[0002] At present, with the improvement of the living standards of residents, the refrigerator has become an indispensable electrical appliance in the family. The refrigeration control mode of the traditional refrigerator is mostly based on the adjustment of the overall temperature of the refrigeration chamber, that is, the cold quantity is output through the main air duct and the evaporator to maintain the refrigeration chamber in the fixed temperature range set by the user. However, in the actual use process, the user often directly puts the hot dishes, hot soup or high-temperature containers of large volume into the refrigeration chamber. Such high-temperature objects will significantly disturb the temperature distribution of the refrigeration chamber, causing insufficient cold quantity and local high temperature, and then affecting the food preservation effect. In view of this demand, the related technology proposes a refrigerator product which sets up an independent drawer or chamber and allows the user to manually set an independent preservation temperature.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0004] The related technology is prone to overcooling problems in the long-time rapid cooling process, especially when the heat source temperature rapidly decreases, if the forced air supply is still continued, it is easy to cause frost or freezing on the surface of the heat source, affecting the taste and storage quality of the food.

[0005] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

DETAILED DESCRIPTION

[0031] In order to enable a more detailed understanding of the features and technical content of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure is described in detail below, and the attached drawings are only used for reference and do not limit the embodiments of the present disclosure. In the following technical description, in order to facilitate explanation, through multiple details, a sufficient understanding of the disclosed embodiments is provided. However, one or more embodiments can still be implemented without these details. In other cases, in order to simplify the drawings, well-known structures and devices can be simplified.

[0032] The terms "first", "second", and the like in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0033] Unless otherwise specified, the term "a plurality of" means two or more.

[0034] In the embodiments of the present disclosure, the character " / " represents an "or" relationship between the objects before and after it. For example, A / B means A or B.

[0035] The term "and / or" is a descriptive term that refers to an association relationship, which means that there can be three relationships. For example, A and / or B means that there are three relationships of A or B, or A and B.

[0036] The term "corresponding" can refer to an association relationship or a binding relationship. A corresponds to B means that there is an association relationship or a binding relationship between A and B.

[0037] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0038] During the use of the refrigerator, there is a demand for rapid cooling of high-temperature food or rapid cooling of normal-temperature food. Some refrigerators have a rapid cooling function. For example, a refrigerator is disclosed in the related art, which specifically comprises: a rapid cooling drawer, which is arranged in a refrigeration rapid cooling chamber, and is provided with a heat preservation sealing cover plate on the upper surface, a refrigeration tank air duct partition plate on the lower surface, a refrigerator freezing tank on the left side surface, a fruit and vegetable box chamber partition plate on the right side surface, and a back plate on the back surface; a rubber strip for sealing is arranged on the cover plate of the rapid cooling drawer; an independent refrigeration pipeline is arranged on one side of the rapid cooling drawer and connected with a refrigerator refrigeration air outlet; and an independent air door is arranged on the independent refrigeration pipeline and connected with a refrigerator control panel. The refrigerator can realize the effect of rapid refrigeration of cooling the product to be rapidly cooled to the required temperature in a short time through the cooperation of the rapid cooling drawer, the independent refrigeration pipeline and the independent air door in the refrigeration rapid cooling chamber. The problem of the related art is that the independent refrigeration pipeline is arranged in the drawer, which not only needs to arrange additional accessory components, but also causes energy loss of the cold air in the independent refrigeration pipeline, affecting the rapid cooling effect on the rapid cooling object.

[0039] In order to improve the cooling effect on the rapid cooling object, in combination with Figures 1-8 As shown in the figure, the present disclosure provides a rapid cooling assembly 20 for a refrigeration device, which comprises an air guide structure 101 and a circulating fan 200. The air guide structure 101 comprises a shell 100, the inside of the shell 100 defines an air guide duct 140, the shell 100 is provided with an air inlet opening near the first end of the shell 100, the air inlet opening is adapted to be open to the cold air forming position of the refrigeration device, and the shell 100 is provided with an air outlet opening 148 near the other end of the shell 100; the circulating fan 200 is arranged in the shell 100, and the fan inhales air from the air inlet opening and sends out air from the air outlet opening when the fan operates to reduce the temperature of the rapid cooling object.

[0040] In the present disclosure, the refrigeration device includes a refrigerator, a refrigerator cabinet and a display cabinet, etc., which can create a low-temperature storage environment to prolong the shelf life of food and medicine.

[0041] In the embodiments of the present disclosure, the air inlet of the air guide duct is the air inlet end of the air guide duct 140, and the air outlet of the air guide duct is the air outlet end of the air guide duct 140.

[0042] The cold air forming position of the refrigeration equipment refers to a position where cold air is formed or blown, and the temperature of the cold air is lower than that of the refrigeration space 12. For the air-cooled refrigerator, the cold air forming position is the air outlet of the refrigeration space 12; for the direct-cooled refrigerator, the cold air forming position is the position of the refrigeration space 12 close to the evaporator.

[0043] The open docking is opposite to the traditional closed docking. If the air inlet end of the air guide duct 140 is in closed docking with the air outlet of the refrigeration space 12, and the air of the refrigeration space 12 is excluded from entering the air inlet of the air guide duct 140, the air inlet end of the air guide duct 140 is in closed docking with the air outlet of the refrigeration space 12. Conversely, the air inlet end of the air guide duct 140 is close to the cold air forming position of the refrigeration equipment, and the air of the refrigeration space 12 is not excluded or limited from entering the air guide duct 140 from the air inlet end, so the air inlet end of the air guide duct 140 is in the form of open docking with the air outlet of the refrigeration space 12. For example, in the case of the refrigerator being an air-cooled refrigerator, the refrigerator defines a refrigeration space and is provided with a refrigeration air outlet, the air inlet end of the air guide duct is spaced apart from the refrigeration air outlet of the refrigeration chamber, cold air enters the refrigeration space through the refrigeration air outlet, and then enters the air guide duct of the rapid cooling assembly through the air inlet, and then enters the refrigeration space again through the air outlet of the rapid cooling assembly.

[0044] In the embodiments of the present disclosure, the rapid cooling assembly 20 can be assembled into the refrigeration space 12 as an independent component. The shell 100 of the rapid cooling assembly 20 defines the air guide duct 140, and the circulating fan 200 of the rapid cooling assembly 20 is arranged in the air guide duct 140. The air inlet of the rapid cooling assembly 20 is in open docking with the refrigeration air outlet 14. In the case that the circulating fan 200 is not started, the refrigeration air outlet 14 normally discharges air to uniformly reduce the temperature of the refrigeration space 12. In the case that the circulating fan 200 is started, the air inlet of the rapid cooling assembly 20 sucks the cold air blown out of the refrigeration air outlet 14, and blows the cold air to the rapid cooling object in the refrigeration space 12 after being pressurized by the circulating fan 200. When the circulating fan 200 operates, the flow rate of the cold air blown to the rapid cooling object increases, and the flow rate increases, so that the temperature of the rapid cooling object can be reduced more quickly.

[0045] It should be noted that although a part of the air of the refrigeration space 12 can enter the air guide duct 140 through the air inlet of the air guide duct 140, since the air inlet is located close to the refrigeration air outlet 14, the air entering the air guide duct 140 is still mainly the air blown out of the refrigeration air outlet 14, and therefore the temperature of the air entering the air guide duct 140 is still low as a whole.

[0046] The cooling of the rapid cooling object is mainly in the form of heat convection, and the efficiency of the cooling depends on the temperature difference between the cold air and the rapid cooling object, and the flow rate and flow volume of the cold air. In the case that the circulating fan 200 is started, the flow rate and flow volume of the cold air can be significantly increased, and the heat convection heat exchange effect of the rapid cooling object is improved, thereby improving the cooling speed of the rapid cooling object.

[0047] Compared with the form of "closed docking", the form of open docking has smaller loss of air volume in the air guide duct 140 due to the shorter overall pipeline of the air guide duct 140, and under the condition that the power of the circulating fan 200 is constant, the rapid cooling assembly 20 can perform heat convection heat exchange with the rapid cooling object at a higher flow rate and a larger flow volume.

[0048] Compared with the form in which only the circulating fan 200 directly blows the rapid cooling object, the air inlet end of the air guide duct 140 is open docked with the refrigeration air outlet 14, more cold air blown by the refrigeration air outlet 14 is sucked through the air guide opening, and the cold air blown by the rapid cooling assembly 20 has a lower temperature, so that the temperature of the rapid cooling object can be lowered faster.

[0049] Compared with the form in which a separate air duct is provided, the rapid cooling assembly 20 provided in the embodiment of the present disclosure does not affect the normal refrigeration of the refrigeration air outlet 14 when the circulating fan 200 is not working. In addition, the rapid cooling assembly 20 can be installed to the inner wall of the refrigeration space 12 and does not need to be embedded in the foaming layer, so that the air duct structure of the refrigeration equipment is simple, and the manufacturing cost of the refrigeration equipment is low.

[0050] When the temperature of the rapid cooling object is lowered, the flow rate, flow volume and temperature of the cold air blown to the rapid cooling object can be improved by using the rapid cooling assembly 20 disclosed in the present application, so that the heat convection heat exchange effect of the rapid cooling object is improved, and the cooling rate of the rapid cooling object is improved. In addition, the form in which the air guide duct 140 of the rapid cooling assembly 20 is open docked with the refrigeration chamber can reduce the cost increase caused by the setting of an additional air duct, and reduce the effect of the rapid cooling assembly 20 on the normal refrigeration of the refrigeration space 12 of the refrigeration equipment when the circulating fan 200 is not started.

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

[0052] In the embodiments of the present disclosure, the "length direction", "height direction" and "thickness direction" are all in the use state of the rapid cooling assembly 20: the refrigeration equipment is a front-opening refrigerator, and when a user faces the refrigerator, the up-down direction of the user is the height direction, the front-rear direction of the user is the depth direction, and the left-right direction of the user is the thickness direction. However, this form of expression does not strictly limit the use mode of the rapid cooling assembly 20. For example, in some cases, the rapid cooling assembly 20 can be in a use form in which the length direction is along the vertical direction. In combination with Figure 7 As shown in the figure, the x-axis direction is the length direction, the y-axis direction is the thickness direction, and the z-axis direction is the height direction.

[0053] The air guide duct 140 needs to pressurize and deliver the cold air from the refrigeration air outlet 14 to the speed object placed in the refrigeration space 12. Therefore, the rapid cooling assembly 20 needs to have a relatively long length, and correspondingly, the size of the shell 100 of the rapid cooling assembly 20 in the length direction is the largest. At the same time, when the rapid cooling assembly 20 is assembled to the refrigeration space 12, it is necessary to reduce the influence of the setting of the rapid cooling assembly 20 on the accommodation capacity of the refrigeration space 12, and correspondingly, the size of the shell 100 of the rapid cooling assembly 20 in the thickness direction is smaller. When the circulating fan 200 is arranged, the size of the shell 100 of the rapid cooling assembly 20 needs to take into account the diameter of the fan blade of the circulating fan 200, and therefore, the size of the shell 100 in the height direction is greater than the size of the shell 100 in the thickness direction and smaller than the size of the shell 100 in the length direction.

[0054] With such a setting form, the rapid cooling assembly 20 has a small volume and occupies a small space, and the refrigeration equipment will not be significantly affected in accommodation capacity and visual aesthetics when the rapid cooling assembly 20 is arranged.

[0055] Optionally, the circulating fan 200 is a centrifugal fan, one end surface of the circulating fan 200 is at a predetermined distance from the inner wall of the shell 100 to form a low-pressure suction area 201, a partition 210 is arranged in the shell 100 to separate the low-pressure suction area 201 and the air guide duct 140, and the shell 100 is provided with an air inlet opening corresponding to the low-pressure suction area 201.

[0056] In the case where the circulating fan 200 is a centrifugal fan, the thickness of the rapid cooling assembly 20 can be made smaller. At the same time, the centrifugal fan also has the advantages of low cost, reliable function, and larger air volume under the same power.

[0057] When the circulation fan 200 is working, the area where one or two side end faces are located is the low-pressure suction area 201, and the position where the fan blade cooperates with the fan volute in the radial direction forms a high-pressure blowing outlet. The rotation axis of the fan blade of the circulation fan 200 is along the thickness direction of the shell 100, and there is a preset distance between the circulation fan 200 and the inner side wall of the shell 100 to form the low-pressure suction area 201, which is an integral part of the low-pressure suction area 201 of the circulation fan 200.

[0058] Since the circulation fan 200 is located in the air guide duct 140, the isolation member can isolate the fan mounting area 141 and other areas of the air guide duct 140, more specifically, isolate the low-pressure suction area 201 and other areas. The other areas are communicated with the high-pressure blowing outlet of the circulation fan 200. With such a setting form, the air inlet effect of the air inlet port can be formed without significantly increasing the thickness of the rapid cooling assembly 20.

[0059] Optionally, the isolation member 210 includes a foam material 211, which is lined between the circulation fan 200 and one end face of the shell 100, and the foam material 211 is compressed to isolate the low-pressure suction area 201 and the inclined connecting section 142.

[0060] The foam material 211 not only has a sealing and isolating effect, but also can absorb fan vibration. In the case of compressed assembly of the foam material, the foam material 211 can not only absorb the movement noise of the centrifugal fan to reduce the working noise of the rapid cooling assembly 20, but also can reduce or avoid the frosting of the shell 100 near the circulation fan 200 by setting the foam isolation form.

[0061] Optionally, one end face of the shell 100 along the length direction is provided with a first air inlet port 221 corresponding to the low-pressure suction area 201.

[0062] In the case of the air-cooled refrigerator as the refrigeration equipment, the rear end of the shell 100 along the length direction (the end of the rapid cooling assembly 20 away from the user when the user is located in front of the refrigerator) is provided with the first air inlet port 221. The first air inlet port 221 is closest to the refrigeration forming position, so the air inlet effect is more direct. In addition, the first air outlet is located away from the user, and the first air inlet port 221 is located in a position not easily observed by the user, so that the appearance of the rapid cooling assembly 20 and the refrigeration equipment can be improved.

[0063] Optionally, the lower side of the shell 100 is provided with a second air inlet port 222 corresponding to the low-pressure suction area 201.

[0064] The second air inlet port 222 is provided on the lower side of the shell 100, and in the use state, the second air inlet port 222 is located in a position not easily observed by the user, so that the appearance of the rapid cooling assembly 20 and the refrigeration equipment can be improved.

[0065] Optionally, a third air inlet 223 is formed on the outer side of the shell 100 corresponding to the low-pressure suction area 201.

[0066] The outer side of the shell 100 refers to one end surface of the shell 100 along the thickness direction. In the case where the rapid cooling assembly 20 is attached to the left side wall of the shell 100, the third air inlet 223 is located on the right side wall of the rapid cooling assembly 20. The right side wall of the rapid cooling assembly 20 has a large area, allowing the third air inlet 223 to have a large area. With such a configuration, the air inlet area of the rapid cooling assembly 20 can be further increased, thereby increasing the air outlet volume of the rapid cooling assembly 20.

[0067] Optionally, the outer side of the shell 100 is inwardly recessed to form an air inlet recess 131 corresponding to the area of the circulating fan 200, and a plurality of air inlet grooves 132 are formed in the air inlet recess 131 along a plurality of radial lines; the air inlet recess 131 forms an inclined guide surface from the outside to the inside.

[0068] With such a configuration, the plurality of air inlet grooves 132 can make the front shell 110 have a relatively complete structure, and prevent particulate matter in the refrigeration space 12 from entering the interior of the rapid cooling assembly 20. The air inlet recess 131 is bowl-shaped and forms a guide surface. When the refrigeration air outlet 14 discharges air, the cold air is close to the left and right inner side walls of the refrigeration space 12 under the effect of the attached wall. Through the inclined guide surface, the rapid cooling assembly 20 can better suck in the cold air close to the left and right side walls of the refrigeration space 12. With such a configuration, the air inlet volume of the rapid cooling assembly 20 is increased.

[0069] Optionally, the rapid cooling assembly 20 comprises an air inlet cover plate 130, the air inlet cover plate 130 covers the air inlet recess 131, and a gap 133 allowing air to enter is formed between the periphery of the air inlet cover plate 130 and the peripheral wall of the air inlet recess 131.

[0070] In the case where the air inlet cover plate 130 is provided, the air inlet cover plate 130 can shield the plurality of air inlet grooves 132 from the angle of observation of the user. This can improve the aesthetic appearance of the rapid cooling assembly 20. In addition, the gap 133 formed between the air inlet cover plate 130 and the peripheral wall of the air inlet recess 131 can better guide the cold air close to the left and right side walls of the refrigeration space 12 into the air guide duct 140 of the rapid cooling assembly 20, thereby improving the cooling speed of the rapid cooling assembly 20 for the rapid cooling object.

[0071] Optionally, the air guide duct 140 comprises, in sequence along the air flow direction, a fan mounting area 141, an inclined connecting section 142, and an air delivery section 143, 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 mounting area 141 is located at the air inlet end of the air guide duct 140, which can increase the air conveying distance of the air supply assembly. The circulating fan 200 is a centrifugal fan, and 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 position of the air supply section 143, so that the air blown out of the air outlet of the circulating fan 200 can be smoothly and naturally blown to the air supply section 143 through the inclined connecting section 142. With such an arrangement, the air volume loss of the air in the quick cooling assembly 20 can be reduced.

[0073] Optionally, the air supply section 143 comprises a conveying part 144 and a guide part 146, wherein the conveying part 144 is extended along the length direction of the housing 100 and has an air supply outlet opened downward; and the guide part 146 is extended along the length direction of the housing 100 corresponding to the air outlet, and the guide part 146 is inclined from inside to outside and from top to bottom to form a guide slope, so that the cold air blown out of the air supply outlet of the conveying part 144 is obliquely blown downward under the guide action of the guide part 146.

[0074] The conveying part 144 of the air supply section 143 has an air supply outlet opened downward, and the guide part 146 is extended along the length direction of the air supply outlet and forms a guide slope. When the air is blown out of the conveying part 144, the air is obliquely blown downward under the guide action of the guide slope. With such an arrangement, the position of the cold air blown out is relatively low. The cold air can better exchange heat with the quick cooling object under the action of the density difference between the cold air and the hot air, and the temperature of the cold air increases and moves upward during the heat exchange process. In this way, the cold air circulation in the area where the quick cooling assembly 20 is located can be optimized, and the heat exchange effect between the quick cooling object and the cold air can be improved.

[0075] In addition, the downward air supply outlet of the conveying part 144 and the inclined guide slope make the internal structure of the quick cooling assembly 20 not easy to be observed by the user, which can further improve the aesthetic appearance of the quick cooling assembly 20 and the refrigeration equipment.

[0076] Optionally, the quick cooling assembly 20 further comprises a lighting module 300, which is arranged on the inner top wall of the conveying part 144, and the lighting direction of the lighting module 300 is toward the guide part 146 to make the guide part 146 present a lighting effect.

[0077] The lighting module 300 is arranged on the inner top wall of the conveying portion 144, and the light emitted by the lighting module 300 is directed towards the air guide portion 146. The projection of the inclined air guide surface on the plane where the lighting module 300 is located coincides with the lighting module 300, so that the light emitted by the lighting module 300 can cover most of the area of the inclined air guide surface. For example, the light emitted by the lighting module 300 covers more than 95% of the area of the air guide surface. In addition, when the lighting module 300 emits light, the light is constrained by the two side walls of the conveying portion 144 in the thickness direction of the quick cooling assembly 20, and can only irradiate the inclined air guide surface below the air outlet of the conveying portion 144. When the lighting module 300 illuminates the air guide surface, the light emitted by the lighting module 300 will not irradiate other positions of the refrigeration space 12.

[0078] The lighting module 300 is arranged on the inner top wall of the conveying portion 144, and the light emitted by the lighting module 300 is directed towards the air guide portion 146. The projection of the inclined air guide surface on the plane where the lighting module 300 is located coincides with the lighting module 300, so that the light emitted by the lighting module 300 can cover most of the area of the inclined air guide surface. For example, the light emitted by the lighting module 300 covers more than 95% of the area of the air guide surface. In addition, when the lighting module 300 emits light, the light is constrained by the two side walls of the conveying portion 144 in the thickness direction of the quick cooling assembly 20, and can only irradiate the inclined air guide surface below the air outlet of the conveying portion 144. When the lighting module 300 illuminates the air guide surface, the light emitted by the lighting module 300 will not irradiate other positions of the refrigeration space 12.

[0079] Optionally, the inner top wall of the conveying portion 144 is concave upward to form a mounting space, and the lighting module 300 is embedded in the mounting space, and the downward side of the lighting module 300 is smoothly connected with the inclined connecting section 142.

[0080] In this case, after the lighting module 300 is installed, the transition between the inclined connecting section 142 and the air outlet section 143 is relatively smooth, which can reduce the air volume loss inside the quick cooling assembly 20.

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

[0082] The air outlet is a long and narrow air outlet, and the length of the air outlet in the length direction is greater than the length of the air outlet in the height direction. The ratio of the length of the air outlet to the length of the shell 100 is greater than or equal to 30%, so that the air outlet can cover most of the length of the quick cooling assembly 20. In the case where the quick cooling object is placed in the refrigeration space 12, the longer air outlet can increase the quick cooling range and improve the cooling speed of the quick cooling object.

[0083] The length of the air guide portion 146 is equal to the length of the air outlet, so that full coverage of the air guide inclined surface can be achieved. When the lighting module 300 emits light, the light emitting effect of the air guide inclined surface covers the entire length of the air outlet. With such a setting, the speed cooling assembly 20 and the light display effect can be further improved, and the display effect of the refrigeration equipment can be improved.

[0084] Optionally, the two opposite side walls of the air outlet section 143 are arranged in parallel, and the light emitted by the lighting module 300 is constrained by the two parallel side walls and is illuminated to the air guide inclined surface.

[0085] The thickness of the air outlet section 143 is equal from top to bottom, in which case, when the lighting module 300 emits light, the downwardly illuminated light is in the form of approximately parallel light, the light is illuminated to the air guide inclined surface, and then enters the human eye through diffuse reflection. In this way, the light leakage of the lighting module 300 can be reduced or avoided, and the light emission of the lighting module 300 is more concentrated, thereby improving the light display effect of the air guide inclined surface of the speed cooling assembly 20.

[0086] Optionally, the lighting module 300 comprises a light source plate 310, a light homogenizing plate 320 and a light shielding material 330, wherein the light source plate 310 is provided with a plurality of lamp beads; the light homogenizing plate 320 is arranged corresponding to the light source plate 310; and the light shielding material 330 covers the peripheral side of the light source plate 310 and the light homogenizing plate 320.

[0087] The light source plate 310 of the lighting module 300 is used for light emission, and the light source plate 310 is provided with a plurality of lamp beads, for example. The light homogenizing plate 320 is used for uniformly mixing the plurality of point light sources of the light source plate 310 into a surface light source. In this way, when the lighting module 300 emits light, no local bright spots are formed on the air guide inclined surface. The light shielding material 330 covers the peripheral side of the light source plate 310 and the light homogenizing plate 320, which can reduce or avoid light leakage of the lighting module 300. Especially near the housing 100 of the lighting module 300, the light is not easy to penetrate the side wall of the housing 100 to form a bright band. In addition, the light shielding material 330 covers the peripheral side of the light source plate 310 and the light homogenizing plate 320, which can also improve the overall waterproof capability of the lighting module 300.

[0088] Optionally, the light shielding material 330 is aluminum foil. In this way, the assembly of the lighting module 300 is facilitated, and the aluminum foil has good light shielding property and good waterproof property. With such a setting, the waterproof capability and the light leakage prevention capability of the lighting module 300 are further improved.

[0089] Optionally, the shell 100 comprises a rear shell 120 and a front shell 110, wherein the rear shell 120 is recessed to form an air outlet groove 121 on one side and a wiring space 122 on the other side; the front shell 110 is combined with the rear shell 120, the front shell 110 is combined to the air outlet groove 121 to form an air guide duct 140, and the front shell 110 is provided with an air outlet; wherein the air guide part 146 is an integral structure with the rear shell 120, or the air guide part 146 is an integral structure with the front shell 110.

[0090] The rear shell 120 is connected to the inner wall of the refrigeration equipment. One side of the rear shell 120 facing the refrigeration space 12 is recessed to form an air outlet groove 121 away from the refrigeration space 12, and the other side of the rear shell 120 facing away from the refrigeration space 12 is recessed to form a wiring space 122. In this way, the structural strength of the rear shell 120 can be improved, thereby improving the overall structural strength of the shell 100. The front shell 110 is combined to the air outlet groove 121 of the rear shell 120, and the air outlet groove 121 forms an air guide duct 140. One side of the front shell 110 facing the refrigeration space 12 is provided with an air outlet. The air guide part 146 is an integral structure with the front shell 110 or the rear shell 120, which can simplify the number of components of the shell 100, thereby reducing the assembly difficulty of the rapid cooling assembly 20.

[0091] With such a setting form, the circulating fan 200, the lighting module 300 and the corresponding connection wire harness can be conveniently arranged in the rear shell 120, and the wiring space 122 and the air guide duct 140 are isolated.

[0092] Optionally, the air guide duct 140 comprises a fan mounting area 141, an inclined connecting section 142 and an air sending section 143 arranged in sequence along the air flow direction, and the outlet of the circulating fan 200 is higher or lower than the position of the air sending section 143; the rapid cooling assembly 20 further comprises a circulating fan 200, the circulating fan 200 is arranged in the fan mounting area 141, and the outlet of the circulating fan 200 is connected with the air sending section 143 through the inclined connecting section 142.

[0093] Optionally, the shell 100 is provided with a temperature detection hole 124 on the same side as the air outlet, and a temperature detection area 125 isolated from the air guide duct 140 is formed inside the shell 100 corresponding to the temperature detection hole 124; the rapid cooling assembly 20 further comprises an infrared temperature sensor 400, the infrared temperature sensor 400 is arranged in the temperature detection area 125, and the infrared temperature sensor 400 detects the temperature of the rapid cooling object and / or the background temperature through the temperature detection hole 124.

[0094] The temperature detection hole 124, the third air inlet 223, and the air outlet are all arranged on the outward side of the shell 100. The temperature detection area 125 is formed inside the shell 100. Since the temperature detection area 125 is isolated from the air guide duct 140, the detection of the infrared temperature sensor 400 on the temperature can be reduced or avoided. The infrared temperature sensor 400 detects the temperature of the rapid cooling object, which can be used to determine whether to cool the rapid cooling object and determine the rotation speed of the fan according to the temperature of the rapid cooling object. The infrared temperature sensor 400 detects the background temperature, which can determine whether the temperature of the area corresponding to the infrared temperature sensor 400 is too high or too low, so as to control the start and stop of the rapid cooling assembly 20.

[0095] With such an arrangement, the infrared temperature sensor 400 can identify the temperature of the rapid cooling object, providing a basis for the start and stop and rotation speed of the circulating fan.

[0096] Optionally, the rapid cooling assembly 20 further comprises a battery 510 arranged in the shell 100.

[0097] In the case where the rapid cooling assembly 20 further comprises a battery 510, the rapid cooling assembly 20 can drive the circulating fan 200 to rotate without the power supply of the refrigerator. This not only makes the installation position of the rapid cooling assembly 20 not limited by the wiring harness connection, but also makes the rapid cooling assembly 20 adapt to different forms of refrigerators. The rapid cooling assembly 20 has a built-in battery 510, which can also be equipped with a rapid cooling function after being assembled to a refrigerator without a rapid cooling function.

[0098] Optionally, the rapid cooling assembly 20 further comprises a manual switch connected to the circulating fan 200.

[0099] When the user needs to use the rapid cooling function, the user opens the manual switch of the rapid cooling assembly 20. After the rapid cooling is completed, the user manually closes the rapid cooling assembly 20. In this way, the rapid cooling function of the rapid cooling assembly 20 is not dependent on the temperature sensor and the processor, which simplifies the structure of the rapid cooling assembly 20 and reduces the cost of the rapid cooling assembly 20.

[0100] Optionally, the rapid cooling assembly 20 further comprises a battery 510 and a timing switch 520 connected to the circulating fan 200.

[0101] As one use scenario, after the user puts in the refrigeration object, the user needs the rapid cooling assembly 20 to rapidly cool the refrigeration object for about half an hour. The user turns or sets the timing switch 520 to half an hour, and the circulating fan 200 can automatically stop after half an hour. With such a setting form, the user's use is further facilitated.

[0103] The refrigerator includes a cabinet 10 and a cabinet door, the cabinet 10 defines a refrigeration space 12, and the cabinet door is used to open or close the refrigeration space 12. A rear wall of the refrigeration space 12 is provided with a refrigeration air outlet 14. The above-mentioned rapid cooling assembly 20 is mounted to a left side wall or a right side wall of the refrigeration space 12, the rapid cooling assembly 20 is mounted transversely, an air inlet is located at one end close to the rear wall of the refrigeration space 12, and an air outlet faces a rapid cooling object in the refrigeration space 12.

[0104] The refrigerator disclosed in the present application can realize normal refrigeration cooling of the refrigeration space 12 when the fan of the rapid cooling assembly 20 is not started. After a rapid cooling object is placed in the refrigeration space 12, the circulating fan 200 of the rapid cooling assembly 20 is started to quickly reduce the temperature of the rapid cooling object. When the temperature of the rapid cooling object is reduced, the flow rate and flow of the cold air blown to the rapid cooling object can be increased, and the temperature of the cold air blown to the rapid cooling object can be reduced by using the refrigerator disclosed in the present application, so that the heat convection heat exchange effect on the rapid cooling object is improved, and the cooling rate of the rapid cooling object is improved. In addition, the air guide duct 140 of the rapid cooling assembly 20 is open-joint with the refrigeration chamber, which can reduce the cost increase caused by the setting of an additional air duct, and reduce the normal refrigeration effect of the refrigeration equipment refrigeration space 12 of the rapid cooling assembly 20 when the circulating fan 200 is not started.

[0105] The inner wall of the refrigeration space 12 includes a left side wall, a right side wall, a top side wall, a bottom wall and a rear wall. In the case that a partition plate or the like is arranged in the refrigeration space 12, the top side wall of the refrigeration space 12 further includes a downward side of the partition plate, or the bottom side wall of the refrigeration space 12 further includes an upward side of the partition plate.

[0106] Optionally, one rapid cooling assembly 20 is arranged on each of the left side wall and the right side wall of the refrigeration space 12.

[0107] By adopting such a setting form, the cooling speed of the rapid cooling object can be further improved.

[0108] Optionally, the rapid cooling assembly 20 is detachably mounted to the inner wall of the refrigeration space 12.

[0109] The refrigerator provided by the embodiment of the present disclosure is provided with the rapid cooling assembly 20, which can rapidly reduce the temperature of the rapid cooling object in a region of the refrigeration space 12; the rapid cooling assembly 20 is in a detachable form, and the rapid cooling assembly 20 can be assembled to different layers or different regions of the refrigeration space 12 according to actual needs, thereby improving the rapid cooling efficiency and facilitating the use of the user.

[0110] Optionally, the rapid cooling assembly 20 further comprises a suction cup 530, and the rapid cooling assembly 20 is adsorbed to the inner wall of the refrigeration space 12 through the suction cup 530.

[0111] The rapid cooling assembly 20 is provided with the suction cup 530, and the suction cup 530 can be adsorbed to the smooth inner wall of the refrigeration space 12. When the rapid cooling object needs to be rapidly cooled, the rapid cooling assembly 20 is adsorbed to the specified region. When the position is changed, the suction cup 530 can conveniently take down the rapid cooling assembly 20 after pressure relief. By adopting such a setting mode, the rapid cooling assembly 20 is easy to disassemble and has low cost.

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

[0113] As an optional embodiment, the shell 100 of the rapid cooling assembly 20 is constructed with an adsorption groove, and the suction cup 530 is arranged in the adsorption groove. In this way, after the rapid cooling assembly 20 is assembled to the refrigeration space 12, the rapid cooling assembly 20 as a whole will not protrude too much from the inner wall of the box body 10, which can improve the appearance of the refrigerator and reduce the impact on the accommodation capacity of the refrigeration space 12 caused by the setting of the rapid cooling assembly 20.

[0114] Optionally, the sidewall of the box body 10 is provided with a first magnetic attraction piece 15, and the rapid cooling assembly 20 comprises a second magnetic attraction piece 540, and the first magnetic attraction piece 15 cooperates with the second magnetic attraction piece 540 to fix the rapid cooling assembly 20 to the inner wall of the refrigeration space 12.

[0115] As an optional embodiment, the inner liner 11 of the refrigeration space 12 is a metal inner liner 11, and the metal inner liner 11 serves as the first magnetic attraction piece 15. The rapid cooling assembly 20 is provided with a magnet, and the magnet serves as the second magnetic attraction piece 540. As another optional embodiment, a metal sheet is pre-embedded in the foamed layer of the inner liner 11, and the metal sheet serves as the first magnetic attraction piece 15. The rapid cooling assembly 20 is provided with a magnet, and the magnet serves as the second magnetic attraction piece 540. The rapid cooling assembly 20 is disassembled in the form of cooperation between the first magnetic attraction piece 15 and the second magnetic attraction piece 540, which not only further facilitates the use of the user but also can optimize the feel of disassembling the rapid cooling assembly 20.

[0116] Optionally, the sidewall of the box body 10 is provided with a first cooperation piece 16, and the rapid cooling assembly 20 comprises a second cooperation piece 550, and the first cooperation piece 16 cooperates with the second cooperation piece 550 to fix the rapid cooling assembly 20 to the inner wall of the refrigeration space 12.

[0117] As an optional implementation, the first fitting member 16 is a screw hole, the second fitting member 550 is a screw, and the quick cooling assembly 20 is fixed to the inner wall of the refrigeration space 12 by means of screwing. With such an arrangement, the fixing effect of the quick cooling assembly 20 is good, and the implementation cost of the detachable structure of the quick cooling assembly 20 and the refrigerator is low.

[0118] As another optional implementation, the side wall of the box body 10 is provided with a clamping part, and the quick cooling assembly 20 is provided with a clamping fitting part. The quick cooling assembly 20 is fixed to the inner wall of the refrigeration space 12 by clamping. With such an arrangement, the quick cooling assembly 20 can be accurately positioned to the installation position, which is conducive to the realization of the quick cooling function of the quick cooling assembly 20.

[0119] Optionally, the box body 10 includes an inner container 11 and an air duct assembly 13, wherein the inner container 11 defines the refrigeration space 12; the air duct assembly 13 is arranged on the rear wall of the refrigeration space 12 and is at a predetermined distance from the left and right side walls of the refrigeration space 12. The air duct assembly 13 forms a refrigeration air duct inside, and the outlet of the refrigeration air duct faces the left and right side walls.

[0120] The inner container 11 of the box body 10 defines the 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 container 11 and is at a predetermined distance from the left and right side walls of the inner container 11. When the air duct assembly 13 blows out, it blows cold air towards the left and right side walls of the inner container 11. With such an arrangement, when the refrigerator is opened, the refrigeration air outlet will not blow directly on the user, reducing the loss of coldness and improving the user's experience. In the case where the air duct assembly 13 blows out towards the left and right side walls of the inner container 11, the quick cooling assembly 20 is arranged to pressurize and deliver cold air to the quick cooling object. This makes the quick cooling function and the ordinary refrigeration function of the refrigerator can be clearly distinguished.

[0121] Optionally, the distance between the air inlet of the quick cooling assembly 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 refrigeration space 12 is in front of the front side of the air duct assembly 13. In the case that the air inlet of the quick cooling assembly 20 is open to the refrigeration air outlet 14, if the distance between the air inlet and the refrigeration air outlet 14 is too small, the cold air sucked by the quick cooling assembly 20 is more difficult, and the air volume of the quick cooling assembly 20 will be affected. If the distance between the air inlet and the air outlet is too large, the air entering the air inlet of the quick cooling assembly 20 is mostly the air in the refrigeration space 12, and the temperature of the air outlet of the quick cooling assembly 20 is higher, which will affect the cooling speed of the refrigeration object. The distance between the air inlet of the quick cooling assembly 20 and the rear wall of the refrigeration space 12 is between 10mm and 50mm, the cold air sucked by the quick cooling assembly 20 is more, and the cold air sucked by the quick cooling assembly 20 is output at the position of the refrigeration air outlet 14. With such a setting form, the cooling speed of the quick cooling assembly 20 for the quick cooling object can be further improved.

[0123] Optionally, a wireless charging coil is arranged in the foaming layer of the refrigerator, and the quick cooling assembly 20 is provided with a wireless charging module.

[0124] In this case, the user can place the quick cooling assembly 20 at the position of the wireless charging coil to charge the quick cooling assembly 20, and the charging of the quick cooling assembly 20 is also completed in the refrigeration space 12. In this way, the convenience of using the quick cooling assembly 20 can be further improved.

[0125] Optionally, the refrigerator forms a quick cooling area 17 in the refrigeration space 12, and the quick cooling assembly 20 is arranged in the quick cooling area 17.

[0126] With such a setting form, the refrigerator can realize partitioned refrigeration of different areas of the refrigeration space.

[0127] Optionally, the refrigerator provided by the embodiment of the present disclosure comprises a cabinet, a temperature sensor and a quick cooling fan. The cabinet is internally structured with a refrigeration chamber, and the refrigeration chamber is internally provided with a quick cooling space. The temperature sensor is arranged inside the quick cooling space and is used to detect the temperature in the quick cooling space. The quick cooling fan is arranged inside the quick cooling space and is used to guide the cold air to be branched to the inside of the quick cooling space.

[0128] In the subsequent description, the "quick cooling space" and the "quick cooling area" are the same terms, the "refrigeration chamber" and the "refrigeration space" are the same terms, and the "heat source" and the "quick cooling object" are the same terms.

[0129] Optionally, the refrigerator further comprises a control device 600 mounted inside the cabinet and electrically connected with the temperature sensor and the quick cooling fan. In this way, the embodiment of the present disclosure can execute the corresponding control method through the control device 600 to quickly cool the heat source when the user puts it in.

[0130] Based on the above refrigerator, in combination 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] In this way, the embodiments of the present disclosure can continuously detect the temperature in the rapid cooling space by using NTC thermistors, which can provide highly localized and refined temperature data when arranged in a distributed array. This enables the system to not only determine whether a heat source is placed in the rapid cooling space, but also accurately determine the actual position, specific quantity and approximate size of the heat source by analyzing the temperature data of different NTC points, thereby providing a solid data foundation for subsequent directional air supply or differentiated air supply strategies, and significantly improving the accuracy and efficiency of cold distribution.

[0138] Optionally, the control device controls the operating state of the rapid cooling fan according to the temperature in the rapid cooling space, including: in the case that the temperature in the rapid cooling space meets the heat source placement condition, the control device controls the rapid cooling fan to start running to guide the cooling air to cool the heat source in the rapid cooling space; in the case that the temperature in the rapid cooling space meets the heat source temperature condition, the control device controls the rapid cooling fan to stop running to stop guiding the cooling air to cool the heat source in the rapid cooling space.

[0139] In this way, the embodiments of the present disclosure can start the rapid cooling fan when the temperature in the rapid cooling space meets the heat source placement condition, and stop the rapid cooling fan when the temperature in the rapid cooling space meets the heat source temperature condition, thereby constructing a complete rapid cooling function closed-loop control logic and realizing on-demand operation of the rapid cooling fan, avoiding unnecessary long-time operation and effectively reducing energy consumption.

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

[0141] In this way, the embodiments of the present disclosure arrange the rapid cooling fan inside the rapid cooling space and make it use the main air duct of the refrigeration compartment to deliver cooling air, which effectively utilizes the existing main air duct and cold circulation of the refrigerator and avoids the complexity brought by additional establishment of an independent air duct system. By embedding the rapid cooling fan in the target rapid cooling space, the embodiments of the present disclosure realize the nearby and efficient use of existing cold resources, thereby simplifying the air duct design of the whole machine and effectively reducing the manufacturing cost.

[0142] Further, as shown in Figures 1-8 The rapid cooling fan can be installed inside the rapid cooling assembly, and at this time, the circulating fan 200 of the rapid cooling assembly corresponds to the rapid cooling fan.

[0143] In this way, the embodiment of the present disclosure can improve the flow rate, flow volume and temperature of the cold air blown to the heat source when reducing the temperature of the heat source by the rapid cooling assembly, thereby improving the heat convection exchange effect on the heat source and improving the cooling rate of the heat source. In addition, the air guide duct of the rapid cooling assembly is in open docking with the refrigeration chamber, which can reduce the cost increase caused by the additional air duct and reduce the normal refrigeration effect of the rapid cooling assembly on the refrigeration chamber when the circulating fan is not turned on.

[0144] Optionally, in other embodiments, the rapid cooling space is in communication with the freezing chamber through an auxiliary air duct, and the rapid cooling fan is arranged at the outlet of the auxiliary air duct corresponding to the inside of the rapid cooling space, so that more cold air in the freezing chamber is diverted to the inside of the rapid cooling space.

[0145] Optionally, in other embodiments, the rapid cooling space is in communication with the freezing chamber through an auxiliary air duct, and the rapid cooling fan is arranged at the inlet of the auxiliary air duct corresponding to the inside of the freezing chamber, so that more cold air in the freezing chamber is diverted to the inside of the rapid cooling space.

[0146] In this way, the embodiment of the present disclosure arranges the rapid cooling fan at the outlet or inlet of the auxiliary air duct in communication with the freezing chamber, so that the low-temperature cold air in the freezing chamber is transported to the inside of the rapid cooling space, which provides a lower-temperature and stronger cold source for the rapid cooling space. By utilizing the low-temperature cold air in the freezing chamber, the system can perform more powerful and rapid cooling on the high-temperature heat source, thereby significantly improving the efficiency and performance of the rapid cooling function. This ensures that the heat source can be effectively cooled in the shortest time regardless of the temperature of the heat source, meeting the extreme rapid cooling demand of the user.

[0147] Optionally, the heat source placement condition includes that the temperature in the rapid cooling space is greater than or equal to a preset start-up temperature, and the temperature change rate in the rapid cooling space is greater than or equal to a preset temperature change rate.

[0148] In this way, the embodiment of the present disclosure can utilize the temperature and temperature change rate in the rapid cooling space to determine the heat source placement condition, overcome the misjudgment defect caused by single-dimensional judgment, accurately identify the real heat source placement event, effectively exclude the false triggering caused by taking out the heat source before closing the door, improve the accuracy and reliability of the rapid cooling function, and avoid energy waste caused by misjudgment.

[0149] Optionally, the preset start-up temperature can be set in combination with the refrigeration temperature in the box. For example, the preset start-up temperature can be set to 10℃ to exclude the false triggering caused by taking out the heat source before closing the door, thereby identifying the real heat source placement event. The preset start-up temperature can also be adjusted according to the actual demand of the user, and can also be set to other arbitrary reasonable values.

[0150] Optionally, the preset temperature change rate can be set in combination with the difference between the temperature outside the box and the refrigeration temperature inside the box. For example, the preset temperature change rate can be set to 2℃ / s to exclude false triggering caused by mistaken judgment due to taking out things by hand, so as to identify the real heat source placement event. The preset temperature change rate can also be adjusted according to actual user needs, and can also be set to any other reasonable value.

[0151] Optionally, the temperature in the rapid cooling space includes the heat source temperature and the ambient temperature; the heat source temperature reaching condition includes: the heat source temperature in the rapid cooling space is less than or equal to the preset shutdown temperature; and / or, the difference between the heat source temperature in the rapid cooling space and the ambient temperature is less than or equal to the preset shutdown temperature difference; and / or, the continuous running time of the rapid cooling fan is greater than or equal to the preset running time.

[0152] In this way, the embodiments of the present disclosure can use a variety of heat source temperature reaching conditions for combined judgment, including whether the heat source temperature 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., so as to provide multiple and flexible judgment basis for accurate shutdown of the rapid cooling function, which not only ensures that the heat source is fully cooled, but also stops running in time to avoid excessive refrigeration and ensure energy efficiency.

[0153] Optionally, the preset shutdown temperature can be set in combination with the refrigeration temperature inside the box. For example, the preset shutdown temperature can be set to 6℃ to ensure that the heat source is fully cooled, so as to realize accurate shutdown of the rapid cooling function. The preset shutdown temperature can also be adjusted according to actual user needs, and can also be set to any other reasonable value.

[0154] Optionally, the preset shutdown temperature difference can be set in combination with the refrigeration temperature inside the box. For example, the preset shutdown temperature difference can be set to 2℃ to ensure that the heat source is fully cooled, so as to realize accurate shutdown of the rapid cooling function. The preset shutdown temperature difference can also be adjusted according to actual user needs, and can also be set to any other reasonable value.

[0155] Optionally, the preset running time can be set in combination with the refrigeration temperature inside the box. For example, the preset running time can be set to 12h to ensure that the heat source is fully cooled, so as to realize accurate shutdown of the rapid cooling function. The preset running time can also be adjusted according to actual user needs, and can also be set to any other reasonable value.

[0156] Optionally, the temperature in the rapid cooling space includes the heat source temperature and the ambient temperature; after the control device controls the rapid cooling fan to start running, the control device further adjusts the working speed of the rapid cooling fan according to the heat source temperature in the rapid cooling space. The working speed of the rapid cooling fan is positively correlated with the heat source temperature in the rapid cooling space.

[0157] In this way, the working speed of the rapid cooling fan is positively correlated with the heat source temperature in the rapid cooling space, so as to dynamically adjust the refrigeration intensity according to the heat source load. That is, the higher the heat source temperature, the greater the working speed of the rapid cooling fan set accordingly, and the stronger the cold energy delivery corresponding to the rapid cooling space, 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 working speed of the rapid cooling fan according to the heat source temperature in the rapid cooling space, including: in the case that 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 instruction to enable the rapid cooling fan to operate at a high speed; or in the case that 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 instruction to enable the rapid cooling fan to operate at a medium speed; or in the case that 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 instruction to enable the rapid cooling fan to operate at a low speed.

[0159] In this way, the working speed of the rapid cooling fan is positively correlated with the heat source temperature in the rapid cooling space, so as to dynamically adjust the refrigeration intensity according to the heat source load. That is, the higher the heat source temperature, the greater the working speed of the rapid cooling fan set accordingly, and the stronger the cold energy delivery corresponding to the rapid cooling space, thereby improving the rapid cooling efficiency, shortening the cooling time, and optimizing the on-demand distribution of energy.

[0160] Optionally, after the control device controls the rapid cooling fan to start operating, the control device further includes: the control device acquires a working gear of the refrigeration compartment; and the control device adjusts the working speed of the rapid cooling fan according to the working gear of the refrigeration compartment. The working speed of the rapid cooling fan is negatively correlated with a target refrigeration temperature corresponding to the working gear.

[0161] In this way, the working speed of the rapid cooling fan is positively correlated with the heat source temperature in the rapid cooling space, so as to dynamically adjust the refrigeration intensity according to the heat source load. That is, the higher the heat source temperature, the greater the working speed of the rapid cooling fan set accordingly, and the stronger the cold energy delivery corresponding to the rapid cooling space, thereby improving the rapid cooling efficiency, shortening the cooling time, and optimizing the on-demand distribution of energy.

[0162] Optionally, the control device adjusts the working speed of the quick cooling fan according to the working mode of the refrigeration compartment, including: in a case where the target refrigeration temperature corresponding to the working mode of the refrigeration compartment is less than a first refrigeration temperature threshold, the control device outputs a first speed instruction to enable the quick cooling fan to operate at a high speed; or in a case where the target refrigeration temperature corresponding to the working mode of the refrigeration compartment is greater than or equal to the first refrigeration temperature threshold and less than a second refrigeration temperature threshold, the control device outputs a second speed instruction to enable the quick cooling fan to operate at a medium speed; or in a case where the target refrigeration temperature corresponding to the working mode of the refrigeration compartment is greater than or equal to the second refrigeration temperature threshold, the control device outputs a third speed instruction to enable the quick cooling fan to operate at a low speed.

[0163] In this way, the embodiment of the disclosure can dynamically adjust the working speed of the quick cooling fan according to the working mode of the refrigeration compartment, so as to deeply integrate the local quick cooling function with the overall operation strategy of the refrigerator. By linking the speed of the quick cooling fan with the refrigeration temperature mode set by the user, the system can ensure that the quick cooling operation is always consistent with the overall refrigeration target of the refrigerator, for example, the quick cooling intensity is reduced accordingly in the energy-saving mode. This not only maintains the overall stability of the temperature inside the refrigerator, but also avoids additional energy consumption caused by function conflicts.

[0164] Optionally, the control method further includes: in a case where the temperature in the quick cooling space meets the heat source placement condition, the control device controls the atmosphere lamp to start operating to prompt the user that the cold air is cooling the heat source in the quick cooling space.

[0165] In this way, the embodiment of the disclosure can provide the user with an intuitive function state prompt through the start of the atmosphere lamp, thereby enhancing the friendliness of human-computer interaction and enabling the user to clearly perceive the start of the quick cooling function, thereby improving the user experience.

[0166] Optionally, after the control device controls the atmosphere lamp to start operating, the method further includes: in a case where the refrigerator door is opened, the control device adjusts the working brightness of the atmosphere lamp according to the working speed of the quick cooling fan. The working brightness of the atmosphere lamp is positively correlated with the working speed of the quick cooling fan.

[0167] In this way, when the refrigerator door is opened, the embodiment of the disclosure can provide the user with an intuitive and dynamic visual feedback by adjusting the working brightness of the atmosphere lamp. When the quick cooling fan operates at a high speed, the brightness of the atmosphere lamp is increased accordingly, thereby intuitively showing the user that the system is performing a powerful cooling. This makes the invisible quick cooling process visualized, thereby improving the user experience and the friendliness of human-computer interaction.

[0168] Optionally, after the control device controls the atmosphere lamp to start operating, the method further includes: in a case where the refrigerator door is closed, the control device controls the atmosphere lamp to be turned off.

[0169] In this way, when the refrigerator door is closed, the user cannot see the atmosphere lamp, and the light is turned off at this time, which can save energy and meet the user's use logic. Therefore, the atmosphere lamp can be directly turned off in the embodiment of the disclosure to achieve on-demand control of the atmosphere lamp.

[0170] Optionally, in combination with Figure 4 and 7 As shown, the atmosphere lamp can be installed inside the rapid cooling assembly, at this time, the lighting module 300 of the rapid cooling assembly corresponds to the atmosphere lamp.

[0171] In this way, the embodiment of the disclosure can adopt the form of arranging the lighting module above and the air guide inclined surface below in the air delivery section of the air guide duct of the rapid cooling assembly, which not only makes the air guide inclined surface present a light emitting effect, but also makes the light emitted by the lighting module only illuminate the air guide inclined surface under the constraint of the air delivery section, thereby further reducing or avoiding the situation that the lighting module leaks light to other positions, and improving the display effect of the rapid cooling assembly and the refrigerator.

[0172] Based on the above refrigerator, in combination with Figure 10 As shown, the embodiment of the disclosure provides another control method for a refrigerator, comprising:

[0173] S201, in the case of detecting the refrigerator door opening and closing action, the control device controls the temperature sensor to continuously detect the temperature in the rapid cooling space.

[0174] S202, in the case that the temperature in the rapid cooling space meets the heat source placement condition, the control device controls the rapid cooling fan to start running to guide the cold air to cool the heat source in the rapid cooling space.

[0175] S203, in the case that the temperature in the rapid cooling space meets the heat source frost condition, the control device controls the rapid cooling fan to run intermittently to avoid the heat source frost.

[0176] The control method for a refrigerator provided by the embodiment of the disclosure controls the rapid cooling fan to run intermittently to avoid the heat source frost in the case that the temperature in the rapid cooling space meets the heat source frost condition. Therefore, the embodiment of the disclosure can guarantee the rapid cooling effect while effectively avoiding the frosting risk caused by excessive refrigeration. Through the short fan stop, the embodiment of the disclosure can allow the local temperature around the heat source surface to moderately rise, thereby effectively preventing water vapor from condensing into frost or water droplets, avoiding the damage to food quality, and maintaining the sanitary environment inside the refrigerator. This intelligent and dynamic anti-frost control realizes the "soft landing" in the rapid cooling process, and balances the refrigeration efficiency and food safety.

[0177] Optionally, the heat source placement condition comprises: the temperature in the rapid cooling space is greater than or equal to a preset start temperature; and the temperature change rate in the rapid cooling space is greater than or equal to a preset temperature change rate.

[0178] In this way, the embodiment of the present disclosure can use the temperature and the temperature change rate in the rapid cooling space to determine the heat source placement condition, overcome the misjudgment defects caused by single dimension judgment, accurately identify the real heat source placement event, effectively eliminate the false triggering caused by the misjudgment of the hand taking things or the heat source being taken out before the door is closed, improve the accuracy and reliability of the rapid cooling function, and thus avoid the energy waste caused by misjudgment.

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

[0180] In this way, the embodiment of the present disclosure includes the ambient temperature and / or the heat source temperature in the rapid cooling space in the frost determination, so that the frost risk point can be more accurately grasped to ensure that the rapid cooling fan only starts intermittent operation when there is a frost risk, and fine frost control is achieved.

[0181] Optionally, the first frost temperature can be set in combination with the refrigeration temperature in the box. For example, the first frost temperature can be set to 0℃ to more accurately grasp the frost risk point, so that fine frost control is achieved. The first frost temperature can also be adjusted according to actual user needs, and can also be set to any other reasonable value.

[0182] Optionally, the second frost temperature can be set in combination with the refrigeration temperature in the box. For example, the second frost temperature can be set to 2℃ to more accurately grasp the frost risk point, so that fine frost control is achieved. The second frost temperature can also be adjusted according to actual user needs, and can also be set to any other reasonable value.

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

[0184] In this way, the embodiment of the present disclosure can control the rapid cooling fan to alternate between starting operation for a first duration and stopping operation for a second duration, so as to achieve intermittent operation, so that the local temperature can rise again by temporarily stopping air supply while continuously cooling the heat source, thereby effectively avoiding frost formation.

[0185] Optionally, the first time length can be set in combination with the refrigeration temperature in the box. Exemplarily, the first time length can be set to 1 min to ensure a rapid cooling effect, thereby improving the food storage effect. The first time length can also be adjusted according to actual user needs, and can also be set to other arbitrary reasonable values.

[0186] Optionally, the second time length can be set in combination with the refrigeration temperature in the box. Exemplarily, the second time length can be set to 1 min to allow the local temperature to rise, thereby effectively avoiding frost formation. The second time length can also be adjusted according to actual user needs, and can also be set to other arbitrary reasonable values.

[0187] Optionally, the control device cyclically executes the following steps until the temperature in the rapid cooling space does not meet the frost condition of the heat source, and further comprises: the control device determines heat source information in the rapid cooling space; and the control device determines the first time length and the second time length according to the heat source information in the rapid cooling space.

[0188] In this way, before performing the intermittent operation, the embodiment of the present disclosure first determines the heat source information in the rapid cooling space, and determines the first time length and the second time length according to the information. The embodiment of the present disclosure can change the control of the intermittent operation from a fixed time 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, for example, prolonging the operation time for high-temperature heat sources or low-humidity heat sources, thereby effectively performing rapid cooling while accurately controlling the rhythm of frost prevention, and improving the overall efficiency and accuracy of the scheme.

[0189] Optionally, the heat source information in the rapid cooling space includes a heat source temperature; and the control device determines the first time length and the second time length according to the heat source information in the rapid cooling space, including: in a case where the heat source temperature in the rapid cooling space is greater than or equal to a preset heat source temperature, the control device determines the first time length to be T 11 and the second time length to be T 21 ; or in a case where the heat source temperature in the rapid cooling space is less than the preset heat source temperature, the control device determines the first time length to be T 12 and the second time length to be T 22 . Wherein, T 11 +T 21 =T 12 +T 22 , T 11 / T 21 >T 12 / T 22 .

[0190] In this way, when the heat source temperature is high, the embodiment of the present disclosure will allocate a larger operation / stop time length ratio (T 11 / T 21), to ensure that frost protection can be provided while providing more consistent and stronger cold output, thereby improving the efficiency of the rapid cooling. This ensures that the control strategy can match the actual cooling needs of the heat source, achieving a balance between efficiency and effectiveness.

[0191] Optionally, the heat source information in the rapid cooling space includes heat source humidity; the control device determines the first time length and the second time length according to the heat source information in the rapid cooling space, including: in the case that the heat source humidity in the rapid cooling space is greater than or equal to the preset heat source humidity, the control device determines the first time length as T 13 , and determines the second time length as T 23 ; or, in the case that the heat source humidity in the rapid cooling space is less than the preset heat source humidity, the control device determines the first time length as T 14 , and determines the second time length as T 24 . Wherein, T 13 +T 23 =T 14 +T 24 , T 13 / T 23 <T 14 / T 24 .

[0192] In this way, when the heat source humidity is high, the heat source with high water content is more likely to produce water vapor and frost. The present embodiment allocates a smaller running / stop time length ratio (T 13 / T 23 ) to it, which means that the fan will stop more frequently, thereby effectively preventing water vapor from condensing into frost at the source. This ensures that the frost protection strategy can directly act on the root cause of frost, providing efficient and energy-saving frost protection.

[0193] Optionally, the control method further includes: in the case that the temperature in the rapid cooling space meets the heat source frost condition, the control device acquires a continuous frost time length; in the case that the continuous frost time length is greater than or equal to a preset frost time length, the control device controls the rapid cooling fan to stop running to stop guiding the cold air to cool the heat source in the rapid cooling space.

[0194] In this way, the present embodiment can further determine the continuous frost time length when there is a frost risk, thereby forming a double insurance mechanism. If the rapid cooling fan cannot solve the frost problem after intermittent operation for a period of time, the system will forcibly stop the rapid cooling fan to maximize food safety and prevent the risk of freezing damage in extreme cases.

[0195] Optionally, the preset frost duration can be set in combination with the refrigeration temperature in the box. For example, the preset frost duration can be set to 10 minutes to determine that the intermittent operation cannot 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 actual needs of the user, and can also be set to any other reasonable value.

[0196] Optionally, the control method further includes: in a case where the temperature in the rapid cooling space meets the heat source temperature reaching condition, the control device controls the rapid cooling fan to stop running to stop guiding the cold air to cool the heat source in the rapid cooling space.

[0197] In this way, the embodiments of the present disclosure can ensure that the function is exited in time after the rapid cooling is completed by combining the heat source temperature reaching condition, thereby avoiding waste of cold energy and preventing long-term high-load operation of the fan.

[0198] Optionally, the temperature in the rapid cooling space includes the heat source temperature and the ambient temperature; the heat source temperature reaching condition includes: the heat source temperature in the rapid cooling space is less than or equal to a preset shutdown temperature; and / or, the difference between the heat source temperature and the ambient temperature in the rapid cooling space is less than or equal to a preset temperature difference; and / or, the continuous running time of the rapid cooling fan is greater than or equal to a preset running time.

[0199] In this way, the embodiments of the present disclosure can use a variety of heat source temperature reaching conditions for combined determination, including whether the heat source temperature 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, thereby providing multiple and flexible determination bases for accurate shutdown of the rapid cooling function, which not only ensures that the heat source is fully cooled, but also stops running in time to avoid excessive refrigeration and ensure energy efficiency.

[0200] Based on the above refrigerator, in combination with Figure 11 The embodiments of the present disclosure provide another control method for a refrigerator, which includes:

[0201] S301, in a case where it is detected that the refrigerator door is opened, the control device controls the temperature sensor to continuously detect the temperature in the rapid cooling space.

[0202] S302, in a case where the temperature in the rapid cooling space meets the heat source putting-in condition, 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 running to guide the cold air to cool the heat source in the rapid cooling space according to the heat source information in the rapid cooling space.

[0204] The control method for the refrigerator provided by the embodiment of the present disclosure can further determine the specific heat source information when the temperature in the rapid cooling space meets the heat source placement condition, and control the operation of the rapid cooling fan according to the information. Thus, the rapid cooling control provided by the embodiment of the present disclosure can be upgraded from the rough judgment of "whether there is a heat source" to the refined analysis of "what is the heat source". By identifying the specific attributes of the heat source, the embodiment of the present disclosure can break away from the "one-size-fits-all" air supply mode and instead provide personalized and refined effective air supply according to actual needs. This enables the cold energy resource to be accurately and on-demand delivered to specific targets, fundamentally solves the problem of unreasonable cold energy distribution, greatly improves the refrigeration efficiency, and achieves 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 running according to the heat source information in the rapid cooling space, including: in the case that the number of heat sources in the rapid cooling space is one, the control device controls the rapid cooling fan to start running in a directional air outlet mode; in the case that the number of heat sources in the rapid cooling space is multiple, the control device controls the rapid cooling fan to start running in a variable-direction air outlet mode.

[0206] In this way, the embodiment of the present disclosure can adjust the specific air outlet mode of the rapid cooling fan based on the detected number of heat sources, adopt the directional air outlet mode when there is only one heat source in the rapid cooling space, and adopt the variable-direction air outlet mode when there are multiple heat sources in the rapid cooling space, so as to select the best air supply strategy according to the specific scene, efficiently cool a single heat source, and cooperatively cool multiple heat sources, thereby greatly improving the refrigeration efficiency and cold energy utilization rate.

[0207] Optionally, the heat source information in the rapid cooling space further includes the heat source position; the control device controls the rapid cooling fan to start running in a directional air outlet mode, including: the control device determines a target working angle towards the heat source according to the heat source position; and the control device controls the rapid cooling fan to start running and continuously deliver cold air according to the target working angle.

[0208] In this way, the embodiment of the present disclosure controls the target working angle of the rapid cooling fan by determining the heat source position, so that the cold air can be accurately and directionally delivered to the position where the heat source is located, avoiding the unnecessary diffusion of cold energy, and realizing the real "where the heat source is, where the cold air blows", thereby significantly improving the cooling effect.

[0209] Optionally, the heat source information in the rapid cooling space further includes the heat source size; the control device controls the rapid cooling fan to start running and continuously deliver cold air according to the target working angle, including: the control device determines a target working speed corresponding to the heat source according to the heat source size; and the control device controls the rapid cooling fan to start running and continuously deliver cold air according to the target working angle and the target working speed.

[0210] In this way, the embodiment of the present disclosure can further determine the target working rotating speed of the fan according to the size of the heat source, so as to realize the on-demand matching of the cooling intensity, provide stronger air volume for the large-size heat source, and correspondingly reduce the air volume for the small-size heat source, so as to realize energy saving and noise reduction while ensuring the cooling effect.

[0211] Optionally, the control device determines the target working rotating speed corresponding to the heat source according to the size of the heat source, including: in the case that the size of the heat source is greater than or equal to the first preset size, the control device outputs the first rotating speed instruction to enable the quick cooling fan to operate at a high rotating speed; or in the case that the size of the heat source is less than the first preset size and greater than or equal to the second preset size, the control device outputs the second rotating speed instruction to enable the quick cooling fan to operate at a medium rotating speed; or in the case that the size of the heat source is less than the second preset size, the control device outputs the third rotating speed instruction to enable the quick cooling fan to operate at a low rotating speed.

[0212] In this way, the embodiment of the present disclosure can determine and adjust the working rotating speed of the quick cooling fan in stages according to the size of the heat source in the quick cooling space, so as to realize the on-demand matching of the quick cooling intensity. For the large-size heat source, the system can automatically provide strong air supply at a high rotating speed to ensure rapid cooling; and for the small-size heat source, the system operates at a low rotating speed, so as to avoid unnecessary energy waste and excessive cooling. The gradient intelligent control ensures the accurate correspondence between the cold output and the heat load, and significantly improves the refrigeration efficiency and energy utilization rate.

[0213] Optionally, the heat source information in the quick cooling space further includes heat source positions corresponding to the plurality of heat sources respectively; the control device controls the quick cooling fan to start operating in a variable direction air outlet mode, including: the control device determines a plurality of target working angles respectively facing the plurality of heat sources according to the heat source positions corresponding to the plurality of heat sources respectively; and the control device controls the quick cooling fan to start operating and alternately deliver cold air according to the plurality of target working angles.

[0214] In this way, for the case that a plurality of heat sources exist in the quick cooling space at the same time, the embodiment of the present disclosure can control the quick cooling fan by determining a plurality of target working angles and alternately delivering cold air, so as to ensure that each heat source can be cooled in time and avoid the cooling blind area, thereby improving the use experience in the multi-item storage scenario.

[0215] Optionally, the heat source information in the quick cooling space further includes heat source sizes corresponding to the plurality of heat sources respectively; the control device controls the quick cooling fan to start operating and alternately deliver cold air according to the plurality of target working angles, including: the control device determines a plurality of target working time lengths and / or target working rotating speeds respectively corresponding to the plurality of heat sources according to the heat source sizes corresponding to the plurality of heat sources respectively; and the control device controls the quick cooling fan to start operating and alternately deliver cold air according to the target working angles, the target working time lengths and / or the target working rotating speeds corresponding to the plurality of heat sources respectively.

[0216] Thus, the embodiments of the present disclosure also determine the respective target working time and / or target working rotating speed according to the sizes of the multiple heat sources, realize personalized and refined cooling of the multiple heat sources, ensure that the distribution of cold resources matches the actual heat load of each heat source, and significantly improve the rapid cooling uniformity and energy efficiency.

[0217] Optionally, the control device determines the multiple target working time and / or target working rotating speed corresponding to the multiple heat sources according to the respective heat source sizes of the multiple heat sources, including: in the case that the heat source size is greater than or equal to a first preset size, the control device outputs a first rotating speed instruction and / or a first air supply time; or in the case that the heat source size is less than the first preset size and greater than or equal to a second preset size, the control device outputs a second rotating speed instruction and / or a second air supply time; or in the case that the heat source size is less than the second preset size, the control device outputs a third rotating speed instruction and / or a third air supply time. The first air supply time is greater than the second air supply time, and the second air supply time is greater than the second air supply time.

[0218] Thus, the embodiments of the present disclosure can determine and adjust the target working time and / or target working rotating speed corresponding to each heat source according to the respective heat source sizes of the multiple heat sources, to realize personalized and accurate matching of cooling control of the multiple heat sources. The embodiments of the present disclosure can allocate the most suitable cooling intensity and air supply time to each heat source according to the size of each heat source, for example, provide stronger air supply volume and / or longer air supply time for large-size heat sources, and correspondingly reduce the air supply volume and / or air supply time for small-size heat sources. This ensures that cold resources can be accurately and fairly distributed to each target, fundamentally solves the problem of low efficiency of cold resource distribution in the multiple heat source scenario, and significantly improves the overall refrigeration efficiency and energy utilization rate.

[0219] Optionally, the rapid cooling fan is multiple, and is used for delivering cold air to multiple sub-regions inside the rapid cooling space; the control device controls the rapid cooling fan to start running to guide the cold air to cool the heat source in the rapid cooling space according to the heat source information in the rapid cooling space, including: the control device determines the target rapid cooling fan corresponding to the heat source according to the heat source information in the rapid cooling space; and the control device controls the target rapid cooling fan to start running to guide the cold air to cool the heat source in the sub-region corresponding to the target rapid cooling fan.

[0220] Thus, the embodiments of the present disclosure can realize partitioned rapid cooling through multiple rapid cooling fans, independently provide cold air to different sub-regions, realize real regionalized rapid cooling, and meet the complex storage layout requirements.

[0221] Optionally, the heat source information in the quick cooling space further comprises a heat source position; and the control device determines a target quick cooling fan corresponding to the heat source according to the heat source information in the quick cooling space, including: the control device determines a target sub-region in which the heat source position is located according to the heat source position; and the control device determines the quick cooling fan that delivers cold air to the target sub-region as the target quick cooling fan.

[0222] In this way, the embodiment of the present disclosure can determine the sub-region in which the heat source is located according to the heat source position in the quick cooling space, and further determine the quick cooling fan that delivers cold air to the sub-region as the target quick cooling fan, so that the cold quantity is concentrated on the region around the heat source, and directional cooling is achieved. The embodiment of the present disclosure avoids invalid air supply to non-target regions, reduces overall energy consumption, improves cold air utilization rate and cooling efficiency, and makes the heat source reach the set preservation temperature in the shortest time. When the heat sources are unevenly distributed or the number of heat sources is large, the mapping relationship between the sub-regions and the quick cooling fans can still be relied on to maintain uniform and rapid cold quantity coverage, and the problems of dispersed cold quantity, slow temperature drop and low energy efficiency under the traditional overall air supply mode are significantly improved.

[0223] Based on the above refrigerator, in combination with Figure 12 The embodiment of the present disclosure provides another control method for a refrigerator, including:

[0224] S401, in the case of the refrigerator being powered on and running, the control device acquires a predicted time point at which the user stores a heat source and a current time point.

[0225] S402, in the case that the predicted time point and the current time point satisfy a pre-cooling time condition, the control device controls the temperature sensor to continuously detect the temperature in the quick cooling space.

[0226] S403, in the case that the temperature in the quick cooling space satisfies a pre-cooling temperature condition, the control device controls the quick cooling fan to be pre-started before the predicted time point to pre-cool the quick cooling space.

[0227] The control method for a refrigerator provided by the embodiment of the present disclosure is used in the case that the refrigerator is powered on and running, the predicted time point at which the user stores a heat source is acquired, and the quick cooling fan is pre-started before the time point under the condition that a specific condition is satisfied. Thus, the embodiment of the present disclosure upgrades the traditional “passive response type” quick cooling mode to a “proactive prediction type” pre-cooling mode. Through analysis and prediction of user behavior habits, the embodiment of the present disclosure can pre-cool the quick cooling space before the user puts in a heat source. This fundamentally eliminates the start lag caused by passive response, ensures sufficient cold quantity reserve when the heat source is put in, greatly improves the quick cooling efficiency, and greatly optimizes the user experience.

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

[0229] In this way, the embodiment of the present disclosure can construct a storage time prediction model by using historical time information of the user storing the heat source, and then analyze the predicted time point of the user storing the heat source next time. Based on this, the embodiment of the present disclosure can provide a key self-learning ability for the pre-cooling function, so that the refrigerator can intelligently identify and learn the user's living habits, thereby realizing accurate prediction and advance preparation, and avoiding unnecessary pre-cooling operation.

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

[0231] In this way, the embodiment of the present disclosure can ensure that the pre-cooling function is started within an optimal time window by setting the time difference between the predicted time point and the current time point to satisfy the pre-cooling time condition, thereby avoiding energy waste caused by early start and ensuring sufficient pre-cooling time, so as to realize perfect balance of energy efficiency and effect.

[0232] Optionally, the pre-cooling start duration can be set in combination with the refrigeration temperature in the refrigerator. For example, the pre-cooling start duration can be set to 1 min to ensure that the pre-cooling function is started within an optimal time window, thereby realizing balance of energy efficiency and effect. The pre-cooling start duration can also be adjusted according to actual user needs, and can also be set to any other reasonable value.

[0233] Optionally, the pre-cooling temperature condition includes that the temperature in the quick-cooling space is greater than or equal to a pre-cooling start temperature; and / or, a difference between the temperature in the quick-cooling space and the temperature in the refrigeration compartment is greater than or equal to a pre-cooling start temperature difference.

[0234] In this way, the embodiment of the present disclosure provides specific pre-cooling temperature condition judgment basis for the pre-cooling function, so as to ensure that the quick-cooling fan is started only when pre-cooling is needed (for example, the temperature of the quick-cooling space is too high or the temperature difference with the main refrigeration compartment is too large), thereby further avoiding unnecessary energy consumption.

[0235] Optionally, the pre-cooling start temperature can be set in combination with the refrigeration temperature in the refrigerator. For example, the pre-cooling start temperature can be set to 10℃ to ensure that the quick-cooling fan is started only when pre-cooling is needed, thereby avoiding unnecessary energy consumption. The pre-cooling start temperature can also be adjusted according to actual user needs, and can also be set to any other reasonable value.

[0236] Optionally, the pre-cooling start temperature difference can be set in combination with the in-chamber refrigeration temperature. For example, the pre-cooling start temperature difference can be set to 2°C to ensure that the rapid cooling fan is only pre-started when pre-cooling is needed, avoiding unnecessary energy consumption. The pre-cooling start temperature difference can also be adjusted according to actual user needs, and can also be 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 target heat source information of the heat source stored by the user; the control device determines target pre-cooling parameters of the rapid cooling fan according to the target heat source information; and the control device controls the rapid cooling fan to pre-start according to the target pre-cooling parameters before the predicted time point.

[0238] In this way, the embodiments of the present disclosure can increase the prediction of target heat source information and determine the pre-cooling parameters of the rapid cooling fan that are adapted to the target heat source information, so that the pre-cooling function is not only to pre-ventilate, but also to prepare the most suitable pre-cooling strategy in advance according to the prediction of future heat sources (such as type, size, and position), thereby realizing a more intelligent and personalized pre-cooling experience.

[0239] Optionally, the control device predicts target heat source information of the heat source stored by the user, including: the control device constructs a heat source information prediction model according to historical heat source information of the heat source stored by the user; and the control device determines the target heat source information of the heat source stored by the user on the current day according to the heat source information prediction model.

[0240] In this way, the embodiments of the present disclosure can use the historical heat source information of the heat source stored by the user to construct a heat source information prediction model, and then determine the target heat source information of the heat source that the user is likely to store on the current day. The embodiments of the present disclosure can upgrade the single-dimensional "time prediction" to multi-dimensional "heat source information prediction". By knowing the potential type, size, quantity, position, temperature, and humidity of the heat source in advance before pre-cooling starts, the system can adjust the pre-cooling parameters, such as the pre-set air volume and air direction, according to the characteristics of the heat source, thereby realizing more personalized and precise pre-cooling operations. This ensures that the refrigerator is ready with the most suitable refrigeration conditions when the heat source is put in, significantly improving the pre-cooling efficiency and energy efficiency ratio.

[0241] Optionally, the target heat source information includes a target heat source type; and the control device determines target pre-cooling parameters of the rapid cooling fan according to the target heat source information, including: in the case where the target heat source type is a hot pot, the target pre-cooling parameters of the rapid cooling fan include a first pre-cooling time length and / or a first pre-cooling rotation speed; or in the case where the target heat source type is a beverage, the target pre-cooling parameters of the rapid cooling fan include a second pre-cooling time length and / or a second pre-cooling rotation speed. The first pre-cooling time length is greater than the second pre-cooling time length, and the first pre-cooling rotation speed is greater than the second pre-cooling rotation speed.

[0242] In this way, the embodiments of the present disclosure can dynamically determine the target pre-cooling time length and / or target pre-cooling rotating speed of the rapid cooling fan according to the target heat source type (such as a hot pot or a beverage), so as to upgrade the pre-cooling control from a single dimension of "time prediction" to a more insightful "heat source information prediction". For example, when it is predicted that the user will store a high-heat-load object such as a hot pot, the embodiments of the present disclosure can start the rapid cooling fan in advance and pre-cool for a longer time or at a higher rotating speed to reserve sufficient cold energy. When it is predicted that the user will store a relatively low-heat-load object such as a beverage, the embodiments of the present disclosure can pre-cool for a shorter time or at a lower rotating speed. This ensures that the pre-cooling operation can directly act on the actual heat load of the heat source, fundamentally improves the pre-cooling efficiency and energy efficiency ratio, and realizes more accurate and personalized refrigeration services.

[0243] Optionally, after the control device determines the target pre-cooling parameter of the rapid cooling fan according to the target heat source information, the control device further corrects the target pre-cooling parameter of the rapid cooling fan according to the storage information of the refrigeration compartment.

[0244] In this way, after determining the target pre-cooling parameter of the rapid cooling fan according to the target heat source information, the embodiments of the present disclosure can further adaptively correct the parameter according to the storage information of the refrigeration compartment. By taking the storage amount of the refrigeration compartment into consideration, the embodiments of the present disclosure can more intelligently evaluate the overall heat load and dynamically correct the pre-cooling parameter accordingly, so as to ensure that the pre-cooling effect can meet the rapid response to new heat sources and be coordinated with the current running state of the refrigerator, thereby improving the reliability and energy saving of the control.

[0245] Optionally, the control device corrects the target pre-cooling parameter of the rapid cooling fan according to the storage information of the refrigeration compartment, including: in a case where the storage proportion of the refrigeration compartment is greater than or equal to a first preset proportion, the control device increases the target pre-cooling parameter of the rapid cooling fan; or in a case where the storage proportion of the refrigeration compartment is less than the first preset proportion and greater than a second preset proportion, the control device maintains the target pre-cooling parameter of the rapid cooling fan; or in a case where the storage proportion of the refrigeration compartment is less than or equal to the second preset proportion, the control device decreases the target pre-cooling parameter of the rapid cooling fan. The first preset proportion is greater than the second preset proportion.

[0246] In this way, the embodiments of the present disclosure can divide the storage proportion of the refrigeration compartment into different intervals and correct the target pre-cooling parameter of the rapid cooling fan accordingly to realize dynamic self-adaptation of the pre-cooling intensity. When the storage proportion of the refrigeration compartment is high, the embodiments of the present disclosure can increase the target pre-cooling parameter to compensate for the high heat load and ensure the rapid cooling effect. When the storage proportion of the refrigeration compartment is low, the embodiments of the present disclosure can decrease the target pre-cooling parameter to avoid unnecessary energy consumption. This way of hierarchical correction makes the pre-cooling strategy more accurate and realizes an effective balance between energy efficiency and refrigeration effect.

[0247] Optionally, the control method further comprises: in the case that the temperature in the rapid cooling space does not satisfy the pre-cooling temperature condition, controlling the device to control the rapid cooling fan to stop running; in the case that a refrigerator door opening and closing action is detected, controlling the device to control the temperature sensor to continuously detect the temperature in the rapid cooling space; and controlling the device to control the running state of the rapid cooling fan according to the temperature in the rapid cooling space.

[0248] In this way, when the temperature in the rapid cooling space does not satisfy the pre-cooling temperature condition, the rapid cooling fan stops running, thereby avoiding waste of energy consumption. Meanwhile, the seamless connection of the rapid cooling function is realized by combining the door opening and closing action with temperature feedback, so that the pre-cooling function and the real-time rapid cooling function complement each other, thereby guaranteeing the coherence of user experience and the stability of the system.
