[0038] Referring to Figures 1 to 6 , the present application provides a refrigeration device, which may include: a refrigeration compartment 100, an air duct cover 200, and a first elastic member 230. A travel channel 111 may be recessed in the rear side wall of the refrigeration compartment 100. An elastic telescopic assembly 140 may be disposed on the inner peripheral wall at the front end of the travel channel 111. The telescopic end 1411 of the elastic telescopic assembly 140 can elastically extend axially toward the travel channel 111. The air duct cover 200 may be received in the refrigeration compartment 100. A limiting assembly 220 may be provided on the air duct cover 200 relative to the travel channel 111. The limiting assembly 220 may include a fixing rod 221 and a locking block 222. The front end of the fixing rod 221 may be connected to the air duct cover 200. The fixing rod 221 may extend from front to back. The locking block 222 may be disposed at the rear end of the fixing rod 221. The locking block 222 can abut against and move backward beyond the telescopic end 1411 to extend into the travel channel 111. The first elastic member 230 may be disposed between the air duct cover 200 and the rear side wall of the refrigeration compartment 100. The first elastic member 230 can apply a forward elastic force to the air duct cover 200 to drive the limiting assembly 220 to move forward. Wherein, the process of the locking block 222 moving backward includes a first stage and a second stage; in the first stage, the locking block 222 abuts against the front side of the telescopic end 1411 and can push the telescopic end 1411 to move away from the travel channel 111; in the second stage, the locking block 222 moves to the rear of the elastic telescopic assembly 140, and the telescopic end 1411 extends into the travel channel 111 and abuts against the front side of the locking block 222.

[0039] When the refrigeration device is assembled, the air duct cover 200 is moved backward into the refrigeration compartment 100. When the limiting assembly 220 moves backward so that the locking block 222 abuts against the telescopic end 1411, the locking block 222 is in the first stage. At this time, the locking block 222 squeezes the telescopic end 1411 so that the telescopic end 1411 moves away from the travel channel 111.

[0040] When the locking block 222 squeezes the telescopic end 1411 and moves backward beyond the telescopic end 1411, the locking block 222 extends into the travel channel 111. When the locking block 222 extends into the travel channel 111, the telescopic end 1411 moves axially toward the travel channel 111, and the first elastic member 230 applies an elastic force to the air duct cover 200 to make the locking block 222 move forward. The front side of the locking block 222 can abut against the telescopic end 1411, and the locking block 222 switches to the second stage. The locking block 222 switching from the first stage to the second stage can realize the rapid installation of the air duct cover 200, effectively prevent the air duct cover 200 or the refrigeration compartment 100 from being scratched and damaged during the traditional bolt and snap-fit installation process, and ensure the safety of the air duct cover 200 or the refrigeration compartment 100.

[0041] In this embodiment, the air duct cover plate 200 is detachably connected to the rear side wall of the refrigerating compartment 100. A refrigerating air duct is provided inside the air duct cover plate 200 so as to be capable of communicating with the refrigeration system.

[0042] Refer to Figures 1 to 3 、 Figure 5 As shown in FIGS. and, a first elastic member 230 may be provided on the rear side of the air duct cover plate 200 facing the refrigerating compartment 100. The first elastic member 230 can apply a forward elastic force to the air duct cover plate 200 to press the locking block 222 against the rear side of the telescopic end 1411, so that the locking block 222 switches to the second stage, thereby limiting the air duct cover plate 200 to the rear side of the refrigeration system through the limiting component 220, facilitating the rapid installation of the air duct cover plate 200.

[0043] In some embodiments, the first elastic member 230 may be in a plate shape, a ring shape or a block shape, so that the first elastic member 230 can fit against the rear side wall of the refrigerating compartment 100 and the air duct cover plate 200, and can apply a forward elastic force to the air duct cover plate 200. In some embodiments, the first elastic member 230 may be one or more, as long as it can apply a forward elastic force to the air duct cover plate 200. In some other embodiments, the first elastic member 230 may be a sponge ring or a rubber ring.

[0044] Refer to Figures 1 to 3 、 Figure 5 As shown in FIGS. and, in this embodiment, the air duct cover plate 200 may include a cover plate body 210 and a limiting component 220. The cover plate body 210 is detachably connected to the rear side wall of the refrigerating compartment 100 through the limiting component 220. A refrigerating air duct is provided inside the cover plate body 210.

[0045] The limiting component 220 may include a fixing rod 221 and a locking block 222. The fixing rod 221 is detachably connected to the rear side of the cover plate body 210, facilitating the assembly, disassembly and maintenance of the limiting component 220.

[0046] The user applies a backward pressure to the cover plate body 210 to move the cover plate body 210 backward. During the process of the cover plate body 210 moving toward the rear side wall of the refrigerating compartment 100, the locking block 222 switches from the first stage to the second stage. When the locking block 222 is in the first stage, the rear side of the locking block 222 abuts against and squeezes the telescopic end 1411, causing the telescopic end 1411 to move away from the stroke channel 111.

[0047] When the locking block 222 crosses the telescopic end 1411, the telescopic end 1411 of the elastic telescopic component 140 moves axially towards the stroke channel 111 under the action of its own elastic force. Then, the user stops applying pressure to the cover body 210, and the cover body 210 moves forward under the action of the first elastic member 230. The cover body 210 moves forward to drive the locking block 222 to move forward in the stroke channel 111 through the fixing rod 221, so that the front side of the locking block 222 abuts against the rear side of the telescopic end 1411, and the locking block 222 switches to the second stage.

[0048] When the locking block 222 is in the second stage, the limiting component 220 is limited in the stroke channel 111, and the cover body 210 is limited on the rear side wall of the refrigerating compartment 100. The cover body 210 is limited on the rear side wall of the refrigerating compartment 100 through the limiting component 220, which can prevent scratches during the installation and disassembly of the air duct cover 200 on the refrigerating compartment 100, and improve the safety of the refrigeration equipment.

[0049] In some embodiments, the front end of the fixing rod 221 is threadedly connected to the cover body 210.

[0050] Figure 7 It is a schematic structural diagram of the embedded block and the limiting component of the present utility model. Figure 8 It is a schematic structural diagram of the embedded block and the limiting component when the locking block of the present utility model is in the first stage. Figure 9 It is a schematic structural diagram of the embedded block and the limiting component when the locking block of the present utility model is in the second stage.

[0051] Refer to Figures 6 to 9 In this embodiment, the locking block 222 can be connected to the rear end of the fixing rod 221, so as to facilitate the installation, disassembly and maintenance of the locking block 222.

[0052] In some embodiments, the locking block 222 and the fixing rod 221 can be threadedly connected, snap-connected or riveted.

[0053] In other embodiments, the locking block 222 and the fixing rod 221 can be integrally formed. The fixing rod 221 is detachably connected to the cover body 210. In other embodiments, the fixing rod 221 and the cover body 210 can be bolted, snap-connected or tenon-mortise connected.

[0054] Refer to Figures 6 to 9, in this embodiment, the rear side of the locking block 222 may be a first guiding inclined surface 2221. The first guiding inclined surface 2221 is arranged relative to the telescopic end 1411. In the front-to-back direction, the first guiding inclined surface 2221 extends towards the middle of the locking block 222. When the locking block 222 is in the first stage, the first guiding inclined surface 2221 of the locking block 222 can abut against and squeeze the telescopic end 1411, so as to push the telescopic end 1411 to axially move away from the stroke channel 111.

[0055] Refer to Figures 6 to 9 , in this embodiment, in the front-to-back direction, the rear part of the locking block 222 may be a conical structure with a gradually decreasing cross-sectional area. In some embodiments, in the front-to-back direction, the locking block 222 may be a frustum-shaped structure or a prism-shaped structure with a gradually decreasing cross-sectional area.

[0056] In some embodiments, a plurality of first guiding inclined surfaces 2221 may be provided on the rear part of the locking block 222. The first guiding inclined surfaces 2221 are arranged relative to the elastic telescopic assembly 140, so that when the locking block 222 is in the first stage, the locking block 222 can squeeze the telescopic end 1411 through the first guiding inclined surfaces 2221 and cross over the elastic telescopic assembly 140, and then extend into the stroke channel 111.

[0057] Figure 10 is a schematic structural diagram of the embedded block and the limiting assembly when the movable block of the present utility model is in the second state. Figure 11 is a schematic structural diagram of the movable block and the locking block of the present utility model when they exit the stroke channel.

[0058] Refer to Figures 6 to 11 , in this embodiment, the limiting assembly 220 may further include a movable block 223. The movable block 223 is slidably sleeved on the fixed rod 221 in the front-to-back direction. The movable block 223 can move backward to push the telescopic end 1411 to move away from the stroke channel 111.

[0059] The movable block 223 has a first state and a second state. When the movable block 223 is in the first state, the movable block 223 is located outside the stroke channel 111. The movable block 223 can move backward and push the telescopic end 1411 to move away from the stroke channel 111, so that the movable block 223 extends into the stroke channel 111 and switches to the second state.

[0060] When the movable block 223 is in the second state, the limiting assembly 220 can move forward, and the movable block 223 can push the telescopic end 1411 to move away from the stroke channel 111, so that the movable block 223 can drive the locking block 222 to move forward out of the stroke channel 111.

[0061] When disassembling the air duct cover plate 200, the user presses the cover plate body 210 backward, so that the cover plate body 210 moves backward and squeezes the movable block 223 to move backward. The movable block 223 switches to the first state, and the movable block 223 continuously moves backward under the action of an external force to push the telescopic end 1411 away from the stroke channel 111. When the movable block 223 moves backward beyond the telescopic end 1411 and extends into the stroke channel 111, the movable block 223 switches to the second state.

[0062] After that, the user stops applying a backward pressure to the cover plate body 210, and the cover plate body 210 moves forward under the elastic force of the first elastic member 230, so that the fixing rod 221 drives the locking block 222 to move forward. The locking block 222 presses forward on the movable block 223 and presses the movable block 223 against the rear side of the telescopic end 1411. Finally, the user and / or the first elastic member 230 apply a forward force to the cover plate body 210, so that the cover plate body 210 drives the locking block 222 and the movable block 223 to move forward. The movable block 223 pushes the telescopic end 1411 away from the stroke channel 111, and the movable block 223 and the locking block 222 move out of the stroke channel 111, thereby disassembling the air duct cover plate 200.

[0063] In some embodiments, when the movable block 223 is in the second state, the movable block 223 can be attached to the locking block 222. The edge of the rear side surface of the movable block 223 can extend beyond or coincide with the outer periphery of the locking block 222 in the direction towards the telescopic end 1411.

[0064] Refer to Figures 6 to 11 In this embodiment, one side of the movable block 223 facing the telescopic end 1411 can be the second guiding inclined surface 2231. The second guiding inclined surface 2231 is disposed opposite to the elastic telescopic assembly 140. In the direction from back to front, the second guiding inclined surface 2231 extends towards the middle of the movable block 223.

[0065] In some embodiments, the movable block 223 can be a prismatic structure. In some embodiments, in the direction from back to front, the movable block 223 can be a conical structure with a gradually decreasing cross-sectional area. In other embodiments, in the direction from back to front, the movable block 223 can be a frustum-shaped structure such as a frustum of a cone or a frustum of a prism with a gradually decreasing cross-sectional area.

[0066] In some embodiments, a plurality of second guiding inclined surfaces 2231 can be provided at the front end of the movable block 223, so that when the movable block 223 is in the second state, the movable block 223 can push the telescopic end 1411 to move axially away from the stroke channel 111, and the movable block 223 can drive the locking block 222 to move out of the stroke channel 111.

[0067] Refer to Figures 6 to 11, in this embodiment, the limiting component 220 may further include an abutting block 224. The abutting block 224 protrudes from the rear side wall of the air duct cover plate 200, the abutting block 224 extends in the front-rear direction, and the rear end of the abutting block 224 can abut against the front side of the movable block 223 to press the movable block 223 into the stroke channel 111.

[0068] When the cover body 210 moves backward, the cover body 210 drives the fixing rod 221 and the locking block 222 to move backward. The abutting block 224 can abut against the movable block 223 and press the movable block 223 to the first state. Then, the abutting block 224 continuously applies a backward pressure to the movable block 223 so that the movable block 223 moves backward beyond the telescopic end 1411 and switches to the second state, thereby reducing the backward movement stroke of the cover body 210 and facilitating the disassembly of the air duct cover plate 200.

[0069] In some embodiments, the abutting block 224 and the cover body 210 are integrally formed. In other embodiments, a threaded hole is provided at the rear end of the abutting block 224 so that the abutting block 224 can be threadedly connected to the front end of the fixing rod 221.

[0070] In other embodiments, in the front-to-back direction, the abutting block 224 may have a frustum-shaped structure or a truncated pyramid-shaped structure with a gradually decreasing cross-sectional area. In other embodiments, in the front-to-back direction, the abutting block 224 may have a conical structure with a gradually decreasing cross-sectional area.

[0071] Refer to Figure 3 、 Figure 4 and Figure 5 , in this embodiment, there may be a plurality of limiting components 220, and the plurality of limiting components 220 are arranged at intervals on the rear side of the cover body 210 to detachably limit the cover body 210 to the rear side wall of the refrigerating compartment 100. The plurality of limiting components 220 can improve the connection stability and reliability between the cover body 210 and the rear side wall of the refrigerating compartment 100.

[0072] In some embodiments, there may be a plurality of stroke channels 111 corresponding to the plurality of limiting components 220.

[0073] In this embodiment, a stroke channel 111 may be recessed on the rear side wall of the refrigerating compartment 100 for the limiting structure to extend into and out of. An elastic telescopic component 140 may be provided on the inner peripheral wall at the front end of the stroke channel 111, and the telescopic end 1411 of the elastic telescopic component 140 can elastically extend toward the axis of the stroke channel 111 for abutting against and limiting the locking block 222.

[0074] On the inner peripheral wall of the stroke channel 111, a telescopic groove 1321 may be recessed. The telescopic groove 1321 can accommodate the elastic telescopic component 140, so that the telescopic end 1411 of the elastic telescopic component 140 can elastically extend toward the axis of the stroke channel 111 or elastically contract away from the axis of the stroke channel 111, thereby facilitating the locking block 222 to switch from the first stage to the second stage, the movable block 223 to switch from the first state to the second state, or the movable block 223 to drive the locking block 222 to move out of the stroke channel 111.

[0075] In some embodiments, a plurality of telescopic grooves 1321 may be recessed on the inner peripheral wall at the front end of the stroke channel 111. The plurality of telescopic grooves 1321 may be arranged at intervals around the circumference of the stroke channel 111 to respectively accommodate a plurality of elastic telescopic components 140, thereby improving the limiting strength between the elastic telescopic component 140 and the locking block 222 and enhancing the connection strength between the air duct cover 200 and the rear side wall of the refrigerating compartment 100. In other embodiments, the axes of the plurality of telescopic grooves 1321 are located in the same plane to improve the reliability of the elastic telescopic component 140 and enhance the connection strength between the air duct cover 200 and the rear side wall of the refrigerating compartment 100.

[0076] Refer to Figures 1 to 3 、 Figures 7 to 11 , in this embodiment, the refrigerating compartment 100 may include an inner container 120 and an embedded block 130. A through hole 121 is formed on the rear side wall of the inner container 120. The embedded block 130 may be located at the rear of the inner container 120 and be attached to the inner container 120. A stroke groove 1311 may be recessed on the front side wall of the embedded block 130. The stroke groove 1311 may communicate with the through hole 121 to form a stroke channel 111. A telescopic groove 1321 may be recessed on the inner peripheral wall at the front end of the stroke groove 1311, and the telescopic groove 1321 is used to accommodate the elastic telescopic component 140.

[0077] In some embodiments, the embedded block 130 may include a main body portion 131 and a receiving portion 132. The main body portion 131 may be attached to the inner container 120. A stroke groove 1311 may be formed on the side wall of the main body portion 131 facing the inner container 120. The receiving portion 132 is wound around the peripheral side of the front end of the main body portion 131. A telescopic groove 1321 is formed at the front end of the main body portion 131, and the telescopic groove 1321 can extend into the receiving portion 132 to reduce the production material of the embedded block 130, thereby reducing the production cost of the embedded block 130.

[0078] In other embodiments, the main body portion 131 and the receiving portion 132 are detachably connected. On the one hand, it is convenient to install the elastic telescopic component 140 into the telescopic groove 1321 of the embedded block 130, or to disassemble and repair the elastic telescopic component 140; on the other hand, it is convenient for the injection molding of the embedded block 130, reduces the difficulty of mold opening, and improves the production efficiency of the embedded block 130.

[0079] In some other embodiments, the accommodating portion 132 is snap-connected, thread-connected or riveted to the main body portion 131.

[0080] Referring to Figures 7 to 11 , in this embodiment, the elastic telescopic assembly 140 may include a telescopic column 141 and a second elastic member 142. One end of the telescopic column 141 is accommodated in the telescopic groove 1321, and the other end of the telescopic column 141 is a telescopic end 1411 so as to be able to extend into the stroke channel 111. The second elastic member 142 may be accommodated in the telescopic groove 1321, and the second elastic member 142 abuts against the telescopic column 141 and the inner wall of the telescopic groove 1321 so as to be able to apply an elastic force to the telescopic column 141 for axially moving towards the stroke channel 111.

[0081] When the locking block 222 is in the first stage, the first guiding inclined surface 2221 of the locking block 222 abuts against and presses the front side of the telescopic end 1411, so that the telescopic column 141 axially moves away from the stroke channel 111 and presses the second elastic member 142, and the second elastic member 142 converts the pressure into elastic potential energy.

[0082] When the locking block 222 passes over the telescopic end 1411, after the second elastic member 142 loses the external force extrusion, the elastic potential energy is converted into the elastic force applied to the telescopic column 141. After the telescopic column 141 receives the elastic force of the second elastic member 142, the telescopic end 1411 axially moves towards the stroke channel 111. Moreover, the locking block 222 moves forward under the elastic force of the first elastic member 230, so that the front side of the locking block 222 abuts against the rear side of the telescopic end 1411, and the locking block 222 switches to the second stage. The locking block 222 is limited in the telescopic channel under the action of the telescopic end 1411, so that the air duct cover 200 is limited to the rear side wall of the refrigerating compartment 100 through the limiting assembly 220.

[0083] When the user disassembles the air duct cover 200, the user presses the cover body 210 backward, so that the abutting block 224 presses the movable block 223 backward. The movable block 223 moves backward to abut against and press the telescopic end 1411. The movable block 223 moves to the first state, so that the telescopic end 1411 axially moves away from the stroke channel 111. After the movable block 223 passes over the telescopic end 1411 from the first state, it switches to the second state. When the movable block 233 switches to the second state, the user can apply a forward pulling force to the cover body 210, so that the rear side of the movable block 223 fits against the front side of the locking block 222, and the movable block 223 drives the locking block 222 to pass over the telescopic end 1411 to move out of the stroke channel 111.

[0084] In some embodiments, a third guiding inclined surface 1412 and a fourth guiding inclined surface 1413 may be respectively provided on the telescopic end 1411 of the elastic telescopic assembly 140. The third guiding inclined surface 1412 is located on the front side of the fourth guiding inclined surface 1413. In the direction towards the axis of the stroke channel 111, the third guiding inclined surface 1412 and the fourth guiding inclined surface 1413 extend towards each other. In a plane perpendicular to the front-rear direction, the projection of the fourth guiding inclined surface 1413 is within the projection range of the locking block 222, so as to facilitate the front side of the locking block 222 to abut against and limit the rear side of the telescopic end 1411.

[0085] In some embodiments, in a plane perpendicular to the front-rear direction, the projection of the movable block 223 is within the enclosed range of the projection of the third guiding inclined surface 1412, so as to facilitate the movable block 223 to abut against and push the telescopic end 1411 to move away from the axis of the stroke channel 111 in the first state, and facilitate the movable block 223 to switch from the first state to the second state.

[0086] In some embodiments, when the fourth guiding inclined surface 1413 is not provided, only the third guiding inclined surface 1412 is provided on the telescopic end 1411. In a plane perpendicular to the front-rear direction, the projection of the telescopic end 1411 is within the enclosed range of the projection of the second guiding inclined surface 2231, so that the second guiding inclined surface 2231 can push the telescopic end 1411 to move away from the axis of the stroke channel 111.

[0087] In other embodiments, when the third guiding inclined surface 1412 and the fourth guiding inclined surface 1413 are not provided, the telescopic end 1411 has a columnar structure. In a plane perpendicular to the front-rear direction, the projection of the telescopic end 1411 is within the enclosed range of the projection of the first guiding inclined surface 2221 and the projection of the second guiding inclined surface 2231, so that when the locking block 222 switches from the first stage to the second stage and the movable block 223 drives the locking block 222 to move out of the stroke channel 111 from the second stage, both the locking block 222 and the movable block 223 can squeeze and push the telescopic end 1411 to move away from the axis of the stroke channel 111.

[0088] In other embodiments, the telescopic end 1411 of the elastic telescopic assembly 140 has a conical structure, a frustum-shaped structure or a prism-shaped structure. The conical telescopic end 1411 can contact the rear side wall of the locking block 222, and the conical telescopic end 1411 is located on the side of the peripheral side wall of the locking block 222 close to the axis of the fixed rod 221, so that the rear side of the locking block 222 can squeeze and push open the telescopic rod, and the front side of the locking block 222 can fit and be limited on the rear side wall of the telescopic rod.

[0089] Refer to Figures 7 to 11, in this embodiment, the second elastic member 142 can be a compression spring. In some embodiments, the compression spring can be sleeved on one end of the telescopic column 141 facing away from the stroke channel 111, so as to apply an elastic force to the telescopic column 141 to axially move towards the stroke channel 111.

[0090] In some embodiments, in the direction axially away from the stroke channel 111, the cross-sectional area of one end of the telescopic column 141 facing away from the stroke channel 111 gradually decreases, so as to facilitate the mutual limitation between the telescopic column 141 and the compression spring.

[0091] Refer to Figure 2 , Figure 3 and Figure 5 , in this embodiment, there can be multiple elastic telescopic assemblies 140. The multiple elastic telescopic assemblies 140 can be arranged at intervals in the circumferential direction of the stroke channel 111, and the multiple elastic telescopic assemblies 140 can be respectively accommodated in multiple telescopic slots 1321 to improve the connection strength between the air duct cover 200 and the rear side wall of the refrigerating compartment 100.

[0092] In some embodiments, the axes of the multiple elastic telescopic assemblies 140 are located in the same plane, so as to facilitate the insertion and limitation of the locking block 222 in the stroke channel 111, and facilitate the movable block 223 to drive the locking block 222 to move out of the stroke channel 111, thereby improving the installation and disassembly efficiency of the air duct cover 200.

[0093] Refer to Figures 1 to 11 , in the present utility model, when the air duct cover 200 is installed, the air duct cover 200 is moved into the refrigerating compartment 100 and moved backward towards the rear side wall of the refrigerating compartment 100.

[0094] When the cover body 210 moves backward and the first guiding inclined surface 2221 of the locking block 222 abuts against the third guiding inclined surface 1412 of the telescopic end 1411, the locking block 222 moves to the first stage. After that, the cover body 210 continues to move backward, the locking block 222 moves backward and pushes the telescopic end 1411 to axially move away from the stroke channel 111. When the locking block 222 moves backward and passes over the telescopic end 1411, the user stops applying a backward pressure to the cover body 210, and the locking block 222 moves forward under the action of the first elastic member 230 and abuts against the rear side wall of the telescopic end 1411, so that the locking block 222 switches to the second stage. After the locking block 222 switches to the second stage, the locking block 222 is limited in the stroke channel 111, which is convenient for the cover body 210 to be installed on the rear side wall of the refrigerating compartment 100 and improves the installation efficiency of the air duct cover 200.

[0095] When the air duct cover 200 needs to be disassembled and repaired, the user applies a backward pressure to the cover body 210. The abutting block 224 on the cover body 210 abuts against and squeezes the movable block 223 backward, and the movable block 223 moves backward under the action of the abutting block 224. The movable block 223 moves backward and abuts against the front side of the telescopic end 1411, and the movable block 223 moves to the first state.

[0096] When the movable block 223 moves backward to the first state, the user applies a backward force to the cover body 210 to make the movable block 223 abut against and push the telescopic end 1411 to move axially away from the stroke channel 111. When the movable block 223 moves backward beyond the telescopic end 1411, the movable block 223 switches from the first state to the second state.

[0097] When the movable block 223 switches to the second state, the user starts to apply a forward pulling force to the cover body 210. The cover body 210 moves forward and makes the locking block 222 abut against the movable block 223 forward. During the forward movement of the movable block 223, the second guiding inclined surface 2231 can abut against the fourth guiding inclined surface 1413, and the movable block 223 can push the telescopic end 1411 to move axially away from the stroke channel 111, so that the movable block 223 can drive the locking block 222 to move beyond the telescopic end 1411 and out of the stroke channel 111, thus facilitating the disassembly of the air duct cover 200 and improving the disassembly efficiency of the refrigeration equipment.

Therefore, all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
