Description

Technical Field

[0001] This application relates to the field of refrigeration technology, and more particularly to a refrigerator. Background Technology

[0002] Consumers' pursuit of quality has intensified, leading to more refined differentiation in refrigerator door types. For example, French door refrigerators are the preferred choice in the mid-to-high-end market due to their high utilization of horizontal space and large capacity. Meanwhile, cross-door refrigerators, with their precise storage compartments, are particularly popular in families with infants and young children, and for storing medications.

[0003] In related technologies, a refrigerator includes a cabinet and an air duct assembly and a drawer assembly located within the cabinet. The air duct assembly is used to supply air to the drawer assembly.

[0004] However, the air outlet position of the air duct assembly varies in different types of refrigerators, resulting in poor versatility of the air duct assembly. Utility Model Content

[0005] This application provides a refrigerator with a versatile air duct assembly.

[0006] In a first aspect, this application provides a refrigerator, comprising:

[0007] The container is equipped with a storage compartment.

[0008] The air duct assembly is located in the storage compartment and divides the storage compartment into a cold source compartment and a refrigeration compartment.

[0009] The air duct components include:

[0010] The air duct body is constructed to form an air duct cavity. A first air outlet structure is provided on the front side of the air duct body, and the opening of the first air outlet structure is connected to the air duct cavity.

[0011] The air guide cover has an air inlet structure and a second air outlet structure. The air guide cover can be selectively connected to the air duct body so that the air inlet structure is connected to or not connected to the first air outlet structure.

[0012] The refrigerator provided in this application, when the air duct body is not equipped with an air guide cover, can meet the air outlet position requirements of one type of refrigerator. When the air duct body is equipped with an air guide cover, the air outlet position can be changed along the height or width direction, thereby meeting the air outlet requirements of another type of refrigerator. In this way, the air duct assembly has good versatility.

[0013] In some embodiments, when the air guide cover is connected to the air duct body, the air guide cover is located on the front side of the air duct body, and the air guide cover and the air duct body enclose a first air guide cavity. The opening of the air inlet structure and the opening of the second air outlet structure are both connected to the first air guide cavity.

[0014] In this way, the air guide cover is positioned on the front side of the air duct body. Compared to placing the air guide cover at the bottom of the air duct body, the air duct body in this embodiment can be larger along the height of the housing, thereby increasing the size of the cold source chamber and providing more installation space for components such as the evaporator. The evaporator can be larger, which is beneficial for improving the cooling capacity.

[0015] In some embodiments, when the air guide cover is connected to the air duct body, the second air outlet structure is located below the air inlet structure, and the air inlet structure is connected to the first air outlet structure.

[0016] This helps to solve the problem of interchangeable air duct components in cross-door refrigerators and French door refrigerators.

[0017] In some embodiments, when the air guide cover is connected to the air duct body, the second air outlet structure is located on one side of the air inlet structure along the width direction, and the air inlet structure is connected to the first air outlet structure.

[0018] This helps to solve the problem of interchangeable air duct components between refrigerators with ice makers and variable temperature drawers and refrigerators with variable temperature drawers and fruit and vegetable drawers.

[0019] In some embodiments, a first air guide is provided on the front side of the air duct body, the first air guide is provided at the bottom of the first air outlet structure, the first air guide is provided with a second air guide cavity, and the second air guide cavity is connected to the opening of the first air outlet structure.

[0020] In this way, the direction of airflow can be guided by the first air guide component.

[0021] In some embodiments, when the air guide cover is connected to the air duct body, the air guide cover is placed over the opening of the first air guide and the first air outlet structure, the air guide cover is detachably connected to the side wall of the second air guide cavity, and the air guide cover, the first air guide and the air duct body together form the first air guide cavity.

[0022] There is an angle between the plane where the opening of the first air outlet structure is located and the extended plane of the air duct body.

[0023] In this way, the first air guide component can function as an air guide both when the air guide cover is not installed and when it is installed, working in conjunction with the air guide cover to guide air. The first air guide component can serve different functions, thus simplifying the structure and reducing costs. Furthermore, the plane containing the opening of the first air outlet structure forms an angle with the extending plane of the duct body, which facilitates the flow of air from the first air outlet structure into the second air guide cavity when the air guide cover is installed.

[0024] In some embodiments, a second air guide is provided on the front side of the air duct body, and the second air guide is located below the first air guide.

[0025] In this way, the direction of airflow can be guided by the second air guide.

[0026] In some embodiments, a seal is provided between the air guide cover and the first air guide member.

[0027] This helps prevent air from flowing out between the air guide cover and the first air guide component, thus reducing air volume loss.

[0028] In some embodiments, a third air outlet structure is provided on the front side of the air duct body, and the third air outlet structure is located above the first air outlet structure along the height direction.

[0029] The top of the third air outlet structure is adjacent to the top of the air duct body.

[0030] This facilitates the flow of cold air within the refrigerated room.

[0031] Secondly, this application provides a refrigerator, comprising:

[0032] The container is equipped with a storage compartment.

[0033] The air duct assembly is located in the storage compartment and divides the storage compartment into a cold source compartment and a refrigeration compartment.

[0034] Drawer assembly, located in the refrigeration compartment; air duct assembly configured to supply air into the drawer assembly;

[0035] The air duct components include:

[0036] The air duct body is constructed to form an air duct cavity, which is connected to the cold source chamber. A first air outlet structure is provided on the front side of the air duct body, and the opening of the first air outlet structure is connected to the air duct cavity and the refrigeration chamber respectively.

[0037] The air guide cover has an air inlet structure and a second air outlet structure. The air guide cover can be selectively connected to the air duct body to match different drawer assembly arrangements.

[0038] In this way, when the air duct body is not equipped with an air guide cover, it can meet the air outlet position requirements of one type of refrigerator. When the air duct body is equipped with an air guide cover, the air outlet position can be changed along the height or width direction to match the air intake requirements of different drawer assembly arrangements, thereby meeting the air outlet requirements of another type of refrigerator. In this way, the air duct assembly has good versatility. Attached Figure Description

[0059] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0060] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0061] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0062] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0063] Among related technologies, French door refrigerators (side-by-side doors + large bottom drawer) are the preferred choice in the mid-to-high-end market due to their high lateral space utilization (unobstructed drawer access) and large capacity (400L and above being the mainstream). Cross-door refrigerators, on the other hand, are particularly popular in scenarios such as families with infants and young children, and for storing medicines, due to their cross-shaped partitions (double refrigerator doors + double freezer drawers) and precise storage capabilities. These two types of refrigerators are currently the mainstream in the market, with comparable demand. Because the drawers in French door and cross-door refrigerators are arranged differently along their height, different air duct components are used to meet the different air outlet requirements along the height, ensuring that the airflow and velocity in each drawer component meet the requirements. However, this design using different air duct components is not conducive to the universality and on-site manufacturability of the air duct components.

[0064] In the related technologies, the first type of refrigerator has an ice maker and a variable-temperature drawer in the refrigeration compartment. The ratio of the ice maker to the variable-temperature drawer along the width of the refrigerator is 3:7, and the ratio is the same along the depth of the refrigerator. The second type of refrigerator has a variable-temperature drawer and a fruit and vegetable drawer in the refrigeration compartment. The ratio of the width of the variable-temperature drawer to the fruit and vegetable drawer is 5:5, and the ratio is the same along the depth of the refrigerator. To achieve precise temperature control of the variable-temperature drawer from -1℃ to -3℃, the air vent is required to be located in the middle of the drawer. The two types of refrigerators use different air duct components to meet different air outlet position requirements along the width direction. This design is not conducive to the universality of the air duct components and on-site manufacturability.

[0065] To address the aforementioned technical problems, this application provides a refrigerator whose air duct assembly includes an air duct body and an air guide cover. The air duct body forms an air duct cavity, and a first air outlet structure is provided on the front side of the air duct body, with the opening of the first air outlet structure communicating with the air duct cavity. The air guide cover is provided with an air inlet structure and a second air outlet structure, and the air guide cover can be selectively connected to the air duct body so that the air inlet structure and the first air outlet structure are connected or not connected. When the air duct body is not equipped with the air guide cover, it can meet the air outlet position requirements of one type of refrigerator. When the air duct body is equipped with the air guide cover, the air outlet position and air outlet angle can be changed along the height or width direction, thereby meeting the air outlet requirements of another type of refrigerator. In this way, the air duct assembly has good versatility.

[0066] This application provides a refrigerator, which is a frost-free refrigerator.

[0067] Figure 1 This is a partial structural schematic diagram of a French-style multi-door refrigerator provided in an embodiment of this application. Figure 2 This is a partial structural diagram of a cross-shaped refrigerator provided in an embodiment of this application.

[0068] See Figure 1 and Figure 2 As shown, in some embodiments, the refrigerator includes a cabinet 100.

[0069] The housing 100 is configured to form a storage compartment. Specifically, the housing 100 includes an outer shell (not shown in the figure), a liner 110, and a press chamber (not shown in the figure).

[0070] The outer casing has a first receiving cavity with a first pick-up and drop-out port and a second pick-up and drop-out port, which are respectively located on opposite sides of the outer casing in the depth direction of the housing 100. The first pick-up and drop-out port can be located on the front side of the outer casing, and the second pick-up and drop-out port can be located on the rear side of the outer casing.

[0071] The compressor compartment is located inside the outer shell, and its opening is opposite to the second access port, allowing the compressor and condenser to be placed inside the compressor compartment via the second access port and the opening. The inner box 110 is located inside the outer shell and forms at least one storage compartment 120. The inner box 110 has a third access port, which is opposite to the first access port, allowing items to be placed into the storage compartment 120 via the third access port and the first access port.

[0072] A foam layer is filled between the inner chamber 110, the outer shell and the compressor chamber. The foam layer is used to insulate the storage compartment 120, thereby ensuring the cooling effect inside the storage compartment 120.

[0073] In some embodiments, the refrigerator includes a door.

[0074] The door is rotatably connected to the cabinet 100 to open or close the storage compartment 120.

[0075] The door is an openable cover located on the front of the cabinet 100 to close and open the storage compartment 120, allowing users to retrieve and place items within the storage compartment 120. It should be noted that the number of doors can be one, two, or more.

[0076] The refrigerator includes a refrigeration system, which may include a compressor, a condenser, a throttling device, and an evaporator 400. The compressor, condenser, throttling device, and evaporator 400 are connected in series via pipes through which refrigerant flows. The compressor and condenser may be located in the compressor compartment, and the evaporator 400 may be located in the cold source chamber 121.

[0077] Figure 3 for Figure 1 sectional view, Figure 4 for Figure 2 A sectional view.

[0078] See Figure 3 and Figure 4 As shown, in some embodiments, the refrigerator includes an air duct assembly 200.

[0079] The air duct assembly 200 is located in the storage compartment 120, dividing the storage compartment 120 into a cold source chamber 121 and a refrigeration chamber 122. The air duct assembly 200 connects the cold source chamber 121 and the refrigeration chamber 122. That is, air in the cold source chamber 121 enters the refrigeration chamber 122 through the air duct assembly 200, and air in the refrigeration chamber 122 enters the cold source chamber 121 through the air duct assembly 200.

[0080] The refrigeration compartment 122 can be at least one. When there is only one refrigeration compartment 122, it can be any one of a refrigerator compartment, a freezer compartment, or a variable temperature compartment. When there are two or more refrigeration compartments 122, the multiple refrigeration compartments 122 can include at least one or more of a refrigerator compartment, a freezer compartment, or a variable temperature compartment.

[0081] When the compressor is working, low-temperature, low-pressure refrigerant is drawn into the compressor and compressed into high-temperature, high-pressure superheated gas in the compressor cylinder before being discharged into the condenser. The high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, and its temperature continuously decreases, gradually being cooled into room-temperature, high-pressure saturated vapor, and further cooled into saturated liquid. The pressure of the refrigerant remains almost constant throughout the entire condensation process.

[0082] The throttling device may include a pressure reducing tube or an electronic expansion valve. In this application, the throttling device is described as including a pressure reducing tube as an example. The pressure reducing tube is low in cost and is not prone to abnormal failure.

[0083] After condensation, the saturated liquid refrigerant is throttled and depressurized through a pressure reducing pipe, turning the refrigerant into room-temperature, low-pressure wet vapor. Then, this room-temperature, low-pressure wet vapor absorbs heat and vaporizes through the evaporator 400, not only lowering the temperature of the evaporator 400 and its surroundings, but also transforming the refrigerant into a low-temperature, low-pressure gas.

[0084] The evaporator 400 cools the air in the cold source chamber 121 to lower the temperature of the air in the cold source chamber 121. Under the action of the fan in the air duct assembly 200, the cold air in the cold source chamber 121 flows to the cooling chamber 122 through the air duct assembly 200 to lower the temperature of the cooling chamber 122.

[0085] The refrigerant from the evaporator 400 returns to the compressor, repeating the above process so that the evaporator 400 can continuously cool the air in the cold source chamber 121, thereby maintaining the refrigeration chamber 122 at the set temperature.

[0086] See Figure 1 and Figure 2 As shown, in some embodiments, the refrigerator includes a drawer assembly 300. The drawer assembly 300 is slidably connected to the refrigerator liner 110.

[0087] The drawer assembly 300 is located in the refrigeration compartment 122. Specifically, the drawer assembly 300 can be located in the freezer compartment, refrigerator compartment, or variable temperature compartment, etc. The drawer assembly 300 can be a variable temperature drawer, a fruit and vegetable drawer, or an ice maker, etc.

[0088] Figure 5 for Figure 1 A structural diagram after removing the drawer components. Figure 6 for Figure 2 A schematic diagram of the structure after removing the drawer components. Figure 7 for Figure 3 A magnified view of a portion of point A in the middle. Figure 8 for Figure 4 A magnified view of a section at point B in the middle.

[0089] See Figures 5 to 8 As shown, in some embodiments, the air duct assembly 200 includes an air duct body 210 and an air guide cover 220.

[0090] The air duct body 210 is constructed to form an air duct cavity 211, which is connected to the cold source chamber 121. A first air outlet structure 212 is provided on the front side of the air duct body 210, and the opening of the first air outlet structure 212 is connected to both the air duct cavity 211 and the refrigeration chamber 122. The first air outlet structure 212 can be used to supply air to the bottom drawer assembly 300.

[0091] It is understandable that by placing the first air outlet structure 212 on the front side of the air duct body 210, compared to placing the first air outlet structure 212 at the bottom, the air duct body 210 in this embodiment can be larger along the height direction of the housing 100, thereby making the size of the cold source chamber 121 larger, providing more installation space for devices such as the evaporator 400, and allowing the evaporator 400 to be larger, which is beneficial to improving the cooling capacity.

[0092] The air guide cover 220 is provided with an air inlet structure 221 and a second air outlet structure 222. The air guide cover 220 can be selectively connected to the air duct body 210 so that the air inlet structure 221 is connected to or not connected to the first air outlet structure 212.

[0093] When the air guide cover 220 is not connected to the air duct body 210, the air in the cold source chamber 121 enters the refrigeration chamber 122 through the air duct chamber 211 and the first air outlet structure 212, and then enters the drawer assembly 300.

[0094] When the air guide cover 220 is connected to the air duct body 210, the air in the cold source chamber 121 enters the refrigeration chamber 122 through the air duct chamber 211, the first air outlet structure 212, the air inlet structure 221 and the second air outlet structure 222, and then enters the drawer assembly 300.

[0095] It is understood that the air duct assembly 200 provided in this application includes an air duct body 210 and an air guide cover 220. The air duct body 210 is configured to form an air duct cavity 211, and a first air outlet structure 212 is provided on the front side of the air duct body 210. The opening of the first air outlet structure 212 communicates with the air duct cavity 211. The air guide cover 220 is provided with an air inlet structure 221 and a second air outlet structure 222. The air guide cover 220 can be selectively connected to the air duct body 210 so that the air inlet structure 221 is connected to or not connected to the first air outlet structure 212. When the air duct body 210 is not equipped with the air guide cover 220, it can meet the air outlet position requirements of one type of refrigerator. When the air duct body 210 is equipped with the air guide cover 220, the air outlet position and air outlet angle can be changed to meet the air outlet requirements of another type of refrigerator. In this way, the air duct assembly 200 has good versatility.

[0096] See Figure 5 As shown, in some embodiments, when the air guide cover 220 is connected to the air duct body 210, the air guide cover 220 is located on the front side of the air duct body 210, and the air guide cover 220 and the air duct body 210 enclose to form a first air guide cavity 230. The opening of the air inlet structure 221 and the opening of the second air outlet structure 222 are both connected to the first air guide cavity 230.

[0097] It is understandable that the air guide cover 220 is positioned on the front side of the air duct body 210. In this way, compared to positioning the air guide cover 220 at the bottom of the air duct body 210, the air duct body 210 in this embodiment can be larger along the height direction of the housing 100, thereby making the size of the cold source chamber 121 larger, providing more installation space for components such as the evaporator 400, and allowing the evaporator 400 to be larger, which is beneficial to improving the cooling capacity.

[0098] See Figure 1 As shown, in some embodiments, the refrigerator is a French door refrigerator.

[0099] Specifically, the French door refrigerator includes multiple drawer assemblies 300. For example, there are three drawer assemblies 300. The three drawer assemblies 300 are spaced apart along the height direction, which is the direction shown by the Z-axis in the figure.

[0100] See Figure 2 As shown, in some embodiments, the refrigerator is a cross-shaped refrigerator.

[0101] Specifically, the French door refrigerator includes multiple drawer assemblies 300. For example, there are seven drawer assemblies 300. These seven drawer assemblies 300 are arranged in two groups along the width direction. One group contains three drawer assemblies 300, spaced apart along the height direction. The other group contains four drawer assemblies 300, also spaced apart along the height direction. The height direction is indicated by the Z-axis in the diagram. The width direction is indicated by the X-axis in the diagram.

[0102] It should be noted that the dimensions of the drawer assemblies 300 along the height direction differ between cross-door refrigerators and French door refrigerators. To ensure that each drawer assembly 300 has an air vent for airflow and that the air velocity and volume within each drawer assembly 300 meet requirements, the air duct assembly 200 in related technologies cannot be interchanged. For example, if the air duct assembly 200 from a multi-door refrigerator is used in a French door refrigerator, the air intake effect of the bottom drawer assembly 300 will be poor.

[0103] To address the issue of the universality of the air duct assembly 200 in cross-door and French door refrigerators, see [link / reference]. Figure 5 As shown, when the refrigerator is a French door refrigerator, the air guide cover 220 of the air duct assembly 200 is connected to the air duct body 210 of the air duct assembly 200.

[0104] Specifically, when the air guide cover 220 is connected to the air duct body 210, the second air outlet structure 222 is located below the air inlet structure 221, and the air inlet structure 221 is connected to the first air outlet structure 212. In this way, the air outlet position can be adjusted downward, thereby meeting the air supply needs of the bottom drawer of the French door refrigerator.

[0105] See Figure 6 As shown, when the refrigerator is a cross-shaped refrigerator, the air guide cover 220 of the air duct assembly 200 is disconnected from the air duct body 210 of the air duct assembly 200. In this way, the first air outlet structure 212 can directly supply air to the bottom drawer assembly 300.

[0106] It should be noted that in some embodiments, when the refrigerator is a cross-door refrigerator, the air guide cover 220 of the air duct assembly 200 is connected to the air duct body 210 of the air duct assembly 200. The air guide cover 220 used for the cross-door refrigerator is different from the air guide cover 220 used for the French door refrigerator. That is, different refrigerators can be equipped with different air guide covers 220. This design results in less air loss and more efficient airflow utilization when supplying air to the last drawer assembly 300. By simply installing different air guide covers 220, individual air supply functions for drawer assemblies 300 of different heights can be achieved. This facilitates the standardization of air duct components, improves on-site installation efficiency, and reduces material costs and mold-making expenses.

[0107] Figure 9This is a schematic diagram of the structure of the refrigerator air duct assembly provided in an embodiment of this application. Figure 10 This is a structural schematic diagram of the refrigerator air duct assembly provided in an embodiment of this application from another angle.

[0108] See Figure 9 and Figure 10 As shown, in some embodiments, the air duct body 210 includes a front cover plate 213 and a rear cover plate 214. The front cover plate 213 and the rear cover plate 214 are connected to each other. The front cover plate 213 and the rear cover plate 214 enclose an air duct cavity 211.

[0109] See Figure 10 As shown, in some embodiments, the air duct assembly 200 includes a fan 215. The fan 215 is used to drive the flow of air.

[0110] The fan 215 is located inside the air duct cavity 211. Specifically, the air duct rear cover 214 is provided with an air intake 2141, and the fan 215 is arranged opposite to the air intake 2141.

[0111] Figure 11 This is a schematic diagram of the structure of the air duct body in the refrigerator provided in an embodiment of this application. Figure 12 This is a front view of the refrigerator's air duct body provided in an embodiment of this application.

[0112] See Figure 11 and Figure 12 As shown, in some embodiments, a third air outlet structure 216 is provided on the front side of the air duct body 210. The third air outlet structure 216 is used to supply air to the drawer assemblies 300 of other layers. For example, the third air outlet structure 216 is used to supply air to the top drawer assembly 300.

[0113] Along the height direction, the third air outlet structure 216 is located above the first air outlet structure 212. Specifically, the third air outlet structure 216 can be installed on the front cover plate 213 of the air duct.

[0114] In some embodiments, the top of the third air outlet structure 216 is adjacent to the top of the air duct body 210.

[0115] Understandably, because cold air sinks, the top of the third air outlet structure 216 is adjacent to the top of the duct body 210. In other words, the proximity of the third air outlet structure 216 to the top of the duct body 210 facilitates the flow of cold air within the cooling compartment 122. For example, the top of the third air outlet structure 216 may be flush with the top of the duct body 210. Alternatively, the top of the third air outlet structure 216 may have a small gap with the top of the duct body 210, for example, a gap of 0 to 50 mm, or a gap less than 10 mm, or a gap less than 25 mm, etc.

[0116] Figure 13 For along Figure 12 A cross-sectional view along the CC direction.

[0117] See Figure 13 As shown, in some embodiments, the third air outlet structure 216 is a direct airflow structure. That is, the air outlet direction of the third air outlet structure 216 is perpendicular to the extension plane of the duct body 210. The extension plane of the duct body 210 is the plane shown by the Z-axis and X-axis in the figure.

[0118] See Figure 11 and Figure 12 As shown, in some embodiments, a fourth air outlet structure 217 is provided on the front side of the air duct body 210. The fourth air outlet structure 217 is used to supply air to the drawer assemblies 300 of other layers. For example, the fourth air outlet structure 217 is used to supply air to the drawer assembly 300 of the middle layer.

[0119] Along the height direction, the fourth air outlet structure 217 is located between the third air outlet structure 216 and the first air outlet structure 212. Specifically, the fourth air outlet structure 217 can be installed on the front cover plate 213 of the air duct.

[0120] See Figure 13 As shown, in some embodiments, the fourth air outlet structure 217 is a direct airflow structure. That is, the air outlet direction of the fourth air outlet structure 217 is perpendicular to the extension plane of the duct body 210. The extension plane of the duct body 210 is the plane shown by the Z-axis and X-axis in the figure.

[0121] In this configuration, the number of fourth air outlet structures 217 along the height direction is at least one. For example, the number of fourth air outlet structures 217 along the height direction can be one or two.

[0122] See Figure 11 and Figure 12 As shown, in some embodiments, a first air guide 218 is provided on the front side of the air duct body 210. The first air guide 218 is located at the bottom of the first air outlet structure 212. The first air guide 218 is provided with a second air guide cavity 2181, and the second air guide cavity 2181 is connected to the opening of the first air outlet structure 212.

[0123] When the air guide cover 220 is not installed, the air in the cold source chamber 121 enters the refrigeration chamber 122 through the air duct chamber 211 and the first air outlet structure 212, and then moves downward along the second air guide chamber 2181. In this way, the airflow direction can be guided by the first air guide 218. The air blown out from the first air outlet structure 212 can blow vertically downward along the first air guide 218, and then enter the bottom drawer assembly 300 along the first air guide 218, so that the bottom drawer assembly 300 can have sufficient airflow for cooling.

[0124] Specifically, the first air guide 218 and the first air outlet structure 212 are arranged in a one-to-one correspondence. That is, the number of first air guides 218 and the number of first air outlet structures 212 are the same. Among them, the first air guide 218 may include two first air guide ribs, which are arranged at intervals along the width direction on opposite sides of the first air outlet structure 212.

[0125] Figure 14 for Figure 11 A magnified view of a section at point D. Figure 15 This is a schematic diagram of the structure of the refrigerator air duct cover provided in an embodiment of this application.

[0126] See Figure 14 and Figure 15 As shown, in some embodiments, when the air guide cover 220 is connected to the air duct body 210, the air guide cover 220 covers the openings of the first air guide member 218 and the first air outlet structure 212. The air guide cover 220 is detachably connected to the side wall of the second air guide cavity 2181. The air guide cover 220, the first air guide member 218, and the air duct body 210 together form the first air guide cavity 230. That is, the second air guide cavity 2181 is a part of the first air guide cavity 230.

[0127] It is understandable that the first air guide component 218 can function as an air guide when the air guide cover 220 is not installed, and it can also function as an air guide in conjunction with the air guide cover 220 when the air guide cover 220 is installed. In this way, the first air guide component 218 can serve different functions, which helps to simplify the structure and reduce costs.

[0128] Specifically, one of the first air guide 218 and the air guide cover 220 is provided with a locking block 240, and the other is provided with a locking groove 250 that matches the locking block 240. The air guide cover 220 and the first air guide 218 are detachably connected through the locking block 240 and the locking groove 250.

[0129] In other embodiments, the first air guide 218 and the air guide cover 220 can be detachably connected by screws.

[0130] See Figure 14 As shown, in some embodiments, the plane containing the opening of the first air outlet structure 212 forms an angle α with the extending plane of the air duct body 210. This facilitates the air outlet of the first air outlet structure 212 entering the second air guide cavity 2181.

[0131] Specifically, a boss 2131 is provided on the front side of the duct front cover 213, protruding from the surface of the duct front cover 213. A first air outlet structure 212 is located at the bottom of the boss 2131. The extending direction of the bottom surface of the boss 2131 forms an angle α with the extending plane of the duct body 210. The extending plane of the duct body 210 is the plane shown by the Z-axis and X-axis in the figure. After the air guide cover 220 is installed, the front side of the air guide cover 220 is flush with the boss 2131.

[0132] In some embodiments, a sealing element is provided between the air guide cover 220 and the first air guide member 218. This helps to prevent air from flowing out from the space between the air guide cover 220 and the first air guide member 218, thereby reducing airflow loss.

[0133] Specifically, the seal can seal sponge or seal rubber, etc.

[0134] See Figure 15 As shown, in some embodiments, the air inlet structure 221 is disposed on the top of the air guide cover 220. The second air outlet structure 222 is disposed on the front side of the air guide cover 220. It should be noted that the second air outlet structure 222 is disposed on the air guide cover 220 according to the height of the drawer assembly 300, and the number of second air outlet structures 222 is at least one. For example, the number of second air outlet structures 222 can be one or two.

[0135] See Figure 5 and Figure 7 As shown, in some embodiments, the second air outlet structure 222 is a direct airflow structure. That is, the air outlet direction of the second air outlet structure 222 is perpendicular to the extension plane of the duct body 210. The extension plane of the duct body 210 is the plane shown by the Z-axis and X-axis in the figure.

[0136] See Figure 11 and Figure 13 As shown, in some embodiments, a second air guide 219 is provided on the front side of the air duct body 210, and the second air guide 219 is located below the first air guide 218. When the air guide cover 220 is not installed, the air in the cold source chamber 121 enters the refrigeration chamber 122 through the air duct cavity 211 and the first air outlet structure 212, and then moves downward along the second air guide cavity 2181 and the second air guide 219. In this way, the airflow direction can be guided by the second air guide 219. The air blown out from the second air guide cavity 2181 can enter the bottom drawer assembly 300 along the second air guide 219, and the bottom drawer assembly 300 can have sufficient airflow for cooling.

[0137] Specifically, the second air guide 219 can be an air guide rib.

[0138] In some embodiments, in the first type of refrigerator, the refrigeration compartment 122 is equipped with an ice maker and a variable-temperature drawer. The ratio of the ice maker to the variable-temperature drawer along the width of the refrigerator is 3:7, and the ratio along the depth of the refrigerator is the same. In the second type of refrigerator, the refrigeration compartment 122 is equipped with a variable-temperature drawer and a fruit and vegetable drawer. The ratio of the width of the variable-temperature drawer to the fruit and vegetable drawer is 5:5, and the ratio along the depth of the refrigerator is the same. Moreover, in order to achieve precise temperature control of the variable-temperature drawer from -1℃ to -3℃, the air vent is required to be arranged in the middle of the drawer.

[0139] Therefore, in order to solve the common problem of the air duct assembly 200 of the two types of refrigerators, when the air guide cover 220 is connected to the air duct body 210, the second air outlet structure 222 is located on one side of the air inlet structure 221 along the width direction, and the air inlet structure 221 is connected to the first air outlet structure 212.

[0140] Understandably, when the air duct body 210 is not equipped with the air guide cover 220, it can meet the air outlet position requirements of one type of refrigerator. When the air duct body 210 is equipped with the air guide cover 220, the air outlet position can be changed in the width direction to meet the air outlet requirements of another type of refrigerator. In this way, the air duct assembly 200 has good versatility.

[0141] In other embodiments, when the air guide cover 220 is connected to the air duct body 210, the second air outlet structure 222 is located on one side of the air inlet structure 221 along the first direction, and the air inlet structure 221 is connected to the first air outlet structure 212. The first direction has an angle with the width direction and an angle with the height direction.
