[0059] 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.

[0060] In the process of using the refrigerator, users have the demand for rapidly cooling high-temperature food or rapidly cooling 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 arranged in a refrigeration rapid cooling chamber, a heat preservation sealing cover plate arranged on the upper surface of the rapid cooling drawer, a refrigeration tank air duct partition plate arranged on the lower surface of the rapid cooling drawer, a refrigerator freezing tank arranged on the left side surface of the rapid cooling drawer, a fruit and vegetable box chamber partition plate arranged on the right side surface of the rapid cooling drawer, and a back plate arranged on the back surface of the rapid cooling drawer, wherein 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 rapidly cooling the product to be rapidly cooled to the required temperature in a short time through the cooperation of the rapid cooling drawer in the refrigeration rapid cooling chamber, the independent refrigeration pipeline and the independent air door. The problem of the related art is that the independent refrigeration pipeline is arranged in the drawer, which not only needs to arrange additional components, but also causes energy loss of the cold air in the independent refrigeration pipeline, thereby affecting the rapid cooling effect on the rapid cooling object.

[0061] In order to improve the cooling effect on the rapid cooling object, in combination with Figures 1-8 As shown in the figure, the embodiment of 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, wherein the air guide structure 101 comprises a shell 100, the inside of the shell 100 defines an air guide air duct 140, an air inlet is arranged on the shell 100 close to the first end of the shell 100, the air inlet is adapted to open docking with the cold air forming position of the refrigeration device, and an air outlet 148 is arranged on the shell 100 close to 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 and sends out air from the air outlet when the fan operates to reduce the temperature of the rapid cooling object.

[0062] In the embodiment of 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.

[0063] In the embodiment of the present disclosure, the air inlet of the air guide air duct is the air inlet end of the air guide air duct 140, and the air outlet of the air guide air duct 140 is the air outlet end of the air guide air duct 140.

[0064] The "cold air forming position of the refrigeration device" refers to a position where the formed or blown cold air is lower than the temperature of the refrigeration space 12. For a refrigerator with air cooling, the cold air forming position is the air outlet of the refrigeration space 12; for a refrigerator with direct cooling, the cold air forming position is the position close to the evaporator of the refrigeration space 12.

[0065] The "open docking" is opposite to the traditional "closed docking". If the air inlet end of the air guide duct 140 is closely docked 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 closely docked 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 device, 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. 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. Exemplarily, in the case of a refrigerator being a forced air cooling 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 storage compartment, the 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 of the rapid cooling assembly, and then enters the refrigeration space again through the air outlet of the rapid cooling assembly.

[0066] In the embodiment 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 an 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 open docked with the refrigeration air outlet 14. In the case that the circulating fan 200 is not started, the refrigeration air outlet 14 normally blows 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 inhales 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 faster.

[0067] It should be noted that although 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 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.

[0068] The temperature reduction of the rapid cooling object is mainly based on heat convection, and the efficiency of the temperature reduction 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, the heat convection heat exchange effect of the rapid cooling object is improved, and therefore the temperature reduction speed of the rapid cooling object is improved.

[0069] Compared with the form of "closed docking", the form of open docking has less air volume loss 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 exchange heat with the rapid cooling object by convection at a higher flow rate and a larger flow direction.

[0070] 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 in the cold air blown by the refrigeration air outlet 14 is sucked in 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.

[0071] Compared with the form in which a separate air duct is provided, the rapid cooling assembly 20 provided in the embodiments 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 lower.

[0072] When the temperature of the rapid cooling object is lowered, the use of the rapid cooling assembly 20 disclosed in the present application can improve the flow rate and flow of the cold air blown to the rapid cooling object and lower the temperature of the cold air blown to the rapid cooling object, thereby improving the heat convection exchange effect on the rapid cooling object and improving the cooling rate of the rapid cooling object. 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 provision of an additional air duct and reduce the effect of the rapid cooling assembly 20 on the normal refrigeration effect of the refrigeration space 12 of the refrigeration equipment when the circulating fan 200 is not started.

[0073] 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.

[0074] 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 side 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 have a use form in which the length direction is along the vertical direction. 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.

[0075] The air guide duct 140 needs to pressurize and deliver the cold air from the cold air outlet 14 to the speed object placed in the cold storage space 12. Therefore, the quick cooling assembly 20 needs to have a longer length, and the shell 100 of the quick cooling assembly 20 has the largest size in the length direction. Meanwhile, when the quick cooling assembly 20 is assembled to the cold storage space 12, the influence of the quick cooling assembly 20 on the accommodation capacity of the cold storage space 12 needs to be reduced, and the shell 100 of the quick cooling assembly 20 has a smaller size in the thickness direction. When the circulating fan 200 is arranged, the size of the shell 100 of the quick 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.

[0076] With such an arrangement, the quick cooling assembly 20 has a smaller volume and occupies a smaller space, and the refrigerator will not be significantly affected in accommodation capacity and visual aesthetics when the quick cooling assembly 20 is arranged.

[0077] 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.

[0078] In the case of a centrifugal fan, the thickness of the quick cooling assembly 20 can be made smaller. At the same time, the centrifugal fan also has the advantages of lower cost, reliable function, and larger air volume under the same power.

[0079] When the circulating fan 200 is working, the area where one or both side end surfaces are located serves as the low-pressure suction area 201, and the fan blade at one position in the radial direction cooperates with the fan volute to form a high-pressure blowing outlet. The rotation axis of the fan blade of the circulating fan 200 is in the thickness direction of the shell 100, and there is a predetermined distance between the circulating fan 200 and the inner wall of the shell 100 to form the low-pressure suction area 201, which is an integral whole with the low-pressure suction area 201 of the circulating fan 200 itself.

[0080] Since the circulating fan 200 is located in the air guide duct 140, the partition can separate the fan mounting area 141 and other areas of the air guide duct 140, more specifically, separate the low-pressure suction area 201 and other areas, and the other areas are communicated with the high-pressure blowing outlet of the circulating fan 200. With such an arrangement, the air inlet opening with a smaller suction effect can be formed without significantly increasing the thickness of the quick cooling assembly 20.

[0081] Optionally, the isolation member 210 comprises a foam material 211, which is interposed between the circulating fan 200 and one end surface of the shell 100, and is compressed to isolate the low-pressure suction area 201 and the inclined connecting section 142.

[0082] The foam material 211 not only has a sealing isolation effect, but also can absorb fan vibration. In the case of being assembled by compression, 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 in the vicinity of the circulating fan 200.

[0083] Optionally, one end surface of the shell 100 along the length direction is provided with a first air inlet 221 corresponding to the low-pressure suction area 201.

[0084] In the case of the refrigeration equipment being a wind-cooled refrigerator, 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 221. The first air inlet 221 is closest to the refrigeration forming position, and thus the air guiding effect is more direct. In addition, the first air outlet is located at the end away from the user, and the first air inlet 221 is located at a position not easily observed by the user directly, so that the appearance of the rapid cooling assembly 20 and the refrigeration equipment can be improved.

[0085] Optionally, the downward surface of the shell 100 is provided with a second air inlet 222 corresponding to the low-pressure suction area 201.

[0086] The second air inlet 222 is provided on the downward surface of the shell 100, and in the use state, the second air inlet 222 is located at a position not easily observed by the user directly, so that the appearance of the rapid cooling assembly 20 and the refrigeration equipment can be improved.

[0087] Optionally, the outward surface of the shell 100 is provided with a third air inlet 223 corresponding to the low-pressure suction area 201.

[0088] The outward surface of the shell 100 refers to one end surface of the shell 100 along the thickness direction. In the case that the rapid cooling assembly 20 is attached to the left side wall of the shell 100, the third air inlet 223 is located at 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 be provided with a large area. By adopting such a setting mode, the air inlet area of the rapid cooling assembly 20 can be further improved, so that the air outlet amount of the rapid cooling assembly 20 can be improved.

[0089] Optionally, the outward surface of the shell 100 is provided with an air inlet groove 131 corresponding to the region of the circulating fan 200, the air inlet groove 131 is recessed inward, and a plurality of air inlet grooves 132 are provided in the air inlet groove 131 along a plurality of radial lines; the air inlet groove 131 forms an inclined guide surface from the outside to the inside.

[0090] With such a setting form, the plurality of air inlets 132 can make the front shell 110 have a relatively complete structure, and avoid the particulate matter in the refrigeration space 12 from entering the inside of the rapid cooling assembly 20. The air inlet groove 131 is bowl-shaped, forming a guide surface. When the cold air is discharged from the refrigeration air outlet 14, 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 slope, 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 setting form, the air inlet amount of the rapid cooling assembly 20 is increased.

[0091] Optionally, the rapid cooling assembly 20 comprises an air guide cover plate 130, the air guide cover plate 130 covers the air inlet groove 131, and there is a gap 133 between the periphery of the air guide cover plate 130 and the peripheral wall of the air inlet groove 131, allowing air to enter.

[0092] In the case of setting the air guide cover plate 130, the air guide cover plate 130 can shield the plurality of air inlets 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 is formed between the air guide cover plate 130 and the peripheral wall of the air inlet groove 131, which 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.

[0093] 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 sending section 143, the outlet of the circulating fan 200 is higher or lower than the position of the air sending section 143, and the outlet of the circulating fan 200 is connected to the air sending section 143 through the inclined connecting section 142.

[0094] The fan mounting area 141 is located at the air inlet end of the air guide duct 140. This can increase the air transfer distance of the air sending assembly. The circulating fan 200 is a centrifugal fan, so the air outlet direction tends to be along one tangential direction of the circulating fan 200. The outlet of the circulating fan 200 is higher or lower than the position of the air sending section 143, so that the air blown out from the outlet of the circulating fan 200 can be smoothly and naturally blown to the air sending section 143 through the inclined connecting section 142. With such a setting form, the air volume loss of the air inside the rapid cooling assembly 20 can be reduced.

[0095] Optionally, the air outlet section 143 comprises a conveying portion 144 and a guiding portion 146. The conveying portion 144 extends along the length direction of the housing 100 and has an air outlet opening downward. The guiding portion 146 extends along the length direction of the air outlet opening and forms a guiding slope. The cold air blown out from the air outlet opening of the conveying portion 144 is guided by the guiding slope to blow out obliquely downward through the air outlet.

[0096] The air outlet opening of the conveying portion 144 of the air outlet section 143 is downward, and the guiding portion 146 extends along the length direction of the air outlet opening and forms a guiding slope. When the air is blown out from the conveying portion 144, the air is guided by the guiding slope to blow out obliquely downward. In this way, the cold air is blown out from a lower position. The cold air can be better exchanged 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 is increased during the heat exchange and moves upward. In this way, the circulation of the cold air 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 is improved.

[0097] In addition, the air outlet opening of the conveying portion 144 downward and the inclined guiding slope make the internal structure of the quick-cooling assembly 20 not easy to be observed by the user, so that the appearance of the quick-cooling assembly 20 and the refrigeration equipment can be further improved.

[0098] Optionally, the quick-cooling assembly 20 further comprises a lighting module 300. The lighting module 300 is arranged on the inner top wall of the conveying portion 144, and the lighting direction of the lighting module 300 is toward the guiding portion 146 so that the guiding portion 146 has a light-emitting effect.

[0099] 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 toward the guiding portion 146. The projection of the inclined guiding slope 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 guiding slope. For example, the light emitted by the lighting module 300 covers more than 95% of the area of the guiding slope. In addition, when the lighting module 300 emits light, the light is constrained by the two side walls of the conveying portion 144 along the thickness direction of the quick-cooling assembly 20, and can only irradiate the inclined guiding slope below the air outlet opening of the conveying portion 144. When the lighting module 300 emits light to illuminate the guiding slope, the light emitted by the lighting module 300 cannot irradiate other positions of the refrigerating compartment 12.

[0100] The illumination module 300 is in the form of an inner top wall of the conveying portion 144, which can reduce or avoid the accumulation of condensed water on the illumination module 300, and improve the safety of the quick cooling module. In addition, the light emitted by the illumination module 300 can be further constrained by the two opposite side walls of the conveying portion 144, so that it can only illuminate the air guide slope. With such a setting form, the illumination module 300 is invisible, and the light emitted by the illumination module 300 will not leak. In this way, the visual effect of the quick cooling assembly 20 can be further improved, and the science and technology of the quick cooling assembly 20 and the appearance of the refrigeration equipment can be improved. The illumination module is arranged in the form of the quick cooling assembly, and the illumination module can be maintained by removing or opening the quick cooling assembly, thereby improving the maintenance convenience of the illumination module.

[0101] Optionally, the inner top wall of the conveying portion 144 is upwardly recessed to form a mounting space, and the illumination module 300 is embedded in the mounting space, and a downward side of the illumination module 300 is smoothly connected with the inclined connecting section 142.

[0102] In this case, after the illumination module 300 is installed, the transition of the inclined connecting section 142 and the air sending section 143 is relatively smooth, which can reduce the wind loss inside the quick cooling assembly 20.

[0103] 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.

[0104] The air outlet is a long and narrow air outlet, and the length of the air outlet is greater than the height of the air outlet. 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.

[0105] The length of the air guide portion 146 is equal to the length of the air outlet, so that the full coverage of the air guide downwardly can be achieved. When the illumination module 300 emits light, the light emitting effect of the air guide slope covers the entire length of the air outlet. With such a setting form, the quick cooling assembly 20 and the light display effect can be further improved, and the display effect of the refrigeration equipment can be improved.

[0106] Optionally, the two opposite side walls of the air sending section 143 are arranged in parallel, and the light emitted by the illumination module 300 is constrained by the two parallel side walls and is illuminated to the air guide slope.

[0107] The thickness of the air outlet section 143 is equal from top to bottom, in this case, when the lighting module 300 emits light, the light downwardly irradiated is in the form of approximately parallel light, the light irradiates to the air guide slope, 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 slope of the rapid cooling assembly 20.

[0108] 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 circumferential side of the light source plate 310 and the light homogenizing plate 320.

[0109] 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 slope. The light shielding material 330 covers the circumferential side of the light source plate 310 and the light homogenizing plate 320, which can reduce or avoid the light leakage of the lighting module 300. Especially near the shell 100 of the lighting module 300, the light is not easy to penetrate the side wall of the shell 100 to form a bright band. In addition, the light shielding material 330 covering the circumferential side of the light source plate 310 and the light homogenizing plate 320 can also improve the overall waterproof capability of the lighting module 300.

[0110] Optionally, the light shielding material 330 is aluminum foil. In this way, not only is the assembly of the lighting module 300 facilitated, but the aluminum foil also has good light shielding property and good waterproof property. With this setting form, the waterproof capability and the light leakage prevention capability of the lighting module 300 are further improved.

[0111] Optionally, the shell 100 comprises a rear shell 120 and a front shell 110, wherein the rear shell 120 is recessed on one side to form an air outlet recess 121 and recessed on the other side to form a wiring space 122; the front shell 110 is combined with the rear shell 120, the front shell 110 is combined to the air outlet recess 121 to form an air guide duct 140, and the front shell 110 is provided with an air outlet; wherein the air guide portion 146 is an integral structure with the rear shell 120, or the air guide portion 146 is an integral structure with the front shell 110.

[0112] The rear shell 120 is connected to the inner wall of the refrigeration device. One side of the rear shell 120 facing the refrigeration space 12 is recessed in a direction away from the refrigeration space 12 to form an air outlet recess 121, and the other side of the rear shell 120 facing away from the refrigeration space 12 is recessed in a direction close to the refrigeration space 12 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 covers the air outlet recess 121 of the rear shell 120, and the air outlet recess 121 forms an air guide duct 140. The front shell 110 has an air outlet on the side facing the refrigeration space 12. The air guide portion 146 is in one-piece 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.

[0113] With such an arrangement, 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.

[0114] Optionally, the air guide duct 140 includes a fan mounting area 141, an inclined connecting section 142 and an air delivery 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 delivery section 143; the rapid cooling assembly 20 further includes a circulating fan 200, which is arranged in the fan mounting area 141, and the outlet of the circulating fan 200 is connected to the air delivery section 143 through the inclined connecting section 142.

[0115] Optionally, the shell 100 has a temperature detection hole 124 on the same side as the air outlet, and the shell 100 has a temperature detection area 125 inside corresponding to the temperature detection hole 124, which is isolated from the air guide duct 140; the rapid cooling assembly 20 further includes an infrared temperature sensor 400, which 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.

[0116] The temperature detection hole 124, the third air inlet 223 and the air outlet are all arranged on the outer side of the shell 100. The shell 100 has a temperature detection area 125 inside, which is isolated from the air guide duct 140, so that the detection of the infrared temperature sensor 400 is not affected. 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 to determine the fan speed according to the temperature of the rapid cooling object. The infrared temperature sensor 400 detects the background temperature, which can determine whether the temperature in the area corresponding to the infrared temperature sensor 400 is too high or too low, thereby controlling the start and stop of the rapid cooling assembly 20.

[0117] With such a setting mode, the infrared temperature sensor 400 is beneficial to identify the temperature of the rapid cooling object, and provide a decision basis for the start-stop and rotating speed of the circulating fan.

[0118] Optionally, the rapid cooling assembly 20 further comprises a battery 510 arranged in the shell 100.

[0119] In the case that the rapid cooling assembly 20 further comprises the battery 510, the rapid cooling assembly 20 can drive the circulating fan 200 to rotate without the power supply of the refrigerator. In this way, not only the installation position of the rapid cooling assembly 20 is not limited by the wiring harness connection, but also the rapid cooling assembly 20 can be adapted to different forms of refrigerators. The rapid cooling assembly 20 is built-in with the battery 510, and after being assembled to a refrigerator without rapid cooling function, the refrigerator can also be endowed with the rapid cooling function.

[0120] Optionally, the rapid cooling assembly 20 further comprises a manual switch connected to the circulating fan 200.

[0121] 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.

[0122] Optionally, the rapid cooling assembly 20 further comprises a battery 510 and a timing switch 520 connected to the circulating fan 200.

[0123] 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.

[0124] In combination Figures 1-8 As shown in the figure, the embodiment of the present disclosure provides a refrigerator, which comprises a cabinet 10 and the above-mentioned rapid cooling assembly 20.

The rapid cooling assembly 20 is mounted on the side wall of the refrigeration space 12, the air inlet of the rapid cooling assembly 20 is open to the refrigeration air outlet 14, and the air outlet of the rapid cooling assembly 20 faces the rapid cooling object placed in the refrigeration space 12.

[0125] The refrigerator comprises 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 installed on the left side wall or the right side wall of the refrigeration space 12, the rapid cooling assembly 20 is installed transversely, the air inlet is located at one end close to the rear wall of the refrigeration space 12, and the air outlet faces the rapid cooling object in the refrigeration space 12.

[0126] 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 the 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, flow volume and temperature of the cold air blown to the rapid cooling object can be improved 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 in the form of open docking 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.

[0127] Optionally, one rapid cooling assembly 20 is arranged on the left side wall and the right side wall of the refrigeration space 12 respectively.

[0128] By adopting the above-mentioned arrangement form, the cooling speed of the rapid cooling object can be further improved.

[0129] Optionally, the rapid cooling assembly 20 is detachable and is assembled to the inner wall of the refrigeration space 12.

[0130] The inner wall of the refrigeration space comprises 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 cabinet, the top side wall of the refrigeration space further comprises a downward side of the partition plate, or the bottom side wall of the refrigeration space further comprises an upward side of the partition plate.

[0131] By using the refrigerator provided by the embodiment of the present application, the rapid cooling assembly 20 is arranged, the temperature of the rapid cooling object in a region of the refrigeration space 12 can be quickly reduced; the rapid cooling assembly 20 is in a detachable form, the rapid cooling assembly 20 can be assembled to different layers or different regions of the refrigeration space 12 according to actual needs, the rapid cooling efficiency is improved, and the user is facilitated.

[0132] 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.

[0133] The quick cooling assembly 20 is provided with a suction disc 530 which can be adsorbed to the smooth inner wall of the refrigeration space 12. When the quick cooling object needs to be cooled, the quick cooling assembly 20 is adsorbed to the designated area. When the position is changed, the suction disc 530 is depressurized and the quick cooling assembly 20 can be conveniently taken down. With such a setting mode, the quick cooling assembly 20 is easy to disassemble and has a low cost.

[0134] Optionally, the suction disc 530 of the quick cooling assembly 20 is at least partially located inside the shell 100.

[0135] As an optional embodiment, the shell 100 of the quick cooling assembly 20 is constructed with an adsorption groove, and the suction disc 530 is arranged in the adsorption groove. In this way, after the quick cooling assembly 20 is assembled to the refrigeration space 12, the quick cooling assembly 20 as a whole does not protrude too much from the inner wall of the cabinet 10, so that the appearance of the refrigerator can be improved and the impact on the storage capacity of the refrigeration space 12 caused by the setting of the quick cooling assembly 20 can be reduced.

[0136] Optionally, the sidewall of the cabinet 10 is provided with a first magnetic attraction member 15, and the quick cooling assembly 20 comprises a second magnetic attraction member 540, and the first magnetic attraction member 15 cooperates with the second magnetic attraction member 540 to fix the quick cooling assembly 20 to the inner wall of the refrigeration space 12.

[0137] As an optional embodiment, the inner liner 11 of the refrigeration space 12 is a metal inner liner 11 which serves as the first magnetic attraction member 15. The quick cooling assembly 20 is provided with a magnet which serves as the second magnetic attraction member 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 member 15. The quick cooling assembly 20 is provided with a magnet which serves as the second magnetic attraction member 540. The quick cooling assembly 20 is disassembled in the form of cooperation between the first magnetic attraction member 15 and the second magnetic attraction member 540, which not only further facilitates the use of the user, but also can optimize the feel of disassembling the quick cooling assembly 20.

[0138] Optionally, the sidewall of the cabinet 10 is provided with a first cooperation member 16, and the quick cooling assembly 20 comprises a second cooperation member 550, and the first cooperation member 16 cooperates with the second cooperation member 550 to fix the quick cooling assembly 20 to the inner wall of the refrigeration space 12.

[0139] As an optional embodiment, the first cooperation member 16 is a screw hole, and the second cooperation 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 a setting mode, 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.

[0140] 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 matching part. The quick cooling assembly 20 is fixed to the inner wall of the refrigeration space 12 in the form of clamping. With such a setting mode, the quick cooling assembly 20 can be accurately positioned to the installation position, which is beneficial to the realization of the quick cooling function of the quick cooling assembly 20.

[0141] Optionally, the box body 10 comprises the inner container 11 and the air duct assembly 13, wherein the inner container 11 defines the refrigeration space 12; and 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 air outlet of the refrigeration air duct faces the left and right side walls.

[0142] 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 air, cold air is blown to the left and right side walls of the inner container 11. With such a setting form, when the refrigerator is opened, the refrigeration air outlet will not blow directly to the user, reducing the loss of cold quantity and improving the user's experience. In the case that the air duct assembly 13 blows air to 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. In this way, the quick cooling function and the ordinary refrigeration function of the refrigerator can be clearly distinguished.

[0143] 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.

[0144] The rear wall of the refrigeration space 12 is in front of the air duct assembly 13. In the case that the air inlet of the quick cooling assembly 20 and the refrigeration air outlet 14 are open and connected, if the distance between the air inlet and the refrigeration air outlet 14 is too small, it is difficult for the quick cooling assembly 20 to suck in cold air, 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 is mostly the air in the refrigeration space 12, and the temperature of the air outlet of the quick cooling assembly 20 is relatively high, 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 10 mm and 50 mm, so that the quick cooling assembly 20 can suck in more cold air, and the sucked cold air is at the position of the cold air output by 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.

[0145] 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.

[0146] In this case, the user can place the quick cooling assembly 20 in the position where the wireless charging coil is located to charge the quick cooling assembly 20, and the charging of the quick cooling assembly 20 is also completed in the refrigerating space 12. In this way, the convenience of using the quick cooling assembly 20 can be further improved.

[0147] Optionally, the refrigerator forms a quick cooling area 17 in the refrigerating space 12, and the quick cooling assembly 20 is arranged in the quick cooling area 17.

[0148] With such an arrangement, the refrigerator can achieve zoned cooling of different areas of the refrigerating space.

[0149] In the subsequent description, the "quick cooling area" and the "quick cooling space" are the same terms. The "refrigerating space" and the "refrigerating chamber" are also the same terms.

[0150] Optionally, in combination with Figure 9 As shown in the figure, the refrigerator further includes a control device configured for a control method of the refrigerator, and the method includes:

[0151] S101, in the case where the opening and closing door action of the refrigerator is detected, the control device controls the temperature sensor to continuously detect the temperature in the quick cooling area.

[0152] S102, the control device controls the operating state of the circulating fan according to the temperature in the quick cooling area.

[0153] The control method for the refrigerator provided by the embodiment of the present disclosure takes the opening and closing door action of the refrigerator as one of the trigger conditions, and continuously detects the local temperature in the quick cooling area under this condition, and then controls the operating state of the circulating fan according to the temperature. Therefore, the embodiment of the present disclosure creates a direct and efficient quick cooling trigger mechanism, which can rapidly perceive and respond at the first time when the heat source is put in by linking the specific human-computer interaction with the local temperature change. This fundamentally overcomes the response lag of the traditional passive control, ensures that the cold energy resource is delivered in time when it is most needed, and significantly improves the cooling efficiency of the heat source.

[0154] Optionally, the control device controls the operating state of the circulating fan according to the temperature in the quick cooling area, including: in the case where the temperature in the quick cooling area meets the heat source putting-in condition, the control device controls the circulating fan to start running to guide the cold air to cool the heat source in the quick cooling area; and in the case where the temperature in the quick cooling area meets the heat source temperature reaching condition, the control device controls the circulating fan to stop running to stop guiding the cold air to cool the heat source in the quick cooling area.

[0155] In this way, the embodiment of the present disclosure can start the circulating fan when the temperature in the rapid cooling area meets the heat source placement condition, and stop the circulating fan when the temperature in the rapid cooling area meets the heat source temperature reaching condition, thereby constructing a complete rapid cooling function closed-loop control logic, and realizing on-demand operation of the circulating fan, avoiding unnecessary long-time operation, and effectively reducing energy consumption.

[0156] Optionally, the heat source placement condition comprises: the temperature in the rapid cooling area is greater than or equal to a preset start temperature; and the temperature change rate in the rapid cooling area is greater than or equal to a preset temperature change rate.

[0157] In this way, the embodiment of the present disclosure can use the temperature and the temperature change rate in the rapid cooling area to determine the heat source placement condition, overcome the misjudgment defect caused by single dimension judgment, accurately identify the real heat source placement event, effectively exclude the misjudgment 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.

[0158] Optionally, the preset start temperature can be set in combination with the refrigeration temperature in the box. For example, the preset start temperature can be set to 10℃, to exclude the misjudgment caused by taking out the heat source before closing the door, and identify the real heat source placement event. The preset start temperature can also be adjusted according to actual user needs, and can also be set to other arbitrary reasonable values.

[0159] Optionally, the preset temperature change rate can be set in combination with the difference between the ambient temperature outside the box and the refrigeration temperature in the box. For example, the preset temperature change rate can be set to 2℃ / s, to exclude the misjudgment caused by taking out the heat source by hand, and 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 other arbitrary reasonable values.

[0160] Optionally, the temperature in the rapid cooling area comprises the heat source temperature and the ambient temperature; the heat source temperature reaching condition comprises: the heat source temperature in the rapid cooling area 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 area is less than or equal to a preset shutdown temperature difference; and / or, the continuous running time of the circulating fan is greater than or equal to a preset running time.

[0161] In this way, the embodiment of the present disclosure can use multiple heat source temperature reaching conditions for combined determination, including whether the heat source temperature in the rapid cooling area 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 judgment bases for accurate stopping of the rapid cooling function, which not only ensures that the heat source is sufficiently cooled, but also stops running in time, avoids excessive refrigeration, and ensures energy efficiency.

[0162] Optionally, the preset shutdown temperature can be set in combination with the refrigeration temperature in the box. For example, the preset shutdown temperature can be set to 6°C to ensure that the heat source is sufficiently cooled to accurately stop the rapid cooling function. The preset shutdown temperature can also be adjusted according to the actual needs of the user, and can also be set to any other reasonable value.

[0163] Optionally, the preset shutdown temperature difference can be set in combination with the refrigeration temperature in the box. For example, the preset shutdown temperature difference can be set to 2°C to ensure that the heat source is sufficiently cooled to accurately stop the rapid cooling function. The preset shutdown temperature difference can also be adjusted according to the actual needs of the user, and can also be set to any other reasonable value.

[0164] Optionally, the preset running duration can be set in combination with the refrigeration temperature in the box. For example, the preset running duration can be set to 12h to ensure that the heat source is sufficiently cooled to accurately stop the rapid cooling function. The preset running duration can also be adjusted according to the actual needs of the user, and can also be set to any other reasonable value.

[0165] Optionally, the temperature in the rapid cooling area includes the heat source temperature and the ambient temperature; after the control device controls the circulating fan to start running, the control device further adjusts the working speed of the circulating fan according to the heat source temperature in the rapid cooling area. The working speed of the circulating fan is positively correlated with the heat source temperature in the rapid cooling area.

[0166] In this way, the disclosed embodiments can establish a positive correlation between the working speed of the circulating fan and the heat source temperature in the rapid cooling area, 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 circulating fan set accordingly, and the stronger the corresponding cold energy delivery to the rapid cooling area, thereby improving the rapid cooling efficiency, shortening the cooling time, and optimizing the on-demand allocation of energy.

[0167] Optionally, the control device adjusts the working speed of the circulating fan according to the heat source temperature in the rapid cooling area, including: when the heat source temperature in the rapid cooling area is greater than a first heat source temperature threshold, the control device outputs a first speed instruction to make the circulating fan run at a high speed; or when the heat source temperature in the rapid cooling area 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 make the circulating fan run at a medium speed; or when the heat source temperature in the rapid cooling area 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 make the circulating fan run at a low speed.

[0168] In this way, the embodiment of the present disclosure can segmentally adjust the working speed of the circulating fan according to the heat source temperature in the rapid cooling area, so as to realize on-demand matching of the rapid cooling intensity. When the heat source temperature is high, the fan runs at a high speed to rapidly cool down; when the temperature gradually decreases, the fan speed is also lowered accordingly, thereby avoiding unnecessary energy waste. This gradient intelligent control ensures accurate correspondence between the cooling capacity output and the heat load, and significantly improves the refrigeration efficiency and energy utilization rate.

[0169] Optionally, after the control device controls the circulating fan to start running, the method further comprises: the control device acquires the working gear of the refrigeration compartment; and the control device adjusts the working speed of the circulating fan according to the working gear of the refrigeration compartment. The working speed of the circulating fan is negatively correlated with the target refrigeration temperature corresponding to the working gear.

[0170] In this way, the embodiment of the present disclosure can establish a negative correlation between the working speed of the circulating fan and the working gear of the refrigeration compartment, so that the local rapid cooling function is coordinated with the overall refrigeration strategy of the refrigerator. That is, the stronger the working gear is, the lower the target refrigeration temperature is, and the greater the working speed of the circulating fan set accordingly is, and the stronger the cooling capacity delivery corresponding to the rapid cooling area is, thereby ensuring that the circulating fan always runs at the most suitable speed under different main working gears, and taking into account the rapid cooling effect and overall refrigeration effect of the refrigerator, and ensuring that the rapid cooling area is always in an efficient and energy-saving running state at different refrigeration temperatures.

[0171] Optionally, the control device adjusts the working speed of the circulating fan according to the working gear of the refrigeration compartment, comprising: in the case that the target refrigeration temperature corresponding to the working gear of the refrigeration compartment is less than a first refrigeration temperature threshold, the control device outputs a first speed instruction to make the circulating fan run at a high speed; or in the case that the target refrigeration temperature corresponding to the working gear 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 make the circulating fan run at a medium speed; or in the case that the target refrigeration temperature corresponding to the working gear of the refrigeration compartment is greater than or equal to the second refrigeration temperature threshold, the control device outputs a third speed instruction to make the circulating fan run at a low speed.

[0172] In this way, the embodiment of the present disclosure can dynamically adjust the working speed of the circulating fan according to the working gear of the refrigeration compartment, so as to deeply integrate the local rapid cooling function with the overall operation strategy of the refrigerator. By linking the speed of the circulating fan with the refrigeration temperature gear set by the user, the system can ensure that the rapid cooling operation always keeps consistent with the overall refrigeration target of the refrigerator, for example, the rapid cooling intensity is reduced accordingly in the energy-saving gear. This not only maintains the overall stability of the temperature inside the refrigerator, but also avoids additional energy consumption caused by function conflicts.

[0173] Optionally, the control method further comprises: in the case that the temperature in the rapid cooling area meets the heat source placement condition, the control device controls the atmosphere lamp to start running to prompt the user that the cold air is cooling the heat source in the rapid cooling area.

[0174] In this way, the embodiments of the present disclosure can provide intuitive function state prompts for the user through the start of the atmosphere lamp, enhance the friendliness of human-computer interaction, enable the user to clearly perceive the start of the rapid cooling function, and improve the user experience.

[0175] Optionally, after the control device controls the atmosphere lamp to start running, the method further comprises: in the case that the refrigerator door is open, the control device adjusts the working brightness of the atmosphere lamp according to the working speed of the circulating fan. The working brightness of the atmosphere lamp is positively correlated with the working speed of the circulating fan.

[0176] In this way, when the refrigerator door is open, the embodiments of the present disclosure can provide an intuitive and dynamic visual feedback for the user by adjusting the working brightness of the atmosphere lamp. When the circulating fan runs at a high speed, the brightness of the atmosphere lamp is increased, which intuitively shows the user that the system is performing a powerful cooling. This makes the originally invisible rapid cooling process visualized, improves the user experience and the friendliness of human-computer interaction.

[0177] Optionally, after the control device controls the atmosphere lamp to start running, the method further comprises: in the case that the refrigerator door is closed, the control device controls the atmosphere lamp to be turned off.

[0178] In this way, when the refrigerator door is closed, the user cannot see the atmosphere lamp, and turning off the light at this time can save energy and meet the user's use logic. Therefore, the embodiments of the present disclosure can directly turn off the atmosphere lamp to achieve on-demand control of the atmosphere lamp.

[0179] Optionally, in combination with Figure 10 As shown in the figure, the control device is further configured to perform the following control method for the refrigerator, and the method comprises:

[0180] S201, in the case that the refrigerator door opening and closing action is detected, the control device controls the temperature sensor to continuously detect the temperature in the rapid cooling area.

[0181] S202, in the case that the temperature in the rapid cooling area meets the heat source placement condition, the control device controls the circulating fan to start running to guide the cold air to cool the heat source in the rapid cooling area.

[0182] S203, in the case that the temperature in the rapid cooling area meets the heat source frost condition, the control device controls the circulating fan to intermittently run to avoid the heat source in the rapid cooling area from frosting.

[0183] The control method for the refrigerator provided by the embodiment of the present disclosure can control the circulating fan to intermittently operate in the case that the temperature in the rapid cooling area meets the heat source frosting condition, so as to avoid heat source frosting. Therefore, the embodiment of the present disclosure can guarantee the rapid cooling effect while effectively avoiding the frosting risk caused by excessive refrigeration. Through the short fan stop, the system can allow the local temperature of the heat source surface or its surroundings 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-frosting control realizes the "soft landing" in the rapid cooling process, and balances the refrigeration efficiency and food safety.

[0184] Optionally, the heat source placement condition comprises: the temperature in the rapid cooling area is greater than or equal to a preset start temperature; and the temperature change rate in the rapid cooling area is greater than or equal to a preset temperature change rate.

[0185] In this way, the embodiment of the present disclosure can use the temperature and the temperature change rate in the rapid cooling area 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 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.

[0186] Optionally, the temperature in the rapid cooling area comprises a heat source temperature and an environment temperature; and the heat source frosting condition comprises: the environment temperature in the rapid cooling area is less than or equal to a first frosting temperature; and / or, the heat source temperature in the rapid cooling area is less than or equal to a second frosting temperature.

[0187] In this way, the embodiment of the present disclosure includes the environment temperature and / or the heat source temperature in the rapid cooling area in the frosting judgment, so that the frosting risk point can be more accurately grasped, to ensure that the circulating fan only starts intermittent operation when there is a frosting risk, and realizes fine anti-frosting control.

[0188] Optionally, the first frosting temperature can be set in combination with the refrigeration temperature in the refrigerator. For example, the first frosting temperature can be set to 0℃, to more accurately grasp the frosting risk point, and thus realize fine anti-frosting control. The first frosting temperature can also be adjusted according to the actual needs of the user, and can also be set to any other reasonable value.

[0189] Optionally, the second frosting temperature can be set in combination with the refrigeration temperature in the refrigerator. For example, the second frosting temperature can be set to 2℃, to more accurately grasp the frosting risk point, and thus realize fine anti-frosting control. The second frosting temperature can also be adjusted according to the actual needs of the user, and can also be set to any other reasonable value.

[0190] Optionally, the control device controls the circulating fan to operate intermittently, including: the control device repeatedly performing the following steps until the temperature in the rapid cooling zone does not meet the frost conditions of the heat source: the control device controls the circulating fan to start running for a first duration; the control device controls the circulating fan to stop running for a second duration.

[0191] Thus, the embodiments of this disclosure can control the circulating fan to alternate between a first running period and a second running period, thereby achieving intermittent operation. This allows the local temperature to rise briefly by stopping the air supply while continuously cooling the heat source, effectively preventing frost formation.

[0192] Optionally, the initial cooling time can be set in conjunction with the internal refrigeration temperature. For example, the initial cooling time can be set to 1 minute to ensure rapid cooling and thus improve food storage performance. The initial cooling time can also be adjusted according to the user's actual needs or set to any other reasonable value.

[0193] Optionally, the second duration can be set in conjunction with the internal refrigeration temperature. For example, the second duration can be set to 1 minute to allow the local temperature to rise, thereby effectively preventing frost formation. The second duration can also be adjusted according to the user's actual needs or set to any other reasonable value.

[0194] Optionally, the control device cyclically executes the following steps until the temperature in the rapid cooling area does not meet the frost conditions of the heat source, further including: the control device determining heat source information in the rapid cooling area; the control device determining a first duration and a second duration based on the heat source information in the rapid cooling area.

[0195] Thus, in this embodiment of the present disclosure, before executing intermittent operation, the heat source information within the rapid cooling area is determined, and a first duration and a second duration are determined based on this information. This embodiment of the present disclosure can transform the control of intermittent operation from a fixed timing sequence to dynamic adaptation. By analyzing the specific information of the heat source, the system can configure the optimal intermittent cycle for different types of heat sources, such as extending the operating time for high-temperature heat sources or low-humidity heat sources, thereby effectively achieving rapid cooling while precisely controlling the frost prevention rhythm, improving the overall efficiency and accuracy of the solution.

[0196] Optionally, the heat source information within the rapid cooling zone includes the heat source temperature; the control device determines a first duration and a second duration based on the heat source information within the rapid cooling zone, including: when the heat source temperature within the rapid cooling zone is greater than or equal to a preset heat source temperature, the control device determines the first duration to be T. 11 The second duration is determined to be T. 21 Alternatively, if the heat source temperature in the rapid cooling zone is lower than the preset heat source temperature, the control device determines the first duration to be T. 12 The second duration is determined to be T.22 wherein T 11 +T 21 =T 12 +T 22 , T 11 / T 21 >T 12 / T 22 .

[0197] In this way, when the heat source temperature is high, the disclosed embodiments assign a larger run / stop duration ratio (T 11 / T 21 ) to ensure that, while preventing frost, more sustained and powerful cold output can be provided to improve the rapid cooling efficiency. This ensures that the control strategy can match the actual cooling demand of the heat source, achieving a balance between efficiency and effectiveness.

[0198] Optionally, the heat source information in the rapid cooling area includes heat source humidity; the control device determines the first duration and the second duration according to the heat source information in the rapid cooling area, including: in the case that the heat source humidity in the rapid cooling area is greater than or equal to a preset heat source humidity, the control device determines the first duration as T 13 and the second duration as T 23 ; or, in the case that the heat source humidity in the rapid cooling area is less than the preset heat source humidity, the control device determines the first duration as T 14 and the second duration as T 24 . Wherein T 13 +T 23 =T 14 +T 24 , T 13 / T 23 <T 14 / T 24 .

[0199] In this way, when the heat source humidity is high, since the heat source with high water content is more prone to water vapor and frost, the disclosed embodiments assign a smaller run / stop duration ratio (T 13 / T 23 ) to it, meaning that the fan will stop more frequently, thereby effectively preventing water vapor from condensing into frost at the source. This ensures that the frost prevention strategy can directly act on the root cause of frost, providing efficient and energy-saving frost protection.

[0200] Optionally, the control method further includes: in the case that the temperature in the rapid cooling area meets the heat source frost condition, the control device acquires a continuous frost duration; in the case that the continuous frost duration is greater than or equal to a preset frost duration, the control device controls the circulating fan to stop running to stop guiding the cold air to cool the heat source in the rapid cooling area.

[0201] In this way, the embodiments of the present disclosure can further determine the duration of continuous frost when there is a frost risk, thereby forming a double insurance mechanism. If the frost problem cannot be solved by intermittent operation of the circulating fan for a period of time, the system will forcibly stop the circulating fan to maximize food safety and prevent the risk of freezing damage in extreme cases.

[0202] 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.

[0203] Optionally, the control method further includes: in a case where the temperature in the rapid cooling area meets the heat source temperature reaching condition, the control device controls the circulating fan to stop running to stop guiding the cold air to cool the heat source in the rapid cooling area.

[0204] In this way, in combination with the heat source temperature reaching condition, the embodiments of the present disclosure can ensure that the function is exited in time after the rapid cooling is completed, thereby avoiding waste of cold energy and preventing long-term high-load operation of the fan.

[0205] Optionally, the temperature in the rapid cooling area includes the heat source temperature and the ambient temperature; the heat source temperature reaching condition includes: the heat source temperature in the rapid cooling area is less than or equal to a preset shutdown temperature; and / or, the difference between the heat source temperature in the rapid cooling area and the ambient temperature is less than or equal to a preset temperature difference; and / or, the continuous running duration of the circulating fan is greater than or equal to a preset running duration.

[0206] 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 area is low, whether the temperature difference between the heat source temperature and the ambient temperature is small, and whether the continuous running duration 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.

[0207] Optionally, in combination with Figure 11 As shown in the figure, the control device is further configured to execute the following control method, the method comprising:

[0208] S301, in a case where a refrigerator door opening action is detected, the control device controls the temperature sensor to continuously detect the temperature in the rapid cooling area.

[0209] S302, in a case where the temperature in the rapid cooling area meets the heat source putting-in condition, the control device determines the heat source information in the rapid cooling area.

[0210] S303, the control device controls the circulating fan to start running according to the heat source information in the quick cooling area to guide the cold air to cool the heat source in the quick cooling area.

[0211] 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 quick cooling area meets the heat source putting-in condition, and control the operation of the circulating fan according to the information. Thus, the embodiment of the present disclosure can improve the quick cooling control from the extensive 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 system can get rid of 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 resources 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 effect.

[0212] Optionally, the heat source information in the quick cooling area includes the number of heat sources; the control device controls the circulating fan to start running according to the heat source information in the quick cooling area, including: in the case that the number of heat sources in the quick cooling area is one, the control device controls the circulating fan to start running in a directional air outlet mode; in the case that the number of heat sources in the quick cooling area is multiple, the control device controls the circulating fan to start running in a variable direction air outlet mode.

[0213] In this way, the embodiment of the present disclosure can adjust the specific air outlet mode of the circulating fan based on the detected number of heat sources, adopt the directional air outlet mode when there is only one heat source in the quick cooling area, and adopt the variable direction air outlet mode when there are multiple heat sources in the quick cooling area, so as to select the best air supply strategy according to the specific scene, efficiently and centrally cool a single heat source, and cooperatively cool multiple heat sources, greatly improving the refrigeration efficiency and cold energy utilization rate.

[0214] Optionally, the heat source information in the quick cooling area further includes the heat source position; the control device controls the circulating 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 circulating fan to start running and continuously deliver cold air according to the target working angle.

[0215] In this way, the embodiment of the present disclosure controls the target working angle of the circulating 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", which significantly improves the cooling effect.

[0216] Optionally, the heat source information in the rapid cooling area further comprises a heat source size; the control device controls the circulating fan to start running and continuously deliver cold air according to the target working angle, comprising: the control device determines the target working speed corresponding to the heat source according to the heat source size; the control device controls the circulating fan to start running and continuously deliver cold air according to the target working angle and the target working speed.

[0217] In this way, the target working speed of the fan can be determined according to the heat source size, so that the cooling intensity can be matched as needed, stronger air volume is provided for a large-size heat source, and the air volume is reduced for a small-size heat source, so that the cooling effect is ensured, and energy saving and noise reduction are realized.

[0218] Optionally, the control device determines the target working speed corresponding to the heat source according to the heat source size, comprising: in the case that the heat source size is greater than or equal to a first preset size, the control device outputs a first speed instruction to make the circulating fan run at a high speed; 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 speed instruction to make the circulating fan run at a medium speed; or in the case that the heat source size is less than the second preset size, the control device outputs a third speed instruction to make the circulating fan run at a low speed.

[0219] In this way, the working speed of the circulating fan can be determined and adjusted according to the heat source size in the rapid cooling area, so that the cooling intensity can be matched as needed. For a large-size heat source, the system can automatically provide strong air supply at a high speed to ensure rapid cooling; for a small-size heat source, the circulating fan runs at a low speed, so that unnecessary energy waste and excessive cooling are avoided. This gradient intelligent control ensures that the cold output accurately corresponds to the heat load, and significantly improves the refrigeration efficiency and energy utilization rate.

[0220] Optionally, the heat source information in the rapid cooling area further comprises a plurality of heat source positions corresponding to a plurality of heat sources respectively; the control device controls the circulating fan to start running in a variable-direction air outlet mode, comprising: the control device determines a plurality of target working angles respectively facing the plurality of heat sources according to the plurality of heat source positions corresponding to the plurality of heat sources respectively; and the control device controls the circulating fan to start running and alternately deliver cold air according to the plurality of target working angles.

[0221] In this way, for the case that a plurality of heat sources exist in the rapid cooling area at the same time, the circulating fan can be controlled by determining a plurality of target working angles and alternately delivering cold air, so that each heat source can be cooled in time, the cooling blind area is avoided, and the use experience in the multi-item storage scene is improved.

[0222] Optionally, the heat source information in the rapid cooling area further comprises heat source sizes of the plurality of heat sources; the control device controls the circulating fan to start running and alternately deliver cold air according to the plurality of target working angles, comprising: the control device determines a plurality of target working time lengths and / or target working rotating speeds corresponding to the plurality of heat sources respectively according to the heat source sizes of the plurality of heat sources; and the control device controls the circulating fan to start running 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.

[0223] In this way, the embodiments of the present disclosure further determine the target working time lengths and / or the target working rotating speeds corresponding to the plurality of heat sources according to the sizes of the plurality of heat sources, realize personalized and refined cooling of the plurality of heat sources, ensure that the distribution of cold energy resources matches the actual heat load of each heat source, and significantly improve the rapid cooling uniformity and energy efficiency.

[0224] Optionally, the control device determines a plurality of target working time lengths and / or target working rotating speeds corresponding to the plurality of heat sources respectively according to the heat source sizes of the plurality of heat sources, comprising: 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 length; 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 length; 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 length. The first air supply time length is greater than the second air supply time length, and the second air supply time length is greater than the third air supply time length.

[0225] In this way, the embodiments of the present disclosure can determine and adjust the target working time lengths and / or the target working rotating speeds corresponding to each heat source according to the heat source sizes of the plurality of heat sources, to realize personalized and accurate matching of cooling control of the plurality of 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 the heat source, for example, provide stronger air supply volume and / or longer air supply time for large-size heat sources, and accordingly reduce the air supply volume and / or the air supply time for small-size heat sources. This ensures that cold energy resources can be accurately and fairly distributed to each target, fundamentally solves the problem of low efficiency of cold energy distribution in the multi-heat-source scenario, and significantly improves the overall refrigeration efficiency and energy utilization rate.

[0226] Optionally, the circulating fans are multiple, and each is configured to deliver cold air to a sub-region inside the quick cooling region; the control device is configured to control the circulating fans to start operating according to the heat source information in the quick cooling region, so as to guide the cold air to cool the heat source in the quick cooling region, including: the control device is configured to determine a target circulating fan corresponding to the heat source according to the heat source information in the quick cooling region; and the control device is configured to control the target circulating fan to start operating, so as to guide the cold air to cool the heat source in the sub-region corresponding to the target circulating fan.

[0227] In this way, the embodiment of the disclosure can realize partitioned quick cooling through multiple circulating fans, and can independently provide cold air for different sub-regions, so as to realize real regionalized quick cooling and meet the complex storage layout requirements.

[0228] Optionally, the heat source information in the quick cooling region further includes a heat source position; the control device is configured to determine a target circulating fan corresponding to the heat source according to the heat source information in the quick cooling region, including: the control device is configured to determine a target sub-region in which the heat source position is located according to the heat source position; and the control device is configured to determine a circulating fan that delivers cold air to the target sub-region as the target circulating fan.

[0229] In this way, the embodiment of the disclosure can determine a sub-region in which the heat source is located according to the heat source position in the quick cooling region, and further determine a circulating fan that delivers cold air to the sub-region as the target circulating fan, so as to make the cold energy concentrated in the region around the heat source and realize directional cooling. The embodiment of the 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 circulating fans can still be relied on to maintain uniform and rapid cold energy coverage, and the problems of dispersed cold energy, slow temperature rollback and low energy efficiency in the conventional overall air supply mode can be significantly improved.

[0230] Optionally, in combination with Figure 12 as shown, the control device is further configured to execute the following control method, including:

[0231] S401, in the case of powering on the refrigerator, the control device acquires a predicted time point at which the user stores the heat source and a current time point.

[0232] 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 region.

[0233] S403, in the case that the temperature in the quick cooling region satisfies a pre-cooling temperature condition, the control device controls the circulating fan to pre-start before the predicted time point, so as to pre-cool the quick cooling region.

[0234] The control method for the refrigerator provided by the embodiment of the present disclosure can be used in the refrigerator in the powered-on operation state. The predicted time point at which the user stores the heat source is obtained, and the circulating fan is controlled to be pre-started before the time point when a specific condition is met. Thus, the embodiment of the present disclosure upgrades the traditional "passive response" rapid cooling mode to the "active prediction" pre-cooling mode. Through the analysis and prediction of the user behavior habit, the system can pre-cool the rapid cooling area before the user stores the heat source. This fundamentally eliminates the start lag caused by passive response, ensures sufficient cold storage when the heat source is stored, and greatly improves the rapid cooling efficiency and greatly optimizes the user experience.

[0235] Optionally, the control device obtains the predicted time point at which the user stores 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 at which the user stores the heat source on the current day according to the storage time prediction model.

[0236] In this way, the embodiment of the present disclosure can use the historical time information of the user storing the heat source to construct a storage time prediction model, and then analyze the predicted time point at which the user is likely to store the heat source next. Based on this, the embodiment of the present disclosure can provide a key self-learning capability 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.

[0237] 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.

[0238] In this way, the embodiment of the present disclosure can ensure that the pre-cooling function starts within the 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 the perfect balance of energy efficiency and effect.

[0239] 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 starts within the optimal time window, thereby realizing the balance of energy efficiency and effect. The pre-cooling start duration can also be adjusted according to the actual needs of the user, and can also be set to other arbitrary reasonable values.

[0240] Optionally, the pre-cooling temperature condition includes that the temperature in the rapid cooling area is greater than or equal to a pre-cooling start temperature; and / or, a difference between the temperature in the rapid cooling area and the temperature in the refrigeration compartment is greater than or equal to a pre-cooling start temperature difference.

[0241] In this way, the embodiment of the present disclosure provides specific precooling temperature condition judgment basis for the precooling function, ensures that the circulating fan is started only when precooling is needed (for example, the temperature of the rapid cooling area is too high or the temperature difference with the main refrigeration compartment is large), and further avoids unnecessary energy consumption.

[0242] Optionally, the precooling start temperature can be set in combination with the in-chamber refrigeration temperature. For example, the precooling start temperature can be set to 10°C, so as to ensure that the circulating fan is pre-started only when precooling is needed, and unnecessary energy consumption is avoided. The precooling start temperature can also be adjusted according to actual user needs, and can also be set to other arbitrary reasonable values.

[0243] Optionally, the precooling start temperature difference can be set in combination with the in-chamber refrigeration temperature. For example, the precooling start temperature difference can be set to 2°C, so as to ensure that the circulating fan is pre-started only when precooling is needed, and unnecessary energy consumption is avoided. The precooling start temperature difference can also be adjusted according to actual user needs, and can also be set to other arbitrary reasonable values.

[0244] Optionally, the control device controls the circulating fan to be pre-started 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 precooling parameters of the circulating fan according to the target heat source information; and the control device controls the circulating fan to be pre-started according to the target precooling parameters before the predicted time point.

[0245] In this way, the embodiment of the present disclosure can increase the prediction of the target heat source information, and determine the circulating fan parameters adapted to the target heat source information, so that the precooling function is not only to pre-ventilation, but also to prepare the most suitable precooling strategy according to the prediction of the future heat source (for example, type, size, position), so as to realize a more intelligent and personalized precooling experience.

[0246] 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.

[0247] In this way, the embodiment 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 embodiment 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, humidity and other information of the heat source before precooling start, the system can adjust the precooling parameters such as pre-set air volume and air direction according to the characteristics of the heat source, so as to realize more personalized and accurate precooling operation. This ensures that the refrigerator is ready for the most suitable refrigeration condition when the heat source is put in, and significantly improves the precooling efficiency and energy efficiency ratio.

[0248] Optionally, the target heat source information comprises a target heat source type; and the control device determines the target pre-cooling parameter of the circulating fan according to the target heat source information, comprising: in a case where the target heat source type is a hot pot, the target pre-cooling parameter of the circulating fan comprises a first pre-cooling time length and / or a first pre-cooling rotating speed; or in a case where the target heat source type is a beverage, the target pre-cooling parameter of the circulating fan comprises a second pre-cooling time length and / or a second pre-cooling rotating speed. The first pre-cooling time length is greater than the second pre-cooling time length, and the first pre-cooling rotating speed is greater than the second pre-cooling rotating speed.

[0249] In this way, the embodiments of the present disclosure can dynamically determine the target pre-cooling time length and / or the target pre-cooling rotating speed of the circulating 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 circulating fan in advance and pre-cool at a higher rotating speed or for a longer time to reserve sufficient cold energy. When it is predicted that the user will store a relatively small-heat-load object such as a beverage, the circulating fan can be pre-cooled at a lower rotating speed or for a shorter time. 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.

[0250] Optionally, after the control device determines the target pre-cooling parameter of the circulating fan according to the target heat source information, the control device further corrects the target pre-cooling parameter of the circulating fan according to the storage information of the refrigeration compartment.

[0251] In this way, after the target pre-cooling parameter of the circulating fan is determined 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 account, 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 the new heat source and be coordinated with the current running state of the refrigerator, thereby improving the reliability and energy saving of the control.

[0252] Optionally, the control device corrects the target pre-cooling parameter of the circulating fan according to the storage information of the refrigeration compartment, comprising: 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 circulating 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 circulating 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 circulating fan. The first preset proportion is greater than the second preset proportion.

[0253] In this way, the present embodiment can divide the storage proportion of the refrigeration compartment into different intervals, and correct the target precooling parameter of the circulating fan according to the intervals, so as to realize dynamic self-adaptation of the precooling intensity. When the storage proportion of the refrigeration compartment is high, the present embodiment can increase the target precooling parameter to compensate for the high heat load and ensure the rapid cooling effect; when the storage proportion is low, the present embodiment can reduce the target precooling parameter to avoid unnecessary energy consumption. In this way, the precooling strategy is more accurate, and the effective balance between energy efficiency and refrigeration effect is achieved.

[0254] Optionally, the control method further comprises: in the case that the temperature in the rapid cooling area does not satisfy the precooling temperature condition, controlling the device to control the circulating 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 area; and controlling the device to control the running state of the circulating fan according to the temperature in the rapid cooling area.
