CROSS-REFERENCE TO RELATED APPLICATION

[0001] The present 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

[0002] Some embodiments of the present application relate to refrigerator technology. In particular, the present application relates to a refrigerator, and a refrigeration control method and an operation control method thereof.

BACKGROUND

[0003] To enhance the diversity of refrigerator functions, refrigerators in the related art are provided, in addition to a freezing compartment and a fresh food compartment, with a variable-temperature compartment, enabling users to set the temperature of the variable-temperature compartment between those of the freezing compartment and the fresh food compartment according to actual needs.

[0004] A refrigeration system of the refrigerator mainly includes a compressor and an evaporator. Since the variable-temperature compartment is provided as an auxiliary function, the variable-temperature compartment generally shares the same evaporator with the freezing compartment for refrigeration. As a result, when the variable-temperature compartment requires cooling, the freezing compartment, which is in communication with both the variable-temperature compartment and the refrigeration system, is also subjected to cold air circulation. This causes the low temperature in the freezing compartment to drop further and prolongs the operation time of the compressor. Moreover, since the temperature of the variable-temperature compartment is easily adjusted by user settings, the start-up rate of the compressor is increased to reach the temperature of the variable-temperature compartment, thereby increasing power consumption.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To make some embodiments of the present application clearer, the exemplary embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the exemplary embodiments of the present application. Apparently, the described exemplary embodiments are some rather than all of the embodiments of the present application.

[0024] It should be noted that the brief explanation of terms in the present application is merely for convenience of understanding the following described embodiments, and is not intended to limit the embodiments of the present application. Unless otherwise specified, these terms should be understood according to their ordinary and customary meanings.

[0025] In addition, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a product or device comprising a series of assemblies is not necessarily limited to those assemblies explicitly listed, but may also include other assemblies not explicitly listed or inherent to such products or devices.

[0026] Refrigerators in the related art are provided, in addition to a freezing compartment and a fresh food compartment, with a variable-temperature compartment, enabling users to set the temperature of the variable-temperature compartment between those of the freezing compartment and the fresh food compartment according to actual needs. Since the variable-temperature compartment is an auxiliary function, the variable-temperature compartment is typically arranged between the fresh food compartment and the freezing compartment, and the arrangement space is relatively small. Therefore, a dedicated evaporator for refrigeration is not usually provided for the variable-temperature compartment. To meet the cooling requirements, the variable-temperature compartment generally shares the same evaporator with the freezing compartment for refrigeration.

[0027] When the temperature of the variable-temperature compartment is set to a lower value, since the air supply path from the evaporator to the freezing compartment is relatively short, the temperature in the freezing compartment drops quickly; the air supply path to the variable-temperature compartment is relatively long, so the temperature in the variable-temperature compartment decreases more slowly. This causes the temperature in the freezing compartment to drop further and prolongs the operation time of the compressor. Moreover, since the temperature of the variable-temperature compartment is easily adjusted by user settings, the start-up rate of the compressor is increased to meet the temperature requirement of the variable-temperature compartment, thereby increasing power consumption.

[0028] In view of this, some embodiments of the present application provide a refrigerator. When there is a cooling demand in a variable-temperature compartment, a compressor is not started immediately. Instead, a ventilation assembly 70 between the variable-temperature compartment and a freezing compartment is started. By utilizing the temperature difference between the freezing compartment and the variable-temperature compartment, the cooling capacity in the freezing compartment is first drawn into the variable-temperature compartment. When the temperature reaches the start-up temperature of the freezing compartment, or the temperature of the freezing compartment is equal to the temperature of the variable-temperature compartment and the temperature requirement of any compartment is not met, the compressor is started for the synchronous refrigeration of the freezing compartment and the variable-temperature compartment, so that the energy loss due to excessive refrigeration of the freezing compartment is reduced, and the start-up rate of the compressor is reduced. The refrigerator aims to solve the above problems.

[0029] The technical solutions in some embodiments of the present application are clearly and completely described below with reference to the accompanying drawings in some embodiments of the present application. Apparently, the described embodiments are merely some rather than all of the embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0030] FIG. 1 is a schematic diagram of a refrigerator according to some embodiments of the present application; FIG. 2 is an A-A sectional view of FIG. 1; and FIG. 3 is a schematic diagram of an internal structure of FIG. 1 with a door removed. When a user faces a door of the refrigerator, a width direction of the refrigerator, i.e., a left-right direction, corresponds to an X-axis direction in the drawings; a depth direction of the refrigerator, i.e., a depth direction of compartments, is a front-rear direction and corresponds to a Y-axis direction in the drawings; and a height direction of the refrigerator, i.e., an up-down direction, corresponds to a Z-axis direction in the drawings. The width of the door of the refrigerator refers to a dimension along the X-axis direction when the door is closed, the thickness of the door refers to a dimension along the Y-axis direction when the door is closed, and the height of the door refers to a dimension along the Z-axis direction.

[0031] As shown in FIG. 1, FIG. 2, and FIG. 3, the refrigerator according to some embodiments of the present application includes a door 10 and a cabinet 20. The cabinet 20 includes a storage compartment with an opening on a front side for storing food and other articles. The door 10 is mounted on the front side of the storage compartment and configured to open or close the storage compartment. One storage compartment may be provided; or a plurality of storage compartments may be provided, and the plurality of storage compartments may be arranged at intervals along the height direction and/or the width direction of the refrigerator. For example, the storage compartment may be divided into a freezing compartment, a fresh food compartment, and a variable-temperature compartment according to different storage temperatures. For another example, a shelf may be provided inside the storage compartment to increase the placement positions of articles. For another example, a drawer may be provided within the storage compartment, which is drawable relative to the depth direction of the refrigerator, thereby facilitating the classified storage and retrieval of articles.

[0032] In some embodiments, the door 10 is rotatably mounted on the cabinet 20 to open or close the storage compartment. Exemplarily, the door 10 is rotatably connected to the cabinet 20 via a hinge assembly. When a plurality of storage compartments are provided, one door 10 may be provided, and the plurality of storage compartments share one door 10; or a plurality of doors 10 may be provided corresponding to different storage compartments.

[0033] In some embodiments, at least one shelf is provided on the door 10, and an opening of the shelf faces upward for storing articles. In some embodiments of the present application, a shelf is provided on the door 10 corresponding to the fresh food compartment. A plurality of shelves are arranged at intervals along the height direction of the door 10, thereby further increasing the storage positions of articles. In some embodiments, a plurality of shelves are arranged at non-uniform intervals along the height direction of the door 10. The shelves have different storable heights H. The storable height H of a shelf is a height interval from a supporting plane of the shelf to a bottom surface of an upper shelf; and the storable height H of a topmost shelf is an interval between the shelf and a top seal of the door 10. In this way, when the storage space for articles is increased, compatibility with articles of different heights is achieved.

[0034] In some embodiments, the door 10 may be designed as a multi-layer nested structure with different functional zones. For example, an outermost layer serves as a storage compartment door, while an inner layer may be provided with a small freezer bin or a variable-temperature compartment door. Through the modular design, users can flexibly adjust the refrigeration space according to their storage needs. A door structure compatible with different refrigeration requirements may be provided. For example, the lower half of the door 10 may be designed as a structure with an embedded refrigerator drawer, while the upper half retains the shelf design. This design can effectively enhance the storage flexibility.

[0035] Referring to FIG. 2, the refrigerator according to some embodiments of the present application further includes a compressor 30. The compressor 30 is configured to lower a temperature of the storage compartment, so that the storage compartment can perform refrigeration or freezing tasks according to a preset temperature, thereby prolonging the storage time of articles placed in the storage compartment. In some embodiments, the storage compartment includes a fresh food compartment 211, a variable-temperature compartment 212, and a freezing compartment 213. Referring to FIG. 2 and FIG. 3, the fresh food compartment 211, variable-temperature compartment 212, and freezing compartment 213 are arranged in sequence from top to bottom. In some embodiments, temperature sensors are further provided in the storage compartment and configured to detect the temperature changes of the storage compartment. The temperature sensors are arranged in different storage compartments, including a second temperature sensor 41 in the fresh food compartment 211, a third temperature sensor 42 in the variable-temperature compartment 212, and a first temperature sensor 43 in the freezing compartment 213. In some embodiments, the first temperature sensor 43 may be referred to as a freezing compartment temperature sensor, the second temperature sensor 41 may be referred to as a fresh food compartment temperature sensor, and the third temperature sensor 42 may be referred to as a variable-temperature compartment temperature sensor.

[0036] Continuously referring to FIG. 2, the refrigerator according to some embodiments of the present application further includes a humidity sensor 50. The humidity sensor 50 is configured to detect the humidity of the external air. The humidity sensor 50 may be provided at the top of the cabinet 20 near the refrigerator door 10, so as to relatively accurately detect the humidity of the air entering the storage compartment through the door 10. It may be understood that the humidity sensor 50 may also be provided on a side of the cabinet 20, a bottom surface of the cabinet 20, or even on the rear of the cabinet 20, or on the door 10, as long as the humidity sensor can be in contact with the ambient air.

[0037] Referring to FIG. 3, in some embodiments, an ice-making compartment 214 may further be provided within the fresh food compartment 211. The ice-making compartment 214 is configured to make ice cubes and chilled drinking water. The fresh food compartment 211 is provided with an independent fresh food compartment evaporator 31, which can achieve independent refrigeration and a separate air supply and return system for the fresh food compartment 211 so as to avoid odor transfer between compartments, and can provide a relatively short refrigeration path for the ice-making compartment 214. Continuously referring to FIG. 3, the fresh food compartment 211 adopts a front air supply method for refrigeration. A refrigeration air supply port 331 is provided at an upper part of the fresh food compartment 211, and a refrigeration air return port 332 is provided at a lower part of the fresh food compartment 211. The low-temperature air blown out from the refrigeration air supply port 331 is mixed with the air inside the fresh food compartment 211 to rapidly lower the temperature of the fresh food compartment 211, thereby achieving refrigeration of the fresh food compartment 211. To maintain the refrigeration temperature inside the fresh food compartment 211, the air outlet temperature of the fresh food compartment 211 is usually low (generally≤-15°C), and the temperature near the refrigeration air supply port 331 is even lower. The ice-making compartment 214 may be positioned close to the upper refrigeration air supply port 331, but the mounting position of a water dispensing system should be kept away from this position. In some embodiments, the fresh food compartment evaporator 31 may be referred to as a refrigeration evaporator.

[0038] FIG. 4 is a schematic diagram of an internal structure of FIG. 3 with a fresh food compartment front cover plate removed; and FIG. 5 is a schematic diagram of an internal structure of a fresh food compartment rear panel. Referring to FIG. 4 and FIG. 5, the fresh food compartment 211 includes a fresh food compartment evaporator 31 and a refrigeration fan 32. The refrigeration fan 32 includes a fan, is arranged above the fresh food compartment evaporator 31, and is configured to convey cold air cooled by the fresh food compartment evaporator 31 from an upper refrigeration air supply channel 333 connected to the refrigeration air supply port 331 to the fresh food compartment 211 through the driving of a fan, and convey warm air in the fresh food compartment 211 from a lower refrigeration return air channel 334 connected to the refrigeration return air port 331 to the fresh food compartment evaporator 31 for a next refrigeration circulation inside the fresh food compartment 211. A fourth temperature sensor 44 is further provided within the fresh food compartment 211. The fourth temperature sensor 44 is arranged near the fresh food compartment evaporator 31, for example, at the upper position, and is configured to sense a defrosting temperature of the fresh food compartment evaporator 31, so that the fresh food compartment evaporator 31 can operate efficiently on the premise of temperature indication. Since the fresh food compartment evaporator 31 dries the warm air during refrigeration, the output cold air contains less moisture and is less likely to produce condensation. Therefore, the humidity in the fresh food compartment 211 can be reduced by increasing the rotational speed of the fan. Accordingly, when the humidity of the external environment is high, the humidity of the air entering the fresh food compartment 211 from the outside can be reduced by adjusting the rotational speed of the fan. In some embodiments, the fourth temperature sensor 44 may be referred to as a fresh food compartment evaporator temperature sensor.

[0039] FIG. 6 is a schematic diagram of an external structure of a fresh food compartment rear panel. Referring to FIG. 6, the fresh food compartment evaporator 31 and the refrigeration fan 32 are fixed on a fresh food compartment front cover plate 22 and are covered with a fresh food compartment rear cover plate 23 for physical protection of the fresh food compartment evaporator 31 and the refrigeration fan 32. A refrigeration air return port 332 is provided below the fresh food compartment rear cover plate 23, and a refrigeration air return channel 334 is provided below the fresh food compartment front cover plate 22, so that the air inside the fresh food compartment 211 sequentially passes through the refrigeration air return channel 334 and the refrigeration air return port 332 and enters the refrigeration rear cover plate 23, thereby exchanging heat with the fresh food compartment evaporator 31, then flowing into the upper refrigeration fan 32 and being output into the fresh food compartment 211 through the vortex action of the fan of the refrigeration fan 32 to complete the cold air circulation. Since there is no power assisting device in the above refrigeration air return path, the entire refrigeration air circulation relies on the airflow driven by the fan of the refrigeration fan 32. The fresh food compartment evaporator 31 can reduce the moisture in the air during condensation; and the fresh food compartment evaporator 31 can maintain the refrigeration function for a period of time even after the compressor 30 is turned off.

[0040] In some embodiments, an air duct distribution device is added to the refrigeration air return port 332, so that the airflow can be more uniform to avoid overcooling or temperature instability in certain areas, thereby improving the efficiency of cold air circulation and the temperature stability of the fresh food compartment. A humidity sensor is mounted in the fresh food compartment to automatically adjust the humidity level according to food storage requirements. The humidity control device may cooperate with the fresh food compartment evaporator via a miniature humidifier or dehumidifier to maintain the humidity in the fresh food compartment within a favorable range, thereby preventing food from drying out and reducing frost formation.

[0041] In some embodiments, a tail end of the second temperature sensor 41 is further provided on the fresh food compartment front cover plate 22, while a front end of the second temperature sensor 41 extends into the fresh food compartment 211, thereby avoiding the influence of the temperature of the fresh food compartment front cover plate 22 and the air behind the fresh food compartment front cover plate 22 on the temperature in the actual compartment. Meanwhile, a wire at the tail end and the like are not routed inside the fresh food compartment 211, thereby improving the neatness and aesthetics of the fresh food compartment 211 and protecting the wire.

[0042] Continuously referring to FIG. 5, a sealing rib 335 is further provided at the refrigeration air return channel 334. The sealing rib 335 is arranged along the X-axis direction to block the return warm air after circulation. An air return notch 336 is provided below the fresh food compartment evaporator 31, so that the refrigeration return air can be centrally input to the fresh food compartment evaporator 31 in accordance with the opening path of the refrigeration air return channel 334 and the air return notch 336, thereby improving the cooling efficiency.

[0043] FIG. 7 is a schematic diagram of a front side structure of a rear panel of the variable-temperature compartment and the freezing compartment. Referring to FIG. 2 and FIG. 6, the variable-temperature compartment 212 includes a variable-temperature compartment front cover plate 24. Referring to FIG. 6 and FIG. 7, the variable-temperature compartment front cover plate 24 is provided with a third temperature sensor 42, a variable-temperature compartment air return port 341, and a variable-temperature compartment air supply port 342. The third temperature sensor 42 is provided near the variable-temperature compartment air return port 341, so as to avoid the reduction of the detection accuracy of the actual temperature inside the variable-temperature compartment 212 due to the low temperature of the cold air output from the variable-temperature compartment air supply port 342.

[0044] Continuously referring to FIG. 2 and FIG. 7, the freezing compartment 213 includes a freezing compartment front cover plate 25. The freezing compartment front cover plate 25 is provided with a first temperature sensor 43, a freezing compartment air return port 351, and a freezing compartment air supply port 352. In some embodiments, a plurality of freezing compartment air supply ports 352 are provided to increase the output of cold air. For example, four freezing compartment air supply ports 352 are provided, and the four freezing compartment air supply ports 352 are distributed near the four corners of the freezing compartment front cover plate 25, thereby improving the cooling efficiency. The first temperature sensor 43 is arranged at the middle position to avoid the reduction of the detection accuracy of the actual temperature in the freezing compartment 213 due to the lower temperature of the cold air output from the freezing compartment air supply port 352. Moreover, since a plurality of freezing compartment air supply ports 352 are provided, the temperature inside the freezing compartment 213 can be rapidly reduced and the temperature difference is not significant, so it is unnecessary to consider positioning the first temperature sensor 43 near the freezing compartment air return port 351.

[0045] In some embodiments, the freezing compartment air supply port 352 is arranged with the opening inclined upward, while the freezing compartment air return port 351 is an arc-shaped plate with the opening inclined backward; the arc-shaped plate is arranged below the freezing compartment 213, so that the cold air is blown out from the freezing compartment air supply port 352 and then circulates from top to bottom within the freezing compartment 213 to the arc-shaped plate at the bottom; and the arc shape faces inward toward the compressor 30, so that the circulated air quickly enters the compressor 30, thereby reducing the air path, reducing the loss of low-temperature refrigeration energy, and improving the cooling effect. In addition, the arc-shaped plate facilitates air return and also provides a clearance space for the compressor 30.

[0046] In some embodiments, in addition to providing a plurality of air supply ports 352 on the freezing compartment front cover plate 25, a plurality of air supply port layers in a vertical or horizontal direction may also be provided to help the airflow cover more areas within the freezing compartment, thereby improving the cooling efficiency. By means of layered air supply ports, cold air can be delivered directly to deeper areas, thereby avoiding waste of the cold air. An auxiliary cold air circulation fan may be added at the bottom of the freezing compartment to enhance the air fluidity. By combining the coordinated operation of the freezing fan and the air supply port system, a stronger circulation of cold air is formed within the freezing compartment, and the cold air is rapidly delivered to the corners, especially to areas that are difficult to cool when large articles are stored, thereby enhancing the cooling efficiency.

[0047] FIG. 8 is a schematic diagram of a rear side structure of a rear panel of a variable-temperature compartment and a freezing compartment; and FIG. 9 is a schematic diagram of an internal structure of a rear panel of a variable-temperature compartment and a freezing compartment. Referring to FIG. 8 and FIG. 9, the freezing compartment rear cover plate 26 completely covers the rear of the variable-temperature compartment 212 and the freezing compartment 213. A freezing air duct cover plate separator 27 is provided between the freezing compartment front cover plate 25 and the freezing compartment rear cover plate 26. The freezing air duct cover plate separator 27 is configured to isolate the external environment from the freezing compartment 213, and a freezing air duct is formed through the freezing air duct cover plate separator 27, thereby allowing cold air to flow towards the plurality of freezing compartment air supply ports 352. A freezing fan 36 is further provided within the freezing air duct; the freezing fan 36 includes a fan; an air outlet side of the freezing fan 36 communicates with the freezing compartment air supply port 352; and an air intake side at the rear of the fan of the freezing fan 36 communicates with a freezing evaporator (which is similar in function and structure to the fresh food compartment evaporator and is not shown in the figure). In this way, air cooled by the freezing evaporator is drawn into the freezing air duct and is discharged into the freezing compartment 213 through the freezing compartment air supply port 352, thereby achieving an air cooling circulation process within the freezing compartment 213. In some embodiments, the freezing air duct cover plate separator 27 may be freezing air duct cover plate foam.

[0048] Continuously referring to FIG. 8, in some embodiments, an electric damper 37 is further provided within the freezing air duct. The electric damper 37 is configured to communicate the freezing air duct with the variable-temperature compartment 212, thereby conveying cold air from the freezing air duct into the variable-temperature compartment 212. Since the temperature setting of the variable-temperature compartment 212 cannot be lower than that of the freezing compartment 213, the direct use of the freezing air duct can simultaneously cool the variable-temperature compartment 212 and maintain the low temperature state of the freezing compartment 213, so that the compressor 30 can simultaneously lower the temperatures of both compartments with a single start, and the utilization rate of the compressor 30 can be increased, thereby reducing the number of start-ups of the compressor 30. Similar to the refrigeration return air path, there is no power assisting device in the above freezing return air path. The entire freezing air circulation relies on the airflow driven by the fan of the freezing fan 36. Furthermore, the freezing evaporator can reduce the moisture in the air during the condensation process, and the freezing evaporator can maintain the refrigeration function for a period of time even after the compressor 30 is turned off. In some embodiments, the electric damper 37 may be referred to as a variable-temperature compartment electric damper.

[0049] In some embodiments, a refrigeration air duct may further be provided between the ice-making compartment 214 and the fresh food compartment 211. A fresh food compartment electric damper is provided at the end or inside of the refrigeration air duct. For the structure of the fresh food compartment electric damper, refer to the electric damper 37 shown in FIG. 8. In this way, when the ice-making compartment 214 requires the refrigeration system to start for ice making, a portion of the cold source is also supplied to the fresh food compartment 211, so that a single start of the compressor 30 by the refrigeration system can lower the temperatures of both the ice-making compartment 214 and the fresh food compartment 211 to a required shutdown temperature, thereby reducing the number of start-ups of the compressor 30 due to the cooling demand of the fresh food compartment 211 and prolonging the service life of the compressor 30.

[0050] In some embodiments, when the temperature of the fresh food compartment 211 rises to the activation point of the refrigeration system, the compressor 30 is not immediately started, instead, the fresh food compartment electric damper is first opened, thereby allowing cold air from the ice-making compartment 214 to flow into the fresh food compartment 211 to cool the fresh food compartment 211. Relative to the direct introduction of cold air from the freezing compartment 213 or the variable-temperature compartment 212, the air supply path of the ice-making compartment 214 is shorter. Moreover, since the temperature of the ice-making compartment 214 arranged inside the fresh food compartment 211 is usually set at or slightly below 0°C, while the temperature of the fresh food compartment is typically around 4°C, the temperature difference between the two is not significant. Therefore, while the fresh food compartment 211 is assisted in cooling, excessively low temperature air will not enter the fresh food compartment 211, thereby avoiding condensation or other adverse effects in the fresh food compartment 211.

[0051] It should be noted that the compressor 30, the fresh food compartment evaporator 31, the refrigeration fan 32, the freezing fan 36, and the freezing evaporator not shown in the figure in the above embodiments jointly constitute the refrigeration system of the refrigerator. The refrigeration system can be configured to lower a temperature of the target compartment inside the refrigerator. The following will take the control device 60 of the refrigerator as an executing body to illustrate how the refrigerator performs the refrigeration control method. Some embodiments below may be combined with each other, and the same or similar concepts or processes may not be repeatedly described in some embodiments.

[0052] In some embodiments, as shown in FIG. 12, the control device 60 is respectively connected to a refrigeration system 13, a ventilation assembly 70, a humidity sensor 50, a first temperature sensor 43, a second temperature sensor 41, a third temperature sensor 42, and a fourth temperature sensor 44.

[0053] FIG. 10 is a schematic flowchart of a refrigeration control method of a refrigerator according to some embodiments of the present application. As shown in FIG. 10, the method includes the following steps:
S101: when the refrigeration system is turned off and the temperature of the variable-temperature compartment is higher than a preset ventilation activation temperature, the ventilation assembly 70 is activated, so that air in the freezing compartment flows to the variable-temperature compartment.

[0054] The ventilation activation temperature is used to indicate the ventilation activation temperature of the variable-temperature compartment, that is, when the temperature inside the variable-temperature compartment is detected to be higher than the ventilation activation temperature, it indicates that the variable-temperature compartment does not meet the preset temperature condition at this time and requires cooling. Since temperature detection has a certain fluctuation range, and due to unavoidable spatial defects in the sensor installation position, the detected temperature may not accurately reflect the average temperature inside the target compartment in real time, nor the exact time point of overall temperature change in the target compartment. Therefore, it is necessary to set a temperature range for the activation and deactivation of the refrigeration system, that is, within a certain temperature range, the temperature condition of the target compartment is considered to be met, while exceeding this range requires further control.

[0055] Therefore, the setting basis for the ventilation activation temperature is determined according to a user preset temperature of the variable-temperature compartment. For example, when the user preset temperature of the variable-temperature compartment is -18°C, the ventilation activation temperature can be set to -16°C. When the temperature exceeds -16°C, the control device 60 is required to perform certain operations to lower the temperature of the variable-temperature compartment.

[0056] In some embodiments, the ventilation assembly 70 may include only a duct communicating the variable-temperature compartment with the freezing compartment, or may include both a duct and a fan. The fan is provided within a ventilation duct and can draw air from the freezing compartment into the variable-temperature compartment. In this case, the communicating duct and the fan jointly constitute the ventilation assembly 70.

[0057] In some embodiments, when the refrigeration system of the refrigerator is turned off, in order to maintain the variable-temperature compartment and the freezing compartment within their respective independent temperature ranges, for example, the variable-temperature compartment and the freezing compartment respectively fluctuate within ±2°C of the own set temperature. Closing a passage communicating the variable-temperature compartment with the freezing compartment can provide a certain thermal isolation effect, which is beneficial for maintaining the temperature ranges of the variable-temperature compartment and the freezing compartment. Therefore, the ventilation assembly 70 provided on the passage is not required to be activated and remains in a closed state.

[0058] When the temperature of the variable-temperature compartment exceeds the preset ventilation activation temperature, since the variable-temperature compartment communicates with the freezing compartment, the low temperature of the freezing compartment can be utilized to cool the variable-temperature compartment, thereby enabling the variable-temperature compartment to meet the set temperature requirement and avoiding the start-up of the compressor in the refrigeration system, reducing start-up rate of the compressor, prolonging the service life of the compressor, and reducing the power consumption of the compressor.

[0059] S102: when the temperature of the variable-temperature compartment reaches a preset ventilation deactivation temperature, the ventilation assembly 70 is deactivated.

[0060] The ventilation deactivation temperature is used to indicate the ventilation deactivation temperature of the variable-temperature compartment. In some embodiments, the ventilation deactivation temperature is set by referring to a method for setting the ventilation activation temperature described in the previous step, with the only difference being that the ventilation deactivation temperature is lower than the value of the user preset temperature of the variable-temperature compartment. For example, when the user preset temperature of the variable-temperature compartment is -18°C, the ventilation deactivation temperature may be set to -20°C. When the temperature exceeds - 20°C, the control device 60 is required to perform certain operations to isolate the variable-temperature compartment from a cold source.

[0061] The operation of deactivating the ventilation assembly 70 when a preset ventilation deactivation temperature is reached can prevent articles stored in the target compartment from being affected by temperature beyond the ideal temperature range set by the user, and can also avoid the waste of freezing resources and balance the allocation of cold sources among the compartments in the refrigerator to achieve the optimal utilization rate of the freezing resources, thereby reducing the start-up rate of the compressor in the refrigeration system.

[0062] In some embodiments, based on the above embodiments, the method may further include the following steps:
S103: when the temperature of the variable-temperature compartment does not reach the preset ventilation deactivation temperature after a first duration, the refrigeration system is turned on.

[0063] In some embodiments, the temperatures of the freezing compartment and the variable-temperature compartment in the refrigerator are preset by the refrigerator to be identical. When the variable-temperature compartment does not meet the usage requirements, the freezing compartment may still be within the required freezing range because a large amount of already frozen articles are stored in the freezing compartment and continuously emit cold sources.

[0064] In some embodiments, machine learning or artificial intelligence algorithms are introduced to predict the temperature change trend of the variable-temperature compartment based on the usage habits of users and the ambient temperature. Through the data, a refrigeration control system can adjust the flow of cold air or the temperature of the freezing compartment in advance, thereby avoiding uneven cold air distribution, ensuring that the temperature remains within the set range, and reducing energy consumption. When both the variable-temperature compartment and the freezing compartment are at relatively low temperatures, the working state of the refrigeration system can be dynamically adjusted by sensors and control algorithms. If the actual cooling demand has not been reached, the system can delay the start-up of the compressor, thereby avoiding unnecessary energy consumption. At this time, the operation of the ventilation assembly 70 mainly depends on the temperature changes within the variable-temperature compartment, rather than the operation of the refrigeration system.

[0065] Since the temperature difference between the freezing compartment and the variable-temperature compartment may be small, after the ventilation assembly 70 draws cold air from the freezing compartment into the variable-temperature compartment, it may be difficult for the variable-temperature compartment to reach the set ventilation deactivation temperature even if the exchange time is prolonged. Prolonging the time in this situation will waste a significant amount of refrigeration time and reduce the cooling effect of both the variable-temperature compartment and the freezing compartment.

[0066] Therefore, timing can be started after the ventilation assembly is activated. The operation duration of the ventilation assembly is limited, so that if the set temperature is not reached after the first duration of exchange of the ventilation assembly, the refrigeration system is activated to cool both the freezing compartment and the variable-temperature compartment synchronously. In this way, the cooling efficiency of the variable-temperature compartment is improved on the basis of reducing the energy consumption of the compressor, and the freezing resources of the freezing compartment can be restored. Meanwhile, since the freezing resources have already been shared with the variable-temperature compartment in the initial stage, restarting cooling will not enhance the low-temperature intensity of the freezing compartment, which is beneficial for keeping the freezing compartment and the variable-temperature compartment close to the set temperatures, thereby avoiding the risk of excessive freezing damage to the articles stored in the compartment and reducing the waste of the freezing resources.

[0067] In some embodiments, the temperature of the freezing compartment may not be consistent with that of the variable-temperature compartment, and the temperature of the freezing compartment is lower than the preset temperature of the variable-temperature compartment. However, due to the low set temperature of the variable-temperature compartment, it may take a long time to reach the preset temperature in the later stage of exchange. To improve the cooling efficiency, it is necessary to set an exchange duration, such as a first duration. Timing is started after the ventilation assembly is activated. After the first duration is reached, the freezing compartment and the variable-temperature compartment are cooled synchronously through the intervention of the refrigeration system, thereby improving the cooling efficiency.

[0068] In some embodiments, if the freezing compartment reaches the preset refrigeration system activation temperature within the first duration after the ventilation assembly is activated, timing is stopped and the refrigeration system is directly started to cool the freezing compartment and the variable-temperature compartment simultaneously, thereby avoiding the influence on the freezing effect of the freezing compartment.

[0069] Furthermore, based on the above embodiments, the control device 60 may also activate the ventilation assembly when the refrigeration system is turned off, a temperature difference between the variable-temperature compartment and the freezing compartment is not greater 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 arranged inside the freezing compartment, and the first temperature sensor is configured to detect a temperature of the freezing compartment in the refrigerator. The first temperature sensor is connected to the control device 60.

[0070] In some embodiments, when the temperature difference between the freezing compartment and the variable-temperature compartment is small, that is, when the temperature difference between the variable-temperature compartment and the freezing compartment is not greater than a preset first temperature difference, the cooling demand of the variable-temperature compartment can be met by only activating the ventilation assembly, without starting the compressor of the refrigeration system to achieve the cooling process, thereby saving losses of energy and devices, such as the compressor, caused by starting the refrigeration system.

[0071] In some embodiments, when the refrigeration system is turned off, the temperature of the variable-temperature compartment is not higher than a preset ventilation activation temperature, and the temperature of the freezing compartment is higher than a preset refrigeration activation temperature, the ventilation assembly is activated while the refrigeration system is turned on. The first temperature sensor is arranged inside the freezing compartment, and the first temperature sensor is configured to detect a temperature of the freezing compartment in the refrigerator; and the first temperature sensor is connected to the control device 60.

[0072] In some embodiments, when there is a cooling demand in the freezing compartment, since the freezing compartment is the compartment with the lowest temperature in the refrigerator, it is necessary to turn on the refrigeration system to cool the freezing compartment, regardless of whether there is a cooling demand in the variable-temperature compartment.

[0073] However, since the variable-temperature compartment is connected to the freezing compartment, the variable-temperature compartment can independently control the on and off, and each compartment allows for a certain temperature fluctuation range, the variable-temperature compartment can be cooled by utilizing the on/off control function of the ventilation assembly while the freezing compartment is cooled. In this way, a single start of the compressor in the refrigeration system can simultaneously cool both compartments and extend the interval between cooling demands in the variable-temperature compartment, thereby reducing the start-up rate of the compressor and prolonging the service life of the compressor.

[0074] In some embodiments, when the refrigeration system is turned off, the temperature difference between the variable-temperature compartment and the freezing compartment is greater than the preset first temperature difference, and the temperature of the variable-temperature compartment is higher than a preset ventilation activation temperature, the refrigeration system is turned on after the ventilation assembly is activated for a second duration. For example, if the temperature difference between the variable-temperature compartment and the freezing compartment is large, simply using the temperature of the freezing compartment to cool the variable-temperature compartment will not meet the freezing storage conditions of the freezing compartment. It is necessary for the freezing compartment to restore the freezing storage temperature via the refrigeration system. In this case, the refrigeration system is not turned on directly, but the temperature difference between the freezing compartment and the variable-temperature compartment is balanced first. After balancing, the refrigeration system is used to synchronously cool both compartments, thereby avoiding excessive cooling of the freezing compartment, waste of the freezing resources and adverse effects such as freezing damage to the articles stored in the freezing compartment caused by the fact that when synchronous cooling is performed without balancing the temperature of the freezing compartment and the variable-temperature compartment. Due to the reduction of the temperature of the variable-temperature compartment after balancing, the cooling duration of the refrigeration system is shortened, thereby reducing the service time of the compressor and prolonging the service life of the compressor.

[0075] For a refrigerator that can interact with users, the refrigerator may further be provided with an interaction assembly. The interaction assembly may include at least one of a function button, a voice acquisition assembly, and a communication module. In some embodiments, the function button is configured to, after being triggered by a user, obtain a corresponding indication signal when the user operates the button. The voice acquisition assembly is configured to collect voice input performed by users. The communication module is configured to perform signal transmission with a terminal device associated with the refrigerator. Therefore, for the refrigerator with the interaction assembly, functional settings can be performed on the refrigerator, so that the refrigerator can support a plurality of control modes, where at least operation durations of the refrigeration system corresponding to different control modes are different.

[0076] For the refrigerator supporting the plurality of control modes, some embodiments of the present application may also control refrigeration by the following method. The following embodiments are illustrated by taking two control modes as examples.

[0077] FIG. 11 is a schematic flowchart of another refrigeration control method of a refrigerator according to some embodiments of the present application. As shown in FIG. 11, the method includes:
S111: when the refrigeration system is turned off and the temperature of the variable-temperature compartment is higher than a preset ventilation activation temperature, a control mode selected by a user is acquired.

[0078] In some embodiments, when the temperature of the variable-temperature compartment is higher than a preset ventilation activation temperature, it indicates that the variable-temperature compartment is required to be cooled; when the refrigeration system is turned off, the compressor is turned off synchronously; the usage rate of the compressor is reduced on the basis of meeting the usage requirements of users; and energy reduction should not come at the expense of the requirements of the users, which will cause poor user experience. Therefore, to accommodate different usage requirements of the users, an interaction assembly is provided on the refrigerator. During use, the refrigerator is required to first interact with the users or record historical interaction modes to better meet the usage requirements of the users. The control mode selected by the user includes the following acquisition methods:
Method 1: the control mode selected by the user via operation of the function button is acquired.

[0079] For example, function buttons of different control modes are directly provided on the refrigerator, and corresponding control signals are obtained through the triggering by users.

[0080] Method 2: the control mode selected by the user via voice input is acquired.

[0081] For example, a voice acquisition assembly is provided on the refrigerator to acquire voice of the user related to control modes in real time, and convert the voice into relevant control instructions.

[0082] Method 3: the control mode selected by the user and sent by a terminal device associated with the refrigerator is acquired.

[0083] For example, the refrigerator is interconnected to a mobile phone, and the user configures the control mode for the refrigerator via the mobile phone. The mobile phone converts the configuration of the user into a corresponding control request and sends the control request to the refrigerator for processing.

[0084] The diversified control methods described above not only can achieve user-interactive control of refrigerator modes, but also can enhance user experience, and allow the refrigerator to reduce the start-up frequency of starting the refrigeration system as much as possible while meeting the usage habits of the user, thereby prolonging the service life of the refrigeration system.

[0085] S112: a target operation duration of the refrigeration system is determined according to the control mode selected by the user.

[0086] The control modes include a first mode and a second mode; and the operation duration of the refrigeration system in the first mode is greater than the operation duration of the refrigeration system in the second mode. For example, in the first mode, the target operation duration of the fan during dehumidification is a first duration, while in the second mode, the target operation duration of the fan during dehumidification is the second duration, where the first duration is greater than the second duration.

[0087] It should be noted that since the operation of the refrigeration system of the refrigerator mainly relies on the operation of the compressor to achieve heat exchange with the evaporator for refrigeration, the operation duration of the refrigeration system can also be regarded as the operation duration of the compressor. Since the operation of the compressor consumes a significant amount of electricity and inevitably generates noise, and the compressor cannot run continuously without restriction, otherwise it will cause excessive loss, different control modes are required to balance the operation of the compressor and the heat dissipation of the compressor, thereby meeting the performance or energy-saving requirements of users.

[0088] For example, the first mode is a performance mode, that is, the requirement of the user is to quickly cool the target compartment, regardless of the energy and device losses caused by the working duration and start-up frequency of the compressor. The second mode is an energy-saving mode, that is, the requirement of the user is to maintain the temperature of each target compartment in the refrigerator with minimal working duration and start-up frequency of the compressor. Such temperature maintenance may take a relatively long time to reach the set temperature range.

[0089] S113: according to the target operation duration of the refrigeration system, the ventilation assembly is activated or the ventilation assembly is activated and the refrigeration system is turned on simultaneously.

[0090] In some embodiments, after the target operation duration is determined, the ventilation assembly is still activated at the specified moment according to the refrigeration control method of the control device 60 described above, or the ventilation assembly is activated and the refrigeration system is turned on simultaneously. The only difference is that after the refrigeration system is turned off, the shutdown duration is further limited according to the target operation duration. When the operation duration is relatively long, the temperatures of the freezing compartment and the variable-temperature compartment can be lowered to a deeper level capable of being maintained for a long period, thereby exchanging energy consumption for a further reduction in the start-up rate of the compressor.

[0091] In some embodiments, when there are significant temperature fluctuations, a "transition mode" may be set. This mode starts with a relatively short compressor working duration during initial use, and gradually transitions to the normal working mode. This function reduces excessive compressor operation and prolongs the service life of devices 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 articles inside the refrigerator via sensors, and predict the cooling load of each area, thereby dynamically adjusting the working duration and the on/off frequency of the compressor. For example, if a large quantity of food that has just been cooled is stored in the freezing compartment, the refrigerator system can automatically prolong the operation time of the compressor and utilize the cold air naturally emitted by the frozen articles to lower the temperature of the variable-temperature compartment, thereby reducing the burden on the refrigeration system.

[0092] In some embodiments of the present application, the control method adds a limitation on the operation duration of the refrigeration system based on the determination of the coordinated activation timing of the ventilation assembly and the refrigeration system in the above embodiments. Furthermore, the autonomous selection of users can be achieved, thereby enhancing the automation degree of the refrigerator and improving the usage experience of the users.

[0093] Some embodiments of the present application further provide a computer-readable storage medium. The computer-readable storage medium may include: a USB flash disk, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, an optical disk, or other media that can store program codes.

[0094] In some embodiments, program instructions are stored in the computer-readable storage medium, and the program instructions are used for the refrigeration control method in the above embodiments.

[0095] Some embodiments of the present application further provide a program product. The program product includes execution instructions, and the execution instructions are stored in a readable storage medium.

[0096] At least one control module of the refrigerator may read the execution instructions from the readable storage medium, and the at least one control module executes the execution instructions to enable the refrigerator to perform the refrigeration control method provided by the above embodiments.
