[0052] Figure 5 This is a schematic diagram of the structure of a washing machine provided in an embodiment of the present invention. Detailed Implementation

[0053] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0054] It should be noted that the motor, as the main power component of the washing machine, determines whether the washing process can proceed normally and the safety of the mechanical movements. Therefore, it is particularly important to be able to detect motor abnormalities in a timely manner and correct and handle them.

[0055] There are many reasons why a washing machine motor might malfunction: a faulty motor itself, damaged wiring, a problem with the control board's motor drive mechanism, or a foreign object blocking the impeller. These can all cause abnormal motor operation during the washing process. While motor malfunctions usually don't prevent the washing machine from continuing to run, they can result in clothes not being properly cleaned, reducing the user experience. A foreign object blocking the motor can cause overload, potentially damaging the motor itself and creating a safety hazard.

[0056] Most washing machines on the market currently lack effective detection of motor malfunctions. To address this, this invention improves machine safety and user experience by detecting motor malfunctions and promptly correcting and alarming them.

[0057] Figure 1 This is one of the flowcharts illustrating a method for handling motor malfunctions in a washing machine according to an embodiment of the present invention. (Refer to...) Figure 1 This invention provides a method for handling motor malfunctions in a washing machine, which may include the following steps:

[0058] S1. Determine that a motor malfunction has occurred during the current washing process of the washing machine;

[0059] S2. Control the washing machine to perform correction processing;

[0060] S3. If the correction process performed by the washing machine fails, control the washing machine to shut down the target load.

[0061] In this embodiment of the invention, the operating status of the motor can be monitored in real time by setting a Hall effect detection circuit or other means. Motor anomaly monitoring can be, but is not limited to, the following: during the operation of a washing machine in a certain washing mode, if the monitored motor operating parameters do not match the preset parameter conditions corresponding to the current washing process, it is determined that the motor is abnormal, and the washing machine is confirmed to have experienced a motor malfunction. For example, if the current washing process is a spin-drying process, then during this process, the motor's rotation parameters should meet certain parameter conditions (such as acceleration, rotational speed, maximum speed, etc.). If the actual measured motor operating parameters exceed the set parameter conditions, it is determined that the washing machine has experienced a motor malfunction. For example, if the motor is detected not rotating for m seconds during the spin-drying process, it is determined that the washing machine has experienced a motor malfunction.

[0062] It should be noted that when a motor malfunction is detected in the washing machine, it is not always due to a motor failure or wiring fault. More often, it is caused by clothes or foreign objects becoming stuck inside the washing machine. For situations like foreign object obstruction, corrective measures can resolve the motor malfunction to some extent. Therefore, in this embodiment of the invention, when a motor malfunction is detected, the load is not immediately shut down or an alarm is triggered as if it were a motor failure. Instead, the washing machine is first controlled to attempt a corrective action. If the corrective action fails, then further processing is performed as if it were a motor failure. The corrective action method can be pre-configured based on corrective testing for foreign object obstruction. For example, the currently running washing mode can be changed to another mode, or the washing machine can be controlled to enter a pre-set specific operating mode for corrective action.

[0063] After the correction process, it is determined again whether the previously detected motor malfunction has been resolved. If the motor malfunction is caused by foreign object obstruction, the problem can likely be resolved by running the preset correction program. The success / failure of the correction process is detected by continuing to run the washing mode corresponding to the current washing process and then using the same method and judgment conditions to determine if the motor is still malfunctioning. If a motor malfunction is still detected, it indicates a motor failure or other issues requiring manual intervention. To improve the safety of the washing machine operation, the main load is shut off when a motor failure is confirmed. Simultaneously, by preventing the washing machine from continuing to run under motor malfunction conditions, the problem of incomplete washing is avoided, improving the user experience.

[0064] The washing machine motor malfunction handling method of this invention improves the safety of washing machine operation by monitoring the motor status of the washing machine in real time during the washing process, correcting the motor malfunction when it is detected, and shutting down the load if the correction fails.

[0065] In one embodiment, step S1 may include:

[0066] S11. Determine that the current washing process of the washing machine is a washing process, and determine that the motor has not rotated within a preset number of operating cycles, and determine that the washing machine has experienced a motor malfunction during the current washing process;

[0067] And / or, S12, determine that the current washing process of the washing machine is a spin-drying process, and determine that the motor has not rotated within a preset running time, and determine that the washing machine has experienced a motor malfunction during the current washing process.

[0068] In this embodiment of the invention, to improve the accuracy of motor anomaly monitoring, the corresponding motor anomaly judgment conditions need to be different for different washing modes. It is understood that in washing mode, the washing machine operates by alternating between forward rotation, stop, reverse rotation, and stop, while in spin-drying mode, it rotates continuously in the same direction. Therefore, for motor anomaly monitoring during the washing process, n sets of cycles can be selected as the time window for anomaly judgment, for example, 48 sets of cycles, where each set of cycles can include four processes: forward rotation, stop, reverse rotation, and stop. For motor anomaly monitoring during spin-drying mode, a duration of m seconds can be selected as the time window for anomaly judgment. In this embodiment of the invention, if no motor rotation is detected within the duration of n sets of cycles or m seconds, it is determined that a motor anomaly has occurred in the current washing process. In other embodiments, motor anomaly monitoring can also be performed based on other preset parameter conditions.

[0069] The washing machine motor malfunction handling method of this invention improves the accuracy of motor malfunction monitoring by selecting different motor malfunction judgment conditions according to different washing processes.

[0070] In one embodiment, step S2 may include:

[0071] S21. Determine the target washing mode based on the current washing mode corresponding to the current washing process, and control the washing machine to run the target washing mode for correction processing;

[0072] The target washing mode is a washing mode that is different from the current washing mode among the multiple preset washing modes of the washing machine.

[0073] In this embodiment of the invention, motor malfunctions can be corrected by changing the current washing machine mode. For example, if the current washing process corresponds to the spin-dry mode, and a motor malfunction is detected during the operation of the washing mode, the washing mode can be switched to attempt to correct the motor malfunction.

[0074] It is understandable that since the motors operate in different ways in different washing modes, changing the current washing mode is equivalent to changing the motor's operating mode. Changing the motor's operating mode can effectively correct motor malfunctions.

[0075] At the same time, by changing the current washing mode, the shape of the clothes inside the washing machine drum can be changed. For example, during the spin-drying process, due to the continuous high-speed rotation, clothes or foreign objects are easily stuck. If the washing mode is changed, the state of the objects inside the washing drum can be changed through the water soaking process in this mode, thereby effectively solving the problem of foreign objects getting stuck.

[0076] It should be noted that correcting motor malfunctions by changing the washing mode eliminates the need for additional correction procedures, simplifying the internal processing of the washing machine. This improves the machine's operational reliability and saves on development and maintenance costs.

[0077] The motor malfunction handling method for washing machines in this embodiment of the invention corrects motor malfunctions by controlling the washing machine to change the current washing mode, which simplifies the logical implementation of the correction process and thus improves the efficiency of motor malfunction correction.

[0078] In one embodiment, step S2 may include:

[0079] S22. Determine the target operating parameters of the correction process based on the current washing process, and control the washing machine to execute the correction process to perform correction processing;

[0080] The target operating parameters include at least one of the following: motor rotation acceleration, maximum motor speed, motor start-stop cycle, water supply time, drainage time, water supply volume, and drainage volume.

[0081] In this embodiment of the invention, motor malfunctions can be corrected by running a pre-configured specific correction program. This correction program is configured after simulating foreign object embedding scenarios and conducting extensive experimental tests for such scenarios, thereby improving the effectiveness of correcting motor malfunctions. It is understood that by changing the motor's output torque, speed, cycle time, and operations such as water filling and draining, the problem of foreign object embedding can be resolved to a certain extent. In this embodiment of the invention, the operation mode of the correction program is determined by pre-configuring one or more of the following: motor rotation acceleration, maximum motor speed, motor start-stop cycle time, water filling time, draining time, water filling volume, and draining volume. Then, when a motor malfunction is detected, the washing machine is controlled to run this correction program to correct the motor malfunction. It should be noted that because the correction program is configured after extensive experiments simulating actual conditions, it is highly targeted at correcting foreign object embedding scenarios in real-world use, effectively improving the effectiveness of motor malfunction correction.

[0082] The washing machine motor abnormality handling method of this invention determines the target operating parameters of the correction process based on the operating parameters of the current washing process, so as to correct the motor abnormality by running a targeted correction process, thereby improving the effectiveness of the correction process, reducing the probability of judging it as a motor failure, and thus improving the user experience.

[0083] In one embodiment, after step S1 and before step S2, the following step may also be included:

[0084] S201. Determine that the washing machine is in a stationary state.

[0085] It's important to note that to improve the effectiveness and reliability of the washing machine's corrective processing, after detecting a motor malfunction, it's necessary to ensure the washing machine is in a stationary state before initiating corrective measures. For example, if a motor malfunction occurs during a wash cycle, it's crucial to ensure the washing machine has stopped washing and there are no ongoing water filling, draining, or motor operation activities before proceeding with corrective measures. Running the corrective program without confirming the washing machine is in a stationary state may allow previously run wash cycles to influence the current corrective process, reducing its success rate. Furthermore, the interaction between the current wash cycle and the corrective program could potentially lead to unavoidable malfunctions, resulting in problems more serious than the motor malfunction itself. Therefore, ensuring the washing machine is in a stationary state before running the corrective program enhances the effectiveness of the corrective process and improves the safety and reliability of the washing machine's operation.

[0086] The washing machine motor malfunction handling method of this invention suspends the washing machine before controlling it to make corrections, thus avoiding the correction process being affected by the current washing process and improving the success rate of the correction process.

[0087] In one embodiment, determining that the corrective processing performed by the washing machine has failed includes:

[0088] Determine the current washing mode corresponding to the current washing process, and control the washing machine to re-run the current washing mode;

[0089] It is determined that a motor malfunction occurred during the operation of the current washing mode in the washing machine, and the corrective processing performed by the washing machine has failed.

[0090] It should be noted that after the correction process, it is necessary to re-determine whether the previously detected motor abnormality has been corrected and resolved. If the motor abnormality is caused by foreign object jamming, etc., running the preset correction process will likely resolve this type of motor abnormality. In this embodiment of the invention, the success / failure detection of the correction process can be achieved by continuing to run the washing mode corresponding to the current washing process, and then determining whether the motor is abnormal using the same method and judgment conditions. If the motor abnormality is still detected, it indicates that the motor abnormality is a motor malfunction or other problem, requiring manual intervention. At this time, an alarm is issued to prompt the user to handle the washing machine's motor malfunction in a timely manner. At the same time, in order to improve the safety of the washing machine operation, the main load is shut down when a motor malfunction is confirmed to avoid safety hazards caused by motor abnormalities. In addition, by shutting down the relevant load in a timely manner when a motor malfunction is confirmed, the washing machine is prevented from continuing to run under motor abnormality conditions, thereby ultimately avoiding the situation where the washing machine does not wash clothes cleanly, and improving the user experience.

[0091] The washing machine motor malfunction handling method of this invention, after controlling the washing machine to perform correction processing, re-runs the washing mode in which the motor malfunction was detected, and re-detects whether the motor malfunction has occurred, thereby accurately determining whether the correction processing for the motor malfunction was successful.

[0092] In one embodiment, step S3 may specifically include:

[0093] If the corrective processing performed by the washing machine fails, control the washing machine to shut down the target load and issue a motor fault alarm;

[0094] The motor fault alarm includes at least one of the following:

[0095] Based on the buzzer issuing a motor fault alarm signal;

[0096] The indicator light triggers a motor fault alarm signal.

[0097] Send motor fault alarm information to the target terminal.

[0098] In this embodiment of the invention, the target terminal can be a mobile terminal such as a smartphone. The washing machine can be connected to Wi-Fi, allowing an app to push notifications of a motor malfunction to the mobile terminal, enabling the user to promptly detect the motor malfunction and take appropriate measures. Alternatively, the target terminal can be a remote information terminal connected to the washing machine via wired or wireless communication, such as a terminal with display or audible / visual alarm functions. This remote terminal can be placed in a prominent location, such as the user's living room, to facilitate timely detection of the motor malfunction. Since washing machines are typically installed in places not frequently noticed by users, such as balconies or bathrooms, when the user is far away from the washing machine (e.g., in the living room or outdoors), a buzzer or indicator light alone may not be sufficient to promptly transmit a motor malfunction signal. Therefore, upon determining that a motor malfunction has occurred, one or more methods can be configured to provide a motor malfunction alarm, such as sounding a buzzer, illuminating an indicator light, triggering an audible / visual alarm, or pushing notifications to a remote target terminal.

[0099] The washing machine motor fault handling method of this invention provides motor fault alarms in one or more ways so that users can promptly detect motor faults in the washing machine, thereby further improving the safety of washing machine operation.

[0100] Please see Figure 2-3 Based on the above solution, to facilitate a better understanding of the washing machine motor malfunction handling method provided in the embodiments of the present invention, specific examples are listed below for detailed explanation:

[0101] In this embodiment of the invention, a Hall effect detection circuit can be added to the washing machine to detect the motor status throughout the washing process. If an abnormal motor speed is detected, it is corrected first. If the correction is unsuccessful and the motor is still abnormal, all loads are shut down and a motor abnormality alarm is triggered, awaiting manual intervention to resolve the problem.

[0102] It should be noted that the main causes of motor malfunctions include: motor failure, related circuit failure, failure of the computer board controlling the motor drive, or foreign object jamming. Motor malfunctions caused by foreign object jamming can be resolved to some extent through corrective measures. However, motor malfunctions caused by excessive jamming or other reasons cannot be resolved by the washing machine's automatic correction system. In such cases, an alarm should be triggered to alert the user to prevent further unnecessary damage.

[0103] In the scheme for detecting motor abnormalities in this embodiment of the invention, using a Hall sensor as the main detection device to detect the motor status is a good choice. This embodiment of the invention utilizes the Hall sensor to detect the motor's rotational speed to determine the motor's operating status. It can be understood that the motor's operation mainly occurs in two processes: the washing process and the spin-drying process. Different detection and judgment conditions are selected for different processes.

[0104] like Figure 2 As shown, the motor's operating status is monitored throughout the washing process. Users can select forward rotation, stop, reverse rotation, and stop, which constitutes one cycle. If the motor is not detected to rotate within n cycles (n cycles are selected through extensive testing), the motor is considered abnormal, the washing process is immediately stopped, and corrective measures are taken.

[0105] After correction, continue running. Similarly, if the motor is still not detected after n cycles, shut down all loads and issue a motor malfunction alarm.

[0106] like Figure 3 As shown, the motor's operating status is monitored throughout the dehydration process. If the motor is not detected for m seconds (the duration of m seconds was selected after extensive testing), it is considered an abnormality, and the dehydration is immediately stopped for correction. After correction, the process continues. If the motor is still not detected for m seconds, all loads are shut off, and a motor abnormality alarm is triggered.

[0107] It should be noted that the n sets of cycles and m seconds mentioned above vary depending on the product model, product structure, and operating principle. For example, in this embodiment of the invention, n sets can be set to 48 sets, and m seconds can be set to 30 seconds. The overall motor anomaly detection and processing logic is basically as described above; the detailed processing for other different models can be configured differently according to actual needs.

[0108] Compared with the prior art, the embodiments of the present invention can effectively detect the operating status of the motor and make timely corrections or alarms, thereby improving the safety of the washing machine and enhancing the user experience.
