Description

Technical Field

[0001] This application relates to the field of refrigerator technology, such as a control method, device, refrigerator, and computer-readable storage medium for a refrigerator. Background Technology

[0002] Currently, with the improvement of residents' living standards, refrigerators have become an indispensable appliance in households. Traditional refrigerators mostly rely on regulating the overall temperature of the refrigerator compartment, that is, outputting cooling capacity through the main air duct and evaporator to maintain the refrigerator compartment within a fixed temperature range set by the user. However, in actual use, users often place freshly cooked hot dishes, hot soups, or large, hot containers directly into the refrigerator compartment. These hot objects significantly disrupt the temperature distribution within the refrigerator compartment, resulting in insufficient cooling and locally excessively high temperatures, thus affecting food preservation. To address this need, related technologies have proposed a refrigerator product with independent drawers or compartments, allowing users to manually set independent preservation temperatures.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] The air supply methods of related technologies are relatively simple, and there is a lack of precise control over heat sources of different locations, quantities and volumes, which can easily lead to unreasonable distribution of cooling capacity and thus energy waste.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a control method, device, refrigerator, and computer-readable storage medium for a refrigerator, which fundamentally solves the problem of unreasonable cold energy distribution, greatly improves refrigeration efficiency, and achieves significant energy-saving effects.

[0008] In some embodiments, the refrigerator includes: a cabinet with an internally configured refrigerator compartment, wherein a rapid cooling space is provided within the refrigerator compartment; a temperature sensor disposed within the rapid cooling space for detecting the temperature within the rapid cooling space; and a rapid cooling fan disposed within the rapid cooling space for guiding cold air to flow into the rapid cooling space. The control method includes: when a refrigerator door opening / closing action is detected, controlling the temperature sensor to continuously detect the temperature within the rapid cooling space; when the temperature within the rapid cooling space meets the conditions for placing a heat source, determining the heat source information within the rapid cooling space; and, based on the heat source information within the rapid cooling space, controlling the rapid cooling fan to start operation to guide cold air to cool the heat source within the rapid cooling space.

[0009] In some embodiments, the control device includes a processor and a memory storing program instructions, the processor being configured to execute the control method for a refrigerator described above when the program instructions are executed.

[0010] In some embodiments, the refrigerator includes: a cabinet with an internally constructed refrigerator compartment and a rapid cooling space provided inside the refrigerator compartment; a temperature sensor disposed inside the rapid cooling space for detecting the temperature inside the rapid cooling space; a rapid cooling fan disposed inside the rapid cooling space for guiding cold air to flow into the rapid cooling space; and the aforementioned control device for the refrigerator is installed inside the cabinet and electrically connected to the temperature sensor and the rapid cooling fan.

[0011] In some embodiments, the computer-readable storage medium stores program instructions that, when executed, cause the computer to perform the aforementioned control method for the refrigerator.

[0012] The control method, apparatus, refrigerator, and computer-readable storage medium for a refrigerator provided in this disclosure can achieve the following technical effects:

[0013] In this embodiment, when the temperature within the rapid cooling space meets the conditions for placing a heat source, the system further determines the specific heat source information and controls the operation of the rapid cooling fan based on this information. Thus, this embodiment elevates rapid cooling control from a coarse judgment of "whether a heat source is present" to a refined analysis of "what the heat source is." By identifying the specific attributes of the heat source, this embodiment can move away from a "one-size-fits-all" airflow mode and instead provide personalized and refined effective airflow based on actual needs. This allows cooling resources to be accurately and on-demanded to specific targets, fundamentally solving the problem of unreasonable cooling distribution, greatly improving cooling efficiency, and achieving significant energy-saving effects.

Detailed Implementation

[0031] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0038] Users often need to quickly cool high-temperature foods or room-temperature foods while using a refrigerator. Some refrigerators have a rapid cooling function. For example, a refrigerator disclosed in related technology specifically includes: a rapid cooling drawer, located in the rapid cooling compartment of the refrigerator. The rapid cooling drawer has an insulated and sealed cover on top, a refrigerator liner air duct partition on the bottom, a freezer compartment on the left side, a crisper drawer compartment partition on the right side, and a back panel on the back. The cover of the rapid cooling drawer has a rubber strip for sealing; an independent refrigeration pipe, located on one side of the rapid cooling drawer and connected to the refrigerator's refrigeration air outlet; and an independent air damper, located on the independent refrigeration pipe and connected to the refrigerator control panel. The refrigerator can achieve rapid cooling of products to the required temperature in a short time by coordinating the rapid cooling drawer, independent refrigeration pipe, and independent air damper in the rapid cooling compartment. The problem with this technology is that the drawer has an independent refrigeration pipe, which not only requires additional auxiliary components, but also causes energy loss of the cold air in the independent refrigeration pipe, affecting the rapid cooling effect on the object.

[0039] To improve the cooling effect on rapidly cooled objects, combined with Figure 1-8 As shown, this embodiment of the present disclosure provides a rapid cooling component 20 for a refrigeration device. The rapid cooling component 20 includes an air guide structure 101 and a circulating fan 200. The air guide structure 101 includes a housing 100, which defines an air guide duct 140. An air inlet is provided near the first end of the housing 100, and the air inlet is adapted to be openly connected with the cold air forming position of the refrigeration device. An air outlet 148 is provided near the other end of the housing 100. The circulating fan 200 is disposed inside the housing 100. When the fan is running, it draws in air from the air inlet and sends the air out from the air outlet to reduce the temperature of the rapidly cooled object.

[0040] In this embodiment of the disclosure, the refrigeration equipment includes devices such as refrigerators, freezers, and display cases that can create a low-temperature storage environment to extend the shelf life of food and medicines.

[0041] In this embodiment of the disclosure, the air inlet of the air guide duct is used as the air inlet of the air guide duct 140, and the air outlet of the air guide duct 140 is used as the air outlet of the air guide duct 140.

[0042] "The location where the cold air is formed in the refrigeration equipment" refers to the location where the cold air formed or blown out is lower than the temperature of the refrigeration space 12. For air-cooled refrigerators, the location where the cold air is formed is the air outlet of the refrigeration space 12; for direct-cooled refrigerators, the location where the cold air is formed is the location of the refrigeration space 12 near the evaporator.

[0043] "Open connection" is in contrast to the traditional "closed connection". If the air inlet of the air guide duct 140 is sealed to the air outlet of the refrigeration space 12, and air from the refrigeration space 12 is excluded from entering the air inlet of the air guide duct 140, then the air inlet of the air guide duct 140 and the air outlet of the refrigeration space 12 are "sealed connection". Conversely, if the air inlet of the air guide duct 140 is close to the cold air formation position of the refrigeration equipment, and air from the refrigeration space 12 is not excluded or restricted from entering the air guide duct 140 from the air inlet, then the air inlet of the air guide duct 140 and the air outlet of the refrigeration space 12 are in the form of open connection. For example, in the case of a frost-free refrigerator, the refrigerator defines a refrigeration space and has a refrigeration air outlet. The air inlet of the air duct is spaced apart from the refrigeration air outlet of the storage compartment. Cold air enters the refrigeration space through the refrigeration air outlet, then enters the air duct of the quick-cooling component through the air inlet, and then enters the refrigeration space again through the air outlet of the quick-cooling component.

[0044] In this embodiment, the rapid cooling component 20 can be assembled as a separate component into the refrigerated space 12. The housing 100 of the rapid cooling component 20 defines an air duct 140, and the circulating fan 200 of the rapid cooling component 20 is disposed in the air duct 140. The air intake of the rapid cooling component 20 is openly connected to the refrigerated air outlet 14. When the circulating fan 200 is not running, the refrigerated air outlet 14 normally discharges air, uniformly reducing the temperature of the refrigerated space 12. When the circulating fan 200 is running, the air intake of the rapid cooling component 20 draws in the cold air blown out of the refrigerated air outlet 14, and after being pressurized by the circulating fan 200, it is blown towards the object to be rapidly cooled in the refrigerated space 12. When the circulating fan 200 is running, the air velocity and flow rate of the cold air blown towards the object to be rapidly cooled increase, which can reduce the temperature of the object to be rapidly cooled more quickly.

[0045] It should be noted that although some of the air in the refrigerated space 12 may enter the air duct 140 through the air inlet, since the air inlet is located near the refrigerated air outlet 14, the air entering the air duct 140 is mainly the air blown out of the refrigerated air outlet 14. Therefore, the temperature of the air entering the air duct 140 is still relatively low overall.

[0046] For objects requiring rapid cooling, heat convection is the primary method of cooling. The cooling efficiency depends on the temperature difference between the cold air and the object, as well as the velocity and flow rate of the cold air. With the circulating fan running at 200 rpm, the velocity and flow rate of the cold air can be significantly increased, improving the heat transfer effect of the convection cooling process and thus increasing the cooling speed of the object.

[0047] Compared with the "closed connection" form, the open connection form has a shorter overall duct of the air duct 140, so the air volume loss in the air duct 140 is smaller. Under the condition that the power of the circulating fan 200 is constant, the rapid cooling component 20 can carry out heat exchange for the rapid cooling object with higher flow rate and greater flow direction.

[0048] Compared to the form of simply setting a circulating fan 200 to directly blow the object for rapid cooling, the air inlet of the air duct 140 is openly connected to the refrigeration outlet 14. More cold air is drawn in through the air inlet from the refrigeration outlet 14, and the cold air blown out by the rapid cooling component 20 is at a lower temperature, which can reduce the temperature of the object for rapid cooling more quickly.

[0049] Compared to the form of setting up an independent air duct, the rapid cooling component 20 provided in this embodiment of the disclosure will not affect the normal air cooling of the refrigeration outlet 14 when the circulating fan 200 is not working. In addition, the rapid cooling component 20 can be installed on the inner wall of the refrigeration space 12 without being embedded in the foam layer, the air duct structure of the refrigeration equipment is simple, and the manufacturing cost of the refrigeration equipment is low.

[0050] Using the rapid cooling component 20 disclosed in this application, when lowering the temperature of the object being rapidly cooled, the velocity and flow rate of the cold air blown towards the object can be increased, and the temperature of the cold air blown towards the object can be decreased, thereby improving the heat convection heat transfer effect on the object being rapidly cooled and increasing the cooling rate of the object being rapidly cooled. In addition, the open connection between the air duct 140 of the rapid cooling component 20 and the cold storage compartment can reduce the cost increase caused by setting up additional air ducts, and reduce the normal cooling effect of the rapid cooling component 20 on the cold storage space 12 of the refrigeration equipment when the circulating fan 200 is not turned on.

[0051] Optionally, the length dimension of the housing 100 is greater than the height dimension of the housing 100, and the height dimension of the housing 100 is greater than the thickness dimension of the housing 100; wherein, the air guide duct 140 extends along the length direction of the housing 100.

[0052] In this embodiment, "length direction," "height direction," and "thickness direction" all refer to the rapid cooling component 20 in this usage state: the refrigeration device is a front-opening refrigerator, and when the user is facing the refrigerator, the user's vertical direction is the height direction, the user's front-back direction is the depth direction, and the user's left-right direction is the thickness direction. However, this form of expression does not strictly limit the usage of the rapid cooling component 20. For example, in some cases, the rapid cooling component 20 can be used with its length direction along the vertical direction. Figure 7 As shown in the figure, the x-axis represents the length direction, the y-axis represents the thickness direction, and the z-axis represents the height direction.

[0053] The air duct 140 needs to pressurize and deliver cold air from the refrigerated air outlet 14 to the object placed in the refrigerated space 12. Therefore, the rapid cooling component 20 needs to be relatively long, corresponding to the largest length dimension of the housing 100 of the rapid cooling component 20. At the same time, when the rapid cooling component 20 is assembled into the refrigerated space 12, it is necessary to reduce the impact of the rapid cooling component 20 on the capacity of the refrigerated space 12, corresponding to a smaller thickness dimension of the housing 100 of the rapid cooling component 20. When the circulating fan 200 is installed, the size of the housing 100 of the rapid cooling component 20 needs to take into account the diameter of the fan blades of the circulating fan 200. Therefore, the height dimension of the housing 100 is larger than the thickness dimension of the housing 100 and smaller than the length dimension of the housing 100.

[0054] With this configuration, the quick-cooling component 20 is small in size and occupies little space. The refrigerator's capacity and visual appeal will not be significantly affected by the quick-cooling component 20.

[0055] Optionally, the circulating fan 200 is a centrifugal fan. One end face of the circulating fan 200 is at a predetermined distance from the inner wall of the housing 100 to form a low-pressure suction zone 201. An isolation member 210 is provided inside the housing 100 to isolate the low-pressure suction zone 201 from the air duct 140. An air inlet is provided in the housing 100 corresponding to the low-pressure suction zone 201.

[0056] When the circulating fan 200 is a centrifugal fan, the thickness of the rapid cooling component 20 can be made smaller. At the same time, centrifugal fans also have the advantages of lower cost, reliable function, and larger air volume at the same power.

[0057] When the circulating fan 200 is working, the area containing one or two side end faces serves as the low-pressure suction zone 201, while the fan blades at a radial position cooperate with the fan volute to form a high-pressure outlet. The rotation axis of the fan blades of the circulating fan 200 is along the thickness direction of the housing 100. There is a predetermined distance between the circulating fan 200 and the inner wall of the housing 100 to form the low-pressure suction zone 201. This low-pressure suction zone 201 and the low-pressure suction zone 201 of the circulating fan 200 itself are integrated as a whole.

[0058] Since the circulating fan 200 is located within the air duct 140, the isolation chamber can separate the fan installation area 141 of the air duct 140 from other areas, and more specifically, it can separate the aforementioned low-pressure suction area 201 from other areas, which are connected to the high-pressure outlet of the circulating fan 200. With this configuration, an air inlet with a relatively small suction effect can be formed without significantly increasing the thickness of the rapid cooling component 20.

[0059] Optionally, the isolation element 210 includes foam material 211, which is lined between the circulating fan 200 and one end face of the housing 100. The foam material 211 is compressed to isolate the low-pressure intake area 201 and the inclined connection section 142.

[0060] The foam material 211 not only has a sealing and isolating function, but also absorbs fan vibration. When the foam material is compressed and assembled, it can not only absorb the operating noise of the centrifugal fan, thereby reducing the operating noise of the rapid cooling component 20, but also reduce or prevent frost from forming on the housing 100 near the circulating fan 200.

[0061] Optionally, a first air inlet 221 is provided on one end face of the housing 100 along the length direction corresponding to the low-pressure intake zone 201.

[0062] In the case of a frost-free refrigerator, a first air inlet 221 is provided at the rear end of the casing 100 along its length (the end of the rapid cooling component 20 furthest from the user when the user is in front of the refrigerator). The first air inlet 221 is closest to the refrigeration unit, thus providing a more direct airflow. Furthermore, the first air outlet is located at the end furthest from the user, and the first air inlet 221 is in a position that is not easily observed by the user, thereby improving the aesthetics of the rapid cooling component 20 and the refrigeration equipment.

[0063] Optionally, a second air inlet 222 is provided on the downward-facing side of the housing 100 corresponding to the low-pressure intake zone 201.

[0064] The second air vent 222 is located on the downward-facing side of the housing 100. In use, the second air vent 222 is in a position that is not easily observed by the user, which can improve the aesthetics of the rapid cooling component 20 and the refrigeration equipment.

[0065] Optionally, a third air inlet 223 is provided on the outward side of the housing 100 corresponding to the low-pressure intake zone 201.

[0066] The outward-facing side of the housing 100 refers to one end face of the housing 100 along its thickness direction. With the rapid cooling component 20 attached to the left side wall of the housing 100, the third air inlet 223 is located on the right side wall of the rapid cooling component 20. The right side wall of the rapid cooling component 20 has a larger area, allowing for a larger area for the third air inlet 223. This arrangement further increases the airflow area of ​​the rapid cooling component 20, thereby increasing its air output.

[0067] Optionally, the outer side of the housing 100 is recessed inward to form an air inlet groove 131 corresponding to the area of ​​the circulating fan 200. Multiple air inlet slots 132 are formed along multiple radial lines inside the air inlet groove 131. The air inlet groove 131 forms an inclined guide surface from the outside to the inside.

[0068] With this configuration, multiple air inlets 132 allow the front casing 110 to have a relatively complete structure and prevent particulate matter from the refrigeration space 12 from entering the rapid cooling component 20. The air inlet groove 131 is bowl-shaped, forming a guide surface. When air is discharged from the refrigeration outlet 14, the cold air approaches the left and right inner sidewalls of the refrigeration space 12 due to the wall adhesion effect. Through the inclined guide surface, the rapid cooling component 20 can better draw in the cold air approaching the left and right sidewalls of the refrigeration space 12. This configuration increases the air intake volume of the rapid cooling component 20.

[0069] Optionally, the rapid cooling assembly 20 includes an air intake cover 130, which covers the air inlet groove 131, and there is a gap 133 between the periphery of the air intake cover 130 and the peripheral wall of the air inlet groove 131 to allow air to enter.

[0070] With the air intake cover 130 installed, it can obscure multiple air inlet slots 132 from the user's viewing angle. This improves the aesthetics of the rapid cooling assembly 20. Furthermore, the gap 133 formed between the air intake cover 130 and the peripheral wall of the air inlet groove 131 better guides cold air near the left and right side walls of the refrigeration space 12 into the air duct 140 of the rapid cooling assembly 20, thereby increasing the cooling speed of the rapid cooling assembly 20 for the object being rapidly cooled.

[0071] Optionally, the air duct 140 includes a fan installation area 141, an inclined connecting section 142, and an air delivery section 143 arranged sequentially along the air flow direction. The outlet of the circulating fan 200 is higher or lower than the position of the air delivery section 143, and the outlet of the circulating fan 200 is connected to the air delivery section 143 through the inclined connecting section 142.

[0072] The fan installation area 141 is located at the air inlet end of the air duct 140. This increases the cold air transfer distance of the air supply assembly. The circulating fan 200 is a centrifugal fan, so the air outlet direction tends to be along a tangential direction of the circulating fan 200. The air outlet of the circulating fan 200 is higher or lower than the air outlet section 143, so that the air blown from the outlet of the circulating fan 200 can be smoothly and naturally blown towards the air outlet section 143 by tilting the connecting section 142. This arrangement can reduce airflow loss inside the rapid cooling assembly 20.

[0073] Optionally, the air delivery section 143 includes a conveying section 144 and a guide section 146. The conveying section 144 extends along the length of the housing 100 and has an air outlet on its downward side. The guide section 146 extends along the length of the housing 100 corresponding to the air outlet. The guide section 146 is inclined from the inside to the outside and from top to bottom to form a guide slope. The cold air blown out from the air outlet of the conveying section 144 is blown out obliquely downward through the air outlet under the guiding action of the guide section 146.

[0074] The air delivery section 143 has a downward-facing air outlet in its conveying section 144, and a guide section 146 extends along the length of the air outlet, forming a guide slope. When air is blown out from the outlet, it is guided downwards by the guide slope. This arrangement results in the cold air being blown out at a relatively low position. Due to the density difference between hot and cold air, the cold air can better exchange heat with the object being rapidly cooled, and its temperature rises and it moves upwards during the heat exchange process. This optimizes the cold air circulation in the area where the rapid cooling component 20 is located, improving the heat exchange effect between the object being rapidly cooled and the cold air.

[0075] In addition, the downward air outlet and inclined air guide surface of the conveying section 144 make the internal structure of the rapid cooling component 20 less likely to be observed by the user, which can further improve the aesthetics of the rapid cooling component 20 and the refrigeration equipment.

[0076] Optionally, the rapid cooling assembly 20 also includes an illumination module 300, which is disposed on the inner top wall of the conveying section 144. The illumination direction of the illumination module 300 is towards the flow guide section 146 so that the flow guide section 146 presents a light-emitting effect.

[0077] The lighting module 300 is disposed on the inner top wall of the conveying section 144, and the emitted light is directed towards the airflow guide section 146. The projection of the inclined airflow guide surface onto the plane where the lighting module 300 is located coincides with the lighting module 300, so the light emitted by the lighting module 300 can cover most of the area of ​​the inclined airflow guide surface. For example, the light emitted by the lighting module 300 covers more than 95% of the area of ​​the inclined airflow guide surface. Furthermore, when the lighting module 300 emits light, the emitted light is constrained by the two side walls of the conveying section 144 along the thickness direction of the rapid cooling assembly 20, and can only illuminate the inclined airflow guide surface below the air outlet of the conveying section 144. While illuminating the inclined airflow guide surface, the light emitted by the lighting module 300 does not illuminate other locations in the refrigeration space 12.

[0078] The lighting module 300 is located on the top wall inside the conveying section 144, which reduces or prevents condensation buildup and improves the safety of the rapid cooling module. Furthermore, the light emitted by the lighting module 300 is further constrained by the two opposing side walls of the conveying section 144, ensuring it only illuminates the inclined air guide. This arrangement ensures the lighting module 300 emits light without the lamp itself, preventing light leakage. This further enhances the visual appeal of the rapid cooling assembly 20, improving its technological feel and the overall aesthetics of the refrigeration equipment. The integrated design of the lighting module within the rapid cooling assembly allows for easy maintenance by removing or opening the assembly.

[0079] Optionally, the inner top wall of the conveying section 144 is recessed upward to form an assembly space, the lighting module 300 is embedded in the assembly space, and the downward side of the lighting module 300 smoothly docks with the inclined connecting section 142.

[0080] In this case, after installing the lighting module 300, the transition between the inclined connecting section 142 and the air delivery section 143 is relatively smooth, which can reduce the airflow loss inside the rapid cooling component 20.

[0081] Optionally, the ratio of the length of the air outlet to the length of the housing 100 is greater than or equal to 30%; the length of the air guide 146 is equal to the length of the air outlet.

[0082] The air outlet is long and narrow, with its length dimension greater than its height dimension. The ratio of the length of the air outlet to that of the housing 100 is greater than or equal to 30%, allowing the air outlet to cover most of the length of the rapid cooling component 20. When a rapidly cooling object is placed in the refrigeration space 12, the longer air outlet can increase the rapid cooling range and improve the cooling rate of the object.

[0083] The length of the air guide section 146 is equal to the length of the air outlet, thus achieving full coverage of the downward-sloping airflow. When the lighting module 300 emits light, the illumination effect of the inclined air guide surface covers the entire length of the air outlet. This configuration further enhances the rapid cooling component 20 and the lighting display effect, thereby improving the overall display performance of the refrigeration equipment.

[0084] Optionally, the two opposite sidewalls of the air delivery section 143 are arranged in parallel, and the light emitted by the lighting module 300 is constrained by the two parallel sidewalls and illuminates the windward slope.

[0085] The thickness of the air outlet section 143 is equal from top to bottom. Under these conditions, the downward-facing light emitted by the lighting module 300 is approximately parallel. The light shines onto the air guide slope and then enters the human eye through diffuse reflection. This method can reduce or avoid light leakage from the lighting module 300 and make the light emitted by the lighting module 300 more concentrated, thereby improving the lighting display effect of the air guide slope of the rapid cooling component 20.

[0086] Optionally, the lighting module 300 includes a light source board 310, a light doubling plate 320, and a light-shielding material 330. The light source board 310 is provided with a plurality of LEDs; the light doubling plate 320 is provided corresponding to the light source board 310; and the light-shielding material 330 covers the periphery of the light source board 310 and the light doubling plate 320.

[0087] The light source plate 310 of the lighting module 300 is used to emit light, and exemplarily, the light source plate 310 is provided with multiple LEDs. The light-diffusing plate 320 is used to uniformly blend the multiple point light sources of the light source plate 310 into a surface light source. In this way, when the lighting module 300 emits light, local bright spots will not form on the wind-guiding slope. The light-shielding material 330 covers the periphery of the light source plate 310 and the light-diffusing plate 320, which can reduce or avoid light leakage of the lighting module 300. Especially near the housing 100 of the lighting module 300, light is less likely to penetrate the side wall of the housing 100 to form bright bands. In addition, the light-shielding material 330 covering the periphery of the light source plate 310 and the light-diffusing plate 320 can also improve the overall waterproof capability of the lighting module 300.

[0088] Optionally, the light-shielding material 330 is aluminum foil. This not only facilitates the assembly of the lighting module 300, but also provides good light-shielding and waterproof properties. This arrangement further enhances the waterproof and light-leakage prevention capabilities of the lighting module 300.

[0089] Optionally, the housing 100 includes a rear housing 120 and a front housing 110. The rear housing 120 has a recessed area on one side to form an air outlet groove 121 and a recessed area on the other side to form a wiring space 122. The front housing 110 is fitted together with the rear housing 120 and covers the air outlet groove 121 to form an air guide duct 140. The front housing 110 has an air outlet. The air guide portion 146 is an integral structure with the rear housing 120, or the air guide portion 146 is an integral structure with the front housing 110.

[0090] The rear shell 120 is connected to the inner wall of the refrigeration equipment. The side of the rear shell 120 facing the refrigeration space 12 is recessed away from the refrigeration space 12 to form an air outlet groove 121, and the side of the rear shell 120 away from the refrigeration space 12 is recessed towards the refrigeration space 122 to form a wiring space 122. This improves the structural strength of the rear shell 120, thereby improving the overall structural strength of the housing 100. The front shell 110 covers the air outlet groove 121 of the rear shell 120, forming an air duct 140. An air outlet is provided on the side of the front shell 110 facing the refrigeration space 12. The airflow guide 146 is an integral structure with the front shell 110 or the rear shell 120, which simplifies the number of components in the housing 100 and reduces the assembly difficulty of the rapid cooling assembly 20.

[0091] With this configuration, the circulating fan 200, lighting module 300 and corresponding connecting harness can be easily installed in the rear housing 120, and the wiring space 122 is isolated from the air duct 140.

[0092] Optionally, the air duct 140 includes a fan installation area 141, an inclined connecting section 142, and an air delivery section 143 arranged sequentially along the airflow direction, with the outlet of the circulating fan 200 being higher or lower than the air delivery section 143; the rapid cooling assembly 20 also includes a circulating fan 200, which is located in the fan installation area 141, and the outlet of the circulating fan 200 is connected to the air delivery section 143 through the inclined connecting section 142.

[0093] Optionally, a temperature detection hole 124 is provided on the same side of the housing 100 as the air outlet, and a temperature detection area 125 is formed inside the housing 100 corresponding to the temperature detection hole 124, which is isolated from the air duct 140; the rapid cooling component 20 also includes an infrared temperature sensor 400, which is disposed in the temperature detection area 125, and the infrared temperature sensor 400 detects the temperature of the rapidly cooled object and / or the background temperature through the temperature detection hole 124.

[0094] Temperature detection port 124, third air inlet 223, and air outlet are all located on the outward-facing side of housing 100. A temperature detection area 125 is formed inside housing 100. Since this temperature detection area 125 is isolated from the air duct 140, it reduces or prevents the infrared temperature sensor 400 from being affected in terms of temperature detection. The infrared temperature sensor 400 detects the temperature of the object being rapidly cooled, which can be used to determine whether to cool the object and to determine the fan speed based on the object's temperature. The infrared temperature sensor 400 detects the background temperature, which can determine whether the area corresponding to the infrared temperature sensor 400 is too hot or too cold, thereby controlling the start / stop of the rapid cooling component 20.

[0095] This configuration allows the infrared temperature sensor 400 to identify the temperature of the rapidly cooled object, providing a basis for decision-making regarding the start-up, shutdown, and speed of the circulating fan.

[0096] Optionally, the rapid cooling component 20 also includes a battery 510 disposed within the housing 100.

[0097] When the quick-cooling component 20 also includes a battery 510, the quick-cooling component 20 can drive the circulating fan 200 to rotate without the refrigerator providing power. This not only frees the installation location of the quick-cooling component 20 from the limitations of wiring harness connections, but also allows the quick-cooling component 20 to be adapted to different types of refrigerators. The quick-cooling component 20, with its built-in battery 510, can also provide quick-cooling functionality to a refrigerator that does not already have it.

[0098] Optionally, the rapid cooling component 20 also includes a manual switch connected to the circulating fan 200.

[0099] When the user needs to use the rapid cooling function, they turn on the manual switch of the rapid cooling component 20. After rapid cooling is complete, the user manually turns off the rapid cooling component 20. This allows the rapid cooling function of the rapid cooling component 20 to operate independently of a temperature sensor and processor, simplifying the structure of the rapid cooling component 20 and reducing its cost.

[0100] Optionally, the rapid cooling assembly 20 also includes a battery 510 and a timing switch 520, which is connected to the circulating fan 200.

[0101] In one application scenario, after a user places a refrigerated object inside, the rapid cooling component 20 needs to rapidly cool it for approximately half an hour. The user can turn on the timer switch 520 or set it to half an hour, and the circulating fan 200 will automatically stop after half an hour. This setup further simplifies the user experience.

[0102] Combination Figure 1-8As shown, this embodiment of the present disclosure provides a refrigerator, which includes a cabinet 10 and the aforementioned rapid cooling component 20. The cabinet 10 defines a refrigeration space 12, and a refrigeration air outlet 14 is provided on the rear wall of the refrigeration space 12. The rapid cooling component 20 is installed on the inner wall of the refrigeration space 12, and the air inlet of the rapid cooling component 20 is openly connected to the refrigeration air outlet 14. The air outlet of the rapid cooling component 20 faces the object to be rapidly cooled placed in the refrigeration space 12.

[0103] The refrigerator includes a cabinet 10 and a door. The cabinet 10 defines a refrigeration compartment 12, and the door is used to open or close the refrigeration compartment 12. A refrigeration air outlet 14 is provided on the rear wall of the refrigeration compartment 12. The aforementioned rapid cooling component 20 is installed on the left or right side wall of the refrigeration compartment 12. The rapid cooling component 20 is installed horizontally, with the air inlet located at one end near the rear wall of the refrigeration compartment 12, and the air outlet facing the object to be rapidly cooled in the refrigeration compartment 12.

[0104] The refrigerator disclosed in this application can achieve normal refrigeration cooling in the refrigerator compartment 12 when the fan of the rapid cooling component 20 is not activated. After a rapidly cooling object is placed in the refrigerator compartment 12, the circulation fan 200 of the rapid cooling component 20 is activated, which can quickly reduce the temperature of the rapidly cooling object. Using the refrigerator disclosed in this application, when reducing the temperature of the rapidly cooling object, the flow rate and volume of the cold air blown towards the rapidly cooling object can be increased, and the temperature of the cold air blown towards the rapidly cooling object can be reduced, thereby improving the heat convection heat transfer effect on the rapidly cooling object and increasing the cooling rate of the rapidly cooling object. In addition, the open connection between the air duct 140 of the rapid cooling component 20 and the refrigerator compartment can reduce the cost increase caused by setting up an additional air duct, and reduce the normal cooling effect of the rapid cooling component 20 on the refrigerator compartment 12 when the circulation fan 200 is not activated.

[0105] The inner walls of the refrigerated compartment 12 include a left side wall, a right side wall, a top side wall, a bottom wall, and a rear wall. When partitions or other dividing components are provided inside the refrigerated compartment 12, the top side wall of the refrigerated compartment 12 also includes a side with the partition facing downwards, or the bottom side wall of the refrigerated compartment 12 also includes a side with the partition facing upwards.

[0106] Optionally, a rapid cooling component 20 as described above may be provided on the left and right walls of the refrigerated space 12.

[0107] This configuration can further improve the cooling speed of rapidly cooled objects.

[0108] Optionally, the rapid cooling component 20 can be detached and fitted to the inner wall of the refrigerated space 12.

[0109] The refrigerator provided in this embodiment is equipped with a rapid cooling component 20, which can quickly reduce the temperature of a rapidly cooled object in a region of the refrigeration space 12. The rapid cooling component 20 is detachable and can be installed in different compartments or regions of the refrigeration space 12 according to actual needs, thereby improving rapid cooling efficiency and making it more convenient for users.

[0110] Optionally, the rapid cooling component 20 also includes a suction cup 530, which is used to attach the rapid cooling component 20 to the inner wall of the refrigeration space 12.

[0111] The rapid cooling component 20 is equipped with a suction cup 530, which can adhere to the smooth inner wall of the refrigeration space 12. When rapid cooling of an object is required, the rapid cooling component 20 is attached to the designated area. When changing positions, the suction cup 530 can be depressurized to easily remove the rapid cooling component 20. With this design, the rapid cooling component 20 is easy to install and remove, and the cost is low.

[0112] Optionally, the suction cup 530 of the rapid cooling component 20 is at least partially located inside the housing 100.

[0113] As an optional implementation, the housing 100 of the quick-cooling component 20 is constructed with an adsorption groove, and the suction cup 530 is disposed in the adsorption groove. In this way, after the quick-cooling component 20 is assembled into the refrigeration space 12, the quick-cooling component 20 will not protrude too much from the inner wall of the cabinet 10, which can improve the aesthetics of the refrigerator and reduce the impact on the capacity of the refrigeration space 12 caused by the installation of the quick-cooling component 20.

[0114] Optionally, the side wall of the cabinet 10 is provided with a first magnetic suction member 15, and the rapid cooling component 20 includes a second magnetic suction member 540. The first magnetic suction member 15 and the second magnetic suction member 540 cooperate to fix the rapid cooling component 20 to the inner wall of the refrigeration space 12.

[0115] In one optional embodiment, the inner liner 11 of the refrigerated space 12 is a metal inner liner 11, which serves as the first magnetic chuck 15. The rapid cooling assembly 20 is equipped with a magnet, which serves as the second magnetic chuck 540. In another optional embodiment, a metal sheet is embedded in the foam layer of the inner liner 11, which serves as the first magnetic chuck 15, and the rapid cooling assembly 20 is equipped with a magnet, which serves as the second magnetic chuck 540. The rapid cooling assembly 20 is detached and reassembled using the cooperation of the first magnetic chuck 15 and the second magnetic chuck 540, which not only further facilitates user operation but also optimizes the feel of detaching and reassembling the rapid cooling assembly 20.

[0116] Optionally, the side wall of the cabinet 10 is provided with a first mating part 16, and the rapid cooling assembly 20 includes a second mating part 550. The first mating part 16 and the second mating part 550 cooperate to fix the rapid cooling assembly 20 to the inner wall of the refrigeration space 12.

[0117] As an optional implementation, the first mating part 16 is a screw hole, and the second mating part 550 is a screw. The quick-cooling component 20 is fixed to the inner wall of the refrigeration space 12 by passing screws through it. This arrangement provides a better fixing effect for the quick-cooling component 20, and the implementation cost of the detachable structure of the quick-cooling component 20 and the refrigerator is relatively low.

[0118] As an alternative implementation, the side wall of the housing 10 is provided with a hook-on portion, and the rapid cooling component 20 is provided with a hook-on mating portion. The rapid cooling component 20 is fixed to the inner wall of the refrigeration space 12 by a snap-fit ​​connection. With this arrangement, the rapid cooling component 20 can be accurately positioned in the installation position, which is beneficial to the realization of the rapid cooling function of the rapid cooling component 20.

[0119] Optionally, the cabinet 10 includes an inner liner 11 and an air duct assembly 13, wherein the inner liner 11 encloses and defines a refrigerated space 12; the air duct assembly 13 is disposed on the rear wall of the refrigerated space 12 and at a predetermined distance from the left and right walls of the refrigerated space 12, and a refrigerated air duct is formed inside the air duct assembly 13, with the air outlet of the refrigerated air duct directed towards the left and right walls.

[0120] The inner liner 11 of the cabinet 10 defines a refrigeration space 12, and the air duct assembly 13 is used to form a refrigeration air duct in the refrigeration space 12. Specifically, the air duct assembly 13 is attached to the rear wall of the inner liner 11 and at a predetermined distance from the left and right side walls of the inner liner 11. When the air duct assembly 13 blows air out, it directs cold air towards the left and right side walls of the inner liner 11. With this arrangement, the refrigeration air will not blow directly onto the user when the refrigerator is opened, reducing cold air loss and improving the user experience. While the air duct assembly 13 is blowing air towards the left and right side walls of the inner liner 11, a rapid cooling assembly 20 is provided to pressurize and deliver cold air to the target area for rapid cooling. This clearly distinguishes the rapid cooling function of the refrigerator from the ordinary refrigeration function.

[0121] Optionally, the distance between the air inlet of the rapid cooling component 20 and the rear wall of the refrigeration space 12 is greater than or equal to 10 mm and less than or equal to 50 mm.

[0122] The rear wall of the refrigerated space 12 is defined relative to the front side of the air duct assembly 13. When the air inlet of the rapid cooling assembly 20 is openly connected to the refrigerated air outlet 14, if the distance between the air inlet and outlet is too small, it will be difficult for the rapid cooling assembly 20 to draw in cold air, affecting its airflow. If the distance is too large, most of the air entering the air inlet will be from the refrigerated space 12, resulting in higher outlet temperatures and impacting the cooling speed of the refrigerated object. When the distance between the air inlet of the rapid cooling assembly 20 and the rear wall of the refrigerated space 12 is between 10 mm and 50 mm, the rapid cooling assembly 20 draws in a larger volume of cold air, which is then directed towards the outlet 14. This configuration further improves the cooling speed of the rapid cooling assembly 20 for the refrigerated object.

[0123] Optionally, a wireless charging coil is provided in the foam layer of the refrigerator, and a wireless charging module is provided in the quick-cooling component 20.

[0124] In this configuration, the user can charge the rapid cooling component 20 simply by placing it on the location of the wireless charging coil; the charging process also takes place within the refrigeration compartment 12. This further enhances the convenience of using the rapid cooling component 20.

[0125] Optionally, the refrigerator forms a rapid cooling zone 17 in the refrigeration space 12, and the rapid cooling component 20 is disposed in the rapid cooling zone 17.

[0126] With this configuration, the refrigerator can achieve zoned cooling for different areas of the refrigeration space.

[0127] Optionally, embodiments of this disclosure provide a refrigerator, including: a cabinet, a temperature sensor, and a rapid cooling fan. The cabinet has an internal refrigerator compartment, and a rapid cooling space is provided within the refrigerator compartment. The temperature sensor is located inside the rapid cooling space and is used to detect the temperature within the rapid cooling space. The rapid cooling fan is located inside the rapid cooling space and is used to guide cold air to flow into the rapid cooling space.

[0128] In the following description, "rapid cooling space" and "rapid cooling area" are the same terms, "cold storage room" and "cold storage space" are the same terms, and "heat source" and "rapid cooling object" are the same terms.

[0129] Optionally, the refrigerator also includes a control device 600, installed inside the refrigerator body and electrically connected to a temperature sensor and a rapid cooling fan. Thus, embodiments of this disclosure can use the control device 600 to execute corresponding control methods to rapidly cool the refrigerator when a user places a heat source inside.

[0130] Based on the above refrigerator, combined with Figure 9As shown, this disclosure provides a control method for a refrigerator, including:

[0131] S101, when the refrigerator door is detected to be opening or closing, the control device controls the temperature sensor to continuously monitor the temperature in the rapid cooling compartment.

[0132] S102, the control device controls the operating status of the rapid cooling fan according to the temperature in the rapid cooling space.

[0133] The refrigerator control method provided in this disclosure uses the opening and closing of the refrigerator door as one of the triggering conditions. Under this condition, the local temperature in the rapid cooling compartment is continuously monitored, and the operation of the rapid cooling fan is controlled based on this temperature. Therefore, this disclosure creates a direct and efficient rapid cooling triggering mechanism. By linking specific human-machine interactions with changes in local temperature, the system can quickly sense and respond the moment a heat source is placed in the refrigerator. This fundamentally overcomes the response lag of traditional passive control, ensuring that cooling resources are delivered instantly when most needed, thereby significantly improving the cooling efficiency of the heat source.

[0134] Optionally, the control device controls a temperature sensor to continuously detect the temperature within the rapid cooling space, including: the control device controls an infrared temperature sensor to continuously detect the temperature within the rapid cooling space. Wherein, combined with Figure 7 As shown, an infrared temperature sensor can be installed inside the rapid cooling assembly. The infrared temperature sensor is located in the temperature detection area and can detect the heat source temperature and / or ambient temperature through a temperature detection port.

[0135] Thus, this embodiment of the present disclosure utilizes an infrared temperature sensor to continuously monitor the temperature within the rapid cooling space, achieving non-contact, high-sensitivity detection of heat sources. The infrared temperature sensor can quickly detect the infrared radiation emitted by a high-temperature object, thereby accurately determining its presence the moment it is placed inside. This provides a reliable triggering basis for the immediate response of the rapid cooling function, effectively avoiding failure or delayed startup of the rapid cooling function due to sensor response lag.

[0136] Optionally, the control device controls a temperature sensor to continuously monitor the temperature within the rapid cooling space, including: the control device controls an NTC (Negative Temperature Coefficient) thermistor to continuously monitor the temperature within the rapid cooling space. The NTC thermistor can be mounted on a shelf within the rapid cooling space. The shelf is located at the bottom of the rapid cooling space and is used to place objects to be rapidly cooled. The shelf has a hollow cavity inside, and multiple thermistors are positioned within the hollow cavity at different detection locations. These thermistors can be used to detect some or all of the information regarding the heat source, including its temperature, location, size, and quantity.

[0137] Thus, this embodiment of the present disclosure utilizes NTC thermistors to continuously monitor the temperature within a rapidly cooling space. When deployed in a distributed array configuration, it can provide highly localized and refined temperature data. This enables the system not only to determine the presence of a heat source but also to accurately pinpoint the actual location, quantity, and approximate size of the heat source by analyzing temperature data from different NTC points. This provides a solid data foundation for subsequent directional or differentiated airflow strategies, significantly improving the accuracy and efficiency of cooling capacity distribution.

[0138] Optionally, the control device controls the operating status of the rapid cooling fan according to the temperature in the rapid cooling space, including: when the temperature in the rapid cooling space meets the conditions for placing a heat source, the control device controls the rapid cooling fan to start running, so as to guide cold air to cool the heat source in the rapid cooling space; when the temperature in the rapid cooling space meets the conditions for the heat source to reach the required temperature, the control device controls the rapid cooling fan to stop running, so as to stop guiding cold air to cool the heat source in the rapid cooling space.

[0139] Thus, the embodiments of this disclosure can start the rapid cooling fan when the temperature in the rapid cooling space meets the conditions for placing the heat source, and stop the rapid cooling fan when the temperature in the rapid cooling space meets the conditions for the heat source to reach the required temperature. This constructs a complete closed-loop control logic for rapid cooling, realizes on-demand operation of the rapid cooling fan, avoids unnecessary long-term operation, and effectively reduces energy consumption.

[0140] Optionally, in some embodiments, the rapid cooling fan is located at the refrigeration air outlet inside the rapid cooling space, so that more cold air in the main air duct of the refrigeration compartment is diverted to the interior of the rapid cooling space.

[0141] In this embodiment, the rapid cooling fan is placed inside the rapid cooling space, utilizing the main air duct of the refrigerator compartment to deliver cold air. This effectively utilizes the existing main air duct and cold air circulation of the refrigerator, avoiding the complexity of establishing an additional independent air duct system. By embedding the rapid cooling fan within the target rapid cooling space, existing cold air resources are utilized locally and efficiently, thereby simplifying the overall air duct design and effectively reducing manufacturing costs.

[0142] Furthermore, combined Figure 1-8 As shown, the rapid cooling fan can be installed inside the rapid cooling component. In this case, the circulating fan 200 of the rapid cooling component is equivalent to the rapid cooling fan.

[0143] Thus, this embodiment of the present disclosure can improve the heat convection heat transfer effect on the heat source and increase the cooling rate of the heat source by increasing the flow rate and volume of the cold air blown towards the heat source while lowering the temperature of the heat source. Furthermore, the open connection between the air duct of the rapid cooling component and the refrigerator compartment reduces the cost increase caused by setting up additional air ducts and also reduces the normal cooling effect of the rapid cooling component on the refrigerator compartment when the circulating fan is not running.

[0144] Alternatively, in other embodiments, the rapid cooling space is connected to the freezer compartment via an auxiliary air duct, and the rapid cooling fan is located at the outlet of the auxiliary air duct corresponding to the interior of the rapid cooling space, so that more cold air in the freezer compartment is diverted to the interior of the rapid cooling space.

[0145] Alternatively, in other embodiments, the rapid cooling space is connected to the freezer compartment via an auxiliary air duct, and the rapid cooling fan is located at the inlet of the freezer compartment corresponding to the auxiliary air duct, so that more cold air in the freezer compartment is diverted to the interior of the rapid cooling space.

[0146] In this embodiment, the rapid cooling fan is positioned at the outlet or inlet of the auxiliary air duct connected to the freezer compartment, allowing low-temperature cold air from the freezer compartment to be delivered into the rapid cooling space, providing it with a lower temperature and a more powerful cooling source. By utilizing the low-temperature cold air from the freezer compartment, the system can more powerfully and rapidly cool the placed high-temperature heat source, thereby significantly improving the efficiency and performance of the rapid cooling function. This ensures that regardless of the heat source temperature, it can be effectively cooled in the shortest possible time, meeting the user's extreme rapid cooling needs.

[0147] Optionally, the conditions for placing the heat source include: the temperature in the rapid cooling space is greater than or equal to the preset start-up temperature; and the temperature change rate in the rapid cooling space is greater than or equal to the preset temperature change rate.

[0148] In this way, the embodiments of this disclosure can use the temperature and temperature change rate in the rapid cooling space to determine the conditions for placing a heat source, overcoming the misjudgment defects caused by single-dimensional judgment, thereby accurately identifying the real heat source placement event, effectively eliminating false triggering caused by human hand taking things or heat source being taken out before closing the door, improving the accuracy and reliability of the rapid cooling function, and thus avoiding energy waste caused by misjudgment.

[0149] Optionally, the preset start-up temperature can be set in conjunction with the internal refrigeration temperature. For example, the preset start-up temperature can be set to 10°C to eliminate false triggering caused by removing the heat source before closing the door, thereby identifying the actual heat source insertion event. The preset start-up temperature can also be adjusted according to the user's actual needs or set to any other reasonable value.

[0150] Optionally, the preset temperature change rate can be set based on the difference between the external ambient temperature and the internal refrigeration temperature. For example, the preset temperature change rate can be set to 2℃ / s to eliminate false triggers caused by human handling, thereby identifying genuine heat source placement events. The preset temperature change rate can also be adjusted according to the user's actual needs or set to any other reasonable value.

[0151] Optionally, the temperature within the rapid cooling space includes the heat source temperature and the ambient temperature; the conditions for the heat source to reach the desired temperature include: the heat source temperature within the rapid cooling space is less than or equal to the preset shutdown temperature; and / or, the difference between the heat source temperature within the rapid cooling space and the ambient temperature is less than or equal to the preset shutdown temperature difference; and / or, the continuous operating time of the rapid cooling fan is greater than or equal to the preset operating time.

[0152] In this way, the embodiments of this disclosure can use a combination of various heat source temperature conditions for judgment, including whether the temperature of the heat source in the rapid cooling space is low, whether the temperature difference between the heat source temperature and the ambient temperature is small, and whether the continuous running time of the fan is long, etc., thereby providing multiple and flexible judgment criteria for the precise shutdown of the rapid cooling function, which can not only ensure that the heat source is sufficiently cooled, but also stop the operation in time, avoid over-cooling, and ensure energy efficiency.

[0153] Optionally, the preset shutdown temperature can be set in conjunction with the internal refrigeration temperature. For example, the preset shutdown temperature can be set to 6°C to ensure sufficient cooling of the heat source, thereby achieving precise shutdown of the rapid cooling function. The preset shutdown temperature can also be adjusted according to the user's actual needs or set to any other reasonable value.

[0154] Optionally, the preset shutdown temperature difference can be set in conjunction with the internal refrigeration temperature. For example, the preset shutdown temperature difference can be set to 2°C to ensure sufficient cooling of the heat source, thereby achieving precise shutdown of the rapid cooling function. The preset shutdown temperature difference can also be adjusted according to the user's actual needs or set to any other reasonable value.

[0155] Optionally, the preset running time can be set in conjunction with the internal refrigeration temperature. For example, the preset running time can be set to 12 hours to ensure that the heat source is sufficiently cooled, thereby achieving precise shutdown of the rapid cooling function. The preset running time can also be adjusted according to the user's actual needs or set to any other reasonable value.

[0156] Optionally, the temperature within the rapid cooling space includes the heat source temperature and the ambient temperature; after the control device starts the rapid cooling fan, it also includes: the control device adjusting the operating speed of the rapid cooling fan according to the heat source temperature within the rapid cooling space. The operating speed of the rapid cooling fan is positively correlated with the heat source temperature within the rapid cooling space.

[0157] In this way, the embodiments of this disclosure can establish a positive correlation between the operating speed of the rapid cooling fan and the temperature of the heat source in the rapid cooling space, so as to realize the dynamic adjustment of the cooling intensity according to the heat source load. That is, the higher the heat source temperature, the higher the operating speed of the rapid cooling fan is set accordingly, and the stronger the cold energy delivery to the rapid cooling space is, thereby improving the rapid cooling efficiency, shortening the cooling time, and optimizing the on-demand distribution of energy.

[0158] Optionally, the control device adjusts the operating speed of the rapid cooling fan according to the heat source temperature in the rapid cooling space, including: when the heat source temperature in the rapid cooling space is greater than a first heat source temperature threshold, the control device outputs a first speed command to make the rapid cooling fan run at a high speed; or, when the heat source temperature in the rapid cooling space is less than or equal to the first heat source temperature threshold and greater than a second heat source temperature threshold, the control device outputs a second speed command to make the rapid cooling fan run at a medium speed; or, when the heat source temperature in the rapid cooling space is less than or equal to the second heat source temperature threshold and greater than a preset shutdown temperature, the control device outputs a third speed command to make the rapid cooling fan run at a low speed.

[0159] Thus, this embodiment of the invention can adjust the operating speed of the rapid cooling fan in stages according to the temperature of the heat source within the rapid cooling space, thereby achieving on-demand matching of rapid cooling intensity. When the heat source temperature is high, the fan operates at a high speed to quickly lower the temperature; as the temperature gradually decreases, the fan speed is correspondingly reduced, thus avoiding unnecessary energy waste. This gradient intelligent control ensures a precise correspondence between cooling output and heat load, significantly improving cooling efficiency and energy utilization.

[0160] Optionally, after the control device starts the rapid cooling fan, it further includes: the control device acquiring the operating level of the cold storage compartment; and the control device adjusting the operating speed of the rapid cooling fan according to the operating level of the cold storage compartment. The operating speed of the rapid cooling fan is negatively correlated with the target cold storage temperature corresponding to the operating level.

[0161] In this way, the embodiments of this disclosure establish a negative correlation between the operating speed of the rapid cooling fan and the operating setting of the refrigerator compartment, so as to coordinate the local rapid cooling function with the overall refrigeration strategy of the refrigerator. That is, the stronger the operating setting and the lower the target refrigeration temperature, the higher the operating speed of the rapid cooling fan is set accordingly, and the stronger the cold air delivery to the corresponding rapid cooling space. This ensures that the rapid cooling fan always operates at the most suitable speed under different main operating settings, taking into account both the rapid cooling effect and the overall refrigeration effect of the refrigerator, and ensuring that the rapid cooling space is always in a highly efficient and energy-saving operating state at different refrigeration temperatures.

[0162] Optionally, the control device adjusts the operating speed of the rapid cooling fan according to the operating setting of the refrigerator compartment, including: when the target refrigerator temperature corresponding to the operating setting of the refrigerator compartment is less than a first refrigerator temperature threshold, the control device outputs a first speed command to make the rapid cooling fan run at a high speed; or, when the target refrigerator temperature corresponding to the operating setting of the refrigerator compartment is greater than or equal to the first refrigerator temperature threshold and less than a second refrigerator temperature threshold, the control device outputs a second speed command to make the rapid cooling fan run at a medium speed; or, when the target refrigerator temperature corresponding to the operating setting of the refrigerator compartment is greater than or equal to the second refrigerator temperature threshold, the control device outputs a third speed command to make the rapid cooling fan run at a low speed.

[0163] In this way, the embodiments of this disclosure can dynamically adjust the operating speed of the rapid cooling fan according to the operating setting of the refrigerator compartment, thereby deeply integrating the local rapid cooling function with the overall operating strategy of the refrigerator. By linking the speed of the rapid cooling fan with the user-set temperature setting of the refrigerator compartment, the system can ensure that the rapid cooling operation is always consistent with the overall cooling target of the refrigerator, such as reducing the rapid cooling intensity accordingly in the energy-saving setting. This not only maintains the overall stability of the internal temperature of the refrigerator but also avoids additional energy consumption caused by functional conflicts.

[0164] Optionally, the control method further includes: when the temperature in the rapid cooling space meets the conditions for placing a heat source, the control device controls the ambient light to start running, so as to remind the user that the cold air is cooling the heat source in the rapid cooling space.

[0165] In this way, the embodiments of this disclosure can provide users with intuitive functional status prompts through the activation of ambient lights, enhancing the user-friendliness of human-computer interaction, enabling users to clearly perceive the activation of the rapid cooling function, and improving the user experience.

[0166] Optionally, after the control device activates the ambient light, it also includes adjusting the brightness of the ambient light based on the operating speed of the rapid cooling fan when the refrigerator door is open. The brightness of the ambient light is directly proportional to the operating speed of the rapid cooling fan.

[0167] Thus, when the refrigerator door is opened, this embodiment of the disclosure provides the user with an intuitive and dynamic visual feedback by adjusting the brightness of the ambient light. When the rapid cooling fan is running at high speed, the brightness of the ambient light increases accordingly, intuitively demonstrating to the user that the system is performing powerful cooling. This makes the previously invisible rapid cooling process visible, improving the user experience and the friendliness of human-computer interaction.

[0168] Optionally, after the control device starts the ambient light, it also includes: when the refrigerator door is closed, the control device controls the ambient light to turn off.

[0169] In this way, when the refrigerator door is closed, the user cannot see the ambient light. Turning off the light at this time saves energy and conforms to the user's usage logic. Therefore, the embodiments of this disclosure can directly turn off the ambient light to achieve on-demand control of the ambient light.

[0170] Optionally, combined Figure 4 and 7 As shown, the ambient light can be installed inside the rapid cooling component. In this case, the lighting module 300 of the rapid cooling component is equivalent to the ambient light.

[0171] In this way, the embodiments of the present disclosure can adopt the form of setting the lighting module above and setting the air guide slope below in the air delivery section of the air duct of the rapid cooling component. This not only makes the air guide slope present a luminous effect, but also, under the constraint of the air delivery section, the light emitted by the lighting module can only illuminate the air guide slope. This further reduces or avoids the situation where the lighting module leaks light to other positions, and improves the display effect of the rapid cooling component and the refrigerator.

[0172] Based on the above refrigerator, combined with Figure 10 As shown in the embodiments of this disclosure, another control method for a refrigerator is provided, including:

[0173] S201, when the refrigerator door is detected to be opening or closing, the control device controls the temperature sensor to continuously monitor the temperature in the rapid cooling compartment.

[0174] S202, when the temperature in the rapid cooling space meets the conditions for placing the heat source, the control device controls the rapid cooling fan to start running, so as to guide the cold air to cool the heat source in the rapid cooling space.

[0175] S203, when the temperature in the rapid cooling space meets the conditions for heat source frost, the control device controls the rapid cooling fan to operate intermittently to avoid heat source frost in the rapid cooling space.

[0176] The refrigerator control method provided in this disclosure controls the rapid cooling fan to operate intermittently when the temperature in the rapid cooling space meets the conditions for heat source frost, thereby preventing heat source frost. Thus, this disclosure effectively avoids the risk of frost formation caused by excessive cooling while ensuring rapid cooling. Through brief fan pauses, this disclosure allows the local temperature on or around the heat source surface to rise moderately, effectively preventing water vapor condensation into frost or water droplets, avoiding damage to food quality, and maintaining a hygienic environment inside the refrigerator. This intelligent, dynamic antifreeze control achieves a "soft landing" during rapid cooling, balancing cooling efficiency and food safety.

[0177] Optionally, the conditions for placing the heat source include: the temperature in the rapid cooling space is greater than or equal to the preset start-up temperature; and the temperature change rate in the rapid cooling space is greater than or equal to the preset temperature change rate.

[0178] In this way, the embodiments of this disclosure can use the temperature and temperature change rate in the rapid cooling space to determine the conditions for placing a heat source, overcoming the misjudgment defects caused by single-dimensional judgment, thereby accurately identifying the real heat source placement event, effectively eliminating false triggering caused by human hand taking things or heat source being taken out before closing the door, improving the accuracy and reliability of the rapid cooling function, and thus avoiding energy waste caused by misjudgment.

[0179] Optionally, the temperature within the rapid cooling space includes the heat source temperature and the ambient temperature; the heat source frost conditions include: the ambient temperature within the rapid cooling space is less than or equal to the first frost temperature; and / or, the heat source temperature within the rapid cooling space is less than or equal to the second frost temperature.

[0180] Thus, this embodiment incorporates the ambient temperature and / or heat source temperature within the rapid cooling space into the frost determination, thereby enabling a more accurate grasp of frost risk points and ensuring that the rapid cooling fan only starts intermittent operation when there is a risk of frost, achieving refined anti-freeze control.

[0181] Optionally, the first frost temperature can be set in conjunction with the internal refrigeration temperature. For example, the first frost temperature can be set to 0°C to more accurately identify frost risk points, thereby achieving refined anti-freeze control. The first frost temperature can also be adjusted according to the user's actual needs or set to any other reasonable value.

[0182] Optionally, the second frost temperature can be set in conjunction with the internal refrigeration temperature. For example, the second frost temperature can be set to 2°C to more accurately identify frost risk points, thereby achieving refined anti-freeze control. The second frost temperature can also be adjusted according to the user's actual needs or set to any other reasonable value.

[0183] Optionally, the control device controls the rapid cooling fan to operate intermittently, including: the control device cyclically executing the following steps until the temperature in the rapid cooling space does not meet the frost conditions of the heat source: the control device controls the rapid cooling fan to start running for a first duration; the control device controls the rapid cooling fan to stop running for a second duration.

[0184] Thus, the embodiments of this disclosure can control the rapid cooling fan to alternate between a first running period and a second running period, thereby achieving intermittent operation. This allows the local temperature to rise briefly by stopping the air supply while continuously cooling the heat source, effectively preventing frost formation.

[0185] Optionally, the initial cooling time can be set in conjunction with the internal refrigeration temperature. For example, the initial cooling time can be set to 1 minute to ensure rapid cooling and thus improve food storage performance. The initial cooling time can also be adjusted according to the user's actual needs or set to any other reasonable value.

[0186] Optionally, the second duration can be set in conjunction with the internal refrigeration temperature. For example, the second duration can be set to 1 minute to allow the local temperature to rise, thereby effectively preventing frost formation. The second duration can also be adjusted according to the user's actual needs or set to any other reasonable value.

[0187] Optionally, the control device cyclically executes the following steps until the temperature in the rapid cooling space does not meet the frost conditions of the heat source, further including: the control device determining the heat source information in the rapid cooling space; the control device determining a first duration and a second duration based on the heat source information in the rapid cooling space.

[0188] Thus, in this embodiment of the present disclosure, before executing intermittent operation, the heat source information within the rapid cooling space is determined, and a first duration and a second duration are determined based on this information. This embodiment of the present disclosure can transform the control of intermittent operation from a fixed timing sequence to dynamic adaptation. By analyzing the specific information of the heat source, the system can configure the optimal intermittent cycle for different types of heat sources, such as extending the operating time for high-temperature heat sources or low-humidity heat sources, thereby effectively achieving rapid cooling while precisely controlling the frost prevention rhythm, improving the overall efficiency and accuracy of the solution.

[0189] Optionally, the heat source information within the rapid cooling space includes the heat source temperature; the control device determines a first duration and a second duration based on the heat source information within the rapid cooling space, including: when the heat source temperature within the rapid cooling space is greater than or equal to a preset heat source temperature, the control device determines the first duration to be T. 11 The second duration is determined to be T. 21 Alternatively, if the heat source temperature in the rapid cooling space is lower than the preset heat source temperature, the control device determines the first duration to be T. 12 The second duration is determined to be T. 22 Among them, T 11 +T 21 =T 12 +T 22 T 11 / T 21 >T 12 / T 22 .

[0190] Thus, when the heat source temperature is high, this embodiment of the disclosure will allocate a larger run / stop time ratio (T). 11 / T 21This ensures that while preventing frost, it can provide a more continuous and powerful cooling output, thereby improving rapid cooling efficiency. This ensures that the control strategy can be matched with the actual cooling needs of the heat source, achieving a balance between efficiency and effectiveness.

[0191] Optionally, the heat source information within the rapid cooling space includes heat source humidity; the control device determines a first duration and a second duration based on the heat source information within the rapid cooling space, including: when the heat source humidity within the rapid cooling space is greater than or equal to a preset heat source humidity, the control device determines the first duration as T. 13 The second duration is determined to be T. 23 Alternatively, if the humidity of the heat source in the rapid cooling space is lower than the preset humidity of the heat source, the control device determines the first duration to be T. 14 The second duration is determined to be T. 24 Among them, T 13 +T 23 =T 14 +T 24 T 13 / T 23 <T 14 / T 24 .

[0192] Thus, when the heat source has high humidity, it is more prone to generating water vapor and frost due to its high water content. Therefore, this embodiment of the solution allocates a smaller run / stop time ratio (T) to it. 13 / T 23 This means that the fans will stop more frequently, effectively preventing water vapor from condensing into frost at the source. This ensures that the anti-frost strategy directly addresses the root cause of frost formation, providing efficient and energy-saving anti-freeze protection.

[0193] Optionally, the control method further includes: when the temperature in the rapid cooling space meets the frost conditions of the heat source, the control device obtains the continuous frost duration; when the continuous frost duration is greater than or equal to the preset frost duration, the control device controls the rapid cooling fan to stop running, so as to stop guiding the cold air to cool the heat source in the rapid cooling space.

[0194] Thus, this embodiment of the present disclosure can further determine the duration of continuous frost when there is a risk of frost, thereby forming a double insurance mechanism. If the frost problem cannot be solved by intermittently running the rapid cooling fan for a period of time, the system will forcibly stop the rapid cooling fan to ensure food safety to the greatest extent and prevent the risk of freezing damage in extreme cases.

[0195] Optionally, the preset frost duration can be set in conjunction with the internal refrigeration temperature. For example, the preset frost duration can be set to 10 minutes to determine if intermittent operation can solve the frost problem, thereby preventing the risk of freezing damage in extreme cases. The preset frost duration can also be adjusted according to the user's actual needs or set to any other reasonable value.

[0196] Optionally, the control method further includes: when the temperature in the rapid cooling space meets the conditions for the heat source to reach the required temperature, the control device controls the rapid cooling fan to stop operating, so as to stop guiding the cold air to cool the heat source in the rapid cooling space.

[0197] Thus, this embodiment of the present disclosure can be combined with the heat source temperature conditions to ensure that the function is deactivated in a timely manner after rapid cooling is completed, thereby avoiding waste of cooling capacity and preventing the fan from running at high load for a long time.

[0198] Optionally, the temperature within the rapid cooling space includes the heat source temperature and the ambient temperature; the conditions for the heat source to reach the desired temperature include: the heat source temperature within the rapid cooling space is less than or equal to the preset shutdown temperature; and / or, the difference between the heat source temperature and the ambient temperature within the rapid cooling space is less than or equal to the preset temperature difference; and / or, the continuous operating time of the rapid cooling fan is greater than or equal to the preset operating time.

[0199] In this way, the embodiments of this disclosure can use a combination of various heat source temperature conditions for judgment, including whether the temperature of the heat source in the rapid cooling space is low, whether the temperature difference between the heat source temperature and the ambient temperature is small, and whether the continuous running time of the fan is long, etc., thereby providing multiple and flexible judgment criteria for the precise shutdown of the rapid cooling function, which can not only ensure that the heat source is sufficiently cooled, but also stop the operation in time, avoid over-cooling, and ensure energy efficiency.

[0200] Based on the above refrigerator, combined with Figure 11 As shown in the embodiments of this disclosure, another control method for a refrigerator is provided, including:

[0201] S301, when the refrigerator door is detected to be opening or closing, the control device controls the temperature sensor to continuously monitor the temperature in the rapid cooling compartment.

[0202] S302, when the temperature in the rapid cooling space meets the conditions for placing a heat source, the control device determines the heat source information in the rapid cooling space.

[0203] S303, the control device controls the rapid cooling fan to start and run according to the heat source information in the rapid cooling space, so as to guide the cold air to cool the heat source in the rapid cooling space.

[0204] The refrigerator control method provided in this disclosure, when the temperature within the rapid cooling space meets the conditions for placing a heat source, further determines the specific heat source information and controls the operation of the rapid cooling fan based on this information. Thus, this disclosure elevates rapid cooling control from a coarse judgment of "whether a heat source is present" to a refined analysis of "what the heat source is." By identifying the specific attributes of the heat source, this disclosure can move away from a "one-size-fits-all" airflow mode and instead provide personalized and refined effective airflow based on actual needs. This allows cooling resources to be accurately and on-demanded to specific targets, fundamentally solving the problem of unreasonable cooling distribution, greatly improving refrigeration efficiency, and achieving significant energy-saving effects.

[0205] Optionally, the heat source information in the rapid cooling space includes the number of heat sources; the control device controls the rapid cooling fan to start operation based on the heat source information in the rapid cooling space, including: when there is only one heat source in the rapid cooling space, the control device controls the rapid cooling fan to start operation in a directional airflow mode; when there are multiple heat sources in the rapid cooling space, the control device controls the rapid cooling fan to start operation in a variable airflow mode.

[0206] Thus, the embodiments of this disclosure can adjust the specific air outlet mode of the rapid cooling fan based on the number of detected heat sources. When there is only one heat source in the rapid cooling space, a directional air outlet mode is adopted, while when there are multiple heat sources in the rapid cooling space at the same time, a variable air outlet mode is adopted. This allows the selection of the best air supply strategy according to the specific scenario, enabling efficient centralized cooling of a single heat source and coordinated cooling of multiple heat sources, which greatly improves the cooling efficiency and cooling capacity utilization.

[0207] Optionally, the heat source information within the rapid cooling space also includes the location of the heat source; the control device controls the rapid cooling fan to start operation in a directional airflow manner, including: the control device determines the target working angle toward the heat source based on the location of the heat source; the control device controls the rapid cooling fan to start operation and continuously delivers cold air according to the target working angle.

[0208] In this way, the embodiments of this disclosure control the target working angle of the rapid cooling fan by determining the location of the heat source, so that the cold air can be accurately and directionally delivered to the location of the heat source, avoiding unnecessary diffusion of cold energy, and realizing the true meaning of "wherever the heat source is, the cold air blows there", which significantly improves the cooling effect.

[0209] Optionally, the heat source information within the rapid cooling space also includes the size of the heat source; the control device controls the rapid cooling fan to start and operate, and continuously delivers cold air according to the target working angle, including: the control device determines the target working speed corresponding to the heat source based on the size of the heat source; the control device controls the rapid cooling fan to start and operate, and continuously delivers cold air according to the target working angle and the target working speed.

[0210] Thus, the embodiments of this disclosure can further determine the target operating speed of the fan according to the size of the heat source, realizing on-demand matching of cooling intensity. It provides stronger airflow for large-sized heat sources and correspondingly reduces airflow for small-sized heat sources, achieving energy saving and noise reduction while ensuring the cooling effect.

[0211] Optionally, the control device determines the target operating speed corresponding to the heat source based on the heat source size, including: when the heat source size is greater than or equal to a first preset size, the control device outputs a first speed command to make the rapid cooling fan operate at a high speed; or, when the heat source size is less than the first preset size but greater than or equal to a second preset size, the control device outputs a second speed command to make the rapid cooling fan operate at a medium speed; or, when the heat source size is less than the second preset size, the control device outputs a third speed command to make the rapid cooling fan operate at a low speed.

[0212] Thus, this embodiment of the present disclosure can determine and adjust the operating speed of the rapid cooling fan in stages according to the size of the heat source in the rapid cooling space, so as to achieve on-demand matching of rapid cooling intensity. For large heat sources, the system can automatically provide high-speed and powerful airflow to ensure rapid cooling; for small heat sources, it operates at low speed, thereby avoiding unnecessary energy waste and overcooling. This gradient intelligent control ensures precise correspondence between cooling output and heat load, significantly improving cooling efficiency and energy utilization.

[0213] Optionally, the heat source information in the rapid cooling space also includes the heat source positions corresponding to each of the multiple heat sources; the control device controls the rapid cooling fan to start operation in a variable air outlet mode, including: the control device determines multiple target working angles facing the multiple heat sources according to the heat source positions corresponding to each of the multiple heat sources; the control device controls the rapid cooling fan to start operation and alternately delivers cold air according to the multiple target working angles.

[0214] In this way, for situations where multiple heat sources exist simultaneously in a rapid cooling space, the embodiments of this disclosure can control the rapid cooling fan by determining multiple target working angles and alternately delivering cold air, so as to ensure that each heat source can be cooled in a timely manner, avoid cooling blind spots, and improve the user experience in scenarios where multiple items are stored.

[0215] Optionally, the heat source information within the rapid cooling space also includes the heat source dimensions corresponding to each of the multiple heat sources; the control device controls the rapid cooling fan to start operation and alternately deliver cold air according to multiple target working angles, including: the control device determines multiple target working durations and / or target working speeds corresponding to the multiple heat sources based on the heat source dimensions corresponding to each of the multiple heat sources; the control device controls the rapid cooling fan to start operation and alternately delivers cold air according to the target working angle, target working duration, and / or target working speed corresponding to each of the multiple heat sources.

[0216] Thus, the embodiments of this disclosure also determine the target operating time and / or target operating speed of each of the multiple heat sources according to their size, thereby realizing personalized and precise cooling of multiple heat sources, ensuring that the allocation of cooling resources matches the actual heat load of each heat source, and significantly improving the uniformity of rapid cooling and energy efficiency.

[0217] Optionally, the control device determines multiple target operating durations and / or target operating speeds corresponding to the multiple heat sources based on their respective heat source sizes. This includes: when the heat source size is greater than or equal to a first preset size, the control device outputs a first speed command and / or a first air supply duration; or, when the heat source size is less than the first preset size but greater than or equal to a second preset size, the control device outputs a second speed command and / or a second air supply duration; or, when the heat source size is less than the second preset size, the control device outputs a third speed command and / or a third air supply duration. Wherein, the first air supply duration is longer than the second air supply duration, and the second air supply duration is longer than the third air supply duration.

[0218] Thus, this embodiment of the disclosure can determine and adjust the target operating time and / or target operating speed for each heat source in a graded manner according to the size of each heat source, thereby achieving personalized and precise matching of cooling control for multiple heat sources. This embodiment of the disclosure can allocate the most suitable cooling intensity and airflow time to each heat source based on its size; for example, providing a stronger airflow and / or a longer airflow duration for larger heat sources, while correspondingly reducing the airflow and / or airflow duration for smaller heat sources. This ensures that cooling resources can be accurately and fairly allocated to each target, fundamentally solving the problem of inefficient cooling allocation in multi-heat-source scenarios and significantly improving overall cooling efficiency and energy utilization.

[0219] Optionally, there are multiple rapid cooling fans, each used to deliver cold air to multiple sub-areas within the rapid cooling space; the control device controls the rapid cooling fans to start operation based on heat source information within the rapid cooling space, so as to guide the cold air to cool the heat source within the rapid cooling space, including: the control device determines the target rapid cooling fan corresponding to the heat source based on the heat source information within the rapid cooling space; the control device controls the target rapid cooling fan to start operation, so as to guide the cold air to cool the heat source in the sub-area corresponding to the target rapid cooling fan.

[0220] Thus, the embodiments of this disclosure can achieve zoned rapid cooling through multiple rapid cooling fans, which can independently provide cold air to different sub-areas, achieving true regionalized rapid cooling and meeting the needs of complex storage layouts.

[0221] Optionally, the heat source information within the rapid cooling space also includes the location of the heat source; the control device determines the target rapid cooling fan corresponding to the heat source based on the heat source information within the rapid cooling space, including: the control device determines the target sub-region where the heat source is located based on the location of the heat source; the control device identifies the rapid cooling fan that delivers cold air to the target sub-region as the target rapid cooling fan.

[0222] In this way, the embodiments of this disclosure can determine the sub-region where the heat source is located based on the location of the heat source within the rapid cooling space, and then identify the rapid cooling fan that delivers cold air to that sub-region as the target rapid cooling fan, thereby concentrating the cooling energy on the area surrounding the heat source to achieve directional cooling. The embodiments of this disclosure avoid ineffective air delivery to non-target areas, reduce overall energy consumption, and improve cold air utilization and cooling efficiency, enabling the heat source to reach the set preservation temperature in the shortest possible time. Even when the heat source distribution is uneven or there are many heat sources, the mapping relationship between the sub-region and the rapid cooling fan can still maintain uniform and rapid cooling coverage, significantly improving the problems of dispersed cooling energy, slow temperature drop, and low energy efficiency under traditional overall air delivery methods.

[0223] Based on the above refrigerator, combined with Figure 12 As shown in the embodiments of this disclosure, another control method for a refrigerator is provided, including:

[0224] S401, when the refrigerator is powered on and running, the control device obtains the predicted time point when the user will store the heat source and the current time point.

[0225] S402, if the predicted time point and the current time point meet the pre-cooling time condition, the control device controls the temperature sensor to continuously detect the temperature in the rapid cooling space.

[0226] S403, when the temperature in the rapid cooling space meets the pre-cooling temperature conditions, the control device controls the rapid cooling fan to start before the predicted time point in order to pre-cool the rapid cooling space.

[0227] The control method for a refrigerator provided in this disclosure, when the refrigerator is powered on and running, acquires the predicted time point when a user places a heat source inside, and controls the rapid cooling fan to pre-start before that time point when specific conditions are met. Thus, this disclosure upgrades the traditional "passive response" rapid cooling mode to an "active predictive" pre-cooling mode. By analyzing and predicting user behavior, this disclosure can pre-cool the rapid cooling space before the user places the heat source inside. This fundamentally eliminates the startup lag caused by passive response, ensuring sufficient cold energy reserve when the heat source is placed inside, thereby significantly improving rapid cooling efficiency and greatly optimizing the user experience.

[0228] Optionally, the control device obtains the predicted time point of the user storing heat source, including: the control device constructs a storage time prediction model based on the historical time information of the user storing heat source; the control device determines the predicted time point of the user storing heat source on the current day based on the storage time prediction model.

[0229] Thus, embodiments of this disclosure can utilize historical time information of user-stored heat sources to construct a storage time prediction model, and then analyze the predicted time points when the user may store heat sources next. Based on this, embodiments of this disclosure can provide key self-learning capabilities for the pre-cooling function, enabling the refrigerator to intelligently recognize and learn the user's living habits, thereby achieving accurate prediction and advance preparation, and avoiding unnecessary pre-cooling operations.

[0230] Optionally, the pre-cooling time condition includes: the time difference between the predicted time point and the current time point is less than or equal to the pre-cooling start-up time.

[0231] In this way, the embodiments of this disclosure can meet the pre-cooling time conditions by setting the time difference between the predicted time point and the current time point, thereby ensuring that the pre-cooling function is started within the optimal time window. This avoids energy waste caused by starting too early and ensures sufficient pre-cooling time, thus achieving a perfect balance between energy efficiency and effect.

[0232] Optionally, the pre-cooling start-up time can be set in conjunction with the internal refrigeration temperature. For example, the pre-cooling start-up time can be set to 1 minute to ensure that the pre-cooling function starts within the optimal time window, thereby achieving a balance between energy efficiency and performance. The pre-cooling start-up time can also be adjusted according to the user's actual needs or set to any other reasonable value.

[0233] Optionally, the pre-cooling temperature conditions include: the temperature in the rapid cooling space is greater than or equal to the pre-cooling start temperature; and / or, the temperature difference between the rapid cooling space and the temperature inside the cold storage room is greater than or equal to the pre-cooling start temperature difference.

[0234] Thus, this embodiment provides specific criteria for judging pre-cooling temperature conditions, ensuring that the rapid cooling fan is only activated when pre-cooling is required (such as when the temperature of the rapid cooling space is too high or the temperature difference with the main cold storage room is large), further avoiding unnecessary energy consumption.

[0235] Optionally, the pre-cooling start temperature can be set in conjunction with the internal refrigeration temperature. For example, the pre-cooling start temperature can be set to 10°C to ensure that the rapid cooling fan only starts when pre-cooling is needed, avoiding unnecessary energy consumption. The pre-cooling start temperature can also be adjusted according to the user's actual needs or set to any other reasonable value.

[0236] Optionally, the pre-cooling start-up temperature difference can be set in conjunction with the internal refrigeration temperature. For example, the pre-cooling start-up temperature difference can be set to 2°C to ensure that the rapid cooling fan only starts when pre-cooling is needed, avoiding unnecessary energy consumption. The pre-cooling start-up temperature difference can also be adjusted according to the user's actual needs or set to any other reasonable value.

[0237] Optionally, the control device controls the rapid cooling fan to pre-start before the predicted time point, including: the control device predicts the target heat source information stored by the user; the control device determines the target pre-cooling parameters of the rapid cooling fan based on the target heat source information; and the control device controls the rapid cooling fan to pre-start before the predicted time point according to the target pre-cooling parameters.

[0238] In this way, the embodiments of this disclosure can increase the prediction of target heat source information and determine the parameters of the fast cooling fan that are suitable for it. This makes the pre-cooling function not only to deliver air in advance, but also to prepare the most suitable pre-cooling strategy in advance based on the prediction of future heat sources (such as type, size, and location), thus realizing a more intelligent and personalized pre-cooling experience.

[0239] Optionally, the control device predicts the target heat source information for the user's stored heat source, including: the control device constructs a heat source information prediction model based on the user's historical stored heat source information; and determines the target heat source information for the user's stored heat source on the current day based on the heat source information prediction model.

[0240] Thus, this embodiment of the disclosure can utilize historical heat source information stored by the user to construct a heat source information prediction model, thereby determining the target heat source information that the user may store on a given day. This embodiment of the disclosure can upgrade the single-dimensional "time prediction" to a multi-dimensional "heat source information prediction." By knowing the potential type, size, quantity, location, temperature, humidity, and other information of the heat source before pre-cooling starts, the system can adjust pre-cooling parameters in advance according to the characteristics of the heat source, such as preset airflow and direction, thereby achieving a more personalized and precise pre-cooling operation. This ensures that the refrigerator is ready with the most suitable cooling conditions when the heat source is placed in, significantly improving pre-cooling efficiency and energy efficiency ratio.

[0241] Optionally, the target heat source information includes the target heat source type; the control device determines the target pre-cooling parameters of the rapid cooling fan based on the target heat source information, including: when the target heat source type is a hot pot, determining the target pre-cooling parameters of the rapid cooling fan to include a first pre-cooling duration and / or a first pre-cooling speed; or, when the target heat source type is a beverage, determining the target pre-cooling parameters of the rapid cooling fan to include a second pre-cooling duration and / or a second pre-cooling speed. Wherein, the first pre-cooling duration is greater than the second pre-cooling duration, and the first pre-cooling speed is greater than the second pre-cooling speed.

[0242] In this way, embodiments of the present disclosure can dynamically determine the target pre-cooling duration and / or target pre-cooling speed of the rapid cooling fan based on the type of target heat source (such as a hot pot or beverage), upgrading pre-cooling control from a single-dimensional "time prediction" to a more insightful "heat source information prediction." For example, if it is predicted that a user will store a high-heat-load item such as a hot pot, embodiments of the present disclosure can start the rapid cooling fan in advance and pre-cool it at a higher speed or for a longer time to store sufficient cold capacity. Conversely, if it is predicted that a user will store a relatively low-heat-load item such as a beverage, a lower speed or shorter duration of pre-cooling can be used. This ensures that the pre-cooling operation directly affects the actual heat load of the heat source, fundamentally improving pre-cooling efficiency and energy efficiency ratio, and achieving a more precise and personalized refrigeration service.

[0243] Optionally, after determining the target precooling parameters of the rapid cooling fan based on the target heat source information, the control device further includes: adjusting the target precooling parameters of the rapid cooling fan based on the storage information of the cold storage room.

[0244] Thus, after determining the target pre-cooling parameters of the rapid-cooling fan based on the target heat source information, this embodiment of the present disclosure can also adaptively modify these parameters based on the storage information of the refrigerator compartment. By taking the storage capacity of the refrigerator compartment into account, this embodiment of the present disclosure can more intelligently assess the overall heat load and dynamically modify the pre-cooling parameters accordingly, ensuring that the pre-cooling effect can both meet the requirements of rapid response to new heat sources and be coordinated with the current operating state of the refrigerator, thereby improving the reliability and energy efficiency of the control.

[0245] Optionally, the control device adjusts the target pre-cooling parameter of the rapid cooling fan based on the storage information of the cold storage compartment, including: increasing the target pre-cooling parameter of the rapid cooling fan when the storage ratio of the cold storage compartment is greater than or equal to a first preset ratio; or maintaining the target pre-cooling parameter of the rapid cooling fan when the storage ratio of the cold storage compartment is less than the first preset ratio but greater than a second preset ratio; or decreasing the target pre-cooling parameter of the rapid cooling fan when the storage ratio of the cold storage compartment is less than or equal to the second preset ratio. Wherein, the first preset ratio is greater than the second preset ratio.

[0246] In this way, the embodiments of this disclosure can divide the storage ratio of the cold storage compartment into different ranges, and adjust the target pre-cooling parameters of the rapid cooling fan accordingly to achieve dynamic adaptation of the pre-cooling intensity. When the storage ratio of the cold storage compartment is high, the embodiments of this disclosure can increase the target pre-cooling parameters to compensate for the high heat load and ensure rapid cooling effect; while when the storage ratio is low, the embodiments of this disclosure will decrease the target pre-cooling parameters to avoid unnecessary energy consumption. This graded adjustment method makes the pre-cooling strategy more precise and achieves an effective balance between energy efficiency and cooling effect.

[0247] Optionally, the control method further includes: when the temperature in the rapid cooling space does not meet the pre-cooling temperature conditions, the control device controls the rapid cooling fan to stop running; when the refrigerator door is detected to be opening or closing, the control device controls the temperature sensor to continuously detect the temperature in the rapid cooling space; and the control device controls the operating status of the rapid cooling fan according to the temperature in the rapid cooling space.

[0248] In this way, when the temperature inside the rapid cooling space does not meet the pre-cooling temperature requirements, the rapid cooling fan stops operating, avoiding energy waste. Simultaneously, the combination of door opening / closing actions and temperature feedback achieves seamless integration of the rapid cooling function, making the pre-cooling and real-time rapid cooling functions complementary, ensuring a consistent user experience and system stability.
