[0019] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-5 A refrigerator 100 according to an embodiment of the present utility model is described.

[0020] like Figures 1-4 As shown, the refrigerator 100 according to an embodiment of the present utility model includes: a cabinet 10, a door 20, an air duct assembly 30, and an air door component 40.

[0021] Specifically, the cabinet 10 includes a refrigerator compartment 11 and a freezer compartment 12, which are located along the height of the cabinet 10 (e.g., Figure 1 The arrangement is in the vertical direction, and the thickness direction of the box 10 is (e.g., in the vertical direction). Figure 1 An opening 13 is formed on one side (in the front-to-back direction). A door 20 is rotatably disposed at the opening 13. An air duct assembly 30 is disposed within the refrigerator compartment 11, and the air duct assembly 30 has an airflow channel 31 connecting the refrigerator compartment 11 and the freezer compartment 12. An air damper 40 is rotatably disposed within the airflow channel 31, and the air damper 40 divides the airflow channel 31 into a first sub-channel 311 and a second sub-channel 312. The first sub-channel 311 communicates with the freezer compartment 12, and the second sub-channel 312 communicates with the refrigerator compartment 11.

[0022] The damper component 40 has at least one mating groove 431 at its end, and the duct assembly 30 has a mounting hole 321. The inner wall of the mounting hole 321 is provided with at least one mating protrusion 50, which is adapted to mate with the mating groove 431 so that the damper component 40 can switch between an open state and a closed state. When the damper component 40 is rotated to the open state, the first sub-channel 311 and the second sub-channel 312 are connected. When the damper component 40 is rotated to the closed state, the first sub-channel 311 and the second sub-channel 312 are not connected.

[0023] For example, in Figure 1 In the example, the refrigerator compartment 11 is located below the freezer compartment 12. The air duct assembly 30 and the air damper 40 are located on the side of the refrigerator compartment 11 away from the door 20 in the thickness direction of the cabinet 10. Since there are no buttons in the refrigerator compartment that are easy to confuse users, the interference of different operation buttons is reduced. Users can locate the air damper 40 more quickly, reducing the probability of confusion and improving the convenience of use.

[0024] Furthermore, the damper component 40 extends along the width direction of the housing 10 (e.g., Figure 2 Extending in the left and right direction of the box body 10, the upper part of the damper 40 is the first sub-channel 311, and the lower part of the damper 40 is the second sub-channel 312. There can be 4 protrusions 50, but not limited to this, and there can be 30 grooves 431, but not limited to this.

[0025] When the damper 40 is in the open state, the mating protrusion 50 is positioned in the corresponding mating groove 431. At this time, the first sub-channel 311 and the second sub-channel 312 are connected, allowing cold air to flow from the freezer compartment 12 to the refrigerator compartment 11 for cooling. By rotating the damper 40, the mating protrusion 50 disengages from the mating groove 431. When the damper 40 is rotated to the closed state, the mating protrusion 50 engages in the other mating groove 431, disconnecting the first sub-channel 311 and the second sub-channel 312. On one hand, the rotation of the damper 40 directly controls the opening and closing of the first sub-channel 311 and the second sub-channel 312, thereby regulating the airflow distribution between the freezer compartment 12 and the refrigerator compartment 11 and ensuring the normal operation of the refrigerator 100's refrigeration system. On the other hand, the matching groove 431 and the protrusion ensure the stability of the state switching of the damper 40, allowing the damper 40 to be positioned in multiple positions, realizing the multi-level adjustment of the damper 40, thereby making the airflow distribution adjustment of the freezer compartment 12 and the refrigerator compartment 11 more flexible, and enabling the refrigerator 100 to meet more usage needs.

[0026] According to the embodiment of the present invention, the refrigerator 100, by placing the air duct assembly 30 in the refrigerator compartment 11 and providing mutually cooperating protrusions 50 and cooperating grooves 431, reduces interference from different operation buttons, allows users to locate the damper 40 more quickly, reduces the probability of confusion, improves the convenience of use, realizes the airflow distribution and adjustment of the freezer compartment 12 and the refrigerator compartment 11, ensures the normal operation of the refrigerator 100's refrigeration system, guarantees the stability of the damper 40's state switching, realizes the multi-level adjustment of the damper 40, and enables the refrigerator 100 to meet more usage needs.

[0027] According to some embodiments of this utility model, the rotation angle of the damper 40 is α, and α satisfies: 0︒≤α≤90︒.

[0028] like Figure 3 As shown, when α=0°, the damper 40 is in the closed state, and the width direction of the damper 40 is perpendicular to the flow direction of the airflow around the damper 40, which can intercept the airflow at the damper 40. At this time, the first sub-channel 311 and the second sub-channel 312 are disconnected, and the protrusion 50 is engaged in the corresponding mating groove 431. When 0°<α<90°, the damper 40 is partially open, and the width direction of the damper 40 is at a certain angle to the flow direction of the airflow around the damper 40. The first sub-channel 311 and the second sub-channel 312 are connected, and the airflow conduction area gradually increases with the increase of α. The amount of cold air entering the cold storage compartment 11 can be precisely adjusted according to the real-time temperature requirements of the cold storage compartment 11 to avoid sudden temperature rises and falls and maintain a stable cold storage environment. Figure 2 As shown, when α=90°, the damper 40 is in the open state, and the width direction of the damper 40 is parallel to the flow direction of the airflow around the damper 40. At this time, the airflow conduction area is the largest, and the cold air from the freezer compartment 12 can enter the refrigerator compartment 11 with the highest efficiency, which is suitable for scenarios where the refrigerator compartment 11 needs to be cooled quickly.

[0029] By setting the rotation angle α of the damper component 40 between 0° and 90°, the adjustment stroke of the damper component 40 is short, only a quarter of a circumference. Users do not need to apply significant force when turning the damper component 40, making it suitable for people with weaker hand strength. Furthermore, users can switch between the closed and open states without prolonged rotation, saving time and improving the ease of use of the refrigerator 100. In addition, the short adjustment stroke of the damper component 40 limits the frictional travel between the damper component 40 and the inner wall of the mounting hole 321, thereby reducing frictional wear between components and extending the service life of the damper component 40 and the air duct assembly 30.

[0030] In some optional embodiments, at least one elastic element 60 is provided in the mounting hole 321. The two ends of the elastic element 60 are connected to the inner wall of the mounting hole 321, and the elastic element 60 protrudes toward the center of the mounting hole 321. The protrusion 50 is provided on the side of the elastic element 60 adjacent to the center of the mounting hole 321.

[0031] For example, in Figure 3 and Figure 4In the example, the mounting hole 321 is a circular hole, and the axial direction of the mounting hole 321 is consistent with the length direction of the damper 40. The elastic element 60 is roughly arched, and the elastic element 60 and the inner wall of the mounting hole 321 together define a certain clearance space. When the damper 40 rotates, the elastic element 60 can deform towards the inner wall of the mounting hole 321, and the mating protrusion 50 moves towards the inner wall of the mounting hole 321 and smoothly disengages from the mating groove 431 at the end of the damper 40. When the damper 40 gradually rotates to the preset position, the elastic deformation of the elastic element 60 recovers, causing the mating protrusion 50 to gradually move away from the inner wall of the mounting hole 321 and engage in the corresponding mating groove 431. The elastic element 60 can ensure that the mating protrusion 50 and the mating groove 431 are tightly fitted.

[0032] The elastic element 60 ensures that when the damper 40 needs to be fixed, the mating protrusion 50 can be stably locked in the mating groove 431, and can also drive the mating protrusion 50 to move when the damper 40 rotates, thereby ensuring the reliability of the damper 40 adjustment and the performance of the refrigerator 100.

[0033] Furthermore, there are multiple mating protrusions 50 and multiple elastic elements 60, with each elastic element 60 corresponding one-to-one with a mating protrusion 50, and the multiple elastic elements 60 are spaced apart circumferentially along the mounting hole 321. The included angle between two adjacent mating protrusions 50 is β, and β satisfies: 0︒<β≤90︒.

[0034] like Figure 4 As shown, there are four mating protrusions 50 and four elastic elements 60, but not limited to these. The four elastic elements 60 are spaced apart circumferentially along the mounting hole 321. The side of each mating protrusion 50 away from the corresponding elastic element 60 is set towards the center of the mounting hole 321, and the included angle between two adjacent mating protrusions 50 is 90°.

[0035] On the one hand, multiple mating protrusions 50 are distributed circumferentially along the mounting hole 321, making the end of the damper 40 more evenly stressed. When the damper 40 rotates, the mating protrusions 50 contact the end of the damper 40. The multiple mating protrusions 50 can evenly transmit the force generated by the rotation of the damper 40 to the inner wall of the mounting hole 321 through the corresponding elastic element 60, avoiding local stress concentration and preventing deformation and damage to the mounting hole 321 or the end of the damper 40 due to uneven stress. This improves the reliability of the damper 40 and the air duct assembly 30 for long-term use. On the other hand, the evenly distributed mating protrusions 50 make the circumferential positioning of the damper 40 within the mounting hole 321 more accurate and stable. Regardless of whether the damper 40 is in an open, closed, or intermediate adjustment state, the mating of multiple mating protrusions 50 and mating grooves 431 can limit the circumferential movement of the damper 40, ensuring that the rotation angle of the damper 40 is more accurate. This, in turn, ensures precise control of the opening degree (cold capacity distribution) of the airflow channel 31, making the temperature regulation of the refrigerator compartment 11 and the freezer compartment 12 more stable and improving the performance of the refrigerator 100.

[0036] Furthermore, if β > 90°, the included angle between two adjacent mating protrusions 50 becomes too large, and the distribution of the mating protrusions 50 becomes too dispersed. This makes the end of the damper component 40 prone to localized stress concentration due to uneven force distribution. The mounting hole 321 or the end of the damper component 40 is also prone to deformation and damage due to uneven force distribution, resulting in poor long-term reliability of the damper component 40 and the duct assembly 30. Therefore, by setting the included angle β between two adjacent mating protrusions 50 between 0° and 90°, the long-term reliability of the damper component 40 and the duct assembly 30 is further improved.

[0037] According to some embodiments of this utility model, the distance between the two ends of the elastic member 60 gradually increases along the direction away from the center of the mounting hole 321, making the elastic member 60 approximately arched. Moreover, the gradual increase in the distance between the two ends of the elastic member 60 allows the elastic member 60 to have space for elastic deformation, thereby enabling the mating protrusion 50 to move when the damper member 40 rotates.

[0038] In addition, the structural design of the elastic element 60 allows it to compensate for certain manufacturing tolerances through its own elastic deformation. If there is a slight deviation in the end size of the mounting hole 321 or the damper 40, the elastic element 60 can adapt through its own deformation, ensuring the overall fit between the damper 40 and the air duct assembly 30, improving the refrigerator 100's compatibility with manufacturing tolerances, and reducing the manufacturing difficulty of the refrigerator 100.

[0039] According to some embodiments of the present invention, the damper component 40 includes: a damper body 41, a connecting shaft 42, and a gear part 43.

[0040] One end of the damper body 41 is rotatably connected to the air duct assembly 30, one end of the connecting shaft 42 is connected to the other end of the damper body 41, and the gear part 43 is provided at the other end of the connecting shaft 42. Multiple mating grooves 431 are formed on the gear part 43, and the gear part 43 is rotatably mated in the mounting hole 321.

[0041] like Figure 5 As shown, the damper body 41 is generally rectangular in shape, suitable for blocking or opening the airflow channel 31. One side of the damper body 41 along its length is rotatably connected to the air duct assembly 30, and the other side of the damper body 41 along its length is connected to the connecting shaft 42. The gear part 43 is located on the side of the connecting shaft 42 away from the damper body 41 along its length. The connecting shaft 42 has a through groove, which can reduce the overall weight of the damper part 40. The gear part 43 has multiple teeth, and there is a mating groove 431 between two adjacent teeth. The maximum outer diameter of the gear part 43 is smaller than the diameter of the mounting hole 321, or the maximum outer diameter of the gear part 43 is smaller than the minimum distance between two opposite mating protrusions 50 in the mounting hole 321.

[0042] When the damper 40 rotates, the gear 43 and the mating protrusion 50 engage. Each time the damper 40 rotates a certain angle, the mating protrusion 50 engages with the next mating groove 431, until the damper 40 rotates to the appropriate position, at which point the mating protrusion 50 is stably positioned in the corresponding mating groove 431. This allows the user to adjust the damper 40 to multiple positions, meeting a wider range of usage needs. Furthermore, the connecting shaft 42 provides a rotatable structural foundation for the gear 43 and stably transmits the force from the gear 43 to the damper body 41. Simultaneously, the relatively small overall size of the connecting shaft 42 reduces the overall weight of the damper 40 and lowers material costs.

[0043] According to some embodiments of the present invention, the refrigerator 100 further includes: a damper seat 70, which is disposed in the airflow channel 31, and an opening 71 is formed on the damper seat 70, which is opposite to the damper body 41.

[0044] The damper seat 70 has a mating hole 72, the connecting shaft 42 is mated in the mating hole 72, and a limiting protrusion 73 is provided in the mating hole 72. The limiting protrusion 73 is adapted to abut against the connecting shaft 42 to prevent the connecting shaft 42 from disengaging from the mating hole 72.

[0045] like Figure 3 and Figure 5 As shown, the damper seat 70 is a generally elongated frame structure, with an opening 71 formed in the height direction of the damper seat 70 (e.g., Figure 3On the side wall of the damper seat 70 (in the front-to-back direction), the shape of the opening 71 matches the shape of the damper body 41. A circular hole (not shown) is formed on the side wall of the damper seat 70 away from the mating hole 72 in the length direction. A rotating member (not shown) is provided at the corresponding position of the damper component 40, and the rotating member is provided in the circular hole. A limiting protrusion 73 is provided in the middle of the mating hole 72. The mating hole 72 has a notch 721 and a limiting part 722 on both sides of the limiting protrusion 73. The side of the notch 721 away from the limiting protrusion 73 extends to the end face of the damper seat 70. The limiting part 722 is approximately an arc-shaped groove, and the shape of the limiting part 722 matches the cross-sectional shape of the connecting shaft 42.

[0046] When the connecting shaft 42 passes through the mating hole 72 of the damper seat 70, the inner wall of the mating hole 72 (limiting part 722) fits tightly with the connecting shaft 42. The limiting protrusion 73 restricts the radial wobbling of the connecting shaft 42, preventing the damper body 41 from shifting radially during rotation, causing a gap between it and the airflow channel 31 of the duct assembly 30, or the connecting shaft 42 from coming out of the mating hole 72, thus ensuring the operational reliability of the damper assembly. Moreover, after the connecting shaft 42 passes through the mating hole 72 of the damper seat 70 and then mates with the mounting hole 321 of the duct assembly 30, the damper seat 70 provides partial support for the connecting shaft 42, preventing stress concentration at the mating point between the gear part 43 and the mounting hole 321, thus extending the overall service life of the damper assembly 40. Furthermore, the opening 71 of the damper seat 70 is opposite to the damper body 41. When the damper body 41 is rotated to the closed state (α=0°), the edge of the damper body 41 is aligned with the edge of the opening 71. When the damper body 41 is rotated to the open state (α=90°), the damper body 41 can avoid the opening 71. The airflow in the first sub-channel 311 enters the second sub-channel 312 from the opening 71. The opening 71 can guide the airflow, improving the airflow rate and efficiency.

[0047] According to some embodiments of this utility model, a knob 80 is provided at the mounting hole 321, and the knob 80 is connected to the gear part 43. For example... Figure 4 As shown, the gear part 43 is provided with a connector 432. The knob part 80 is connected to the gear part 43 through the connector 432. The connector 432 has a crescent-shaped rod structure. When the user rotates the knob part 80, the crescent-shaped connector 432 drives the gear part 43 to rotate synchronously, thereby driving the damper body 41 to rotate. The rotation angle of the knob is consistent with the rotation angle of the damper part 40, which makes it easy for the user to judge the opening and closing status of the damper part 40, improving the convenience of using the refrigerator 100. Moreover, the knob part 80 has a relatively simple structure and does not require a complex transmission mechanism, reducing the design and manufacturing cost of the refrigerator 100.

[0048] In some optional embodiments, the air duct assembly 30 includes a first air duct component 32, a second air duct component 33, and a first insulation component 34. Specifically, the first air duct component 32 has a first air outlet 322 formed thereon, and the second air duct component 33 is disposed in the thickness direction of the first air duct component 32 (e.g., ...). Figure 2 On one side of the first air duct component 32 (in the front-to-back direction), the first insulation component 34 is located in the height direction of the first air duct component 32 (e.g., in the front-to-back direction). Figure 2 On one side (up and down direction), the first insulation component 34, the first air duct component 32 and the second air duct component 33 together define the airflow channel 31, and a second air outlet 341 is formed on the first insulation component 34.

[0049] The refrigerated compartment 11 is connected to the first sub-channel 311 through the first air outlet 322, and the frozen compartment 12 is connected to the second sub-channel 312 through the second air outlet 341.

[0050] like Figures 1-3 As shown, the air duct assembly 30 is located on the side of the refrigerator compartment 11 away from the door 20 in the thickness direction of the cabinet 10. The second air duct component 33 is located adjacent to the inner wall of the cabinet 10. The first air duct component 32 is located on the side of the second air duct component 33 facing the door 20 in the thickness direction. The first air duct component 32 is divided into an extension portion 323 and a bending portion 324. The extension portion 323 extends along the height direction of the refrigerator compartment 11. The bending portion 324 is located on the side of the first air duct component 32 near the freezer compartment 12. The second air outlet 341 is located on the bending portion 324. The first insulation component 34 is located on the side of the first air duct component 32 adjacent to the freezer compartment 12 in the height direction, that is, the first insulation component 34 is located adjacent to the bending portion 324.

[0051] The airflow channel 31 is formed by the first air duct component 32, the second air duct component 33, and the first insulation component 34, ensuring that the cold air in the freezer compartment 12 can only flow along the airflow channel 31, thus improving the airflow rate and efficiency. Simultaneously, the first air outlet 322 on the first air duct component 32 can directionally deliver the airflow in the airflow channel 31 to different areas of the refrigerator compartment 11, and the second air outlet 341 on the first insulation component 34 can directionally deliver the airflow in the airflow channel 31 to different areas of the freezer compartment 12, thereby achieving precise airflow output and ensuring the operational reliability of the air duct assembly 30. Furthermore, the overall structure of the first air duct component 32, the second air duct component 33, and the first insulation component 34 is compact, avoiding the occupation of excessive storage space in the refrigerator compartment and improving the structural compactness of the refrigerator 100. In addition, the first insulation component 34 can retain the cold air within the airflow channel 31, ensuring that the cold air is effectively output to the preset location.

[0052] Specifically, the airflow channel 31 is provided with a second heat insulation component 35, on which a groove 351 and a third air outlet 352 are formed. The damper seat 70 is located in the groove 351, and the first sub-channel 311 is connected to the second air outlet 341 through the third air outlet 352.

[0053] like Figure 2 As shown, the shape of the second insulation component 35 is roughly the same as that of the first air duct component 32. The second insulation component 35 can prevent the leakage of cold air inside the airflow channel 31. At the same time, together with the first air duct component 32, the second air duct component 33 and the first insulation component 34, it can ensure the efficient transmission of airflow and improve the long-term reliability of the air duct assembly 30.

[0054] It should be noted that the first insulation component 34 and the second insulation component 35 can be made of foam material, and this application does not impose specific restrictions on this.
