[0047] In this application, the word "exemplary" is used to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations. The following description is presented to enable any person skilled in the art to make and use the application. For purposes of explanation, specific details are set forth in order to provide a thorough understanding of the application. It will be apparent to one skilled in the art, however, that the application can be practiced without the specific details presented herein. In other instances, well known structures and processes are not elaborated in order to avoid obscuring the subject matter of this application. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features presented herein.

[0048] The application provides a test control method, device, server and storage medium for storage temperature of a single-system refrigerator.

[0049] As shown in FIG. 1, it is a flowchart of an embodiment of the test control method for storage temperature of a single-system refrigerator in the application, which comprises the following steps. Figure 1

[0050] S200, obtaining a test instruction;

[0051] S400, obtaining a refrigeration temperature in a refrigeration chamber;

[0052] S500, if the refrigeration temperature reaches a start-up point temperature, controlling a compressor to start up and run;

[0053] S600, after the compressor runs for a first preset time length, controlling a fan to start up and run; the fan is configured to provide cold air to the refrigeration chamber and a freezing chamber.

[0054] In the technical solution of the application, when the storage temperature test is performed, a test instruction is obtained to indicate the single-system refrigerator to enter a storage temperature test mode. By obtaining the refrigeration temperature in the refrigeration chamber, when the refrigeration temperature reaches a start-up point temperature, the compressor is controlled to start up and run, while the fan does not start up. After the compressor runs for a first preset time length, the fan starts up and runs; the fan is used to provide cold air to the refrigeration chamber and the freezing chamber, so that the refrigeration chamber and the freezing chamber start to cool down. By delaying the fan to start up and run for a first preset time length, the temperature in the refrigeration chamber can be increased during the test, and the refrigeration time can be prolonged, so that the freezing chamber has a significant cooling effect, which helps to improve the efficiency of the storage temperature test without frequent gear adjustment.

[0055] ​It should be noted that the refrigeration system of the single-system air-cooled refrigerator comprises a compressor, a condenser, a throttling device and an evaporator. The refrigerant is compressed by the compressor, enters the condenser to release heat, is throttled and reduced in pressure by the throttling device, and then enters the evaporator. The refrigerant in the evaporator is used to provide cold energy for refrigeration. The heat-exchanged refrigerant reenters the compressor. The fan is used to bring the cold air exchanged with the evaporator into the freezer compartment and the refrigerator compartment. In the single-system air-cooled refrigerator, the evaporator is arranged in the freezer compartment or close to the freezer compartment. Therefore, when the compressor is started and the fan is not started, the evaporator can keep the freezer compartment in a relatively stable state; and since the fan is not started, the refrigeration temperature in the refrigerator compartment will gradually increase. Thus, when the refrigeration temperature reaches the starting point temperature, the compressor is started, and at this time the fan does not rotate, the temperature of the refrigerator compartment continues to rise, and the temperature of the freezer compartment remains stable; therefore, the fan is started to start refrigeration in the refrigerator compartment, and since the temperature of the refrigerator compartment rises, the refrigeration time is significantly prolonged, and the temperature is significantly lowered, which helps to improve the efficiency of the storage temperature test.

[0056] In embodiments, the starting point temperature is a preset value; for the storage temperature test, the starting point temperature is 0-4℃.

[0057] In embodiments, the first preset time length can be 5-15 minutes; for example, in some embodiments, the first preset time length is 10 minutes. By delaying the start of the fan, the refrigeration temperature in the refrigerator compartment can be increased, and thus the shutdown running time of the refrigerator can be delayed.

[0058] When performing the storage temperature test, the experimenter transports the refrigerator to the laboratory bench, and puts the pressurized load in the freezer compartment to simulate the normal loading condition of the user; among the pressurized load, several loads can be sensed by the temperature sensor; the refrigerator compartment is directly used for temperature detection, which is equivalent to the condition of empty load. The requirements of the storage temperature test on the refrigerator according to the old European standard or the new European standard are that the starting point temperature of the refrigerator compartment is 0-4℃, and the maximum temperature of the pressurized load in the freezer compartment does not exceed -18℃ (in the stable stage, in the non-defrosting stage). After the control method of delaying the start of the fan is adopted, the refrigeration temperature sensor detects the starting point temperature, at which time the compressor is started, and the fan is not started to drive the air cooling; within the first preset time length of 10 minutes of the delayed start of the fan, the temperature of the refrigerator compartment will increase, and the temperature of the pressurized load in the freezer compartment remains unchanged; after 10 minutes, the fan is started, at which time the refrigerator compartment needs a longer time for refrigeration to reach the refrigeration shutdown point, which is equivalent to prolonging the refrigeration time, providing sufficient cooling time for the 11 pressurized load in the freezer compartment, so as to meet the requirements of the refrigerator compartment on the starting point temperature of 0-4℃ and the requirement of the freezer compartment on the maximum temperature of not exceeding -18℃, so as to achieve the purpose of improving the test efficiency.

[0059] AsFigure 2 As an optional implementation of the above embodiment, the test control method further includes:

[0060] S700, if the refrigeration temperature reaches the shutdown point temperature, controlling the compressor to shut down and controlling the fan to shut down.

[0061] In the technical solution of the embodiment, when the refrigeration temperature reaches the shutdown point temperature, the compressor and the fan are both shut down, and the refrigerator stops refrigeration. In the embodiment, the refrigeration temperature is an operation index for the refrigerator to provide refrigeration and stop refrigeration. When the refrigeration sensor measures that the refrigeration temperature reaches the startup point temperature, at this time, the compressor is started, the fan is not started, the refrigeration chamber cannot perform refrigeration, the temperature of the refrigeration chamber continues to rise, and the temperature of the freezing chamber remains stable due to the action of the evaporator. After the first preset time length, the fan is started, at this time, the fan is started to refrigerate the refrigeration chamber and also refrigerate the freezing chamber. Due to the rise in the temperature of the refrigeration chamber just now, a longer refrigeration time is required, and the refrigeration temperature reaches the shutdown point temperature, thereby prolonging the refrigeration time of the refrigerator and further helping to improve the test efficiency and pass rate of the storage temperature test.

[0062] As shown in Figure 3 As an optional implementation of the above embodiment, after the step of if the refrigeration temperature reaches the shutdown point temperature, controlling the compressor to shut down and controlling the fan to shut down, the method further includes:

[0063] S800, acquiring a load temperature in the freezing chamber.

[0064] S900, judging whether the single-system refrigerator passes the storage temperature test according to the load temperature and a first preset threshold value.

[0065] In the embodiment, a load for testing is placed in the freezing chamber. The load temperature and the first preset threshold value are acquired to judge whether the single-system refrigerator passes the storage temperature test. The first preset threshold value is set according to the requirements of the storage temperature test, for example, the first preset threshold value is -18℃ for the test requirements of the old European standard or the new European standard.

[0066] As shown in Figure 4 As an optional implementation of the above embodiment, the step of judging whether the single-system refrigerator passes the storage temperature test according to the load temperature and a first preset threshold value includes:

[0067] S910, if the load temperature is less than or equal to the first preset threshold value, controlling to output a first test result; the first test result is used to indicate that the single-system refrigerator passes the storage temperature test.

[0068] S920, if the load temperature is greater than the first preset threshold, output a second test result; the second test result is used to indicate that the single-system refrigerator fails the storage temperature test.

[0069] In an embodiment, when the load temperature is less than or equal to the first preset threshold, it indicates that the storage temperature test is passed, and a first test result is output. The first test result can be in the form of text, sound, pattern identification, color identification, etc. The first test result can be displayed on the test equipment of the test bench or on the test terminal in communication connection with the test equipment. For example, the first test result can be in the form of text "pass the test", sound "pass the test", pattern identification "pass the test", or green identification indicating passing the test, etc.

[0070] In an embodiment, when the load temperature is greater than the first preset threshold, it indicates that the storage temperature test is failed, and a second test result is output. The second test result can be in the form of text, sound, pattern identification, color identification, etc. The second test result can be displayed on the test equipment of the test bench or on the test terminal in communication connection with the test equipment. For example, the second test result can be in the form of text "fail the test", sound "fail the test", pattern identification "fail the test", or red indicating failing the test, etc.

[0071] As shown in Figure 5 As an optional implementation of the above embodiment, the test control method further comprises:

[0072] S110, acquiring an ambient temperature;

[0073] S120, determining whether the ambient temperature is lower than a second preset threshold;

[0074] S130, if yes, outputting a permission instruction of the test;

[0075] S140, if no, outputting a prompt instruction; the prompt instruction is used to prompt that the ambient temperature needs to be reduced to the second preset threshold;

[0076] The acquiring of the refrigeration temperature in the refrigeration chamber comprises:

[0077] In response to the permission instruction, the refrigeration temperature in the refrigeration chamber is acquired.

[0078] According to the test requirement of the storage temperature, the storage temperature test needs to be conducted under the environmental temperature condition lower than the second preset threshold. Therefore, when the test is conducted, the environmental temperature needs to be judged. When the environmental temperature exceeds the second preset threshold, a prompt instruction needs to be output to prompt the experimenter that the environmental temperature needs to be reduced to the second preset threshold, so that the experimenter reduces the environmental temperature to below the second preset threshold. If the environmental temperature is lower than or equal to the second preset threshold, an allowable instruction of the test is output. At this time, in response to the allowable instruction, the refrigeration temperature in the refrigeration chamber is acquired to start the storage temperature test.

[0079] In an embodiment, the second preset threshold is 10℃, that is, the refrigeration temperature test needs to be conducted in an environment not greater than 10℃,

[0080] In an embodiment, when the storage temperature test is conducted, steps S110-S140 can be executed, and then step S200 is executed; in some embodiments, steps S110-S140 and step S200 can be executed synchronously; in some embodiments, step S200 can be executed first, and then steps S110-S140 are executed.

[0081] As shown in FIG. 10, as an optional implementation of the above embodiment, the test control method further includes: Figure 6

[0082] S300, in response to the test instruction, controlling the single-system refrigerator to enter a refrigeration working mode.

[0083] In an embodiment, after the system acquires the test instruction, the single-system refrigerator enters the refrigeration working mode. That is, it starts to judge whether the refrigeration temperature exceeds the start-up point temperature, and whether the compressor runs for the first preset time length, and starts to control the fan to run after the compressor runs for the first preset time length. In addition, it starts to judge whether the refrigeration temperature is lower than the shutdown point temperature, and controls the compressor and the fan to stop when the refrigeration temperature is lower than the shutdown point temperature.

[0084] The single-system refrigerator also has other running modes, such as a defrosting mode. When the storage temperature test is conducted, the single-system refrigerator only runs in the refrigeration working mode.

[0085] As shown in FIG. 10, as an optional implementation of the above embodiment, the test control method further includes: Figure 7

[0086] S610, after the compressor runs for the first preset time length, acquiring a temperature difference between the refrigeration temperature of the refrigeration chamber and the load temperature in the freezing chamber;

[0087] S620, if the temperature difference reaches a preset temperature difference, controlling the fan to run; ​​

[0088] S630, if the temperature difference is less than the preset temperature difference, controlling the fan to start running after a second preset time length.

[0089] In the technical scheme of the embodiments of the present application, in order to further improve the test efficiency of the storage temperature test, after the compressor is started to run for a first preset time length, whether to control the fan to start or delay the start of the fan is determined according to the temperature difference between the refrigeration temperature and the load temperature. After the compressor is started, the load temperature does not change much because the evaporator can provide cold energy to the freezer chamber, while the refrigeration temperature increases. By comparing the temperature difference with the preset temperature difference, the rising amplitude of the refrigeration temperature can be determined. That is, the higher the refrigeration temperature rises after the compressor is started to run for a first preset time length, the more the fan is controlled to start running. The lower the refrigeration temperature rises after the compressor is started to run for a first preset time length, the longer the second preset time length is extended before the fan is controlled to start running, so that the refrigeration temperature rises by a certain amplitude, which helps to extend the refrigeration time of the refrigerator.

[0090] In order to better implement the test control method of the storage temperature of the single-system refrigerator in the embodiments of the present application, on the basis of the test control method of the storage temperature of the single-system refrigerator, the present application further provides a test control device for the storage temperature of a single-system refrigerator, as shown in Figure 8 The test control device for the storage temperature of the single-system refrigerator comprises:
