Description

Technical Field

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

[0002] As an indispensable home appliance in modern families, refrigerators have become increasingly sophisticated and functional with the development of technology, in order to meet users' needs for food preservation, storage, and other aspects.

[0003] In the process of conceiving and implementing this application, the applicant discovered at least the following problems: Currently, refrigerator doors are generally made of foam. In order to ensure the sealing performance and appearance of the door, there must be no leakage during the foaming process. Usually, sponge is manually filled at the corners where the door shell, inner liner and end cap are connected for sealing. This is labor-intensive and the sealing effect is not ideal, which can easily cause leakage.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0005] The main objective of this application is to provide a refrigerator that prevents material leakage during foaming and improves the strength of the door.

[0006] To achieve the above objectives, this application provides a refrigerator, comprising:

[0007] The enclosure includes a refrigeration compartment;

[0008] The door, movably connected to the enclosure and configured to open and close the refrigeration compartment, has the following features:

[0009] The door shell is located on the side of the door body facing away from the box body;

[0010] The inner liner of the door is located on the side of the door facing the cabinet.

[0011] The lower end cover, located at the bottom of the door, has the following features:

[0012] The abutment, along the depth direction of the housing, abuts against the inner liner of the door and is fixed to the side of the inner liner facing the door shell.

[0013] The beneficial effects of this application are: by setting the abutment, the sealing of the connection between the inner door liner and the lower end cover is ensured, preventing material leakage, enhancing the foaming quality of the door body, and improving the overall thermal insulation performance of the door body; in addition, since the foaming material has a certain structural support after curing, the bonding strength between the inner door liner and the lower end cover can be enhanced by utilizing the bonding and support effects of the foaming material, thereby improving the strength of the door body.

[0014] Based on the above technical solution, the following improvements can be made to this application.

[0015] In some alternative embodiments, there are at least two abutments, located at opposite ends of the lower end cover along the width of the housing.

[0016] The above technical solution has the following advantages or beneficial effects: This design improves the sealing performance of the door shell, inner liner and lower end cover corners in the bottom width direction of the door body, ensuring the sealing integrity of the entire foam cavity in the bottom width direction and avoiding material leakage at the corners.

[0017] In some alternative implementations, the abutment is an abutment plate.

[0018] The above technical solution has the following advantages or beneficial effects: the plate structure can apply pressure to the inner liner of the door more evenly, ensuring that the entire contact surface is subjected to uniform force, and fundamentally avoiding the possibility of foam material leaking from the bottom.

[0019] In some alternative embodiments, the abutment includes a first abutment portion and a second abutment portion connected together, with an included angle between the extending directions of the first abutment portion and the extending directions of the second abutment portion.

[0020] The above technical solution has the following advantages or beneficial effects: the first abutment and the second abutment are structures with two different extension directions, which can improve the strength of the abutment itself. Under the pressure of the expansion of the foam material, or when the door is impacted, the abutment is not easy to bend, break or loosen from the lower cover, thus ensuring the support and sealing effect.

[0021] In some alternative embodiments, the first abutment portion is connected to the bottom end of the lower end cap;

[0022] The first abutment part is arc-shaped and is attached to the lower side wall of the inner liner of the door.

[0023] The above technical solution has the following advantages or beneficial effects: the arc-shaped first abutment part fits the arc shape of the lower side wall of the door liner, which can guide the door liner to the precise installation position during assembly, simplifying the assembly process and improving accuracy and efficiency.

[0024] In some alternative embodiments, the second abutment portion has multiple through holes that extend through the opposite sides of the abutment member.

[0025] The above technical solution has the following advantages or beneficial effects: it ensures that the areas behind the abutment and between the abutment and the inner liner of the door, which are most likely to trap air and form foam dead corners, can also be fully filled by the foaming material, thereby improving the filling effect of the foaming material, enhancing the foaming quality of the door, and improving the overall thermal insulation performance of the door.

[0026] In some alternative embodiments, the lower end cap further comprises:

[0027] The connecting part extends along the direction facing the door shell, and there is an angle between the extending direction of the connecting part and the extending direction of the abutment;

[0028] Along the width direction of the housing, at least one of the first abutting portion and the second abutting portion has a first gap with the connecting portion.

[0029] The above technical solution has the following advantages or beneficial effects: the foaming material, through the first gap, fully fills every gap between the abutment and the inner door liner. After curing, the foaming material firmly anchors the abutment and the inner door liner together, and its connection strength is far superior to simple physical abutment or screw connection, effectively resisting separation caused by various stresses.

[0030] In some alternative embodiments, the first abutment portion is horizontal;

[0031] Along the depth direction of the box, there is a second gap between the side wall of the first contact part and the lower side wall of the inner liner of the door.

[0032] The above technical solution has the following advantages or beneficial effects: Since the foaming material encounters resistance when expanding and flowing, this second gap reduces the flow resistance, ensuring that the foaming material can fill the corner between the abutment and the arc-shaped inner liner before expanding and curing, thereby improving the connection strength between the abutment and the inner liner and extending the service life of the door.

[0033] In some alternative embodiments, a third gap is provided between the first abutment and the bottom end of the lower cover along the height direction of the housing.

[0034] The above technical solution has the following advantages or beneficial effects: During foaming, the foaming material can be filled between the abutment and the inner liner through the third gap, the foaming material is fully filled, the filling effect of the foaming material is improved, the foaming quality of the door is enhanced, the bonding strength between the inner liner and the lower end cover is enhanced, and the overall thermal insulation performance of the door is improved.

[0035] In some alternative embodiments, the first abutment portion and the second abutment portion are integrally formed.

[0036] The above technical solution has the following advantages or beneficial effects: by making the first abutting part and the second abutting part integrally molded, not only can the connection strength between the first abutting part and the second abutting part be improved, but also a seamless connection between the first abutting part and the second abutting part can be achieved, thereby reducing the risk of cracking at the connection position of the first abutting part and the second abutting part.

[0037] The refrigerator provided in this application includes a cabinet having a cooling compartment; a door movably connected to the cabinet and configured to open and close the cooling compartment, the door having: a door shell located on the side of the door facing away from the cabinet; a door liner located on the side of the door facing the cabinet; and a lower end cover located at the bottom of the door, the lower end cover having: an abutment member along the depth direction of the cabinet, the abutment member abutting against the door liner and fixed to the side of the door liner facing the door shell.

[0038] The abutment component ensures the sealing of the connection between the inner door liner and the lower end cover, preventing material leakage, enhancing the foaming quality of the door body, and improving the overall thermal insulation performance of the door body. In addition, since the foamed material has a certain structural support function after curing, the bonding and support functions of the foamed material can be used to enhance the bonding strength between the inner door liner and the lower end cover, thereby improving the strength of the door body.

[0063] Currently, refrigerator doors are generally made by foam molding. To ensure the sealing performance and appearance of the door, there must be no leakage during the foaming process. Usually, sponge is manually filled at the corners where the door shell, inner liner and end cap are connected for sealing. This is labor-intensive and the sealing effect is not ideal, which can easily cause leakage.

[0064] To overcome the deficiencies in the prior art, the refrigerator provided in this application ensures the sealing of the connection between the inner door liner and the lower end cover by setting the abutment part, preventing material leakage, enhancing the foaming quality of the door body, and improving the overall heat insulation performance of the door body; in addition, since the foaming material has a certain structural support after curing, the bonding strength between the inner door liner and the lower end cover can be enhanced by utilizing the bonding and support effects of the foaming material, thereby improving the strength of the door body.

[0067] like Figures 1 to 6 As shown, this application embodiment provides a refrigerator 100, including:

[0068] The enclosure 110 has a refrigeration compartment;

[0069] Door 120, movably connected to housing 110, and configured to open and close the refrigeration compartment, has the following features:

[0070] Door shell 121 is located on the side of door body 120 facing away from box body 110;

[0071] The inner door liner 122 is located on the side of the door body 120 facing the box body 110;

[0072] The lower end cover 123 is located at the bottom end of the door body 120, and the lower end cover 123 has:

[0073] The abutment 124 abuts against the inner door liner 122 along the depth direction of the housing 110 and is fixed to the side of the inner door liner 122 facing the door shell 121.

[0074] With the above-mentioned configuration, namely, the refrigerator 100 of this application embodiment, through the setting of the abutment member 124, ensures the sealing of the connection between the door liner 122 and the lower end cover 123, prevents material leakage, enhances the foaming quality of the door body 120, and improves the overall heat preservation performance of the door body 120; in addition, since the foaming material has a certain structural support function after curing, the bonding and support function of the foaming material can be used to enhance the bonding strength between the door liner 122 and the lower end cover 123, thereby improving the strength of the door body 120.

[0075] It should be noted that the following provides a detailed explanation of each structure.

[0076] [Box 110]

[0077] The refrigerator 100 of this application embodiment may include a cabinet 110 and a door 120. The cabinet 110 may be configured with a refrigeration compartment. The refrigeration compartment has an opening for storing food and other items. There may be one or more refrigeration compartments. When there are multiple refrigeration compartments, the multiple refrigeration compartments may be divided into a refrigerator compartment, a freezer compartment, or a variable temperature compartment, etc.

[0078] For example, the refrigerator body 110 may include an outer shell and an inner liner, the outer shell defining the external boundary of the refrigerator 100. The inner liner may be disposed within and connected to the outer shell. The inner liner may be recessed inward to form a cooling compartment. An insulation layer may be filled between the outer shell and the inner liner, which can insulate the cooling compartment, thereby reducing the energy consumption of the refrigerator 100.

[0079] The box 110 adopts a hollow cuboid structure. It is understood that in other embodiments, the box 110 may also adopt a hollow shell structure of other shapes.

[0080] In some embodiments, a refrigeration assembly (not shown) is provided inside the cabinet 110 to provide refrigeration for the interior of the refrigerator 100 in order to maintain a low-temperature environment in each refrigeration compartment.

[0081] Refrigeration components include compressors, condensers, evaporators, and throttling devices. The specific structure and connections of these components can be found in relevant technical documentation on refrigeration components, and will not be elaborated upon here. The evaporator provides different amounts of cooling capacity to different types of storage spaces, resulting in varying temperatures within these spaces. For example, the temperature inside a refrigerator is generally between 2°C and 10°C, preferably between 4°C and 7°C. The temperature range inside a freezer is generally between -22°C and -14°C. Different types of items have different optimal storage temperatures, and consequently, different suitable storage spaces. For example, fruits and vegetables are suitable for storage in refrigerators or crisper compartments, while meat is suitable for storage in freezers.

[0082] It should be noted that, as Figure 1 As shown, X represents the width direction of the box 110, Y represents the depth direction of the box 110, and Z represents the height direction of the box 110.

[0083] [Gate 120]

[0084] It should be noted that the door 120 can be connected to the cabinet 110 to open or close the refrigeration compartment.

[0085] A door 120 is disposed on the front surface of the enclosure 110 to enclose the refrigeration compartment. The door 120 is configured to open and close the refrigeration compartment, meaning it can open and close the front opening of the enclosure 110. Doors 120 can be correspondingly assigned to refrigeration compartments; that is, each refrigeration compartment can have one or more doors 120. The number of refrigeration compartments and doors 120, as well as the function of the refrigeration compartments, can be selected based on specific circumstances. One door 120 can be assigned to the same refrigeration compartment. Alternatively, two doors 120 can be assigned to the same refrigeration compartment.

[0086] In some possible implementations of this application, the door 120 can be rotatably connected to the housing 110 about the height direction Z of the housing 110. The door 120 can be pulled or pushed to rotate relative to the housing 110, thereby opening or closing the refrigeration compartment.

[0087] In some embodiments, the door 120 is a rotating door structure. The door 120 is rotatably disposed on the front side of the box 110, and in this case, the door 120 can be used as a general door structure, such as a refrigerator door 126, a variable temperature door 127, etc.

[0088] Specifically, the door 120 and the cabinet 110 can be connected by a hinge so that the door 120 of the refrigerator 100 can rotate around the axis of the hinge, thereby opening and closing the door 120 and opening and closing the corresponding refrigeration compartment.

[0089] In some embodiments, the door 120 can also be a sliding door structure. The door 120 is slidably disposed on the front side of the cabinet 110, and in this case, the door 120 can be used as a drawer door. Specifically, guide rails (not shown in the figure) are respectively provided on the left and right inner side walls of the cabinet liner, and the door 120 is connected to the guide rails on both sides, thereby realizing the sliding function of the door 120 and realizing the opening and closing of the refrigeration compartment by extending and retracting the guide rails.

[0090] It should be noted that the door body 120 has an upper end cover 125 and a lower end cover 123. The lower end cover 123 is detachably installed at the bottom of the door body 120, and the upper end cover 125 is detachably installed at the top of the door body 120.

[0091] The detachable methods include bolt connection and snap-fit ​​connection.

[0092] In some embodiments, the door 120 includes a refrigerator door 126 and a variable temperature door 127. The refrigerator door 126 is movably connected to one side of the cabinet 110 in the height direction, and the variable temperature door 127 is located below the refrigerator door 126.

[0093] By placing the refrigerator door 126 and the variable temperature door 127 at different heights in the refrigerator 100, users can rationally arrange the storage space according to their usage frequency and needs. The refrigerator door 126 is usually used to store food that is frequently accessed daily, while the variable temperature door 127 is used for long-term storage, and its lower position is also more suitable for storing heavier frozen items.

[0094] It should be noted that the door 120 may include a refrigerator door 126 and a variable temperature door 127. The refrigerator door 126 and the variable temperature door 127 are arranged sequentially along the height of the cabinet 110. Generally, the refrigerator door 126 is located above the variable temperature door 127. The refrigerator door 126 is used to open or close the refrigerator compartment, and the variable temperature door 127 is used to open or close the freezer compartment.

[0095] Figure 7 An exploded schematic diagram of the second type of variable temperature door in a refrigerator provided in an embodiment of this application.

[0096] like Figure 7 As shown, in some embodiments, the door shell 121 includes a door panel 1211, a left side panel 1212, and a right side panel 1213. The left side panel 1212, the right side panel 1213, the upper end cover 125, and the lower end cover 123 are located around the door panel 1211. Therefore, after the door panel 1211, the upper end cover 125, the lower end cover 123, the left side panel 1212, the right side panel 1213, and the inner door liner 122 are assembled, a closed space can be formed. A foaming agent can be injected into this closed space. Under certain temperature conditions, the foaming agent expands and solidifies to fill the entire closed space. Then, the door panel 1211, the upper end cover 125, the lower end cover 123, the left side panel 1212, the right side panel 1213, and the inner door liner 122 can be fixed together as a whole by the insulation layer formed by the foaming agent. At the same time, the insulation layer located in this closed space can also prevent heat exchange between the storage compartment inside the refrigerator 100 and the outside, thereby achieving the insulation effect.

[0097] For example, the door panel 1211 is a covering that constitutes the main appearance, such as being made of sheet metal and stamped by a mold.

[0098] It should be noted that, during the production of the lower end cover 123 and the inner door liner 122, tolerance issues were taken into consideration. Even when the lower end cover 123 and the inner door liner 122 are assembled, the assembly may still be unstable. On the one hand, this can lead to material leakage during foaming. Material leakage can result in insufficient filling of the foam material inside the door body 120, forming cavities or air bubbles, which seriously damages the integrity of the insulation layer. On the other hand, the two are prone to detachment, resulting in poor overall structural stability of the door body 120.

[0099] Therefore, the lower end cover 123 is provided with an abutment 124, which abuts against the inner door liner 122, thereby increasing the connection strength between the inner door liner 122 and the lower end cover 123.

[0100] Specifically, by providing an abutment 124 on the lower end cover 123 and having it abut against the side of the inner door liner 122 facing the door shell 121 along the depth direction of the housing 110, the support and connection strength of the bottom structure of the door body 120 are effectively strengthened, preventing the door body 120 from deforming or loosening due to long-term opening and closing or bearing weight (such as placing items).

[0101] Furthermore, the supporting effect of the abutment 124 on the inner door liner 122 helps maintain the relative positional stability between the inner door liner 122 and the cabinet 110, thereby ensuring that the sealing strip between the door liner 120 and the cabinet 110 is evenly pressed when the door liner 120 is closed, reducing cold air leakage, improving refrigeration efficiency and reducing energy consumption.

[0102] In addition, the lower end cover 123 and the inner door liner 122 are directly positioned and fixed by the abutment member 124, which may reduce the use of additional connecting parts, reduce assembly complexity, improve production efficiency, and reduce dimensional deviations caused by assembly errors.

[0103] In some alternative embodiments, there are at least two abutments 124, located at opposite ends of the lower end cover 123 along the width direction of the housing 110.

[0104] The above technical solution has the following advantages or beneficial effects: This setting improves the sealing performance of the bottom width direction of the door body 120, namely the corners of the door shell 121, the inner door liner 122 and the lower end cover 123, ensuring the sealing integrity of the entire foam cavity in the bottom width direction and avoiding material leakage at the corners.

[0105] In some alternative implementations, the abutment 124 is an abutment plate.

[0106] The above technical solution has the following advantages or beneficial effects: the plate structure can apply pressure to the inner liner 122 more evenly, ensuring that the entire contact surface is subjected to uniform force, and fundamentally avoiding the possibility of foam material leaking from the bottom.

[0107] Furthermore, the large-area abutment plate significantly increases the contact area with the inner door liner 122, effectively adding a support plate to the bottom of the door body 120. This makes the bottom of the door body 120 more rigid, more effectively resisting torsion and bending deformation, and maintaining the long-term stability of the door body 120 structure.

[0108] In some alternative embodiments, the abutment 124 includes a first abutment portion 1241 and abutment portion 1242 connected together, with an included angle between the extending direction of the first abutment portion 1241 and the extending direction of the second abutment portion 1242.

[0109] The above technical solution has the following advantages or beneficial effects: the first abutting part 1241 and the second abutting part 1242 are structures with two different extension directions, which can improve the strength of the abutting part 124 itself. Under the pressure of the expansion of the foam material, or when the door body 120 is impacted, the abutting part 124 is not easy to bend, break or loosen from the lower end cover 123, thus ensuring the support and sealing effect.

[0110] In some embodiments, the first abutting portion 1241 extends along the depth direction Y of the housing 110, and the second abutting portion 1242 extends along the height direction Z of the housing 110.

[0111] In some alternative embodiments, the first abutment portion 1241 is connected to the bottom end of the lower end cover 123;

[0112] The first abutting part 1241 is arc-shaped and is attached to the lower side wall of the inner door liner 122.

[0113] The above technical solution has the following advantages or beneficial effects: the arc-shaped first abutment part 1241 fits the arc shape of the lower side wall of the door inner liner 122, which can guide the door inner liner 122 to the precise installation position during assembly, simplifying the assembly process and improving accuracy and efficiency.

[0114] It should be noted that, since the lower side wall of the inner door liner 122 has an arc-shaped structure, when the first abutting part 1241 is an arc-shaped part and the two structures match each other, the first abutting part 1241 can be better attached to the inner door liner 122, thereby improving the connection stability between the two.

[0115] The curved fit design forces the inner door liner 122 to press more tightly against the curved first contact part 1241 when the foam material expands and generates upward pressure, resulting in a better sealing effect and thus solving the problem of material leakage.

[0116] Furthermore, the first contact part 1241, by fitting closely to the lower side wall of the inner door liner 122 over a large area, can seal the leakage channel between the bottom edge of the inner door liner 122 and the lower end cover 123, thus preventing material leakage.

[0117] like Figures 4 to 6 As shown, in some optional embodiments, a plurality of through holes 1243 are provided on the second abutment portion 1242, and the through holes 1243 penetrate through the opposite sides of the abutment member 124.

[0118] The above technical solution has the following advantages or beneficial effects: it ensures that the areas on both sides of the abutment 124 and between the abutment 124 and the inner liner 122, which are most likely to trap air and form foam dead corners, can also be fully filled by the foaming material, thereby improving the filling effect of the foaming material, enhancing the foaming quality of the door body 120, and improving the overall thermal insulation performance of the door body 120.

[0119] In addition, it should be noted that due to certain tolerances in the manufacturing process of the inner door liner 122 and the lower end cover 123, gaps may occur when the two are assembled. Even if there are no gaps and they fit together perfectly, they may easily fall off. Therefore, foaming can be used, that is, the bonding effect of foaming material can be used. During foaming, the foaming material can be filled between the abutment 124 and the inner door liner 122 through multiple through holes 1243, thereby improving the connection strength between the abutment 124 and the inner door liner 122 and extending the service life of the door body 120.

[0120] Figure 8 for Figure 7 A magnified view of a portion of point III.

[0121] like Figure 7 and Figure 8 As shown, in some optional embodiments, the lower end cap 123 further comprises:

[0122] The connecting part 1231 extends along the direction facing the door shell 121, and there is an angle between the extending direction of the connecting part 1231 and the extending direction of the abutment 124;

[0123] Along the width direction of the housing 110, at least one of the first abutting portion 1241 and the second abutting portion 1242 has a first gap with the connecting portion 1231.

[0124] The above technical solution has the following advantages or beneficial effects: the foaming material, through the first gap, fully fills every gap between the abutment 124 and the inner door liner 122. After curing, the foaming material firmly anchors the abutment 124 and the inner door liner 122 together, and its connection strength is far superior to simple physical abutment or screw connection, effectively resisting separation caused by various stresses.

[0125] Furthermore, the first gap ensures smooth flow of the foaming material. This, in turn, ensures that areas most prone to trapping air and forming foaming dead zones, such as the area behind the abutment 124 and the interface between the abutment 124 and the inner liner 122, are kept dry, thus obtaining a high-quality foaming layer with consistent insulation performance.

[0126] In some embodiments, a first gap exists between the first abutting portion 1241 and the connecting portion 1231; or, a first gap exists between the second abutting portion 1242 and the connecting portion 1231; or, both the first abutting portion 1241 and the second abutting portion 1242 have a first gap with the connecting portion 1231.

[0127] Furthermore, regarding the size of the first gap, this application again does not impose excessive restrictions, and it can be adjusted according to the actual situation.

[0128] Figure 9 This is a first-view exploded diagram of a third type of variable temperature door in a refrigerator provided in an embodiment of this application. Figure 10 for Figure 9 A magnified view of a portion of point IV. Figure 11 This is an exploded view of the third type of variable temperature door structure in a refrigerator provided in an embodiment of this application. Figure 12 This is a second-view exploded diagram of a third type of variable temperature door in a refrigerator provided in an embodiment of this application. Figure 13 for Figure 12 A magnified view of a portion of point V in the middle.

[0129] like Figures 9 to 13 As shown, in some optional embodiments, the first abutment portion 1241 is horizontal;

[0130] Along the depth direction of the housing 110, there is a second gap between the side wall of the first abutment portion 1241 and the lower side wall of the inner door liner 122.

[0131] The above technical solution has the following advantages or beneficial effects: Since the foaming material encounters resistance when expanding and flowing, this second gap reduces the flow resistance, ensuring that the foaming material can fill the corner between the abutment 124 and the arc-shaped inner liner before expanding and curing, thereby improving the connection strength between the abutment 124 and the inner liner 122 and extending the service life of the door 120.

[0132] The analysis is as follows: A wedge-shaped gap, or second gap, is formed between the horizontal first abutment 1241 and the lower side wall of the arc-shaped inner door liner 122, with a gradually changing cross-section in the depth direction of the box 110. When the foaming material is injected into the cavity from above, it flows downward and outward along the second gap until it reaches the gap between the abutment 124 and the inner door liner 122.

[0133] Furthermore, regardless of the minute manufacturing tolerances in the curvature of the inner door liner 122, this design ensures that the foaming material can be effectively filled through the second gap, enhancing the foaming quality of the door body 120 and improving the overall thermal insulation performance of the door body 120.

[0134] Figure 14This is an exploded schematic diagram of the fourth type of variable temperature door in a refrigerator provided in an embodiment of this application. Figure 15 for Figure 14 A magnified view of a portion of point VI in the middle.

[0135] like Figure 14 and Figure 15 As shown, in some alternative embodiments, a third gap exists between the first abutment portion 1241 and the bottom end of the lower end cover 123 along the height direction of the housing 110.

[0136] The above technical solution has the following advantages or beneficial effects: During foaming, the foaming material can be filled between the abutment 124 and the inner liner through the third gap. The foaming material is fully filled, which improves the filling effect of the foaming material, enhances the foaming quality of the door 120, enhances the bonding strength between the inner liner 122 and the lower end cover 123, and improves the overall thermal insulation performance of the door 120.

[0137] The analysis is as follows: During the foaming process, air is pushed to the highest point, while the liquid flows to the lowest point. Without a third gap, the area directly below the first contact part 1241 is the most likely place to trap air and form an unfillable cavity.

[0138] The third gap, acting as a flow channel at the lowest point, allows air to be smoothly expelled as the foam material rises, while ensuring that the most difficult-to-fill bottom area is occupied by the foam material. This guarantees the uniformity of the bottom insulation layer of the door 120 and improves the overall insulation performance of the door 120.

[0139] In some alternative embodiments, the first abutting portion 1241 and the second abutting portion 1242 are integrally formed.

[0140] The above technical solution has the following advantages or beneficial effects: by making the first abutting part 1241 and the second abutting part 1242 integrally formed, not only can the connection strength between the first abutting part 1241 and the second abutting part 1242 be improved, but also the seamless connection between the first abutting part 1241 and the second abutting part 1242 can be achieved, thereby reducing the risk of cracking at the connection position of the first abutting part 1241 and the second abutting part 1242.

[0141] In some embodiments, the first abutment portion 1241 and the second abutment portion 1242 are connected by an integral connection. In other embodiments, the first abutment portion 1241 and the second abutment portion 1242 may also be connected by other connection methods. As long as the connection method can fix the first abutment portion 1241 and the second abutment portion 1242, the purpose of this embodiment can be achieved. Here, the connection method of the first abutment portion 1241 and the second abutment portion 1242 is not limited.

[0142] The refrigerator provided in this application includes a cabinet having a cooling compartment; a door movably connected to the cabinet and configured to open and close the cooling compartment, the door having: a door shell located on the side of the door facing away from the cabinet; a door liner located on the side of the door facing the cabinet; and a lower end cover located at the bottom of the door, the lower end cover having: an abutment member along the depth direction of the cabinet, the abutment member abutting against the door liner and fixed to the side of the door liner facing the door shell.

[0143] The abutment component ensures the sealing of the connection between the inner door liner and the lower end cover, preventing material leakage, enhancing the foaming quality of the door body, and improving the overall thermal insulation performance of the door body. In addition, since the foamed material has a certain structural support function after curing, the bonding and support functions of the foamed material can be used to enhance the bonding strength between the inner door liner and the lower end cover, thereby improving the strength of the door body.
