[0002] A dual-system refrigerator means that the refrigerator and freezer compartments each have independent air supply and return systems and evaporators, and are not connected to each other, which can avoid the problem of odor transfer between the two compartments. At present, some dual-system refrigerators on the market have a drawer space in the refrigerator compartment that also forms a variable temperature chamber.

[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0043] An embodiment of the present application provides a control method for a refrigerator, wherein the refrigerator includes a first refrigeration component, a cold storage compartment, a temperature-changing chamber and a temperature-changing air door, the first refrigeration component is used to supply cold air to the cold storage compartment and the temperature-changing chamber through a first air supply port, and the first temperature-changing air door is arranged between the first air supply port and the temperature-changing chamber.

[0044] The first refrigeration component is a device for refrigeration, and the first refrigeration component may include a refrigeration evaporator, a refrigeration capillary, a refrigeration fan, etc. It should be noted that, for a refrigerator, its refrigeration system is not limited to the above-mentioned devices. For example, the refrigeration system of a refrigerator also includes a compressor and a condenser, which cooperate with the first refrigeration component to realize refrigeration of the refrigeration compartment. For the sake of convenience of explanation, the embodiments of the present application artificially define the refrigeration components of the refrigeration compartment and the freezer compartment separately, which should not be understood as a limitation on the refrigeration components.

[0045] The refrigerated compartment is a compartment for refrigerating and preserving food. The operating temperature range of the refrigerated compartment is usually 2°C to 8°C, and the food can be preserved for a short period of time, such as a week. The variable temperature room is a multifunctional food preservation room. The operating temperature range of the variable temperature room is -5°C to 4°C or lower, and different types of food can be preserved by freezing or refrigeration. The variable temperature room and the refrigerated compartment are arranged in the same space, and the two can be separated by a partition. The variable temperature room can be a space formed by drawers and partitions. The volume of the variable temperature room is, for example, smaller than that of the refrigerated compartment. There can also be a fruit and vegetable compartment for storing fruits and vegetables arranged side by side with the variable temperature room. The fruit and vegetable compartment has the same operating temperature as the refrigerated compartment. Setting up the fruit and vegetable compartment separately can prevent the fruit and vegetable compartment from having odor problems with the food in the refrigerated compartment.

[0046] It should be noted that the first refrigeration component supplies air to the cold storage room and the variable temperature room or stops supplying air to the cold storage room and the variable temperature room by turning on or off. The variable temperature air door is arranged between the first air supply port and the variable temperature room, and is used to open or close so that the first refrigeration component supplies air to the variable temperature room or prevent the first refrigeration component from supplying cold air to the variable temperature room. Exemplarily, the refrigerator controls the first refrigeration component to start or shut down according to the actual temperature of the cold storage room, that is, when the temperature of the cold storage room rises to the start-up point temperature, the first refrigeration component is controlled to start, and as the refrigeration time increases, when the temperature of the cold storage room decreases to the stop point temperature, the first refrigeration component is controlled to close. And the refrigerator also controls the variable temperature air door to open or close according to the temperature of the variable temperature room, that is, when the temperature of the variable temperature room rises to the start-up point temperature, the variable temperature air door is controlled to open so that the first refrigeration component supplies air to the variable temperature room, and as the refrigeration time increases, when the temperature of the variable temperature room decreases to the stop point temperature, the variable temperature air door is controlled to close to prevent the first refrigeration component from supplying air to the variable temperature room. The refrigerator in the embodiment of the present application does not have a refrigeration damper, which can reduce the number of components and save costs.

[0047] It is understandable that based on the above-mentioned air supply mechanism, the variable temperature chamber needs to passively follow the refrigerated compartment for cooling. Under ideal design conditions, the first air supply port is set to supply more air to the variable temperature chamber per unit time than to the refrigerated compartment, so that the variable temperature chamber can reach the shutdown point temperature before the refrigerated compartment, so that when the first refrigeration component is shut down, both the variable temperature chamber and the refrigerated compartment can reach the set temperature. However, for low-end refrigerator models, in order to save costs, the variable temperature chamber may only be formed by a simple drawer and a glass partition, resulting in poor insulation performance of the variable temperature chamber, which is easily affected by the external environment such as the temperature transfer of the refrigerated compartment, and thus it is difficult to reach the set temperature, resulting in poor storage effect.

[0048] Based on the above problems, the present application embodiment has improved the refrigeration control, please refer to Figure 1 , Figure 1This is a flow chart of a refrigerator control method provided in an embodiment of the present application. The refrigerator control method includes the following steps S101-S103:

[0049] Step S101: adjusting the second set temperature of the refrigerating compartment according to the first set temperature of the current temperature-changing chamber to obtain an adjusted target set temperature;

[0050] It should be noted that the temperature difference between the target set temperature and the first set temperature is smaller than the temperature difference between the second set temperature and the first set temperature.

[0051] The first set temperature is the storage temperature of the variable temperature chamber set by the user based on the current storage demand for the variable temperature chamber, and the second set temperature is the storage temperature of the refrigerated compartment set by the user based on the current storage demand for the refrigerated compartment. The first set temperature and the second set temperature can be set by the user through a control device of the refrigerator or a device such as a mobile terminal that communicates with the refrigerator. For example, the refrigerator is provided with a control panel, and the user can select or input the temperature parameter for the refrigerated compartment on the control panel to set the storage temperature of the refrigerated compartment.

[0052] In addition to the user directly setting the temperature parameters of the compartment, in some other embodiments, the refrigerator is preset with multiple storage modes for the variable temperature room and / or the refrigerated compartment, and different storage modes correspond to different storage parameters, including temperature parameters, humidity parameters, etc. The user can also select the required storage mode from the multiple storage modes to set the temperature of the variable temperature room or the refrigerated compartment. Exemplarily, the refrigerator is preset with an ice-cold mode, a meat storage mode, and a fruit and vegetable storage mode for the variable temperature room; wherein the temperature parameter corresponding to the ice-cold mode is -2°C, the temperature parameter corresponding to the meat storage mode is -1°C, and the temperature parameter corresponding to the fruit and vegetable storage mode is 2°C; when the user selects the ice-cold mode, the first set temperature is -2°C; when the user selects the meat storage mode, the first set temperature is -1°C; when the user selects the fruit and vegetable storage mode, the first set temperature is 2°C.

[0053] It is understandable that when the refrigerator adjusts the second set temperature of the refrigerating compartment according to the first set temperature of the current variable temperature compartment, it is also necessary to obtain the first set temperature and the second set temperature. For the temperature set by the user by selecting the storage mode, it may be necessary to analyze the storage mode currently selected by the variable temperature compartment and / or the refrigerating compartment to obtain the first set temperature and the second set temperature. In addition, before the user sets the temperature of the variable temperature compartment and the refrigerating compartment, the variable temperature compartment and the refrigerating compartment will operate at the default temperature set at the factory.

[0054] Step S102: in response to the door opening instruction for the variable temperature air door, controlling the variable temperature air door to open;

[0055] The variable temperature damper is a switch device that determines whether the variable temperature room is refrigerated. Before starting to refrigerate the variable temperature room, the variable temperature damper needs to be opened first to facilitate the cold air to enter the variable temperature room and act on the variable temperature room. Exemplarily, the variable temperature damper is an electric control component, for example, the variable temperature damper can be driven to open and close by a motor.

[0056] Exemplarily, a first temperature detection device is provided in the variable temperature chamber for detecting the actual temperature in the variable temperature chamber. When it is detected that the temperature of the variable temperature chamber reaches the start-up temperature point, the controller of the refrigerator controls the variable temperature damper to open; wherein, the start-up point temperature of the variable temperature chamber is related to the first set temperature. Exemplarily, the start-up point temperature of the variable temperature chamber is the same as the first set temperature, or the start-up point temperature of the variable temperature chamber is higher than the first set temperature, for example, by 1°C.

[0057] Step S103: in response to the power-on instruction for the first refrigeration component, control the first refrigeration component to start up to cool the refrigeration compartment and the variable temperature room so that the variable temperature room reaches the first set temperature and the refrigeration compartment reaches the target set temperature.

[0058] The first refrigeration component may include a refrigeration evaporator, a refrigeration fan, and a refrigeration capillary tube, etc. During refrigeration, the refrigeration fan blows air toward the first air supply port, so that the cold air generated by the compressor, condenser, and refrigeration evaporator can be blown to the room that needs to be refrigerated. At this time, the first refrigeration component can be controlled to supply cold air to the variable temperature room and the refrigerated room, that is, the cold air is transported to the variable temperature room and the refrigerated room through the variable temperature air duct and the refrigerated air duct respectively through the bifurcation of the first air supply port. The variable temperature room and the refrigerated room have return air ducts respectively, which form a cycle with the cold air, thereby refrigerating the variable temperature room and the refrigerated room.

[0059] Exemplarily, a second temperature detection device is provided in the refrigerated compartment to detect the actual temperature in the refrigerated compartment. When it is detected that the temperature of the refrigerated compartment reaches the start-up temperature point, the controller of the refrigerator controls the first refrigeration component to turn on; wherein the start-up point temperature of the refrigerated compartment is related to the target set temperature. Exemplarily, the start-up point temperature of the refrigerated compartment is higher than the target set temperature, for example, by 3°C.

[0060] Optionally, the temperature-changing damper is controlled to close when the temperature-changing chamber reaches a first set temperature, and the first refrigeration component is controlled to shut down when the refrigerated compartment reaches a target set temperature.

[0061] It should be noted that the second set temperature of the refrigerated compartment is adjusted according to the first set temperature of the current variable temperature compartment to obtain the target set temperature, and the refrigeration control of the refrigerated compartment is performed at the target set temperature, aiming to reduce the temperature difference between the set temperature of the variable temperature compartment and the set temperature of the refrigerated compartment. Since the temperature of the refrigerated compartment is maintained within the range of 0-10°C, it is considered to be in line with the design function of the refrigerated compartment. Therefore, the control method of the present application sacrifices the initial set temperature of the refrigerated compartment to reduce the heat transfer effect of the temperature of the refrigerated compartment on the variable temperature compartment, thereby ensuring that the variable temperature compartment can reach the storage temperature conditions required by the user.

[0062] The control method of the refrigerator provided in the embodiment of the present application can reduce the temperature difference between the set temperature of the variable temperature chamber and the set temperature of the refrigerated compartment by adjusting the second set temperature according to the first set temperature to obtain the target set temperature, and controlling the refrigeration of the refrigerated compartment based on the target set temperature, thereby reducing the heat transfer effect of the refrigerated compartment on the variable temperature chamber, ensuring that the variable temperature chamber can reach or approach the storage temperature conditions required by the user, thereby ensuring the storage effect of the variable temperature chamber.

[0063] In some embodiments, the control method of the refrigerator further includes: controlling the variable temperature chamber to reach a first set temperature in a first time period, and controlling the refrigerating compartment to reach a target set temperature in a second time period, wherein the first time period is less than the second time period.

[0064] Among them, the first time length for controlling the variable temperature chamber to reach the first set temperature is less than the second time length for the refrigerated compartment to reach the target set temperature, that is, the variable temperature chamber reaches the set temperature first. In this way, it can be avoided that when the refrigerated compartment reaches the target set temperature, the variable temperature chamber has not yet reached the first set temperature, but at this time the first refrigeration component has been turned off and cannot continue to supply air for cooling the variable temperature chamber, resulting in the variable temperature chamber being unable to reach the storage temperature required by the user.

[0065] As for how to make the first time length shorter than the second time length, the first refrigeration component can send cold air to the variable temperature room at the first cold air rate, and send cold air to the cold storage room at the second cold air rate, and the second cold air rate is smaller than the first cold air rate. The first cold air rate is set to be greater than the second cold air rate, that is, the amount of cold air reaching the variable temperature room per unit time is greater than the amount of cold air reaching the cold storage room. For example, the cross-section of the variable temperature air duct corresponding to the variable temperature room can be set to be greater than the cross-sectional area of ​​the cold storage air duct corresponding to the cold storage room, so that cold air is sent to the variable temperature air duct and the cold storage air duct at the same time through the air supply port, so that cold air is sent to the variable temperature room at the first cold air rate, and to the cold storage room at the second cold air rate, and the second cold air rate is smaller than the first cold air rate. In other words, the variable temperature room and the cold storage room are refrigerated at the same time, and in the air duct design, the air distribution ratio of the variable temperature room is sufficient, even if the working temperature of the variable temperature room is lower than that of the cold storage room, it will reach the working temperature before the cold storage room.

[0066] It is understandable that only when the temperature difference between the first set temperature of the variable temperature chamber and the second set temperature of the refrigerated compartment is too large, will it be difficult for the variable temperature chamber to reach the first set temperature. Therefore, when the temperature difference between the first set temperature and the second set temperature of the refrigerated compartment is not too large, there is no need to adjust the second set temperature of the refrigerated compartment. In this way, the refrigerated compartment can be kept at the temperature desired by the user, that is, the second set temperature set by the user, as much as possible, under the premise of ensuring that the variable temperature chamber can reach the first set temperature. As to how to measure whether the temperature difference between the first set temperature of the variable temperature chamber and the second set temperature of the refrigerated compartment is too large, the present application provides the following embodiment, which, before adjusting the second set temperature of the refrigerated compartment according to the first set temperature of the current variable temperature chamber, also includes:

[0067] Obtaining a preset heat transfer temperature difference;

[0068] calculating a first temperature difference between a first set temperature and a second set temperature;

[0069] If the first temperature difference is greater than the preset heat transfer temperature difference, the second set temperature of the refrigerating compartment is adjusted according to the first set temperature.

[0070] It should be noted that the preset heat transfer temperature difference represents the average temperature difference between the medium in the variable temperature chamber and the medium in the refrigerated compartment on the heating surface, such as the wall surface of the drawer and the partition forming the variable temperature chamber. It can be understood that the size of the preset heat transfer temperature difference reflects the thermal insulation performance of the variable temperature chamber. The larger the preset heat transfer temperature difference, the worse the thermal insulation performance of the variable temperature chamber, and the smaller the preset heat transfer temperature difference, the better the thermal insulation performance of the variable temperature chamber. The preset heat transfer temperature difference is preset by the designer, and the specific value of the preset heat transfer temperature difference can be confirmed by the designer based on actual experimental data.

[0071] If the first temperature difference is greater than the preset heat transfer temperature difference, it can be explained that the temperature difference between the first set temperature and the second set temperature is too large; if the refrigeration of the cold storage room is controlled based on the second set temperature, it is easy to cause the variable temperature room to be affected by the greater heat transfer of the cold storage room and it is difficult to reach the first set temperature; therefore, at this time, the second set temperature needs to be adjusted to reduce the heat transfer effect of the cold storage room on the variable temperature room, thereby ensuring that the variable temperature room can easily reach or approach the first set temperature and achieve its storage effect.

[0072] In some embodiments, if the first temperature difference is less than or equal to the preset heat transfer temperature difference, the second set temperature may not be adjusted, that is, the first refrigeration component is controlled to shut down when the refrigerating compartment reaches the second set temperature.

[0073] The present application further describes how to adjust the second set temperature. Exemplarily, adjusting the second set temperature of the refrigerated compartment according to the first set temperature to obtain the adjusted target set temperature may include:

[0074] Calculating the sum of the first set temperature and the preset heat transfer temperature difference to obtain a first adjustment temperature;

[0075] The second set temperature is adjusted based on the first adjustment temperature to obtain a target set temperature.

[0076] It should be noted that, based on the operating temperature range of the refrigerated compartment and the variable temperature compartment, it can be known that the first set temperature of the variable temperature compartment is lower than or close to the second set temperature of the refrigerated compartment, that is, when the second set temperature needs to be adjusted, the first set temperature is less than or equal to the temperature obtained by subtracting the preset heat transfer temperature difference from the second set temperature.

[0077] The target setting temperature is less than or equal to the first adjustment temperature. Optionally, the target setting temperature is the same as the first adjustment temperature, or the target setting temperature is equal to the difference between the first adjustment temperature and a preset temperature such as 0 to 1°C. For example, if the first setting temperature is -2°C and the preset heat transfer temperature difference is 6°C, the first adjustment temperature is 4°C and the target setting temperature is determined to be 4°C; if the first setting temperature is -1°C and the preset heat transfer temperature difference is 6°C, the first adjustment temperature is 5°C and the target setting temperature is determined to be 5°C.

[0078] Regarding how to adjust the second set temperature, the present application also provides another implementation mode, wherein adjusting the second set temperature of the refrigerated compartment according to the first set temperature to obtain the adjusted target set temperature may include:

[0079] Determine a first adjustment temperature according to the first temperature difference, wherein the first temperature difference is positively correlated with the first adjustment temperature;

[0080] The second set temperature is adjusted based on the first adjustment temperature to obtain a target set temperature.

[0081] It can be understood that the first temperature difference is positively correlated with the first adjustment temperature, and the greater the temperature difference between the first set temperature of the variable temperature chamber and the second set temperature of the refrigerated compartment, the greater the first adjustment temperature, and the greater the adjustment range for the second set temperature. Exemplarily, the first adjustment temperature may be 1 / k times the first temperature difference; or, determining the first adjustment temperature according to the first temperature difference includes: obtaining a mapping relationship collection, the mapping relationship collection including a one-to-one correspondence between multiple preset temperature differences and multiple preset adjustment temperatures; and determining the first adjustment temperature corresponding to the first temperature difference from the multiple preset adjustment temperatures based on the mapping relationship collection.

[0082] Optionally, adjusting the second set temperature based on the first adjustment temperature to obtain the target set temperature includes calculating the difference between the second set temperature and the first adjustment temperature as the target set temperature. Exemplarily, the first set temperature is -2°C, the preset heat transfer temperature difference is 6°C, the first temperature difference is 8°C, the first adjustment temperature is determined to be 2°C, and the target set temperature is determined to be 4°C.

[0083] It is understandable that when the first set temperature of the variable temperature chamber is low, for example, below 0°C, and the variable temperature chamber is used to store fresh food and other items that need to be frozen, then it is necessary to strictly require that the variable temperature chamber can reach the required low temperature, otherwise it will be difficult to achieve the storage purpose, and it is easy to cause problems such as food spoilage. However. When the first set temperature of the variable temperature chamber itself is high, for example, above 0°C, and the variable temperature chamber is used to store fruits and vegetables, even if the temperature difference with the second set temperature of the refrigerated compartment is large, it does not affect the variable temperature chamber to achieve its storage function, and the second set temperature of the refrigerated compartment can be adjusted to ensure that the temperature of the refrigerated compartment meets user needs. In some embodiments, before obtaining the preset heat transfer temperature difference, it also includes:

[0084] Obtaining a first preset temperature;

[0085] If the first set temperature of the current temperature-changing chamber is less than the first preset temperature, the preset heat transfer temperature difference is obtained.

[0086] If the first set temperature of the current variable temperature chamber is greater than or equal to the first preset temperature, the first refrigeration component is controlled to shut down when the refrigerated compartment reaches the second set temperature, and the second set temperature set by the user is used as the shutdown point temperature of the refrigerated compartment. For example, the first preset temperature is 0°C, and when the first set temperature of the variable temperature chamber is not lower than 0°C, the second set temperature of the refrigerated compartment is not adjusted.

[0087] The control method of the refrigerator provided in the embodiment of the present application can reduce the temperature difference between the set temperature of the variable temperature chamber and the set temperature of the refrigerated compartment by adjusting the second set temperature according to the first set temperature to obtain the target set temperature, and controlling the refrigeration of the refrigerated compartment based on the target set temperature, thereby reducing the heat transfer effect of the refrigerated compartment on the variable temperature chamber, ensuring that the variable temperature chamber can reach or approach the storage temperature conditions required by the user, thereby ensuring the storage effect of the variable temperature chamber.

[0088] The present application also provides a refrigerator control device. For example, see Figure 2 , Figure 2 The schematic diagram of the structure of the control device of the refrigerator provided in the embodiment of the present application is as follows: The control device 200 of the refrigerator includes an adjustment module 210 and a control module 220 .

[0089] The adjustment module 210 is used to adjust the second set temperature of the refrigerated compartment according to the first set temperature of the current variable temperature room to obtain the adjusted target set temperature. The control module 220 is used to: respond to the door opening instruction for the variable temperature air door, control the variable temperature air door to open; respond to the power-on instruction for the first refrigeration component, control the first refrigeration component to start up to cool the refrigerated compartment and the variable temperature room; control the variable temperature air door to close when the variable temperature room reaches the first set temperature, and control the first refrigeration component to shut down when the refrigerated compartment reaches the target set temperature.

[0090] The control device of the refrigerator provided in the embodiment of the present application can reduce the temperature difference between the set temperature of the variable temperature chamber and the set temperature of the refrigerated compartment by adjusting the second set temperature according to the first set temperature to obtain the target set temperature, and performing refrigeration control on the refrigerated compartment based on the target set temperature, thereby reducing the heat transfer effect of the refrigerated compartment on the variable temperature chamber, ensuring that the variable temperature chamber can reach or approach the storage temperature conditions required by the user, thereby ensuring the storage effect of the variable temperature chamber.

[0091] The present application also provides a refrigerator, for example, see Figure 3-Figure 5 , Figure 3 This is a schematic diagram of the first structure of the refrigerator provided in the embodiment of the present application. Figure 4 A second structural schematic diagram of a refrigerator provided in an embodiment of the present application, Figure 5 The third structural diagram of the refrigerator provided in the embodiment of the present application is shown in FIG. Figure 3 The cross door refrigerator shown in the figure or Figure 4 The refrigerator 300 includes a refrigerating compartment 310 , a temperature-changing chamber 320 , a first refrigerating assembly 330 , a temperature-changing air door 340 , a freezing compartment 350 , a second refrigerating assembly 360 , a first air outlet 370 , and a second air outlet 380 .

[0092] Among them, the refrigeration compartment 310 is used for refrigerating food, that is, it is a compartment for refrigerating and preserving food. The operating temperature range of the refrigeration compartment 310 can be 2°C to 8°C, which is suitable for preserving food for a short period of time such as a week. The freezing compartment 350 is used for freezing and preserving food. The operating temperature range of the freezing compartment 350 can be -24°C to -15°C. The variable temperature chamber 320 is a multifunctional food preservation chamber. The operating temperature range of the variable temperature chamber 320 is -5°C to 4°C, and different types of food can be preserved by freezing or refrigeration. The variable temperature chamber 320 and the refrigeration compartment 310 are arranged in the same space. For example, the refrigeration compartment 310 can be separated by a partition, and the variable temperature chamber 320 can be formed by a drawer and a partition. Typically, the volume of the variable temperature chamber 320 may be smaller than that of the refrigerated compartment 310, and a fruit and vegetable compartment may be arranged side by side with the variable temperature chamber 320 for storing fruits and vegetables. The working temperature of the fruit and vegetable compartment is the same as that of the refrigerated compartment 310. Setting up the fruit and vegetable compartment separately can prevent the fruit and vegetable compartment from having odor contamination with the food in the refrigerated compartment 310.

[0093] The first refrigeration assembly 330 is used to supply cold air to the refrigeration compartment 310 and the variable temperature compartment 320 through the first air supply port 370. The first refrigeration assembly 330 may include a refrigeration evaporator, a refrigeration capillary tube, and a refrigeration fan. The variable temperature air door 340 is disposed between the first air supply port 370 and the variable temperature compartment 320 to supply air to the variable temperature compartment 320 or prevent air from being supplied to the variable temperature compartment 320.

[0094] The second refrigeration assembly 360 is used to supply air to the freezing compartment 350 through the second air supply port 380. The second refrigeration assembly 360 may include a freezing evaporator, a freezing capillary tube, and a freezing fan. It is understandable that the refrigerating compartment 310 and the freezing compartment 350 of the refrigerator 300 each have an independent air supply and return system and evaporator, and are not connected to each other, which can avoid the problem of odor transfer between the two compartments.

[0095] The refrigerator 300 may further include a compressor and a condenser, which cooperate with the first refrigeration assembly 330 and the second refrigeration assembly 360 respectively to realize refrigeration of the refrigerating compartment 310 and the freezing compartment 350 respectively.

[0096] The refrigerator 300 may further include a processor 390, which is used to adjust the second set temperature of the refrigerating compartment 310 according to the first set temperature of the current variable temperature chamber 320 to obtain an adjusted target set temperature; in response to an opening instruction for the variable temperature air door 340, control the variable temperature air door 340 to open; in response to a power-on instruction for the first refrigeration component 330, control the first refrigeration component 330 to start up to cool the refrigerating compartment 310 and the variable temperature chamber 320; control the variable temperature air door 340 to close when the variable temperature chamber 320 reaches the first set temperature, and control the first refrigeration component 330 to shut down when the refrigerating compartment 310 reaches the target set temperature.

[0097] The refrigerator 300 provided in the embodiment of the present application can reduce the temperature difference between the set temperature of the variable temperature chamber 320 and the set temperature of the refrigerating chamber 310 by adjusting the second set temperature according to the first set temperature to obtain the target set temperature, and performing refrigeration control on the refrigerating chamber 310 based on the target set temperature, thereby reducing the heat transfer effect of the refrigerating chamber 310 on the variable temperature chamber 320, ensuring that the variable temperature chamber 320 can reach or approach the storage temperature condition required by the user, thereby ensuring the storage effect of the variable temperature chamber 320.

[0098] The embodiment of the present application also provides a storage medium on which a computer program is stored, and when the computer program is run, the above-mentioned refrigerator control method is executed. Among them, the storage medium may include: a read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk, etc., which can store program codes.
