main body. During cleaning, the user can hold the main body and swing it to rotate the floor brush relative to the main body, allowing the floor brush to travel to different areas (e.g., under tables, under cabinets, etc.) so that the floor brush can clean different areas.

[0105] Referring to Figure 1, the machine body can be equipped with components such as a clean water tank 101 and a wastewater tank. The clean water tank 101 holds the cleaning liquid. When the cleaning equipment is working, the clean water tank 101 provides cleaning liquid (including but not limited to the cleaning water used to clean the roller brush in the cleaning tank during the self-cleaning process) to the roller brush 110 to wet it. This allows the roller brush 110 to wet the stains on the floor during the cleaning process, reducing the adhesion of the stains and making it easier to remove them from the surface to be cleaned. Wastewater (along with particles, hair, and other foreign objects) on the floor is sucked into the wastewater tank, thus completing the cleaning process.

[0106] The machine body may include a suction device, which includes, but is not limited to, a suction motor. The suction device can perform a suction action to draw dirt near the roller brush 110 into the wastewater tank.

[0107] After the cleaning equipment is placed back on the base, auxiliary operations such as self-cleaning and charging of the cleaning equipment are performed.

[0108] The execution entity in this embodiment can be a controller installed in the cleaning device, a controller installed in the base, or a server corresponding to the cleaning device and the base. This server is located in the cloud, connected to the cleaning device via a network, and issues control commands to the cleaning device and the base, or forwards control commands sent by the user through a terminal device (such as a mobile phone, wearable device, or computer) to the cleaning device and the base.

[0109] The controller described above may include a microcontroller unit (MCU). Of course, the controller may also include other devices capable of control functions.

[0110] As shown in Figure 2, the base 200 is provided with a cleaning tank 211 for placing the roller brush 110. When the cleaning device 100 is parked on the base 200, the cleaning device 100 can perform self-cleaning. During the self-cleaning process, the roller brush 110 is cleaned and dried in the cleaning tank 211.

[0111] The cleaning system also includes a heating device located within the base 200. The heating device may include a PTC (Positive Temperature Coefficient) heating element, a resistance wire, or an infrared heating device, etc.

[0112] After cleaning, floor scrubbers often perform self-cleaning. In some implementations, PTC or heating wires can be used to directly heat hot water for cleaning. In addition, a separate heating wire can be added to heat the airflow blown by a fan for drying.

[0113] In other implementations, both hot water self-cleaning and hot drying can be achieved using an infrared heating device.

[0114] For example, as shown in Figure 2, the infrared heating device includes a transmitting element 230 and an infrared emitter 220, both located below the roller brush 110. The transmitting element 230 can transmit infrared rays. The infrared emitter 220 can emit infrared rays, and at least a portion of the infrared heat emitted by the infrared emitter 220 can be radiated to the roller brush 110 through the transmitting element 230. Infrared rays have strong penetrating power. When the infrared emitter 220 is turned on, at least a portion of the infrared light generated by the infrared emitter 220 passes through the transmitting element 230 and irradiates the roller brush. A portion of the infrared light penetrates the brush bristles and irradiates the inside of the bristles, generating radiant heat inside the bristles, thus drying the brush bristles from the inside out.

[0115] For example, the infrared emitter 220 can be a carbon fiber heating tube. When the infrared emitter 220 is turned on, current can be supplied to the carbon fiber heating tube. The current passes through the carbon fiber heating tube, causing the molecules inside the carbon fiber heating tube to move, thereby converting electrical energy into heat energy. This heat energy can be rapidly and uniformly radiated to the area around the roller brush 110 in the form of infrared radiation to dry the roller brush 110.

[0116] When infrared light penetrates the transmissive element, the element absorbs a portion of the infrared light, converting it into heat and raising its temperature. The heated transmissive element can then conduct this heat to the cleaning liquid in the cleaning tank above it. In some implementations, the cleaning element (e.g., roller brush 110) contacts the transmissive element 230. The transmissive element 230 can "iron" the roller brush 110 through contact, further improving drying efficiency and making the bristles smoother. Therefore, infrared light can provide a uniform heat distribution, effectively reducing or preventing localized overheating or undrying of the roller brush 110, thus significantly improving drying quality.

[0117] In some embodiments, the infrared heating device may further include a reflector 240, with the reflector 240 and the transmitter 230 located on opposite sides of the infrared emitter 220 in a vertical direction, and a heat sink 290 located below the reflector 240. At least a portion of the infrared radiation can be reflected by the reflector 240 to the transmitter 230 and radiated to the roller brush 110 through the transmitter 230. For example, the side of the reflector 240 facing the infrared emitter 220 can be a mirror surface so that infrared radiation projected onto the mirror surface of the reflector 240 can be reflected.

[0118] For example, infrared rays generated by the side of the infrared emitter 220 facing the roller brush 110 can be projected onto the transmissive element 230 and then onto the roller brush 110. Infrared rays generated by the side of the infrared emitter 220 facing away from the roller brush 110 can be projected onto the reflective element 240 and reflected onto the transmissive element 230, thereby being projected onto the roller brush 110 through the transmissive element 230 to dry the roller brush 110.

[0119] By reflecting infrared rays through the reflector 240, the infrared rays emitted by the side of the infrared emitter 220 facing away from the roller brush 110 can also be projected onto the roller brush 110 to dry it. This effectively increases the amount of infrared rays projected onto the roller brush 110, effectively reducing or avoiding infrared ray waste. This significantly improves the utilization rate of infrared rays and enhances the cleaning and drying efficiency of the roller brush 110 by the base 200.

[0120] In some alternative embodiments, the infrared heating device further includes a heat sink 290 located below the infrared emitter 220. The heat sink 290 can absorb some of the energy from the infrared emitter 220, reducing the temperature near the infrared emitter 220, effectively ensuring the service life of the base components, and preventing excessive heat concentration from causing potential risks.

[0121] In some optional embodiments, as shown in FIG2, the base further includes an air duct and a heat sink 290 located within the air duct, the heat sink 290 being positioned below the infrared emitter 220. The heat sink 290 can absorb some of the energy from the infrared emitter 220, reducing the temperature near the infrared emitter 220, effectively ensuring the service life of the base components, and preventing excessive heat concentration from causing potential hazards. The airflow from the fan is heated after passing through the heat sink 290 before being blown into the cleaning tank, achieving heat convection drying of the roller brush 110.

[0122] Compared to other heating methods, infrared heating devices utilize emitted infrared rays to achieve heating through multiple means such as thermal radiation, thermal sensing, and thermal convection. This results in more uniform heating and faster heating of the roller brush and cleaning liquid. However, it is also more likely to cause higher temperatures in the roller brush or components near the heating device (such as the transmissive element 230).

[0123] For example, the transmissive element 230 is a glass panel, often forming part of the bottom wall of the cleaning tank. After the cleaning equipment is separated from the base, the transmissive element 230 is often exposed. The temperature of the back of the transmissive element 230, facing away from the roller brush 110, can reach 200-280℃. This temperature is higher than that of other heating methods such as PTC and resistance wire, making it more prone to overheating of the roller brush 110. The exposed transmissive element 230 is also more likely to burn people or animals. Therefore, one of the inventive concepts of this application is to perform a heat dissipation action after self-cleaning is completed to reduce the temperature of the heating device, transmissive element, or roller brush, thereby reducing or even avoiding overheating damage to the roller brush 110 and improving the safety of the base.

[0124] The control method of this application will be described below with reference to Figures 1 to 5, taking the controller in the cleaning equipment as an example.

[0125] For example, the base 200 has a signal input / output interface. When the cleaning device 100 is placed on the base 200, the signal interface of the cleaning device 100 is electrically connected to the signal input / output interface of the base 200. The user can operate the self-cleaning button on the cleaning device 100 to send a self-cleaning command to the controller. The controller turns on the infrared transmitter based on the self-cleaning command and controls the corresponding components on the cleaning device and the base to perform self-cleaning or heat dissipation actions.

[0126] For example, the base may also include a wireless communication module, which can receive instructions from the controller, cloud, or terminal device in the cleaning equipment. This allows the base to perform heat dissipation actions based on the received instructions after the cleaning equipment leaves the base. Alternatively, the base may also include a controller, allowing it to perform heat dissipation actions as needed.

[0127] Example 1

[0128] The control method provided in Example 1 is used for a cleaning system. Based on the foregoing description, the cleaning system includes a cleaning device and a base. The cleaning device includes a body and a floor brush. The floor brush is equipped with cleaning components, and the body is equipped with a suction device. The base is equipped with a cleaning tank for placing the cleaning components, and the base is equipped with a heating device and a fan.

[0129] As shown in Figure 3, the control method of Embodiment 1 includes step S10: in response to the self-cleaning stop command, the heating device is turned off, and the cleaning system is controlled to perform heat dissipation action; the heat dissipation action includes: controlling the target device to generate airflow, and using the airflow to remove the heat from the base, so as to at least reduce the temperature of the heating device.

[0130] For example, the suction device may include a main motor.

[0131] In the pursuit of ultimate self-cleaning efficiency and effectiveness, many companies have begun to increase the power of heating devices during self-cleaning and drying, so as to achieve high temperature in a short time and quickly achieve self-cleaning and drying.

[0132] However, this leads to uneven drying of the roller brush and waste of energy, and may also cause safety issues.

[0133] Based on this, this application provides a control method that, upon receiving a stop command, performs a heat dissipation action on the base. The heat dissipation action is performed using at least one of the main motor or the fan in the base. When using the main motor for heat dissipation, airflow is mainly drawn from the bottom by suction to achieve heat dissipation. At the same time as heat dissipation, the airflow temperature can also be used to dry the floor scrubber throughout the entire process.

[0134] In other words, by using a suction method, the residual heat temperature is further utilized, while also preventing the heating device on the base from overheating and damaging the roller brush or causing a safety accident.

[0135] On the other hand, the airflow driven by the fan on the base can also utilize the residual heat to further dry the inside of the roller brush, which can also achieve energy utilization and prevent problems caused by the heating device.

[0136] In other words, if the cleaning equipment is not on the base, the fan in the base will be used for heat dissipation, which will also ensure that the heating device on the base dissipates heat quickly and prevent it from burning users who suddenly touch it.

[0137] The stop command is generally the last command in the self-cleaning process, such as the drying stop command. However, it can also be a stop command during other heating processes, such as the hot water self-cleaning stop command. Generally, after the drying stop command is issued, it indicates that self-cleaning is complete. At this point, although the heating device will stop heating, residual heat can still cause localized overheating. In this embodiment, a heat dissipation action is performed after self-cleaning ends. This heat dissipation action can at least reduce the temperature of the heating device, reducing the impact of residual heat on the cleaning components or the bottom wall of the tank. If the cleaning equipment is still on the base after self-cleaning, heat dissipation can prevent the cleaning components from overheating due to residual heat, thus improving the service life of the cleaning components. The reduced temperature of the heating device also reduces the impact of residual heat on the bottom wall of the cleaning tank, preventing burns to people or animals from the exposed bottom wall after the cleaning equipment is removed from the base.

[0138] Airflow can also flow directly over the bottom wall of the tank or the cleaning components, carrying away the heat from the bottom wall or the cleaning components, reducing the temperature of the bottom wall or the cleaning components, and further reducing the risk of overheating of the cleaning components and high temperature of the bottom wall of the tank.

[0139] The heat dissipation action can be performed by the cleaning device (i.e., the main unit heat dissipation action described below), by the base (i.e., the base heat dissipation action described below), or by both the cleaning device and the base. The entities performing the heat dissipation action are diverse, allowing for flexible selection based on different scenarios.

[0140] In some alternative embodiments, the heat dissipation action includes a main unit heat dissipation action, a base heat dissipation action, or both a main unit heat dissipation action and a base heat dissipation action. The main unit heat dissipation action includes: the suction device performing a suction action; the base heat dissipation action includes: turning on the fan and using the airflow blown by the fan to at least reduce the temperature of the heating device.

[0141] When the main unit is cooling down, the main unit motor can be turned on to provide power for the suction action. During the drying stage, there is almost no liquid in the cleaning tank. After drying stops, the suction action draws air into the wastewater tank. This airflow can flow through the space between the cleaning parts and the bottom wall of the cleaning tank, carrying away the heat from the cleaning parts and the bottom wall of the tank, thus reducing the temperature of the cleaning parts and the cleaning tank.

[0142] Regarding the heat dissipation action of the base, after the fan is turned on, the airflow generated by the fan can not only remove the residual heat of the heating device and reduce the temperature of the heating device, but also flow over the surface of the cleaning tank, reducing the temperature of the bottom wall of the cleaning tank and the temperature of the cleaning parts.

[0143] Without limitation, the drying stop command can be a command generated by the cleaning equipment or base, or a command received by the cleaning equipment or base from a server, terminal device, or button, touch control, etc. on the machine body.

[0144] In some alternative embodiments, the control method includes:

[0145] S20. Obtain the location information of the cleaning equipment;

[0146] S30. Adjust the heat dissipation action of the self-cleaning system according to the location information.

[0147] Upon receiving a stop command, the system first determines the location information, allowing it to select different heat dissipation methods. This not only dissipates heat but also makes the most of the remaining heat, ensuring safety while maximizing the reuse of thermal energy.

[0148] Location information includes, but is not limited to, whether the cleaning equipment is on the base. If the cleaning equipment is not on the base, the suction device cannot be used for heat dissipation; if the cleaning equipment is on the base, at least one of the suction device and the fan can be used for heat dissipation. Therefore, adjusting the heat dissipation action according to the location information can ensure that the heat dissipation action is accurately matched to different application scenarios and ensures the heat dissipation effect.

[0149] In some implementations, sensor detection can be used to determine whether the cleaning equipment is on the base. These sensors include, but are not limited to, Hall effect sensors, photoelectric sensors, ultrasonic sensors, and vision sensors.

[0150] Without limitation, step S20 can be performed after the cleaning system generates or receives a drying stop command and before the heat dissipation action is performed.

[0151] In some alternative embodiments, the aforementioned step S30 includes:

[0152] Step S31: When the cleaning equipment is on the base, at least control the suction device to perform the main unit heat dissipation action;

[0153] Step S32: When the cleaning equipment is not on the base, control the fan to perform the base heat dissipation action.

[0154] Before initiating cooling actions, determine whether the cleaning equipment is on the base. Different cooling actions can be performed depending on whether the equipment is on or off the base. This ensures effective cooling of the base while also utilizing a suction device to assist in cooling, thus improving the cooling effect. For example, if the cleaning equipment is on the base, both main unit cooling and base cooling actions are performed. The main unit cooling action primarily generates airflow above the cleaning tank, which better dissipates heat from the cleaning components and the top and bottom walls of the cleaning tank. Simultaneously, the hot airflow also dries the internal components of the main unit, achieving end-to-end drying. The base cooling action generates airflow both below and above the cleaning tank, better dissipating heat from the heating device and the bottom wall of the cleaning tank. Combining these two cooling actions increases the airflow volume, accelerates airflow turbulence, expands the area of ​​components that can be cooled, and improves the overall cooling effect.

[0155] In some optional embodiments, the aforementioned step S30: when the cleaning device is on the base, the temperature of the heating device is detected. If the temperature of the heating device is greater than the preset temperature, the suction device is controlled to perform the main unit heat dissipation action and the base heat dissipation action.

[0156] For example, the preset temperature can be around 45°C. A temperature higher than the preset temperature means a greater risk of overheating of the base or the roller brush, making it more necessary to perform heat dissipation actions. Conversely, a temperature lower than or equal to the preset temperature means a lower risk of overheating of the base or the roller brush, eliminating the need for heat dissipation actions, thus saving energy and avoiding unnecessary energy waste.

[0157] As mentioned earlier, when both the suction device and the fan are activated simultaneously, the suction action of the suction device primarily generates a cooling airflow above the cleaning tank, which better dissipates heat from the cleaning components and the top surface of the tank's bottom wall. Meanwhile, the fan generates cooling airflow both below and above the cleaning tank, better dissipating heat from the heating device and the bottom surface of the tank's bottom wall. The combination of these two cooling actions increases the airflow volume, accelerates airflow turbulence, expands the area of ​​components that can be cooled, and improves the overall cooling effect.

[0158] In some optional embodiments, the cleaning component includes a roller brush, and the aforementioned step S30 includes: when the cleaning device is on the base, controlling the suction device to perform a main unit cooling action and a base cooling action, and controlling the roller brush to rotate. Of course, this step can also be combined with the temperature of the heating device for heat dissipation. For example, when the cleaning device is on the base, the temperature of the heating device is detected. If the temperature of the heating device is higher than a preset temperature, controlling the suction device to perform a main unit cooling action and a base cooling action, and controlling the roller brush to rotate.

[0159] For heating devices, the bottom wall of the groove that contacts the cleaning element may be part of the heating device. The roller brush can be ironed using residual heat from the contact with the heating device. For infrared heating devices, the bottom wall of the groove here is specifically a transmitting element. When performing the heat dissipation action, the roller brush is kept rotating. The rotating roller brush can continuously change its contact position with the heating device, which can not only make full use of the residual heat of the heating device to iron the brush bristles, making the brush bristles smoother and drier, but also prevent the roller brush from overheating in some areas.

[0160] For example, when performing the heat dissipation action, the control brush alternately rotates forward or in reverse.

[0161] The reverse rotation of the roller brush lifts the bristles, allowing heat to be transferred more easily to the inside of the brush, thus improving drying efficiency. The forward rotation, on the other hand, uses contact between the brush and the heat-transmitting element to iron the bristles, ensuring a smoother finish. Therefore, alternating forward and reverse rotation reduces the risk of the brush being damaged by heat while improving drying efficiency and effectiveness. Furthermore, the final movement before the brush stops can be configured as a forward rotation, at which point the bristles are relatively soft, ensuring a smoother finish.

[0162] In some alternative embodiments, the control method includes: turning off the fan after the fan has been turned on for a preset time; or, stopping the heat dissipation action in response to the temperature of the heating device detected by the temperature sensor being lower than a preset temperature.

[0163] After the fan has been turned on for a preset time, or when the temperature of the heating device is less than or equal to the preset temperature, it indicates that the temperature of the base or roller brush has dropped to a safe temperature and the heat dissipation action can be stopped.

[0164] Whether performing main unit cooling or base cooling, the system can determine whether to stop cooling based on the temperature of the heating element. For example, if the fan is currently on, and the temperature sensor detects that the heating element's temperature is lower than the preset temperature, the fan can be turned off. If the main unit motor is currently on, and the heating element's temperature is detected to be lower than the preset temperature, the main unit motor can be turned off to stop the suction operation.

[0165] In some implementations, the preset time is 2-5 minutes. For example, the fan is controlled to turn off after 2, 3, 4, or 5 minutes of operation.

[0166] In some implementations, the preset temperature is 40-50℃. For example, when the temperature of the heating device is detected to be 45℃ or lower, the fan or main motor is turned off.

[0167] When the fan has been running for 2-5 minutes, or when the temperature of the heating device is below 40-50℃, the temperature of the cleaning parts and the bottom wall of the tank has dropped to a safe temperature. At this point, stopping the heat dissipation action can balance heat dissipation effect and energy consumption.

[0168] Referring to Figure 2, in some optional embodiments, the heating device is an infrared heating device, which includes an infrared emitter 220, a transmissive element 230, and a reflective element 240. The transmissive element 230 is located below the cleaning element, and the infrared emitter 220 is located below the transmissive element 230. The reflective element 240 and the transmissive element 230 together form a chamber 241. The infrared emitter 220 and the temperature sensor 202 are both located in the chamber 241. The temperature sensor 202 uses the detected air temperature near the infrared emitter 220 as the temperature of the heating device.

[0169] The temperature sensor 202 detects the lower temperature of the air, rather than directly detecting the higher temperature of the infrared emitter or transducer 230, which helps to reduce damage to the temperature sensor 202.

[0170] For example, temperature sensor 202 is an NTC (Negative Temperature Coefficient Sensor). But it is not limited to this.

[0171] In some alternative embodiments, in the host cooling mode, the suction power of the suction device is lower than the operating power of the suction device during the cleaning process of the cleaning equipment.

[0172] During the cleaning process, the suction action of the cleaning equipment aims to remove dirt from the floor. Dirt may include sewage, or solid dirt such as hair, particles, and lumps. A relatively large power is required to ensure that the dirt is completely removed. However, the suction action is used to generate cooling airflow, which requires less power to achieve the same purpose. This reduces energy consumption and noise.

[0173] For example, in host cooling mode, the suction power of the suction device is approximately 5W.

[0174] In some alternative embodiments, the base further includes an air duct and a heat sink located within the air duct, with the heat sink located below the heating device; the heat dissipation action of the base includes: airflow blown out by the fan flowing through the heat sink.

[0175] Based on the foregoing description, by using a heat sink to absorb the heat emitted by the infrared emitter, and then using a fan to blow air onto the heat sink, the heat generated by the heat source can be reduced or even avoided from becoming too concentrated. During the heat dissipation process, the heating device is in the off state. The airflow blown by the fan carries away the heat from the heat sink, which is beneficial for heat dissipation. In addition, the airflow blown by the fan also passes over the cleaning tank, which is beneficial for carrying away the heat from the bottom wall of the cleaning tank and the cleaning components.

[0176] In some alternative embodiments, as shown in FIG2, the air outlet 271 of the air duct 270 can be directed toward the bottom wall of the cleaning tank 211, and the heat dissipation action of the base 200 includes: the airflow blown out by the fan 250 is blown toward the bottom wall of the tank through the air outlet 271 of the air duct 270 to reduce the temperature of the bottom wall of the tank.

[0177] In existing technologies, the air outlet of the air duct faces the periphery of the roller brush. After the airflow generated by the fan flows through the air duct to the air outlet, most of it is blown towards the cleaning parts, and almost none of it is blown towards the bottom wall of the tank. In this embodiment of the present disclosure, since the heating device is located below the cleaning tank, the temperature above the cleaning tank is higher. By changing the air outlet to face the bottom wall of the tank, the airflow velocity towards the cleaning tank can be faster and the flow rate can be larger, which is beneficial to further improve the cooling effect on the bottom wall of the tank.

[0178] In some alternative embodiments, the air outlet faces the bottom wall of the trough, or the orientation of the air outlet is adjustable within a preset angle range, and the preset angle range includes the angle at which the air outlet faces the bottom wall of the trough.

[0179] The preset angle indicates the angle between the center of the air vent and the horizontal plane. The preset angle can be from -5° to 60°, but is not limited to this.

[0180] For example, as shown in Figure 2, compared with the prior art, the position of the air outlet can be moved down and closer to the bottom wall of the tank. The airflow from the air outlet can flow along the bottom wall of the tank towards the direction of the machine body, thereby improving the heat dissipation effect on the bottom wall of the tank.

[0181] For example, the base includes a baffle located above the bottom wall of the tank. The baffle forms an air outlet. The baffle can be a plate fixedly mounted on the front edge of the base, in which case the air outlet is fixedly facing the bottom wall of the tank. Alternatively, the baffle can be movably mounted on the front edge of the base. For example, the baffle can be rotatably mounted on the front edge of the base via a pivot. An additional rotating motor and transmission structure can be provided. The rotating motor drives the baffle to rotate through the transmission structure. As the baffle rotates, the direction of the air outlet changes. Specifically, when the baffle rotates downwards, the direction of the air outlet gradually decreases until the air outlet faces the bottom wall of the tank; when the baffle rotates upwards, the direction of the air outlet can be raised.

[0182] In some alternative embodiments, the heating device includes an infrared heating device, which includes an infrared emitter and a transducer, both located below the roller brush. The infrared rays emitted by the infrared emitter at least partially pass through the transducer and radiate to the cleaning component.

[0183] As mentioned above, when the heating device is an infrared heating device, the temperature of the bottom wall of the tank is more likely to be too high, and the cleaning parts are also more likely to overheat. The control method of the present disclosure is particularly suitable for heat dissipation of the base using an infrared heating device.

[0184] Example 2

[0185] Example 2 provides a control method for a cleaning system. The cleaning system includes a cleaning device and a base. The cleaning device includes a body and a floor brush. The floor brush is equipped with cleaning components. The body is equipped with a suction device. The base is equipped with a cleaning tank for placing the cleaning components. The base is equipped with a heating device and a fan.

[0186] As shown in Figure 4, the control method of Embodiment 2 includes the following steps:

[0187] S110. In response to the self-cleaning stop command, determine whether the self-cleaning action performed includes a heating action;

[0188] S120. If the self-cleaning action already performed includes a heating action, control the cleaning system to perform a heat dissipation action.

[0189] During the self-cleaning process on the base, the cleaning device may stop in two ways:

[0190] One type of stop is a normal shutdown after self-cleaning is complete. When the stop command is issued, self-cleaning is finished, and the self-cleaning actions generally include heating. The other type is a self-cleaning interruption stop command, such as in the event of an unexpected power outage or user-mandated forced shutdown. In these situations, the cleaning equipment may not have completed the self-cleaning process. Furthermore, after receiving a self-cleaning command, it's possible that hot water self-cleaning or drying operations haven't been performed yet, or only room temperature water washing or lukewarm water washing has been performed. In this case, cooling operations may not be necessary.

[0191] It is understandable that the heating process involves temperatures above 45°C. For example, the hot water temperature in a self-cleaning system is 60°C, 80°C, or even 100°C, the heating device has been turned on, and the temperature of the heating device is greater than 45°C, etc.

[0192] The system determines whether to perform a cooling action based on whether the self-cleaning process includes heating. If the self-cleaning process does not include heating, the cleaning system will not perform a cooling action. This reduces unnecessary cooling, lowers energy consumption, and improves the user experience.

[0193] It should also be noted that if there is still liquid in the cleaning tank when the self-cleaning stops (this liquid may be the cleaning liquid just sprayed out by the water distributor, or it may be dirt), then when the host is cooling down, the suction action can be performed multiple times. The suction action will first remove the liquid in the cleaning tank, and then generate a cooling airflow to cool the cleaning tank.

[0194] In step S110, it can be determined from historical records whether the self-cleaning actions performed include heating actions. However, it is not limited to this.

[0195] In some optional embodiments, the stop instruction includes a self-cleaning interruption stop instruction. For example, if the drying stop instruction is the last action instruction of self-cleaning, then the self-cleaning interruption stop instruction in step S110 may be a stop self-cleaning instruction received before the drying stop instruction.

[0196] If the stop command is a self-cleaning interruption stop command, it is necessary to first determine whether the executed self-cleaning actions include heating actions, and then determine whether to execute the cooling action based on the determination result. If the stop command is a stop command after the last self-cleaning action command, it indicates that self-cleaning has been completed. In this case, it is not necessary to determine whether the executed self-cleaning actions include heating actions, and the cooling action can be executed directly. This is conducive to timely response to the cooling action and reduces unnecessary waste of resources.

[0197] In some alternative embodiments, the heating action includes at least one of the following: hot water self-cleaning action, drying action, or ironing action.

[0198] The hot water temperature for self-cleaning can be above 45℃. Ironing refers to the action of ironing the cleaning part by contacting the heat exchanger or heating device with the cleaning part. Generally, as long as the heating device has been turned on for a period of time, it is considered that an ironing action has been performed.

[0199] The cleaning system only initiates heat dissipation when the self-cleaning process includes heating. This reduces unnecessary heat dissipation, lowers energy consumption, and improves the user experience.

[0200] The other contents of Example 2 are the same as those of Example 1, and will not be described again.

[0201] Example 3

[0202] Example 3 provides a control method for a cleaning system. The cleaning system includes a cleaning device and a base. The cleaning device includes a body and a floor brush. The floor brush is equipped with cleaning components. The body is equipped with a suction device. The base is equipped with a cleaning tank for placing the cleaning components. The base is equipped with a heating device and a fan.

[0203] As shown in Figure 5, the control method of Embodiment 3 includes the following steps:

[0204] S210, In response to the self-cleaning stop command, determine the temperature of the heating device;

[0205] S220. If the temperature of the heating device is higher than the preset temperature, control the cleaning system to perform heat dissipation.

[0206] Regardless of whether the entire self-cleaning process is complete, once self-cleaning stops, the system can determine whether to perform a cooling action based on the temperature of the heating element. If the temperature of the heating element is less than or equal to the preset temperature, the cleaning system can be controlled not to perform a cooling action. This reduces unnecessary cooling actions. For example, during the self-cleaning process, if the cleaning parts are found to be only lightly soiled, a higher hot water temperature is unnecessary, and the drying temperature is also low. In such cases, although the heating element is activated during the self-cleaning process and overheating occurs, the low temperature minimizes the possibility of overheating or burns. In these situations, no cooling action is required, reducing energy consumption and improving the user experience.

[0207] Similar to the aforementioned embodiments, the heating device includes an infrared heating device, which includes an infrared emitter, a transmitting element, and a reflecting element. The transmitting element is located below the cleaning element, and the infrared emitter is located below the transmitting element. The reflecting element and the transmitting element together enclose a cavity, and the infrared emitter and temperature sensor are both located inside the cavity. The temperature sensor uses the detected air temperature near the infrared emitter as the temperature of the heating device.

[0208] The other contents of Example 3 are the same as those of Example 2, and will not be described again.

[0209] Example 4

[0210] Based on the foregoing description, Embodiment 4 provides a cleaning system, which includes a cleaning device, a base, and a controller; the controller is configured to execute the control method of the cleaning system described in any of the foregoing embodiments.

[0211] Example 4 has the same technical effects as Examples 1 to 3 described above, and will not be described again.

[0212] In addition, this application also provides a computer-readable storage medium storing computer-executable instructions, which, when executed by a processor, implement the above-mentioned control method.

[0213] The computer-readable storage medium provided in this embodiment can execute the control method of the above embodiment. Its implementation principle and technical effect are similar, and will not be described again here.

[0214] The aforementioned computer-readable storage medium can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic storage, flash memory, magnetic disk, or optical disk. The readable storage medium can be any available medium accessible to a general-purpose or special-purpose computer.

[0215] An exemplary readable storage medium is coupled to a processor, enabling the processor to read information from and write information to the readable storage medium.
