Description

Technical Field

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

[0002] Frost-free refrigerators use air for cooling. When hot air passes through the built-in evaporator, heat exchange occurs directly between the high-temperature air and the low-temperature evaporator, causing the air temperature to drop. Simultaneously, cold air is blown into each compartment of the refrigerator by a fan through air ducts, further lowering the temperature in each compartment.

[0003] In related technologies, the connection between the refrigerator liner and the air duct component is achieved by securing the air duct component with clips inside the liner. During installation, the clips on the air duct component need to be forcefully pressed into the liner, and the deformation of the liner causes the clips to engage, thus connecting the liner and the air duct component. However, this method of securing is difficult to perform and can easily damage the liner. Utility Model Content

[0004] This application discloses a refrigerator that can maintain the integrity of the inner liner while reducing the use of tools and improving assembly efficiency during screwless installation.

[0005] To achieve the above objectives, embodiments of this application disclose a refrigerator, comprising: Box; The inner liner is disposed in the box body, and the inner liner forms a storage compartment; A door, which is movably connected to the housing to open or close the storage room; An air duct assembly is disposed in the storage chamber and is provided with a first hook; The inner liner includes: The inner liner body includes a first inner wall surface and a second inner wall surface and a third inner wall surface that are opposite each other along the width direction of the box body. The second inner wall surface, the first inner wall surface and the third inner wall surface enclose the storage chamber. A fastening assembly is movably disposed on the first inner wall surface and located in the storage chamber, and a fastening space is formed between the fastening assembly and the first inner wall surface; The fastening component can move relative to the first inner wall surface along a first direction to open the fastening space, so that the first hook can extend into the fastening space along a second direction, and the fastening component can also fasten with the first hook to fix the air duct component to the first inner wall surface. Wherein, the first direction intersects with the second direction.

[0006] The refrigerator of this application forms a fastening space between the first inner wall surface of the inner liner and the fastening component. The fastening component can move relative to the first inner wall surface in a first direction to open the fastening space. Therefore, when the air duct component needs to be installed on the inner liner, the movement of the fastening component allows the first hook to extend into the fastening space in a second direction, and the fastening component can also engage with the first hook, thereby fixing the air duct component to the first inner wall surface. It is evident that the refrigerator of this application achieves a screwless connection between the air duct component and the inner liner, maintaining the integrity of the inner liner while avoiding the damage to the liner that may be caused by traditional clip-on fixing methods. Furthermore, during assembly, the operator only needs to align the first hook of the air duct component with the fastening component and push the fastening component to move in the first direction to open the fastening space. After the first hook extends, the fastening component is released to complete the fixing of the air duct component. This design not only simplifies the assembly process and reduces the use of tools but also improves assembly efficiency and effectively reduces assembly difficulty.

[0007] In some embodiments of this application, the fastening assembly includes: The fastener is movably disposed on the first inner wall surface and forms a fastening space with the first inner wall surface; A reset member, one end of which is connected to the first inner wall surface and the other end of which is connected to the fastener, the reset member being configured to provide a reset force to the fastener to shield the fastening space.

[0008] By creating a locking space between the fastener and the first inner wall surface, and connecting the reset member to the fastener, a locking space is formed. This reset member provides a shielding mechanism to the fastener, ensuring that the locking space remains shielded even when the fastener is in a free state, preventing the entry of foreign objects. When the air duct assembly needs to be installed, simply apply an external force along a first direction to the fastener. The fastener will then overcome the reset force of the reset member and move, thus opening the locking space. At this point, the first hook can smoothly extend into the locking space. Once the first hook is fully extended, release the fastener. The fastener will reset under the reset force of the reset member, re-shielding the locking space and forming a tight lock with the first hook, ensuring that the air duct assembly is securely installed on the inner liner body. This design is not only simple in structure and easy to operate, but also effectively improves the stability and reliability of the connection between the air duct assembly and the inner liner body.

[0009] In some embodiments of this application, the fastener includes: A fixing block is disposed on the first inner wall surface, the fixing block forms a receiving cavity, and the fixing block is provided with a first through hole; A fastening element, wherein the fastening element is configured to be received in the receiving cavity to open the fastening space, and the fastening element is configured to extend out of the receiving cavity to cover the fastening space; The fastening assembly further includes: A push rod, one end of which is connected to the fastening member, and the other end of which is movably inserted through the first through hole, is configured to drive the fastening member to move along the first direction under the action of the reset member, so that the fastening member covers the fastening space.

[0010] The fixing block, serving as the basic support for the fastener, is securely mounted on the first inner wall, providing a reliable installation base for the entire fastening assembly. Simultaneously, the receiving cavity provides space for the fastener's retraction and extension. When the duct assembly needs to be installed, the fastener is retracted into the receiving cavity, opening the fastening space and allowing the first hook to extend smoothly. Once the first hook is fully inserted, the fastener extends out of the receiving cavity, concealing the fastening space and tightly engaging with the first hook to achieve a secure installation of the duct assembly.

[0011] When the fastening space needs to be opened, an external force along the first direction is applied to the push rod. The push rod drives the fastening component to overcome the resetting force of the reset component and move into the receiving cavity, thereby opening the fastening space and facilitating the insertion of the first hook. After the first hook is inserted into place, the push rod is released. The reset component, through the push rod, drives the fastening component to move in the opposite direction along the first direction, causing the fastening component to extend out of the receiving cavity, cover the fastening space, and tightly fasten with the first hook, ensuring the stable installation of the air duct assembly. By setting the push rod to drive the fastening component through the first through hole, the convenience and reliability of the fastening assembly operation are further improved, while ensuring the stability and accuracy of the fastening component's movement, effectively avoiding connection failure caused by fastening component movement deviation.

[0012] In some embodiments of this application, a stop block is provided at one end of the push rod away from the fastener. The stop block is configured to abut against the fixing block when the fastener closes the fastening space to limit the displacement of the fastener along the first direction.

[0013] By setting a stop block at the end of the push rod away from the fastener, when the fastener closes the fastening space under the reset action of the reset member, the stop block abuts against the fixing block to prevent the fastener from extending out of the receiving cavity along the first direction by a distance. This prevents the fastener from coming out of the receiving cavity due to excessive reset, ensuring that the fastener can be accurately reset to the position that covers the fastening space and form a tight and reliable fastening with the first hook. This further improves the stability and reliability of the connection between the air duct assembly and the inner liner body.

[0014] In some embodiments of this application, the first inner wall surface is formed with a groove, and the fixing block is disposed in the groove and forms a gap with the bottom surface of the groove, so that the first through hole and the bottom surface of the groove are spaced apart along the first direction, so as to provide the push rod with displacement space along the first direction.

[0015] A groove is formed on the first inner wall surface, and the fixing block is placed in the groove with a certain distance from the bottom of the groove. This provides displacement space for the push rod in the first direction. When installing the air duct assembly, when an external force is applied to the push rod, the push rod drives the fastening component to move and open the fastening space. The push rod can move smoothly within this displacement space without being obstructed by the first inner wall surface or other structures, ensuring that the fastening assembly can function properly and allowing the first hook to smoothly extend into the fastening space. At the same time, this design also makes reasonable use of the space of the first inner wall surface, making the structure of the entire fastening assembly more compact and not occupying too much effective space in the storage compartment, which is conducive to optimizing the layout of the refrigerator's internal space. Moreover, the groove plays a certain positioning and limiting role for the fixing block, making the installation of the fixing block on the first inner wall surface more stable and less prone to shaking or displacement. This ensures the overall stability and reliability of the fastening assembly, further improving the stability of the connection between the air duct assembly and the inner liner body, and ensuring the stable operation of the refrigerator's refrigeration system.

[0016] In some embodiments of this application, the fastener is provided with a threaded hole, and the outer circumferential surface of the push rod is provided with an external thread, which is threadedly connected to the threaded hole.

[0017] By connecting the threaded hole of the fastener to the external thread of the push rod, a secure connection between the push rod and the fastener can be achieved, preventing separation or loosening of the push rod and fastener during the operation of the fastening assembly. When the fastening assembly needs to be operated, the push rod can be rotated, and the movement distance of the fastener along the first direction can be precisely controlled by utilizing the characteristics of the threaded connection. This ensures that the fastener can be accurately housed in or extend out of the receiving cavity, realizing the opening or closing of the fastening space. This threaded connection method is not only simple in structure and reliable in connection, but also easy to install and disassemble. When the fastening assembly needs to be repaired or replaced, simply rotate the push rod to separate it from the fastener, improving the convenience and efficiency of maintenance. At the same time, the threaded connection also has a certain self-locking function, which can maintain the relative position between the push rod and the fastener without external force, further enhancing the stability and reliability of the fastening assembly.

[0018] In some embodiments of this application, the fastener is provided with a first inclined surface, and the first hook is provided with a second inclined surface. The second inclined surface is configured to correspond to the first inclined surface to guide the first hook into the fastening space.

[0019] By setting a first inclined surface on the fastener and a second inclined surface on the first latch, with the second inclined surface corresponding to the first inclined surface, a guiding effect can be achieved during the insertion of the first hook into the fastening space. When the operator brings the first hook of the air duct assembly close to the fastening space, due to the corresponding setting of the two inclined surfaces, the second inclined surface of the first hook will slide along the first inclined surface of the fastener, thus entering the fastening space more smoothly and accurately. At the same time, it can also effectively push the fastener to move along the first direction. This design avoids jamming or collision during the insertion of the first hook, reduces resistance during installation, and further improves the efficiency and accuracy of installation. At the same time, the cooperation of the two inclined surfaces can also distribute the force on the first hook to a certain extent when it is inserted, reducing the risk of damage to the fastener and the first hook, extending the service life of the fastening assembly and the air duct assembly, and ensuring the stability and reliability of the overall refrigerator structure.

[0020] In some embodiments of this application, the air duct assembly includes: Air duct components; A duct panel, wherein the duct component is disposed on the duct panel, and when the duct panel is covered on the inner liner body, the duct component and the first inner wall surface form an airflow channel, and the airflow channel is connected to the storage chamber; The first hook is disposed on the air duct panel and is located on the outer periphery of the air duct component.

[0021] By incorporating air duct components and an air duct panel on the first inner wall, cold air can be guided to circulate within the storage compartment, thereby achieving uniform temperature control within the storage compartment. Furthermore, the air duct components and air duct panel not only optimize the refrigerator's cooling performance, but the air duct panel also enhances the neatness of the refrigerator's internal structure.

[0022] Furthermore, this design allows the first hook to easily engage with the fastening components on the inner liner body, ensuring a secure installation of the air duct assembly. Once the first hook is inserted into the fastening space, the fastening components lock tightly into place, preventing the air duct assembly from loosening or falling off during use. Simultaneously, because the first hook is located on the outer periphery of the air duct component, it does not interfere with its normal operation, ensuring unobstructed airflow. Moreover, this design facilitates the disassembly and replacement of the air duct assembly. When cleaning or repairing the air duct assembly, simply operate the fastening components to separate them from the first hook, easily removing the air duct assembly from the inner liner body, thus improving the convenience of maintenance and cleaning.

[0023] In some embodiments of this application, the air duct panel includes: Top edge; The lower edge and the upper edge are arranged opposite each other along the height direction of the box; Two side edges are arranged opposite each other along the width direction of the box body, and the upper edge, the lower edge and the two side edges are connected to enclose it; The first hook includes multiple hooks, and the upper edge and / or the side edge are provided with multiple first hooks.

[0024] By incorporating multiple first hooks on the upper and / or side edges of the air duct panel, the connection stability between the air duct assembly and the inner liner body is further enhanced. The evenly distributed first hooks distribute force, preventing connection failure due to excessive localized stress. When the air duct assembly is subjected to external forces, the multiple first hooks collectively bear the force, making the connection between the air duct assembly and the inner liner body more reliable, effectively preventing the air duct assembly from shaking or shifting, and ensuring the stable operation of the refrigerator's refrigeration system. Furthermore, this multiple hook design increases the tolerance for errors during air duct assembly installation; even if individual hooks experience slight deviations during installation, the others can still ensure the air duct assembly is accurately positioned, improving the success rate and efficiency of installation.

[0025] In some embodiments of this application, when the first hook is attached to the upper edge, the first direction is the height direction of the box body, and the second direction is the front-back direction of the box body; and / or, When the first hook is attached to the side edge, the first direction is the width direction of the box body, and the second direction is the front-back direction of the box body.

[0026] When the first hook located at the upper edge is engaged with the fastening component on the inner liner, the installation direction of the air duct component is the front-to-back direction of the housing. When the first hook extends into the fastening space along the front-to-back direction of the housing, the corresponding fastening component moves along the height direction of the housing to open the fastening space. When the first hook is fully inserted into the fastening space, the fastening component resets along the height direction of the housing and forms a tight fastening with the first hook, ensuring the stability and reliability of the air duct component installation.

[0027] When the first hook located on the side edge is engaged with the fastening component on the inner liner, the installation direction of the air duct component is the front-to-back direction of the housing. When the first hook extends into the fastening space along the front-to-back direction of the housing, the corresponding fastening component moves along the width direction of the housing to open the fastening space. When the first hook is fully inserted into the fastening space, the fastening component resets along the width direction of the housing and forms a tight fastening with the first hook, ensuring the stability and reliability of the air duct component installation.

[0028] Compared with the prior art, the beneficial effects of this application are: The refrigerator of this application forms a fastening space between the first inner wall surface of the inner liner and the fastening component. The fastening component can move relative to the first inner wall surface in a first direction to open the fastening space. Therefore, when the air duct component needs to be installed on the inner liner, the movement of the fastening component allows the first hook to extend into the fastening space in a second direction, and the fastening component can also engage with the first hook, thereby fixing the air duct component to the first inner wall surface. It is evident that the refrigerator of this application achieves a screwless connection between the air duct component and the inner liner, maintaining the integrity of the inner liner while avoiding the damage to the liner that may be caused by traditional clip-on fixing methods. Furthermore, during assembly, the operator only needs to align the first hook of the air duct component with the fastening component and push the fastening component to move in the first direction to open the fastening space. After the first hook extends, the fastening component is released to complete the fixing of the air duct component. This design not only simplifies the assembly process and reduces the use of tools but also improves assembly efficiency and effectively reduces assembly difficulty. Attached Figure Description

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] In this application, the terms "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0034] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0035] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0036] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts.

[0038] As a widely used refrigeration device in modern home appliances, the core refrigeration principle of a frost-free refrigerator is to use air as the refrigerant to achieve a cooling effect. The evaporator inside the refrigerator converts air into cold air. Subsequently, this cold air, driven by the internal fan, is evenly and precisely distributed to each compartment of the refrigerator through the air duct assembly, thereby effectively regulating and lowering the overall temperature of the refrigerator and ensuring that food is kept fresh for a long time in a suitable low-temperature environment.

[0039] In related technologies, to achieve a reliable connection between the refrigerator liner and the air duct assembly, a common method is to install clips on the air duct assembly and secure it inside the liner using these clips. During actual installation, the operator needs to apply considerable external force to forcefully push the clips on the air duct assembly into the liner. This process often requires the liner material to deform under stress to allow the clips to engage smoothly, thus achieving a stable connection between the liner and the air duct assembly.

[0040] However, this seemingly simple and direct fixing method has several drawbacks. On the one hand, it requires a large amount of external force, making it laborious and inefficient to operate. It also places high demands on the physical strength and skills of the operators, increasing the labor intensity and time cost in the production process. On the other hand, this violent installation method can easily cause irreversible damage to the inner liner, leading to cracks, deformation, or even rupture.

[0041] In view of this, the refrigerator disclosed in this application can achieve stable installation of the air duct components while effectively simplifying the assembly process, reducing the use of tools, significantly improving assembly efficiency, and effectively reducing assembly difficulty.

[0042] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0043] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of this application. The refrigerator 100 disclosed in this application can be, for example, a double-door refrigerator, a single-door refrigerator, a three-door refrigerator, or a French door refrigerator. Alternatively, it can be a French door refrigerator, i.e., the upper part is a double-door refrigerator compartment providing ample storage space for users, and the lower part is typically a drawer-type freezer compartment, making it easier to classify, store, and access frozen foods. The specific form is not limited in this embodiment of the application.

[0044] In some embodiments, the refrigerator 100 includes a cabinet 10 defining a storage compartment 20a for storing food. The storage compartment 20a may include a freezer compartment, a refrigerator compartment, or a variable temperature compartment, etc.

[0045] Understandably, the temperature of a refrigerator compartment is typically between 2°C and 8°C, which keeps food refrigerated. The temperature of a freezer compartment is typically between -14°C and -26°C, which keeps food frozen. The temperature of a variable-temperature compartment is generally adjustable between 5°C and -7°C, or it can be directly set to -18°C for use as a freezer.

[0046] It is understood that the distance from the bottom to the top of the box 10 is the height direction Z of the box 10. The box 10 also has a width direction Y and a front-to-back direction X. Specifically, the distance from one end of the box 10 to the other end is the width direction Y of the box 10. The front side of the box 10 is the side facing the user. The rear side of the box 10 is opposite to the front side, and the extension direction from the rear side to the front side is the front-to-back direction X of the box 10. Among the width direction Y, the front-to-back direction X, and the height direction Z of the box 10, every pair of directions is perpendicular. That is, the width direction Y of the box 10 is perpendicular to the front-to-back direction X, the width direction Y of the box 10 is perpendicular to the height direction Z, and the front-to-back direction X of the box 10 is perpendicular to the height direction Z. The box 10 forms a rectangular shape extending vertically, and its overall shape is rectangular.

[0047] Please see Figure 2 , Figure 2This is an exploded view of a refrigerator provided in an embodiment of this application. In some embodiments, the refrigerator 100 includes an inner liner 20 disposed in the body 10, the inner liner 20 forming a storage compartment 20a for storing items.

[0048] In some embodiments, the refrigerator 100 includes a door 30, which is movably connected to the cabinet 10 to open or close the storage compartment 20a to prevent cold air from leaking out of the storage compartment 20a.

[0049] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of a refrigerator (excluding the door and cabinet) provided in an embodiment of this application. In some embodiments, the refrigerator 100 includes an air duct assembly 40, which is disposed in the storage compartment 20a. The air duct assembly 40 is used to deliver cold air into the storage compartment 20a to maintain the required low temperature environment in the storage compartment 20a.

[0050] In some embodiments, the inner liner 20 includes an inner liner body 21, the inner liner body 21 includes a first inner wall surface 211, the first inner wall surface 211 is a side along the front-rear direction X of the box body 10, that is, the first inner wall surface 211 is the rear wall surface of the inner liner 20 along the front-rear direction X of the box body 10.

[0051] In some embodiments, the inner liner body 21 further includes a second inner wall surface 212 and a third inner wall surface 213 that are opposite each other along the width direction Y of the box body 10, and the second inner wall surface 212, the first inner wall surface 211 and the third inner wall surface 213 enclose the storage chamber 20a.

[0052] Please see Figures 4 to 6 , Figure 4 This is an exploded view of a refrigerator (door and cabinet omitted) provided in an embodiment of this application. Figure 5 This is a front view of a refrigerator (door and cabinet omitted) provided in an embodiment of this application. Figure 6 for Figure 5 A cross-sectional view of AA. In some embodiments, the duct assembly 40 is provided with a first latch 41 (see AA). Figure 7 The inner liner body 21 also includes a fastening assembly 22, which is movably disposed on the first inner wall surface 211 and located in the storage chamber 20a, forming a fastening space 21a between the fastening assembly 22 and the first inner wall surface 211. The fastening assembly 22 can move relative to the first inner wall surface 211 along a first direction F1 to open the fastening space 21a, allowing the first hook 41 to extend into the fastening space 21a along a second direction F2. The fastening assembly 22 can also engage with the first hook 41 to fix the air duct assembly 40 to the first inner wall surface 211. The first direction F1 and the second direction F2 intersect.

[0053] The refrigerator 100 of this application forms a fastening space 21a between the first inner wall surface 211 of the inner liner body 21 and the fastening component 22. The fastening component 22 can move relative to the first inner wall surface 211 in a first direction F1 to open the fastening space 21a. Therefore, when it is necessary to install the air duct component 40 onto the inner liner 20, the movement of the fastening component 22 allows the first hook 41 to extend into the fastening space 21a in a second direction F2, and the fastening component 22 can also engage with the first hook 41, thereby fixing the air duct component 40 to the first inner wall surface 211. It can be seen that the refrigerator 100 of this application can achieve a screwless connection between the air duct component 40 and the inner liner 20, maintaining the integrity of the inner liner 20 while avoiding the damage to the liner that may be caused by traditional claw fixing methods. Furthermore, in the refrigerator 100 of this application, during assembly, the operator only needs to align the first hook 41 of the air duct assembly 40 with the fastening assembly 22 and push the fastening assembly 22 along the first direction F1 to open the fastening space 21a. Once the first hook 41 is inserted, the fastening assembly 22 is released, thus completing the fixation of the air duct assembly 40. This design not only simplifies the assembly process and reduces the use of tools, but also improves assembly efficiency and effectively reduces assembly difficulty.

[0054] Please see Figure 7 , Figure 7 This is an exploded view of the air duct assembly provided in an embodiment of this application. In some embodiments, the air duct assembly 40 includes an air duct component 42 and an air duct panel 43. The air duct component 42 is disposed on the air duct panel 43. When the air duct panel 43 covers the inner liner body 21, the air duct component 42 and the first inner wall surface 211 form an airflow channel 42a, which communicates with the storage compartment 20a. By providing the air duct component 42 and the air duct panel 43 on the first inner wall surface 211, cold air can be guided to circulate within the storage compartment 20a, thereby achieving uniform temperature control within the storage compartment 20a. Furthermore, the arrangement of the air duct component 42 and the air duct panel 43 not only optimizes the cooling effect of the refrigerator 100, but also improves the neatness of the internal structure of the refrigerator 100.

[0055] It is understood that the connection between the air duct component 42 and the air duct panel 43 can be a snap-fit ​​connection, a screw connection, or an adhesive connection, etc., and this application embodiment does not limit this.

[0056] In some embodiments, the first hook 41 is disposed on the air duct panel 43 and is located on the outer periphery of the air duct component 42. This design allows the first hook 41 to easily engage with the fastening component 22 on the inner liner body 21, achieving a secure installation of the air duct component 40. When the first hook 41 extends into the fastening space 21a, the fastening component 22 can tightly engage with the first hook 41, preventing the air duct component 40 from loosening or falling off during use. Simultaneously, since the first hook 41 is located on the outer periphery of the air duct component 42, it does not affect the normal operation of the air duct component 42, ensuring unobstructed airflow through the airflow channel 42a. Furthermore, this design facilitates the disassembly and replacement of the air duct component 40. When cleaning or repairing the air duct component 40 is required, simply operate the fastening component 22 to separate it from the first hook 41, and the air duct component 40 can be easily removed from the inner liner body 21, improving the convenience of maintenance and cleaning.

[0057] See again Figure 7 In some embodiments, the air duct panel 43 includes an upper edge 431 and a lower edge 432 arranged opposite each other along the height direction Z of the cabinet 10, and two side edges 433 arranged opposite each other along the width direction Y of the cabinet 10. The upper edge 431, the lower edge 432, and the two side edges 433 are connected and enclosed. Multiple first hooks 41 are provided on the upper edge 431 and / or the side edges 433. By providing multiple first hooks 41 on the upper edge 431 and / or the side edges 433 of the air duct panel 43, the connection stability between the air duct assembly 40 and the inner liner body 21 can be further enhanced. The multiple first hooks 41 are evenly distributed, which can disperse the force and avoid connection failure due to excessive local force. When the air duct assembly 40 is subjected to external force, the multiple first hooks 41 can jointly bear the force, making the connection between the air duct assembly 40 and the inner liner body 21 more reliable, effectively preventing the air duct assembly 40 from shaking or shifting, and ensuring the stable operation of the refrigerator 100's refrigeration system. Moreover, this multi-hook design increases the fault tolerance of the air duct assembly 40 installation. Even if some hooks deviate slightly during installation, the other hooks can still ensure that the air duct assembly 40 is accurately positioned, improving the success rate and efficiency of installation.

[0058] In some embodiments, when the first hook 41 is located at the upper edge 431, the first direction F1 is the height direction Z of the housing 10, and the second direction F2 is the front-rear direction X of the housing 10. When the first hook 41 located at the upper edge 431 is engaged with the fastening component 22 on the inner liner 20, the installation direction of the air duct assembly 40 is the front-rear direction X of the housing 10. When the first hook 41 extends into the fastening space 21a along the front-rear direction X of the housing 10, the corresponding fastening component 22 moves along the height direction Z of the housing 10 to open the fastening space 21a. When the first hook 41 is fully extended into the fastening space 21a, the fastening component 22 resets along the height direction Z of the housing 10 and forms a tight fastening with the first hook 41, ensuring the stability and reliability of the air duct assembly 40 installation.

[0059] In some embodiments, when the first hook 41 is located at the side edge 433, the first direction F1 is the width direction Y of the housing 10, and the second direction F2 is the front-rear direction X of the housing 10. When the first hook 41 located at the side edge 433 is engaged with the fastening component 22 on the inner liner 20, the installation direction of the air duct assembly 40 is the front-rear direction X of the housing 10. When the first hook 41 extends into the fastening space 21a along the front-rear direction X of the housing 10, the corresponding fastening component 22 moves along the width direction Y of the housing 10 to open the fastening space 21a. When the first hook 41 is fully extended into the fastening space 21a, the fastening component 22 resets along the width direction Y of the housing 10 and forms a tight fastening with the first hook 41, ensuring the stability and reliability of the air duct assembly 40 installation.

[0060] The specific structure of the fastening component 22 will be described in detail below.

[0061] Please refer to the following: Figures 8 to 10 , Figure 8 This is a front view of the door frame provided in an embodiment of this application. Figure 9 for Figure 8 BB's cross-sectional view Figure 10This is an exploded view of the fastening assembly provided in an embodiment of this application. In some embodiments, the fastening assembly 22 includes a fastener 221 and a reset member 222. The fastener 221 is movably disposed on a first inner wall surface 211, forming a fastening space 21a between the fastener and the first inner wall surface 211. One end of the reset member 222 is connected to the first inner wall surface 211, and the other end of the reset member 222 is connected to the fastener 221. The reset member 222 is configured to provide a reset force to the fastener 221 to shield the fastening space 21a. By forming the fastening space 21a between the fastener 221 and the first inner wall surface 211, and by connecting the reset member 222 to the first inner wall surface 211 and the fastener 221, the fastener 222 provides a reset force to the fastener 221 to shield the fastening space 21a. This allows the fastener 221 to maintain the fastening space 21a in a shielded state in its free state, preventing the entry of foreign objects. When the air duct assembly 40 needs to be installed, an external force F1 along the first direction is applied to the fastener 221. The fastener 221 will then move against the resetting force of the reset member 222, thereby opening the fastening space 21a. At this time, the first hook 41 can smoothly extend into the fastening space 21a. After the first hook 41 is fully extended, the fastener 221 is released. The fastener 221 is reset under the resetting force of the reset member 222, re-covering the fastening space 21a and forming a tight fastening with the first hook 41, ensuring that the air duct assembly 40 is securely installed on the inner liner body 21. This design is not only simple in structure and easy to operate, but also effectively improves the stability and reliability of the connection between the air duct assembly 40 and the inner liner body 21.

[0062] It is understood that the reset of the fastening assembly 22 along the first direction F1 can be manual or automatic via the reset element 222, and this embodiment does not limit this. The following description uses the automatic reset of the fastening assembly 22 via a spring or reed plate as an example.

[0063] In some embodiments, the fastener 221 includes a fixing block 2211 and a fastening member 2212. The fixing block 2211 is disposed on the first inner wall surface 211 and has a receiving cavity 2211b. The fastening member 2212 is configured to be housed in the receiving cavity 2211b to open the fastening space 21a, and the fastening member 2212 is configured to extend out of the receiving cavity 2211b to cover the fastening space 21a. The fixing block 2211 serves as the basic support portion of the fastener 221 and is securely mounted on the first inner wall surface 211, providing a reliable mounting base for the entire fastening assembly 22. Meanwhile, the receiving cavity 2211b provides space for the housing and extension of the fastening member 2212. When the air duct assembly 40 needs to be installed, the fastening member 2212 is housed in the receiving cavity 2211b. At this time, the fastening space 21a is open, and the first hook 41 can be smoothly inserted. After the first hook 41 is inserted into place, the fastening member 2212 extends out of the receiving cavity 2211b, covers the fastening space 21a, and closely cooperates with the first hook 41 to achieve a stable installation of the air duct assembly 40.

[0064] See again Figure 9 In some embodiments, the fixing block 2211 is provided with a first through hole 2211a, and the fastening assembly 22 further includes a push rod 223. One end of the push rod 223 is connected to the fastening member 2212, and the other end of the push rod 223 is movably inserted through the first through hole 2211a. The push rod 223 is configured to drive the fastening member 2212 to move along the first direction F1 under the action of the reset member 222, so that the fastening member 2212 covers the fastening space 21a.

[0065] When the fastening space 21a needs to be opened, an external force F1 is applied to the push rod 223 in the first direction. The push rod 223 drives the fastening member 2212 to overcome the resetting force of the reset member 222 and move into the receiving cavity 2211b, thereby opening the fastening space 21a and facilitating the insertion of the first hook 41. After the first hook 41 is inserted into place, the push rod 223 is released. The reset member 222 drives the fastening member 2212 to move in the opposite direction F1 through the push rod 223, causing the fastening member 2212 to extend out of the receiving cavity 2211b, cover the fastening space 21a, and tightly fasten with the first hook 41, ensuring the stable installation of the air duct assembly 40. By setting the push rod 223 to drive the fastening member 2212 in the first through hole 2211a, the convenience and reliability of the operation of the fastening assembly 22 are further improved, while ensuring the stability and accuracy of the movement of the fastening member 2212, effectively avoiding connection failure caused by the movement deviation of the fastening member 2212.

[0066] In some embodiments, a stop block 2231 is provided at the end of the push rod 223 away from the fastener 221. The stop block 2231 is configured to abut against the fixing block 2211 when the fastener 221 closes the fastening space 21a to limit the displacement of the fastener 221 along the first direction F1. By providing a stop block 2231 at the end of the push rod 223 away from the fastener 221, when the fastener 221 closes the fastening space 21a under the reset action of the reset member 222, the stop block 2231 abuts against the fixing block 2211 to allow the fastener 221 to extend out of the receiving cavity 2211b by a distance of F1 along the first direction. This prevents the fastener 221 from falling out of the receiving cavity 2211b due to excessive reset, ensuring that the fastener 221 can be accurately reset to the position that covers the fastening space 21a and form a tight and reliable fastening with the first hook 41. This further improves the stability and reliability of the connection between the air duct assembly 40 and the inner liner body 21.

[0067] See again Figure 9 In some embodiments, the first inner wall surface 211 is formed with a groove 2111, and the fixing block 2211 is disposed in the groove 2111 and forms a distance between it and the bottom surface 2111a of the groove 2111, so that the first through hole 2211a and the bottom surface 2111a are spaced apart along the first direction F1, so as to provide the push rod 223 with displacement space along the first direction F1. By forming a groove 2111 on the first inner wall surface 211 and placing the fixing block 2211 in the groove 2111 and maintaining a certain distance between it and the bottom surface 2111a, displacement space along the first direction F1 can be provided for the push rod 223. When installing the air duct assembly 40, when an external force is applied to the push rod 223, the push rod 223 drives the fastening member 2212 to move to open the fastening space 21a. During this process, the push rod 223 can move smoothly within this displacement space without being obstructed by the first inner wall surface 211 or other structures, ensuring that the fastening assembly 22 can function normally and allowing the first hook 41 to smoothly extend into the fastening space 21a. At the same time, this design also makes reasonable use of the space of the first inner wall surface 211, making the structure of the entire fastening assembly 22 more compact and not occupying too much effective space in the storage compartment 20a, which is conducive to the optimized layout of the internal space of the refrigerator 100. Moreover, the groove 2111 plays a certain positioning and limiting role for the fixing block 2211, making the installation of the fixing block 2211 on the first inner wall surface 211 more stable and less prone to shaking or displacement, thereby ensuring the overall stability and reliability of the fastening assembly 22, further improving the stability of the connection between the air duct assembly 40 and the inner liner body 21, and ensuring the stable operation of the refrigerator 100's refrigeration system.

[0068] In some embodiments, the fastener 221 has a threaded hole (not shown), and the outer circumferential surface of the push rod 223 has an external thread (not shown), which is threadedly connected to the threaded hole. By setting the threaded hole of the fastener 221 to be threadedly connected to the external thread of the push rod 223, a stable connection between the push rod 223 and the fastener 221 can be achieved, preventing the push rod 223 from separating from the fastener 221 or loosening during the operation of the fastening assembly 22. When it is necessary to operate the fastening assembly 22, by rotating the push rod 223, the movement distance of the fastener 2212 along the first direction F1 can be precisely controlled by utilizing the characteristics of the threaded connection, ensuring that the fastener 2212 can be accurately housed in or extend out of the receiving cavity 2211b, thereby opening or closing the fastening space 21a. This threaded connection method is not only simple in structure and reliable in connection, but also convenient for installation and disassembly. When it is necessary to repair or replace the fastening assembly 22, it is only necessary to rotate the push rod 223 to separate it from the fastener 221, which improves the convenience and efficiency of maintenance. Meanwhile, the threaded connection also has a certain self-locking function, which can keep the relative position between the push rod 223 and the fastener 221 unchanged when no external force is applied, further enhancing the stability and reliability of the fastening assembly 22.

[0069] In some embodiments, the fastener 221 is provided with a first inclined surface 221a, and the first hook 41 is provided with a second inclined surface 41a (see...). Figure 6 The second inclined surface 41a is configured to correspond to the first inclined surface 221a to guide the first hook 41 into the fastening space 21a. By setting the first inclined surface 221a on the fastener 221 and the second inclined surface 41a on the first buckle, with the second inclined surface 41a corresponding to the first inclined surface 221a, a guiding effect can be achieved as the first hook 41 extends into the fastening space 21a. When the operator brings the first hook 41 of the air duct assembly 40 close to the fastening space 21a, due to the corresponding setting of the two inclined surfaces, the second inclined surface 41a of the first hook 41 will slide along the first inclined surface 221a of the fastener 221, thus entering the fastening space 21a more smoothly and accurately, while also effectively pushing the fastener 221 to move along the first direction F1. This design avoids jamming or collision of the first hook 41 during insertion, reduces resistance during installation, and further improves the efficiency and accuracy of installation. At the same time, the cooperation of the two inclined surfaces can also disperse the force on the first hook 41 when it is inserted to a certain extent, reduce the risk of damage to the fastener 221 and the first hook 41, extend the service life of the fastening assembly 22 and the air duct assembly 40, and ensure the stability and reliability of the overall structure of the refrigerator 100.

[0070] Optionally, the fastener 221 can be a right-angled triangular block structure, and correspondingly, the first inclined surface 221a of the fastener 221 is the inclined surface in the right-angled triangular block structure; the first hook 41 can also be a right-angled triangular block structure, and correspondingly, the second inclined surface 41a of the first hook 41 is the inclined surface in the right-angled triangular block structure. When the first hook 41 extends in along the second direction F2, and the second inclined surface 41a is correspondingly set with the first inclined surface 221a, the second inclined surface 41a of the first hook 41 will... Sliding along the first inclined surface 221a of the fastener 221, the fastener 221 moves along the first direction F1 to open the fastening space 21a, and the first hook 41 enters the fastening space 21a. Then, the fastener 221 is reset along the first direction F1 under the action of the reset member 222. The right angle surface of the fastener 221 corresponds to the right angle surface of the first hook 41. In this way, the right angle surface of the fastener 221 can effectively restrict the first hook 41 within the fastening space 21a, thereby realizing the fastening connection between the fastener 221 and the first hook 41.
