[0002] This application claims priority to Chinese patent application No. 202410814055X, filed on June 21, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] Some embodiments of this application relate to refrigerator technology. More specifically, it relates to a refrigerator and its refrigeration control method and operation control method. Background Technology

[0004] To enhance the versatility of refrigerator functions, refrigerators with this technology, in addition to having a freezer compartment and a refrigerator compartment, also have a variable temperature compartment, allowing users to set the temperature of the variable temperature compartment to be between that of the freezer and refrigerator compartments according to their actual needs.

[0005] The refrigeration system of a refrigerator mainly consists of a compressor and an evaporator. Since the variable temperature compartment is an auxiliary function, it usually shares the same evaporator with the freezer compartment for refrigeration. This means that when the variable temperature compartment needs to be refrigerated, the freezer compartment, which is connected to the variable temperature compartment and the refrigeration system, is also circulated with cold air. This causes the low temperature in the freezer compartment to be further increased, and the compressor's running time to be longer. Furthermore, because the temperature of the variable temperature compartment can be easily adjusted according to the user's settings, the compressor often has to increase its operating rate to reach the temperature of the variable temperature compartment, thus increasing power consumption.

[0070] To make some embodiments of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments.

[0071] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0072] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a series of components is not necessarily limited to those that are explicitly listed, but may include other components that are not explicitly listed or that are inherent to such product or device.

[0073] In addition to the freezer and refrigerator compartments, refrigerators using this technology also feature a variable-temperature compartment. This allows users to set the temperature of the variable-temperature compartment to a level between the freezer and refrigerator compartments, depending on their needs. Because the variable-temperature compartment is an auxiliary function, it is typically located between the refrigerator and freezer compartments and has limited space. Therefore, it does not have its own dedicated evaporator; instead, it usually shares the same evaporator with the freezer compartment to meet freezing requirements.

[0074] When the temperature of the variable temperature compartment is set low, the temperature of the freezer compartment drops faster because the airflow from the evaporator to the freezer compartment is shorter. The airflow of the variable temperature compartment is longer, so the temperature of the variable temperature compartment drops more slowly. This results in the temperature of the freezer compartment being drawn deeper, the compressor running time becoming longer, and because the temperature of the variable temperature compartment can be easily adjusted according to the user's settings, the compressor often has to increase its operating rate to meet the temperature requirements of the variable temperature compartment, thus increasing power consumption.

[0075] In view of this, some embodiments of the refrigerator provided in this application do not start the compressor when there is a cooling demand in the variable temperature compartment. Instead, the ventilation component 70 between the variable temperature compartment and the freezer compartment is activated. The cooling capacity of the freezer compartment is first drawn to the variable temperature compartment for cooling by utilizing the temperature difference between the freezer compartment and the variable temperature compartment. When the start-up temperature of the freezer compartment is reached, or when the temperature of the freezer compartment is similar to that of the variable temperature compartment and does not meet the temperature demand of either compartment, the compressor is then activated to cool the freezer compartment and the variable temperature compartment simultaneously. This reduces the energy consumption of excessive cooling in the freezer compartment and reduces the compressor start-up rate, aiming to solve the above-mentioned problems in the related technology.

[0076] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0077] Figure 1 is a schematic diagram of a refrigerator in some embodiments of this application; Figure 2 is a cross-sectional view AA in Figure 1; Figure 3 is a schematic diagram of the internal structure of Figure 1 after the door is removed. When the user faces the refrigerator door, the width direction of the refrigerator, i.e., the left-right direction, corresponds to the X-axis direction in the figures; the depth direction of the refrigerator, i.e., the depth direction of the compartments, i.e., the front-back direction, corresponds to the Y-axis direction in the figures; and the height direction of the refrigerator, i.e., the up-down direction, corresponds to the Z-axis direction in the figures. The width of the refrigerator door is the dimension along the X-axis when the door is closed, the thickness of the door is the dimension along the Y-axis when the door is closed, and the height of the door is the dimension along the Z-axis.

[0078] As shown in Figures 1, 2, and 3, some embodiments of the refrigerator of this application include a door 10 and a cabinet 20. The cabinet 20 includes a storage compartment with a front opening for storing food and other items. The door 10 is installed on the front of the storage compartment and is used to open or close the storage compartment. There may be one storage compartment; or there may be multiple storage compartments, which can be arranged at intervals along the height and / or width of the refrigerator. For example, the storage compartments can be divided into freezer compartments, refrigerator compartments, and variable temperature compartments according to different storage temperatures. For another example, shelves can be provided in the storage compartment to increase the placement space for items. Furthermore, drawers can also be provided in the storage compartment, which can be pulled out relative to the depth of the refrigerator for convenient categorized storage and retrieval of items.

[0079] In some embodiments, the door 10 is rotatably mounted on the housing 20 to open or close the storage compartments. Exemplarily, the door 10 is rotatably connected to the housing 20 via a hinge assembly. When multiple storage compartments are provided, there may be one door 10, with multiple storage compartments sharing one door 10; alternatively, there may be multiple doors 10, each corresponding to a different storage compartment.

[0080] In some embodiments, at least one shelf is provided on the door 10, with the shelf opening upwards for storing items. In some embodiments of this application, a shelf is provided on the door 10 corresponding to the refrigerated compartment. Multiple shelves are arranged at intervals along the height direction of the door 10 to further increase the storage space for items. In some embodiments, multiple shelves are arranged at non-uniform intervals along the height direction of the door 10. The storage height H of the shelves is different. Wherein, the storage height H of the shelf is the height interval between the support plane of the shelf and the bottom surface of the shelf above it, and the storage height H of the top shelf is the interval between the shelf and the top seal of the door 10. In this way, while increasing the storage space for items, it can accommodate items of different heights.

[0081] In some embodiments, the door 10 can be designed as a multi-layered nested structure with different functional areas. For example, the outermost layer is a storage door, and the inner layers can have small freezer compartments or variable temperature compartment doors. This modular design allows users to flexibly adjust the refrigeration space according to their storage needs. Door structures compatible with different refrigeration requirements can be configured. For example, the lower half of the door 10 can be designed with built-in refrigerator drawers, while the upper half retains a shelf design. This design effectively increases storage flexibility.

[0082] Referring to FIG2, the refrigerator in some embodiments of this application further includes a compressor 30. The compressor 30 is used to lower the temperature of the refrigerator's storage compartment, enabling the storage compartment to perform refrigeration or freezing tasks according to a preset temperature, thereby extending the storage time of items placed in the storage compartment. In some embodiments, the storage compartment includes a refrigerator compartment 211, a variable temperature compartment 212, and a freezer compartment 213. Referring to FIGS. 2 and 3, the refrigerator compartment 211, the variable temperature compartment 212, and the freezer compartment 213 are arranged sequentially from top to bottom. In some embodiments, temperature sensors for detecting temperature changes in the storage compartment are also provided in the storage compartment. The temperature sensors are located in different storage compartments, including a second temperature sensor 41 located in the refrigerator compartment 211, a third temperature sensor 42 located in the variable temperature compartment 212, and a first temperature sensor 43 located in the freezer compartment 213. In some embodiments, the first temperature sensor 43 can be called a freezer compartment temperature sensor, the second temperature sensor 41 can be called a refrigerator compartment temperature sensor, and the third temperature sensor 42 can be called a variable temperature compartment temperature sensor.

[0083] Referring again to Figure 2, some embodiments of the refrigerator in this application further include a humidity sensor 50. The humidity sensor 50 is used to detect the humidity of the outside air. The humidity sensor 50 can be disposed on the top of the cabinet 20 near the refrigerator door 10 to achieve relatively accurate detection of the air humidity when entering the storage compartment through the door 10. It is understood that the humidity sensor 50 can also be disposed on the side of the cabinet 20, or the bottom surface of the cabinet 20, or even the back of the cabinet 20, or on the door 10, as long as it can come into contact with the outside air.

[0084] Referring to Figure 3, in some embodiments, an ice-making chamber 214 may also be provided inside the refrigerator compartment 211. The ice-making chamber 214 is used to make ice cubes and cold drinks. The refrigerator compartment 211 has an independent refrigerator compartment evaporator 31, which can realize independent cooling of the refrigerator compartment 211 and an independent supply and return air system, avoiding odor transfer with other compartments, and also providing a relatively short cooling path for the ice-making chamber 214. Continuing to refer to Figure 3, the refrigerator compartment 211 adopts a front-outlet cooling method. The refrigerator air supply vent 331 is located above the refrigerator compartment 211, and the refrigerator return air vent 332 is located below the refrigerator compartment 211. The low-temperature air blown out by the refrigerator air supply vent 331 mixes with the air inside the refrigerator compartment 211, quickly lowering the temperature of the refrigerator compartment 211, thereby achieving cooling of the refrigerator compartment 211. To maintain a refrigerated temperature within the cold storage compartment 211, the outlet air temperature of the cold storage compartment 211 is typically low (generally ≤-15°C), and the temperature near the refrigerated air vent 331 is even lower. The ice-making compartment 214 can be located near the upper refrigerated air vent 331, but the water supply system should be installed away from this location. In some embodiments, the evaporator 31 of the cold storage compartment can be referred to as a refrigerated evaporator.

[0085] Figure 4 is a schematic diagram of the internal structure of the refrigerator compartment after removing the front cover of Figure 3; Figure 5 is a schematic diagram of the internal structure of the back panel of the refrigerator compartment. Referring to Figures 4 and 5, the refrigerator compartment 211 includes a refrigerator compartment evaporator 31 and a refrigerator fan 32. The refrigerator fan 32 includes a fan and is located above the refrigerator compartment evaporator 31. It is used to transport the cooled air after the refrigerator compartment evaporator 31 is cooled by the fan from the refrigerator air supply channel 333 connected to the refrigerator air supply port 331 above into the refrigerator compartment 211. Meanwhile, the hot air in the refrigerator compartment 211 is transported from the refrigerator return air channel 334 connected to the refrigerator return air port 331 below to the refrigerator compartment evaporator 31 for the next refrigeration cycle in the refrigerator compartment 211. The refrigerator compartment 211 is also equipped with a fourth temperature sensor 44, which is located near the evaporator 31 of the refrigerator compartment, for example, at the top. This fourth temperature sensor 44 senses the defrosting temperature of the evaporator 31, allowing it to operate efficiently under temperature indication. Since the evaporator 31 dries hot air while cooling, the output cold air has a low moisture content and is less prone to condensation. Therefore, by increasing the fan speed, the humidity inside the refrigerator compartment 211 can be reduced. Thus, when the ambient humidity is high, adjusting the fan speed can reduce the humidity of the air entering the refrigerator compartment 211 from the outside. In some embodiments, the fourth temperature sensor 44 can be referred to as the refrigerator compartment evaporator temperature sensor.

[0086] Figure 6 is a schematic diagram of the external structure of the back panel of the cold storage compartment. Referring to Figure 6, the evaporator 31 and the refrigeration fan 32 of the cold storage compartment are fixed to the front cover 22 of the cold storage compartment and covered by the rear cover 23 of the cold storage compartment to provide physical protection for the evaporator 31 and the refrigeration fan 32. A refrigeration return air vent 332 is provided below the rear cover 23 of the cold storage compartment, and a refrigeration return air channel 334 is provided below the front cover 22 of the cold storage compartment. This allows the air in the cold storage compartment 211 to enter the interior of the rear cover 23 of the cold storage compartment through the refrigeration return air channel 334 and the refrigeration return air vent 332 in sequence. After exchanging heat with the evaporator 31 inside, the air flows into the refrigeration fan 32 above and is output to the cold storage compartment 211 by the fan vortex action of the refrigeration fan 32, completing the cold air circulation. Since there are no auxiliary devices in the above-mentioned refrigerated return air path, the entire refrigerated air circulation relies on the air flow driven by the fan of the refrigerated fan 32. The evaporator 31 of the refrigerated compartment can reduce the moisture in the air during the condensation process, and the evaporator 31 of the refrigerated compartment can still maintain the refrigeration function for a period of time after the compressor 30 is turned off.

[0087] In some embodiments, by adding an air distribution device to the refrigerated return air vent 332, airflow can be made more uniform, preventing some areas from becoming too cold or experiencing temperature instability, thereby improving the efficiency of cold air circulation and the temperature stability of the refrigerated compartment. A humidity sensor is installed in the refrigerated compartment to automatically adjust the humidity level according to the food storage requirements. The humidity control device can work in conjunction with the evaporator in the refrigerated compartment via a miniature humidifier or dehumidifier to maintain the humidity within the refrigerated compartment within a suitable range, preventing food from drying out and reducing frost formation.

[0088] In some embodiments, the end of a second temperature sensor 41 is also provided on the front cover 22 of the refrigerator compartment, and the front end of the second temperature sensor 41 extends into the refrigerator compartment 211 to avoid the temperature of the front cover 22 itself and the air behind the front cover 22 affecting the actual temperature inside the compartment. At the same time, it can also prevent the terminal wires from being run inside the refrigerator compartment 211, which can improve the cleanliness and aesthetics of the refrigerator compartment 211 and also protect the wires.

[0089] Referring to Figure 5, a sealing rib 335 is also provided at the refrigerated return air duct 334. The sealing rib 335 is arranged along the X-axis direction to block the hot air that returns after circulation. A return air gap 336 is provided below the refrigerated compartment evaporator 31 so that the refrigerated return air can be concentrated and input into the refrigerated compartment evaporator 31 according to the opening path of the refrigerated return air duct 334 and the return air gap 336, thereby improving the refrigeration efficiency.

[0090] Figure 7 is a schematic diagram of the front structure of the back panel of the variable temperature compartment and the freezer compartment. Referring to Figures 2 and 6, the variable temperature compartment 212 includes a front cover 24. Referring to Figures 6 and 7, the front cover 24 of the variable temperature compartment is equipped with a third temperature sensor 42, a return air vent 341, and an air supply vent 342. The third temperature sensor 42 is located near the return air vent 341 to avoid reducing the accuracy of the actual temperature detection inside the variable temperature compartment 212 due to the low temperature of the cold air output from the air supply vent 342.

[0091] Referring again to Figures 2 and 7, the freezer compartment 213 includes a front cover 25, on which a first temperature sensor 43, a return air vent 351, and an air supply vent 352 are disposed. In some embodiments, multiple air supply vents 352 are provided to increase the output of cold air. For example, four air supply vents 352 are provided, distributed near the four corners of the front cover 25 to improve cooling efficiency. The first temperature sensor 43 is located in the center to avoid the cold air output from the air supply vents 352 being too cold and reducing the accuracy of the actual temperature detection inside the freezer compartment 213. Furthermore, since there are multiple air supply vents 352, the temperature inside the freezer compartment 213 can be quickly reduced, and the temperature difference will not be too large. Therefore, it is not necessary to place the first temperature sensor 43 near the return air vent 351.

[0092] In some embodiments, the freezer compartment air outlet 352 is angled upwards, while the freezer compartment return air outlet 351 is an arc-shaped plate with an angled rearward opening. This arc-shaped plate is positioned below the freezer compartment 213 so that after cold air is blown out from the freezer compartment air outlet 352, it circulates downwards within the freezer compartment 213 to the bottom arc-shaped plate. The arc shape faces inwards towards the compressor 30, allowing the circulated air to quickly enter the compressor 30, reducing the airflow distance, minimizing low-temperature refrigeration energy loss, and improving the cooling effect. Furthermore, the arc-shaped plate facilitates air return and also provides space for the compressor 30.

[0093] In some embodiments, in addition to providing multiple air outlets 352 on the front cover 25 of the freezer compartment, multiple vertical or horizontal air outlet layers can also be provided to help air cover more areas when flowing within the freezer compartment, improving cooling efficiency. Layered air outlets allow cold air to be delivered directly to deeper areas, avoiding cold air waste. An auxiliary cold air circulation fan can be added to the bottom of the freezer compartment to enhance airflow. By combining the freezer fan and air outlet system, a stronger circulation of cold air is achieved within the freezer compartment, quickly delivering cold air to corners, especially hard-to-cool areas when storing large items, thus improving cooling efficiency.

[0094] Figure 8 is a schematic diagram of the rear structure of the back panel of the variable temperature compartment and the freezer compartment; Figure 9 is a schematic diagram of the internal structure of the back panel of the variable temperature compartment and the freezer compartment. Referring to Figures 8 and 9, the rear cover 26 of the freezer compartment completely covers the rear of the variable temperature compartment 212 and the freezer compartment 213. A freezer air duct cover isolation piece 27 is provided between the front cover 25 and the rear cover 26 of the freezer compartment. The freezer air duct cover isolation piece 27 is used to isolate the external environment from the freezer compartment 213, and a freezer air duct is formed through the freezer air duct cover isolation piece 27 so that cold air flows to the air outlets 352 of multiple freezer compartments. A refrigeration fan 36 is also installed inside the refrigeration duct. The refrigeration fan 36 includes a fan. The air outlet side of the refrigeration fan 36 is connected to the air outlet 352 of the refrigeration compartment, and the air receiving side of the fan 36 is connected to the refrigeration evaporator (which has a similar function and structure to the evaporator in the refrigerator compartment and is not shown in the figure). This allows the air cooled by the refrigeration evaporator to be drawn into the refrigeration duct and discharged into the refrigeration compartment 213 through the air outlet 352, thus realizing the air cooling circulation process in the refrigeration compartment 213. In some embodiments, the refrigeration duct cover plate separator 27 can be a refrigeration duct cover plate foam.

[0095] Referring again to Figure 8, in some embodiments, an electric damper 37 is also provided in the refrigeration air duct. The electric damper 37 is used to connect the refrigeration air duct and the variable temperature compartment 212, thereby transporting cold air from the refrigeration air duct to the variable temperature compartment 212. Since the temperature setting of the variable temperature compartment 212 cannot be lower than the temperature setting of the refrigeration compartment 213, the refrigeration air duct can be used directly to cool the variable temperature compartment 212 while maintaining the low temperature state of the refrigeration compartment 213. This allows the compressor 30 to reduce the temperature of both compartments at once, improving the utilization rate of the compressor 30 and reducing the number of times the compressor 30 is started. Similar to the refrigeration return air path, there are no auxiliary devices in the above-mentioned refrigeration return air path. The entire refrigeration air circulation relies on the air flow driven by the fan of the refrigeration fan 36. The refrigeration evaporator can reduce the moisture in the air during the condensation process, and the refrigeration evaporator can still maintain the refrigeration function for a period of time after the compressor 30 is turned off. In some embodiments, the electric damper 37 can be called the variable temperature compartment electric damper.

[0096] In some embodiments, a refrigerated air duct may be provided between the ice-making chamber 214 and the cold storage chamber 211. The end or interior of the refrigerated air duct is provided with a cold storage chamber electric damper, the structure of which can be referred to as the electric damper 37 shown in FIG8. This enables the ice-making chamber 214 to start the refrigeration system when making ice, while providing a portion of the cold source to the cold storage chamber 211. This allows the refrigeration system to reduce the temperature of both the ice-making chamber 214 and the cold storage chamber 211 to the temperature required for shutdown with a single start of the compressor 30, thereby reducing the number of times the compressor 30 is started due to the cooling needs of the cold storage chamber 211 and thus extending the service life of the compressor 30.

[0097] In some embodiments, when the temperature of the refrigerator compartment 211 rises to the start point of the refrigeration system, the compressor 30 is not started immediately. Instead, the electric damper of the refrigerator compartment is opened first to allow cold air from the ice-making compartment 214 to flow into the refrigerator compartment 211, thereby cooling the refrigerator compartment 211. Compared to directly introducing cold air from the freezer compartment 213 or the variable temperature compartment 212, the airflow path of the ice-making compartment 214 is shorter. Furthermore, since the temperature of the ice-making compartment 214, located in the refrigerator compartment 211, is typically set at or slightly below zero degrees Celsius, while the temperature of the refrigerator compartment is typically around 4 degrees Celsius, the temperature difference between the two is not significant. Therefore, while assisting in cooling the refrigerator compartment 211, it also prevents the entry of excessively cold air into the refrigerator compartment 211, which could cause condensation or other adverse effects.

[0098] It should be noted that the compressor 30, the refrigerator compartment evaporator 31, the refrigerator fan 32, the freezer fan 36, and the freezer evaporator (not shown in the figure) in the above embodiments together constitute the refrigerator's refrigeration system. The refrigeration system can be used to lower the temperature of the target compartment inside the refrigerator. The following description uses the refrigerator's control device 60 as the executing entity to illustrate how the refrigerator performs refrigeration control. Some of the following embodiments can be combined with each other; similar or identical concepts or processes may not be described again in some embodiments.

[0099] In some embodiments, as shown in FIG12, the control device 60 is connected to the refrigeration system 13, the ventilation assembly 70, the humidity sensor 50, the first temperature sensor 43, the second temperature sensor 41, the third temperature sensor 42, and the fourth temperature sensor 44, respectively.

[0100] Figure 10 is a schematic flowchart of a refrigerator cooling control method provided in some embodiments of this application. As shown in Figure 10, the method includes the following steps:

[0101] S101. When the refrigeration system is turned off and the temperature of the variable temperature chamber is higher than the preset ventilation opening temperature, the ventilation component 70 is turned on so that the air in the freezer chamber flows to the variable temperature chamber.

[0102] The ventilation start-up temperature is used to indicate the ventilation start-up temperature of the variable-temperature chamber. That is, when the temperature inside the variable-temperature chamber is detected to be higher than the ventilation start-up temperature, it indicates that the variable-temperature chamber does not meet the preset temperature conditions and requires cooling. Because temperature detection has a certain fluctuation range, and due to unavoidable spatial limitations in the sensor's placement, the detected temperature may not represent the average temperature inside the target chamber in real time. Therefore, it cannot accurately reflect the precise time point of the overall temperature change in the target chamber. It is necessary to set a range for the temperatures corresponding to the start and stop of the cooling system. Within a certain temperature range, the temperature conditions of the target chamber are met; outside this range, further control processing is required.

[0103] Therefore, the ventilation opening temperature setting is based on the user's preset temperature for the variable temperature room. For example, if the user's preset temperature for the variable temperature room is -18 degrees Celsius, the ventilation opening temperature can be -16 degrees Celsius. If the temperature exceeds -16 degrees Celsius, the control device 60 will need to perform certain operations to cool the variable temperature room.

[0104] In some embodiments, the ventilation assembly 70 may only include a duct connecting the variable temperature chamber and the freezer chamber, or it may include both a duct and a fan. The fan is installed inside the ventilation duct and can draw air from the freezer chamber to the variable temperature chamber. In this case, the connecting duct and the fan together constitute the ventilation assembly 70.

[0105] In some embodiments, when the refrigerator's refrigeration system is turned off, in order to maintain the variable temperature compartment and the freezer compartment within their respective independent temperature ranges, for example, the variable temperature compartment and the freezer compartment are respectively within a range of fluctuation of 2 degrees above and below the set temperature, the passage connecting the variable temperature compartment and the freezer compartment is closed, which can play a certain temperature isolation role and help maintain their respective temperature ranges. Therefore, the ventilation component 70 installed on the passage does not need to be turned on and is in a closed state.

[0106] When the temperature of the variable temperature chamber is higher than the preset ventilation start temperature, since the variable temperature chamber is connected to the freezer chamber, the low temperature of the freezer chamber can be used to cool the variable temperature chamber so that it reaches its set temperature requirement. This avoids starting the compressor in the refrigeration system, thereby reducing the compressor's operating rate, extending the compressor's service life, and reducing the compressor's power consumption.

[0107] S102. When the temperature of the variable temperature chamber reaches the preset ventilation shutdown temperature, the ventilation component 70 is shut off.

[0108] The ventilation shut-off temperature is used to indicate the ventilation shut-off temperature of the variable-temperature room. In some embodiments, the ventilation shut-off temperature is set in the same way as the ventilation opening temperature in the previous step, except that the ventilation shut-off temperature is lower than the user-preset temperature of the variable-temperature room. For example, if the user-preset temperature of the variable-temperature room is -18 degrees Celsius, its ventilation opening temperature can be -20 degrees Celsius. When it exceeds -20 degrees Celsius, the control device 60 needs to perform certain operations to isolate the variable-temperature room from the cold source.

[0109] The operation of shutting off the ventilation component 70 when the preset ventilation shut-off temperature is reached can prevent the items stored in the target compartment from being affected by exceeding the user's ideal temperature range. It can also prevent the waste of freezing resources, balance the distribution of cold source between the compartments in the refrigerator, and make the freezing resources achieve optimal utilization, thereby reducing the compressor's operating rate in the refrigeration system.

[0110] In some embodiments, based on the above embodiments, the method may further include the following steps:

[0111] S103. If the temperature of the variable temperature room fails to reach the preset ventilation shutdown temperature after a first period of time, the refrigeration system is turned on.

[0112] In some embodiments, the refrigerator presets the temperature of the freezer compartment and the temperature of the variable temperature compartment to be the same. When the temperature of the variable temperature compartment does not meet the usage requirements, the freezer compartment may still be within the freezing range because it stores a lot of frozen items, which will continuously emit cold energy.

[0113] In some embodiments, machine learning or artificial intelligence algorithms are introduced to predict temperature change trends in the variable-temperature compartment based on user habits and external ambient temperature. Using this data, the refrigeration control system can pre-adjust the airflow or temperature of the freezer compartment to avoid uneven airflow, ensure the temperature remains within the set range, and reduce energy consumption. When both the variable-temperature compartment and the freezer compartment are at low temperatures, the operating state of the refrigeration system can be dynamically adjusted through sensors and control algorithms. If the actual cooling demand is not met, the system can postpone the compressor's start-up to avoid unnecessary energy consumption. In this case, the operation of the ventilation component 70 will primarily rely on temperature changes within the variable-temperature compartment, rather than the operation of the refrigeration system.

[0114] Since the temperature difference between the freezer compartment and the variable temperature compartment may not be significant, after the ventilation component 70 draws the cold air from the freezer compartment to the variable temperature compartment, even if the exchange time between the two is extended, the variable temperature compartment may still have difficulty reaching its set ventilation shut-off temperature. In this case, the extended time will waste a lot of cooling time and reduce the cooling effect of both the variable temperature compartment and the freezer compartment.

[0115] Therefore, a timer can be started after the ventilation components are turned on. By limiting the operating time of the ventilation components, if the set temperature is not reached after the first period of ventilation is turned on, the refrigeration system will be activated to simultaneously cool the freezer and variable temperature compartments. This reduces compressor energy consumption, improves the cooling efficiency of the variable temperature compartments, and restores the freezing resources in the freezer compartments. At the same time, since the freezing resources have been distributed to the variable temperature compartments in the early stage, the low temperature intensity of the freezer compartments will not be deepened during the next cooling. This helps to keep both the freezer and variable temperature compartments within a range close to the set temperature, thereby preventing excessive freezing damage to the items stored in the compartments and reducing the waste of freezing resources.

[0116] In some embodiments, the temperatures of the freezer compartment and the variable temperature compartment may be inconsistent. The temperature of the freezer compartment may be lower than the preset temperature of the variable temperature compartment. However, because the set temperature of the variable temperature compartment is lower, it will take a longer time to reach the preset temperature requirement in the later stages of the exchange process. To improve cooling efficiency, an exchange duration needs to be set, such as a first duration. A timer is started after the ventilation components are turned on. After the first duration is reached, the cooling system intervenes to simultaneously cool both the freezer compartment and the variable temperature compartment, thereby improving cooling efficiency.

[0117] In some embodiments, if the freezer room reaches the preset refrigeration system start temperature within the first period after the ventilation component is turned on, the timing is stopped, and the refrigeration system is directly started to cool the freezer room and the variable temperature room simultaneously, so as to avoid affecting the freezing effect of the freezer room.

[0118] Furthermore, based on the above embodiments, the control device 60 can also activate the ventilation component when the refrigeration system is off, the temperature difference between the variable temperature compartment and the freezer compartment is not higher than a preset first temperature difference, and the temperature of the variable temperature compartment is higher than a preset ventilation activation temperature. The first temperature sensor is located inside the freezer compartment and is used to detect the temperature of the freezer compartment inside the refrigerator; the first temperature sensor is connected to the control device 60.

[0119] In some embodiments, when the temperature difference between the freezer room and the variable temperature room is small, that is, when the temperature difference between the variable temperature room and the freezer room is not higher than a preset first temperature difference, the cooling demand of the variable temperature room can be met by simply turning on the ventilation components, without having to start the compressor of the refrigeration system to achieve the cooling process, thereby saving the energy loss and equipment wear and tear caused by starting the refrigeration system.

[0120] In some embodiments, when the refrigeration system is off, the temperature of the variable temperature compartment is not higher than a preset ventilation start temperature, and the temperature of the freezer compartment is higher than a preset refrigeration start temperature, the refrigeration system is turned on, and the ventilation assembly is turned on simultaneously. The first temperature sensor is disposed inside the freezer compartment and is used to detect the temperature of the freezer compartment inside the refrigerator; the first temperature sensor is connected to the control device 60.

[0121] In some embodiments, when there is a cooling demand in the freezer compartment, since the freezer compartment is the compartment with the lowest temperature in the refrigerator, the refrigeration system needs to be activated to cool the freezer compartment regardless of whether the variable temperature compartment has a cooling demand.

[0122] However, since the variable temperature compartment is connected to the freezer compartment, and the variable temperature compartment can be controlled independently, and each compartment has a certain allowable temperature fluctuation range, the variable temperature compartment can be cooled at the same time as the freezer compartment by using the control function of the ventilation component. This allows the compressor of the refrigeration system to start once and simultaneously cool both compartments synchronously, extending the time interval for cooling demand of the variable temperature compartment, thereby reducing the compressor's operating rate and extending the compressor's service life.

[0123] In some embodiments, when the refrigeration system is turned off, the temperature difference between the variable-temperature chamber and the freezer chamber is higher than a preset first temperature difference, and the temperature of the variable-temperature chamber is higher than a preset ventilation start temperature, the ventilation component is turned on for a second period before the refrigeration system is turned on. For example, if the temperature difference between the variable-temperature chamber and the freezer chamber is large, simply using the temperature of the freezer chamber to cool the variable-temperature chamber is no longer sufficient to meet the freezing storage conditions of the freezer chamber. The freezer chamber must be restored to its freezing storage temperature through the refrigeration system. In this case, the refrigeration system is not turned on directly, but the temperature difference between the freezer chamber and the variable-temperature chamber is first balanced. After balancing, the refrigeration system is used to simultaneously cool the two chambers. This avoids the freezer chamber temperature from rising before balancing with the variable-temperature chamber, which would waste freezing resources and could potentially cause frostbite to the items stored in the freezer chamber. Furthermore, because the temperature of the variable-temperature chamber is lowered after balancing, the refrigeration time of the refrigeration system is shortened, which helps to reduce the operating time of the compressor and extend its service life.

[0124] For a refrigerator capable of interacting with a user, the refrigerator may also be equipped with an interactive component, which may include at least one of a function button, a voice acquisition component, and a communication module. In some embodiments, the function button is used to acquire the indication signal corresponding to the user's operation of the button after being triggered by the user. The voice acquisition component is used to collect the user's voice input. The communication module is used to transmit signals to a terminal device associated with the refrigerator. Therefore, for a refrigerator with an interactive component, the refrigerator can be functionally configured to support multiple control modes, with different control modes corresponding to different operating times of at least the refrigeration system.

[0125] For refrigerators that support multiple control modes, some embodiments of this application can also control refrigeration through the following methods, and the following embodiments illustrate two control modes.

[0126] Figure 11 is a schematic flowchart of another refrigerator cooling control method provided in some embodiments of this application. As shown in Figure 11, the method includes:

[0127] S111. When the refrigeration system is turned off and the temperature of the variable temperature room is higher than the preset ventilation opening temperature, the user-selected control mode is obtained.

[0128] In some embodiments, when the temperature of the variable-temperature compartment is higher than the preset ventilation start temperature, it indicates that the variable-temperature compartment needs to be cooled. When the refrigeration system is shut down, the compressor also shuts down simultaneously. However, reducing the compressor's usage rate must be done while meeting user needs; user needs cannot be ignored in pursuit of energy savings, as this would result in a poor user experience. Therefore, to accommodate different user needs, the refrigerator is equipped with interactive components. The refrigerator needs to interact with the user before use, or record historical interaction patterns to better suit user requirements. The control mode selected by the user can be obtained through the following methods:

[0129] Method 1: Obtain the control mode selected by the user through the operation function keys.

[0130] For example, function buttons for different control modes are directly set on the refrigerator, and the corresponding control signals are obtained by the user's triggering.

[0131] Method 2: Obtain the control mode selected by the user through voice input.

[0132] For example, a voice acquisition component can be installed on a refrigerator to collect the user's voice related to the control mode in real time and convert the voice into relevant control commands.

[0133] Method 3: Obtain the selected control mode sent by the user through a terminal device associated with the refrigerator.

[0134] For example, a refrigerator can be connected to a mobile phone. Users can configure the control mode of the refrigerator through their mobile phones. The mobile phone will then convert the user's configuration into a corresponding control request and send it to the refrigerator for processing.

[0135] The aforementioned diversified control methods can enhance the user experience while enabling interactive control of the refrigerator mode. They can also minimize the start-up frequency of the refrigeration system and extend its service life while meeting user habits.

[0136] S112. Determine the target operating time of the refrigeration system based on the control mode selected by the user.

[0137] The control mode includes a first mode and a second mode; the operating time of the refrigeration system in the first mode is greater than the operating time of the refrigeration system in the second mode. For example, in the first mode, the target operating time of the fan during dehumidification is a first duration, and in the second mode, the target operating time of the fan during dehumidification is a second duration, where the first duration is greater than the second duration.

[0138] It should be noted that since the refrigeration system of a refrigerator mainly relies on the operation of the compressor to achieve heat exchange and cooling with the evaporator, the operating time of the refrigeration system can also be regarded as the operating time of the compressor. Because the compressor consumes a significant amount of electricity and inevitably generates noise, but cannot run indefinitely without excessive wear and tear, different control modes are needed to balance the compressor's operation with its own heat dissipation to meet the user's performance or energy-saving requirements.

[0139] For example, the first mode is performance mode, which means the user's need is to quickly cool the target compartment, without considering the energy and equipment losses caused by the compressor's operating time and starting frequency. The second mode is energy-saving mode, which means the user's need is to maintain the temperature of each target compartment in the refrigerator with the least amount of compressor operating time and starting frequency. Here, the temperature maintenance may take a longer time to reach the set temperature range.

[0140] S113. Based on the target operating time of the refrigeration system, turn on the ventilation component or turn on both the ventilation component and the refrigeration system simultaneously.

[0141] In some embodiments, after determining the target operating time, the cooling control method of the control device 60 in the above embodiments is still followed, and the ventilation component is turned on at a specific time, or the ventilation component and the cooling system are turned on simultaneously. The only difference is that the shutdown time after the cooling system is turned on is further limited according to the target operating time. When the operating time is long, the temperature of both the freezer compartment and the variable temperature compartment can be reduced to a deeper temperature that can be maintained for a longer period, thereby using energy loss to further reduce the compressor operating rate.

[0142] In some embodiments, a "transition mode" can be set when there are large temperature fluctuations. This mode starts with a lower compressor operating time during initial use and gradually transitions to normal operating mode. This function reduces excessive compressor workload and extends equipment lifespan by adjusting the start-up frequency and duration of the refrigeration system, without affecting the user experience. The system can monitor the temperature and storage conditions of items inside the refrigerator using sensors to predict the cooling load of each zone, thereby dynamically adjusting the compressor operating time and on / off frequency. For example, if the freezer compartment contains a large amount of recently cooled food, the refrigerator system can automatically extend the compressor's running time, utilizing the natural dissipation of cold air from the frozen items to lower the temperature of the variable-temperature compartment and reduce the burden on the refrigeration system.

[0143] The control methods of some embodiments of this application, based on the determination of the timing of the ventilation component and the refrigeration system to be turned on in the above embodiments, newly add a time limit for the operation of the refrigeration system, and can realize the user's autonomous selection, thereby improving the automation level of the refrigerator and the user's experience.

[0144] Some embodiments of this application also provide a computer-readable storage medium, which may include various media capable of storing program code, such as a USB flash drive, a portable hard drive, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disk.

[0145] In some embodiments, the computer-readable storage medium stores program instructions for the cooling control method described above.

[0146] Some embodiments of this application also provide a program product including executable instructions stored in a readable storage medium.

[0147] At least one control module of the refrigerator can read the execution instruction from a readable storage medium, and the execution instruction by the at least one control module causes the refrigerator to implement the refrigeration control method provided by the various embodiments described above.
