[0065] In order to make the purpose, the embodiments and the advantages of the present application clearer, the following will combine the drawings in the exemplary embodiments of the present application to make a clear and complete description of the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0066] It should be noted that the brief description of the terms in the present application is only for the convenience of understanding the following described embodiments, and is not intended to limit the embodiments of the present application. Unless otherwise specified, these terms should be understood according to their ordinary and general meanings.

[0067] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclusive inclusion, for example, a product or device including a series of components does not have to be limited to the clearly listed components, but can include other components that are not clearly listed or inherent to these products or devices.

[0068] In the description of the present application, it needs to be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0069] The terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0070] In the description of the present application, it needs to be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0071] The heat insulation performance of the door body is crucial for the temperature maintenance of the refrigerator. Among them, the vacuum heat insulation plate has good heat insulation performance, and is applied to the refrigerator door body.

[0072] In the related art, the setting of the vacuum heat insulation plate along the height direction of the door body is limited, so that the utilization rate of the vacuum heat insulation plate is low; and the heat insulation and heat preservation performance at the handle is poor, which leads to easy condensation at the handle.

[0073] In some door bodies of the refrigerator, the vacuum heat insulation plate extends to the upper end cover and the lower end cover of the door body at both ends along the height direction, and the vacuum heat insulation plate is located inside at the handle, which improves the heat insulation performance at the handle. Although the vacuum heat insulation plate has a large area, the two sides of the vacuum heat insulation plate have a small gap, which leads to poor flowability of the foaming material, easy to produce bubble structure, and affects the heat preservation performance of the door body.

[0074] In some door bodies of the refrigerator, the vacuum heat insulation plate is fixed on the door liner, and only a gap is provided between the vacuum heat insulation plate and the door panel to fill the foaming material. Although the setting of the vacuum heat insulation plate does not affect the flowability of the foaming material, the area of the vacuum heat insulation plate is reduced, and the cost performance is reduced; and the heat preservation performance at the handle is poor, which is easy to condense.

[0075] Therefore, the door body of the refrigerator provided in the embodiments of the present application uses the surface characteristics of the vacuum heat insulation plate to attach the vacuum heat insulation plate to the door panel, so that the foaming material is formed between the vacuum heat insulation plate and the door liner without affecting the flowability of the foaming material; and a vacuum heat insulation plate with a larger area can be arranged as much as possible to improve the performance-price ratio of the vacuum heat insulation plate.

[0076] In addition, the metal layer of the vacuum heat insulation plate is attached to the door panel, and the heat of external air is transmitted to the handle part in the form of heat conduction through the metal layer, thereby reducing the possibility of condensation of the handle part. The top end of the vacuum heat insulation plate is attached to the upper cover plate forming the handle part, which is beneficial to improve the heat insulation and heat preservation performance of the handle part and reduce the amount of cold transferred to the handle part.

[0077] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0078] First of all, it needs to be pointed out that in the embodiments of the present application, when the door body of the refrigerator is in a closed state, the width direction of the door body is consistent with the width direction of the refrigerator, the thickness direction of the door body is consistent with the depth direction of the refrigerator, and the height direction of the door body is consistent with the height direction of the refrigerator. The width direction of the refrigerator corresponds to the X-axis direction in the figure, the depth direction of the refrigerator corresponds to the Y-axis direction in the figure, and the height direction of the refrigerator corresponds to the Z-axis direction in the figure.

[0079] In combination Figure 1 Some embodiments of the present application provide a refrigerator, which includes a cabinet 100 that can be configured to form a refrigeration compartment 101 with an opening for storing items.

[0080] The refrigeration compartment 101 can be provided in plurality to expand the storage space. According to the different storage temperatures of the refrigeration compartment 101, the refrigeration compartment 101 can include at least one refrigeration compartment and at least one freezing compartment. Among them, the internal temperature of the refrigeration compartment can be maintained at about 0℃ to 5℃ to store items in a refrigeration mode; the internal temperature of the freezing compartment can be maintained at about -30℃ to 0℃ to store items in a freezing mode.

[0081] In some possible implementations, at least one refrigeration compartment 101 can also be provided as a vacuum chamber or a temperature-variable chamber, etc., and the embodiments of the present application will not be described here.

[0082] Exemplarily, the refrigerator compartment 101 can be provided with two, and the two refrigerator compartments 101 can be arranged in a vertical direction in a stacked manner. The two refrigerator compartments 101 can be arranged in a horizontal direction in a side-by-side manner. One of the two refrigerator compartments 101 can be arranged as a refrigeration compartment, and the other one of the two refrigerator compartments 101 can be arranged as a freezer compartment.

[0083] Exemplarily, the refrigerator compartment 101 can be provided with three, and the three refrigerator compartments 101 can be arranged in a vertical direction in a stacked manner.

[0084] In some embodiments, the cabinet 100 can include a cabinet inner container and a cabinet outer shell. The cabinet inner container can be configured with the refrigerator compartment 101. The cabinet outer shell can be connected to the outside of the cabinet inner container to form the appearance of the refrigerator. The cabinet 100 can further include a cabinet thermal insulation layer, which can be arranged between the cabinet inner container and the cabinet outer shell. The cabinet thermal insulation layer can thermally insulate the refrigerator compartment 101 to minimize heat exchange between the refrigerator compartment 101 and the outside of the refrigerator, thereby helping to ensure the refrigeration effect of the refrigerator.

[0085] The refrigerator of the embodiments of the present application can further include a refrigeration system for providing cold energy to the refrigerator compartment 101. Exemplarily, the refrigeration system can be arranged in the cabinet 100. The refrigeration system can include a compressor, a condenser, a throttling device, and an evaporator connected in a circulation manner.

[0086] When the refrigeration system is running, the compressor compresses refrigerant vapor to generate high-temperature and high-pressure refrigerant vapor and delivers the refrigerant vapor to the condenser. The condenser liquefies the high-temperature and high-pressure refrigerant vapor to generate high-temperature and low-pressure refrigerant liquid and delivers the refrigerant liquid to the throttling device. The throttling device depressurizes the refrigerant liquid to change the high-pressure and low-temperature refrigerant liquid into low-pressure and low-temperature refrigerant liquid and delivers the refrigerant liquid to the evaporator. The evaporator receives the low-pressure and low-temperature refrigerant liquid and causes the refrigerant liquid to boil under isobaric conditions to absorb heat and vaporize to form refrigerant vapor, thereby reducing the temperature in the refrigerator compartment 101.

[0087] Continuing to refer to Figure 1 and Figure 2 , the refrigerator of the embodiments of the present application can further include a door body 200 for opening and closing the refrigerator compartment 101.

[0088] In some embodiments, the side of the door body 200 facing the refrigeration compartment is provided with a door shelf to increase the storage space of the refrigerator. The door shelf has a storage cavity opening upward to store articles.

[0089] Referring to Figure 1 and Figure 2 , in some embodiments, the door body 200 is rotatably connected to the cabinet 100 to open or close the refrigerator compartment 101.

[0090] Each refrigeration compartment 101 can correspondingly be provided with one door body 200; or, each refrigeration compartment 101 can correspondingly be provided with two door bodies 200, and the two door bodies 200 can rotate in opposite directions to open or close the refrigeration compartment 101.

[0091] Referring to Figure 3 and Figure 4 In some embodiments, the refrigerator can further include at least one drawer 300 installed in the refrigeration compartment 101 in a pullable manner along the depth direction of the refrigerator. The outer end of the drawer 300 is fixed with a door body 200, and the door body 200 moves with the pullable movement of the drawer 300 to open or close the refrigeration compartment 101.

[0092] Referring to Figure 5 and Figure 6 In some embodiments, the door body 200 includes a door liner 210 facing the refrigeration compartment 101.

[0093] In some embodiments, the door body 200 can include a sealing member 250 arranged on the side of the door liner 210 facing the refrigeration compartment 101, and the sealing member 250 can be clamped to the edge of the door liner 210. When the door body 200 closes the refrigeration compartment 101, the sealing member 250 is clamped between the door liner 210 and the cabinet 100, so that the door body 200 seals the refrigeration compartment 101 and reduces the leakage of cold air in the refrigeration compartment 101.

[0094] In some embodiments, the door body 200 can include a door panel 220 fixed to the outer side of the door liner 210 to form the appearance of the door body 200.

[0095] The door panel 220 and the door liner 210 have a gap therebetween in the thickness direction of the door body 200 to install the heat preservation structure of the door body 200. In some door bodies 200, the gap between the door panel 220 and the door liner 210 can reserve installation space for control devices on the door body 200.

[0096] In some embodiments, the door body 200 can include a first end cover 230 fixed to the top end or the bottom end between the door liner 210 and the door panel 220. In the drawings of the embodiments of the present application, the first end cover 230 is fixed to the top end between the door liner 210 and the door panel 220 as an example for illustration and description. In some embodiments, the first end cover 230 can also be fixed to the bottom end between the door liner 210 and the door panel 220.

[0097] The first end cover 230 can be clamped or bonded to the door liner 210, and the first end cover 230 can be bonded or clamped to the door panel 220, and the fixing mode is stable and reliable.

[0098] The connection structure of the first end cover 230 and the door liner 210 is located on the side of the door liner 210 facing the door panel 220, and the connection structure of the first end cover 230 and the door panel 220 is located on the side of the door panel 220 facing the door liner 210. In this way, on the side of the door liner 210 facing the refrigeration compartment 101 and on the side of the door panel 220 facing away from the refrigeration compartment 101, no connection structure is exposed, which helps to improve the appearance of the door body 200 and can avoid the influence of the connection structure on the sealing of the door body 200.

[0099] In some possible implementations of the present application, the first end cover 230 is configured to form a recessed handle portion 2301, which facilitates user gripping to open or close the door body 200.

[0100] In some embodiments, the door body 200 can further include a vacuum insulation panel 240 fixed between the door liner 210 and the door panel 220.

[0101] The vacuum insulation panel 240 (Vacuum Insulation Panel) can be made of glass fibers or aerogels, etc., and is coated with a thin film with high air tightness to form a surface layer to maintain the vacuum state inside to provide good thermal insulation performance.

[0102] The vacuum insulation panel 240 can further include an adsorbent material inside the surface layer, which can adsorb residual moisture and air inside, thereby further improving the vacuum degree of the vacuum insulation panel 240 and improving the thermal insulation performance of the vacuum insulation panel 240.

[0103] In some embodiments, referring to Figure 7 and Figure 8 , the vacuum insulation panel 240 can include a thermal insulation panel body 242 and an edge sealing 243 provided at the edge of the thermal insulation panel body 242, wherein the thermal insulation panel body 242 is formed by a core 245 inside and a surface layer coated outside the core 245, and the surface layer is sealed at the edge of the core 245 to form the edge sealing 243 to ensure the vacuum degree of the thermal insulation panel body 242.

[0104] The surface layer can include a metal layer 241, which can be an aluminum film. The aluminum film has high strength and good thermal conductivity, and its cost is low. The metal layer 241 can include a substrate and a metal film formed by evaporation on the substrate, and a protective layer can be further formed on the outer surface of the metal film to increase the durability and chemical corrosion resistance of the surface layer.

[0105] The surface layer can further include a polymer layer 244, which can include polyurethane, polyester (PET), polypropylene (PP), and nylon (PA), etc. These materials provide mechanical strength and flexibility. Exemplarily, the surface layer can include a polyurethane foam layer.

[0106] In some embodiments of the present application, the vacuum insulation plate 240 is attached to the door panel 220 to ensure that there is no gap between the vacuum insulation plate 240 and the door panel 220, and to ensure the heat insulation performance of the door body 200.

[0107] In some embodiments of the present application, at least one of the two surface layers of the vacuum insulation plate 240 is a metal layer 241, for example, one of the two surface layers of the vacuum insulation plate 240 is a metal layer 241, and the other is a polymer layer 244.

[0108] In some other embodiments of the present application, the two surface layers of the vacuum insulation plate 240 can both be metal layers 241.

[0109] In some embodiments of the present application, the vacuum insulation plate 240 is attached to the door panel 220, which can not only fix the vacuum insulation plate 240 in the space between the door panel 220 and the door shell, but also ensure that the vacuum insulation plate 240 is attached to the door panel 220.

[0110] In addition, the vacuum insulation plate 240 is attached to the door panel 220 in advance, and then the door panel 220 and the door liner 210 are assembled, which does not affect the assembly of the door panel 220 and other components, and is beneficial to ensuring the assembly efficiency of the door body 200.

[0111] Of course, in some implementations, the vacuum insulation plate 240 can also be fixed between the door panel 220 and the door shell by a fixing structure, so that the vacuum insulation plate 240 is attached to the door panel 220. The fixing structure can be a buckle, a bracket or other structure arranged between the door panel 220 and the door shell.

[0112] Referring to Figure 9 and Figure 10 In some embodiments, the vacuum insulation plate 240 has a space with the door liner 210 to reserve space for electrical components and other heat preservation structures on the door body 200.

[0113] In some embodiments, the door body 200 can also include a foaming member between the vacuum insulation plate 240 and the door liner 210.

[0114] For example, the foaming member can be a polyurethane foaming layer, which is beneficial to improving the heat preservation performance of the door body 200.

[0115] In the embodiments of the present application, the vacuum insulation plate 240 is attached to the door panel 220, so that the foaming member is located between the vacuum insulation plate 240 and the door liner 210, and the arrangement of the vacuum insulation plate 240 does not affect the flow of the foaming material, so that the foaming member can better fill between the vacuum insulation plate 240 and the door liner 210, and the possibility of incomplete filling and bubble hole formation is reduced.

[0116] In some embodiments of the present application, the metal layer 241 of the vacuum insulation plate 240 is attached to the door panel 220, for example, the metal layer 241 of the vacuum insulation plate 240 is bonded to the door panel 220.

[0117] In addition, one end of the vacuum insulation plate 240 along the height direction of the door body 200 is attached to the first end cover 230.

[0118] Through the above arrangement, one end of the vacuum insulation plate 240 along the height direction is attached to the first end cover 230, and the metal layer 241 of the vacuum insulation plate 240 is attached to the door panel 220, so that the heat of the external space is transmitted to the handle part 2301 in the form of heat conduction through the metal layer 241, which is beneficial to improve the surface temperature of the handle part 2301 and prevent the handle part 2301 from dewing. In addition, the vacuum insulation plate 240 is attached to the first end cover 230, which can improve the heat insulation and heat preservation performance of the first end cover 230 and reduce the possibility of cold air in the refrigeration compartment 101 being transmitted outward through the handle part 2301, which is beneficial to ensure the heat preservation performance of the handle part.

[0119] Therefore, the door body 200 of the embodiment of the present application attaches the vacuum insulation plate 240 to the side of the door panel 220 facing the door liner 210, so that the vacuum insulation plate 240 can be arranged in a larger area, and a foaming member is formed between the vacuum insulation plate 240 and the door liner 210. The arrangement of the vacuum insulation plate 240 does not affect the flow of foaming material, and the double-layer heat insulation and heat preservation of the vacuum insulation plate 240 and the foaming member are utilized, which is beneficial to improve the overall heat preservation performance of the door body 200. The metal surface layer of the vacuum insulation plate 240 is attached to the door panel 220, so that the heat of the external space is transmitted to the handle part 2301 in the form of heat conduction through the metal layer 241, which is beneficial to improve the surface temperature of the handle part 2301; one end of the vacuum insulation plate 240 along the height direction of the door body 200 is attached to the first end cover 230, which reduces the cold quantity of the refrigeration compartment 101 transmitted to the handle part 2301 and further ensures the heat insulation and heat preservation performance of the handle part 2301, thereby reducing the possibility of water droplets being condensed on the handle part 2301.

[0120] Therefore, on the basis of ensuring the overall heat preservation performance of the door body 200, on the one hand, the metal surface layer of the vacuum insulation plate 240 is attached to the door panel 220 to transmit the heat of the external space to the handle part 2301 through the metal layer 241 and to concentrate the external heat on the handle part 2301 as much as possible; on the other hand, the vacuum insulation plate 240 is attached to the first end cover 230 to improve the heat insulation performance of the handle part 2301 and reduce the cold quantity of the refrigeration compartment 101 transmitted to the handle part 2301. Through the above two aspects, the surface temperature of the handle part 2301 is ensured to be above the dew point temperature, thereby preventing the handle part 2301 from dewing.

[0121] In some embodiments of the present application, the closed foldable vacuum insulation plate 240 can reduce the space occupied by the sealing edge 243.

[0122] In combination Figure 10 And Figure 11 , the part of the sealing edge 243 along one side of the height direction is folded towards the side away from the metal layer 241 and adheres to the insulation plate body 242.

[0123] In the orientation shown in Figure 11 , the metal layer 241 of the vacuum insulation plate 240 adheres to the door panel 220, and the sealing edge 243 is folded towards the side of the door liner 210 and adheres to the insulation plate body 242.

[0124] After the sealing edge 243 is folded, it can be bonded with the insulation plate body 242 so that the sealing edge 243 adheres to the insulation plate body 242 after being folded.

[0125] After the sealing edge 243 is folded and adheres to the insulation plate body 242, it can be understood that the sealing edge 243 not only adheres to the end of the insulation plate body 242 along the height direction, but also adheres to the surface of the insulation plate body 242 along the thickness direction, which can make the structure of the vacuum insulation plate 240 compact and avoid the sealing edge 243 from being raised, affecting the flowability of the foaming material.

[0126] Among them, the insulation plate body 242 and the sealing edge 243 adhering to the insulation plate body 242 are adhered to the first end cover 230, and the insulation plate body 242 and the sealing edge 243 adhering to the insulation plate body 242 can be bonded with the first end cover 230, so that the first end cover 230 adheres to the folded sealing edge 243. Or, after the metal layer 241 of the insulation plate body 242 adheres to the door panel 220, the folded sealing edge 243 abuts against the first end cover 230, so that the sealing edge 243 adhering to the insulation plate body 242 adheres to the first end cover 230.

[0127] Through the above arrangement, the sealing edge 243 of the vacuum insulation plate 240 is folded and adheres to the insulation plate body 242, reducing the installation space occupied by the sealing edge 243 and also reducing the influence of the sealing edge 243 being raised on the flowability of the foaming material. The folded sealing edge 243 adheres to the first end cover 230, which can ensure the heat insulation and heat preservation performance at the first end cover 230. Since one side of the insulation plate body 242 and the sealing edge 243 is the metal layer 241, the sealing edge 243 is folded away from the metal layer 241, so that the metal layer 241 at the sealing edge 243 adheres to the first end cover 230, which can ensure that the metal layer 241 at the insulation plate body 242 and the metal layer 241 at the sealing edge 243 transfers heat to the handle part 2301 of the first end cover 230, reducing the possibility of condensation at the handle.

[0128] Continue to refer to Figure 11In some embodiments of the present application, the first end cover 230 comprises a first plate portion 231 fixedly connected with the door panel 220, and the first plate portion 231 is opposite to the door panel 220 in the thickness direction. For example, the first plate portion 231 can be clamped with the door panel 220, and the connection manner is simple and easy to assemble.

[0129] The first end cover 230 can comprise a second plate portion 232 fixedly connected with the door liner 210. Part of the second plate portion 232 is opposite to the first plate portion 231 in the thickness direction.

[0130] The first end cover 230 can comprise a third plate portion 233 connected to the same end of the first plate portion 231 and the second plate portion 232 in the height direction. Figure 11 In the illustrated embodiment, the third plate portion 233 is connected to the bottom end of the first plate portion 231 and the second plate portion 232 in the height direction. The third plate portion 233, the second plate portion 232, and the first plate portion 231 enclose a handle portion 2301.

[0131] In some embodiments, referring to Figure 12 and Figure 13 , the second plate portion 232 is opposite to the door liner 210 in the thickness direction. In this way, the second plate portion 232 and the door liner 210 can have a space therebetween to accommodate a foaming piece, thereby ensuring the heat insulation and heat preservation performance of the second plate portion 232.

[0132] The first end cover 230 can comprise a fourth plate portion 234 connected to one end of the second plate portion 232 away from the third plate portion 233, and the fourth plate portion 234 can be arranged parallel to a horizontal plane, which can be a plane determined by the width direction and the depth direction of the refrigerator.

[0133] The first end cover 230 can comprise a fifth plate portion 235 connected to one end of the fourth plate portion 234 away from the second plate portion 232, and the fifth plate portion 235 has a space with the second plate portion 232 in the thickness direction of the door body 200. The fifth plate portion 235 can be fixedly connected with the door liner 210, so that the second plate portion 232 is indirectly connected with the door liner 210 through the fourth plate portion 234 and the fifth plate portion 235.

[0134] In some possible implementations, the second plate portion 232, the third plate portion 233, the fourth plate portion 234, and the fifth plate portion 235 are an integral piece integrally formed, and the integral piece is fixedly connected with the first plate portion 231, and the connection manner can be clamping, bonding, or the like. In this way, the complexity of forming the first end cover 230 can be reduced.

[0135] In some embodiments, along the width direction of the door body 200, from the side far away from the hinged side to the side close to the hinged side, the size of the end of the third plate part 233 close to the hinged side along the thickness direction of the door body 200 gradually decreases to zero, so that the second plate part 232 is connected to the first plate part 231 close to the hinged side of the door body 200, so that the fourth plate part 234 has a large size along the thickness direction of the door body 200 close to the hinged side, facilitating the arrangement of the hinged structure 236. The hinged structure 236 is used to mount a hinge assembly, and the hinge assembly connects the door body 200 and the cabinet 100, so that the door body 200 can rotate relative to the cabinet 100.

[0136] In combination Figure 14 The first end cover 230 can further include two end plate parts 237, one of which is fixed to the first plate part 231, the second plate part 232, the third plate part 233, the fourth plate part 234 and the fifth plate part 235 at one end along the width direction of the door body 200; the other end plate part 237 is fixed to the first plate part 231, the second plate part 232, the fourth plate part 234 and the fifth plate part 235 at the other end along the width direction of the door body 200.

[0137] Referring to Figure 15 In some embodiments, the first end cover 230 can include a reinforcing plate 238 arranged between the second plate part 232 and the fifth plate part 235, and the reinforcing plate 238 can be connected to the second plate part 232, the fourth plate part 234 and the fifth plate part 235 respectively, to improve the structural strength and stability of the first end cover 230.

[0138] In some possible implementations of the present application, the reinforcing plate 238 can be provided in multiple, and the multiple reinforcing plates 238 can be arranged at intervals along the width direction of the door body 200, to further improve the structural strength and stability of the first end cover 230.

[0139] Continuing to refer to Figure 11 In some embodiments of the present application, the third plate part 233 is attached to the vacuum heat insulation plate 240. Specifically, the folded edge 243 is attached to the third plate part 233, and such arrangement can ensure that the metal layer 241 extends from the door panel 220 to the handle, not only improving the temperature of the first plate part 231, but also improving the temperature of the third plate part 233, to avoid condensation at the handle part 2301.

[0140] Continuing to refer to Figure 11 and Figure 13 In some embodiments, a metal adhesive tape 280 is attached to the third plate part 233, and the metal adhesive tape 280 is located between the third plate part 233 and the vacuum heat insulation plate 240.

[0141] The metal adhesive tape 280 can be attached to the third plate part 233, and the connection is stable and reliable.

[0142] The metal adhesive tape 280 can be an aluminum foil adhesive tape, a copper foil adhesive tape, a stainless steel adhesive tape, etc. In some embodiments of the present application, the metal adhesive tape 280 is an aluminum foil adhesive tape, which has good heat conduction performance.

[0143] Of course, the third plate portion 233 can also be provided with a metal film by bonding, and the metal film and the bonding layer of the metal film form the metal adhesive tape 280. In the embodiments of the present application, the metal adhesive tape 280 is directly used, which is stable and reliable in bonding and convenient to assemble.

[0144] In the embodiments of the present application, the metal adhesive tape 280 is attached to the third plate portion 233, and the metal adhesive tape 280 is located between the third plate portion 233 and the vacuum heat insulation plate 240, which can diffuse the heat transferred from the door panel 220 and further prevent the handle portion 2301 from condensation.

[0145] In some embodiments of the present application, the metal adhesive tape 280 extends to the inner side of the second plate portion 232. The inner side of the second plate portion 232 is the side of the second plate portion 232 facing the door liner 210.

[0146] In the embodiments of the present application, the metal adhesive tape 280 extends to the inner side of the second plate portion 232, so that the heat transferred from the metal layer 241 to the third plate portion 233 can be transferred to the second plate portion 232 through the metal adhesive tape 280, which can diffuse the heat and further prevent the handle portion 2301 from condensation.

[0147] In combination with Figure 15 In some embodiments, the metal adhesive tape 280 is arranged at the plane of the second plate portion 232 and the third plate portion 233, and the metal adhesive tape 280 does not extend to the inclined surface of the second plate portion 232 and the third plate portion 233, so as to facilitate the bonding of the metal adhesive tape 280 and avoid affecting the heat conduction effect due to poor bonding of the metal adhesive tape 280.

[0148] Of course, the metal adhesive tape 280 can also extend to the inclined surface of the second plate portion 232 and the third plate portion 233, for example, the metal adhesive tape 280 can extend to both ends of the second plate portion 232 and the third plate portion 233 along the width direction of the door body 200, so as to expand the arrangement area of the metal adhesive tape 280 and improve the heat conduction performance.

[0149] In combination with Figure 7 In some embodiments, the part of the edge 243 on the other side in the height direction is bent towards the side away from the metal layer 241 and attached to the heat insulation plate body 242. For example, the edge 243 is bonded to the heat insulation plate body 242 after being folded. Such arrangement can further reduce the installation space occupied by the vacuum heat insulation plate 240 and avoid the edge 243 of the vacuum heat insulation plate 240 from being raised to affect the flow of the foaming material.

[0150] In some embodiments, the edge seal 243 is folded towards the side away from the metal layer 241 along the two sides of the door body 200 in the width direction, and is attached to the thermal insulation plate body 242. For example, the edge seal 243 is adhered to the thermal insulation plate body 242 after being folded. Such an arrangement can further reduce the installation space occupied by the vacuum thermal insulation plate 240, and avoid the edge seal 243 of the vacuum thermal insulation plate 240 from being raised to affect the flow of the foaming material.

[0151] With reference to the foregoing Figure 6 In some embodiments of the present application, the door body 200 further comprises a second end cover 260 fixed between the door liner 210 and the door panel 220, and the second end cover 260 is opposite to the first end cover 230 in the height direction and has a spacing therebetween.

[0152] When the first end cover 230 is fixed to the top end of the door liner 210 and the door panel 220, the second end cover 260 is fixed to the bottom end of the door liner 210 and the door panel 220. The second end cover 260 can be snap-connected or adhered to the door liner 210, and the second end cover 260 can be snap-connected or adhered to the door panel 220.

[0153] In some embodiments, the other end of the vacuum thermal insulation plate 240 in the height direction has a spacing from the second end cover 260, so as to avoid interference between the second end cover 260 and the vacuum thermal insulation plate 240.

[0154] For example, the spacing between the other end of the vacuum thermal insulation plate 240 in the height direction and the second end cover 260 can be 50 mm, but this is not a size limitation of the spacing between the vacuum thermal insulation plate 240 and the second end cover 260.

[0155] In some embodiments of the present application, the door body 200 can further comprise two side end covers 270 respectively located on the two sides of the door panel 220 and the door liner 210 in the width direction of the door body 200 and between the door panel 220 and the door liner 210; the two side end covers 270 are respectively fixedly connected to the first end cover 230 and the second end cover 260 in the height direction of the door body 200; and the two side end covers 270 are respectively fixed to the door panel 220 and the door liner 210 in the thickness direction of the door body 200.

[0156] In combination with Figure 9 and Figure 16 , the two sides of the vacuum thermal insulation plate 240 in the width direction of the door body 200 have a spacing from the two side end covers 270, so as to avoid interference between the two side end covers 270 and the vacuum thermal insulation plate 240.

[0157] Exemplarily, the interval between the vacuum insulation plate 240 and the side end cover 270 along the width direction of the door body 200 can be 50 mm, but this is not a size limitation of the interval between the vacuum insulation plate 240 and the second end cover 260.

[0158] The door body 200 of some embodiments of the present application is configured to enclose a specific cavity by the second end cover 260 and the two end covers, the first end cover 230, the door panel 220 and the door liner 210, at least for accommodating the vacuum insulation plate 240 and the foamed member, and the interval between the vacuum insulation plate 240 and the second end cover 260 and the interval between the vacuum insulation plate 240 and the side end cover 270 are provided to avoid the interference between the second end cover 260 and the side end cover 270 and the vacuum insulation plate 240.

[0159] In combination Figure 1 and Figure 2 In some embodiments, the above-mentioned door body 200 structure can be applied to a rotatable door body 200, which is hinged to the cabinet 100 by the first end cover 230, so that the door body 200 can be rotated relative to the cabinet 100 to open or close the refrigeration compartment 101. At this time, the second end cover 260 is also hinged to the cabinet 100 to ensure the reliability and stability of the hinge between the door body 200 and the cabinet 100.

[0160] In combination Figure 3 and Figure 4 In other embodiments, the above-mentioned door body 200 structure can be fixedly connected to the outside of the drawer 300, and the door body 200 can be pulled out along the depth direction of the refrigerator together with the drawer 300 to open or close the refrigeration compartment 101.
