Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0002] Refrigerators are an indispensable household appliance for modern families. Among them, air-cooled refrigerators are more popular among consumers due to their frost-free performance, multiple temperature zones, and large storage capacity.

[0003] In the prior art, air-cooled refrigerators include a refrigerator compartment and a freezer compartment, which can share a single refrigeration system. This refrigeration system includes an evaporator and a fan. The evaporator absorbs heat from the refrigerator, lowering the internal temperature. The fan promotes air circulation within the refrigerator.

[0004] However, existing refrigerators have the problem of odor transfer, which affects storage quality. Utility Model Content

[0005] The embodiment of the present application provides a refrigerator, which avoids the problem of refrigerator odor transfer, improves the food storage quality of the refrigerator, and improves the performance of the refrigerator.

[0006] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0007] The box body is used to construct the refrigeration compartment, which includes the cold storage compartment and the freezer compartment;

[0008] The door is connected to the cabinet to open and close the refrigeration compartment;

[0009] An air duct assembly is constructed to form an air duct; the air duct is respectively connected to the refrigeration compartment and the freezing compartment;

[0010] The refrigeration system is installed in the box and is used to provide cooling for the refrigeration compartment and the freezer compartment;

[0011] Shelves are located in the cold storage room; the shelf structure forms a cold air channel;

[0012] A support structure is formed on the cavity wall of the refrigerated compartment, and the support structure includes:

[0013] The first supporting rib supports the shelf inside the cold storage room;

[0014] The second supporting ribs support the shelf in the refrigerator compartment, and the second supporting ribs are spaced apart from the first supporting ribs along the height direction of the refrigerator;

[0015] A connecting vent is provided on the cavity wall of the refrigerating compartment, and the connecting vent is communicated with the air duct.

[0016] In which, the shelf is constructed to be selectively installed on the first supporting rib or the second supporting rib, and when the shelf is constructed to be installed on one of the first supporting rib and the second supporting rib, the cold air channel is connected to the air duct through the connecting vent, and when the shelf is constructed to be installed on the other of the first supporting rib and the second supporting rib, the refrigerated compartment is connected to the air duct through the connecting vent.

[0017] The above technical solution has the following advantages or beneficial effects: By spacing the first and second support ribs of the support structure, the shelves can be positioned on either the first or second support ribs. The different shelf positions affect the refrigerator's heat exchange method. Thus, the refrigerator has both convection and conduction heat exchange modes, allowing users to select the appropriate heat exchange mode based on their needs. For example, after placing food directly on the shelf, the user can position the shelf on the first support rib. In this case, the cold air passage connects to the air duct via the connecting vent. In this way, the refrigerator's internal heat exchange mode is conduction, preventing odor transfer between the refrigerator and freezer compartments. After placing sealed food on the shelf, the user can position the shelf on the second support rib. In this case, the refrigerator connects to the air duct via the connecting vent. In this way, the refrigerator's internal heat exchange mode is convection. While preventing odor transfer, the cold air directly cools the food on the shelf, helping to quickly cool the food, improving the refrigerator's cooling efficiency and reducing energy consumption. The refrigerator provided in the embodiment of the present application allows users to flexibly adjust the internal configuration of the refrigerator according to different storage needs and environmental conditions, thereby improving user experience and operational convenience.

[0018] In some embodiments of the present application, there are multiple shelves; the multiple shelves are arranged at intervals along the height direction of the refrigerator.

[0019] There are multiple connecting vents; along the bottom to the top of the refrigerator, the multiple connecting vents are arranged at intervals, and the cross-sectional areas of the connecting vents gradually increase.

[0020] The multiple shelves and the multiple connecting vents are arranged in a one-to-one correspondence.

[0021] The above technical solution has the following advantages or beneficial effects: Taking into account the characteristics of air flow, the cold air flow rate in the air duct decreases closer to the top of the refrigerator. By arranging the connecting vents with a gradually increasing cross-sectional area from the bottom to the top of the refrigerator, an adequate supply of cold air is ensured in the area near the top of the refrigerator, avoiding the problem of high temperatures in the top area and improving the overall cooling efficiency of the refrigerator.

[0022] In some embodiments of the present application, the box body further includes a refrigerated box liner, which is constructed to form a chamber opening toward the door body.

[0023] The air duct assembly includes an air duct cover plate, which is disposed in the chamber of the refrigerator liner. A connecting vent is formed on the air duct cover plate. The air duct cover plate is opposite to the rear wall of the refrigerator liner and is spaced apart to form a portion of the air duct.

[0024] The above technical solution has the following advantages or beneficial effects: the air duct cover can be a thin aluminum plate. The thin aluminum plate helps to reduce the internal space of the refrigerator liner occupied by the air duct cover, thereby increasing the effective storage capacity inside the refrigerator.

[0025] In addition, the air duct cover has high thermal conductivity. This allows it to effectively transfer cold air and help maintain the temperature inside the refrigerator. This helps improve cooling efficiency and preserve food freshness.

[0026] In some embodiments of the present application, the refrigerator further includes a sealing strip, which is disposed in the air duct; the sealing strip is connected to the air duct cover; and the sealing strip extends along the height direction of the refrigerator.

[0027] Along the width direction of the refrigerator, a sealing strip separates the air duct into a supply air duct and a return air duct.

[0028] The above technical solution has the following advantages or beneficial effects: By providing a sealing strip, the sealing strip separates the air duct into a supply air duct and a return air duct. In this case, the flow path of the cold air cooled by the refrigeration system is: supply air duct, supply air vent, cold air channel, return air vent, return air duct, refrigeration system. Alternatively, the flow path of the cold air cooled by the refrigeration system is: supply air duct, supply air vent, cold storage compartment, return air vent, return air duct, refrigeration system. A closed-loop air circulation system is formed inside the refrigerator. The closed-loop air circulation system allows the cold storage compartment to quickly return to the set temperature, especially when the refrigerator door is frequently opened, maintaining the freshness of food. The closed-loop air circulation helps to remove excess moisture, reduce frost, and maintain an appropriate humidity level, extending the shelf life of food.

[0029] In some embodiments of the present application, there are multiple sealing strips; along the width direction of the refrigerator, the sealing strips separate the air duct into one supply air duct and two return air ducts; the two return air ducts are located on both sides of the supply air duct.

[0030] The above technical solution has the following advantages or beneficial effects: Along the width of the refrigerator, the supply duct is located in the middle, with the two return ducts located on either side of the supply duct. Placing the supply duct in the middle of the two return ducts ensures that cold air can be evenly distributed to both sides. Placing the two return ducts on either side of the supply duct ensures that air that exchanges heat with the refrigerated compartment is quickly recovered. This central supply and dual return arrangement creates a closed-loop air circulation system, improving the efficiency of air flow within the refrigerated compartment and enhancing cooling efficiency.

[0031] In some embodiments of the present application, the cold air channel includes:

[0032] A first channel is provided in the middle of the shelf along the width direction of the refrigerator; the first channel extends along the depth direction of the refrigerator; a side of the first channel facing away from the door body is used to communicate with the air supply duct;

[0033] A second channel is provided at an end of the shelf close to the door; the second channel extends along the width of the refrigerator; and the second channel is used to communicate with a side of the first channel close to the door;

[0034] The third channel, there are two third channels; along the width direction of the refrigerator, the two third channels are arranged on both sides of the first channel; the third channel extends along the depth direction of the refrigerator; the opposite ends of the second channel are respectively connected to the side of the two third channels close to the door body, and the side of the third channel away from the door body is used to connect with the return air duct.

[0035] The above technical solution has the following advantages or beneficial effects: cold air enters through the first channel and is distributed to the shelf area near the door through the second channel. The third channel is responsible for directing air in the cold air channel back to the return air duct. This ensures uniform temperature throughout the shelf and reduces temperature gradients. This layout forms a closed-loop air circulation system, ensuring that cold air effectively covers every area of ​​the shelf and quickly directs hot air back to the refrigeration system. The efficient air circulation system allows the refrigerated compartment to quickly return to the set temperature, especially when the refrigerator door is frequently opened, maintaining the freshness of food.

[0036] In some embodiments of the present application, the cold air channel further includes:

[0037] At least one auxiliary channel is provided, and along the width direction of the refrigerator, the auxiliary channel is located between the first channel and the third channel.

[0038] The auxiliary channel includes a first channel section, a second channel section and a third channel section connected in sequence; the first channel section is used to communicate with the supply air duct, and the first channel section extends along the depth direction of the refrigerator; the second channel section extends along the width direction of the refrigerator; the third channel section extends along the depth direction of the refrigerator, and the third channel section is used to communicate with the return air duct.

[0039] The above technical solution has the following advantages or beneficial effects: the first section of the auxiliary channel directly connects to the supply vent, ensuring that cold air can quickly enter the refrigerated compartment; the third section directly connects to the return vent, ensuring that hot air can be quickly recovered. The auxiliary channel provides an additional air flow path, increasing the distribution channel for cold air and the area of ​​the cold air channel on the shelves, improving temperature consistency on the shelves, reducing temperature unevenness on the shelves, and improving food preservation.

[0040] In a second aspect, an embodiment of the present application provides a refrigerator, comprising:

[0041] The box body is used to construct the refrigeration compartment, which includes the cold storage compartment and the freezer compartment;

[0042] The door is connected to the cabinet to open and close the refrigeration compartment;

[0043] An air duct assembly is constructed to form an air duct; the air duct is communicated with the refrigeration compartment and the freezing compartment respectively;

[0044] Shelves are located in the cold storage room; the shelf structure forms a cold air channel;

[0045] Wherein, connecting vents are arranged on the cavity wall of the refrigerating compartment, and the connecting vents connect the air duct and the cold air channel.

[0046] The shelves are sealed to the cavity wall of the refrigerated compartment, and the shelves are sealed to the door body.

[0047] The above technical solution has the following advantages or beneficial effects: by sealingly connecting the shelves and the refrigerated chamber, the shelves divide the refrigerated chamber into different spaces. After the refrigerator door is closed, the different spaces are relatively separated, and adjacent spaces are not interconnected, thereby avoiding the flow of air between adjacent spaces and avoiding the cross-flavoring of adjacent spaces, effectively preventing the odors of foods in different spaces from affecting each other, and maintaining the original flavor of each food.

[0048] In some embodiments of the present application, the cavity wall of the refrigerated compartment includes a first side wall and a second side wall that are opposite and spaced apart along the width direction of the refrigerator. A supporting structure is provided on the first side wall and the second side wall, and the shelf abuts against the supporting structure.

[0049] The cavity wall of the refrigeration compartment also includes a rear side wall. Along the depth direction of the refrigerator, the rear side wall and the door body are arranged opposite to each other; the shelf and the rear side wall are sealed and connected.

[0050] The above technical solution has the following advantages or beneficial effects: The support structure design allows the shelves to be adjusted at different heights, providing flexible storage options. When installed, the shelves fit tightly against the rear sidewall, forming a sealed interface. This design prevents cold air from leaking through the gap between the shelves and the rear sidewall, thus avoiding airflow and odor transfer between adjacent spaces.

[0051] In some embodiments of the present application, the refrigerator further comprises a sealing member, which is arranged on a side of the shelf close to the door. When the door is closed, the sealing member contacts the door.

[0052] The sealing member extends along the width direction of the refrigerator, and opposite ends of the sealing member abut against the cavity wall of the refrigerating compartment.

[0053] The above technical solution has the following advantages or beneficial effects: The seal extending along the width of the refrigerator forms a continuous sealed barrier within the refrigerator's refrigerated compartment. This design effectively prevents cold air from escaping through the side gaps of the refrigerated compartment, enhancing the refrigerator's overall sealing performance and preventing airflow and odor transfer between adjacent compartments.

[0075] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0076] It should be noted that the brief descriptions of terms in this application are only for the purpose of facilitating the understanding of the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and usual meanings.

[0077] In addition, the terms "comprises" and "comprising" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0078] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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 cannot be understood as a limitation on this application.

[0079] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0080] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0081] In the refrigerator industry, heat exchange primarily occurs through convection and conduction. Convection heat exchange occurs primarily through air circulation. Cold air flows from the refrigeration system, passes through various parts of the refrigerator, absorbs heat from food and other items, and then returns to the refrigeration system for further cooling. Conduction heat exchange occurs primarily through direct contact between objects. The cold air flowing out of the refrigeration system enters the cold air ducts of the shelves, where the cold air is transferred through the shelves to the food or items on them.

[0082] The researchers behind this application considered introducing the cold air generated by the refrigeration system into either the freezer compartment or the refrigerator compartment for convection heat exchange, while the other compartment utilizes conduction heat exchange. Because the freezer compartment requires a greater amount of cooling than the refrigerator compartment, the freezer compartment is connected to the evaporator chamber, where the evaporator is located, via an air duct. This allows the cool air in the evaporator chamber to enter the freezer compartment under the influence of the fan in the duct, creating a frozen storage environment in the freezer compartment.

[0083] For the cold storage room, the researchers of this application set up a cold air channel in the shelf, which is connected to the air duct, so that cold air enters the cold air channel in the shelf and exchanges heat with the cold storage room to achieve a refrigerated storage environment in the cold storage room.

[0084] Convection heat transfer, due to its faster air flow, can quickly adjust the refrigerator's internal temperature to meet changing temperatures. However, convection heat transfer can easily lead to odor transfer. Conduction heat transfer, on the other hand, relies on contact surfaces to transfer cooling energy, which can lead to uneven temperature distribution inside the refrigerator.

[0085] In actual refrigerator usage, users have a wide variety of storage options. To prevent food from tainting each other, more and more people are packaging items individually in bags and boxes. So, how can refrigerators combine both convection and conduction heat transfer?

[0086] One feasible way is to arrange an additional air duct in the refrigerator. A valve is provided in the additional air duct, and by controlling the valve, one of the convection heat exchange or conduction heat exchange modes can be selected.

[0087] However, this approach not only increases the design complexity of the air duct and valve, which may lead to increased manufacturing and maintenance costs, but also the additional air duct takes up storage space.

[0088] To this end, the researchers of this application continued their research and constructed first and second supporting ribs spaced apart on the cavity wall of the cold storage compartment, wherein the shelf is constructed to be selectively installed on the first supporting rib or the second supporting rib, and when the shelf is constructed to be installed on one of the first and second supporting ribs, the cold air channel is connected to the air duct through the connecting vent, and when the shelf is constructed to be installed on the other of the first and second supporting ribs, the cold storage compartment is connected to the air duct through the connecting vent.

[0089] One heat exchange method in refrigerators involves cold air entering the cold air duct through the connecting vents. The cold air then flows through the duct, where the shelves transfer the cold air from the duct to the food, or transfer the cold air from the duct to the refrigerated compartment, keeping the food stored at a low temperature. This heat exchange method prevents food from transferring odors because the cold air doesn't come into direct contact with the food.

[0090] Another heat exchange method in refrigerators is to draw cold air directly into the refrigerator compartment through the connecting vents. This cool air directly cools the food on the shelves, quickly lowering the refrigerator compartment temperature. This heat exchange method improves the refrigerator's cooling efficiency.

[0091] The refrigerator provided in the embodiments of the present application allows the user to adjust the position of the shelves on the support structure and select the refrigerator's heat exchange method. The user can choose a heat exchange method that prevents odor transfer or a heat exchange method that increases cooling efficiency based on food storage requirements. The refrigerator provided in the embodiments of the present application allows the user to flexibly adjust the internal configuration of the refrigerator based on different storage needs and environmental conditions, providing a better user experience and operational convenience.

[0092] Furthermore, the problem of odor transfer in the refrigerator is not only between the freezer compartment and the refrigerator compartment, but also between the spaces formed between different shelves in the refrigerator compartment.

[0093] One solution to the problem of odor transfer between different shelves is to install sealed drawers. However, if each layer of the refrigerated compartment uses sealed drawers, it will be extremely inconvenient to take out food, especially the food on the top shelf of the refrigerated compartment, which also affects the user experience.

[0094] To this end, the researchers behind this application continued their research, sealing the shelves to the walls of the refrigerated compartment and the door. The shelves divide the refrigerated compartment into distinct spaces, isolating adjacent spaces and preventing airflow between them. This effectively prevents the odors of foods stored on different shelves from interfering with each other, preserving the original flavor of each food. Furthermore, by restricting airflow, the risk of bacteria and other microorganisms spreading between different spaces is reduced, thereby reducing the possibility of cross-contamination and improving food safety.

[0095] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0096] Reference Figures 1 to 10 As shown, the embodiment of the present application provides a refrigerator. The height direction of the refrigerator is referenced to Figure 1 The direction indicated by Z. The width direction of the refrigerator refers to Figure 1 The depth of the refrigerator is shown in the direction of X. Figure 1 The direction shown in Y.

[0097] The refrigerator includes a housing 100 , which is configured to form a refrigeration compartment. The refrigeration compartment includes a refrigeration compartment 110 and a freezer compartment 130 .

[0098] The refrigerator further comprises a door body which is connected to the housing 100 to open and close the refrigeration compartment.

[0099] The refrigerator further includes an air duct assembly that forms an air duct 120 , which is in communication with the refrigerating compartment 110 and the freezing compartment 130 .

[0100] The refrigerator further includes a refrigeration system 500 . The refrigeration system 500 is disposed in the housing 100 and is used to provide cold energy for the refrigerating compartment 110 and the freezing compartment 130 .

[0101] The refrigerator further includes a shelf 300 . The shelf 300 is located in the refrigerating compartment 110 ; the shelf 300 is configured to form a cold air passage 310 .

[0102] A support structure 400 is formed on the wall of the refrigerated compartment 110. The support structure 400 includes:

[0103] The first supporting ribs 410 support the shelf 300 in the refrigerated compartment 110;

[0104] The second supporting ribs 420 support the shelf 300 in the refrigerating compartment 110 , and the second supporting ribs 420 and the first supporting ribs 410 are spaced apart along the height direction of the refrigerator.

[0105] A connecting vent 210 is provided on the cavity wall of the refrigerating chamber 110 , and the connecting vent 210 is in communication with the air duct 120 .

[0106] In which, the shelf 300 is constructed to be selectively installed on the first supporting rib 410 or the second supporting rib 420, and when the shelf 300 is constructed to be installed on one of the first supporting rib 410 and the second supporting rib 420, the cold air channel 310 is connected to the air duct 120 through the connecting vent 210, and when the shelf 300 is constructed to be installed on the other of the first supporting rib 410 and the second supporting rib 420, the refrigerated compartment 110 is connected to the air duct 120 through the connecting vent 210.

[0107] In some embodiments, reference Figure 1 and Figure 4 As shown, the shelf 300 is mounted on the first support rib 410. The cold air duct 310 communicates with the air duct 120 via the air inlet. During the refrigerator's cooling process, cold air enters the cold air duct 310 through the connecting vent 210. The cold air flows within the cold air duct 310, and the shelf 300 transfers the cold air's cooling energy to the refrigerated compartment 110, achieving conductive heat exchange within the refrigerator.

[0108] In other embodiments, referring to Figure 5 As shown, the shelf 300 is mounted on the second support rib 420. The refrigerated compartment 110 is connected to the air duct 120 via the air inlet vent. During the refrigerator's cooling process, cold air enters the refrigerated compartment 110 directly through the air inlet vent, directly cooling the food in the refrigerated compartment 110. This convective heat transfer allows the refrigerator to quickly lower the temperature of the refrigerated compartment 110.

[0109] The refrigerator provided in the embodiment of the present application utilizes a support structure 400 with first and second support ribs 410 and 420 spaced apart. This allows the shelf 300 to be positioned either on the first or second support ribs 410. The different positions of the shelf 300 affect the refrigerator's heat exchange method. This allows the refrigerator to utilize both convection and conduction heat exchange methods, allowing users to select the most appropriate heat exchange method based on their needs. For example, after placing food directly on the shelf 300, the user can position the shelf 300 on the first support rib 410. This allows the refrigerator to utilize conduction heat exchange, thus avoiding odor transfer between the refrigerator compartment 110 and the freezer compartment 130. After placing sealed food on the shelf 300, the user can position the shelf 300 on the second support rib 420. This allows the refrigerator to utilize convection heat exchange, allowing cold air to directly cool the food on the shelf 300. This helps to quickly cool the food, improves the refrigerator's cooling efficiency, and reduces energy consumption. At the same time, since the food is sealed, the problem of food odor transfer can also be avoided. The refrigerator provided by the embodiment of the present application allows users to flexibly adjust the internal configuration of the refrigerator according to different storage needs and environmental conditions, providing a better user experience and operational convenience.

[0110] Illustratively, refrigeration system 500 includes an evaporator 510 and a fan 520. The evaporator 510 in refrigeration system 500 is responsible for absorbing heat. Refrigerant evaporates in evaporator 510, absorbing heat from the surrounding environment and lowering the temperature within air duct 120. Fan 520 propels cool air through air duct 120. Air duct 120 directs some of the cool air to the refrigerated compartment 110, providing a suitable refrigerated temperature. By adjusting the speed of fan 520 and opening and closing air duct 120, the temperatures of the refrigerated compartment 110 and freezer compartment 130 can be controlled to meet different storage requirements.

[0111] For example, the refrigerator compartment 110 and the freezer compartment 130 of the refrigerator provided in the embodiment of the present application share a single refrigeration system 500, reducing the number of mechanical components required within the refrigerator, thereby freeing up more storage space and increasing the storage capacity available to the user. Because the refrigerator compartment 110 and the freezer compartment 130 are cooled by the same refrigeration system 500, temperature control is more consistent, reducing temperature fluctuations and ensuring food freshness. Furthermore, because the refrigerator only has a single refrigeration system 500 in operation, the overall noise level of the refrigerator is generally reduced, providing a quieter home environment.

[0112] As a feasible implementation method, refer to Figures 4 to 7 As shown, there are multiple shelves 300; along the height direction of the refrigerator, the multiple shelves 300 are arranged at intervals.

[0113] There are multiple connecting vents 210; along the bottom to the top of the refrigerator, the multiple connecting vents 210 are arranged at intervals, and the cross-sectional areas of the connecting vents 210 gradually increase.

[0114] The plurality of shelves 300 and the plurality of connecting vents 210 are arranged in a one-to-one correspondence.

[0115] Taking into account the characteristics of air flow, the cold air flow in the air duct 120 decreases as it approaches the top of the refrigerator. By arranging the connecting vents 210 with a gradually increasing cross-sectional area from the bottom to the top of the refrigerator, this ensures an adequate supply of cold air to the top of the refrigerator compartment 110, preventing high temperatures in the top area and improving the overall cooling efficiency of the refrigerator.

[0116] As a feasible implementation, the box body 100 further includes a refrigerated box liner, which is structured to form a chamber opening toward the door body.

[0117] The air duct assembly includes an air duct cover plate 200 , which is disposed in the chamber of the refrigerator. A connecting vent 210 is formed on the air duct cover plate 200 .

[0118] The air duct cover 200 is opposite to the rear wall of the refrigerator container and spaced apart from each other to form a portion of the air duct 120 .

[0119] For example, the air duct cover 200 may be a thin aluminum plate. The thin aluminum plate helps to reduce the internal space of the refrigerator liner occupied by the air duct cover 200, thereby increasing the effective storage capacity inside the refrigerator.

[0120] In addition, the air duct cover 200 has a high thermal conductivity. This allows the air duct cover 200 to transfer cold air more efficiently, helping to maintain a uniform temperature inside the refrigerator. This helps improve refrigeration efficiency and preserve food freshness.

[0121] As a feasible implementation method, refer to Figure 8 As shown, the refrigerator further includes a sealing strip 600, which is disposed in the air duct 120; the sealing strip 600 is connected to the air duct cover 200; and the sealing strip 600 extends along the height direction of the refrigerator.

[0122] Along the width of the refrigerator, a sealing strip 600 divides the air duct 120 into a supply air duct 121 and a return air duct 122. Exemplarily, the connecting vents 210 include a supply air duct 211 and a return air duct 212. There are multiple supply air ducts 211. These multiple supply air ducts 211 are spaced apart along the height of the refrigerator. The cross-sectional area of ​​the supply air ducts 211 gradually increases from the bottom to the top of the refrigerator.

[0123] There are a plurality of return air vents 212. Along the height direction of the refrigerator, the plurality of return air vents 212 are spaced apart. Along the bottom to the top direction of the refrigerator, the cross-sectional area of ​​the return air vents 212 gradually increases.

[0124] The plurality of air supply vents 211 and the plurality of air return vents 212 are arranged in a one-to-one correspondence. The air supply vents 211 are communicated with the air supply duct 121. The air return vents 212 are communicated with the air return duct 122.

[0125] By providing multiple supply vents 211 and multiple return vents 212, cold air can be distributed throughout the refrigerator compartment 110, ensuring that the food in the refrigerator compartment 110 is effectively cooled. By arranging the supply vents 211 and return vents 212 from the bottom to the top of the refrigerator, with their cross-sectional areas gradually increasing, an adequate supply of cold air is ensured in the area near the top of the refrigerator compartment 110, avoiding the problem of high temperatures in the top area and improving overall cooling efficiency.

[0126] In some embodiments, the flow path of the cold air cooled by the refrigeration system 500 is: the supply air duct 121 , the supply air vent 211 , the cold air channel 310 , the return air vent 212 , the return air duct 122 , and the refrigeration system 500 .

[0127] In other embodiments, the flow path of the cold air cooled by the refrigeration system 500 is: the supply air duct 121 , the supply air vent 211 , the refrigeration compartment 110 , the return air vent 212 , the return air duct 122 , and the refrigeration system 500 .

[0128] This creates a closed-loop air circulation system within the refrigerator. This system allows the refrigerated compartment 110 to quickly return to its set temperature, maintaining food freshness, especially when the refrigerator door is frequently opened. This closed-loop air circulation helps remove excess moisture, reduces frost formation, and maintains an appropriate humidity level, extending food freshness.

[0129] Exemplarily, air duct 120 includes a refrigeration duct and a freezing duct. The refrigeration duct communicates with refrigeration compartment 110. The freezing duct communicates with freezing compartment 130. The freezing duct communicates with supply duct 121 via supply air duct 800. The freezing duct communicates with return air duct 122 via return air duct 900. An automatic damper is provided within supply air duct 800 to control the opening and closing of airflow.

[0130] As a feasible implementation method, refer to Figure 8 As shown, there are multiple sealing strips 600 ; along the width direction of the refrigerator, the sealing strip 600 separates the air duct 120 into a supply air duct 121 and two return air ducts 122 ; the two return air ducts 122 are located on both sides of the supply air duct 121 .

[0131] Exemplarily, there are two sealing strips 600. The two sealing strips 600 are spaced apart along the width direction of the refrigerator. The sealing strips 600 divide the air duct 120 into three channels. Among them, there is one supply air duct 121. There are two return air ducts 122. Along the width direction of the refrigerator, the supply air duct 121 is located in the middle, and the two return air ducts 122 are located on both sides of the supply air duct 121. By arranging the supply air duct 121 in the middle of the two return air ducts 122, it is ensured that the cold air can be evenly diffused to both sides. The two return air ducts 122 are arranged on both sides of the supply air duct 121 to ensure that the air that exchanges heat with the refrigerated compartment 110 can be quickly recovered. This layout of central air supply and return air on both sides forms a closed-loop air circulation system, which improves the efficiency of air flow in the refrigerated compartment 110 and improves cooling efficiency.

[0132] As a feasible implementation method, refer to Figure 9 As shown, the cold air channel 310 includes a first channel 311 , a second channel 312 and a third channel 313 .

[0133] A first channel 311 is located in the middle of the shelf 300 along the width of the refrigerator. The first channel 311 extends along the depth of the refrigerator. The side of the first channel 311 facing away from the door is connected to the air supply duct 121. The first channel 311 is responsible for transporting cold air from the air supply duct 121 to the shelf 300.

[0134] Second channel 312 is located at the end of shelf 300 near the door. Second channel 312 extends along the width of the refrigerator. Second channel 312 communicates with the side of first channel 311 near the door. Second channel 312 distributes the cold air delivered by first channel 311 to the front area of ​​shelf 300.

[0135] The third channel 313 is connected to the return air vent 212. There are two third channels 313. Along the width direction of the refrigerator, the two third channels 313 are arranged on both sides of the first channel 311. The third channel 313 extends along the depth direction of the refrigerator. The opposite ends of the second channel 312 are respectively connected to the side of the two third channels 313 close to the door body. The side of the third channel 313 facing away from the door body is used to communicate with the return air duct 122. The third channel 313 is responsible for guiding the air in the cold air channel 310 back to the return air duct 122.

[0136] Cold air enters through the first channel 311 and is distributed to the area of ​​the shelf 300 near the door through the second channel 312. The third channel 313 is responsible for directing the air in the cold air channel 310 back to the return air duct 122, ensuring a uniform temperature throughout the shelf 300 and reducing temperature gradients. This layout forms a closed-loop air circulation system, ensuring that cold air effectively covers every area of ​​the shelf 300 and quickly directs hot air back to the refrigeration system 500. This efficient air circulation system allows the refrigerated compartment 110 to quickly return to the set temperature, especially when the refrigerator door is frequently opened, maintaining the freshness of food.

[0137] As a feasible implementation method, refer to Figure 10 As shown, the cold air channel 310 further includes an auxiliary channel 320 .

[0138] The auxiliary passage 320 is located between the first passage 311 and the third passage 313 along the width direction of the refrigerator.

[0139] The auxiliary channel 320 includes a first channel section, a second channel section, and a third channel section, which are connected in sequence. The first channel section communicates with the supply air duct 121 and extends along the depth of the refrigerator. The second channel section extends along the width of the refrigerator. The third channel section extends along the depth of the refrigerator and communicates with the return air duct 122.

[0140] The first section of the auxiliary duct 320 communicates directly with the supply vent 211, ensuring that cold air can quickly enter the refrigerated compartment 110. The third section communicates directly with the return vent 212, ensuring that hot air can be quickly recovered. The auxiliary duct 320 provides an additional air flow path, increasing the distribution channels for cold air and the area of ​​the cold air duct 310 of the shelf 300. This improves temperature consistency across the shelf 300, reduces temperature unevenness across the shelf 300, and enhances food preservation.

[0141] In some embodiments, when storing strongly smelling foods such as durian or stinky tofu, to prevent odor transfer between foods in different storage compartments, the shelves 300 are positioned on the first support ribs 410, and the cold air duct 310 is connected to the air duct 120 via the connecting vent 210. This directs cold air through the cold air duct 310, allowing the refrigerator to cool via conduction heat exchange, effectively preventing the spread of odors from strongly smelling foods such as durian or stinky tofu. This helps preserve the original flavor of other foods in the refrigerator.

[0142] In other embodiments, when the refrigerator stores sealed food, such as bagged milk or bottled cola, to improve the refrigerator's cooling efficiency, the shelves 300 are positioned on the second support ribs 420, and the refrigerated compartment 110 is connected to the air duct 120 via the connecting vent 210. This allows cold air to enter the storage compartment directly, and the refrigerator cools the food via convection heat transfer, rapidly cooling the food stored in the refrigerator while preventing the risk of odor transfer between foods.

[0143] Furthermore, in the refrigerator provided in the embodiment of the present application, the shelf 300 is sealedly connected to the wall of the refrigerating compartment 110, and the shelf 300 is sealedly connected to the door.

[0144] By sealingly connecting the shelf 300 and the refrigeration chamber, the shelf 300 divides the refrigeration compartment 110 into different spaces. After the refrigerator door is closed, the different spaces are relatively separated, and adjacent spaces are not interconnected, thereby avoiding the flow of air between adjacent spaces and the cross-flavoring of adjacent spaces, effectively preventing the odors of foods in different spaces from affecting each other, and maintaining the original flavor of each food.

[0145] In one practicable embodiment, the walls of the refrigerated compartment 110 include a first side wall and a second side wall that are spaced apart and opposite each other along the width of the refrigerator. A support structure 400 is provided on the first and second side walls, and the shelves 300 abut against the support structure 400. The design of the support structure 400 allows the shelves 300 to be adjusted to different heights, providing flexible storage options.

[0146] The refrigerated compartment 110 also includes a rear sidewall, which is positioned opposite the door along the depth of the refrigerator. The shelf 300 is hermetically connected to the rear sidewall. This means that when installed, the shelf 300 fits tightly against the rear sidewall, forming a sealed interface. This design prevents cold air from leaking through the gap between the shelf 300 and the rear sidewall.

[0147] As a feasible embodiment, the refrigerator further includes a sealing member 700, which is disposed on a side of the shelf 300 close to the door. When the door is closed, the sealing member 700 contacts the door.

[0148] The sealing member 700 extends along the width direction of the refrigerator, and opposite ends of the sealing member 700 abut against the inner wall of the inner container.

[0149] The seal 700 extending along the width direction of the refrigerator forms a continuous sealing barrier in the refrigerator refrigeration compartment 110. This design effectively prevents cold air from escaping from the side gaps of the refrigeration compartment 110, thereby enhancing the overall sealing performance of the refrigerator.

[0150] Illustratively, the sealing member 700 may be a sealing strip.

[0151] In some embodiments, a door shelf is provided on the door body for storing food. The shelf 300 is sealed to the door body. The door shelf extends along the height of the refrigerator to a height less than the height between adjacent shelves 300. This ensures that the door shelf does not affect the seal between adjacent shelves 300, thereby improving the seal between different shelves 300.

[0152] In other embodiments, the door body is not provided with a door shelf. The shelf 300 is sealedly connected to the door body.
