Detailed Implementation

[0035] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0036] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures). If the specific posture changes, the directional indications or positional relationships will also change accordingly.

[0037] Refrigerators are common household appliances. Users can store food and items in the refrigerator's cooling compartment to extend their shelf life. Typically, refrigerators have an air duct cover between the cooling compartment and the air duct. This cover allows cold air from the air duct to be drawn out from the air outlets into the cooling compartment, maintaining its cooling effect.

[0038] However, in related technologies, the refrigerator's liner and air duct cover are often connected and fixed with screws. This requires drilling numerous screw holes in both the liner and the cover, and then individually installing a large number of screws into the corresponding holes, resulting in low efficiency in disassembling and assembling the air duct cover. Furthermore, the screws between the air duct cover and the liner are very prone to loosening, causing the air duct cover to become misaligned relative to the liner, leading to cold leakage and a poor user experience.

[0039] Based on this, this application provides a refrigerator that allows for convenient disassembly of the air duct cover and the refrigerator liner, while preventing the air duct cover from shifting relative to the refrigerator liner, thereby improving the user experience. It is understood that the refrigerator provided in this application includes household refrigerators, freezers, or commercial refrigerators, etc., and this application makes no limitation thereto.

[0040] The refrigerator provided in this application will now be described in conjunction with the accompanying drawings.

[0041] See Figures 1 to 4 This application provides a refrigerator 1, including a refrigerator liner 10, an air duct cover 20, and a connecting assembly 30. The refrigerator liner 10 has a cooling compartment 11. The air duct cover 20 is located inside the cooling compartment 11. The connecting assembly 30 includes a refrigerator liner connector 31 and a cover connector 32. The refrigerator liner connector 31 has a refrigerator liner fixing part 311 connected to the refrigerator liner 10 and at least partially located inside the cooling compartment 11, a snap-fit ​​part 312 connected to the refrigerator liner fixing part 311, and at least one limiting part connected to the refrigerator liner fixing part 311. The cover connector 32 has a cover plate fixing part 321 connected to the air duct cover 20, a snap-fit ​​mating part 322 connected to the cover plate fixing part 321, and at least one limiting mating part connected to the cover plate fixing part 321. The snap-fit ​​part 312 engages with the snap-fit ​​mating part 322, and at least one limiting part is connected to at least one limiting mating part in a one-to-one correspondence, so that the air duct cover 20 and the refrigerator liner 10 are detachably connected.

[0042] Understandably, the inner cabinet 10 serves as the basic frame of the refrigerator 1, supporting and installing components such as the air duct cover 20, shelves, storage drawers, evaporators, or fans. Meanwhile, the refrigeration compartment 11 formed by the inner cabinet 10 includes a refrigerator compartment, a freezer compartment, or a variable temperature compartment, facilitating the storage of food and other items by the user.

[0043] Understandably, the air duct cover 20 can be located inside the refrigeration chamber 11 and connected to the inner box 10, so as to cooperate with the inner box 10 to form an air duct that communicates with the refrigeration chamber 11, so that the refrigeration chamber 11 and the air duct can circulate and exchange gas, thereby maintaining the refrigeration effect of the refrigeration chamber 11.

[0044] Understandably, the connecting assembly 30 includes a box liner connector 31 connected to the box liner 10 and a cover plate connector 32 connected to the duct cover 20, so that the box liner 10 and the duct cover 20 can be detachably installed through the detachable connection between the box liner connector 31 and the cover plate connector 32. Specifically, the box liner connector 31 and the cover plate connector 32 can achieve detachable fastening between the duct cover 20 and the box liner 10 through the mutual snap-fit ​​of the snap-fit ​​part 312 and the snap-fit ​​mating part 322, and the box liner connector 31 and the cover plate connector 32 can also prevent the duct cover 20 from shifting relative to the box liner 10 through the one-to-one correspondence between at least one limiting part and at least one limiting mating part. At least one limiting part may be distributed around the snap-fit ​​part 312, and at least one limiting mating part may be distributed around the snap-fit ​​part 322, so that at least one limiting part and at least one limiting mating part can be limited in at least one direction among the up-down direction, left-right direction and front-back direction in the figure, thereby preventing the air duct cover 20 from shifting and avoiding cold leakage. It is understood that at least one limiting part and at least one limiting mating part can be connected one-to-one by a detachable connection method such as magnetic attraction, plug-in or threaded connection, and this application does not impose any limitation.

[0045] Understandably, the liner connector 31 can be connected to the liner 10 via the liner fixing part 311, and at least part of the liner fixing part 311 is located inside the refrigeration compartment 11 to facilitate connection with the cover connector 32. The liner fixing part 311 and the liner 10 can be fixed by welding, gluing, or integral molding. The liner fixing part 311 and the liner 10 can also be fixed by plug-in, threaded connection, or snap-fit, etc., and this application does not impose any limitations. Similarly, the cover connector 32 can be connected to the duct cover 20 via the cover fixing part 321. The cover fixing part 321 and the duct cover 20 can be fixed by welding, gluing, or integral molding. The cover fixing part 321 and the duct cover 20 can also be fixed by plug-in, threaded connection, or snap-fit, and this application does not impose any limitations.

[0046] Thus, the refrigerator 1 provided in this application has a connecting component 30 between the inner liner 10 and the air duct cover 20. The inner liner connector 31 is connected and fixed to the inner liner 10 through the inner liner fixing part 311, and the cover plate connector 32 is connected and fixed to the air duct cover 20 through the cover plate fixing part 321. Then, the inner liner connector 31 and the cover plate connector 32 are snapped and fixed by the snap-fit ​​part 312 and the snap-fit ​​mating part 322, so as to realize the detachable fastening between the air duct cover 20 and the inner liner 10 without the need to open screw holes and install screws one by one. This can realize the convenient disassembly and assembly between the air duct cover 20 and the inner liner 10 to improve the disassembly and assembly efficiency. Meanwhile, this application also utilizes a one-to-one correspondence between at least one limiting part and at least one limiting mating part to connect and limit the inner cabinet connector 31 and the cover plate connector 32 to each other, so as to achieve mutual limiting between the air duct cover plate 20 and the inner cabinet 10, thereby preventing the air duct cover plate 20 from shifting relative to the inner cabinet 10 to prevent cold leakage, and thus improving the user's experience of using the refrigerator 1.

[0047] See Figures 1 to 4 In one embodiment, the liner 10 has a top 12 and a bottom 13 arranged opposite to each other along the height direction of the liner 10. The liner 10 also has a back 14, a first side 15, and a second side 16 connected between the top 12 and the bottom 13, with the first side 15 and the second side 16 located on both sides of the back 14. The liner fixing part 311 of the liner connector 31 is connected to the back 14. The air duct cover 20 has a front side 21 and a back side 22 arranged opposite to each other along the thickness direction of the air duct cover 20, with the front side 21 facing the refrigeration compartment 11 and the back side 22 facing the back 14. The cover fixing part 321 of the cover connector 32 is connected to the back side 22.

[0048] Understandably, the height of the inner box 10 can be set vertically as shown in the figure, with the top 12 at the top and the bottom 13 at the bottom. The first side 15 and the second side 16 of the inner box 10 can be located on the left and right sides of the back 14 in the figure, with the first side 15 on the right and the second side 16 on the left. The thickness of the air duct cover 20 can be set longitudinally as shown in the figure, with the front side 21 facing forward and the back side 22 facing backward.

[0049] With this configuration, both the cover plate connector 32 and the box liner connector 31 can be concealed on the opposite side 22 of the air duct cover 20 to ensure a neat and aesthetically pleasing interior of the refrigeration compartment 11.

[0050] See Figures 1 to 4 In one embodiment, the snap-fit ​​portion 312 and the snap-fit ​​mating portion 322 are engaged in the direction from the top 12 to the bottom 13 of the box liner 10.

[0051] With this configuration, the engagement direction of the snap-fit ​​part 312 and the snap-fit ​​mating part 322 is set along the vertical direction in the figure, so that the engagement direction of the snap-fit ​​part 312 and the snap-fit ​​mating part 322 is the same as the direction of gravity of the duct cover 20. Thus, when the duct cover 20 is installed into the liner 10, the gravity of the duct cover 20 can act on the snap-fit ​​part 312 and the snap-fit ​​mating part 322, making the snap-fit ​​part 312 and the snap-fit ​​mating part 322 tightly engaged, thereby improving the reliability of the engagement connection and making the duct cover 20 less likely to fall off.

[0052] Understandably, if the snap-fit ​​part 312 and the snap-fit ​​mating part 322 are fastened together in the front-back direction (horizontal direction) as shown in the figure, the fastening direction is perpendicular to the gravity direction of the air duct cover 20. The gravity of the air duct cover 20 will easily cause the snap-fit ​​part 312 and the snap-fit ​​mating part 322 to separate, thereby making it easy for the fastening point between the air duct cover 20 and the box liner 10 to separate, reducing the installation reliability of the air duct cover 20.

[0053] See Figure 4 In one embodiment, at least one limiting portion and at least one limiting mating portion are used to limit the movement in the direction from the top 12 to the bottom 13 of the box liner 10 and / or in the direction perpendicular to the direction from the top 12 to the bottom 13 of the box liner 10.

[0054] Understandably, when at least one limiting part and at least one limiting mating part are limited in the direction from the top 12 to the bottom 13 of the box liner 10, the limiting direction of the connecting assembly 30 is the same as the fastening direction. At this time, at least one limiting part and at least one limiting mating part can be connected one-to-one to prevent the snap-fit ​​part 312 from disengaging from the snap-fit ​​part 322 in the vertical direction, thereby further improving the reliability of the fastening connection between the air duct cover 20 and the box liner 10.

[0055] When at least one limiting part and at least one limiting mating part are limited in a direction perpendicular to the top 12 to the bottom 13 of the box liner 10, the limiting direction of the connecting assembly 30 is perpendicular to the fastening direction. At this time, the fastening direction is set in the vertical direction and the limiting direction is set in the horizontal direction, which can prevent the snap-fit ​​part 312 and the snap-fit ​​mating part 322 from disengaging in the left-right direction and / or front-back direction, thereby preventing the air duct cover 20 from shifting relative to the box liner 10.

[0056] This configuration, through the snap-fit ​​connection between the snap-fit ​​part 312 and the snap-fit ​​mating part 322, and the one-to-one limiting connection between at least one limiting part and at least one limiting mating part, not only enables convenient disassembly of the air duct cover 20 and the box liner 10, but also forms a double connection and fixation between the air duct cover 20 and the box liner 10, thereby improving the connection stability between the air duct cover 20 and the box liner 10 and preventing the air duct cover 20 from falling off or shifting.

[0057] See Figures 5 to 8In one embodiment, to facilitate the engagement of the snap-fit ​​portion 312 and the snap-fit ​​mating portion 322, the snap-fit ​​mating portion 322 is provided with an elastic snap 3221 that protrudes in the direction from the top 12 to the bottom 13, and the snap-fit ​​portion 312 is provided with a groove 3121 that is recessed in the direction from the top 12 to the bottom 13, and the elastic snap 3221 engages with the groove 3121.

[0058] With this configuration, when the duct cover 20 and the housing liner 10 are installed, the slot 3121 faces upwards in the figure. The duct cover 20 can insert the elastic buckle 3221 into the slot 3121 along the direction of gravity, thus allowing the elastic buckle 3221 and the slot 3121 to be tightly engaged under the weight of the duct cover 20. Furthermore, the locking part 312 can also support the duct cover 20 to prevent it from shifting downwards relative to the housing liner 10, thereby avoiding displacement of the duct cover 20. When disassembling the duct cover 20 from the housing liner 10, simply move the elastic buckle 3221 upwards to disengage it from the slot 3121.

[0059] Of course, in other embodiments, the elastic buckle 3221 can also be provided in the snap-fit ​​portion 312, and the slot 3121 can be provided in the snap-fit ​​mating portion 322. As an example, the snap-fit ​​portion 312 is provided with an elastic buckle 3221 that protrudes in the direction from the bottom 13 to the top 12, and the snap-fit ​​mating portion 322 is provided with a slot 3121 that is recessed in the direction from the top 12 to the bottom 13.

[0060] With this configuration, when the duct cover 20 and the housing liner 10 are installed, the slot 3121 faces downwards in the diagram. The duct cover 20 can cover the slot 3121 over the elastic buckle 3221 along the direction of gravity, thus ensuring a tight fit between the slot 3121 and the elastic buckle 3221 under the weight of the duct cover 20. When disassembling the duct cover 20 and the housing liner 10, simply move the slot 3121 upwards to disengage it from the elastic buckle 3221.

[0061] See you later Figure 4 In one embodiment, at least one limiting part and at least one limiting mating part are inserted one-to-one in the direction from the front side 21 to the opposite side 22 of the air duct cover 20. With this arrangement, at least one limiting part and at least one limiting mating part can be inserted in the horizontal direction, and during the insertion process, the snap-fit ​​part 312 and the snap-fit ​​mating part 322 can gradually approach each other, so that the elastic buckle 3221 falls into the slot 3121 in the longitudinal direction (up and down direction) to achieve fastening.

[0062] See Figure 4In one embodiment, to improve the limiting effect, at least one limiting part is provided with a first limiting part 313 and a second limiting part 314 that are mutually spaced apart along the direction from the first side 15 to the second side 16, and a snap-fit ​​part 312 is located between the first limiting part 313 and the second limiting part 314. At least one limiting mating part is provided with a first limiting mating part 323 and a second limiting mating part 324 that are mutually spaced apart along the direction from the first side 15 to the second side 16, and a snap-fit ​​part 322 is located between the first limiting mating part 323 and the second limiting mating part 324. The first limiting part 313 is inserted into the first limiting mating part 323, and the second limiting part 314 is inserted into the second limiting mating part 324.

[0063] This configuration, where the first limiting part 313 engages with the first limiting mating part 323 and the second limiting part 314 engages with the second limiting mating part 324, creates engagement guides on both sides of the engaging part 312 and the engaging mating part 322. This ensures that the elastic latches 3221 of the engaging part 312 and the engaging mating part 322 can accurately fall into the slots 3121 for engagement. Simultaneously, the presence of limiting elements on both the left and right sides of the engaging part 312 and the engaging mating part 322 prevents the duct cover 20 from shifting in the left-right, up-down, or front-back directions after engagement with the liner 10. This ensures good installation accuracy for the duct cover 20 and prevents it from shifting relative to the liner 10.

[0064] See Figures 5 to 11 In one embodiment, the first limiting portion 313 includes a first limiting top plate 3131 and a first limiting bottom plate 3132 protruding from the box liner fixing portion 311 in a direction from the opposite side 22 to the front side 21, and the first limiting top plate 3131 and the first limiting bottom plate 3132 are spaced apart in a direction from the top 12 to the bottom 13. The first limiting mating portion 323 includes a first mating top plate 3231 and a first mating bottom plate 3232 protruding in a direction from the front side 21 to the opposite side 22, and the first mating bottom plate 3232 protrudes from the first mating top plate 3231 in a direction from the top 12 to the bottom 13. The first mating top plate 3231 is inserted between the first limiting top plate 3131 and the first limiting bottom plate 3132, and the first limiting bottom plate 3132 is inserted between the first mating top plate 3231 and the first mating bottom plate 3232.

[0065] With this configuration, the first limiting top plate 3131 and the first limiting bottom plate 3132 can be used to limit the first mating top plate 3231 in the vertical direction. The first mating top plate 3231 and the first mating bottom plate 3232 can be used to limit the first limiting bottom plate 3132 in the horizontal direction. Thus, the first limiting part 313 and the first limiting mating part 323 can cooperate to achieve limiting in at least two directions, ensuring that the elastic buckle 3221 can accurately fall into the slot 3121 and engage, and also preventing the air duct cover 20 from shifting relative to the box liner 10 by limiting in multiple directions.

[0066] Of course, in other embodiments, the first mating bottom plate 3232 may also protrude from the first mating top plate 3231 in the direction from the bottom 13 to the top 12, so that when the first mating top plate 3231 is inserted between the first limiting top plate 3131 and the first limiting bottom plate 3132, the first limiting top plate 3131 can be inserted between the first mating top plate 3231 and the first mating bottom plate 3232. This application does not limit this.

[0067] See Figures 5 to 11 In one embodiment, the second limiting portion 314 includes a second limiting top plate 3141 and a second limiting bottom plate 3142 protruding from the box liner fixing portion 311 in a direction from the opposite side 22 to the front side 21, and the second limiting top plate 3141 and the second limiting bottom plate 3142 are spaced apart in a direction from the top 12 to the bottom 13. The second limiting mating portion 324 includes a second mating top plate 3241 and a second mating bottom plate 3242 protruding in a direction from the front side 21 to the opposite side 22, and the second mating bottom plate 3242 protrudes from the second mating top plate 3241 in a direction from the top 12 to the bottom 13. The second mating top plate 3241 is inserted between the second limiting top plate 3141 and the second limiting bottom plate 3142, and the second limiting bottom plate 3142 is inserted between the second mating top plate 3241 and the second mating bottom plate 3242.

[0068] With this configuration, the second limiting top plate 3141 and the second limiting bottom plate 3142 can be used to limit the second mating top plate 3241 in the vertical direction. The second mating top plate 3241 and the second mating bottom plate 3242 can be used to limit the second limiting bottom plate 3142 in the horizontal direction. Thus, the second limiting part 314 and the second limiting mating part 324 can also cooperate to achieve limiting in at least two directions, ensuring that the elastic buckle 3221 can accurately fall into the slot 3121 for engagement, and also preventing the air duct cover 20 from shifting relative to the box liner 10 by limiting in multiple directions.

[0069] Of course, in other embodiments, the second mating bottom plate 3242 may also protrude from the second mating top plate 3241 in the direction from the bottom 13 to the top 12, so that when the second mating top plate 3241 is inserted between the second limiting top plate 3141 and the second limiting bottom plate 3142, the second limiting top plate 3141 can be inserted between the second mating top plate 3241 and the second mating bottom plate 3242. This application does not limit this.

[0070] See Figure 6 and Figure 11 In one embodiment, in the direction from top 12 to bottom 13, the first limiting top plate 3131 and the second limiting top plate 3141 are respectively disposed above the snap-fit ​​portion 312, and at least two of the first limiting bottom plate 3132, the second limiting bottom plate 3142 and the snap-fit ​​portion 312 are disposed flush with each other.

[0071] With this configuration, when the first mating top plate 3231 is inserted between the first limiting top plate 3131 and the first limiting bottom plate 3132, and the second mating top plate 3241 is inserted between the second limiting top plate 3141 and the second limiting bottom plate 3142, and the elastic buckle 3221 falls into the slot 3121 to engage, at least two of the first limiting bottom plate 3132, the second limiting bottom plate 3142, and the snap-fit ​​part 312 can simultaneously share the weight of the air duct cover 20, so that the box liner connector 31 can be evenly stressed, and the air duct cover 20 can be offset relative to the box liner 10 due to uneven stress on the box liner connector 31.

[0072] See Figure 6 In one embodiment, the box liner connector 31 is further provided with a support portion 315 connected to the box liner fixing portion 311. The support portion 315 is sequentially connected to the first limiting base plate 3132, the snap-fit ​​portion 312, and the second limiting base plate 3142.

[0073] It should be noted that when the duct cover 20 is connected to the liner 10, the cover connector 32 and the liner connector 31 bear the weight of the duct cover 20. At this time, the cover connector 32 and the liner connector 31 need to provide sufficient support to strongly support the duct cover 20, thereby preventing the duct cover 20 from shifting relative to the liner 10 and causing cold leakage.

[0074] With this configuration, the support part 315 can build a supporting bridge between the first limiting base plate 3132, the snap-fit ​​part 312, and the second limiting base plate 3142, so that the first limiting base plate 3132, the snap-fit ​​part 312, the second limiting base plate 3142 and the support part 315 form an integral whole, so as to jointly bear the weight of the air duct cover 20, strengthen the structural strength of the box liner connector 31, and thus provide stable and reliable support for the air duct cover 20.

[0075] See Figures 12 to 15In one embodiment, the liner 10 is further provided with an installation hole 17 communicating with the refrigeration chamber 11, and the liner fixing part 311 is further provided with a pre-embedded structure 3111 that penetrates the installation hole 17, so that the pre-embedded structure 3111 is located outside the refrigeration chamber 11.

[0076] It should be noted that a foam layer is formed between the liner 10 and the outer shell of the refrigerator 1 to insulate the cooling compartment 11. This application provides a pre-embedded structure 3111 protruding from the outside of the liner 10 on the liner fixing part 311, which allows the pre-embedded structure 3111 to be embedded in the foam layer, thereby increasing the connection strength between the liner fixing part 311 and the liner 10, and thus enabling the liner connector 31 to provide stable and reliable support for the air duct cover 20.

[0077] See Figure 13 In one embodiment, the embedded structure 3111 is provided with a plurality of protrusions and recesses. This arrangement increases the connection area between the embedded structure 3111 and the foam layer, thereby improving the connection reliability between the box liner fixing part 311 and the box liner 10.

[0078] See Figure 15 In one embodiment, to facilitate the separation of the air duct cover 20 from the box liner 10, the end of the slot 3121 facing the bottom 13 of the box liner 10 is provided with a disassembly hole 3122.

[0079] It should be noted that the disassembly hole 3122 can be used to insert a tool into the slot 3121. The tool can be used to lift the elastic buckle 3221 in the slot 3121, so that the elastic buckle 3221 is disengaged from the slot 3121, thereby separating the elastic buckle 3221 from the slot 3121, realizing the separation of the snap-fit ​​part 312 and the snap-fit ​​mating part 322, and thus realizing the separation between the air duct cover 20 and the box liner 10.

[0080] Understandably, tools include rod-shaped structures such as screwdrivers or pins, and this application does not impose any limitations.

[0081] See you later Figure 11 In one embodiment, the cover plate connector 32 is provided with at least one reinforcing rib 325 protruding in the direction from the bottom 13 to the top 12, and the at least one reinforcing rib 325 covers at least one of the snap-fit ​​portion 322 and the cover plate fixing portion 321.

[0082] Understandably, when the elastic buckle 3221 is repeatedly pushed up from the slot 3121, it will inevitably deform and tilt upwards. The reinforcing rib 325 can resist the tilting deformation of the elastic buckle 3221, thereby increasing the structural strength of the elastic buckle 3221 and preventing the elastic buckle 3221 from detaching from the slot 3121 after tilting up, which would cause the fastening to fail.

[0083] See you later Figure 11 In one embodiment, the first mating top plate 3231 and the second mating top plate 3241 are respectively spaced apart from the snap-fit ​​part 322. This arrangement can prevent the first mating top plate 3231 and the second mating top plate 3241 from obstructing the elastic buckle 3221 from being lifted, thereby ensuring smooth disassembly of the air duct cover 20 and the box liner 10.

[0084] This application does not elaborate on other structures of refrigerator 1.
