[0085] Please refer to the attached Figure 7 In some embodiments, the air duct cover plate 3 may be provided with a first fastener 4. The first fastener 4 may be located on the rear side wall of the air duct cover plate 3. A slide groove 201 may be provided inside the box 2, and the first fastener 4 may be appropriately engaged with the slide groove 201, so that the air duct cover plate 3 and the inside of the box 2 can be connected together.

[0086] Please refer to the attached Figure 6 and attached Figure 7 In some embodiments, the slide 201 may include a first slide section 2011. The first slide section 2011 may be arranged toward the rear. The front end of the first slide section 2011 is provided with an opening 202 arranged toward the storage chamber opening, and the opening 202 may allow the first fastener 4 to pass through, so that the first fastener 4 may extend into the first slide section 2011 through the opening 202.

[0087] In some embodiments, the front end of the slide groove 201 is arranged toward the side where the air duct cover plate 3 is located, and the rear end of the slide groove 201 can be extended along the side where the rear side wall of the box 2 is located.

[0088] In some embodiments, the chute 201 may include a second chute section 2012. The second chute section 2012 may be connected to the first chute section 2011. The second chute section 2012 may extend from the rear end of the first chute section 2011 along the plane direction of the rear side wall inside the box 2.

[0089] In this way, the first locking member 4 can extend into the first slide slot section 2011 through the opening 202. Figure 7 and Figure 8 As shown, when the first latching member 4 is pushed, the first latching member 4 can be moved to the rear end of the first slide groove section 2011; Fig. 9 and Fig.10 As shown, the first fastener 4 is then slid along the second slide groove section 2012 in a direction away from the first slide groove section 2011, so that the first fastener 4 is turned from the direction of the first slide groove section 2011 to slide in the second slide groove section 2012, thereby enabling the first fastener 4 to be engaged in the second slide groove section 2012, thereby enabling the air duct cover 3 to be fixed on the rear side wall inside the box 2.

[0090] It should be noted that the first fastener 4 can leave the chute 201 by moving in the opposite direction. The first fastener 4 can slide along the second chute section 2012 toward the direction close to the rear end of the first chute section 2011, and slide through the rear end of the first chute section 2011 toward the front end of the first chute section 2011, and then the first fastener 4 can leave the first chute section 2011 through the opening 202. In this way, the clamping relationship between the first fastener 4 and the chute 201 can be released, so that the air duct cover plate 3 can be separated from the box 2, and the disassembly process of the box 2 and the air duct cover plate 3 is completed.

[0091] In some specific operation modes, when the operator installs the air duct cover 3 on the box 2, the operator pushes the first clamping member on the air duct cover 3 backward along the extension direction of the first slide groove section 2011 to make the first clamping member slide.

[0092] It should be noted that, during the installation and disassembly of the box 2 and the air duct cover 3, the refrigerator disclosed in the present application avoids using the hard-matching form of the clip-on structure of the box 2 and the air duct cover 3 in the related art, which not only makes the installation and disassembly of the two more convenient, simple and quick, but also the clip-on connection method is more flexible, and can also reduce the risk of damage and failure of the clip-on structure caused by hard squeezing and improper disassembly operation, thereby enhancing the durability of the connection structure between the box 2 and the air duct cover 3.

[0093] It should be noted that the configuration of the first fastener 4 and the slide groove 201 can be designed according to actual needs. In some other embodiments, the first fastener 4 can be provided inside the box 2, and the slide groove 201 can be provided on the rear side wall of the air duct cover 3. In this way, the box 2 and the air duct cover 3 can be connected together through the clamping between the first fastener 4 and the slide groove 201.

[0094] In some embodiments, the chute 201 may include a first chute section 2011. The first chute section 2011 may be arranged toward the rear. An opening 202 arranged away from the storage chamber opening is provided at the rear end of the first chute section 2011, and the opening 202 may allow the first fastener 4 to pass through, so that when the air duct cover plate 3 is installed inside the box 2, the first fastener 4 inside the box 2 may extend into the first chute section 2011 through the opening 202.

[0095] In some embodiments, the chute 201 may include a second chute section 2012. The first chute section 2011 may be connected to the second chute section 2012. The second chute section 2012 extends from the rear end of the first chute section 2011 along the plane direction of the front side wall of the air duct cover 3.

[0096] In this way, when the air duct cover plate 3 moves from the front of the box 2 to the rear side wall of the box 2, the first fastener 4 can extend into the first slide groove section 2011 through the opening 202. When the air duct cover plate 3 is continuously pushed, the first fastener 4 fixed on the box 2 moves to the front end of the first slide groove section 2011, and then slides along the second slide groove section 2012 in a direction away from the first slide groove section 2011, so that the first fastener 4 is engaged in the second slide groove section 2012, so that the air duct cover plate 3 can be fixed on the rear side wall inside the box 2. Moreover, the air duct cover plate 3 can be moved in the opposite direction, and the first fastener 4 can be separated from the first fastener 4 through the opening 202, so that the slide groove 201 of the air duct cover plate 3 and the first fastener 4 on the box 2 are separated, thereby completing the disassembly process of the box 2 and the air duct cover plate 3.

[0097] In some embodiments, the extension direction of the first chute section 2011 may be arranged at an angle to the extension direction of the second chute section 2012 .

[0098] like Figure 3 and Figure 8 As shown, in some embodiments, the first chute section 2011 can be arranged vertically with the second chute section 2012. On the one hand, the vertical arrangement of the first chute section 2011 and the second chute section 2012 means that when the air duct cover plate 3 is installed on the box 2, or removed from the box 2, the direction of the force driving the air duct cover plate 3 to move needs to be turned. In this way, when the air duct cover plate 3 or the box 2 is subjected to any external force, the vertical arrangement between the first chute section 2011 and the second chute section 2012 can provide a more stable support and fixing effect for the connection structure between the air duct cover plate 3 and the box 2, so that the position of the air duct cover plate 3 on the box 2 is not easy to deviate or shake.

[0099] In some embodiments, the first slide groove section 2011 can be extended toward the rear side wall inside the box 2 in a direction perpendicular to the front side wall of the air duct cover plate 3. In this way, the first fastener 4 provided on the air duct cover plate 3 can enter through the opening 202 at the front end of the first slide groove section 2011, and by pushing the air duct cover plate 3 backward, the first fastener 4 can slide to the rear end of the first slide groove section 2011.

[0100] In some embodiments, the second chute section 2012 can be extended from the rear end of the first chute section 2011 to the bottom of the rear side wall. In this way, when the first fastener 4 slides to the rear end of the first chute section 2011, a downward force can be applied to the air duct cover plate 3, so that the first fastener 4 turns to slide to the second chute section 2012, and then is engaged in the second chute section 2012, so that the air duct cover plate 3 is connected with the box 2.

[0101] In some embodiments, the first chute section 2011 can be extended toward the rear side wall inside the box 2 in a direction perpendicular to the front side wall of the air duct cover plate 3, and the second chute section 2012 can be extended from the rear end of the first chute section 2011 to the bottom of the rear side wall. When installing the air duct cover plate 3, push the air duct cover plate 3 toward the rear side wall inside the box 2, and when the first clip 4 slides to the rear end of the first chute section 2011, push the air duct cover plate 3 downward to complete the installation of the air duct cover plate 3 and the box 2; when removing the air duct cover plate 3, lift the air duct cover plate 3 upward and then pull it outward to complete the removal of the air duct cover plate 3 and the box 2. This simple structure for installation and removal makes the installation and removal of the two more convenient, simple and quick, and can also reduce the risk of damage and failure of the clamping structure caused by hard extrusion and improper removal operation, thereby enhancing the durability of the connection structure between the box 2 and the air duct cover plate 3.

[0102] It should be noted that, in some other embodiments, the second chute section 2012 can be extended from the rear end of the first chute section 2011 to the upper side of the rear wall. In this way, when the air duct cover plate 3 is installed backward so that the first fastener 4 moves to the rear end of the first chute section 2011, the first fastener 4 is engaged in the second chute section 2012 by lifting the air duct cover plate 3 upward.

[0103] In some embodiments, the first chute section 2011 may be in the shape of an elongated strip.

[0104] In some embodiments, the second chute section 2012 may be in the shape of an elongated strip.

[0105] like Figure 3 As shown, in some embodiments, the slide groove 201 formed by the first slide groove section 2011 and the second slide groove section 2012 is substantially L-shaped. The first slide groove section 2011 and the second slide groove section 2012 respectively form two straight sections of the L-shaped slide groove 201.

[0106] In some embodiments, the side wall provided at the connection between the rear end of the first slide groove section 2011 and the second slide groove section 2012 is configured to be arc-shaped, which can reduce the friction force of the first latch 4 during the sliding process along the slide groove 201 .

[0107] In some embodiments, the slide groove 201 may include two, and the two slide grooves 201 may be arranged on opposite sides of the rear side wall inside the box 2. The two slide grooves 201 may be arranged on the left and right sides or the upper and lower sides of the rear side wall inside the box 2.

[0108] It should be noted that, in some other embodiments, the distribution position of the slide groove 201 can be configured according to actual needs, and the two slide grooves 201 can also be arranged on the upper and lower sides of the rear side wall inside the box 2.

[0109] like Figure 5 As shown, in some embodiments, the rear side wall inside the box 2 may be provided with a mounting groove 203 that is recessed relative to the rear side wall toward the air duct cover plate 3 .

[0110] In some embodiments, the mounting groove 203 and the air duct cover plate 3 enclose a refrigeration air duct (not shown).

[0111] like Figure 5 As shown, in some embodiments, the first chute section 2011 and the second chute section 2012 are recessed and formed on the side wall of the mounting groove 203. By arranging the first chute section 2011 and the second chute section 2012 on the side wall of the mounting groove 203, the first fastener 4 on the air duct cover plate 3 can be snapped onto the side wall of the mounting groove 203, which is conducive to fully utilizing the space inside the box 2, making the structure of the entire refrigeration device more compact and suitable for refrigerators of various sizes.

[0112] In some embodiments, the two opposite side walls of the installation groove 203 are respectively provided with a slide groove 201. By providing a slide groove 201 on each of the two opposite side walls of the installation groove 203, the air duct cover plate 3 can be engaged with the slide grooves 201 respectively located on both sides through the first fastener 4, so as to achieve a more stable fixation. Moreover, the air duct cover plate 3 can be engaged with the two slide grooves 201 at the same time when inserted, so as to help the air duct cover plate 3 maintain a stable position in the refrigeration air duct and reduce the possibility of shaking or displacement.

[0113] like Figure 7 and Fig. 9 As shown, in some embodiments, a slide groove 201 may be provided on two opposite side walls of the installation groove 203 , or a slide groove 201 may be provided on two opposite side walls of the installation groove 203 .

[0114] In some embodiments, the slide groove 201 may be provided in plurality. The plurality of slide grooves 201 may be distributed along the sidewall of the mounting groove 203 at intervals. The provision of the plurality of slide grooves 201 may provide a plurality of fixing points for the installation of the first fastener 4, thereby making the air duct cover plate 3 more firmly fixed in the mounting groove 203.

[0115] In some embodiments, the air duct cover plate 3 can cooperate with the slide groove 201 at multiple positions along the length direction of the side wall of the installation groove 203, so as to improve the stability of the connection between the air duct cover plate 3 and the box 2.

[0116] Fig.11 A schematic diagram of an air duct cover plate 3 according to an embodiment of the present application; Fig.12 for Fig.11 A partial enlarged view of point F;

[0117] Please see attached Fig.11 and attached Fig.12In some embodiments, the air duct cover plate 3 is provided with a plurality of first fasteners 4. The plurality of first fasteners 4 are arranged one by one with the slide grooves 201. In this way, the plurality of slide grooves 201 and the plurality of first fasteners 4 are correspondingly distributed and correspondingly snapped together, so that the air duct cover plate 3 can be evenly distributed when subjected to stress, reducing the possibility of local stress concentration, which is conducive to improving the durability of the air duct cover plate 3 and the entire refrigeration device.

[0118] like Fig.12 As shown, in some embodiments, the first buckle member 4 may include a first buckle portion 41. One end of the first buckle portion 41 may be connected to the air duct cover plate 3. The other end of the first buckle portion 41 may extend toward the rear side.

[0119] In some embodiments, the first buckle portion 41 can be disposed on a rear side wall of the air duct cover plate 3 that is disposed opposite to the box 2 .

[0120] It should be noted that, in other embodiments, the first buckle portion 41 may also be disposed on the side wall of the air duct cover 3 .

[0121] like Fig.12 As shown, in some embodiments, the first buckle 4 may include a second buckle portion 42. The second buckle portion 42 may be connected to the first buckle portion 41. The second buckle portion 42 may be arranged to extend from the rear end of the first buckle portion 41 toward one side of the first buckle portion 41, and the opening 202 of the first chute section 2011 can allow the second buckle portion 42 to pass through, so that the second buckle portion 42 can be engaged with the chute 201 located on the side of the air duct cover 3.

[0122] In some embodiments, the second buckle portion 42 can slide along the second chute section 2012 in a direction away from the first chute section 2011, so that the first buckle 4 is engaged in the second chute section 2012. By providing the second buckle portion 42, when the second buckle portion 42 is engaged in the second chute section 2012, the air duct cover plate 3 can be more firmly installed on the box 2. When the air duct cover plate 3 needs to be repaired or replaced, it is only necessary to simply slide the second buckle portion 42 out of the chute 201, which can reduce the difficulty of disassembly and installation, and greatly save maintenance time and cost.

[0123] In some embodiments, the first locking member 4 and the sliding slot 201 may extend in the same direction.

[0124] like Fig.12 As shown, in some embodiments, the first latch member 4 may be substantially L-shaped.

[0125] Please refer to the attached Figure 4In some embodiments, the refrigeration device further includes a connector 5. The connector 5 is detachably connected to the air duct cover plate 3. By providing the connector 5, the connection stability between the air duct cover plate 3 and the box 2 can be enhanced, so that the air duct cover plate 3 is more stable inside the refrigeration device, and the displacement or looseness caused by factors such as vibration and impact is reduced.

[0126] In some embodiments, through the cooperation of the first snap-fit ​​member 4 and the slide groove 201, and the fixation of the connecting member 5 through the air duct cover plate 3 and the box 2, the refrigeration device provides a double fixing mechanism, which can further enhance the connection stability between the air duct cover plate 3 and the box 2.

[0127] On the other hand, the connecting piece 5 is detachable, so when the air duct cover 3 needs to be repaired, cleaned or replaced, the operator can remove the connecting piece 5 so that the first clip can slide relative to the slide groove 201, and then the air duct cover 3 can be slid along the second slide groove 201 toward the first slide groove 201 and leave the first slide groove 201, thereby removing the air duct cover 3 from the box 2.

[0128] It should be noted that when the first fastener 4 slides along the second chute section 2012 in a direction away from the first chute section 2011, the first fastener 4 is engaged in the second chute section 2012, and the connector 5 can pass through the air duct cover plate 3 and the box 2 to fix the air duct cover plate 3 and the box 2. In this way, after the air duct cover plate 3 and the box 2 are fixedly engaged by the first fastener 4, further fixed connection can be achieved by the connector 5.

[0129] In some embodiments, the connection position of the connector 5 on the air duct cover plate 3 and the box 2 can be adjusted and adapted according to the size, shape and structure of different refrigeration devices and the air duct cover plate 3.

[0130] In some embodiments, the number of the connecting members 5 can be set to two. The two connecting members 5 can be respectively arranged near the top and the bottom.

[0131] In some other embodiments, the number of the connecting members 5 is not limited to two, and the number of the connecting members 5 can be one or more according to the requirements.

[0132] In some embodiments, the connector 5 may be a screw or a nut. The connector 5 makes the connection structure between the air duct cover plate 3 and the box 2 simpler and more effective, reduces the difficulty of installation, and is conducive to improving the installation and removal efficiency of the air duct cover plate 3 and the box 2.

[0133] It should be noted that, in some other embodiments, the design of the connector 5 can be adjusted and adapted according to the size, shape and structure of different refrigeration devices and air duct cover plates 3, so the refrigeration device has a wide range of applicability. For example, the connector 5 can also adopt a fixed pin structure.

[0134] like Figure 5 As shown, in some embodiments, the air duct cover plate 3 may be provided with a first connection hole 302. The first connection hole 302 may penetrate the plate surface of the air duct cover plate 3. The first connection hole 302 may allow the connector 5 to pass through, and the portion of the connector 5 passing through the first connection hole 302 may be connected to the box 2.

[0135] In some embodiments, the box 2 is provided with a second connection hole (not shown). The first connection hole 302 can be passed through by the connector 5, so that the portion of the connector 5 passing through the air duct cover plate 3 can be connected to the box 2 through the second connection hole.

[0136] In some embodiments, the air duct cover plate 3 may be provided with a first connection hole 302, and the box 2 may be provided with a second connection hole. The position and size of the second connection hole need to correspond to the first connection hole 302, so that the connector 5 can pass through the two holes smoothly.

[0137] In some embodiments, when the first fastener 4 slides along the second slide groove section 2012 in a direction away from the first slide groove section 2011, the first fastener 4 can be engaged in the second slide groove section 2012, and the first connecting hole 302 is correspondingly connected to the second connecting hole, so that the connecting member 5 can pass through the first connecting hole 302 and the second connecting hole to fix the air duct cover 3 and the box 2.

[0138] In some embodiments, when the first fastener 4 is at least partially located in the first slide groove section 2011, the first connection hole 302 is staggered with the second connection hole. In this way, when the relative position between the air duct cover plate 3 and the box liner 2 has not reached the final installation position, the connection holes cannot be aligned, and the air duct cover plate 3 and the box liner 2 cannot be connected together through the connecting member 5, thereby preventing the operator from misoperating and affecting the correct installation of the air duct cover plate 3 and the box liner 2.

[0139] In some embodiments, the first connection hole 302 may be a threaded hole, so that the connection member 5 (such as a screw, a bolt, etc.) can pass through the first connection hole 302 .

[0140] In some embodiments, the second connection hole may be a threaded hole, so that the connection member 5 (such as a screw, a bolt, etc.) can pass through the second connection hole.

Moreover, the plurality of second fasteners 7 are provided correspondingly to the plurality of first slots 601, which can disperse the connection points between the air duct foam 6 and the air duct cover plate 3, so that the connection between the air duct cover plate 3 and the air duct foam 6 is more uniform and stable.

[0150] like Fig.14 As shown, in some embodiments, a plurality of second fasteners 7 may be spaced apart and distributed on opposite sides of the air duct cover plate 3. A plurality of first slots 601 may be spaced apart and distributed on opposite sides of the air duct foam 6. In this way, the connection between the air duct cover plate 3 and the air duct foam 6 may be further made more uniform and stable, avoiding the problem of excessive local stress.

[0151] In some embodiments, the plurality of second fasteners 7 may be distributed on opposite left and right sides of the air duct cover 3 , or the plurality of second fasteners 7 may be distributed on opposite upper and lower sides of the air duct cover 3 .

[0152] In some embodiments, a plurality of second buckles 7 may be equally spaced and distributed on two opposite sides of the air duct cover 3. A plurality of first slots 601 may be equally spaced and distributed on two opposite sides of the air duct foam 6.

The air duct foam 6 may be provided with a second buckle slot 602 corresponding to the third buckle. The third buckle 8 may be at least partially inserted into the second buckle slot 602, which may provide an additional connection point for the connection between the air duct cover plate 3 and the air duct foam 6, and further strengthen the connection between the air duct cover plate 3 and the air duct foam 6.

[0154] like Fig.11As shown, in some embodiments, the third fastener 8 can be arranged away from the edge of the air duct cover plate 3. When the second fastener 7 is arranged on opposite sides of the air duct cover plate 3, the first card slot 601 is also correspondingly arranged on opposite sides of the air duct foam 6, so that the connection point between the air duct cover plate 3 and the air duct foam 6 is located at the edge, and by adding the arrangement of the third fastener 8, the tight connection between the air duct cover plate 3 and the air duct foam 6 can be further optimized, and the unstable connection between the middle part of the air duct foam 6 and the air duct cover plate 3 can be avoided, and the phenomenon of bulging in the middle of the air duct foam 6 can be effectively reduced.
