[0044] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of devices and methods consistent with some aspects of the utility model as detailed in the attached claims.

[0045] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0046] It should be understood that in the present utility model, "electrical connection" can be understood as the physical contact and electrical conduction of components; it can also be understood as the form in which different components in the circuit structure are connected through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals. "Communication connection" can refer to electrical signal transmission, including wireless communication connection and wired communication connection. Wireless communication connection does not require a physical medium and does not belong to a connection relationship that limits the product structure. "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship, that is, A is connected to B or A is connected to B, which can mean that there is a fastening component (such as screws, bolts, rivets, etc.) between A and B, or A and B are in contact with each other and A and B are difficult to separate.

[0047] Unless otherwise defined, all technical terms used in the embodiments of the present invention have the same meanings as commonly understood by those skilled in the art.

[0048] In refrigerator products of related art, a layer of foam material is usually filled in the interlayer of the shell, which plays a role of heat insulation and prevents the internal cold from penetrating outward. It can be said that the heat insulation effect of the foam material directly affects the working performance of the refrigerator. The heat insulation performance of the foam material is proportional to its thickness. Only when a certain thickness requirement is met, the foam material can play a sufficient heat insulation effect.

[0049] However, when the display module is set on the door of the refrigerator, the display module is usually built inside the inner body, and the display module will occupy the filling space of the foam material at the corresponding position, so that the thickness of the foam material at the corresponding position is smaller than that of other areas, and the thermal insulation performance is correspondingly reduced. The coldness inside the refrigerator will penetrate outward from this position, causing the temperature of the outer surface of the door at this position to decrease. When the temperature is lower than the moisture condensation temperature, the moisture in the external air will condense into dew on the outer surface of the door, affecting the normal use of the refrigerator. Dew may also invade the display module, causing problems such as electrical short circuits.

[0050] In addition, since the display module is usually made of plastic, the thermal conductivity of this material is usually low. The cold transferred to the display module cannot diffuse outward quickly, which will also aggravate the accumulation of cold energy, thereby aggravating the condensation problem at the corresponding position.

[0051] Therefore, the utility model provides a door assembly, which can avoid the cold accumulation at the display module therein, thereby preventing condensation.

[0052] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0053] On the one hand, combined with Figure 1 and Figure 7 As shown, this embodiment provides a door body assembly 100 , which includes: an inner plate body 1 , an outer plate body 2 , a display module 3 and a heat conduction assembly 4 .

[0054] The inner plate body 1 and the outer plate body 2 are connected to form a receiving space 001 , and the outer plate body 2 includes a display window 21 .

[0055] The display module 3 is located in the accommodating space 001 and is connected to the outer plate body 2, with the display surface 301 of the display module 3 facing the display window 21; the thermal conductive component 4 is located in the accommodating space 001, the thermal conductive component 4 corresponds to the position of the display module 3, and is connected to the inner side surface 201 of the outer plate body 2 facing the accommodating space 001.

[0056] In the door body assembly 100 of the present embodiment, at least part of the display module 3 is located in the accommodating space 001 surrounded by the inner panel body 1 and the outer panel body 2. In order to avoid local cold accumulation at the display module 3, a heat conductive component 4 is connected between the display module 3 and the inner side surface 201 of the outer panel body 2. The cold at the display module 3 is transferred to the outer panel body 2 through the heat conductive component 4, and then evenly dispersed outward by the outer panel body 2, thereby avoiding cold accumulation at the display module 3 and preventing condensation.

[0057] In some possible implementations, the display window 21 may be a transparent area on the outer plate 2 or a hollowed-out area on the outer plate 2. The display surface 301 of the display module 3 faces the display window 21, and information or images can be displayed outward through the display window 21.

[0058] Exemplarily, the display module 3 includes a box body 31 and a display module (not shown in the figure), the box body 31 is located in the accommodating space 001 and connected to the outer plate body 2, and the box body 31 is open on one side of the inner side 201 of the outer plate body 2 to accommodate the display module. The display module has a display surface 301 board, the display surface 301 is located on the display surface 301 board, and faces the above-mentioned display window 21.

[0059] In this embodiment, the position of the heat-conducting component 4 corresponds to that of the display module 3. Exemplarily, at least part of the heat-conducting component 4 is located between the display module 3 and the inner plate 1. When the cold energy on one side of the inner plate 1 is transferred toward the display module 3, since the heat-conducting component 4 is arranged on the transfer path of the cold energy, the heat-conducting component 4 will prevent the cold energy from continuing to be transferred toward the display module 3, but will guide the cold energy to the outer plate 2, and then evenly diffuse the cold energy through the outer plate 2, thereby ensuring that the temperature of each part of the outer plate 2 is relatively balanced, and can be maintained above the condensation temperature of the water, thereby preventing the condensation problem on the outer surface of the outer plate 2.

[0060] In some possible implementations, the heat-conducting component 4 may be directly connected to the display module 3 or may not be directly connected. Optionally, the heat-conducting component 4 is directly connected to the display module 3, so that when the accommodation space 001 is foamed and filled, since the heat-conducting component 4 is directly connected to the display module 3, it has better assembly stability, and the heat-conducting component 4 will not be displaced or jumped during the foaming process.

[0061] Combination Figure 2 As shown, in some embodiments, the orthographic projection of the heat conducting component 4 on the inner side surface 201 at least partially overlaps with the orthographic projection of the display module 3 on the inner side surface 201 .

[0062] Through the above arrangement, the direct projections of the heat conducting component 4 and the display module 3 on the inner side surface 201 of the outer plate body 2 at least partially overlap. In the overlapping portion, the heat conducting component 4 can block the transfer path between the inner plate body 1 and the display module 3, reduce or prevent the transfer of cold to the display module 3, and instead direct this part of the cold to the outer plate body 2, and then use the higher thermal conductivity of the outer plate body 2 to diffuse the cold, thereby preventing condensation on the outer surface of the outer plate body 2.

[0063] In some possible implementations, the orthographic projection of the heat-conducting component 4 and the orthographic projection of the display module 3 may be partially overlapped or completely overlapped.

[0064] Combination Figure 2 and Figure 4 As shown, in some embodiments, the display module 3 includes a first surface 302 and multiple second surfaces 303, the first surface 302 faces the inner plate body 1, one side of the second surface 303 is connected to the edge of the first surface 302, and the other side is connected to the inner side surface 201.

[0065] The heat-conducting assembly 4 includes a first heat-conducting member 41, and the first heat-conducting member 41 includes a first heat-conducting portion 411, a second heat-conducting portion 412 and a third heat-conducting portion 413. The first heat-conducting portion 411 faces the inner plate body 1, and the third heat-conducting portion 413 is located on the inner side surface 201 of the display module 3. One side of the second heat-conducting portion 412 is connected to the edge of the first heat-conducting portion 411, and the other side is connected to the edge of the third heat-conducting portion 413 close to the second surface 303.

[0066] The first heat conducting portion 411 corresponds to the position of the first surface 302 , the second heat conducting portion 412 corresponds to the position of the second surface 303 , and the third heat conducting portion 413 is heat-conductingly connected to the inner side surface 201 of the peripheral side of the display module 3 .

[0067] In this embodiment, the first heat conducting part 411 of the first heat conducting member 41 is arranged correspondingly on the first surface 302 of the display module 3, which can cut off the main path of the transfer of cold energy toward the display module 3, and guide the cold energy to the outer plate 2 through the second heat conducting part 412 and the third heat conducting part 413, which can effectively reduce the cold energy accumulation at the corresponding position of the display module 3.

[0068] In some possible implementations, the outer plate body 2 has a relatively high thermal conductivity. Exemplarily, the outer plate body 2 is a metal outer plate.

[0069] In some other possible implementations, the display module 3 is in the shape of a cuboid, the first surface 302 and the display surface 301 have the same area and are located opposite to each other, and the display surface 301 is located at the front of the display module 3, then the first surface 302 is located at the back of the display module 3, and the second surface 303 is located at the side of the display module 3. Optionally, the first surface 302 and the second surface 303 are both rectangular. Correspondingly, the first heat conducting portion 411 and the first surface 302 have the same shape, and the second heat conducting portion 412 and the second surface 303 have the same shape, that is, the first heat conducting portion 411 and the second heat conducting portion 412 are also rectangular.

[0070] In addition, the third heat conducting portion 413 is located on the inner side surface 201 of the peripheral side of the display module 3 , and the third heat conducting portion 413 is a rectangular ring surrounding the orthographic projection of the display module 3 on the inner side surface 201 , or a part of the rectangular ring.

[0071] Combination Figure 2 and Figure 5 As shown, in some embodiments, the heat-conducting component 4 also includes a second heat-conducting member 42, one side of the second heat-conducting member 42 is heat-conductingly connected to the inner side surface 201 of the peripheral side of the display module 3, and the other side of the second heat-conducting member 42 is heat-conductingly connected to the third heat-conducting portion 413, and the thermal conductivity of the first heat-conducting member 41 is greater than the thermal conductivity of the second heat-conducting member 42.

[0072] Through the above arrangement, the cold intercepted by the first heat-conducting member 41 will first be transferred to the second heat-conducting member 42, but because the thermal conductivity of the second heat-conducting member 42 is relatively small, the rate at which the cold is transferred toward the outer plate body 2 is reduced. After the rate at which the outer plate body 2 receives the cold is reduced, it has enough time to diffuse the cold, and even if the thermal conductivity of the outer plate body 2 is slightly worse, it will not cause the problem of cold accumulation. In addition, because the thermal conductivity of the second heat-conducting member 42 is relatively small, part of the cold will be forced to diffuse on the second heat-conducting member 42 in a direction parallel to the inner side surface 201 of the outer plate body 2, and then slowly transferred toward the outer plate body 2, which further reduces the risk of cold accumulation on the surface of the outer plate body 2.

[0073] In some possible implementations, the thermal conductivity of the outer plate 2 is low. For example, the outer plate 2 is a glass outer plate. By arranging the second heat-conducting member 42 between the first heat-conducting member 41 and the glass outer plate, the cold energy on the surface of the glass outer plate can be effectively prevented from accumulating, and condensation can be avoided on the surface of the glass outer plate.

[0074] Combination Figure 1 and Figure 6 As shown, in some embodiments, the heat conductive component 4 also includes a third heat conductive member 43, one side of the third heat conductive member 43 is heat-conductingly connected to the second heat conductive member 42, the other side of the third heat conductive member 43 is heat-conductingly connected to the third heat conductive portion 413, and the thermal conductivity of the third heat conductive member 43 is greater than the thermal conductivity of the second heat conductive member 42.

[0075] In order to further improve the diffusion effect of cold energy at the second heat-conducting member 42, the third heat-conducting member 43 is arranged between the second heat-conducting member 42 and the first heat-conducting member 41 in this embodiment. The thermal conductivity of the third heat-conducting member 43 is greater than that of the second heat-conducting member 42. Therefore, the cold energy transferred from the first heat-conducting member 41 will be preferentially expanded and transferred on the third heat-conducting member 43 in a direction parallel to the inner side surface 201, and then transferred toward the second heat-conducting member 42, which can further prevent the cold energy from being concentratedly transferred to the outer plate body 2, resulting in the problem of local cold energy accumulation in the outer plate body 2.

[0076] Combination Figure 6 As shown, in some embodiments, the orthographic projection area S3 of the third heat conductor 43 on the inner side surface 201 is larger than the orthographic projection area S1 of the third heat conductor portion 413 on the inner side surface 201 , and is smaller than or equal to the orthographic projection area S2 of the second heat conductor 42 on the inner side surface 201 .

[0077] Through the above arrangement, the third heat conductor 43 can disperse the cold transferred from the third heat conducting portion 413 to a larger area, and then transfer it toward the second heat conductor 42, further improving the cold diffusion transfer effect of the heat conducting component 4.

[0078] In some possible implementations, reference Figure 2 and Figure 3 As shown, the first heat conducting part 411 is attached to the first surface 302, the second heat conducting part 412 is attached to the second surface 303, and the third heat conducting part 413, the third heat conducting member 43, the second heat conducting member 42 and the inner side surface 201 are attached in sequence. The attachment and connection of the above structures can improve the cold transfer effect between each other on the one hand, and on the other hand, can reduce the assembly difficulty of the above structures, which is conducive to improving the assembly efficiency.

[0079] In some embodiments, the first heat conducting member 41 and the third heat conducting member 43 are both metal foil structures, such as aluminum foil structures, and the second heat conducting member 42 is a sponge structure. Using metal foil structures as the first heat conducting member 41 and the third heat conducting member 43 can ensure rapid transfer of cold energy on the first heat conducting member 41 and the third heat conducting member 43, and using a sponge structure as the second heat conducting member 42 can ensure that cold energy is transferred relatively slowly from the second heat conducting member 42 to the outer plate 2, thereby preventing cold energy from accumulating on the outer plate 2.

[0080] Combination Figure 1 and Figure 6 As shown, in some embodiments, the heat-conducting component 4 is a composite heat-insulating cotton 44, and the composite heat-insulating cotton 44 includes a sponge layer and a metal foil layer, the sponge layer is formed as the second heat-conducting member 42, and the metal foil layer is formed as the third heat-conducting member 43. By using the sponge layer and the metal foil layer of the composite heat-insulating cotton 44 as the second heat-conducting member 42 and the third heat-conducting member 43, respectively, the structure of the heat-conducting component 4 can be simplified, and the second heat-conducting member 42 and the third heat-conducting member 43 are assembled as one body, reducing the difficulty of assembling the heat-conducting component 4.

[0081] Combination Figure 1 and Figure 6 As shown, in some embodiments, the composite thermal insulation cotton 44 includes a first part 441, a second part 442 and a third part 443 connected in a U shape, the first part 441 and the third part 443 are respectively located on the left and right sides of the display module 3, and the second part 442 is located below the display module 3.

[0082] Through the above arrangement, the U-shaped composite heat insulation cotton 44 can surround the left and right sides and the bottom of the display module 3, which can reduce the difficulty of installation and positioning of the composite heat insulation cotton 44 and prevent cold accumulation on the outer plate 2 around the display module 3. In addition, the composite heat insulation cotton 44 is closely arranged with the display module 3, which can reduce the occupation of the accommodation space 001, increase the foaming filling space, and ensure the filling effect of the foaming material.

[0083] On the other hand, combined Figure 8 As shown, this embodiment provides a refrigerator, and the refrigerator includes the door assembly 100 of the utility model. The refrigerator of this embodiment adopts the door assembly 100 of the utility model and has all the beneficial technical effects of all the embodiments of this invention.

[0084] In some possible implementations, reference Figure 8 As shown, the refrigerator further includes a cabinet assembly 200 , and the door assembly 100 is rotatably connected to the cabinet assembly 200 .
