Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, and for example, to a refrigerator refrigeration control method, a refrigerator refrigeration control device and a refrigerator. Background Art

[0002] Currently, refrigerators have the function of keeping food fresh. After a user puts food into the refrigerator compartment, the refrigerator refrigerates the compartment to lower the temperature of the stored food and keep the food fresh.

[0003] In daily life, users sometimes put a small amount of food into the refrigerator compartment, and sometimes put a large amount of food into the refrigerator compartment. In order to cope with such usage scenarios, some refrigerators are provided with a weight detection device for detecting the weight change of the stored objects (such as food) in the refrigerator compartment, and calculating the refrigeration capacity required for the refrigerator compartment according to the weight change of the stored objects, and then controlling the refrigerator according to the refrigeration capacity.

[0004] In the process of implementing the embodiments of the present application, it is found that there are at least the following problems in the related technology:

[0005] Under ideal conditions, the temperature of the stored objects placed in the refrigerator compartment is room temperature, and the amount of cold required in the process of cooling the stored objects from room temperature to the set temperature in the refrigerator compartment is the refrigeration capacity of the refrigerator. However, in practice, the temperature of the stored objects placed in the refrigerator is uncontrollable, which makes it difficult to accurately calculate the refrigeration capacity required by the refrigerator compartment after the stored objects are placed in the refrigerator compartment; in addition, if the mass of the stored objects placed in the refrigerator compartment is the same, if the volume and shape of the stored objects are different, and the placement position in the refrigerator compartment is different, the refrigeration effect of the refrigerator compartment itself will change, which also makes it difficult for the refrigerator to provide coldness to the refrigerator compartment according to the pre-calculated refrigeration capacity. The uncontrollable amount of coldness required for the stored objects placed in the refrigerator and the uncontrollable amount of coldness provided by the refrigerator to the compartment both create obstacles to the process of achieving the expected effect of the above-mentioned prior art, and easily lead to the phenomenon that the demand for coldness of the stored objects stored in the refrigerator compartment and the coldness that the refrigerator compartment can provide for the stored objects do not match each other, thereby reducing the preservation effect of the stored objects in the refrigerator compartment.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0007] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0008] The embodiments of the present application provide a refrigeration control method, device and refrigerator for a refrigerator, which combines a conventional refrigeration operation mode with a large-storage refrigeration operation mode to implement a relatively fuzzy control strategy for refrigeration capacity based on the set temperature in the conventional refrigeration operation mode, thereby ultimately improving the preservation effect of indoor storage items in the refrigerator.

[0013] Optionally, the conditions for determining whether the volume of the item meets the criteria for determining whether the item is a large-volume item include one or more of the following:

[0014] First condition: the volume of the item is greater than or equal to the first volume threshold;

[0015] Second condition: the remaining space of the compartment is less than or equal to the second volume threshold;

[0016] The third condition: the ratio of the volume of the article to the volume of the compartment is greater than or equal to the first ratio threshold;

[0017] Fourth condition: the ratio of the volume of the article to the remaining volume of the compartment is greater than or equal to the second ratio threshold.

[0018] Optionally, controlling the refrigerator to switch from a conventional refrigeration operation mode to a bulk storage refrigeration operation mode includes: adjusting a solenoid valve and / or a compressor of the refrigerator compartment to increase a refrigeration rate for the refrigerator compartment; and / or adjusting a fan and / or a damper of the refrigerator compartment to increase an air flow rate in the refrigerator compartment.

[0019] Optionally, the refrigerator includes a refrigerating chamber and a freezing chamber.

[0020] Optionally, controlling the refrigerator to switch from a conventional refrigeration operation mode to a large-volume storage refrigeration operation mode includes: when the refrigerator compartment is a cold storage compartment, controlling the refrigerator to switch from a first conventional refrigeration operation mode to a first large-volume storage refrigeration operation mode; when the refrigerator compartment is a freezer compartment, controlling the refrigerator to switch from a second conventional refrigeration operation mode to a second large-volume storage refrigeration operation mode; wherein a set temperature in the first conventional refrigeration operation mode is lower than a set temperature in the second conventional refrigeration operation mode; and a refrigeration rate in the first large-volume storage refrigeration operation mode is lower than a refrigeration rate in the second large-volume storage refrigeration operation mode.

[0021] In some embodiments, a refrigeration control device of a refrigerator includes an acquisition module, a first control module, and a second control module; the acquisition module is used to obtain the volume of items newly stored in a refrigerator compartment when the refrigerator is in a conventional refrigeration operation mode; the first control module is used to control the refrigerator to switch from the conventional refrigeration operation mode to the large-volume storage refrigeration operation mode when the volume of the items meets the judgment conditions of large-volume items; the second control module is used to control the refrigerator to switch from the large-volume storage refrigeration operation mode back to the conventional refrigeration operation mode after the temperature of the compartment is less than or equal to a temperature threshold; wherein the refrigeration rate of the refrigerator for the compartment in the conventional refrigeration operation mode is less than the refrigeration rate of the refrigerator for the compartment in the large-volume storage refrigeration operation mode, and the temperature threshold is determined according to the set temperature in the conventional refrigeration operation mode.

[0022] In some embodiments, a refrigeration control device for a refrigerator includes a processor and a memory storing program instructions, and the processor is configured to execute the refrigeration control method for the refrigerator provided in the above embodiments when executing the program instructions.

[0023] In some embodiments, the refrigerator includes a refrigerator body and a refrigeration control device of the refrigerator provided in the aforementioned embodiments, and the refrigeration control device is installed on the refrigerator body.

[0024] The refrigerator refrigeration control method, device and refrigerator provided in the embodiments of the present application can achieve the following technical effects:

[0025] After newly added storage items are added to the refrigerator compartment, if the volume of the newly added storage items meets the judgment conditions for large-volume items, it means that the newly added storage items have caused a significant increase in the demand for cooling capacity in the refrigerator compartment, and / or, it means that the newly added storage items have caused a significant decrease in the ability of the refrigerator to provide cooling capacity to the compartment. At this time, the refrigerator is controlled to switch from the conventional refrigeration operation mode to the large-storage refrigeration operation mode to increase the refrigeration rate for the compartment. A higher refrigeration rate for the compartment means a higher rate of providing cooling capacity to the compartment, so as to meet the cooling capacity demand of the newly added storage items as much as possible.

[0026] In addition, the temperature threshold is determined according to the set temperature in the conventional refrigeration operation mode. On this basis, if the temperature of the compartment is less than or equal to the temperature threshold, it can be indicated that the demand for cooling in the compartment has been basically met. After the temperature of the compartment is less than or equal to the temperature threshold, the refrigerator is controlled to switch from the large-volume storage refrigeration operation mode back to the conventional refrigeration operation mode. Since the demand for cooling of the newly added storage objects has been basically met, the conventional refrigeration operation mode is capable of maintaining the temperature of the refrigerator compartment at this time, such as supplementing the cooling consumption caused by opening and closing the refrigerator compartment door in daily life, and supplementing the cooling dissipated from the compartment itself to the outside of the refrigerator. In this case, the conventional refrigeration operation mode can also prepare for putting storage objects into the refrigerator compartment next time.

[0027] As analyzed above, when the volume of the items meets the judgment conditions for large-volume items, the refrigerator is controlled to switch from the conventional refrigeration operation mode to the large-volume storage refrigeration operation mode to meet the demand for cooling of the newly added stored items as much as possible; after the temperature of the compartment is less than or equal to the temperature threshold, the refrigerator is controlled to switch from the large-volume storage refrigeration operation mode back to the conventional refrigeration operation mode to match the cooling demand of the stored items in the refrigerator compartment with the refrigeration rate of the refrigerator to the compartment, thereby improving the preservation effect of the stored items in the refrigerator compartment.

[0042] Figure 1 It is a hardware schematic diagram of a refrigerator provided in an embodiment of the present application.

[0043] Combination Figure 1 As shown, the hardware relied on by the refrigerator refrigeration control method includes:

[0044] Refrigerator controller 11, compressor 12, fan 13, compartment valve 14 and damper 15;

[0045] Compartment A first volume recognition module A1, compartment A second volume recognition module A2, compartment A third volume recognition module A3, compartment A door status monitoring device A4 and compartment A temperature acquisition device A5;

[0046] The first volume recognition module B1 of compartment B, the second volume recognition module B2 of compartment B, the third volume recognition module B3 of compartment B, the door state detection device B4 of compartment B and the temperature acquisition device B5 of compartment B.

[0047] Among them, the first volume identification module A1 of compartment A, the second volume identification module A2 of compartment A and the third volume identification module A3 of compartment A are connected to the refrigerator controller 11. The three can transmit the detected data to the refrigerator controller 11, and the refrigerator controller 11 can calculate the volume of the stored objects in compartment A based on this, or the three can cooperate with each other to detect the remaining volume in compartment A.

[0048] The compartment A door status monitoring device A4 is connected to the refrigerator controller 11. When the door of compartment A is in an open state, the compartment A door status monitoring device A4 sends a signal to the refrigerator controller 11. When the door of compartment A is in a closed state, the compartment A door status monitoring device A4 sends another signal to the refrigerator controller 11.

[0049] The compartment A temperature acquisition device A4 can detect the temperature in the compartment A and send the detected data to the refrigerator controller 11.

[0050] The first volume recognition module B1 of compartment B, the second volume recognition module B2 of compartment B and the third volume recognition module B3 of compartment B are connected to the refrigerator controller 11. The three can transmit the detected data to the refrigerator controller 11, and the refrigerator controller 11 can calculate the volume of the stored objects in compartment B based on the data. Alternatively, the three can cooperate with each other to detect the remaining volume in compartment B.

[0051] The compartment B door status monitoring device B4 is connected to the refrigerator controller 11. When the door of compartment B is in an open state, the compartment B door status monitoring device B4 sends a signal to the refrigerator controller 11. When the door of compartment B is in a closed state, the compartment B door status monitoring device B4 sends another signal to the refrigerator controller 11.

[0052] The compartment B temperature acquisition device B4 can detect the temperature in the compartment B and send the detected data to the refrigerator controller 11.

[0053] The compressor 12 , the fan 13 , the chamber valve 14 and the damper 15 are all connected to the refrigerator controller 11 .

[0054] The compressor 12, the fan 13, the compartment valve 14 and the damper 15 can feed back their own states to the refrigerator controller 11, and the refrigerator controller 11 can also send control signals to the four to adjust their respective operating states.

[0055] In a single-system refrigerator, compartment A and compartment B may share a compressor 12 , a fan 13 and a compartment valve 14 , and compartment A and compartment B are provided with independent dampers 15 .

[0056] In a multi-system refrigerator, compartment A may correspond to a set of compressor 12 , fan 13 , compartment valve 14 and damper 15 ; compartment B may correspond to a set of compressor 12 , fan 13 , compartment valve 14 and damper 15 .

[0057] In the embodiment of the present application, compartment A may be a refrigerating compartment, and compartment B may be a freezing compartment;

[0058] Alternatively, compartment A may be a compartment in the cold storage room; compartment B may be another compartment in the cold storage room;

[0059] Alternatively, compartment A may be a compartment in a freezer compartment; and compartment B may be another compartment in a freezer compartment.

[0060] The conventional refrigeration operation mode and the large-volume storage refrigeration operation mode in the embodiments of the present application can both be implemented using existing control algorithms, such as a proportional-integral-differential (PID) control algorithm, a fuzzy control algorithm, and a neural network control algorithm. Both the conventional refrigeration operation mode and the large-volume storage refrigeration operation mode can adjust one or more of the solenoid valve, compressor, fan, and damper corresponding to the refrigerator compartment according to the actual temperature of the refrigerator compartment, and ultimately change the actual temperature of the refrigerator compartment to the set temperature corresponding to the conventional refrigeration operation mode.

[0061] The difference between the conventional refrigeration operation mode and the bulk storage refrigeration mode is that when the temperature difference between the actual temperature of the refrigerator compartment and the set temperature in the conventional refrigeration operation mode is the same, the refrigerator in the bulk storage refrigeration operation mode provides cold air to the refrigerator compartment faster and has a faster cooling rate for the refrigerator compartment than when the refrigerator is in the conventional refrigeration operation mode.

[0062] In some application scenarios, the set temperature corresponding to the conventional refrigeration operation mode is higher than the set temperature corresponding to the bulk storage refrigeration operation mode.

[0063] The storage objects in this application include but are not limited to food and its packaging, ingredients and its packaging, tableware and its packaging, etc.

[0064] Figure 2 The present invention provides a flow chart of a refrigerator refrigeration control method provided in an embodiment of the present invention. The refrigerator refrigeration control method can be executed by a refrigerator controller.

[0065] Combination Figure 2 As shown, the refrigeration control method of the refrigerator includes:

[0066] S201. When the refrigerator is in a normal refrigeration operation mode, the volume of items newly stored in the refrigerator compartment is obtained.

[0067] The existing infrared sensor can be used to sense the outline and volume of the stored items in the refrigerator compartment, thereby obtaining the volume of the items newly stored in the refrigerator compartment; or, the distance sensing device can be used to calculate the change in the free volume in the refrigerator compartment, and based on the change in the free volume, the volume of the items newly stored in the refrigerator compartment can be inferred.

[0068] Alternatively, you can also Figure 1 The volume of items newly stored in the compartment is obtained by the method shown in .

[0069] The above method for obtaining the volume of the newly stored items in the refrigerator compartment is only an exemplary description. In different scenarios, those skilled in the art can determine the volume detection method that suits the scenario based on experience to obtain the volume of the newly stored items in the refrigerator compartment.

[0070] S202: When the volume of the item meets the determination condition of a large-volume item, the refrigerator is controlled to switch from a normal refrigeration operation mode to a large-volume storage refrigeration operation mode.

[0071] The volume of the above-mentioned items meets the judgment condition of large-volume items, which means that based on the demand for cooling capacity of the newly added storage items in the refrigerator compartment and the adverse effect on the refrigeration effect of the refrigerator compartment, if the refrigerator is operated in a conventional refrigeration operation mode, the temperature in the refrigerator compartment cannot reach the set temperature corresponding to the conventional refrigeration operation mode, or the time taken for the temperature in the refrigerator compartment to reach the set temperature corresponding to the conventional refrigeration operation mode is greater than or equal to the time threshold.

[0072] Among them, the time threshold is positively correlated with the average time it takes for food to change from fresh to stale.

[0073] Generally, the time threshold can be set to be less than the average time it takes for food to go from fresh to stale. Of course, this is only an exemplary description. In actual applications, those skilled in the art can set a specific actual threshold based on the average time it takes for food to go from fresh to stale, so that after a large amount of food is put into the refrigerator, the refrigerator can cool the food in time to keep the food fresh.

[0074] The term "fresh" in the embodiments of the present application is consistent with the intuitive experience of food / ingredients in daily life: for example, if vegetables are wilted, they can be considered not fresh; if the taste of cooked food changes, it can be considered not fresh, and so on.

[0075] Optionally, the conditions for determining whether the volume of the item meets the criteria for determining whether the item is a large-volume item include one or more of the following:

[0076] First condition: the volume of the item is greater than or equal to the first volume threshold;

[0077] Second condition: the remaining space of the compartment is less than or equal to the second volume threshold;

[0078] The third condition: the ratio of the volume of the article to the volume of the compartment is greater than or equal to the first ratio threshold;

[0079] Fourth condition: the ratio of the volume of the article to the remaining volume of the compartment is greater than or equal to the second ratio threshold.

[0080] Among them, if the volume of the items is greater than or equal to the first volume threshold, it can be indicated that the demand for cooling capacity of the newly added storage items in the refrigerator compartment is likely to be higher.

[0081] The remaining space of the compartment is less than or equal to the second volume threshold, the ratio of the item volume to the compartment volume is greater than or equal to the first ratio threshold, and the ratio of the item volume to the remaining volume of the compartment is greater than or equal to the second ratio threshold, which can indicate that the newly added storage in the refrigerator compartment has had a significant adverse effect on the refrigeration effect inside the refrigerator compartment.

[0082] Those skilled in the art may obtain the first volume threshold, the second volume threshold, the first ratio threshold or the second ratio threshold according to the specific effects of the above conditions, based on experience or by experiment.

[0083] In the above steps, the cooling rate of the refrigerator compartment in the conventional cooling operation mode is lower than the cooling rate of the refrigerator compartment in the bulk storage cooling operation mode. After the refrigerator is switched from the conventional cooling operation mode to the bulk storage cooling operation mode, the cooling rate of the refrigerator compartment can be increased.

[0084] Optionally, controlling the refrigerator to switch from a conventional refrigeration operation mode to a bulk storage refrigeration operation mode includes: adjusting a solenoid valve and / or a compressor of the refrigerator compartment to increase a refrigeration rate of the refrigerator compartment.

[0085] Alternatively, controlling the refrigerator to switch from the normal refrigeration operation mode to the bulk storage refrigeration operation mode may include: adjusting a fan and / or a damper of the refrigerator compartment to increase the air flow rate in the refrigerator compartment.

[0086] Alternatively, controlling the refrigerator to switch from the conventional refrigeration operation mode to the bulk storage refrigeration operation mode may include: adjusting a solenoid valve and / or a compressor of the refrigerator compartment to increase a refrigeration rate for the refrigerator compartment; and adjusting a fan and / or a damper of the refrigerator compartment to increase an air flow rate in the refrigerator compartment.

[0087] The refrigerator may be a single-system refrigerator, that is, a compressor is used to cool multiple compartments of the refrigerator. In this case, the fan speed of a certain refrigerator compartment may be increased and / or the opening of the corresponding damper of the compartment may be increased to increase the air flow rate in the compartment; the control parameters related to another compartment (such as the damper opening, or the fan speed and damper opening) may remain unchanged.

[0088] The refrigerator may be a multi-system refrigerator, such as a dual-system refrigerator or a triple-system refrigerator. In this case, the opening of the solenoid valve and / or the compressor frequency of the refrigeration system corresponding to a certain compartment may be adjusted to adjust the refrigeration rate of the refrigerator compartment.

[0089] The embodiment of the present application does not specifically limit the adjustment method of the solenoid valve and / or compressor of the refrigerator compartment. Those skilled in the art can make adjustments based on experience to achieve the effect of improving the refrigeration rate of the refrigerator compartment; the embodiment of the present application does not specifically limit the adjustment method of the fan and / or damper of the refrigerator compartment. Those skilled in the art can make adjustments based on experience to achieve the effect of improving the refrigeration rate of the refrigerator compartment.

[0090] S203: After the temperature of the compartment is less than or equal to the temperature threshold, the refrigerator is controlled to switch from the bulk storage refrigeration operation mode back to the normal refrigeration operation mode.

[0091] The temperature threshold is determined according to the set temperature in the conventional refrigeration operation mode. The temperature threshold may be less than or equal to the set temperature corresponding to the conventional refrigeration operation mode, or the temperature threshold may be greater than the set temperature corresponding to the conventional refrigeration operation mode.

[0092] Optionally, controlling the refrigerator to switch from the bulk storage refrigeration operation mode back to the normal refrigeration operation mode includes: adjusting a solenoid valve and / or a compressor of the refrigerator compartment to reduce a refrigeration rate for the refrigerator compartment.

[0093] Alternatively, controlling the refrigerator to switch from the bulk storage refrigeration operation mode back to the normal refrigeration operation mode may include: adjusting a fan and / or a damper of the refrigerator compartment to reduce the air flow rate in the refrigerator compartment.

[0094] Alternatively, controlling the refrigerator to switch from the bulk storage refrigeration operation mode back to the normal refrigeration operation mode may include: adjusting a solenoid valve and / or a compressor of the refrigerator compartment to reduce a refrigeration rate for the refrigerator compartment; and adjusting a fan and / or a damper of the refrigerator compartment to reduce an air flow rate in the refrigerator compartment.

[0095] After newly added storage items are added to the refrigerator compartment, if the volume of the newly added storage items meets the judgment conditions for large-volume items, it means that the newly added storage items have caused a significant increase in the demand for cooling capacity in the refrigerator compartment, and / or, it means that the newly added storage items have caused a significant decrease in the ability of the refrigerator to provide cooling capacity to the compartment. At this time, the refrigerator is controlled to switch from the conventional refrigeration operation mode to the large-storage refrigeration operation mode to increase the refrigeration rate for the compartment. A higher refrigeration rate for the compartment means a higher rate of providing cooling capacity to the compartment, so as to meet the cooling capacity demand of the newly added storage items as much as possible.

[0096] In addition, the temperature threshold is determined according to the set temperature in the conventional refrigeration operation mode. On this basis, if the temperature of the compartment is less than or equal to the temperature threshold, it can be indicated that the demand for cooling in the compartment has been basically met. After the temperature of the compartment is less than or equal to the temperature threshold, the refrigerator is controlled to switch from the large-volume storage refrigeration operation mode back to the conventional refrigeration operation mode. Since the demand for cooling of the newly added storage objects has been basically met, the conventional refrigeration operation mode is capable of maintaining the temperature of the refrigerator compartment at this time, such as supplementing the cooling consumption caused by opening and closing the refrigerator compartment door in daily life, and supplementing the cooling dissipated from the compartment itself to the outside of the refrigerator. In this case, the conventional refrigeration operation mode can also prepare for putting storage objects into the refrigerator compartment next time.

[0097] As analyzed above, when the volume of the items meets the judgment conditions for large-volume items, the refrigerator is controlled to switch from the conventional refrigeration operation mode to the large-volume storage refrigeration operation mode to meet the demand for cooling capacity of the newly added stored items as much as possible; after the temperature of the compartment is less than or equal to the temperature threshold, the refrigerator is controlled to switch from the large-volume storage refrigeration operation mode back to the conventional refrigeration operation mode to match the cooling capacity demand of the stored items in the refrigerator compartment with the refrigeration rate of the refrigerator for the compartment, so as to prevent the temperature in the compartment from being too low or too high for a long time, thereby improving the preservation effect of the stored items in the refrigerator compartment.

[0098] In the embodiment of the present application, switching the refrigeration operation mode of the refrigerator is used as the core technical solution. In this way, in the process of determining the first volume threshold, the second volume threshold, the first ratio threshold and the second ratio threshold, even if the specific values ​​determined by different technicians are different, when the volume of the object meets the judgment condition of the large-volume object, the refrigerator is controlled to switch from the conventional refrigeration operation mode to the large-volume storage refrigeration operation mode; after the temperature of the compartment is less than or equal to the temperature threshold, the refrigerator is controlled to switch from the large-volume storage refrigeration operation mode back to the conventional refrigeration operation mode, which can also provide a relatively sufficient refrigeration rate for the refrigerator compartment, so as to achieve a match between the demand for coldness of the newly stored objects and the coldness that can be provided by the refrigerator compartment, so as not to make the indoor temperature of the refrigerator compartment too low or too high for a long time, thereby improving the preservation effect of the stored objects in the refrigerator compartment.

[0099] In the embodiment of the present application, the set temperature in the conventional refrigeration operation mode is relatively clear, and the speed of providing coldness to the refrigerator in the large-volume storage refrigeration operation mode is relatively vague. In this case, even if different technicians adopt different specific control schemes for the conventional refrigeration operation mode and the specific control schemes for the large-volume storage refrigeration operation mode, when the volume of the items meets the judgment conditions of large-volume items, the refrigerator is controlled to switch from the conventional refrigeration operation mode to the large-volume storage refrigeration operation mode; after the temperature of the compartment is less than or equal to the temperature threshold, the refrigerator is controlled to switch from the large-volume storage refrigeration operation mode back to the conventional refrigeration operation mode, which can also provide a relatively sufficient refrigeration rate for the refrigerator compartment, so as to match the demand for coldness of the newly stored items with the coldness that the refrigerator compartment can provide, so as not to make the temperature in the refrigerator compartment too low or too high for a long time, and improve the preservation effect of the stored items in the refrigerator compartment.

[0100] The following is an exemplary description of the process of obtaining the volume of the items newly stored in the refrigerator compartment.

[0101] In a possible implementation, obtaining the volume of the newly stored items in the refrigerator compartment includes: obtaining the volume of the newly stored items in the refrigerator compartment during a process of opening and closing the door of the refrigerator compartment, so as to adapt to the daily use habits of the refrigerator.

[0102] Optionally, during a process of opening and closing the refrigerator door, obtaining the volume of items newly stored in the refrigerator compartment includes: obtaining a first volume of items stored in the refrigerator compartment when the compartment door is opened; obtaining a second volume of items stored in the refrigerator compartment when the compartment door is closed; and determining the volume of items newly stored according to a first volume difference between the second volume and the first volume.

[0103] Normally, the first volume difference can be directly used as the volume of the newly added storage items; in the case that the newly added storage items will expand in volume, the difference between the first volume difference and a correction value can be used as the volume of the newly added storage items, and the correction value is positively correlated with the change in volume expansion of the newly added storage items; or, in the case that the newly added storage will shrink in volume, the sum of the first volume difference and another correction value can be used as the volume of the newly added storage items, and the other correction value is positively correlated with the change in volume shrinkage of the newly added storage.

[0104] In a possible implementation, obtaining the volume of newly stored items in the refrigerator compartment may include: obtaining the volume of newly stored items in the refrigerator compartment within a set time period before the refrigerator compartment door is closed. This is applicable to the scenario where the refrigerator compartment door is opened and closed multiple times in a short period of time and newly stored items are stored in the refrigerator compartment.

[0105] Optionally, obtaining the volume of items newly stored in the refrigerator compartment within a set time period before the refrigerator compartment door is closed includes: obtaining a third volume of items stored in the refrigerator compartment at a first moment when the compartment door is closed; obtaining a fourth volume of items stored in the refrigerator compartment at a second moment; and determining the volume of items newly stored according to a second volume difference between the third volume and the fourth volume; wherein the second moment is before the first moment, and a time interval between the first moment and the second moment is the set time period.

[0106] The set time can be used to indicate the average time that users use the refrigerator in daily life scenarios. For example, the set time can indicate the average time that users spend cleaning up after a meal; or the set time can indicate the average time that users spend putting vegetables, meat, and other items into the refrigerator after shopping.

[0107] Typically, the set time may be slightly longer than the average time that users use a refrigerator in real life scenarios. For example, the set time may be 3 minutes, 5 minutes, or 7 minutes longer than the average time that users use a refrigerator in real life scenarios.

[0108] The use of the above-mentioned set time length can make the refrigeration control method of the refrigerator more suitable for the user's living habits.

[0109] Alternatively, in the default state, the refrigerator is in a normal refrigeration operation mode, and the set duration can be used to indicate the average time required for the temperature of the stored items to reach the set temperature corresponding to the normal refrigeration operation mode from the initial temperature after the stored items are placed in the refrigerator.

[0110] Normally, the set duration is made less than or equal to the above-mentioned average required duration so that the refrigerator can be switched from the conventional refrigeration operation mode to the large-volume storage refrigeration operation mode in time, so as to increase the cooling capacity for the stored items in the refrigerator in time and enable the stored items to be cooled in time, thereby ensuring the freshness preservation effect of the refrigerator.

[0111] During the set time period, the refrigerator compartment door may be opened and closed one or more times.

[0112] For example, if the refrigerator compartment door is in a closed state at the second moment, the volume of the stored objects in the refrigerator compartment detected at the second moment may be directly used as the fourth volume;

[0113] If the refrigerator compartment door is in an open state at the second moment, the volume of the stored objects in the refrigerator compartment detected at the second moment may be directly used as the fourth volume, or the volume of the stored objects in the refrigerator compartment detected at a moment before the second moment and closest to the second moment when the refrigerator compartment door is in a closed state may be used as the fourth volume.

The refrigerator refrigeration control method can be executed by a refrigerator controller. In this embodiment, the refrigerator compartment includes a refrigerating compartment and a freezing compartment as an example to illustrate the refrigerator refrigeration control method.

When the volume of the first item meets the judgment condition for a large-volume item, the refrigeration mode of the refrigerator compartment is controlled to switch from the first conventional refrigeration operation mode to the first large-volume storage refrigeration operation mode; when the volume of the second item meets the judgment condition for a large-volume item, the refrigeration mode corresponding to the freezer compartment is controlled to switch from the second conventional refrigeration operation mode to the second large-volume storage refrigeration operation mode.

[0119] S303. When the first actual temperature in the cold storage chamber is less than or equal to the first temperature threshold, the refrigeration mode of the cold storage chamber is controlled to switch back from the first large-volume storage refrigeration operation mode to the first normal refrigeration operation mode; when the second actual temperature in the freezer chamber is less than or equal to the second temperature threshold, the refrigeration mode of the freezer chamber is controlled to switch back from the second large-volume storage refrigeration operation mode to the second normal refrigeration operation mode.

[0120] Among them, the cooling rate of the refrigerator for the cold storage chamber in the first conventional refrigeration operation mode is lower than the cooling rate of the refrigerator for the cold storage chamber in the first large-scale storage refrigeration operation mode, and the first temperature threshold is determined according to the set temperature in the first conventional refrigeration operation mode; the cooling rate of the refrigerator for the freezer chamber in the second conventional refrigeration operation mode is lower than the cooling rate of the refrigerator for the freezer chamber in the second large-scale storage refrigeration operation mode, and the second temperature threshold is determined according to the set temperature in the second conventional refrigeration operation mode.

[0121] In the above-mentioned embodiment, the cooling modes in the refrigerating chamber and the freezing chamber are independent of each other.

[0122] A refrigerator, which consists of a refrigerator and a freezer, can operate in four modes:

[0123] The first mode: the refrigerator compartment is in the first conventional refrigeration operation mode, and the freezer compartment is in the second conventional refrigeration operation mode;

[0124] The second mode: the refrigerator compartment is in the first bulk storage refrigeration operation mode, and the freezer compartment is in the second conventional refrigeration operation mode;
