DETAILED DESCRIPTION

[0016] The present invention provides a control method, system, device and storage medium for a washing appliance. The present invention pre-analyzes the user's washing habits in depth and comprehensively to provide accurate data reference for automatic washing tasks. This process combines multiple dimensions such as the door's action time, human activity status, and real-time opening and closing status to determine whether the washing appliance meets the conditions for automatic washing. This processing measure significantly improves the execution accuracy of automatic washing, effectively reduces the risks that may occur during the automatic washing process, and thus achieves a comprehensive improvement in the user experience.

[0017] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated 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 device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0018] 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: 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; In one embodiment, the washing tank is provided with a tableware inlet and outlet, the door body is provided inside the tableware inlet and outlet, and the door body is movably connected to the washing tank; a cleaning component, a dry air intake component and a condensation exhaust component are provided inside the washing tank; the cleaning component, the dry air intake component and the condensation exhaust component are utilized to achieve the task of cleaning the tableware.

[0019] 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.

[0020] The control method of the washing appliance comprises the steps of: 101. Obtain historical washing events, and confirm the user's washing time interval based on the historical washing events; In this embodiment, all past washing records are extracted from the storage system of the washing appliance, and these records may include various information such as the start time, end time, and washing mode of washing. These historical data are analyzed, for example, the frequency of washing events in different time periods can be counted. If it is found that most of the user's washing behaviors are concentrated between 7 pm and 9 pm, this time period can be preliminarily determined as the user's main washing time interval. The washing rules on different days of the week can also be considered, such as the number of washing times on weekends may be more than on weekdays. Understanding the user's washing habits helps to reasonably arrange the resources of the washing appliance. For example, before the user's commonly used washing time interval, the washing water can be preheated in advance or some washing programs can be preloaded, thereby shortening the overall washing time and improving the user experience. In addition, the energy use strategy of the washing appliance can be optimized according to the user's habitual washing time. Some self-maintenance (such as cleaning the filter, etc.) is performed during non-user washing peak hours to avoid occupying resources when the user may use the appliance; in addition, the user's washing time interval can also be set through the app or product function.

[0021] 102. Obtain the real-time opening and closing status of the door; 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.

[0022] 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; 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, thereby providing a basis for subsequent more accurate control.

[0023] 104. If the action time is within the user's washing time interval, the human activity state in the preset radar sensing area is obtained, and a signal determination is performed on the human activity state; 105. If the human activity state is a state without human activity signals, the validity of the real-time opening and closing state is judged according to the preset door opening and closing conditions; In this embodiment, a radar sensor installed around the washing appliance is used to define a sensing area, such as a semicircular area with a radius of 2 meters in front of the appliance. Whether there is an object moving in the area, that is, the human activity state, is determined based on the change of the reflected wave. If continuous and regular changes in the reflected wave are received, it is determined that there is a human activity signal; if the reflected wave is basically unchanged, it is determined that there is no human activity signal. Detecting the human activity state can enhance the safety and intelligence of the appliance. If the action time is within the washing time interval and there is continuous human activity in the sensing area, it may be that the user is placing or taking out tableware. At this time, some automatic operations can be suspended to avoid interference with the user. When it is determined that 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; the preset door body opening and closing conditions may include that the door opening time cannot be too long, whether the door body angle is within a reasonable range, etc. For example, it is stipulated that the door opening for more than 3 minutes is considered an abnormal situation, or the door body opening angle exceeds 90 degrees. According to these conditions, the real-time detected door body opening and closing state is evaluated to determine whether the current opening and closing state is valid.

[0024] 106. If the real-time opening and closing status meets the door opening and closing conditions, an automatic washing instruction is generated.

[0025] In this embodiment, when the real-time opening and closing state meets the preset specific conditions, it indicates that the washing appliance has reached a safe state at this moment, and it can autonomously perform the automatic washing task. In this case, the user does not need to manually set any washing program, thereby achieving great convenience and speed. The addition of this function significantly improves the intelligence and automation level of the washing appliance, thereby greatly improving the user experience.

[0026] 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 need for the user to manually select a suitable washing mode, making the washing process more intelligent and personalized; the human activity state is detected through the radar sensing area, and automatic washing instructions are generated only when the human activity state is no signal and the door opening and closing state meets certain conditions, further ensuring that the washing operation is performed without human interference, reducing the risk of injury caused by the user accidentally touching the running machine; understanding the user's washing time interval helps to optimize the energy use strategy of the appliance.

[0027] A second embodiment of the control method of the washing appliance in the embodiment of the present invention includes: The control system of the washing appliance further includes: a microwave radar electrically connected to the control device; 201. Obtain environmental geographic information and radar position coordinates of microwave radar, and confirm the activity radiation range based on the environmental geographic information; 202. The radar position coordinates are taken as the origin and the activity radiation range is taken as the diffusion range of the origin to form the radar sensing area; 203. Within a preset activity time interval, the activity status of human body in the radar sensing area is obtained by microwave radar, and signal determination of the activity status of human body is performed.

[0028] In this embodiment, the radar position coordinates are used as the origin, combined with the activity radiation range, to form a radar sensing area, so that the system can accurately detect the human activity status in this area. Within the preset activity time interval, the microwave radar will obtain the human activity status in the radar sensing area in real time and perform signal judgment. When the system detects that the user is performing activities near the dishwasher (such as placing tableware, adding detergent, etc.), and no one approaches the washing machine within the preset cleaning time, the cleaning program can be automatically started to achieve the automatic cleaning effect of the dishwasher.

[0029] A third embodiment of the control method of the washing appliance in the embodiment of the present invention includes: 301. Obtain historical washing events, and extract washing record sets from the historical washing events according to preset filter fields; 302. Obtaining the timestamp information of each record in the washing record set, and filtering the washing record set according to a preset effective time condition, so as to obtain a washing effective information set whose timestamp information meets the effective time condition; 303. The timestamp information of the effective washing information set is aggregated based on a preset time granularity rule to obtain the number of washing times and the average washing time in each time dimension; 304. Construct a washing time trend chart according to the number of washes and the average washing time in each time dimension, and confirm the user's washing time interval according to the washing time trend chart.

[0030] In this embodiment, the system deeply mines historical washing events, extracts information related to the user's washing habits, and extracts the timestamp information in each record. These timestamps record the specific moment of each washing and can be used to analyze the user's washing habits. Through the preset valid time conditions (such as the timestamp information has both the start time and the stop time, the start time or the stop time in the timestamp information does not conform to the normal time format, etc.), the system can filter out invalid and missing data; the system will collect and organize the timestamp information in the washing valid information set according to the preset time granularity rules. In this way, the number of washing statistics and the average washing time in different time periods can be obtained. These data reveal the user's washing preferences at different time points in a day, a week, or a month; the system will use these data to build an intuitive washing time trend chart. This chart not only shows the number of washing times of the user in different time periods, but also reveals the changing trend of the average washing time. By observing the chart, the user's washing habits in each period of a day, a week, a month, or a year can be clearly known, thereby confirming the washing time interval most commonly used by the user.

[0031] A fourth embodiment of the control method of the washing appliance in the embodiment of the present invention includes: The door opening and closing conditions include a total number of door opening and closing thresholds and a door opening and closing interval time threshold; 401. Obtain the number of door openings and door closings according to the real-time opening and closing status, and obtain the total number of door openings and door closings in real time according to the number of door openings and door closings; 402. Obtain the action time of each door opening action and door closing action according to the real-time opening and closing state, and calculate the total interval time of the door body opening and closing action according to all the action times; 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 according to the door opening and closing interval time threshold.

[0032] In this embodiment, by real-time monitoring of the number of times the door is opened and closed, it can be determined whether the user has completed the action of placing the dishes. In addition, by analyzing the interval between opening and closing the door, it can be further determined whether the user's action of placing the dishes is a continuous action. Such a double verification mechanism helps to ensure that the user has completely placed the dishes in the washing appliance. In this way, the washing appliance can perform the automatic cleaning task in a completely safe environment, thereby improving the cleaning efficiency and safety.

[0033] A fifth embodiment of the control method of the washing appliance in the embodiment of the present invention includes: 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; 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.

[0034] In this embodiment, in order to ensure the safe operation of the washing appliance, the current state of the door is monitored to determine whether the door has been closed in the most recent action. If the detection result shows that the door is currently open, this means that there is a washing risk, that is, the washing appliance may automatically start the cleaning program when the door is not closed. In order to prevent this risk from occurring, the system will immediately generate an automatic cleaning termination instruction. The purpose of this instruction is to ensure that the washing tank will not perform any automatic cleaning tasks when the door remains open, thereby avoiding safety issues or damages that may be caused by automatic cleaning.

[0035] A sixth embodiment of the control method of the washing appliance in the embodiment of the present invention includes: 601. Obtain the real-time load capacity of the washing tank; In this embodiment, by knowing the different load capacities, different amounts of washing water, detergent usage and washing time can be determined, so that personalized and precise washing can be achieved, washing effects can be improved and resources can be saved. At the same time, the problem of empty-load washing during automatic cleaning of subsequent washing appliances can be avoided, ensuring that there are tableware in the washing tank.

[0036] 602. Determine the state of the real-time load according to the preset load condition. If the real-time load satisfies the load condition, obtain an automatic washing permission instruction for the washing tank. In this embodiment, the preset load condition is a range value (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.

[0037] 603. Generate a user interaction instruction according to the real-time load amount and the automatic washing permission instruction; 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.

[0038] In this embodiment, the automatic washing permission instruction of the washing tank is obtained, which is the starting point of the entire automatic washing process. It ensures that the washing appliance has obtained the user's explicit authorization or the system has determined the necessity of cleaning according to the preset conditions before starting to work. The user interaction instruction is generated according to the real-time load and the automatic washing permission instruction. By accurately calculating the weight of the tableware in the tank and the degree of stains, the washing appliance can provide the user with one or more cleaning solutions, which greatly improves the user experience. The user feedback information is obtained according to the user interaction instruction within the preset feedback time. If the user gives feedback within the specified time, the system will make corresponding adjustments according to 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.

[0039] The washing program database pre-stored in the washing appliance control system is searched according to the load. For example, for a load of 3 kg, a standard washing mode may be selected, including the appropriate washing time, washing intensity and detergent dosage. Automatic washing instructions containing these parameters are generated and sent to various actuators of the washing appliance, such as the motor, water inlet valve, detergent dispensing device, etc. The washing process is automated, and users do not need to manually set the washing program, which is convenient and fast. Moreover, the instructions generated according to the real-time load can ensure the washing effect while saving resources (such as detergent, water and electricity) to the greatest extent, improve the intelligence and automation level of the washing appliance, and enhance user satisfaction.

[0040] A seventh embodiment of the control method of the washing appliance in the embodiment of the present invention includes: 701. Perform data analysis on human activity status to obtain user activity range, operation warning range and user activity trajectory; 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 warnings; 703. Compare the number of warnings with a preset first entry number threshold. If the number of warnings is less than the first entry number threshold, compare the number of warnings with a preset second entry number threshold. 704. If the number of warning times is less than the second entry times threshold, it is determined that the human activity state is a state without human activity signals.

[0041] In this embodiment, data analysis of the human activity state can accurately obtain the user's activity range, operation warning range and user's activity trajectory. For example, when the user is active at home, the system can identify the movement path between the living room, bedroom and kitchen, thereby constructing a detailed activity map. This analysis helps to understand the user's behavior trend and predict whether the user has the behavior of operating the washing appliance. By comparing the user's activity trajectory with the user's activity range and the operation warning range, the number of times the user enters these two ranges can be analyzed, and then the number of warnings and the number of warnings can be obtained. By detecting the number of warnings and the number of warnings, it is helpful to timely discover whether the user has the potential behavior of approaching the washing appliance. The number of warnings and the number of warnings are compared with the preset thresholds respectively, and the human activity state can be further judged. If the number of warnings is less than the first entry number threshold, and the number of warnings is also less than the second entry number threshold, it can be judged that the current human activity state is a state without human activity signals. This judgment result can be used to trigger a safety mechanism so that the washing appliance can automatically perform the cleaning task in a completely safe situation.
