Technical Field
[0001] The present application relates to the technical field of intelligent home appliance safety control, and in particular, to a washing machine safety protection control method and system. Background Art
[0002] With the continuous development of washing machine technology, washing machines have become increasingly versatile and have gradually become a must-have appliance in every household. However, due to the large internal space and the fact that washing machines are often placed in areas such as bathrooms or balconies, they run for long periods of time without supervision, especially when using WiFi remote control. If children accidentally enter the washing machine drum while playing, the operation of the washing machine can cause immeasurable harm to the children.
[0003] The existing technology mainly uses a gravity sensor installed in the washing machine drum to determine whether the washing machine can be operated based on whether the weight in the drum exceeds a threshold. When the child is light in weight, there is a risk of misjudgment. The solution of using gravity sensor weighing to determine whether there is a child in the drum to prevent starting has many problems, such as inaccurate sensor sensitivity, the possibility of sensor failure or malfunction, large differences in children's weight, the position of the child in the drum affecting weight distribution, uneven placement of the washing machine causing sensor calibration failure and inaccurate reading, and the child opening the door and climbing into the drum after weighing, which may cause the washing machine to be unable to be used normally or cause the washing machine to be started after the child climbs into the drum.
[0004] In addition, in other technical documents, detection is also performed by setting up infrared thermal sensors, but infrared thermal sensors are easily blocked and interfered by clothing. Summary of the Invention

[0041] The embodiment of the present invention discloses a washing machine safety protection control method and system to solve the problems of low sensor sensitivity and poor safety in the existing solution of using a gravity sensor to determine whether there is a child in the drum to prevent starting.
[0042] In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless they conflict.
[0043] See also Figure 1-2 , Figure 1 A schematic flow chart of a method for controlling safety protection of a washing machine provided in an embodiment of the present application.
[0044] In a specific embodiment, the washing machine safety protection control method provided in this application includes:
[0045] S11: Detecting whether there are any organisms in the preset area of the washing machine;
[0046] S12: Detect the door opening and closing status;
[0047] S13: When the presence of a biological organism is detected in a preset area of the washing machine and the door is in an open state, the safety lock is activated and the remote control function is disabled.
[0048] The system detects biological objects such as children or pets approaching or reaching into the washing machine area. The preset area is the space near the washing machine door, around the operation panel or within other set ranges, such as the space within 0.3 meters in front of the washing machine door. The open and closed status of the door can be detected by corresponding sensors, such as micro switches or magnetic switches. When the safety lock is activated, the door or control system is locked to prevent accidental startup or shutdown. At the same time, the remote control function is disabled, and the remote control function includes remote control instructions based on Wi-Fi, Bluetooth or ZigBee protocols. It includes prohibiting control through mobile terminals such as mobile phone apps, voice assistants, etc.
[0049] In one embodiment, biological body detection can be achieved by setting corresponding sensors, such as infrared proximity sensors, TOF cameras, millimeter wave radars, and pyroelectric sensors, with a detection range of 0.5-1.8m; door status detection can be achieved by setting micro switches, magnetic switches, Hall sensors, and motor position feedback, preferably a Hall sensor + micro switch combination, and the main controller is an STM32F407VGT6 microprocessor; safety lock control can be achieved by setting electromagnetic locks, motor locking mechanisms, buzzer alarm prompts, etc.; disabling the remote control function can be achieved by cutting off Wi-Fi module communication, pausing Bluetooth connection, blocking App command responses, etc.
[0050] The specific working principle is: after the system is started, it continuously monitors the environmental conditions around the washing machine; when the infrared sensor / camera / pressure sensing device detects the approach of a person or animal (that is, the "presence of a living organism"); at the same time, it determines whether the washing machine door is in the open state; if both conditions are met at the same time, the safety protection mechanism is triggered: the safety lock is activated to prevent the door from being closed or the program from being started; the remote control interface is disabled to avoid remote misoperation; and the protection state is automatically released after the organism leaves and the door is closed.
[0051] In a preferred embodiment, the specific control method includes:
[0052] S111: Using an infrared sensor or a TOF camera located near the door of the washing machine, detecting in real time whether there is a living organism in a preset area of the washing machine;
[0053] S112: Detecting the open / closed state of the washing machine door through a micro switch or a magnetic sensor on the door body;
[0054] S113: When a living organism is detected in a preset area of the washing machine and the washing machine door is open, the controller automatically activates the door safety lock to prevent the door from closing accidentally;
[0055] S114: At the same time, the controller cuts off the remote control communication channel and temporarily disables the remote control function of the washing machine through the smart terminal (such as a mobile phone app);
[0056] S115: When the organism leaves the preset area of the washing machine and the door is closed, the safety lock is automatically released and the remote control function is restored.
[0057] This method effectively prevents accidents caused by improper operation when children or pets are close to the washing machine, thereby improving the safety and intelligence level of washing machine use.
[0058] In another embodiment, the control method further includes:
[0059] Detect whether the door switch control signal is received;
[0060] When the presence of a living organism is detected within a preset area of the washing machine and a switch control signal is received, the safety lock is activated and the remote control function is disabled.
[0061] Among them, the switch control signal includes the opening / closing door operation instructions issued by the user through physical buttons, touch screen, voice assistant or App, and disables the remote control function, such as blocking the opening / closing door operation instructions issued by the touch screen, voice assistant or App.
[0062] Specifically, the method further includes:
[0063] When the door is detected to be in a closed state and the preset unlocking action is performed on the local operation panel, the remote control function is restored.
[0064] When the door is detected to be in a closed state, it is ensured that there are no living organisms inside; the preset unlocking action is to enter specific unlocking instructions or steps on the local operation panel to restore the remote control function, that is, to unblock remote control interfaces such as Wi-Fi and Bluetooth.
[0065] The specific working principle is: the washing machine control system continuously monitors the door status: whether it is in the closed state; at the same time, it monitors whether there is a user performing a preset unlocking action on the local operation panel: such as entering a specific password, pressing a specific combination of keys, scanning a fingerprint, etc.; when the following two conditions are met: the door is in the closed state; the user successfully performs the preset unlocking action on the local operation panel; the system releases the security protection mechanism: restores the remote control function, and allows control through mobile phone apps, voice assistants, etc.; optionally, a prompt sound or indicator light signal is issued to inform the user that the remote control function has been restored.
[0066] In one embodiment, the preset unlocking action is:
[0067] Press the Start button three times within the preset time on the local operation panel.
[0068] The local operation panel is the physical or touch interface on the washing machine. The start button, typically the "On / Off / Pause" button, is used to start a washing machine program. A preset timer of 1 or 1.5 seconds is used to determine whether the clicks are rapid and continuous. A triple press is defined as the user pressing the start button three times in a short period of time. For key detection, a microcontroller collects the start button press signal and uses a timer to record the time interval between the two presses. The microcontroller then determines whether the "three clicks + time window" condition is met. If so, it removes the WiFi or Bluetooth control shield and allows remote command responses.
[0069] The specific working principle is: the washing machine disables the remote control function in the safety protection state; the system continuously monitors the pressing events and time intervals of the start button; when it detects that the user presses the start button three times in a row within the preset time: the system determines it as a valid unlocking action; activates the remote control function; if the key press interval exceeds the preset time, or the number of key presses is insufficient, the unlocking will not be triggered; optionally, visual or auditory feedback (such as flashing indicator light, beeping prompt) is issued to confirm that the unlocking is successful.
[0070] For example, if a user presses the "Start / Pause" button three times within 1.5 seconds, the system recognizes it as a valid unlocking action. The controller uses a built-in timer to timestamp the key press and determine whether the continuous click condition is met. If so, the security protection state is released, the remote control function is restored, and the successful unlocking is reported through an indicator light or a prompt tone. This unlocking method does not require additional hardware input devices and can be achieved by using the washing machine's existing start button. It is simple to operate and has a low false trigger rate, making it suitable for ordinary home users to quickly restore remote control functions.
[0071] In another embodiment, the preset receiving action is to long press the local panel WiFi icon for greater than or equal to 2 seconds; the local panel WiFi icon is the WiFi function representation area on the washing machine operation panel, which can be a physical button or a touch icon; if the user continues to press the icon for more than a set time, it is considered a long press; specifically, a time judgment threshold is set to identify whether the user intends to perform the unlocking action.
[0072] The specific working principle is: when the washing machine is in the safety protection state, the remote control function is disabled; the system continuously monitors the pressing status and duration of the WiFi icon on the local operation panel; when it detects that the user has long pressed the icon and the duration is ≥2 seconds: the system determines it as a valid unlocking action; the restriction on the remote control function is lifted; if the pressing time is less than 2 seconds, it is regarded as a normal operation and does not trigger unlocking; the unlocking success status can be optionally fed back through flashing indicator lights, buzzer prompts, etc.
[0073] In addition, the system can provide users with feedback on the unlocking success status through flashing LED lights, buzzer prompts, or text prompts on the display screen, ensuring transparent and controllable operations.
[0074] This unlocking method is intuitive and easy to operate. It can be achieved using the existing WiFi icon area without the need for additional hardware support, and has good user experience and security.
[0075] In one embodiment, the method further includes:
[0076] When the safety lock is activated, the door opening and closing instructions from the cloud are discarded and an alarm message is sent to the preset terminal.
[0077] When the safety lock is activated, it means that the washing machine is currently in a protected state, unauthorized operations are prohibited, and it will not respond to door opening and closing commands issued remotely from mobile phone apps, cloud servers, etc. The preset terminal is the user's bound smartphone, home gateway or smart home control terminal. The alarm information can be in the form of text messages, APP push, buzzer prompts, LED flashing, etc.
[0078] The specific working principle is: when the washing machine detects the presence of a biological organism and the door is open, the safety lock is activated; after entering the safety protection mode: all door switch instructions from the cloud are refused to execute; the relevant requests are discarded or a "reject execution" status code is returned; at the same time, an alarm message is sent to the user's bound terminal through the communication module (such as Wi-Fi / Bluetooth): prompting that the current washing machine is in a safety protection state; reminding the user to check the surrounding environment of the washing machine; after the user confirms and completes the unlocking action, the normal remote control function is restored.
[0079] In a preferred embodiment of the present invention, the washing machine safety protection control method further includes the following steps:
[0080] When a living organism is detected in a preset area of the washing machine and the door is open, the controller activates the safety lock mechanism;
[0081] At this time, the system filters the door opening and closing instructions received from the cloud or smart terminal, directly discards them or returns an error response code to prevent remote misoperation;
[0082] At the same time, the controller sends an alarm message to the preset user terminal through the communication module, reminding the user that the current washing machine is in a safety protection state and reminding the user to check whether there are children or pets around the washing machine;
[0083] Alarm information can be sent through smartphone App push, text messages, voice broadcasts, etc. to ensure that users are informed of abnormal situations in a timely manner.
[0084] This method not only ensures the safety of washing machine use, but also enhances human-computer interaction capabilities and improves the user's perception and response efficiency of the device status.
[0085] In another embodiment, the alarm information includes a real-time environment photo.
[0086] When an abnormal state is detected, an alarm message is sent to the user, and image data of the area around the washing machine is collected through the camera. When the washing machine enters a safety protection state (for example, the presence of a living organism is detected and the door is open), the controller activates the safety lock and disables the remote control function. At the same time, the local camera is triggered to collect real-time images of the environment around the washing machine. The image is packaged as part of the alarm message and sent to the preset terminal (such as a bound smartphone). The user can view the current environment photo through the App to determine whether it is a false alarm or a real dangerous situation. Optionally, the user is supported to remotely confirm or perform emergency operations through the App.
[0087] Among them, image data of the area surrounding the washing machine can be collected through a wide-angle camera module integrated into the washing machine shell, top or installed on the bracket.
[0088] In a preferred embodiment of the present invention, when the washing machine is in a safety protection state, the controller activates a camera module integrated into the washing machine body or an external bracket;
[0089] The camera collects real-time images of the washing machine's surroundings, which are then processed by the control system (e.g., compressed and timestamped).
[0090] The controller encapsulates the image and text alarm information together and sends them to the preset user terminal through the Wi-Fi communication module;
[0091] Users can view alarm notifications containing real-time photos by binding to the App, and intuitively determine whether there are organisms or other abnormal conditions around the washing machine.
[0092] This method improves the accuracy and visualization of security alarms by introducing image perception capabilities, helping users to quickly respond to potential risks and is suitable for the high security requirements of smart home scenarios.
[0093] In one embodiment, it further includes:
[0094] sending a first sound wave signal;
[0095] Receive reflected sound waves and extract time series features through a recurrent neural network to distinguish between children crawling and pets moving.
[0096] Specifically, after the system is started, it sends detection sound waves to the area around the washing machine through the ultrasonic sensor; when an object approaches, the sound waves are reflected back and collected by the receiving module; the control system converts the received sound wave signal into time series data; the received time series signal is analyzed using the existing trained RNN model to identify the target's movement pattern; based on the model output, it is determined whether it is "child crawling" or "pet moving": if it is a child, it enters a high-level safety protection state; if it is a pet, it may only record the event without triggering strong intervention; combined with the door status and user operation intention, the safety lock and remote control strategy are dynamically adjusted.
[0097] like Figure 2 As shown, Figure 2 This is a structural block diagram of a washing machine safety protection control system provided in an embodiment of the present application. Based on the above method embodiment, the present application also provides a washing machine safety protection control system, which is configured corresponding to the above method, including:
[0098] The organism detection module 110 is used to detect whether there are organisms in a preset area of the washing machine;
[0099] Door status detection module 130, used to detect the door open or closed status;
[0100] The main controller 120 is connected to the organism detection module and the door status detection module respectively. When it detects the presence of an organism in a preset area of the washing machine and the door is in an open state, it activates the safety lock and disables the remote control function.
[0101] The system detects biological objects such as children or pets approaching or reaching into the washing machine area. The preset area is the space near the washing machine door, around the operation panel or within other set ranges, such as the space within 0.3 meters in front of the washing machine door. The open and closed status of the door can be detected by corresponding sensors, such as micro switches or magnetic switches. When the safety lock is activated, the door or control system is locked to prevent accidental startup or shutdown. At the same time, the remote control function is disabled, and the remote control function includes remote control instructions based on Wi-Fi, Bluetooth or ZigBee protocols. It includes prohibiting control through mobile terminals such as mobile phone apps, voice assistants, etc.
[0102] In one embodiment, the biological detection module can be implemented by setting corresponding sensors, such as infrared proximity sensors, TOF cameras, millimeter wave radars, and pyroelectric sensors; the door status detection module can be implemented by setting micro switches, magnetic switches, Hall sensors, and motor position feedback, and the safety lock control can be implemented by setting electromagnetic locks, motor locking mechanisms, buzzer alarm prompts, etc.; disabling the remote control function can be achieved by cutting off Wi-Fi module communication, pausing Bluetooth connection, blocking App command responses, etc.
[0103] The main controller is connected to the biological body detection module and the door state detection module respectively, and can be set as a microcontroller.
[0104] The specific working principle is: after the system is started, it continuously monitors the environmental conditions around the washing machine; when the infrared sensor / camera / pressure sensing device detects the approach of a person or animal (that is, the "presence of a living organism"); at the same time, it determines whether the washing machine door is in the open state; if both conditions are met at the same time, the safety protection mechanism is triggered: the safety lock is activated to prevent the door from being closed or the program from being started; the remote control interface is disabled to avoid remote misoperation; and the protection state is automatically released after the organism leaves and the door is closed.
[0105] In a preferred embodiment, the specific control process includes:
[0106] S111: Using an infrared sensor or a TOF camera located near the door of the washing machine, detecting in real time whether there is a living organism in a preset area of the washing machine;
[0107] S112: Detecting the open / closed state of the washing machine door through a micro switch or a magnetic sensor on the door body;
[0108] S113: When a living organism is detected in a preset area of the washing machine and the washing machine door is open, the controller automatically activates the door safety lock to prevent the door from closing accidentally;
[0109] S114: At the same time, the controller cuts off the remote control communication channel and temporarily disables the remote control function of the washing machine through the smart terminal (such as a mobile phone app);
[0110] S115: When the organism leaves the preset area of the washing machine and the door is closed, the safety lock is automatically released and the remote control function is restored.
[0111] This method effectively prevents accidents caused by improper operation when children or pets are close to the washing machine, thereby improving the safety and intelligence level of washing machine use.
[0112] In another embodiment, the main controller is further configured to:
[0113] Detect whether the door switch control signal is received;
[0114] When the presence of a living organism is detected within a preset area of the washing machine and a switch control signal is received, the safety lock is activated and the remote control function is disabled.
[0115] Among them, the switch control signal includes the opening / closing door operation instructions issued by the user through physical buttons, touch screen, voice assistant or App, and disables the remote control function, such as blocking the opening / closing door operation instructions issued by the touch screen, voice assistant or App.
[0116] Specifically, the main controller is also used to:
[0117] When the door is detected to be in a closed state and the preset unlocking action is performed on the local operation panel, the remote control function is restored.
[0118] When the door is detected to be in a closed state, it is ensured that there are no living organisms inside; the preset unlocking action is to enter specific unlocking instructions or steps on the local operation panel to restore the remote control function, that is, to unblock remote control interfaces such as Wi-Fi and Bluetooth.
[0119] The specific working principle is: the washing machine control system continuously monitors the door status: whether it is in the closed state; at the same time, it monitors whether there is a user performing a preset unlocking action on the local operation panel: such as entering a specific password, pressing a specific combination of keys, scanning a fingerprint, etc.; when the following two conditions are met: the door is in the closed state; the user successfully performs the preset unlocking action on the local operation panel; the system releases the security protection mechanism: restores the remote control function, and allows control through mobile phone apps, voice assistants, etc.; optionally, a prompt sound or indicator light signal is issued to inform the user that the remote control function has been restored.
[0120] In an optional embodiment, the preset unlocking action is:
[0121] Press the Start button three times within the preset time on the local operation panel.

A preset timer of 1 or 1.5 seconds is used to determine whether the clicks are rapid and continuous. A triple press is defined as the user pressing the start button three times in a short period of time. For key detection, a microcontroller collects the start button press signal and uses a timer to record the time interval between the two presses. The microcontroller then determines whether the "three clicks + time window" condition is met. If so, it removes the WiFi or Bluetooth control shield and allows remote command responses.

[0125] In addition, the system can provide users with feedback on the unlocking success status through flashing LED lights, buzzer prompts, or text prompts on the display screen, ensuring transparent and controllable operations.
