[0002] Refrigerators are common household appliances that store items at low temperatures. Based on their cooling method, refrigerators are categorized as direct-cooling and indirect-cooling. Indirect-cooling refrigerators, also known as air-cooling refrigerators, utilize cold air to cool the storage compartment. These refrigerators typically have a separate refrigeration chamber within the cabinet, equipped with a heat exchanger and fan. The fan delivers the cold air from the chamber to the storage compartment, cooling the contents.

[0003] For indirect cooling refrigerators, since cold air is used to cool the storage compartment, there is a problem of concentrated cold air blowing directly at a certain place, which can easily lead to a large gap in the cooling effect between the storage items in the directly blown area and the storage items in other areas. No matter where the storage items are placed, it may have an adverse effect on the storage effect of the storage items. Utility Model Content

In this way, whether the airflow is directly sent into the storage room or the cold energy is transferred to the storage room by heat conduction, the cold energy can be evenly cooled in the storage room, thereby improving the uniformity of the cooling effect in the storage room and thus improving the preservation effect of the stored items in the storage room. In the conduction cooling method, it is also possible to prevent the cold air from blowing directly onto the stored items, further improving the preservation effect of the stored items.

[0059] Those skilled in the art should understand that the embodiments described below are only a portion of the embodiments of the present invention, rather than all of the embodiments of the present invention. These embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0060] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0061] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0062] like Figure 1 As shown, in one embodiment, the refrigerator 10 includes a housing 100 and a fresh-keeping container 200 according to any of the following embodiments. A storage compartment 101 is formed in the housing 100. The fresh-keeping container 200 is disposed in the storage compartment 101.

[0063] It should be noted that refrigerators typically have multiple storage compartments for different functions, such as a refrigeration compartment, a freezer compartment, a variable temperature compartment, and so on. The specific number and functions of the storage compartments can be configured based on pre-defined requirements. Fresh-keeping containers can be placed in any storage compartment. Figure 1 The refrigerator shown is only an example, and those skilled in the art can configure the specific number, function and layout of the storage compartments according to needs.

[0064] Furthermore, the refrigerator of this embodiment is an air-cooled refrigerator. A refrigeration space and an air duct system are provided within the refrigerator. The refrigeration space is equipped with a fan and a heat exchanger (evaporator). The fan delivers cold air, heated by the heat exchanger, through the refrigerator's air supply port to the storage compartment. The air is then returned to the refrigeration space through the refrigerator's air return port, achieving circulating air cooling. Since the refrigerator's cabinet, door, and refrigeration system are well known and readily implemented by those skilled in the art, the following description of the cabinet, door, and refrigeration system will be omitted to avoid obscuring or obscuring the key points of the present invention.

[0065] like Figures 2 to 6 As shown, in one embodiment, the fresh-keeping container 200 includes a barrel body 210 , a drawer 220 , an air guide assembly 230 , a side insulation layer 240 , a rear insulation layer 250 and a magnetic field assembly 260 .

[0066] like Figure 2 and Figure 3 As shown, the barrel body 210 is formed with a storage compartment 201 having a front opening. A drawer 220 is retractably disposed in the storage compartment 201, and the drawer 220 is used to store stored items. In other words, the drawer 220 can be pulled out of the storage compartment 201 or retracted into the storage compartment 201 through the front opening of the storage compartment 201. When the drawer 220 is retracted into the storage compartment 201, the front panel of the drawer 220 covers and seals the front opening of the barrel body 210.

[0067] like Figures 2 to 4 As shown, the barrel 210 is formed with two compartments distributed on the left and right and open at the front end, one of which is a storage compartment 201. Specifically, the left compartment is the storage compartment 201. The right compartment is connected to the storage compartment of the refrigerator to achieve the same cooling effect as the other areas of the storage compartment 101. The storage compartment 201 is cooled separately and insulated from the outside. Alternatively, the right compartment can also adopt the same configuration as the storage compartment 201.

[0068] Reference Figures 2 to 4 As shown, specifically, the fresh-keeping container 200 is formed with a cold air circuit for cooling the storage compartment 201. The cold air circuit is connected to the air supply port and the return air port of the refrigerator body, so that the cold air generated in the refrigeration space of the refrigerator can enter the cold air circuit and return to the refrigeration space after flowing through the cold air circuit, completing the circulation refrigeration of the storage compartment 201.

[0069] like Figures 2 to 5 As shown, the cold air circuit for cooling the storage compartment 201 surrounds the interior space of the drawer 220, including a cooling duct 202 located on the top side of the interior space of the drawer 220, a front section 203 located on the front side of the interior space of the drawer 220, and a bottom section 204 located at the bottom of the interior space of the drawer 220.

[0070] like Figures 2 to 7 As shown, the air guide assembly 230 includes a duct member 231 and multiple diverter posts 232. Duct member 231 forms a cooling duct 202, which connects to the refrigerator's cooling source. Cooling duct 202 is isolated from and abuts against storage compartment 201, allowing it to transfer cooling energy to storage compartment 201. Multiple diverter posts 232 are disposed within cooling duct 202 to disperse the airflow across its width.

[0071] like Figures 2 to 7 Specifically, as shown, the duct member 231 is disposed on the outside of the top sidewall of the barrel body 210 and includes a top insulation layer 2311 and a magnetic field generating module 2312. The top insulation layer 2311 is disposed on the side of the magnetic field generating module 2312 facing away from the barrel body 210. The top insulation layer 2311 and the magnetic field generating module 2312 together form the cooling duct 202. The top insulation layer 2311 provides thermal insulation, while the magnetic field generating module 2312 generates a magnetic field that acts on the storage compartment 201.

[0072] Reference Figures 2 to 7Specifically, the top insulation layer 2311 and the magnetic field generating module 2312 are both plate-shaped. A depression extending from the rear end to the front end is formed on the side of the top insulation layer 2311 facing the magnetic field generating module 2312. Once the top insulation layer 2311 and the magnetic field generating module 2312 are assembled, the depression of the top insulation layer 2311 and the top surface of the magnetic field generating module 2312 form a cooling duct 202 extending from the rear end to the front end of the barrel 210. The cooling duct 202 is isolated from and abuts against the storage compartment 201 via the magnetic field generating module 2312 and the top sidewall of the barrel 210.

[0073] Continue to refer to Figures 2 to 7 As shown, multiple diverter posts 232 are arranged in multiple rows spaced apart along the direction of airflow within the cooling duct 202, with each row comprising at least one diverter post 232. Specifically, airflow flows from back to front along the barrel 210 within the cooling duct 202, i.e., the multiple diverter posts 232 are arranged in multiple rows along the barrel 210 from back to front. The diverter posts 232 are formed by protruding from the side of the top insulation layer 2311 facing the magnetic field generating module 2312, i.e., they are integrally formed with the top insulation layer 2311.

[0074] It should be noted that the diverter column can be formed together with the air duct component, or can be formed separately and fixed in the refrigeration air duct.

[0075] Continue to refer to Figures 2 to 7 As shown, the width of the cooling duct 202 is the dimension perpendicular to the direction of airflow. As airflow flows from back to front along the barrel 210 within the cooling duct 202, the width of the cooling duct 202 is the dimension along the left-right direction of the barrel 210. As the airflow flows from back to front within the cooling duct 202 along the barrel 210, it encounters the diverter posts 232 and is dispersed to the left and right by the diverter posts 232, further dispersing the airflow in the left-right direction. As the airflow continues to flow forward within the cooling duct 202, it is further dispersed by the diverter posts 232, resulting in a more uniform distribution of the airflow within the cooling duct 202. The cooling energy carried by the airflow can be transferred to the storage compartment 201 to a certain extent via the magnetic field generating module 2312 and the top sidewall of the barrel 210. Because the airflow is evenly distributed within the cooling duct 202, the cooling effect on the storage compartment 201 is more uniform.

[0076] In this embodiment, a cooling duct 202 is formed using a duct member 231 and provided with multiple diverter columns 232 within the cooling duct 202. As air flows through the cooling duct 202, it encounters the diverter columns 232, which disperse the air to the sides. Furthermore, because the diverter columns 232 are relatively small, they do not occupy as much space within the cooling duct 202 as guide ribs extending along the airflow direction. This allows the airflow to be evenly distributed within the cooling duct 202. This ensures that the airflow is evenly distributed within the cooling duct 202, whether the airflow is delivered directly into the storage compartment or by heat conduction. This improves the uniformity of the cooling effect within the storage compartment, thereby enhancing the freshness of stored items. Furthermore, the conduction method prevents the cold air from directly hitting the stored items, further enhancing the freshness of the stored items.

[0077] Furthermore, by utilizing the barrel 210 to form the storage compartment 201, and utilizing the top insulation layer 2311 and the magnetic field generating module 2312 to form the air guide assembly 230, the magnetic field generating module 2312 can generate a magnetic field acting on the storage compartment 201 while uniformly cooling the storage compartment 201, thereby achieving magnetic field preservation for stored items. This magnetic field not only helps maintain a supercooled state at a lower temperature, but also has a certain sterilizing effect, thereby helping to improve the freshness of stored food. Furthermore, the top insulation layer 2311 can provide a thermal insulation effect, preventing the leakage of airflow cooling energy and improving cooling efficiency.

[0078] Furthermore, because the airflow is dispersed by the diverter column 232, it can evenly cool the storage compartment 201 while also making the airflow softer. This prevents the temperature of the storage compartment 201 from dropping too quickly, allowing the temperature required for magnetic field preservation to be reached more smoothly, preventing the temperature from exceeding the required range too quickly, and thus further facilitating magnetic field preservation. Furthermore, the conduction of cooling energy can further prevent the temperature of the storage compartment 201 from dropping too quickly, further enhancing the magnetic field preservation effect.

[0079] In addition, by arranging multiple diverter columns 232 to be distributed in multiple rows along the flow direction of the air flow in the cooling duct 202, each row is provided with at least one diverter column 232. When the air flow flows in the cooling duct 202, as the air flow continues to flow forward in the cooling duct 202, the air flow is also continuously dispersed by each row of diverter columns 232, thereby improving the dispersion effect of the air flow.

[0080] It should be noted that, in some other embodiments, the air guide assembly can also be composed of other structures, such as a plastic shell. In addition, the air guide assembly can be composed of a top insulation layer and the side wall of the barrel.

[0081] In addition, it should be noted that in some other embodiments, the cooling air duct can also directly supply air to the storage compartment. For example, through holes are provided in the magnetic field generating module and the top side wall of the barrel body, and air is supplied to the storage compartment through the through holes.

[0082] like Figures 2 to 8 As shown, the magnetic field generating module 2312 includes a shim plate 2313 and a plurality of permanent magnets 2314, which are arranged on the side of the shim plate 2313 facing the barrel 210. In other words, the shim plate 2313 and the top insulation layer 2311 form a cooling air duct 202.

[0083] Those skilled in the art will appreciate that by providing the shimming plate 2313 and the plurality of permanent magnets 2314, on the one hand, the plurality of permanent magnets 2314 can be utilized to generate a magnetic field within the storage compartment 201. This means that the same permanent magnets 2314 generate a magnetic field at different locations within the storage compartment 201, thereby improving the uniformity of the magnetic field within the storage compartment 201 and enhancing the food preservation effect. On the other hand, the shimming plate 2313 can guide the magnetic field generated by the permanent magnets 2314, thereby further improving the uniformity of the magnetic field generated by the permanent magnets 2314 within the storage compartment 201.

[0084] It should be noted that, in some other embodiments, the magnetic field generating module may also be a whole large permanent magnet sheet, and the permanent magnet sheet and the top insulation layer constitute a cooling air duct.

[0085] Reference Figures 2 to 6 As shown, the fresh-keeping container 200 is also formed with an air inlet 205 that communicates with the cooling duct 202. The air inlet 205 interfaces with the air supply port of the refrigeration space of the refrigerator body, allowing the cold air generated in the refrigeration space to enter the cooling duct 202 through the air inlet 205. In other words, the cooling duct 202 is connected to the refrigerator's cooling source via the air inlet 205.

[0086] Reference Figures 2 to 5 As shown, the front section 203 is formed inside the front panel of the drawer 220. Specifically, the front panel of the drawer 220 has a relatively thick and hollow portion, which is used to form the front section 203. In addition, the top of the front section 203 has an opening, and the front end of the cooling duct 202 has an opening. The cold air in the cooling duct 202 flows through the front opening to the top opening of the front section 203 and then enters the front section 203.

[0087] Reference Figures 2 to 5 As shown, the bottom section 204 is formed between the bottom wall of the drawer 220 in the closed state and the inner bottom wall of the barrel 210. The bottom of the front section 203 has an opening, and the cold air flow in the front section 203 flows into the bottom section 204 through the bottom opening, that is, into the storage compartment 201.

[0088] Reference Figures 2 to 5 As shown, in addition, the rear side wall of the barrel body 210 is provided with an air hole 206 (see Figure 12 As shown in FIG2 , the cold airflow entering the bottom section 204 flows from front to back, flows to the rear of the storage compartment 201, and then flows out of the storage compartment 201 through the air hole 206. An air guide duct that connects to the air hole 206 is formed between the rear insulation layer 250 and the rear side wall of the barrel body 210. In addition, the fresh-keeping container 200 is formed with an air outlet 207 that communicates with the air guide duct. The air outlet 207 connects to the return air outlet of the refrigeration space of the refrigerator body. The cold airflow flowing out of the air hole 206 flows through the air guide duct to the air outlet 207, and then returns to the refrigeration space of the refrigerator, completing the cooling of the storage compartment 201, mainly the space inside the drawer 220.

[0089] Those skilled in the art will appreciate that the above-described structural configuration enables multi-directional cooling of the interior of drawer 220, improving the uniformity and efficiency of the cooling effect. Furthermore, this prevents cold air from directly blowing into the interior of drawer 220, thereby preventing the temperature of stored items within drawer 220 from dropping too quickly. This allows the items to gradually reach the required temperature for magnetic field preservation, thereby better achieving magnetic field preservation.

[0090] It should be noted that in some other embodiments, only a cooling duct may be provided, with the cold air flowing directly out of the fresh-keeping container from the front of the cooling duct and into the storage compartment of the refrigerator. Alternatively, through holes may be provided in the magnetic field generating module and the top sidewall of the barrel body, through which air is supplied to the storage compartment, and then returned to the refrigerated space of the refrigerator body through the air holes and outlet.

[0091] Reference Figures 2 to 5 As shown, regarding the thermal insulation structure of storage compartment 201, first, an insulation layer is provided between storage compartment 201 and the other compartment formed by barrel body 210 to provide thermal insulation between storage compartment 201 and the other compartment. In other words, storage compartment 201 and the other compartment share a thermally insulating side wall (constituting the right side wall of storage compartment 201). In addition, a top insulation layer 2311 is provided on the outside of the top wall of storage compartment 201, a side insulation layer 240 is provided on the outside of the left side wall of storage compartment 201, and a rear insulation layer 250 is provided on the outside of the rear side wall of storage compartment 201, thereby providing thermal insulation between storage compartment 201 and the storage compartment.

[0092] It should be noted that the outer side of the storage compartment bottom sidewall is also provided with a bottom insulation layer. However, in other embodiments, because the bottom sidewall of the barrel can better fit the box wall, the bottom insulation layer may not be provided.

[0093] In addition, it should be noted that, in some other embodiments, the fresh-keeping container may have only one storage compartment, and both side walls may be provided with insulation layers, or one side wall may be in contact with the box wall, so that only one side wall is provided with an insulation layer.

[0094] like Figures 2 to 9 As shown, the magnetic field assembly 260 and the magnetic field generating module 2312 are respectively disposed on opposite sides of the storage compartment 201, that is, the magnetic field assembly 260 is disposed on the bottom side of the storage compartment 201. The specific structure of the magnetic field assembly 260 can be configured with reference to the magnetic field generating module 2312. In addition, the fresh-keeping container 200 also includes two magnetic conductive connectors 270. The two magnetic conductive connectors 270 are respectively disposed on opposite sides (left and right) of the storage compartment 201, and each magnetic conductive connector 270 is used to connect the magnetic field assembly 260 and the magnetic field generating module 2312.

[0095] It will be understood by those skilled in the art that by providing the magnetic conductive connector 270, the magnetic field generated by the magnetic field assembly 260 and the magnetic field generating module 2312 can be guided and gathered, which helps to concentrate the magnetic field generated by the magnetic field assembly 260 and the magnetic field generating module 2312 within the storage compartment 201 and distribute it more evenly within the storage compartment 201.

[0096] It should be noted that, in some other embodiments, the magnetic conductive connector may not be provided. In addition, in some other embodiments, the magnetic field assembly may not be provided.

[0097] like Figures 10 to 13 As shown, in some embodiments, the barrel body 210 includes an upper shell 2101 and a lower shell 2102, which are spliced ​​longitudinally to form the outer sidewalls of the barrel body 210. Specifically, the upper shell 2101 forms the top wall of the barrel body 210, and the lower shell 2102 forms the bottom wall of the barrel body 210. In addition, the upper shell 2101 and the lower shell 2102 together form the left sidewall, right sidewall, and rear sidewall of the barrel body 210.

[0098] Those skilled in the art will appreciate that by configuring the barrel body 210 as a structure composed of an upper shell 2101 and a lower shell 2102, the components inside the barrel body 210 can be installed first during the production process, and then the upper shell 2101 and the lower shell 2102 can be spliced ​​together, thereby facilitating the production and assembly of the barrel body 210. In addition, during subsequent maintenance, the upper shell 2101 and the lower shell 2102 can be disassembled to perform maintenance on the interior of the barrel body 210, thereby facilitating maintenance of the barrel body 210.

[0099] It should be noted that, in some other embodiments, the barrel body may also be an integrally formed structure, that is, the entire outer side wall of the barrel body is an integrally formed structure.

[0100] Continue to refer to Figures 10 to 13 As shown, the upper shell 2101 and the lower shell 2102 are connected by a snap-fit ​​structure. Specifically, the upper shell 2101 is provided with a snap 2103, and the lower shell 2102 is provided with a snap protrusion 2104. The snap 2103 is snapped into the snap protrusion 2104 to achieve the connection between the upper shell 2101 and the lower shell 2102.

[0101] Reference Figures 2 to 4 In some embodiments, the fresh-keeping container 200 includes a top cover 280, which is placed on top of the top insulation layer 2311. The side walls of the top cover 280 partially cover the side insulation layers 240, and the rear wall of the top cover 280 partially covers the rear insulation layer 250. The top cover 280 is fixed to the side insulation layers 240, and the top cover 280 is fixed to the rear insulation layer 250, for example, by screws, thereby reinforcing the connection between the top insulation layer 2311, the side insulation layers 240, and the rear insulation layer 250.

[0102] Reference Figure 14 As shown, in one embodiment, the diverter column 232 is an elliptical column, the long diameter end of the elliptical column faces the air inlet of the cooling air duct, and the side of the elliptical column is closer to the streamline, thereby dispersing the airflow while making the airflow flow better and smoother.

[0103] Continue to refer to Figure 14 As shown, along the flow direction of the airflow in the cooling duct, multiple diverter posts 232 are arranged in multiple rows with intervals, and each row is provided with at least one diverter post 232. In each row of diverter posts 232, the end of the diverter post 232 that is offset from the center of the distribution direction of all diverter posts 232 and is close to the air inlet end of the cooling duct is inclined toward the center of the distribution direction.

[0104] like Figure 14 Specifically, the upper end of the figure is the air inlet end of the cooling duct, and each row of diverter posts 232 is distributed in a left-right direction. As shown in the figure, the first row has two diverter posts 232, one located to the left and one to the right of the center of the distribution direction. The upper end of the left diverter post 232 is tilted to the right, while the upper end of the right diverter post 232 is tilted to the left. This structural arrangement enables the diverter posts 232 to better guide and disperse the airflow toward the edge of the cooling duct, helping to improve the uniformity of airflow distribution in the cooling duct.

[0105] Reference Figure 14 As shown, the number of rows of the diverter columns 232 is set according to the approximate value of the result of the row number calculation formula. The approximate value of the result of the row number calculation formula is the integer value after rounding off the calculation result.

[0106] The formula for calculating the number of rows is:

[0107] N=30×H / √S;

[0108] Where N is the number of diverter columns, H is the length of the cooling duct in the direction of airflow, in meters, and S is the air velocity within the cooling duct, in meters per second. In other words, the number of diverter columns is set by multiplying 30 by the length of the cooling duct in the direction of airflow, then dividing by the square root of the air velocity within the cooling duct.

[0109] like Figure 14 As shown in the mid-plane, the upper end is the air inlet end of the cooling air duct, the lower end is the air outlet end of the cooling air duct, the air flow direction is from top to bottom, and H is the length of the cooling air duct in the vertical direction.

[0110] For example, when H=0.35 m and S=3 m / s, then N=6, that is, 6 rows of diverter columns are provided.

[0111] In the solution of this embodiment, the number of rows of diverter columns is set according to the length of the cooling duct in the direction of air flow and the flow rate of the air flow in the cooling duct, so that the number of rows of diverter columns is set more reasonably, which helps to avoid excessive obstruction of the airflow in the direction of air flow due to a large number of rows of diverter columns on the basis of ensuring a good diversion effect on the airflow, thereby ensuring a better diversion effect and ensuring the smoothness of the airflow.

[0112] Reference Figure 14 As shown, the distance between the axis connecting all the diverter columns 232 in each row and the air inlet end of the cooling duct is set according to the approximate value calculated by the row spacing calculation formula. The approximate value calculated by the row spacing calculation formula is the value rounded to two decimal places.

[0113] The formula for calculating line spacing is:

[0114] h n =n×H / (N+1)

[0115] Among them, h n is the distance between the axis connecting all the diverter posts in each row and the cooling duct inlet; n is the row number of each row of diverter posts from the cooling duct inlet; N is the number of diverter posts in each row; and H is the length of the cooling duct in the direction of airflow, in meters. In other words, the distance between the axis connecting all the diverter posts in each row and the cooling duct inlet is calculated by multiplying the row number of each row of diverter posts from the cooling duct inlet by the length of the cooling duct in the direction of airflow, divided by the number of diverter posts in each row plus one.

[0116] like Figure 14As shown in the figure, the distance h1 between the axis connection line of all the diverter columns in the first row starting from the air inlet end of the cooling duct and the air inlet end of the cooling duct and the distance h2 between the axis connection line of all the diverter columns in the second row starting from the air inlet end of the cooling duct and the air inlet end of the cooling duct are shown.

[0117] For example, when H = 0.35m and N = 6, that is, when 6 rows of diverter posts are provided, the distance h1 between the axis connecting all diverter posts and the air inlet of the cooling duct is 0.05m for the first row of diverter posts, n = 1, and the distance h6 between the axis connecting all diverter posts and the air inlet of the cooling duct is 0.30m for the sixth row of diverter posts, n = 6.

[0118] By setting the distance between the axis connecting all the diverter columns 232 in each row and the air inlet end of the cooling air duct according to the approximate value calculated by the row spacing calculation formula, it helps to ensure that each row of diverter columns 232 has an appropriate row spacing.

[0119] Reference Figure 14 As shown, the number of diversion columns 232 in each row is set according to the approximate value of the column number calculation formula, which is an integer value after rounding off the calculation result.

[0120] The formula for calculating the number of bars is:

[0121] M=35×d / √S

[0122] Where M is the number of manifolds in each row; d is the width of the cooling duct at each row of manifolds, in meters; and S is the airflow velocity within the cooling duct, in meters per second. The width of the cooling duct at each manifold is the dimension of the cooling duct along the line connecting the axes of the manifolds. In other words, the number of manifolds in each row is calculated by multiplying 35 by the width of the cooling duct at each row of manifolds, then dividing by the calculated airflow velocity within the cooling duct under the square root of 35.

[0123] like Figure 14 As shown in FIG, the width d of the cooling air duct at the location of the third row of diverter columns from the top to the bottom is indicated.

[0124] For example, when S = 3 m / s, the width of the cooling duct where a row of diverter posts is located is d = 0.1 m, then M = 2, i.e., two diverter posts are provided. If the width of the cooling duct where another row of diverter posts is located is d = 0.2 m, then M = 4, i.e., four diverter posts are provided.

[0125] Reference Figure 14As shown, the distances between the two end diverter columns 232 in each row of diverter columns 232 and the side of the cooling duct are set according to the approximate value calculated by the side column distance calculation formula. The approximate value calculated by the side column distance calculation formula is the value rounded to two or three decimal places.

[0126] The calculation formula for side column distance is:

[0127] A=d / 2M

[0128] Where A is the distance between the two diverter posts at the end of each row and the side of the cooling duct, in meters; d is the width of the cooling duct at the location of each diverter post, in meters; and M is the number of diverter posts in each row. In other words, the distance between the two diverter posts at the end of each row and the side of the cooling duct is calculated by dividing the width of the cooling duct at the location of each diverter post by twice the number of diverter posts in each row.

[0129] like Figure 14 As shown in FIG, the distance A between the rightmost diverter column in the last row from the top to the bottom and the side of the cooling duct is indicated.

[0130] For example, when d=0.1 m and M=2, A is equal to 0.025 m. When d=0.13 m and M=3, A is equal to 0.02 m.

[0131] Reference Figure 14 As shown, the distance between two adjacent diverter columns 232 in each row of diverter columns 232 is set according to the approximate value of the column spacing calculation formula. The approximate value of the column spacing calculation formula is the value rounded to two or three decimal places.

[0132] The formula for calculating column spacing is:

[0133] B=d / M

[0134] Where B is the distance between two adjacent diverter posts in each row, measured in meters; d is the width of the cooling duct at the location of each row of diverter posts, measured in meters; and M is the number of diverter posts in each row. In other words, the distance between two adjacent diverter posts in each row is calculated by dividing the width of the cooling duct at the location of each row of diverter posts by the number of diverter posts in each row.

[0135] like Figure 14 As shown in FIG, the distance B between two adjacent diverter columns in the last row of diverter columns from the top to the bottom is shown.

[0136] For example, when d=0.1 m and M=2, B is equal to 0.05 m. When d=0.13 m and M=3, B is equal to 0.04 m.

[0137] Through the above arrangement, the spacing between each row of diverter columns and the spacing between the diverter columns at both ends and the side of the cooling air duct are more appropriate, which has a better airflow dispersion effect.

[0138] Reference Figure 14 As shown, when the diverter column 232 is an elliptical column, the minor diameter of the elliptical column is set according to the approximate value calculated by the minor diameter calculation formula; the major diameter of the elliptical column is set according to the approximate value calculated by the major diameter calculation formula. The approximate values ​​of the minor diameter calculation formula and the approximate values ​​of the major diameter calculation formula are calculated by rounding the results to two or three decimal places.

[0139] The formula for calculating the short diameter is:

[0140] R = √D / (80×√S);

[0141] The formula for calculating the long diameter is:

[0142] L = √D / (40×√S);

[0143] Wherein, R is the minor diameter of the elliptical cylinder, in meters; L is the major diameter of the elliptical cylinder, in meters; D is the maximum width of the cooling duct, in meters; S is the flow velocity of the air flow in the cooling duct, in meters per second.

[0144] That is, the short diameter of the elliptical cylinder is set by dividing the maximum width of the cooling duct under the square root of 80, and then dividing it by the flow velocity of the airflow in the cooling duct under the square root of 1. The long diameter of the elliptical cylinder is set by dividing the maximum width of the cooling duct under the square root of 40, and then dividing it by the flow velocity of the airflow in the cooling duct under the square root of 1.

[0145] like Figure 14 As shown in FIG, the maximum width D of the cooling air duct is indicated.

[0146] For example, when D=0.26 m and S=3 m / s, the minor diameter R of the elliptical cylinder is 0.004 m, and the major diameter L of the elliptical cylinder is 0.007 m.

[0147] Through the above arrangement, the size of the elliptical cylinder is more appropriate, and the air flow diversion effect is better.

[0148] It should be noted that in some other embodiments, the diverter column can also be a cylinder, and the diameter of the cylinder can be determined by referring to the calculation formula of the short diameter of an elliptical cylinder. In addition, the diverter column can also be a column of other shapes, as long as the side facing the air inlet end of the cooling duct is a convex surface to play a diverting role.

[0149] Although not shown in the figures, in some other embodiments, the refrigerator body is formed with a storage compartment, and an air guide assembly is disposed outside the storage compartment and communicates with the storage compartment, so that cold air from the refrigerator's cooling source is dispersed by the air guide assembly before entering the storage compartment. Alternatively, the air guide assembly is disposed inside the storage compartment and communicates with the storage compartment, so that cold air from the refrigerator's cooling source is dispersed by the air guide assembly before entering the storage compartment. Alternatively, the air guide assembly is disposed outside or inside the storage compartment, but neither is communicated with the storage compartment, and is isolated from and adjacent to the refrigerator's storage compartment to transfer cold air to the storage compartment.

[0150] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention.
