[0044] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0045] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0046] Smart refrigerators must undergo factory inspection before leaving the factory. In the prior art, factory inspection of smart refrigerators requires manual button operation to turn on the power, and the inspection efficiency is low. In addition, users are required to conduct a self-inspection when they turn on the power for the first time after buying the refrigerator home, which may result in refrigeration for the first few minutes or no cooling at variable temperatures, affecting the user experience.

[0047] In view of the technical problems of the prior art, the present invention provides a method for detecting refrigerators before they leave the factory. The present invention provides a method for quickly detecting refrigerator failures in the factory, including: identifying the refrigerator model of the refrigerator to be detected, determining the mainboard and detection program corresponding to the refrigerator model; powering on the refrigerator to be detected to execute the detection program, detecting the power of each small load one by one within 1 minute, and inserting a sensor to detect the temperature of the sensor inside the refrigerator after the detection is completed; if the difference between the ambient temperature and the temperature of the internal sensor is within the preset temperature difference range, the refrigerator to be detected is qualified, otherwise, the refrigerator to be detected is unqualified. Through the technical solution of the present invention, it is possible to see whether each load is working normally and whether the refrigerator meets the refrigeration requirements through power, and it is possible to quickly and effectively detect the performance and status of the refrigerator as a whole, and judge whether the refrigerator to be detected is qualified in a short time, and it is easy to operate, thereby improving the efficiency of refrigerator factory detection and the accuracy of detection.

[0048] like Figure 1 As shown, a refrigerator factory inspection method according to Embodiment 1 of the present invention comprises the following steps:

[0049] Step S100: When the factory inspection is performed and it is detected that the refrigerator is connected to the power supply, the control automatically starts the factory inspection:

[0050] In the embodiment of the present invention, the factory inspection of a smart refrigerator is used as an example for explanation. In the specific implementation, the present invention pre-sets a factory inspection program on each refrigerator for performing factory inspection on the refrigerator. During the factory inspection, if it is detected that the refrigerator is connected to the power supply, the control automatically starts the factory inspection program.

[0051] Specifically, in the embodiment of the present invention, when the refrigerator is shipped out of the factory, a test is performed, and if the test finds that the refrigerator has been connected to a power source, the system automatically starts a set of preset test programs. This set of programs is intended to check whether the various functions of the refrigerator are normal, so as to ensure that the refrigerator can work normally when it is delivered to the user.

[0052] Among them, the power connection detection is to confirm whether the refrigerator is connected to the power supply. Once the power supply is confirmed, the system will automatically start the detection program without manual intervention.

[0053] Then perform the test. Specifically, the test procedure may include temperature testing, compressor operation, refrigeration effect, and functional testing of various indicator lights and buttons.

[0054] The present invention automatically starts the detection procedure, can improve production efficiency, reduce human errors, and ensure that the product is in the best condition before delivery.

[0055] Step S200, identifying the refrigerator model of the refrigerator to be tested, controlling to start the testing program corresponding to the refrigerator model; testing whether each sensor inside the refrigerator is started normally;

[0056] Before this step is implemented, it is necessary to set up a test program corresponding to the refrigerator model in advance. During the production process, each model of refrigerator will be equipped with a specific set of test programs. These test programs are designed to conduct appropriate checks on the functions and characteristics of each model. Specifically: the test program must first correspond to the refrigerator model. Different models of refrigerators may differ in design, function and technical parameters, so special test programs need to be designed for their respective characteristics.

[0057] In the embodiment of the present invention, before the refrigerator is produced or inspected, these detection programs are pre-programmed and stored in the control system of the refrigerator to ensure that they can be immediately called when needed.

[0058] Each testing procedure will include test items unique to the model, such as temperature control system, cooling effect, noise level, energy consumption index, door seal and other functions.

[0059] The present invention adopts automated detection, which makes the detection process automatic, reduces the need for human intervention, and improves the efficiency and consistency of detection.

[0060] Through the preset detection procedure, the present invention can ensure that each model of refrigerator is strictly inspected before leaving the factory to ensure that the quality and performance meet the standards.

[0061] In this step S200, when the refrigerator model of the refrigerator to be detected is identified, the control starts the detection program corresponding to the refrigerator model; and detects whether each sensor inside the refrigerator is started normally.

[0062] When this step is specifically implemented, the refrigerator model of the refrigerator to be tested is identified. The refrigerator model usually represents a certain specific design, function and technical parameters. Different models of refrigerators may have differences in refrigeration methods, energy consumption standards, internal structures and control systems.

[0063] When the present invention identifies the refrigerator model, the specific model can be confirmed by reading the model label, barcode or RFID tag inside the refrigerator. This information will be used for subsequent program selection.

[0064] In the present invention, once the model of the refrigerator is identified, the system will search for the test program associated with the model. This is pre-set to ensure that each model can enter the corresponding test process. After starting the test program, the system will gradually check the various functions in the refrigerator according to the program requirements.

[0065] Check whether the sensors inside the refrigerator are started normally. The refrigerator is equipped with multiple sensors, such as ambient temperature sensors, refrigeration sensors, variable temperature sensors, freezing sensors, freezing and defrosting sensors, etc. These sensors are crucial to the normal operation of the refrigerator.

[0066] During the detection process, the present invention monitors the response of each sensor of the refrigerator to confirm whether it can be started correctly and feedback data in time. If a sensor fails to work properly, the problem will be recorded for subsequent maintenance or adjustment.

[0067] It can be seen that this step S200 is intended to ensure that each refrigerator can undergo the most suitable functional test according to its model before leaving the factory, and verify the working status of key sensors to ensure the performance and safety of the refrigerator.

[0068] Step S300: When it is detected that all sensors inside the refrigerator are started normally, the control automatically enters the rapid detection program to perform all load detection within the first predetermined time;

[0069] In the embodiment of this step, in the previous step, it is detected that the sensors inside the refrigerator (such as the ambient temperature sensor, the refrigeration sensor, the temperature change sensor, the freezing sensor, the freezing and defrosting sensor, etc. are all normal) are started normally. This is the basis for ensuring that the refrigerator can accurately monitor and adjust the internal environment.

[0070] If all sensors are functioning properly, the control automatically enters the quick test procedure.

[0071] In the embodiment of the present invention, once the sensor is confirmed to be normal, a preset quick detection program will be automatically started. This program is intended to efficiently complete all necessary load detections.

[0072] A quick test program can be set up to include multiple steps, such as cooling effect testing, noise level monitoring, energy consumption testing, etc., all of which will be completed within a set time.

[0073] When the present invention is implemented, it will automatically control all load tests within a first predetermined time (e.g., 1 minute). The time of the rapid test in the present invention is accurately set to ensure that the test process is efficient and does not waste resources. Preferably, the present invention is set to complete all load tests within 1 minute.

[0074] During this 1 minute, the present invention will evaluate the performance of the refrigerator under different loads to ensure that it can operate normally under various usage conditions.

[0075] For example, when a refrigerator model is "AX", during the detection process, the system first confirms that its temperature sensor, door switch sensor and fan sensor are working properly. Then, the system automatically enters the quick detection program: for example, the refrigeration effect test: within the set time, the refrigerator is cooled from room temperature to the set refrigeration temperature (such as 4°C), and the cooling speed is monitored.

[0076] Energy consumption test: Records energy consumption during a quick test to ensure it complies with energy efficiency standards.

[0077] Noise test: Monitor the noise level of the refrigerator at various stages of operation to ensure it is within acceptable range.

[0078] In this way, the automated rapid testing procedure of the present invention can complete multiple tests in a relatively short time, significantly improving the efficiency of the production line and reducing the need for manual intervention. Moreover, through comprehensive testing of all loads, potential problems can be discovered in a timely manner, ensuring that each refrigerator meets quality standards when leaving the factory, thereby enhancing consumer trust.

[0079] Step S400: When all loads are detected to be fault-free, a system cooling test is performed within a second predetermined time to control and detect the temperature of each sensor inside the refrigerator;

[0080] In this step embodiment, in the refrigerator detection process, when all load detections are completed and no faults are found, the system will enter the next stage - system cooling detection. The main purpose of this step is to evaluate the cooling capacity of the refrigerator under actual working conditions and to ensure that the temperature control of each internal sensor is normal.

[0081] The start of the system cooling detection is usually carried out within the second predetermined time. In the embodiment of the present invention, the second predetermined time length is preferably set to 24 minutes, which of course depends on the design and requirements of the refrigerator.

[0082] In the embodiment of the present invention, during this time period (i.e., within 1-24 minutes), the temperature changes inside the refrigerator are continuously monitored to ensure that it can operate stably within the set cooling range.

[0083] And control the temperature of each sensor. Specifically, during the cooling detection process, the embodiment of the present invention will monitor multiple temperature sensors inside the refrigerator in real time. These sensors may include temperature sensors for the refrigerator compartment and the freezer compartment to ensure that the temperature in different areas of the refrigerator is uniform and meets the set standards.

[0084] The present invention records the readings of each sensor and compares them with the preset temperature range. If the temperature of any sensor is found to be out of the normal range, the system will immediately sound an alarm and record the fault information.

[0085] In the embodiment of the present invention, after the cooling test is completed, the system will analyze the collected data to evaluate the overall cooling performance of the refrigerator. This includes key indicators such as cooling efficiency and temperature fluctuation range. If all indicators are within the normal range, a test report will be generated to confirm that the refrigerator's cooling system is operating well.

[0086] For example, assuming that a refrigerator model is "XXXX Y", after completing all load detections, the system enters the cooling detection phase:

[0087] 1) Start the cooling test. The system is set to perform the cooling test within 24 minutes. The refrigerator starts running and the internal temperature drops from room temperature (about 25°C) to the set refrigeration temperature (4°C).

[0088] 2) Sensor monitoring: During this process, the temperature sensors in the refrigerator and freezer continuously record temperature changes. Assume that the sensor in the refrigerator stabilizes at 4°C within 10 minutes, while the sensor in the freezer drops to -18°C within 15 minutes.

[0089] 3) Data recording and analysis. Specifically, after the test, the performance of each sensor can be analyzed. It is found that the temperature fluctuation of the refrigerator is within ±1°C, and the fluctuation of the freezer is within ±2°C, both of which meet the preset standards.

[0090] It can be seen that the embodiments of the present invention can confirm the cooling capacity of the refrigerator under actual use conditions through system cooling detection, ensuring that it can effectively maintain the freshness of food. By monitoring the temperature of each sensor, potential problems can be discovered in time, reducing the risk of failure in subsequent use and improving the overall reliability of the product. It can also ensure that the refrigerator maintains a stable temperature during operation, which helps to improve user satisfaction and reduce food spoilage caused by unstable temperature.

[0091] Step S500: When the difference between the ambient temperature and the temperature of each sensor inside the refrigerator is detected to be within a preset temperature difference range, the refrigerator to be tested is determined to be qualified; otherwise, the refrigerator to be tested is determined to be unqualified.

[0092] In this step embodiment, when the refrigerator cooling test is performed, the temperature of each sensor inside the refrigerator will be monitored in real time and compared with the ambient temperature. The specific steps are as follows:

[0093] After the above steps, temperature data will be collected in real time from temperature sensors at multiple locations inside the refrigerator (such as the refrigerator and freezer), and the temperature information of the external environment (such as room temperature) will be recorded at the same time.

[0094] Then, calculate the temperature difference, and calculate the difference between the reading of each sensor and the ambient temperature. The formula is: temperature difference = sensor temperature - ambient temperature difference.

[0095] Then, the preset temperature difference range is compared with the preset temperature difference range set by the system in the present invention, which takes into account the design standard and actual use conditions of the refrigerator. For example, the preset temperature difference range may be ±2°C. If the calculated temperature difference is within this range, the performance of the sensor is determined to be qualified; if it is out of the range, it is determined to be unqualified.

[0096] For example, when the ambient temperature of the refrigerator is 25°C, the sensor in the refrigerator compartment records a temperature of 23°C and the sensor in the freezer compartment records a temperature of 20°C.

[0097] Then the temperature difference of the refrigerated room is calculated as: temperature difference = 25°C - 23°C = 2°C;

[0098] The calculation of the temperature difference of the freezing room is: temperature difference = 25°C - 20°C = 5°C;

[0099] Assuming the preset refrigeration temperature difference is ≥10℃ and the freezing temperature difference is ≥20℃:

[0100] If the refrigerated room temperature difference (2°C) does not meet the condition of ≥10°C, it is judged as unqualified;

[0101] "The temperature difference of the freezing room (5℃) does not meet the condition of ≥20℃ and is judged as unqualified.

[0102] For another example: when the ambient temperature of the refrigerator is 25°C, the sensor in the refrigerator compartment records a temperature of 3°C, and the sensor in the freezer compartment records a temperature of -20°C.

[0103] Then the refrigerated room temperature difference is calculated as: temperature difference = 25°C - 3°C = 22°C;

[0104] The calculation of the temperature difference of the freezing room is: temperature difference = 25°C + 20°C = 45°C;

[0105] Assume that the preset refrigeration temperature difference is ≥10℃:

[0106] The refrigerated room temperature difference (22°C) meets the condition of ≥10°C and is considered qualified;

[0107] "The temperature difference of the freezing room (45℃) meets the condition of ≥20℃ and is judged as qualified.

[0108] It can be seen that in the embodiment of the present invention, by monitoring the difference between the ambient temperature and the internal sensor temperature, it can be ensured that the refrigerator effectively completes the cooling task and ensures the freshness of the food. In addition, temperature anomalies can be discovered in advance, which can avoid more serious failures in the future and reduce the cost of repairs and replacement parts. In addition, the present invention ensures that the refrigerator undergoes comprehensive performance verification before leaving the factory through strict temperature difference inspection, which can improve product quality and increase customer trust and satisfaction.

[0109] In a further embodiment, Figure 2As shown, the refrigerator factory inspection method according to the embodiment of the present invention further includes the steps of:

[0110] Step S600, when the factory inspection time exceeds the second predetermined time, the control exits the factory inspection and automatically returns to the energy-saving state; when the refrigerator is in the energy-saving state, the control automatically matches different set values ​​for the refrigerator refrigerator compartment, temperature-changing room, and freezer compartment according to different ambient temperatures.

[0111] In this step embodiment, during the factory inspection of the refrigerator, if the inspection time exceeds the predetermined second time limit, for example, more than 24 minutes (the inspection is basically completed according to the quick search procedure of the present invention), the present invention will automatically exit the inspection mode and return to the energy-saving state. The purpose of this mechanism is to prevent the increase of energy consumption caused by too long inspection time, and at the same time ensure that the refrigerator can operate efficiently after the inspection.

[0112] Specifically, the system of the present invention monitors the time of factory inspection in real time. If the inspection time exceeds a set second time threshold (eg, 24 minutes), the present invention controls the exit inspection.

[0113] That is, in the embodiment of the present invention, once the detection time exceeds the threshold, the system will automatically exit the current factory detection mode and enter the energy-saving state. In this state, the refrigerator will reduce energy consumption and reduce unnecessary power consumption.

[0114] In the energy-saving state, the refrigerator of the embodiment of the present invention will automatically adjust the temperature setting values ​​of the refrigerating chamber, the temperature-changing chamber and the freezing chamber according to the changes in the ambient temperature. For example, when the ambient temperature is high, the temperature setting value of the refrigerating chamber may be lower to ensure that the food remains fresh; and when the ambient temperature is low, the setting value of the freezing chamber may be adjusted upward accordingly to save energy.

[0115] Thus, the embodiment of the present invention can significantly reduce the energy consumption of the refrigerator during the factory inspection by automatically switching to the energy-saving state, thereby reducing electricity expenses and environmental burdens. In addition, by reasonably controlling the inspection time, the efficiency of the inspection process is ensured and resource waste is avoided.

[0116] That is, in the embodiment of the present invention, preferably, the first predetermined time is 1 minute, and the second predetermined time is 24 minutes.

[0117] In a further embodiment, Figure 2 As shown, the refrigerator factory inspection method further includes the steps of:

[0118] Step S700: When the factory inspection time exceeds the second predetermined time, the control does not execute the inspection procedure at the next power-on, and directly starts the refrigeration.

[0119] In the embodiment of the present invention, when the factory inspection time exceeds the second predetermined time (for example, more than 24 minutes), that is, in the embodiment of the present invention, when the inspection time during the factory inspection exceeds the second predetermined time, that is, more than 24 minutes and the inspection is qualified, the user purchases it home and does not repeat the inspection program after powering on, but directly starts the refrigeration program for refrigeration, which can effectively shorten the startup refrigeration time and provide convenience for the user.

[0120] That is, in the embodiment of the present invention, after normal inspection in the factory (more than 24 minutes) and passing the inspection, the user buys the product home, turns on the power, and uses it for normal refrigeration. The rapid inspection program will not be entered again, and the situation of refrigeration or temperature change without refrigeration in the first few minutes will not occur, thereby improving the user experience.

[0121] In a further embodiment, Figure 2 As shown, the refrigerator factory inspection method further includes the steps of:

[0122] Step S800, when the factory inspection time exceeds the second predetermined time and the inspection program needs to be executed next time the power is turned on, the control restores the factory settings through the combination button. After the factory settings are restored, the power is turned on again to start, and the refrigerator does not need to return to temperature, and it automatically enters the quick inspection program directly.

[0123] That is, in the embodiment of the present invention, even if the factory inspection time of the refrigerator exceeds 24 minutes, if you want to enter the quick inspection program again, you can also operate the special combination key to restore the factory setting state. You can still enter the quick inspection program when the power is turned on again. There is no need to wait for the refrigerator to return to temperature, and it does not take up space. The inspection is very flexible and convenient.

[0124] Furthermore, the method described in the embodiment of the present invention also includes:

[0125] When a sensor in the refrigerator is detected to be faulty and cannot automatically enter the quick detection program, the specific sensor fault is displayed through the designated query button command.

[0126] That is, in the embodiment of the present invention, if a sensor fault is detected and the quick detection program cannot be entered, the specific sensor fault can be found out and repaired through a specific query button.

[0127] Based on the above embodiment, the present invention further describes in detail a refrigerator factory inspection method of the present invention through a specific application embodiment:

[0128] A refrigerator factory inspection method of this specific application embodiment includes the following steps:

[0129] During the factory inspection, the refrigerator model of the refrigerator to be inspected is identified, and the mainboard and the inspection program corresponding to the refrigerator model are determined; the refrigerator to be inspected is powered on to execute the inspection program, and the power of each small load is inspected one by one within the first time, such as 1 minute. Figure 3As shown, after the detection is completed, the sensor is placed in the refrigerator to detect the temperature of the internal sensor; if the difference between the ambient temperature and the temperature of the internal sensor is within the preset temperature difference range, the refrigerator to be detected is qualified, otherwise, the refrigerator to be detected is unqualified.

[0130] Specifically, when the power is turned on, all sensors (such as ambient temperature sensor, refrigeration sensor, variable temperature sensor, freezing sensor, and defrosting sensor) are checked to be fault-free, and the system automatically enters the quick test program, performs all load tests within 1 minute, and performs system cooling tests within 1 minute to 24 minutes. Figure 4 When the quick test program runs for more than 24 minutes, the quick test program will be exited and the energy-saving state will be automatically restored. Energy-saving state: According to different ambient temperatures, the refrigerator's refrigerator compartment, variable temperature compartment, and freezer compartment automatically match different set values, which can meet user requirements and save energy.

[0131] If the sensor is faulty and the quick detection program cannot be entered, you can use a specific query button to find out the specific sensor fault and then repair it.

[0132] In this specific embodiment, the load detection within 1 minute is as follows: Figure 3 As shown, the dynamic detection process includes 1, 2, 3, 4...11. The retrieval duration is 0-60 seconds (S). The detected loads include cold building fans, condensing fans, double damper actions, defrosting heaters, flap heaters, etc. The sequential switches of the loads are detected, where on represents on and off represents off. For example, the refrigeration fan stops for 3S, turns on for 4S, stops for 3S, and then the next condensing fan turns on for 4S and stops for 3S.

[0133] Then, the refrigeration system cooling test is carried out within 1-24 minutes. The specific test is as follows: Figure 4 As shown, the temperatures of the freezing room, the refrigerating room and the temperature-changing room are detected respectively.

[0134] In the embodiment of the present invention, during the in-factory inspection, the power can be turned on to enter the quick inspection program without any button operation, thereby reducing labor costs and improving production efficiency. Through the program, the in-factory inspection time is not more than 24 minutes and the line is offline, and the quick inspection program can still be entered after the power is turned on next time. Even if the in-factory inspection time exceeds 24 minutes, if you want to enter the quick inspection program again, you can also operate a special combination key to restore the factory setting state, and you can still enter the quick inspection program after the power is turned on again. There is no need to wait for the refrigerator to return to temperature, and no space is occupied.

[0135] After the normal inspection in the factory (more than 24 minutes), the user can turn on the power of the refrigerator purchased at home and use it for normal cooling. The refrigerator of the present invention will not enter the rapid inspection program again, and the situation of refrigeration or temperature change without cooling in the first few minutes will not occur, thereby improving the user experience.

[0136] As can be seen from the above, the present invention achieves the purpose of high-efficiency detection in the factory and improving user experience outside the factory through improvements.
