[0018] The present invention provides a control method, system, device, and storage medium for a washing appliance. This method pre-analyzes the user's washing habits in depth and comprehensively, providing accurate data reference for automatic washing tasks. This process integrates multiple dimensions, such as door movement time, human activity status, and real-time opening and closing status, to determine whether the washing appliance meets the conditions for automatic washing. This approach significantly improves the accuracy of automatic washing and effectively reduces the risks that may arise during the automatic washing process, thereby achieving a comprehensive improvement in the user experience.

[0019] The terms "first," "second," "third," "fourth," and so on (if any) in the description and claims of the present invention and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that shown or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product, or apparatus.

[0020] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 , an embodiment of the control method of the washing appliance in the embodiment of the present invention includes:

[0021] The control system of the washing appliance includes a control system applied to the washing appliance, and the control system of the washing appliance includes: a control device and a door body and a washing tank electrically connected to the control device;

[0022] In one embodiment, the washing liner is provided with an inlet and outlet for tableware, the door body is provided in the inlet and outlet for tableware, and the door body is movably connected to the washing liner; a cleaning component, a drying air intake component and a condensing exhaust component are provided in the washing liner; the cleaning component, the drying air intake component and the condensing exhaust component are utilized to achieve the task of cleaning the tableware.

[0023] It should be noted that the cleaning component, the drying air intake component and the condensing exhaust component are all cleaning components, drying components and condensing components of existing dishwashers. The specific structures and working principles are all existing technologies and will not be repeated here.

[0024] The control method of the washing appliance comprises the steps of:

[0025] 101. Obtain historical washing events and confirm the user's washing time interval based on the historical washing events;

[0026] In this embodiment, all past washing records are extracted from the appliance's storage system. These records may include various information, such as wash start and end times, and wash modes. This historical data can be analyzed, for example, to count the frequency of wash events within different time periods. If it is found that most of a user's washing activity occurs between 7:00 PM and 9:00 PM, this period can be preliminarily determined to be the user's primary washing time. Washing patterns on different days of the week can also be considered, for example, weekends may be more frequent than weekdays. Understanding a user's washing habits helps optimize the appliance's resource allocation. For example, prior to a user's frequently used washing time, water can be preheated or certain wash programs can be preloaded to shorten overall washing time and improve the user experience. Furthermore, the appliance's energy usage strategy can be optimized based on the user's preferred washing schedule. Self-maintenance (such as filter cleaning) can be performed during off-peak hours to avoid resource usage when the user is likely to be using the appliance. Furthermore, user washing time periods can be configured through the app or product features.

[0027] 102. Get the real-time opening and closing status of the door;

[0028] In this embodiment, real-time monitoring of the door opening and closing state is an important measure to ensure washing safety. Before determining whether to perform automatic washing, it is necessary to ensure that the door is in a closed state to prevent water from overflowing or causing harm to the user.

[0029] 103. Confirm the action time according to the real-time opening and closing status, and compare the action time with the user's washing time interval;

[0030] In this embodiment, by comparing the action time and the user's washing time interval, the user's operation intention can be further determined. If the action time is within the user's washing time interval, it is more likely that the user is performing a normal washing operation, thus providing a basis for subsequent more accurate control.

[0031] 104. If the action time is within the user's washing time interval, obtain the human activity status within the preset radar sensing area and perform signal determination on the human activity status;

[0032] 105. If the human activity state is a state with no human activity signal, the validity of the real-time door opening and closing state is judged according to the preset door opening and closing conditions;

[0033] In this embodiment, radar sensors installed around the washing appliance define a sensing area, for example, a semicircular area with a radius of 2 meters in front of the appliance. Changes in reflected waves are used to determine whether there is movement within the area, i.e., human activity. If the reflected waves show continuous, regular changes, it is considered a human activity signal; if the reflected waves show little change, it is considered a human activity signal. Detecting human activity can enhance the safety and intelligence of the appliance. If the action time falls within the washing time interval and there is sustained human activity within the sensing area, it may be that the user is placing or removing dishes. In this case, some automatic operations can be suspended to avoid disrupting the user. If there is no human activity signal, it can be inferred that the user has completed the operation and left, providing conditions for subsequent automatic control. Preset door opening and closing conditions may include a maximum door opening time and a door angle within a reasonable range. For example, a door open for more than 3 minutes may be considered an abnormal condition, or the door opening angle exceeds 90 degrees. Based on these conditions, the real-time detected door opening and closing status is evaluated to determine whether the current opening and closing status is valid.

[0034] 106. If the real-time opening and closing status meets the door opening and closing conditions, an automatic washing instruction is generated.

[0035] In this embodiment, when the real-time opening and closing status meets specific preset conditions, this indicates that the washing appliance has reached a safe state and can autonomously perform automatic washing tasks. In this case, the user does not need to manually set any washing programs, thus achieving great convenience and speed. The addition of this function significantly enhances the intelligence and automation level of the washing appliance, thereby greatly improving the user experience.

[0036] In an embodiment of the present invention, the user's washing time interval is determined by analyzing historical washing events, so that the washing appliance can better adapt to the user's daily usage habits; the automatic generation of washing instructions avoids the user from manually selecting the appropriate washing mode, making the washing process more intelligent and personalized; the human activity status is detected by the radar sensing area, and the automatic washing instruction is generated only when the human activity status is no signal and the door opening and closing status meets certain conditions, further ensuring that the washing operation is performed without human interference, reducing the risk of injury due to accidental contact between the user and the running machine; understanding the user's washing time interval helps to optimize the energy use strategy of the appliance.

[0037] A second embodiment of the control method of the washing appliance according to the present invention includes:

[0038] The control system of the washing appliance further includes: a microwave radar electrically connected to the control device;

[0039] 201. Obtain environmental geographic information and the radar position coordinates of the microwave radar, and confirm the activity radiation range based on the environmental geographic information;

[0040] 202. The radar position coordinates are used as the origin and the active radiation range is used as the diffusion range of the origin to form the radar sensing area;

[0041] 203. Within a preset activity time interval, the activity status of a human body within the radar sensing area is acquired by microwave radar, and a signal determination is performed on the activity status of the human body.

[0042] In this embodiment, the radar's location coordinates are used as the origin, combined with the activity radiation range to form a radar sensing area, allowing the system to accurately detect human activity within this area. During a preset activity time interval, the microwave radar will acquire real-time human activity within the radar sensing area and perform signal evaluation. If the system detects a user performing activity near the dishwasher (such as placing dishes or adding detergent), and no one approaches the washing machine within the preset cleaning time, the system automatically initiates the cleaning cycle, achieving the desired automatic cleaning effect.

[0043] A third embodiment of the control method of the washing appliance according to the present invention includes:

[0044] 301. Obtain historical washing events, and extract a washing record set from the historical washing events according to a preset filter field;

[0045] 302. Obtain the timestamp information of each record in the washing record set, and filter the washing record set according to a preset valid time condition to obtain a washing valid information set whose timestamp information meets the valid time condition;

[0046] 303. Aggregate the timestamp information of the effective washing information set based on a preset time granularity rule to obtain the number of washes and the average washing time in each time dimension;

[0047] 304. Construct a washing time trend chart based on the number of washes and the average washing time in each time dimension, and confirm the user's washing time interval based on the washing time trend chart.

[0048] In this embodiment, the system deeply mines historical washing events, extracting information related to the user's washing habits and extracting the timestamp information from each record. These timestamps record the specific moment of each wash and can be used to analyze the user's washing habits. Using pre-set valid time conditions (such as timestamps containing both start and stop times, or timestamps where the start or stop times do not conform to standard time formats), the system can filter out invalid and missing data. The system then aggregates and organizes the timestamp information within the valid washing data set according to pre-set time granularity rules. This method allows for the generation of wash counts and average wash times within different time periods. This data reveals the user's washing preferences at different times of the day, week, or month. The system then uses this data to construct an intuitive wash time trend chart. This chart not only displays the user's wash counts across different time periods but also reveals the changing trends in average wash time. By observing the chart, one can clearly understand the user's washing habits at different times of the day, week, month, or year, thereby identifying the user's most frequently used wash time periods.

[0049] A fourth embodiment of the control method for a washing appliance according to the present invention includes:

[0050] The door opening and closing conditions include a threshold for the total number of doors opened and closed and a threshold for the interval between opening and closing the doors;

[0051] 401. Obtain the number of door openings and door closings based on the real-time door opening and closing status, and obtain the total number of door openings and closings in real time based on the number of door openings and door closings;

[0052] 402. Obtain the action time of each door opening and closing action based on the real-time opening and closing status, and calculate the total interval time of the door opening and closing actions based on all the action times;

[0053] 403. Compare the total number of door openings and closings in real time with the total number of door openings and closings threshold. If the total number of door openings and closings in real time is greater than or equal to the total number of door openings and closings threshold, determine the validity of the total interval time based on the door opening and closing interval time threshold.

[0054] In this embodiment, by monitoring the number of door openings and closings in real time, it is possible to determine whether the user has completed placing the dishes. Furthermore, by analyzing the intervals between door openings and closings, it is possible to further determine whether the user's placing actions are continuous. This dual verification mechanism helps ensure that the user has completely placed the dishes in the washing machine. This allows the washing machine to perform automatic cleaning tasks in a completely safe environment, thereby improving cleaning efficiency and safety.

[0055] A fifth embodiment of the control method for a washing appliance according to the present invention includes:

[0056] 501. Obtain the current state of the door body according to the real-time opening and closing state, and perform state analysis on the current state;

[0057] 502. If the current state is the door-open state, an automatic wash termination instruction is generated; the automatic wash termination instruction is used to terminate the washing task of the washing tank.

[0058] To ensure the safe operation of the washing machine, this embodiment monitors the door's current state to determine whether it was most recently closed. If the detection result indicates the door is currently open, this indicates a risk of the washing machine automatically initiating a cleaning cycle without the door closed. To prevent this risk, the system immediately generates a command to terminate automatic cleaning. This command ensures that the washing machine does not perform any automatic cleaning tasks while the door remains open, thereby avoiding potential safety issues or damage caused by automatic cleaning.

[0059] A sixth embodiment of the control method for a washing appliance according to the present invention includes:

[0060] 601. Obtain the real-time load capacity of the washing tank;

[0061] In this embodiment, by knowing the different load capacities, different washing water volumes, detergent dosages, and washing times can be determined, thereby achieving personalized and precise washing, improving washing effects, and saving resources. It can also avoid the problem of subsequent washing appliances performing empty-load washing during automatic cleaning, ensuring that there are tableware in the washing tank.

[0062] 602. Determine the status of the real-time load capacity according to a preset load capacity condition. If the real-time load capacity satisfies the load capacity condition, obtain an automatic wash permission instruction for the washing tank.

[0063] In this embodiment, the preset load condition is a range (for example, the minimum load is 1 kg and the maximum load is 5 kg). When the load detected by the real-time load sensor is within this range, it is determined that the load condition is met.

[0064] 603. Generate a user interaction instruction based on the real-time load amount and the automatic washing permission instruction;

[0065] 604. Obtain user feedback information according to the user interaction instruction within a preset feedback time. If no user feedback information is obtained within the preset feedback time, generate an automatic washing instruction according to the automatic washing permission instruction.

[0066] In this embodiment, obtaining the automatic wash permission instruction for the washing tank is the starting point of the entire automatic cleaning process. This ensures that the washing appliance has obtained the user's explicit authorization before starting to work or that the system has determined the necessity of cleaning based on preset conditions. User interaction instructions are generated based on the real-time load volume and the automatic wash permission instruction. By accurately calculating the weight of the dishes in the tank and the degree of stains, the washing appliance can provide the user with one or more cleaning solutions, greatly improving the user experience. User feedback information is obtained according to the user interaction instruction within the preset feedback time. If the user provides feedback within the specified time, the system will make corresponding adjustments based on the user's instructions; if the user does not respond, the system will automatically execute the pre-set cleaning program. This design not only ensures that the user can intervene in time when needed, but also avoids cleaning delays caused by user negligence, ensuring the smoothness and efficiency of the entire cleaning process.

[0067] Based on the load, the system searches a database of wash programs pre-stored in the appliance's control system. For example, for a 3 kg load, a standard wash cycle might be selected, including the appropriate wash time, wash intensity, and detergent dosage. Automatic wash instructions incorporating these parameters are generated and sent to the appliance's various actuator components, such as the motor, water inlet valve, and detergent dispenser. This automates the washing process, eliminating the need for users to manually set wash programs and providing a convenient and efficient experience. Furthermore, instructions generated based on the real-time load ensure optimal washing results while maximizing resource conservation (such as detergent, water, and electricity), enhancing the intelligence and automation of the appliance and improving user satisfaction.

[0068] A seventh embodiment of the control method for a washing appliance according to the present invention includes:

[0069] 701. Perform data analysis on human activity status to obtain user activity range, operation warning range, and user activity trajectory;

[0070] 702. Compare the user activity trajectory with the user activity range and the operation warning range to analyze the number of times the user enters the user activity range and the number of times the user enters the operation warning range, and obtain the number of warnings and the number of alerts;

[0071] 703. Compare the number of warnings with a preset first entry threshold. If the number of warnings is less than the first entry threshold, compare the number of warnings with a preset second entry threshold.

[0072] 704. If the number of warnings is less than the second entry number threshold, it is determined that the human activity state is a state without human activity signals.

[0073] In this embodiment, data analysis of human activity status accurately captures the user's activity range, operation warning range, and activity trajectory. For example, when a user moves around the home, the system can identify their movement paths between the living room, bedroom, and kitchen, thereby constructing a detailed activity map. This analysis helps understand user behavioral trends and predict whether the user is operating a washing machine. By comparing the user's activity trajectory with the user's activity range and operation warning range, the number of times the user enters these two ranges can be analyzed, thereby determining the number of warnings and alerts. Detecting the number of warnings and alerts helps promptly detect potential user activity approaching the washing machine. By comparing the number of warnings and alerts with preset thresholds, the human activity status can be further determined. If the number of warnings is less than the first entry threshold and the number of warnings is also less than the second entry threshold, the current human activity status can be determined as no human activity signal. This determination can be used to trigger a safety mechanism, allowing the washing machine to automatically perform its cleaning task in complete safety.
