Description

Technical Field

[0001] This disclosure relates to the field of household appliance technology, and in particular to a refrigerator drawer assembly and a refrigerator. Background Technology

[0002] Currently, traditional refrigerator drawer designs typically use side rails to secure the drawer and facilitate smooth pulling and pushing. However, in practical applications, this design has some significant shortcomings. First, when the drawer is loaded with a certain weight of food, or when food is placed in different positions within the drawer, the load on different parts of the drawer becomes uneven, causing the drawer to wobble during operation and affecting the smoothness of the movement. This instability not only causes inconvenience but may also accelerate the wear and tear on the rails, reducing the overall lifespan of the refrigerator drawer. Utility Model Content

[0003] The embodiments of this disclosure provide a refrigerator drawer assembly and a refrigerator that enable the refrigerator drawer to be pulled out more smoothly and steadily.

[0004] One aspect of the embodiments of this disclosure provides a refrigerator drawer assembly, comprising:

[0005] The box has a receiving cavity with an opening, and the box includes a first bottom wall;

[0006] The drawer is inserted into a receiving cavity through an opening, and the drawer can be pulled outward or pushed inward in a first direction, and the drawer includes a second bottom wall;

[0021] The first plate is connected to one side of the extension along the second direction; and

[0022] The U-shaped plate has an upward-facing opening and includes two opposing arms and a connecting part. The connecting part connects the two arms, with one arm connected to the end of the first plate away from the extension. The connecting part is embedded in the first through groove.

[0023] In some embodiments, the rear region of the second bottom wall is recessed inward to form a first recessed area, and the second snap-fit ​​assembly includes:

[0024] The second elastic buckle is connected to the rear end of the first sliding guide rail along the first direction and extends obliquely forward; and

[0025] A latching element is disposed on the sidewall of the first recessed area and located in the middle along the second direction. The latching element is embedded below the second elastic buckle and is configured to disengage from the second elastic buckle when subjected to a forward force.

[0026] In some embodiments, the housing further includes a first sidewall connected to the end of the first bottom wall along a second direction, and the second sliding mechanism includes:

[0028] The second sliding guide rail is slidable relative to the second fixed guide rail along the first direction, and the two ends of the second sliding guide rail along the first direction are connected to the drawer.

[0029] In some embodiments, the bottom of the first sidewall is provided with a downwardly extending extension plate, and the area of ​​the second bottom wall adjacent to the extension plate is recessed into the drawer to form a second recessed area. Multiple connecting plates are spaced apart in the second recessed area along a first direction. The connecting plates are connected to the extension plate and the second bottom wall on the sidewall of the second recessed area. Each connecting plate has a groove at its end, and the multiple grooves are configured to guide the movement of the second sliding guide rail.

[0030] In some embodiments, the front end of the second sliding rail along the first direction is detachably connected to the drawer via a third snap-fit ​​assembly, and the rear end of the second sliding rail along the first direction is detachably connected to the drawer via a fourth snap-fit ​​assembly.

[0031] In some embodiments, the bottom of the first sidewall is provided with a downwardly extending extension plate, and the third snap-fit ​​assembly includes:

[0032] A second through slot is provided in the front region of the extension plate along the first direction; and

[0033] The third elastic buckle is connected to the front end of the second sliding guide along the first direction and is located on the side of the second sliding guide facing the first sidewall.

[0038] Based on the above technical solution, the refrigerator drawer assembly of this embodiment provides second sliding mechanisms on the left and right sides where the drawer mates with the cabinet, which are used to provide the main support and guidance for the drawer. A first sliding mechanism is provided in the middle area at the bottom where the drawer mates with the cabinet, which is used to provide auxiliary support and guidance for the drawer. Thus, they can jointly provide guidance for the movement of the drawer, significantly enhance the overall structural stability and support rigidity of the drawer, effectively distribute the load of the drawer, reduce the shaking when pushing and pulling without load and the shaking caused by uneven load, and also improve the shaking caused when the drawer is pulled out into a cantilever state due to insufficient rigidity of the sliding mechanism itself.

[0039] Therefore, when pulling outwards or pushing inwards, the movement is more stable and smooth, reducing the drawer's left-right and up-down swaying, effectively limiting the shaking within the four degrees of freedom, improving the user experience, and extending the service life of the sliding mechanism.

[0061] Based on the embodiments disclosed above, in the absence of explicit denial or conflict, the technical features of one embodiment may be advantageously combined with one or more other embodiments.

[0062] The inventors discovered through research that drawers in current refrigerators suffer from wobbling and poor stability when pulled outwards. The main reason lies in the guide rails on both sides of the drawer. Gaps exist between the fixed and moving parts of these rails, or the rails themselves may lack sufficient rigidity, all of which can cause wobbling. When the drawer is pulled out, the overall structure forms an unstable cantilever, with a longer cantilever resulting in greater travel. The combination of these factors causes the drawer to wobble even when empty. The inherent limitations of the guide rails and the inherent instability of the drawer's cantilever structure result in poor smoothness and stability when pulling the drawer out. Furthermore, this phenomenon becomes more pronounced when the drawer is filled with items of varying weights or when the weight of the items is unevenly distributed.

[0063] To address the aforementioned problems, this disclosure provides a refrigerator drawer assembly, such as... Figures 1 to 9 As shown, in some embodiments, the refrigerator drawer assembly includes:

[0064] The box 1 has a receiving cavity with an opening, and the box 1 includes a first bottom wall 11;

[0065] Drawer 2 is inserted into the receiving cavity through an opening, and drawer 2 can be pulled outward or pushed inward along the first direction x. Drawer 2 includes a second bottom wall 21.

[0066] The first sliding mechanism 3 is connected between the first bottom wall 11 and the second bottom wall 21, and is located in the middle region along the second direction y, which is perpendicular to the first direction x; and

[0067] Two second sliding mechanisms 4 are connected between the drawer 2 and the box 1 and are located on both sides along the second direction y;

[0068] The first sliding mechanism 3 and the two second sliding mechanisms 4 are configured to jointly guide the movement of the drawer 2.

[0069] Specifically, such as Figure 3 As shown, the box 1 includes a first bottom wall 11, a first top wall 12, and two first side walls 13. The first bottom wall 11 and the first top wall 12 are arranged opposite each other along a third direction z (height direction), which is perpendicular to the first direction x (front-back direction) and the second direction y (left-right direction). The two first side walls 13 are respectively connected to the two ends of the first bottom wall 11 and the first top wall 12 along the second direction y. Optionally, the first box 1 may also include a first rear wall 14, with an opening at the front end. For example, the box 1 has a cuboid structure.

[0070] A refrigerator generally has at least one refrigerator compartment and a freezer compartment. One cabinet 1 can be installed in the refrigerator compartment or the freezer compartment, or multiple cabinets 1 can be installed along a third direction z. The first bottom wall 11 and the first top wall 12 of adjacent cabinets 1 can be shared. Optionally, for larger refrigerators, multiple cabinets 1 can also be installed side by side in the second direction y, and adjacent cabinets 1 can share adjacent side walls.

[0071] like Figure 8 As shown, drawer 2 includes a second bottom wall 21, two second side walls 22, a second rear wall 29, and a front wall. The two second side walls 22 are respectively connected to the two ends of the second bottom wall 21 along the second direction y. The second rear wall 29 and the front wall are respectively connected to the rear end and front end of the second bottom wall 21 along the first direction x. The upper part of drawer 2 is open and used to store items such as meat, vegetables, and fruits. Figure 1 This is a diagram showing drawer 2 fully pushed back in. Figure 2 This is a diagram showing drawer 2 in the pulled-out position.

[0072] The first sliding mechanism 3 and the two second sliding mechanisms 4 both extend along the first direction x. The second sliding mechanism 4 can be located between the first bottom wall 11 of the box body 1 and the second bottom wall 21 of the drawer 2 along the second direction y near the side, and / or located between the first side wall 13 of the box body 1 and the second side wall 22 of the drawer 2.

[0073] In this embodiment, second sliding mechanisms 4 are respectively provided on the left and right sides where the drawer 2 mates with the cabinet 1, which provide the main support and guidance for the drawer 2. A first sliding mechanism 3 is provided in the middle area of ​​the bottom where the drawer 2 mates with the cabinet 1, which provides auxiliary support and guidance for the drawer 2. This allows for combined guidance of the drawer 2's movement, significantly enhancing the overall structural stability and support rigidity of the drawer 2, effectively distributing the load on the drawer 2, reducing swaying during unloaded pushing and pulling, and reducing swaying caused by uneven load. It also improves the swaying that occurs when the drawer 2 is pulled out into a cantilevered state due to insufficient rigidity of the sliding mechanism itself. Moreover, the first sliding mechanism 3 is located in the middle area, preventing the drawer 2 from jamming due to tilting during pushing and pulling.

[0074] Therefore, when pulling outwards or pushing inwards, the movement is more stable and smooth, reducing the left-right and up-down swaying of drawer 2, effectively limiting the shaking within four degrees of freedom, improving the user experience, and extending the service life of the sliding mechanism. Specifically, the second sliding mechanisms 4 on both sides are mainly used to limit the vertical movement of drawer 2, and the first sliding mechanism 3 at the bottom is mainly used to limit the horizontal movement of drawer 2.

[0075] In some embodiments, such as Figure 8 As shown, the first sliding mechanism 3 and the two second sliding mechanisms 4 both extend along the first direction x, and the length of the first sliding mechanism 3 is greater than that of the second sliding mechanism 4.

[0076] Since the second sliding mechanism 4 is the main sliding guide mechanism, the first sliding mechanism 3 is designed to be of a larger length, so that the drawer 2 can be pulled out to the maximum stroke designed by the second sliding mechanism 4, making it convenient to take out and put in items.

[0077] In some embodiments, such as Figure 3 , Figure 6 and Figure 7 As shown, the first sliding mechanism 3 includes:

[0078] A first fixed guide rail 31 extends along a first direction x and is fixed to a first bottom wall 11; and

[0079] The first sliding guide rail 32 is slidable relative to the first fixed guide rail 31 along the first direction x, and the two ends of the first sliding guide rail 32 along the first direction x are connected to the drawer 2.

[0080] The first sliding guide rail 32 can cover the first fixed guide rail 31, which increases the width of the first sliding guide rail 32 and provides more stable support for the bottom of the drawer 2. The two ends of the first sliding guide rail 32 can be fixedly connected to the drawer 2, for example, by fasteners, adhesive, or snap fasteners, or the two ends of the first sliding guide rail 32 can be detachably connected to the drawer 2 to facilitate the removal of the drawer 2 for cleaning or placing items.

[0081] The first sliding mechanism 3 in this embodiment includes a first fixed guide rail 31 and a first sliding guide rail 32 that cooperate with each other. The first fixed guide rail 31 is fixed to the box body 1, and the first sliding guide rail 32 is connected to the drawer 2. It can provide support and guidance for the drawer 2 to move along the first direction x, thereby improving the smoothness of the drawer 2's movement. Moreover, both the front and rear ends of the first sliding guide rail 32 are connected to the drawer 2, which can improve the reliability of the connection and prevent the drawer 2 from detaching from the first sliding guide rail 32, thus preventing it from being pulled out normally.

[0082] In some embodiments, such as Figure 8 As shown, the bottom surface of the second bottom wall 21 is provided with two limiting members 27 in the middle area along the second direction y. Both limiting members 27 extend along the first direction x and are spaced apart along the second direction y. The first sliding guide rail 32 is located in the area between the two limiting members 27. The limiting members 27 are configured to provide guidance for the movement of the first sliding guide rail 32.

[0083] The limiting member 27 can be elongated, and to reduce weight, its cross-section is L-shaped. One plate of the L-shaped structure is connected to the second bottom wall 21, and the other plates of each of the two L-shaped structures are arranged opposite each other along the second direction y. To improve the rigidity of the limiting member 27, multiple reinforcing plates 271 are spaced apart along the first direction x within the area enclosed by the L-shaped structures. The two sides of the first sliding guide rail 32 can cooperate with the two limiting members 27.

[0084] For example, such as Figure 3 As shown, the first sliding guide rail 32 includes two side plates 321 and multiple connecting plates 322. The two side plates 321 extend along the first direction x and are spaced apart along the second direction y. The multiple connecting plates 322 are spaced apart along the first direction x and connected between the two side plates 321. The connecting plates 322 can be set horizontally or vertically, which can ensure the overall rigidity of the first sliding guide rail 32 and reduce weight.

[0085] like Figure 6 As shown, the first fixed guide rail 31 may include a U-shaped bracket 311, a support frame 312, and a guide rail portion 313. The opening of the U-shaped bracket 311 faces upward, and its bottom is fixed to the first bottom wall 11. The support frame 312 may have a Y-shaped structure, and its bottom is fixed to the middle area along the second direction y inside the U-shaped bracket 311. The guide rail portion 313 has an inverted U-shaped structure, which is fastened and fixed to the top of the support frame 312. The first sliding guide rail 32 is supported on the guide rail portion 313 and can slide relative to the guide rail portion 313.

[0086] This embodiment provides guidance for the movement of the first sliding guide rail 32 by setting two limiting members 27 at the bottom of the drawer 2. By reducing the fit gap, it can play a limiting role in the left and right directions, thereby making the movement of the drawer 2 more stable and reducing left and right wobbling.

[0087] In some embodiments, the opposing surfaces of the two limiting members 27 are both inclined surfaces, and the distance between the two inclined surfaces gradually increases from the surface of the second bottom wall 21 outwards. The two sides of the first sliding guide rail 32 respectively cooperate with the two inclined surfaces.

[0088] Among them, the inclined surfaces of the two limiting members 27 gradually increase in distance from the surface of the second bottom wall 21 to the outside, forming an open trapezoidal receiving space. Correspondingly, the two sides of the first sliding guide rail 32 can also be set as planes, and the dimensions of the two sides of the first sliding guide rail 32 gradually decrease from the bottom to the top, forming a trapezoidal cross-section.

[0089] This embodiment designs the two limiting members 27 and the first sliding guide rail 32 in a trapezoidal fit. On the one hand, the inclined surface of the side of the first sliding guide rail 32 provides better support for the limiting members 27, thus providing better support and guidance for the movement of the drawer 2. On the other hand, since the accommodating space of the two limiting members 27 into the first sliding guide rail 32 is relatively large at the opening, it can play a guiding role during installation. Even if the fit is located at the bottom and there are deviations in the machining accuracy, it can still be installed smoothly. Furthermore, under the weight of the drawer 2 and the contents inside, the inclined fit helps to eliminate gaps after assembly, thereby enabling the first sliding mechanism 3 to provide better support and guidance for the drawer 2 in the middle area, making the movement of the drawer 2 more stable.

[0090] In some embodiments, the front end of the first sliding guide rail 32 along the first direction x is detachably connected to the second bottom wall 21 via a first snap-fit ​​assembly, and the rear end of the first sliding guide rail 32 along the first direction x is detachably connected to the second bottom wall 21 via a second snap-fit ​​assembly. Alternatively, only the front end or the rear end may be connected.

[0091] In this embodiment, both the front and rear ends of the first sliding guide rail 32 are detachably connected to the second bottom wall 21 of the drawer 2. This not only improves the reliability of the connection between the drawer 2 and the first sliding guide rail 32, but also allows the drawer 2 to be easily removed when it is necessary to clean or neatly move items, thus improving the reliability of disassembly and assembly.

[0092] In some embodiments, such as Figure 3 , Figure 4 and Figure 8 As shown, the first snap-fit ​​assembly includes:

[0093] Two protruding plates 28 are disposed in the front middle region of the bottom surface of the second bottom wall 21 and spaced apart along the second direction y. The protruding plates 28 extend along the first direction x and are provided with a first through groove 281.

[0094] Two first elastic buckles 34 are connected to the front end of the first sliding guide rail 32 along the first direction x, and are located on both sides of the first sliding guide rail 32 along the second direction y. The first elastic buckles 34 are embedded in the first through groove 281 on the same side, and the two first elastic buckles 34 are configured to disengage from the two first through grooves 281 respectively when subjected to a relatively inward force.

[0095] Among them, such as Figure 8 As shown, two protruding plates 28 are located in the area at the front end of the two limiting members 27, and the first through groove 281 can be a rectangular groove, etc. Figure 3 and Figure 4 As shown, the second sliding mechanism 4 has an extension 33 at its front end along the first direction x, which can be in the form of a plate. Two first elastic buckles 34 are connected to the two sides of the extension 33 along the second direction y.

[0096] This embodiment provides first elastic buckles 34 on both sides of the front end of the first sliding guide rail 32. When the first sliding guide rail 32 is fixed to the drawer 2, the first elastic buckles 34 can be engaged with the first through groove 281 to reliably connect the first sliding guide rail 32 and the drawer 2. Furthermore, when the drawer 2 needs to be disassembled, the user can apply an inward and downward force to the first elastic buckles 34 on both sides, causing them to deform and disengage from the first through groove 281, thus facilitating the removal of the drawer 2. Moreover, by providing first elastic buckles 34 on both sides of the front end of the first sliding guide rail 32, the drawer 2 can be reliably fixed. When disassembly is required, the user can easily apply relative force, which is less strenuous and convenient, making the disassembly of the drawer 2 quick and easy.

[0097] In some embodiments, such as Figure 3 and Figure 4 As shown, the second sliding mechanism 4 has an extension 33 at its front end along the first direction x, and the first elastic buckle 34 includes:

[0098] The first plate 341 is connected to one side of the extension 33 along the second direction y; and

[0099] The U-shaped plate has an upward-facing opening and includes two opposing arms 343 and a connecting portion 342. The connecting portion 342 connects the two arms 343, and one of the arms 343 is connected to the end of the first plate 341 away from the extension 33. The connecting portion 342 is embedded in the first through groove 281.

[0100] The first plate 341 is horizontally positioned, connected to the extension 33 on one side along the second direction y and higher than the extension 33, to facilitate the elastic deformation of the first elastic buckle 34. One arm 343 of the U-shaped plate is connected to the end of the first plate 341 away from the extension 33 along the second direction y and extends vertically downward. A protrusion 344 may be provided on the surface of this arm 343 facing the inner side of the U-shaped plate to abut against the side wall of the protruding plate 28 and reduce the wobbling of the first elastic buckle 34 within the first through groove 281. The connecting portion 342 of the U-shaped plate may be horizontally positioned, and the other arm 343 of the U-shaped plate extends upward, with its free end slightly retracted inward at a preset angle to restrict the first elastic buckle 34 from disengaging from the first through groove 281.

[0101] The first elastic buckle 34 in this embodiment can achieve greater elasticity through structural design. Through the design of the bending part, the first elastic buckle 34 can be easily inserted into the first through groove 281 to achieve a reliable fixation of the drawer 2, and the first elastic buckle 34 can be easily disengaged from the first through groove 281 when disassembly is required, making disassembly convenient.

[0102] In some embodiments, such as Figure 5 and Figure 9 As shown, the rear region of the second bottom wall 21 is recessed inward to form a first recessed area, and the second snap-fit ​​assembly includes:

[0103] The second elastic buckle 35 is connected to the rear end of the first sliding guide rail 32 along the first direction x, and extends obliquely forward; and

[0104] The engaging member 30 is located on the side wall of the first recessed area and in the middle position along the second direction y. The engaging member 30 is embedded below the second elastic buckle 35 and is configured to disengage from the second elastic buckle 35 when subjected to a forward force.

[0105] Among them, such as Figure 5 As shown, the second elastic buckle 35 is located at the rear end of the first sliding guide rail 32 and extends obliquely forward from the top position to form an opening for the insertion of the engaging member 30. The rear region of the second bottom wall 21 can be recessed inward over its entire width, and the engaging member 30 is provided on the side wall of the first recessed area along the first direction x. The engaging member 30 can be a protruding sheet-like structure.

[0106] In this embodiment, the second latching assembly, when fixing the drawer 2, has the engaging member 30 inserted from the front under the second elastic latch 35 to achieve a locking and fixing with the second elastic latch 35. When it is necessary to disassemble the drawer 2, after the first latching assembly at the front end is released, the drawer 2 is pulled forward slightly to allow the engaging member 30 to move out from under the second elastic latch 35, thereby releasing the fixation on the drawer 2. This second latching assembly has a simple structure, which can not only reliably fix the drawer 2 together with the first latching assembly, but also allows for quick disassembly.

[0107] In some embodiments, such as Figure 3 and Figure 7 As shown, the box body 1 is provided with second sliding mechanisms 4 on both the left and right sides along the second direction y. The box body 1 also includes a first side wall 13 connected to the end of the first bottom wall 11 along the second direction y. The second sliding mechanism 4 includes:

[0108] The second fixed guide rail 41 extends along the first direction x and is fixed in the area between the first bottom wall 11 and the first side wall 13; and

[0109] The second sliding guide rail 42 is slidable relative to the second fixed guide rail 41 along the first direction x, and the two ends of the second sliding guide rail 42 along the first direction x are connected to the drawer 2.

[0110] The housing 1 has a mounting bracket 43 in the area between the first bottom wall 11 and the first side wall 13. For example, it is L-shaped. The mounting bracket 43 can be fixed to the first bottom wall 11 and the first side wall 13 by fasteners such as screws. The second fixed guide rail 41 can be fixed to the mounting bracket 43 by fasteners such as screws. The second sliding guide rail 42 is located above the second fixed guide rail 41.

[0111] A stop 45 can be fixedly installed at the front end of the second sliding guide rail 42 to block the end face of the second sliding guide rail 42 that mates with the second fixed guide rail 41.

[0112] The second sliding mechanism 4 in this embodiment includes a second fixed guide rail 41 and a second sliding guide rail 42 that cooperate with each other. The second fixed guide rail 41 is fixed to the housing 1, and the second sliding guide rail 42 is connected to the drawer 2. It can provide support and guidance for the drawer 2 to move along the first direction x, thereby improving the smoothness of the drawer 2's movement. Moreover, both the front and rear ends of the second sliding guide rail 42 are connected to the drawer 2, which can improve the reliability of the connection and prevent the drawer 2 from detaching from the second sliding guide rail 42, thus preventing it from being pulled out normally.

[0113] In some embodiments, such as Figure 8 and Figure 9 The bottom of the first sidewall 13 is provided with a downwardly extending extension plate 23. The area of ​​the second bottom wall 21 adjacent to the extension plate 23 is recessed into the drawer 2 to form a second recessed area. Multiple connecting plates 24 are arranged at intervals along the first direction x in the second recessed area. The connecting plates 24 are connected to the extension plate 23 and the second bottom wall 21 on the sidewall of the second recessed area. Each connecting plate 24 has a groove 241 at its end. The multiple grooves 241 are aligned along the first direction x and are configured to guide the movement of the second sliding guide rail 42.

[0114] This embodiment provides guidance for the movement of the second sliding guide rail 42 by setting multiple grooves 241 on both sides of the drawer 2. By reducing the fit gap, it can play a limiting role in the left and right directions, thereby making the movement of the drawer 2 more stable and reducing left and right wobbling.

[0115] In some embodiments, the front end of the second sliding guide rail 42 along the first direction x is detachably connected to the drawer 2 via a third snap-fit ​​assembly, and the rear end of the second sliding guide rail 42 along the first direction x is detachably connected to the drawer 2 via a fourth snap-fit ​​assembly. Alternatively, it may be connected only at the front end or the rear end.

[0116] In this embodiment, both the front and rear ends of the second sliding guide rail 42 are detachably connected to the second bottom wall 21 of the drawer 2. This not only improves the reliability of the connection between the drawer 2 and the second sliding guide rail 42, but also allows the drawer 2 to be easily removed when it is necessary to clean or neatly move items, thus improving the reliability of disassembly and assembly.

[0117] In some embodiments, such as Figure 8 As shown, the bottom of the first sidewall 13 is provided with a downwardly extending extension plate 23, and the third snap-fit ​​assembly includes:

[0118] The second through slot 25 is provided in the front region of the extension plate 23 along the first direction x; and

[0119] The third elastic buckle 44 is connected to the front end of the second sliding guide rail 42 along the first direction x, and is located on the side of the second sliding guide rail 42 facing the first sidewall 13. The third elastic buckle 44 is embedded in the second through groove 25, and the third elastic buckle 44 is configured to disengage from the two second through grooves 25 when subjected to an inward force.

[0120] The second through slot 25 is located on the front side of the foremost connecting plate 24, and the third elastic buckle 44 can be located on the front end of the second sliding guide rail 42 facing the first side wall 13, for example, in a triangular shape, to facilitate embedding into the second through slot 25.

[0121] In this embodiment, the third snap-fit ​​mechanism, when securing drawer 2, involves the third elastic snap-fit ​​44 inserting into the second through groove 25 from the side to achieve a locking and securing action. When drawer 2 needs to be disassembled, pressing the third elastic snap-fit ​​44 inward from the side disengages it from the second through groove 25, thereby releasing the drawer 2 from its fixation. This second snap-fit ​​assembly has a simple structure, achieving both reliable fixation of drawer 2 and quick disassembly.

[0122] In some embodiments, such as Figure 8 As shown, the bottom of the first sidewall 13 is provided with a downwardly extending extension plate 23, and the area of ​​the second bottom wall 21 adjacent to the extension plate 23 is recessed into the drawer 2 to form a second recessed area. The fourth latching assembly includes:

[0123] Connecting buckle 26, disposed within the second recessed area and connected to the extension plate 23 and the second bottom wall 21 on the side wall of the second recessed area; and

[0124] The fourth elastic buckle 46 is connected to the top of the rear end of the second sliding guide rail 42 along the first direction x. The fourth elastic buckle 46 extends obliquely forward and engages with the connecting buckle 26, and is configured to disengage from the connecting buckle 26 when subjected to a forward force.

[0125] The connecting buckle 26 may be plate-shaped and connected between the extension plate 23 and the sidewall of the second recessed area.

[0126] In this embodiment, the fourth snap-fit ​​assembly, when fixing the drawer 2, has a fourth elastic snap-fit ​​46 that engages with the connecting snap-fit ​​26 from the rear, between the connecting snap-fit ​​26 and the second recessed area. When it is necessary to disassemble the drawer 2, after the third snap-fit ​​assembly at the front is released, the drawer 2 is pulled forward slightly, allowing the fourth elastic snap-fit ​​46 to move out from between the connecting snap-fit ​​26 and the second recessed area, thereby releasing the drawer 2 from its fixation. This fourth snap-fit ​​assembly has a simple structure, which can reliably fix the drawer 2 together with the third snap-fit ​​assembly, and also allows for quick disassembly.

[0127] In the above embodiments of this disclosure, since there are gaps between the buckles and gaps in the guide rail fit, by setting a limiting structure, such as a groove 241 and a limiting member 27, at the bottom of the drawer 2, the movement of the drawer 2 can be limited, minimizing the limitation and thus reducing the shaking when pulling out.

[0128] Sliding mechanisms are installed on the bottom and sides of drawer 2. This effectively restrains the wobbling of drawer 2 in the up-down and left-right directions. This is because: when drawer 2 is pulled out, the lever arm of the second sliding mechanism 4 (e.g., guide rail) installed on the left and right sides gradually increases along the direction of drawer 2's extension, but the lever arm of the second sliding mechanism 4 in the up-down direction remains unchanged, still being half of the cross-section of the second sliding mechanism 4. Therefore, the weak point of the second sliding mechanism 4 installed on the left and right sides is in the direction perpendicular to the lever arm (i.e., the force when the user shakes the drawer left and right). Thus, the second sliding mechanism 4 installed on the left and right sides can effectively restrict the up-down wobbling of drawer 2, but it is difficult to restrict the left-right wobbling of drawer 2. Similarly, the first sliding mechanism 3 (e.g., guide rail) installed at the bottom of drawer 2 can effectively restrict the up-left-right wobbling of drawer 2, but it is difficult to restrict the up-down wobbling of drawer 2.

[0129] Secondly, this disclosure provides a refrigerator, including the refrigerator assembly of the above embodiments. The refrigerator assembly is disposed in the refrigerator compartment and / or freezer compartment of the refrigerator.

[0130] In this refrigerator embodiment, second sliding mechanisms 4 are respectively provided on the left and right sides where the drawer 2 mates with the cabinet 1, serving as the main support and guide for the drawer 2. A first sliding mechanism 3 is provided in the middle area of ​​the bottom where the drawer 2 mates with the cabinet 1, serving as the auxiliary support and guide for the drawer 2. These mechanisms work together to guide the movement of the drawer 2, significantly enhancing the overall structural stability and support rigidity of the drawer 2, effectively distributing the load on the drawer 2, reducing swaying when pushed and pulled out without load, and reducing swaying caused by uneven load. They also improve the swaying that occurs when the drawer 2 is pulled out into a cantilevered state due to insufficient rigidity of the sliding mechanism itself. Furthermore, the first sliding mechanism 3 is located in the middle area to prevent the drawer 2 from jamming due to tilting during pushing and pulling.

[0131] Therefore, when pulling outward or pushing inward, the movement is more stable and smooth, reducing the left-right and up-down swaying of drawer 2, effectively limiting the shaking within the four degrees of freedom, improving the user experience during use, and extending the service life of the sliding mechanism.

The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this disclosure. It should be noted that those skilled in the art can make various improvements and modifications to this disclosure without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this disclosure.
