Description

Technical Field

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

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature, keeping food or other items at a constant low temperature.

[0003] In related technologies, a refrigerator includes a cabinet, a door, a door shelf, a guide rail, and an adjustment component. The adjustment component is connected to the door shelf and the guide rail. The adjustment component is connected to different positions on the guide rail, thereby adjusting the position of the door shelf.

[0004] However, if the adjustment components fail, the door shelf can easily detach from the door. Summary of the Invention

[0005] This application provides a refrigerator in which the door shelf assembly is not easily detached from the door after the adjustment component fails.

[0006] This application provides a refrigerator, including:

[0007] The container is equipped with a storage compartment.

[0008] The door is rotatably connected to the cabinet to open or close the storage compartment;

[0009] Two guide rail assemblies are spaced apart along the width of the door body. The guide rail assemblies are connected to the door body, and the extension direction of the guide rail assemblies is consistent with the height direction of the door body. The guide rail assemblies are provided with multiple first positioning structures, which are arranged along the height direction. The guide rail assemblies also have second positioning structures.

[0010] Door shelf assembly, the door shelf assembly is provided with a third positioning structure;

[0011] An adjusting component is movably connected to the door shelf assembly. The adjusting component is movable relative to the door shelf assembly to connect or disconnect from the first positioning structure. The adjusting component is connected to different first positioning structures to adjust the position of the door shelf assembly along the height direction.

[0012] In the first state, the adjusting component is connected to the first positioning structure to support the door shelf assembly;

[0013] In the second state, the bottom of the third positioning structure abuts against the top of the second positioning structure to support the door shelf assembly.

[0014] The refrigerator provided in this application includes a cabinet, a door, two guide rail assemblies, a door shelf assembly, and an adjustment assembly. The guide rail assembly has multiple first positioning structures arranged along the height direction, and a second positioning structure. The door shelf assembly has a third positioning structure. In a first state, the adjustment assembly is connected to the first positioning structure to support the door shelf assembly. In a second state, the bottom of the third positioning structure abuts against the top of the second positioning structure to support the door shelf assembly. The first state represents the normal operating state of the adjustment assembly. The second state represents the inoperable state of the adjustment assembly. To allow the door shelf assembly to continue operating, the third and second positioning structures can be used to support the door shelf assembly, making it usable.

[0015] In some embodiments, when the bottom of the third positioning structure abuts against the top of the second positioning structure in the second state, the first positioning structure at the bottom is configured as an avoidance adjustment component.

[0016] In this way, when the adjustment component fails, there is no need to install a clearance mechanism to avoid it.

[0017] In some embodiments, in the second state, when the bottom of the third positioning structure abuts against the top of the second positioning structure, the adjusting component is located below the bottom first positioning structure, and the guide rail assembly is provided with a first avoidance portion to avoid the adjusting component.

[0018] This way, the height adjustment of the door shelf assembly in the first state is not easily affected.

[0019] In some embodiments, a plurality of first positioning structures are provided on one side of the guide rail assembly along the thickness direction of the door body, and a second positioning structure is provided on the other side of the guide rail assembly along the thickness direction.

[0020] The door shelf assembly and the adjustment assembly are arranged around the guide rail assembly on both sides along the thickness direction and on one side along the width direction;

[0021] The adjusting component moves relative to the door shelf assembly along the thickness direction to connect or disconnect from the first positioning structure.

[0022] In this way, the two guide rail assemblies can work together to restrict the position of the door shelf assembly along the width direction, and each guide rail assembly can restrict the position of the guide rail along the thickness direction.

[0023] In some embodiments, the regulating component includes:

[0024] A pull member is located at the bottom of the door shelf assembly. The pull member is slidably connected to the door shelf assembly and slides relative to the door shelf assembly along the thickness direction of the door body.

[0025] Two limiting members are provided on opposite sides of the pull member along the width direction. The limiting members are connected to the pull member in a driving connection and are slidably connected to the door shelf assembly. The limiting members slide relative to the door shelf assembly along the thickness direction to connect with or disconnect from the first positioning structure.

[0026] Two elastic elements are provided, and two elastic elements are set one-to-one with two limiting elements; each elastic element is connected to the door shelf assembly and the limiting element respectively, so that the elastic element is compressed when the limiting element slides away from the first positioning structure.

[0027] In this way, the structure of the adjustment components is relatively simple, and the installation efficiency is relatively high.

[0028] In some embodiments, the end face of the limiting member facing the first positioning structure is a first arc surface;

[0029] The first positioning structure includes:

[0030] The bottom of the limiting member abuts against the first support part to support the door shelf assembly;

[0031] The first contact portion is disposed on the top of the first support portion. The end face of the first contact portion facing the limiting member is a second arc surface, so that when the limiting member slides relative to the first positioning structure in the height direction, the first arc surface and the second arc surface make line contact.

[0032] In this way, the friction between the limiting component and the first contact part is small, making it easier for the user to operate.

[0033] In some embodiments, along a cross section perpendicular to the width direction, the center of the first arc formed by the first arc surface is located on the side away from the second arc surface, and the center of the second arc formed by the second arc surface is located on the side away from the first arc surface.

[0034] In this way, the user only needs to move the door shelf assembly upwards, without having to pull the pull piece.

[0035] In some embodiments, the pull member includes:

[0036] Handle structure;

[0037] Two blocking structures are respectively set on both sides of the handle structure along the width direction. The dimension of the blocking structure along the thickness direction is larger than that of the handle structure, and the bottom surface of the blocking structure is a slope.

[0038] In this way, the dimension of the blocking structure along the thickness direction is larger than that of the handle structure, and the bottom surface of the blocking structure is inclined, which can effectively prevent the user from operating the blocking structure. When the user pulls the pull component through the handle structure, the force on both sides of the pull component is more even, thereby causing the limiting components on both sides to move synchronously.

[0039] In some embodiments, the guide rail assembly is provided with a fourth positioning structure, which is disposed on top of the first positioning structure, and the fourth positioning structure includes:

[0040] The bottom of the limiting member abuts against the second support part to support the door shelf assembly;

[0041] The second contact portion is disposed on the top of the second support portion, and the end face of the second support portion facing the limiting member is flat.

[0042] A limiting part is provided at the top of the second contact part, and the limiting part is configured to restrict the limiting member from moving upward in the height direction.

[0043] This effectively prevents the door shelf assembly and adjustment assembly from detaching from the top of the guide rail assembly.

[0044] In some embodiments, the door shelf assembly includes:

[0045] The shelf body is transparent and has a receiving cavity.

[0046] The base plate is located at the bottom of the shelf body. The base plate is a non-transparent part. The bottom of the base plate has a cavity and two mounting cavities communicating with the cavity. The two mounting cavities are located on opposite sides of the cavity along the width direction.

[0047] The pulling member is slidably connected to the base plate and is located in the recessed cavity; the limiting member is slidably connected to the base plate and is located in the two mounting cavities respectively; the elastic member is connected to the base plate and is located in the two mounting cavities respectively.

[0048] Two sealing plates are connected to the base plate to cover the two mounting cavities. The sealing plates are non-transparent.

[0049] By making the shelf body transparent, users can easily observe the food inside the compartments. Conversely, by making the base plate and sealing plate opaque, the adjustment components can be concealed, thus improving aesthetics.

[0050] In some embodiments, the door body includes an interconnected door shell and a door liner, the door shell and the door liner enclosing a foam cavity;

[0051] The guide rail assembly includes a fixed base and a guide rail. The fixed base is located inside the foaming cavity and is connected to the door liner. The guide rail portion is located in the foaming cavity and is connected to the fixed base, while the remaining portion of the guide rail is located outside the foaming cavity.

[0052] The wear resistance of the guide rail is higher than that of the door frame.

[0053] In this way, the door shelf assembly slides along the guide rail, which is less prone to damage and helps to extend its service life. Attached Figure Description

[0089] In related technologies, a refrigerator includes a cabinet, a door, a door shelf, a guide rail, and an adjustment component. The adjustment component is connected to both the door shelf and the guide rail. The adjustment component is connected to different positions on the guide rail, thereby allowing the position of the door shelf to be adjusted. However, if the adjustment component fails, the door shelf is prone to detaching from the door.

[0090] This application provides a refrigerator, including a cabinet, a door, two guide rail assemblies, a door shelf assembly, and an adjustment assembly. The guide rail assembly has multiple first positioning structures arranged along the height direction, and a second positioning structure. The door shelf assembly has a third positioning structure. In a first state, the adjustment assembly is connected to the first positioning structure to support the door shelf assembly. In a second state, the bottom of the third positioning structure abuts against the top of the second positioning structure to support the door shelf assembly. The first state represents the normal operating state of the adjustment assembly. The second state represents the inoperable state of the adjustment assembly. To allow the door shelf assembly to continue operating, the third and second positioning structures can be used to support the door shelf assembly, making the door shelf assembly usable.

[0091] In some embodiments, the refrigeration equipment includes a housing. The housing includes an outer shell, a liner, and a compressor compartment.

[0092] The outer shell has a first receiving cavity with a first and a second opening, which are respectively located on opposite sides of the outer shell in the depth direction of the shell. The first opening can be located on the front side of the outer shell, and the second opening can be located on the rear side of the outer shell. The outer shell forms the appearance of the refrigerator.

[0093] The compressor compartment is located inside the outer shell, and its opening is opposite to the second access port, allowing the compressor and condenser to be placed inside the compressor compartment via the second access port and the opening. The storage liner is located inside the outer shell and has at least one storage compartment. The storage liner has a third access port opposite to the first access port, allowing items to be placed inside the storage compartment via the third access port and the first access port.

[0094] A foam layer is filled between the inner liner, outer shell, and compressor compartment. This foam layer insulates the storage compartment, ensuring its cooling performance. The foam layer also helps to minimize heat exchange between the storage compartment and the outside of the refrigerator, thus maintaining optimal cooling efficiency. The foam layer can be formed through foaming, such as polyurethane foam.

[0095] The storage compartment can be at least one. When there is only one storage compartment, it can be any of a refrigerator compartment, a freezer compartment, or a variable temperature compartment. When there are two or more storage compartments, they can include at least one or more of the following: refrigerator compartment, freezer compartment, or variable temperature compartment. The internal temperature of the refrigerator compartment can be maintained between approximately 0°C and 5°C for storing items in a refrigerated mode. The internal temperature of the freezer compartment can be maintained between approximately -30°C and 0°C for storing items in a frozen mode.

[0096] In some possible implementations, at least one of the storage compartments may also be configured as a vacuum chamber or a variable temperature chamber, etc.

[0097] In some embodiments, the refrigeration equipment includes a door that can be opened and closed to cover the front of the cabinet, thereby covering and opening the storage compartment for retrieving and placing items inside. It should be noted that the number of doors can be one, two, or more.

[0098] Figure 1 This is a partial structural diagram of a refrigerator provided in an embodiment of this application. Figure 2 for Figure 1 Exploded view.

[0099] See Figure 1 and Figure 2 As shown, the door body includes a door core 100.

[0100] The door body may include a door shell, which may be connected to the outside of the door liner 100 to form the appearance of the door body. The door shell may be rotatably connected to the cabinet body to allow the door to open or close the cold storage compartment. The door shell may include a door frame and a panel connected to the door frame. The panel is located on the side of the door frame opposite to the door liner 100, and the door liner 100 is connected to the door frame.

[0101] The door may also include a door insulation component, which can be disposed within the foam cavity formed by the door liner 100 and the door shell. The door insulation component insulates the storage compartment, minimizing heat exchange between the storage compartment and the outside of the refrigeration equipment, thus ensuring the refrigeration effect of the equipment. The door insulation component can be a foam layer.

[0102] In some embodiments, the refrigeration equipment includes a refrigeration system. The refrigeration system provides cooling to the storage compartment. Exemplarily, the refrigeration system may be housed within the enclosure.

[0103] A refrigeration system may include a compressor, a condenser, a throttling device, and an evaporator. The compressor, condenser, throttling device, and evaporator are connected in series via piping, through which refrigerant flows. The compressor and condenser may be located in the compressor compartment, while the evaporator may be located in the storage compartment.

[0104] When the compressor is working, low-temperature, low-pressure refrigerant is drawn into the compressor and compressed into high-temperature, high-pressure superheated gas in the compressor cylinder before being discharged into the condenser. The high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, its temperature continuously decreasing until it is gradually cooled into room-temperature, high-pressure saturated vapor, and further cooled into a saturated liquid. The pressure of the refrigerant remains almost constant throughout the condensation process. The throttling device may include a pressure reducing pipe or an electronic expansion valve. This application describes the throttling device as including a pressure reducing pipe, as pressure reducing pipes are low in cost and less prone to malfunction. The condensed saturated liquid refrigerant is throttled and depressurized through the pressure reducing pipe, turning the refrigerant into room-temperature, low-pressure wet vapor. This room-temperature, low-pressure wet vapor then absorbs heat and vaporizes through the evaporator, lowering not only the temperature of the evaporator and its surroundings but also turning the refrigerant into a low-temperature, low-pressure gas. The evaporator cools the air inside the storage room, thus lowering the temperature of the air inside the storage room. The refrigerant that comes out of the evaporator returns to the compressor, repeating the above process so that the evaporator can continuously cool the air in the storage room, thereby maintaining the storage room at the set temperature.

[0105] Furthermore, the refrigeration system may also include a dryer filter, which is connected between the condenser and the throttling device via piping. The dryer filter can filter out moisture and impurities from the refrigerant.

[0106] In some embodiments, the refrigerator may be a frost-free refrigerator.

[0107] Exemplarily, the enclosure may also be configured to form an evaporator chamber located at the rear of the storage compartment, for mounting the evaporator of the refrigeration system. A defrost heater for defrosting the evaporator may also be installed in the evaporator chamber. The enclosure may also be configured to form an air duct to allow cold air from the evaporator chamber to flow into the storage compartment, thereby lowering the temperature of the storage compartment. A fan is located in the evaporator chamber to accelerate airflow.

[0108] Figure 3 for Figure 1 The main view, Figure 4 For along Figure 3 Sectional view along the AA direction. Figure 5 for Figure 4 A magnified view of a section at point B.

[0109] See Figures 3 to 5 As shown, in some embodiments, the refrigerator includes two guide rail assemblies 200. The two guide rail assemblies 200 are spaced apart along the width direction of the door body, where the width direction of the door body is the direction indicated by the X-axis. The guide rail assemblies 200 are connected to the door body, and the extension direction of the guide rail assemblies 200 is consistent with the height direction of the door body, where the height direction of the door body is the direction indicated by the Z-axis.

[0110] Figure 6 This is a schematic diagram of the structure of the refrigerator door liner and guide rail assembly provided in an embodiment of this application. Figure 7 for Figure 6 A magnified view of a section at point C.

[0111] See Figure 6 and Figure 7 As shown, the guide rail assembly 200 is provided with a plurality of first positioning structures 210, which are arranged along the height direction, and the guide rail assembly 200 has a second positioning structure 220.

[0112] Figure 8 This is a schematic diagram of the structure of the refrigerator door shelf assembly and adjustment assembly provided in the embodiments of this application. Figure 9 for Figure 8 A magnified view of a section at point D.

[0113] See Figure 8 and Figure 9 As shown, in some embodiments, the refrigerator includes a door shelf assembly 300. The door shelf assembly 300 is provided with a third positioning structure 310.

[0114] In some embodiments, the refrigerator includes an adjustment assembly 400. The adjustment assembly 400 is movably connected to the door shelf assembly 300 and is movable relative to the door shelf assembly 300 to connect or disconnect from a first positioning structure 210. The adjustment assembly 400 is connected to different first positioning structures 210 to adjust the position of the door shelf assembly 300 in the height direction.

[0115] In the first state, the adjusting component 400 is connected to the first positioning structure 210 to support the door shelf assembly 300. In the second state, the bottom of the third positioning structure 310 abuts against the top of the second positioning structure 220 to support the door shelf assembly 300.

[0116] It should be noted that the first state can be the normal working state of the adjustment component 400. The second state can be the failure state of the adjustment component 400. In order for the door shelf assembly 300 to continue to work, the third positioning structure 310 and the second positioning structure 220 can be used to support the door shelf assembly 300, so that the door shelf assembly 300 can be used.

[0117] See Figure 6 As shown, in some embodiments, in the first state, the bottom of the third positioning structure 310 abuts against the top of the second positioning structure 220, and the adjusting component 400 is connected to the bottom first positioning structure 210. Thus, when the adjusting component 400 is functioning correctly, the door shelf assembly 300 is simultaneously supported by the cooperation of the adjusting component 400, the first positioning structure 210, the second positioning structure 220, and the third positioning structure 310, which helps improve the stability of the door shelf. The bottom first positioning structure 210 can be the very bottom first positioning structure 210.

[0118] It should be noted that when one of the limiting members 420 in the adjusting assembly 400 fails, for example, by breaking, and the other limiting member 420 is functioning normally, the normally functioning limiting member 420 can connect with the first positioning structure 210, thus eliminating the need for a clearance portion to avoid it. In the second state, the bottom of the third positioning structure 310 abuts against the top of the second positioning structure 220, and the bottom first positioning structure 210 is configured to avoid the adjusting assembly 400.

[0119] In some embodiments, in the second state, when the bottom of the third positioning structure 310 abuts against the top of the second positioning structure 220, the adjusting component 400 is located below the bottom first positioning structure 210. The guide rail assembly 200 is provided with a first clearance portion to avoid the adjusting component 400. In this way, the second positioning structure 220 and the third positioning structure 310 are less likely to affect the height adjustment of the door shelf assembly 300 in the first state. It should be noted that the bottom first positioning structure 210 can be the very bottom first positioning structure 210.

[0120] See Figure 5 , Figure 7 and Figure 9 As shown, in some embodiments, the guide rail assembly 200 has multiple first positioning structures 210 on one side along the thickness direction of the door body, and a second positioning structure 220 on the other side along the thickness direction. This makes it difficult to detect either the second positioning structure 220 or the first positioning structure 210, thus improving aesthetics. The thickness direction is the direction indicated by the Y-axis. Specifically, the second positioning structure 220 is located on the side facing the panel.

[0121] The door shelf assembly 300 and the adjusting assembly 400 are arranged around the guide rail assembly 200 on both sides along the thickness direction and one side along the width direction. In this way, the two guide rail assemblies 200 cooperate to limit the position of the door shelf assembly 300 along the width direction, and the guide rail assembly 200 can limit the position of the guide rail along the thickness direction. The width direction is the direction shown by the X-axis. The thickness direction is the direction shown by the Y-axis.

[0122] The adjusting component 400 moves relative to the door shelf assembly 300 along the thickness direction to connect or disconnect from the first positioning structure 210.

[0123] Figure 10 This is a cross-sectional view of the guide rail assembly in the refrigerator provided in an embodiment of this application. Figure 11 for Figure 10 A magnified view of a section at point F.

[0124] See Figure 10 and Figure 11 As shown, in some embodiments, the guide rail assembly 200 includes a mounting base 230 and a guide rail 240.

[0125] The fixing seat 230 is located inside the foaming cavity. The fixing seat 230 is pre-embedded in the foaming cavity. The fixing seat 230 can be fixedly connected to the door shell 100, or the fixing seat 230 can be fixedly connected to the door frame.

[0126] The guide rail 240 is partially located within the foaming cavity and connected to the fixing seat 230, while the remaining portion of the guide rail 240 is located outside the foaming cavity. The wear resistance of the guide rail 240 is higher than that of the door frame 100. This allows the door shelf assembly 300 to slide along the guide rail 240, making the guide rail 240 less prone to damage and extending its service life.

[0127] For example, the door liner 100 can be made of ABS (Acrylonitrile Butadiene Styrene). The guide rail 240 can be made of POM (polyformaldehyde).

[0128] Figure 12 This is a schematic diagram of the structure of the refrigerator door liner provided in an embodiment of this application. Figure 13 for Figure 12 A magnified view of a section at point E in the middle.

[0129] See Figure 12 and Figure 13 As shown, the door frame 100 is provided with a first convex positioning structure 110, which protrudes towards the guide rail 240. The first convex positioning structure 110 can be formed by vacuum forming.

[0130] Figure 14 This is a schematic diagram of the structure of the fixing base in the refrigerator provided in an embodiment of this application. Figure 15 for Figure 14 A cross-sectional view along the GG direction.

[0131] See Figure 14 and Figure 15As shown, the fixed base 230 is provided with a second convex hull positioning structure 231 that matches the first convex hull positioning structure 110. The second convex hull positioning structure 231 is engaged on the side of the first convex hull positioning structure 110 away from the guide rail 240, thereby realizing the positioning of the fixed base 230.

[0132] The door frame 100 has two first convex positioning structures 110 on one side, which are spaced apart along the height direction. The fixing base 230 has two second convex positioning structures 231, which correspond one-to-one with the first convex positioning structures 110.

[0133] Figure 16 This is a schematic diagram of the structure of the guide rail in the refrigerator provided in an embodiment of this application. Figure 17 This is a structural schematic diagram of the guide rail in a refrigerator provided in an embodiment of this application from another angle.

[0134] See Figure 16 and Figure 17 As shown, in some embodiments, the guide rail 240 is provided with a second clearance portion 241 that avoids the first convex hull positioning structure 110. The second clearance portion 241 is larger in the height direction than the first convex hull positioning structure 110, so that after the bottom of the second clearance portion 241 contacts the bottom of the first convex hull positioning structure 110, the guide rail 240 can move downward in the height direction until the top of the second clearance portion 241 abuts against the top of the first convex hull positioning structure 110.

[0135] See Figure 13 , Figure 15 and Figure 17 As shown, in some embodiments, the fixed base 230 is provided with an elastic buckle 232, the guide rail 240 is provided with a first limiting plate 242, and the door liner 100 is provided with a third clearance part 120 that avoids the first limiting plate 242. The first limiting plate 242 is inserted into the foaming cavity through the third clearance part 120.

[0136] The elastic buckle 232 includes a first flat portion 2321 and a first inclined portion 2322. The first flat portion 2321 is connected to the fixing base 230, and the first inclined portion 2322 is located at the bottom of the first flat portion 2321. From top to bottom, the first inclined portion 2322 is inclined towards the guide rail 240. That is, from top to bottom, the distance between the first inclined portion 2322 and the guide rail 240 decreases.

[0137] When installing the guide rail 240, the first limiting plate 242 is positioned inside the foaming cavity via the third clearance part 120, above the elastic buckle 232. Then, the guide rail 240 moves downwards along the height direction, causing the first limiting plate 242 to press down on the elastic buckle 232, deforming it. When the first limiting plate 242 is below the elastic buckle 232, the elastic buckle 232 returns to its original shape. In this way, the elastic buckle 232 can restrict the upward movement of the guide rail 240.

[0138] In some embodiments, a first reinforcing rib 243 is provided on the top of the first limiting plate 242 to reduce the deformation of the first limiting plate 242.

[0139] See Figure 13 , Figure 15 and Figure 17 As shown, in some embodiments, the fixed base 230 is provided with a support structure 233. The guide rail 240 is provided with a second limiting plate 244. The door liner 100 is provided with a fourth clearance part 130 to avoid the second limiting plate 244, and the second limiting plate 244 is inserted into the foaming cavity through the fourth clearance part 130.

[0140] When installing the guide rail 240, the second limiting plate 244 is inserted into the foam cavity via the fourth clearance part 130, with the second limiting plate 244 positioned above the support structure 233. Then, the guide rail 240 moves downward along the height direction until the bottom of the second limiting plate 244 contacts the top of the support structure 233. In this way, the elastic buckle 232 can restrict the downward movement of the guide rail 240.

[0141] In some embodiments, a second reinforcing rib 245 is provided on the top of the second limiting plate 244 to reduce the deformation of the second limiting plate 244.

[0142] In some embodiments, the number of second limiting plates 244 is at least two, and the at least two second limiting plates 244 are spaced apart along the height direction, and the number of support structures 233 is at least two. Exemplarily, the number of second limiting plates 244 is three, and the number of support structures 233 is three.

[0143] See Figure 13 , Figure 15 and Figure 17As shown, in some embodiments, a latch 234 is provided on the top of the support structure 233. The latch 234 includes a second flat portion 2341 and a second inclined portion 2342. The second flat portion 2341 is connected to the support structure 233, and the second inclined portion 2342 is disposed on top of the second flat portion 2341. From top to bottom, the dimension of the second inclined portion 2342 increases along the width direction, and the end face of the second inclined portion 2342 facing away from the fixing base 230 along the width direction is flush with the second flat portion 2341. The second limiting plate 244 is provided with a notch that matches the latch 234.

[0144] When installing the guide rail 240, the second limiting plate 244 is inserted into the foam cavity via the fourth clearance part 130. The second limiting plate 244 is located above the support structure 233. Then, the guide rail 240 is moved downward along the height direction, and the buckle 234 is located in the notch. Under the action of the second inclined part 2342 of the buckle 234, the second limiting plate 244 approaches the fixing seat 230 along the width direction, and the bottom of the second limiting plate 244 contacts the top of the support structure 233. In this way, the buckle 234 can restrict the position of the guide rail 240 along the width direction.

[0145] One of the support structures 233 is provided with at least one buckle 234.

[0146] Figure 18 This is a schematic diagram of the refrigerator door shelf assembly and adjustment assembly from another angle, provided in an embodiment of this application. Figure 19 for Figure 18 A schematic diagram of the structure after removing the sealing plate. Figure 20 for Figure 19 A magnified view of a section at point H.

[0147] See Figures 18 to 20 As shown, in some embodiments, the adjustment assembly 400 includes a pull member 410. The pull member 410 is for a user to pull.

[0148] The pull member 410 is located at the bottom of the door shelf assembly 300. The pull member 410 is slidably connected to the door shelf assembly 300 and slides relative to the door shelf assembly 300 along the thickness direction of the door body.

[0149] In some embodiments, the adjustment assembly 400 includes two limiting members 420. The limiting members 420 are used to connect with the first positioning structure 210.

[0150] Two limiting members 420 are disposed on opposite sides of the pulling member 410 along the width direction. The limiting members 420 are kinetically connected to the pulling member 410 and slidably connected to the door shelf assembly 300. The limiting members 420 slide relative to the door shelf assembly 300 along the thickness direction to connect or disconnect from the first positioning structure 210. The pulling member 410 and the limiting members 420 move synchronously. When the user pulls the pulling member 410, the pulling member 410 drives the limiting members 420 to move synchronously.

[0151] In some embodiments, the adjusting assembly 400 includes two elastic members 430. The elastic members 430 are sleeved on the limiting member 420, and their two ends are connected to the door shelf assembly 300 and the limiting member 420, respectively. When the limiting member 420 slides away from the first positioning structure 210, it compresses the elastic members 430. The elastic members 430 and the limiting members 420 are configured in a one-to-one correspondence. Thus, when the user stops applying external force to the pulling member 410, the limiting member 420 can extend outward along the thickness direction under the elastic force of the elastic members 430.

[0152] Specifically, the elastic element 430 can be a spring or elastic rubber.

[0153] Figure 21 This is a schematic diagram of the structure of the pull member in the refrigerator provided in an embodiment of this application. Figure 22 This is a schematic diagram of the structure of the limiting component in the refrigerator provided in an embodiment of this application.

[0154] See Figure 21 and Figure 22 As shown, in some embodiments, the pulling member 410 has fixing structures 411 on both sides along its width. The limiting member 420 has a fixing groove 422 that matches the fixing structure 411. The fixing structure 411 and the fixing groove 422 are interference-fitted, thereby ensuring that the pulling member 410 and the limiting member 420 slide synchronously. This results in high connection efficiency.

[0155] See Figure 5 As shown, in some embodiments, the end face of the limiting member 420 facing the first positioning structure 210 is a first arc surface 421.

[0156] The first positioning structure 210 includes a first support portion 211, and the bottom of the limiting member 420 abuts against the first support portion 211 to support the door shelf assembly 300.

[0157] The first positioning structure 210 includes a first contact portion 212, which is disposed on the top of the first support portion 211. The end face of the first contact portion 212 facing the limiting member 420 is a second arc surface 2121, so that when the limiting member 420 slides relative to the first positioning structure 210 in the height direction, the first arc surface 421 and the second arc surface 2121 are in line contact. In this way, the friction between the limiting member 420 and the first contact portion 212 is small, which facilitates user operation.

[0158] In some embodiments, along a cross section perpendicular to the width direction, the center of the first arc formed by the first arc surface 421 is located on a side away from the second arc surface 2121, and the center of the second arc formed by the second arc surface 2121 is located on a side away from the first arc surface 421. Thus, the user needs to move the door shelf assembly 300 upwards without pulling the pull member 410. Here, the width direction is the direction indicated by the X-axis.

[0159] It should be noted that the limiting member 420 is placed on the first support portion 211 of the first positioning structure 210, fixing the door shelf assembly 300 at a certain height. When the door shelf assembly 300 is adjusted upwards, it is pushed upwards. The cooperation between the first arc surface 421 of the limiting member 420 and the second arc surface 2121 of the first contact portion 212 causes the limiting member 420 to compress the spring, and the limiting member 420 enters the first support portion 211 of the upper layer, that is, the door shelf assembly 300 is adjusted upwards by one layer. When the door shelf assembly 300 is adjusted downwards, the pulling member 410 is pulled. The pulling member 410 causes the limiting member 420 to compress the elastic member 430 and retract, pushing the door shelf assembly 300 downwards. The limiting member 420 enters the first support portion 211 of the lower layer, that is, the door shelf assembly 300 is adjusted downwards by one layer.

[0160] See Figure 5 As shown, in some embodiments, the guide rail assembly 200 is provided with a fourth positioning structure 250, which is disposed on top of the first positioning structure 210. The fourth positioning structure 250 is used to effectively prevent the door shelf assembly 300 and the adjustment assembly 400 from falling off the top of the guide rail assembly 200.

[0161] In some embodiments, the fourth positioning structure 250 includes a second support portion 251, and the bottom of the limiting member 420 abuts against the second support portion 251 to support the door shelf assembly 300.

[0162] In some embodiments, the fourth positioning structure 250 includes a second contact portion 252, which is disposed on the top of the second support portion 251, and the end face of the second support portion 251 facing the limiting member 420 is a plane.

[0163] In some embodiments, the fourth positioning structure 250 includes a limiting portion 253 disposed on the top of the second contact portion 252, and the limiting portion 253 is configured to restrict the limiting member 420 from moving upward in the height direction.

[0164] See Figure 19 and Figure 21 As shown, in some embodiments, the pull member 410 includes a handle structure 412.

[0165] The pull member 410 includes two blocking structures 413, which are respectively disposed on both sides of the handle structure 412 along the width direction. The dimension of the blocking structure 413 along the thickness direction is larger than that of the handle structure 412, and the bottom surface of the blocking structure 413 is a slope.

[0166] Understandably, the thickness dimension of the blocking structure 413 is larger than that of the handle structure 412, and the bottom surface of the blocking structure 413 is inclined, which can effectively prevent the user from operating the blocking structure 413. When the user pulls the pull member 410 through the handle structure 412, the force on both sides of the pull member 410 is relatively uniform, thereby causing the limiting members 420 on both sides to move synchronously. In this way, it can effectively prevent the situation where one side of the limiting member 420 is unlocked while the other side is not, due to the user pulling both sides.

[0167] See Figure 8 , Figures 18 to 20 As shown, in some embodiments, the door shelf assembly 300 includes a shelf body 320, which is transparent and has a receiving cavity.

[0168] The door shelf assembly 300 includes a base plate 330, which is disposed at the bottom of the shelf body 320 and is a non-transparent component.

[0169] The bottom of the base plate 330 is provided with a cavity 331 and two mounting cavities 332 communicating with the cavity 331. The two mounting cavities 332 are located on opposite sides of the cavity 331 along the width direction.

[0170] The pull member 410 is slidably connected to the base plate 330, and the pull member 410 is disposed in the cavity 331. In this way, the pull member 410 is not easily observed from the outside, which helps to improve the aesthetics.

[0171] Two limiting members 420 are respectively disposed in two mounting cavities 332, and two elastic members 430 are connected to the base plate 330. The limiting members 420 are slidably connected to the base plate 330.

[0172] Two sealing plates 340 are connected to the base plate 330 to cover the two mounting cavities 332. The sealing plates 340 are non-transparent.

[0173] Understandably, by making the shelf body 320 transparent, it is convenient for users to observe the food inside the storage cavity. By making the bottom plate 330 and the sealing plate 340 opaque, and placing the limiting member 420 and the elastic member 430 within the mounting cavity 332, the bottom plate 330 and the sealing plate 340 can cover the limiting member 420 and the elastic member 430, thereby improving aesthetics.

[0174] For example, the transparent part can be made of glass or acrylic, while the non-transparent part can be made of ABS or POM, etc.

[0175] See Figure 20 As shown, a limiting structure 333 is provided on the base plate 330. There are two limiting structures 333, which are arranged opposite each other along the width direction. A blocking structure 413 is located between the two limiting structures 333. The limiting structure 333 contacts the blocking structure 413, thereby restricting the position of the pulling member 410 along the width direction.

[0176] In some embodiments, the pull member 410 is partially located at the bottom of the limiting structure 333, thereby limiting the position of the pull member 410 in the height direction.

[0177] See Figure 8 and Figure 9 As shown, in some embodiments, the door shelf assembly 300 is provided with surrounding portions 350 on both sides along the width direction for surrounding the guide rail assembly 200 on both sides along the thickness direction and one side along the width direction, and the surrounding portions 350 are recessed toward the interior of the door shelf assembly 300.

[0178] The inner wall of the surrounding part 350 along the width direction is provided with a contact rib 360, which extends along the height direction. The contact rib 360 is used to contact the guide rail 240, thereby reducing friction and facilitating the smooth sliding of the door shelf assembly 300.

[0179] Figure 23 for Figure 3 Sectional view along the MM direction. Figure 24 for Figure 23 A magnified view of a portion of point N in the middle.

[0180] In some embodiments, the distance between the contact rib 360 and the guide rail 240 along the width direction is smaller than the distance between the door shelf assembly 300 and the door frame 100. This helps to ensure that the door frame 100 and the door shelf assembly 300 do not contact each other, thereby facilitating smooth sliding of the door shelf assembly 300.

[0181] Specifically, along the width direction, the distance between the contact rib 360 and the guide rail 240 is the first distance a. Along the thickness direction, the distances along the width direction between the door shelf assembly 300 and the door core 100 located on both sides of the surrounding portion 350 are the second distance b and the third distance c, respectively. The first distance a is less than the second distance b, and the first distance a is less than the third distance c.
