[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0041] The present application embodiment provides a refrigerator, for example, see Figure 1-Figure 3 , Figure 1 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of the present application. Figure 2 An exploded view of a part of the structure of a refrigerator provided in an embodiment of the present application, Figure 3 A perspective view of a partition assembly provided in an embodiment of the present application. The refrigerator 100 includes a refrigerating chamber 110 , a cooling air duct (not shown in the figure), a drawer assembly 120 and a partition assembly 130 .

[0042] The cooling air duct is spaced apart from the refrigerating chamber 110 to provide cooling airflow. The drawer assembly 120 is slidably connected to the refrigerating chamber 110 to slide into or out of the refrigerating chamber 110. The drawer assembly 120 forms a storage space 122 with a storage opening 121 facing upward.

[0043] The partition assembly 130 is installed in the refrigerator compartment 110 and is disposed above the drawer assembly 120. The partition assembly 130 is provided with an air inlet 131a connected to the cooling air duct, and is formed with a plurality of air ducts 132 connected to the air inlet 131a, each of which includes a first side wall 133 facing the storage opening 121, and each of which is provided with a plurality of through holes 134 connected to the storage opening 121, and each through hole 134 is used to discharge air to the storage space 122.

[0044] In actual application, the cold air in the cooling air duct enters the partition assembly 130 through the air inlet 131a and is divided into multiple air ducts 132. Each air duct 132 simultaneously discharges air to the storage space 122 through multiple through holes 134 on the first side wall 133 to adjust the temperature of the storage space 122.

[0045] The refrigerator 100 provided in the embodiment of the present application supplies air to the storage space 122 at the same time through the multiple air ducts 132 formed by the partition assembly 130, and each air duct 132 also supplies air to the storage space 122 through the microporous structure on the first side wall 133. This can greatly improve the uniformity of air supply to various areas of the storage space 122, avoid large temperature differences between various areas of the storage space 122, and is beneficial to improving the preservation effect of food in the storage space 122.

[0046] Optionally, each air duct 132 includes a plurality of sub-air ducts 1321 arranged along a first direction X. Each sub-air duct 1321 extends along a second direction Z. Two adjacent sub-air ducts 1321 are connected. Preferably, the first direction X is perpendicular to the second direction Y, the first direction X is the length direction of the refrigerator 100, and the second direction Z is the width direction of the refrigerator 100. Preferably, in the first direction X, each two adjacent sub-air ducts 1321 are connected through a connecting port 1322, and each two adjacent connecting ports 1322 are staggered in the second direction Y to form a tortuous and continuous ventilation path.

[0047] Optionally, in the first direction X, the two sub-air ducts 1321 located at both ends are connected to the air inlet 131a. Exemplarily, the number of air ducts 132 is two, namely the first air duct and the second air duct. The first air duct and the second air duct are arranged side by side in the first direction X, and the first air duct and the second air duct respectively include three sub-air ducts 1321. The partition assembly 130 includes a first side 130a, a second side 130b and a middle portion 130c located between the first side 130a and the second side 130b in the first direction X. The first air duct is close to the first side 130a, and the second air duct is close to the second side 130b. Among them, the sub-air duct 1321 in the first air duct close to the first side 130a and the sub-air duct 1321 in the second air duct close to the second side 130b are connected to the air inlet 131a. In actual application, the airflow in the first air duct gradually flows from the first side 130a to the middle part 130c, and at the same time, the airflow in the second air duct gradually flows from the second side 130b to the middle part 130c. By supplying air to the edge area of ​​the storage space 122 first and then to the middle area, the temperature of each area inside the storage space 122 can be made more uniform. In some embodiments, the side walls of the first air duct and the second air duct near the air inlet 131a are further provided with openings 1323 for air intake, thereby further improving the uniformity of air supply to each area of ​​the storage space 122.

[0048] For example, see Figure 4 , Figure 4 The exploded view of the partition assembly provided in the embodiment of the present application. The partition assembly 130 includes a partition body 135 , an air duct cover 136 , a plurality of air duct plates 137 and a heat insulating member 139 .

[0049] The partition body 135 is, for example, made of glass and is disposed above the drawer assembly 120. The air duct cover 136 is disposed between the partition body 135 and the drawer assembly 120. The air duct cover 136 is provided with the above-mentioned air inlet 131a and a plurality of through holes 134. The refrigerating chamber 110, for example, includes a refrigerating chamber 111 and a refrigerating duct seat 112, the refrigerating duct seat 112 being disposed inside the refrigerating chamber 111 and mounted on the back plate of the refrigerating chamber 111, thereby forming a refrigerating duct, which is connected to the cooling duct of the refrigerator. The refrigerating duct seat 112 is provided with a refrigerating air supply port 113 connected to the refrigerating duct. Optionally, the air duct cover 136 includes a first side plate 1361 close to the back plate of the refrigerating chamber 110 and a top plate 1362 facing the storage port 121. The air inlet 131a is provided on the first side plate 1361 and communicates with the refrigeration air supply port 113. A plurality of through holes 134 are provided on the top plate 1362. The air duct cover 136 is provided on the partition body 135 to form a wind passage space 138 communicating with the air inlet 131a and the plurality of through holes 134. A plurality of air duct plates 137 are provided in the wind passage space 138 and are surrounded by the air duct cover 136 and the partition body 135 to form a plurality of air ducts 132.

[0050] The heat insulating member 139 is, for example, a heat insulating sponge, and is disposed on the partition body 135 to form the inner surface of the wind passage space 138 and / or the air duct cover 136 to form the inner surface of the wind passage space 138. The heat insulating member 139 is used to prevent the cold air entering the partition assembly 130 from exchanging heat with the external air, so as to avoid affecting the accuracy of the temperature control of the drawer assembly 120 and the uniformity of the temperature of each area inside the storage space 122.

[0051] In some embodiments, the partition assembly 130 also includes a guide plate 1310, which is disposed at the curved section of the air duct 132 to guide the airflow inside the air duct 132 to prevent the airflow from forming a vortex in the curved section and affecting the smoothness of the airflow.

[0052] In some embodiments, see Figure 5 , Figure 5 The exploded view of the drawer assembly provided in the embodiment of the present application. The drawer assembly 120 includes a drawer body 123 and a drawer front cover 124 .

[0053] It can be understood that the partition assembly 130 is installed in the refrigerator compartment 110 and is surrounded by the inner wall of the refrigerator compartment 110 to form a storage space 115 having an opening 114. The drawer body 123 forms a storage space 122 having a storage opening 121. The drawer front cover 124 is installed at one end of the drawer body 123 for pulling out. The drawer body 123 is slidably connected to the refrigerator compartment 110 to slide into or out of the storage space 115, and the drawer front cover 124 is used to move with the drawer body 123 to open or close the opening 114.

[0054] See also Figure 6 , Figure 6 Schematic diagram of the structure of the magnetic field preservation assembly provided in the embodiment of the present application installed on the drawer body. The refrigerator 100 also includes a magnetic field preservation assembly 140. The magnetic field preservation assembly 140 is installed on the lower surface of the drawer body 123, and is used to apply a magnetic field to the storage space 122, thereby preserving food.

[0055] Each air duct 132 has an air outlet 131b at one end away from the air inlet 131a. Exemplarily, the air duct cover 136 also includes a second side plate 1363 near the drawer front cover 124. The plurality of air outlets 131b are, for example, all connected. The air outlet 131b is opened on the second side plate 1363. Figure 7 , Figure 7A partial cross-sectional view of a refrigerator provided in an embodiment of the present application. The drawer body 123 includes a front side plate 1231 for pulling out, and the drawer front cover 124 is covered on the front side plate 1231 and a heat dissipation channel 125 is formed between the two. One end of the heat dissipation channel 125 is connected to a plurality of air outlets 131b, and the other end is used to face the bottom of the drawer body 123. It can be understood that the magnetic field preservation component 140 is located below the drawer body 123, and the heat dissipation channel 125 dissipates heat from the magnetic field preservation component 140 by discharging air to the bottom of the drawer body 123.

[0056] During the actual air supply process from the partition assembly 130 to the drawer assembly 120, part of the cold air is evenly supplied to the storage space 122 through the multi-hole structure 134 on the air duct cover 136, and the other part flows to the end of the air duct 132 and flows into the heat dissipation channel 125 through the air outlet 131b, and finally flows out to the bottom of the drawer body 123 under the guidance of the heat dissipation channel 125, thereby realizing the heat dissipation of the magnetic field preservation assembly 140.

[0057] The refrigerator 100 provided in the embodiment of the present application supplies air to the storage space 122 at the same time through the multiple air ducts 132 formed by the partition assembly 130, and each air duct 132 also supplies air to the storage space 122 through the microporous structure on the first side wall 133, which can greatly improve the uniformity of air supply to each area of ​​the storage space 122, avoid a large temperature difference between each area of ​​the storage space 122, and help improve the preservation effect of food in the storage space 122. In addition, during the air supply process, part of the cold air flows through the partition assembly 130 and then flows to the bottom of the drawer body 123 through the heat dissipation channel 125 at the front end of the drawer assembly 120, thereby achieving heat dissipation of the magnetic field preservation assembly 140. It can be understood that since the end of the drawer assembly 120 for drawing is close to the door body of the refrigerator 100 and is directly exposed to the storage space inside the refrigerating chamber 110, it is easier to exchange heat with the outside of the drawer assembly 120, resulting in a decrease in the uniformity of the temperature of the storage space 122. Therefore, through the above-mentioned configuration, cold air continuously flows through the front end of the drawer assembly 120, which can prevent the temperature uniformity of the storage space 122 from being affected.

Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. At the same time, for technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
