Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a method for temperature control of a refrigerator and its storage compartment. Background Technology

[0002] In related technologies, beverages placed in the bottle holder on the refrigerator door rely on the cold air inside the refrigerator compartment for cooling, which is a slow process. Some refrigerators have a separate "zero-degree" space (temperature set to 0-2℃) for storing beverages. However, setting up a "zero-degree" space generally requires a separate drawer in the refrigerator compartment. Since beverage packaging is mostly cylindrical, using the "zero-degree" space for beverage storage is not very efficient in terms of space utilization.

This is done in addition to the cooling effect of cold air within the refrigerator compartment on the storage compartments, the air supply section and / or the cooling section further cool the storage space itself. The air supply section circulates cold air into the storage compartments, lowering the temperature of the storage space and the items placed within it. The cooling section cools the inner walls of the storage compartments, achieving cooling of the storage space and its contents through heat conduction. When the rapid cooling device includes both an air supply section and a cooling section, this dual cooling method ensures sufficient heat exchange between the surface of the items and the cold air, while the cooling section further accelerates the cooling of the storage space and its contents, thus improving the overall cooling efficiency of the rapid cooling device. Furthermore, by using a rapid cooling device to cool the storage compartments located on the refrigerator door, the need for a separate drawer in the refrigerator compartment to be used for cooling items is eliminated, thereby improving the refrigerator's space utilization.

[0052] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two).

[0053] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0054] like Figures 1 to 8 As shown, the refrigerator of this embodiment includes a door 30, a storage box 20, and a rapid cooling device 10. The storage box 20 includes a box body 21 and a lid 22. The box body 21 is connected to the door 30, and the lid 22 is closable on the box body 21. When the lid 22 is engaged with the box body 21, it forms an item storage space C. The rapid cooling device 10 is configured to cool the items in the item storage space C. The rapid cooling device 10 includes an air supply section 11 and / or a box wall cooling section 12. The air supply section 11 includes an air outlet, which is configured to deliver cold air into the item storage space C. The box wall cooling section 12 is configured to cool the inner wall of the storage box 20.

[0055] By incorporating a rapid cooling device 10 that includes an air supply section 11 and / or a wall cooling section 12, multi-dimensional cooling of the items within the storage compartment 20 is achieved. This is achieved by cooling the storage compartment 20 with cold air from the refrigerator's crisper compartment, and further cooling the storage space C of the storage compartment 20 with the air supply section 11 and / or the wall cooling section 12. The air supply section 11 circulates cold air into the storage compartment 20, thereby reducing the temperature of the storage space C and the items placed within it. The wall cooling section 12 cools the inner wall of the storage compartment 20, achieving cooling of the storage space C and the items within it through heat conduction. When the rapid cooling device 10 includes both the air supply section 11 and the wall cooling section 12, this dual cooling method ensures sufficient heat exchange between the surface of the items and the cold air, while the wall cooling section 12 accelerates the cooling of the storage space C and the items within it, thus improving the overall cooling efficiency of the rapid cooling device 10. In addition, the quick-cooling device 10 is installed to cool the storage box 20 located on the door 30, which avoids occupying a separate drawer in the refrigerator to cool items, thereby improving the space utilization of the refrigerator.

[0056] like Figure 8 As shown, in some embodiments of the refrigerator, the refrigerator further includes a detection device 40 and a control device 50. The detection device 40 is used to detect the temperature of items placed in the item holding space C. The control device 50 is signal-connected to the detection device 40 and the rapid cooling device 10, and is configured to control the rapid cooling device 10 to operate according to the detected temperature.

[0057] By setting up a detection device 40 for detecting the temperature of items placed in the storage space C, and a control device 50 connected to the detection device 40 and the rapid cooling device 10, the control device 50 can control the operation of the rapid cooling device 10 according to the detected temperature. This allows the rapid cooling device 10 to adjust its operating parameters according to changes in the actual temperature of the items placed in the storage space C, achieving precise temperature control of the items in the storage space C. This ensures the items are at optimal temperature conditions, improving the cooling efficiency of the rapid cooling device 10. Furthermore, adjusting various parameters according to the actual temperature of the items helps reduce energy consumption and avoid energy waste. In some embodiments, the detection device 40 detects the temperature of the items placed in the storage space C using an infrared temperature sensor. The infrared temperature sensor can be placed inside the storage box 20 or in the refrigerator compartment. There can be one or more infrared temperature sensors.

[0058] The control device 50 may be implemented as a general-purpose processor, a programmable logic controller (PLC), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or any suitable combination thereof for performing the functions described in this disclosure.

[0059] like Figure 8 As shown, in some embodiments of the refrigerator, the control device 50 is configured to control at least one of the temperature, flow rate and delivery time of the cold air delivered by the air supply section 11 according to the detected temperature; and / or the control device 50 is configured to control the operating temperature and operating time of the box wall cooling section 12 according to the detected temperature.

[0060] By controlling the temperature, flow rate, and delivery time of the cold air supplied by the air supply unit 11, and / or controlling the operating temperature and operating time of the box wall cooling unit 12, precise temperature control of the items within the item-containing space C can be achieved, ensuring the items are under optimal temperature conditions. Furthermore, the detected temperature reflects the actual temperature of the items; adjusting the parameters of the cold air supplied by the air supply unit 11 and / or the box wall cooling unit 12 based on the detected temperature helps reduce energy consumption and avoid energy waste.

[0061] like Figures 2 to 4 As shown, in some embodiments of the refrigerator, the air supply unit 11 includes a door air duct 111 and a connecting assembly 112. The door air duct 111 is disposed inside the door 30. The housing 21 is connected to the door 30 via the connecting assembly 112, which connects the door air duct 111 to the air outlet.

[0062] By setting up a door air duct 111 and a connecting component 112 connecting the door air duct 111 to the air outlet, cold air is stably delivered from the door air duct 111 to the item storage space C, thereby forming a cold air circulation within the item storage space C and cooling the items within the item storage space C. Since the door air duct 111 is located inside the door 30, its installation does not affect the appearance of the refrigerator after the door is opened, and it also facilitates the protection of the door air duct 111, allowing it to operate stably for a long time. Furthermore, the design of the connecting component 112 ensures connection between the storage box 20 and the door 30 without requiring additional components to introduce cold air into the storage box 20, thus simplifying the refrigerator's structure, reducing assembly complexity, and streamlining the production process.

[0063] like Figure 4 As shown, in some embodiments of the refrigerator, the connecting assembly 112 includes a fixing interface 1122 and a hollow hanging member 1121. The fixing interface 1122 is disposed on the door 30. One end of the hollow hanging member 1121 is connected to the box body 21 and communicates with the air outlet, and the other end is fixed to the door 30 through the fixing interface 1122 and communicates with the door air duct 111 through the fixing interface 1122.

[0064] The connecting component 112, in the form of a hollow hanging part 1121 and a fixed interface part 1122, not only connects the air outlet to the door air duct 111, but also connects the storage box 20 to the refrigerator door 30, which helps to simplify the refrigerator structure, reduce assembly complexity, and simplify the production process.

[0065] like Figures 2 to 5 As shown, in some embodiments of the refrigerator, the hollow hanging member 1121 is detachably connected to the fixed interface member 1122 so that the storage box 20 is detachably connected to the door 30.

[0066] By setting the hollow hanging part 1121 to be detachably connected to the fixed interface part 1122, the storage box 20 can be easily removed from the door 30, thus facilitating later maintenance.

[0067] like Figures 2 to 5 As shown, in some embodiments of the refrigerator, the air supply unit 11 includes a door air duct 111 and an exhaust air duct 113. The door air duct 111 is connected to the air outlet. The exhaust air duct 113 is connected to both the door air duct 111 and the cabinet air duct 61 inside the refrigerator body 60.

[0068] By setting up a door air duct 111 and an exhaust air duct 113 connected to the air outlet, the cold air in the box air duct 61 is sequentially passed through the exhaust air duct 113 and the door air duct 111 and then flows out from the air outlet to the item holding space C, thereby cooling the items in the item holding space C.

[0069] like Figure 3 As shown, in some embodiments of the refrigerator, the refrigerator includes a hinge L connecting the cabinet body 60 and the door 30, and the air duct 113 includes a hollow portion 1131 of the hinge L and a connecting channel 1132 located inside the cabinet body 60 between the hollow portion 1131 and the cabinet air duct 61.

[0070] The opening and closing of the door 30 is achieved by setting a hinge L connecting the cabinet 60 and the door 30. The air duct 113 takes the form of a hollow part 1131 of the hinge L and a connecting channel 1132 located inside the cabinet 60 between the hollow part 1131 and the cabinet air duct 61, thereby connecting the cabinet air duct 61 and the door air duct 111, so as to deliver the cold air in the cabinet air duct 61 to the item storage space C. Furthermore, the air duct 113 is hidden inside the hinge L and the cabinet 60, so it will not affect the appearance of the refrigerator after the door is opened, and it is also beneficial for the protection of the air duct 113, so the air duct 113 can work stably for a long time.

[0071] like Figures 5 to 6 As shown, in some embodiments of the refrigerator, the box wall cooling section 12 includes a bottom plate cooling structure 121 located at the bottom of the storage box 20.

[0072] By setting a bottom plate cooling structure 121 at the bottom of the storage box 20, heat exchange is achieved between the cooling part 12 of the box wall and the items placed in the item holding space C through heat conduction, which helps to accelerate the cooling speed of the items and improve the cooling efficiency of the rapid cooling device 10.

[0073] like Figures 5 to 6 As shown, in some embodiments of the refrigerator, the bottom plate cooling structure 121 includes a hollow cavity 1211 and a cooling section disposed within the hollow cavity 1211.

[0074] By setting up a cooling unit, active cooling of the bottom of the box 21 is achieved, thereby accelerating the cooling of the items in the item holding space C.

[0075] like Figures 5 to 6 As shown, in some embodiments of the refrigerator, the cooling section includes a Peltier module; and / or the bottom plate cooling structure 121 also includes a cold storage section disposed within the hollow cavity 1211.

[0076] The cooling section is designed as a Peltier module, which facilitates rapid cooling of the bottom wall of the storage box 20, thereby rapidly cooling the items placed in the item holding space C and improving the cooling efficiency of the rapid cooling device 10. By incorporating a cold storage section within the hollow chamber 1211, cold energy is stored when sufficient and released when needed, thus improving the stability of the rapid cooling device 10 in cooling items. Furthermore, the cold storage section reduces the frequency of start-up and shutdown of the rapid cooling device 10, extending the service life of the cooling section.

[0077] like Figures 5 to 6 As shown, in some embodiments of the refrigerator, the cold storage section includes a coolant tank 1212 and coolant disposed in the coolant tank 1212; and / or the cooling section supplies cold to the inner wall of the storage box 20 by cooling the cold storage section.

[0078] The cold storage section is configured as a coolant tank 1212 and a coolant disposed within it. This design leverages the high heat capacity of the coolant to efficiently store and uniformly release cold energy, thereby maintaining the temperature of the items within the storage box 20. By using a cooling section to cool the cold storage section, and then supplying coolness to the inner wall of the storage box 20 through the cold storage section, an efficient and stable cold energy transfer path is achieved. Furthermore, this method of indirectly transferring cold energy to the inner wall of the storage box 20 through the cooling section results in more uniform cooling of the inner wall of the cooling section 12, thus facilitating uniform cooling of the items.

[0079] The cooling section 12 of the box wall may also include a cooling plate 122, which covers the upper part of the bottom plate cooling structure 121 and is configured to transfer heat between the bottom plate cooling structure 121 and the item holding space C of the storage box 20. The cooling plate 122 is, for example, a metal plate.

[0080] like Figure 2 , Figure 6 and Figure 7 As shown, in some embodiments of the refrigerator, the quick-cooling device 10 further includes a contact assembly 13, through which the quick-cooling device 10 is connected to the refrigerator's circuitry.

[0081] By setting the contact component 13, a reliable connection between the quick-cooling device 10 and the refrigerator circuit is achieved, thereby providing a hardware foundation for the quick-cooling device 10 to be controlled by the control device 50.

[0082] like Figure 2 , Figure 6 and Figure 7 As shown, in some embodiments of the refrigerator, the contact assembly 13 includes: two fixing plates 133; a male contact 131 disposed on the quick-cooling device 10 via one of the two fixing plates 133; and a female contact 132 disposed on the door 30 via the other of the two fixing plates 133, the female contact 132 and the male contact 131 cooperating with each other to connect the quick-cooling device 10 to the refrigerator's circuitry.

[0083] The contact assembly 13 is configured as a fixed plate 133, a male contact 131, and a female contact 132. This facilitates the connection of the quick-cooling device 10 to the refrigerator's circuitry through the interaction of the female contact 132 and the male contact 131, thereby ensuring a reliable connection between the quick-cooling device 10 and the refrigerator's circuitry. Furthermore, the male contact 131 and the female contact 132 are easy to assemble and disassemble, facilitating the detachable connection between the storage box 20 and the door 30.

[0084] Based on the circuitry that enables connection between the rapid cooling device 10 and the refrigerator, the contact assembly 13 is not limited to the form of male contact 131 and female contact 132.

[0085] In some embodiments of the refrigerator, the wall cooling section 12 includes a Peltier module, which is connected to the refrigerator's circuitry via a contact assembly.

[0086] The Peltier module is connected to the refrigerator's circuitry via contact assembly 13, ensuring that the Peltier module can only start working when the contact assembly 13 is connected to the refrigerator's circuitry, which facilitates the control of the Peltier module's operation.

[0087] like Figures 2 to 4 As shown, the second aspect of this application provides a temperature control method for a refrigerator storage box 20 based on the first aspect of this application, comprising: operating the air supply section 11 of the rapid cooling device 10 to deliver cold air to the item storage space C through the air outlet; and / or operating the box wall cooling section 12 of the rapid cooling device 10 to cool the inner wall of the storage box 20.

[0088] By operating the air supply section 11 of the rapid cooling device 10, cold air is delivered into the item holding space C through the air outlet, forming a cold air circulation, thereby reducing the temperature of the item holding space C and the items inside. By operating the box wall cooling section 12 of the rapid cooling device 10, the inner wall of the storage box 20 is cooled, achieving cooling of the item holding space C and the items inside through heat conduction, thereby improving the taste of the items. When the air supply section 11 and the box wall cooling section 12 operate simultaneously, the dual cooling method ensures sufficient heat exchange between the surface of the items and the cold air, and the cooling of the inner wall of the storage box 20 by the box wall cooling section 12 accelerates the cooling of the item holding space C and the items inside, thereby improving the overall cooling efficiency of the rapid cooling device 10.

[0089] like Figure 8 As shown, in some embodiments of the temperature control method of the refrigerator's storage compartment 20, the refrigerator includes a detection device 40 and a control device 50. The control device 50 is signal-connected to the detection device 40 and the rapid cooling device 10. The temperature control method includes: the detection device 40 detecting the detection temperature of the items placed in the item storage space C; the control device 50 controlling at least one of the temperature, flow rate, and delivery time of the cold air delivered by the air supply section 11 according to the detection temperature; and / or the control device 50 controlling the operating temperature and operating time of the cooling section 12 of the compartment wall according to the detection temperature.

[0090] By controlling the temperature, flow rate, and delivery time of the cold air supplied by the air supply unit 11 and / or the operating temperature and operating time of the box wall cooling unit 12, the operating parameters of the rapid cooling device 10 can be adjusted according to the actual temperature changes of the items placed in the item holding space C. This achieves precise temperature control of the items in the item holding space C, ensuring that the items are under optimal temperature conditions and improving the cooling efficiency of the rapid cooling device 10 for the items placed in the item holding space C. Furthermore, adjusting various parameters according to the actual temperature of the items helps reduce energy consumption and avoid energy waste.

[0091] In some embodiments of the refrigerator's storage compartment 20 temperature control method, the temperature control method includes at least one of a quick-cooling mode, a smoothie mode, and a custom mode.

[0092] The temperature control method allows users to set at least one of three modes: rapid cooling, ice-cold mode, smoothie mode, and custom mode. This enables precise temperature control of ingredients and beverages with different cooling requirements through appropriate modes, meeting user needs in different scenarios and thus improving the user experience.

[0093] like Figure 9 As shown, in some embodiments of the temperature control method of the refrigerator's storage compartment 20, in the rapid cooling mode, the temperature control method includes: the control device 50 controls the air supply section 11 and the compartment wall cooling section 12 to operate under a first control mode, wherein the temperature of the cold air blown out of the air outlet is the preset cooling mode cold air temperature, and the operating temperature of the compartment wall cooling section 12 is the preset cooling mode operating temperature. After running the preset cooling mode for a period of time, the detection device 40 detects the temperature of the items. When the temperature difference between the detected temperature and the preset cooling mode cold air temperature is within the preset cooling mode temperature difference range, the control device 50 controls the air supply section 11 and the compartment wall cooling section 12 to continue to operate for a long time, and the cold air temperature and the operating temperature are the preset cooling mode maintenance temperature. When the cooling mode temperature difference is outside the preset cooling mode temperature difference range, the control device 50 controls the air supply section 11 and the compartment wall cooling section 12 to operate again under the first control mode.

[0094] By setting a rapid cooling mode, when the user urgently needs to cool down, the air supply unit 11 and the box wall cooling unit 12 are controlled in coordination to achieve rapid cooling of the items in the item holding space C, and the items can be kept near the target temperature after rapid cooling.

[0095] In some embodiments of the refrigerator's storage compartment 20 temperature control method, the preset cooling mode temperature is greater than the preset cooling mode operating temperature; and / or the preset cooling mode air temperature is in the range of 0℃ to 2℃; and / or the preset cooling mode operating temperature is in the range of -1℃ to 1℃; and / or the preset cooling mode temperature difference range is -0.5℃ to 0.5℃; and / or the preset cooling mode maintenance temperature is equal to the preset cooling mode air temperature; and / or the preset cooling mode time period is in the range of 30min to 60min.

[0096] The preset chilling mode's air conditioning temperature is higher than the preset chilling mode's operating temperature, which facilitates faster cooling of items within the storage space C. The preset chilling mode's air conditioning temperature is within the range of 0℃ to 2℃ and / or the preset chilling mode's operating temperature is within the range of -1℃ to 1℃, which helps to increase the cooling speed of items within the storage space C, especially common beverages, which are unlikely to freeze. By setting the preset chilling mode's temperature difference range to -0.5℃ to 0.5℃, once the temperature of the items within the storage space C reaches near the preset chilling mode's air conditioning temperature, the first control mode is activated, maintaining the item's temperature within a certain range to ensure temperature stability. When the temperature of the items within the storage space C has not reached near the chilling mode's air conditioning temperature, the first control mode is still used, allowing the items to quickly reach near the chilling mode's air conditioning temperature for rapid cooling. The preset chilling mode's maintenance temperature is equal to the preset chilling mode's air conditioning temperature, ensuring that the temperature of the rapidly cooled items remains near the chilling mode's air conditioning temperature, contributing to a better taste. The preset cooling mode time is within the range of 30 to 60 minutes, which helps to ensure the cooling effect while reasonably setting the interval time of the adjustment parameters and reducing energy consumption.

[0097] like Figure 10 As shown, in some embodiments of the refrigerator's storage compartment 20 temperature control method, in smoothie mode, the temperature control method includes: the control device 50 controls the operation of the air supply section 11 and the compartment wall cooling section 12 under a second control mode, wherein the cold air temperature of the cold air blown out of the air outlet and the working temperature of the compartment wall cooling section 12 operate synchronously for a corresponding preset smoothie mode time period at least two preset smoothie mode cold air temperatures and at least two preset smoothie mode working temperatures that are reduced in stages; the control device 50 controls the air supply section 11 and the compartment wall cooling section 12 to continue to operate for a long time, and the cold air temperature and the working temperature are the preset smoothie mode maintenance temperature; wherein at least the last preset smoothie mode cold air temperature, at least the last preset smoothie mode working temperature, and the preset smoothie mode maintenance temperature are all less than 0°C.

[0098] By setting a smoothie mode, an intelligent smoothie-making function is achieved. The control device 50 controls the temperature of the cold air blown out of the air outlet and the working temperature of the cooling section 12 on the box wall to operate synchronously within the corresponding preset smoothie mode time periods, with the cold air temperature and working temperature decreasing in at least two stages. This helps to avoid the phenomenon of the outer layer of the item freezing before the inner layer freezes due to a sudden drop in temperature, effectively avoiding uneven crystallization caused by rapid cooling. Gradual cooling ensures a uniform temperature distribution, which is conducive to a smoother smoothie and achieves the ideal taste. By maintaining the item temperature at the preset smoothie mode maintenance temperature, the quality of the finished smoothie is guaranteed, and energy waste caused by over-freezing is avoided. By setting at least the last preset smoothie mode cold air temperature, at least the last preset smoothie mode working temperature, and the highest value of the preset smoothie mode maintenance temperature range to be less than 0°C, it is ensured that the item can crystallize to form a smoothie, thereby improving the taste of the smoothie.

[0099] In some embodiments of the refrigerator's storage compartment 20 temperature control method, the preset smoothie mode maintenance temperature is between the first preset smoothie mode temperature and the last preset smoothie mode temperature among at least two preset smoothie mode cooling temperatures; and / or the preset smoothie mode maintenance temperature is between the first preset smoothie mode operating temperature and the last preset smoothie mode operating temperature among at least two preset smoothie mode operating temperatures; and / or at least one preset smoothie mode cooling temperature is equal to the same preset smoothie mode operating temperature; and / or at least one preset smoothie mode cooling temperature is greater than the same preset smoothie mode operating temperature; and / or at least two preset smoothie mode cooling temperatures include four preset smoothie mode cooling temperatures, and at least two preset smoothie mode operating temperatures include four preset smoothie mode operating temperatures.

[0100] By setting the preset slush mode to maintain a temperature between the first and last preset slush mode temperatures (out of at least two preset slush mode temperatures), and / or by maintaining the preset slush mode temperature between the first and last preset slush mode operating temperatures (out of at least two preset slush mode operating temperatures), crystallization occurs within the product, forming slush. This slush formation is maintained after it's formed, resulting in a better texture. Setting at least one preset slush mode temperature equal to the operating temperature of the corresponding preset slush mode ensures a more uniform slush, improving its texture. Setting at least one preset slush mode temperature higher than the operating temperature of the corresponding preset slush mode accelerates the product's temperature drop, facilitating rapid slush formation within the product. By setting at least two preset ice smoothie mode air conditioning temperatures, including at least four preset ice smoothie mode air conditioning temperatures, and at least two preset ice smoothie mode operating temperatures, including at least four preset ice smoothie mode operating temperatures, it is beneficial for ice smoothie crystallization to be more uniform, thereby improving the taste of ice smoothie.

[0101] In some embodiments of the refrigerator's storage compartment 20 temperature control method, at least two preset slush mode cooling temperatures include four preset slush mode cooling temperatures, and at least two preset slush mode operating temperatures include four preset slush mode operating temperatures. Each preset slush mode cooling temperature and operating temperature is equal to the corresponding preset slush mode operating temperature. Specifically, the first preset slush mode cooling temperature and the first preset slush mode operating temperature are within the range of 4°C to 8°C; and / or the first preset slush mode time period corresponding to the first preset slush mode cooling temperature and the first preset slush mode operating temperature is within the range of 30 minutes to 60 minutes; and / or the second preset slush mode cooling temperature and the second preset slush mode operating temperature are within the range of 0°C to 4°C; and / or the second preset slush mode cooling temperature and the second preset slush mode operating temperature corresponding to the second preset slush mode operating temperature are within the range of 30 minutes to 60 minutes; and / or the third preset slush mode cooling temperature... The operating temperature of the third-level preset smoothie mode is within the range of -2℃ to 0℃; and / or the air conditioning temperature of the third-level preset smoothie mode and the corresponding time period of the third-level preset smoothie mode are within the range of 30min to 60min; and / or the air conditioning temperature of the fourth-level preset smoothie mode and the corresponding operating temperature of the fourth-level preset smoothie mode are within the range of -8℃ to -5℃; and / or the air conditioning temperature of the fourth-level preset smoothie mode and the corresponding time period of the fourth-level preset smoothie mode are within the range of 15min to 30min; and / or the temperature maintained by the preset smoothie mode is within the range of -1.5℃ to -0.5℃.

[0102] By setting various parameters such as the air conditioning temperature, operating temperature, and time period for each of the four preset smoothie modes, a matching mechanism is achieved between these parameters. This results in finer crystals in the smoothie, ensuring a more uniform and delicate texture and improving the overall taste. The preset smoothie mode maintains a temperature range of -1.5℃ to -0.5℃, ensuring the smoothie retains its state and quality while avoiding energy waste caused by over-freezing.

[0103] like Figure 11 As shown, in some embodiments of the temperature control method for the refrigerator's storage compartment 20, in a custom mode, the temperature control method includes: selecting a custom operating temperature within a preset custom temperature range; the control device 50 controls the air supply section 11 and the compartment wall cooling section 12 to operate in a third control mode, wherein the temperature of the cold air blown out of the air outlet and the working temperature of the compartment wall cooling section 12 are the custom operating temperatures; after running for a preset custom mode period of time, the detection device 40 detects the temperature of the items; when the temperature difference between the detected temperature and the custom operating temperature is within the preset custom mode temperature difference range, the control device 50 controls the air supply section 11 and the compartment wall cooling section 12 to continue operating for a long time, and the cold air temperature and the working temperature are the preset custom mode maintenance temperatures; when the temperature difference between the detected temperature and the custom operating temperature is outside the preset custom mode temperature difference range, the control device 50 controls the air supply section 11 and the compartment wall cooling section 12 to operate again in the third control mode.

[0104] By setting a custom mode, users can select a custom operating temperature within a preset custom temperature range. Once the user selects a specific temperature, the control device 15 will precisely control the temperature of the cold air blown out of the air outlet of the air supply unit 11 and the operating temperature of the cooling unit 12 on the box wall to ensure that the items reach and maintain a temperature close to the custom operating temperature. The custom mode provides users with a more flexible and personalized temperature control solution, allowing users to personalize the storage temperature according to the cooling needs of different items, thus meeting diverse storage requirements while ensuring the accuracy of temperature control.

[0105] In some embodiments of the refrigerator's storage compartment 20 temperature control method, the preset custom temperature range is -2℃ to 15℃; and / or the preset custom mode temperature difference range is -0.5℃ to 0.5℃; and / or the preset custom mode time period is within the range of 30min to 60min; and / or the preset custom mode maintains the temperature within the range of the preset custom temperature ±0.5℃.

[0106] By setting various parameters in the custom mode, users can precisely control the cooling temperature of items under different usage conditions. The preset custom mode running time is within the range of 30 to 60 minutes, which allows for reasonable setting of parameter adjustment intervals while ensuring cooling effect and reducing energy consumption.

[0107] The following combination Figures 1 to 11 A more detailed description will be given of a refrigerator and a temperature control method for a refrigerator storage box 20 according to an embodiment of this application.

[0108] like Figures 1 to 11 As shown, the refrigerator in this embodiment includes a door 30, a body 60, a hinge L connecting the body 60 and the door 30, a storage box 20, a rapid cooling device 10, an infrared temperature sensor as a detection device 40, and a control device 50.

[0109] The storage box 20 includes a box body 21 and a box lid 22. The box body 21 is detachably connected to the box door 30, and the box lid 22 is openable and closable on the box body 21. When the box lid 22 is fastened to the box body 21, it forms an item storage space C with the box body 21.

[0110] Cold air inside the storage box 20 can be discharged from the storage box 20 to the refrigerator's cooling compartment through the gap between the lid 22 and the box body 21, achieving cold air flow within the item storage space C, removing heat from the items, and improving the cooling effect. In embodiments not shown, the storage box 20 may also include a cold air outlet, through which cold air inside the storage box 20 is discharged from the storage box 20 to the refrigerator's cooling compartment, accelerating the cold air flow within the item storage space C of the storage box 20.

The connecting assembly 112 connects the door duct 111 to the air outlet. The connecting assembly 112 includes a hollow hanging member 1121 and a fixing interface member 1122. One end of the hollow hanging component 1121 is connected to the housing 21 and communicates with the air outlet, while the other end is fixed to the housing door 30 through the fixing interface component 1122 and communicates with the housing door air duct 111 through the fixing interface component 1122. In this embodiment, the hollow hanging component 1121 is a hollow L-shaped hook structure.

[0113] The hollow hanging part 1121 is detachably connected to the fixed interface part 1122 so that the storage box 20 is detachably connected to the box door 30.

[0114] The box wall cooling section 12 includes a bottom plate cooling structure 121 and a cold plate 122. The bottom plate cooling structure 121 is located at the bottom of the storage box 20, below the bottom wall of the storage box 20. The bottom plate cooling structure 121 includes a hollow cavity 1211, a Peltier module as a cooling section, and a cold liquid tank 1212 and cold liquid as a cold storage section. The Peltier module is disposed in the hollow cavity 1211 and is used to cool the cold liquid tank 1212. The cold liquid tank 1212 is disposed in the hollow cavity 1211, and the cold liquid is disposed in the cold liquid tank 1212. The Peltier module supplies cooling to the bottom wall of the storage box 20 by cooling the cold liquid tank 1212 and the cold liquid therein. The cold plate 122 covers the upper part of the cold liquid tank 1212 of the bottom plate cooling structure 121 and is configured to transfer heat between the bottom plate cooling structure 121 and the item holding space C of the storage box 20. The cooling plate 122 is, for example, an aluminum plate.

[0115] The rapid cooling device 10 is connected to the refrigerator's electrical circuit via a contact assembly 13. The contact assembly 13 includes two mounting plates 133, a male contact 131, and a female contact 132. The male contact 131 is mounted on the rapid cooling device 10 via one of the two mounting plates 133. The female contact 132 is mounted on the refrigerator door 30 via the other of the two mounting plates 133. The female contact 132 and the male contact 131 cooperate to connect the rapid cooling device 10 to the refrigerator's electrical circuit. In this embodiment, the Peltier module is connected to the refrigerator's electrical circuit via the contact assembly 13.

[0116] An infrared temperature sensor is used to detect the temperature of items placed in the item-containing space C. The infrared temperature sensor is located inside the storage box 20.

[0117] The control device 50 is signal-connected to the detection device 40 and the rapid cooling device 10.

In this embodiment, the control device 50 controls the operating temperature and operating time of the box wall cooling section 12 by controlling the operating temperature and operating time of the Peltier module.

[0118] After the storage box 20 is connected to the door 30 via the hollow hanging bracket 1121, the contact assembly 13 is connected to the refrigerator's circuitry. When beverages or other items requiring cooling are placed into the storage space C, the control device 50 controls the air supply unit 11 to operate, blowing cold air from the air outlet into the storage space C. Simultaneously, the control device 50 controls the cooling unit 12 on the box wall to operate, cooling the bottom wall of the storage box 20 to lower the temperature of beverages and other items, thereby improving their taste.

[0119] The following combination Figures 9 to 11 This application describes an example of a refrigerator's storage compartment 20 temperature control method, which includes a rapid cooling mode, a smoothie mode, and a custom mode.

[0120] like Figure 9 As shown, in the rapid cooling mode, the temperature control method of the storage box 20 includes: the control device 50 controls the operation of the air supply unit 11 and the box wall cooling unit 12 under a first control mode. Under the first control mode, the temperature of the cold air blown out of the air outlet is the preset cooling mode cold air temperature T1, which is within the range of 0℃ to 2℃, for example, T1 is 1℃. The operating temperature of the box wall cooling unit 12 is the preset cooling mode operating temperature T2, which is within the range of -1℃ to 1℃, for example, T2 is 0℃. After running the preset cooling mode for a time period h1, the detection device 40 detects the temperature T of the item. The preset cooling mode time period h1 is within the range of 30min to 60min, for example, h1 is 45min. When the temperature difference between the detected temperature T and the preset cooling mode temperature T1 is within the preset cooling mode temperature difference range of 0.5℃ to 0.5℃, the control device 50 controls the air outlet and the box wall cooling section 12 to continue operating continuously, and the cooling temperature and operating temperature are the preset cooling mode maintenance temperature, such as the preset cooling mode temperature T1. When the temperature difference between the detected temperature and the preset cooling mode temperature is outside the preset cooling mode temperature difference range of -0.5℃ to 0.5℃, the control device 50 restarts the operation of the air supply section 11 and the box wall cooling section 12 under the first control mode.

[0121] like Figure 10 As shown, in smoothie mode, the temperature control method of the storage box 20 includes: the control device 50 controls the operation of the air supply unit 11 and the box wall cooling unit 12 in a second control mode. In the second control mode, the temperature of the cold air blown out of the air outlet and the working temperature of the box wall cooling unit 12 operate synchronously for the corresponding preset smoothie mode time periods at four progressively decreasing preset smoothie mode cold air temperatures and four progressively decreasing preset smoothie mode working temperatures. The cold air temperature of each of the four preset smoothie mode cold air temperatures and the four preset smoothie mode working temperatures is equal to the working temperature of the same preset smoothie mode. The first-level preset slush mode air conditioning temperature T1 is in the range of 4℃ to 8℃, for example, T1 is 6℃; the first-level preset slush mode air conditioning temperature and the corresponding first-level preset slush mode operating temperature time period h1 is in the range of 30min to 60min, for example, h1 is 45min; the second-level preset slush mode air conditioning temperature T2 is in the range of 0℃ to 4℃, for example, T2 is 2℃; the second-level preset slush mode air conditioning temperature and the corresponding second-level preset slush mode operating temperature time period h2 is in the range of 30min to 60min, for example, h2 is 45min; the third-level preset slush mode air conditioning temperature T3 is in the range of -2℃ to 0℃, for example, -1℃; the third-level preset slush mode air conditioning temperature... The temperature and the working temperature of the third-level preset slush mode, corresponding to the time period h3 of the third-level preset slush mode, are in the range of 30 min to 60 min, h3 is, for example, 45 min; the air temperature T4 of the fourth-level preset slush mode is in the range of -8℃ to -5℃, T4 is, for example, -7℃; the air temperature and the working temperature of the fourth-level preset slush mode, corresponding to the time period h4 of the fourth-level preset slush mode, are in the range of 15 min to 30 min, for example, 20 min; then the control device 50 controls the air supply unit 11 and the box wall cooling unit 12 to continue to operate for a long time, and the air temperature and the working temperature are the preset slush mode maintenance temperature T5, the preset slush mode maintenance temperature T5 is in the range of -1.5℃ to -0.5℃, T5 is, for example, -1℃.

[0122] like Figure 11As shown, in the custom mode, the temperature control method includes selecting a custom operating temperature Ti within a preset custom temperature range of -2℃ to 15℃; the control device 50 controls the operation of the air supply section 11 and the box wall cooling section 12 in the third control mode. In the third control mode, the temperature of the cold air blown out of the air outlet and the working temperature of the box wall cooling section 12 are the custom operating temperature Ti. After running the preset custom mode for a period of time, the detection device 40 detects the temperature of the item as the detection temperature T. The custom mode time period h1 is between 30min and 60min, for example, h1 is 45min; when the custom mode temperature difference between the detection temperature T and the custom operating temperature Ti is within the preset custom mode temperature difference range of -0.5℃ to 0.5℃, the control device 50 continues to operate the air supply section 11 and the box wall cooling section 12 for a long time, and the cold air temperature and the working temperature are the preset custom mode maintenance temperature. The preset custom mode maintenance temperature is within the range of the preset custom temperature Ti ± 0.5℃, for example, the preset custom temperature Ti. When the temperature difference between the detected temperature T and the custom operating temperature Ti is outside the preset custom operating temperature difference range of -0.5℃ to 0.5℃, the control device 50 restarts the operation of the air outlet 11 and the box wall cooling section 12 in the third control mode.
