[0071] In the description of the present application, it should be noted that unless specifically defined and limited, the terms "mount", "connect", "connect" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, and it can be connected 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.

[0072] 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.

[0073] In the related art, the vacuum heat insulation plate is bonded to the door panel of the door body, for example, the vacuum heat insulation plate is bonded to the door panel by double-sided adhesive, hot melt adhesive, etc., and then the vacuum heat insulation plate is bonded firmly by using external force stamping; and then foaming filling is performed. However, there is a problem of poor bonding between the vacuum heat insulation plate and the door panel, which causes bubbles between the vacuum heat insulation plate and the door panel, uneven appearance of the door panel, or shrinkage, etc., affecting the appearance of the door panel. Moreover, a special pasting process needs to be added for the assembly of the door body, and the vacuum heat insulation plate has a large area, the bonding time is long, which affects the production efficiency of the door body.

[0074] In some door bodies, a bracket is fixed on the door panel to fix the vacuum heat insulation plate on the bracket. However, the bracket is in contact with the door panel, and the door panel is still deformed, affecting the appearance of the door panel. Moreover, the connection between the vacuum heat insulation plate and the bracket is easy to loosen, affecting the yield of the door body.

[0075] Therefore, in the embodiments of the present application, the vacuum heat insulation plate is hung on the upper end cover of the door body, there is a gap between the vacuum heat insulation plate and the door panel, and there is a gap between the vacuum heat insulation plate and the inner liner of the door, and the foaming material is filled on both sides of the vacuum heat insulation plate. In this way, the door panel and the inner liner are both in contact with the foaming material, solving the technical problems of uneven surface of the door panel, sink marks, etc. caused by bonding of the vacuum heat insulation plate and the door panel.

[0076] Moreover, the vacuum heat insulation plate is directly hung on the upper end cover of the door body, and compared with the bonding mode, the hanging and mounting mode in the embodiments of the present application is beneficial to improve the assembly efficiency of the door body, and further improve the processing efficiency of the door body.

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

[0078] Firstly, it should be noted 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, and the cabinet 100 can be configured to form a refrigeration compartment 101 with an opening for storing articles.

[0080] The refrigeration compartment 101 can be provided in plurality to expand the storage space. According to 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 articles in a refrigeration mode; the internal temperature of the freezing compartment can be maintained at about -30℃ to 0℃ to store articles 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 variable-temperature chamber, etc., and the embodiments of the present application will not be described again.

[0082] Exemplarily, the refrigeration compartment 101 can be provided with two, and the two refrigeration compartments 101 can be provided in a vertical direction. The two refrigeration compartments 101 can be provided side by side in a horizontal direction. One of them can be provided as a refrigeration compartment, and one of them can be provided as a freezing compartment.

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

[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 refrigeration 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 refrigeration compartment 101 to minimize heat exchange between the refrigeration 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 refrigeration 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 convert the high-pressure and low-temperature refrigerant liquid into low-pressure and low-temperature refrigerant liquid and deliver the refrigerant liquid to the evaporator. The evaporator receives the low-pressure and low-temperature refrigerant liquid and causes it to boil under isobaric conditions to absorb heat and vaporize to form refrigerant vapor, thereby reducing the temperature in the refrigeration 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 refrigeration 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 items.

[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 refrigeration compartment 101.

[0090] Each refrigeration compartment 101 can correspond to one door body 200; or each refrigeration compartment 101 can correspond to 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 4In some embodiments, the refrigerator can further include at least one drawer 300 installed in the refrigerating compartment 101 in a pullable manner along the depth direction of the refrigerator. An outer end of the drawer 300 is fixed with a door body 200, and the door body 200 moves with the drawer 300 to open or close the refrigerating compartment 101.

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

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

[0094] In some embodiments, the door body 200 can include a door panel 220 fixed to the outside 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 along the thickness direction of the door body 200 to install the thermal insulation 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] Continuing to refer to Figure 5 The door body 200 of the embodiments of the present application can further include a side coaming 230 fixed between the door liner 210 and the door panel 220 and surrounding the edges of the door liner 210 and the door panel 220.

[0097] The side coaming 230, the door liner 210 and the door panel 220 together enclose a closed space for at least accommodating the thermal insulation structure of the door body 200.

[0098] In some embodiments, the side coaming 230 can include an upper end cover 231 located at the top end of the door panel 220 and the door liner 210.

[0099] The upper end cover 231 can be clamped or bonded to the door panel 220, and the upper end cover 231 can be bonded or clamped to the door liner 210, so that the fixing mode of the upper end cover 231 is stable and reliable.

[0100] The connection structure of the upper end cover 231 and the door inner liner 210 is located on the side of the door inner liner 210 facing the door panel 220, and the connection structure of the upper end cover 231 and the door panel 220 is located on the side of the door panel 220 facing the door inner liner 210. In this way, no connection structure is exposed on the side of the door inner liner 210 facing the refrigeration compartment 101 and on the side of the door panel 220 facing away from the refrigeration compartment 101, 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.

[0101] In some possible implementations, the upper end cover 231 can also be concave downward to form a handle portion, which facilitates the user to hold and open or close the refrigeration compartment 101.

[0102] In some embodiments, the side surrounding plate 230 can include a lower end cover 232 located at the bottom end of the door panel 220 and the door inner liner 210. The lower end cover 232 is opposite to the upper end cover 231 along the height direction of the door body 200 and has a spacing,

[0103] The lower end cover 232 can be connected or bonded to the door panel 220, and the lower end cover 232 can be connected or bonded to the door inner liner 210, so that the fixing mode of the lower end cover 232 is stable and reliable.

[0104] In some embodiments, the side surrounding plate 230 can include two side end covers 233 located on both sides of the door panel 220 along the width direction of the door body 200. The two side end covers 233 are located between the door panel 220 and the door inner liner 210. The two side end covers 233 are fixedly connected to the upper end cover 231 and the lower end cover 232 at both ends along the height direction of the door body 200, and the two side end covers 233 are fixed to the door panel 220 and the door inner liner 210 at both sides along the thickness direction of the door body 200.

[0105] In some possible embodiments of the present application, the two side end covers 233 and the door panel 220 are an integral part formed integrally, so that there is a connection gap between the door panel 220 and the side end cover 233, which not only improves the heat preservation performance of the door body 200, but also helps to improve the appearance of the door body 200.

[0106] Continuing to refer to Figure 5 In some embodiments of the present application, the door body 200 can also include a vacuum insulation panel 240 fixed between the door inner liner 210 and the door panel 220.

[0107] The vacuum insulation panel 240 (Vacuum Insulation Panel) can be made of glass fiber or aerogel, etc., and is coated with a film with high airtightness to form a surface layer to maintain the vacuum state inside to provide good heat insulation performance.

[0108] The vacuum heat insulation plate 240 can further include an adsorbing material inside the surface layer, which functions to adsorb residual moisture and air inside, so as to further improve the vacuum degree of the vacuum heat insulation plate 240, and thus improve the heat insulation performance of the vacuum heat insulation plate 240.

[0109] The vacuum heat insulation plate 240 is fixed to the side surrounding plate 230, and can be fixed to at least one of the upper end cover 231, the lower end cover 232, and the two side end covers 233.

[0110] Exemplarily, the vacuum heat insulation plate 240 can be fixed to the upper end cover 231.

[0111] Exemplarily, the vacuum heat insulation plate 240 can be fixed to one of the side end covers 233.

[0112] Exemplarily, the vacuum heat insulation plate 240 can be fixedly connected with the upper end cover 231 and the lower end cover 232 respectively.

[0113] The vacuum heat insulation plate 240 can be fixed to the side surrounding plate 230 in various ways, for example, the vacuum heat insulation plate 240 is clamped to the side surrounding plate 230, and the connection is stable; for another example, the vacuum heat insulation plate 240 is hung on the side surrounding plate 230, and the assembly is simple, which is conducive to improving the assembly efficiency of the door body 200.

[0114] In some possible implementations of the present application, the vacuum heat insulation plate 240 is hung on the upper end cover 231, which can not only fix the vacuum heat insulation plate 240 between the door liner 210 and the door shell, but also make the installation mode of the vacuum heat insulation plate 240 simple, which is conducive to improving the assembly efficiency of the door body 200.

[0115] Exemplarily, the upper end cover 231 and the vacuum heat insulation plate 240 form clamping hooks respectively, and the vacuum heat insulation plate 240 can be hung on the upper end cover 231 through cooperation of the clamping hooks.

[0116] In combination Figure 6 and Figure 7 In some embodiments of the present application, the vacuum heat insulation plate 240 and the door liner 210 have a first interval therebetween, and the first interval can be filled with foaming material. In this way, not only the heat preservation performance of the door body 200 can be improved, but also the foaming material can better fill the space between the vacuum heat insulation plate 240 and the door liner 210, so as to provide good support for the door liner 210 and reduce the risk of unevenness and deformation of the door liner 210.

[0117] In some embodiments, the first interval has a dimension along the thickness direction of the door body 200 that is not less than 10 mm. In this way, a larger interval between the vacuum heat insulation plate 240 and the door liner 210 can be ensured, so that the flow of the foaming material is smoother. If the dimension of the first interval is small, the flow of the foaming material can be affected, resulting in poor filling effect of the foaming material.

[0118] The dimension of the first interval along the thickness direction of the door body 200 is the dimension between the side of the vacuum heat insulation plate 240 facing the door liner 210 and the side of the door liner 210 facing the vacuum heat insulation plate 240 along the thickness direction of the door body 200. When the part of the door liner 210 is recessed towards the door panel 220, the first interval is the smallest interval between the vacuum heat insulation plate 240 and the door liner 210.

[0119] In some embodiments of the present application, the vacuum heat insulation plate 240 and the door panel 220 have a second interval. The second interval can be filled with foaming material. In this way, not only the heat preservation performance of the door body 200 can be improved, but also the foaming material can better fill the space between the vacuum heat insulation plate 240 and the door panel 220, providing good support for the door panel 220, reducing the problems such as shrinkage, unevenness, and sagging of the door panel 220, so that the door panel 220 can maintain a good appearance.

[0120] In some embodiments, the second interval has a dimension along the thickness direction of the door body 200 that is not less than 10 mm. In this way, a larger interval between the vacuum heat insulation plate 240 and the door panel 220 can be ensured, so that the flow of the foaming material is smoother. If the dimension of the first interval is small, the flow of the foaming material can be affected, resulting in poor filling effect of the foaming material.

[0121] In some possible implementations of the present application, the first interval can be equal to the second interval, so that the vacuum heat insulation plate 240 is located at the middle position of the door panel and the door liner 210 along the thickness direction of the door body 200, which is beneficial to ensuring the consistency of the foaming space on both sides of the vacuum heat insulation plate 240, and further improving the balance of the force received by the vacuum heat insulation plate 240.

[0122] Referring to Figure 7 The bottom end of the vacuum heat insulation plate 240 and the lower end cover 232 have an interval, which avoids interference between the lower end cover 232 and the vacuum heat insulation plate 240, and also allows the irregular space between the bottom end of the vacuum heat insulation plate 240 and the lower end cover 232 to be filled with foaming material, thereby improving the heat preservation performance of the door body 200.

[0123] Continuing to refer to Figure 6 and Figure 8, the vacuum heat insulation plate 240 is spaced apart from the two side end covers 233 along the width direction of the door body 200, so that interference between the vacuum heat insulation plate 240 and the side end cover 233 can be avoided, and irregular space between the vacuum heat insulation plate 240 and the side end cover 233 can be filled with foaming material, so that the heat preservation performance of the door body 200 is improved.

[0124] In some embodiments of the present application, the door body 200 can further include a foaming member, the foaming member can be filled in the first space and the second space, and the foaming member can also fill other space between the door panel 220 and the door liner 210.

[0144] The vacuum heat insulation plate 240 is at least partially accommodated in the hanging groove above the hanging hole 2421.

[0145] In some embodiments, the connecting portion 251, the hanging portion 252 and the limiting portion 253 are integrally formed as an integral piece, which is beneficial to ensure the structural strength and stability of the hook 250.

[0146] In some embodiments, the hook 250 and the upper end cover 231 are integrally formed as an integral piece, which is convenient for the forming of the hook 250 and the upper end cover 231.

[0147] The hook 250 of the embodiments of the present application is connected to the upper end cover 231 through the connecting portion 251, the vacuum heat insulation plate 240 is hung through the hanging portion 252, and the vacuum heat insulation plate 240 is limited to the hanging portion 252 through the limiting portion 253, which reduces the possibility of the vacuum heat insulation plate 240 coming off the hanging portion 252 and improves the reliability and stability of the vacuum heat insulation plate 240 hung on the hook 250.
