[0069] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-11 A refrigerator 100 according to a first aspect embodiment of the present invention is described.

[0070] like Figure 1 and Figure 2 As shown, the refrigerator 100 according to an embodiment of the present invention includes a first storage compartment 1, a second storage compartment 2, and an air duct 3.

[0071] Specifically, the second storage room 2 and the first storage room 1 are along the first direction (e.g. Figure 1 The air duct 3 is arranged in a left-right direction as shown, and its two ends are connected to the first storage room 1 and the second storage room 2 respectively.

[0072] For example, in Figure 1 and Figure 2In the example, the two ends of the duct 3 are connected to the rear sides of the first storage chamber 1 and the second storage chamber 2, respectively. The first storage chamber 1 can be a refrigerator compartment for preserving food. The second storage chamber 2 can be a freezer compartment for freezing food, but is not limited to this. With this configuration, the cooling capacity of the second storage chamber 2 can be transferred to the first storage chamber 1 through the duct 3, facilitating cooling in the first storage chamber 1 and thus improving its cooling effect. It should be noted that the duct 3 also contains other components for connecting or closing it.

[0073] Combination Figure 1 and Figure 2 The refrigerator 100 also includes a first sealing element 4 and a second sealing element 5. The first sealing element 4 is located between one end face of the air duct 3 and the first storage compartment 1, and the first sealing element 4 is connected to one end face of the air duct 3 and / or the first storage compartment 1; and / or, the second sealing element 5 is located between the other end face of the air duct 3 and the second storage compartment 2, and the second sealing element 5 is connected to the other end face of the air duct 3 and / or the second storage compartment 2.

[0074] For example, the first seal 4 and the second seal 5 can be configured in the following ways: First, the first seal 4 is located between one end face of the duct 3 and the first storage chamber 1, and the first seal 4 is connected to one end face of the duct 3 and / or the first storage chamber 1. Second, the second seal 5 is located between the other end face of the duct 3 and the second storage chamber 2, and the second seal 5 is connected to the other end face of the duct 3 and / or the second storage chamber 2. Third, the first seal 4 is located between one end face of the duct 3 and the first storage chamber 1, and the first seal 4 is connected to one end face of the duct 3 and / or the first storage chamber 1. And, the second seal 5 is located between the other end face of the duct 3 and the second storage chamber 2, and the second seal 5 is connected to the other end face of the duct 3 and / or the second storage chamber 2.

[0075] The first sealing element 4 is connected to one end face of the air duct 3 facing the first storage chamber 1, or the first sealing element 4 is connected to the outer periphery of the first storage chamber 1. The second sealing element 5 is connected to the other end face of the air duct 3 facing the second storage chamber 2, or the second sealing element 5 is connected to the outer periphery of the second storage chamber 2.

[0076] This configuration strengthens the seal at the connection between one end of the duct 3 and the first storage compartment 1 through the first sealing element 4, preventing cold air leakage and condensation at the connection. Similarly, the second sealing element 5 strengthens the seal at the connection between the other end of the duct 3 and the second storage compartment 2, again preventing cold air leakage and condensation, thus allowing the refrigerator 100 to operate normally for extended periods. Furthermore, when installing the duct 3 to either the first storage compartment 1 or the second storage compartment 2, the first sealing element 4 and the second sealing element 5 can be directly installed with the duct 3, or they can be directly installed with the first storage compartment 1 and the second storage compartment 2 respectively. This reduces the difficulty of installing the first sealing element 4 and the second sealing element 5, thereby improving the installation efficiency and production efficiency of the refrigerator 100. Furthermore, the first sealing element 4 and the second sealing element 5 have simple structures. During installation, when one end of the air duct 3 mates with the first storage compartment 1, it compresses the first sealing element 4, filling and sealing the gap between the aforementioned end of the air duct 3 and the first storage compartment 1. When the other end of the air duct 4 mates with the second storage compartment 2, it compresses the second sealing element 5, filling and sealing the gap between the aforementioned other end of the air duct 3 and the second storage compartment 2. This improves the sealing effect at the connection points, allowing the connections between the air duct 3 and the first storage compartment 1 and the second storage compartment 2 to be sealed without the need for sealing. Compared to traditional technologies that use multiple strips of tape or multiple pieces of sponge, this simplifies the sealing steps during installation, thereby shortening the installation time and improving the production efficiency of the refrigerator 100.

[0077] According to the refrigerator 100 of this utility model, the sealing performance at the connection points between the two ends of the air duct 3 and the corresponding first storage compartment 1 and second storage compartment 2 is improved, preventing condensation at the connection points and allowing the refrigerator 100 to be used normally for a longer period of time. Furthermore, the installation steps of the first sealing element 4 and the second sealing element 5 are simplified, thereby improving the installation efficiency of the refrigerator 100. In addition, the sealing structure of the first sealing element 4 and the second sealing element 5 is simple and has a good sealing effect, simplifying the sealing operation steps during installation, shortening the installation time, and thus improving the production efficiency of the refrigerator 100.

[0078] Furthermore, the first sealing element 4 is bonded to one end face of the duct 3. And / or, the second sealing element 5 is bonded to the other end face of the duct 3. For example, the arrangement of the first sealing element 4 and the second sealing element 5 includes the following situations: First, the first sealing element 4 is bonded to one end face of the duct 3. Second, the second sealing element 5 is bonded to the other end face of the duct 3. Third, the first sealing element 4 is bonded to one end face of the duct 3, and the second sealing element 5 is bonded to the other end face of the duct 3 (e.g., Figure 2(As shown). With this configuration, the first seal 4 and the second seal 5 can move together with the air duct 3, which facilitates transportation and allows the two ends of the air duct 3 to be directly installed in the first storage compartment 1 and the second storage compartment 2, respectively. This reduces the installation difficulty of the first seal 4 and the second seal 5 and improves the installation efficiency of the refrigerator 100.

[0079] According to some embodiments of this utility model, the first sealing element 4 is an integral structural component. And / or, the second sealing element 5 is an integral structural component. For example, the arrangement of the first sealing element 4 and the second sealing element 5 includes the following situations: First, the first sealing element 4 is an integral structural component. Second, the second sealing element 5 is an integral structural component. Third, both the first sealing element 4 and the second sealing element 5 are integral structural components. This arrangement improves the structural strength of the first sealing element 4 and the second sealing element 5, and enhances their performance. Furthermore, compared to the conventional technology where multiple tapes are used to seal the left and right ends of the duct, the first sealing element 4 and the second sealing element 5 can be used in one step, avoiding multiple sealing steps, simplifying the sealing process, and improving installation efficiency. It should be noted that the first sealing element 4 and the second sealing element 5 can be sponge components, but are not limited to this.

[0080] According to some embodiments of this utility model, refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 The duct 3 includes a first outer shell 31 and a second outer shell 32.

[0081] Specifically, the two ends of the first outer shell 31 are detachably connected to the first storage compartment 1 and the second storage compartment 2, respectively. The second outer shell 32 is located on the side of the first outer shell 31 facing the center of the refrigerator 100. The second outer shell 32 and the first outer shell 31 together define an air duct 35, which communicates with the first storage compartment 1 and the second storage compartment 2, respectively. The two ends of the second outer shell 32 are detachably connected to the first storage compartment 1 and the second storage compartment 2, respectively.

[0082] For example, in Figure 1 and Figure 2 In this example, the right end of the first outer shell 31 is detachably connected to the outer wall of the first storage chamber 1, and the left end of the first outer shell 31 is detachably connected to the outer wall of the second storage chamber 2. The first outer shell 31 is located behind the second outer shell 32, and the first outer shell 31 and the second outer shell 32 are detachably connected. The right end of the second outer shell 32 is detachably connected to the outer wall of the first storage chamber 1, and the left end of the second outer shell 32 is detachably connected to the outer wall of the second storage chamber 2. Cooling energy can flow from the second storage chamber 2 to the first storage chamber 1 through the air duct 35.

[0083] With this configuration, the right end of the duct 3 is connected to the first storage compartment 1 via the first outer shell 31 and the second outer shell 32, respectively, and the left end of the duct 3 is connected to the second storage compartment 2 via the first outer shell 31 and the second outer shell 32, respectively. This strengthens the connection between the two ends of the duct 3 and the first and second storage compartments 1 and 2, preventing the duct 3 from detaching from either compartment and improving its stability, thereby enhancing the safety of the refrigerator 100. Furthermore, the detachable connection facilitates future maintenance of the refrigerator 100, reducing the difficulty of maintenance for staff and simplifying repairs. Additionally, the simple structure of the duct 3 makes it easy to manufacture, improving production efficiency. The ability to connect the first outer shell 31 and the second outer shell 32 at the same end further enhances the sealing, achieving a seal-free design. It should be noted that the first outer shell 31 and the second outer shell 32 can be connected via snap-fit ​​mechanisms, but this is not a limitation.

[0084] The first mating surface 33 is formed by one end face of the first outer shell 31 (the right end of the first outer shell 31 facing the first storage chamber 1) and one end face of the second outer shell 32 (the right end of the second outer shell 32 facing the first storage chamber 1). The first sealing element 4 is adhered to the first mating surface 33. The second mating surface 34 is formed by the other end face of the first outer shell 31 (the left end of the first outer shell 31 facing the second storage chamber 2) and the other end face of the second outer shell 32 (the left end of the second outer shell 32 facing the second storage chamber 2). The second sealing element 5 is adhered to the second mating surface 34. Thus, the first sealing element 4 can be connected to one end face of both the first outer shell 31 and the second outer shell 32 simultaneously, and the second sealing element 5 can be connected to the other end face of both the first outer shell 31 and the second outer shell 32 simultaneously, further strengthening the connection between the first outer shell 31 and the second outer shell 32 and improving the stability of the duct 3. Furthermore, it also strengthens the sealing at the connections between the first outer shell 31 and the second outer shell 32 and the first storage chamber 1 and the second storage chamber 2, respectively.

[0085] According to some embodiments of the present invention, a first buckle 321 is provided on one of the first storage chamber 1 and the second outer shell 32, and a mating groove 11 is formed on the other of the first storage chamber 1 and the second outer shell 32. The mating groove 11 is formed by recessing inward from the outer wall surface of the first storage chamber 1 or the side wall of the second outer shell 32, and the first buckle 321 is engaged in the mating groove 11.

[0086] For example, the arrangement of the first latch 321 and the mating groove 11 includes the following situations: First, the first latch 321 is formed on the first storage chamber 1, and the mating groove 11 is formed on the second outer shell 32. Second, the first latch 321 is formed on the second outer shell 32, and the mating groove 11 is formed on the first storage chamber 1 (e.g., Figure 3 and Figure 4 (As shown). The first buckle 321 engages in the mating groove 11 to detachably connect the right end of the second outer shell 32 to the first storage chamber 1.

[0087] This design reduces the difficulty of assembling and separating the second outer shell 32 from the first storage compartment 1, thereby improving the assembly efficiency of the second outer shell 32 and the first storage compartment 1, and also improving the installation efficiency of the air duct 3 and the first storage compartment 1. Furthermore, the structure of the first snap-fit ​​321 and the mating groove 11 is simple, and the assembly process of the first snap-fit ​​321 and the mating groove 11 is not affected by the thickness of the outer wall of the first storage compartment 1. This solves the problem of difficult snap-fitting caused by the different outer wall thicknesses of the first storage compartment 1 in different models of refrigerator 100, thus improving the versatility and performance of the air duct 3. In addition, the installation method of the first storage compartment 1 and the air duct 3 differs from the traditional snap-fit ​​structure. The first step of the air duct 3 installation adopts a "hanging" method, which allows for immediate positioning of the air duct 3 and simplifies the operation.

[0088] It should be noted that, along the width direction of the second outer shell 32, the second outer shell 32 is provided with a plurality of first buckles 321, and the first storage chamber 1 is provided with a plurality of mating grooves 11 at positions opposite to the plurality of first buckles 321. For example, there are two first buckles 321 and two mating grooves 11, with each first buckle 321 and mating groove 11 corresponding to the other. In the description of this utility model, "a plurality of" means two or more. However, it is not limited to this, and the number and arrangement of the first buckles 321 and the mating grooves 11 can be specifically set according to the actual use to meet actual needs.

[0089] According to some other embodiments of the present invention, refer to Figure 6 and Figure 7 A second buckle 322 is provided on one of the first storage chamber 1 and the second outer shell 32. The free end of the second buckle 322 has a buckle portion 323. An opening 12 is formed on the other of the first storage chamber 1 and the second outer shell 32. When the second buckle 322 is engaged in the opening 12, the buckle portion 323 abuts against the side wall of the other of the first storage chamber 1 and the second outer shell 32.

[0090] For example, the arrangement of the second latch 322 and the opening 12 includes the following situations: First, the second latch 322 is disposed on the first storage chamber 1, the opening 12 is formed on the second outer shell 32, and the latch portion 323 abuts against the side wall of the second outer shell 32. Second, the second latch 322 is disposed on the second outer shell 32, the opening 12 is formed on the first storage chamber 1, and the latch portion 323 abuts against the side wall of the first storage chamber 1 (such as...). Figure 7 (As shown). In Figure 6 and Figure 7In the example, the second latch 322 is formed on the side of the second outer shell 32 facing the first storage chamber 1 (i.e., the front side of the second outer shell 32). One end of the latch portion 323 is connected to the end of the second latch 322 away from the second outer shell 32 (i.e., the front end of the second latch 322). The latch portion 323 abuts against the front side of the outer wall of the first storage chamber 1. Wherein, after the second latch 322 and the latch portion 323 pass through the opening 12, the right end of the air duct 3 is pushed in the extending direction opposite to the latch portion 323, so that at least a part of the outer wall of the first storage chamber 1 slides between the second outer shell 32 and the latch portion 323.

[0091] This design limits the second outer shell 32 and the latch 323 against the side wall of the first storage compartment 1, preventing the second outer shell 32 of the duct 3 from detaching from the first storage compartment 1 and enhancing the connection stability between the duct 3 and the first storage compartment 1. Furthermore, the simple structure of the second latch 322, latch 323, and opening 12 facilitates the assembly of the duct 3 with the first storage compartment 1, thereby improving the installation efficiency of the refrigerator 100. In addition, the installation method of the first storage compartment 1 and the duct 3 differs from the traditional snap-fit ​​structure; the first step of duct 3 installation uses a sliding rail installation method, which allows for immediate positioning of the duct 3 and simplifies the operation. It should be noted that, along the width direction of the second outer shell 32, the second outer shell 32 is provided with a plurality of second latches 322 and a plurality of latching parts 323. The first storage chamber 1 has a plurality of openings 12 at positions opposite to the plurality of second latches 322. For example, there are two second latches 322, two latching parts 323, and two openings 12, with each second latch 322 and latching part 323 corresponding to one another, and each second latch 322 and opening 12 corresponding to one another. However, this is not a limitation; the number and arrangement of the second latches 322, latching parts 323, and openings 12 can be specifically set according to actual usage to meet actual needs.

[0092] Furthermore, referring to Figure 6 and Figure 7 When the second buckle 322 is provided on the end face of the second outer shell 32 near the first storage chamber 1, an opening 12 is formed on the rear side wall of the first storage chamber 1. One end of the buckle 323 is connected to the end of the second buckle 322 away from the second outer shell 32. The other end of the buckle 323 first bends and extends toward one side of the second outer shell 32, and then bends and extends toward the side away from the second outer shell 32.

[0093] For example, in Figure 6 and Figure 7In the schematic example, one end of the buckle 323 is connected to the front end of the second buckle 322, and the other end of the buckle 323 extends away from the second buckle 322. The distance between the other end of the buckle 323 and the second outer shell 32 is greater than the distance between the middle of the buckle 323 and the second outer shell 32. The middle of the buckle 323 abuts against the front side of the side wall of the first storage chamber 1, and the cross-sectional shape of the buckle 323 is approximately wavy. This arrangement facilitates the smooth sliding of the side wall of the first storage chamber 1 into the second outer shell 32 and the buckle 323, thereby improving the assembly efficiency of the second outer shell 32 and the first storage chamber 1. In addition, it increases the strength of the connection between the second buckle 322 and the buckle 323, preventing the connection between the second buckle 322 and the buckle 323 from breaking after long-term use, thus ensuring a stable connection between the second outer shell 32 and the first storage chamber 1 for a long time.

[0094] According to some embodiments of this utility model, refer to Figure 3 and Figure 5 One of the first storage chamber 1 and the first outer shell 31 is provided with a first latch 13, and the other of the first storage chamber 1 and the first outer shell 31 is formed with a first through hole 311. The first latch 13 fits into the first through hole 311, and the free end of the first latch 13 abuts against the side wall of the other of the first storage chamber 1 and the first outer shell 31. For example, the arrangement of the first latch 13 and the first through hole 311 includes the following situations: First, the first storage chamber 1 is provided with a first latch 13, the first outer shell 31 is formed with a first through hole 311, and the free end of the first latch 13 abuts against the side wall of the first outer shell 31 (e.g., Figure 5 (As shown). Second, the first outer shell 31 is provided with a first claw 13, and the first storage chamber 1 is formed with a first perforation 311. The free end of the first claw 13 abuts against the side wall of the first storage chamber 1.

[0095] exist Figure 3 and Figure 5 In the example, the free end of the first claw 13 extends first away from the first storage chamber 1, and then extends from left to right. By pressing the right end of the air duct 3, the first claw 13 passes through the first perforation 311 and abuts against the rear surface of the first outer casing 31. With this configuration, the first perforation 311 limits the first claw 13 circumferentially, preventing the air duct 3 from swaying circumferentially (e.g., vertically or horizontally) along the first claw 13, thereby improving the connection stability between the air duct 3 and the first storage chamber 1. Furthermore, the free end of the first claw 13 fixes the right end of the first outer casing 31, preventing the first outer casing 31 from detaching from the first claw 13, improving the connection strength between the first outer casing 31 and the first storage chamber 1, and thus improving the connection strength between the air duct 3 and the first storage chamber 1. For example, Figure 1 and Figure 2As shown, along the width direction of the first outer shell 31, a plurality of first through holes 311 are provided at intervals on the first outer shell 31, and a plurality of first claws 13 are provided at intervals on the rear side wall of the first storage chamber 1. For example, there are two first through holes 311 and two first claws 13. The first through holes 311 and the first claws 13 correspond one-to-one, but are not limited thereto. The number and arrangement of the first through holes 311 and the first claws 13 can be specifically set according to the actual use situation to meet the actual needs.

[0096] According to some embodiments of this utility model, refer to Figure 8 and Figure 9 A second claw 14 is provided on the rear side wall of the first storage chamber 1. A groove 141 is formed on the side of the second claw 14 facing the first outer shell 31. The end of the first outer shell 31 facing the first storage chamber 1 is fitted into the groove 141, and the free end of the second claw 14 abuts against the side wall of the first outer shell 31.

[0097] For example, in Figure 8 and Figure 9 In the example, the free end of the second claw 14 extends first in a direction away from the first storage chamber 1, and then in a direction from right to left. The free end of the second claw 14 and the rear side wall of the first storage chamber 1 together define a slot 141, in which the right end of the first outer casing 31 engages. This configuration limits the end of the second claw 14 against the end of the first outer casing 31, preventing the first outer casing 31 from moving away from the first storage chamber 1 and thus preventing it from detaching from the first storage chamber 1, thereby improving the installation stability of the duct 3. For example, Figure 8 As shown, along the width direction of the first outer shell 31, a plurality of second claws 14 are provided at intervals on the rear side wall of the first storage chamber 1. For example, there are two second claws 14, but it is not limited to this. The number and arrangement of the second claws 14 can be specifically set according to the actual use situation to meet the actual needs.

[0098] According to some embodiments of this utility model, refer to Figure 8 and Figure 9 A limiting post 15 is provided on the rear side wall of the first storage chamber 1. The limiting post 15 and the second claw 14 are along the width direction of the first outer shell 31 (e.g., Figure 9 Arranged in the vertical direction as shown, the first outer shell 31 has a first limiting groove 312 formed at the end facing the first storage chamber 1, and the limiting post 15 is fitted in the first limiting groove 312.

[0099] For example, in Figure 8 and Figure 9In the example, the limiting post 15 is approximately cylindrical in shape, and the inner wall of the first limiting groove 312 is in contact with at least a portion of the outer circumferential surface of the limiting post 15. This configuration limits the first outer shell 31, preventing it from moving vertically and avoiding vertical movement of the first outer shell 31 after assembly with the first storage chamber 1, thus improving the installation stability of the first outer shell 31. Furthermore, in conjunction with the second claw 14, the first outer shell 31 can be limited from different directions, effectively improving its installation stability and facilitating the long-term normal use of the duct 3.

[0100] According to some embodiments of this utility model, refer to Figure 10 and Figure 11 A protrusion 21 is provided on the rear side wall of the second storage chamber 2, and a second through hole 313 is formed at the end of the first outer shell 31 facing the second storage chamber 2, with the protrusion 21 fitting into the second through hole 313. For example, in Figure 10 and Figure 11 In the example, the protrusion 21 protrudes along the direction away from the rear sidewall of the second storage chamber 2, and the protrusion 21 passes through the second perforation 313. This arrangement allows the protrusion 21 to engage with the second perforation 313, limiting the left end of the first outer shell 31 along the circumference of the protrusion 21. This prevents the first outer shell 31 and the second storage chamber 2 from wobbling along the circumference of the protrusion 21 after assembly, thereby improving the assembly stability of the first outer shell 31 and the second storage chamber 2. Furthermore, it facilitates the rapid positioning of the other end of the duct 3 with the second storage chamber 2, improving the assembly efficiency of the duct 3 and the second storage chamber 2. In addition, the protrusion 21 and the second perforation 313 have simple structures, are easy to process and assemble, thus improving the assembly efficiency of the duct 3 and the second storage chamber 2.

[0101] Optionally, refer to Figure 10 and Figure 11 Along the direction from the first storage chamber 1 towards the second storage chamber 2, the free end face of the protrusion 21 is inclined in a direction away from the second storage chamber 2. For example, in Figure 10 and Figure 11 In the example, the free end of the protrusion 21 extends backward in a left-to-right direction. With this configuration, the free end of the protrusion 21 is positioned relative to the second through hole 313, which facilitates the rapid passage of the protrusion 21 through the second through hole 313, thereby further improving the assembly efficiency of the first housing 31 and the second storage chamber 2, and further improving the assembly efficiency of the air duct 3 and the second storage chamber 2.

[0102] According to some embodiments of this utility model, refer to Figure 10 and Figure 11 The second storage compartment 2 has a limiting protrusion 22 on the side facing the first storage compartment 1, and the width direction of the second outer shell 32 (e.g., Figure 10A second limiting groove 324 is formed on one side (shown in the up-down direction), and a limiting protrusion 22 fits into the second limiting groove 324. For example, in Figure 10 and Figure 11 In the example, the limiting protrusion 22 is formed on the right side of the second storage chamber 2, and the second limiting groove 324 is formed on the lower side of the left end of the second outer shell 32. The inner wall of the second limiting groove 324 is roughly C-shaped. At least a portion of the upper end of the limiting protrusion 22 fits into the second limiting groove 324. With this configuration, the limiting protrusion 22 limits the second outer shell 32 through the second limiting groove 324, preventing the second outer shell 32 from detaching from the second storage chamber 2 in the front-to-back direction, thereby improving the assembly stability of the air duct 3 and the second storage chamber 2. In addition, the assembly status of the limiting protrusion 22 and the second limiting groove 324 can be used to determine whether the air duct 3 and the second storage chamber 2 are properly assembled, so that adjustments can be made during the assembly process to improve the assembly accuracy of the air duct 3 and the second storage chamber 2, and also achieve the effect of sealing-free assembly. The air duct 3 can be a plastic part. Since the volume of plastic parts is smaller than that of foam parts, the influence of the air duct 3 on the flowability of the foam material can be reduced, thereby improving the foaming quality and further reducing costs.

[0103] In some examples of this application, the installation process of the refrigerator 100 is roughly as follows:

[0104] First, the first outer shell 31 and the second outer shell 32 are assembled into a duct 3. The first sealing element 4 is bonded to the first mating surface 33, and the second sealing element 5 is bonded to the second mating surface 34.

[0105] Then, install the right end of the air duct 3 to the first storage chamber 1. The two first claws 13 and the two first through holes 311 are aligned in the front-to-back direction, and the two first buckles 321 and the two mating grooves 11 are aligned in the front-to-back direction. Then, press the right end of the air duct 3 forward, so that the free end of the first claw 13 abuts against the first outer shell 31, and the first buckle 321 engages in the mating groove 11. Alternatively, first pass the two second buckles 322 and the two latches 323 through the two openings 12, then push the air duct 3 upward to the appropriate position, and then press the right end of the first outer shell 31 forward, so that the right end of the first outer shell 31 engages in the slot 141 of the second claw 14, and the limiting post 15 engages in the first limiting groove 312. The right end of the air duct 3 is then installed in the first storage chamber 1. At this point, the position of the air duct 3 is determined.

[0106] Next, the staff, holding the second storage chamber 2, pushes the two protrusions 21 into the two second through holes 313 respectively, and checks whether the limiting protrusions 22 are properly embedded in the second limiting grooves 324. If so, the installation is complete. If not, the positions of the air duct 3 and the second storage chamber 2 need to be readjusted until the limiting protrusions 22 are embedded in the second limiting grooves 324.

[0107] After the above installation operation, there is no need for employees to remove tape to reseal the connection between the air duct 3 and the first storage compartment 1 and the second storage compartment 2. The air duct 3 is locked at its degree of freedom by the above-mentioned components of the first storage compartment 1 and the second storage compartment 2 (e.g., the first claw 13 and the first through hole 311, the first buckle 321 and the mating groove 11, the second buckle 322, the buckle part 323 and the opening 12, the second claw 14, the limiting post 15 and the first limiting groove 312, the protrusion 21 and the second through hole 313, the limiting protrusion 22 and the second limiting groove 324), forming a connection relationship that is not easy to loosen. This allows the pre-attached first sealing element 4 and the second sealing element 5 to be compressed and filled to the mating surfaces of the two ends of the air duct 3 with the first storage compartment 1 and the second storage compartment 2, respectively, achieving the purpose of sealing without sealing and also improving the problem of condensation on the rear side of the refrigerator 100.

[0108] According to a second aspect embodiment of the refrigerator 100 of the present utility model, referring to... Figure 1 It includes a first storage room 1, a second storage room 2, and an air duct 3, with the second storage room 2 and the first storage room 1 arranged along a first direction. The two ends of the air duct 3 are connected to the first storage room 1 and the second storage room 2, respectively.

[0109] For example, in Figure 1 In the example, the two ends of the duct 3 are connected to the rear sides of the first storage chamber 1 and the second storage chamber 2, respectively. The first storage chamber 1 can be a refrigerator compartment for preserving food. The second storage chamber 2 can be a freezer compartment for freezing food, but is not limited to this. With this configuration, the cooling capacity of the second storage chamber 2 can be transferred to the first storage chamber 1 through the duct 3, facilitating cooling in the first storage chamber 1 and thus improving its cooling effect. It should be noted that the duct 3 also contains other components for connecting or closing it.

[0110] Among them, combined Figures 3-11 One end of the air duct 3 is detachably connected to the first storage chamber 1 via the connecting structure 6. The second storage chamber 1 is provided with a protrusion 21. The other end of the air duct 3 is provided with a second perforation 313. The protrusion 21 fits into the second perforation 313.

[0111] For example, the right end of the duct 3 is detachably connected to the first storage chamber 1 via a connecting structure 6. The connecting structure 6 can be implemented in various ways. For example, such as... Figures 3-5As shown, the connecting structure 6 includes a first claw 13, a first through hole 311, a first buckle 321, and a mating groove 11. The first claw 13 is disposed on the rear side wall of the first storage chamber 1, and the first through hole 311 is formed on the rear side wall of the right end of the air duct 3. The free end of the first claw 13 passes through the first through hole 311 and abuts against the side wall of the air duct 3. The first buckle 321 is disposed on the front side wall of the right end of the air duct 3, and the mating groove 11 is formed on the side wall of the first storage chamber 1. The first buckle 321 is engaged in the mating groove 11. That is, through the engagement of the first claw 13 with the first through hole 311 and the engagement of the first buckle 321 with the mating groove 11, the right end of the air duct 3 is detachably connected to the first storage chamber 1.

[0112] Or, such as Figures 6-9 As shown, the connecting structure 6 includes a second latch 322, a latching part 323, an opening 12, a second latching claw 14, a limiting post 15, and a first limiting groove 312. The second latch 322 is disposed on the front side wall of the right end of the air duct 3. One end of the latching part 323 is connected to the end of the second latch 322 away from the air duct 3. The opening 12 is formed on the rear side wall of the first storage chamber 1. When the second latch 322 is engaged in the opening 12, the latching part 323 abuts against the side wall of the first storage chamber 1. The second latching claw 14 is formed on the rear side wall of the first storage chamber 1. A groove 141 is formed on the side of the second latching claw 14 facing the air duct 3. The right end of the air duct 3 is engaged in the groove 141. The limiting post 15 is formed on the rear side wall of the first storage chamber 1. The limiting post 15 and the second claw 14 are arranged at intervals along the width direction of the air duct 3. The first limiting groove 312 is formed at the end of the air duct 3 facing the first storage chamber 1. The limiting post 15 is fitted into the first limiting groove 1.

[0113] This design strengthens the connection between the right end of the duct 3 and the first storage compartment 1 through the connecting structure 6, preventing the duct 3 from detaching from the first storage compartment 1 and improving the stability of the duct 3. Furthermore, the cooperation between the protrusion 21 and the second through hole 313 facilitates quick positioning of the left end of the duct 3 with the second storage compartment 2, improving assembly efficiency. The protrusion 21 also limits the left end of the duct 3, preventing it from wobbling and further enhancing assembly stability, thus improving the performance of the refrigerator 100. Additionally, it facilitates quick and accurate positioning of the left end of the duct 3 with the second storage compartment 2.
