To meet environmental protection requirements, more and more refrigerator products are advocating energy-saving designs. Among these, refrigerators generally achieve energy savings by using environmentally friendly refrigerants, thicker insulation layers, double door seals, and vacuum insulation panels. However, improving the energy efficiency of refrigerator compressors is difficult, resulting in poor energy-saving performance of refrigerators. Summary of the Invention

The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0056] This application provides a refrigerator control method, device, refrigerator, and computer-readable storage medium, which will be described in detail below. The computer-readable storage medium may be referred to as the storage medium.

[0057] The refrigerator control method in this embodiment of the invention is applied to a refrigerator control device, which is disposed in a refrigerator. The refrigerator is provided with one or more processors, a memory, and one or more application programs, wherein the one or more application programs are stored in the memory and configured to be executed by the processor to implement the refrigerator control method.

[0058] like Figure 1 As shown, Figure 1 This is a schematic diagram of a refrigerator control method according to an embodiment of the present application. The refrigerator control scenario in this embodiment includes a refrigerator 100 (the refrigerator 100 integrates a refrigerator control device), and the refrigerator 100 runs a computer-readable storage medium corresponding to the refrigerator control to execute the refrigerator control steps.

[0059] Understandable, Figure 1 The refrigerators in the refrigerator control method scenario shown, or the devices contained in the refrigerators, do not constitute a limitation on the embodiments of the present invention. That is, the number or type of refrigerators in the refrigerator control method scenario, or the number or type of devices contained in each refrigerator, do not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be considered as equivalent substitutions or derivatives of the technical solutions claimed in the embodiments of the present invention.

[0060] In this embodiment of the invention, the refrigerator 100 is mainly used for: obtaining the set temperature and actual temperature of the refrigerator compartment, and obtaining the ambient temperature; determining the compressor speed and expansion valve opening of the refrigerator based on the ambient temperature and the preset relationship between the ambient temperature and the parameters; determining the compartment damper opening based on the temperature difference between the actual temperature and the set temperature; and controlling the operation of the refrigerator based on the compressor speed, the expansion valve opening, and the compartment damper opening.

[0061] Those skilled in the art will understand that Figure 1 The application environment shown is merely one application scenario of the solution in this application and does not constitute a limitation on the application scenario of the solution in this application. Other application environments may include those that are more specific to this application. Figure 1 The number of refrigerators shown, or the refrigerator network connections, for example... Figure 1 Only one refrigerator is shown in the diagram. It is understood that the scenario of this refrigerator control method may also include one or more other refrigerators, which are not specifically limited here. The refrigerator 100 may also include a memory for storing data, such as storing refrigerator work information.

[0062] Furthermore, in the refrigerator control method scenario of this application, the refrigerator 100 can be equipped with a display device, or the refrigerator 100 can be connected to an external display device 200 without a built-in display device. The display device 200 is used to output the results of the refrigerator control method execution. The refrigerator 100 can access the background database 300 (the background database can be located in the refrigerator's local storage or it can be located in the cloud), and the background database 300 stores refrigerator control-related information.

[0063] It should be noted that, Figure 1 The schematic diagram of the refrigerator control method shown is merely an example. The scenarios of the refrigerator control method described in this embodiment are intended to more clearly illustrate the technical solutions of this embodiment and do not constitute a limitation on the technical solutions provided in this embodiment.

[0064] Based on the scenario described above for refrigerator control methods, an embodiment of the refrigerator control method is proposed.

[0065] like Figure 2 The diagram shown is a flowchart of an embodiment of the refrigerator control method in this application. The refrigerator control method includes steps S201-204:

[0066] S201. Obtain the set temperature and actual temperature of the refrigerator compartment, as well as the ambient temperature.

[0067] The ambient temperature refers to the ambient temperature of the environment in which the refrigerator is located.

[0068] The refrigerator compartment can be a refrigerator compartment or a freezer compartment. It is understood that a refrigerator generally includes at least one refrigerator compartment and at least one freezer compartment. It is understood that the refrigerator compartment can also be called the fresh food compartment. For example, the temperature of the refrigerator compartment of a refrigerator is generally above 0 degrees Celsius, and the temperature of the freezer compartment is generally below 0 degrees Celsius.

[0069] The actual temperature refers to the actual measured temperature inside the corresponding compartment of the refrigerated compartment, and / or the actual measured temperature inside the corresponding compartment of the frozen compartment.

[0070] Specifically, the refrigerator control method is applied to a refrigerator control device, which is installed in the refrigerator. The refrigerator can execute the refrigerator control method when it receives an energy-saving control command, or when the temperature reaches a preset temperature.

[0071] For example, in one embodiment of this application, when the refrigerator is running, if the temperature difference between the initial actual temperature and the set temperature of the refrigerator compartment is less than a preset temperature difference threshold, it indicates that the actual temperature inside the refrigerator compartment has approached the set temperature and no large amount of work is required. At this time, the influence of the ambient temperature is considered, that is, the ambient temperature is obtained, as well as the set temperature and the actual temperature of the refrigerator compartment are obtained.

[0072] S202. Based on the ambient temperature and the preset relationship between the ambient temperature and the parameters, determine the compressor speed and expansion valve opening of the refrigerator.

[0073] The preset relationship can be obtained based on ambient temperature, compressor speed and expansion valve opening.

[0074] For example, in one embodiment of this application, the compressor speed and expansion valve opening corresponding to the lowest power consumption at different ambient temperatures can be used as the optimal matching parameters, and a correspondence between the optimal matching parameters and the ambient temperature can be created.

[0075] For example, in another embodiment of this application, the outdoor ambient temperature can be divided into different temperature ranges, and the compressor speed and expansion valve opening corresponding to the lowest power consumption of the sample ambient temperature corresponding to the temperature range can be detected as the optimal matching parameters. A correspondence between the optimal matching parameters and the ambient temperature can be created. The sample ambient temperature can be the average temperature corresponding to the temperature range, or any stable temperature within the temperature range.

[0076] Specifically, after obtaining the ambient temperature, the refrigerator looks up the preset relationship between the temperature and the parameters to obtain the compressor speed and expansion valve opening corresponding to the ambient temperature.

[0077] S203. Determine the opening degree of the compartment damper based on the temperature difference between the actual temperature and the set temperature.

[0078] The opening degree of the compartment damper is used to control the air volume entering each compartment of the refrigerator.

[0079] Specifically, this application does not limit the specific implementation method of determining the compartment air damper opening of the refrigerator compartment based on the temperature difference value; an example is provided:

[0080] In one embodiment of this application, the damper opening is obtained by searching a preset mapping relationship corresponding to the damper opening or by obtaining the chamber damper opening corresponding to the temperature difference value.

[0081] S204. Control the operation of the refrigerator according to the compressor speed, the opening degree of the expansion valve and the opening degree of the compartment damper.

[0082] Specifically, after determining the compressor speed, the opening of the expansion valve, and the opening of the compartment damper, the refrigerator adjusts the compressor speed and the opening of the corresponding electronic expansion valve based on the compressor speed and the opening of the expansion valve. Furthermore, it controls the airflow into each refrigerator compartment based on the opening of the compartment damper. Specifically, the refrigerator adjusts the compressor speed based on the compressor speed; adjusts the opening of the electronic expansion valve based on the expansion valve opening; and adjusts the compartment damper opening based on the compartment damper opening.

[0083] This implementation scheme reduces compressor wear by adjusting the compressor's operating parameters when the actual temperature inside the refrigerator compartment is close to the set temperature and no significant work is required. It also ensures that the actual temperature inside the refrigerator is stable or approaches the set temperature by detecting the difference between the actual temperature and the set temperature.

[0084] Furthermore, based on the above implementation plan, see [link to relevant documentation]. Figure 3 , Figure 3 A flowchart illustrating one embodiment of the refrigerator control method for determining the opening degree of the intermediate compartment damper provided in this application includes steps S301-S303:

[0085] S301. Obtain the first temperature difference between the set temperature and the actual temperature of the refrigerator compartment, and the second temperature difference between the set temperature and the actual temperature of the freezer compartment.

[0086] Specifically, in this embodiment of the application, the set temperature and actual temperature of the refrigerator compartment and the set temperature and actual temperature of the freezer compartment are obtained, and a first temperature difference value between the set temperature and the actual temperature of the refrigerator compartment is calculated to assess the cooling demand of the refrigerator compartment. A second temperature difference value between the set temperature and the actual temperature of the freezer compartment is also calculated to assess the cooling demand of the freezer compartment.

[0087] S302. Based on the preset mapping relationship between temperature difference and damper opening, obtain the first damper opening range corresponding to the first temperature difference value and the second damper opening range corresponding to the second temperature difference value.

[0088] The first damper opening range includes multiple adjustable damper openings, and the second damper opening range includes multiple adjustable damper openings. It can be understood that since the work parameters are constant, that is, the air volume between the refrigerator compartment and the freezer compartment is actually related. If the damper opening is set to be mismatched with the air intake volume, it will affect the temperature preservation or temperature correction in the compartment. That is, this solution avoids the damper opening mismatch between the freezer compartment and the refrigerator compartment by setting a difference corresponding to a corresponding damper opening range.

[0089] Furthermore, after determining the first temperature difference value and the second temperature difference value, the first damper opening range corresponding to the first temperature difference value and the second damper opening range corresponding to the second temperature difference value are obtained by looking up the preset mapping relationship between the temperature difference and the damper opening.

[0090] Furthermore, in some other embodiments of this application, after determining the first temperature difference value and the second temperature difference value, the first damper opening corresponding to the first temperature difference value and the second damper opening corresponding to the second temperature difference value can also be directly obtained by looking up a preset mapping relationship between temperature difference and damper opening. It is understood that the preset mapping relationship can be designed according to actual needs.

[0091] S303. Extract the first damper opening and the second damper opening from the first damper opening range and the second damper opening range, respectively.

[0092] Furthermore, after obtaining the first damper opening range and the second damper opening range, the first damper opening and the second damper opening can be extracted from the first damper opening range and the second damper opening range, respectively. For example, any first damper opening can be selected from the first damper opening range, and the second damper opening that sums with the first damper opening to the maximum damper opening can be selected from the second damper opening range. It can be understood that the maximum damper opening is the opening corresponding to the maximum output of the output pipe at the refrigeration output end.

[0093] Furthermore, in one embodiment of this application, the first damper opening and the second damper opening are extracted from the first damper opening range and the second damper opening range, respectively, specifically including the following steps:

[0094] (1) Extract a first initial damper opening from the range of damper opening corresponding to the refrigerator compartment in descending order;

[0095] (2) For each of the first initial damper openings, if a second initial damper opening is found within the range of the second damper openings that has the maximum opening value when its opening is equal to the opening of the first initial damper opening, then the first initial damper opening is set as the first damper opening and the second initial damper opening is set as the second damper opening.

[0096] Specifically, in the implementation scheme of this application, under the condition that other system parameters (compressor speed and expansion valve opening are fixed) remain unchanged, the smaller the air distribution ratio of the refrigerator compartment, the slower the cooling rate of the refrigerator compartment. At the same time, the return air temperature of the refrigerator compartment has less impact on the evaporation temperature of the freezer evaporator. The system tends to maintain operation at a lower evaporation temperature for a long time, resulting in higher energy consumption. Conversely, the larger the air distribution ratio of the refrigerator compartment, the faster the cooling rate of the refrigerator compartment. At the same time, the return air of the refrigerator compartment has a greater impact on the evaporation temperature of the freezer evaporator. The system tends to operate intermittently between higher and lower evaporation temperatures. When the evaporation temperature is high, the energy consumption is also lower, but it is easy to cause insufficient cooling capacity in the freezer compartment. Therefore, there exists a refrigerator air distribution ratio that satisfies both the cooling capacity of the refrigerator and freezer compartments and minimizes the system's energy consumption.

[0097] That is, in the technical solution of this application, a first initial damper opening is first extracted from the damper opening range corresponding to the refrigerator compartment in descending order to ensure that the air volume corresponding to the refrigerator compartment is maximized. Further, the second initial damper opening is searched from small to large within the second damper opening range to obtain a second initial damper opening whose sum with the first initial damper opening is the maximum opening value. That is, the first initial damper opening and the second initial damper opening are the openings corresponding to the refrigerator air distribution ratio that satisfies both the cooling capacity of the refrigerator compartment and the freezer compartment and minimizes the system energy consumption. Then, the first initial damper opening is set as the first damper opening and the second initial damper opening is set as the second damper opening.

[0098] Furthermore, based on the above implementation scheme, this application also provides a method for creating preset relationships, see [link to relevant documentation]. Figure 4 , Figure 4 A flowchart illustrating one implementation scheme for creating a preset relationship in the refrigerator control method provided in this application includes steps S401-S403:

[0099] S401. Obtain the sample ambient temperature, and the compressor speed and expansion valve opening corresponding to the sample ambient temperature.

[0100] The sample ambient temperature, i.e. the temperature corresponding to the ambient temperature of the refrigerator, can be the measured temperature or the temperature corresponding to the temperature range described in the above implementation scheme.

[0101] For example, in one embodiment of this application, the sample environment temperature includes 32 degrees Celsius and 16 degrees Celsius, wherein 32 degrees Celsius represents the temperature corresponding to the temperature range above 24 degrees Celsius, and 16 degrees Celsius represents the temperature corresponding to the temperature range below 24 degrees Celsius. It is understood that the temperature is only for illustrative purposes, and the specific division of the temperature range is not specifically limited in this application.

[0102] The compressor speed and expansion valve opening corresponding to the sample ambient temperature are, for example, the compressor speed and expansion valve opening selectable under the sample ambient temperature conditions. For example, at an ambient temperature of 32 degrees Celsius, the commonly used compressor speeds are 1200 rpm, 1320 rpm, 1500 rpm, 1650 rpm, and 1820 rpm; at an ambient temperature of 16 degrees Celsius, the commonly used speeds for refrigerator power consumption testing are 950 rpm, 1000 rpm, 1050 rpm, 1100 rpm, and 1150 rpm.

[0103] S402. Input the compressor speed and expansion valve opening corresponding to the sample ambient temperature into the preset power consumption prediction model, and obtain the target compressor speed and target expansion valve opening of the power consumption prediction model under the condition of outputting the lowest power consumption.

[0104] Among them, under the sample ambient temperature conditions, the combination of target compressor speed and target expansion valve opening corresponds to the lowest power consumption.

[0105] Specifically, the compressor speeds and expansion valve openings corresponding to the sample ambient temperature can be pre-paired into multiple parameter groups. Each parameter group is then input into a preset power consumption prediction model, which outputs the minimum power consumption, as well as the target compressor speed and target expansion valve opening for the minimum power consumption. Alternatively, the compressor speeds and expansion valve openings corresponding to the sample ambient temperature can be input into a preset power consumption prediction model, which outputs the minimum power consumption, as well as the target compressor speed and target expansion valve opening for the minimum power consumption. It is understood that the power consumption prediction model can be trained based on a preset training model. The power consumption prediction model can have a random number selection function, that is, select any one of the compressor speeds and expansion valve openings to form a parameter group for further power consumption prediction. The power consumption prediction capability can be trained based on compressor speeds and expansion valve openings with power consumption labels. This application does not make specific limitations on these parameters.

[0106] S403. Update the preset relationship between the preset temperature and the parameters based on the correspondence between the sample ambient temperature, the target compressor speed and the target expansion valve opening.

[0107] Specifically, after obtaining the target compressor speed and the target expansion valve opening corresponding to the sample ambient temperature, a correlation is established between the sample ambient temperature, the target compressor speed, and the target expansion valve opening, and updated to the preset relationship between ambient temperature and parameters. Further, based on the ambient temperature and the preset relationship between ambient temperature and parameters, the compressor speed and expansion valve opening of the refrigerator are determined.

[0108] It is understandable that when the flow rate of the throttling system in the refrigeration system is constant (i.e., the solenoid valve opening is constant), the lower the compressor speed, the smaller the cooling capacity and the lower the system's energy consumption. However, when the cooling capacity is lower than the refrigerator's heat load, the actual temperature cannot drop to the set temperature, and the system cannot meet the design requirements. The higher the compressor speed, the greater the cooling capacity, but also the greater the energy consumption. Therefore, there is an optimal value for the compressor speed to minimize the refrigerator system's energy consumption and make its operation more reliable. When the compressor speed is constant, if the flow rate of the throttling system is too large, the throttling effect will be worse, the system's cooling capacity will decrease, and the system's energy consumption will increase. If the flow rate of the throttling system is too small, the cooling capacity of the refrigeration system will also decrease, and the system's energy consumption will increase. Therefore, there is an optimal matching point between the compressor speed and the flow rate of the throttling system to minimize the system's energy consumption, that is, to minimize power consumption.

[0109] Furthermore, based on the above implementation scheme, this application also provides an implementation scheme for updating a preset relationship. Specifically, after controlling the operation of the refrigerator according to the compressor speed, the opening degree of the expansion valve, and the opening degree of the compartment damper, the following steps are included:

[0110] (1) Obtain the actual power consumption of the refrigerator, and the power consumption difference between the actual power consumption and the minimum power consumption;

[0111] (2) If the power consumption difference is greater than the preset power consumption difference, the power consumption prediction model is updated based on the actual power consumption, the compressor speed and the expansion valve opening.

[0112] (3) The preset relationship between the ambient temperature and parameters is updated using the updated power consumption prediction model.

[0113] Specifically, the actual power consumption of the refrigerator can be detected and obtained through a power detection sensor. After controlling the refrigerator's operation based on the compressor speed, the expansion valve opening, and the compartment damper opening, the actual power consumption of the refrigerator can be monitored. The actual power consumption of the refrigerator is obtained according to a preset power collection frequency. The actual power consumption of the refrigerator is compared with the minimum power consumption corresponding to the compressor speed and the expansion valve opening. If the power consumption difference is greater than the preset power consumption difference, it indicates that the power consumption prediction error is large and will affect the recognition of the compressor speed and the expansion valve opening. Then, the power consumption prediction model is updated according to the actual power consumption, the compressor speed, and the expansion valve opening. For example, the actual power consumption is used as a label to predict the power consumption of the compressor speed and the expansion valve opening until the difference between the predicted power consumption and the actual power consumption is less than a preset threshold or is zero, thus obtaining an updated power consumption prediction model. Further, the above steps S401-S403 are repeated according to the updated power consumption prediction model to obtain an updated preset relationship.

[0114] Furthermore, based on the above implementation scheme, this application also provides another implementation scheme for a refrigerator control method, specifically including the following steps:

[0115] (1) Collect temperature data corresponding to the refrigerator compartment within a preset time period;

[0116] (2) Filter the temperature data and calculate the average temperature after filtering to obtain the average temperature;

[0117] (3) If the average temperature exceeds the temperature range corresponding to the refrigerator compartment, then feedback is provided on abnormal temperature acquisition.

[0118] (4) If the average temperature does not exceed the temperature range corresponding to the refrigerator compartment, the average temperature is set as the actual temperature of the refrigerator compartment.

[0119] (5) If the temperature difference between the actual temperature and the set temperature is less than the preset temperature difference threshold, then obtain the ambient temperature.

[0120] (6) Determine the compressor speed and expansion valve opening of the refrigerator based on the ambient temperature and the preset relationship between the ambient temperature and the parameters.

[0121] (7) Determine the opening degree of the compartment air damper of the refrigerator compartment based on the temperature difference between the actual temperature and the set temperature.

[0122] (8) Control the operation of the refrigerator according to the compressor speed, the opening degree of the expansion valve and the opening degree of the compartment damper.

[0123] Specifically, if the temperature sensor inside the refrigerator detects that the temperature difference between the initial actual temperature and the set temperature in all compartments (refrigerator and freezer compartments) is less than a preset temperature difference threshold, then the temperature data for each refrigerator and freezer compartment within a preset time period is collected. This temperature data includes multiple temperature data points. Further, the temperature data is filtered to remove abnormal temperature data, and the average temperature after filtering is calculated. If the average temperature does not exceed the temperature range of the corresponding compartment, the temperature detection is normal, and the average temperature is taken as the actual temperature of that compartment. If the average temperature exceeds the temperature range of the corresponding compartment, it indicates a possible malfunction in the actual temperature sensor, and abnormal temperature acquisition information is fed back. This can be achieved by issuing an audible and visual alarm or displaying the abnormal information to the user. The temperature range of the compartment refers to the temperature range corresponding to the refrigerator compartment and the temperature range corresponding to the freezer compartment.

[0124] Furthermore, based on the above implementation plan, see [link to relevant documentation]. Figure 5 , Figure 5 A schematic flowchart of another embodiment of the refrigerator control method provided in this application includes steps S501-S506:

[0125] S501. Obtain the set temperature and actual temperature of the refrigerator compartment, as well as the ambient temperature;

[0126] S502. Based on the ambient temperature and the preset relationship between the ambient temperature and the parameters, determine the compressor speed and expansion valve opening of the refrigerator.

[0127] S503. Determine the opening degree of the compartment damper based on the temperature difference between the actual temperature and the set temperature;

[0128] S504. Control the operation of the refrigerator according to the compressor speed, the opening degree of the expansion valve and the opening degree of the compartment damper;

[0129] For specific implementation schemes of steps S501-S504, please refer to any of the above implementation schemes.

[0130] S505. Obtain the actual temperature of each refrigerator compartment after a preset time.

[0131] Specifically, after the refrigerator controls the refrigerator to run for a preset time based on the compressor speed, the opening of the expansion valve, and the opening of the compartment damper, the actual temperature of each compartment in the refrigerator is obtained after the preset time, that is, the actual temperature of each refrigerator compartment and the actual temperature of each freezer compartment are obtained.

[0132] S506. If the temperature difference between the actual temperature and the set temperature of at least one of the refrigerator compartments is greater than a preset temperature difference threshold, then the opening degree of the compartment damper corresponding to the refrigerator compartment is increased.

[0133] Furthermore, the actual temperatures are compared with the set temperatures of the corresponding refrigerator compartments. If the temperature difference between at least one actual temperature and the set temperature is greater than a preset temperature difference threshold, the opening of the damper of at least one compartment corresponding to the actual temperature exceeding the preset temperature difference threshold is increased, while the opening of other dampers is decreased. For example, if the temperature difference between the actual temperature in the refrigerator compartment and the set temperature in the refrigerator compartment is greater than the preset temperature difference threshold, it indicates that the refrigerator temperature is far below the set temperature requirement. In this case, the opening of the damper corresponding to the refrigerator compartment is increased, while the opening of the damper in the freezer compartment is decreased. It is understood that if, after increasing the opening of the damper corresponding to the actual temperature for a preset period, the temperature difference between the actual temperature and the set temperature is still greater than the preset temperature difference threshold, the compressor speed is increased and / or the solenoid valve opening is increased until the temperature difference between the actual temperature and the set temperature is less than the preset temperature difference threshold. Then, the refrigerator operation is restored to be controlled based on the compressor speed, the expansion valve opening, and the damper opening. Furthermore, it can be understood that if the compressor speed and / or the solenoid valve opening are frequently increased within a preset time period, the preset relationship will be updated, and the operation will be controlled according to the refrigerator's initial control logic.

[0134] This application provides a refrigerator control method. It acquires the ambient temperature, as well as the set temperature and actual temperature of the refrigerator compartment. Based on the ambient temperature and a preset relationship between the ambient temperature and parameters, it determines the compressor speed and expansion valve opening. Based on the temperature difference between the actual temperature and the set temperature, it determines the compartment damper opening. The refrigerator operation is controlled based on the compressor speed, expansion valve opening, and compartment damper opening. This method combines ambient temperature to determine the corresponding compressor speed and expansion valve opening, ensuring that the compressor's work matches the ambient temperature and maximizing compressor efficiency. Simultaneously, it combines the set and actual temperatures of the refrigerator compartment to determine the compartment damper opening, ensuring stable compartment temperature, improving work efficiency, and ultimately enhancing the refrigerator's performance.
