[0050] In the related art, for a refrigerator with an ice maker, due to the complexity of the ice-making system, which includes an ice-off motor and a water pump, and the ice maker on the door also includes motor components such as a crushed ice motor and a dispenser, it is prone to failures during long-term use and is not easy to be detected. Currently, the fault diagnosis method for the ice maker is relatively single and mainly relies on temperature changes for judgment. However, this diagnosis method has obvious limitations and cannot accurately and comprehensively reflect the actual fault situation of the ice maker.

[0051] The embodiments of this application provide a refrigerator, a fault detection method, a fault detection device, and a storage medium thereof to solve the problem of inaccurate fault diagnosis of the existing ice maker of the refrigerator. The following will be described in conjunction with the attached Figures 1-5 for illustration.

[0052] The fault detection method of the refrigerator provided by the embodiments of this application can be applied to a refrigerator with an ice maker. Please refer to Figure 1 , Figure 1 which is a schematic flowchart of the fault detection method of the refrigerator provided by the embodiments of this application.

[0053] Referring to Figure 1 shown, the fault detection method of the refrigerator may include:

[0054] S101: Determine the number of ice-turning times of the ice maker;

[0055] Optionally, the ice-turning action of the ice maker can be monitored in real time by a sensor (such as a motion sensor or a photoelectric sensor) installed in the ice maker. Whenever the sensor detects an ice-turning action once, the control system counts once and records the data in the memory.

[0056] Exemplarily, during the counting process, the situation where the ice storage box is full is specifically excluded, that is, when the ice storage box is full, the ice-turning action counting is no longer performed.

[0057] S102: Obtain the installation type of the ice maker;

[0058] Optionally, the installation types of the ice maker can include different methods such as door-mounted and in-cabinet-mounted, and these installation types will affect the types of faults of the ice maker. The installation type identification can determine the specific installation type of the ice maker through the identification mechanism built into the control system or user settings.

[0059] S103: Determine the fault type of the ice maker based on the number of ice turning times and the installation type.

[0060] The control system comprehensively analyzes the stored data of the number of ice turning times and the installation type. Based on the analysis results, the control system judges the possible fault types of the ice maker. For example, if the number of ice turning times increases abnormally, it may indicate insufficient water pressure or airtightness failure, and the specific fault type is associated with the installation type of the ice maker.

[0061] In an optional embodiment, determining the fault type of the ice maker based on the number of ice turning times and the installation type includes: when the number of ice turning times is greater than the preset number and the installation type is the first type, determining that the fault type of the ice maker is insufficient water pressure fault; when the number of ice turning times is greater than the preset number and the installation type is the second type, determining that the fault type of the ice maker is airtightness failure.

[0062] It should be noted that in this embodiment, the first type is a door-mounted ice maker, that is, the ice maker is installed on the door body of the refrigerator, and the ice-making water is connected to an external water source through an external water pipe. The second type is an in-cabinet ice maker, that is, the ice maker is installed inside the refrigerator, and a water storage box is also provided inside the refrigerator to provide ice-making water, and the user can replenish water into the water storage box by manual watering.

[0063] When it is detected that the number of ice turning times is greater than the preset number and the installation type is door-mounted, the control system judges that the fault type of the ice maker is insufficient water pressure fault. The door-mounted ice maker relies on an external water source for water supply. If the water pressure is insufficient, it may cause the ice maker to malfunction, manifested as an abnormal increase in the number of ice turning times. Insufficient water pressure may be caused by external water source problems, water pipe blockage, water outage or poor connection, etc.

[0064] Once it is determined that the fault type is insufficient water pressure, the control system can prompt the user with specific fault information through the refrigerator's display screen, alarm device or user interface, etc. The prompt information can include the fault type, possible reasons (such as external water source problems, water pipe blockage, etc.) and recommended inspection or repair measures (such as checking the water source, cleaning the water pipe, etc.).

[0065] When the number of ice turning operations is greater than the preset number, and the installation type is the second type (installed inside the box), the system determines that the fault type of the ice maker is an airtightness fault and prompts the user to perform an airtightness check. When the ice maker inside the box is subjected to factory inspection, the normal operation of the system is checked by sequentially checking the power consumption of each electrical component during operation. However, the airtightness of each component cannot be detected. After filling the water storage box with water in this solution, an accurate airtightness check can be performed, and the detected fault code is prompted, which can detect airtightness problems in the structure or connection.

[0066] In an optional implementation, the method for determining the preset number includes: obtaining the maximum amount of ice produced per cycle m of the ice maker and the maximum ice storage capacity M of the ice storage box of the ice maker; determining the preset number based on the maximum amount of ice produced per cycle and the maximum ice storage capacity.

[0067] In this embodiment, the maximum amount of ice produced per cycle m represents the weight of the ice cubes that can be produced in each ice-making cycle when the ice maker is in a normal operating state. The average value of the ice cube weights measured in multiple ice-making cycles can be taken as the maximum amount of ice produced per cycle m. The maximum ice storage capacity M represents the total maximum weight of the ice cubes that can be stored when the ice storage box is full. The preset number can be M / m, which represents the number of ice-making cycles required for the ice storage box to reach the maximum ice storage capacity in a normal operating state. Through this calculation, a theoretically preset number value can be obtained.

[0068] Apply the calculated preset number to the fault detection system of the ice maker as a threshold for judging faults such as insufficient water pressure and airtightness faults. The system continuously monitors the number of ice turning operations of the ice maker and compares it with the preset number. If the number of ice turning operations exceeds the preset number, a fault prompt is triggered.

[0069] In some optional implementations, after the fault prompt, the preset number is adjusted and optimized in a timely manner according to the actual usage situation and user feedback to ensure the accuracy and reliability of fault detection.

[0070] In an optional implementation, after determining the number of ice turning operations of the ice maker, the fault detection method further includes: after each ice turning operation, obtaining the mass information of the ice storage box; determining the amount of ice produced per cycle of the ice maker based on the mass information; and sending a fault prompt message to the user when the amount of ice produced per cycle is lower than the preset amount of ice produced per cycle.

[0071] Optionally, a weight sensor can be installed below the ice storage box or at an appropriate position to continuously monitor the mass change of the ice storage box. After each ice turning operation is completed, the control system obtains the current mass information of the ice storage box from the weight sensor. Based on the mass information of the ice storage box, calculate the mass change before and after each ice turning operation, so as to determine the weight of the ice cubes produced in this ice-making cycle, that is, the amount of ice produced per cycle. Record the calculated amount of ice produced per cycle in the memory of the system for subsequent analysis and comparison.

[0072] According to the design parameters and actual tests of the ice maker, a reasonable preset ice production amount is set as a reference standard for normal ice making. Compare the single ice production amount calculated each time with the preset ice production amount. If the single ice production amount is lower than the preset ice production amount for multiple consecutive times, it is determined that the ice maker may have a fault.

[0073] In this embodiment, if it is found that the single ice production amount is lower than the preset ice production amount, the system can immediately analyze it, rather than waiting for the number of ice turning times to reach the preset number to prompt a fault, and can give an early warning.

[0074] By introducing the mass information of the ice storage box, the abnormal ice production amount of the ice maker can be detected more accurately, so as to timely discover potential faults and send fault prompt information in time, which helps users take measures in time to ensure the quality of ice and the stable operation of the ice maker.

[0075] In an alternative embodiment, after determining that the fault type of the ice maker is an airtightness fault, the method further includes: obtaining the flow information at the water pump outlet, and determining that the water pump has a fault when the flow information is less than the preset flow rate; and determining that the water delivery pipe has a fault when the flow information is greater than the preset flow rate.

[0076] In this embodiment, the water storage box is connected to the ice maker through a water pump and a water delivery pipe, and the water pump and the water delivery pipe transport the water in the water storage box to the ice maker for ice making.

[0077] After determining that the fault type of the ice maker is an airtightness fault, in order to more accurately locate the fault source, this alternative embodiment further introduces the flow information at the water pump outlet for diagnosis. By analyzing the flow information, it can be distinguished whether the airtightness fault is caused by the water pump itself or the water delivery pipe fault, thereby improving the pertinence and efficiency of maintenance.

[0078] Exemplarily, a flow sensor is installed at the water pump outlet for real-time monitoring of the water flow. The system regularly or real-time reads the data of the flow sensor to obtain the current flow information. If the detected flow information continuously falls below the preset flow threshold, it indicates that the water outlet capacity of the water pump is insufficient. The system accordingly determines that the water pump has a fault, which may be caused by water pump blockage, wear or motor failure, etc. At this time, a prompt message for water pump fault can be sent to the user, suggesting repair or replacement. If the detected flow information continuously exceeds the preset flow threshold, it indicates that there is a leak in the water delivery process. The system accordingly determines that the water delivery pipe has a fault, which may be caused by pipe rupture, loose joint or poor seal, etc., and sends a prompt message for water delivery pipe fault to the user, suggesting checking the pipe system.

[0079] In an alternative embodiment, in combination with Figure 2 and Figure 3As shown, determining the number of ice - turning times of the ice maker includes: incrementing the number of ice - turning times by one each time the ice maker turns the ice; and / or, when the freezer door of the refrigerator is detected to be opened, resetting the number of ice - turning times to zero; and / or, in response to the trigger signal of the placement switch of the ice storage box of the ice maker, resetting the number of ice - turning times to zero.

[0080] Exemplarily, a position sensor or a travel switch can be installed on the ice - turning mechanism of the ice maker to detect the ice - turning action. Each time the sensor detects the ice - turning action, the control system increments the internal ice - turning times counter by one, thereby updating the number of ice - turning times in real - time.

[0081] Optionally, a door switch sensor is installed on the freezer door of the refrigerator to detect the opening state of the door. When the sensor detects that the freezer door is opened, the control system receives the signal and resets the ice - turning times counter. This is because the user may be taking ice, and the number of ice - turning times needs to be reset to reflect the new ice - making cycle.

[0082] Optionally, a placement switch is installed at the placement position of the ice storage box to detect whether the ice storage box is placed or removed. When the placement switch is triggered (for example, the user removes or replaces the ice storage box), the control system receives the signal and resets the ice - turning times counter. This is also to ensure that the number of ice - turning times can reflect the new ice - making cycle after the ice storage box is re - placed.

[0083] Through multiple sensors and logical judgments, accurate recording and timely resetting of the number of ice - turning times are ensured, providing reliable data for fault diagnosis. Multiple resetting methods can be selected and combined according to different user usage habits and scenarios, improving the adaptability of the system.

[0084] In an alternative embodiment, determining the number of ice - turning times of the ice maker includes: in the case where the installation type is the first type, resetting the number of ice - turning times in response to the trigger signal of the dispenser of the ice maker; in the case where the installation type is the second type, obtaining the water level height of the water storage box of the ice maker, and resetting the number of ice - turning times when the water level height is lower than the preset height.

[0085] In this embodiment, to calculate the number of ice - turning times more precisely, it is optimized according to the characteristics of different installation types. A signal sensor is installed on the dispenser (ice - taking switch) of the ice maker on the door. After the user presses the ice - taking switch, the sensor emits a trigger signal. After the control system receives the trigger signal of the dispenser, it resets the ice - turning times counter. This is because after the user takes ice, the ice maker will start a new ice - making cycle, and the number of ice - turning times needs to be reset to reflect the new state.

[0086] When the installation type of the ice maker is the second type, a water level sensor can be installed in the water storage box of the ice maker. The water level sensor monitors the water level height in the water storage box in real time, and the control system regularly obtains the water level height information of the water storage box. When the water level height is lower than the preset height, the system determines that the water storage box may be emptied or replaced. At this time, the ice turning times counter is cleared, and the user is prompted to add water in time. This ensures that at the beginning of a new ice making cycle, the ice turning times can be counted from zero, reflecting the actual ice making situation.

[0087] The fault detection method of the refrigerator provided by the embodiment of the present application includes determining the ice turning times of the ice maker; obtaining the installation type of the ice maker; and determining the fault type of the ice maker based on the ice turning times and the installation type. By comprehensively analyzing the ice turning times and the installation type, this method can more accurately identify the fault type of the ice maker, avoid the limitations of the traditional temperature diagnosis method, and effectively improve the efficiency and accuracy of fault detection.
