Description

Technical Field

[0001] The present disclosure relates to the technical field of household appliances, and particularly to a charging control method, device, and floor cleaning system for a floor cleaning device. Background Art

[0002] To ensure the safety of the battery in the floor cleaning device, when the base station of the floor cleaning system performs a charging and maintenance operation on the floor cleaning device, a charging protection control strategy needs to be activated. The charging protection control strategy includes stopping the charging operation or reducing the power of the charging operation when the real-time ambient temperature is higher than the protection trigger temperature.

[0003] In practical applications, when the base station of the floor cleaning device performs a maintenance operation on the floor cleaning device, the space where the base station accommodates the floor cleaning device may be in a high-temperature state due to the maintenance operation, and the aforementioned high-temperature state is a controllable high-temperature state. In the aforementioned controllable high-temperature state, when it is detected that the real-time ambient temperature is higher than the protection trigger temperature, the charging protection will still be activated according to the charging protection control strategy, so that the floor cleaning device cannot be charged in time, and then the subsequent cleaning operations that can be supported cannot be carried out.

[0035] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not used to limit the protection scope of the present disclosure.

The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments".

It should be noted that the concepts such as "first", "second", etc. mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order of the processes executed by these devices, modules or units or their interdependent relationships.

[0037] It should be noted that the modifications of "one" and "plural" mentioned in the present disclosure are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly specified in the context, it should be understood as "one or more".

[0038] To solve the problem that existing floor cleaning devices cannot be charged due to the charging protection strategy being triggered during the charging operation, resulting in the battery power being unable to support subsequent cleaning operations, the embodiments of the present disclosure provide a new charging control method for floor cleaning devices.

[0039] Before analyzing the charging control method provided by the embodiments of the present disclosure, first make a brief analysis of the structure of the floor cleaning system and the process of the floor cleaning system performing maintenance operations on the floor cleaning device.

[0040] In some specific applications, the floor cleaning system includes a floor cleaning device (commonly known as a sweeping robot) and a base station. After the floor cleaning device completes the floor cleaning operation, it will return to the base station and enter the floor tray of the base station. After returning to the base station and entering the floor tray of the base station, the base station can perform maintenance operations on the floor cleaning device.

[0041] The maintenance operations include the following: roller brush cleaning operation, dust collection (i.e., dust collection) operation, rag cleaning operation, drying operation, and charging operation. Among them, the roller brush cleaning operation, dust collection operation, rag cleaning operation, and drying operation are performed in sequence.

[0042] The roller brush cleaning operation is an operation to clean the lint in the roller brush and the rag of the floor cleaning device through the lint cutting motor. The running time of the roller brush cleaning operation is short, and the roller brush can be cleaned within one or two minutes.

[0043] The dust collection operation is an operation to turn on the fan in the base station and collect the dust swept by the floor cleaning device into the dust collection box by generating negative pressure. The running time of the dust collection operation is short, but the starting power of the dust collection fan is high during the dust collection operation, and a large amount of heat will be generated in a short time.

[0044] The rag cleaning operation is an operation to spray cleaning water on the rag or the roller brush, and at the same time rotate or scrape the rag to clean the roller brush and the rag. The running time of the rag cleaning operation is also short.

[0045] The drying operation is an operation to generate heating heat through the motor heater after the rag cleaning operation is completed, so that the rag and the roller brush of the floor cleaning device are in a high-temperature state, so as to quickly dry the rag and the roller brush through high temperature and avoid mildew. The running time of the drying operation is long, and when the electric heater of the drying operation works, it will generate a lot of heat. In practical applications, the drying operation is mostly executed according to the following strategy: control the set time for the electric heating to generate heat, so that the ambient temperature around the tray (that is, the floor cleaning device) increases, and then control the electric heater to stop working. At this time, the ambient heat around the tray dissipates and cools down; after waiting for the set time, perform the foregoing operation again until the drying operation duration reaches the target set duration.

[0046] The foregoing roller brush cleaning operation, dust collection operation, rag cleaning operation, and drying operation are executed after the floor cleaning device completes a cleaning operation or completes a cleaning operation with a set workload. The foregoing charging operation is executed after the floor cleaning device completes a cleaning operation or when the battery power is lower than the set power.

[0047] During the execution of the charging operation, the floor cleaning system will also turn on the charging protection control strategy. The charging protection control strategy is an operation to stop (possibly pause) the charging operation or reduce the charging power when it detects factors that affect charging safety. The foregoing factors affecting safety include factors such as too high ambient temperature resulting in a decrease in battery heat dissipation efficiency.

[0048] Because the foregoing dust collection operation and drying operation are factors that generate heat and increase the ambient temperature of the environment where the floor cleaning device is located, the charging protection control strategy may be triggered during the execution of the foregoing dust collection operation and / or drying operation.

[0049] In the related art, the problem that the heat generated by the dust collection operation and the drying operation may cause the ambient temperature to be too high and may trigger the charging protection control strategy is not considered. If the ambient temperature is detected to be too high during the dust collection operation or the drying operation, the charging operation will be stopped or the charging power will be reduced.

[0050] However, through heat conduction simulation and actual testing, it is found that although the temperature generated during operations such as the dust collection operation and the drying operation will make the ambient temperature relatively high, it will not have too much impact on the charging safety of the battery. Based on the foregoing considerations, the embodiments of the present disclosure propose a charging control method for a floor cleaning device, and certain strategies in the charging protection control strategy will not be activated when the floor cleaning device performs certain maintenance operations.

[0051] Figure 1 It is a flowchart of the charging control method for the floor cleaning device provided by the embodiments of the present disclosure. As Figure 1 shown, the charging control method for the floor cleaning device provided by the embodiments of the present disclosure includes S110 - S140.

[0052] The charging control method provided by the embodiments of the present disclosure is executed by a controller. The aforementioned controller may be a controller provided on the base station side or a controller provided on the floor cleaning device side.

[0053] S110: When about to start the charging operation for the floor cleaning device or while performing the charging operation for the floor cleaning device, detect the type of other maintenance operations for the floor cleaning device.

[0054] In the embodiments of the present disclosure, the aforementioned other maintenance operations are other operations except the charging operation. As previously exemplified, the other maintenance operations may include the roller brush cleaning operation, the dust collection operation, the rag cleaning operation, and the drying operation.

[0055] In actual operation, the following situations may occur: (1) During the execution of other types of maintenance operations for the floor cleaning device, it is detected that the battery power of the floor cleaning device is less than the charging trigger power, and the floor cleaning device needs to be charged. (2) During the charging operation for the floor cleaning device, other maintenance operations are started. Whether it is the aforementioned situation (1) or situation (2), it is a situation where the charging operation and other maintenance operations are performed simultaneously.

[0056] In specific implementation, the detection of the type of other maintenance operations for the floor cleaning operation may be to read the control logic in the base station controller to determine whether there are other maintenance operations for the floor cleaning device; in the case of determining that there are other maintenance operations for the floor cleaning device, determine the type of other maintenance operations.

[0057] S120: Determine whether the other maintenance operation is a preset maintenance operation; if yes, execute S130; if no, execute S140.

[0058] The preset maintenance operation is a pre-determined operation. The preset maintenance operation is an operation that generates heat during its operation, thereby increasing the ambient temperature. As previously analyzed, the aforementioned dust collection operation and drying operation can be used as preset maintenance operations.

[0059] In a specific application, considering that the working time of the dust collection operation is short and not much power will be charged into the battery of the floor cleaning device during this short time, and the vibration generated during the dust collection operation may cause problems such as charging contact vibration and sparking, the dust collection operation is not used as a preset maintenance operation. And because the execution time of the drying operation is very long, charging the floor cleaning device during the execution duration of the drying operation can significantly increase its battery power, so the drying operation is used as a preset maintenance operation.

[0060] S130: Stop executing the charging protection control strategy for the floor cleaning device.

[0061] S140: Start the charging protection control strategy for the floor cleaning device.

[0062] In the embodiments of the present disclosure, the charging protection control strategy is a strategy of stopping the charging operation or reducing the charging power of the charging operation when it is detected that the real-time ambient temperature is higher than the protection trigger temperature. It should be noted that the real-time ambient temperature mentioned here is the ambient temperature at the location of the floor cleaning device, specifically the ambient temperature of the accommodation cavity or accommodation bin in the base station that accommodates the floor cleaning device, and it is not the ambient temperature of a large space determined by meteorological conditions, building structure, and the location of the base station as conventionally understood.

[0063] As previously analyzed, although the heat generated by preset maintenance operations such as the drying operation raises the ambient temperature to the protection trigger temperature, the safety of the battery is still guaranteed at this time. And in practical applications, the drying operation is periodic heating as previously analyzed, and only during some periods of its operation is the real-time ambient temperature higher than the protection trigger temperature.

[0064] Based on this consideration, when it is determined that the other maintenance operation is a preset maintenance operation, the charging protection control strategy is stopped, so that during the execution of the preset maintenance operation, even if it is detected that the ambient temperature is higher than the protection trigger temperature, the operation is still executed.

[0065] It should be noted that when executing the aforementioned S140 to start the charging protection for the floor cleaning device, it is necessary to start the ambient temperature sensor to detect the real-time ambient temperature.

[0066] By adopting the charging control method provided in the embodiments of the present disclosure, it can be ensured that when the floor cleaning device completes a cleaning operation and has a low battery level, it can still be charged for a period of time, ensuring that its battery has a relatively large amount of power to support the next cleaning operation and avoiding the problem that the next cleaning operation cannot be performed due to power shortage. In the case where the next cleaning operation is a cleaning operation actively triggered by the user, this solution can significantly improve the user experience and avoid the problem of reduced user experience caused by inability to charge.

[0067] Figure 2 It is a flowchart of the charging control method for a floor cleaning device provided in another embodiment of the present disclosure. As Figure 2 shown, the charging control method provided in another embodiment includes S210 - S250.

[0068] S210: While about to start or during the charging operation of the floor cleaning device, detect the type of other maintenance operations for the floor cleaning device.

[0069] S220: Determine whether the other maintenance operation is a set maintenance operation; if so, execute S230; if not, execute S260.

[0070] S230: Stop executing the charging protection control strategy for the floor cleaning device.

[0071] S240: Determine that the set maintenance operation ends, and monitor the real - time ambient temperature.

[0072] S250: Determine whether the real - time ambient temperature drops to the protection exit temperature; if so, execute S260; if not, continue to execute S250.

[0073] S260: Start the charging protection control strategy for the floor cleaning device.

[0074] In the embodiments of the present disclosure, the foregoing S210 - S230 and S260 are the same as the corresponding operation steps in the previous embodiments. Different from the previous ones, after determining that the set maintenance operation ends, the controller controls the ambient temperature sensor to continue detecting the real - time ambient temperature and determines whether the real - time ambient temperature drops to the protection exit temperature. If the real - time ambient temperature drops to the protection exit temperature, the charging protection control strategy for the floor cleaning device can be continued to be started.

[0075] In some embodiments, the charging operation of the floor cleaning device is in the starting stage, that is, the duration of the charging operation is less than the set duration. At this time, due to the electrochemical reaction during the battery charging process, the battery generates heat and the battery temperature rises. If the battery is in a normal state, the battery temperature rise rate is within a reasonable rate range, neither too small nor too large. In addition, after the battery temperature rises to a certain temperature, because the balance between heat generation and heat dissipation is achieved, its temperature will no longer change.

[0076] According to the previous analysis, when the battery charging operation is in the initial stage, the battery temperature rise rate will not be too low. If it is too low, there may be a line fault or a fault in the battery itself. For safety reasons, the battery cannot be charged, or the charging rate should be reduced. If the battery temperature rise rate is relatively high, it indicates that the battery is undergoing a normal electrochemical reaction. At this time, it is possible to determine whether to perform the charging operation according to other conditions.

[0077] Figure 3 is a flowchart of the charging control method for the floor cleaning device provided by some embodiments of the present disclosure. As Figure 3 shown, in some embodiments, the charging control method includes S310 - S360.

[0078] S310: Determine that the floor cleaning device is being charged, and judge whether the duration of the charging operation is less than the set duration; if so, execute S320; if not, execute S330.

[0079] S320: Obtain the measured temperature rise value of the battery in the floor cleaning device within a preset duration, and judge whether the measured temperature rise value is greater than the set temperature rise value; if so, execute S330; if not, execute S360.

[0080] S330: Detect the type of other maintenance operations for the floor cleaning device, and judge whether the other maintenance operations are set maintenance operations; if so, execute S340; if not, execute S350.

[0081] S340: Stop executing the charging protection control strategy for the floor cleaning device.

[0082] S350: Start the charging protection control strategy for the floor cleaning device.

[0083] S360: Stop the charging operation of the floor cleaning device.

[0084] According to the solution mentioned above, in the embodiments of the present disclosure, if it is determined that during the initial charging stage of the battery, the measured temperature rise value is less than the set temperature rise value, it is determined at this time that the battery cannot be charged normally, so the charging operation of the floor cleaning device is directly stopped. If it is determined that the measured temperature rise value of the battery is greater than the set temperature rise value, it is determined that the battery can be charged normally. At this time, according to whether the set maintenance operation is executed, it is determined whether to stop or start the charging protection control strategy for the floor cleaning device.

[0085] Figure 4 It is a flowchart of the charging control method for a floor cleaning device provided in some other embodiments of the present disclosure. As Figure 4 shown, in some embodiments, the charging control method includes S410 - S460.

[0086] S410: Determine that the floor cleaning device is being charged, and monitor the temperature of the battery cells in the floor cleaning device.

[0087] S420: Judge whether the temperature of the battery cells is less than the safety temperature threshold; if so, execute S430; if not, execute S460.

[0088] S430: Detect the type of other maintenance operations for the floor cleaning device, and judge whether the other maintenance operations are set maintenance operations; if so, execute S440; if not, execute S450.

[0089] S440: Stop executing the charging protection control strategy for the floor cleaning device.

[0090] S450: Start the charging protection control strategy for the floor cleaning device.

[0091] S460: Stop the charging operation of the floor cleaning device.

[0092] According to the battery working principle, if the battery temperature is higher than the safety temperature threshold, the battery is probably in an unsafe state (for example, internal short - circuit may occur). In this case, in order not to worsen the battery state, it is necessary to stop charging the battery of the floor cleaning device. If the temperature of the battery cells is less than the safety temperature threshold, the battery can still be charged. At this time, S430 - S450 can be executed to determine whether to execute the charging protection control strategy according to the type of other maintenance operations.

[0093] Of course, in practical applications, Figure 4 the method of the embodiment shown and Figure 3 the method of the embodiment shown can be executed simultaneously in a specific application.

[0094] In addition, in practical applications, the detection of the temperature rise rate during the initial charging stage of the battery and the control of the charging operation based on the temperature rise rate, as well as the detection of the cell temperature and the control of the charging operation based on the cell temperature, can be carried out after determining whether other maintenance operations are set maintenance operations, and are not limited to the sequence limitations in the foregoing embodiments.

[0095] The foregoing mentioned the detection of the real-time ambient temperature. In practical applications, the detection of the real-time ambient temperature can specifically be to obtain the detection temperature of the temperature sensor set in the base station water tank or the water outlet pipeline, and use the detection temperature as the real-time ambient temperature. The following analyzes the reasons why it is more reasonable to use the foregoing detection temperature as the real-time ambient temperature.

[0096] As in the structure and shape of the floor cleaning device in the prior art (the shape is mostly a flat cylindrical structure), the battery is arranged inside the floor cleaning device. If its external environment temperature (such as the air temperature in the tray) is relatively high, it takes a certain period of time for the temperature conduction to cause the battery temperature to rise, resulting in a decrease in the charging safety of the battery. Based on the foregoing considerations, the detection of the real-time ambient temperature should be able to reflect the foregoing temperature conduction characteristics to avoid the problem that the detection result has no reference significance caused by directly detecting the air temperature. To avoid the foregoing problem, in the embodiments of the present disclosure, the ambient temperature is detected by the temperature sensor set in the water tank or the water outlet pipeline as the real-time ambient temperature. Because the external temperature needs to be conducted for a certain period of time to be transmitted to the temperature sensor arranged inside the base station (that is, the water tank or the water outlet pipeline), the detection temperature of the foregoing temperature sensor is more meaningful as a reference.

[0097] In the embodiments of the present disclosure, the charging protection control strategy can be deployed on the side of the floor cleaning device or on the side of the base station. Among them, when the charging protection control strategy is deployed on the side of the floor cleaning device, it can be called a primary charging protection strategy; when the charging protection control strategy is deployed on the side of the base station, it can be called a secondary charging protection strategy. In practical applications, after stopping the charging protection control strategy for the floor cleaning device, the controller can control the output of a prompt message. The prompt message is a message for prompting the user that the charging protection control strategy has been stopped. In a specific implementation, the foregoing prompt message can be output through a speaker or a display device arranged in the floor cleaning system, or can also be output through an electronic device such as a smart phone. In addition, if the controller activates the charging protection control strategy, the controller can also control the output of a corresponding prompt message.

[0098] In addition to providing the foregoing charging control method for the floor cleaning device, the embodiments of the present disclosure also provide a charging control device for the floor cleaning device. Figure 5 It is a schematic structural diagram of the charging control device for the floor cleaning device provided by the embodiments of the present disclosure. As Figure 5As shown, the charging control device 500 of the floor cleaning device includes an operation type determination unit 501 and a control unit 502.

[0099] The operation type determination unit 501 is configured to obtain the type of other maintenance operations for the floor cleaning device while performing a charging operation on the floor cleaning device; the control unit 502 is configured to stop executing the charging protection control strategy for the floor cleaning device when the other maintenance operations include set maintenance operations, and the charging protection control strategy includes stopping the charging operation when the real-time ambient temperature is higher than the protection trigger temperature.

[0100] In some embodiments, the set maintenance operation is a hot air drying operation.

[0101] In some embodiments, after determining that the set maintenance operation ends, the control unit 502 controls to monitor the real-time ambient temperature, and starts the charging protection control strategy for the floor cleaning device when the real-time ambient temperature drops to the protection exit temperature.

[0102] In some embodiments, the control unit 502 obtains the detected temperature of the temperature sensor provided in the water tank or the water outlet pipeline, and uses the detected temperature as the real-time ambient temperature.

[0103] In some embodiments, when the duration of the charging operation is less than the set duration, the control unit 502 controls to obtain the heating rate of the battery in the floor cleaning device, and stops executing the charging protection control strategy when the heating rate is greater than the set heating rate.

[0104] In some embodiments, while controlling the charging operation of the floor device, the control unit 502 also monitors the measured temperature rise value of the battery in the floor cleaning device within a preset duration; when the measured temperature rise value is greater than the set temperature rise value, the control unit 502 stops executing the charging protection control strategy.

[0105] In some embodiments, the controller stops executing the charging protection control strategy for the floor cleaning device, including: stopping the charging protection control strategy when the base station charges the floor cleaning device.

[0106] In some embodiments, after stopping executing the charging protection control strategy for the floor cleaning device, the controller also controls to output a prompt message, and the prompt message is a message for prompting to stop the charging protection control strategy.

[0107] In addition to providing the foregoing charging control method and control device for the floor cleaning device, the embodiments of the present disclosure also provide a floor cleaning system as analyzed above. The floor cleaning system includes a base station, a floor cleaning device, and a controller, and the controller controls the execution status of the charging protection control strategy for the floor cleaning device according to the charging control method as described above.

[0108] In a specific implementation, the controller may be a central processing unit (CPU) or other forms of processing units with data processing capabilities and / or instruction execution capabilities, and may control other components in the water heating device to perform desired functions.

[0109] The embodiments of the present disclosure also provide a storage medium storing a program or instructions, which cause a computer to execute the charging control method of any floor cleaning device provided by the embodiments of the present disclosure. When executed by a computer controller, the computer-executable instructions can also be used to execute the charging control method of any of the above floor cleaning devices provided by the embodiments of the present disclosure to achieve corresponding beneficial effects.

Of course, it can also be implemented by hardware, but in many cases the former is a better implementation manner. Based on such an understanding, the technical solution of the embodiments of the present disclosure, in essence or the part that contributes to the prior art, can be embodied in the form of a software product. The computer software product can be stored in a computer-readable storage medium, such as a floppy disk, a read-only memory (ROM), a random access memory (RAM), a flash memory (FLASH), a hard disk, or an optical disc of a computer, including several instructions for causing a computer device (which may be a personal computer, a server, or a network device, etc.) to execute the methods of the various embodiments of the present disclosure.
