Description

Technical Field

[0001] This application belongs to the field of refrigeration equipment technology, and in particular relates to a refrigerator and its control method, control device and storage medium. Background Technology

[0002] In dual-system refrigerator designs, the evaporator uses a supply and return air technology, and the refrigeration air duct also includes a variable-temperature air duct. Two dampers are required to independently control the cooling needs of the refrigerator compartment and the small variable-temperature compartment. In current market designs, the refrigerator compartment typically doesn't require damper control, while the small variable-temperature compartment achieves independent control through a larger air distribution ratio. However, in some lower-spec models, the small variable-temperature compartment is designed as a simple drawer with a glass shelf, resulting in poor insulation. Therefore, the temperature of the small variable-temperature compartment is often affected by the refrigerator compartment temperature, and the system is usually set to a lower temperature than the refrigerator compartment to ensure the small variable-temperature compartment reaches its target temperature. In this case, the refrigerator compartment's temperature control value may be maintained between 0 and 10°C, but the actual cooling intensity setting may be as low as 2°C to meet the needs of the small variable-temperature compartment. This leads to an excessively low refrigerator compartment temperature, increasing the risk of food freezing and affecting storage performance. Summary of the Invention

[0026] In dual-system refrigerator designs, the evaporator uses a supply and return air technology, and the refrigeration air duct also includes a variable-temperature air duct. Two dampers are required to independently control the cooling needs of the refrigerator compartment and the small variable-temperature compartment. Current market designs typically do not require damper control for the refrigerator compartment, while the small variable-temperature compartment achieves independent control through a larger air distribution ratio. However, in some lower-spec models, the small variable-temperature compartment is designed as a simple drawer with a glass shelf, resulting in poor insulation. Therefore, the temperature of the small variable-temperature compartment is often affected by the refrigerator compartment temperature, and the system is usually set to a lower temperature than the refrigerator compartment to ensure the small variable-temperature compartment reaches its target temperature. In this case, the refrigerator compartment's temperature control value may be maintained between 0 and 10°C, but the actual cooling intensity setting may be as low as 2°C to meet the needs of the small variable-temperature compartment. This leads to excessively low refrigerator compartment temperatures, increasing the risk of ice formation in the crisper drawer and other food items, especially in low-temperature environments where the small variable-temperature compartment temperature reaches -3°C.

[0027] While existing single-door designs can achieve some degree of independent control of the small variable-temperature compartment, the lack of a dedicated damper for adjusting airflow makes temperature control in the refrigerator compartment relatively passive and susceptible to the effects of poor temperature control in the small variable-temperature compartment. This effect is particularly severe in low ambient temperatures, where even slight changes in the refrigerator temperature can cause fluctuations in the refrigerator compartment's temperature, thus affecting the preservation and quality of food.

[0028] In view of the above problems, the present invention, through reasonable design, independently and precisely controls the temperature of the refrigerator compartment and the small variable temperature compartment, avoiding the abnormal drop in temperature of the refrigerator compartment due to the low temperature of the small variable temperature compartment, thereby effectively ensuring the freshness of food and preventing the risk of freezing, and improving the overall performance and user experience of the dual-system refrigerator.

[0029] This application provides a refrigerator and its control method, control device, and storage medium to solve the problem that the temperature of the refrigerator compartment in existing dual-system single-door refrigerators is easily affected by the temperature of the variable temperature compartment, resulting in poor refrigeration performance. The following will be discussed in conjunction with the attached... Figures 1-3 Please provide an explanation.

[0030] The refrigerator control method provided in this application embodiment can be applied to a refrigerator, which has a refrigerator compartment and a variable temperature compartment. The refrigerator air duct also includes a variable temperature air duct, and the variable temperature air duct is equipped with an air damper. For example, please refer to [link to example]. Figure 1 , Figure 1 This is a flowchart illustrating the refrigerator control method provided in an embodiment of this application.

[0031] refer to Figure 1 As shown, the control methods for a refrigerator may include: S101: Obtain the first set temperature of the refrigerator compartment, the second set temperature of the variable temperature compartment, and the ambient temperature; For example, the first set temperature T1 is the storage temperature of the variable temperature compartment set by the user based on the current storage needs of the variable temperature compartment, and the second set temperature T2 is the storage temperature of the refrigerator compartment set by the user based on the current storage needs of the refrigerator compartment. The first and second set temperatures can be set by the user through the refrigerator's control panel or a mobile terminal connected to the refrigerator. For example, the refrigerator is equipped with a control panel, on which the user can select or input temperature parameters for the refrigerator compartment to set its storage temperature.

[0032] In addition to users directly setting the temperature parameters of the compartments, in some other embodiments, the refrigerator has preset multiple storage modes for the variable temperature compartment and / or the refrigerator compartment. Different storage modes correspond to different storage parameters, including temperature parameters, humidity parameters, etc. Users can also select the desired storage mode from multiple storage modes to set the temperature of the variable temperature compartment or the refrigerator compartment.

[0033] Furthermore, the system monitors the ambient temperature in real time by using an ambient temperature sensor located on the outside of the refrigerator (such as the back or top of the refrigerator), which is denoted as the ambient temperature (T3). Ambient temperature is a key external factor affecting the refrigerator's heat load, especially in winter or in air-conditioned rooms, where a decrease in temperature can significantly affect the refrigerator's cooling efficiency and internal temperature distribution.

[0034] During system initialization, a database mapping relationship between ambient temperature and temperature control parameters is established, wherein the temperature adjustment range of the refrigerator compartment is 2-8℃.

[0035] S102: Determine the compensation temperature based on the second set temperature and / or the ambient temperature; When the second set temperature is significantly lower than the first set temperature, it means that the variable temperature compartment needs stronger cooling. Because the variable temperature compartment in lower-configuration models has poor insulation, a large amount of cold air will seep from the variable temperature compartment into the refrigerator compartment. At this time, the algorithm will calculate a basic compensation value based on the temperature difference between the two compartments. The larger the temperature difference, the larger the compensation value.

[0036] In an optional implementation, determining a compensation temperature based on a second set temperature and / or ambient temperature includes: determining a preset temperature range corresponding to the second set temperature when the ambient temperature is lower than a preset temperature threshold; and determining a first compensation temperature based on the preset temperature range and a first set temperature.

[0037] For example, the control system first compares the acquired ambient temperature with an internally preset temperature threshold. This threshold is an empirical value used to determine whether the refrigerator is operating in a low-temperature environment. For example, this threshold can be set to 8°C or 10°C. When the ambient temperature is below this threshold, it indicates that the external environment of the refrigerator is cold, and it is necessary to activate specific temperature compensation logic. If the ambient temperature is not lower than the threshold, the refrigerator can be considered to be in a normal temperature environment, and the compensation logic can be relatively simplified or not executed. This avoids unnecessary compensation in a normal temperature environment, thereby preventing the problem of excessively high refrigerator temperature and ensuring the robustness and accuracy of the control strategy under different seasons and regions.

[0038] The control system can further identify the preset temperature range to which the second set temperature of the variable temperature compartment belongs. In this embodiment, the variable temperature compartment provides three typical function settings, each corresponding to a specific temperature range: chilled (T2≤-3℃), meat (-1℃≤T2<0℃), and fruit and vegetable (T2≥0℃).

[0039] After determining the temperature range of the variable temperature compartment, the system will combine the first set temperature of the refrigerator compartment with a preset mapping relationship (such as a lookup table or formula) to determine the first compensation temperature ΔT1. The design logic of this mapping relationship is: the colder the setting of the variable temperature compartment (i.e., the lower the temperature range), the stronger the cold penetration effect on the refrigerator compartment, and therefore the higher the required compensation temperature, in order to balance the additional cold energy from the variable temperature compartment. This ensures that the final actual temperature of the refrigerator compartment falls exactly within the user's desired preservation range, effectively preventing food from freezing, while not sacrificing the functionality of the variable temperature compartment.

[0040] In an optional implementation, determining the first compensation temperature based on a preset temperature range and a first set temperature specifically includes: when the preset temperature range is a first preset range, using the difference between the first temperature value and the first set temperature as the first compensation temperature; when the preset temperature range is a second preset range, using the difference between the second temperature value and the first set temperature as the first compensation temperature; and when the preset temperature range is a third preset range, determining the value of the first compensation temperature to be 0; wherein the temperature values ​​of the first preset range, the second preset range, and the third preset range increase sequentially, and the first temperature value is greater than the second temperature value.

[0041] For example, when the second set temperature is set to the chilled setting (T2≤-3℃) and the first set temperature T1≤3℃, the first compensation temperature ΔT1=4℃. T1 prevents freezing. If the first set temperature is greater than 3°C, no temperature compensation will be performed, and the first set temperature of the refrigerator compartment will be maintained as the target set temperature.

[0042] When the second set temperature is set to the meat setting ( When the first set temperature T1 ≤ 2℃, the first compensation temperature ΔT1 = 3℃. T1, Optimized Preservation. If the first set temperature is greater than 3°C, no temperature compensation will be performed, and the first set temperature of the refrigerator compartment will be maintained as the target set temperature.

[0043] When the second set temperature is set to fruit and vegetable (T2≥0℃), the first compensation temperature ΔT1=0 (keeping the original set temperature of the refrigerator unchanged).

[0044] This method ensures food safety (no freezing) in the refrigerator compartment when the variable-temperature compartment requires deep cooling (chilling / meat section). Meanwhile, when the variable-temperature compartment has low demand (fruit and vegetable section) and the risk of freezing in the refrigerator compartment is low, the user settings are fully respected, guaranteeing a positive user experience.

[0045] In an optional implementation, determining a compensation temperature based on a second set temperature and / or ambient temperature includes: when the ambient temperature is less than or equal to a preset ambient temperature, determining a second compensation temperature based on the difference between the preset ambient temperature and the ambient temperature and a preset coefficient.

[0046] For example, the control system first determines whether the current ambient temperature is less than or equal to a preset ambient temperature. This preset ambient temperature is a reference point, for example, set to 10°C, to determine whether environmental compensation needs to be activated.

[0047] When the ambient temperature T3 ≤ 10℃, the system considers the refrigerator to be operating at a low temperature. At this time, based on the difference between the preset ambient temperature and the current ambient temperature, and a preset coefficient K, the second compensation temperature (ΔT2) is determined. The calculation formula is: ΔT2 = K × (10 – T3). In this embodiment, the preset coefficient K can be 0.1. Therefore, the specific formula is ΔT2 = 0.1 × (10 – T3).

[0048] For example: when the ambient temperature is 5℃, ΔT2 = 0.1 × (10 5) = 0.5℃. When the ambient temperature is 0℃, ΔT2 = 0.1 × (10 0) = 1.0℃.

[0049] When the ambient temperature is above 10℃, the system considers the negative impact of the environment on temperature control to be relatively small, and can determine the second compensation temperature ΔT2 to be 0. This is achieved by introducing a linear, dynamic environmental compensation mechanism. This allows the compensation amount to increase smoothly as the ambient temperature decreases, rather than through a simple on / off compensation. This refined adjustment can more accurately offset the combined effects of increased refrigeration efficiency and intensified cold penetration caused by low-temperature environments, reducing the likelihood of ice buildup in the refrigerator compartment.

[0050] S103: Based on the compensated temperature, adjust the first set temperature to obtain the target set temperature; After calculating the first compensation temperature (ΔT1) determined by the temperature setting of the variable temperature chamber and the second compensation temperature (ΔT2) determined by the ambient temperature, the system superimposes the two and adjusts the user's original first set temperature T1 to obtain a preliminary target set temperature T0.

[0051] The comprehensive calculation formula is: T0 = T0 + ΔT1 + ΔT2.

[0052] S104: Controls the refrigerator compartment to reach the target set temperature during the refrigeration process.

[0053] By superimposing the two temperature compensation methods mentioned above, a multi-dimensional compensation model is constructed, which can work together to cope with the dual impact of the refrigerator's internal variable temperature compartment and the external environment on the refrigerator compartment temperature, making the refrigerator compartment temperature control more precise.

[0054] In an optional implementation, the control method further includes: when the ambient temperature is less than or equal to a first preset temperature and the duration is greater than a first preset duration, controlling the target set temperature to be greater than or equal to a second preset temperature.

[0055] For example, if the monitored ambient temperature remains ≤5℃ for more than 2 hours, the temperature of the cold storage compartment is forcibly locked at ≥3℃. This prevents the cold storage compartment from freezing due to excessively low temperatures in extreme low-temperature environments, while also avoiding over-cooling in low-temperature environments, which would lead to energy waste and adverse effects on the storage of other foods.

[0056] In an optional implementation, the refrigerator compartment is equipped with a heating device, and the control method includes: acquiring the refrigerator temperature of the refrigerator compartment, and when the difference between the refrigerator temperature and a preset critical temperature is less than a preset difference, controlling the refrigerator compressor to run intermittently and controlling the heating device to turn on.

[0057] In this embodiment, a redundant temperature sensor system can be deployed to achieve dual protection and feedback optimization. When the temperature of the refrigerator compartment is detected to be close to a critical value, such as 2°C, the compressor is triggered to run intermittently, and the heating device of the refrigerator compartment is activated to compensate for the temperature of the refrigerator compartment.

[0058] In an optional embodiment, the refrigerator further includes a fresh produce compartment, which is arranged adjacent to the variable temperature compartment. For example, the fresh produce compartment and the variable temperature compartment are arranged side by side below the refrigerator compartment. The control method further includes: acquiring the current temperature of the fresh produce compartment; determining a third compensation temperature if the current temperature is less than or equal to a third preset temperature; and adjusting a first set temperature based on the third compensation temperature and the compensation temperature to obtain a target set temperature.

[0059] For example, in this embodiment, based on the above compensation mechanism, when the temperature of the fruit and vegetable room area adjacent to the variable temperature room is detected to be ≤1℃, a secondary compensation mechanism is triggered to additionally increase the set temperature of the cold storage room by 1-2℃. This can promptly respond to the low temperature situation that may occur in the fruit and vegetable box area, avoid local low temperature conduction to the cold storage room and cause freezing, and ensure the freshness of fruits and vegetables in the fruit and vegetable room.

[0060] In an optional implementation, the control method further includes: controlling the refrigerator to send a warning message when the current temperature is less than or equal to a fourth preset temperature and the duration is greater than a second preset duration.

[0061] For example, the system is equipped with a temperature anomaly warning module. When the temperature in the fruit and vegetable compartment is detected to be ≤0℃ for 30 minutes, an audible and visual alarm is triggered. This can promptly remind the user that the internal temperature of the refrigerator is abnormal and may affect the safety of food storage. This allows the user to handle the situation in a timely manner and avoid food damage due to prolonged low temperatures. It also helps to detect potential problems in the refrigerator's refrigeration or temperature control in a timely manner and prevents further deterioration of faults such as ice buildup in the refrigerator compartment.

[0062] The refrigerator control method provided in this application includes a refrigerator compartment and a variable temperature compartment. The control method includes: acquiring a first set temperature of the refrigerator compartment, a second set temperature of the variable temperature compartment, and an ambient temperature; determining a compensation temperature based on the second set temperature and / or the ambient temperature; adjusting the first set temperature based on the compensation temperature to obtain a target set temperature; and controlling the refrigerator compartment to reach the target set temperature during the cooling process. Temperature compensation is performed on the refrigerator compartment based on the second set temperature of the variable temperature compartment and the ambient temperature to reasonably adjust the target set temperature (i.e., the actual controlled temperature) of the refrigerator compartment, preventing the refrigerator compartment from becoming too cold and freezing when the variable temperature compartment temperature and the ambient temperature are too low, thus ensuring the best refrigeration effect for food in the refrigerator compartment.

[0063] Secondly, embodiments of this application provide a control device for a refrigerator, the refrigerator being provided with a cold storage compartment and a variable temperature compartment, see reference. Figure 2 As shown, the control device includes: The acquisition module 201 is used to acquire the first set temperature of the cold storage compartment, the second set temperature of the variable temperature compartment, and the ambient temperature. The determining module 202 is used to determine the compensation temperature based on the second set temperature and / or the ambient temperature; The adjustment module 203 is used to adjust the first set temperature based on the compensation temperature to obtain the target set temperature; The control module 204 is used to control the refrigerator compartment to reach the target set temperature.

[0064] The refrigerator control device of this embodiment can be applied to a refrigerator and execute the refrigerator control method of the above embodiment. The specific implementation method can be referred to the above embodiment, and will not be described in detail in this embodiment.

[0065] Thirdly, embodiments of this application provide a refrigerator, including: a refrigerator compartment and a variable temperature compartment; a detection device configured to detect and acquire a first set temperature of the refrigerator compartment, a second set temperature of the variable temperature compartment, and an ambient temperature; a refrigeration system configured to refrigerate the refrigerator compartment and the variable temperature compartment; and a controller electrically connected to the refrigeration system and the detection device, configured to execute the refrigerator control method of the above embodiments.

[0066] By monitoring the ambient temperature, the first set temperature (T1) of the refrigerator compartment, and the second set temperature (T2) of the variable temperature compartment in real time, a temperature compensation strategy is implemented when the ambient temperature is low. Based on the different settings of the variable temperature compartment and the set temperature of the refrigerator compartment, the actual controlled temperature of the refrigerator compartment is adjusted. This meets the storage needs of different foods while preventing icing. For example, when the temperature is set to chilled and T1 ≤ 3℃, the refrigerator compartment temperature is raised to 4℃ to prevent icing caused by low temperatures, while maintaining the low-temperature environment required for chilling. The dual refrigeration system independently regulates the temperatures of the refrigerator compartment and the variable temperature compartment, ensuring that the actual temperature of the refrigerator compartment is always maintained within the safe range of 0-10℃. This allows food to be stored at a suitable temperature, extending its shelf life, reducing the risk of food spoilage due to improper temperature, and preventing icing caused by excessively low refrigerator compartment temperatures.

[0067] Furthermore, the refrigerator is equipped with a two-level compensation mechanism and a dual NTC sensor redundancy design, which improves the accuracy and reliability of temperature detection, avoids temperature detection errors caused by the failure of a single sensor, and thus avoids affecting the refrigerator's temperature control and anti-icing function, ensuring that the entire control method operates based on accurate temperature data.

[0068] Fourthly, embodiments of this application provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the refrigerator control method as described above.

Figure 3 As shown, the electronic device may include a processor 301, a communication interface 302, a memory 303, and a communication bus 304. The processor 301, communication interface 302, and memory 303 communicate with each other via the communication bus 304.

[0070] Furthermore, the logical instructions in the aforementioned memory 303 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of this application can be embodied in the form of a software product. This computer software product is stored in a storage medium and includes several instructions to cause a computer device (which may be a personal computer, server, or network device, etc.) to execute all or part of the steps of the methods in the various embodiments of this application. The aforementioned storage medium includes various media capable of storing program code, such as a USB flash drive, a portable hard drive, a read-only memory 303 (ROM), a random access memory 303 (RAM), a magnetic disk, or an optical disk.

This computer software product can be stored in a computer-readable storage medium, such as ROM / RAM, magnetic disk, optical disk, etc., including several instructions to cause a computer device (which may be a personal computer, server, or network device, etc.) to execute the methods of various embodiments or some parts of embodiments.
