Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and more particularly to a refrigerator. Background Technology

[0002] Refrigerators often have storage drawers, which are usually located at the bottom or side of the refrigerator compartment. These drawers provide independent storage space for food, and their sealed design reduces air exchange between the inside of the drawer and the refrigerator compartment, minimizing moisture loss and extending the shelf life of the food.

[0003] In related technologies, a storage drawer is pull-out and installed in the refrigerator compartment. A shelf assembly is provided on the top of the storage drawer. When the storage drawer is closed, the shelf assembly covers the top of the storage drawer to cover the top opening of the storage drawer.

[0004] However, the shelf assembly uses screws to fasten the shelf covers to the storage drawer covers. Assembly requires using screwdrivers and other tools to tighten each screw individually, a tedious and time-consuming process that reduces the assembly efficiency of the shelf assembly. Utility Model Content

[0005] This application provides a refrigerator that can solve the technical problem of low assembly efficiency of the shelf components in related refrigerators.

[0006] This application provides a refrigerator, including:

[0007] The inner liner forms a refrigeration compartment;

[0008] The air duct assembly has an air cavity that is connected to the refrigeration compartment;

[0009] Storage drawers, which can be pulled out and installed in the refrigeration room, have storage compartments with top openings;

[0010] Shelf assembly, installed in the refrigeration compartment; shelf assembly includes:

[0011] When the storage drawer is closed, the drawer lid covers the top opening of the storage cavity; the drawer lid has an air inlet and an air outlet, the air inlet is connected to the air cavity, and the air outlet is connected to the storage cavity; the top of the drawer lid is provided with a first snap-fit ​​structure.

[0012] An air duct component is installed on the top of the drawer lid. The air duct component is used to form a guide air duct, which is connected to the air inlet and the air outlet respectively. The air duct component is constructed with clearance holes, and the first snap-fit ​​structure is inserted into the clearance holes.

[0013] The partition cover covers the top of the drawer cover and the air duct component respectively. The bottom of the partition cover is provided with a second snap-fit ​​structure, which passes through the clearance hole and snaps with the first snap-fit ​​structure.

[0014] In the refrigerator of this application embodiment, the second snap-fit ​​structure passes through the clearance hole and snaps into the first snap-fit ​​structure. This not only realizes the snap-fit ​​cooperation between the drawer cover and the partition cover, but also fixes the air duct component between the drawer cover and the partition cover, shortening the assembly time of the shelf assembly and improving the assembly efficiency of the shelf assembly.

[0015] In some embodiments of this application, the bottom of the air duct component is constructed with a downward-facing guide groove, and the drawer cover closes to the opening of the guide groove, forming a guide air duct with the air duct component.

[0016] This design utilizes part of the drawer lid's structure to reduce the material consumption of the air duct components and lower the cost of the refrigerator.

[0017] In some embodiments of this application, the air duct component includes:

[0018] The air duct plate is positioned opposite the drawer lid, and the air duct plate and the drawer lid together form a guide air duct; the air duct plate has clearance holes.

[0019] A baffle is provided on the side of the air duct plate facing the drawer lid and is positioned opposite to the clearance hole; the clearance hole passes through the baffle, and the baffle surrounds at least a portion of the outer periphery of the clearance hole; the baffle overlaps the drawer lid.

[0020] This design reduces the gap between the air duct components and the drawer lid along the height of the inner box, making it difficult for cold air in the air duct to flow into the clearance hole. With the total air volume flowing into the air duct from the air inlet remaining unchanged, the amount of air leaking from the clearance hole is reduced, thereby increasing the amount of air flowing into the storage cavity and improving the cooling effect on the items in the storage drawer.

[0021] In some embodiments of this application, the first snap-fit ​​structure includes two first connecting arms that are opposite to each other and spaced apart. The bottom end of the first connecting arm is connected to the top of the drawer lid, and the top ends of the opposite sides of the two first connecting arms are respectively provided with first stop portions.

[0022] The second snap-fit ​​structure includes two second connecting arms that are opposite to each other and spaced apart. The top of the second connecting arms is connected to the bottom of the partition cover. The bottom of the opposite side of the two second connecting arms is provided with a second stop. The two second stops pass downward through the gap between the two first stops and are respectively opposite to the corresponding first stops.

[0023] With this configuration, the two second stops pass downward through the gap between the two first stops and are respectively opposite to the corresponding first stops. In other words, there is a first stop above each second stop, and the first stops stop above the second stops, so that the second stops are not easy to come out of the gap between the two first stops, thus improving the reliability of the connection between the partition cover and the drawer cover.

[0024] In some embodiments of this application, the partition cover is provided with slides on both sides along the width direction of the box liner, the slides extend along the depth direction of the box liner, and the rear end of the slides penetrates through the partition cover.

[0025] The liner includes two sidewalls that are opposite to each other and spaced apart along its width. The sidewalls are equipped with guide ribs that protrude toward the refrigeration compartment. The guide ribs extend along the depth direction and are located in the slide rails and slide in cooperation with the slide rails.

[0026] With this setup, when installing the shelf assembly into the cabinet, the rear end of the slide rail is aligned with the front end of the guide rib. Then, the shelf assembly is moved backward so that the guide rib is positioned within the slide rail. The shelf assembly is then moved backward until it is fully installed inside the refrigeration room, thus completing the assembly of the shelf assembly and the cabinet. This operation is simple, time-saving, and labor-saving, improving the assembly efficiency of the shelf assembly and the cabinet.

[0027] In some embodiments of this application, the partition cover includes:

[0028] The upper plate has a second snap-fit ​​structure at its bottom;

[0029] The first side panel has its top end connected to the bottom of the upper panel.

[0030] The support part is located on the side of the first side plate facing the gallbladder side wall. The support part is partially opposite to and spaced apart from the upper plate body. The support part, the first side plate and the upper plate body together form a slide.

[0031] With this configuration, after the shelf assembly is fixedly mounted on the guide rib of the cabinet, the upper plate overlaps the top of the guide rib, the first side plate stops at the end of the guide rib near the refrigeration compartment along the width direction, and the support part supports the bottom of the guide rib, so that the support part, the first side plate and the upper plate form a slide with a cross section that is approximately matched with the cross section of the guide rib. This slide can slide with the guide rib and limit the possibility of the partition cover swaying relative to the cabinet in the height and width directions, thereby improving the stability of the connection between the shelf assembly and the cabinet.

[0032] In some embodiments of this application, the sidewall of the gallbladder is further provided with a limiting recess that is opposite to the recess of the refrigeration compartment;

[0033] The partition cover has a third snap-fit ​​structure on both sides along the width direction, and part of the third snap-fit ​​structure is snapped into the limiting recess.

[0034] With this configuration, after the shelf assembly and the inner box are assembled, part of the third snap-fit ​​structure is engaged in the limiting recess to further reduce the possibility of the partition cover and shelf assembly wobbling relative to the inner box in the height and width directions, thereby improving the stability of the connection between the shelf assembly and the inner box.

[0035] In some embodiments of this application, the third snap-fit ​​structure includes a third connecting arm and a third stop portion; the third stop portion is disposed at one end of the third connecting arm and is located on the side of the third connecting arm facing the gallbladder sidewall; the end of the third connecting arm away from the third stop portion is connected to the sidewall of the partition cover.

[0036] With this configuration, when the shelf assembly moves relative to the inner liner until the third stop contacts the inner liner sidewall, as the shelf assembly moves further backward, the inner liner sidewall gradually presses against the third stop and causes the third connecting arm to deform to a certain extent, causing the third stop to move away from the inner liner sidewall. This allows the shelf assembly to move further backward until the third stop moves into the limiting recess. At this point, the third connecting arm resets, and the third stop moves into the limiting recess. Due to the stopping effect of the sidewall of the limiting recess on the third stop, the shelf assembly can no longer move backward. At this point, the shelf assembly and the inner liner are assembled in place.

[0037] In some embodiments of this application, the sidewall of the bladder is further provided with a stop rib protruding toward the refrigeration compartment. The stop rib is located behind the guide rib, and the front side of the stop rib has a stop surface. The stop surface is opposite to the rear end of the partition cover and is used to stop the rear end of the partition cover.

[0038] With this configuration, when the shelf assembly slides backward along the guide rib, when the rear end of the partition cover moves to contact the stop surface, the stop surface will prevent the partition cover from moving further backward, thus limiting the rear end position of the shelf assembly during installation and reducing the possibility of collision between the shelf assembly and components inside the rear of the cabinet (such as air duct components).

[0039] In some embodiments of this application, the drawer lid includes:

[0040] The lower plate has a first snap-fit ​​structure at its top;

[0041] The second side panel is connected at its bottom to the top of the lower panel, and the second side panel is snapped into the partition cover.

[0042] With this design, the second side panel engages with the partition cover to secure the edges of the drawer cover and partition cover, thus improving the reliability of the connection between the drawer cover and partition cover. Attached Figure Description

[0067] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0068] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0069] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0070] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0071] As stated in the background art, refrigerators in the related art suffer from low assembly efficiency of shelf components. The inventors have discovered that the reason for this problem is that the shelf cover and the storage drawer cover in the shelf component are fixed with screws. During assembly, screwdrivers and other tools are required to tighten the screws one by one, which is a cumbersome and time-consuming process, thus reducing the assembly efficiency of the shelf component.

[0072] To address the aforementioned technical problems, this application provides a refrigerator with a first snap-fit ​​structure on the top of the drawer cover and a second snap-fit ​​structure on the bottom of the shelf cover. An air duct component is provided between the drawer cover and the shelf cover, and a clearance hole is constructed on the air duct component. Both the first and second snap-fit ​​structures pass through the clearance hole and are snap-fitted together. This not only achieves the snap-fit ​​cooperation between the drawer cover and the shelf cover but also fixes the air duct component between the drawer cover and the shelf cover, shortening the assembly time of the shelf assembly and improving the assembly efficiency of the shelf assembly.

[0073] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0074] refer to Figure 1 The refrigerator provided in this application includes a cabinet 10 having a cooling compartment 111, a door connected to the cabinet 10 to open or close the cooling compartment 111, and a refrigeration device for supplying cold air to the cooling compartment 111. The cooling compartment 111 is used to house items requiring low-temperature storage.

[0075] refer to Figure 1 The cabinet 10 may include a cabinet liner 110. The cabinet liner 110 may form a refrigeration compartment 111. A pick-up and drop-off port may be formed on the front side of the refrigeration compartment 111. The pick-up and drop-off port is connected to the refrigeration compartment 111. Items can be taken out from the refrigeration compartment 111 through the pick-up and drop-off port, or items can be placed into the refrigeration compartment 111 through the pick-up and drop-off port.

[0076] It should be noted that in the description of the embodiments in this application, Figure 1 The positive direction of the depth Y of the middle chamber 110 is "front", and the negative direction of the depth Y is "back".

[0077] Understandably, the number of inner chambers 110 can be two or more. The refrigeration compartment 111 can be configured as a refrigerator compartment, a freezer compartment, or a variable temperature compartment.

[0078] refer to Figure 1 The housing 10 may also include a housing shell 120. The housing shell 120 is attached to the outside of the housing liner 110 to form the appearance of the housing 10.

[0079] In some possible implementations of the embodiments of this application, the door can be rotatably connected to the housing 10 to open or close the refrigeration compartment 111.

[0080] The refrigeration unit can be installed inside the enclosure 10. The refrigeration unit is used to provide cold air to the refrigeration chamber 111 to reduce the temperature inside the refrigeration chamber 111.

[0081] A refrigeration unit may include a compressor, a condenser, a throttling element, and an evaporator. The throttling element may be a capillary tube or an electronic expansion valve, etc. The compressor, condenser, throttling element, and evaporator may be connected in series via pipes, through which refrigerant may flow.

[0082] When the refrigerator cools the cooling compartment 111, the refrigerant circulates within the compressor, condenser, throttling element, and evaporator. As it flows through the evaporator, it absorbs heat and lowers the temperature of the evaporator and the surrounding air. The air flowing through the evaporator is then delivered into the cooling compartment 111 to reduce the temperature inside the cooling compartment 111.

[0083] In some possible implementations of the embodiments of this application, reference is made to Figure 1 , Figure 2 , Figure 3 and Figure 4 The refrigerator may also include an air duct assembly 20, which is used to guide cold air from the evaporator into the cooling compartment 111 to reduce the temperature inside the cooling compartment 111. Part of the air duct assembly 20 may be located inside the refrigerator liner 110.

[0084] refer to Figure 4 The air duct assembly 20 can form an air cavity 210, which is connected to the cooling chamber 111. The air cavity 210 can also be connected to the chamber where the evaporator is located, so as to deliver the cold air after heat exchange with the evaporator to the air cavity 210, and then deliver it to the cooling chamber 111 through the air cavity 210 to reduce the temperature in the cooling chamber 111.

[0085] refer to Figure 1 and Figure 2 The refrigerator in this embodiment of the application also includes a storage drawer 30, which has a storage cavity 301 with a top opening. The storage drawer 30 is pull-out disposed in the refrigeration compartment 111.

[0086] The storage drawer 30 can be installed inside the refrigeration compartment 111, and the storage drawer 30 can be slidably installed in the inner liner 110 to open or close the top opening of the storage cavity 301.

[0087] refer to Figure 1 and Figure 2 The refrigerator also includes a shelf assembly 40, which is disposed within the refrigeration compartment 111. When the storage drawer 30 is closed, the shelf assembly 40 covers the top opening of the storage cavity 301, creating a relatively sealed environment within the storage cavity 301. This reduces the amount of dry air from the refrigeration compartment 111 entering the storage cavity 301, thereby reducing the rate of moisture evaporation from food within the storage cavity 301 and extending the shelf life of the food.

[0088] In some possible implementations of the embodiments of this application, reference is made to Figure 3 and Figure 4 The inner container 110 may include two inner container sidewalls 114, which may be arranged opposite to each other and spaced apart along the width direction X of the inner container 110.

[0089] refer to Figure 4 and Figure 5 The side wall 114 of the inner chamber may be constructed with guide ribs 115 protruding toward the refrigeration compartment 111, and the guide ribs 115 extend along the depth direction Y of the inner chamber 110.

[0090] refer to Figure 4 The shelf assembly 40 may have slides 435 on both sides along the depth direction Y of the box liner 110. The slides 435 extend along the depth direction Y of the box liner 110, and the rear end of the slides 435 penetrates the shelf assembly 40.

[0091] When installing the shelf assembly 40 into the liner 110, align the rear end of the slide rail 435 with the front end of the guide rib 115, then move the shelf assembly 40 backward so that the guide rib 115 is positioned within the slide rail 435. Continue moving the shelf assembly 40 backward until it is fully moved into the refrigeration compartment 111. This completes the assembly of the shelf assembly 40 and the liner 110. The operation is simple, time-saving, and labor-saving, improving the assembly efficiency of the shelf assembly 40 and the liner 110.

[0092] The guide rib 115 can guide the shelf assembly 40 to facilitate its connection to the box liner 110. The guide rib 115 can also support the shelf assembly 40 to secure it to the box liner 110.

[0093] refer to Figure 6 , Figure 7 and Figure 8The shelf assembly 40 in this embodiment may include a drawer cover 410, an air duct component 420, and a partition cover 430.

[0094] The drawer cover 410 is located above the storage drawer 30. When the storage drawer 30 is closed, the drawer cover 410 covers the top opening of the storage cavity 301.

[0095] refer to Figure 9 and Figure 10 The air duct component 420 is disposed on the top of the drawer cover 410. The air duct component 420 is used to form the air duct 4211.

[0096] In some embodiments, the air duct 420 may be configured with a guide air duct 4211.

[0097] In other embodiments, reference is made to Figure 10 The air duct component 420 can be enclosed with the drawer cover 410 to form a guide air duct 4211. The guide air duct 4211 utilizes part of the structure of the drawer cover 410, reducing the material consumption of the air duct component 420 and lowering the cost of the refrigerator.

[0098] In some possible implementations of the embodiments of this application, reference is made to Figure 7 The air duct component 420 may include an air duct plate 421, the bottom of which may be constructed with a downward-facing guide groove 4223. The air duct plate 421 is disposed opposite to the drawer cover 410, and the drawer cover 410 closes to the groove of the guide groove 4223, so that the air duct plate 421 and the drawer cover 410 enclose and form a guide air duct 4211.

[0099] refer to Figure 7 and Figure 8 The air duct plate 421 has a clearance hole 4222, which penetrates the air duct plate 421.

[0100] refer to Figure 7 and Figure 10 The air duct component 420 may further include a baffle plate 422, which is disposed on the side of the air duct plate 421 facing the drawer cover 410 and is disposed opposite to the clearance hole 4222. The clearance hole 4222 passes through the baffle plate 422, and the baffle plate 422 surrounds at least a portion of the outer periphery of the clearance hole 4222; the baffle plate 422 overlaps the drawer cover 410.

[0101] After placing the air duct component 420 on top of the drawer cover 410 and inserting the first snap-fit ​​structure 4112 into the clearance hole 4222, the baffle plate 422 overlaps the top of the drawer cover 410. Since the baffle plate 422 is located at the bottom of the air duct plate 421, the baffle plate 422 reduces the gap between the air duct component 420 and the drawer cover 410 along the height direction Z of the inner box 110, making it difficult for cold air in the air duct 4211 to flow into the clearance hole 4222. With the total air volume flowing into the air duct 4211 from the air inlet 4121 remaining unchanged, the amount of air leaking from the clearance hole 4222 is reduced, thereby increasing the amount of air flowing into the storage cavity 301 and improving the cooling effect on the items in the storage drawer 30.

[0102] refer to Figure 7 , Figure 8 and Figure 10 The drawer lid 410 may be configured with an air inlet 4121 and an air outlet 4111. The air inlet 4121 is connected to the air cavity 210, and the air outlet 4111 is connected to the storage cavity 301. The air duct 4211 is connected to both the air inlet 4121 and the air outlet 4111.

[0103] The cold air in the air cavity 210 enters the air guide duct 4211 through the air inlet 4121 and flows into the storage cavity 301 through the air outlet 4111, so as to transport the cold air in the air cavity 210 to the storage cavity 301, thereby lowering the temperature in the storage cavity 301. The low temperature environment is conducive to extending the shelf life of food.

[0104] The partition cover 430 can be closed on the top of the whole consisting of the drawer cover 410 and the air duct component 420, or the partition cover 430 can be closed on the top of the drawer cover 410 and the air duct component 420 respectively.

[0105] refer to Figure 8 The top of the drawer lid 410 may be provided with a first snap-fit ​​structure 4112. (See reference) Figure 11 The duct component 420 may be constructed with a clearance hole 4222, and the first snap-fit ​​structure 4112 passes through the clearance hole 4222. (Reference) Figure 7 , Figure 12 and Figure 13 The bottom of the partition cover 430 can be provided with a second snap-fit ​​structure 4311. The second snap-fit ​​structure 4311 passes through the clearance hole 4222 and snaps with the first snap-fit ​​structure 4112. This not only realizes the snap-fit ​​cooperation between the drawer cover 410 and the partition cover 430, but also fixes the air duct component 420 between the drawer cover 410 and the partition cover 430, shortening the assembly time of the shelf assembly 40 and improving the assembly efficiency of the shelf assembly 40.

[0106] In some possible implementations of the embodiments of this application, reference is made to Figure 13The first snap-fit ​​structure 4112 may include two first connecting arms 4113 that are opposite to each other and spaced apart. The bottom end of the first connecting arm 4113 is connected to the top of the drawer cover 410, and the top ends of the opposite sides of the two first connecting arms 4113 are respectively provided with first stop portions 4114.

[0107] refer to Figure 13 The second snap-fit ​​structure 4311 may include two second connecting arms 4312 that are opposite to each other and spaced apart. The top of the second connecting arm 4312 is connected to the bottom of the partition cover 430, and the bottom of the two second connecting arms 4312 on opposite sides are respectively provided with a second stop part 4313.

[0108] When assembling the drawer cover 410 and the partition cover 430, the air duct component 420 is first placed on top of the drawer cover 410, and the first snap-fit ​​structure 4112 is inserted into the clearance hole 4222. Then, the partition cover 430 is placed above the drawer cover 410, and the second snap-fit ​​structure 4311 is aligned with the clearance hole. Next, the partition cover 430 is moved downward relative to the drawer cover 410. The two second stops 4313 pass downward through the gap between the two first stops 4114 and are respectively aligned with the corresponding first stops 4114. That is, each second stop 4313 has a first stop 4114 above it, and the first stops 4114 stop above the second stops 4313, so that the second stops 4313 are not easy to come out of the gap between the two first stops 4114, thus improving the reliability of the connection between the partition cover 430 and the drawer cover 410.

[0109] In some other possible implementations of the embodiments of this application, the first snap-fit ​​structure 4112 may include two first connecting arms that are opposite to each other and spaced apart. The bottom end of the first connecting arm is connected to the top of the drawer cover 410, and the top ends of the opposite sides of the two first connecting arms are respectively provided with first stop portions.

[0110] The second snap-fit ​​structure 4311 may include two second connecting arms that are opposite to each other and spaced apart. The top of the second connecting arms is connected to the bottom of the partition cover 430, and the bottom of the opposite side of the two second connecting arms is provided with a second stop.

[0111] When assembling the drawer cover 410 and the partition cover 430, the air duct component 420 is first placed on top of the drawer cover 410, and the first snap-fit ​​structure 4112 is inserted into the clearance hole 4222. Then, the partition cover 430 is placed above the drawer cover 410, and the second snap-fit ​​structure 4311 is aligned with the clearance hole. Next, the drawer cover 410 is moved upward relative to the partition cover 430. After the two first stops pass upward through the gap between the two second stops, they are respectively aligned with the corresponding second stops. That is, there is a second stop below each first stop, and the second stops stop below the first stops, so that the first stops are not easy to come out from the gap between the two second stops, thus improving the reliability of the connection between the partition cover 430 and the drawer cover 410.

[0112] In the implementation of the shelf assembly 40 including the partition cover 430, refer to Figure 7 The partition cover 430 may have slides 435 on both sides along the depth direction Y of the box liner 110, and the rear end of the slide 435 passes through the partition cover 430.

[0113] refer to Figure 7 , Figure 14 and Figure 15 The partition cover 430 may include an upper plate 431, and the bottom of the upper plate 431 is provided with a second snap-fit ​​structure 4311.

[0114] refer to Figure 6 , Figure 14 and Figure 15 The partition cover 430 may also include a first side plate 432, the top of which is connected to the bottom of the upper plate 431.

[0115] refer to Figure 6 , Figure 14 and Figure 15 The partition cover 430 may also include a support portion 433, which is disposed on the side of the first side plate 432 facing the gallbladder sidewall 114. The support portion 433 is partially opposite to and spaced apart from the upper plate body 431. The support portion 433, the first side plate 432 and the upper plate body 431 enclose and form a slide 435.

[0116] After the shelf assembly 40 is fixedly installed on the guide rib 115 of the cabinet 110, the upper plate 431 overlaps the top of the guide rib 115, the first side plate 432 stops at the end of the guide rib 115 near the refrigeration compartment 111 along the width direction X, and the support part 433 supports the bottom of the guide rib 115 so that the support part 433, the first side plate 432 and the upper plate 431 enclose to form a slide 435 whose cross-section is approximately matched with the cross-section of the guide rib 115. The slide 435 can slide with the guide rib 115 and limit the possibility of the partition cover 430 swaying relative to the cabinet 110 along the height direction Z and the width direction X, thereby improving the stability of the connection between the shelf assembly 40 and the cabinet 110.

[0117] In some possible implementations of the embodiments of this application, reference is made to Figure 5 The side wall 114 of the bladder may also be constructed with a limiting recess 116 that is recessed away from the refrigeration chamber 111.

[0118] refer to Figure 6 The partition cover 430 may have a third snap-fit ​​structure 434 on both sides along the width direction X. After the shelf assembly 40 and the box liner 110 are assembled, part of the third snap-fit ​​structure 434 is snapped into the limiting recess 116 to further reduce the possibility of the partition cover 430 and shelf assembly 40 swaying relative to the box liner 110 along the height direction Z and width direction X, thereby improving the stability of the connection between the shelf assembly 40 and the box liner 110.

[0119] The limiting recess can be located below the front end of the guide rib 115 so that when the shelf assembly 40 slides along the guide rib 115 to almost completely move into the refrigeration compartment 111, the third locking structure 434 gradually moves into the limiting recess 116, and after the shelf assembly 40 and the guide rib 115 are in place, the third locking structure 434 is completely locked in the limiting recess.

[0120] In some possible implementations of the embodiments of this application, reference is made to Figure 6 The third snap-fit ​​structure 434 may include a third connecting arm 4341 and a third stop portion 4342; the third stop portion 4342 is disposed at one end of the third connecting arm 4341 and is located on the side of the third connecting arm 4341 facing the gallbladder sidewall 114; the end of the third connecting arm 4341 away from the third stop portion 4342 is connected to the sidewall of the partition cover 430.

[0121] When the shelf assembly 40 moves relative to the inner box 110 until the third stop 4342 contacts the inner box side wall 114, as the shelf assembly 40 moves further backward, the inner box side wall 114 gradually squeezes the third stop 4342 and causes the third connecting arm 4341 to deform to a certain extent, so that the third stop 4342 moves away from the inner box side wall 114, so that the shelf assembly 40 can move further backward until the third stop 4342 moves into the limiting recess. At this time, the third connecting arm 4341 resets and the third stop 4342 moves into the limiting recess. Due to the stopping effect of the side wall of the limiting recess on the third stop 4342, the shelf assembly 40 will not be able to continue to move backward. At this time, the shelf assembly 40 and the inner box 110 are assembled in place.

[0122] In some possible implementations of the embodiments of this application, reference is made to Figure 5 The side wall 114 of the bladder can also be constructed with a stop rib 117 protruding toward the refrigeration compartment 111. The stop rib 117 is located behind the guide rib 115. The front side of the stop rib 117 has a stop surface 118. The stop surface 118 is opposite to the rear end of the partition cover 430. The stop surface 118 is used to stop at the rear end of the partition cover 430.

[0123] When the shelf assembly 40 slides backward along the guide rib 115, when the rear end of the partition cover 430 moves to contact the stop surface 118, the partition cover 430 will not be able to continue to move backward due to the stopping effect of the stop surface 118, so as to limit the rear end position of the shelf assembly 40 during installation and reduce the possibility of the shelf assembly 40 colliding with the components (such as the air duct assembly 20) inside the rear of the box liner 110.

[0124] In some possible implementations of the embodiments of this application, reference is made to Figure 7 and Figure 8 The drawer cover 410 may include a lower plate 411, and the top of the lower plate 411 is provided with a first snap-fit ​​structure 4112.

[0125] refer to Figure 6 , Figure 7 and Figure 8 The drawer cover 410 may also include a second side panel 412, the bottom end of which is connected to the top of the lower panel 411. The second side panel 412 may extend along the edge of the lower panel 411 and is engaged with the partition cover 430.

[0126] In one implementation of the partition cover 430 including the first side plate 432, the second side plate 412 may be opposite to the first side plate 432, and the first side plate 432 may surround at least a portion of the exterior of the second side plate 412.

[0127] refer to Figure 7The first side panel 432 may have multiple slots 4321, and the second side panel 412 facing the first side panel 432 may have multiple protrusions 4122. The multiple protrusions 4122 correspond one-to-one with the multiple slots 4321, and each protrusion 4122 is engaged in the corresponding slot 4321 to fix the edges of the drawer cover 410 and the partition cover 430, thereby improving the reliability of the connection between the drawer cover 410 and the partition cover 430.
