[0001] This application is based on the Chinese patent application with application number 202311183753.6 and application date September 13, 2023, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into this application as a reference. Technical Field

[0003] To meet the daily ice needs of ordinary households without specialized ice makers and to satisfy consumers' increasing demand for multifunctional home appliances, refrigerators are now equipped with ice-making functions. However, when using this function, it is necessary to monitor the ice-making status of the refrigerator.

[0004] To detect the ice-making status of a refrigerator's ice-making function, related technologies typically install a camera inside the refrigerator to capture images or videos of ice cubes in the ice storage device. The captured images or videos are then displayed on the refrigerator's display screen, allowing the user to manually determine the ice-making status. However, this manual determination of the ice-making status requires the user to check promptly. If the user fails to check promptly, it is difficult to accurately determine the ice-making status of the refrigerator.

[0042] A refrigerator 1 provided by an embodiment of the present disclosure is shown in Figures 1, 7 and 8. The refrigerator 1 includes an ice storage device 10, an ice making device 20 and an electronic control device 30. The ice storage device 10 is configured to store ice cubes. The ice making device 20 includes an ice detection rod 201, a motor 202 and an ice turner 203. The ice detection rod 201 is configured to detect ice cubes in the ice storage device 10, the motor 202 is configured to control the movement of the ice detection rod 201, and the ice turner 203 is configured to turn ice to pour ice cubes into the ice storage device 10.

[0043] Optionally, the ice making device 20 further includes an ice making box 205 for making ice cubes.

[0049] Optionally, the refrigerator 1 further includes an ambient light 50 for indicating different ice-making states of the refrigerator 1 by having the ambient light 50 be in different states.

[0050] In conjunction with the refrigerators shown in Figures 1, 7, and 8, the present disclosure provides a method for detecting the ice-making state of the refrigerator. As shown in Figure 2, the method includes:

[0051] S21, after the ice turning device turns over the ice, the processor controls the ice detection rod to move from the initial position toward the bottom of the ice storage device.

[0052] The processor controls the rotation of the motor to control the operation of the ice probe, so that the ice probe moves from an initial position toward the bottom of the ice storage device.

[0053] S22, the processor obtains ice probe detection information and motor current of the ice probe during its movement.

[0054] S23, the processor determines the ice-making state of the refrigerator according to the detection information of the ice-detecting rod and the motor current.

[0055] In this embodiment, after the ice turning device turns ice, the ice detection rod is controlled to move from its initial position toward the bottom of the ice storage device to detect the ice storage status in the ice storage device. This prevents the ice making device from continuing to make ice when the ice storage device is full of ice, without manual intervention. The ice detection rod detection information and the motor current can accurately determine the specific obstruction of the ice detection rod during movement. Based on the specific obstruction, the ice making status can be accurately determined, thereby improving the accuracy of detecting the ice making status of the refrigerator.

[0056] Optionally, the processor determines the motor current as follows: the processor obtains multiple detected currents of the motor during the movement of the ice probe. The processor uses the maximum current among the multiple detected currents as the motor current. By selecting the maximum current as the motor current, the movement of the ice probe can be promptly determined, thereby promptly understanding the ice-making status of the refrigerator.

[0057] Optionally, the processor determines the motor current by calculating an average of multiple detected currents and using the average as the motor current. Using the average as the motor current allows for a comprehensive understanding of the motor current, thereby providing a holistic view of the refrigerator's ice-making status.

[0058] Optionally, the processor determines the motor current as follows: the processor obtains a detected current when the ice probe stops moving and uses the detected current at that moment as the motor current. Because this detected current corresponds to the moment the ice probe stops, i.e., the ice probe's stopped position, using this detected current as the motor current allows for a more reasonable determination of the refrigerator's ice-making status.

[0059] Optionally, the ice probe detection information includes ice probe detection time. Since the ice probe detection time can accurately reflect the movement of the ice probe, the ice probe detection time is used as the ice probe detection information.

[0060] Optionally, the processor determines the ice probe detection duration as follows: the processor determines a target position. The processor obtains a first displacement duration of the ice probe from an initial position to the target position. The processor uses the first displacement duration as the ice probe detection duration.

[0061] For example, the target position is located at a position 1 / 4 of the way down from the opening of the ice turning device. This target position indicates that the ice making state is not full.

[0062] Illustratively, the ice probe moves at a constant speed during the movement.

[0063] Optionally, the processor determines the ice probe detection duration in the following manner: obtaining a second displacement duration of the ice probe from the initial position to the blocking position, and using the second displacement duration as the ice probe detection duration.

[0064] The blocking position represents the corresponding position when the ice probe is blocked.

[0065] Optionally, the processor determines the ice-making state of the refrigerator based on the ice-probe detection information and the motor current, including: the processor determines that the ice-making state of the refrigerator is a not-full-ice state when the ice-probe detection time is greater than or equal to a preset time, and the motor current is less than or equal to a preset current. The processor determines that the ice-making state of the refrigerator is an abnormal ice-making state when the ice-probe detection time is less than a preset time, and the motor current is less than or equal to a preset current. Alternatively, the processor determines that the ice-making state of the refrigerator is an abnormal ice-making state when the ice-probe detection time is greater than or equal to a preset time, and the motor current is greater than a preset current. The processor determines that the ice-making state of the refrigerator is a full-ice state when the ice-probe detection time is less than a preset time, and the motor current is greater than a preset current.

[0066] Exemplarily, the preset duration is set to [7s (seconds), 10s].

[0067] Exemplarily, the preset current is set to [340 mA (milliamperes), 380 mA].

[0068] In this embodiment, the ice-making status of the refrigerator is determined by the duration of ice-probe detection and the motor current. If the ice-probe detection duration is greater than or equal to a preset duration and the motor current is less than or equal to a preset current, the ice-probe movement duration is longer and unobstructed, indicating that the ice-probe has reached at least a preset position, thereby confirming that the ice-making status of the refrigerator is not full. If the ice-probe detection duration is less than the preset duration and the motor current is less than or equal to the preset current, the ice-probe cannot continue to move and detect without encountering an object blocking its movement, thus confirming that the ice-making status is abnormal. If the ice-probe detection duration is greater than or equal to the preset duration, the ice-probe movement duration is longer, but due to the high motor current, this is also confirmed as an ice-making abnormality. If the ice-probe detection duration is less than the preset duration and the motor current is greater than the preset current, the ice-probe is blocked before reaching the preset position, thus confirming that the ice-making status is full.

[0069] Optionally, the ice probe detection information includes the ice probe detection distance.

[0070] Optionally, the processor determines the ice probe detection distance in the following manner: the processor determines a blocking position. The processor obtains a target distance of the ice probe from an initial position to the blocking position. The processor uses the target distance as the ice probe detection distance.

[0071] Optionally, the processor determines the ice-making state of the refrigerator based on the ice-probe detection information and the motor current, including: the processor determines that the ice-making state of the refrigerator is a not-full-ice state when the ice-probe detection distance is greater than or equal to a preset distance and the motor current is less than or equal to a preset current. The processor determines that the ice-making state of the refrigerator is an abnormal ice-making state when the ice-probe detection distance is less than a preset distance and the motor current is less than or equal to a preset current. Alternatively, the processor determines that the ice-making state of the refrigerator is an abnormal ice-making state when the ice-probe detection distance is greater than or equal to a preset distance and the motor current is greater than a preset current. The processor determines that the ice-making state of the refrigerator is a full-ice state when the ice-probe detection distance is less than a preset distance and the motor current is greater than a preset current.

[0072] Exemplarily, the preset distance is set to 1 / 4 to 3 / 10 of the height of the ice storage device.

[0073] In this embodiment, the ice-making status is determined based on the ice-probe detection distance and motor current. If the ice-probe detection distance is greater than or equal to a preset distance and the motor current is less than or equal to a preset current, the ice-probe has moved a considerable distance and was not obstructed during movement. Therefore, it can be determined that the ice-probe has moved at least the preset distance, thereby confirming that the ice-making status of the refrigerator is not full. If the ice-probe detection distance is less than a preset time duration, the ice-probe has moved a short distance, but the motor current is low. This indicates that the ice-probe has not encountered an object blocking its movement and is unable to continue moving and detecting. Therefore, in this case, an ice-making abnormality is determined. If the ice-probe detection distance is greater than or equal to a preset time duration, the ice-probe has moved a considerable distance, but the motor current is high. Therefore, in this case, an ice-making abnormality is also determined. If the ice-probe detection distance is less than a preset distance and the motor current is greater than a preset current, the ice-probe has been blocked before reaching the target position. Therefore, in this case, the ice-making status is determined to be full.

[0074] Optionally, the ice probe detection information includes ice probe detection time and ice probe detection distance.

[0075] Optionally, the processor determines the ice-making state of the refrigerator based on the ice probe detection information and the motor current, including: the processor determining that the ice-making state of the refrigerator is a partially full ice state when the ice probe detection distance is greater than or equal to a preset distance, the ice probe detection time is greater than or equal to a preset time, and the motor current is less than or equal to a preset current. The processor determines that the ice-making state of the refrigerator is an abnormal ice-making state when the ice probe detection distance is less than a preset distance, the ice probe detection time is less than a preset time, and the motor current is less than or equal to a preset current. Alternatively, the processor determines that the ice-making state of the refrigerator is an abnormal ice-making state when the ice probe detection distance is greater than or equal to a preset distance, the ice probe detection time is greater than or equal to a preset time, and the motor current is greater than a preset current. The processor determines that the ice-making state of the refrigerator is a fully full ice state when the ice probe detection distance is less than a preset distance, the ice probe detection time is less than a preset time, and the motor current is greater than a preset current.

[0076] In this embodiment, if the ice probe's detection distance is greater than or equal to a preset distance, the ice probe's detection duration is greater than or equal to a preset duration, and the motor current is less than or equal to a preset current, further indicating that the ice probe has moved a long distance and duration and has not been blocked during movement, the refrigerator is determined to be in a partially full ice state. If the ice probe's movement duration and distance are short, the motor current is low, indicating that the ice probe has not encountered an object blocking its movement and is unable to continue detecting, thus determining an abnormal ice making state. If the ice probe's movement duration and distance are long, but the motor current is high, further determining an abnormal ice making state. If the ice probe's detection distance is less than a preset distance, the ice probe's detection duration is less than a preset duration, and the motor current is greater than a preset current, further indicating that the ice probe has been blocked before reaching the target position. Therefore, in this case, the ice making state can be determined to be fully iced. The ice probe's detection duration, distance, and motor current are combined to determine the refrigerator's ice making state, further improving the accuracy of the determination result.

[0077] As shown in FIG3 , the embodiment of the present disclosure provides another method for detecting the ice making state of a refrigerator. The method includes:

[0078] S301, after the ice turning device turns the ice, the processor controls the ice detection rod to move from the initial position toward the bottom of the ice storage device.

[0079] S302: The processor obtains ice probe detection information and motor current of the ice probe during its movement.

[0080] S303: The processor determines the ice-making state of the refrigerator according to the detection information of the ice-detecting rod and the motor current.

[0081] S304: When the ice-making state of the refrigerator is not full of ice, the processor controls the ice turning device to perform an ice turning operation.

[0082] S305: When the refrigerator is in an abnormal ice-making state, the processor controls the ice turning device to stop the ice turning operation and prompts an ice-making device failure message.

[0083] S306: When the refrigerator is full of ice, the processor controls the ice turning device to stop turning the ice.

[0084] In this embodiment, the ice turning device is controlled to perform different operations depending on the ice making state. If the ice box is not full, indicating that ice making needs to continue, the ice turning device is controlled to turn the ice, allowing ice making to continue. If ice making is abnormal, indicating a malfunction in the ice making device, the ice turning device is controlled to stop turning the ice and notify the user of the fault, allowing for prompt after-sales repair. If the ice box is full, the ice turning device is controlled to stop turning the ice to prevent ice overflow, which could waste ice and damage refrigerator components.

[0085] The ice-making device fault information includes: motor fault and gear fault.

[0086] For example, the processor determines that the ice-making device fault information is a gear fault if the ice-detecting rod detection time is less than a preset time and the motor current is less than or equal to a preset current. The processor determines that the ice-making device fault information is a motor fault if the ice-detecting rod detection time is greater than or equal to a preset time and the motor current is greater than a preset current.

[0087] In this embodiment, if the ice probe detection duration is less than the preset time, it indicates that the ice probe movement duration is short. However, the motor current is low at this time, indicating that the ice probe has not touched an object blocking the movement of the ice probe and cannot continue to move for detection. Therefore, in this case, it is determined that the gear is faulty. If the ice probe detection duration is greater than or equal to the preset time, it indicates that the ice probe movement duration is long. However, since the motor current is high at this time, it is determined that the motor is faulty.

[0088] For example, the processor determines that the ice-making device fault information is a gear fault if the ice-detecting rod detection distance is less than a preset distance and the motor current is less than or equal to a preset current. The processor determines that the ice-making device fault information is a motor fault if the ice-detecting rod detection distance is greater than or equal to a preset distance and the motor current is greater than a preset current.

[0089] In this embodiment, if the ice probe's detection distance is less than the preset distance, it indicates that the ice probe has moved a short distance. However, the motor current is low at this time, indicating that the ice probe has not touched an object blocking its movement and is unable to continue moving and detecting. Therefore, in this case, it is determined that the gear is faulty. If the ice probe's detection distance is greater than or equal to the preset distance, it indicates that the ice probe has moved a long distance. However, since the motor current is high at this time, it is determined that the motor is faulty.

[0090] For example, the processor determines that the ice-making device fault information is a gear fault if the ice-probe detection distance is less than a preset distance, the ice-probe detection duration is less than a preset duration, and the motor current is less than or equal to a preset current. The processor determines that the ice-making device fault information is a motor fault if the ice-probe detection distance is greater than or equal to a preset distance, the ice-probe detection duration is greater than or equal to a preset duration, and the motor current is greater than a preset current.

[0091] In this embodiment, if the ice probe moves for a short time and a short distance, the motor current is low, indicating that the ice probe has not touched any object blocking its movement and cannot continue to move and detect, thus determining that a gear failure has occurred. If the ice probe moves for a long time and a long distance, but the motor current is high, then a motor failure can be determined.

[0092] In the above embodiment, the specific fault condition of the ice-making device is further determined by detecting the information of the ice probe and the motor current. The specific fault condition of the ice-making device facilitates the user to know the fault condition and perform after-sales maintenance, thereby improving maintenance efficiency.

[0093] Optionally, the processor prompts the ice-making device failure information by different states of the ambient light. In this way, the user does not need to be close to the refrigerator to know the current ice-making status of the refrigerator, which is more convenient and intuitive.

[0094] Optionally, the processor prompts the ice-making device fault information in a manner including prompting through information displayed on a display screen. In this way, the ice-making status of the refrigerator known to the user is more accurate and detailed.

[0095] Optionally, the processor prompts the ice-making device fault information in a manner including prompting through different states of the ambient light and prompting through information displayed on the display screen. In this way, the display effect of the result is not only convenient and intuitive, but also more accurate and detailed, which can meet the user's needs.

[0096] As shown in FIG4 , the embodiment of the present disclosure provides another method for detecting the ice making state of a refrigerator. The method includes:

[0097] S401, after the ice turning device turns the ice, the processor controls the ice detection rod to move from the initial position toward the bottom of the ice storage device.

[0098] S402: The processor obtains ice probe detection information and motor current of the ice probe during its movement.

[0099] S403: The processor determines the ice-making state of the refrigerator according to the detection information of the ice-detecting rod and the motor current.

[0100] S404: When the ice-making state of the refrigerator is not full of ice, the processor controls the ice turning device to perform an ice turning operation.

[0101] S405: The processor controls the ambient light to be in a constant on state.

[0102] S406: When the refrigerator is in an abnormal ice-making state, the processor controls the ice turning device to stop the ice turning operation and prompts an ice-making device failure message.

[0103] S407: The processor controls the ambient light to be in a flashing state.

[0104] S408: When the refrigerator is full of ice, the processor controls the ice turning device to stop turning the ice.

[0105] S409, the processor controls the ambient light to be in the off state.

[0106] In this embodiment, the ambient light is controlled to display different states of the refrigerator's ice-making status. When the user observes that the ambient light is constantly on, it indicates that the ice box is not full and ice making needs to continue. When the user observes that the ambient light is flashing, it indicates that the ice making is abnormal and the ice-making device is malfunctioning. When the ambient light is off, it indicates that the ice box is full and ice making is no longer necessary. This allows the user to intuitively obtain ice-making status information.

[0107] Optionally, the processor controlling the ambient light to be in a flashing state includes: the processor controlling the ambient light to flash at a first flashing frequency when the ice-making device fault state includes a gear fault; and controlling the ambient light to flash at a second flashing frequency when the ice-making device fault state includes a motor fault.

[0108] The absolute value of the difference between the first flickering frequency and the second flickering frequency is greater than or equal to a preset difference. For example, the preset difference is greater than 4 times per second.

[0109] In this embodiment, different fault states of the ice-making device are distinguished by setting a first flickering frequency and a second flickering frequency with a larger absolute value of the difference between them.
