[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0022] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] As living standards continue to improve, people's demands for new functions of home appliances continue to emerge, the iteration cycle of home appliance products is getting shorter and shorter, and higher requirements are being placed on testing.

[0024] Related home appliance tests can only display test data in real time, without data recording and transmission functions. Changes in test data during the test process are not effectively recorded, and test data needs to be manually exported for analysis. Data processing is relatively cumbersome, and the test process is not effectively detected in real time. Program errors such as the device issuing instructions but not executing them or executing instructions without issuing them are not monitored.

[0025] Based on this, the present application proposes using a first data acquisition device to receive first test data collected by the home appliance during the test process of the home appliance; and using a second data acquisition device to collect second test data of the home appliance during the test process, thereby increasing the diversity and completeness of the collected test data and compensating for the lack of test data types. Then, a server is used to compare the data of the same type in the first test data and the second test data, and an abnormality prompt is issued when an abnormality is found in the comparison; and the remaining test data in the first test data and the second test data are judged as non-routine faults and conventional faults respectively, and a fault prompt is issued when a fault is judged to have occurred. Among them, non-routine faults refer to faults that occur but do not reach the point of triggering the built-in fault alarm in the home appliance and faults that the home appliance itself cannot detect. Conventional faults refer to faults that occur and reach the point of triggering the built-in fault alarm in the home appliance. The first test data and the second test data can be used quickly and effectively to detect, monitor and warn the product performance and process of the home appliance, and detect abnormalities in advance, thereby improving test efficiency and fault detection rate. For details, please refer to the technical solution of any of the following embodiments.

[0026] See Figure 1 , Figure 1 FIG1 is a schematic diagram of the structure of the first embodiment of the home appliance testing system provided by the present application. The testing system includes: a first data acquisition device 20 , a second data acquisition device 30 and a server 40 .

[0027] The first data acquisition device 20 is provided on the home appliance 10 and is configured to receive first test data collected by the home appliance 10 during the testing process. In some embodiments, the first data acquisition device 20 is an Internet of Things device, such as a Wi-Fi module. The home appliance 10 can be at least one of a variety of home appliances, such as an air conditioner, a washing machine, a refrigerator, a television, a dishwasher, a microwave oven, and a range hood.

[0028] In some embodiments, the first test data collected by the home appliance 10 refers to data that can be obtained by the home appliance 10 itself, such as program-related instructions during the test process, data and instructions exchanged between functional components, and sensor data collected by built-in sensors, such as temperature collected by a thermistor.

[0029] It is understood that the built-in program of the home appliance 10 inherently includes corresponding fault detection logic. Based on this, the fault detection logic involved in the built-in program of the home appliance 10 can be defined as a routine fault. Furthermore, the program actually used during the testing of the home appliance 10 is also the built-in program of the home appliance 10, eliminating the need to develop a separate test program.

[0030] The second data acquisition device 30 is installed on the home appliance 10 and is used to collect second test data from the home appliance 10 during the test process. The first and second test data may have at least some of the same data type. For example, while the first test data may collect temperature using a built-in thermistor, the second data acquisition device 30 may also collect temperature using an external temperature acquisition device, thereby verifying whether any abnormalities occur during the temperature acquisition process. In some embodiments, the second data acquisition device 30 includes different types of external data acquisition devices, each corresponding to a corresponding type of functional component on the home appliance 10. For example, the external data acquisition device may include at least one of a voltage acquisition device, a current acquisition device, a temperature acquisition device, a humidity acquisition device, a speed acquisition device, and a flow rate acquisition device. The voltage acquisition device may acquire the voltage corresponding to a corresponding electrical component in the home appliance 10. The current acquisition device may acquire the current corresponding to a corresponding electrical component in the home appliance 10. The temperature acquisition device may acquire the temperature corresponding to a corresponding electrical component in the home appliance 10, such as the temperature of a heating element. The humidity acquisition device may acquire the humidity corresponding to a corresponding electrical component in the home appliance 10. The speed acquisition device can collect the speed of corresponding electrical components in the household appliance 10, such as motor speed. The flow rate acquisition device can collect the flow rate of corresponding electrical components in the household appliance 10, such as water flow. The second data acquisition device 30 can also include corresponding acquisition devices such as a power meter, flow meter, current transformer, and switch acquisition card to collect corresponding data.

[0031] The server 40 is communicatively connected to the first data acquisition device 20 and the second data acquisition device 30, respectively, and is configured to compare data of the same type in the first test data and the second test data, and to provide an exception notification if an abnormality is found in the comparison. For example, if the first test data and the second test data have temperatures, the first temperature in the first test data and the second temperature in the second test data are compared. If the difference between the first temperature and the second temperature exceeds a threshold, it indicates that the temperature acquisition is abnormal. If the difference between the first temperature and the second temperature does not exceed the threshold, it indicates that the temperature acquisition is normal. If an abnormality is found in the comparison, an exception notification is provided.

[0032] The server 40 judges the remaining test data in the first test data and the second test data as unconventional faults and conventional faults respectively, and issues a fault prompt when a fault is determined to have occurred. An unconventional fault refers to a fault that has occurred but has not reached the point of triggering the built-in fault alarm in the home appliance 10 and a fault that the home appliance 10 itself cannot detect. A conventional fault refers to a fault that has occurred and has reached the point of triggering the built-in fault alarm in the home appliance 10.

[0033] In some embodiments, the server 40 analyzes and processes the first test data according to the relevant communication protocol of the first data acquisition device 20, and determines whether the preset steps and instructions involved meet the program requirements. If not, a red alarm prompt is displayed on the monitoring interface and the user is informed of the device abnormality information by email or other means, and the abnormal information is stored for the user to trace back. For example: the first step of the program preset is 01 drainage for 30 seconds, but the instruction for 01 drainage is not obtained. At this time, an alarm prompt is displayed on the monitoring interface to the user, and it is simultaneously determined whether the program has ended. If it has not ended, it continues to the next step 02 water intake 0.3L, and the cycle continues until the program ends. Among them, 01 and 02 represent the order of steps during the program operation. For example, 01 represents the first step, 01 drainage for 30 seconds means that it is in the first step, drainage for 30 seconds. 02 represents the second step, 02 water intake 0.3L means that 0.3L of water needs to be added in the second step.

[0034] The server 40 compares the second test data, such as comparing the corresponding data in the second test data with the preset value / instruction / status number. If it is not within the threshold range, a red alarm prompt is displayed on the monitoring interface, and the user is notified of the device abnormality information by email or other means. The information is stored for easy user tracing. For example, after the program starts, the first test data obtains the preset 01 drain 30s and the instruction is normal. At this time, the actual action obtained by the second test data is compared with the preset value of draining, or the actual action is water filling, or not running, or draining for 20s. If it does not match the preset value of draining, the monitoring interface displays an abnormality prompt and determines whether the program has ended. If it has not ended, the program will continue to run in this loop until the program ends.

[0035] The server 40 compares and calculates the first test data and the second test data with the data in the test data. If there is an abnormality, an orange reminder will be displayed on the monitoring interface and the user will be informed of the abnormal information of the device by email or other means. The abnormal information is stored for the user to trace back. This process can identify hidden problems of the home appliance 10. For example: abnormal thermistor detection, inner tank temperature <0°C, or inner tank temperature >90°C; abnormal heating, etc. It also determines whether the program on the home appliance 10 has ended, and saves and records the relevant abnormal data to facilitate the user to analyze and trace the abnormality later. If the user threshold is reached, the data is saved and the loop is entered.

[0036] The alarm indication here refers to devices marked with a red background color on the display terminal indicating that the device has reached an alarm state, and devices marked with an orange background color indicating that the device has not reached an alarm state but has an abnormality. Data records can be exported, including but not limited to the second test data collected by the second data acquisition device 30, the first test data collected by the first data acquisition device 20, preset values, time, various load states, grid power supply status, etc. Users can quickly understand and trace the operating status of the home appliance 10 on the display terminal, preventing users from being unable to promptly discover and record abnormalities during the test process while not on site.

[0037] In some embodiments, the household appliance 10 may be a dishwasher. The non-routine faults corresponding to the dishwasher may include at least one of the following: abnormal thermistor detection, abnormal flow rate, abnormal heating, abnormal power, abnormal fan, abnormal networking, abnormal countdown, and abnormal regeneration. The corresponding judgment conditions for these non-routine faults may be set in the aforementioned non-routine fault warning function database.

[0038] In some embodiments, the abnormal fault may also include a power abnormality, wherein the power abnormality condition is: during the operation phase of the dishwasher, the power of the dishwasher is greater than 2400W or the power of the dishwasher is greater than 2150W*test voltage.

[0039] In some embodiments, when the home appliance 10 is a dishwasher, the server 40 performs both non-routine and regular fault determinations on the test data related to thermistor, flow rate, power, fan, networking, countdown, and regeneration in the first and second test data collected from the home appliance 10, and issues a fault prompt when a fault is determined to have occurred. A non-routine fault refers to a fault that has occurred but has not reached a level that triggers a regular fault alarm, while a regular fault refers to a fault that has occurred and reached a level that triggers a regular fault alarm. That is, if the data in the first and second test data meets the determination criteria for thermistor detection abnormality, flow rate abnormality, heating abnormality, power abnormality, fan abnormality, networking abnormality, countdown abnormality, or regeneration abnormality, the corresponding abnormality can be determined to have occurred.

[0040] In some embodiments, the thermistor detection abnormality includes: a first type of thermistor detection abnormality and a second type of thermistor detection abnormality.

[0041] The first type of thermistor detection anomaly is considered to occur when the dishwasher's power is greater than a first preset power and the temperature of the dishwasher's inner tank remains below a preset value within a preset time period. For example, if the dishwasher's power is greater than 1000W and the temperature of the dishwasher's inner tank does not increase by 1°C within 5 minutes, the first type of thermistor detection anomaly is considered to have occurred.

[0042] The second type of thermistor detection abnormality is determined when the dishwasher's internal temperature is less than the first preset temperature or greater than the second preset temperature, or when the first preset temperature is less than the second preset temperature. For example, if the internal temperature is less than 0°C or greater than 90°C, the second type of thermistor detection abnormality is considered to have occurred.

[0043] Traffic anomalies include: the first type of traffic anomaly and the second type of traffic anomaly.

[0044] The first type of flow abnormality occurs when the dishwasher is not in the water filling phase and the flow meter pulse is detected. For example, if the dishwasher is in the water filling phase (rinsing, main wash, draining) and the flow meter pulse is detected, the first type of flow abnormality can be determined.

[0045] The second type of flow anomaly is identified when the dishwasher is filling with water and the accumulated pulse is greater than the first preset pulse or less than the second preset pulse; the first preset pulse is greater than the second preset pulse. For example, if the dishwasher is filling with water and the accumulated pulse is greater than the target pulse * 1.05 or the accumulated pulse is less than the target pulse * 0.95, then the second type of flow anomaly is identified.

[0046] The heating abnormality includes the first heating abnormality, the second heating abnormality and the third heating abnormality.

[0047] The first type of heating anomaly occurs when the dishwasher is in the main wash or rinse cycle and the power cannot be reduced to the second preset power within the first preset time. For example, if the dishwasher is in the main wash or rinse cycle and the power is >1000W and then reduced to <100W, the timer starts, and the power remains >1000W within 10 minutes, then the first type of heating anomaly is considered to have occurred.

[0048] The second type of heating anomaly occurs when the dishwasher is in the main wash or rinse cycle and the water-out protection is triggered. For example, if the dishwasher is in the main wash or rinse cycle and the water-out protection is triggered, this can be considered a second type of heating anomaly.

[0049] The third type of heating anomaly is identified when the thermistor temperature falls below a third preset temperature and the dishwasher's power is below a third preset power for a second preset duration during the main wash or rinse cycle. For example, if the thermistor temperature is below 30°C and the dishwasher's power is below 1000W for 10 minutes during the main wash or rinse cycle, the third type of heating anomaly is considered to have occurred.

[0050] Fan abnormalities include the first type of fan abnormalities and the second type of fan abnormalities.

[0051] The first type of fan abnormality is identified when the dishwasher's power consumption is less than a fourth preset power consumption for a third preset duration during the drying phase. For example, if the dishwasher's power consumption is less than 10W for 10 minutes during the drying phase, this is considered a type 1 fan abnormality.

[0052] The second type of fan abnormality is identified when the dishwasher's power consumption is less than a fourth preset power level for a fourth preset duration while the dishwasher is in storage; this fourth preset duration is greater than the third preset duration. For example, if the dishwasher's power consumption is less than 10W for two hours during storage, this is considered a second type of fan abnormality.

[0053] Network anomalies include the first and second types of network anomalies. The first type of network anomaly is defined as a single network anomaly feedback period lasting for the fifth preset duration. For example, if the network anomaly feedback period lasts for 30 minutes, it is considered a first type of network anomaly.

[0054] The second type of network anomaly is identified when the number of network anomaly feedback exceeds the preset number within the sixth preset time period. For example, if the number of network anomaly feedback exceeds three within one hour, the second type of network anomaly is considered to have occurred.

[0055] Countdown anomalies include the first type of countdown anomaly and the second type of countdown anomaly.

[0056] The first countdown anomaly condition is: the countdown increases. That is, normally the countdown gradually decreases, but the collected test data shows that the current countdown is greater than the previous countdown in the timing sequence, then the first countdown anomaly occurs.

[0057] The second type of countdown anomaly occurs when the countdown decreases in a way that doesn't conform to the standard time unit decrease logic. For example, if the countdown decreases by more than 5 minutes at a time. Countdowns typically decrease gradually, for example, using seconds or minutes as the unit of time. If the difference between the current countdown and the previous countdown is greater than the unit time, a second countdown anomaly occurs. For example, if the current countdown is 4 minutes and the previous countdown was 10 minutes, and the difference exceeds one minute, a second countdown anomaly is considered.

[0058] Conditions for abnormal regeneration include: a mismatch between the regeneration position and the corresponding number of regenerations, and a greater amount of water in the cumulative regeneration period than the non-regeneration water volume. For example, if the regeneration position and the corresponding number of regenerations do not match, and the cumulative regeneration period water volume shows an excess of 1L compared to the non-regeneration water volume, a regeneration abnormality can be considered. The regeneration function of a dishwasher is primarily used for water softener maintenance. By adding softening salt, the resin's adsorption capacity is restored, thereby continuously reducing water hardness. If softening salt has not been used for an extended period, regeneration is required to restore device performance.

[0059] In some embodiments, when an unusual fault occurs in the home appliance 10, a fault prompt may be displayed on the corresponding display terminal, for example, in orange, without interrupting the testing of the home appliance 10. After performing maintenance on the home appliance 10, a clear fault button may be clicked, and the display terminal may switch the color displayed from orange to blue.

[0060] In some embodiments, a common failure of a dishwasher is described as follows:

[0061] For abnormal water inflow, the judgment conditions are as follows: if 30 pulses are not detected within 60 seconds during the water inflow step, the system will enter fault processing; if the water inflow in other states other than the water inflow stage exceeds 2 liters, the system will enter fault processing, and 2 liters of abnormal water inflow will be accumulated again after each water inflow step.

[0062] For heating abnormalities, the judgment conditions are as follows: during the entire washing sequence, there is no abnormality in the variable frequency motor, all washing heating steps have not reached the set temperature, and the washing heating steps that are judged to rise by 3°C have never detected a temperature increase of more than 3°C, and the thermistor has no faults. Washing is completed and fault processing begins.

[0063] For thermistor faults, the judgment condition is: if the thermistor circuit is open / short-circuited during the online inspection process, the fault processing is started.

[0064] That is, a conventional fault of the dishwasher may refer to a fault corresponding to a built-in fault alarm in the dishwasher.

[0065] In this embodiment, during the testing process of the home appliance 10, the first data acquisition device 20 is used to receive first test data collected by the home appliance 10; and the second data acquisition device 30 is used to collect second test data of the home appliance 10 during the testing process, thereby increasing the diversity and completeness of the collected test data and compensating for the lack of test data types. Then, the server 40 compares the data of the same type in the first test data and the second test data, and issues an abnormality prompt when an abnormality is found in the comparison; and the remaining test data in the first test data and the second test data are respectively judged for non-routine faults and conventional faults, and a fault prompt is issued when a fault is determined to have occurred. Among them, non-routine faults refer to faults that occur but do not reach the level of triggering the built-in fault alarm of the home appliance 10 and faults that the home appliance 10 cannot detect itself. Conventional faults refer to faults that occur and reach the level of triggering the built-in fault alarm of the home appliance 10. The first test data and the second test data can be quickly and effectively used to detect, monitor and warn the product performance and process of the home appliance 10, and abnormalities can be discovered in advance, thereby improving testing efficiency and fault detection rate.

[0066] That is, the first and second test data can complement each other in data collection. For example, in the case of a program error, such as a device issuing a command but not executing it, or executing a command without issuing it, the first test data collected by the home appliance 10 cannot reflect whether the hardware executed the command, while the second test data alone cannot determine whether the command was fully executed or whether an action other than the command was executed. Based on this, the first and second test data can complement each other in data collection, enabling early warning detection of anomalies that are present but have not yet reached an alarm state, thereby improving the accuracy of subsequent fault detection.

[0067] See Figure 2 , Figure 2 1 is a schematic diagram of the structure of the second embodiment of the home appliance testing system provided by the present application. The testing system includes: a first data acquisition device 20, a second data acquisition device 30, a server 40 and a display terminal 50.

[0068] The relationship between the first data acquisition device 20, the second data acquisition device 30 and the server 40 can be found in other embodiments of the present application and will not be described in detail here.

[0069] The display terminal 50 is in communication with the server 40 and is used to display unusual faults and regular faults, distinguishing them by different colors. The server 40 compares and calculates the first test data and the second test data with the data in the unusual fault warning function database. If there is an abnormality, an orange reminder will be given on the display terminal 50 and the user will be informed of the abnormal information of the home appliance 10 by email or other means. The information is stored for easy tracing by the user. In this way, hidden problems of the home appliance 10 can be identified. For example, when the inner tank temperature is <0°C or the inner tank temperature is >90°C, the thermistor detection is considered abnormal. During the main wash and rinse stages of the dishwasher, if the dishwasher power is >1000W and the power is reduced to <100W, the timing starts. If the dishwasher power is >1000W within 10 minutes, the heating is considered abnormal.

[0070] That is, the server 40 is also used to store the corresponding first test data and second test data when an abnormality or failure occurs, so as to facilitate tracing by the user.

[0071] See Figure 3 , Figure 3 1 is a flow chart of a first embodiment of a method for testing household appliances provided by the present application. Applied to the above-mentioned server 40, the testing method includes:

[0072] Step 31: Receive first test data sent by a first data acquisition device, and receive second test data sent by a second data acquisition device.

[0073] The first test data is collected by the home appliance itself and sent to the first data collection device 20 .

[0074] The second test data is collected by arranging a second data collection device on the household appliance.

[0075] Step 32: Compare the data of the same type in the first test data and the second test data, and issue an abnormality prompt if an abnormality is found in the comparison.

[0076] Step 33: Performing non-routine fault and conventional fault judgment on the remaining test data in the first test data and the second test data respectively, and giving a fault prompt when a fault is judged to have occurred.

[0077] Among them, non-routine faults refer to faults that occur but do not reach the point of triggering the built-in fault alarm in the home appliance and faults that the home appliance itself cannot detect. Routine faults refer to faults that occur and reach the point of triggering the built-in fault alarm in the home appliance.

[0078] The specific processes from step 31 to step 33 can be referred to other embodiments simultaneously and will not be described in detail here.

[0079] In one application scenario, the first data acquisition device is an IoT device, and the second data acquisition device includes different types of external data acquisition devices, each of which corresponds to a corresponding type of functional device on a household appliance. The external data acquisition devices include at least one of a voltage acquisition device, a current acquisition device, a temperature acquisition device, a humidity acquisition device, a speed acquisition device, and a flow acquisition device.

[0080] Household appliances include dishwashers, and unconventional faults include at least one of the following: abnormal thermistor detection, abnormal flow, abnormal heating, abnormal power, abnormal fan, abnormal networking, abnormal countdown, and abnormal regeneration.

[0081] After receiving the first and second test data, the server uses the corresponding data to perform corresponding anomaly detection. The server uses the dishwasher's power and inner tank temperature to determine if the thermistor is abnormal. A first type of thermistor detection anomaly is determined when the dishwasher's power is greater than a first preset power and the change in the dishwasher's inner tank temperature within a preset time period is less than a preset value.

[0082] When the temperature of the inner tank of the dishwasher is lower than the first preset temperature or higher than the second preset temperature; and the first preset temperature is lower than the second preset temperature, it is determined that the second type of thermistor detection is abnormal.

[0083] And when the dishwasher is in a non-water-intake stage and a flow meter pulse is detected, a first flow abnormality is determined.

[0084] When the dishwasher is in the water filling stage and the accumulated pulse is greater than the first preset pulse or less than the second preset pulse, a second flow abnormality is determined.

[0085] When the dishwasher is in the main wash stage or the rinsing stage and the power of the dishwasher cannot be reduced to the second preset power within the first preset time period, a first heating abnormality is determined.

[0086] The second heating abnormality is determined when the dishwasher is in the main wash stage or the rinse stage and the water-free protection is triggered.

[0087] When the dishwasher is in the main wash stage or the rinsing stage, the temperature of the thermistor is lower than the third preset temperature, and the power of the dishwasher is lower than the third preset power within the second preset time period, a third heating abnormality is determined.

[0088] When the dishwasher is in the drying stage, the power of the dishwasher is lower than the fourth preset power within the third preset time period, and a first type of fan abnormality is determined.

[0089] When the dishwasher is in the storage stage, the power of the dishwasher is lower than the fourth preset power within a fourth preset time period, and a second fan abnormality is determined.

[0090] When the single network abnormality feedback time lasts for a fifth preset time period, a first type of network abnormality is determined.

[0091] When the number of network abnormality feedbacks exceeds a preset number within a sixth preset time period, a second type of network abnormality is determined.

[0092] As the countdown increases, a first countdown anomaly is determined.

[0093] When the countdown decreases in accordance with the standard decrease logic within the unit time, a second countdown anomaly is determined.

[0094] The state of the regeneration gear does not match the corresponding number of regenerations, and the water intake during the cumulative regeneration period is greater than the non-regeneration water volume, resulting in regeneration abnormality.

[0095] The server can also use a display terminal to display non-routine faults and routine faults, and use different colors to distinguish them.

[0096] In some embodiments, when an exception or a fault occurs, the server stores the corresponding first test data and second test data to facilitate fault backtracing.

[0097] In this embodiment, a first data acquisition device is used to receive first test data collected by the home appliance during the test process of the home appliance; and a second data acquisition device is used to collect second test data of the home appliance during the test process, so as to increase the diversity and completeness of the collected test data and make up for the deficiencies in the test data type, and then the server is used to compare the data of the same type in the first test data and the second test data, and an abnormal prompt is given when an abnormality is found in the comparison; and the remaining test data in the first test data and the second test data are judged as unconventional faults and conventional faults respectively, and a fault prompt is given when a fault is judged to have occurred, wherein an unconventional fault refers to a fault that occurs but does not reach the point of triggering the built-in fault alarm in the home appliance and a fault that the home appliance itself cannot detect, and a conventional fault refers to a fault that occurs and reaches the point of triggering the built-in fault alarm in the home appliance. The first test data and the second test data can be used quickly and effectively to detect, monitor and warn the product performance and process of the home appliance, and abnormalities can be discovered in advance, thereby improving the test efficiency and the fault detection rate.
