Description

Technical Field

[0001] This application relates to the field of refrigerator technology, and in particular to a drawer cabinet and a refrigerator. Background Technology

[0002] A certain gap needs to be maintained between the refrigerator body and the door to install the door seal, thus achieving a sealing and heat insulation effect. If the door gap is too large, the refrigerator door will often not close tightly, causing cold leakage, increased energy consumption, and condensation to easily form between the doors, affecting the user experience. However, the connection structure between the refrigerator door and the body consists of multiple components. Due to manufacturing and assembly errors, even if the dimensions of each component are correct and the assembly is accurate, it is still possible to avoid a large door gap. Due to its own weight, the larger gap in the refrigerator drawer doors often appears at the top of the door, creating a gap difference between the top and bottom. Summary of the Invention

[0003] This application provides a drawer cabinet, and this application also provides a refrigerator having the above-described drawer cabinet.

[0004] In a first aspect, this application provides a drawer cabinet for use in the storage space of a refrigerator's cabinet. The drawer cabinet includes a door, a guide rail bracket, a connector, and an elastic element. The door is used to close the storage space; the guide rail bracket is connected to the door and is adapted to slidably engage with the cabinet. The connector is relatively fixedly disposed on the door; the connector has a limiting part located on the side of the door facing the guide rail bracket and movably limited to the guide rail bracket to form a rotation fulcrum together with the guide rail bracket. The elastic element is located between the guide rail bracket and the door, and the elastic element is in a state of elastic potential energy to exert a force on the guide rail bracket and the door. When the drawer cabinet is installed in the cabinet, the elastic element and the rotation fulcrum are spaced apart in the direction of gravity.

[0005] Secondly, this application also provides a refrigerator, including a cabinet and the aforementioned drawer cabinet, the drawer cabinet being slidably disposed within the cabinet.

[0006] Compared to existing technologies, the drawer cabinet provided in this application uses an elastic element that possesses elastic potential energy to exert a force on the guide rail bracket and the door. When the drawer cabinet is installed in the cabinet body, the elastic element and the rotation fulcrum are spaced apart in the direction of gravity. If the gap between the door and the cabinet body shows a tendency to be larger at the top and smaller at the bottom, the door body tends to tilt relative to the cabinet body, increasing the force on the elastic element. Therefore, the elastic element provides a larger reaction force to the door body, causing the door body to align around the rotation fulcrum and fit against the cabinet body, thereby achieving adaptive adjustment of the door body's posture and ensuring the uniformity of the gap between the door body and the cabinet body.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0019] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. The specification and claims do not distinguish components based on differences in name, but rather on differences in function. For example, the term "comprising" used throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to"; "generally" means that those skilled in the art can solve the technical problem and basically achieve the technical effect within a certain margin of error.

[0020] Please see Figure 1 This application provides a refrigerator 200. This specification does not limit the specific type of refrigerator 200. For example, refrigerator 200 can be a side-by-side refrigerator, a three-door refrigerator, or a French door refrigerator. In this embodiment, refrigerator 200 is a French door refrigerator. A French door refrigerator is generally a vertical refrigerator with a refrigerated upper section and one or more freezer drawers at the bottom.

[0021] Please also refer to Figure 1 and Figure 2In this embodiment, the refrigerator 200 includes a cabinet 201, a refrigerator door 202, and the aforementioned drawer cabinet 100. In some application examples, when the refrigerator 200 is in use, the cabinet 201 is placed upright on a horizontal platform (e.g., a floor). When a user takes items from the refrigerator 200, the side of the cabinet 201 facing the user is designated as the mounting surface 2012. The cabinet 201 has internal partitions that divide the space into multiple storage spaces 2016, which may include: a regular refrigerator space, a 0-degree refrigerator space, a freezer space, etc. The refrigerator door 202 is rotatably connected to the cabinet 201, and when closed relative to the cabinet 201, it partially overlaps the mounting surface 2012. The drawer cabinet 100 is embedded within the storage spaces 2016 and slidably connected to the cabinet 201.

[0022] In the description of this application, it should be understood that the terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "inside", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the purpose of simplifying the description of this application and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0023] Furthermore, unless otherwise explicitly specified or limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or merely surface contact. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] Please also refer to Figure 2 and Figure 3 In this embodiment, the drawer cabinet 100 may include a door 10 and a guide rail bracket 30. The guide rail bracket 30 is slidably disposed on the cabinet body 201 (e.g., Figure 1 As shown, the door 10 is connected to one end of the guide rail bracket 30 and encloses the storage space 2016.

[0025] The guide rail bracket 30 is connected to the door body 10 and the box body 201 (e.g.) Figure 1As shown, the guide rail bracket 30 includes a guide rail portion 32 and a first mounting plate 34. When the drawer cabinet 100 is closed relative to the cabinet body 201, the guide rail portion 32 is located within the storage space 2016. The guide rail portion 32 extends along the depth direction of the storage space 2016 and is slidably connected to the cabinet body 201. This specification does not limit the connection structure between the guide rail portion 32 and the cabinet body 201. For example, the storage space 2016 may be provided with a mounting rail (not shown in the figure), which is fixed to the side wall of the storage space 2016. The guide rail portion 32 and the mounting rail are slidably nested together, or the guide rail portion 32 is connected to a roller, which slides with the mounting rail.

[0026] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] Please also refer to Figure 1 , Figure 3 and Figure 4 The first mounting plate 34 is fixedly connected to one end of the guide rail 32 near the door body 10, and is used to mount the door body 10. The first mounting plate 34 is arranged approximately parallel to the mounting surface 2012. This specification does not limit the connection method between the first mounting plate 34 and the guide rail 32. For example, the first mounting plate 34 can be welded to the guide rail 32, or the first mounting plate 34 can be integrally formed into the guide rail 32.

[0028] In this embodiment, the drawer cabinet 100 may further include a storage box (not shown in the figure), which is connected to the guide rail 32 and located on the side of the door 10 near the guide rail bracket 30. The top of the storage box may be open to facilitate user access to items. Here, "the top of the storage box" refers to the side of the storage box near the refrigerator door 202 when the refrigerator 200 is in use. In use, the user pulls the guide rail bracket 30 through the door 10, causing the storage box to slide out of the storage space 2016, exposing the opening of the storage box outside the cabinet 201, allowing the user to access items.

[0029] To improve the stability of the drawer cabinet 100 sliding relative to the cabinet body 201, in this embodiment, two guide rail brackets 30 are provided. The two guide rail brackets 30 are respectively arranged on opposite sides of the storage space 2016, and the aforementioned storage box can be arranged between the guide rail portions 32 of the two guide rail brackets 30. The two first mounting plates 34 of the two guide rail brackets 30 are respectively connected to opposite sides of the door body 10.

[0030] Please also refer to Figure 4 and Figure 5 In this embodiment, the door 10 is connected to the first mounting plate 34, which is used to enclose the storage space 2016 (e.g., Figure 1 (As shown), to prevent cold leakage from the refrigerator 200. The door 10 may include a door shell 12 and an insulation layer 14 disposed within the door shell 12. The door shell 12 includes an outer shell 121 and an inner liner 123. The outer shell 121 serves as the external surface of the door 10 and is generally a shell-shaped structure with one open side. The opening of the outer shell 121 faces the guide rail bracket 30. The inner liner 123 is fixedly connected to the opening of the outer shell 121 to seal the space inside the outer shell 121. The insulation layer 14 is disposed between the outer shell 121 and the inner liner 123 to isolate the heat conduction between the space inside the refrigerator 201 and the space outside the refrigerator 201, and also to achieve the effect of heat preservation and energy saving. This specification does not limit the specific material of the insulation layer 14. For example, the insulation layer 14 may be made of glass wool or polyurethane foam. In this embodiment, the insulation layer 14 is polyurethane foam.

[0031] Please also refer to Figures 4 to 6 In some embodiments, the door 10 further includes a door seal 16 and a buffer pad 18. The door seal 16 is connected to the inner liner 123 and is arranged circumferentially around the inner liner 123 to improve the sealing performance of the refrigerator 200. The door seal 16 includes a sealing portion 161 and a connecting portion 163. The sealing portion 161 is generally square and annular, and fits against the side of the inner liner 123 opposite to the outer shell 121, covering the connection between the inner liner 123 and the outer shell 121. The connecting portion 163 is connected to the side of the sealing portion 161 facing the inner liner 123 and is embedded in the inner liner 123. The inner liner 123 is provided with a limiting groove 125 for accommodating the connecting portion 163, and a limiting protrusion 165 is provided at the end of the connecting portion 163 away from the sealing portion 161. The limiting protrusion 165 is located on one side of the connecting portion 163 and protrudes relative to the side wall of the connecting portion 163. The bottom dimension of the limiting groove 125 is larger than the opening dimension, and the limiting protrusion 165 is embedded in the bottom of the limiting groove 125, which improves the stability of the door seal 16 connection.

[0032] Please refer to it again. Figure 4 and Figure 5 Four buffer pads 18 are provided, and the four buffer pads 18 are respectively located at the four corners of the inner liner 123 and within the annular space of the door seal 16. The buffer pads 18 are made of an elastic material, such as intersecting. When the door 10 is closed relative to the housing 201, the buffer pads 18 abut against the door 10 and the mounting surface 2012. The buffer pads 18 are used to protect the housing 201 and the door 10 when the door 10 is closed relative to the housing 201.

[0033] It should be understood that the phrase "an element abuts against another element" in this specification means that the two elements can abut against each other in direct contact or indirectly (e.g., when there is an intervening element between them). For example, if the other element is mounted on the intervening element, the first element can abut against the intervening element, thereby "abutting against the other element".

[0034] In this embodiment, the drawer cabinet 100 may further include a connector 40, which is fixedly connected to the door body 10 and is used to connect the door body 10 and the first mounting plate 34. The connector 40 includes a mounting portion 41, which is fixedly disposed within the door shell 12 and embedded within the insulation layer 14. Specifically, the mounting portion 41 includes a connecting plate 412 and a second mounting plate 414. The second mounting plate 414 is disposed near the inner liner 123 and is approximately parallel to the inner liner 123. The connecting plate 412 is connected between the second mounting plate 414 and the inner wall of the outer shell 121. There are two connecting plates 412, which are respectively connected to opposite sides of the second mounting plate 414, and the opposite ends of the two connecting plates 412 are respectively connected to opposite inner side walls of the outer shell 121.

[0035] Please also refer to Figure 4 and Figure 7 The door body 10 also includes a first latching part 11 and a second latching part 13, which are respectively disposed on the inner wall of the outer shell 121 and located at opposite ends of the outer shell 121. The first latching part 11 is formed on the inner wall of the outer shell 121 and protrudes relative to the inner wall of the outer shell 121, and extends along the height direction of the door body 10. Two connecting plates 412 are respectively connected between the first latching part 11 and the second mounting plate 414, and between the second latching part 13 and the second mounting plate 414.

[0036] Taking the connecting plate 412 connected between the first latching part 11 and the second mounting plate 414 as an example, the connecting plate 412 is inclined relative to the second mounting plate 414. The distance between the end of the connecting plate 412 connected to the second mounting plate 414 and the inner liner 123 is less than the distance between the end of the connecting plate 412 connected to the first latching part 11 and the inner liner 123. The end of the connecting plate 412 near the first latching part 11 is provided with a bent end 413 and a limiting protrusion 415. The bent end 413 is bent away from the inner liner 123 relative to the connecting plate 412, so as to be spaced apart from the inner wall of the outer shell 121 where the first latching part 11 is provided. The extension direction of the bent end 413 intersects with the extension direction of the first buckle part 11. The limiting protrusion 415 is provided on the side of the bent end 413 near the first buckle part 11 and protrudes relative to the side wall of the bent end 413. The limiting protrusion 415 abuts against the side of the first buckle part 11 away from the inner liner 123.

[0037] In this embodiment, the second latching part 13 and the first latching part 11 have the same structure. The mating structure between the connecting plate 413 and the second latching part 13, the mating structure between the connecting plate 413 and the first latching part 11, and the arrangement about the center line connecting the first latching part 11 and the second latching part 13 are approximately symmetrical, and will not be described in detail here. The engaging structure between the two connecting plates 412 and the first latching part 11 and the second latching part 13 facilitates the installation of the connector 40 and improves the stability of the second mounting plate 414. The mounting part 41 extends from one end of the inner wall of the outer shell 121 to the other end of the outer shell 121, providing high support capacity and enhancing the deformation resistance of the mounting part 41.

[0038] Please refer to it again. Figure 4 and Figure 5 The connector 40 also includes a limiting part 43, which is connected to the second mounting plate 414 and partially located on the side of the inner liner 123 near the guide rail bracket 30. The limiting part 43 is movably limited to the first mounting plate 34 to form a rotation fulcrum O together with the first mounting plate 34. To facilitate the connection of the limiting part 43 to the inner liner 123 and the first mounting plate 34, the inner liner 123 is provided with a clearance opening 127. The clearance opening 127 extends through the inner liner 123 along the length of the guide rail part 32 to expose part of the second mounting plate 414 outside the door shell 12. The clearance opening 127 is generally a rounded rectangular hole.

[0039] In this embodiment, one end of the limiting part 43 is fixedly connected to the side of the second mounting plate 414 near the inner liner 123, and the other end protrudes through the relief opening 127 out of the inner liner 123 and is exposed outside the door shell 12, and is bent relative to the second mounting plate 414 to form a limiting opening 432. The limiting part 43 is engaged with the first mounting plate 34 through the limiting opening 432. The opening of the limiting opening 432 faces downward, that is, in the refrigerator 200 (e.g. Figure 1 When in use (as shown), the opening of the limiting port 432 faces the side of the refrigerator 200 closest to the platform surface on which it is placed. The limiting part 43 engages with the top of the first mounting plate 34 via the limiting port 432 (when the refrigerator 200 is in use, the first mounting plate 34 is away from the platform surface on which the refrigerator 200 is placed). The door 10 is mounted on the first mounting plate 34 via the limiting part 43, and the door 10 can rotate slightly relative to the first mounting plate 34 based on the rotation fulcrum O. The contact point between the top of the first mounting plate 34 and the inner wall of the limiting port 432 is the aforementioned rotation fulcrum O, and the door 10 can rotate around this rotation fulcrum O, with its rotation axis direction approximately parallel to the width direction of the cabinet 201.

[0040] To improve the stability of the door 10 rotating around the pivot point O, in this embodiment, the drawer cabinet 100 further includes a support pad 50 disposed between the limiting part 43 and the first mounting plate 34. The pivot point O is the contact point between the support pad 50 and the inner wall of the limiting opening 432. The support pad 50 is fixedly connected to the top of the first mounting plate 34. The support pad 50 is generally arched, engaging with the top of the first mounting plate 34 and embedded in the limiting opening 432. The support pad 50 is made of a material with elastic deformation capability. This specification does not limit the specific material; for example, the support pad 50 can be made of rubber or sponge. The side of the support pad 50 near the bottom of the limiting opening 432 is arc-shaped, improving the smoothness of rotation between the limiting part 43 and the support pad 50.

[0041] Please also refer to Figure 4 and Figure 8 In this embodiment, the drawer cabinet 100 further includes an elastic element 60, which is disposed between the first mounting plate 34 and the inner liner 123, forming a flexible connection structure between the door 10 and the guide rail bracket 30. The elastic element 60 is in a state of elastic potential energy to exert a force on the first mounting plate 34 and the door 10. The drawer cabinet 100 is mounted on the box body 201 (e.g., Figure 1 In the state shown, the elastic element 60 and the rotation fulcrum O are spaced apart in the direction of gravity G. The force exerted by the elastic element 60 on the first mounting plate 34 and the door 10, together with the pulling force of the guide rail bracket 30 on the door 10 when the drawer cabinet 100 is closed relative to the cabinet 201, drives the door 10 to rotate slightly around the rotation fulcrum O.

[0042] This specification does not limit the arrangement order of the elastic element 60 and the pivot point O in the direction of gravity G. For example, the pivot point O and the elastic element 60 can be arranged alternately along the direction of gravity G, that is, the pivot point O is above the elastic element 60 (when the refrigerator 200 is in use, the elastic element 60 is on the side away from the horizontal platform on which the refrigerator 200 is placed). When the refrigerator 200 is in normal use, the aforementioned "direction of gravity G" is approximately parallel to the direction from the top to the bottom of the refrigerator 200. In this embodiment, the elastic element 60 is in an elastically compressed state, and the elastic element 60 abuts against the first mounting plate 34 and the second mounting plate 414. This specification does not limit the specific structure of the elastic element 60. The elastic element 60 can be a compression spring, coil spring, or spring sheet structure in an elastically compressed state. In this embodiment, the elastic element 60 is a compression spring.

[0043] It should be understood that the phrase "spaced apart in the direction of gravity" for the two components described in this specification should be broadly interpreted as meaning that the two components are spaced apart in the vertical direction, rather than strictly limiting the two components to be linearly arranged along the direction of gravity. For example, the phrase "spaced apart in the direction of gravity" or "the elastic element is located below the rotation fulcrum O along the direction of gravity" can be exemplified by: the rotation fulcrum O and the elastic element 60 being linearly arranged along the direction of gravity (e.g., ...). Figure 3 As shown), for example, when projected along the direction of gravity, the projections of the two have overlapping portions, so that... Figure 3 The orientation in the text is for descriptive reference. The elastic element 60 can be located directly below the pivot point O; or, the pivot point O and the elastic element 60 do not need to be linearly arranged along the direction of gravity, but are offset along the direction of gravity, and are not set on the same horizontal plane. When projected along the direction of gravity, their projections have overlapping parts or there is a certain gap between their projections. From a macroscopic perspective, with Figure 3 The orientation in the text is for descriptive reference. The elastic element 60 can be located to the lower left or lower right of the rotation fulcrum O.

[0044] To improve the stability of the elastic member 60 during installation, in this embodiment, the second mounting plate 414 is further provided with a first mounting hole 416. The second mounting plate 414 is recessed towards the door shell 12 to form the first mounting hole 416. The opening of the first mounting hole 416 faces the first mounting plate 34, and the first mounting hole 416 is exposed outside the door shell 12 through the relief opening 127. One end of the elastic member 60 abuts against the bottom wall of the first mounting hole 416, and the other end extends out of the door shell 12 through the relief opening 127 and abuts against the first mounting plate 34.

[0045] When the refrigerator 200 is in its normal state, the guide rail portion 32 of the guide rail bracket 30 is approximately horizontal (i.e., approximately parallel to the horizontal platform on which the refrigerator 200 is placed), the elastic element 60 is in an elastically compressed state, and the weight of the door 10 and the supporting force provided by the elastic element 60 form a torque balance around the rotation fulcrum O. At this time, the door 10 is in a vertical state (i.e., approximately perpendicular to the horizontal platform on which the refrigerator 200 is placed). If the gap between the door 10 and the cabinet 201 shows a trend of being larger at the top and smaller at the bottom, that is, the gap between the top of the door 10 and the mounting surface 2012 is greater than the gap between the bottom of the door 10 and the mounting surface 2012, the door 10 has a tendency to tilt relative to the horizontal platform, which increases the pressure on the elastic element 60. Therefore, the elastic element 60 will provide a greater supporting force to push the lower part of the door 10 (the part of the door 10 located below the rotation fulcrum O) away from the first mounting plate 34. Meanwhile, during the closing process of the drawer cabinet 100, that is, during the process of entering the storage space 2016, the guide rail bracket 30 provides a pulling force to the upper part of the door 10 into the storage space 2016 through the limiting part 43. This pulling force, together with the supporting force of the elastic element 60, causes the door 10 to be aligned around the rotation fulcrum O and fit against the mounting surface 2012, thereby realizing the adaptive adjustment of the posture of the door 10 and ensuring the uniformity of the gap between the door 10 and the cabinet 201.

[0046] To prevent excessive rotation during adaptive adjustment of the door 10, which could affect its installation stability, the drawer cabinet 100 in this embodiment also includes a limiting member 70. The limiting member 70 passes through the first mounting plate 34 and connects to the second mounting plate 414, located on the side of the elastic member 60 away from the limiting portion 43. This specification does not limit the specific structure of the limiting member 70; for example, the limiting member 70 can be a hinge structure connecting the first mounting plate 34 and the second mounting plate 414, or it can be an elastic rope or similar structure. In this embodiment, the limiting member 70 includes a screw 72 and a washer 74. The screw 72 passes through the first mounting plate 34 and is threaded to the second mounting plate 414. The washer 74 is connected to the screw 72 circumferentially and protrudes relative to the peripheral wall of the screw 72, located on the side of the first mounting plate 34 away from the second mounting plate 414. The gasket 74 is spaced apart from the first mounting plate 34 to allow for the rotation of the door 10.

[0047] To improve the stability of the screw 72 connection, a mounting post 417 is formed on the second mounting plate 414. The mounting post 417 extends along the thickness direction of the door body 10. One end of the post passes through the door shell 12 via the relief opening 127 and slidably passes through the first mounting plate 34. The other end is located inside the door body 10 and protrudes from the side of the second mounting plate 414 opposite to the inner liner 123. The mounting post 417 has a second mounting hole 418, the opening of which faces the first mounting plate 34. The second mounting hole 418 has an internal thread, into which the screw 72 is inserted and threadedly connected. A washer 74 abuts against the end of the mounting post 417 and protrudes from the peripheral wall of the mounting post 417 to prevent the screw 72 and the mounting post 417 from coming out of the first mounting plate 34. Screw 72 and washer 74 restrict large relative rotation between door 10 and guide rail bracket 30, preventing door 10 from falling off, while ensuring that door 10 can adaptively rotate relative to guide rail bracket 30 within a small range.

[0048] In this embodiment, there are two guide rail brackets 30, and two connectors 40, two elastic members 60, and two limiting members 70. Each connector 40, each elastic member 60, and each limiting member 70 corresponds to one guide rail bracket 30, which improves the stability of the adaptive adjustment of the door body 10.

[0049] In the embodiments provided above, the example is taken where the elastic element 60 is located below the rotation fulcrum O along the direction of gravity. In other embodiments, such as... Figure 9 As shown, the elastic element 60 and the pivot point O can also be arranged alternately along the direction of gravity G, that is, the elastic element 60 is above the pivot point O along the direction of gravity. It should be understood that the phrase "alternatingly arranged along the direction of gravity" or "the elastic element 60 is above the pivot point O along the direction of gravity" can be exemplified by: the elastic element 60 and the pivot point O being linearly arranged along the direction of gravity (e.g.,...). Figure 9 As shown), for example, when projected along the direction of gravity, the projections of the two have overlapping portions, so that... Figure 9 The orientation in the text is for descriptive reference. The elastic element 60 can be located directly above the rotation fulcrum O; alternatively, the elastic element 60 and the rotation fulcrum O do not need to be linearly arranged along the direction of gravity, but rather offset along the direction of gravity, and they are not set on the same horizontal plane. When projected along the direction of gravity, their projections have overlapping portions or there is a certain interval between their projections. From a macroscopic perspective, with... Figure 9 The orientation in the text is for descriptive reference. The elastic element 60 can be located to the upper left or upper right of the rotation fulcrum O.

[0050] In this embodiment, the elastic element 60 is in an elastically stretched state. One end of the elastic element 60 is fixedly connected to the first mounting plate 34, and the other end is fixedly connected to the bottom wall of the first mounting hole 416. The elastic element 60 provides tension to the door body 10 and the first mounting plate 34. This specification does not limit the specific structure of the elastic element 60. The elastic element 60 can be a tension spring, coil spring, or spring sheet, etc., in an elastically stretched state. In this embodiment, the elastic element 60 is a tension spring.

[0051] exist Figure 9 In the example shown, if door 10 and box 201 (e.g.) Figure 1 As shown, the gap between the door body 10 and the housing 201 exhibits a difference in size, with the upper part larger than the lower part. The elastic element 60, located at the top of the door body 10, increases the pulling force on the elastic element 60. Therefore, the elastic element 60 provides a greater reverse pulling force to pull the upper part of the door body 10 closer to the first mounting plate 34. This causes the door body 10 to align around the rotation fulcrum O and conform to the mounting surface 2012, achieving adaptive adjustment of the door body 10's posture and ensuring the uniformity of the gap between the door body 10 and the housing 201.

[0052] In the refrigerator 200 provided in this application, when there is a gap difference between the upper and lower parts of the door 10 and the cabinet 201, i.e., when the door 10 is tilted relative to the horizontal platform, the pressure on the elastic member 60 increases. Therefore, the elastic member 60 provides a greater supporting force to push the lower part of the door 10 away from the first mounting plate 34. At the same time, during the closing process of the drawer cabinet 100, i.e., during the process of entering the storage space 2016, the guide rail bracket 30 provides a pulling force to the upper part of the door 10 into the storage space 2016 through the limiting part 43. This pulling force, together with the supporting force of the elastic member 60, causes the door 10 to be aligned around the rotation fulcrum O and fit against the mounting surface 2012, thereby realizing the adaptive adjustment of the posture of the door 10 and ensuring the uniformity of the gap between the door 10 and the cabinet 201.
